Upon initial issuance, each Warrant shall be dated as of the date of signature thereof by the Company. (b) Register. Each Warrant issued, exchanged or transferred hereunder shall be registered in a warrant register (the "WARRANT REGISTER"). The Warrant Register shall set forth the number of each Warrant, the name and address of the Holder thereof and the original number of Warrant Shares purchasable upon the exercise thereof.

(a) Exchange. The Holder may exchange any Warrant or Warrants issued hereunder for another Warrant or Warrants of like kind and tenor representing in the aggregate the right to purchase the same number of Warrant Shares that could be purchased pursuant to the Warrant or Warrants being so exchanged. In order to effect an exchange permitted by this Section 3.2, the Holder shall deliver to the Company such Warrant or Warrants accompanied by a written request signed by the Holder thereof specifying the number and denominations of Warrants to be issued in such exchange and the names in which such Warrants are to be issued. As promptly as practicable but in any event within ten (10) Business Days of receipt of such a request, the Company shall, without charge, issue, register and deliver to the Holder thereof each Warrant to be issued in such exchange. (b) Replacement. Upon receipt of evidence reasonably satisfactory to the Company (an affidavit of the Holder being satisfactory) of the ownership and the loss, theft, destruction or mutilation of any Warrant, and in the case of any such loss, theft or destruction, upon receipt of an indemnity reasonably satisfactory to the Company (if the Holder is a financial institution or other institutional investor, its own agreement being satisfactory) or, in the case of any such mutilation, upon surrender of such Warrant, the Company shall, without charge, issue register and deliver in lieu of such Warrant a new Warrant of like kind representing the same -8- rights represented by and dated the date of such lost, stolen, destroyed or mutilated Warrant. Any such new Warrant shall constitute an original contractual obligation of the Company, whether or not the allegedly lost, stolen, mutilated or destroyed Warrant shall be at any time enforceable by any Person. (c) Expenses. The Company shall pay all expenses and taxes (other than any applicable income or similar taxes payable by a Holder of a Warrant) attributable to an exchange of a Warrant pursuant to this Section 3.2; provided, however, that the Company shall not be required to pay any tax that may be payable in respect of any transfer involved in the issuance of any Warrant in a name other than that of the Holder of the Warrant being exchanged. 3.3 TRANSFER OF WARRANT. Subject to the provisions of the Securities Purchase Agreement (including, without limitation, Article VI thereof), each Warrant may be transferred, in whole or in part, to an "accredited investor", as such term is defined in Rule 501(a) promulgated pursuant to the Securities Act, by the Holder thereof by delivering to the Company such Warrant accompanied by a properly completed, duly executed, Assignment Form. As promptly as practicable but in any event within ten (10) Business Days of receipt of such Assignment Form, the Company shall, without charge, issue, register and deliver to the Holder thereof a new Warrant or Warrants of like kind and tenor representing in the aggregate the right to purchase the same number of Warrant Shares that could be purchased pursuant to the Warrant being transferred. In all cases of transfer by an attorney, the original power of attorney, duly approved, or a copy thereof, duly certified, shall be deposited and remain with the Company. In case of transfer by executors, administrators, guardians or other legal representatives, duly authenticated evidence of their authority shall be produced and may be required to be deposited and remain with the Company in its discretion. The Company shall not be liable for complying with a request by a fiduciary or nominee of a fiduciary to register a transfer of any Warrant which is registered in the name of such fiduciary or nominee, unless made with the actual knowledge that such fiduciary or nominee is committing a breach of trust in requesting such registration of transfer, or with knowledge of such facts that the Company's participation therein amounts to bad faith. 3.4 TRANSFER; LEGENDS. The provisions of Article VI of the Purchase Agreement shall apply to the Warrants and the Warrant Shares. -9- ARTICLE IV EXERCISE OF WARRANT; EXCHANGE FOR WARRANT SHARES 4.1 EXERCISE OF WARRANTS. On any Business Day on or prior to the Expiration Time, a Holder may exercise a Warrant, in whole or in part, by delivering to the Company such Warrant accompanied by a properly completed Exercise Form and a certified or bank check or wire transfer in an aggregate amount equal to the product obtained by multiplying (a) the Exercise Price times (b) the number of Warrant Shares being purchased. Any partial exercise of a Warrant shall be for a whole number of Warrant Shares only. 4.2 EXCHANGE FOR WARRANT SHARES. On any Business Day on or prior to the Expiration Time, a Holder may exchange a Warrant, in whole or in part, for Warrant Shares by delivering to the Company such Warrant accompanied by a properly completed Exchange Form. The number of shares of Common Stock to be received by a Holder upon such exchange shall be equal to (a) the number of Warrant Shares allocable to the portion of the Warrant being exchanged (the "ALLOCABLE NUMBER"), as specified by such Holder in the Exchange Form less (b) the number of shares