 Subject to the limitations set forth in the preamble to ARTICLE 3 of this Supplemental Indenture, Article Fourteen of the Original Indenture is hereby amended by adding the following Sections 14.4 and 14.5 thereto:

 Section 14.4 Guarantors May Consolidate, etc., on Certain Terms. 
 Except as otherwise provided in Section 14.5 of this Indenture, no Guarantor may sell or otherwise dispose of all or substantially
all of its assets to, or consolidate with or merge with or into (regardless of whether such Guarantor is the surviving Person) another Person, other than the Company or another Guarantor, unless: 
 (a) immediately after giving effect to such transaction, no Default or Event of Default exists; and 
 (b) either: 
 (i) subject to Section 14.5 hereof, if it is not such Guarantor, the Person acquiring the property in any such sale or disposition or the Person formed by or surviving any such consolidation or merger assumes all the obligations of
that Guarantor under this Indenture (including its Subsidiary Guarantee), on the terms set forth herein, pursuant to a supplemental indenture in form and substance reasonably satisfactory to the Trustee, in which case the Subsidiary Guarantee of
such Guarantor will be released as contemplated by Section 14.5 of this Indenture; or 
 (ii) the Net Proceeds of such
sale or other disposition are applied in accordance with the applicable provisions of this Indenture, including without limitation Section 10.12. 
 In case of any such consolidation, merger, sale or conveyance and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee,
of the Subsidiary Guarantee of such Guarantor and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the Guarantor, such successor Person will succeed to and be substituted for the Guarantor
with the same effect as if it had been named herein as a Guarantor. Such successor Person thereupon may cause to be signed any or all of the Subsidiary Guarantee notations to be endorsed upon all of the Notes issuable hereunder which theretofore
shall not have been signed by the Company and delivered to the Trustee. All the Subsidiary Guarantees so issued will in all respects have the same legal rank and benefit under this Indenture as the Subsidiary Guarantees theretofore and thereafter
issued in accordance with the terms of this Indenture as though all of such Subsidiary Guarantees had been issued at the date of the execution hereof. 
 Except as set forth in Articles Eight and Ten of this Indenture, and notwithstanding clauses (i) and (ii) above, nothing contained in this Indenture or in any of the Notes will prevent any consolidation or
merger of a Guarantor with or into the Company or another Guarantor, or will prevent any sale or conveyance of the property of a Guarantor as an entirety or substantially as an entirety to the Company or another Guarantor. 
  

 37 
 First Supplemental Indenture 

 Section 14.5 Releases. 
 (a) In the event of any sale or other disposition of all or substantially all of the assets of any Guarantor, by way of merger,
consolidation or otherwise, or a sale or other disposition of all of the Capital Stock of any Guarantor, in each case to a Person that is not (either before or after giving effect to such transactions) the Company or a Restricted Subsidiary of the
Company, then such Guarantor (in the event of a sale or other disposition, by way of merger, consolidation or otherwise, of all of the Capital Stock of such Guarantor) or the corporation acquiring the property (in the event of a sale or other
disposition of all or substantially all of the assets of such Guarantor) will be released and relieved of any obligations under its Subsidiary Guarantee, provided that the Net Proceeds of such sale or other disposition are applied in
accordance with the applicable provisions of this Indenture, including without limitation Section 10.12. Upon delivery by the Company to the Trustee of an Officers’ Certificate and an Opinion of Counsel to the effect that such sale or
other disposition was made by the Company in accordance with the provisions of this Indenture, including without limitation Section 10.12, the Trustee will execute any documents reasonably required in order to evidence the release of any
Guarantor from its obligations under its Subsidiary Guarantee. 
 (b) In addition, each Guarantor will be released and
relieved of any obligations under its Subsidiary Guarantee: 
 (i) upon designation of such Guarantor as an Unrestricted
Subsidiary in accordance with the terms of this Indenture; 
 (ii) upon Legal Defeasance in accordance with Article Thirteen
of this Indenture or satisfaction and discharge of this Indenture in accordance with Article Four of this Indenture; 
 (iii)
upon the liquidation or dissolution of such Guarantor, provided that no Default or Event of Default shall have occurred and is continuing; or 
 (iv) at such time as such Guarantor does not have outstanding any Guarantee of any Indebtedness (other than the Notes) of the Company or any Guarantor in excess of $10.0 million in aggregate principal amount.

 (c) Any Guarantor not released from its obligations under its Subsidiary Guarantee as provided in this Section 14.5
will remain liable for the full amount of principal of and interest and premium, if any, on the Notes and for the other obligations of any Guarantor under this Indenture as provided in this Article Fourteen.

and 
 (ix) that Holders whose Notes were purchased only in part shall be issued new Notes equal in principal amount to the
unpurchased portion of the Notes surrendered (or transferred by book entry transfer).

Paying Agent, as the case may be, shall promptly (but in any case not later than three days after the Purchase Date) mail or deliver to each tendering Holder an amount equal to the purchase price of Notes tendered by such Holder, as the case may be,
and accepted by the Company for purchase, and the Company shall promptly issue a new Note. The Trustee, upon written request from the Company shall authenticate and mail or deliver such new Note to such Holder, in a principal amount equal to any
unpurchased portion of the Note surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Company to the respective Holder thereof. The Company shall publicly announce the results of the Repurchase Offer on the Purchase

 (i) the payment of any dividend or the consummation of any irrevocable redemption within 60 days after the date of declaration of the dividend or giving of the redemption notice, as the case may be, if at the date of declaration or notice,
the dividend or redemption payment would have complied with the provisions of this Indenture;

if the same had occurred at the beginning of the Company’s most recently ended four full fiscal quarters for which internal financial statements are
available, the Company’s Leverage Ratio would not have exceeded 2.5 to 1; 
 (xii) the purchase or redemption of any
Acquired Subordinated Indebtedness of the Company or any of its Restricted Subsidiaries, by application of (A) cash provided from operations in the ordinary course of business or (B) proceeds from borrowings under the revolving portion of

 (B) in the case of an Asset Sale, the Company has complied with and fully satisfied its obligations under Section 10.12; or

 (xiv) other Restricted Payments in an amount not to exceed $50.0 million. 
 (c) The amount of all Restricted Payments (other than cash) shall be the Fair Market Value on the date of such Restricted Payment of the
asset(s) or securities proposed to be paid, transferred or issued by the Company or such Restricted Subsidiary, as the case may be, pursuant to such Restricted Payment. 
 (d) The Fair Market Value of any cash Restricted Payment shall be its face amount, and the Fair Market Value of any non-cash Restricted
Payment exceeding $15.0 million shall be determined conclusively by two Officers of the Company acting in good faith whose conclusions with respect thereto shall be set forth in an Officers’ Certificate delivered to the Trustee,
provided, however, that if the Fair Market Value of any non-cash Restricted Payment exceeds $40.0 million, such Fair Market Value shall be determined conclusively by the Board of Directors of the Company and set forth in a Board
Resolution, and a certified copy of such Board Resolution shall be delivered to the Trustee. For purposes of determining compliance with this covenant, in the event that a Restricted Payment meets the criteria of more than one of the exceptions
described in clauses (i) through (xiv) of Section 10.9(b) or is entitled to be made pursuant to Section 10.9(a), the Company shall, in its sole discretion, classify such Restricted Payment, or later classify, reclassify or

 SECTION 4.04. Dividend and Other Payment Restrictions Affecting Restricted
Subsidiaries. 
 Subject to the limitations set forth in the preamble to ARTICLE 4 of this Supplemental Indenture, Article Ten

 Section 10.10 Dividend and
Other Payment Restrictions Affecting Restricted Subsidiaries. 
 (a) The Company will not, and will not permit any of its
Restricted Subsidiaries to, directly or indirectly, create or permit to exist or become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary to: 
 (i) pay dividends or make any other distributions on its Capital Stock to the Company or any of its Restricted Subsidiaries, or with
respect to any other interest or participation in, or measured by, its profits, or pay any indebtedness owed to the Company or any of its Restricted Subsidiaries; 
 (ii) make loans or advances to the Company or any of its Restricted Subsidiaries; or 
 (iii) sell, lease or transfer any of its properties or assets to the Company or any of its Restricted Subsidiaries.

