-19- SECTION 4 PARTICIPANT AND MATCHING CONTRIBUTIONS 4.1 Pre-Tax Contributions Each Participant may make Pre-Tax Contributions by electing to defer an amount of Compensation before the imposition of Federal income taxes. Subject to the conditions and limitations of the Plan, each Participant may elect on an Approved Form of Election to make Pre-Tax Contributions for each Plan Year in whole percentages of 1% up to 40% of Compensation. For this purpose, Compensation shall only include Compensation paid during the period that the Participant’s election to make Pre-Tax Contributions is in effect. An Employee is not required to make Pre-Tax Contributions in order to participate in the Plan. (a) Deemed Pre-Tax Contribution Rate. Each Participant whose participation in the Plan is not subject to a collective bargaining agreement and who does not make an affirmative Pre-Tax Contribution election (including an election to not make Pre-Tax Contributions) within 30 days of first becoming eligible shall be deemed to have elected an Pre-Tax Contribution rate of 2% of Compensation for the Plan Year. Prior to the date on which such deemed Pre-Tax Contribution rate becomes effective, each Participant described in the preceding sentence shall be provided with a notice explaining his or her right to not make Pre-Tax Contributions (or to elect a different Pre-Tax Contribution rate) and, after receiving such notice, shall have a reasonable period before the deemed Pre-Tax Contribution rate becomes effective in which to elect to receive the Compensation in the form of cash in lieu of making Pre-Tax Contributions. (b) Carryover Pre-Tax Contribution Rate. Each Participant, who, immediately before becoming a Participant in this Plan, was an active participant in a Prior Plan and had an election to make Code Section 401(k) compensation deferrals on file under the Prior Plan, shall be deemed to have elected the same percentage of Pre-Tax Contributions as he or she elected under the Prior Plan until he or she makes a Pre-Tax Contribution election under this Subsection 4.1. Each Participant who was eligible to participate in a Prior Plan but did not have an election to make Code Section 401(k) compensation deferrals on file under the Prior Plan shall be deemed to have elected a Pre-Tax Contribution rate of 2% of Compensation for the Plan Year. Prior to the date on which such deemed Pre-Tax Contribution rate becomes effective, each Participant described in the preceding sentence shall be provided with a notice explaining his or her right to not make Pre-Tax Contributions (or to elect a different Pre-Tax Contribution rate) and, after receiving such notice, shall have a reasonable period before the deemed Pre-Tax Contribution rate becomes effective in which to elect to receive the Compensation in the form of cash in lieu of making Pre-Tax Contributions. Notwithstanding the foregoing, if a Participant described in this Paragraph was ineligible to make Code Section 401(k) compensation deferrals under the Prior Plan immediately before the date the Prior Plan merged into the Plan because he or she had taken a hardship withdrawal under the Prior Plan, then he or she shall become eligible to

-20- make Pre-Tax Contributions in accordance with this Paragraph (b) immediately following the end of the six-month period commencing on the effective date of the hardship withdrawal. (c) Automatic Annual Increase in Pre-Tax Contribution Rate. Subject to the conditions and limitations of the Plan, each Participant whose participation in the Plan is not subject to a collective bargaining agreement shall be deemed to have elected to increase his or her Pre-Tax Contribution rate by one percentage point effective each January 1; provided, that such automatic annual increase shall not apply to the extent such increase would cause the Participant’s Pre-Tax Contribution rate to exceed 10%. Prior to the commencement of the automatic annual increase (and each subsequent January 1), each eligible Participant shall be provided with a notice explaining his or her right to decline participation in the automatic annual increase and, after receiving such notice, shall have a reasonable period before the automatic annual increase becomes effective to decline participation. This automatic annual increase shall not apply in future years to a Participant who has previously declined participation, unless such Participant makes an affirmative election to participate in the automatic annual increase or ceases to be eligible to participate in the Plan and again becomes a Participant under Subsection 3.2. 4.2 After-Tax Contributions Each Participant may also make After-Tax Contributions by electing to contribute an amount from his or her Compensation after the imposition of Federal income taxes. Subject to the conditions and limitations of the Plan, each Participant may elect on an Approved Form of Election to make After-Tax Contributions in whole percentages of 1% to 6% of Compensation. A Participant’s After-Tax Contributions may be made by regular payroll deductions or in any other method approved by the Committee. 4.3 Catch-Up Contributions All Participants who are eligible to make Pre-Tax Contributions and who have attained (or shall attain) age 50 before the close of the Plan Year may elect on an Approved Form of Election to make Catch-Up Contributions for each Plan Year in whole percentages of 1% to 40% of Compensation, subject to the limitations of Code Section 414(v). The Plan shall not be treated as failing to satisfy the provisions of the Plan implementing the requirements of Code Section 401(k)(3), 410(b), or 416, as applicable, by reason of a Participant’s Catch-Up Contributions. 4.4 Rules Applicable to Participant Contributions An Employer may limit the maximum contribution percentage of Pre-Tax, After-Tax, and Catch-Up Contributions, provided such policy does not impermissibly discriminate against Employees who are not Highly Compensated Employees. Each Participant may elect to change, discontinue or resume Pre-Tax, After-Tax, or Catch-Up Contributions at any time by an Approved Form of Election; provided, however, that a Participant who is also a participant in the Federal Signal Corporation Savings Restoration Plan may not change, cease or otherwise modify

-21- the amount of his or her Pre-Tax Contribution election after December 31 for Compensation that otherwise would have been payable to him or her in the subsequent taxable year or years. Any Approved Form of Election shall be effective on the first day of the first payroll period for which the Employer can process such election. The Committee may establish additional rules regarding the timing and frequency of a change in the amount of Pre-Tax, After-Tax or Catch-Up Contributions, provided such policy is applied uniformly to all similarly situated Participants. 4.5 Timing of Participant Contributions Each Employer shall make a contribution to the Plan equal to the amount of Pre-Tax, After-Tax, and Catch-Up Contributions made by each Participant employed by that Employer. Such contributions shall be paid to the Trustee as soon as practicable following the reduction in Participants’ Compensation, but in no event more than 15 business days after the end of the month in which the reduction in Compensation is made. 4.6 Rollover Contributions At the direction of the Committee, at such time as the Committee determines, and in accordance with such rules as the Committee may establish from time to time, the Plan shall accept Rollover Contributions on behalf of an Employee who is eligible to make Pre-Tax Contributions. A Rollover Contribution may be made from: (a) A tax-qualified plan described in Code Sections 401(a) or 403(a), including after- tax employee contributions (“After-Tax Rollover Contribution”), but excluding designated Roth contributions made under a qualified Roth contribution program; (b) An annuity contract described in Code Section 403(b), excluding after-tax employee contributions and designated Roth contributions made under a qualified Roth contribution program; (c) An eligible plan under Code Section 457(b) that is maintained by a state, political subdivision of a state, or any agency or instrumentality of a state or political subdivision of a state; and (d) An individual retirement account or annuity described in Code Sections 408(a) or (b) that is eligible to be rolled over to a plan qualified under Code Section 401(a) and that would otherwise be includible in gross income. An eligible Employee may make a Rollover Contribution provided that such distribution is received by the Trustee within 60 days after the Employee’s receipt of such payment, or such amount is directly transferred to the Trust Fund from such other above plan, provided that After- Tax Rollover Contributions must be directly transferred to the Plan. The Plan shall separately account for Rollover Contributions and After-Tax Rollover Contributions. The Employee must furnish the Employer or its designee an Approved Form of Election, including a written statement that the contribution is a Rollover Contribution and such other statements and information as may be required by the Committee or its designee in order to establish that such Rollover Contribution otherwise meets the requirements of law. If the Committee learns that all or part of a Rollover Contribution did not meet the requirements of the Code and the Treasury

-22- Regulations and rulings thereunder, the Committee shall direct the Trustee to distribute to the Participant the ineligible portion of the Rollover Contribution (and earnings thereon) that was credited to the Participant’s Account. 4.7 Uniformed Service Absence Notwithstanding any provision of this Plan to the contrary, contributions, benefits and service credit with respect to qualified military service shall be provided in accordance with Code Section 414(u) and, effective as of January 1, 2007, the Heroes Earnings Assistance Relief Tax Act of 2008.

-26- SECTION 6 INVESTMENT AND FEDERAL SIGNAL STOCK PROVISIONS 6.1 Investment Funds The ESOP portion of the Plan is designed to be primarily invested in the Federal Signal Stock Fund, except that the Trustee may hold some of the assets of the Federal Signal Stock Fund in cash pending investment, distribution, reallocation or transfer. The Non-ESOP portion of the Plan shall be invested in one or more Investment Funds designated by the Investment Committee in its discretion for the investment of Participants’ Accounts. The Investment Committee, in its discretion, may from time to time establish new Investment Funds or eliminate existing Investment Funds. Contributions to the Plan may be uninvested pending allocation to the Investment Funds. The investment manager of each Investment Fund, or the Trustee if there is no investment manager, may invest the Investment Fund in short term investments or hold the assets thereof in cash pending investment, distribution, reallocation or transfer. 6.2 Investment Fund Elections and Transfers Each Participant may elect to invest his or her Accounts in whole multiples of 1% up to 100% in any one or more of the Investment Funds. The Participant’s investment election shall apply to all contributions to his or her Accounts. If a Participant fails to make an investment election, his or her Accounts shall be invested in the default investment arrangement specified by the Investment Committee in accordance with ERISA Section 404(c)(5) and related regulations until the Participant elects to change the investment of such Accounts in accordance with this Subsection. In accordance with rules established from time to time by the Committee, a Participant may elect to change his or her investment election (in whole multiples of 1% up to 100%) with respect to future contributions or transfer (in whole multiples of 1% up to 100% or in any dollar amount) all or a part of his or her Accounts from one or more Investment Fund to one or more different Investment Funds. Furthermore, pursuant to rules established by the Plan or an Investment Fund, the Investment Fund may restrict a Participant from transferring into or out of the Investment Fund if the Plan or Investment Fund determines that the Participant’s transfer activity would be detrimental to the Investment Fund. Effective as of January 1, 2007, for any period during which the Plan is an applicable defined contribution plan (as defined in Code Section 401(a)(35)) by virtue of holding publicly traded employer securities, the Committee shall permit Participants and applicable beneficiaries to direct the investment of their Accounts in accordance with Code Section 401(a)(35) and applicable Treasury Regulations or other guidance issued thereunder. 6.3 Election Procedures Any election to invest Accounts, change investment for new contributions, or make interfund transfers within the Plan (other than an automatic investment election) must be made through an Approved Form of Election. Any such election made before the Close of Business on a Business Day shall be effective and valued as of the day such election is made. Any such

