Date of Issuance: June 8, 2006


      FOR VALUE RECEIVED, the undersigned, StatSure Diagnostic Systems, 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 May 31, 2006 and shall
expire at 6:00 p.m., Eastern Time, on May 27, 2011 (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 beginning on November 27, 2006.

      (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.

<PAGE>

      (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 by the date such registration statement is
required to be effective pursuant to the Registration Rights Agreement (as
defined in the Purchase Agreement) or not effective at any time during the
Effectiveness Period (as defined in the Registration Rights Agreement) in
accordance with the terms of the Registration Rights Agreement, unless the
registration statement is not effective as a result of the Issuer exercising its
rights under Section 3(i) of the Registration Rights Agreement, 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 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 (the "Delivery
Date") 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. Notwithstanding the foregoing to the contrary, the
Issuer or its transfer agent shall only be obligated to issue and deliver the
shares to the DTC on a holder's behalf via DWAC if such exercise is in
connection with a sale and the Issuer and its transfer agent are participating
in DTC through the DWAC system.

<PAGE>

      (e) Compensation for Buy-In on Failure to Timely Deliver Certificates Upon
Exercise. In addition to any other rights available to the Holder, if the Issuer
fails to cause its transfer agent to transmit to the Holder a certificate or
certificates representing the Warrant Stock pursuant to an exercise on or before
the Delivery Date, and if after such date the Holder is required by its broker
to purchase (in an open market transaction or otherwise) shares of Common Stock
to deliver in satisfaction of a sale by the Holder of the Warrant Stock which
the Holder anticipated receiving upon such exercise (a "Buy-In"), then the
Issuer shall (1) pay in cash to the Holder the amount by which (x) the Holder's
total purchase price (including brokerage commissions, if any) for the shares of
Common Stock so purchased exceeds (y) the amount obtained by multiplying (A) the
number of shares of Warrant Stock that the Issuer was required to deliver to the
Holder in connection with the exercise at issue times (B) the price at which the
sell order giving rise to such purchase obligation was executed, and (2) at the
option of the Holder, either reinstate the portion of the Warrant and equivalent
number of shares of Warrant Stock for which such exercise was not honored or
deliver to the Holder the number of shares of Common Stock that would have been
issued had the Issuer timely complied with its exercise and delivery obligations
hereunder. For example, if the Holder purchases Common Stock having a total
purchase price of $11,000 to cover a Buy-In with respect to an attempted
exercise of shares of Common Stock with an aggregate sale price giving rise to
such purchase obligation of $10,000, under clause (1) of the immediately
preceding sentence the Issuer shall be required to pay the Holder $1,000. The
Holder shall provide the Issuer written notice indicating the amounts payable to
the Holder in respect of the Buy-In, together with applicable confirmations and
other evidence reasonably requested by the Issuer. Nothing herein shall limit a
Holder's right to pursue any other remedies available to it hereunder, at law or
in equity including, without limitation, a decree of specific performance and/or
injunctive relief with respect to the Issuer's failure to timely deliver
certificates representing shares of Common Stock upon exercise of this Warrant
as required pursuant to the terms hereof.

      (f) Transferability of Warrant. Subject to Section 2(h) hereof, this
Warrant may be transferred by a Holder without the consent of the Issuer. If
transferred pursuant to this paragraph, 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 thereto.

<PAGE>

      (g) Continuing Rights of Holder. The Issuer will, at the time of or at any
time after each exercise of this Warrant, upon the request of the Holder hereof,
acknowledge in writing the extent, if any, of its continuing obligation to
afford to such Holder all rights to which such Holder shall continue to be
entitled after such exercise in accordance with the terms of this Warrant,
provided that if any such Holder shall fail to make any such request, the
failure shall not affect the continuing obligation of the Issuer to afford such
rights to such Holder.

      (h) Compliance with Securities Laws.

            (i) The Holder of this Warrant, by acceptance hereof, acknowledges
      that this Warrant and 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 THE ISSUER
      SHALL HAVE RECEIVED AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE
      ISSUER THAT REGISTRATION OF SUCH SECURITIES UNDER THE SECURITIES ACT AND
      UNDER THE PROVISIONS OF APPLICABLE STATE SECURITIES LAWS IS NOT REQUIRED.


