Agreement, expressly agree to such terms and provisions and to be bound thereby.

the outstanding Warrants as shall be specified therein and shall provide that it

Warrants, the exercising Holder whose name appears on a securities position

such Holder or its agent or attorney and (ii) payment of the Warrant Price to

with respect to the issuance or delivery of the Warrants or any transfer
thereof.

of Common Stock upon exercise of any Warrant. Whenever any distribution of
Warrants exercisable into fractional shares of Common Stock would otherwise be
called for, the actual distribution thereof shall be rounded as follows: (i)
fractions of 1/2 or greater shall be rounded to the next higher whole number and
(ii) fractions of less than 1/2 shall be rounded to the next lower whole number.

    5. Transfer and Exchange.

           5.1 Transfer and Exchange of Global Warrants. A Global Warrant may
not be transferred as a whole except by the Depositary to a nominee of the
Depositary, by a nominee of the Depositary to the Depositary or to another
nominee of the Depositary, or by the Depositary or any such nominee to a
successor Depositary or a nominee of such successor Depositary. All Global
Warrants will be exchanged by the Company for Definitive Warrants if (i) the
Company delivers to the Warrant Agent notice from the Depositary that it is
unwilling or unable to continue to act as Depositary or that it is no longer a
clearing agency registered under the Exchange Act and, in either case, a
successor Depositary is not appointed by the Company within 120 days after the
date of such notice from the Depositary or (ii) the Company in its sole
discretion determines that the Global Warrants (in whole but not in part) should
be exchanged for Definitive Warrants and delivers a written notice to such
effect to the Warrant Agent. Upon the occurrence of either of the preceding
events, Definitive Warrants shall be issued in such names as the Depositary
shall instruct the Warrant Agent. Global Warrants may also be exchanged or
replaced, in whole or in part, as provided in Section 11 hereof. A Global
Warrant may not be exchanged for another Warrant other than as provided in this
Section 5.1; however, beneficial interests in a Global Warrant may be
transferred and exchanged as provided in Section 5.2 hereof.

           5.2 Transfer and Exchange of Beneficial Interests in the Global
Warrants. The transfer and exchange of beneficial interests in the Global
Warrants shall be effected through the Depositary, in accordance with the
Applicable Procedures.

           5.3 Transfer and Exchange of Definitive Warrants for Definitive
Warrants. Upon request by a holder of Definitive Warrants and such holder's
compliance with the provisions of this Section 5.3, the Warrant Registrar shall
register the transfer or exchange of Definitive Warrants on the Warrant
Register. Prior to such registration of transfer or exchange, the requesting
holder shall present or surrender to the Warrant Registrar the Definitive
Warrants duly endorsed or accompanied by a written instruction of transfer in
form satisfactory to the Warrant Registrar duly executed by such holder or by
its attorney, duly authorized in writing.


                                     1.91-5

           5.4 Global Warrant Legend. Each Global Warrant shall bear a legend in
substantially the following form:

           "THIS GLOBAL WARRANT IS HELD BY THE DEPOSITARY (AS DEFINED IN THE
           WARRANT AGREEMENT GOVERNING THIS WARRANT) OR ITS NOMINEE IN CUSTODY
           FOR THE BENEFIT OF THE BENEFICIAL OWNERS HEREOF, AND IS NOT
           TRANSFERABLE TO ANY PERSON UNDER ANY CIRCUMSTANCES EXCEPT THAT (I)
           THE WARRANT AGENT MAY MAKE SUCH NOTATIONS HEREON AS MAY BE REQUIRED
           PURSUANT TO SECTION 5 OF THE WARRANT AGREEMENT, (ii) this global
           warrant may be exchanged in whole but not in part pursuant to section
           5.1 of the warrant agreement, (III) THIS GLOBAL WARRANT MAY BE
           DELIVERED TO THE WARRANT AGENT FOR CANCELLATION PURSUANT TO SECTION
           13.5 OF THE WARRANT AGREEMENT AND (Iv) THIS GLOBAL WARRANT MAY BE
           TRANSFERRED TO A SUCCESSOR DEPOSITARY WITH THE PRIOR WRITTEN CONSENT
           OF THE COMPANY."