-27- election made on a day other than a Business Day, or after the Close of Business on a Business Day, shall be effective and valued as of the next Business Day. Notwithstanding the foregoing, any election with respect to the Federal Signal Stock Fund shall be subject to the availability of short-term investments in such Fund. 6.4 Administration of Federal Signal Stock Fund Except as otherwise provided in Subsection 6.5, distribution of the Participant’s ESOP subaccounts, regardless of the Accounts in which they are held, shall be made in-kind or in cash as directed by the Participant. Any in-kind distribution shall be based on: (i) the total number of shares of Federal Signal Common Stock in the Federal Signal Stock Fund that are attributable to such Participant’s Accounts, valued in accordance with Subsection 6.10 as of the date of distribution, and (ii) cash in the amount equal to the value of a distributable fraction of a share of Federal Signal Common Stock in the Federal Signal Stock Fund attributable to his or her Accounts. The Participant shall at all times have the right to demand that the distribution of his or her ESOP subaccounts be made in the form of shares of Federal Signal Common Stock. Notwithstanding the previous sentence, if the Company’s charter or by-laws restrict the ownership of substantially all outstanding shares of Federal Signal Common Stock to employees or a trust defined in Code Section 401(a), the Committee shall make the entire distribution in cash or in the form of shares of Federal Signal Common Stock, subject to the requirement that such shares be immediately put to the Company under a fair valuation formula. If Federal Signal Common Stock is distributed in the form of cash, the Participant shall receive cash equal to the amount of the “fair market value” of the Federal Signal Common Stock, valued in accordance with Subsection 6.10 as of the date of distribution. For purposes of the shares of Federal Signal Common Stock, which are readily tradable on an established securities market, the term “fair market value” shall be determined based on the prevailing market price. A Participant may elect to diversify any portion of his or her Accounts that is invested in the Federal Signal Stock Fund into one or more different Investment Funds offered under the Plan. To the extent practicable, the Trustee shall follow all instructions with respect to the sale or purchase of Federal Signal Common Stock held in the Federal Signal Stock Fund. However, any election with respect to the Federal Signal Stock Fund shall be subject to the availability of short-term investments, including but not limited to cash, in such fund. 6.5 Dividend Election Any cash dividends paid with respect to shares of Federal Signal Common Stock attributable to any of the Participant’s Accounts invested in the Federal Signal Stock Fund may, as elected by the Participant, be paid in cash to (i) the Plan and reinvested in Federal Signal Common Stock (through the Federal Signal Stock Fund), (ii) the Participant on the dividend payable date, or (iii) the Trustee and distributed by the Trustee to the Participant no later than 90 days after the end of the Plan Year in which paid to the Trustee. If a Participant fails to make an affirmative election under this Subsection, the Participant shall be deemed to have elected to have the dividend paid to the Plan and reinvested in the Federal Signal Stock Fund. The Committee shall establish rules and procedures for the election, including the procedures for determining the number of shares of Federal Signal Common Stock in each Participant’s ESOP subaccounts on the record date of the dividend. Notwithstanding any other provision of the Plan

-28- to the contrary, the dividends to which this election applies shall be fully vested. Reinvested dividends shall be paid to the Plan and credited to the Participant’s ESOP subaccounts in proportion to the interest in the Federal Signal Stock Fund attributable to each Participant’s Account. 6.6 Voting of Shares in Federal Signal Stock Fund The Trustee shall notify each Participant of each meeting of the Company’s shareholders and shall furnish to each Participant copies of the proxy statements and other communications distributed to shareholders in connection with any such meeting. Each Participant shall be entitled to direct the Trustee as to the manner in which any voting rights of shares of Federal Signal Common Stock attributable to his or her proportionate interest (vested or unvested) in the Federal Signal Stock Fund are to be exercised. The Trustee shall exercise the voting rights of such shares in accordance with the most recent and timely direction received by the Trustee from such Participant. If the Trustee does not receive direction with respect to the voting of shares held in the Federal Signal Stock Fund within the time specified in the notification, the Trustee shall vote such shares in the same manner and in the same proportion as the shares for which the Trustee received voting instructions. 6.7 Tendering of Shares in Federal Signal Stock Fund The Trustee shall notify each Participant of any tender offer for, exchange of, or a request or invitation for tenders of Federal Signal Common Stock and shall request from each Participant instructions for the Trustee as to the tendering of Federal Signal Common Stock credited to the Participant’s Accounts. A “tender offer” shall mean any tender or exchange offer for, or request or invitation for tenders or exchanges of, shares of Federal Signal Common Stock and shall include any tender offer made by or on behalf of the Company. Each Participant shall direct the Trustee on the tendering, depositing, selling, exchanging or transferring of shares of Federal Signal Common Stock attributable to the Participant’s proportionate interest in the Federal Signal Stock Fund pursuant to any tender offer. The Trustee shall tender, deposit, sell, exchange or transfer such shares (or shall retain such shares in the Federal Signal Stock Fund) pursuant to a tender offer only in accordance with the most recent and timely direction received by such Participant. However, if the Trustee does not receive tender directions with respect to shares held in the Federal Signal Stock Fund within the time specified in the notification, the Participants to which such shares are attributable shall be deemed to have directed the Trustee that such shares be retained in the Federal Signal Stock Fund subject to all provisions of the Plan, the Trust Agreement, and applicable law. The proceeds of any sale, exchange or transfer of shares of Federal Signal Common Stock pursuant to the direction of a Participant in accordance with this Subsection shall be allocated to Accounts in the same manner, in the same proportion, and as of the same date as the shares were sold, exchanged or transferred. Pending receipt of directions as to which of the remaining Investment Funds the proceeds should be invested in, the proceeds shall be invested in the default investment arrangement specified by the Investment Committee in accordance with ERISA Section 404(c)(5) and related regulations.

-29- 6.8 Confidentiality of Voting and Tender Directions Except to the extent necessary to provide the Employers with information necessary to accurately maintain Plan and Participant records, the Trustee shall use its best efforts (i) to keep confidential the direction (or the absence thereof) from each Participant in connection with the exercise of voting rights of shares held in the Federal Signal Stock Fund, or with respect to any tender offer, and the identity of such Participant, and (ii) not to divulge such direction or identity to any person or entity, including, without limitation, the Company, any other Employer and any Non-Participating Employer and any director, officer, employee or agent thereof. It is the intent of this Subsection that the Company, each other Employer, and each Non-Participating Employer and their directors, officers, employees and agents not be able to ascertain the direction given (or not given) by any Participant in connection with the exercise of voting rights of such shares or with respect to any tender offer. To the extent that a Participant, Beneficiary or Alternate Payee acts with respect to the exercise of voting rights of shares held in the Federal Signal Stock Fund or the tender, deposit, sale, exchange or transfer of such shares only, such Participant, Beneficiary or Alternate Payee shall be a Fiduciary. 6.9 Invalidity of Voting or Tender Procedures To the extent the Trustee exercises any fiduciary responsibility with respect to the voting, tendering, or withdrawal of tender of shares held in the Federal Signal Stock Fund, the Trustee shall, unless pursuant to the requirements of ERISA or otherwise it is unlawful to do so, (i) take into account directions timely received from Participants as valid direction with respect to the exercise of voting rights or a tender offer, and (ii) to the extent that the Trustee deems it appropriate, take into consideration any relevant non-financial factors (in addition to any financial factors) bear in the exercise voting rights or in the sale, exchange, transfer, or tender or in the exercise of withdrawal rights. 6.10 Unitized Federal Signal Stock Fund Participants invested in the Federal Signal Stock Fund hold units of such fund. A unit of the Federal Signal Stock Fund holds shares of Federal Signal Common Stock and cash. Each day, Additions to and Reductions from (each as defined below) the Federal Signal Stock Fund are totaled. If the cash in the Federal Signal Stock Fund is above or below the amount required to settle these trades, shares of Federal Signal Common Stock are traded on the open market. At the Close of Business on each Business Day, all transactions for such day are combined and the total value of the Federal Signal Stock Fund is divided by the number of units in such fund to determine the fund’s Net Asset Value (“NAV”). NAV is the price used to determine the value of Participants’ ESOP subaccounts. The number of shares of Federal Signal Common Stock in the Federal Signal Stock Fund attributable at any particular time to the interest of a Participant shall be the approximate product of the total number of shares then held in the Federal Signal Stock Fund multiplied by a fraction, the numerator of which is the value of the Federal Signal Stock Fund then in the Participant’s ESOP subaccount and the denominator of which is the total value of the Federal Signal Stock Fund. The value of a unit in the Federal Signal Stock Fund (“Closing Unit Value”) shall be determined on each Business Day by dividing the fair market value of such fund by the number

-30- of units in such fund before taking into account Additions to and Reductions from such fund. After the Closing Unit Value is determined at the Close of Business on each Business Day, the total number of units in the Federal Signal Stock Fund shall be re-determined to take into account new units resulting from Additions to such fund and canceled units resulting from Reductions from such fund. As of the Close of Business on such Business Day, the total number of new units resulting from Additions to the Federal Signal Stock Fund shall equal the total amount of the Additions to such fund divided by the Closing Unit Value. As of the Close of Business on such Business Day, the total number of units to be canceled under the Federal Signal Stock Fund shall equal the total amount of Reductions from such fund divided by the Closing Unit Value. Whenever all or any part of the balances in the Federal Signal Stock Fund is reduced as a result of a Reduction, the reduced amount shall equal the Closing Unit Value multiplied by the number of whole and fractional units credited to such Accounts. For purposes of this Subsection, “Addition” means any amounts added to the Federal Signal Stock Fund during the day as a result of contributions to, reinstatement of Accounts and interfund transfers since the Close of Business on the immediately preceding Business Day. For purposes of this Subsection, “Reduction” means any amounts reduced from the Federal Signal Stock Fund as a result of any in-service withdrawals, loans, distributions, interfund transfers, return of any excess amounts, and forfeitures since the Close of Business on the immediately preceding Business Day. 6.11 Valuation of Investment Funds As of each Business Day, the Trustee shall report to the Investment Committee the fair market value of the assets of each Investment Fund and the number and value of units in the Federal Signal Stock Fund. The fair market value of an Investment Fund shall be the value of such Investment Fund as of the Close of Business on such Business Day. The number and value of units in the Federal Signal Stock Fund shall be determined in accordance with Subsection 6.10. 6.12 Voting of Shares in Mutual Funds Shares of mutual funds held in a Participant’s Accounts shall be voted on his or her behalf by the Trustee. In making voting decisions on the mutual fund shares, the Trustee shall vote the shares in the long-term, economic best interests of Plan Participants.

