This Warrant amends and restates that certain warrant that was issued on April 2, 2002 (the "Issuance Date") pursuant to the Main Agreement, is subject to the terms and conditions thereof and the holder of this Warrant (the "Holder") is subject to certain restrictions set forth in the Main Agreement and shall be entitled to certain rights and privileges set forth in the Main Agreement. This Warrant is the Warrant referred to as the "Warrant" in the Main Agreement. Capitalized terms used but not otherwise defined herein shall have the meanings ascribed to them in the Main Agreement. A copy of the Main Agreement may be obtained by the registered Holder hereof upon written request to the Issuer. 1. Exercise of Warrant. 1.1 Manner of Exercise. This Warrant may be exercised by the Holder hereof, in whole or in part, but not for less than 250,000 shares of Common Stock appearing on the face of this Warrant at a time (or such lesser number of shares which may then constitute the maximum number purchasable), at any time and from time to time, on any Business Day, by facsimile, mail or overnight courier delivery of a notice in substantially the form attached to this Warrant (or a reasonable facsimile thereof) duly executed by such Holder (a "Warrant Exercise Notice"). The closing of each exercise shall take place (i) on the second (2nd) Business Day following, and excluding, the date the Warrant Exercise Notice is delivered (the "Warrant Notice Date"), (ii) at the option of the Holder, such later date as the conditions set forth in Section 1.2 have been waived or satisfied or (iii) any other date upon which the exercising Holder and the Issuer mutually agree (each, a "Warrant Closing Date") unless the Holder shall have withdrawn the Warrant Exercise Notice prior to the closing of such exercise on such Warrant Closing Date by written notice to the Issuer regardless of whether such conditions have been waived or satisfied. 1 Exhibit 4.21 (a) This Warrant may be exercised on a net exercise basis only. The number of shares of Common Stock that the Issuer shall issue shall be computed as of the date of the Warrant Exercise Notice using the following formula: X = (N*Y/B)*(A-B)/A Where: X = the number of shares to be issued to the Holder hereof; N = the number of shares on the face of this Warrant, not to exceed in the aggregate the Issuable Number, for which this Warrant is being exercised as specified in the Warrant Exercise Notice; Y = the Stock Purchase Price; A = the Daily Market Price of one share of the Common Stock issuable at the date of such calculation; and B = the Warrant Price (as defined below) (as adjusted to the date of such calculation). 1.2 Conditions to Closing. It shall be a condition of the exercising Holder's obligation to close on each Warrant Closing Date that each of the following are satisfied, unless waived by such Holder: (a) (1) the representations and warranties made by the Issuer in the Main Agreement shall be true and correct as of such Warrant Closing Date, except those representations and warranties that address matters only as of a particular date, which shall be true and correct as of such date; (2) the Issuer shall have complied fully with all of the covenants and agreements in the Main Agreement; (3) all shares to be issued upon such exercise shall be registered under the Securities Act in accordance with the terms of the Main Agreement, shall be freely tradable Registered Common Stock and shall be duly listed and admitted to trading on the New York Stock Exchange, American Stock Exchange or Nasdaq National Market System in accordance with the terms of the Main Agreement (unless, with respect to clause (3) only, the Holder expressly consents in writing to the issuance of unregistered Common Stock for a portion or all of the shares to be issued upon such exercise; in such case, the Issuer shall use its best efforts to cause to be satisfied this condition in clause (3) for the balance of shares to be issued upon such exercise); and such Holder shall have received a certificate of the Chief Executive Officer or the Chief Financial Officer of the Issuer dated such date and to the effect of clauses (1), (2) and (3). (b) On such Warrant Closing Date, the Issuer shall have delivered to the Holder an opinion of Dykema Gossett PLLC (or such other counsel reasonably 2 Exhibit 4.21 satisfactory to such Holder) reasonably satisfactory to such Holder, dated the date of delivery, confirming in substance the matters covered in paragraphs (a), (b), (c), (d), (e), (f), and subsection (i) of (g) of Section 4 of the Main Agreement and to the effect that the offer and sale of such Registered Common Stock (as defined below) to such Holder do not require registration under the Securities Act. (c) The issuance of Common Stock shall not cause the Issuer to exceed the Maximum Number (as defined in the Main Agreement). (d) As of such Warrant Closing Date, the Issuer shall have delivered to the Holder all Restatement Notices required to be delivered following a Restatement, and no Restatement shall have occurred on or after the date on which the Warrant Exercise Notice is delivered. The Issuer shall use its best efforts to cause each of the foregoing conditions to be satisfied at the earliest possible date. If the condition set forth above in paragraph (a)(3) of this Section 1.2 is not satisfied, (x) Holder shall be entitled to all remedies available at law