Section 4. Exercise.

(a) Warrants in denominations of one or whole number multiples thereof may he exercised commencing at any time on or after the Initial Warrant Exercise Date, but not after the Warrant Expiration Date, upon the terms and subject to the conditions set forth herein (including the provisions set forth in Sections 4(b) and 5 hereof) and in the applicable Warrant Certificate. A Warrant shall be deemed to have been exercised immediately prior to the close of business on the Exercise Date, provided that the Warrant Certificate representing such Warrant, with the exercise form thereon duly executed by the Registered Holder thereof or his attorney duly authorized in writing, together with payment in cash or by check made payable to the Company, of an amount in lawful money of the United States of America equal to the applicable Purchase Price has been received in good funds by the Warrant Agent. The person entitled to receive the securities deliverable upon such exercise shall be treated for all purposes as the holder of such securities as of the close of business on the Exercise Date. As soon as practicable on or after the Exercise Date and in any event within five business days after having received authorization from the Company, the Warrant Agent on behalf of the Company shall cause to be issued to the person or persons entitled to receive the same a Common Stock certificate or certificates for the shares of Common Stock deliverable upon such exercise, and the Warrant Agent shall deliver the same to the person or persons entitled thereto. Upon the exercise of any Warrant, the Warrant Agent shall promptly notify the Company in writing of such fact and of the number of securities delivered upon such exercise and shall cause all payments of an amount in cash or by check made payable to the order of the Company, equal to the Purchase Price, to be deposited promptly in the Company's bank account.

(b) In addition to the method of payment set forth in Section 4(a) and in lieu of any cash payment required thereunder, the Registered Holder(s) of the Warrants shall have the right at any time and from time to time to exercise the Warrants in full or in part by surrendering shares of Common Stock or this Warrant in the manner and at the place specified in Section 4(a) as payment of the aggregate Purchase Price per share for the Warrants to be exercised. The number of Warrants or shares of Common Stock to be surrendered in payment of the aggregate Purchase Price for the Warrants to be exercised shall be determined by multiplying the number of Warrants to be exercised by the Purchase Price per share, and then dividing the product thereof by an amount equal to the Fair Market Value per share of Common Stock on the date that all documents and instruments required to be delivered or surrendered to the Company for exercise of the Warrant have been so delivered or surrendered.

(c) The Company shall not be required to issue fractional shares upon the exercise of Warrants. Warrants may only be exercised in such multiples as are required to permit the issuance by the Company of one or more whole shares. If one or more Warrants shall be presented for exercise at the same time by the same Registered Holder, the number of whole shares which shall be issuable upon such exercise thereof shall be computed on the basis of the aggregate number of shares purchasable on exercise of the Warrants so presented. If any fraction of a share would, except for the provisions provided herein, be issuable on the exercise of any Warrant (or specified portion thereof), the Company shall pay an amount in cash equal to such fraction multiplied by the then current Fair Market Value of a share of Common Stock.

Section 5. Reservation of Shares; Listing; Payment of Taxes; etc.

(a) The Company covenants that it will at all times reserve and keep available out of its authorized Common Stock, solely for the purpose of issue upon exercise of Warrants, such number of shares of Common Stock as shall then be issuable upon the exercise of all outstanding Warrants. The Company covenants that all shares of Common Stock which shall be issuable upon exercise of the

Warrants shall, at the time of delivery thereof, be duly and validly issued and fully paid and nonassessable and free from all preemptive or similar rights, taxes, liens and charges with respect to the issue thereof, and that upon issuance such shares shall be listed on each securities exchange, if any, on which the other shares of outstanding Common Stock of the Company are then listed.

