However, unless the Employee is employed by the Sponsor at its plant in Lincolnshire, Illinois, an Employee who is included in a unit of Employees covered by a collective bargaining agreement between the Employees’ representative and the Employer is not eligible to participate in the Plan if there has been good faith bargaining between the Employer and the Employees’ representative pertaining to retirement benefits and the agreement does not require the Employer to include such Employees in the Plan. In addition, a Leased Employee shall not be eligible to participate in the Plan unless the Plan’s qualified status is dependent upon coverage of the Leased Employee. An Employee who is a nonresident alien (within the meaning of section 7701(b) of the Code) and receives no earned income (within the meaning of section 911(d)(2) of the Code) from any Affiliated Employer that constitutes income from sources within the United States (within the meaning of section 861(a)(3) of the Code) is not eligible to participate in the Plan. An Employee who is a nonresident alien (within the meaning of section 7701(b) of the Code) and who does receive earned income (within the meaning of section 911(d)(2) of the Code) from any Affiliated Employer that constitutes income from sources within the United States (within the meaning of section 861(a)(3) of the Code) all of which is exempt from United States income tax under an applicable tax convention is not eligible to participate in the Plan. During any period in which an individual is classified by an Employer as an independent contractor with respect to such Employer, the individual is not eligible to participate in the Plan (even if he is subsequently reclassified by the Internal Revenue Service as a common law employee of the Employer and the Employer acquiesces to the reclassification). During any period in which an individual is classified by an Employer as an intern or student with respect to such Employer, the individual is not eligible to participate in the Plan. Finally, an Employee who is employed outside the United States is not eligible to participate in the Plan unless the Committee elects to permit him to participate in the Plan. Notwithstanding any other provision of the Plan to the contrary, (1) an Employee of Imperial Products, Inc. who was employed by Imperial Products, Inc. on April 1, 2000, shall be eligible to participate in the Plan on June 1, 2000, (2) an Employee of Colonial Craft, Inc, who was employed by Colonial Craft, Inc. on February 2, 2002 shall be eligible to participate in the Plan on February 2, 2002 and (3) an Employee of the Sponsor employed primarily in connection with its Piper Impact division on December 1, 2005 shall be eligible to participate in the Plan on December 1, 2005.

2.02 Early Participation for Some Purposes. An Employee who satisfies the eligibility requirements specified in Section 2.01 other than the service requirement shall be eligible to participate in the cash or deferred arrangement portion of the Plan for all purposes relating to Salary Deferral Contributions and he shall be eligible to make Rollover Contributions to the Plan, in both cases, on the Entry Date next following (not coincident with) the date on which he completes an Hour of Service.

II-1

2.03 Eligibility Upon Reemployment. If an Employee incurs a Separation From Service prior to the date he initially begins participating in the Plan, he shall be eligible to begin participation in the Plan on the later of the date he would have become a Participant if he did not incur a Separation From Service or the date on which he performs an Hour of Service after he incurs a Separation From Service. Subject to Section 2.04, once an Employee becomes a Participant, his eligibility to participate in the Plan shall continue until he Severs Service.

2.04 Cessation of Participation. An individual who has become a Participant will cease to be a Participant on the earliest of the date on which he (a) Severs Service, (b) is transferred from the employ of an Employer to the employ of an Affiliated Employer that has not adopted the Plan, (c) becomes included in a unit of employees covered by a collective bargaining agreement that does not require coverage of those employees under the Plan, (d) becomes a Leased Employee, or (e) becomes included in another classification of Employees who, under the terms of the Plan, are not eligible to participate.

CONTRIBUTIONS

3.01 Salary Deferral Contributions. Each Employer shall make a Salary Deferral Contribution in an amount equal to the amount by which the Considered Compensation of its Employees who are Participants was reduced on a pre-tax basis pursuant to salary deferral agreements (excluding amounts of Considered Compensation deferred pursuant to Section 3.02 that are properly characterized as Catch-up Salary Deferral Contributions). Any such salary deferral agreement shall be an agreement in a form satisfactory to the Committee to prospectively receive Considered Compensation from the Employer in a reduced amount and to have the Employer contribute an amount equal to the amount of the reduction to the Trust on account of the Participant. Any such salary deferral agreement shall be revocable in accordance with its terms, provided that no revocation shall be retroactive or permit payment to the Participant of the amount required to be contributed to the Trust. A Participant’s right to benefits attributable to Salary Deferral Contributions made to the Plan on his behalf shall be nonforfeitable.

The maximum amount a Participant may elect to reduce his Considered Compensation under his salary deferral agreement and have contributed to the Plan on a pre-tax basis shall be determined by the Committee, in its sole discretion from time to time. The election to have Salary Deferral Contributions made, the ability to change the rate of Salary Deferral Contributions, the right to suspend Salary Deferral Contributions, and the manner of commencing new Salary Deferral Contributions shall be permitted under any uniform method determined by the Committee from time to time.

3.02 Catch-up Salary Deferral Contributions. The Employer shall make a Catch-up Salary Deferral Contribution in an amount equal to the amounts by which its Catch-up Eligible Participants’ Considered Compensation was reduced as a result of salary deferral agreements authorizing Catch-up Salary Deferral Contributions (to the extent that their deferrals are properly characterized as Catch-up Salary Deferral Contributions). Any such salary deferral agreement shall be an agreement in a form satisfactory to the Committee to prospectively receive Considered Compensation from the Employer in a reduced amount and to have the Employer contribute an amount equal to the amount of the reduction to the Trust on behalf of the Catch-up Eligible Participant. Further, any such salary deferral agreement shall be revocable in accordance with its terms, provided that no revocation shall be retroactive or permit payment to the Catch-up Eligible Participant of the amount required to be contributed to the Trust. A Catch-up Eligible Participant’s right to benefits derived from Catch-up Salary Deferral Contributions made to the Plan on his behalf shall be nonforfeitable.

Catch-up Salary Deferral Contributions on behalf of a Catch-up Eligible Participant shall be permitted to the extent that the Catch-up Salary Deferral Contributions do not exceed the lesser of (a) the “applicable dollar amount” under section 414(v) of the Code for the Plan Year (as adjusted from time to time by the Secretary of Treasury), or (b) an amount equal to the Catch-up Eligible Participant’s Annual Compensation for the Plan Year minus the Catch-up Eligible Participant’s Salary Deferral Contributions for the Plan Year.

III-1

A final determination as to whether amounts deferred under the Plan by a Catch-up Eligible Participant are properly characterized as Salary Deferral Contributions or Catch-up Salary Deferral Contributions for a Plan Year shall be made as of the end of the Plan Year. To the extent that amounts deferred under the Plan on a pre-tax basis at the election of a Catch-up Eligible Participant exceed the least of (a) the lowest statutory limit on Salary Deferral Contributions (including limits imposed under sections 401(a)(30) and 415 of the Code), (b) the maximum limitation on Salary Deferral Contributions, if any, imposed by the Committee pursuant to Section 3.01, or (c) the highest amount of Salary Deferral Contributions on behalf of the Catch-up Eligible Participant that may be retained in the Plan under the rules of section 401(k)(8)(C) of the Code, the amounts deferred shall be characterized as Catch-up Salary Deferral Contributions. Any amounts deferred under the Plan on a pre-tax basis at the election of a Catch-up Eligible Participant that are not properly characterized as Catch-up Salary Deferral Contributions pursuant to the rules of the preceding sentence shall be characterized as Salary Deferral Contributions for all purposes under the Plan.

3.03 Matching Contributions. Except with respect to Employees who are included in a unit of employees covered by a collective bargaining agreement between the Employers’ representative and the Sponsor and are employed at the Sponsor’s plant in Lincolnshire, Illinois, each Employer will make a Matching Contribution on behalf of each of its Employees who is a Participant in an amount equal to 50 percent of the first five percent of such Participant’s Considered Compensation for periods after March 31, 2001 contributed to the Plan pursuant to such Participant’s Salary Deferral Contributions and Catch-up Salary Deferral Contributions.

3.04 Supplemental Contributions for Hourly Employees Other Than Employees of Nichols Aluminum-Alabama, Inc., Temroc Metals, Inc., Imperial Products, Inc. and Colonial Craft, Inc. Each Employer other than Nichols Aluminum-Alabama, Inc., Temroc Metals, Inc., Imperial Products, Inc. and Colonial Craft, Inc. may contribute for an Allocation Period a Supplemental Contribution to be allocated among Employees who receive hourly remuneration and are eligible to participate in the Plan in such amount, if any, as shall be determined by the Employer. The rate of the Supplemental Contribution need not be uniform among all divisions of the Employer. Unless the Employer determines otherwise by a resolution of its board of directors, the Employer shall not make a Supplemental Contribution to the Plan for an Allocation Period on behalf of its Employees who are compensated on an hourly basis and are eligible to participate in the Plan unless during the fiscal year of the Sponsor immediately preceding the Allocation Period the Sponsor had positive Earnings Before Interest and Taxes.

3.05 Supplemental Contributions for Salaried Employees Other Than Employees of Nichols Aluminum-Alabama, Inc., Temroc Metals, Inc., Imperial Products, Inc. and Colonial Craft, Inc.

3.07 Rollover Contributions and Plan-to-Plan Transfers. The Committee may permit Rollover Contributions by Participants and/or direct transfers to or from another qualified plan on behalf of Participants from time to time. If Rollover Contributions and/or direct transfers to or from another qualified plan are permitted, the opportunity to make those contributions and/or direct transfers must be made available to Participants on a nondiscriminatory basis. For this purpose only, all Employees who are included in a classification of Employees who are eligible to participate in the Plan shall be considered to be Participants of the Plan even though they may not have met the Active Service requirements for eligibility. However, they shall not be entitled to elect to have Salary Deferral Contributions made or to share in Employer Contributions or forfeitures unless and until they have met the requirements for eligibility, contributions and allocations. A Rollover Contribution shall not be accepted unless it is directly rolled over to the Plan in a rollover described in section 401(a)(31) of the Code. A Participant shall not be permitted to make a Rollover Contribution if the property he intends to contribute is for any reason unacceptable to the Trustee. A Participant’s right to benefits attributable to his Rollover Contributions made to the Plan shall be nonforfeitable.

3.08 QNECS - Extraordinary Employer Contributions. Any Employer may make a QNEC in such amount, if any, as shall be determined by it. A Participant’s right to benefits attributable to QNECs made to the Plan on his behalf shall be nonforfeitable. In no event will QNECs be distributed before Salary Deferral Contributions may be distributed from the Plan.

3.09 Restoration Contributions. The Employer shall, for each Plan Year, make a restoration contribution in an amount equal to the sum of (a) such amount, if any, as shall be necessary to fully restore all Matching Contribution Accounts and Supplemental Contribution Accounts required to be restored pursuant to the provisions of Section 9.02 after the application of all forfeitures available for such restoration; plus (b) an amount equal in value to the value of forfeited benefits required to be restored under Section 9.03, after the application of all forfeitures available for such restoration.

3.10 Restorative Payments. If due to an oversight or inadvertent error an Employer fails to make a Contribution to the Plan on behalf of an Employee, as soon as administratively practicable following the Employee’s discovery of the error, the Employer shall make a restorative payment to the Plan on behalf of the Employee in an amount equal to the amount of required Contributions the Employer should have made to the Plan on behalf of the Employee plus interest thereon (both determined in a manner that is consistent with then current guidance from the Department of Treasury concerning such restorative payments) after the application of forfeitures available for such restoration.

III-3

3.11 Nondeductible Contributions Not Required. Notwithstanding any other provision of the Plan, no Employer shall be required to make any contribution that would be a “nondeductible contribution” within the meaning of section 4972 of the Code.

3.12 Form of Payment of Contributions. Contributions may be paid to the Trustee either in cash or in qualifying employer securities (as such term is defined in section 407(d) of ERISA) or any combination thereof, provided that payment may not be made in any form constituting a prohibited transaction under section 4975 of the Code or section 406 of ERISA.

3.13 Deadline for Payment of Contributions. Salary Deferral Contributions and Catch-up Salary Deferral Contributions shall be paid to the Trustee in installments. The installment for each payroll period shall be paid as soon as administratively feasible. The Matching Contributions, Supplemental Contributions and QNECs for a Plan Year shall be paid to the Trustee in one or more installments, as the Employer may from time to time determine; provided, however, that such contributions may not be paid later than the time prescribed by law (including extensions thereof) for filing the Employer’s income tax return for its taxable year ending with or within such Plan Year.

3.14 Return of Contributions for Mistake, Disqualification or Disallowance of Deduction. Subject to the limitations of section 415 of the Code, the assets of the Trust shall not revert to any Employer or be used for any purpose other than the exclusive benefit of Participants, former Participants and their Beneficiaries and the reasonable expenses of administering the Plan except:

(a) any Employer Contribution made because of a mistake of fact may be repaid to the Employer within one year after the payment of the Contribution; and

(b) all Employer Contributions are conditioned upon their deductibility under section 404 of the Code; therefore, to the extent the deduction is disallowed, the Contributions may be repaid to the Employer within one year after the disallowance.

The Employer has the exclusive right to determine if a Contribution or any part of it is to be repaid or is to remain as a part of the Trust except that the amount to be repaid is limited, if the Contribution is made by mistake of fact or if the deduction for the Contribution is disallowed, to the excess of the amount contributed over the amount that would have been contributed had there been no mistake or over the amount disallowed. Earnings which are attributable to any excess contribution cannot be repaid. Losses attributable to an excess contribution must reduce the amount that may be repaid. All repayments of Contributions made due to a mistake of fact or with respect to which a deduction is disallowed are limited so that the balance in a Participant’s or former Participant’s Account cannot be reduced to less than the balance that would have been in the Participant’s or former Participant’s Account had the mistaken amount or the amount disallowed never been contributed.

3.15 Special Rule for Employees of the Piper Impact Divisions. Employees eligible to participate in the Plan because they are employed by the Sponsor in connection with its Piper Impact division are not entitled to Supplemental Contributions under Sections 3.04, 3.05 or 3.06.

Such schedules shall be conclusive evidence of such facts.

4.02 Allocation of Salary Deferral Contributions. The Committee or its designee shall allocate the Salary Deferral Contribution among the Participants by allocating to each Participant the amount by which his Considered Compensation was reduced pursuant to a salary deferral agreement (as described in Section 3.01) and shall credit each such Participant’s share to his Salary Deferral Contribution Account.