equal to the quotient obtained by dividing (i) the product obtained by multiplying (A) the Exercise Price times (B) the Allocable Number by (ii) the Market Price as of the Delivery Date (as defined below). The Allocable Number need not be a whole number, but in the case of any partial exchange of a Warrant under this Section 4.2, the Allocable Number shall be determined so that the number of Warrant Shares to be issued in such exchange shall be a whole number only. 4.3 ISSUANCE OF COMMON STOCK. (a) Issuance of Common Stock. As promptly as practicable but in any event within ten (10) Business Days following the delivery date (the "DELIVERY DATE") of (i) an Exercise Form or Exchange Form in accordance with Section 4.1 or 4.2, (ii) the related Warrant and (iii) any required payment of the Exercise Price, the Company shall, without charge, issue, register and deliver one or more stock certificates representing the aggregate number of shares of Common Stock to which the Holder of such Warrant is entitled and, upon compliance with the applicable provisions of this Warrant Agreement and the Securities Purchase Agreement, transfer to such Holder appropriate evidence of ownership of other securities or property (including any cash) to which such Holder is entitled, in such denominations, and registered or otherwise placed in, or payable to the order of, such name or names, as may be directed in writing by such Holder. The Company shall deliver such stock certificates, evidence of ownership and any other securities or property (including any cash) to the Person or Persons entitled to receive the same, together with an amount in cash in lieu of any fraction of a share (or fractional interest in any other security), as hereinafter provided. -10- (b) Partial Exercise or Exchange. If a Holder shall exercise or exchange a Warrant for less than all of the Warrant Shares that could be purchased or received thereunder, the Company shall issue, register and deliver to the Holder, as promptly as practicable but in any event within ten (10) Business Days of the Delivery Date, a new Warrant evidencing the right to purchase the remaining Warrant Shares. In the case of an exchange pursuant to Section 4.2, the number of remaining Warrant Shares shall be the original number of Warrant Shares subject to the Warrant so exchanged reduced by the Allocable Number. Each Warrant surrendered pursuant to Section 4.1 or 4.2 shall be canceled. (c) Fractional Shares. The Company shall not be required to issue fractional shares of Common Stock or fractional units of any other security upon the exercise or exchange of a Warrant. If any fraction of a share of Common Stock or fractional unit of any other security would be issuable on the exercise or exchange of any Warrant, the Company may, in lieu of issuing such fractional share or unit, pay to such Holder for any such fraction an amount in cash equal to the product obtained by multiplying (i) such fraction times (ii) the Market Price for the Common Stock or for a unit of such other security, as the case may be, as of the Delivery Date. (d) Expenses. The Company shall pay all expenses and taxes (other than any applicable income or similar taxes payable by a Holder of a Warrant) attributable to the initial issuance of Warrant Shares upon the exercise or exchange of a Warrant; provided, however, that the Company shall not be required to pay any tax that may be payable in respect of any transfer involved in the 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 Holder of the Warrant being exercised or exchanged. (e) Record Ownership. To the extent permitted by Applicable Law, the Person in whose name any certificate for shares of Common Stock or other evidence of ownership of any other security is issued upon exercise or exchange of a Warrant shall for all purposes be deemed to have become the holder of record of such shares or other security on the Delivery Date, irrespective of the date of delivery of such certificate or other evidence of ownership (subject, in the case of any exercise to which Section 4.3(h) applies, to the consummation of a transaction upon which such exercise is conditioned), notwithstanding that the transfer books of the Company shall then be closed or that such certificates or other evidence of ownership shall not then actually have been delivered to such Person. (f) Approvals. If any securities constituting Warrant Shares or any portion thereof to be issued upon exercise or exchange of a Warrant require registration or approval under any Applicable Law or require listing on any national securities exchange or quotation systems before such securities may be so issued, the Company will as expeditiously as possible cause such securities to be registered, approved or listed, as applicable. The Company may suspend the exercise of any Warrant so affected for the period during which such registration, approval or listing is required but not in effect. -11- (g) Quotation. On or before the Closing Date, the Company shall have filed with The Nasdaq National Market a notification form for the listing of additional shares with respect to the Warrant Shares, and the Company shall file any and all agreements, forms and other documents, and take all other action necessary for the listing of such shares on or before the tenth day following the Closing Date. The Company shall maintain the designation or quotation, or listing, of its Common Stock on the Nasdaq National Market (or on the New York Stock Exchange or the American Stock Exchange) or the Nasdaq Small-Cap Market (if the Common Stock becomes ineligible for quotation