Parts I and II of this Report contain  forward  looking  statements that involve
risks and uncertainties. Accordingly, no assurances can be given that the actual
events and results will not be materially different than the anticipated results
described  in the  forward  looking  statements.  See "Item 1.  Business"  for a
description of various factors that could  materially  affect the ability of the
Partnership to achieve the anticipated  results described in the forward looking
statements.
                                     PART I

ITEM 1.     Business

Parker &  Parsley  86-B,  Ltd.  (the  "Partnership")  is a  limited  partnership
organized  in 1986 under the laws of the State of Texas.  The  managing  general
partner is Parker & Parsley Development L.P. ("PPDLP").  PPDLP's general partner
is Parker & Parsley Petroleum USA, Inc. ("PPUSA").

A Registration  Statement,  as amended,  filed pursuant to the Securities Act of
1933,  registering limited partnership  interests  aggregating  $50,000,000 in a
series  of Texas  limited  partnerships  formed  under the  Parker & Parsley  86
Development  Drilling  Program,  was declared  effective by the  Securities  and
Exchange  Commission  on April 7, 1986.  On October 29,  1986,  the  offering of
limited partnership interests in the Partnership,  the second partnership formed
under such statement,  was closed, with interests aggregating  $17,208,000 being
sold to 1,466 subscribers.

The Partnership  engages primarily in oil and gas development and production and
is not  involved in any  industry  segment  other than oil and gas. See "Item 6.
Selected  Financial  Data" and "Item 8. Financial  Statements and  Supplementary
Data" of this  report for a summary  of the  Partnership's  revenue,  income and
identifiable assets.

The principal  markets during 1996 for the oil produced by the Partnership  were
refineries  and  oil  transmission  companies  that  have  facilities  near  the
Partnership's   oil  producing   properties.   The  principal  markets  for  the
Partnership's   gas  were  companies  that  have  pipelines   located  near  the
Partnership's gas producing  properties.  Of the Partnership's total oil and gas
revenues for 1996,  approximately  43%,  15%, 13% and 12% were  attributable  to
sales made to Genesis  Crude  Oil,  L.P.,  Mobil Oil  Corporation,  Western  Gas
Resources, Inc. and Texaco Trading & Transportation, respectively.

The Partnership's revenues,  profitability,  cash flow and future rate of growth
are highly dependent on the prevailing prices of oil and gas, which are affected
by  numerous  factors  beyond  the  Partnership's  control.  Oil and gas  prices
historically  have been very volatile.  A substantial or extended decline in the
prices of oil or gas could have a material  adverse effect on the  Partnership's
revenues,  profitability and cash flow and could,  under certain  circumstances,
result in a reduction in the  carrying  value of the  Partnership's  oil and gas
properties.

Because of the demand for oil and gas, the Partnership does not believe that the
termination  of the  sales of its  products  to any one  customer  would  have a

                                        2

<PAGE>



material adverse impact on its operations. The loss of a particular customer for
gas  may have  an effect if that particular customer has the  only gas  pipeline
located  in the  areas  of  the  Partnership's  gas  producing  properties.  The
Partnership  believes,  however,  that  the  effect  would be  temporary,  until
alternative arrangements could be made.

Federal and state  regulation of oil and gas operations  generally  includes the
fixing of maximum prices for regulated categories of natural gas, the imposition
of maximum  allowable  production rates, the taxation of income and other items,
and the protection of the  environment.  Although the Partnership  believes that
its business operations do not impair  environmental  quality and that its costs
of complying with any  applicable  environmental  regulations  are not currently
significant,   the  Partnership  cannot  predict  what,  if  any,  effect  these
environmental regulations may have on its current or future operations.

The  Partnership  does not have any  employees  of its own.  PPUSA  employs  659
persons,  many of whom  dedicated  a part of their  time to the  conduct  of the
Partnership's  business  during the period for which this  report is filed.  The
Partnership's  managing  general  partner,  PPDLP  through  PPUSA,  supplies all
management functions.

Numerous  uncertainties  exist in estimating  quantities of proved  reserves and
future net revenues  therefrom.  The  estimates  of proved  reserves and related
future net revenues  set forth in this report are based on various  assumptions,
which may ultimately  prove to be inaccurate.  Therefore,  such estimates should
not be construed as estimates of the current  market value of the  Partnership's
proved reserves.

