                      ____________________________________

                      Up to 440,861 shares of Common Stock
                      ____________________________________


     This Prospectus relates to up to 440,861 shares of common stock, par  value
$.16-2/3  per  share ("Tesoro Common Stock"), of Tesoro Petroleum Corporation, a
Delaware corporation ("Tesoro" or the "Company") that may be issued upon (a) the
exercise of outstanding transferable  stock  warrants  (the "Warrants"), (b) the
exercise of outstanding stock options (the "Stock Options")  and  (c)  upon  the
conversion of outstanding convertible debentures (the "Convertible Debentures").
The Warrants, Stock Options and Convertible Debentures were originally issued by
Coastwide Energy Services, Inc. ("Coastwide") prior to its merger (the "Merger")
into a wholly-owned subsidiary of Tesoro.

     On  February  20, 1996, Coastwide was merged with and into CNRG Acquisition
Corp.  ("CNRG"), a  wholly-owned  subsidiary  of  Tesoro.   As  a result of such
Merger, Coastwide effectively became a wholly-owned subsidiary of Tesoro and (i)
each outstanding share of Coastwide common stock,  $.01  par  value  ("Coastwide
Common  Stock"),  was  converted into the right to receive $2.55 in cash and .41
share of Tesoro Common Stock (and cash in lieu of any fractional share) together
with any associated Preferred Stock Purchase Rights (the "Merger Consideration")
and (ii) each outstanding  Warrant,  Stock  Option and Convertible Debenture was
adjusted so that, upon exercise or  conversion,  the  holder  will  receive,  in
effect,  the  Merger  Consideration for the number of shares of Coastwide Common
Stock that would  have  been  issuable  upon  exercise or conversion immediately
prior to the Merger.

     No person has been authorized to  give  any  information  or  to  make  any
representation  other  than those contained or incorporated by reference in this
Prospectus in connection with the  offering  of securities described herein and,
if given or made, such information or representation should not be  relied  upon
as  having  been authorized by Tesoro or any other person.  This Prospectus does
not constitute an offer to sell,  or  the  solicitation of an offer to purchase,
any securities in any jurisdiction in which, or to any person  to  whom,  it  is
unlawful  to  make  such  offer  or  solicitation.  Neither the delivery of this
Prospectus nor any distribution of  the securities described herein shall, under
any circumstances, create any implication that there has been no change  in  the
affairs  of  Tesoro  since  the date hereof or that the information set forth or
incorporated by reference herein is  correct  as  of  any time subsequent to its
date.

                                  THE COMPANY

     Tesoro is a natural resource company  engaged  in  petroleum  refining  and
marketing,  natural  gas  exploration and production, and wholesale marketing of
fuel and lubricants.  Tesoro was  incorporated  in Delaware in 1968 (a successor
by merger to a California corporation incorporated in 1939).

     Tesoro's Refining and Marketing segment's operations in Alaska include:   a
refinery  that  produces  gasoline, jet fuel, diesel fuel, heavy distillates and
residual products; a retail  marketing  system  that  sells gasoline through the
Company's  chain  of  licensed  7-Eleven  stores;  a  distribution  system  that
wholesales gasoline to both branded and unbranded dealers  and  jobbers;  and  a
wholesale  marketing  operation  that  supplies  a  substantial  portion  of the
commercial jet fuel and diesel fuel sold in Alaska.  In addition, this segment's
marketing  operations  provide  supply,  storage  and  distribution  services in
California and the Pacific Northwest and has recently commenced selling gasoline
on a wholesale basis in the Russian  Far  East  and  to  Tesoro-branded  service
stations in the Pacific Northwest.

     Tesoro's Exploration and Production segment is primarily focused in the Bob
West  Field  in South Texas, which was discovered by Tesoro in 1990.  During the
third quarter of  1995,  Tesoro  sold  certain  interests  in  its producing and
non-producing properties in  the  Bob  West  Field  for  an  adjusted  price  of
approximately  $68  million, resulting in an after-tax gain of approximately $33
million.  The  interests  sold  represented  approximately  77  Bcf,  or 40%, of
Tesoro's total proved domestic natural gas reserves at the time of the sale.   A
portion of the consideration received by Tesoro for the sale of these interests,
which  is  subject to post-closing adjustments, was used to redeem $34.6 million
principal amount of  Tesoro's  outstanding  12  %  Subordinated Debentures.  The
remainder of the consideration received was  used  to  reduce  borrowings  under
Tesoro's  Revolving Credit Facility and improve Tesoro's liquidity.  Tesoro does
not expect any final post-closing  adjustments  to be material.  Tesoro also has
operations in southern Bolivia that include significant  natural  gas  reserves,
the majority of which are shut-in awaiting access to gas-consuming markets.

     Tesoro's  former Oil Field Supply and Distribution segment sold lubricants,
fuels  and  specialty  petroleum   products,   primarily  to  offshore  drilling
contractors.   In  the  third  quarter  of  1995,  Tesoro  consolidated  certain
operations in this segment by exiting the land-based portion  of  its  petroleum
product  distribution  business  in  Texas, and continued to operate shore-based
terminals on  the  Texas  and  Louisiana  Gulf  Coast.   On  February  20, 1996,
Coastwide's  operations  were  combined  with  Tesoro's  Oil  Field  Supply  and
Distribution  segment  forming  a  Marine  Services  segment.   As  a   combined
operation,  the  Marine  Services  segment  consists  of 18 terminals, primarily
marine based,  providing  a  broad  range  of  products  and  logistical support
services to the offshore industries operating in the U.S. Gulf of Mexico.

     During 1994, Tesoro consummated a recapitalization plan and equity offering
whereby a major portion of its outstanding debt was restructured and all of  its
preferred  stock  and dividend arrearages were eliminated and which, among other
matters,  deferred  $44   million   of   debt  service  requirements,  increased
stockholders' equity by approximately $82 million and eliminated $9.2 million of
annual preferred  dividend  requirements.   In  addition,  the  recapitalization
enabled  Tesoro to enter into a $125 million Corporate Revolving Credit Facility
and to obtain  $15  million  financing  for  a  major  addition to the Company's
refinery.

     The Company's principal executive offices are located at 8700 Tesoro Drive,
San Antonio, Texas 78217, and its telephone number is (210) 828-8484.

     Information concerning the business  of  Tesoro  and  the  results  of  its
operations  for  the  three  most  recent  fiscal years is contained in Tesoro's
Annual Report on Form 10-K for the year ended December 31, 1994, with updates in
quarterly reports on Form 10-Q for the quarterly periods ended March 31, June 30
and September 30, 1995, as well as current reports on Form 8-K dated October 11,
1995, December 15, 1995 and January  31,  1996, all of which are incorporated by
reference in this Prospectus.


                                USE OF PROCEEDS

     There are not expected to be any material proceeds to the  Company  because
the exercise price of the Warrants and of most of the Stock Options is less than
the cash portion of the Merger Consideration.


                              PLAN OF DISTRIBUTION

     In  connection  with the Merger, each outstanding Warrant, Stock Option and
Convertible Debenture  of  Coastwide  was  adjusted  so  that,  upon exercise or
conversion, the holder will receive the Merger Consideration for the  number  of
shares  of Coastwide Common

                                      -3-

Stock that would have been issuable  upon  exercise  or  conversion  immediately
prior  to  the  Merger.   The  following  is  a  description  of  the  Warrants,
Convertible Debentures and Stock Options.

     Warrants.   As  of the effective time of the Merger (the "Effective Time"),
Coastwide had outstanding Warrants  to  purchase approximately 355,946 shares of
Coastwide Common Stock for $1.54 per share (the "Warrant Price"), subject to the
terms and conditions of a Warrant Agreement, effective as of October  29,  1993,
between Coastwide and Chemical Shareholder Services Group, Inc. as Warrant Agent
(the  "Warrant  Agreement").  The Warrants expire December 22, 1996.  Tesoro has
entered into an  amendment  to  the  Warrant  Agreement  with the Warrant Agent,
giving each holder of Warrants the right (prior to the expiration  date  of  the
Warrants  and  upon  payment  of the Warrant Price), to receive upon exercise of
each Warrant the  Merger  Consideration  that  could  have  been received at the
Effective Time if the Warrant had been exercised immediately prior thereto.  For
example, a holder of 10,000 Warrants would, after the Effective Time, and  prior
to December 22, 1996, be entitled to receive, upon payment of the exercise price
of  $15,400 ($1.54 times 10,000), $25,500 in cash ($2.55 times 10,000) and 4,100
shares of Tesoro Common Stock (.41  share  of Tesoro Common Stock times 10,000).
The Company has reserved 145,938 shares of Tesoro Common Stock for issuance upon
the exercise of the Warrants.

     Convertible  Debentures.   As  of  the  Effective   Time,   Coastwide   had
outstanding  $2,545,000  of Convertible Debentures due July 1, 2004, convertible
into Coastwide Common Stock  at  $4.25  per  share  (598,824 shares of Coastwide
Common Stock).  Pursuant to a  Debenture  Assumption  and  Conversion  Agreement
entered  into  among  Tesoro,  CNRG  and Coastwide, CNRG assumed the Convertible
Debentures  and  from  and  after  the  Effective  Time.   The  holders  of  the
Convertible Debentures have  the  right  to  convert such Convertible Debentures
into the Merger Consideration that would have been received by a holder had such
Convertible Debentures been converted immediately prior to  the  Merger.   Thus,
for example, a holder of $42,500 principal amount of the Convertible Debentures,
which prior to the Effective Time would have been convertible into 10,000 shares
of  Coastwide  Common  Stock,  would be entitled after the Merger to convert the
Convertible Debentures into 4,100 shares  of  Tesoro Common Stock and $25,500 in
cash, which is the number of shares of Tesoro Common Stock  and  the  amount  of
cash,  respectively,  that  a  holder of 10,000 shares of Coastwide Common Stock
would have received upon conversion  of  his  shares in the Merger.  The Company
has reserved 245,518 shares of Tesoro Common Stock for issuance upon  conversion
of the Convertible Debentures.

     Stock  Options.   As of the Effective Time, Coastwide had 120,500 shares of
Coastwide Common Stock reserved  for  issuance  pursuant  to options granted and
currently outstanding under Coastwide's stock option plans.  Each of the  shares
reserved  for  issuance  pursuant  to  the  Stock  Options  is  fully vested and
exercisable.  As of the Effective  Time,  each  holder of a Stock Option entered
into a Cancellation/Substitution Agreement pursuant to  which  each  outstanding
and  unexercised  Stock  Option  immediately  prior to the Effective Time became
exercisable for the Merger Consideration rather than for Coastwide Common Stock.
More specifically, as of the Effective Time, each Stock Option was automatically
converted into an option to purchase Tesoro  Common Stock in an amount and at an
exercise price determined as provided  below  (and  otherwise  having  the  same
duration and other terms as the original option):

          (1)  The  number of shares of Tesoro Common Stock to be subject to the
new option is equal to the product  of  the number of shares of Coastwide Common
Stock subject to the original option  and  .41,  provided  that  any  fractional
shares  of Tesoro Common Stock resulting from such multiplication are rounded to
the nearest whole share; and

          (2)  The exercise price per share of Tesoro Common Stock to be subject
to the new option is equal to (a) the exercise price of the number of shares  of
Coastwide  Common  Stock  under  the  original  option  divided by .41 minus (b)
$6.2195 (rounded to the nearest cent), provided that if such amount is less than
$0, the holder of such option shall, upon exercise, receive, in cash, the amount
by which such amount is less than $0.

The Company has reserved 49,405 shares  of Tesoro Common Stock for issuance upon
exercise of the Stock Options.


                                 LEGAL MATTERS

     The validity of the  shares  of  Tesoro  Common  Stock  issuable  upon  the
exercise or conversion of the Warrants, Stock Options and Convertible Debentures
has been passed upon by Fulbright & Jaworski L.L.P.

Item 17.  Undertakings.

     A.   Undertaking Pursuant to Rule 415.

     The undersigned registrant hereby undertakes:

          (1)  to  file,  during  any  period in which offers or sales are being
made, a post-effective amendment to this registration statement:

          (i) to include  any  prospectus  required  by  Section 10(a)(3) of the
Securities Act of 1933;

          (ii) to reflect in the prospectus any facts or  events  arising  after
     the  effective  date  of  the  registration  statement  (or the most recent
     post-effective amendment thereof) which,  individually or in the aggregate,
     represent a  fundamental  change  in  the  information  set  forth  in  the
     registration statement;

          (iii) to include any material information with respect to the plan  of
     distribution  not previously disclosed in the registration statement or any
     material change to such information in the registration statement;

          provided, however, that paragraphs (1)(i) and (1)(ii) do not apply, if
the registration statement is  on  Form  S-3  or  Form  S-8, and the information
required to be included in a post-effective amendment  by  those  paragraphs  is
contained  in periodic reports filed by the registrant pursuant to Section 13 or
Section 15(d) of the Securities  Exchange  Act  of 1934 that are incorporated by
reference in the registration statement.

          (2) that, for the purpose  of  determining  any  liability  under  the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering  of such securities at that time shall be deemed to be the initial bona
fide offering thereof; and

          (3) to remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination of
the offering.

