                      (vi) The Company acknowledges and agrees that its has
advised the Holder in good faith that it expects based upon its present forecast
of sales to reduce the principal amount of this Note to zero in three years or

1(a) and 1(b) hereof. The Holder acknowledges that the foregoing is a forecast
and is not binding upon the Company. The Company covenants to use reasonable
commercial efforts to increase the sale of Test Units. Notwithstanding the
foregoing, nothing herein shall obligate the Company to continue to market and
sell Test Units, but in the event that the Company should cease, voluntarily or
involuntarily, to sell Test Units in any three month period at any annualized
volume of less than $1,000,000, or in the event that the Company's sale of Test
Units shall otherwise result in the Holder receiving payments hereunder in any
three month period of less than $50,000, the Holder reserves the right to
declare this Note due and payable in full; provided, however, the Holder shall
not be entitled to exercise any of its rights as a secured creditor hereunder in
the event of such a declaration by the Holder.

               (c) Proceeds from Sale of Stock.

                      (i) If the Company receives proceeds from the sale of any
of its Additional Common Stock (as hereinafter defined), the Company shall pay
the following proceeds to the Holder, to be applied to the principal balance of
the Note: (x) in the event that the Adjusted Per Share Price (as hereafter
defined) shall be $0.75 or more, an amount equal to 10% of the Adjusted Per
Share Price; and (y) in the event that the Adjusted Per Share Price shall be
less than $0.75, an amount equal to 15% of the Adjusted Per Share Price.

                      (ii) Payment of the foregoing amount shall be paid within
thirty (30) business days of the receipt by the Company of any such proceeds.

               (d) Multiple Payment Obligations. The Company's payment
obligations under this Section 1 are cumulative and not mutually exclusive, and

Section 1 hereof shall not postpone or otherwise relieve the Company of the
obligation of making payment under the other provisions of this Section 1.

        2. Conversion.

               (a) Optional Conversion Right. Subject to the terms and
conditions of Section 2(b) and Section 2(c) hereof, during the period ending
with the 18th month anniversary of this Note (the "Conversion Period"), Holder
may, at its option, at any time and from time to time, convert (the "Conversion
Right") the unpaid principal balance of this Note, in whole or in part, into
shares of the Company's Common Stock, par value $0.01 per share (the "Conversion
Shares"), based upon a price (the "Conversion Price") of $0.40 per Conversion
Share, subject to adjustment as provided in Section 2(e) hereof. By way of
example but not by way of limitation, if this Conversion Right were to be
exercised as of the date hereof, Holder would receive 1,578,783 Conversion
Shares ($631,513.37 / $0.40).

               (b) Shortening of Conversion Period. The Company may advise the
Holder in writing (a "Milestone Share Price Notice") at such time that the Per
Share Price of the Company's Common Stock at which it is Publicly Traded (as
hereinafter defined)

                                       45
<PAGE>

shall have reached or exceeded an Average Per Share Price of $2.00 during any
period of 30 Consecutive Trading Days (as hereinafter defined) in which this
Note remains outstanding. Notwithstanding anything in Section 2(a) to the
contrary, the Conversion Period shall expire 30 days after the Holder's receipt
of the Milestone Share Price Notice. For purposes of this Section 2(b), (i) the
term "Per Share Price of the Company's Common Stock at which it is Publicly
Traded" shall mean the closing price per share of the Common Stock of the
Company as quoted on the Pink Sheets (R) LLC (the "Pink Sheets") or, in the
event that the Company's Common Stock shall not then be quoted on the Pink
Sheets, on such other quoting medium or trading exchange as the Common Stock is
then quoted or traded; and (ii) the term "Trading Days" shall mean days on which
there shall be a quotation for the Company's Common Stock on the Pink Sheets or
other quoting medium on which the Company's common Stock is then quoted or a
trade indicated on such other exchange as the Company's Common Stock is then
traded. The Company's right to shorten the Conversion Period shall fail to arise
if the Company shall fail to deliver the Milestone Share Price Notice even if in
fact the Per Share Price of the Company's Common Stock at which it is Publicly
Traded shall have reached or exceeded an Average Per Share Price of $2.00 during
any period of 30 Consecutive Trading Days.