reason of: 
 (i) agreements governing Existing Indebtedness and Credit Facilities as in effect on the Issue Date and any
amendments, restatements, modifications, renewals, supplements, increases, refundings, replacements or refinancings of those agreements; provided that the amendments, restatements, modifications, renewals, supplements, increases, refundings,
replacements or refinancings are no more restrictive, taken as a whole, with respect to such dividend and other payment restrictions than those contained in those agreements on the Issue Date; 
 (ii) this Indenture, the Notes and the Subsidiary Guarantees; 
 (iii) applicable law, rule, regulation, order, approval, permit or similar restriction; 
 (iv) any instrument governing Indebtedness or Capital Stock of a Person acquired by the Company or any of its Restricted Subsidiaries as
in effect at the time of such acquisition (except to the extent such Indebtedness or Capital Stock was incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction is not applicable to any Person, or the
properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired; provided that, in the case of Indebtedness, such Indebtedness was permitted by the terms of this Indenture to be incurred;

 (v) customary non-assignment provisions in contracts, leases and licenses (including, without limitation, licenses of
intellectual property) entered into in the ordinary course of business; 
 (vi) any agreement for the sale or other

 46 
 First Supplemental Indenture 

 
assets of a Restricted Subsidiary, that restricts distributions by the applicable Restricted Subsidiary pending the sale or other disposition; 
 (vii) Permitted Refinancing Indebtedness; provided that the restrictions contained in the agreements governing such Permitted
Refinancing Indebtedness are not materially more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being refinanced; 
 (viii) Liens permitted to be incurred under the provisions of Section 10.14 that limit the right of the debtor to dispose of the
assets subject to such Liens; 
 (ix) the issuance of preferred stock by a Restricted Subsidiary or the payment of dividends
thereon in accordance with the terms thereof; provided that issuance of such preferred stock is permitted pursuant to Section 10.11 and the terms of such preferred stock do not expressly restrict the ability of a Restricted Subsidiary to
pay dividends or make any other distributions on its Capital Stock (other than requirements to pay dividends or liquidation preferences on such preferred stock prior to paying any dividends or making any other distributions on such other Capital
Stock); 
 (x) other Indebtedness of the Company or any of its Restricted Subsidiaries permitted to be incurred pursuant to an
agreement entered into subsequent to the Issue Date in accordance with Section 10.11; provided that the provisions relating to such encumbrance or restriction contained in such Indebtedness are not materially less favorable to the
Company and its Restricted Subsidiaries taken as a whole, as determined by the Company in good faith, than the provisions contained in the Credit Facilities and in this Indenture as in effect on the Issue Date; 
 (xi) customary provisions restricting subletting or assignment of any lease governing a leasehold interest; 
 (xii) Hedging Obligations permitted from time to time under this Indenture;

interests therein; 
 (B) provisions limiting the disposition or distribution of assets or property in, or transfer of
Capital Stock of, joint venture agreements, asset sale agreements, sale-leaseback agreements, stock sale agreements and other similar agreements entered into (1) in the ordinary course of business, consistent with past practice or (2) with
the approval of the Company’s Board of Directors, which limitations are applicable only to the assets, property or Capital Stock that are the subject of such agreements; and 
 (C) Capital Lease Obligations, security agreements, mortgages, purchase money agreements or similar instruments to the extent such

  

 47 
 First Supplemental Indenture 

 
encumbrance or restriction restricts the transfer of the property (including Capital Stock) subject to such Capital Lease Obligations, security agreements,
mortgages, purchase money agreements or similar instruments. 
 SECTION 4.05. Incurrence of Indebtedness and Issuance of
Preferred Stock. 
 Subject to the limitations set forth in the preamble to ARTICLE 4 of this Supplemental Indenture, Article
Ten of the Original Indenture is hereby further amended by adding the following Section 10.11 thereto: 
 Section 10.11
Incurrence of Indebtedness and Issuance of Preferred Stock. 
 (a) The Company will not, and will not permit any of its
Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur;” with “incurrence”
having a correlative meaning) any Indebtedness (including Acquired Debt), and the Company will not issue any Disqualified Stock and will not permit any of its Restricted Subsidiaries to issue any shares of preferred stock; provided,
however, that the Company may incur Indebtedness (including Acquired Debt) and issue Disqualified Stock, and Restricted Subsidiaries may incur Indebtedness (including Acquired Debt) and issue preferred stock, if the Fixed Charge Coverage
Ratio for the Company’s most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date on which such additional Indebtedness is incurred or such Disqualified Stock or preferred
stock is issued, as the case may be, would have been at least 2.25 to 1.0, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness had been incurred or the Disqualified
Stock or preferred stock had been issued, as the case may be, at the beginning of such four-quarter period. 
 (b)
Notwithstanding the foregoing, Section 10.11(a) will not prohibit the incurrence of any of the following (the items of Indebtedness described below in this Section 10.11(b) being referred to collectively as “Permitted Debt”):

 (i) the incurrence by the Company and any Restricted Subsidiary of Indebtedness and letters of credit under Credit
Facilities in an aggregate principal amount at any one time outstanding under this clause (i) (with letters of credit being deemed to have a principal amount equal to the maximum potential liability of the Company and its Restricted
Subsidiaries thereunder) not to exceed the greater of (x) $1.1 billion and (y) 20% of Adjusted Consolidated Net Tangible Assets, determined as of the date of the incurrence of such Indebtedness after giving pro forma effect to such
incurrence and the application of the proceeds therefrom; 
 (ii) the incurrence by the Company and its Restricted
Subsidiaries of the Existing Indebtedness; 
 (iii) the incurrence by the Company and the Guarantors of Indebtedness
represented by the Notes and the related Subsidiary Guarantees, in each case to be issued on the Issue Date; 
 (iv) the
incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness represented by Capital Lease Obligations, mortgage financings or purchase money obligations, in each case, incurred for the purpose of financing all or any part of the
purchase price or cost of design, construction, installation or improvement of property, plant or equipment used in the business of the Company or any of its Restricted 

  

 48 
 First Supplemental Indenture 

 
Subsidiaries, in an aggregate principal amount, including all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or
discharge any Indebtedness incurred pursuant to this clause (iv), not to exceed $50.0 million at any time outstanding; 
 (v)
the incurrence by the Company or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to refund, refinance, replace, defease or discharge Indebtedness (other than
intercompany Indebtedness) or Disqualified Stock of the Company, or Indebtedness (other than intercompany Indebtedness) or preferred stock of a Restricted Subsidiary, in each case that was permitted by this Indenture to be incurred or issued under
Section 10.11(a) or clauses (ii), (iii), (iv), (v) or (x) of this Section 10.11(b); 
 (vi) the incurrence
by the Company or any of its Restricted Subsidiaries of intercompany Indebtedness between or among the Company and any of its Restricted Subsidiaries; provided, however, that (A) any subsequent issuance or transfer of Equity
Interests that results in any such Indebtedness being held by a Person other than the Company or a Restricted Subsidiary and (B) any sale or other transfer of any such Indebtedness to a Person that is not either the Company or a Restricted
Subsidiary will be deemed, in each case, to constitute an incurrence of such Indebtedness by the Company or such Restricted Subsidiary, as the case may be, that was not permitted by this clause (vi); 
 (vii) the issuance by any of the Company’s Restricted Subsidiaries to the Company or to any of its Restricted Subsidiaries of shares
of preferred stock; provided, however, that: 
 (A) any subsequent issuance or transfer of Equity Interests
that results in any such preferred stock being held by a Person other than the Company or a Restricted Subsidiary; and 
 (B)
any sale or other transfer of any such preferred stock to a Person that is not either the Company or a Restricted Subsidiary, 
 will be
deemed, in each case, to constitute an issuance of such preferred stock by such Restricted Subsidiary that was not permitted by this clause (vii); 
 (viii) the incurrence of obligations of the Company or a Restricted Subsidiary pursuant to Interest Rate and Currency Hedges, in each case entered into in the ordinary course of business for the purpose of limiting
risks that arise in the ordinary course of business of the Company and its Restricted Subsidiaries; 
 (ix) the guarantee by
the Company or any of the Guarantors of Indebtedness of the Company or a Restricted Subsidiary that was permitted to be incurred by another provision of this covenant; provided that if the Indebtedness being guaranteed is subordinated to or
pari passu with the Notes, then the guarantee shall be subordinated or pari passu, as applicable, to the same extent as the Indebtedness guaranteed; 
 (x) Permitted Acquisition Indebtedness; 
 (xi) the incurrence by the Company or any Restricted Subsidiary of Indebtedness arising from the honoring by a bank or other financial institution of a check, 

