             8% SECURED CONVERTIBLE DEBENTURE DUE FEBRUARY 28, 2002

         FOR VALUE RECEIVED, between BIOGAN INTERNATIONAL, INC., a Delaware
corporation (the "the Company") promises to pay to Carbon Mesa Partners, LLC, a
Nevada limited liability company, the registered holder hereof (the "Holder"),
the principal sum of Thirty Five Thousand Dollars and 00/100 Dollars (US
$35,000) on February 28, 2002 (the "Maturity Date") and to pay interest on the
principal sum outstanding from time to time in arrears (i) prior to the Maturity
Date, quarterly, on the last day of March, June, September and December of each
year, (ii) upon conversion as provided herein or (iii) on the Maturity Date, at
the rate of 8% per annum accruing from March 8, 2000, the date of the issuance
of this Debenture. Accrual of interest shall commence on the first such business

         This Debenture is subject to the following additional provisions:

         1. The Debentures are issuable in denominations of Ten Thousand Dollars
(US$10,000) and integral multiples thereof. The Debentures are exchangeable for
an equal aggregate principal amount of Debentures of different authorized
denominations, as requested by the Holder surrendering the same. No service
charge will be made for such registration or transfer or exchange.

         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 has been issued subject to investment representations
of the original purchaser hereof and may be transferred or exchanged only in
compliance with the Securities Act of 1933, as amended (the "Act"), and other
applicable state and foreign securities laws. In the event of any proposed
transfer of this Debenture, the Company may require, prior to issuance of a new
Debenture in the name of such other person, that it receive reasonable transfer
documentation including legal opinions that the issuance of the Debenture in
such other name does not and will not cause a violation of the Act or any
applicable state or foreign 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 the purpose of receiving payment as
herein provided and for all other purposes, whether or not this Debenture be
overdue, and neither the Company nor any such agent shall be affected by notice
to the contrary.

         4. A. The Holder of this Debenture is entitled, at its option, subject
to the following provisions of this Section 4, to convert all or a portion of
this Debenture into shares of Common Stock of the Company, $0.001 par value per
share ("Common Stock") of the Company at any time until the Maturity Date, at a
conversion price for each share of Common Stock (the "Conversion Rate") equal to
the lower of (x) $0.4166 or (y) the Current Market Price (as defined below)
multiplied by eighty percent (80%); provided that the principal amount being
converted is the lower of (x) at least $10,000 (unless if at the time of such
election to convert the aggregate principal amount of all Debentures registered
to the Holder is less than Ten Thousand Dollars $10,000, then the whole amount
thereof) or (y) the maximum amount which the Holder can then convert pursuant to
the terms of Section 4.E. hereof .

         B. For purposes of this Debenture, the following terms have the
meanings indicated below:

         (i) "Market Price of the Common Stock" means (x) the closing bid price
of the Common Stock for the period indicated in the relevant provision, as
reported by Bloomberg, LP or, if not so reported, as reported on the
over-the-counter market or (y) if the Common Stock is listed on a stock
exchange, the closing price on such exchange, as reported in The Wall Street
Journal.

         (ii) "Current Market Price" means the average Market Price of the
Common Stock for the five (5) trading days ending on the trading day immediately
before the relevant Conversion Date (as defined below).

         C. The Holder of this Debenture is entitled, at its option, to convert
this Debenture at any time which is after the earlier of (x) the thirtieth
(30th) day after the Initial Closing Date or (y) the Effective Date of the
Registrable Securities applicable to the Initial Debentures (as those terms are
defined in the Securities Purchase Agreement); provided, however, that the
Holder may not convert more than thirty three and one-third percent (33 1/3%) of
the original principal amount of the Debentures issued to the Holder (or
Holder's predecessors in interest) during any thirty (30) calendar day period,
nor sell more than that number of shares of Common Stock which equals (i) Thirty
Five Thousand ($35,000), divided by (ii) Conversion Rate.

                                       2

         D. Conversion shall be effectuated by surrendering the Debentures to be
converted to the Company's transfer agent, American Securities Transfer ,
accompanied by or preceded by facsimile or other delivery to the Company of the
form of conversion notice attached hereto as Exhibit A, executed by the Holder
of the Debenture evidencing such Holder's intention to convert this Debenture or
a specified portion hereof, and accompanied, if required by the Company, by
proper assignment hereof in blank. Subject to the provisions of Section 4.E.
hereof, interest accrued or accruing from the date of issuance to the date of
conversion shall, at the option of the Company, be paid in cash or Common Stock
upon conversion at the Conversion Rate applicable to such conversion. No
fractional shares of Common Stock 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 faxes or
otherwise delivers the conversion notice ("Notice of Conversion"), substantially
in the form annexed hereto as Exhibit A, duly executed, to the Company, provided
that the Holder shall deliver to the Company's transfer agent or the Company the
original Debentures being converted within five (5) business days thereafter
(and if not so delivered with such time, the Conversion Date shall be the date
on which the later of the Notice of Conversion and the original Debentures being
converted is received by the Company). Facsimile delivery of the Notice of
Conversion shall be accepted by the Company at facsimile number (450)651-8049;
ATTN: GILLES LaVERDIERE, CHIEF EXECUTIVE OFFICER. Certificates representing
Common Stock upon conversion will be delivered within three (3) business days
from the date later of the Notice of Conversion is delivered to the Company as
contemplated in the first sentence of this paragraph C or the original Debenture
is delivered to the Company's transfer agent or the Company.

         E. Notwithstanding any other provision hereof, of the Warrants or of
any of the other Transaction Agreements (as those terms are defined in the
Securities Purchase Agreement), in no event (except (i) with respect to an
automatic conversion, if any, of a Debenture as provided in the Debentures, (ii)
as specifically provided in this Debenture as an exception to this provision, or
(iii) while there is outstanding a tender offer for any or all of the shares of
the Company's Common Stock) shall the Holder be entitled to convert any
Debenture or shall the Company have the obligation, to convert all or any
portion of this Debenture (and the Company shall not have the right to pay
interest on this Debenture) to the extent that, after such conversion, the sum
of (1) the number of shares of Common Stock beneficially owned by the Holder and
its affiliates (other than shares of Common Stock which may be deemed
beneficially owned through the ownership of the unconverted portion of the
Debentures), and (2) the number of shares of Common Stock issuable upon the
conversion of the Debentures or exercise of the Warrants with respect to which
the determination of this proviso is being made, would result in beneficial
ownership by the Holder and its affiliates of more than 9.99% of the outstanding
shares of Common Stock (after taking into account the shares to be issued to the
Holder upon such conversion or exercise). For purposes of the proviso to the
immediately preceding sentence, beneficial ownership shall be determined in
accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended
(the "1934 Act"), except as otherwise provided in clause (1) of such sentence.
Any issuance by the Company to the Buyer in excess of the limit contained in
this Section 4.E. shall be null and void, AB INITIO, and upon notice of such
invalid issuance, the Company shall correct its books and cause its transfer
agent's books to be corrected forthwith to reflect that the Buyer's ownership of

