                             STOCK PURCHASE WARRANT

                To Purchase __________ Shares of Common Stock of

                               Pharmos Corporation

            THIS STOCK PURCHASE WARRANT CERTIFIES that, for value received,
      _____________ (the "Holder"), is entitled, upon the terms and subject to
      the limitations on exercise and the conditions hereinafter set forth, at
      any time on or after June 2, 2003 (the "Initial Exercise Date") and on or
      prior to the close of business on the five-year anniversary of the Initial
      Exercise Date (the "Termination Date") but not thereafter, to subscribe
      for and purchase from Pharmos Corporation, a corporation incorporated in
      the State of Nevada (the "Company"), up to ____________ shares (the
      "Warrant Shares") of Common Stock, par value $0.03 per share, of the
      Company (the "Common Stock"). The purchase price of one share of Common
      Stock (the "Exercise Price") under this Warrant shall be $1.40, subject to
      adjustment hereunder. The Exercise Price and the number of Warrant Shares
      for which the Warrant is exercisable shall be subject to adjustment as
      provided herein. Capitalized terms used and not otherwise defined herein
      shall have the meanings set forth in that certain Securities Purchase
      Agreement (the "Purchase Agreement"), dated May 30, 2003, between the
      Company and the investors signatory thereto.


                                       1


            1. Title to Warrant. Prior to the Termination Date and subject to
compliance with applicable laws and Section 7 of this Warrant, this Warrant and
all rights hereunder are transferable, in whole or in part, at the office or
agency of the Company by the Holder in person or by duly authorized attorney,
upon surrender of this Warrant together with the Assignment Form annexed hereto
properly endorsed. The transferee shall sign an investment letter in form and
substance reasonably satisfactory to the Company.

            2. Authorization of Shares. The Company covenants that all Warrant
Shares which may be issued upon the exercise of the purchase rights represented
by this Warrant will, upon exercise of the purchase rights represented by this
Warrant, be duly authorized, validly issued, fully paid and nonassessable and
free from all taxes, liens and charges in respect of the issue thereof (other
than taxes in respect of any transfer occurring contemporaneously with such
issue).

      3. Exercise of Warrant.

                  (a) Except as provided in Section 4 herein, exercise of the
      purchase rights represented by this Warrant may be made at any time or
      times on or after the Initial Exercise Date and on or before the
      Termination Date by the surrender of this Warrant and the Notice of
      Exercise Form annexed hereto duly executed, at the office of the Company
      (or such other office or agency of the Company as it may designate by
      notice in writing to the registered Holder at the address of such Holder
      appearing on the books of the Company) and upon payment of the Exercise
      Price of the shares thereby purchased by wire transfer or cashier's check
      drawn on a United States bank or by means of a cashless exercise pursuant
      to Section 3(d). Upon such exercise, the Holder shall be entitled to
      receive a certificate for the number of Warrant Shares so purchased.
      Certificates for shares purchased hereunder shall be delivered to the
      Holder within five Trading Days after the date on which this Warrant shall
      have been exercised as aforesaid. Notwithstanding anything herein to the
      contrary, in lieu of issuing certificates for shares purchased hereunder,
      upon mutual agreement of the Company and the Holder, the Company may
      authorize its transfer agent to issue shares through electronic
      transactions. This Warrant shall be deemed to have been exercised and such
      certificate or certificates shall be deemed to have been issued, and
      Holder or any other person so designated to be named therein shall be
      deemed to have become a holder of record of such shares for all purposes,
      as of the date the Warrant has been exercised by payment to the Company of
      the Exercise Price and all taxes required to be paid by the Holder, if
      any, pursuant to Section 5 prior to the issuance of such shares, have been
      paid. If the Company fails to deliver to the Holder a certificate or
      certificates representing the Warrant Shares pursuant to this Section 3(a)
      by the fifth Trading Day after the date of exercise, then the Holder will
      have the right to rescind such exercise.

                  (b) If this Warrant shall have been exercised in part, the
      Company shall, at the time of delivery of the certificate or certificates
      representing Warrant Shares, deliver


                                       2


      to Holder a new Warrant evidencing the rights of Holder to purchase the
      unpurchased Warrant Shares called for by this Warrant, which new Warrant
      shall in all other respects be identical with this Warrant.

