                                   (UNAUDITED)



NOTE  A  -  ORGANIZATION

     Penn  Octane  Corporation,   formerly   International   Energy  Development
     Corporation  (IEDC)  and The  Russian  Fund,  a Delaware  corporation,  was
     incorporated  on August 27, 1992.  On October 21, 1993,  IEDC acquired Penn
     Octane Corporation,  a Texas corporation,  whose primary asset was a liquid
     petroleum gas (LPG) pipeline lease agreement (Pipeline Lease) with Seadrift
     Pipeline Corporation (Seadrift),  a subsidiary of Union Carbide Corporation
     (Union  Carbide).  On January 6, 1995, the Board of Directors  approved the
     change of IEDC's  name to Penn Octane  Corporation.  The Company is engaged
     primarily in the business of purchasing,  transporting  and selling LPG and
     has provided  services and equipment to the  compressed  natural gas ( CNG)
     industry.  Substantially  all of the LPG sales volume since  inception  has
     been to PMI Trading  Limited  (PMI),  a subsidiary  of Petroleos  Mexicanos
     (PEMEX), the Mexican state owned oil company.

     In February  1997,  the Company formed Wilson  Acquisition  Corporation,  a
     Delaware  corporation  and a  wholly-owned  subsidiary,  for the purpose of
     engaging  in  the  business  of  designing,  constructing,  installing  and
     servicing  equipment for CNG fueling  stations and related products for use
     in the CNG industry throughout the world. The subsidiary's name was changed
     to PennWilson CNG, Inc. (PennWilson) in August 1997.

     In October 1997, the Company formed Penn CNG Holdings,  Inc. (Holdings),  a
     Delaware corporation and a wholly-owned  subsidiary.  In February 1998, the
     Company formed PennWill,  S.A. de C.V., Camiones Ecologicos,  S.A. de C.V.,
     Grupo Ecologico Industrial, S.A. de C.V., Estacion Ambiental, S.A. de C.V.,
     Estacion Ambiental II, S.A. de C.V., and Serinc, S.A. de C.V. (collectively
     Estacion), all Mexican corporations. To date there has not been significant
     operations for any of these entities.

     BASIS  OF  PRESENTATION
     -----------------------

     The  accompanying   financial   statements  include  the  Company  and  its
     subsidiaries,   PennWilson   and  Holdings   (Company).   All   significant
     intercompany accounts and transactions are eliminated.

     The  unaudited  consolidated  balance  sheet as of October  31,  1998,  the
     unaudited  consolidated   statements  of  operations,   and  the  unaudited
     consolidated  statements  of cash flows for the three months ended  October
     31, 1998 and 1997 have been prepared by the Company  without audit.  In the
     opinion of management,  the financial  statements  include all  adjustments
     (which  include  only normal  recurring  adjustments)  necessary to present
     fairly the unaudited  consolidated  financial position of the Company as of
     October 31, 1998 and the unaudited  consolidated  results of operations and
     unaudited  consolidated  cash flows for the three months ended  October 31,
     1998 and 1997.

     Certain information and footnote disclosures normally included in financial
     statements  prepared  in  accordance  with  generally  accepted  accounting
     principles have been omitted.  These financial statements should be read in
     conjunction with the financial statements and notes thereto included in the
     Company's Annual Report on Form 10-K for the year ended July 31, 1998.

     Certain  reclassifications  have  been  made to prior  period  balances  to
     conform  to the  current  presentation.  All  reclassifications  have  been
     applied consistently to the periods presented.

     NOTE B - (LOSS) PER COMMON SHARE

     (Loss) per share of common stock is computed on the weighted average number
     of shares outstanding. During periods in which the Company incurred losses,
     giving effect to common stock  equivalents  is not presented as it would be
     antidilutive.

     The FASB issued Statement of Financial  Accounting  Standards No. 128 (SFAS
     128),  "Earnings Per Share", which supersedes  Accounting  Principles Board
     Opinion  No.  15 (APB 15),  "Earnings  Per  Share".  The  statement  became
     effective for financial statements issued for periods ending after December
     15, 1997, including interim periods. Early adoption was not permitted.

     The following table presents  reconciliations  from (loss) per common share
     to (loss) per common share  assuming  dilution (see note G for the warrants
     and convertible preferred stock excluded because they are anti-dilutive):

     NOTE E - NYDOT CNG FUELING STATION

     During  the year ended  July 31,  1998,  the  Company  recorded  additional
     revenues of approximately  $821,994 related to change-orders for additional
     work  performed  by the  Company in  connection  with the  construction  of
     equipment  for a CNG fueling  station for the New York City  Department  of
     Transportation  (NYDOT).  The  change-orders  have  been  submitted  to the
     customer  for  approval.  During March 1998,  the Company was  requested to
     furnish   additional   documentation   with   respect   to  the   submitted
     change-orders which was subsequently provided on May 15, 1998. On April 30,
     1998, the Company received  notification from the general contractor,  A.E.
     Schmidt  Environment  ("AES"),  that the Company  was in default  under the
     agreement  between  AES and the  Company  relating to the NYDOT CNG fueling
     station. The Company has responded to AES indicating that AES is in default
     with  the  terms  of  the  agreement  and  that  the  Company  is  awaiting
     satisfactory  resolution  of  these  matters  prior  to  completion  of the
     remaining  work  outlined  under the  agreement.  The Company is  currently
     exploring  legal  remedies  available.  As of July 31,  1998,  the  Company
     revised its estimate  related to the work preformed in connection  with the
     change-orders.  As a result of this revision the Company  reduced  revenues
     associated with the change-orders by $500,000 and recorded an allowance for
     doubtful  accounts of  $321,994.  In  connection  with this  contract,  the
     Company  does  not  anticipate  a  material  amount  of  additional   costs
     associated with either completion of the contract or subsequent  warranties
     provided for in the contract.

     For the three  months  ended  October 31,  1997,  the Company had  recorded
     additional  revenues of approximately  $600,000 related to change-orders in
     connection with the NYDOT CNG fueling station.

NOTE  G  -  STOCKHOLDERS'  EQUITY

     PREFERRED  STOCK
     ----------------

     On September 18, 1993, in a private  placement,  the Company issued 150,000
     shares  of its $.01  par  value,  11%  convertible,  cumulative  non-voting
     preferred  stock at a purchase price of $10.00 per share.  On June 10, 1994
     the  Company  declared  a 2-for-1  stock  split.  The  preferred  stock was
     convertible  into  voting  shares  of  common  stock  of the  Company  at a
     conversion ratio of one share of preferred stock for 3.333 shares of common
     stock.  On  September  10,  1997,  the Board of  Directors  of the  Company
     approved the issuance of an additional 100,000 shares of common stock as an
     inducement  for  the  preferred  stockholders  to  convert  the  shares  of
     preferred stock and release all rights with respect to the preferred stock.
     In January 1998, all 270,000  shares of the preferred  stock were converted
     into an  aggregate of 999,910  shares of common  stock of the Company.  The
     issuance  of  the  additional  100,000  common  shares  was  recorded  as a
     preferred stock dividend in the amount of $225,000 at January 30, 1998.

     STOCK  AWARD  PLAN
     ------------------

     Under the  Company's  1997 Stock Award Plan,  the Company has  reserved for
     issuance  150,000  shares of Common  Stock,  of which  129,686  shares were
     unissued  as of  October  31,  1998,  to  compensate  consultants  who have
     rendered  significant  services to the Company. The Plan is administered by
     the  Compensation  Committee of the Board of Directors of the Company which
     has complete  authority  to select  participants,  determine  the awards of
     Common  Stock to be granted  and the times  such  awards  will be  granted,
     interpret  and  construe  the 1997  Stock  Award Plan for  purposes  of its
     administration  and make  determinations  relating  to the 1997 Stock Award
     Plan,  subject to its  provisions,  which are in the best  interests of the
     Company  and  its   stockholders.   Only   consultants  who  have  rendered
     significant   advisory   services  to  the  Company  are   eligible  to  be
     participants under the Plan. Other eligibility  criteria may be established
     by the Compensation Committee as administrator of the Plan.

     In October  1997,  the Company  issued  20,314  shares of Common Stock to a
     Mexican  consultant in payment for services  rendered to the Company valued
     at $113,000 pursuant to the plan.

NOTE  H  -  COMMITMENTS  AND  CONTINGENCIES

     LITIGATION

     On August 24, 1994, the Company filed an Original  Petition and Application
     for    Injunctive    Relief    against    the    International    Bank   of
     Commerce-Brownsville    ("IBC-Brownsville"),    a   Texas   state   banking
     association,  seeking (i) either  enforcement of a credit facility  between
     the  Company and  IBC-Brownsville  or a release of the  Company's  property
     granted as collateral  thereunder  consisting of  significantly  all of the
     Company's business and assets;  (ii) declaratory relief with respect to the
     credit facility;  and (iii) an award for damages and attorneys' fees. After
     completion of an  arbitration  proceeding,  on February 28, 1996, the 197th
     District  Court in and for Cameron  County,  Texas  entered  judgment  (the
     "Judgment")  confirming the arbitral award for $3,246,754 to the Company by
     IBC-Brownsville.

     In connection  with the lawsuit,  IBC-Brownsville  filed an appeal with the
     Texas  Court of Appeals on January  21,  1997.  The  Company  responded  on
     February 14, 1997. On September 18, 1997, the appeal was heard by the Texas
     Court of Appeals and on June 18,  1998,  the Texas Court of Appeals  issued
     its  opinion  in the  case,  ruling  essentially  in favor of the  Company.
     IBC-Brownsville sought a rehearing of the case on August 3, 1998. The Court
     has not ruled on the IBC-Brownsville  request for rehearing.  A decision is
     expected by December  31, 1998.  As of October 31, 1998,  the net amount of
     the award is  approximately  $3.5  million,  which is  comprised of (i) the
     original  judgment,  including  attorneys' fees, (ii) post-award  interest,
     (iii)   cancellation   of  the  note  and  accrued   interest   payable  to
     IBC-Brownsville which is included in the Consolidated Financial Statements,
     less attorneys' fees.

     On April 18, 1996, the Company  reached an agreement  (the "IBC  Settlement
     Agreement") to accept $400,000 to settle a lawsuit it filed in October 1995
     against  International  Bank of  Commerce-San  Antonio,  a bank  related to
     IBC-Brownsville  ("IBC-San Antonio").  As part of the settlement agreement,
     the parties, including IBC-Brownsville and IBC-San Antonio, executed mutual
     releases  from future  claims  related to the  IBC-Brownsville  litigation.
     Additionally,  IBC-San Antonio agreed to indemnify the Company for any such
     claims made or asserted.

     On June 26, 1996,  IBC-Brownsville  filed a suit against the Company  (Case
     No.  96-06-3502)  in the 357th  Judicial  District  Court of Cameron County
     alleging that the Company,  in filing the Judgment against  IBC-Brownsville
     in  order  to  clear   title  to  its   assets,   slandered   the  name  of
     IBC-Brownsville.  IBC-Brownsville  contends  that the  Judgment  against it
     prevented it from selling  certain  property.  IBC-Brownsville  has claimed
     actual damages of $600,000 and requested punitive damages of $2,400,000. On
     September 23, 1996, the court entered the Judgment on behalf of the Company
     indicated in a preliminary ruling that the Company was privileged in filing
     the Judgment to clear title to its assets.

     On July 30, 1996,  the Company  filed suit in the District  Court of Harris
     County,  Texas against Jorge V. Duran,  former Chairman of the Board of the
     Company,  regarding  alleged  conversion  and fraud by Mr. Duran during his
     time as an employee of the Company.  The Company has not yet quantified its
     damages and is seeking a declaration  that the termination of employment of
     Mr.  Duran was lawful and  within  the rights of the  Company  based on Mr.
     Duran's status as an at-will employee of the Company. On December 12, 1996,
     Mr.  Duran filed a  counterclaim  in the District  Court of Harris  County,
     Texas  asserting  the  following  claims:  breach of  contract  against the
     Company  and Mr.  Richter;  wrongful  discharge  against the  Company,  Mr.
     Richter,  and Mr.  Mark  Casaday,  a former  officer  and  director  of the
     Company; defamation against the Company, Mr. Richter, Mr. Mark Casaday, and
     Mr. Jorge  Bracamontes;  and  interference  with contract against Mr. Jorge
     Bracamontes.  On February 27, 1997, the two actions were  consolidated into
     Case No. 96-37447,  Penn Octane  Corporation v. Jorge V. Duran in the 164th
     District Court of Harris County, Texas and on September 30, 1998, Mr. Duran
     filed a Fourth Amended  Original  Petition.  Mr. Duran is seeking  judgment
     against  the  Company and Messrs.  Richter,  Casaday  and  Bracamontes  for
     damages  in excess of $12.0  million,  including  prejudgment  interest  as
     provided

     for by law, and attorneys'  fees and such further relief to which he may be
     justly  entitled.  The Company  intends to  vigorously  defend  against Mr.
     Duran's counterclaim.

     On October 14,  1998,  a  complaint  was filed by Amwest  Surety  Insurance
     Company ("Amwest") naming as defendants,  among others,  PennWilson and the
     Company  seeking  reimbursement  for  payments  made  by  Amwest  from  the
     performance  and payment bonds in response to claims for services  provided
     by suppliers,  laborers and other  materials and work to complete the NYDOT
     contract.  The  Company is  currently  considering  its legal  options  and
     intends to file an answer to Amwest's complaint.

     The Company and its subsidiaries are also involved with other  proceedings,
     lawsuits and claims. The Company is of the opinion that the liabilities, if
     any, ultimately resulting from such proceedings, lawsuits and claims should
     not materially affect its consolidated financial position.

     CREDIT FACILITY, LETTERS OF CREDIT AND OTHER

     In connection with the PMI Sales Agreement,  invoicing occurs weekly.  From
     November  1996  to  early  November  1997,  the  Company  and  PMI  made an
     arrangement  under which PMI  provided  financing on the  Company's  behalf
     under the terms of the Company's supply agreement with Exxon, the Company's
     main supplier.  As a result of this  arrangement,  invoicing  occurred on a
     monthly, rather than a weekly basis.

     On October 22, 1997, the Company entered into a $6,000,000  credit facility
     with RZB  Finance  L.L.C.  (RZB) for demand  loans and  standby  letters of
     credit (RZB Credit  Facility) to finance the Company's  purchase of LPG and
     propylene (PPL). Under the RZB Credit Facility, the Company pays a fee with
     respect  to each  letter of  credit  thereunder  in an amount  equal to the
     greater of (i) $500, (ii) 1.5% of the maximum face amount of such letter of
     credit,  or (iii) such higher  amount as may be agreed  between the Company
     and RZB. Any amounts outstanding under the RZB Credit Facility shall accrue
     interest at a rate equal to the rate announced by the Chase  Manhattan Bank
     as its prime rate plus 2.5%.  Pursuant to the RZB Credit Facility,  RZB has
     sole and absolute  discretion to terminate  the RZB Credit  Facility and to
     make any loan or issue any  letter of credit  thereunder.  RZB also has the
     right to demand  payment of any and all amounts  outstanding  under the RZB
     Credit  Facility at any time. In connection  with the RZB Credit  Facility,
     the Company granted a mortgage, security interest and assignment in any and
     all of the Company's  real  property,  buildings,  pipelines,  fixtures and
     interests therein or relating thereto,  including,  without limitation, the
     lease with the  Brownsville  Navigation  District of Cameron County for the
     land on which the Company's  Brownsville  Terminal Facility is located, the
     Pipeline Lease, and in connection therewith entered into leasehold deeds of
     trust,  security agreements,  financing statements and assignments of rent.
     Under the RZB  Credit  Facility,  the  Company  may not permit to exist any
     lien,  security  interest,  mortgage,  charge or other  encumbrance  of any
     nature on any of its properties or assets,  except in favor of RZB, without
     the consent of RZB. The Company's  President,  Chairman and Chief Executive
     Officer has personally  guaranteed all of the Company's payment obligations
     with  respect to the RZB Credit  Facility.  Upon  establishment  of the RZB
     Credit  Facility,  beginning  November 11, 1997, PMI no longer provided any
     financing on behalf of the Company,  and the Company began invoicing PMI on
     a weekly basis.

     Effective  April 22, 1998,  the aggregate  amount  available  under the RZB
     Credit Facility was increased to $7,000,000.

     In connection  with the  Company's  purchases of LPG from Exxon and/or PG&E
     NGL  Marketing,  L.P.,  the Company  issues  letters of credit on a monthly
     basis based on anticipated purchases.

     As of October 31, 1998,  letters of credit established under the RZB Credit
     Facility in favor of Exxon for purchases of LPG totaled $6,000,000 of which
     $1,204,502  was being  used to secure  unpaid  purchases  from  Exxon as of

     connection  with these  purchases,  as of October 31, 1998, the Company had
     unpaid  invoices  due  from  PMI  totaling  $1,828,631  and  cash  balances
     maintained in the RZB Credit Facility collateral account of $779.

     During June 1998, a letter of credit was  established  under the RZB Credit
     Facility in favor of PG&E NGL Marketing, L.P. for purchases of LPG totaling
     $360,000. The letter of credit expired in August 1998.

     During  November  1998,  a letter of credit was  established  under the RZB
     Credit  Facility in favor of PG&E NGL Marketing,  L.P. for purchases of LPG
     totaling $176,000.

NOTE  I  -  REALIZATION  OF  ASSETS

     The accompanying financial statements have been prepared in conformity with
     generally accepted accounting principles, which contemplate continuation of
     the  Company as a going  concern.  The Company has  incurred  losses  since
     inception,  has used cash in operations,  has a deficit in working  capital
     and  stockholders'  equity and is  delinquent  under certain loan and lease
     agreements. In addition, the Company is involved in litigation, the outcome
     of which cannot be  determined at the present time. As discussed in note A,
     the  Company  has  historically  depended  heavily  on sales  to one  major
     customer.

     In view of the matters described in the preceding paragraph, recoverability
     of a  major  portion  of  the  recorded  asset  amounts  as  shown  in  the
     accompanying consolidated balance sheet is dependent upon the collection of
     the Judgment,  the Company's ability to obtain additional  financing and to
     raise  additional  equity capital,  and the success of the Company's future
     operations. The financial statements do not include any adjustments related
     to the  recoverability  and  classification  of recorded  asset  amounts or
     amounts and  classification  of liabilities  that might be necessary should
     the Company be unable to continue in existence.

     To provide the Company  with the ability it believes  necessary to continue
     in existence,  management  is taking steps to 1) collect the  Judgment,  2)
     increase sales to its current customers,  3) increase its customer base, 4)
     extend the terms and  capacity of the  Pipeline  Lease and the  Brownsville
     Terminal Facility, 5) expand its product lines and 6) raise additional debt
     and/or equity capital.

     At July 31, 1998,  the Company had net  operating  loss  carryforwards  for
     federal  income tax purposes of  approximately  $8,826,000.  The ability to
     utilize such net operating loss carryforwards may be significantly  limited
     by the application of the "change of ownership"  rules under Section 382 of
     the Internal Revenue Code.

NOTE  J  -  CONTRACTS

     LPG  BUSINESS

     The Company has entered into a sales agreement  (Agreement)  with its major
     customer,  PMI, to provide a minimum  monthly  volume of LPG to PMI through
     September 30, 1999.  During October 1998, the Company was purchasing LPG on
     a  month-to-month  basis  from Exxon  Company,  U.S.A.  (Exxon),  its major
     supplier,  to meet the minimum monthly  volumes  required in the Agreement.
     Effective November 1, 1998, the Company entered into a supply contract with
     Exxon to purchase  minimum  monthly  volumes of LPG through  September 1999
     under payment terms similar to those required in the Agreement.  The supply
     price is below the sales price provided for in the Agreement.

     CNG BUSINESS

     The Company has not entered into any CNG  contracts  subsequent to July 31,
     1998.

NOTE  K  -  SEGMENT  INFORMATION

     The FASB issued Statement of Financial  Accounting  Standards No. 131 (SFAS
     No.  131),   "Disclosure  about  Segments  of  an  Enterprise  and  Related
     Information",  effective for years  beginning after December 15, 1997, with
     earlier application encouraged. The Company adopted SFAS 131 in 1997.

     The Company has the  following  reportable  segments:  LPG and CNG. The LPG
     segment is a distributor of fuel and the CNG segment designed,  constructed
     and installed  fueling  stations  since its  inception  through early 1998.
     Subsequently,  the CNG segment focused  primarily on the  construction  and
     operation  of a CNG vehicle and fueling  station  infrastructure  in Mexico
     City, Mexico.

     The accounting policies used to develop segment  information  correspond to
     those described in the summary of significant accounting policies.  Segment
     profit (loss) is based on profit (loss) from operations  before income tax.
     The reportable  segments are distinct  business units  operating in similar
     industries.  They are  separately  managed,  with  separate  marketing  and
     distribution  systems. The following  information about the segments is for
     the three months ended October 31, 1998 and 1997.

     the Company and warrants to purchase  75,000 shares of common stock with an
     exercise price of $1.25 per warrant and an expiration  date of November 12,
     2000 for an amount of $250,000.  Net  proceeds  from the sale were used for
     working capital purposes.

     On December 14, 1998,  the Company issued 500,000 shares of common stock of
     the Company and warrants to purchase 300,000 shares of common stock with an
     exercise price of $1.75 per warrant and an expiration  date of December 13,
     2003 for an amount of $500,000. Net proceeds from the sale will be used for

     PROMISSORY  NOTE  AMENDMENT
     ---------------------------

     On October 21, 1997, the Company completed a private placement  pursuant to
     which it issued promissory notes in the aggregate  principal amount of $1.5
     million and warrants to purchase 250,000 shares of common stock exercisable
     until October 21, 2000 at an exercise  price of $6.00 per share.  The notes
     were  unsecured.  Proceeds raised from the private  placement  totaled $1.5
     million, which the Company used for working capital requirements.  Interest
     at 10% per annum was due  quarterly on March 31, June 30,  September 30 and

     completed a rollover and assignment agreement effectively extending the due
     date  of  the   promissory   notes  until  June  30,  1999  (the  "Rollover
     Agreement").  In connection with the Rollover Agreement, the Company agreed
     to assign its rights to any net cash  collected  from the Judgment  towards
     any unpaid  principal  and  interest  owing on the  promissory  notes.  The
     Company  also agreed to use any net  proceeds  received by the Company from

     $2,250,000,   towards  the  repayment  of  any  balances  owing  under  the
     promissory  notes.  The  promissory  note holders also received  additional
     warrants to purchase  337,500  shares of common  stock,  exercisable  until
     November 30, 2001, at an exercise price of $1.75 per share.  The purchasers
     in the private  placement were granted one demand  registration  right with

ITEM  2.     MANAGEMENT'S  DISCUSSION  AND  ANALYSIS  OF FINANCIAL CONDITION AND
             RESULTS  OF  OPERATIONS

     The  following  discussion  of  the  Company's  results  of  operations and
liquidity  and  capital  resources  should  be  read  in  conjunction  with  the
Consolidated  Financial  Statements  of  the  Company  and related Notes thereto
appearing  elsewhere  herein.  References to specific years preceded by "fiscal"
(e.g.  fiscal  1999)  refer  to  the  Company's  fiscal year ended July 31.  The
results  of  operations of PennWilson, which began operations in March 1997 have
been  included  in  the Company's results of operations for fiscal 1999 and 1998
discussed  below.  To  date,  there  has been no significant activity associated
with  the  operations  of  Holdings  or  Estacion.

OVERVIEW

     The  Company  has  been principally engaged in the purchase, transportation
and  sale of LPG and, since 1997, the provision of equipment and services to the
CNG  industry.  Beginning  July  1994,  the  Company has bought and sold LPG for
distribution  into  northeast  Mexico  and  the  U.S.  Rio  Grande  Valley.

     Historically,  the  Company  has  derived substantially all of its revenues
from sales to PMI, its primary customer, of LPG purchased from Exxon.  In fiscal
1998,  the  Company derived approximately 95% of its revenues from sales of LPG,
of  which  sales  to  PMI  accounted  for  nearly  100%  of  total  LPG  sales.

     As  part  of  its  business  strategy,  in  March 1997 the Company acquired
certain assets and hired certain former employees from WTI, a company engaged in
the  engineering,  design  and construction of equipment for turnkey CNG fueling
stations.  In  connection  with  this acquisition, the Company paid $394,000 and
was  committed  to  pay  up  to $2.0 million in royalty payments based on future
sales,  if  any.  The  acquisition  was accounted for as a purchase and has been
reflected  as  such in the Company's consolidated financial statements beginning
in  fiscal  1997.

     The  Company's  CNG revenues were previously derived from contracts awarded
on  a  fixed-price,  as-completed  basis.  Currently,  the  Company is no longer
actively  pursuing  contracts  to  construct  CNG  equipment  for  sale to third
parties.  Due  to  the  current  financial  condition  of  the  Company  and the
additional  capital  required to pursue CNG operations in Mexico, the Company is
currently  reassessing  its  CNG  business  strategy  including  the  possible
disposition  of some or all of the Company's CNG assets.  As of the date of this
Report, the Board has not definitively determined whether to continue or dispose
of  the  Company's  CNG  business.

