B.           The Obligors desire to issue and sell, and the Purchasers desire to purchase, an additional series of Notes (as defined in the Note Purchase Agreement) pursuant to the Note Purchase Agreement and in accordance with the terms set forth below;

The Tranche A Notes and the Tranche B Notes shall be substantially in the forms set out in Exhibit 1(a) and Exhibit 1(b), respectively, with such changes therefrom, if any, as may be approved by the Purchaser(s) and the Obligors.

2.          Sale and Purchase of Series 2015A Notes. Subject to the terms and conditions of this Supplement and the Note Purchase Agreement and on the basis of the representations and warranties hereinafter set forth, the Obligors will issue and sell to each of the Purchasers, and each of the Purchasers will purchase from the Obligors, at the Closing provided for in Section 3, Series 2015A Notes in the principal amount specified opposite their respective names in the attached Schedule A hereto at the purchase price of 100% of the principal amount thereof. The obligations of the Purchasers hereunder are several and not joint obligations and no Purchaser shall have any liability to any Person for the performance or non-performance by any other Purchaser hereunder.

3.          Closing. The sale and purchase of the Series 2015A Notes to be purchased by each Purchaser shall occur at the offices of Xxxxxxx and Xxxxxx LLP, 000 Xxxx Xxxxxx Xxxxxx, Xxxxxxx, XX 00000 at 10:00 a.m. Chicago time, at a closing (the “Closing”) on August 20, 2015.

At the Closing, the Obligors will deliver to each Purchaser the Series 2015A Notes to be purchased by such Purchaser in the form of a single Tranche A Note and/or Tranche B Note (or such greater number of notes of each tranche, as applicable, in denominations of at least $100,000 as such Purchaser may request) dated the date of the Closing and registered in such Purchaser’s name (or in the name of such Purchaser’s nominee), against delivery by such Purchaser to the Obligors or its order of immediately available funds in the amount of the purchase price therefor by wire transfer of immediately available funds for the account of the Obligors in accordance with wire transfer instructions provided by the Company to such Purchaser pursuant to Section 4.10 of the Note Purchase Agreement. If, at the Closing, the Obligors shall fail to tender such Series 2015A Notes to any Purchaser as provided above in this Section 3, or any of the conditions specified in Section 4 shall not have been fulfilled to any Purchaser’s satisfaction, such Purchaser shall, at such Purchaser’s election, be relieved of all further obligations under this Supplement, without thereby waiving any rights such Purchaser may have by reason of such failure or such nonfulfillment.

-2-

5.          Representations and Warranties of the Obligors.

6.          Representations of the Purchasers. Each Purchaser severally represents that at least one of the following statements is an accurate representation as to each source of funds (a “Source”) to be used by such Purchaser to pay the purchase price of the Series 2015A Notes to be purchased by it hereunder:

-3-

(a)          the Source is an “insurance company general account” (as the term is defined in the United States Department of Labor’s Prohibited Transaction Exemption (“PTE”) 95-60) in respect of which the reserves and liabilities (as defined by the annual statement for life insurance companies approved by the National Association of Insurance Commissioners (the “NAIC Annual Statement”)) for the general account contract(s) held by or on behalf of any employee benefit plan together with the amount of the reserves and liabilities for the general account contract(s) held by or on behalf of any other employee benefit plans maintained by the same employer (or affiliate thereof as defined in PTE 95-60) or by the same employee organization in the general account do not exceed 10% of the total reserves and liabilities of the general account (exclusive of separate account liabilities) plus surplus as set forth in the NAIC Annual Statement filed with such Purchaser’s state of domicile, and the purchase is not part of an agreement, arrangement or understanding designed to benefit a “party in interest” (as that term is defined in ERISA section 3(14)) within the meaning of PTE 95-60; or

