Exercise of Warrant. ------------------- (a) Subject to the terms and conditions hereof, this Warrant may be exercised by the holder hereof then registered on the books of the Company, in whole or in part, at any time on any Business Day on or after the opening of business on the date hereof and prior to 11:59 P.M. Eastern Time on the Expiration Date by (i) delivery of a written notice, in the form of the subscription notice attached as Exhibit A hereto (the "Exercise Notice"), of --------- such holder's election to exercise this Warrant, which notice shall specify the number of Warrant Shares to be purchased, (ii) (A) payment to the Company of an amount equal to the applicable Warrant Exercise Price multiplied by the number of Warrant Shares as to which this Warrant is being exercised (plus any applicable issue or transfer taxes) (the "Aggregate Exercise Price") in cash or wire transfer of immediately available funds or (B) by notifying the Company that this Warrant is being exercised pursuant to a Cashless Exercise (as defined in Section 2(e)) and (iii) the surrender to a common carrier for overnight delivery to the Company as soon as practicable following such date, this Warrant (or an indemnification undertaking with respect to this Warrant in the case of its loss, theft or destruction); provided, that if such Warrant Shares are to be issued in any name other than that of the registered holder of this Warrant, such issuance shall be deemed a transfer and the provisions of Section 7 shall be applicable. In the event of any exercise of the rights represented by this Warrant in compliance with this Section 2(a), the Company shall on the second Business Day following the date of receipt of the Exercise Notice, the Aggregate Exercise Price (or notice of a Cashless Exercise) and this Warrant (or an indemnification undertaking with respect to this Warrant in the case of its loss, theft or destruction) (the "Exercise Delivery Documents"), credit such aggregate number of shares of Common Stock to which the holder shall be entitled to the holder's or its designee's balance account with The Depository Trust Company; provided, however, if the holder who submitted the Exercise Notice requested physical delivery of any or all of the Warrant Shares and such shares cannot be delivered via the Depository Trust Company, then the Company shall, on or before the second Business Day following receipt of the Exercise Delivery Documents issue and surrender to a common carrier for overnight delivery to the address specified in the Exercise Notice, a certificate, registered in the name of the holder, -5- for the number of shares of Common Stock to which the holder shall be entitled pursuant to such request. Upon delivery of the Exercise Notice and Aggregate Exercise Price referred to in clause (ii)(A) above or notification to the Company of a Cashless Exercise referred to in Section 2(e), the holder of this Warrant shall be deemed for all corporate purposes to have become the holder of record of the Warrant Shares with respect to which this Warrant has been exercised, irrespective of the date of delivery of this Warrant as required by clause (iii) above or the certificates evidencing such Warrant Shares. In the case of a dispute as to the determination of the Warrant Exercise Price, the Closing Sale Price or the Closing Bid Price of a security or the arithmetic calculation of the Warrant Shares, the Company shall promptly issue to the holder the number of shares of Common Stock that is not disputed and shall submit the disputed determinations or arithmetic calculations to the holder via facsimile within one Business Day of receipt of the holder's subscription notice. If the holder and the Company are unable to agree upon the determination of the Warrant Exercise Price, the Closing Sale Price or Closing Bid Price or arithmetic calculation of the Warrant Shares within one day of such disputed determination or arithmetic calculation being submitted to the holder, then the Company shall immediately submit via facsimile (i) the disputed determination of the Warrant Exercise Price, Closing Sale Price or the Closing Bid Price to an independent, reputable investment banking firm or (ii) the disputed arithmetic calculation of the Warrant Shares to its independent, outside accountant. The Company shall cause the investment banking firm or the accountant, as the case may be, to perform the determinations or calculations and notify the Company and the holder of the results no later than two (2) Business Days from the time it receives the disputed determinations or calculations. Such investment banking firm's or accountant's determination or calculation, as the case may be, shall be deemed conclusive absent manifest error. (b) Unless the rights represented by this Warrant shall have expired or shall have been fully exercised, the Company shall, as soon as practicable and in no event later than five Business Days after any exercise and at its own expense, issue a new Warrant identical in all respects to the Warrant exercised except it shall represent rights to purchase the number of Warrant Shares purchasable immediately prior to such exercise under the Warrant exercised, less the number of Warrant