                  (c) Notwithstanding anything herein to the contrary, in no
      event shall the Holder be permitted to exercise this Warrant for Warrant
      Shares to the extent that (i) the number of shares of Common Stock
      beneficially owned by such Holder, together with any affiliate thereof
      (other than Warrant Shares issuable upon exercise of this Warrant) plus
      (ii) the number of Warrant Shares issuable upon exercise of this Warrant,
      would be equal to or exceed 4.9999% of the number of shares of Common
      Stock then issued and outstanding, including shares issuable upon exercise
      of this Warrant held by such Holder after application of this Section
      3(c). As used herein, beneficial ownership shall be determined in
      accordance with Section 13(d) of the Exchange Act and the rules
      promulgated thereunder. To the extent that the limitation contained in
      this Section 3(c) applies, the determination of whether this Warrant is
      exercisable (in relation to other securities owned by the Holder) and of
      which a portion of this Warrant is exercisable shall be in the sole
      discretion of such Holder, and the submission of a Notice of Exercise
      shall be deemed to be such Holder's determination of whether this Warrant
      is exercisable (in relation to other securities owned by such Holder) and
      of which portion of this Warrant is exercisable, in each case subject to
      such aggregate percentage limitation, and the Company shall have no
      obligation to verify or confirm the accuracy of such determination.
      Nothing contained herein shall be deemed to restrict the right of a Holder
      to exercise this Warrant into Warrant Shares at such time as such exercise
      will not violate the provisions of this Section 3(c). The provisions of
      this Section 3(c) may be waived by the Holder upon, at the election of the
      Holder, not less than 61 days' prior notice to the Company, and the
      provisions of this Section 3(c) shall continue to apply until such 61st
      day (or such later date, as determined by the Holder, as may be specified
      in such notice of waiver). No exercise of this Warrant in violation of
      this Section 3(c) but otherwise in accordance with this Warrant shall
      affect the status of the Warrant Shares as validly issued, fully-paid and
      nonassessable.

                  (d) If at any time after one year from the date of issuance of
      this Warrant there is no effective Registration Statement registering the
      resale of the Warrant Shares by the Holder, this Warrant may also be
      exercised at such time by means of a "cashless exercise" in which the
      Holder shall be entitled to receive a certificate for the number of
      Warrant Shares equal to the quotient obtained by dividing [(A-B) (X)] by
      (A), where:

            (A) = the average of the Closing Prices on the three Trading Days
                  immediately preceding the date of such election;

            (B) = the Exercise Price of the Warrants, as adjusted; and

            (X) = the number of Warrant Shares issuable upon exercise of the
                  Warrants in accordance with the terms of this Warrant.

            4. No Fractional Shares or Scrip. No fractional shares or scrip
representing


                                       3


fractional shares shall be issued upon the exercise of this Warrant. As to any
fraction of a share which Holder would otherwise be entitled to purchase upon
such exercise, the Company shall pay a cash adjustment in respect of such final
fraction in an amount equal to such fraction multiplied by the Exercise Price.

            5. Charges, Taxes and Expenses. Issuance of certificates for Warrant
Shares shall be made without charge to the Holder for any issue or transfer tax
or other incidental expense in respect of the issuance of such certificate, all
of which taxes and expenses shall be paid by the Company, and such certificates
shall be issued in the name of the Holder or in such name or names as may be
directed by the Holder; provided, however, that in the event certificates for
Warrant Shares are to be issued in a name other than the name of the Holder,
this Warrant when surrendered for exercise shall be accompanied by the
Assignment Form attached hereto duly executed by the Holder; and the Company may
require, as a condition thereto, the payment of a sum sufficient to reimburse it
for any transfer tax incidental thereto.

            6. Closing of Books. The Company will not close its stockholder
books or records in any manner which prevents the timely exercise of this
Warrant, pursuant to the terms hereof.

            7. Transfer, Division and Combination.

            (a) Subject to compliance with any applicable securities laws and
      the conditions set forth in Sections 1 and 7(f) hereof and to the
      provisions of Section 4.1 of the Purchase Agreement, this Warrant and all
      rights hereunder are transferable, in whole or in part, upon surrender of
      this Warrant at the principal office of the Company, together with a
      written assignment of this Warrant substantially in the form attached
      hereto duly executed by the Holder or its agent or attorney and funds
      sufficient to pay any transfer taxes payable upon the making of such
      transfer. Upon such surrender and, if required, such payment, the Company
      shall execute and deliver a new Warrant or Warrants in the name of the
      assignee or assignees and in the denomination or denominations specified
      in such instrument of assignment, and shall issue to the assignor a new
      Warrant evidencing the portion of this Warrant not so assigned, and this
      Warrant shall promptly be cancelled. A Warrant, if properly assigned, may
      be exercised by a new holder for the purchase of Warrant Shares without
      having a new Warrant issued.