                                       3
<PAGE>

Common Stock is within the limit set forth herein. Holder shall immediately
deliver any certificates for invalidly issued Common Stock to the Company's
transfer agent. The Company further agrees to (i) immediately reissue
certificates for Common Stock to the extent that a portion of the Common Stock
represented by said certificates have been validly issued and (ii) immediately
reissue all or a portion of those shares which were deemed invalidly issued (at
the Conversion Price set forth in the original conversion notice(s) applicable
to such shares) upon notice from Holder that the reissuance of such shares would
not cause such Holder to have a beneficial ownership interest in excess of
9.99%. Notwithstanding the foregoing, Holder may elect, by providing the Company
written notice at any time prior to the reissuance of shares, to cancel that
portion of a prior conversion applicable to shares of Common Stock surrendered
by it pursuant to this Section 4.E. The Company hereby indemnifies and holds
Holder free and harmless in connection with any and all liabilities, losses,
costs and expenses, including, without limitation, attorneys' fees and costs
arising from or relating to claims made by any third parties with respect to any
and all purported violations by each Buyer under Sections 13(d) and 16 resulting
from a conversion(s) of Debenture, unless such claim arises from such Holder's
default of its obligations hereunder, or representations or warranties contained
herein. The Holder, by its acceptance of this Debenture, further agrees that if
the Holder transfers or assigns any of the Debentures to a party who or which
would not be considered such an affiliate, such assignment shall be made subject
to the transferee's or assignee's specific agreement to be bound by the
provisions of this Section 4(E) as if such transferee or assignee were the
original Holder hereof.

         F. Anything herein to the contrary notwithstanding, in the event the
Company breaches the provisions of Section 4(g) of the Securities Purchase
Agreement, the Conversion Rate shall be amended to be equal to (i) 90% of (ii)
the Conversion Rate determined in accordance with the other provisions of this
Debenture without regard to this Section 4.F., and the Holder may require the
Company to immediately redeem the outstanding portion of this Debenture in
accordance with clause (y) of Section 6 hereof.

         5. Any Debentures not previously converted as of the Maturity Date,
shall be deemed to be automatically converted, without further action of any
kind by the Company or any of its agents, employees or representatives, as of
the Maturity Date at the Conversion Rate applicable on the Maturity Date
("Mandatory Conversion").

         6. The Holder recognizes that the Company may be limited in the number
of shares of Common Stock it may issue by (i) reason of its authorized shares,
or (ii) the applicable rules and regulations of the principal securities market
on which the Common Stock is listed or traded (collectively, the"Cap
Regulations"). Without limiting the other provisions hereof, (i) the Company
will take all steps reasonably necessary to be in a position to issue shares of
Common Stock on conversion of the Debentures without violating the Cap
Regulations and (ii) if, despite taking such steps, the Company still can not
issue such shares of Common Stock without violating the Cap Regulations, the
Holder of this Debenture (to the extent the same can not be converted in
compliance with the Cap Regulations (an "Unconverted Debenture"), shall have the
option, exercisable in the Holder's sole and absolute discretion, to elect any
one of the following remedies:

                                       4
<PAGE>

                  (x) require the Company to issue shares of Common Stock in
         accordance with such Holder's Notice of Conversion relating to the
         Unconverted Debenture at a conversion purchase price equal to the
         average of the closing bid price per share of Common Stock for any five
         (5) consecutive trading days (subject to the equitable adjustments for
         certain events occurring during such period as provided in this
         Debenture) during the sixty (60) trading days immediately preceding the
         date of the Notice of Conversion; or

                  (y) require the Company to redeem each Unconverted Debenture
         for an amount (the "Cap Redemption Amount"), payable in cash, equal to:

                                  V                       x                M
                              ---------
                                 CP

         where:

                  "V" means the outstanding principal plus accrued interest
         through the Cap Redemption Date (as defined below) of an Unconverted
         Debenture;

                  "CP" means the Conversion Rate in effect on the date of
         redemption (the "Cap Redemption Date") specified in the notice from the
         Holder electing this remedy; and

                  "M" means the highest closing ask price during the period
         beginning on the Cap Redemption Date and ending on the date of payment
         of the Cap Redemption Amount.

The holder of an Unconverted Debenture may elect one of the above remedies with
respect to a portion of such Unconverted Debenture and the other remedy with
respect to other portions of the Unconverted Debenture.

         7. Subject to the terms of the Securities Purchase Agreement, dated
March 8, 2000 (the "Securities Purchase Agreement"), between the Company and the
Holder (or the Holder's predecessor in interest), no provision of this Debenture
shall alter or impair the obligation of the Company, which is absolute and
unconditional, to pay the principal of, and interest on, this Debenture at the
time, place, and rate, and in the coin or currency, herein prescribed. This
Debenture and all other Debentures now or hereafter issued of similar terms are
direct obligations of the Company.

                                       5
<PAGE>

         8. 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 by paying the Redemption Amount
contemplated by Section 5(A) hereof, less all amounts required by law to be
deducted, upon which tender of payment following such notice, the right of
conversion shall terminate.

         9. If, for any reason, prior to the Conversion Date or the Redemption
Payment Date, the Company spins off or otherwise divests itself of a part of its
business or operations or disposes all or of a part of its assets in a
transaction (the "Spin Off") in which the Company does not receive compensation
for such business, operations or assets, but causes securities of another entity
(the "Spin Off Securities") to be issued to security holders of the Company,
then the Company shall cause (i) to be reserved Spin Off Securities equal to the
number thereof which would have been issued to the Holder had all of the
Holder's Debentures outstanding on the record date (the "Record Date") for
determining the amount and number of Spin Off Securities to be issued to
security holders of the Company (the "Outstanding Debentures") been converted as
of the close of business on the trading day immediately before the Record Date
(the "Reserved Spin Off Shares"), and (ii) to be issued to the Holder on the
conversion of all or any of the Outstanding Debentures, such amount of the
Reserved Spin Off Shares equal to (x) the Reserved Spin Off Shares multiplied by
(y) a fraction, of which (I) the numerator is the principal amount of the
Outstanding Debentures then being converted, and (II) the denominator is the
principal amount of the Outstanding Debentures.

         10. If, at any time while any portion of this Debenture remains
outstanding, the Company effectuates a stock split or reverse stock split of its
Common Stock or issues a dividend on its Common Stock consisting of shares of
Common Stock, the Base Price shall be equitably adjusted to reflect such action.
By way of illustration, and not in limitation, of the foregoing (i) if the
Company effectuates a 2:1 split of its Common Stock, thereafter, with respect to
any conversion for which the Company issues the shares after the record date of
such split, the Base Price shall be deemed to be one-half of what it had been
calculated to be immediately prior to such split; (ii) if the Company
effectuates a 1:10 reverse split of its Common Stock, thereafter, with respect
to any conversion for which the Company issues the shares after the record date
of such reverse split; and (iii) if the Company declares a stock dividend of one
share of Common Stock for every 10 shares outstanding, thereafter, with respect
to any conversion for which the Company issues the shares after the record date
of such dividend, the Base Price shall be deemed to be the amount of such Base
Price calculated immediately prior to such record date multiplied by a fraction,
of which the numerator is the number of shares (10) for which a dividend share
will be issued and the denominator is such number of shares plus the dividend
share(s) issuable or issued thereon (11).

