PROMISE  TO  PAY,  PENN OCTANE CORPORATION ("Borrower") promises to pay to Bay
Area  Bank  ("Lender"),  or  order,  in  lawful  money of the United States of
America,  the  principal amount of Two Hundred Fifty One Thousand Four Hundred
Ninety  Five  &  00/100  Dollars  ($251,495.00), together with interest on the
unpaid  principal  balance  from  April  2,  1997,  until  paid  in  full.

PAYMENT.   Subject to any payment changes resulting from changes in the Index,
Borrower will pay this loan in accordance with the following payment schedule:

     STAND-BY  LETTER  OF  CREDIT  IN  FAVOR  OF COUNTY SANITATION DISTRICT OF
ORANGE  COUNTY.    PAYMENT  IS  ON  DEMAND.

Interest on this Note is computed on a 365/365 simple interest basis; that is,
by applying the ratio of the annual interest rate over the number of days in a
year,  multiplied  by  the  outstanding  principal  balance, multiplied by the
actual number of days the principal balance is outstanding.  Borrower will pay
Lender  at  Lender's  address shown above or at such other place as Lender may
designate  in writing.  Unless otherwise agreed or required by applicable law,
payments  will  be  applied  first to any unpaid collection costs and any late
charges,  then  to  any unpaid interest and any remaining amount to principal.

VARIABLE  INTEREST  RATE.  The interest rate on this Note is subject to change
from  time  to time based on changes in an independent index which is the Rate
as  listed  in  The  Wall Street Journal "Money Rates" section, referred to as
"Prime  Rate"  (the "Index").  The index is not necessarily the lowest charged
by  Lender  on its loans.  If the Index becomes unavailable during the term of
this  loan,  Lender may designate a substitute index after notice to Borrower.
Lender  will  tell  Borrower  the  current index rate upon Borrower's request.
Borrower  understands that Lender may make loans based on other rates as well.
The  interest  rate  change  will  not occur more often than each month and is
based  ont  he  published rate in effect on the first business day each month.
If  more  than  one  Prime  Rate  is published, the prime rate chosen shall be
solely  at  Bank's  option.    The  Index  currently is 8.500% per annum.  The
interest  rate to be applied to the unpaid principal balance of this Note will
be at a rate of 3,000 percentage points over the Index, resulting in a current
rate  of 11.500% per annum.  NOTICE:  Under no circumstances will the interest
rate  on  this  Note  be more than the maximum rate allowed by applicable law.
Whenever  increases  occur  in the interest rate, Lender at its option, may do
one  or  more  of  the  following:  (a) increase Borrower's payments to ensure
Borrower's loan will pay off by its original final maturity date, (b) increase
Borrower's  payments  to  cover  accruing interest, (c) increase the number of
Borrower's  payments,  and (d) continue Borrower's payments at the same amount
and  increase  Borrower's  final  payment.

DEFAULT.    Borrower  will be in default if any of the following happens:  (a)
Borrower  fails to make any payment when due.  (b) Borrower breaks any promise
Borrower  has  made  to Lender, or Borrower fails to comply with or to perform
when  due any other term, obligation, covenant, or condition contained in this
Note  or any agreement related to this Note, or in any other agreement or Loan
Borrower  has  with  Lender.    (c)  Any  representation  or statement made or
furnished to Lender by Borrower or on Borrower's behalf is false or misleading
in  any  material  respect  either  now or at the time made or furnished.  (d)
Borrower becomes insolvent, a receiver is appointed for any part of Borrower's
property,  Borrower  makes an assignment for the creditor tries to take any of
Borrower's  property  on  or  in which Lender has a lien or security interest.
This  includes  a  garnishment of any of Borrower's accounts with Lender.  (f)
any  guarantor  dies  or  any  of  the  other events described in this default
section  occurs  with  respect  to any guarantor of this Note.  (g) A material
adverse  change  occurs  in Borrower's financial condition, or Lender believes
the  prospect  of  payment  or  performance  of  the Indebtedness is impaired.

If  any  default,  other than a default in payment, is curable and if Borrower
has  not  been  given  a notice of a breach of the same provision of this Note
within  the  preceding  twelve  (12)  months, it may be cured (and no event of
default  will  have occurred) if Borrower, after receiving written notice from
Lender  demanding  cure  of  such default (a) cures the default within fifteen
(15) days; or (b) if the cure requires more than fifteen (15) days immediately
initiates  steps  which  Lender  deems  in  Lender's  sole  discretion  to  be
sufficient  to  cure  the  default  and thereafter continues and completes all
reasonable  and  necessary  steps  sufficient to produce compliance as soon as
reasonably  practical.

LENDER'S RIGHTS.  Upon default, Lender may declare the entire unpaid principal
balance  on  this Note and all accrued unpaid interest immediately due without

pay  all  amounts  declared due pursuant to this section, including failure to
pay  upon  final maturity, Lender, at its option, may also, if permitted under

percentage points over the Index.  Lender may hire or pay someone else to help
collect  this  Note  if  Borrower does not pay.  Borrower also will pay Lender
that  amount.    This  includes,  subject  to any limits under applicable law,
