      Interest. The Obligor promises to pay to the order of the Holder cash
interest on the principal amount hereof at a rate per annum equal to eight
percent (8%). The Obligor shall make a cash payment of $10,000 towards the
accrued and outstanding interest on this Note on April 29, 2006. The balance of
$121,846.00 of interest on the principal amount hereof accruing as of April 29,
2006 shall be automatically converted into shares (the "Conversion Shares") of
the Obligor's Class A Common Stock, par value $0.001 per share ("Common Stock"),
at a conversion price equal to the bid price of the Borrower's Common Stock, as
quoted by Bloomberg, LP (the "Bid Price") as of April 29, 2006 once the
Borrower's Common Stock is listed on the Principal Market. On April 29, 2007,
and continuing annually on April 29th of each year thereafter (each, an
"Interest Payment Date"), the Obligor shall made a cash payment of fifty percent
(50%) of the then accrued and outstanding interest on the principal balance of
this Note (or $43,988.72), with the balance automatically converted into
Conversion Shares of the Obligor's Common Stock at the Bid Price as of Interest
Payment Date. Interest shall be calculated on the basis of a year of 365 days
and for the number of days actually elapsed. All payments shall be applied first
to accrued interest and thereafter to principal. The cash payments of principal
and interest hereunder shall be made by wire transfer pursuant to wire transfer
instructions provided by Holder on or before the Maturity Date in currency of
the United States of America which at the time of payment shall be legal tender
therein for the payment of public and private debts. In the case of a default in
payment of the amount due on the Maturity Date, the amount due shall bear
interest at a rate of eleven percent (11%) per annum, which shall accrue from
the date of such default to the date the payment of such amount has been made or
duly provided for. Interest on any overdue principal amount shall be payable on
demand. Nothing in this Note shall require the Obligor to pay interest at a rate
exceeding the maximum amount permitted by applicable law to be charged by Holder
(the "Maximum Rate"). If the amount of interest payable for the account of
Holder would exceed the Maximum Rate, the amount of interest payable for its
account shall automatically be reduced to the Maximum Rate.

      Prepayment. The Obligor shall not have the right to prepay the principal
hereof in whole or in part.

      No Waiver. No failure or delay by the Holder in exercising any right,
power or privilege under this Note shall operate as a waiver thereof nor shall
any single or partial exercise thereof preclude any other or further exercise
thereof or the exercise of any other right, power or privilege. The rights and
remedies herein provided shall be cumulative and not exclusive of any rights or
remedies provided by law. No course of dealing between the Obligor and the
Holder shall operate as a waiver of any rights by the Holder.

      Waiver of Presentment and Notice of Dishonor. The Obligor and all
endorsers, guarantors and other parties that may be liable under this Note
hereby waive presentment, dishonor, demand, protest and notice of presentment,
notice of protest and notice of dishonor of any of the obligations created under
this Note and each and every notice of any kind in connection with the delivery,

<PAGE>

acceptance, performance and enforcement of this Note, and, to the fullest extent
permitted by law, all rights to assert any statute of limitations to an action
hereunder.

      Place of Payment. All payments of principal of this Note and the interest
due thereon shall be made by wire transfer in accordance with the Holder's wire
transfer instructions to be delivered by Holder to Obligor in advance of the
time of payment or at such other place as the Holder may from time to time
designate in writing to the Obligor. Notification that such wire was transmitted
shall be emailed to Sanji Arisawa at sarisawa@arisawa.co.jp and to Mike Peterson
at MPeter484@aol.com.

