A.M. CASTLE & CO.
401(k) SAVINGS AND RETIREMENT PLAN

(As amended through April 27, 2009)

SECTION 1

General

1.1. History and Effective Date. Effective January 1, 1957, A. M. Castle & Co., an Illinois corporation, established the A. M. CASTLE & CO. SALARIED EMPLOYEES PROFIT SHARING PLAN (the “Plan”) for the benefit of its eligible employees. Effective as of April 26, 1967, ▇. ▇. ▇▇▇▇▇▇ & Co., a Delaware corporation (the “Company”), was substituted as the “Company” under the terms of the Plan. Effective as of January 1, 1978, the name of the Plan was changed to A. M. CASTLE & CO. EMPLOYEES PROFIT SHARING PLAN. Effective January 1, 1992, the Plan was amended and restated to incorporate a cash-or-deferred arrangement under Section 401(k) of the Internal Revenue Code of 1986, as amended (the “Code”). Effective August 1, 1994, the Plan was amended to extend eligibility on a restricted basis to members of certain collective bargaining groups. Effective January 1, 1996, the Plan was amended to provide for discretionary employer contributions payable quarterly in cash or in common stock of the Company. The Plan was again amended and restated, effective as of January 1, 1997. The Plan was most recently amended and restated effective January 1, 2003, and has been amended from time to time thereafter. The following provisions constitute a further amendment, restatement, and continuation of the Plan, which has been renamed the A. M. CASTLE & CO. 401(k) SAVINGS AND RETIREMENT PLAN, as in effect immediately prior to July 1, 2008, the “Effective Date” of the Plan as set forth herein; provided, however, that if any provision of the Plan specifically provides for an earlier or later effective date, such provision shall be deemed an amendment of the Plan as in effect on such earlier or later date. Except as may be expressly provided herein, the entitlement to any benefit under the Plan of any individual whose employment with the Employers and Related Companies (as defined in subsection 1.2) terminated prior to the Effective Date shall be determined under the terms of the Plan as in effect on the date of such termination of employment. The Plan is intended to qualify as a profit-sharing plan under Section 401 (a) of the Code.

1.2. Related Companies and Employers. The term “Related Company” means any corporation or trade or business during any period during which it is, along with the Company, a member of a controlled group of corporations or a controlled group of trades or businesses, as described in Sections 414(b) and 414(c), respectively, of the Code. The Company and each Related Company, which, with the Company’s consent, adopts the Plan are referred to below collectively as the “Employers” and individually as an “Employer.”

1.3. Trust Agreement, Plan Administration. All contributions made under the Plan will continue to be held, managed and controlled by one or more trustees (the “Trustee”) acting under one or more trusts which form a part of the Plan. The terms of the trusts as in effect on the Effective Date are set forth in two trust agreements known as A. M. CASTLE & CO. EMPLOYEES PROFIT SHARING TRUST and ▇. ▇. ▇▇▇▇▇▇ & CO. EMPLOYEES TRUST, to which the provisions of and benefits under the Plan are subject. These trusts, together with any other trusts maintained under the Plan, are referred to herein as the “Trust.” The authority to control and manage the operation and administration of the Plan is vested in an Administration Committee as described in subsection 12.1. The members of the Administration Committee shall be “named fiduciaries,” as described in Section 402 of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), with respect to their authority under the Plan. The Chairman of the Administration Committee shall be the Administrator of the Plan and shall have the rights, duties and obligations of an “administrator” as that term is defined in Section 3(16)(A) of ERISA and of a “plan administrator” as that term is defined in Section 414(g) of the Code.

1.4. Plan Year. The term “Plan Year” means the twelve-consecutive-month period beginning on each January 1.

1.5. Accounting Dates. Except as otherwise provided by the Administration Committee, the term “Accounting Date” means each business day.

1.6. Applicable Laws. The Plan shall be construed and administered in accordance with the internal laws of the State of Illinois to the extent that such laws are not preempted by the laws of the United States of America.

1.7. Gender and Number. Where the context admits, words in any gender shall include any other gender, words in the singular shall include the plural and the plural shall include the singular.

1.8. Notices. Any notice or document required to be filed with the Administration Committee under the Plan will be properly filed if delivered or mailed by registered mail, postage prepaid, to the Administration Committee, in care of the Company, at its principal executive offices. Any notice required under the Plan may be waived by the person entitled to notice.

1.9. Form and Time of Elections. Except as otherwise provided by the Administration Committee, any election or consent permitted or required to be made under the Plan, and any permitted modification or revocation thereof, shall be made in writing or other manner permitted by the Administration Committee and at such time as the Administration Committee may require. The Administration Committee may permit or require that some or all transactions be effected through a telephone, internet or other electronic system utilizing a personal identification number (“PIN”) or password, the use of which shall constitute a valid signature for purposes of any transaction for which use of such system is authorized or required by the Administration Committee.

1.10. Evidence. Evidence required of anyone under the Plan may be by certificate, affidavit, document or other information which the person acting on it considers pertinent and reliable, and signed, made or presented by the proper party or parties.

1.11. Action By Employers. Any action required or permitted to be taken by an Employer under the Plan shall be by resolution of its Board of Directors or by a person or persons authorized by resolution of its Board of Directors.

1.12. No Reversion to Employers. No part of the corpus or income of the Trust shall revert to any Employer or be used for, or diverted to, purposes other than for the exclusive benefit of Participants and other persons entitled to benefits under the Plan, except as specifically provided in the Trust Agreement.

1.13. Plan Supplements. The provisions of the Plan as applied to any Employer or any group of employees of any Employer may, with the consent of the Company, be modified or supplemented from time to time by the adoption of one or more Supplements. Each Supplement shall form a part of the Plan as of the Supplement’s effective date. In the event of any inconsistency between a Supplement and the Plan document, the terms of the Supplement shall govern.

1.14. Defined Terms. Terms used frequently with the same meaning are indicated by initial capital letters, and are defined throughout the Plan. Appendix A contains an alphabetical listing of all such terms and the subsections in which they are defined.

SECTION 2

Participation in Plan

2.1. Eligibility For Participation. Subject to the terms and conditions of the Plan, each employee of an Employer who was a Participant in the Plan immediately prior to the Effective Date shall continue as such on and after that date. Subject to the terms and conditions of the Plan, each other employee of an Employer will become a Participant on the first January 1, April 1, July 1 or October 1 thereafter on which he meets all of the following requirements:

	(a)		he has completed at least one Year of Service (as defined in subsection 3.1);

	(b)		he is a member of a group to whom the Plan has been and continues to be extended, either by the unilateral action of his Employer in the case of an employee who is not covered by a collective bargaining agreement, or through a currently effective collective bargaining agreement between his Employer and the collective bargaining representative of the group of employees of which he is a member; and

	(c)		he is not then laid off from the Employers.

Effective as of the Effective Date, the Plan is extended to each employee of an Employer whose wages and benefits from that Employer are not the subject of a collective bargaining agreement, except that the Plan

is not extended to persons who are employed solely in any division of any Employer established or acquired by the Employer after December 31, 1983 or, if later, the date the Employer adopts the Plan. Notwithstanding the foregoing provisions of this subsection 2.1: (i) if an individual is employed or reemployed by an Employer on or after the first January 1, April 1, July 1 or October 1 coincident with or next following the date on which he satisfies the requirements of paragraph (a) next above, he shall become a Participant in the Plan immediately upon meeting the requirements of paragraphs (b) and (c) next above; and (ii) no individual is eligible to participate in the Plan who provides services to an Employer under a contract, arrangement or understanding with such individual or with an agency or leasing organization that treats the individual as either an independent contractor or an employee of such agency or leasing organization, even if such individual is later determined (by judicial action or otherwise) to have been a common law employee of an Employer rather than an independent contractor or an employee of such agency or leasing organization.

2.2. Limited Participation after Loss of Eligible Status. Once an employee becomes a Participant in the Plan, he will remain a Participant for all purposes under the Plan as long as he continues to have an Account balance under the Plan, except that if an employee of an Employer or Related Company ceases to meet the eligibility requirements of paragraph 2.1(b) or 2.1(c) he will no longer be eligible to make After-Tax Contributions or to have Before-Tax Contributions made for him pursuant to Section 4 or to receive Matching Contributions or Employer Contributions pursuant to Section 5 and subsection 7.3, and if a Participant also ceases to be an employee of an Employer or Related Company, in addition to the foregoing restrictions, he will no longer be eligible to borrow in accordance with subsection 10.1 or withdraw from his Account pursuant to subsection 10.2.

2.3. Limited Participation By Members of Collective Bargaining Units. If an employee of an Employer becomes a Participant in the Plan by reason of the terms of a currently effective collective bargaining agreement, he shall participate in the Plan for all purposes except that no such union member shall receive Employer Contributions pursuant to subsection 5.1 and 7.3 or Matching Contributions under subsection 5.2, except to the extent otherwise specifically provided by the terms of a currently effective collective bargaining agreement.

2.4. Limited Participation for Purposes of Before-Tax Contributions and After-Tax Contributions. An employee of an Employer who meets the requirements of subsection 2.1 (other than paragraph 2.1 (a) thereof) shall be eligible to make After-Tax Contributions (as described in subsection 4.2) to the Plan and to have Before-Tax Contributions (as described in subsection 4.1) made to the Plan on his behalf effective as of the first day of the calendar month that is at least 30 days after the first date on which he is paid or entitled to payment for the performance of services for an Employer; provided, however, that an employee who is classified on an Employer’s payroll records as a temporary employee shall not be eligible to make After-Tax Contributions or to have Before-Tax Contributions made on his behalf to the Plan until such time as he completes one Year of Service. An employee who makes such contributions prior to the date on which he first becomes a Participant in accordance with subsection 2.1 shall be treated as a Participant for all purposes of the Plan except that he shall not be eligible to receive an Employer Contribution pursuant to subsections 5.1 and 7.3 and, if he is union member, he shall not be eligible for Matching Contributions under subsection 5.2 (except to the extent otherwise specifically provided by the terms of a currently effective collective bargaining agreement).

2.5. Plan Not Contract of Employment. The Plan does not constitute a contract of employment, and participation in the Plan will not give any employee or Participant the right to be retained in the employ of any Employer nor any right or claim to any benefit under the Plan, unless such right or claim has specifically accrued under the terms of the Plan.

2.6. Leased Employees. If a person satisfies the requirements of Section 414(n) of the Code and applicable regulations for treatment as a Leased Employee with respect to an Employer, a Related Company or any other entity required to be aggregated with an Employer pursuant to Section 414(m) of the Code, such Leased Employee shall not be eligible to participate in this Plan or in any other plan maintained by an Employer or a Related Company which is qualified under Section 401(a) of the Code, but, to the extent required by Section 414(n) of the Code and applicable Treasury regulations, such person shall be treated as if the services performed by him in such capacity were performed by him as an employee of a Related Company which has not adopted the Plan; provided, however, that no such service shall be credited:

(a)

for any period during which not more than 20% of the non-highly Compensated workforce of the Employers and the Related Companies consists of Leased Employees and the Leased Employee is a participant in a money purchase pension plan maintained by the leasing organization which (i)

			provides for a nonintegrated employer contribution of at least 10 percent of compensation, (ii) provides for full and immediate vesting, and (iii) covers all employees of the leasing organization (beginning with the date they become employees), other than those employees excluded under Section 414(n)(5) of the Code; or

	(b)		for any other period unless the Leased Employee provides satisfactory evidence to the Employer or Related Company that he meets all of the conditions of this subsection 2.6 and applicable law required for treatment as a Leased Employee.

			For purposes of paragraph (a) above, “Highly Compensated” shall have the meaning set forth in subsection 8.12.

SECTION 3

Service

3.1. Years of Service. Subject to the provisions of subsection 3.4, an employee’s or Participant’s “Years of Service” as at any date equals the year or years and any portion thereof elapsed since the first date for which he was paid or entitled to payment for the performance of duties for an Employer or Related Company, subject to the following:

	(a)		For all purposes of the Plan, if an employee’s or Participant’s employment with the Employers and the Related Companies is terminated on a Termination Date or, if he is laid off from an Employer or Related Company, and he is not paid or entitled to payment for the performance of duties for an Employer or Related Company for the 12-consecutive-month period commencing on such Termination Date or, if earlier, the date he is laid off, he shall not be credited with service for the period between the date of his termination of employment or, if earlier, the first anniversary of the date he is laid off from an Employer or Related Company without recall, and the first date thereafter for which he is paid or entitled to payment for the performance of duties for an Employer or Related Company.

	(b)		For all purposes of the Plan other than subsection 2.1, a Participant’s Years of Service for the period elapsed between his initial date of hire and January 1, 1976, shall be equal to his “years of service” as an “Employee,” both as defined and determined under the terms of the Plan as in effect on December 31, 1975, excluding, however, years of service completed prior to a break in participation if such service would be disregarded under the terms of the Plan as in effect on December 31, 1975, for purposes of determining the Participant’s vested interest under the Plan.

	(c)		For purposes of determining whether a Participant has a nonforfeitable interest in his Employer Account accrued prior to the date he incurs five consecutive One Year Breaks in Service (or prior to the date he incurs a One Year Break in Service, if it is incurred before January 1, 1985), a Participant’s number of Years of Service accrued after such five consecutive One Year Breaks in Service (or, if the break in service was incurred before January 1, 1985, such One Year Break in Service) shall be disregarded.

