WARRANTS

Section 2.01. Form.

(a) Global Warrants. Except as provided in Section 2.04 or 2.05, Warrants issued upon any transfer or exchange thereof shall be issued in the form of one or more permanent global Warrants in fully registered form with the global securities legend set forth in Exhibit A

hereto (each, a “Global Warrant”), which shall be deposited on behalf of the Company with the Warrant Agent, as custodian for the Depositary (or with such other custodian as the Depositary may direct), and registered in the name of the Depositary or a nominee of the Depositary, duly executed by the Company and countersigned by the Warrant Agent as hereinafter provided.

(b) Book-Entry Provisions. This Section 2.01(b) shall apply only to a Global Warrant deposited with or on behalf of the Depositary.

(i) The Company shall execute and the Warrant Agent shall, in accordance with Section 2.02, countersign, by either manual or facsimile signature, and deliver one or more Global Warrants that (A) shall be registered in the name of the Depositary or the nominee of the Depositary and (B) shall be delivered by the Warrant Agent to the Depositary or pursuant to the Depositary’s instructions or held by the Warrant Agent as custodian for the Depositary. Each Global Warrant shall be dated the date of its countersignature by the Warrant Agent.

(ii) Agent Members shall have no rights under this Agreement with respect to any Global Warrant held on their behalf by the Depositary or by the Warrant Agent as the custodian of the Depositary or under such Global Warrant except to the extent set forth herein or in a Warrant Certificate, and the Depositary may be treated by the Company, the Warrant Agent and any agent of the Company or the Warrant Agent as the absolute owner of such Global Warrant for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall (A) 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 Depositary or (B) impair, as between the Depositary and the Agent Members, the operation of customary practices of the Depositary governing the exercise of the rights of a holder of a beneficial interest in any Warrant. The rights of beneficial owners in a Global Warrant shall be exercised through the Depositary subject to the applicable procedures of the Depositary except to the extent set forth herein or in a Warrant Certificate.

(c) Definitive Securities. Except as provided in Section 2.04 or 2.05, owners of beneficial interests in Global Warrants will not be entitled to receive physical delivery of Definitive Warrants.

(d) Warrant Certificates. Warrant Certificates shall be in substantially the form attached as Exhibit A hereto and shall be typed, printed, lithographed or engraved or produced by any combination of such methods or produced in any other manner permitted by the rules of any securities exchange on which the Warrants may be listed, all as determined by the Officer or Officers executing such Warrant Certificates, as evidenced by their execution thereof. Any Warrant Certificate shall have such insertions as are appropriate or required or permitted by this Agreement and may have such letters, numbers or other marks of identification and such legends and endorsements, stamped, printed, lithographed or engraved thereon, (i) as the Company may deem appropriate and as are not inconsistent with the provisions of this Agreement, (ii) such as may be required to comply with this Agreement, any applicable law or any rule of any securities

exchange on which the Warrants may be listed, and (iii) such as may be necessary to conform to customary usage.

Section 2.02. Execution and Countersignature.

At least one Officer shall sign the Warrant Certificates for the Company by manual or facsimile signature.

If an Officer whose signature is on a Warrant Certificate no longer holds that office at the time the Warrant Agent countersigns the Warrant Certificate, the Warrants evidenced by such Warrant Certificate shall be valid nevertheless.

The Warrant Agent shall initially countersign, by either manual or facsimile signature, and deliver Warrant Certificates entitling the Holders thereof to purchase in the aggregate not more than 11,479,592 shares of Common Stock (subject to adjustment as provided in such Warrant Certificates) upon a written order of the Company signed by one Officer of the Company. Each Warrant Certificate shall be dated the date of its countersignature by the Warrant Agent.

At any time and from time to time after the execution of this Agreement, the Warrant Agent shall upon receipt of a written order of the Company signed by an Officer of the Company countersign, by either manual or facsimile signature, for issue a Warrant Certificate evidencing the number of Warrants specified in such order; provided, however, that the Warrant Agent shall be entitled to receive an Officers’ Certificate and an Opinion of Counsel of the Company in connection with such countersignature of Warrants to the effect that issuance and execution of such Warrants is authorized or permitted by this Agreement. Such order shall specify the number of Warrants to be evidenced on the Warrant Certificate to be countersigned, the date on which such Warrant Certificate is to be countersigned and the number of Warrants then authorized.

The Warrants evidenced by a Warrant Certificate shall not be valid until an authorized signatory of the Warrant Agent countersigns the Warrant Certificate either manually or by facsimile signature. Such signature shall be solely for the purpose of authenticating the Warrant Certificate and shall be conclusive evidence that the Warrant Certificate so countersigned has been duly authenticated and issued under this Agreement.

Section 2.03. Registry.

The Warrants shall be issued in registered form only. The Warrant Agent shall keep a registry (the “Registry”) of the Warrant Certificates and of their transfer and exchange. The Registry shall show the names and addresses of the respective Holders and the date and number of Warrants evidenced on the face of each of the Warrant Certificates. The Holder of any Global Warrant will be the Depositary or a nominee of the Depositary in whose name the Global Warrant is registered. The Warrant holdings of Agent Members will be recorded on the books of the Depositary. The beneficial interests in the Global Warrant held by customers of Agent

Members will be reflected on the books and records of such Agent Members and will not be known to the Warrant Agent, the Company or to the Depositary.

Except as otherwise provided herein or in the Warrant Certificate, the Company and the Warrant Agent may deem and treat any Person in whose name a Warrant Certificate is registered in the Registry as the absolute owner of such Warrant Certificate for all purposes whatsoever and neither the Company nor the Warrant Agent shall be affected by notice to the contrary.

Section 2.04. Transfer and Exchange.

(a) Transfer and Exchange of Global Warrants.

