                                     PART I

ITEMS 1. AND 2.  BUSINESS AND PROPERTIES
GENERAL

    Sun  Energy Partners, L.P. (Sun Energy  Partners) engages exclusively in the
exploration and development  of oil  and gas in  the United  States. Sun  Energy
Partners  is controlled  by Oryx  Energy Company  and certain  of its affiliates
(together the Company), which  is the managing general  partner. As of  December
31, 1993, the Company owned 98 percent of Sun Energy Partners. The remaining two
percent  interest is comprised  of limited partnership  interests held by public
unitholders in the form of depositary units (Units). Eighty-five percent of  the
Company's  Board  of Directors  must approve  any  additional issuance,  sale or
transfer of units which  would reduce the  Company's holdings below  eighty-five
percent  of the outstanding units. Sun  Energy Partners sold 8.7 million limited
partnership units during 1993 and 11.5 million limited partnership units  during
1991 to the Company. It does not expect to sell any additional units in 1994.

    Sun  Energy Partners'  business is  conducted through  Sun Operating Limited
Partnership,  a  Delaware  limited  partnership,  and  several  other  operating
partnerships   (collectively,  the  Operating  Partnerships).   In  all  of  the
partnerships which  comprise the  Operating  Partnerships, Sun  Energy  Partners
holds a 99 percent interest as the sole limited partner, while the Company holds
a one percent interest as the managing general partner.

    Sun  Energy  Partners  and  the  Operating  Partnerships  (collectively, the
Partnership), are managed  by the  Company. The holders  of limited  partnership
units  have no power to direct or participate in the control of the Partnership.
The Company makes all  decisions regarding exploration, development,  production
and  marketing  for  properties  belonging  to  the  Partnership,  all decisions
regarding the sale  of less  than substantially all  of such  properties or  the
acquisition  of properties by the Partnership  and all other decisions regarding
the Partnership's business or operations.

    The Partnership has no officers or employees. Officers and employees of  the
Company perform all management functions required for Sun Energy Partners. As of
December  31,  1993,  the  number  of full-time  employees  of  the  Company was
approximately 1,500.

    The Partnership's  strategy  is  to  continue to  target  as  future  growth
opportunities  those areas  where its  advanced technological  capabilities will
have the  greatest impact.  The  Partnership is  focusing  its efforts  on  high
potential Gulf of Mexico prospects, including the continental shelf, subsalt and
flex trend.

RESERVES

    As of December 31, 1993, the Partnership's proved reserves were an estimated
257 mmb of liquids and an estimated 1,417 bcf of natural gas which represents an
aggregate  of 493 mmeb of reserves. More information on the estimated quantities
of proved oil and gas reserves and  information on proved developed oil and  gas
reserves,  as  well  as  information  concerning  the  standardized  measure  of
<PAGE>
discounted future net cash flows from estimated production of proved oil and gas
reserves (Standardized Measure),  are presented in  the "Consolidated  Financial
Statements  -- Supplementary  Financial and  Operating Information"  included in
Item 8 herein. The Partnership files estimates of oil and gas reserve data  with
various governmental regulatory authorities and agencies. The basis of reporting
reserves  to these authorities and agencies in some cases may not be comparable.
However, the difference in estimates does not exceed five percent.

    The Partnership's  production is  exclusively in  the United  States and  in
1993,  the  Partnership produced  54.5  mmeb. The  Partnership  seeks production
replacement through a balanced  approach that combines exploration,  development
and  acquisition. In 1993, the Partnership replaced 85 percent of its production
at a finding, development and acquisition cost of $4.75 per eb.

OFFSHORE

    EXPLORATION

    As of December 31, 1993, the  Partnership held 384 thousand net  undeveloped
acres  offshore,  as compared  to  295 thousand  as  of December  31,  1992. The
Partnership owns  interests  in 173  Gulf  of Mexico  blocks  of which  124  are
undeveloped. In 1993, the Partnership spent $6.5 million to acquire interests in
20 blocks.

    As  of December 31, 1993,  the Partnership was in  the process of drilling 2
gross and 2  net exploratory wells.  The Partnership drilled  4 net  exploratory
wells offshore in 1993 and 4 in 1992.