3.2. One Year Break in Service. The term “One Year Break in Service” means, with respect to any employee or Participant, the 12-consecutive-month period commencing on the date of his termination of employment with the Employers and Related Companies or, if earlier, the first anniversary of a layoff by the Employers and Related Companies without recall, if he is not paid or entitled to payment for the performance of duties for an Employer or Related Company during that period. Notwithstanding the foregoing, solely for purposes of determining whether a One Year Break in Service has occurred, if an employee is absent from service on account of a Maternity or Paternity Absence (as defined below) beyond the first anniversary of the date on which such absence began, a One Year Break in Service shall not occur until the third anniversary of the first day of such absence. For all other purposes hereunder, however, no portion of such Maternity or Paternity absence occurring after the first anniversary of the first day thereof shall be credited as part of a Year of Service. The term “Maternity or Paternity Absence” means an employee’s absence from work which commences on or after January 1, 1985

because of the pregnancy of such individual, the birth of a child of such individual, the placement of a child with such individual in connection with the adoption of a child by such individual, or for purposes of caring for the child by such individual immediately following such birth or placement. The Administration Committee may require the employee to furnish such information as it considers necessary to establish that such individual’s absence was a Maternity or Paternity Absence. An absence on account of a period of leave required by the Family Medical Leave Act of 1993 shall not be counted towards a One Year Break in Service.

3.3. Veterans’ Rights. Notwithstanding any other provision of the Plan to the contrary, contributions, benefits and service with respect to qualified military service will be provided in accordance with Section 414(u) of the Code. The provisions of this subsection 3.3 shall be effective as of December 12, 1994 with respect to Participants employed on or after that date.

3.4. Year of Service for Temporary Employees. Solely for purposes of subsections 2.1 and 2.4, with respect to an employee who is classified on the Employer’s payroll records as a temporary employee, the term one “Year of Service” means a 12-consecutive month period of employment with the Employer or any Related Company beginning on the date on which such employee first completes an Hour of Service upon hire or rehire, or on any anniversary thereof, in which he first completes at least 1,000 Hours of Service. For purposes of computing Hours of Service under this subsection 3.4, a temporary employee shall be credited with 45 Hours of Service for each week, if any, during which such employee is required to be credited with at least one Hour of Service.

3.5. Hours of Service. The term “Hours of Service” means, with respect to any computation period:

	(a)		each hour for which the employee is paid or entitled to payment for the performance of duties for the Employer or a Related Company;

	(b)		each hour for which the employee is paid or entitled to payment by the Employer or a Related Company on account of a period during which no duties are performed (whether or not the employment relationship has terminated) due to vacation, holiday, illness, incapacity (including disability), layoff, jury duty, military duty or leave of absence, but not more than 501 hours for any single continuous period; and

	(c)		each hour for which back pay, irrespective of mitigation of damages, is either awarded or agreed to by the Employer or a Related Company, excluding any hour already credited under paragraph (a) or (b) next above, which shall be credited to the computation period or period to which the award, agreement or payment pertains rather than to the computation period in which the award, agreement or payment is made.

No hours shall be credited on account of any period during which the employee performs no duties and receives payment solely for the purpose of complying with unemployment compensation, workers’ compensation or disability insurance laws. Hour of Service required to be credited under this subsection 3.5 shall be determined in accordance with Title 29 of the Code of Federal Regulations, Section 2530.200b-2(b) and (c).

SECTION 4

Before-Tax Contributions and After-Tax Contributions

4.1. Before-Tax Contribution. Subject to the terms and conditions of the Plan, a Participant may elect as follows:

(a)

Subject to the limitations set forth in Section 4.7 and Section 8 of the Plan and such additional rules as the Administration Committee may establish on a uniform and nondiscriminatory basis, for any Plan Year, a Participant may elect to have his salary or wages reduced, and a corresponding amount contributed on his behalf to the Plan by his Employer as a “Before-Tax Contribution,” which amount shall not exceed one hundred percent (100%) of his Eligible Compensation (as defined in subsection 4.6) for that year, reduced by the amount determined by the Administration Committee to be necessary to satisfy any tax or other applicable withholding requirements, including any voluntary deductions elected by the Participant such as salary reductions pursuant to Section 125 or 132(f)(4) of the Code.

(b)

All Participants who are eligible to make Before-Tax Contributions under this Plan for any Plan Year pursuant to paragraph (a) next above and who have attained age 50 before the close of such Plan Year shall be eligible to make, in addition to the Before-Tax Contributions described in paragraph (a) next above, “catch-up” Before-Tax Contributions in accordance with, and subject to the limitations of, Section 414(v) of the Code and such additional rules as the Committee may establish on a uniform and nondiscriminatory basis. Such catch-up Before-Tax Contributions shall not be taken into account for purposes of the limitations on Before-Tax Contributions described in paragraph (a) next above, or for purposes of the provisions of the Plan implementing the required limitations of Code Sections 402(g) and 415. The Plan shall not be treated as failing to satisfy the provisions of the Plan implementing the requirements of Section 401(k)(3), 410(b) or 416 of the Code, as applicable, by reason of the making of such catch-up Before-Tax Contributions.

4.2. After-Tax Contributions. Subject to the limitations set forth in subsection 4.7 and Section 8 and such additional rules as the Administration Committee may establish on a uniform and nondiscriminatory basis, for any Plan Year, a Participant may elect to make “After-Tax Contributions” to the Plan through payroll deduction in an amount expressed in a whole percentage not greater than five percent of his Eligible Compensation for that year. Any election pursuant to this subsection 4.2 shall be made and given effect in accordance with such uniform rules and procedures as the Administration Committee may provide from time to time.

4.3. Payment of Before-Tax and After-Tax Contributions. Before-Tax Contributions and After-Tax Contributions shall be made each payroll period, and shall be paid to the Trustee by the Employer on the earliest date on which such contributions can reasonably be segregated from the Employer’s general assets, but in no event later than the 15^th business day of the month following the month in which such amounts would otherwise have been payable to the Participant.

4.4. Variation, Discontinuance and Resumption of Before-Tax or After-Tax Contributions. Subject to such rules and restrictions as the Administration Committee may establish on a uniform and nondiscriminatory basis, a Participant may elect to change his Before-Tax Contribution or After-Tax Contribution rate (or both) (but not retroactively) within the limits specified in subsections 4.1 and 4.2, and may elect to discontinue either or both such contributions or to have them resumed.

4.5. Rollover Contributions. A Participant or an employee who meets the requirements of subsection 2.1 other than paragraph (a) thereof may make, with the consent of the Administration Committee, a Rollover Contribution (as defined below) to the Plan. The term “Rollover Contribution” means a rollover contribution of all or part of a cash distribution from a qualified plan of another employer which, under applicable provisions of the Code, is permitted to be rolled over to an eligible retirement plan. Notwithstanding the foregoing, in no event shall a Participant be permitted to make a rollover contribution of (a) amounts previously contributed to another plan on an after-tax basis, or (b) amounts distributed from (i) a qualified plan described in Section 403(a) of the Code, (ii) an annuity contract described in Section 403(b) of the Code, (iii) an eligible plan described in Section 457(b) of the Code. If an employee who is not otherwise a Participant makes a Rollover Contribution to the Plan, he shall be treated as a Participant only with respect to his Rollover Contribution Account (defined in subsection 7.1) until he has met all of the requirements for Plan participation set forth in subsection 2.1.

4.6. Eligible Compensation. For purposes of this Section 4, Section 5, and Subsection 7.3, the term “Eligible Compensation” means for any Plan Year:

(a)

all compensation reported for purposes of Federal income tax withholding for such year on Form W-2 for services performed for an Employer paid prior to the Participant’s termination of employment, excluding the following items (even if includable in gross income): non-cash compensation, reimbursements and expense allowances, fringe benefits, severance pay and any compensation paid during any portion of the Plan Year during which an employee was not yet a Participant except that such pre-participation compensation shall not be excluded in determining a Participant’s Eligible Compensation for purposes of paragraph 7.3(c) and 11.7(b) (relating to Employer Contributions and forfeitures) for the Plan Year in which an employee first becomes a Participant in the Plan; plus

(b)

the amount of any Before-Tax Contributions and any other elective contributions made on his behalf for such Plan Year to a plan sponsored by an Employer that are not includable in the Participant’s gross income pursuant to Code Section 125, 402(e)(3) or 132(f)(4).

4.7. Limitation on the Amount of Compensation Taken Into Account For Any Plan Year. Notwithstanding any other provision of the Plan to the contrary, the amount of Eligible Compensation that may be taken into account under the Plan for any Plan Year for purposes of applying the annual percentage limitations of subsections 4.1, 4.2 and 5.2 or the allocation formula of paragraph 7.3(b) shall not exceed $200,000 or such other maximum amount as may be permitted for any Plan Year under Section 401(a)(17) of the Code, taking into account for purposes of such limitation any proration required where Eligible Compensation is computed with respect to a period less than a full year (other than on account of mid-year commencement or cessation of participation). The annual Eligible Compensation of each Participant taken into account in determining allocations under subsection 4.1, 4.2 and 5.2 or the allocation formula of paragraph 7.3(b) of the Plan for any Plan Year beginning after December 31, 2001 shall not exceed $200,000, as adjusted for cost-of-living increases in accordance with Section 401(a)(17) of the Code. Annual Eligible Compensation means Eligible Compensation during the Plan Year or such other consecutive 12-month period over which Eligible Compensation is otherwise determined under the Plan (the determination period). The cost-of-living adjustment in effect for a calendar year applies to annual Eligible Compensation for the determination period that begins with or within such calendar year.

SECTION 5

Employer Contributions

5.1. Employer Contributions. For each calendar quarter beginning before January 1, 2005, for each of the 2005, 2006 and 2007 Plan Years, and for the six month period of January 1, 2008 through June 30, 2008, each Employer shall make an ‘Employer Contribution’ to the Plan in such amounts (if any) as is determined by the Company in its sole discretion with respect to the eligible Participants of each strategic business unit of that Employer described in Appendix B of the Plan (a ‘Business Unit’). On and after June 30, 2008, the Employers shall no longer make any Employer Contribution determined in the discretion of the Company as applied to Business Units, but shall instead make as of each payroll period a uniform Employer Contribution equal to 4 percent of each Participant’s Eligible Compensation for that payroll period; provided that, except in the case of any hourly warehouse employee employed at the Hammond, Indiana location who is represented by the United Steelworkers of America, but in such case subject to subsection 2.3, the Employers shall not make any Employer Contribution for the 2009 Plan Year effective for payroll periods beginning on or after April 27, 2009 (or for any such Plan Year or Plan Years beginning on or after January 1, 2010, or any portions thereof, as is determined by the Company in its sole discretion). To clarify how the Employer Contribution will be calculated for the 2008 Plan Year, the Employer Contribution shall equal the sum of the discretionary Employer Contribution determined for each Business Unit which shall be determined based on the financial performance of each Business Unit through June 30, 2008 plus a non-discretionary Employer Contribution equal to 4 percent of each Participant’s Eligible Compensation earned on and after July 1, 2008 and before January 1, 2009.

5.2. Matching Contributions. Subject to the conditions and limitations of subsections 2.3 and 4.7 and Section 8, for each Plan Year, each Employer shall make a ‘Matching Contribution’ to the Plan on behalf of each Participant employed by such Employer in an amount equal to 50 percent (or such larger percentage as the Company may determine with respect to any Plan Year) of the Before-Tax Contributions (excluding catch-up Before-Tax Contributions) made on behalf of the Participant that do not exceed 6 percent of such Participant’s Eligible Compensation for each payroll period; provided that, except in the case of any hourly warehouse employee employed at the Hammond, Indiana location who is represented by the United Steelworkers of America, but in such case subject to subsection 2.3, the Employers shall not make any Matching Contribution for the 2009 Plan Year effective for Before-Tax Contributions attributable to payroll periods beginning on or after April 27, 2009 (or for any such Plan Year or Plan Years beginning on or after January 1, 2010, or any portions thereof, as is determined by the Company in its sole discretion). For Before-Tax Contributions made on behalf of the Participant prior to July 1, 2008, the reference in the preceding sentence to ‘50 percent’ was ‘25 percent,’ and the Employer had the ability to designate different Matching Contribution percentages for different Business Units.

5.3. Qualified Matching and Qualified Nonelective Contributions. For any Plan Year, each Employer shall make a “Qualified Matching Contribution” and/or a “Qualified Nonelective Contribution” on behalf of some or

all of the Participants employed by that Employer who are not Highly Compensated (as defined in subsection 8.12) in an amount equal to such percentage, if any, of their Before-Tax Contributions (excluding catch-up Before-Tax Contributions) or Eligible Compensation as the Company, in its sole discretion, may determine with respect to that Employer. Any such qualified Matching Contributions or Qualified Nonelective Contributions (and any earnings thereon) shall be nonforfeitable at all times and shall be distributable only in the event of:

	(a)		the Participant’s attainment of age 59¹/2;

	(b)		for Plan Years beginning before January 1, 2002, the Participant’s separation from service or a qualifying sale of a subsidiary or business of the Employer (within the meaning of Section 401(k)(2)(B) of the Code as then in effect); or

	(c)		for Plan Years beginning after December 31, 2001, the Participant’s separation from employment (within the meaning of Section 401(k)(2)(B) of the Code as amended by the Economic Growth and Tax Relief Reconciliation Act of 2001).

5.4. Limitations on Amount of Employer Contributions. In no event shall the sum of any Before-Tax, Employer, Matching, Qualified Matching and Qualified Nonelective Contributions made by an Employer for any Plan Year exceed the limitations imposed by Section 404 of the Code on the maximum amount deductible on account thereof by the Employer for that year.

5.5. Payment of Employer, Matching and Qualified Matching and Qualified Nonelective Contributions. Each Employer’s contributions under the Plan (other than Before-Tax Contributions) for a Plan Year shall be paid to the Trustee, without interest, no later than the time prescribed by law for filing the Employer’s federal income tax return, including any extensions thereof.

5.6. Forfeiture of Matching Contributions. Notwithstanding any other provision of the Plan, any portion of a Matching Contribution attributable to Before-Tax Contributions that are distributed as excess deferrals or excess contributions in accordance with subsections 8.6 or 8.8 shall be forfeited and applied in accordance with subsection 11.6.

