         FOR VALUE RECEIVED, subject to the provisions hereinafter set forth,
the undersigned, Glowpoint, Inc., a Delaware corporation (together with its
successors and assigns, the "Issuer"), hereby certifies that
_______________________________ or its registered assigns is entitled to
subscribe for and purchase, during the Term (as hereinafter defined), up to
____________________________________ (_____________) shares (subject to
adjustment as hereinafter provided) of the duly authorized, validly issued,
fully paid and non-assessable Common Stock of the Issuer, at an exercise price
per share equal to the Warrant Price then in effect, subject, however, to the
provisions and upon the terms and conditions hereinafter set forth. Capitalized
terms used in this Warrant and not otherwise defined herein shall have the
respective meanings specified in Section 9 hereof.

         1. Term. The term of this Warrant shall commence on February 17, 2004
and shall expire at 5:00 p.m., eastern time, on August 17, 2009 (such period
being the "Term").

2. Method of Exercise; Payment; Issuance of New Warrant; Transfer and Exchange.

         (a) Time of Exercise. The purchase rights represented by this Warrant
may be exercised in whole or in part during the Term commencing on August 17,
2004 and expiring on August 17, 2009.

<PAGE>

         (b) Method of Exercise. The Holder hereof may exercise this Warrant, in
whole or in part, by the surrender of this Warrant (with the exercise form
attached hereto duly executed) at the principal office of the Issuer, and by the
payment to the Issuer of an amount of consideration therefor equal to the
Warrant Price in effect on the date of such exercise multiplied by the number of
shares of Warrant Stock with respect to which this Warrant is then being
exercised, payable at such Holder's election (i) by certified or official bank
check or by wire transfer to an account designated by the Issuer, (ii) by
"cashless exercise" in accordance with the provisions of subsection (c) of this
Section 2, but only when a registration statement under the Securities Act
providing for the resale of the Warrant Stock is not then in effect, or (iii) by
a combination of the foregoing methods of payment selected by the Holder of this
Warrant.

         (c) Cashless Exercise. Notwithstanding any provisions herein to the
contrary and commencing one (1) year following the Original Issue Date, if (i)
the Per Share Market Value of one share of Common Stock is greater than the
Warrant Price (at the date of calculation as set forth below) and (ii) a
registration statement under the Securities Act providing for the resale of the
Warrant Stock is not then in effect, in lieu of exercising this Warrant by
payment of cash, the Holder may exercise this Warrant by a cashless exercise and
shall receive the number of shares of Common Stock equal to an amount (as
determined below) by surrender of this Warrant at the principal office of the
Issuer together with the properly endorsed Notice of Exercise in which event the
Issuer shall issue to the Holder a number of shares of Common Stock computed
using the following formula:

        X = Y - (A)(Y)
                ------
                  B

Where   X =    the number of shares of Common Stock to be issued to the Holder.

        Y      = the number of shares of Common Stock purchasable
               upon exercise of all of the Warrant or, if only a
               portion of the Warrant is being exercised, the
               portion of the Warrant being exercised.

        A =    the Warrant Price.

        B =    the Per Share Market Value of one share of Common Stock.

         (d) Issuance of Stock Certificates. In the event of any exercise of the
rights represented by this Warrant in accordance with and subject to the terms
and conditions hereof, (i) certificates for the shares of Warrant Stock so
purchased shall be dated the date of such exercise and delivered to the Holder
hereof within a reasonable time, not exceeding three (3) Trading Days after such
exercise or, at the request of the Holder (provided that a registration
statement under the Securities Act providing for the resale of the Warrant Stock
is then in effect), issued and delivered to the Depository Trust Company ("DTC")
account on the Holder's behalf via the Deposit Withdrawal Agent Commission
System ("DWAC") within a reasonable time, not exceeding three (3) Trading Days
after such exercise, and the Holder hereof shall be deemed for all purposes to
be the holder of the shares of Warrant Stock so purchased as of the date of such
exercise and (ii) unless this Warrant has expired, a new Warrant representing
the number of shares of Warrant Stock, if any, with respect to which this
Warrant shall not then have been exercised (less any amount thereof which shall
have been canceled in payment or partial payment of the Warrant Price as
hereinabove provided) shall also be issued to the Holder hereof at the Issuer's
expense within such time.

                                      -2-

         (e) Transferability of Warrant. Subject to Section 2(f), this Warrant
may be transferred by a Holder without the consent of the Issuer. If transferred
pursuant to this paragraph and subject to the provisions of subsection (f) of
this Section 2, this Warrant may be transferred on the books of the Issuer by
the Holder hereof in person or by duly authorized attorney, upon surrender of
this Warrant at the principal office of the Issuer, properly endorsed (by the
Holder executing an assignment in the form attached hereto) and upon payment of
any necessary transfer tax or other governmental charge imposed upon such
transfer. This Warrant is exchangeable at the principal office of the Issuer for
Warrants to purchase the same aggregate number of shares of Warrant Stock, each
new Warrant to represent the right to purchase such number of shares of Warrant
Stock as the Holder hereof shall designate at the time of such exchange. All
Warrants issued on transfers or exchanges shall be dated the Original Issue Date
and shall be identical with this Warrant except as to the number of shares of
Warrant Stock issuable pursuant hereto.