                                       6
<PAGE>

         11. All payments contemplated hereby to be made "in cash" shall be made
in immediately available good funds in such coin or currency of the United
States of America as at the time of payment is legal tender for payment of
public and private debts. All payments of cash and each delivery of shares of
Common Stock issuable to the Holder as contemplated hereby shall be made to the
Holder at the address last appearing on the Debenture Register of the Company as
designated in writing by the Holder from time to time; except that the Holder
can designate, by notice to the Company, a different delivery address for any
one or more specific payments or deliveries.

         12. 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.

         13. This Debenture and all agreements entered into in connection
herewith shall be governed by and interpreted in accordance with the laws of the
State of California for contracts to be wholly performed in such state and
without giving effect to the principles thereof regarding the conflict of laws.
Any litigation based thereon, or arising out of, under, or in connection with,
this agreement or any course of conduct, course of dealing, statements (whether
oral or written) or actions of the Company or Holder shall be brought and
maintained exclusively in the state or Federal courts of the State of
California, sitting in the City of Los Angeles. The Company hereby expressly and
irrevocably submits to the jurisdiction of the state and federal Courts of the
State of California for the purpose of any such litigation as set forth above
and irrevocably agrees to be bound by any final judgment rendered thereby in
connection with such litigation. The Company further irrevocably consents to the
service of process by registered mail, postage prepaid, or by personal service
within or without the State of California. The Company hereby expressly and
irrevocably waives, to the fullest extent permitted by law, any objection which
it may have or hereafter may have to the laying of venue of any such litigation
brought in any such court referred to above and any claim that any such
litigation has been brought in any inconvenient forum. To the extent that the
Company has or hereafter may acquire any immunity from jurisdiction of any court
or from any legal process (whether through service or notice, attachment prior
to judgment, attachment in aid of execution or otherwise) with respect to itself
or its property, the Company hereby irrevocably waives such immunity in respect
of its obligations under this Agreement and the related agreements entered into
in connection herewith.

         14. In the event that any action is taken by the Company or Holder in
connection with this Note, or any related document or matter, the losing party
in such legal action, in addition to such other damages as he or it may be
required to pay, shall pay reasonable attorneys' fees to the prevailing party.

                                       7

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

                  a.       The Company shall default in the payment of principal
                           or interest on this Debenture and same shall continue
                           for a period of three (3) days; or

                  b.       Any of the representations or warranties made by the
                           Company herein, in the Securities Purchase Agreement,
                           the Registration Rights Agreement or in any
                           certificate or financial or other written statements
                           heretofore or hereafter furnished by the Company in
                           connection with the execution and delivery of this
                           Debenture or the Securities Purchase Agreement shall
                           be false or misleading in any material respect at the
                           time made; or

                  c.       The Company fails to issue shares of Common Stock to
                           the Holder or to cause its Transfer Agent to issue
                           shares of Common Stock upon exercise by the Holder of
                           the conversion rights of the Holder in accordance
                           with the terms of this Debenture, fails to transfer
                           or to cause its Transfer Agent to transfer any
                           certificate for shares of Common Stock issued to the
                           Holder upon conversion of this Debenture and when
                           required by this Debenture or the Registration Rights
                           Agreement, and such transfer is otherwise lawful, or
                           fails to remove any restrictive legend or to cause
                           its Transfer Agent to transfer on any certificate or
                           any shares of Common Stock issued to the Holder upon
                           conversion of this Debenture as and when required by
                           this Debenture, the Agreement or the Registration
                           Rights Agreement and such legend removal is otherwise
                           lawful, and any such failure shall continue uncured
                           for five (5) business days; or

                  d.       The Company shall fail to perform or observe, in any
                           material respect, any other covenant, term,
                           provision, condition, agreement or obligation of this
                           Debenture and such failure shall continue uncured for
                           a period of ten (10) days after written notice from
                           the Holder of such failure; or

                  e.       The Company shall fail to perform or observe, in any
                           material respect, any covenant, term, provision,
                           condition, agreement or obligation of the Company
                           under the Securities Purchase Agreement, the
                           Registration Rights Agreement, the Warrant or the
                           Pledge Agreement (as defined in Section 18 below) and
                           such failure shall continue uncured for a period of
                           ten (10) days after written notice from the Holder of

                           days.

                  l.       An Event of Default has occurred under the terms of
                           any other Debenture (in this series) issued pursuant
                           to the Securities Purchase Agreement.

                                       9
<PAGE>

Then, or at any time thereafter, 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
notice of any kinds, 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 enforce any and all of the Holder's rights and
remedies provided herein, in the Pledge Agreement, the Letter of Credit (as
defined in Section 18 below) or any other rights or remedies afforded by law.

         16. 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.

         17. In the event for any reason, any payment by or act of the Company
or the Holder shall result in payment of interest which would exceed the limit
authorized by or be in violation of the law of the jurisdiction applicable to
this Debenture, the IPSO FACTO the obligation of the Company to pay interest or
perform such act or requirement shall be reduced to the limit authorized under
such law, so that in no event shall the Company be obligated to pay any such
interest, perform any such act or be bound by any requirement which would result
in the payment of interest in excess of the limit so authorized. In the event
any payment by or act of the Company shall result in the extraction of a rate of
interest in excess of a sum which is lawfully collectible as interest, then such
amount (to the extent of such excess not returned to the Company) shall, without
further agreement or notice between or by the Company or the Holder, be deemed
applied to the payment of principal, if any, hereunder immediately upon receipt
of such excess funds by the Holder, with the same force and effect as though the
Company had specifically designated such sums to be so applied to principal and
the Holder had agreed to accept such sums as an interest-free prepayment of this
Debenture. If any part of such excess remains after the principal has been paid
in full, whether by the provisions of the preceding sentences of this Section 17
or otherwise, such excess shall be deemed to be an interest-free loan from the
Company to the Holder, which loan shall be payable immediately upon demand by
the Company. The provisions of this Section 17 shall control every other
provision of this Debenture.

         18. The obligations of the Company contained herein and in the Security
Purchase Agreement are secured by (i) that certain Stock Pledge Agreement (the
"Pledge Agreement"), dated the date hereof, by and among the Company, the Holder
and (the holders of other Debentures delivered pursuant to the Securities
Purchase Agreement, if any), whereby the Company has delivered 28,800,000 shares
of Common Stock to the Escrow Holder (as that term is defined in the Pledge
Agreement), in the form attached to the Securities Purchase Agreement as Annex
VII, and (ii) that certain Standby Letter of Credit issued by the Bank of India
(New York City office), in the form attached to the Securities Purchase
Agreement as Annex VIII.

                                       10
<PAGE>

         19. Time is of the essence as to the performance of each and every
obligation of the Company and Holder pursuant to this Debenture.

