hereinafter in this Agreement set forth; and the Warrant Agent hereby accepts such appointment, upon the terms and conditions hereinafter set forth.

Section 3. Issuance of Warrants; Form, Execution and Delivery.

(a) Issuance of Warrants. On the date hereof, the Company shall, pursuant to the Plan, deliver to the disbursing agent under the Plan for re-distribution to (i) each holder of NTK 10-3/4% Notes Claims, such holder’s pro rata share of 464,278 Warrants (based upon the principal amount of NTK 10-3/4% Notes (as defined in the Plan) held by such holder) and (ii) the holder of NTK Holdings Senior Unsecured Loan Claims, such holder’s pro rata share of 325,196 Warrants (based upon the principal amount of NTK Holdings Senior Unsecured Loan (as defined in the Plan) held by such holder). Each Warrant shall entitle the Holder, subject to the satisfaction of the conditions to exercise set forth in Section 5 hereof, to purchase from and after the date of issuance of Warrants to such Holder and until 5:00 p.m., New York City time, on the Expiration Date, one Warrant Share at the Exercise Price. The number of Warrants to be issued pursuant to this Agreement, the number of Warrant Shares issuable on exercise of each Warrant and the Exercise Price are all subject to adjustment pursuant to Section 6 hereof.

(b) Form of Warrant. The certificates evidencing the Warrants (collectively, the “Warrant Certificates”) to be delivered pursuant to this Agreement and the forms of election to exercise and of assignment to be printed on the reverse thereof shall be in substantially the form set forth in Exhibit A hereto, together with such appropriate insertions, omissions, substitutions and other variations as are required or permitted by this Agreement, and may have such letters, numbers or other marks of identification and such legends or endorsements placed thereon as may be required to comply with any law or with any rules made pursuant thereto or with any rules of any securities exchange or as may be determined, consistently herewith, by the officers executing such Warrant Certificates, as evidenced by their execution of the Warrant Certificates. Each Warrant Certificate shall be dated as of the date on which it is countersigned by the Warrant Agent, as described in Section 3(d) below.

The terms and provisions contained in the Warrants shall constitute, and are hereby expressly made, a part of this Agreement. The Company and the Warrant Agent, by their execution and delivery of this Agreement, expressly agree to such terms and provisions and to be bound thereby. However, to the extent any provision of any Warrant conflicts with the provisions of this Agreement, the provisions of this Agreement shall govern and be controlling.

(c) Execution of Warrants. Warrant Certificates shall be executed on behalf of the Company by its Chairman of the Board, Vice Chairman of the Board, President, any Vice President, General Counsel, Treasurer or Secretary, either manually or by facsimile signature printed thereon. In case any such officer of the Company whose signature shall have been placed upon any Warrant Certificate shall cease to be such officer of the Company before countersignature by the Warrant Agent or issuance and delivery thereof, such Warrant Certificate nevertheless may be countersigned by the Warrant Agent and issued and delivered with the same force and effect as though such person had not ceased to be such officer of the Company.

(d) Countersignature of Warrant Certificates. Warrant Certificates shall be manually countersigned by an authorized signatory of the Warrant Agent and shall not be valid

for any purpose unless and until so countersigned. Such manual countersignature shall constitute conclusive evidence of such authorization. The Warrant Agent is hereby authorized to countersign, in accordance with the provisions of this Section 3(d), and deliver any new Warrant Certificates, as and when directed by the Company pursuant to Section 3(a) hereof and as and when required pursuant to the provisions of Section 4 and Section 9 hereof. Each Warrant Certificate shall, when manually countersigned by an authorized signatory of the Warrant Agent, entitle the registered holder thereof to exercise the rights as the holder of the number of Warrants set forth thereon, subject to the provisions of this Agreement.

Section 4. Warrant Registration.

(a) Registration. The Warrant Certificates shall be issued in registered form only and shall be registered in the names of the record Holders to whom they are to be delivered (any such delivery to a registered Holder will be at its last address as shown on the register of the Company). The Warrant Agent shall maintain or cause to be maintained a register in which, subject to such reasonable regulations as it may prescribe, the Warrant Agent shall provide for the registration of Warrants and of transfers or exchanges of Warrant Certificates as provided in this Agreement. Such register shall be maintained at the Warrant Agent’s Principal Office by the Warrant Agent (the “Warrant Register”).

