                  5% CONVERTIBLE DEBENTURE DUE APRIL 30, 2002

     THIS DEBENTURE is one of a duly authorized issue of debentures of YES!
Entertainment Corporation, a corporation organized and existing under the laws
of Delaware and having a principal place of business at 3875 Hopyard Road, Suite
375, Pleasanton, California 94588 (the "Company"), designated as its 5%
Convertible Debentures, due April 30, 2002 (the "Debentures"), in an aggregate
principal amount of $[                ].  This Debenture supersedes in its
entirety the Debentures of like tenor, issued by the Company to the Holder on or
after July 25, 1997.

     FOR VALUE RECEIVED, the Company promises to pay to [                   ], 
or its registered assigns (the "Holder"), the principal sum of [            ] 
($[       ]) (together with all additional sums of deferred interest added to
the principal balance of this Debenture as provided below) on April 30, 2002 or
such earlier date as the Debentures are required to be repaid as provided
hereunder (the "Maturity Date") with interest (calculated on the basis of a 360-
day year and for the actual number of days elapsed) accruing on the unpaid
balance thereof from the date hereof at the rate of 5% per annum, payable (i) on
the last day of March, June, September and December of each year, commencing
September 30, 1998; (ii) upon conversion; or (iii) upon the Maturity Date if not
earlier converted. Accrued interest on this Debenture shall, at the Company's
option, be (i) paid in cash or (ii) added to the outstanding principal balance
of this Debenture with effect as of the day such interest is payable. Interest

                                       1

 
hereunder will be paid to the person in whose name this Debenture (or one or
more predecessor Debentures) is registered on the records of the Company
regarding registration and transfers of the Debentures (the "Debenture
Register"); provided, however, that the Company's obligation to a transferee of
this Debenture arises only if such transfer, sale or other disposition is made
in accordance with the terms and conditions hereof and of the Purchase Agreement
(as hereafter defined). All overdue amounts hereunder shall bear interest at the
rate of 15% per annum from the date such payment is due. Subject to the
foregoing, the principal of, and interest on, this Debenture are payable in such
coin or currency of the United States of America as at the time of payment is
legal tender for payment of public and private debts, at the address of the
Holder last appearing on the Debenture Register. A transfer of the right to

     SECTION 1.  The Debentures are exchangeable for an equal aggregate
principal amount of Debentures of different authorized denominations, as

exchange.

     SECTION 2.  This Debenture has been issued subject to certain investment
representations of the original Holder set forth in the Purchase Agreement and
may be transferred or exchanged only in compliance with the Securities Act,
pursuant to an effective registration statement or pursuant to an available
exemption from the registration requirements under the Securities Act.  Prior to
due presentment to the Company for transfer of this Debenture, the Company and
any agent of the Company may treat the person in whose name this Debenture is
duly registered on the Debenture Register as the owner hereof for the purpose of
receiving payment as herein provided and for all other purposes, whether or not
this Debenture is overdue, and neither the Company nor any such agent shall be
affected by notice to the contrary.

thereafter or such other cure period as may specifically be provided herein or
in such other agreements with respect to any particular covenant, agreement or
warranty;

        (c)  the Company or any of its subsidiaries shall commence a voluntary

controverted within thirty (30) days, or is not dismissed within sixty (60)
days, after commencement of such involuntary case; or a "custodian" (as defined
in the Bankruptcy Code) is appointed for, or takes charge of, all or any
substantial part of the property of the Company or the Company commences any
other proceeding under any reorganization, arrangement, adjustment of debt,

        (d)  the Company shall fail to pay any amount of principal or interest
on any mortgage, credit agreement or other facility, indenture or other
instrument under which there may be issued, or by which there may be secured or
evidenced, any indebtedness of the Company in an amount exceeding one hundred
thousand dollars ($100,000) (collectively, "Indebtedness"), whether such
Indebtedness now exists or shall hereafter be created, when and as the same
shall become due and payable, or the Company shall fail to observe or perform
any term, covenant or agreement contained in any agreement or instrument
evidencing or governing any of such Indebtedness if the cure period for such
term, covenant or agreement contained in such agreement or instrument has run
and the holder or holders of such Indebtedness or a trustee on their behalf

stated maturity;

