                   WARRANT TO PURCHASE SHARES OF COMMON STOCK
                   ------------------------------------------

         THIS CERTIFIES that, for value received, KIRLIN SECURITIES, INC. (such
person or entity and any successor and assign being hereinafter referred to as
the `Holder") is entitled to subscribe for and purchase from GENDER SCIENCES,
INC., a New Jersey corporation (hereinafter called the "Company"), Fifty
Thousand (50,000) shares of Common Stock, (the "Common Stock"), of the Company
(such shares to be subject to adjustment in accordance with Section 4 hereof,
hereinafter sometimes called the "Shares") at an exercise price of Three Dollars
($3.00) per share as adjusted in accordance with Section 4 hereof (the "Exercise
Price'), at any time or from time to time from the date hereof to and including
April 1, 2008 (the "Exercise Period").

         1.       Exercise.
                  --------

                  (i)      While this Warrant remains outstanding and
exercisable in accordance with the terms hereof, the Holder may exercise, in
whole or in part, the purchase rights evidenced hereby. Such exercise shall be
effected by:

                           (a)      the surrender of the Warrant, together with
                  a duly executed copy of the Notice of Exercise attached
                  hereto, to the Secretary of the Company at its principal
                  office (or at such other place as the Company shall notify the
                  Holder in writing); and

                           (b)      the payment to the Company of an amount
                  equal to the aggregate Exercise Price for the number of Shares
                  being purchased.

                  (ii)     Each exercise of this Warrant shall be deemed to have
been effected immediately prior to the close of business on the day on which
this Warrant shall have been surrendered to the Company as provided in Section
1(i) above. At such time, the person or persons in whose name or names any
certificates for the Shares shall be issuable upon such exercise as provided in
Section 1(iii) below shall be deemed to have become the holder or holders of
record of the Shares represented by such certificates.

                                       1
<PAGE>

                  (iii)    As soon as practicable after the exercise of this
Warrant in whole or in part, and in any event within twenty (20) days
thereafter, the Company at its expense will cause to be issued in the name of,
and delivered to, the Holder, or as such Holder (upon payment by such Holder of
any applicable transfer taxes) may direct:

                           (a)      a certificate or certificates for the number
                  of Shares to which such Holder shall be entitled, and

                           (b)      in case such exercise is in part only, a new
                  warrant or warrants (dated the date hereof) of like tenor,
                  calling in the aggregate on the face or faces thereof for the
                  number of Shares equal (without giving effect to any
                  adjustment therein) to the number of such Shares called for on
                  the face of this Warrant minus the number of such Shares
                  purchased by the Holder upon such exercise as provided in
                  Section 1(i) above.

         2.       Covenants of the Company.
                  ------------------------

                  (i)      Notice of Record Date. In the event of any taking by
the Company of a record of the holder(s) of Common Stock for the purpose of
determining the holders thereof who are entitled to receive any dividend (other
than a case dividend which is the same as cash dividends paid in previous
quarters) or other distribution, the Company shall mail to the Holder, at least
ten (10) days prior to the date specified herein, a notice specifying the date
on which any such record is to be taken for the purpose of such dividend or
distribution.

                  (ii)     Covenants as to Exercise Shares. The Company
covenants and agrees that all Shares that may be issued upon the exercise of the
rights represented by this Warrant will, upon issuance, be validly issued and
outstanding, fully paid and nonassessable, and free from all taxes, liens and
charges with respect to the issuance thereof. The Company further covenants and
agrees that the Company will at all times during the Exercise Period, have
authorized and reserved, free from preemptive rights, a sufficient number of
shares of its Common Stock to provide for the exercise of the rights represented
by this Warrant. If at any time during the Exercise Period the number of
authorized but unissued shares of Common Stock shall not be sufficient to permit
exercise of this Warrant, the Company will take such corporate action as may, in
the opinion of its counsel, be necessary to increase its authorized but unissued
shares of Common Stock to such number of shares as shall be sufficient for such
purposes.

                  (iii)    No Impairment. Except and to the extent as waived or
consented to by the Holder, the Company will not, by amendment of 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 to be observed or performed hereunder by the Company, but will at
times in good faith assist in the carrying out of all the provisions of this
Warrant and in the taking of all such action as may be necessary or appropriate
in order to protect the exercise rights of the Holder against impairment.