(b) Transfer or Exchange. At the option of the Holder, Warrant Certificates may be exchanged or transferred for other Warrant Certificates for a like aggregate number of Warrants, upon surrender of the Warrant Certificates to be exchanged at the Warrant Agent’s Principal Office, and upon payment of the taxes and charges herein provided. Whenever any Warrant Certificates are so surrendered for exchange or transfer, the Company shall execute, and an authorized signatory of the Warrant Agent shall manually countersign and deliver, the Warrant Certificates that the Holder making the exchange is entitled to receive.

(c) Valid and Enforceable. All Warrant Certificates issued upon any registration of transfer or exchange of Warrant Certificates in accordance with this Agreement shall be the valid obligations of the Company, evidencing the same obligations, and entitled to the same benefits under this Agreement, as the Warrant Certificates surrendered for such registration of transfer or exchange.

(d) Endorsement. Every Warrant Certificate surrendered for registration of transfer or exchange shall (if so required by the Company or the Warrant Agent) be duly endorsed, or be accompanied by an instrument of transfer in form reasonably satisfactory to the Company and the Warrant Agent and duly executed by the registered Holder thereof or such Holder’s officer or representative duly authorized in writing.

(e) No Service Charge. No service charge shall be made to the Warrant Holder for any registration of transfer or exchange of Warrant Certificates.

(f) Cancellation. Any Warrant Certificate surrendered for registration of transfer, exchange or the exercise of the Warrants represented thereby shall, if surrendered to the Company, be delivered to the Warrant Agent, and all Warrant Certificates surrendered or so delivered to the Warrant Agent shall be promptly cancelled by the Warrant Agent. Any such

Warrant Certificate shall not be reissued and, except as provided in this Section 4 in case of an exchange or transfer, in Section 9 in case of a mutilated Warrant Certificate and in Section 5 in case of the exercise of less than all the Warrants represented thereby, no Warrant Certificate shall be issued hereunder in lieu thereof. The Warrant Agent shall deliver to the Company from time to time or otherwise dispose of such cancelled Warrant Certificates in a reasonably prompt manner.

(g) Treatment of Holders of Warrant Certificates. The Company and the Warrant Agent may treat the registered Holder of a Warrant Certificate as the absolute owner thereof for any purpose and as the Person entitled to exercise the rights represented by the Warrants evidenced thereby, any notice to the contrary notwithstanding.

Section 5. Duration and Exercise of Warrants.

(a) Expiration Date. The Warrants shall expire on December 17, 2014, which is the fifth (5th) anniversary of the Effective Date of the Plan (the “Expiration Date”). After the Expiration Date, the Warrants will become void and of no value.

(b) Exercise Price. The Exercise Price for the Warrants shall be $52.80 per Warrant Share (subject to adjustment pursuant to Section 6 hereof).

(c) Manner of Exercise. Subject to the provisions of this Agreement, each Warrant shall entitle the Holder thereof to purchase from the Company (and the Company shall issue and sell to such Holder) one fully paid and nonassessable Warrant Share evidenced by the Warrant Certificate at a price equal to the Exercise Price. All or any of the Warrants represented by a Warrant Certificate may be exercised prior to the Expiration Date by the registered Holder thereof during normal business hours on any Business Day, by (i) surrendering such Warrant Certificate, and (ii) delivering the subscription form set forth therein duly executed by such Holder, and in each case by hand or by mail to the Warrant Agent at the Warrant Agent’s Principal Office. Such Warrant Certificate and subscription form shall be accompanied by payment in full in respect of each Warrant that is exercised (in the aggregate, the “Aggregate Exercise Price”), which shall be made by certified or official bank or bank cashier’s check payable to the order of the Company, or by wire transfer to the Warrant Agent in immediately available funds. The Aggregate Exercise Price shall be in an amount equal to the product of the number of Warrant Shares designated in such subscription form multiplied by the Exercise Price (plus such additional consideration as may be provided herein). Upon such surrender and payment, such Holder shall thereupon be entitled to receive the number of duly authorized, validly issued, fully paid and nonassessable Warrant Shares determined as provided in Section 3, and as and if adjusted pursuant to Section 6.