     B.   Undertaking Regarding Documents Subsequently Filed Under the  Exchange
Act.

     The  undersigned  registrant  hereby   undertakes  that,  for  purposes  of
determining any liability under the Securities Act of 1933, each filing  of  the
registrant's  annual  report  pursuant  to Section 13(a) or Section 15(d) of the
Securities Exchange Act  of  1934  (and,  where  applicable,  each  filing of an
employee  benefit  plan's  annual  report  pursuant  to  Section  15(d)  of  the
Securities Exchange Act of 1934)  that  is  incorporated  by  reference  in  the
registration  statement  shall  be  deemed  to  be  a new registration statement
relating to the securities offered therein,  and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

     C.   Undertaking Regarding Request for Acceleration of Effective Date.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons  of  the
registrant  pursuant  to  the foregoing provisions, or otherwise, the registrant
has been advised that in the  opinion  of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
of 1933 and is, therefore,  unenforceable.   In  the  event  that  a  claim  for
indemnification  against  such  liabilities  (other  than  the  payment  for the
registrant of expenses incurred or  paid  by  a director, officer or controlling
person of the registrant in the  successful  defense  of  any  action,  suit  or
proceeding)  is  asserted  by  such  director,  officer or controlling person in
connection with the securities being  registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to  a  court  of  appropriate  jurisdiction  the  question  whether  such
indemnification  by  it  is against public policy as expressed in the Securities
Act of 1933 and will be governed by the final adjudication of such issue.

                                      II-2

                                   SIGNATURES

     Pursuant to the requirements of the  Securities Act of 1933, the Registrant
certifies that it has reasonable grounds to believe that it  meets  all  of  the
requirements  for  filing  on  Form  S-3 and has duly caused this Post-Effective
Amendment No. 1 on Form S-3 to  its Form S-4 Registration Statement to be signed
on its behalf by the undersigned, thereunto duly authorized, in the city of  San
Antonio, State of Texas, on the 26th day of February, 1996.

                        COASTWIDE ENERGY SERVICES, INC.

                                      and

                   CHEMICAL SHAREHOLDER SERVICES GROUP, INC.

                                as Warrant Agent

                          Class B Warrants to Purchase
                  Approximately 400,000 Shares of Common Stock
                                 Par Value $.01


                               WARRANT AGREEMENT

                        Effective as of October 29, 1993


         THIS WARRANT AGREEMENT, dated as of  September 30, 1993, is made by and
between COASTWIDE ENERGY SERVICES, INC., a Delaware corporation (the "Company"),
and Chemical Shareholder Services Group, Inc., a national  banking  association,
as  warrant  agent (the "Warrant Agent").  The Company proposes to issue Class B
warrants, as  hereinafter  described  (the  "Warrants"),  to  purchase  up to an
aggregate of approximately 400,000 shares of its common stock,  par  value  $.Ol
per  share (the "Common Stock") (the shares of Common Stock issuable in exercise
of the Warrants being referred to herein as the "Warrant Shares").

         The Company has requested the  Warrant  Agent  to  act on behalf of the
Company, and the Warrant Agent is willing so to  act,  in  connection  with  the
issuance,  transfer, exchange and replacement of the certificates evidencing the
Warrants (the "Warrant Certificates"), and the exercise of the Warrants.

         In consideration of the foregoing  and  for the purpose of defining the
terms and provisions of the Warrants and the respective rights  and  obligations
thereunder  and  hereunder  of  the  Company,  the Warrant Agent, the registered
owners of  the  Warrants  (the  "Holders"),  and  for  other  good  and valuable
consideration, the receipt and sufficiency of which is hereby  acknowledged  and
confirmed, the Company and the Warrant Agent agree as follows:

         Section  1  Appointment  of Warrant Agent.  The Company hereby appoints
the Warrant Agent  to  act  as  agent  for  the  Company  in accordance with the
instructions set forth in this Agreement, and the Warrant Agent  hereby  accepts
such appointment.

         Section  2  Form  of  Warrant  Certificates.   The  text of the Warrant
Certificates (and  the  form  of  election  to  purchase  Warrant  Shares and of
assignment to be printed on the reverse thereof) shall be substantially  as  set
forth  in Exhibit A hereto, and may have such letters, numbers or other marks of
identification  or  designation  and  such  legends,  summaries  or endorsements
printed, lithographed or engraved thereon as the Company  may  deem  appropriate
and  as are not inconsistent with the provisions of this Agreement, or as may be
required to comply with any  law  or  with  any rule or regulation made pursuant
thereto or with any rule or regulation  of  any  stock  exchange  on  which  the
Warrants  may  from  time  to  time  be listed, or to conform to usage.  Warrant
Certificates shall be dated as of  the  date  of issuance thereof by the Warrant
Agent, rather upon initial issuance or upon transfer or exchange, and  on  their
face  shall entitle the holders thereof to purchase one share (for each Warrant)
of Common Stock, but no purchase  shall  be permitted except with respect to one
share or multiples of one share and the number of such shares and  the  purchase
price per share shall be subject to adjustment as provided herein.

    Pending  the preparation of definitive Warrant Certificates, the Company may
execute and  the  Warrant  Agent  shall  countersign  in  lieu thereof temporary
Warrant Certificates, substantially  in  the  form  of  the  definitive  Warrant
Certificates  but  with  such  omissions,  insertions  and  variations as may be
determined  to  be  appropriate  by  the  Board  of  Directors  of  the Company.
Temporary Warrant Certificates may be issued with such provisions  with  respect
to exchanges of temporary Warrant Certificates as may be determined by the Board
of  Directors  of  the  Company and may contain such references to provisions of
this  Warrant  Agreement  as  may   be  appropriate.   Every  temporary  Warrant
Certificate shall be executed by the Company and be countersigned by the Warrant
Agent upon the same conditions and in substantially the same manner and with the
like effect as the definitive Warrant Certificates.  In the case of the issuance
of temporary  Warrant  Certificates,  the  Company  shall  prepare  and  execute
definitive  Warrant Certificates without unnecessary delay and thereupon any and
all temporary Warrant Certificates  may  be  surrendered in exchange therefor at
the  principal  office  of  the  Warrant  Agent  and  the  Warrant  Agent  shall
countersign and deliver in exchange  for  such  temporary  Warrant  Certificates
definitive Warrant Certificates for an equal aggregate number of Warrants as may
be requested by the holders thereof.  Until so exchanged, each temporary Warrant
Certificate  shall  be  entitled  to  the  same benefits as a definitive Warrant
Certificate.

    Section 3  Counter  Signature  and  Registration.   The Warrant Certificates
shall be executed on behalf of the Company by its Chairman  of  the  Board,  its
President  or  a  Vice  President,  by  manual  or facsimile signature, and have
affixed thereto a facsimile of the Company's seal which shall be attested by the
Secretary or an  Assistant  Secretary  of  the  Company  by  manual or facsimile
signature.  The Warrant Certificates shall  be  manually  countersigned  by  the
Warrant  Agent  and  shall not be valid for any purpose unless so countersigned.
In case any officer of  the  Company  who  shall  have signed any of the Warrant
Certificates  shall  cease  to  be  such   officer   of   the   Company   before
countersignature  by the Warrant Agent and issuance and delivery by the Company,
such Warrant Certificates,  nevertheless,  may  be  countersigned by the Warrant
Agent and issued and delivered with the same force  and  effect  as  though  the
person who signed such Warrant Certificates had not ceased to be such officer of
the Company.

    The  Warrant  Agent  will keep or cause to be kept, at its principal office,
books for registration  and  transfer  of  the  Warrants  issued hereunder.  The
Warrants shall be issued in registered form only.  The registration books  shall
show  the  names and addresses of the respective Holders, the number of Warrants
evidenced on its face by each of  the Warrant Certificates, and the date of each
of the Warrant Certificates.   The  Company  and  the  Warrant  Agent  shall  be
entitled to treat a Holder as the owner in fact for all purposes of each Warrant
registered  in  such  Holder'  s  name  and  shall not be bound to recognize any
equitable or other claim to or interest in such Warrant on the part of any other
person, and shall not be  liable  for  any  registration of transfer of Warrants
that are registered or to be registered in  the  name  of  a  fiduciary  or  the
nominee of a fiduciary unless made with the actual knowledge that a fiduciary or
nominee  is  committing  a  breach  of  trust in requesting such registration of
transfer, or with such knowledge  of  such  facts that its participation therein
amounts to bad faith.

    Section 4 Transfer.  The Warrants shall be transferable only on the books of
the Company maintained at the principal  office  of the Warrant Agent in Dallas,
Texas, upon delivery thereof  duly  endorsed  by  the  Holder  or  by  his  duly
authorized  attorney or representative, which endorsement shall be guaranteed by
a commercial bank or a trust company located in the United States or by a member
firm of a registered national  securities  exchange  or a member of the National
Association of Securities Dealers, Inc., or accompanied by  proper  evidence  of
succession, assignment or authority to transfer.  In all cases of transfer by an
attorney,  the  original  power  of attorney, duly approved, or an official copy
thereof, duly certified, shall be  deposited  and remain with the Warrant Agent.
In case of transfer by  executors,  administrators,  guardians  or  other  legal
representatives,  duly  authenticated  evidence  of  their  authority  shall  be
produced,  and may be required to be deposited and remain with the Warrant Agent
in its discretion.  Upon any  registration  of transfer, the Warrant Agent shall
countersign and deliver a new Warrant Certificate or Certificates to the persons
entitled thereto.

         Section  5  Exchange of Warrant Certificates.  Each Warrant Certificate
may be exchanged at the option of  the Holder thereof for another certificate or
certificates entitling the Holder thereof to purchase a like aggregate number of
Warrant Shares as the certificate or certificates surrendered then entitle  such
Holder  to  purchase.   Any Holder desiring to exchange a Warrant certificate or
certificates shall make such request in  writing delivered to the Warrant Agent,
and shall surrender, properly endorsed, which endorsement shall be guaranteed as
provided in Section 4 hereof if the certificate or certificates are to be issued
other than in the name of the Holder, the certificate or certificates to  be  so
exchanged  at  the office of the Warrant Agent in Dallas, Texas.  Thereupon, the
Warrant Agent shall countersign and deliver to the person entitled thereto a new
Warrant Certificate or Certificates as the case may be, as so requested.

         Section 6 Term of Warrants: Exercise of Warrants.

         6.1 Term of Warrants.   Subject  to  the  provisions of this Agreement,
each Holder shall have the right at any time prior to 5:00 P.M.,  Dallas,  Texas
time, on December 22, 1996 (the "Expiration Date"), to purchase from the Company
the number of fully paid and nonassessable Warrant Shares that the Holder may at
the  time  be  entitled  to  purchase  on  exercise of such Warrants.  After the
Expiration Date, any previously unexercised  Warrants  shall be void and have no
value.

         6.2 Exercise of Warrants.  A Warrant may be exercised upon surrender to
the Command at the  office  of  the  Warrant  Agent  in  Dallas,  Texas  of  the
certificate  or  certificates evidencing no fewer than the number of Warrants to
be exercised, together with the  duly  completed  and signed form of election to
purchase on the reverse thereof, and upon payment to the Warrant Agent  for  the
account  of  the  Company  of the Warrant Price (as defined in and determined in
accor- dance with the provisions of Section  10 and 11 hereof) for the number of
Warrant Shares in respect of which such Warrants are then exercised.  Payment of
the aggregate Warrant Price shall be made in lawful, money of the United  States
of  America,  in cash, by cashier's check, certified check or bank draft payable
to the order of the Company.

         Subject to  Section  7  hereof,  upon  such  surrender  of Warrants and
payment of the Warrant Price, the Company shall issue and cause to be  delivered
with  all  reasonable dispatch to or upon the written order of the Holder and in
such name or names as  the  Holder  may designate, a certificate or certificates
for the number of full Warrant Shares so purchased upon  the  exercise  of  such
Warrants,  together  with  cash, as provided in Section 12 hereof, in respect of
any fractional Warrant  Shares  otherwise  issuable  upon  such surrender.  Such
certificate or certificates shall be deemed to have been issued and  any  person
so  designated  to  be  named therein shall be deemed to have become a holder of
record of such Warrant Shares as of  the  date of the surrender of such Warrants
and payment of the Warrant Price; provided, however, that if,  at  the  date  of
surrender of such Warrants and payment of such Warrant Price, the transfer books
for  the Warrant Shares or other class of stock purchasable upon the exercise of
such Warrants shall  be  closed,  the  certificates  for  the  Warrant Shares in
respect of which such Warrants are then exercised shall be issuable  as  of  the
date  on  which  such  books  shall  next be opened (whether before or after the
Expiration Date) and until  such  date  the  Company  shall  be under no duty to
deliver any certificate  for  such  Warrant  Shares.   The  rights  of  purchase
represented by the Warrants shall be exercisable, at the election of the Holders
thereof,  either  in  full  or  from  time to time in part and, if a certificate
evidencing Warrants is exercised  in  respect  of  less  than all of the Warrant
Shares purchasable on such exercise at any time prior to the Expiration Date  or
earlier  redemption of such Warrants, a new certificate evidencing the remaining
Warrant or Warrants will be issued,  and the Warrant Agent is hereby irrevocably
authorized to countersign and to deliver the required new  Warrant  Certificates
pursuant  to  the  provisions  of  this  Section and of Section 3 hereof and the
Company, whenever required by the  Warrant  Agent, will supply the Warrant Agent
with Warrant Certificates duly executed  on  behalf  of  the  Company  for  such
purpose.

