SECTION 2.  DURATION AND EXERCISE OF WARRANT

                  2.1      EXERCISE PERIOD

                  Subject to the provisions hereof, this Warrant may be
exercised at any time and from time to time during the period commencing on the
Initial Exercise Date and ending on the Expiration Date. After the Expiration
Date, this Warrant shall become void and all rights to purchase Warrant Shares
hereunder shall thereupon cease.

                  2.2      METHOD OF EXERCISE AND PAYMENT

                  (a)      METHOD OF EXERCISE. Subject to Section 2.1 hereof and
compliance with all applicable Federal and state securities laws, the purchase
right represented by this Warrant may be exercised, in whole or in part, by the
Warrant Holder by (i) surrender of this Warrant and delivery of an exercise form
specifying the number of shares to be purchased, duly executed, at the principal
office of the Company and (ii) payment to the Company of an amount equal to the
product of the then applicable Exercise Price multiplied by the number of
Warrant Shares then being purchased. At the election of the Warrant holder, the
purchase price may be paid by surrender of this Warrant for the full number of
shares for which this Warrant is then exercisable less that number of shares
having a fair market value equal to the aggregate exercise price. For purposes
of this Section, fair market value shall be determined as follows: if the Common
Shares are then traded on the over-the-counter market on the date in question,
the last reported per-share sales price; provided that if there have been no
sales reported in the most recent two trading days at the time of determination,
then the closing bid price (or average of bid prices) last quoted on such date
by an established quotation service for over-the-counter securities.

                  (b)      METHOD OF PAYMENT. Payment shall be made either by
check drawn on a United States bank and for United States funds made payable to
the Company, or by wire transfer of United States funds for the account of the
Company, or by the cashless exercise provided above.

                  (c)      DELIVERY OF CERTIFICATE. In the event of any exercise
of the purchase right represented by this Warrant, certificates for the Warrant
Shares so purchased shall be delivered to the Warrant Holder within thirty (30)
days of delivery of the Exercise Form and, unless this Warrant has been fully
exercised or has expired, a new warrant representing the portion of the Warrant
Shares with respect to which this Warrant shall not then have been exercised
shall also be issued to the Warrant Holder within such thirty (30) day period.

                  2.3      SECURITIES ACT COMPLIANCE/RESTRICTIONS UPON TRANSFER

                           Reference is made to Sections 2, 3 and 4 of the
Investor Rights Agreement which by this reference are incorporated herein.

                                       3



SECTION 3.        VALIDITY AND RESERVATION OF WARRANT SHARES

                  The Company represents and warrants that all Warrant Shares
issued upon exercise of this Warrant will be validly issued, fully paid,
nonassessable and not subject to preemptive or similar rights. The Company
agrees that, as long as this Warrant may be exercised, the Company will have
authorized and reserved for issuance upon exercise of this Warrant a sufficient
number of shares of Common Stock to provide for exercise in full of this
Warrant.

SECTION 4.        FRACTIONAL SHARES

                  No fractional Warrant Shares shall be issued upon the exercise
of this Warrant, and the number of Warrant shares to be issued shall be rounded
to the nearest whole number.

SECTION 5.        LIMITED RIGHTS OF WARRANT HOLDER

                  The Warrant Holder shall not, solely by virtue of being the
Warrant Holder of this Warrant, have any of the rights of a stockholder of the
Company, either at law or equity, until this Warrant shall have been exercised.

SECTION 6.        LOSS OF WARRANT

                  Upon receipt by the Company of satisfactory evidence of the
loss, theft, destruction or mutilation of this Warrant and either (in the case
of loss, theft or destruction) reasonable indemnification and a bond
satisfactory to the Company if requested by the Company or (in the case of
mutilation) the surrender of this Warrant for cancellation, the Company will
execute and deliver to the Warrant Holder, without charge, a new warrant of like
denomination.

SECTION 7.        CERTAIN ADJUSTMENTS OF EXERCISE PRICE

                  7.1      ADJUSTMENT OF EXERCISE PRICE

                  The number, class and Exercise Price of securities for which
this Warrant may be exercised are subject to adjustment from time to time upon
the happening of certain events as hereinafter provided:

                  (a)      RECAPITALIZATION. If the outstanding shares of the
Company's Common Stock are divided into a greater number of shares or the
Company issues a stock dividend on its outstanding Common Stock, the number of
shares of Common Stock purchasable upon the exercise of this Warrant shall be
proportionately increased and the Exercise Price shall be proportionately
reduced and, conversely, if the outstanding shares of Common Stock are combined
into a smaller number of shares of Common Stock, the number of shares of Common
Stock purchasable upon the exercise of this Warrant shall be proportionately
reduced and the Exercise Price shall be proportionately increased. The increases
and reductions provided for in this Section 7.1.(a) shall be made with the
intent and, as nearly as practicable, the effect that

                                       4



neither the percentage of the total equity of the Company obtainable on
exercise of this Warrant nor the price payable for such percentage shall be
affected by any event described in this Section 7.1 (a).

