                              ALFACELL CORPORATION

            This certifies that, for value received, __________________________,
the registered holder hereof or assigns (the "Warrantholder") is entitled to
purchase from Alfacell Corporation, a Delaware corporation (the "Company"), at
any time on and after _____________, and before 5:00 p.m., New Jersey time, on
______________ (the "Termination Date"), at the purchase price of ________ per
share (the "Exercise Price"), the number of shares of Common Stock, par value
$.001 per share, of the Company set forth above (the "Warrant Stock"). The
number of shares of Warrant Stock, the Termination Date and the Exercise Price
per share of this Warrant shall be subject to adjustment from time to time as
set forth below.

SECTION I. TRANSFER OR EXCHANGE OF WARRANT.

      The Company shall be entitled to treat the Warrantholder as the owner in
fact hereof for all purposes and shall not be bound to recognize any equitable
or other claim to or interest in this Warrant on the part of any other person.
This Warrant shall be transferable only on the books of the Company, maintained
at its principal office upon delivery of this Warrant Certificate duly endorsed
by the Warrantholder or by his duly authorized attorney or representative, or
accompanied by proper evidence of succession, assignment or authority to
transfer. Upon any registration of transfer, the Company shall deliver a new

                                       3

SECTION II. TERM OF WARRANT; EXERCISE OF WARRANTS.

      A. Termination. The Company may, in its sole discretion, extend the
Termination Date with respect to the exercise of this Warrant upon notice to the
Warrantholder. As used herein, "Termination Date" shall be deemed to include any
such extensions.

      B. Exercise. This Warrant shall be exercised by surrender to the Company,
at its principal office, of this Warrant Certificate, together with the Purchase
Form attached hereto duly completed and signed, and upon payment to the Company
of the Exercise Price for the number of shares of Warrant Stock in respect of
which this Warrant is then exercised. Payment of the aggregate Exercise Price
shall be made in cash or by certified or official bank check.

      C. Warrant Certificate. Subject to Section III hereof, upon such surrender
of this Warrant Certificate and payment of the Exercise Price as aforesaid, the
Company shall issue and cause to be delivered to or upon the written order of
the Warrantholder a certificate or certificates for the number of full shares of
Warrant Stock so purchased upon the exercise of such Warrant, together with
cash, as provided in Section VI hereof, in respect of any fractional shares of
Warrant Stock otherwise issuable upon such surrender. Such certificate or
certificates representing the Warrant Stock shall be deemed to have been issued
and any person so designated to be named therein shall be deemed to have become
a holder of record of such shares of Warrant Stock as of the date of receipt by
the Company of this Warrant Certificate and payment of the Exercise Price as
aforesaid; provided, however, that if, at the date of surrender of this Warrant
Certificate and payment of the Exercise Price, the transfer books for the
Warrant Stock or other class of stock purchasable upon the exercise of this
Warrant shall be closed, the certificate or certificates for the shares of
Warrant Stock in respect of which this Warrant is then exercised shall be deemed
issuable as of the date on which such books shall next be opened (whether before
or after the Termination Date) and until such date the Company shall be under no
duty to deliver any certificate for such shares of Warrant Stock; provided
further, however, that the transfer books of record, unless otherwise required
by law, shall not be closed at any one time for a period longer than twenty (20)
days. The rights of purchase represented by this Warrant shall be exercisable,
at the election of the Warrantholder, either in full or from time to time in
part, and, in the event that this Warrant is exercised in respect of fewer than
all of the shares of Warrant Stock purchasable on such exercise at any time
prior to the Termination Date, a new Warrant Certificate evidencing the
remaining Warrant or Warrants will be issued, and the Company shall deliver the
new Warrant Certificate or Certificates pursuant to the provisions of this
Section.

                                       4
<PAGE>

SECTION III. PAYMENT OF TAXES.

      The Company will pay all documentary stamp taxes, if any, attributable to
the initial issuance of the shares of Warrant Stock upon the exercise of this
Warrant; provided, however, that the Warrantholder shall pay any tax or taxes
which may be payable in respect of any transfer involved in the issue or
delivery of Warrant Certificates or the certificates for the shares of Warrant
Stock in a name other than that of the Warrantholder in respect of which this
Warrant or shares of Warrant Stock are issued.

SECTION IV. MUTILATED OR MISSING WARRANT CERTIFICATES.