                                       2
<PAGE>

         3.       Adjustment of Exercise Price and Number of Shares. The number
of and kind of securities purchasable upon exercise of this Warrant and the
Exercise Price shall be subject to adjustment from time to time as follows:

                  (i)      Subdivisions, Combinations and Other Issuances. If
the Company shall at any time prior to the expiration of this Warrant subdivide
its Common Stock, by split-up or otherwise, or combine its Common Stock, or
issue additional shares of its Common Stock as a dividend with respect to any
shares of its Common Stock, the number of Shares issuable on the exercise of
this Warrant shall forthwith be proportionately increased in the case of a
subdivision or stock dividend, or proportionately decreased in the case of a
combination. Appropriate adjustments shall also be made to the Exercise Price
payable per share, but the aggregate Exercise Price payable for the total number
of Shares purchasable under this Warrant (as adjusted) shall remain the same.
Any adjustment under this Section 4(i) shall become effective at the close of
business on the date the subdivision or combination becomes effective, or as of
the record date of such dividend, or in the event that no record date is fixed,
upon the making of such dividend.

                  (ii)     Reclassification and Consolidation. In the case of
any reclassification or change in the Shares of the Company (other than as a
result of a subdivision, combination, or stock dividend provided for in Section
4(i) above), then, as a condition of such reclassification or change, lawful
provision shall be made, and duly executed documents evidencing the same from
the Company or its successor shall be delivered to the Holder, so that the
Holder shall have the right at any time prior to the expiration of this Warrant
to purchase, at a total price equal to that payable upon the exercise of this
Warrant, the kind and amount of shares of stock and other securities and
property receivable in connection with such reclassification or change by a
holder of the same number of Shares as were purchasable by the Holder
immediately prior to such reclassification or change. In any such case
appropriate provisions shall be made with respect to the rights and interest of
the Holder so that the provisions hereof shall thereafter be applicable with
respect to any shares or other securities and property deliverable upon exercise
hereof, and appropriate adjustments shall be made to the Exercise Price per
Share payable hereunder, provided the aggregate Exercise Price shall remain the
same.

                  (iii)    Adjustment for Reorganization, Merger. In case of any
reorganization of the Company (or any other corporation, the securities of which
are at the time receivable on the exercise of this Warrant) after the date
hereof, or in case after such date the Company (or any such other corporation)
shall consolidate with or merge into another corporation or convey all or
substantially all of its assets to another corporation, then, and in each such
case, the Holder of this Warrant upon the exercise as provided in Section 1
above at any time after the consummation of such reorganization, consolidation,
merger or conveyance, shall be entitled to receive, in lieu of the securities
and property receivable upon the exercise of this Warrant prior to such
consummation, the securities or property to which such Holder would have been
entitled upon such consummation if such Holder had exercised this Warrant
immediately prior thereto; in each such case, the terms of this Warrant shall be
applicable to the securities or property received upon the exercise of this
Warrant after such consummation.

                  (iv)     Notice of Adjustment. When any adjustment is required
to be made in the number or kind of shares purchasable upon exercise of the
Warrant, or in the Warrant Price, the Company shall promptly notify the Holder
of such event and of the number of Shares or other securities or property
thereafter purchasable upon exercise of this Warrant.

                                       3
<PAGE>

         4.       Investment Representations; Indemnification. The Holder agrees
and acknowledges the Warrant is being acquired for its own account, for
investment purposes only, that it either has a prior personal or business
relationship with the officers, directors or controlling persons, or by reason
of its business or financial experience, or the business or financial experience
of its professional advisors who are unaffiliated with and not compensated by
the Company, could be reasonably assumed to have the capacity to protect its own
interests in connection with the Warrant. Holder further represents, warrants
and agrees that Holder will not sell, hypothecate or otherwise transfer this
Warrant except in accordance with the Securities Act of 1933, as amended (the
"Securities Act"), applicable state securities laws and the terms hereof. The
Holder hereby agrees to indemnify and hold harmless the Company, its
representatives and each officer, director, agent, and legal counsel thereof
from and against any and all loss, damage or liability (including all attorneys'
fees and costs incurred in enforcing this indemnity provision) due to or arising
out of (a) the inaccuracy of any representation or the breach of any warranty of
the Holder contained in, or any other breach of, this Warrant, (b) any transfer
of any of this Warrant or the Shares in violation of the Securities Act, the
Securities Exchange Act of 1934, as amended, or the rules and regulations
promulgated under either of such acts, (c) any transfer of this Warrant or any
of the Shares not in accordance with this Warrant or (d) any untrue statement or
omission to state any material fact in connection with the investment
representations.