(i) Registration of the transfer and exchange of Global Warrants or beneficial interests therein shall be effected through the book-entry system maintained by the Depositary, in accordance with this Agreement and the Warrant Certificates and the procedures of the Depositary therefor. A transferor of a beneficial interest in a Global Warrant (or the relevant Agent Member on behalf of such transferor) shall deliver to the Warrant Agent (x) a written order given in accordance with the Depositary’s procedures containing information regarding the account of the Agent Member to be credited with a beneficial interest in the Global Warrant and (y) a written instruction of transfer in form satisfactory to the Warrant Agent, duly executed by the Holder thereof or by his attorney, duly authorized in writing. Additionally, prior to the Holder registering the transfer or making the exchange as requested, the requirements for such transfer or exchange to be issued in a name other than the registered Holder shall be met. Such requirements include, inter alia, a signature guarantee from an eligible guarantor institution participating in a signature guarantee program approved by the Securities Transfer Association, and any other reasonable evidence of authority that may be required by the Warrant Agent. Upon satisfaction of the conditions in this Clause (i), the Warrant Agent shall, in accordance with such instructions, instruct the Depositary to credit to the account of the Agent Member specified in such instructions a beneficial interest in the Global Warrant and to debit the account of the Agent Member making the transfer of the beneficial interest in the Warrant being transferred.

(ii) Notwithstanding any other provisions of this Agreement (other than the provisions set forth in Section 2.05), a Global Warrant may only be transferred as a whole, and not in part, and only by (i) the Depositary, to a nominee of the Depositary, (ii) a nominee of the Depositary, to the Depositary or another nominee of the Depositary, or (iii) the Depositary or any such nominee to a successor Depositary or its nominee.

(iii) In the event that a Global Warrant is exchanged and transferred for Definitive Warrants pursuant to Section 2.05, such Warrants may be exchanged only in accordance with such procedures as are substantially consistent with the provisions of this Section 2.04 and the requirements of any Warrant Certificate and such other

procedures as may from time to time be adopted by the Company that are not inconsistent with the terms of this Agreement or of any Warrant Certificate.

(b) Cancellation or Adjustment of Global Warrant. At such time as all beneficial interests in a Global Warrant have been exchanged for Definitive Warrants, redeemed, repurchased or canceled, such Global Warrant shall be returned to the Depositary for cancellation or retained and canceled by the Warrant Agent. At any time prior to such cancellation, if any beneficial interest in a Global Warrant is transferred or exchanged for Definitive Warrants, redeemed, repurchased or canceled, the number of Warrants represented by such Global Warrant shall be reduced and an adjustment shall be made on the books and records of the Warrant Agent to reflect such reduction.

(i) To permit registrations of transfers and exchanges, the Company shall execute and the Warrant Agent shall countersign, by either manual or facsimile signature, Global Warrants and Definitive Warrants as required pursuant to the provisions of Section 2.02 and this Section 2.04.

(ii) No service charge shall be made to a Holder for any registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any transfer tax, assessments, or similar governmental charge payable in connection therewith.

(iii) All Warrants issued upon any registration of transfer or exchange pursuant to the terms of this Agreement shall be the valid obligations of the Company, entitled to the same benefits under this Agreement as the Warrants surrendered upon such registration for transfer or exchange.

(d) No Obligation of the Warrant Agent.

(i) The Warrant Agent shall have no responsibility or obligation to any beneficial owner of a Global Warrant, any Agent Member or other Person with respect to the accuracy of the records of the Depositary or its nominee or of any participant or member thereof, with respect to any ownership interest in the Warrants or with respect to the delivery to any Agent Member, beneficial owner or other Person (other than the Depositary) of any notice or the payment of any amount, under or with respect to such Warrants. All notices and communications to be given to the Holders and all payments to be made to Holders under the Warrants shall be given or made only to or upon the order of the registered Holders (which shall be the Depositary or its nominee in the case of a Global Warrant). The rights of beneficial owners in any Global Warrant shall be exercised only through the Depositary subject to the applicable rules and procedures of the Depositary. The Warrant Agent may rely and shall be fully protected in relying upon information furnished by the Depositary with respect to its members, participants and any beneficial owners.

(ii) The Warrant Agent shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Agreement or under applicable law with respect to any transfer of any interest in any Warrant (including any transfer between or among the Agent Members or beneficial owners in any Global Warrant) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of this Agreement, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

Section 2.05. Definitive Warrants.

(a) Beneficial interests in a Global Warrant deposited with the Depositary or with the Warrant Agent as custodian for the Depositary pursuant to Section 2.01 shall be transferred to each beneficial owner thereof in the form of Definitive Warrants evidencing a number of Warrants equivalent to such owner’s beneficial interest in such Global Warrant, in exchange for such Global Warrant, only if such transfer complies with Section 2.04 and (i) the Depositary notifies the Company that it is unwilling or unable to continue as Depositary for such Global Warrant or if at any time the Depositary ceases to be a “clearing agency” registered under the Exchange Act and, in each such case, a successor Depositary is not appointed by the Company within 90 days of such notice, (ii) the Company, in its sole discretion, notifies the Warrant Agent in writing that it elects to cause the issuance of Definitive Warrants under this Agreement, or (iii) the Company shall be adjudged a bankrupt or insolvent or makes an assignment for the benefit of its creditors or institutes proceedings to be adjudicated a bankrupt or shall consent to the filing of a bankruptcy proceeding against it, or shall file a petition or answer or consent seeking reorganization under Federal bankruptcy laws or any other similar applicable Federal or State law, or shall consent to the filing of any such petition, or shall consent to the appointment of a receiver or custodian of all or any substantial part of its property, or shall admit in writing its inability to pay or meet its debts as they mature, or if a receiver or custodian of it or all or any substantial part of its property shall be appointed, or if a public officer shall have taken charge or control of the Company or of its property or affairs, for the purpose of rehabilitation, conservation or liquidation.

(b) Any Global Warrant that is transferable to the beneficial owners thereof in the form of Definitive Warrants pursuant to this Section 2.05 shall be surrendered by the Depositary to the Warrant Agent to be so transferred, in whole or from time to time in part, without charge, and the Warrant Agent shall countersign, by either manual or facsimile signature, and deliver to each beneficial owner in the name of such beneficial owner, upon such transfer of each portion of such Global Warrant, Definitive Warrants evidencing a number of Warrants equivalent to such beneficial owner’s beneficial interest in the Global Warrant. The Warrant Agent shall register such transfer in the Registry, and upon such transfer the surrendered Global Warrant shall be cancelled by the Warrant Agent.

