2.       EXERCISE OF WARRANT.

                  2.1      METHOD OF EXERCISE.

as to a fractional share of Common Stock), at any time and from time to time
during the Exercise Period by the Holder hereof by delivery of a notice of
exercise (a "NOTICE OF EXERCISE") substantially in the form attached hereto as
Exhibit A via facsimile to the Company. Promptly thereafter the Holder shall
surrender this Warrant to the Company at its principal office, accompanied by

for which this Warrant is being exercised (the "EXERCISE PRICE"). Payment of the
Exercise Price shall be made, at the option of the Holder, (i) by check or bank
draft payable to the order of the Company, or (ii) by wire transfer to the
account of the Company.

                  (b) In addition to the foregoing, at the option of Holder,
this Warrant may be exercised, at any time or from time to time, in the
following "cashless exercise" transactions:

                           (i) Upon written notice of exercise from the Holder
                  to the Company that the Holder is exercising this Warrant in
                  whole or in part and as consideration of such exercise is
                  authorizing the Company to withhold from issuance a number of
                  shares of Common Stock issuable upon exercise of this Warrant,
                  the Company shall deliver to the Holder (without payment by
                  the Holder of the aggregate Purchase Price) that number of
                  shares of Common Stock equal to the quotient obtained by
                  dividing (x) the Spread Value by (y) the Fair Market Value of
                  one share of Common Stock immediately prior to the exercise of
                  the Conversion Right. The shares withheld by the Company shall
                  no longer be issuable under this Warrant.

                           (ii) Fair Market Value of a share of Warrant Shares
                  as of a particular date (the "Determination Date") shall mean:

                                    (A) If the Warrant Shares are traded on an
                           exchange or are quoted on the Nasdaq National Market
                           or the Nasdaq SmallCap Market ("Nasdaq"), then the
                           average of the closing or last sale price,
                           respectively, reported for the five trading days
                           immediately preceding the Determination Date.

                                    (B) If the Warrant Shares are not traded on
                           an exchange or on Nasdaq but are traded in the
                           over-the-counter market or other similar organization
                           (including the OTC Bulletin Board), then the average
                           of the closing bid and ask prices reported for the
                           five trading days immediately preceding the
                           Determination Date.

                                    (C) If the Warrant Shares are not traded as
                           provided above, then the price determined in good
                           faith by the Board of Directors of the Company,
                           provided that (i) the basis or bases of each such
                           determination shall be set forth in the corporate
                           records of the Company pertaining to meetings and
                           other actions of such board, and (ii) such records
                           are available to the Holder for inspection during
                           normal business hours of the Company upon the giving
                           of reasonable prior notice.

                                    (D) If the Determination Date is the date of
                           a liquidation, dissolution or winding up, or any
                           event deemed to be a liquidation, dissolution or
                           winding up pursuant to the Company's certificate of
                           incorporation, then all amounts to be payable per
                           share to Holders of the securities then comprising
                           Warrant Shares pursuant to the charter in the event
                           of such liquidation, dissolution or winding up, plus
                           all other amounts to be payable per share in respect
                           of the Warrant Shares in liquidation under the
                           certificate of incorporation, assuming for the
                           purposes of this clause (D) that all of the shares of
                           Warrant Shares then issuable upon exercise of all of
                           the Warrants are outstanding at the Determination
                           Date.

                           (iii) The term "Spread Value" shall mean (i) the
                  number of shares exercised at a given time multiplied by the
                  Fair Market Value of one share of Common Stock, less (ii)
                  aggregate applicable Exercise Price.

                  (c) Upon exercise, the Holder shall be entitled to receive,
promptly after payment in full, one or more certificates, issued in the Holder's
name or in such name or names as the Holder may direct, subject to the
limitations on transfer contained herein, for the number of shares of Common
Stock so purchased. The shares of Common Stock so purchased shall be deemed to
be issued as of the close of business on the date on which the Company shall
have received from the Holder payment in full of the Exercise Price (the
"EXERCISE DATE").