         (f) Compliance with Securities Laws.

                  (i) The Holder of this Warrant, by acceptance hereof,
         acknowledges that this Warrant or the shares of Warrant Stock to be
         issued upon exercise hereof are being acquired solely for the Holder's
         own account and not as a nominee for any other party, and for
         investment, and that the Holder will not offer, sell or otherwise
         dispose of this Warrant or any shares of Warrant Stock to be issued
         upon exercise hereof except pursuant to an effective registration
         statement, or an exemption from registration, under the Securities Act
         and any applicable state securities laws.

                  (ii) Except as provided in paragraph (iii) below, this Warrant
         and all certificates representing shares of Warrant Stock issued upon
         exercise hereof shall be stamped or imprinted with a legend in
         substantially the following form:

                  THIS WARRANT AND THE SHARES OF COMMON STOCK ISSUABLE UPON
                  EXERCISE HEREOF HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
                  ACT OF 1933, AS AMENDED (THE "SECURITIES ACT") OR ANY STATE
                  SECURITIES LAWS AND MAY NOT BE SOLD, TRANSFERRED OR OTHERWISE
                  DISPOSED OF UNLESS REGISTERED UNDER THE SECURITIES ACT AND
                  UNDER APPLICABLE STATE SECURITIES LAWS OR GLOWPOINT, INC.
                  SHALL HAVE RECEIVED AN OPINION OF COUNSEL THAT REGISTRATION OF
                  SUCH SECURITIES UNDER THE SECURITIES ACT AND UNDER THE
                  PROVISIONS OF APPLICABLE STATE SECURITIES LAWS IS NOT
                  REQUIRED.

<PAGE>

                  (iii) The Issuer agrees to reissue this Warrant or
         certificates representing any of the Warrant Stock, without the legend
         set forth above if at such time, prior to making any transfer of any
         such securities, the Holder shall give written notice to the Issuer
         describing the manner and terms of such transfer and removal as the
         Issuer may reasonably request. Such proposed transfer and removal will
         not be effected until: (a) either (i) the Issuer has received an
         opinion of counsel reasonably satisfactory to the Issuer, to the effect
         that the registration of such securities under the Securities Act is
         not required in connection with such proposed transfer, (ii) a
         registration statement under the Securities Act covering such proposed
         disposition has been filed by the Issuer with the Securities and
         Exchange Commission and has become effective under the Securities Act,
         (iii) the Issuer has received other evidence reasonably satisfactory to
         the Issuer that such registration and qualification under the
         Securities Act and state securities laws are not required, or (iv) the
         Holder provides the Issuer with reasonable assurances that such
         security can be sold pursuant to Rule 144 under the Securities Act; and
         (b) either (i) the Issuer has received an opinion of counsel reasonably
         satisfactory to the Issuer, to the effect that registration or
         qualification under the securities or "blue sky" laws of any state is
         not required in connection with such proposed disposition, or (ii)
         compliance with applicable state securities or "blue sky" laws has been
         effected or a valid exemption exists with respect thereto. The Issuer
         will respond to any such notice from a holder within five (5) business
         days. In the case of any proposed transfer under this Section 2(f), the
         Issuer will use reasonable efforts to comply with any such applicable
         state securities or "blue sky" laws, but shall in no event be required,
         (x) to qualify to do business in any state where it is not then
         qualified, (y) to take any action that would subject it to tax or to
         the general service of process in any state where it is not then
         subject, or (z) to comply with state securities or "blue sky" laws of
         any state for which registration by coordination is unavailable to the
         Issuer. The restrictions on transfer contained in this Section 2(f)
         shall be in addition to, and not by way of limitation of, any other
         restrictions on transfer contained in any other section of this
         Warrant. Whenever a certificate representing the Warrant Stock is
         required to be issued to a the Holder without a legend, in lieu of
         delivering physical certificates representing the Warrant Stock,
         provided the Issuer's transfer agent is participating in the Depository
         Trust Company ("DTC") Fast Automated Securities Transfer program, the
         Issuer shall use its reasonable best efforts to cause its transfer
         agent to electronically transmit the Warrant Stock to the Holder by
         crediting the account of the Holder's Prime Broker with DTC through its
         Deposit Withdrawal Agent Commission ("DWAC") system (to the extent not
         inconsistent with any provisions of this Warrant or the Purchase
         Agreement).

         3. Stock Fully Paid; Reservation and Listing of Shares; Covenants.

         (a) Stock Fully Paid. The Issuer represents, warrants, covenants and
agrees that all shares of Warrant Stock which may be issued upon the exercise of
this Warrant or otherwise hereunder will, upon issuance, be duly authorized,
validly issued, fully paid and non-assessable and free from all taxes, liens and
charges created by or through the Issuer. The Issuer further covenants and
agrees that during the period within which this Warrant may be exercised, the
Issuer will at all times have authorized and reserved for the purpose of the
issue upon exercise of this Warrant a sufficient number of shares of Common
Stock to provide for the exercise of this Warrant.