           5.5 General Provisions Relating to Transfers and Exchanges.

               (a) To permit registrations of transfers and exchanges, the
Company shall execute and the Warrant Agent shall countersign Global Warrants
and Definitive Warrants upon the Company's order or at the Warrant Registrar's
request.

               (b) No service charge shall be made to a holder of a beneficial
interest in a Global Warrant or to a holder of a Definitive Warrant for any
registration of transfer or exchange, but the Company may require payment of a
sum sufficient to cover any transfer tax or governmental charge payable in
connection therewith.

               (c) All Global Warrants and Definitive Warrants issued upon any
registration of transfer or exchange of Global Warrants or Definitive Warrants
shall be duly authorized, executed and issued Warrants for Common Stock of the
Company, not subject to any preemptive rights, and entitled to the same benefits
under this Warrant Agreement, as the Global Warrants or Definitive Warrants
surrendered upon such registration of transfer or exchange.

               (d) Prior to due presentment for the registration of a transfer
of any Warrant, the Warrant Agent, and the Company may deem and treat the Person
in whose name any Warrant is registered as the absolute owner of such Warrant
for all purposes and neither the Warrant Agent nor the Company shall be affected
by notice to the contrary.

               (e) The Warrant Agent shall countersign Global Warrants and
Definitive Warrants in accordance with the provisions of Section 3.4 hereof.

           5.6 Facsimile Submissions to Warrant Agent. All instructions required
to be submitted to the Warrant Registrar pursuant to this Section 5 to effect a
registration of transfer or exchange may be submitted by facsimile.

    6. Adjustments. The number of shares of Common Stock for which a Warrant is
exercisable, and the Exercise Price shall be subject to adjustment from time to
time as set forth in this Section 6.


                                     1.91-6

           6.1 Stock Dividends, Subdivisions and Combinations. If at any time
the Company shall: (i) take a record of the holders of its Common Stock for the
purpose of entitling them to receive a dividend payable in, or other
distribution of, additional shares of Common Stock; (ii) subdivide its
outstanding shares of Common Stock into a larger number of shares of Common
Stock, or (iii) combine its outstanding shares of Common Stock into a smaller
number of shares of Common Stock, then (a) the number of shares of Common Stock
for which a Warrant is exercisable immediately after the occurrence of any such
event shall be adjusted to equal the number of shares of Common Stock that a
record holder of the same number of shares of Common Stock for which a Warrant
is exercisable immediately prior to the occurrence of such event would own or be
entitled to receive after the happening of such event and (b) the Exercise Price
shall be adjusted to equal (1) the Exercise Price prior to such adjustment
multiplied by the number of shares of Common Stock for which a Warrant is
exercisable immediately prior to the adjustment divided by (2) the number of
shares for which a Warrant is exercisable immediately after such adjustment.

           6.2 Other Provisions Applicable to Adjustments under this Section.
The following provisions shall be applicable to the making of adjustments of the
number of shares of Common Stock for which a Warrant is exercisable and the
Exercise Price provided for in this Section 6:

               (a) When Adjustments to Be Made. The adjustments required by this
Section 6 shall be made whenever and as often as any specified event requiring
an adjustment shall occur, except that any adjustment of the number of shares of
Common Stock for which a Warrant is exercisable that otherwise would be required
may be postponed (except in the case of a subdivision or combination of shares
of Common Stock, as provided for in Section 6.1) up to, but not later than the
date of exercise if such adjustment either by itself or with other adjustments
not previously made would result in an increase or decrease, as the case may be,
of less than 1% of the shares of Common Stock for which a Warrant is exercisable
immediately prior to the making of such adjustment. Any adjustment representing
a change of less than such minimum amount (except as aforesaid) which is
postponed shall be carried forward and made as soon as such adjustment, together
with other adjustments required by this Section 6 and not previously made, would
result in a minimum adjustment or on the date of exercise. For the purpose of
any adjustment, any specified event shall be deemed to have occurred at the
close of business on the date of its occurrence.

               (b) Fractional Interests. In computing adjustments pursuant to
this Section 6 (but subject to Section 4.3), fractional interests in Common
Stock shall be taken into account to the nearest 1/1000th of a share.