5.7. Special Employer Contribution. In addition to any contribution provided under subsection 5.1, effective on and after July 1, 2008 the Employers shall make an additional Employer Contribution equal to: (a) 3 percent of each Transition A Participant’s Eligible Compensation earned on and after July 1, 2008; and (b) 6 percent of each Transition B Participant’s Eligible Compensation earned on and after July 1, 2008; provided that, except in the case of any hourly warehouse employee employed at the Hammond, Indiana location who is represented by the United Steelworkers of America, but in such case subject to subsection 2.3, the Employers shall not make any such additional Employer Contribution on behalf of a Transition A Participant or a Transition B Participant for the 2009 Plan Year effective for payroll periods beginning on or after April 27, 2009 (or for any such Plan Year or Plan Years beginning on or after January 1, 2010, or any portions thereof, as is determined by the Company in its sole discretion). A ‘Transition A Participant’ means any Participant who, as of June 30, 2008, participated in the A.M. Castle & Co. Hourly Employees Retirement Plan or the A.M. Castle & Co. Salaried Employees Retirement Plan, is actively employed by an Employer, is at least age 40, has at least 5 Years of Service and is not a Transition B Participant. A ‘Transition B Participant’ means any Participant who, as of June 30, 2008, participated in the A.M. Castle & Co. Hourly Employees Retirement Plan or the A.M. Castle & Co. Salaried Employees Retirement Plan, is actively employed by an Employer, is at least age 50 and has at least 5 Years of Service. A Transition A Participant or Transition B Participant shall remain eligible for the special Employer Contribution provided by this Section 5.7, if any, only for so long as he remains continuously employed by an Employer.

SECTION 6

Investment of the Trust Fund

6.1. The Trust Fund and Investment Funds. The Trust Fund as at any date consists of all property of every kind then held by the Trustee. The Administration Committee shall maintain such Investment Funds from time to time as it deems appropriate, in its discretion, for the investment of Participants’ Accounts, which funds shall include a “Loan Fund” which shall consist of promissory notes evidencing loans made to Participants in accordance with subsection 10.1 and a “Company Stock Fund” which shall be invested in Common Stock of the Company and

short term investments as necessary for liquidity. The Administration Committee, in its discretion, may discontinue (or direct the discontinuance of) any Investment Fund or Investment Funds as it shall from time to time consider appropriate and in the best interest of Participants, and may establish such rules and procedures for the orderly transfer and investment of funds held under a discontinued Investment Fund to one or more other Investment Funds then maintained under the Plan. A separate “Fund Account” shall be established by the Administration Committee to reflect the portion, if any, of each of a Participant’s Accounts that is invested in each of the Investment Funds.

Effective January 1, 2007, each Participant who has at least three Years of Service, any alternate payee who has an Account under the Plan with respect to a Participant who has at least three Years of Service, or the beneficiary of a deceased Participant shall be permitted to elect to transfer as of any valuation date all or any portion of his Account invested in the Company Stock Fund to any of the other funds maintained by the Trustee. The Administration Committee may adopt such additional policies and procedures as it determines, in its sole discretion, are necessary or appropriate to facilitate the preceding sentence as long as such additional policies and procedures do not impose restrictions or conditions with respect to the transfer of investments from the Company Stock Fund to any other investment fund available under the Plan that are not imposed on the investment of other assets of the Plan and as long as such additional policies and procedures are consistent with the requirements of Section 401(a)(35) of the Code.

6.2. Investment Fund Elections. Subject to the provisions of this subsection 6.2 and such uniform rules and procedures as may be established by the Administration Committee, an eligible Participant may elect:

	(a)		to have the contributions to his Account (other than Employer Contributions described in subsection 5.1) invested in any one or more of the Investment Funds (other than the Loan Fund) then maintained in accordance with subsection 6.1, and may change or revoke any such election; and

	(b)		to change the allocation of his existing account balances (excluding, for periods prior to January 1, 2004, amounts attributable to Employer Contributions made after January 1, 1996) among the Investment Funds (other than the Loan Fund) then maintained in accordance with subsection 6.1.

Employer Contributions made after January 1, 1996 (and the earnings thereon) shall be invested in the Company Stock Fund and shall remain so invested until distributed; provided, however, that, effective for periods on and after January 1, 2004, an eligible Participant may elect to change the allocation of the balance of his Employer Account attributable to such contributions among the Investment Funds (other than the Loan Fund) then maintained in accordance with subsection 6.1. Contributions made by or for a Participant during any period in which no election is on file with the Administration Committee (other than Employer Contributions made after January 1, 1996) shall be invested under a fixed income or similar fund then maintained under the Plan. Notwithstanding any provision of this subsection 6.2 to the contrary, the Administration Committee may restrict or prohibit investment fund changes as it deems appropriate or desirable from time to time in the administration of the Plan.

6.3. Voluntary Insurance Coverage for Participants. Prior to January 1, 1992, an eligible Participant could elect to have part of his Employer Account balance invested in life insurance or annuity policies on his life (“Policies”). Effective January 1, 1992, such elections were no longer permitted and no new contributions were permitted to be applied towards payment of premiums on Policies acquired prior to that date. In accordance with the provisions of the Plan as in effect prior to the Effective Date, Participants were permitted to elect to continue any such Policy on a paid-up basis or surrender the policy for its then terminal value and to invest the proceeds of such surrender in one or more of the Investment Funds then maintained under the Plan. Consistent with those provisions, any Participant who elected to convert to a paid-up Policy in accordance with the provisions of the Plan as in effect prior to the Effective Date and who has not previously surrendered such Policy, may elect to have such Policy surrendered for its then terminal value, if its terms so provide, as of the last day of any Plan Year and to have the proceeds of such surrender invested in one or more of the Investment Funds then maintained under the Plan in accordance with paragraph 6.2. The proceeds of or benefits under any Policy shall be applied for the benefit of the Participant to whose Account the premiums for the Policies providing such benefits were charged, or for the benefit of his Beneficiary (as defined in subsection 11.5).

SECTION 7

Plan Accounting

7.1. Participant’s Accounts. The Administration Committee shall maintain the following “Accounts” in the name of each Participant and such additional Accounts (if any) as the Administration Committee may determine from time to time:

	(a)		an “Employer Account,” which shall reflect Employer Contributions (and forfeitures allocated to the Participant under the terms of the Plan), and the income, losses, appreciation and depreciation attributable thereto;

	(b)		an “After-Tax Account,” which shall reflect the Participant’s After-Tax Contributions, if any, and the income, losses, appreciation and depreciation attributable thereto;

	(c)		a “Before-Tax Account,” which shall reflect the Before-Tax Contributions, if any, made for the Participant, and the income, losses, appreciation and depreciation attributable thereto;

	(d)		a “Matching Account,” which shall reflect the Matching Contributions, if any, made for the Participant, and the income, losses, appreciation and depreciation attributable thereto;

	(e)		a “Qualified Matching Account,” which shall reflect the Qualified Matching Contributions, if any, made for the Participant, and the income, losses, appreciation and depreciation attributable thereto;

	(f)		a “Qualified Nonelective Account,” which shall reflect the Qualified Nonelective Contributions, if any, allocated to the Participant and the income, losses, appreciation and depreciation attributable thereto;

	(g)		a “QVEC Account,” which shall reflect the deductible voluntary contributions made by the Participant under the provisions of the Plan as in effect before January 1, 1987, and the income losses, appreciation and depreciation attributable thereto; and

	(h)		a “Rollover Account” which shall reflect Rollover Contributions, if any, made by the Participant and the income, losses, appreciation and depreciation attributable thereto.

			The Accounts provided for in this subsection 7.1 shall be for accounting purposes only.

7.2. Adjustment of Participants’ Accounts. The Company has entered into a service contract with a third party to perform certain recordkeeping services for the Plan pursuant to which account valuations and other services shall be provided with respect to Participant Accounts. As of each Accounting Date, the Accounts of each Participant shall be adjusted in accordance with uniform and nondiscriminatory procedures established by the recordkeeper and approved by the Administration Committee, to reflect all contributions, transfers, distributions, loan disbursements and repayments, fees, expenses and other amounts charged to Participants’ Accounts and the investment returns of the Investment Funds in which such Participants’ Accounts are invested.

7.3. Allocation and Crediting of Contributions and Forfeitures. Subject to the provisions of Section 8, contributions shall be allocated and credited as follows:

	(a)		After-Tax, Before-Tax, Matching, Qualified Matching, Qualified Nonelective and Rollover Contributions made by or on behalf of a Participant shall be credited to that Participant’s appropriate Accounts as soon as practicable after they are transmitted to the Trustee.

	(b)		As of the last day of each calendar quarter beginning before January 1, 2005, each Employer’s Employer Contribution for each Business Unit for that quarter, if any, shall be allocated among and credited to the Employer Accounts of all Participants within that Business Unit who meet the requirements of subsection 2.1 on the last day of that quarter (including Participants who were on Employer-approved leaves of absence or on layoff status on the last day of that quarter), and

			Participants who were transferred to employment with another Business Unit, Employer or a Related Company during that quarter or whose Termination Date occurred under paragraph 9.3(a), (b) or (c) during that quarter (provided that each such Participant met the requirements of paragraph 2.1(b) on the date immediately preceding his leave of absence, transfer or termination), in the same ratio that each such Participant’s Eligible Compensation from that Employer during that quarter bears to the total Eligible Compensation paid by that Employer during that quarter to all Participants within the applicable Business Unit who are eligible for an allocation under this paragraph 7.3(b).

	(c)		As of the last day of each Plan Year beginning on or after January 1, 2005 and before January 1, 2009, each Employer’s Employer Contribution that is determined and made by reference to a Business Unit for that year, if any, shall be allocated among and credited to the Employer Accounts of all Participants within that Business Unit who meet the requirements of subsection 2.1 on the last day of that year (including Participants who were on Employer-approved leaves of absence or on layoff status on the last day of that year), and Participants who were transferred to employment with another Business Unit, Employer or a Related Company during that year or whose Termination Date occurred under paragraph 9.3(a), (b) or (c) during that year (provided that each such Participant met the requirements of paragraph 2.1(b) on the date immediately preceding his leave of absence, transfer or termination), in the same ratio that each such Participant’s Eligible Compensation from that Employer during that Plan Year bears to the total Eligible Compensation paid by that Employer during that Plan Year to all Participants within the applicable Business Unit who are eligible for an allocation under this paragraph 7.3(c).

	(d)		On and after July 1, 2008, each Employer’s non-discretionary Employer Contribution that is made under Section 5.1 for that year shall be be made and allocated as soon as reasonably practicable after the end of each payroll period to the Employer Accounts of those Participants employed during such payroll period.

	(e)		Employer Contributions under Section 5.7 shall be made and allocated as soon as reasonably practicable after the end of each payroll period to the Employer Accounts of those Transition A Participants and Transition B Participants employed during such payroll period.

For purposes of Section 8, Employer Contributions for any Plan Year (or portion thereof) will be considered to have been made on the last day of that year, regardless of when paid to the Trustee. Notwithstanding any provisions of this Section 7 to the contrary, unless the Administration Committee establishes uniform rules to the contrary, contributions made to the Plan shall share in the income, gains and losses of the Investment Funds only when actually made to the Trustee.

7.4. Statement of Plan Interest. As soon as practicable after the last day of each Plan Year quarter and at such other intervals, if any, as the Administration Committee may decide, the Administration Committee shall provide each Participant with a statement reflecting the balances of his Account and such other information as is required by Section 105(a)(2) of ERISA.

7.5. Correction of Error. In the event of an error in the adjustment of a Participant’s Accounts, the Administration Committee, in its sole discretion, may correct such error by either crediting or charging the adjustment required to make such correction to or against income and expenses of the Trust for the Plan Year in which the correction is made, or the Employers may make an additional contribution to permit correction of the error. Except as provided in this subsection 7.5 or as otherwise determined by the Administration Committee, the Accounts of other Participants shall not be readjusted on account of such error.

SECTION 8

Limitations on Compensation, Contributions and Allocations

8.1. Reduction of Contribution Rates. The Administration Committee may (i) unilaterally modify or revoke any Before-Tax or After-Tax Contribution election made by a Participant pursuant to subsections 4.1 or 4.2 to conform the operation of the Plan to Sections 401(k)(3), 401(m)(2) and 415 of the Code, (ii) reduce (to zero if

necessary) the amount of Matching, Qualified Matching, Qualified Nonelective Contributions or Employer Contributions that would otherwise be made on behalf of a Participant pursuant to Article 5 to conform the operation of the Plan to Section 415 of the Code, or (iii) reduce (to zero if necessary) the level of Matching Contributions to be made on behalf of Highly Compensated Participants pursuant to Section 5 to conform the operation of the Plan to Section 401(m)(2) of the Code.

8.2. Compensation for Limitation/Testing Purposes. “Compensation” for purposes of this Section 8 shall include:

	(a)		the amount shown as “wages” for purposes of federal income tax withholding on any Form W-2 issued by an Employer or Related Company to the Participant for the Plan Year but excluding, solely for purposes of subsections 8.7 and 8.9, any severance payments paid upon termination of employment; plus

	(b)		the amount of any Before Tax Contributions and any other elective contributions made on the Participant’s behalf for the Plan Year to a plan sponsored by an Employer or Related Company that are not includable in the Participant’s gross income pursuant to Section 125, 402(a)(8) or, for Plan Years beginning on and after January 1, 2001, Section 132(f)(4) of the Code,

up to a maximum limit as may be permitted for any Plan Year under Section 401(a)(17) of the Code, taking into account any required proration of such amount under applicable Treasury regulations on account of a short Plan Year. Effective for Plan Years beginning after December 31, 2001, the amount of Compensation that may be taken into account under Section 401(a)(17) of the Code is $200,000, as adjusted for cost-of-living as described in subsection 4.7 of the Plan.

