      Section 2. 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 exercise
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) 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, unless the holder elects to make a "Cashless
Exercise" under certain conditions in accordance with section 2(d) of this
Agreement, 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 third
Business Day following the date of receipt of the Exercise Notice, the Aggregate
Exercise Price 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, then the Company shall, on or before the third 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, 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) above or notification to the Company of a Cashless
Exercise referred to in Section 2(d), 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.

            (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 (5) Business Days after any exercise and at its
own expense, issue a new Warrant identical in all respects to this Warrant
exercised except it shall represent rights to purchase the number of Warrant
Shares purchasable immediately prior to such exercise under this 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.

                                        3
<PAGE>

            (d) Notwithstanding anything contained herein to the contrary, the
holder of this Warrant may elect to 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, receive
upon such exercise the "Net Number" of shares of Common Stock (a "Cashless
Exercise") which shall be determined according to the following formula:

      Net Number = (A x B) - (A x C)
                    ---------------
                           B

            For purposes of the foregoing formula:

                  A=the total number of Warrant 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 exercise 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 have been duly and validly authorized and
when issued and delivered upon exercise of this Warrant will be validly issued,
fully paid and nonassessable and free from all taxes, liens and charges with
respect to the issue thereof.

            (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 the number of shares of Common Stock needed to provide for the exercise
of the rights then represented by this Warrant.

            (d) The shares of Common Stock issuable upon exercise of this
Warrant shall be listed 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.

                                       4
<PAGE>

            (e) The Company will not, by amendment of its Certificate of
Incorporation or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issuance 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
consistent with the tenor and purpose 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; 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 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 by virtue of this Warrant 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.

      Section 6. Securities Laws.

            (a) Shares may not be issued to the Holder upon exercise of this
Warrant if, at the time of exercise, a registration statement with respect to
such shares is not effective under the Securities Act or if such shares are not
qualified or exempt from qualification in the state wherein the holder of this
Warrant resides.

            (b) If at any time prior to the Expiration Date the Company proposes
to file a registration statement under the Securities Act with respect to an
underwritten offering of Common Stock (except on Form S-4 or Form S-8 or any
successor forms thereto), for its own account, then the Company shall give
written notice of such proposed filing to the holder of this Warrant or of the
Warrant Shares at least 15 days in advance of the anticipated filing date (the
"Piggyback Notice"). The Piggyback Notice shall offer such holders the
opportunity to register such amount of Warrant Shares as each such holder may
request (a "Piggyback Registration");

                                       5
<PAGE>

subject in all events to the agreement of the underwriter or underwriters of the
offering contemplated by such registration statement that such Warrant Shares
can be included in such registration statement without adversely affecting such
offering. Any reduction in the number of securities to be so offered shall be
(i) first, pro-rata among all security holders who are exercising "piggyback"
registration rights, based on the number of registrable securities originally
proposed to be sold by each of them, and (ii) second, pro-rata among all
security holders who are exercising "demand" registration rights pursuant to a
registration rights agreement with the Company, based on the number of
registrable securities originally proposed to be sold by each of them.

      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 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.

            (b) This Warrant and the rights granted hereunder shall be
assignable by the holder hereof without the consent of the Company.

      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 upon Sale or Issuance of
Securities. If the Company shall (A) sell or issue shares of its Common Stock,
(B) issue rights, options or warrants to subscribe for or purchase shares of
Common Stock or (C) issue or sell other rights for shares of Common Stock or
securities convertible or exchangeable into shares of Common Stock (such
securities and the Common Stock collectively, the "Securities"), at a Price Per
Share (as defined below) less than the Warrant Exercise Price in effect on the
date that the Company fixes the offering price of such Securities, then in each
such case the Warrant Exercise Price in effect immediately prior to the issuance
of such Securities shall be adjusted so that it shall equal the Price Per Share
for such Securities. The adjustment provided for in this Section 8(a) shall
become effective immediately after such issuance and shall be made successively
whenever any such Securities are issued; provided that no further adjustments in
the Warrant Exercise Price shall be made upon the subsequent exercise,
conversion or exchange, as applicable, of such Securities pursuant to the
original terms of such Securities. In determining the "Price Per Share" under
this Section 8(a), there shall be taken into account any consideration received
by the Company for such Securities and any consideration required to be paid
upon the exercise, conversion or exchange, as applicable, of such Securities.
The value of all such consideration (if other than cash) shall be determined by
the Company's Board of Directors, whose determination shall be conclusive if
made in good faith. If all of such Securities are not so issued or expire or
terminate without having been exercised, converted or exchanged, the Warrant
Exercise Price then in effect shall be appropriately readjusted to the Warrant
Exercise Price that would then be in effect had the adjustments made upon the
issuance of such Securities not been made.

