WARRANT AGREEMENT

          WARRANT AGREEMENT, dated as of March 9, 2000 (the “Agreement”) by and between TRANSPORTATION ACQUISITION I CORP., a Delaware corporation (together with any successor thereto, the “Company”), and First Union National Bank, as warrant agent (“FUNB;” with any successor Warrant Agent, the “Warrant Agent”).

          WHEREAS, the Company has entered into a purchase agreement (the “Purchase Agreement”) dated as of March 9, 2000 by and among the Company, Transportation Technologies Industries, Inc. (“TTII”), a Delaware corporation, the Guarantors named therein, CIBC Inc. (“CIBC”) and First Union Investors Inc. (“FUSI”) (each a “Purchaser” and collectively, the “Purchasers”) in which the Company and TTII have agreed to issue and sell to the Purchasers $125,000,000 aggregate principal amount of Senior Subordinated Increasing Rate Notes due 2008 (the “Notes”) of TTII, along with 198,529 Warrants (the “Warrants”), each Warrant initially entitling the holder thereof to purchase 1.240312 shares of Common Stock, par value $0.01 per share, of the Company (the “Common Stock”) at a price equal to $0.01 per share. Upon the consummation of the merger of the Company with and into TTII, with TTII as the surviving corporation, (the “Merger”), pursuant to the Agreement and Plan of Merger dated as of January 28, 2000 between the Company and TTII, each Warrant will convert into one warrant to purchase 1.240312 shares of common stock of TTII (the “TTII Warrants”). In addition, upon consummation of the Merger, TTII will succeed to all the rights and obligations of the Company under this Agreement, the Warrant Escrow Agreement (as defined herein) and the Registration Rights Agreement (as defined herein) and shall be bound to the same extent as if it were a party hereto and thereto. The certificates evidencing the Warrants are herein referred to collectively as the “Warrant Certificates.” Initially, the Company will deliver the Warrants (the “Escrow Warrants”) to First Union National Bank, as escrow agent (the “Escrow Agent”) pursuant to the terms of the Warrant Escrow Agreement, dated as of March 9, 2000, among the Company, the Purchasers and the Escrow Agent (the “Warrant Escrow Agreement”); and

          WHEREAS, the holders of the Warrants are entitled to the benefits of a Common Stock Registration Rights and Stockholders Agreement dated as of March 9, 2000 between the Company, the Key Equity Group (as defined therein) and the Purchasers (the “Registration Rights Agreement”); and

          WHEREAS, the Company desires the Warrant Agent as warrant agent to assist the Company in connection with the issuance, exchange, cancellation, replacement and exercise of the Warrants, and in this Agreement wishes to set forth, among other things, the terms and conditions on which the Warrants may be issued, exchanged, cancelled, replaced and exercised;

          NOW, THEREFORE, the parties hereto agree as follows:

ARTICLE I

ISSUANCE, FORM, EXECUTION, DELIVERY
AND REGISTRATION OF WARRANT CERTIFICATES

          SECTION 1.01. Issuance of Warrants. Each Warrant Certificate shall evidence the number of Warrants specified therein, and each Warrant evidenced thereby shall, when exercisable as provided herein and therein, represent the right, subject to the provisions contained herein and therein, to purchase from the Company (and the Company shall issue and sell to the holder of such Warrant upon exercise thereof) 1.240312 fully paid and non-assessable shares of the Company’s Common Stock at an exercise price of $0.01 per share. The shares purchasable upon exercise of a Warrant are hereinafter referred to as the “Shares” and are subject to adjustment as provided herein and in the Warrant, and, unless the context otherwise requires, such term shall also include any other securities or property purchasable and deliverable upon exercise of a Warrant as provided in Article V, subject to adjustment as provided herein and in the Warrant.

          SECTION 1.02. Form of Warrant Certificates. The Warrant Certificates will initially be issued either in global form as 144A Global Warrants or Regulation S Global Warrants (collectively, the “Global Warrants”), substantially in the form of Exhibit A hereto, or in registered form as definitive Warrant Certificates (the “Definitive Warrants”) substantially in the form of Exhibit A attached hereto. Any Global Warrants to be delivered pursuant to this Agreement shall bear the legend set forth in Exhibit B attached hereto. Such Global Warrants shall represent such of the outstanding Warrants as shall be specified therein and each shall provide that it shall represent the aggregate amount of outstanding Warrants from time to time endorsed thereon and that the aggregate amount of outstanding Warrants represented thereby may from time to time be reduced or increased, as appropriate. Any endorsement of a Global Warrant to reflect the amount of any increase or decrease in the amount of outstanding Warrants represented thereby shall be made by the Warrant Agent and the Depository (as defined below) in accordance with instructions given by the holder thereof. The Depository Trust Company shall act as the Depository with respect to the Global Warrants, if issued, until a successor shall be appointed by the Company and the Warrant Agent. Upon written request, a holder of record of Warrants may receive from the Warrant Agent or the Depository Definitive Warrants as set forth in Section 1.08 hereof.

          “144A Global Warrant” means a permanent global security in registered form representing the aggregate principal amount of Warrants sold in reliance on Rule 144A.

          “Regulation S Global Warrant” means a permanent global security in registered form representing the aggregate principal amount of Warrants sold in reliance on Regulation S under the Securities Act.

          SECTION 1.03. Execution of Warrant Certificates. The Warrant Certificates shall be executed on behalf of the Company by the chairman of its Board of Directors, its president or any vice president and attested by its secretary or assistant secretary. Such signatures may be the manual or facsimile signatures of the present or any future such officers. Typographical and other minor errors

-2-

or defects in any such reproduction of any such signature shall not affect the validity or enforceability of any Warrant Certificate that has been duly countersigned and delivered by the Warrant Agent.

          In case any officer of the Company who shall have signed any of the Warrant Certificates shall cease to be such officer before the Warrant Certificate so signed shall be countersigned and delivered by the Warrant Agent or disposed of by the Company, such Warrant Certificate nevertheless may be countersigned and delivered or disposed of as though the person who signed such Warrant Certificate had not ceased to be such officer of the Company; and any Warrant Certificate may be signed on behalf of the Company by such persons as, at the actual date of the execution of such Warrant Certificate, shall be the proper officers of the Company, although at the date of the execution and delivery of this Agreement any such person was not such an officer.

          SECTION 1.04. Authentication and Delivery. Subject to the immediately following paragraph, Warrant Certificates shall be authenticated by manual or facsimile signature and dated the date of authentication by the Warrant Agent and shall not be valid for any purpose unless so authenticated and dated. The Warrant Certificates shall be numbered and shall be registered in the Warrant Register (as defined in Section 1.07 hereof).

          Upon the receipt by the Warrant Agent of a written order of the Company, which order shall be signed by the chairman of its Board of Directors, its president, Chief Financial Officer or any vice president and attested by its secretary or assistant secretary, and shall specify the amount of Warrants to be authenticated, whether the Warrants are to be Global Warrants or Definitive Warrants, the date of such Warrants and such other information as the Warrant Agent may reasonably request, without any further action by the Company, the Warrant Agent is authorized, upon receipt from the Company at any time and from time to time of the Warrant Certificates, duly executed as provided in Section 1.03 hereof, to authenticate the Warrant Certificates and upon the holder’s request deliver them. Such authentication shall be by a duly authorized signatory of the Warrant Agent (although it shall not be necessary for the same signatory to sign all Warrant Certificates).

          In case any authorized signatory of the Warrant Agent who shall have authenticated any of the Warrant Certificates shall cease to be such authorized signatory before the Warrant Certificate shall be disposed of by the Company or the Warrant Agent, such Warrant Certificate nevertheless may be delivered or disposed of as though the person who authenticated such Warrant Certificate had not ceased to be such authorized signatory of the Warrant Agent; and any Warrant Certificate may be authenticated on behalf of the Warrant Agent by such persons as, at the actual time of authentication of such Warrant Certificates, shall be the duly authorized signatories of the Warrant Agent, although at the time of the execution and delivery of this Agreement any such person is not such an authorized signatory.

          The Warrant Agent’s authentication on all Warrant Certificates shall be in substantially the form set forth in Exhibit A hereto.

          SECTION 1.05. Temporary Warrant Certificates. Pending the preparation of definitive Warrant Certificates, the Company may execute, and the Warrant Agent shall authenticate and deliver, temporary Warrant Certificates, which are printed, lithographed, typewritten or otherwise

-3-

produced, substantially of the tenor of the definitive Warrant Certificates in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Warrant Certificates may determine, as evidenced by their execution of such Warrant Certificates.