(b) The Company 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 Company will file a registration statement under the federal securities laws or a post effective amendment, use its best efforts to cause the same to become effective and use its best efforts to keep such registration statement current while any of the Warrants are outstanding and deliver a prospectus which complies with Section 10(a)(3) of the Securities Act of 1933, as amended, (the "Act"), to the Registered Holder exercising the Warrant (except, if in the opinion of counsel to the Company, such registration is not required under the federal securities law or if the Company receives a letter from the staff of the Securities and Exchange Commission (the "Commission") stating that it would not take any enforcement action if such registration is not effected). The Company will use best efforts to obtain appropriate approvals or registrations under state "blue sky" securities laws. With respect to any such securities, however, Warrants may not be exercised by, or shares of Common Stock issued to, any Registered Holder in any state in which such exercise would be unlawful.

(c) The Company 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 of Common Stock upon exercise of the Warrants; provided, however, that if 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.

(d) The Warrant Agent is hereby irrevocably authorized as the Transfer Agent to requisition from time to time certificates representing shares of Common Stock or other securities required upon exercise of the Warrants, and the Company will comply with all such requisitions.

Section 6. Exchange and Registration of Transfer.

(a) Warrant Certificates may be exchanged for other Warrant Certificates representing an equal aggregate number of Warrants or may be transferred in whole or in part. Warrant Certificates to be so exchanged shall be surrendered to the Warrant Agent at its Corporate Office, and the Company shall execute and the Warrant Agent shall countersign, issue and deliver in exchange therefor the Warrant Certificate or Certificates which the Registered Holder making the exchange shall be entitled to receive.

(b) The Warrant Agent shall keep, at such office, books in which, subject to such reasonable regulations as it may prescribe, it shall register Warrant Certificates and the transfer thereof. Upon due presentment for registration of transfer of any Warrant Certificate at such office, the Company 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.

(c) With respect to any Warrant Certificates presented for registration or transfer, or for exchange or exercise, the subscription or exercise form, as the case may be, on the reverse thereof shall be duly endorsed or be accompanied by a written instrument of instruments or transfer and subscription, in form satisfactory to the Company and the Warrant Agent, duly executed by the Registered Holder thereof or his attorney duly authorized in writing.

(d) No service charge shall be made for any exchange or registration of transfer of Warrant Certificates. However, the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection therewith.

(e) All Warrant Certificates surrendered for exercise or for exchange shall be promptly canceled by the Warrant Agent.

(f) Prior to due presentment for registration or transfer thereof, the Company and the Warrant Agent may deem and treat the Registered Holder of any Warrant Certificate as the absolute owner thereof of each Warrant represented thereby (notwithstanding any notations of ownership or writing thereon made by anyone other than the Company 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 Company and the Warrant Agent of evidence satisfactory to them of the ownership of and the loss, theft, destruction or mutilation of any Warrant Certificate and (in the case of loss, theft or destruction) of indemnity satisfactory to them, and (in case of mutilation) upon surrender and cancellation thereof, the Company shall execute and the Warrant Agent shall countersign and deliver in lieu thereof a new Warrant Certificate representing an equal aggregate number of Warrants. Applicants for a substitute Warrant Certificate shall also comply with such other reasonable regulations and pay such other reasonable charges as the Warrant Agent may prescribe.

Section 8. Adjustment of Purchase Price and Number of Shares Deliverable.

(a) Except as hereinafter provided, in the event the Company 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 issuance, subdivision or combination being herein called a "Change of Shares"), then, and thereafter upon each further Change of Shares, the Purchase Price for the Warrants (whether or not the same shall be issued and outstanding) in effect immediately prior to such Change of Shares shall be changed to a price (including any applicable fraction of a cent to the nearest cent) determined by dividing (i) the sum of (A) the total number of shares of Common Stock outstanding immediately prior to such Change of Shares, multiplied by the Purchase Price in effect immediately prior to such Change of Shares and (B) the consideration, if any, received by the Company upon such sale, issuance, subdivision or combination, by (ii) the total number of shares of Common Stock immediately after issuance, subdivision or such Change of Shares; provided, however, that in no event shall the Purchase Price be adjusted pursuant to this computation to an amount in excess of the Purchase Price in effect immediately prior to such computation, except in the case of a combination of outstanding shares of Common Stock. For the purposes of any adjustment to be made in accordance with this Section 8(a), the Shares of Common Stock issuable by way of dividend or other distribution on any stock of the Company shall be deemed to have been issued immediately after the opening of business on the day following the record date for the determination of shareholders entitled to receive such dividend or other distribution and shall be deemed to have been issued without consideration.

