                       AMENDMENT NO. 1 AND CONSENT NO. 1
                         TO REVOLVING CREDIT AGREEMENT

     AMENDMENT NO. 1 AND CONSENT NO. 1 (this "Amendment and Consent"), dated as
of January 26, 2004, to the REVOLVING CREDIT AGREEMENT, dated as of August 20,
2003, by and among HAIGHTS CROSS OPERATING COMPANY (the "Borrower"), the several
lenders from time to time parties thereto (the "Lenders"), BEAR STEARNS
CORPORATE LENDING, INC., as Syndication Agent (in such capacity, the
"Syndication Agent"), and THE BANK OF NEW YORK ("BNY"), as administrative agent
for the Lenders (in such capacity, the "Administrative Agent") (as amended from
time to time, the "Credit Agreement").

                                    RECITALS

     I.  Unless defined herein, all capitalized terms used herein shall have the
meanings ascribed to them in the Credit Agreement.

     II.  The Borrower has advised the Administrative Agent and the Lenders that
Holdings and Bear, Stearns & Co. Inc. ("Bear Stearns") intend to enter into a
Purchase Agreement (the "Purchase Agreement"), pursuant to which Holdings would
agree to issue Senior Discount Notes due 2011 in an aggregate principal amount
at maturity of up to $135,000,000 (the "Initial Notes"), and which would be
issued by Holdings pursuant to an Indenture (the "Indenture"), between Holdings
and Wells Fargo Bank Minnesota, N.A., or another qualified trustee as Trustee
(the "Trustee"). The Borrower has advised the Administrative Agent and the
Lenders that the Initial Notes, the Exchange Notes (as defined below) and the
Indenture would have restrictive covenants and other terms (other than pricing
terms) substantially as described in the preliminary offering memorandum
relating to the proposed offering (the "Preliminary Offering Memorandum").

     III.  The holders (including subsequent transferees) of the Initial Notes
would have registration rights substantially as described in the Preliminary
Offering Memorandum pursuant to which Holdings would agree to file with the
Securities and Exchange Commission (the "Commission"), under the circumstances
set forth therein, (a) a registration statement under the Securities Act (the
"Exchange Offer Registration Statement") relating to Holdings' Senior Discount
Notes due 2011 with terms substantially identical to the Initial Notes (the
"Exchange Notes") to be offered in exchange for the Initial Notes (the "Exchange
Offer") and (b) under certain circumstances, a shelf registration statement
pursuant to Rule 415 under the Act (the "Shelf Registration Statement") relating
to the resale by certain holders of the Initial Notes. The Initial Notes and the
Exchange Notes are collectively referred to as the "Holdings Notes" and,
together with the Indenture, are collectively referred to as the "Operative
Documents."

     IV.  The incurrence by Holdings of the Indebtedness under the Operative
Documents would constitute an Event of Default under Section 8(l) of the Credit
Agreement unless the Required Lenders consent thereto.

     V.  The Borrower has requested that the Administrative Agent and the
Required Lenders (a) consent to the incurrence by Holdings of the Indebtedness
under the Operative Documents and (b) agree that the incurrence of such
Indebtedness shall not constitute an Event of Default.

     VI.  The Administrative Agent and the Required Lenders have agreed to the
Borrower's request on the terms and subject to the conditions set forth in this
Amendment and Consent.

2.       INTEREST.

         (a)      Interest Accrual. This Debenture shall bear interest on the
unpaid principal amount hereof ("Interest") at an annual rate equal to six and
one-half percent (6.5%), computed on the basis of a 365-day year and calculated
using the actual number of days elapsed since the Closing Date or the day on
which Interest was most recently paid, as the case may be, and if not timely
paid as provided herein, compounded quarterly on each Scheduled Interest Payment
Date. The Company shall pay accrued and unpaid Interest (i) on each Scheduled
Interest Payment Date, (ii) on the Maturity Date and (iii) on any date on which
the entire principal amount of this Debenture is paid in full (whether through
conversion, redemption or otherwise) (each of (i), (ii) and (iii) being referred
to herein as an "Interest Payment Date"). Any amount of Interest that is not
paid on the relevant Interest Payment Date shall bear interest at the Default
Interest Rate. The Company must pay interest at the Default Interest Rate in
cash on or before the fifth (5th) Business Day following the last day of each
calendar month in which such interest accrues.

         (b)      Stock Payment Option. At the option (the "Stock Payment
Option") of the Company and except as provided below with respect to the payment
of cash in respect of fractional shares, Interest payable on any Scheduled
Interest Payment Date may be paid, instead of in cash, in whole or in part, in

conditions (the "Stock Payment Conditions") have been satisfied from the date on
which the Interest Payment Exercise Notice is delivered through and including
the applicable Scheduled Interest Payment Date:

                  (i)      the number of shares of Common Stock authorized,
unissued and unreserved for all other purposes, or held in the Company's
treasury, is sufficient to pay the sum of (1) the number of Conversion Shares
issuable upon the conversion in full of the Debentures (without regard to any
limitation on such conversion) plus (2) the number of Warrant Shares issuable
upon the exercise in full of the Warrants (without

                                       3
<PAGE>

regard to any limitation on such exercise) plus (3) the number of Interest
Payment Shares issuable pursuant to the exercise of the Stock Payment Option;

                  (ii)     the Common Stock is authorized for quotation on the
Nasdaq SmallCap Market or Nasdaq National Market or listed on the New York Stock
Exchange;

                  (iii)    the Registration Statement is effective and available
for the resale of the Interest Payment Shares by Holder or such shares are
eligible for resale to the public pursuant to Rule 144(k) under the Securities
Act of 1933, as amended (the "Securities Act");

                  (iv)     an Event of Default (as defined below) has not
occurred and is not continuing, and no event has occurred that with the giving
of notice or passage of time, or both, would constitute an Event of Default; and

                  (v)      Shareholder Approval shall have been obtained and the
issuance of such Interest Payment Shares would not violate Section 3(h) of this
Debenture.

To the extent the Company elects to pay Interest in Interest Payment Shares,
such Interest Payment Shares shall be in an amount equal to the aggregate amount
of Interest due and payable on the applicable Scheduled Interest Payment Date
divided by the applicable Interest Payment Share Price. For purposes hereof,
"Interest Payment Share Price" with respect to a particular Scheduled Interest
Payment Date means (x) the Interest Payment Closing Price for such Scheduled
Interest Payment Date times (y) ninety five percent (95%).