         Section 7 Payment of Taxes.  The Company will pay any documentary stamp
taxes  attributable  to  the  issuance  of  Warrant  Shares upon the exercise of
Warrants; provided, however, that the Company  shall  not be required to pay any
tax or taxes that may be payable in respect of  any  transfer  involved  in  the
issue  or  delivery of any Warrant Shares, Warrants or Warrant Certificates in a
name other than that of the  registered  Holder  of Warrants in respect of which
such Warrant Shares are issued, and the Company shall not be required  to  issue
or  deliver  such  certificates unless or until the person or persons requesting
the issuance thereof shall have paid  to  the  Company the amount of such tax or
shall have established to the satisfaction of the Company that such tax has been
paid.

         Section 8 Mutilated or Missing Warrant Certificates.   If  any  of  the
Warrant  Certificates shall be mutilated, lost, stolen or destroyed, the Company
may in its discretion issue, and the Warrant Agent shall countersign and deliver
in exchange and substitution for and  upon cancellation of the mutilated Warrant
Certificate, or in lieu of and substitution for the  Warrant  Certificate  lost,
stolen or destroyed, a new Warrant Certificate of like tenor and representing an
equivalent right or interest:  but only upon receipt of evidence satisfactory to
the  Company  and  the  Warrant Agent of such loss, theft or destruction of such
Warrant Certificate and a  bond  or  other  indemnity  satisfactory to them.  An
applicant for such a substitute Warrant Certificate shall also comply with  such
other  reasonable  requirements  and  pay  such  other reasonable charges as the
Company or the Warrant Agent may prescribe.

         Section 9 Reservation of Warrant Shares: Purchase of Warrants.

         9.1 Reservation  of  Warrant  Shares.   Prior  to  the  issuance of any
Warrants the Company shall reserve, and the  Company  shall  thereafter  at  all
times  keep  reserved, free from preemptive rights, out of its authorized Common
Stock, a number of shares of Common Stock sufficient to provide for the exercise
of the rights of purchase represented by the outstanding Warrants.  The transfer
agent and every  subsequent  transfer  agent  for  any  shares  of the Company's
capital stock issuable upon the exercise of any of the rights of  purchase  will
be  irrevocably  authorized  and directed at all times to reserve such number of
authorized shares as shall be requisite for such purpose.  The Company will keep
a copy of this Agreement on file with every transfer agent for any shares of the
Company's capital  stock  issuable  upon  the  exercise  of  the Warrants.  Each
transfer agent for the Common Stock is hereby irrevocably authorized to cause to
be issued from time to time the stock certificates required to honor outstanding
Warrants upon exercise thereof in accordance with the terms of  this  Agreement.
The   Company   will  supply  such  transfer  agent  with  duly  executed  stock
certificates for such purposes and will  provide or otherwise make available any
cash which may be payable as  provided  in  Section  12  hereof.   All  Warrants
surrendered  upon the exercise of the rights thereby evidenced shall be canceled
by the Warrant Agent and shall thereafter be delivered to the Company.  Promptly
after the Expiration Date, the  Warrant  Agent  shall certify to the Company the
aggregate number of Warrants then  outstanding,  and  thereafter  no  shares  of
Common Stock shall be subject to reservation in respect of such Warrants.

         The  Company  covenants  that  all  shares  issued upon exercise of the
Warrants will, upon issuance in accordance  with the terms of this Agreement, be
fully paid and nonassessable  and  free  from  all  taxes,  liens,  charges  and
security interests created by the Company with respect to the issuance thereof.

         9.2  Purchase  of  Warrants by the Company.  The Company shall have the
right, except as limited by law, to contract with individual holders of Warrants
to purchase or otherwise acquire Warrants at  such times, in such manner and for
such consideration as may be agreed upon with such holders.

         9.3 Cancellation of Warrants.  In the event the Company shall  purchase
or  otherwise  acquire  Warrants,  the  same shall thereupon be delivered to the
Warrant Agent and be canceled  by  the  Warrant  Agent and retired.  The Warrant
Agent shall cancel any Warrant surrendered for exchange, substitution,  transfer
or exercise in whole or in part.

         Section  1O  Warrant  Exercise  Price.   The  price  per share at which
Warrant Shares shall  be  purchasable  upon  exercise  of Warrants (the "Warrant
Price") shall be $1.54 per share, subject to adjustment pursuant to  Section  11
hereof.

         Section  11  Adjustment  of  Warrant  Price  and Number of Shares.  The
number and kind of securities purchasable upon the exercise of each Warrant, and
the Warrant Price, shall be  subject  to  adjustment  from time to time upon the
happening of certain events, as hereinafter described.

         11.1 Mechanical Adjustments.  The number of Warrant Shares  purchasable
upon  the  exercise  of  each  Warrant and the Warrant Price shall be subject to
adjustment as follows.

         (a)  If  the  Company  shall  (i)  issue  a  dividend  in,  or  make  a
distribution of,  shares  of  Common  Stock  to  holders  of  Common Stock, (ii)
subdivide its outstanding shares of Common stock, (iii) combine its  outstanding
shares  of  Common  Stock  into a small number of shares of Common Stock or (iv)
issue by reclassification of its shares  of Common Stock other securities of the
Company, the number of Warrant Shares purchasable upon exercise of each  Warrant
immediately  prior  thereto shall be adjusted so that the Holder of each Warrant
shall be entitled to receive  the  kind  and  number  of Warrant Shares or other
securities of the Company that he would have owned  or  have  been  entitled  to
receive  after  the  happening  of  any  of the events described above, had such
Warrant been exercised immediately prior to  the  happening of such event or any
record date  with  respect  thereto.   Any  adjustment  made  pursuant  to  this
paragraph  (a)  shall  become  effective immediately after the effective date of
such event retroactive to the record date, if any, for such event.

         (b) For purposes of any computation  under Section 12 and paragraph (e)
of this Section, the current or closing market price per share of  Common  Stock
at  any date shall be the average of the daily closing prices for 15 consecutive
trading days commencing 20  trading  days  before  the date of such computation.
The closing price for each day shall be the daily closing prices of  the  Common
Stock as reported on the composite transactions tape for the principal exchanges
on  which  the  Common  Stock  is  listed or admitted to trading (the "Composite
Tape").  The closing price for each day shall be the last sale price regular way
or, in case no such sale takes place on such day, the average of the closing bid
and asked prices regular way, in either  case as reported on the Composite Tape,
or, if the Common Stock is not reported on the Composite Tape, on the  principal
national  securities exchange on which the Common Stock is listed or admitted to
trading, or if the Common  Stock  is  not  listed  or admitted to trading on any
national securities exchange, the average of the highest reported bid and lowest
reported  asked  prices  on  the  National  Association  of  Securities  Dealers
Automated Quotation System ("NASDAQ"), or a similar  service  if  NASDAQ  is  no
longer  reporting  such information.  Although the Common Stock is not currently
listed on any exchange and  is  not  quoted  on NASDAQ, the foregoing provisions
will be applicable if the Common Stock is subsequently so listed or quoted.   If
on  any  date  at  which  determination of the current market price per share of
Common Stock is required the Common Stock is not guoted by any such service, the
current or closing market price per share of the Common Stock on such date shall
be determined by the Board  of  Directors  of  the  Company on the basis of such
quotations or other information as it in good  faith  considers  appropriate  or
such  other relevant evidence as may be appropriate under the circumstances, and
such determination, if made in good faith, shall be binding upon all Holders.

         (c) No adjustment in the number of Warrant Shares purchasable hereunder
shall be required unless such  adjustment  would require an increase or decrease
of at least one percent (1%) in the number of Warrant  Shares  purchasable  upon
the  exercise  of  each Warrant; provided, however, that any adjustments that by
reason of this paragraph  (c)  are  not  required  to  be  made shall be carried
forward and taken into account in any subsequent adjustment.   All  calculations
shall be made to the nearest one-thousandth of a share.

         (d) Whenever the number of Warrant Shares purchasable upon the exercise
of  each  Warrant  is adjusted as provided in paragraph (a) of this Section, the
Warrant Price  payable  upon  exercise  of  each  Warrant  shall  be adjusted by
multiplying such Warrant  Price  immediately  prior  to  such  adjustment  by  a
fraction,  the  numerator  of  which  shall  be  the  number  of  Warrant Shares
purchasable  upon  the  exercise  of  each  Warrant  immediately  prior  to such
adjustment, and the denominator of which shall be the number of  Warrant  Shares
so purchasable immediately thereafter.

         (e)  If  the  Company  shall  sell and issue shares of Common Stock, or
rights, options, warrants or  convertible  or exchangeable securities containing
the right to subscribe for or purchase shares of  Common  Stock  (excluding  (i)
shares,  rights,  options,  warrants  or  convertible or exchangeable securities
issued in any of the transactions  described in paragraph (a) above, (ii) shares
issuable upon exercise of stock options or shares of Common Stock granted or  to
be granted to employees or directors of the Company, (iii) the Warrant Shares or
(iv)  shares  issued  to  stockholders  of  any corporation that is acquired by,
merged into or becomes part of  the  Company  or  a subsidiary of the Company in
proportion to their stock holdings of such corporation immediately prior to such
merger, upon such merger) at a price per share of Common Stock  (determined,  in
the  case  of  such  rights,  options,  warrants  or convertible or exchangeable
securities, by dividing  (i)  the  total  amount  received  or receivable by the
Company in consideration of the sale  and  issuance  of  such  rights,  options,
warrants or convertible or exchangeable securities, plus the total consideration
payable  to  the  Company upon exercise, conversion or exchange thereof, by (ii)
the total number of  shares  of  Common  Stock  covered by such rights, options,
warrants or convertible or exchangeable securities) lower than the then  current
Warrant  Price  in  effect immediately prior to such sale and issuance, then the
Warrant Price shall be  reduced  to  a  price  (calculated  to the nearest cent)
determined by dividing (i) an amount equal to the  sum  of  (A)  the  number  of
shares  of  common Stock outstanding immediately prior to such sale and issuance
multiplied by  the  then  existing  Warrant  Price,  plus  (B) the consideration
received by the Company upon such sale and issuance, by (ii) the total number of
shares of Common Stock outstanding immediately after  such  sale  and  issuance.
Such  adjustment  shall  be made successively whenever such an issuance is made.
For the purposes of such adjustments, the shares of Common Stock that the holder
of any such rights, options,  warrants or convertible or exchangeable securities
shall be entitled to subscribe for or purchase shall be deemed to be issued  and
outstanding  as  of  the  date  of  such sale and issuance and the consideration
received by  the  Company  therefor  shall  be  deemed  to  be the consideration
received by the Company for such rights, options,  warrants  or  convertible  or
exchangeable  securities,  plus  the  consideration  or  premiums stated in such
rights, options, warrants or convertible  or  exchangeable securities to be paid
for the shares of Common Stock covered thereby.  If the Company shall  sell  and
issue  shares  of  Common  Stock, or rights, options, warrants or convertible or
exchangeable securities containing the right to subscribe for or purchase shares
of Common Stock,  for  a  consideration  consisting,  in  whole  or  in part, of
property other than cash or its equivalent, then in determining the  "price  per
share  of  Common  Stock"  and  the  "consideration received by the Company" for
purposes of the first sentence  of  this  paragraph  (e), the Board of Directors
shall determine, in its discretion, the fair value of such  property,  and  such
determination,  if made in good faith, shall be binding upon all Holders.  There
shall be no adjustment of the  Warrant  Price  pursuant to this paragraph (e) if
the amount of such adjustment shall  be  less  than  $0.10  per  Warrant  Share;
provided  however, that any adjustments that by reason of this provision are not
required to be made  shall  be  carried  forward  and  taken into account in any
subsequent adjustment.

         (f) For the purpose of this subsection 11.1, the term "shares of Common
Stock" shall mean (i) the class of stock designated as the Common Stock  of  the
Company at the date of this Agreement, or (ii) any other class of stock that may
be  subsequently  designated  as the Common Stock of the Company by the Board of
Directors in lieu of the  Common  Stock  as currently constituted.  In the event
that at any time, as a result of an adjustment made pursuant  to  paragraph  (a)
above,  the  Holders shall become entitled to purchase any shares of the Company
other than shares of Common Stock, thereafter the number of such other shares so
purchasable upon exercise of each Warrant  and  the Warrant Price of such shares
shall be subject to adjustment from time to time in a manner  and  on  terms  as
nearly  equivalent  as practicable to the provisions with respect to the Warrant
Shares contained in paragraph (a)  above,  and  the  provisions of Section 6 and
subsections 11.2 through 11.5, inclusive, with respect to  the  Warrant  Shares,
shall apply on like terms to any such other shares.

