At such time as all beneficial interests in a particular Global Warrant have been exercised or exchanged for Definitive Warrants or a particular Global Warrant has been exercised, redeemed, repurchased or canceled in whole and not in part, each such Global Warrant shall be returned to or retained and canceled by the Warrant Agent in accordance with Section 3.8 hereof. At any time prior to such cancellation, if any beneficial interest in a Global Warrant is exercised or exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Warrant or for Definitive Warrants, the amount of Warrants represented by such Global Warrant shall be reduced accordingly and an endorsement shall be made on such Global Warrant by the Warrant Agent or by the Depositary at the direction of the Warrant Agent to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Warrant, such other Global Warrant shall be increased accordingly and an endorsement shall be made on such Global Warrant by the Warrant Agent or by the Depositary at the direction of the Warrant Agent to reflect such increase.

(iv) In connection with the due presentment for the registration of a transfer of any Warrant, the Warrant Agent and the Company may deem and treat the Person in whose name any Warrant is registered as the absolute owner of such Warrant for all purposes and neither the Warrant Agent nor the Company shall be affected by notice to the contrary.

If any mutilated Warrant is surrendered to the Warrant Agent or the Company and the Warrant Agent receives evidence to its satisfaction of the destruction, loss or theft of any Warrant, the Company shall issue and the Warrant Agent, upon receipt of a Warrant Countersignature Order, shall countersign a replacement Warrant if the Warrant Agent's requirements are met. If required by the Warrant Agent or the Company, an indemnity bond must be supplied by the holder that is sufficient in the judgment of the Warrant Agent and the Company to protect the Company, the Warrant Agent and any agent for purposes of the countersignature from any loss that any of them may suffer if a Warrant is replaced. The Company may charge for its expenses in replacing a Warrant. Every replacement Warrant is an additional warrant of the Company and shall be entitled to all of the benefits of this Warrant Agreement equally and proportionately with all other Warrants duly issued hereunder. 3.7. Temporary Warrants. Until certificates representing Warrants are ready for delivery, the Company may prepare and issue and the Warrant Agent, upon receipt of a Warrant Countersignature Order, shall countersign temporary Warrants. Temporary Warrants shall be substantially in the form of certificated Warrants but may have variations that the Company considers appropriate for temporary Warrants and that shall be reasonably acceptable to the Warrant Agent. Without -18- unreasonable delay, the Company shall prepare and the Warrant Agent shall countersign definitive Warrants in exchange for temporary Warrants. Holders of temporary Warrants shall be entitled to all of the benefits of this Warrant Agreement. 3.8. Cancellation. Subject to Section 3.5(g) hereof, the Company at any time may deliver Warrants to the Warrant Agent for cancellation.

The Warrant Agent and no one else shall cancel all Warrants surrendered for registration of transfer, exchange, exercise, replacement or cancellation and shall destroy canceled Warrants (subject to the record retention requirements of the Exchange Act). Certification of the destruction of all canceled Warrants shall be delivered to the Company. The Company may not issue new Warrants to replace Warrants that have been exercised or that have been delivered to the Warrant Agent for cancellation. Section 4. Separation of Warrants; Exercise of Warrants; Terms of Warrants. (a) The Notes and Warrants will not be separately transferable until the Separation Date. Subject to the terms of this Agreement, each Warrant holder shall have the right, which may be exercised during the period commencing at the opening of business on the Separation Date and until 5:00 p.m., New York City time on June 15, 2011 (the "Exercise Period"), to receive from the Company the number of fully paid and nonassessable Warrant Shares which the holder may at the time be entitled to receive on exercise of such Warrants and payment of the aggregate Exercise Price for all Warrant Shares being purchased (i) in cash, by wire transfer or by certified or official bank check payable to the order of the Company, (ii) by tendering Notes having a principal amount at the time of tender equal to the aggregate Exercise Price for all Warrant Shares being purchased, (iii) by tendering Warrants as set forth below or (iv) any combination of cash, Notes or Warrants. Each holder may elect, upon exercise of its Warrants during the Exercise Period, to receive Warrant Shares on a net basis, such that, without the exchange of any funds, the holder will receive such number of Warrant Shares as shall equal the product of (A) the number of Warrant Shares for which such Warrant is exercisable as of the date of exercise (if the Exercise Price were being paid in cash) and (B) the Cashless Exercise Ratio. The "Cashless Exercise Ratio" shall equal a fraction the numerator of which is the Market Value (as defined below) per share of Common Stock on the date of exercise minus the Exercise Price per share as of the date of exercise and the denominator of which is the Market Value per share on the date of exercise. Each Warrant not exercised prior to 5:00 p.m., New York City time, on June 15, 2011 (the "Expiration Date") shall become void and all rights thereunder and all rights in respect thereof under this Agreement shall cease as of such time. The Warrant Agent shall have no obligation to calculate the Cashless Exercise Ratio. The "Market Value" per share of Common Stock as of any date shall equal (i) if Common Stock is primarily traded on a securities exchange, the last sale price of such Common Stock on such securities exchange on the trading day immediately prior to the date of determination, or if no sale occurred on such day, the mean between the closing "bid" and -19- "asked" prices on such day, (ii) if the principal market for Common Stock is in the over-the-counter market, the closing sale price of such Common Stock on the trading day immediately prior to the date of the determination, as published by the National Association of Securities Dealers Automated Quotation System or similar organization, or if such price is not so published on such day, the mean between the closing "bid" and "asked" prices, if available, on such day, which prices may be obtained from any reputable pricing service, broker