         5.       Registration Rights. Holder shall execute a counterpart
signature page to the Company's Amended and Restated Registration Rights
Agreement. Pursuant to such agreement Holder shall, with respect to the Shares,
be entitled to unlimited piggyback registration rights on registrations of the
Company, subject to the right of any underwriter retained by the Company to
limit the number of shares covered by any such registration.

         6.       No Fractional Shares or Scrip. The Company shall not be
required to issue stock certificates representing fractions of shares of Common
Stock, nor shall it be required to issue script or pay cash in lieu of
fractional interests, it being the intent of the parties that all fractional
interests shall be eliminated.

         7.       No Shareholder Rights. Prior to exercise of this Warrant, the
Holder shall not be entitled to any rights of a shareholder with respect to the
Shares, including (without limitation) the right to vote such Shares, receive
dividends or other distributions thereon, exercise preemptive rights or be
notified of stockholder meetings, and such Holder shall not be entitled to any
shareholder notice or other communication concerning the business or affairs of
the Company.

         8.       Transfer of Warrant. Subject to compliance with applicable
federal and state securities laws, this Warrant and all rights hereunder are
transferable in whole or in part by the Holder to any person or entity upon
written notice to the Company. Within a reasonable time after the Company's
receipt of an executed Assignment Form in the form attached hereto, the transfer
shall be recorded on the books and be reflected on the capitalization table of

                                       4
<PAGE>

the Company upon the surrender of this Warrant, properly endorsed, to the
Company at its principal offices, and the payment to the Company of all transfer
taxes and other governmental changes imposed on such transfer. In the event of a
partial transfer, the Company shall issue to the new holders one or more
appropriate new warrants.

         9.       Successors and Assigns. The terms and provisions of this
Warrant shall inure to the benefit of, and be binding upon, the Company and the
holder hereof and their respective successors and assigns.

         10.      Notices. All notices under this Warrant shall be in writing
and shall be deemed to have been given (a) upon receipt, when delivered by hand
or by electronic facsimile transmission, or (b) upon actual delivery by
overnight courier, or (c) three days after mailing by regular first-class mail
or certified mail return receipt requested, addressed to each party at the
addresses indicated below their signatures below or at such other address as
such party may designate by ten (10) business days' advance written notice to
the other party.

         11.      Amendments and Waivers. This Warrant may be amended, and the
observance of any term hereof may be waived, pursuant to a written agreement
executed by the parties hereto.

         12.      Governing Law. This Warrant and all acts and transactions
hereunder and all rights and obligations of Holder and Company shall be governed
by the internal laws (and not the conflict of laws rules) of the State of
Delaware.

         13.      General. Should any provision of this Warrant be held by any
court of competent jurisdiction to be void or unenforceable, such defect shall
not affect the remainder of this Warrant, which shall continue in full force and
effect. This Warrant and such other written agreements, documents and
instruments as may be executed in connection herewith are the final, entire and
complete agreement between Company and Holder and supersede all prior and
contemporaneous negotiations and oral representations and agreements, all of
which are merged and integrated in this Warrant. There are no oral
understandings, representations or agreements between the parties which are not
set forth in this Warrant or in other written agreements signed by the parties
in connection herewith. This Warrant may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which shall
constitute one agreement. Each of the counterparts may be signed and transmitted
by facsimile with the same validity as if it were an original document, provided
the original thereof thereafter is delivered.

                                       5

         IN WITNESS WHEREOF, the Company has caused this Warrant to be executed
by a duly authorized officer and to be dated as of the date first above written.

