<PAGE>

                  (e) The term "REGISTRATION RIGHTS AGREEMENT" shall mean the
Registration Rights Agreement, dated as of December 1, 2000, between the Company
and the Investor signatory thereto.

                  (f) The term "WARRANT HOLDER" shall mean the Purchaser or any
assignee of all or any portion of this Warrant.

                  (g) The term "WARRANT SHARES" shall mean the shares of Common
Stock or other securities issuable upon exercise of this Warrant.

         Capitalized terms used but not defined in this Warrant shall have the
meanings specified in the Agreement or the Debentures.

         2. EXERCISE OF WARRANT.

         This Warrant may be exercised by the Warrant Holder, in whole or in
part, at any time and from time to time by either of the following methods:

                  (a) The Warrant Holder may surrender this Warrant, together
with the form of subscription at the end of the term duly executed by Warrant
Holder ("SUBSCRIPTION NOTICE"), at the offices of the Company or any transfer
agent for the Common Stock; or

                  (b) The Warrant Holder may also exercise this Warrant, in
whole or in part, in a "cashless" or "net-issue" exercise by delivering to the
offices of the Company or any transfer agent for the Common Stock this Warrant,
together with a Subscription Notice specifying the number of Warrant Shares to
be delivered to such Warrant Holder ("DELIVERABLE SHARES") and the number of
Warrant Shares with respect to which this Warrant is being surrendered in
payment of the aggregate Purchase Price for the Deliverable Shares ("SURRENDERED
SHARES"); PROVIDED that the Purchase Price multiplied by the number of
Deliverable Shares shall not exceed the value of the Surrendered Shares. For the
purposes of this provision, each Warrant Share as to which this Warrant is
surrendered will be attributed a value equal to the fair market value (as
defined below) of the Warrant Share minus the Purchase Price of the Warrant
Share.

         In the event that the Warrant is not exercised in full, the number of
Warrant Shares shall be reduced by the number of such Warrant Shares for which
this Warrant is exercised and/or surrendered, and the Company, at its expense,
shall within three (3) Trading Days (as defined below) issue and deliver to or
upon the order of Warrant Holder a new Warrant of like tenor in the name of
Warrant Holder or as Warrant Holder (upon payment by Warrant Holder of any
applicable transfer taxes) may request, reflecting such adjusted Warrant Shares.



                                       2
<PAGE>



         3. DELIVERY OF STOCK CERTIFICATES.

                  (a) Subject to the terms and conditions of this Warrant, as
soon as practicable after the exercise of this Warrant in full or in part, and
in any event within three (3) Trading Days thereafter, the Company shall
transmit the certificates of the Warrant Shares (together with any other stock
or other securities or property to which Warrant Holder is entitled upon
exercise) by messenger or overnight delivery service to reach the address
designated by such holder within three (3) Trading Days after the receipt of the
Subscription Notice ("T+3"). If such certificates are not received by the
Warrant Holder within T+3, then the Warrant Holder will be entitled to revoke
and withdraw its exercise of its Warrant at any time prior to its receipt of
those certificates.

                  In lieu of delivering physical certificates representing the
Warrant Shares deliverable upon exercise of Warrants, provided the Company's
transfer agent is participating in the Depository Trust Company ("DTC") Fast
Automated Securities Transfer ("FAST") program, upon request of the Warrant
Holder, the Company shall use its best efforts to cause its transfer agent to
electronically transmit the Warrant Shares issuable upon exercise to the Warrant
Holder, by crediting the account of Warrant Holder's prime broker with DTC
through its Deposit Withdrawal Agent Commission ("DWAC") system. The time
periods for delivery described above shall apply to the electronic transmittals
through the DWAC system. The parties agree to coordinate with DTC to accomplish
this objective. The exchange pursuant to Section 3 shall be deemed to have been
made immediately prior to the close of business on the date of the Subscription
Notice. The person or persons entitled to receive the Warrant Shares issuable
upon such exercise shall be treated for all purposes as the record holder or
holders of such Warrant Shares at the close of business on the date of the
Subscription Notice.

                  The term Trading Day means (x) if the Common Stock is listed
on the New York Stock Exchange or the American Stock Exchange, a day on which
there is trading on such stock exchange, (y) if the Common Stock is not listed
on either of such stock exchanges but sale prices of the Common Stock are
reported on an automated quotation system, a day on which trading is reported on
the principal automated quotation system on which sales of the Common Stock are
reported, or (z) if the foregoing provisions are inapplicable, a day on which
quotations are reported by National Quotation Bureau Incorporated.