                  (d) Notwithstanding anything to the contrary set forth herein,
upon exercise of all or a portion of this Warrant in accordance with the terms
hereof, the Holder shall not be required to physically surrender this Warrant to
the Company. Rather, records showing the amount so exercised and the date of
exercise shall be maintained on a ledger substantially in the form of Annex B
attached hereto (a copy of which shall be delivered to the Company or transfer
agent with each Notice of Exercise). It is specifically contemplated that the
Company shall act as the calculation agent for all exercises of this Warrant. In
the event of any dispute or discrepancies, such records maintained by the
Holders shall be controlling and determinative in the absence of manifest error.
The Holder and any assignee, by acceptance of this Warrant, acknowledge and
agree that, by reason of the provisions of this paragraph, following an exercise
of a portion of this Warrant, the number of shares of Common Stock represented
by this Warrant will be the amount indicated on Annex B attached hereto (which
may be less than the amount stated on the face hereof)."

                  2.2 REGULATION D RESTRICTIONS. The Holder hereof represents
and warrants to the Company that it has acquired this Warrant and anticipates
acquiring the shares of Common Stock issuable upon exercise of the Warrant
solely for its own account for investment purposes and not with a view to or for
resale of such securities unless such resale has been registered with the
Commission or an applicable exemption is available therefore. At the time this
Warrant is exercised, the Company may require the Holder to state in the Notice
of Exercise such representations concerning the Holder as are necessary or
appropriate to assure compliance by the Holder with the Securities Act.

                  2.3 COMPANY ACKNOWLEDGMENT. The Company will, at the time of
the exercise of this Warrant, upon request of the Holder hereof, acknowledge in
writing its continuing obligation to afford to such Holder the registration
rights to which such Holder shall continue to be entitled after such exercise in
accordance with the provisions of a Registration Rights Agreement dated the date
hereof (the "Registration Rights Agreement"). If the Holder shall fail to make
any such request, such failure shall not affect the continuing obligation of the
Company to afford such Holder any such rights.

                  2.4 LIMITATION ON EXERCISE. Notwithstanding the rights of the
Holder to exercise all or a portion of this Warrant as described herein, such
exercise rights shall be limited, solely to the extent set forth in the Purchase
Agreement as if such provisions were specifically set forth herein. In addition,
the number of shares of Common Stock issuable upon exercise of this Warrant is
subject to reduction as specified in Section 10.3 of the Purchase Agreement.

         3. DELIVERY OF STOCK CERTIFICATES, ETC., ON EXERCISE. As soon as
practicable after the exercise of this Warrant, and in any event within five (5)
business days thereafter, the Company at its expense (including the payment by
it of any applicable issue, stamp or transfer taxes) will cause to be issued in
the name of and delivered to the Holder thereof, or, to the extent permissible
hereunder, to such other person as such Holder may direct, a certificate or
certificates for the number of fully paid and nonassessable shares of Common
Stock (or Other Securities) to which such Holder shall be entitled on such
exercise, plus, in lieu of any fractional share to which such Holder would
otherwise be entitled, cash equal to such fraction multiplied by the then

         4. NO IMPAIRMENT. The Company will not, by amendment of its Certificate
of Incorporation or through any reorganization, transfer of assets,

the terms of this Warrant, but will at all times in good faith assist in the
carrying out of all such terms and in the taking of all such action as may be
necessary or appropriate in order to protect the rights of the Holder of this
Warrant against impairment. Without limiting the generality of the foregoing,
the Company (a) will not increase the par value of any shares of stock

is to be taken for the purpose of such dividend, distribution or right, and
stating the amount and character of such dividend, distribution or right, and
(ii) the date on which any such reorganization, reclassification,
recapitalization, transfer, consolidation, merger, dissolution, liquidation or

shares of Common Stock (or Other Securities) for then and in each such event the

                  (a) On surrender for exchange of this Warrant, properly

will issue and deliver to or on the order of the Holder thereof a new Warrant of