or in equity in respect of the Issuer's failure to issue all of the Registered Common Stock required to be issued pursuant to this Section 1, and (y) the Issuer, upon the written demand, from time to time, of Holder, shall issue unregistered Common Stock for a portion or all of the shares of Common Stock to be issued as set forth in such written demand and shall use its best efforts to cause such condition to be satisfied. In such cases, upon satisfaction of the condition set forth in the above paragraph (a)(3), the Issuer shall deliver written notice to such Holder of such satisfaction. If such condition is not satisfied or waived prior to the second (2nd) Business Day following, and excluding, the date the Warrant Exercise Notice is delivered, then (x) the Holder may, at its sole option, and at any time, withdraw the Warrant Exercise Notice by written notice to the Issuer regardless of whether such condition has been satisfied or waived as of the withdrawal date and, after such withdrawal, shall have no further obligations with respect to such Warrant Exercise Notice and may submit a Warrant Exercise Notice on any future date with respect to the shares referenced in the original Warrant Exercise Notice; provided, however, that if Holder shall not have withdrawn a Warrant Exercise Notice by written notice delivered by the corresponding Warrant Closing Date, then the Issuer shall place in escrow by 5 p.m., New York City time, on such Warrant Closing Date an amount of cash equal to one hundred four percent (104%) of the product of (x) the number of shares of Registered Common Stock due under this Section 1 multiplied by (y) the Daily Market Price calculated as of such Warrant Notice Date. If such condition is not satisfied within sixty (60) calendar days after and including such Warrant Closing Date, the Issuer shall cause the escrow agent to deliver such cash to Holder in lieu of the Issuer 's obligations to issue stock upon such exercise of the Warrant; provided, however, that the Holder shall not be obligated to pay any consideration to exercise the Warrant in order to receive the cash payment specified immediately above; provided, further, however, that this Warrant shall be deemed exercised with respect to such number of shares of Registered Common Stock as was the subject of such Warrant Exercise Notice and due to be issued under this Section 1. 1.3 When Exercise Effective. Each exercise of this Warrant shall be deemed to have been effected immediately prior to 6:30 p.m. (time in effect in New York City on such date) on the Business Day on which the Warrant Exercise Notice is delivered as provided in Section 1.1, and at such time the Person or Persons in whose name or names any certificate or certificates 3 Exhibit 4.21 for shares of Common Stock (or Other Securities) shall be issuable upon such exercise as provided in Section 1.4 shall be deemed to have become the Holder or Holders of record thereof; provided, however, that such exercise shall not be deemed effective if at or prior to 6:30 p.m. (time in effect in New York City on such date) on the Warrant Closing Date the Holder delivers written notice of withdrawal to the Issuer as set forth in Section 1.2. 1.4 Delivery of Warrant. On the Warrant Closing Date, the registered Holder shall surrender this Warrant Certificate to the Issuer at the address set forth for notices to the Issuer in Section 20 of the Main Agreement and such Holder shall thereupon be entitled to receive the number of duly authorized, validly issued, fully paid and nonassessable shares of Common Stock (or Other Securities) determined as provided in Section 1.1 hereof. 1.5 Delivery of Stock Certificates, etc. On a Warrant Closing Date, the Issuer at its expense (including the payment by it of any applicable issue taxes) shall cause to be issued in the name of and delivered to the Holder hereof or as such Holder may direct, (a) via facsimile and at such address specified by the Holder via a reputable overnight courier, a delivery notice in the form of Exhibit 2 hereto and one or more certificates for the number of duly authorized, validly issued, fully paid and nonassessable shares of Common Stock (or Other Securities) to which such Holder shall be entitled upon such exercise plus, in lieu of any fractional share to which such Holder would otherwise be entitled, cash in an amount equal to the same fraction of the Daily Market Price per share on the Business Day next preceding the date of such exercise, and (b) in case such exercise is in part only, at such address specified by the Holder via reputable overnight courier, a new Warrant of like tenor, calling in the aggregate on the face or faces thereof for the number of shares of Common Stock equal (without giving effect to any adjustment thereof) to the number of such shares called for on the face of this Warrant minus the number of such shares designated by the Holder in the Warrant Exercise Notice upon such exercise as provided in Section 1.1. 2. Adjustment of Common Stock Issuable Upon Exercise. 2.1 General; Warrant Price. The "Warrant Price" shall initially equal the Stock Purchase Price described in Section 12.21. The Warrant Price shall thereafter be adjusted and readjusted from time to time as provided in Sections 2, 3 and 4 hereof and, as so adjusted or readjusted, shall remain in effect until a further adjustment or readjustment thereof is required by Sections 2, 3 and 4 hereof. Additionally, the Warrant Price shall increase by seventy-five cents ($0.75) on each anniversary of the date of the Main Agreement and each such increase shall be adjusted and readjusted as if such increase had occurred on the date of the Main Agreement and had subsequently been adjusted and readjusted as provided in Sections 2, 3 and 4 hereof. 