         20. A. On the condition that the Company is not in default under this
Debenture (or no event has occurred that would ripen into a default with the
passage of time) the Company may, at its option, repay, in whole or in part, the
then outstanding principal and interest balance of this Debenture on the date of
the Redemption Notice (after deducting the principal and interest subject to
outstanding Conversion Notices) at the Redemption Price (as defined below). This
Debenture is redeemable, in whole or in part, by the Company by providing
written notice (the "REDEMPTION NOTICE") to the Holder via facsimile at its
address set froth herein (the Business Day between the hours of 6:30 a.m. and
3:00 p.m. Pacific Time the Redemption Notice is received by the Holder via
facsimile is defined to be the "REDEMPTION NOTICE DATE"). Within ten Trading
Days after the Redemption Notice Date the Company shall make payment of the
Redemption Price (as defined below) in immediately available funds to the Holder
(such date of payment referred to as the "REDEMPTION DATE"). Partial redemptions
shall be in an aggregate principal amount of at least $100,000. The Company
shall redeem, pro-rata amongst the Holder and the holders of other Debentures in
the series (if any) based on then outstanding balance due under the Debenture
and the other Debentures in the series.

         B. In the event the Company serves a Redemption Notice, the Redemption
Price shall be equal to 125% of the outstanding principal and interest balance
of the Debenture.

         C. The Notice of Redemption shall set forth (i) the Redemption Date and
the place fixed for redemption, (ii) the Redemption Price,(iii) a statement of
or reference to the conversion right set forth herein, and (iv) confirmation
that the Company has the full Redemption Price reserved as set forth in F.
below. The notice shall specify the principal and interest balance hereof to be
redeemed. Within five Trading Days of the Redemption Notice Date, the Company
shall wire transfer the appropriate amount of funds to the Holder. If the
Company fails to comply with the redemption provisions set forth herein by the
sixth Trading Day after the Redemption Notice Date (or in the case of a public
offering as contemplated in F. below, by the sixth Trading Day after the
Redemption Notice Date) relating to the Redemption Notice, the redemption will
be declared null and void and the Company shall not be permitted to serve
another Redemption Notice. For the first five Trading Days after the Redemption
Notice Date, the Holder will retain its conversion rights with respect to a
maximum of fifty percent (50%) of the principal and interest amount subject to
the redemption. If the Holder elects to so convert the said principal and
interest after the receipt of the Redemption Notice, the Company must receive
notice of such election within two (2) business days from the time the
Redemption Notice was received by the Holder. In the event the Company has not
complied with the redemption provisions set forth herein the Company must comply
with the delivery requirements of any then outstanding Conversion Notice as set
forth herein. If the entire balance of interest and principal of this Debenture
is redeemed hereunder, the Holder shall deliver to the Company the original of
this Debenture within three (3) Business Days after it has received good funds
for the Redemption Price.

         D. Intentionally deleted.

         E. The Redemption Price shall be adjusted proportionally upon any
adjustment of the Conversion Price as provided herein and in the event of any
stock dividend, stock split, combination of shares or similar event.

         F. The Company shall not be entitled to send any Redemption Notice and
begin the redemption procedure hereunder unless it has:

                  (a)      the full amount of the Redemption Price in cash,
                           available in a demand or other immediately available
                           account in a bank or similar financial institution,
                           specifically allotted for such redemption;

                  (b)      immediately available credit facilities, in the full
                           amount of the Redemption Price with a bank or similar
                           financial institution specifically allotted for such
                           redemption; or

                  (c)      a combination of the items set forth in (i) and (ii)
                           above, aggregating the full amount of the Redemption
                           Price.

Notwithstanding the foregoing, in the event the redemption is expected to be
made contemporaneously with the closing of a public offering of the Company's
securities for an amount in excess of the Redemption Price, the Company shall
not be required to have the full amount of the Redemption Price available to it
as set forth above.

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

                          REGISTRATION RIGHTS AGREEMENT

         THIS REGISTRATION RIGHTS AGREEMENT, dated as of March 8, 2000 (this
"Agreement"), is made by and between BIOGAN INTERNATIONAL, INC., a Delaware

                              W I T N E S S E T H:

         WHEREAS, upon the terms and subject to the conditions of the Securities
Purchase Agreement, dated as of March 8, 2000, between the Initial Investors and
the Company (the "Securities Purchase Agreement"; capitalized terms not
otherwise defined herein shall have the meanings ascribed to them in the
Securities Purchase Agreement), the Company has agreed to issue and sell to the
Initial Investors an 8% Secured Convertible Debenture, in the principal amount
of $2,035,000 (which may be issued to each individual Buyer in series) (the
"Debentures") which term, as used herein shall have the meaning ascribed to it
in the Securities Purchase Agreement); and

         WHEREAS, the Company has agreed to issue the Warrants to the Initial
Investors in connection with the issuance of the Debentures; and

         WHEREAS, the Debentures are convertible into shares of Common Stock
(the "Conversion Shares") upon the terms and subject to the conditions set forth
therein; and

         WHEREAS, the Warrants to be issued to the Initial Investors may be
exercised for the purchase of shares of Common Stock (the "Warrant Shares") upon
the terms and conditions of the Warrants; and

         WHEREAS, to induce the Initial Investors to execute and deliver the
Securities Purchase Agreement, the Company has agreed to provide certain
registration rights under the Securities Act of 1933, as amended, and the rules
and regulations thereunder, or any similar successor statute (collectively, the
"Securities Act"), with respect to the Conversion Shares and the Warrant Shares;

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants contained herein and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the Company and the
Initial Investor hereby agree as follows:

                                       1
<PAGE>

         1. DEFINITIONS. As used in this Agreement, the following terms shall
have the following meanings:

         (a) "Investors" means the Initial Investors and any permitted
transferee or assignee who agrees to become bound by the provisions of this
Agreement in accordance with Section 9 hereof.

         (b) "Potential Material Event" means any of the following: (i) the
possession by the Company of material information not ripe for disclosure in a
registration statement, which shall be evidenced by determinations in good faith
by the Board of Directors of the Company that disclosure of such information in
the registration statement would be detrimental to the business and affairs of
the Company; or (ii) any material engagement or activity by the Company which
would, in the good faith determination of the Board of Directors of the Company,
be adversely affected by disclosure in a registration statement at such time,
which determination shall be accompanied by a good faith determination by the
Board of Directors of the Company that the registration statement would be
materially misleading absent the inclusion of such information.

         (c) "Register," "Registered," and "Registration" refer to a
registration effected by preparing and filing a Registration Statement or
Statements in compliance with the Securities Act and pursuant to Rule 415 under
the Securities Act or any successor rule providing for offering securities on a
continuous basis ("Rule 415"), and the declaration or ordering of effectiveness
of such Registration Statement by the United States Securities and Exchange
Commission (the "SEC").

         (d) "Registrable Securities" means the Conversion Shares and the
Warrant Shares.

         (e) "Registration Statement" means a registration statement of the
Company under the Securities Act.