4.03 Allocation of Catch-up Salary Deferral Contribution.

4.04 Allocation of Matching Contributions. The Committee or its designee shall separately allocate the Matching Contribution made by an Employer among the Employer’s Participants in the proportion which the matched Salary Deferral Contributions and matched Catch-up Salary Deferral Contributions of each such Participant bear to the total matched Salary Deferral Contributions and matched Catch-up Salary Deferral Contributions of all such Participants. Each Participant’s proportionate share shall be credited to his Matching Contribution Account.

4.05 Allocation of Supplemental Contributions. For each Allocation Period, the Committee shall allocate the Supplemental Contribution, if any, made by an Employer on behalf of Participants or former Participants who receive hourly remuneration from the Employer (or in connection with a division specified by the Employer) for the Allocation Period among the Participants or former Participants who (1) are eligible to participate in the Plan, (2) receive hourly remuneration, (3) are employed by the Employer (or in connection with a division specified by the Employer) with respect to which the Supplemental Contribution is made, (4) are entitled to a Supplemental Contribution under Section 3.4 and (5) are employed by the Employer (or in connection with a division specified by the Employer) during the Allocation Period based upon each such Participant’s or former Participant’s Considered Compensation paid by the Employer as compared to the Considered Compensation for all such Participants or former Participants employed by the Employer and eligible for the allocation applicable to that division of the Employer under Section 3.04.

IV-1

4.07 Allocation of Forfeitures. At the time a forfeiture occurs pursuant to Article VIII, Section A.3.2 of Appendix A or Section A.3.3 of Appendix A, the amount forfeited will first be used to reinstate any Account required to be reinstated under Article IX, and any remaining amount will be applied to reduce the Employer’s obligation to make future Matching Contributions or Supplemental Contributions. However, in no event will amounts forfeited pursuant to Section A.3.2 or Section A.3.3 of Appendix A be allocated to the Accounts of Participants whose Matching Contributions are forfeited pursuant to Section A.3.2 or Section A.3.3 of Appendix A.

BENEFITS

5.01 Retirement Benefit. Upon his Separation From Service, a Participant or former Participant is entitled to receive his Nonforfeitable Interest in his Account balances.

5.02 Death Benefit. If a Participant or former Participant dies, the death benefit payable to his Beneficiary shall be the Participant’s Nonforfeitable Interest in 100 percent of the remaining amount of his Account balances.

5.03 Form of Distribution. Any distribution under the Plan shall be made in the form of a cash lump sum. However, a Participant who accrued any benefits under the Decatur Plan has the right to elect to receive payments in the form of property instead of cash, but only with respect to his Decatur Plan account balances that were transferred to the Plan.

5.04 Distribution Methods. Subject to Sections 5.05 and 5.11, the distribution methods available under the Plan are (a) a lump sum payment and (b) periodic installment payments.

If a Participant or former Participant elects periodic installments payments, his Account balances shall be paid in substantially equal monthly, quarterly, semi-annual or annual periodic installments (as elected by him) for a specified number of years which may not exceed his life expectancy or the joint and last survivor life expectancy of him and his Beneficiary. Life expectancies will be determined, under Regulations issued under section 79 of the Code, as of the time payments commence. If installments are elected, the Committee may direct that the Participant’s or former Participant’s interest in the Plan be segregated and invested separately. Upon the death of a Participant or former Participant prior to the complete distribution of his Account balances, his Beneficiary may elect to receive the Beneficiary’s interest in the Account in (a) an immediate lump sum cash payment or (b) installment payments for any period not in excess of the period (if any) selected by the Participant or former Participant.

Notwithstanding the foregoing, until July 1, 2001, the only distribution method available for a Participant who was a participant in the Temroc Plan is a lump sum payment.

Notwithstanding the foregoing, if a Participant is only eligible to participate in the Plan because he is employed by the Sponsor in connection with its Piper Impact division, the only distribution method available for such a Participant is a lump sum payment.

5.05 Immediate Payment of Small Amount Upon Separation From Service. Effective as of March 28, 2005, each Participant or former Participant whose Nonforfeitable Interest in his Account balance at the time of a distribution to him on account of his Separation From Service is, in the aggregate, less than or equal to $1,000.00, shall be paid in the form of an immediate single sum cash payment and/or as a Direct Rollover, as elected by him under section 5.06. However, if a Distributee who is subject to this Section 5.04 does not furnish instructions in accordance with Plan procedures to directly roll over his Plan benefit within 45 days after he has been given direct rollover forms, he will be deemed to have elected to receive an immediate lump sum cash distribution of his entire Plan benefit. If a Participant’s or former Participant’s

V-1

Nonforfeitable Interest in his Account balance payable upon his Separation From Service is zero (because he has no Nonforfeitable Interest in his Account balance), he will be deemed to have elected and to have received an immediate distribution of his entire Nonforfeitable Interest in his Account balance.

5.06 Direct Rollover Option. To the extent required under Regulations, a Distributee has the right to direct that any portion of his Eligible Rollover Distribution will be directly paid to an Eligible Retirement Plan specified by him that will accept the Eligible Rollover Distribution.

5.07 Consent to Distribution. Notwithstanding any other provision of the Plan, no benefit shall be distributed or commence to be distributed to a Participant or former Participant prior to his attainment of the later of age 62 or Retirement Age without his consent, unless the benefit is payable immediately under Section 5.05. Any such consent shall be valid only if given not more than 90 days prior to the Participant’s or former Participant’s Annuity Starting Date and after his receipt of the notice regarding benefits described in Section 5.10(a).

5.08 QJSA Requirements. On and after the date on which the Sponsor elects to treat the Plan and the Quanex Corporation Salaried Employees’ Pension Plan as one plan for purposes of section 410(b) of the Code, this Section 5.08 will apply. Except for small benefits payable under Section 5.05, each Participant or former Participant who (a) is married on his Annuity Starting Date and (b) does not die before his Annuity Starting Date will be paid in the form of a QJSA, unless he and his Spouse make a valid election to waive this form of payment. Except for small benefits payable under Section 5.05, each other Participant who does not die before the Annuity Starting Date, will be paid in the form of a life only annuity unless he makes a valid election to waive this form of payment. A Participant’s waiver of the QJSA form of payment will not be effective unless the waiver (1) designates a specific nonspouse Beneficiary who will receive Plan benefits and (2) specifies the particular optional form of benefits selected instead of the QJSA. Also, a Participant’s or former Participant’s waiver of the QJSA will not be effective unless his Spouse signs either a specific or a general consent to his waiver. A specific spousal consent must (1) be in writing, (2) consent to the waiver of the QJSA, (3) consent to the specific nonspouse Beneficiary designated by the Participant or former Participant to receive Plan benefits, (4) consent to the particular optional form of benefit selected by the Participant or former Participant, (5) acknowledge the effect of the Spouse’s consent to the Participant’s or former Participant’s waiver of the QJSA, and (6) be witnessed by a notary public or a Plan representative. A general spousal consent must (1) be in writing, (2) consent to the Participant’s or former Participant’s waiver of the QJSA, (3) specify that the Participant or former Participant can change the Beneficiary designated by him to receive Plan benefits, without any requirement of further consent by the Spouse, (4) specify that the Participant or former Participant can change the optional form of benefit elected by the Participant or former Participant, without any requirement of further consent by the Spouse, (5) acknowledge that the Spouse has the right to limit consent to a specific Beneficiary and a specific optional form of benefit, and that the Spouse voluntarily elects to relinquish both of those rights, (6) acknowledge the effect of the Spouse’s consent to the Participant’s or former Participant’s waiver of the QJSA, and (7) be witnessed by a notary public or a Plan representative. However, a Participant’s or former Participant’s election to waive the QJSA shall be effective if it is established to the satisfaction of the Committee that spousal consent to his waiver may not be obtained because (1) there is no

V-2

Spouse, (2) the Spouse cannot be located, or (3) there exist such other circumstances which obviate the necessity of obtaining the spousal consent. Any consent by the Participant’s or former Participant’s Spouse (or establishment that the consent of the Participant’s or former Participant’s Spouse may not be obtained) shall be effective only with respect to such Spouse.

5.09 QPSA Requirements.

(a) General Rules. On and after the date on which the Sponsor elects to treat the Plan and the Quanex Corporation Salaried Employees’ Pension Plan as one plan for purposes of section 410(b) of the Code, this Section 5.09 will apply. Except for small benefits payable under Section 5.05, the death benefit of a Participant or former Participant who (1) is married on the date of his death and (2) dies before his Annuity Starting Date will be paid in the form of a QPSA, unless he and his Spouse make a valid election to waive this form of payment. Subject to Section 5.12, the surviving Spouse of such a Participant or former Participant may elect to have payments commence to her as soon as administratively practicable, or at any later date selected by her.

(b) Waivers. Any valid election to waive the QPSA must be made in writing by the Participant or former Participant and consented to by the Participant’s or former Participant’s Spouse. Any spousal consent to the waiver must: (1) be witnessed by a member of the Committee, the Trustee, or a notary public, and (2) consent to the specific nonspouse Beneficiary or Beneficiaries selected by the Participant or former Participant (or permit future changes in designations by the Participant or former Participant provided that general consent requirements similar to those described in Section 5.08 are satisfied). However, if the Participant or former Participant establishes to the satisfaction of the Committee or the Trustee that the spouse’s written consent cannot be obtained because there is no Spouse or the Spouse cannot be located, a waiver signed only by the Participant or former Participant will be considered a valid election. The consent to a waiver is valid only with respect to the Spouse who signs it; therefore, if the Participant or former Participant remarries after executing a waiver, the Participant’s or former Participant’s new Spouse must execute a new consent. The Participant or former Participant may revoke a prior waiver without his Spouse’s consent at any time before benefit payments begin. Except as specified below, an election to waive the QPSA will be valid only if it is made after the first day of the Plan Year in which the Participant or former Participant attains age 35 and before the Participant’s or former Participant’s death.

(c) Pre-Age 35 Waivers. A Participant or former Participant may waive the QPSA, with spousal consent, before the first day of the Plan Year in which he attains age 35 if the Sponsor provides him a written explanation of the QPSA (that meets the requirements of Section 5.10(e)) within the period beginning one year before he Severs Service and ending one year after he Severs Service. However, any such waiver will expire and become invalid beginning on the first day of the Plan Year in which the Participant or former Participant attains age 35.

V-3

5.10 Information Provided to Participants. Information regarding the form of benefits available under the Plan shall be provided to Participants or former Participants in accordance with the following provisions:

(a) QJSA Notice and Notice of Right to Defer Receipt of Distribution. Except as otherwise provided in paragraph (c), the Sponsor shall provide a Participant or former Participant a written notice explaining the terms and conditions of each retirement option and the Participant’s or former Participant’s right to defer receipt of the Participant’s or former Participant’s distribution. On and after the date on which an Employer elects to treat the Plan and the Quanex Corporation Salaried Employees’ Pension Plan as one plan for purposes of section 410(b) of the Code, the Sponsor shall also provide a Participant or former Participant a written notice explaining (1) the QJSA requirements under Section 5.08 (including: (i) the Participant or former Participant’s right to make, and the effect of, a waiver of the QJSA, (ii) the right of the Participant or former Participant’s Spouse to consent or not to consent to such a waiver and (iii) the right to make, and the effect of, a revocation of a previous waiver or election) and (2) the eligibility conditions and other material features of the optional forms of benefit. The notice shall also either contain (1) a description, that is specific to the Participant or former Participant, of the financial effect of the Participant or former Participant selecting an optional form of benefit or (2) a general description of the financial effect of the election that complies with the requirements of Department of Treasury Regulations issued under section 417 of the Code. If a general description of the financial effect of the election is included in the notice, the notice must also be accompanied by a statement that includes an offer to provide, upon the Participant or former Participant’s request, a statement of financial effect and a description of how the Participant or former Participant may obtain this additional information. The notice shall also either contain (1) a description, that is specific to the Participant or former Participant, of the relative values of the optional forms of benefit compared to the value of the QJSA or (2) a general description of the relative values that complies with the requirements of Department of Treasury Regulations issued under section 417 of the Code. If a general description of the relative values is included in the notice, the notice must also be accompanied by a statement that includes an offer to provide, upon the Participant or former Participant’s request, a comparison of relative values that is specific to the Participant or former Participant for any presently available optional form of benefit and a description of how the Participant or former Participant may obtain this additional information. The notice requirements set forth in this paragraph (a) are collectively referred to as the “QJSA Notice”.

(b) Time for Giving Notice. Except as specified below in this paragraph (b) or as permitted under paragraph (d), the QJSA Notice shall be provided to a Participant or former Participant no less than thirty days and no more than ninety days before his Annuity Starting Date. If the Participant or former Participant, after having received the QJSA Notice, affirmatively elects a form of distribution with the consent of the Participant or former Participant’s Spouse (if necessary), the thirty-day timing requirement of this paragraph (b) will not apply if all of the following conditions are satisfied: (1) the Sponsor informs the Participant or former Participant in writing that the Participant or former Participant has a right to at least thirty days to consider whether to waive the QJSA and consent to a form of distribution other than a QJSA, (2) the

V-4

Participant or former Participant is permitted to revoke an affirmative distribution election at least until the Annuity Starting Date, or, if later, at any time prior to the expiration of the seven-day period that begins the day after the QJSA Notice is provided to the Participant or former Participant, (3) the Annuity Starting Date is after the date the QJSA Notice is provided to the Participant or former Participant, and (4) a distribution of the Participant or former Participant’s benefit in accordance with the Participant or former Participant’s affirmative election does not commence before the expiration of the seven-day period that begins the day after the QJSA Notice is provided to the Participant or former Participant. The ninety-day timing requirement of this paragraph (b) will not be failed merely because, due solely to administrative delay, a distribution commences more than ninety days after the QJSA Notice is provided to the Participant or former Participant.

(c) Exception for Participants with Small Benefit Amounts. Notwithstanding the preceding provisions of this Section, no QJSA Notice shall be provided to the Participant or former Participant if his benefit is payable in a lump sum under Section 5.05.