           6.3 Reorganization, Reclassification, Merger, Consolidation or Sale
of Substantially all Assets of the Company. If the Company (or any other entity,
the stock or other securities of which are at the time receivable on the
exercise of the Warrants) shall reorganize its capital, reclassify its capital
stock, consolidate or merge with or into another Person (where the Company is
not the surviving corporation or resulting entity or where there is a change in
or distribution with respect to the Common Stock of the Company), other than as
a result of a stock dividend, stock split, reverse stock split, recapitalization
or the like provided for in Section 6.1 above (each such event hereinafter


                                     1.91-7

referred to as a "Transaction"), and pursuant to the terms of any such
Transaction, the consideration to be paid or distributed to or otherwise
received by the holders of Common Stock consists of shares of common stock of
the surviving corporation or resulting entity and/or any cash, shares of stock
(not constituting common stock) or other securities or property of any nature
whatsoever (including warrants or other subscription or purchase rights) (such
non-common stock property hereinafter referred to as "Other Property"), then
each Holder shall have the right thereafter to receive, upon exercise of a
Warrant, solely the number of shares of common stock of the surviving
corporation or resulting entity and/or such amount of Other Property receivable
pursuant to such Transaction by a holder of the number of shares of Warrant
Stock for which a Warrant is exercisable immediately prior to the effective time
of such Transaction. In the case of any Transaction of the type described in the
preceding sentence, it shall be a condition precedent to consummation of the
Transaction that the surviving corporation or resulting entity assume the due
and punctual observance and performance of each and every covenant and condition
of this Warrant Agreement and the Warrants to be performed and observed by the
Company and all the obligations and liabilities hereunder, subject to such
modifications as may be deemed appropriate (as determined by resolution of the
Board of Directors of the Company) in order to provide for adjustments of shares
of the Warrant Stock for which a Warrant is exercisable which shall be as nearly
equivalent as practicable to the adjustments provided for in this Section 6.3.
For purposes of this Section 6.3, "common stock of the surviving corporation or
resulting entity" shall include stock of such corporation of any class which
does not have a preference as to dividends or assets over any other class of
stock of such corporation and which is not subject to redemption and shall also
include any evidences of indebtedness, shares of stock or other securities which
are convertible into or exercisable or exchangeable for any such stock, either
immediately or after the lapse of any prescribed time period or the occurrence
of a specified event, and any warrants or other rights to subscribe for or
purchase any such stock. The foregoing provisions of this Section 6.3 shall
similarly apply to successive Transactions.

           6.4 Certain Limitations. Notwithstanding anything herein to the
contrary, the Company agrees not to enter into any transaction which, by reason
of any adjustment hereunder, would cause the Exercise Price to be less than the
par value per share of Common Stock unless the Company shall take such corporate
action in order that the Company may validly and legally issue fully paid and
nonassessable shares of such Common Stock at such adjusted Exercise Price.

    7. Notice to Warrant Holders. Whenever the number of shares of Common Stock
for which a Warrant is exercisable, or whenever the Exercise Price shall be
adjusted pursuant to Section 6, the Company shall forthwith prepare a
certificate setting forth, in reasonable detail, the event requiring the
adjustment and the method by which such adjustment was calculated, specifying
the number of shares of Common Stock for which a Warrant is exercisable and
describing the number and kind of any other shares of stock or Other Property
for which a Warrant is exercisable, and any change in the purchase price or
prices thereof, after giving effect to such adjustment or change. The Company
shall promptly cause a signed copy of such certificate to be delivered to the
Warrant Agent in accordance with Section 14.2. The Company shall keep at its
office or agency designated by the Company pursuant to Section 12 copies of all
such certificates and cause the same to be available for inspection at said
office during normal business hours by any Holder or any prospective purchaser
of a Warrant designated by a Holder thereof.


                                     1.91-8

    8. No Impairment. The Company shall not by any action, including, without
limitation, amending its certificate of incorporation or through any
reorganization, transfer of assets, consolidation, merger, dissolution, issue or
sale of securities or any other voluntary action, avoid or seek to avoid the
observance or performance of any of the terms of this Warrant Agreement or any
Warrant. Without limiting the generality of the foregoing, the Company will (i)
not increase the par value of any shares of Common Stock receivable upon the
exercise of a Warrant above the amount payable therefor upon such exercise
immediately prior to such increase in par value and (ii) 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 any Warrant.

