corporation  (the  "Company").

     WHEREAS, the Company wishes to sell and each Purchaser wishes to purchase
(i)  a  10%  Promissory Note in such principal amount as is set forth opposite
such  Purchaser's  name  on  Schedule  I hereto, due on the earlier of (A) the

"Financing")  and  (B)  June  30,  1998,  substantially in the form annexed as
Exhibit  1  hereto  (the  "Note"), and (ii) warrants to purchase Common Stock,

21,  2000  at $6.00 per share of Common Stock (subject to adjustment), in such
number  as  is  set  forth opposite such Purchaser's name on Schedule I hereto
(the  "Warrant  Shares"),  substantially  in the form of Exhibit 2 hereto (the
"Warrants"; the Note and the Warrants being herein collectively referred to as
the  "Securities");  and

     WHEREAS,  the  Company  and each of the Purchasers desire to enter into a
Registration  Rights  Agreement  with  respect  to  the  Warrant  Shares,
substantially  in  the  form  annexed  as  Exhibit 3 hereto (the "Registration
Rights  Agreement"),  all  on  the  terms  and  conditions  set  forth herein;

     NOW, THEREFORE, in consideration of the agreements and obligations herein
contained,  the  Purchasers  and  the  Company  hereby  agree  as  follows:

     1.         Purchase and Sale of the Securities.  Subject to the terms and
                -----------------------------------
conditions  set  forth  in  this Agreement, the Company agrees to sell to each
Purchaser,  and  each Purchaser agrees, severally and not jointly, to purchase
from  the Company, such Securities set forth opposite such Purchaser's name on
Schedule  I hereto for a purchase price equal to the amount set forth opposite
such  Purchaser's  name  on  Schedule  I  hereto.

     2.     The Closing.  The closing (the "Closing") of the purchase and sale
            -----------
of  the  Securities  shall  take place on October 21, 1997 at 10:00 A.M. local
time  at  the  offices  of the Company in Redwood City, California, or at such
other  time  and  place as the Company and the Purchasers shall agree.  At the
Closing,  each  Purchaser  shall  deliver  to  the  Company  payment  for  the
Securities  being  purchased  by such Purchaser in immediately available funds
and  the  Company  shall  deliver a Note and Warrants to each Purchaser in the
amount  and  number  set  forth  opposite  each Purchaser's name on Schedule I
hereto.

     3.      Registration Rights.  The Purchasers shall have such registration
             -------------------
rights with respect to the Warrant Shares as are set forth in the Registration
Rights  Agreement.

     4.     Representations and Warranties of the Company,  As of the Closing,
            ---------------------------------------------
the  Company  represents  and  warrants  that:

          (a)          the  Company  is  a corporation duly organized, validly
existing and in good standing under the laws of the State of Delaware, and has
the  requisite  corporate  power  and  authority  to  execute and deliver this
Agreement  and  to  perform  its  obligations  hereunder;

          (b)       the execution, delivery and performance of this Agreement,
and  the  sale and delivery of the Securities have been duly authorized by all
necessary  corporate  action on the part of the Company and do not violate any
covenant  contained  in  any  agreement  to  which the Company is a party; and

          (c)          the  Warrant  Shares,  when issued upon exercise of the
Warrants  and payment therefor, will be legally and validly issued, fully paid
and  nonassessable.

     5.         Representations and Warranties of the Purchasers.  Each of the
                ------------------------------------------------
Purchasers, severally and not jointly, represents and warrants to the Company,
as  to  itself,  as  follows:

          (a)          General:
                       -------

               (i)     The Purchaser has all requisite authority to enter into
this  Agreement and to perform all of the obligations required to be performed
by  it  hereunder.

               (ii)     Neither the Company nor any person acting on behalf of
the  Company  has  offered or sold the Securities to the Purchaser by means of
any  form  of  general solicitation or general advertising.  The Purchaser has
not  received,  paid  or  given,  directly  or  indirectly,  any commission or
remuneration  for  or on account of any sale, or the solicitation of any sale,
of  the  Securities.

          (b)          Information  Concerning  the  Company:
                       -------------------------------------

               (i)          The  Purchaser  is  familiar with the business and
financial  condition,  properties,  operations  and  prospects of the Company.

