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 90-B, L.P. (the "Partnership") is a limited partnership
organized in 1990 under the laws of the State of Delaware. 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 $70,000,000 in a
series of Delaware limited partnerships formed under the Parker & Parsley 89-90
Development Drilling Program, was declared effective by the Securities and
Exchange Commission on August 1, 1989. On October 5, 1990, the offering of
limited partnership interests in the Partnership, the fourth partnership formed
under such statement, was closed, with interests aggregating $32,264,000 being
sold to 2,248 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 operating information
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 63% and 13% were attributable to sales made to
Genesis Crude Oil, L.P. and Western Gas Resources, Inc., 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
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 104
oil and gas wells. One well was plugged and abandoned in 1995 due to
uneconomical operations. At December 31, 1996, the Partnership had 103 producing
oil and gas wells.

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 is not aware of any material legal proceedings (other than
routine litigation in the ordinary course of the Partnership's business) to
which it is a party or to which its properties are subject.

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 32,264 outstanding limited partnership
interests held of record by 2,263 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, $1,814,872 and $1,576,695,
respectively, of such revenue-related distributions 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 $3,748,608 from
$3,147,004 in 1995, a 19% increase. The increase in revenues resulted from a 27%
increase in the average price received per barrel of oil and a 46% increase in
the average price received per mcf of gas, offset by a 9% decline in barrels of
oil produced and sold and a 10% decline in mcf of gas produced and sold. In
1996, 130,683 barrels of oil were sold compared to 143,136 in 1995, a decrease
of 12,453 barrels. In 1996, 353,616 mcf of gas were sold compared to 394,179 in
1995, a decrease of 40,563 mcf. The decrease in production volumes was due to
the decline characteristics of the Partnership's oil and gas properties.
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 $4.59 from $17.16 in 1995
to $21.75 in 1996, while the average price received per mcf of gas increased
from $1.75 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 totaling $8,529 was received during 1996 attributable to credits
received from the disposal of oil and gas equipment on one well that was plugged
and abandoned in a prior year and to credits received from the disposal of oil
and gas equipment on five fully depleted wells.

A gain on sale of property of $2,326 was recognized during 1995. This gain was
the result of proceeds received from the sale of mineral rights on an
undeveloped property.

Total costs and expenses decreased in 1996 to $2,299,612 as compared to
$2,674,896 in 1995, a decrease of $375,284, or 14%. The decrease was due to
declines in production costs, depletion, abandoned property costs, the
impairment of oil and gas properties and amortization of organization costs,
offset by increases in general and administrative expenses ("G&A") and loss on
abandoned property.

Production costs were $1,420,416 in 1996 and $1,424,543 in 1995, resulting in a
$4,127 decrease. The decrease was due to less well repair and maintenance costs,
offset by an increase in workover costs incurred in an effort to stimulate well
production.

1996. The Partnership paid the managing general partner $101,293 in 1996 and
$93,693 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. 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 $61,080
and $312,969 related to its oil and gas properties during 1996 and 1995,
respectively.

Depletion was $703,207 in 1996 compared to $819,927 in 1995. This represented a
decrease of $116,720, or 14%. 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 of 12,453 barrels in 1996 from 1995, and (iii) an increase in oil and
gas reserves during 1996 as a result of higher commodity prices.

A loss on abandoned property of $2,017 was recognized during 1996. This loss
resulted from the write-off of remaining capitalized well costs on the
abandonment of one saltwater disposal well. A gain on abandoned property of
$8,964 was recognized during 1995. This gain was the result of proceeds received
from equipment salvage on one fully depleted abandoned property. Abandoned
property costs of $6,974 were incurred on one well during 1995.

1995 compared to 1994

The Partnership's 1995 oil and gas revenues decreased to $3,147,004 from
$3,434,740 in 1994, an 8% decrease. The decline in revenues resulted from a 13%
decrease in barrels of oil produced and sold, a 15% decrease in mcf of gas
produced and sold and a 2% decrease in the average price received per mcf of
gas, offset by an 8% increase in the average price received per barrel of oil.
In 1995, 143,136 barrels of oil were sold compared to 163,591 in 1994, a
decrease of 20,455 barrels. Of the decrease, 2,340 barrels, or 2%, was
attributable to the fact that on April 1, 1994, the Partnership's revenue and
operating expense allocation pursuant to the Program (as defined in Item 11)
agreement reverted to 80.808081% from 85.858586%. The additional decrease of
11%, or 18,115 barrels, was due to the decline characteristics of the
Partnership's oil and gas properties. In 1995, 394,179 mcf of gas were sold
compared to 466,258 in 1994, a decrease of 72,079 mcf. Of the decrease, 6,294
mcf, or 1%, was attributable to the fact that the revenue and operating expense
allocation reverted to 80.808081% from 85.858586%, as discussed previously. The
additional decrease of 14%, or 65,785 mcf, was due to the decline
characteristics of the Partnership's oil and gas properties.

The average price received per barrel of oil increased $1.28 from $15.88 in 1994
to $17.16 in 1995, while the average price received per mcf of gas decreased
from $1.79 in 1994 to $1.75 in 1995.

A gain on sale of property of $2,326 was recognized during 1995. This gain was
the result of proceeds received from the sale of mineral rights on an
undeveloped property.