               (c) Mechanics and Condition of Conversion. The Holder may
exercise its conversion rights under Section 2(a) hereof by written notice to
the Company (the "Conversion Notice") stating that the Holder elects to convert
some or all of the principal amount of this Note, and specifying the amount to
be converted (the "Conversion Amount"). In the event that the Holder elects to
convert the remaining principal balance of this Note, the Holder shall at the
time of delivering the Conversion Notice also surrender this Note. Conversion
shall be considered to have been effective on the date when the Conversion
Notice is received by the Company (the "Conversion Date") for the Conversion
Amount unless, within thirty (30) days after the Conversion Date, the Company
shall deliver to the Holder a certified check in any amount (the "Conversion
Stopping Payment") up to the Conversion Amount, in which case Holder's
conversion right as to the amount of the Conversion Stopping Payment shall be
lost. To the extent to which the Company fails to make a Conversion Stopping
Payment that is less than the Conversion Amount prior to the expiration of such
30 day period, then, not later than 20 days after the expiration of such 30 day
period, the Company shall issue and deliver to the Holder a certificate or
certificates for the number of Conversion Shares as is derived by dividing (x)
the difference between the Conversion Amount and the Conversion Stopping Payment
by (y) $0.40 (subject to adjustment as provided for elsewhere herein).

               (d) Fractional Interests. The Company shall not be required to
issue fractional Conversion Shares on the conversion of this Note. If any
fractions of a Conversion Share would, except for the provision of this
subsection, be issued upon the exercise of Holder's Conversion Right hereunder,
the Company will: (i) if the fraction of a Conversion Share otherwise issuable
is equal to or less than one-half, round down and issue to the Holder only the
largest whole number of Conversion Shares to which the Holder is otherwise
entitled; or (ii) if the fraction of a Conversion Share otherwise issuable is
greater than one-half, round up and issue to the Holder an additional Conversion
Share in addition to the largest whole number of Conversion Shares to which the
Holder is otherwise entitled.

               (e) Adjustments. The number of Conversion Shares purchasable upon
conversion of this Note and the Conversion Price shall be subject to adjustment
as follows:

                                       46
<PAGE>

                      (i) Stock Dividends, Stock Splits, Etc. In case the
Company shall at any time after the date of this Note (A) declare or pay a
dividend in shares of Common Stock (as hereinafter defined) or make a
distribution in shares of Common Stock, (B) subdivide its outstanding shares of
Common Stock, (C) combine its outstanding shares of Common Stock into a smaller
number of shares of Common Stock or (D) issue any shares of its capital stock in
a reclassification of the Common Stock (including any such reclassification in
connection with a consolidation or merger in which the Company is the continuing
entity), the number of Conversion Shares purchasable upon conversion of this
Note immediately prior thereto shall be adjusted so that the Holder shall be
entitled to receive the kind and number of Conversion Shares or other securities
of the Company which it would have owned or have been entitled to receive after
the happening of any of the events described hereinabove, had the Note been
converted immediately prior to the happening of such event or any record date
with respect thereto.

                      (ii) De Minimus Adjustment. No adjustment in the number of
Conversion Shares purchasable hereunder shall be required unless such adjustment
would result in an increase or decrease of at least one percent (1%) of the
Conversion Price; provided, however, that any adjustments which by reason of
this Section 2(e)(ii) are not required to be made shall be carried forward and
taken into account in any subsequent adjustment.

                      (iii) Conversion Price Adjustment. Whenever the number of
Conversion Shares purchasable upon the conversion of this Note is adjusted, as
herein provided, the Conversion Price payable upon purchase of each Conversion
Share shall be adjusted by multiplying such Conversion Price immediately prior
to such adjustment by a fraction, of which the numerator shall be the number of
Conversion Shares purchasable upon the conversion of this Note immediately prior
to such adjustment, and of which the denominator shall be the number of
Conversion Shares purchasable immediately thereafter.

                      (iv) Preservation of Purchase Rights Upon Merger,
Consolidation, Etc. In case of any merger, reorganization or consolidation of
the Company into another corporation or entity other than a subsidiary of the
Company (a "Merger"), or in case of any sale of all, or substantially all, of
the assets of the Company or any subsidiary of the Company (a "Sale of Assets"),
the Company or such successor or purchasing entity or corporation, as the case
may be, shall execute with Holder an agreement that the Holder shall have the
right thereafter to purchase upon conversion of the Note the kind and amount of
Conversion Shares and other securities and property which it would have owned or
have been entitled to receive after the happening of such Merger or Sale of
Assets had such Note been converted immediately prior to such action. Such
agreement shall provide for adjustments, which shall be as nearly equivalent as
may be practicable to the adjustments provided for in this Section 2(e). The
provisions of this Section 2(e)(iv) shall similarly apply to successive Mergers
and Sales of Assets.