      In case this Warrant Certificate shall be mutilated, lost, stolen or
destroyed, the Company shall, at the request of the Warrantholder, issue and
deliver, in exchange and substitution for and upon cancellation of this
certificate if mutilated, or in lieu of and in substitution for this certificate
if lost, stolen or destroyed, a new Warrant Certificate of like tenor and
representing an equivalent right or interest, but only upon receipt of evidence
satisfactory to the Company of such loss, theft or destruction of this Warrant
Certificate and indemnity, if requested, also satisfactory to the Company.

SECTION V. RESERVATION OF SHARES OF WARRANT STOCK.

      There has been reserved, and the Company shall at all times keep reserved
so long as this Warrant remains outstanding, out of its authorized Common Stock
a number of shares of Common Stock sufficient to provide for the exercise of the
rights of purchase represented by this Warrant. The transfer agent for the
Common Stock and every subsequent transfer agent for any shares of the Company's
capital stock issuable upon the exercise of this Warrant will be irrevocably
authorized and directed at all times to reserve such number of authorized shares
as shall be requisite for such purpose.

                                       5
<PAGE>

SECTION VI. FRACTIONAL SHARES.

      No fractional shares or scrip representing fractional shares shall be
issued upon the exercise of this Warrant. With respect to any fraction of a
share called for upon the exercise of this Warrant, the Company shall pay to the
Warrantholder an amount in cash equal to such fraction multiplied by the current
market price of such fractional share. "Market Price", as of any date means, (i)
the last reported sale price for the shares of Common Stock as reported by the
National Association of Securities Dealers Automated Quotation National Market
System, ("NASDAQ-NMS"), (ii) the closing bid price for the shares of Common
Stock as reported by the National Association of Securities Dealers Automated
Quotation System ("NASDAQ") if the shares are not traded on NASDAQ-NMS, (iii)
the average of the closing bid and closing asked prices of the Common Stock as
reported by the National Quotations Bureau if the shares are not traded on
NASDAQ; (iv) the last reported sale price, if the shares of Common Stock are
listed on a national securities exchange or (v) if market value cannot be
calculated as of such date on any of the foregoing basis, the fair market price
determined by the Board of Directors of the Company, acting with reasonable
business judgment.

SECTION VII. EXERCISE PRICE; ANTI-DILUTION PROVISIONS.

      A. Exercise Price. The shares of Warrant Stock shall be purchasable upon
the exercise of this Warrant, at a price of _______ per share. The Company may,
in its sole discretion, reduce the Exercise Price applicable to the exercise of
this Warrant upon notice to the Warrantholder. As used herein, "Exercise Price"
shall be deemed to include any such reduction.

      If the Company shall at any time issue Common Stock by way of dividend or
other distribution on any stock of the Company or effect a stock split or
reverse stock split of the outstanding shares of Common Stock, the Exercise
Price shall be proportionately decreased in the case of such issuance (on the
day following the date fixed for determining stockholders entitled to receive
such dividend or other distribution or such stock split) or increased in the
case of such reverse stock split (on the date that such reverse stock split
shall become effective), by multiplying the Exercise Price in effect immediately
prior to the stock dividend or other distribution, stock split or reverse stock
split by a fraction, the numerator of which is the number of shares of Common
Stock outstanding immediately prior to such stock dividend or other
distribution, stock split or reverse stock split, and the denominator of which
is the number of shares of Common Stock outstanding immediately after such stock
dividend or other distribution, stock split or reverse stock split.

      B. No Impairment. The Company (a) will not increase the par value of any
shares of stock receivable upon the exercise of this Warrant above the amount
payable therefor upon such exercise, and (b) will take all such action as may be
necessary or appropriate in order that the Company may validly and legally issue
fully paid and nonassessable shares of Common Stock upon the exercise of this
Warrant.

                                       6
<PAGE>

      C. Number of Shares Adjusted. Upon any adjustment of the Exercise Price
pursuant to this Warrant, the Warrantholder shall thereafter (until another such
adjustment) be entitled to purchase upon the exercise of this Warrant, at the
new Exercise Price, the number of shares, calculated to the nearest full share,
obtained by multiplying the number of shares of Warrant Stock initially issuable
upon exercise of this Warrant by the Exercise Price in effect on the date hereof
and dividing the product so obtained by the new Exercise Price.

SECTION VIII. RECLASSIFICATION, REORGANIZATION OR MERGER.