or dealer reasonably satisfactory to the Company, and (iii) if neither clause (i) nor clause (ii) is applicable, the fair market value on the date of determination of Common Stock as determined in good faith by the Board of Directors of the Company. (b) In order to exercise all or any of the Warrants represented by a Warrant Certificate, (i) in the case of a Definitive Warrant, the holder thereof must surrender upon exercise the Warrant Certificate to the Company at the corporate trust office of the Warrant Agent set forth in Section 15 hereof, (ii) in the case of a book-entry interest in a Global Warrant, the exercising Participant whose name appears on a securities position listing of the Depositary as the holder of such book-entry interest must comply with the Depositary's procedures relating to the exercise of such book-entry interest in such Global Warrant and (iii) in the case of interests in both Global Warrants and Definitive Warrants, the holder thereof or the Participant, as applicable, shall deliver to the Company at the corporate trust office of the Warrant Agent the form of election to purchase on the reverse thereof duly completed and signed, which signature shall be medallion guaranteed by an institution which is a member of a Securities Transfer Association recognized signature guarantee program, and upon payment to the Warrant Agent for the account of the Company of the Exercise Price, for the number of Warrant Shares in respect of which such Warrants are then exercised. Payment of the aggregate Exercise Price shall be made in accordance with Section 4(a) hereof. (c) Subject to the provisions of Section 5 hereof, upon compliance with clause (b) above, the Company shall deliver or cause to be delivered with all reasonable dispatch, to or to the written order of the holder and in such name or names as the holder may designate, a certificate or certificates for the number of whole Warrant Shares issuable upon the exercise of such Warrants or other securities or property to which such holder is entitled hereunder, together with cash as provided in Section 9 hereof; provided that if any consolidation, merger or lease or sale of assets is proposed to be effected by the Company or its subsidiaries as described in Section 8(k) hereof, or a tender offer or an exchange offer for shares of Common Stock shall be made, upon such surrender of Warrants and payment of the aggregate Exercise Price in accordance with Section 4(b) above, the Company shall, as soon as possible, but in any event not later than two business days thereafter, deliver or cause to be delivered the full number of Warrant Shares issuable upon the exercise of such Warrants in the manner described in this sentence or other securities or property to which such holder is entitled hereunder, together with cash as provided in Section 9 hereof. All certificates in this Section 4(c) shall be deemed to have been issued and any Person so designated to be named therein shall be deemed to have become a holder of record of such Warrant Shares as of the date of the surrender of such Warrants and payment of the aggregate Exercise Price. (d) The Warrants shall be exercisable, at the election of the holders thereof, either in full or from time to time in part. If less than all the Warrants represented by a Warrant -20- Certificate are exercised, such Warrant Certificate shall be surrendered and a new Warrant Certificate of the same tenor and for the number of Warrants which were not exercised shall be executed by the Company and delivered to the Warrant Agent and the Warrant Agent shall countersign the new Warrant Certificate, registered in such name or names as may be directed in writing by the holder, and shall deliver or cause to be delivered the new Warrant Certificate to the Person or Persons entitled to receive the same. (e) All Warrant Certificates surrendered upon exercise of Warrants shall be cancelled by the Warrant Agent. Such cancelled Warrant Certificates shall then be disposed of by the Warrant Agent in a manner satisfactory to the Company. The Warrant Agent shall report promptly to the Company with respect to Warrants exercised and concurrently pay to the Company all monies received by the Warrant Agent for the purchase of the Warrant Shares through the exercise of such Warrants. (f) The Warrant Agent shall keep copies of this Agreement and any notices given or received hereunder available for inspection by the holders during normal business hours at its office. The Company shall supply the Warrant Agent from time to time with such numbers of copies of this Agreement as the Warrant Agent may request. Section 5. Payment of Taxes. The Company shall pay all documentary stamp taxes attributable to the initial issuance of Warrant Shares upon the exercise of Warrants; provided that the Company shall not be required to pay any tax or taxes which may be payable in respect of any transfer involved in the issue of any Warrant Certificates or any certificates for Warrant Shares in a name other than that of the registered holder of a Warrant Certificate surrendered upon the exercise of a Warrant, and the Company shall not be required to issue or deliver such Warrant Certificates unless or until the Person or Persons requesting the issuance thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid. Section 6. Reservation of Warrant Shares; Registration of Warrant Shares. (a) The Company shall at all times reserve and keep available, free from preemptive rights, out of the aggregate of its authorized but unissued Common Stock and/or the authorized and issued Common Stock held in its treasury, for the purpose of enabling it to satisfy any obligation to issue Warrant Shares upon exercise of Warrants, the maximum number of shares of Common Stock which may then be deliverable upon the exercise of all outstanding Warrants. (b) The Company or, if appointed, the transfer agent for the Common Stock (the "Transfer Agent") and every subsequent transfer agent for any shares of the Company's capital stock issuable upon the exercise of any of the rights of purchase aforesaid will be irrevocably authorized and directed at all times to reserve such number of authorized shares as shall be required for such purpose. The Company shall keep a copy of this Agreement on file with the Transfer Agent and with every subsequent transfer agent for any shares of the Company's capital stock issuable upon the exercise of the rights of purchase represented by the Warrants. The Warrant Agent is hereby irrevocably authorized to requisition from time to time from such Transfer Agent the stock certificates required to honor outstanding Warrants upon exercise -21- thereof in accordance with