For a period of 30 days after the date of a Valuation Event (the “Negotiation Period”), each party to this Agreement agrees to negotiate in good faith to reach agreement upon the Fair Market Value of such securities or property, as of the date of the Valuation Event. In the event that the parties are unable to agree upon the Fair Market Value of such securities or other property by the end of the Negotiation Period, then the Fair Market Value of such securities or property will be determined for purposes of this Agreement by an appraiser agreed upon by the parties or selected by the Company from a group of three (3) nationally recognized appraisers selected by a majority in interest of the Holders which are independent of each Holder (the “Appraiser”) and whose appraisal will be conclusive and binding on all parties to this Agreement.

exercise of the Warrants and outstanding options and other rights to acquire Common Stock or Preferred Stock having an exercise price per share less than the Fair Market Value thereof (as if such an event had occurred), without premium for control or liquidation preference or discount for minority interests, illiquidity, or restrictions on transfer. The costs of the Appraiser will be borne by the Company. In no event will the Fair Market Value of the Common Stock, Series D Convertible Preferred Stock or Other Securities be less than the per share consideration received or receivable with respect to the Common Stock, Series D Convertible Preferred Stock or Other Securities, as the case may be, in connection with a pending transaction involving a sale, merger, recapitalization, reorganization, consolidation, or share exchange, involving the Company, a dissolution of the Company, a sale of all or a majority of its assets, or similar transaction. In the case of determinations of the Fair Market Value of the Exchange Stock or any other security in question, references in this subparagraph (b) to Common Stock, Series D Convertible Preferred Stock or Other Securities, shall instead be deemed references to the Exchange Stock or such other security, as the case may be.

On the Closing Date, each of the MassMutual Investors agree to purchase from the Company at the purchase price set forth beneath the name of such Purchaser on the signature page of this Agreement and the Company agrees to issue to the MassMutual Investors, a warrant in substantially the form attached to this Agreement as Annex A-1 and incorporated in this Agreement by reference to purchase (a) the number of shares of Series D Convertible Preferred Stock set forth beneath the name of such MassMutual Investor on the signature page of this Agreement, plus (b) upon the exercise of the Contingent Options, the number of shares of Common Stock equal to the Contingent Options Adjustment Number, plus (c) upon the occurrence of an event described in Section 2.12 of this Agreement, the number of shares of Series D Convertible Preferred Stock or Common Stock provided for therein, as such number of shares purchasable under such Warrant shall be adjusted from time to time pursuant to the provisions of this Agreement, all in accordance with the terms and conditions of this Agreement (the warrants referred to in this sentence are hereinafter referred to as the “2001 MassMutual Investors Warrants”). On the Closing Date, RSTW agrees to purchase from the Company at the purchase price set forth beneath the name of RSTW on the signature page of this Agreement and the Company agrees to issue to RSTW, a warrant in substantially the form attached to this Agreement as Annex A and incorporated in this Agreement by reference to purchase (a) the number of shares of Series D Convertible Preferred Stock set forth beneath the name of RSTW as the number of warrant shares pertaining to the 2001 RSTW New Warrant on the signature page of this Agreement,

plus (b) upon the exercise of the Contingent Options, the number of shares of Common Stock equal to the Contingent Options Adjustment Number, plus (c) upon the occurrence of an event described in Section 2.12 of this Agreement, the number of shares of Series D Convertible Preferred Stock or Common Stock provided for therein, as such number of shares purchasable under such Warrant shall be adjusted from time to time pursuant to the provisions of this Agreement, all in accordance with the terms and conditions of this Agreement (the warrant referred to in this sentence is hereinafter referred to as the “2001 RSTW New Warrants”). On the Original Closing Date, RSTW purchased from AMHC at the purchase price of One Hundred Dollars ($100), and AMHC issued to RSTW, a warrant in the form attached to this Agreement as Annex A-2 and incorporated in this Agreement by reference to purchase the number of shares of AMHC’s Series D Convertible Preferred Stock and AMHC’s common stock provided for therein set forth, as such number of shares purchasable under such warrant are to be adjusted from time to time (the warrant referred to in this sentence is hereinafter referred to as the “1998 RSTW Warrant”). Effective as of September 25, 2000, RSTW purchased from AMHC at the purchase price of One Hundred Dollars ($100), and AMHC issued to RSTW, a warrant in the form attached to this Agreement as Annex A-3 and incorporated in this Agreement to purchase the number of shares of AMHC’s Series D Convertible Preferred Stock and AMHC’s Common Stock provided for therein, as such number of shares purchasable under such warrant are to be adjusted from time to time (the warrant referred to in this sentence is hereinafter referred to as the “2000 RSTW Warrant”; and together with the 1998 RSTW Warrant are hereinafter referred to as the “Original RSTW Warrants”). On the Closing Date, the Original RSTW Warrants will be converted, pursuant to the Advantage Merger, into one or more warrants which will be exchanged pursuant to this Agreement for Warrants in substantially the form attached to this Agreement as Annex A-4 and incorporated in this Agreement by reference to purchase (a) the number of shares of Series D Convertible Preferred Stock set forth beneath the name of RSTW on the signature page of this Agreement, plus (b) upon the exercise of the Contingent Options, the number of shares of Common Stock equal to the Contingent Options Adjustment Number, plus (c) upon each occurrence of an event described in Section 2.12 of this Agreement, the number of shares of Series D Convertible Preferred Stock or Common Stock provided for therein, as such number of shares purchasable under such warrant shall be adjusted from time to time pursuant to the provisions of this Agreement, all in accordance with the terms and conditions of this Agreement (the warrant referred to in this sentence is hereinafter referred to as the “2001 RSTW Merger Warrants”). Without limiting any other rights and benefits to which the 2001 RSTW Merger Warrant shall be entitled under the Advantage Merger or otherwise, the 2001 RSTW Merger Warrant also shall be treated as purchased and issued under this Agreement and entitled to all of the rights and benefits of this Agreement inuring to the Warrants purchased and issued hereunder (including, but not limited to, the rights and benefits inuring to such Warrants under the Stockholders’ Agreement and the Registration Rights Agreement).