No material part of the  Partnership's  business is seasonal and the Partnership
conducts no foreign operations.

ITEM 2.     Properties

The  Partnership's  properties  consist  primarily  of  leasehold  interests  in
properties on which oil and gas wells are located.  Such property  interests are
often subject to landowner royalties, overriding royalties and other oil and gas
leasehold interests.

Fractional  working  interests in  developmental  oil and gas prospects  located
primarily  in the  Spraberry  Trend  area of West  Texas  were  acquired  by the
Partnership,  resulting in the Partnership's participation in the drilling of 56
oil and gas wells.  At December 31, 1996, 45 wells were  producing.  Eight wells
and  interests  in two wells,  abandoned  in 1995,  were sold in 1996 and one in
1990. The Partnership received interests in one additional producing oil and gas
well in 1993 due to the Partnership's back-in after payout provision.

For  information  relating  to the  Partnership's  estimated  proved oil and gas
reserves at December 31, 1996, 1995 and 1994, and changes in such quantities for
the years then ended,  see Note 7 of Notes to Financial  Statements  included in
"Item 8. Financial  Statements and Supplementary Data" below. Such reserves have
been estimated by the engineering staff of PPUSA with a review by an independent
petroleum consultant.

ITEM 3.     Legal Proceedings

The Partnership was a party to material  litigation which is described in Note 9
of Notes to Financial  Statements included in "Item 8. Financial  Statements and
Supplementary Data" below.

ITEM 4.     Submission of Matters to a Vote of Security Holders

There were no matters  submitted to a vote of security holders during the fourth
quarter of 1996.

                                     PART II

ITEM 5.   Market for Partnership's Common Equity and Related Stockholder Matters

At March 8, 1997, the Partnership  had 17,208  outstanding  limited  partnership
interests held of record by 1,471  subscribers.  There is no established  public
trading  market  for  the  limited  partnership  interests.  Under  the  limited
partnership  agreement,   PPDLP  has  made  certain  commit  ments  to  purchase
partnership interests at a computed value.

Revenues which, in the sole judgement of the managing general  partner,  are not
required to meet the  Partnership's  obligations are distributed to the partners
at least quarterly in accordance with the limited partnership agreement.  During
the years ended  December 31, 1996 and 1995,  distributions  of  $1,488,332  and
$638,588, respectively, were made to the limited partners.

ITEM 7.     Management's Discussion and Analysis of Financial Condition and
              Results of Operations

Results of operations

1996 compared to 1995

The  Partnership's  1996  oil and gas  revenues  increased  to  $1,700,251  from
$1,481,520 in 1995, an increase of 15%. The increase in revenues resulted from a
25% increase in the average price  received per barrel of oil and a 53% increase
in the average price received per mcf of gas, offset by a 12% decline in barrels
of oil produced and sold and an 18% decline in mcf of gas produced and sold.  In
1996,  54,953 barrels of oil were sold compared to 62,183 in 1995, a decrease of
7,230 barrels.  Of the decrease,  3,861 barrels,  or 6%, was attributable to the
sale of eight oil and gas wells during 1996.  The remaining  decrease of 6%, or,
3,369 barrels,  was due to the decline  characteristics of the Partnership's oil
and gas properties. In 1996, 201,324 mcf of gas were sold compared to 245,744 in
1995,  a  decrease  of 44,420  mcf.  Of the  decrease,  15,539  mcf,  or 6%, was
attributable to the sale of eight oil and gas wells.  The remaining  decrease of
28,881 mcf, or 12%, was due to the decline  characteristics of the Partnership's
oil and gas properties.  Because of these characteristics,  management expects a
certain  amount of decline in  production  to continue  in the future  until the
Partnership's economically recoverable reserves are fully depleted.

The average price received per barrel of oil increased $4.35 from $17.22 in 1995
to $21.57 in 1996,  while the average  price  received per mcf of gas  increased
from $1.67 in 1995 to $2.56 in 1996.  The market  price for oil and gas has been
extremely  volatile in the past decade,  and management expects a certain amount
of  volatility  to continue  in the  foreseeable  future.  The  Partnership  may
therefore  sell its future oil and gas  production  at average  prices  lower or
higher than that received in 1996.