In addition to the Accounts described above, the Committee may maintain such other Accounts in the names of Participants or otherwise as the Committee considers necessary or desirable. 7.2 ESOP Subaccounts The Committee shall maintain or cause to be maintained separate subaccounts in the Accounts of each Participant to reflect the value of the Participant’s balances in the ESOP portion of the Plan and the Non-ESOP portion of the Plan. The ESOP subaccount shall reflect the portion of each Account invested in the Federal Signal Stock Fund.

Such Accounts shall continue to be so adjusted until all amounts in such Accounts are paid. 7.4 Statement of Account At such times and in such manner as determined by the Committee, each Participant shall be furnished with a statement reflecting the condition of his or her Accounts in the Trust Fund. 7.5 Accounts for Alternate Payees A separate Account shall be established for an Alternate Payee entitled to any portion of a Participant’s Account under a Qualified Domestic Relations Order in accordance with procedures established by the Committee and applicable law. Such separate Account shall be valued and accounted for in the same manner as any other Account.

If a separate Account has been established on behalf of an Alternate Payee but all of the amounts in the Account have not yet been distributed, the Alternate Payee may direct the investment of such Account in the same manner as if such Alternate Payee were a Participant. Subject to the Committee’s rules, an Alternate Payee may designate one or more Beneficiaries to receive payment of the Alternate Payee’s separate Account under the Plan in the same manner as if such Alternate Payee were a Participant, except that the Alternate Payee may designate an alternate Beneficiary other than his or her Spouse without such Spouse’s consent. 7.6 Order and Timing of Withdrawals, Loans, and Distributions Any amounts to be paid to a Participant, a Beneficiary, or an Alternate Payee shall be withdrawn from his or her Accounts on a pro rata basis or in such other order established by the Committee for withdrawals, loans, and distributions from the Plan.

-34- SECTION 8 CONTRIBUTION AND BENEFIT LIMITATIONS 8.1 Contribution Limitations For each Limitation Year, the Annual Addition to a Participant’s Account shall not exceed the lesser of $53,000 (as adjusted for cost-of-living increases under Code Section 415(d)) or 100% of the Participant’s Code Section 415 Compensation for the Limitation Year, subject to the following: (a) The compensation limit described above shall not apply to any contribution for medical benefits (within the meaning of Code Section 401(h) or Code Section 419A(f)(2)) after severance from employment that is otherwise treated as an Annual Addition. (b) The Committee shall take any actions it deems advisable to avoid an Annual Addition in excess of Code Section 415; provided, however, if a Participant’s Annual Addition for a Limitation Year actually exceeds the limitations of this Subsection, the Committee shall correct such excess in accordance with applicable guidance issued by the Internal Revenue Service. Any such correction of excess Annual Additions shall be charged against the Investment Funds in the applicable Account on a pro rata basis; provided, however, that the reduction of an excess Annual Addition of a director, officer or other principal stockholder of the Company subject to the requirements of Section 16(b) of the Securities Exchange Act of 1934 shall not decrease his or her interest in the Federal Signal Stock Fund. (c) Annual Additions shall be subject to Code Section 415 and applicable Treasury Regulations issued thereunder, the requirements of which are incorporated herein by reference to the extent not specifically provided above or in Subsection 8.2. 8.2 Combining of Plans In applying the limitations set forth in Subsection 8.1, reference to the Plan shall mean this Plan and all other defined contribution plans (whether or not terminated) maintained by the Related Employers. In complying with the requirements of Subsection 8.1, a Participant’s Annual Additions shall be limited by first reducing annual additions under the plan under which the Participant is then currently covered (or was most recently covered) as an active employee, then under the next most recent plan that covered the Participant as an active employee, and so on in reverse chronological order through all aggregated plans, until the Participant’s Annual Additions have been reduced sufficiently to comply with Code Section 415 and Subsection 8.1. 8.3 Dollar Limitations on Pre-Tax Contributions No Participant shall make Pre-Tax Contributions under this Plan, or elective deferrals under any other qualified plan maintained by an Employer, during any calendar year in excess of $18,000 (or such other amount as the Secretary of the Treasury shall specify from time to time

-35- pursuant to Code Section 402(g)), excluding Catch-Up Contributions. As of each December 31, the Committee or its designee shall determine the total Pre-Tax Contributions made by each Participant during the calendar year. In the event that the Pre-Tax Contributions for a Participant exceeds the above limitation, such Excess Deferrals (and any income allocable thereto determined in accordance with Subsection 8.6) shall be paid to the Participant by the following April 15. If a Participant’s total Pre-Tax Contributions under this Plan and any other plan of another employer for any calendar year exceed the maximum annual amount described above, the Participant may notify the Committee in writing (on or before March 1 of the next following calendar year) of the Participant’s election to have all or a portion of the Participant’s Pre-Tax Contributions (and the income allocable thereto determined in accordance with Subsection 8.6) under this Plan distributed in accordance with this Subsection. In addition, any Matching Contributions attributable to amounts distributed under this Subsection (and any income allocable thereto determined in accordance with Subsection 8.6) shall be forfeited and shall be used to reduce future Matching Contributions of the Participant’s Employer under the Plan or to pay expenses of the Plan. 8.4 Percentage Limitations on Pre-Tax Contributions In no event shall the Average Deferral Percentage (defined below) of the Participants who are Highly Compensated Employees for any Plan Year exceed the greater of: (a) The Average Deferral Percentage of all other Participants for such Plan Year multiplied by 1.25; or (b) The Average Deferral Percentage of all other Participants for such Plan Year multiplied by 2.0, provided that the Average Deferral Percentage of the Participants who are Highly Compensated Employees does not exceed that of all other eligible Participants by more than two percentage points. In accordance with applicable Treasury Regulations, an eligible Employee’s “Average Deferral Percentage” for a Plan Year means the ratio of A to B, where A equals the sum of the Pre-Tax Contributions actually paid to the Trust on behalf of each such eligible Employee for a Plan Year, and B equals the eligible Employee’s Testing Compensation for such Plan Year. From time to time during the Plan Year, the Committee may determine whether the limitation of this Subsection shall be satisfied and may limit the Pre-Tax Contributions to be withheld on behalf of Highly Compensated Employees or may refund Pre-Tax Contributions previously withheld. If, after the end of the Plan Year, the limitations of this Subsection are not satisfied, the Committee shall either refund Pre-Tax Contributions previously withheld on behalf of Highly Compensated Employees or an Employer may make qualified nonelective employer contributions. If Pre-Tax Contributions made on behalf of Highly Compensated Employees are refunded to satisfy the limitations of this Subsection, the Committee shall determine the amount of Excess Pre-Tax Contributions and shall refund such amounts on the basis of the Highly Compensated Employees’ contribution amounts. “Excess Pre-Tax Contributions” mean the amount by which Pre-Tax Contributions for a Plan Year made on behalf of Highly Compensated Employees exceeds the above limitations. Excess Pre-Tax Contributions previously withheld (and any income allocable thereto determined in accordance with Subsection 8.6) shall be distributed

-36- within 2½ months after the close of the Plan Year to which they relate. In addition, any Matching Contributions attributable to such Excess Pre-Tax Contributions (and any income allocable thereto determined in accordance with Subsection 8.6) shall be forfeited and shall be used to reduce future Matching Contributions of the Participant’s Employer or to pay Plan expenses. In order to meet the above requirements and the requirements described in the following Subsection, any Employer may establish a special rate of qualified nonelective employer contributions applicable only to certain Participants who are not Highly Compensated Employees of such Employer. The timing and amount of such qualified nonelective employer contributions shall satisfy the requirements of Treasury Regulations. 8.5 Percentage Limitations on Matching and After-Tax Contributions Except for Participants subject to a collective bargaining agreement, in no event shall the Average Contribution Percentage (defined below) of the Participants who are Highly Compensated Employees for any Plan Year exceed the greater of: (a) The Average Contribution Percentage of all other Participants for such Plan Year multiplied by 1.25; or (b) The Average Contribution Percentage of all other Participants for such Plan Year multiplied by 2.0, provided that the Average Contribution Percentage of the Participants who are Highly Compensated Employees does not exceed that of all other Participants by more than two percentage points. In accordance with applicable Treasury Regulations, an eligible Employee’s “Average Contribution Percentage” for a Plan Year means the ratio of A to B, where A equals the After- Tax and Matching Contributions made by or on behalf of each such eligible Employee for a Plan Year, and B equals the eligible Employee’s Testing Compensation received by the Employee for such Plan Year. From time to time during the Plan Year, the Committee may determine whether the limitation of this Subsection shall be satisfied and, to the extent necessary to ensure compliance with such limitation, may limit the After-Tax Contributions to be withheld on behalf of Highly Compensated Employees not subject to a collective bargaining agreement or may refund After-Tax Contributions previously withheld. If, after the end of the Plan Year, the limitations of this Subsection are not satisfied, the Committee may refund After-Tax Contributions previously withheld on behalf of Highly Compensated Employees not subject to a collective bargaining agreement. If the limitation of this Subsection still is not satisfied after application of the preceding sentence, the Committee may refund Matching Contributions previously credited to Highly Compensated Employees not subject to a collective bargaining agreement. If After-Tax Contributions or Matching Contributions made on behalf of such Highly Compensated Employees are refunded to satisfy the limitation of this Subsection, the Committee shall determine the amount of “Excess After-Tax Contributions” or “Excess Matching Contributions” and shall refund such amounts on the basis of such Highly Compensated Employees’ contribution amounts. “Excess After-Tax Contributions” and “Excess Matching