(b)          the Source is a separate account that is maintained solely in connection with such Purchaser’s fixed contractual obligations under which the amounts payable, or credited, to any employee benefit plan (or its related trust) that has any interest in such separate account (or to any participant or beneficiary of such plan (including any annuitant)) are not affected in any manner by the investment performance of the separate account and the Purchaser’s fixed contractual obligations otherwise meet the requirements for a “Guaranteed Benefit Policy” as defined in ERISA section 401(b)(2); or

(c)          the Source is either (i) an insurance company pooled separate account, within the meaning of PTE 90-1 or (ii) a bank collective investment fund, within the meaning of the PTE 91-38, and no employee benefit plan or group of plans maintained by the same employer or employee organization beneficially owns more than 10% of all assets allocated to such pooled separate account or collective investment fund , and the insurance company or bank agrees to maintain records and make such records available as required under XXX 00-0 Xxxx XXX(x) and (c) or PTE 91-38 Part III(b) and (c); or

(d)          the Source constitutes assets of an “investment fund” (within the meaning of Part VI of PTE 84-14 (the “QPAM Exemption”)) managed by a “qualified professional asset manager” or “QPAM” (within the meaning of Part VI of the QPAM Exemption), no employee benefit plan’s assets that are managed by the QPAM in such investment fund, when combined with the assets of all other employee benefit plans established or maintained by the same employer or by an affiliate (within the meaning of Part VI(c)(1) of the QPAM Exemption) of such employer or by the same employee organization and managed by such QPAM, represent more than 20% of the total client assets managed by such QPAM, the conditions of Part I(c) and (g) of the QPAM Exemption are satisfied, neither the QPAM nor a person controlling or controlled by the QPAM maintains an ownership interest in the Company that would cause the QPAM and the Company to be “related” within the meaning of Part VI(h) of the QPAM Exemption and (i) the identity of such QPAM and (ii) the names of any employee benefit plans whose assets in the investment fund, when combined with the assets of all other employee benefit plans established or maintained by the same employer or by an affiliate (within the meaning of Part VI(c)(1) of the QPAM Exemption) of such employer or by the same employee organization, represent 10% or more of the assets of such investment fund, have been disclosed to the Company in writing pursuant to this clause (d); or

-4-

(e)          the Source constitutes assets of a “plan(s)” (within the meaning of Part IV(h) of PTE 96-23 (the “INHAM Exemption”)) managed by an “in-house asset manager” or “INHAM” (within the meaning of Part IV(a) of the INHAM Exemption), the conditions of Part I(a), (g) and (h) of the INHAM Exemption are satisfied, neither the INHAM nor a person controlling or controlled by the INHAM (applying the definition of “control” in Part IV(d)(3) of the INHAM Exemption) owns a 10% or more interest in the Company and (i) the identity of such INHAM and (ii) the name(s) of the employee benefit plan(s) whose assets constitute the Source have been disclosed to the Company in writing pursuant to this clause (e); or

(f)          the Source is a governmental plan and there is no applicable law that prohibits or limits that plan’s purchase of Notes pursuant to this Supplement; or

(g)          the Source is one or more employee benefit plans, or a separate account or trust fund comprised of one or more employee benefit plans, each of which has been identified to the Company in writing pursuant to this clause (g); or

(h)          the Source does not include assets of any employee benefit plan or Individual Retirement Account, other than a plan exempt from the coverage of ERISA.

As used in this paragraph 6, the terms “employee benefit plan,” “governmental plan,” and “separate account” shall have the respective meanings assigned to such terms in section 3 of ERISA.

7.          Maturity of the Series 2015A Notes; Interest. There are no scheduled prepayments on any of the Series 2015A Notes. The entire unpaid principal amount of the Tranche A Notes shall become due and payable on August 20, 2022. The entire unpaid principal amount of the Tranche B Notes shall become due and payable on August 20, 2025. The Series 2015A Notes shall bear interest at the rates set forth therein.