Total costs and expenses decreased in 1995 to $2,674,896 as compared to
$2,829,127 in 1994, a decrease of $154,231, or 5%. The decrease was due to
declines in production costs, depletion and amortization of organization costs,
offset by increases in G&A, gain on abandoned property, abandoned property costs
and the impairment of oil and gas properties.

Production costs were $1,424,543 in 1995 and $1,618,843 in 1994, resulting in a
$194,300 decrease, or 12%. Of the decrease, 2% was attributable to the fact that
on April 1, 1994, the Partnership's revenue and operating expense allocation
pursuant to the Program agreement reverted to 80.808081% from 85.858586%. The
additional decrease of 10% was due to less well repair, maintenance and workover
costs and a decline in production taxes 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 increased, in aggregate, 3% from $106,021 in 1994 to $109,252 in
1995. The Partnership paid the managing general partner $93,693 in 1995 and
$87,605 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 $312,969 related to its oil and gas properties during the fourth quarter of
1995.

Depletion was $819,927 in 1995 compared to $1,090,667 in 1994. This represented
a decrease of $270,740, or 25%. Oil production decreased 20,455 barrels in 1995
from 1994, while oil reserves of barrels were revised downward by 213,660
barrels, or 11%.

A gain on abandoned property of $8,964 was recognized in 1995. This gain was the
result of proceeds received from equipment salvage on one fully depleted
abandoned property. Abandoned property costs of $6,974 were incurred on the one
well plugged and abandoned in 1995. There was no abandonment activity in 1994.

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 $168,374 during the year
ended December 31, 1996 from the year ended December 31, 1995. The increase was
due to an increase in oil and gas sales, offset by an increase in production
costs paid.

Net Cash Used in Investing Activities

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

Proceeds of $8,529 were received from the sale of oil and gas equipment on one
well abandoned in a prior year. Proceeds of $8,964 were received from the
salvage of equipment on one well abandoned during 1995.

Proceeds of $2,326 were received in 1995 for the sale of mineral rights on an
undeveloped property.

Net Cash Used in Financing Activities

Cash was sufficient in 1996 for distributions to the partners of $1,833,192 of
which $1,814,872 was distributed to the limited partners and $18,320 to the
managing general partner. In 1995, cash was sufficient for distributions to the
partners of $1,592,621 of which $1,576,695 was distributed to the limited
partners and $15,926 to the managing general partner.

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.

ITEM 11. Executive Compensation

The Partnership does not have any directors or officers. Management of the
Partnership is vested in PPDLP, the managing general partner. The Partnership
participates in oil and gas activities through an income tax partnership (the
"Program") pursuant to the Program agreement. Under the Program agreement, PPDLP
and Parker & Parsley Employees 90-B Conv., L.P. ("EMPL") pay approximately 10%
of the Partnership's acquisition, drilling and completion costs and
approximately 15% during the first three years and approximately 20% after three
years of its operating and general and administrative expenses. In return, they

are allocated approximately 15% during the first three years and approximately
20% after three years of the Partnership's revenues. See Notes 6 and 9 of Notes
to Financial Statements included in "Item 8. Financial Statements and
Supplementary Data" below for information regarding fees and reimbursements paid
to the managing general partner or its affiliates by the Partnership.

PPUSA's current executive officers and other employees are general partners of
EMPL which serves as a co-general partner of the Program. Under this
arrangement, EMPL pays approximately 2-1/2% of the Partnership's acquisition,
drilling and completion costs and approximately 3.75% during the first three
years and approximately 5% after three years of its operating and general and
administrative expenses. In return, EMPL is allocated approximately 3.75% during
the first three years and approximately 5% after three years of the
Partnership's revenues. EMPL does not receive any fees or reimbursements from
the Partnership.

The Partnership does not directly pay any salaries of the executive officers of
PPUSA, but does pay a portion of PPUSA's general and administrative expenses of
which these salaries are a part. See Note 6 of Notes to Financial Statements

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

Note 1. Organization and nature of operations

Parker & Parsley 90-B, L.P. (the "Partnership") is a limited partnership
organized in 1990 under the laws of the State of Delaware.

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 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

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.

Organization costs - Organization costs are capitalized and amortized on
the straight-line method over 60 months.

Net income per limited partnership interest - The net income 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.

Reclassifications - Certain reclassifications have been made to the 1995
financial statements to conform to the 1996 financial statement presentation.

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
recognized non-cash charges of $61,080 and $312,969 related to its oil and gas
properties during 1996 and 1995, respectively.

Note 4. Income taxes

The financial statement basis of the Partnership's net assets and
liabilities was $3,468,567 greater than the tax basis at December 31, 1996.

The following is a reconciliation of net income per statements of

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.

--------- ---------
Net proved reserves at December 31, 1996 1,892,949 5,874,569
========= =========
The estimated present value of future net revenues of proved reserves,
calculated using December 31, 1996 prices of $24.75 per barrel of oil and $3.71
per mcf of gas, discounted at 10% was approximately $16,437,000 and undiscounted
was $33,657,000 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:

1996 1995 1994
------ ------ ------
Genesis Crude Oil, L.P. 63% 65% 63%
Western Gas Resources, Inc. 13% 10% -
GPM Gas Corporation - 10% 17%

The above customers represent 70% of total accounts receivable at
December 31, 1996.
26

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 $297,718 due from Genesis at December 31, 1996.

Note 9. Organization and operations

The Partnership was organized October 5, 1990 as a limited partnership
under the Delaware 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:

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
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
