(b) The Corporation covenants that if the issuance of any Warrants hereunder require registration with, or approval of, any governmental authority under any federal securities law before such Warrants may be validly delivered upon such issuance, then the Corporation will in good faith and as expeditiously as reasonably possible, endeavor to secure such registration or approval. The Corporation will use reasonable efforts to obtain appropriate approvals or registrations with respect to such Warrants under the "blue sky" securities laws of those states with respect to which the Corporation obtained a qualification in connection with its offering. (c) The Corporation covenants that if any securities to be reserved for the purpose of exercise of Warrants hereunder require registration with, or approval of, any governmental authority under any federal securities law before such securities may be validly issued or delivered upon such exercise, then the Corporation will in good faith and as expeditiously as reasonably possible, endeavor to secure such registration or approval.

However, Warrants may not be exercised or sold by, or shares of Common Stock issued to, any Registered Holder in any state in which such exercise or sale would be unlawful. -4- (d) The Corporation shall pay all documentary, stamp or similar taxes and other governmental charges that may be imposed with respect to the issuance of Warrants, or the issuance or delivery of any shares upon exercise of the Warrants; provided, however, that if the shares of Common Stock are to be delivered in a name other than the name of the Registered Holder of the Warrant Certificate representing any Warrant being exercised, then no such delivery shall be made unless the person requesting the same has paid to the Warrant Agent the amount of transfer taxes or charges incident thereto, if any. (e) The Warrant Agent is hereby irrevocably authorized to requisition the Corporation's Transfer Agent from time to time for certificates representing shares of Common Stock required upon exercise of the Warrants, and the Corporation will authorize the Transfer Agent to comply with all such proper requisitions. The Corporation will file with the Warrant Agent a statement setting forth the name and address of the Transfer Agent of the Corporation for shares of Common Stock issuable upon exercise of the Warrants, unless the Warrant Agent and the Transfer Agent are the same entity.

(b) The Warrant Agent shall keep at its office books in which, subject to such reasonable regulations as it may prescribe, it shall register Warrant Certificates and the transfer thereof in accordance with its regular practice. Upon due presentment for registration of transfer of any Warrant Certificate at such office, the Corporation shall execute and the Warrant Agent shall issue and deliver to the transferee or transferees a new Warrant Certificate or Certificates representing an equal aggregate number of Warrants of the same class. (c) With respect to all Warrant Certificates presented for registration of transfer, or for exchange or exercise, the subscription form on the reverse thereof shall be duly endorsed, or be accompanied by a written instrument or instruments of transfer and subscription, in form satisfactory to the Corporation and the Warrant Agent, duly executed by the Registered Holder or his attorney-in-fact duly authorized in writing. (d) A service charge may be imposed by the Warrant Agent against a Registered Holder for any exchange or registration of transfer of Warrant Certificates.