                                       6
<PAGE>

Notwithstanding the foregoing, the provisions of this Section 8(a) shall not
apply to the issuance of Common Stock to directors, officers or employees of, or
consultants to, the Company or its subsidiaries upon the exercise of options
pursuant to a stock grant, option plan, purchase plan or other employee stock
incentive program or other arrangement approved by the Board of Directors of the
Company.

            (b) 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, the 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, the 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. Any adjustment under this Section 8(b) shall become effective at the
close of business on the date the subdivision or combination becomes effective.

            (c) Reclassification or Merger. In case of any reclassification or
other change of securities of the class issuable upon exercise of this Warrant
(other than a change solely in par value or from par value to no par value or
vice versa or as a result of a subdivision or combination of Shares or other
securities subject to this Warrant), the Company shall duly execute and deliver
to the holder of this Warrant a new Warrant as nearly equivalent as possible to
this Warrant; and in case of any merger of the Company with or into another
corporation (other than a merger with another corporation in which the Company
is the surviving corporation and which does not result in any reclassification
or change of outstanding securities issuable upon exercise of this Warrant), or
in case of any sale of all or substantially all of the assets of the Company,
the Company, or such successor or purchasing entity shall (i) duly execute and
deliver to the holder a new Warrant as nearly equivalent as possible to this
Warrant or (ii) make appropriate written provisions, without the issuance of a
new Warrant, so that the holder shall have the right to receive upon exercise of
this Warrant, at a total exercise price not to exceed that payable upon the
exercise of the unexercised portion of this Warrant, and in lieu of the shares
of Common Stock or other securities theretofore issuable upon exercise of this
Warrant, the kind and amount of shares of stock, other securities, money and
property receivable upon such reclassification, change, merger or sale by a
holder of the number of shares of Common Stock or other securities then
unexercised and purchasable under this Warrant. Any new Warrant shall provide
for adjustments that shall be as nearly equivalent as may be practicable to the
adjustments provided for in this Section 8. The provisions of this Section 8(c)
shall similarly apply to successive recapitalizations, reclassifications,
reorganizations, changes, mergers and sales.

            (d) Minimum Adjustment of Warrant Exercise Price. No adjustment of
the Warrant Exercise Price shall be made under this Section 8 in an amount of
less than 1% of the Warrant Exercise Price in effect at the time such adjustment
is otherwise required to be made, but any such lesser adjustment shall be
carried forward and shall be made at the time and together with the next

                                       7
<PAGE>

subsequent adjustment which, together with any adjustments so carried forward,
shall amount to not less than 1% of such Warrant Exercise Price. No adjustments
shall be made pursuant to this Section 8 which would result in an increase in
the Warrant Exercise Price.

            (e) Notices.

            (i) Immediately upon any adjustment of a Warrant Exercise Price, the
      Company will give written notice thereof to the holder of this Warrant,
      setting forth in reasonable detail, and certifying, the calculation of
      such adjustment.

