                                  (UNAUDITED)

NOTE 1 -- TRUST ORGANIZATION

     The Mesa Offshore Trust (Trust) was created effective December 1, 1982 when
Mesa Petroleum Co., predecessor to Mesa Limited Partnership, which was
predecessor to MESA Inc., transferred a 99.99% interest in the Mesa Offshore
Royalty Partnership (Partnership) to the Trust. The Partnership was created to
receive and hold a 90% net overriding royalty interest (the Royalty) in ten
producing and nonproducing oil and gas properties located in federal waters
offshore Louisiana and Texas (the Royalty Properties). MESA Inc. owns and
operates its assets through Mesa Operating Co., the operator of the Royalty
Properties. Mesa Operating Co. is also the managing general partner of the
Partnership (the Managing General Partner). As used in this report, the term
Mesa generally refers to the operator of the Royalty Properties, unless
otherwise indicated.

STATUS OF THE TRUST

     Mesa completed the drilling on Matagorda Island block 624 in 1995 and it
drilled five wells from the existing "A" platform on the South Marsh Island
155 block during 1996. Mesa Inc. recovered substantially all remaining costs
related to the South Marsh Island drilling program as of the February 1997
reporting month. In addition, the Trust recovered approximately $.6 million in
administrative expenses paid from the Trust's reserve fund during the period in
which Royalty income was not paid to the Trust, replenishing the Trust's expense
reserve fund balance to $2 million.

     The Trust Indenture provides that the Trust will terminate if the total
amount of cash per year received by the Trust falls below certain levels for
each of three successive years. The recovery of costs associated with the
Matagorda Island 624 and South Marsh Island drilling programs caused the cash
received by the Trust in 1996 to fall below the termination threshold prescribed
in the Indenture. However, based on the overall success of the South Marsh
Island drilling program, payments of Royalty income to the Trust have resumed as
of the April 30, 1997 payable date and the cash it has received in 1997 is above
the termination threshold prescribed in the Trust Indenture.

     Furthermore, the December 31, 1996, reserve report prepared for the
Partnership (see the Trust's 1996 Annual Report on Form 10-K) indicates that 85%
of future net revenues will be received by the Trust during the next two years.
As such, it is possible, depending on market conditions and the success of
future drilling activities, if any, that as early as 1999 the Trust may commence
a period of three successive years in which annual net royalty income would be
below the termination threshold prescribed in the Indenture, resulting in
termination of the Trust pursuant to the terms discussed above.

NOTE 2 -- BASIS OF PRESENTATION

     The accompanying unaudited financial information has been prepared by Texas
Commerce Bank National Association (Trustee) in accordance with the instructions
to Form 10-Q, and the Trustee believes such information includes all the
disclosures necessary to make the information presented not misleading. The
information furnished reflects all adjustments which are, in the opinion of the
Trustee, necessary for a fair presentation of the results for the interim
periods presented. The financial information should be read in conjunction with
the financial statements and notes thereto included in the Trust's 1996 Annual
Report on Form 10-K.

                              MESA OFFSHORE TRUST
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
                                  (UNAUDITED)

     The financial statements of the Trust are prepared on the following basis:

          (a)  Royalty income recorded for a month is the Trust's interest in
     the amount computed and paid by Mesa to the Partnership for such month
     rather than either the value of a portion of the oil and gas produced by
     Mesa for such month or the amount subsequently determined to be 90% of the
     net proceeds for such month;

          (b)  Interest income, interest receivable and distributions payable to
     unitholders include interest to be earned on short-term investments from
     the financial statement date through the next distribution date;

          (c)  Trust general and administrative expenses are recorded in the
     month they accrue;

          (d)  Amortization of the net overriding royalty interest, which is
     calculated on the basis of current royalty income in relation to estimated
     future royalty income, is charged directly to trust corpus since such
     amount does not affect distributable income; and

          (e)  Distributions payable are determined on a monthly basis and are
     payable to unitholders of record as of the last business day of each month.
     However, cash distributions are made quarterly in January, April, July and
     October, and include interest earned from the monthly record dates to the
     date of distribution.

     This basis for reporting royalty income is considered to be the most
meaningful because distributions to the unitholders for a month are based on net
cash receipts for such month. However, it will differ from the basis used for
financial statements prepared in accordance with generally accepted accounting
principles in several respects. Under such principles, royalty income for a
month would be based on net proceeds from production for such month without
regard to when calculated or received and interest income would be calculated
only for the periods covered by the financial statements and would exclude
interest from the period end to the date of distribution.

