                           EMPLOYMENT AGREEMENT


      Union  Oil  Company of California ("Unocal") and  Lawrence  M.  Higby
("Employee") hereby agree that Employee shall provide personal services  to
Unocal  effective July 1, 1994 in accordance with the following  terms  and
conditions:


          1.    Employee  shall  have the title of President,  76  Products
          Company  and shall function as a group Vice-President responsible
          for  refining  and  marketing  activities.   Employee  shall   be
          assigned  such  duties and responsibilities as  established  from
          time  to  time by R. C. Beach, Chief Executive Officer and  Chief
          Operating Officer of Unocal, or his successor or delegate.

          2.    Employee shall be compensated for such services at  a  base
          salary  of  $25,833.38  per calendar month.   Employee  shall  be
          eligible  for  consideration for subsequent salary  increases  in
          accordance with Company practices and standards.

          3.    The  term of this Agreement shall be for a period of  three
          years  beginning  July 1, 1994 and ending June  30,  1997  unless
          Employee  shall  die, become unable or unwilling to  perform  his
          duties  under  this Agreement, resign, or engage  in  misconduct.
          This  Agreement shall terminate automatically on June  30,  1997.
          However,  the obligation of paragraphs 6 and 9 shall survive  the
          termination of this Agreement.

          4.    Employee  shall be eligible for grants under the  Company's
          Long-Term Incentive Plan of 1991 in accordance with the terms  of
          said  plan  and  the practices of the Company.   In  addition  to
          grants  made  at  the normal period, the Chief Executive  Officer
          will recommend to the Compensation Committee of the Board that  a
          pro-rata  grant of stock options and Performance Share Awards  be
          made to Employee during 1994.

          5.    Employee shall be an employee of Unocal. As such,  Employee
          shall  be eligible for and subject to Unocal's benefit plans  and
          employment  policies  that  are generally  applicable  to  Unocal
          employees  in  accordance  with  the  terms  of  said  plans  and
          policies.  Employee shall be subject to all of Unocal's  policies
          and   standards  of  conduct  except  as  otherwise  specifically
          provided herein.


                             - 2 -

          6.   Employee recognizes that any business, economic or technical
          information pertaining to his assignment and/or the technology of
          Unocal Corporation, Union Oil Company of California or of any  of
          its  subsidiaries or affiliates (jointly referred to as  "Union")
          which  is  received or developed by Employee in  connection  with
          Employee's  work  hereunder, or which is otherwise  disclosed  to
          Employee  by  Union  either orally or in  writing,  is  the  sole
          property  of  Union.   Employee agrees to keep  such  information
          confidential and not to use such information except in the course
          of rendering services pursuant to this Agreement.  Employee shall
          not  divulge  such  information to  non-Union  personnel,  unless
          authorized  to  do so by a writing directed to  him  by  Unocal's
          Chief   Executive   Officer  either  while  performing   services
          hereunder  or  thereafter.  The foregoing  obligation  shall  not
          apply  to  information  which Employee can  show  either  (i)  is
          already known to Employee from non-Union sources, or (ii)  is  or
          becomes part of the public domain, other than by the wrongful act
          of Employee.

          7.    This  Agreement is for Employee's unique personal  services
          and may not be assigned or delegated by him unless authorized  in
          writing by the individual designated in Section 1.

          8.   Employee will be eligible for immediate participation in the
          Unocal  Incentive  Compensation Plan.  The "target  award"  under
          said  plan  shall  be  20% of his annual  base  salary  rate  for
          calendar year 1994.  Thereafter, Employee's target award will  be
          determined  in  accordance with the terms of said  plan  and  the
          practices  generally  applicable  to  participants.   The  actual
          payment of any award shall be subject to the general rules of the
          plan,  including  without limitation, achievement  of  individual
          goals,   the  Company's  relative  return  to  shareholders   and
          satisfaction of the financial criteria of the plan.

          9.    In  the event that the Employee resigns, is terminated  for
          misconduct, dies or is unable or unwilling to continue to  render
          the services for which he was retained, no further payments under
          this  Agreement shall be due.  If the Employee is terminated  for
          any  other  reason  during the term of this  Agreement,  Employee
          shall be entitled to his base salary for the greater of one  year
          or  the remaining term of this Agreement.  Employee shall also be
          entitled to a supplemental payment so that to the extent  he  has
          elected  continued Unocal Medical Plan coverage under COBRA,  his
          contribution  rate will be the same as an active Unocal  employee
          with  the same coverage as Employee.  The Employee shall also  be
          entitled to payment


                             - 3 -

          of accrued Incentive Compensation Plan and Performance Share
          Awards to the extent such payment is consistent with the terms of
          said plans.

          10.   If  the Employee remains employed by Unocal or a subsidiary
          after June 30, 1997, this Agreement shall not govern the terms of
          said employment.

          11.  Unocal shall retain the right to change Employee's title and
          assignment from time to time during the term of this Agreement.

          12.   This Agreement constitutes the entire Agreement between the
          parties relating to the subject of this Agreement.  There are  no
          verbal    or   written   agreements,   inducements,   statements,
          representations, promises or understandings between  the  parties
          except as expressly stated in this Agreement.

          13.   Neither Unocal nor Employee shall be deemed to have  waived
          any  right  available  to either party under  this  Agreement  or
          applicable  law  unless such waiver is set  forth  in  a  written
          document  signed  by  Employee  or by  Unocal's  Chief  Executive
          Officer and directed to the other party.

          14.   This  Agreement  may not be modified except  by  a  written
          document  signed by Employee and the Chief Executive  Officer  of
          Unocal.

          15.   The  Agreement shall be interpreted in accordance with  the
          plain meaning of its terms and not strictly for or against any of
          the parties hereto.

          16.   The  validity and interpretation of this Agreement and  the
          legal relationship of the parties to it shall be governed by  the
          laws of the State of California.
