2.1. Manner of Exercise; Payment of the Purchase Price. (a) This Warrant may be exercised by the Holder hereof, in whole or in part, at any time or from time to time on and after June 30, 2004 and prior to the Expiration Date, by surrendering to the Company at its principal office this Warrant, with the form of Election to Purchase Shares attached hereto as

Exhibit A (or a reasonable facsimile thereof) duly executed by the Holder and accompanied by payment of the Purchase Price for the number of shares of Common Stock specified in such form (the “Aggregate Purchase Price”). Any partial exercise of this Warrant shall be for a whole number of Warrant Shares only.

(b) Payment of the Aggregate Purchase Price may be made as follows (or by any combination of the following): (i) in United States currency by cash or delivery of a certified check or bank draft payable to the order of the Company or by wire transfer to the Company, (ii) by cancellation of such number of the shares of Common Stock otherwise issuable to the Holder upon such exercise as shall be specified for cancellation in such Election to Purchase Shares, such that the excess of the aggregate Current Market Price of such specified number of shares on the date of exercise over the portion of the Aggregate Purchase Price attributable to such shares shall equal the Aggregate Purchase Price attributable to the shares of Common Stock to be issued upon such exercise, in which case such excess amount shall be deemed to have been paid to the Company and the number of shares issuable upon such exercise shall be reduced by such number specified for cancellation, or (iii) by surrender to the Company for cancellation certificates representing shares of Common Stock of the Company owned by the Holder (properly endorsed for transfer in blank) having a Current Market Price on the date of Warrant exercise equal to the Aggregate Purchase Price.

2.2. When Exercise Effective. Each exercise of this Warrant shall be deemed to have been effected immediately prior to the close of business on the Business Day on which this Warrant shall have been surrendered to, and the Purchase Price shall have been received by, the Company as provided in Section 2.1, and, to the extent permitted by law, at such time the Person or Persons in whose name or names any certificate or certificates for shares of Common Stock (or Other Securities) shall be issuable upon such exercise as provided in Section 2.3 shall be deemed to have become the holder or holders of record thereof for all purposes.

2.3. Delivery of Stock Certificates, etc.; Charges, Taxes and Expenses. (a) As soon as practicable after each exercise of this Warrant, in whole or in part, and in any event within five Business Days thereafter, the Company shall cause to be issued in the name of and delivered to the Holder hereof or, subject to Section 10, as the Holder may direct,

(i) a certificate or certificates for the number of shares of Common Stock (or Other Securities) to which the Holder shall be entitled upon such exercise, and

(ii) in case such exercise is for less than all of the shares of Common Stock purchasable under this Warrant, a new Warrant or Warrants of like tenor, for the balance of the shares of Common Stock purchasable hereunder.

(b) Issuance of certificates for shares of Common Stock upon the exercise of this Warrant shall be made without charge to the Holder hereof for any issue or transfer tax or other incidental expense, in respect of the issuance of such certificates, all of which such taxes and expenses shall be paid by the Company; provided, however, that the Company shall not be required to pay any tax that may be payable in respect of any issuance of any Warrant or any certificate for, or any other evidence of ownership of, Warrant Shares in a name other than that of the Initial Holder of this Warrant being exercised or exchanged.

2.4. Tax Basis. The Company and the Holder shall mutually agree as to the tax basis of this Warrant for purposes of the Internal Revenue Code of 1986, as amended, and the treatment of this Warrant under such Code by each of the Company and the Holder shall be consistent with such agreement.

3. ADJUSTMENT OF PURCHASE PRICE AND COMMON STOCK ISSUABLE UPON EXERCISE.

3.1. No Adjustment of Number of Warrant Shares. Except to the extent that the number of shares of Common Stock purchasable upon exercise of this Warrant shall be proportionately increased or decreased under Section 3.4 or 3.6 along with the then outstanding shares of the Company’s Common Stock upon the occurrence of a future stock split, stock dividend, reverse stock split, recapitalization or similar event, the number of shares of Common Stock purchasable upon exercise of this Warrant shall not be subject to adjustment.