        (e)  the Company shall dispose of all or substantially all of its assets
in one or more transactions or shall be a party to any business combination
pursuant to which the Company shall not be the surviving entity, except if, upon
the effectiveness of such a business combination, (i) the holders of the Common
Stock immediately prior to such effectiveness beneficially own (as determined
under Rule 13d-3 promulgated under the Exchange Act in the aggregate, 66 2/3% or
more of the voting power of such surviving entity and (ii) no Person or group
(as described in Rule 13d-5(b) promulgated under the Exchange Act) who was not a
holder 

                                       3

 
of the Common Stock immediately prior to such business combination beneficially

     If any Event of Default occurs and is continuing, and in every such case,
then so long as such Event of Default shall then be continuing, Holders of a
majority of the aggregate principal amount of Debentures then outstanding may,
by notice to the Company, declare the full outstanding principal amount of this
Debenture, together with all accrued but unpaid interest thereon and other
amounts owing hereunder, through the date of acceleration to be, whereupon the
same shall become, immediately due and payable without presentment, demand,
protest or other notice of any kind, all of which are waived by the Company,
notwithstanding anything herein contained to the contrary, and the Holder may
immediately and without expiration of any grace period enforce any and all of
its rights and remedies hereunder and all other remedies available to it under
applicable law.  Such declaration may be rescinded and annulled by Holder at any
time prior to payment hereunder.  No such rescission or annulment shall affect
any subsequent Event of Default or impair any right consequent thereon.

     SECTION 4.  CONVERSION.

        (a)  CONVERSION AT HOLDER'S OPTION.  This Debenture shall be convertible
in whole or in part into shares of Common Stock (as hereafter defined) (subject
to reduction pursuant to Section 4(b)) at the option of the Holder in whole or
in part at any time and from time to time and prior to 7:30 p.m. (Eastern
Standard Time) on the Maturity Date at the Conversion Ratio (as hereafter
defined), as adjusted to give effect to any and all Adjustment Events (as
hereafter defined) occurring prior to conversion. The Holder shall effect
conversions by surrendering to the Transfer Agent (as hereafter defined) the
Debentures (or such portions thereof) to be converted and to the Company and the
Transfer Agent deliver a conversion notice in the form attached hereto as
Exhibit A (the "Conversion Notice"). Each Conversion Notice shall specify the
principal amount (and the amount of accrued but unpaid interest thereon) of
Debentures to be converted and the date on which conversion is to be effected
(the "Conversion Date"), which date may not be prior to the date the Holder
delivers such Conversion Notice by facsimile. If no Conversion Date is specified
in a Conversion Notice, the Conversion Date shall be the date that the
Conversion Notice is deemed deliverable pursuant to Section 4(i). Subject to
Section 4(b), each Conversion Notice, once given, shall be irrevocable unless
the Company fails to deliver a certificate or certificates representing the
underlying Common Stock pursuant to Section 4(d) within 3 Trading Days of the
Conversion Date, at which time or any time thereafter 

                                       4

 
the holder of the Debentures may, at its option either (a) cancel the Conversion
Notice or (b) elect to have the Common Stock issuable upon conversion of this
Debenture deemed to be issued and outstanding and held as of record as of the
Conversion Date by the holder of this Debenture which sent the Conversion
Notice. If a Holder is converting less than all of the principal amount
represented by the Debentures tendered by such Holder with the Conversion
Notice, or if a conversion hereunder cannot be effected in full for any reason,
the Company shall promptly deliver to such Holder (in the manner within the time
set forth in Section 4(d)) a new Debenture for such principal amount as has not
been converted.