     The  Company  provides  products  and  services  through  a  combination of
fixed-margin and fixed-price contracts.  Under the Company's agreements with its
customers  and  suppliers,  the  buying  and  selling prices of LPG are based on
variable  posted  prices  that  provide  the Company with a fixed margin.  Costs
included  in costs of goods sold other than the purchase price of LPG may affect
actual  profits from sales, including costs relating to transportation, storage,
leases,  maintenance  and financing.  The Company generally attempts to purchase
in volumes commensurate with projected sales. However, mismatches in volumes and
prices  of  LPG  purchased  from  Exxon  and  resold  to  PMI  could  result  in
unanticipated  costs.

RESULTS  OF  OPERATIONS

     THREE  MONTHS  ENDED  OCTOBER  31,  1998,  COMPARED  THE THREE MONTHS ENDED
OCTOBER  31,  1997

     Revenues.  Revenues  for  the three months ended October 31, 1998 were $6.5
million  compared with $8.2 million for the three months ended October 31, 1997,
a  decrease  of  $1.7  million  or 20.7%.  Of this decrease (i) $1.6 million was
attributable to revenues from sales of equipment for CNG fueling stations due to
the  Company's  decision  to  reassess its CNG business strategy resulting in $0
revenues  from  CNG  related contracts during the three months ended October 31,
1998  and  (ii) $124,282 related to the Company's LPG business; $2.2 million was
attributable  to  a  decrease  in  average  sales price for LPG during the three
months ended October 31, 1998, partially offset by increased volumes of LPG sold
during  the  three  months  ended  October 31, 1998, resulting in an increase in
sales  of  $2.1  million.

     Cost  of  sales.  Cost of sales for the three months ended October 31, 1998
was  $5.9  million compared with $7.8 million for the three months ended October
31,  1997,  a  decrease  of  $1.9  million  or 24.4%.  Of this decrease (i) $1.5
million  was  attributable  to  costs associated with sales of equipment for CNG
fueling  stations  as described above and (ii) $411,306 of costs associated with
the  Company's  LPG  business  ($2.2  million  was attributable to a decrease in
average  purchase  price for LPG purchased during the three months ended October
31,  1998,  offset by the increase in volume of LPG sold during the three months
ended  October  31, 1998, resulting in an increase in cost of goods sold of $1.8
million).

     Selling,  general  and  administrative  expenses.  Selling,  general  and
administrative  expenses  were  $662,039  for the three months ended October 31,
1998  compared  with  $550,362  for  the three months ended October 31, 1997, an
increase  of  $111,677  or  20.3%.  This  increase was primarily attributable to
payroll  and  other related costs in connection with the Company's LPG business,
partially  offset  by  reductions in costs associated with the operations of the
CNG  business  for  the  three  months  ended  October  31,  1998.

     Other  income and expenses, net.  Other income (expense), net was ($96,850)
for the three months ended October 31, 1998 compared with ($3,629) for the three
months  ended  October  31,  1997.  The increase in other income (expense), net,
during  the  three  months  ended October 31, 1998 was due primarily to interest
income  on  a  note  from the president of the Company and a related party which
during  fiscal  1999,  will  be  recorded  only  when cash is actually received.

     Income  tax.  Due  to the net losses for the three months ended October 31,
1998  and  1997,  there was no income tax expense in either period.  At July 31,
1998,  the  Company  had net operating loss carryforwards for federal income tax
purposes  of  approximately  $8.8  million.  The  ability  to  utilize  such net
operating  loss  carryforwards,  which  expire in the years 2009 to 2013, may be
significantly  limited  by  the  application  of the "change of ownership" rules
under  Section  382  of  the  Internal  Revenue  Code.

     Historically,  the  Company  has  received the majority of its total annual
revenues  during  the  months  of  October  through  March.  Such  pattern  is
attributable  to the seasonal demand for LPG, which is typically greatest during

                                       21
<PAGE>
the winter months of the second and third quarters of the Company's fiscal year.
The Company's quarterly earnings may vary considerably due to the impact of such
seasonality.

LIQUIDITY  AND  CAPITAL  RESOURCES

     General.  The Company has had an accumulated deficit since its inception in
1992,  has  used  cash  in  operations  and has a deficit in working capital and
stockholders'  equity.  In  addition, the Company is involved in litigation, the
outcome  of which cannot be determined at the present time.  The Company depends
heavily  on sales to one major customer.  The Company's sources of liquidity and
capital  resources  historically  have  been  provided  by  sales  of  LPG  and
CNG-related  equipment,  proceeds  from the issuance of short-term and long-term
debt,  revolving  credit facilities and credit arrangements, sale or issuance of
preferred  and  common  stock  of  the Company and proceeds from the exercise of
warrants  to  purchase  shares  of  the  Company's  common  stock.

     The  following  summary table reflects comparative cash flows for the three
months  ended  October  31,  1998  and  1997.  All  information is in thousands.

     The  PMI  Sales  Agreement is effective for the period from October 1, 1998
through  September  30,  1999  and  provides  for the purchase by PMI of minimum
monthly  volumes  of  LPG  aggregating  a  minimum annual volume of 69.0 million
gallons,  similar  to  minimum  volume  requirements  under  the  previous sales
agreement with PMI effective during the period from October 1, 1997 to September
30,  1998.  During  October  1998,  the  Company  entered  into a monthly supply
agreement with Exxon pursuant to which Exxon agreed to supply minimum volumes of
LPG  to  the  Company.  Effective  November  1, 1998, the Company entered into a
supply  agreement  with Exxon to purchase minimum monthly volumes of LPG through
September 1999.  The Company believes it has access to an adequate supply of LPG
from  Exxon and other suppliers to satisfy the requirements of PMI under the PMI
Sales  Agreement.  In  determining  whether  any  supplier will be utilized, the
Company  will  consider  the applicable prices charged as well as any additional
fees  that  may  be  required  to be paid under the Pipeline Lease.  The Company
anticipates  10%  -  15%  lower  gross  margins  on its LPG sales as a result of
increased  LPG  costs  beginning  October  1998  compared  with  the  previous
agreements.

                                       22

     Pipeline  Lease.  The  Pipeline  Lease currently expires on March 31, 2013,
pursuant  to  an  amendment entered into between the Company and Seadrift on May
21,  1997,  effective  on  April  1, 1998 (the "Pipeline Lease Amendment").  The
Pipeline  Lease  Amendment  provides, among other things, for additional storage
access  and  inter-connection  with  another  pipeline  controlled  by Seadrift,
thereby  providing  greater  access  to  and from the Pipeline.  Pursuant to the
Pipeline Lease Amendment, the Company's fixed annual fee associated with the use
of  the  Pipeline  was  increased  by  $350,000. In addition, the Pipeline Lease
Amendment  also  provides for variable rental increases based on monthly volumes
purchased  and  flowing into the Pipeline.  As of October 31, 1998, Seadrift had
yet  to  make  certain improvements which the Company believes were the basis of
the  increase  in  rent  required  under  the  Pipeline  Lease Amendment ("Basic
Improvements").  Accordingly, Seadrift has continued to invoice the Company, and
the Company has continued to make lease payments to Seadrift as prescribed under
the  Pipeline Lease.  The Company further believes that the term of the Pipeline
Lease Amendment shall commence upon the completion of the Basic Improvements and
terminate  fifteen  years thereafter.  The Company believes the extension of the
Pipeline  Lease gives the Company increased flexibility in negotiating sales and
supply  agreements  with its customers and suppliers.  During November 1998, the
Company  issued  a  promissory  note  to Seadrift for $261,206, representing all
outstanding  rental  obligations  owed  to  Seadrift through November 1998.  The
promisorry  note  is payable in six installments beginning November 25, 1998 and
ending  February  3,  1999.  Interest  on  the promissory note is 10% per annum.

     Credit Arrangements.  In connection with the PMI Sales Agreement, invoicing
is  to occur weekly.  From November 1996 to early November 1997, the Company and
PMI  made  an  arrangement  under  which PMI provided financing on the Company's
behalf  under  the  terms  of  the  Company's  supply  agreement with Exxon, the
Company's main supplier.  As a result of this arrangement, invoicing occurred on
a  monthly,  rather  than  a  weekly  basis.

     On  October  22,  1997,  the  Company  entered  into  a $6.0 million credit
facility  with  RZB Finance L.L.C. (RZB) for demand loans and standby letters of
credit  (RZB  Credit  Facility) to finance the Company's purchase of LPG.  Under
the  RZB  Credit Facility, the Company pays a fee with respect to each letter of
credit  thereunder  in  an amount equal to the greater of (i) $500, (ii) 1.5% of
the maximum face amount of such letter of credit, or (iii) such higher amount as
may be agreed to between the Company and RZB.  Any amounts outstanding under the
RZB  Credit Facility shall accrue interest at a rate equal to the rate announced
by  the  Chase  Manhattan Bank as its prime rate plus 2.5%.  Pursuant to the RZB
Credit  Facility,  RZB  has  sole  and  absolute discretion to terminate the RZB
Credit  Facility  and to make any loan or issue any letter of credit thereunder.
RZB  also  has  the  right  to demand payment of any and all amounts outstanding
under  the  RZB  Credit Facility at any time.  In connection with the RZB Credit
Facility,  the  Company  granted a mortgage, security interest and assignment in
any  and  all of the Company's real property, buildings, pipelines, fixtures and
interests  therein or relating thereto, including, without limitation, the lease
with the Brownsville Navigation District of Cameron County for the land on which
the  Company's Brownsville Terminal Facility is located, the Pipeline Lease, and
in  connection therewith agreed to enter into leasehold deeds of trust, security
agreements,  financing statements and assignments of rent, in forms satisfactory
to  RZB.  Under the RZB Credit Facility, the Company may not permit to exist any
lien,  security interest, mortgage, charge or other encumbrance of any nature on
any  of its properties or assets, except in favor of RZB, without the consent of
RZB.  The  Company's  President,  Chairman  and  Chief  Executive  Officer  has
personally  guaranteed  all of the Company's payment obligations with respect to
the  RZB  Credit  Facility.  Upon  establishment  of  the  RZB  Credit Facility,
beginning  November  11, 1997, PMI no longer provided any financing on behalf of
the  Company,  and  the  Company  began  invoicing  PMI  on  a  weekly  basis.

                                       23
<PAGE>
     Effective  April  22,  1998,  the  aggregate amount available under the RZB
Credit  Facility was increased to $7.0 million.  The Company believes that based
on  current market prices of LPG and LPG volume requirements under the PMI Sales
Agreement,  the  RZB  Credit  Facility  is  adequate.

     In  connection  with  the Company's purchases of LPG from Exxon and/or PG&E
NGL  Marketing,  L.P.,  the  Company issues letters of credit on a monthly basis
based  on  anticipated  purchases.

               As  of  October 31, 1998, letters of credit established under the
RZB  Credit Facility in favor of Exxon for purchases of LPG totaled $6.0 million
of which $1.2 million was being used to secure unpaid purchases from Exxon as of
October  31,  1998.  In  addition,  as of October 31, 1998, the Company had $1.4
million  of loans outstanding under the RZB Credit Facility.  In connection with
these  purchases,  as  of  October 31, 1998, the Company had unpaid invoices due
from  PMI  totaling  $1.8 million and cash balances maintained in the RZB Credit
Facility  collateral  account  of  $779.

     During  June  1998, a letter of credit was established under the RZB Credit
Facility  in  favor  of  PG&E  NGL Marketing, L.P. for purchases of LPG totaling
$360,000.  The  letter  of  credit  expired  during  August  1998.

     During  November  1998,  a  letter  of credit was established under the RZB
Credit  Facility  in  favor  of  PG&E  NGL  Marketing, L.P. for purchases of LPG
totaling  $176,000.

     Private  Placements  and  Other  Transactions.     On October 21, 1997, the
Company  completed  a  private  placement pursuant to which it issued promissory
notes in the aggregate principal amount of $1.5 million and warrants to purchase
250,000 shares of common stock exercisable until October 21, 2000 at an exercise
price  of  $6.00 per share.  The notes were unsecured.  Proceeds raised from the
private  placement  totaled  $1.5  million,  which  the Company used for working
capital  requirements.  Interest at 10% per annum was due quarterly on March 31,
June  30,  September  30  and December 31.  Payment of the principal and accrued
interest on the promissory notes was due on June 30, 1998.  On December 1, 1998,
the  Company completed a rollover and assignment agreement effectively extending
the  due  date  of  the  promissory  notes  until  June  30, 1999 (the "Rollover
Agreement").  In  connection  with the Rollover Agreement, the Company agreed to
assign its rights to any net cash collected from the Judgment towards any unpaid
principal  and  interest owing on the promissory notes.  The Company also agreed
to use any net proceeds received by the Company from any public offering of debt
or  equity of the Company in excess of than $2,250,000, towards the repayment of
any balances owing under the promissory notes.  The promissory note holders also
received  additional  warrants  to  purchase  337,500  shares  of  common stock,
exercisable  until  November  30, 2001, at an exercise price of $1.75 per share.
The  purchasers  in  the  private placement were granted one demand registration
right  with  respect  to  the  shares  issuable  upon  exercise of the warrants.

     On  November 13, 1998, the Company issued 250,000 shares of common stock of
the  Company  and  warrants  to  purchase  75,000 shares of common stock with an
exercise  price of $1.25 per warrant and an expiration date of November 12, 2000
for  an  amount  of  $250,000.  Net proceeds from the sale were used for working
capital  purposes.

     On  December 14, 1998, the Company issued 500,000 shares of common stock of
the  Company  and  warrants  to  purchase 300,000 shares of common stock with an
exercise  price of $1.75 per warrant and an expiration date of December 13, 2003
for  an amount of $500,000.  Net proceeds from the sale will be used for working
capital  purposes.

     During  December  1998, the Company issued 53,884 shares of common stock of
the  Company  to  Zimmerman  Holdings  Inc.  (ZHI),  as  payment  for  and  full
cancellation  of  a  note  payable  of  $100,000  and related interest and other
obligations  totaling  $18,000 and the cancellation of any further obligation to
pay  any  future  royalties in connection with Company's purchase of certain CNG
assets  from  Wilson  Technologies  Inc.,  a  wholly  owned  subsidiary  of ZHI.

                                       24

     Judgment  in  favor of the Company.  Judgment has been rendered in favor of
the  Company  in  connection  with its litigation against IBC-Brownsville in the
amount  of $3.2 million.  As of October 31, 1998, the net amount of the award is
approximately  $3.5  million,  which is comprised of the sum of (i) the original
award,  including  attorney's  fees,  (ii)  post-award  interest,  and  (iii)
cancellation  of  the note and accrued interest payable which is included in the
Consolidated  Financial Statements, less attorneys' fees.  The Judgment is being
appealed  by  the  defendant.  Although  no  assurance  can  be made, management
believes that the Company will ultimately prevail on appeal and will receive the
proceeds  from  such  Judgment.  A  significant  portion  of  the Judgment, upon
realization  by  the  Company,  will  be used to pay attorneys' fees incurred in
connection with the IBC-Brownsville litigation. In addition, a former officer of
the  Company  is  entitled  to  5% of the net proceeds (after expenses and legal
fees)  and  amounts have been assigned to the promissory note holders.  See note
and  L  to  the  Consolidated  Financial  Statements.

     Realization  of  Assets.  Recoverability of a major portion of the recorded
asset amounts on the Company's balance sheet is dependent upon the collection of
the  Judgment, the Company's ability to obtain additional financing and to raise
additional  equity  capital, and the success of the Company's future operations.

     To  provide  the Company with the ability it believes necessary to continue
in  existence,  management  is  taking  steps  to (i) collect the Judgment, (ii)
increase  sales to its current customers, (iii) increase its customer base, (iv)
extend the terms and capacity of the Pipeline Lease and the Brownsville Terminal
Facility,  (v)  expand  its  product lines and (vi) raise additional debt and/or
equity  capital.  See  note  I  to  the  Consolidated  Financial  Statements.

     Year 2000 Date Conversion.  Management has determined that the consequences
of  its  Year  2000  issues  will  not  have  a material effect on the Company's
business,  results  of  operations,  or  financial  condition.

FINANCIAL  ACCOUNTING  STANDARDS

     In February 1997, the Financial Accounting Standards Board issued Statement
of  Financial Accounting Standards No. 128 (SFAS 128), Earnings per Share.  SFAS
128  supersedes  APB  Opinion  No.  15 (Opinion No. 15), Earnings per Share, and
requires the calculation and dual presentation of basic and diluted earnings per
share (EPS), replacing the measures of primary and fully-diluted EPS as reported
under Opinion No. 15.  SFAS 128 became effective for financial statements issued
for  periods  ending  after  December  15,  1997;  earlier  application  was not
permitted.  Accordingly,  EPS  for  the  periods  presented  in the accompanying
consolidated  statements of operations are calculated under the guidance of SFAS
128.

     In  June 1997, the Financial Accounting Standards Board issued Statement of
Financial  Accounting  Standards  No.  130  (SFAS  130), Reporting Comprehensive
Income  and  Statement  of  Financial  Accounting  Standards No. 131 (SFAS 131),
Disclosure  about  Segments  of an Enterprise and Related Information.  Both are
effective  for  periods  beginning  after  December  15,  1997,  with  earlier
application  encouraged  for  SFAS  131.  The Company adopted SFAS 131 in fiscal
1997.

          advisors (if any), such independent investigation of the Borrower, its
          management,  and  related  matters as the  Lender  deems to be, or the
          Lender's  advisors (if any) have advised to be, necessary or advisable
          in connection  with this  investment;  and the Lender and its advisors
          (if any) have received all  information  and data which the Lender and
          its  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 Lender understands that all the Lender's representations
          and warranties  contained in this Rollover Agreement will be deemed to
          have been reaffirmed and confirmed as of the Closing.

                                        6
<PAGE>
               (v) The Lender  understands  that  acceptance  of the  Securities
          involves  various  risks,  including the risk that it is unlikely that
          any market  will exist for any resale of the  Securities,  the Warrant
          Shares or the Conversion Shares and that resale of the Securities, the
          Warrant Shares or the  Conversion  Shares will be restricted as herein
          provided.

     c. Status of Lender:
        ----------------

               (i) The Lender  either  alone or with its  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 Lender has
          deemed it  appropriate  to do so, the Lender has  retained  and relied
          upon,  appropriate  professional advice regarding the investment,  tax
          and legal  merits and  consequences  of this  Rollover  Agreement  and
          owning the Securities,  the Warrant Shares and the Conversion  Shares,
          as the case may be.

     d. Restrictions on Transfer or Sale:
        ------------------------------------

               (i) The Lender is acquiring the Securities and any Warrant Shares
          purchased  upon  exercise of the  Warrants or  Conversion  Shares upon
          conversion of Amended Notes solely for its own account, for investment
          purposes,  and not with a view to, or for resale in  connection  with,
          any  distribution  of the Amended  Note,  the Warrants or such Warrant
          Shares or Conversion  Shares.  The Lender understands that neither the
          Amended  Note,  the Warrants  nor such  underlying  Warrant  Shares or
          Conversion  Shares 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  Lender  and on the  other
          representations  made by the Lender in this  Rollover  Agreement.  The
          Lender   understands   that  the   Borrower   is   relying   upon  the
          representations  and agreements  contained in this Rollover  Agreement
          (and any  supplemental  information)  for the  purpose of  determining
          whether this transaction meets the requirements for such exemptions.

               (ii) The Lender  understands  that the Amended Note, the Warrants
          and  such  underlying   Warrant  Shares  and  Conversion   Shares  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 Lender 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  Borrower  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  Lender  understands  that  under  the
          Commission's  rules,  unless  disposed  of  pursuant  to an  effective
          registration statement under the

                                        7
<PAGE>
          Securities Act, the Lender may dispose of the Amended Note,  Warrants,
          underlying  Warrant  Shares and  Conversion  Shares 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,  or  pursuant  to such other
          exemptions  as may be  available  in which event the  transferee  will
          acquire "restricted  securities" subject to the same limitations as in
          the hands of the Lender.  As a  consequence,  absent such an effective
          registration   statement   under  the   Securities   Act,  the  Lender
          understands  that it may be required to bear the economic risks of the
          investment in the Securities  (and the  underlying  Warrant Shares and
          Conversion Shares) for an indefinite period of time.

               (iii)  The  Lender  agrees  that  (a) it will not  sell,  assign,
          pledge, give, transfer,  of otherwise dispose of the Amended Note, the
          Warrants or such underlying Warrant Shares or Conversion Shares 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 Lender  satisfactory to the Borrower (which requirement may be
          waived by the  Borrower  upon advice of  counsel),  is exempt from the
          registration provisions of the Securities Act and any applicable State
          Securities  Laws;  (b)  the  Amended  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 Borrower 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  Lender  in the
          Registration   Rights   Agreement  are  not  assignable  or  otherwise
          transferrable by the Lender except for assignment to affiliates and/or
          subsidiaries of the Lenders.  In no event shall any sale,  assignment,
          pledge or  transfer  of the  Warrants,  Warrant  Shares or  Conversion
          Shares by the Lender to a transferee give rise to any rights under the
          Registration  Rights  Agreement  except for  assignment  to affiliates
          and/or subsidiaries of the Lenders.

     11.  Conditions to Obligations of Lender and the Borrower.  The obligations
          ----------------------------------------------------
of each of the  Lenders  and the  Borrower  under this  Rollover  Agreement  are
subject  to the  satisfaction  at or  prior  to  the  Closing  of the  following

     Section 9 hereof and of each Lender contained in Section 10 hereof shall be

     the Closing.

discharge or termination is sought.

withheld, except for Assignments to affiliates and/or subsidiaries of Lender.

     14.  Applicable  Law.  This  Rollover  Agreement  shall be  governed by and

                            Redwood City, California


     FOR  VALUE  RECEIVED,  PENN OCTANE CORPORATION, a Delaware corporation (the

hereunder  (collectively,  the "Maturity Date"), at which time all principal and
any  accrued  and  unpaid  interest  thereon  shall  be  due  and  owing.

     This  Amended Note was issued under and is entitled to the benefits of that
certain  Rollover  and  Assignment  Agreement  dated as of December 1, 1998 (the
"Rollover  Agreement")  dated  the date hereof by and among the Borrower and the
Lenders as set forth in Schedule I of the Agreement.  All capitalized terms used
                        ----------

     This Amended Note shall accrue interest from the date hereof at the rate of
ten percent (10%) per annum, payable on December 31, 1998, March 31 and June 30,
1999  (or  the  Maturity  Date, if earlier).  Upon the occurrence of an Event of
Default  (as  defined  herein),  all amounts owing under this Amended Note shall
become  immediately  due  and  payable  and interest shall accrue thereon at the
default  interest  rate  of  twelve  percent  (12%)  per  annum until the entire
principal  balance  of  this  Amended Note and all interest accrued hereon shall
have  been  paid  in  full  and  the  Holder  may exercise all of its rights and
remedies  under  the  Rollover  Agreement  and  all  other documents executed or
delivered  in  connection  therewith  and/or  applicable  law.  Payment  of this
Amended Note may be enforced by suit or other process of law.  This Amended 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 of prepayment.

     The Borrower shall pay the sum of $__________ to the holder on December 11,
1998 which sum represents accrued and unpaid interest to December 1, 1998 on the
Original  Note  (the  "Original  Note  Interest).

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

       The  Borrower shall be in default hereunder upon the occurrence of any of
the  following  events of default ("Events of Default"):  (i) the failure by the
Borrower  to pay the Original Note Interest when due hereunder; (ii) the failure
by the Borrower to make any payment (other than the Original Note Interest) when
due  hereunder  and  such  failure shall have continued for a period of ten (10)
days; (iii) the commencement by the Borrower 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 Borrower a bankrupt or the appointment
of a receiver or trustee of the Borrower upon the application of any creditor in
an insolvency or bankruptcy proceeding or other creditor's suit; (iv) a petition
for  reorganization, liquidation or arrangement filed against the Borrower under
the  Federal  bankruptcy  laws  and  such petition shall not have been dismissed

<PAGE>
within thirty (30) days after it was filed; (v) an assignment for the benefit of
creditors by the Borrower; (vi) the occurrence of any event of default under the
terms  of  any  indebtedness  of  the  Borrower  for borrowed money in excess of
$50,000;  (vii)  the  existence  of  any  final,  non-appealable judgment on any
Amended Note or any final, non-appealable judgment in excess of $50,000 against,
or any attachment of material property, of the Borrower; or (viii) the breach of
any  representation,  warranty  or  covenant  (other  than  as  described in the
preceding  clauses (i) through (vii)) of Borrower in the Rollover Agreement, the
Assignment  of  Judgment or Collateral Agreement, and, if such breach is capable
of  cure, the failure of Borrower to cure such breach within a period of fifteen
(15)  days,  provided  that  such  breach  is  capable  of  cure.

     If  any payment owing under this Amended Note is not paid when due, whether
at  maturity  or  by  acceleration  or otherwise, the Borrower 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  Borrower, or involving any endorser or guarantor hereof,
which  in  any  way  affects  the  exercise  by  Holder hereof of its rights and
remedies  under  this  Amended  Note.