          If temporary Warrant Certificates are issued, the Company will cause definitive Warrant Certificates to be prepared without unreasonable delay. After the preparation of definitive Warrant Certificates, the temporary Warrant Certificates shall be exchangeable for definitive Warrant Certificates upon surrender of the temporary Warrant Certificates at any office or agency maintained by the Company for that purpose pursuant to Section 1.10 hereof. Subject to the provisions of Section 4.01 hereof, such exchange shall be without charge to the holder. Upon surrender for cancellation of any one or more temporary Warrant Certificates, the Company shall execute, and the Warrant Agent shall authenticate and deliver in exchange therefor, one or more definitive Warrant Certificates representing in the aggregate a like number of Warrants. Until so exchanged, the holder of a temporary Warrant Certificate shall in all respects be entitled to the same benefits under this Agreement as a holder of a definitive Warrant Certificate.

          SECTION 1.06. [INTENTIONALLY OMITTED].

          SECTION 1.07. Registration. The Company will keep, at the office or agency maintained by the Company for such purpose, a register or registers in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of, and registration of transfer and exchange of, Warrants as provided in this Article. Each person designated by the Company from time to time as a person authorized to register the transfer and exchange of the Warrants is hereinafter called, individually and collectively, the “Registrar.” The Company hereby initially appoints the Warrant Agent as Registrar. Upon written notice to the Warrant Agent and any acting Registrar, the Company may appoint a successor Registrar for such purposes.

          The Company will at all times designate one person (who may be the Company and who need not be a Registrar) to act as repository of a master list of names and addresses of the holders of Warrants (the “Warrant Register”). The Warrant Agent will act as such repository unless and until some other person is, by written notice from the Company to the Warrant Agent and the Registrar, designated by the Company to act as such. The Company shall cause each Registrar to furnish to such repository, on a current basis, such information as to all registrations of transfer and exchanges effected by such Registrar, as may be necessary to enable such repository to maintain the Warrant Register on as current a basis as is practicable.

          SECTION 1.08. Registration of Transfers or Exchanges.

          (a) Transfer or Exchange of Definitive Warrants. When Definitive Warrants are presented to the Warrant Agent with a request from the holder:

-4-

the Warrant Agent shall register the transfer or make the exchange as requested if the requirements under this Warrant Agreement as set forth in this Section 1.08 hereof for such transactions are met; provided, however, that the Definitive Warrants presented or surrendered by a holder for registration of transfer or exchange:

-5-

          (b) Restrictions on Transfer of a Definitive Warrant for a Beneficial Interest in a Global Warrant. A Definitive Warrant may not be transferred by a holder for a beneficial interest in a Global Warrant except upon satisfaction of the requirements set forth below. Upon receipt by the Warrant Agent of a Definitive Warrant, duly endorsed or accompanied by appropriate instruments of transfer, in form satisfactory to the Warrant Agent, together with:

then the Warrant Agent shall cancel such Definitive Warrant and cause, or direct the Depository to cause, in accordance with the standing instructions and procedures existing between the Depository and the Warrant Agent, the number of Shares represented by the applicable Global Warrant to be increased accordingly. If no ▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ or Regulation S Global Warrant is then outstanding, the Company shall issue and the Warrant Agent shall upon written instructions from the Company authenticate a new Global Warrant in the appropriate amount.

          (c) Transfer or Exchange of Global Warrants. The transfer or exchange of Global Warrants or beneficial interests therein shall be effected through the Depository, in accordance with this Section 1.08, the Private Placement Legend, this Agreement (including the restrictions on transfer set forth herein) and the procedures of the Depository therefor. Upon receipt by the Registrar or Co-Registrar of written instructions, or such other instruction as is customary for the Depository, from the

-6-

Depository or its nominee, requesting the registration of transfer of an interest in a ▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇▇, a Regulation S Global Warrant, as the case may be, to another type of Global Warrant, together with the applicable Global Warrants (or, if the applicable type of Global Warrant required to represent the interest as requested to be obtained is not then outstanding, only the Global Warrant representing the interest being transferred), the Registrar or Co-Registrar shall reflect on its books and records (and the applicable Global Warrant) the applicable increase and decrease of the principal amount of Warrants represented by such types of Global Warrants, giving effect to such transfer. If the applicable type of Global Warrant required to represent the interest as requested to be obtained is not outstanding at the time of such request, the Company shall issue and the Warrant Agent shall, upon written instructions from the Company in accordance with Section 1.08, authenticate a new Global Warrant of such type in principal amount equal to the principal amount of the interest requested to be transferred.

          (d) Transfer or Exchange of a Beneficial Interest in a Global Warrant for a Definitive Warrant.

-7-

          (e) Restrictions on Transfer or Exchange of Global Warrants. Notwithstanding any other provisions of this Agreement (other than the provisions set forth in subsection (f) of this Section 1.08), a Global Warrant may not be transferred or exchanged as a whole except by the Depository to a nominee of the Depository or by a nominee of the Depository to the Depository or another nominee of the Depository or by the Depository or any such nominee to a successor Depository or a nominee of such successor Depository.

          (f) Authentication of Definitive Warrants in Absence of Depository. If at any time:

then the Company will execute, and the Warrant Agent will, upon receipt of an Officers’ Certificate requesting the authentication and delivery of Definitive

-8-

Warrants, authenticate and deliver Definitive Warrants, in an aggregate number equal to the aggregate number of warrants represented by the Global Warrant, in exchange for such Global Warrant.

          (g) Private Placement Legend. Upon the registration of transfer, exchange or replacement of Warrant Certificates not bearing the legend set forth in the first paragraph of Exhibit A attached hereto (the “Private Placement Legend”), the Warrant Agent shall deliver Warrant Certificates that do not bear the Private Placement Legend. Upon the registration of transfer, exchange or replacement of Warrant Certificates bearing the Private Placement Legend, the Warrant Agent shall deliver Warrant Certificates that bear the Private Placement Legend unless, and the Warrant Agent is hereby authorized to deliver Warrant Certificates without the Private Placement Legend if, (i) the requested transfer is not prior to the date which is two years (or such shorter period as may be prescribed by Rule 144(k) (or any successor provision thereto) under the Securities Act or any successor provision thereunder) after the later of the original Issue Date of the Warrants or the last day on which the Company or any of its Affiliates was the owner of the Warrant or any predecessor security, (ii) there is delivered to the Warrant Agent an opinion of counsel reasonably satisfactory to the Company and the Warrant Agent to the effect that neither such legend nor the related restrictions on transfer are required in order to maintain compliance with the provisions of the Securities Act or (iii) the Warrants to be transferred or exchanged represented by such Warrant Certificates are being transferred or exchanged pursuant to an effective registration statement under the Securities Act.

          (h) Cancellation or Adjustment of a Global Warrant. At such time as all beneficial interests in a Global Warrant have either been exchanged for Definitive Warrants, redeemed, repurchased or cancelled, such Global Warrant shall be returned to the Company or, upon written order to the Warrant Agent in the form of an Officers’ Certificate from the Company, retained and cancelled by the Warrant Agent. At any time prior to such cancellation, if any beneficial interest in a Global Warrant is exchanged for Definitive Warrants, redeemed, repurchased or cancelled, the number of Warrants represented by such Global Warrant shall be reduced and an endorsement shall be made on such Global Warrant by the Warrant Agent to reflect such reduction.

          (i) Obligations with Respect to Transfers or Exchanges of Definitive Warrants.

-9-

          “Depository” means, with respect to the Warrants issued in the form of one or more Global Securities, The Depository Trust Company or another Person designated as Depository by the Company, which must be a clearing agency registered under the Exchange Act.

          SECTION 1.09. Lost, Stolen, Destroyed, Defaced or Mutilated Warrant Certificates. Upon receipt by the Company and the Warrant Agent (or any agent of the Company or the Warrant Agent, if requested by the Company) of evidence satisfactory to them of the loss, theft, destruction, defacement, or mutilation of any Warrant Certificate and of an indemnity bond satisfactory to them and, in the case of mutilation or defacement, upon surrender thereof to the Warrant Agent for cancellation, then, in the absence of notice to the Company or the Warrant Agent that such Warrant Certificate has been acquired by a bona fide purchaser or holder in due course, the Company shall execute, and an authorized signatory of the Warrant Agent shall manually authenticate and deliver, in exchange for or in lieu of the lost, stolen, destroyed, defaced or mutilated Warrant Certificate, a new Warrant Certificate representing a like number of Warrants, bearing a number or other distinguishing symbol not contemporaneously outstanding. The Company or the Warrant Agent may require an indemnity bond that is sufficient in the judgment of the Company and the Warrant Agent to protect the Company and the Warrant Agent from any loss which any of them may suffer if a Warrant Certificate is replaced. Upon the issuance of any new Warrant Certificate under this Section in a name other than the prior registered holder of the lost, stolen, destroyed, defaced or mutilated Warrant Certificate, the Company may require the payment from the holder of such Warrant Certificate of a sum sufficient to cover any tax, stamp tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Warrant Agent and the Registrar) in connection therewith. Every substitute Warrant Certificate executed and delivered pursuant to this Section in lieu of any lost, stolen or destroyed Warrant Certificate shall constitute an additional contractual obligation of the Company, whether or not the lost, stolen or destroyed Warrant Certificate shall be at any time enforceable by anyone, and shall be entitled to the benefits of (but shall be subject to all the limitations of rights set forth in) this Agreement equally and proportionately with any and all other Warrant Certificates duly executed and delivered hereunder. The provisions of this Section 1.09 are exclusive with respect to the replacement of lost, stolen, destroyed, defaced or mutilated Warrant Certificates and shall preclude (to the extent lawful) any and all other rights or remedies notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to the replacement of lost, stolen, destroyed, defaced or mutilated Warrant Certificates.