Salvage income of $12,859  received  during 1996 consisted of equipment  credits
received on two fully  depleted  wells,  as compared to salvage income of $3,991
received during 1995 which consisted of equipment  credits received on one fully
depleted abandoned well.

During 1996, the Partnership  recognized a gain on sale of assets of $55,709. Of
this amount,  $51,377, from the sale of six oil and gas wells and four saltwater
disposal wells to Costilla Energy, L.L.C., was attributable to proceeds received
of $209,248 less the write-off of remaining  capitalized well costs of $157,871.
An additional  unrelated  sale of four fully depleted oil and gas wells resulted
in proceeds received of $4,332.

On April 29, 1996,  Southmark,  PPDLP and the  Partnership  entered into a final
$7.4 million  settlement  agreement with Jack N. Price resolving all outstanding
litigation  between the parties.  As a result,  all of the pending  lawsuits and
judgments have been dismissed,  the supersedeas  bond released,  and the Reserve
released as collateral.  On June 28, 1996, a final  distribution was made to the
working interest owners,  including $560,099,  or $32.55 per limited partnership
interest, to the Partnership and its partners.  See Note 9 of Notes to Financial
Statements included in "Item 8. Financial Statements and Supplementary Data".

Total  costs  and  expenses  decreased  in 1996 to  $1,122,085  as  compared  to
$1,528,663  in 1995,  a decrease of  $406,578,  or 27%.  The decrease was due to
declines  in  production  costs,  depletion  and the  impairment  of oil and gas
properties, offset by an increase in general and administrative expenses ("G&A")
and abandoned property costs.

Production  costs were  $730,032 in 1996 and  $754,893 in 1995,  resulting  in a
$24,861  decrease,  or 3%. This  decrease was due to declines in well repair and
maintenance  costs,  offset by an increase in  workover  expense  incurred in an
effort to stimulate well production.

G&A's  components are  independent  accounting and  engineering  fees,  computer
services,  postage and managing  general partner  personnel  costs.  During this
period,  G&A  increased,  in  aggregate,  15% from $44,446 in 1995 to $51,008 in
1996. The  Partnership  paid the managing  general  partner  $43,546 in 1996 and
$36,568 in 1995 for G&A incurred on behalf of the Partnership. G&A is allocated,
in part, to the  Partnership by the managing  general  partner.  The Partnership
agreement  limits  allocated  G&A to 3% of  gross  oil  and gas  revenues.  Such
allocated expenses are determined by the managing general partner based upon its
judgement of the level of activity of the  Partnership  relative to the managing
general  partner's  activities  and other  entities  it  manages.  The method of
allocation  has varied in  certain  years and may do so again  depending  on the
activities of the managed entities.

The  Partnership  adopted  Statement of Financial  Accounting  Standards No. 121
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
be Disposed Of" ("SFAS 121")  effective as of October 1, 1995 (see Notes 2 and 3
of Notes to Financial  Statements included in "Item 8. Financial  Statements and
Supplementary Data"). As a result of the review and evaluation of its long-lived
assets for impairment, the Partnership recognized non-cash charges of $4,960 and
$244,024  related  to  its  oil  and  gas  properties   during  1996  and  1995,
respectively.

Depletion was $327,745 in 1996 compared to $483,642 in 1995. This  represented a
decrease of $155,897,  or 32%. This decrease was primarily  attributable  to the
following  factors:  (i) a reduction in the  Partnership's  net depletable basis
from  charges  taken in  accordance  with  SFAS  121,  (ii) a  reduction  in oil
production  in 1996 from  1995 of 7,230  barrels,  partially  due to the sale of
properties  during the same period in 1996, and (iii) an increase in oil and gas
reserves during 1996 as a result of higher commodity prices.

Abandoned  property  costs of  $8,340  were  incurred  on one well  during  1996
compared to $1,658 incurred in 1995 to plug and abandon two wells.

1995 compared to 1994

The  Partnership's  1995  oil and gas  revenues  decreased  to  $1,481,520  from
$1,584,722  in 1994, a decrease of 7%. The decrease in revenues  resulted from a
12% decline in barrels of oil produced and sold and an 11% decline in mcf of gas
produced and sold,  offset by an 8% increase in the average  price  received per
barrel of oil. In 1995,  62,183  barrels of oil were sold  compared to 70,542 in
1994,  a  decrease  of 8,359  barrels.  In 1995,  245,744  mcf of gas were  sold

                                        7

<PAGE>



compared  to 274,904 in 1994,  a decrease  of 29,160  mcf.  The  decreases  were
primarily due to the decline  characteristics  of the  Partnership's oil and gas
properties.