(c) All Definitive Warrants issued upon registration of transfer pursuant to this Section 2.05 shall be the valid obligations of the Company, evidencing the same obligations of the Company and entitled to the same benefits under this Agreement and the Global Warrant surrendered for registration of such transfer.

(d) Subject to the provisions of Section 2.05(b), the registered Holder of a Global Warrant may grant proxies and otherwise authorize any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action that a Holder is entitled to take under this Agreement or the Warrants.

(e) In the event of the occurrence of any of the events specified in Section 2.05(a), the Company will promptly make available to the Warrant Agent a reasonable supply of Definitive Warrants in definitive, fully registered form.

(f) Neither the Company nor the Warrant Agent will be liable or responsible for any registration or transfer of any Warrants that are registered or to be registered in the name of a fiduciary or the nominee of a fiduciary.

Section 2.06. Replacement Certificates.

If a mutilated Warrant Certificate is surrendered to the Warrant Agent or if the Holder of a Warrant Certificate provides proof reasonably satisfactory to the Company and the Warrant Agent that the Warrant Certificate has been lost, destroyed or wrongfully taken, the Company shall issue and the Warrant Agent shall countersign, by either manual or facsimile signature, a replacement Warrant Certificate of like tenor and representing an equivalent number of Warrants, if the reasonable requirements of the Warrant Agent and of Section 8-405 of the Uniform Commercial Code as in effect in the State of New York are met. If required by the Warrant Agent or the Company, such Holder shall furnish an indemnity bond sufficient in the reasonable judgment of the Company and the Warrant Agent to protect the Company and the Warrant Agent from any loss that either of them may suffer if a Warrant Certificate is replaced. The Company and the Warrant Agent may charge the Holder for their expenses in replacing a Warrant Certificate. Every replacement Warrant Certificate evidences an additional obligation of the Company.

Section 2.07. Outstanding Warrants.

The Warrants outstanding at any time are all Warrants evidenced on all Warrant Certificates authenticated by the Warrant Agent, except for those canceled by it and those delivered to it for cancellation. A Warrant ceases to be outstanding if the Company or an Affiliate of the Company holds the Warrant.

If a Warrant Certificate is replaced pursuant to Section 2.06, the Warrants evidenced thereby cease to be outstanding unless the Warrant Agent and the Company receive proof satisfactory to them that the replaced Warrant Certificate is held by a bona fide purchaser.

Section 2.08. Cancellation.

In the event the Company shall purchase or otherwise acquire Definitive Warrants, the same shall thereupon be delivered to the Warrant Agent for cancellation.

The Warrant Agent and no one else shall cancel and destroy all Warrant Certificates surrendered for registration of transfer, exchange, replacement, exercise or cancellation and deliver a certificate of such destruction to the Company, unless the Company directs the Warrant Agent to deliver canceled Warrant Certificates to the Company. The Company may not issue new Warrant Certificates to replace Warrant Certificates to the extent they evidence Warrants that have been exercised or Warrants that the Company has purchased or otherwise acquired.

Section 2.09. CUSIP Numbers.

The Company, in issuing the Warrants, may use “CUSIP” numbers (if then generally in use) and, if so, the Warrant Agent shall use “CUSIP” numbers in notices as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Warrant Certificates or as contained in any notice and that reliance may be placed only on the other identification numbers printed on the Warrant Certificates.

ARTICLE III

Section 3.01. Exercise.

The Exercise Price of each Warrant, the Warrant Share Number, the number of Warrants evidenced by any Warrant Certificate and the Expiration Time of each Warrant shall be set forth in the related Warrant Certificate.

(a) The Warrant Agent is hereby authorized to requisition from time to time from any stock transfer agents of the Company stock certificates required to honor outstanding Warrants upon exercise thereof in accordance with the terms of this Agreement, and the Company agrees to authorize and direct such transfer agents to comply with all such requests of the Warrant Agent. The Company shall supply such transfer agents with duly executed stock certificates for such purposes and shall provide or otherwise make available any cash or scrip that may be payable upon exercise of Warrants as provided herein and in each Warrant Certificate.

(b) The Warrant Agent is hereby authorized to create a special account for the reserve of shares of Common Stock to be issued upon exercise of the Warrants.

(ii) validly issued, fully paid and non-assessable.

ARTICLE IV

ANTIDILUTION PROVISIONS

Section 4.01. Antidilution Adjustments; Notice of Adjustment.

The Exercise Price and the Warrant Share Number shall be subject to adjustment from time to time as provided in Section 12 of the Warrant Certificate. Whenever the Exercise Price or the Warrant Share Number is so adjusted or is proposed to be adjusted as provided in Section 12 of the Warrant Certificate, the Company shall deliver to the Warrant Agent the notices or statements, and shall cause a copy of such notices or statements to be sent or communicated to each Holder pursuant to Section 6.03, as provided in Sections 12(H) and (I) of the Warrant Certificate.

Section 4.02. Adjustment to Warrant Certificate.

The form of Warrant Certificate need not be changed because of any adjustment made pursuant to the Warrant Certificate, and Warrant Certificates issued after such adjustment may state the same Exercise Price and the same Warrant Share Number as are stated in the Warrant Certificates initially issued pursuant to this Agreement. The Company, however, may at any time in its sole discretion make any change in the form of Warrant Certificate that it may deem appropriate to give effect to such adjustments and that does not affect the substance of the Warrant Certificate, and any Warrant Certificate thereafter issued or countersigned, whether in exchange or substitution for an outstanding Warrant Certificate or otherwise, may be in the form as so changed.

Section 5.03. Individual Rights of Warrant Agent.