     The instruments conveying the Royalty provide that Mesa will calculate and
pay the Partnership each month an amount equal to 90% of the net proceeds for
the preceding month. Generally, net proceeds means the excess of the amounts
received by Mesa from sales of oil and gas from the Royalty Properties plus
other cash receipts over operating and capital costs incurred.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
        RESULTS OF OPERATIONS

NOTE REGARDING FORWARD-LOOKING STATEMENTS

     This Form 10-Q 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. All statements other than
statements of historical facts included in this Form 10-Q, including without
limitation the statements under "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and Note 1 to the financial
statements of the Trust regarding the future net revenues of the Trust, are
forward-looking statements. Although MESA Inc. has advised the Trust that it
believes that the expectations reflected in such forward-looking statements are
reasonable, no assurance can be given that such expectations will prove to have
been correct. Important factors that could cause actual results to differ
materially from expectations ("Cautionary Statements") are disclosed in this
Form 10-Q, including, without limitation in conjunction with the forward-looking
statements included in this Form 10-Q. All subsequent written and oral
forward-looking statements attributable to the Trust or persons acting on its
behalf are expressly qualified in their entirety by the Cautionary Statements.

FINANCIAL REVIEW

     During the first quarter of 1997, the Trust had distributable income of
$509,533, representing $.0070 per unit, as compared to no distributable income
in the first quarter of 1996. The resumption of distributions is due to the
recovery as of the February 1997 reporting month of substantially all remaining
costs related to the drilling on South Marsh Island and Matagorda Island
discussed below. The per unit amounts of distributable income for the first
quarter of 1997 and 1996 were earned by month as follows:

                                         1997       1996

                                       =========  =========

     Royalty income increased to $1,111,555 in the first quarter of 1997 as
compared to $36,014 for the first quarter of 1996. The increase in Royalty
income is due to the recovery of drilling costs by Mesa on the South Marsh
Island blocks 155 and 156 and increased prices for natural gas in 1997.

     Production volumes for natural gas increased to 1,635,853 Mcf in the first
quarter of 1997 from 763,371 Mcf in the first quarter of 1996. The average price
received for natural gas was $3.36 per Mcf in the first quarter of 1997 compared
to $2.27 per Mcf in the first quarter of 1996.

     Crude oil, condensate and natural gas liquids production increased to
60,697 barrels in the first quarter of 1997 from 18,809 barrels in the first
quarter of 1996. The average price received for crude oil, condensate and
natural gas liquids was $20.50 per barrel in the first quarter of 1997, compared
to $16.00 per barrel in the first quarter of 1996.

     The increase in natural gas and crude oil, condensate and natural gas
liquids production in the first quarter of 1997 when compared to the first
quarter of 1996 is primarily attributable to new production on South Marsh
Island, partially offset by natural production decline on West Delta.

                                       5

OPERATIONAL REVIEW

     Mesa has advised the Trust that during the first quarter of 1997 its
offshore gas production was marketed under short term contracts at spot market
prices to multiple purchasers, including Penn Union Energy, Energy Source Inc.
and Conoco, and that it expects to continue to market its production under short
term contracts for the foreseeable future. Spot market prices for natural gas in
the first quarter of 1997 were generally higher than spot market prices in the
first quarter of 1996.

     The amount of cash distributed by the Trust is dependent on, among other
things, the sales prices of gas, crude oil, condensate and natural gas liquids
produced from the Royalty Properties and the quantities sold. Substantial
uncertainties exist with regard to future gas and oil prices, which are subject
to fluctuations due to the regional supply and demand for natural gas and oil,
production levels and other activities of OPEC and other oil and gas producers,
weather, industrial growth, conservation measures, competition and other
variables.

     The Brazos A-7 and A-39 blocks experienced a slight increase decrease in
natural gas production in the first quarter of 1997 as compared to the first
quarter of 1996 due to resumed production on the A-3 well on Block A-39 and a
slight decrease in crude oil, condensate and natural gas liquids production
primarily due to natural production decline. The A-3 well on Block A-39 resumed
operation in September 1996 and is producing approximately 3 MMcf of gas per day
as of May 1997. MESA has farmed out a portion of Brazos A-7 to another operator
and will have the option to participate at a 10% working interest in the
completion of an exploratory well being drilled in the second quarter of 1997.
Estimated costs of such participation are $2 million ($.2 million net to the
Trust).