      Events of Default. The entire unpaid principal amount of this Note and the
interest due thereon shall, at the option of the Holder exercised by written
notice to the Obligor, forthwith become and be due and payable, without
presentment, demand, protest or other notice of any kind, all of which are
hereby expressly waived, if any one or more of the following events (herein
called "Events of Default") shall have occurred (for any reason whatsoever and
whether such happening shall be voluntary or involuntary or come about or be
effected by operation of law or pursuant to or in compliance with any judgment,
decree or order of any court or any order, rule or regulation of any
administrative or governmental body) and be continuing at the time of such
notice, that is to say:

            (a) failure to pay any principal or interest on this Note on or
before the Maturity Date;

            (b) breach of the Security Agreement;

      Remedies. In case any one or more of the Events of Default specified above
shall have occurred and be continuing, the Holder may proceed to protect and
enforce its rights either by suit in equity and/or by action at law, whether for
the specific performance of any covenant or agreement contained in this Note or
in aid of the exercise of any power granted in this Note, or the Holder may
proceed to enforce the payment of all sums due upon this Note or to enforce any
other legal or equitable right of the Holder. Obligor further promises to pay
reasonable attorneys' fees, court costs and any other expenses, losses, charges,
damages incurred or advances made by Holder in the protection or enforcement of
its rights caused by Obligor's default under the terms of this Note, in
connection with an refinancing or restructuring of this Note, in connection with
any litigation involving the transactions contemplated by this Note and in
protecting, preserving, collecting, leasing, selling or taking possession of the
Collateral and attempting to do any of the foregoing.

      In an Event of Default, Holder may exercise in respect of the Collateral,
in addition to all other rights and remedies provided for herein or otherwise
available to it, all the rights and remedies of a secured party on default under
the uniform commercial code in effect under the law of the State of New York
(the "UCC") (whether or not the UCC applies to the affected Collateral) and also
may: (a) require Obligor to, and Obligor hereby agrees that it will, at its

<PAGE>

expense and upon request of Holder forthwith, have any and all appropriate
instruments prepared to irrevocably assign to Holder or its designee the general
intangible rights which are a component of the Collateral and execute and
deliver the same to accomplish Holder's rights hereunder and file such
instruments with the appropriate governmental authorities; and (b) without
notice except as specified below, sell the Collateral or any part thereof in one
or more parcels at public or private sale, at any of Holder's offices or
elsewhere, at such time or times, for cash, on credit or for future delivery,
and at such price or prices and upon such other terms as Holder may deem
commercially reasonable. Company agrees that, to the extent notice of sale shall
be required by law, at least ten days' notice to Company of the time and place
of any public sale or the time after which any private sale is to be made shall
constitute reasonable notification. At any sale of the Collateral, if permitted
by law, Holder may bid (which bid may be, in whole or in part, in the form of
cancellation of indebtedness) for the purchase of the Collateral of any portion
thereof for the account of Holder (on behalf of Holder). Holder shall not be
obligated to make any sale of Collateral regardless of notice of sale having
been given. Holder may adjourn any public or private sale from time to time by
announcement at the time and place fixed therefor, and such sale may, without
further notice, be made at the time and place to which it was so adjourned. To
the extent permitted by law, Company hereby specifically waives all rights of
redemption, stay or appraisal which it has or may have under any law now
existing or hereafter enacted.

      Beyond the safe custody thereof, Holder shall have no duty with respect to
any Collateral in its possession or control (or in the possession or control of
any agent or bailee) or with respect to any income thereon or the preservation
of rights against prior parties or any other rights pertaining thereto. Holder
shall be deemed to have exercised reasonable care in the custody and
preservation of the Collateral in its possession if the Collateral is accorded
treatment substantially equal to that which it accords its own property. Holder
shall not be liable or responsible for any loss or damage to any of the
Collateral, or for any diminution in the value thereof, by reason of the act or
omission of any warehouseman, carrier, forwarding agency, consignee or other
agent or bailee selected by Holder in good faith.

      Upon the occurrence and during the continuance of an Event of Default, the
proceeds of any sale of, or other realization upon, all or any part of the
Collateral shall be applied: first, to all fees, costs and expenses incurred by
Holder with respect to the Loan Agreement; second, to all fees due and owing to
Holder; third, to accrued and unpaid interest under the Loan Agreement and this
Note; fourth, to the principal amounts due under the Loan Agreement and this
Note; fifth, to any other indebtedness or obligations of Obligor owing to
Holder.