               (f) Common Stock. For the purpose of this Note, the term "shares
of Common Stock " or "Common Stock" shall mean (i) the class of stock designated
as the Common Stock of the Company at the date of this Note, or (ii) any other
class of stock resulting from successive changes or reclassifications of such
shares consisting solely of changes in par value, or from par value to no par
value, or from no par value to par value. In the event that at any time, as a
result of an adjustment made pursuant to this Section 2, the Holder shall become
entitled to purchase any securities of the Company other than shares of Common
Stock, thereafter the number of such other securities so purchasable upon
conversion of this Note and

                                       47
<PAGE>

the Conversion Price of such securities shall be subject to adjustment from time
to time in a manner and on terms as nearly equivalent as practicable to the
provisions with respect to the Conversion Shares referred to in Section 2 (a)
hereof.

        3. Escrow Shares.

               (a) In order to induce Company to utilize its resources to repay
the principal indebtedness evidenced by this Note as quickly as possible, the
Company agrees to establish an escrow (the "Escrow") to be maintained by the
Company's counsel, Bryan Cave LLP (the "Escrow Agent") consisting of
certificates representing an aggregate of three hundred thousand (300,000)
shares of Common Stock (the "Escrow Shares"), the registration for which shall
initially be in blank but which shall be completed by the Escrow Agent in
accordance with the provisions hereof.

               (b) Subject to Section 6 hereof, the Escrow Shares shall be
released from the Escrow as follows:

                      (i) If the principal amount of this Note shall be reduced
to zero prior to the first anniversary of this Note, the Escrow Agent shall
deliver to the Company all of the certificates representing the Escrow Shares,
and the Holder shall not be deemed to be entitled to any of the Escrow Shares;

                      (ii) If the principal amount of this Note shall be reduced
to zero after the first anniversary of this Note but prior to the 18th month
anniversary of this Note, the Escrow Agent shall deliver to the Company
certificates representing 225,000 of the Escrow Shares and shall deliver to the
Holder a certificate representing 75,000 of the Escrow Shares;

                      (iii) If the principal amount of this Note shall be
reduced to zero after the 18th month anniversary of this Note but prior to the
24th month anniversary of this Note, the Escrow Agent shall deliver to the
Company certificates representing 150,000 of the Escrow Shares and shall deliver
to the Holder a certificate representing 150,000 of the Escrow Shares; and

                      (iv) If the principal amount of this Note shall be reduced
to zero after the 24th month anniversary of this Note but prior to the 30th
month anniversary of this Note, the Escrow Agent shall deliver to the Company
certificates representing 100,000 of the Escrow Shares and shall deliver to the
Holder a certificate representing 200,000 of the Escrow Shares. [Randy--I took
out the 30-36 month slug; Dan and I specifically spoke of this, and the earlier
figures took into account that we would not provide for this earlier slug]

                      (v) If the Company shall fail to reduce the principal
amount of this Note to zero prior to the 30th month anniversary of this Note,
the Escrow Agent shall deliver to the Holder a certificate representing 300,000
of the Escrow Shares.

               (c) The Escrow Agent shall deliver certificates representing the
Escrow Shares in the amounts set forth above to the party or parties, as the
case may be, not later than 20 days after being advised by the parties that the
principal amount of the Note shall have been reduced to zero; provided, however,
that in the event the principal amount shall not have been reduced to zero prior
to the 30th month anniversary of this Note, the Escrow Agent shall

                                       48
<PAGE>

deliver certificates representing the Escrow Shares to the Holder not later than
20 days after being so advised by the Holder.

               (d) The Escrow Agent shall be deemed authorized and directed to
complete on the certificates representing any of the Escrow Shares the name of
the party or parties, as the case may be, to whom the certificates shall be
issued, as well as the number of Escrow Shares to be represented by such
certificates, consistent with the provisions of Section 3(b) of this Note.