          The Warrant Agent is hereby authorized to authenticate in accordance with the provisions of this Agreement, and deliver the new Warrant Certificates required pursuant to the provisions of this Section.

          SECTION 1.10. Offices for Exercise, etc. So long as any of the Warrants remain outstanding, the Company will designate and maintain in the Borough of Manhattan, The City of New York: (a) an office or agency where the Warrant Certificates may be presented for exercise, (b) an office or agency where the Warrant Certificates may be presented for registration of transfer and for exchange (including the exchange of temporary Warrant Certificates for definitive Warrant Certificates pursuant to Section 1.05 hereof), and (c) an office or agency where notices and demands to or upon the Company in respect of the Warrants or of this Agreement may be served. The Company may from time to time change or rescind such designation, as it may deem desirable or expedient; pro-

-10-

vided, however, that an office or agency shall at all times be maintained in the Borough of Manhattan, The City of New York, as provided in the first sentence of this Section. In addition to such office or offices or agency or agencies, the Company may from time to time designate and maintain one or more additional offices or agencies within or outside The City of New York, where Warrant Certificates may be presented for exercise or for registration of transfer or for exchange, and the Company may from time to time change or rescind such designation, as it may deem desirable or expedient. The Company will give to the Warrant Agent written notice of the location of any such office or agency and of any change of location thereof. The Company hereby designates the Warrant Agent at its corporate trust office identified at ▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇ (the “Warrant Agent Office”), as the initial agency maintained for each such purpose. In case the Company shall fail to maintain any such office or agency or shall fail to give such notice of the location or of any change in the location thereof, presentations and demands may be made and notice may be served at the Warrant Agent Office and the Company appoints the Warrant Agent as its agent to receive all such presentations, surrenders, notices and demands.

          SECTION 1.11. Book-Entry Provisions for Global Warrants. (a) The Global Warrants, if issued, initially shall (i) be registered in the name of the Depository or the nominee of such Depository, (ii) be delivered to the Warrant Agent as custodian for such Depository and (iii) bear legends as set forth in Exhibit B.

          Members of, or participants in, the Depository (“Participants”) shall have no rights under this Warrant Agreement with respect to any Global Warrant held on their behalf by the Depository, or the Warrant Agent as its custodian, or under the Global Warrant, and the Depository may be treated by the Company, the Warrant Agent and any agent of the Company or the Warrant Agent as the absolute owner of the Global Warrant for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Warrant Agent or any agent of the Company or the Warrant Agent from giving effect to any written certification, proxy or other authorization furnished by the Depository or impair, as between the Depository and Participants, the operation of customary practices governing the exercise of the rights of a beneficial owner in a Global Warrant.

          (b) Transfers of Global Warrants shall be limited to transfers in whole, but not in part, to the Depository, its successors or their respective nominees. Interests of beneficial owners in the Global Warrants may be transferred or exchanged for Definitive Warrants in accordance with the rules and procedures of the Depository and the provisions of Section 1.08; provided, however, that Definitive Warrants shall be transferred to all beneficial owners in exchange for their beneficial interests in Global Warrants if (i) the Depository notifies the Company that it is unwilling or unable to continue as Depository for any Global Warrant and a successor Depository is not appointed by the Company within 90 days of such notice, (ii) the Company, at its option, notifies the Warrant Agent in writing that it elects to cause the issuance of the Warrants as Definitive Warrants or (iii) an Event of Default has occurred and is continuing and the Registrar has received a request from the Depository to issue Definitive Warrants.

          (c) In connection with any transfer or exchange of a portion of the beneficial interest in a Global Warrant to beneficial owners pursuant to paragraph (b), the Registrar shall (if one or more Definitive Warrants are to be issued) reflect on its books and records the date and a decrease in the

-11-

principal amount of such Global Warrant in an amount equal to the principal amount of the beneficial interest in the Global Warrant to be transferred, and the Company shall execute, and the Warrant Agent shall authenticate and deliver, one or more Definitive Warrants of like tenor and amount.

          (d) In connection with the transfer of Global Warrants as an entirety to beneficial owners pursuant to paragraph (b) of this Section 1.11, the Global Warrants shall be deemed to be surrendered to the Warrant Agent for cancellation, and the Company shall execute, and the Warrant Agent shall upon written instructions from the Company authenticate and deliver, to each beneficial owner identified by the Depository in exchange for its beneficial interest in the Global Warrants, an equal aggregate principal amount of Definitive Warrants of authorized denominations.

          (e) Any Definitive Warrants constituting a Restricted Security delivered in exchange for an interest in a Global Security pursuant to paragraph (c) of this Section 1.11 shall, except as otherwise provided by Section 1.08, bear the Private Placement Legend.

          (f) The Holder of any Global Warrant may grant proxies and otherwise authorize any Person, including Participants and Persons that may hold interests through Participants, to take any action which a Holder is entitled to take under this Warrant Agreement or the Warrants and the Warrant Agent is entitled to rely upon any electronic instructions from beneficial owners to the Holder of any Global Warrant.

ARTICLE II

DURATION, EXERCISE OF WARRANTS;
EXERCISE PRICE AND REPURCHASE OF WARRANTS

          SECTION 2.01. Duration of Warrants. Subject to the terms and conditions established herein, the Warrants shall expire at 5:00 p.m., New York City time, on March 9, 2010. The applicable date of expiration of a particular Warrant is referred to herein as the “Expiration Date” of such Warrant. Each Warrant may be exercised on any Business Day (as defined below) on or after the Exercisability Date (as defined in Section 2.02) and on or prior to the close of business on the Expiration Date; provided, however, in no event may any Escrow Warrant delivered to the Escrow Agent pursuant to the Purchase Agreement be exercised prior to its release to the Holder thereof pursuant to the terms of the Warrant Escrow Agreement.

          Any Warrant not exercised before the close of business on the Expiration Date shall become void, and all rights of the holder under the Warrant Certificate evidencing such Warrant and under this Agreement shall cease.

          “Business Day” shall mean any day on which (i) banks in New York City, (ii) the principal U.S. securities exchange or market, if any, on which any Common Stock is listed or admitted to trading and (iii) the principal U.S. securities exchange or market, if any, on which the Warrants are listed or admitted to trading are open for business.

-12-

          SECTION 2.02. Exercise, Exercise Price, Settlement and Delivery. (a) Subject to the provisions of this Agreement, a holder of a Warrant shall have the right to purchase from the Company on or after the Exercisability Date and on or prior to the close of business on the Expiration Date the number of fully paid, registered and non-assessable shares of Common Stock specified in Section 1.01, subject to adjustment in accordance with Article V hereof, at the purchase price of $0.01 for each share purchased (the “Exercise Price”). The number of Shares for which a particular Warrant may be exercised (the “Exercise Rate”) shall be subject to adjustment from time to time as set forth in Article V hereof.

          “Exercisability Date” means, with respect to each Warrant, the date of original issuance thereof.

          “Initial Public Equity Offering” means a primary public offering (whether or not underwritten, but excluding any offering pursuant to Form S-4 or Form S-8 under the Securities Act or any other publicly registered offering pursuant to the Securities Act pertaining to an issuance of shares of capital stock of the Company or securities exercisable therefor under any benefit plan, employee compensation plan, or employee or director stock purchase plan) of common stock of the Company pursuant to an effective registration statement under the Securities Act.

          “Registrable Securities” means any of (i) the Common Stock issued and issuable upon exercise of the Warrants and (ii) any other securities issued or issuable with respect to the Warrants or Shares by way of stock dividend or stock split or in connection with a combination of shares, recapitalization, merger, consolidation, reorganization or otherwise. As to any particular Registrable Securities, such securities shall cease to be Registrable Securities when (a) a registration statement with respect to the offering of such securities by the holder thereof shall have been declared effective under the Securities Act and such securities shall have been disposed of by such holder pursuant to such registration statement, (b) such securities have been sold to the public pursuant to, or are eligible for sale to the public without volume or manner of sale restrictions under, Rule 144(k) (or any similar provision then in force, but not Rule 144A) promulgated under the Securities Act, (c) such securities shall have been otherwise transferred and new certificates for such securities not bearing a legend restricting further transfer shall have been delivered by the Company or its transfer agent and subsequent disposition of such securities shall not require registration or qualification under the Securities Act or any similar state law then in force or (d) such securities shall have ceased to be outstanding.

