     or instruments of transfer in form satisfactory to it, duly executed by the

     representative thereof. Upon any such registration of transfer, new Warrant
     Certificate(s) evidencing such transferred Warrants shall be issued to the
     transferee(s) and the surrendered Warrant Certificate(s) shall be canceled.

     surrendered for transfer are to be transferred, new Warrant Certificate(s)
     shall be issued to the holder surrendering such Warrant Certificate(s)
     evidencing such

                                        5
<PAGE>

     holder(s) thereof, when surrendered to the Issuer at the Warrant Office,
     for another Warrant Certificate or other Warrant Certificates of like tenor
     and representing in the aggregate a like number of Warrants. Warrant
     Certificates surrendered for exchange shall be canceled.

          (d) No charge shall be made for any such transfer or exchange except
     for any tax or other governmental charge imposed in connection therewith.
     Except as provided in Section 13(b) hereof, each Warrant Certificate issued
     upon transfer or exchange shall bear the legend set forth in Section 13(b)
     hereof if the Warrant Certificate presented for transfer or exchange bore
     such legend.

     SECTION 5. Mutilated or Missing Warrant Certificates. If any Warrant
Certificate shall be mutilated, lost, stolen or destroyed, the Issuer shall
issue, in exchange and substitution for and upon cancellation of the mutilated
Warrant Certificate, or in lieu of and substitution for the Warrant Certificate
lost, stolen or destroyed, a new Warrant Certificate of like tenor and
representing an equivalent number of Warrants, but only upon receipt of evidence
satisfactory to the Issuer of such loss, theft or destruction of such Warrant
Certificate and, if reasonably requested, indemnity satisfactory to it. No
service charge shall be made for any such substitution, but all expenses and
reasonable charges associated with procuring such indemnity and all stamp, tax
and other governmental duties that may be imposed in relation thereto shall be
borne by the holder of such Warrant Certificate. Each Warrant Certificate issued
in any such substitution shall bear the legend set forth in Section 13(b) hereof
if the Warrant Certificate for which such substitution was made bore such
legend.

     SECTION 6. Duration and Exercise of Warrants.

          (a) The Warrants evidenced by a Warrant Certificate shall be
     exercisable in whole or in part by the registered holder thereof on any
     Business Day at any time from and after the date of the Closing and prior
     to 5:00 P.M. in New York City on the Expiration Date.

          (b) Subject to the provisions of this Warrant Agreement, upon
     presentation of the Warrant Certificate evidencing the Warrants to be
     exercised, with the form of election to purchase on the reverse thereof
     duly completed and signed by the registered holder or holders thereof, to
     the Issuer at the Warrant Office, and upon payment of the aggregate
     Exercise Price for the number of Warrant Shares in respect of which such
     Warrants are being exercised in lawful money of the United States of
     America, the Issuer shall issue and cause to be delivered to or upon the
     written order of the registered holder(s) of such Warrants

                                        6
<PAGE>
     and in such name or names as such registered holder(s) may designate, a
     certificate for the Warrant Shares issued upon such exercise of such
     Warrants. Any Person(s) so designated to be named therein shall be deemed
     to have become holder(s) of record of such Warrant Shares as of the date of
     exercise of such Warrants. Certificates for the Warrant Shares so
     purchased, representing the aggregate number of shares specified in the
     Warrant Certificate, shall be delivered to the registered holder within a
     reasonable time, not exceeding three (3) Business Days, after this Warrant
     shall have been so exercised. The certificates so delivered shall be in
     such denominations as may be requested by the registered holder and shall
     be registered in the name of the registered holder or such other name as
     shall be designated by such registered holder.

          (c) If less than all of the Warrants evidenced by a Warrant
     Certificate are exercised at any time, a new Warrant Certificate or
     Certificates shall be issued for the remaining number of Warrants evidenced
     by such Warrant Certificate. Each new Warrant Certificate so issued shall
     bear the legend set forth in Section 13(b) hereof if the Warrant
     Certificate presented in connection with partial exercise thereof bore such
     legend. All Warrant Certificates surrendered upon exercise of Warrants
     shall be canceled.