    The  Partnership's offshore exploration program, concentrated in the Gulf of
Mexico, has  three  major  objectives.  The first  objective  is  the  gas-prone
prospects  in  the  shallower water  depths  (less  than 600  feet).  The second
objective is in the subsalt which covers  part of the continental shelf and  the
deeper  part of  the Gulf of  Mexico in water  depths ranging from  300 to 2,000
feet. The third objective is in the deeper waters of the flex trend area (600 to
2,000  feet).  Advanced  hydrocarbon  indicator  and  three-dimensional  seismic
technologies  are being  used to explore  undeveloped acreage as  well as blocks
held by production.

    The Partnership owns a 99 percent interest in the four block High Island 384
unit. The High Island 384 unit is composed  of blocks 378, 379, 384 and 385  and
is  located approximately 112 miles off the Texas coast in water with an average
depth of  approximately 360  feet. In  1993, the  Partnership announced  an  oil
discovery  in High  Island 379. The  HI-A-379 #1 discovery  well encountered 179
feet of oil pay from  three Pleistocene sands between  4,600 and 5,130 feet.  In
the  early part of 1994,  the Partnership announced an  oil and gas discovery in
High Island 385. The High Island 385 discovery encountered 80 feet of net pay in
two  Basal  Nebraskan  sands  between  14,300  and  14,410  feet.  The  combined
production  from the two discoveries is expected to peak at approximately 20 meb
per day. This new development is expected to begin production in 1995.

    PRODUCTION AND DEVELOPMENT

    Average daily production of crude oil  and condensate offshore was 8.5,  7.1
and  5.3 mb  in 1993,  1992 and  1991. Average  daily production  of natural gas
offshore was 191, 179 and 183 mmcf in 1993, 1992 and 1991. The increase in  1993
natural gas production was due primarily to the Mississippi Canyon unit.

    The  Partnership began  production from its  Mississippi Canyon  400 unit in
July 1993. The unit lies in water depths  ranging from 600 to 2,100 feet off  of
the  Louisiana coast. The Partnership used subsea completions to tie three wells
into an existing platform. Production from this unit reached 60 mmcf of gas  per
day. The Partnership has a 99 percent working interest in this project.

    Delineation  of Garden Banks 260 located in  the deep flex trend area of the
Gulf of Mexico is continuing. First production is anticipated in 1998 at a gross
rate of about 60,000 eb/d. The Partnership owns a 50 percent interest in a three
block area.

                                       2
<PAGE>
    Viosca Knoll 826, lies  80 miles off  the Alabama coast  in water depths  of
1,500  to 2,500  feet. First production  is anticipated  in 1996 or  1997 with a
gross peak rate of 20,000 to 30,000  eb/d. The Partnership operates the 4  block
Viosca Knoll unit and owns a 50 percent interest.

    As  of December 31, 1993,  the Partnership was in  the process of drilling 7
gross and 2  net development wells.  The Partnership drilled  8 net  development
wells  offshore in 1993 and 2 in 1992. Of the 8 net development wells drilled in
1993, 5 were successful.

ONSHORE

    The onshore area continues to be the major contributor of production volumes
and  cash  flow.  While  the  Partnership  continues  to  pursue  workovers  and
development  opportunities  to  enhance  its  production  and  cash  flows, ED&A
spending for onshore in total has declined substantially since 1991 as a  result
of the redeployment of the Partnership's resources.

    EXPLORATION

    The  decrease of  383 thousand  net undeveloped  acres from  812 thousand at
December 31,  1992  to  429  thousand  at  December  31,  1993  is  due  to  the
relinquishment   of  non-producing  properties  as  part  of  the  Partnership's
strategic plan to reduce onshore exploration.

    The Partnership drilled 3 fewer net  exploratory wells onshore in 1993  than
1992 and 17 fewer in 1992 than in 1991.

    PRODUCTION AND DEVELOPMENT

    Average  daily production of crude oil and condensate onshore was 46.8, 55.7
and 69.7  mb  in 1993,  1992  and  1991. The  decrease  in 1993  crude  oil  and
condensate  production compared  to 1992  and in 1992  compared to  1991 was due
primarily to asset sales  and normal declines. Average  daily net production  of
natural  gas onshore  was 326,  399 and  461 mmcf  in 1993,  1992 and  1991. The
decrease in 1993 natural gas production compared to 1992 and in 1992 compared to
1991 was due primarily to divestments.

    As of December 31, 1993, the Partnership  was in the process of drilling  or
participating  in the drilling of 14 gross  and 8 net development wells onshore.
Of the 45 net development wells drilled onshore, 44 were successful during 1993.
Net development wells  drilled onshore during  1993 decreased by  12 from 57  in
1992  and  decreased  in  1992 by  42  from  99  in 1991  primarily  due  to the
de-emphasis of onshore activities.