2.2 Adjustment of Warrant Price. (a) Issuance of Additional Shares of Common Stock. In case the Issuer at any time or from time to time after the date hereof shall issue or sell Additional Shares of Common Stock (including Additional Shares of Common Stock deemed to be issued 4 Exhibit 4.21 pursuant to Section 2.3 or 2.4) without consideration or for a consideration per share less than the Warrant Price in effect immediately prior to such issue or sale, then, and in each such case, subject to Section 2.8, such Warrant Price shall be reduced, concurrently with such issue or sale, to a price (calculated to the nearest .001 of a cent) determined by multiplying such Warrant Price by a fraction; (i) the numerator of which shall be (1) the number of shares of Common Stock outstanding immediately prior to such issue or sale (on a fully-diluted basis calculated using the treasury method in accordance with generally accepted accounting principles) plus (2) the number of shares of Common Stock which the aggregate consideration received or to be received by the Issuer for the total number of such Additional Shares of Common Stock so issued or sold would purchase at such Warrant Price, and (ii) the denominator of which shall be the number of shares of Common Stock outstanding immediately after such issue or sale (on a fully-diluted basis calculated using the treasury method in accordance with generally accepted accounting principles), provided that, for the purposes of this Section 2.2(a) (x) immediately after any Additional Shares of Common Stock are deemed to have been issued pursuant to Section 2.3 or 2.4, such Additional Shares of Common Stock shall be deemed to be outstanding, and (y) treasury shares shall not be deemed to be outstanding. (b) Dividends and Distributions. In case the Issuer at any time or from time to time after the date hereof shall declare, order, pay or make a dividend or other distribution (including, without limitation, any distribution of other or additional stock or other securities or property or Options by way of dividend or spin-off, reclassification, recapitalization or similar corporate rearrangement) on the Common Stock, other than a dividend payable in Additional Shares of Common Stock, then, subject to Section 2.8, provision shall be made so that the Holder shall receive upon exercise hereof in addition to the number of shares of Common Stock receivable thereupon, the kind and amount of securities, cash or other property which the Holder would have been entitled to receive had the Holder held the Gross Number of shares of Common Stock with respect to such exercise on the date of such dividend record date and had the Holder thereafter, during the period from the date of such dividend to and including the date of exercise, retained such securities, cash or other property receivable by the Holder as aforesaid during such period, giving application to all adjustments called for during such period under this Warrant. 2.3 Treatment of Options and Convertible Securities. In case the Issuer at any time or from time to time after the date hereof shall issue, sell, grant or assume, or shall fix a record date for the determination of Holders of any class of securities entitled to receive, any Options or Convertible Securities (other than Options or Convertible Securities that constitute Excluded Securities), then, and in each such case, the maximum number of Additional Shares of Common 5 Exhibit 4.21 Stock (as set forth in the instrument relating thereto, without regard to any provisions contained therein for a subsequent adjustment of such number) issuable upon the exercise of such Options or, in the case of Convertible Securities and Options therefor, the conversion or exchange of such Convertible Securities, shall be deemed to be Additional Shares of Common Stock issued as of the time of such issue, sale, grant or assumption or, in case such a record date shall have been fixed, as of the close of business on such record date (or, in the case of Options or Convertible Securities with terms described in Section 2.3(b), the date of any change, increase or decrease described in Section 2.3(b)) (or, if the Common Stock trades on an ex-dividend basis, on the date prior to the commencement of ex-dividend trading), provided that such Additional Shares of Common Stock shall not be deemed to have been issued unless the consideration per share (determined pursuant to Section 2.5) of such shares would be less than the Warrant Price in effect on the date of and immediately prior to such issue, sale, grant or assumption or immediately prior to the close of business on such record date (or, if the Common Stock trades on an ex-dividend basis, on the date prior to the commencement of ex-dividend trading), as the case may be, and provided, further, that in any such case in which Additional Shares of Common Stock are deemed to be issued (a) no further adjustment of the Warrant Price shall be made upon the subsequent issue or sale of Convertible Securities or shares of Common Stock upon the exercise