         (c)      Exercise of Stock Payment Option. In order for the Company to
exercise the Stock Payment Option with respect to a Scheduled Interest Payment
Date, it must deliver written notice thereof (an "Interest Payment Exercise
Notice") to Holder on or before the tenth (10th) Business Day prior to such
Scheduled Interest Payment Date. Upon delivering an Interest Payment Exercise
Notice to Holder, the Company thereafter shall be irrevocably bound by its
election made therein, subject to the satisfaction (or waiver by Holder in its
sole and absolute discretion) of the Stock Payment Conditions, to deliver
Interest Payment Shares on the applicable Scheduled Interest Payment Share
Delivery Date (as defined below). In the event that the Company does not deliver
an Interest Payment Exercise Notice within the time frame specified in the first
sentence of this paragraph (c), or if the Stock Payment Conditions are not
satisfied as of the relevant Scheduled Interest Payment Date, the Company shall
pay the Interest due on such Scheduled Interest Payment Date in cash (unless
Holder, in its sole and absolute discretion, requests such payment be made in
Interest Payment Shares).

         (d)      Delivery of Interest Payment Shares. Upon exercise of the
Stock Payment Option and satisfaction (or waiver by Holder in its sole and
absolute discretion) of the Stock Option Payment Conditions, the Company shall
deliver to Holder, on or before the third (3rd) Business Day following the
applicable Scheduled Interest Payment Date (the "Scheduled Interest Payment
Share Delivery Date"), the aggregate number of whole Interest Payment Shares
that is issuable to Holder on such Scheduled Interest Payment Date. Holder shall
be treated for all purposes as the record holder of Interest Payment Shares as
of the Interest Payment Share Delivery Date for such Interest Payment Shares.
The Company shall effect delivery of Interest Payment Shares to Holder by, as
long as the Company's transfer agent ("Transfer Agent") is participating in the
Depository Trust Company ("DTC") Fast Automated Securities Transfer program
("FAST"), crediting the account of Holder or its nominee at DTC with the number
of Interest Payment Shares required to be delivered, no later than the close of
business on such Interest Payment Share Delivery Date. In the event that the
Transfer Agent is not a participant in FAST as of the applicable Interest
Payment Share Delivery Date, or if Holder notifies the Company in writing prior
to the applicable Scheduled Interest Payment Date that Holder wishes to receive
physical certificates, the Company shall effect delivery of Interest Payment
Shares by delivering to Holder or its nominee physical certificates representing
such Interest Payment Shares, no later than the close of

                                       4
<PAGE>
business on such Interest Payment Share Delivery Date. No fractional Interest
Payment Shares shall be issued; the Company shall, in lieu thereof, either issue
a number of Interest Payment Shares which reflects a rounding up to the next
whole number of shares or pay such amount in cash. Interest Payment Shares shall
be fully paid and non-assessable, free and clear of any liens, claims,
preemptive rights or encumbrances imposed by or through the Company. Interest
Payment Shares delivered to Holder shall not contain any restrictive legend as
long as the resale of such Interest Payment Shares (A) is covered by an
effective Registration Statement, (B) has been made pursuant to Rule 144 under
the Securities Act, or (C) may be made pursuant to Rule 144(k) under the
Securities Act or any successor rule or provision.

         (e)      Stock Payment Option Default. In the event that the Company
fails for any reason to deliver to Holder certificates representing the
appropriate number of Interest Payment Shares on or before the Interest Payment
Share Delivery Date therefor (a "Stock Payment Option Default"), and such
failure continues for three (3) Business Days following delivery of a written
notice of such failure by Holder to the Company, the Company shall pay to Holder
payments in the amount of (i) (N/365) multiplied by (ii) the amount of the
Interest payable on the applicable Scheduled Interest Payment Date multiplied by
(iii) the Default Interest Rate, where "N" equals the number of days elapsed
between the original Interest Payment Share Delivery Date for such Interest
Payment Shares and the date on which all of the certificates representing such
Interest Payment Shares are issued and delivered to Holder. Amounts payable
under this paragraph (e) shall be paid to Holder in immediately available funds
on or before the fifth (5th) Business Day of the calendar month immediately
following the calendar month in which such amounts have accrued.

         (f)      Remedies. Nothing herein shall limit Holder's right to pursue
actual damages for the Company's failure to issue and deliver Interest Payment
Shares on the applicable Interest Payment Share Delivery Date (including,
without limitation, damages relating to any purchase of Common Stock by Holder
to make delivery on a sale effected in anticipation of receiving Interest
Payment Shares upon the Company's exercise of the Stock Payment Option, such
damages to be in an amount equal to (i) the aggregate amount paid by Holder for
the Common Stock so purchased minus (ii) the aggregate amount of net proceeds,
if any, received by Holder from the sale of the Interest Payment Shares issued
by the Company pursuant to the exercise of such Stock Payment Option), and
Holder shall have the right to pursue all remedies available to it at law or in
equity (including, without limitation, a decree of specific performance and/or
injunctive relief); provided, however, that, in the event, following a Stock
Payment Option Default, the Company delivers to Holder the Interest Payment
Shares that are required to be issued by the Company pursuant to the exercise of
such Stock Payment Option, Holder shall use commercially reasonable efforts to
sell such shares promptly following such delivery.

3.       CONVERSION.

         (a)      Right to Convert. This Debenture shall be convertible, at the
option of Holder, at any time and from time to time on or after the Closing Date
until the Maturity Date, into such number of fully paid and non-assessable
Conversion Shares as is determined by dividing the amount of this Debenture that
Holder elects to convert by the Conversion Price in effect at the time of
conversion. The amount being converted shall be applied first to accrued and
unpaid Interest and the remainder shall be applied to the payment of principal
of this Debenture. Without limiting the availability of all rights and remedies
provided to it hereunder and under each Transaction Document, Holder shall not
be entitled to any additional consideration from the Company (other than shares
of Common Stock) with respect to the portion of this Debenture being converted
under this Section 3 and provided that there is no Conversion Default with
respect thereto.

         (b)      Mechanics Of Conversion. In order to convert this Debenture,
Holder shall send by facsimile transmission, at any time prior to 6:00 p.m.,
eastern time, on the Business Day on which Holder wishes to effect such
conversion (the "Conversion Date"), a notice of conversion to the Company, in
the form set forth

                                       5
<PAGE>

on Annex I hereto, stating the amount of this Debenture to be converted and a
calculation of the number of shares of Common Stock issuable upon such
conversion (a "Conversion Notice"). Holder shall thereafter send the original of
the Conversion Notice to the Transfer Agent. Holder shall not be required to
physically surrender this Debenture to the Company in order to effect a
conversion. The conversion shall be deemed to be effected as of the close of
business on the Conversion Date, and Holder shall be treated on such date for
all purposes as the record holder of the Conversion Shares issuable upon such
conversion. The Company shall maintain a record showing, at any given time, the
unpaid principal amount of this Debenture and the date of each conversion or
other payment of principal hereof made in accordance with the terms of this
Debenture. Holder shall amend Annex II hereto upon any such conversion or
payment of principal to reflect the unpaid principal amount hereof. In the case
of a dispute as to the calculation of the Conversion Price or the number of
Conversion Shares issuable upon a conversion, the Company shall promptly issue
to Holder the number of Conversion Shares that are not disputed and shall submit
the disputed calculations to its independent accountants within three (3)
Business Days of receipt of Holder's Conversion Notice. The Company shall cause
such accountant to calculate the Conversion Price as provided herein and to
notify the Company and Holder of the results in writing no later than three (3)
Business Days following the day on which such accountant received the disputed
calculations (the "Dispute Procedure"). Such accountant's calculation shall be
deemed conclusive absent manifest error. The fees of any such accountant shall
be borne by the party whose calculations are most at variance with those of such
accountant.