(d) QPSA Notice. This paragraph applies on and after the date on which an Employer elects to treat the Plan and the Quanex Corporation Salaried Employees’ Pension Plan as one plan for purposes of section 410(b) of the Code. The Sponsor will provide each Participant or former Participant who is subject to Section 5.09 a written explanation of: (a) the terms and conditions of the QPSA, (b) the Participant’s or former Participant’s right to waive the QPSA and the effect of the waiver, (c) the rights of the Participant’s or former Participant’s Spouse, and (d) the right to revoke a prior waiver and the effect of the revocation. This written explanation will be provided within the latest of the period (a) beginning on the first day of the Plan Year in which the Participant or former Participant attains age 32 and ending with the close of the Plan Year preceding the Plan Year in which the Participant or former Participant attains age 35, (b) ending one year after the individual becomes a Participant, or (c) ending one year after the QPSA rules first become effective with respect to the Participant or former Participant.

5.11 Optional Forms of Distribution. On and after the date on which the Sponsor elects to treat the Plan and the Quanex Corporation Salaried Employees’ Pension Plan as one plan for purposes of section 410(b) of the Code, all of the optional forms of payment available under the Quanex Corporation Salaried Employees’ Pension Plan (as discussed more fully in Appendix E hereto) will be available under the Plan.

5.12 Required Distributions. Notwithstanding any other provision of the Plan, all benefits payable under the Plan shall be distributed, or commence to be distributed, in compliance with the following provisions:

(a) Required Distributions for Certain Persons Who are 70½ or Older. Unless a Participant’s or former Participant’s entire nonforfeitable interest in his Plan benefit is distributed to him in a single sum no later than his Required Beginning Date or in the form of an annuity purchased from an insurance company, the Participant’s or former Participant’s nonforfeitable interest in his Plan benefit must begin to be

V-5

distributed, not later than his Required Beginning Date, over the life of the Participant or former Participant, or the joint lives of the Participant or former Participant and his Section 401(a)(9) Beneficiary, or over a period not extending beyond the life expectancy of the Participant or former Participant or the joint and last survivor expectancy of the Participant or former Participant and his Section 401(a)(9) Beneficiary. The distribution required to be made on or before the Participant’s or former Participant’s Required Beginning Date shall be the distribution required for his first Distribution Calendar Year. The minimum required distribution for other Distribution Calendar Years, including the required minimum distribution for the Distribution Calendar Year in which the Participant’s or former Participant’s Required Beginning Date occurs must be made on or before December 31 of that Distribution Calendar Year. In the case of a benefit payable in a form other than a single sum or an annuity purchased from an insurance company, the amount that must be distributed for a Distribution Calendar Year is an amount equal to the amount specified in Paragraph (b) of this Section 5.12.

(b) Required Minimum Distributions. If a Participant’s or former Participant’s Required Beginning Date is before the date on which he incurs a Separation From Service, the Participant or former Participant (if he is then alive) must be paid either the entire amount credited to his Account or annual distributions from the Plan in the amounts required under section 401(a)(9) of the Code and Regulations thereunder commencing no later than his Required Beginning Date until his entire interest under the Plan has been distributed under this Article V. The distribution required to be made on or before the Participant’s or former Participant’s Required Beginning Date shall be the distribution required for his first Distribution Calendar Year. The minimum required distribution for other Distribution Calendar Years, including the required minimum distribution for the Distribution Calendar Year in which the Participant’s or former Participant’s Required Beginning Date occurs must be made on or before December 31 of that Distribution Calendar Year. The amount that must be distributed for a Distribution Calendar Year is an amount equal to (1) the Participant’s or former Participant’s Account balance as of the last Valuation Date in the calendar year immediately preceding the Distribution Calendar Year, increased by any contributions or forfeitures allocated and made to the Account during such immediately preceding calendar year after the Valuation Date, and decreased by distributions made during such immediately preceding calendar year after the Valuation Date, divided by (2) the Participant’s or former Participant’s Applicable Distribution Period.

(c) Distribution Deadline for Death Benefit When Participant or Former Participant Dies Before His Distributions Begin. If a Participant or former Participant dies before the date distribution of his nonforfeitable interest in his Plan benefit begins, his entire nonforfeitable interest in his Plan benefit will be distributed, or begin to be distributed, to his Section 401(a)(9) Beneficiary no later than as follows:

(1) If the Participant’s or former Participant’s surviving Spouse is the Participant’s or former Participant’s sole Section 401(a)(9) Beneficiary, then distributions to the surviving Spouse will begin by December 31 of the calendar year immediately following the calendar year in which the Participant or former

V-6

Participant died, or by December 31 of the calendar year in which the Participant or former Participant would have attained age 70 1/2 , if later.

(2) If the Participant’s or former Participant’s surviving Spouse is not the Participant’s or former Participant’s sole Section 401(a)(9) Beneficiary and the payment of Plan death benefits to the Section 401(a)(9) Beneficiary will not be in the form of a single sum or a commercial annuity, then distributions to the Section 401(a)(9) Beneficiary will begin by December 31 of the calendar year immediately following the calendar year in which the Participant or former Participant died.

(3) If the Participant’s or former Participant’s surviving Spouse is the Participant’s or former Participant’s sole Section 401(a)(9) Beneficiary, and the payment of a Plan death benefit to the Section 401(a)(9) Beneficiary will be in the form of a single sum, then the Participant’s or former Participant’s entire nonforfeitable interest in his Plan benefit will be distributed by December 31 of the calendar year containing the fifth anniversary of the Participant’s or former Participant’s death.

(4) If there is no Section 401(a)(9) Beneficiary as of September 30 of the calendar year following the calendar year of the Participant’s or former Participant’s death, then the Participant’s or former Participant’s entire nonforfeitable interest in his Plan benefit will be distributed by December 31 of the calendar year containing the fifth anniversary of the Participant’s or former Participant’s death.

(5) If the Participant’s or former Participant’s surviving Spouse is the Participant’s or former Participant’s sole Section 401(a)(9) Beneficiary and the surviving Spouse dies after the Participant or former Participant but before distributions to the surviving Spouse begin, this Section 5.12(e), other than Section 5.12(e)(1), will apply as if the surviving Spouse were the Participant.

Unless the Participant’s or former Participant’s interest is distributed in the form of an annuity or in a single sum on or before the Required Beginning Date, as of the first Distribution Calendar Year distributions will be made in accordance with Paragraph (b) of this Section 5.12.

(d) Distribution of Death Benefit When Participant or Former Participant Dies On or After His Required Beginning Date. If a Participant or former Participant dies on or after his Required Beginning Date, his Plan benefit must be distributed to his Section 401(a)(9) Beneficiary at least as rapidly as the method of payment of minimum required distributions being used as of the date of his death.

(e) Limitations on Death Benefits. Benefits payable under the Plan shall not be provided in any form that would cause a Participant’s or former Participant’s death benefit to be more than incidental. Any distribution required to satisfy the incidental

V-7

benefit requirement shall be considered a required distribution for purposes of section 401(a)(9) of the Code.

(f) Requirements in the Case of a Commercial Annuity. If a Participant’s or former Participant’s nonforfeitable interest in his Plan benefit is distributed in the form of an annuity purchased from an insurance company, distributions under the annuity contract will be made in accordance with the requirements of section 401(a)(9) of the Code and Department of Treasury Regulations.

(g) Compliance with Section 401(a)(9). All distributions under the Plan will be made in accordance with the requirements of section 401(a)(9) of the Code and all Regulations promulgated thereunder, including, effective January 1, 2003, the Final Section 401(a)(9) Regulations, including sections 1.401(a)(9)-1 through 1.401(a)(9)-9 of the Final Section 401(a)(9) Regulations. The provisions of the Plan reflecting section 401(a)(9) of the Code override any distribution options in the Plan inconsistent with section 401(a)(9) of the Code.

(h) Compliance with Section 401(a)(14). Unless the Participant or former Participant otherwise elects, the payment of benefits under the Plan to the Participant or former Participant will begin not later than the 60th day after the close of the Plan Year in which occurs the latest of (a) the date on which the Participant or former Participant attains the later of age 62 or Retirement Age, (b) the tenth anniversary of the year in which the Participant or former Participant commenced participation in the Plan, or (c) the Participant’s or former Participant’s Separation From Service.

5.13 Designation of Beneficiary. Each Participant and former Participant has the right to designate and to revoke the designation of his Beneficiary or Beneficiaries. Each designation or revocation must be evidenced by a written document in the form required by the Committee, signed by the Participant or former Participant and filed with the Committee. If no designation is on file at the time of a Participant’s or former Participant’s death or if the Committee determines that the designation is ineffective, the designated Beneficiary shall be the Participant’s or former Participant’s Spouse, if living, or if not, the executor, administrator or other personal representative of the Participant’s or former Participant’s estate. If a Participant or former Participant is considered to be married under local law, his designation of any Beneficiary, other than his Spouse, shall not be valid unless the Spouse acknowledges in writing that the Spouse understands the effect of the Participant’s or former Participant’s beneficiary designation and consents to it. The consent must be to a specific Beneficiary. The written acknowledgement and consent must be filed with the Committee, signed by the Spouse and at least two witnesses, one of whom must be a member of the Committee or a notary public. However, if the Spouse cannot be located or there exist other circumstances as described in sections 401(a)(11) and 417(a)(2) of the Code, the requirement of the Participant’s or former Participant’s Spouse’s acknowledgement and consent may be waived. If a Beneficiary other than the Participant’s or former Participant’s Spouse is named, the designation shall become invalid if the Participant or former Participant is later determined to be married under local law, the Participant’s or former Participant’s missing Spouse is located or the circumstances which resulted in the waiver of the requirement of obtaining the consent of his Spouse no longer exist.

V-8

5.14 Distributions to Minors and Incapacitated Persons. If the Committee determines that any person to whom a payment is due is a minor or is unable to care for his affairs because of physical or mental disability, it shall have the authority to cause the payments to be made to the Spouse, brother, sister or other person the Committee determines to have incurred, or to be expected to incur, expenses for that person unless a prior claim is made by a qualified guardian or other legal representative. The Committee and the Trustee shall not be responsible to oversee the application of those payments. Payments made pursuant to this power shall be a complete discharge of all liability under the Plan and the Trust and the obligations of the Employer, the Trustee, the Trust and the Committee.

5.15 Distributions Pursuant to Qualified Domestic Relations Orders. The Committee will instruct the Trustee to pay benefits in accordance with the terms of any order that has been determined, in accordance with Plan procedures, to be a Qualified Domestic Relations Order. A Qualified Domestic Relations Order may require the payment of an immediate cash lump sum to an alternate payee even if the Participant or former Participant is not then entitled to receive an immediate payment of Plan benefits.

5.16 Claims Review Procedures; Claims Appeal Procedures.

(a) Claims Review Procedures. When a benefit is due, the Claimant should submit a claim to the Committee. Under normal circumstances, the Committee will make a final decision as to a claim within 90 days after receipt of the claim. If the Committee notifies the Claimant in writing during the initial 90-day period, it may extend the period up to 180 days after the initial receipt of the claim. The written notice must indicate the circumstances necessitating the extension and the anticipated date for the final decision. If a claim is denied during the claims period, the Committee must notify the Claimant in writing, and the written notice must set forth in a manner calculated to be understood by the Claimant:

(1) the specific reason or reasons for denial;

(2) specific reference to the Plan provisions on which the denial is based;

(3) a description of any additional material or information necessary for the Claimant to perfect the claim and an explanation of why such material or information is necessary; and

(4) an explanation of the Plan claims review procedures and time limits, including a statement of the Claimant’s right to bring a civil action under section 502(a) of ERISA.

If a decision is not given to the Claimant within the claims review period, the claim is treated as if it were denied on the last day of the claims review period.

(b) Claims Appeals Procedures. If a Claimant’s claim made pursuant to Section 5.16(a) is denied and he wants a review, he must apply to the Committee in writing. That application can include any arguments, written comments, documents,

V-9

records, and other information relating to the claim for benefits. In addition, the Claimant is entitled to receive on request and free of charge reasonable access to and copies of all information relevant to the claim. For this purpose, “relevant” means information that was relied on in making the benefit determination or that was submitted, considered or generated in the course of making the determination, without regard to whether it was relied on, and information that demonstrates compliance with the Plan’s administrative procedures and safeguards for assuring and verifying that Plan provisions are applied consistently in making benefit determinations. The Committee must take into account all comments, documents, records, and other information submitted by the Claimant relating to the claim, without regard to whether the information was submitted or considered in the initial benefit determination. The Claimant may either represent himself or appoint a representative, either of whom has the right to inspect all documents pertaining to the claim and its denial. The Committee can schedule any meeting with the Claimant or his representative that it finds necessary or appropriate to complete its review.

(c) This Section 5.16 does not apply in connection with determinations as to whether a Participant or former Participant has incurred a Disability. Rather, such determinations shall be subject to the procedures specified in Section 5.17.

5.17 Disability Benefit Claims Procedure.

(a) Disability Benefit Initial Determination Procedure. In the case of a claim for Disability benefits, the Claimant should submit a claim to the office designated by the Committee to receive claims. Under normal circumstances, the Committee shall notify the Claimant of any Disability claims denial (wholly or partially) within 45 days after receipt of the claim.

The Committee retains the authority to unilaterally extend the initial 45 day Disability claims determination period by a period not to exceed an additional 30 days, if the Committee determines that such extension is necessary due to matters beyond the control of the Committee. If the initial Disability claims determination period is extended by the unilateral action of the Committee, the Committee shall, prior to the expiration of the initial 45 day Disability claims determination period, notify the Claimant in writing of the extension and of the circumstances requiring the extension of the Disability claims determination period.

If, prior to the end of the first 30-day extension, the Committee determines that, due to matters beyond the control of the Plan, a decision cannot be rendered within the extension period, the Disability claims determination period may be extended for an additional 30 days, provided the Committee, prior to the expiration of the first 30-day extension period, notifies the Claimant in writing of the circumstances requiring the extension and the date on which the Plan expects to render a decision. In the case of any notice extending the Disability claims determination period, the notice must be in writing and shall specifically explain the standards on which the entitlement to a benefit is based; the unresolved issues that prevent a determination on a claim; additional information that is needed to resolve those issues; and, if additional information is required from the

V-10

Claimant, a statement as to the amount of time the Claimant has to supply that information.

Calculation of Time Periods. The period of time within which a Disability benefit determination is required to be made shall begin on that date the claim is filed in accordance with this Section, without regard to whether all the information necessary to make the Disability benefits determination accompanies the filing. In the event the Disability claims determination period is extended due to the Claimant’s failure to submit information necessary to such determination, the Disability claims determination period shall be tolled from the date on which the notification of the extension is sent to the Claimant until the date on which the Claimant responds to the request for additional information. The Claimant shall be afforded at least 45 days from receipt of the notice of extension to provide the specified information. If the Claimant fails to supply the specified information within the 45-day period, the claim determination process shall continue and the specified information shall be deemed not to exist.