Shares with respect to which such Warrant is exercised. (c) No fractional shares of Common Stock are to be issued upon the exercise of this Warrant, but rather the number of shares of Common Stock issued upon exercise of this Warrant shall be rounded up or down to the nearest whole number. (d) Intentionally left blank. -6- (e) Notwithstanding anything contained herein to the contrary and in addition to and not in lieu of any of the other rights and remedies to which the holder may be entitled by reason of the Company's failure fully to meet its obligations under the Securities Purchase Agreement or the Registration Rights Agreement, the holder of this Warrant may, at its election exercised in its sole discretion, exercise this Warrant in whole or in part and, in lieu of making the cash payment otherwise contemplated to be made to the Company upon such exercise in payment of the Aggregate Exercise Price, elect instead to receive upon such exercise the "Net Number" of shares of Common Stock determined according to the following formula (a "Cashless Exercise"): Net Number = (A x B) - (A x C) ----------------- B For purposes of the foregoing formula: A= the total number shares with respect to which this Warrant is then being exercised. B= the Closing Sale Price of the Common Stock on the date immediately preceding the date of the subscription notice. C= the Warrant Exercise Price then in effect for the applicable Warrant Shares at the time of such exercise. Section 3. Covenants as to Common Stock. The Company hereby covenants and ---------------------------- agrees as follows: (a) This Warrant is, and any Warrants issued in substitution for or replacement of this Warrant will upon issuance be, duly authorized and validly issued. (b) All Warrant Shares which may be issued upon the exercise of the rights represented by this Warrant in conformity with the terms of this Warrant will, upon issuance, be validly issued, fully paid and nonassessable and free from all taxes, liens and charges with respect to the issue thereof. -7- (c) During the period within which the rights represented by this Warrant may be exercised, the Company will at all times have authorized and reserved at least 100% of the number of shares of Common Stock needed to provide for the exercise of the rights then represented by this Warrant and the par value of said shares will at all times be less than or equal to the applicable Warrant Exercise Price. (d) The Company shall promptly secure the listing of the shares of Common Stock issuable upon exercise of this Warrant upon each national securities exchange or automated quotation system, if any, upon which shares of Common Stock are then listed (subject to official notice of issuance upon exercise of this Warrant) and shall maintain, so long as any other shares of Common Stock shall be so listed, such listing of all shares of Common Stock from time to time issuable upon the exercise of this Warrant; and the Company shall so list on each national securities exchange or automated quotation system, as the case may be, and shall maintain such listing of, any other shares of capital stock of the Company issuable upon the exercise of this Warrant if and so long as any shares of the same class shall be listed on such national securities exchange or automated quotation system. (e) The Company will not, by amendment of its Certificate 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 by it hereunder, but will at all times in good faith assist in the carrying out of all the provisions of this Warrant and in the taking of all such action as may reasonably be requested by the holder of this Warrant in order to protect the exercise privilege of the holder of this Warrant against dilution or other impairment, consistent with the tenor and purpose of this Warrant. No impairment of the preferences and rights contained in the Company's Notes or any waiver thereof which has an adverse effect on the rights granted hereunder shall be given effect until the Company has taken appropriate action (satisfactory to the holders of Note Warrants representing a majority of the shares of Common Stock issuable upon the exercise of such Note Warrants then outstanding) to avoid such adverse effect with respect to this Warrant. Without limiting the generality of the foregoing, the Company (i) will not increase the par value of any shares of Common Stock receivable upon the exercise of this Warrant above the Warrant Exercise Price then in effect, and (ii) will take all such actions as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable shares of Common Stock upon the exercise of this Warrant. (f) This Warrant will be binding upon any entity succeeding to the Company by merger, consolidation or acquisition of all or substantially all of the Company's assets. Section 4. Taxes. The Company shall pay any and all taxes which may be ----- payable with respect to the issuance and delivery of Warrant Shares upon exercise of this Warrant (but no income, capital gain, estate or other taxes applicable to the holder resulting from any profits realized upon such exercise); 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 issue or delivery of Common Stock or other securities or property in