  

 49 
 First Supplemental Indenture 

 
draft or similar instrument inadvertently drawn against insufficient funds, so long as such Indebtedness is covered within five Business Days; 
 (xii) Indebtedness consisting of the financing of insurance premiums in customary amounts consistent with the operations and business of
the Company and the Restricted Subsidiaries; 
 (xiii) the incurrence by the Company or any Restricted Subsidiary of
Indebtedness arising from agreements of the Company or any of its Restricted Subsidiaries providing for indemnification, adjustment of purchase price or similar obligations, in each case, incurred or assumed in connection with the disposition of any
business, assets or Capital Stock of a Subsidiary, provided that the maximum aggregate liability in respect of all such Indebtedness shall at no time exceed the gross proceeds actually received by the Company and its Restricted Subsidiaries
in connection with such disposition; 
 (xiv) the incurrence by the Company or any Restricted Subsidiary of Indebtedness
arising from Guarantees of Indebtedness of joint ventures at any time outstanding not to exceed the greater of $50.0 million and 1.0% of Adjusted Consolidated Net Tangible Assets determined as of the date of incurrence of such Indebtedness after
giving pro forma effect to such incurrence and the application of proceeds thereof; and 
 (xv) the incurrence by the Company
or any of its Restricted Subsidiaries of Indebtedness in an aggregate principal amount (or accreted value, as applicable) that, when taken together with all other Indebtedness of the Company outstanding on the date of such incurrence (other than
Indebtedness permitted by clauses (i) through (xiv) above or Section 10.11(a)) does not exceed the greater of (x) 2.5% of Adjusted Consolidated Net Tangible Assets determined as of the date of incurrence of such Indebtedness and
(y) $125.0 million. 
 (c) For purposes of determining compliance with this Section 10.11, in the event that an item
of proposed Indebtedness meets the criteria of more than one of the categories of Permitted Debt described in clauses (i) through (xv) of Section 10.11(b), or is entitled to be incurred pursuant to Section 10.11(a), the Company
will be permitted to divide and classify such item of Indebtedness on the date of its incurrence, or later divide and reclassify all or a portion of such item of Indebtedness, in any manner that complies with this Section 10.11. The accrual of
interest, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, the reclassification of preferred stock as Indebtedness due to a change in
accounting principles, and the payment of dividends on Disqualified Stock in the form of additional shares of the same class of Disqualified Stock will be deemed not to be an incurrence of Indebtedness or an issuance of Disqualified Stock for
purposes of this covenant; provided, in each such case, that the amount of any such accrual, accretion or payment is included in Fixed Charges of the Company as accrued. 
 (d) For purposes of determining compliance with any U.S. dollar-denominated restriction on the incurrence of Indebtedness and issuance of
preferred stock, the U.S. dollar-equivalent principal amount of Indebtedness denominated in a foreign currency shall be calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was incurred, in the case of term
Indebtedness, or first committed, in the case of revolving credit Indebtedness; provided that if such Indebtedness is incurred to refinance other Indebtedness denominated in a foreign currency, and such refinancing would cause the applicable
U.S. dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar-denominated restriction shall be deemed 

  

 50 
 First Supplemental Indenture 

 
not to have been exceeded so long as the principal amount of such refinancing Indebtedness does not exceed the principal amount of such Indebtedness being
refinanced. Notwithstanding any other provision of this Section 10.11, the maximum amount of Indebtedness that the Company may incur pursuant to this Section 10.11 shall not be deemed to be exceeded solely as a result of fluctuations in
the exchange rate of currencies. The principal amount of any Permitted Refinancing Indebtedness incurred to refinance other Indebtedness, if incurred in a different currency from the Indebtedness being refinanced, shall be calculated based on the
currency exchange rate applicable to the currencies in which such Permitted Refinancing Indebtedness is denominated that is in effect on the date of such refinancing. 
 SECTION 4.06. Asset Sales. 
 Subject to the limitations set forth in the preamble
to ARTICLE 4 of this Supplemental Indenture, Article Ten of the Original Indenture is hereby further amended by adding the following Section 10.12 thereto: 
 Section 10.12 Asset Sales. 
 (a) The Company will not, and will not permit any of
its Restricted Subsidiaries to, consummate an Asset Sale unless: 
 (i) the Company (or the Restricted Subsidiary, as the case
may be) receives consideration at least equal to the Fair Market Value of the assets or Equity Interests issued or sold or otherwise disposed of; and 
 (ii) either (x) at least 75% of the consideration received in the Asset Sale by the Company or such Restricted Subsidiary is in the form of cash or Cash Equivalents or (y) the Fair Market Value of all forms
of consideration other than cash and Cash Equivalents received for all Asset Sales since the Issue Date does not exceed in the aggregate 10% of the Adjusted Consolidated Net Tangible Assets of the Company at the time each determination is made. For
purposes of this provision, each of the following will be deemed to be cash: 
 (A) any liabilities, as shown on the
Company’s most recent consolidated balance sheet, of the Company or any Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or any Subsidiary Guarantee) that are assumed by
the transferee of any such assets pursuant to a customary novation agreement that releases the Company or such Restricted Subsidiary from further liability; 
 (B) any securities, notes or other obligations received by the Company or any such Restricted Subsidiary from such transferee that are
converted by the Company or such Restricted Subsidiary into cash within 180 days after the date of the Asset Sale, to the extent of the cash received in that conversion; 
 (C) any stock or assets of the kind referred to in clauses (ii) or (iv) of Section 10.12(b) below; and 
 (D) accounts receivable of a business retained by the Company or any Restricted Subsidiary, as the case may be, following the sale of
such business, provided that such accounts receivable are not (1) past due more than 

  

 51 
 First Supplemental Indenture 

 
90 days and (2) do not have a payment date greater than 120 days from the date of the invoice creating such accounts receivable. 
 (b) Within 360 days after the receipt of any Net Proceeds from an Asset Sale, the Company (or the applicable Restricted Subsidiary, as the
case may be) may apply such Net Proceeds: 
 (i) to repay Senior Debt; 
 (ii) to invest in Additional Assets; 
 (iii) to make capital expenditures in respect of a Related Business of the Company or any of its Restricted Subsidiaries; or 
 (iv) enter into a bona fide binding contract with a Person other than an Affiliate of the Company to apply the Net Proceeds pursuant to
clauses (ii) or (iii) above, provided that such binding contract shall be treated as a permitted application of the Net Proceeds from the date of such contract until the earlier of: 
 (A) the date on which such acquisition or expenditure is consummated, and 
 (B) the 180th day following the expiration of the aforementioned 360-day period. 
 Any Net Proceeds from Asset Sales that are not applied or invested as provided in clauses (i) through (iv) above will constitute “Excess
Proceeds.” 
 (c) On the 361st day (or upon the failure to close the contract referred to in clause (iv) of
Section 10.12(b) above within the 180 day time period thereafter) after the Asset Sale (or, at the Company’s option, any earlier date), if the aggregate amount of Excess Proceeds then exceeds $40.0 million, the Company will make an offer
(the “Asset Sale Offer”) to all Holders of Notes and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in this Indenture with respect to offers to purchase or redeem
with the proceeds of sales of assets, to purchase the maximum principal amount of Notes and such other pari passu Indebtedness that may be purchased out of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of
the principal amount plus accrued and unpaid interest, to the date of purchase, and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company may use those Excess Proceeds for any purpose not
otherwise prohibited by this Indenture. If the aggregate principal amount of Notes and other pari passu Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee will select the Notes to be purchased
on a pro rata basis. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero. 
 (d)
Notwithstanding the foregoing, the sale, conveyance or other disposition of all or substantially all of the assets of the Company, or of the Company and its Restricted Subsidiaries, taken as a whole, will be governed by Sections 8.1 and/or 10.15 of
this Indenture, as applicable, and not by this Section 10.12. 
 (e) The Company will comply with the requirements of
Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with each repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the
provisions of any securities laws or regulations conflict with the Asset Sale provisions of this Indenture, the Company will comply with the applicable securities 

  

 52 
 First Supplemental Indenture 

 
laws and regulations and will not be deemed to have breached its obligations under the Asset Sale provisions of this Indenture by virtue of such compliance.