          (d) Notwithstanding the foregoing, at any time after the six-month
     anniversary of the date hereof, the Issuer may, at its sole option, compel
     the involuntary conversion of all, but not less than all, of the
     outstanding Warrants into Warrant Shares at the Exercise Price in the event
     that (i) the Current Market Price Per Share (as hereinafter defined) is
     equal to or in excess of two hundred percent (200%) of the Exercise Price
     per Warrant Share for a period of at least twenty consecutive Trading Days,
     (ii) the Warrant Shares have been registered under the Securities Act
     pursuant to Section 6.1 of the Stock Purchase Agreement and such
     registration has been declared effective by the Commission and is effective
     on such date and (iii) the Issuer has a sufficient number of authorized
     shares of Common Stock reserved for issuance upon conversion of the
     Warrants. In the event that the Issuer elects to compel such involuntary
     conversion of all outstanding Warrants, it shall promptly notify the
     Warrant Holder of such election at least ten (10) days in advance of the
     date set forth in such conversion notice whereupon the Warrants shall be
     deemed converted into shares of Common Stock as of the date set forth in
     the Issuer's conversion notice.

          (e) In lieu of physical delivery of the Warrants, provided that
     Issuer's transfer agent is participating in The Depository Trust Company
     ("DTC") Shares Fast Automated Securities Transfer ("FAST") program, upon
     request of the Warrant Holder and in compliance with the provisions hereof,
     the Issuer shall use its best efforts to cause its transfer agent to
     electronically transmit the Warrant Shares to the Warrant Holder by
     crediting the account of the Warrant Holder's prime broker

                                        7
<PAGE>
     with DTC through its Deposit Withdrawal Agent Commission system. The time
     period for delivery described herein shall apply to the electronic
     transmittals described herein.

     SECTION 7. No Fractional Shares. The Issuer shall not be required to issue
fractional shares of Common Stock upon exercise of the Warrants but may pay for
any such fraction of a share an amount in cash equal to the Current Market Price
per Share of Common Stock of such share multiplied by such fraction. The
"Current Market Price Per Share" on any date shall be deemed to be, for any day,
the last bid price for the Common Stock on the principal securities exchange on
which the Common Stock is listed or admitted to trading, or, if not so listed or
admitted to trading on any securities exchange, the last sale price for the
Common Stock on the National Association of Securities Dealers National Market
System, or, if the Common Stock shall not be listed on such system, the closing
bid price of the Common Stock in the over-the-counter market.

applicable income or similar taxes payable by the holders of the Warrants or
Warrant Shares) attributable to the initial issuance of Warrant Shares upon the
exercise of the Warrants; provided that the Issuer shall not be required to pay
any tax which may be payable in respect of any transfer involved in the issue of
any Warrant Certificate or any certificate for Warrant Shares in a name other
than that of the registered holder of a Warrant Certificate surrendered upon the
exercise of a Warrant, and the Issuer shall not be required to issue or deliver
such certificates unless or until the Person or Persons requesting the issuance
thereof shall have paid to the Issuer the amount of such tax or shall have
established to the satisfaction of the Issuer that such tax has been paid.

     SECTION 9. Reservation and Issuance of Warrant Shares.

          (a) The Issuer will at all times have authorized, and reserve and keep
     available for the purpose of enabling it to satisfy any obligation to issue
     Warrant Shares upon the exercise of the Warrants, the number of shares of
     Common Stock deliverable upon exercise of all outstanding Warrants.

          (b) Before taking any action which would cause an adjustment pursuant
     to Section 11 hereof reducing the Exercise Price below the then par value
     (if any) of the Warrant Shares issuable upon exercise of the Warrants, the
     Issuer will take any corporate action which may be necessary in order that
     the Issuer may validly and legally issue fully paid and nonassessable
     Warrant Shares at the Exercise Price as so adjusted.