                  (b) This Warrant may not be exercised as to fractional shares
of Common Stock. In the event that the exercise of this Warrant, in full or in
part, would result in the issuance of any fractional share of Common Stock, then
in such event the Warrant Holder shall be entitled to cash equal to the fair
market value of such fractional share. For purposes of this Warrant, "FAIR
MARKET VALUE" shall equal the closing trading price of the Common Stock on the
Approved Market which is the principal trading exchange or market for the Common
Stock (the "PRINCIPAL MARKET") on the date of determination or, if the Common
Stock is not listed or admitted to trading on any Approved Market, the average
of the closing bid and asked prices on the over-the-counter market as furnished
by any New York Stock Exchange member firm reasonably selected from time to time


                                       3
<PAGE>


by the Company for that purpose and reasonably acceptable to the Warrant Holder,
or, if the Common Stock is not listed or admitted to trading on any Approved
Market or traded over-the-counter and the average price cannot be determined as
contemplated above, the fair market value of the Common Stock shall be as
reasonably determined in good faith by the Company's Board of Directors with the
concurrence of the Warrant Holder.

         4. (A) REPRESENTATIONS AND COVENANTS OF THE COMPANY.

                  (a) The Company shall comply with its obligations under the
Registration Rights Agreement with respect to the Warrant Shares, including,
without limitation, the Company's obligation to have filed and declared and
maintained effective a registration statement registering the Warrant Shares
under the Securities Act of 1933, as amended (the "ACT").

                  (b) The Company shall take all necessary action and
proceedings as may be required and permitted by applicable law, rule and
regulation, including, without limitation, the notification of the Principal
Market, for the legal and valid issuance of this Warrant and the Warrant Shares
to the Warrant Holder under this Warrant.

                  (c) From the date hereof through the last date on which this
Warrant is exercisable, the Company shall take all steps necessary to insure
that the Common Stock remains listed on the Principal Market.

                  (d) The Warrant Shares, when issued in accordance with the
terms hereof, will be duly authorized and, when paid for or issued in accordance
with the terms hereof, shall be validly issued, fully paid and non-assessable.
The Company has authorized and reserved for issuance to Warrant Holder the
requisite number of shares of Common Stock to be issued pursuant to this
Warrant.

                  (e) The Company shall at all times reserve and keep available,
solely for issuance and delivery as Warrant Shares hereunder, 100% of such
number of shares of Common Stock as shall from time to time be issuable
hereunder.

                  (f) With a view to making available to the Warrant Holder the
benefits of Rule 144 promulgated under the Act and any other rule or regulation
of the Securities and Exchange Commission ("SEC") that may at any time permit
Warrant Holder to sell securities of the Company to the public without
registration, the Company agrees to use its best efforts to:

                           (i) make and keep public information available, as
                  those terms are understood and defined in Rule 144, at all
                  times;

                           (ii) file with the SEC in a timely manner all reports
                  and other documents required of the Company under the Act and
                  the Securities Exchange Act of 1934, as amended (the "EXCHANGE
                  ACT"); and



                                       4
<PAGE>

                           (iii) furnish to any Warrant Holder forthwith upon
                  request a written statement by the Company that it has
                  complied with the reporting requirements of Rule 144 and of
                  the Act and the Exchange Act, a copy of the most recent annual
                  or quarterly report of the Company, and such other reports and
                  documents so filed by the Company as may be reasonably
                  requested to permit any such Warrant Holder to take advantage
                  of any rule or regulation of the SEC permitting the selling of
                  any such securities without registration.

                  (B) REPRESENTATIONS AND COVENANTS OF THE PURCHASER.

                  The Purchaser shall not resell Warrant Shares, unless such
resale is pursuant to an effective registration statement under the Act or
pursuant to an applicable exemption from such registration requirements.