     If  any  payment remains owing under this Amended Note after June 30, 1999,
the  Holder  hereof  shall  have  certain  conversion  rights in respect of such
Amended  Note  as  set  forth  in  Section  7A  of  the  Rollover  Agreement.

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

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

     No  delay  on the part of the Holder in the exercise of any right or remedy
shall  operate  as a waiver thereto, and no single or partial exercise by Holder
of  any  right  or  remedy  shall  preclude  the further exercise thereof or the
exercise  of  any  other  right  or  remedy.

     Any  provision  in  this  Amended  Note  that  is  held  to be inoperative,
unenforceable,  voidable  or  invalid  in  any  jurisdiction  shall,  as to that
jurisdiction,  be  ineffective, unenforceable, void or invalid without affecting
the  remaining  provisions  in  any  other  jurisdiction,  and  to  this end the
provisions  of  this  Amended  Note  are  declared  to  be  severable.

<PAGE>
     This  Amended  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.


     IN  WITNESS WHEREOF, and intending to be legally bound hereby, the Borrower
has caused this Amended Note to be executed by its duly authorized officer as of
the  date  first  above  written.

                       COMMON STOCK ISSUABLE UPON EXERCISE
          HEREOF HAVE BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933,
          AS AMENDED (THE "ACT"), OR THE SECURITIES LAWS OF ANY STATE.
          NEITHER THIS WARRANT NOR THE SHARES OF COMMON STOCK ISSUABLE
          UPON EXERCISE HEREOF MAY BE SOLD OR OTHERWISE TRANSFERRED IN
          THE ABSENCE OF REGISTRATION OR QUALIFICATION OR AN EXEMPTION

                          COMMON STOCK PURCHASE WARRANT
                          Void after November 30, 2001

                                               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  November  30, 2001 (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 $1.75 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

<PAGE>
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

<PAGE>
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 number and kind of securities purchasable upon exercise or exchange of
this  Warrant  and the Exercise Price in effect immediately prior to such action
shall  each 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.

<PAGE>
              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.  If the Company so defers
making  any  such  adjustment and 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, shall be issued
promptly  upon  the  occurrence  of  such event and the Company shall pay 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.

<PAGE>
     (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

<PAGE>
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 or a portion thereof in accordance
with the terms hereof.  The closing on such  repurchase  shall occur on the date
and at the time set forth in such notice at the office of the Company in Redwood
City,  California  or at such other place as shall be agreed upon by the Company
and the  Holder.  At the  Closing,  the Company  shall  deliver to the Holder an
amount equal to the purchase price in immediately available funds and the Holder
will  deliver this  Warrant to the Company for  cancellation.  To the extent any
repurchase  hereunder  is of less  than all of the  rights  represented  by this
Warrant,  the  Company  will  deliver to the Holder a new Warrant  covering  the
rights not so purchased.

     11. Determination by Board of Directors. All determinations by the Board of
         -----------------------------------
Directors of the Company  under the  provisions  of this Warrant will be made in
good faith with due regard to the interest of the Holder and in accordance  with
sound financial practices.

     12. Notice. All notices to the Holder shall be in writing,  and all notices
         ------
and certificates given to the Holder shall be sent registered or certified mail,
return receipt requested, to such Holder at his address appearing on the records
of the Company.

     13.  Replacement of Lost,  Stolen,  Destroyed or Mutilated  Warrants.  Upon
          ---------------------------------------------------------------
receipt of evidence  reasonably  satisfactory to the Company of the loss, theft,
destruction  or  mutilation  of this  Warrant and, in the case of any such loss,
theft or  destruction,  upon delivery of any indemnity  bond in such  reasonable
amount as the Company may determine in the case of any such mutilation, upon the
surrender of such  Warrant for  cancellation,  the Company at its expense,  will
execute  and  deliver,  in lieu of such lost,  stolen,  destroyed  or  mutilated
Warrant, a new Warrant of like tenor.

     14.  Number and Gender.  Whenever the singular  number is used herein,  the
         ------------------
same shall include the plural where  appropriate,  and words of any gender shall
include each other gender where appropriate.

<PAGE>
     15.  Applicable  Law.  This Warrant  shall be governed by, and construed in
          ---------------
accordance  with,  the laws of the  State of New  York,  without  regard  to its
conflict of laws principles.

     This Registration Rights Agreement (this "Agreement") is entered into as of

2.   Securities  Subject  to  this  Agreement
     ----------------------------------------

The  securities  entitled  to the benefits of this Agreement are the Registrable
Securities.

3.   "Piggy-Back"  Registrations.
     ---------------------------

     (a) If at any time the  Borrower  shall  determine  to register  any of its
Common  Stock under the  Securities  Act,  whether in  connection  with a public
offering by the Borrower, a public offering by shareholders, or both, including,
without  limitation,  by means of any shelf  registration  pursuant  to Rule 415
under the  Securities  Act or any similar rule or  regulation,  but other than a
registration to implement an employee benefit or dividend reinvestment plan, the
Borrower  shall promptly give written notice thereof to the Lenders who shall be
registered  holders  of  Registrable  Securities  and shall  use its  reasonable
efforts to effect the registration  under the Securities Act of such Registrable
Securities as may be requested in a writing  delivered to the Borrower within 30
days after such  notice by the  Lenders as well as to include  such  Registrable
Securities in any notifications, registrations or qualifications under any state
securities  laws which shall be made or obtained with respect to the  securities
being registered by the Borrower;  provided,  however, that (a) any distribution
                                   --------   -------
of Registrable Securities pursu-ant to such registration shall be managed by the
investment  banking firm, if any,  managing the  distribution  of the securities
being  offered by the Borrower on the same terms as all other  securities  to be
registered,  and (b) the Borrower  shall not be required under this Section 3 to
include Registrable Securities in any registration of securities if the Borrower
shall have been advised by the investment  banking firm managing the offering of
the  securities  proposed to be  registered  by the  Borrower or others that the
inclusion  of  Registrable  Securities  in  such  offering  would  substantially
interfere with the orderly sale of such securities  which the Borrower or others
propose to register;  provided,  however, that in making any determination under
this  subparagraph (b) as to the inclusion of the Registrable  Securities in any
such offering,  Registrable  Securities  shall be registered on a pro-rata basis
with any other  securities  as to which the  Borrower  has granted or may in the
future grant registration  rights. All expenses of any registration and offering
of Registrable Securities

                                        2
<PAGE>
pursuant to this Section 3 (including, without limitation, registration fees and
fees  and  disbursements  of  the  Borrower's  counsel)  shall  be  borne by the
Borrower,  except  that  the  Borrower shall not bear underwrit-ing discounts or
commissions  attributable  to  Registrable  Securities, the fees of any separate
counsel  for  the  holders  of Registrable Securities or related transfer taxes.

4.   Registration  Procedures.
     ------------------------

     (a) In connection with any registration  pursuant to Section 3 hereof,  the
Borrower will prepare and file with the SEC, a Registration  Statement,  and any
amendments  and  supplements  thereto,  on any form for which the Borrower  then
qualifies or which counsel for the Borrower shall deem appropriate,  and use its
reasonable  efforts to cause such  Registration  Statement to become  effective;
provided that before filing with the SEC a Registration  Statement or prospectus
- --------
or any  amendments  or  supplements  thereto,  the Borrower  will (i) furnish to
counsel  selected by the  Lenders  copies of all such  documents  proposed to be
filed,  which documents will be subject to the review of such counsel,  and (ii)
notify the Lenders of any stop order  issued or  threatened  by the SEC and take
all  reasonable  actions  required to prevent the entry of such stop order or to
remove it if entered.  The Borrower will also (i) promptly notify each Lender of
the  effectiveness of such Registration  Statement,  (ii) furnish to each Lender
such number of copies of such  Registration  Statement,  and each  amendment and
supplement thereto,  the Prospectus included in such Registration  Statement and
such other  documents  as such  Lender  may  reasonably  request;  (iii) use its
reasonable efforts to register or qualify such securities to be registered under
such other  securities or blue sky laws of such  jurisdictions  as any Purchaser
reasonably  requests;  (iv)  use  its  reasonable  efforts  to  cause  all  such
securities to be registered  to be listed on each  securities  exchange on which
similar  securities  issued by the Borrower  are then  listed,  and to provide a
transfer agent and registrar for such  securities to be registered no later than
the  effective  date  of  such  Registration  Statement;  (v)  enter  in to such
customary agreements (including an underwriting agreement in customary form) and
take all such other actions as the Lenders or the  underwriters  retained by the
Lenders,  if any,  reasonably  request in order to  expedite or  facilitate  the
disposition   of  such   securities  to  be  registered,   including   customary
indemnification;  and (vi) otherwise use its  reasonable  efforts to comply with
all  applicable  rules and  regulations  of the SEC. The terms of this Section 4
shall not  require  the  Borrower  to qualify as a foreign  corporation  or as a
dealer in  securities  or to execute or file any  general  consent to service of
process under the laws of any such jurisdiction where it is not so subject.

     (b) In connection with any effective  Registration Statement filed pursuant
to  this   Agreement,   the  Borrower  will   immediately   notify  each  Lender
participating in the distribution to which such  Registration  Statement relates
of the  happening of any event as a result of which the  prospectus  included in
such Registration  Statement  contains an untrue statement of a material fact or
omits to state any material fact  required to be stated  therein or necessary to
make the statements  therein not misleading in light of the  circumstances  then
existing, and will promptly prepare and furnish to each such Lender a supplement
or  amendment to such  prospectus  so that such  prospectus  will not contain an
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 not misleading
in light of the circumstances then existing.  Notwithstanding the foregoing,  if
the Borrower determines in its reasonable business judgment that an amendment or
supplement to any such prospectus  would interfere with any material  financing,
acquisition, corporate reorganization, or other material

                                        3
<PAGE>
corporate  transaction  or  development involving the Borrower, the Borrower may
delay the preparation and filing of such amendment or supplement for a period of
up to 60 days in order to complete or make a public announcement with respect to
such  material transaction or development (it being understood that the Borrower
shall  be  obligated  to extend the period of time it is required to maintain in
effect  any  such Registration Statement to take into account the period of time
that the Lenders are unable to offer or sell Registrable Securities by reason of
this  Section  4(c)).


<PAGE>
5.   Holdback  Agreements.
     --------------------

     (a) Restrictions on Public Sale by Holders of Registrable Securities.  Each
         ----------------------------------------------------------------
holder of Registrable  Securities whose Registrable  Securities are covered by a
Registration  Statement filed pursuant to Section 3 hereof agrees,  if requested
by the managing  underwriters in an underwritten  offering (to the extent timely
notified in writing by the Borrower or the managing underwriters), not to effect
any public  sale or  distribution  of  securities  of the  Borrower of any class
included in such Registration  Statement,  including a sale pursuant to Rule 144
(except as part of such underwritten  offering),  during the 10-day period prior
to, and the 90-day period  beginning on, the effective date of any  Registration
Statement.

     (b) The foregoing  provisions  shall not apply to any holder of Registrable
Securities if such holder is prevented by applicable  statute or regulation from
entering into any such agreement;  provided, however, that any such holder shall
                                   -----------------
undertake in its request to participate in any such underwritten offering not to
effect any public sale or  distribution  of the class of Registrable  Securities
covered by such  Registration  Statement  (except  as part of such  underwritten
offering) during such period unless it has provided five (5) business days prior
written  notice of such sale or  distribution  to the  managing  underwriter  or
underwriters.

6.   Indemnification
     ---------------

     (a)  Indemnification  by Borrower.  The Borrower  shall  indemnify and hold
          ----------------------------
harmless,  to the full  extent  permitted  by law,  each  holder of  Registrable
Securities,  its  officers,  directors,  agents and  employees,  each person who
controls such holder  (within the meaning of Section 15 of the Securities Act or
Section  20 of the  Exchange  Act),  and  the  officers,  directors,  agents  or
employees of any such controlling person,  from and against all losses,  claims,
damages,  liabilities,  costs  (including,  without  limitation,  all reasonable
attorneys' fees) and expenses (collectively,  "Losses"), arising out of or based
upon any untrue  statement  of a material  fact  contained  in any  Registration
Statement, Prospectus or preliminary prospectus, or arising out of or based upon
any omission of 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 (in the case of any Prospectus) not misleading,  except insofar as the same
are based solely upon  information  furnished to the Borrower by such holder for
use therein;  provided,  however,  that the Borrower  shall not be liable in any
              ------------------
such case to the  extent  that any such Loss  arises  out of or is based upon an
untrue statement or omission made in any preliminary prospectus or Prospectus if
(i) such holder failed to send or deliver a copy of the Prospectus or Prospectus
supplement with or prior to the delivery of written  confirmation of the sale of
Registrable  Securities and (ii) the Prospectus or Prospectus  supplement  would
have corrected such untrue statement or omission.

     (b) Indemnification by Holder of Registrable Securities. In connection with
         ---------------------------------------------------
any  Registration  Statement  in which a holder  of  Registrable  Securities  is
participating,  such  holder of  Registrable  Securities  shall  furnish  to the
Borrower in writing such information as the Borrower may reasonably

                                        4
<PAGE>
request  for  use  in  connection with any Registration Statement or Prospectus.
Each  Lender  shall indemnify and hold harmless, to the full extent permitted by
law,  the  Borrower,  and  its  officers,  directors, agents and employees, each
person  who  controls  the  Borrower  (within  the  meaning of Section 15 of the
Securities  Act  or Section 20 of the Exchange Act) and the officers, directors,
agents  or employees of any such controlling person, from and against all Losses
arising  out  of or based upon any untrue statement of a material fact contained
in  any Registration Statement, Prospectus or preliminary prospectus, or arising
out  of  or  based  upon  any  omission of 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 (in the case of any Prospectus) not
misleading, to the extent, but only to the extent, that such untrue statement or
omission  is contained in any information so furnished in writing by such holder
to  the  Borrower  for  use  in  such  Registration  Statement,  Prospectus  or
preliminary  prospectus.  Such  indemnity  shall remain in full force and effect
regardless  of  any  investigation  made  by or on behalf of the Borrower or any
holder  and  any  of  their respective directors, officers, agents, employees or
controlling  persons  (within the meaning of Section 15 of the Securities Act or
Section  20  of  the  Exchange  Act)  and  shall  survive  the  transfer of such
securities  by  such  holder.

     (c) Conduct of  Indemnification  Proceedings.  If any action or  proceeding
         ----------------------------------------
(including any  governmental  investigation  or inquiry) shall be brought or any
claim shall be asserted  against any person entitled to indemnity  hereunder (an
"indemnified  party"),  such  indemnified  party shall promptly notify the party
from which such indemnity is sought (the "indemnifying  party") in writing,  and
the  indemnifying  party  shall  assume  the  defense  thereof,   including  the
employment of counsel  reasonably  satisfactory to the indemnified party and the
payment  of all  fees and  expenses  incurred  in  connection  with the  defense
thereof. All such fees and expenses (including any fees and expenses incurred in
connection with  investigating or preparing to defend such action or proceeding)
incurred by the indemnified  party,  shall be paid to the indemnified  party, as
incurred,  within 20 days of written notice thereof to the  indemnifying  party;
provided,  however, that if, in accordance with this Section 6, the indemnifying
- ------------------
party is not liable to the  indemnified  party,  such fees and expenses shall be
returned  promptly to the indemnifying  party. Any such indemnified  party shall
have  the  right  to  employ  separate  counsel  in any  such  action,  claim or
proceeding and to participate in the defense thereof,  but the fees and expenses
of such counsel  shall be the expense of such  indemnified  party unless (a) the
indemnifying  party  has  agreed  to  pay  such  fees  and  expenses,   (b)  the
indemnifying  party  shall have  failed  promptly  to assume the defense of such
action, claim or proceeding and to employ counsel reasonably satisfactory to the
indemnified  party in any such  action,  claim or  proceeding,  or (c) the named
parties  to any  such  action,  claim or  proceeding  (including  any  impleaded
parties)  include both such indemnified  party and the  indemnifying  party, and
such indemnified  party shall have been advised by counsel that there may be one
or more legal defenses available to it which are different from or additional to
those available to the  indemnifying  party (in which case, if such  indemnified
party  notifies  the  indemnifying  party in  writing  that it  elects to employ
separate  counsel at the expense of the  indemnifying  party,  the  indemnifying
party  shall not have the right to assume the defense of such  action,  claim or
proceeding on behalf of such indemnified  party, it being  understood,  however,
that the  indemnifying  party shall not, in connection with any one such action,
claim or proceeding or separate but  substantially  similar or related  actions,
claims or proceedings in the same  jurisdiction  arising out of the same general
allegations or circumstances,  be liable for the reasonable fees and expenses of
more than one  separate  firm of  attorneys  (together  with  appropriate  local
counsel) at any time for all such indemnified parties,  unless in the opinion of
counsel for such indemnified party a conflict of interest may exist between such
indemnified party and any other of such indemnified parties with respect to such
action,  claim or  proceeding,  in which event the  indemnifying  party shall be
obligated to pay the fees and expenses of such additional  counsel or counsels).
No  indemnifying  party will  consent to entry of any judgment or enter into any
settlement which does not include as an unconditional term thereof the release

                                        5
<PAGE>
of  such  indemnified  party  from  all  liability  in  respect to such claim or
litigation  without  the written consent (which consent will not be unreasonably
withheld) of the indemnified party.  No indemnified party shall consent to entry
of any judgment or enter into any set-tlement without the written consent (which
consent  will not be unreasonably withheld) of the indemnifying party from which
indemnity  or  contribution  is  sought.

     (d)  Contribution.  If the  indemnification  provided for in this Section 6
          ------------
from the indemnifying  party is unavailable to an in-demnified  party in respect
of any Losses,  then each applicable  indemnifying party in lieu of indemnifying
such indemnified  party hereunder shall contribute to the amount paid or payable
by such indemnified  party as a result of such Losses,  in such proportion as is
appropriate  to  reflect  the  relative  fault  of the  indemnifying  party  and
indemnified party in connection with the actions,  statements or omissions which
resulted in such Losses as well as any other relevant equitable  considerations.
The relative fault of such indemnifying party and the indemnified party shall be
determined by reference to, among other things,  whether any action in question,
including  any untrue  statement  of a material  fact or  omission of a material
fact,  has been taken or made by, or relates to  information  supplied  by, such
indemnifying  party or  indemnified  party,  and the parties'  relative  intent,
knowledge,  access to  information  and  opportunity  to correct or prevent such
action, statement or omission. The amount paid or payable by a party as a result
of any Losses shall be deemed to include,  subject to the  limitations set forth
in Section 6(c), any legal or other fees or expenses reasonably incurred by such
party in connection with any action, suit, claim, investigation or proceeding.

     The  parties  hereto  agree  that  it  would  not  be just and equitable if
contribution  pursuant  to  this  Section  6(d)  were  determined  by  pro  rata
allocation or by any other method of allocation which does not take into account
the equitable considerations referred to in the immediately preceding paragraph.
No  person guilty of fraudulent misrepresentation (within the meaning of Section
11(f)  of  the Securities Act) shall be entitled to contribution from any person
who  was  not  guilty  of  such  fraudulent  misrepresentation.

7.   Rule  144
     ---------

     The  Borrower  shall  file the reports required to be filed by it under the
Securities Act and the Exchange Act and the rules and regulations adopted by the
Commission  thereunder,  and  will  take  such  further  action as any holder of
Registrable  Securities  may reasonably request, all to the extent required from
time  to  time  to  enable  such  holder  to sell Registrable Securities without
registration  under  the  Securities  Act within the limitation of the exemption
provided  by  Rule  144  or  Rule  144A.  Upon  the  request  of  any  holder of
Registrable  Securities,  the  Borrower  shall  deliver to such holder a written
statement  as  to  whether  the  Borrower has complied with such information and
requirements.  Notwithstanding the foregoing, nothing in this Section 7 shall be
deemed  to  require  the  Borrower  to  register any of its securities under any
section  of  the  Exchange  Act.

8.   Underwritten  Registrations
     ---------------------------

     If  any of the Registrable Securities covered by any registration are to be
sold  in  an  underwritten offering, the investment banker or investment bankers
and  manager  or  managers that will administer the offering will be selected by
the  Borrower.  No  Lender  may  participate  in  any  underwritten registration
hereunder  unless  such  Lender  (i)  agrees  to  sell such Lender's Registrable
Securities  on  the  basis provided in the underwriting arrangements approved by
the  Borrower,  and  (ii)  completes  and executes all questionnaires, powers of
attorney,  indemnities,  underwriting  agreements  and  other documents required
under  the  terms  of  such  underwriting  arrangements.

         ------------
Agreement is held by a court of competent  jurisdiction  to be invalid,  void or
unenforceable,   the   remainder  of  the  terms,   provisions,   covenants  and
restrictions set forth herein shall remain in full force and effect and shall in
no way be affected,  impaired or  invalidated,  and the parties hereto shall use
their best efforts to find and employ an  alternative  means to achieve the same
or substantially the same result as that  contemplated by such term,  provision,
covenant or restriction. It is hereby stipulated and declared to be the

                                        7

intention  of  the  parties  that  they would have executed the remaining terms,
provisions,  covenants  and restrictions without including any of such which may
be  hereafter  declared  invalid,  void  or  unenforceable.

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

matter contained  herein.  There are no restrictions,  promises,  warranties nor
undertakings,  other than those set forth or referred to herein with  respect to
the  registration  rights granted by the Borrower with respect to the securities
sold pursuant to the Rollover  Agreement.  This  Agreement  supersedes all prior
agreements and  understandings  between the parties with respect to such subject
matter.

attorneys'  fees in addition to its costs and expenses  and any other  available
remedy.

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


     THIS COLLATERAL AGREEMENT ("Collateral Agreement") is entered into this 1st
day  of  December  1998,  by  and  among (i) Penn Octane Corporation, a Delaware
corporation, (the "Borrower"); (ii) each of the individual lenders identified on
the  signature  pages hereto (each a "Lender", and collectively, the "Lenders");
and  Castle  Energy  Corporation, as collateral agent  (the "Collateral Agent").

                              W I T N E S S E T H:
                              -------------------

     WHEREAS,  Borrower  has  represented to Lenders that: an arbitral award was
rendered  against International Bank of Commerce-Brownsville ("IBC") in favor of
Borrower;  the value of the arbitral award as of July 31, 1998 was approximately
$3.4  million; a judgment was entered on February 28, 1996 by the 197th District
Court  of  Cameron  County,  Texas  in  Civil  Action No. 94-08-4008-C, known as
International  Energy  Development  Corp.  v.  International  Bank  of
- ----------------------------------------------------------------------
Commerce-Brownsville;  such  judgment  modified  the  arbitral  award in certain
- --------------------
respects;  an  appeal  was  taken  to  the  Court  of Appeals for the Thirteenth
District of Texas (the "Corpus Christi Court of Appeals"); on June 18, 1998, the
Corpus  Christi  Court  of  Appeals  rendered  an  Opinion  and  Order  in  No.
13-96-298-CV,  known  as International Bank of Commerce - Brownsville, Appellant
                         -------------------------------------------------------
v.  International  Energy  Development  Corp.,  Appellee, such Opinion and Order
- --------------------------------------------------------
confirmed  the  original  arbitral  award  in  all respects; and IBC has filed a
motion  for  rehearing  with  the  Corps  Christi  Court  of  Appeals;

     WHEREAS,  Borrower  has  represented  to  Lenders that International Energy
Development Corp. changed its name to Penn Octane Corporation but the caption of
the Judgment (as defined in the Assignment) continues to reflect the prior name.

     WHEREAS,  pursuant  to a Rollover and Assignment Agreement by and among the
Borrower  and  the  Lenders  of even date herewith ("Rollover Agreement") and an
Assignment  of Judgment Agreement between Borrower and Castle Energy Corporation
for  itself  and  as Collateral Agent for Lenders dated as of even date herewith
(the  "Assignment")  the  Borrower  has  assigned  in  trust  to  Castle  Energy
Corporation for itself and as Collateral Agent for the Lenders all of its right,
title  and  interest  in and to the Judgment and the Proceeds (as defined in the
Assignment);

     WHEREAS,  in  furtherance  of  the  Assignment,  the Borrower has agreed to
execute  and  deliver to Collateral Agent at Closing (as defined in the Rollover
Agreement) a letter to IBC, substantially in the form attached hereto as Annex 1
                                                                         -------
(the  "Payment  Instruction  Letter") instructing IBC to deliver the Proceeds in
trust  to  the  Collateral  Agent  for  deposit  in  the  Collateral Account (as
hereinafter  defined);

     WHEREAS, the Borrower and the Lenders wish to appoint the Collateral Agent,
and the Collateral Agent has agreed to establish a deposit account in trust (the
"Collateral  Account") and to act, as an administrator of the Collateral Account
upon  the  terms,  conditions  and  provisions  hereinafter  set  forth;  and

<PAGE>
     WHEREAS,  the  Borrower  and  the Lenders desire to set forth the terms and
conditions  pursuant  to  which  the Collateral Agent shall pay out any Proceeds
delivered  to  the Collateral Agent and/or deposited into the Collateral Account
during  the  term  of  this  Agreement.