      In case of any reclassification, capital reorganization or other change of
outstanding shares of Common Stock of the Company (other than a change in par
value or as a result of an issuance of Common Stock by way of dividend or other
distribution or of a stock split or reverse stock split) or in case of any
consolidation or merger of the Company with or into another corporation (other
than a merger with a subsidiary in which merger the Company is the continuing
corporation and which does not result in any reclassification, capital
reorganization or other change of outstanding shares of Common Stock of the
Company issuable upon exercise of this Warrant) or in case of any sale or
conveyance to another corporation of the property of the Company as an entirety
or substantially as an entirety, the Company shall cause effective provision to
be made so that the Warrantholder shall have the right thereafter, by exercising
this Warrant, to purchase the kind and amount of shares of stock and other
securities and property the Warrantholder would have been entitled to receive if
the Warrantholder had exercised this Warrant immediately prior to such
reclassification, capital reorganization or other change, consolidation, merger,
sale or conveyance. Any such provision shall include provision for adjustments
which shall be as nearly equivalent as may be practicable to the adjustments
provided for in this Warrant. The foregoing provisions of this Section shall
similarly apply to successive reclassifications, capital reorganizations and
changes of shares of Common Stock and to successive consolidations, mergers,
sales and conveyances.

SECTION IX. REGISTRATION RIGHTS.

      A. The Warrantholder shall have the registration rights with respect to
the resale of the Warrant Stock as set forth in Section 7 of the Purchase
Agreement by and between the Company and the Warrantholder of even date
herewith.

                                       7
<PAGE>

SECTION X. NOTICES TO WARRANTHOLDERS.

      So long as this Warrant shall be outstanding and unexercised (a) if the
Company shall pay any dividend or make any distribution upon the Common Stock or
(b) if the Company shall offer to the holders of Common Stock for subscription
or purchase by them any shares of stock of any class or any other rights or (c)
if any capital reorganization of the Company, reclassification of the capital
stock of the Company, consolidation or merger of the Company with or into
another corporation, sale, lease or transfer of all or substantially all of the
assets of the Company to another corporation, or the voluntary or involuntary
dissolution, liquidation or winding up of the Company shall be effected, then,

may be, a notice containing a brief description of the proposed action and
stating the date on which (i) a record is to be taken for the purpose of such
dividend or distribution, or (ii) such reclassification, reorganization,
consolidation, merger, conveyance, lease, dissolution, liquidation or winding up
is to take place and the date, if any, as of which the holders of Common Stock
of record shall be entitled to exchange their shares of Common Stock for
securities or other property deliverable upon such reclassification,
reorganization, consolidation, merger, conveyance, dissolution, liquidation or
winding up.

SECTION XI. NOTICES.

      Any notice pursuant to this Warrant by the Company or by the Warrantholder
shall be in writing and shall be deemed to have been duly given if delivered or

Attention: Kuslima Shogen, Chairman
           and Chief Executive Officer

Dear Ms. Shogen:

      The undersigned acknowledges that there is no minimum proceeds requirement
for the closing of this Offering, the Company may close only on the
undersigned's investment and such investment may be inadequate to meet the
Company's cash requirements. The Company intends to utilize the proceeds of this
Offering for research and development and general corporate purposes.

      The undersigned hereby subscribes to purchase _________ units at $_____
per unit (the "Unit"). Each Unit consists of ___ (_) shares of Common Stock,
$.001 par value per share (the "Shares") of Alfacell Corporation, a Delaware
corporation (the "Company") and ___ (_) _______ year warrant (the "Warrants").
The Warrants are exercisable into one (1) Share (the "Warrant Shares"). The
Shares, the Warrants and the Warrant Shares are being sold in a transaction
exempt from registration under the Securities Act of 1933, as amended (the
"Act"). The Warrants will be issued pursuant to a Warrant Agreement in the form
attached hereto as Exhibit A executed by the Company for the benefit of the
undersigned. The Warrants will be exercisable at $_______ for a _______ year
period commencing three months after its issuance. The undersigned tenders
herewith $_____________ in full payment of the purchase price for the
___________ Units to which the undersigned subscribes (in the manner indicated
on the signature page hereof.)