 SECTION 4.07. Transactions with Affiliates. 
 Subject to the limitations set forth in the preamble to ARTICLE 4 of this Supplemental Indenture, Article Ten of the Original Indenture is hereby further
amended by adding the following Section 10.13 thereto: 
 Section 10.13 Transactions with Affiliates. 
 (a) The Company will not, and will not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or
otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any
Affiliate of the Company (each, an “Affiliate Transaction”), unless: 
 (i) the Affiliate Transaction is on terms
that are no less favorable to the Company or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated Person; and 
 (ii) the Company delivers to the Trustee: 
 (A) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $20.0 million, a Board Resolution of the Company set forth in an Officers’
Certificate certifying that such Affiliate Transaction complies with this Section 10.13 and that such Affiliate Transaction has been approved by a majority of the disinterested members of the Board of Directors of the Company; and 

(B) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess
of $40.0 million, an opinion as to the fairness to the Company or such Subsidiary of such Affiliate Transaction from a financial point of view issued by an accounting, appraisal or investment banking firm of national standing. 
 (b) The following items will not be deemed to be Affiliate Transactions and, therefore, will not be subject to the provisions of the prior
paragraph: 
 (i) any employment, consulting or similar agreement or other compensation, or arrangement, stock option or stock
ownership plan, employee benefit plan, officer or director indemnification agreement, restricted stock agreement, severance agreement or other compensation plan or arrangement entered into by the Company or any of its Restricted Subsidiaries in the
ordinary course of business and payments, awards, grants or issuances of securities pursuant thereto; 
 (ii) transactions

 SECTION
4.08. Limitation on Liens. 
 Subject to the limitations set forth in the preamble to ARTICLE 4 of this Supplemental
Indenture, Article Ten of the Original Indenture is hereby further amended by adding the following Section 10.14 thereto: 
 Section 10.14 Limitation on Liens. 
 The Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create, incur or permit to exist any Lien (other than Permitted Liens) upon any Principal Property or any shares of stock or Indebtedness of any Restricted Subsidiary that owns or leases any Principal
Property (whether such Principal Property, shares of stock or Indebtedness are now owned or hereafter acquired), securing any Subordinated Debt or other Indebtedness, unless: 
 (a) in the case of Liens securing Subordinated Debt of the Company or a Guarantor, the Notes or Subsidiary Guarantee, as applicable, are
secured by a Lien on such Principal 

  

 54 
 First Supplemental Indenture 

 
Property or such shares of stock or Indebtedness on a senior basis to the Subordinated Debt so secured with the same priority as the Notes or such Subsidiary
Guarantee, as applicable, has to such Subordinated Debt until such time as such Subordinated Debt is no longer so secured by a Lien; and 
 (b) in the case of Liens securing other Indebtedness of the Company or a Guarantor, the Notes or Subsidiary Guarantees, as applicable, are secured by a Lien on such Principal Property or such shares of stock or
Indebtedness on an equal and ratable basis with the other Indebtedness so secured until such time as such other Indebtedness is no longer so secured by a Lien. 
 SECTION 4.09. Offer to Repurchase upon a Change of Control. 
 Subject to the
limitations set forth in the preamble to ARTICLE 4 of this Supplemental Indenture, Article Ten of the Original Indenture is hereby further amended by adding the following Section 10.15 thereto: 
 Section 10.15 Offer to Repurchase upon a Change of Control. 
 (a) If a Change of Control Triggering Event occurs, each Holder of Notes will have the right to require the Company to repurchase all or
any part (equal to $1,000 or an integral multiple thereof) of that Holder’s Notes pursuant to an offer (“Change of Control Offer”) on the terms set forth in this Indenture. In the Change of Control Offer, the Company will offer a
payment in cash (the “Change of Control Payment”) equal to 101% of the aggregate principal amount of Notes repurchased plus accrued and unpaid interest on the Notes repurchased to the date of purchase (the “Change of Control Payment
Date”), subject to the rights of Holders of Notes on the relevant record date to receive interest due on the relevant Interest Payment Date. Within 30 days following any Change of Control Triggering Event, the Company will mail a notice to each
Holder of Notes describing the transaction or transactions that constitute the Change of Control Triggering Event and offering to repurchase Notes on the Change of Control Payment Date specified in the notice, which date will be no earlier than 30
days and no later than 60 days from the date such notice is mailed, pursuant to the procedures described in Article Fifteen of this Indenture (including the notice required thereby) and described in such notice. The Company will comply with the
requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control
Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Triggering Event provisions of this Indenture, the Company will comply with the applicable securities laws and regulations
and will not be deemed to have breached its obligations under the Change of Control Triggering Event provisions of this Indenture by virtue of such compliance. 
 (b) On the Change of Control Payment Date, the Company will, to the extent lawful: 
 (i) accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer; 
 (ii) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly
tendered; and 
 (iii) deliver or cause to be delivered to the Trustee the Notes properly accepted together with an
Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Company. 
  

 55 
 First Supplemental Indenture 

 (c) The Paying Agent will promptly mail to each Holder of Notes properly tendered the
Change of Control Payment for such Notes (or, if all the Notes are then in global form, make such payment through the facilities of the Depositary), and the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to
each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided that each such new Note will be in a principal amount of $1,000 or an integral multiple thereof. Any Note so accepted for
payment will cease to accrue interest on and after the Change of Control Payment Date unless the Company defaults in making the Change of Control Payment. 
 (d) The Company will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date. 
 (e) Notwithstanding anything to the contrary in this Section 10.15, the Company will not be required to make a Change of Control
Offer upon a Change of Control Triggering Event if (i) a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control
Offer made by the Company and purchases all Notes properly tendered and not withdrawn under the Change of Control Offer, or (ii) notice of redemption with respect to the Notes has been given pursuant to this Indenture, unless and until there is
a default in payment of the applicable Redemption Price. 
 (f) A Change of Control Offer may be made in advance of a Change
of Control Triggering Event, and conditioned upon the occurrence of such Change of Control Triggering Event, if a definitive agreement is in place for the Change of Control Triggering Event at the time of making the Change of Control Offer. Notes
repurchased by the Company pursuant to a Change of Control Offer will have the status of Notes issued but not Outstanding or will be retired and cancelled, at the Company’s option. Notes purchased by a third party pursuant to clause (e) of
this Section 10.15 will have the status of Notes issued and Outstanding. 
 (g) In the event that Holders of at least 90%
of the aggregate principal amount of the Outstanding Notes accept a Change of Control Offer and the Company purchases all of the Notes held by such Holders, the Company will have the right, upon not less than 30 nor more than 60 days’ prior
notice, given not more than 30 days following the purchase pursuant to the Change of Control Offer described above, to redeem all of the Notes that remain Outstanding following such purchase at a Redemption Price equal to the Change of Control
Payment plus, to the extent not included in the Change of Control Payment, accrued and unpaid interest on the Notes that remain Outstanding, to the date of redemption (subject to the right of Holders on the relevant record date to receive
interest due on the relevant Interest Payment Date). 
 SECTION 4.10. Designation of Restricted and Unrestricted
Subsidiaries. 
 Subject to the limitations set forth in the preamble to ARTICLE 4 of this Supplemental Indenture, Article Ten
of the Original Indenture is hereby further amended by adding the following Section 10.16 thereto: 
 Section 10.16 Designation
of Restricted and Unrestricted Subsidiaries. 
 (a) The Board of Directors of the Company may designate any Restricted
Subsidiary to be an Unrestricted Subsidiary if that designation would not cause a Default. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding Investments owned by the Company
and its Restricted Subsidiaries in the Subsidiary designated as Unrestricted will be deemed to be an Investment made as of the time of the designation and will reduce the amount available for Restricted Payments under Section 10.9 of 