         2. REGISTRATION.

         (a) MANDATORY REGISTRATION. The Company shall prepare and file with the
SEC, as soon as possible after the Closing Date, but no later than thirty (30)
days following the Closing Date, a Registration Statement on Form SB-2,
registering for resale by the Investors all of the Registrable Securities, but
in no event less than two hundred percent (200%) of the aggregate number of
shares into (i) which the Debentures would be convertible at the time of filing
of the Registration Statement (assuming for such purposes that the entire
principal and interest balance of all Debentures had been eligible to be
converted, and had been converted, into Conversion Shares in accordance with
their terms, whether or not such eligibility or conversion had in fact occurred
as of such date), and (ii) which would be issued upon exercise of all of the
Warrants at the time of filing of the Registration Statement (assuming for such
purposes that all such Warrants had been eligible to be exercised and had been
exercised in accordance with their terms, whether or not such eligibility or

                                       2
<PAGE>

exercise had in fact occurred as of such date). The Registration Statement shall
also state that, in accordance with Rule 416 and 457 under the Securities Act,
it also covers such indeterminate number of additional shares of Common Stock as
may become issuable upon conversion of the Debentures and the exercise of the
Warrants (and the Existing Warrants) to prevent dilution resulting from stock
splits, or stock dividends. The Company will use its best efforts to cause the
Registration Statement to be declared effective no later than one hundred twenty
days (120) days after the Closing Date. If at any time the number of shares of
Common Stock into which the Debentures may be converted and which would be
issued upon exercise of the Warrants equals more than seventy five percent (75%)
of the aggregate number of shares of Common Stock then registered, the Company
shall, within ten (10) business days after receipt of a written notice from any
Investor, either (i) further amend the Registration Statement filed by the
Company pursuant to the preceding sentence, if such Registration Statement has
not been declared effective by the SEC at that time, to register 200% of the
aggregate of all shares of Common Stock into which the Debentures may then or in
the future be converted and which would be issued currently or in the future
upon exercise of the Warrants, or (ii) if such Registration Statement has been
declared effective by the SEC at that time, file with the SEC an additional
Registration Statement on Form SB-2, as may be appropriate, to register (A) 200%
of the aggregate shares of Common Stock into which the Debentures may then or in
the future be converted and which would be issued currently or in the future
upon exercise of the unexercised Warrants, less (B) the aggregate number of
shares of Common Stock already registered which have not been issued upon
conversions of the Debentures or the exercise of Warrants. THE REGISTRATION
STATEMENT SHALL NOT INCLUDE ANY SHARES OTHER THAN THE REGISTRABLE SECURITIES,
AND CERTAIN OTHER SHARES THAT THE COMPANY IS OBLIGATED TO REGISTER AS SET FORTH
IN SCHEDULE 5(B), WITHOUT THE CONSENT OF THE INVESTORS.

         (b) PAYMENTS BY THE COMPANY.

                  (i) If the Registration Statement covering the Registrable
Securities is not filed with the SEC on or before thirty (30) days after the
Closing Date (the "Required Filing Date"), then the Company shall pay each
Investor a late filing penalty (collectively "Late Filing Penalties"), (i) on
the first day after the Required Filing Date, an amount equal to two percent
(2%) of the original purchase price paid pursuant to the Securities Purchase
Agreement (the "Purchase Price") for the Debentures, and (ii) on each subsequent
monthly anniversary of the Required Filing Date, if the Registration Statement
has not been filed in proper form on or before such date, an amount equal to
three percent (3%) of the Purchase Price for the Debentures.

                  (ii) If the Registration Statement covering the Registrable
Securities is not effective within the earlier of (a) five (5) days after notice
by the SEC that it may be declared effective (including the issuance by the SEC
of a "no review letter"), or (b) one hundred twenty (120) days following the
Closing Date (the "Required Effective Date"), then the Company shall pay each
Investor a late effective date penalty (collectively "Late Effective Date
Penalties")(sometimes Late Filing Penalties and Late Effective Penalties are
collectively referred to as "Late Penalties"), (i) on the first day after the
Required Effective Date, an amount equal to two percent (2%) of the Purchase
Price for the Debentures and (ii) on each subsequent monthly anniversary of the
Required Effective Date, if the Registration Statement has not been declared
effective on or before such date, an amount equal to three percent (3%) of the
Purchase Price for the Debentures.

                                       3
<PAGE>

                  (iii) By way of illustration and not in limitation of the
foregoing, assuming a Closing Date of February 3, 2000 (X) if the Registration
Statement is timely filed but is not declared effective until July 15, 2000
(assuming for the purpose of this example that the SEC has not previously
provided notice that it may be declared effective), the aggregate Late Effective
Date Penalty will equal 5% percent of the Purchase Price (2% on June 4, the
120th day after the Closing Date, plus 3% on July 2) or (Y) if the Registration
is filed on April 9 and is not declared effective until June 15, 2000 (assuming
for the purpose of this example that the SEC has not previously provided notice
that it may be declared effective), the aggregate Late Filing Penalty will equal
8% of the Purchase Price (2% on March 5, the 30th day after the Closing Date,
plus 3% on April 4 and May 4) and the aggregate Late Effective Date Penalty will
equal 2% percent of the Purchase Price (2% on June 4, the 120th day after the
Closing Date).

                  (iv) Additionally, if the Registration Statement is not filed
within sixty (60) days from the Closing Date, each Investor may, at its option,
require the Company to redeem the Debentures in full, within three (3) days, in
cash, in accordance with Section 6 of the Debenture.

                  (v) Late Penalties will be payable to the Investor by the
Company in cash or other immediately available funds on the date such Late
Penalty is incurred.

                  (vi) The parties acknowledge that the damages which may be
incurred by the Investors if the Registration Statement is not filed by the
Required Filing Date or if the Registration Statement has not been declared
effective by the Required Registration Date may be difficult to ascertain. The
parties agree that the Late Penalties represent a reasonable estimate on the
part of the parties, as of the date of this Agreement, of the amount of such
damages. The payment of the Late Penalties to the Investors shall not limit the
Investors' other rights and remedies hereunder or under any other document
entered into in connection herewith.

                  (vii) Notwithstanding the foregoing, the amounts payable by
the Company pursuant to this provision shall not be payable to the extent any
delay in the effectiveness of the Registration Statement occurs because of an
act of, or a failure to act or to act timely by the Investors or their counsel
if the Company timely forwards to counsel any required documents or in the event
all of the Registrable Securities may be sold pursuant to Rule 144 or another
available exemption under the Act.

         3. OBLIGATIONS OF THE COMPANY. In connection with the registration of
the Registrable Securities, the Company shall do each of the following.

         (a) Prepare promptly, and file with the SEC by the Required Filing
Date, the Registration Statement with respect to not less than the number of
Registrable Securities provided in Section 2(a) above, and thereafter use its
reasonable best efforts to cause each Registration Statement relating to
Registrable Securities to become effective by the Required Effective Date and
keep the Registration Statement effective at all times until the earliest (the
"Registration Period") of (i) the date that is two (2) years after the Closing
Date, (ii) the date when the Investors may sell all Registrable Securities under
Rule 144 or (iii) the date the Investors no longer own any of the Registrable
Securities, which Registration Statement (including any amendments or
supplements thereto and prospectuses contained therein) shall not contain any
untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary to make the statements therein, in light of the
circumstances in which they were made, not misleading;

                                       4
<PAGE>

         (b) Prepare and file with the SEC such amendments (including
post-effective amendments) and supplements to the Registration Statement and the
prospectus used in connection with the Registration Statement as may be
necessary to keep the Registration effective at all times during the
Registration Period, and, during the Registration Period, comply with the
provisions of the Securities Act with respect to the disposition of all
Registrable Securities of the Company covered by the Registration Statement
until such time as all of such Registrable Securities have been disposed of in
accordance with the intended methods of disposition by the seller or sellers
thereof as set forth in the Registration Statement;

         (c) The Company shall permit a single firm or counsel designated by the
Investors to review the Registration Statement and all amendments and
supplements thereto a reasonable period of time (but not less than three (3)
business days) prior to their filing with the SEC, and not file any document in
a form to which such counsel reasonably objects.