          “Person” means any individual, corporation, partnership, limited liability company, joint venture, association, joint-stock company, trust, unincorporated organization, government or any agency or political subdivision thereof or any other entity, including any predecessor of any such entity.

          (b) Warrants may be exercised on or after the date they are exercisable hereunder by (i) surrendering at any office or agency maintained for that purpose by the Company pursuant to Section 1.10 (each a “Warrant Exercise Office”) the Warrant Certificate evidencing such Warrants with the form of election to exercise Shares set forth on the reverse side of the Warrant Certificate (the “Election to Exercise”) duly completed and signed by the registered holder or holders thereof or by the duly appointed legal representative thereof or by a duly authorized attorney, and in the case of a

-13-

transfer, such signature shall be guaranteed by an eligible guarantor institution, and (ii) paying in full the Exercise Price for each such Warrant exercised. Each Warrant may be exercised only in whole. No exercise of Warrants may be effected which does not call for the issuance of a number of shares of Common Stock in direct proportion (subject only to rounding with respect to fractional shares) to the aggregate number of shares of Common Stock then issuable upon exercise of the Warrants evidenced by the relevant Warrant Certificate.

          (c) Simultaneously with the exercise of each Warrant, payment in full of the aggregate Exercise Price may be made, at the option of the holder, (i) by wire transfer or by certified check, (ii) by the surrender (which surrender shall be evidenced by cancellation of the number of Warrants represented by any Warrant Certificate presented in connection with a Cashless Exercise) of a Warrant or Warrants (represented by one or more Warrant Certificates), and without payment of the Exercise Price in cash, for such number of Shares equal to the product of (1) the number of Shares for which such Warrant is exercisable with payment in cash of the aggregate Exercise Price as of the date of exercise and (2) the applicable Cashless Exercise Ratio or (iii) with any combination of (i) and (ii). For purposes of this Agreement, the “Cashless Exercise Ratio” shall equal a fraction, the numerator of which is the excess of the Current Market Value per share of the Common Stock on the date of exercise over the Exercise Price per share as of the date of exercise and the denominator of which is the Current Market Value per share of the Common Stock on the date of exercise. An exercise of a Warrant in accordance with the immediately preceding sentences is herein called a “Cashless Exercise.” Upon surrender of a Warrant Certificate representing more than one Warrant in connection with the holder’s option to elect a Cashless Exercise, the number of Shares deliverable upon a Cashless Exercise shall be equal to the Cashless Exercise Ratio multiplied by the product of (a) the number of Warrants that the holder specifies is to be exercised pursuant to a Cashless Exercise and (b) the number of Shares for which such Warrant is then exercisable (without giving effect to the Cashless Exercise option). All provisions of this Agreement shall be applicable with respect to an exercise of a Warrant Certificate pursuant to a Cashless Exercise for less than the full number of Warrants represented thereby. No payment or adjustment shall be made on account of any dividends on the Shares issued upon exercise of a Warrant. If the Company has not effected the registration under the Securities Act of the offer and sale of the Shares by the Company to the holders of the Warrants upon the exercise thereof, the Company may elect to require that holders of the Warrants effect the exercise of the Warrants solely pursuant to the Cashless Exercise option and may also amend the Warrants to eliminate the requirement for payment of the Exercise Price with respect such Cashless Exercise option. The Warrant Agent shall have no obligation under this section to calculate the Cashless Exercise Ratio. The Company shall calculate the Exercise Price and the Cashless Exercise Ratio whenever such calculation is necessary and shall deliver an Officers’ Certificate to the Warrant Agent specifying such numbers.

          (d) Upon such surrender of a Warrant Certificate and payment and collection of the Exercise Price at any Warrant Exercise Office (other than any Warrant Exercise Office that also is an office of the Warrant Agent), such Warrant Certificate and payment shall be promptly delivered to the Warrant Agent. The “Exercise Date” for a Warrant shall be the date when all of the items referred to in the first sentence of paragraphs

(b) and (c) of this Section 2.02 are received by the Warrant Agent at or prior to 11:00 a.m., New York City time, on a Business Day and the exercise of the Warrants will be effective as of such Exercise Date. If any items referred to in the first sentence of paragraphs (b) and (c) are received after 11:00 a.m., New York City time, on a Business Day, the exercise of the Warrants to which such item relates will be effective on the next succeeding Business Day. Notwithstanding the foregoing, in the case of an exercise of Warrants on the Expiration Date, if all of the items referred to in the first sentence of paragraphs (b) and (c) are received by the Warrant Agent at or prior to 5:00 p.m., New York City time, on the Expiration Date, the exercise of the Warrants to which such items relate will be effective on the Expiration Date.

          (e) Upon the exercise of a Warrant in accordance with the terms hereof, the receipt of a Warrant Certificate and payment of the Exercise Price (or election of the Cashless Exercise option), the Warrant Agent shall: (i) except to the extent exercise of the Warrant has been effected through Cashless Exercise, cause an amount equal to the aggregate Exercise Price to be paid to the Company by crediting the same to the account designated by the Company in writing to the Warrant Agent for that purpose; (ii) advise the Company immediately by telephone of the amount so deposited to the Company’s account and promptly confirm such telephonic advice in writing; and (iii) as soon as practicable, advise the Company in writing of the number of Warrants exercised in accordance with the terms and conditions of this Agreement and the Warrant Certificates, the instructions of each exercising holder of the Warrant Certificates with respect to delivery of the Shares to which such holder is entitled upon such exercise, and such other information as the Company shall reasonably request.

          (f) Subject to Section 5.02 hereof, as soon as practicable after the exercise of any Warrant or Warrants in accordance with the terms hereof, the Company shall issue or cause to be issued to or upon the written order of the registered holder of the Warrant Certificate evidencing such exercised Warrant or Warrants, a certificate or certificates evidencing the Shares to which such holder is entitled, in fully registered form, registered in such name or names as may be directed by such holder pursuant to the Election to Exercise, as set forth on the reverse of the Warrant Certificate. Such certificate or certificates evidencing the Shares shall be deemed to have been issued and any persons who are designated to be named therein shall be deemed to have become the holder of record of such Shares as of the close of business on the Exercise Date; the Shares may initially be issued in global form (the “Global Shares”). Such Global Shares shall represent such of the outstanding Shares as shall be specified therein and each shall provide that it shall represent the aggregate amount of outstanding Shares from time to time endorsed thereon and that the aggregate amount of outstanding Shares represented thereby may from time to time be reduced or increased, as appropriate. Any endorsement of a Global Share to reflect the amount of any increase or decrease in the amount of outstanding Shares represented thereby shall be made by the registrar for the Shares and the Depository (referred to below) in accordance with instructions given by the holder thereof. The Depository Trust Company shall (if possible) act as the Depository with respect to the Global Shares until a successor shall be appointed by the Company and the registrar for the Shares. After such exercise of any Warrant or Shares, the Company shall also issue or cause to be issued to or upon the written order of the registered holder of such Warrant Certificate, a new Warrant Certificate, countersigned by the Warrant Agent pursuant to written instruction, evidencing the number of Warrants, if any, remaining unexercised unless such Warrants shall have expired.

          SECTION 2.03. Cancellation of Warrant Certificates. In the event the Company shall purchase or otherwise acquire Warrants, the Warrant Certificates evidencing such Warrants may thereupon be delivered to the Warrant Agent, and if so delivered, shall at the Company’s written in-

-15-

struction be canceled by it and retired. The Warrant Agent shall cancel all Warrant Certificates properly surrendered for exchange, substitution, transfer or exercise in accordance with its customary procedures.

ARTICLE III

OTHER PROVISIONS RELATING TO
RIGHTS OF HOLDERS OF WARRANTS

          SECTION 3.01. Enforcement of Rights. (a) Notwithstanding any of the provisions of this Agreement, any holder of any Warrant Certificate, without the consent of the Warrant Agent, the holder of any Shares or the holder of any other Warrant Certificate, may, in and for his own behalf, enforce, and may institute and maintain any suit, action or proceeding against the Company suitable to enforce, his right to exercise the Warrant or Warrants evidenced by his Warrant Certificate in the manner provided in such Warrant Certificate and in this Agreement.

          (b) Neither the Warrants nor any Warrant Certificate shall entitle the holders thereof to any of the rights of a holder of Shares, including, without limitation, the right to vote or to receive any dividends or other payments or to consent or to receive notice as stockholders in respect of the meetings of stockholders or for the election of directors of the Company or any other matter, or any rights whatsoever as stockholders of the Company, except as expressly provided herein (including Section 5.03 hereof).