3.2. Adjustment of Purchase Price.

3.2.1. Issuance of Additional Shares of Common Stock. In case the Company 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 pursuant to Section 3.3 or 3.4 but excluding Additional Shares of Common Stock purchasable upon exercise of Rights referred to in Section 3.10) without consideration or for a consideration per share less than the greater of the Purchase Price and the Current Market Price (the “New Securities Issuance Price”) in effect immediately prior to such issue or sale, then, and in each such case, subject to Section 3.8, the Purchase Price shall be reduced concurrently with such issue or sale, to a price equal to the product derived by multiplying (a) .9 by (b) the New Securities Issuance Price.

3.2.2. Extraordinary Dividends and Distributions. In the case the Company 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) a dividend payable in Additional Shares of Common Stock or (b) a regularly scheduled cash dividend (at a rate not in excess of 110% of the rate of the last regularly scheduled cash dividend theretofore paid) payable out of consolidated earnings or earned surplus, determined in accordance with generally accepted accounting principles, or (c) a dividend of Rights referred to in Section 3.10 hereof then, in each such case, subject to Section 3.8, the Purchase Price in effect immediately prior to the close of business on the record date fixed for the determination of holders of any class of securities entitled to receive such dividend or distribution shall be reduced, effective as of the close of business on such record date, to a price determined by multiplying such Purchase Price by a fraction

(x) the numerator of which shall be the Current Market Price in effect 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, less the Fair Value of such dividend or distribution applicable to one share of Common Stock, and

(y) the denominator of which shall be such Current Market Price.

provided that, in the event that the amount of such dividend as so determined is equal to or greater than 10% of such Current Market Price or in the event that such fraction is less than 9/10ths, in lieu of the foregoing adjustment, adequate provision shall be made so that the Holder shall receive, upon Warrant exercise, a pro rata share of such dividend based upon the maximum number of shares of Common Stock at the time issuable to the Holder (determined without regard to whether the Warrant is exercisable at such time.)

3.3. Treatment of Options and Convertible Securities. In case the Company 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 of the Company entitled to receive, any Options or Convertible Securities (whether or not the rights thereunder are immediately exercisable), then, and in each such case, the maximum number of Additional Shares of Common 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, 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 (i) the consideration per share (determined pursuant to Section 3.5) of such shares would be less than the Current Market 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 (ii) such Additional Shares of Common Stock are not purchasable pursuant to Rights referred to in Section 3.10, and provided, further, that in any such case in which Additional Shares of Common Stock are deemed to be issued:

(a) whether or not the Additional Shares of Common Stock underlying such Options or Convertible Securities are deemed to be issued, no further adjustment of the Purchase 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, except in the case of any such Options or Convertible Securities which contain provisions requiring an adjustment, subsequent to the date of the issue or sale thereof, of the number of Additional Shares of Common Stock issuable upon the exercise of such Options or the conversion or exchange of such Convertible Securities by reason of (x) a change of control of the Company, (y) the acquisition by any Person or group of Persons of any specified number or percentage of the voting securities of the Company or (z) any similar event or occurrence, each such case to be deemed hereunder to involve a separate issuance of Additional Shares of Common Stock, Options or Convertible Securities, as the case may be;

(b) if such Options or Convertible Securities by their terms provide, with the passage of time or otherwise, for any increase in the consideration payable to the Company, 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 Purchase 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 Company 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 Company and cancellation or retirement of any such Convertible Securities the rights of conversion or exchange under which) shall not have been exercised, the Purchase 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 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 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 Company for the issue, sale, grant or assumption of all such Options, whether or not exercised, plus the consideration actually received by the Company 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 Company 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 or sale, grant or assumption of such Options, and the consideration received by the Company for the Additional Shares of Common Stock deemed to have then been issued was the consideration actually received by the Company 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 Company (pursuant to Section 3.5) 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 decreasing the Purchase 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 Purchase

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.

3.4. Treatment of Stock Dividends, Stock Splits, etc. If the Company at any time after the date of issuance of this Warrant subdivides (by any stock split, stock dividend, recapitalization or otherwise) one or more classes of its outstanding shares of Common Stock into a greater number of shares, the Purchase Price in effect immediately prior to such subdivision will be proportionately reduced and the number of shares of Common Stock obtainable upon exercise of this Warrant will be proportionately increased. Any adjustment under this Section 3.4 shall become effective at the close of business on the date the subdivision or combination becomes effective.