The Warrant Agent and any stockholder, director, officer or employee of the Warrant Agent may buy, sell or deal in any of the Warrants or other securities of the Company or its affiliates or become pecuniarily interested in transactions in which the Company or its affiliates may be interested, or contract with or lend money to the Company or its affiliates or otherwise act as fully and freely as though it were not the Warrant Agent under this Agreement. Nothing herein shall preclude the Warrant Agent from acting in any other capacity for the Company or for any other legal entity.

Section 5.04. Warrant Agent’s Disclaimer.

The Warrant Agent shall not be responsible for, and makes no representation as to the validity or adequacy of, this Agreement (except the due and valid authorized execution and delivery of this Agreement by the Warrant Agent) or the Warrant Certificates (except the due countersignature of the Warrant Certificate(s) by the Warrant Agent) and it shall not be responsible for any statement in this Agreement or the Warrant Certificates other than its countersignature thereon.

Section 5.05. Compensation and Indemnity.

(a) The Company agrees to pay the Warrant Agent from time to time reasonable compensation for its services as agreed and to reimburse the Warrant Agent upon request for all reasonable out-of-pocket expense incurred by it, including the reasonable compensation and expenses of the Warrant Agent’s agents and counsel incurred by the Warrant Agent in connection with the services rendered by it under this Agreement as agreed. The Company shall indemnify the Warrant Agent, its officers and directors against any loss, liability or expense (including reasonable attorneys’ fees and expenses) incurred by it without negligence, willful misconduct or bad faith on its part arising out of or in connection with the acceptance or performance of its duties under this Agreement. The Warrant Agent shall notify the Company promptly of any claim for which it may seek indemnity. The Company need not reimburse any expense or indemnify against any loss or liability incurred by the Warrant Agent through willful misconduct, gross negligence or bad faith.

failure to comply with the terms of this Agreement, or which arise out of Warrant Agent’s negligence, bad faith or willful misconduct or which arise out of the breach of any representation or warranty of the Warrant Agent hereunder, for which the Warrant Agent is not entitled to indemnification under this Agreement; provided, however, the Warrant Agent’s aggregate liability hereunder during any term of this Agreement with respect to, arising from, or arising in connection with this Agreement, whether in contract, or in tort, or otherwise, is limited to, and shall not exceed, the amounts paid hereunder by the Company to the Warrant Agent as fees and charges, but not including reimbursable expenses.

Section 5.06. Successor Warrant Agent.

The Warrant Agent may at any time resign 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 not be less than 60 days after the date on which such notice is given unless the Company otherwise agrees.

Upon the appointment as aforesaid of a successor Warrant Agent and acceptance by the successor Warrant Agent of such appointment, the Warrant Agent shall cease to be Warrant Agent hereunder; provided, however, that in the event of the resignation of the Warrant Agent under this subsection (c), such resignation shall be effective on the earlier of (i) the date specified in the Warrant Agent’s notice of resignation and (ii) the appointment and acceptance of a successor Warrant Agent hereunder.

Section 6.02. Amendment.

This Agreement and the Warrants may be amended by the parties hereto without the consent of any Holder for the purpose of curing any ambiguity, or of curing, correcting or

supplementing any defective provision contained herein or therein or adding or changing any other provisions with respect to matters or questions arising under this Agreement or the Warrants as the Company and the Warrant Agent may deem necessary or desirable; provided, however, that such action shall not adversely affect the rights of any of the Holders in any material respect. Any amendment or supplement to this Agreement or the Warrants that has a material adverse effect on the interests of any of the Holders or owners of a beneficial interest in a Global Warrant shall require the written consent of the Holders of a majority of the then outstanding Warrants; provided that the consent of each Holder affected thereby shall be required for any amendment pursuant to which (i) the Exercise Price would be increased or the Warrant Share Number would be decreased (in each case, other than pursuant to adjustments provided for in Section 12 of the Warrant Certificate), (ii) the time period during which the Warrants are exercisable would be shortened or (iii) any change adverse to the Holder would be made to the anti-dilution provisions set forth in Article IV of this Agreement or Section 12 of the Warrant Certificate. In determining whether the Holders of the required number of Warrants have concurred in any direction, waiver or consent, Warrants owned by the Company or by any Affiliate of the Company shall be disregarded and deemed not to be outstanding, except that, for the purpose of determining whether the Warrant Agent shall be protected in relying on any such direction, waiver or consent, only Warrants that the Warrant Agent knows are so owned shall be so disregarded. Also, subject to the foregoing, only Warrants outstanding at the time shall be considered in any such determination. The Warrant Agent shall have no duty to determine whether any such amendment would have an effect on the rights or interests of the holders of the Warrants. Upon receipt by the Warrant Agent of an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent to the execution of the amendment have been complied with and such execution is permitted by this Agreement and the Warrant Certificate, the Warrant Agent shall join in the execution of such amendment; provided, that the Warrant Agent may, but shall not be obligated to, execute any amendment or supplement which adversely affects the rights or increases the duties or obligations of the Warrant Agent.

The Warrant Share Number and the Exercise Price are subject to adjustment as provided herein, and all references to “Warrant Share Number” and “Exercise Price” herein shall be deemed to include any such adjustment or series of adjustments.

3. Exercise of Warrant; Term. Subject to Section 2, to the extent permitted by applicable laws and regulations, all or a portion of the Warrants evidenced by this Warrant Certificate are exercisable by the Warrantholder, at any time or from time to time, after the execution and delivery of this Warrant Certificate by the Company on the date hereof, but in no

event later than 5:00 p.m., New York City time on the tenth anniversary of the Issue Date (the “Expiration Time”), by (A) delivery to the Warrant Agent of a Notice of Exercise in the form annexed hereto, duly completed and executed (or to the Company or to such other office or agency of the Company in the United States as the Company may designate by notice in writing to the Warrantholders pursuant to Section 18), and (B) payment of the Exercise Price for the Shares thereby purchased by having the Company withhold, from the shares of Common Stock that would otherwise be delivered to such Warrantholder upon such exercise, Shares issuable upon exercise of the Warrants so exercised equal in value to the aggregate Exercise Price as to such Shares, based on the Market Price of the Common Stock on the trading day on which such Warrants are exercised and the Notice of Exercise is delivered to the Warrant Agent pursuant to this Section 3.