ARTICLE IV

CERTAIN COVENANTS OF THE COMPANY

          SECTION 4.01. Payment of Taxes. The Company will pay all documentary stamp taxes attributable to the initial issuance of Warrants and of the Shares upon the exercise of Warrants; provided, however, that the Company shall not be required to pay any tax or other governmental charge which may be payable in respect of any transfer or exchange of any Warrant Certificates or any certificates for Shares in a name other than the registered holder of a Warrant Certificate surrendered upon the exercise of a Warrant. In any such case, no transfer or exchange shall be made unless or until the person or persons requesting issuance thereof shall have paid to the Company the amount of such tax or other governmental charge or shall have established to the satisfaction of the Company that such tax or other governmental charge has been paid or an exemption is available therefrom.

          SECTION 4.02. Rules 144 and 144A. The Company covenants that it will file the reports required to be filed by it under the Securities Act and the Exchange Act and the rules and regulations adopted by the Securities and Exchange Commission thereunder in a timely manner in accordance with the requirements of the Securities Act and the Exchange Act and, if at any time the Company is not required to file such reports, it will, upon the request of any holder or beneficial owner of Warrants, make available such information necessary to permit sales pursuant to Rule 144A under the Securities Act.

-16-

          SECTION 4.03. Form of Initial Public Equity Offering. The Company agrees that it will not make an Initial Public Equity Offering of any class of its Capital Stock (other than the class to which the Shares belong) without amending the terms of the Company’s certificate of incorporation to provide that the Common Stock is convertible into the class of Capital Stock subject to the Initial Public Equity Offering (the “Subject Class”) on a share-for-share basis and that the rights, conditions and privileges of the Subject Class shall not be adverse to the holders of the Common Stock.

          SECTION 4.04. Registration of Shares. The Company agrees that it will comply with all applicable laws, including the Securities Act and any applicable state securities laws, in connection with any offer and sale of Common Stock (and other securities and property deliverable) upon exercise of the Warrants.

ARTICLE V

ADJUSTMENTS

          SECTION 5.01. Adjustment of Exercise Rate; Notices. The Exercise Rate and the Exercise Price are subject to adjustment from time to time as provided in this Section.

          (a) Adjustment for Change in Capital Stock. If, after the date hereof, the Company:

        (i) subdivides any of its outstanding shares of Common Stock into a greater number of shares;

        (ii) combines any of its outstanding shares of Common Stock into a smaller number of shares;

        (iii) pays a dividend or makes a distribution on any of its Common Stock in shares of any of its Capital Stock (as defined below) (other than Common Stock or rights, warrants or options for its Common Stock to the extent such issuance or distribution is covered by Section 5.03); or

        (iv) issues by reclassification of any of its Common Stock any shares of any of its Capital Stock;

then the Exercise Rate in effect immediately prior to such action for each Warrant then outstanding shall be proportionately adjusted so that the holder of a Warrant thereafter exercised may receive the number of shares of Capital Stock of the Company which such holder would have owned immediately following such action if such holder had exercised the Warrant immediately prior to such action or immediately prior to the record date applicable thereto and the Exercise Price in effect immediately prior to such action shall be adjusted to a price determined by multiplying the Exercise Price in effect immediately prior to such action by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding before giving effect to such action and the denominator of which shall be the number of shares of Common Stock and/or such other capital stock outstanding referred to in the foregoing clause (a)(iii) after giving effect to such action, if any (regardless of whether the War-

-17-

rants then outstanding are then exercisable and without giving effect to the Cashless Exercise option). If there are no outstanding shares of Common Stock that are of the same class as the Shares at the time of any such action and such action has therefore been taken only in respect of the Shares, the adjustment shall relate to the Shares in their same form if it would not frustrate the intent and purposes of this Section 5.01.

          The adjustment shall become effective immediately after the record date in the case of a dividend or distribution and immediately after the effective date in the case of a subdivision, combination or reclassification. In the event that such dividend or distribution is not so paid or made or such subdivision, combination or reclassification is not effected, the Exercise Rate shall again be adjusted to be the Exercise Rate which would then be in effect if such record date or effective date had not been so fixed.

          If after an adjustment a holder of a Warrant upon exercise of such Warrant may receive shares of two or more classes of Capital Stock of the Company, the Exercise Rate shall thereafter be subject to adjustment upon the occurrence of an action taken with respect to any such class of Capital Stock as is contemplated by this Article V with respect to the Common Stock, on terms comparable to those applicable to Common Stock in this Article V.

          Such adjustment shall be made successively whenever any event listed above shall occur.

          (b) If, after the date hereof, the Company grants or sells to any Affiliate of the Company (other than a wholly-owned subsidiary) any Common Stock or any securities convertible into or exchangeable or exercisable for any Common Stock at a price below the then Current Market Value (other than (1) pursuant to the exercise of the Warrants, (2) pursuant to any security convertible into, or exchangeable or exercisable for shares of Common Stock outstanding as of the date of this Agree ment, (3) upon the conversion, exchange or exercise of any convertible, exchangeable or exercisable security as to which upon the issuance thereof an adjustment pursuant to this Article V has been made and (4) upon the conversion, exchange or exercise of any convertible, exchangeable or exercisable securities of the Company outstanding on the date of this Agreement (to the extent in accordance with the terms of such securities as in effect on the date of this Agreement), the Exercise Rate for each Warrant then outstanding shall be adjusted in accordance with the formula:

and the Exercise Price shall be adjusted in accordance with the following formula:

-18-

where:

          For purposes of this Section 5.01 the term “Fully Diluted Shares” shall mean (i) the shares of Common Stock outstanding as of a specified date, and (ii) the shares of Common Stock into or for which rights, options, warrants or other securities outstanding as of such date are exercisable or convertible (other than the Warrants).

          The adjustments shall be made successively whenever any such rights, options or warrants are issued and shall become effective immediately after the relevant Time of Determination. To the extent that shares of Common Stock are not delivered after the expiration of such rights or warrants, the Exercise Rate for each Warrant then outstanding shall be readjusted to the Exercise Rate which would otherwise be in effect had the adjustment made upon the issuance of such rights or warrants been made on the basis of delivery of only the number of shares of Common Stock actually delivered. In the event that such rights or warrants are not so issued, the Exercise Rate for each Warrant then outstanding shall again be adjusted to be the Exercise Rate which would then be in effect if such date fixed for determination of stockholders entitled to receive such rights or warrants had not been so fixed.

          No adjustment shall be made under this paragraph (b) if the application of the formula stated above in this paragraph (b) would result in a value of E’ that is lower than the value of E.

          No adjustment in the Exercise Rate shall be made under this paragraph (b) upon the conversion, exchange or exercise of options to acquire shares of Common Stock by officers, directors,

-19-

employees or consultants of the Company; provided that the exercise price of such options, at the time of issuance thereof, is at least equal to the then Current Market Value of the Common Stock underlying such options.

          “Affiliate” of any specified Person means any other Person which, directly or indirectly, controls, is controlled by or is under direct or indirect common control with such specified Person. For purposes of this definition, “control” (including, with correlative meanings, the terms “controlling,” “controlled by” and “under common control with”) when used with respect to any Person means the power to direct the management and policies of such Person, directly or indirectly, whether through the ownership of voting securities, by contract or otherwise.

          (c) Reorganization of Company; Special Distributions. (i) If the Company, in a single transaction or through a series of related transactions, merges, consolidates or amalgamates with or into any other person or sells, assigns, transfers, leases, conveys or otherwise disposes of all or substantially all of its properties and assets to another person or group of affiliated persons or is a party to a merger or binding share exchange which reclassifies or changes its outstanding Common Stock (a “Fundamental Transaction”), as a condition to consummating any such transaction the person formed by or surviving any such consolidation or merger if other than the Company or the person to whom such transfer has been made (the “Surviving Person”) shall enter into a supplemental warrant agreement. The supplemental warrant agreement shall provide that the holder of a Warrant then outstanding may exercise it for the kind and amount of securities, cash or other assets which such holder would have received immediately after the Fundamental Transaction if such holder had exercised the Warrant immediately before the effective date of the transaction (regardless of whether the Warrants are then exercisable and without giving effect to the Cashless Exercise option), assuming (to the extent applicable) that such holder (i) was not a constituent person or an affiliate of a constituent person to such transaction, (ii) made no election with respect thereto, and (iii) was treated alike with the plurality of non-electing holders.

          (ii) Notwithstanding the foregoing, if the Company enters into a Fundamental Transaction with another Person (other than a subsidiary of the Company) and consideration is payable to holders of shares of Capital Stock (or other securities or property) issuable or deliverable upon exercise of the Warrants that are exercisable in exchange for their shares in connection with such Fundamental Transaction which consists solely of cash, then the holders of Warrants shall be entitled to receive distributions on the date of such event on an equal basis with holders of such shares (or other securities issuable upon exercise of the Warrants) as if the Warrants had been exercised immediately prior to such event, less the Exercise Price therefor. Upon receipt of such payment, if any, the rights of a holder of such a Warrant shall terminate and cease and such holder’s Warrants shall expire.

          (iii) If this paragraph (c) applies, it shall supersede the application of paragraph (a) of this Section 5.01.