8.          Definition of Make-Whole Amount. The term “Make-Whole Amount” means, with respect to any Series 2015A Note, an amount equal to the excess, if any, of the Discounted Value of the Remaining Scheduled Payments with respect to the Called Principal of such Series 2015A Note over the amount of such Called Principal, provided that the Make-Whole Amount may in no event be less than zero. For the purposes of determining the Make-Whole Amount, the following terms have the following meanings:

“Called Principal” means, with respect to any Series 2015A Note, the principal of such Series 2015A Note that is to be prepaid pursuant to Section 8.2 of the Note Purchase Agreement or has become or is declared to be immediately due and payable pursuant to Section 12.1 of the Note Purchase Agreement, as the context requires.

“Discounted Value” means, with respect to the Called Principal of any Series 2015A Note, the amount obtained by discounting all Remaining Scheduled Payments with respect to such Called Principal from their respective scheduled due dates to the Settlement Date with respect to such Called Principal, in accordance with accepted financial practice and at a discount factor (applied on the same periodic basis as that on which interest on the Series 2015A Notes is payable) equal to the Reinvestment Yield with respect to such Called Principal.

-5-

“Reinvestment Yield” means, with respect to the Called Principal of any Series 2015A Note, 0.50% over the yield to maturity implied by the yield(s) reported as of 10:00 a.m. (New York City time) on the second Business Day preceding the Settlement Date with respect to such Called Principal, on the display designated as “Page PX1” (or such other display as may replace Page PX1) on Bloomberg Financial Markets for the most recently issued actively traded on-the-run U.S. Treasury securities (“Reported”) having a maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date. If there are no such U.S. Treasury securities Reported having a maturity equal to such Remaining Average Life, then such implied yield to maturity will be determined by (a) converting U.S. Treasury xxxx quotations to bond equivalent yields in accordance with accepted financial practice and (b) interpolating linearly between the yields Reported for the applicable most recently issued actively traded on-the-run U.S. Treasury securities with the maturities (1) closest to and greater than such Remaining Average Life and (2) closest to and less than such Remaining Average Life. The Reinvestment Yield shall be rounded to the number of decimal places as appears in the interest rate of the applicable Note.

If such yields are not Reported or the yields Reported as of such time are not ascertainable (including by way of interpolation), then “Reinvestment Yield” means, with respect to the Called Principal of any Series 2015A Note, 0.50% over the yield to maturity implied by the U.S. Treasury constant maturity yields reported, for the latest day for which such yields have been so reported as of the second Business Day preceding the Settlement Date with respect to such Called Principal, in Federal Reserve Statistical Release H.15 (or any comparable successor publication) for the U.S. Treasury constant maturity having a term equal to the Remaining Average Life of such Called Principal as of such Settlement Date. If there is no such U.S. Treasury constant maturity having a term equal to such Remaining Average Life, such implied yield to maturity will be determined by interpolating linearly between (1) the U.S. Treasury constant maturity so reported with the term closest to and greater than such Remaining Average Life and (2) the U.S. Treasury constant maturity so reported with the term closest to and less than such Remaining Average Life. The Reinvestment Yield shall be rounded to the number of decimal places as appears in the interest rate of the applicable Series 2015A Note.

“Remaining Average Life” means, with respect to any Called Principal, the number of years obtained by dividing (i) such Called Principal into (ii) the sum of the products obtained by multiplying (a) the principal component of each Remaining Scheduled Payment with respect to such Called Principal by (b) the number of years, computed on the basis of a 360-day year composed of twelve 30-day months and calculated to two decimal places, that will elapse between the Settlement Date with respect to such Called Principal and the scheduled due date of such Remaining Scheduled Payment.

“Remaining Scheduled Payments” means, with respect to the Called Principal of any Series 2015A Note, all payments of such Called Principal and interest thereon 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 Series 2015A 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 8.4 or Section 12.1.

-6-

“Settlement Date” means, with respect to the Called Principal of any Series 2015A Note, the date on which such Called Principal is to be prepaid pursuant to Section 8.2 or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires.