               (ii)          The  Purchaser  has been given full access to all
material  information  concerning  the  condition,  properties, operations and
prospects of the Company.  The Purchaser and his advisors (if any) have had an
opportunity  to ask questions of, and to receive information from, the Company
and  persons  acting  on its behalf concerning the terms and conditions of the
Purchaser's  investment  in  the  Securities,  and  to  obtain  any additional
information  necessary  to  verify  the  accuracy  of the information and data
received  by  the  Purchaser.    The  Purchaser  is satisfied that there is no
material  information  concerning  the  condition,  properties, operations and
prospects  of  the  Company  of  which  Purchaser  is  unaware.

               (iii)     The Purchaser has made, either alone or together with
his  advisors  (if  any),  such  independent investigation of the Company, its
management,  and  related  matters  as  the  Purchaser  deems  to  be,  or the
Purchaser's  advisors  (if  any) have advised to be, necessary or advisable in
connection  with  this investment; and the Purchaser and his advisors (if any)
have  received  all  information and data which the Purchaser and his advisors
(if  any) believe to be necessary in order to reach an informed decision as to
the  advisability  of  investing  in  the  Securities.

               (iv)         The Purchaser understands that all the Purchaser's
representations  and  warranties contained in this Agreement will be deemed to
have  been  reaffirmed  and  confirmed  as  of  the  Closing.

               (v)          The Purchaser understands that the purchase of the
Securities involves various risks, including the risk that it is unlikely that
any  market  will  exist  for  any resale of the Note or the Warrants and that
resale  of the Note, the Warrants and the Warrant Shares will be restricted as
herein  provided.

          (c)          Status  of  Purchaser:
                       ---------------------

               (i)     The Purchaser either alone or with Purchaser's advisors
(if  any)  has such knowledge, skill and experience in business, financial and
investment  matters  as to be capable of evaluating the merits and risks of an
investment  in the Securities.  To the extent that the Purchaser has deemed it
appropriate  to  do so, the Purchaser has retained at Purchaser's own expense,
and relied upon, appropriate professional advice regarding the investment, tax
and  legal  merits  and  consequences  of  this Agreement and owning the Note,
Warrants  and  Warrant  Shares,  as  the  case  may  be.

          (d)          Restrictions  on  Transfer  or  Sale
                       ------------------------------------

               (i)          The  Purchaser is acquiring the Securities and any
shares  of Common Stock purchased upon exercise of the Warrants solely for its
own account, for investment purposes, and not with a view to, or for resale in
connection  with, any distribution of the Note, the Warrants or such shares of
Common  Stock.   The Purchaser understands that neither the Note, the Warrants
nor such underlying Common Stock have been registered under the Securities Act
of  1933,  as  amended  (the  "Securities Act"), or the securities laws of any
state  (collectively  referred  to  as  "State  Securities Laws") by reason of
specific exemptions under the provisions thereof which depend in part upon the
investment  intent  of  the Purchaser and of the other representations made by
the  Purchaser  in this Agreement.  The Purchaser understands that the Company
is relying upon the representations and agreements contained in this Agreement
(and any supplemental information) for the purpose of determining whether this
transaction  meets  the  requirements  for  such  exemptions.

               (ii)      The Purchaser understands that the Note, the Warrants
and  such underlying Common Stock are "restricted securities" under applicable
federal  securities  laws  and  that  the  Securities Act and the rules of the
Securities  and  Exchange  Commission  (the "Commission") provide in substance
that the Purchaser may dispose of such securities or any of them only pursuant
to  an  effective  registration  statement  under  the  Securities  Act  or an
exemption  therefrom,  and  understands that the Company has no obligations or
intentions to register any of such securities thereunder, or to take any other
action  so  as  to  permit sales pursuant to the Securities Act, except as set
forth  in  the  Registration  Rights  Agreement.    Accordingly, the Purchaser
understands  that under the Commission's rules, unless disposed of pursuant to
an  effective  registration  statement under the Securities Act, the Purchaser
may  dispose  of  the  Note,  Warrants  and  underlying  Common  Stock only in
accordance  with  the  provisions of Rule 144 under the Securities Act, to the
extent  available,  or  in  "private  placements"  which  are  exempt  from
registration  under  the  Securities  Act,  in which event the transferee will
acquire  "restricted  securities"  subject  to  the same limitations as in the
hands  of  the  Purchaser.    As  a  consequence,  absent  such  an  effective
registration  statement  under  the  Securities Act, the Purchaser understands
that  it  may  be required to bear the economic risks of the investment in the
Securities (and the underlying Common Stock) for an indefinite period of time.