a name other than that of the registered holders -8- of this Warrant to be converted and such holder shall pay such amount, if any, to cover any applicable transfer or similar tax. Section 5. Warrant Holder Not Deemed a Stockholder. Except as otherwise --------------------------------------- specifically provided herein, no holder, as such, of this Warrant shall be entitled to vote or receive dividends or be deemed the holder of shares of the Company for any purpose, nor shall anything contained in this Warrant be construed to confer upon the holder hereof, as such, any of the rights of a stockholder of the Company or any right to vote, give or withhold consent to any corporate action (whether any reorganization, issue of stock, reclassification of stock, consolidation, merger, conveyance or otherwise), receive notice of meetings, receive dividends or subscription rights, or otherwise, prior to the issuance to the holder of this Warrant of the Warrant Shares which he or she is then entitled to receive upon the due exercise of this Warrant. In addition, nothing contained in this Warrant shall be construed as imposing any liabilities on such holder to purchase any securities (upon exercise of this Warrant or otherwise) or as a stockholder of the Company, whether such liabilities are asserted by the Company or by creditors of the Company. Notwithstanding this Section 5, the Company will provide the holder of this Warrant with copies of the same notices and other information given to the stockholders of the Company generally, contemporaneously with the giving thereof to the stockholders. Section 6. Representations of Holder. The holder of this Warrant, by the ------------------------- acceptance hereof, represents that it is acquiring this Warrant and the Warrant Shares for its own account for investment only and not with a view towards, or for resale in connection with, the public sale or distribution of this Warrant or the Warrant Shares, except pursuant to sales registered or exempted under the Securities Act; provided, however, that by making the representations herein, the holder does not agree to hold this Warrant or any of the Warrant Shares for any minimum or other specific term and reserves the right to dispose of this Warrant and the Warrant Shares at any time in accordance with or pursuant to a registration statement or an exemption under the Securities Act. The holder of this Warrant further represents, by acceptance hereof, that, as of this date, such holder is an "accredited investor" as such term is defined in Rule 501(a)(1) of Regulation D promulgated by the Securities and Exchange Commission under the Securities Act (an "Accredited Investor"). Upon exercise of this Warrant, other than pursuant to a Cashless Exercise the holder shall, if requested by the Company, confirm in writing, in a form satisfactory to the Company, that the Warrant Shares so purchased are being acquired solely for the holder's own account and not as a nominee for any other party, for investment, and not with a view toward distribution or resale and that such holder is an Accredited Investor. If such holder cannot make such representations because they would be factually incorrect, it shall be a condition to such holder's exercise of this Warrant that the Company receive such other representations as the Company considers reasonably necessary to assure the Company that the issuance of its securities upon exercise of this Warrant shall not violate any United States or state securities laws. Section 7. Ownership and Transfer. ---------------------- (a) The Company shall maintain at its principal executive offices (or such other office or agency of the Company as it may designate by notice to the holder hereof), a register for -9- this Warrant, in which the Company shall record the name and address of the person in whose name this Warrant has been issued, as well as the name and address of each transferee. The Company may treat the person in whose name any Warrant is registered on the register as the owner and holder thereof for all purposes, notwithstanding any notice to the contrary, but in all events recognizing any transfers made in accordance with the terms of this Warrant. (b) This Warrant and the rights granted hereunder shall be assignable in compliance with all federal securities and blue sky laws by the holder hereof without the consent of the Company. (c) The Company is obligated to register the Warrant Shares for resale under the Securities Act pursuant to the Registration Rights Agreement dated September 22, 1999 by and between the Company and the Buyer listed on the signature page thereto (the "Registration Rights Agreement") and the initial holder of this Warrant (and certain assignees thereof) is entitled to the registration rights in respect of the Warrant Shares as set forth in the Registration Rights Agreement. Section 8. Adjustment of Warrant Exercise Price and Number of Shares. The --------------------------------------------------------- Warrant Exercise Price and the number of shares of Common Stock issuable upon exercise of this Warrant shall be adjusted from time to time as follows: (a) Adjustment of Warrant Exercise Price and Number of Shares upon -------------------------------------------------------------- Issuance of Common Stock. If and whenever on or after the date of issuance of - ------------------------ this Warrant, the Company issues or sells, or is deemed to have issued or sold, any shares of Common Stock (other than shares of Common Stock deemed to have been issued by the Company in connection with an Approved Stock Plan or upon exercise or conversion of the Other Securities) for a consideration per share less than a price (the "Applicable Price") equal to the Warrant Exercise Price in effect immediately prior to such issuance or sale, then immediately after such issue or sale the Warrant Exercise Price then in effect shall be reduced to an amount equal to such consideration per share. Upon each such adjustment of the Warrant Exercise Price hereunder, the number of shares of Common Stock acquirable upon exercise of this Warrant shall be adjusted to the number of shares determined by multiplying the Warrant Exercise Price in effect immediately prior to such adjustment by the number of shares of Common Stock acquirable upon exercise of this Warrant immediately prior to such adjustment and dividing the product thereof by the Warrant Exercise Price resulting from such adjustment. (b) Effect on Warrant Exercise Price of Certain Events. For purposes -------------------------------------------------- of determining the adjusted Warrant Exercise Price under Section 8(a) above, the following shall be applicable: (i) Issuance of Options. If the Company in any manner grants any ------------------- Options and the lowest price per share for which one share of Common Stock is issuable upon the exercise of any such Option or upon conversion or exchange of any Convertible Securities issuable upon exercise of any such Option is less than the Applicable Price, then such share of Common -10- Stock shall be deemed to be outstanding and to have been issued and sold by the Company at the time of the granting or sale of such Option for such price per share. For purposes of this Section 8(b)(i), the Alowest price per share for which one share of Common Stock is issuable upon exercise of such Options or upon conversion or exchange of such Convertible Securities shall be equal to the sum of the lowest amounts of consideration (if any) received or receivable by the Company with respect to any one share of Common Stock upon the granting or sale of the Option, upon exercise of the Option and upon conversion or exchange of any Convertible Security issuable upon exercise of such Option. No further adjustment of the Warrant Exercise Price shall be made upon the actual issuance of such Common Stock or of such Convertible Securities upon the exercise of such Options or upon the actual issuance of such Common Stock upon conversion or exchange of such Convertible Securities. Notwithstanding the foregoing, no adjustment shall be made pursuant to this Section 8(b)(i) to the extent that such adjustment is based solely on the fact that the Convertible Securities issuable upon exercise of such Option are convertible into or exchangeable for Common Stock at a price which varies with the market price of the Common Stock. (ii) Issuance of Convertible Securities. If the Company in any ---------------------------------- manner issues or sells any Convertible Securities and the lowest price per share for which one share of Common Stock is issuable upon such conversion or exchange thereof is less than the Applicable Price, then such share of Common Stock shall be deemed to be outstanding and to have been issued and sold by the Company at the time of the issuance or sale of such Convertible Securities for such price per share. For the purposes of this Section 8(b)(ii), the Alowest price per share for which one share of Common Stock is issuable upon such conversion or exchange@ shall be equal to the sum of the lowest amounts of consideration (if any) received or receivable by the Company with respect to one share of Common Stock upon the issuance or sale of the Convertible Security and upon conversion or exchange of such Convertible Security. No further adjustment of the Warrant Exercise Price shall be made upon the actual issuance of such Common Stock upon conversion or exchange of such Convertible Securities, and if any such issue or sale of such Convertible Securities is made upon exercise of any Options for which adjustment of the Warrant Exercise Price had been or are to be made pursuant to other provisions of this Section 8(b), no further adjustment of the Warrant Exercise Price shall be made by reason of such issue or sale. Notwithstanding the foregoing, no adjustment shall be made pursuant to this Section 8(b)(ii) to the extent that such adjustment is based solely on the fact that such Convertible Securities are convertible into or exchangeable for Common Stock at a price which varies with the market price of the Common Stock. (iii) Change in Option Price or Rate of Conversion. If the -------------------------------------------- purchase price provided for in any Options, the additional consideration, if any, payable upon the issue, conversion or exchange of any Convertible Securities, or the rate at which any Convertible Securities are convertible