  

 56 
 First Supplemental Indenture 

 
this Indenture or under one or more clauses of the definition of Permitted Investments, as determined by the Company. That designation will only be permitted
if the Investment would be permitted at that time and if the Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. 
 (b) Any designation of a Subsidiary of the Company as an Unrestricted Subsidiary will be evidenced to the Trustee by filing with the Trustee a certified copy of a Board Resolution of the Company giving effect to such
designation and an Officers’ Certificate certifying that such designation complied with the preceding conditions and was permitted by Section 10.9. If, at any time, any Unrestricted Subsidiary would fail to meet the preceding requirements
as an Unrestricted Subsidiary, it will thereafter cease to be an Unrestricted Subsidiary for purposes of this Indenture and any Indebtedness of such Subsidiary will be deemed to be incurred by a Restricted Subsidiary as of such date and, if such
Indebtedness is not permitted to be incurred as of such date under Section 10.11, the Company will be in Default of such covenant. The Board of Directors of the Company may at any time designate any Unrestricted Subsidiary to be a Restricted
Subsidiary; provided that such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of any outstanding Indebtedness of such Unrestricted Subsidiary, and such designation will only be permitted if
(i) such Indebtedness is permitted under Section 10.11, calculated on a pro forma basis as if such designation had occurred at the beginning of the four-quarter reference period; and (ii) no Default or Event of Default would be in
existence following such designation. 
 SECTION 4.11. Future Guarantors. 
 Subject to the limitations set forth in the preamble to ARTICLE 4 of this Supplemental Indenture, Article Ten of the Original Indenture is hereby further
amended by adding the following Section 10.17 thereto: 
 Section 10.17 Future Guarantors. 
 If, after the Issue Date, any Domestic Restricted Subsidiary that is not a Guarantor is or becomes obligated under any Indebtedness
pursuant to a Guarantee of Indebtedness of the Company or any Guarantor (other than the Notes), and the maximum principal amount of Indebtedness of such Domestic Restricted Subsidiary under such Guarantee exceeds $10.0 million, then the Company
shall cause that Domestic Restricted Subsidiary to Guarantee the Notes and become a Guarantor, pursuant to the Subsidiary Guarantee provisions of this Indenture, by executing a supplemental indenture and delivering it to the Trustee within 30 days
after the date on which such Domestic Restricted Subsidiary Guaranteed such Indebtedness of the Company or a Guarantor; provided, however, that the Company shall not be required to cause such Domestic Restricted Subsidiary to so
Guarantee the Notes and become a Guarantor prior to the 180th day after the consummation of any transaction (including without limitation any merger, consolidation or purchase) pursuant to which such Domestic Restricted Subsidiary becomes a
Subsidiary of the Company. 
 SECTION 4.12. Covenant Termination. 
 Subject to the limitations set forth in the preamble to ARTICLE 4 of this Supplemental Indenture, Article Ten of the Original Indenture is hereby further
amended by adding the following Section 10.18 thereto: 
 Section 10.18 Covenant Termination. 
  

 57 
 First Supplemental Indenture 

 Notwithstanding any provision of this Indenture or of the Notes to the contrary, from and
after the occurrence of an Investment Grade Rating Event, the Company and its Restricted Subsidiaries will cease to be subject to Sections 10.9, 10.10, 10.11, 10.12, 10.13, 10.15 and 10.16 and 8.1(a)(iv) of this Indenture and no Default or Event of
Default shall result from any failure to comply with any of the provisions of such Sections.

Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities of this series may be listed, and upon such notice as may be required by such exchange, all as
more fully provided in said Indenture. Interest on the Securities of this series will be computed on the basis of a 360-day year comprised of twelve 30-day months.

and to be issued in one or more series under an Indenture, dated as of March 13, 2007 (the “Original Indenture”), between the Company and Wells Fargo Bank, N.A., as Trustee (herein called the “Trustee”, which term includes
any successor trustee under the Indenture), as amended and supplemented by the First Supplemental Indenture thereto dated as of March 13, 2007 (the “Supplemental Indenture”), by and among the Company, the Trustee and the Guarantors
named therein (such Original Indenture, as so amended and supplemented being herein called the “Indenture”), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement, of the respective rights,
limitations of rights, duties and immunities thereunder of the Company, the Guarantors, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. As provided in the
Indenture, the Securities may be issued in one or more series, which different series may be issued in various aggregate principal amounts, may mature at different times, may bear interest, if any, at different rates, may be subject to different
redemption provisions, if any, may be subject to different sinking, purchase or analogous funds, if any, may be subject to different covenants and Events of Default and may otherwise vary as in the Indenture provided or permitted. This Security is
one of the series designated on the face hereof. 
 This security is the general, unsecured, senior obligation of the Company and is
guaranteed pursuant to a guarantee (the “Subsidiary Guarantee”) by each of the persons named as Guarantors in the Supplemental Indenture (the “Guarantors”). The Subsidiary Guarantee is the general, unsecured, senior obligation of
each Guarantor. 
 Except as described below, and except as provided in Section 10.15(g) of the Indenture, the Securities of this series
are not redeemable until March 15, 2012. On and after March 15, 2012, the Company may redeem all or a part of the Securities of this series, from time to time upon not less than 30 nor more than 60 days’ notice, at the following

record date to receive interest due on the relevant Interest Payment Date), if redeemed during the twelve-month period beginning on March 15 of the years indicated below:

	 2014
	  	101.167	%
	 2015 and thereafter
	  	100.000	%

 The Securities of this series will also be redeemable, in whole or in part, at the Company’s
option at any time or from time to time, prior to March 15, 2012, at the applicable Make-Whole Price (as defined below), in accordance with the provisions of the Indenture. 
 “Make-Whole Price” with respect to any Securities of this series to be redeemed, means an amount equal to the greater of: 
 (1) 100% of the principal amount of such Securities; and 
 (2) the sum of the present values of (a) the Redemption Price of such Securities at March 15, 2012 (as set forth above) and
(b) the remaining scheduled payments of interest from the Redemption Date to March 15, 2012 (not including any portion of such payments of interest accrued as of the Redemption Date) discounted back to the Redemption Date on a semi-annual
basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined below) plus 50 basis points; 
 plus, in
the case of both (1) and (2), accrued and unpaid interest on such Securities to the Redemption Date. Unless the Company defaults in payment of the Make-Whole Price, on and after the applicable Redemption Date, interest will cease to accrue on
the Securities of this series to be redeemed.

financial practice, in pricing new issues of corporate debt securities; provided if such period is less than one year, then the U.S. Treasury security having a maturity of one year shall be used. 
 “Comparable Treasury Price” means, with respect to any Redemption Date, (1) the average of four Reference Treasury Dealer

Treasury Dealer Quotations.

 “Reference Treasury Dealer” means JPMorgan Securities Inc. or Lehman
Brothers Inc. at the Company’s option, and three additional primary U.S. government securities dealers in New York City (each a “Primary Treasury Dealer”) selected by the Company, and its successors (provided,

 “Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any Redemption Date, the average, as
determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m., New York City
time, on the third Business Day preceding such Redemption Date.