on the Nasdaq National Market) until the date on which none of the Warrants or Warrant Shares remain outstanding, unless the Company fails to maintain the criteria or other standards for such designation, listing or quotation; provided, however, that the Company shall use its reasonable best efforts to maintain any such designation, listing or quotation. (h) Conditional Exercise or Exchange. Any Exercise Form or Exchange Form delivered under Section 4.1 or 4.2 may condition the exercise or exchange of any Warrant on the consummation of a transaction being undertaken by the Company or the Holder of such Warrant, and such exercise or exchange shall not be deemed to have occurred except concurrently with the consummation of such transaction, except that, for purposes of determining whether such exercise or exchange is timely it shall be deemed to have occurred on the Delivery Date. If any exercise of a Warrant is so conditioned, then, subject to delivery of the items required by Section 4.3(a) and compliance with the other terms hereof, the Company shall deliver the certificates and other evidence of ownership of other securities or other property in such manner as such Holder shall direct as required in connection with the consummation such transaction upon which the exercise is conditioned. At any time that such Holder shall give notice to the Company that such transaction has been abandoned or such Holder has withdrawn from participation in such transaction, the Company shall return the items delivered pursuant to Section 4.3(a), and such Holder's election to exercise such Warrant shall be deemed rescinded. ARTICLE V ADJUSTMENT OF EXERCISE PRICE AND SHARES. 5.1 GENERAL. The Exercise Price and the number and kind of Warrant Shares issuable upon exercise of each Warrant shall be subject to adjustment from time to time in accordance with this Article V. 5.2 STOCK DIVIDENDS, SUBDIVISIONS AND COMBINATIONS. If, at any time after the Closing Date, the Company shall: (i) pay a dividend in shares of Common Stock or make a distribution in shares of Common Stock; or -12- (ii) subdivide, split or reclassify its outstanding shares of Common Stock into a larger number of shares of Common Stock; or (iii) combine its outstanding shares of Common Stock into a smaller number of shares of Common Stock; then (A) the number of Warrant Shares issuable upon exercise of each Warrant shall be adjusted so as to equal the number of Warrant Shares that the Holder of such Warrant would have held immediately after the occurrence of such event if the Holder had exercised such Warrant immediately prior to the occurrence of such event and (B) the Exercise Price shall be adjusted to be equal to (x) the Exercise Price immediately prior to the occurrence of such event multiplied by (y) a fraction (1) the numerator of which is the number of Warrant Shares issuable upon exercise of this Warrant immediately prior to the adjustment in clause (A) and (2) the denominator of which is the number of Warrant Shares issuable upon exercise of this Warrant immediately after the adjustment in clause (A). An adjustment made pursuant to this Section 5.2 shall become effective immediately after the occurrence of such event retroactive to the record date, if any, for such event. 5.3 ISSUANCE OF COMMON STOCK. (a) General. If, at any time after the Closing Date, the Company shall issue or sell (or, in accordance with Section 5.3(b), shall be deemed to have issued or sold) any shares of Common Stock (other than any issuance for which an adjustment is made pursuant to Section 5.2 or 5.5) without consideration or for a consideration per share less than the Market Price for the Common Stock determined as of the date of such issuance or sale, then, effective immediately upon such issuance or sale, the Exercise Price and the number Warrant Shares issuable upon exercise of each Warrant shall be adjusted as follows: (i) The Exercise Price shall be reduced to an amount equal to the product obtained by multiplying (A) the Exercise Price in effect immediately prior to such issuance or sale times (B) a fraction, (I) the numerator of which shall be the sum of (x) the product of (1) the number of shares of Common Stock outstanding (on a Fully Diluted Basis) immediately prior to such issuance or sale times (2) the Market Price for the Common Stock as of the date of such issuance or sale plus (y) the consideration, if any, received by the Company upon such issuance or sale, and (II) the denominator of which shall be the product of (x) the number of shares of Common Stock outstanding (on a Fully Diluted Basis) immediately after such issuance or sale times (y) such Market Price; and (ii) The number of Warrant Shares issuable upon exercise of such Warrant shall be increased to the number of shares determined by multiplying (A) the number of Warrant Shares issuable upon exercise of such Warrant immediately prior to such issuance or sale by (B) a fraction, (1) the numerator of which shall be the Exercise Price in effect immediately prior to the adjustment in clause (i) of this Section 5.3(a), and -13- (2) the denominator of which shall be the Exercise Price in effect immediately after such adjustment; provided, however, that notwithstanding anything to the contrary set forth herein, the Exercise Price shall not be lower than the Floor Price. (b) Issuance of Options or Convertible Securities. The issuance or sale of Options or Convertible Securities shall be deemed, in accordance with this Section 5.3(b), to be the issuance of Common Stock. (i) Definitions. For the purposes of this Section 5.3(b), the term "OPTIONS" means any warrants, options or other rights to subscribe for or to purchase (A) Common Stock or (B) Convertible Securities, and the term "CONVERTIBLE SECURITIES" means any capital stock, evidence of indebtedness or other securities or rights convertible into or exchangeable for Common Stock. (ii) Issuance of Options. If the Company in any manner issues or grants any Options, then the total maximum number of shares of Common Stock issuable upon the exercise of such Options (or upon conversion or exchange of the total maximum amount of Convertible Securities issuable upon the exercise of such Options) shall be deemed, for purposes of Section 5.3(a), to be outstanding and to have been issued and sold by the Company. For purposes of Section 5.3(a), the Common Stock issuable upon exercise of Options or upon conversion or exchange of Convertible Securities issuable upon exercise of Options for Convertible Securities shall be deemed to have been issued and sold at a price per share equal to (A) the sum of (x) the total amount, if any, received or receivable by the Company as consideration for the issuance or granting of such Options plus (y) the minimum aggregate amount of additional consideration payable to the Company upon the exercise of all such Options plus (z) in the case of such Options for Convertible Securities, the minimum aggregate amount of additional consideration, if any, payable to the Company upon issuance or sale of such Convertible Securities and the conversion or exchange thereof divided by (B) the total maximum number of shares of Common Stock issuable upon exercise of such Options or upon the conversion or exchange of all such Convertible Securities issuable upon the exercise of such Options. (iii) Issuance of Convertible Securities. If the Company in any manner issues or sells any Convertible Securities, then the maximum number of shares of Common Stock issuable upon the conversion or exchange of such Convertible Securities shall be deemed, for purposes of Section 5.3(a) to be outstanding and to have been issued and sold by the Company. For purposes of Section 5.3(a), the Common Stock issuable upon conversion or exchange of Convertible Securities shall be deemed to have been issued and sold at a price per share equal to (A) the sum of (x) the total amount received or receivable by the Company as consideration for the issuance or sale of such Convertible Securities plus (y) the minimum aggregate amount of additional consideration, if any, payable to the Company upon the conversion or exchange thereof -14- divided by (B) the total maximum number of shares of Common Stock issuable upon the conversion or exchange of all such Convertible Securities. (iv) Superseding Adjustment. To the extent the Warrants have not been exercised, if, at any time after any adjustment of the Exercise Price and the number of Warrant Shares issuable upon exercise of the Warrants shall have been made pursuant to Section 5.3(a) as a result of the issuance of Options or Convertible Securities, or after any new adjustment of the Exercise Price and the number of Warrant Shares shall have been made pursuant to this Section 5.3(b)(iv) (each of the foregoing, a "PREVIOUS ADJUSTMENT"): (A) such Options or the right of conversion or exchange of such Convertible Securities shall expire, or be terminated or surrendered, and all or a portion of such Options or the right of conversion or exchange with respect to all or a portion of such Convertible Securities, as the case may be, shall not have been exercised or treated as having been exercised or otherwise canceled or acquired by the Company in connection with any settlement, including any cash settlement, of such Options or the rights of conversion or exchange of such Convertible Securities; or (B) there has been any change in the number of shares of Common Stock issuable upon the exercise of such Options or upon the conversion or exchange of such Convertible Securities (including as a result of a change in the number of Convertible Securities issuable upon the exercise of such Options or the operation of antidilution provisions applicable thereto); or (C) the consideration per share for which shares of Common Stock are issuable upon the exercise of such Options or upon the conversion or exchange of such Convertible Securities, or the maturity of such Convertible Securities, shall be changed; then the Previous Adjustment shall be rescinded and annulled and the shares of Common Stock which were deemed to have been issued and that gave rise to the Previous Adjustment shall no longer be deemed to have been issued. Thereupon, a recomputation shall be made of the adjustment, if any, of the Exercise Price and the number of Warrant Shares issuable upon exercise of the Warrants as a consequence of such Options or Convertible Securities on the basis of: (D) treating the number of shares of Common Stock, if any, theretofore actually issued or issuable pursuant to the previous exercise of such Options or such right of conversion or exchange (including Options or rights treated as exercised, otherwise cancelled or acquired in connection with any settlement), as having been issued on the date or dates of such issuance as determined for purposes of the Previous Adjustment and for the total amount of -15- consideration actually received and receivable therefor (determined in the manner described in Section 5.3(b)(ii) or (iii), as the case may be); (E) treating the maximum number of shares of Common Stock (1) issuable upon the exercise (or upon the conversion or exchange of Convertible Securities issuable upon the exercise) of