     NOW,  THEREFORE,  in  consideration  of  the  mutual promises and covenants
contained  herein  and  other  good  and valuable consideration, the receipt and
sufficiency  of which are hereby acknowledged, and intending to be legally bound
hereby,  it  is  hereby  agreed  among  the  parties  hereto  as  follows:

1.   Defined  Terms
     --------------

     All  capitalized  terms used herein, unless otherwise defined herein, shall
have  the respective meanings ascribed to them in the Rollover Agreement and are
incorporated  herein  by  reference.

2.   Appointment  of  the  Collateral  Agent
     ---------------------------------------

     2.1 The Borrower and the Lenders hereby designate the Collateral Agent, and
the Collateral Agent hereby agrees to act, as an administrator of the Collateral
Account in trust, upon the terms and conditions set forth herein.

     2.2 The Collateral Agent's duties and responsibilities,  in its capacity as
such,  shall  be  limited  to  those  expressly  set  forth  in this  Collateral
Agreement,  and the  Collateral  Agent  shall not be subject  to, nor obliged to
recognize,  any other  agreement  between any or all of the parties  hereto even
though  reference  thereto  may  be  made  herein,  except  to the  extent  that
definitions  contained  in the  Rollover  Agreement  are  incorporated  in  this
Collateral  Agreement.  This Collateral Agreement may not be amended at any time
in  such  a  way  as  to  affect  the  rights,  responsibilities,   obligations,
liabilities or fees of the Collateral  Agent except with the Collateral  Agent's
prior written  consent,  as evidenced by an instrument in writing  signed by all
the parties hereto.

     2.3 The Collateral  Agent, in its capacity as such, shall disregard any and
all notices or directions  given by any of the  Borrower,  the Lenders or by any
other  person,  firm or  corporation,  except (i) such notices,  directions  and
instructions as are specifically  provided for herein,  (ii) joint  instructions
received in writing  from the  Borrower  and the Lenders and (iii) a Final Order
(as hereinafter defined) of a court of competent  jurisdiction.  If any property
subject hereto is at any time  attached,  garnished or levied upon under a Final
Order of a court of competent jurisdiction,  or in case the payment, assignment,
transfer,  conveyance  or  delivery  of any such  property  shall be  stayed  or
enjoined by a Final  Order of a court of  competent  jurisdiction,  or in case a
Final  Order  of a court of  competent  jurisdiction  shall  be made or  entered
affecting such property or any part thereof,  then and in any of such events the
Collateral  Agent is  authorized  to rely upon and comply  with any such  order,
writ,  judgment or decree of any court which is not subject to further review or
appeal (a "Final Order").

     2.4 In the event that the  Collateral  Agent shall be  uncertain  as to its
duties or actions hereunder,  or shall receive instructions from the Borrower or
the Lenders which, in the opinion of the Collateral  Agent, are in conflict with
any of the  provisions  of this  Collateral  Agreement,  it shall be entitled to
maintain the Collateral Account and may decline to take any further action until
the Collateral Agent receives joint written  instructions  from the Borrower and
the Lenders  directing the disbursement of all or any portion of such Collateral
Account, in which case the Collateral Agent shall then make such disbursement in
accordance with such instructions.  Should any dispute arise with respect to the

                                        2
<PAGE>
payment,  ownership or right of  possession  of any proposed  disbursement,  the
Collateral Agent is authorized and directed to retain in its possession, without
liability to anyone,  all or any part of such proposed  disbursement  until such
dispute  shall  have been  settled  either by mutual  agreement  of the  parties
concerned or by a Final Order, provided that the Collateral Agent shall be under
no duty whatsoever to institute or defend any such  proceedings,  and,  provided
further,  that if any such dispute  continues  for more than one hundred  twenty
(120) days, the Collateral Agent may, in its discretion,  upon written notice to
the Borrower and the Lenders, interplead the Collateral Account (or that portion
thereof  which  is  the  subject  of  such  dispute)  to a  court  of  competent
jurisdiction (subject to the provisions of Section 7.4 hereof).
                                           -----------

     2.5 It is understood and agreed that the Collateral Agent shall:

          (a) be under no duty to accept notices or instructions from any person
     other than as expressly provided for in this Collateral Agreement;

          (b)  be  protected  in  acting  upon  any  notice,  opinion,  request,
     certificate,  approval, consent or other document reasonably believed by it
     to be genuine and what it purports to be;

          (c) be deemed  conclusively  to have  given and  delivered  any notice
     required  to be given or  delivered  hereunder  if the same is in  writing,
     signed by any one of its authorized  officers and (i) mailed, by registered
     or certified mail, return receipt requested, postage prepaid, (ii) sent via
     expedited   courier   service  that  regularly   requires  signed  receipts
     evidencing delivery, or (iii) hand delivered, in a sealed wrapper, manually
     receipted for by the addressee, in each case to the Borrower or the Lenders
     at the addresses set forth in Section 7.3 hereof;
                                   -----------

          (d) be protected,  indemnified and held harmless jointly and severally
     by the Borrower and the Lenders (other than Castle Energy Corporation) from
     and against any claim made against it by reason of its acting or failing to
     act in  connection  with any of the  transactions  contemplated  hereby and
     against any loss, liability or expense, including attorneys' fees and other
     reasonable  expenses of defending  itself against any claim of liability it
     may sustain in carrying out the terms of this Collateral Agreement,  except
     for claims which are  successfully  asserted  against the Collateral  Agent
     based upon the  Collateral  Agent's  failure  to comply  with the terms and

5.   Lenders'  Rights
     ----------------

     The  Borrower  and each of the Lenders hereby acknowledge that neither this
Collateral  Agreement  nor  the Assignment shall in any way prejudice any of the
Lenders' rights to payment under the Rollover Agreement or the Amended Notes, or

The  Borrower  specifically acknowledges that this Collateral Agreement has been
established  for  purposes  of  effecting  the  equitable  distribution  of  any

owed  to  them  by  the Borrower.  The Borrower hereby confirms, and the parties
hereto  acknowledge,  the  Borrower's assignment to the Collateral Agent for the
benefit of itself and the Lenders of all of Borrower's right, title and interest

     jurisdiction,  whereupon  the  Collateral  Agent shall be discharged of and
     from any and all  further  obligations  arising  in  connection  with  this
     Collateral  Agreement,  but  without  prejudice  to  any  liability  of the
     Collateral Agent for its bad faith,  gross negligence or willful misconduct

DECEMBER  1,  1998

                             AMENDED PROMISSORY NOTE

                            Redwood City, California

     FOR  VALUE  RECEIVED,  PENN OCTANE CORPORATION, a Delaware corporation (the
"Borrower"),  promises  to pay to the order of CASTLE ENERGY CORPORATION, or its
assigns ("Holder"), at the office of the Borrower 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 ONE
MILLION  DOLLARS ($1,000,000), together with interest thereon, on the earlier of
(i)  June  30,  1999,  (ii)  a  date  determined by the Borrower within ten (10)
business  days of the closing date of any raising of debt or equity financing of
the  Borrower, resulting in net proceeds to the Borrower in excess of $2,250,000
or  (iii)  the  occurrence  of  an Event of Default hereunder (collectively, the
"Maturity  Date"),  at  which  time  all  principal  and  any accrued and unpaid
interest  thereon  shall  be  due  and  owing.

     This  Amended Note was issued under and is entitled to the benefits of that
certain  Rollover  and  Assignment  Agreement  dated as of December 1, 1998 (the
"Rollover  Agreement") by and among the Borrower and the Lenders as set forth in
Schedule  I of the Agreement.  All capitalized terms used herein and not defined
- -----------
shall  have  the  meanings  ascribed  to  them  in  the  Rollover  Agreement.

     This Amended Note shall accrue interest from the date hereof at the rate of
ten  percent  (10%)  per annum, payable on December 31, 1998, March 31, 1999 and
June  30,  1999  (or  the Maturity Date, if earlier).  Upon the occurrence of an
Event  of Default (as defined herein), all amounts owing under this Amended Note
shall  become  immediately  due and payable and interest shall accrue thereon at
the  default  interest  rate  of twelve percent (12%) per annum until the entire
principal  balance  of  this  Amended Note and all interest accrued hereon shall
have  been  paid  in  full  and  the  Holder  may exercise all of its rights and
remedies  under  the  Rollover  Agreement  and  all  other documents executed or
delivered  in  connection  therewith  and/or  applicable  law.  Payment  of this
Amended Note may be enforced by suit or other process of law.  This Amended 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 of prepayment.

     The  Borrower shall pay the sum of $41,917.81 to the Holder on December 11,
1998,  which  sum  represents accrued and unpaid interest to December 1, 1998 on
the  Original  Note  (the  "Original  Note  Interest").

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

       The  Borrower shall be in default hereunder upon the occurrence of any of
the  following  events of default ("Events of Default"):  (i) the failure by the
Borrower  to pay the Original Note Interest when due hereunder; (ii) the failure
by the Borrower to make any payment (other than the Original Note Interest) when
due  hereunder  and  such  failure shall have continued for a period of ten (10)
days; (iii) the commencement by the Borrower 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 Borrower a bankrupt or the appointment
of a receiver or trustee of the Borrower upon the application of any creditor in
an insolvency or bankruptcy proceeding or other creditor's suit; (iv) a petition
for  reorganization, liquidation or arrangement filed against the Borrower under
the  Federal  bankruptcy  laws  and  such petition shall not have been dismissed
within thirty (30) days after it was filed; (v) an assignment for the benefit of
creditors by the Borrower; (vi) the occurrence of any event of default under the

<PAGE>
terms  of  any  indebtedness  of  the  Borrower  for borrowed money in excess of
$50,000;  (vii)  the  existence  of  any  final,  non-appealable judgment on any
Amended Note or any final, non-appealable judgment in excess of $50,000 against,
or any attachment of material property, of the Borrower; or (viii) the breach of
any  representation,  warranty  or  covenant  (other  than  as  described in the
preceding  clauses (i) through (vii)) of Borrower in the Rollover Agreement, the
Assignment  of  Judgment or Collateral Agreement, and, if such breach is capable
of  cure,  the  failure  of  the Borrower to cure such breach within a period of
fifteen  (15)  days.

     If  any  pament owing under this Amended Note is not paid when due, whether
at  maturity  or  by  acceleration  or otherwise, the Borrower 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  Borrower, or involving any endorser or guarantor hereof,
which  in  any  way  affects  the  exercise  by  Holder hereof of its rights and
remedies  under  this  Amended  Note.

     If  any  payment remains owing under this Amended Note after June 30, 1999,
the  Holder  thereof  shall  have  certain  conversion rights in respect of such
Amended  Note  as  set  forth  in  Section  7A  of  the  Rollover  Agreement.

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

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

     No  delay  on the part of the Holder in the exercise of any right or remedy
shall  operate  as a waiver thereto, and no single or partial exercise by Holder
of  any  right  or  remedy  shall  preclude  the further exercise thereof or the
exercise  of  any  other  right  or  remedy.

     Any  provision  in  this  Amended  Note  that  is  held  to be inoperative,
unenforceable,  voidable  or  invalid  in  any  jurisdiction  shall,  as to that
jurisdiction,  be  ineffective, unenforceable, void or invalid without affecting
the  remaining  provisions  in  any  other  jurisdiction,  and  to  this end the
provisions  of  this  Amended  Note  are  declared  to  be  severable.

     This  Amended  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.

<PAGE>
     IN  WITNESS WHEREOF, and intending to be legally bound hereby, the Borrower
has caused this Amended Note to be executed by its duly authorized officer as of
the  date  first  above  written.

                     NEITHER THIS WARRANT NOR THE SHARES OF
                       COMMON STOCK ISSUABLE UPON EXERCISE
          HEREOF HAVE BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933,
          AS AMENDED (THE "ACT"), OR THE SECURITIES LAWS OF ANY STATE.
          NEITHER THIS WARRANT NOR THE SHARES OF COMMON STOCK ISSUABLE
          UPON EXERCISE HEREOF MAY BE SOLD OR OTHERWISE TRANSFERRED IN
          THE ABSENCE OF REGISTRATION OR QUALIFICATION OR AN EXEMPTION
                         THEREFROM UNDER APPLICABLE LAW.

                          COMMON STOCK PURCHASE WARRANT
                          Void after November 30, 2001

                                              Warrant to Purchase 225,000 Shares
                                                 of Common Stock, $.01 par value
                                                      of Penn Octane Corporation

                         PENN OCTANE CORPORATION (POCC)

This  is  to  Certify  That,  FOR  VALUE  RECEIVED,

                            Castle Energy Corporation

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  November  30, 2001 (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),  150,000  shares  of  Common  Stock,  $.01  par value, of the Company (the
"Common  Stock")  at an exercise price of $1.75 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

<PAGE>
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

<PAGE>
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 number and kind of securities purchasable upon exercise or exchange of
this  Warrant  and the Exercise Price in effect immediately prior to such action
shall  each 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.

<PAGE>
              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.  If the Company so defers making
any such  adjustment and 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,  shall be issued promptly upon
the  occurrence  of such event and the Company  shall pay 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.

<PAGE>
     (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

<PAGE>
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 or a portion thereof in accordance
with the terms hereof.  The closing on such  repurchase  shall occur on the date
and at the time set forth in such notice at the office of the Company in Redwood
City,  California  or at such other place as shall be agreed upon by the Company
and the  Holder.  At the  Closing,  the Company  shall  deliver to the Holder an
amount equal to the purchase price in immediately available funds and the Holder
will  deliver this  Warrant to the Company for  cancellation.  To the extent any
repurchase  hereunder  is of less  than all of the  rights  represented  by this
Warrant,  the  Company  will  deliver to the Holder a new Warrant  covering  the
rights not so purchased.

     11. Determination by Board of Directors. All determinations by the Board of
         -----------------------------------
Directors of the Company  under the  provisions  of this Warrant will be made in
good faith with due regard to the interest of the Holder and in accordance  with
sound financial practices.

     12. Notice. All notices to the Holder shall be in writing,  and all notices
         ------
and certificates given to the Holder shall be sent registered or certified mail,
return receipt requested, to such Holder at his address appearing on the records
of the Company.

     13.  Replacement of Lost,  Stolen,  Destroyed or Mutilated  Warrants.  Upon
          ---------------------------------------------------------------
receipt of evidence  reasonably  satisfactory to the Company of the loss, theft,
destruction  or  mutilation  of this  Warrant and, in the case of any such loss,
theft or  destruction,  upon delivery of any indemnity  bond in such  reasonable
amount as the Company may determine in the case of any such mutilation, upon the
surrender of such  Warrant for  cancellation,  the Company at its expense,  will
execute  and  deliver,  in lieu of such lost,  stolen,  destroyed  or  mutilated
Warrant, a new Warrant of like tenor.

     14.  Number and Gender.  Whenever the singular  number is used herein,  the
          -----------------
same shall include the plural where  appropriate,  and words of any gender shall
include each other gender where appropriate.

<PAGE>
     15.  Applicable  Law.  This Warrant  shall be governed by, and construed in
          ---------------
accordance  with,  the laws of the  State of New  York,  without  regard  to its
conflict of laws principles.

DECEMBER  1,  1998

                             AMENDED PROMISSORY NOTE
                             -----------------------

                            Redwood City, California

     FOR  VALUE  RECEIVED,  PENN OCTANE CORPORATION, a Delaware corporation (the
"Borrower"),  promises  to  pay  to  the  order  of CLINT NORTON, or his assigns
("Holder"),  at  the  office of the Borrower 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 NINETY
THOUSAND  DOLLARS  ($90,000),  together with interest thereon, on the earlier of
(i)  June  30,  1999,  (ii)  a  date  determined by the Borrower within ten (10)
business  days of the closing date of any raising of debt or equity financing of
the  Borrower, resulting in net proceeds to the Borrower in excess of $2,250,000
or  (iii)  the  occurrence  of  an Event of Default hereunder (collectively, the
"Maturity  Date"),  at  which  time  all  principal  and  any accrued and unpaid
interest  thereon  shall  be  due  and  owing.

     This  Amended Note was issued under and is entitled to the benefits of that
certain  Rollover  and  Assignment  Agreement  dated as of December 1, 1998 (the
"Rollover  Agreement") by and among the Borrower and the Lenders as set forth in
Schedule  I of the Agreement.  All capitalized terms used herein and not defined
- -----------
shall  have  the  meanings  ascribed  to  them  in  the  Agreement.

     This Amended Note shall accrue interest from the date hereof at the rate of
ten  percent  (10%)  per annum, payable on December 31, 1998, March 31, 1999 and
June  30,  1999  (or  the Maturity Date, if earlier).  Upon the occurrence of an
Event  of Default (as defined herein), all amounts owing under this Amended Note
shall  become  immediately  due and payable and interest shall accrue thereon at
the  default  interest  rate  of twelve percent (12%) per annum until the entire
principal  balance  of  this  Amended Note and all interest accrued hereon shall
have  been  paid  in  full  and  the  Holder  may exercise all of its rights and
remedies  under  the  Rollover  Agreement  and  all  other documents executed or
delivered  in  connection  therewith  and/or  applicable  law.  Payment  of this
Amended Note may be enforced by suit or other process of law.  This Amended 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 of prepayment.

     The  Borrower  shall pay the sum of $3,772.60 to the Holder on December 11,
1998,  which  sum  represents accrued and unpaid interest to December 1, 1998 on
the  Original  Note  ("Original  Note  Interest").

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

       The  Borrower shall be in default hereunder upon the occurrence of any of
the  following  events of default ("Events of Default"):  (i) the failure by the
Borrower  to pay the Original Note Interest when due hereunder; (ii) the failure
by the Borrower to make any payment (other than the Original Note Interest) when
due  hereunder  and  such  failure shall have continued for a period of ten (10)
days; (iii) the commencement by the Borrower 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 Borrower a bankrupt or the appointment
of a receiver or trustee of the Borrower upon the application of any creditor in
an insolvency or bankruptcy proceeding or other creditor's suit; (iv) a petition
for  reorganization, liquidation or arrangement filed against the Borrower under
the  Federal  bankruptcy  laws  and  such petition shall not have been dismissed
within thirty (30) days after it was filed; (v) an assignment for the benefit of
creditors by the Borrower; (vi) the occurrence of any event of default under the
terms  of  any  indebtedness  of  the  Borrower  for borrowed money in excess of

<PAGE>
$50,000;  (vii)  the  existence  of  any  final,  non-appealable judgment on any
Amended Note or any final, non-appealable judgment in excess of $50,000 against,
or any attachment of material property, of the Borrower; or (viii) the breach of
any  representation,  warranty  or  covenant  (other  than  as  described in the
preceding  clauses (i) through (vii)) of Borrower in the Rollover Agreement, the
Assignment  of  Judgment or Collateral Agreement, and, if such breach is capable
of  cure, the failure of Borrower to cure such breach within a period of fifteen
(15)  days.

     If  any payment owing under this Amended Note is not paid when due, whether
at  maturity  or  by  acceleration  or otherwise, the Borrower 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  Borrower, or involving any endorser or guarantor hereof,
which  in  any  way  affects  the  exercise  by  Holder hereof of its rights and
remedies  under  this  Amended  Note.

     If  any  payment remains owing under this Amended Note after June 30, 1999,
the  Holder  thereof  shall  have  certain  conversion rights in respect of such
Amended  Note  as  set  forth  in  Section  7A  of  the  Rollover  Agreement.

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

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

     No  delay  on the part of the Holder in the exercise of any right or remedy
shall  operate  as a waiver thereto, and no single or partial exercise by Holder
of  any  right  or  remedy  shall  preclude  the further exercise thereof or the
exercise  of  any  other  right  or  remedy.

     Any  provision  in  this  Amended  Note  that  is  held  to be inoperative,
unenforceable,  voidable  or  invalid  in  any  jurisdiction  shall,  as to that
jurisdiction,  be  ineffective, unenforceable, void or invalid without affecting
the  remaining  provisions  in  any  other  jurisdiction,  and  to  this end the
provisions  of  this  Amended  Note  are  declared  to  be  severable.

     This  Amended  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.

<PAGE>
     IN  WITNESS WHEREOF, and intending to be legally bound hereby, the Borrower
has caused this Amended Note to be executed by its duly authorized officer as of
the  date  first  above  written.

                     NEITHER THIS WARRANT NOR THE SHARES OF
                       COMMON STOCK ISSUABLE UPON EXERCISE
          HEREOF HAVE BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933,
          AS AMENDED (THE "ACT"), OR THE SECURITIES LAWS OF ANY STATE.
          NEITHER THIS WARRANT NOR THE SHARES OF COMMON STOCK ISSUABLE
          UPON EXERCISE HEREOF MAY BE SOLD OR OTHERWISE TRANSFERRED IN
          THE ABSENCE OF REGISTRATION OR QUALIFICATION OR AN EXEMPTION
                         THEREFROM UNDER APPLICABLE LAW.

                          COMMON STOCK PURCHASE WARRANT
                          Void after November 30, 2001

                                               Warrant to Purchase 20,250 Shares
                                                 of Common Stock, $.01 par value
                                                      of Penn Octane Corporation

                         PENN OCTANE CORPORATION (POCC)

This  is  to  Certify  That,  FOR  VALUE  RECEIVED,

                                  Clint Norton

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  November  30, 2001 (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), 13,500 shares of Common Stock, $.01 par value, of the Company (the "Common
Stock")  at  an  exercise  price of $1.75 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

<PAGE>
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

<PAGE>
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 number and kind of securities purchasable upon exercise or exchange of
this  Warrant  and the Exercise Price in effect immediately prior to such action
shall  each 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.

<PAGE>
              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.  If the Company so defers
making  any  such  adjustment and 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, shall be issued
promptly  upon  the  occurrence  of  such event and the Company shall pay 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.

<PAGE>
     (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

<PAGE>
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 or a portion thereof in accordance
with the terms hereof.  The closing on such  repurchase  shall occur on the date
and at the time set forth in such notice at the office of the Company in Redwood
City,  California  or at such other place as shall be agreed upon by the Company
and the  Holder.  At the  Closing,  the Company  shall  deliver to the Holder an
amount equal to the purchase price in immediately available funds and the Holder
will  deliver this  Warrant to the Company for  cancellation.  To the extent any
repurchase  hereunder  is of less  than all of the  rights  represented  by this
Warrant,  the  Company  will  deliver to the Holder a new Warrant  covering  the
rights not so purchased.

     11. Determination by Board of Directors. All determinations by the Board of
         -----------------------------------
Directors of the Company  under the  provisions  of this Warrant will be made in
good faith with due regard to the interest of the Holder and in accordance  with
sound financial practices.

     12. Notice. All notices to the Holder shall be in writing,  and all notices
         ------
and certificates given to the Holder shall be sent registered or certified mail,
return receipt requested, to such Holder at his address appearing on the records
of the Company.

     13.  Replacement of Lost,  Stolen,  Destroyed or Mutilated  Warrants.  Upon
          ---------------------------------------------------------------
receipt of evidence  reasonably  satisfactory to the Company of the loss, theft,
destruction  or  mutilation  of this  Warrant and, in the case of any such loss,
theft or  destruction,  upon delivery of any indemnity  bond in such  reasonable
amount as the Company may determine in the case of any such mutilation, upon the
surrender of such  Warrant for  cancellation,  the Company at its expense,  will
execute  and  deliver,  in lieu of such lost,  stolen,  destroyed  or  mutilated
Warrant, a new Warrant of like tenor.

     14.  Number and Gender.  Whenever the singular  number is used herein,  the
          -----------------
same shall include the plural where  appropriate,  and words of any gender shall
include each other gender where appropriate.

<PAGE>
     15.  Applicable  Law.  This Warrant  shall be governed by, and construed in
          ---------------
accordance  with,  the laws of the  State of New  York,  without  regard  to its
conflict of laws principles.

DECEMBER  1,  1998

                             AMENDED PROMISSORY NOTE
                             -----------------------

                            Redwood City, California

     FOR  VALUE  RECEIVED,  PENN OCTANE CORPORATION, a Delaware corporation (the
"Borrower"),  promises  to  pay  to  the order of SOUTHWEST CONCEPT INC., or its
assigns ("Holder"), at the office of the Borrower 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 SIXTY
THOUSAND  DOLLARS  ($60,000),  together with interest thereon, on the earlier of
(i)  June  30,  1999,  (ii)  a  date  determined by the Borrower within ten (10)
business  days of the closing date of any raising of debt or equity financing of
the  Borrower, resulting in net proceeds to the Borrower in excess of $2,250,000
or  (iii)  the  occurrence  of  an Event of Default hereunder (collectively, the
"Maturity  Date"),  at  which  time  all  principal  and  any accrued and unpaid
interest  thereon  shall  be  due  and  owing.

     This  Amended Note was issued under and is entitled to the benefits of that
certain  Rollover  and  Assignment  Agreement  dated as of December 1, 1998 (the
"Rollover  Agreement") by and among the Borrower and the Lenders as set forth in
Schedule  I of the Agreement.  All capitalized terms used herein and not defined
- -----------
shall  have  the  meanings  ascribed  to  them  in  the  Rollover  Agreement.