      All rights and remedies of Lender under this Note are in addition to all
rights and remedies given to Lender contained in any other agreement, instrument
or document or available to Lender at law or in equity. All such rights and
remedies are cumulative and not exclusive or exhaustive and may be exercised
successively or concurrently. No exercise of any right or remedy shall be deemed
an election of remedies and preclude exercise of any other right or remedy.

<PAGE>

      Severability. In the event that one or more of the provisions of this Note
shall for any reason be held invalid, illegal or unenforceable in any respect,
such invalidity, illegality or unenforceability shall not affect any other
provision of this Note, but this Note shall be construed as if such invalid,
illegal or unenforceable provision had never been contained herein.

      Governing Law. This Note and the rights and obligations of the Obligor and
the Holder shall be governed by and construed in accordance with the laws of the
State of New York without regard to New York State principles of conflict of
laws.

      No Set-Off. Obligor will not be entitled to offset against any of its
financial obligations to Lender under this Note, any obligation owed to it or
any of its affiliates by or for Lender or any affiliate of Lender.

      Assignment. The Obligor shall not assign its obligations under this Note.

      Amended and Restated Note. THIS AMENDED AND RESTATED SECURED PROMISSORY
NOTE (THE "AMENDED AND RESTATED NOTE") AMENDS AND RESTATES THAT CERTAIN SECURED

      Section 3. Conversion.

      (a) (i) Conversion at Option of Holder.

            (A) This Debenture shall be convertible into shares of Common Stock
at the option of the Holder, in whole or in part at any time and from time to
time, after the Original Issue Date (as defined in Section 4) (subject to the
limitations on conversion set forth in Section 3(a)(ii) hereof). The number of
shares of Common Stock issuable upon a conversion hereunder equals the quotient
obtained by dividing (x) the outstanding amount of this Debenture to be
converted by (y) the Conversion Price (as defined in Section 3(c)(i)). The
Obligor shall deliver Common Stock certificates to the Holder prior to the Fifth
(5th) Trading Day after a Conversion Date.

            (B) Notwithstanding anything to the contrary contained herein, if on
any Conversion Date: (1) the number of shares of Common Stock at the time
authorized, unissued and unreserved for all purposes, or held as treasury stock,
is insufficient to pay principal and interest hereunder in shares of Common
Stock; (2) the Common Stock, once registered pursuant to the Amended and
Restated Investor Registration Rights Agreement, is not listed or quoted for
trading on the OTC or on a Subsequent Market; (3) the Obligor has failed to
timely satisfy its conversion; or (4) the issuance of such shares of Common
Stock would result in a violation of Section 3(a)(ii), then, at the option of
the Holder, the Obligor, in lieu of delivering shares of Common Stock pursuant
to Section 3(a)(i)(A), shall deliver, within three (3) Trading Days of each
applicable Conversion Date, an amount in cash equal to the product of the
outstanding principal amount to be converted plus any interest due therein
divided by the Conversion Price and multiplied by the highest closing price of
the stock from date of the conversion notice till the date that such cash
payment is made.

      Further, if the Obligor shall not have delivered any cash due in respect
of conversion of this Debenture or as payment of interest thereon by the fifth
(5th) Trading Day after the Conversion Date, the Holder may, by notice to the
Obligor, require the Obligor to issue shares of Common Stock pursuant to Section
3(c), except that for such purpose the Conversion Price applicable thereto shall
be the lesser of the Conversion Price on the Conversion Date and the Conversion
Price on the date of such Holder demand. Any such shares will be subject to the
provisions of this Section.

            (C) The Holder shall effect conversions by delivering to the Obligor
a completed notice in the form attached hereto as Exhibit A (a "Conversion
Notice"). The date on which a Conversion Notice is delivered is the "Conversion
Date." Unless the Holder is converting the entire principal amount outstanding
under this Debenture, the Holder is not required to physically surrender this
Debenture to the Obligor in order to effect conversions. Conversions hereunder
shall have the effect of lowering the outstanding principal amount of this
Debenture plus all accrued and unpaid interest thereon in an amount equal to the
applicable conversion. The Holder and the Obligor shall maintain records showing
the principal amount converted and the date of such conversions. In the event of
any dispute or discrepancy, the records of the Holder shall be controlling and
determinative in the absence of manifest error.