all Options which then remain outstanding and (2) issuable upon the conversion or exchange of all Convertible Securities which then remain outstanding, as having been issued; and (F) making the computations called for in Section 5.3(a) hereof on the basis of the revised terms of such outstanding Options or Convertible Securities, as the case may be, as if they were newly issued at the time of such revision. Any adjustment of the Exercise Price and the number of Warrant Shares issuable upon exercise of the Warrants resulting from such recomputation shall supersede the Previous Adjustment. (v) No Further Adjustments. Any adjustment of the Exercise Price or the number of Warrant Shares issuable upon the exercise of Warrants to be made pursuant to this Section 5.3 with respect to the issuance of (A) any Options (whether for Common Stock or Convertible Securities), (B) any Convertible Securities issuable upon the exercise of such Options or (C) any shares of Common Stock issuable upon the exercise of such Options or the conversion or exchange of such Convertible Securities shall be made effective upon the issuance of such Options. Any adjustment of the Exercise Price or the number of Warrant Shares issuable upon the exercise of Warrants to be made pursuant to this Section 5.3 with respect to the issuance of (x) any Convertible Securities (other than Convertible Securities issuable upon the exercise of Options) or (y) any shares of Common Stock issuable upon the conversion or exchange of such Convertible Securities shall be made effective upon the issuance of such Convertible Securities. No further adjustment of the Exercise Price or the number of Warrant Shares issuable upon the exercise of Warrants shall be made upon the actual issuance of Common Stock or of Convertible Securities upon the exercise of such Options or upon the actual issuance of Common Stock upon conversion or exchange of Convertible Securities. 5.4 DISTRIBUTION OF EQUITY SECURITIES. If, at any time after the Closing Date, the Company shall distribute any of its equity securities or rights to acquire equity securities (other than Common Stock) to holders of Common Stock on a pro rata basis, then the Company shall cause effective provision to be made so that, effective as of the effective date of such event retroactive to the record date, if any, of such event, each Warrant shall, upon the basis and upon the terms and conditions specified in this Warrant, in addition to the Warrant Shares immediately theretofore purchasable and receivable upon the exercise of this Warrant, be exercisable for the kind and number of shares or other units of equity securities or rights to acquire equity securities to which a holder of the number of Warrant Shares issuable upon exercise of such Warrant would have been entitled had -16- such Warrant been exercised immediately prior to the record date of such event. In any such case, if necessary, the provisions of this Agreement and the Warrants with respect to the rights and interests thereafter of the Holders of the Warrants shall be appropriately adjusted so as to be applicable, as nearly as may reasonably be, to any shares or other units of equity securities or rights to acquire equity securities thereafter deliverable upon the exercise of the Warrants . 5.5 CAPITAL REORGANIZATION, CAPITAL RECLASSIFICATIONS, MERGER, ETC. If, at any time after the Closing Date, there shall be (i) any capital reorganization or any reclassification of the capital stock of the Company (other than a change in par value or from par value to no par value or from no par value to par value or as a result of a stock dividend or subdivision, split-up or combination of shares to which Section 5.2 applies or any distribution to which Section 5.4 applies), (ii) any consolidation, merger or business combination of the Company with another Person or (iii) any sale or conveyance by the Company of all or substantially all of its assets or property to, another Person, then in each case the transaction shall be effected in such a way that holders of the shares of Common Stock shall be entitled to receive stock, securities or assets (including, without limitation, cash) with respect to or in exchange for the shares of the Common Stock and the Company shall cause effective provision to be made so that each Warrant shall, upon the basis and upon the terms and conditions specified in this Warrant in lieu of the Warrant Shares immediately theretofore purchasable and receivable upon the exercise of this Warrant, effective as of the effective date of such event retroactive to the record date, if any, of such event, be exercisable for the kind and number of shares of stock, other securities, cash or other property to which a holder of the number of Warrant Shares issuable upon exercise of such Warrant would have been entitled upon such event. In any such case, if necessary, the provisions of this Agreement and the Warrants with respect to the rights and interests thereafter of the Holders of the Warrants shall be appropriately adjusted so as to be applicable, as nearly as may reasonably be, to any shares of stock, other securities, cash or other property thereafter deliverable upon the exercise of the Warrants. 