            (b) This Warrant may be divided or combined with other Warrants of
      like tenor and terms upon presentation hereof at the aforesaid office of
      the Company, together with a written notice specifying the names and
      denominations in which new Warrants are to be issued, signed by the Holder
      or its agent or attorney. Subject to compliance with Section 7(a), as to
      any transfer which may be involved in such division or combination, the
      Company shall execute and deliver a new Warrant or Warrants in exchange
      for the Warrant or Warrants to be divided or combined in accordance with
      such notice.


                                       4


            (c) The Company shall prepare, issue and deliver at its own expense
      (other than transfer taxes) the new Warrant or Warrants under this Section
      7.

            (d) The Company agrees to maintain, at its aforesaid office, books
      for the registration and the registration of transfer of the Warrants.

            (e) If, at the time of the surrender of this Warrant in connection
      with any transfer of this Warrant, the transfer of this Warrant shall not
      be registered pursuant to an effective registration statement under the
      Securities Act and under applicable state securities or blue sky laws, the
      Company may require, as a condition of allowing such transfer (i) that the
      Holder or transferee of this Warrant, as the case may be, furnish to the
      Company a written opinion of counsel (which opinion shall be in form,
      substance and scope customary for opinions of counsel in comparable
      transactions) to the effect that such transfer may be made without
      registration under the Securities Act and under applicable state
      securities or blue sky laws, (ii) that the holder or transferee execute
      and deliver to the Company an investment letter in form and substance
      acceptable to the Company and (iii) that the transferee be an "accredited
      investor" as defined in Rule 501(a) promulgated under the Securities Act.

            8. No Rights as Shareholder until Exercise. This Warrant does not
entitle the Holder to any voting rights or other rights as a shareholder of the
Company prior to the exercise hereof. Upon the surrender of this Warrant and the
payment of the aggregate Exercise Price (or by means of a cashless exercise),
the Warrant Shares so purchased shall be and be deemed to be issued to such
Holder as the record owner of such shares as of the close of business on the
later of the date of such surrender or payment.

            9. Loss, Theft, Destruction or Mutilation of Warrant. The Company
covenants that upon receipt by the Company of evidence reasonably satisfactory
to it of the loss, theft, destruction or mutilation of this Warrant or any stock
certificate relating to the Warrant Shares, and in case of loss, theft or
destruction, of indemnity or security reasonably satisfactory to it (which, in
the case of the Warrant, shall not include the posting of any bond), and upon
surrender and cancellation of such Warrant or stock certificate, if mutilated,
the Company will make and deliver a new Warrant or stock certificate of like
tenor and dated as of such cancellation, in lieu of such Warrant or stock
certificate.

            10. Saturdays, Sundays, Holidays, etc. If the last or appointed day
for the taking of any action or the expiration of any right required or granted
herein shall be a Saturday, Sunday or a legal holiday, then such action may be
taken or such right may be exercised on the next succeeding day not a Saturday,
Sunday or legal holiday.

            11. Adjustments of Exercise Price and Number of Warrant Shares;
Stock Splits, etc. The number and kind of securities purchasable upon the
exercise of this Warrant and the Exercise Price shall be subject to adjustment
from time to time upon the happening of any of the following. In case the
Company shall (i) pay a dividend in shares of Common Stock or make


                                       5


a distribution in shares of Common Stock to holders of its outstanding Common
Stock, (ii) subdivide its outstanding shares of Common Stock into a greater
number of shares, (iii) combine its outstanding shares of Common Stock into a
smaller number of shares of Common Stock, or (iv) issue any shares of its
capital stock in a reclassification of the Common Stock, then the number of
Warrant Shares purchasable upon exercise of this Warrant immediately prior
thereto shall be adjusted so that the Holder shall be entitled to receive the
kind and number of Warrant Shares or other securities of the Company which it
would have owned or have been entitled to receive had such Warrant been
exercised in advance thereof. Upon each such adjustment of the kind and number
of Warrant Shares or other securities of the Company which are purchasable
hereunder, the Holder shall thereafter be entitled to purchase the number of
Warrant Shares or other securities resulting from such adjustment at an Exercise
Price per Warrant Share or other security obtained by multiplying the Exercise
Price in effect immediately prior to such adjustment by the number of Warrant
Shares purchasable pursuant hereto immediately prior to such adjustment and
dividing by the number of Warrant Shares or other securities of the Company
resulting from such adjustment. An adjustment made pursuant to this paragraph
shall become effective immediately after the effective date of such event
retroactive to the record date, if any, for such event.