April 22, 2003                                     11,625 Shares of Common Stock

                         Not Transferable or Exercisable
                     Except Upon Conditions Herein Specified
                     ---------------------------------------

     THIS CERTIFIES that, for value received, Unity Venture Capital Associates
Ltd. (such person or entity and any successor and assign being hereinafter
referred to as the `Holder") is entitled to subscribe for and purchase from
MEDICAL NUTRITION USA, INC., a Delaware corporation (hereinafter referred to as
the "Company"), Eleven thousand, six hundred and twenty five (11,625) shares of
Common Stock, (the "Common Stock"), of the Company (such shares to be subject to
adjustment in accordance with Sections 1 and 5 hereof, hereinafter sometimes
called the "Warrant Shares") at an exercise price of Two dollars and fifty cents
($2.50) per share as adjusted in accordance with Section 1 hereof (the "Strike
Price').

     1. Exercise of Warrant.

          1.1 The rights represented by this Warrant may be exercised by the
Holder hereof, in whole at any time or in part from time to time from and after
the date hereof to and including April 22, 2006 (the "Exercise Period"), but not
as to a fractional share of Common Stock, by the surrender of this Warrant
(properly endorsed) at the principal office of the Company, at 10 West Forest
Avenue, Englewood, New Jersey 07631 (or at such other agency or office of the
Company in the United States of America as the Company may designate by notice
in writing to the Holder hereof at the address of such Holder appearing on the
books of the Company), and by payment to the Company of the Strike Price in cash
or by certified or official bank check in United States Dollars for each share
being purchased (the "Exercise Payment"). Notwithstanding the foregoing, this
Warrant must be exercised in whole by the holder hereof within forty-five (45)
days of receipt of written notice from the Company (the "Exercise Notice")
setting forth the following: (a) at least one (1) year has passed from the date
of issuance of this Warrant, and (b) within the thirty (30) days preceding the
date of the Exercise Notice the Company's common stock has traded for ten (10)
consecutive trading days at a price per share of $4.00 or more (subject to
equitable adjustment in the case of stock splits, combinations or similar
<PAGE>

events). This Warrant shall be void with respect to any Warrant Shares not
purchased on or before the expiration of such forty-five (45) day period.

          1.2 In the event of any exercise of the rights represented by this
Warrant, (i) a certificate or certificates for the shares of Common Stock so
purchased, registered in the name of the person entitled to receive the same,
shall be mailed to the Holder as soon as practicable (but in any event within
ten (10) days) after the rights represented by this Warrant shall have been so
exercised; provided, however, that the Company shall not be required to pay any
tax which may be payable in respect of any transfer involved in the issuance and
delivery of any such certificate in a name other than that of the registered
Holder thereof, and the Company 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 Company the amount of such tax or shall have
established to the satisfaction of the Company that such tax has been paid; and
(ii) unless this Warrant has expired, a new Warrant representing the number of
shares (except a remaining fractional share), if any, with respect to which this
Warrant shall not then have been exercised shall also be issued to the Holder
hereof within such time. The person in whose name any certificate for shares of
Common Stock is issued upon exercise of this Warrant shall, for all purposes, be
deemed to have become the Holder of record of such shares on the date on which
this Warrant was surrendered and payment of the Strike Price was made,
irrespective of the date of delivery of such certificate, except that, if the
date of such surrender and payment is a date when the stock transfer books of
the Company are closed, such person shall be deemed to have become the Holder of
record of such shares at the close of business on the next succeeding date on
which the stock transfer books are open. The issuance of any shares of Common
Stock pursuant to the terms of this Warrant shall at all times be subject to
compliance with all requirements of the Securities Act of 1933, as amended (the
"Securities Act"), and with all applicable foreign and state securities and blue
sky laws then in effect.

          1.3 Covenants as to Capital Stock. The Company covenants and agrees
all Warrant Shares will, upon issuance, be validly issued, fully paid and
nonassessable, and free from all taxes, liens and charges with respect to the
issue thereof. If and so long as the Common Stock issuable upon the exercise of
this Warrant is listed on any national securities exchange or quoted on any
quotation system, the Company will, if permitted by the rules of such exchange
or system, list and keep listed or quoted on such exchange or quotation system,
upon official notice of issuance, all of the Warrant Shares. The Company shall
keep reserved a sufficient number of shares of the authorized and unissued
shares of Common Stock, to provide for the exercise of the rights of purchase
represented by this Warrant in compliance with its terms.