         (b) Reservation. If any shares of Common Stock required to be reserved
for issuance upon exercise of this Warrant or as otherwise provided hereunder
require registration or qualification with any governmental authority under any
federal or state law before such shares may be so issued, the Issuer will in
good faith use its reasonable best efforts at its expense to cause such shares
to be duly registered or qualified. If the Issuer shall list any shares of
Common Stock on any securities exchange or market it will, at its expense, list
thereon, maintain and increase when necessary such listing, of, all shares of
Warrant Stock from time to time issued upon exercise of this Warrant or as
otherwise provided hereunder (provided that such Warrant Stock has been
registered pursuant to a registration statement under the Securities Act then in
effect), and, to the extent permissible under the applicable securities exchange
rules, all unissued shares of Warrant Stock which are at any time issuable
hereunder, so long as any shares of Common Stock shall be so listed. The Issuer
will also so list on each securities exchange or market, and will maintain such
listing of, any other securities which the Holder of this Warrant shall be
entitled to receive upon the exercise of this Warrant if at the time any
securities of the same class shall be listed on such securities exchange or
market by the Issuer.

         (c) Covenants. The Issuer shall not by any action including, without
limitation, amending the Certificate of Incorporation or the by-laws of the
Issuer, or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities or any other action, avoid or
seek to avoid the observance or performance of any of 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 actions as may be necessary or appropriate to
protect the rights of the Holder hereof against dilution (to the extent
specifically provided herein) or impairment. Without limiting the generality of
the foregoing, the Issuer will (i) not permit the par value, if any, of its
Common Stock to exceed the then effective Warrant Price, (ii) not amend or
modify any provision of the Certificate of Incorporation or by-laws of the
Issuer in any manner that would adversely affect the rights of the Holders of
the Warrants, (iii) take all such action as may be reasonably necessary in order
that the Issuer may validly and legally issue fully paid and nonassessable
shares of Common Stock, free and clear of any liens, claims, encumbrances and
restrictions (other than as provided herein) upon the exercise of this Warrant,
and (iv) use its reasonable best efforts to obtain all such authorizations,
exemptions or consents from any public regulatory body having jurisdiction
thereof as may be reasonably necessary to enable the Issuer to perform its
obligations under this Warrant.

<PAGE>

         (d) Loss, Theft, Destruction of Warrants. Upon receipt of evidence
satisfactory to the Issuer of the ownership of and the loss, theft, destruction
or mutilation of any Warrant and, in the case of any such loss, theft or
destruction, upon receipt of indemnity or security satisfactory to the Issuer
or, in the case of any such mutilation, upon surrender and cancellation of such
Warrant, the Issuer will make and deliver, in lieu of such lost, stolen,
destroyed or mutilated Warrant, a new Warrant of like tenor and representing the
right to purchase the same number of shares of Common Stock.

         4. Adjustment of Warrant Price and Warrant Share Number. The number of
shares of Common Stock for which this Warrant is exercisable, and the price at
which such shares may be purchased upon exercise of this Warrant, shall be
subject to adjustment from time to time as set forth in this Section 4. The
Issuer shall give the Holder notice of any event described below which requires
an adjustment pursuant to this Section 4 in accordance with Section 5.
Notwithstanding anything contained herein to the contrary, the Warrant Price
shall not be adjusted pursuant to Section 4(d), (e) and (f) hereof to a price
that is less than the Per Share Market Value on the Original Issue Date.

         (a) Recapitalization, Reorganization, Reclassification, Consolidation,
Merger or Sale.

                  (i) In case the Issuer after the Original Issue Date shall do
         any of the following (each, a "Triggering Event"): (a) consolidate with
         or merge into any other Person and the Issuer shall not be the
         continuing or surviving corporation of such consolidation or merger, or
         (b) permit any other Person to consolidate with or merge into the
         Issuer and the Issuer shall be the continuing or surviving Person but,
         in connection with such consolidation or merger, any Capital Stock of
         the Issuer shall be changed into or exchanged for Securities of any
         other Person or cash or any other property, or (c) transfer all or
         substantially all of its properties or assets to any other Person, or
         (d) effect a capital reorganization or reclassification of its Capital
         Stock, then, and in the case of each such Triggering Event, proper
         provision shall be made so that, upon the basis and the terms and in
         the manner provided in this Warrant, the Holder of this Warrant shall
         be entitled upon the exercise hereof at any time after the consummation
         of such Triggering Event, to the extent this Warrant is not exercised
         prior to such Triggering Event, to receive at the Warrant Price in
         effect at the time immediately prior to the consummation of such
         Triggering Event in lieu of the Common Stock issuable upon such
         exercise of this Warrant prior to such Triggering Event, the
         Securities, cash and property to which such Holder would have been
         entitled upon the consummation of such Triggering Event if such Holder
         had exercised the rights represented by this Warrant immediately prior
         thereto, subject to adjustments (subsequent to such corporate action)
         as nearly equivalent as possible to the adjustments provided for
         elsewhere in this Section 4.