        11.2  Notice  of  Adjustment.   Whenever  the  number  of Warrant Shares
purchasable upon the exercise  of  each  Warrant  or  the  Warrant Price of such
Warrant Shares is adjusted as herein  provided,  the  Company  shall  cause  the
Warrant Agent promptly to give written notice (as provided in Section 19 hereof)
of  such  adjustment  or  adjustments  to  each  Holder and shall deliver to the
Warrant Agent a certificate  from  the  chief  financial  officer of the Company
setting forth the number of Warrant Shares purchasable upon the exercise of each
Warrant and the Warrant Price of such War- rant Shares  after  such  adjustment,
setting  forth  a  brief  statement  of  the facts requiring such adjustment and
setting  forth  the  computation  by  which  such  adjustment  was  made.   Such
certificate shall be conclusive evidence  of the correctness of such adjustment.
The Warrant Agent shall be entitled to rely on such  certificate  and  shall  be
under  no duty or responsibility with respect to any such certificate, except to
exhibit the same,  from  time  to  time,  to  any  Holder desiring an inspection
thereof during reasonable business hours.  The Warrant Agent shall  not  at  any
time be under any duty or responsibility to any Holders to determine whether any
facts  exist  that may require any adjustment of the Warrant Price or the number
of Warrant Shares or other stock or property purchasable on exercise thereof, or
with respect to the nature or extent  of  any such adjustment when made, or with
respect to the method employed in making such adjustment.

        11.3 No Adjustment for Dividends.   Except  as  provided  in  subsection
11.1,  no  adjustment  in respect of any dividends paid on shares of any capital
stock of the Company shall be  made  during  the  term  of a Warrant or upon the
exercise of a Warrant.

         11.4   Preservation   of   Purchase   Rights   Upon   Reclassification.
Consolidation. etc.  In case of any consolidation or merger of the Company  with
or  into  another  corporation  or  in case of any sale or conveyance to another
corporation of the property of the Company as an entirety or substantially as an
entirety, the Company or such  successor  or purchasing corporation, as the case
may be, shall execute with the Warrant Agent an agreement, satisfactory in  form
to  the Warrant Agent and executed and delivered to the Warrant Agent, that each
Holder shall have the right thereafter  (but  prior to the Expiration Date) upon
payment of the Warrant Price in effect immediately  prior  to  such  action,  to
purchase  upon  exercise of each Warrant the kind and amount of shares and other
securities and property  that  he  would  have  owned  or  have been entitled to
receive after the happening of such consolidation, merger,  sale  or  conveyance
had  such  Warrant  been  exercised  immediately  prior  to  such  action.  Such
agreement shall provide for adjustments  that  shall  be as nearly equivalent as
may be practicable to the adjustments provided for in this Section 11 and  shall
also  provide  for  the  express  assumption by any such successor or purchasing
company of the due and  punctual  performance  and  observance of each and every
covenant and condition of this Agreement to be performed  and  observed  by  the
Company.   The  Company shall mail by first class mail, postage prepaid, to each
Holder, notice of the execution of  any  such agreement.  The provisions of this
subsection 11.4 shall similarly apply  to  successive  consolidations,  mergers,
sales   or   conveyances.    The  Warrant  Agent  shall  be  under  no  duty  or
responsibility to determine the correctness  of  any provisions contained in any
such agreement relating either to the kind or amount of shares of stock or other
securities or property receivable upon exercise of Warrants or with  respect  to
the method employed and provided therein for any adjustments.

         11.5  Statement  on  Warrants.   Irrespective of any adjustments in the
Warrant Price or the number or  kind  of shares purchasable upon the exercise of
the Warrants, Warrant Certificates theretofore or thereafter issued may continue
to express the same price and number and kind of shares as  are  stated  in  the
Warrant Certificates initially issuable pursuant to this Agreement.

         Section  12 Fractional Interests.  The Company shall not be required to
issue fractional Warrant Shares on the  exercise  of Warrants.  If more than one
Warrant shall be presented for exercise in full at the same  time  by  the  same
Holder,  the  number  of  full  Warrant  Shares  that shall be issuable upon the
exercise thereof shall be  computed  on  the  basis  of  the aggregate number of
Warrant Shares purchasable on exercise of the Warrants  so  presented.   If  any
fraction of a Warrant Share would, except for the provisions of this Section 12,
be  issuable  in the exercise of any Warrant (or specified portion thereof), the
Company shall calculate and pay  an  amount  in  cash  equal to the then current
market price per Warrant Share (as defined in Section 11.1(b) above)  multiplied
by such fraction.

         Section 13 No Rights as Stockholder;  Notices to Holders.  No holder of
Warrants,  as  such,  shall  be  entitled  to vote on or be deemed the holder of
Common Stock or any other securities  of  the  Company  which may at any time be
issuable on the exercise  of  Warrants  for  any  purpose,  nor  shall  anything
contained  in  this Agreement be construed to confer upon a Holder, as such, any
of the rights of a  stockholder  of  the  Company  or  any right to vote for the
election of directors or upon  any  matter  submitted  to  stockholders  at  any
meeting  thereof,  or  give or withhold consent to any corporate action (whether
upon any recapitalization, issue of  stock, reclassification of stock, change of
par value or change of stock to no par value, consolidation, merger,  conveyance
or  otherwise)  or  to  receive  notice  of  meetings or other actions affecting
stockholders (except as provided below), or to receive dividends or subscription
rights or otherwise, until the Warrants shall have been exercised and the Common
Stock purchasable upon the  exercise  thereof  shall  have become deliverable as
provided in this Agreement.  If, however, at any time prior to the expiration of
the Warrants and prior to their exercise, any  of  the  following  events  shall
occur:

         (a)  the  Company  shall declare any dividend payable in any securities
(other than additional shares of Common  Stock)  upon its shares of Common Stock
or make any distribution (other than a cash dividend)  to  the  holders  of  its
shares of Common Stock; or

         (b)  any capital reorganization of the Company, any reclassification or
recapitalization of the capital stock of  the  Company be any transfer of all or
substantially all the assets of the Company to, or consolidation  or  merger  of
the Company with or into, any other corporation; or

         (c)  a  voluntary or involuntary dissolution, liquidation or winding up
of the Company shall be proposed; then  in  any  one or more of said events, the
Company shall give notice in writing of such event to the Warrant Agent and  the
Holders  as provided in Section 19 hereof, such giving of notice to be completed
at least 20 days prior to the date fixed as a record date or the date of closing
the transfer books for the  determination  of  the stockholders entitled to such
dividend, or distribution, or for the determination of stockholders entitled  to
vote on such reorganization, recapitalization, transfer of assets, consolidation
or  merger  or  on  such  proposed dissolution, liquidation or winding up.  Such
notice shall specify such record  date  or  the  date of closing of the transfer
books, as the case may be.  Failure to mail such notice or any defect therein or
in the mailing thereof shall not affect the validity  of  any  action  taken  in
connection    with   '   such   dividend,   distribution,   or   reorganization,
recapitalization,  transfer  of  assets,  consolidation  or  merger  or  on such
proposed dissolution, liquidation or winding up.

         Section 14 Disposition of Proceeds on Exercise of Warrants:  Inspection
of Warrant Agreement.  The Warrant Agent shall account promptly to  the  Company
with  respect  to  Warrants  exercised  and  currently  pay  to  the Company all
immediately available funds received by  the  Warrant  Agent for the purchase of
the Warrant Shares through the exercise of such  Warrants.   The  Warrant  Agent
shall,  upon  request  of  the Company from time to time, deliver to the Company
such complete reports of registered ownership  of the Warrants and such complete
records or transactions with respect to the Warrants and the  shares  of  Common
Stock  as  the Company may request.  The Warrant Agent shall also make available
to the Company for inspection by the Company's agents or employees, from time to
time as the Company may  request,  such  original  books of accounts and records
maintained by the Warrant Agent in connection with the issuance and exercise  of
Warrants  hereunder,  such  inspection to occur at the Warrant Agent's principal
office in Dallas,  Texas  as  specified  in  Section  19, during normal business
hours.

         The Warrant Agent shall keep copies of this Agreement  and  any  notice
given  or  received  hereunder  available  for  inspection by the Holders during
normal business hours at its principal office in Dallas, Texas.

         Section 15 Merger or Consolidation or  Change of Name of Warrant Agent.
Any corporation into which the Warrant Agent may be merged or with which it  may
be  consolidated,  or any corporation resulting from any merger or consolidation
to which the Warrant Agent shall  be  a  party, or any corporation succeeding to
the corporate trust business of the Warrant Agent, shall be the successor to the
Warrant Agent hereunder without the execution or filing  of  any  paper  or  any
further  act  on  the  part  of  any  of  the  parties hereto provided that such
corporation must be eligible for appointment  as a successor Warrant Agent under
the provisions of Section 17 hereof.  If at  the  time  such  successor  to  the
Warrant  Agent  shall succeed to the agency created by this Agreement any of the
Warrants shall have been countersigned but  not delivered, any such successor to
the Warrant Agent may adopt the countersignature of the original  Warrant  Agent
and  deliver  such  Warrants  so  countersigned;  and if at that time any of the
Warrants shall not have been  countersigned,  any successor to the Warrant Agent
may countersign such Warrants either in the  name  of  the  predecessor  Warrant
Agent  or  in  the  name  of  the successor Warrant Agent; and in all such cases
Warrants shall  have  the  full  force  provided  in  the  Warrants  and in this
Agreement.

         If at any time the name of the Warrant Agent shall be  changed  and  at
such  time  any of the Warrants shall have been countersigned but not delivered,
the Warrant Agent  may  adopt  the  countersignatures  under  its prior name and
deliver such Warrants so countersigned; and if at that time any of the  Warrants
shall  not  have  been  countersigned,  the  Warrant  Agent may countersign such
Warrants either in its prior name or in  its changed name; and in all such cases
such Warrants shall have the full force provided in the  Warrants  and  in  this
Agreement.

         Section  16 Concerning the Warrant Agent.  The Warrant Agent undertakes
the duties and obligations imposed  by  this  Agreement upon the following terms
and conditions, by all of which the Company and the Holders, by their acceptance
of Warrants, shall be bound:

         16.1 Correctness of Statements.  The statements contained herein and in
the Warrants shall be taken as statements of the Company and the  Warrant  Agent
assumes  no responsibility for the correctness of any of the same except such as
describe the Warrant Agent or action taken by it.

         16.2 Breach of Covenants.  The  Warrant  Agent shall not be responsible
for any failure of the Company to comply with any of the covenants contained  in
this Agreement or in the Warrants to be complied with by the Company.

         16.3 Performance of Duties.  The Warrant Agent may execute and exercise
any  of  the  rights or powers hereby vested in it or perform any duty hereunder
either itself or by or through its  attorneys or agents (which shall not include
its employers) and shall not be responsible for the misconduct or negligence  of
any agent appointed with due care.

         16.4  Reliance  on  Counsel.  The Warrant Agent may consult at any time
with legal counsel satisfactory to it  (who  may be counsel for the Company) and
the Warrant Agent shall incur no liability or responsibility to the  Company  or
to  any  Holder  in  respect  of  any  action  taken,  suffered or omitted by it
hereunder in good faith and in accordance with the opinion or the advice of such
counsel provided that such counsel shall have been selected with due care.

         16.5 Proof of Actions Taken.  Whenever in the performance of its duties
under this Agreement the Warrant Agent shall deem it necessary or desirable that
any fact or matter be proved  or  established  by the Company prior to taking or
suffering any action hereunder, such fact or matter (unless  other  evidence  in
respect thereof be herein specifically prescribed) may be deemed conclusively to
be  proved and established by a certificate signed by the Chairman of the Board,
the President, any Vice President,  the  Secretary or any Assistant Secretary of
the Company and delivered to the Warrant Agent; and such  certificate  shall  be
full authorization to the Warrant Agent for any action taken or suffered in good
faith  by  it  under  the  provisions  of  this  Agreement in reliance upon such
certificate.

         16.6  Compensation.   The  Company  agrees  to  pay  the  Warrant Agent
reasonable compensation as set forth  in  the  attached  fee  schedule  for  all
services  rendered  by  the Warrant Agent in the performance of its duties under
this Agreement, to reimburse the  Warrant  Agent for all out-of-pocket expenses,
taxes and governmental charges incurred by the Warrant Agent in the  performance
of  its duties under this Agreement, and to indemnify the Warrant Agent and save
it harmless against  any  and  all  liabilities,  including judgments, costs and
counsel fees, for  anything  done  or  omitted  by  the  Warrant  Agent  in  the
performance of its duties under this Agreement except as a result of the Warrant
Agent's negligence or misconduct.

         16.7 Legal Proceedings.  The Warrant Agent shall be under no obligation
to  institute  any  action, suit or legal proceeding or to take any other action
likely in its reasonable judgment to involve material expense unless the Company
or one or more Holders shall  furnish the Warrant Agent with reasonable security
and indemnity for any  costs  and  expenses  that  may  be  incurred,  but  this
provision shall not affect the power of the Warrant Agent to take such action as
the Warrant Agent may consider proper, whether with or without any such security
or  indemnity.   All  rights  of action under this Agreement or under any of the
Warrants may be enforced by the  Warrant  Agent without the possession of any of
the Warrants or the production thereof at any trial or other proceeding relative
thereto, and any such action, suit or proceeding instituted by the Warrant Agent
shall be brought in its name as Warrant Agent,  and  any  recovery  of  judgment
shall  be  for the ratable benefit of the Holders, as their respective rights or
interests may appear.