3.5. Computation of Consideration. For the purposes of this Section 3,

(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 net cash proceeds to the Company, after deducting any expenses paid or incurred by the Company or any commissions or compensations paid or concessions or discounts 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, and

(iii) in case Additional Shares of Common Stock are issued or sold together with other stock or securities or other assets of the Company 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, such allocation to be determined in the same manner that the Fair Value of property not consisting of cash or securities is to be determined as provided in the definition of ‘Fair Value’ herein;

(b) Additional Shares of Common Stock deemed to have been issued pursuant to Section 3.3, 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 Company 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 Company 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),

(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; and

(c) Additional Shares of Common Stock deemed to have been issued pursuant to Section 3.4, relating to stock dividends, stock splits, etc., shall be deemed to have been issued for no consideration.

3.6. Adjustments for Combinations, etc. In case the outstanding shares of Common Stock shall be combined or consolidated, by reverse stock split, reclassification or otherwise, into a lesser number of shares of Common Stock, the Purchase Price in effect immediately prior to such combination or consolidation shall, concurrently with the effectiveness of such combination or consolidation, be proportionately increased and the number of shares of Common Stock purchasable upon exercise of this Warrant proportionately decreased.

3.7. 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 Company (or any issuer of Other Securities or any other Person referred to in Section 4) or to subscription, purchase or other acquisition pursuant to any Options issued or granted by the Company (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 3, the purchase rights, if any, with respect to such Other Securities, granted by this Warrant, then, and in each such case, the computations, adjustments and readjustments provided for in this Section 3 with respect to the Purchase 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 Warrants, so as to protect the holders of the Warrants against the effect of such dilution.

3.8. De Minimis Adjustments. If the amount of any adjustment of the Purchase Price required pursuant to this Section 3 would be less than one tenth (1/10) of one percent (1%) of the Purchase 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 a change in the Purchase Price of at least one tenth (1/10) of one percent (1%) of such Purchase Price. All calculations under this Warrant shall be made to the nearest one-hundredth of a share.

3.9. Abandoned Dividend or Distribution. If the Company shall take a record of the holders of its Common Stock for the purpose of entitling them to receive a dividend or other distribution (which results in an adjustment to the Purchase Price under the terms of this Warrant) and shall, thereafter, and before such dividend or distribution is paid or delivered to shareholders entitled thereto, legally abandon its plan to pay or deliver such dividend or distribution, then any adjustment made to the Purchase Price by reason of the taking of such record shall be reversed, and any subsequent adjustments, based thereon, shall be recomputed.

3.10. Shareholder Rights Plan. Notwithstanding the foregoing, in the event that the Company shall distribute “poison pill” rights pursuant to a “poison pill” shareholder rights plan (the “Rights”), the Company shall, in lieu of making any adjustment pursuant to Section 3.2.1 or Section 3.2.2 hereof, make proper provision so that each Holder who exercises a Warrant after the record date for such distribution and prior to the expiration or redemption of the Rights shall be entitled to receive upon such exercise, in addition to the shares of Common Stock issuable upon such exercise, a number of Rights to be determined as follows: (i) if such exercise occurs on or prior to the date for the distribution to the holders of Rights of separate certificates evidencing such Rights (the “Distribution Date”), the same number of Rights to which a holder of a number of shares of Common Stock equal to the number of shares of Common Stock issuable upon such exercise at the time of such exercise would be entitled in accordance with the terms and provisions of and applicable to the Rights; and (ii) if such exercise occurs after the Distribution Date, the same number of Rights to which a holder of the number of shares into which the Warrant so exercised was exercisable immediately prior to the Distribution Date would have been entitled on the Distribution Date in accordance with the terms and provisions of and applicable to the Rights.

