and existing under the laws of California (the "Company"), designated as its 12%
Subordinated Convertible Debenture Due February 23, 2001 (the "Debenture").

     FOR VALUE RECEIVED, the Company promises to pay to Britannica Associates

Hundred Thousand Dollars (US$500,000) on February 23, 2001 (the "Maturity Date")

the Holder of this Debenture by check if paid more than ten days prior to the

<PAGE>

     This Debenture is subject to the following additional provisions:

     1. The Debenture is issuable in denominations of Fifty Thousand Dollars
(US$50,000) and integral multiples thereof. The Debenture is exchangeable for an
equal aggregate principal amount of debentures of different authorized
denominations (the "Debentures"), as requested by the Holder(s) surrendering the
same, but not less than US$50,000. No service charge will be made for such
registration, transfer or exchange, except that the Holder shall pay any tax or
other governmental charges payable in connection therewith.

     2. The Company shall be entitled to withhold from all payments of principal
of, and interest on, this Debenture any amounts required to be withheld under
the applicable provisions of the United States income tax laws or other
applicable laws at the time of such payments, and Holder shall execute and
deliver all required documentation in connection therewith.

     3. This Debenture may be transferred or exchanged only in compliance with
the Securities Act of 1933, as amended (the "Act"), and applicable state
securities laws. Prior to due presentment for transfer of this Debenture, the
Company and any agent of the Company may treat the person in whose name this
Debenture is duly registered on the Company's Debenture Register as the owner
hereof for all other purposes, whether or not this Debenture be overdue, and
neither the Company nor any such agent shall be affected or bound by notice to
the contrary.

     4. The Holder of this Debenture is entitled, at its option, at any time
immediately following execution of this Agreement and delivery of the Debenture,
to convert all or any amount over $50,000 of the principal face amount of this
Debenture then outstanding (provided that the principal amount is at least
US$50,000, unless if at the time of such election to convert the aggregate
principal amount of all Debentures registered to the Holder is less than
US$50,000, then the whole amount thereof) into shares of Common Stock. The
conversion price (the "Conversion Price") for each share of Common Stock shall
be equal to the lesser of (a) 85% of the Market Price of the Common Stock on the
Conversion Date; or (b) $2.00. The shares of the Company's Common Stock issued
upon conversion of this Debenture shall hereinafter be referred to as the
"Conversion Shares." If the number of resultant Conversion Shares would as a
matter of law or pursuant to regulatory authority require the Company to seek
shareholder approval of such issuance, the Company shall, as soon as
practicable, take the necessary steps to seek such approval.

     For purposes of this Section 4, the Market Price of the Common Stock shall
be the closing bid price of the Common Stock on the Conversion Date as reported
by Nasdaq, or the closing bid price on the over-the-counter market on such date
or, in the event the Common Stock is listed on a stock exchange, the closing bid
price shall be the closing price on the exchange on such date as reported in the
Wall Street Journal. Conversion shall be effectuated by surrendering the
Debentures to be converted to the Company with the form of conversion notice

such Holder's intention to convert this Debenture or a specified portion (as
above provided) hereof, and accompanied, if required by the Company, by proper
assignment hereof in blank. Interest accrued or accruing from the date of
issuance to the date of conversion shall, at the option of the Holder, be paid
in cash or Common Stock upon conversion at the Conversion Rate. No fraction of
shares or scrip representing fractions of shares will be issued on conversion,
but the number of shares issuable shall be rounded to the nearest whole share.
The date on which notice of conversion is given (the "Conversion Date") shall be
deemed to be the date on which the Holder has delivered this Debenture, with the
conversion notice duly executed, to the Company or the date set forth in such
facsimile delivery of the notice of conversion if the Debenture is received by
the Company within two (2) business days therefrom. Facsimile delivery of the
conversion notice shall be accepted by the Company at (818-247-7614); ATTN:
Albert Gosselin). Certificates representing Common Stock upon conversion will be
delivered within three (3) business days from the date the notice of conversion
with the original Debenture is delivered to the Company.

     5. No provision of the Debenture shall alter or impair the obligation of
the Company, which is direct, absolute and unconditional, to pay the principal
of, and interest on, this Debenture at the time, place, and rate, and in the
form, herein prescribed.

     6. The Company hereby expressly waives demand and presentment for payment,
notice of non-payment, protest, notice of protest, notice of dishonor, notice of
acceleration or intent to accelerate, and diligence in taking any action to
collect amounts called for hereunder and shall be directly and primarily liable
for the payment of all sums owing and to be owing hereto.

     7. The Company agrees to pay all costs and expenses, including reasonable
attorneys' fees, which may be incurred by the Holder in collecting any amount
due under this Debenture.

     8. The following shall constitute an "Event of Default":

          (a)  The Company shall default in the payment of principal
               or interest on this Debenture and such default shall
               remain unremedied for five (5) business days after the
               Company has been notified of the default in writing by
               a Holder; or

          (b)  Any of the representations or warranties made by the

          (i)  Bankruptcy, reorganization, insolvency or liquidation

Then, or at any time thereafter, unless cured, and in each and every such case,
unless such Event of Default shall have been waived in writing by the Holder
(which waiver shall not be deemed to be a waiver of any subsequent default) at
the option of the Holder and in the Holder's sole discretion, the Holder may
consider this Debenture immediately due and payable, without presentment,
demand, protest or (further) notice of any kind (other than notice of
acceleration), all of which are hereby expressly waived, anything herein or in
any note or other instruments contained to the contrary notwithstanding, and the
Holder may immediately, and without expiration of any period of grace, enforce
any and all of the Holder's rights and remedies provided herein and any other
rights or remedies afforded by law.