-37- Contributions” mean the amount by which After-Tax Contributions or Matching Contributions for a Plan Year made by or on behalf of Highly Compensated Employees exceed the above limitations. Excess After-Tax and Matching Contributions previously withheld (and any income allocable thereto determined in accordance with Subsection 8.6) shall be distributed within 2½ months after the close of the Plan Year to which they relate. In lieu of distributing Excess After-Tax or Matching Contributions, an Employer may make qualified nonelection employer contributions described in the preceding Subsection. 8.6 Calculating Income Allocable to Excess Deferrals and Contributions The income allocable to a distribution to a Participant for a Plan Year (as required under Subsections 8.1, 8.3, 8.4, and 8.5) shall be determined under any method permitted under Treasury Regulations and selected by the Committee, provided such method does not discriminate in favor of Highly Compensated Employees, is used consistently for all Participants and for all corrective distributions for the Plan Year, and is based on the method for allocating income to Participants’ Accounts. No income or loss shall be allocated to Excess Deferrals, Excess Pre-Tax Contributions, Excess After-Tax Contributions, or Excess Matching Contributions for the period between the end of the Plan Year in which such Excess Deferrals, Excess Pre-Tax Contributions, Excess After-Tax Contributions and/or Excess Matching Contributions arose and the date of distribution of such amounts. 8.7 Corrective Contributions/Reallocations In addition to the powers described in Subparagraph 13.5(j), the Committee may take the following actions to correct errors in the administration of the Plan: (a) If, with respect to any Plan Year, an administrative error results in a Participant’s Account not being properly credited with Pre-Tax Contributions, After-Tax Contributions, Rollover Contributions, Matching Contributions or Retirement Contributions, or earnings on any such amounts, the Committee may take corrective action, including, but not limited to, one or more of the following corrective actions, in order to place such Participant’s Account in the position that the Account would have been in had no error occurred: (i) Direct additional contributions to be made to such Participant’s Accounts; (ii) Reallocate existing contributions among the Accounts of affected Participants; or (iii) Such other actions as it considers desirable under the circumstances as are consistent with the principles of the Employee Plans Compliance Resolution System set forth in Revenue Procedure 2008-50 and/or subsequent guidance published in the Internal Revenue Bulletin. (b) If, with respect to any Plan Year, an administrative error results in an amount being credited to the Account of a Participant or any other individual who is not

-38- otherwise entitled to such amount, the Committee may take corrective action, including but not limited to: (i) Direct the forfeiture of amounts erroneously credited (with such forfeitures to be used to reduce future Employer contributions or other contributions to the Plan); (ii) Reallocate such erroneously credited amounts to other Participants’ Accounts; or (iii) Such other actions as it considers desirable under the circumstances as are consistent with the principles of the Employee Plans Compliance Resolution System set forth in Revenue Procedure 2008-50 and/or subsequent guidance published in the Internal Revenue Bulletin.

If the Plan’s vesting schedule is amended, each Participant with at least three years of Vesting Service may elect to have his or her nonforfeitable percentage determined without regard to such amendment. The period during which the election may be made shall commence with the date the amendment is adopted and shall end on the later of 60 days after the amendment is adopted, 60 days after the amendment is effective, and 60 days after the Participant receives written notice of the amendment. 9.7 Forfeitures Any portion of a Participant’s Accounts that do not vest shall be regarded as forfeitures upon such Participant’s Severance From Service. All forfeited amounts shall be used to reduce contributions of the Participant’s Employer or to pay Plan expenses. Pending allocation to reduce Employer contributions, such amounts shall be invested as directed by the Investment Committee or its designee. 9.8 Reinstatement of Accounts for Rehires If an inactive Participant who has made Pre-Tax Contributions resumes employment and again becomes a Participant at any time, or if an inactive Participant who was partially vested in any Matching Contributions or Retirement Contributions resumes employment and again becomes a Participant before incurring a Break in Service of five years, the portion of the Participant’s Accounts that was previously forfeited shall be reinstated if (i) such Participant has not received a distribution from the Plan, or (ii) such Participant received a distribution of less than the full amount of his or her Accounts repays in cash the amount of his or her previously distributed Accounts. Any such repaid amount shall be nonforfeitable.

-44- SECTION 10 PAYMENTS 10.1 Form of Payment Subject to Subsections 10.2 and 10.5, after each Participant’s Severance From Service, the vested value of the Participant’s Accounts shall be paid to or for the benefit of the Participant or his or her Beneficiary in one or more of the following forms of payment as the Participant or his or her Beneficiary elects: (a) By a single payment in cash; (b) By monthly, quarterly, semi-annual or annual installments in cash during a period not to exceed the life expectancy of the Participant or the joint life expectancy of the Participant and his or her designated Beneficiary determined at the date payments begin; provided, however, that unless the Participant elects otherwise, all distributions of the Participant’s ESOP Subaccounts shall be made over a period not longer than five years, in compliance with Code Section 409(o); or (c) By one or more payments in accordance with Paragraph (a) or (b) above, except that such payment(s) shall be made in whole shares of Federal Signal Common Stock, to the extent that the portion of such Participant’s Account balances allocated to the Federal Signal Stock Fund is evenly divisible by the fair market value of such stock on the Business Day as of which such value is determined, and the remainder of such Participant’s Account in cash. 10.2 Time of Payment Following a Participant’s Severance From Service, distribution of the balance of a Participant’s Account shall be made or commence as follows: (a) Consent Required. Payment of a Participant’s Accounts (as determined pursuant to Subsection 10.1) shall be made pursuant to the Participant’s request for payment and within the time frame established by the Committee. If the vested value of a Participant’s Accounts exceeds $5,000, such vested value shall not be paid without his or her consent. Unless a Participant elects otherwise, payment of the Participant’s Accounts shall be paid in a single cash payment not later than the 60th day after the close of the Plan Year in which the latest of: (i) the Participant’s attainment of Normal Retirement Age; (ii) the tenth anniversary of the Participant’s participation in the Plan, and (iii) the Participant’s Severance From Service date. (b) Mandatory Distributions. Notwithstanding any other provision of this SECTION 10 to the contrary, the following rules shall apply to a Participant, Beneficiary or Alternate Payee if the vested value of his or her Accounts does not exceed $5,000 (excluding the balance in his or her Rollover Account and After-

-45- Tax Rollover Account) and he or she does not make a distribution election within the time frame established by the Committee: (i) Account Balance of $1,000 or Less. If the Participant incurs a Severance From Service and if the vested value of his or her Accounts (including the value of his or her Rollover Account and After-Tax Rollover Account) does not exceed $1,000, he or she shall receive payment of such vested value in a single cash payment in accordance with rules and procedures established by the Committee; provided, that if the vested value of a Participant’s Accounts is zero, then such vested value shall be deemed paid to the Participant immediately. (ii) Account Balance Over $1,000. If the Participant incurs a Severance From Service and if the vested value of his or her Accounts (excluding the value of his or her Rollover Account and After-Tax Rollover Account) is greater than $1,000 but less than or equal to $5,000, such vested value shall be paid in a direct rollover to an individual retirement plan designated by the Committee in accordance with rules and procedures established by the Committee, unless the Participant otherwise elects to have the value of his or her Accounts paid in a single payment in cash or rolled over to an eligible retirement plan in accordance with Subsection 10.3. 10.3 Direct Rollover of Eligible Rollover Distribution If payment of a Participant’s benefits constitutes an Eligible Rollover Distribution, then the Participant or other Eligible Distributee may elect to have such distribution paid directly to an Eligible Retirement Plan. (a) Eligible Distributee means (i) an Employee or former Employee, (ii) an Employee’s or former Employee’s surviving Spouse, (iii) the Employee’s or former Employee’s Spouse or former Spouse who is the Alternate Payee under a Qualified Domestic Relations Order, and (iv) an individual who is a non-Spouse designated Beneficiary (as defined by Section 401(a)(9)(E) of the Code) of the Employee or former Employee. (b) Eligible Retirement Plan means (i) an individual retirement account described in Code Section 408(a), (ii) an individual retirement annuity described in Code Section 408(b) (other than an endowment contract), (iii) an annuity plan described in Code Section 403(a), (iv) a qualified trust described in Code Section 401(a), (v) an annuity contract described in Code Section 403(b), (vi) an eligible plan under Code Section 457(b) which is maintained by a state, political subdivision of a state, or any agency or instrumentality of a state or political subdivision of a state, or (vii) a Roth IRA as described in Code Section 408A. The definition of an Eligible Retirement Plan shall also apply in the case of a distribution to a surviving Spouse, or to a Spouse or former Spouse who is the alternate payee under a Qualified Domestic Relations Order. In the case of a non-Spouse

-46- designated Beneficiary, an Eligible Retirement Plan includes only an individual retirement account or annuity described in Code Section 408(a) or (b) or 408A, solely to the extent permitted under Code Section 402(c)(11) and the Treasury Regulations and other guidance issued thereunder. (c) Eligible Rollover Distribution means any distribution of all or any portion of the balance to the credit of the Eligible Distributee, except that an Eligible Rollover Distribution does not include: (i) any distribution that is one of a series of substantially equal periodic payments (not less frequently than annually) made for the life (or life expectancy) of the Eligible Distributee or the joint lives (or joint life expectancies) of the Eligible Distributee and the Eligible Distributee’s designated Beneficiary, or for a specified period of ten years or more, (ii) any distribution to the extent such distribution is required under Code Section 401(a)(9), (iii) any distribution made on account of financial hardship, and (iv) any distribution of less than $200. A portion of a distribution shall not fail to be an Eligible Rollover Distribution merely because the portion consists of After-Tax Contributions which are not includible in gross income. However, such portion may be transferred to an individual retirement account described in Code Section 408(a), an individual retirement annuity described in Code Section 408(b) (other than an endowment contract), an annuity plan or contract described in Code Section 403(a) or 403(b), a qualified plan described in Code Section 401(a), or a Roth IRA (solely to the extent allowed under the Code), only if such individual retirement account, individual retirement annuity, annuity plan or contract, qualified trust, or Roth IRA agrees to separately account for amounts so transferred, 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. A rollover distribution to a Roth IRA must satisfy the requirements of Code Sections 402(c) and 408A. 10.4 Designation of Beneficiary At any time before payment of a Participant’s Accounts or, if installment payments have begun, then at any time before payment of the last installment, a Participant may designate a Beneficiary or Beneficiaries (who may be executors or trustees and who shall be the same person or persons for each of the Participant’s Accounts) on an Approved Form of Election. The Participant may change or revoke any such designation on an Approved Form of Election at any time before payment of his or her Accounts or, if installment payments have begun, then at any time before payment of the last installment. A Participant’s Spouse shall in all cases be deemed to be his or her Beneficiary unless (i) the Participant has filed an Approved Form of Election designating a non-Spouse Beneficiary, (ii) the Spouse of the Participant has consented in writing to such designation, (iii) the consent acknowledges the effect of the designation and is witnessed by a notary public, and (iv) such election designates a Beneficiary that may not be changed without further spousal consent, unless the Spouse executed a general written consent expressly permitting changes of the Beneficiary without any requirement of further consent of the Spouse. Notwithstanding the foregoing, the spousal consent requirements shall not apply if the Participant establishes to the