         (c)      Delivery of Common Stock Upon Conversion. Upon receipt of a
fax copy of a Conversion Notice from Holder, the Company shall, no later than
the close of business on the third (3rd) Business Day following the Conversion
Date set forth in such Conversion Notice (the "Delivery Date"), issue and
deliver or cause to be delivered to Holder the number of Conversion Shares
determined pursuant to paragraph 3(a) above; provided, however, that any
Conversion Shares that are the subject of a Dispute Procedure shall be delivered
no later than the close of business on the third (3rd) Business Day following
the determination made pursuant thereto. The Company shall effect delivery of
Conversion Shares to Holder by, as long as the Transfer Agent participates in
FAST, crediting the account of Holder or its nominee at DTC (as specified in the
applicable Conversion Notice) with the number of Conversion Shares required to
be delivered, no later than the close of business on such Delivery Date. In the
event that the Transfer Agent is not a participant in FAST or if Holder so
specifies in its Conversion Notice or otherwise in writing on or before the
Conversion Date, the Company shall effect delivery of Conversion Shares by
delivering to Holder or its nominee physical certificates representing such
Conversion Shares, no later than the close of business on such Delivery Date. No
fractional Conversion Shares shall be issued; the Company shall, in lieu
thereof, either issue a number of Conversion Shares which reflects a rounding up
to the next whole number of shares or pay such amount in cash. Conversion Shares
shall be fully paid and non-assessable, free and clear of any liens, claims,
preemptive rights or encumbrances imposed by or through the Company. Conversion
Shares delivered to Holder shall not contain any restrictive legend as long as
the resale of such Conversion Shares (A) is covered by an effective Registration
Statement, (B) has been made pursuant to Rule 144 under the Securities Act, or
(C) may be made pursuant to Rule 144(k) under the Securities Act or any
successor rule or provision.

         (d)      Conversion Default. In the event that the Company fails for
any reason to deliver to Holder the number of Conversion Shares specified in the
applicable Conversion Notice (without any restrictive legend in the
circumstances described in clauses (A), (B) or (C) of paragraph 3(c)) on or
before the Delivery Date therefor (a "Conversion Default"), and such default
continues for seven (7) Business Days following delivery of a written notice of
such default by Holder to the Company, the Company shall pay to Holder payments
in the amount of (i) (N/365) multiplied by (ii) the aggregate amount of
principal and Interest which are the subject of such Conversion Default
multiplied by (iii) the Default Interest Rate, where "N" equals the number of
days elapsed between the original Delivery Date of such Conversion Shares and
the earlier to occur of (A) the date on which all of such Conversion Shares are
issued and delivered to Holder and (B) the date on which the portion of this
Debenture represented thereby are redeemed pursuant to the terms hereof.

                                       6
<PAGE>

Amounts payable under this paragraph (d) shall be paid to Holder in immediately
available funds on or before the fifth (5th) Business Day of the calendar month
following the calendar month in which such amounts have accrued and shall be in
addition to (and not in lieu of) any other remedies available to Holder,
including, without limitation, the rights of Holder under paragraph (e) below
and Section 6.

         (e)      In the event that the Holder has not received certificates
representing the Conversion Shares (without any restrictive legend in the
circumstances described in clauses (A), (B) or (C) of paragraph 3(c)) by the
seventh (7th) Business Day following a Conversion Default, the Holder may notify
the Company in writing of its election to revoke the Conversion Notice that is
the subject of such default, in which case, effective as of the date of such
revocation notice, such Conversion Notice shall be deemed rescinded and of no
further force or effect.

         (f)      Remedies. Nothing herein shall limit Holder's right to pursue
actual damages for the Company's failure to issue and deliver Conversion Shares
on the applicable Delivery Date (including, without limitation, damages relating
to any purchase of Common Stock by Holder to make delivery on a sale effected in
anticipation of receiving Conversion Shares upon Conversion, such damages to be
in an amount equal to (i) the aggregate amount paid by Holder for the Common
Stock so purchased minus (ii) the aggregate amount of net proceeds, if any,
received by Holder from the sale of the Conversion Shares issued by the Company
pursuant to such Conversion), and Holder shall have the right to pursue all
remedies available to it at law or in equity (including, without limitation, a
decree of specific performance and/or injunctive relief); provided, however,
that, in the event, following a Conversion Default, the Company delivers to
Holder the Conversion Shares that are required to be issued by the Company
pursuant to such conversion, Holder shall use commercially reasonable efforts to
sell such shares promptly following such delivery.

         (g)      No Impairment. The Company will not, by amendment of its
Articles of Incorporation or through any reorganization, transfer of assets,
consolidation, merger, dissolution, issue or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed hereunder by the Company but will at all
times in good faith assist in the carrying out of all the provisions of this
Section 3 and take all such action as may be necessary or appropriate in order
to protect the conversion rights of Holder against impairment.

         (h)      Exercise Limitations. In no event shall Holder be permitted to
convert this Debenture, if, upon such conversion, the number of shares of Common
Stock beneficially owned by Holder (other than shares which would otherwise be
deemed beneficially owned except for being subject to a limitation on conversion
or exercise analogous to the limitation contained in this paragraph (h)), would
exceed 4.99% of the number of shares of Common Stock then issued and
outstanding. As used herein, beneficial ownership shall be determined in
accordance with Section 13(d) of the Securities Exchange Act of 1934, as
amended, and the rules thereunder. To the extent that the limitation contained
in this paragraph (h) applies, the submission of a Conversion Notice by Holder
shall be deemed to be Holder's representation that this Debenture may be
convertible pursuant to the terms hereof and the Company shall be entitled to
rely on such representation without making any further inquiry as to whether
this paragraph (h) applies. Nothing contained herein shall be deemed to restrict
the right of Holder to convert any portion of this Debenture at such time as
such conversion will not violate the provisions of this paragraph (h). This
paragraph (h) may not be amended unless such amendment is approved by the
holders of a majority of the Common Stock then outstanding; provided, however,
that this paragraph (h) shall not apply, effective upon written notice from
Holder to the Company, at any time after the public announcement of a Major
Transaction or a Change of Control Transaction (each, as defined below).

4.       ADJUSTMENT TO CONVERSION PRICE.

                                       7
<PAGE>

         The Conversion Price shall be subject to adjustment from time to time
as provided in this Section 4. In the event that any adjustment of the
Conversion Price required herein results in a fraction of a cent or fraction of
a share, as applicable, the Conversion Price shall be rounded up or down to the
nearest cent or share, as applicable.

         (a)      Subdivision or Combination of Common Stock. If the Company, at
any time after the Closing Date, subdivides (by any stock split, stock dividend,
recapitalization, reorganization, reclassification or otherwise) the outstanding
shares of Common Stock into a greater number of shares, then after the date of
record for effecting such subdivision, the Conversion Price in effect
immediately prior to such subdivision will be proportionately reduced. If the
Company, at any time after the Closing Date, combines (by reverse stock split,
recapitalization, reorganization, reclassification or otherwise) the outstanding
shares of Common Stock into a smaller number of shares, then, after the date of
record for effecting such combination, the Conversion Price in effect
immediately prior to such combination will be proportionally increased.

         (b)      Distributions. If the Company shall declare or make any
distribution of its assets (or rights to acquire its assets) to holders of
Common Stock as a partial liquidating dividend or otherwise (including any
dividend or distribution to the Company's stockholders in cash or shares (or
rights to acquire shares) of capital stock of a subsidiary) (a "Distribution"),
the Company shall deliver written notice of such Distribution (a "Distribution
Notice") to Holder at least five (5) Business Days prior to the earlier to occur
of (x) the record date for determining stockholders entitled to such
Distribution (the "Record Date") and (y) the date on which such Distribution is
made (the "Distribution Date"). Holder shall be entitled to receive the same
amount and type of assets being distributed in such Distribution as though
Holder were a holder on the Record Date therefor of a number of shares of Common
Stock into which this Debenture is convertible as of such Record Date (such
number of shares to be determined at the Conversion Price then in effect and
without giving effect to any limitations on such conversion).

         (c)      Dilutive Issuances.

                  (i)      Adjustment Upon Dilutive Issuance. If, at any time
after the Closing Date, the Company issues or sells, or in accordance with
paragraph (c)(ii) below, is deemed to have issued or sold, any shares of Common
Stock for no consideration or for a consideration per share less than the
Conversion Price on the date of such issuance or sale (or deemed issuance or
sale) (a "Dilutive Issuance"), then effective immediately upon the Dilutive
Issuance, the Conversion Price shall be adjusted so as to equal an amount
determined by multiplying such Conversion Price by the following fraction:

                           N0 + N1
                           -------
                           N0 + N2

         where:

                           N0 =     the number of shares of Common Stock
                                    outstanding immediately prior to the
                                    issuance, sale or deemed issuance or sale of
                                    such additional shares of Common Stock in
                                    such Dilutive Issuance (without taking into
                                    account any shares of Common Stock issuable
                                    upon conversion, exchange or exercise of any
                                    securities or other instruments which are
                                    convertible into or exercisable or
                                    exchangeable for Common Stock ("Convertible
                                    Securities") or options, warrants or other
                                    rights to purchase or subscribe for Common
                                    Stock or Convertible Securities ("Purchase
                                    Rights"));

                           N1 =     the number of shares of Common Stock which
                                    the aggregate consideration,

                                       8
<PAGE>

                                    if any, received or receivable by the
                                    Company for the total number of such
                                    additional shares of Common Stock so issued,
                                    sold or deemed issued or sold in such
                                    Dilutive Issuance (which, in the case of a
                                    deemed issuance or sale, shall be calculated
                                    in accordance with subparagraph (c)(ii)
                                    below) would purchase at the Conversion
                                    Price in effect immediately prior to such
                                    Dilutive Issuance; and

                           N2 =     the number of such additional shares of
                                    Common Stock so issued, sold or deemed
                                    issued or sold in such Dilutive Issuance.

Notwithstanding the foregoing, no adjustment shall be made pursuant hereto if
such adjustment would result in an increase in the Conversion Price.

                  (ii)     Effect On Conversion Price Of Certain Events. For
purposes of determining the adjusted Conversion Price under subparagraph (c)(i)
above, the following will be applicable:

                           (1)      Issuance Of Purchase Rights. If the Company
         issues or sells any Purchase Rights, whether or not immediately
         exercisable, and the price per share for which Common Stock is issuable
         upon the exercise of such Purchase Rights (and the price of any
         conversion of Convertible Securities, if applicable) is less than the
         Conversion Price in effect on the date of issuance or sale of such
         Purchase Rights, then the maximum total number of shares of Common
         Stock issuable upon the exercise of all such Purchase Rights (assuming
         full conversion, exercise or exchange of Convertible Securities, if
         applicable) shall, as of the date of the issuance or sale of such
         Purchase Rights, be deemed to have been issued and sold by the Company
         for such price per share. For purposes of the preceding sentence, the
         "price per share for which Common Stock is issuable upon the exercise
         of such Purchase Rights" shall be determined by dividing (x) the total
         amount, if any, received or receivable by the Company as consideration
         for the issuance or sale of all such Purchase Rights, plus the minimum
         aggregate amount of additional consideration, if any, payable to the
         Company upon the exercise of all such Purchase Rights, plus, in the
         case of Convertible Securities issuable upon the exercise of such
         Purchase Rights, the minimum aggregate amount of additional
         consideration payable upon the conversion, exercise or exchange of all
         such Convertible Securities (determined in accordance with the
         calculation method set forth in subparagraph (c)(ii)(2) below), by (y)
         the maximum total number of shares of Common Stock issuable upon the
         exercise of all such Purchase Rights (assuming full conversion,
         exercise or exchange of Convertible Securities, if applicable). Except
         as provided in subparagraph (c)(ii)(3) below, no further adjustment to
         the Conversion Price shall be made upon the actual issuance of such
         Common Stock upon the exercise of such Purchase Rights or upon the
         conversion, exercise or exchange of Convertible Securities issuable
         upon exercise of such Purchase Rights.

                           (2)      Issuance Of Convertible Securities. If the
         Company issues or sells any Convertible Securities, whether or not
         immediately convertible, exercisable or exchangeable, and the price per
         share for which Common Stock is issuable upon such conversion, exercise
         or exchange is less than the Conversion Price in effect on the date of
         issuance or sale of such Convertible Securities, then the maximum total
         number of shares of Common Stock issuable upon the conversion, exercise
         or exchange of all such Convertible Securities shall, as of the date of
         the issuance or sale of such Convertible Securities, be deemed to have
         been issued and sold by the Company for such price per share. For the
         purposes of the immediately preceding sentence, the "price per share
         for which Common Stock is issuable upon such conversion, exercise or
         exchange" shall be determined by dividing (A) the total amount, if any,
         received or receivable by the Company as consideration for the issuance
         or sale of all such Convertible Securities, plus the minimum aggregate
         amount of additional

                                       9
<PAGE>

         consideration, if any, payable to the Company upon the conversion,
         exercise or exchange of all such Convertible Securities (determined in
         accordance with the calculation method set forth in this subparagraph
         (c)(ii)(2)), by (B) the maximum total number of shares of Common Stock
         issuable upon the exercise, conversion or exchange of all such
         Convertible Securities. Except as provided in subparagraph (c)(ii)(3)
         below, no further adjustment to the Conversion Price shall be made upon
         the actual issuance of such Common Stock upon conversion, exercise or
         exchange of such Convertible Securities.