2.02 Legend. The Company will deliver to Purchasers on the Closing Date one or more certificates representing the Warrants purchased by such Purchaser in such denominations as such Purchaser requests. Such certificates will be issued in the Purchasers name. It is understood and agreed that the certificates evidencing the Warrants will bear the following legend:

“THIS WARRANT AND THE SECURITIES ISSUABLE UPON EXERCISE HEREOF HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO OR FOR SALE IN CONNECTION WITH THE DISTRIBUTION HEREOF. THIS WARRANT AND THE SECURITIES ISSUABLE UPON EXERCISE HEREOF HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAWS, AND MAY NOT BE PLEDGED, SOLD, OFFERED FOR SALE, TRANSFERRED, OR OTHERWISE DISPOSED OF IN THE ABSENCE OF REGISTRATION UNDER OR EXEMPTION FROM SUCH ACT AND ALL APPLICABLE STATE SECURITIES LAWS.”

“THIS WARRANT AND THE SECURITIES ISSUABLE UPON EXERCISE HEREOF ARE SUBJECT TO THE TERMS AND PROVISIONS OF A WARRANT PURCHASE AGREEMENT (‘THE WARRANT PURCHASE AGREEMENT’), A STOCKHOLDERS’ AGREEMENT AND A REGISTRATION RIGHTS AGREEMENT, EACH DATED AS OF APRIL 30, 2001, AMONG KTC/AMG HOLDINGS CORP. (TO BE RENAMED THE KENAN ADVANTAGE GROUP, INC., AND REFERRED TO HEREIN AS THE ‘COMPANY’), RSTW PARTNERS III, L.P., MASSACHUSETTS MUTUAL LIFE INSURANCE COMPANY, MASSMUTUAL CORPORATE INVESTORS, MASSMUTUAL PARTICIPATION INVESTORS AND THE OTHER SIGNATORIES THERETO (AS SUCH AGREEMENTS MAY BE SUPPLEMENTED, MODIFIED, AMENDED, OR RESTATED FROM TIME TO TIME, THE ‘AGREEMENTS’). COPIES OF THE AGREEMENTS ARE AVAILABLE AT THE EXECUTIVE OFFICES OF THE COMPANY.”

2.03 Exercise Price. The Exercise Price per share will be $0.01 for each share of Series D Convertible Preferred Stock and $0.001 for each share of Common Stock and/or Other Securities covered by the Warrants; provided, however, that in no event will the aggregate Exercise Price for all of the shares of Series D Convertible Preferred Stock, Common Stock and/or Other Securities covered by the Warrants exceed $150.00, whether as a result of any change in the par value of the Series D Convertible Preferred Stock or the Common Stock, as a result of any change in the number of shares purchasable as provided in this Article II, or otherwise; provided, further, that such limitation of the aggregate Exercise Price will have no limiting effect whatsoever upon the amount or number of Warrant Shares for which the Warrants may be exercised.

2.04 Exercise.

(a) The Warrants may be exercised at any time or from time to time on or after the Closing Date until April 30, 2011, on any day that is a Business Day, for all or any part of the number of Issuable Warrant Shares purchasable upon its exercise. In order to exercise any Warrants, in whole or in part, the Holder will deliver to the Company at the address designated by the Company pursuant to Section 6.06 of this Agreement, (i) a written notice of such Holder’s election to exercise its Warrant, which notice will specify the number and type of Issuable Warrant Shares to be purchased pursuant to such exercise, (ii) payment of the Exercise Price, in an amount equal to the aggregate purchase

price for all Issuable Warrant Shares to be purchased pursuant to such exercise, and (iii) the Warrants. Such notice will be substantially in the form of the Subscription Form appearing at the end of the Warrants. Upon receipt of such notice, the Company will, as promptly as practicable, and in any event within five (5) Business Days, execute, or cause to be executed, and deliver to such Holder a certificate or certificates representing the aggregate number of full shares of Series D Convertible Preferred Stock and/or Common Stock, as the case may be, issuable upon such exercise, as provided in this Agreement. The stock certificate or certificates so delivered will be in such denominations as may be specified in such notice and will be registered in the name of such Holder. Warrants will be deemed to have been exercised, such certificate or certificates will be deemed to have been issued, and such Holder or any other Person so designated or named in such notice will be deemed to have become a holder of record of such shares for all purposes, as of the close of business on the date that such notice, together with payment of the Exercise Price and the Warrants, are received by the Company. If the Warrants have been exercised in part, the Company will, at the time of delivery of such certificate or certificates, deliver to such Holder new Warrants evidencing the rights of such Holder to purchase a number of Issuable Warrant Shares with respect to which the Warrants have not been exercised, which new Warrants will, in all other respects, be identical with the Warrants, or, at the request of such Holder, appropriate notation may be made on the Warrants and the Warrants returned to such Holder.

(b) Payment of the Exercise Price will be made, at the option of the Holder, by (i) wire transfer or certified or official bank check, (ii) cancellation of any debt owed by the Company or any Subsidiary to the Holder, or (iii) cancellation of warrant, valued at Fair Market Value. If the Holder surrenders a combination of cash or cancellation of any debt owed by the Company to the Holder of Warrants, the Holder will specify the respective number of shares of Series D Convertible Preferred Stock and/or Common Stock to be purchased with each form of consideration, and the foregoing provisions will be applied to each form of consideration with the same effect as if the Warrants were being separately exercised with respect to each form of consideration; provided, however, that a Holder may designate that any cash to be remitted to a Holder in payment of debt be applied, together with other monies, to the exercise of the portion of the Warrants being exercised for cash.

2.05 Taxes. The issuance of any Series D Convertible Preferred Stock and/or Common Stock upon the exercise of the Warrants will be made without charge to any Holder for any tax, other than income taxes assessed on such Holder, in respect of such issuance.

2.06 Warrant Register. The Company will, at all times while any of the Warrants remains outstanding and exercisable, keep and maintain at its principal office a register in which the registration, transfer, and exchange of the Warrants will be provided for. The Company will not at any time, except upon the dissolution, liquidation, or winding up of the Company, close such register so as to result in preventing or delaying the exercise or transfer of any Warrants.