(b) Disability Claims Appeal Procedure. If a Claimant’s claim for a Disability benefit is denied (in whole or in part), he is entitled to a full and fair review of that denial. A full and fair review of a Disability benefit claim denial shall provide the Claimant with 180 days from the receipt of any adverse claim determination to appeal the denial. If the Claimant does not file an appeal within 180 days of the adverse claim determination, such denial becomes final.

Under the full and fair review, the Claimant shall be afforded an opportunity to submit written comments, documents, records, and other information relating to the claim for benefits to the reviewing fiduciary. The Claimant shall be entitled to receive upon request and free of charge reasonable access to and copies of all information relevant to the claim. For purposes of a Disability benefit claim denial, the term “relevant” shall mean information that was relied on in making the benefit determination or that was submitted, considered or generated in the course of making the determination, without regard to whether it was relied on, and information that demonstrates compliance with the Plan’s administrative procedures and safeguards for assuring and verifying that Plan provisions are applied consistently in making benefit determinations. For this purpose, the term “relevant” shall also include a statement of policy or guidance with respect to the Plan concerning the Disability benefit for the diagnoses of the Claimant, without regard to whether such advice or statement was relied upon in making the claims determination. The review of a benefit claim denial shall not afford any deference to the initial adverse claim determination.

The review of the Disability claims denial shall be conducted by the appropriate named fiduciary who is neither the named fiduciary who made the initial adverse claim determination nor subordinate to such individual.

In reviewing a denial of a claim for a Disability benefit, in which the denial was based in whole or in part on medical judgment, the appropriate named fiduciary shall consult with a health care professional who has appropriate training and experience in the field of medicine involved in the medical judgment. The health care professional

V-11

consulted upon review of an adverse benefit claim denial shall be neither the health care professional that was consulted in connection with the adverse benefit determination that is the subject of the appeal nor a subordinate of any such individual. The reviewing fiduciary shall provide the identification of the medical or vocational experts whose advice was obtained on behalf of the Plan in connection with Claimant’s Disability benefit claim denial, without regard as to whether the advice was relied upon in making the benefit determination.

The appropriate reviewing fiduciary must take into account all comments, documents, records, and other information submitted by the Claimant relating to the claim, without regard as to whether the information was submitted or considered in the initial benefit determination. The Claimant may either represent himself or appoint a representative, either of whom has the right to inspect all documents pertaining to the claim and its denial. The reviewing fiduciary can schedule any meeting with the Claimant or his representative that it finds necessary or appropriate to complete its review.

If a timely request is made, the reviewing fiduciary shall notify the Claimant of the determination upon appeal within 45 days after receipt of the request for review (without regard to whether all the information necessary to make the benefit determination accompanies the filing). The reviewing fiduciary retains the authority to unilaterally extend the initial 45-day review period by a period not to exceed an additional 45 days, if the fiduciary determines that special circumstances exist requiring additional time for reviewing the claim. If the initial review period is extended by the unilateral action of the appropriate reviewing fiduciary, the fiduciary shall, prior to the expiration of the initial 45 day review period, notify the Claimant in writing of the extension. The written notice of extension shall identify the special circumstances necessitating the extension and provide the anticipated date by which the Plan expects to render the determination on review.

Calculation of Time Periods Upon Appeal. The period of time within which a determination on a Disability claims appeal is required to be made shall begin on that date the appeal is filed in accordance with this Section, without regard to whether all the information necessary to make the Disability benefits determination accompanies the filing. In the event the Disability claims review period is extended due to the Claimant’s failure to submit information necessary to such determination, the Disability claims review period shall be tolled from the date on which the notification of the extension is sent to the Claimant until the date on which the Claimant responds to the request for additional information. The Claimant shall be afforded at least 45 days from receipt of the notice of extension to provide the requested information. If the Claimant fails to supply the requested information within the 45-day period, the claims review process shall continue and the specified information shall be deemed not to exist.

The reviewing fiduciary shall provide the Claimant with a written notice of the Plan’s benefit determination upon review. The notice shall set forth the specific reasons for its action, the Plan provisions on which its decision is based, and a statement that the Claimant is entitled to receive, upon request and free of charge, reasonable access to, and

V-12

copies of, all documents, records, and other information relevant to the Claimant’s claim for benefits, and a statement of the Claimant’s right to bring an action under section 502(a) of ERISA. The notice shall also include the following statement,

“You and the Plan may have other voluntary alternative dispute resolution options, such as mediation. One way to find out what may be available is to contact your local U.S. Department of Labor Office and your State insurance regulatory agency.”

If a decision is not given to the Claimant within the review period, the claim is treated as if it were denied on the last day of the review period.

The request for review must be filed within 90 days after the denial. If it is not, the denial becomes final. If a timely request is made, the reviewing fiduciary must make its decision, under normal circumstances, within 60 days of the receipt of the request for review. However, if the reviewing fiduciary notifies the Claimant prior to the expiration of the initial review period, it may extend the period of review up to 120 days following the initial receipt of the request for a review. The written notice must indicate the circumstances necessitating the extension and the anticipated date for the final decision. All decisions of the reviewing fiduciary must be in writing and must include the specific reasons for its action, the Plan provisions on which its decision is based, and a statement that the Claimant is entitled to receive, upon request and free of charge, reasonable access to, and copies of, all documents, records, and other information relevant to the Claimant’s claim for benefits, and a statement of the Claimant’s right to bring an action under section 502(a) of ERISA. If a decision is not given to the Claimant within the review period, the claim is treated as if it were denied on the last day of the review period.

6.01 In-Service Financial Hardship Distributions.

(a) General. Prior to his Separation From Service, a Participant is entitled to receive a distribution from his Salary Deferral Contribution Account (except for income that was not credited to his Salary Deferral Account as of December 31, 1988), his Catch-up Salary Deferral Contribution Account (except for income credited to his Catch-up Salary Deferral Contribution Account), his Rollover Account, his Nonforfeitable Interest in his Matching Contribution Account and his Nonforfeitable Interest in his Supplemental Contribution Account in the event of an immediate and heavy financial need incurred by the Participant and the Committee’s determination that the withdrawal is necessary to alleviate that hardship.

(f) Order of Distributions. Financial hardship distributions will be made in the following order: First withdrawals will be made from the Participant’s Rollover Contribution Account, then from his Matching Contribution Account, then from his Supplemental Contribution Account, then from his Salary Deferral Contribution Account, and finally, from his Catch-up Salary Deferral Contribution Account.

ARTICLE VII

LOANS

Except as specified below, the Committee may direct the Trustees to make loans to Participants (and Beneficiaries who are “parties in interest” within the meaning of ERISA) who have Nonforfeitable Interests in their Account balances. The Loan Committee established by the Committee will be responsible for administering the Plan loan program. All loans will comply with the following requirements:

(a) All loans will be made solely from the Participant’s or Beneficiary’s Account.

(b) Loans will be available on a nondiscriminatory basis to all Beneficiaries who are “parties in interest” within the meaning of ERISA, and to all Participants.

(d) The maximum amount of a loan may not exceed the lesser of (A) $50,000.00 reduced by the person’s highest outstanding loan balance from the Plan during the preceding one-year period, or (B) one-half of the person’s Nonforfeitable Interest in his Account balance under the Plan determined as of the date on which the loan is approved by the Loan Committee.

(e) Any loan from the Plan will be evidenced by a note or notes (signed by the person applying for the loan) having such maturity, bearing such rate of interest, and containing such other terms as the Loan Committee will require by uniform and nondiscriminatory rules consistent with this Article and proper lending practices.

(f) All loans will bear a reasonable rate of interest which will be established by the Loan Committee. In determining the proper rate of interest to be charged, at the time any loan is made or renewed, the Loan Committee will contact at least two of the largest banks in the geographic location in which the Participant or Beneficiary resides to determine what interest rate the banks would charge for a similar loan taking into account the collateral offered.

(g) Each loan will be fully secured by a pledge of the borrowing person’s Nonforfeitable Interest in his Account balance. No more than 50 percent of the person’s Nonforfeitable Interest in his Account balance (determined immediately after the origination of the loan) will be considered as security for any loan.

(h) The term of the loan will not be less than 18 months. Generally, the term of the loan will not be more than five years. The Loan Committee may agree to a longer term (but not more than seven years) only if such term is otherwise reasonable and the proceeds of the loan are to be used to acquire a dwelling which will be used within a reasonable time (determined at the time the loan is made) as the principal residence of the borrowing person.

VII-1

(i) The terms of each Plan loan agreement will require substantially level amortization of the loan (with payments not less frequently than quarterly) over the term of the loan. However, the level amortization requirement will not apply for a period, not longer than one year (or such longer period as may apply under the Uniformed Services Employment and Reemployment Rights Act of 1994) that an eligible borrower is on a bona fide leave of absence, either without pay from the District or at a rate of pay (after income and employment tax withholding) that is less than the amount of the installment payments required under the terms of the loan. However, the loan (including interest that accrues during the leave of absence) must be repaid by the five-year loan maturity deadline specified in paragraph (h) above (unless the loan was a home loan described in paragraph (h) above), and the amount of the installments due after the leave ends (or, if earlier, after the first anniversary of the leave or such longer period as may apply under the Uniformed Services Employment and Reemployment Rights Act of 1994) must not be less than the amount required under the terms of the original loan.

(j) A Participant’s loan agreement will require that loan repayments be made through payroll deductions.

(k) If a person fails to make a required payment within 30 days of the due date set forth in the loan agreement, the loan will be in default.

(l) If a Participant or former Participant has an outstanding loan from the Plan at the time of his Separation From Service, the outstanding loan principal balance and any accrued but unpaid interest will become immediately due in full. The Participant or former Participant will have the right to immediately pay the Trustee that amount. If the Participant or former Participant fails to repay the loan, the Trustee will foreclose on the loan and the Participant will be deemed to have received a Plan distribution of the amount foreclosed upon. The Trustee will not foreclose upon a Participant’s or former Participant’s Salary Deferral Contribution Account or Catch-up Salary Deferral Contributions Account until the Participant’s Separation From Service.

(m) If a Beneficiary defaults on his loan, the Trustee will foreclose on the loan and the Beneficiary will be deemed to have received a Plan distribution of the amount foreclosed upon.

(n) No amount that is pledged as collateral for a Plan loan to a Participant will be available for withdrawal before he has fully repaid his loan.

(o) The Spouse of a Participant must consent to any loan from the Plan that is made, extended or renewed after the date on which the Sponsor elects to treat the Plan and the Quanex Corporation Salaried Employees’ Pension Plan as one plan for purposes of section 410(b) of the Code. The Spouse’s consent must (1) be in writing, (2) consent to the loan, (3) acknowledge the effect of the Spouse’s consent to the Participant’s borrowing from the Plan, and (4) be witnessed by a notary public or a Plan representative.

A Participant or former Participant shall at all times have a fully nonforfeitable interest in amounts credited to his Salary Deferral Contribution Account, his Catch-up Salary Deferral Contribution Account, his QNEC Account, and his Rollover Account.

(b) If a Participant or former Participant neither receives nor is deemed to receive a distribution as a result of his Separation From Service, the nonvested portion of his Account balance will be permanently forfeited (with no right of reinstatement under Section 9.02) on the later of the date of his Separation From Service or the date on which he has incurred a Period of Severance of five consecutive years.

9.02 Restoration of Forfeited Amounts. If a Participant or former Participant who forfeited any portion of his Account balance pursuant to the provisions of Section 8.01 subsequently performs an Hour of Service, then the following provisions shall apply:

(a) Repayment Requirement.

A Participant who is deemed to have received a distribution under Section 5.04 (because he had no Nonforfeitable Interest in his Account balance) will be deemed to have repaid his Account balance upon his reemployment if he is reemployed before the earlier of the dates specified in clauses (1) and (2) in the preceding sentence.

(b) Amount Restored. The amount to be restored under the preceding provisions of this Section 9.02 shall be the dollar value of the Account balance, both the amount distributed and the amount forfeited. The Participant’s Account balance shall be restored as soon as administratively practicable after the later of the date the Participant first performs an Hour of Service after his Separation From Service or the date on which any required repayment is completed.

(c) No Other Basis for Restoration. Except as otherwise provided above, a Participant’s Account balance shall not be restored after it has been forfeited pursuant to Section 9.01.

9.03 Forfeitures by Lost Participants or Beneficiaries. If a person who is entitled to a distribution cannot be located during a reasonable search after the Committee has initially attempted making payment, his Account balance shall be forfeited. However, if at any time prior

For purposes of determining an Employee’s eligibility to participate in the Plan and his Nonforfeitable Interest in his Account balance, the Employee shall receive credit for Active Service commencing on the date he first performs an Hour of Service and ending on his Severance From Service Date. If such an Employee Severs Service, he shall recommence earning Active Service when he again performs an Hour of Service. If such an Employee performs an Hour of Service within twelve months after his Severance From Service Date, the intervening Period of Severance shall be counted as Active Service. When determining such an Employee’s Active Service, all Periods of Service, whether or not completed consecutively, shall be aggregated on a per-day basis. In aggregating service for purposes of determining such an Employee’s Nonforfeitable Interest in amounts credited to his Account, 365 days shall be counted as one year of Active Service. Except to the extent expressly provided otherwise in the Plan, such an Employee shall be granted credit for all Periods of Service with Affiliated Employers (including Periods of Service performed while the Employee is not eligible to participate in the Plan because he does not satisfy the requirements of Section 2.01).

10.02 Disregard of Certain Service. If such an Employee incurs a Separation From Service at a time when he does not have a Nonforfeitable Interest in a portion of his Supplemental Contribution Account balance and his Period of Severance continues for a continuous period of five years or more, the Period of Service completed by the Employee before the Period of Severance shall not be taken into account as Active Service, if his Period of Severance equals or exceeds his Period of Service, whether or not consecutive, completed before the Period of Severance.

10.03 Certain Brief Absences Counted as Active Service. If an Employee performs an Hour of Service within 365 days after he Severs Service, the intervening Period of Severance shall be counted as a Period of Service.