               (iii)          The  Purchaser agrees that (a) it will not sell,
assign, pledge, give, transfer, of otherwise dispose of the Note, the Warrants
or  such underlying Common Stock or any interest in any thereof or therein, or
make  any  offer  or  attempt  to  do any of the foregoing, except pursuant to
registration  of  such  securities under the Securities Act and any applicable
State Securities Laws or in a transaction which, in the opinion of counsel for
the  Purchaser satisfactory to the Company (which requirement may be waived by
the  Company  upon  advice  of  counsel),  is  exempt  from  the  registration
provisions of the Securities Act and any applicable State Securities Laws; (b)
the Note and the Warrants and any certificate(s) representing shares of Common
Stock  issued upon exercise of the Warrants may bear a legend making reference
to  the foregoing restrictions; and (c) the Company and any transfer agent for
shares  of  its  Common  Stock  shall  not  be  required to give effect to any
purported  transfer  of any of such securities except upon compliance with the
foregoing  restrictions.

               (iv)       The registration rights granted to the Purchaser  in
the  Registration  Rights  Agreement  are  not  assignable  or  otherwise
transferrable  by  the  Purchaser.    In  no event shall any sale, assignment,
pledge or transfer of the Warrants or Common Stock issuable upon conversion of
the  Warrants  by  the Purchaser to a transferee give rise to any rights under
the  Registration  Rights  Agreement.

     6.          Conditions  to Obligations of Purchaser and the Company.  The
                 -------------------------------------------------------
obligations  of  each  of  the Purchasers under this Agreement to purchase any
Securities  specified  herein  and  of  the  Company  to sell and deliver such
Securities  are  subject to the satisfaction at or prior to the Closing of the
following  conditions  precedent:

          (a)      The representations and warranties of the Company contained
in  Section  4 hereof and of the Purchaser contained in Section 5 hereof shall
be  true  and  correct  on and as of the Closing in all respects with the same
effect as though representations and warranties had been made on and as of the
Closing.

          (b)       The Company shall have received from the Purchaser and the
Purchaser  shall  have  received from the Company a certificate from the other
party  (and,  in  the  event  such  party  is a corporate entity, an executive
officer  of  such party) to the effect that its representations and warranties
are    still  valid.

          (c)       The Company and the Purchaser shall each have executed and
delivered  the  Registration  Rights  Agreement.

     7.     Mandatory Prepayment.  If at any time prior to the maturity of the
            --------------------
Note,  there  shall have occurred a closing of a Financing, the Company shall,
within ten (10) business days of the receipt of such proceeds, prepay (without
penalty)  all  of the Note, including any accrued and unpaid interest thereon,
at  the  office of the Company in Redwood City, California or such other place
as  the  Purchasers  and  the  Company  may  agree.

     8.      Fee.  In connection with the purchase and sale of the Securities,
             ---
Pennsylvania  Merchant  Group Ltd, as placement agent for the Company ("PMG"),
shall  receive  at  the  Closing a fee from the Company equal to $120,000 plus
reimbursement  of  expenses,  not  to  exceed  $25,000.

     9.          Waiver, Amendment.  Neither this Agreement nor any provisions
                 -----------------
hereof  shall  be  modified,  changed,  discharged  or terminated except by an
instrument  in  writing  signed  by the party against whom any waiver, change,
discharge  or  termination  is  sought.

     10.         Assignability.  Neither this Agreement nor any right, remedy,
                 -------------
obligation  or  liability  arising  hereunder  or  by  reason  hereof shall be
assignable  by either the Company or any Purchaser hereunder without the prior
written  consent  of  the other party, which consent shall not be unreasonably
withheld.

     11.          Applicable  Law.    This  Agreement shall be governed by and
                  ---------------
construed  in  accordance with the law of the State of New York, regardless of
the  law  that  might  be  applied  under  principles  of  conflicts  of  law.

     12.          Section  and Other Headings.  The section and other headings
                  ---------------------------
contained  in  this  Agreement  are  for reference purposes only and shall not
affect  the  meaning  or  interpretation  of  this  Agreement.

     13.        Counterparts.  This Agreement may be executed in any number of
                ------------
counterparts,  each of which when so executed and delivered shall be deemed to
be  an  original  and  all of which together shall be deemed to be one and the
same  agreement.