The average price received per barrel of oil increased $1.26 from $15.96 in 1994
to $17.22 in 1995,  while the average price  received per mcf of gas remained at
$1.67 in 1994 and 1995.

Salvage income of $3,991  received  during 1995  consisted of equipment  credits
received on one fully depleted abandoned well. Expenses incurred in 1995 to plug
and abandon two wells totaled $1,658.  There was no abandonment  activity during
1994.

Total  costs  and  expenses  decreased  in 1995 to  $1,528,663  as  compared  to
$1,562,438  in 1994,  a decrease  of  $33,775,  or 2%. The  decrease  was due to
declines  in  production  costs,  G&A and  depletion,  offset by an  increase in
abandoned property costs and the impairment of oil and gas properties.

Production  costs were  $754,893 in 1995 and  $803,469 in 1994,  resulting  in a
$48,576  decrease,  or 6%. This  decrease was due to declines in well repair and
maintenance costs and production and ad valorem taxes.

G&A's  components are  independent  accounting and  engineering  fees,  computer
services,  postage and managing  general partner  personnel  costs.  During this
period, G&A decreased, in aggregate, 7% from $47,542 in 1994 to $44,446 in 1995.
The Partnership paid the managing general partner $36,568 in 1995 and $37,030 in
1994 for G&A incurred on behalf of the Partnership.

The  Partnership  adopted SFAS 121  effective as of October 1, 1995 (see Notes 2
and 3 of Notes to Financial Statements included in "Item 8. Financial Statements
and  Supplementary  Data").  As a result of the  review  and  evaluation  of its
long-lived assets for impairment,  the Partnership  recognized a non-cash charge
of $244,024  related to its oil and gas properties  during the fourth quarter of
1995.

Depletion was $483,642 in 1995 compared to $711,427 in 1994. This  represented a
decrease of $227,785,  or 32%. Oil  production  decreased  8,359 barrels in 1995
from 1994,  while oil reserves of barrels were revised upward by 15,292 barrels,
or 2%.

Impact of inflation and changing prices on sales and net income

Inflation  impacts  the fixed  overhead  rate  charges  of the  lease  operating
expenses for the  Partnership.  During 1994,  the annual  change in the index of
average weekly earnings of crude petroleum and gas production  workers issued by
the U.S. Department of Labor, Bureau of Labor Statistics  increased by 4.8%. The
1995  annual  change  in  average  weekly  earnings  increased  by 4.4%  and was
implemented  April 1, 1995. The 1996 index  (effective  April 1, 1996) increased
4.1%. The impact of inflation for other lease operating expenses is small due to
the current economic condition of the oil industry.

The oil and gas industry  experienced  volatility during the past decade because
of the fluctuation of the supply of most fossil fuels relative to the demand for
such  products  and other  uncertainties  in the world  energy  markets  causing
significant  fluctuations  in oil and gas  prices.  During  1996,  the price per
barrel for oil production similar to the Partnership's ranged from approximately
$18.00 to $25.00. For February 1997, the average price for the Partnership's oil
was approximately $22.00.

Prices for natural gas are subject to ordinary seasonal  fluctuations,  and this
volatility of natural gas prices may result in production  being  curtailed and,
in some cases, wells being completely shut-in.

Liquidity and capital resources

Net Cash Provided by Operating Activities

Net cash provided by operating  activities  increased  $716,736  during the year
ended December 31, 1996 from the year ended December 31, 1995. This increase was
primarily  due to the receipt of proceeds  from the  litigation  settlement  (as
discussed  in Note 9 of  Notes  to  Financial  Statements  included  in "Item 8.
Financial  Statements  and  Supplementary  Data") and an increase in oil and gas
sales receipts.

Net Cash Provided by (Used in) Investing Activities

The Partnership's  investing activities during 1996 and 1995 were related to the
disposal or addition of oil and gas equipment on active properties.

Proceeds from salvage income of $12,859 and $3,991 were received during 1996 and
1995, respectively, from the sale of oil and gas equipment on one fully depleted
well.