the terms of this Agreement. The Company shall supply such Transfer Agent with duly executed certificates for such purposes and shall provide or otherwise make available any cash which may be payable as provided in Section 9 hereof. The Company shall furnish such Transfer Agent a copy of all notices of adjustments, and certificates related thereto, transmitted to each holder pursuant to Section 10 hereof. (c) Before or concurrently with taking any action which would cause an adjustment pursuant to Section 8 hereof to reduce the Exercise Price below the then par value (if any) of the Warrant Shares, the Company shall take any corporate action which may, in the opinion of its counsel (which may be counsel employed by the Company), be necessary in order that the Company may validly and legally issue fully paid and nonassessable Warrant Shares at the Exercise Price as so adjusted. (d) The Company covenants that all Warrant Shares which may be issued upon exercise of Warrants shall, upon issue, be fully paid, nonassessable, free of preemptive rights and free from all taxes, liens, charges and security interests with respect to the issuance thereof. Section 7. Obtaining Stock Exchange Listings. The Company shall from time to time take all action which may be necessary so that the Warrant Shares, immediately upon their issuance upon the exercise of Warrants, will be listed on a principal securities exchange, automated quotation system or other market within the United States of America, if any, on which other shares of Common Stock are then listed, if any. Section 8. Adjustment of Exercise Price and Number of Warrant Shares Issuable. The Exercise Price and the number of Warrant Shares issuable upon the exercise of each Warrant shall be subject to adjustment from time to time upon the occurrence of the events enumerated in this Section 8. Notwithstanding anything to the contrary in this Agreement, in no event shall the Exercise Price be less than the lower of the par value of the Common Stock or $0.01 per share of Common Stock. For purposes of this Section 8, "Common Stock" means shares now or hereafter authorized of any class of common shares of the Company however designated, that has the right (subject to any prior rights of any class or series of preferred stock) to participate in any distribution of the assets or earnings of the Company without limit as to per share amount. In addition to the adjustments required under this Section 8, the Company may, at any time reduce the Exercise Price to any amount greater than or equal to $0.01 per share for any period of time (but not less than 20 Business Days) deemed appropriate by the Board of Directors of the Company. (a) Adjustment for Change in Capital Stock. If the Company (i) pays a dividend or makes a distribution on its Common Stock payable in shares of its Common Stock, (ii) subdivides its outstanding shares of Common Stock into a greater number of shares, (iii) combines its outstanding shares of Common Stock into a smaller number of shares, (iv) makes a distribution on its Common Stock in shares of its capital stock other than Common Stock or (v) issues by reclassification of its Common Stock any shares of its capital stock, then the Exercise -22- Price in effect immediately prior to such action shall, subject to the second sentence of the first paragraph of this Section 8, be proportionately adjusted so that the holder of any Warrant exercised after such action may receive the aggregate number and kind of shares of capital stock of the Company which such holder would have owned immediately following such action assuming the exercise of such Warrant immediately prior to such action. The adjustment shall become effective immediately after the record date in the case of a dividend or distribution and immediately after the effective date in the case of a subdivision, combination or reclassification. If, after an adjustment pursuant to clause (v) above, a holder of a Warrant upon exercise of it may receive shares of two or more classes of capital stock of the Company, the Company shall determine, in good faith, the allocation of the adjusted Exercise Price between the classes of capital stock. After such allocation, the exercise privilege and the Exercise Price of each class of capital stock shall after such action be subject to adjustment on terms comparable to those applicable to Common Stock in this Section 8. Such adjustment shall be made successively whenever any event listed above shall occur. (b) Adjustment for Rights Issue. If the Company distributes any rights, options or warrants to all holders of its Common Stock entitling them for a period expiring within 45 days after the record date set forth below to subscribe for shares of Common Stock or securities convertible into, or exchangeable or exercisable for, shares of Common Stock, in either case, at a price per share less than the Fair Market Value (as defined in subsection (g) of this Section 8) per share on that record date, the Exercise Price shall be adjusted in accordance with the formula: O + N x P ----- E' = E x M ------------------------ O + N where: E' = the adjusted Exercise Price. E = the current Exercise Price. O = the number of shares of Common Stock outstanding on the record date. N = the number of additional shares of Common Stock issued pursuant to such rights, options or warrants. P = the price per share of the additional shares. M = the Fair Market Value per share of Common Stock on the record date. The adjustment shall be made successively whenever any such rights, options or warrants are issued and shall become effective immediately after the record date for the determination of stockholders entitled to receive the rights, options or warrants. If at the end of the period during which such rights, options or warrants are exercisable, not all rights, options or warrants shall -23- have been exercised, the Exercise Price shall be immediately readjusted to what it would have been if "N" in the above formula had been the number of shares actually issued. (c) Adjustment for Other Distributions. If the Company distributes to all holders of its Common Stock any of its assets (including cash), debt securities, preferred stock or any rights or warrants to purchase assets (including cash), debt securities, preferred stock or other securities of the Company, the Exercise Price shall be adjusted in accordance with the formula: E' = E x M - F ------------- M where: E' = the adjusted Exercise Price. E = the current Exercise Price. M = the Fair Market Value per share of Common Stock on the record date mentioned below. F = the fair market value on the record date of the debt securities, preferred