         (d) Notify the Investors, their counsel and managing underwriters, if
any, immediately (and, in the case of (i)(A) below, not less than five (5) days
prior to such filing) and (if requested by any such Person) confirm such notice
in writing no later than one (1) Business Day following the day (i)(A) when a
Prospectus or any Prospectus supplement or post-effective amendment to the
Registration Statement is proposed to be filed; (B) whenever the Commission
notifies the Company whether there will be a "review" of such Registration
Statement; (C) whenever the Company receives (or representatives of the Company
receive on its behalf) any oral or written comments from the Commission in
respect of a Registration Statement (copies or, in the case of oral comments,
summaries of such comments shall be promptly furnished by the Company to the
Investors); and (D) with respect to the Registration Statement or any
post-effective amendment, when the same has become effective; (ii) of any
request by the Commission or any other Federal or state governmental authority
for amendments or supplements to the Registration Statement or Prospectus or for
additional information; (iii) of the issuance by the Commission of any stop
order suspending the effectiveness of the Registration Statement covering any or
all of the Registrable Securities or the initiation of any Proceedings for that
purpose; (iv) if at any time any of the representations or warranties of the
Company contained in any agreement (including any underwriting agreement)
contemplated hereby ceases to be true and correct in all material respects; (v)
of the receipt by the Company of any notification with respect to the suspension
of the qualification or exemption from qualification of any of the Registrable
Securities for sale in any jurisdiction, or the initiation or threatening of any
Proceeding for such purpose; and (vi) of the occurrence of any event that to the
best knowledge of the Company makes any statement made in the Registration
Statement or Prospectus or any document incorporated or deemed to be
incorporated therein by reference untrue in any material respect or that
requires any revisions to the Registration Statement, Prospectus or other
documents so that, in the case of the Registration Statement or the Prospectus,
as the case may be, it will not contain any untrue statement of a material fact
or omit to state any material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading. In addition, the Company shall furnish the Investors with
copies of all intended written responses to the comments contemplated in clause
(C) of this Section 3(d) not later than one (1) Business Day in advance of the
filing of such responses with the Commission so that the Investors shall have
the opportunity to comment thereon.

                                       5
<PAGE>

         (e) Furnish to each Investor whose Registrable Securities are included
in the Registration Statement and its legal counsel identified to the Company,
(i) promptly after the same is prepared and publicly distributed, filed with the
SEC, or received by the Company, one (1) copy of the Registration Statement,
each preliminary prospectus and prospectus, and each amendment or supplement
thereto, and (ii) such number of copies of a prospectus, and all amendments and
supplements thereto and such other documents, as such Investor may reasonably
request in order to facilitate the disposition of the Registrable Securities
owned by such Investor;

         (f) As promptly as practicable after becoming aware of such event,
notify each Investor of the happening of any event of which the Company has
knowledge, as a result of which the prospectus included in the Registration
Statement, as then in effect, includes an untrue statement of a material fact or
omits to state a material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading, and use its best efforts promptly to prepare a supplement
or amendment to the Registration Statement or other appropriate filing with the
SEC to correct such untrue statement or omission, and deliver a number of copies
of such supplement or amendment to each Investor as such Investor may reasonably
request;

         (g) As promptly as practicable after becoming aware of such event,
notify each Investor who holds Registrable Securities being sold (or, in the
event of an underwritten offering, the managing underwriters) of the issuance by
the SEC of a Notice of Effectiveness or any notice of effectiveness or any stop
order or other suspension of the effectiveness of the Registration Statement at
the earliest possible time;

         (h) Notwithstanding the foregoing, if at any time or from time to time
after the date of effectiveness of the Registration Statement, the Company
notifies the Investors in writing of the existence of a Potential Material
Event, the Investors shall not offer or sell any Registrable Securities, or
engage in any other transaction involving or relating to the Registrable
Securities, from the time of the giving of notice with respect to a Potential
Material Event until such Investor receives written notice from the Company that
such Potential Material Event either has been disclosed to the public or no
longer constitutes a Potential Material Event; PROVIDED, HOWEVER, that the
Company may not so suspend the right to such holders of Registrable Securities
for more than two twenty (20) day periods in the aggregate during any 12-month
period ("Suspension Period") with at least a ten (10) business day interval
between such periods, during the periods the Registration Statement is required
to be in effect;

                                       6
<PAGE>

         (i) Use its reasonable efforts to secure or maintain, as applicable,
NASDAQ/OTC Bulletin Board authorization and quotation for such Registrable
Securities and, without limiting the generality of the foregoing, to arrange for
at least two market makers to register with the National Association of
Securities Dealers, Inc. ("NASD") as such with respect to such Registrable
Securities;

         (j) Provide a transfer agent and registrar, which may be a single
entity, for the Registrable Securities not later than the effective date of the
Registration Statement;

         (k) Cooperate with the Investors who hold Registrable Securities (or,
subject to receipt by the Company of appropriate notice and documentation, as
may be required by the Securities Purchase Agreement, the Certificate of
Designations, the Warrants or this Agreement, securities convertible into
Registrable Securities) being offered to facilitate the timely preparation and
delivery of certificates for the Registrable Securities to be offered pursuant
to the Registration Statement and enable such certificates for the Registrable
Securities to be in such denominations or amounts as the case may be, as the
Investors may reasonably request, and, within five (5) business days after a
Registration Statement which includes Registrable Securities is ordered
effective by the SEC, the Company shall deliver, and shall cause legal counsel
selected by the Company to deliver, to the transfer agent for the Registrable
Securities (with copies to the Investors whose Registrable Securities or
securities convertible into Registrable Securities are included in such
Registration Statement) an appropriate instruction and opinion of such counsel;
provided, however, that nothing in this subparagraph (j) shall be deemed to
waive any of the provisions regarding the conditions or method of conversion of
The Debentures or exercise of Warrants into Registrable Securities; and

         (l) Take all other reasonable actions necessary to expedite and
facilitate disposition by the Investor of the Registrable Securities pursuant to
the Registration Statement.