     2. Transfer.

          2.1 Securities Laws. Neither this Warrant nor the Warrant Shares have
been registered under the Securities Act. The Company will not transfer this
Warrant or the Warrant Shares unless (i) there is an effective registration

          2.2 Investment Representations. The Holder of the Warrant agrees and
acknowledges the Warrant is being purchased for his, her or its own account, for
investment purposes only, that he, she or it either has a prior personal or
business relationship with the officers, directors or controlling persons, or by
reason of his business or financial experience, or the business or financial
experience of his, her or its professional advisors who are unaffiliated with
and not compensated by the Company, could be reasonably assumed to have the
capacity to protect his, her or its own interests in connection with the
purchase of and the exercise of the Warrant, and not for the account of any
other person, and not with a view to distribution, assignment or resale to
others or to fractionalization in whole or in part, and the Holder further
represents, warrants and agrees as follows: no other person has or will have a
direct or indirect beneficial interest in this Warrant and the Holder will not
sell, hypothecate or otherwise transfer the Warrant except in accordance with
the Securities Act and applicable state securities laws or unless, in the
opinion of counsel for the Holder acceptable to the Company, an exemption from
the registration requirements of the Securities Act and such state laws is
available.

          2.3 Conditions to Transfer. Prior to any such proposed transfer, and
as a condition thereto, if such transfer is not made pursuant to an effective
registration statement under the Securities Act, the Holder will, if requested
by the Company, deliver to the Company (i) an investment covenant signed by the
proposed transferee, (ii) an agreement by such transferee that the restrictive
investment legend set forth below be placed on the certificate or certificates
representing the securities acquired by such transferee, (iii) an agreement by
such transferee that the Company may place a "stop transfer order" with its
transfer agent or registrar, and (iv) an agreement by the transferee to
indemnify the Company to the same extent as set forth in the next succeeding
paragraph.

          2.4 Indemnity. The Holder acknowledges the Holder understands the
meaning and legal consequences of this Section, and the Holder hereby agrees to
indemnify and hold harmless the Company, its representatives and each officer,
director, agent, and legal counsel thereof from and against any and all loss,
damage or liability (including all attorneys' fees and costs incurred in
enforcing this indemnity provision) due to or arising out of (a) the inaccuracy
of any representation or the breach of any warranty of the Holder contained in,
or any other breach of, this Warrant, (b) any transfer of any of this Warrant or
the Warrant Shares in violation of the Securities Act, the Securities Exchange
Act of 1934, as amended, or the rules and regulations promulgated under either
of such acts, (c) any transfer of this Warrant or any of the Warrant Shares not
in accordance with this Warrant or (d) any untrue statement or omission to state
any material fact in connection with the investment representations or with
respect to the facts and representations supplied by the Holder to counsel to
the Company upon which its opinion as to a proposed transfer shall have been
based.

          2.5 Transfer. Except as specifically restricted hereby, this Warrant
and the Warrant Shares issued may be transferred by the Holder in whole or in
part at any time or from time to time. Upon surrender of this Warrant
certificate to the Company or at the office of its stock transfer agent, if any,
with the Assignment Form annexed hereto duly executed and funds sufficient to
pay any transfer tax, and upon compliance with the foregoing provisions, the
Company shall, without charge, execute and deliver a new Warrant certificate in
the name of the assignee named in such instrument of assignment, and this
Warrant certificate shall promptly be canceled. Any assignment, transfer,
pledge, hypothecation or other disposition of this Warrant

                                      -3-
<PAGE>

attempted contrary to the provisions of this Warrant, or any levy of execution,
attachment or other process attempted upon this Warrant, shall be null and void
and without effect.

     3. Rights of the Holder. The Holder shall not, by virtue hereof, be
entitled to any rights of a shareholder in the Company, either at law or in
equity, and the rights of the Holder are limited to those expressed in this
Warrant.