               (e) The Escrow Shares shall not be deemed to be issued and
outstanding shares of the Company until such time as the Escrow Agent shall be
obligated to deliver certificates representing the Escrow Shares pursuant to the
terms hereof.

               (f) The Holder acknowledges that the Escrow Agent is counsel to
the Company and acknowledges and agrees that the Escrow Agent may continue to
represent the Company in all matters including without limitation matters
involving this Note and the indebtedness represented hereby, save only as may
pertain to any dispute arising out of the Escrow Agent's obligations under this
Section 3. The Holder acknowledges that Escrow Agent's duties to it are limited
to those expressly set forth in Section 3 of this Note.

               (g) The parties do not intend the indebtedness hereunder, which
arose in the course of the sale and purchase of product, to constitute a "loan"
to the Company by the Holder for purposes of Internal Revenue Code Section 7872
and the regulations thereunder. However, in the event that the indebtedness
hereunder shall be determined by the Internal Revenue Service to be a loan to
the Company by the Holder under the applicable provisions of the Internal
Revenue Code, the parties acknowledge the uncertain value of the Escrow Shares
and agree that the actual value of such Escrow Shares, if any, at the time of
their issuance to the Holder shall not be determinative of any imputed interest
rate; and in such eventuality, the parties agree that the applicable interest
rate for the indebtedness hereunder shall be 7.0%, which is the New Jersey
statutory rate of post-judgment rate of interest, which shall be calculated by
reducing, on a dollar-for-dollar basis, the original principal amount of this
Note that the Holder is deemed to have been paid under the terms hereof. Nothing
in the provisions of this Section 3(g) shall be deemed to otherwise affect the
characterization of the indebtedness owed by the Company to the Holder under
this Note.

               4. Security Interest; Subordination.

               (a) To secure payment and performance of the Company's duties and
obligations under this Note, and subject to the terms of Section 4(d) hereof,
the Company hereby pledges, assigns, transfers and grants to the Holder the
following two, continuing security interests: (i) a continuing security interest
in "Company Property" (as hereinafter defined); and (ii) a continuing security
interest in 1,515,000 shares of Common Stock (the "Collateral Shares") which
shares of Common Stock are separate and apart from and in addition to those
shares of Common Stock referenced by Section 2 and/or any other Section hereof.
These two, continuing security interests are granted in accordance with that
certain Security Agreement between the parties attached hereto as Exhibit B (the
"Security Agreement"), the terms of which are incorporated herein by reference
and in connection with which the Company hereby delivers (x) to the Holder,
Uniform Commercial Code financing statements which the Holder is hereby

                                       49
<PAGE>

authorized to file and (y) to Bryan Cave LLP as collateral agent (the
"Collateral Agent") a certificate representing the Collateral Shares.

               (b) For purposes of this Section 4, the term "Company Property"
shall have such definition as is set forth in the Security Agreement.

               (c) As set forth in the Security Agreement, the Holder's right to
exercise its rights as a secured creditor of the Company in respect of Company
Property does not arise until there is an Event of Default that is of a nature
that is expressly set forth in Section 5 (b), 5(c), 5(d), or 5(e) hereof, and
except for the foregoing, the Holder shall not be entitled to exercise its
rights as a secured creditor of the Company in respect of Company Property. The
Holder's right to exercise its rights as a secured creditor of the Company in
respect of the Collateral Shares arises upon any Event of Default under Section
5 hereof.

               (d) The indebtedness evidenced by this Note, and the security
interest granted hereby, shall be junior and subordinate only to bank or other
institutional indebtedness of the Company not to exceed $300,000 in principal
amount (the "Senior Debt"). The Company agrees that if, during any time that
this Note remains outstanding, any bank or other institutional lender
(hereinafter collectively referred to as "Other Lender") extends credit to
Company in excess of $300,000, then Company shall require such Other Lender to
execute and deliver for the benefit of Holder any subordination agreement that
is requested by and reasonably acceptable to Holder to evidence the
subordination of the indebtedness to such Other Lender to Company's obligations
to Holder under this Note. The Holder agrees from time to time to execute such
documents as the Company may reasonably request in order to subordinate the
indebtedness hereunder to the Senior Debt.

               (e) The Collateral Agent shall be deemed authorized and directed
to complete the name of the Holder on the certificates representing any of the
Collateral Shares as to which the Holder shall be entitled in an Event of
Default, as well as the number of shares to be represented by such certificates,
consistent with the provisions of this Agreement and the Security Agreement.