of such Options or the conversion or exchange of such Convertible Securities; (b) if such Options or Convertible Securities by their terms provide, with the passage of time or otherwise, for any change in the consideration payable to the Issuer, or increase or decrease in the number of Additional Shares of Common Stock issuable, upon the exercise, conversion or exchange thereof (by change of rate or otherwise), the Warrant Price computed upon the original issue, sale, grant or assumption thereof (or upon the occurrence of the record date, or date prior to the commencement of ex-dividend trading, as the case may be, with respect thereto), and any subsequent adjustments based thereon, shall, upon any such increase or decrease becoming effective, be recomputed to reflect such increase or decrease insofar as it affects such Options, or the rights of conversion or exchange under such Convertible Securities, which are outstanding at such time; (c) upon the expiration (or purchase by the Issuer and cancellation or retirement) of any such Options which shall not have been exercised or the expiration of any rights of conversion or exchange under any such Convertible Securities which (or purchase by the Issuer and cancellation or retirement of any such Convertible Securities the rights of conversion or exchange under which) shall not have been exercised, the Warrant Price computed upon the original issue, sale, grant or assumption thereof (or upon the occurrence of the record date, or date prior to the commencement of ex-dividend trading, as the case may be, with respect thereto), and any subsequent adjustments based thereon, shall, upon such expiration (or such purchase by the Issuer and cancellation or retirement, as the case may be), be recomputed as if: (i) in the case of Options for Common Stock or Convertible Securities, the only Additional Shares of Common Stock issued or sold were the Additional Shares of Common Stock, if any, actually issued or 6 Exhibit 4.21 sold upon the exercise of such Options or the conversion or exchange of such Convertible Securities and the consideration received therefor was the consideration actually received by the Issuer for the issue, sale, grant or assumption of all such Options, whether or not exercised, plus the consideration actually received by the Issuer upon such exercise, or for the issue or sale of all such Convertible Securities which were actually converted or exchanged, plus the additional consideration, if any, actually received by the Issuer upon such conversion or exchange, and (ii) in the case of Options for Convertible Securities, only the Convertible Securities, if any, actually issued or sold upon the exercise of such Options were issued at the time of the issue, sale, grant or assumption of such Options, and the consideration received by the Issuer for the Additional Shares of Common Stock deemed to have then been issued was the consideration actually received by the Issuer for the issue, sale, grant or assumption of all such Options, whether or not exercised, plus the consideration deemed to have been received by the Issuer (pursuant to Section 2.5) upon the issue or sale of such Convertible Securities with respect to which such Options were actually exercised; (d) no readjustment pursuant to subdivision (b) or (c) above shall have the effect of increasing the Warrant Price by an amount in excess of the amount of the adjustment thereof originally made in respect of the issue, sale, grant or assumption of such Options or Convertible Securities; and (e) in the case of any such Options which expire by their terms not more than 30 days after the date of issue, sale, grant or assumption thereof, no adjustment of the Warrant Price shall be made until the expiration or exercise of all such Options, whereupon such adjustment shall be made in the manner provided in subdivision (c) above. 2.4 Treatment of Stock Dividends, Stock Splits, etc. In case the Issuer at any time or from time to time after the date hereof shall declare or pay any dividend on the Common Stock payable in Common Stock, or shall effect a subdivision of the outstanding shares of Common Stock into a greater number of shares of Common Stock (by reclassification or otherwise than by payment of a dividend in Common Stock), then, and in each such case, Additional Shares of Common Stock shall be deemed to have been issued (a) in the case of any such dividend, immediately after the close of business on the record date for the determination of Holders of any class of securities entitled to receive such dividend, or (b) in the case of any such subdivision, at the close of business on the day immediately prior to the day upon which such corporate action becomes effective. 