(b) Upon each adjustment of the Purchase Price pursuant to this Section 8, the number of shares of Common Stock purchasable upon the exercise of each Warrant shall be the number derived by multiplying the number of shares of Common Stock purchasable immediately prior to such adjustment by the Purchase Price in effect prior to such adjustment and dividing the product so obtained by the applicable adjusted Purchase Price.

(c) In case of any reclassification or change of outstanding shares of Common Stock issuable upon exercise of the Warrants (other than a change in par value, or from par value to no par value, or from no par value to par value or as a result of a subdivision or combination), or in case of any

consolidation or merger of the Company with or into another corporation (other than a merger with a Subsidiary in which merger the Company is the continuing corporation and which does not result in any reclassification or change of the then outstanding shares of Common Stock or other capital stock issuable upon exercise of the Warrants (other than a change in par value, or from par value to no par value, or from no par value to par value or as a result of subdivision or combination)) or in case of any sale or conveyance to another corporation of the property of the Company as an entity, then, as a condition of such reclassification, change, consolidation, merger, sale or conveyance, the Company, or such successor or purchasing corporation, as the case may be, shall make lawful and adequate provision whereby the Registered Holder of each Warrant then outstanding shall have the right thereafter to receive on exercise of such Warrant the kind and amount of securities and property receivable upon such reclassification, change, consolidation, merger, sale or conveyance by a holder of the number of securities issuable upon exercise of such Warrant immediately prior to such reclassification, change, consolidation, merger, sale or conveyance and shall forthwith file at the Corporate Office of the Warrant Agent a statement signed by its President or a Vice President and by its Treasurer or an Assistant Treasurer or its Secretary or an Assistant Secretary evidencing such provision. Such provisions shall include provision for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in Section 8(a) and (b). The above provisions of this Section 8(c) shall similarly apply to successive reclassifications and changes of shares of Common Stock and to successive consolidations, mergers, sales or conveyances.

(d) Irrespective of any adjustments or changes in the Purchase 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 Company shall exercise its option to issue new Warrant Certificates pursuant to Section 2(e) hereof, continue to express the Purchase Price per share and the number of shares purchasable thereunder as the Purchase Price per share.

(e) After each adjustment of the Purchase Price pursuant to this Section 8 or pursuant to Section 9, the Company 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 Company setting forth: (i) the Purchase Price as so adjusted, (ii) the number of shares of Common Stock purchasable upon exercise of each Warrant, after such adjustment, and (iii) a brief statement of the facts accounting for such adjustment. The Company 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 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 except as the Registered Holder to whom the Company failed to mail such notice, or except as to the Registered Holder whose notice was defective. The affidavit of an officer of the Warrant Agent or the Secretary or an Assistant Secretary of the Company that such notice has been mailed shall, in the absence of fraud, be prima facie evidence of the facts stated therein.

(f) No adjustment of the Purchase Price shall be made as a result of or in connection with (i) the issuance of Excluded Stock, or (ii) the issuance or sale of shares of Common Stock if the amount of said adjustment shall be less than $.01, provided, however, that in such case, any adjustment that would otherwise be required then to be made shall be carried forward and shall be made at the time of and together with the next subsequent adjustment that shall amount, together with any adjustment so carried forward, to at least $.01. In addition, Registered Holders shall not be entitled to cash dividends paid by the Company prior to the exercise of any Warrant or Warrants held by them.

Section 9. Intentionally Omitted.

Section 10. Concerning the Warrant Agent.

(a) The Warrant Agent acts hereunder as agent and in a ministerial capacity for the Company and the Underwriters, 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 or 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.