In the case of a Global Warrant, any person with a beneficial interest in such Global Warrant shall effect compliance with the requirements in clauses (A) and (B) above through the relevant Agent Member in accordance with procedures of the Depositary.

In the case of a Global Warrant, whenever some but not all of the Warrants represented by such Global Warrant are exercised in accordance with the terms thereof and of the Warrant Agreement, such Global Warrant shall be surrendered by the Warrantholder to the Warrant Agent, which shall cause an adjustment to be made to Schedule A to such Global Warrant so that the number of Warrants represented thereby will be equal to the number of Warrants theretofor represented by such Global Warrant less the number of Warrants then exercised. The Warrant Agent shall thereafter promptly return such Global Warrant to the Warrantholder or its nominee or custodian. In the case of a Definitive Warrant, whenever some but not all of the Warrants represented by such Definitive Warrant are exercised in accordance with the terms thereof and of the Warrant Agreement, the Warrantholder shall be entitled, at the request of such Warrantholder, to receive from the Company within a reasonable time not to exceed three business days, a new Definitive Warrant in substantially identical form for the number of Warrants equal to the number of Warrants theretofor represented by such Definitive Warrant less the number of Warrants then exercised.

If this Warrant Certificate shall have been exercised in full, the Warrant Agent shall promptly cancel such certificate following its receipt from the Warrantholder or the Depositary, as applicable.

Notwithstanding anything in this Warrant Certificate to the contrary, in the case of Warrants evidenced by a Global Warrant any Agent Member may, without the consent of the Warrant Agent or any other person, on its own behalf and on behalf of any beneficial owner for which it is acting, enforce, and may institute and maintain, any suit, action or proceeding against the Company suitable to enforce, or otherwise in respect of, its right to exercise, and to receive Shares for, its Warrants as provided in the Global Warrant, and to enforce the Warrant Agreement.

4. Issuance of Shares; Authorization; Listing. Shares issued upon exercise of Warrants evidenced by this Warrant Certificate shall be (i) issued in such name or names as the exercising Warrantholder may designate and (ii) delivered by the Transfer Agent to such

Warrantholder or its nominee or nominees (A) via book-entry transfer crediting the account of such Warrantholder (or the relevant Agent Member for the benefit of such Warrantholder) through the Depositary’s DWAC system (if the Transfer Agent participates in such system), or (B) otherwise in certificated form by physical delivery to the address specified by the Warrantholder in the Notice of Exercise. The Company shall use its commercially reasonable efforts to cause its Transfer Agent to be a participant in the Depositary’s DWAC system. The Company shall cause the number of full Shares to which such Warrantholder shall be entitled to be so delivered by the Transfer Agent within a reasonable time, not to exceed three business days, after the date on which Warrants evidenced by this Warrant Certificate have been duly exercised in accordance with the terms hereof.

The Company hereby represents and warrants that any Shares issued upon the exercise of Warrants evidenced by this Warrant Certificate in accordance with the provisions of Section 3 will be duly and validly authorized and issued, fully paid and nonassessable and free from all taxes, liens and charges (other than liens or charges created by a Warrantholder, income and franchise taxes incurred in connection with the exercise of the Warrant or taxes in respect of any transfer occurring contemporaneously therewith). The Company agrees that the Shares so issued will be deemed to have been issued to a Warrantholder as of the close of business on the date on which Warrants evidenced by this Warrant Certificate have been duly exercised, notwithstanding that the stock transfer books of the Company may then be closed or certificates representing such Shares may not be actually delivered on such date. The Company will at all times until the Expiration Time (or, if such date shall not be a business day, then on the next succeeding business day) reserve and keep available, out of its authorized but unissued Common Stock, solely for the purpose of providing for the exercise of Warrants evidenced by this Warrant Certificate, the aggregate number of shares of Common Stock then issuable upon exercise hereof at any time. The Company will (A) procure, at its sole expense, the listing of the Shares issuable upon exercise hereof at any time, subject to issuance or notice of issuance, on all principal stock exchanges on which the Common Stock is then listed or traded and (B) maintain such listings of such Shares at all times after issuance. The Company will use reasonable best efforts to ensure that the Shares may be issued without violation of any applicable law or regulation or of any requirement of any securities exchange on which the Shares are listed or traded.

5. No Fractional Shares or Scrip. No fractional Shares or scrip representing fractional Shares shall be issued upon any exercise of Warrants evidenced by this Warrant Certificate. In lieu of any fractional Share that would otherwise be issued to a Warrantholder upon the exercise of any Warrants, such Warrantholder shall be entitled to receive a cash payment equal to the Market Price of the Common Stock on the trading day on which such warrants are exercised representing such fractional Share. The beneficial owners of the Warrants and the Warrantholder, by their acceptance hereof, expressly waive their right to receive any fraction of a share of Common Stock or a certificate representing a fraction of a share of Common Stock or Warrant Certificate representing a fractional Warrant upon exercise of any Warrant.

6. No Rights as Stockholders; Transfer Books. Warrants evidenced by this Warrant Certificate do not entitle the Warrantholder or the owner of any beneficial interest in such Warrants to any voting rights or other rights as a stockholder of the Company prior to the date of

exercise hereof. The Company will at no time close its transfer books against transfer of Warrants in any manner which interferes with the timely exercise hereof.

7. Charges, Taxes and Expenses. Issuance of Shares in certificated or book-entry form to the Warrantholder upon the exercise of Warrants evidenced by this Warrant Certificate shall be made without charge to the Warrantholder for any issue or transfer tax or other incidental expense in respect of the issuance of such Shares (other than liens or charges created by a Warrantholder, income and franchise taxes incurred in connection with the exercise of the Warrant or taxes in respect of any transfer occurring contemporaneously therewith), all of which taxes and expenses shall be paid by the Company.