8.3. Limitations on Annual Additions. Except to the extent permitted under paragraph 4.1(b) of the Plan and section 414(v) of the Code, and notwithstanding any other provision of the Plan to the contrary, a Participant’s Annual Additions (as defined below) for any Plan Year shall not exceed an amount equal to the lesser of:

	(a)		$40,000, as adjusted for increases in the cost-of-living under section 415(d) of the Code; or

	(b)		100% of the Participant’s Compensation for that Plan Year (for Plan Years beginning before January 1, 1998, excluding amounts described in clause (b) of subsection 8.2), calculated as if each Section 415 Affiliate (described below) were a Related Company,

reduced by any Annual Additions for the Participant for the Plan Year under any other defined contribution plan of an Employer or a Related Company or Section 415 Affiliate, provided that if any other such plan has a similar provision, the reduction shall be pro rata. The term “Annual Additions” means, with respect to any Participant for any Plan Year, the sum of all contributions (excluding Rollover Contributions and catch-up Before-Tax Contributions described in paragraph 4.1(b)) and forfeitures allocated to a Participant’s Accounts under the Plan for such year pursuant to subsections 7.3 and 11.7, excluding Before-Tax Contributions that are distributed as excess deferrals in accordance with subsection 8.6, but including any Before-Tax, After-Tax or Matching Contributions (the latter even if forfeited) treated as excess contributions or excess aggregate contributions under subsections 8.8, 8.10 and 8.11. The term Annual Additions shall also include employer contributions allocated for a Plan Year to any individual medical account of a Participant (as defined in Section 415(1) of the Code) under a defined benefit plan and any amount allocated for a Plan Year to the separate account of a Participant for payment of post-retirement medical benefits under a funded welfare benefit plan (as described in Section 419A(d)(2) of the Code), which is maintained by an Employer or a Related Company or a Section 415 Affiliate. “Section 415 Affiliate” means any entity that would be a Related Company if the ownership test of Section 414 of the Code was “more than 50%” rather than “at least 80%.”

8.4. Excess Annual Additions. If, as a result of the allocation of forfeitures, a reasonable error in estimating a Participant’s Compensation or such other mitigating circumstances as the Commissioner of Internal Revenue shall prescribe, the Annual Additions for a Participant for a Plan Year exceed the limitations set forth in subsection 8.3, the excess amounts shall be treated, as necessary, in accordance with Treas. Reg. § 1.415-6(b)(6)(i), after any After-Tax Contributions and then any Before-Tax Contributions are first returned in accordance with

Treas. Reg. § 1.415-6(b)(6)(iv). Any Before-Tax or After-Tax Contributions returned to the Participant in accordance with this subsection 8.4 shall be disregarded for purposes of subsections 8.6, 8.7, 8.9 and 8.11.

8.5. Combined Plan Limitation. Prior to January 1, 2000, if a Participant also participates in any defined benefit plan (as defined in Section 415(k) of the Code) maintained by an Employer or a Related Company or Section 415 Affiliate, the aggregate benefits payable to, or on account of, the Participant under such plan together with this Plan shall be determined in a manner consistent with Section 415(e) of the Code. The benefit provided for the Participant under the defined benefit plan shall be adjusted to the extent necessary so that the sum of the “defined benefit fraction” and the “defined contribution fraction” (as such terms are defined in Section 415(e) of the Code and applicable regulations thereunder) calculated with regard to such Participant does not exceed 1.0. For purposes of this subsection 8.5, all qualified defined benefit plans (whether or not terminated) of the Employers, Related Companies and Section 415 Affiliates shall be treated as one defined benefit plan. The provisions of this subsection 8.5 do not apply for Plan Years beginning on or after January 1, 2000.

8.6. Section 402(g) Limitation. In no event shall the Before-Tax Contributions for a Participant under the Plan (together with elective deferrals under any other cash-or-deferred arrangement maintained by an Employer or a Related Company) for any taxable year exceed the maximum amount permitted for such year under Section 402(g) of the Code (including, to the extent applicable, the amount permitted for such year pursuant to subsection 402(g)(1)(C) with respect to catch-up Before-Tax Contributions). If during any taxable year a Participant is also a participant in any other cash-or-deferred arrangement, and if his elective deferrals made under such other arrangements together with his Before-Tax Contributions and, if applicable, his catch-up Before Tax Contributions exceed the maximum amount permitted for the Participant for that year under Section 402(g) of the Code, the following provisions shall apply:

	(a)		The Participant, not later than March 1 following the close of such taxable year, may request the Administration Committee to direct the Trustee to distribute all or a portion of such excess to him, together with any gains or losses allocable thereto for that Plan Year and, in the case of distributions in Plan Years beginning on or after January 1, 2007, for the period from the close of such Plan Year to a date that is no more than seven days before the date of distribution.

	(b)		Such gains and losses shall be determined in accordance with any reasonable method adopted by the Administration Committee that complies with ▇▇▇▇▇. Reg, Section 1.402(g)-1(e)(5) and is used consistently for all Participants and all corrective distributions for such year.

	(c)		Any such request shall be in writing and shall include adequate proof of the existence of such excess, as determined by the Administration Committee in its sole discretion. If the Administration Committee is so notified, such excess amount shall be distributed to the Participant no later than the April 15 following the close of the Participant’s taxable year.

	(d)		If the applicable limitation for a Plan Year is exceeded with respect to this Plan alone, or this Plan and another plan or plans of the Employers and Related Companies, the Administration Committee shall direct such excess Before-Tax Contributions (with allocable gains or losses for that Plan Year and, in the case of distributions in Plan Years beginning on or after January 1, 2007, for the period from the close of such Plan Year to a date that is no more than seven days before the date of distribution) to be distributed to the Participant as soon as practicable after the Administration Committee is notified of the excess deferrals by the Company, an Employer or the Participant, or otherwise discovers the error (but no later than the April 15 following the close of the Participant’s taxable year).

Notwithstanding the foregoing provisions of this subsection 8.6, the dollar amount of any distribution due hereunder shall be reduced by the dollar amount of any Before-Tax Contributions previously distributed to the same Participant pursuant to subsection 8.8, provided, however, that for purposes of subsections 8.3 and 8.7, the correction under this subsection 8.6 shall be deemed to have occurred before the correction under subsection 8.8.

8.7. Section 401(k)(3) Testing. For any Plan Year, the amount by which the average of the Deferral Percentages (as defined below) of each eligible employee who is Highly Compensated for such Plan Year (the

“Highly Compensated Group Deferral Percentage”) exceeds the average of the Deferral Percentages for such Plan Year of each eligible employee who is not Highly Compensated (the “Non-Highly Compensated Group Deferral Percentage”) for such Plan Year shall be less than or equal to either (i) a factor of 1.25 or (ii) both a factor of 2 and a difference of 2. “Deferral Percentage” for any eligible employee for a Plan Year shall be determined by dividing his Before-Tax Contributions and, to the extent designated by the Administration Committee, his Qualified Matching Contributions or Qualified Nonelective Contributions (or both) for the year by his Compensation for the year, subject to any special rules set forth in applicable Treasury regulations. For purposes of this subsection 8.7, the provisions of Code Section 410(k)(3) and Treas. Reg. § 1.401(k)-1(b) are herein incorporated by reference, and any Qualified Matching Contributions and any Qualified Nonelective Contributions used in determining a Participant’s Deferral Percentage shall satisfy the requirements of Treas. Reg. Section 1.401(k)-2(a)(6). Amounts that are catch-up Before-Tax Contributions made in accordance with paragraph 4.1(b) of the Plan and Section 414(v) of the Code shall be disregarded for purposes of this subsection 8.7.

8.8. Correction Under Section 401(k) Test. In the event that the Highly Compensated Group Deferral Percentage for any Plan Year does not initially satisfy one of the tests referred to in subsection 8.7, the following provisions shall apply:

(a)

Excess Contributions (as defined below) shall be distributed to the Highly Compensated Participants to whose accounts such Excess Contributions were allocated for such Plan Year, together with any gains or losses allocable thereto for that Plan Year and (with respect to Plan Years before January 1, 2008) for the period from the close of such Plan Year to a date that is no more than seven days before the date of distribution, except to the extent that any such Excess Contributions are classified as catch-up Before-Tax contributions. Excess contributions shall be allocated to the Highly Compensated Participants with the largest amount of Before-Tax Contributions taken into account under Section 8.7 for the Plan Year in which the excess arose, beginning with the Highly Compensated Participant with the largest amount of such Before Tax Contributions and continuing in descending order until all the Excess Contributions have been allocated. To the extent that a Highly Compensated Participant is eligible to make catch-up Before-Tax Contributions for the Plan Year in which the Excess Contributions arose but has not reached the limit on such contributions in effect under the Plan for such Plan Year, Excess Contributions allocated to such Highly Compensated Participant shall be considered catch-up Before-Tax Contributions and shall not be treated as Excess Contributions.

(b)

The term “Excess Contributions” shall mean, with respect to any Plan Year, the excess of;

	(i)		the aggregate amount of Before-Tax Contributions actually taken into account in computing the Highly Compensated Group Deferral Percentage for such Plan Year, over

	(ii)		the maximum aggregate amount of Before-Tax Contributions permitted under the tests set forth in subsection 8.7 for such Plan Years (determined by hypothetically reducing the Before-Tax Contributions made on behalf of Highly Compensated Participants for such year in order of their actual Deferral Percentages, beginning with the highest of such percentages).

(c)

The gain or loss allocable to Excess Contributions shall be determined in accordance with any reasonable method adopted by the Committee that complies with ▇▇▇▇▇. Reg. Section 1.401(k)-2(b)(iv)(B) and is used consistently for all Participants and all corrective distributions for such year.

The amounts to be distributed to any Participant pursuant to this subsection 8.8 shall be reduced by the amount of any Before-Tax Contributions distributed to him for the taxable year ending with or within such Plan Year pursuant to subsection 8.6. The Administration Committee shall take such actions and cause any distribution to be made no later than the close of the Plan Year following the Plan Year for which the Excess Contributions were made.

8.9. Code Section 401(m)(2) Testing. For any Plan Year, the amount by which the average of the Contribution Percentages (as defined below) of each eligible employee who is Highly Compensated for such Plan Year (the “Highly Compensated Group Contribution Percentage”) exceeds the average of the Contribution Percentages of each eligible employee who is not Highly Compensated (the “Non-Highly Compensated Group Contribution Percentage”) for such Plan Year shall be less than or equal to either (i) a factor of 1.25 or (ii) both a factor of 2 and a difference of 2. The “Contribution Percentage” for any eligible employee for a Plan Year shall be determined by dividing his After-Tax Contributions and Matching Contributions (excluding Matching Contributions forfeited in accordance with subsection 5.6) and, to the extent designated by the Administration Committee, his Qualified Matching contributions or Qualified Nonelective Contributions (or both) for such year by his Compensation for the year, subject to any special rules set forth in the applicable Treasury regulations. The provisions of Code Section 401(m)(2) and Treas. Reg. § 1.401(m)-1(b) are herein incorporated by reference, and any Qualified Matching Contribution or Qualified Nonelective Contribution used in determining a Participant’s Contribution Percentage shall satisfy the requirements of Treas. Reg. Section 1.401(m)-2(a)(6).

8.10. Correction Under Section 401(m) Test. In the event that the Highly Compensated Group Contribution Percentage for any Plan Year does not initially satisfy one of the tests referred to in subsection 8.9, the following provisions shall apply:

	(a)		Excess Aggregate Contributions (as defined below) shall be forfeited, if forfeitable, or if not forfeitable, distributed to the Highly Compensated Participants to whose accounts such Excess Aggregate Contributions were allocated for such Plan Year, together with any gains or losses allocable thereto for that Plan Year and (with respect to Plan years before January 1, 2008) for the period from the close of such Plan Year to a date that is no more than seven days before the date of distribution. Excess Aggregate Contributions shall be allocated to the Highly Compensated Participants with the largest amount of After-Tax and Matching contributions taken into account under the tests in Section 8.9 for the Plan Year in which the excess arose, beginning with the Highly Compensated Participant with the largest amount of such contributions and continuing in descending order until all the Excess Aggregate Contributions have been allocated.

	(b)		The term “Excess Aggregate Contributions” shall mean, with respect to any Plan Year, the excess of:

	(i)		the aggregate amount of After-Tax and Matching Contributions actually taken into account in computing the Highly Compensated Group Contribution Percentage for such Plan Year, over

	(ii)		the maximum aggregate amount of After-Tax and Matching Contributions permitted under the tests set forth in subsection 8.9 for such Plan Year (determined by hypothetically reducing the contributions made on behalf of Highly Compensated Participants in order of their Contribution Percentage beginning with the highest of such percentages).

(c)

The gain or loss allocable to Excess Aggregate Contributions shall be determined in accordance with any reasonable method adopted by the Administration Committee that complies with Treas. Reg. Section 1.401(m)-2(b)(2)(iv)(B) and is used consistently for all Participants and all corrective distributions for such year.

(d)

Excess Aggregate Contributions shall be deemed attributable to, first, any unmatched After-Tax Contributions, then (if necessary) a proportionate share of matched After-Tax Contributions and the Matching Contributions allocable thereto, and last, any remaining Matching Contributions.

The Administration Committee shall make any necessary distribution no later than the close of the Plan Year following the Plan Year in which such Excess Aggregate Contributions were contributed. Matching Contributions that are Excess Aggregate Contributions and are not yet vested in accordance with subsection 9.1 shall be forfeited as of the end of the Plan Year following the Plan Year in which the Excess Aggregate Contributions arose and treated in the same manner as any other forfeiture under the Plan.

8.11. Forfeiture of Orphan Matching Contributions. Matching Contributions attributable to excess Before-Tax or After-Tax Contributions distributed in accordance with subsections 8.6, 8.8 or 8.10 shall be forfeited as of the end of the Plan Year to which such corrective distributions relate and treated in the same manner as any other forfeiture under the Plan.

8.12. Highly Compensated. An employee or Participant shall be “Highly Compensated” for any Plan Year if he:

(a)

is a 5 percent owner of an Employer or a Related Company at any time during that year or the prior Plan Year; or

(b)

for the preceding Plan Year, received Compensation in excess of $80,000 (indexed for cost-of-living adjustments under Section 415(d) of the Code).