                           (3)      Change In Option Price Or Conversion Rate.
         If there is a change at any time in (x) the purchase price or amount of
         additional consideration payable to the Company upon the exercise of
         any Purchase Rights; (y) the amount of additional consideration, if
         any, payable to the Company upon the conversion, exercise or exchange
         of any Convertible Securities the adjustment for which is not otherwise
         covered under subparagraph (c)(ii)(2) above; or (z) the rate at which
         any Convertible Securities are convertible into or exercisable or
         exchangeable for Common Stock, then in any such case, the Conversion
         Price in effect at the time of such change shall be readjusted to the
         Conversion Price which would have been in effect at such time had such
         Purchase Rights or Convertible Securities still outstanding provided
         for such changed purchase price, additional consideration or changed
         conversion, exercise or exchange rate, as the case may be, at the time
         initially issued or sold.

                           (4)      Calculation Of Consideration Received. If
         any Common Stock, Purchase Rights or Convertible Securities are issued
         or sold for cash, the consideration received therefor will be the
         amount received by the Company therefor, after deduction of all
         underwriting discounts or allowances in connection with such issuance,
         grant or sale. In case any Common Stock, Purchase Rights or Convertible
         Securities are issued or sold for a consideration part or all of which
         shall be other than cash, including in the case of a strategic or
         similar arrangement in which the other entity will provide services to
         the Company, purchase services from the Company or otherwise provide
         intangible consideration to the Company, the amount of the
         consideration other than cash received by the Company (including the
         net present value of the consideration expected by the Company for the
         provided or purchased services) shall be the fair market value of such
         consideration, except where such consideration consists of securities,
         in which case the amount of consideration received by the Company will
         be the average of the last sale prices thereof on the principal market
         for such securities during the period of ten Trading Days immediately
         preceding the date of receipt. In case any Common Stock, Purchase
         Rights or Convertible Securities are issued in connection with any
         merger or consolidation in which the Company is the surviving
         corporation, the amount of consideration therefor will be deemed to be
         the fair market value of such portion of the net assets and business of
         the non-surviving corporation as is attributable to such Common Stock,
         Purchase Rights or Convertible Securities, as the case may be. The
         independent members of the Company's Board of Directors shall calculate
         reasonably and in good faith, using standard commercial valuation
         methods appropriate for valuing such assets, the fair market value of
         any consideration other than cash or securities; provided, however,
         that if Holder does not agree to such fair market value calculation
         within three (3) Business Days after receipt thereof from the Company,
         then such fair market value shall be determined in good faith by an
         investment banker or other appropriate expert of national reputation
         selected by Holder and reasonably acceptable to the Company, with the
         costs of such appraisal to be borne by the Company.

                  (iii)    Exceptions To Adjustment Of Conversion Price.
Notwithstanding the foregoing, no adjustment to the Conversion Price shall be
made pursuant to this Section 4(c) upon the issuance of any Excluded Securities.
For purposes hereof, "Excluded Securities" means (1) securities purchased under
the Securities Purchase Agreement or the First Purchase Agreement; (2) Interest
Payment Shares and Put

                                       10
<PAGE>

Payment Shares, whether issued under the Debentures or the First Debentures, or
securities issued upon conversion or exercise of the Debentures, Warrants, First
Debentures or First Warrants; (3) shares of Common Stock issuable or issued to
employees, consultants or directors from time to time upon the exercise of
options, in such case granted or to be granted in the discretion of the Board of
Directors pursuant to one or more stock option plans or restricted stock plans
duly adopted by the Board of Directors of the Company; (4) shares of Common
Stock issued in connection with any stock split, stock dividend or
recapitalization of the Company; (5) shares of Common Stock or Purchase Rights
issued in connection with the acquisition by the Company of any corporation or
other entity as long as a fairness opinion with respect to such acquisition is
rendered by an investment bank of national recognition; (6) securities issued
upon conversion of outstanding shares of Series B 8% Convertible Preferred
Stock, provided that the terms of such preferred stock have not been amended
since the Closing Date; (7) 361,800 shares (200,000 shares to James C. Eckert
and 161,800 shares to G. Darcy Klug) and 100,000 options (40,000 options to
James C. Eckert and 60,000 options to G. Darcy Klug); and (8) 1,226,391 shares
issuable upon exercise of certain warrants and "investor options" described on
Schedule 3.5 to the Securities Purchase Agreement.

                  (iv)     Notice Of Adjustments. Upon the occurrence of each
adjustment or readjustment of the Conversion Price pursuant to this Section 4(c)
resulting in a change in the Conversion Price by more than one percent (1%), or
any change in the number or type of stock, securities and/or other property
issuable upon conversion of this Debenture, the Company, at its expense, shall
promptly compute such adjustment or readjustment or change and prepare and
furnish to Holder a certificate setting forth such adjustment or readjustment or
change and showing in detail the facts upon which such adjustment or
readjustment or change is based. The Company shall, upon the written request at
any time of Holder, furnish to Holder a like certificate setting forth (1) such
adjustment or readjustment or change, (2) the Conversion Price at the time in
effect and (3) the number of shares of Common Stock and the amount, if any, of
other securities or property which at the time would be received upon conversion
of this Debenture.

         (d)      Major Transactions. In the event of a merger, consolidation,
business combination, tender offer, exchange of shares, recapitalization,
reorganization, redemption or other similar event, as a result of which shares
of Common Stock shall be changed into the same or a different number of shares
of the same or another class or classes of stock or securities or other assets
of the Company or another entity or the Company shall sell all or substantially
all of its assets (each of the foregoing being a "Major Transaction"), the
Company will give Holder at least twenty (20) days written notice prior to the
closing of such Major Transaction in a manner that does not constitute
disclosure of material non-public information (unless otherwise previously
consented to in writing by Holder), and: (i) Holder shall be permitted to
convert this Debenture in whole or in part at any time prior to the record date
for the receipt of such consideration and shall be entitled to receive, for each
share of Common Stock issuable to Holder for such conversion, the same per share
consideration payable to the other holders of Common Stock in connection with
such Major Transaction, and (ii) if and to the extent that Holder retains any
portion of this Debenture following such record date, the Company will cause the
surviving or, in the event of a sale of assets, purchasing entity, as a
condition precedent to such Major Transaction, to assume the obligations of the
Company with respect to this Debenture, with such adjustments to the Conversion
Price and the securities covered hereby as may be necessary in order to preserve
the economic benefits of this Debenture to Holder.