2.07 Transfer. The Warrants and all options and rights under the Warrants are transferable, as to all or any part of the number of Issuable Warrant Shares purchasable upon its exercise, by the Holders of the Warrants, in person or by duly authorized attorney, on the books of the Company upon surrender of the Warrants at the principal offices of the Company, together with the form of transfer authorization attached to the Warrants duly executed, subject to compliance with the provisions of Sections 4.01 and 4.03 of the Stockholders’ Agreement. Absent any such transfer and subject to the Stockholders’ Agreement, the Company may deem and treat the registered Holders of the Warrants at any time as the absolute owners of the Warrants for all purposes and will not be affected by any notice to the contrary. If any Warrant is transferred in part, the Company will, at the time of surrender of such Warrant, issue to the transferee a Warrant covering the number of Issuable Warrant Shares transferred and to the transferor a Warrant covering the number of Issuable Warrant Shares not transferred. Notwithstanding the foregoing, before any public offering of any Capital Stock of the Company, no Holder shall transfer its Warrant Shares to any Person which the Board of Directors of the Company, in its good faith sole discretion, determines is a direct competitor of the Company, unless there has occurred either (i) an Event of Default (as defined in the Note Agreement) under Section 8.1(a) of the Note Agreement (other than a default by the Company in its obligation to purchase all or such portion of the Put Shares in a circumstance which does not constitute a Put Event Exercise Payment Default) or Section 8.1(g) of the Note Agreement or (ii) a Put Event Exercise Payment Default.

2.08 Exchange Rights. At the option of any Holder at any time prior to the consummation of an Initial Public Offering of the Company, any such Holder may exchange its Warrants or Warrant Shares for fully paid and nonassessable shares (calculated as to each exchange to the nearest 1/10,000 of a share and rounded upward to the next 1/10,000) of any class of capital stock of any Subsidiary of the Company that on the date of receipt of the Exchange Notice has a class of capital stock which is publicly traded (any such Subsidiary will be referred to in this Agreement as the “Exchange Company” and the class of capital stock of any such Subsidiary which is publicly traded will be referred to in this Agreement as “Exchange Stock”). Each $1,000 worth of Warrants or Warrant Shares (valued at Fair Market Value on the date that the Exchange Notice was sent), will be exchangeable for $1,000 worth of Exchange Stock (valued at Fair Market Value on the date that the Exchange Notice was sent). To exchange Warrants or Warrant Shares into Exchange Stock, the Holder will surrender at the principal office of the Exchange Company the Warrants or certificate or certificates evidencing the Warrant Shares duly endorsed or assigned to the Company, and give written notice to the Company at such office that it elects to exchange such Warrants or Warrant Shares (the “Exchange Notice”). Warrants or Warrant Shares will be deemed to have been exchanged immediately prior to the close of business on the day of the surrender for exchange in accordance with the foregoing provisions, and the Person or Persons entitled to receive the Exchange Stock issuable upon any such exchange will thereupon be treated for all purposes as the record holder or holders of the Exchange Stock. As promptly as practicable on or after the exchange date, the Exchange Company will issue and deliver a certificate or certificates for the number of full shares of Exchange Stock issuable upon exchange to the Person or Persons entitled to receive such shares. Upon exchange of any Issued Warrant Shares, the Company will pay or make with respect to Issued Warrant Shares any dividends or other distributions that have been declared on

the Warrant Shares in kind or cash (including without limitation the Dilution Fee described in Section 2.09 of this Agreement), as the case may be. If any Holder exchanges its Warrants or Warrant Shares for shares of Exchange Stock pursuant to this Section 2.08, such Holder will have all of the rights set forth in this Article II, except that for the purposes of this Article II the term “Company” will refer instead to the Exchange Company and the term “Registrable Securities” will refer to the shares of Exchange Stock held by such Holder.

2.09 Dilution Fee. In the event that, during the term of the Warrants, the Company pays any cash dividend or makes any cash distribution to any holder of any class of its Capital Stock with respect to such Capital Stock, other than a distribution pursuant to Section 2 or Section 3 of the Certificate of Designations, each Holder of the Warrants will be entitled to receive in respect of its Warrants a dilution fee in cash (the “Dilution Fee”) on the date of payment of such dividend or distribution, which Dilution Fee will be equal to the highest amount per share paid to any class of Capital Stock times the number of Issued Warrant Shares then owned by such Holder plus the number of Issuable Warrant Shares then owned by such Holder, less the amount of such dividend or distribution otherwise paid to such Holder as a result of its ownership of such Capital Stock.

2.10 Put Option. The Company hereby grants to each Holder an option to sell to the Company, and the Company is obligated to purchase from each Holder under such option (the “Put Option”), all (or such portion as is designated by any such Holder) of the Put Shares. The Put Option will be effective at any time or times after the fifth (5th) anniversary of the date of this Agreement, or at any time or times upon or after the occurrence of any of the following events (the “Put Option Period”):

(a) AMGI and Kenan shall cease to own and control, beneficially and of record, 100% of the issued and outstanding shares of capital stock of X. XxXxxxxx, Inc., Evalia Acquisition Corp., Petro-Chemical Transport, Inc., North Canton Transfer Co., Geni Management Corporation or Advantage Tank Lines, Inc., free and clear of all Liens other than Permitted Liens or Geni Management Corporation shall cease to own and control, beneficially and of record, 100% of the issued and outstanding shares of capital stock of Geni Transport, Inc.; or

(b) AMHC shall cease to own and control, beneficially and of record, 100% of the issued and outstanding shares of capital stock of AMGI (except as a result of a merger of AMHC with and into the Company or AMGI); or

(c) the Company shall cease to own and control, beneficially and of record, 100% of the issued and outstanding shares of capital stock of AMHC (or, upon a merger of AMHC with and into the Company, AMGI) and Kenan, free and clear of all Liens other than Permitted Liens; or

(d) any sale or other disposition of all or substantially all of the consolidated assets of AMGI and Kenan in a single transaction or series of related transactions; or

(e) prior to the consummation of an Initial Public Offering, (i) Persons holding Capital Stock of the Company as of the Closing Date and their Permitted Transferees (as such term is defined in the Stockholders’ Agreement in effect on the date hereof), determined on a fully diluted basis, shall cease to own at least 51% of all shares of Capital Stock of the Company or (ii) Sterling and/or RFE shall cease to have the power to appoint a majority of the Company’s Board of Directors; or

(f) the acquisition by any Person, or two or more Persons acting in concert (other than the Persons described in clause (e) above), of beneficial ownership (within the meaning of Rule 13d-3 of the Commission under the Exchange Act) of 40% or more of the outstanding shares of capital stock of the Company; or

(g) Sterling ceases to be represented on the Board of Directors of the Company; or

(h) (i) more than two of the Sterling Principals shall (other than by reason of death or disability) cease to have (together with the other Sterling Principals) the right or ability by voting power, contract or otherwise to direct or cause the direction of the management and policies of Sterling or (ii) more than two of the Sterling Principals shall (other than by reason of death or disability) cease to be managing members of the sole general partner of Sterling; or

(i) a merger (other than a merger of AMHC with and into the Company), consolidation, share exchange, or similar transaction involving the Company or sale in one or more related transactions of all or substantially all of the assets, business, or revenue or income generating operations of the Company, including the stock or assets of its Subsidiaries (collectively, a “Sale Event”) or any substantial change in the type of business conducted by the Company; or

(j) after the occurrence and during the continuance of an Event of Default (as defined in the Note Agreement) pursuant to Section 8.1(a) of the Note Agreement or any failure of the Company to perform any of its obligations hereunder, and such failure shall continue uncured for a period of thirty (30) days following the earlier of the date the Company is notified of such failure by a Holder or the date upon which the Company first knew or should have known of such failure; provided, however, that the Put Option Period will continue with respect to such event, even after such default has been cured, if notice of exercise is provided pursuant to this Article II during the existence of such Event of Default or failure of performance hereunder; or

(k) payment in full of the Note, unless such payment is made out of the proceeds of an Initial Public Offering;

provided, that, (i) the Put Option shall expire upon the consummation of an Initial Public Offering to the extent that it has not been exercised prior thereto and (ii) for purposes of clauses (a), (b) or (c) above, a merger or consolidation of AMGI or Kenan into, or with, any of their

Subsidiaries, or any Subsidiary with or into any other Subsidiary, shall not cause the Put Option Period to begin.

2.10.1 Put Price. In the event that any Holder exercises the Put Option, the price (the “Put Price”) to be paid to each such Holder pursuant to this Agreement will be cash in the sum of the amount determined by (a) adding the products determined by multiplying the Fair Market Value per share of each of the Series D Convertible Preferred Stock and Common Stock as of the end of the month immediately preceding the date notice is given of the exercise of the Put Option pursuant to Section 2.10.2 of this Agreement times the number of shares of such Series D Convertible Preferred Stock and Common Stock that would be issuable on such date upon the exercise of the Warrants for which the Put Option is being exercised by such Holder and subtracting therefrom (b) an amount equal to the Exercise Price times the number of shares of Series D Convertible Preferred Stock and/or Common Stock issuable pursuant to any unexercised portion of the Warrants for which the Put Option is being exercised by such Holder; provided, however, in the event (i) a Sale Event with a bona fide third party occurs which is a Qualified Sale (or would have constituted a Qualified Sale but for the fact that it is not a sale of all of the outstanding shares of Capital Stock of the Company) and (ii) one or more Holders elects to exercise the Put Option and either (A) such Holder(s) have agreed to the price to be paid to holders of Common Stock and all classes of Preferred Stock in connection with such Sale Event or (B) the Holders have been provided with a “fairness opinion” from an investment banker agreed upon by the parties hereto or selected by the Company from a group of three (3) nationally recognized investment bankers selected by a sixty-six and two-thirds percent (66 2/3%) in interest of the Holders which are independent of each Holder, stating that the price per Warrant Share to be received by the Holders in the Sale Event is fair to such Holders from a financial point of view, the Put Price to be paid to each such Holder pursuant to this Agreement will be cash in the sum of the amount determined by multiplying the price per share of such Warrant Shares set by the Company in connection with such Sale Event times the number of Warrant Shares for which the Put Option is being exercised by such Holder, except that in the case of a Qualified Sale in which the Purchase Price being paid for the Company’s Capital Stock is being paid in Qualified Public Securities the Put Price to be paid to each such Holder pursuant to this Agreement will be paid in Qualified Public Securities in the exchange ratio specified in such “fairness opinion”, but in no event shall the Holders exercising the Put Option receive less cash (other than cash paid in respect of fractional shares) as a percentage of the per-share consideration received by them in respect of their Series D Convertible Preferred Stock or Common Stock, as the case may be, than the other holders of Preferred Stock or Common Stock, respectively, received in such Qualified Sale. The Put Price shall be determined without premium for control or discount for minority interests, illiquidity, or restrictions on transfer.

2.10.2 Exercise of Put Option. The Put Option may be exercised during the Put Option Period with respect to all or any portion of the Put Shares, by such Holder giving notice to the Company and to each other Holder, either prior to or during the Put Option Period, of the Holder’s election to exercise the Put Option, and the date of the Put Option Closing, which will be not less than ninety (90) days after the date of such notice. The Company will provide each Holder desiring to exercise its Put Option the name and address of each other Holder. Notwithstanding the foregoing, if a Holder receives such notice of another Holder’s exercise of

such other Holder’s Put Option, the Holder receiving such notice may elect to exercise its Put Option and designate a Put Option Closing simultaneous and pari passu with that of such other Holder if the Holder electing to exercise its Put Option under the circumstances described in this sentence gives notice of its election to the Company and such other Holder at least forty-five (45) days prior to such Put Option Closing.

2.10.3 Certain Remedies.

(a) In the event that the Company defaults in its obligation to purchase all or any portion of the Put Shares upon exercise of the Put Option and either (i) such Holder’s exercise of the Put Option was based upon the occurrence of an event described in any of subsections (a), (b), (c), (d), (e), (f), (g), (h), (i), (j) and (k) of Section 2.10 of this Agreement, or (ii) an Initial Public Offering has been consummated (whether or not it was or is consummated prior to or subsequent to the date of such default), in addition to any other rights or remedies of each Holder, the unpaid portion of the Put Price will bear interest at the rate of fifteen percent (15%) per annum at all times from and after the date of such default. In the event that the Company is prohibited by the terms of the Senior Loan Agreement from paying all or any portion of the Put Price in cash upon the exercise of the Put Option during the period after the fifth (5^th) anniversary of the Closing Date but prior to the eighth (8^th) anniversary of the Closing Date in any case other than that described in the immediately preceding sentence, the Company may issue a Qualified Put Note (as defined below) to the extent not paid in cash because of such prohibition. The Qualified Put Notes will be subordinate to the Senior Debt (as such term is defined in Senior Subordination Agreement) pursuant to the terms of the Senior Subordination Agreement.

(b) As used in this Agreement, “Qualified Put Note” means a promissory note made by the Company payable to the Holders which have exercised their Put Option but have not been paid in full in cash with respect thereto because of the operation of the second sentence of subparagraph (a) of Section 2.10.3, which promissory note shall be guarantied by Kenan, AMHC, AMGI, and all other present and future Subsidiaries of the Company and all other present and future obligors or guarantors of all or any part of the Senior Subordinated Obligations, and have the same rights, benefits, protections and priority as the Note, except as follows:

(i) the scheduled maturity date upon which all interest and principal thereon is due and payable is the earliest of (A) the eighth (8^th) anniversary of the Closing Date, (B) the earliest date upon which payment thereunder would not be prohibited from being made under the Senior Loan Agreement, and (C) the date of the repayment in full of the Senior Debt (as such term is defined in the Note Agreement), and prior to such date no portion of the principal, interest or other amounts owing thereunder shall become due, whether in cash, kind, other securities or otherwise; and

(ii) the rate of interest which accrues on the unpaid amount thereof is (A) 15.0% per annum during the first 12 month period following the date of exercise of the Put Option which gave rise to the Put Price covered by the such promissory note, (B) 17.5%

per annum during the next ensuing 9 month period following the date of exercise of the Put Option which gave rise to the Put Price covered by the such promissory note, and (C) 20.0% per annum thereafter.

(c) In addition to, and not in limitation of, any and all other rights and remedies of the Holders under this Agreement or otherwise, in the event that at any time all or any portion of any Put Price has not been paid in full in cash for any reason whatsoever (including, but not limited to the operation of any provision of this Section 2.10.3) at the time of any exercise by any Holder of the Put Option, the Company, Sterling Investment Partners, L.P. and RFE Investment Partners shall promptly commence and diligently pursue the sale of the Company in accordance with the agreement delivered pursuant to Section 5.06 of this Agreement.

2.10.4 Put Option Closing. The closing for the purchase and sale of all or such portion of the Put Shares as to which the Holder has notified the Company of its intention to exercise the Put Option, will take place at the office of the Company on the date specified in such notice of exercise (a “Put Option Closing”). At any Put Option Closing, to the extent applicable, the Holder of the Put Shares will deliver the certificate or certificates evidencing the Put Shares being purchased, duly endorsed in blank. In consideration therefor, the Company will deliver to the Holder the Put Price, which will be payable in cash.

2.11 Call Option. Each Holder hereby severally grants to the Company an option to require such Holder to sell to the Company, and each Holder is obligated to sell to the Company under this option (the “Call Option”), all of its Warrants and its Warrant Shares. The Call Option will be effective after the sixth (6th) anniversary of the date of this Agreement but shall expire upon the consummation of an Initial Public Offering (the “Call Option Period”).

2.11.1 Call Price. In the event that the Company exercises the Call Option, the exercise price to be paid in cash to each Holder will be equal to the Put Price determined in accordance with Section 2.10.1 of this Agreement, except that the Call Option will be exercised with respect to the entire Warrant and all Warrant Shares, and will be increased by an amount in cash equal to any Excess Consideration received within two hundred seventy (270) days following the exercise of the Call Option due to an Adjustment Event.

2.11.2 Exercise of Call Option. The Call Option may be exercised during the Call Option Period with respect to all of the Warrants and the Warrant Shares of all Holders, by the Company giving notice to each Holder during the Call Option Period of the election of the Company to exercise the Call Option, and the date of the Call Option Closing (as defined below), which in all events will be at least sixty (60) days but no more than ninety (90) days after the date of such notice.

2.11.3 Call Option Closing. The closing for the purchase and sale of all of the Warrants and Warrant Shares that the Company has elected to purchase under this Agreement, will take place at the office of the Company, on the date specified in such notice of exercise (the “Call Option Closing”). At the Call Option Closing, the Holders of the Warrants will deliver the

Warrants and the certificate or certificates representing the Warrant Shares, duly endorsed in blank. In consideration therefor, the Company will deliver to each Holder the purchase price, which will be payable in immediately available funds.

2.12 Adjustments to Number of Shares Purchasable.

(a) The Warrants will be exercisable for the number of shares of Series D Convertible Preferred Stock and Common Stock in such manner that, following the complete and full exercise of the Warrants of each Holder, the amount of Series D Convertible Preferred Stock and Common Stock issued to all Holders will equal 6,731 shares of Series D Convertible Preferred Stock plus up to 44,037 shares of Common Stock for the Contingent Option Adjustment Number, subject to antidilution adjustments from time to time, and as adjusted, to the extent necessary, to give effect to the following events:

(i) In case at any time or from time to time, the holders of any class of Capital Stock have received, or (on or after the record date fixed for the determination of shareholders eligible to receive) have become entitled to receive, without payment therefor:

(A) consideration (other than cash) by way of dividend or distribution; or

(B) consideration (including cash) by way of spin-off, split-up, reclassification (including any reclassification in connection with a consolidation or merger in which the Company is the surviving corporation), recapitalization, combination of shares into a smaller number of shares, or similar corporate restructuring;

other than additional shares of Series D Convertible Preferred Stock or Common Stock issued to holders thereof in a transaction for which adjustments are provided for in Sections 2.12(a)(ii) and (iii) of this Agreement, then, and in each such case, the Holders, on the exercise of the Warrants, will be entitled in addition to receive for each share of Series D Convertible Preferred Stock or Common Stock, as the case may be, issuable under the Warrants as of the record date fixed for such distribution, the amount of consideration equal to the quotient determined by (i) dividing the amount of such distribution by the Purchaser Ownership Percentage and subtracting from such amount the amount of such distribution and (ii) then dividing the remainder by the number of shares of Series D Convertible Preferred Stock then issuable to such Holder upon exercise of the Warrants less the amount of any Dilution Fee actually and indefeasibly paid to such Holders. All such consideration receivable upon exercise of the Warrants with respect to such a distribution will be deemed to be outstanding and owned by such Holder for purposes of determining the amount of consideration to which such Holder is entitled upon exercise of the Warrants with respect to any subsequent distribution.

(ii) If at any time there occurs any stock split, stock dividend, reverse stock split, or other subdivision of the Series D Convertible Preferred Stock or the Common Stock, then the number of shares of Series D Preferred Stock or Common Stock, as the case may be, to be received by the Holder of the Warrants and the Exercise Price, subject to the limitations set forth in this Agreement, will be proportionately adjusted.