4. CONSOLIDATION, MERGER, ETC.

4.1. Adjustments for Consolidation, Merger, Sale of Assets, Reorganization, etc. In case the Company after the date hereof (a) shall consolidate with or merge into any other Person and shall not be the continuing or surviving corporation of such consolidation or merger, or (b) shall permit any other Person to consolidate with or merge into the Company and the Company shall be the continuing or surviving Person but, in connection with such consolidation or merger, the Common Stock or Other Securities shall be changed into or exchanged for stock or other securities of any other Person or cash or any other property, or (c) shall transfer all or substantially all of its properties or assets to any other Person, or (d) shall effect a capital reorganization or reclassification of the Common Stock or Other Securities (other than a capital reorganization or reclassification resulting in the issue of Additional Shares of Common Stock for which adjustment in the Purchase Price is provided in Section 3.2.1 or 3.2.2), then, and in the case of each such transaction, proper provision shall be made so that, upon the basis and the terms and in the manner provided in this Warrant, the Holder of this Warrant, upon the exercise hereof at any time after the consummation of such transaction, shall be entitled to receive (at the aggregate Purchase Price in effect at the time of such consummation for all Common Stock or Other Securities issuable upon such exercise immediately prior to such consummation), in lieu of the Common Stock or Other Securities issuable upon such exercise prior to such consummation, the highest amount of securities, cash or other property to which such Holder would actually have been entitled as a shareholder upon such consummation if such Holder had exercised this Warrant immediately prior thereto, subject to adjustments (subsequent to such consummation) as nearly equivalent as possible to the adjustments provided for in Sections 3 through 5, provided that if a purchase, tender or exchange offer shall have been made to and accepted by the holders of more than 50% of the outstanding shares of Common Stock (a “Change of Control”), and if the Holder so designates in a notice given to the Company on or before the date immediately preceding the date of the consummation of such transaction, the Holder of this Warrant shall be entitled to receive the highest amount of securities, cash or other property to which it would actually have been entitled as a shareholder if the Holder of this Warrant had exercised this

Warrant prior to the expiration of such purchase, tender or exchange offer and accepted such offer, subject to adjustments (from and after the consummation of such purchase, tender or exchange offer) as nearly equivalent as possible to the adjustments provided for in Section 3 through 5.

4.2. Assumption of Obligations. Notwithstanding anything contained in this Warrant to the contrary, the Company shall not effect any of the transactions described in clauses (a) through (d) of Section 4.1 unless, prior to the consummation thereof, each Person (other than the Company) which may be required to deliver any stock, securities, cash or property upon the exercise of this Warrant as provided herein shall assume, by written instrument delivered to, and reasonably satisfactory to, the Holder of this Warrant, (a) the obligations of the Company under this Warrant (and if the Company shall survive the consummation of such transaction, such assumption shall be in addition to, and shall not release the Company from, any continuing obligations of the Company under this Warrant), (b) the obligations of the Company under the Registration Rights Agreement and (c) 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 4, the Holder may be entitled to receive.

5. OTHER DILUTIVE EVENTS. In case any event shall occur as to which the provisions of Section 3 or Section 4 hereof are not strictly applicable or if strictly applicable would not fairly protect the purchase rights of the Holder in accordance with the essential intent and principles of such Sections, then in each such case, the Board of Directors of the Company shall make an adjustment in the application of such provisions, in accordance with such essential intent and principles, so as to preserve, without dilution, the purchase rights represented by this Warrant.

6. NO DILUTION OR IMPAIRMENT. The Company shall 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 dilution or other impairment. Without limiting the generality of the foregoing, the Company (a) shall 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) shall take all such action as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable shares of stock, free from all liens, security interests, encumbrances (in each of the foregoing cases, other than those imposed by the Holder), taxes, preemptive rights and charges on the exercise of the Warrants from time to time outstanding, and (c) shall not take any action which results in any adjustment of the Purchase 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 Company’s Articles of Organization and available for the purpose of issue upon such exercise.

7. ACCOUNTANTS’ REPORT. In each case of any adjustment or readjustment in the number of shares of Common Stock (or Other Securities) issuable upon the

exercise of this Warrant or in the Purchase Price, the Company at its sole expense shall 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 Company) selected by the Company to verify such computation (other than any computation of the Fair Value of property) 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 a statement of (a) the consideration received or to be received by the Company 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 Purchase Price in effect immediately prior to such issue or sale and as adjusted and readjusted (if required by Section 3) on account thereof. The Company shall forthwith mail a copy of each such report to each holder of a Warrant. The Company shall also keep copies of all such reports at its principal office and shall cause the same to be available for inspection at such office during normal business hours by any holder of a Warrant or any prospective purchaser of a Warrant designated by the holder thereof.