        (b)  CERTAIN REGULATORY APPROVAL.  (i) The Company shall have until
December 21, 1998 to obtain Stockholder Approval (as defined below) of the
issuance of Common Stock upon conversion/exercise of the Series C Preferred, the
Debentures and the Warrants (each as defined in the Purchase Agreement). In the
event the Company has not obtained such Stockholder Approval by December 21,
1998, then, unless the holder of this Debenture on such date shall have
delivered written notice to the Company that this Debenture shall not be
redeemed pursuant to this subsection (b)(i), the Company shall within five
business days thereafter repay all of the principal amount (and the amount of
accrued but unpaid interest thereon) of Debentures then outstanding at a price
equal to the Prepayment Price. If Company fails for any reason to pay the
Prepayment Price on or prior to December 23, 1998, if required, the Company will
pay interest on such Prepayment Price at a rate of 20% per annum to the Holder,
accruing from December 21, 1998 until the Prepayment Price plus any accrued
interest thereon is paid in full. The entire Prepayment Price, including
interest thereon, shall be paid in cash. "Stockholder Approval" means the
approval by a majority of the total votes cast on the proposal, in person or by
proxy, at a meeting of the stockholders of the Company held in accordance with
the Company's certificate of incorporation and by-laws, of (A) the issuance by
the Company of shares of Common Stock pursuant to the conversion/exercise of
Series C Preferred, the Debentures and the Warrants (each as defined in the
Purchase Agreement) into Common Stock as and to the extent required pursuant to
Rule 4460(i) of the Nasdaq Stock Market (or any successor or replacement
provision thereof) and (B) an increase in the authorized number of shares of
Common Stock sufficient to cause the number of authorized and unissued and
unreserved shares of Common Stock on such date to exceed by at least 10 million
shares the number of shares of Common Stock issuable upon the conversion and
exercise of all of the outstanding shares of Series B Preferred and Series C
Preferred, the July Debentures, the Debentures and the Warrants.

             (ii) If on a Conversion Date (A) the Common Stock is then listed
for trading on the Nasdaq National Market or, if the rules of the Nasdaq Stock
Market are hereafter amended to extend Rule 4460(i) promulgated thereby (or by a
successor or replacement provision thereof) to the Nasdaq SmallCap Market, on
the Nasdaq SmallCap Market, (B) the Conversion Ratio, as adjusted to give effect
to any and all Adjustment Events occurring prior to conversion, is such that the
aggregate number of shares of Common Stock that would then be issuable upon
conversion of all outstanding shares of Series C Preferred and Debentures, would
equal or exceed 20% of the number of shares of Common Stock outstanding on the
Conversion Date (the "Issuable Maximum"), and (C) the Company has not previously
obtained Stockholder 

                                       5

 
Approval, then the Company shall issue to the converting holder of this
Debenture up to the Issuable Maximum (and no more).

        (c)  AUTOMATIC CONVERSION.  If the Company shall have obtained
Stockholder Approval of the issuance of the Common Stock upon conversion of the
Debentures on or prior to December 21, 1998, then the principal amount of (and
accrued but unpaid interest thereon) any and all Debentures outstanding on April
30, 2002 (the "Automatic Conversion Date") shall be automatically converted into
fully paid and nonassessable shares of Common Stock, at the Conversion Ratio, as
adjusted to give effect to any and all prior Adjustment Events prior to
conversion, in the manner provided herein.

        (d)  DELIVERY OF CERTIFICATES.  Not later than three (3) Trading Days
after a Conversion Date or the Automatic Conversion Date, the Company shall
cause the Transfer Agent (as hereafter defined) to deliver to the Holder (i) a
certificate or certificates, representing the number of shares of Common Stock
being acquired upon the conversion of Debentures (subject to reduction pursuant
to Section 5(b)(ii)) and (ii) Debentures in a principal amount equal to the
principal amount of Debentures tendered in connection with a conversion
hereunder but not converted. Any certificates representing shares of Common
Stock to be delivered upon a conversion hereunder shall be free of restrictive
legends and trading restrictions, except those specified in Section 4.1(b) of
the Purchase Agreement. The Company shall not be obligated to issue certificates
evidencing the shares of Common Stock issuable upon conversion of any Debentures
to be converted are either delivered to the Transfer Agent for conversion, or
until the Holder notifies the Company that such Debentures have been lost,
stolen or destroyed and provides a bond reasonably satisfactory to the Company
(or other adequate security reasonably acceptable to the Company) to indemnify
the Company from any loss incurred by it in connection therewith. The Company
shall, upon request of the Holder, use its best efforts to deliver any
Debentures required to be delivered by the Company under this Section
electronically through the Depository Trust Corporation or another established
clearing corporation performing similar functions. If such certificate or
certificates are not delivered within ten (10) Trading Days after a Conversion
Date, the holder shall be entitled to rescind such Conversion Notice upon
written notice to the Company, in which event the Company shall immediately
instruct the Transfer Agent to return the Debentures subject to such Conversion
Notice that were tendered for conversion. The Company shall pay to the
converting Holder, as liquidated damages and not as penalty, $3,000 for each day
that the Company fails to deliver such certificate or certificates pursuant to
this Section commencing after the fifth (5th) Trading Day after the applicable
Conversion Date or Automatic Conversion Date. In addition, if the Company fails
to deliver to the Holder such Debentures pursuant to this Section prior to a
fifteenth (15th) day after the Conversion Date or Automatic Conversion Date, the
Company shall, at the Holder's option, repay the principal amount of (and
accrued but unpaid interest on) the Debentures then held by such Holder, as
requested by such Holder, in an amount equal to the Prepayment Price calculated
as of the Conversion Date or Automatic Conversion Date (which date may be
referred to herein as a "Prepayment Date"). If the Holder has requested that the
Company repay the Debentures pursuant to this Section and the Company fails for
any reason to pay the Prepayment Price hereunder within five (5) Business Days
after such notice, the Company will pay interest on such Prepayment Price at a
rate of 17% per annum, in cash to such 