9.          Definition of “Default Rate”. The term “Default Rate” means, with respect to the Series 2015A Notes, that rate of interest that is the greater of (i) 2% per annum above the rate of interest stated in clause (a) of the first paragraph of the Series 2015A Notes and (ii) 2% over the rate of interest publicly announced by JPMorgan Chase Bank, N.A. in New York, New York as its “base” or “prime” rate.

10.         Applicability of Note Purchase Agreement. Except as otherwise expressly provided herein (and expressly permitted by the Note Purchase Agreement), all of the provisions of the Note Purchase Agreement are incorporated by reference herein, shall apply to the Series 2015A Notes as if expressly set forth in this Supplement and all references to “Notes” shall include the Series 2015A Notes. Without limiting the foregoing, each Obligor agrees to pay all costs and expenses incurred in connection with the initial filing of this Supplement and all related documents and financial information with the SVO provided that such costs and expenses with respect to the Series 2015A Notes shall not exceed $4,000. Capitalized terms used herein without definition have the respective meanings ascribed to them in the Note Purchase Agreement.

Prior to the occurrence of the Closing, (a) the term “holder” as used in Sections 7, 10.15 and 17 of the Note Purchase Agreement shall be deemed to include the Purchasers of the Series 2015A Notes to be issued at such Closing, and (b) for purposes of the term “Required Holders” as used in the Note Purchase Agreement, the Series 2015A Notes scheduled to be issued at such Closing shall be deemed to be outstanding.

11.         Governing Law.           This Supplement shall be construed and enforced in accordance with, and the rights of the parties shall be governed by, New York law, excluding choice-of-law principles of the law of such State that would permit the application of the laws of a jurisdiction other than such State.

12.         Agreement to be Bound. The Obligors and each Purchaser, to the extent that it was not a party to the Note Purchase Agreement prior to the date of this Supplement, agree to be bound by and comply with the terms and provisions of the Note Purchase Agreement as fully and completely as if such Purchaser were an original signatory to the Note Purchase Agreement.

[The remainder of this page is intentionally left blank.]

The execution hereof shall constitute a contract between the Obligors and the Purchaser(s) for the uses and purposes hereinabove set forth, and this Supplement may be executed in any number of counterparts, each executed counterpart constituting an original but all together only one agreement.

Supplemental Representations

Each Obligor represents and warrants to each Purchaser that except as hereinafter set forth in this Exhibit A, each of the representations and warranties set forth in Section 5 of the Note Purchase Agreement is true and correct in all material respects as of the date hereof with respect to the Series 2015A Notes with the same force and effect as if each reference to “Series 2008A Notes” set forth therein was modified to refer to the “Series 2015A Notes” and each reference to “this Agreement” therein was modified to refer to the Note Purchase Agreement as supplemented by the First Supplement, the Second Supplement and the Third Supplement. Capitalized terms used herein without definition herein or in the First Supplement or the Second Supplement have the respective meanings ascribed to them in the Note Purchase Agreement. The Section references hereinafter set forth correspond to the similar sections of the Note Purchase Agreement, where similar sections exist, which are supplemented hereby:

Section 5.1. Organization; Power and Authority. Each Obligor is a corporation, partnership, limited liability company or similar business entity duly organized, validly existing and in good standing under the laws of its jurisdiction of organization, and is duly qualified as a foreign corporation and is in good standing in each jurisdiction in which such qualification is required by law, other than those jurisdictions as to which the failure to be so qualified or in good standing would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. Each Obligor has the corporate (or equivalent company or partnership) power and authority to own or hold under lease the properties it purports to own or hold under lease, to transact the business it transacts and proposes to transact, to execute and deliver this Supplement and the Series 2015A Notes and to perform the provisions hereof and thereof.