     This Amended Note shall accrue interest from the date hereof at the rate of
ten  percent  (10%)  per annum, payable on December 31, 1998, March 31, 1999 and
June  30,  1999  (or  the Maturity Date, if earlier).  Upon the occurrence of an
Event  of Default (as defined herein), all amounts owing under this Amended Note
shall  become  immediately  due and payable and interest shall accrue thereon at
the  default  interest  rate  of twelve percent (12%) per annum until the entire
principal  balance  of  this  Amended Note and all interest accrued hereon shall
have  been  paid  in  full  and  the  Holder  may exercise all of its rights and
remedies  under  the  Rollover  Agreement  and  all  other documents executed or
delivered  in  connection  therewith  and/or  applicable  law.  Payment  of this
Amended Note may be enforced by suit or other process of law.  This Amended 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 of prepayment.

     The  Borrower  shall pay the sum of $2,515.07 to the Holder on December 11,
1998,  which  sum  represents accrued and unpaid interest to December 1, 1998 on
the  Original  Note  (the  "Original  Note  Interest").

     All  payments  shall  be  payable  in  lawful  money  of the United States.

     The  Borrower  shall  be in default hereunder upon the occurrence of any of
the  following  events of default ("Events of Default"):  (i) the failure by the
Borrower  to pay the Original Note Interest when due hereunder; (ii) the failure
by the Borrower to make any payment (other than the Original Note Interest) when
due  hereunder  and  such  failure shall have continued for a period of ten (10)
days; (iii) the commencement by the Borrower 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 Borrower a bankrupt or the appointment
of a receiver or trustee of the Borrower upon the application of any creditor in
an insolvency or bankruptcy proceeding or other creditor's suit; (iv) a petition
for  reorganization, liquidation or arrangement filed against the Borrower under
the  Federal  bankruptcy  laws  and  such petition shall not have been dismissed
within thirty (30) days after it was filed; (v) an assignment for the benefit of
creditors by the Borrower; (vi) the occurrence of any event of default under the
terms  of  any  indebtedness  of  the  Borrower  for borrowed money in excess of

<PAGE>
$50,000;  (vii)  the  existence  of  any  final,  non-appealable judgment on any
Amended Note or any final, non-appealable judgment in excess of $50,000 against,
or any attachment of material property, of the Borrower; or (viii) the breach of
any  representation,  warranty  or  covenant  (other  than  as  described in the
preceding  clauses (i) through (vii)) of Borrower in the Rollover Agreement, the
Assignment  of  Judgment or Collateral Agreement, and, if such breach is capable
of  cure, the failure of Borrower to cure such breach within a period of fifteen
(15)  days.

     If  any payment owing under this Amended Note is not paid when due, whether
at  maturity  or  by  acceleration  or otherwise, the Borrower 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  Borrower, or involving any endorser or guarantor hereof,
which  in  any  way  affects  the  exercise  by  Holder hereof of its rights and
remedies  under  this  Amended  Note.

     If  any  payment remains owing under this Amended Note after June 30, 1999,
the  Holder  thereof  shall  have  certain  conversion rights in respect of such
Amended  Note  as  set  forth  in  Section  7A  of  the  Rollover  Agreement.

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

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

     No  delay  on the part of the Holder in the exercise of any right or remedy
shall  operate  as a waiver thereto, and no single or partial exercise by Holder
of  any  right  or  remedy  shall  preclude  the further exercise thereof or the
exercise  of  any  other  right  or  remedy.

     Any  provision  in  this  Amended  Note  that  is  held  to be inoperative,
unenforceable,  voidable  or  invalid  in  any  jurisdiction  shall,  as to that
jurisdiction,  be  ineffective, unenforceable, void or invalid without affecting
the  remaining  provisions  in  any  other  jurisdiction,  and  to  this end the
provisions  of  this  Amended  Note  are  declared  to  be  severable.

     This  Amended  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.

<PAGE>
     IN  WITNESS WHEREOF, and intending to be legally bound hereby, the Borrower
has caused this Amended Note to be executed by its duly authorized officer as of
the  date  first  above  written.

                     NEITHER THIS WARRANT NOR THE SHARES OF
                       COMMON STOCK ISSUABLE UPON EXERCISE
          HEREOF HAVE BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933,
          AS AMENDED (THE "ACT"), OR THE SECURITIES LAWS OF ANY STATE.
          NEITHER THIS WARRANT NOR THE SHARES OF COMMON STOCK ISSUABLE
          UPON EXERCISE HEREOF MAY BE SOLD OR OTHERWISE TRANSFERRED IN
          THE ABSENCE OF REGISTRATION OR QUALIFICATION OR AN EXEMPTION
                         THEREFROM UNDER APPLICABLE LAW.

                          COMMON STOCK PURCHASE WARRANT
                          Void after November 30, 2001

                                               Warrant to Purchase 13,500 Shares
                                                 of Common Stock, $.01 par value
                                                      of Penn Octane Corporation

                         PENN OCTANE CORPORATION (POCC)

This  is  to  Certify  That,  FOR  VALUE  RECEIVED,

                             Southwest Concept Inc.

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  November  30, 2001 (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),  9,000 shares of Common Stock, $.01 par value, of the Company (the "Common
Stock")  at  an  exercise  price of $1.75 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

<PAGE>
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 number and kind of securities purchasable upon exercise or exchange of
this  Warrant  and the Exercise Price in effect immediately prior to such action
shall  each 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.

<PAGE>
              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.  If the Company so defers
making  any  such  adjustment and 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, shall be issued
promptly  upon  the  occurrence  of  such event and the Company shall pay 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.

<PAGE>
     (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

<PAGE>
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 or a portion thereof in accordance
with the terms hereof.  The closing on such  repurchase  shall occur on the date
and at the time set forth in such notice at the office of the Company in Redwood
City,  California  or at such other place as shall be agreed upon by the Company
and the  Holder.  At the  Closing,  the Company  shall  deliver to the Holder an
amount equal to the purchase price in immediately available funds and the Holder
will  deliver this  Warrant to the Company for  cancellation.  To the extent any
repurchase  hereunder  is of less  than all of the  rights  represented  by this
Warrant,  the  Company  will  deliver to the Holder a new Warrant  covering  the
rights not so purchased.

     11. Determination by Board of Directors. All determinations by the Board of
         -----------------------------------
Directors of the Company  under the  provisions  of this Warrant will be made in
good faith with due regard to the interest of the Holder and in accordance  with
sound financial practices.

     12. Notice. All notices to the Holder shall be in writing,  and all notices
         ------
and certificates given to the Holder shall be sent registered or certified mail,
return receipt requested, to such Holder at his address appearing on the records
of the Company.

     13.  Replacement of Lost,  Stolen,  Destroyed or Mutilated  Warrants.  Upon
          ---------------------------------------------------------------
receipt of evidence  reasonably  satisfactory to the Company of the loss, theft,
destruction  or  mutilation  of this  Warrant and, in the case of any such loss,
theft or  destruction,  upon delivery of any indemnity  bond in such  reasonable
amount as the Company may determine in the case of any such mutilation, upon the
surrender of such  Warrant for  cancellation,  the Company at its expense,  will
execute  and  deliver,  in lieu of such lost,  stolen,  destroyed  or  mutilated
Warrant, a new Warrant of like tenor.

     14.  Number and Gender.  Whenever the singular  number is used herein,  the
          -----------------
same shall include the plural where  appropriate,  and words of any gender shall
include each other gender where appropriate.

<PAGE>
     15.  Applicable  Law.  This Warrant  shall be governed by, and construed in
          ---------------
accordance  with,  the laws of the  State of New  York,  without  regard  to its
conflict of laws principles.

DECEMBER  1,  1998

                             AMENDED PROMISSORY NOTE
                             -----------------------

                            Redwood City, California

     FOR  VALUE  RECEIVED,  PENN OCTANE CORPORATION, a Delaware corporation (the
"Borrower"), promises to pay to the order of JAMES F. MEARA, JR., or his assigns
("Holder"),  at  the  office of the Borrower 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 SEVENTY
FIVE  THOUSAND DOLLARS ($75,000), together with interest thereon, on the earlier
of  (i)  June  30,  1999, (ii) a date determined by the Borrower within ten (10)
business  days of the closing date of any raising of debt or equity financing of
the  Borrower, resulting in net proceeds to the Borrower in excess of $2,250,000
or  (iii)  the  occurrence  of  an Event of Default hereunder (collectively, the
"Maturity  Date"),  at  which  time  all  principal  and  any accrued and unpaid
interest  thereon  shall  be  due  and  owing.

     This  Amended Note was issued under and is entitled to the benefits of that
certain  Rollover  and  Assignment  Agreement  dated as of December 1, 1998 (the
"Rollover  Agreement") by and among the Borrower and the Lenders as set forth in
Schedule  I of the Agreement.  All capitalized terms used herein and not defined
- -----------
shall  have  the  meanings  ascribed  to  them  in  the  Rollover  Agreement.

     This Amended Note shall accrue interest from the date hereof at the rate of
ten  percent  (10%)  per annum, payable on December 31, 1998, March 31, 1999 and
June  30,  1999  (or  the Maturity Date, if earlier).  Upon the occurrence of an
Event  of Default (as defined herein), all amounts owing under this Amended Note
shall  become  immediately  due and payable and interest shall accrue thereon at
the  default  interest  rate  of twelve percent (12%) per annum until the entire
principal  balance  of  this  Amended Note and all interest accrued hereon shall
have  been  paid  in  full  and  the  Holder  may exercise all of its rights and
remedies  under  the  Rollover  Agreement  and  all  other documents executed or
delivered  in  connection  therewith  and/or  applicable  law.  Payment  of this
Amended Note may be enforced by suit or other process of law.  This Amended 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 of prepayment.

     The  Borrower  shall pay the sum of $3,143.84 to the Holder on December 11,
1998, which sum represents accrued and unpaid interest on the Original Note (the
"Original  Note  Interest").

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

       The  Borrower shall be in default hereunder upon the occurrence of any of
the  following  events of default ("Events of Default"):  (i) the failure by the
Borrower  to pay the Original Note Interest when due hereunder; (ii) the failure
by the Borrower to make any payment (other than the Original Note Interest) when
due  hereunder  and  such  failure shall have continued for a period of ten (10)
days; (iii) the commencement by the Borrower 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 Borrower a bankrupt or the appointment
of a receiver or trustee of the Borrower upon the application of any creditor in
an insolvency or bankruptcy proceeding or other creditor's suit; (iv) a petition
for  reorganization, liquidation or arrangement filed against the Borrower under
the  Federal  bankruptcy  laws  and  such petition shall not have been dismissed
within thirty (30) days after it was filed; (v) an assignment for the benefit of
creditors by the Borrower; (vi) the occurrence of any event of default under the
terms  of  any  indebtedness  of  the  Borrower  for borrowed money in excess of

<PAGE>
$50,000;  (vii)  the  existence  of  any  final,  non-appealable judgment on any
Amended Note or any final, non-appealable judgment in excess of $50,000 against,
or any attachment of material property, of the Borrower; or (viii) the breach of
any  representation,  warranty  or  covenant  (other  than  as  described in the
preceding  clauses (i) through (vii)) of Borrower in the Rollover Agreement, the
Assignment  of  Judgment or Collateral Agreement, and, if such breach is capable
of  cure, the failure of Borrower to cure such breach within a period of fifteen
(15)  days.

     If  any payment owing under this Amended Note is not paid when due, whether
at  maturity  or  by  acceleration  or otherwise, the Borrower 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  Borrower, or involving any endorser or guarantor hereof,
which  in  any  way  affects  the  exercise  by  Holder hereof of its rights and
remedies  under  this  Amended  Note.

     If  any  payment remains owing under this Amended Note after June 30, 1999,
the  Holder  thereof  shall  have  certain  conversion rights in respect of such
Amended  Note  as  set  forth  in  Section  7A  of  the  Rollover  Agreement.

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

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

     No  delay  on the part of the Holder in the exercise of any right or remedy
shall  operate  as a waiver thereto, and no single or partial exercise by Holder
of  any  right  or  remedy  shall  preclude  the further exercise thereof or the
exercise  of  any  other  right  or  remedy.

     Any  provision  in  this  Amended  Note  that  is  held  to be inoperative,
unenforceable,  voidable  or  invalid  in  any  jurisdiction  shall,  as to that
jurisdiction,  be  ineffective, unenforceable, void or invalid without affecting
the  remaining  provisions  in  any  other  jurisdiction,  and  to  this end the
provisions  of  this  Amended  Note  are  declared  to  be  severable.

     This  Amended  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.

<PAGE>
     IN  WITNESS WHEREOF, and intending to be legally bound hereby, the Borrower
has caused this Amended Note to be executed by its duly authorized officer as of
the  date  first  above  written.

Day), 11,250 shares of Common Stock, $.01 par value, of the Company (the "Common
Stock")  at  an  exercise  price of $1.75 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

<PAGE>
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

<PAGE>
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 number and kind of securities purchasable upon exercise or exchange of
this  Warrant  and the Exercise Price in effect immediately prior to such action
shall  each 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.

<PAGE>
              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.  If the Company so defers
making  any  such  adjustment and 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, shall be issued
promptly  upon  the  occurrence  of  such event and the Company shall pay 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.

<PAGE>
     (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

<PAGE>
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 or a portion thereof in accordance
with the terms hereof.  The closing on such  repurchase  shall occur on the date
and at the time set forth in such notice at the office of the Company in Redwood
City,  California  or at such other place as shall be agreed upon by the Company
and the  Holder.  At the  Closing,  the Company  shall  deliver to the Holder an
amount equal to the purchase price in immediately available funds and the Holder
will  deliver this  Warrant to the Company for  cancellation.  To the extent any
repurchase  hereunder  is of less  than all of the  rights  represented  by this
Warrant,  the  Company  will  deliver to the Holder a new Warrant  covering  the
rights not so purchased.

     11. Determination by Board of Directors. All determinations by the Board of
         -----------------------------------
Directors of the Company  under the  provisions  of this Warrant will be made in
good faith with due regard to the interest of the Holder and in accordance  with
sound financial practices.

     12. Notice. All notices to the Holder shall be in writing,  and all notices
         ------
and certificates given to the Holder shall be sent registered or certified mail,
return receipt requested, to such Holder at his address appearing on the records
of the Company.

     13.  Replacement of Lost,  Stolen,  Destroyed or Mutilated  Warrants.  Upon
          ---------------------------------------------------------------
receipt of evidence  reasonably  satisfactory to the Company of the loss, theft,
destruction  or  mutilation  of this  Warrant and, in the case of any such loss,
theft or  destruction,  upon delivery of any indemnity  bond in such  reasonable
amount as the Company may determine in the case of any such mutilation, upon the
surrender of such  Warrant for  cancellation,  the Company at its expense,  will
execute  and  deliver,  in lieu of such lost,  stolen,  destroyed  or  mutilated
Warrant, a new Warrant of like tenor.

     14.  Number and Gender.  Whenever the singular  number is used herein,  the
          -----------------
same shall include the plural where  appropriate,  and words of any gender shall
include each other gender where appropriate.

<PAGE>
     15.  Applicable  Law.  This Warrant  shall be governed by, and construed in
          ---------------
accordance  with,  the laws of the  State of New  York,  without  regard  to its
conflict of laws principles.

DECEMBER  1,  1998

                             AMENDED PROMISSORY NOTE
                             -----------------------

                            Redwood City, California

     FOR  VALUE  RECEIVED,  PENN OCTANE CORPORATION, a Delaware corporation (the

SECURITIES  CORPORATION  CUSTODIAN  SEP  FBO  JAMES F. MEARA IRA, or its assigns
("Holder"),  at  the  office of the Borrower 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 SEVENTY
FIVE  THOUSAND DOLLARS ($75,000), together with interest thereon, on the earlier
of  (i)  June  30,  1999, (ii) a date determined by the Borrower within ten (10)
business  days of the closing date of any raising of debt or equity financing of
the  Borrower, resulting in net proceeds to the Borrower in excess of $2,250,000
or  (iii)  the  occurrence  of  an Event of Default hereunder (collectively, the
"Maturity  Date"),  at  which  time  all  principal  and  any accrued and unpaid
interest  thereon  shall  be  due  and  owing.

     This  Amended Note was issued under and is entitled to the benefits of that
certain  Rollover  and  Assignment  Agreement  dated as of December 1, 1998 (the

Schedule  I of the Agreement.  All capitalized terms used herein and not defined
- -----------
shall  have  the  meanings  ascribed  to  them  in  the  Rollover  Agreement.

     This Amended Note shall accrue interest from the date hereof at the rate of
ten  percent  (10%)  per annum, payable on December 31, 1998, March 31, 1999 and

the  following  events of default ("Events of Default"):  (i) the failure by the
Borrower  to pay the Original Note Interest when due hereunder; (ii) the failure
by the Borrower to make any payment (other than the Original Note Interest) when
due  hereunder  and  such  failure shall have continued for a period of ten (10)

any  representation,  warranty  or  covenant  (other  than  as  described in the
preceding  clauses (i) through (vii)) of Borrower in the Rollover Agreement, the
Assignment  of  Judgment or Collateral Agreement, and, if such breach is capable
of  cure, the failure of Borrower to cure such breach within a period of fifteen
(15)  days.

     If  any payment owing under this Amended Note is not paid when due, whether
at  maturity  or  by  acceleration  or otherwise, the Borrower 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  Borrower, or involving any endorser or guarantor hereof,
which  in  any  way  affects  the  exercise  by  Holder hereof of its rights and
remedies  under  this  Amended  Note.

     If  any  payment remains owing under this Amended Note after June 30, 1999,
the  Holder  thereof  shall  have  certain  conversion rights in respect of such
Amended  Note  as  set  forth  in  Section  7A  of  the  Rollover  Agreement.

     Presentment,  demand,  protest, notice of protest, dishonor and non-payment

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

     No  delay  on the part of the Holder in the exercise of any right or remedy
shall  operate  as a waiver thereto, and no single or partial exercise by Holder
of  any  right  or  remedy  shall  preclude  the further exercise thereof or the
exercise  of  any  other  right  or  remedy.

     Any  provision  in  this  Amended  Note  that  is  held  to be inoperative,
unenforceable,  voidable  or  invalid  in  any  jurisdiction  shall,  as to that
jurisdiction,  be  ineffective, unenforceable, void or invalid without affecting

                       COMMON STOCK ISSUABLE UPON EXERCISE
          HEREOF HAVE BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933,

          UPON EXERCISE HEREOF MAY BE SOLD OR OTHERWISE TRANSFERRED IN

                          COMMON STOCK PURCHASE WARRANT
                          Void after November 30, 2001

                                               Warrant to Purchase 16,875 Shares
                                                 of Common Stock, $.01 par value
                                                      of Penn Octane Corporation

                         PENN OCTANE CORPORATION (POCC)

This  is  to  Certify  That,  FOR  VALUE  RECEIVED,

           Donaldson Lufkin Jenrette Securities Corporation Custodian
                           SEP FBO James F. Meara IRA

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  November  30, 2001 (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), 11,250 shares of Common Stock, $.01 par value, of the Company (the "Common
Stock")  at  an  exercise  price of $1.75 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

<PAGE>
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

<PAGE>
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 number and kind of securities purchasable upon exercise or exchange of
this  Warrant  and the Exercise Price in effect immediately prior to such action
shall  each 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.

<PAGE>
              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.  If the Company so defers
making  any  such  adjustment and 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, shall be issued
promptly  upon  the  occurrence  of  such event and the Company shall pay 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.

<PAGE>
     (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

<PAGE>
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 or a portion thereof in accordance
with the terms hereof.  The closing on such  repurchase  shall occur on the date
and at the time set forth in such notice at the office of the Company in Redwood
City,  California  or at such other place as shall be agreed upon by the Company
and the  Holder.  At the  Closing,  the Company  shall  deliver to the Holder an
amount equal to the purchase price in immediately available funds and the Holder
will  deliver this  Warrant to the Company for  cancellation.  To the extent any
repurchase  hereunder  is of less  than all of the  rights  represented  by this
Warrant,  the  Company  will  deliver to the Holder a new Warrant  covering  the
rights not so purchased.

     11. Determination by Board of Directors. All determinations by the Board of
         -----------------------------------
Directors of the Company  under the  provisions  of this Warrant will be made in
good faith with due regard to the interest of the Holder and in accordance  with
sound financial practices.

     12. Notice. All notices to the Holder shall be in writing,  and all notices
         ------
and certificates given to the Holder shall be sent registered or certified mail,
return receipt requested, to such Holder at his address appearing on the records
of the Company.

     13.  Replacement of Lost,  Stolen,  Destroyed or Mutilated  Warrants.  Upon
          ---------------------------------------------------------------
receipt of evidence  reasonably  satisfactory to the Company of the loss, theft,
destruction  or  mutilation  of this  Warrant and, in the case of any such loss,
theft or  destruction,  upon delivery of any indemnity  bond in such  reasonable
amount as the Company may determine in the case of any such mutilation, upon the
surrender of such  Warrant for  cancellation,  the Company at its expense,  will
execute  and  deliver,  in lieu of such lost,  stolen,  destroyed  or  mutilated
Warrant, a new Warrant of like tenor.

     14.  Number and Gender.  Whenever the singular  number is used herein,  the
          -----------------
same shall include the plural where  appropriate,  and words of any gender shall
include each other gender where appropriate.

<PAGE>
     15.  Applicable  Law.  This Warrant  shall be governed by, and construed in
          ---------------
accordance  with,  the laws of the  State of New  York,  without  regard  to its
conflict of laws principles.

DECEMBER  1,  1998

                             AMENDED PROMISSORY NOTE
                             -----------------------

                            Redwood City, California

     FOR  VALUE  RECEIVED,  PENN OCTANE CORPORATION, a Delaware corporation (the
"Borrower"),  promises  to  pay  to  the  order of LINCOLN TRUST COMPANY, or its
assigns ("Holder"), at the office of the Borrower 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 TWO
HUNDRED  THOUSAND  DOLLARS  ($200,000),  together  with interest thereon, on the
earlier  of (i) June 30, 1999, (ii) a date determined by the Borrower within ten
(10)  business  days  of  the  closing  date  of  any  raising of debt or equity
financing  of  the Borrower, resulting in net proceeds to the Borrower in excess
of  $2,250,000  or  (iii)  the  occurrence  of  an  Event  of  Default hereunder
(collectively, the "Maturity Date"), at which time all principal and any accrued
and  unpaid  interest  thereon  shall  be  due  and  owing.

     This  Amended Note was issued under and is entitled to the benefits of that
certain  Rollover  and  Assignment  Agreement  dated as of December 1, 1998 (the
"Rollover  Agreement") by and among the Borrower and the Lenders as set forth in
Schedule  I of the Agreement.  All capitalized terms used herein and not defined
- -----------
shall  have  the  meanings  ascribed  to  them  in  the  Rollover  Agreement.

     This Amended Note shall accrue interest from the date hereof at the rate of
ten  percent  (10%)  per annum, payable on December 31, 1998, March 31, 1999 and
June  30,  1999  (or  the Maturity Date, if earlier).  Upon the occurrence of an
Event  of Default (as defined herein), all amounts owing under this Amended Note
shall  become  immediately  due and payable and interest shall accrue thereon at
the  default  interest  rate  of twelve percent (12%) per annum until the entire
principal  balance  of  this  Amended Note and all interest accrued hereon shall
have  been  paid  in  full  and  the  Holder  may exercise all of its rights and
remedies  under  the  Rollover  Agreement  and  all  other documents executed or
delivered  in  connection  therewith  and/or  applicable  law.  Payment  of this
Amended Note may be enforced by suit or other process of law.  This Amended 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 of prepayment.

     The  Borrower  shall pay the sum of $8,383.56 to the Holder on December 11,
1998,  which  sum  represents accrued and unpaid interest to December 1, 1998 on
the  Original  Note  (the  "Original  Note  Interest").

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

       The  Borrower shall be in default hereunder upon the occurrence of any of
the  following  events of default ("Events of Default"):  (i) the failure by the
Borrower  to pay the Original Note Interest when due hereunder; (ii) the failure
by the Borrower to make any payment (other than the Original Note Interest) when
due  hereunder  and  such  failure shall have continued for a period of ten (10)
days; (iii) the commencement by the Borrower of a voluntary case in a bankruptcy

<PAGE>
or  insolvency  proceeding  or  the  entry  of  a  decree or order by a court of
competent  jurisdiction  adjudicating the Borrower a bankrupt or the appointment
of a receiver or trustee of the Borrower upon the application of any creditor in
an insolvency or bankruptcy proceeding or other creditor's suit; (iv) a petition
for  reorganization, liquidation or arrangement filed against the Borrower under
the  Federal  bankruptcy  laws  and  such petition shall not have been dismissed
within thirty (30) days after it was filed; (v) an assignment for the benefit of
creditors by the Borrower; (vi) the occurrence of any event of default under the
terms  of  any  indebtedness  of  the  Borrower  for borrowed money in excess of
$50,000;  (vii)  the  existence  of  any  final,  non-appealable judgment on any
Amended Note or any final, non-appealable judgment in excess of $50,000 against,
or any attachment of material property, of the Borrower; or (viii) the breach of
any  representation,  warranty  or  covenant  (other  than  as  described in the
preceding  clauses (i) through (vii)) of Borrower in the Rollover Agreement, the
Assignment  of  Judgment or Collateral Agreement, and, if such breach is capable
of  cure, the failure of Borrower to cure such breach within a period of fifteen
(15)  days.

