Exhibit 10(b)

                  STOCK OPTION AGREEMENT UNDER
                 THE 1991 INCENTIVE PROGRAM OF
      AMOCO CORPORATION AND ITS PARTICIPATING SUBSIDIARIES


Agreement  dated  March  25, 1997 between AMOCO  CORPORATION,  (the
"Corporation") and ENRIQUE J. SOSA (the "Optionee").

  WHEREAS, the Corporation, pursuant to the authority and  approval
of  its  shareholders, adopted, effective April 23, 1991, the  1991
Incentive  Program  of  Amoco  Corporation  and  its  Participating
Subsidiaries  (the  "Program") for the purpose  of  furthering  the
interests  of  the  Corporation and its shareholders  by  providing
additional  incentives  for  key, managerial,  and  other  salaried
employees  who  possess valuable experience and skills  and  giving
such  employees an interest in the Corporation parallel to that  of
the   shareholders  so as to enhance the proprietary  and  personal
interest  of such employees in the Corporation's continued  success
and progress; and

  WHEREAS, the Optionee has been designated as an eligible employee
to whom an option may be granted.

 NOW, THEREFORE, in consideration of the services to be rendered by
the  Optionee and the mutual covenants contained herein, and  other
good  and  valuable  consideration, the  parties  hereto  agree  as
follows:

1.  Program.   All of the terms, conditions and provisions  of  the
Program  are  incorporated  herein by reference.   All  capitalized
terms  used  herein and not otherwise defined shall have  the  same
meanings as set forth in the Program.

2.  Nonqualified  Stock  Option.  The  Corporation  grants  to  the
Optionee,  as  a  matter of separate inducement  and  agreement  in
connection with the Optionee's employment by the Corporation or one
of  its participating subsidiaries, for a period of ten  years from
the  date  of this Agreement, options, not intended as an incentive
or  statutory  stock options, to purchase all or  any  part  of  an
aggregate of  50,000 shares of common stock of the Corporation at a
purchase price of  $90.1875 per share.

3.  Exercise.  Except as otherwise provided in the Program and this
Agreement,  one-half of the total number of options  granted  under
Section  2  shall become exercisable in whole or in part after  the
expiration  of  one  year  from the date of  this  Agreement.   The
remaining options granted under Section 2 shall become  exercisable
in whole or in part after the expiration of two years from the date
of  this Agreement.  No options shall be exercisable if exercise or
delivery  of  shares upon exercise would constitute a violation  of
any federal or state securities or other valid regulation.

4. Employment.

  (a)        Except  as otherwise provided in the Program  or  this
Agreement,  an option granted under Section 2 shall be  exercisable
only  if the Optionee remains in the service of the Corporation  or
of  a participating subsidiary continuously until the expiration of
the applicable period set forth in Section 3, at such rate or rates
of  compensation as shall be determined from time to  time  by  the
Corporation or as provided in any employment agreement between  the
Optionee  and the Corporation or such participating subsidiary,  as
the  case  may be; but except as may be provided in any  employment
agreement between the Optionee and the Corporation, nothing  herein
shall  be  deemed to limit or restrict the right of the Corporation
or  of  such  participating subsidiary to terminate the  Optionee's
employment at any time for any reason.

  (b)    If  the  Optionee's  employment  is  terminated  prior  to
September  30, 2000 for any reason other than Cause, as defined  in
Section  5, or if the Optionee terminates his employment  prior  to
September  30, 2000 for Good Reason, as defined below, the  options
granted  under  Section 2 shall become immediately  exercisable  in
whole or in part for the full grant period set forth in Section  2.
For  purposes of this Agreement, "Good Reason" shall have the  same
meaning as it has in any written Employment Agreement between Amoco
Corporation  and  the  Optionee.  If  no  such  written  Employment
Agreement is in effect, "Good Reason" shall mean termination by the
Optionee  of  his  employment as a consequence of  (i)  a  material
diminution   by   the   Corporation  or  applicable   participating
subsidiary  of Optionee's duties, responsibilities, authorities  or
compensation unless agreed to by the Optionee, or, (ii) failure  of
the Corporation or appropriate participating subsidiary to obtain a
contractual commitment from any successor to employ Optionee in the
same   or  equivalent  capacity  and  at  the  same  or  equivalent
compensation and benefits following a sale or transfer  of  all  or
substantially   all  of  the  Corporation's  assets   or   all   or
substantially all of the assets of Amoco Chemical Company.