    9. Reservation and Authorization of Common Stock. From and after the date
hereof, the Company shall at all times reserve and keep available for issue upon
the exercise of Warrants such number of its authorized but unissued shares of
Common Stock as will be sufficient to permit the exercise in full of all
outstanding Warrants. All shares of Common Stock which shall be so issuable,
when issued upon exercise of any Warrant and payment therefor in accordance with
the terms of this Warrant Agreement and such Warrant, shall be duly and validly
issued and fully paid and nonassessable, and not subject to preemptive rights.

    10. Stock and Warrant Transfer Books. The Company will not at any time,
except upon dissolution, liquidation or winding up of the Company, close its
stock transfer books or Warrant transfer books so as to result in preventing or
delaying the exercise or transfer of any Warrant.

    11. Loss or Mutilation. Upon receipt by the Company and the Warrant Agent
from any Holder of evidence reasonably satisfactory to them of the ownership of
and the loss, theft, destruction or mutilation of such Holder's Warrant and
indemnity reasonably satisfactory to them, and in case of mutilation upon
surrender and cancellation thereof, the Company will execute and the Warrant
Agent will countersign and deliver in lieu hereof a new Warrant of like tenor
and representing an equal number of Warrants to such Holder; provided, in the
case of mutilation, no indemnity shall be required if such Warrant in
identifiable form is surrendered to the Company or the Warrant Agent for
cancellation.

    12. Office of Company. As long as any of the Warrants remain outstanding,
the Company shall maintain an office or agency (which may be the principal
executive offices of the Company) where the Warrants may be presented for
exercise, registration of transfer, division or combination as provided in this
Warrant Agreement. The Company shall initially maintain such an agency at the
Warrant Agent's Principal Offices.

    13. Warrant Agent.

           13.1 Merger or Consolidation or Change of Name of Warrant Agent. Any
Person into which the Warrant Agent may be merged or with which it may be
consolidated, or any Person resulting from any merger or consolidation to which
the Warrant Agent shall be a party, or any Person succeeding to all or
substantially all of the corporate trust business of the Warrant Agent, shall be
the successor to the Warrant Agent hereunder without the execution or filing of
any paper or any further act on the part of any of the parties hereto. If, at
the time such successor by merger or consolidation to the Warrant Agent shall


                                     1.91-9

succeed to the agency created by this Warrant Agreement, any of the Warrants
shall have been countersigned but not delivered, any such successor to the
Warrant Agent may adopt the countersignature of the predecessor Warrant Agent
and deliver such Warrants so countersigned; and if at that time any of the
Warrants shall not have been countersigned, any successor to the Warrant Agent
may countersign such Warrants either in the name of the predecessor Warrant
Agent or in the name of the successor Warrant Agent; and in all such cases
Warrants shall have the full force provided in the Warrants and in this Warrant
Agreement. If at any time the name of the Warrant Agent shall be changed and at
such time any of the Warrants shall have been countersigned but not delivered,
the Warrant Agent may adopt the countersignatures under its prior name and
deliver such Warrants so countersigned; and if at that time any of the Warrants
shall not have been countersigned as provided in Section 3.4, the Warrant Agent
may countersign such Warrants either in its prior name or in its changed name;
and in all such cases such Warrants shall have the full force provided in the
Warrants and in this Warrant Agreement.

           13.2 Certain Terms and Conditions Concerning the Warrant Agent. The
Warrant Agent undertakes the duties and obligations imposed by this Warrant
Agreement upon the following terms and conditions, by all of which the Company
and the Holders, by their acceptance of Warrants, shall be bound:

               (a) Correctness of Statements. The statements contained herein
and in the Warrants shall be taken as statements of the Company, and the Warrant
Agent assumes no responsibility for the correctness of any of the same. The
Warrant Agent assumes no responsibility with respect to the distribution of the
Warrants except as herein expressly provided.

               (b) Breach of Covenants. The Warrant Agent shall not be
responsible for any failure of the Company to comply with any of the covenants
contained in this Warrant Agreement or in the Warrants to be complied with
specifically by the Company.

               (c) Performance of Duties. The Warrant Agent may execute and
exercise any of the rights or powers hereby vested in it or perform any duty
hereunder either itself or by or through its attorneys or agents (which shall
not include its employees) and shall not be responsible for the misconduct or
negligence of any agent appointed with due care.