      The undersigned understands that the right to transfer all or any part of
the Shares, the Warrants and the Warrant Shares (hereinafter sometimes
collectively referred to as the "Securities") will be restricted. The
undersigned may not transfer the Securities unless they are registered under the
Act and applicable state securities or "blue sky" laws, or an exemption from
such registration is available. The undersigned recognizes that the Company
shall have no obligation to register the Securities, except as set forth herein.

The undersigned hereby represents, warrants and covenant that:

      1. The undersigned is acquiring the Shares and the Warrants, and at such
time as the undersigned may exercise the Warrants, the

                                  Page 1 of 15
<PAGE>

Warrant Shares, for the undersigned's own account for investment and not with a
view towards distribution. The undersigned will not sell, hypothecate, transfer
or otherwise dispose of the Securities unless such transaction has been
registered under the Act or, in the opinion of counsel for the Company, an
exemption from registration is available.

      2. (i) Please check here if the representation contained in this paragraph
2(i) is applicable to the undersigned _________. (A)If an individual, (a) the
undersigned's individual net worth or joint net worth with the undersigned's
spouse exceeds $1,000,000 as of the date hereof, or (b) the undersigned's
individual income has been in excess of $200,000 in each of 2002 and 2001 and is
expected to be in excess of $200,000 in 2003, or (c)the undersigned's joint
income with the undersigned's spouse has been in excess of $300,000 in each of
2002 and 2001 and is expected to be in excess of $300,000 in 2003; or (B) if a
corporation, partnership, or other entity, the foregoing representation applies
to all of the equity owners of the corporation, partnership, or entity.

            (ii) If a corporation, partnership, or other entity, was such a
corporation, partnership, or other entity formed for the specific purpose of
acquiring the Shares? _____Yes _____ No

            (iii) If the answer to 2(ii) is yes, how many equity owners does the
corporation partnership or entity have? _____

      3. Whether or not the representation contained in paragraph 2(i)is
applicable to the undersigned, the undersigned has adequate means of providing
for the undersigned's current needs and possible contingencies and has no need
for liquidity of the Securities. The undersigned's overall commitment to
investments is not disproportionate to the undersigned's net worth, and
acquisition of the Securities will not cause such overall commitment to become
excessive. Prior to the execution hereof, the undersigned has received and had
the opportunity to review, examine and read all documents, records and books
pertaining to this investment, including the Company's Annual Report on Form
10-K for the fiscal year ended July 31, 2002, the Company's Quarterly Reports on
Form 10-Q for each of the three quarterly periods subsequent to the fiscal year
ended July 31, 2002 collectively, the "Disclosure Documents").

      4. The undersigned is knowledgeable and experienced in financial and
business matters. The undersigned recognizes and is fully cognizant of the fact
that the investment contemplated hereby involves a high degree of risk. The
undersigned is able to evaluate the merits and risks of an investment in the
Securities. The undersigned has been given an opportunity to ask questions of,
and receive answers and obtain information from, representatives of the Company
concerning the Company.

                                  Page 2 of 15

      5. The undersigned has been given no oral or written representations or
assurances by the Company or any other person acting or purporting to act on
behalf of the Company in connection with the acquisition of the Securities, in
each case except as provided herein or in the Disclosure Documents.

      6. The undersigned understands and specifically acknowledges and agrees
that since the Securities have not been registered under the Act, the
certificates representing the Securities will bear a legend to such effect and a
stop transfer order will be placed on the Securities in the Company's transfer
books.

      7. By its acceptance hereof, the Company hereby agrees that it shall use
its best efforts to file a registration statement (the "Registration Statement")
under the Act to register the resale of the Shares and the Warrant Shares. The
Company further agrees to use its best efforts to cause such Registration
Statement to become effective.

      In connection with the Registration Statement, the undersigned shall
provide the Company, from time to time, as reasonably requested by the Company,
written information concerning its ownership of the Company's Securities, their
intentions concerning the sale of its Shares and Warrant Shares and such other
matters as are required in order to enable the Company to prepare, file and
obtain the effectiveness of such Registration Statement. Notwithstanding any of
the foregoing, the Company shall not be required to maintain the effectiveness
of the Registration Statement for more than two (2) years after the initial
effective date thereof.

      In connection with any such registration of Shares and Warrant Shares, the
Company shall supply a reasonable number of prospectuses to the undersigned, use
its best efforts to qualify the Shares and Warrants for sale in the states of
New York and New Jersey and furnish indemnification in the manner set forth
below.