            (ii) The Company will give written notice to the holder of this
      Warrant at least ten (10) days prior to the date on which the Company
      closes its books or takes a record (A) with respect to any dividend or
      distribution upon the Common Stock, (B) with respect to any pro rata
      subscription offer to holders of Common Stock or (C) for determining
      rights to vote with respect to any Organic Change (as defined below),
      dissolution or liquidation, provided that such information shall be made
      known to the public prior to or in conjunction with such notice being
      provided to such holder. Any recapitalization, reorganization,
      reclassification, consolidation, merger, sale of all or substantially all
      of the Company's assets to another Person or other transaction in each
      case which is effected in such a way that holders of Common Stock are
      entitled to receive (either directly or upon subsequent liquidation)
      stock, securities or assets with respect to or in exchange for Common
      Stock is referred to herein as an "Organic Change."

            (iii) The Company will also give written notice to the holder of
      this Warrant at least ten (10) days prior to the date on which any Organic
      Change, dissolution or liquidation will take place, provided that such
      information shall be made known to the public prior to or in conjunction
      with such notice being provided to such holder.

      Section 9. Redemption.

            (a) Mandatory Redemption of Warrants. The holder of this Warrant
may, at any time and from time to time on or within sixty (60) days after the
closing of any transaction or series of transactions during any six month period
in which the Company shall have issued equity or debt securities having
aggregate gross proceeds to the Company of at least $5,000,000 or more after
the date of this Warrant, demand a determination of the Redemption Price (a
"Determination Notice") for purposes of this Section 9(b). Within 5 days after
the receipt of any Determination Notice from the holder, the Company shall give
to the holder notice of the Redemption Price, including a reasonably detailed
description of the method of calculation thereof, determined as of the day
preceding such notice of the Redemption Price. At any time within 30 days after
receipt of notice of the Redemption Price the holder may demand redemption of
this Warrant, in whole or in part, at the Redemption Price by notice to the
Company, which Redemption Price shall be payable on the third Business Day after
receipt of notice of such demand (any such date, the "Redemption Due Date") in
immediately available funds to the holder upon surrender of this Warrant to the
Company. Thereupon, the right to purchase shares of Common Stock theretofore
represented by this Warrant as to which the holder has demanded (and the Company
may effect) redemption shall terminate, and this Warrant shall

                                       8
<PAGE>

represent the right of the holder to receive the full Redemption Price from the
Company in accordance with this Section.

            (b) Any right to exercise a Warrant shall terminate at 5:00 P.M.
(New York time) on the business day immediately preceding the Redemption Date or
Redemption Due Date, as applicable. On and after the Redemption Date or
Redemption Due Date, as applicable, holders of the Warrants shall have no
further rights except to receive, upon surrender of the Warrant, the redemption
price.

            (c) From and after the Redemption Date specified, the Company shall,
at the place specified in the notice of redemption, upon presentation and
surrender to the Company by or on behalf of the registered holder thereof of one
or more warrant certificates evidencing Warrants to be redeemed (or an affidavit
of loss for such Warrant, which shall include provisions indemnifying the
Company with respect to such loss, and otherwise in a form reasonably acceptable
to the Company), deliver or cause to be delivered to or upon the written order
of such holder a sum in cash equal to the redemption price of each such Warrant.
From and after the Redemption Date and upon the deposit or setting aside by the
Company of a sum sufficient to redeem all the Warrants called for redemption,
such Warrants shall expire and become void and all rights hereunder and under
the warrant certificates, except the right to receive payment of the redemption
price, shall cease.

      Section 10. Lost, Stolen, Mutilated or Destroyed Warrant. If this Warrant
is lost, stolen, mutilated or destroyed, the Company shall, on receipt of an
indemnification undertaking (or, in the case of a mutilated Warrant, the
Warrant), issue a new Warrant of like denomination and tenor as this Warrant so
lost, stolen, mutilated or destroyed.

      Section 11. Notice. Any notices, consents, waivers or other communications
required or permitted to be given under the terms of this Warrant must be in
writing and will be deemed to have been delivered: (i) upon receipt, when
delivered personally; (ii) upon receipt, when sent by facsimile (provided
confirmation of transmission is mechanically or electronically generated and
kept on file by the sending party); or (iii) one Business Day after deposit with
a nationally recognized overnight delivery service, in each case properly
addressed to the party to receive the same. The addresses and facsimile numbers
for such communications shall be:
