any  agent  of  the Company may treat the person in whose name this Debenture is

Price  on  the  Closing  Date)(the  "Set Price")(subject to adjustment for stock
splits  and  the  like) and (ii) 80% of the Market Price on the Conversion Date;

               6.     Intentionally  omitted.

               7.     On  the  Maturity  Date, provided that (i) the closing bid
price of the Common Stock is greater than $7.00 for ten (10) consecutive Trading
Days,  (ii)  the  trading  volume  of  the  Common Stock on the Principal Market
exceeds  100,000  shares  of  Common  Stock  on  such Trading Days and (iii) the
Registration  Statement  has  been  effective  during  such ten (10) consecutive

                                        2
<PAGE>
Section  3  hereof.  Conversion  shall  be  deemed  to  have  occurred as of the
Conversion  Date,  which  shall  be the conversion date set forth in the notice,
which  shall  not  be prior to the date the notice is tendered.  Upon receipt of
the  notice,  the  Holder  shall promptly tender the Debenture for conversion to
shares  as  provided  in  Section  8  of  this Agreement.  In the event that the
foregoing  conditions  to  this  Section 7 are not met, the Company will pay the
principal  of and any accrued but unpaid interest due upon this Debenture on the
Maturity  Date,  less  any  amounts  required  by  law  to  be  deducted, to the
registered  holder  of  this  Debenture and addressed to such holder at the last
address  appearing  on  the  Debenture  Register

               8.     (a)     Conversion  shall  be  effectuated by surrendering
this  Debenture  to the Company (if such Conversion will convert all outstanding
principal)  together  with  the  form  of  conversion  notice attached hereto as
Exhibit A (the "Notice of Conversion"), executed by the Holder of this Debenture
evidencing  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 be paid in cash as set forth
above.  No  fraction of a share or scrip representing a fraction of a share 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 the
Notice  of  Conversion  duly executed to the Company.  Facsimile delivery of the
Notice  of Conversion shall be accepted by the Company at facsimile number (714)
937-2485.:  Charles  C.  Bream.  Certificates  representing  Common  Stock  upon
conversion  will  be  delivered to the Holder within three (3) Trading Days from
the  date  the  Notice  of  Conversion is delivered to the Company.  Delivery of
shares  upon  conversion shall be made to the address specified by the Holder in
the  Notice  of  Conversion.

                    (b)     The Company understands that a delay in the issuance
of  shares  of  Common  Stock upon a conversion beyond the three (3) Trading Day
period  described in Paragraph 8(a) could result in economic loss to the Holder.
As  compensation  to  the  Holder  for such loss, the Company agrees to pay late
payments  to  the  Holder  for  late  issuance  of  shares  of Common Stock upon
conversion  in  accordance with the following schedule (where "No.  Trading Days
Late"  is  defined  as  the number of Trading Days beyond three (3) Trading Days
from  the  date  the  Notice  of  Conversion  is  delivered  to  the  Company).

               The  Company shall pay any payments incurred under this Paragraph
8(b)  in  immediately  available  funds upon demand.  Nothing herein shall limit
Holder's  right  to  pursue  injunctive  relief  and/or  actual  damages for the
Company's  failure  to  issue and deliver Common Stock to the holder, including,
without  limitation,  the  Holder's  actual losses occasioned by any "buy-in" of
Common  Stock  necessitated  by such late delivery.  Furthermore, in addition to
any  other  remedies which may be available to the Holder, in the event that the
Company  fails  for any reason to effect delivery of such shares of Common Stock
within  three  (3)  Trading  Days  from  the  date  the  Notice of Conversion is
delivered  to  the  Company,  the Holder will be entitled to revoke the relevant
Notice  of  Conversion  by  delivering  a  notice to such effect to the Company,
whereupon  the Company and the Holder shall each be restored to their respective
positions  immediately  prior  to  delivery of such Notice of Conversion, and in
such  event  no  late  payments  shall  be due in connection with such withdrawn
conversion.

               (c)     If  at  any  time (a) the Company challenges, disputes or
denies  the  right of the Holder to effect the conversion of this Debenture into
Common Stock or otherwise dishonors or rejects any Notice of Conversion properly
delivered in accordance with this Paragraph 8 or (b) any Company stockholder who
is  not  and  has  never  been  an  Affiliate  (as defined in Rule 405 under the
Securities  Act  of  1933,  as  amended) of the Holder obtains a judgment or any
injunctive  relief  from  any  court  or  public or governmental authority which
denies,  enjoins,  limits,  modifies, delays or disputes the right of the holder
hereof  to  effect  the conversion of this Debenture into Common Stock, then the
Holder  shall  have  the  right,  by  written  notice, to require the Company to
promptly  redeem  this  Debenture  for  cash  at a redemption price equal to one
hundred  fifty percent (150%) of the outstanding principal amount hereof and all
accrued  and  unpaid  interest hereon.  Under any of the circumstances set forth
above,  the  Corporation  shall  indemnify  and  hold harmless the holder and be
responsible  for  the payment of all costs and expenses of the holder, including
its  reasonable  legal  fees and expenses, as and when incurred in disputing any
such action or pursuing its rights hereunder (in addition to any other rights of
the holder).  In the event a Holder of this Debenture shall elect to convert any
or  all  of  the outstanding principal amount hereof, the Company may not refuse
conversion  based  on  any  claim  that  the  Holder  or  any  one associated or
affiliated  with the Holder of has been engaged in any violation of law, unless,
an  injunction  from a court, on notice, restraining and or enjoining conversion
of  all  or  part  of this Debenture shall have been sought and obtained and the
Company  posts a surety bond for the benefit of the Holder in the amount of 150%
of  the  principal amount of this Debenture outstanding, which is subject to the
injunction,  which  bond  shall  remain  in  effect  until  the  completion  of
arbitration/litigation of the dispute and the proceeds of which shall be payable
to  such  holder  of  any  shares of Series A Convertible Preferred Stock to the
extent  it  obtains  judgment.  In  the  absence of an injunction precluding the
same,  the  Company  shall  issue  shares  upon  a  properly noticed conversion.

               9.     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  is  a  direct
obligation  of  the  Company.

               10.     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, employee,
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.

               11.     In case of any (1) merger or consolidation of the Company
with or into another Person, or (2) sale by the Company of more than one-half of
the  assets of the Company (on an as valued basis) in one or a series of related
transactions,  the Holder shall have the right to (A) deem such an occurrence an

Event  of Default and exercise its rights of prepayment pursuant to Paragraph 14
herein,  (B)  convert  its  aggregate  principal  amount  of this Debenture then
outstanding  into  the  shares  of stock and other securities, cash and property
receivable  upon  or deemed to be held by holders of Common Stock following such
merger,  consolidation or sale, and the Holder shall be entitled upon such event
or  series  of  related  events  to  receive such amount of securities, cash and
property  as  the  shares  of  Common  Stock into which such aggregate principal
amount  of  this  Debenture  could have been converted immediately prior to such
merger, consolidation or sales would have been entitled, or (C) in the case of a
merger  or  consolidation,  (x)  require the surviving entity to issue shares of
convertible preferred stock or convertible debentures with such aggregate stated
value  or  in  such  face  amount,  as  the  case may be, equal to the aggregate
principal amount of this Debenture then held by the Holder, plus all accrued and
unpaid  interest  and  other amounts owing thereon, which newly issued shares of
preferred stock or debentures shall have terms identical (including with respect
to  conversion) to the terms of this Debenture (except, in the case of preferred
stock,  as  may  be required to reflect the differences between equity and debt)
and  shall be entitled to all of the rights and privileges of the Holder of this
Debenture  set  forth herein and the agreements pursuant to which this Debenture
was  issued  (including,  without  limitation,  as  such  rights  relate  to the
acquisition,  transferability,  registration and listing of such shares of stock
other  securities issuable upon conversion thereof), and (y) simultaneously with
the  issuance  of  such  convertible  preferred stock or convertible debentures,
shall  have  the  right to convert such instrument only into shares of stock and
other  securities,  cash  and  property  receivable upon or deemed to be held by
holders of Common Stock following such merger or consolidation.   In the case of
clause  (C),  the  conversion  price  applicable  for the newly issued shares of
convertible  preferred  stock  or convertible debentures shall be based upon the
amount  of  securities,  cash and property that each share of Common Stock would
receive in such transaction and the Conversion Price in effect immediately prior
to  the  effectiveness  or  closing date for such transaction.  The terms of any
such merger, sale or consolidation shall include such terms so as to continue to
give the Holder the right to receive the securities, cash and property set forth
in  this  Paragraph upon any conversion or redemption following such event. This
Paragraph  shall  similarly  apply  to  successive  such  events.

               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  shall  be  governed  by and construed in
accordance with the laws of the State of New York.  Each of the parties consents
to  the jurisdiction of the federal courts whose districts encompass any part of
the City of New York or the state courts of the State of New York sitting in the
City of New York 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  conveniens,  to  the bringing of any such
proceeding  in  such  jurisdictions.

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

               b.   Any of the material  representations  or warranties  made by
                    the  Company  herein,   in  the  Purchase   Agreement,   the
                    Registration   Rights   Agreement,   or  in  any  agreement,

                    furnished by the Company in  connection  with the  execution
                    and delivery of this  Debenture  or the  Purchase  Agreement
                    shall be false or misleading in any material  respect at the
                    time made; or

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 kind, 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 or any other rights or remedies afforded by law.

                    15.     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.

                    16.     In no event shall the Holder be permitted to convert
this  Debenture  for shares of Common Stock upon which, (x) the number of shares
of Common Stock owned by such Holder (other than shares of Common Stock issuable
upon conversion of this Debenture) plus (y) the number of shares of Common Stock
issuable  upon conversion of this Debenture, would be equal to or exceed 9.9% of
the  number  of  shares  of  Common Stock then issued and outstanding, including
shares  issuable  upon  conversion  of  this Debenture held by such Holder after
application of this Paragraph 16.  As used herein, beneficial ownership shall be
determined  in  accordance  with Section 13(d) of the Securities Exchange Act of
1934,  as amended, and the rules and regulations thereunder.  To the extent that
the  limitation  contained  in  this  Paragraph 16 applies, the determination of
whether  this Debenture is convertible (in relation to other securities owned by
the  Holder) and of which a portion of this Debenture is convertible shall be in
the sole discretion of such Holder, and the submission of a Notice of Conversion
shall  be  deemed to be such Holder's determination of whether this Debenture is
convertible  (in relation to other securities owned by such holder) and of which
portion of this Debenture is convertible, in each case subject to such aggregate
percentage  limitation,  and  the  Company shall have no obligation to verify or
confirm  the  accuracy of such determination.  Nothing contained herein shall be
deemed  to  restrict the right of a holder to convert this Debenture into shares
of  Common Stock at such time as such conversion will not violate the provisions
of  this Paragraph 16.  The provisions of this Paragraph 16 may be waived by the
Holder  of  this  Debenture  upon  not  less  than  75 days' prior notice to the
Company,  and  the provisions of this Paragraph 16 shall continue to apply until
such 75th day (or such later date as may be specified in such notice of waiver).
No  conversion of this Debenture in violation of this Paragraph 16 but otherwise
in  accordance  with  this Debenture shall affect the status of the Common Stock
issued upon such conversion as validly issued, fully-paid and nonassessable.  If
instead  of receiving cash on the Maturity Date the Holder instead exercises its
right  to  convert  this  Debenture into Common Stock pursuant to Paragraph 3 by
delivery  of  a  Notice  of  Conversion  prior  to  receipt of payment, and such
conversion  would  cause  the  limit  contained  in  the  first sentence of this
Paragraph 16 to be exceeded, such conversion of this Debenture shall occur up to
such  limit  and  the  remaining  unconverted portion of this Debenture shall be
converted  into  Common  Stock  (1)  in  accordance  with one or more Notices of
Conversion  delivered  by  the  Holder  or  (2) 65 days after the Maturity Date,
whichever  is  earlier.  Notwithstanding  anything  contained  herein  to  the
contrary,  no  interest  shall  accrue  after  the  Maturity  Date  on  any such
unconverted  portion  of  this  Debenture.