(f) Prior to due presentment for registration of transfer thereof, the Corporation and the Warrant Agent may deem and treat the Registered Holder of any Warrant Certificate as the absolute owner thereof and of each Warrant represented thereby (notwithstanding any notations of ownership or writing thereon made by anyone other than a duly authorized officer of the Corporation or the Warrant Agent) for all purposes and shall not be affected by any notice to the contrary. SECTION 7. Loss or Mutilation. Upon receipt by the Corporation and the ------------------ Warrant Agent of evidence satisfactory to them of the ownership of and loss, theft, destruction or mutilation of any Warrant Certificate and (in case of loss, theft or destruction) of indemnity satisfactory to them, and (in the case of mutilation) upon surrender and cancellation thereof, the Corporation shall execute and the Warrant Agent shall (in the absence of notice to the Corporation and/or Warrant Agent that the Warrant Certificate has been acquired by a bonafide purchaser) countersign and deliver to the Registered Holder in lieu thereof a new Warrant Certificate of like tenor representing an equal aggregate number of Warrants. Applicants for a substitute Warrant Certificate shall comply with such other reasonable regulations, provide such reasonable indemnification and pay such other reasonable charges as the Warrant Agent or the Corporation may prescribe. SECTION 8. Adjustment of Exercise Price and Number of Shares of Common ----------------------------------------------------------- Stock or Warrants. ----------------- (a) Subject to the exceptions referred to in Section 8(g) below, in the event the Corporation shall, at any time or from time to time after the date hereof, issue any shares of Common Stock as a stock dividend to the holders of Common Stock, or subdivide or combine the outstanding shares of Common Stock into a greater or lesser number of shares (any such sale, issuance, subdivision or combination being herein called a "Change of Shares"), then, and thereafter upon each further Change of Shares, the applicable Warrant Price in effect immediately prior to such Change of Shares shall be changed to a price (including any applicable fraction of a cent) determined by multiplying the Warrant Price in effect immediately prior thereto by a fraction, the numerator of which shall be the sum of (a) the total number of shares of Common Stock outstanding immediately prior to such Change of Shares and (b) the number of shares of Common Stock which the aggregate consideration received by the Corporation upon such sale, issuance, subdivision or combination (determined in accordance with subsection (e) below) could have purchased at the then current Warrant Price, and the denominator of which shall be the total number of shares of Common Stock outstanding immediately after such Change of Shares. Upon each adjustment of the applicable Warrant Price Pursuant to this Section 8, the total number of shares of Common Stock purchasable upon the exercise of each Warrant shall (subject to the provisions contained in Section 8(b) hereof) be such number of shares (calculated to the nearest hundredth) purchasable at the applicable Warrant Price immediately prior to such adjustment -6- multiplied by a fraction, the numerator of which shall be the applicable Warrant Price in effect immediately prior to such adjustment and the denominator of which shall be the applicable Warrant Price in effect immediately after such adjustment. (b) In case of any reclassification or capital reorganization of outstanding shares of Common Stock, or in case of any consolidation or merger of the Corporation with or into another corporation (other than a consolidation or merger in which the Corporation is the continuing corporation and which does not result in any reclassification or capital reorganization of outstanding shares of Common Stock) , or in case of any sale or conveyance to another corporation of the property of the Corporation as, or substantially as, an entirety (other than a sale/leaseback, mortgage or other financing transaction) , the Corporation shall cause effective provision to be made so that each holder of a Warrant then outstanding shall, in substitution for all rights theretofore represented by such Warrant, have the right thereafter, by exercising such Warrant, to purchase the kind and number of shares of stock or other securities or property (including cash) receivable upon such reclassification or capital reorganization, consolidation, merger, sale or conveyance by a holder of the number of shares of Common Stock that might have been purchased upon exercise of such Warrant, immediately prior to such reclassification or capital reorganization, consolidation, merger, sale or conveyance. Any such provision shall include provision for adjustments that shall be as nearly equivalent as may be practicable to the adjustments provided for in this Section 8. The foregoing provisions shall similarly apply to successive reclassifications or capital reorganizations of outstanding shares of Common Stock and to successive consolidations, mergers, sales or conveyances. (c) Irrespective of any adjustments or changes in the Warrant Price or the number of shares of Common Stock purchasable upon exercise of the Warrants, the Warrant Certificates theretofore and thereafter issued shall, unless the Corporation shall exercise its option to issue new Warrant Certificates pursuant to Section 2(c) hereof, continue to express the applicable Warrant Price per share and the number of shares purchasable thereunder as were expressed in the Warrant Certificates when the same were originally issued. (d) After each adjustment of the Warrant Price pursuant to this Section 8, the Corporation will promptly prepare a certificate signed by the Chairman or President, and by the Treasurer or an Assistant Treasurer or the Secretary or an Assistant Secretary, of the Corporation setting forth: (i) the applicable Warrant Price as so adjusted, (ii) the number of shares of Common Stock purchasable upon exercise of each Warrant after such adjustment, and, if the Corporation shall have elected to adjust the number of Warrants, the number of Warrants to which the registered holder of each warrant shall then be entitled, and (iii) a brief statement of the facts accounting for such adjustment. The Corporation will promptly file such certificate with the Warrant Agent and cause a brief summary thereof to be sent by ordinary first class mail to each Registered Holder of Warrants at his last address as it shall appear on the registry books of the Warrant Agent. No failure to mail such notice nor any defect therein or in the mailing thereof shall affect the validity thereof. The affidavit of an officer of the Warrant Agent or the Secretary or an Assistant Secretary of the Corporation that such notice has been mailed shall, in the absence of fraud, be prima facie evidence of the facts stated therein. -7- (e) For purposes of Section 8(a) and 8(b) hereof, the following provisions (A) and (B) shall also be applicable; (A) The number of shares of Common Stock outstanding at any given time shall include shares of Common Stock owned or held by or for the account of the Corporation and the sale or issuance of such treasury shares or the distribution of any such treasury shares shall not be considered a Change of Shares for purposes of said sections. (B) No adjustment of the Warrant Price shall be made unless such adjustment would require an increase or decrease of at least $.01 in such price; provided that any adjustments which by reason of this clause (B) are not required to be made shall be carried forward and shall be made at the time of and together with the next subsequent adjustment which, together with any adjustment(s) so carried forward, shall require an increase or decrease of at least $.01 in the Warrant Price then in effect hereunder. (f) As used in this Section 8, the term "Common Stock" shall mean and include the Corporation's Common Stock authorized on the date of the original issue of the Warrants and shall also include any capital stock of any class of the Corporation thereafter authorized which shall not be limited to a fixed sum or percentage in respect of the rights of the holders thereof to participate in dividends and in the distribution of assets upon the voluntary liquidation, dissolution or winding up of the Corporation; provided, however, that the shares issuable upon exercise of the Warrants shall include only shares of such class designated in the Corporation's Certificate of Incorporation as Common Stock on the date of the original issue of the Warrants or (i), in the case of any reclassification, change, consolidation, merger, sale or conveyance of the character referred to in Section 8(c) hereof, the stock, securities or property provided for in such section or (ii), in the case of any reclassification or change in the outstanding shares of Common Stock issuable upon exercise of the Warrants as a result of a subdivision or combination or consisting of a change in par value, or from par value to no par value, or from no par value to par value, such shares of Common Stock as so reclassified or changed. (g) Any determination as to whether an adjustment in the Warrant Price in effect hereunder is required pursuant to Section 8, or as to the amount of any such adjustment, if required, shall be binding upon the holders of the Warrants and the Corporation if made in good faith by the Board of Directors of the Corporation. SECTION 9. Fractional Warrants and Fractional Shares. ----------------------------------------- (a) If the number of shares of Common Stock purchasable upon the exercise of each Warrant is adjusted pursuant to Section 8 hereof, the Corporation shall nevertheless not be required to issue fractions of shares, upon exercise of the Warrants or otherwise, or to distribute certificates that evidence fractional shares or Warrants to purchase fractional shares. With respect to any fraction of a share called for upon any exercise hereof, the Corporation shall pay to the Registered Holder an amount in cash equal to such fraction multiplied by the current market value of such fractional share, determined as follows: -8- (1) If the Common Stock is listed on a National Securities Exchange or admitted to unlisted trading privileges on such exchange or listed for trading on the NASDAQ System, the current value shall be the last reported sale price of the Common Stock on such exchange or system on the last business day prior to the date of exercise of the Warrant or if no such sale is made on such day, the average of the closing bid and asked prices for such day on such exchange or system; or (2) If Section 9(a)(1) does not apply, the current value shall be the mean of the last reported bid and asked prices reported by the National Quotation Bureau, Inc. on the last business day prior to the date of the exercise of the Warrant; or (3) If neither Section 9(a)(1) nor Section 9(a)(2) applies, the current value shall be an amount determined in such reasonable manner as may be prescribed by the Board of Directors of the Corporation. SECTION 10. Warrant Holders Not Deemed Stockholders. No holder of --------------------------------------- Warrants shall, as such, be entitled to vote or to receive dividends or be deemed the holder of Common Stock that may at any time be issuable upon exercise of such Warrants for any purpose whatsoever, nor shall anything contained herein be construed to confer upon the holder of Warrants, as such, any of the rights of a stockholder of the Corporation or any right to vote for, or receive notice as a stockholder in respect of, the election of directors or upon any matter submitted to stockholders at any meeting thereof, or to give or withhold consent to any corporate action (whether upon any recapitalization, issue or reclassification of stock, change of par value or change of stock to no par value, consolidation, merger or conveyance or otherwise) or any other matter, or to receive notice of meetings, or to receive dividends or subscription rights, until such Holder shall have exercised such Warrants and been issued shares of Common Stock in accordance with the provisions hereof.