               (f) The Collateral Shares shall not be deemed to be issued and
outstanding shares of the Company until such time as the Collateral Agent shall
be obligated to deliver certificates representing the Collateral Shares pursuant
to the terms hereof.

               (g) The Holder acknowledges that the Collateral Agent is counsel
to the Company and acknowledges and agrees that the Collateral Agent may
continue to represent the Company in all matters including without limitation
matters involving this Note and the indebtedness represented hereby, save only
as may pertain to any dispute arising out of the Collateral Agent's obligations
under this Section 4. The Holder acknowledges that Collateral Agent's duties to
it are limited to those expressly set forth in Section 4 of this Note.

        5. Default.

        The entire unpaid principal of this Note and all of the Escrow Shares
shall become and be immediately due and payable and issuable upon written demand
of Holder, without any other notice (except as may otherwise be set forth
hereinbelow) or demand of any kind or any presentment or protest, if any one of
the following events (each an "Event of Default") shall

                                       50
<PAGE>

occur and be continuing at the time of such demand, whether voluntarily or
involuntarily, or, without limitation, occurring or brought about 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 governmental body:

               (a) If the Company defaults in the payment of any principal due
under this Note, and any default shall remain unremedied for fifteen (15) days
after written notice of default shall have been received by the Company;

               (b) If the Company (i) makes a composition or an assignment for
the benefit of creditors or trust mortgage, (ii) applies for, consents to,
acquiesces in, files a petition seeking or admits (by answer, default or
otherwise) the material allegations of a petition filed against it seeking the
appointment of a trustee, receiver or liquidator, in bankruptcy or otherwise, of
itself or of all or a substantial portion of its assets, or a reorganization,
arrangement with creditors or other remedy, relief or adjudication available to
or against a bankrupt, insolvent or debtor under any bankruptcy or insolvency
law or any law affecting the rights of creditors generally, or (iii) admits in
writing its inability to pay its debts generally as they become due;

               (c) If an order for relief shall have been entered by a
bankruptcy court or if a decree order or judgment shall have been entered
adjudging the Company insolvent, or appointing a receiver, liquidator, custodian
or trustee, in bankruptcy or otherwise, for it or for all or a substantial
portion of its assets, or approving the winding-up or liquidation of its affairs
on the grounds of insolvency or nonpayment of debts, and such order for relief,
decree, order or judgment shall remain undischarged or unstayed for a period of
forty-five (45) days; or if any substantial part of Company Property is
sequestered or attached and shall not be returned to the possession of the
Company or such subsidiary or released from such attachment within forty-five
(45) days;

               (d) If the Company is dissolved or liquidated;

               (e) If an Acquisition Event occurs ("Acquisition Event" shall
mean: (a) any merger or consolidation which results in the voting securities of
the Company outstanding immediately prior thereto representing immediately
thereafter (either by remaining outstanding or by being converted into voting
securities of the surviving or acquiring entity) less than a majority of the
combined voting power of the voting securities of the Company or such surviving
or acquiring entity outstanding immediately after such merger or consolidation;
(b) any sale of all or substantially all of the assets of the Company; or (c)
sale of shares of capital stock of the Company, in a single transaction or
series of related transactions, representing at least 80% of the voting
securities of the Company);

               (f) If a default occurs under any material ($50,000 or more)
promissory note or other evidence of indebtedness of the Company for borrowed
money, or under any indenture or other instrument under which any such
promissory note or other evidence of indebtedness has been issued or by which it
is governed, and the expiration of the applicable period of grace, if any,
specified in such promissory note, evidence of indebtedness, indenture or
agreement, in each case only if such default shall not have been remedied by the
end of the 15th day after written notice of default shall have been received by
the Company (which notice shall not be sent until the expiration of the
applicable period of grace, if any); provided, however, that if such default
under such promissory note, evidence of indebtedness, indenture or agreement

                                       51
<PAGE>

shall be cured by the Company or waived by the holder of such indebtedness in
each case as may be permitted by the express terms of such promissory note,
evidence of indebtedness, indenture or agreement, then the Event of Default
hereunder by reason of such default shall be deemed likewise to have been
thereupon cured or waived;

               (g) If any representation or warranty made by the Company in
Section 3 of the Security Agreement shall prove to have been incorrect in any
material respect when made, if the same shall materially impair the Holder's
rights under this Note or the Security Agreement; or

               (h) If the Company shall fail to perform or observe any term,
covenant or agreement on its part to be performed or observed as contained in
Section 4 or 5 of the Security Agreement, in each case only if such breach or
default shall not have been remedied by the end of the 15th day after written
notice of breach or default shall have been received by the Company.

        6. Veto Power and Waiver Thereof. In accordance with Article III Section
8 of Company's By-Laws, the President of the Holder, Jemo Kang, in his capacity
as a director of the Company, has the right to veto certain decisions of the
Board of Directors relating to certain officers and other key persons associated
with the Company (the "Veto Right"). By execution of this Note where indicated
below, Jemo Kang hereby agrees that he may not exercise the Veto Right from and
after such date on which the Company shall have tendered an aggregate of
$100,000 in reduction of the principal balance of this Note; provided, however,
that Jemo Kang may exercise the Veto Right following a "Veto Event of Default"
under this Note unless and until the Company has reduced the principal amount of
this Note to less than $256, 513.37.2

        7. Prepayment. The Company shall have the right to prepay this Note, in
whole or in part, at any time without penalty or premium. But, in no event,
shall such prepayment postpone or otherwise delay any subsequent payments that
may be due. In the event that the Company shall choose to prepay this Note, in
whole or in part, and, shall tender immediate payment to the Holder therefor,
the Holder shall be precluded from exercising its conversion rights, as set
forth in Section 2 above, in respect of such principal prepayment amount; in the
event that the Company shall choose to prepay this Note, in whole or in part,
and, in lieu of tender of immediate payment, shall so notify the Holder thereof,
the Holder shall be precluded from exercising its conversion rights, as set
forth in Section 2 above, in respect of such principal prepayment amount during
the thirty (30)-day period immediately following the date of such notice.

------------------
(2)   A Veto Event of Default shall mean either or both of (i) a failure by the
      Company to provide an Explanation of Payment for two consecutive weeks
      (whether or not the Company tenders the relevant Weekly Payment), if, and
      only if, thereafter the Holder shall provide written notification to the
      Company of such failure to provide Explanations of Payment in the manner
      provided in Section 8(h) hereof, and the Company shall not, within 15
      calendar days after deemed delivery of the notice, provide to the Holder
      such Explanations of Payment as referenced in such notice or (ii) a
      failure by the Company to tender Weekly Payments, if, and only if, the
      aggregate value thereof shall be not less than $25,000, and, following the
      occurrence of such event, the Holder shall provide written notification to
      the Company of such failure to tender Weekly Payments in the manner
      provided in Section 8(h) hereof, and the Company shall not, within 30
      calendar days after deemed delivery of such notice, provide to the Holder
      such aggregate Weekly Payments as referenced in such notice.

        8. General

               (a) Upon receipt by the Company of evidence reasonably
satisfactory to it of the loss, theft, destruction or mutilation of this Note
and of indemnity reasonably satisfactory to it, and upon reimbursement to the
Company of all reasonable expenses incidental thereto, and upon surrender and
cancellation of this Note (in case of mutilation) the Company will make and
deliver in lieu of this Note a new Note of like tenor and unpaid principal
amount and dated as of the date to which interest has been paid on the unpaid
principal amount of this Note in lieu of which such new Note is made and
delivered.

               (b) Designees for Shares. The Holder may designate persons other
than the Holder in whose names the Conversion Shares, the Escrow Shares or the
Collateral Shares may be registered and issued.

               (c) Absence of Registration. The Holder acknowledges that none of
the Conversion Shares, the Escrow Shares nor the Collateral Shares are
registered under the Securities Act of 1933, as amended, and agrees the Company
shall have the right to require the Holder to furnish such representations and
warranties as to the Holder's investment intent as are reasonable and customary
in the issuance of unregistered stock.

               (d) Reservation of Shares. The Company represents and warrants
that it has reserved out of the authorized and unissued shares of Common Stock a
number of Conversion Shares sufficient to provide for the exercise of the
Conversion Right provided for by Section 2 hereof.

               (e) Successors and Assigns. This Note, and the obligations and
rights of the Company hereunder, shall be binding upon and inure to the benefit
of the Company, Holder, and their respective successors and assigns.

               (f) Changes and Indulgences. Changes in or additions to this Note
may be made or compliance with any term, covenant, agreement, condition or
provision set forth herein may be omitted or waived (either generally or in a
particular instance and either retroactively or prospectively), only upon
written consent of the Company and the Holder. Neither the failure nor any delay
on the part of either Holder or the Company to exercise any right, remedy, power
or privilege under this Note shall operate as a waiver thereof, nor shall any
single or partial exercise of any right, remedy, power or privilege preclude any
other or further exercise of the same or of any other right, remedy, power or
privilege; nor shall any waiver of any right, remedy, power or privilege
constitute a waiver with respect to any other occurrence.

               (g) Currency. Except as otherwise set forth or expressly provided
for herein, all payments hereunder shall be made in such coin or currency of the
United States of America as at the time of payment shall be legal tender therein
for the payment of public and private debts.

               (h) Notices. All notices, requests, consents and demands shall be
made in writing and shall be delivered by facsimile to the fax number, if any,
set forth below or by hand, sent via a reputable nationwide overnight courier

be retained by the Company for a period of not less than four years after the
date on which the principal indebtedness evidenced by this Note is paid in full,
or such longer period if required by state statute; but, the expiration of such
four-year period shall not limit the remedies available to Holder in any way and
the disposal of such records at the end of the foregoing four-year period shall
be at the Company's risk.

               (k) Governing Law. This Note shall be construed and enforced in
accordance with, and the rights of the parties shall be governed by, the laws of
the State of California,

                                       54
<PAGE>

notwithstanding any conflict-of-laws doctrines of such state or other

of law requiring constructions against the draftsman. The parties agree to
submit to the jurisdiction and venue of the state and federal courts of Orange
County, California, for the purposes of resolving disputes hereunder and
authorize any such action to be instituted and prosecuted exclusively in the
Superior Court of the State of New Jersey or, if appropriate, the United States
District Court for the Central District of California.

               (l) Conflict. In the event of any conflict between the terms of

Conversion Shares or Escrow Shares as provided for herein.

               (n) Severability. If any provision of this Note is held invalid
or unenforceable, such invalidity or unenforceability shall not affect the
validity or enforceability of the other provisions of this Note, all of which
are declared severable.

               (o) Headings. The headings used in this Note are solely for
convenience of reference and shall not affect its interpretation.

appears appropriate, each term stated in either the singular or the plural shall

feminine or neuter gender, shall include the masculine, feminine and neuter.

               (r) Certain Persons. The Company acknowledges that the President
of the Holder, Jemo Kang, is a director of the Company, and that the Holder has
been represented in the preparation of this Note by a law firm, Fox Rothschild
O'Brien & Frankel LLP ("Fox Rothschild"), a partner of which, Jeffrey H.
Nicholas, is a director of the Company. The Company waives the right to claim
the lack of enforceability or the voidness or voidability of this Note as a
result of the involvement of Dr. Kang and Mr. Nicholas, and agrees, represents
and warrants that the terms of this Note have been approved by a majority of the
disinterested directors of the Company (with Dr. Kang and Mr. Nicholas not
constituting disinterested directors for these purposes) in accordance with the
provisions of Section 144(a) of the Delaware General Business Corporation Law.
The Company agrees to raise no objection to the continued representation of the
Holder and Dr. Kang by Fox Rothschild (which term as used in this subsection
shall include Mr. Nicholas) in matters involving this Note and the indebtedness
represented hereby inclusive of the Exhibits and related agreements entered into
in connection herewith, it being understood that such agreement by the Company
does not constitute a waiver

                                       55
<PAGE>

or release by the Company or any of its stockholders of fiduciary duties owed to
the Company by Mr. Nicholas.

               (s) Entire Understanding. This Note contains the entire
understanding among the parties hereto with respect to the subject matter
hereof, and supercedes all prior and contemporaneous agreements and
understandings, inducements or conditions, express or implied, oral or written,
except as herein contained. The express terms hereof control and supersede any
course of performance and/or usage of the trade inconsistent with any of the
terms hereof.

        IN WITNESS WHEREOF, the Company has caused this Note to be executed on
its behalf by its duly authorized officer on May 8, 2001, to be effective as of
the date first above written.