<PAGE>

                  (ii) Notwithstanding anything contained in this Warrant to the
         contrary, a Triggering Event shall not be deemed to have occurred if,
         prior to the consummation thereof, each Person (other than the Issuer)
         which may be required to deliver any Securities, cash or property upon
         the exercise of this Warrant as provided herein shall assume, by
         written instrument delivered to, and reasonably satisfactory to, the
         Holder of this Warrant, (A) the obligations of the Issuer under this
         Warrant (and if the Issuer shall survive the consummation of such
         Triggering Event, such assumption shall be in addition to, and shall
         not release the Issuer from, any continuing obligations of the Issuer
         under this Warrant) and (B) the obligation to deliver to such Holder
         such Securities, cash or property as, in accordance with the foregoing
         provisions of this subsection (a), such Holder shall be entitled to
         receive, and such Person shall have similarly delivered to such Holder
         an opinion of counsel for such Person, which counsel shall be
         reasonably satisfactory to such Holder, or in the alternative, a
         written acknowledgement executed by the President or Chief Financial
         Officer of the Issuer, stating that this Warrant shall thereafter
         continue in full force and effect and the terms hereof (including,
         without limitation, all of the provisions of this subsection (a)) shall
         be applicable to the Securities, cash or property which such Person may
         be required to deliver upon any exercise of this Warrant or the
         exercise of any rights pursuant hereto.

                  (b) Stock Dividends, Subdivisions and Combinations. If at any
         time the Issuer shall:

                           (i) take a record of the holders of its Common Stock
         for the purpose of entitling them to receive a dividend payable in, or
         other distribution of, shares of Common Stock,

                           (ii) subdivide its outstanding shares of Common Stock
         into a larger number of shares of Common Stock, or

                                      -7-
<PAGE>

                           (iii) combine its outstanding shares of Common Stock
         into a smaller number of shares of Common Stock,

then (1) the number of shares of Common Stock for which this Warrant is
exercisable immediately after the occurrence of any such event shall be adjusted
to equal the number of shares of Common Stock which a record holder of the same
number of shares of Common Stock for which this Warrant is exercisable
immediately prior to the occurrence of such event would own or be entitled to
receive after the happening of such event, and (2) the Warrant Price then in
effect shall be adjusted to equal (A) the Warrant Price then in effect
multiplied by the number of shares of Common Stock for which this Warrant is
exercisable immediately prior to the adjustment divided by (B) the number of
shares of Common Stock for which this Warrant is exercisable immediately after
such adjustment.

         (c) Certain Other Distributions. If at any time the Issuer shall take a
record of the holders of its Common Stock for the purpose of entitling them to
receive any dividend or other distribution of:

                           (i) cash (other than a cash dividend payable out of
         earnings or earned surplus legally available for the payment of
         dividends under the laws of the jurisdiction of incorporation of the
         Issuer),

                           (ii) any evidences of its indebtedness, any shares of
         stock of any class or any other securities or property of any nature
         whatsoever (other than cash, Common Stock Equivalents or Additional
         Shares of Common Stock), or

                           (iii) any warrants or other rights to subscribe for
         or purchase any evidences of its indebtedness, any shares of stock of
         any class or any other securities or property of any nature whatsoever
         (other than cash, Common Stock Equivalents or Additional Shares of
         Common Stock),

then (1) the number of shares of Common Stock for which this Warrant is
exercisable shall be adjusted to equal the product of the number of shares of
Common Stock for which this Warrant is exercisable immediately prior to such
adjustment multiplied by a fraction (A) the numerator of which shall be the Per
Share Market Value of Common Stock at the date of taking such record and (B) the
denominator of which shall be such Per Share Market Value minus the amount
allocable to one share of Common Stock of any such cash so distributable and of
the fair value (as determined in good faith by the Board of Directors of the
Issuer) of any and all such evidences of indebtedness, shares of stock, other
securities or property or warrants or other subscription or purchase rights so
distributable, and (2) the Warrant Price then in effect shall be adjusted to
equal (A) the Warrant Price then in effect multiplied by the number of shares of
Common Stock for which this Warrant is exercisable immediately prior to the
adjustment divided by (B) the number of shares of Common Stock for which this
Warrant is exercisable immediately after such adjustment. A reclassification of
the Common Stock (other than a change in par value, or from par value to no par
value or from no par value to par value) into shares of Common Stock and shares
of any other class of stock shall be deemed a distribution by the Issuer to the
holders of its Common Stock of such shares of such other class of stock within
the meaning of this Section 4(c) and, if the outstanding shares of Common Stock
shall be changed into a larger or smaller number of shares of Common Stock as a
part of such reclassification, such change shall be deemed a subdivision or
combination, as the case may be, of the outstanding shares of Common Stock
within the meaning of Section 4(b).

         (d) Issuance of Additional Shares of Common Stock.

