2. AMENDMENTS OF NOTE AGREEMENTS.

2.1. Amendment to References to Federal Signal in 2002 Note Agreement.

          Each reference to “Federal Signal” in the 2002 Note Agreement is replaced with “the Company.”

2.2. Amendment to References to Restricted Subsidiaries in Note Agreements.

2.3. Interest Rates and Calculations.

          The interest rate on each series of Notes, or the calculation thereof, is modified as follows:

     (a) Commencing on the Effective Date (as hereinafter defined), the interest rate payable on the Series 1999-A Notes, Series 2001-A Notes, Series 2002-A Notes and the Guaranteed Notes shall increase by one percent (1.0%) per annum and on January 1, 2010 such interest rate shall increase by another one percent (1.0%) per annum, as set forth below:

     (b) Commencing on the Effective Date, the Applicable Percentage, as such term is used in Section 1.3(a) of the 2003 Note Agreement, for the Series 2003-A, Tranche 2, Notes and the Series 2003-A, Tranche 3, Notes shall increase by one percent (1.0%) per annum and on January 1, 2010 such Applicable Percentage shall increase by another one percent (1.0%) per annum, as set forth below:

     (c) A new Section 1A is added to the 1999 Note Agreement and the 2002 Note Agreement immediately after Section 1 of such agreements, to read in its entirety as follows:

1A. CHANGE IN RESERVE REQUIREMENTS.

          The Notes shall bear interest from time to time at the stated rate of interest (and in the manner) specified therein. Notwithstanding the foregoing, unless, pursuant to generally applicable insurance regulations for U.S. life and health insurance companies, the risk based capital factor (the “Risk Based Capital

Factor”) attributable to any of the Notes on April 1, 2010, shall be at a level below the level attributable to such Notes on the Effective Date (an “RBC Change”), the interest rate on the outstanding Notes shall be increased by an additional two percent (2.0%) per annum commencing on April 1, 2010. This increase shall be in addition to the increases provided in Section 2.3(a) of the Global Amendment. Each holder of a Note agrees that (i) if it has actual knowledge of an RBC Change prior to April 1, 2010 it will use reasonable efforts to notify the Company of such RBC change prior to April 1, 2010 and (ii) upon written request of the Company prior to April 1, 2010, it will use reasonable efforts to ascertain whether there has been an RBC Change and to advise the Company thereof.

     (d) A new Section 1A is added to the 2003 Note Agreement immediately after Section 1 of such agreement, to read in its entirety as follows:

1A. CHANGE IN RESERVE REQUIREMENTS.

          Subject to the next succeeding sentence, the Notes shall bear interest from time to time at the stated rate of interest (and in the manner) specified therein. Notwithstanding the foregoing, unless, pursuant to generally applicable insurance regulations for U.S. life and health insurance companies, the risk based capital factor (the “Risk Based Capital Factor”) attributable to any of the Notes on April 1, 2010, shall be at a level below the level attributable to such Note on the Effective Date (an “RBC Change”), the applicable percentage to be used in determining Adjusted Libor for such Notes pursuant to Section 1.3(a) shall be increased by an additional two percent (2.0%) per annum commencing on April 1, 2010. This increase shall be in addition to the increases provided in Section 2.3(b) of the Global Amendment. Each holder of a Note agrees that (i) if it has actual knowledge of an RBC Change prior to April 1, 2010, it will use reasonable efforts to notify the Company of such RBC change prior to April 1, 2010 and (ii) upon written request of the Company prior to April 1, 2010, it will use reasonable efforts to ascertain whether there has been an RBC Change and to advise the Company thereof.

     (a) Section 8.5 of the 1999 and 2002 Note Agreements, and Section 8.6 of the 2003 Note Agreement, are amended to read in their entirety as follows, except that for purposes of the 2003 Note Agreement, all references below to “8.5” shall be deemed to mean “8.6”:

8.5. Purchase of Notes.

          The Company will not and will not permit any Affiliate to purchase, redeem, prepay or otherwise acquire, directly or indirectly, any of the outstanding Notes except (a) upon the payment or prepayment of the Notes in accordance with the terms of this Agreement and the Notes or (b) pursuant to an

offer to purchase at not less than par plus accrued interest made by the Company or an Affiliate pro rata to the holders of All Notes of All Series at the time outstanding upon the same terms and conditions. Any such offer shall provide each holder with sufficient information to enable it to make an informed decision with respect to such offer, and shall remain open for at least 30 days. A failure by a holder to respond to an offer under clause (b) above or to accept any such offer as to all of such offer made to such holder, within the offer period, shall be deemed to constitute acceptance of such offer by such holder. If the holders of more than 25% of the principal amount of All Notes of All Series then outstanding accept or are deemed to have accepted such offer, the Company shall promptly notify the remaining holders of the actual percentage that have accepted and the expiration date for the acceptance by holders of Notes of such offer shall be extended by the number of days necessary to give each such remaining holder at least 10 Business Days from its receipt of such notice to accept such offer. The Company will promptly cancel all Notes acquired by it or any Affiliate pursuant to any payment, prepayment or purchase of Notes pursuant to any provision of this Agreement and no Notes may be issued in substitution or exchange for any such Notes.