     9. The Holder of the Debenture, by acceptance hereof, agrees that this
Debenture is being acquired for investment and that such Holder will not offer,
sell or otherwise dispose of this Debenture or the shares of Common Stock
issuable upon conversion thereof except under circumstances which will not
result in a violation of the Act or any applicable state Blue Sky or foreign
laws or similar laws relating to the sale of securities.

     10. Nothing contained in this Debenture shall be construed as conferring
upon the Holder the right to vote or to receive dividends or to consent or
receive notice as a shareholder in respect of any meeting of shareholders or any
rights whatsoever as a shareholder of the Company, unless and to the extent
converted in accordance with the terms hereof.

                                       5
<PAGE>

     11. This Debenture represents a prioritized obligation of the Company.
However, no recourse shall be had for the payment of the principal of, or the
interest on, this Debenture, or for any claim based hereon, or otherwise in
respect hereof, against any incorporator, shareholder, officer or director, as
such, past, present or future, of the Company or any successor corporation,
whether by virtue of any constitution, statute or rule of law, or by the
enforcement of any assessment or penalty or otherwise, all such liability being,
by the acceptance hereof and as part of the consideration for the issue hereof,
expressly waived and released.

     12. If the Company merges or consolidates with another corporation or sells
or transfers all or substantially all of its assets to another person and the
holders of the Common Stock are entitled to receive stock, securities or
property in respect of or in exchange for Common Stock, then as a condition of
such merger, consolidation, sale or transfer, the Company and any such
successor, purchaser or transferee agree that the Debenture may thereafter be
converted on the terms and subject to the conditions set forth above into the
kind and amount of stock, securities or property receivable upon such merger,
consolidation, sale or transfer by a holder of the number of shares of Common
Stock into which this Debenture might have been converted immediately before
such merger, consolidation, sale or transfer, subject to adjustments which shall
be as nearly equivalent as may be practicable. In the event of any proposed
merger, consolidation or sale or transfer of all or substantially all of the
assets of the Company (a "Sale"), the Holder hereof shall have the right to
convert by delivering a Notice of Conversion to the Company within fifteen (15)
days of receipt of notice of such Sale from the Company. In the event the Holder
hereof shall elect not to convert, the Company may prepay all outstanding
principal and accrued interest on this Debenture, less all amounts required by
law to be deducted, upon which tender of payment following such notice, the
right of conversion shall terminate.

     13. Concurrently with the execution and delivery of this Debenture, the
parties hereto will execute and deliver a Registration Rights Agreement in which
the Company will undertake to register the Conversion Shares under the
Securities Act of 1933.

     14. A. Notwithstanding any other provision hereof to the contrary, at any
time prior to the Conversion Date, the Company shall have the right to redeem
all or any portion of the then outstanding principal amount of the Debentures
then held by the Holder for an amount (the "Redemption Payment") equal to the
sum of (a) such outstanding principal of the Debentures plus all accrued but
unpaid interest thereon through the date the Redemption Amount is paid to the
Holder (the "Redemption Payment Date"), multiplied by (b) 1.25. The Company
shall give at least ten (10) business days' written notice of such redemption to
the Holder (the "Notice of Redemption").

          B. Anything in the preceding provisions of this Section 14 to the
contrary notwithstanding, the Redemption Payment shall, unless otherwise agreed
to in writing by the Holder after receiving the Notice of Redemption, be paid to
the Holder at least ten (10) business days from the date of the Notice of
Redemption. Upon the Holder's receipt of the Notice of Redemption, the Holder

                                       6
<PAGE>

shall have the right, exercisable within ten (10) business days of the Holder's
receipt of the Notice of Redemption, to give a Notice of Conversion to the
Company for any or all of the principal amount of the Debenture covered by the
Notice of Redemption (such Notice of Conversion, a "Redemption Notice of
Conversion"). The Redemption Notice of Conversion shall take precedence over the
Notice of Redemption and such Debentures shall be converted in accordance with
the terms hereof. The Redemption Payment for any portion of the Debentures
covered by the Notice of Redemption but not by a Redemption Notice of Conversion
shall be paid no later than on the date ( the "Redemption Payment Date") which
is ten (10) business days after the date the Notice of Redemption is given.

     15. In case any provision of this Debenture is held by a court of competent
jurisdiction to be excessive in scope or otherwise invalid or unenforceable,
such provision shall be adjusted rather than voided, if possible, so that it is
enforceable to the maximum extent possible, and the validity and enforceability
of the remaining provisions of this Debenture will not in any way be affected or
impaired thereby.

     16. This Debenture and the agreements referred to in this Debenture
constitute the full and entire understanding and agreement between the Company
and the Holder with respect to the subject hereof. Neither this Debenture nor
any term hereof may be amended, waived, discharged or terminated other than by a
written instrument signed by the Company and the Holder.

     17. This Debenture shall be governed by and construed in accordance with
the laws of the State of California. Each of the parties consents to the
jurisdiction of the federal courts whose districts encompass any part of the
State of California sitting in connection with any dispute arising under this
Agreement and hereby waives, to the maximum extent permitted by law, any
objection, including any objection based on forum non coveniens, to the bringing
of any such proceeding in such jurisdictions. At Holder's election, any dispute
between the parties may be arbitrated rather than litigated in the courts,
before the arbitration board of the American Arbitrators Association in New York
City and pursuant to its rules. Upon demand made by the Holder to the Company,
the Company agrees to submit to and participate in such arbitration. This
Agreement may be executed in counterparts, and the facsimile transmission of an
executed counterpart to this Agreement shall be effective as an original.

     IN WITNESS WHEREOF, the Company has caused this instrument to be duly
executed by an officer thereunto duly authorized.