          (c) The Issuer covenants that all Warrant Shares will, upon issuance
     in accordance with the terms of this Warrant Agreement, be duly and validly
     issued,

                                        8
<PAGE>
     fully paid and nonassessable and free from all taxes with respect to the
     issuance thereof and from all liens, charges and security interests created
     (whether by affirmative action or inaction) by the Issuer and shall not
     have any legends or restrictions on resale, except as required by Section
     13(b) hereof.

          (d) The Issuer shall promptly secure the listing of the shares of
     Common Stock issuable upon exercise of the Warrants upon the national
     securities exchange or automated quotation system, if any, upon which
     shares of Common Stock are then listed (subject to official notice of
     issuance upon exercise of the Warrants) and shall maintain, so long as any
     other shares of Common Stock shall be so listed, such listing of all shares
     of Common Stock from time to time issuable upon the exercise of the
     Warrants.

     SECTION 10. Obtaining of Governmental Approvals and Stock Exchange
Listings. The Issuer will, at its own expense, (a) obtain and keep effective any
and all permits, consents and approvals of governmental agencies and authorities
which may from time to time be required of the Issuer in order to satisfy its
obligations hereunder and (b) take all action which may be necessary so that the
Warrant Shares, immediately upon their issuance upon the exercise of the
Warrants, will be listed on each securities exchange or over-the-counter market,
if any, on which the Common Stock is then listed if such listing is permitted by
applicable law, regulation or rule.

     SECTION 11. Adjustment of Exercise Price and Number of Warrant Shares
Purchasable. Prior to the Expiration Date, the Exercise Price and the number of
Warrant Shares purchasable upon the exercise of each Warrant are subject to
adjustment from time to time upon the occurrence of any of the events enumerated
in this Section 11.

          (a) In the event that the Issuer shall at any time after the date of
     this Agreement (i) declare a dividend on the Common Stock in Common Stock,
     Convertible Securities or other Rights, (ii) split or subdivide the
     outstanding Common Stock, (iii) combine the outstanding Common Stock into a
     smaller number of shares, or (iv) issue by reclassification of its Common
     Stock any shares of Common Stock, Convertible Securities or other Rights,
     then, in each such event, the number of Warrant Shares purchasable upon
     exercise of each Warrant immediately prior thereto shall be adjusted so
     that the holder shall be entitled to receive the kind and number of such
     shares or other securities of the Issuer which the holder would have owned
     or have been entitled to receive after the happening of any of the events
     described above, had such Warrant been exercised immediately prior to the
     happening of such event (or any record date with respect thereto). Such
     adjustment shall be made whenever any of the events listed above shall
     occur. An adjustment made pursuant to this paragraph (a) shall become
     effective immediately after the effective date of the event retroactive to
     the record date, if any, for the event.

                                        9
<PAGE>
          (b) If at any time, as a result of an adjustment made pursuant to this
     Section 11, the holder of any Warrant thereafter exercised shall become
     entitled to receive any shares of the Issuer other than shares of Common
     Stock, thereafter the number of such other shares so receivable upon
     exercise of any Warrant shall be subject to adjustment from time to time in
     a manner and on terms as nearly equivalent as practicable to the provisions
     with respect to the Warrant Shares contained in this Section 11, and the
     provisions of this Agreement with respect to the Warrant Shares shall apply
     on like terms to such other shares.

          (c) Whenever the number of Warrant Shares purchasable upon the
     exercise of each warrant is adjusted pursuant to Section 11(a) hereof, the
     Exercise Price per Warrant Share payable upon exercise of each Warrant
     shall be adjusted by multiplying such Exercise Price immediately prior to
     such adjustment by a fraction, the numerator of which shall be the number
     of Warrant Shares purchasable upon the exercise of each Warrant immediately
     prior to such adjustment, and the denominator of which shall be the number
     of Warrant Shares purchasable immediately after such adjustment; provided,
     however, that in no event shall the Exercise Price be adjusted to an amount
     which is less than the par value of the Common Stock.