stock, assets, securities, rights or warrants to be distributed in respect of one share of Common Stock as determined in good faith by the Board of Directors of the Company. The adjustment shall be made successively whenever any such distribution is made and shall become effective immediately after the record date for the determination of stockholders entitled to receive the distribution. This Section 8(c) shall not apply to cash dividends or other cash distributions paid out of consolidated current or retained earnings as shown on the books of the Company prepared in accordance with generally accepted accounting principles. In addition, this Section 8(c) shall not apply to rights, options or warrants referred to in Section 8(b) hereof. (d) Adjustment for Common Stock Issue. (i) If the Company issues shares of Common Stock for a consideration per share less than the Fair Market Value per share on the date the Company fixes the offering price of such additional shares, the Exercise Price shall be adjusted in accordance with the formula: E' = E x O + P/M ------------ A where: E' = the adjusted Exercise Price. E = the then current Exercise Price. -24- O = the number of shares outstanding immediately prior to the issuance of such additional shares. P = the aggregate consideration received for the issuance of such additional shares. M = the Fair Market Value per share on the date of issuance of such additional shares. A = the number of shares outstanding immediately after the issuance of such additional shares. The adjustment shall be made successively whenever any such issuance is made, and shall become effective immediately after such issuance. (ii) This Section 8(d) shall not apply to: (1) any of the transactions described in subsections (a), (b) and (c) of this Section 8, (2) the exercise of Warrants, (3) the conversion, exchange or exercise of other securities convertible into or exchangeable or exercisable for Common Stock the issuance of which convertible securities requires an adjustment to be made under Section 8(e), (4) the issuance of Common Stock (and options exercisable therefore) to employees, officers or directors of the Company or its subsidiaries under bona fide employee benefit plans adopted by the Board of Directors and approved by the holders of Common Stock when required by law, if such Common Stock would otherwise be covered by this Section 8(d) (but only to the extent that the aggregate number of shares excluded hereby and issued after the date of this Warrant Agreement shall not exceed 25% of the Common Stock outstanding at the time of the adoption of the most recent of such plans, exclusive of anti-dilution adjustments thereunder), (5) the issuance of Common Stock to shareholders or equity holders of any Person which merges into the Company, or with a subsidiary of the Company, in proportion to their stock or equity holdings of such Person immediately prior to such merger, upon such merger, provided that if such Person is an Affiliate of the Company, the Board of Directors, including a majority of the independent directors, shall have determined that the consideration received in such merger is fair to the Company from a financial point of view; provided further that if the Board of Directors shall not consist of at least one independent director who was not appointed, nominated or designated to the Board of Directors through any right of appointment, nomination or designation by an Affiliate of the Company, the Company shall have obtained a fairness opinion from a nationally recognized investment banking, appraisal or valuation firm which is not an Affiliate of the Company to the effect that the consideration received in such merger is fair to the Company from a financial point of view, -25- (6) the issuance of securities upon the conversion, exchange or exercise of other securities, warrants, options or similar rights if the conversion, exchange or exercise price is not less than the Fair Market Value per share of Common Stock at the time the security, warrant, option or right so converted, exchanged or exercised was issued or granted, or (7) the issuance of shares of Common Stock pursuant to rights, options or warrants which were originally issued in a Non-Affiliate Sale (as defined below) together with one or more other securities as part of a unit at a price per unit. (e) Adjustment for Convertible Securities Issue. If the Company issues any securities convertible into or exchangeable or exercisable for Common Stock (other than securities issued in transactions described in subsections (a), (b) and (c) of this Section 8 or excluded from the application of Section 8(d) pursuant to clause (ii) of Section 8(d)) for a consideration per share of Common Stock initially deliverable upon conversion, exchange or exercise of such securities less than the Fair Market Value per share on the date of issuance of such securities, the Exercise Price shall be adjusted in accordance with the formula: E' = E x O + P/M --------- O + D where: E' = the adjusted Exercise Price. E = the then current Exercise Price. O = the number of shares outstanding immediately prior to the issuance of such securities. P = the aggregate consideration received for the issuance of such securities. M = the Fair Market Value per share on the date of issuance of such securities. D = the maximum number of shares deliverable upon conversion or in exchange for such securities at the initial conversion, exchange or exercise rate. The adjustment shall be made successively whenever any such issuance is made, and shall become effective immediately after such issuance. If all of the Common Stock deliverable upon conversion, exchange or exercise of such securities have not been issued when such securities are no longer outstanding, then the Exercise Price shall promptly be readjusted to the Exercise Price which would then be in effect had the adjustment upon the issuance of such securities been made on the basis of the actual number of shares of Common Stock issued upon conversion, exchange or exercise of such securities. This subsection (e) shall not apply to warrants or other convertible securities issued to shareholders or equity holders of any Person which merges into the Company, or with a -26- subsidiary of the Company, in proportion to their stock or equity holdings of such person immediately prior to such merger, upon such merger, provided that if such Person is an Affiliate of the Company, the Board of Directors, including a majority of the independent directors, shall have determined that the consideration received in such merger is fair to the Company from a financial point of view; provided further that if the Board of Directors shall not consist