         16.8 Other Transactions  in  Securities  of  the  Company.  The Warrant
Agent and any stockholder, director, officer or employee of  the  Warrant  Agent
may  buy, sell or deal in any of the Warrants or other securities of the Company
or become pecuniarily interested in any  transaction in which the Company may be
interested, or contract with or lend money to the Company or  otherwise  act  as
fully  and  freely  as  though  it  were not Warrant Agent under this Agreement.
Nothing herein  shall  preclude  the  Warrant  Agent  from  acting  in any other
capacity for the Company or for any other legal entity.

         16.9 Liability of Warrant Agent.  The Warrant Agent shall act hereunder
solely as agent, and its duties shall be determined  solely  by  the  provisions
hereof.   The  Warrant  Agent shall not be liable for anything that it may do or
refrain from  doing  in  connection  with  this  Agreement  except  for  its own
negligence  or  misconduct.   Anything  in  this  Agreement  to   the   contrary
notwithstanding,  in  no event shall Chemical be liable for special, indirect or
consequential loss or damage of any  kind whatsoever (including, but not limited
to, lost profits), even if Chemical has been advised of the likelihood  of  such
loss or damage and regardless of the form of action.

         16.10  Reliance  on  Documents.   The  Warrant Agent will not incur any
liability or responsibility to the Company or to any Holder for any action taken
in reliance on any notice,  resolution,  waiver, consent, order, certificate, or
other paper, document or instrument reasonably believed by it to be genuine  and
to have been signed, sent or presented by the proper party or parties.

         16.11  Validity of Agreement.  The Warrant Agent shall not be under any
responsibility in respect of the validity of this Agreement or the execution and
delivery hereof (except the due  execution  hereof  by  the Warrant Agent) or in
respect of the validity or execution of any Warrant (except its countersignature
thereof); nor shall the Warrant Agent by any act hereunder be deemed to make any
representation or warranty as to the authorization or reservation of any Warrant
Shares (or other stock) to be issued pursuant to this Agreement or any  Warrant,
or  as  to  whether  any  Warrant  Shares (or other stock) will, when issued, be
validly issued, fully paid and nonassessable, or  as to the Warrant Price or the
number or amount of  Warrant  Shares  or  other  securities  or  other  property
issuable upon exercise of any Warrant.

         16.12   Instructions   from  Company.   The  Warrant  Agent  is  hereby
authorized and directed to accept  instructions  with respect to the performance
of its duties hereunder from the Chairman of the Board, the President, any  Vice
President, the Secretary or any Assistant Secretary of the Company, and to apply
to  such  officers for advice or instructions in connection with its duties, and
shall not be liable for any action taken  or  suffered to be taken by it in good
faith in accordance with instructions of any such officer or officers.

         Section 17 Change of Warrant Agent.  The Warrant Agent may  resign  and
be  discharged  from  its  duties  under this Agreement by giving the Company 30
days' notice in writing cf its  intention  to resign, but such resignation shall
take effect upon the appointment of a  successor  to  the  Warrant  Agent.   The
Warrant  Agent  may  be  removed  by  like  notice to the Warrant Agent from the
Company.  If the Warrant Agent shall  give  notice of its intention to resign or
shall be removed or shall otherwise become  incapable  of  acting,  the  Company
shall  appoint  a  successor to the Warrant Agent.  If the Company shall fail to
make such appointment within a period of  30 days after such removal or after it
has been notified in writing of such intended resignation or incapacity  by  the
resigning  or  incapacitated  Warrant  Agent,  or  as notified in writing by any
Holder (who shall with  such  notice  submit  his  Warrant for inspection by the
Company), then any Holder may apply to any court of competent  jurisdiction  for
the appointment of a successor to the Warrant Agent.  If at any time there shall
be  no warrant agent with respect to the Warrants, the Company shall perform the
duties of the Warrant Agent.  Any  successor warrant agent, whether appointed by
the Company or such a court, shall be a bank or trust company, in good standing,
incorporated under the laws of the United States of America or any state thereof
and having at the time of its appointment as warrant agent  a  combined  capital
and  surplus  of at least $10,000,000.  After appointment, the successor warrant
agent shall be vested with the  same powers, rights, duties and responsibilities
as if it had been originally named as Warrant Agent without further act or deed;
but the former Warrant Agent shall deliver and transfer to the successor warrant
agent any property at the time held by it hereunder, and execute and deliver any
further assurance, conveyance, act or deed necessary for the  purpose.   Failure
to  file  any  notice  provided  for  in this Section 17, however, or any defect
therein, shall not affect the legality or validity of the resignation or removal
of the Warrant Agent or the  appointment  of the successor warrant agent, as the
case may be.  In the event of such resignation or removal, the successor warrant
agent shall give to each Holder written notice (in accordance  with  Section  19
hereof)  of  such  removal  or  resignation  and  the  name  and address of such
successor warrant agent.

         Section 18 Identity of Transfer  Agent.  Forthwith upon the appointment
of any subsequent transfer agent for the Common Stock, or any  other  shares  of
the  Company's  capital  stock  issuable  upon the exercise of the Warrants, the
Company will file with the Warrant Agent  a statement setting forth the name and
address of such subsequent transfer agent.

         Section 19 Notices.  Any notice  pursuant  to  this  Agreement  by  the
Company  or  by  any Holder to the Warrant Agent, or by the Warrant Agent or any
Holder to the Company, shall  be  in  writing  and  shall be mailed first class,
postage prepaid, to be delivered (a) to the Company,  at  its  office  at  11111

Warrant Agent to the Holders shall be in  writing  and  shall  be  mailed  first
class,  postage  prepaid,  or  delivered  to  such  Holders  at their respective
addresses on the books of  the  Warrant  Agent.  Notice shall be effective three
days after mailing or upon delivery.

         Section 20 Supplements and Amendments.  The  Company  and  the  Warrant
Agent  may  from time to time supplement or amend this Agreement, without notice
to or the approval of any Holder,  in  order to cure any ambiguity or to correct
or  supplement  any  provision  contained  herein  that  may  be  defective   or
inconsistent with any other provision herein, or to make any other provisions in
regard  to  matters  or  questions  arising  hereunder  that the Company and the
Warrant Agent may deem necessary or desirable and that shall not be inconsistent
with the provisions of  the  Warrants  and  that  shall not adversely affect the
interests of the Holders in any material respect.

         Section 21 Successor.  All covenants and provisions of  this  Agreement
by  or  for the benefit of the Company or the Warrant Agent shall bind and inure
to the benefit of their respective successors and assigns hereunder.

         Section 22 APPLICABLE  LAW.   THIS  AGREEMENT  AND  EACH WARRANT ISSUED
HEREUNDER SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE  SUBSTANTIVE
LAWS  OF  THE STATE OF TEXAS, WITHOUT GIVING EFFECT TO PRINCIPLES OF CONFLICT OF
LAWS.

         Section 23 Benefits of this Agreement.  Nothing in this Agreement shall
be construed to give to any  person  or  corporation other than the Company, the
Warrant Agent and the Holders any legal or  equitable  right,  remedy  or  claim
under  this  Agreement;  but  this Agreement shall be for the sole and exclusive
benefit of the Company, the Warrant Agent and the Holders.

of counterparts and each of such counterparts shall for all purposes  be  deemed
to  be  an original, and all such counterparts shall together constitute but one

         THIS CERTIFIES THAT,  for  value  received,  __________  or  registered
assigns, is the registered holder of the number of Class B warrants ("Warrants")
set  forth  above.   Each  Warrant  entitles the holder thereof to purchase from

"Company"), subject to the terms and conditions set forth hereinafter and in the
Warrant Agreement hereinafter referred to, one fully paid and  non-assess-  able
share  of  Common  Stock,  par value $.01 per share, of the Company (hereinafter
called the "Common  Stock"),  upon  presentation  and  surrender of this Warrant
Certificate, with the Form of Election  to  Purchase  duly  executed,  with  the
instructions for the registration and delivery of Common Stock filled in, at any
time  at  or  prior  to  5:00  P.M.,  New York time on December 22, 1996, at the
offices of Chemical Shareholder Services Group,  Inc., Warrant Agent of the Com-
pany (hereinafter called the  "Warrant  Agent")  in  Dallas,  Texas  or  of  its
successor  warrant  agent  or,  if  there  be no successor warrant agent, at the
corporate offices of the  Company,  and  upon  payment  of the Warrant Price (as
hereinafter defined) and any applicable taxes.  The price  per  share  at  which
Common  Stock  shall  be  purchasable  upon  exercise  of Warrants (the "Warrant
Price") is $1.54 per share.  The Warrant Price and the number and kind of shares
of  stock  of  the  Company  purchasable  upon  the  exercise  of  the  Warrants
represented hereby are subject to modification and adjustment upon the happening
of certain events set forth in the Warrant Agreement.

         This Warrant Certificate is subject to all of the terms, provisions and
conditions of the Warrant Agreement, dated  as of October 29, 1993 (the "Warrant
Agreement"), between the Company and the Warrant Agent with respect to  Class  B
Warrants  to  purchase  399,917  shares  of Common Stock, to all of which terms,
provisions and conditions  the  registered  holder  of  this Warrant Certificate
consents by acceptance hereof.  The Warrant  Agreement  is  hereby  incorporated
herein  by  this  reference and made a part hereof.  Reference is hereby made to
the Warrant Agreement  for  a  full  description  of  the  rights, limitation of
rights, obligations, duties and immunities hereunder of the Warrant  Agent,  the
Company  and  the  registered holders of the Warrant Certificate.  Copies of the
Warrant Agreement are available  for  inspection  at  the offices of the Warrant
Agent.

         As provided in the Warrant Agreement, payment of the aggregate  Warrant
Price  shall be made in lawful money of the United States of America in cash, by
cashier's check, certified check  or  bank  draft  payable  to  the order of the
Company.

         The Company shall not be required upon the  exercise  of  the  Warrants
evidenced  by  this  Warrant Certificate to issue fractions of shares, but shall
make adjustment therefor in cash  on  the  basis  of the current market price of
shares of Common Stock for any fractional interest (computed as provided in  the
Warrant Agreement), all as provided in the Warrant Agreement.  In no event shall
the Company be required to issue fractions of Warrants.

         This  Warrant  Certificate, with or without other Warrant Certificates,
upon surrender to the  Warrant  Agent,  any  successor  warrant agent or, in the
absence of any successor warrant agent, at the corporate offices of the Company,
may be exchanged for another Warrant Certificate or Certificates  evidencing  in
the  aggregate  the  same  number  of  Warrants  as  the  Warrant Certificate or
Certificates  so  surrendered.   If  the  Warrants  evidenced  by  this  Warrant
Certificate shall be exercised in part,  the  holder hereof shall be entitled to
receive upon  surrender  hereof  another  Warrant  Certificate  or  certificates
evidencing the number of Warrants not so exercised.

         No  holder  of  this Warrant Certificate, as such, shall be entitled to
vote on or be deemed the holder  of  Common Stock or any other securities of the
Company which may at any time  be  issuable  on  the  exercise  hereof  for  any
purpose,  nor  shall  anything  contained  in the Warrant Agreement or herein be
construed to confer upon the holder of this Warrant Certificate, as such, any of
the rights of a stockholder of the Company or any right to vote for the election
of directors  or  upon  any  matter  submitted  to  stockholders  at any meeting
thereof, or give or withhold consent to any corporate action (whether  upon  any
recapitalization, issue of stock, reclassification of stock, change of par value
or  change  of  stock  to  no  par  value,  consolidation, merger, conveyance or
otherwise)  or  to  receive  notice  of  meetings  or  other  actions  affecting
stockholders (except  as  provided  in  the  Warrant  Agreement),  or to receive
dividends or subscription rights or otherwise, until the Warrants  evidenced  by
this  Warrant  Certificate  shall  have  been  exercised  and  the  Common Stock
purchasable upon the exercise thereof  shall have become deliverable as provided
in the Warrant Agreement.

         If this Warrant Certificate shall be surrendered  for  exercise  within
any  period  during  which  the transfer books for the Company's Common Stock or
other class of stock purchasable upon  the exercise of the Warrants evidenced by
this Warrant Certificate are closed, the Company shall not be required  to  make
delivery  of  certificates  for  shares purchasable upon such exercise until the
date of the reopening of said transfer books.

         Each holder of this Warrant  Certificate by accepting the same consents
and agrees with the Company, the Warrant Agent, and with every other holder of a
Warrant Certificate that:

         (a) this Warrant Certificate is transferable only on the registry books
of the Warrant Agent; and

         (b) the Company and the Warrant Agent may deem and treat the person  in
whose  name  this  Warrant  Certificate  is registered as the absolute, true and
lawful owner hereof for all purposes whatsoever, and neither the Company nor the
Warrant Agent shall be affected by any notice to the contrary.

         The Company will pay  any  documentary  stamp taxes attributable to the
issuance of Common Stock upon the exercise of Warrants evidenced by this Warrant
Certificate; provided, that the Company shall not be required to  pay  any  such
taxes that may be payable in respect of any transfer involved in the issuance of
any  Common Stock, Warrants or Warrant Certificates in a name other than that of
the registered holder of Warrants evidenced by this Warrant Certificate, and the
Company shall not be required  to  issue  or deliver such certificates unless or
until the person or persons requesting issuance thereof shall have paid  to  the
Company  the amount of such tax or shall have established to the satisfaction of
the Company that such tax has been paid.