5.6 OTHER ACTIONS AFFECTING COMMON STOCK. (a) Equitable Equivalent. If at any time or from time to time the Company shall take any action affecting its Common Stock, other than any action of a type otherwise described in this Article V (whether or not such action of a type otherwise described in this Article V results in an adjustment to the Warrants), then the number of Warrant Shares issuable upon exercise of each Warrant shall be adjusted to such extent, if any, and in such manner and at such time, as the Board shall in good faith determine to be equitable in the circumstances, provided that no such adjustment shall decrease the number of Warrant Shares issuable upon exercise of such Warrant and provided, further, that no adjustment shall be required for any cash dividends paid out of retained earnings. (b) No Avoidance. The Company will not, by amendment of its Articles of Incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the -17- Company; provided that the Company shall not be deemed to be avoiding or seeking to avoid observance or performance if any action otherwise in compliance with this Agreement is structured so as to avoid the need for, or to minimize the extent of any adjustment under this Article V. The Company shall at all times in good faith assist in the carrying out of all the provisions of this Article V and in the taking of all such action as may be necessary or appropriate in order to protect the exercise rights of the Holders against impairment. 5.7 MISCELLANEOUS. (a) Calculation of Consideration Received. If any Common Stock, Options, Convertible Securities or other securities are issued or sold or deemed to have been issued or sold for cash, then the consideration received therefor shall be deemed to be the net amount received by the Company therefor. If any Common Stock, Options, Convertible Securities or other securities are issued or sold for consideration other than cash, then the amount of the consideration other than cash received by the Company shall be the fair market value of such consideration, as of the date of receipt, determined in accordance with the Valuation Procedure. (b) Treasury Shares. The number of shares of Common Stock outstanding at any given time does not include shares owned or held by or for the account of the Company or any Subsidiary, and the disposition of any shares so owned or held shall be considered an issuance of Common Stock. (c) Record Date. If the Company takes a record of the holders of Common Stock for the purpose of entitling them (A) to receive a dividend or other distribution payable in Common Stock, Options or Convertible Securities or (B) to subscribe for or purchase Common Stock, Options or Convertible Securities, then such record date shall be deemed to be the date of the issuance or sale of the shares of Common Stock deemed to have been issued or sold upon the declaration of such dividend or the making of such other distribution or the date of the granting of such right of subscription or purchase, as the case may be. If the Company shall take any such record of the holders of its Common Stock and shall, thereafter and before the taking of the action for which such record was taken, legally abandon its plan to take such action, then thereafter no adjustment shall be required by reason of the taking of such record and any such adjustment previously made in respect thereof shall be rescinded and annulled. (d) Deferral of Issuance. In any case in which this Article V shall require that any adjustment in the number of Warrant Shares purchasable hereunder or in the Exercise Price be made effective as of immediately after a record date for a specified event, the Company may elect to defer, until the occurrence of such event, the issuing to the Holder of any Warrant exercised after such record date of the shares of Common Stock and other capital stock of the Company, if any, issuable upon such exercise over and above the number of shares of Common Stock and other capital stock of the Company, if any, that would have been issuable upon such exercise on the basis of the Exercise Price in effect prior to such adjustment. In such case, the Company shall deliver to the Holder a due bill or other appropriate instrument evidencing the Holder's right to receive such additional shares upon the occurrence of the event requiring such adjustment. -18- (e) Notice; Adjustment Rules. Whenever the Exercise Price and the number of Warrant Shares shall be adjusted as provided in this Article V, the Company shall provide to each Holder a statement, signed by the Chairman, the President or the Chief Financial Officer of the Company, describing in detail the facts requiring such adjustment and setting forth a calculation of the Exercise Price and the number of Warrant Shares applicable to each Warrant after giving effect to such adjustment. All calculations under this Article V shall be made to the nearest one hundredth of a cent ($.0001) or to the nearest one-tenth of a share, as the case may be. Adjustments pursuant to this Article V shall apply to successive events or transactions of the types covered thereby. Notwithstanding any other provision of this Article V, no adjustment shall be made to the number of shares of Common Stock or to the Exercise Price if such adjustment represents less than 1% of the number of shares previously required to be so delivered, but any lesser adjustment shall be carried forward and shall be made at the time and together with the next subsequent adjustment which together with any adjustments so carried forward shall amount to 1% or more of the number of shares to be so delivered. (f) Certain Adjustments. The Company may make such reductions in the Exercise Price or increase in the number of Warrant Shares to be received by any Holder upon the exercise or exchange of a Warrant, in addition to those adjustments required by this Article V, as it in its sole discretion shall determine to be advisable in order that any consolidation or