8.13. Separate Testing of Early Eligible Group. Notwithstanding the foregoing provisions of this Section 8, for any Plan Year the Administration Committee may elect, in accordance with applicable Treasury regulations, to apply the tests set forth in subsections 8.8 and 8.10 separately with respect to all eligible employees who would not have been eligible to participate in the Plan for that Plan Year had the Plan utilized the maximum age and service requirements for eligibility permitted by the Code.

SECTION 9

Vesting and Termination Dates

9.1. Determination of Vested Interest. A Participant shall at all times have a nonforfeitable interest in his Before-Tax Account, After-Tax Account, Rollover Account, Qualified Matching Account, Qualified Nonelective Account and QVEC Account.

Years of Service	Vested Percentage
fewer than 2		0	%
2 or more		100	%

provided, however, that any Participant whose vested percentage would be greater under the vesting schedule in effect immediately prior to July 1, 2008, shall have his vested percentage determined under that prior vesting schedule.

If a Participant is employed by an Employer or Related Company after December 31, 2006 but not after June 30, 2008, such Participant’s interest in his Matching Account and his Employer Account shall be fully vested and nonforfeitable in accordance with the following schedule:


Years of Service	Vested Percentage
fewer than 1		0	%
1 but less than 3		33	%
3 but less than 5		66	%
5 or more		100	%

If a Participant is not employed by an Employer or Related Company after December 31, 2006:

(a)

his nonforfeitable interest in his Matching Account shall be determined in accordance with the schedule above; and

(b)

his nonforfeitable interest in his Employer Account shall be determined in accordance with the following schedule:


Years of Service	Vested Percentage
fewer than 1		0	%
1 but less than 5		33	%
5 or more years		100	%

Notwithstanding the foregoing provisions of this subsection 9.1, a Participant hired by the Company or a Related Company prior to January 1, 1996, shall be fully vested in his Employer Account without regard to the schedules set forth above.

9.2. Accelerated Vesting. Notwithstanding the foregoing provisions of this Section 9, a Participant shall have a fully vested, nonforfeitable interest in all his Accounts when he attains age 65, dies or becomes disabled within the meaning of paragraph 9.3(b) while employed by an Employer or a Related Company. In addition, in the event of the Plan’s termination (in accordance with subsection 13.2) or partial termination (as determined under applicable law and regulations) or the complete discontinuance of Employer and Matching Contributions to the Plan, each affected Participant shall have a fully vested, nonforfeitable interest in all his Accounts.

9.3. Termination Dates. A Participant’s “Termination Date” shall be the date on which his employment with the Employers and the Related Companies is terminated because of the first to occur of the following events:

	(a)		Retirement. The Participant retires or is retired from the employ of the Employers and Related Companies and is entitled to retirement income as defined and determined under the terms of the A. M. Castle & Co. Salaried Employees Pension Plan or any other defined benefit pension plan sponsored by the Company, or, if his Employer is not a sponsor of any defined benefit pension plan, would be entitled to such a payment if his Employer maintained the A. M. Castle & Co. Salaried Employees Pension Plan.

	(b)		Disability. The Participant leaves the employ of the Employers and Related Companies at any age because of disability. A Participant will be considered disabled for purposes of the Plan if he is awarded disability insurance benefits under the Social Security Act, if he is entitled to a pension for permanent incapacity under the terms of the A. M. Castle & Co. Hourly Employees Pension Plan, or would be entitled to such a pension if his Employer maintained that plan, or if he is entitled to a benefit under a long term disability salary continuation plan maintained by his Employer, or would be entitled to a benefit under such a plan if he met the minimum service requirements for eligibility under the plan.

	(c)		Death. The Participant’s death.

	(d)		Resignation or Dismissal. The Participant resigns or is dismissed from the employ of the Employers and the Related Companies before retirement or disability as described in paragraph (a) or (b) above.

9.4. Distribution Upon Separation. Notwithstanding any other provision of the Plan to the contrary, a Participant may not commence distribution of his Before-Tax Account, Qualified Matching Account or Qualified Nonelective Account pursuant to Section 11 unless:

(a)

for periods prior to January 1, 2002, the Participant has had a “separation from service” (within the meaning of Section 401(k)(2) of the Code as in effect prior to January 1, 2002), or the requirements of Section 401(k)(10) of the Code as then in effect are satisfied; and

(b)

for periods after December 31, 2001, the Participant has incurred a separation from employment (within the meaning of Section 401(k) of the Code as amended by the Economic Growth and Tax

Relief Reconciliation Act of 2001), including a separation from employment that occurred before January 1, 2002.

SECTION 10

Loans and Withdrawals of
Contributions While Employed

10.1. Loans to Participants. The Administration Committee, upon request by a Participant who is an employee of an Employer or Related Company or who is a “party in interest” with respect to the Plan (as such term is defined in Section 3(14) of ERISA) in such form as the Administration Committee may require, may authorize a loan to be made to the Participant from his vested interest in the Trust Fund, excluding any amount in his QVEC Account, subject to the following:

(a)

No loan shall be made to a Participant if, immediately after such loan, the sum of the outstanding balances (including principal and interest) of all loans made to such Participant under this Plan and under any other qualified retirement plans maintained by the Employers and the Related Companies does not exceed the lesser of (i) $50,000, reduced by the excess, if any, of

	(A)		the highest outstanding balance of all loans to the Participant from the plans during the one-year period ending on the day immediately before the date on which the loan is made, over

	(B)		the outstanding balance of loans from the plans to the Participant on the date on which such loan is made; or the greater of $10,000 or one-half of the aggregate vested interest of the Participant under all such plans;

or (ii) the greater of one-half of the aggregate vested interest of the Participant under all such plans or $10,000; and no loan shall be made to a Participant if the aggregate amount of that loan and the outstanding balance of any other loans to the Participant from the Plan would exceed one-half of the total vested balance of the Participant’s Accounts under the Plan as of the date the loan is made.

	(b)		Subject to the limitations of paragraph (a) next above, no loan shall be made to a Participant unless it is for an amount which is at least equal to $1,000. A Participant may not have more than 2 loans outstanding at any time.

	(c)		Each such loan shall provide for:

	(i)		a reasonable repayment period of not more than five years from the date of the loan except in the case of a loan on or after January 1, 2000 used to acquire the Participant’s principal residence, in which case, the repayment period may be up to 10 years but not beyond the Participant’s normal retirement age, within the meaning of Section 411 (a)(8) of the Code;

	(ii)		a reasonable rate of interest;

	(iii)		substantially equal payments of principal and interest over the term of the loan no less frequently than quarterly;

	(iv)		such other terms and conditions as the Administration Committee shall determine; and

shall be evidenced by an agreement set forth in writing or in such other form as the Administration Committee may provide from time to time in accordance with uniform procedures consistently applied. Notwithstanding any provision of this Section 10 to the contrary, negotiation of a loan

check shall evidence the Participant’s acceptance of and consent to be bound by the terms and conditions of such loan.

	(d)		Promissory notes or other indicia of indebtedness shall be held by the Trustee under the Loan Fund, unless delegated by the Trustee to the Administration Committee.

	(e)		Payments of principal and interest to the Trustee with respect to any loan to a Participant:

	(i)		shall reduce the outstanding balance with respect to that loan;

	(ii)		shall reduce the balance of the Participant’s Loan Fund;

	(iii)		shall be credited to the Participant’s appropriate Account (other than his QVEC Account); and

	(iv)		shall be invested in the Investment Funds in accordance with his most recent investment election.

	(f)		A Participant’s obligation to repay a loan (or loans) from the Plan shall be secured by the portion of the Participant’s vested interest in the Plan equal to the outstanding balance of the loan plus accrued but unpaid interest as of any date on or after the loan is made; provided, however, that not more than 50% of the Participant’s vested account balance, determined immediately after origination of the loan, shall be taken into account as security for the loan.

	(g)		During the Participant’s employment with the Employers or Related Companies, loan repayments will be made by payroll deductions. After termination of employment or during any other period when payroll deduction is not possible or is not permitted under applicable law, repayment will be made by personal check.

	(h)		The loan may be prepaid in full at any time without penalty.

	(i)		Except in the case of a Participant who is a party in interest to the Plan, any outstanding loan of a Participant shall become immediately due and payable upon his Termination Date. Notwithstanding any other provision of the Plan to contrary, if the outstanding balance of principal and interest on any loan is not paid at the expiration of its term or upon acceleration in accordance with the preceding sentence, a default shall occur and the Trustee shall apply all or a portion of the Participant’s vested interest in the Plan in satisfaction of such outstanding obligation, after all other adjustments required under the Plan have been made, but before any payment or distribution to any person pursuant to the provisions of Section 11.

	(j)		The Administration Committee shall establish uniform procedures for applying for a loan, evaluating loan applications, and setting reasonable rates of interest.

10.2. Withdrawals During Employment. Subject to the following provisions of this subsection 10.2, a Participant whose Termination Date has not yet occurred may elect to withdraw all or part of his interest in the Investment Funds (other than the Loan Fund) in such proportion as he shall direct and upon such prior notice as the Administration Committee may require, as provided and in the order set forth below:

	(a)		up to 100% of the After-Tax Contributions (excluding any earnings thereon) made by the Participant prior to January 1, 1987;

	(b)		up to 100% of his After-Tax Account (excluding pre- 1987 contributions);

	(c)		up to 100% of his QVEC Account (including earnings thereon);

	(d)		up to 100% of his Rollover Account (including earnings thereon);

	(e)		in the event of the Participant’s attainment of age 59 1/2, up to 100% of the vested balances in all of his Accounts;

	(f)		in the event of a Hardship, up to 100% of the vested portion of, first, his Employer Account, and then his Matching Account;

	(g)		in the event of a Hardship, up to 100% of the Before-Tax Contributions credited to his Before-Tax Account (excluding any earnings thereon); and

	(h)		in the event a Participant is ordered or called to active military duty for a period in excess of 179 days and qualifies for a “qualified reservist distribution” under Section 79(t)(2)(G)(iii), up to 100% of the vested balances in all of his Accounts.

No portion of a Participant’s Qualified Matching Account or Qualified Nonelective Account may be withdrawn prior to the Participant’s attainment of age 59¹/2.

10.3. Hardship Withdrawals. A withdrawal will not be considered to be made on account of “Hardship” unless the following requirements are met:

(a)

The withdrawal is requested because of an immediate and heavy financial need of the Participant, and will be so deemed if the Participant represents that the withdrawal is made on account of:

	(i)		expenses for (or necessary to obtain) medical care incurred by the Participant, his spouse, children or dependents (as defined in Section 152, and, for taxable years beginning on or after January 1, 2005, without regard to Section 152(b)(1), (b)(2) and (d)(1)(B)), or the Participant’s primary beneficiary under the Plan that would be deductible under Section 213(d) (determined without regard to whether the expenses exceed 7.5% of adjusted gross income);

	(ii)		costs directly related to the purchase (excluding mortgage payments) of a principal residence of the Participant;

	(iii)		payment of tuition and related educational fees for the next 12 months of post-secondary education for the Participant, his spouse, children or dependents (as defined in Section 152, and, for taxable years beginning on or after January 1, 2005, without regard to Section 152(b)(1), (b)(2) and (d)(1)(B) or the Participant’s primary beneficiary under the Plan;

	(iv)		the need to prevent the eviction of the Participant from his principal residence or foreclosure on the mortgage of the Participant’s principal residence;

	(v)		payment for burial or funeral expenses for the Participant’s deceased parent, spouse, children, dependents (as defined in Section 152 without regard to Section 152(b)(1), (b)(2) and 152(d)(1)(B)) or the Participant’s primary beneficiary;

	(vi)		expenses for the repair of damage to the Participant’s principal residence that would qualify for the casualty deduction under Section 165 (determined without regard to whether the loss exceeds ten percent of adjusted gross income); or

	(vii)		any other circumstances of immediate and heavy financial need identified as such in revenue rulings, notices or other documents of the Internal Revenue Service of general applicability.

(b)

The withdrawal must also be necessary to satisfy the immediate and heavy financial need of the Participant. The withdrawal will be deemed necessary to satisfy such need if:

	(i)		the Participant represents that the withdrawal is not in excess of the amount of the immediate and heavy financial need (taking into account any applicable income or penalty taxes resulting from the withdrawal);

	(ii)		the Participant has obtained all distributions (other than Hardship distributions under this subsection 10.3) and all nontaxable loans currently available under the Plan and all other plans maintained by the Employers and Related Companies; and

	(iii)		Before-Tax Contributions, After-Tax Contributions and Matching Contributions by or on behalf of the Participant shall be suspended for a period of six months after the Participant makes a Hardship withdrawal under this subsection 10.3, and the Participant shall be prohibited from making any contributions for the same period to any other deferred compensation plan (whether or not qualified), stock option, stock purchase or similar plan maintained by an Employer or Related Company..

SECTION 11

Distributions

11.1. Distributions to Participants After Termination of Employment. If a Termination Date occurs with respect to a Participant, the vested portions of his Accounts and all Policies issued on his life, or the proceeds thereof, shall be distributed in accordance with the following provisions of this Section 11; provided, however, that if the value of the vested portions of the Participant’s Accounts (including any loans outstanding on his Termination Date) does not exceed $1,000 ($5,000 for periods prior to January 1, 2006), such vested portions shall be distributed to or on behalf of the Participant as soon as practicable after such Termination Date. Notwithstanding the preceding sentence, during the period beginning March 28, 2005, and ending December 31, 2005, if the value of such vested Accounts exceeds $1,000 but does not exceed $5,000, and the Participant does not elect to have such vested Accounts paid directly to him or to an eligible retirement plan specified by him in a direct rollover, the Administration Committee shall distribute such vested portions in a direct rollover to an individual retirement plan designated by the Administration Committee for the benefit of the Participant.

