            UNION TEXAS PETROLEUM TO JOIN NEW EXPLORATION VENTURES IN
               BOLIVIA, YEMEN, JORDAN, GREECE AND PAPUA NEW GUINEA

           Houston,  February 12, 1997 -- Union Texas Petroleum  Holdings,  Inc.
(NYSE:  UTH) today  announced  that it is entering into several new  exploration
ventures  in a number of areas  worldwide,  including  Bolivia,  Yemen,  Jordan,
Greece and Papua New  Guinea.  Chairman  and CEO John  Whitmire  and Senior Vice
President  Art Peabody  discussed  the company's  1997  exploration  plans at an
energy conference hosted by PaineWebber today in New York.
           "Our 1997 exploration  activities reflect the major strategic changes
we are making to our exploration  program," said Whitmire.  "We are putting much
greater  emphasis on proven basins with an objective of being a  participant  in
emerging  oil and gas plays in areas that have  proven  hydrocarbon  systems and
significant potential.  We are placing less emphasis on frontier plays which the
company had focused on in the past few years."
           During the past 12 months,  Union Texas has been pursuing a number of
additions to its exploration portfolio:

     *o   The  company  is joining  an oil and gas  venture in Bolivia  where an
          exploration  well is planned for 1997;  Union Texas'  participation in
          the venture is pending final approvals from the Bolivian government.

     *o   In Yemen,  Union  Texas will  participate  in a venture  that plans to
          conduct a seismic program during the first half of 1997 with plans for
          one or two exploration wells in the second half of 1997.
     *o   Union Texas has  entered  into an  agreement  to acquire a 50% working
          interest from a subsidiary of Anadarko  Petroleum  Corp. in an oil and
          gas production  sharing  contract in the Hashemite  Kingdom of Jordan.
          Two  stratigraphic  test  wells are  planned  to be drilled in 1997 to
          evaluate the area's stratigraphic column and confirm the presence of a
          working petroleum system. Union Texas' acquisition is subject to final
          approval by the Natural Resources Authority of Jordan.
     *o   Union Texas also is  participating  in a group led by  Enterprise  Oil
          which the Greek  government has invited to negotiate the conclusion of
          lease   agreements  for  two  blocks  onshore   western   Greece.   If
          negotiations are successfully  concluded,  the venture currently plans
          to  conduct  seismic  studies  in 1997 with  plans to drill in 1998 or
          1999.
     *o   In Papua New Guinea,  Union Texas has signed an agreement in principal
          to enter an additional  exploration block. The block is located in the
          highlands,  where several significant  discoveries  recently have been
          made.
          "We are  very  excited  to  enter  these  new  exploration  ventures,"
Whitmire noted.  "These programs  represent  significant  progress in building a
more  balanced,  long-term  exploration  portfolio.  We are pursuing  additional
high-potential exploration ventures to further expand our opportunities."
          During 1997,  Union Texas plans to participate in 25 to 31 exploration
wells,  including  exploration  programs at its  producing  ventures in the U.K.
North Sea, Indonesia and Pakistan.

           Union Texas  earlier  announced a 1997  capital  spending  program of
approximately  $229 million,  of which $68 million is earmarked for  exploration
activities,  an increase of nearly 90% from $36 million spent in 1996. About $42
million, or 61%, of the $68 million budgeted for exploration programs in 1997 is
allocated for the company's new exploration ventures.
           As part of Union Texas' 1997 exploration program, the company also is
participating in drilling and seismic  activities in Italy's Southern  Apennines
area, onshore and offshore Tunisia,  Alaska's Kenai Peninsula and a new block in
Eastern Pakistan.
           One  of the  largest  independent  producers  located  in  the  U.S.,
Houston-based Union Texas Petroleum  Holdings,  Inc. (NYSE:UTH) explores for and
produces oil and gas overseas  primarily in the U.K.  North Sea,  Indonesia  and
other strategic areas. The company has petrochemical operations in Louisiana.