(b) 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 Purchase Price provided in this Agreement, or to determine whether any fact exists which may require any such adjustment, 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. It shall not (i) be liable for any recital or statement of fact contained herein or for any action taken, suffered or omitted by it in reliance on any Warrant Certificate or other document or instrument believed by it in good faith to be genuine and to have been signed or presented by the proper party or parties, (ii) be responsible for any failure on the part of the Company to comply with any of its covenants and obligations contained in this Agreement or in any Warrant Certificate, or (iii) be liable for any act or omission in connection with this Agreement except for its own gross negligence or willful misconduct.

(c) The Warrant Agent may at any time consult with counsel satisfactory to it (who may be counsel for the Company) and shall incur no liability or responsibility for any action taken, suffered or omitted by it in good faith in accordance with the opinion or advice of such counsel.

(d) Any notice, statement, instruction, request, direction, order or demand of the Company shall be sufficiently evidenced by an instrument signed by the Chairman of the Board of Directors, President or any Vice President (unless other evidence in respect thereof is herein specifically prescribed). The Warrant Agent shall not be liable for any action taken, suffered or omitted by it in accordance with such notice, statement, instruction, request, direction, order or demand.

(e) The Company agrees to pay the Warrant Agent reasonable compensation for its services hereunder and to reimburse it for its reasonable expenses hereunder; the Company further agrees to indemnify the Warrant Agent and save it harmless against any and all losses, expenses and liabilities, including judgments, costs and counsel fees, for anything done or omitted by the Warrant Agent in the execution of its duties and powers hereunder except losses, expenses and liabilities arising as a result of the Warrant Agent's gross negligence or willful misconduct.

(f) The Warrant Agent may resign its duties and be discharged from all further duties and liabilities hereunder (except liabilities arising as a result of the Warrant Agent's own gross negligence or willful misconduct), after giving 30 days' prior written notice to the Company. At least 15 days prior to the date such resignation is to become effective, the Warrant Agent shall cause a copy of such notice of resignation to be mailed to the Registered Holder of each Warrant Certificate at the Company's expense. Upon such resignation the Company shall appoint in writing a new warrant agent. If the Company shall fail to make such appointment within a period of 30 days after it has been notified in writing of such resignation by the resigning Warrant Agent, then the Registered Holder of any Warrant Certificate may apply to any court of competent jurisdiction for the appointment of a new warrant agent. Any new warrant agent, whether appointed by the Company or by such a court, shall be a bank or trust company having a capital and surplus, as shown by its last published report to its stockholders, of not less than $10,000,000 or a stock transfer company doing business in New York. After acceptance in writing of such appointment by the new warrant agent is received by the Company, such new warrant agent shall be vested with the same powers, rights, duties and responsibilities as if it had been originally named herein as the warrant agent, without any further assurance, conveyance, act or deed; but if for any reason it shall be necessary or expedient to execute and deliver any further assurance, conveyance, act or deed, the same shall be done at the expense of the Company and shall be legally and validly executed and delivered by the resigning Warrant Agent. Not later than the effective date of any such appointment the Company 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.

(g) Any corporation into which the Warrant Agent or any new warrant agent may be converted or merged, any corporation resulting from any consolidation to which the Warrant Agent or any new warrant agent shall be a party, or any corporation succeeding to the corporate trust business of the Warrant Agent or any new warrant agent shall be a successor warrant agent under this Agreement without any further act, provided that such corporation is eligible for appointment as successor to the Warrant Agent under the provisions of the preceding paragraph. Any such successor warrant agent shall promptly cause notice of its succession as warrant agent to be mailed to the Company and to the Registered Holders of each Warrant Certificate.

(h) The Warrant Agent, its subsidiaries and affiliates, and any of its or their officers or directors, may buy and hold or sell Warrants or other securities of the Company and otherwise deal with the Company in the same manner and to the same extent and with like effect as though it were not Warrant Agent. Nothing herein shall preclude the Warrant Agent from acting in any other capacity for the Company or for any other legal entity.
