                To Purchase __________ Shares of Common Stock of

                       Synthetic Blood International, Inc.

         THIS COMMON STOCK PURCHASE WARRANT (the "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 the date of the Registration Agreement (the "Initial
Exercise Date") and on or prior to the earlier of (a) the 90th day from and
including the Effective Date and (b) May 31, 2005 (the "Termination Date") but
not thereafter, to subscribe for and purchase from Synthetic Blood
International, Inc., a New Jersey corporation (the "Company"), up to
____________ shares (the "Warrant Shares") of Common Stock, par value $0.01 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 $0.60, 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 Registration Rights Agreement (the
"Registration Agreement"), dated May 13, 2004 among the Company and the
purchasers signatory thereto.

         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.

                                       1
<PAGE>

         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) 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 delivery to the Company of a duly executed facsimile
copy of the Notice of Exercise Form annexed hereto (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);
provided, however, said exercise will be void and of no effect if the Holder
does not surrender this Warrant to the Company and the Company does not receive
payment of the aggregate Exercise Price of the shares purchased by wire transfer
or cashier's check drawn on a United States bank on or before the fifth day on
which the Common Stock is listed or quoted for trading on the Nasdaq SmallCap
Market, the American Stock Exchange, the New York Stock Exchange, the Nasdaq
National Market or the OTC Bulletin Board (each a "Trading Day") from the date
Notice of Exercise is delivered to the Company. Certificates for shares
purchased hereunder shall be delivered to the Holder within 3 Trading Days from
the delivery to the Company of the Notice of Exercise Form, surrender of this
Warrant and payment of the aggregate Exercise Price as set forth above ("Warrant
Share Delivery Date"). This Warrant shall be deemed to have been exercised on
the date the Exercise Price is received by the Company. The Warrant Shares 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 Warrant Share Delivery Date, then the Holder will have the
right to rescind such exercise. In addition to any other rights available to the
Holder, if the Company fails to deliver to the Holder a certificate or
certificates representing the Warrant Shares pursuant to an exercise by the
Warrant Share Delivery Date, and if after such day 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 Shares
which the Holder anticipated receiving upon such exercise (a "Buy-In"), then the
Company 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 Warrant Shares that the Company 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 Warrant Shares 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 Company timely complied with its exercise and delivery obligations
hereunder.

                                       2
<PAGE>

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 Company shall be required to pay the Holder $1,000. The Holder shall provide
the Company 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 Company. 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 Company's failure to timely deliver
certificates representing shares of Common Stock upon exercise of the Warrant as
required pursuant to the terms hereof.

         (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 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) The Holder shall not have the right to exercise any portion of this
Warrant, pursuant to Section 3(a) or otherwise, to the extent that after giving
effect to such issuance after exercise, the Holder (together with the Holder's
affiliates), as set forth on the applicable Notice of Exercise, would
beneficially own in excess of 9.99% of the number of shares of the Common Stock
outstanding immediately after giving effect to such issuance. For purposes of
the foregoing sentence, the number of shares of Common Stock beneficially owned
by the Holder and its affiliates shall include the number of shares of Common
Stock issuable upon exercise of this Warrant with respect to which the
determination of such sentence is being made, but shall exclude the number of
shares of Common Stock which would be issuable upon (A) exercise of the
remaining, nonexercised portion of this Warrant beneficially owned by the Holder
or any of its affiliates and (B) exercise or conversion of the unexercised or
nonconverted portion of any other securities of the Company (including, without
limitation, any other Warrants) subject to a limitation on conversion or
exercise analogous to the limitation contained herein beneficially owned by the
Holder or any of its affiliates. Except as set forth in the preceding sentence,
for purposes of this Section 3(c), beneficial ownership shall be calculated in
accordance with Section 13(d) of the Exchange Act, it being acknowledged by
Holder that the Company is not representing to Holder that such calculation is
in compliance with Section 13(d) of the Exchange Act and Holder is solely
responsible for any schedules required to be filed in accordance therewith. 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. For purposes
of this Section 3(c), in determining the number of outstanding shares of Common
Stock, the Holder may rely on the number of outstanding shares of Common Stock
as reflected in (x) the Company's most recent Form 10-Q or Form 10-K, as the
case may be, (y) a more recent public announcement by the Company or (z) any
other notice by the Company or the Company's Transfer Agent setting forth the
number of shares of

                                       3
<PAGE>

Common Stock outstanding. Upon the written or oral request of the Holder, the
Company shall within two Trading Days confirm orally and in writing to the
Holder the number of shares of Common Stock then outstanding. In any case, the
number of outstanding shares of Common Stock shall be determined after giving
effect to the conversion or exercise of securities of the Company, including
this Warrant, by the Holder or its affiliates since the date as of which such
number of outstanding shares of Common Stock was reported.

         4. No Fractional Shares or Scrip. No fractional shares or scrip
representing 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(e) hereof and to the provisions of
Section 4.1 of the Registration 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 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

                                       4
<PAGE>

or Warrants in exchange for the Warrant or Warrants to be divided or combined in
accordance with such notice.

         (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)(1), (a)(2), (a)(3), (a)(7), or
(a)(8) promulgated under the Securities Act or a qualified institutional buyer
as defined in Rule 144A(a) 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.

                                       5

         11. Adjustments of Exercise Price and Number of Warrant Shares.

         (a) 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 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 that
are purchasable pursuant hereto immediately after 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.

         (b) Minimum Adjustment of Exercise Price. No adjustment of the Exercise
Price shall be made in an amount of less than 1% of the Exercise Price in effect
at the time such adjustment is otherwise required to be made, but any such
lesser adjustment shall be carried forward and shall be made at the time and
together with the next subsequent adjustment which, together with any
adjustments so carried forward, shall amount to not less than 1% of such
Exercise Price.

         (c) 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 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,

                                       6
<PAGE>

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 11. For purposes of
this Section 11, "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 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 11(c) shall similarly apply to successive reorganizations,
reclassifications, mergers, consolidations or disposition of assets.

         (d) 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.

         (e) 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. Notice of Corporate Action. If at any time:

                  (i) 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

                  (ii) 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,

                  (iii) 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,

                                       7
<PAGE>

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 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).

         12. 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.

                                       8
<PAGE>

         13. Miscellaneous.

         (a) Jurisdiction. All questions concerning the construction, validity,
enforcement and interpretation of this Warrant shall be governed by and
construed and enforced in accordance with the internal laws of the State of
Delaware, without regard to the principles of conflicts of law thereof.

         (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.

         (c) Nonwaiver and Expenses. 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. If the
Company willfully and knowingly fails to comply with any provision of this
Warrant, which results in any material damages to the Holder, the Company shall
pay to Holder such amounts as shall be sufficient to cover any costs and
expenses including, but not limited to, reasonable attorneys' fees, including
those of appellate proceedings, incurred by Holder in collecting any amounts due
pursuant hereto or in otherwise enforcing any of its rights, powers or remedies
hereunder.

         (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 Registration
Agreement.

         (e) 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.

         (f) 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.

         (g) 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.

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

                                       9
<PAGE>

         (h) 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.

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

                  N WITNESS WHEREOF, the Company has caused this Warrant to be