of at least one independent director who was not appointed, nominated or designated to the Board of Directors through any right of appointment, nomination or designation by an Affiliate of the Company, the Company shall have obtained a fairness opinion from a nationally recognized investment banking, appraisal or valuation firm which is not an Affiliate of the Company to the effect that the consideration received in such merger is fair to the Company from a financial point of view. (f) Consideration Received. For purposes of any computation respecting consideration received pursuant to subsections (d) and (e) of this Section 8, the following shall apply: (1) in the case of the issuance of shares of Common Stock for cash, the consideration shall be the amount of such cash, provided that in no case shall any deduction be made for any commissions, discounts or other expenses incurred by the Company for any underwriting of the issue or otherwise in connection therewith; (2) in the case of the issuance of shares of Common Stock for a consideration in whole or in part other than cash, the consideration other than cash shall be deemed to be the fair market value thereof as determined in good faith by the Board of Directors (irrespective of the accounting treatment thereof), whose determination shall be conclusive and non-appealable, and described in a Board resolution which shall be filed with the Warrant Agent; (3) in the case of the issuance of securities convertible into or exchangeable or exercisable for shares, the aggregate consideration received therefor shall be deemed to be the consideration received by the Company for the issuance of such securities plus the additional minimum consideration, if any, to be received by the Company upon the conversion, exchange or exercise thereof (the consideration in each case to be determined in the same manner as provided in clauses (1) and (2) of this subsection (f)); and (4) in the case of the issuance of shares of Common Stock pursuant to rights, options or warrants which rights, options or warrants were originally issued together with one or more other securities as part of a unit at a price per unit, the consideration shall be deemed to be the fair value of such rights, options or warrants at the time of issuance thereof as determined in good faith by the Board of Directors whose determination shall be conclusive and non-appealable and described in a Board resolution which shall be filed with the Warrant Agent plus the additional consideration, if any, to be received by the Company upon the exercise, conversion or exchange thereof (as determined in the same manner as provided in clauses (1) and (2) of this subsection (f)). (g) Fair Market Value. For purposes of Sections 8 (b), (c), (d) and (e) hereof, the "Fair Market Value" per share of Common Stock at any date of determination shall be (1) in -27- connection with a sale by the Company to a party that is not an Affiliate of the Company in an arm's-length transaction (a "Non-Affiliate Sale"), the price per security at which such security is sold and (2) in connection with any sale by the Company to an Affiliate of the Company, (A) the last price per security at which such security was sold in a Non-Affiliate Sale within the three-month period preceding such date of determination and (B), if clause (A) is not applicable, the fair market value of such security determined in good faith by (i) a majority of the Board of Directors of the Company, including a majority of the Disinterested Directors, and approved in a Board resolution delivered to the Warrant Agent or (ii) a nationally recognized investment banking, appraisal or valuation firm, which is not an Affiliate of the Company, in each case, taking into account, among all other factors deemed relevant by the Board of Directors or such investment banking, appraisal or valuation firm, the trading price and volume of such security on any national securities exchange or automated quotation system on which such security is traded. For purposes of this Section 8(g), "Disinterested Director" means, in connection with any issuance of securities that gives rise to a determination of the Fair Market Value thereof, each member of the Board of Directors who is not an officer, employee, director or other Affiliate of the party to whom the Company is proposing to issue the securities giving rise to such determination. For purposes of this Section 8(g), "Affiliate" of any specified Person means (A) any other Person directly or indirectly controlling or controlled by or under direct or indirect common control with such specified Person and (B) any director or officer of such specified Person. For purposes of this definition "Control" (including, with correlative meanings, the terms "Controlling," "Controlled By" and "Under Common Control With") as used with respect to any Person, shall mean the possession, directly or indirectly, of the power to direct or cause the direction of the management or policies of such Person, whether through the ownership of voting securities, by agreement or otherwise. (h) When De Minimis Adjustment May Be Deferred. No adjustment in the Exercise Price need be made unless the adjustment would require an increase or decrease of at least 1% in the Exercise Price. Any adjustments that are not made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Section 8 shall be made to the nearest cent or to the nearest 1/100th of a share, as the case may be, it being understood that no such rounding shall be made under Section 8(p). (i) When No Adjustment Required. With respect to Warrants of any holder, no adjustment need be made for a transaction referred to Section 8(a), (b), (c), (d), (e) or (f) hereof, if such holder is to participate (without being required to exercise its Warrants) in the transaction on a basis and with notice that the Board of Directors determines to be fair and appropriate in light of the basis and notice on which holders of Common Stock participate in the transaction. No adjustment need be made for (i) rights to purchase Common Stock pursuant to a Company plan for reinvestment of dividends or interest or (ii) a change in the par value or no par value of the Common Stock. To the extent the Warrants become convertible into cash, no adjustment need be made thereafter as to the cash. Interest will not accrue on the cash. (j) Notice of Adjustment. Whenever the Exercise Price is adjusted, the Company shall provide the notices required by Section 10 hereof. -28- (k) Reorganization of Company. Immediately after the date hereof, if the Company consolidates or merges with or into, or transfers or leases all or substantially all its assets to, any Person, upon