(d) Conversion Right. In lieu of the payment of the Aggregate Exercise Price, the Holder shall have the right (but not the obligation), to require the Company to convert each Warrant, in whole or in part, into shares of Common Stock (the “Conversion Right”) as provided for in this Section 5(d). Upon exercise of the Conversion Right, the Company shall deliver to the Holder (without payment by the Holder of any of the Aggregate Exercise Price) in accordance with Section 5(c) that number of shares of Common Stock equal to the quotient obtained by dividing (i) the value of the Warrant or portion thereof at the time the Conversion

Right is exercised (determined by subtracting the Aggregate Exercise Price at the time of the exercise of the Conversion Right from the aggregate Fair Value of the shares of Common Stock issuable upon exercise of the Warrant at the time of the exercise of the Conversion Right) by (ii) the Fair Value of one share of Common Stock at the time of the exercise of the Conversion Right.

The Conversion Right may be exercised by the Holder on any Business Day prior to the Expiration Date by surrender of this Warrant to the Company, with a duly executed subscription form completed, exercising the Conversion Right and specifying the total number of warrants with regard to which the Holder is exercising the conversion right.

(e) When Exercise Effective. Each exercise of any Warrant in accordance with Section 5(c) above shall be deemed to have been effected immediately prior to the close of business on the Business Day on which the Warrant Certificate representing such Warrant, duly executed, with accompanying payment shall have been delivered as provided in Section 5(c), and at such time the Person or Persons in whose name or names the certificate or certificates for Common Stock shall be issuable upon such exercise as provided in Section 5(f) below shall be deemed to have become the holder or holders of record thereof.

(f) Delivery of Certificates, Etc. (A) As promptly as practicable after the exercise of any Warrant, but in any event within five (5) Business Days thereafter, the Company at its expense (other than as to payment of transfer taxes which will be paid by the Holder) will issue and deliver to such Holder, or as such Holder may otherwise direct in writing (subject to Section 9 hereof),

(1) a certificate or certificates or other appropriate evidence of ownership for the number of Warrant Shares to which such Holder is entitled, and

(2) if less than all the Warrants represented by a Warrant Certificate are exercised, a new Warrant Certificate or Certificates of the same tenor and for the aggregate number of Warrants that were not exercised, executed and countersigned in accordance with Section 3(c) and Section 3(d) hereof.

(B) The Warrant Agent shall countersign any new Warrant Certificate, register it in such name or names as may be directed in writing by such Holder, and shall deliver it to the Person entitled to receive the same in accordance with this Section 5(f). The Company, whenever required by the Warrant Agent, shall supply the Warrant Agent with Warrant Certificates executed on behalf of the Company for such purpose. At the request of such Holder, the Company shall use commercially reasonable efforts to cause its transfer agent to electronically transmit such Common Shares to such Holder through the Deposit Withdrawal Agent Commission System of The Depository Trust Company.

(C) Upon any exercise of Warrants, the Warrant Agent shall, as promptly as practicable, advise the Treasurer of the Company or his or her designee of (i) the number of Warrants exercised, (ii) the instruction of each holder of the Warrant Certificates evidencing such Warrants with respect to delivery of the Common Stock to which such holder is entitled upon such exercise, (iii) the timing of delivery of Warrant Certificates evidencing the

balance, if any, of the Warrants remaining after such exercise, and (iv) such other information related thereto as the Company shall reasonably require.

(D) The Company shall not be required to pay any stamp or other tax or other governmental charge required to be paid in connection with any transfer involved in the issuance of the Common Stock to a Person other than a registered holder; and in the event that any such transfer is involved, the Company shall not be required to issue or deliver any Warrant Certificate or share of Common Stock until such tax or other charge shall have been paid or it has been established to the Company’s satisfaction that no such tax or other charge is due. The Warrant Agent shall have no duty or obligation under this Section 5 or any other similar provision of this Agreement unless and until it is satisfied that all such taxes and/or governmental charges have been paid in full.

(g) Fractional Shares. Notwithstanding any adjustment pursuant to Section 6 in the number of Warrant Shares purchasable upon the exercise of a Warrant, the Company shall not be required to issue Warrants to purchase fractions of Warrant Shares, or to issue fractions of Warrant Shares upon exercise of the Warrants, or to distribute certificates which evidence fractional Shares. In the event of an adjustment that results in a Warrant becoming exercisable for fractional Shares, the Company shall deliver an amount in cash equal to the Fair Value of the same fraction of the closing price of the Common Stock on the Exercise Date.