      The Company shall bear the entire cost and expense of any such
registration hereunder. Notwithstanding the foregoing, the undersigned shall
bear the fees of all persons retained by it, such as counsel and accountants,
and any transfer taxes or underwriting discounts or commissions applicable to
the Shares and Warrant Shares sold by it pursuant to the Registration Statement.

      The Company shall indemnify and hold harmless each holder of Shares and
Warrant Shares that are registered pursuant to the Registration Statement and
each underwriter, within the meaning of the Act, who may purchase from or sell
for any such holder any such Shares or Warrant Shares and each person, if any,
who controls any

                                  Page 3 of 15
<PAGE>

such holder or underwriter within the meaning of the Act, from and against any
and all losses, claims, damages and liabilities caused by any untrue statement
of a material fact contained in the Registration Statement or any post-effective
amendment thereto or any prospectus included therein required to be filed or
furnished in connection therewith or caused by any omission to state therein a
material fact required to be stated therein in order to make the statements made
therein, in light of the circumstances under which they were made, not
misleading, except insofar as such losses, claims, damages or liabilities are
caused by any such untrue statement or omission based upon information furnished
or required to be furnished in writing to the Company by such holder or
underwriter expressly for use therein; provided, however, that such holder or
underwriter shall indemnify the Company, its directors, each officer signing the
Registration Statement and each person, if any, who controls the Company within
the meaning of the Act, from and against any and all losses, claims, damages and
liabilities caused by any untrue statement of a material fact contained in any
Registration Statement or any post-effective amendment thereto or any prospectus
included therein required to be filed or furnished pursuant thereto or caused by
any omission to state therein a material fact required to be stated therein in
order to make the statements made therein, in light of the circumstances under
which they were made, not misleading, insofar as such losses, claims, damages or
liabilities are caused by any untrue statement or omission based upon
information furnished in writing to the Company by any such holder or
underwriter expressly for use therein.

      If the indemnification provided for herein from either the holder of the
Shares and Warrant Shares or the Company is unavailable to an indemnified party
(the "Indemnitee") hereunder in respect of any losses, claims, damages or
liabilities (or actions in respect thereof) referred to herein, then the party
responsible for such indemnification (the "Indemnitor"), in lieu of indemnifying
the Indemnitee, shall contribute to the amount paid or payable by the Indemnitee
as a result of such losses, claims, damages or liabilities in such proportion as
is appropriate to reflect the relative fault of the Indemnitor and Indemnitee in
connection with the actions which resulted in such losses, claims, damages or
liabilities (including legal or other fees and expenses reasonably incurred in
connection with any investigation or proceeding) as well as any other equitable
considerations.

      If indemnification is available, the Indemnitor shall indemnify each
Indemnitee to the full extent provided for herein without regard to the relative
fault of the Indemnitor, the Indemnitee or any other equitable consideration
provided for hereunder.

                                  Page 4 of 15
<PAGE>

      After the Registration Statement becomes effective and in connection with
the sale of the Shares and Warrant Shares under such Registration Statement, the
undersigned shall take such steps as may be necessary to ensure that the offer
and sale thereof are in compliance with the requirements of the federal
securities laws, including, but not limited to, compliance with the
anti-manipulation requirements of the Securities Exchange Act of 1934, as
amended.

      By its acceptance hereof, the Company hereby acknowledges that the
foregoing accurately reflects its understanding concerning the transaction
contemplated hereby.

      WARRANT TO PURCHASE ___________ SHARES OF COMMON STOCK VOID AFTER 5:00
p.m. NEW JERSEY TIME, ON ________________. THIS WARRANT AND THE SHARES OF COMMON
STOCK ISSUABLE UPON THE EXERCISE HEREOF HAVE BEEN AND WILL BE ISSUED IN
TRANSACTIONS WHICH HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
AMENDED (THE "ACT"), OR UNDER ANY STATE SECURITIES OR BLUE SKY LAWS. THIS
WARRANT AND SUCH SHARES MAY NOT BE SOLD, TRANSFERRED, PLEDGED, HYPOTHECATED OR
OTHERWISE DISPOSED OF, IN WHOLE OR IN PART, IN THE ABSENCE OF AN EFFECTIVE
REGISTRATION STATEMENT UNDER THE ACT AND APPLICABLE STATE LAW, OR AN OPINION OF
COUNSEL ACCEPTABLE TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED.