-47- satisfaction of the Committee that such written consent may not be obtained because there is no Spouse, the Spouse cannot be located, or other circumstances (as described in Treasury Regulations under Code Sections 401(a)(11) and 417) preclude the necessity of the Spouse’s consent. If the Spouse of a Participant is legally incompetent to give consent, such consent may be given by the Spouse’s legal guardian, which shall include the Participant if he or she is the Spouse’s legal guardian. If the Participant is legally separated or has been abandoned, as provided by a court order, spousal consent shall not be required, except where required provided by a Qualified Domestic Relations Order. Upon a Participant’s death, a Beneficiary may designate a secondary Beneficiary or Beneficiaries to receive payment of the Participant’s Accounts upon the primary Beneficiary’s death. Such designation must be made on an Approved Form of Election prior to entire payment of the Participant’s Accounts. If a deceased Participant failed to designate a Beneficiary as provided above, or if the Beneficiary dies before the Participant or before complete payment of the Participant’s Accounts, the Participant’s Accounts shall be distributed in the following order. (a) To the Participant’s surviving Spouse (determined as of the date of the Participant’s death). (b) If Paragraph (a) does not apply because the Participant does not have a Spouse on the date of his or her death, to the legal representative or representatives of the estate of the last to die of the Participant and the Participant’s designated Beneficiary (the “Surviving Payee”) or, if an estate is not opened on behalf of the Participant or Beneficiary, to the duly authorized individual properly designated by any applicable small estate affidavit or similar documentation issued pursuant to applicable state law. (c) If an estate is not opened on behalf of the Surviving Payee, to the duly authorized individual properly designated by any applicable small estate affidavit or similar documentation issued pursuant to applicable state law. (d) If there is no duly authorized individual properly designated by any applicable small estate affidavit or similar documentation issued pursuant to applicable state law, to or for the benefit of one or more of the Surviving Payee’s relatives by blood, adoption or marriage in such proportions as the Committee (or its delegate) determines. 10.5 Minimum Distribution Requirements Notwithstanding any provision of the Plan to the contrary, with respect to distributions made for calendar years beginning on or after January 1, 2003, the Plan shall apply the minimum distribution requirements of Code Section 401(a)(9) in accordance with final and temporary Treasury Regulations under Code Section 401(a)(9) that were issued by the Internal Revenue Service on April 17, 2002 and June 15, 2004 (as corrected on November 22, 2004), including Treasury Regulation Sections 1.401(a)(9)-2 through 1.401(a)(9)-9 and the incidental death benefit requirements of Code Section 401(a)(9)(G). Any provisions of the Plan that are

-48- inconsistent with Code Section 401(a)(9) and the Treasury Regulations thereunder shall be deemed inoperative. The Participant’s entire interest shall be distributed, or begin to be distributed, to the Participant no later than the Participant’s required beginning date, which is generally the later of the April 1 following the Participant’s attainment of age 70½ or the date the Participant has a Severance From Service. However, if the Participant is a 5% owner, Plan distributions must commence no later than the April 1 following the Participant’s attainment of age 70½. Benefits must be paid over a period not extending beyond the life expectancy of the Participant or the joint life expectancies of the Participant and his or her Beneficiary. If the Participant dies after installment distributions have begun, payments shall continue under the elected payment form. If the Participant dies before distributions begin, the Participant’s entire interest shall be distributed, or begin to be distributed, no later than the following: (a) If the Participant’s surviving Spouse is the Participant’s sole Beneficiary, distributions to the surviving Spouse shall 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 70½, if later. (b) If the Participant’s surviving Spouse is not the Participant’s sole Beneficiary, distributions to the Beneficiary shall 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 shall be distributed by December 31 of the calendar year containing the fifth anniversary of the Participant’s death. If the Participant’s Spouse is the sole Beneficiary and dies after the Participant but before distributions have begun, then Paragraphs (b) and (c) above shall apply as if the Spouse were the Participant. Notwithstanding any provision of this Subsection to the contrary, effective as of January 1, 2009, a Participant or Beneficiary who would have been required to receive required minimum distributions for 2009 but for the enactment of Code Section 401(a)(9)(H) (“2009 RMDs”), and who would have satisfied that requirement by receiving distributions that are (i) equal to the 2009 RMDs or (ii) one or more payments in a series of substantially equal distributions (that include the 2009 RMDs) made at least annually and expected to last for the life (or life expectancy) of the Participant or the joint lives (or joint life expectancy) of the Participant and the Participant’s designated Beneficiary, or for a period of at least ten years (“Extended RMDs”), shall receive those distributions for 2009 unless the Participant or Beneficiary chooses not to receive such distributions. Participants and Beneficiaries described in the preceding sentence shall be given the opportunity to elect not to receive the distributions described in the preceding sentence. In addition, 2009 RMDs and Extended RMDs shall be treated as Eligible Rollover Distributions under Subsection 10.3, but shall not be eligible for a direct rollover.

-49- 10.6 Missing Persons The Employers and the Committee shall not be required to search for or locate a Participant, Spouse, Alternate Payee or Beneficiary. Each Participant, Spouse, Alternate Payee, and Beneficiary must file with the Committee from time to time in writing his or her post office address and each change of post office address. Any communication, statement, or notice addressed to a Participant, Spouse, Alternate Payee, or Beneficiary at the last post office address filed with the Committee, or if no address is filed with the Committee, then in the case of a Participant, at the Participant’s last post office address as shown on the Employers’ records, shall be considered a notification for purposes of the Plan and shall be binding on the Participant, Spouse, Alternate Payee and Beneficiary for all purposes of the Plan. If the Committee notifies a Participant, Spouse, Alternate Payee, or Beneficiary, and if such person fails to claim Plan benefits or make such person’s whereabouts known to the Committee within two years after the notification, the benefits of the Participant, Spouse, or Beneficiary may be disposed of, to the extent permitted by applicable law, by one or more of the following methods: (a) By retaining such benefits in the Plan; (b) By paying such benefits to a court of competent jurisdiction for judicial determination of the right thereto; (c) By forfeiting such benefits in accordance with procedures established by the Committee. If a Participant, Spouse, Alternate Payee or Beneficiary is subsequently located, such benefits shall be restored to the Participant, Spouse, Alternate Payee or Beneficiary under the Plan; or (d) By any equitable manner permitted by law under rules adopted by the Committee. 10.7 Recovery of Benefits In the event a Participant, Spouse, Alternate Payee, or Beneficiary receives a benefit payment from the Plan that is in excess of the benefit payment that should have been made to such Participant, Spouse, Alternate Payee, or Beneficiary or in the event a person other than a Participant, Spouse, Alternate Payee, or Beneficiary receives an erroneous payment from the Plan, the Committee shall have the right, on behalf of the Plan, to recover the amount of the excess or erroneous payment from the recipient. To the extent permitted under applicable law, the Committee may, at its option, deduct the amount of such excess or erroneous payment from any future benefits payable on behalf of a Participant, regardless of whether such amount would otherwise be paid to a Participant, Spouse, or Alternate Payee, Beneficiary who did not receive the overpayment. 10.8 Facility of Payment When a person entitled to benefits under the Plan is under legal disability, or, in the Committee’s opinion, is in any way incapacitated so as to be unable to manage his or her financial affairs, the Committee may direct the Trustee to pay the benefits to such person’s legal representative, or to a relative or friend of such person for such person’s benefit, or the Committee may direct the application of such benefits for the benefit of such person. Any

-50- payment made in accordance with the preceding sentence shall be a full and complete discharge of any liability for such payment under the Plan.

-51- SECTION 11 IN-SERVICE WITHDRAWALS 11.1 Hardship Withdrawals A Participant may, prior to his or her Severance From Service, apply for a hardship withdrawal of all or any part of his or her Pre-Tax Account (excluding earnings credited on Pre- Tax Contributions after December 31, 1988), Rollover Account, After-Tax Rollover Account and Prior Plan ESOP Account, as applicable. Notwithstanding the foregoing, effective as of October 1, 2010, each Participant who was a participant in the VESystems 401(k) Plan on or before October 1, 2010 may apply for a hardship withdrawal of all or any part of his or her vested Account balances transferred from the VESystems 401(k) Plan. If a hardship withdrawal is made pursuant to this Subsection, the Participant may not make Pre-Tax, Catch-Up, or After- Tax Contributions for a period of six months following the date he or she receives the payment. A hardship withdrawal must be for an immediate and heavy financial need of the Participant for which funds are not reasonably available from other resources of the Participant. A Participant shall be deemed to have an immediate and heavy financial need if the hardship is on account of: (a) Payment of unreimbursed medical expenses described in Code Section 213(d) (determined without regard to whether the expenses exceed 7.5% of adjusted gross income) previously incurred by the Participant, his or her Spouse, any dependents of the Participant (as defined in Code Section 152 without regard to Code Sections 152(b)(1), (b)(2), and (d)(1)(B)), including any non-custodial child who is subject to the special rule of Code Section 152(e), or Primary Beneficiary, or payment of unreimbursed expenses necessary for these persons to obtain medical care described in Code Section 213(d); (b) Purchase (excluding mortgage payments) of the principal residence of the Participant; (c) Payment of tuition, related educational fees, and room and board expenses, for the next twelve months of post-secondary education for the Participant, his or her Spouse, the Participant’s dependents (as defined in Code Section 152 without regard to Code Sections 152(b)(1), (b)(2), and (d)(1)(B)), or Primary Beneficiary; (d) Prevention of the eviction of the Participant from his or her principal residence or prevention of the foreclosure on the mortgage on his or her principal residence; (e) Payment of burial or funeral expenses for the Participant’s deceased parent, Spouse, children, dependents (as defined in Code Section 152 without regard to the change in definition under Code Section 152(d)(1)(B)), or Primary Beneficiary; (f) Payment of expenses for the repair of damage to the Participant’s principal residence that would qualify for the casualty deduction under Code Section 165

-52- (determined without regard to whether the loss exceeds 10% of adjusted gross income); or (g) Other events provided for in revenue rulings, notices or other documents of general applicability published by the Commissioner of Internal Revenue. For purposes of this Subsection, “Primary Beneficiary” means an individual who a Participant has named as his or her Beneficiary under Subsection 10.4 and who has an unconditional right to all or a portion of the Participant’s Account balances upon the Participant’s death (a contingent or secondary Beneficiary does not qualify). A Participant shall be deemed to have established that the amount is not reasonably available from other resources if the Participant has elected to receive a cash distribution of the dividends paid on the shares of Federal Signal Common Stock attributable to his or her proportionate interest in the Federal Signal Stock Fund and has obtained all other in-service withdrawals, distributions and nontaxable loans available under this Plan and any other plan maintained by his or her Employer. The Committee shall determine whether a financial hardship exists and the amount to be paid as a result of the hardship. When making this determination, the Committee may rely on the Participant’s written representation that his or her immediate and heavy financial need could not be satisfied in whole or in part from other resources reasonably available to him or her. Financial hardship determinations shall be made in accordance with the Code and the applicable Treasury Regulations and using a uniform and nondiscriminatory standard. If the Committee or its designee approves the hardship withdrawal, the hardship withdrawal shall not exceed the amount required to meet the need created by the hardship, including any amounts necessary to pay any Federal income taxes or penalties reasonably anticipated to result from the withdrawal. Notwithstanding any provision of the Plan to the contrary, a Participant who is also a participant in the Federal Signal Corporation Savings Restoration Plan may not request a hardship withdrawal under this Subsection. 11.2 Withdrawals Upon Attainment of Age 59½ Before a Severance From Service, but after attainment of age 59½, a Participant may withdraw of all or any portion of the balance in his or her Pre-Tax Account. Notwithstanding the foregoing, effective as of October 1, 2010, a Participant who was a participant in the VESystems 401(k) Plan on or before such date may also withdraw all or any portion of his or her Account balances transferred from the VESystems 401(k) Plan after attainment of age 59½. 11.3 Withdrawals Upon Attainment of Normal Retirement Age Before a Severance From Service, but after attainment of Normal Retirement Age, a Participant may withdraw of all or any portion of the balances in his or her Accounts.