8. Transfer/Assignment. This Warrant Certificate and all rights hereunder are transferable, in whole or in part, upon the books of the Company (or an agent duly appointed by the Company) by the registered holder hereof in person or by duly authorized attorney, and one or more new Warrant Certificates shall be made and delivered by the Company, of the same tenor and date as this Warrant Certificate but registered in the name of one or more transferees, upon surrender of this Warrant Certificate, duly endorsed, to the office or agency of the Company described in Section 3; provided that if this Warrant Certificate is a Global Warrant registered in the name of the Depositary, transfers of such Global Warrant may only be made as a whole, and not in part, and only by (i) the Depositary to a nominee of the Depositary, (ii) a nominee of the Depositary to the Depositary or another nominee of the Depositary or (iii) the Depositary or any such nominee to a successor Depositary or its nominee. All expenses (other than stock transfer taxes) and other charges payable in connection with the preparation, execution and delivery of the new Warrant Certificates pursuant to this Section 8 shall be paid by the Company.

If this Warrant Certificate is a Global Warrant, then so long as the Global Warrant is registered in the name of the Depositary, the holders of beneficial interests in the Warrants evidenced thereby shall have no rights under this Warrant Certificate with respect to the Global Warrant held on their behalf by the Depositary or the Warrant Agent as its custodian, and the Depositary 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 except to the extent set forth herein. Accordingly, any such owner’s beneficial interest in the Global Warrant will be shown only on, and the transfer of such interest shall be effected only through, records maintained by the Depositary or the Agent Members, and neither the Company nor the Warrant Agent shall have any responsibility with respect to such records maintained by the Depositary or the Agent Members. Notwithstanding the foregoing, nothing herein shall (i) 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 Depositary or (ii) impair, as between the Depositary and the Agent Members, the operation of customary practices governing the exercise of the rights of a holder of a beneficial interest in any Warrant. Except as may otherwise be provided in this Warrant Certificate or the Warrant Agreement, the rights of beneficial owners in a Global Warrant shall be exercised through the Depositary subject to the applicable procedures of the Depositary. Any holder of the Global Warrant shall, by acceptance of the Global Warrant, agree that transfers of beneficial interests in the Global Warrant may be effected only through a book-entry system maintained by the

Depositary, and that ownership of a beneficial interest in the Warrants represented thereby shall be required to be reflected in book-entry form.

A Global Warrant shall be exchanged for Definitive Warrants, and Definitive Warrants may be transferred or exchanged for a beneficial interest in a Global Warrant, only at such times and in the manner specified in the Warrant Agreement. Subject to the provisions of the Warrant Agreement, the holder of a Global Warrant may grant proxies and otherwise authorize any person, including Agent Members and persons that may hold beneficial interests in such Global Warrant through Agent Members, to take any action that a Warrantholder is entitled to take under a Warrant or the Warrant Agreement.

9. Exchange and Registry of Warrants. This Warrant Certificate is exchangeable, upon the surrender hereof by the Warrantholder to the Company, for a new Warrant Certificate or Warrant Certificates of like tenor and representing the same aggregate number of Warrants. The Company or an agent duly appointed by the Company (which initially shall be the Warrant Agent) shall maintain a Registry showing the name and address of the Warrantholder as the registered holder of this Warrant Certificate. This Warrant Certificate may be surrendered for exchange or exercise in accordance with its terms, at the office of the Company or any such agent, and the Company shall be entitled to rely in all respects, prior to written notice to the contrary, upon such Registry.

10. Loss, Theft, Destruction or Mutilation of Warrant Certificate. Upon receipt by the Company of proof reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Warrant Certificate, and in the case of any such loss, theft or destruction, upon receipt of a bond, indemnity or security reasonably satisfactory to the Company and the Warrant Agent, or, in the case of any such mutilation, upon surrender and cancellation of this Warrant Certificate, the Company shall make and deliver, in lieu of such lost, stolen, destroyed or mutilated Warrant Certificate, a new Warrant Certificate of like tenor and representing the same aggregate number of Warrants as provided for in such lost, stolen, destroyed or mutilated Warrant Certificate.

11. Saturdays, Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right required or granted herein shall not be a business day, then such action may be taken or such right may be exercised on the next succeeding day that is a business day.

12. Adjustments and Other Rights. The Exercise Price and the Warrant Share Number shall be subject to adjustment from time to time as follows; provided that if more than one subsection of this Section 12 is applicable to a single event, the subsection shall be applied that produces the largest adjustment and no single event shall cause an adjustment under more than one subsection of this Section 12 so as to result in duplication:

(A) Stock Splits, Subdivisions, Reclassifications or Combinations. If the Company shall (i) declare and pay a dividend or make a distribution on its Common Stock in shares of Common Stock, (ii) subdivide or reclassify the outstanding shares of Common Stock into a greater number of shares, or (iii) combine or reclassify the outstanding shares of Common Stock into a smaller number of shares, the Warrant Share Number at the time of the record date for such dividend or distribution or the effective date of such subdivision, combination or

reclassification shall be proportionately adjusted so that the holder of a Warrant after such date shall be entitled to purchase the number of shares of Common Stock which such holder would have owned or been entitled to receive in respect of the Warrant Share Number had such Warrant been exercised immediately prior to such date. In such event, the Exercise Price in effect immediately prior to the record date for such dividend or distribution or the effective date of such subdivision, combination or reclassification shall be adjusted by multiplying such Exercise Price by the quotient of (x) the Warrant Share Number immediately prior to such adjustment divided by (y) the new Warrant Share Number determined pursuant to the immediately preceding sentence.