                                       6

 
Holder, accruing from such fifth (5th) Business Day until such Prepayment Price
and any accrued but unpaid interest thereon is paid in full.

        (e)  ADJUSTMENTS.

             (i)    The following events shall be deemed to be "Adjustment
Events:"

                  A.  If the Company, at any time while any Debentures are
outstanding, (a) shall pay a stock dividend or otherwise make a distribution or
distributions on shares of its Junior Securities payable in shares of either
Common Stock or of capital stock of any class (whether payable in shares of its
Common Stock or of capital stock of any class), (b) subdivide outstanding shares
of Common Stock into a larger number of shares, or (c) combine outstanding
shares of Common Stock into a smaller number of shares.

                  B.  If the Company, at any time while any Debentures are
outstanding, shall issue rights or warrants to all Holders of Common Stock
entitling them to subscribe for or purchase shares of Common Stock at a price
per share less than the Per Share Market Price of Common Stock as calculated on
the record date.

                  C.  If the Company, at any time while any Debentures are
outstanding, shall distribute to all Holders of Common Stock (and not to the
Holders) evidences of its indebtedness or assets or rights or warrants to
subscribe for or purchase any security (excluding those referred to in Sections
4(e)(i)(A) and (i)(B) above).

             (ii)   ADJUSTMENT FOR STOCK SPLITS, COMBINATIONS.  If an Adjustment
Event described in 4(e)(i)(A) occurs, then the Conversion Ratio, as adjusted to
give effect to all prior Adjustment Events, shall be multiplied by a fraction,
the numerator of which shall be the number of shares of Common Stock outstanding
before such event and the denominator of which shall be the number of shares of
Common Stock outstanding after such event. Any adjustment computed pursuant to
this Section 4(e)(ii) shall become effective immediately after the record date
for the determination of stockholders entitled to receive such dividend or
distribution and shall become effective immediately after the effective date in
the case of a subdivision or combination.

             (iii)  ADJUSTMENT FOR ISSUANCES TO COMMON STOCKHOLDERS.  If an
Adjustment Event described in 4(e)(i)(B) occurs, then Conversion Ratio, as
adjusted to give effect to all prior Adjustment Events, shall be multiplied by a
fraction, the numerator of which shall be the number of shares of Common Stock
(excluding treasury shares, if any, but including warrants or options that would
be included for purposes of determining earnings per share in accordance with
generally accepted accounting principles) outstanding on the date of issuance of
such rights or warrants plus the number of shares which the aggregate offering
price of the total number of shares so offered would purchase at such Per Share
Market Price, and the denominator of which shall be the number of shares of
Common Stock (excluding treasury shares, if any, but including warrants or
options that would be included for purposes of determining earnings per share in
accordance with generally accepted accounting principles) outstanding on the
date of issuance of such rights or warrants plus the number of additional shares
of Common Stock 

                                       7

 
offered for subscription or purchase. Such adjustment shall be calculated
whenever such rights or warrants are issued, and shall become effective
immediately after the record date for the determination of stockholders entitled
to receive such rights or warrants. However, upon the expiration of any right or
warrant to purchase Common Stock the issuance of which resulted in an adjustment
pursuant to this Section 4(e)(iii), if any such right or warrant shall expire
and shall not have been exercised, such adjustment shall immediately upon such
expiration be recomputed as if the adjustment calculated upon the issuance of
such rights or warrants been calculated on the basis of offering for
subscription or purchase only that number of shares of Common Stock actually
purchased upon the exercise of such rights or warrants actually exercised.