consummation of such transaction the Warrants shall automatically become exercisable for the kind and amount of securities, cash or other assets which the holder of a Warrant would have owned immediately after the consolidation, merger, transfer or lease if the holder had exercised the Warrant immediately before the consummation of the transaction. Concurrently with the consummation of such transaction, the corporation formed by or surviving any such consolidation or merger if other than the Company, or the Person to which such sale or conveyance shall have been made, shall enter into (i) a supplemental Warrant Agreement so providing and further providing for adjustments which shall be as nearly equivalent as may be practical to the adjustments provided for in this Section 8(k) and (ii) a supplement to the Equity Registration Rights Agreement providing for the assumption of the Company's obligations thereunder. The successor Company shall mail to Warrant holders a notice describing the supplemental Warrant Agreement and Equity Registration Rights Agreement. If the issuer of securities deliverable upon exercise of Warrants under the supplemental Warrant Agreement is an Affiliate of the formed, surviving, transferee or lessee corporation, such issuer shall join in the supplemental Warrant Agreement and Equity Registration Rights Agreement. If this Section 8(k) shall be applicable, Sections 8(a), (b), (c), (d), (e) and (f) hereof shall not be applicable. (l) Company Determination Final. Any determination that the Company or the Board of Directors must make pursuant to Section 8(a), (c), (d), (e), (f), (g), (h) or (i) hereof is conclusive and non-appealable. (m) Warrant Agent's Disclaimer. The Warrant Agent shall have no duty to determine when an adjustment under this Section 8 should be made, how it should be made or what it should be. The Warrant Agent shall have no duty to determine whether a supplemental Warrant Agreement under Section 8(k) need be entered into or whether any provisions of a supplemental Warrant Agreement under Section 8(k) hereof are correct. The Warrant Agent makes no representation as to the validity or value of any securities or assets issued upon exercise of Warrants. The Warrant Agent shall not be responsible for the Company's failure to comply with this Section 8. (n) When Issuance or Payment May Be Deferred. In any case in which this Section 8 shall require that an adjustment in the Exercise Price be made effective as of a record date for a specified event, the Company may elect to defer until the occurrence of such event (i) issuing to the holder of any Warrant exercised after such record date the Warrant Shares and other capital stock of the Company, if any, issuable upon such exercise over and above the Warrant Shares and other capital stock of the Company, if any, issuable upon such exercise on the basis of the Exercise Price and (ii) paying to such holder any amount in cash in lieu of a fractional share pursuant to Section 10 hereof; provided that the Company shall deliver to such holder a due bill or other appropriate instrument evidencing such holder's right to receive such additional Warrant Shares, other capital stock and cash upon the occurrence of the event requiring such adjustment. (o) Adjustment in Number of Shares. Upon each adjustment of the Exercise Price pursuant to this Section 8, each Warrant outstanding prior to the making of the adjustment in the Exercise Price shall thereafter evidence the right to receive upon payment of the adjusted -29- Exercise Price that number of shares of Common Stock (calculated to the nearest hundredth) obtained from the following formula: N' = N x E --- E' where: N' = the adjusted number of Warrant Shares issuable upon exercise of a Warrant by payment of the adjusted Exercise Price. N = the number or Warrant Shares previously issuable upon exercise of a Warrant by payment of the Exercise Price prior to adjustment. E' = the adjusted Exercise Price. E = the Exercise Price prior to adjustment. (p) Form of Warrants. Irrespective of any adjustments in the Exercise Price or the number or kind of shares purchasable upon the exercise of the Warrants, Warrants theretofore or thereafter issued may continue to express the same price and number and kind of shares as are stated in the Warrants initially issuable pursuant to this Agreement. Section 9. Fractional Interests. The Company shall not be required to issue fractional Warrant Shares on the exercise of Warrants. If more than one Warrant shall be presented for exercise in full at the same time by the same holder, the number of full Warrant Shares which shall be issuable upon the exercise thereof shall be computed on the basis of the aggregate number of Warrant Shares purchasable on exercise of the Warrants so presented. If any fraction of a Warrant Share would, except for the provisions of this Section 9, be issuable on the exercise of any Warrants (or specified portion thereof), the Company shall pay an amount in cash equal to the Fair Market Value per Warrant Share, as determined on the day immediately preceding the date the Warrant is presented for exercise, multiplied by such fraction, computed to the nearest whole U.S. cent. Section 10. Notices to Warrant Holders. (a) Upon any adjustment of the Exercise Price pursuant to Section 8 hereof, the Company shall promptly thereafter (i) cause to be filed with the Warrant Agent a certificate of a firm of independent public accountants of recognized standing selected by the Board of Directors of the Company (who may be the regular auditors of the Company) setting forth the Exercise Price after such adjustment and setting forth in reasonable detail the method of calculation and the facts upon which such calculations are based and setting forth the number of Warrant Shares (or portion thereof) issuable after such adjustment in the Exercise Price, upon exercise of a Warrant and payment of the adjusted Exercise Price, which certificate shall be conclusive evidence of the correctness of the matters set forth therein, and (ii) cause to be given to each of the registered holders of Warrants at the address appearing on the Warrant register for each such registered holder written notice of such adjustments by first-class mail, postage prepaid. Where -30- appropriate, such notice may be given in advance and included as a part of the notice required to be mailed under the other provisions of this Section 10. (b) In the event: (i) that the Company shall authorize the issuance to all holders of shares of Common Stock of rights, options or warrants to subscribe for or purchase shares of Common Stock or of any other subscription rights or warrants; (ii) that the Company