                                ---------------

                           Redwood City, California


     FOR  VALUE  RECEIVED,  PENN  OCTANE  CORPORATION,  a Delaware corporation
("Company"),  promises  to  pay  to  __________________________,  a
__________________,    or  registered assigns ("Holder"), at the office of the
Company  in  Redwood  City,  California  or  such  other  place  as Holder may
designate  in writing at least three business days prior to the date fixed for
such  payment,  the entire principal sum of _____________________($_________),
together with interest thereon, on the earlier of (i) a date determined by the
Company  within  ten  (10)  business  days  of  the closing date of any public
offering  of  debt  or  equity  securities  of  the  Company, resulting in net
proceeds to the Company in excess of $5,000,000, and (ii) June 30, 1998,  (the
"Payment  Date"),  at  which  time  all  principal  and any accrued and unpaid
interest thereon shall be due and owing.  This Note shall accrue interest from
the date hereof at the rate of ten (10%) per annum, payable quarterly on March
31,  June  30,  September  30  and December 31 in each year.  This Note may be
prepaid  at  any  time prior to maturity without penalty in an amount equal to
the  principal  amount  hereof  plus  interest  thereon  to the date fixed for
prepayment.

     All  payments  of  principal  and  interest hereunder shall be payable in
lawful  money  of  the  United  States.

     The  Company  shall be in default hereunder upon the occurrence of any of
the  following  events:  (i) the failure by the Company to make any payment of
principal or interest when due hereunder and such failure shall have continued
for  a  period  of  ten  (10)  days; (ii) the commencement by the Company of a
voluntary  case  in  a  bankruptcy  or insolvency proceeding or the entry of a
decree  or order by a court of competent jurisdiction adjudicating the Company
a bankrupt or the appointment of a receiver or trustee of the Company upon the
application of any creditor in an insolvency or bankruptcy proceeding or other
creditor's  suit;  (iii) the entry of an order for relief approving a petition
for  reorganization or arrangement filed against the Company under the Federal
bankruptcy  laws  and  such  order  remains in force and unvacated thirty (30)
days;  (iv) an assignment for the benefit of creditors by the Company; (v) the
occurrence  of any event of default under the terms of any indebtedness of the
Company  for  borrowed  money  in  excess  of  $50,000,  provided  that  such
indebtedness  has  been  accelerated  because  of  such  default;  or (vi) the
existence  of  any judgment in excess of $50,000 against, or any attachment of
material  property,  of  the  Company.

     At  any  time  when an event of default hereunder shall have occurred and
shall  be continuing, Holder at its option may accelerate the maturity of this
Note  and  declare  all  of the indebtedness thereof to be immediately due and
payable,  together  with  accrued interest thereon, and payment thereof may be
enforced  by  suit  or  other  process  of  law.

     If  this  Note  is  not  paid  when  due,  whether  at  maturity  or  by
acceleration, the Company agrees to pay all reasonable costs of collection and
such  costs  shall  include  without limitation all costs, attorneys' fees and
expenses  incurred  by  Holder  hereof  in  connection  with  any  insolvency,
bankruptcy,  reorganization,  arrangement  or  similar  proceedings  involving
Holder,  or  involving  any  endorser  or  guarantor  hereof, which in any way
affects  the  exercise  by Holder hereof of its rights and remedies under this
Note.

     Presentment, demand, protest, notice of protest, dishonor and non-payment
of  this  Note  and  all  notices  of  every  kind  are  hereby  waived.

     The  terms  "Company"  and  "Holder"  shall be construed to include their
respective heirs, personal representatives, successors, subsequent holders and
permitted  assigns.

     This  Note  shall  be  governed by, and construed in accordance with, the
laws  of the State of New York without giving effect to such state's conflicts
of  law  provisions.    Each of the parties hereto irrevocably consents to the
jurisdiction and venue of the federal and state courts located in the State of
New  York,  County  of  New  York.