          (d) Notice of Adjustment. Whenever the Exercise Rate or Exercise Price is adjusted, the Company shall promptly mail to holders of Warrants then outstanding at the addresses appearing on the Warrant Register a notice of the adjustment. The Company shall file with the Warrant Agent and any other Registrar such notice and a certificate from the Company’s independent public account-

-20-

ants briefly stating the facts requiring the adjustment and the manner of computing it. The certificate shall be conclusive evidence that the adjustment is correct. Neither the Warrant Agent nor any such Registrar shall be under any duty or responsibility with respect to any such certificate except to exhibit the same during normal business hours to any holder desiring inspection thereof.

          (e) Company Determination Final. Any determination that the Company or the Board of Directors of the Company must make pursuant to this Section 5.01 is conclusive.

          (f) Warrant Agent’s Adjustment Disclaimer. The Warrant Agent has no duty to determine when an adjustment under this Section 5.01 should be made, how it should be made or what it should be. The Warrant Agent has no duty to determine whether a supplemental warrant agreement under paragraph (e) need be entered into or whether any provisions of any supplemental warrant agreement are correct. The Warrant Agent shall not be accountable for and makes no representation as to the validity or value of any securities or assets issued upon exercise of Warrants. The Warrant Agent shall not be responsible for the Company’s failure to comply with this Section 5.01.

          (g) Adjustment for Tax Purposes. The Company may make such increases in the Exercise Rate, in addition to those otherwise required by this Section, as it considers to be advisable in order that any event treated for Federal income tax purposes as a dividend of stock or stock rights shall not be taxable to the recipients.

          (h) Underlying Shares. The Company shall at all times reserve and keep available, free from preemptive rights, out of its authorized but unissued Common Stock or Common Stock held in the treasury of the Company, for the purpose of effecting the exercise of Warrants, the full number of Shares then deliverable upon the exercise of all Warrants then outstanding and payment of the exercise price, and the shares so deliverable shall be fully paid and nonassessable and free from all liens and security interests.

          (i) Specificity of Adjustment. Irrespective of any adjustments in the number or kind of shares purchasable upon the exercise of the Warrants, Warrant Certificates theretofore or thereafter issued may continue to express the same number and kind of Shares per Warrant as are stated on the Warrant Certificates initially issuable pursuant to this Agreement.

          (j) Voluntary Adjustment. The Company from time to time may increase the Exercise Rate or reduce the Exercise Price by any number and for any period of time (provided that such period is not less than 20 Business Days). Whenever the Exercise Rate is so increased or the Exercise Price so reduced, the Company shall mail to holders at the addresses appearing on the Warrant Register and file with the Warrant Agent a notice of the increase. The Company shall give the notice at least 15 days before the date the increased Exercise Rate or decreased Exercise Price takes effect. The notice shall state the increased Exercise Rate or decreased Exercise Price and the period it will be in effect. A voluntary increase in the Exercise Rate or decrease in the Exercise Price does not change or adjust the Exercise Rate or Exercise Price otherwise in effect as determined by this Section 5.01.

          (k) Multiple Adjustments. After an adjustment to the Exercise Rate or Exercise Price for outstanding Warrants under this Article V, any subsequent event requiring an adjustment

-21-

under this Article V shall cause an adjustment to the Exercise Rate or Exercise Price for outstanding Warrants as so adjusted.

          (l) Minimum Exercise Price. Notwithstanding anything to the contrary contained in this Agreement, if the Exercise Price, as adjusted pursuant to this Agreement (other than this Section 5.01(l)), shall be less than the par value of the related Share, then such Exercise Price, as so adjusted, for all purposes of this Agreement, shall be an amount equal to the par value of such related Shares.

          (m) Definitions.

          “Capital Stock” means, with respect to any person, any and all shares, interests, participations, rights in, or other equivalents (however designated and whether voting or non-voting) of, such person’s capital stock, whether outstanding on the Issue Date (as defined in the Indenture) or issued after the Issue Date, and any and all rights, warrants or options exchangeable for or convertible into such capital stock.

          “Current Market Value” per share of Common Stock of the Company or any other security at any date means (i) if the security is not registered under the Exchange Act, the fair market value of the security, determined by an Independent Financial Expert or (ii) (a) if the security is registered under the Exchange Act, the average of the daily closing sales prices of the securities for the 20 consecutive days immediately preceding such date, or (b) if the security has been registered under the Exchange Act for less than 20 consecutive trading days immediately preceding such date, then the offering price of the security in the transaction causing registration under the Exchange Act, in the case of each of (ii)(a) and (ii)(b), as certified to the Warrant Agent by the President, any Vice President or the Chief Financial Officer of the Company. The closing sales price for each such trading day shall be: (A) in the case of a security listed or admitted to trading on any United States national securities exchange or quotation system, the closing sales price, regular way, on such day, or if no sale takes place on such day, the average of the closing bid and asked prices on such day, (B) in the case of a security not then listed or admitted to trading on any United States national securities exchange or quotation system, the last reported sale price on such day, or if no sale takes place on such day, the average of the closing bid and asked prices on such day, as reported by a reputable quotation source designated by the Company, (C) in the case of a security not then listed or admitted to trading on any United States national securities exchange or quotation system and as to which no such reported sale price or bid and asked prices are available, the average of the reported high bid and low asked prices on such day, as reported by a reputable quotation service, or a newspaper of general circulation in the Borough of Manhattan, City and State of New York customarily published on each Business Day, designated by the Company, or, if there shall be no bid and asked prices on such day, the average of the high bid and low asked prices, as so reported, on the most recent day (not more than 30 days prior to the date in question) for which prices have been so reported and (D) if there are not bid and asked prices reported during the 30 days prior to the date in question, the Current Market Value shall be determined by the Board of Directors of the Company or an Independent Financial Expert.

          “Independent Financial Expert” means a United States investment banking firm of national or regional standing in the United States (i) which does not, and whose directors, officers and

-22-

employees or Affiliates do not have a direct or indirect material financial interest for its proprietary account in the Company or any of its Affiliates and (ii) which, in the judgment of the Board of Directors of the Company, is otherwise independent with respect to the Company and its Affiliates and qualified to perform the task for which it is to be engaged.

          (n) When De Minimis Adjustment May Be Deferred. No adjustment in the Exercise Rate or Exercise Price need be made unless the adjustment would require an increase of at least 1% in the Exercise Rate. Any adjustments that are not made shall be carried forward and taken into account in any subsequent adjustments. All calculations under this Section 5.01 shall be made to the nearest 1/100th of a share, as the case may be.

          SECTION 5.02. Fractional Shares. The Company will not be required to issue fractional Shares upon exercise of the Warrants or distribute Share certificates that evidence fractional Shares. In the event a holder is required by Section 2.02(c) to make a Cashless Exercise, and the Company determines not to issue fractional Shares, the number of Shares issuable shall be rounded up to the nearest whole number. In addition, in no event shall any holder of Warrants be required to make any payment of a fractional cent. In lieu of fractional Shares, the Company may pay to the registered holders of Warrant Certificates at the time Warrants evidenced thereby are exercised as herein provided an amount in cash equal to the same fraction of the Current Market Value, per Share on the Business Day preceding the date the Warrant Certificates evidencing such Warrants are surrendered for exercise. Such payments will be made by check or by transfer to an account maintained by such registered holder with a bank in The City of New York. If any holder surrenders for exercise more than one Warrant Certificate, the number of Shares deliverable to such holder may, at the option of the Company, be computed on the basis of the aggregate amount of all the Warrants exercised by such holder.

          SECTION 5.03. Certain Distributions. If at any time the Company grants, issues or sells options, convertible securities, or rights to purchase Capital Stock, warrants or other securities pro rata to the record holders of any Common Stock (the “Distribution Rights”) or, without duplication, makes any dividend or otherwise makes any distribution, including, subject to applicable law, pursuant to any plan of liquidation (“Distribution”) on Common Stock (whether in cash, property, evidences of indebtedness or otherwise), then the Company shall grant, issue, sell or make to each registered holder of Warrants then outstanding, the aggregate Distribution Rights or Distribution, as the case may be, which such holder would have acquired if such holder had held the maximum number of Shares acquirable upon complete exercise of such holder’s Warrants (regardless of whether the Warrants are then exercisable and without giving effect to the Cashless Exercise option) immediately before the record date for the grant, issuance or sale of such Distribution Rights or Distribution, as the case may be, or, if there is no such record date, the date as of which the record holders of Common Stock are to be determined for the grant, issue or sale of such Distribution Rights or Distribution, as the case may be.