          (d) In the event of any capital reorganization of the Issuer, or of
     any reclassification of the Common Stock (other than a reclassification
     referred to in Section 11(a)(iv) above), or in case of the consolidation of
     the Issuer with or the merger of the Issuer with or into any other
     corporation or of the sale of the properties and assets of the Issuer as,
     or substantially as, an entirety to any other Person, each Warrant shall,
     after such capital reorganization, reclassification of Common Stock,
     consolidation, merger or sale, and in lieu of being exercisable for Warrant
     Shares, be exercisable, upon the terms and conditions specified in this
     Warrant Agreement, for the number of shares of stock or other securities or
     assets to which a holder of the number of Warrant Shares purchasable (at
     the time of such capital reorganization, reclassification of Common Stock,
     consolidation, merger or sale) upon exercise of such Warrant would have
     been entitled upon such capital reorganization, reclassification of Common
     Stock, consolidation, merger or sale; and in any such case, if necessary,
     the provisions set forth in this Section 11 with respect to the rights
     thereafter of the holders of the Warrants shall be appropriately adjusted
     so as to be applicable, as nearly as they may reasonably be, to any shares
     of stock or other securities or assets thereafter deliverable on the
     exercise of the Warrants. The Issuer shall not effect any such
     consolidation, merger or sale, unless prior to or simultaneously with the
     consummation thereof the successor corporation (if other than the Issuer)
     resulting from such consolidation or merger or the corporation purchasing
     such assets or the appropriate corporation or entity shall assume, by
     written instrument, the obligation to deliver to the holder of each Warrant
     the shares of stock, securities or assets to which, in accordance with the

                                       10
<PAGE>
     foregoing provisions, such holder may be entitled and all other obligations
     of the Issuer under this Warrant Agreement. The provisions of this
     paragraph (d) shall apply to successive reorganizations, reclassifications,
     consolidations, mergers and sales.

          (e) Except with respect to Excluded Securities (as defined below), in
     case the Issuer shall issue any shares of Common Stock or Convertible
     Securities after the date hereof at a price per share (or having a
     conversion or exercise price per share) of less than the Exercise Price per
     Warrant Share, the Exercise Price per Warrant Share shall be appropriately
     adjusted by decreasing (but not increasing) the Exercise Price per Warrant
     Share to such lower price per share. An adjustment made pursuant to clause
     (a) shall be made the next Business Day following the date on which any
     such issuance is made and shall be effective retroactively to the close of
     business on the date of such issuance. For purposes of this clause (e), the
     consideration receivable by the Issuer in connection with the issuance of
     additional shares of Common Stock or of Convertible Securities after the
     date hereof shall be deemed to be equal to (X) in the case the
     consideration received by the Issuer is cash, the sum of the aggregate
     offering price (before deduction of underwriting discounts or commissions
     and expenses payable to third parties, if any) of all such Common Stock
     and/or Convertible Securities plus the minimum aggregate amount, if any,
     payable upon conversion, exchange or exercise of any such Convertible
     Securities, and (Y) in the case the consideration received by the Issuer is
     other than cash, the fair market value of the consideration received by the
     Issuer as determined by the good faith judgment of the Board of Directors
     of the Issuer; provided, however, that in the event the Warrant Holder
     disagrees in good faith with the determination of the Board of Directors of
     the Issuer, such fair market value shall be determined by a nationally
     recognized or major regional investment banking firm or firm of independent
     certified public accountants of recognized standing (an "Appraiser")
     selected in good faith by the Warrant Holder; and provided, further, that
     the Issuer, after receipt of the determination by such Appraiser shall have
     the right to select in good faith an additional Appraiser meeting the same
     qualifications, in which case the fair market value shall be equal to the
     average of the determinations by each such Appraiser. The issuance or
     reissuance of any shares of Common Stock or Convertible Securities (whether
     treasury shares or newly issued shares) pursuant to a dividend or
     distribution on, or subdivision, combination or reclassification of, the
     outstanding shares of Common Stock requiring an adjustment in the Exercise
     Price per Warrant Share pursuant to clause (a), shall not be deemed to
     constitute an issuance of Common Stock or Convertible Securities by the
     Issuer pursuant to which this clause (e) applies. Upon the expiration or
     termination of any unconverted, unexchanged or unexercised Convertible
     Securities for which an adjustment has been made pursuant to this clause
     (e), the adjustments shall forthwith be reversed to effect such Exercise
     Price per Warrant Share as would have been in effect at the time of