10.04 Special Maternity or Paternity Absence Rules. Except as specified below, the period of time between (a) the first anniversary of the first day of a Maternity or Paternity Absence of such an Employee and (b) the second anniversary of the first day of the absence shall not be counted as a Period of Severance or as Active Service. However, if the Employee returns to active employment with an Affiliated Employer prior to the expiration of twelve months following the earlier of (1) the date of his Separation From Service or (2) the second anniversary of the first day of his Maternity or Paternity Absence, he shall be granted Active Service for the entire period of his Maternity or Paternity Absence.

10.05 Employment Records Conclusive. The employment records of the Employer shall be conclusive for all determinations of Active Service.

ARTICLE XII

ADOPTION OF PLAN BY OTHER EMPLOYERS

12.01 Adoption Procedure. Any business organization may, with the approval of the Board, adopt the Plan by:

(a) a certified resolution or consent of the board of directors of the adopting Employer or an executed adoption instrument (approved by the board of directors of the adopting Employer) agreeing to be bound as an Employer by all the terms, conditions and limitations of the Plan except those, if any, specifically described in the adoption instrument; and

(b) providing all information required by the Committee and the Trustee.

12.02 No Joint Venture Implied. The document which evidences the adoption of the Plan by an Employer shall become a part of the Plan. However, neither the adoption of the Plan and the Trust by an Employer nor any act performed by it in relation to the Plan and the Trust shall ever create a joint venture or partnership relation between it and any other Employer.

12.03 All Trust Assets Available to Pay All Benefits. The Accounts of Participants employed by the Employers that adopt the Plan shall be commingled for investment purposes. All assets in the Trust shall be available to pay benefits to all Participants employed by any Employer.

12.04 Qualification a Condition Precedent to Adoption and Continued Participation. The adoption of the Plan and the Trust by a business organization is contingent upon and subject to the express condition precedent that the initial adoption meets all statutory and regulatory requirements for qualification of the Plan and the exemption of the Trust that are applicable to it and that the Plan and Trust continue in operation to maintain their qualified and exempt status. In the event the adoption fails to initially qualify, the adoption shall fail retroactively for failure to meet the condition precedent and the portion of the Trust assets applicable to the adoption shall be immediately returned to the adopting business organization and the adoption shall be void ab initio. In the event the adoption as to a given business organization later becomes disqualified and loses its exemption for any reason, the adoption shall fail retroactively for failure to meet the condition precedent and the portion of the Trust assets allocable to the adoption by that business organization shall be immediately spun off, retroactively as of the last date for which the Plan qualified, to a separate trust for its sole benefit and an identical but separate Plan shall be created, retroactively effective as of the last date the Plan as adopted by that business organization qualified, for the benefit of the Participants covered by that adoption.

ARTICLE XIII

AMENDMENT AND TERMINATION

13.01 Right to Amend and Limitations Thereon. The Sponsor has the sole right to amend the Plan. An amendment may be made by a certified resolution or consent of the Board, or by an instrument in writing executed by the appropriate officer of the Sponsor. The amendment must describe the nature of the amendment and its effective date. No amendment shall:

(a) vest in an Employer any interest in the Trust;

(b) cause or permit the Trust assets to be diverted to any purpose other than the exclusive benefit of the present, former or future Participants and their Beneficiaries except under the circumstances described in Section 3.13;

(c) decrease the Account of any Participant or former Participant, or eliminate an optional form of payment in violation of section 411(d)(6) of the Code; or

(d) change the vesting schedule to one which would result in a Participant’s or former Participant’s Nonforfeitable Interest in his Account balance (determined as of the later of the date of the adoption of the amendment or of the effective date of the amendment) of any Participant or former Participant being less than his Nonforfeitable Interest computed under the Plan without regard to the amendment. If the Plan’s vesting schedule is amended or if the Plan is deemed amended by an automatic change to or from a top-heavy vesting schedule, each Participant or former Participant who has at least three years of Active Service as of the date of the amendment or change shall have his nonforfeitable percentage computed under the Plan without regard to the amendment or the change if that results in a higher Nonforfeitable Interest in his Account balance.

Each Employer shall be deemed to have adopted any amendment made by the Sponsor unless the Employer notifies the Committee of its rejection in writing within 30 days after it receives a copy of the amendment. A rejection shall constitute a withdrawal from the Plan by that Employer unless the Sponsor acquiesces in the rejection.

13.02 Mandatory Amendments. The Contributions of each Employer to the Plan are intended to be:

(a) deductible under the applicable provisions of the Code;

(b) except as otherwise prescribed by applicable law, exempt from the Federal Social Security Act;

(d) excludable from any Employee’s regular rate of pay, as that term is defined under the Fair Labor Standards Act of 1938, as amended.

XIII-1

The Sponsor shall make any amendment necessary to carry out this intention, and it may be made retroactively.

13.03 Withdrawal of Employer. An Employer may withdraw from the Plan and the Trust if the Sponsor does not acquiesce in its rejection of an amendment or by giving written notice of its intent to withdraw to the Committee. The Committee shall then determine the portion of the Trust assets that is attributable to the Participants employed by the withdrawing Employer and shall notify the Trustee to segregate and transfer those assets to the successor trustee when it receives a designation of the successor from the withdrawing Employer.

A withdrawal shall not terminate the Plan and the Trust with respect to the withdrawing Employer, if the Employer either appoints a successor trustee and reaffirms the Plan and the Trust as its new and separate plan and trust intended to qualify under section 401(a) of the Code, or establishes another plan and trust intended to qualify under section 401(a) of the Code.

The determination of the Committee, in its sole discretion, of the portion of the Trust assets that is attributable to the Participants employed by the withdrawing Employer shall be final and binding upon all parties; and, the Trustee’s transfer of those assets to the designated successor Trustee shall relieve the Trustee of any further obligation, liability or duty to the withdrawing Employer, the Participants employed by that Employer and their Beneficiaries, and the successor trustee.

13.04 Termination of Plan. The Sponsor may terminate the Plan and the Trust with respect to all Employers by executing and delivering to the Committee and the Trustee, a notice of termination, specifying the date of termination.

13.05 Partial or Complete Termination or Complete Discontinuance of Contributions. Without regard to any other provision of the Plan, if there is a partial or total termination of the Plan or there is a complete discontinuance of the Employer’s Contributions, each of the affected Participants shall immediately have a fully Nonforfeitable Interest in his Account as of the end of the last Plan Year for which a substantial Employer Contribution was made and in any amounts later allocated to his Account.

MISCELLANEOUS

14.01 Plan Not an Employment Contract. The maintenance of the Plan and the Trust is not a contract between any Employer and its Employees which gives any Employee the right to be retained in its employment.

Further, effective for judgments, orders and decrees issued, and settlement agreements entered into, on or after August 5, 1997, these prohibitions shall not apply to any offset of a Participant’s or former Participant’s benefits provided under a Plan against an amount that the Participant or former Participant is ordered or required to pay to the Plan if—(a) the order or requirement to pay arises—(1) under a judgment of conviction for a crime involving the Plan, (2) under a civil judgment (including a consent order or decree) entered by a court in an action brought in connection with an alleged violation of part 4 of subtitle B of title I of ERISA, or (3) pursuant to a settlement agreement between the Secretary of Labor and the Participant or former Participant in connection with a violation (or alleged violation) of part 4 of subtitle B of ERISA by a fiduciary or any other person, and (b) the judgment, order, decree, or settlement agreement expressly provides for the offset of all or part of the amount ordered or required to be paid to the Plan against the Participant’s or former Participant’s benefits provided under the Plan.

A.1.1 “Actual Contribution Ratio” shall mean the ratio of Section 401(m) Contributions actually paid into the Trust on behalf of an Employee for a Plan Year to the Employee’s Annual Compensation for the same Plan Year. For this purpose, Annual Compensation for any portion of the Plan Year in which the Employee was not an eligible Employee (as defined in Section A.2.4) will not be taken into account.

A.1.2 “Actual Deferral Percentage” means, for a specified group of Employees for a Plan Year, the average of the ratios (calculated separately for each Employee in the group) of the amount of Section 401(k) Contributions actually paid into the Trust on behalf of the Employee for the Plan Year to the Employee’s Annual Compensation for the Plan Year.

A.1.3 “Actual Deferral Ratio” means the ratio of Section 401(k) Contributions actually paid into the Trust on behalf of an Employee for a Plan Year to the Employee’s Annual Compensation for the same Plan Year. For this purpose, Annual Compensation for any portion of the Plan Year in which the Employee was not an eligible Employee (as defined in Section A.2.3) will not be taken into account.

A.1.4 “Annual Additions” means the sum of the following amounts credited on behalf of a Participant for the Limitation Year: (a) Employer contributions excluding Catch-up Salary Deferral Contributions and including Salary Deferral Contributions, (b) Employee after-tax contributions, and (c) forfeitures. For this purpose, Employee contributions are determined without regard to any rollover contributions (as defined in sections 402(c), 403(a)(4), 403(b)(8), 408(d)(3) and 457(e)(16) of the Code without regard to employee contributions to a simplified employee pension which are excludable from gross income under section 408(k)(6) of the Code). Excess 401(k) Contributions for a Plan Year are treated as Annual Additions for that Plan Year even if they are corrected through distribution. Excess Deferrals that are timely distributed as set forth in Section A.3.1 will not be treated as Annual Additions.

A.1.5 “Contribution Percentage” shall mean, for a specified group of Employees for a Plan Year, the average of the ratios (calculated separately for each Employee in the group) of the amount of Section 401(m) Contributions actually paid into the Trust on behalf of the Employee for the Plan Year to the Employee’s Annual Compensation for the Plan Year.

A.1.6 “Excess Aggregate 401(m) Contributions” means, with respect to any Plan Year, the excess of (a) the aggregate amount of Section 401(m) Contributions actually paid into the Trust on behalf of Highly Compensated Employees for the Plan Year over (b) the maximum amount of those contributions permitted under the limitations set out in the first sentence of Section A.2.4.

A.1.7 “Excess Amount” shall mean the excess of the Annual Additions credited to the Participant’s Account for the Limitation Year over the Maximum Permissible Amount.

A.1.8 “Excess 401(k) Contributions” means, with respect to any Plan Year, the excess of (a) the aggregate amount of Section 401(k) Contributions actually paid to the Trustee on behalf of Highly Compensated Employees for the Plan Year over (b) the maximum amount of those contributions permitted under the limitations set out in the first sentence of Section A.2.3.A or Section A.2.3.B as applicable.

A.1.9 “Limitation Year” shall mean the Plan Year. All qualified plans maintained by any Affiliated Employer must use the same Limitation Year. If the Limitation Year is amended to a different 12-consecutive

A-1

month period, the new Limitation Year must begin on a date within the Limitation Year in which the amendment is made.

A.1.10 “Maximum Permissible Amount” means, for Limitation Years that commence prior to January 1, 2002, the lesser of (1) $30,000.00 as adjusted by the Secretary of Treasury for increases in the cost of living, or (2) 25 percent of the Participant’s Annual Compensation for the Limitation Year. “Maximum Permissible Amount” means, for Limitation Years that commence on or after January 1, 2001, the lesser of (1) $40,000.00 as adjusted by the Secretary of Treasury for increases in the cost of living or (2) 100 percent of the Participant’s Annual Compensation for the Limitation Year. The Annual Compensation limitation referred to in clauses (2) of the immediately preceding sentences shall not apply to any contribution for medical benefits (within the meaning of section 401(h) or section 419A(f)(2) of the Code) that is otherwise treated as an Annual Addition under section 415(l)(1) or section 419A(d)(2) of the Code. If a short Limitation Year is created because of an amendment changing the Limitation Year to a different 12-consecutive month period, the Maximum Permissible Amount shall not exceed the dollar limitation in effect under section 415(c)(1)(A) of the Code multiplied by a fraction, the numerator of which is the number of months in the short Limitation Year, and the denominator of which is 12.

A.1.11 “Section 401(k) Contributions” means the sum of Salary Deferral Contributions made on behalf of the Participant during the Plan Year, and QNECs that the Employer elects to have treated as section 401(k) Contributions pursuant to section 401(k)(3)(d)(ii) of the Code.

A.1.12 “Section 401(m) Contributions” shall mean the Matching Contributions made on behalf of the Participant during the Plan Year and other amounts that the Employer elects to have treated as Section 401(m) Contributions pursuant to section 401(m)(3)(B) of the Code. However, effective for Plan Years that commence prior to January 1, 2002, Matching Contributions and Salary Deferral Contributions that the Employer could otherwise elect to have treated as Section 401(m) Contributions are not Section 401(m) Contributions to the extent that they are used to enable the Plan to satisfy the minimum contribution requirements of section 416 of the Code.

PART A.2 Limitations on Contributions

A.2.1 Limitations Based upon Deductibility and the Maximum Allocation Permitted to a Participant’s Account. Notwithstanding any other provision of the Plan, no Employer shall make any contribution that would be a nondeductible contribution within the meaning of section 4972 of the Code or that would cause the limitation on allocations to each Participant’s Account under section 415 of the Code and Section A.4.1 to be exceeded.

A.2.2 Dollar Limitation upon Salary Deferral Contributions. The maximum Salary Deferral Contribution that a Participant may elect to have made on his behalf during a calendar year may not, when added to his elective deferrals under other plans or arrangements which are both (1) described in sections 401(k), 403(b), 408(k) and 408(p)(2) of the Code and (2) maintained by the Employer or an Affiliated Employer, exceed the amount of the limitation in effect under section 402(g)(1) of the Code for the Participant’s taxable year beginning in such calendar year. For purposes of applying the requirements of Section A.2.3, Excess Deferrals shall not be disregarded merely because they are Excess Deferrals or because they are distributed in accordance with this Section. However, Excess Deferrals made to the Plan on behalf of Non-Highly Compensated Employees are not to be taken into account under Section A.2.3.

A.2.3.A. Limitation Based upon Actual Deferral Percentage for Employees Other Than Certain Persons Working In Lincolnshire, Illinois. The following rules of this Section A.2.3.A are applicable for Employees other than Employees who are working in Lincolnshire, Illinois and are included in a unit of employees covered by a collective bargaining agreement between the Sponsor and the employees’ representative. Effective for Plan Years commencing on or after January 1, 1997, the Actual Deferral Percentage for eligible Highly Compensated Employees for any Plan Year must bear a relationship to the Actual Deferral Percentage for all other eligible Employees for (1) the preceding Plan Year in the case of testing for the 1997 Plan Year and Plan Years commencing on or after January 1, 2001, or (2) the current Plan Year in the case of testing for Plan Years commencing prior to January 1, 2001, other than the 1997 Plan Year, which meets either of the following tests:

A-2

(a) the Actual Deferral Percentage of the eligible Highly Compensated Employees is not more than the Actual Deferral Percentage of all other eligible Employees multiplied by 1.25; or

(b) the excess of the Actual Deferral Percentage of the eligible Highly Compensated Employees over that of all other eligible Employees is not more than two percentage points, and the Actual Deferral Percentage of the eligible Highly Compensated Employees is not more than the Actual Deferral Percentage of all other eligible Employees multiplied by two.