Such application by the Warrant Agent for written instructions from the Company may, at the option of the Warrant Agent, set forth in writing any action proposed to be taken or omitted by the Warrant Agent with respect to its duties or obligations under this Agreement and the date on or after which such action shall be taken and the Warrant Agent shall not be liable for any action taken or omitted in accordance with a proposal included in any such application on or after the date specified therein (which date shall be not less than 10 Business Days after the Company receives such application unless the Company consents to a shorter period), provided that (i) such application includes a statement to the effect that it is being made pursuant to this paragraph (n) and that unless objected to prior to such date specified in the application, the Warrant Agent will not be liable for any such action or omission to the extent set forth in such paragraph (n) and (ii) prior to taking or omitting any such action, the Warrant Agent has not received written instructions objecting to such proposed action or omission.

          (o) Whenever in the performance of its duties under this Agreement the Warrant Agent shall deem it necessary or desirable that any fact or matter be proved or established by the Company prior to taking or suffering any action hereunder, such fact or matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed to be conclusively proved and established by a certificate signed on behalf of the Company by any one of the chairman of the Board of Directors, the president, the treasurer, the controller, any vice president or the secretary or assistant secretary of the Company or any other officer or official of the Company reasonably believed to be authorized to give such instructions and delivered to the Warrant Agent; and such certificate shall be full authorization to the Warrant Agent for any action taken or suffered in good faith by it under the provisions of this Agreement in reliance upon such certificate.

          (p) The Warrant Agent shall not be required to risk or expend its own funds in the performance of its obligations and duties hereunder.

          SECTION 6.03. Resignation and Appointment of Successor. (a) The Company agrees, for the benefit of the holders from time to time of the Warrant Certificates, that there shall at all times be a Warrant Agent hereunder.

-27-

          (b) The Warrant Agent may at any time resign as Warrant Agent by giving written notice to the Company of such intention on its part, specifying the date on which its desired resignation shall become effective; provided, however, that such date shall be at least 30 days after the date on which such notice is given unless the Company agrees to accept less notice. Upon receiving such notice of resignation, the Company shall promptly appoint a successor Warrant Agent, qualified as provided in Section 6.03(d) hereof, by written instrument in duplicate signed on behalf of the Company, one copy of which shall be delivered to the resigning Warrant Agent and one copy to the successor Warrant Agent. As provided in Section 6.03(d) hereof, such resignation shall become effective upon the earlier of (x) the acceptance of the appointment by the successor Warrant Agent or (y) 30 days after receipt by the Company of notice of such resignation. The Company may, at any time and for any reason, and shall, upon any event set forth in the next succeeding sentence, remove the Warrant Agent and appoint a successor Warrant Agent by written instrument in duplicate, specifying such removal and the date on which it is intended to become effective, signed on behalf of the Company, one copy of which shall be delivered to the Warrant Agent being removed and one copy to the successor Warrant Agent. The Warrant Agent shall be removed as aforesaid if it shall become incapable of acting, or shall be adjudged a bankrupt or insolvent, or a receiver of the Warrant Agent or of its property shall be appointed, or any public officer shall take charge or control of it or of its property or affairs for the purpose of rehabilitation, conservation or liquidation. Any removal of the Warrant Agent and any appointment of a successor Warrant Agent shall become effective upon acceptance of appointment by the successor Warrant Agent as provided in Section 6.03(d). As soon as practicable after appointment of the successor Warrant Agent, the Company shall cause written notice of the change in the Warrant Agent to be given to each of the registered holders of the Warrants in the manner provided for in Section 8.04 hereof.

          (c) Upon resignation or removal of the Warrant Agent, if the Company shall fail to appoint a successor Warrant Agent within a period of 60 days after receipt of such notice of resignation or removal, then the holder of any Warrant Certificate or the retiring Warrant Agent may apply to a court of competent jurisdiction for the appointment of a successor to the Warrant Agent. Pending appointment of a successor to the Warrant Agent, either by the Company or by such a court, the duties of the Warrant Agent shall be carried out by the Company.

          (d) Any successor Warrant Agent, whether appointed by the Company or by a court, shall be a bank or trust company in good standing, incorporated under the laws of the United States of America or any State thereof and having, at the time of its appointment, a combined capital surplus of at least $250 million. Such successor Warrant Agent shall execute and deliver to its predecessor and to the Company an instrument accepting such appointment hereunder and all the provisions of this Agreement, and thereupon such successor Warrant Agent, without any further act, deed or conveyance, shall become vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like effect as if originally named as Warrant Agent hereunder, and such predecessor shall thereupon become obligated to (i) transfer and deliver, and such successor Warrant Agent shall be entitled to receive, all securities, records or other property on deposit with or held by such predecessor as Warrant Agent hereunder and (ii) upon payment of the amounts then due it pursuant to Section 6.02(a) hereof, pay over, and such successor Warrant Agent shall be entitled to receive, all monies deposited with or held by any predecessor Warrant Agent hereunder.

-28-

          (e) Any corporation or bank into which the Warrant Agent hereunder may be merged or converted, or any corporation or bank with which the Warrant Agent may be consolidated, or any corporation or bank resulting from any merger, conversion or consolidation to which the Warrant Agent shall be a party, or any corporation or bank to which the Warrant Agent shall sell or otherwise transfer all or substantially all of its corporate trust business, shall be the successor to the Warrant Agent under this Agreement (provided that such corporation or bank shall be qualified as aforesaid) without the execution or filing of any document or any further act on the part of any of the parties hereto.

          (f) No Warrant Agent under this Warrant Agreement shall be personally liable for any action or omission of any successor Warrant Agent.

No. [  ] [     ] Warrants

WARRANT CERTIFICATE

TRANSPORTATION ACQUISITION I CORP.

          This Warrant Certificate certifies that [       ], or registered assigns, is the registered holder of [    ] Warrants (the “Warrants”) to purchase shares of Common Stock, par value $0.01 per share (the “Common Stock”), of TRANSPORTATION ACQUISITION I CORP., a Delaware corporation (the “Company”, which term includes its successors and assigns). Each Warrant entitles the holder to purchase from the Company at any time from 9:00 a.m. New York City time on or after the Exercisability Date until 5:00 p.m., New York City time, on March 9, 2010 (the “Expiration Date”) (provided, however, in no event may any Escrow Warrant delivered to the Escrow Agent pursuant to the Purchase Agreement be exercised prior to its release to the Holder thereof pursuant to the terms of the Warrant Escrow Agreement), 1.240312 fully paid, registered and non-assessable shares of Common Stock, subject to adjustment as provided in Article V of the Warrant Agreement, at the exercise price of $0.01 for each share purchased (the “Exercise Price”), subject to adjustment as provided in Article V of the Warrant Agreement (the shares of Common Stock purchasable upon exercise of a Warrant being herein referred to as the “Shares” and, unless the context otherwise requires, such term shall also mean the other securities or property purchasable and deliverable upon exercise of a Warrant as provided in the Warrant Agreement), upon surrender of this Warrant Certificate and payment of the Exercise Price (i) by wire transfer or certified check, (ii) pursuant to the next sentence or (iii) in any combination of (i) and (ii), at any office or agency maintained for that purpose by the Company (the “Warrant Agent Office”), subject to the conditions set forth herein and in the Warrant Agreement. A Warrant may also be exercised solely by the surrender of the Warrant, and without the payment of the Exercise Price in cash, for such number of Shares equal to the product of (1) the number of Shares for which such Warrant is exercisable with payment of the Exercise Price as of the date of exercise and (2) the Cashless Exercise Ratio. For purposes of this Warrant, the “Cashless Exercise Ratio” shall equal a fraction, the numerator of which is the excess of the Current Market Value per share of the Common Stock on the date of exercise over the Exercise Price per share as of the date of exercise and the denominator of which is the Current Market Value per share of the Common Stock on the date of exercise. An exercise of a Warrant in accordance with the immediately preceding sentences is herein called a “Cashless Exercise.” Upon surrender of a Warrant Certificate representing more than one Warrant in connection with the Holder’s option to elect a Cashless Exercise, the number of Shares deliverable upon a Cashless Exercise shall be equal to the Cashless Exercise Ratio multiplied by the product of (a) the number of Warrants that the holder specifies is to be exercised pursuant to a Cashless Exercise and (b) the number of Shares for which such Warrant is then exercisable (without giving effect to the Cashless Exercise Option). If the Company has not effected the registration under the Securities Act of the offer and sale of the Shares by the Company to the holders of the Warrants upon the exercise thereof, the Company may elect to require that holders of the Warrants effect the exercise of the Warrants solely pursuant to the Cashless Exercise option and may also amend the Warrants to eliminate the requirement for payment of the Exercise Price with respect to such Cashless Exercise option. All provisions of the Warrant Agreement shall be applicable with respect to an exercise of a Warrant Certificate pursuant to a Cashless Exercise for less than the full number of Warrants represented thereby. Capitalized terms used herein without being defined herein shall have the definitions ascribed to such terms in the Warrant Agreement.