(B) Other Distributions. In case the Company shall fix a record date for the making of a distribution to all holders of shares of its Common Stock of securities, evidences of indebtedness, assets, cash, rights or warrants (excluding Ordinary Cash Dividends, dividends of its Common Stock and other dividends or distributions referred to in Section 12(A)), in each such case, the Exercise Price in effect prior to such record date shall be reduced immediately thereafter to the price determined by multiplying the Exercise Price in effect immediately prior to the reduction by the quotient of (x) the Market Price of the Common Stock on the last trading day preceding the first date on which the Common Stock trades regular way on the principal national securities exchange on which the Common Stock is listed or admitted to trading without the right to receive such distribution, minus the amount of cash and/or the Fair Market Value of the securities, evidences of indebtedness, assets, rights or warrants to be so distributed in respect of one share of Common Stock (such subtracted amount and/or Fair Market Value, the “Per Share Fair Market Value”) divided by (y) such Market Price on such date specified in clause (x); such adjustment shall be made successively whenever such a record date is fixed. In such event, the Warrant Share Number shall be increased to the number obtained by multiplying the Warrant Share Number immediately prior to such adjustment by the quotient of (x) the Exercise Price in effect immediately prior to the distribution giving rise to this adjustment divided by (y) the new Exercise Price determined in accordance with the immediately preceding sentence. In the case of adjustment for a cash dividend that is, or is coincident with, a regular quarterly cash dividend, the Per Share Fair Market Value would be reduced by the per share amount of the portion of the cash dividend that would constitute an Ordinary Cash Dividend. In the event that such distribution is not so made, the Exercise Price and the Warrant Share Number then in effect shall be readjusted, effective as of the date when the Board of Directors determines not to distribute such shares, evidences of indebtedness, assets, rights, cash or warrants, as the case may be, to the Exercise Price and the Warrant Share Number that would then be in effect if such record date had not been fixed.

(C) Certain Repurchases of Common Stock. In case the Company effects a Pro Rata Repurchase of Common Stock, then the Exercise Price shall be reduced to the price determined by multiplying the Exercise Price in effect immediately prior to the Effective Date of such Pro Rata Repurchase by a fraction of which the numerator shall be (i) the product of (x) the number of shares of Common Stock outstanding immediately before such Pro Rata Repurchase and (y) the Market Price of a share of Common Stock on the trading day immediately preceding the first public announcement by the Company or any of its Affiliates of the intent to effect such Pro Rata Repurchase, minus (ii) the aggregate purchase price of the Pro Rata Repurchase, and of which the denominator shall be the product of (i) the number of shares of Common Stock outstanding immediately prior to such Pro Rata Repurchase minus the number of shares of Common Stock so

repurchased and (ii) the Market Price per share of Common Stock on the trading day immediately preceding the first public announcement by the Company or any of its Affiliates of the intent to effect such Pro Rata Repurchase. In such event, the Warrant Share Number shall be increased to the number obtained by multiplying the Warrant Share Number immediately prior to such adjustment by the quotient of (x) the Exercise Price in effect immediately prior to the Pro Rata Repurchase giving rise to this adjustment divided by (y) the new Exercise Price determined in accordance with the immediately preceding sentence. For the avoidance of doubt, no increase to the Exercise Price or decrease in the Warrant Share Number shall be made pursuant to this Section 12(C).

(D) Business Combinations or Reclassifications of Common Stock. In case of any Business Combination or reclassification of Common Stock (other than a reclassification of Common Stock referred to in Section 12(A)), a Warrantholder’s right to receive Shares upon exercise of a Warrant shall be converted into the right to exercise such Warrant to acquire the number of shares of stock or other securities or property (including cash) which the Common Stock issuable (at the time of such Business Combination or reclassification) upon exercise of such Warrant immediately prior to such Business Combination or reclassification would have been entitled to receive upon consummation of such Business Combination or reclassification; and in any such case, if necessary, the provisions set forth herein with respect to the rights and interests thereafter of the Warrantholder shall be appropriately adjusted so as to be applicable, as nearly as may reasonably be, to such Warrantholder’s right to exercise a Warrant in exchange for any shares of stock or other securities or property pursuant to this paragraph. In determining the kind and amount of stock, securities or the property receivable upon exercise of a Warrant following the consummation of such Business Combination, if the holders of Common Stock have the right to elect the kind or amount of consideration receivable upon consummation of such Business Combination, then the consideration that a Warrantholder shall be entitled to receive upon exercise shall be deemed to be the types and amounts of consideration received by the majority of all holders of the shares of Common Stock that affirmatively make an election (or of all such holders if none make an election). For purposes of determining any amount to be withheld pursuant to Section 3 from stock, securities or the property that would otherwise be delivered to a Warrantholder upon exercise of Warrants following any Business Combination, the amount of such stock, securities or property to be withheld shall have a Market Price equal to the aggregate Exercise Price as to which such Warrants are so exercised, based on the fair market value of such stock, securities or property on the trading day on which such Warrants are exercised and the Notice of Exercise is delivered to the Warrant Agent; provided that in the case of any property that is not a security, the Market Price of such property shall be deemed to be its fair market value as determined in good faith by the Board of Directors in reliance on an opinion of a nationally recognized independent investment banking firm retained by the Company for this purpose; and further provided that if making such determination requires the conversion of any currency other than U.S. dollars into U.S. dollars, such conversion shall be done in accordance with customary procedures based on the rate for conversion of such currency into U.S. dollars displayed on the relevant page by Bloomberg L.P. (or any successor or replacement service) on or by 4:00 p.m., New York City time on such exercise date.

(E) Rounding of Calculations; Minimum Adjustments. All calculations under this Section 12 shall be made to the nearest one-tenth (1/10th) of a cent or to the nearest one-hundredth (1/100th) of a share, as the case may be. Any provision of this Section 12 to the contrary notwithstanding, no adjustment in the Exercise Price or the Warrant Share Number shall

be made if the amount of such adjustment would be less than $0.01 or one-tenth (1/10th) of a share of Common Stock, but any such amount shall be carried forward and an adjustment with respect thereto shall be made at the time of and together with any subsequent adjustment which, together with such amount and any other amount or amounts so carried forward, shall aggregate $0.01 or 1/10th of a share of Common Stock, or more, or on exercise of a Warrant if it shall earlier occur.