     If  any payment owing under this Amended Note is not paid when due, whether
at  maturity  or  by  acceleration  or otherwise, the Borrower 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  Borrower, or involving any endorser or guarantor hereof,
which  in  any  way  affects  the  exercise  by  Holder hereof of its rights and
remedies  under  this  Amended  Note.

     If  any  payment remains owing under this Amended Note after June 30, 1999,
the  Holder  thereof  shall  have  certain  conversion rights in respect of such
Amended  Note  as  set  forth  in  Section  7A  of  the  Rollover  Agreement.

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

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

     No  delay  on the part of the Holder in the exercise of any right or remedy
shall  operate  as a waiver thereto, and no single or partial exercise by Holder
of  any  right  or  remedy  shall  preclude  the further exercise thereof or the
exercise  of  any  other  right  or  remedy.

     Any  provision  in  this  Amended  Note  that  is  held  to be inoperative,
unenforceable,  voidable  or  invalid  in  any  jurisdiction  shall,  as to that
jurisdiction,  be  ineffective, unenforceable, void or invalid without affecting
the  remaining  provisions  in  any  other  jurisdiction,  and  to  this end the
provisions  of  this  Amended  Note  are  declared  to  be  severable.

     This  Amended  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.

<PAGE>
     IN  WITNESS WHEREOF, and intending to be legally bound hereby, the Borrower
has caused this Amended Note to be executed by its duly authorized officer as of
the  date  first  above  written.

                     NEITHER THIS WARRANT NOR THE SHARES OF
                       COMMON STOCK ISSUABLE UPON EXERCISE
          HEREOF HAVE BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933,
          AS AMENDED (THE "ACT"), OR THE SECURITIES LAWS OF ANY STATE.
          NEITHER THIS WARRANT NOR THE SHARES OF COMMON STOCK ISSUABLE
          UPON EXERCISE HEREOF MAY BE SOLD OR OTHERWISE TRANSFERRED IN
          THE ABSENCE OF REGISTRATION OR QUALIFICATION OR AN EXEMPTION
                         THEREFROM UNDER APPLICABLE LAW.

                          COMMON STOCK PURCHASE WARRANT
                          Void after November 30, 2001

                                               Warrant to Purchase 45,000 Shares
                                                 of Common Stock, $.01 par value
                                                      of Penn Octane Corporation

                         PENN OCTANE CORPORATION (POCC)

This  is  to  Certify  That,  FOR  VALUE  RECEIVED,

                              Lincoln Trust Company

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  November  30, 2001 (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), 30,000 shares of Common Stock, $.01 par value, of the Company (the "Common
Stock")  at  an  exercise  price of $1.75 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

<PAGE>
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

<PAGE>
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 number and kind of securities purchasable upon exercise or exchange of
this  Warrant  and the Exercise Price in effect immediately prior to such action
shall  each 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.

<PAGE>
              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.  If the Company so defers
making  any  such  adjustment and 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, shall be issued
promptly  upon  the  occurrence  of  such event and the Company shall pay 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.

<PAGE>
     (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

<PAGE>
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 or a portion thereof in accordance
with the terms hereof.  The closing on such  repurchase  shall occur on the date
and at the time set forth in such notice at the office of the Company in Redwood
City,  California  or at such other place as shall be agreed upon by the Company
and the  Holder.  At the  Closing,  the Company  shall  deliver to the Holder an
amount equal to the purchase price in immediately available funds and the Holder
will  deliver this  Warrant to the Company for  cancellation.  To the extent any
repurchase  hereunder  is of less  than all of the  rights  represented  by this
Warrant,  the  Company  will  deliver to the Holder a new Warrant  covering  the
rights not so purchased.

     11. Determination by Board of Directors. All determinations by the Board of
         -----------------------------------
Directors of the Company  under the  provisions  of this Warrant will be made in
good faith with due regard to the interest of the Holder and in accordance  with
sound financial practices.

     12. Notice. All notices to the Holder shall be in writing,  and all notices
         ------
and certificates given to the Holder shall be sent registered or certified mail,
return receipt requested, to such Holder at his address appearing on the records
of the Company.

     13.  Replacement of Lost,  Stolen,  Destroyed or Mutilated  Warrants.  Upon
          ---------------------------------------------------------------
receipt of evidence  reasonably  satisfactory to the Company of the loss, theft,
destruction  or  mutilation  of this  Warrant and, in the case of any such loss,
theft or  destruction,  upon delivery of any indemnity  bond in such  reasonable
amount as the Company may determine in the case of any such mutilation, upon the
surrender of such  Warrant for  cancellation,  the Company at its expense,  will
execute  and  deliver,  in lieu of such lost,  stolen,  destroyed  or  mutilated
Warrant, a new Warrant of like tenor.

     14.  Number and Gender.  Whenever the singular  number is used herein,  the
          -----------------
same shall include the plural where  appropriate,  and words of any gender shall
include each other gender where appropriate.

<PAGE>
     15.  Applicable  Law.  This Warrant  shall be governed by, and construed in
          ---------------
accordance  with,  the laws of the  State of New  York,  without  regard  to its
conflict of laws principles.

                               PURCHASE AGREEMENT
                               ------------------


     THIS  PURCHASE  AGREEMENT made and entered into as of November __, 1998, by

125,000  shares (the "Warrant Shares") of Common Stock substantially in the form
of  Exhibit  1  hereto  (the  "Warrant"; the Shares and the Warrant being herein
collectively  referred  to  as  the  "Securities");  and

     WHEREAS,  the Company and the Purchaser desire to enter into a Registration
Rights  Agreement  with  respect  to  the  Shares  and  the  Warrant  Shares,
substantially  in the form annexed as Exhibit 2 hereto (the "Registration Rights

     NOW,  THEREFORE,  in consideration of the agreements and obligations herein

     1. Purchase and Sale of the Securities. Subject to the terms and conditions
        -----------------------------------
set forth in this  Agreement,  the Company agrees to sell to the Purchaser,  and
the Purchaser agrees to purchase from the Company, the Securities for a purchase

<PAGE>
     2. The Closing. The closing (the "Closing") of the purchase and sale of the
        -----------
Securities shall take place on November 13, 1998 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  Purchaser  shall  agree.  At the  Closing,  the
Purchaser  shall  deliver  to the  Company  payment  for  the  Securities  being

Shares and the Warrant to the Purchaser.

     3. Registration  Rights. The Purchaser shall have such registration  rights
        --------------------
with  respect  to the  Share  and 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 Warrant and
     payment  therefor,  will be  legally  and  validly  issued,  fully paid and
     nonassessable.

     5.   Representations  and  Warranties  of  the  Purchaser.   The  Purchaser
          ----------------------------------------------------
represents and warrants as follows:

                                       2
<PAGE>
          (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.

                                       3
<PAGE>
               (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 Warrant and that resale of
          the Shares,  the Warrant 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 Shares,  the Warrant 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 Warrant solely for its own
          account,  for  investment  purposes,  and not with a view  to,  or for
          resale in connection with, any distribution of the Shares, the Warrant
          or such shares of Common Stock. The Purchaser understands that neither
          the Shares,  the Warrant 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.

                                       4
<PAGE>
               (ii) The Purchaser  understands that the Shares,  the Warrant 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  Shares,  the
          Warrant 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 Shares, the Warrant and any certificate(s)  representing
          shares of Common Stock issued upon  exercise of the Warrant may bear a
          legend  making  reference to the foregoing  restrictions;  and (c) the
          Company and any transfer agent for shares of its

                                       5
<PAGE>
          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) In no event shall any sale,  assignment,  pledge or transfer
          of the Shares,  the  Warrant or such  underlying  Common  Stock by the
          Purchaser to a transferee  give rise to rights of any such  transferee
          under the Registration Rights Agreement.

     6. Conditions to Obligations of Purchaser and the Company.  The obligations
        ------------------------------------------------------
of the Purchaser to purchase and pay for the Securities  specified herein and of
the Company to sell and deliver such Securities are subject to the  satisfaction

     the Closing.

          (b)  The  Company  and  the  Purchaser  shall  each  have  received  a
     certificate from an executive officer of the other party to the effect that

                                                                      ----------


           NEITHER THIS WARRANT NOR THE SHARES ISSUABLE UPON EXERCISE
          HEREOF HAVE BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933,
          AS AMENDED (THE "ACT"), OR THE SECURITIES LAWS OF ANY STATE.
          NEITHER THIS WARRANT NOR THE SHARES OF COMMON STOCK ISSUABLE
          UPON EXERCISE HEREOF MAY BE SOLD OR OTHERWISE TRANSFERRED IN
          THE ABSENCE OF REGISTRATION OR QUALIFICATION OR AN EXEMPTION
                         THEREFROM UNDER APPLICABLE LAW.

                          COMMON STOCK PURCHASE WARRANT
                          Void after November 13, 2000

                                              Warrant to Purchase 125,000 Shares
                                                 of Common Stock, $.01 par value
                                                      of Penn Octane Corporation

                         PENN OCTANE CORPORATION (POCC)

This  is  to  Certify  That,  FOR  VALUE  RECEIVED,

                           Van Moer Santerre & Company

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  November  __, 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),  125,000  shares  of  Common  Stock,  $.01  par value, of the Company (the
"Common  Stock")  at an exercise price of $1.25 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."

     15. 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

<PAGE>
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.

     16. 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.

     17. 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.

     18. 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 11 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.

<PAGE>
     19.  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.

     20. 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:

          1. pays a dividend  or makes a  distribution  on its  Common  Stock in
          shares of its Common Stock;

          2.  subdivides its  outstanding  shares of Common Stock into a greater
          number of shares;

          3.  combines  its  outstanding  shares of Common  Stock into a smaller
          number of shares;

          4. makes a  distribution  on its Common Stock in shares of its capital
          stock other than Common Stock; or

          5. 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.

                                       3
<PAGE>
               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  until  the
occurrence  of such  event by (i)  issuing  to the  Holder,  if this  Warrant is
exercised  after such record date,  the shares of Common Stock and other capital
stock of the Company,  if any,  issuable  upon such  exercise 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 in effect prior to such
adjustment,  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.  Whenever reference is made in Section 6(a) to the
        --------------------
issue of shares of Common  Stock,  the term  "Common  Stock"  shall  include any
equity securities of any class of the Company hereinafter authorized which shall
not be  limited  to a fixed sum or  percentage  in  respect  of the right of the
holders thereof to participate in dividends or  distributions of assets upon the
voluntary or involuntary liquidation, dissolution or winding up of the Company.

                                       4
<PAGE>
Subject  to  the  provisions  of Section 7 hereof, however, 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. 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.

     8. 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.

     9. Repurchase Right.  Notwithstanding any other provisions of this Warrant,
        ----------------
the Company  may, in the event  that,  after the date six months  after the date
hereof, the closing bid price, as reported on the NASDAQ SmallCap Market or such
other  exchange on which the Company's  Common Stock may then be quoted,  of the
Company's  Common Stock is greater  than or equal to 150% of the Exercise  Price
for five  consecutive  trading days, upon not less than five (5) 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 five (5) day  period,  the
Holder may  exercise  such  Warrant in  accordance  with the terms  hereof.  The
closing on such repurchase  shall occur on the date and at the time set forth in
such notice at the office of the Company in Redwood City,  California or at such
other  place as shall be  agreed  upon by the  Company  and the  Holder.  At the
Closing, the Company shall deliver to the Holder an amount equal to the purchase
price in immediately available funds and the Holder will deliver this Warrant to
the Company for cancellation.  To the extent any repurchase hereunder is of less
than all of the rights represented by this Warrant,  the Company will deliver to
the Holder a new Warrant covering the rights not so purchased.

                                       5
<PAGE>
     10. Determination by Board of Directors. All determinations by the Board of
         -----------------------------------
Directors of the Company  under the  provisions  of this Warrant will be made in
good faith with due regard to the interest of the Holder and in accordance  with
sound financial practices.

     11. Notice. All notices to the Holder shall be in writing,  and all notices
         ------
and certificates given to the Holder shall be sent registered or certified mail,
return receipt requested, to such Holder at his address appearing on the records
of the Company.

     12.  Replacement of Lost,  Stolen,  Destroyed or Mutilated  Warrants.  Upon
          ---------------------------------------------------------------
receipt of evidence  reasonably  satisfactory to the Company of the loss, theft,
destruction  or  mutilation  of this  Warrant and, in the case of any such loss,
theft or  destruction,  upon delivery of any indemnity  bond in such  reasonable
amount as the Company may determine in the case of any such mutilation, upon the
surrender of such  Warrant for  cancellation,  the Company at its expense,  will
execute  and  deliver,  in lieu of such lost,  stolen,  destroyed  or  mutilated
Warrant, a new Warrant of like tenor.

     13.  Number and Gender.  Whenever the singular  number is used herein,  the
          -----------------
same shall include the plural where  appropriate,  and words of any gender shall
include each other gender where appropriate.

     14.  Applicable  Law.  This Warrant  shall be governed by, and construed in
          ---------------
accordance  with,  the laws of the  State of New  York,  without  regard  to its
conflict of laws principles.

     -----------------------
upon  exercise  of the Warrants, plus any Common Stock issued or issuable to the
Purchaser  in  respect  of  the  Shares or Warrant Shares, pursuant to any stock
split, stock dividend, recapitalization, or similar event.  The Warrant is not a
Registrable  Security  hereunder.  As  to  any  Registrable  Securities,  such
securities  shall  cease  to  be  Registrable Securities when (i) a registration
statement  with  respect  to  the  sale  of  such  securities  shall have become
effective  under the Securities Act and such securities shall have been disposed
of pursuant to such effective registration statement, (ii) such securities shall
have  been  distributed  pursuant  to  Rule 144 or any similar provision then in
force, under the Securities Act, (iii) such securities shall have been otherwise
transferred,  new  certificates  or  other  evidences  of ownership for them not
bearing  a  legend  restricting  further  transfer  and  not subject to any stop
transfer  order  or  other restrictions on transfer shall have been delivered by
the  Company  and  subsequent  disposition  of such securities shall not require

<PAGE>
registration or qualification of such securities under the Securities Act or any
state  securities  laws then in force or (iv) the sale of such securities by the
holder  thereof shall no longer require registration under the Securities Act or
such  securities  shall  cease  to  be  outstanding.

     Registration  Expenses:  All reasonable expenses incurred by the Company in
     ----------------------
complying  with  Section  3  hereof, including all registration and filing fees,
printing  expenses,  fees and disbursements of counsel for the Company, and blue
sky  fees  and  expenses.

     Registration  Statement:  Any  registration  statement of the Company which
     ------------------------
covers  any  of  the  Registrable  Securities pursuant to the provisions of this
Agreement,  including  the  Prospectus,  amendments  and  supplements  to  such
registration  statement,  including post-effective amendments, all exhibits, and
all material incorporated by reference or deemed to be incorporated reference in
such  registration  statement.

     Restricted  Securities:  The  Shares  and  the Warrant Shares upon original
     -----------------------
issuance thereof, and at all times subsequent thereto, until, in the case of any
such  security,  it  is  no longer required to bear the legend set forth on such
security  pursuant  to  the  terms  of  the security, the Purchase Agreement and
applicable  law.

     Purchase  Agreement:  The  Agreement  by  and  among  the  Company  and the
     --------------------
Purchaser  pursuant  to  which  the  Shares  and  the  Warrant  were  issued.

     Rule  144:  Rule  144 under the Securities Act, as such Rule may be amended
     ----------
from  time  to  time, or any similar rule or regulation hereafter adopted by the
Commission  (excluding  Rule  144A).

2.   Securities  Subject  to  this  Agreement
     ----------------------------------------

The  securities  entitled  to the benefits of this Agreement are the Registrable
Securities.

3.   "Piggy-Back"  Registrations.
     ---------------------------

     (a) If at any time the  Company  shall  determine  to  register  any of its
Common  Stock under the  Securities  Act,  whether in  connection  with a public
offering by the Company, a public offering by shareholders,  or both, including,
without  limitation,  by means of any shelf  registration  pursuant  to Rule 415
under the  Securities  Act or any similar rule or  regulation,  but other than a
registration to implement an employee benefit or dividend reinvestment plan, the
Company shall promptly give written notice thereof to the Purchaser who shall be
a  registered  holder of  Registrable  Securities  and shall use its  reasonable
efforts to effect the registration  under the Securities Act of such Registrable
Securities as may be requested in a writing  delivered to the Company  within 30
days after such notice by the  Purchaser as well as to include such  Registrable
Securities in any notifications, registrations or qualifications under any state
securities  laws which shall be made or obtained with respect to the  securities
being registered by the Company; provided, however, that (a) any distribution of
                                 --------  -------
Registrable  Securities  pursu-ant to such registration  shall be managed by the
investment  banking firm, if any,  managing the  distribution  of the securities
being  offered by the  Company on the same terms as all other  securities  to be
registered,  and (b) the Company  shall not be required  under this Section 3 to
include Registrable  Securities in any registration of securities if the Company
shall have been advised by the investment  banking firm managing the offering of
the  securities  proposed  to be  registered  by the  Company or others that the
inclusion  of  Registrable  Securities  in  such  offering  would  substantially
interfere with the orderly sale of such  securities  which the Company or others
propose to register;  provided,  however, that in making any determination under
this  subparagraph (b) as to the inclusion of the Registrable  Securities in any

<PAGE>
such offering,  Registrable  Securities  shall be registered on a pro-rata basis
with any other  securities  as to which the  Company  has  granted or may in the
future grant registration  rights. All expenses of any registration and offering
of  Registrable  Securities  pursuant  to this  Section  3  (including,  without
limitation,  registration  fees  and  fees and  disbursements  of the  Company's
counsel)  shall be borne by the Company,  except that the Company shall not bear
underwrit-ing  discounts or commissions  attributable to Registrable Securities,
the fees of any separate  counsel for the holders of  Registrable  Securities or
related transfer taxes.

4.   Registration  Procedures.
     ------------------------

     (a) In connection with any registration  pursuant to Section 3 hereof,  the
Company will prepare and file with the SEC, a  Registration  Statement,  and any
amendments  and  supplements  thereto,  on any form for which the  Company  then
qualifies or which counsel for the Company shall deem  appropriate,  and use its
reasonable  efforts to cause such  Registration  Statement to become  effective;
provided that before filing with the SEC a Registration  Statement or prospectus
- --------
or any  amendments  or  supplements  thereto,  the  Company  will (i) furnish to
counsel  selected by the Purchaser  copies of all such documents  proposed to be
filed,  which documents will be subject to the review of such counsel,  and (ii)
notify the  Purchaser of any stop order issued or threatened by the SEC and take
all  reasonable  actions  required to prevent the entry of such stop order or to
remove it if entered. The Company will also (i) promptly notify the Purchaser of
the effectiveness of such Registration Statement,  (ii) furnish to the Purchaser
such number of copies of such  Registration  Statement,  and each  amendment and
supplement thereto,  the Prospectus included in such Registration  Statement and
such other  documents as the Purchaser  may  reasonably  request;  (iii) use its
reasonable efforts to register or qualify such securities to be registered under
such other  securities or blue sky laws of such  jurisdictions  as the Purchaser
reasonably  requests;  (iv)  use  its  reasonable  efforts  to  cause  all  such
securities to be registered  to be listed on each  securities  exchange on which
similar  securities  issued by the  Company  are then  listed,  and to provide a
transfer agent and registrar for such  securities to be registered no later than
the  effective  date  of  such  Registration  Statement;  (v)  enter  in to such
customary agreements (including an underwriting agreement in customary form) and
take all such other actions as the Lenders or the  underwriters  retained by the
Purchaser,  if any,  reasonably  request in order to expedite or facilitate  the
disposition   of  such   securities  to  be  registered,   including   customary
indemnification;  and (vi) otherwise use its  reasonable  efforts to comply with
all  applicable  rules and  regulations  of the SEC. The terms of this Section 4
shall not require the Company to qualify as a foreign corporation or as a dealer
in  securities  or to execute or file any general  consent to service of process
under the laws of any such jurisdiction where it is not so subject.

     (b) In connection with any effective  Registration Statement filed pursuant
to  this  Agreement,   the  Company  will   immediately   notify  the  Purchaser
participating in the distribution to which such  Registration  Statement relates
of the  happening of any event as a result of which the  prospectus  included in
such Registration  Statement  contains an untrue statement of a material fact or
omits to state any material fact  required to be stated  therein or necessary to
make the statements  therein not misleading in light of the  circumstances  then
existing, and will promptly prepare and furnish to the Purchaser a supplement or
amendment to such  prospectus so that such prospectus will not contain an 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 not  misleading in
light of the circumstances then existing.  Notwithstanding the foregoing, if the
Company  determines  in its  reasonable  business  judgment that an amendment or
supplement to any such prospectus  would interfere with any material  financing,
acquisition,  corporate reorganization,  or other material corporate transaction
or development  involving the Company, the Company may delay the preparation and
filing of such amendment or supplement for a period of up to 60 days in order to
complete or make a public announcement with respect to such material transaction
or  development  (it being  understood  that the Company  shall be  obligated to
extend  the  period  of time it is  required  to  maintain  in  effect  any such
Registration  Statement  to take  into  account  the  period  of time  that  the
Purchaser is unable to offer or sell  Registrable  Securities  by reason of this
Section 4(c)).


<PAGE>
5.   Holdback  Agreements.
     --------------------

     (a) Restrictions on Public Sale by Holders of Registrable Securities.  Each
         ----------------------------------------------------------------
holder of Registrable  Securities whose Registrable  Securities are covered by a
Registration  Statement filed pursuant to Section 3 hereof agrees,  if requested
by the managing  underwriters in an underwritten  offering (to the extent timely
notified in writing by the Company or the managing underwriters),  not to effect
any  public  sale or  distribution  of  securities  of the  Company of any class
included in such Registration  Statement,  including a sale pursuant to Rule 144
(except as part of such underwritten  offering),  during the 10-day period prior
to, and the 90-day period  beginning on, the effective date of any  Registration
Statement.

     (b) The foregoing  provisions  shall not apply to any holder of Registrable
Securities if such holder is prevented by applicable  statute or regulation from
entering into any such agreement;  provided, however, that any such holder shall
                                   -----------------
undertake in its request to participate in any such underwritten offering not to
effect any public sale or  distribution  of the class of Registrable  Securities
covered by such  Registration  Statement  (except  as part of such  underwritten
offering) during such period unless it has provided five (5) business days prior
written  notice of such sale or  distribution  to the  managing  underwriter  or
underwriters.

6.   Indemnification
     ---------------

     (a)  Indemnification  by Company.  The  Company  shall  indemnify  and hold
          ---------------------------
harmless,  to the full  extent  permitted  by law,  each  holder of  Registrable
Securities,  its  officers,  directors,  agents and  employees,  each person who
controls such holder  (within the meaning of Section 15 of the Securities Act or
Section  20 of the  Exchange  Act),  and  the  officers,  directors,  agents  or
employees of any such controlling person,  from and against all losses,  claims,
damages,  liabilities,  costs  (including,  without  limitation,  all reasonable
attorneys' fees) and expenses (collectively,  "Losses"), arising out of or based
upon any untrue  statement  of a material  fact  contained  in any  Registration
Statement, Prospectus or preliminary prospectus, or arising out of or based upon
any omission of 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 (in the case of any Prospectus) not misleading,  except insofar as the same
are based  solely upon  information  furnished to the Company by such holder for
use therein; provided, however, that the Company shall not be liable in any such
             -----------------
case to the extent  that any such Loss  arises out of or is based upon an untrue
statement or omission  made in any  preliminary  prospectus or Prospectus if (i)
such holder  failed to send or deliver a copy of the  Prospectus  or  Prospectus
supplement with or prior to the delivery of written  confirmation of the sale of
Registrable  Securities and (ii) the Prospectus or Prospectus  supplement  would
have corrected such untrue statement or omission.