8. NOTICES OF CORPORATE ACTION. In the event of:

(a) any taking by the Company of a record of the holders of any class of securities for the purpose of determining the holders thereof who are entitled to receive any dividend or other distribution, or any right to subscribe for, purchase or otherwise acquire any shares of stock of any class or any other securities or property, or to receive any other right, or

(b) any capital reorganization of the Company, any reclassification or recapitalization of the capital stock of the Company, any consolidation or merger involving the Company and any other Person, any transaction or series of transactions in which more than 50% of the voting securities of the Company are transferred to another Person, or any transfer, sale or other disposition of all or substantially all the assets of the Company to any other Person, or

the Company shall mail to each holder of a Warrant a notice specifying (i) the date or expected date on which any such record is to be taken for the purpose of such dividend, distribution or right, and the amount and character of such dividend, distribution or right, and (ii) the date or expected date on which any such reorganization, reclassification, recapitalization, consolidation, merger, transfer, sale, disposition, dissolution, liquidation or winding-up is to take place and the time, if any such time is to be fixed, as of which the holders of record of Common Stock (or Other Securities) shall be entitled to exchange their shares of Common Stock (or Other Securities) for the securities or other property deliverable upon such reorganization, reclassification, recapitalization, consolidation, merger, transfer, dissolution, liquidation or winding-up. Such notice shall be mailed at least 20 days prior to the date therein specified.

9. REGISTRATION OF COMMON STOCK. If any shares of Common Stock required to be reserved for purposes of exercise of this Warrant require registration with or approval of any governmental authority under any federal or state law (other than the Securities

Act) before such shares may be issued upon exercise, the Company shall, at its expense and as expeditiously as possible, use its best efforts to cause such shares to be duly registered or approved, as the case may be. At any such time as Common Stock is listed on any national securities exchange, the Company shall, at its expense, obtain promptly and maintain the approval for listing on each such exchange, upon official notice of issuance, the shares of Common Stock issuable upon exercise of the then outstanding Warrants and maintain the listing of such shares after their issuance; and the Company shall also list on such national securities exchange, shall register under the Exchange Act and shall maintain such listing of, any Other Securities that at any time are issuable upon exercise of the Warrants, if and at the time that any securities of the same class shall be listed on such national securities exchange by the Company.

10. RESTRICTIONS ON TRANSFER.

10.1. Restrictive Legends. Except as otherwise permitted by this Section 10, each Warrant (including each Warrant issued upon the transfer of any Warrant) shall be stamped or otherwise imprinted with a legend in substantially the following form:

“THIS WARRANT AND ANY SECURITIES ACQUIRED UPON THE EXERCISE OF THIS WARRANT HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR THE SECURITIES LAW OF ANY STATE, AND MAY NOT BE SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT AND APPLICABLE STATE SECURITIES LAWS OR PURSUANT TO AN APPLICABLE EXEMPTION TO THE REGISTRATION REQUIREMENTS OF SUCH ACT AND SUCH LAWS. THIS WARRANT AND SUCH SECURITIES MAY NOT BE SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF EXCEPT IN COMPLIANCE WITH THE CONDITIONS SPECIFIED IN THIS WARRANT.

Except as otherwise permitted by this Section 10, each certificate for Common Stock (or Other Securities) issued upon the exercise of any Warrant, and each certificate issued upon the transfer of any such Common Stock (or Other Securities), shall be stamped or otherwise imprinted with a legend in substantially the following form:

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR THE SECURITIES LAW OF ANY STATE, AND MAY NOT BE SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT AND APPLICABLE STATE SECURITIES LAWS OR PURSUANT TO AN APPLICABLE EXEMPTION TO THE REGISTRATION REQUIREMENTS OF SUCH ACT AND SUCH LAWS. SUCH SECURITIES MAY NOT BE SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF EXCEPT IN COMPLIANCE WITH THE CONDITIONS SPECIFIED IN THE COMMON STOCK PURCHASE WARRANT ISSUED BY CLEAN HARBORS, INC., A COMPLETE AND CORRECT COPY OF WHICH IS AVAILABLE FOR INSPECTION AT THE COMPANY’S PRINCIPAL OFFICE

AND WILL BE FURNISHED TO THE HOLDER OF SUCH SECURITIES UPON WRITTEN REQUEST AND WITHOUT CHARGE.”