shall authorize the distribution to all holders of shares of Common Stock of evidences of its indebtedness or assets (other than dividends or cash distributions paid out of consolidated current or retained earnings as shown on the books of the Company prepared in accordance with generally accepted accounting principles or dividends payable in shares of Common Stock or distributions); (iii) of any consolidation or merger to which the Company is a party and for which approval of any stockholders of the Company is required, or of the conveyance or transfer of the properties and assets of the Company substantially as an entirety, or of any reclassification or change of Common Stock issuable upon exercise of the Warrants (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 subdivision or combination), or a tender offer or exchange offer by the Company for shares of Common Stock; (iv) of the voluntary or involuntary dissolution, liquidation or winding up of the Company; or (v) that the Company proposes to take any action (other than actions of the character described in Section 8(a) hereof) which would require an adjustment of the Exercise Price pursuant to Section 8 hereof; then the Company shall cause to be filed with the Warrant Agent and shall cause to be given to each registered holder of Warrants at his address appearing on the Warrant register, at least 10 days prior to the applicable record date hereinafter specified, or promptly in the case of events for which there is no record date, by first-class mail, postage prepaid, a written notice stating (x) the date as of which the holders of record of shares of Common Stock to be entitled to receive any such rights, options, warrants or distribution are to be determined, (y) the initial expiration date set forth in any tender offer or exchange offer for shares of Common Stock, or (z) the date on which any such consolidation, merger, conveyance, transfer, dissolution, liquidation or winding up is expected to become effective or consummated, and the date as of which it is expected that holders of record of shares of Common Stock shall be entitled to exchange such shares for securities or other property, if any, deliverable upon such reclassification, consolidation, merger, conveyance, transfer, dissolution, liquidation or winding up. The failure to give the notice required by this Section 10 or any defect therein shall not affect the legality or validity of any distribution, right, option, warrant, consolidation, merger, conveyance, transfer, dissolution, liquidation or winding up, or the vote upon any action. -31- (c) Nothing contained in this Agreement or in any of the Warrant Certificates shall be construed as conferring upon the holders of Warrants the right to vote or to consent or to receive notice as stockholders in respect of the meetings of stockholders or the election of directors of the Company or any other matter, or any rights whatsoever as stockholders of the Company. Section 11. Merger, Consolidation or Change of Name of Warrant Agent. (a) Any corporation into which the Warrant Agent may be merged or with which it may be consolidated, or any corporation resulting from any merger or consolidation to which the Warrant Agent shall be a party, or any corporation succeeding to the business of the Warrant Agent, shall be the successor to the Warrant Agent hereunder without the execution or filing of any paper 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 hereof. In case at the time such successor to the Warrant Agent shall succeed to the agency created by this Agreement, and in case at that time 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 in case 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 to the Warrant Agent; and in all such cases such Warrant Certificates shall have the full force and effect provided in the Warrant Certificates and in this Agreement. (b) In case at any time the name of the Warrant Agent shall be changed and at such time any of the Warrant Certificates shall have been countersigned but not delivered, the Warrant Agent whose name has been changed may adopt the countersignature under its prior name, and in case at that time any of the Warrant Certificates shall not have been countersigned, the Warrant Agent may countersign such Warrant Certificates either in its prior name or in its changed name, and in all such cases such Warrant Certificates shall have the full force and effect provided in the Warrant Certificates and in this Agreement. Section 12. Warrant Agent. The Warrant Agent undertakes the duties and obligations imposed by this Agreement upon the following terms and conditions, by all of which the Company and the holders of Warrants, by their acceptance thereof, shall be bound: (a) The statements contained herein and in the Warrant Certificates shall be taken as statements of the Company and the Warrant Agent assumes no responsibility for the correctness of any of the same except such as describe the Warrant Agent or action taken or to be taken by it. The Warrant Agent assumes no responsibility with respect to the distribution of the Warrant Certificates except as herein otherwise provided. (b) The Warrant Agent shall not 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. -32- (c) The Warrant Agent may consult at any time with counsel satisfactory to it (who may be counsel for the Company) and the Warrant Agent shall incur no liability or responsibility to the Company or to any holder of any Warrant Certificate in respect of any action taken, suffered or omitted by it hereunder in good faith and in accordance with the opinion or the advice of such counsel. (d) The Warrant Agent shall incur no liability or responsibility to the Company or to any holder of any Warrant Certificate for any action taken in reliance on any Warrant Certificate, certificate of shares, notice, resolution, waiver, consent, order, certificate, or other paper, document or instrument believed by it to be genuine and to have been signed, sent or presented by the proper party or parties. (e) 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 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 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, bad faith or breach of this Agreement. The Warrant Agent shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Warrant Agent to so notify the Company shall not relieve the Company of its obligations hereunder. The Company shall defend the claim and the Warrant Agent shall cooperate in the defense. The Warrant Agent may have separate counsel and the Company shall pay the reasonable fees and expenses of such counsel. The Company need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld, conditioned