     4. Anti-Dilution Provisions.

          4.1 Stock Splits, Dividends, Etc.

               4.1.1 If the Company shall at any time after the date hereof
subdivide its outstanding shares of Common Stock (or other securities at the
time receivable upon the exercise of the Warrant) by recapitalization,
reclassification or split-up thereof, or if the Company shall declare a stock
dividend or distribute shares of Common Stock to its shareholders, the number of
shares of Common Stock subject to this Warrant immediately prior to such
subdivision shall be proportionately increased, and if the Company shall at any
time combine the outstanding shares of Common Stock by recapitalization,
reclassification or combination thereof, the number of shares of Common Stock
subject to this Warrant immediately prior to such combination shall be
proportionately decreased.

               4.1.2 Whenever the number of shares of Common Stock purchasable
upon the exercise of this Warrant is adjusted, as provided in this Section, the
Strike Price shall be adjusted to the nearest cent by multiplying such Strike
Price immediately prior to such adjustment by a fraction (x) the numerator of
which shall be the number of shares of Common Stock purchasable upon the
exercise immediately prior to such adjustment, and (y) the denominator of which
shall be the number of shares of Common Stock so purchasable immediately
thereafter. Any such adjustment to the Strike Price pursuant to this Section
shall be effective at the close of business on the effective date of such
subdivision or combination or if any adjustment is the result of a stock
dividend or distribution then the effective date for such adjustment based
thereon shall be the record date therefor.

          4.2 Adjustment for Reorganization, Consolidation, Merger, Etc. In case
of any reorganization of the Company (or any other corporation, the securities
of which are at the time receivable on the exercise of this Warrant) after the
date hereof, or in case after such date the Company (or any such other
corporation) shall consolidate with or merge into another corporation or convey
all or substantially all of its assets to another corporation, then, and in each
such case, the Holder of this Warrant upon the exercise as provided in Section 1
above at any time after the consummation of such reorganization, consolidation,
merger or conveyance, shall be entitled to receive, in lieu of the securities
and property receivable upon the exercise of this Warrant prior to such
consummation, the securities or property to which such Holder would have been
entitled upon such consummation if such Holder had exercised this Warrant
immediately prior thereto; in each such case, the terms of this Warrant shall be
applicable to the securities or property received upon the exercise of this
Warrant after such consummation.

          4.3 Certificate as to Adjustments. In each case of an adjustment in
the number of shares of Common Stock receivable on the exercise of this Warrant,
the Company at its expense

                                      -4-
<PAGE>

shall promptly compute such adjustment in accordance with the terms of the
Warrant and prepare a certificate executed by an officer of the Company setting
forth such adjustment and showing the facts upon which such adjustment is based.
The Company shall forthwith mail a copy of each such certificate to each Holder.

          4.4 Notices of Record Date, Etc. In case:

               4.4.1 the Company shall take a record of the holders of its
Common Stock (or other securities at the time receivable upon the exercise of
the Warrant) for the purpose of entitling them to receive any dividend (other
than a cash dividend at the same rate as the rate of the last cash dividend
theretofore paid) or other distribution, or any right to subscribe for, purchase
or otherwise acquire any shares of stock of any class or any other securities,
or to receive any other right; or

               4.4.2 of any voluntary or involuntary dissolution, liquidation or
winding-up of the Company, then, and in each such case, the Company shall mail
or cause to be mailed to each Holder a notice specifying, as the case may be,
(A) the date on which a record is to be taken for the purpose of such dividend,
distribution or right, and stating the amount and character of such dividend,
distribution or right, or (B) the date on which such reorganization,
reclassification, consolidation, merger, conveyance, dissolution, liquidation or
winding-up is to take place, and the time, if any, to be fixed, as to which the
holders of record of Common Stock (or such other securities at the time
receivable upon the exercise of this Warrant) shall be entitled to exchange
their shares of Common Stock (or such other securities) for securities or other
property deliverable upon such reorganization, reclassification, consolidation,
merger, conveyance, dissolution, liquidation or winding-up. Such notice shall be
mailed at least twenty (20) days prior to the date therein specified, and this
Warrant may be exercised prior to said date during the term of the Warrant.

          4.5 Threshold for Adjustments. Anything in this Section to the
contrary notwithstanding, the Company shall not be required to give effect to
any adjustment until the cumulative resulting adjustment in the Strike Price
pursuant to this Section shall have required a change of the Strike Price by at
least $0.01. No adjustment shall be made by reason of the issuance of shares
upon conversion rights, stock issuance rights or similar rights currently
outstanding or any change in the number of treasury shares held by the Company.