-53- 11.4 Withdrawals From After-Tax Account Before a Severance From Service, a Participant may withdraw all or any portion of the balances in his or her After-Tax Account once per calendar year. If the Participant withdraws After-Tax Contributions made to the Plan before January 1, 1987, the withdrawal shall come first from the Participant’s After-Tax Contributions, and then, once all of such contributions have been withdrawn, from the investment earnings on such contributions. If the Participant withdraws After-Tax Contributions made to the Plan after December 31, 1986, the withdrawal shall come, pro rata, from both the Participant’s After-Tax Contributions and the investment earnings on those contributions. 11.5 Withdrawals From Rollover Account and After-Tax Rollover Account Before a Severance From Service, a Participant may withdraw all or any portion of the balances in his or her Rollover Account and After-Tax Rollover Account once per calendar year. 11.6 Withdrawals From Balances Transferred from a Prior Plan Before a Severance From Service, a Participant who was a participant in the PIPs Technology, Inc. 401(k) Plan (the “PIPs Plan”) on or before April 1, 2008 may withdraw all or any portion of his or her Accounts attributable to balances transferred to the Plan from the PIPs Plan if such Participant incurs a Disability. 11.7 Distributions To Individuals Performing Military Service A Participant, who receives a distribution that meets the requirements of Paragraph (a) below, shall be treated as having received a distribution under Paragraph (a) even if the distribution would also have been permitted under Paragraph (b). (a) Qualified Reservist Distributions: A Participant may withdraw all or a portion of the balances in his or her Pre-Tax Account if: (i) such Participant is a member of a reserve component (as defined in Section 101 of Title 37, United States Code) that is ordered or called to active duty after September 11, 2001, and (ii) the Participant’s tour of active duty has a duration in excess of 179 days or an indefinite period. This withdrawal may only be made during the period that begins on the date of the Participant’s order or call to active duty and ends on the date of the Participant’s active duty. (b) Distributions Related to Deemed Severance From Service: During any period in which the Participant is performing qualified military service described in Code Section 414(u)(5) for more than 30 days, the Participant shall be treated as having incurred a Severance From Service for purposes of receiving a distribution from his or her Pre-Tax Account. If such Participant elects to receive a distribution from his or her Pre-Tax Account, the Participant cannot make Pre-Tax, Catch-Up or After-Tax Contributions for six months following election and payment of such distribution.

-54- 11.8 Application for In-Service Withdrawals An application for any in-service withdrawal under this SECTION 11 must be made through an Approved Form of Election. The minimum amount of any in-service withdrawal is $300. Any withdrawal payment shall be made as soon as practicable.

-55- SECTION 12 LOANS 12.1 Terms and Conditions of Loans Pursuant to procedures the Committee shall establish for loan applications and processing, the Committee may approve loans to Participants, subject to the following terms and conditions. (a) Any application for a loan must be made through an Approved Form of Election. (b) A loan shall be evidenced by a promissory note in a form approved by the Committee and shall provide for repayment over a fixed period and interest at the prevailing rate, which payment period and interest rate shall be determined by the Committee in a uniform manner. (c) At any one time, a Participant may not have outstanding more than one loan. (d) The Participant shall pledge a portion of his or her vested Accounts as security for such loan, and shall pay from such Accounts all reasonable fees related to the processing of any loan. (e) The Committee may permit loan rollovers in cases of acquisitions or dispositions for certain groups during certain periods. 12.2 Amount of Loans The principal amount of any loan made to a Participant, together with the unpaid balance of any other outstanding loans under the Plan and all other qualified employer plans (as defined in Code Section 72(p)(4)) sponsored by a Related Employer, on the date the loan is made, shall not exceed the lesser of (a) or (b) below: (a) $50,000, reduced by the excess (if any) of: (i) the highest outstanding balance of loans under the Plan and all other qualified employer plans during the twelve- month period ending the day before such loan was made, minus (ii) the outstanding balance of such outstanding loans on the date on which such loan was made; or (b) One-half of the total balance of the Participant’s vested Accounts. The minimum loan amount to a Participant shall not be less than $1,000. 12.3 Repayment of Loans A loan shall specify a repayment period that shall not extend beyond five years after the date the loan is made, unless the proceeds of the loan are used to purchase the Participant’s

-56- principal place of residence, in which case such loan must be repaid within ten years after the date the loan is made. Repayment of each loan shall be made by payroll deduction. Each loan shall require substantially level amortization with payments not less frequently than quarterly. Prepayment of all or a portion of the loan is permitted at any time without penalty by certified check or money order made payable to the Trustee. Pursuant to rules established by the Committee, if a Participant is on an unpaid Approved Leave of Absence, he or she may be permitted to defer repayments for up to one year, and may be given a grace period to repay the loan if a payment is missed. Notwithstanding the foregoing, if a Participant is on an Approved Leave of Absence due to qualified military service, his or her loan repayments may be suspended in accordance with Code Section 414(u)(4), and for the duration of his or her qualified military service, the interest rate on his or her outstanding loan shall be capped at the lesser of the original loan rate or 6%. Loan repayments shall be credited to the Participant’s Accounts from which the loan was made as of the date such payment is received by the Trustee on a pro rata basis. Loan repayments shall be credited to the Investment Funds in accordance with the Participant’s investment election under Subsection 6.2 in effect at the time of loan repayment, and, in the absence of such investment election, to the default investment arrangement specified by the Investment Committee in accordance with ERISA Section 404(c)(5) and related regulations. 12.4 Unpaid Loans A loan which is not repaid when due shall be deemed to be in default and shall be treated as a “deemed distribution” if not repaid within the cure period specified in uniform rules and guidelines established by the Committee. Upon distribution of a Participant’s Accounts before a loan is repaid in full, the unpaid loan balance, together with loan interest, shall become due and payable, and the Trustee shall first satisfy the indebtedness from the Participant’s Account before making any payments to Participant. If a loan defaults, foreclosure on the promissory note and attachment of security on such loan shall not occur until a distributable event occurs under the Plan.

-57- SECTION 13 ADMINISTRATION OF PLAN 13.1 Plan Administrator The Fiduciaries shall have only those specific powers, duties, responsibilities and obligations as are specifically given them under this Plan or the Trust Agreement or delegated to them by the Company. The Company may delegate all or any part of its powers, rights and duties under the Plan to such person or persons as it may deem advisable, including the Benefits Planning Committee, the Committee, the Investment Committee, the Trustee, and such other individuals or entities determined by the Company.

To the maximum extent permitted by law, each Fiduciary shall be responsible for the proper exercise of its own powers, duties, responsibilities and obligations under this Plan and shall not be responsible for any act or failure to act of another Fiduciary. To the maximum extent permitted by ERISA, no other Fiduciary shall be liable for any loss which may result from a decision of an investment manager with respect to Plan assets under its control. 13.2 Indemnification To the maximum extent permitted by law, the Fiduciaries, those persons to whom a Fiduciary properly delegates any portion of its responsibilities under the Plan and any persons who were, are or become directors, officers or employees of any Employer, and each of them, shall be indemnified and saved harmless by the Employers (to the extent not indemnified of saved harmless under any liability insurance contracts or indemnification arrangements) from and against any and all liability or claim to which the Fiduciaries or such other persons may be subjected by reason of any act done or omitted to be done in good faith with respect to Plan administration other than any liability or claim resulting from such person’s gross negligence or willful misconduct. Such indemnification shall include, but not be limited to, all expenses reasonably incurred in their defense in the event that the Employers failed to provide such defense after having been requested in writing to do so. 13.3 Organization of Committee The Vice President, Human Resources shall act as Chairman of the Committee.

A majority of the members of the Committee at the time in office shall constitute a quorum for the transaction of business. All resolutions adopted or other action taken by the Committee shall be by vote of a majority of the members of the Committee present at any meeting.

-60- 13.6 Reports The Committee shall prepare an annual report showing in reasonable detail the assets of the Plan and giving a brief account of the operation of the Plan for the preceding Plan Year. The Committee shall exercise such authority and responsibility as it deems appropriate in order to comply with ERISA, the Code and applicable governmental regulations relating to records of Participants’ employment, Accounts and the percentages thereof which are vested under the Plan; notifications to Participants; annual reports to the Department of Labor; and any and all other reports necessary or desirable to maintain the tax-qualified status of the Plan. 13.7 Information Required by Committee The Employers shall furnish the Committee with such data and information as the Committee may deem necessary or desirable in order to administer the Plan. The records of the Employers as to an Employee’s or Participant’s period of employment, termination of employment and the reason therefore, Approved Leave of Absence, reemployment, date of birth, marital status and compensation shall be conclusive on all persons unless determined to the Committee’s satisfaction to be incorrect. 13.8 Allocations and Delegations of Responsibility The Committee may delegate from time to time to such person or persons as it may deem advisable for the efficient administration of the Plan and Trust all or part of the Committee’s powers, rights, and duties under the Plan and the Trust and may authorize such person to delegate such powers, rights, and duties to other person or persons. Any such delegation may be made to an individual, a committee, or subcommittee established by the Committee, a third party, or any other entity selected by the Committee. The Committee at any time may modify or revoke any such delegation. Any action of a delegatee in the exercise of its delegated responsibilities shall have the same force and effect for all purposes hereunder as if such action had been taken by the Committee. Except as otherwise provided by applicable law, the Committee shall not be liable for any acts or omissions of any such delegatee. The delegatee shall periodically report to the Committee concerning the discharge of its delegated responsibilities. Unless otherwise provided, references in the Plan to the Committee shall include delegatees and designees of the Committee. 13.9 Interested Committee Member If a member of the Committee (or one of its delegatees or designees) also is a Participant in the Plan, he or she may not decide or determine any matter or question concerning distributions of any kind to be made to him or her or the nature or mode of settlement of his or her benefits unless such decision or determination could be made by him or her under the Plan if he or she were not serving on the Committee. 13.10 Removal or Resignation The Committee, or any member thereof, shall hold office until the earlier of (i) his or her termination of employment with the Company, or (ii) until the date that the Committee charter is amended to remove the person from membership of the Committee.