         This Warrant Certificate  shall  not  be  valid  or  obligatory for any
purpose until it shall have been countersigned by the Warrant Agent.

                  WARRANT ASSUMPTION AND CONVERSION AGREEMENT


     THIS WARRANT ASSUMPTION AND CONVERSION  AGREEMENT, dated as of ___________,
1996 (the "Agreement"), is made by and between TESORO PETROLEUM  CORPORATION,  a
Delaware  Corporation  ("Parent"),  COASTWIDE  ENERGY  SERVICE, INC., a Delaware
corporation  ("Company")  and  CHEMICAL  SHAREHOLDER  SERVICES  GROUP,  INC.,  a
national banking association, as warrant agent (the "Warrant Agent").

     WHEREAS, the respective  Board  of  Directors  of  Parent, CNRG Acquisition
Corporation (the "Sub") and Coastwide Energy Services, Inc. (the "Company") have
approved a merger of the Company into Sub upon terms and conditions contained in
an Agreement and Plan of Merger dated as  of  November  20,  1995  (the  "Merger
Agreement") by and among the Parent, the Sub and the Company;

     WHEREAS,  the  Company  and  the  Warrant Agent have entered into a Warrant
Agreement dated September 30, 1993  (the "Warrant Agreement") providing that the
Warrant Agent shall act  on  behalf  of  the  Company  in  connection  with  the
issuance,  transfer,  exchange  and  replacement of the Warrant Certificates (as
defined in the Warrant Agreement) in  respect of the Company's issuance of Class
B warrants (the "Warrants"), and the exercise of the Warrants;

     WHEREAS, Section 2.2(i) of the Merger Agreement provides that Parent  shall
enter  into  an  amended  Warrant  Agreement with the Warrant Agent, and it is a
condition to the obligation of the Company to effect the Merger under the Merger
Agreement that the Parent shall have  assumed the Warrants at the Effective Time
of the Merger (as defined in the Merger Agreement);

     WHEREAS, the Warrant Agreement provides, inter alia, that in the  event  of
any  merger  of  the  Company with or into another corporation, the successor or
purchasing corporation  shall  execute  with  the  Warrant  Agent  an agreement,
satisfactory in form to the Warrant Agent and  executed  and  delivered  to  the
Warrant  Agent, that each registered owner of the Warrants ("Holder") shall have
certain rights thereafter;

     NOW, THEREFORE, it is hereby agreed;

1.   Warrants.  Except as the  Warrants  may  otherwise  be adjusted as provided
herein, the Warrants are subject to all the terms and conditions included in the
original grant thereof.

2.   Assignment, Assumption and Conversion.  As of the  Effective  Time  of  the
Merger,  Parent  hereby  agrees  that  at the Effective Time, it will assume the
obligations of the Company under the  Warrant Agreement, and further agrees that
each Holder (except for the  Company  or  any  wholly-owned  subsidiary  of  the
Company,  or  the  Parent,  Sub or any wholly-owned subsidiary of Parent or Sub)
shall have the  right  (prior  to  the  expiration  date  of the Warrants), upon
payment of the Warrant Price (as that term is defined in the Warrant Agreement),
to purchase upon exercise of each Warrant the number of shares of Parent  Shares
(as  that  term  is  defined  in the Merger Agreement) and cash that such Holder
would have been entitled to receive at  the  Effective Time of the Merger if the
Warrant had been exercised immediately prior thereto.

3.   Except as the Warrant Agreement may otherwise be  modified  or  amended  by
this  Agreement, the Parent and the Warrant Agent hereby agree that on and after
the Effective Time of the Merger,  each  shall  have the same rights, duties and
obligations (i) with respect to the Parent, as the Company had under the Warrant
Agreement, and (ii) with respect to the Warrant Agent, as the Warrant Agent  had
under the Warrant Agreement.

4.   Parent  agrees  that  the  number  and  kind of securities purchasable upon
exercise of each Warrant and the  Warrant  Price  shall be adjusted from time to
time upon the happening of certain events on as  nearly  equivalent  as  may  be
practicable  basis  to the adjustments provided for in Section 11 of the Warrant
Agreement.

5.   Parent agrees that it will at  all  times reserve and keep available out of
the aggregate of its authorized but unissued Common Stock, the  full  number  of
shares  of  Common  Stock  then  deliverable  upon  exercise  of the outstanding
Warrants, as provided in Section 9.1 of the Warrant Agreement.

6.   Form of Agreement.  The Warrant  Agent hereby agrees that this Agreement is
in form satisfactory to  it,  and  by  the  signature  of  its  duly  authorized
representative hereon acknowledges that it has received an executed copy of this
Agreement.

     (a)Parent will at the  Effective  Time,  mail  by first class mail, postage
prepaid, to each Holder, notice of the execution of this Agreement.

8.  Further Amendments.  Any and all of the terms and conditions of the  Warrant
Agreement  are  hereby  amended and modified wherever necessary, even though not
specifically  addressed  herein,  so  as   to  conform  to  the  amendments  and
modifications contained in this Agreement.

                      which  such  Holder  is not entitled to receive under this

                      amounts remaining unpaid on  account  of the principal of,
                      premium, if any, and interest on such Senior Indebtedness,

                      full, after giving effect to  any  concurrent  payment  or
                      distribution,  or  provision  therefor,  to the holders of
                      such Senior Indebtedness.

          (c)  Subrogation of the Debenture.  Subject  to the payment in full of
               all Senior Indebtedness,  the  rights  of  the  Holder  shall  be

               receive payments or distributions of cash, property or securities
               of  the  Company  applicable  to  Senior  Indebtedness  until the
               principal of and interest on the Debenture shall be paid in full;
               and,  for  the  purposes  of  such  subrogation,  no  payments or
               distributions to the holders of Senior Indebtedness of any  cash,
               property  or  securities  to  which  the Holder would be entitled
               except for the provisions of this Section 4, and no payment over,
               pursuant to the provisions of  this  Section 4, to the holders of
               Senior Indebtedness, and the Holder, be deemed to be  payment  by
               the  Company  to or on account of the Senior Indebtedness.  It is
               understood that the provisions  of  this  Section  4 are, and are
               intended solely for the purpose of, defining the relative  rights
               of  the  Holder  on  the  one  hand,  and  the  holder  of Senior
               Indebtedness on the other hand.

               Nothing contained  in  this  Section  4  or  elsewhere  herein is
               intended  to  or  shall  impair,  as  between  the  Company,  its
               creditors other than the holders of Senior Indebtedness, and  the
               Holder,  the  obligation  of  the  Company, which is absolute and
               unconditional, to pay to the Holder the principal of and interest
               on the Debenture  as  and  when  the  same  shall  become due and
               payable in accordance with the terms hereof, or is intended to or
               shall affect  the  relative  rights  of  the  holders  of  Senior
               Indebtedness,  nor  shall anything herein prevent the Holder from
               exercising all  remedies  otherwise  permitted  by applicable law
               upon default hereunder, subject to the rights, if any, under this
               Section 4 of the holders of Senior  Indebtedness  in  respect  of
               cash,  property  or  securities  of the Company received upon the
               exercise of any such remedy.

               refereed to in this Section 4, the Holder shall  be  entitled  to
               rely  upon  any  order  or  decree made by any court of competent
               jurisdiction in which  such  dissolution, winding-up, liquidation
               or reorganization proceedings are pending, or  a  certificate  of
               the   receiver,   trustee  in  bankruptcy,  liquidating  trustee,
               custodian,  agent  or   other   party   making  such  payment  or
               distribution,  delivered  to  the  Holder,  for  the  purpose  of
               ascertaining  the  parties  entitled  to  participate   in   such
               distribution,  the  holders  of the Senior Indebtedness and other
               Innndebtedness of  the  Company,  the  amount  thereof or payable
               thereon, the amount or amounts paid or  distributed  thereon  and
               all other facts pertinent thereto or to this Section 4.

               The  terms  "paid  in full" and "payment in full" as used in this
               Section 4 with respect  to  Senior Indebtedness mean the receipt,
               in money or money's worth, of the principal amount of the  Senior
               Indebtedness  (and  any  premium  due  thereon) and full interest
               thereon to the date of  such  payment  of principal and all other
               amounts due to holders of Senior  Indebtedness  pursuant  to  the
               provisions of the instruments providing therefor.

               Nothing contained in this Section 4 shall impair the right of the
               Holder  to  convert this Debenture into shares of Common Stock as
               provided in Section 7 hereof.

     5.   Optional Prepayment,

          (a)  To the extent that the Company shall have funds legally available
               for such payment, the  Company  may  prepay  the Debenture at its
               option, in whole or from time to time in part, after July 1, 1997
               at a prepayment price equal to 105% of the principal amount  plus
               accrued interest to the prepayment date.

          (b)  If the Company proposes to prepay less than all of the Debentures
               outstanding  on  any  of  the  above  dates, the Debentures to be
               prepaid will be selected by lot  or  pro rata or any other method
               as may be determined by the Board of Directors of the Corporation
               to be fair.  Notice of prepayment shall be  mailed  at  least  15
               business  days  before  the  prepayment date to each Holder to be
               prepaid at its registered  address.   On and after the prepayment
               date interest shall cease to accrue on the Debentures or  portion
               thereof called for prepayment.

     6.   Conversion.   Each  Debenture  may  be  converted  at any time, at the
          option of the Holder, in whole or in part, into shares of Common Stock
          on the terms and conditions set forth in this Section 6.

          (a)  Each Debenture shall be convertible  at  the option of the Holder
               thereof, in whole or in part, at any time and from time to  time,
               as  hereinafter  provided,  into  that  number  of fully paid and
               nonassessable shares  of  Common  Stock  (as  such  shares may be
               constituted on the Conversion Date, as  hereinafter  defined)  as
               shall  be  obtained  by  dividing  the  principal  amount  of the
               Debenture outstanding on  the  Conversion  Date  which the Holder
               desires to convert by the Conversion Price, subject to adjustment
               as provided herein.  The  Conversion  Price  shall  be  4.25  per
               share.

          (b)  Before  any Holder of this Debenture shall be entitled to convert
               the same into Common Stock,  he  shall deliver the Debenture, for
               transfer and conversion, at the office of the Company,  at  11111
               Wilcrest  Green,  Suite  300, Houston, Texas 77042 (or such other
               office or agency of the  Company  as the Company may designate by
               notice in writing to the Holder) and shall give written notice to
               the Company that  he  elects  to  convert  all  or  part  of  the
               Debenture and shall state in writing therein the name or names in
               which  he  wishes the certificate or certificates of Common Stock
               to be issued.  Conversion shall  be  deemed to have been effected
               on the date when such delivery is made, and such date is referred
               to herein as the "Conversion Date."  The Company will, as soon as
               practicable  thereafter,  issue  and  deliver  to   such   Holder
               certificates for the number of shares of Common Stock to which he
               shall be entitled as aforesaid, together with cash in lieu of any
               fraction  of  a  share  as  hereinafter  provide  If  surrendered
               Debentures are converted only in part, the Company will issue and
               deliver to the Holder, a new Debenture representing the remaining
               balance of the Debenture.

          (c)  Adjustments  to  Conversion Price.  The Conversion Price shall be
               subject to adjustment as follows:

               (i)   Adjustments for Changes in Capital Stock. If the Company:

                     (1)  pays a dividend in  shares  of Common Stock to holders
                          of Common Stock;

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

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

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

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

                     then  the  Conversion  Price in effect immediately prior to
                     such action shall be  adjusted  so  that the Holder of this
                     Debenture thereafter converted may receive  the  number  of
                     shares  of  capital  stock of the Company which such Holder
                     would have owned immediately  following such action if such
                     Holder had converted the  Debenture  immediately  prior  to
                     such action.

                     For a dividend or distribution, the adjustment shall become
                     effective   immediately  after  the  record  date  for  the
                     dividend or distribution.   For  a subdivision, combination
                     or reclassification, the adjustment shall become  effective
                     immediately  after  the  effective date of the subdivision,
                     combination or reclassification.

                     If after  an  adjustment  the  Holder  upon  conversion may
                     receive shares of two or more classes of capital  stock  of
                     the  Company,  the  Board of Directors of the Company shall
                     determine the allocation  of  the adjusted Conversion Price
                     between or among the classes of capital stock.  After  such
                     allocation,  the Conversion Price of the classes of capital
                     stock shall thereafter  be  subject  to adjustment on terms
                     comparable  to  those  applicable  to  the   Common   Stock
                     contained in this Section 6(c).

               (ii)  Adjustment  for  Rights  Issue.   If the Company issues any
                     rights or warrants to  all  or substantially all holders of
                     shares of Common Stock entitling them after the record date
                     mentioned below to purchase  shares  of  Common  Stock  (or
                     securities  convertible  into  shares of Common Stock) at a
                     price per share (or  having  a  Conversion Price per share)
                     less than the Market Price per share on that  record  date,
                     the  Conversion  Price shall be adjusted in accordance with
                     rights or warrants.