                  (i) Subject to the third sentence of the first paragraph of
Section 4 hereof, in the event the Issuer shall at any time issue any Additional
Shares of Common Stock (otherwise than as provided in the foregoing subsections
(b) through (c) of this Section 4), at a price per share less than the Warrant
Price then in effect or without consideration, then the Warrant Price upon each
such issuance shall be adjusted to that price determined by multiplying the
Warrant Price then in effect by a fraction:

                           (A) the numerator of which shall be equal to the sum
                  of (x) the number of shares of Outstanding Common Stock
                  immediately prior to the issuance of such Additional Shares of
                  Common Stock plus (y) the number of shares of Common Stock
                  which the aggregate consideration for the total number of such
                  Additional Shares of Common Stock so issued would purchase at
                  a price per share equal to the Warrant Price then in effect,
                  and

                                      -8-
<PAGE>

                           (B) the denominator of which shall be equal to the
                  number of shares of Outstanding Common Stock immediately after
                  the issuance of such Additional Shares of Common Stock.

                  (ii) The provisions of paragraph (i) of Section 4(d) shall not
apply to any issuance of Additional Shares of Common Stock for which an
adjustment is provided under Section 4(b) or 4(c). No adjustment of the number
of shares of Common Stock for which this Warrant shall be exercisable shall be
made under paragraph (i) of Section 4(d) upon the issuance of any Additional
Shares of Common Stock which are issued pursuant to the exercise of any Common
Stock Equivalents, if any such adjustment shall previously have been made upon
the issuance of such Common Stock Equivalents (or upon the issuance of any
warrant or other rights therefor) pursuant to Section 4(e) or Section 4(f).

         (e) Issuance of Warrants or Other Rights. If at any time the Issuer
shall take a record of the holders of its Common Stock for the purpose of
entitling them to receive a distribution of, or shall in any manner (whether
directly or by assumption in a merger in which the Issuer is the surviving
corporation) issue or sell, any Common Stock Equivalents (or issue any warrant
or other rights therefor), whether or not the rights to exchange or convert
thereunder are immediately exercisable, and the price per share for which Common
Stock is issuable upon the exercise of such Common Stock Equivalents (or any
warrant or other rights therefor) shall be less than the Warrant Price in effect
immediately prior to the time of such issue or sale, then the number of shares
for which this Warrant is exercisable and the Warrant Price then in effect shall
be adjusted as provided in Section 4(d) on the basis that the maximum number of
Additional Shares of Common Stock issuable pursuant to all such Common Stock
Equivalents (or upon the issuance of any warrant or other rights therefor) shall
be deemed to have been issued and outstanding and the Issuer shall have received
all of the consideration payable therefor, if any, as of the date of the actual
issuance of such warrants or other rights. No adjustments of the Warrant Price
then in effect or the number of Warrant Shares for which this Warrant is
exercisable shall be made upon the actual issue of such Common Stock or of such
Common Stock Equivalents upon exercise of such warrants or other rights or upon
the actual issue of such Common Stock upon such conversion or exchange of such
Common Stock Equivalents.

         (f) Issuance of Common Stock Equivalents. If at any time the Issuer
shall take a record of the holders of its Common Stock for the purpose of
entitling them to receive a distribution of, or shall in any manner (whether
directly or by assumption in a merger in which the Issuer is the surviving
corporation) issue or sell, any Common Stock Equivalents, whether or not the
rights to exchange or convert thereunder are immediately exercisable, and the
price per share for which Common Stock is issuable upon such conversion or
exchange shall be less than the Warrant Price in effect immediately prior to the
time of such issue or sale, then the number of shares of Common Stock for which
this Warrant is exercisable and the Warrant Price then in effect shall be
adjusted as provided in Section 4(d) on the basis that the maximum number of
Additional Shares of Common Stock necessary to effect the conversion or exchange
of all such Common Stock Equivalents shall be deemed to have been issued and
outstanding and the Issuer shall have received all of the consideration payable
therefor, if any, as of the date of actual issuance of such Common Stock
Equivalents. No further adjustment of the number of shares of Common Stock for
which this Warrant is exercisable and the Warrant Price then in effect shall be
made under this Section 4(f) upon the issuance of any Common Stock Equivalents
which are issued pursuant to the exercise of any warrants or other subscription
or purchase rights therefor, if any such adjustment shall previously have been
made upon the issuance of such warrants or other rights pursuant to Section
4(e). No further adjustments of the number of shares of Common Stock for which
this Warrant is exercisable and the Warrant Price then in effect shall be made
upon the actual issue of such Common Stock upon conversion or exchange of such
Common Stock Equivalents.