SECTION 12. Agreement of Warrant Holders. Every holder of a Warrant, by ---------------------------- his acceptance thereof, consents and agrees with the Corporation, the Warrant Agent and every other holder of a Warrant that: (a) The Warrants are transferable only on the registry books of the Warrant Agent by the Registered Holder thereof in person or by his attorney duly authorized in writing and only if the Warrant Certificates representing such Warrants are surrendered the office of the Warrant Agent, duly endorsed or accompanied a proper instrument of transfer satisfactory to the Warrant Agent and the Corporation in their sole discretion, together with payment of any applicable transfer taxes; and -9- (b) The Corporation and the Warrant Agent may deem and treat the Person in whose name the Warrant Certificate is registered as the holder and as the absolute, true and lawful owner of the Warrants represented thereby for all purposes, and neither the Corporation nor the Warrant Agent shall be affected by any notice or knowledge to the contrary, except as otherwise expressly provided in Section 7 hereof.

The Warrant Agent acts ---------------------------- hereunder as agent and in a ministerial capacity for the Corporation, and its duties shall be determined solely by the provisions hereof. The Warrant Agent shall not, by issuing and delivering Warrant Certificates or by any other act hereunder be deemed to make any representations as to the validity, value or authorization of the Warrant Certificates or the Warrants represented thereby or of any securities or other property delivered upon exercise of any Warrant or whether any stock issued upon exercise of any Warrant is fully paid and nonassessable. The Warrant Agent shall not at any time be under any duty or responsibility to any holder of Warrant Certificates to make or cause to be made any adjustment of the Warrant Price provided in this Agreement, or to determine whether any fact exists which may require any such adjustments, or with respect to the nature or extent of any such adjustment, when made, or with respect to the method employed in making the same.

Not later than the effective date of any such appointment the Corporation shall file notice thereof with the resigning Warrant Agent and shall forthwith cause a copy of such notice to be mailed to the Registered Holder of each Warrant Certificate.