                                         N x P
                                         -----
                     C'  =   C   x   O  +  M
                                     -------
                                     O  +  N
                     where:

                     C'   =    the adjusted Conversion Price.
                     C    =    the current Conversion Price.
                     O    =    the number of shares  of Common Stock outstanding
                               on the record date.
                     N    =    the number of additional shares of  Common  Stock
                               offered
                     P    =    the  offering  price  per share of the additional
                               shares.
                     M    =    the closing price  per  share  of Common Stock on
                               the record date.

                     The adjustment shall be made successively whenever any such
                     rights or warrants are issued, and shall  become  effective
                     immediately  after the record date for the determination of
                     stockholders entitled to  receive  the  rights or warrants.
                     If  all  of  the  shares  of  Common  Stock  or  securities
                     convertible into shares of Common  Stock  subject  to  such
                     rights or warrants have not been issued when such rights or
                     warrants  expire,  then the Conversion Price shall promptly
                     be readjusted to the  Conversion  Price which would then be
                     in effect had the adjustment  upon  the  issuance  of  such
                     rights  or  warrants  been  made on the basis of the actual
                     number of shares of Common Stock (or securities convertible
                     into shares of Common  Stock)  issued  upon the exercise of
                     such rights or warrants.

               (iii) Adjustment for Certain Other Distributions.  If the Company
                     distributes to all or substantially all holders  of  shares
                     of   Common  Stock  any  assets  or  general  evidences  of
                     indebtedness or any rights  or  warrants to purchase assets
                     or general evidences of indebtedness of the  Company,  then
                     the  Conversion  Price shall be adjusted in accordance with
                     the formula:


                      C'  =   C   x   (O x M) - F
                                      -----------
                                        (O x M)

                     where:

                     C'   =    the adjusted Conversion Price.
                     C    =    the current Conversion Price.
                     O    =    the number of shares  of Common Stock outstanding
                               on the record date.
                     M    =    the Market Price per share of Common Stock on the
                     F    =    the fair market  value  on  the  record  date  as
                               determined  by  the  Board  of  Directors  of the
                               assets  or  general   evidences  of  indebtedness
                               distributed.

                     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
                     stockholders entitled  to  receive  the distribution.  This
                     Section  does  not  apply  to  cash   dividends   or   cash
                     distribution Also, this Section does not apply to rights or
                     warrants referred to in Section 7(c)(ii).

               (iv)   Voluntary   Adjustment.   The  Company  at  any  time  may
                      decrease the Conversion  Price,  temporarily or otherwise,
                      by any amount but in no event shall such Conversion  Price
                      result  in  the  issuance  of Common Stock at a price less
                      than the par value of  the  Common  Stock at the time such
                      decrease is made.  Any decreased Conversion Price shall be
                      available for at least 20 days  from  the  date  on  which
                      notice  of  such decrease is filed by the Company with the
                      transfer agent for  the  Common  Stock,  and such decrease
                      shall be irrevocable  during  such  period.   The  Company
                      shall  notify  Holders  of the Debentures at least 15 days
                      prior to the date  on  which  the reduced Conversion Price
                      takes effect.

               (v)    Reorganization, Consolidation, Merger or  Sale.   In  case
                      the  Company  shall  consolidate  or  merge  into  or with
                      another corporation, or in case  the Company shall sell or
                      convey to any other person or persons all or substantially
                      all the  property  of  the  Company,  the  Holder  of  the
                      Debenture  shall  have the right thereafter to convert the
                      Debenture into the  kind  and  amount  of shares of stock,
                      other securities, cash and property receivable  upon  such
                      consolidation,  merger,  sale or conveyance by a holder of
                      the number  of  shares  of  Common  Stock  into which such
                      shares might have been converted immediately prior to such
                      consolidation, merger, sale or conveyance, and shall  have
                      no other conversion rights.  In any such event,  effective
                      provision shall be made, in the certificate or articles of
                      incorporation of the resulting or surviving corporation or
                      otherwise or in any  contracts  of  sale and conveyance so
                      that, so far as appropriate and as  nearly  as  reasonably
                      may be, the provisions set forth herein for the protection
                      of   the   conversion   rights  of  the  Debentures  shall
                      thereafter be made applicable.

               (vi)   Notice  of  Adjustment.    Upon   any  adjustment  of  the
                      Conversion Price, then and in each such case, the  Company
                      shall  give  written  notice thereof, by first class mail,
                      postage prepaid, addressed to the Holder at the address of
                      the Holder as shown  on  the  books  of the Company, which
                      notice shall state the  Conversion  Price  resulting  from
                      such  adjustment  and the increase or decrease, if any, in
                      the number of shares  purchasable  at  such price upon the
                      exercise  of  the  conversion  rights,  setting  forth  in
                      reasonable detail the method of calculation and the  facts
                      upon which such calculation is based.

                      that it will at all  times  reserve and keep available out
                      of the aggregate of its  authorized  but  unissued  Common
                      Stock  or its issued Common Stock held in its treasury, or
                      both, for  the  purpose  of  effecting  conversions of the
                      Debenture, the full number of shares of Common Stock  then
                      deliverable   upon   the  conversion  of  the  outstanding
                      principal amount of this Debenture; and if at any time the
                      number of authorized but  unissued  shares of Common Stock
                      shall not be sufficient to effect the  conversion  of  the
                      outstanding principal amount of the Debenture, the Company
                      will  take  such corporate action as may in the opinion of
                      its counsel be  necessary  to  increase its authorized but
                      unissued Common Stock to such number of shares as shall be
                      sufficient for that purpose.

               (ix)   Taxes on Conversion The  Company  will  pay  any  and  all
                      documentary  stamp  or  similar  issue  or  transfer taxes
                      payable in respect of the  issue  or delivery of shares of
                      Common Stock on conversion of the Debenture.

               (x)    Representations of the Holder.   In  connection  with  any
                      conversion hereunder, the Holder will supply an investor's
                      representation  letter  to the Company to the effect that:
                      (1) the shares  of  Common  Stock  are  being acquired for
                      investment only and not with a view  to  resale  or  other
                      distribution;  (2)  the  Company has made available to the
                      Holder and  its  representatives  all  documents  that the
                      Holder has requested relating to the Company and that  the
                      Holder  has  carefully  read  all  such documents; (3) the
                      Company  has  provided  answers  to  all  of  the Holder's
                      questions concerning the Company and the Common Stock; and
                      (4) such other provisions as  the  Company  deems  net  to
                      insure  that  it  may  issue  the  shares  of Common Stock
                      without registration pursuant  to  an applicable exemption
                      therefrom under the Securities Act  and  state  securities
                      laws.

          (d)  Exercise of the Conversion Rights or Transfer of the Debenture or
               Common  Stock.   Each  certificate  for  shares  of  Common Stock
               initially issued upon the exercise of the Conversion Rights shall
               be stamped or otherwise imprinted  with a legend in substantially
               the following form:

               "The transfer of the shares represented by  this  certificate  is
               subject  to  the  conditions  specified  in  the  8%  Convertible
               Subordinated  Debenture of Coastwide Energy Services, Inc. and no
               transfer of such shares  shall  be  valid or effective until such
               conditions have been fulfilled with respect to such transfer."

               The Holder of this Debeture or the shares of Common stock  issued
               upon  exercise  of  the Conversion Rights, by acceptance thereof,
               agrees to give written notice  to the Company before transferring
               the Debenture, or any shares of  Common  Stock  received  on  the
               exercise  of  the Conversion Rights, of the Holder's intention to
               do so, describing briefly the  manner of any proposed transfer of
               this  Debenture  or  shares  of  Common  stock  or  the  Holder's
               intention as to the disposition (and the intended method thereof)
               accompanied by an opinion of counsel (which opinion and choice of
               counsel shall be acceptable to the Company in the exercise of its
               reasonable discretion) opining that  the  proposed  transfer  and
               disposition  of the Debenture or of shares of Common Stock may be
               effected  without   registration   or   qualification  under  the
               Securities Act  or  state  securities  laws  applicable  to  such
               transfer  of  the  Debenture or the shares of Common stock issued
               with respect thereto.  No later than 15 days after receipt by the
               Company of  such  written  notice  and  opinion  of  counsel, the
               Company shall notify the Holder of the  Company's  acceptance  or
               rejection of the opinion of counsel and choice of counsel, and if
               the  Company  has accepted the same, the Holder shall be entitled
               to transfer this Debenture or such  shares of Common stock all in
               accordance with the terms of  the  notice  as  delivered  by  the
               Holder to the Company.

               If the Company rejects the  opinion  of  counsel or the choice of
               counsel as set forth above, the proposed transfer or  disposition
               may not be effected without registration or qualification of this
               Debenture  or the shares of Common stock issued upon the exercise
               of the Conversion Rights,  and  the  Company  shall so notify the
               Holder of such shares of Common Stock and  the  Holder  will  not
               transfer  such  securities unless they have been so registered or
               qualified.  The Company shall  not  register  or recognize, or be
               required to register or  recognize,  any  attempted  transfer  or
               disposition  of  this  Debenture  or  any  shares of Common stock
               issued upon conversion thereof in contravention of the Debenture.

          (e)  Fractional Shares:  Accrued Interest:   Partial  Conversion.   No
               fractional  shares  or scrip representing fractional shares shall
               be issued  upon  conversion  of  the  Debenture.   Instead of any
               fractional share of Common Stock that would otherwise be issuable
               upon conversion of the Debenture, the Company  will  pay  a  cash
               adjustment an amount equal to the price per share of Common Stock
               at  the close of business on the business day prior to the day of
               conversion.  In case the Debenture is converted in part only, the
               Company shall, upon such  conversion,  execute and deliver to the
               Holder at the expense of the Company, a  Debenture  in  aggregate
               principal  amount equal to the remaining principal balance of the
               Debenture  surrendered  and  interest  from  the  date  to  which
               interest has been paid on the Debenture so surrendered.

     7.   Registration Rights of Holder.

          (a)  If the Company at  any  time  after  the  date hereof proposes to
               register any shares of its Common stock under the Securities  Act
               (except  with  respect  to  any registration filed on Form S-8 or
               Form S-4 or such  other  similar  form  then  in effect under the
               Securities Act), it will each such  time  promptly  give  written
               notice  to (i) each holder (a "Registration Holder") of shares of
               Common Stock who has  received  such  shares of Common Stock upon
               conversion of the Debenture (such shares of  Common  Stock  being
               referred  to herein as "Registrable Shares") and (ii) each Holder
               of this Debenture,  of  its  intention  to  do  so  and, upon the
               written request  of  any  Registration  Holder  given  within  10
               calendar  days  after  receipt  of any such notice (which request
               shall state the intended method  of disposition of such shares by
               such Registration Holder), subject to the limitations  set  forth
               in subsection (g) below, the Company will use its best efforts to
               cause  Registrable  Shares hell by such Registration Holder as to
               which registration is so  requested,  to  be registered under the
               Securities Act, all to the extent requisite to permit the sale or
               other  disposition  (in  accordance  with  the  intended  methods
               thereof, as aforesaid) by such  Registration  Holder  (each  such
               registration under the Securities Act being referred to herein as
               a "Registration"); provided, however, that (A) the Company may at
               any  time withdraw or cease proceeding with any such Registration
               if it shall at the  same  time  withdraw or cease proceeding with
               the ration of such other shares of its  Common  Stock  originally
               proposed to be registered, and (B) if the managing underwriter of
               any  offering  shall  state  in  writing  that in its opinion the
               inclusion of such Registrable Shares in the proposed registration
               statement would have a  material  adverse  effect on the proposed
               offering, then at the Company's  request,  (x)  the  Registration
               Statement  shall  include only that number of Registrable Shares,
               if any, which the  managing  underwriter  believes may be offered
               without  causing  such  adverse  effect,  and   the   number   of
               Registrable  Shares  shall  be  allocated  among all Registration
               Holders requesting to participate  in such Registration Statement
               in proportion  (as  nearly  as  practicable)  to  the  number  of
               Registrable  Shares requested to be included by each Registration
               Holder or (y) the  Registration  Statement shall provide that the
               effective date of the Registration Statement with respect to  the
               Registrable  Shares  shall  be  delayed  for  ninety  (90)  days.
               Notwithstanding  anything  to  the contrary contained herein, the
               Company will not be obligated  alter  the date hereof to take any
               action to effect more than four  registrations  pursuant  to  the
               piggy-back registration rights contained in this Section 7.

          (b)  If  Registration Holders representing the aggregate more than 40%
               of the Negotiable Shares may  make written request to the Company
               to file, at Holder's election, a registration statement  covering
               the  Registrable  Securities  owned by such Holders.  The Company
               agrees upon receiving such written request to comply therewith as
               promptly  as  practicable  subject  to  the  following  terms and
               conditions:

               (i)  The  Company  shall  have the privilege of postponing action
                    for a reasonable period of  time (not exceeding 120 days) in
                    the event the filing would, in the reasonable opinion of the
                    Board of Directors, adversely affect  a  material  financing
                    project,  or  a  proposed or pending acquisition, merger, or
                    other corporate reorganization for  which  the Company is or
                    is expected to be a party.