11.2. Forms of Benefit Payments. If a Termination Date occurs with respect to a Participant, subject to the provisions of subsections 11.1 and 11.4, the vested balance in his Accounts as of any Accounting Date coincident with or following his Termination Date he (or his Beneficiary) elects (after all adjustments then required under the Plan have been made) and all Policies issued on his life, or the proceeds thereof, shall be distributed to the Participant or, in the event of his death, his Beneficiary, by one of the following methods which he (or his Beneficiary) elects:

	(a)		By payment in a lump sum. OR

	(b)		By payment in a series of substantially equal monthly installments in an amount not less than $100 per month over a period not extending beyond the joint life expectancy of the Participant and his spouse (if any), or the life expectancy of his Beneficiary, if applicable, determined as of the date payments commence. OR

	(c)		By purchase from the Insurer (defined below) and distribution to him of an annuity, subject to the following:

	(i)		Methods of payment shall be limited to an annuity payable (A) for life, or (B) for life and a period of fifteen years certain (or, if less, a period certain which does not exceed the Participant’s (or Beneficiary’s) life expectancy as of the date benefits commence).

	(ii)		An annuity benefit will be of the fixed type under which annuity payments will commence as of a date not later than the date required under subsection 11.4. The premium paid to the Insurer for any annuity will be charged to the Participant’s Accounts when paid. The Administration Committee shall cause the annuity to be delivered to the

person or persons entitled to payments under it in a nontransferable form and in a form that is noncommutable. OR

(d)

In the case of a Policy purchased on the life of such Participant pursuant to subsection 6.3, by assignment of such Policy to the Participant or by surrender of such Policy for cash and application of the cash proceeds for the benefit of the Participant or Beneficiary by either of the methods specified in paragraphs (a) and (b) next above.

The term “Insurer” means any life insurance company issuing Policies held by the Trustee under the Plan or issuing an investment-type annuity contract under which a portion of the Fixed Income Fund is invested or any life insurance company authorized to do business in the State of Illinois and selected by the Administration Committee. If a Participant dies before receiving all of his benefits payable in accordance with this subsection 11.2, any remaining portion of his Account balances shall be paid, as soon as practicable, to or for the benefit of his Beneficiary in one of the methods described in this subsection 11.2 as is selected by the Beneficiary. A Participant’s interest in the Company Stock Fund shall be distributed to him (or in the event of his death, his Beneficiary) in the form of Common Stock, unless such Participant (or Beneficiary) elects to receive his entire interest in the Company Stock Fund in cash, subject to such valuation procedures as the Administration Committee in its discretion shall establish. The remaining portion of the Participant’s Account shall be distributed in cash. Notwithstanding the foregoing, if a Participant retires under a pension plan sponsored by his Employer and such Participant elects installment payments under paragraph (b) above, prior to the commencement of such installments he shall choose to either (i) transfer his interest in the Company Stock Fund to the other Investment Funds (except the Loan Fund) and have his installments based on his entire Account balance, or (ii) receive his interest in the Company Stock Fund in the form of Common Stock as a partial lump sum payment coincident with the first such installment, and have the remaining portion of his Account distributed in installments in cash.

11.3. Special Rules Governing Annuity Elections. If a married Participant elects distribution in the form of an annuity pursuant to paragraph 11.2(c), the following rules shall apply and shall supersede any other provision of the Plan to the contrary:

(a)

The vested portions of the Participant’s Accounts, shall be used to purchase a nontransferable “Joint and Survivor Annuity” (that is, an immediate annuity payable for the life of the Participant with a survivor annuity payable for the life of his spouse which is not less than 50% of the amount of the annuity payable during the joint lives of the Participant and spouse), unless he elects another form of annuity and, if applicable, a Beneficiary other than his spouse, with the consent of his spouse to such form and Beneficiary, during the 180-day period immediately preceding his Distribution Date. With regard to the election, the Administration Committee shall provide to the Participant no less than 30 days and no more than 90 days (or effective January 1, 2007, 180 days) before the “annuity starting date” a written explanation of:

	(1)		the terms and condition of the Joint and Survivor Annuity,

	(2)		the Participant’s right to make, and the effect of, an election to waive the Joint and Survivor Annuity,

	(3)		the right to the Participant’s spouse to consent to any election to waive the Joint and Survivor Annuity,

	(4)		the right of the Participant to revoke such election, and the effect of such revocation, and

	(5)		the relative values of the various optional forms of benefit payment under the Plan.

Effective for annuity starting dates on or after January 1, 2008, in lieu of a Joint and Survivor Annuity, the Participant shall be permitted to elect an immediate annuity payable for the life of the Participant with a survivor annuity payable for the life of his spouse which is 75% of the amount of the annuity payable during the joint lives of the Participant and spouse (a “Qualified Optional Survivor Annuity”).

	(b)		No consent by the spouse to the election of a form of annuity other than the Joint and Survivor Annuity and, if applicable, Beneficiary other than the spouse shall be effective unless it is in writing, acknowledges the effect of such consent and is witnessed by a Plan representative or a notary public (unless the Administration Committee determines that there is no spouse, that the spouse cannot be located or that consent may be waived because of such other circumstances as regulations or rulings under Code Section 417 set forth).

	(c)		During the period between his election of an annuity and his Distribution Date, no loan may be made to a Participant pursuant to subsection 10.1, no amount may be withdrawn by the Participant pursuant to subsection 10.2 and no amount may be distributed to the Participant pursuant to this Section 11, in any form other than a Joint and Survivor Annuity, without the written consent of the spouse as provided in paragraph (b) of this subsection 11.3.

	(d)		Subject to paragraph (e) below, if the Participant dies during the period between his election of an annuity and his Distribution Date, the vested portions of his Accounts and the proceeds of any Policies on his life shall be paid to his spouse in the form of a straight life annuity as of the Accounting Date coincident with or next following the date the Participant would have attained age 65 or, if the spouse so elects, as soon as practicable after the Accounting Date coincident with or next following his death; provided, however, that a spouse to whom payment is due under this paragraph (d) may elect to have such vested portions, if any, distributed in the form of a lump sum payment.

	(e)		The provisions of paragraph (d) above shall not apply, and distribution upon the death of the Participant shall be made in accordance with subsection 11.2, if the spouse consents to the designation of a Beneficiary other than the spouse in accordance with subsection 11.5 during the period between the Participant’s election of an annuity and his death, and acknowledges that such consent to the Participant’s designation of such Beneficiary constitutes the spouse’s consent to the Participant’s waiver of a qualified preretirement survivor annuity payable to the spouse in accordance with Section 417 of the Code.

	(f)		A Participant may revoke his election pursuant to this subsection 11.3, and may make a new election of any form of distribution permitted under subsection 11.2, at any time and any number of times during the 180-day period immediately preceding his Distribution Date; provided, however, that if the effect of such revocation is to select a distribution form other than a Joint and Survivor Annuity, it shall be ineffective without the written consent of his spouse in accordance with paragraph (b) of this subsection 11.3 to the new form of distribution and, if applicable, a Beneficiary other than the spouse.

	(g)		A spouse’s consent in accordance with paragraph (b) of this subsection 11.3 shall be irrevocable.

11.4. Limits on Commencement and Duration of Distributions. The following distribution rules are intended to conform distributions under the Plan to Sections 401(a)(9) and 401(a)(14) of the Code and applicable regulations thereunder, including the minimum distribution incidental benefit requirement of Code Section 401(a)(G):

	(a)		Unless the Participant elects otherwise, in no event shall distribution commence later than 60 days after the close of the Plan Year in which the latest of the following events occurs: the Participant’s attainment of age 65; the 10th anniversary of the year in which the Participant began participating in the Plan; or the Participant’s Termination Date.

	(b)		Notwithstanding any other provision herein to the contrary, distribution of the Participant’s Accounts shall commence no later than his “Required Beginning Date,” that is, April 1 of the calendar year following the calendar year in which he (i) attains age 70-1/2, or (ii) terminates employment with the Related Companies, whichever is the later; provided, however, that in the case of a Participant who is a 5% or more owner (as described in Section 416 of the Code) during

the Plan Year ending in the calendar year in which he attains age 70-1/2, such Participant’s Required Beginning Date shall be determined under clause (i) next above.

11.5. Beneficiary Designations. Subject to the foregoing provisions of this Section 11, the term “Beneficiary” means any legal or natural person or persons (who may be designated contingently or successively) that the Participant designates to receive the vested portion of his Accounts upon his death; provided, however, that if a Participant was employed by an Employer or Related Company on or after August 22, 1984, and is legally married on the date of his death, the Beneficiary shall be the Participant’s spouse unless:

	(a)		the Participant’s spouse consents to the designation of a Beneficiary other than such spouse in a writing which is filed with the Administration Committee in such form as the Administration Committee may require and which is witnessed by either a notary public or a Plan representative appointed or approved by the Administration Committee; or

	(b)		it is established to the satisfaction of the Administration Committee that the consent required under paragraph (a) next above cannot be obtained because there is no spouse, because the spouse cannot be located or because of such other circumstances as the Secretary of the Treasury may prescribe in regulations.

A beneficiary designation form will be effective only when the signed form is received by the Administration Committee while the Participant is alive and will cancel all beneficiary designation forms signed earlier. In default of such designation, or at any time when there is no surviving spouse and no surviving Beneficiary designated by the Participant, the Administration Committee, in its discretion, may direct the Trustee to pay the Participant’s benefits to either:

	(c)		one or more of his relatives by blood, adoption or marriage and in such proportions as the Administration Committee decides; or

	(d)		the legal representative or representatives of the estate of the last to die of the Participant and his Beneficiary.

If there is any question as to the right of any Beneficiary to receive a distribution under the Plan, the Administration Committee, in its sole discretion, may make payment to the legal representative or representatives of the Participant’s estate.

11.6. Forfeitures and Restorations of Unvested Contributions. If a Termination Date occurs with respect to a Participant prior to his attaining age 65, before he is credited with five Years of Service under the Plan or is otherwise fully vested in his Account, the unvested portion of such Participant’s Matching Account and Employer Account shall be forfeited as of the Accounting Date next following or coinciding with the earlier of the date as of which he receives a distribution of the vested portion of his Accounts or the date he completes five consecutive One Year Breaks in Service. If, however, the Participant is reemployed by an Employer or Related Company before he incurs five consecutive One Year Breaks in Service, the amount forfeited (without adjustment for gains or losses after the forfeiture), if any, shall be restored to his Matching Account and Employer Account, as applicable, as of the last day of the Plan Year in which he was reemployed. Any such restoration shall be made first from current forfeitures, if any, under the Plan and then, if necessary, from a special Employer contribution. If the Participant received a distribution of the vested portion of his Matching Account or Employer Account, the amount restored under the preceding sentence shall be maintained in a separate subaccount within the Participant’s Matching Account or Employer Account. Such Participant’s vested interest in each subaccount shall be determined by adding the amount of the prior distribution from his Matching Account or Employer Account to his separate subaccount balance before applying the schedule in subsection 9.1, and then subtracting the amount of the prior distribution from the amount derived after application of such schedule. If, instead, the Participant is reemployed by an Employer or Related Company after he incurs five consecutive One Year Breaks in Service, his reemployment shall have no effect on the forfeiture under this subsection 11.6.

11.7. Application of Forfeitures. Any forfeitures of Matching Contributions (and earnings thereon) or Employer Contributions (and earnings thereon) arising during a Plan Year beginning after December 31, 2007 shall

first be used to restore any prior forfeitures required pursuant to subsection 11.6, and then shall be used to reduce future Matching Contributions.

11.8. Facility of Payment. Notwithstanding the provisions of subsections 11.1 and 11.2, if, in the Administration Committee’s opinion, a Participant or Beneficiary is under a legal disability or is in any way incapacitated so as to be unable to manage his financial affairs, the Administration Committee may direct the Trustee to make payment to a relative or friend of such person for his benefit until claim is made by a conservator or other person legally charged with the care of his person or his estate. Thereafter, any benefits under the Plan to which such Participant or Beneficiary is entitled shall be paid to such conservator or other person legally charged with the care of his person or his estate.

11.9. Direct Rollover Option. For purposes of this direct rollover provision: (i) any amount that is distributed on account of hardship shall not be an eligible rollover distribution and the distributee may not elect to have any portion of such a distribution paid directly to an eligible retirement plan; and (ii) a portion of a distribution shall not fail to be an eligible rollover distribution merely because the portion consists of after-tax employee contributions which are not includible in gross income; provided, however, that any such portion may be transferred only to (A) an individual retirement account or annuity described in Section 408(a) or (b) of the Code; or (B) a qualified defined contribution plan described in Section 401(a) or 403(a) of the Code or, in the case of a distribution after December 31, 2006, a qualified defined benefit plan described in Section 401(a) or annuity contract described in Section 403(b) that, in either case, agrees to separately account for the amount so transferred (and the earnings thereon), including separately accounting for the portion of such distribution which is includible in gross income and the portion of such distribution which is not so includible. Effective for distributions made after December 31, 2006 with respect to a deceased Participant’s Beneficiary who is not a spouse but who is a designated beneficiary within the meaning of Section 401(a)(9)(E), such Beneficiary may direct the Administration Committee to transfer such distribution, or portion thereof, to an eligible retirement plan described in Section 408(a) or (b) of the Code that is established for the purposes of receiving the distribution on behalf of such Beneficiary to the extent that such transfer is permitted by Code Section 402(c)(11) and complies with uniform rules established by the Administration Committee.

11.10. Interests Not Transferable. The interests of Participants and other persons entitled to benefits under the Plan are not subject to the claims of their creditors and may not be voluntarily or involuntarily assigned, alienated or encumbered, except in the case of loans made under the Plan and qualified domestic relations orders that relate to the provision of child support, alimony or marital rights of a spouse, child or other dependent and which meet such other requirements as may be imposed by Section 414(p) of the Code or regulations issued thereunder. Notwithstanding any other provision of the Plan to the contrary, distribution of the entire portion of the vested Account balance of a Participant awarded to his alternate payee may be made in a lump sum payment as soon as practicable after the Administration Committee determines that such order is qualified, without regard to whether the Participant would himself be entitled under the terms of the Plan to withdraw or receive a distribution of such vested amount at that time, so long as the terms of the order provide for such immediate distribution either specifically or by general reference to any manner of distribution permitted under the Plan.