into or exchangeable for Common Stock changes at any time, the Warrant Exercise Price in effect at the time of such change shall be adjusted to the Warrant Exercise Price which would have been in effect at such time had such Options or Convertible Securities provided for such changed purchase price, additional consideration or changed conversion rate, as the case may be, at the time initially granted, issued or sold and the number -11- of shares of Common Stock acquirable hereunder shall be correspondingly readjusted. For purposes of this Section 8(b)(iii), if the terms of any Option or Convertible Security that was outstanding as of the date of issuance of this Warrant are changed in the manner described in the immediately preceding sentence, then such Option or Convertible Security and the Common Stock deemed issuable upon exercise, conversion or exchange thereof shall be deemed to have been issued as of the date of such change. No adjustment pursuant to this Section 8(b) shall be made if such adjustment would result in an increase of the Warrant Exercise Price then in effect. (c) Effect on Warrant Exercise Price of Certain Events. For purposes of determining the adjusted Warrant Exercise Price under Sections 8(a) and 8(b), the following shall be applicable: (i) Calculation of Consideration Received. In case any Option is issued in connection with the issue or sale of other securities of the Company, together comprising one integrated transaction in which no specific consideration is allocated to such Options by the parties thereto, the Options will be deemed to have been issued for a consideration of $.01. If any Common Stock, Options or Convertible Securities are issued or sold or deemed to have been issued or sold for cash, the consideration received therefor will be deemed to be the net amount of cash received by the Company therefor. If any Common Stock, Options or Convertible Securities are issued or sold for a consideration other than cash, the amount of such consideration received by the Company will be the fair value of such consideration, except where such consideration consists of securities, in which case the amount of consideration received by the Company will be the average of the Closing Bid Price of such securities for the ten (10) consecutive trading days immediately preceding the date of receipt. If any Common Stock, Options or Convertible Securities are issued to the owners of the non-surviving entity in connection with any merger in which the Company is the surviving entity, the amount of consideration therefor will be deemed to be the fair value of such portion of the net assets and business of the non- surviving entity as is attributable to such Common Stock, Options or Convertible Securities, as the case may be. The fair value of any consideration other than cash or securities will be determined by the Company and the holders of the Note Warrants representing a majority of the shares of Common Stock obtainable upon exercise of the Note Warrants then outstanding. If such parties are unable to reach agreement within ten (10) days after the occurrence of an event requiring valuation (the "VALUATION EVENT"), the fair value of such consideration will be determined in good faith by the Board of Directors of the Company within five Business Days after the tenth (10th) day following the Valuation Event. The determination pursuant to the immediately preceding sentence made in good faith by the Board of Directors of the Company shall be final and binding upon all parties. (ii) Integrated Transactions. In case any Option is issued in ----------------------- connection with the issue or sale of other securities of the Company, together comprising one integrated transaction in which no specific consideration is allocated to such Options by the parties thereto, the Options will be deemed to have been issued for a consideration of $.01. -12- (iii) 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, and the disposition of any shares so owned or held will be considered an issue or sale of Common Stock. (iv) Record Date. If the Company takes a record of the holders ----------- of Common Stock for the purpose of entitling them (1) to receive a dividend or other distribution payable in Common Stock, Options or in Convertible Securities or (2) to subscribe for or purchase Common Stock, Options or Convertible Securities, then such record date will be deemed to be the date of the issue 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. (d) Adjustment of Warrant Exercise Price upon Subdivision or -------------------------------------------------------- Combination of Common Stock. 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, any Warrant Exercise 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. If the Company at any time after the date of issuance of this Warrant combines (by combination, reverse stock split or otherwise) one or more classes of its outstanding shares of Common Stock into a smaller number of shares, any Warrant Exercise Price in effect immediately prior to such combination will be proportionately increased and the number of shares of Common Stock obtainable upon exercise of this Warrant will be proportionately decreased.