     (b) The definition of “Remaining Scheduled Payments” in Section 8.6 of the 1999 and 2002 Note Agreements is amended to read in its entirety as follows:

           “Remaining Scheduled Payments” means, with respect to the Called Principal of any Note, all payments of such Called Principal and interest thereon (for this purpose only to be calculated based upon the original coupon rate on such Note) that would be due after the Settlement Date with respect to such Called Principal if no payment of such Called Principal were made prior to its scheduled due date, provided that if such Settlement Date is not a date on which interest payments are due to be made under the terms of the Notes, then the amount of the next succeeding scheduled interest payment will be reduced by the amount of interest accrued to such Settlement Date and required to be paid on such Settlement Date pursuant to Section 8.2 or 12.1.

     (c) A new Section 8.7 is added to the 1999 and 2002 Note Agreements and a new Section 8.9 is added to the 2003 Note Agreement, to read in its entirety as follows, except that for purposes of the 2003 Note Agreement, all references below to “8.7” shall be deemed to mean “8.9”:

8.7 Mandatory Offer to Prepay upon Change of Control.

     (a) Notice of Change of Control or Control Event — The Company will, within five Business Days after any Responsible Officer has knowledge of the occurrence of any Change of Control or Control Event, give notice of such Change of Control or Control Event to each holder of Notes unless notice in respect of such Change of Control (or the Change of Control contemplated by such Control Event) shall have been given pursuant to paragraph (b) of this Section 8.7. If a Change of Control has occurred, such notice shall contain and

constitute an offer to prepay Notes as described in paragraph (c) of this Section 8.7 and shall be accompanied by the certificate described in paragraph (g) of this Section 8.7.

     (b) Condition to Company Action — The Company will not take any action that consummates or finalizes a Change of Control unless (i) at least 15 Business Days prior to such action it shall have given to each holder of Notes written notice containing and constituting an offer to prepay Notes accompanied by the certificate described in paragraph (g) of this Section 8.7, and (ii) subject to the provisions of paragraph (d) below, contemporaneously with such action, it prepays all Notes required to be prepaid in accordance with this Section 8.7.

     (c) Offer to Prepay Notes — The offer to prepay Notes contemplated by paragraphs (a) and (b) of this Section 8.7 shall be an offer to prepay, in accordance with and subject to this Section 8.7, all, but not less than all, of the Notes held by each holder (in this case only, “holder” in respect of any Note registered in the name of a nominee for a disclosed beneficial owner shall mean such beneficial owner) on a Business Day specified in such offer (the “Proposed Prepayment Date”). If such Proposed Prepayment Date is in connection with an offer contemplated by paragraph (a) of this Section 8.7, such date shall be not less than 30 days and not more than 60 days after the date of such offer.

     (d) Acceptance; Rejection — A holder of Notes may accept the offer to prepay made pursuant to this Section 8.7 by causing a notice of such acceptance to be delivered to the Company on or before the date specified in the certificate described in paragraph (g) of this Section 8.7. A failure by a holder of Notes to respond to an offer to prepay made pursuant to this Section 8.7, or to accept an offer as to all of the Notes held by the holder, within such time period shall be deemed to constitute acceptance of such offer by such holder.

     (e) Prepayment — Prepayment of the Notes to be prepaid pursuant to this Section 8.7 shall be at 100% of the outstanding principal amount of such Notes, together with interest on such Notes accrued to the date of prepayment and shall not require the payment of any Make-Whole Amount or prepayment premium. The prepayment shall be made on the Proposed Prepayment Date except as provided in paragraph (f) of this Section 8.7.

     (f) Deferral Pending Change of Control — The obligation of the Company to prepay Notes pursuant to the offers required by paragraphs (a) and (b) and accepted in accordance with paragraph (d) of this Section 8.7 is subject to the occurrence of the Change of Control in respect of which such offers and acceptances shall have been made. In the event that such Change of Control does not occur on or prior to the Proposed Prepayment Date in respect thereof, the prepayment shall be deferred until and shall be made on the date on which such Change of Control occurs. The Company shall keep each holder of Notes reasonably and timely informed of (i) any such deferral of the date of prepayment, (ii) the date on which such Change of Control and the prepayment are expected to

occur, and (iii) any determination by the Company that efforts to effect such Change of Control have ceased or been abandoned (in which case the offers and acceptances made pursuant to this Section 8.7 in respect of such Change of Control shall be deemed rescinded). Notwithstanding the foregoing, in the event that the prepayment has not been made within 90 days after such Proposed Prepayment Date by virtue of the deferral provided for in this Section 8.3(f), the Company shall make a new offer to prepay in accordance with paragraph (c) of this Section 8.7.