 First Supplemental IndentureEmployment Agreement

 Exhibit 10.9 
 EMPLOYMENT AGREEMENT 
 THIS AGREEMENT (the “Agreement”) is entered into on
January 3, 2007, by and between FreightCar America, Inc., a Delaware corporation (the “Company”), and Christian Ragot (the “Executive”). 
 WHEREAS, the Company desires to employ the Executive on January 22, 2007, or such later date mutually agreed by the parties when the Executive is able to commence full-time employment with the Company, but not later
than January 29, 2007 (the “Effective Date”), initially as its Chief Operating Officer and subsequently as its President and Chief Executive Officer; and 
 WHEREAS, the Executive and the Company have reached agreement concerning the terms and conditions of his employment and wish to formalize that agreement; 
 NOW, THEREFORE, in consideration of the mutual terms, covenants and conditions stated in this Agreement, the Executive and the Company agree as follows:

 1. Employment, Position and Duties. From the Effective Date through the close on business on April 30, 2007 (the
“Promotion Time”), the Company shall employ the Executive, and the Executive hereby agrees to serve the Company, as its Chief Operating Officer. Beginning on the Promotion Time, the Company shall employ the Executive, and the Executive
hereby agrees to serve the Company, as its President and Chief Executive Officer, and the Executive shall have such responsibilities, duties and authority as are customarily associated with such office. The Executive also hereby agrees to serve as
an officer of such of the Company’s subsidiaries (if any) as the Board shall reasonably request. 
 2. Board of Directors. As of
the Effective Date, the Company’s Board of Directors (the “Board”) shall elect the Executive to the Board. In accordance with the Company’s bylaws, the Company shall nominate the Executive as a director for shareholder approval
at the 2007 annual meeting and at each annual meeting thereafter during the Term in which his term as a director is due to expire. Prior to his election as a director, the Executive shall submit such resignations as are required from all directors
by Company policy. 
 3. Term. The employment of the Executive by the Company pursuant to this Agreement will commence as of the
Effective Date and will terminate on January 15, 2010; provided, however, that this Agreement, shall remain in effect from year to year thereafter unless, not less than ninety (90) days prior to the then termination of the term of this
Agreement, either the Executive or the Company shall deliver to the other written notice of his or its intention not to continue in effect this Agreement, in which case this Agreement shall terminate as of December 31 of the year in which such
notice is given (the “Term”). 
 4. Duties. During the Term: 
 (a) After the Effective Date and before the Promotion Time, the Executive shall report to the Company’s Chief Executive Officer.

 (b) On and after the Promotion Time, the Executive shall report to the Company’s Board and shall not be required to
report to any individual. 

 (c) The Executive will devote substantially his full working time and best efforts,
talents, knowledge and experience to serving the Company. However, the Executive may devote reasonable working time to activities such as supervision of personal investments and activities involving professional, charitable, educational, religious
and similar types of activities, speaking engagements and membership on other boards of directors, provided such activities do not interfere in any substantial way with the business of the Company; provided, further, that, the Executive may
serve on the board of directors of any other for-profit company only with the prior written approval of the Board or of a Board committee to which such approval shall have been delegated, which approval will not be unreasonably withheld. The time
involved in such activities shall not be treated as vacation time. The Executive shall be entitled to keep any amounts paid to him in connection with such activities (e.g., director fees and honoraria). 
 (d) The Executive will perform his duties diligently and competently and shall act in conformity with Company’s written and oral
policies and within the limits, budgets and business plans set by the Board. The Executive will at all times during the Term adhere to and obey all of the rules and regulations in effect from time to time relating to the conduct of executives of the
Company. Except as provided in (c) above, the Executive shall not engage in consulting work or any trade or business for his own account or for or on behalf of any other person, firm or company that competes, conflicts or interferes with the
performance of his duties hereunder in any way. 
 5. Place of Performance. In connection with the Executive’s employment by the
Company, the Executive shall be based at the Company’s offices in Johnstown, PA or Chicago, IL, as the Executive shall elect, except for required travel on the Company’s business. 
 6. Compensation and Related Matters. As compensation and consideration for the performance by the Executive of the Executive’s duties,
responsibilities and covenants pursuant to this Agreement, the Company will pay the Executive and the Executive agrees to accept in full payment for such performance the amounts and benefits set forth below: 
 (a) Salary. Commencing as of the Effective Date, the Company shall pay to the Executive an annual base salary (“Base
Salary”) of five hundred thousand dollars ($500,000). At the Promotion Time, Executive’s Base Salary shall increase, on a prospective basis, to five hundred fifty thousand dollars ($550,000). Thereafter, the Board, or such committee of the
Board as is responsible for setting the compensation of senior executive officers, shall review the Executive’s performance and Base Salary annually in January of each year, in light of competitive data, the Company’s performance, and
Executive’s performance, and determine whether to increase the Executive’s Base Salary on a prospective basis. The first review shall be in January 2008. Such adjusted annual salary then shall become the Executive’s “Base
Salary” for purposes of this Agreement. The Executive’s annual Base Salary shall not be reduced after any increase, without the Executive’s consent. The Company shall pay the Executive’s Base Salary according to payroll practices
in effect for all senior executive officers of the Company. 
 (b) Annual Bonus. The Executive will be eligible for an
annual cash bonus (the “Bonus”), based on performance, and calculated as a percentage of the Executive’s 

  

 - 2 - 

 
Base Salary. Initially, the Executive will participate in the Company’s current RONA plan at an 80% level, which would give the Executive the
opportunity of a Bonus payout equal to 120% of the Executive’s Base Salary. In any plan adopted by the Company to replace the current RONA plan, the Executive’s participation will have a potential payout at least equal to his potential
payout for 2007 under the current RONA plan. 
 The Company intends
that the Bonus will be paid within 2 1/2 months of the close of the Company’s fiscal year, but in no event
later than the end of the Company’s first fiscal quarter. In the event that payments are not made within 2 1/2 months of the close of the Company’s fiscal year, it is the Company’s intent that this Agreement be construed in a manner consistent with Section 409A of the Internal Revenue Code of 1986, as amended (the
“Code”). 
 (c) Equity Compensation. On the Effective Date, the Company shall award the
Executive forty thousand (40,000) shares of Restricted Stock in accordance with and subject to the terms of the FreightCar America, Inc. 2005 Long Term Incentive Plan, vesting in three equal annual installments beginning on the first
anniversary of the Effective Date. This Restricted Stock award would become fully vested upon a Change in Control. This award reflects both an ongoing long-term incentive and a consideration of certain unvested long-term incentives at Terex
Corporation (or any of its affiliates) (together referred to as “Terex”) that will not vest as a result of the Executive’s joining the Company. In any long-term incentive plan adopted by the Company in the future, the Executive’s
participation will have an annual target award equal to at least $1 million to the Executive if all goals, which shall be set in a manner intended to be achievable at target performance, are met. 
 (d) Signing Bonus. The Company will pay the Executive One hundred fifty thousand dollars ($150,000) on the Effective Date, which
amount shall be non-refundable to the Company but otherwise shall be treated as an advance against the Foregone Bonus Amount and the Foregone LTIP Amount that the Executive may receive under paragraph (e) below. 
 (e) Make Whole Agreement. It is anticipated that as a result of the Executive’s terminating his employment with Terex, Terex
will not pay the Executive an annual incentive bonus for the 2006 calendar year of $320,000, which otherwise would have been paid on or about March 15, 2007 (the “Foregone Bonus Amount”), and/or the long-term incentive award that
would have been payable on March 15, 2007, of one million seven hundred fifty thousand dollars ($1,750,000) (the “Foregone LTIP Amount”). Following the Effective Date, unless the Executive has notified the Chairman of the Board’s
Compensation Committee in writing that he has received the Foregone Bonus Amount and/or the Foregone LTIP Amount, the Company shall pay each such amount to the Executive on March 15, 2007. Upon receipt of each payment, the Executive shall
certify to the Company that Terex has not paid the Executive any amount in respect of the Foregone Bonus Amount or the Foregone LTIP Amount, as the case may be, or specify the amount of such payment, which shall be an offset against the
Company’s obligations under the applicable payment. 
  

