                         MESA REPORTS SECOND QUARTER RESULTS
 
        (IRVING, Texas) -- MESA Inc. ("MESA") today announced financial and
 operating results for the second quarter of 1997 and the six months ended June
 30, 1997.
 Second Quarter 1997
 ===================
        MESA reported a net loss applicable to its common stock of $19.8
 million, or $0.31 per share, during the second quarter of 1997 as compared
 with net income of $4.5 million, or $0.07 per share, during the second quarter
 of 1996.  Second quarter 1997 revenues increased 9 percent to $78.0 million
 from $71.3 million in the second quarter of 1996.  Operating income fell 37
 percent to $13.3 million in the second quarter of 1997 as compared with $21.1
 million in the same period in 1996. 
        Garrett Smith, MESA's acting chief financial officer, stated that the
 net loss comparison is magnified by a one time loss in 1997 and a one time
 gain in 1996.  The second quarter 1997 results include a loss of $5 million
 associated with the sales of MESA's remaining natural gas vehicle businesses. 
 Such loss is reflected in impairment and other income.  The second quarter
 1996 results include a gain of $15.0 million from the revaluation of certain
 reserves and contingencies associated with acquisitions and contract
 settlements which occurred in the mid-to-late 1980's, and a $3.6 million
 charge associated with a reduction of personnel.  MESA's operating results
 were positively impacted by the increase in oil and condensate production as
 a result of the acquisitions to date in 1997.  In addition, the
 recapitalization and restructuring in the summer of 1996 lowered interest
 rates and general and administrative expenses.
 Year-to-Date 1997
 =================
        MESA reported a net loss applicable to its common stock of $13.1
 million, or $0.20 per share, during the first six months of 1997 as compared
 with net income of $5.6 million, or $0.09 per share, during the same period
 in 1996.  Revenues for the first six months of 1997 increased 13 percent to
 $172.1 million from $152.0 million during the first six months of 1996 and
 cash flow from operations increased 12 percent to $87.8 million for the first
 six months of 1997 from $78.6 million for the same period in 1996.  
 Production and Prices
 =====================
 
        MESA's production and average prices are summarized below.

 *Equivalent natural gas production is based on a factor of six Mcf per barrel
 of liquids.
 
        MESA's natural gas production declined in 1997 as a result of natural
 production declines in the Hugoton field and the Gulf Coast and a post-payout
 reduction in MESA's working interest in certain Gulf Coast wells in early
 1997.  MESA's combined natural gas liquids and oil and condensate production
 increased in 1997 as a result of the acquisition of condensate and natural gas
 liquid interests from MAPCO effective January 1, 1997, and the acquisition of
 Greenhill Petroleum Corporation effective April 15, 1997.  
        MESA anticipates that total production for 1997 will increase over 1996
 as a result of the previously mentioned acquisitions and ongoing development
 activities.  A field compression expansion program currently underway in the
 Hugoton field is expected to increase production in the second half of 1997. 
 The recently completed East Cameron 322/323 drilling program is also expected
 to increase Gulf Coast production in the second half of 1997.
        Prices for all of MESA's production fell in the second quarter of 1997
 in comparison to the second quarter of 1996. The lower recognized prices
 reflect the decline in energy commodity prices but were partially offset by
 MESA's hedging activities.
  
       The following table shows the effects of MESA's hedging activities on
 its prices for the periods indicated:

        As a result of physical sales contracts and other hedging arrangements,
 MESA's estimated fixed price profile is as follows:

        In addition to these hedges, MESA entered into an eight-year agreement
 covering 13,000 MMBtus of natural gas per day beginning January 1, 1997. 
 Under this agreement, MESA will receive the NYMEX Henry Hub natural gas price
 plus $0.52 per MMBtu for the first two years and ten percent of the NYMEX West
 Texas Intermediate crude oil price for the remaining six years.
  
Pioneer Natural Resources
 =========================
        On June 27, 1997, the Securities and Exchange Commission declared
 effective the Joint Proxy Statement/Prospectus for the proposed merger of MESA
 Inc. and Parker & Parsley Petroleum Company to form Pioneer Natural Resources
 Company.  Both companies have scheduled special meetings of stockholders on
 August 7, 1997, to consider and vote on the proposed merger.
 Forward Looking Statements
 ==========================
       This announcement includes "forward-looking statements" within the
 meaning of Section 27A of the Securities Act of 1933, as amended, and Section
 21E of the Securities Exchange Act of 1934, as amended  Such forward-looking
 statements include, without limitation, estimates with respect to reserves,
 production levels, cash flows and capital expenditures  Although MESA believes
 that the expectations reflected in such forward-looking statements are