Section 5.3. Disclosure. The Private Placement Memorandum dated May 2015, including the filings made by the Company with the U.S. Securities and Exchange Commission that are incorporated therein by reference (collectively, the “Memorandum”) fairly describes, in all material respects, the general nature of the business and principal properties of the Company and its Subsidiaries. The Note Purchase Agreement (as amended and supplemented to date), the Memorandum and the documents, certificates or other writings delivered to the Purchasers by or on behalf of the Obligors in connection with the transactions contemplated hereby, and the financial statements described on Schedule 5.5 to the Third Supplement (the Note Purchase Agreement, the Memorandum and such documents, certificates or other writings and such financial statements delivered to each Purchaser being referred to, collectively, as the “Disclosure Documents”), taken as a whole, do not contain any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein not misleading in light of the circumstances under which they were made. Except as disclosed in the Disclosure Documents, since December 31, 2014, there has been no change in the financial condition, operations, business, properties or prospects of the Company or any of its Subsidiaries except changes that individually or in the aggregate would not reasonably be expected to have a Material Adverse Effect. There is no fact known to the Obligors that would reasonably be expected to have a Material Adverse Effect that has not been set forth herein or in the Disclosure Documents.

Exhibit A

(to Third Supplement to Master Note Purchase Agreement)

Section 5.4. Organization and Ownership of Shares of Subsidiaries; Affiliates. (a) Schedule 5.4 to the Third Supplement contains (except as noted therein) complete and correct lists of: (i) the Company’s Subsidiaries, showing, as to each Subsidiary, the correct name thereof and the jurisdiction of its organization, (ii) the Company’s Affiliates, other than Subsidiaries, and (iii) the Company’s directors and senior officers. Each of the Obligors (other than the Company) are wholly-owned by the Company, either directly or indirectly through one or more wholly-owned Subsidiaries.

(b) All of the outstanding shares of capital stock or similar equity interests of each Subsidiary shown in Schedule 5.4 to the Third Supplement as being owned by the Obligors have been validly issued, are fully paid and nonassessable and are owned by the Company or another Obligor free and clear of any Lien (except as otherwise disclosed in Schedule 5.4 to the Third Supplement).

(c) No Subsidiary is a party to, or otherwise subject to any legal, regulatory, contractual or other restriction (other than the Note Purchase Agreement, the Bank Credit Agreement, the agreements listed on Schedule 5.4 to the Third Supplement and customary limitations imposed by corporate law or similar statutes) restricting the ability of such Subsidiary to pay dividends out of profits or make any other similar distributions of profits to the Obligors or any of its Subsidiaries that owns outstanding shares of capital stock or similar equity interests of such Subsidiary.

Section 5.5. Financial Statements; Material Liabilities. The Company has delivered to each Purchaser copies of the financial statements of the Company and its Subsidiaries described on Schedule 5.5 to the Third Supplement. All of said financial statements (including in each case the related schedules and notes) fairly present in all material respects the consolidated financial position of the Company and its Subsidiaries as of the respective dates specified therein and the consolidated results of their operations and cash flows for the respective periods so specified and have been prepared in accordance with GAAP consistently applied throughout the periods involved except as set forth in the notes thereto (subject, in the case of any interim financial statements, to normal year-end adjustments). The Company and its Subsidiaries do not have any Material liabilities that are not disclosed on such financial statements or otherwise disclosed in the Disclosure Documents.

Section 5.9. Taxes. The Obligors have filed all tax returns that are required to have been filed in any jurisdiction (unless, and only to the extent that, such Obligor has set aside on its books provisions reasonably adequate for the payment of all unpaid and unreported taxes), and have paid all taxes shown to be due and payable on such returns and all other taxes and assessments levied upon them or their properties, assets, income or franchises, to the extent such taxes and assessments have become due and payable and before they have become delinquent, except for any taxes and assessments (i) the amount of which is not individually or in the aggregate Material or (ii) the amount, applicability or validity of which is currently being contested in good faith by appropriate proceedings and with respect to which any Obligor or a Subsidiary, as the case may be, has established adequate reserves in accordance with GAAP. None of the Obligors knows of any basis for any other tax or assessment that would reasonably be expected to have a Material Adverse Effect. The charges, accruals and reserves on the books of the Company and its Subsidiaries in respect of Federal, state or other taxes for all fiscal periods are adequate. The Federal income tax liabilities of Obligors have been finally determined (whether by reason of completed audits or the statute of limitations having run) for all fiscal years up to and including the fiscal year ended December 31, 2010.