         (e)      Adjustments; Additional Shares, Securities or Assets. In the
event that at any time, as a result of an adjustment made pursuant to this
Section 4, Holder shall, upon conversion of this Debenture, become entitled to
receive securities or assets (other than Common Stock) then, wherever
appropriate, all references herein to shares of Common Stock shall be deemed to
refer to and include such shares and/or other securities or assets; and
thereafter the number of such shares and/or other securities or assets shall be
subject to adjustment from time to time in a manner and upon terms as nearly
equivalent as practicable to the provisions of this Section 4.

5.       HOLDER PUT OPTION.

         (a)      Put Option; Put Notice. Holder shall have the right, following
the Effective Date, to require the Company to repurchase this Debenture on the
terms and conditions set forth in this Section 5 (the "Put Option"). The Put
Option shall be exercisable for all or any of the ten (10) consecutive full
calendar months (each, a "Put Month"), commencing with (i) the first full
calendar month after the Effective Date, if the Effective Date occurs on or
prior to the fifteenth (15th) calendar day of a calendar month, or (ii) the
second full calendar month after the Effective Date, if the Effective Date
occurs later than the fifteenth (15th) calendar day of a calendar month;
provided, however, that notwithstanding the foregoing, if and to the extent that
the Company is unable to fully satisfy (in cash, shares of Common Stock (such
shares, the "Put Payment Shares") or a combination thereof) the amount being put
(the "Put Amount") by Holder for any Put Month for any reason, such Put Month
and all remaining Put Months shall (at Holder's sole option) be tolled and not
counted against the ten (10) Put Months that Holder is entitled to hereunder
until the date on which the Company has satisfied either of the following
conditions (each, a "Put Cure Condition"): (i) Shareholder Approval has been
obtained or (ii) in Holder's reasonable determination, the Company has
sufficient cash (or a combination of cash and Put Payment Shares) that it can
deliver to Holder to satisfy Holder's rights under this Section 5. After the
date on which a Put Cure Condition is satisfied (the "Put Cure Date"), and
assuming such condition remains satisfied, the Put Months shall resume with (i)
the first full calendar month after the Put Cure Date, if the Put Cure Date
occurs on or prior to the fifteenth (15th) calendar day of a calendar month, or
(ii) the second full calendar month after the Put Cure Date, if the Put Cure
Date occurs later than the fifteenth (15th) calendar day of a calendar month.

         (b)      Put Notice; Monthly Put Amount. In order to exercise the Put
Option for a Put Month, Holder must deliver written notice thereof specifying
the Put Amount to the Company at least five (5) Business Days prior to the first
day of such Put Month (a "Put Notice"). Notwithstanding the foregoing or any
provision herein to the contrary, the Put Amount for any Put Month shall not
exceed the product of 0.0875 and the original principal amount of this Debenture
(such sum being referred to herein as Holder's "Monthly Put Amount"). In the
event that Holder transfers all or a part of this Debenture, Holder shall also
be deemed to have transferred a pro rata portion of Holder's Monthly Put Amount.

         (c)      Company Option to Deliver Cash or Stock. To the extent that
the Company elects to pay some or all of the Put Amount in cash, the Company
shall make such payment on or before the fifth (5th) Business Day occurring
during the applicable Put Month. To the extent that the Company elects to pay
some or all of the Put Amount by issuing Put Payment Shares, the Company shall
(subject to Section 5(d) below) deliver, with respect to each Pricing Period (as
defined below) that occurs during the applicable Put Month, a number of Put
Payment Shares equal to the Pricing Period Amount (as defined below) divided by
the Pricing Period Share Price (as defined below) for such Pricing Period. As
used herein, "Pricing Period Amount" means an amount equal to (i) the portion of
the Put Amount that the Company is electing to pay in Put Payment Shares
multiplied by (ii) a fraction, the numerator of which shall be the number of
Business Days in such Pricing Period and the denominator of which shall be the
number of Business Days in such Put Month. Each Put Month shall consist of four
Pricing Periods. The first Pricing Period in a Put Month shall begin on the
first Trading Day and end on (and include) the fifth Trading Day of such month,
the second Pricing Period shall begin on the sixth Trading Day and end on (and
include) the tenth Trading Day of such month, the third Pricing Period shall
begin on the eleventh Trading Day and end on (and include) the fifteenth Trading
Day of such month, and the fourth Pricing Period shall consist of the remaining
Trading Days in such Put Month (each, a "Pricing Period"). "Pricing Period Share
Price" means, with respect to a particular Pricing Period, an amount equal to
(x) the Pricing Period Closing Price for such Pricing Period multiplied by (y)
eighty seven and one-half percent (87.5%). With respect to each Pricing Period,
the Company shall deliver the Put Payment Shares for such Pricing Period on the
third Business Day immediately following the

                                       12
<PAGE>

last Business Day of such Pricing Period (each such date, a "Settlement Date").

         (d)      Conditions to the issuance of the Put Payment Shares.
Notwithstanding the foregoing, the Company shall not be permitted to deliver Put
Payment Shares upon delivery of a Put Notice by Holder if any of the following
conditions have not been satisfied (or waived by Holder in its sole discretion)
on the Settlement Date for such Pricing Period:

                  (i)      the number of shares of Common Stock authorized,
unissued and unreserved for all other purposes, or held in the Company's
treasury, is sufficient to pay the sum of (1) the number of Conversion Shares
issuable upon the conversion in full of the Debentures (without regard to any
limitation on such conversion) plus (2) the number of Warrant Shares issuable
upon the exercise in full of the Warrants (without regard to any limitation on
such exercise) plus (3) the number of Put Payment Shares issuable with respect
to such Pricing Period;

                  (ii)     the Common Stock is authorized for quotation on the
Nasdaq SmallCap Market or Nasdaq National Market or listed on the New York Stock
Exchange;

                  (iii)    the Registration Statement is effective and available
for the resale of the Put Payment Shares by Holder or such shares are eligible
for resale to the public pursuant to Rule 144(k) under the Securities Act; and

                  (iv)     an Event of Default has not occurred and is not
continuing, and no event has occurred that with the giving of notice or passage
of time, or both, would constitute an Event of Default; and

                  (v)      the issuance of such Put Payment Shares would not
violate Section 3(h) of this Debenture or Section 4.10 of the Securities
Purchase Agreement.

If any of the foregoing conditions are not satisfied (or waived by Holder in its
sole discretion) as of such Settlement Date, the Company shall, in lieu of
delivering the Put Payment Shares for the applicable Pricing Period, pay Holder
the Pricing Period Amount for such Pricing Period in cash on the Settlement Date
for such Pricing Period.