Unless paid by the Employers and except as otherwise provided below, all reasonable costs, charges, and expenses incurred in the administration of this Plan, including expenses incurred by the Committee, compensation to the Trustee, compensation to an investment manager, and any compensation to agents, attorneys, actuaries, accountants, recordkeepers, and other persons performing services on behalf of this Plan or for the Committee shall be paid from the Trust Fund in such portions as the Committee may direct. As directed by the Committee, expenses to be paid from the Trust Fund may be drawn from (i) Participants’ Accounts, in the form of a flat fee, charges for specific services, or a percentage of the value of each Account, (ii) earnings or gains in each Investment Fund or (iii) forfeitures under Subsection 9.7. Expenses directly related to the investment of a particular Investment Fund (such as brokerage, postage, express and insurance charges, and transfer taxes) shall be paid from that Investment Fund. 13.12 Uniform Application of Rules The Committee shall administer the Plan on a reasonable basis. Any rules, procedures, or regulations established by the Committee shall be applied uniformly to all persons similarly situated. 13.13 Committee’s Decision Final Benefits under the Plan shall be paid only if the Committee, or its delegate, decides in its sole discretion that a Participant or Beneficiary (or other claimant) is entitled to them. Subject to applicable law, any interpretation of the provisions of the Plan and any decisions on any matter within the discretion of the Committee made by the Committee, or its delegate, in good faith shall be binding on all persons. A misstatement or other mistake of fact shall be corrected when it becomes known and the Committee shall make such adjustment on account thereof as it considers equitable and practicable.

-62- SECTION 14 CLAIMS PROCEDURES 14.1 Initial Retirement Benefit Claims In the event of a dispute between the Trustee or Committee and a Participant or Beneficiary over the amount of benefits payable under the Plan, the Participant or Beneficiary may file a claim for benefits by notifying the Committee of such claim. Such notification must be in writing and shall set forth the basis of such claim. The Committee shall decide whether to grant a claim within 90 days of the date on which the claim is received, unless special circumstances require a longer period for review of the claim, and the claimant is notified in writing of the extension of time within the first 90-day period; provided, however, that no extension shall be longer than an additional 90 days beyond the original response deadline. 14.2 Initial Disability Benefit Claims If the claim is for Disability benefits, the Committee shall review the claim within 45 days of the date on which the claim is received. If special circumstances require a longer period for review, and the claimant is notified in writing of the extension of time within the 45-day period, the Committee may extend the time period for responding to the claim by an additional 30 days. If a decision still cannot be made within this 30-day extension period due to circumstances outside the Committee’s control, the Committee may extend the time period for responding to the claim by an additional 30 days, provided that the Committee notifies the claimant in writing of such additional extension prior to the expiration of the original 30-day extension period. 14.3 Initial Claim Processing and Appeal If a claimant has not submitted sufficient information to the Committee to process a benefit claim, the claimant shall be notified of the incomplete claim and given time to submit additional information. This shall extend the time in which the Committee has to respond to the claim from the date the notice of insufficient information is sent to the claimant until the date the claimant responds to the request. If the claimant does not submit the requested missing information to the Committee within a reasonable time period, the claim shall be denied. Whenever a claim for benefits is denied, written notice, prepared in a manner calculated to be understood by the claimant, shall be provided to the claimant, setting forth the specific reasons for the denial, referring to the specific Plan provisions on which the denial is based, explaining the procedures for review of the decision made by the Committee, and explaining the claimant’s right to bring a civil action under ERISA Section 502(a) following a denial on appeal. If the denial is based upon submission of information insufficient to support a decision, the Committee shall specify the information which is necessary to perfect the claim and its reasons for requiring such additional information. Benefits shall be paid only if the Committee determines in its discretion that a claimant is entitled them.

-63- Any request for review must be in writing and shall be addressed to the Committee. The request for review shall set forth all of the grounds upon which it is based, all facts in support thereof, and any other matters which the claimant deems pertinent. The Committee may require the claimant to submit such additional facts, documents, or other material as the Committee may deem necessary or appropriate in making its review. 14.4 Appeal Procedures for Retirement Benefits Any individual whose claim for benefits is denied in whole or in part (or such person’s authorized representative) may appeal the denial by submitting to the Committee a written request for review of the application within 60 days after receiving written notice of the denial from the Committee. The Committee shall give the claimant (or the claimant’s representative) an opportunity to review pertinent documents and to submit written comments and other information (even if such information was not submitted in connection with the initial claim) in preparing such request for review. The Committee shall act upon each request for review within 60 days after receipt thereof unless special circumstances require an extension of time of up to an additional 60 days for processing the request for review. If such an extension of time for review is required, written notice of the extension shall be furnished to the claimant prior to the end of the initial 60-day period; provided, however that such review shall be made no later than 120 days after the Committee’s receipt of the claimant’s written request for review. 14.5 Appeal Procedures for Disability Benefits Any individual whose application for Disability benefits is denied in whole or in part (or such person’s authorized representative) may appeal the denial by submitting to the Committee a written request for review of the application within 180 days after receiving written notice of the denial from the Committee. The Committee shall give the claimant (or the claimant’s representative) an opportunity to review pertinent documents and to submit written comments and other information (even if such information was not submitted in connection with the initial claim) in preparing such request for review. The Committee shall act upon each request for review of a Disability claim within 45 days after receipt thereof unless special circumstances require an extension of time of up to an additional 45 days for processing the request for review. If such an extension of time for review is required, written notice of the extension shall be furnished to the claimant prior to the end of the initial 45-day period; provided, however that such review shall be made no later than 90 days after the Committee’s receipt of the claimant’s written request for review. 14.6 Appeals Processing Within the applicable time periods described above, the Committee shall give written notice of its appeal decision to the claimant. In the event the Committee confirms the denial of the application for benefits in whole or in part, such notice shall set forth, in a manner calculated to be understood by the claimant, the specific reasons for such denial, specific references to the Plan provisions on which the decision was based, a statement that the claimant is entitled to receive, upon request and free of charge, access to and copies of all documents, records, and

-64- other information relevant to the benefit claim, and a statement regarding the claimant’s right to bring a civil action under ERISA Section 502(a) following a denial on appeal. In the event that the Committee determines that the claim for benefits should not have been denied in whole or in part, the Committee shall take appropriate remedial action. The Committee shall establish rules and procedures, consistent with the Plan and with ERISA, as it may deem necessary or appropriate in carrying out its responsibilities under this Section. The Committee may require a claimant who wishes to submit additional information in connection with a claim or appeal to do so at the claimant’s own expense. No action at law or in equity shall be brought to recover benefits under the Plan until the claim and review process in this SECTION 14 has been exercised and until the Plan benefits requested in such review have been denied in whole or in part. If any judicial proceeding is undertaken to appeal the denial of a claim or bring any other action under ERISA other than a breach of fiduciary duty claim, the evidence presented shall be strictly limited to the evidence timely presented to the Committee. In addition, any such judicial proceeding must be filed no later than the earliest of (i) 90 days after the Committee’s final decision regarding the claim appeal, (ii) three years after the date on which the Participant or other claimant commenced payment of the Plan benefits at issue in the judicial proceeding, or (iii) the statutory deadline for filing a claim or lawsuit with respect to the Plan benefits at issue in the judicial proceeding as determined by applying the most analogous statute of limitations for the state of Illinois. All decisions and communications to Participants, Spouses, Beneficiaries, or other persons regarding a claim for benefits under the Plan shall be held strictly confidential by the Participant, Spouse, Beneficiary (or other claimant), and the Committee, the Employers, and their agents.

-65- SECTION 15 MANAGEMENT OF TRUSTS 15.1 Trustee and Trust Agreement All Plan assets shall be held in the Trust. The Trust shall be held by a Trustee under a Trust Agreement approved by the Committee. The Trust Agreement may provide for the joint administration, and commingling, of the Trust Fund with the funds of any other defined contribution plan established by any Related Employer. The assets of the Trust shall be held, invested and disposed of in accordance with the terms of the Trust Agreement. 15.2 Restrictions as to Reversion of Trust Fund to the Employers Except as otherwise provided in this Subsection, all assets of the Trust Fund shall be retained for the exclusive benefit of Participants, Alternate Payees, and Beneficiaries. All the Employers shall have no right, title, or interest in the assets of the Trust Fund. No part of the assets of the Trust Fund at any time shall revert to, or be repaid to, the Employers, directly or indirectly, except as follows. (a) If the Internal Revenue Service initially determines that the Plan, as applied to an Employer, does not meet the requirements of a “qualified plan” under Code Section 401(a), the assets of the Trust Fund attributable to contributions made by the Employer under the Plan shall be returned to the Employer within one year of the date of denial of qualification of the Plan as applied to the Employer. (b) If a contribution or a portion of a contribution is made by an Employer as a result of a mistake of fact, such contribution or portion of a contribution shall not be considered to have been contributed to the Trust by the Employer and, after having been reduced by any losses of the Trust allocable thereto, shall be returned to the Employer within one year of the date the amount is paid to the Trust. (c) Each contribution made by an Employer is conditioned upon the deductibility of such contribution as an expense for Federal income tax purposes, to the extent the deduction for the contribution made by the Employer is disallowed, such contribution, or portion of such contribution, after having been reduced by any losses of the Trust allocable thereto, shall be returned to the Employer within one year of the date of disallowance of the deduction. In no event may the return of a contribution pursuant to Paragraph (b) or (c) above cause any Participant’s Accounts to be less than the amount had the contribution not been made under the Plan.