               (d) Reliance on Counsel. The Warrant Agent may consult at any
time with legal counsel satisfactory to it, and the Warrant Agent shall incur no
liability or responsibility to the Company or to any Holder in respect of any
action taken, suffered or omitted by it hereunder in good faith and in
accordance with the opinion or the advice of such counsel provided that such
counsel shall have been selected with due care.

               (e) Proof of Actions Taken. Whenever in the performance of its
duties under this Warrant Agreement the Warrant Agent shall deem it necessary or
desirable that any fact or matter be proved or established by the Company prior
to taking or suffering any action hereunder, such fact or matter (unless other
evidence in respect thereof be herein specifically prescribed) may be deemed
conclusively to be proved and established by a certificate signed by the
President, a Vice President, the Secretary or an Assistant Secretary of the


                                    1.91-10

Company and delivered to the Warrant Agent; and such certificate shall be full
authorization to the Warrant Agent for any action taken or suffered in good
faith by it under the provisions of this Warrant Agreement in reliance upon such
certificate.

               (f) Legal Proceedings. The Warrant Agent shall be under no
obligation to institute any action, suit or legal proceeding or to take any
other action likely to involve expense unless the Company or one or more Holders
shall furnish the Warrant Agent with reasonable security and indemnity for any
costs and expenses that may be incurred, but this provision shall not affect the
power of the Warrant Agent to take such action as the Warrant Agent may consider
proper, whether with or without any such security or indemnity. All rights of
action under this Warrant Agreement or under any of the Warrants may be enforced
by the Warrant Agent without the possession of any of the Warrants or the
production thereof at any trial or other proceeding relative thereto, and any
such action, suit or proceeding instituted by the Warrant Agent shall be brought
in its name as Warrant Agent, and any recovery of judgment shall be for the
ratable benefit of the Holders, as their respective rights or interests may
appear.

               (g) Other Transactions in Securities of the Company. [The Warrant
Agent and any stockholder, director, officer or employee of the Warrant Agent
may buy, sell or deal in any of the Warrants or other securities of the Company
or become pecuniarily interested in any transaction in which the Company may be
interested, or contract with or lend money to the Company or otherwise act as
fully and freely as though it were not Warrant Agent under this Warrant
Agreement.] Nothing herein shall preclude the Warrant Agent from acting in any
other capacity for the Company or for any other legal entity.

               (h) Liability of Warrant Agent. The Warrant Agent shall act
hereunder solely as agent, and its duties shall be determined solely by the
provisions hereof. The Warrant Agent shall not be liable for anything that it
may do or refrain from doing in connection with this Warrant Agreement except
for its own gross negligence or bad faith.

               (i) Reliance on Documents. The Warrant Agent will not incur any
liability or responsibility to the Company or to any Holder for any action taken
in reliance on any notice, resolution, waiver, consent, order, certificate, or
other paper, document or instrument reasonably believed by it to be genuine and
to have been signed, sent or presented by the proper party or parties.

               (j) Validity of Agreements. The Warrant Agent shall not be under
any responsibility in respect of the validity of this Warrant Agreement or the
execution and delivery hereof (except the due execution and delivery hereof by
the Warrant Agent) or in respect of the validity or execution of any Warrant
(except its countersignature and delivery thereof); nor shall the Warrant Agent
by any act hereunder be deemed to make any representation or warranty as to the
authorization or reservation of any Common Stock (or other stock or other
property) to be issued pursuant to this Warrant Agreement or any Warrant, or as
to whether any Common Stock (or other stock or other property) will, when
issued, be validly issued, fully paid and nonassessable, or as to the Warrant
Price or the number or amount of Common Stock or other securities or other
property issued upon exercise of any Warrant.


                                    1.91-11

               (k) Instructions from Company. The Warrant Agent is hereby
authorized and directed to accept instructions with respect to the performance
of its duties hereunder from the President, a Vice President, the Secretary or
any Assistant Secretary of the Company, and to apply to such officers for advice
or instructions in connection with its duties, and shall not be liable for any
action taken or suffered to be taken by it in good faith in accordance with
instructions of any such officer or officers.