subdivision of the Common Stock, or any issuance wholly for cash of any shares of Common Stock, or any issuance wholly for cash of shares of Common Stock or Convertible Securities, or any stock dividend, or any issuance of Options hereinafter made by the Company to the holders of its Common Stock shall not be taxable to such holders. (g) Excluded Issuances. Notwithstanding any other provision of this Article V, no adjustment shall be made pursuant to Section 5.3 or 5.5 in respect of: (i) the issuance of Common Stock in an underwritten public offering that is registered with the Commission, (ii) any securities issued upon conversion of the Series B Preferred Stock; (iii) any securities issued or granted to eligible officers, employees or directors of, or consultants to, the Corporation and its subsidiaries pursuant to any stock option, issuance, appreciation rights, restricted stock, phantom stock, stock purchase plan or other equity incentive plan for such persons (including without limitation, securities issued upon the exercise of such securities, but excluding any stock options that are not issued pursuant to a stock option plan or a stock purchase plan); (iv) any securities issued upon exercise of any warrants or options outstanding as of the Closing Date; (v) any securities issued to financial institutions in connection with debt financings; (vi) securities issuable under the Letter Agreement Regarding Participation in Carrizo 2001 Program dated as of May 1, 2001, among the Corporation, Berea Associates, LLC, Berea Oil & Gas Corp., PAC Finance (USA) Inc., William R. Ziegler, Thomas H. O'Neill, Jr. and Berea Associates II LLC, as in effect as of the Closing Date; (vii) the issuance of Common Stock or Options in any merger, share exchange, consolidation, liquidation or other business combination required to be approved and actually approved by the requisite vote (being not less than a majority based on voting power) of the shareholders of the Company; (viii) up to an aggregate of 500,000 shares of Common Stock issued after the Closing Date as consideration for any property acquisition, provided, however, that the Corporation shall be entitled to issue, as an excluded issuance -19- hereunder, additional shares of Common Stock for property acquisitions (in excess of such 500,000 shares) upon the prior written consent of Mellon Ventures L.P., which consent shall not be unreasonably withheld; or (ix) securities of the Corporation issued upon the conversion or exercise of other securities, which other securities of the Corporation had previously resulted in an adjustment hereunder (or which had, pursuant to the terms hereof, not required an adjustment). (h) Par Value. The Company shall not increase the par value of any shares of Common Stock or other securities issuable upon the exercise of the Warrants to an amount that exceeds the Exercise Price. Before taking any action that would cause an adjustment pursuant to this Article V that would reduce the Exercise Price below the par value per share of the Common Stock, the Company shall be required to take any corporate action which may 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. ARTICLE VI COVENANTS OF THE COMPANY 6.1 NOTICES OF CERTAIN ACTIONS. In the event that the Company: (a) shall authorize issuance to all holders of Common Stock of rights or warrants to subscribe for or purchase capital stock of the Company or of any other subscription rights or warrants; or (b) shall authorize a dividend or other distribution to all holders of Common Stock of evidences of its indebtedness, cash or other property or assets; or (c) becomes a party to any consolidation or merger for which approval of any shareholders of the Company will be required, or to a conveyance or transfer of the properties and assets of the Company substantially as an entirety, or of any capital reorganization or reclassification or change of the Common Stock (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 (d) commences a voluntary or involuntary dissolution, liquidation or winding up; or (e) takes any other action which would require an adjustment pursuant to Article V; -20- then the Company shall provide a written notice to each Holder stating (i) the date as of which the holders of record of Common Stock to be entitled to receive any such rights, warrants or distribution are to be determined, (ii) the material terms of any such consolidation or merger and the expected effective date thereof, or (iii) the material terms of any such conveyance, transfer, dissolution, liquidation or winding up and the expected effective date thereof, and the date as of which it is expected that holders of record of Common Stock will be entitled to exchange their shares for securities or other property, if any, deliverable upon such reclassification, conveyance, transfer, dissolution, liquidation or winding up. Such notice shall be given not later than seven (7) Business Days prior to the effective date (or the applicable record date, if earlier) of such event. The failure to give the notice required by this Section 7.1 or any defect therein shall not affect the legality or validity of any distribution, right, warrant, consolidation, merger, conveyance, transfer, dissolution, liquidation or winding up, or the vote upon any action. 