            (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. Such proposed transfer 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 and the Holder has represented that the Warrant Stock has
      been or will be sold, (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

<PAGE>

      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 three (3) business
      days. In the case of any proposed transfer under this Section 2(h), 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(h) 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, 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 DWAC system (to the extent not inconsistent with any
      provisions of this Warrant or the Purchase Agreement). Notwithstanding the
      foregoing to the contrary, the Issuer or its transfer agent shall only be
      obligated to issue and deliver the shares to the DTC on a holder's behalf
      via DWAC if such exercise is in connection with a sale and the Issuer and
      its transfer agent are participating in DTC through the DWAC system.

      (i) Accredited Investor Status. In no event may the Holder exercise this
Warrant in whole or in part unless the Holder is an "accredited investor" as
defined in Regulation D under the Securities Act.

<PAGE>

      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, when issued in accordance with the
terms of this Warrant, be duly authorized, validly issued, fully paid and
nonassessable 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 issuance upon exercise of this
Warrant a number of shares of Common Stock equal to at least one hundred ten
percent (110%) of the aggregate 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 best efforts as expeditiously as possible 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 Articles 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 Articles 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 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. The price at which such shares of Warrant
Stock 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 the notice provisions set forth in
Section 5.

      (a) Adjustments for Certain Specified Events. If at any time:

                  (1)   the Company does not execute a transaction with Chembio
                        and Inverness substantially on the same terms as those
                        outlined in the appendix to that certain Term Sheet
                        between the Company and Chardan Capital Markets dated
                        May 8, 2006, by midnight July 31st, 2006 or;
                  (2)   Chembio does not receive FDA Pre-Market Approval for the
                        manufacture of the StatSure Licensed Test by July 31st,
                        2006, then

      the Exercise Price shall be adjusted to $1.00 per share.

      (b) Adjustments for Stock Splits and Combinations. If the Company shall at
any time or from time to time after the Issuance Date, effect a stock split of
the outstanding Common Stock, the Exercise Price shall be proportionately
decreased. If the Company shall at any time or from time to time after the
Issuance Date, combine the outstanding shares of Common Stock, the Exercise
Price shall be proportionately increased. Any adjustments under this Section
4(b) shall be effective at the close of business on the date the stock split or
combination becomes effective

      (c) Adjustments for Certain Dividends and Distributions. If the Company
shall at any time or from time to time after the Issuance Date, make or issue or
set a record date for the determination of holders of Common Stock entitled to
receive a dividend or other distribution payable in shares of Common Stock,
then, and in each event, the Exercise Price shall be decreased as of the time of
such issuance or, in the event such record date shall have been fixed, as of the
close of business on such record date, by multiplying the Exercise Price then in
effect by a fraction:

<PAGE>

                  the numerator of which shall be the total number of shares of
Common Stock issued and outstanding immediately prior to the time of such
issuance or the close of business on such record date; and

                  the denominator of which shall be the total number of shares
of Common Stock issued and outstanding immediately prior to the time of such
issuance or the close of business on such record date plus the number of shares
of Common Stock issuable in payment of such dividend or distribution.

<PAGE>

      (d) Adjustment for Other Dividends and Distributions. If the Company shall
at any time or from time to time after the Issuance Date, make or issue or set a
record date for the determination of holders of Common Stock entitled to receive
a dividend or other distribution payable in securities of the Company other than
shares of Common Stock, then, and in each event, an appropriate revision to the
applicable Exercise Price shall be made and provision shall be made (by
adjustments of the Exercise Price or otherwise) so that the holders of the
Warrants shall receive upon exercise thereof, in addition to the number of
shares of Common Stock receivable thereon, the number of securities of the
Company which they would have received had their Warrants been exercised on the
date of such event and had thereafter, during the period from the date of such
event to and including the Exercise Date, retained such securities (together
with any distributions payable thereon during such period), giving application
to all adjustments called for during such period under this Section 4(d) with
respect to the rights of the holders; provided, however, that if such record
date shall have been fixed and such dividend is not fully paid or if such
distribution is not fully made on the date fixed therefor, the Exercise Price
shall be adjusted pursuant to this paragraph as of the time of actual payment of
such dividends or distributions; and provided further, however, that no such
adjustment shall be made if the holders simultaneously receive (i) a dividend or
other distribution of shares of Common Stock in a number equal to the number of
shares of Common Stock as they would have received if all outstanding Warrants
had been exercised on the date of such event or (ii) a dividend or other
distribution of shares equal to the number of additional shares of Common Stock
being issued with respect to each share of Common Stock in such dividend or
distribution.