or delayed. (f) The Warrant Agent shall be under no obligation to institute any action, suit or legal proceeding or to take any other action likely to involve expense unless the Company or one or more registered holders of Warrants shall furnish the Warrant Agent with reasonable security and indemnity for any costs and expenses which may be incurred, but this provision shall not affect the power of the Warrant Agent to take such action as it may consider proper, whether with or without any such security or indemnity. All rights of action under this Agreement or under any of the Warrants may be enforced by the Warrant Agent without the possession of any of the Warrant Certificates or the production thereof at any trial or other proceeding relative thereto, and any such action, suit or proceeding instituted by the Warrant Agent shall be brought in its name as Warrant Agent and any recovery of judgment shall be for the ratable benefit of the registered holders of the Warrants, as their respective rights or interests may appear. (g) The Warrant Agent, and any stockholder, director, officer or employee of it, may buy, sell or deal in any of the Warrants or other securities of the Company or -33- 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. Nothing herein shall preclude the Warrant Agent from acting in any other capacity for the Company or for any other legal entity. (h) The Warrant Agent shall act hereunder solely as agent for the Company, and its duties shall be determined solely by the provisions hereof. The Warrant Agent shall not be liable for anything which it may do or refrain from doing in connection with this Agreement except for its own gross negligence, bad faith or breach of this Agreement. (i) The Warrant Agent shall not at any time be under any duty or responsibility to any holder of any Warrant Certificate to make or cause to be made any adjustment of the Exercise Price or number of the Warrant Shares or other securities or property deliverable as provided in this Agreement, or to determine whether any facts exist which may require any of such adjustments, or with respect to the nature or extent of any such adjustments, when made, or with respect to the method employed in making the same. The Warrant Agent shall not be accountable with respect to the validity or value or the kind or amount of any Warrant Shares or of any securities or property which may at any time be issued or delivered upon the exercise of any Warrant or with respect to whether any such Warrant Shares or other securities will when issued be validly issued and fully paid and nonassessable, and makes no representation with respect thereto. (j) The Warrant Agent shall not be required to risk or expend its own funds on the performance of it obligations and duties hereunder. (k) The obligations of the Company under this Section 12 shall survive the exercise and the expiration of the Warrant Certificates and the resignation and removal of the Warrant Agent. (l) The Warrant Agent shall not be under any liability for interest on, and shall not be required to invest, any monies at any time received by it pursuant to any of the provisions of this Agreement or of the Warrant Certificates. (m) Any corporation or bank into which the Warrant Agent hereunder may be merged or converted, or any corporation or bank with which the Warrant Agent may be consolidated, or any corporation or bank resulting from any merger, conversion or consolidation to which the Warrant Agent shall be a party, or any corporation or bank to which the Warrant Agent shall sell or otherwise transfer all or substantially all of its corporate trust business, shall be the successor to the Warrant Agent under this Agreement (provided that such corporation or bank shall be qualified as aforesaid) without the execution or filing of any document or any further act on the part of any of the parties hereto. (n) No Warrant Agent under this Agreement shall be personally liable for any action or omission of any successor Warrant Agent. -34- Section 13. Change of Warrant Agent. If the Warrant Agent shall resign or become incapable of acting as Warrant Agent, the Company shall appoint a successor to such Warrant Agent. If the Company shall fail to make such appointment within a period of 30 days after it has been notified in writing of such incapacity by the Warrant Agent or by the registered holder of a Warrant Certificate, then the registered holder of any Warrant may apply to any court of competent jurisdiction for the appointment of a successor to the Warrant Agent. Pending appointment of a successor to such Warrant Agent, either by the Company or by such a court, the duties of the Warrant Agent shall be carried out by the Company. The holders of a majority of the unexercised Warrants shall be entitled at any time to remove the Warrant Agent and appoint a successor to such Warrant Agent. Such successor to the Warrant Agent need not be approved by the Company or the former Warrant Agent. After appointment the successor to the Warrant Agent shall be vested with the same powers, rights, duties and responsibilities as if it had been originally named as Warrant Agent without further act or deed; provided that the former Warrant Agent shall deliver and transfer to the successor to the Warrant Agent any property at the time held by it hereunder and execute and deliver any further assurance, conveyance, act or deed necessary for the purpose. Failure to give any notice provided for in this Section 13, however, or any defect therein, shall not affect the legality or validity of the appointment of a successor to the Warrant Agent. Section 14. Reports. (a) The Company agrees with each holder, for so long as any Warrants or Warrant Shares remain outstanding and during any period in which the Company (i) is not subject to Section 13 or 15(d) of the Exchange Act, to make available, upon request of any holder, to such holder or beneficial owner of Warrants or Warrant Shares in connection with any sale thereof and any prospective purchaser of such Warrants or Warrant Shares designated by such holder or beneficial owner, the information required by Rule 144(A)(d)(4) under the Act in order to permit resales of such Warrants or Warrant Shares pursuant to Rule 144A, and (ii) is subject to Section 13 or 15(d) of the Exchange Act, to make all filings required thereby in a timely manner in order to permit resales of such Warrants or Warrant Shares pursuant to Rule 144A. (b) The Company shall provide the Warrant Agent with a sufficient number of copies of all such reports that the Warrant Agent may be required to deliver to the holders of the Warrants and the Warrant Shares under this Section 14.