(iii) In case of any reclassification or change of outstanding shares of any class of Capital Stock (other than a change in par value, or from par value to no par value, or from no par value to par value), or in the case of any consolidation of the Company with, or merger or share exchange of the Company with or into, another Person, or in case of any sale of all or substantially all of the property, assets, business, income or revenue generating capacity, or goodwill of the Company, the Company, or such successor or other Person, as the case may be, will provide that the Holder of the Warrants and/or the Warrant Shares will thereafter be entitled in addition to receive the highest per share kind and amount of consideration received or receivable (including cash) upon such reclassification, change, consolidation, merger, share exchange, or sale had they owned such Series D Convertible Preferred Stock and Common Stock immediately prior to such reclassification, change, consolidation, merger, share exchange, or sale (as adjusted pursuant to Section 2.12(a)(i) of this Agreement and otherwise in this Agreement). Any such successor Person, which thereafter will be deemed to be the Company for purposes of the Warrants and the Warrant Shares, will provide for adjustments that are as nearly equivalent as may be possible to the adjustments provided for by this Section 2.12 of this Agreement; provided, however, that the foregoing portion of this sentence shall not apply in the case of a Qualified Sale in which (i) the Holders have been provided with a “fairness opinion” from a nationally recognized investment banker selected by the Company (other than one as to which a majority in interest of the Holders has a reasonable objection), (ii) the consideration received by the Holders in exchange for all of the Warrants and the Warrant Shares consists exclusively of Qualified Public Securities of the kind and amount of consideration received or receivable by the holders of the Common Stock and the Preferred Stock and/or cash in an amount equal to the Fair Market Value of such consideration, and (iii) (A) the Holders have been afforded the opportunity to exercise new Put Option rights on the same terms and conditions as described under Section 2.10 of this Agreement, mutatis mutandis with respect thereto (notwithstanding the fact that the unexercised portion of the Put Option has otherwise expired upon the consummation of an Initial Public Offering), (B) in the event that the Holders have exercised any such rights hereof prior to or in connection with any such Qualified Sale, such Holders have been paid in full in cash in respect thereof prior to or simultaneously with the closing of such Qualified Sale, and (C) no restrictions shall at such time be in existence on the Holders with respect to such cash or such payment under the terms of any subordination agreement or similar

agreement, document or instrument (e.g., the Holders are not prohibited from receiving any such cash or payment or obligated to turnover any such cash or payment to any senior lender to the Company or any Subsidiary).

(iv) If at any time after the Closing Date the Company issues or sells any shares of any Capital Stock (other than Permitted Stock, shares of Capital Stock upon exercise, exchange or conversion of a security which, at the time of its issuance or sale, was issued at a per unit price which either (a) was less than the Exercise Price or the then current Fair Market Value per share of Common Stock, and as a result, an adjustment was made pursuant to this clause (iv) or (b) was equal to or greater than the Exercise Price or the then current Fair Market Value per share of Common Stock, or in a situation covered by subparagraph (iii) above or in a Qualified Secondary Offering), at a per unit or share price less than the Exercise Price or the then current Fair Market Value per share of Common Stock immediately prior to the time such Capital Stock is issued or sold (the “Additional Securities”), then:

(A) the Exercise Price will be reduced (but not increased) to the lower of the prices calculated by:

(I) dividing (x) an amount equal to the sum of (1) the number of shares of Capital Stock outstanding on a fully diluted basis immediately prior to such issuance or sale multiplied by the then existing Exercise Price plus (2) the aggregate consideration, if any, received by the Company upon such issuance or sale, by (y) the total number of shares of Capital Stock outstanding immediately after such issuance or sale; and

(II) multiplying the then existing Exercise Price by a fraction, the numerator of which is (x) the sum of (1) the number of shares of Capital Stock outstanding on a fully diluted basis immediately prior to such issuance or sale, multiplied by the Fair Market Value per share of Common Stock immediately prior to such issuance or sale, plus (2) the aggregate consideration received by the Company upon such issuance or sale, divided by the total number of shares of Capital Stock outstanding immediately after such issuance or sale, and the denominator of which is the (y) Fair Market Value per share of Common Stock immediately prior to such issuance or sale (for purposes of this subsection (II), the date as of which the Fair Market Value per share of Common Stock will be computed will be the earlier of the date upon which the Company will (aa) enter into a firm contract for the issuance of such shares, or (bb) issue such shares); and

(B) the number of shares of Series D Convertible Preferred Stock and Common Stock (other than shares of Common Stock issuable pursuant to Section 2.12(b), if the Contingent Options have not been exercised) for which any of the Warrants may be exercised at the Exercise Price resulting from the adjustment described in subsection (A) above will be equal to the product of the number of shares of Series D Convertible Preferred Stock and Common Stock (other than shares of Common Stock issuable pursuant to Section 2.12(b), if the Contingent Options have not been exercised), as the case may be, purchasable under such Warrants immediately prior to such adjustment multiplied by a fraction, the numerator of which is the Exercise Price in effect immediately prior to such adjustment and the denominator of which is the Exercise Price resulting from such adjustment.

(v) In case any event occurs as to which the preceding Sections 12.12(a)(i) through (iv) of this Agreement are not strictly applicable, but as to which the failure to make any adjustment would not fairly protect the purchase rights represented by the Warrants in accordance with the essential intent and principles of this Agreement, then, in each such case, unless such firm is otherwise agreed to by the parties hereto, the Company shall select an independent investment bank or firm of independent public accountants, such investment bank or firm of independent public accountants to be selected from a group of three nationally recognized investment banks or firms of public accountants chosen by a majority-in-interest of the Holders, which will give its opinion as to the adjustment, if any, on a basis consistent with the essential intent and principles established in this Agreement, necessary to preserve the purchase rights represented by the Warrants. Upon receipt of such opinion, the Company will promptly deliver a copy of such opinion to the Holder and will make the adjustments described in such opinion. The fees and expenses of such investment bank or independent public accountants will be borne by the Company.

(b) In addition to, and not in limitation of, the other provisions of this Section 2.12, upon the exercise of each Contingent Option the number of shares of Common Stock for which the Warrants shall be exercisable, and the number of Warrant Shares, shall be increased to also include an additional number of shares of Common Stock equal to the Contingent Options Adjustment Number. As used herein, “Contingent Options Adjustment Number” means a number of shares of Common Stock equal to the sum of (a) the quotient of the number of shares of Common Stock issued upon the exercise of the Contingent Options divided by the Purchaser Ownership Percentage minus (b) the number of shares of Common Stock issued upon the exercise of the Contingent Options.