               (ii) Upon receipt of such  written  request,  the  Company  shall
                    promptly  give  written notice thereof to all holders of the
                    Debenture at their addresses as  they appear on the books of
                    the Borrower, offering to include such Holder's  Registrable
                    Securities  in  a  registration statement to be filed by the
                    Company as provided herein,  if  such Holder makes a written
                    request therefor within 15 days after  the  giving  of  such
                    notice  by  the  Company; provided that if the Company shall
                    have elected under (i)  above  to postpone action under this
                    paragraph, it shall, in such notice, state  the  termination
                    date  of  the  period  of such postponement and the time for
                    Holders to make said  written  requests shall be extended to
                    15 days after said termination date.  The Company shall  not
                    be  required  to affect more than two registrations pursuant
                    to the demand registration rights provided herein.

          (c)  If and whenever the Company is  required pursuant to the terms of
               this Debenture to use its best efforts to effect the registration
               under the Securities Act of any Registrable Shares  held  by  the
               Registration Holder, the Company will, as promptly as possible:

               (i)    prepare   and   file  with  the  Securities  and  Exchange
                      Commission  (the  "SEC)   a  Registration  Statement  with
                      respect to  such  Registrable  Shares  and  use  its  best
                      efforts to cause such Registration Statement to become and
                      remain  effective  for  a  period  of at least ninety (90)
                      days;

               (ii)   prepare  and  file  with   the  SEC  such  amendments  and
                      supplement:,  to  such  Registration  Statement  and   the
                      prospectus   used   in  connection  therewith  as  may  be
                      necessary to  keep  such  Registration Statement effective
                      for ninety (90) days and to comply with the provisions  of
                      the  Securities  Ad  with  respect  to  the  sale or other
                      disposition of all  such Registration Holder's Registrable
                      Shares covered by such Registration Statement;

               (iii)  furnish to such Registration Holder such number of  copies
                      of  a  prospectus,  including a preliminary prospectus, in
                      conformity with the  requirements  of  the Securities Act,
                      and such other documents as such Registration  Holder  may
                      reasonably  request in order to facilitate the public sale
                      or other disposition of  such  Registrable Shares owned by
                      such Registration Holder;

               (iv)   register or qualify the Registrable Shares covered by such
                      Registration Statement under the securities  or  blue  sky
                      laws of such states as the Company shall determine, and do
                      any  and  all  other  acts  and  which may be necessary or
                      advisable to enable such Registration Holder to consummate
                      the public sale or other disposition in such jurisdictions
                      of such  Registrable  Shares  owned  by  such Registration
                      Holder; provided, however, that the Company shall  not  be
                      required   to   quality   to  do  business  as  a  foreign
                      corporation in any state where  it  is not then so called,
                      nor take any action  which  will  subject  it  to  general
                      service  or  process  in any state where it is not then so
                      subject;

               (v)    notify  such  Registration  Holder,  at  any  time  when a
                      prospectus  relating   to   such   Registration   Holder's
                      Registrable  Shares covered by such Registration Statement
                      is required  to  be  delivered  under  the  Securities Act
                      within the appropriate period  mentioned  in  clause  (ii)
                      above,  of the happening of any event as a result of which
                      the prospectus included in such Registration Statement, as
                      then in effect, includes an untrue statement of a material
                      fact or omits  to  state  a  material  fact required to be
                      stated therein or necessary to make the statements therein
                      not misleading in the  light  of  the  circumstances  then
                      existing,  and  at  such  Registration  Holder's  request,
                      prepare   and   finish   to  such  Registration  Holder  a
                      reasonable number  of  copies  of  a  supplement  to or an
                      amendment of such prose as may be necessary  so  that,  as
                      thereafter delivered to the purchasers of such Registrable
                      Shares,  such  prospectus  shall  Dot  include  an  untrue
                      statement  of a material fact or omits to state a material
                      fact required to be  stated  therein  or necessary to make
                      the statements therein not misleading in the light of  the
                      circumstances then existing; and

               (vi)   furnish,  at  such  Registration  Holder's request, on the
                      date that  such  Registration  Holder's Registrable Shares
                      are delivered to the underwriters for sale pursuant  to  a
                      registration  thereof  pursuant  to  this Debenture or, if
                      such  Registrable  Shares  are   not  being  sold  through
                      underwriters, on the date the Registration Statement  with
                      respect  to such securities becomes effective, an opinion,
                      dated such date, of  the  counsel representing the Company
                      for the purposes of such Registration  Statement,  stating
                      that  such  Registration  Statement  has  become effective
                      under the Securities Act and  that (1) to the knowledge of
                      such counsel, no stop order suspending  the  effectiveness
                      thereof  has  been  issued  and  no  proceedings  for that
                      purpose  have   been   instituted   or   are   pending  or
                      contemplated   under   the   Securities   Act;   (2)   the
                      Registration Statement, the related prospectus,  and  each
                      amendment  or supplement thereto, comply as to form in all
                      material respects with the  requirements of the Securities
                      Act and the applicable rules and regulations  of  the  SEC
                      thereunder  (except  that such counsel need not express an
                      opinion as to financial statements contained therein); (3)
                      the descriptions  in  the  Registration  Statement  or the
                      prospectus, or any amendment or supplement thereto, of all
                      legal documents or  instruments  present  the  information
                      required  to  be  shown  in compliance with the Securities
                      Act; and (4) such counsel  does  not  know of any legal or
                      governmental   proceedings,   pending   or   contemplated,
                      required to be described in the Registration Statement  or
                      prose  or  any  amendment  or supplement thereto, or to be
                      filed as exhibits to  the Registration Statement which are
                      not described and  filed  as  required;  such  opinion  of
                      counsel  shall additionally cover such other legal matters
                      with respect to the registration  in respect of which such
                      opinion is being given as  such  Registration  Holder  may
                      reasonably request.

          (d)  Expenses.  All expenses incurred by the Company in complying with

     WHEREAS,  the respective Board of Directors of Parent, Sub and Company have
approved a merger of the Company into Sub upon terms and conditions contained in
an Agreement and Plan  of  Merger  dated  as  of  November 20, 1995 (the "Merger
Agreement") by and among the Parent, the Sub and the Company,  which  calls  for

holders  of  the Debentures shall have the right to convert such Debentures into
such number of shares of Parent  Shares  (as  that term is defined in the Merger

of  Company  Common  Stock  into which such Debentures might have been converted
immediately prior to the Merger;

     NOW, THEREFORE, it is hereby agreed:

1.   Conversion Rights  under  the  Debenture.   Except  as  the  rights  of the
original payee of the Debenture and each registered holder of the  Debenture  to

                         1993 LONG-TERM INCENTIVE PLAN
                              OPTION CANCALLATION



     THIS CANCELLATION/SUBSTITUTION AGREEMENT, made and  entered into as of this
20th day  of  February,  1996,  by  and  between  Tesoro  Petroleum  Corporation
("Tesoro"),  Coastwide  Energy  Services, Inc. ("Coastwide") and the undersigned
("Optionee"), amends the  Nonqualified  Stock  Option  Agreement(s) (the "Option
Agreement") to which the  undersigned  is  a  party  under  the  Coastwide  1993
Long-term Incentive Plan ("Plan"), as follows:

     Notwithstanding  the  terms  of the Option Agreement, the Option granted to
Optionee under the Plan  (the  terms,  definitions,  and provisions of which are
incorporated herein and made a part hereof) is cancelled  as  of  the  Effective
Time.   For  purposes of this agreement, the "Effective Time" means the date and
time on which the Agreement  of  Merger  dated  as  of November 20, 1995, by and
among Coastwide, CNRG Acquisition Corp., and  Tesoro  (the  "Merger  Agreement")
shall be effected, as provided in the Merger Agreement.

     In consideration of the foregoing, the Optionee hereby is granted an option
(the  "Substitute  Option")  upon the same terms and conditions as the Option to
purchase shares of Tesoro Common  Stock,  $.16  2/3 par value per share ("Tesoro
Common Stock"), in an amount and at an exercise price as set  forth  in  Section
2.2(g) of the Merger Agreement, as follows:

     (1)  the  number  of  shares  of  Tesoro  Common Stock to be subject to the
Substitute Option shall be  equal  to  the  product  of  the number of shares of
Coastwide Common Stock  subject  to  the  Option  and  .41,  provided  that  any
fractional  shares  of  Tesoro  Common  Stock resulting from such multiplication
shall be rounded to the nearest whole share, and

     (2) the exercise price per share  of  the Tesoro Common Stock to be subject
to the Substitute Option shall be equal to (i) the exercise price of the  number
of  shares  of Coastwide Common Stock under the Option divided by .41 minus (ii)
$6.2195 (rounded to the nearest  cent),  provided,  that  if such amount is less
than $0, the holder of the Substitute Option shall, upon  exercise,  receive  in
cash the amount by which such amount is less than $0.

     The  Substitute Option shall have the same terms as set forth in the Option
Agreement (including those set forth  in  the  Plan) except that Tesoro shall be
the "Company" for purposes of the Substitute Option.   Following  the  Effective
Time,  all stock options granted to the Optionee under the Agreement or the Plan
are cancelled, and the Optionee shall  have no rights under either the Agreement
or the Plan except as provided herein.

     IN WITNESS WHEREOF, the parties hereto have caused  this  Agreement  to  be
executed the date first written above.

Company, the execution of a Stock  Option  Agreement  in  the  form  hereof  was
authorized by a resolution of the Board of Directors of the Company duly adopted
on October 29, 1993, and incorporated herein by reference; and

     WHEREAS,  the  option  granted  hereby  is intended as a nonqualified stock
option and shall  not  be  treated  as  an  "incentive  stock option" within the
meaning of that term under Section 422A of the Internal Revenue Code of 1986.

     NOW THEREFORE, the Company hereby grants to the Optionee an option pursuant
to the Plan to purchase ____________ shares of  Common  Stock,  $.01  par  value
("Common  Stock"),  of  the  Company at the price of $ __________ per share, and
agrees to cause certificates for any  shares purchased hereunder to be delivered
to the Optionee upon payment  of  the  purchase  price  in  full,  all  subject,
however, to the terms and conditions hereinafter set forth.

     1.   (A)  This option shall become exercisable to the extent of 100% of the
shares  specified  above  on  October 29, 1993.  To the extent exercisable, this
option may be exercised in whole or in part from time to time.

     2.   The option price shall be  payable  in  cash or by check acceptable to
the Company.

     3.   This option shall terminate on the earliest of the following dates:

          (A)  Six months after the Optionee ceases to be an employee or officer
of the Company or a subsidiary, unless he ceases to be such employee or  officer

          (C)  Ten years from the date on which this option was granted.  In the
event  the Optionee shall intentionally commit an act materially inimical to the
interests of the Company  or  Subsidiary,  and  the  Plan Administrator shall so
find, this option shall terminate at the time of such act,  notwithstanding  any
other provision of this Agreement.  Nothing contained in this option shall limit
whatever right the company or a subsidiary might otherwise have to terminate the
employment of the Optionee.

     4.   This option is not transferable by the Optionee otherwise than by will
or the laws of descent and distribution, and is exercisable, during the lifetime
of the Optionee, only by him or by his guardian or legal representative.

     5.   This  option shall not be exercisable if such exercise would involve a
violation of any applicable  federal  or  state  securities law, and the Company
hereby agrees to make reasonable efforts to comply with such securities laws.

     6.   The Board of Directors shall make such adjustments in the option price
and in the number of kind of shares of Common Stock as such Board  in  its  sole
discretion,  exercised  in  good  faith,  may determine is equitably required to
prevent dilution or enlargement  of  the  rights  of the Optionee that otherwise
would result from (a) any stock dividend, stock split,  combination  of  shares,
recapitalization or other change in the capital structure of the Company, or (b)
any  merger,  consolidation,  separation,  reorganization or partial or complete
liquidation, or (c) any other  corporate  transaction  or event having an effect
similar to any of the foregoing.

     7.   If the Company shall be required to withhold any federal, state, local
or foreign tax in connection with  exercise  of  this  option,  it  shall  be  a
condition  to such exercise that the Optionee pay or make provision satisfactory
to the Company for payment of all  such  taxes.  The Optionee may elect that all
or any part of such withholding requirement be satisfied  by  retention  by  the
Company  of  a portion of the shares purchased upon exercise of this option.  If
such election is made, the  shares  so  retained  shall be credited against such
withholding requirement at the fair market value as of the date of exercise.

     8.   The term "Subsidiary" as used in this Agreement means any  corporation
(other than the Company) in an unbroken chain of corporations beginning with the
Company  if  each  of  the  corporations  other than the last corporation in the
unbroken chain owns stock possessing fifty percent or more of the total combined
voting power of all classes of  stock  in  one of the other corporations in such
chain.  For purposes of this Agreement, the continuous employment or service  as
an  officer by the Optionee with the Company or a Subsidiary shall not be deemed
interrupted, and the Optionee  shall  not  be  deemed  to  have  ceased to be an
employee or officer of the Company or any  Subsidiary,  by  reason  or  transfer
among the Company and its Subsidiaries.


     9.   The  option  provided for herein was granted by the Board of Directors
of the Company on October 29, 1993, pursuant to the Plan.

     EXECUTED at Houston, Texas effective October 29, 1993.