             (iv)   ADJUSTMENT FOR DISTRIBUTION OF EVIDENCES OF INDEBTEDNESS OR
ASSETS TO COMMON STOCKHOLDERS. If an Adjustment Event described in 4(e)(i)(C)
occurs, then the Conversion Ratio, as adjusted to give effect to all prior
Adjustment Events, shall be multiplied by a fraction the numerator of which
shall be such Per Share Market Price on such record date less the then fair
market value at such record date of the portion of such assets or evidence of
indebtedness so distributed applicable to one outstanding share of Common Stock
as determined by the Board of Directors in good faith, and the denominator of
which shall be the Per Share Market Price determined as of such record date;
provided, however, that in the event of a distribution exceeding ten percent
(10%) of the net assets of the Company, such fair market value shall be
determined by a nationally recognized or major regional investment banking firm
or firm of independent certified public accountants of recognized standing
(which may be the firm that regularly examines the financial statements of the
Company) (an "Appraiser") selected in good faith by the Holders; and provided,
further, that the Company, after receipt of the determination by such Appraiser
shall have the right to select an additional Appraiser, in good faith, in which
case the fair market value shall be equal to the average of the determinations
by each such Appraiser. Such adjustment shall be calculated whenever any such
distribution is made and shall become applicable immediately after the record
date mentioned above.

             (v)    Upon the occurrence of an Adjustment Event, the Company
shall promptly to mail to each Holder a notice setting forth (a) the adjustment
to the Conversion Ratio required by the Adjustment Event at issue, (b) the
cumulative adjustment to which the Conversion Ratio shall be subject after the
Adjustment Event, giving effect to any and all prior Adjustment Events, and (c)
a brief statement of the facts requiring the adjustment at issue.

             (vi)   ROUNDING.  All calculations under this Section 4 shall be
made to the nearest cent or the nearest 1/100th of a share, as the case may be.

             (vii)  RECLASSIFICATIONS OR SHARE EXCHANGE.  In case of any
reclassification of the Common Stock or any compulsory share exchange pursuant
to which the Common Stock is converted into other securities, cash or property,
the Holder shall have the right thereafter to, at their option, (A) convert the
principal amount of (and accrued but unpaid interest on) this Debenture into the
shares of stock and other securities, cash and property receivable upon or
deemed to be held by holders of Common Stock following such reclassification or
compulsory share exchange, and the Holder shall be entitled upon such event to
receive such amount of securities or property as the shares of the Common Stock
of the 

                                       8

 
Company into which the principal amount (and accrued and unpaid interest
thereon) of the Debentures could have been converted immediately prior to such
event or (B) require the Company to repay the principal amount (and all accrued
and unpaid interest thereon) of the Debentures.

             (viii) CERTAIN EVENTS.  The Company shall not effect any of the
following actions prior to obtaining Stockholder Approval of the issuance of the
Common Stock upon conversion of the Debentures:

                   A.  declare a dividend (or any other distribution) on its
Common Stock (other than a subdivision of the outstanding shares of Common
Stock); or

                   B.  declare a special nonrecurring cash dividend on or
authorize a repurchase or redemption of more than ten thousand (10,000) shares
of its then outstanding Common Stock, other than a repurchase or redemption of
the Common Stock of an employee upon termination of employment with the Company
for any reason; or

                   C.  authorize the granting to all Holders of the Common Stock
rights or warrants to subscribe for or purchase any shares of capital stock of
any class or of any rights; or

                   D.  any reclassification of the Common Stock (other than a
subdivision or combination of then outstanding shares of Common Stock), any
consolidation or merger to which the Company is a party, any sale or transfer of
all or substantially all of the assets of the Company, or any compulsory share
exchange whereby the Common Stock is converted into other securities, cash or
property; or