6.2 MERGER OR CONSOLIDATION OF THE COMPANY. The Company will not merge or consolidate with or into, or sell, transfer or lease all or substantially all of its property (and such sale or transfer of property is effected in such a way that holders of the shares of Common Stock shall be entitled to receive stock, securities or assets (including, without limitation, cash) with respect to or in exchange for shares of the Common Stock) to any other entity unless the successor or purchasing entity expressly assumes, by supplemental agreement reasonably satisfactory in form and substance to the Requisite Holders, the due and punctual performance and observance of each and every covenant and condition of this Agreement to be performed and observed by the Company; provided, however, that the initial obligation of such successor with respect to the exercise of Warrants shall be only as set forth in Section 5.5, and provided, further, that if the successor or purchasing entity, as the case may be (if not the Company), is not organized under the laws of the United States of America or any state or political subdivision thereof and the Common Stock in such transaction is converted into the right to receive securities of such entity, such securities of such entity shall be marketable and freely tradable.

No Warrant shall entitle the holder thereof to any rights as a shareholder of the Company, as such, including, without limitation, voting rights, the right to call meetings, consent or receive notices as a shareholder in respect of any meeting or to the benefit of any fiduciary duty owed to a shareholder of the Company as such, all of which rights and duties are expressly disclaimed and waived by the Holder. No dividends are payable or will accrue on the Warrants or the Warrant Shares until, and except to the extent that, the Warrants are exercised. No provision hereof, in the absence of affirmative action by the Holder to purchase Warrant Shares, and no enumeration herein of the rights or privileges of the Holder shall give rise to any liability of such Holder for the Exercise Price of Warrant Shares acquirable by exercise hereof or as a shareholder of the Company. -22- 7.3 AMENDMENTS AND WAIVERS. (a) Written Document. Any provision of this Agreement may be amended or waived, but only pursuant to a written agreement signed by the Company and the Requisite Holders, provided that no such amendment or modification shall without the written consent of each Holder affected thereby (i) shorten the Expiration Date of any Warrant, (ii) increase the Exercise Price of any Warrant, (iii) change any of the provisions of this Section 7.3(a) or the definition of "Requisite Holders" or any other provision hereof specifying the number or percentage of Holders required to waive, amend or modify any rights hereunder or make any determination or grant any consent hereunder or otherwise act with respect to this Agreement or any Warrants or (iv) increase the obligations of any Holder or otherwise disproportionately adversely affect the rights and benefits of any Holder under this Agreement. (b) No Waiver; Cumulative Remedies. No failure on the part of any Holder to exercise and no delay in exercising, and no course of dealing with respect to, any right, power or privilege under this Agreement, the Warrants or the Registration Rights Agreement shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or privilege under this Agreement, the Warrant or the Registration Rights Agreement preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The remedies provided herein are cumulative and not exclusive of any remedies provided by law. 7.4 REMEDIES. (a) Each Holder shall have all rights and remedies reserved for such Holder pursuant to this Agreement and all rights and remedies which such Holder has been granted at any time under any other agreement or contract and all of the rights which such Holder has under any law or equity.

(b) The parties hereto agree that if any parties seek to resolve any dispute arising under this Agreement pursuant to a legal proceeding, the prevailing parties to such proceeding shall be entitled to receive reasonable fees and expenses (including reasonable attorneys' fees and expenses) incurred in connection with such proceedings. (c) It is acknowledged that it will be impossible to measure in money the damages that would be suffered by any party hereto if any Person also party hereto fails to comply with any of the obligations imposed upon them in this Agreement and that in the event of any such failure, the aggrieved party will be irreparably damaged and will not have an adequate remedy at law. Any such aggrieved party shall, therefore, be entitled to injunctive relief, including specific performance, to enforce such obligations, and if any action should be brought in equity to enforce any of the provisions of this Agreement, none of the parties hereto shall raise the defense that there is an adequate remedy at law. -23- 7.5 BINDING EFFECT. This Agreement shall be binding upon and inure to the benefit of the Company, each Holder and their respective successors and permitted assigns. 7.6 COUNTERPARTS. This Agreement may be executed in two or more counterparts each of which shall constitute an original but all of which when taken together shall constitute but one agreement. 7.7 GOVERNING LAW. THIS AGREEMENT AND EACH WARRANT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK (WITHOUT GIVING EFFECT TO PRINCIPLES OF CONFLICTS OF LAWS EXCEPT TO THE EXTENT THAT THE NEW YORK CONFLICTS OF LAWS PRINCIPLES WOULD APPLY THE APPLICABLE LAWS OF THE STATE OF TEXAS TO INTERNAL MATTERS RELATING TO CORPORATIONS ORGANIZED THEREUNDER). 7.8 BENEFITS OF THIS AGREEMENT. Nothing in this Agreement shall be construed to give to any Person other than the Company and each Holder of a Warrant or a Warrant Share any legal or equitable right, remedy or claim hereunder. 7.9 HEADINGS.