                         COMMON STOCK PURCHASE WARRANT
                          Void after October __, 2000

                                             Warrant to Purchase ______ Shares
                                               of Common Stock, $.01 par value
                                                    of Penn Octane Corporation

                        PENN OCTANE CORPORATION (POCC)

This  is  to  Certify  That,  FOR  VALUE  RECEIVED,

                              [Name of Purchaser]

or  registered  assign(s)  (herein referred to as the "Holder") is entitled to
purchase,  subject  to  the provisions hereof, from PENN OCTANE CORPORATION, a
Delaware corporation (the "Company"), but not later than 5:00 p.m., California
time,  on  October __, 2000 (or, if such date is not a Business Day in Redwood
City,  California,  then  on the next succeeding day which shall be a Business
Day),  _______  shares  of  Common  Stock, $.01 par value, of the Company (the
"Common Stock") at an exercise price of $6.00 per share, subject to adjustment
as  to  number  of  shares and purchase price as set forth in Section 6 below.
The  exercise  price  of  a share of Common Stock in effect at any time and as
adjusted  from  time  to  time  is  hereinafter  sometimes  referred to as the
"Exercise  Price".   For purposes of this Warrant, a "Business Day" shall mean
any day other than a Saturday, a Sunday or a day on which banking institutions
in  New  York, New York, or in Redwood City, California, are authorized by law
or  regulation  to  close.

The  shares  of  Common  Stock  issuable  upon  exercise  of  the Warrants are
sometimes  herein  called  the  "Warrant  Stock."

     1.     Exercise of Warrant.  This Warrant may be exercised in whole or in
            -------------------
part at any time and from time to time by presentation and surrender hereof to
the Company at its principal office with the Purchase Form annexed hereto duly
executed  and  accompanied  by  payment  of  the Exercise Price in immediately
available  funds  for  the  number  of shares specified in such form.  If this
Warrant  is  exercised in part only, the Company shall, upon surrender of this
Warrant  for  cancellation,  execute  and deliver a new Warrant evidencing the
right  of  the  Holder  to  purchase  the  balance  of  the shares purchasable
hereunder.    Upon receipt by the Company of this Warrant at the office of the
Company,  in  proper form for exercise, accompanied by payment of the Exercise
Price,  the Holder shall be deemed to be the holder of record of the shares of
Common  Stock  issuable  upon such exercise, notwithstanding that certificates
representing  such shares of Common Stock shall not then be actually delivered
to  the  Holder.  The issuance of certificates for shares of Common Stock upon
the  exercise  of  this Warrant shall be made without charge to the Holder for
any  issuance  tax  in  respect  thereof (with the exception of any federal or
state  income  taxes  applicable  thereto),  all  such taxes to be paid by the
Company,  it being understood however that the Holder shall be required to pay
any  tax  which  may  be  payable  in  respect of any transfer involved in the
issuance  and  delivery  of  any  certificate in a name other than that of the
Holder.    The  Company  will  at no time close its transfer books against the
transfer  of  this  Warrant  or  the  issuance  of  any shares of Common Stock
issuable upon the exercise of this Warrant in any manner which interferes with
the  timely  exercise  of  this  Warrant.

     2.     Reservation of Shares; Stock Fully Paid.  The  Company agrees that
            ---------------------------------------
at all times there shall be authorized and reserved for issuance upon exercise
of this Warrant such number of shares of its Common Stock as shall be required
for  issuance or delivery upon exercise of this Warrant.  All shares which may
be  issued  upon  exercise  hereof will, upon issuance, and receipt of payment
therefor,  be  duly authorized, validly issued, fully paid and non-assessable.

     3.     Fractional Shares.  This Warrant shall not  be exercisable in such
            -----------------
manner  as  to  require the issuance of fractional shares.  If, as a result of
adjustment in the Exercise Price or the number of shares of Common Stock to be
received  upon  exercise of this Warrant, fractional shares would be issuable,
no such fractional shares shall be issued.  In lieu thereof, the Company shall
pay the Holder an amount in cash equal to such fraction multiplied by the Fair
Market  Value  of a share of Common Stock.  The term "Fair Market Value" shall
mean,  as  of  a  particular  date,  the  market  price  on  such  date.

          For  purposes  of this Warrant, the market price on any day shall be
the  last sale price on such day on the NASDAQ Stock Market, or, if the Common
Stock is not then listed or admitted to trading on the NASDAQ Stock Market, on
such  other  principal  stock  exchange  on which such stock is then listed or
admitted  to  trading,  or,  if  no  sale  takes place on such day on any such
exchange,  the  average  of  the  closing  bid and asked prices on such day as
officially  quoted  on  any such exchange, or, if the Common Stock is not then
listed  or  admitted  to  trading  on  any  stock exchange, the average of the
reported  closing  bid  and  asked  prices on such day in the over-the-counter
market  as  quoted on the National Association of Securities Dealers Automated
Quotation  System or, if not so quoted, then as furnished by any member of the
National  Association of Securities Dealers, Inc. selected by the Company.  If
there  shall  be no meaningful over-the-counter market, then Fair Market Value
shall  be  such  amount, not less than book value, as may be determined by the
Board  of  Directors  of  the  Company.