For purposes of this test an eligible Employee is an Employee who is directly or indirectly eligible to make Salary Deferral Contributions for all or part of the Plan Year. A person who is suspended from making Salary Deferral Contributions because he has made a withdrawal is an eligible Employee. If no Salary Deferral Contributions are made for an eligible Employee, the Actual Deferral Ratio that shall be included for him in determining the Actual Deferral Percentage is zero. If the Plan and any other plan or plans which include cash or deferred arrangements are considered as one plan for purposes of section 401(a)(4) or 410(b) of the Code, the cash or deferred arrangements included in the Plan and the other plans shall be treated as one plan for purposes of this Section. If any Participant who is a Highly Compensated Employee is a participant in any other cash or deferred arrangements of the Employer, when determining the deferral percentage of such Participant, all such cash or deferred arrangements are treated as one plan for these dates.

Notwithstanding the foregoing, effective for Plan Years commencing on or after January 1, 1998, an individual who is not a Highly Compensated Employee and who has not satisfied the minimum age and service requirements of section 410(a)(1)(A) of the Code will not be treated as an eligible Employee for purposes of this Section A.2.3.A if the Sponsor elects to apply section 410(b)(4)(3) of the Code in determining whether the Plan meets the requirements of section 401(k)(3) of the Code.

A Salary Deferral Contribution will be taken into account under the Actual Deferral Percentage test of section 401(k) of the Code and this Section for a Plan Year only if it relates to Considered Compensation that either would have been received by the Employee in the Plan Year (but for the deferral election) or is attributable to services performed by the Employee in the Plan Year and would have been received by the Employee within 2½ months after the close of the Plan Year (but for the deferral election). In addition, a Section 401(k) Contribution will be taken into account under the Actual Deferral Percentage test of section 401(k) of the Code and this Section for a Plan Year only if it is allocated to an Employee as of a date within that Plan Year. For this purpose a Section 401(k) Contribution is considered allocated as of a date within a Plan Year if the allocation is not contingent on participation or performance of services after such date and the Section 401(k) Contribution is actually paid to the Trust no later than 12 months after the Plan Year to which the Section 401(k) Contribution relates.

Failure to correct Excess 401(k) Contributions by the close of the Plan Year following the Plan Year for which they were made will cause the Plan’s cash or deferred arrangement to be disqualified for the Plan Year for which the Excess 401(k) Contributions were made and for all subsequent years during which they remain in the Trust. Also, the Employer will be liable for a ten percent excise tax on the amount of Excess 401(k) Contributions unless they are corrected within 2½ months after the close of the Plan Year for which they were made.

For the Plan Year that commences on January 1, 2001, the Actual Deferral Percentage of persons who are not Highly Compensated Employees will be determined by taking into account only (1) Salary Deferral Contributions for such persons that were taken into account for purposes of the actual deferral percentage test set forth in section 401(k) of the Code and this Section A.2.3.A for the Plan Year that commenced on January 1, 2000 and (2) QNECS that were allocated to the Accounts of such persons for the Plan Year that commenced on January 1, 2000 but that were not used to satisfy the actual deferral percentage test set forth in section 401(k) of the Code and this Section A.2.3.A or the actual contribution percentage test set forth in section 401(m) of the Code and Section A.2.4 for the Plan Year that commenced on January 1, 2000.

A.2.3.B. Limitation Based upon Actual Deferral Percentage for Certain Employees Working In Lincolnshire, Illinois. The following rules of this Section A.2.3.B are applicable for Employees other than Employees who are working in Lincolnshire, Illinois and are included in a unit of employees covered by a collective bargaining agreement between the Sponsor and the employees’ representative. Effective for Plan Years

A-3

commencing on or after January 1, 1997, the Actual Deferral Percentage for eligible Highly Compensated Employees for any Plan Year must bear a relationship to the Actual Deferral Percentage for all other eligible Employees for the preceding Plan Year, which meets either of the following tests:

(c) the Actual Deferral Percentage of the eligible Highly Compensated Employees is not more than the Actual Deferral Percentage of all other eligible Employees multiplied by 1.25; or

(d) the excess of the Actual Deferral Percentage of the eligible Highly Compensated Employees over that of all other eligible Employees is not more than two percentage points, and the Actual Deferral Percentage of the eligible Highly Compensated Employees is not more than the Actual Deferral Percentage of all other eligible Employees multiplied by two.

Notwithstanding the foregoing, effective for Plan Years commencing on or after January 1, 1998, an individual who is not a Highly Compensated Employee and who has not satisfied the minimum age and service requirements of section 410(a)(1)(A) of the Code will not be treated as an eligible Employee for purposes of this Section A.2.3.B if the Sponsor elects to apply section 410(b)(4)(3) of the Code in determining whether the Plan meets the requirements of section 401(k)(3) of the Code.

For the Plan Year that commences on January 1, 1997, the Actual Deferral Percentage of persons who are not Highly Compensated Employees will be determined by taking into account only (1) Salary Deferral Contributions for such persons that were taken into account for purposes of the actual deferral percentage test set forth in section 401(k) of the Code and this Section A.2.3.A for the Plan Year that commenced on January 1, 1996 and (2) QNECS that were allocated to the Accounts of such persons for the Plan Year that commenced on January 1, 1996 but that were not used to satisfy the actual deferral percentage test set forth in section 401(k) of the Code and this Section A.2.3.B.

A-4

A.2.4 Limitation Based upon Contribution Percentage. The following rules are applicable for Employees other than Employees who are working in Lincolnshire, Illinois and are included in a unit of employees covered by a collective bargaining agreement between the Sponsor and the employees’ representative. Effective for Plan Years commencing on or after January 1, 1997, the Contribution Percentage for eligible Highly Compensated Employees for any Plan Year must bear a relationship to the Actual Contribution Percentage for all other eligible Employees for (1) the preceding Plan Year in the case of testing for Plan Years commencing on or after January 1, 2001, or (2) the current Plan Year in the case of testing for Plan Years commencing prior to January 1, 2001, which meets either of the following tests:

(e) the Contribution Percentage for all other eligible Employees multiplied by 1.25; or

(f) the lesser of the Contribution Percentage for all other eligible Employees multiplied by two, or the Contribution Percentage for all other eligible Employees plus two percentage points.

For purposes of this test an eligible Employee is an Employee who is directly or indirectly eligible to receive an allocation of Matching Contributions for all or part of the Plan Year. Except as provided below, an Employee who would be eligible to receive an allocation of Matching Contributions but for his election not to participate is an eligible Employee. An Employee who would be eligible to receive an allocation of Matching Contributions but for the limitations on his Annual Additions imposed by section 415 of the Code is an eligible Employee.

Notwithstanding the foregoing, effective for Plan Years commencing on or after January 1, 1998, an individual who is not a Highly Compensated Employee and who has not satisfied the minimum age and service requirements of section 410(a)(1)(A) of the Code will not be treated as an eligible Employee for purposes of this Section A.2.4 if the Sponsor elects to apply section 410(b)(4)(B) of the Code in determining whether the Plan meets the requirements of section 401(m)(2) of the Code.

If no Section 401(m) Contributions are made on behalf of an eligible Employee the Actual Contribution Ratio that shall be included for him in determining the Contribution Percentage is zero. If the Plan and any other plan or plans to which Section 401(m) Contributions are made are considered as one plan for purposes of section 401(a)(4) or 410(b) of the Code, the Plan and those plans are to be treated as one. The Actual Contribution Ratio of a Highly Compensated Employee who is eligible to participate in more than one plan of an Affiliated employer to which employee or matching contributions are made is calculated by treating all the plans in which the Employee is eligible to participate as one plan. However, plans that are not permitted to be aggregated under Regulation section 1.410(m)-1(b)(3)(ii) are not aggregated for this purpose.

A Matching Contribution will be taken into account under this Section for a Plan Year only if (1) it is allocated to the Employee’s Account as of a date within the Plan Year, (2) it is paid to the Trust no later than the end of the 12-month period beginning after the close of the Plan Year, and (3) it is made on behalf of an Employee on account of his Salary Deferral Contributions for the Plan Year.

At the election of the Employer, a Participant’s Salary Deferral Contributions, and QNECs made on behalf of the Participant during the Plan Year shall be treated as Section 401(m) Contributions that are Matching Contributions provided that the conditions set forth in Regulation section 1.401(m)-1(b)(5) are satisfied. Salary Deferral Contributions may not be treated as Matching Contributions for purposes of the contribution percentage test set forth in this Section unless such contributions, including those taken into account for purposes of the test set forth in this Section, satisfy the actual deferral percentage test set forth in Section A.2.3. Moreover, Salary Deferral Contributions and QNECs may not be taken into account for purposes of the test set forth in this Section to the extent that such contributions are taken into account in determining whether any other contributions satisfy the actual deferral percentage test set forth in Section A.2.3. Finally, Salary Deferral Contributions and QNECs may be taken into account for purposes of the test set forth in this Section only if they are allocated to the Employee’s Account as of a date within the Plan Year being tested within the meaning of Regulation section 1.401(k)-1(b)(4).

Failure to correct Excess Aggregate 401(m) Contributions by the close of the Plan Year following the Plan Year for which they were made will cause the Plan to fail to be qualified for the Plan Year for which the Excess

A-5

Aggregate 401(m) Contributions were made and for all subsequent years during which they remain in the Trust. Also, the Employer will be liable for a ten percent excise tax on the amount of Excess Aggregate 401(m) Contributions unless they are corrected within 2½ months after the close of the Plan Year for which they were made.

For the Plan Year that commences on January 1, 2001, the Contribution Percentage of persons who are not Highly Compensated Employees will be determined by taking into account only Matching Contributions made on behalf of such persons that were taken into account for purposes of the actual contribution percentage test set forth in section 401(m) of the Code and this Section A.2.4 for the Plan Year that commenced on January 1, 2000 and QNECS that were allocated to the Accounts of such persons for the Plan Year that commenced on January 1, 2000 but that were not used to satisfy the actual deferral percentage test set forth in section 401(k) of the Code and Section A.2.3 or the actual contribution percentage that set forth in section 401(m) of the Code and this Section A.2.4 for the Plan Year that commenced on January 1, 2000.

A.2.5 Additional Test in the Event of Multiple Use of the Alternative Limitation. Effective for Plan Years that commence prior to January 1, 2002, if the second alternative permitted in Sections A.2.3 and A.2.4 is used for both the actual deferral percentage test and the contribution percentage test the following additional limitation on Salary Deferral Contributions shall apply. The Actual Deferral Percentage plus the Contribution Percentage of the eligible Highly Compensated Employees cannot exceed the greater of (a) or (b), where

(g) is the sum of:

(i) 1.25 times the greater of the Actual Deferral Percentage or the Contribution Percentage of the eligible Non-Highly Compensated Employees for the preceding Plan Year, and

(ii) the lesser of (x) two percentage points plus the lesser of the Actual Deferral Percentage or the Contribution Percentage of the eligible Non-Highly Compensated Employees for the preceding Plan Year or (y) two times the lesser of the Actual Deferral Percentage or the Contribution Percentage of the group of eligible Non-Highly Compensated Employees for the preceding Plan Year; and

(h) is the sum of:

(i) 1.25 times the lesser of the Actual Deferral Percentage or the Contribution Percentage of the eligible Non-Highly Compensated Employees for the preceding Plan Year, and

(ii) the lesser of (x) two percentage points plus the greater of the Actual Deferral Percentage or the Contribution Percentage of the eligible Non-Highly Compensated Employees for the preceding Plan Year or (y) two times the greater of the Actual Deferral Percentage or the Contribution Percentage of the group of eligible Non-Highly Compensated Employees for the preceding Plan Year.

Notwithstanding the foregoing, the references in this Section A.2.5 to “the preceding Plan Year” shall be deemed to be references to “the current Plan Year” in the case of testing for Plan Years commencing prior to January 1, 2001.

PART A.3 Correction Procedures For Erroneous Contributions

A.3.1 Excess Deferral Fail Safe Provision. As soon as practical after the close of each Plan Year, the Committee shall determine if there would be any Excess Deferrals. If there would be an Excess Deferral by a Participant, the Excess Deferral as adjusted by any earnings or losses, will be distributed to the Participant no later than April 15 following the Participant’s taxable year in which the Excess Deferral was made. The income allocable to the Excess Deferrals for the taxable year of the Participant shall be determined by multiplying the income for the taxable year of the Participant allocable to Salary Deferral Contributions by a fraction. The numerator of the fraction is the amount of the Excess Deferrals made on behalf of the Participant for the taxable year. The

A-6

denominator of the fraction is the Participant’s total Salary Deferral Account balance as of the beginning of the taxable year plus the Participant’s Salary Deferral Contributions for the taxable year.

A.3.2 Actual Deferral Percentage Fail Safe Provision. As soon as practicable after the close of each Plan Year, the Committee shall determine whether the Actual Deferral Percentage for the Highly Compensated Employees would exceed the limitation set forth in Section A.2.3. If the limitation would be exceeded for a Plan Year, before the close of the following Plan Year (a) the amount of Excess 401(k) Contributions for that Plan Year (and any income allocable to those contributions as calculated in the specific manner required by Section A.3.5) shall be distributed or (b) the Employer may make a QNEC which it elects to have treated as a Section 401(k) Contribution. However, in the case of testing for any Plan Year that commences on or after January 1, 2001, a QNEC shall not be taken into account for purposes of the test set forth in section 401(k) of the Code and Section A.2.3 for such Plan Year unless it is made and allocated by the close of such Plan Year.