                  (b)      MERGER OR REORGANIZATION, ETC. In the event of any
change in the Common Stock through merger, consolidation, reclassification,
reorganization (such as, but not limited to, spin-offs of a business whereby,
for example, a Company asset is contributed to a subsidiary which is then
spun-off to the Company's shareholders), partial or complete liquidation or
other change in the capital structure of the Company (not including the issuance
of additional shares of capital stock other than by stock dividend or stock
split), then, as a condition of such change in the capital structure of the
Company, appropriate and adequate provision shall be made so that the Warrant
Holder of this Warrant will have the right thereafter to receive upon the
exercise of this Warrant the kind and amount of shares of stock or other
securities or property to which it would have been entitled if immediately prior
to such merger, consolidation, reclassification, reorganization,
recapitalization or other change in the capital structure, it had held the
number of shares of Common Stock then obtainable upon the exercise of this
Warrant. In any such case appropriate adjustment shall be made in the
application of the provisions set forth herein with respect to the rights and
interest thereafter of the Warrant Holder, to the end that the provisions set
forth herein shall thereafter be applicable, as nearly as reasonably may be, in
relation to any shares of stock or other property thereafter deliverable upon
the exercise of this Warrant.

                  (c)      Reference is made to Section 9 (c) (iii) (d) of the
Amendment to Articles. It is agreed that if pursuant to said section of the
Amendment to Articles, the Series B Conversion ratio is required to be adjusted,
this Warrant shall likewise be adjusted on a proportional and similar basis as
the Series B Preferred Stock is adjusted.

                  7.2      NOTICE OF ADJUSTMENT

                  Whenever an event occurs requiring any adjustment to be made
pursuant to Section 7.1(a), 7.1(b) or (c), the Company shall promptly file with
its Secretary or an Assistant Secretary at its principal office and with its
stock transfer agent, if any, a certificate of its chief executive officer
specifying such adjustment, setting forth in reasonable detail the acts
requiring such adjustment, and stating such other facts as shall be necessary to
show the manner and figures used to compute such adjustment. Such chief
executive officer's certificate shall be made available at all reasonable times
for inspection by the Warrant Holder. Promptly (but in no event more than 30
days) after each such adjustment, the Company shall give a copy of such
certificate by certified mail to the Warrant Holder.

                                       5



SECTION 8.        SUBDIVISION OF WARRANT

                  At the request of the Warrant Holder in connection with a
transfer of a portion of this Warrant upon surrender of this Warrant for such
purpose to the Company at its principal office, the Company at its expense
(except for any transfer tax payable) will issue and exchange therefor new
Warrants of like tenor and date representing in the aggregate the amount of the
Warrant Shares.

SECTION 9.        REGISTRATION RIGHTS

                  The Initial Warrant Holder shall have all the registration
rights provided in that certain Investor Rights Agreement entered into
concurrently herewith pursuant to the Series B Stock and Warrant Purchase
Agreement, including the right to transfer such rights to a subsequent Holder
subject to the terms and conditions set forth in the Investor Rights Agreement..

SECTION 10.       REPRESENTATIONS AND WARRANTIES

                  10.1     BY WARRANT HOLDER

                  The Warrant Holder represents and warrants to the Company as
follows:

                  (a)      This Warrant and the Warrant Shares issuable upon
exercise thereof are being acquired for the Warrant Holder's own account, for
investment and not with a view to, or for resale in connection with, any
distribution or public offering thereof within the meaning of the Securities
Act. Upon exercise of this Warrant, the Warrant Holder shall, if so requested by
the Company, confirm in writing, in a form satisfactory to the Company, that the
securities issuable upon exercise of this Warrant are being acquired for
investment and not with a view toward distribution or resale.

                  (b)      The Warrant Holder understands that the Warrant and
the Warrant Shares have not been registered under the Securities Act by reason
of their issuance in a transaction exempt from the registration and prospectus
delivery requirements of the Act pursuant to Section 4(2) or Section 4(6)
thereof, and that they must be held by the Warrant Holder indefinitely, and that
the Warrant Holder must therefore bear the economic risk of such investment
indefinitely, unless a subsequent disposition thereof is registered under the
Securities Act or is exempted from such registration.

                  (c)      The Warrant Holder has such knowledge and experience
in financial and business matters that the Warrant Holder is capable of
evaluating the merits and risks of the purchase of this Warrant and the Warrant
Shares purchasable pursuant to the terms of this Warrant and of protecting the
Warrant Holder's interests in connection therewith. The Warrant Holder is an
accredited investor, as such term is defined in Rule 501 of Regulation D
promulgated pursuant to the 1984 Act.

                                       6



                  (d)      The Warrant Holder is able to bear the economic risk
of the purchase of the Warrant Shares pursuant to the terms of this Warrant.