(c) The Company will not by any action including, without limitation, amending, or permitting the amendment of, the charter documents, bylaws, or similar instruments of the Company or through any reorganization, reclassification, transfer of

assets, consolidation, merger, share exchange, dissolution, issue or sale of securities, or any other similar voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Agreement or the Warrants, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate to protect the rights of the Holders against impairment or dilution. Without limiting the generality of the foregoing, the Company will (i) take all such action as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable shares of Series D Convertible Preferred Stock and/or Common Stock, as the case may be, free and clear of all liens, encumbrances, equities, and claims and (ii) use its best efforts to obtain all such authorizations, exemptions, or consents from any public regulatory body having jurisdiction over the Company as may be necessary to enable the Company to perform its obligations under the Warrants. Without limiting the generality of the foregoing, the Company represents and warrants that the board of directors of the Company has determined the Exercise Price to be adequate and the issuance of the Warrants to be in the best interests of the Company.

(d) Any calculation under this Section 2.12 will be made to the nearest one ten-thousandth (1/10,000) of a share and the number of Issuable Warrant Shares resulting from such calculation will be rounded up to the next one ten-thousandth (1/10,000) share of the Series D Convertible Preferred Stock and/or Common Stock, as the case may be, comprising Issuable Warrant Shares.

2.13 Lost, Stolen, Mutilated or Destroyed Warrants. Upon receipt of evidence satisfactory to the Company of the loss, theft, mutilation or destruction of a Warrant, and, in the case of any such loss, theft or destruction, upon delivery of a bond of indemnity in such form and amount as shall be reasonably satisfactory to the Company or, in the event of such mutilation upon surrender and cancellation of a Warrant, the Company, without charge to the Holder thereof, will make and deliver a new Warrant of like tenor and the same series in lieu of such lost, stolen, destroyed or mutilated Warrant. If any such lost, stolen or destroyed Warrant is owned by a Purchaser or any other Holder whose credit is satisfactory to the Company, then the affidavit of an authorized officer of such owner setting forth the fact of loss, theft or destruction and of its ownership of the Warrant at the time of such loss, theft or destruction shall be accepted as satisfactory evidence thereof, and no further indemnity shall be required as a condition to the execution and delivery of a new Warrant, other than a written agreement of such owner (in form reasonably satisfactory to the Company) to indemnify the Company.

2.14 Stock Legend. The Warrants and the Warrant Shares have not been registered under the Securities Act or qualified under applicable state securities laws. Accordingly, unless there is an effective registration statement and qualification respecting the Warrants and the Warrant Shares under the Securities Act or under applicable state securities laws at the time of exercise of a Warrant, any stock certificate issued pursuant to the exercise of a Warrant will bear the following legend:

“THE SHARES REPRESENTED BY THIS CERTIFICATE (A) HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAWS, AND MAY NOT BE PLEDGED, SOLD, OFFERED FOR SALE, TRANSFERRED, OR OTHERWISE DISPOSED OF IN THE ABSENCE OF REGISTRATION UNDER OR EXEMPTION FROM SUCH ACT AND ALL APPLICABLE STATE SECURITIES LAWS AND (B) ARE SUBJECT TO THE TERMS OF AND PROVISIONS OF A WARRANT PURCHASE AGREEMENT, A STOCKHOLDERS’ AGREEMENT AND A REGISTRATION RIGHTS AGREEMENT, EACH DATED AS OF APRIL 30, 2001 AMONG KTC/AMG HOLDINGS CORP. (THE “COMPANY”), RSTW PARTNERS III, L.P., MASSACHUSETTS MUTUAL LIFE INSURANCE COMPANY, MASSMUTUAL CORPORATE INVESTORS, MASSMUTUAL PARTICIPATION INVESTORS AND THE OTHER SIGNATORIES THERETO (AS SUCH AGREEMENTS MAY BE SUPPLEMENTED, MODIFIED, AMENDED, OR RESTATED FROM TIME TO TIME, THE “AGREEMENTS”). COPIES OF THE AGREEMENTS ARE AVAILABLE AT THE OFFICES OF THE COMPANY.”

The annual audit report required by this Agreement will not be qualified by or make reference to any disclosure that the Company or any Subsidiary may not continue as a going concern or otherwise be qualified or limited because of restricted or limited examination by the accountant of any portion of any of the records of the Company or any Subsidiary.

4.02 Laws. The Company will, and will cause any and all Subsidiaries to, comply with all applicable statutes, regulations, and orders of the United States, domestic and foreign states, and municipalities, agencies, and instrumentalities of the foregoing applicable to the Company or any Subsidiary, the non-compliance with which would have a material adverse effect on the Company and its Subsidiaries taken as a whole. The Company and its Subsidiaries may, however, contest or dispute any acts, rules, regulations, orders and directions of those bodies or officials in any reasonable manner, provided that adequate reserves with respect thereto are established to the reasonable satisfaction of the Purchasers.

4.03 Inspection. Upon at least five (5) days’ notice and during business hours, the Company will, and will cause any and all Subsidiaries to, permit any representative designated by the Holders to (a) visit and inspect any of the properties of the Company or any Subsidiary (provided that the costs and expenses incurred by the Holders in connection with any visit and inspection of any properties of any Subsidiary which at such time is not a material Subsidiary shall be borne by such Holders); (b) examine the corporate and financial records of the Company or any Subsidiary and make copies thereof or extracts therefrom; and (c) discuss the affairs, finances, and accounts of the Company or any Subsidiary with the directors, officers, key employees, and independent accountants of the Company.

Each Holder agrees that such Holder and its designee shall not disclose any confidential information obtained in connection with this Section 4.03 to any Person (other than Persons in a confidential relationship with such Holder) unless such Person has agreed in writing to maintain such information confidential; provided, however, that nothing herein shall be deemed to prevent the disclosure of any confidential information if such disclosure is (i) required to be made in a judicial, administrative or governmental proceeding, (ii) required by any applicable law or regulation, (iii) made to any governmental agency or regulatory body having or claiming authority over any aspect of such Holder’s or its Affiliates’ businesses in connection with the exercise of such authority or claimed authority, (iv) subject to subpoena, or (v) made, on a confidential basis as such Holder deems reasonably necessary or appropriate to any of its investors, any bank or financial institution and/or counsel to or other representatives of such investors, bank or financial institution. Such regular meetings will be held at least quarterly. The Company will reimburse at least one (1) person designated from time to time by the MassMutual Investors as a whole and up to two (2) persons designated from time to time by RSTW for reasonable out-of pocket expenses

incurred in traveling to and attending such meetings.