     5. Legend and Stop Transfer Orders. Unless the Warrant Shares have been
registered under the Securities Act, upon exercise of any of this Warrant and
the issuance of any of the Warrant Shares, the Company shall instruct its
transfer agent, if any, to enter stop transfer orders with respect to such
shares, and all certificates representing shares of Warrant Shares shall bear on
the face thereof substantially the following legend:

          THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
          REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
          "ACT") OR ANY OTHER SECURITIES LAWS AND MAY NOT BE OFFERED
          FOR SALE, SOLD, DELIVERED AFTER SALE, TRANSFERRED, PLEDGED

                                      -5-
<PAGE>

          OR HYPOTHECATED IN THE ABSENCE OF (1) AN EFFECTIVE
          REGISTRATION STATEMENT COVERING THESE SECURITIES UNDER THE
          ACT AND ANY OTHER APPLICABLE SECURITIES LAWS, OR (2) AN
          OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE COMPANY
          THAT SUCH REGISTRATION IS NOT REQUIRED.

     6. Officer's Certificate. Whenever the number or kind of securities
purchasable upon exercise of this Warrant or the Strike Price shall be adjusted
as required by the provisions hereof, the Company shall forthwith file with its
Secretary or Assistant Secretary at its principal office and with its stock
transfer agent, if any, an officer's certificate showing the adjusted number
and/or kind of securities purchasable upon exercise of this Warrant and the
adjusted Strike Price determined as herein provided and setting forth in
reasonable detail such facts as shall be necessary to show the reason for and
the manner of computing such adjustments. Each such officer's certificate shall
be made available at all reasonable times for inspection by the Holder and the
Company shall, forthwith after each such adjustment, mail by certified mail a
copy of such certificate to the Holder.

     7. Transfer of Warrant. Subject to Section 3 hereof, this Warrant and all
rights hereunder are transferable in whole (or in part), at the agency of office
or the Company referred to in Section 1 hereof by the Holder hereof in person or
by duly authorized attorney, upon surrender of this Warrant properly endorsed.
Each taker and Holder of this Warrant, by taking or holding the same, consents
and agrees that this Warrant, when endorsed, in blank, shall be deemed
negotiable, and, when so endorsed the Holder hereof may be treated by the
Company and all other persons dealing with this Warrant as the absolute owner
hereof for all purposes and as the person entitled to exercise the rights
represented by this Warrant, or to the transfer hereof on the books of the
Company, any notice to the contrary notwithstanding; but until each transfer on
such books, the Company may treat the registered Holder hereof as the owner
hereof for all purposes.

     8. Elimination of Fractional Interests. The Company shall not be required
to issue stock certificates representing fractions of shares of Common Stock,
nor shall it be required to issue script or pay cash in lieu of fractional
interests, it being the intent of the parties that all fractional interests
shall be eliminated.

     9. Exchange of Warrant. Subject to the limitations set forth herein this
Warrant is exchangeable, upon the surrender hereof by the Holder hereof at the
office or agency of the Company designated in Section 1 hereof, for a new
Warrant of like tenor representing the right to subscribe for and purchase the
number of Warrant Shares which may be subscribed for and purchased hereunder.

     10. Lost, Stolen, Mutilated or Destroyed Warrant. Upon surrender by the
Holder of this Warrant to the Company, the Company at its expense will issue in
exchange therefor, and deliver to such Holder, a new Warrant. Upon receipt of
evidence reasonably satisfactory to the Company of the loss, theft, destruction
or mutilation of this Warrant, and in the case of any such loss, theft or
destruction, upon delivery by such Holder of an indemnity agreement or security

                                      -6-
<PAGE>

reasonably satisfactory to the Company, and in case of any such mutilation, upon
surrender and cancellation of this Warrant, the Company, upon reimbursement of
all reasonable expenses incident thereto, will issue and deliver to such Holder
a new Warrant of like tenor, in lieu of such lost, stolen, destroyed or
mutilated Warrant. Any Warrant delivered to such Holder in accordance with this
Section 11 shall bear the same securities legends as the Warrant which it
replaced.

     11. Governing Law. This Warrant shall be governed by, and construed in
accordance with, the laws of the State of Delaware applicable to contracts made
therein.