     4.     Exchange or Assignment of Warrant.  This  Warrant  is exchangeable
            ---------------------------------
without  expense  (other  than applicable transfer taxes) at the option of the
Holder,  upon  presentation  and surrender hereof to the Company for any other
Warrants  of  different denominations entitling the holder thereof to purchase
in  the  aggregate  the  same  number  of  shares  of Common Stock purchasable
hereunder.   Subject to the provisions of Section 12 below and any restriction
on  transfer  applicable  hereto pursuant to the securities laws of the United
States  or  any  State,  upon surrender of this Warrant to the Company with an
assignment  form  duly executed, and funds sufficient to pay any transfer tax,
the  Company  shall,  without charge, execute and deliver a new Warrant in the
name  of the assignee named in such instrument of assignment, and this Warrant
shall  promptly  be  cancelled.   This Warrant may be divided or combined with
other  Warrants  which  carry  the same rights upon presentation hereof at the
principal office of the Company, together with a written notice specifying the
names  and  denominations in which new Warrants are to be issued signed by the
Holder  hereof.   The term "Warrant" as used herein includes any Warrants into
which  this Warrant may be divided or exchanged, and the term "Holder" as used
herein  includes  any  holder  of  any  Warrant into which this Warrant may be
divided  or  for  which  this  Warrant  may  be  exchanged.

     5.     Rights of the Holder.  The  Holder shall not, by virtue hereof, be
            --------------------
entitled  to  any  rights of a stockholder in the Company, either at law or in
equity,  and  the  rights of the Holder are limited to those expressed in this
Warrant.

     6.     Adjustment of Exercise Price and Number of Shares.  The number and
            -------------------------------------------------
kind  of  securities purchasable upon the exercise or exchange of this Warrant
and  the  Exercise Price shall be subject to adjustment from time to time upon
the  occurrence  of  certain  events,  as  follows:

     (a)     Adjustment for Change in Capital Stock.  If at any time after the
             --------------------------------------
date  hereof,  the  Company:

          (A)      pays a dividend or makes a distribution on its Common Stock
in  shares  of  its  Common  Stock;

          (B)         subdivides its outstanding shares of Common Stock into a
greater  number  of  shares;

          (C)          combines  its outstanding shares of Common Stock into a
smaller  number  of  shares;

          (D)        makes a distribution on its Common Stock in shares of its
capital  stock  other  than  Common  Stock;  or

          (E)     issues by reclassification of its Common Stock any shares of
its  capital  stock;

then  the  Exercise  Price in effect immediately prior to such action shall be
adjusted  so  that  the  Holder may receive, upon exercise or exchange of this
Warrant  and payment of the same aggregate consideration, the number of shares
of  capital stock of the Company which the Holder would have owned immediately
following  such  action  if  the Holder had exercised or exchanged the Warrant
immediately  prior  to  such  action.

     The  adjustment  shall become effective immediately after the record date
in  the case of a dividend or distribution and immediately after the effective
date  in  the  case  of  a  subdivision,  combination  or  reclassification.

     (b)     Adjustment for Other Distributions.  If  at  any  time  after the
             ----------------------------------
date hereof, the Company distributes to all holders of its Common Stock any of
its  assets  or  debt securities, the Exercise Price following the record date
shall  be  adjusted  in  accordance  with  the  following  formula:

                            E'=  E   x  M-F
                                        ---
                                         M


where:    E'     =   the  adjusted  Exercise  Price.
          E      =   the Exercise Price immediately prior to the adjustment.
          M      =   the current market price (as defined in (e) below) per
                     share  of Common  Stock  on  the  record  date  of the
                     distribution.

          F      =   the aggregate fair market value (as conclusively
                     determined by the Board  of  Directors of the Company) on
                     the record date of the  assets or debt securities to be
                     distributed divided by the number of outstanding shares
                     of Common  Stock.