         5. ADJUSTMENT OF PURCHASE PRICE AND NUMBER OF SHARES. The number of and
kind of securities purchasable upon exercise of this Warrant and the Purchase
Price shall be subject to adjustment from time to time as follows:

                  (a) SUBDIVISIONS, COMBINATIONS AND OTHER ISSUANCES. If the
Company shall at any time after the date hereof but prior to the expiration of
this Warrant subdivide its outstanding securities as to which purchase rights
under this Warrant exist, by split-up, spin-off, or otherwise, or combine its
outstanding securities as to which purchase rights under this Warrant exist, the
number of Warrant Shares as to which this Warrant is exercisable as of the date
of such subdivision, split-up, spin-off or combination shall forthwith be
proportionately increased in the case of a subdivision, or proportionately
decreased in the case of a combination. Appropriate proportional adjustments
(decrease in the case of subdivision, increase in the case of combination) shall
also be made to the Purchase Price payable per share, so that the aggregate
Purchase Price payable for the total number of Warrant Shares purchasable under
this Warrant as of such date shall remain the same as it would have been before
such subdivision or combination.

                  (b) STOCK DIVIDEND. If at any time after the date hereof the
Company declares a dividend or other distribution on Common Stock payable in
Common Stock or other securities or rights convertible into or exchangeable for
Common Stock ("COMMON STOCK EQUIVALENTS") without payment of any consideration
by holders of Common Stock for the additional shares of Common Stock or the
Common Stock Equivalents (including the additional shares of Common Stock
issuable upon exercise or conversion thereof), then the number of shares of
Common Stock for which this Warrant may be exercised shall be increased as of
the record date (or the date of such dividend distribution if no record date is
set) for determining which holders of Common Stock shall be entitled to receive
such dividends, in proportion to the increase in the number of outstanding
shares (and shares of Common Stock issuable upon conversion of all such
securities convertible into Common Stock) of Common Stock as a result of such
dividend, and the Purchase Price shall be proportionately reduced so that the
aggregate Purchase Price for all the Warrant Shares issuable hereunder



                                       5
<PAGE>

immediately after the record date (or on the date of such distribution, if
applicable) for such dividend shall equal the aggregate Purchase Price so
payable immediately before such record date (or on the date of such
distribution, if applicable).

                  (c) OTHER DISTRIBUTIONS. If at any time after the date hereof
the Company distributes to holders of its Common Stock, other than as part of
its dissolution, liquidation or the winding up of its affairs, any shares of its
capital stock, any evidence of indebtedness or any of its assets (other than
Common Stock), then the number of Warrant Shares for which this Warrant is
exercisable shall be increased to equal: (i) the number of Warrant Shares for
which this Warrant is exercisable immediately prior to such event, (ii)
multiplied by a fraction, (A) the numerator of which shall be the fair market
value per share of Common Stock on the record date for the dividend or
distribution, and (B) the denominator of which shall be the fair market value
price per share of Common Stock on the record date for the dividend or
distribution minus the amount allocable to one share of Common Stock of the
value (as jointly determined in good faith by the Board of Directors of the
Company and the Warrant Holder) of any and all such evidences of indebtedness,
shares of capital stock, other securities or property, so distributed. The
Purchase Price shall be reduced to equal: (i) the Purchase Price in effect
immediately before the occurrence of any event (ii) multiplied by a fraction,
(A) the numerator of which is the number of Warrant Shares for which this
Warrant is exercisable immediately before the adjustment, and (B) the
denominator of which is the number of Warrant Shares for which this Warrant is
exercisable immediately after the adjustment.

                  (d) MERGER, ETC. If at any time after the date hereof there
shall be a merger or consolidation of the Company with or into or a transfer of
all or substantially all of the assets of the Company to another entity, then
the Warrant Holder shall be entitled to receive upon or after such transfer,
merger or consolidation becoming effective, and upon payment of the Purchase
Price then in effect, the number of shares or other securities or property of
the Company or of the successor corporation resulting from such merger or
consolidation, which would have been received by Warrant Holder for the shares
of stock subject to this Warrant had this Warrant been exercised just prior to
such transfer, merger or consolidation becoming effective or to the applicable
record date thereof, as the case may be. The Company will not merge or
consolidate with or into any other corporation, or sell or otherwise transfer
its property, assets and business substantially as an entirety to another
corporation, unless the corporation resulting from such merger or consolidation
(if not the Company), or such transferee corporation, as the case may be, shall
expressly assume, by supplemental agreement reasonably satisfactory in form and
substance to the Warrant Holder, the due and punctual performance and observance
of each and every covenant and condition of this Warrant to be performed and
observed by the Company.