     (b) Indemnification by Holder of Registrable Securities. In connection with
         ---------------------------------------------------
any  Registration  Statement  in which a holder  of  Registrable  Securities  is
participating,  such  holder of  Registrable  Securities  shall  furnish  to the
Company in writing such  information as the Company may  reasonably  request for
use in connection with any Registration Statement or Prospectus.  Each holder of
Registrable  Securities  shall  indemnify and hold harmless,  to the full extent
permitted  by  law,  the  Company,  and  its  officers,  directors,  agents  and
employees,  each person who controls the Company  (within the meaning of Section
15 of the  Securities  Act or Section 20 of the Exchange  Act) and the officers,
directors,  agents or employees of any such controlling person, from and against
all Losses arising out of or based upon any untrue  statement of a material fact
contained in any Registration  Statement,  Prospectus or preliminary prospectus,
or arising out of or based upon any omission of a material  fact  required to be

<PAGE>
stated  therein  or  necessary  to make the  statements  therein in light of the
circumstances  under  which they were made (in the case of any  Prospectus)  not
misleading, to the extent, but only to the extent, that such untrue statement or
omission is contained in any  information so furnished in writing by such holder
to the Company for use in such Registration Statement, Prospectus or preliminary
prospectus.  Such indemnity shall remain in full force and effect  regardless of
any  investigation  made by or on behalf of the Company or any holder and any of
their respective directors,  officers,  agents, employees or controlling persons
(within  the  meaning of Section 15 of the  Securities  Act or Section 20 of the
Exchange Act) and shall survive the transfer of such securities by such holder.

     (c) Conduct of  Indemnification  Proceedings.  If any action or  proceeding
         ----------------------------------------
(including any  governmental  investigation  or inquiry) shall be brought or any
claim shall be asserted  against any person entitled to indemnity  hereunder (an
"indemnified  party"),  such  indemnified  party shall promptly notify the party
from which such indemnity is sought (the "indemnifying  party") in writing,  and
the  indemnifying  party  shall  assume  the  defense  thereof,   including  the
employment of counsel  reasonably  satisfactory to the indemnified party and the
payment  of all  fees and  expenses  incurred  in  connection  with the  defense
thereof. All such fees and expenses (including any fees and expenses incurred in
connection with  investigating or preparing to defend such action or proceeding)
incurred by the indemnified  party,  shall be paid to the indemnified  party, as
incurred,  within 20 days of written notice thereof to the  indemnifying  party;
provided,  however, that if, in accordance with this Section 6, the indemnifying
- ------------------
party is not liable to the  indemnified  party,  such fees and expenses shall be
returned  promptly to the indemnifying  party. Any such indemnified  party shall
have  the  right  to  employ  separate  counsel  in any  such  action,  claim or
proceeding and to participate in the defense thereof,  but the fees and expenses
of such counsel  shall be the expense of such  indemnified  party unless (a) the
indemnifying  party  has  agreed  to  pay  such  fees  and  expenses,   (b)  the
indemnifying  party  shall have  failed  promptly  to assume the defense of such
action, claim or proceeding and to employ counsel reasonably satisfactory to the
indemnified  party in any such  action,  claim or  proceeding,  or (c) the named
parties  to any  such  action,  claim or  proceeding  (including  any  impleaded
parties)  include both such indemnified  party and the  indemnifying  party, and
such indemnified  party shall have been advised by counsel that there may be one
or more legal defenses available to it which are different from or additional to
those available to the  indemnifying  party (in which case, if such  indemnified
party  notifies  the  indemnifying  party in  writing  that it  elects to employ
separate  counsel at the expense of the  indemnifying  party,  the  indemnifying
party  shall not have the right to assume the defense of such  action,  claim or
proceeding on behalf of such indemnified  party, it being  understood,  however,
that the  indemnifying  party shall not, in connection with any one such action,
claim or proceeding or separate but  substantially  similar or related  actions,
claims or proceedings in the same  jurisdiction  arising out of the same general
allegations or circumstances,  be liable for the reasonable fees and expenses of
more than one  separate  firm of  attorneys  (together  with  appropriate  local
counsel) at any time for all such indemnified parties,  unless in the opinion of
counsel for such indemnified party a conflict of interest may exist between such
indemnified party and any other of such indemnified parties with respect to such
action,  claim or  proceeding,  in which event the  indemnifying  party shall be
obligated to pay the fees and expenses of such additional  counsel or counsels).
No  indemnifying  party will  consent to entry of any judgment or enter into any
settlement which does not include as an  unconditional  term thereof the release
of such  indemnified  party  from all  liability  in  respect  to such  claim or
litigation  without the written  consent (which consent will not be unreasonably
withheld) of the indemnified  party. No indemnified party shall consent to entry
of any judgment or enter into any set-tlement without the written consent (which
consent will not be unreasonably  withheld) of the indemnifying party from which
indemnity or contribution is sought.

     (d)  Contribution.  If the  indemnification  provided for in this Section 6
          ------------
from the indemnifying  party is unavailable to an in-demnified  party in respect
of any Losses,  then each applicable  indemnifying party in lieu of indemnifying
such indemnified  party hereunder shall contribute to the amount paid or payable
by such indemnified  party as a result of such Losses,  in such proportion as is
appropriate  to  reflect  the  relative  fault  of the  indemnifying  party  and

<PAGE>
indemnified party in connection with the actions,  statements or omissions which
resulted in such Losses as well as any other relevant equitable  considerations.
The relative fault of such indemnifying party and the indemnified party shall be
determined by reference to, among other things,  whether any action in question,
including  any untrue  statement  of a material  fact or  omission of a material
fact,  has been taken or made by, or relates to  information  supplied  by, such
indemnifying  party or  indemnified  party,  and the parties'  relative  intent,
knowledge,  access to  information  and  opportunity  to correct or prevent such
action, statement or omission. The amount paid or payable by a party as a result
of any Losses shall be deemed to include,  subject to the  limitations set forth
in Section 6(c), any legal or other fees or expenses reasonably incurred by such
party in connection with any action, suit, claim, investigation or proceeding.

     The  parties  hereto  agree  that  it  would  not  be just and equitable if
contribution  pursuant  to  this  Section  6(d)  were  determined  by  pro  rata
allocation or by any other method of allocation which does not take into account
the equitable considerations referred to in the immediately preceding paragraph.
No  person guilty of fraudulent misrepresentation (within the meaning of Section
11(f)  of  the Securities Act) shall be entitled to contribution from any person
who  was  not  guilty  of  such  fraudulent  misrepresentation.

7.   Rule  144
     ---------

     The  Company  shall  file  the reports required to be filed by it under the
Securities Act and the Exchange Act and the rules and regulations adopted by the
Commission  thereunder,  and  will  take  such  further  action as any holder of
Registrable  Securities  may reasonably request, all to the extent required from
time  to  time  to  enable  such  holder  to sell Registrable Securities without
registration  under  the  Securities  Act within the limitation of the exemption
provided  by  Rule  144  or  Rule  144A.  Upon  the  request  of  any  holder of
Registrable  Securities,  the  Company  shall  deliver  to such holder a written
statement  as  to  whether  the  Company  has complied with such information and
requirements.  Notwithstanding the foregoing, nothing in this Section 7 shall be
deemed  to  require  the  Company  to  register  any of its securities under any
section  of  the  Exchange  Act.

8.   Underwritten  Registrations
     ---------------------------

     If  any of the Registrable Securities covered by any registration are to be
sold  in  an  underwritten offering, the investment banker or investment bankers
and  manager  or  managers that will administer the offering will be selected by
the  Company.  No  holder  of  Registrable  Securities  may  participate  in any
underwritten  registration  hereunder unless such holder (i) agrees to sell such
holder's  Registrable  Securities  on  the  basis  provided  in the underwriting
arrangements  approved  by  the  Company,  and  (ii)  completes and executes all
questionnaires,  powers  of  attorney,  indemnities, underwriting agreements and
other  documents  required  under  the  terms of such underwriting arrangements.

9.   Miscellaneous
     -------------

     (a) Amendments and Waivers. The provisions of this Agreement, including the
         ----------------------
provisions of this sentence, may not be amended,  modified or supplemented,  and
waivers or consents to departures  from the  provisions  hereof may not be given
unless the Company obtains the written consent of holders of at least a majority
of the then  outstanding  Registrable  Securities  affected  by such  amendment,
modification or supplement.  Notwithstanding the foregoing,  a waiver or consent
to depart from the  provisions  hereof with  respect to a matter  which  relates
exclusively to the rights of holders of Registrable Securities whose securi-ties
are being sold pursuant to a Registration  Statement and which does not directly
or  indirectly  affect the rights of holders  of  Registrable  Securities  whose

<PAGE>
securities  are not being sold  pursuant to such  Registration  Statement may be
given by holders of a majority of the Registrable  Securities being sold by such
holders.

     (b) Notices. All notices and other communications provided for or permitted
         -------
hereunder  shall be made in writing  by  hand-delivery,  registered  first-class
mail,  next  day  air  courier,  telex,  or  telecopy:  (i)  if to a  holder  of
Registrable Securities,  at the most current address given by such holder to the
Company in accordance  with the  provisions of this Section 9(b),  which address
initially is, with respect to the Purchaser, the address set forth in Section __
of the  Purchase  Agreement;  and  (ii)  if to  the  Company,  at  900  Veterans
Boulevard,  Suite 240, Redwood City California 94063, attention:  Secretary, and
thereafter at such other  address,  notice of which is given in accordance  with
the provisions of this Section 8(b).

     All  such  notices  and  communications  shall  be deemed to have been duly
given:  when delivered by hand, if personally delivered; two business days after
being  deposited in the mail, postage prepaid, if mailed; one business day after
being  sent  by  next  day air courier; when answered back, if telexed; and when
receipt  acknowledged,  if  telecopied.

     (c)  Transfer of  Registration  Rights.  The rights  granted to the holders
          ---------------------------------
pursuant to this  Agreement to cause the Company to register  securities may not
be assigned or  otherwise  transferred  in any way other than to an Affiliate of
the holder to whom the holder has transferred all or any part of the Warrant.

     (d)  Counterparts.  This  Agreement  may  be  executed  in  any  number  of
          ------------
counterparts  by the parties  hereto,  each of which when so  executed  shall be
deemed to be an original and all of which taken  together  shall  constitute one
and the same agreement.

     (e)  Headings.  The  headings  in this  Agreement  are for  convenience  of
          --------
reference only and shall not limit or otherwise affect the meaning hereof.

     (f)  Governing  Law. This  Agreement  shall be governed by and construed in
          --------------
accordance  with the laws of the State of New York without  regard to principles
of conflict of laws.

     (g) Severability.  If any term, provision,  covenant or restriction of this
         ------------
Agreement is held by a court of competent  jurisdiction  to be invalid,  void or
unenforceable,   the   remainder  of  the  terms,   provisions,   covenants  and
restrictions set forth herein shall remain in full force and effect and shall in
no way be affected,  impaired or  invalidated,  and the parties hereto shall use
their best efforts to find and employ an  alternative  means to achieve the same
or substantially the same result as that  contemplated by such term,  provision,
covenant  or  restriction.  It is  hereby  stipulated  and  declared  to be  the
intention of the parties  that they would have  executed  the  remaining  terms,
provisions,  covenants and restrictions  without including any of such which may
be hereafter declared invalid, void or unenforceable.

     (h) Entire  Agreement.  This  Agreement  is intended by the parties to be a
         -----------------
final  expression of their  agreement and a complete and exclusive  statement of
the agreement and  understanding of the parties hereto in respect of the subject
matter contained  herein.  There are no restrictions,  promises,  warranties nor
undertakings,  other than those set forth or referred to herein with  respect to
the  registration  rights  granted by the Company with respect to the securities
sold pursuant to the Purchase  Agreement.  This  Agreement  supersedes all prior
agreements and  understandings  between the parties with respect to such subject
matter.

<PAGE>
     (i) Attorneys'  Fees. If any action or proceeding is brought to enforce any
         ----------------
provision of this Agreement,  or where any provision  hereof is validly asserted
as a defense,  the  successful  party shall be  entitled  to recover  reasonable
attorneys'  fees in addition to its costs and expenses  and any other  available
remedy.

     IN WITNESS WHEREOF, the parties have executed this agreement as of November
__,  1998.

                                                 of Common Stock, $.01 par value
                                                      of Penn Octane Corporation

This  is  to  Certify  That,  FOR  VALUE  RECEIVED,

                           Van Moer Santerre & Company

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  November  __, 2000 (or, if such date is not a Business Day in Redwood

     15.     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.

     16.     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.

     17.     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.

     18.     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 11 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.

     19.     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.

     20.     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:

          1.     pays  a dividend or makes a distribution on its Common Stock in
shares  of  its  Common  Stock;

          2.     subdivides  its  outstanding  shares  of  Common  Stock  into a
greater  number  of  shares;

          3.     combines  its outstanding shares of Common Stock into a smaller
number  of  shares;

          4.     makes  a  distribution  on  its  Common  Stock in shares of its
capital  stock  other  than  Common  Stock;  or

          5.     issues  by  reclassification  of its Common Stock any shares of
its  capital  stock;

                                        3
<PAGE>
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 until the
occurrence  of  such  event  by  (i)  issuing  to the Holder, if this Warrant is
exercised  after  such record date, the shares of Common Stock and other capital

                                        4
<PAGE>
stock  of  the  Company,  if any, issuable upon such exercise 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 in effect prior to such
adjustment,  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.  Whenever reference is made in Section 6(a) to
            --------------------
the  issue  of shares of Common Stock, the term "Common Stock" shall include any
equity securities of any class of the Company hereinafter authorized which shall
not  be  limited  to  a  fixed  sum or percentage in respect of the right of the
holders  thereof to participate in dividends or distributions of assets upon the
voluntary  or involuntary liquidation, dissolution or winding up of the Company.
Subject  to  the  provisions  of Section 7 hereof, however, 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.     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

                                        5
<PAGE>
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.

     8.     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.

     9.     Repurchase  Right.  Notwithstanding  any  other  provisions  of this
            -----------------
Warrant, the Company may, in the event that, after the date six months after the
date hereof, the closing bid price, as reported on the NASDAQ SmallCap Market or
such  other  exchange on which the Company's Common Stock may then be quoted, of
the  Company's  Common  Stock  is  greater than or equal to 150% of the Exercise
Price  for  five  consecutive  trading  days,  upon not less than five (5) 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 five (5) day period, the
Holder  may  exercise  such  Warrant  in  accordance with the terms hereof.  The
closing  on such repurchase shall occur on the date and at the time set forth in
such  notice at the office of the Company in Redwood City, California or at such
other  place  as  shall  be  agreed  upon by the Company and the Holder.  At the
Closing, the Company shall deliver to the Holder an amount equal to the purchase
price in immediately available funds and the Holder will deliver this Warrant to
the Company for cancellation.  To the extent any repurchase hereunder is of less
than  all of the rights represented by this Warrant, the Company will deliver to
the  Holder  a  new  Warrant  covering  the  rights  not  so  purchased.

     10.     Determination  by  Board  of  Directors.  All determinations by the
             ---------------------------------------
Board  of  Directors of the Company under the provisions of this Warrant will be
made  in  good  faith  with  due  regard  to  the  interest of the Holder and in
accordance  with  sound  financial  practices.

     11.     Notice.  All  notices  to  the  Holder shall be in writing, and all
             ------
notices  and  certificates  given  to  the  Holder  shall  be sent registered or

                                        6
<PAGE>
certified  mail,  return  receipt  requested,  to  such  Holder  at  his address
appearing  on  the  records  of  the  Company.

     12.     Replacement of Lost, Stolen, Destroyed or Mutilated Warrants.  Upon
             ------------------------------------------------------------
receipt  of  evidence reasonably satisfactory to the Company of the loss, theft,
destruction  or  mutilation  of  this Warrant and, in the case of any such loss,
theft  or  destruction,  upon  delivery of any indemnity bond in such reasonable
amount as the Company may determine in the case of any such mutilation, upon the
surrender  of  such  Warrant  for cancellation, the Company at its expense, will
execute  and  deliver,  in  lieu  of  such  lost, stolen, destroyed or mutilated
Warrant,  a  new  Warrant  of  like  tenor.

     13.     Number  and  Gender.  Whenever  the singular number is used herein,
             -------------------
the  same  shall  include  the plural where appropriate, and words of any gender
shall  include  each  other  gender  where  appropriate.

     14.     Applicable  Law.  This  Warrant shall be governed by, and construed
             ---------------
in  accordance  with,  the  laws of the State of New York, without regard to its
conflict  of  laws  principles.

material fact or omit to state any material fact  necessary in order to make the
facts stated  therein,  in light of the  circumstances  in which such statements
were made, not misleading.

     5.     Representations  and  Warranties  of  the  Purchaser.  The Purchaser
            ----------------------------------------------------
represents  and  warrants  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 its 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.

                                        4
<PAGE>
               (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 its advisors (if any) have received all
information and data which the Purchaser and its 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 Warrant and that resale of the
Shares,  the  Warrant  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 Shares, the
Warrant  and  Warrant  Shares,  as  the  case  may  be.

                                        5

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

               (i)     The  Purchaser is acquiring the Securities and any shares
of  Common  Stock  purchased  upon  exercise  of  the Warrant solely for its own
account,  for  investment  purposes,  and  not  with a view to, or for resale in
connection  with,  any distribution of the Shares, the Warrant or such shares of
Common  Stock.  The  Purchaser  understands that neither the Shares, the Warrant
nor  such  underlying  shares  of  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 Shares, the Warrant
and  such  underlying  shares  of  Common  Stock  are  or will be upon issurance
"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

                                        6
<PAGE>
Act,  the  Purchaser may dispose of the Shares, Warrant and underlying shares of
Common  Stock  only  in  accordance  with  the  provisions of Rule 144 under the
Securities  Act,  to  the  extent  available, or in other transactions which are
exempt  from  registration under the Securities Act, in which the transferee may
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 Shares, the Warrant 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 Shares, the Warrant and
any  certificate(s)  representing shares of Common Stock issued upon exercise of
the  Warrant  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)     In  no  event  shall  any  sale,  assignment,  pledge or
transfer  of  the  Shares,  the  Warrant  or such underlying Common Stock by the
Purchaser  to  a transferee give rise to rights of any such transferee under the
Registration  Rights  Agreement.

     6.     Conditions  to  Obligations  of  Purchaser  and  the  Company.  The
            -------------------------------------------------------------
obligations  of  the  Purchaser to purchase and pay for the 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  and  the  Purchaser  shall  each have received a
certificate  from  the General Partner of the Purchaser and an executive officer
of  the  Company,  respectively,  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.     Board  of Directors.     The Company agrees that the Purchaser shall
            --------------------
have  one  (1) seat on the Board of Directors.  The Company will cause the Board
of  Directors to elect the Purchaser's nominee to the Board of Directors as soon
as  practicable  after  the  purchase  and sale of the Securities is consummated
hereunder.  At  each  annual  stockholders  meeting  of  the  Company  after the
purchase  and  sale of the Securities is consummated hereunder, the Company will
cause  the  Purchaser's designee to be nominated as a part of management's slate
of  nominees  for election as directors.  The Company shall use its best efforts
to  ensure  the election of the Purchaser's nominee as a director of the Company
at  each  such  annual  meeting  of  the  stockholders  of  the  Company.

     8.     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.

     9.     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 the Purchaser without the prior written
consent  of  the  other party, which consent shall not be unreasonably withheld.

     10.     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.

     11.     Section  and  Other  Headings.  The  section  and  other  headings
             -----------------------------

3.   Registration  Rights.
     ---------------------

     (a)  Demand Registration.
          -------------------

          (i)  The Investor,  or if the Investor  shall have assigned any of its
               rights to any permitted  successors  and assigns  hereunder,  the
               holders of a majority of the  Registrable  Securities may request
               that the Company register, and upon such request the Company will
               register,  all or part of the Registrable Securities (the "Demand
               Registration"),  subject  to the  terms  and  conditions  of this
               Agreement. The holders of Registrable Securities will be entitled
               to  request  one  Demand   Registration  which  may  be  a  shelf
               registration  relating to sales of proposed to be made by holders
               of  Registrable  Securities  pursuant to Rule 415 of the SEC. The
               request (a  "Registration  Request") for the Demand  Registration
               shall specify (a) the approximate number of shares of Registrable
               Securities

                                        2
<PAGE>
               requested  to be  registered  (but not less  than a  majority  of
               shares of the then  outstanding  number of shares of  Registrable
               Securities),  and (b) the intended method of distribution of such
               shares.  Within  ten  days  after  the  date of  sending  of such
               request,  the Company will give written  notice of such requested
               registration  to all other holders of  Registrable  of Securities
               and will include in such Registrable  Securities which holders of
               Registrable  Securities  request  the  Company  to  include  such
               registration  by written notice given to the Company with 15 days
               after the date of sending of the Company's notice.

          (ii) A registration  will count as the Demand  Registration if (a) the
               holders of  Registrable  Securities are able to register and sell
               at  least  seventy-five  percent  of the  Registrable  Securities
               requested  to  be  included  in  such   registration   or  (b)  a
               registration  statement  relating  to a  Demand  Registration  is
               prepared by the Company but prior to or after filing is withdrawn
               or  abandoned  at the request of the  holders of the  Registrable
               Securities to be covered by such  registration  statement  (other
               than as a result of a material  adverse  change to the Company or
               following  a  postponement  by the  Company  pursuant  to Section
               4(b)).

          (iii)The  Company may  include in any Demand  Registration  securities
               other than shares of Registrable  Securities and securities to be
               registered for offering and sale on behalf of the Company ("Other
               Securities"),  subject to compliance  with the provisions of this
               Section in the event any  limitation  is imposed on the number of
               securities  that may be  included  in such  registration.  If the
               managing  underwriter(s)  advise the  Company in writing  that in
               their opinion the number of shares of Registrable  Securities and
               Other Securities  desired to be included in such offering exceeds
               the  number  of  shares  of  Registrable   Securities  and  Other
               Securities,  if any,  which can be sold in an  orderly  manner in
               such offering within a price range acceptable to the holders of a
               majority  of  the  shares  of  Registrable  Securities  initially
               requesting  registration,   the  Company  will  include  in  such
               registration, prior to the inclusion of any Other Securities, the
               number  of  shares  of  Registrable  Securities  requested  to be
               included which in the opinion of such underwriters can be sold in
               an  orderly  manner  within  the  price  range of such  offering,
               allocated pro rata among the  respective  holders  thereof on the
               basis of the  number of shares of  Registrable  Securities  which
               each such  holder has  requested  the  Company to include in such
               registration.

          (iv) Selection of Underwriter. The holders of a majority of the shares
               ------------------------
               of Registrable  Securities to be included in a registration  will
               have the right to  designate  an  underwriter  to  co-manage  the
               offering being registered under the Demand registration,  subject
               to the Company's approval which will not be

                                        3
<PAGE>
               unreasonably  withheld or delayed. The Company will designate the
               lead-managing underwriter of the offering.

     (b)  "Piggy-Back" Registrations.
          --------------------------

          If  at  any  time  the  Company shall determine to register any of its
Common  Stock  under  the  Securities  Act,  whether in connection with a public
offering  by the Company, a public offering by shareholders, or both, including,
without  limitation,  by  means  of  any shelf registration pursuant to Rule 415
under  the  Securities  Act  or any similar rule or regulation, but other than a
Demand  Registration  or  a  registration  to  implement  an employee benefit or
dividend  reinvestment  plan,  the  Company  shall  promptly give written notice
thereof  to  the  Investor  who shall be the registered holder(s) of Registrable
Securities and shall use its reasonable efforts to effect the registration under
the  Securities  Act  of  such  Registrable  Securities as may be requested in a
writing  delivered  to  the  Company  within  30  days  after such notice by the
Investor as well as to include such Registrable Securities in any notifications,
registrations  or  qualifications under any state securities laws which shall be
made or obtained with respect to the securities being registered by the Company;
provided, however, that (a) any distribution of Registrable Securities pursu-ant
- --------  -------
to  such  registration  shall be managed by the investment banking firm, if any,
managing  the distribution of the securities being offered by the Company on the
same  terms  as all other securities to be registered, and (b) the Company shall
not be required under this Section 3(b) to include Registrable Securities in any
registration  of  securities  if  the  Company  shall  have  been advised by the
investment  banking  firm managing the offering of the securities proposed to be
registered by the Company or others that the inclusion of Registrable Securities
in  such  offering  would  substantially interfere with the orderly sale of such
securities  which  the Company or others propose to register; provided, however,
that in making any determination under this subparagraph (b) as to the inclusion
of the Registrable Securities in any such offering, Registrable Securities shall
be  registered  on  a  pro-rata  basis with any other securities as to which the
Company  has  granted  or  may  in  the  future  grant  registration  rights.

     (c)  Registration Expenses.
          ----------------------

          All  expenses  of  any  registration  and  offering  of  Registrable
Securities  pursuant  to  this  Section  3  (including,  without  limitation,
registration  fees, and disbursements of the Company's counsel, fees for listing
the  Registrable  Securities  on any exchange on which similar securities of the
Company  are  listed  for  trading  or on the NASDAQ/AMEX Stock Market) shall be
borne  by  the  Company  provided,  however,  that  the  expenses  of any Demand
Registration made within one year of the date of this Agreement shall be paid by
the  holders of the Registrable Securities.  The Company shall pay underwrit-ing
discounts  or  commissions  payable  with respect to the sale of the Registrable
Securities,  the  fees and disbursements of the separate counsel for the holders
of  Registrable Securities and related transfer taxes in an aggregate amount not
to  exceed  $20,000.