2.5 Computation of Consideration. For the purposes of this Section 2: 7 Exhibit 4.21 (a) the consideration for the issue or sale of any Additional Shares of Common Stock shall, irrespective of the accounting treatment of such consideration, (i) insofar as it consists of cash, be computed at the amount of cash received by the Issuer plus any expenses paid or incurred by the Issuer or any commissions or compensations paid or discounts or concessions allowed to underwriters, dealers or others performing similar services in connection with such issue or sale, (ii) insofar as it consists of property (including securities) other than cash, be computed at the fair value thereof at the time of such issue or sale, as determined in good faith by an independent appraisal firm of recognized national standing appointed by the Issuer, and (iii) in case Additional Shares of Common Stock are issued or sold together with other stock or securities or other assets of the Issuer for a consideration which covers both, be the portion of such consideration so received, computed as provided in clauses (i) and (ii) above, allocable to such Additional Shares of Common Stock, as determined in good faith by an independent appraisal firm of recognized national standing appointed by the Issuer. (b) Additional Shares of Common Stock deemed to have been issued pursuant to Section 2.3, relating to Options and Convertible Securities, shall be deemed to have been issued for a consideration per share determined by dividing (i) the total amount, if any, received and receivable by the Issuer as consideration for the issue, sale, grant or assumption of the Options or Convertible Securities in question, plus the minimum aggregate amount of additional consideration (as set forth in the instruments relating thereto, without regard to any provision contained therein for a subsequent adjustment of such consideration to protect against dilution) payable to the Issuer upon the exercise in full of such Options or the conversion or exchange of such Convertible Securities or, in the case of Options for Convertible Securities, the exercise of such Options for Convertible Securities and the conversion or exchange of such Convertible Securities, in each case computing such consideration as provided in the foregoing subdivision (a), by (ii) the maximum number of shares of Common Stock (as set forth in the instruments relating thereto, without regard to any provision contained therein for a subsequent adjustment of such number to protect against dilution) issuable upon the exercise of such Options or the conversion or exchange of such Convertible Securities (including the full 8 Exhibit 4.21 conversion or exchange of all Options and Convertible Securities underlying such Options and Convertible Securities); and (c) Additional Shares of Common Stock deemed to have been issued pursuant to Section 2.4, relating to stock dividends, stock splits, etc., shall be deemed to have been issued for no consideration. 2.6 Adjustments for Combinations, etc. In case the outstanding shares of Common Stock shall be combined or consolidated, by reclassification or otherwise, into a lesser number of shares of Common Stock, the Warrant Price in effect immediately prior to such combination or consolidation shall, concurrently with the effectiveness of such combination or consolidation, be proportionately increased. 2.7 Dilution in Case of Other Securities. In case any Other Securities shall be issued or sold or shall become subject to issue or sale upon the conversion or exchange of any stock (or Other Securities) of the Issuer (or any issuer of Other Securities or any other Person referred to in Section 3) or to subscription, purchase or other acquisition pursuant to any Options issued or granted by the Issuer (or any such other issuer or Person) for a consideration such as to dilute, on a basis consistent with the standards established in the other provisions of this Section 2, the purchase rights granted by this Warrant, then, and in each such case, the computations, adjustments and readjustments provided for in this Section 2 with respect to the Warrant Price shall be made as nearly as possible in the manner so provided and applied to determine the amount of Other Securities from time to time receivable upon the exercise of the Warrant, so as to protect the Holder or Holders of the Warrant against the effect of such dilution. 2.8 Minimum Adjustment of Warrant Price. If the amount of any adjustment of the Warrant Price required pursuant to this Section 2 would be less than one tenth (1/10) of one percent (1%) of the Warrant Price in effect at the time such adjustment is otherwise so required to be made, such amount shall be carried forward and adjustment with respect thereto made at the time of and together with any subsequent adjustment which, together with such amount and any other amount or amounts so carried forward, shall aggregate at least one tenth (1/10) of one percent (1%) of such Warrant Price. 3. Business Combinations. 3.1 Adjustment upon Business Combination. In case the Issuer after the date of the Main Agreement is party to (i) any acquisition of the Issuer by means of merger or other form of corporate reorganization in which outstanding shares of the Issuer are exchanged for securities or other consideration issued, or caused to be issued, by the Acquiring Person or its Parent, Subsidiary or affiliate, (ii) a sale of all or substantially all of the assets of the Issuer (on a consolidated basis) in a single transaction or series of related transactions, (iii) any other transaction or series of related transactions by the Issuer in which the power to cast the majority of the eligible votes at a meeting of the Issuer's shareholders at which directors are elected is transferred to a single entity or group acting in concert, or (iv) a capital reorganization or reclassification of the Common Stock or Other Securities (other than a reorganization or reclassification in which the Common Stock or Other Securities are not converted into or exchanged for cash or other property, and, immediately after