Section 6. Adjustment of Exercise Price and Number of Warrant Shares Purchasable or Number of Warrants.

(a) Stock Dividends, Split-ups and Combinations of Shares. If, after the date hereof, the number of outstanding shares of Common Stock is increased by a dividend or share distribution, in each case payable in shares of Common Stock, or adjusted by a split-up, combination or other reclassification of shares of Common Stock, then, in the case of such events, the amount of Common Stock issuable for each Warrant and the Exercise Price will be adjusted as follows: on the day following the date fixed for the determination of holders of shares of Common Stock entitled to receive such dividend or share distribution, and in the cases of split-ups, combinations and other reclassifications, on the day following the effective date thereof: (a) the Exercise Price in effect immediately prior to such action shall be adjusted to a new Exercise Price that bears the same relationship to the Exercise Price in effect immediately prior to such event as the total number of shares of Common Stock outstanding immediately prior to such action bears to the total number of shares of Common Stock outstanding immediately after such event, and (b) the number of shares of Common Stock purchasable upon the exercise of any Warrant after such event shall be the number of shares of Common Stock obtained by multiplying the number of shares of Common Stock purchasable immediately prior to such adjustment upon the exercise of such Warrant by the Exercise Price in effect immediately prior to such adjustment and dividing the product so obtained by the Exercise Price in effect after such adjustment.

(b) Adjustments for Mergers and Consolidations. In case the Company, after the date hereof, shall merge or consolidate with another Person, then, in the case of any such transaction, proper provision shall be made so that, upon the basis and terms and in the manner provided in this Warrant Agreement, the Holders of the Warrants, upon the exercise thereof at

any time after the consummation of such transaction (but prior to the Expiration Date) shall be entitled to receive (at the Aggregate Exercise Price in effect at the time of the transaction for all Common Stock issuable upon such exercise immediately prior to such consummation), in lieu of the Common Stock issuable upon such exercise prior to such consummation, the greatest amount of securities, cash or other property to which such holder would have been entitled as a holder of Common Stock upon such consummation if such Holder had exercised the Warrants held by such Holder immediately prior thereto, subject to adjustments (subsequent to such consummation) as nearly equivalent as possible to the adjustments provided for in Section 6(a).

(c) Notice of Adjustment in Exercise Price or Warrant Shares. Whenever the Exercise Price and/or number of Warrant Shares issuable shall be adjusted as provided in this Section 6, the Company shall forthwith file with the Warrant Agent a statement, signed by the Chairman of the Board, Vice Chairman of the Board, the President, any Vice President, General Counsel, its Treasurer, an Assistant Treasurer, its Secretary or an Assistant Secretary, summarizing the facts requiring such adjustment, the Exercise Price that will be effective after such adjustment and the impact of such adjustment on the number and kind of securities issuable upon exercise of the Warrants. The Company shall also cause a notice setting forth any such adjustments to be sent by mail, first class, postage prepaid, to each registered Holder at its address appearing on the Warrant Register. The Warrant Agent shall have no duty with respect to any statement filed with it except to keep the same on file and available for inspection by registered holders of Warrants during reasonable business hours. The Warrant Agent shall not at any time be under any duty or responsibility to any holder of a Warrant to determine whether any facts exist that may require any adjustment to the Exercise Price or securities issuable, or with respect to the nature or extent of any adjustment of the Exercise Price or securities issuable when made or with respect to the method employed in making such adjustment.

(d) No Change in Warrant Terms on Adjustment. Irrespective of any adjustments in the Exercise Price or the number of Warrant Shares issuable upon exercise, Warrants theretofore or thereafter issued may continue to express the same prices and number of shares as are stated in the similar Warrants issuable initially, or at some subsequent time, pursuant to this Agreement, and the Exercise Price and such number of shares issuable upon exercise specified thereon shall be deemed to have been so adjusted.

(e) Treasury Shares. Shares of Common Stock at any time owned by the Company or its subsidiaries shall not be deemed to be outstanding for the purposes of any computation under this Section 6.

Section 7. Change of Control.