  (c)   Notwithstanding anything in this Agreement to the contrary,
an  option granted under Section 2 shall be exercisable only if the
Optionee,  while  employed by the Corporation  or  a  participating
subsidiary, or while all or any portion of an option granted  under
Section  2  remains  in  effect, does not engage  in  any  activity
prejudicial  in  the judgment of the Compensation and  Organization
Committee  or  Human  Resources Committee, as appropriate,  to  the
interests of the Corporation or any of its subsidiaries.

5.  Termination of Employment.  An option granted under  Section  2
shall  expire  ten  years from the date of  this  Agreement  unless
otherwise  terminated at an earlier date pursuant to the provisions
of the Program or this Agreement.  In the event of the death of the
Optionee  during  employment by the Corporation or a  participating
subsidiary   or  the  Optionee  becomes  Totally  Disabled,   after
completing the applicable period of continuous employment  required
by  Section 4(a), an option granted under Section 2 shall expire at
the  earlier of ten years from the date of this Agreement or  three
years  from the date of death.  Termination of employment with  the
Corporation for Cause or voluntary resignation,  prior to September
30,  2000, will result in cancellation of the option granted  under
Section  2 as of the Optionee's termination date.  For purposes  of
this  Agreement,  "Cause"  shall  mean  willful  misconduct,  gross
incompetence  in  the  performance of  the  Optionee's  duties,  or
engaging in any conduct which constitutes a felony.

6.  Notice  of  Exercise.   Subject to the  terms,  conditions  and
provisions  of  this Agreement and the Program, the  Optionee  from
time  to  time  may exercise an option granted under Section  2  to
purchase  all  or  any part of the shares of common  stock  subject
thereto  by  written  notice  to the  Corporation  identifying  the
option  to  be exercised  and  specifying  the  number  of   shares
of   stock   to   be purchased  thereunder, addressed  to:   D.  H.
Clement,  Supervisor-Executive Compensation  Administration,  Amoco
Corporation, 200 East Randolph Drive, Chicago, Illinois  60601,  or
to  any  other person at such address as the Corporation may notify
the  Optionee  in  writing, accompanied  by  full  payment  of  the
purchase  price of said shares in accordance with Section  7.   Any
other notice by the Optionee to the Corporation shall be  similarly
addressed, and any certificates or notices to be delivered  to  the
Optionee  shall  be addressed as set forth beneath  the  Optionee's
signature  hereto  or  as  the Optionee may  otherwise  notify  the
Corporation in writing.

7.  Payment.   Payment by the Optionee upon exercise of  an  option
granted under Section 2 may be made in cash or, in the case  of  an
exercise  with respect to at least 100 shares, in shares of  common
stock  of the Corporation that have been owned by the Optionee  for
at least one year prior to the date of exercise, at the fair market
value per share on the date of exercise.
  
8.  Taxes.   It shall be a condition to delivery by the Corporation
of  certificates for shares under Section 6 that adequate provision
has,  in the judgment of the Corporation, been made for payment  of
any  taxes  which  may be required to be withheld pursuant  to  any
applicable law.

9.  Succession.  This Agreement shall be binding upon and inure  to
the  benefit of the Corporation and its successors and assigns; and
shall  be  binding  upon  and,  to  the  extent  permitted  by  the
provisions  of  the  Program, shall inure to  the  benefit  of  the
Optionee and, in the event of the Optionee's death, to such  person
or  persons  (including the Optionee's Beneficiary) as  shall  have
acquired   the   Optionee's   rights   hereunder   by   beneficiary
designation,  by  will  or  the laws of  descent  and  distribution
applicable  to  the Optionee's estate, but shall not  otherwise  be
transferable or assignable by any of them.

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