A-2

Section 5.13. Private Offering by the Obligors. None of the Obligors nor anyone acting on its behalf has offered the Series 2015A Notes, or any securities required to be integrated under any federal or state securities laws, for sale to, or solicited any offer to buy any of the same from, or otherwise approached or negotiated in respect thereof with, any person other than the Purchasers and not more than 60 other Institutional Investors, each of which has been offered the Series 2015A Notes at a private sale for investment. None of the Obligors nor anyone acting on its behalf has taken, or will take, any action that would subject the issuance or sale of the Series 2015A Notes to the registration requirements of Section 5 of the Securities Act or to the registration requirements of any securities or blue sky laws of any applicable jurisdiction.

Section 5.14. Use of Proceeds; Margin Regulations. The Obligors will apply the proceeds of the sale of the Series 2015A Notes to refinance existing Indebtedness and for general corporate purposes of the Obligors, which may include acquisitions. No part of the proceeds from the sale of the Series 2015A Notes pursuant to the Third Supplement will be used, directly or indirectly, for the purpose of buying or carrying any margin stock within the meaning of Regulation U of the Board of Governors of the Federal Reserve System (12 CFR 221), or for the purpose of buying or carrying or trading in any securities under such circumstances as to involve the Obligors in a violation of Regulation X of said Board (12 CFR 224) or to involve any broker or dealer in a violation of Regulation T of said Board (12 CFR 220). Margin stock does not constitute more than 5% of the value of the consolidated assets of the Company and its Subsidiaries and the Company does not have any present intention that margin stock will constitute more than 5% of the value of such assets. As used in this Section, the terms “margin stock” and “purpose of buying or carrying” shall have the meanings assigned to them in said Regulation U.

Section 5.15. Existing Indebtedness. Except as described therein, Schedule 5.15 to the Third Supplement sets forth a complete and correct list of all outstanding Indebtedness of the Company and its Subsidiaries as of May 31, 2015 (including a description of the obligors and obligees, principal amount outstanding and collateral therefor, if any, and Guaranty thereof, if any), since which date there has been no Material change in the amounts, interest rates, sinking funds, installment payments or maturities of the Indebtedness of the Obligors. None of the Obligors is in default, and no waiver of default is currently in effect, in the payment of any principal or interest on any Indebtedness of any Obligor, and no event or condition exists with respect to any Indebtedness of any Obligor that, in each case, (i) has existed for such period of time as would permit (after the giving of appropriate notice, if required) one or more Persons to cause such Indebtedness to become due and payable before its stated maturity or before its regularly scheduled dates of payment and (ii) would reasonably be expected to have a Material Adverse Effect.

(b) Except as disclosed in Schedule 5.15 to the Third Supplement, none of the Obligors has agreed or consented to cause or permit in the future (upon the happening of a contingency or otherwise) any of its property, whether now owned or hereafter acquired, to be subject to a Lien not permitted by Section 10.2.

A-3

(c) None of the Obligors are a party to, or otherwise subject to any provision contained in, any instrument evidencing Indebtedness of any Obligor, any agreement relating thereto or any other agreement (including, but not limited to, its charter or other organizational document) which limits the amount of, or otherwise imposes restrictions on the incurring of, Indebtedness of the Company, except the Bank Credit Agreement and as otherwise specifically indicated in Schedule 5.15 to the Third Supplement.