            (ii) Certain Conversion Restrictions.

                  (A) A Holder may not convert this Debenture or receive shares
of Common Stock as payment of interest hereunder to the extent such conversion
or receipt of such interest payment would result in the Holder, together with
any affiliate thereof, beneficially owning (as determined in accordance with
Section 13(d) of the Exchange Act and the rules promulgated thereunder) in
excess of 4.9% of the then issued and outstanding shares of Common Stock,
including shares issuable upon conversion of, and payment of interest on, this
Debenture held by such Holder after application of this Section. Since the
Holder will not be obligated to report to the Obligor the number of shares of
Common Stock it may hold at the time of a conversion hereunder, unless the
conversion at issue would result in the issuance of shares of Common Stock in
excess of 4.9% of the then outstanding shares of Common Stock without regard to
any other shares which may be beneficially owned by the Holder or an affiliate
thereof, the Holder shall have the authority and obligation to determine whether
the restriction contained in this Section will limit any particular conversion
hereunder and to the extent that the Holder determines that the limitation
contained in this Section applies, the determination of which portion of the
principal amount of this Debenture is convertible shall be the responsibility
and obligation of the Holder. If the Holder has delivered a Conversion Notice
for a principal amount of this Debenture that, without regard to any other
shares that the Holder or its affiliates may beneficially own, would result in
the issuance in excess of the permitted amount hereunder, the Obligor shall
notify the Holder of this fact and shall honor the conversion for the maximum
principal amount permitted to be converted on such Conversion Date in accordance
with the periods described in Section 3(a)(i)(A) and, at the option of the
Holder, either retain any principal amount tendered for conversion in excess of
the permitted amount hereunder for future conversions or return such excess
principal amount to the Holder. The provisions of this Section may be waived by
a Holder (but only as to itself and not to any other Holder) upon not less than
65 days prior notice to the Obligor. Other Holders shall be unaffected by any
such waiver.

      (b) (i) Nothing herein shall limit a Holder's right to pursue actual
damages or declare an Event of Default pursuant to Section 2 herein for the
Obligor 's failure to deliver certificates representing shares of Common Stock
upon conversion within the period specified herein and such 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,
in each case without the need to post a bond or provide other security. The
exercise of any such rights shall not prohibit the Holder from seeking to
enforce damages pursuant to any other Section hereof or under applicable law.

            (ii) In addition to any other rights available to the Holder, if the
Obligor fails to deliver to the Holder such certificate or certificates pursuant
to Section 3(a)(i)(A) by the fifth (5th) Trading Day after the Conversion Date,
and if after such fifth (5th) Trading Day the Holder purchases (in an open
market transaction or otherwise) Common Stock to deliver in satisfaction of a
sale by such Holder of the Underlying Shares which the Holder anticipated
receiving upon such conversion (a "Buy-In"), then the Obligor shall (A) pay in
cash to the Holder (in addition to any remedies available to or elected by the

                                       6
<PAGE>

Holder) the amount by which (x) the Holder's total purchase price (including
brokerage commissions, if any) for the Common Stock so purchased exceeds (y) the
product of (1) the aggregate number of shares of Common Stock that such Holder
anticipated receiving from the conversion at issue multiplied by (2) the market
price of the Common Stock at the time of the sale giving rise to such purchase
obligation and (B) at the option of the Holder, either reissue a Debenture in
the principal amount equal to the principal amount of the attempted conversion
or deliver to the Holder the number of shares of Common Stock that would have
been issued had the Obligor timely complied with its delivery requirements under
Section 3(a)(i)(A). For example, if the Holder purchases Common Stock having a
total purchase price of $11,000 to cover a Buy-In with respect to an attempted
conversion of Debentures with respect to which the market price of the
Underlying Shares on the date of conversion was a total of $10,000 under clause
(A) of the immediately preceding sentence, the Obligor shall be required to pay
the Holder $1,000. The Holder shall provide the Obligor written notice
indicating the amounts payable to the Holder in respect of the Buy-In.