(a) Election to Purchase upon Change of Control Event. Notwithstanding anything else contained herein, if prior to the Expiration Date, an agreement resulting in a Change of Control Event is entered into, within 30 days prior to the date of the consummation of such Change of Control Event (the “Change of Control Event Date”), the Company or the surviving Person (if other than the Company) may elect to purchase from all Holders (the “Change of Control Offer”) all, but not less than all, of the outstanding Warrants at a purchase price equal to the Change of Control Payment Amount on the Change of Control Event Date in

accordance with the procedures set forth in this Section 7 and shall notify the Warrant Agent in writing of such purchase.

(b) Payment of Change of Control Payment Amount. If the Company elects to make a Change of Control Offer, then on the Change of Control Event Date, the Company or the surviving Person (if other than the Company) shall deposit with the Warrant Agent money sufficient to pay the Change of Control Payment Amount for all Warrants. The Warrant Agent shall promptly mail to each Holder, payment in an amount equal to the applicable Change of Control Payment Amount.

Section 8. Cancellation of Warrants. The Warrant Agent shall cancel all Warrant Certificates surrendered for exchange, substitution, transfer or exercise in whole or in part by such method as it shall deem fair and appropriate. Such cancelled Warrant Certificates shall thereafter be disposed of in a manner satisfactory to the Company.

Section 9. Mutilated or Missing Warrant Certificates. Upon receipt by the Company and the Warrant Agent from any Holder of evidence reasonably satisfactory to them of the ownership of and the loss, theft, destruction or mutilation of such Holder’s Warrant Certificate and indemnity reasonably satisfactory to them, together with such additional documentation that the Company and the Warrant Agent may require, and in case of mutilation upon surrender and cancellation thereof, the Company will execute and the Warrant Agent will countersign and deliver in lieu thereof a new Warrant Certificate of like tenor and representing an equal number of Warrants to such Holder; provided in the case of mutilation, no indemnity shall be required if such Warrant Certificate in identifiable form is surrendered to the Company or the Warrant Agent for cancellation. Upon the issuance of any new Warrant Certificate under this Section 9, the Company may require the payment of a sum sufficient to cover any stamp tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the reasonable fees and expenses of the Warrant Agent) in connection therewith. Every new Warrant Certificate executed and delivered pursuant to this Section 9 in lieu of any lost, stolen or destroyed Warrant Certificate shall be entitled to the same benefits of this Agreement equally and proportionately with any and all other Warrant Certificates, whether or not the allegedly lost, stolen or destroyed Warrant Certificate shall be at any time enforceable by anyone. The provisions of this Section 9 are exclusive and shall preclude (to the extent lawful) all other rights or remedies with respect to the replacement of mutilated, lost, stolen or destroyed Warrant Certificates.

Section 10. Merger, Consolidation, Etc. Notwithstanding anything contained herein to the contrary, the Company will not effect a merger or consolidation prior to the Expiration Date unless, prior to the consummation of such transaction, each Person (other than the Company) that may be required to deliver any Common Stock, securities, cash or property upon the exercise of any Warrant as provided herein shall assume, by written instrument delivered to the Warrant Agent, the obligations of the Company under this Agreement and under each of the Warrants, including, without limitation, the obligation to deliver such shares of Common Stock, cash or property as may be required pursuant to Section 6 hereof, and shall provide for adjustments equivalent to the adjustments provided for in Section 6 hereof.

Section 11. Reservation of Shares.

(a) Reservation of Shares. The Company shall at all times reserve and keep available, free from preemptive rights, out of its authorized but unissued Common Stock, solely for issuance and delivery upon exercise of Warrants, the full number of Warrant Shares from time to time issuable upon the exercise of all Warrants. All Warrant Shares shall be duly authorized and, when issued upon such exercise, shall be duly and validly issued, and fully paid and nonassessable, and free from all taxes, liens, charges, security interests, encumbrances and other restrictions created by or through the Company.

(b) Certain Actions. Before taking any action that would cause an adjustment pursuant to Section 6 reducing any Exercise Price below the then par value (if any) of the Warrant Shares issuable upon exercise of the Warrants, the Company will take any reasonable corporate action that may, in the opinion of its counsel, be necessary in order that the Company may validly and legally issue fully paid and nonassessable Warrant Shares at such Exercise Price as so adjusted.

Section 12. Notification of Certain Events.