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

<PAGE>

            (i) In case the Issuer after the Original Issue Date shall do any of
      the following (each, a "Triggering Event"): (a) consolidate or merge with
      or 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 (including
      the right of a shareholder to elect the type of consideration it will
      receive upon a Triggering Event), subject to adjustments (subsequent to
      such corporate action) as nearly equivalent as possible to the adjustments
      provided for elsewhere in this Section 4; provided, however, in the event
      that the Per Share Market Value is less than the Warrant Price at the time
      of such Triggering Event, the Holder shall receive an amount in cash equal
      to the value of this Warrant calculated in accordance with the
      Black-Scholes formula. Notwithstanding the foregoing to the contrary, this
      Section 4(e)(i) shall only apply if the surviving entity pursuant to any
      such Triggering Event is a company that has a class of equity securities
      registered pursuant to the Securities Exchange Act of 1934, as amended,
      and its common stock is listed or quoted on a national securities
      exchange, national automated quotation system or the OTC Bulletin Board.
      In the event that the surviving entity pursuant to any such Triggering
      Event is not a public company that is registered pursuant to the
      Securities Exchange Act of 1934, as amended, or its common stock is not
      listed or quoted on a national securities exchange, national automated
      quotation system or the OTC Bulletin Board, then the Holder shall have the
      right to demand that the Issuer pay to the Holder an amount in cash equal
      to the value of this Warrant calculated in accordance with the
      Black-Scholes formula.

<PAGE>

            (ii) Notwithstanding anything contained in this Warrant to the
      contrary and so long as the surviving entity pursuant to any Triggering
      Event is a company that has a class of equity securities registered
      pursuant to the Securities Exchange Act of 1934, as amended, and its
      common stock is listed or quoted on a national securities exchange,
      national automated quotation system or the OTC Bulletin Board, 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 (b), 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
      (b)) 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.


      (f)   Issuance of Additional Shares of Common Stock.

                  (i) For a period of three (3) years following the Original
            Issue Date, in the event the Issuer shall at any time following the
            Original Issue Date issue any Additional Shares of Common Stock
            (otherwise than as provided in the foregoing subsections (b) through
            (d)) 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 the same price as
            the Additional Shares of Common Stock.

                  (ii) For a period of two (2) years following the three-year
            period described above in the foregoing subsection (f)(i), in the
            event the Issuer shall at any time following the Original Issue Date
            issue any Additional Shares of Common Stock (otherwise than as
            provided in the foregoing subsections (b) through (e)) 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 (rounded to the nearest whole
            share) 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
                  (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.

<PAGE>

                  (iii) No adjustment of the number of shares of Common Stock
            for which this Warrant shall be exercisable shall be made under
            paragraph (i) or (ii) of Section 4(f) 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 therefore) pursuant to Section 4(g).

(g) Issuance of Common Stock Equivalents. For a period of three (3) years
following the Original Issue Date and then the following two (2) year period, 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, or if, after any such issuance of Common Stock
Equivalents, the price per share for which Additional Shares of Common Stock may
be issuable thereafter is amended or adjusted, and such price as so amended
shall be less than the Warrant Price in effect at the time of such amendment or
adjustment, then the Warrant Price then in effect shall be adjusted as provided
in Section 4(f). 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.


(h) 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(f) as the result
of any issuance of Common Stock Equivalents, and (i) such Common Stock
Equivalents, or the right of conversion or exchange in such Common Stock
Equivalents, shall expire, and all or a portion of such or the right of
conversion or exchange with respect to all or a portion of such 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, then 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), 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 theretofore actually issued or
issuable pursuant to the previous exercise of Common Stock Equivalents 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
therefore, 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 Additional Shares of Common
Stock 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.

<PAGE>

      (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). In connection with any merger or consolidation in which the
Issuer is the surviving corporation (other than any consolidation or merger in
which the previously outstanding shares of Common Stock of the Issuer shall be
changed to or exchanged for the stock or other securities of another
corporation), the amount of consideration therefore shall be, deemed to be the
fair value, as determined reasonably and in good faith by the Board, of such
portion of the assets and business of the nonsurviving corporation as the Board
may determine to be attributable to such shares of Common Stock or Common Stock
Equivalents, 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 the event
of any consolidation or merger of the Issuer in which the Issuer is not the
surviving corporation or in which the previously outstanding shares of Common
Stock of the Issuer shall be changed into or exchanged for the stock or other
securities of another corporation, or in the event of any sale of all or
substantially all of the assets of the Issuer for stock or other securities of
any corporation, the Issuer shall be deemed to have issued a number of shares of
its Common Stock for stock or securities or other property of the other
corporation computed on the basis of the actual exchange ratio on which the
transaction was predicated, and for a consideration equal to the fair market
value on the date of such transaction of all such stock or securities or other
property of the other corporation. In the event any consideration received by
the Issuer for any securities consists of property other than cash, the fair
market value thereof at the time of issuance or as otherwise applicable shall be
as determined in good faith by the Board. In the event Common Stock is issued
with other shares or securities or other assets of the Issuer for consideration
which covers both, the consideration computed as provided in this Section
4(h)(i) shall be allocated among such securities and assets as determined in
good faith by the Board.