         4. OBLIGATIONS OF THE INVESTORS. In connection with the registration of
the Registrable Securities, each Investor shall have the following obligations:

         (a) As a condition precedent to the obligations of the Company to
complete the registration pursuant to this Agreement with respect to the
Registrable Securities of a particular Investor, such Investor shall furnish to
the Company such information regarding itself, the Registrable Securities held
by it, and the intended method of disposition of the Registrable Securities held
by it, as shall be reasonably required to effect the registration of such
Registrable Securities and shall execute such documents in connection with such
registration as the Company may reasonably request. At least five (5) days prior
to the first anticipated filing date of the Registration Statement, the Company
shall notify each Investor of the information the Company requires from each
such Investor (the "Requested Information") if such Investor elects to have any
of such Investor's Registrable Securities included in the Registration
Statement. If at least two (2) business days prior to the filing date the
Company has not received the Requested Information from an Investor (a
"Non-Responsive Investor"), then the Company may file the Registration Statement
without including Registrable Securities of such Non-Responsive Investor;

                                       7
<PAGE>

         (b) To cooperate with the Company as reasonably requested by the
Company in connection with the preparation and filing of the Registration
Statement hereunder, unless such Investor has notified the Company in writing of
such Investor's election to exclude all of such Investor's Registrable
Securities from the Registration Statement; and

         (c) Upon receipt of any notice from the Company of the happening of any
event of the kind described in Section 3(e) or 3(f), above, such Investor shall
immediately discontinue disposition of Registrable Securities pursuant to the
Registration Statement covering such Registrable Securities until such
Investor's receipt of the copies of the supplemented or amended prospectus
contemplated by Section 3(e) or 3(f) and, if so directed by the Company, such
Investor shall deliver to the Company (at the expense of the Company) or destroy
(and deliver to the Company a certificate of destruction) all copies in such
Investor's possession, of the prospectus covering such Registrable Securities
current at the time of receipt of such notice.

         5. EXPENSES OF REGISTRATION. (a) All reasonable expenses (other than
underwriting discounts and commissions of each Investor and legal fees of
counsel to each Investor) incurred in connection with registrations, filings or
qualifications pursuant to Section 3, including, without limitation, all
registration, listing, and qualifications fees, printers and accounting fees,
the fees and disbursements of counsel for the Company, and a fee for a single
counsel for the Investors not exceeding $3,500, shall be borne by the Company.

         (b) Except as and to the extent specifically set forth in Schedule 5(b)
attached hereto, neither the Company nor any of its subsidiaries has, as of the
date hereof, nor shall the Company nor any of its subsidiaries, on or after the
date of this Agreement, enter into any agreement with respect to its securities
that is inconsistent with the rights granted to the Investors herein or
otherwise conflicts with the provisions hereof. Except as and to the extent
specifically set forth in Schedule 5(b) attached hereto, neither the Company nor
any of its subsidiaries has previously entered into any agreement granting any
registration rights with respect to any of its securities to any person or
entity. Without limiting the generality of the foregoing, without the written
consent of the Investors of a majority of the then outstanding Registrable
Securities, the Company shall not grant to any person the right to request the
Company to register any securities of the Company under the Securities Act
unless the rights so granted are subject in all respects to the prior rights in
full of the Investors set forth herein, and are not otherwise in conflict or
inconsistent with the provisions of this Agreement.

         6. INDEMNIFICATION. In the event any Registrable Securities are
included in a Registration Statement under this Agreement:

                                       8
<PAGE>

         (a) To the extent permitted by law, the Company will indemnify and hold
harmless each Investor who holds such Registrable Securities, the directors, if
any, of such Investor, the officers, if any, of such Investor, each person, if
any, who controls any Investor within the meaning of the Securities Act or the
Securities Exchange Act of 1934, as amended (the "Exchange Act") (each, an
"Indemnified Person" or "Indemnified Party"), against any losses, claims,
damages, liabilities or expenses (joint or several) incurred (collectively,
"Claims") to which any of them may become subject under the Securities Act, the
Exchange Act or otherwise, insofar as such Claims (or actions or proceedings,
whether commenced or threatened, in respect thereof) arise out of or are based
upon any of the following statements, omissions or violations in the
Registration Statement, or any post-effective amendment thereof, or any
prospectus included therein: (i) any untrue statement or alleged untrue
statement of a material fact contained in the Registration Statement or any
post-effective amendment thereof or the omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, (ii) any untrue statement or alleged untrue
statement of a material fact contained in the final prospectus (as amended or
supplemented, if the Company files any amendment thereof or supplement thereto
with the SEC) or the omission or alleged omission to state therein any material
fact necessary to make the statements made therein, in light of the
circumstances under which the statements therein were made, not misleading or
(iii) any violation or alleged violation by the Company of the Securities Act,
the Exchange Act, any state securities law or any rule or regulation under the
Securities Act, the Exchange Act or any state securities law (the matters in the
foregoing clauses (i) through (iii) being, collectively, "Violations"). Subject
to clause (b) of this Section 6, the Company shall reimburse the Investors,
promptly as such expenses are incurred and are due and payable, for any legal
fees or other reasonable expenses incurred by them in connection with
investigating or defending any such Claim. Notwithstanding anything to the
contrary contained herein, the indemnification agreement contained in this
Section 6(a) shall not (I) apply to a Claim arising out of or based upon a
Violation which occurs in reliance upon and in conformity with information
furnished in writing to the Company by or on behalf of any Indemnified Person
expressly for use in connection with the preparation of the Registration
Statement or any such amendment thereof or supplement thereto, if such
prospectus was timely made available by the Company pursuant to Section 3(c)
hereof; (II) be available to the extent such Claim is based on a failure of the
Investor to deliver or cause to be delivered the prospectus made available by
the Company; or (III) apply to amounts paid in settlement of any Claim if such
settlement is effected without the prior written consent of the Company, which
consent shall not be unreasonably withheld. Each Investor will indemnify the
Company and its officers, directors and agents against any claims arising out of
or based upon a Violation which occurs in reliance upon and in conformity with
information furnished in writing to the Company, by or on behalf of such
Investor, expressly for use in connection with the preparation of the
Registration Statement, subject to such limitations and conditions as are
applicable to the Indemnification provided by the Company to this Section 6.
Such indemnity shall remain in full force and effect regardless of any
investigation made by or on behalf of the Indemnified Person and shall survive
the transfer of the Registrable Securities by the Investors pursuant to Section
9.

                                       9
<PAGE>

         (b) Promptly after receipt by an Indemnified Person or Indemnified
Party under this Section 6 of notice of the commencement of any action
(including any governmental action), such Indemnified Person or Indemnified
Party shall, if a Claim in respect thereof is to be made against any
indemnifying party under this Section 6, deliver to the indemnifying party a
written notice of the commencement thereof and the indemnifying party shall have
the right to participate in, and, to the extent the indemnifying party so
desires, jointly with any other indemnifying party similarly noticed, to assume
control of the defense thereof with counsel mutually satisfactory to the
indemnifying party and the Indemnified Person or the Indemnified Party, as the
case may be. In case any such action is brought against any Indemnified Person
or Indemnified Party, and it notifies the indemnifying party of the commencement
thereof, the indemnifying party will be entitled to participate in, and, to the
extent that it may wish, jointly with any other indemnifying party similarly
notified, assume the defense thereof, subject to the provisions herein stated
and after notice from the indemnifying party to such Indemnified Person or
Indemnified Party of its election so to assume the defense thereof, the
indemnifying party will not be liable to such Indemnified Person or Indemnified
Party under this Section 6 for any reasonable legal or other reasonable
out-of-pocket expenses subsequently incurred by such Indemnified Person or
Indemnified Party in connection with the defense thereof other than reasonable
costs of investigation, unless the indemnifying party shall not pursue the
action of its final conclusion. The Indemnified Person or Indemnified Party
shall have the right to employ separate counsel in any such action and to
participate in the defense thereof, but the fees and reasonable out-of-pocket
expenses of such counsel shall not be at the expense of the indemnifying party
if the indemnifying party has assumed the defense of the action with counsel
reasonably satisfactory to the Indemnified Person or Indemnified Party. The
failure to deliver written notice to the indemnifying party within a reasonable
time of the commencement of any such action shall not relieve such indemnifying
party of any liability to the Indemnified Person or Indemnified Party under this
Section 6, except to the extent that the indemnifying party is prejudiced in its
ability to defend such action. The indemnification required by this Section 6
shall be made by periodic payments of the amount thereof during the course of
the investigation or defense, as such expense, loss, damage or liability is
incurred and is due and payable.