10.2. Transfer to Comply With the Securities Act. Restricted Securities may not be sold, assigned, pledged, hypothecated, encumbered or in any manner transferred or disposed of (a “Transfer”), in whole or in part, except in compliance with the provisions of the Securities Act and state securities or Blue Sky laws and the terms and conditions hereof.

10.3. Termination of Restrictions. The restrictions imposed by this Section 10 on the transferability of Restricted Securities shall cease and terminate as to any particular Restricted Securities (a) when a registration statement with respect to the sale of such securities shall have been declared effective under the Securities Act and such securities shall have been disposed of in accordance with such registration statement, (b) when such securities are sold pursuant to Rule 144 (or any similar provision then in force) under the Securities Act, or (c) when, in the reasonable opinion of both counsel for the Holder and counsel for the Company, such restrictions are no longer required or necessary in order to protect the Company against a violation of the Securities Act upon any sale or other disposition of such securities without registration thereunder. Whenever such restrictions shall cease and terminate as to any Restricted Securities, the Holder shall be entitled to receive from the Company, without expense, new securities of like tenor not bearing the applicable legends required by Section 10.1.

10.4. Exempt Transfers. The restrictions on the transfer of this Warrant or the Warrant Shares set forth in this Section 10 shall not apply to any transfer made in compliance with applicable state and federal securities laws.

11. RESERVED.

12. RESERVATION OF STOCK, ETC. The Company shall at all times reserve and keep available, solely for issuance and delivery upon exercise of the Warrants, the number of shares of Common Stock (or Other Securities) from time to time issuable upon exercise of the Warrants (the “Required Reserve Amount”). The initial number of shares of Common Stock reserved for issuance upon exercise of all Warrants and each increase (or decrease) in the number of shares so reserved shall be allocated pro rata among the holders of Warrants based on the number of shares of Common Stock issuable upon exercise of the Warrants held by each holder on June 30, 2004 or the effective date of such increase (or decease) in the number of reserved shares, as the case may be (the “Authorized Share Allocation”). In the event that a holder shall sell or otherwise transfer any of such holder’s Warrants, each transferee shall be allocated a pro rata portion of such holder’s Authorized Share Allocation. Any shares of Common Stock reserved and allocated to any Person which ceases to hold any Warrants shall be allocated to the remaining holders of Warrants, pro rata based on the number of shares of Common Stock issuable upon exercise of the Warrants then held by such holders. All shares of Common Stock (or Other Securities) issuable upon exercise of any Warrant shall be duly authorized and, when issued upon such exercise, shall be validly issued and, in the case of shares, fully paid and nonassessable, with no liability on the part of the holders thereof, and, in the case of all securities, shall be free from all liens, security interests, encumbrances (in each of the foregoing cases, other than those imposed by the Holder), taxes, preemptive rights and charges. The transfer agent for the Common Stock, and every subsequent transfer agent for any

shares of the Company’s capital stock issuable upon the exercise of any of the purchase rights represented by this Warrant, are hereby irrevocably authorized and directed at all times until the Expiration Date to reserve such number of authorized and unissued shares as shall be requisite for such purpose. The Company shall keep copies of this Warrant on file with the transfer agent for the Common Stock 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 this Warrant. The Company shall supply such transfer agent with duly executed stock certificates for such purpose. All Warrant Certificates surrendered upon the exercise of the rights thereby evidenced shall be canceled, and such canceled Warrants shall constitute sufficient evidence of the number of shares of stock which have been issued upon the exercise of such Warrants.

13. REGISTRATION AND TRANSFER OF WARRANTS, ETC.

13.1. Warrant Register; Ownership of Warrants. Each Warrant issued by the Company shall be numbered and shall be registered in a warrant register (the “Warrant Register”) as it is issued and transferred, which Warrant Register shall be maintained by the Company at its principal office or, at the Company’s election and expense, by a Warrant Agent or the transfer agent. The Company shall be entitled to treat the registered Holder of any Warrant on the Warrant Register as the owner in fact thereof for all purposes and shall not be bound to recognize any equitable or other claim to or interest in such Warrant on the part of any other Person, and shall not be affected by any notice to the contrary, except that, if and when any Warrant is properly assigned in blank, the Company may (but shall not be obligated to) treat the bearer thereof as the owner of such Warrant for all purposes. Subject to Section 10, a Warrant, if properly assigned, may be exercised by a new holder without a new Warrant first having been issued.