consummation of such transaction, 9 Exhibit 4.21 the shareholders of the Issuer immediately prior to such transaction own the Common Stock, Other Securities or other voting stock of the Issuer in substantially the same proportions relative to each other as such shareholders owned immediately prior to such transaction), then, and in the case of each such transaction (each of which is referred to herein as "Business Combination"), proper provision shall be made so that, upon the basis and the terms and in the manner provided herein, the Holder, upon exercise of all or any part of this Warrant at any time after the consummation of such Business Combination, shall be entitled to receive upon such exercise, in lieu of the cash, property, Common Stock or Other Securities issuable upon such exercise prior to such consummation, any of the following, as shall be elected, in whole or in part, at least five (5) Business Days before such consummation (or, if the Holder fails to so elect, the Holder shall be deemed to have elected (B) below), by the Holder: (A) the Common Stock and Other Securities, cash and property to which the Holder would have been entitled upon such consummation if the Holder had held the Gross Number of shares of Common Stock (or Other Securities) immediately prior thereto, adjusted as nearly as possible to give effect to the net exercise provisions of Section 1.1(a); or (B) cash in an amount equal to the price of a European option determined pursuant to the Black-Scholes formula as computed using the Bloomberg Professional Service for the Gross Number of shares of Common Stock (or Other Securities) with respect to exercise of the portion of the Warrant for which this clause (B) is elected, using the following variables: (i) the "current price" shall be the closing price per share for the Common Stock (or Other Securities) as reported by the Bloomberg Professional Service for the primary exchange or quotation system on which such Common Stock (or Other Securities) traded on the Business Day immediately before the date such Business Combination was consummated; (ii) the "strike price" shall be the Warrant Price as of the Business Day immediately before the date such Business Combination was consummated; (iii) the "interest rate" shall be the yield to maturity for a U.S. Treasury security with a time to maturity equivalent to the time between the Business Day immediately before the date such Business Combination was consummated and the Termination Date; (iv) "volatility" shall be equal to seventy-five percent (75%) of the number reported by the Bloomberg Professional Service for the 260-Business-Day period as of the date that is five (5) Business Days before and excluding the date such Business Combination was announced (but in no event shall the "volatility" be greater than seventy-five percent (75%)); (v) the "expiration date" shall be the Termination Date; (vi) "trading date" shall be the Business Day immediately before the date such Business Combination was consummated; and (vii) "dividend yield" shall be zero percent (0%). The Holder shall not be obligated to pay any consideration (including, but not limited to, the Stock Purchase Price) in order to receive the consideration specified in this clause (B); provided, that if the Acquiring Person or its Parent, as the case may be, shall combine, subdivide or reclassify its common stock, or shall declare any dividend payable in shares of its common stock, or shall take any other action of a similar nature affecting such shares, the calculations above shall be adjusted to the extent appropriate to reflect such 10 Exhibit 4.21 event, including appropriate adjustments to account for any such event that occurs during any of the measurement periods set forth above. 3.2 Assumption of Obligations. Notwithstanding anything contained herein or in the Main Agreement to the contrary, the Issuer will not effect any Business Combination unless the requirements of Section 11 of the Main Agreement have been met and unless, prior to the consummation thereof, each Person (other than the Issuer) that may be required to deliver any stock, securities, cash or property upon exercise of this Warrant as provided herein shall assume, by written instrument delivered to, and reasonably satisfactory to, the Holder, (A) the obligations of the Issuer under this Warrant (and if the Issuer shall survive the consummation of such transaction, such assumption shall be in addition to, and shall not release the Issuer from, any continuing obligations of the Issuer under this Warrant) and (B) the obligation to deliver to the Holder such shares of stock, securities, cash or property as, in accordance with the foregoing provisions of this Section 3, the Holder may be entitled to receive, and such Person shall have similarly delivered to the Holder an opinion of counsel for such Person, which counsel shall be reasonably satisfactory to the Holder, stating that the rights of the Holder under this Warrant shall thereafter continue in full force and effect and the terms hereof, including, without limitation, all of the provisions of this Section 3 shall be applicable to the stock, securities, cash or property which such Person may be required to deliver upon any exercise of this Warrant or the exercise of any of the rights pursuant hereto. 