NO.______                                                  ______________ SHARES

                              ALFACELL CORPORATION

            This certifies that, for value received,
___________________________, the registered holder hereof or assigns (the
"Warrantholder") is entitled to purchase from Alfacell Corporation, a Delaware
corporation (the "Company"), at any time on and after ___________________, and
before 5:00 p.m., New Jersey time, on _______________ (the "Termination Date"),
at the purchase price of $_______ per share (the "Exercise Price"), the number
of shares of Common Stock, par value $.001 per share, of the Company set forth
above (the "Warrant Stock"). The number of shares of Warrant Stock, the
Termination Date and the Exercise Price per share of this Warrant shall be
subject to adjustment from time to time as set forth below.

SECTION I. TRANSFER OR EXCHANGE OF WARRANT.

      The Company shall be entitled to treat the Warrantholder as the owner in
fact hereof for all purposes and shall not be bound to recognize any equitable
or other claim to or interest in this Warrant on the part of any other person.
This Warrant shall be transferable only on the books of the Company, maintained
at its principal office upon delivery of this Warrant Certificate duly endorsed
by the Warrantholder or by his duly authorized attorney or representative, or
accompanied by proper evidence of succession, assignment or authority to
transfer. Upon any registration of transfer, the Company shall deliver a new
Warrant Certificate or Certificates to the persons entitled thereto.

SECTION II. TERM OF WARRANT; EXERCISE OF WARRANTS.

      A. Termination. The Company may, in its sole discretion, extend the
Termination Date with respect to the exercise of this

                                  Page 7 of 15
<PAGE>

Warrant upon notice to the Warrantholder. As used herein, "Termination Date"
shall be deemed to include any such extensions.

      B. Exercise. This Warrant shall be exercised by surrender to the Company,
at its principal office, of this Warrant Certificate, together with the Purchase
Form attached hereto duly completed and signed, and upon payment to the Company
of the Exercise Price for the number of shares of Warrant Stock in respect of
which this Warrant is then exercised. Payment of the aggregate Exercise Price
shall be made in cash or by certified or official bank check.

      C. Warrant Certificate. Subject to Section III hereof, upon such surrender
of this Warrant Certificate and payment of the Exercise Price as aforesaid, the
Company shall issue and cause to be delivered to or upon the written order of
the Warrantholder a certificate or certificates for the number of full shares of
Warrant Stock so purchased upon the exercise of such Warrant, together with
cash, as provided in Section VI hereof, in respect of any fractional shares of
Warrant Stock otherwise issuable upon such surrender. Such certificate or
certificates representing the Warrant Stock shall be deemed to have been issued
and any person so designated to be named therein shall be deemed to have become
a holder of record of such shares of Warrant Stock as of the date of receipt by
the Company of this Warrant Certificate and payment of the Exercise Price as
aforesaid; provided, however, that if, at the date of surrender of this Warrant
Certificate and payment of the Exercise Price, the transfer books for the
Warrant Stock or other class of stock purchasable upon the exercise of this
Warrant shall be closed, the certificate or certificates for the shares of
Warrant Stock in respect of which this Warrant is then exercised shall be deemed
issuable as of the date on which such books shall next be opened (whether before
or after the Termination Date) and until such date the Company shall be under no
duty to deliver any certificate for such shares of Warrant Stock; provided
further, however, that the transfer books of record, unless otherwise required
by law, shall not be closed at any one time for a period longer than twenty (20)
days. The rights of purchase represented by this Warrant shall be exercisable,
at the election of the Warrantholder, either in full or from time to time in
part, and, in the event that this Warrant is exercised in respect of fewer than
all of the shares of Warrant Stock purchasable on such exercise at any time
prior to the Termination Date, a new Warrant Certificate evidencing the
remaining Warrant or Warrants will be issued, and the Company shall deliver the
new Warrant Certificate or Certificates pursuant to the provisions of this
Section.

SECTION III.  PAYMENT OF TAXES.

                                  Page 8 of 15
<PAGE>

      The Company will pay all documentary stamp taxes, if any, attributable to
the initial issuance of the shares of Warrant Stock upon the exercise of this
Warrant; provided, however, that the Warrantholder shall pay any tax or taxes
which may be payable in respect of any transfer involved in the issue or
delivery of Warrant Certificates or the certificates for the shares of Warrant
Stock in a name other than that of the Warrantholder in respect of which this
Warrant or shares of Warrant Stock are issued.