Proceeds of $213,581 were received  during 1996 from the sale of ten oil and gas
wells.

Net Cash Used in Financing Activities

Cash was sufficient in 1996 for  distributions  to the partners of $1,503,365 of
which  $1,488,332  was  distributed  to the limited  partners and $15,033 to the
managing general partner.  In 1995, cash was sufficient for distributions to the
partners of $645,040 of which $638,588 was  distributed to the limited  partners
and $6,452 to the managing general partner.

Cash  distributions to the partners of $1,503,365 for 1996 included  $560,099 to
the limited partners and $5,657 to the managing  general partner  resulting from
proceeds  received in the litigation  settlement as discussed in Note 9 of Notes
to  Financial   Statements  included  in  "Item  8.  Financial   Statements  and
Supplementary Data".

                                       9

It is expected that future net cash  provided by  operations  will be sufficient
for any capital  expenditures and any distributions.  As the production from the
properties declines, distributions are also expected to decrease.

The Partners
Parker & Parsley 86-B, Ltd.
  (A Texas Limited Partnership):

We have  audited the  financial  statements  of Parker & Parsley  86-B,  Ltd. as
listed in the accompa nying index under Item 14(a).  These financial  statements
are the responsibility of the Partnership's management. Our responsibility is to
express an opinion on these financial statements based on our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all material respects,  the financial position of Parker & Parsley 86-B, Ltd. as
of December 31, 1996 and 1995,  and the results of its  operations  and its cash
flows for each of the years in the three-year period ended December 31, 1996, in
conformity with generally accepted accounting principles.

As  discussed  in Notes 2 and 3 to the  financial  statements,  the  Partnership
adopted the provisions of the Financial  Accounting  Standards Board's Statement
of Financial  Accounting  Standards No. 121,  "Accounting  for the Impairment of

                          (A Texas Limited Partnership)

                          NOTES TO FINANCIAL STATEMENTS
                        December 31, 1996, 1995 and 1994

Note 1.     Organization and nature of operations

       Parker & Parsley 86-B, Ltd.  (the "Partnership") is a limited partnership
organized in 1986 under the laws of the State of Texas.

       The  Partnership  engages  primarily  in  oil  and  gas  development  and
production  in Texas and is not involved in any industry  segment other than oil
and gas.

Note 2.     Summary of significant accounting policies

       A summary of the significant  accounting policies consistently applied in
the preparation of the accompanying financial statements follows:

       Impairment of long-lived assets  - Commencing in 1995, in accordance with
Statement  of  Financial  Accounting  Standards  No.  121,  "Accounting  for the
Impairment of  Long-Lived  Assets and for  Long-Lived  Assets to be Disposed Of"
("SFAS 121"), the Partnership  reviews its long-lived assets to be held and used
on an individual property basis,  including oil and gas properties accounted for
under  the  successful   efforts  method  of  accounting,   whenever  events  or
circumstances  indicate  that the  carrying  value of  those  assets  may not be
recoverable.  An impairment  loss is indicated if the sum of the expected future
cash flows is less than the carrying amount of the assets. In this circumstance,
the  Partnership  recognizes  an  impairment  loss for the  amount  by which the
carrying amount of the asset exceeds the fair value of the asset.

       The Partnership  accounts for long-lived  assets to be disposed of at the
lower of their carrying  amount or fair value less costs to sell once management
has committed to a plan to dispose of the assets.

       Prior to the  adoption  of SFAS 121 in the fourth  quarter  of 1995,  the
Partnership's aggregate oil and gas properties were stated at cost not in excess
of total  estimated  future net revenues and the estimated fair value of oil and
gas assets not being depleted.