4.   Registration Procedures.
     ------------------------

     (a) In connection with any registration  pursuant to Section 3 hereof,  the
Company will prepare and file with the SEC, a  Registration  Statement,  and any
amendments  and  supplements  thereto,  on any form for which the  Company  then
qualifies or which counsel for the Company shall deem  appropriate,  and use its
reasonable  best  efforts  to  cause  such  Registration   Statement  to  become
effective;  provided that before filing with the SEC a Registration Statement or
            --------
prospectus  or any  amendments  or  supplements  thereto,  the Company  will (i)
furnish to the Investor and counsel  selected by the Investor copies of all such
documents  proposed to be filed,  which  documents will be subject to the review
and comment by the Investor and such  counsel,  and (ii) notify the Investors of
any stop order issued or threatened by the SEC and take all  reasonable  actions
required to prevent the entry of such stop order or to remove it if entered. The
Company will also (i) promptly notify the Investor of the  effectiveness of such
Registration  Statement,  (ii) furnish to the Investor  such number of copies of
such  Registration  Statement,  and each amendment and supplement  thereto,  the
Prospectus  included in such Registration  Statement and such other documents as
the Investor may reasonably  request;  (iii) use its reasonable  best efforts to
register or qualify such securities to be registered under such other securities
or blue sky laws of such  jurisdictions  as any Purchaser  reasonably  requests;
(iv) use its  reasonable  best  efforts  to  cause  all  such  securities  to be
registered to be listed on each securities  exchange on which similar securities
issued by the Company are then  listed for trading or on the  NASDAQ/AMEX  Stock
market,  and to provide a transfer agent and registrar for such securities to be
registered no later than the effective date of such Registration Statement;  (v)
enter in to such customary  agreements  (including an underwriting  agreement in
customary  form)  and  take  all  such  other  actions  as the  Investor  or the
underwriters  retained by the Investor,  if any,  reasonably request in order to
expedite or facilitate  the  disposition  of such  securities to be  registered,
including  customary  indemnification;  and (vi)  otherwise  use its  reasonable
efforts to comply with all applicable  rules and  regulations of the SEC and the
states and make available to the Investor as soon as reasonably practicable (but
not more than  eighteen  months) after the  effective  date of the  registration
Statement,  an earnings statement that satisfies the provisions of Section 11(a)
of the  Securities  Act and the rules of the SEC  thereunder.  The Company shall
take all other actions reasonably  necessary or advisable to enable the Investor
to consummate the  disposition  of any  Registrable  Securities  pursuant to any
registration  Statement and to comply with the  Securities  Act and the Exchange
Act in connection  with any offer and sale of any  Registrable  Securities.  The
terms of this  Section 4 shall not  require  the Company to qualify as a foreign
corporation  or as a dealer in  securities  or to  execute  or file any  general
consent to service of process under the laws of any such  jurisdiction  where it
is not so subject.

     (b) In connection with any effective  Registration Statement filed pursuant
to  this  Agreement,   the  Company  will  immediately  notify  the  holders  of
Registrable  Securities registered pursuant to the Registration Statement of the
happening  of any event as a result of which the  Registration  Statement or any
Prospectus contains an untrue statement of a material fact or omits to state any
material fact required to be stated  therein or necessary to make the statements
therein not misleading in light of the  circumstances  then  existing,  and will
promptly prepare and furnish to the holders of Registrable Securities a

                                        5
<PAGE>
supplement or amendment to such prospectus so that the Registration Statement or
such  Prospectus will not contain an 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  not  misleading  in  light  of  the circumstances then
existing.  Notwithstanding  the  foregoing,  if  the  Company  determines in its
reasonable business judgment that an amendment or supplement to the Registration
Statement  or  any  such Prospectus would interfere with any material financing,
acquisition,  corporate  reorganization, or other material corporate transaction
or  development involving the Company, the Company may delay the preparation and
filing  of  such  amendment  or  supplement for a period of up to 60 days in the
aggregate  in  order  to  complete or make a public announcement with respect to
such  material  transaction or development (it being understood that the Company
shall  be  obligated  to extend the period of time it is required to maintain in
effect  any  such Registration Statement to take into account the period of time
that  such  holders  of  Registrable  Securities  are  unable  to  offer or sell
Registrable  Securities  by  reason  of  this  Section  4(c)).

5.   Holdback  Agreements.
     ---------------------

     (a)     Restrictions  on  Public Sale by Holders of Registrable Securities.
             ------------------------------------------------------------------
Each  holder  of Registrable Securities whose Registrable Securities are covered
by  a  Registration  Statement  filed  pursuant  to  Section 3 hereof agrees, if
requested  by  the  managing  underwriters  in  an underwritten offering (to the
extent  timely notified in writing by the Company or the managing underwriters),
not  to  effect  any public sale or distribution of securities of the Company of
any  class included in such Registration Statement, including a sale pursuant to
Rule  144  (except  as  part  of  such underwritten offering), during the 10-day
period  prior  to, and the 90-day period beginning on, the effective date of any
Registration  Statement.

     (b)     The  foregoing  provisions  shall  not  apply  to  any  holder  of
Registrable  Securities  if  such  holder  is prevented by applicable statute or
regulation  from  entering  into any such agreement; provided, however, that any
                                                     -----------------
such  holder  shall  undertake  in  its  request  to  participate  in  any  such
underwritten offering not to effect any public sale or distribution of the class
of Registrable Securities covered by such Registration Statement (except as part
of  such  underwritten  offering) during such period unless it has provided five
(5)  business  days  prior  written  notice  of such sale or distribution to the
managing  underwriter  or  underwriters.

6.   Indemnification
     ---------------

     (a)     Indemnification  by  Company.  The Company shall indemnify and hold
             ----------------------------
harmless,  to  the  full  extent  permitted  by  law, each holder of Registrable
Securities,  its  officers,  directors,  agents  and  employees, each person who
controls  such holder (within the meaning of Section 15 of the Securities Act or
Section  20  of the Exchange Act), and the partners, officers, directors, agents
or  employees  of  any  such  controlling  person,  from and against all losses,
claims,  damages,  liabilities,  costs  (including,  without  limitation,  all
reasonable  attorneys'  fees) and expenses (collectively, "Losses"), arising out
of  or  based  upon  any  untrue  statement  of a material fact contained in any
Registration  Statement, Prospectus or preliminary prospectus, or arising out of

                                        6
<PAGE>
or  based  upon any omission of 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  (in  the case of any Prospectus) not misleading, except
insofar  as  the same are based solely upon information furnished to the Company
by such holder for use therein; provided, however, that the Company shall not be
                                -----------------
liable  in  any  such  case to the extent that any such Loss arises out of or is
based upon an untrue statement or omission made in any preliminary prospectus or
Prospectus if (i) such holder failed to send or deliver a copy of the Prospectus
or  Prospectus  supplement with or prior to the delivery of written confirmation
of  the  sale  of  Registrable  Securities and (ii) the Prospectus or Prospectus
supplement  would  have  corrected  such  untrue  statement  or  omission.

     (b)     Indemnification by Holder of Registrable Securities.  In connection
             ---------------------------------------------------
with  any  Registration Statement in which a holder of Registrable Securities is
participating,  such  holder  of  Registrable  Securities  shall  furnish to the
Company  in  writing  such  information  concerning such holder and its proposed
disposition  of  Registrable  Securities  pursuant  to  such registration as the
Company  may  reasonably  request  for  use  in connection with any Registration
Statement  or  Prospectus.  Each  Investor shall indemnify and hold harmless, to
the  full  extent  permitted  by  law, the Company, and its officers, directors,
agents  and  employees, each person who controls the Company (within the meaning
of  Section  15 of the Securities Act or Section 20 of the Exchange Act) and the
officers,  directors,  agents  or employees of any such controlling person, from
and  against  all  Losses arising out of or based upon any untrue statement of a
material fact contained in any Registration Statement, Prospectus or preliminary
prospectus,  or  arising  out  of  or based upon any omission of 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 (in the case of any
Prospectus)  not  misleading,  to  the extent, but only to the extent, that such
untrue  statement  or  omission  is contained in any information so furnished in
writing  by  such  holder to the Company for use in such Registration Statement,
Prospectus or preliminary prospectus.  Such indemnity shall remain in full force
and  effect  regardless of any investigation made by or on behalf of the Company
or any holder and any of their respective directors, officers, agents, employees
or  controlling  persons (within the meaning of Section 15 of the Securities Act
or  Section  20  of  the  Exchange  Act)  and shall survive the transfer of such
securities  by  such  holder.

     (c)     Conduct  of  Indemnification  Proceedings.  If  any  action  or
             ------------------------------------------
proceeding  (including  any  governmental  investigation  or  inquiry)  shall be
brought  or any claim shall be asserted against any person entitled to indemnity
hereunder (an "indemnified party"), such indemnified party shall promptly notify
the  party  from  which  such  indemnity is sought (the "indemnifying party") in
writing,  and the indemnifying party shall assume the defense thereof, including
the  employment  of counsel reasonably satisfactory to the indemnified party and
the  payment  of  all  fees and expenses incurred in connection with the defense
thereof.  All  such  fees and expenses (including any fees and expenses incurred
in  connection  with  investigating  or  preparing  to  defend  such  action  or
proceeding)  incurred by the indemnified party, shall be paid to the indemnified
party, as incurred, within 20 days of written notice thereof to the indemnifying
party;  provided,  however,  that  if,  in  accordance  with this Section 6, the
        ------------------
indemnifying  party  is  not  liable  to  the  indemnified  party, such fees and
expenses  shall  be  returned  promptly  to  the  indemnifying  party.  Any such
indemnified  party  shall  have the right to employ separate counsel in any such
action,  claim  or proceeding and to participate in the defense thereof, but the

                                        7
<PAGE>
fees and expenses of such counsel shall be the expense of such indemnified party
unless  (a) the indemnifying party has agreed to pay such fees and expenses, (b)
the  indemnifying party shall have failed promptly to assume the defense of such
action, claim or proceeding and to employ counsel reasonably satisfactory to the
indemnified  party  in  any  such  action, claim or proceeding, or (c) the named
parties  to  any  such  action,  claim  or  proceeding  (including any impleaded
parties)  include  both  such  indemnified party and the indemnifying party, and
such  indemnified party shall have been advised by counsel that there may be one
or more legal defenses available to it which are different from or additional to
those  available  to  the indemnifying party (in which case, if such indemnified
party  notifies  the  indemnifying  party  in  writing  that it elects to employ
separate  counsel  at  the  expense  of the indemnifying party, the indemnifying
party  shall  not  have the right to assume the defense of such action, claim or
proceeding  on  behalf  of such indemnified party, it being understood, however,
that  the  indemnifying party shall not, in connection with any one such action,
claim  or  proceeding  or separate but substantially similar or related actions,
claims  or  proceedings in the same jurisdiction arising out of the same general
allegations  or circumstances, be liable for the reasonable fees and expenses of
more  than  one  separate  firm  of  attorneys  (together with appropriate local
counsel)  at  any time for all such indemnified parties hereunder, unless in the
opinion  of  counsel for such indemnified party a conflict of interest may exist
between  such  indemnified  party and any other of such indemnified parties with
respect  to  such  action,  claim or proceeding, in which event the indemnifying
party shall be obligated to pay the fees and expenses of such additional counsel
or  counsels).  No  indemnifying  party will consent to entry of any judgment or
enter  into  any  settlement  which  does  not  include as an unconditional term
thereof  the  release of such indemnified party from all liability in respect to
such  claim or litigation without the written consent (which consent will not be
unreasonably  withheld)  of  the  indemnified party.  No indemnified party shall
consent  to  entry  of  any  judgment  or enter into any set-tlement without the
written  consent  (which  consent  will  not  be  unreasonably  withheld) of the
indemnifying  party  from  which  indemnity  or  contribution  is  sought.

     (d)     Contribution.  If  the indemnification provided for in this Section
             ------------
6 from the indemnifying party is unavailable to an in-demnified party in respect
of  any  Losses, then each applicable indemnifying party in lieu of indemnifying
such  indemnified party hereunder shall contribute to the amount paid or payable
by  such  indemnified party as a result of such Losses, in such proportion as is
appropriate  to  reflect  the  relative  fault  of  the  indemnifying  party and
indemnified  party in connection with the actions, statements or omissions which
resulted  in such Losses as well as any other relevant equitable considerations.
The relative fault of such indemnifying party and the indemnified party shall be
determined  by reference to, among other things, whether any action in question,
including  any  untrue  statement  of  a material fact or omission of a material
fact,  has  been  taken  or made by, or relates to information supplied by, such
indemnifying  party  or  indemnified  party,  and  the parties' relative intent,
knowledge,  access  to  information  and  opportunity to correct or prevent such
action,  statement  or  omission.  The  amount  paid  or payable by a party as a
result  of any Losses shall be deemed to include, subject to the limitations set
forth  in  Section 6(c), any legal or other fees or expenses reasonably incurred
by  such  party  in  connection  with  any action, suit, claim, investigation or
proceeding.

                                        8
<PAGE>
     The  parties  hereto  agree  that  it  would  not  be just and equitable if
contribution  pursuant  to  this  Section  6(d)  were  determined  by  pro  rata
allocation or by any other method of allocation which does not take into account
the equitable considerations referred to in the immediately preceding paragraph.
No  person guilty of fraudulent misrepresentation (within the meaning of Section
11(f)  of  the Securities Act) shall be entitled to contribution from any person
who  was  not  guilty  of  such  fraudulent  misrepresentation.

7.   Rule  144
     ---------

     The  Company  shall  file  the reports required to be filed by it under the
Securities Act and the Exchange Act and the rules and regulations adopted by the
Commission  thereunder,  and  will  take  such  further  action as any holder of
Registrable  Securities  may reasonably request, all to the extent required from
time  to  time  to  enable  such  holder  to sell Registrable Securities without
registration  under  the  Securities  Act within the limitation of the exemption
provided  by  Rule  144  or  Rule  144A.  Upon  the  request  of  any  holder of
Registrable  Securities,  the  Company  shall  deliver  to such holder a written
statement  as  to  whether  the  Company  has complied with such information and
requirements.  Notwithstanding the foregoing, nothing in this Section 7 shall be
deemed  to  require  the  Company  to  register  any of its securities under any
section  of  the  Exchange  Act.

8.   Underwritten  Registrations
     ---------------------------

     If  any of the Registrable Securities covered by any registration are to be
sold  in  an  underwritten offering, the investment banker or investment bankers
and  manager  or  managers that will administer the offering will be selected by
the  Company.  The Investor may not participate in any underwritten registration
hereunder  unless  the  Investor  (i) agrees to sell the  Investor's Registrable
Securities  on  the  basis provided in the underwriting arrangements approved by
the  Company,  and  (ii)  completes  and  executes all questionnaires, powers of
attorney,  indemnities,  underwriting  agreements  and  other documents required
under  the  terms  of  such  underwriting  arrangements.

9.   Miscellaneous
     -------------

     (a)     Amendments  and  Waivers.  The  provisions  of  this  Agreement,
             ------------------------
including  the  provisions  of  this  sentence,  may not be amended, modified or
supplemented,  and  waivers or consents to departures from the provisions hereof
may not be given unless the Company obtains the written consent of holders of at
least a majority of the then outstanding Registrable Securities affected by such
amendment,  modification or supplement.  Notwithstanding the foregoing, a waiver
or  consent  to depart from the provisions hereof with respect to a matter which
relates  exclusively  to  the  rights of holders of Registrable Securities whose
securi-ties  are  being sold pursuant to a Registration Statement and which does
not  directly  or  indirectly  affect  the  rights  of  holders  of  Registrable
Securities  whose  securities  are  not being sold pursuant to such Registration
Statement  may  be  given by holders of a majority of the Registrable Securities
being  sold  by  such  holders.

                                        9
<PAGE>
     (b)     Notices.  All  notices  and  other  communications  provided for or
             -------
permitted  hereunder  shall  be  made  in  writing  by hand-delivery, registered
first-class  mail,  next day air courier, telex, or telecopy: (i) if to a holder
of  Registrable  Securities, at the most current address given by such holder to
the  Company  in  accordance  with  the  provisions  of this Section 9(b), which
address  initially  is,  with  respect to the Investor, the address set forth in
Section B of the Purchase Agreement; and (ii) if to the Company, at 900 Veterans
Boulevard,  Suite  240, Redwood City California 94063, attention: Secretary, and
thereafter  at  such  other address, notice of which is given in accordance with
the  provisions  of  this  Section  8(b).

     All  such  notices  and  communications  shall  be deemed to have been duly
given:  when delivered by hand, if personally delivered; two business days after
being  deposited in the mail, postage prepaid, if mailed; one business day after
being  sent  by  next  day air courier; when answered back, if telexed; and when
receipt  acknowledged,  if  telecopied.

     (c)     Transfer of Registration Rights.  The rights granted to the holders
             -------------------------------
pursuant  to  this Agreement to cause the Company to register securities may not
be  assigned  or  otherwise transferred in any way other than to an Affiliate of
the  holder to whom the holder has transferred all or any part of the Warrant or
the  Amended  Note.

     (d)     Counterparts.  This  Agreement  may  be  executed  in any number of
             ------------
counterparts  by  the  parties  hereto,  each of which when so executed shall be
deemed  to  be  an original and all of which taken together shall constitute one
and  the  same  agreement.

     (e)     Headings.  The  headings  in  this Agreement are for convenience of
             --------
reference  only  and  shall  not  limit  or otherwise affect the meaning hereof.

     (f)     Governing  Law.  This  Agreement shall be governed by and construed
             ---------------
in  accordance  with  the  laws  of  the  State  of  New  York without regard to
principles  of  conflict  of  laws.

     (g)     Severability.  If  any  term, provision, covenant or restriction of
             ------------
this  Agreement is held by a court of competent jurisdiction to be invalid, void
or  unenforceable,  the  remainder  of  the  terms,  provisions,  covenants  and
restrictions set forth herein shall remain in full force and effect and shall in
no  way  be  affected, impaired or invalidated, and the parties hereto shall use
their  best  efforts to find and employ an alternative means to achieve the same
or  substantially  the same result as that contemplated by such term, provision,
covenant  or  restriction.  It  is  hereby  stipulated  and  declared  to be the
intention  of  the  parties  that  they would have executed the remaining terms,
provisions,  covenants  and restrictions without including any of such which may
be  hereafter  declared  invalid,  void  or  unenforceable.

     (h)     Entire  Agreement.  This Agreement is intended by the parties to be
             -----------------
a  final expression of their agreement and a complete and exclusive statement of
the  agreement and understanding of the parties hereto in respect of the subject
matter  contained  herein.  There  are no restrictions, promises, warranties nor

                                       10
<PAGE>
undertakings,  other  than those set forth or referred to herein with respect to
the  registration  rights  granted by the Company with respect to the securities
sold  pursuant  to  the Purchase Agreement.  This Agreement supersedes all prior
agreements  and  understandings between the parties with respect to such subject
matter.

     (i)     Attorneys' Fees.  If any action or proceeding is brought to enforce
             ----------------
any  provision  of  this  Agreement,  or  where  any provision hereof is validly
asserted  as  a  defense,  the  successful  party  shall  be entitled to recover
reasonable  attorneys'  fees in addition to its costs and expenses and any other
available  remedy.

                          COMMON STOCK PURCHASE WARRANT
                          Void after December 13, 2003

                                          Warrant  to  Purchase  300,000  Shares
                                            of  Common  Stock,  $.01  par  value
                                                   of  Penn  Octane  Corporation

                        PENN  OCTANE  CORPORATION  (POCC)

This  is  to  Certify  That,  FOR  VALUE  RECEIVED,

                              KFP  Grand  LTD.

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  December  13, 2003 (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),  300,000  shares  of  Common  Stock,  $.01  par value, of the Company (the
"Common  Stock")  at an exercise price of $1.75 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."

<PAGE>
     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,
free  of  preemptive  rights  and  any  other  rights  of  others.

     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/AMEX Stock Market, or, if the Common
Stock is not then listed or admitted to trading on the NASDAQ/AMEX 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

                                        2
<PAGE>
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 11 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:

          1.     pays  a dividend or makes a distribution on its Common Stock in
shares  of  its  Common  Stock;

          2.     subdivides  its  outstanding  shares  of  Common  Stock  into a
greater  number  of  shares;

          3.     combines  its outstanding shares of Common Stock into a smaller
number  of  shares;

          4.     makes  a  distribution  on  its  Common  Stock in shares of its
capital  stock  other  than  Common  Stock;  or

          5.     issues  by  reclassification  of its Common Stock any shares of
its  capital  stock;

                                        3
<PAGE>
then  the  Exercise  Price  in  effect  immediately prior to such action and the
number  of  shares  and type of capital stock issuable upon the exercise of this
Warrant  shall  be  adjusted  so  that  the Holder may receive, upon exercise or
exchange  of  this  Warrant  and  payment of the same aggregate consideration as
provided  herein and any proportionate part thereof upon any partial exercise of
this  Warrant,  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 the applicable record
date  or  effective  date  of  such  action.

     The adjustment shall become effective immediately after the record date for
the  determination  of  stockholders  entitled  to  receive  the  dividend  or
distribution  in  the case of a dividend or distribution and as of the effective
date  of  any  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  its  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 security 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.     When  No  Adjustment  Required.  No  adjustment  need  be made for a
            ------------------------------
change  in  the  par  value  of  the  Common  Stock.

                                        4
<PAGE>
     D.     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  and nature of the adjustment 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 and/or description of the other
capital  stock  and  number  of  shares  of  the other capital stock purchasable
hereunder  after  giving  effect  to  such  adjustment, and shall promptly cause
copies  of  such  certificates  to  be  mailed  to  the  Holder.

     E.     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.

     F.     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.

     G.     Common Stock Defined.  Whenever reference is made in Section 6(a) to
            --------------------
the  issue  of shares of Common Stock, the term "Common Stock" shall include any
equity securities of any class of the Company hereinafter authorized which shall
not  be  limited  to  a  fixed  sum or percentage in respect of the right of the
holders  thereof to participate in dividends or distributions of assets upon the
voluntary  or involuntary liquidation, dissolution or winding up of the Company.
Subject  to  the  provisions  of Section 7 hereof, however, 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.     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 which shall be (x) the record date for
determining  the  stockholders of the Company entitled to receive 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

                                        5
<PAGE>
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.

     8.     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 upon the exercise of this
Warrant.  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.

     9.     Repurchase  Right.  Notwithstanding  any  other  provisions  of this
            -----------------
Warrant, the Company may, in the event that, after the date six months after the
date hereof, the closing bid price, as reported on the NASDAQ/AMEX or such other
exchange  on  which  the  Company's  Common  Stock  may  then  be quoted, of the
Company's  Common Stock is greater than $3.00 for five consecutive trading days,
upon  not  less  than ten (10) 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  five  (5)  day  period,  the  Holder  may exercise such Warrant in
accordance with the terms hereof.  The closing on such repurchase shall occur on
the  date  and at the time set forth in such notice at the office of the Company
in  Redwood City, California or at such other place as shall be specified by the
Company.  At  the  Closing,  the  Company  shall deliver to the Holder an amount
equal  to  the purchase price in immediately available funds and the Holder will
deliver  this  Warrant  to  the  Company  for  cancellation.  To  the extent any
repurchase  hereunder  is  of  less  than  all of the rights represented by this
Warrant,  the  Company  will  deliver  to  the Holder a new Warrant covering the
rights  not  so  purchased.

     10.     Determination  by  Board  of  Directors.  All determinations by the
             ---------------------------------------
Board  of  Directors of the Company under the provisions of this Warrant will be
made  in  good  faith  with  due  regard  to  the  interest of the Holder and in
accordance  with  sound  financial  practices.

     11.     Notice.  All  notices  to  the  Holder shall be in writing, and all
             ------
notices  and  certificates  given  to  the  Holder  shall  be sent registered or
certified  mail,  return  receipt  requested,  to  such  Holder  at  his address
appearing  on  the  records  of  the  Company.

     12.     Replacement of Lost, Stolen, Destroyed or Mutilated Warrants.  Upon
             ------------------------------------------------------------
receipt  of  evidence reasonably satisfactory to the Company of the loss, theft,
destruction  or  mutilation  of  this Warrant and, in the case of any such loss,
theft  or  destruction,  upon  delivery of any indemnity bond in such reasonable
amount as the Company may determine and in the case of any such mutilation, upon

                                        6
<PAGE>
the surrender of such Warrant for cancellation, the Company at its expense, will
execute  and  deliver,  in  lieu  of  such  lost, stolen, destroyed or mutilated
Warrant,  a  new  Warrant  of  like  tenor.

     13.     Number  and  Gender.  Whenever  the singular number is used herein,
             -------------------
the  same  shall  include  the plural where appropriate, and words of any gender
shall  include  each  other  gender  where  appropriate.

     14.     Applicable  Law.  This  Warrant shall be governed by, and construed
             ---------------
in  accordance  with,  the  laws of the State of New York, without regard to its
conflict  of  law  principles.

          (b) The  Royalty  Payments  now due or  payable  in the  future by WAC
     and/or POC after giving  effect and taking into  consideration  any and all
     offsets to such  Royalty  Payments  made  through  the date of this  Second
