                      NEPTUNE NATURAL GAS PROCESSING PLANT
                              COMMENCES OPERATIONS


         Houston,  Texas (March 20, 2000) - Enterprise  Products  Partners  L.P.
(NYSE:  EPD)  announced  that the  Neptune  natural  gas  processing  plant  has
commenced  commercial  operations.  Neptune,  with the  capacity  to process 300
million  cubic feet per day  ("MMcfd")  of natural  gas,  is located in St. Mary
Parish,  Louisiana and processes natural gas that is transported on the Nautilus
pipeline system.  Enterprise  operates the plant and has a 66 percent  ownership
interest,  with Marathon Oil Company,  a part of the  USX-Marathon  Group (NYSE:
MRO), a unit of USX Corporation, holding the remaining 34 percent interest.

         Neptune is currently processing  approximately 200 MMcfd of natural gas
originating  primarily from deepwater Gulf of Mexico developments.  The plant is
yielding  16,000  barrels  per day of natural  gas  liquids  ("NGLs")  which are
transported via pipeline to the Promix fractionator,  in which Enterprise owns a
33 1/3 percent interest, for separation into NGL products.

         The Neptune plant is designed to recover in excess of 85 percent of the
ethane and  virtually 100 percent of the propane,  butanes and natural  gasoline
present in the natural gas stream.  At maximum  capacity,  the plant can produce
more than 25,000 barrels per day of NGLs.

         Enterprise   Products  Partners  L.P.,  with  an  enterprise  value  of
approximately  $2  billion,  is one  of the  leading  midstream  energy  service
companies  in North  America,  providing  the complete  services of  processing,
fractionation,  transportation and storage to producers of NGLs and consumers of
NGL products.