       Oil and gas properties - The Partnership  utilizes the successful efforts
method of accounting for its oil and gas  properties  and equipment.  Under this
method, all costs associated with productive wells and nonproductive development
wells are  capitalized  while  nonproductive  exploration  costs  are  expensed.
Capitalized   costs  relating  to  proved  properties  are  depleted  using  the
unit-of-production  method on a  property-by-property  basis based on proved oil
(dominant  mineral)  reserves as determined by the engineering staff of Parker &
Parsley  Petroleum  USA, Inc.  ("PPUSA"),  the sole general  partner of Parker &
Parsley Development L.P. ("PPDLP"),  the Partnership's managing general partner,
and reviewed by  independent  petroleum  consultants.  The  carrying  amounts of
properties  sold  or  otherwise  disposed  of and  the  related  allowances  for
depletion are  eliminated  from the accounts and any gain or loss is included in
operations.
                                       22

<PAGE>




       Use of estimates in the preparation of financial statements - Preparation
of the accompanying  financial  statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect  the  reported  amounts  of assets  and  liabilities  and  disclosure  of
contingent  assets and  liabilities at the date of the financial  statements and
the  reporting  amounts of revenues and expenses  during the  reporting  period.
Actual results could differ from those estimates.

       Net  income  (loss)  per  limited  partnership  interest - The net income
(loss) per limited  partnership  interest is  calculated  by using the number of
outstanding limited partnership interests.

       Income taxes - A Federal  income tax  provision  has not been included in
the  financial  statements as the income of the  Partnership  is included in the
individual Federal income tax returns of the respective partners.

       Statements of cash flows - For purposes of reporting cash flows, cash and
cash equivalents include depository accounts held by banks.

       General and administrative expenses - General and administrative expenses
are allocated in part to the Partnership by the managing  general partner or its
affiliates.  Such  allocated  expenses are  determined  by the managing  general
partner  based upon its  judgement  of the level of activity of the  Partnership
relative to the managing  general  partner's  activities  and other  entities it
manages.  The method of  allocation  has  varied in certain  years and may do so
again depending on the activities of the managed entities.

       Environmental  - The Partnership is subject to extensive  federal,  state
and local  environmental laws and regulations.  These laws, which are constantly
changing,  regulate  the  discharge of materials  into the  environment  and may
require the  Partnership to remove or mitigate the environ mental effects of the
disposal  or release of  petroleum  or  chemical  substances  at various  sites.
Environmental expenditures are expensed or capitalized depending on their future
economic benefit.  Expenditures  that relate to an existing  condition caused by
past  operations  and  that  have no  future  economic  benefits  are  expensed.
Liabilities  for   expenditures  of  a  noncapital   nature  are  recorded  when
environmental  assessment and/or  remediation is probable,  and the costs can be
reasonably estimated.

Note 3.     Impairment of long-lived assets

      The  Partnership  adopted SFAS 121 effective  October 1, 1995. In order to
determine  whether an impairment  had occurred,  the  Partnership  estimated the
expected  future  cash flows of its oil and gas  properties  and  compared  such
future  cash  flows to the  carrying  amount  of the oil and gas  properties  to
determine  if the  carrying  amount  was  recoverable.  For  those  oil  and gas
properties  for which the carrying  amount  exceeded the  estimated  future cash
flows,  an  impairment  was  determined  to exist;  therefore,  the  Partnership
adjusted the carrying amount of those oil and gas properties to their fair value
as determined by discounting their expected future cash flows at a discount rate
commensurate with the risks involved in the industry.  As a result of the review
and  evaluation  of  its  long-lived  assets  for  impairment,  the  Partnership

                                       23

recognized  non-cash  charges of $4,960 in 1996 and  $244,024 in 1995 related to
its oil and gas properties.

Note 4.     Income taxes

      The  financial  statement  basis  of  the  Partnership's  net  assets  and
liabilities was $2,244,196 greater than the tax basis at December 31, 1996.

Note 7.     Oil and gas information (unaudited)

       The following table presents  information  relating to the  Partnership's
estimated  proved oil and gas reserves at December  31, 1996,  1995 and 1994 and
changes in such quantities during the years then ended. All of the Partnership's
reserves  are proved and located  within the United  States.  The  Partnership's
reserves are based on an evaluation  prepared by the engineering  staff of PPUSA
and reviewed by an independent petroleum consultant,  using criteria established
by  the  Securities  and  Exchange  Commission.  Reserve  value  information  is
available  to  limited  partners  pursuant  to the  Partnership  agreement  and,
therefore, is not presented.

       The estimated  present  value of future net revenues of proved  reserves,
calculated  using December 31, 1996 prices of $24.80 per barrel of oil and $3.99
per mcf of gas, discounted at 10% was approximately  $8,148,000 and undiscounted
was $16,994,000 at December 31, 1996.