     The  adjustment shall be made successively whenever any such distribution
is  made  and shall become effective immediately after the record date for the
determination  of  shareholders  entitled to receive the distribution.  In the
event  that  such  distribution is not actually made, the Exercise Price shall
again be adjusted to the Exercise Price as determined without giving effect to
the  calculation  provided  hereby.    In no event shall the Exercise Price be
adjusted  to  an  amount  less  than  zero.

     This  subsection  does  not apply to cash dividends or cash distributions
paid out of consolidated current or retained earnings as shown on the books of
the  Company  and  paid  in  the  ordinary  course  of  business.

     (c)     Deferral of Issuance or Payment.  In  any  case in which an event
             -------------------------------
covered  by  this  Section  6 shall require that an adjustment in the Exercise
Price  be  made  effective as of a record date, the Company may elect to defer
making  such  adjustment  until the occurrence of such event by (i) issuing to
the Holder, if this Warrant is exercised after such record date but before the
occurrence  of  such event, the shares of Common Stock and other capital stock
of  the Company, if any, issuable upon such exercise, had such adjustment been
made as of the record date, over and above the shares of Common Stock or other
capital stock of the Company, if any, issuable upon such exercise on the basis
of  the  Exercise  Price as unadjusted, and (ii) paying to the Holder by check
any amount in lieu of the issuance of fractional shares pursuant to Section 3.

     (d)     When No Adjustment Required.  No  adjustment  need  be made for a
             ---------------------------
change  in  the  par  value  or  no  par  value  of  the  Common  Stock.

     (e)     Statement of Adjustments.  Whenever the Exercise Price and number
             ------------------------
of  shares of Common Stock purchasable hereunder is required to be adjusted as
provided  herein,  the  Company shall promptly prepare a certificate signed by
its  President or any Vice President and its Treasurer or Assistant Treasurer,
setting  forth,  in reasonable detail, the event requiring the adjustment, the
amount  of  the adjustment, the method by which such adjustment was calculated
(including  a  description  hereunder),  and  the Exercise Price and number of
shares  of  Common  Stock  purchasable  hereunder  after giving effect to such
adjustment,  and shall promptly cause copies of such certificates to be mailed
to  the  Holder.

     (f)     No Adjustment Upon Exercise of Warrants.  No adjustments shall be
             ---------------------------------------
made under any Section herein in connection with the issuance of Warrant Stock
upon  exercise  or  exchange  of  the  Warrants.

     (g)     No adjustment for Small Amounts.  Anything herein to the contrary
             -------------------------------
notwithstanding,  no  adjustment  of  the  Exercise Price shall be made if the
amount of such adjustment shall be less than $.05 per share, but in such case,
any  adjustment  that  would  otherwise  be  required then to be made shall be
carried  forward  and  shall  be  made  at the time and together with the next
subsequent  adjustment which, together with any adjustment so carried forward,
shall  amount  to  $.05  per  share  or  more.

     (h)     Common Stock Defined.  Subject  to  the  provisions  of Section 7
             --------------------
hereof,  shares  issuable  upon exercise or exchange hereof shall include only
shares  of  the class designated as Common Stock of the Company as of the date
hereof  or  shares of any class or classes resulting from any reclassification
or reclassifications thereof or as a result of any corporate reorganization as
provided  for  in  Section  7  hereof.