                                       11
<PAGE>
     such expiration or termination had such Convertible Securities, to the
     extent outstanding immediately prior to such expiration or termination, had
     never been issued. For purposes of this clause (e), "Excluded Securities"
     shall mean: (i) shares of Common Stock issuable upon conversion of the
     Preferred Stock; (ii) shares of Common Stock issuable or issued to
     employees of and consultants to the Issuer pursuant to the Management
     Option Plan; (iii) any capital stock issued as a stock dividend or upon any
     stock split or other subdivision or combination of shares of the Issuer's
     capital stock; (iv) shares of Common Stock issuable upon conversion of any
     Convertible Securities issued prior to the date hereof and outstanding on
     the date hereof, (v) shares of Common Stock issuable upon conversion of the
     Issuer's Class A Convertible Preferred Stock outstanding on the date hereof
     or (vi) Common Stock issued upon the conversion or exercise of Convertible
     Securities issued after the date hereof as to which an adjustment to the
     Exercise Price per Warrant Share has been made pursuant to this clause (e)
     upon the issuance of such Convertible Securities.

          (f) Irrespective of any adjustments in the Exercise Price or the
     number or kind of shares purchasable upon exercise of the Warrants, Warrant
     Certificates theretofore or thereafter issued may continue to express the
     same Exercise Price per share and number and kind of shares as are stated
     on the Warrant Certificates initially issuable pursuant to this Agreement.

          (g) If any question shall at any time arise with respect to the
     adjusted Exercise Price or Warrant Shares issuable upon exercise, such
     question shall be determined by the independent auditors of the Issuer and
     such determination shall be binding upon the Issuer and the holders of the
     Warrants and the Warrant Shares.

     SECTION 12. Notices to the Warrant Holder. Upon any adjustment of the
Exercise Price or number of Warrant Shares issuable upon exercise pursuant to
Section 11 hereof the Issuer shall promptly, but in any event within ten
Business Days thereafter, cause to be given to the Warrant Holder, at its
address appearing on the Warrant Register by first- class mail, postage prepaid,
a certificate signed by its chief financial officer setting forth the Exercise
Price as so adjusted and/or the number of shares of Common Stock issuable upon
the exercise of each Warrant as so adjusted and describing in reasonable detail
the facts accounting for such adjustment and the method of calculation used.
Where appropriate, such certificate may be given in advance and included as a
part of the notice required to be mailed under the other provisions of this
Section 12.

     In the event:

          (a) the Issuer shall authorize issuance to all holders of Common Stock
     of rights or warrants to subscribe for or purchase Capital Stock of the
     Issuer or of any

                                       12
<PAGE>
         other subscription rights or warrants; or

          (b) the Issuer shall authorize a dividend or other distribution to all
     holders of Common Stock payable in evidences of its indebtedness, cash or
     assets; or

          (c) of any consolidation or merger to which the Issuer is a party and
     for which approval of any stockholders of the Issuer is required, or of the
     conveyance or transfer of the properties and assets of the Issuer
     substantially as an entirety, or of any capital reorganization or
     reclassification or change 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, or as a result of a subdivision or combination); or