       The  Partnership   emphasizes  that  reserve   estimates  are  inherently
imprecise  and,  accordingly,  the  estimates  are  expected to change as future
information becomes available.

Note 8.     Major customers

       The following table reflects the major customers of the Partnership's oil
and gas sales (a major  customer is defined as a customer whose sales exceed 10%
of total sales) during the years ended December 31:

       The  above  customers  represent  72% of  total  accounts  receivable  at
December 31, 1996.

       PPDLP is party to a  long-term  agreement  pursuant  to which  PPDLP  and
affiliates are to sell to Basis Petroleum,  Inc. (formerly Phibro Energy,  Inc.)
substantially  all crude oil (including  condensate)  which any of such entities
have the right to market from time to time.  On September  23,  1996,  PPDLP and
Basis Petroleum,  Inc. entered into an agreement that supersedes the prior crude
oil purchase  agreement  between the parties and  provides  for  adjusted  terms
effective  December 1, 1995. On November 25, 1996, the Company  consented to the
assignment of the agreement to Genesis  Crude Oil, L.P.  ("Genesis"),  a limited
partnership formed by Basis Petroleum, Inc. and Howell Corporation. The price to
be paid by Genesis for oil purchased under the agreement  ("Genesis  Agreement")
is to be  competitive  with prices paid by other  substantial  purchasers in the
same areas who are significant  competitors of Genesis. The price to be paid for
oil purchased under the Genesis Agreement  includes a market-related  bonus that
may vary from month to month  based  upon spot oil  prices at various  commodity
trade points. The term of the Genesis Agreement is through June 30, 1998, and it
may continue  thereafter  subject to  termination  rights  afforded  each party.
Salomon,  Inc., the parent company of Basis  Petroleum,  Inc. and a subordinated
limited partner in Genesis,  secures the payment  obligations  under the Genesis
Agreement with a $25 million payment guarantee.  Accounts receivable-oil and gas
sales included $99,377 due from Genesis at December 31, 1996.

Note 9.     Contingencies

       On May 25, 1993, a final settlement agreement was negotiated, drafted and
finally  executed,  ending litigation which had begun on September 5, 1989, when
the Partnership filed suit along with other parties against Dresser  Industries,
Inc.;  Titan  Services,  Inc.;  BJ-Titan  Services  Company;  BJ-Hughes  Holding
Company;  Hughes Tool Company;  Baker Hughes Production  Tools,  Inc.; and Baker
Hughes  Incorporated  alleging that the defendants had  intentionally  failed to
provide the materials and services  ordered and paid for by the  Partnership and
other parties in connection with the fracturing and acidizing of 523 wells,  and
then  fraudulently  concealed  the  shorting  practice  from  Parker  &  Parsley
Development L.P. ("PPDLP").  The May 25, 1993 settlement  agreement called for a
payment  of  $115  million  in  cash  by  the  defendants,  and  Southmark,  the
Partnership,  and the other  plaintiffs  indemnified the defendants  against the
claims of Jack N.  Price.  The  managing  general  partner  received  the funds,
deducted incurred legal expenses,  calculated  accrued interest,  determined the
general  partner's  portion of the funds and  calculated  any  inter-partnership
allocations.

       On May 3, 1993,  Jack N. Price,  the  attorney  who  represented  Gary G.
"Zeke"  Lancaster  in the Federal  Court  lawsuit,  filed suit in State Court in
Beaumont  against all of the plaintiff  partnerships,  including the Partnership
and others, alleging his entitlement to 12% of the settlement proceeds.  Price's
lawsuit  claim for  approximately  $13.8  million was  predicated on a purported
contract  entered  into with  Southmark  Corporation  in August 1988 in which he
allegedly bound the Partnership and the other defendants,  as well as Southmark.
Although PPDLP believed the lawsuit to be without merit and vigorously  defended
it,  PPDLP  held in reserve  approximately  12.5% of the total  settlement  (the
"Reserve") pending final resolution of the litigation.