            12. Reorganization, Reclassification, Merger, Consolidation or
Disposition of Assets. In case the Company shall reorganize its capital,
reclassify its capital stock, consolidate or merge with or into another
corporation (where the Company is not the surviving corporation or where there
is a change in or distribution with respect to the Common Stock of the Company),
or sell, transfer or otherwise dispose of all or substantially all its property,
assets or business to another corporation and, pursuant to the terms of such
reorganization, reclassification, merger, consolidation or disposition of
assets, shares of common stock of the successor or acquiring corporation, or any
cash, shares of stock or other securities or property of any nature whatsoever
(including warrants or other subscription or purchase rights) in addition to or
in lieu of common stock of the successor or acquiring corporation ("Other
Property"), are to be received by or distributed to the holders of Common Stock
of the Company, then the Holder shall have the right thereafter to receive upon
exercise of this Warrant, the number of shares of Common Stock of the successor
or acquiring corporation or of the Company, if it is the surviving corporation,
and Other Property receivable upon or as a result of such reorganization,
reclassification, merger, consolidation or disposition of assets by a Holder of
the number of shares of Common Stock for which this Warrant is exercisable
immediately prior to such event. In case of any such reorganization,
reclassification, merger, consolidation or disposition of assets, the successor
or acquiring corporation (if other than the Company) shall expressly assume the
due and punctual observance and performance of each and every covenant and
condition of this Warrant to be performed and observed by the Company and all
the obligations and liabilities hereunder, subject to such modifications as may
be deemed appropriate (as determined in good faith by resolution of the Board of
Directors of the Company) in order to provide for adjustments of Warrant Shares
for which this Warrant is exercisable which shall be as nearly equivalent as
practicable to the adjustments provided for in this Section 12. For purposes of
this Section 12, "common stock of the successor or acquiring corporation" shall
include stock of such corporation of any class which is not preferred as to
dividends or assets over any other class of stock of such corporation and which
is not subject to redemption and shall also include any evidences of
indebtedness, shares of stock or other securities which are convertible into or
exchangeable for any such stock, either


                                       6


immediately or upon the arrival of a specified date or the happening of a
specified event and any warrants or other rights to subscribe for or purchase
any such stock. The foregoing provisions of this Section 12 shall similarly
apply to successive reorganizations, reclassifications, mergers, consolidations
or disposition of assets.

            13. Voluntary Adjustment by the Company. The Company may at any time
during the term of this Warrant reduce the then current Exercise Price to any
amount and for any period of time deemed appropriate by the Board of Directors
of the Company.

            14. Notice of Adjustment. Whenever the number of Warrant Shares or
number or kind of securities or other property purchasable upon the exercise of
this Warrant or the Exercise Price is adjusted, as herein provided, the Company
shall give notice thereof to the Holder, which notice shall state the number of
Warrant Shares (and other securities or property) purchasable upon the exercise
of this Warrant and the Exercise Price of such Warrant Shares (and other
securities or property) after such adjustment, setting forth a brief statement
of the facts requiring such adjustment and setting forth the computation by
which such adjustment was made.

            15. Notice of Corporate Action. If at any time:

                  (a) the Company shall take a record of the holders of its
      Common Stock for the purpose of entitling them to receive a dividend or
      other distribution, or any right to subscribe for or purchase any
      evidences of its indebtedness, any shares of stock of any class or any
      other securities or property, or to receive any other right, or

                  (b) there shall be any capital reorganization of the Company,
      any reclassification or recapitalization of the capital stock of the
      Company or any consolidation or merger of the Company with, or any sale,
      transfer or other disposition of all or substantially all the property,
      assets or business of the Company to, another corporation or,

                  (c) there shall be a voluntary or involuntary dissolution,
      liquidation or winding up of the Company;

then, in any one or more of such cases, the Company shall give to Holder (i) at
least 20 days' prior written notice of the date on which a record date shall be
selected for such dividend, distribution or right or for determining rights to
vote in respect of any such reorganization, reclassification, merger,
consolidation, sale, transfer, disposition, liquidation or winding up, and (ii)
in the case of any such reorganization, reclassification, merger, consolidation,
sale, transfer, disposition, dissolution, liquidation or winding up, at least 20
days' prior written notice of the date when the same shall take place. Such
notice in accordance with the foregoing clause also shall specify (i) the date
on which any such record is to be taken for the purpose of such dividend,
distribution or right, the date on which the holders of Common Stock shall be
entitled to any such dividend, distribution or right, and the amount and
character thereof, and (ii) the date on which any such reorganization,
reclassification, merger, consolidation, sale, transfer, disposition,
dissolution, liquidation or winding up is to take place and the time, if any
such time is to be fixed, as of which the holders of Common Stock shall be
entitled to exchange their Warrant Shares for securities or other property
deliverable upon such


                                       7


disposition, dissolution, liquidation or winding up. Each such written notice
shall be sufficiently given if addressed to Holder at the last address of Holder
appearing on the books of the Company and delivered in accordance with Section
17(d).