      (c) (i) The Holder is entitled, at its option, to convert, and sell on the
same day, at any time, until payment in full of this Debenture, all or any part
of the principal amount of the Debenture, plus accrued interest, into shares of
the Company's common stock, par value $0.001 per share, at the price per share
equal to the lesser of (a) $0.05 (the "Fixed Price"), or (b) an amount equal to
ninety five percent (95%) of the lowest Closing Bid Price of the Company's
Common Stock, as quoted by Bloomberg, LP (the "Closing Bid Conversion Price"),
for the thirty (30) trading days immediately preceding the Conversion Date (as
defined herein), which may be adjusted pursuant to the other terms of this
Debenture. Subparagraphs (a) and (b) above are individually referred to as a
"Conversion Price."

            (ii) If the Obligor, at any time while this Debenture is
outstanding, shall (a) pay a stock dividend or otherwise make a distribution or
distributions on shares of its Common Stock or any other equity or equity
equivalent securities payable in shares of Common Stock, (b) subdivide
outstanding shares of Common Stock into a larger number of shares, (c) combine
(including by way of reverse stock split) outstanding shares of Common Stock
into a smaller number of shares, or (d) issue by reclassification of shares of
the Common Stock any shares of capital stock of the Obligor, then the Fixed
Price shall be multiplied by a fraction of which the numerator shall be the
number of shares of Common Stock (excluding treasury shares, if any) outstanding
before such event and of which the denominator shall be the number of shares of
Common Stock outstanding after such event. Any adjustment made pursuant to this
Section 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, combination or re-classification.

            (iii) If the Obligor, at any time while this Debenture is
outstanding, shall issue rights, options or warrants to all holders of Common
Stock (and not to the Holder) entitling them to subscribe for or purchase shares
of Common Stock at a price per share less than the Fixed Price, then the Fixed
Price shall be multiplied by a fraction, of which the denominator shall be the
number of shares of the Common Stock (excluding treasury shares, if any)
outstanding on the date of issuance of such rights or warrants (plus the number
of additional shares of Common Stock offered for subscription or purchase), and
of which the numerator shall be the number of shares of the Common Stock
(excluding treasury shares, if any) 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 the Fixed Price. Such
adjustment shall be made whenever such rights or warrants are issued, and shall
become effective immediately after the record date for the determination of

                                       7
<PAGE>

stockholders entitled to receive such rights, options or warrants. However, upon
the expiration of any such right, option or warrant to purchase shares of the
Common Stock the issuance of which resulted in an adjustment in the Fixed Price
pursuant to this Section, if any such right, option or warrant shall expire and
shall not have been exercised, the Fixed Price shall immediately upon such
expiration be recomputed and effective immediately upon such expiration be
increased to the price which it would have been (but reflecting any other
adjustments in the Fixed Price made pursuant to the provisions of this Section
after the issuance of such rights or warrants) had the adjustment of the Fixed
Price made upon the issuance of such rights, options or warrants been made on
the basis of offering for subscription or purchase only that number of shares of
the Common Stock actually purchased upon the exercise of such rights, options or
warrants actually exercised.

            (iv) If the Obligor or any subsidiary thereof, as applicable, at any
time while this Debenture is outstanding, shall issue shares of Common Stock or
rights, warrants, options or other securities or debt that are convertible into
or exchangeable for shares of Common Stock ("Common Stock Equivalents")
entitling any Person to acquire shares of Common Stock, at a price per share
less than the Fixed Price (if the holder of the Common Stock or Common Stock
Equivalent so issued shall at any time, whether by operation of purchase price
adjustments, reset provisions, floating conversion, exercise or exchange prices
or otherwise, or due to warrants, options or rights per share which is issued in
connection with such issuance, be entitled to receive shares of Common Stock at
a price per share which is less than the Fixed Price, such issuance shall be
deemed to have occurred for less than the Fixed Price), then, at the sole option
of the Holder, the Fixed Price shall be adjusted to mirror the conversion,
exchange or purchase price for such Common Stock or Common Stock Equivalents
(including any reset provisions thereof) at issue. Such adjustment shall be made
whenever such Common Stock or Common Stock Equivalents are issued. The Obligor
shall notify the Holder in writing, no later than one (1) business day following
the issuance of any Common Stock or Common Stock Equivalent subject to this
Section, indicating therein the applicable issuance price, or of applicable
reset price, exchange price, conversion price and other pricing terms. No
adjustment under this Section shall be made as a result of issuances and
exercises of options to purchase shares of Common Stock issued for compensatory
purposes pursuant to any of the Obligor's stock option or stock purchase plans.