13.2. Transfer of Warrants. Subject to compliance with Section 10, if applicable, this Warrant and all rights hereunder are transferable in whole or in part, without charge to the Holder hereof, upon surrender of this Warrant with a properly executed Form of Assignment attached hereto as Exhibit B at the principal office of the Company. Upon any partial transfer, the Company shall at its expense issue and deliver to the Holder a new Warrant of like tenor, in the name of the Holder, which shall be exercisable for such number of shares of Common Stock with respect to which rights under this Warrant were not so transferred.

13.3. Replacement of Warrants. On receipt by the Company of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant and, in the case of any such mutilation, on surrender of such Warrant to the Company at its principal office and cancellation thereof, the Company at its expense shall execute and deliver, in lieu thereof, a new Warrant of like tenor.

13.4. Adjustments To Purchase Price and Number of Shares. Notwithstanding any adjustment in the Purchase Price or in the number or kind of shares of Common Stock purchasable upon exercise of this Warrant, any Warrant theretofore or thereafter issued may continue to express the same number and kind of shares of Common Stock as are stated in this Warrant, as initially issued. The provisions of this Section 13.4 shall, however, in no manner affect the number or kind of shares of Common Stock issuable upon exercise of this Warrant, which shall be determined in accordance with the other provisions of this Warrant.

13.5. Fractional Shares. Notwithstanding any adjustment pursuant to Section 3 in the number of shares of Common Stock covered by this Warrant or any other provision of this Warrant, the Company shall not be required to issue fractions of shares upon exercise of this Warrant or to distribute certificates which evidence fractional shares. In lieu of fractional shares, the Company shall make payment to the Holder, at the time of exercise of this Warrant as herein provided, in an amount in cash equal to such fraction multiplied by the Current Market Price of a share of Common Stock on the date of Warrant exercise.

14. REMEDIES; SPECIFIC PERFORMANCE. The Company stipulates that there would be no adequate remedy at law to the Holder of this Warrant in the event of any default or threatened default by the Company in the performance of or compliance with any of the terms of this Warrant and accordingly, the Company agrees that, in addition to any other remedy to which the Holder may be entitled at law or in equity, the Holder shall be entitled to seek to compel specific performance of the obligations of the Company under this Warrant, without the posting of any bond, in accordance with the terms and conditions of this Warrant in any court of the United States or any State thereof having jurisdiction, and if any action should be brought in equity to enforce any of the provisions of this Warrant, the Company shall not raise the defense that there is an adequate remedy at law. Except as otherwise provided by law, a delay or omission by the Holder hereto in exercising any right or remedy accruing upon any such breach shall not impair the right or remedy or constitute a waiver of or acquiescence in any such breach. No remedy shall be exclusive of any other remedy. All available remedies shall be cumulative.

15. NO RIGHTS OR LIABILITIES AS SHAREHOLDER. Nothing contained in this Warrant shall be construed as conferring upon the Holder hereof any rights as a shareholder of the Company or as imposing any obligation on the Holder to purchase any securities or as imposing any liabilities on the Holder as a shareholder of the Company, whether such obligation or liabilities are asserted by the Company or by creditors of the Company.

16. NOTICES. All notices and other communications (and deliveries) provided for or permitted hereunder shall be made in writing by hand delivery, telecopier, any nationally-recognized courier guaranteeing overnight delivery or first class registered or certified mail, return receipt requested, postage prepaid, addressed as follows:

17. AMENDMENTS. This Warrant and any term hereof may not be amended, modified, supplemented or terminated, and waivers or consents to departures from the provisions hereof may not be given, except by written instrument duly executed by the party against which enforcement of such amendment, modification, supplement, termination or consent to departure is sought.

18. DESCRIPTIVE HEADINGS, ETC. The headings in this Warrant are for convenience of reference only and shall not limit or otherwise affect the meaning of terms contained herein. Unless the context of this Warrant otherwise requires: (1) words of any gender shall be deemed to include each other gender; (2) words using the singular or plural number shall also include the plural or singular number, respectively; (3) the words “hereof”, “herein” and “hereunder” and words of similar import when used in this Warrant shall refer to this Warrant as a whole and not to any particular provision of this Warrant, and Section and paragraph references are to the Sections and paragraphs of this Warrant unless otherwise specified; (4) the word “including” and words of similar import when used in this Warrant shall mean “including, without limitation,” unless otherwise specified; (5) “or” is not exclusive; and (6) provisions apply to successive events and transactions.