11.11. Absence of Guaranty. None of the Administration Committee, the Trustee, or the Employers in any way guarantee the Trust Fund from loss or depreciation. The Employers do not guarantee any payment to any person. The liability of the Trustee to make any payment is limited to the available assets of the Trust Fund.

11.12. Missing Participants or Beneficiaries. Each Participant and each designated Beneficiary must file with the Administration Committee from time to time in writing his post office address and each change of post office address. Any communication, statement or notice addressed to a Participant or designated Beneficiary at his last post office address filed with the Administration Committee, or, in the case of a Participant, if no address is filed with the Administration Committee, then at his last post office address as shown on the Employers’ records, will be binding on the Participant and his designated Beneficiary for all purposes of the Plan. None of the Administration Committee, the Employers nor the Trustee will be required to search for or locate a Participant or designated Beneficiary.

11.13. Explanation of Optional Forms and Consent. Each Participant whose Termination Date has occurred and who is eligible to receive a distribution hereunder shall be given a notice of his right, if any to defer receipt of the distribution and a description of the consequences of failing to defer receipt, and a notice of his right, if any, described in subsection 11.9 (relating to eligible rollover distributions), and a general description of the optional forms of payment, if any, available to him under the Plan. Such notice shall be provided not less than 30

days nor more than 180 days before the date distribution commences. Notwithstanding the foregoing, a distribution may be made less than 30 days after the notice required by this subsection 11.13 is provided to the Participant if the Participant (i) has been informed of his right to consider his decision for at least 30 days, and (ii) after receiving the notice, affirmatively elects a distribution; provided, however, that in the case of a Participant who has elected to receive a distribution in the form described in paragraph 11.2(c) (relating to annuity contracts), a Participant shall be permitted to revoke his distribution election at any time prior to his Annuity Starting Date (within the meaning of Section 417(e) of the Code and regulations thereunder) or, if later, prior to the expiration of the 7-day period beginning on the day after the notice is provided to him, and no distribution with respect to such Participant shall commence before the expiration of such 7-day period. To the extent applicable, the provisions of this subsection 11.13 shall also apply to a withdrawal described in Section 10.

11.14. Required Minimum Distributions After 2001. With respect to distributions under the Plan made for calendar years beginning on or after January 1, 2002, the Plan will apply the minimum distribution requirements of Section 401(a)(9) of the Code in accordance with the regulations under Section 401(a)(9) that were proposed on January 17, 2001 (the 2001 Proposed Regulations), notwithstanding any provision of the Plan to the contrary. This amendment shall continue in effect until the last calendar year beginning before the effective date of the final regulations under Section 401 (a)(9) or such other date as may be published by the Internal Revenue Service.

11.15. Required Minimum Distributions After 2002. Required minimum distributions for Plan Years beginning on and after January 1, 2003 shall be determined in accordance with the provisions of Supplement E.

11.16. Restrictions on Distributions. Notwithstanding anything in the Plan to the contrary, amounts attributable to Before-Tax Contributions shall not be distributed earlier than upon one of the following events:

	(a)		an Employee’s severance from employment, death or disability;

	(b)		the termination of the Plan without the establishment of a successor plan;

	(c)		an Employee’s attainment of age fifty-nine and one half (59 ¹/2);

	(d)		the Participant’s “hardship” as defined under Code Section 401(k) and Section 10.3 of this Plan; or

	(e)		in the case of a qualified reservist distribution, the period described in Section 72(t)(2)(G)(iii)(III).

SECTION 12

The Administration Committee

12.1. Membership and Authority. The Administration Committee referred to in subsection 1.3 shall consist of one or more Members who shall be appointed by the Board of Directors of the Company. The Members of the Administration Committee shall be the “named fiduciaries” (as described in Section 402 of ERISA) under the Plan. Except as otherwise specifically provided in this Section 12, in controlling and managing the operation and administration of the Plan, the Administration Committee shall act by a majority of its then Members, by meeting or by writing filed without meeting, and shall have the following powers, rights and duties in addition to those vested in it elsewhere in the Plan:

	(a)		To adopt such rules of procedure and regulations as, in its opinion, may be necessary for the proper and efficient administration of the Plan and as are consistent with the provisions of the Plan.

	(b)		To enforce the Plan in accordance with its terms and with such applicable rules and regulations as may be adopted by the Administration Committee.

	(c)		To determine conclusively all questions arising under the Plan, including the power to determine the eligibility of employees or rights of Participants and other persons entitled to benefits under

			the Plan and their respective benefits, and to remedy any ambiguities, inconsistencies or omissions of whatever kind.

	(d)		To maintain and keep adequate records concerning the Plan and concerning its proceedings and acts in such form and detail as the Administration Committee may decide.

	(e)		To direct all payments of benefits under the Plan.

	(f)		To act as the “plan administrator” as defined in Section 414(g) of the Code.

The certificate of a majority of the Members of the Administration Committee that it has taken or authorized any action shall be conclusive in favor of any person relying on the certificate.

12.2. Delegation By Administration Committee. In exercising its authority to control and manage the operation and administration of the Plan, the Administration Committee may employ agents and counsel (who may also be employed by the Employers) and delegate to them such powers as the Administration Committee deems desirable. Any such delegation shall be in writing and shall reflect the unanimous action of the Members then acting. The writing described in the foregoing sentence shall fully describe the advice to be rendered or the functions and duties to be performed by the delegate or appointee.

12.3. Uniform Rules. In managing the Plan, the Administration Committee will uniformly apply rules and regulations adopted by it to all persons similarly situated.

12.4. Information to be Furnished to Administration Committee. The Employers shall furnish the Administration Committee such data and information as may be required. The records of the Employers and Related Companies as to an employee’s or Participant’s period of employment, termination of employment and the reasons therefor, leave of absence, reemployment and Compensation shall be conclusive on all persons unless determined to be incorrect. Participants and other persons entitled to benefits under the Plan must furnish to the Administration Committee such evidence, dates or information as it considers desirable to carry out the Plan.

12.5. Administration Committee’s Decision Final. To the extent permitted by law, any interpretation of the Plan and any decision on any matter within the discretion of the Administration Committee, made by it in good faith, is binding on all persons. A misstatement or other mistake of fact shall be corrected when it becomes known, and the Administration Committee shall make such adjustment on account thereof as it considers equitable and practicable.

12.6. Exercise of Administration Committee’s Duties. Notwithstanding any other provisions of the Plan, the Administration Committee shall discharge its duties hereunder solely in the interests of the Participants and other persons entitled to benefits under the Plan and:

	(a)		for the exclusive purpose of providing benefits to Participants and other persons entitled to benefits under the Plan; and

	(b)		with 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 the conduct of an enterprise of a like character and with like aims.

12.7. Remuneration and Expenses. No remuneration shall be paid to any Administration Committee Member as such. However, the reasonable expenses of a Member incurred in the performance of an Administration Committee function shall be reimbursed by the Employers in such proportions as the Company decides.

12.8. Indemnification of the Administration Committee. The Administration Committee and the individual Members thereof shall be indemnified by the Employers against any and all liabilities, losses, costs, and expenses (including legal fees and expenses) of whatsoever kind and nature which may be imposed on, incurred by or asserted against the Administration Committee or its Members by reason of the performance of an Administration Committee function if the Administration Committee or such Members did not act dishonestly or in willful violation of the law or regulation under which such liability, loss, cost or expense arises.

12.9. Designation or Removal of Administration Committee Member. An Administration Committee Member may resign at any time by giving ten days’ advance written notice to the Employers, the Trustee and the other Administration Committee Members. The Company may remove an Administration Committee Member by giving advance written notice to him, the other Employers, the Trustee and the other Administration Committee Members.

12.10. Appointment of Successor Administration Committee Member. The Company may fill any vacancy in the membership of the Administration Committee and shall give prompt written notice thereof to the other Members, the other Employers and the Trustee. While there is a vacancy in the membership of the Administration Committee, the remaining Members shall have the same powers as the full Administration Committee until the vacancy is filled.

12.11. Interested Administration Committee Member. A Member of the Administration Committee may not decide or determine any matter or question concerning his own benefits under the Plan or as to how they are to be paid to him unless such decision could be made by him under the Plan if he were not a Member of the Administration Committee.

SECTION 13

Amendment and Termination

13.1. Amendment. While the Employers expect and intend to continue the Plan, the Company must reserve and reserves the right, subject to the provisions of the Trust Agreement, to amend the Plan at any time, except that no amendment shall reduce a Participant’s Plan interest to less than the amount he would have been entitled to receive if he had resigned from the employ of all of the Employers and the Related Companies on the day of the amendment and no amendment will eliminate an optional form of benefit with respect to a Participant or Beneficiary except as otherwise permitted by law.

13.2. Termination. The Plan will terminate as to all of the Employers on any day specified by the Company if thirty days’ advance written notice of the termination is given to the Trustee and the other Employers. The Plan will terminate as to any Employer on the first to occur of the following:

	(a)		the date it is terminated by that Employer if thirty days’ advance written notice of the termination is given to the Trustee and the other Employers;

	(b)		the date that Employer completely discontinues its contributions under the Plan;

	(c)		the date that Employer is judicially declared bankrupt or insolvent; or

	(d)		the dissolution, merger, consolidation or reorganization of that Employer, or the sale by that Employer of all or substantially all of its assets, except that, subject to the provisions of subsection 13.3, with the consent of the Company, in any such event arrangements may be made whereby the Plan will be continued by any successor to that Employer or any purchaser of all or substantially all of that Employer’s assets, in which case the successor or purchaser will be substituted for the Employer under the Plan.

13.3. Merger and Consolidation of the Plan, Transfer of Plan Assets. In the case of any merger or consolidation with, or transfer of assets and liabilities to, any other plan, provisions shall be made so that each affected Participant in the Plan on the date thereof (if the Plan, as applied to that Participant, then terminated) would receive a benefit immediately after the merger, consolidation or transfer which is equal to or greater than the benefit he would have been entitled to receive immediately prior to the merger, consolidation or transfer if the Plan, as applied to him, had then terminated.

13.4. Distribution on Termination and Partial Termination. If, on termination of the Plan as applied to any Employer, a Participant remains an employee of an Employer or Related Company, the amount of his benefits shall be retained in the Trust until after his termination of employment with all of the Employers and Related Companies and shall be paid to him or, in the event of his death, to his Beneficiary, in accordance with the provisions of Section 11. The benefits payable to a Participant whose employment with all of the Employers and Related Companies is terminated coincident with the termination of the Plan as applied to his Employer (and the

benefits payable to an affected Participant on partial termination of the Plan) shall be paid to him in a lump sum. All appropriate accounting provisions of the Plan will continue to apply until the benefits of all affected Participants have been distributed to them.

13.5. Notice of Amendment, Termination or Partial Termination. Affected Participants will be notified of an amendment, termination or partial termination of the Plan as required by law.

APPENDIX C

Final 415 Regulations

Section 1. Effective Date of Appendix. This Appendix C is effective for limitation years and plan years beginning on or after July 1, 2007, except as otherwise provided herein.

Section 2. Inconsistent Provisions. This Appendix C supersedes the provisions of the Plan to the extent those provisions are inconsistent with the provisions of this Appendix.

Section 3. Section 415 Compensation Paid After Severance From Employment. Compensation used for purposes of complying with Section 415 of the Code (“Section 415 Compensation”) shall be adjusted as set forth herein for the following types of compensation paid after a Participant’s severance from employment with the Employer maintaining the Plan (or any other entity that is treated as the Employer pursuant to Code Section 414(b), (c), (m) or (o)). However, amounts described in subsections (a) and (b) below may only be included in Section 415 Compensation to the extent such amounts are paid by the later of 2¹/2 months after severance from employment or by the end of the limitation year that includes the date of such severance from employment. Any other payment of compensation paid after severance of employment that is not described in the following types of compensation is not considered Section 415 Compensation within the meaning of Code Section 415(c)(3), even if payment is made within the time period specified above.

(a)

Regular Pay. Section 415 Compensation shall include regular pay after severance of employment if:

	(1)		the payment is regular compensation for services during the Participant’s regular working hours, or compensation for services outside the Participant’s regular working hours (such as overtime or shift differential), commissions, bonuses, or other similar payments; and

	(2)		the payment would have been paid to the Participant prior to a severance from employment if the Participant had continued in employment with the Employer.

	(b)		Leave Cashouts and Deferred Compensation. Leave cashouts shall be included in Section 415 Compensation if those amounts would have been included in the definition of Section 415 Compensation if they were paid prior to the Participant’s severance from employment, and the amounts are payment for unused accrued bona fide sick, vacation, or other leave, but only if the Participant would have been able to use the leave if employment had continued. In addition, deferred compensation shall be included in Section 415 Compensation if the compensation would have been included in the definition of Section 415 Compensation if it had been paid prior to the Participant’s severance from employment, and the compensation is received pursuant to a nonqualified unfunded deferred compensation plan, but only if the payment would have been paid at the same time if the Participant had continued in employment with the Employer and only to the extent that the payment is includible in the Participant’s gross income.

	(c)		Salary Continuation Payments for Military Service Participants. Section 415 Compensation does include payments to an individual who does not currently perform services for the Employer by reason of qualified military service (as that term is used in Code Section 414(u)(1)) to the extent those payments do not exceed the amounts the individual would have received if the individual had continued to perform services for the Employer rather than entering qualified military service.

	(d)		Salary Continuation Payments for Disabled Participants. Section 415 Compensation does include compensation paid to a Participant who is permanently and totally disabled (as defined in Code Section 22(e)(3)). This provision shall apply to non-highly compensated Participants.

App. 4

Section 4. Administrative Delay. Section 415 Compensation for a limitation year shall include amounts earned but not paid during the limitation year solely because of the timing of pay periods and pay dates, provided the amounts are paid during the first few weeks of the next limitation year, the amounts are included on a uniform and consistent basis with respect to all similarly situated Participants, and no compensation is included in more than one limitation year.