(a) Corporate Action. In the event of:

(A) any taking by the Company of a record of the holders of any class of securities for the purpose of determining the holders thereof who are entitled to receive any dividend (excluding cash distributions made as a dividend payable out of earnings or out of surplus legally available for dividends under the laws of the jurisdiction of incorporation of the Company) or other distribution of any kind; or

(B) (A) any capital reorganization of the Company, (B) any reclassification of the capital shares of the Company (other than a change in par value or from par value to no par value or from no par value to par value or as a result of a split-up or combination), (C) the consolidation or merger of the Company with or into any other Person (other than a consolidation or merger in which the Company is the continuing corporation and which does not result in any change in the shares of Common Stock) or (D) the sale or transfer of the properties and assets of the Company as, or substantially as, an entirety to another Person; or

the Company shall cause to be filed with the Warrant Agent and mailed to each Holder a notice specifying (x) the date or expected date on which any such record is to be taken for the purpose of such dividend or distribution, and the amount and character of any such dividend or distribution or if a record is not to be taken, the date as of which the holders of Common Stock of record to be entitled to such dividend or distribution are to be determined, and the amount and character of such dividend or distribution or (y) the date or expected date on which any such reorganization, reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding up is expected to become effective, and the time, if any such time is to be fixed, as of which holders of record of Common Stock shall be entitled to exchange their shares of Common Stock for the securities or other property deliverable upon such reorganization, reclassification, consolidation, merger, sale, transfer, exchange offer, dissolution, liquidation or winding up. Such

notice shall be delivered not less than ten (10) days prior to such date therein specified. Failure to give such notice within the time provided or any defect therein shall not affect the legality or validity of any such action.

Section 13. Warrant Agent. The Warrant Agent undertakes the duties and obligations imposed by this Agreement upon the terms and conditions set forth in this Section 13.

(a) Limitation on Liability. The Warrant Agent shall not by countersigning Warrant Certificates or by any other act hereunder be accountable with respect to or be deemed to make any representations as to the validity or authorization of the Warrants or the Warrant Certificates (except as to its countersignature thereon), as to the validity, authorization or value (or kind or amount) of any Common Stock or other property delivered or deliverable upon exercise of any Warrant, or as to the purchase price of such Common Stock, securities or other property. The Warrant Agent shall not (i) be liable for any recital or statement of fact contained herein or in the Warrant Certificates or for any action taken, suffered or omitted by the Warrant Agent in good faith in the belief that any Warrant Certificate or any other document or any signature is genuine or properly authorized, (ii) be responsible for determining whether any facts exist that may require any adjustment of the purchase price and the number of Warrant Shares purchasable upon exercise of Warrants, or with respect to the nature or extent of any such adjustments when made, or with respect to the method of adjustment employed, (iii) be responsible for any failure on the part of the Company to issue, transfer or deliver any Common Stock or property upon the surrender of any Warrant for the purpose of exercise or to comply with any other of the Company’s covenants and obligations contained in this Agreement or in the Warrant Certificates, (iv) be liable for any action taken, suffered or omitted to be taken in connection with this Agreement, except for its own bad faith, gross negligence or willful misconduct, (v) be liable for special, indirect or consequential loss or damage of any kind whatsoever (including, but not limited to, lost profits), even if the Warrant Agent has been advised of the likelihood of such loss or damage and regardless of the form of action, or (vi) be responsible for any failure of the Company to comply with any of the covenants contained in this Agreement or in the Warrant Certificates to be complied with by the Company.

(b) Instructions. The Warrant Agent is hereby authorized to accept advice or instructions with respect to the performance of its duties hereunder from the President and Chief Executive Officer, Treasurer, Chief Legal Officer, Secretary and Chief Financial Officer of the Company and to apply to any such officer for advice or instructions. The Warrant Agent shall be fully protected and authorized in relying upon the most recent advice or instructions received from any such officer. The Warrant Agent shall not be liable for any action taken, suffered or omitted by it in accordance with the advice or instructions of any such officer, except to the extent that such action or omission resulted directly from the Warrant Agent’s gross negligence, bad faith or willful misconduct.