(F) Timing of Issuance of Additional Common Stock Upon Certain Adjustments. In any case in which the provisions of this Section 12 shall require that an adjustment shall become effective immediately after a record date for an event, the Company may defer until the occurrence of such event (i) issuing to a Warrantholder of Warrants exercised after such record date and before the occurrence of such event the additional shares of Common Stock issuable upon such exercise by reason of the adjustment required by such event over and above the shares of Common Stock issuable upon such exercise before giving effect to such adjustment and (ii) paying to such Warrantholder any amount of cash in lieu of a fractional share of Common Stock; provided, however, that the Company upon request shall deliver to such Warrantholder a due ▇▇▇▇ or other appropriate instrument evidencing such Warrantholder’s right to receive such additional shares, and such cash, upon the occurrence of the event requiring such adjustment.

(G) Other Events. Neither the Exercise Price nor the Warrant Share Number shall be adjusted in the event of a change in the par value of the Common Stock or a change in the jurisdiction of incorporation of the Company.

(H) Statement Regarding Adjustments. Whenever the Exercise Price or the Warrant Share Number shall be adjusted as provided in Section 12, the Company shall forthwith file at the principal office of the Company a statement showing in reasonable detail the facts requiring such adjustment and the Exercise Price that shall be in effect and the Warrant Share Number after such adjustment. The Company shall deliver to the Warrant Agent a copy of such statement and shall cause a copy of such statement to be sent or communicated to the Warrantholders pursuant to Section 18.

(I) Notice of Adjustment Event. In the event that the Company shall propose to take any action of the type described in this Section 12 (but only if the action of the type described in this Section 12 would result in an adjustment in the Exercise Price or the Warrant Share Number or a change in the type of securities or property to be delivered upon exercise of a Warrant), the Company shall deliver to the Warrant Agent a notice and shall cause such notice to be sent or communicated to the Warrantholders in the manner set forth in Section 18, which notice shall specify the record date, if any, with respect to any such action and the approximate date on which such action is to take place. Such notice shall also set forth the facts with respect thereto as shall be reasonably necessary to indicate the effect on the Exercise Price and the number, kind or class of shares or other securities or property which shall be deliverable upon exercise of a Warrant. In the case of any action which would require the fixing of a record date, such notice shall be given at least 10 days prior to the date so fixed, and in case of all other action, such notice shall be given at least 15 days prior to the taking of such proposed action. Failure to give such notice, or any defect therein, shall not affect the legality or validity of any such action.

(J) Proceedings Prior to Any Action Requiring Adjustment. As a condition precedent to the taking of any action which would require an adjustment pursuant to this Section 12, the Company shall take any action which may be necessary, including obtaining regulatory, New York Stock Exchange, NASDAQ Stock Market or other applicable national securities exchange or stockholder approvals or exemptions, in order that the Company may thereafter validly and legally issue as fully paid and nonassessable all Shares that a Warrantholder is entitled to receive upon exercise of a Warrant pursuant to this Section 12.

(K) Adjustment Rules. Any adjustments pursuant to this Section 12 shall be made successively whenever an event referred to herein shall occur. If an adjustment in Exercise Price made hereunder would reduce the Exercise Price to an amount below par value of the Common Stock, then such adjustment in Exercise Price made hereunder shall reduce the Exercise Price to the par value of the Common Stock.

13. No Impairment. The Company will not, by amendment of its Charter or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Company, but will at all times in good faith assist in the carrying out of all the provisions of this Warrant Certificate and in taking of all such action as may be necessary or appropriate in order to protect the rights of the Warrantholder.

14. Governing Law. This Warrant Certificate and the Warrants evidenced hereby shall be governed by and construed in accordance with the laws of the State of New York applicable to contracts made and to be performed entirely within such State.

15. Binding Effect; Countersignature by Warrant Agent. This Warrant Certificate shall be binding upon any successors or assigns of the Company. This Warrant Certificate shall not be valid until an authorized signatory of the Warrant Agent (as defined below) or its agent as provided in the Warrant Agreement (as defined below) countersigns this Warrant Certificate. Such signature shall be solely for the purpose of authenticating this Warrant Certificate and shall be conclusive evidence that this Warrant Certificate has been countersigned under the Warrant Agreement.

16. Warrant Agreement; Amendments. This Warrant Certificate is issued under and in accordance with a Warrant Agreement dated as of May 6, 2010 (the “Warrant Agreement”), between the Company and ▇▇▇▇▇ Fargo Bank, N.A. (the “Warrant Agent,” which term includes any successor Warrant Agent under the Warrant Agreement), and is subject to the terms and provisions contained in the Warrant Agreement, to all of which terms and provisions the beneficial owners of the Warrants and the Warrantholders consent by acceptance hereof. The Warrant Agreement is hereby incorporated herein by reference and made a part hereof. Reference is hereby made to the Warrant Agreement for a statement of the respective rights, limitations of rights, duties and obligations of the Company, the Warrant Agent and the Warrantholders and beneficial owners of the Warrants. A copy of the Warrant Agreement may be obtained for inspection by the Warrantholders or beneficial owners of the Warrants upon request to the Warrant Agent at the address of the Warrant Agent (or successor warrant agent) set forth in the Warrant Agreement. The Warrant Agreement and this Warrant Certificate may be

amended and the observance of any term of the Warrant Agreement or this Warrant Certificate may be waived only to the extent provided in the Warrant Agreement.

17. Prohibited Actions. The Company agrees that it will not take any action which would entitle the Warrantholder to an adjustment of the Exercise Price if the total number of shares of Common Stock issuable after such action upon exercise of the Warrants evidenced by this Warrant Certificate, together with all shares of Common Stock then outstanding and all shares of Common Stock then issuable upon the exercise of all outstanding options, warrants, conversion and other rights, would exceed the total number of shares of Common Stock then authorized by its Charter.

18. Notices. Unless this Warrant Certificate is a Global Warrant, any notice or communication mailed to the Warrantholder shall be mailed to the Warrantholder at the Warrantholder’s address as it appears in the Registry and shall be sufficiently given if so mailed within the time prescribed. Any notice to holders of a beneficial interest in a Global Warrant shall be distributed through the Depositary in accordance with the procedures of the Depositary. Communications to such holders shall be deemed to be effective at the time of dispatch to the Depositary.