     The South Marsh Island 155 and 156 blocks experienced an increase in
production in the first quarter of 1997 as compared to 1996, primarily due to
new production from the A-20, A-21, A-6 sidetrack, A-22 and A-14 sidetrack wells
which were drilled in the first three quarters of 1996. The initial gross
producing rate of these five wells was approximately 40 MMcf of gas and 1,000
barrels of condensate per day which rate has subsequently declined to
approximately 10 MMcf of gas and 400 barrels of condensate per day as of May
1997. The decrease in production is primarily due to natural production decline.
Mesa has advised the Trust that it may perform a recompletion of the A-6
sidetrack well in the second quarter of 1997.

     The West Delta 61 and 62 blocks experienced a decrease in production in the
first quarter of 1997 as compared to the first quarter of 1996 primarily due to
natural production decline. The Trust is receiving Royalty income from this
property pursuant to a farmout agreement with another operator. The interest in
the farmout wells which is attributable to the Trust consists of a 7.5% net
profits interest.

     Matagorda Island 624 natural gas production increased in the first quarter
of 1997 as compared to the first quarter of 1996, primarily due to improved
performance in the A-1 well. The A-8 development well, which was drilled in the
fourth quarter of 1995, is currently shut in due to mechanical problems. Mesa
has advised the Trust that it is evaluating operations to return the well to
production. Gross producing rate of the block was approximately 5 MMcf of gas
and 100 barrels of condensate per day as of May 1997.

TERMINATION OF THE TRUST

     The terms of the Mesa Offshore Trust Indenture provide that the Trust will
terminate upon the first to occur of the following events: (1) the total amount
of cash received per year by the Trust for each of three successive years
commencing after December 31, 1987 is less than 10 times one-third of the total
amount payable to the Trustee as compensation for such three year period or (2)
a vote by the unitholders in favor of termination. Because the Trust will
terminate in the event the total amount of

                                       6
<PAGE>
cash received per year by the Trust falls below certain levels, it would be
possible for the Trust to terminate even though some of the Royalty Properties
continued to have remaining productive lives. For information regarding the
estimated remaining life of each of the Royalty Properties and the estimated
future net revenues of the Trust based on information provided by Mesa, see the
Trust's 1996 Annual Report on Form 10-K. Upon termination of the Trust, the
Trustee will sell for cash all the assets held in the Trust estate and make a
final distribution to unitholders of any funds remaining after all Trust
liabilities have been satisfied. The discussion set forth above is qualified in
its entirety by reference to the Trust Indenture itself, which is available upon
request from the Trustee.

     Amounts paid to the Trustee as compensation were $123,000, $149,000, and
$177,500 for the years 1996, 1995 and 1994, respectively. Royalty income
received of $1,996,758 as of April 1997 was above the termination threshold
prescribed in the Indenture.

     The terms of the First Amended and Restated Articles of General Partnership
of the Partnership provide that the Partnership shall dissolve upon the
occurrence of any of the following: (a) December 31, 2030; (b) the election of
the Trustee to dissolve the Partnership; (c) the termination of the Trust; (d)
the bankruptcy of the Managing General Partner; or (e) the dissolution of the
Managing General Partner or its election to dissolve the Partnership; provided
that the Managing General Partner shall not elect to dissolve the Partnership so
long as the Trustee remains the only other partner of the Partnership. In the
event of a dissolution of the Partnership and a subsequent winding up and
termination thereof, the assets of the Partnership (i.e., the Royalty interest)
could either (i) be distributed in kind ratably to the Managing General Partner
and the Trustee or (ii) be sold and the proceeds thereof distributed ratably to
the Managing General Partner and the Trustee. In the event of a sale of the
Royalty and a distribution of the cash proceeds to the Trustee, the Trustee
would make a final distribution to unitholders of such cash proceeds plus any
other cash held by the Trust after the payment of or provision for all
liabilities of the Trust, and the Trust would be terminated.

     On April 6, 1997, MESA Inc. signed a definitive agreement with Parker &
Parsley Petroleum Company to merge and create Pioneer Natural Resources Company,
the third largest independent oil and gas exploration and production company in
the United States. The proposed transaction is subject to MESA Inc. and Parker &
Parsley Petroleum Company stockholder approvals. There can be no assurance that
this transaction will be completed or what the final terms or timing thereof
will be. MESA Inc. has advised the Trust that this merger should have no
significant effects on the Trust, although the precise nature of any effects
cannot be predicted or quantified at this time.