    As part of an asset sale program, the Partnership sold substantially all its
gas processing plant  business in  1992. The Partnership's  remaining gas  plant
business at December 31, 1993 consisted of 11 operated gas processing plants and
interests in 4 others.

</TABLE>

ASSET DISPOSALS

    Assets  are managed on  a portfolio basis. The  Partnership will continue to
buy and sell assets with the intention of upgrading its asset base.

RECOVERY METHODS

    During 1993, the Partnership  obtained 49, 39, and  12 percent of its  crude
production  from primary, secondary and tertiary recovery methods. This compares
to 50, 38 and 12  percent of its crude oil  production in 1992. At December  31,
1993, the Partnership operated or participated in 18 major tertiary oil recovery
programs  that  produced  approximately  6 thousand  net  barrels  of  crude and
condensate daily in 1993.

    The terms  "secondary  recovery" and  "tertiary  recovery" relate  to  those
methods  used to increase the  quantity of crude oil  and condensate and natural
gas that  can be  recovered in  excess  of the  quantity recoverable  using  the
primary energy found in a reservoir. Secondary recovery methods include pressure
maintenance by waterflooding or natural gas injection. Tertiary recovery methods

                                       5
<PAGE>
include injection of carbon dioxide, nitrogen, chemicals, steam or a combination
of  these with natural gas or water. Tertiary and, to a lesser extent, secondary
recovery operations  generally have  higher operating  costs compared  to  those
incurred in primary production efforts.

MARKETING OF OIL AND GAS

    DISTRIBUTION

    Crude  oil, condensate and natural gas  are distributed to end users through
pipelines, barges and/or trucks.  In addition to  end users, purchasers  include
intermediaries   such  as   gatherers,  transporters   and  traders.  Sufficient
distribution systems  exist  and are  readily  available  in the  areas  of  the
Partnership's production to enable the Partnership to effectively market its oil
and gas. In some instances, the Partnership owns an interest in these systems.

    CRUDE OIL AND CONDENSATE

    During 1993, sales to Phibro Energy Company and Meridian Oil Trading totaled
approximately  21 and  16 percent  of the Partnership's  sales of  crude oil and
condensate. No other customer purchased more than 8 percent of the Partnership's
sales of crude oil and condensate.

    Since most of  the Partnership's  crude oil  and condensate  is produced  in
areas  where there are other  buyers offering to purchase  at market prices, the
Partnership believes  that the  loss of  any major  purchaser would  not have  a
material  adverse effect on the Partnership's business. In 1993, the ten largest
customers,  including   Phibro  and   Meridian   Oil  Trading,   accounted   for
approximately 68 percent of such sales.

    Currently,   approximately  55  percent  of   sales  are  made  pursuant  to
arrangements that are cancelable upon 30 days' written notice by the Partnership
or the purchaser,  with substantially  all of  the remainder  of the  production
being sold pursuant to contracts of varying terms of up to one year in length.

    NATURAL GAS

    The  Partnership's  natural  gas  marketing strategies  are  designed  to be
effective in  the current  competitive environment.  Sales of  natural gas  into
short-term  markets averaged  57 percent  of total  sales. However,  by year-end
nearly 50 percent of total sales were contracted to end-users of natural gas  on
a  long-term  basis. The  Partnership's strategy  is to  sell to  end-users that
possess firm transportation rights from the producing basin to the city gate  on
major  interstate pipelines. Contract length of these term sales ranges from one
to ten years.

    During 1993, no individual customer accounted for more than five percent  of
the  Partnership's natural  gas sales. The  ten largest  customers accounted for
approximately 30 percent of total gas sales during 1993.

    HEDGING

    Because  of  the  volatility  of   oil  and  gas  prices,  the   Partnership
periodically  enters into crude oil and natural gas hedging activities (See Note
1 to the Consolidated Financial Statements included in Item 8 herein).

REGULATION

    GENERAL

    The oil and gas industry is subject to regulation by the public policies  of
national,  state and local governments relating to  such matters as the award of
exploration and  production  interests,  the  imposition  of  specific  drilling
obligations, environmental protection controls, control over the development and
abandonment  of a field (including restrictions on production and abandonment of
production facilities). The industry is also subject to the payment of royalties
and taxes, which tend to  be high compared to  those levied on other  commercial
activities.  The Partnership cannot predict the  impact of future regulatory and
taxation initiatives.