            16. Authorized Shares. The Company covenants that during the period
the Warrant is outstanding, it will reserve from its authorized and unissued
Common Stock a sufficient number of shares to provide for the issuance of the
Warrant Shares upon the exercise of any purchase rights under this Warrant. The
Company further covenants that its issuance of this Warrant shall constitute
full authority to its officers who are charged with the duty of executing stock
certificates to execute and issue the necessary certificates for the Warrant
Shares upon the exercise of the purchase rights under this Warrant. The Company
will take all such reasonable action as may be necessary to assure that such
Warrant Shares may be issued as provided herein without violation of any
applicable law or regulation, or of any requirements of the Trading Market upon
which the Common Stock may be listed.

                  Except and to the extent as waived or consented to by the
Holder, the Company shall not by any action, including, without limitation,
amending its certificate of incorporation or through any reorganization,
transfer of assets, consolidation, merger, dissolution, issue or sale of
securities or any other voluntary 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 Holder
as set forth in this Warrant against impairment. Without limiting the generality
of the foregoing, the Company will (a) not increase the par value of any Warrant
Shares above the amount payable therefor upon such exercise immediately prior to
such increase in par value, (b) take all such action as may be necessary or
appropriate in order that the Company may validly and legally issue fully paid
and nonassessable Warrant Shares upon the exercise of this Warrant, and (c) use
commercially reasonable efforts to obtain all such authorizations, exemptions or
consents from any public regulatory body having jurisdiction thereof as may be
necessary to enable the Company to perform its obligations under this Warrant.

                  Before taking any action which would result in an adjustment
in the number of Warrant Shares for which this Warrant is exercisable or in the
Exercise Price, the Company shall obtain all such authorizations or exemptions
thereof, or consents thereto, as may be necessary from any public regulatory
body or bodies having jurisdiction thereof.

            17. Miscellaneous.

            (a) Jurisdiction. This Warrant shall constitute a contract under the
      laws of New York, without regard to its conflict of law, principles or
      rules.

            (b) Restrictions. The Holder acknowledges that the Warrant Shares
      acquired upon the exercise of this Warrant, if not registered, will have
      restrictions upon resale imposed by state and federal securities laws.


                                       8


            (c) Nonwaiver. No course of dealing or any delay or failure to
      exercise any right hereunder on the part of Holder shall operate as a
      waiver of such right or otherwise prejudice Holder's rights, powers or
      remedies, notwithstanding all rights hereunder terminate on the
      Termination Date.

            (d) Notices. Any notice, request or other document required or
      permitted to be given or delivered to the Holder by the Company shall be
      delivered in accordance with the notice provisions of the Purchase
      Agreement.

            (e) Successors and Assigns. Subject to applicable securities laws,
      this Warrant and the rights and obligations evidenced hereby shall inure
      to the benefit of and be binding upon the successors of the Company and
      the successors and permitted assigns of Holder. The provisions of this
      Warrant are intended to be for the benefit of all Holders from time to
      time of this Warrant and shall be enforceable by any such Holder or holder
      of Warrant Shares.

            (f) Limitation of Liability. No provision hereof, in the absence of
      any affirmative action by Holder to exercise this Warrant or purchase
      Warrant Shares, and no enumeration herein of the rights or privileges of
      Holder, shall give rise to any liability of Holder for the purchase price
      of any Common Stock or as a stockholder of the Company, whether such
      liability is asserted by the Company or by creditors of the Company.

            (g) Remedies. Holder, in addition to being entitled to exercise all
      rights granted by law, including recovery of damages, will be entitled to
      specific performance of its rights under this Warrant. The Company agrees
      that monetary damages would not be adequate compensation for any loss
      incurred by reason of a breach by it of the provisions of this Warrant and
      hereby agrees to waive the defense in any action for specific performance
      that a remedy at law would be adequate.

            (h) Amendment. This Warrant may be modified or amended or the
      provisions hereof waived with the written consent of the Company and the
      Holder.

            (i) Severability. Wherever possible, each provision of this Warrant
      shall be interpreted in such manner as to be effective and valid under
      applicable law, but if any provision of this Warrant shall be prohibited
      by or invalid under applicable law, such provision shall be ineffective to
      the extent of such prohibition or invalidity, without invalidating the
      remainder of such provisions or the remaining provisions of this Warrant.

            (j) Headings. The headings used in this Warrant are for the
      convenience of reference only and shall not, for any purpose, be deemed a