         (e)      Delivery of Put Payment Shares. If Holder is entitled to
receive any Put Payment Shares, Holder shall be treated for all purposes as the
record holder of such Put Payment Shares as of the applicable Settlement Date.
The Company shall effect delivery of Put Payment Shares to Holder by, as long as
the Transfer Agent is participating in FAST, crediting the account of Holder or
its nominee at DTC with the number of Put Payment Shares required to be
delivered, no later than the close of business on the applicable Settlement
Date. In the event that the Transfer Agent is not a participant in FAST as of
the applicable Settlement Date, or if Holder notifies the Company in writing
prior to the applicable Settlement Date that Holder wishes to receive physical
certificates, the Company shall effect delivery of Put Payment Shares by
delivering to Holder or its nominee physical certificates representing such Put
Payment Shares, no later than the close of business on such Settlement Date. No
fractional Put Payment Shares shall be issued; the Company shall, in lieu
thereof, either issue a number of Put Payment Shares which reflects a rounding
up to the next whole number of shares or pay such amount in cash. Put Payment
Shares shall be fully paid and non-assessable, free and clear of any liens,
claims, preemptive rights or encumbrances imposed by or through the Company. Put
Payment Shares delivered to Holder shall not contain any restrictive legend as
long as the resale of such Put Payment Shares (A) is covered by an effective
Registration Statement, (B) has been made pursuant to Rule 144 under the
Securities Act, or (C) may be made pursuant to Rule 144(k) under the Securities
Act or any successor rule or provision.

         (f)      Put Payment Default. In the event that the Company fails for
any reason to deliver to Holder

                                       13
<PAGE>

certificates representing the appropriate number of Put Payment Shares (without
any restrictive legend in the circumstances described in clauses (A), (B) or (C)
of paragraph 3(c)) on or before the Settlement Date therefor (a "Put Payment
Default"), and such failure continues for three (3) Business Days following
delivery of a written notice of such failure by Holder to the Company, the
Company shall pay to Holder payments in the amount of (i) (N/365) multiplied by
(ii) the applicable Pricing Period Liquidation Value multiplied by (iii) the
Default Interest Rate, where "N" equals the number of days elapsed between the
original Settlement Date for such Put Payment Shares and the date on which all
of the certificates representing such Put Payment Shares are issued and
delivered to Holder. Amounts payable under this Section 5(f) shall be paid to
Holder in immediately available funds on or before the fifth (5th) Business Day
of the calendar month immediately following the calendar month in which such
amounts have accrued and shall be in addition to (and not in lieu of) any other
remedies available to Holder, including, without limitation, the rights of
Holder under paragraph (g) below and Section 6.

         (g)      Remedies. Nothing herein shall limit Holder's right to pursue
actual damages for the Company's failure to issue and deliver Put Payment Shares
on the applicable settlement Date (including, without limitation, damages
relating to any purchase of Common Stock by Holder to make delivery on a sale
effected in anticipation of receiving Put Payment Shares with respect to a
Pricing Period, such damages to be in an amount equal to (i) the aggregate
amount paid by Holder for the Common Stock so purchased minus (ii) the aggregate
amount of net proceeds, if any, received by Holder from the sale of the Put
Payment Shares issued by the Company with respect to a Pricing Period), and
Holder shall have the right to pursue all remedies available to it at law or in
equity (including, without limitation, a decree of specific performance and/or
injunctive relief); provided, however, that, in the event, following a Put
Payment Default, the Company delivers to Holder the Put Payment Shares that are
required to be issued by the Company with respect to the applicable Pricing
Period, Holder shall use commercially reasonable efforts to mitigate the damages
that Holder incurs as a result of such Put Payment Default.

6.       MANDATORY REDEMPTION BY HOLDER.

         (a)      Mandatory Redemption. In the event that an Event of Default
(as defined below) occurs, Holder shall have the right, upon written notice to
the Company (a "Mandatory Redemption Notice"), to require the Company to redeem
all or any portion of this Debenture (a "Mandatory Redemption") at the
applicable Mandatory Redemption Price (as defined below) in cash. The Mandatory
Redemption Notice shall specify the effective date of such Mandatory Redemption
(the "Mandatory Redemption Date"), which date must be at least three (3)
Business Days following the Business Day on which the Mandatory Redemption
Notice is delivered to the Company, and the amount of this Debenture to be
redeemed. In order to effect a Mandatory Redemption hereunder, Holder must
deliver a Mandatory Redemption Notice no later than the close of business on the
Business Day immediately following the Business Day on which an Event of Default
has been cured or ceases to continue; provided, however, that with respect to a
Change of Control Transaction (as defined below), Holder must deliver a
Mandatory Redemption Notice no later than the close of business on the Business
Day following the date on which such Change of Control Transaction is
consummated.

         (b)      Mandatory Redemption Price. The "Mandatory Redemption Price"
means, with respect to a Mandatory Redemption Date, an amount equal to the
greater of (i) the outstanding principal of and accrued and unpaid Interest on
this Debenture and (ii) the product of (1) the aggregate number of Conversion
Shares into which this Debenture is then convertible (without regard to any
limitation on such conversion) multiplied by (2) the Mandatory Redemption
Closing Price for such Mandatory Redemption Date.

         (c)      Payment of Mandatory Redemption Price. If Holder exercises its
right to redemption, the Company shall pay the Mandatory Redemption Price to
Holder no later than the fifth (5th) Business Day

                                       14
<PAGE>

following the Mandatory Redemption Date. If the Company fails to pay the
Mandatory Redemption Price to Holder within five (5) Business Days of the
Mandatory Redemption Date, Holder shall be entitled to interest thereon at the
Default Interest Rate from the Mandatory Redemption Date until the Mandatory
Redemption Price has been paid in full.

         (d)      Event of Default. Each of the following events shall be deemed
an "Event of Default":

                  (i)      The Company defaults in the payment of any payment of
Interest or any principal payable under this Debenture (or under any other debt
of the Company) as and when due, or an Event of Default (as defined in the First
Debentures) occurs;

                  (ii)     a Liquidation Event occurs or is publicly announced;

                  (iii)    the Company fails for any reason (including without
limitation as a result of not having a sufficient number of shares of Common
Stock authorized and reserved for issuance or otherwise, and except as a result
of the limitation described in paragraph 3(h) hereof) to issue and deliver to
Holder the total number of shares of Common Stock issuable to Holder upon a
conversion of this Debenture or upon the exercise of the Put Option, and such
failure to issue Common Stock continues for ten (10) Business Days after written
notice thereof to the Company from Holder;

                  (iv)     the Company breaches, in a material respect, any
material term or condition of (1) this Debenture or of the Securities Purchase
Agreement, the Registration Rights Agreement or the Warrants (including, without
limitation, any representation or warranty made by the Company herein or
therein), and such breach continues for a period of ten (10) Business Days after
written notice thereof to the Company from Holder, or (2) any other agreement of
the Company relating to any of its debt obligations (including, without
limitation, any representation or warranty made by the Company therein), and
such breach remains uncured after the expiration of any applicable cure period;

                  (v)      the effectiveness of the Registration Statement

7.       PRIORITY ON LIQUIDATION.

         In the event of (x) the insolvency of the Company (determined in
accordance with GAAP) or any insolvency or bankruptcy proceedings, or any
receivership, liquidation, reorganization or other similar proceedings in
connection therewith, relative to the Company or to its creditors, as such, or
to its assets or (y) the dissolution or other winding up of the Company, whether
voluntary or involuntary and whether or not involving insolvency or bankruptcy
proceedings, or (z) any assignment for the benefit of creditors or any
marshalling of the material assets or material liabilities of the Company (each
a "Liquidation Event"), then, and in any such event, Holder shall first be
entitled to receive payment in full of all principal of, and all Interest and
other amounts due or to become due on, this Debenture before any dividends or
any other amounts are paid with respect to any Junior Securities, whether on
account of any purchase, exchange or redemption or other acquisition of such
Junior Securities, at maturity or otherwise.