                  (e) RECLASSIFICATION, ETC. If at any time after the date
hereof there shall be a reorganization or reclassification of the securities as
to which purchase rights under this Warrant exist into the same or a different
number of securities of any other class or classes, then the Warrant Holder
shall thereafter be entitled to receive upon exercise of this Warrant, during
the period specified herein and upon payment of the Purchase Price then in
effect, the number of shares or other securities or property resulting from such



                                       6
<PAGE>

reorganization or reclassification, which would have been received by the
Warrant Holder for the shares of stock subject to this Warrant had this Warrant
at such time been exercised.

         6. NO IMPAIRMENT. 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 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 action as may be
necessary or appropriate in order to protect the rights of the Warrant Holder
against impairment. Without limiting the generality of the foregoing, the
Company (a) will not increase the par value of any Warrant Shares above the
amount payable therefor on such exercise, and (b) will take all such action as
may be reasonably necessary or appropriate in order that the Company may validly
and legally issue fully paid and nonassessable Warrant Shares on the exercise of
this Warrant.

         7. RIGHTS AS STOCKHOLDER. Prior to exercise of this Warrant, the
Warrant Holder shall not be entitled to any rights as a stockholder of the
Company with respect to the Warrant Shares, including (without limitation) the
right to vote such shares, receive dividends or other distributions thereon or
be notified of stockholder meetings. However, in the event of any taking by the
Company of a record of the holders of any class of securities for the purpose of
determining the holders thereof who are entitled to receive any dividend (other
than a cash dividend) or other distribution, any right to subscribe for,
purchase or otherwise acquire any shares of stock of any class or any other
securities or property, or to receive any other right, the Company shall mail to
each Warrant Holder, at least 10 Trading Days prior to the date specified
therein, a notice specifying the date on which any such record is to be taken
for the purpose of such dividend, distribution or right, and the amount and
character of such dividend, distribution or right.

         8. REPLACEMENT OF WARRANT. On 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 of this
Warrant, on delivery of an indemnity agreement or security reasonably
satisfactory in form and amount to the Company or, in the case of any such
mutilation, on surrender and cancellation of such Warrant, the Company at its
expense promptly will execute and deliver, in lieu thereof a new Warrant of like
tenor.

         9. SPECIFIC PERFORMANCE; CONSENT TO JURISDICTION; CHOICE OF LAW.

                  (a) The Company and the Warrant Holder acknowledge and agree
that irreparable damage would occur in the event that any of the provisions of
this Warrant were not performed in accordance with their specific terms or were
otherwise breached. It is accordingly agreed that the parties shall he entitled
to an injunction or injunctions to prevent or cure breaches of the provisions of
this Warrant and to enforce specifically the terms and provisions hereof, this
being in addition to any other remedy to which either of them may be entitled by
law or equity.



                                       7
<PAGE>

                  (b) Each of the Company and the Warrant Holder (i) hereby
irrevocably submits to the exclusive jurisdiction of the state and federal
courts located in New Jersey for the purposes of any suit, action or proceeding
arising out of or relating to this warrant and (ii) hereby waives, and agrees
not to assert in any such suit, action or proceeding, any claim that it is not
personally subject to the jurisdiction of such court, that the suit, action or
proceeding is brought in an inconvenient forum or that the venue of the suit,
action or proceeding is improper. Each of the Company and the Warrant Holder
consents to process being served in any such suit, action or proceeding by
mailing a copy thereof to such party at the address in effect for notices to it
under this Warrant and agrees that such service shall constitute good and
sufficient service of process and notice thereof. Nothing in this paragraph
shall affect or limit any right to serve process in any other manner permitted
by applicable law.

                  (c) The Company and the Warrant Holder irrevocably waive their
right to trial by jury.

                  (d) This Warrant shall be governed by and construed and
enforced in accordance with the internal laws of the State of New Jersey
applicable to contracts executed and to be performed entirely within such State.

         10. ENTIRE AGREEMENT; AMENDMENTS. This Warrant, the Exhibits hereto and
the provisions contained in the Agreement or the Registration Rights Agreement
or the Debentures contain the entire understanding of the parties with respect
to the matters covered hereby and thereby and, except as specifically set forth
herein and therein, neither the Company nor the Warrant Holder makes any
representation, warranty, covenant or undertaking with respect to such matters.
No provision of this Agreement may be waived or amended other than by a written
instrument signed by the party against whom enforcement of any such amendment or
waiver is sought.

         11. NOTICES. Any notice or other communication required or permitted to
be given hereunder shall be in writing and shall be effective (a) upon hand