Section 5. Inclusion of Certain Nonqualified Deferred Compensation Amounts. If the Plan’s definition of Compensation for purposes of Code Section 415 is the definition in Treasury Regulation Section 1.415(c)-2(b) and the simplified compensation definition of Treasury Regulation 1.415(c)-2(d)(2) is not used, then Section 415 Compensation shall include amounts that are includible in the gross income of a Participant under the rules of Code Section 409A or Code Section 457(f)(1)(A) or because the amounts are constructively received by the Participant.

Section 6. Definition of Annual Additions. The Plan’s definition of “annual additions” is modified as follows:

	(a)		Restorative Payments. Annual additions for purposes of Code Section 415 shall not include restorative payments. A restorative payment is a payment made to restore losses to a Plan resulting from actions by a fiduciary for which there is reasonable risk of liability for breach of a fiduciary duty under ERISA or under other applicable federal or state law, where Participants who are similarly situated are treated similarly with respect to the payments. Generally, payments are restorative payments only if the payments are made in order to restore some or all of the plan’s losses due to an action (or a failure to act) that creates a reasonable risk of liability for such a breach of fiduciary duty (other than a breach of fiduciary duty arising from failure to remit contributions to the Plan). This includes payments to a plan made pursuant to a Department of Labor order, the Department of Labor’s Voluntary Fiduciary Correction Program, or a court-approved settlement, to restore losses to a qualified defined contribution plan on account of the breach of fiduciary duty (other than a breach of fiduciary duty arising from failure to remit contributions to the Plan). Payments made to the Plan to make up for losses due merely to market fluctuations and other payments that are not made on account of a reasonable risk of liability for breach of a fiduciary duty under ERISA are not restorative payments and generally constitute contributions that are considered annual additions,

	(b)		Other Amounts. Annual additions for purposes of Code Section 415 shall not include: (1) the direct transfer of a benefit or employee contributions from a qualified plan to this Plan; (2) rollover contributions (as described in Code Sections 401(a)(31), 402(c)(1), 403(a)(4), 403(b)(8), 408(d)(3), and 457(e)(16)); (3) repayments of loans made to a Participant from the Plan; and (4) repayments of amounts described in Code Section 411(a)(7)(13) (in accordance with Code Section 411(a)(7)(C)) and Code Section 411(a)(3)(D) or repayment of contributions to a governmental plan (as defined in Code Section 414(d)) as described in Code Section 415(k)(3), as well as Employer restorations of benefits that are required pursuant to such repayments.

Section 7. Change of Limitation Year. The limitation year may only be changed by a Plan amendment. Furthermore, if the Plan is terminated effective as of a date other than the last day of the Plan’s limitation year, then the Plan is treated as if the Plan had been amended to change its limitation year.

Section 8. Excess Annual Additions. Notwithstanding any provision of the Plan to the contrary, if the annual additions (within the meaning of Code Section 415) are exceeded for any Participant, then the Plan may only correct such excess in accordance with the Employee Plans Compliance Resolution System (EPCRS) as set forth in Revenue Procedure 2006-27 or any superseding guidance, including, but not limited to, the preamble of the final Section 415 regulations

App. 5

Section 9. Aggregation and Disaggregation of Plans.

(a)

For purposes of applying the limitations of Code Section 415, all defined contribution plans (without regard to whether a plan has been terminated) ever maintained by the Employer (or a “predecessor employer”) under which the Participant receives annual additions are treated as one defined contribution plan. The “Employer” means the Employer that adopts this Plan and all members of a controlled group or an affiliated service group that includes the Employer (within the meaning of Code Sections 414(b), (c), (m) or (o)), except that for purposes of this Section 9, the determination shall be made by applying Code Section 415(h), and shall take into account tax-exempt organizations under Treasury Regulation Section 1.414(c)-5, as modified by Treasury Regulation Section l.415(a)-1(f)(1). For purposes of this Section 9:

	(1)		A former Employer is a “predecessor employer” with respect to a Participant in a plan maintained by an Employer if the Employer maintains a plan under which the Participant had accrued a benefit while performing services for the former Employer, but only if that benefit is provided under the plan maintained by the Employer. For this purpose, the formerly affiliated plan rules in Treasury Regulation Section 1.415(f)-1(b)(2) apply as if the Employer and predecessor employer constituted a single employer under the rules described in Treasury Regulation Section 1.415(a)-l(f)(1) and (2) immediately prior to the cessation of affiliation (and as if they constituted two, unrelated employers under the rules described in Treasury Regulation Section 1.415(a)-1(f)(1) and (2) immediately after the cessation of affiliation) and cessation of affiliation was the event that gives rise to the predecessor employer relationship, such as a transfer of benefits or plan sponsorship.

	(2)		With respect to an Employer of a Participant, a former entity that antedates the Employer is a “predecessor employer” with respect to the Participant if, under the facts and circumstances, the employer constitutes a continuation of all or a portion of the trade or business of the former entity.

	(b)		Break-up of an Affiliate Employer or an Affiliated Service Group. For purposes of aggregating plans for Code Section 415, a “formerly affiliated plan” of an employer is taken into account for purposes of applying the Code Section 415 limitations to the employer, but the formerly affiliated plan is treated as if it had terminated immediately prior to the “cessation of affiliation.” For purposes of this paragraph, a “formerly affiliated plan” of an employer is a plan that, immediately prior to the cessation of affiliation, was actually maintained by one or ▇▇▇▇ of the entities that constitute the employer (as determined under the employer affiliation rules described in Treasury Regulation Section 1.415(a)-l(f)(1) and (2)), and immediately after the cessation of affiliation, is not actually maintained by any of the entities that constitute the employer (as determined under the employer affiliation rules described in Treasury Regulation Section 1.415(a)-1(f)(l) and (2)). For purposes of this paragraph, a “cessation of affiliation” means the event that causes an entity to no longer be aggregated with one or more other entities as a single employer under the employer affiliation rules described in Treasury Regulation Section 1.415(a)-l (f)(1) and (2) (such as the sale of a subsidiary outside a controlled group), or that causes a plan to not actually be maintained by any of the entities that constitute the employer under the employer affiliation rules of Treasury Regulation Section 1.415(a)-1(f)(1) and (2) (such as a transfer of plan sponsorship outside of the controlled group).

	(c)		Midyear Aggregation. Two or more defined contribution plans that are not required to be aggregated pursuant to Code Section 415(f) and the Treasury Regulations thereunder as of the first day of a limitation year do not fail to satisfy the requirements of Code Section 415 with respect to a Participant for the limitation year merely because they are aggregated later in that limitation year, provided that no annual additions are credited to the Participant’s account after the date on which the plans are required to be aggregated.

App. 6

Section 10. Compensation For Purposes of Allocations and Contributions. The provision of the Plan setting forth the definition of compensation for purposes of allocating matching or profit-sharing contributions (hereinafter referred to as “Plan Compensation”) shall be adjusted, in the same manner as Section 415 Compensation pursuant to Sections 3 through 5 of this Exhibit, except in applying Sections 3 through 5, the term “limitation year” shall be replaced with the term “plan year” and the term “415 Compensation” shall be replaced with the term “Plan Compensation.” Notwithstanding any other provision in this Exhibit to the contrary, if the Plan is a 401(k) plan, then Participants may not make elective deferrals with respect to amounts that are not Section 415 Compensation.

A. M. CASTLE & CO.

(Required Minimum Distributions After 2002)


Purpose and Effective Date		E-1. The provisions of this Supplement E will apply for purposes of determining required minimum distributions for calendar years beginning with the 2003 calendar year, and will take precedence over any inconsistent provisions of the Plan.

Treasury Regulations Incorporated		E-2. All distributions required under this article will be determined and made in accordance with the Treasury regulations under Section 401(a)(9) of the Internal Revenue Code; provided, however, that if the provisions of the Plan, other than this Supplement E, require an earlier commencement date or a more rapid distribution, such other provisions shall control.

Time and Manner of Distribution		E-3. The Participant’s entire interest will be distributed, or begin to be distributed, to the Participant no later than the Participant’s required beginning date. If the Participant dies before distributions begin, the Participant’s entire interest will be distributed, or begin to be distributed, no later than as follows:

		(a) If the Participant’s surviving spouse is the Participant’s sole designated beneficiary, then, except as provided in subsection E10, distributions to the designated beneficiary will begin by December 31 of the calendar year immediately following the calendar year in which the Participant died, or by December 31 of the calendar year in which the Participant would have attained age 70¹/2, if later.

		(b) If the Participant’s surviving spouse is not the Participant’s sole designated beneficiary, then, except as provided in subsection E-10, distributions to the designated beneficiary will begin by December 31 of the calendar year immediately following the calendar year in which the Participant died.

		(c) If there is no designated beneficiary as of September 30 of the year following the year of the Participant’s death, the participant’s entire interest will be distributed by December 31 of the calendar year containing the fifth anniversary of the Participant’s death.

		(d) If the Participant’s surviving spouse is the Participant’s sole designated beneficiary and the surviving spouse dies after the Participant but before distributions to the surviving spouse begin, this subsection E-3 (other than paragraph (a) next above), will apply as if the surviving spouse were the Participant.

		For purposes of this subsection E-3 and subsection E-6, unless paragraph (d) next above applies, distributions are considered to begin on the Participant’s required beginning date. If paragraph (d) next above applies, distributions are considered to begin on the date distributions are required to begin to the surviving spouse under paragraph. If distributions under an annuity purchased from an insurance company irrevocably commence to the Participant before the Participant’s required beginning date (or to the Participant’s surviving spouse before the date distributions are required to begin to the surviving spouse under paragraph (a)) next above, the date distributions are considered to begin is the date distributions actually commence.

Form of Distribution		E-4. Unless the Participant’s interest is distributed in the form of an annuity purchased from an insurance company 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

E-1

RMD’s During Participant’s		E-5. During the Participant’s lifetime, the minimum amount that will be distributed for each distribution calendar year is the lesser of:
Lifetime

		(a) the quotient obtained by dividing the Participant’s account balance by the distribution period in the Uniform Lifetime Table set forth in Section 1.401(a)(9)-9 of the Treasury regulations, using the Participant’s age as of the Participant’s birthday in the distribution calendar year; or

		(b) if the Participant’s sole designated beneficiary for the distribution calendar year is the Participant’s spouse, the quotient obtained by dividing the Participant’s account balance by the number in the Joint and Last Survivor Table set forth in Section 1.401(a)(9)-9 of the Treasury regulations, using the Participant’s and spouse’s attained ages as of the Participant’s and spouse’s birthdays in the distribution calendar year.

		Required minimum distributions will be determined under this subsection E-5 beginning with the first distribution calendar year and up to and including the distribution calendar year that includes the Participant’s date of death.

Participant Dies On or After RBD		E-6. If the Participant dies on or after the date distributions begin, distributions shall be subject to the following:

		(a) If there is a designated beneficiary, the minimum amount that will be distributed for each distribution calendar year after the year of the Participant’s death is the quotient obtained by dividing the Participant’s account balance by the longer of the remaining life expectancy of the Participant or the remaining life expectancy of the Participant’s designated beneficiary, determined as follows:

		(1) The Participant’s remaining life expectancy is calculated using the age of the Participant in the year of death, reduced by one for each subsequent year

		(2) If the Participant’s surviving spouse is the Participant’s sole designated beneficiary, the remaining life expectancy of the surviving spouse is calculated for each distribution calendar year after the year of the Participant’s death using the surviving spouse’s age as of the spouse’s birthday in that year. For distribution calendar years after the year of the surviving spouse’s death, the remaining life expectancy of the surviving spouse is calculated using the age of the surviving spouse as of the spouse’s birthday in the calendar year of the spouse’s death, reduced by one for each subsequent calendar year.

		(3) If the Participant’s surviving spouse is not the Participant’s sole designated beneficiary, the designated beneficiary’s remaining life expectancy is calculated using the age of the beneficiary in the year following the year of the Participant’s death, reduced by one for each subsequent year.

		(b) If there is no designated beneficiary as of September 30 of the year after the year of the Participant’s death, the minimum amount that will be distributed for each distribution calendar year after the year of the Participant’s death is the quotient obtained by dividing the Participant’s account balance by the Participant’s remaining

E-2


		life expectancy calculated using the age of the Participant in the year of death, reduced by one for each subsequent year.

Participant Dies Before RBD		E-7. If the Participant dies before the date distributions begin, distributions shall be subject to the following:

		(a) Except as provided in subsection E-10 or E-11, there is a designated beneficiary, the minimum amount that will be distributed for each distribution calendar year after the year of the Participant’s death is the quotient obtained by dividing the Participant’s account balance by the remaining life expectancy of the Participant’s designated beneficiary, determined as provided in subsection E-6.

		(b) If there is no designated beneficiary as of September 30 of the year following the year of the Participant’s death, distribution of the Participant’s entire interest will be completed by December 31 of the calendar year containing the fifth anniversary of the Participant’s death.

		(c) If the Participant’s surviving spouse is the Participant’s sole designated beneficiary, and the surviving spouse dies before distributions are required to begin to the surviving spouse under subsection E-3(a), this subsection E-7 will apply as if the surviving spouse were the Participant.

Definitions		E-8. The following provisions shall apply for purposes of this Supplement E.

		(a) “Designated beneficiary” is the individual who is designated as the beneficiary under subsection 11.5 of the Plan and is the designated beneficiary under Section 401(a)(9) of the Internal Revenue Code and Section 1.401(a)(9)-1, Q&A-4, of the Treasury regulations.

		(b) “Distribution calendar year” is a calendar year for which a minimum distribution is required. For distributions beginning before the Participant’s death, the first distribution calendar year is the calendar year immediately preceding the calendar year which contains the Participant’s required beginning date. For distributions beginning after the Participant’s death, the first distribution calendar year is the calendar year in which distributions are required to begin under subsection E-7. The required minimum distribution for the Participant’s first distribution calendar year will be made on or before the Participant’s required beginning date. The required minimum distribution for other distribution calendar years, including the required minimum distribution for the