            (v) If the Obligor, at any time while this Debenture is outstanding,
shall distribute to all holders of Common Stock (and not to the Holder)
evidences of its indebtedness or assets or rights or warrants to subscribe for
or purchase any security, then in each such case the Fixed Price at which this
Debenture shall thereafter be convertible shall be determined by multiplying the
Fixed Price in effect immediately prior to the record date fixed for
determination of stockholders entitled to receive such distribution by a
fraction of which the denominator shall be the Closing Bid Price determined as
of the record date mentioned above, and of which the numerator shall be such
Closing Bid 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 the Common Stock as
determined by the Board of Directors in good faith. In either case the
adjustments shall be described in a statement provided to the Holder of the
portion of assets or evidences of indebtedness so distributed or such

                                       8
<PAGE>

subscription rights applicable to one share of Common Stock. Such adjustment
shall be made whenever any such distribution is made and shall become effective
immediately after the record date mentioned above.

            (vi) 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 its option, (A) convert the then outstanding principal amount, together
with all accrued but unpaid interest and any other amounts then owing hereunder
in respect of this Debenture into the shares of stock and other securities, cash
and property receivable upon or deemed to be held by holders of the Common Stock
following such reclassification or share exchange, and the Holder of this
Debenture shall be entitled upon such event to receive such amount of
securities, cash or property as the shares of the Common Stock of the Obligor
into which the then outstanding principal amount, together with all accrued but
unpaid interest and any other amounts then owing hereunder in respect of this
Debenture could have been converted immediately prior to such reclassification
or share exchange would have been entitled, or (B) require the Obligor to prepay
the outstanding principal amount of this Debenture, plus all interest and other
amounts due and payable thereon. The entire prepayment price shall be paid in
cash. This provision shall similarly apply to successive reclassifications or
share exchanges.

            (vii) The Obligor shall maintain a share reserve of not less than
one percent (100%) of the shares of Common Stock issuable upon conversion of
this Debenture; and within three (3) Business Days following the receipt by the
Obligor of a Holder's notice that such minimum number of Underlying Shares is
not so reserved, the Obligor shall promptly reserve a sufficient number of
shares of Common Stock to comply with such requirement.

            (viii) All calculations under this Section 3 shall be rounded up to
the nearest $0.001 of a share.

            (ix) Whenever the Fixed Price is adjusted pursuant to Section 3
hereof, the Obligor shall promptly mail to the Holder a notice setting forth the
Fixed Price after such adjustment and setting forth a brief statement of the
facts requiring such adjustment.

            (x) If (A) the Obligor shall declare a dividend (or any other
distribution) on the Common Stock; (B) the Obligor shall declare a special
nonrecurring cash dividend on or a redemption of the Common Stock; (C) the
Obligor shall 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; (D) the approval of any stockholders of the Obligor
shall be required in connection with any reclassification of the Common Stock,
any consolidation or merger to which the Obligor is a party, any sale or
transfer of all or substantially all of the assets of the Obligor, of any
compulsory share exchange whereby the Common Stock is converted into other
securities, cash or property; or (E) the Obligor shall authorize the voluntary
or involuntary dissolution, liquidation or winding up of the affairs of the
Obligor; then, in each case, the Obligor shall cause to be filed at each office
or agency maintained for the purpose of conversion of this Debenture, and shall
cause to be mailed to the Holder at its last address as it shall appear upon the
stock books of the Obligor, at least twenty (20) calendar days prior to the

                                       9
<PAGE>

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 the 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 or share exchange is expected to become effective or
close, and the date as of which it is expected that holders of the Common Stock
of record shall be entitled to exchange their shares of the Common Stock for
securities, cash or other property deliverable upon such reclassification,
consolidation, merger, sale, transfer or share exchange, provided, 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. The Holder is entitled to convert this Debenture during the
20-day calendar period commencing the date of such notice to the effective date
of the event triggering such notice.