(a) the Company shall not permit to occur any (i) amendment, alteration, or modification of the Bylaws of the Company, as constituted on the date of this Agreement, the effect of which, in the sole judgment of the Holders, would be to alter, impair, or affect adversely, either the rights and benefits of the Holders or the duties and obligations of the Company under this Agreement, the Warrants, the Stockholders’ Agreement or the Registration Rights Agreement or (ii) amendment, alteration, or modification of the Certificate of Incorporation, the Certificate of Designations, other charter or organizational documents of the Company, as constituted on the date of this Agreement or authorize or designate (through board of directors designation or otherwise) any class or series of any Capital Stock which rank on parity with or senior to the Series D Convertible Preferred Stock upon payment of dividends, liquidation or other distributions except to the extent necessary to comply with Sections 4.04(k) and 4.10 of this Agreement;

by Section 2.12 of this Agreement have been made); except that the Company shall be permitted to issue and sell Permitted Stock;

4.08 Notice.

(a) In the event of (i) any setting by the Company of a record date with respect to the holders of any class of Capital Stock for the purpose of determining which of such holders are entitled to dividends, repurchases of securities or other distributions, or any right to subscribe for, purchase or otherwise acquire any shares of Capital Stock or other property or to receive any other right; or (ii) any capital reorganization of the Company, or reclassification or recapitalization of the Capital Stock or any transfer of all or substantially all of the assets, business, or revenue or income generating capacity of the Company, or consolidation, merger, share exchange, reorganization, or similar transaction involving the Company; or (iii) any voluntary or involuntary dissolution, liquidation, or winding up of the Company; or (iv) any proposed issue, sale or grant by the Company of any Capital Stock, or capital stock or securities of any Subsidiary or any right or option to subscribe for, purchase, or otherwise acquire any Capital Stock or capital stock or securities of any Subsidiary (other than the issue of Permitted Stock and of Issuable Warrant Shares upon exercise of the Warrants), then, in each such event, either prior to or after an Initial Public Offering, as the case may be, the Company will deliver or cause to be delivered to the Holders a notice specifying, as the case may be, (A) the date on which any such record is to be set for the purpose of such dividend, distribution, or right, and stating the amount and character of such dividend, distribution, or right; (B) the date as of which the holders of record will be entitled to vote on any reorganization, reclassification, recapitalization, transfer, consolidation, merger, share exchange, conveyance, dissolution, liquidation, or winding-up; (C) the date on which any such reorganization, reclassification, recapitalization, transfer, consolidation, merger, share exchange, conveyance, dissolution, liquidation, or winding-up is to take place and the time, if any is

Any such notice will be deposited in the United States mail, postage prepaid, at least fifteen (15) days prior to the date therein specified, and notwithstanding anything in this Agreement or the Warrants to the contrary the Holders may exercise the Warrants within fifteen (15) days from the receipt of such notice.

(b) If there is any adjustment as provided above in Article II, the Company will immediately cause written notice thereof to be sent to each Holder, which notice will be accompanied by a certificate of the independent public accountants of the Company setting forth in reasonable detail the basis for the Holders’ becoming entitled to receive such adjustment, the facts requiring any such adjustment and the number of shares receivable after such adjustment. At the request of any Holder and upon surrender of the Warrants of such Holder, the Company will reissue the Warrants of such Holder in a form conforming to such adjustments.

(c) The Company shall provide all Holders with copies of all (a) notices (including notices of default), statements and financial information, including notices of default received by any Subsidiary from the lender under the Senior Loan Agreement and any other creditor or lessor with respect to the acceleration of the maturity of any item of indebtedness for borrowed money or the repossession of property from such Subsidiary, and (b) material information concerning the assets of the Company and all Subsidiaries taken as a whole, including, without limitation, significant contracts, schedules of equipment, changes of equipment or real property.

6.01 Indemnification. In addition to any other rights or remedies to which the Purchasers and the Holders may be entitled, the Company agrees to and will indemnify and hold harmless the Purchasers, the Holders, and their respective successors, assigns, officers, directors, employees, attorneys, and agents (individually and collectively, an “Indemnified Party”) from and against any and all losses, claims, obligations, liabilities, deficiencies, penalties, causes of action, damages, costs, and expenses (including, without limitation, costs of investigation and defense, attorneys’ fees, and expenses), including, without limitation, those arising out of the sole or contributory negligence of any Indemnified Party that the Indemnified Party may suffer, incur, or be responsible for, arising or resulting from any misrepresentation, breach of warranty, or nonfulfillment of any covenant or agreement on the part of the Company under this Agreement, or from any misrepresentation in or omission from any certificate or other instrument furnished or to be furnished to the Purchasers or the Holders under this Agreement. The foregoing indemnification excludes (i) any such claims, actions, damages, costs and expense incurred by reason of the sole or contributory negligence or willful misconduct of the Indemnified Party and (ii) the portion of any loss attributable solely to a decline in the value of any right under the Put Option described in Section 2.10 of this Agreement or a decline in the value of the Warrants or the Warrant Shares.

6.02 Default. It is agreed that a violation by any party of the terms of this Agreement cannot be adequately measured or compensated in money damages, and that any breach or threatened breach of this Agreement by a party to this Agreement would do irreparable injury to the nondefaulting party. It is, therefore, agreed that in the event of any breach or threatened breach by a party to this Agreement of the terms and conditions set forth in this Agreement, the nondefaulting party will be entitled, in addition to any and all other rights and remedies that it may have in law or in equity, to apply for and obtain injunctive relief requiring the defaulting party to be restrained from any such breach or threatened breach or to refrain from a continuation of any actual breach.

If any provision of this Agreement is judicially or administratively interpreted or construed as being in violation of any such policy, rule, regulation, or decision, the provision, section, sentence, word, clause, or combination thereof causing such violation will be inoperative (and in lieu thereof there will be inserted such provision, sentence, word, clause, or combination thereof as may be valid and consistent with the intent of the parties under this Agreement) and the remainder of this Agreement, as amended, will remain binding upon the parties, unless the inoperative provision would cause enforcement of the remainder of this Agreement to be inequitable under the circumstances.