19. GOVERNING LAW. This Agreement shall be governed by and construed in accordance with the law of the State of New York.

20. REGISTRATION RIGHTS AGREEMENT. The shares of Common Stock (and Other Securities) issuable upon exercise of this Warrant (or upon conversion of any shares of Common Stock issued upon such exercise) shall constitute Registrable Securities (as such term is defined in the Registration Rights Agreement). Each holder of this Warrant shall be entitled to all of the benefits afforded to a Holder of any such Registrable Securities under the Registration Rights Agreement and such Holder, by its acceptance of this Warrant, agrees to be

bound by and to comply with the terms and conditions of the Registration Rights Agreement applicable to such holder as a Holder of such Registrable Securities.

21. NOTICE. Notwithstanding any other provision herein to the contrary, the Company agrees to provide the Holder with no less than thirty (30) days prior written notice of the Expiration Date in order for the Holder, in its sole discretion, to exercise its right to acquire any or all of the Warrant Shares hereunder. To the extent such notice is not given in a timely manner, the otherwise applicable Expiration Date shall not be deemed to have occurred until 30 days after delivery of such notice.

22. EXPIRATION. The right to exercise this Warrant shall expire at 5:00 p.m., New York City time, on September 10, 2009.

23. COSTS AND ATTORNEYS’ FEES. In the event that any action, suit or other proceeding is instituted concerning or arising out of this Warrant, the Company agrees and the Holder, by taking and holding this Warrant agrees, that the prevailing party shall recover from the non-prevailing party all of such prevailing party’s costs and reasonable attorneys’ fees incurred in each and every such action, suit or other proceeding, including any and all appeals or petitions therefrom.

24. MOST FAVORED HOLDER. The Company agrees that if at any time or from time to time prior to the Expiration Date it enters into any agreement with, or issues Options or Convertible Securities to, any Person other than a Holder of this Warrant, which provides such Person with more favorable terms of the type set forth in Sections 3, 4, 5 and 6 of this Warrant (collectively, “More Favorable Terms”), then the Company shall issue to the Holder a new Warrant in exchange for this Warrant, effective from the date such agreement is consummated or Option or Convertible Security is issued until the Expiration Date. The terms of such new Warrant shall contain such More Favorable Terms or other terms as may then be mutually agreed by the Company and the Holder as providing economic benefits not less favorable to the Holder than such More Favorable Terms. In no event, however, shall such new Warrant be exercisable into a greater number of Warrant Shares than this Warrant and such limitation shall be taken into account in determining whether the terms of the new Warrant provide economic benefits not less favorable to the Holder than such More Favorable Terms.

25. REQUIRED ACTION UPON AUTHORIZED SHARE FAILURE. If at any time while any of the Warrants remain outstanding the Company does not have a sufficient number of authorized and unreserved shares of Common Stock to satisfy its obligation to reserve for issuance upon exercise of all of the Warrants at least a number of shares of Common Stock equal to the Required Reserve Amount (an “Authorized Share Failure”), then the Company shall immediately take all action necessary to increase the Company’s authorized shares of Common Stock to an amount sufficient to allow the Company to reserve the Required Reserve Amount for the Warrants then outstanding. Without limiting the generality of the foregoing sentence, as soon as practicable after the date of the occurrence of an Authorized Share Failure, but in no event later than 75 days after the occurrence of such Authorized Share Failure, the Company shall hold a meeting of its stockholders for the approval of an increase in the number of authorized shares of Common Stock. In connection with such meeting, the Company shall

provide each stockholder with a proxy statement and shall use its reasonable best efforts to solicit its stockholders’ approval of such increase in authorized shares of Common Stock. In the event that notwithstanding the foregoing, the Company is unable to issue any Warrant Shares for which an Election to Purchase Shares has been received as a result of an Authorized Share Failure, the Company shall pay cash in exchange for cancellation of such Warrant Shares, at a price per Warrant Share equal to the difference between the Current Market Price and the Purchase Price as of the date of the attempted exercise.