 - 3 - 

 If subsequent to the receipt of the Foregone Bonus Amount or the Foregone LTIP Amount,

 (i) Terex makes any payment to the Executive in the nature of or similar to such amounts, the Executive shall immediately
notify the Chairman of the Board’s Compensation Committee in writing and turn over to the Company the amount of such payment from Terex up to the amount paid by the Company on a dollar-for-dollar basis; or 
 (ii) The Executive voluntarily terminates his employment with the Company before January 1, 2008, other than for Good Reason, the
Executive will repay the full amount of the Foregone LTIP Amount to the Company. 
 (f) Relocation. The Company will
reimburse the Executive’s reasonable moving expenses in relocating to the Chicago, Illinois metropolitan area, or an alternative corporate headquarters location if the Board of Directors selects a new headquarters location (which selection
shall be with the consent of the Executive); provided that, the Executive completes such move by the first anniversary of the Effective Date. Until the Executive relocates, the Company will pay or reimburse commuting expenses between the
Executive’s home in Connecticut and those locations at which the Executive needs to conduct business on the Company’s behalf. 
 Pursuant to this section, the Company shall reimburse the reasonable expenses of the Executive and his family for: (i) shipment of reasonable and customary household goods, with up to sixty (60) days
storage, from Connecticut to the Chicago metropolitan area, (ii) shipment of up to two automobiles from Connecticut to the Chicago metropolitan area, (iii) round trip air fare, lodging, meals and related expenses for up to two pre-move
home-finding trips for the Executive, his spouse and children under age 21, (iv) realtor’s commission on the sale of his residence in Connecticut, (v) closing costs on the purchase of the new residence and (vi) one-way air
transportation for the Executive and his family from Connecticut to Chicago. 
 (g) Automobile Allowance. During his
employment hereunder, the Company shall provide the Executive with the use of an automobile chosen by the Executive with lease payments of no more than seven hundred fifty dollars $750.00 per month throughout the Term (adjusted from time to time in
the discretion of the Board) and pay all insurance and maintenance expenses with respect to such automobile. 
 (h) Other
Benefits. The Executive shall be entitled to participate in or receive benefits under any employee benefit plan, arrangement or perquisite made available by the Company at any time during his employment hereunder to its executive employees
(collectively the “Benefit Plans”), including without limitation each retirement, 401(k) and profit sharing plan, group life insurance and accident plan, medical and dental insurance plans, and disability plan, subject to and on a basis
consistent with the terms, conditions and overall administration of such plans and arrangements; provided, however, that changes may be made to a plan in which executives of the Company participate, including termination of any such
plan or arrangement, if such changes do not result in a proportionately greater reduction in the rights of or benefits to the Executive as compared with any other executive of the Company or is required by law or a technical change. 
  

 - 4 - 

 (i) Expenses. The Executive shall be entitled to receive an advance or prompt
reimbursement for all reasonable travel and entertainment expenses or other out-of-pocket business expenses incurred by the Executive during the Term in fulfilling the Executive’s duties and responsibilities hereunder, including all expenses of
travel and living expenses while away from home on business or at the request of and in the service of the Company, provided that such expenses are incurred and accounted for in accordance with the policies and procedures established by the Company.

 (j) Vacation. During his employment hereunder, the Executive shall be entitled to paid vacations in each calendar
year, determined in accordance with the Company’s vacation policy but not less than four week per year. The Executive shall also be entitled to all paid holidays and personal days given by the Company to its executive employees. 
 (k) Country Club. During his employment hereunder, the Company shall pay membership and basic dues for the Executive at the
Sunnehanna Country Club or a similar club selected by the Executive in the Chicago, Illinois metropolitan area. 
 Any payments or benefits
payable to the Executive under this Section 6 in respect of any year during which the Executive is employed by the Company for less than the entire such year shall, unless otherwise provided herein or in the applicable plan or arrangement, be
prorated in accordance with the number of days in such year during which he is so employed; provided that annual dues or payments previously made shall not require a refund or offset against other amounts that may be due to the Executive.

 7. Termination. The Company, upon action by the Board, may terminate the Executive’s employment hereunder under the following
circumstances: 
 (a) Death. The Executive’s employment hereunder shall terminate upon his death. 
 (b) Disability. If, in the written opinion of a qualified physician selected by the Company, the Executive shall become unable to
perform his duties hereunder with reasonable accommodation due to physical or mental illness that continues for three months, the Company may terminate the Executive’s employment hereunder. 
 (c) Cause. The Company may terminate the Executive’s employment hereunder for Cause. For purposes of this Agreement, the
Company shall have “Cause” to terminate the Executive’s employment hereunder upon the Executive’s (i) willful and continued failure substantially to perform his material duties with Company (other than due to Disability), or
the commission of any activities constituting a material violation or material breach of any federal, state or local law or regulation applicable to the activities of Company, in each case, after notice thereof from the Board to the Executive and
(where possible) a reasonable opportunity for the Executive to cease and cure such failure, breach or violation in all respects, (ii) fraud, breach of fiduciary duty, dishonesty, misappropriation or other act that causes material damage to the
Company’s property or 

  

 - 5 - 

 
business, (iii) repeated absences from work such that the Executive is unable to perform his employment or other duties in all material respects, other
than due to Disability or a condition that with the passage of time would become a Disability, (iv) admission or conviction of, or plea of nolo contendere to, any crime that, in the reasonable judgment of the Board, adversely affects the
Company’s reputation or the Executive’s ability to carry out the obligations of his employment, (v) failure to reasonably cooperate with the Company in any internal investigation or administrative, regulatory or judicial proceeding,
after notice thereof from the Board to the Executive and a reasonable opportunity for the Executive to cure such non-cooperation or, (vi) act or omission by in violation or disregard of the Company’s policies, including but not limited to
the harassment and discrimination policies and Standards of Conduct of the Company then in effect, in such a manner as to cause significant loss, damage or injury to the property, reputation or employees of the Company. In addition, the
Executive’s employment shall be deemed to have terminated for Cause if, after the Executive’s employment has terminated, facts and circumstances are discovered that would have justified a termination for Cause. For purposes of this
Agreement, no act or failure to act on the Executive’s part shall be considered “willful” unless it is done, or omitted to be done, by him in bad faith or without reasonable belief that his action or omission was in the best interests
of Company. Any act or failure to act based upon authority given pursuant to a resolution duly adopted by the Board or based upon the advice of counsel for the Company shall be conclusively presumed to be done, or omitted to be done, in good faith
and in the best interests of the Company. 
 8. Compensation Upon Termination, Death or During Disability.

of the Executive’s death, (i) pay any Base Salary due to the Executive through the date of his death and any unreimbursed expenses and (ii) pay to the Executive’s legal representative any death benefits provided under any Benefit
Plans in accordance with their terms, and the Company shall, thereafter, have no further obligations to the Executive under this Agreement. 
 (b) Disability. During any period that the Executive fails to perform his duties hereunder as a result of incapacity due to physical or mental illness, the Executive shall continue to receive his Base Salary,
bonus and other benefits at the rate then in effect for such period (offset by any payments to the Executive received pursuant to disability benefit plans maintained by the Company) until his employment is terminated, and the Company shall,
thereafter, have no further obligations to the Executive under this Agreement. 
 (c) Cause or By Executive Other than for
Good Reason. If the Executive’s employment is terminated by the Company for Cause or by the Executive for other than Good Reason, the Company shall pay the Executive his Base Salary through the date of termination and any unreimbursed
expenses, and the Company shall, thereafter, have no further obligations to the Executive under this Agreement. For purposes of this Agreement, “Good Reason” shall mean, without the Executive’s written consent, the occurrence of any
of the following circumstances: (i) a Change in Control pursuant to which the buyer does not either assume this Agreement or otherwise agree to employ the 

  

 - 6 - 

 
Executive at or after the acquisition date on terms substantially comparable in the aggregate to this Agreement, (ii) unless such circumstances are