4. Other Dilutive Events, Restatements. (a) In case any event shall occur as to which the provisions of Sections 2 and 3 are not strictly applicable (including, without limitation, the repurchase by the Issuer of Options or Convertible Securities) but the failure to make any adjustment would not fairly protect the purchase rights represented by this Warrant in accordance with the essential intent and principles of such Sections, then, in each such case, the Issuer shall notify the Holder of such event and, upon demand by the Holder, the Issuer shall appoint a firm of independent certified public accountants of recognized national standing (which shall not be the regular auditors of the Issuer), which shall give their opinion upon the adjustment, if any, on a basis consistent with the essential intent and principles established in Sections 2 and 3, necessary to preserve the value of the purchase rights represented by this Warrant. Such opinion shall include the basis for the calculations and conclusions contained therein in reasonable detail. Upon receipt of such opinion, the Issuer will promptly deliver a copy thereof via facsimile and overnight courier to the Holder or Holders of this Warrant and shall make the adjustments described therein. Upon written request by Holder, Issuer shall provide Holder with reasonable access to such information as may be necessary to evaluate the calculations and conclusions contained in such opinion. Within twenty (20) Business Days of receiving all such information Holder may dispute the conclusions of such opinion by providing a written notice of dispute to Issuer, which notice shall include the basis for the calculations and conclusions contained therein in reasonable detail. If Issuer and Holder are unable to agree to the appropriate calculation of such adjustment within ten (10) Business Days of such notice from Holder, then an independent nationally-recognized firm of certified public accountants selected by Holder and reasonably acceptable to Issuer shall be 11 Exhibit 4.21 appointed to resolve the dispute, and such accountants' decision shall be final and binding upon the Issuer and the Holder. The costs of such firm of certified public accountants shall be borne by Issuer. (b) In the event of a Restatement the Warrant Price shall equal the corresponding Restatement Purchase Price, if the Restatement Purchase Price is lower than the Warrant Price in effect on the date ninety (90) calendar days after and excluding such Restatement Date. "Restatement Purchase Price" means one hundred and fifty percent (150%) of the Average Market Price calculated on the date ninety (90) calendar days after and excluding the related Restatement Date. The Issuer shall deliver a Restatement Notice to the Holder no later than two (2) days after and excluding each Restatement Date. 5. No Impairment. The Issuer will not, by amendment of its certificate of incorporation or through any consolidation, merger, reorganization, transfer of assets, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such action as may be necessary or appropriate in order to protect the rights of the Holder of this Warrant against impairment. Without limiting the generality of the foregoing, the Issuer (a) will not permit the par value of any shares of stock receivable upon the exercise of this Warrant to exceed the amount payable therefor upon such exercise, (b) will take all such action as may be necessary or appropriate in order that the Issuer may validly and legally issue fully paid and nonassessable shares of stock on the exercise of the Warrants from time to time outstanding, and (c) will not take any action which results in any adjustment of the Warrant Price if the total number of shares of Common Stock (or Other Securities) issuable after the action upon the exercise of all of the Warrants would exceed the total number of shares of Common Stock (or Other Securities) then authorized by the Issuer's certificate of incorporation and available for the purpose of issue upon such exercise. 6. Accountants' Report as to Adjustments. In each case of any adjustment or readjustment in the shares of Common Stock (or Other Securities) issuable upon the exercise of this Warrant, the Issuer at its expense will promptly compute such adjustment or readjustment in accordance with the terms of this Warrant and cause independent certified public accountants of recognized national standing (which may be the regular auditors of the Issuer) selected by the Issuer to verify such computation and prepare a report setting forth such adjustment or readjustment and showing in reasonable detail the method of calculation thereof and the facts upon which such adjustment or readjustment is based, including but not limited to a statement of (a) the consideration received or to be received by the Issuer for any Additional Shares of Common Stock issued or sold or deemed to have been issued, (b) the number of shares of Common Stock outstanding or deemed to be outstanding, and (c) the Warrant Price in effect immediately prior to such issue or sale and as adjusted and readjusted (if required by Section 2, 3 or 4) on account thereof. The Issuer will forthwith mail a copy of each such report to each Holder of a Warrant and will, upon the written request at any time of any Holder of a Warrant, furnish to such Holder a copy of the most recent report setting forth the Warrant Price in effect as of the date such report is delivered and showing in reasonable detail how it was calculated.