           13.3 Change of Warrant Agent. The Warrant Agent may resign and be
discharged from its duties under this Warrant Agreement by giving to the Company
30 days' advance notice in writing. The Warrant Agent may be removed by like
notice to the Warrant Agent from the Company. If the Warrant Agent shall resign
or be removed or shall otherwise become incapable of acting, the Company shall
appoint a successor to the Warrant Agent. If the Company shall fail to make such
appointment within a period of 30 days after such removal or after it has been
notified in writing of such resignation or incapacity by the resigning or
incapacitated Warrant Agent, then any Holder may apply to a court of competent
jurisdiction for the appointment of a successor to the Warrant Agent. Pending
the appointment of the successor warrant agent, the Company shall perform the
duties of the Warrant Agent. After appointment, the successor warrant agent
shall be vested with the same powers, rights, duties and responsibilities as if
it had been originally named as Warrant Agent without further act or deed;
provided, however, the former Warrant Agent shall be required to deliver and
transfer to the successor warrant agent any property at the time held by it
hereunder, and execute and deliver any further assurance, conveyance, act or
deed necessary for the purpose. Failure to file any notice provided for in this
Section 13.3, however, or any defect therein, shall not affect the legality or
validity of the resignation or removal of the Warrant Agent or the appointment
of the successor warrant agent, as the case may be. In the event of such
resignation or removal, the successor warrant agent shall mail, first class, to
each Holder, written notice of such removal or resignation and the name and
address of such successor warrant agent.

           13.4 Disposition of Proceeds on Exercise of Warrants; Inspection of
Warrant Agreement. The Warrant Agent shall account promptly to the Company with
respect to Warrants exercised and concurrently pay to the Company in immediately
available funds all amounts received by the Warrant Agent for the purchase of
the Warrant Stock through the exercise of such Warrants. The Warrant Agent
shall, upon request of the Company from time to time, deliver to the Company
such complete reports of registered ownership of the Warrants and such complete
records of transactions with respect to the Warrants as the Company may request.
The Warrant Agent shall also make available to the Company for inspection by the
Company's agents or employees, from time to time as the Company may request,
such original books of accounts and records maintained by the Warrant Agent in
connection with the issuance and exercise of Warrants hereunder, such
inspections to occur at the Warrant Agent's Principal Office. The Warrant Agent
shall keep copies of this Warrant Agreement and any notices given or received
hereunder available for inspection by the Company or the Holders at the Warrant
Agent's Principal Office. The Company shall supply the Warrant Agent from time
to time with such numbers of copies of this Warrant Agreement as the Warrant
Agent may request.

           13.5 Cancellation. The Warrant Agent shall cancel all Warrant
certificates properly surrendered for exercise, exchange, substitution, or
transfer. The Warrant Agent shall destroy all cancelled Warrant certificates
and, if requested, deliver a certificate of such destruction to the Company.


                                    1.91-12

Warrant Agreement shall inure to the benefit of each Holder from time to time of
Warrants.

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

                    [Form of Reverse of Warrant Certificate]

           The Warrants evidenced by this Warrant Certificate are part of a duly
authorized issue of up to [_________] Warrants expiring at 5:00 p.m., New York
City time, on the Expiration Date, entitling the Holder, on exercise, to
purchase shares of Common Stock, par value [$____] per share, of the Company,
and are issued or to be issued pursuant to the Warrant Agreement, which Warrant
Agreement is hereby incorporated by reference and made a part of this instrument
and is hereby referred to for a description of the rights, limitation of rights,
obligations, duties and immunities thereunder of the Warrant Agent, the Company
and the Holders. A copy of the Warrant Agreement may be obtained by the Holder
hereof upon written request to the Company or the Warrant Agent at the addresses
set forth below.

           Warrants may be exercised by surrendering this Warrant Certificate,
with the Election to Purchase set forth hereon properly completed and executed,
together with payment of the purchase price by certified or official bank check
payable to the order of the Warrant Agent for the account of the Company. In the
event that the number of Warrants exercised shall be less than the total number
of Warrants evidenced hereby, there shall be issued to the Holder hereof or the
Holder's assignee a new Warrant Certificate evidencing the number of Warrants
not exercised.

           The Warrant Agreement provides that the number of shares of Common