                   E.  authorize the voluntary or involuntary dissolution,
liquidation or winding up of the affairs of the Company.

     After obtaining such Stockholder Approval, in the event any of the
foregoing actions occur, then the Company shall cause to be filed at each office
or agency maintained for the purpose of conversion of Debentures and shall cause
to be mailed to the Holders at its last addresses as shall appear on the
Debenture Register, at least thirty (30) calendar days prior to the applicable
record or effective date hereinafter specified, a notice stating (x) the date on
which a record is to be taken for the purpose of such dividend, distribution,
redemption, rights or warrants, or if a record is not to be taken, the date as
of which the Holders of Common Stock of record to be entitled to such dividend,
distributions, redemption, rights or warrants are to be determined or (y) the
date on which such reclassification, consolidation, merger, sale, transfer,
share exchange, dissolution, liquidation or winding-up is expected to become
effective, and the date as of which it is expected that Holders of Common Stock
of record shall be entitled to exchange their shares of Common Stock for
securities, cash, or other property deliverable upon such reclassification,
consolidation, merger, sale, transfer, share exchange, dissolution, liquidation
or winding-up; provided, however, that the failure to mail such notice or any
defect therein or in the mailing thereof shall not affect the validity of the
corporate action required to be specified in such notice.

                                       9

 
        (f)  RESERVATION OF COMMON STOCK.  The Company covenants, from and after
obtaining Stockholder Approval, that it shall at all times reserve and keep
available out of its authorized and unissued Common Stock solely for the purpose
of issuance upon conversion of Debentures, as herein provided, free from
preemptive rights or any other actual contingent purchase rights of persons
other than the Holder, such number of shares of Common Stock as shall be

issued and fully paid and nonassessable.

        (g)  FRACTIONAL SHARES.  Upon a conversion hereunder the Company shall
not be required to issue stock certificates representing fractions of shares of

Holder shall be entitled to receive, in lieu of the final fraction of a share,
one whole share of Common Stock.

Stock on conversion of Debentures shall be made without charge to the Holders
thereof for any documentary stamp or similar taxes that may be payable in

shall not be required to pay any tax that may be payable in respect of any
transfer involved in the issuance and delivery of any such certificate upon
conversion in a name other than that of the Holder.

        (i)  NOTICE.  Any and all notices or other communications or deliveries
to be provided by the Holder hereunder, including, without limitation, any
Holder Conversion Notice, shall be in writing and delivered personally, by
facsimile, sent by a nationally recognized overnight courier service or sent by

     SECTION 5.  PREPAYMENT BY THE COMPANY.

        (a)  OPTIONAL PREPAYMENT BY COMPANY.

             (i)    The Company shall have the right, exercisable at any time
after or concurrent with such time as all shares of Series B Preferred have been
converted or redeemed upon fifteen (15) Trading Days notice to the Holders (the
"Optional Prepayment Notice"), to prepay all of the principal amount of the
Debentures then outstanding at the Prepayment Price calculated on the date of
the Optional Prepayment Notice (which date may be referred to herein as a
"Prepayment Date"); provided, however, that the Company shall not redeem the
Debentures from a holder without simultaneously repaying any and all
indebtedness owed to such holder of Debentures. The entire Prepayment Price
shall be paid in cash.

             (ii)   The holders of the Debentures shall have until the
Redemption Date to convert any and all Debentures into shares of Common Stock by
delivering a Conversion Notice on or prior to the date that is the business day
before the Redemption Date. On or after the Prepayment Date, no Holder shall
have the right to continue to convert Debentures which have been noticed for
redemption.

             (iii)  On or before the fifth Trading Day after the Optional
Prepayment Date, the Holder shall deliver to the Company the Debentures subject
to the Optional Prepayment Notice that have not been previously tendered for
conversion and the Company shall deliver a sum equal to the Prepayment Price as
calculated on the Prepayment Date. 

             (iv)   Notwithstanding the other provisions of this Section 5, in
the event the Company effects a merger, redemption, consolidation,
recapitalization, sale of all or substantially all of its assets or other
business combination within 90 days of the Redemption Date and the Redemption
Price is less than the consideration that the Holders of the Debentures would
have received upon conversion of the Debentures into Common Stock pursuant to
such subsequent Event (the "Subsequent Consideration") then, prior to or
concurrently with such transaction the Company shall pay to the former holders
of the Debentures that were redeemed on the Redemption Date the difference
between the Subsequent Consideration and the Redemption Price.