The amount of Excess 401(k) Contributions to be distributed shall be determined in the following manner:

First, the Plan will determine how much the Actual Deferral Ratio of the Highly Compensated Employee with the highest Actual Deferral Ratio would have to be reduced to satisfy the Actual Deferral Percentage Test or cause such Actual Deferral Ratio to equal the Actual Deferral Ratio of the Highly Compensated Employee with the next highest Actual Deferral Ratio. If a lesser reduction would enable the Plan to satisfy the Actual Deferral Percentage Test, only this lesser reduction may be made. Second, this process is repeated until the Actual Deferral Percentage Test is satisfied. The amount of Excess 401(k) Contributions is equal to the sum of these hypothetical reductions multiplied, in each case, by the Highly Compensated Employee’s Annual Compensation.

Then, effective for Plan Years that commence on or after January 1, 1997, the total amount of Excess 401(k) Contributions shall be distributed on the basis of the respective amounts attributable to each Highly Compensated Employee. The Highly Compensated Employees subject to the actual distribution are determined using the “dollar leveling method.” The Salary Deferral Contributions of the Highly Compensated Employee with the greatest dollar amount of Salary Deferral Contributions and other contributions treated as Section 401(k) Contributions for the Plan Year are reduced by the amount required to cause that Highly Compensated Employee’s Salary Deferral Contributions to equal the dollar amount of the Salary Deferral Contributions and other contributions treated as Section 401(k) Contributions for the Plan Year of the Highly Compensated Employee with the next highest dollar amount. This amount is then distributed to the Highly Compensated Employee with the highest dollar amount. However, if a lesser reduction, when added to the total dollar amount already distributed under this Section A.3.2, would equal the total Excess 401(k) Contributions, the lesser reduction amount shall be distributed. This process shall be continued until the amount of the Excess 401(k) Contributions have been distributed.

QNECs will be treated as Section 401(k) Contributions only if: (a) the conditions described in Regulation section 1.401(k)-1(b)(5) are satisfied and (b) they are allocated to Participants’ Accounts as of a date within that Plan Year and are actually paid to the Trust no later than the end of the 12-month period immediately following the Plan Year to which the contributions relate. If the Employer makes a QNEC that it elects to have treated as a Section 401(k) Contribution, the Contribution will be in an amount necessary to satisfy the Actual Deferral Percentage test and will be allocated first to those Non-Highly Compensated Employees who had the lowest Actual Deferral Ratio.

Any distributions of the Excess 401(k) Contributions for any Plan Year are to be made to Highly Compensated Employees on the basis of the amount of contributions by, or on behalf of, each Highly Compensated Employee. The amount of Excess 401(k) Contributions to be distributed for any Plan Year must be reduced by any excess Salary Deferral Contributions previously distributed for the taxable year ending in the same Plan Year. To the extent that Excess Section 401(k) Contributions are distributed pursuant to this Section A.3.2, the Matching Contributions made with respect to those Excess Section 401(k) Contributions shall be forfeited.

A.3.3 Contribution Percentage Fail Safe Provision. If the limitation set forth in Section A.2.4 would be exceeded for any Plan Year any one or more of the following corrective action shall be taken before the close of the following Plan Year as determined by the Committee in its sole discretion: (a) the amount of the Excess

A-7

Aggregate 401(m) Contributions for that Plan Year (and any income allocable to those Contributions as calculated in the manner set forth in Section A.3.5) shall be forfeited or (b) the Employer may make a QNEC which it elects to have treated as a Section 401(m) Contribution. However, in the case of testing for any Plan Year that commences on or after January 1, 2001, a QNEC shall not be taken into account for purposes of the test set forth in section 401(m) of the Code and Section A.2.4 for such Plan Year unless it is made and allocated by the close of such Plan Year.

The amount of Excess Aggregate 401(m) Contributions to be distributed shall be determined in the following manner:

First, the Plan will determine how much the Actual Contribution Ratio of the Highly Compensated Employee with the highest Actual Contribution Ratio would have to be reduced to satisfy the Actual Contribution Percentage Test or cause such Actual Contribution Ratio to equal the Actual Contribution Ratio of the Highly Compensated Employee with the next highest Actual Contribution Ratio. If a lesser reduction would enable the Plan to satisfy the Actual Contribution Percentage Test, only this lesser reduction may be made. Second, this process is repeated until the Actual Contribution Test is satisfied. The amount of Excess Aggregate 401(m) Contributions is equal to the sum of these hypothetical reductions multiplied, in each case, by the Highly Compensated Employee’s Annual Compensation.

Then, effective for the Plan Years that commence on or after January 1, 1997, the total amount of Excess Aggregate 401(m) Contributions shall be forfeited on the basis of the respective amounts attributable to each Highly Compensated Employee. The Highly Compensated Employees subject to the forfeitures are determined using the “dollar leveling method.” The Matching Contributions of the Highly Compensated Employee with the greatest dollar amount of Matching Contributions and other contributions treated as matching contributions for the Plan Year are reduced by the amount required to cause that Highly Compensated Employee’s Matching Contributions and other contributions treated as Section 401(m) Contributions for the Plan Year to equal the dollar amount of the Matching Contributions and other contributions treated as Section 401(m) Contributions for the Plan Year of the Highly Compensated Employee with the next highest dollar amount. This amount is then forfeited from the Account of the Highly Compensated Employee with the highest dollar amount. However, if a lesser reduction, when added to the total dollar amount already forfeited under this Section A.3.3, would equal the total Excess Aggregate 401(m) Contributions, the lesser reduction amount shall be forfeited. This process shall be continued until the amount of the Excess Aggregate 401(m) Contributions have been forfeited.

A.3.4 Alternative Limitation Fail Safe. As soon as practicable after the close of each Plan Year, the Committee shall determine whether the alternative limitation would be exceeded. If the limitation would be exceeded for any Plan Year, before the close of the following Plan Year the Actual Deferral Percentage or Contribution Percentage of the eligible Highly Compensated Employees, or a combination of both, shall be reduced by distributions made in the manner described in the Regulations. These distributions shall be in addition to and not in lieu of distributions required for Excess 401(k) Contributions and Excess Aggregate 401(m) Contributions.

A.3.5 Income Allocable to Excess 401(k) Contributions and Excess Aggregate 401(m) Contributions. The income allocable to Excess 401(k) Contributions for the Plan Year shall be determined by multiplying the income for the Plan Year allocable to Section 401(k) Contributions by a fraction. The numerator of the fraction shall be the amount of Excess 401(k) Contributions made on behalf of the Participant for the Plan Year. The denominator of the fraction shall be the Participant’s total Account balance attributable to Section 401(k) Contributions as of the beginning of the Plan Year plus the Participant’s Section 401(k) Contributions for the Plan Year. The income allocable to Excess Aggregate 401(m) Contributions for a Plan Year shall be determined by multiplying the income for the Plan Year allocable to Section 401(m) Contributions by a fraction. The numerator of the fraction shall be the amount of Excess Aggregate 401(m) Contributions made on behalf of the Participant for the Plan Year. The denominator of the fraction shall be the Participant’s total Account balance attributable to Section 401(m) Contributions as of the beginning of the Plan Year plus the Participant’s Section 401(m) Contributions for the Plan Year.

A-8

PART A.4 Limitation on Allocations

A.4.1 Basic Limitation on Allocations. The Annual Additions which may be credited to a Participant’s Accounts under the Plan for any Limitation Year will not exceed the Maximum Permissible Amount reduced by the Annual Additions credited to a Participant’s Account for the same Limitation Year under any other qualified defined contribution plans maintained by any Affiliated Employer. If the Annual Additions with respect to the Participant under such other qualified defined contribution plans are less than the Maximum Permissible Amount and the Employer Contribution that would otherwise be contributed or allocated to the Participant’s Accounts under the Plan would cause the Annual Additions for the Limitation Year to exceed this limitation, the amount contributed or allocated under the Plan will be reduced so that the Annual Additions under all qualified defined contribution plans maintained by any Affiliated Employer for the Limitation Year will equal the Maximum Permissible Amount. If the Annual Additions with respect to the Participant under such other qualified defined contribution plans maintained by any Affiliated Employer in the aggregate are equal to or greater than the Maximum Permissible Amount, no amount will be contributed or allocated to the Participant’s Account under the Plan for the Limitation Year. Effective as of January 1, 1987, until January 1, 2000 (the effective date of the repeal of section 415(e) of the Code) a permanent adjustment shall be made to the defined contribution fraction for purposes of applying the limitation of section 415(e) of the Code to the Plan. The adjustment is to permanently subtract from the defined contribution numerator an amount equal to the product of (1) the sum of the defined contribution fraction plus the defined benefit fraction as of the determination date minus one, times (2) the denominator of the defined contribution fraction as of the determination date. For this purpose, the determination date is December 31, 1986. Both fractions in clauses (1) and (2) above are computed in accordance with section 415 of the Code as amended by the Tax Reform Act of 1986 and section 1106(i)(3) of the Tax Reform Act of 1986.

A.4.2 Estimation of Maximum Permissible Amount. Prior to determining the Participant’s actual Annual Compensation for the Limitation Year, the Employer may determine the Maximum Permissible Amount on the basis of a reasonable estimation of the Participant’s Annual Compensation for such Limitation Year, uniformly determined for all Participants similarly situated. As soon as is administratively feasible after the end of the Limitation Year, the Maximum Permissible Amount for the Limitation Year shall be determined on the basis of the Participant’s actual Annual Compensation for such Limitation Year.

A.4.3 Attribution of Excess Amounts. If a Participant’s Annual Additions under the Plan and all other qualified defined contribution plans maintained by any Affiliated Employer result in an Excess Amount, the total Excess Amount shall be attributed to the Plan.

A.4.4 Treatment of Excess Amounts. If an Excess Amount attributed to the Plan is held or contributed as a result of or because of (i) the allocation of forfeitures, (ii) reasonable error in estimating a Participant’s Considered Compensation, (iii) reasonable error in calculating the maximum Salary Deferral Contribution that may be made with respect to a Participant under section 415 of the Code or (iv) any other facts and circumstances which the Commissioner of Internal Revenue finds to be justified, the Excess Amount shall be reduced as follows:

(a) First, the Excess Amount shall be reduced to the extent necessary by distributing to the Participant all Salary Deferral Contributions together with their earnings. These distributed amounts are disregarded for purposes of the testing and limitations contained in this Appendix A.

(b) Second, if the Participant is still employed by the Employer at the end of the Limitation Year, then such Excess Amounts shall not be distributed to the Participant, but shall be reallocated to a suspense account and shall be reapplied to reduce future Employer Contributions (including any allocation of forfeitures) under the Plan for such Participant in the next Limitation Year, and for each succeeding Limitation Year, if necessary.

(c) If, after application of paragraph (b) of this Section, an Excess Amount still exists, and the Participant is not still employed by the Employer at the end of the Limitation Year, then such Excess Amounts in the Participant’s Accounts shall not be distributed to the Participant, but shall be reallocated to a suspense account and shall be reapplied to reduce future Employer Contributions (including allocation of

APPENDIX B

TOP-HEAVY REQUIREMENTS

PART B.1 Definitions

Definitions. As used herein, the following words and phrases have the meaning attributed to them below:

B.1.1 “Aggregate Accounts” means the total of all account balances.

B.1.2 “Aggregation Group” means (a) each plan of the Employer or any Affiliated Employer in which a Key Employee is a Participant and (b) each other plan of the Employer or any Affiliated Employer which enables any plan in (a) to meet the requirements of either section 401(a)(4) or 410 of the Code. Any Employer may treat a plan not required to be included in the Aggregation Group as being a part of the group if the group would continue to meet the requirements of section 401(a)(4) and 410 of the Code with that plan being taken into account.

B.1.3 “Determination Date” means for a given Plan Year the last day of the preceding Plan Year or in the case of the first Plan Year the last day of that Plan Year.

B.1.4 “Key Employee” means, for Plan Years commencing prior to January 1, 2002, an Employee or former Employee (including a deceased Employee) or Beneficiary of an Employee who at any time during the Plan Year or any of the four preceding Plan Years is (a) an officer of an Employer or any Affiliated Employer having Annual Compensation greater than 50 percent of the annual addition limitation of section 415(b)(1)(A) of the Code for the Plan Year, (b) one of the ten employees having Annual Compensation from an Employer or any Affiliated Employer of greater than 100 percent of the annual addition limitation of section 415(c)(1)(A) of the Code for the Plan Year and owning or considered as owning (within the meaning of section 318 of the Code) the largest interest in an Employer or any Affiliated Employer, treated separately, (c) a Five Percent Owner of an Employer or any Affiliated Employer, treated separately, or (d) a one percent owner of an Employer or any Affiliated Employer, treated separately, having Annual Compensation from an Employer or any Affiliated Employer of more than $150,000.00. For this purpose no more than 50 employees or, if lesser, the greater of three employees or ten percent of the employees shall be treated as officers. Section 416(i) of the Code shall be used to determine percentage of ownership. For the purpose of the test set out in (b) above, if two or more employees have the same interest in an Employer, the employee with the greater Annual Compensation from the Employer shall be treated as having the larger interest.

“Key Employee” means for Plan Years commencing on or after January 1, 2002, an Employee or former Employee (including a deceased Employee) who at any time during the Plan Year is (a) an officer of any Affiliated Employer having Annual Compensation greater than $130,000.00 (as adjusted by the Secretary of Treasury from time to time for increases in the cost of living), (b) a Five Percent Owner of any Affiliated Employer, treated separately, or (c) a One Percent Owner of any Affiliated Employer, treated separately, having Annual Compensation greater than $150,000.00. For this purpose no more than fifty (50) employees or, if lesser, the greater of three (3) employees or ten percent (10%) of the employees shall be treated as officers.

For purposes of determining the number of officers taken into account, the following employees shall be excluded: (1) employees who have not completed six (6) months of Vesting Service, (2) employees who normally work less than seventeen and one-half (17-1/2) hours per week, (3) employees who normally work not more than six (6) months during any year, (4) employees who have not attained the age of twenty-one (21), and (5) except to the extent provided in Regulations, employees who are included in a unit of employees covered by an agreement which the Secretary of Labor finds to be a collective bargaining agreement between employee representatives and an Affiliated Employer. Section 416(i) of the Code shall be used to determine percentage of ownership.

The determination of who is a Key Employee will be made in accordance with section 416(i) of the Code and applicable Regulations.

B-1

B.1.5 “Non-Key Employee” means any Employee who is not a Key Employee.

B.1.6 “Top-Heavy Plan” means any plan which has been determined to be top-heavy under the test described in Appendix B of the Plan.

PART B.2 Application

B.2.1 Application. The requirements described in this Appendix B shall apply to each Plan Year that the Plan is determined to be a Top-Heavy Plan.