          (d) of the voluntary or involuntary dissolution, liquidation or
     winding up of the Issuer; or

          (e) the Issuer shall authorize any other action which would require an
     adjustment of the Exercise Price or number of Warrant Shares issuable upon
     exercise pursuant to Section 11 hereof;

then the Issuer shall cause to be given to the Warrant Holder at its address
appearing on the Warrant Register, at least twenty (20) Business Days prior to
the applicable record date hereinafter specified (or as expeditiously as
possible after the occurrence of any involuntary dissolution, liquidation or
winding up referred to in clause (d) above), by first- class mail, postage
prepaid, a written notice stating (i) the date as of which the holders of record
of Common Stock to be entitled to receive any such rights, warrants or
distribution are to be determined, or (ii) the date on which any such
consolidation, merger, conveyance, transfer, dissolution, liquidation or winding
up is expected to become effective (or has become effective, in the case of any
involuntary dissolution, liquidation or winding up), and the date as of which it
is expected that holders of record of Common Stock shall be entitled to exchange
their shares for securities or other property, if any, deliverable upon such
reclassification, consolidation, merger, conveyance, transfer, dissolution,
liquidation or winding up. The failure to give the notice required by this
Section 12 or any defect therein shall not affect the legality or validity of
any distribution, right, warrant, consolidation, merger, conveyance, transfer,
dissolution, liquidation or winding up, or the vote upon any action.

          SECTION 13. Restrictions on Transfer.

          (a) The Warrant Holder represents that it is not acquiring the
     Warrants (and upon any exercise of the Warrants, each holder represents
     that it will not be acquiring the Warrant Shares) with a view to any
     distribution or public offering within the meaning of the Securities Act
     but subject to any requirement of law that the disposition of its property
     shall at all times be within its control. The Warrant

                                       13
<PAGE>
     Holder acknowledges that the Warrant Shares issuable upon exercise of the
     Warrants have not as of the date hereof been registered under the
     Securities Act and agrees that it will not sell or otherwise transfer any
     of its Warrant Shares except upon the terms and conditions specified
     herein.

          (b) (i) The Warrant Holder agrees, and each subsequent transferee
     described in paragraph (ii) below shall agree, that it will not transfer
     any Warrant Shares except pursuant to an exemption from, or otherwise in a
     transaction not subject to, the registration requirements of the Securities
     Act (as confirmed in an opinion of counsel reasonably acceptable to the
     Issuer to the transferor to the effect that the proposed transfer may be
     effected without registration under the Securities Act) or pursuant to an
     effective registration statement under the Securities Act.

          (ii) Each Warrant Certificate and each certificate for the Warrant
     Shares (unless the legal opinion delivered in connection therewith is to
     the effect that the first paragraph of such legend is not required in order
     to ensure compliance with the Securities Act) shall include a legend in
     substantially the following form:

     THE WARRANTS AND UNDERLYING SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT

     This Warrant Certificate certifies that __________________________
_________________________________________, or registered assigns, is the
registered holder of ____ Warrants (the "Warrants") to purchase Common Stock,
$.001 par value (the "Common Stock"), of CHROMATICS COLOR SCIENCES

Warrants shall be issued in exchange for this Warrant Certificate to the
transferee(s) and, if less than all the Warrants evidenced hereby are to be
transferred, to the registered holder hereof, subject to the limitations
provided in the Warrant Agreement, without charge except for any tax or other
governmental charge imposed in connection therewith.

     This Warrant Certificate is one of the Warrant Certificates referred to in
the Warrant Agreement, dated as of February 11, 2000, by and between the Issuer
and the Warrant Holder named therein (the "Warrant Agreement"). Said Warrant

Certificate and is hereby referred to for a description of the rights,
limitation of rights, obligations, duties and immunities thereunder of the