	 	9.	Restrictive Covenants 

 (a)
Confidential Information. The Executive understands that the Company possesses and will possess Confidential Information that is important to its business. The Company devotes significant financial, human and other resources to the
development of its products, its customer base and the general goodwill associated with its business and that the Company diligently maintains the secrecy and confidentiality of its Confidential Information. For purposes of this Agreement,
“Confidential Information” is information that was or will be developed, created, or discovered by or on behalf of the Company, or that became or will become known by, or was or is conveyed to the Company, which has commercial value in the
Company’s business. Confidential Information is sufficiently secret to derive economic value from its not being generally known to other persons. “Confidential Information” means any and all financial, technical, commercial or other
information concerning the business and affairs of the Company that is confidential and proprietary to the Company, including without limitation, (i) information relating to the Company’s past and existing customers and vendors and
development of prospective customers and vendors, including specific customer product requirements, pricing arrangements, payments terms, customer lists and other similar information; (ii) inventions, designs, methods, discoveries, works of
authorship, creations, improvements or ideas developed or otherwise produced, acquired or used by the Company; (iii) the Company’s proprietary programs, processes or software, consisting of but not limited to, computer programs in source
or object code and all related documentation and training materials, including all upgrades, updates, improvements, derivatives and modifications thereof and including programs and documentation in incomplete stages of design or research and
development; (iv) the subject matter of the Company’s patents, design patents, copyrights, trade secrets, trademarks, service marks, trade names, trade dress, manuals, operating instructions, training materials, and other industrial
property, including such information in incomplete stages of design or research and development; and (v) other confidential and proprietary information or documents relating to the Company’s products, business and marketing plans and
techniques, sales and distribution networks and any other information or documents which the Company reasonably regards as being confidential. 
 Executive understands that the Company possesses or will possess “Company Materials” that are important to its business. For purposes of this Agreement, “Company Materials” are documents or other
media or tangible items that contain or embody Confidential Information or any other information concerning the business, operations or future/strategic plans of the Company, whether such documents have been prepared by Executive or by others. In
consideration of Executive’s employment by the Company, the compensation received by Executive from the Company, and the Company’s agreement to give Executive access to certain Confidential Information, Executive agrees as follows:

 (i) All Confidential Information and trade secret rights, and other intellectual property and rights (collectively
“Rights”) in connection therewith will be the sole property of the Company. At all times, both during the Executive’s employment by the Company and after its termination for any reason, the Executive will keep in confidence and trust
and will not use or disclose any Confidential Information or anything relating to it without the prior written consent of an officer of the Company except as may be necessary and appropriate in the ordinary course of performing Executive’s
duties to the Company. 
  

 - 9 - 

 (ii) All Company Materials will be the sole property of the Company. The Executive agrees
that during Executive’s employment by the Company, Executive will not remove any Company Materials from the business premises of the Company or deliver any Company Materials to any person or entity outside the Company, except as Executive is
required to do so in connection with performing the duties of his employment. Executive further agrees that, immediately upon the termination of Executive’s employment by Executive or by the Company for any reason, or during Executive’s
employment if so requested by the Company, Executive will return all Company Materials, apparatus, equipment and other physical property, or any reproduction of such property, excepting only Executive’s copy of this Agreement. 
 (b) Noncompetition and Nonsolicitation. While employed by the Company and for a period of twelve consecutive months thereafter (or
twenty-four (24) consecutive months following the date of termination of employment where the Executive is being paid severance under Section 8(d) other than for non-renewal of this Agreement), the Executive will not directly or
indirectly: 
 (i) Contact, solicit, interfere with or divert any of the Company’s customers; 
 (ii) Participate or engage in, directly or indirectly (as an owner, partner, employee, officer, director, independent contractor,
consultant, advisor or in any other capacity calling for the rendition of services, advice, or acts of management, operation or control) in any business engaged in the manufacture of railcars in North America; and 
 (iii) Solicit any person who is employed by the Company for the purpose of encouraging that employee to join Executive as a partner,
agent, employee or otherwise in any business activity which is competitive with the Company. 
 For this purpose, service for
a company that is engaged in several businesses including the business of manufacturing railcars in North America, will not constitute a competing business if the Executive has no line authority for the business of manufacturing railcars and the
employees of such competing business do not report directly or through another individual to the Executive. 
  

 - 10 - 

 (c) Forfeitures. In the event that the Executive materially breaches any of the
restrictions in this Section 9, he shall forfeit all of the applicable payments and benefits under this Agreement, including but not limited to such payments and benefits pursuant to Section 8, and the Company shall have the right to
recapture and seek repayment of any such applicable payments and benefits under this Agreement. 
 (d) Intellectual
Property. “Inventions” includes all improvements, inventions, designs, formulas, works of authorship, trade secrets, technology, computer programs, compositions, ideas, processes, techniques, know-how and data, whether or not
patentable, made or conceived or reduced to practice or developed by the Executive, either alone or jointly with others, during the term of Executive’s employment, including during any period prior to the date of this Agreement. Except as
defined in this Agreement, all Inventions that Executive makes, conceives, reduces to practice or develops (in whole or in part, either alone or jointly with others) during his employment will be the sole property of the Company to the maximum
extent permitted by law. The Executive agrees to assign such Inventions and all Rights in them to the Company. Exemptions from this agreement to assign may be authorized in those circumstances where the mission of the Company is better served by
such action, provided that overriding obligations to other parties are met and such exemptions are not inconsistent with other Company policies. Further, Executive may petition the Company for license to make, market or sell a particular Invention.

 (e) Injunction. The Executive acknowledges that monetary damages will not be an adequate remedy for the Company in
the event of a breach of this Section 9, and that it would be impossible for the Company to measure damages in the event of such a breach. Therefore, Executive agrees that, in addition to other rights and remedies that the Company may have, the
Company is entitled to an injunction preventing Executive from any breach of this Section 9, and Executive hereby waives any requirement that the Company post any bond in connection with any such injunction. Executive further agrees that
injunctive relief is reasonable and necessary to protect a legitimate, protectible interest of the Company. 
 (f) Blue
Pencil. If any court determines that the covenants contained in this Section 9, or any part hereof, are unenforceable because of the duration or geographic scope of such provision, such court shall have the power to reduce the duration or
scope of such provision, as the case may be, to as close to the terms hereof as shall be enforceable and, in its reduced form, such provision shall then be enforceable. 
 (g) Survival. The restrictive covenants contained in this Section 9 shall survive the termination of this Agreement.

  

	 	10.	Miscellaneous. 

 (a)
Representations of the Executive. The Executive represents and warrants to the Company that this Agreement when executed by the Executive will not conflict with any other agreement or obligation of the Executive and that the Executive is not
bound by any agreement with any third party which would prohibit the Executive from his involvement with the Company or result in any liability to the Executive or to the Company.

be payable to him hereunder if he had continued to live, all such amounts, unless otherwise provided herein, shall be paid in accordance with the terms of this Agreement to the Executive’s devisee, legatee, or other designee or, if there be no
such designee, to the Executive’s estate.

the Company as maybe specifically designated by the Board. No waiver by either party hereto (the Company on one hand, and the Executive, on the other hand) at any time of any breach by the other party hereto of, or compliance with, any condition or
provision of this Agreement to be performed by such other party shall be deemed a waiver of similar or dissimilar provisions or conditions at the same or at any prior or subsequent time. The validity, interpretation, construction and performance of
this Agreement shall be governed by the laws of the State of Illinois without regard to its conflicts of law principles. The invalidity or enforceability of any provision or provisions of this Agreement shall not affect the validity or

Company agree that all such disputes shall be fully and finally resolved by binding arbitration conducted by the American Arbitration Association (“AAA”) in Chicago, Illinois in accordance with the AAA’s National Rules for the
Resolution of Employment Disputes, provided, however, that this arbitration provision shall not apply to, and the Company shall be free to seek, injunctive or other equitable relief with respect to any actual or threatened breach or violation by the
Executive of his obligations under Section 9 hereof in any court having appropriate jurisdiction. The Executive acknowledges that by accepting this arbitration provision he is waiving any right to a jury trial in the event of a covered dispute.
The arbitrator may, but is not required to, order that the prevailing party shall be entitled to recover from the losing party its attorneys’ fees and costs incurred in any arbitration arising out of this Agreement. The Company and the
Executive agree that the jurisdiction and venue for any disputes arising under, or any action brought to enforce (or otherwise relating to), Section 9 of this Agreement shall be exclusively in the courts in the State of Illinois, County of
Cook, including the Federal Courts located therein (should Federal jurisdiction exist), and the Company and the Employee and hereby submit and consent to said jurisdiction and venue. 
 (g) Withholding. All payments made to the Executive pursuant to this Agreement shall be subject to applicable withholding taxes, if
any, and any amount so withheld shall be deemed to have been paid to the Executive for purposes of amounts due to the Executive under this Agreement.