        (b)  LIQUIDATED DAMAGES.  If the Optional Prepayment Price shall not be
paid in full on or before the fifteenth Trading Day after the Prepayment Date,
the Company shall pay to the holders of Debentures subject to Redemption as
liquidated damages and not as a penalty the sum of seven thousand five hundred
dollars ($7,500) per day in cash until such Optional Prepayment Price, together
with all such liquidated damages, is paid in full. In addition, if the Company
shall have failed to pay any portion of the Optional Prepayment Price on or
before the eighteenth Trading Day after the Prepayment Date, then the Holder may
demand that the Company (i) convert all or any portion of the principal amount
of the Debentures for which the Optional Prepayment Price shall not have been
paid (the "Unpaid Principal Portion") at a Conversion Price calculated as at the
date of the Optional Prepayment Notice or the date of such conversion, whichever
is lower, or (ii) promptly issue to the Holders new Debentures for a principal
amount equal to the Unpaid Principal Portion.

                                       11

 
        (c)  BNY CONSENTS.  Notwithstanding anything to the contrary contained
herein, so long as the BNY Bank Obligations are outstanding, the Company shall
not deliver an Optional Prepayment Notice unless (i) there are no outstanding
Debentures or all outstanding Debentures are subject to a delivered redemption
notice and (ii) it has received (and furnished to the Holder evidence thereof
reasonably satisfactory to it or) prior written consent of BNY to make such
prepayment free from the subordination provisions of Section 8 hereof.

of such payment shall not cause (as determined at the time such payment shall
become due to the Holders) an Event of Default under such Receivables Agreement
sections set forth in (ii) immediately above or cause the Company to exceed the
borrowing limitations set forth in Section 2 of the Receivables Agreement. The

convert Debentures into shares of Common Stock and to receive payment of
interest hereunder in shares of Common Stock, including after such time as any
Event of Default shall be declared hereunder.

        (b)  Should any payment, other than payments contemplated in Section

the Holders for the benefit of BNY and shall be delivered forthwith to BNY for
application to BNY Bank Obligations, in the form received with any necessary

to vote, to receive dividends and other distributions, or to receive any notice
of, or to attend, meetings of stockholders or any other proceedings of the
Company, unless and to the extent converted into shares of Common Stock in
accordance with the terms hereof.

     SECTION 10.  If this Debenture shall be mutilated, lost, stolen or
destroyed, the Company shall execute and deliver, in exchange and substitution
for and upon cancellation of a mutilated Debenture, or in lieu of or in
substitution for a lost, stolen or destroyed debenture, a new Debenture for the
principal amount of this Debenture so mutilated, lost, stolen or destroyed but
only upon receipt of evidence of such loss, theft or destruction of such
Debenture, and of the ownership hereof, and indemnity, if requested, all
reasonably satisfactory to the Company.

     SECTION 11.  This Debenture shall be governed by and construed in
accordance with the laws of the State of New York, without giving effect to
conflicts of laws thereof.

     SECTION 12.  Any waiver by the Company or the Holder of a breach of any
provision of this Debenture shall not operate as or be construed to be a waiver
of any other breach of such provision or of any breach of any other provision of
this Debenture.  The failure of the Company or the Holder to insist upon strict
adherence to any term of this Debenture on one or more occasions shall not be
considered a waiver or deprive that party of the right thereafter to insist upon
strict adherence to that term or any other term of this Debenture.  Any waiver
must be in writing.

     SECTION 13.  If any provision of this Debenture is invalid, illegal or
unenforceable, the balance of this Debenture shall remain in effect, and if any
provision is inapplicable to any person or circumstance, it shall nevertheless
remain applicable to all other persons and circumstances.

     SECTION 14.  Whenever any payment or other obligation hereunder shall be
due on a day other than a Business Day, such payment shall be made on the next
succeeding Business Day (or, if such next succeeding Business Day falls in the
next calendar month, the preceding Business Day in the appropriate calendar
month).