         (g) Superseding Adjustment. If, at any time after any adjustment of the
number of shares of Common Stock for which this Warrant is exercisable and the
Warrant Price then in effect shall have been made pursuant to Section 4(e) or
Section 4(f) as the result of any issuance of warrants, other rights or Common
Stock Equivalents, and (i) such warrants or other rights, or the right of
conversion or exchange in such other Common Stock Equivalents, shall expire, and
all or a portion of such warrants or other rights, or the right of conversion or
exchange with respect to all or a portion of such other Common Stock
Equivalents, as the case may be shall not have been exercised, or (ii) the
consideration per share for which shares of Common Stock are issuable pursuant
to such Common Stock Equivalents, shall be increased solely by virtue of
provisions therein contained for an automatic increase in such consideration per
share upon the occurrence of a specified date or event, then for each
outstanding Warrant such previous adjustment shall be rescinded and annulled and
the Additional Shares of Common Stock which were deemed to have been issued by
virtue of the computation made in connection with the adjustment so rescinded
and annulled shall no longer be deemed to have been issued by virtue of such
computation. Upon the occurrence of an event set forth in this Section 4(g)
above, there shall be a recomputation made of the effect of such Common Stock
Equivalents on the basis of: (i) treating the number of Additional Shares of
Common Stock or other property, if any, theretofore actually issued or issuable
pursuant to the previous exercise of any such warrants or other rights or any
such right of conversion or exchange, as having been issued on the date or dates
of any such exercise and for the consideration actually received and receivable
therefor, and (ii) treating any such Common Stock Equivalents which then remain
outstanding as having been granted or issued immediately after the time of such
increase of the consideration per share for which shares of Common Stock or
other property are issuable under such Common Stock Equivalents; whereupon a new
adjustment of the number of shares of Common Stock for which this Warrant is
exercisable and the Warrant Price then in effect shall be made, which new
adjustment shall supersede the previous adjustment so rescinded and annulled.

         (h) Purchase of Common Stock by the Issuer. If the Issuer at any time
while this Warrant is outstanding shall, directly or indirectly through a
Subsidiary or otherwise, purchase, redeem or otherwise acquire any shares of
Common Stock at a price per share greater than the Per Share Market Value, then
the Warrant Price upon each such purchase, redemption or acquisition shall be
adjusted to that price determined by multiplying such Warrant Price by a
fraction (i) the numerator of which shall be the number of shares of Outstanding
Common Stock immediately prior to such purchase, redemption or acquisition minus
the number of shares of Common Stock which the aggregate consideration for the
total number of such shares of Common Stock so purchased, redeemed or acquired
would purchase at the Per Share Market Value; and (ii) the denominator of which
shall be the number of shares of Outstanding Common Stock immediately after such
purchase, redemption or acquisition. For the purposes of this subsection (h),
the date as of which the Per Share Market Price shall be computed shall be the
earlier of (x) the date on which the Issuer shall enter into a firm contract for
the purchase, redemption or acquisition of such Common Stock, or (y) the date of
actual purchase, redemption or acquisition of such Common Stock. For the
purposes of this subsection (h), a purchase, redemption or acquisition of a
Common Stock Equivalent shall be deemed to be a purchase of the underlying
Common Stock, and the computation herein required shall be made on the basis of
the full exercise, conversion or exchange of such Common Stock Equivalent on the
date as of which such computation is required hereby to be made, whether or not
such Common Stock Equivalent is actually exercisable, convertible or
exchangeable on such date.

         (i) Other Provisions applicable to Adjustments under this Section. The
following provisions shall be applicable to the making of adjustments of the
number of shares of Common Stock for which this Warrant is exercisable and the
Warrant Price then in effect provided for in this Section 4:

                  (i) Computation of Consideration. To the extent that any
Additional Shares of Common Stock or any Common Stock Equivalents (or any
warrants or other rights therefor) shall be issued for cash consideration, the
consideration received by the Issuer therefor shall be the amount of the cash
received by the Issuer therefor, or, if such Additional Shares of Common Stock
or Common Stock Equivalents are offered by the Issuer for subscription, the
subscription price, or, if such Additional Shares of Common Stock or Common
Stock Equivalents are sold to underwriters or dealers for public offering
without a subscription offering, the initial public offering price (in any such
case subtracting any amounts paid or receivable for accrued interest or accrued
dividends and without taking into account any compensation, discounts or
expenses paid or incurred by the Issuer for and in the underwriting of, or
otherwise in connection with, the issuance thereof). To the extent that such
issuance shall be for a consideration other than cash, then, except as herein
otherwise expressly provided, the amount of such consideration shall be deemed
to be the fair value of such consideration at the time of such issuance as
determined in good faith by the Board of Directors of the Issuer. In case any
Additional Shares of Common Stock or any Common Stock Equivalents (or any
warrants or other rights therefor) shall be issued in connection with any merger
in which the Issuer issues any securities, the amount of consideration therefor
shall be deemed to be the fair value, as determined in good faith by the Board
of Directors of the Issuer, of such portion of the assets and business of the
nonsurviving corporation as such Board in good faith shall determine to be
attributable to such Additional Shares of Common Stock, Common Stock
Equivalents, or any warrants or other rights therefor, as the case may be. The
consideration for any Additional Shares of Common Stock issuable pursuant to any
warrants or other rights to subscribe for or purchase the same shall be the
consideration received by the Issuer for issuing such warrants or other rights
plus the additional consideration payable to the Issuer upon exercise of such
warrants or other rights. The consideration for any Additional Shares of Common
Stock issuable pursuant to the terms of any Common Stock Equivalents shall be
the consideration received by the Issuer for issuing warrants or other rights to
subscribe for or purchase such Common Stock Equivalents, plus the consideration
paid or payable to the Issuer in respect of the subscription for or purchase of
such Common Stock Equivalents, plus the additional consideration, if any,
payable to the Issuer upon the exercise of the right of conversion or exchange
in such Common Stock Equivalents. In case of the issuance at any time of any
Additional Shares of Common Stock or Common Stock Equivalents in payment or
satisfaction of any dividends upon any class of stock other than Common Stock,
the Issuer shall be deemed to have received for such Additional Shares of Common
Stock or Common Stock Equivalents a consideration equal to the amount of such
dividend so paid or satisfied.