            (xi) In case of any (1) merger or consolidation of the Obligor or
any subsidiary of the Obligor with or into another Person, or (2) sale by the
Obligor or any subsidiary of the Obligor of more than one-half of the assets of
the Obligor in one or a series of related transactions, a Holder shall have the
right to (A) exercise any rights under Section 2(b), (B) convert the aggregate
amount of this Debenture then outstanding 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 merger, consolidation or sale, and such Holder shall
be entitled upon such event or series of related events to receive such amount
of securities, cash and property as the shares of Common Stock into which such
aggregate principal amount of this Debenture could have been converted
immediately prior to such merger, consolidation or sales would have been
entitled, or (C) in the case of a merger or consolidation, require the surviving
entity to issue to the Holder a convertible Debenture with a principal amount
equal to the aggregate principal amount of this Debenture then held by such
Holder, plus all accrued and unpaid interest and other amounts owing thereon,
which such newly issued convertible Debenture shall have terms identical
(including with respect to conversion) to the terms of this Debenture, and shall
be entitled to all of the rights and privileges of the Holder of this Debenture
set forth herein and the agreements pursuant to which this Debentures were
issued. In the case of clause (C), the conversion price applicable for the newly
issued shares of convertible preferred stock or convertible Debentures shall be
based upon the amount of securities, cash and property that each share of Common
Stock would receive in such transaction and the Conversion Price in effect
immediately prior to the effectiveness or closing date for such transaction. The
terms of any such merger, sale or consolidation shall include such terms so as
to continue to give the Holder the right to receive the securities, cash and
property set forth in this Section upon any conversion or redemption following
such event. This provision shall similarly apply to successive such events.

      (d) The Obligor covenants that it will at all times reserve and keep
available out of its authorized and unissued shares of Common Stock solely for
the purpose of issuance upon conversion of this Debenture and payment of
interest on this Debenture, each as herein provided, free from preemptive rights
or any other actual contingent purchase rights of persons other than the Holder,
not less than such number of shares of the Common Stock as shall (subject to any
additional requirements of the Obligor as to reservation of such shares set
forth in this Debenture) be issuable (taking into account the adjustments and
restrictions of Sections 2(b) and 3(c)) upon the conversion of the outstanding
principal amount of this Debenture and payment of interest hereunder. The

                                       10
<PAGE>

Obligor covenants that all shares of Common Stock that shall be so issuable
shall, upon issue, be duly and validly authorized, issued and fully paid,
nonassessable and, if the Underlying Shares Registration Statement has been
declared effective under the Securities Act, registered for public sale in
accordance with such Underlying Shares Registration Statement.

      (e) Upon a conversion hereunder the Obligor shall not be required to issue
stock certificates representing fractions of shares of the Common Stock, but may
if otherwise permitted, make a cash payment in respect of any final fraction of
a share based on the Closing Bid Price at such time. If the Obligor elects not,
or is unable, to make such a cash payment, the Holder shall be entitled to
receive, in lieu of the final fraction of a share, one whole share of Common
Stock.

      (f) The issuance of certificates for shares of the Common Stock on
conversion of this Debenture shall be made without charge to the Holder thereof
for any documentary stamp or similar taxes that may be payable in respect of the
issue or delivery of such certificate, provided that the Obligor 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 of such Debenture so converted and the Obligor
shall not be required to issue or deliver such certificates unless or until the
person or persons requesting the issuance thereof shall have paid to the Obligor
the amount of such tax or shall have established to the satisfaction of the
Obligor that such tax has been paid.