     (c) any attachment or judgment Lien, unless the judgment it secures has not, within 60 days after the entry thereof, been discharged or execution thereof stayed pending appeal, or has not been discharged within 60 days after the expiration of any such stay;

that in the case of clauses (i), (ii) and (iii) such Liens do not extend to additional property of the Company or any Subsidiary (other than property that is an improvement to or is acquired for specific use in connection with the subject property) and, in the case of clause (ii) only, that the aggregate principal amount of Indebtedness secured by each such Lien does not exceed the lesser of the fair market value (determined in good faith by the board of directors of the Company) or cost of acquisition or construction of the property subject thereto;

     (i) Liens resulting from extensions, renewals or replacements of Liens permitted by paragraph (d), (e) and (h), provided that (i) there is no increase in the principal amount or decrease in the maturity of the Indebtedness secured thereby at the time of such extension, renewal or replacement, (ii) any new Lien attaches only to the same property theretofore subject to such earlier Lien and (iii) immediately after such extension, renewal or replacement no Default or Event of Default would exist; and

      10.5 Sale of Assets.

          Except as permitted by Section 10.6, the Company will not, and will not permit any Subsidiary to, sell, lease, transfer or otherwise dispose of, including by way of merger (collectively, a “Disposition”), any assets, including capital stock of Subsidiaries, in one or a series of transactions, to any Person, other than:

     (a) Dispositions in the ordinary course of business;

     (b) Dispositions by the Company to a Wholly Owned Subsidiary or by a Subsidiary to the Company or to another Wholly Owned Subsidiary or

     (c) other Dispositions not otherwise permitted by this Section 10.5, including the sale of receivables pursuant to asset securitization transactions, provided that the aggregate net book value of all assets so disposed of in any fiscal year pursuant to this Section 10.5(c) does not exceed 15% of Consolidated Total Assets as of the end of the immediately preceding fiscal year.

Notwithstanding the foregoing, the Company may, or may permit any Subsidiary to, make a Disposition and the assets subject to such Disposition shall not be subject to or included in the foregoing limitation and computation contained in Section 10.5(c), to the extent that the net proceeds from such Disposition (after repayment of any Indebtedness secured by a Lien on the assets subject to such Disposition) are within one year of such Disposition:

     (A) reinvested in productive assets by the Company or a Subsidiary; or

     (B) applied to the payment or prepayment of the Notes and any other outstanding Indebtedness of the Company that is pari passu or senior to the Notes.

For purposes of foregoing clause B, the Company shall offer to prepay (on a Business Day not less than 30 or more than 60 days following such offer) the Notes, on a pro rata basis with the other Indebtedness that the Company elects to include in such offer, at a price of 100% of the principal amount of the Notes to be prepaid (without any Make-Whole Amount), together with interest accrued to the date of prepayment; provided that if any holder of the Notes declines or rejects such offer, the proceeds that would have been paid to such holder shall be offered pro rata to the other holders of the Notes that have accepted the offer. A failure by a holder of Notes to respond in writing not later than 10 Business Days prior to the proposed prepayment date to an offer to prepay made pursuant to this Section 10.5 shall be deemed to constitute acceptance of such offer by such holder. Solely for the purposes of foregoing clause (B), whether or not such offers are accepted by the holders, the entire principal amount of the Notes subject thereto shall be deemed to have been prepaid.

      10.6 Merger, Consolidation, etc.

reasonably satisfactory to the Required Holders, to the effect that all agreements or instruments effecting such assumption are enforceable in accordance with their terms and comply with the terms hereof; and

     (ii) at the time of such transaction and immediately after giving effect to such transaction, no Default or Event of Default shall have occurred and be continuing; and

No such conveyance, transfer or lease of all or substantially all of the assets of the Company shall have the effect of releasing the Company or any successor corporation that shall theretofore have become such in the manner prescribed in this Section 10.6 from its liability under this Agreement or the Notes .

      10.7 Indebtedness of Subsidiaries.

          The Company will not permit any Subsidiary to create, incur, assume, guaranty or be or remain liable, contingently or otherwise, with respect to any Indebtedness other than:

      10.9 Guaranties by Subsidiaries.

          The Company will not permit any Subsidiary to become a party to the Bank Guarantees or to directly or indirectly guarantee any of the Company’s Indebtedness or other obligations under the Credit Agreement unless such Subsidiary is, or concurrently therewith becomes, a party to the Subsidiary Guaranty.

      10.10 Nature of Business.

          The Company will not, and will not permit any Subsidiary to, engage in any business if, as a result, the general nature of the business in which the Company and its Subsidiaries, taken as a whole, would then be engaged would be substantially changed from the general nature of the business in which the Company and its Subsidiaries, taken as a whole, were engaged on December 31, 2008 .