<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(c)) 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.

            (v) Certain Issues Excepted. Anything herein to the contrary
notwithstanding, the Company shall not be required to make any adjustment to the
Exercise Price upon (i) securities issued (other than for cash) in connection
with a merger, acquisition, or consolidation, (ii) securities issued pursuant to
the conversion or exercise of convertible or exercisable securities issued or
outstanding on or prior to the date of the Purchase Agreement or issued pursuant
to the Purchase Agreement (so long as the conversion or exercise price in such
securities are not amended to lower such price and/or adversely affect the
holders), (iii) securities issued in connection with bona fide strategic license
agreements or other partnering arrangements so long as such issuances are not
primarily for the purpose of raising capital, (iv) Common Stock issued or the
issuance or grants of options to purchase Common Stock pursuant to the Issuer's
stock option plans and employee stock purchase plans outstanding as they exist
on the date of the Purchase Agreement, (v) Common Stock issued as payment of
dividends on the Series A Preferred Stock and (vi) any warrants issued to the
placement agent and its designees for the transactions contemplated by the
Purchase Agreement.

<PAGE>

      (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.

      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. Any dispute between the Issuer and the Holder of
this Warrant with respect to the matters set forth in such certificate may at
the option of the Holder of this Warrant be submitted to a national or regional
accounting firm reasonably acceptable to the Issuer and the Holder, provided
that the Issuer shall have ten (10) days after receipt of notice from such
Holder of its selection of such firm to object thereto, in which case such
Holder shall select another such firm and the Issuer shall have no such right of
objection. The firm selected by the Holder of this Warrant as provided in the
preceding sentence shall be instructed to deliver a written opinion as to such
matters to the Issuer and such Holder within thirty (30) days after submission
to it of such dispute. Such opinion shall be final and binding on the parties
hereto. The costs and expenses of the initial accounting firm shall be paid
equally by the Issuer and the Holder and, in the case of an objection by the
Issuer, the costs and expenses of the subsequent accounting firm shall be paid
in full by the Issuer.

<PAGE>

      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 round the number of shares to be issued upon exercise up to the
nearest whole number of shares.

      7. Ownership Cap and Exercise Restriction. 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 beneficially owning (as determined in
accordance with Section 13(d) of the Exchange Act and the rules thereunder) in
excess of 4.99% of the then issued and outstanding shares of Common Stock;
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 with regard to any or all
shares of Common Stock issuable upon exercise of this Warrant, this Section 7
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 during the sixty-one (61) days immediately
preceding the expiration of the term of this Warrant.

      11. Amendment and Waiver. Any term, covenant, agreement or condition in

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 11 without the consent of the Holder of this Warrant.

waiver or modification of any provision of this Warrant unless the same
consideration is also offered to all holders of the Warrants.

      12. Governing Law; Jurisdiction. This Warrant shall be governed by and
construed in accordance with the internal laws of the State of New York, without

causing this Warrant to be drafted. The Issuer and the Holder agree that venue
for any dispute arising under this Warrant will lie exclusively in the state or
federal courts located in Middlesex County, Massachusetts and the parties
irrevocably waive any right to raise forum non conveniens or any other argument
that Massachusetts is not the proper venue. The Issuer and the Holder
irrevocably consent to personal jurisdiction in the state and federal courts of
the state of Massachusetts. The Issuer and the Holder consent to process being
served in any such suit, action or proceeding by mailing a copy thereof to such
party at the address in effect for notices to it under this Warrant and agrees
that such service shall constitute good and sufficient service of process and
notice thereof. Nothing in this Section 12 shall affect or limit any right to
serve process in any other manner permitted by law. The Issuer and the Holder
hereby agree that the prevailing party in any suit, action or proceeding arising
out of or relating to this Warrant or the Purchase Agreement, shall be entitled