      (g) Any notices, consents, waivers or other communications required or
permitted to be given under the terms hereof must be in writing and will be
deemed to have been delivered: (i) upon receipt, when delivered personally; (ii)
upon receipt, when sent by facsimile (provided confirmation of transmission is
mechanically or electronically generated and kept on file by the sending party);
or (iii) one (1) trading day after deposit with a nationally recognized
overnight delivery service, in each case properly addressed to the party to
receive the same. The addresses and facsimile numbers for such communications

acquire shares of its Common Stock or other equity securities other than as to
the Underlying Shares to the extent permitted or required under the Transaction
Documents; or (iii) enter into any agreement with respect to any of the
foregoing.

      Section 6. This Debenture shall not entitle the Holder to any of the
rights of a stockholder of the Obligor, including without limitation, the right
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
Obligor, unless and to the extent converted into shares of Common Stock in
accordance with the terms hereof.

      Section 7. If this Debenture is mutilated, lost, stolen or destroyed, the
Obligor shall execute and deliver, in exchange and substitution for and upon
cancellation of the 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 Obligor.

      Section 8. No indebtedness of the Obligor is senior to this Debenture in
right of payment, whether with respect to interest, damages or upon liquidation
or dissolution or otherwise. Without the Holder's consent, the Obligor will not
and will not permit any of their subsidiaries to, directly or indirectly, enter
into, create, incur, assume or suffer to exist any indebtedness of any kind, on
or with respect to any of its property or assets now owned or hereafter acquired
or any interest therein or any income or profits there from that is senior in

      Section 9. This Debenture shall be governed by and construed in accordance
with the laws of the State of New Jersey, without giving effect to conflicts of
laws thereof. Each of the parties consents to the jurisdiction of the Superior
Courts of the State of New Jersey sitting in Hudson County, New Jersey and the
U.S. District Court for the District of New Jersey sitting in Newark, New Jersey
in connection with any dispute arising under this Debenture and hereby waives,
to the maximum extent permitted by law, any objection, including any objection
based on forum non conveniens to the bringing of any such proceeding in such
jurisdictions.

      Section 10. If the Obligor fails to strictly comply with the terms of this
Debenture, then the Obligor shall reimburse the Holder promptly for all fees,
costs and expenses, including, without limitation, attorneys' fees and expenses
incurred by the Holder in any action in connection with this Debenture,
including, without limitation, those incurred: (i) during any workout, attempted
workout, and/or in connection with the rendering of legal advice as to the
Holder's rights, remedies and obligations, (ii) collecting any sums which become
due to the Holder, (iii) defending or prosecuting any proceeding or any
counterclaim to any proceeding or appeal; or (iv) the protection, preservation
or enforcement of any rights or remedies of the Holder.

      Section 11. Any waiver by 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

                                       14
<PAGE>

Debenture. The failure of 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 12. 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. If it shall be found
that any interest or other amount deemed interest due hereunder shall violate
applicable laws governing usury, the applicable rate of interest due hereunder
shall automatically be lowered to equal the maximum permitted rate of interest.
The Obligor covenants (to the extent that it may lawfully do so) that it shall
not at any time insist upon, plead, or in any manner whatsoever claim or take
the benefit or advantage of, any stay, extension or usury law or other law which
would prohibit or forgive the Obligor from paying all or any portion of the
principal of or interest on this Debenture as contemplated herein, wherever
enacted, now or at any time hereafter in force, or which may affect the
covenants or the performance of this indenture, and the Obligor (to the extent
it may lawfully do so) hereby expressly waives all benefits or advantage of any
such law, and covenants that it will not, by resort to any such law, hinder,
delay or impeded the execution of any power herein granted to the Holder, but
will suffer and permit the execution of every such as though no such law has
been enacted.

      Section 13. 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.

      Section 14. THE PARTIES HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY
WAIVE THE RIGHT ANY OF THEM MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY
LITIGATION BASED HEREON OR ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS
AGREEMENT OR ANY TRANSACTION DOCUMENT OR ANY COURSE OF CONDUCT, COURSE OF
DEALING, STATEMENTS (WHETHER VERBAL OR WRITTEN) OR ACTIONS OF ANY PARTY. THIS
PROVISION IS A MATERIAL INDUCEMENT FOR THE PARTIES' ACCEPTANCE OF THIS
AGREEMENT.