                                       27

<PAGE>



       A distribution  of $91,000,000 was made to the working  interest  owners,
including the Partnership, on July 30, 1993. The limited partners received their
distribution  of $5,500,648,  or $319.66 per limited  partnership  interest,  in
September 1993. The allocation of the lawsuit

settlement amount was based on the original verdict entered on October 26, 1990.
The  allocation  to the  working  interest  owners in each well  (including  the
Partnership)  was  based on a ratio of the  relative  amount of  damages  due to
overcharges  for services and  materials  ("Materials")  and damages for loss of
past and future  production  ("Production"),  each as determined in that initial
judgment.  Within the Partnership,  damages for Materials were allocated between
the partners based on their original sharing  percentages for costs of acquiring
and/or  drilling  of  wells.  Similarly,  damages  related  to  Production  were
allocated to the partners in the Partnership  based on their respective share of
revenues from the subject wells.

       As a condition of the purchase by Parker & Parsley  Petroleum  Company of
Parker & Parsley  Development  Company ("PPDC"),  which was merged into PPDLP on
January 1, 1995,  from its former  parent in May 1989,  PPDC's  interest  in the
lawsuit  and   subsequent   settlement   was  retained  by  the  former  parent.
Consequently,  all of PPDC's share of the  settlement  related to its separately
held  interests  in the wells and its  partnership  interests  in the  sponsored
partnerships  (except that portion allocable to interests acquired by PPDC after
May 1989) was paid to the former parent.

       On  September  20,  1995,  the  Beaumont  trial  judge  entered a summary
judgment against  Southmark for the $13,790,000  contingent fee sought by Price,
together  with  prejudgment  interest,  and also  awarded  Price  an  additional
$5,498,525 in attorneys'  fees. On January 22, 1996,  the trial judge entered an
interlocutory  summary judgment against Dresser  Industries and Baker Hughes for
an  amount  to be  determined.  Pursuant  to their  indemnity  obligations,  the
Partnership, Southmark, PPDLP and other original plaintiffs vigorously protected
the rights of both Dresser and Baker Hughes.  Southmark  vigorously  pursued its
appeal of the  judgment,  and posted a  supersedeas  bond  using the  Reserve as
collateral. On April 29, 1996, all of the parties, including the Partnership and
Southmark,  entered  into a $7.4 million  settlement  with Price which fully and
finally  resolved  all of the  litigation  and  disputes  between  the  parties,
including the Partnership's indemnity obligations to Dresser and Baker Hughes.

       Pursuant to the  settlement  agreement,  all of the pending  lawsuits and
judgments have been dismissed,  the supersedeas  bond released,  and the Reserve
released as collateral.  On June 28, 1996, a final  distribution was made to the
working interest owners,  including $560,099,  or $32.55 per limited partnership
interest to the Partnership and its partners.

Note 10.     Organization and operations

       The Partnership was organized  October 29, 1986 as a limited  partnership
under the Texas Uniform Limited Partnership Act for the purpose of acquiring and
developing oil and gas properties.  The following is a brief summary of the more
significant provisions of the limited partnership agreement:

                                       28

<PAGE>



       Managing   general  partner  -  The  managing   general  partner  of  the
       Partnership  is  PPDLP.  PPDLP has the power  and  authority  to  manage,
       control and administer  all Program and  Partnership  affairs.  Under the
       limited  partnership  agreement,  the managing general partner pays 1% of
       the  Partnership's  acquisition,  drilling and completion costs and 1% of
       its operating and general and administrative  expenses.  In return, it is
       allocated 1% of the Partnership's revenues.

       Limited  partner  liability  - The  maximum  amount of  liability  of any
       limited partner is the total contributions of such partner plus his share
       of any undistributed profits.

       Initial  capital  contributions  -  The  limited  partners  entered  into
       subscription   agreements   for  aggregate   capital   contributions   of
       $17,208,000.  PPDLP is  required  to  contribute  amounts  equal to 1% of
       initial   Partnership  capital  less  commission  and  offering  expenses
       allocated to the limited partners and to contribute  amounts necessary to
       pay costs and expenses allocated to it under the Partnership agreement to
       the extent its share of revenues does not cover such costs.

Note 11.     Disposition of Assets

       A gain of  $51,377  from  the  sale of six oil  and gas  wells  and  four
saltwater disposal wells to Costilla Energy,  L.L.C. was recognized during 1996,
resulting  from  proceeds  received of $209,248  less the write-off of remaining
capitalized well costs of $157,871.  An additional  unrelated sale of four fully
depleted  oil and gas wells  resulted  in  proceeds  and an  additional  gain of
$4,332.