-66- SECTION 16 AMENDMENT AND TERMINATION 16.1 Amendment While the Employers expect and intend to continue the Plan, the Company, by action of the Benefits Planning Committee, reserves the right to amend the Plan, in whole or in part, from time to time, except as follows: (a) The duties and liabilities of the Committee under the Plan cannot be increased substantially without its consent. (b) No amendment shall reduce the value of a Participant’s accrued benefit (as adjusted for income, losses, expenses, appreciation, and depreciation) to less than the amount he or she would be entitled to receive if the Participant had resigned from employment with all of the Employers on the effective date of the amendment. (c) Except as provided in Subsection 15.2 or required by the Code or other applicable law, under no condition shall any amendment result in the return or repayment to any Employer of any part of the Trust Fund or the income therefrom, or result in the distribution of the Trust Fund for the benefit of anyone other than Participants and any other persons entitled to benefits under the Plan. No person has the authority to modify the terms of the Plan, except by means of authorized written amendments to the Plan. No verbal or written representations contrary to the terms of the Plan and its written amendments shall be binding upon the Employers or the Plan. 16.2 Plan Termination The Plan shall terminate as to all Employers on any date specified by the Company by action of the Benefits Planning Committee with 30 days’ advance written notice of the termination given to the Committee, the Trustee, and the other Employers. The Plan shall terminate as to an individual Employer on the first to occur of the following. (a) The date the Plan is terminated by that Employer. (b) The date that Employer is judicially declared bankrupt or insolvent. (c) The date that Employer completely discontinues contributions under the Plan. (d) The date that Employer ceases to be a Related Employer due to one of the following: (i) The sale of all or substantially all of the stock of that Employer to a person that is not a Related Employer;

-67- (ii) The sale of all or substantially all of the assets of that Employer to a person that is not a Related Employer; or (iii) The merger or consolidation of that Employer with a person that is not a Related Employer. Each Participant employed by an Employer that ceases to be a Related Employer shall be considered to have terminated employment with all Related Employers on such date and shall cease to accrue additional Plan contributions with respect to any period of time commencing on or after such date. 16.3 Nonforfeitability and Distribution on Termination Upon complete termination or partial termination of the Plan, or the complete discontinuance of all Plan contributions, the rights of all affected Participants to benefits accrued to the date of such termination, after all adjustments, shall be nonforfeitable. Upon such occurrence, the Committee may direct the Trustee to distribute to each Participant employed by that Employer his or her benefits under the Plan in a lump sum (unless he or she then is employed by a Related Employer). However, distributions under this Subsection shall be made only to the extent such distributions are permissible under Code Section 401(k) and applicable Treasury Regulations. All appropriate accounting provisions of the Plan shall continue to apply until all Participants’ Accounts have been distributed under the Plan. 16.4 Plan Merger, Consolidation, or Spin-Off In the case of any merger or consolidation with, or transfer of assets or liabilities to, any other retirement plan qualified under Code Section 401(a), each Participant’s benefit shall be equal to or greater than the benefit he or she would have been entitled to receive if the Plan had terminated immediately before the merger, consolidation, or transfer. If an operating unit of an Employer is sold and the purchaser agrees to a spin-off from the Plan, the Plan Accounts of Employees of such unit shall be transferred to a successor funding arrangement.

-68- SECTION 17 MISCELLANEOUS 17.1 Non-Alienation of Benefits The interests of persons entitled to benefits under the Plan are not subject to their debts or other obligations and, except as may be required by the tax withholding provisions of the Code or any state’s income tax act or pursuant to a Qualified Domestic Relations Order. Plan benefits may not be voluntarily or involuntarily sold, transferred, alienated, assigned, or encumbered. 17.2 Absence of Guaranty Neither the Committee, the Trustee, nor any Employer in any way guarantees the Trust Fund from loss or depreciation. Except as required by applicable law, the Committee and the Employers do not guarantee any payment to any person. The liability of a Trustee or the Committee to make any payment under the Plan shall be limited to the assets held by the Trustee which are available for that purpose. 17.3 Employment Rights The Plan does not constitute a contract of employment, and participation in the Plan shall not give any Employee the right to be retained in the employ of any Employer (or any Related 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. 17.4 Litigation by Participants or Other Persons If a legal action begun against a Fiduciary, a Related Employer, or any person or persons to whom the Fiduciary has delegated all or part of its duties hereunder, by or on behalf of any person results adversely to that person, or if a legal action arises because of conflicting claims to a Participant’s or other person’s benefits, the cost to the Fiduciary, a Related Employer, or any person or persons to whom the a Fiduciary has delegated all or part of its duties hereunder of defending the action shall be charged to the Accounts of individuals or Participants involved in the action to the extent permitted by law. 17.5 Evidence Evidence required of anyone under the Plan may be by certificate, affidavit, document, or other information that the person acting on it considers pertinent and reliable, and signed, made, or presented by the proper party or parties. 17.6 Waiver of Notice Any notice required under the Plan may be waived by the person entitled to such notice.

-69- 17.7 Controlling Law Except to the extent superseded by laws of the United States, the laws of Illinois shall be controlling in all matters relating to the Plan. 17.8 Statutory References Any reference in the Plan to a section of the Code or ERISA, or to a section of any other Federal law, shall include any comparable section or sections of any future legislation that amends, supplements, or supersedes that section. 17.9 Severability In case any provision of the Plan shall be held illegal or invalid for any reason, such illegality or invalidity shall not affect the remaining provisions of the Plan, and the Plan shall be construed and enforced as if such illegal and invalid provision had never been set forth in the Plan. 17.10 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, by resolution of a duly authorized committee of its board of directors, or by a person or persons authorized by resolution of its board of directors or such committee. 17.11 Gender and Number Where the context permits, words in the masculine gender shall include the feminine and neuter genders, the singular shall include the plural, and the plural shall include the singular. 17.12 Examination of Documents Copies of the Plan and Trust, and any amendments thereto, are on file at the office of the Company where they may be examined by any Participant or other person entitled to benefits under the Plan during normal business hours. 17.13 Manner of Delivery Each notice or statement provided to a Participant shall be delivered in any manner established by the Committee and in accordance with applicable law, including, but not limited to, electronic delivery. 17.14 Effect on Other Benefits Except as otherwise specifically provided under the terms of any other employee benefit plan of an Employer, a Participant’s participation in this Plan shall not affect the benefits provided under such other employee benefit plan.

-70- 17.15 Headings The headings of Sections, Subsections, and Paragraphs are included solely for reference and convenience and are not intended to modify or otherwise affect the text of the Plan. 17.16 No Third-Party Beneficiaries The Plan constitutes the entire agreement of the parties and supersedes all prior agreements and undertakings, both written and oral, between the parties, or any of them, with respect to the subject matter hereof and are not intended to confer upon any other person any rights or remedies hereunder.

-71- SECTION 18 TOP HEAVY RULES 18.1 Purpose and Effect The purpose of this SECTION 18 is to comply with the requirements of Code Section 416. The provisions of this Section shall be effective for each Plan Year in which the Plan is a “Top-Heavy Plan” within the meaning of Code Section 416(g); provided, however, that this Section shall apply with respect to only those Participants whose employment is not subject to a collective bargaining agreement between the Employers and a union that provides for their participation in the Plan. 18.2 Top Heavy Plan In general, the Plan shall be a Top-Heavy Plan for any Plan Year if, as of the last day of the preceding Plan Year (the “Determination Date”), the aggregate Accounts of Participants who are Key Employees (as defined in Subsection 18.3) exceed 60% of the aggregate Accounts of all Participants. In making the foregoing determination, the following rules shall apply. (a) A Participant’s Accounts shall be increased by the aggregate distributions, if any, made with respect to the Participant during the one-year period ending on the Determination Date (including distributions under a terminated plan which, had it not been terminated, would have been aggregated with this Plan under Code Section 416(g)(2)(A)(i)). In the case of a distribution made for a reason other than Severance From Service, death or Disability, the one-year period shall be replaced with a five-year period. (b) The Account of, and distributions to, a Participant who was previously a Key Employee, but who is no longer a Key Employee, shall be disregarded. (c) The Account of a Beneficiary of a Participant shall be considered the Account of a Participant. (d) The Account of a Participant who did not perform any services for the Employers during the one-year period ending on the Determination Date shall be disregarded. (e) Any Catch-Up Contributions or any Rollover Contributions (or similar transfer) from a plan maintained by a corporation other than a Related Employer shall not be taken into account as part of the Participant’s aggregate Accounts. 18.3 Key Employee In general, a “Key Employee” is an Employee or former Employee (including any deceased Employee) who, at any time during the Plan Year that includes the Determination Date, was:

-72- (a) An officer of a Related Employer receiving annual Code Section 415 Compensation greater than $170,000 (as adjusted under Code Section 416(i)(l)); (b) A 5% owner of a Related Employer; or (c) A 1% owner of a Related Employer receiving annual Code Section 415 Compensation from any of the Related Employers of more than $150,000. The determination of who is a Key Employee shall be made in accordance with Code Section 416(i)(1) and the Treasury Regulations and other guidance issued thereunder. 18.4 Minimum Vesting For any Plan Year in which the Plan is a Top-Heavy Plan and each subsequent Plan Year, a Participant who has completed at least three years of Vesting Service shall be 100% vested in his or her Accounts. 18.5 Minimum Employer Contribution For any Plan Year in which the Plan is a Top-Heavy Plan, the Employer contribution, if any, credited to each Participant who is not a Key Employee shall not be less than 3% of such Participant’s Code Section 415 Compensation for that year. Notwithstanding the foregoing, in no event shall an Employer contribution credited in any year to a Participant who is not a Key Employee (expressed as a percentage of such Participant’s Code Section 415 Compensation) exceed the maximum Employer contribution credited in that year to a Key Employee (expressed as a percentage of such Key Employee’s Code Section 415 Compensation). For purposes of the foregoing, Pre-Tax, Catch-Up, and After-Tax Contributions shall not be considered Employer contributions, but Matching Contributions shall be considered Employer contributions and shall be taken into account for purposes of satisfying the minimum contribution requirements of Code Section 416(c)(2) and the Plan. The preceding sentence shall apply with respect to any Matching Contributions under the Plan or, if the Plan provides that the minimum contribution requirement shall be met in another plan (including another plan that meets the requirements of Code Section 401(k)(12) and/or the requirements of Code Section 401(m)(11)), such other plan. Matching Contributions that are used to satisfy the minimum contribution requirements shall be treated as Matching Contributions for purposes of Subsection 8.5 and the other requirements of Code Section 401(m). If an Employer maintains more than one plan, the minimum Employer contribution otherwise required under this Subsection may be reduced in accordance with Treasury Regulations to either coordinate the minimum Employer contribution or prevent inappropriate duplications of minimum contributions or benefits. 18.6 Aggregation of Plans Each other defined contribution plan and defined benefit plan maintained by the Related Employers that covers a Key Employee as a participant, or that is maintained by the Related Employers in order for a Plan covering a Key Employee to qualify under Code Sections

-73- 401(a)(4) and 410, shall be aggregated with this Plan in determining whether this Plan is a Top- Heavy Plan. In addition, any other defined contribution plan or defined benefit plan of the Related Employers may be included if all such plans which are included when aggregated shall continue to qualify under Code Sections 401(a)(4) and 410.