     7.     Reclassification, Reorganization, Consolidation or Merger.  In the
            ---------------------------------------------------------
event  of  any  reclassification,  capital  reorganization  or other change of
outstanding shares of Common Stock of the Company (other than a subdivision or
combination of the outstanding Common Stock and other than a change in the par
value  of  the Common Stock) or in the event of any consolidation or merger of
the  Company  with  or  into another corporation (other than a merger in which
merger  the  Company is the continuing corporation and that does not result in
any  reclassification,  capital  reorganization or other change of outstanding
shares of Common Stock of the class issuable upon exercise or exchange of this
Warrant) or in the event of any sale, lease, transfer or conveyance to another
corporation  of  the  property  and  assets  of  the Company as an entirety or
substantially  as  an entirety, the Company shall, as a condition precedent to
such  transaction,  cause  effective  provisions to be made so that the Holder
shall  have  the right thereafter, by exercising this Warrant, to purchase the
kind  and  amount  of  shares  of  stock  and  other  securities  and property
(including cash) receivable upon such reclassification, capital reorganization
and other change, consolidation, merger, sale or conveyance by a holder of the
number  of  shares of Common Stock that might have been received upon exercise
or  exchange  of  this  Warrant  immediately  prior  to such reclassification,
capital  reorganization,  change,  consolidation,  merger, sale or conveyance.
Any such provision shall include provisions for adjustments in respect of such
shares  of  stock  and  other  securities and property that shall be as nearly
equivalent  as  may  be  practicable  to  the adjustments provided for in this
Warrant.   The foregoing provisions of this Section 7 shall similarly apply to
successive reclassifications, capital reorganizations and changes of shares of
Common  Stock and to successive consolidations, mergers, sales or conveyances.
In  the  event  that  in  connection  with  any such capital reorganization or
classification,  consolidation,  merger, sale or conveyance, additional shares
of  Common  Stock  shall  be  issued  in exchange, conversion, substitution or
payment, in whole or in part, for, or of, a security of the Company other than
Common  Stock,  any  such  issue  shall be treated as an issue of Common Stock
covered  by  the  provisions  of  subsection  (a)  of  Section  6.

     8.     Notice  to Warrant Holders.  So  long  as  this  Warrant  shall be
            --------------------------
outstanding,  (i)  if  the  Company  shall  pay  any  dividend  or  make  any
distribution  upon its Common Stock, or (ii) if the Company shall offer to the
holders  of  Common  Stock  for subscription or purchase by them any shares of
stock  or securities of any class or any other rights, or (iii) if any capital
reorganization  of  the  Company, reclassification of the capital stock of the
Company,  consolidation  or  merger  of  the  Company  with  or  into  another
corporation,  or  any  conveyance of all or substantially all of the assets of
the  Company,  or  voluntary  or involuntary dissolution or liquidation of the
Company  shall be effected, then, in any such case, the Company shall cause to
be mailed to the Holder, at least thirty (30) days prior to the date specified
in  (x)  or  (y)  below,  as  the  case  may  be,  a notice containing a brief
description  of the proposed action and stating the date on which (x) a record
is  to  be  taken for the purpose of such dividend, distribution or rights, or
(y)  such reclassification, reorganization, consolidation, merger, conveyance,
dissolution  or  liquidation  is  to  take place and the date, if any is to be
fixed,  as of which the holders of Common Stock of record shall be entitled to
exchange  their  shares  of  Common  Stock  for  securities  or other property
deliverable upon such reclassification, reorganization, consolidation, merger,
conveyance,  dissolution  or  liquidation.

     9.     Certain Obligations of the Company.  The  Company  agrees  that it
            ----------------------------------
will  not  increase the par value of the shares of Warrant Stock issuable upon
exercise  of  this  Warrant  above  the  prevailing  and  currently applicable
Exercise  Price  hereunder, and that before taking any action that would cause
an  adjustment  reducing  the prevailing and current applicable Exercise Price
hereunder  below  the then par value of the Warrant Stock at the time issuable
upon exercise of this Warrant, the Company will take such corporate action, as
in  the opinion of its counsel, may be necessary in order that the Company may
validly  issue  fully  paid,  nonassessable shares of such Warrant Stock.  The
Company  will  maintain  an  office  or  agency  (which shall initially be the
Company's  principal  office  in Redwood City, California) where presentations
and  demands to or upon the Company in respect of this Warrant may be made and
will  give notice in writing to the registered holders of the then outstanding
Warrants,  at  their  addresses  as shown on the books of the Company, of each
change  of  location  thereof.

     10.    Repurchase Right.  Notwithstanding  any  other  provisions of this
            ----------------
Warrant,  the  Company may, in the event that the average trading price of the
Company's  Common  Stock,  as  reported  on the NASDAQ SmallCap Market or such
other exchange on which the Company's Common Stock may then be quoted, exceeds
$10.00  for  a  period  of twenty (20) consecutive trading days, upon not less
than  thirty (30) days' notice in writing to the Holder, repurchase all or any
portion  of this Warrant at a purchase price equal to $.10 per share of Common
Stock  covered  hereby, such purchase price to be proportionally adjusted each
time the Exercise Price is adjusted pursuant to Section 6 hereof.  During such
thirty  (30)  day  period, the Holder may exercise such Warrants in accordance
with the terms hereof.  The closing on such repurchase shall occur on the date