B.2.2 Top-Heavy Test. If on the Determination Date the Aggregate Accounts of Key Employees in the Plan exceed 60 percent of the Aggregate Accounts of all Employees in the Plan, the Plan shall be a Top-Heavy Plan for that Plan Year. In addition, if the Plan is required to be included in an Aggregation Group and that group is a top-heavy group, the Plan shall be treated as a Top-Heavy Plan. An Aggregation Group is a top-heavy group if on the Determination Date the sum of (a) the present value of the cumulative accrued benefits for Key Employees under all defined benefit plans in the Aggregation Group which contains the Plan, plus (b) the total of all of the accounts of Key Employees under all defined contribution plans included in the Aggregation Group (which contains the Plan) is more than 60 percent of a similar sum determined for all employees covered in the Aggregation Group which contains the Plan.

In applying the above tests, the following rules shall apply:

(a) effective for Plan Years that begin on or after January 1, 2002, in determining the present value of the accumulated accrued benefits for any Employee or the amount in the account of any Employee, the value or amount shall be increased by all distributions made to or for the benefit of the Employee under the Plan after his Separation From Service and during the one-year period ending on the Determination Date;

(b) effective for Plan Years that begin on or after January 1, 2002, in determining the present value of the accumulated accrued benefits for any Employee or the amount in the account of any Employee, the value or amount shall be increased by all distributions made to or for the benefit of the Employee under the Plan prior to his Separation From Service and during the five-year period ending on the Determination Date;

(c) effective for Plan Years that begin prior to January 1, 2002, in determining the present value of the accumulated accrued benefits for any Employee or the amount in the account of any Employee, the value or amount shall be increased by all distributions made to or for the benefit of the Employee under the Plan during the five-year period ending on the Determination Date;

(d) all rollover contributions made by the Employee to the Plan shall not be considered by the Plan for either test;

(e) if an Employee is a Non-Key Employee under the Plan for the Plan Year but was a Key Employee under the Plan for a prior Plan Year, his Account shall not be considered;

(f) effective for Plan Years that begin on or after January 1, 2002, notwithstanding any other provision of the Plan, benefits shall not be taken into account in determining the top-heavy ratio for any Employee who has not performed services for the Employer during the last one-year period ending upon the Determination Date; and

(g) effective for Plan Years that begin prior to January 1, 2002, notwithstanding any other provision of the Plan, benefits shall not be taken into account in determining the top-heavy ratio for any

B-2

Employee who has not performed services for the Employer during the last five-year period ending upon the Determination Date.

B.2.3 Vesting Restrictions if Plan Becomes Top-Heavy. If a Participant has at least one Hour of Service during a Plan Year when the Plan is a Top-Heavy Plan, he shall either vest under each of the normal vesting provisions of the Plan or under the following vesting schedule, whichever is more favorable:

Completed Years of Active Service		Percentage of Amount Invested In Accounts Containing Employer Contributions

Less than two years		0
Two years but less than three years		20
Three years but less than four years		40
Four years but less than five years		60
Five years but less than six years		80
Six years or more		100

If the Plan ceases to be a Top-Heavy Plan, this requirement shall no longer apply. After that date, the normal vesting provisions of the Plan shall be applicable to all subsequent Contributions by the Employer. For purposes of this Section B.2.3 Years of Active Service shall be determined under the rules of section 411(a)(4), (5) and (6) of the Code except that Years of Active Service beginning prior to January 1, 1984 and Years of Active Service for any Plan Year for which the Plan was not top-heavy shall be disregarded. Also, any Year of Active Service shall be disregarded to the extent that such Year of Active Service occurs during a Plan Year when the Plan benefits (within the meaning of section 410(b) of the Code) no Key Employee or former Key Employee.

B.2.4 Minimum Contributions if Plan Becomes Top-Heavy. If the Plan is a Top-Heavy Plan and the normal allocation of the Employer Contribution and forfeitures is less than five percent of any Non-Key Employee Participant’s Annual Compensation, the Committee, without regard to the normal allocation procedures, shall allocate the Employer Contribution and the forfeitures among the Participants who are Non-Key Employees and who are in the employ of the Employer at the end of the Plan Year in proportion to each such Participant’s Annual Compensation until each Non-Key Employee Participant has had an amount equal to five percent of his Annual Compensation allocated to his Account. At that time, any more Employer Contributions or forfeitures shall be allocated under the normal allocation procedures described earlier in the Plan. Amounts that may be treated as Section 401(k) Contributions made on behalf of Non-Key Employees may not be included in determining the minimum contribution required under this Section to the extent that they are treated as Section 401(k) Contributions for purposes of the Actual Deferral Percentage test.

In applying this restriction, the following rules shall apply:

(a) Each Employee who is eligible for participation (without regard to whether he has made mandatory contributions, if any are required, or whether his compensation is less than a stated amount) shall be entitled to receive an allocation under this Section; and

(b) All defined contribution plans required to be included in the Aggregation Group shall be treated as one plan for purposes of meeting the three percent maximum; this required aggregation shall not apply if the Plan is also required to be included in an Aggregation Group which includes a defined benefit plan and the Plan enables that defined benefit plan to meet the requirements of sections 401(a)(4) or 410 of the Code.

B.2.5 Disregard of Government Programs. If the Plan is a Top-Heavy Plan, it must meet the vesting and benefit requirements described in this Article without taking into account contributions or benefits under

B-3

(g) to direct and instruct or to appoint an investment manager or managers which would have the power to direct and instruct the Trustee in all matters relating to the preservation, investment, reinvestment, management, and disposition of the Trust assets; provided, however, that the Committee shall have no authority that would prevent the Trustee from being an “agent independent of the issuer,” as that term is defined in Rule 10b-18 promulgated under the Securities Exchange Act of 1934, at any time that the Trustee’s failure to maintain such status would result in the Sponsor or any other person engaging in a “manipulative or deceptive device or contrivance” under the provisions of Rule 10b-6 of such Act;

(h) to direct and instruct the Trustee in all matters relating to the payment of Plan benefits and to determine a Participant’s or former Participant’s entitlement to a benefit should he appeal a denial of his claim for a benefit or any portion thereof; and

The Trustee, after being notified of any such delegation of power in writing, shall thereafter accept and may rely upon any document executed by such member or members as representing the action of the Committee until the Committee files with the Trustee a written revocation of that delegation of power.

C.6 Disqualification of Committee Members. A member of the Committee who is also a Participant of the Plan shall not vote or act upon any matter relating solely to himself.

C.7 Disclosure to Participants. The Committee shall make available to each Participant, former Participant, and Beneficiary for his examination such records, documents, and other data as are required under ERISA, but only at reasonable times during business hours. No Participant, former Participant, or Beneficiary shall have the right to examine any data or records reflecting the compensation paid to any other Participant, former Participant, or Beneficiary, and the Committee shall not be required to make any data or records available other than those required by ERISA.

C.8 Standard of Performance. The Committee and each of its members shall use the care, skill, prudence, and diligence under the circumstances then prevailing that a prudent man acting in a like capacity and familiar with such matters would use in conducting his business as the administrator of the Plan; shall, when exercising its power to direct investments, diversify the investments of the Plan so as to minimize the risk of large losses, unless under the circumstances it is clearly prudent not to do so; and shall otherwise act in accordance with the provisions of the Plan and ERISA.

C.9 Liability of Administrative Committee and Liability Insurance. No member of the Committee shall be liable for any act or omission of any other member of the Committee, the Trustee, any investment manager, or any Participant or former Participant who directs the investment of his Account or other agent appointed by the Committee except to the extent required by the terms of ERISA, and any other applicable state or federal law, which liability cannot be waived. No Participant of the Committee shall be liable for any act or omission on his own part except to the extent required by the terms of ERISA, and any other applicable state or federal law, which liability cannot be waived. In this connection, each provision hereof is severable and if any provision is found to be void as against public policy, it shall not affect the validity of any other provision hereof.

Further, it is specifically provided that the Trustee may, at the direction of the Committee, purchase out of the Trust assets insurance for the members of the Committee and any other fiduciaries appointed by the Committee, and for the Trust itself to cover liability or losses occurring by reason of the act or omission of any one or more of the members of the Committee or any other fiduciary appointed by them under the Plan, provided such insurance permits recourse by the insurer against the members of the Committee or the other fiduciaries concerned in the case of a breach of a fiduciary obligation by one or more members of the Committee or other fiduciary covered thereby.

C.15 Standard of Judicial Review of Committee Actions. The Committee has full and absolute discretion in the exercise of each and every aspect of its authority under the Plan, including without limitation, the authority to determine any person’s right to benefits under the Plan, the correct amount and form of any such benefits; the authority to decide any appeal; the authority to review and correct the actions of any prior administrative committee; and all of the rights, powers, and authorities specified in this Appendix and elsewhere in the Plan. Notwithstanding any provision of law or any explicit or implicit provision of this document, any action taken, or ruling or decision made, by the Committee in the exercise of any of its powers and authorities under the Plan will be final and conclusive as to all parties other than the Sponsor or Trustee, including without limitation all Participants, former Participants and Beneficiaries, regardless of whether the Committee or one or more members thereof may have an actual or potential conflict of interest with respect to the subject matter of such action, ruling, or decision. No such final action, ruling, or decision of the Committee will be subject to de novo review in any judicial proceeding; and no such final action, ruling, or decision of the Committee may be set aside unless it is held to have been arbitrary and capricious by a final judgment of a court having jurisdiction with respect to the issue.

APPENDIX D

FUNDING

D.1 Benefits Provided Solely by Trust. All benefits payable under the Plan shall be paid or provided for solely from the Trust, and the Employer assumes no liability or responsibility therefor.

D.2 Funding of Plan. The Plan shall be funded by one or more separate Trusts. If more than one Trust is used, each Trust shall be designated by the name of the Plan followed by a number assigned by the Committee at the time the Trust is established.

D.3 Incorporation of Trust. Each Trust is a part of the Plan. All rights or benefits which accrue to a person under the Plan shall be subject also to the terms of the agreements creating the Trust or Trusts and any amendments to them which are not in direct conflict with the Plan.

D.4 Authority of Trustee. Each Trustee shall have full title and legal ownership of the assets in the separate Trust which, from time to time, are in his separate possession. No other Trustee shall have joint title to or joint legal ownership of any asset in one of the other Trusts held by another Trustee. Each Trustee shall be governed separately by the trust agreement entered into between the Employer and that Trustee and the terms of the Plan without regard to any other agreement entered into between any other Trustee and the Employer as a part of the Plan.

D.5 Allocation of Responsibility. To the fullest extent permitted under section 405 of ERISA, the agreements entered into between the Employer and each of the Trustees shall be interpreted to allocate to each Trustee its specific responsibilities, obligations and duties so as to relieve all other Trustees from liability either through the agreement, Plan or ERISA, for any act of any other Trustee which results in a loss to the Plan because of his act or failure to act.

D.6 Trustee’s Fees and Expenses. The Trustee shall receive for its services as Trustee hereunder the compensation which from time to time may be agreed upon by the Sponsor and the Trustee. All of such compensation, together with the expenses incurred by the Trustee in connection with the administration of this Trust, including fees for legal services rendered to the Trustee, all other charges and disbursements of the Trustee, and all other expenses of the Plan shall be charged to and deducted from the Trust Fund, unless the Sponsor elects in writing to have any part or all of such compensation, expenses, charges, and disbursements paid directly by the Sponsor. The Trustee shall deduct from and charge against the Trust assets any and all taxes paid by it which may be levied or assessed upon or in respect of the Trust hereunder or the income thereof, and shall equitably allocate the same among the several Participants and former Participants.

APPENDIX E

OPTIONAL FORMS OF DISTRIBUTION

Subject to Sections 5.04, 5.07 and 5.08 of the Plan, in addition to the forms of distribution available under Section 5.03 of the Plan, the optional forms of distributions set forth below shall be available on and after the date on which the Sponsor elects to treat the Plan and the Quanex Corporation Salaried Employees’ Pension Plan as one plan for purposes of section 410(b) of the Code:

1. Option A. A pension under which the Participant or former Participant shall receive equal monthly payments for his lifetime.

2. Option B. A last survivor pension under which the Participant or former Participant shall receive 85 percent of the monthly pension benefit otherwise payable under Option A, and upon the death of the Participant or former Participant, the Beneficiary shall receive ½ of the monthly pension benefit paid to the Participant or former Participant prior to this death, provided however, that if the Beneficiary is younger than the Participant or former Participant, the 85 percent factor shall be reduced by one percent for each full year’s difference in the age of the Participant or former Participant and the Beneficiary, and if the Beneficiary is older than the Participant or former Participant, the 85 percent factor shall be increased by one percent for each full years difference in the age of the Participant or former Participant and the Beneficiary (up to a maximum of 100 percent).

3. Option C. A last survivor pension under which the Participant or former Participant shall receive 70 percent of the monthly pension benefit otherwise payable under Option A, and upon the death of the Participant or former Participant, the Beneficiary shall receive a monthly pension benefit equal to that paid to the Participant or former Participant.

4. Option D. A reduced monthly pension payable to the Participant or former Participant during his lifetime, provided that, if the Participant or former Participant dies prior to his receipt of an amount equal to 120 monthly payments, the then-present value of the remainder of such 120 monthly payments shall be payable to his Beneficiary in a lump sum. If the former Participant dies prior to his receipt of all of such 120 payments without having designated a Beneficiary, of if the Beneficiary predeceases the former Participant, the then-present value of any remaining payments shall be paid in a lump sum to the former Participant’s estate. If the designated Beneficiary dies after the former Participant and before all of such 120 monthly payments have been made, the then-present value of the unpaid balance of such payments shall be paid in a lump sum to the Beneficiary’s estate.

5. Limitations on Options B, C and D.

(a) Options A, B and C will not be available to any Participant if the reduced pension is less than $10 per month.

(b) Except as otherwise provided elsewhere in the Plan, any election shall be automatically revoked if either the Participant or former Participant or Beneficiary dies before the Participant’s or former Participant’s Annuity Starting Date.

(c) Where the Beneficiary is a person other than the Participant’s or former Participant’s Spouse, the Beneficiary under either Option B or Option C must be of such age and sex that the amount payable to the Participant or former Participant will exceed 50 percent of the amount that would otherwise be payable if the Participant or former Participant had elected a life annuity for his life.