         7. CONTRIBUTION. To the extent any indemnification by an indemnifying
party is prohibited or limited by law, the indemnifying party agrees to make the
maximum contribution with respect to any amounts for which it would otherwise be
liable under Section 6 to the fullest extent permitted by law; PROVIDED,
HOWEVER, that (a) no contribution shall be made under circumstances where the
maker would not have been liable for indemnification under the fault standards
set forth in Section 6; (b) no seller of Registrable Securities guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any seller of Registrable
Securities who was not guilty of such fraudulent misrepresentation; and (c)
contribution by any seller of Registrable Securities shall be limited in amount
to the net amount of proceeds received by such seller from the sale of such
Registrable Securities.

                                       10
<PAGE>

         8. REPORTS UNDER EXCHANGE ACT. With a view to making available to the
Investors the benefits of Rule 144 promulgated under the Securities Act or any
other similar rule or regulation of the SEC that may at any time permit the
Investors to sell securities of the Company to the public without registration
("Rule 144"), the Company agrees to:

         (a) make and keep public information available, as those terms are
understood and defined in Rule 144;

         (b) use its best efforts to file with the SEC in a timely manner all
reports and other documents required of the Company under the Securities Act and
the Exchange Act; and

         (c) furnish to each Investor so long as such Investor owns Registrable
Securities, promptly upon request, (i) a written statement by the Company that
it has complied with the reporting requirements of Rule 144, the Securities Act
and the Exchange Act, (ii) a copy of the most recent annual or quarterly report
of the Company and such other reports and documents so filed by the Company and
(iii) such other information as may be reasonably requested to permit the
Investors to sell such securities pursuant to Rule 144 without registration.

         9. ASSIGNMENT OF THE REGISTRATION RIGHTS. The rights to have the
Company register Registrable Securities pursuant to this Agreement shall be
automatically assigned by an Investor to any transferee of the Registrable
Securities (or all or any portion of any Debentures of the Company which is
convertible into such securities) permitted or allowable by the terms of the
Securities Purchase Agreement only if: (a) such Investor agrees in writing with
the transferee or assignee to assign such rights, and a copy of such agreement
is furnished to the Company within a reasonable time after such assignment, (b)
the Company is, within a reasonable time after such transfer or assignment,
furnished with written notice of (i) the name and address of such transferee or
assignee and (ii) the securities with respect to which such registration rights
are being transferred or assigned, (c) immediately following such transfer or
assignment the further disposition of such securities by the transferee or
assignee is restricted under the Securities Act and applicable state securities
laws, and (d) at or before the time the Company received the written notice
contemplated by clause (b) of this sentence the transferee or assignee agrees in
writing with or in favor of the Company to be bound by all of the provisions
contained herein, a copy of which shall be provided to the Company. The copies
referred to in clauses (a) and (d) of the immediately preceding sentence may be
redacted to delete certain financial and other details of the transaction
between the Investor and its transferee if the same is included in the document
to be provided to the Company. In the event of any delay in filing or
effectiveness of the Registration Statement as a result of such assignment, the
Company shall not be liable for any damages arising from such delay, or the
payments set forth in Section 2(c) hereof.

         10. AMENDMENT OF REGISTRATION RIGHTS. Any provision of each such
Agreement may be amended and the observance thereof may be waived (either
generally or in a particular instance and either retroactively or
prospectively), only with the written consent of the Company and Investors who
hold collectively eighty (80%) percent of the Preferred Shares. Any amendment or
waiver effected in accordance with this Section 10 shall be binding upon each
Investor and the Company.

                                       11

         11. MISCELLANEOUS.

         (a) A person or entity is deemed to be a holder of Registrable
Securities whenever such person or entity owns of record such Registrable
Securities. If the Company receives conflicting instructions, notices or
elections from two or more persons or entities with respect to the same
Registrable Securities, the Company shall act upon the basis of instructions,
notice or election received from the registered owner of such Registrable
Securities.

Agreement or otherwise, or delay by a party in exercising such right or remedy,
shall not operate as a waiver thereof.

         (d) This Agreement shall be governed by and interpreted in accordance

shall be brought and maintained exclusively in the state or Federal courts of
the State of California, sitting in the City of Los Angeles. The Company hereby
expressly and irrevocably submits to the jurisdiction of the state and federal
Courts of the State of California for the purpose of any such litigation as set

such litigation brought in any such court referred to above and any claim that

that the Company has or hereafter may acquire any immunity from jurisdiction of
any court or from any legal process (whether through service or notice,
attachment prior to judgment, attachment in aid of execution or otherwise) with
respect to itself or its property, the Company hereby irrevocably waives such
immunity in respect of its obligations under this Agreement and the related
agreements entered into in connection herewith.

         (e) If any provision of this Agreement shall be invalid or
unenforceable in any jurisdiction, such invalidity or unenforceability shall not
affect the validity or enforceability of the remainder of this Agreement or the
validity or enforceability of this Agreement in any other jurisdiction.

         (f) Subject to the requirements of Section 9 hereof, this Agreement
shall inure to the benefit of and be binding upon the successors and assigns of

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

         (i) This Agreement may be executed in one or more counterparts, each of

same agreement. This Agreement, once executed by a party, may be delivered to

         (j) The Company acknowledges that any failure by the Company to perform
its obligations under Section 3(a) hereof, or any delay in such performance
could result in loss to the Investors, and the Company agrees that, in addition
to any other liability the Company may have by reason of such failure or delay,
the Company shall be liable for all direct damages caused by any such failure or
delay, unless the same is the result of force majeure. Neither party shall be
liable for consequential damages.

         (k) This Agreement, the Securities Purchase Agreement and the other
documents referenced therein constitute the entire agreement among the parties

promises, warranties or undertakings, other than those set forth or referred to
herein. This Agreement supersedes all prior agreements and understandings among
the parties hereto with respect to the subject matter hereof. This Agreement may
be amended only by an instrument in writing signed by the party to be charged
with enforcement thereof.

         (l) Any default by an individual Investor hereunder or any related
agreement, including, without limitation, the Securities Purchase Agreement,
shall not be deemed a default by any other Investor and shall not excuse the
Company's performance hereunder or thereunder with respect to the non-defaulting
Investors.

         (m) In the event of any action for breach of or to enforce or declare
rights under any provision of this Agreement, the prevailing party shall be
entitled to reasonable attorneys' fees and costs, to be paid by the losing
party.