(c) Agents. The Warrant Agent may execute and exercise any of the rights and powers hereby vested in it or perform any duty hereunder either itself or by or through its attorneys, agents or employees, provided reasonable care has been exercised in the selection and in the continued employment of such attorney, agent or employee. The Warrant Agent shall not be under any obligation or duty to institute, appear in, or defend any action, suit or legal

proceeding in respect hereof, but this provision shall not affect the power of the Warrant Agent to take such action as the Warrant Agent may consider necessary. The Warrant Agent shall promptly notify the Company in writing of any claim made or action, suit or proceeding instituted against the Warrant Agent arising out of or in connection with this Agreement.

(d) Cooperation. The Company will perform, execute, acknowledge and deliver or cause to be performed, executed, acknowledged and delivered all such further acts, instruments and assurances as may reasonably be required by the Warrant Agent in order to enable the Warrant Agent to carry out or perform its duties under this Agreement.

(e) Agent Only. The Warrant Agent shall act solely as agent for the Company in accordance with the terms and conditions hereof. The Warrant Agent shall not be liable except for the performance of such duties as are specifically set forth herein, and no implied covenants or obligations shall be read into this Agreement against the Warrant Agent, whose duties and obligations shall be determined solely by the express provisions hereof.

(f) Right to Counsel. The Warrant Agent may at any time consult with legal counsel satisfactory to it (who may be legal counsel for the Company), and the Warrant Agent shall incur no liability or responsibility to the Company or to any Warrant holder for any action taken, suffered or omitted by the Warrant Agent in good faith in reliance on the opinion or advice of such counsel.

(g) Compensation. The Company agrees to pay to the Warrant Agent reasonable compensation for all services rendered by the Warrant Agent in the execution of this Agreement, to reimburse the Warrant Agent for all expenses, taxes and governmental charges and other charges of any kind and nature incurred by the Warrant Agent in the execution of this Agreement. The Company shall indemnify the Warrant Agent against any and all losses, liabilities or expenses incurred (including reasonable counsel’s fees) by it arising out of or in connection with the acceptance or administration of its duties under this Warrant Agreement, including the costs and expenses of enforcing this Agreement against the Company and defending itself against any claim (whether asserted by the Company or any holder of the Warrants or any other person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, except to the extent any such loss, liability or expense may be attributable to its gross negligence, willful misconduct or bad faith.

(h) Force Majeure. The Warrant Agent shall not be responsible or liable for any failure or delay in the performance of its obligations under this Agreement arising out of or caused, directly or indirectly, by circumstances beyond its reasonable control, including without limitation, acts of God; earthquakes; fires; floods; wars; civil or military disturbances; sabotage; epidemics; riots; interruptions, loss or malfunctions of utilities or computer service; acts of civil or military authority or governmental actions; it being understood that the Warrant Agent shall use its best efforts to resume performance as soon as practicable under the circumstances.

(i) Accounting. The Warrant Agent shall account promptly to the Company with respect to Warrants exercised and concurrently pay to the Company all moneys received by the Warrant Agent on behalf of the Company on the purchase of shares of Common Stock through the exercise of Warrants. The Warrant Agent shall advise the Company by telephone at

the end of each day on which a payment for the exercise of Warrants is received of the amount so deposited to such account. The Warrant Agent shall as soon as practicable confirm such telephone advice to the Company in writing.

(j) No Conflict. Subject to applicable law, the Warrant Agent and any stockholder, affiliate, 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 become pecuniarily interested in any transaction in which the Company may be interested, or contract with or lend money to the Company or otherwise act as fully and freely as though it were not Warrant Agent under this Agreement. Subject to applicable law, nothing herein shall preclude the Warrant Agent from acting in any other capacity for the Company or for any other Person.