<PAGE>

                  (ii) When Adjustments to Be Made. The adjustments required by
this Section 4 shall be made whenever and as often as any specified event
requiring an adjustment shall occur, except that any adjustment of the number of
shares of Common Stock for which this Warrant is exercisable that would
otherwise be required may be postponed (except in the case of a subdivision or
combination of shares of the Common Stock, as provided for in Section 4(b)) up
to, but not beyond the date of exercise if such adjustment either by itself or
with other adjustments not previously made adds or subtracts less than one
percent (1%) of the shares of Common Stock for which this Warrant is exercisable
immediately prior to the making of such adjustment. Any adjustment representing
a change of less than such minimum amount (except as aforesaid) which is
postponed shall be carried forward and made as soon as such adjustment, together
with other adjustments required by this Section 4 and not previously made, would
result in a minimum adjustment or on the date of exercise. For the purpose of
any adjustment, any specified event shall be deemed to have occurred at the
close of business on the date of its occurrence.

                  (iii) Fractional Interests. In computing adjustments under
this Section 4, fractional interests in Common Stock shall be taken into account
to the nearest one one-hundredth (1/100th) of a share.

                  (iv) When Adjustment Not Required. If the Issuer shall take a
record of the holders of its Common Stock for the purpose of entitling them to
receive a dividend or distribution or subscription or purchase rights and shall,
thereafter and before the distribution to stockholders thereof, legally abandon
its plan to pay or deliver such dividend, distribution, subscription or purchase
rights, then thereafter no adjustment shall be required by reason of the taking
of such record and any such adjustment previously made in respect thereof shall
be rescinded and annulled.

         (j) Form of Warrant after Adjustments. The form of this Warrant need
not be changed because of any adjustments in the Warrant Price or the number and
kind of Securities purchasable upon the exercise of this Warrant.

         (k) Escrow of Warrant Stock. If after any property becomes
distributable pursuant to this Section 4 by reason of the taking of any record
of the holders of Common Stock, but prior to the occurrence of the event for
which such record is taken, and the Holder exercises this Warrant, any shares of
Common Stock issuable upon exercise by reason of such adjustment shall be deemed
the last shares of Common Stock for which this Warrant is exercised
(notwithstanding any other provision to the contrary herein) and such shares or
other property shall be held in escrow for the Holder by the Issuer to be issued
to the Holder upon and to the extent that the event actually takes place, upon
payment of the current Warrant Price. Notwithstanding any other provision to the
contrary herein, if the event for which such record was taken fails to occur or
is rescinded, then such escrowed shares shall be cancelled by the Issuer and
escrowed property returned.

                                      -12-
<PAGE>

         5. Notice of Adjustments. Whenever the Warrant Price or Warrant Share
Number shall be adjusted pursuant to Section 4 hereof (for purposes of this
Section 5, each an "adjustment"), the Issuer shall cause its Chief Financial
Officer to prepare and execute a certificate setting forth, in reasonable
detail, the event requiring the adjustment, the amount of the adjustment, the
method by which such adjustment was calculated (including a description of the
basis on which the Board made any determination hereunder), and the Warrant
Price and Warrant Share Number after giving effect to such adjustment, and shall
cause copies of such certificate to be delivered to the Holder of this Warrant
promptly after each adjustment. Absent manifest error, such certificate shall be
final and binding on the parties hereto.

         6. Fractional Shares. No fractional shares of Warrant Stock will be
issued in connection with any exercise hereof, but in lieu of such fractional
shares, the Issuer shall make a cash payment therefor equal in amount to the
product of the applicable fraction multiplied by the Per Share Market Value then
in effect.

         7. Ownership Cap and Certain Exercise Restrictions. (a) Notwithstanding
anything to the contrary set forth in this Warrant, at no time may a Holder of
this Warrant exercise this Warrant if the number of shares of Common Stock to be
issued pursuant to such exercise would exceed, when aggregated with all other
shares of Common Stock owned by such Holder at such time, the number of shares
of Common Stock which would result in such Holder owning more than 4.999% of all
of the Common Stock outstanding at such time; provided, however, that upon a
holder of this Warrant providing the Issuer with sixty-one (61) days notice
(pursuant to Section 13 hereof) (the "Waiver Notice") that such Holder would
like to waive this Section 7(a) with regard to any or all shares of Common Stock
issuable upon exercise of this Warrant, this Section 7(a) will be of no force or
effect with regard to all or a portion of the Warrant referenced in the Waiver
Notice; provided, further, that this provision shall be of no further force or
effect (i) during the sixty-one (61) days immediately preceding the expiration
of the term of this Warrant or (ii) upon the Holder's receipt of a Call Notice
(as defined in Section 8 hereof).