A-3

          “Current Market Value” per share of Common Stock of the Company or any other security at any date means (i) if the security is not registered under the Exchange Act, the fair market value of the security, determined by an Independent Financial Expert or (ii) (a) if the security is registered under the Exchange Act, the average of the daily closing sales prices of the securities for the 20 consecutive days immediately preceding such date, or (b) if the security has been registered under the Exchange Act for less than 20 consecutive trading days before such date, then the offering price of the security in the transaction causing registration under the Exchange Act, in the case of each of (ii)(a) and (ii)(b), as certified to the Warrant Agent by the President, any Vice President or the Chief Financial Officer of the Company. The closing sales price for each such trading day shall be: (A) in the case of a security listed or admitted to trading on any United States national securities exchange or quotation system, the closing sales price, regular way, on such day, or if no sale takes place on such day, the average of the closing bid and asked prices on such day, (B) in the case of a security not then listed or admitted to trading on any United States national securities exchange or quotation system, the last reported sale price on such day, or if no sale takes place on such day, the average of the closing bid and asked prices on such day, as reported by a reputable quotation source designated by the Company, (C) in the case of a security not then listed or admitted to trading on any United States national securities exchange or quotation system and as to which no such reported sale price or bid and asked prices are available, the average of the reported high bid and low asked prices on such day, as reported by a reputable quotation service, or a newspaper of general circulation in the Borough of Manhattan, City and State of New York customarily published on each Business Day, designated by the Company, or, if there shall be no bid and asked prices on such day, the average of the high bid and low asked prices, as so reported, on the most recent day (not more than 30 days prior to the date in question) for which prices have been so reported and (D) if there are not bid and asked prices reported during the 30 days prior to the date in question, the Current Market Value shall be determined by the Board of Directors of the Company or an Independent Financial Expert.

          “Exercisability Date” means, with respect to each Warrant, the date of original issuance thereof.

          “Independent Financial Expert” means a United States investment banking firm of national or regional standing, (i) which does not, and whose directors, officers and employees or Affiliates do not have a direct or indirect material financial interest for its proprietary account in the Company or any of its Affiliates and (ii) which, in the judgment of the Board of Directors of the Company, is otherwise independent with respect to the Company and its Affiliates and qualified to perform the task for which it is to be engaged.

          No exercise of the Warrants may be effected which does not call for the issuance of a number of shares of Common Stock in direct proportion (subject only to rounding with respect to fractional shares) to the aggregate number of shares of Common Stock then issuable upon exercise of the Warrants evidenced hereby.

          The Company has initially designated the principal corporate trust office of the Warrant Agent in the Borough of Manhattan, The City of New York, as the initial Warrant Agent Office. The number of Shares issuable upon exercise of the Warrants (“Exercise Rate”) is subject to adjustment upon the occurrence of certain events set forth in the Warrant Agreement.

          Any Warrants not exercised on or prior to 5:00 p.m., New York City time, on March 9, 2010 shall thereafter be void.

A-4

          If the Company merges, amalgamates or consolidates with or into, or sells all or substantially all of its property and assets to, another Person solely for cash, the holders of Warrants shall be entitled to receive distributions on the date of such event on an equal basis with holders of Shares (or other securities issuable upon exercise of the Warrants) as if the Warrants had been exercised immediately prior to such event (less the Exercise Price).

          Reference is hereby made to the further provisions on the reverse hereof which provisions shall for all purposes have the same effect as though fully set forth at this place.

          This Warrant Certificate shall not be valid unless authenticated by the Warrant Agent, as such term is used in the Warrant Agreement.

          THIS WARRANT CERTIFICATE SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT GIVING EFFECT TO THE CONFLICT OF LAWS PROVISIONS THEREOF.

TRANSPORTATION ACQUISITION I CORP.

          The Warrants evidenced by this Warrant Certificate are part of a duly authorized issue of Warrants expiring at 5:00 p.m., New York City time, on March 9, 2010 (the “Expiration Date”), each of which represents the right to purchase at any time on or after the Exercisability Date (as defined in the Warrant Agreement) and on or prior to the Expiration Date 1.240312 shares of Common Stock, subject to adjustment as set forth in the Warrant Agreement. The Warrants are issued pursuant to a Warrant Agreement dated as of March 9, 2000 (the “Warrant Agreement”), duly executed and delivered by the Company to First Union National Bank, as Warrant Agent (the “Warrant Agent”), which Warrant Agreement is hereby incorporated by reference in and made a part of this instrument and is hereby referred to for a description of the rights, limitation of rights, obligations, duties and immunities thereunder of the Warrant Agent, the Company and the holders (the words “holders” or holder” meaning the registered holders or registered holder) of the Warrants.

          Warrants may be exercised by (i) surrendering at any Warrant Agent Office this Warrant Certificate with the form of Election to Exercise set forth hereon duly completed and executed and (ii) to the extent such exercise is not being effected through a Cashless Exercise by paying in full the Warrant Exercise Price for each such Warrant exercised and any other amounts required to be paid pursuant to the Warrant Agreement.

          If all of the items referred to in the preceding paragraph are received by the Warrant Agent at or prior to 11:00 a.m., New York City time, on a Business Day, the exercise of the Warrant to which such items relate will be effective on such Business Day. If any items referred to in the preceding paragraph are received after 11:00 a.m., New York City time, on a Business Day, the exercise of the Warrants to which such item relates will be deemed to be effective on the next succeeding Business Day. Notwithstanding the foregoing, in the case of an exercise of Warrants on March 9, 2010, if all of the items referred to in the preceding paragraph are received by the Warrant Agent at or prior to 5:00 p.m., New York City time, on such Expiration Date, the exercise of the Warrants to which such items relate will be effective on the Expiration Date.

          As soon as practicable after the exercise of any Warrant or Warrants, the Company shall issue or cause to be issued to or upon the written order of the registered holder of this Warrant Certificate, a certificate or certificates evidencing the Share or Shares to which such holder is entitled, in fully registered form, registered in such name or names as may be directed by such holder pursuant to the Election to Exercise, as set forth on the reverse of this Warrant Certificate. Such certificate or certificates evidencing the Share or Shares shall be deemed to have been issued and any persons who are designated to be named therein shall be deemed to have become the holder of record of such Share or Shares as of the close of business on the date upon which the exercise of this Warrant was deemed to be effective as provided in the preceding paragraph.

          The Company will not be required to issue fractional shares of Common Stock upon exercise of the Warrants or distribute Share certificates that evidence fractional shares of Common Stock. In lieu of fractional shares of Common Stock, the Company may pay to the registered Holder

A-8

of this Warrant Certificate at the time such Warrant Certificate is exercised an amount in cash equal to the same fraction of the Current Market Value per share of Common Stock on the Business Day preceding the date this Warrant Certificate is surrendered for exercise.

          Warrant Certificates, when surrendered at any office or agency maintained by the Company for that purpose by the registered holder thereof in person or by legal representative or attorney duly authorized in writing, may be exchanged for a new Warrant Certificate or new Warrant Certificates evidencing in the aggregate a like number of Warrants, in the manner and subject to the limitations provided in the Warrant Agreement, without charge except for any tax or other governmental charge imposed in connection therewith.

          Upon due presentment for registration of transfer of this Warrant Certificate at any office or agency maintained by the Company for that purpose, a new Warrant Certificate evidencing in the aggregate a like number of Warrants shall be issued to the transferee in exchange for this Warrant Certificate, subject to the limitations provided in the Warrant Agreement, without charge except for any tax or other governmental charge imposed in connection therewith.

          The Company and the Warrant Agent may deem and treat the registered holder hereof as the absolute owner of this Warrant Certificate (notwithstanding any notation of ownership or other writing hereon made by anyone) for the purpose of any exercise hereof and for all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary.

          The term “Business Day” shall mean any day on which (i) banks in New York City, (ii) the principal U.S. securities exchange or market, if any, on which the Common Stock is listed or admitted to trading and (iii) the principal U.S. securities exchange or market, if any, on which the Warrants are listed or admitted to trading are open for business.

          The Warrants and the Shares are entitled to the benefits of a registration rights agreement relating to the Warrants and the shares of Common Stock issuable upon exercise thereof (the “Registration Rights Agreement”). The Common Stock Registration Rights Agreement provides the holders of Registrable Securities with the right, subject to the conditions and limitations contained therein, to include the Registrable Securities in certain registration statements filed by the Company for its account or for the account of any of its securityholders.

          4. We understand that, on any proposed resale of Warrants, we will be required to furnish to the Warrant Agent and the Company, such certification, legal opinions and other information as the Warrant Agent and the Company may reasonably require to confirm that the proposed sale complies with the foregoing restrictions. We further understand that the Warrants purchased by us will bear a legend to the foregoing effect.

          5. We are an institutional “accredited investor” (as defined in Rule 501(a)(1), (2), (3) or (7) of Regulation D under the Securities Act) and have such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of our investment in the Warrants, and we and any accounts for which we are acting are each able to bear the economic risk of our or their investment, as the case may be.