SECTION IV. MUTILATED OR MISSING WARRANT CERTIFICATES.

      In case this Warrant Certificate shall be mutilated, lost, stolen or
destroyed, the Company shall, at the request of the Warrantholder, issue and
deliver, in exchange and substitution for and upon cancellation of this
certificate if mutilated, or in lieu of and in substitution for this certificate
if lost, stolen or destroyed, a new Warrant Certificate of like tenor and
representing an equivalent right or interest, but only upon receipt of evidence
satisfactory to the Company of such loss, theft or destruction of this Warrant
Certificate and indemnity, if requested, also satisfactory to the Company.

SECTION V. RESERVATION OF SHARES OF WARRANT STOCK.

      There has been reserved, and the Company shall at all times keep reserved
so long as this Warrant remains outstanding, out of its authorized Common Stock
a number of shares of Common Stock sufficient to provide for the exercise of the
rights of purchase represented by this Warrant. The transfer agent for the
Common Stock and every subsequent transfer agent for any shares of the Company's
capital stock issuable upon the exercise of this Warrant will be irrevocably
authorized and directed at all times to reserve such number of authorized shares
as shall be requisite for such purpose.

SECTION VI. FRACTIONAL SHARES.

      No fractional shares or scrip representing fractional shares shall be
issued upon the exercise of this Warrant. With respect to any fraction of a
share called for upon the exercise of this Warrant, the Company shall pay to the
Warrantholder an amount in cash equal to such fraction multiplied by the current
market price of such fractional share. "Market Price", as of any date means, (i)
the last reported sale price for the shares of Common Stock as reported by the
National Association of Securities Dealers Automated Quotation National Market
System, ("NASDAQ-NMS"), (ii) the closing bid price for the shares of Common
Stock as reported by the National Association of Securities Dealers Automated
Quotation System ("NASDAQ") if the shares are not traded on NASDAQ-NMS, (iii)
the average of the closing bid and closing asked prices of the

                                  Page 9 of 15
<PAGE>

Common Stock as reported by the National Quotations Bureau if the shares are not
traded on NASDAQ; (iv) the last reported sale price, if the shares of Common
Stock are listed on a national securities exchange or (v) if market value cannot
be calculated as of such date on any of the foregoing basis, the fair market
price determined by the Board of Directors of the Company, acting with
reasonable business judgment.

SECTION VII. EXERCISE PRICE; ANTI-DILUTION PROVISIONS.

      A. Exercise Price. The shares of Warrant Stock shall be purchasable upon
the exercise of this Warrant, at a price of $____ per share. The Company may, in
its sole discretion, reduce the Exercise Price applicable to the exercise of
this Warrant upon notice to the Warrantholder. As used herein, "Exercise Price"
shall be deemed to include any such reduction.

      If the Company shall at any time issue Common Stock by way of dividend or
other distribution on any stock of the Company or effect a stock split or
reverse stock split of the outstanding shares of Common Stock, the Exercise
Price shall be proportionately decreased in the case of such issuance (on the
day following the date fixed for determining stockholders entitled to receive
such dividend or other distribution or such stock split) or increased in the
case of such reverse stock split (on the date that such reverse stock split
shall become effective), by multiplying the Exercise Price in effect immediately
prior to the stock dividend or other distribution, stock split or reverse stock
split by a fraction, the numerator of which is the number of shares of Common
Stock outstanding immediately prior to such stock dividend or other
distribution, stock split or reverse stock split, and the denominator of which
is the number of shares of Common Stock outstanding immediately after such stock
dividend or other distribution, stock split or reverse stock split.

      B. No Impairment. The Company (a) will not increase the par value of any
shares of stock receivable upon the exercise of this Warrant above the amount
payable therefor upon such exercise, and (b) will take all such action as may be
necessary or appropriate in order that the Company may validly and legally issue
fully paid and nonassessable shares of Common Stock upon the exercise of this
Warrant.

      C. Number of Shares Adjusted. Upon any adjustment of the Exercise Price
pursuant to this Warrant, the Warrantholder shall thereafter (until another such
adjustment) be entitled to purchase upon the exercise of this Warrant, at the
new Exercise Price, the number of shares, calculated to the nearest full share,
obtained by multiplying the number of shares of Warrant Stock initially issuable
upon exercise of this Warrant by the Exercise Price in

                                 Page 10 of 15
<PAGE>

effect on the date hereof and dividing the product so obtained by the new
Exercise Price.