                  (b) The Holder may not exercise the Warrant hereunder to the
extent such exercise would result in the Holder beneficially owning (as
determined in accordance with Section 13(d) of the Exchange Act and the rules
thereunder) in excess of 9.999% of the then issued and outstanding shares of
Common Stock, including shares issuable upon exercise of the Warrant held by the
Holder after application of this Section; provided, however, that upon a holder
of this Warrant providing the Issuer with a Waiver Notice that such holder would
like to waive this Section 7(b) with regard to any or all shares of Common Stock
issuable upon exercise of this Warrant, this Section 7(b) shall be of no force
or effect with regard to those shares of Warrant Stock referenced in the Waiver
Notice; provided, further, that this provision shall be of no further force or
effect (i) during the sixty-one (61) days immediately preceding the expiration
of the term of this Warrant or (ii) upon the Holder's receipt of a Call Notice.

                                      -13-
<PAGE>

         8. Call. Notwithstanding anything herein to the contrary, the Issuer,
at its option, may call up to one hundred percent (100%) of this Warrant by
providing the Holder of this Warrant written notice pursuant to Section 13 (the
"Call Notice") if (a) the Issuer completes a bona fide underwritten public
offering during the Term resulting in gross proceeds to the Issuer of at least
$40,000,000 and, commencing six months and one day following the Original Issue
Date, the Per Share Market Value of the Common Stock is greater than $5.50 (as
may be adjusted for any stock splits or combinations of the Common Stock) for a
period of ten (10) consecutive Trading Days immediately prior to the date of
delivery of the Call Notice, or (b) commencing twelve (12) months following the
Original Issue Date, the Per Share Market Value of the Common Stock is greater
than $7.50 (as may be adjusted for any stock splits or combinations of the
Common Stock) for a period of ten (10) consecutive Trading Days immediately
prior to the date of delivery of the Call Notice; provided, that (i) a
registration statement under the Securities Act providing for the resale of the
Warrant Stock and the Common Stock issued pursuant to the Purchase Agreement is
then in effect and has been effective, without lapse or suspension of any kind,
for a period of 60 consecutive calendar days, (ii) trading in the Common Stock
shall not have been suspended by the Securities and Exchange Commission or
Nasdaq and (iii) the Issuer is in material compliance with the terms and
conditions of this Warrant and the other Transaction Documents (as defined in
the Purchase Agreement); provided, further, that a registration statement under
the Securities Act providing for the resale of the Warrant Stock and the Common
Stock issued pursuant to the Purchase Agreement is in effect from the date of
delivery of the Call Notice until the date which is the later of (A) the date
the Holder exercises the Warrant pursuant to the Call Notice and (B) the 10th
Trading Day after the Holder receives the Call Notice (the "Early Termination
Date"). The rights and privileges granted pursuant to this Warrant with respect
to the shares of Warrant Stock subject to the Call Notice (the "Called Warrant
Shares") shall expire on the Early Termination Date if this Warrant is not
exercised with respect to such Called Warrant Shares prior to such Early
Termination Date. In the event this Warrant is not exercised with respect to the
Called Warrant Shares, the Issuer shall remit to the Holder of this Warrant (1)
$.10 per Called Warrant Share and (2) a new Warrant representing the number of
shares of Warrant Stock, if any, which shall not have been subject to the Call
Notice upon the Holder tendering to the Issuer the applicable Warrant
certificate.

then, in each of such cases, the Issuer shall give written notice to the Holder
of the date on which (i) the books of the Issuer shall close or a record shall
be taken for such dividend, distribution or subscription rights or (ii) such
reorganization, reclassification, consolidation, merger, disposition,
dissolution, liquidation or winding-up, as the case may be, shall take place.
Such notice also shall specify the date as of which the holders of Common Stock
of record shall participate in such dividend, distribution or subscription
rights, or shall be entitled to exchange their certificates for Common Stock for
securities or other property deliverable upon such reorganization,
reclassification, consolidation, merger, disposition, dissolution, liquidation
or winding-up, as the case may be. Such notice shall be given at least twenty

in respect thereto. Except as otherwise specifically provided herein, no holder,
as such, of this Warrant shall be entitled to vote or receive dividends or be

such, any of the rights of a stockholder of the Issuer 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 Issuer,
whether such liabilities are asserted by the Issuer or by creditors of the
Issuer. Notwithstanding this Section 10, the Issuer will provide the holder of
this Warrant with copies of the same notices and other information given to the
stockholders of the Issuer generally, contemporaneously with the giving thereof
to the stockholders. This Warrant entitles the Holder to receive copies of all
financial and other information distributed or required to be distributed to the
holders of the Common Stock.

         11. Amendment and Waiver. Any term, covenant, agreement or condition in
this Warrant may be amended, or compliance therewith may be waived (either
generally or in a particular instance and either retroactively or
prospectively), by a written instrument or written instruments executed by the
Issuer and the Majority Holders; provided, however, that no such amendment or
waiver shall reduce the Warrant Share Number, increase the Warrant Price,
shorten the period during which this Warrant may be exercised or modify any
provision of this Section 10 without the consent of the Holder of this Warrant.

         12. Governing Law. THIS WARRANT SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT GIVING EFFECT TO
PRINCIPLES OF CONFLICTS OF LAW.