(k) Resignation; Termination. The Warrant Agent may resign its duties and be discharged from all further duties and liabilities hereunder (except liabilities arising as a result of the Warrant Agent’s bad faith, gross negligence or willful misconduct) after giving thirty (30) days’ prior written notice to the Company. The Company may remove the Warrant Agent upon thirty (30) days’ written notice, and the Warrant Agent shall thereupon in like manner be discharged from all further duties and liabilities hereunder, except as have been caused by the Warrant Agent’s bad faith, gross negligence or willful misconduct. The Company shall cause to be mailed promptly (by first class mail, postage prepaid) to each registered holder of a Warrant at such holder’s last address as shown on the register of the Company, at the Company’s expense, a copy of such notice of resignation or notice of removal, as the case may be. Upon such resignation or removal the Company shall promptly appoint in writing a new warrant agent. If the Company shall fail to make such appointment within a period of ninety (90) days after it has been notified in writing of such resignation by the resigning Warrant Agent or after such removal, then the holder of any Warrant may apply to any court of competent jurisdiction for the appointment of a new 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. Any successor warrant agent, whether appointed by the Company or by such a court, shall be (i) a Person, organized under the laws of the United States or of any state thereof and authorized under such laws to conduct a shareholder services business, be subject to supervision and examination by Federal or state authority, and have a combined capital and surplus of not less than $100,000,000 as set forth in its most recent published annual report of condition; or (ii) an affiliate of such a Person described above. After acceptance in writing of such appointment by the new warrant agent it shall be vested with the same powers, rights, duties and responsibilities as if it had been originally named herein as the Warrant Agent, without any further assurance, conveyance, act or deed; but if for any reason it shall be necessary or expedient to execute and deliver any further assurance, conveyance, act or deed, the same shall be done at the expense of the Company and shall be legally and validly executed and delivered by the resigning or removed Warrant Agent. Not later than the effective date of any such appointment the Company shall file notice thereof with the resigning or removed Warrant Agent and shall forthwith cause a copy of such notice to be mailed (by first class, postage prepaid) to each registered holder of a Warrant at such holder’s last address as shown on the register of the Company. Failure to give any notice provided for in this Section 13(k), or any defect in any such notice, shall not affect the legality or validity of the resignation of the Warrant Agent or the appointment of a new warrant agent, as the case may be. The rights of the Warrant Agent under this Section 13 shall survive the Warrant Agent’s resignation or removal.

(l) Merger, Consolidation or Change of Name of Warrant Agent. Any corporation into which the Warrant Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Warrant Agent shall be a party, or any corporation succeeding to the all or substantially all of the agency business of the Warrant Agent or any new warrant agent shall be the successor to the Warrant Agent hereunder without the execution or filing of any document or any further act on the part of any of the parties hereto, provided that such corporation would be eligible for appointment as a successor Warrant Agent under the provisions of Section 13(k) above. If at the time such successor to the Warrant Agent shall succeed under this Agreement, any of the Warrant Certificates shall have been countersigned but not delivered, any such successor to the Warrant Agent may adopt the countersignature of the original Warrant Agent; and if at that time any of the Warrant Certificates shall not have been countersigned, any successor to the Warrant Agent may countersign such Warrant Certificates either in the name of the predecessor Warrant Agent or in the name of the successor Warrant Agent; and in all such cases such Warrant Certificates shall have the full force provided in the Warrant Certificates and in this Agreement. If at any time the name of the Warrant Agent shall be changed and at such time any of the Warrants shall have been countersigned but not delivered, the Warrant Agent whose name has changed may adopt the countersignature under its prior name; and if at that time any of the Warrants shall not have been countersigned, the Warrant Agent may countersign such Warrants either in its prior name or in its changed name; and in all such cases such Warrants shall have the full force provided in the Warrants and in this Agreement.

Section 14. Warrantholder Not Deemed a Stockholder. Prior to the exercise of the Warrants represented thereby no holder of a Warrant Certificate, as such, shall be entitled to any rights of a stockholder of the Company, including, but not limited to, the right to vote, to receive dividends or other distributions, to exercise any preemptive right or, except as otherwise expressly provided herein, 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.

Section 15. Notices to Company and Warrant Agent. All notices, requests or demands authorized by this Agreement to be given or made by the Warrant Agent or by any registered holder of any Warrant to or on the Company or the Warrant Agent to be effective shall be in writing (including by telecopy), and shall be deemed to have been duly given or made when delivered by hand, or two Business Days after being delivered to a recognized courier (whose stated terms of delivery are two business days or less to the destination of such notice), or five days after being deposited in the mail, or, in the case of telecopy notice, when received, addressed (until another address is filed in writing by the Company with the Warrant Agent) as follows:

In executing any such supplement or amendment, the Warrant Agent shall be entitled to receive and shall be fully protected in relying upon an opinion of counsel stating that such supplement or amendment is permitted or authorized by this Agreement. The Warrant Agent may, but shall not be obligated to, enter into any such supplement or amendment which affects the Warrant Agent’s own rights, duties or immunities under this Agreement.