SECTION VIII. RECLASSIFICATION, REORGANIZATION OR MERGER.

      In case of any reclassification, capital reorganization or other change of
outstanding shares of Common Stock of the Company (other than a change in par
value or as a result of an issuance of Common Stock by way of dividend or other
distribution or of a stock split or reverse stock split) or in case of any
consolidation or merger of the Company with or into another corporation (other
than a merger with a subsidiary in which merger the Company is the continuing
corporation and which does not result in any reclassification, capital
reorganization or other change of outstanding shares of Common Stock of the
Company issuable upon exercise of this Warrant) or in case of any sale or
conveyance to another corporation of the property of the Company as an entirety
or substantially as an entirety, the Company shall cause effective provision to
be made so that the Warrantholder shall have the right thereafter, by exercising
this Warrant, to purchase the kind and amount of shares of stock and other
securities and property the Warrantholder would have been entitled to receive if
the Warrantholder had exercised this Warrant immediately prior to such
reclassification, capital reorganization or other change, consolidation, merger,
sale or conveyance. Any such provision shall include provision for adjustments
which shall be as nearly equivalent as may be practicable to the adjustments
provided for in this Warrant. The foregoing provisions of this Section shall
similarly apply to successive reclassifications, capital reorganizations and
changes of shares of Common Stock and to successive consolidations, mergers,
sales and conveyances.

SECTION IX. REGISTRATION RIGHTS.

      A. The Warrantholder shall have the registration rights with respect to
the resale of the Warrant Stock as set forth in Section 7 of the Purchase
Agreement by and between the Company and the Warrantholder of even date
herewith.

SECTION X. NOTICES TO WARRANTHOLDERS.

      So long as this Warrant shall be outstanding and unexercised (a) if the
Company shall pay any dividend or make any distribution upon the Common Stock or
(b) if the Company shall offer to the holders of Common Stock for subscription
or purchase by them any shares of stock of any class or any other rights or (c)
if any capital reorganization of the Company, reclassification of the capital
stock of the Company, consolidation or merger of the Company with or into
another corporation, sale, lease or transfer of all or substantially all of the
assets of the Company to another corporation, or the voluntary or involuntary
dissolution,

                                 Page 11 of 15
<PAGE>

liquidation or winding up of the Company shall be effected, then, in any such
case, the Company shall cause to be delivered to the Warrantholder, at least ten
days prior to the date specified in (i) or (ii) below, as the case may be, a
notice containing a brief description of the proposed action and stating the
date on which (i) a record is to be taken for the purpose of such dividend or
distribution, or (ii) such reclassification, reorganization, consolidation,
merger, conveyance, lease, dissolution, liquidation or winding up is to take
place and the date, if any, as of which the holders of Common Stock of record
shall be entitled to exchange their shares of Common Stock for securities or
other property deliverable upon such reclassification, reorganization,
consolidation, merger, conveyance, dissolution, liquidation or winding up.

SECTION XI. NOTICES.

      Any notice pursuant to this Warrant by the Company or by the Warrantholder
shall be in writing and shall be deemed to have been duly given if delivered or
mailed certified mail, return receipt requested, (a) if to the Company, to it at
225 Belleville Avenue, Bloomfield, New Jersey 07003, Attention: Chief Executive
Officer and (b) if to the Warrantholder to the Warrantholder at the address set
forth on the signature page hereto. Each party hereto may from time to time
change the address to which such party's notices are to be delivered or mailed
hereunder by notice in accordance herewith to the other party.

SECTION XII. SUCCESSORS.

      All the covenants and provisions of this Warrant by or for the benefit of
the Company or the Warrantholder shall bind and inure to the benefit of their
respective successors and assigns hereunder.

SECTION XIII. APPLICABLE LAW.

      This Warrant shall be deemed to be a contract made under the laws of the
State of Delaware applicable to agreements made and to be performed entirely in
Delaware and for all purposes shall be construed in accordance with the internal
laws of Delaware without giving effect to the conflicts of laws principles
thereof.

SECTION XIV. BENEFITS OF THIS WARRANT.

      Nothing in this Warrant shall be construed to give to any person or
corporation other than the Company and the Warrantholder any legal or equitable
right, remedy or claim under this Warrant and this Warrant shall be for the sole