8.       MISCELLANEOUS.

         (a)      Failure to Exercise Rights not Waiver. No failure or delay on
the part of Holder in the exercise of any power, right or privilege hereunder
shall operate as a waiver thereof, nor shall any single or partial exercise of
any such power, right or privilege preclude any other or further exercise
thereof. All rights and remedies of Holder hereunder are cumulative and not
exclusive of any rights or remedies otherwise available.

         (b)      Remedies, Characterization, Other Obligations, Breaches and
Injunctive Relief. The remedies provided to Holder in this Debenture shall be
cumulative and in addition to all other remedies available to Holder hereunder
or under any Transaction Document, at law or in equity (including without
limitation a decree of specific performance and/or other injunctive relief), no
remedy contained herein shall be deemed a waiver of compliance with the
provisions giving rise to such remedy and nothing contained herein shall limit
Holder's right to pursue actual damages for any failure by the Company to comply
with the terms of this Debenture. The Company agrees that there shall be no
characterization concerning this instrument other than as specifically provided
herein. Amounts set forth or provided for herein with respect to payments,
conversion and the like (and the computation thereof) shall be the amounts to be
received by Holder and shall not, except as expressly provided herein, be
subject to any other obligation of the Company (or the performance thereof). The
Company acknowledges that a breach by it of its obligations hereunder will cause
irreparable harm to Holder and that the remedy at law for any such breach may be
inadequate.

         (c)      Notices. Any notice, demand or request required or permitted
to be given by the Company or Holder pursuant to the terms hereof shall be in
writing and shall be deemed given (i) when delivered personally or by verifiable
facsimile transmission (with a hard copy to follow), (ii) on the next Business
Day after timely delivery to an overnight courier and (iii) on the Business Day
actually received if deposited in the U.S. mail (certified or registered mail,
return receipt requested, postage prepaid), addressed as follows:

and if to Holder, at such address as Holder shall have furnished the Company in
writing.

         (d)      Transfer of Debenture. Holder may sell, transfer, assign,
pledge or otherwise dispose of this Debenture, in whole or in part, as long as
such sale or other disposition is made pursuant to an effective registration
statement or an exemption from the registration requirements of the Securities
Act. Upon such transfer or other disposition (other than a pledge or
hypothecation of this Debenture), Holder shall deliver this Debenture to the
Company together with a written notice to the Company, substantially in the form
of the Transfer Notice attached hereto as Annex III (the "Transfer Notice"),
indicating the person or persons to whom this Debenture shall be transferred
and, if less than all of this Debenture is transferred, the principal amount of
this Debenture to be transferred to each such person. Within three (3) Business
Days of receiving a Transfer Notice and the original of this Debenture, the
Company shall deliver to the each transferee designated by Holder a Debenture or
Debentures of like tenor and terms for the appropriate amount of principal and,
if less than all this Debenture is transferred, shall deliver to Holder a
Debenture for the remaining amount of principal.

         (e)      Lost or Stolen Debenture. Upon receipt by the Company of
evidence of the loss, theft, destruction or mutilation of this Debenture, and
(in the case of loss, theft or destruction) of indemnity or security reasonably
satisfactory to the Company, and upon surrender and cancellation of this
Debenture if mutilated, the Company shall execute and deliver to Holder a new
Debenture identical in all respects to the original Debenture.

         (f)      Amendment and Waiver. No amendment, modification or other
change to, or waiver of any provision of, this Debenture may be made unless (i)
such amendment, modification, change or waiver is set forth in writing and is
signed by the Company and Holder and (ii) the Company obtains the consent in
writing of the holders of at least sixty-six percent (66%) of the unpaid
principal amount of the Debentures then outstanding.

         (g)      Severability of Provisions. Whenever possible, each provision
hereof shall be interpreted in a manner as to be effective and valid under
applicable law, but if any provision hereof is held to be prohibited by or
invalid under applicable law, such provision shall be ineffective only to the
extent of such prohibition or invalidity, without invalidating or otherwise
adversely affecting the remaining provisions hereof. If a court of competent
jurisdiction should determine that a provision hereof would be valid or
enforceable if a period of time were extended or shortened or a particular
percentage were increased or decreased, then such court may make such change as
shall be necessary to render the provision in question effective and valid under
applicable law.

         (h)      Governing Law. This Debenture shall be governed by and
construed in accordance with the laws of the State of New York applicable to
contracts made and to be performed entirely within the State of New York.

         (i)      Successors and Assigns. The terms and conditions of this
Debenture shall inure to the benefit of and be binding upon the respective
successors (whether by merger or otherwise) and permitted assigns of the

                                       17
<PAGE>

Company and Holder. Holder may not assign its rights and obligations hereunder
without the prior written consent of the Company, which consent shall not be
unreasonably withheld; provided, however, that no such consent shall be required
for an assignment to an Affiliate of an Investor. If the Company consents to
such transfer (or such transfer is to an Affiliate of an Investor), the
transferee shall execute an acknowledgment agreeing to be bound by the
applicable provisions of this Debenture, in which case the term "Holder" shall
be deemed to refer to such transferee as though such transferee were an original
signatory hereto. The Company may not assign it rights or obligations under this
Debenture without the prior written consent of the holders of at least
two-thirds (2/3) of the aggregate principal amount of the Debentures then
outstanding.

         (j)      Entire Agreement. This Debenture, the Securities Purchase
Agreement, the Registration Rights Agreement, and the other Transaction
Documents constitute the entire agreement among the parties hereto with respect
to the subject matter hereof and thereof. There are no restrictions, promises,
warranties or undertakings, other than those set forth or referred to herein and
therein. This Debenture, the Securities Purchase Agreement, the Registration
Rights Agreement, and the other Transaction Documents supersede all prior
agreements and understandings among the parties hereto with respect to the
subject matter hereof and thereof.

         (k)      Headings. The headings in this Agreement are for convenience
of reference only and shall not limit or otherwise affect the meaning hereof.