                                       6
<PAGE>
    NATURAL GAS

    The domestic gas industry remains  under federal regulation pursuant to  the
Natural  Gas Act  and the Natural  Gas Policy Act.  However, as a  result of the
Natural Gas Decontrol Act,  wellhead regulation of gas  prices ended January  1,
1993.

    ENVIRONMENTAL MATTERS

    The  Partnership  is subject  to,  and makes  every  effort to  comply with,
various  environmental  quality  control  regulations  of  national  and   local
governments.  Although environmental requirements can  have a substantial impact
upon the energy industry, generally these  requirements do not appear to  affect
the  Partnership any differently or  to any greater or  lesser extent than other
exploration and production companies.

    The Partnership has been named as  a potentially responsible party (PRP)  at
four  sites pursuant to the  Comprehensive Environmental Response, Compensation,
and Liability Act of 1980,  as amended. At two  of these sites, the  Partnership
has  been named as a de minimis party  and therefore expects its liability to be
small. At a third site, the Partnership is reviewing its options and anticipates
that it will participate in steering committee activities with the Environmental
Protection  Agency  (EPA).  At  the  fourth  and  largest  site,  the  Operating
Industries,  Inc.  site in  California, the  Partnership  has participated  in a
steering committee consisting of 139 companies. The steering committee and other
PRP's previously entered into two partial consent decrees with the EPA providing
for remedial  actions which  have been  or  are to  be completed.  The  steering
committee  has recently successfully  negotiated a third  partial consent decree
which provides  for  the  following  remedial actions:  a  clay  cover,  methane
capturing  wells, and leachate destruction facilities. The remaining work at the
site involves groundwater evaluation and long-term operation and maintenance.

    Based on the facts outlined above and the Partnership's ongoing analyses  of
the actions where it has been identified as a PRP, the Partnership believes that
it  has accrued sufficient reserves to absorb  the ultimate cost of such actions
and that  such  costs will  not  have a  material  impact on  the  Partnership's
financial condition or results of operations. While liability at superfund sites
is  typically joint and several,  the Partnership has no  reason to believe that
defaults by other PRP's will result  in liability of the Partnership  materially
larger than expected.

COMPETITION

    The  oil  and  gas  industry is  highly  competitive.  Integrated companies,
independent companies and individual producers and operators are active  bidders
for  desirable oil and  gas properties, as  well as for  the equipment and labor
required to  operate and  develop  such properties.  Although several  of  these
competitors  have financial  resources substantially  greater than  those of the
Partnership, management  believes  that the  Partnership  is in  a  position  to
compete effectively.

    The  availability  of  a ready  market  for  the Partnership's  oil  and gas
production depends on numerous factors  beyond its control, including the  level
of  prices and consumer demand, the extent  of worldwide oil and gas production,
the cost  and availability  of  alternative fuels,  the  cost and  proximity  of
pipelines  and other transportation facilities, regulation by national and local
authorities  and   the  cost   of  compliance   with  applicable   environmental
regulations.

TECHNOLOGY

    The  Partnership's exploration, development and production activities depend
upon the use of applied technology. In support of this, the Partnership, through
the Company, has 67 engineers, geoscientists, technicians and support  personnel
applying  the  technology  used  in the  exploration  for,  and  development and
production of, energy  resources. The Partnership's  expenditures on  technology
activities,  including its share  of the Company's  employee-related costs, were
$15 million, $15  million and $13  million for  the years 1993,  1992 and  1991,
respectively.

                                       7
<PAGE>
CONFLICTS OF INTEREST

    Certain  conflicts of  interest may arise  as a result  of the relationships
between the  Company and  the Partnership.  The directors  and officers  of  the
Company  have fiduciary duties to manage the Company in the best interest of its
stockholders. The Company, as managing general partner of the Partnership, has a
fiduciary duty to manage the Partnership in a manner that is fair to the  public
unitholders.  The duty of the  directors of the Company  to its stockholders may
therefore come  into conflict  with the  duties  of the  Company to  the  public
unitholders.

    The  Audit  Committee  of  the  Board of  Directors  of  the  Company (Audit
Committee), none  of whose  members is  affiliated with  the Company  except  as
company  directors or stockholders or as  holders of units, reviews policies and
procedures developed by the Company for dealing with various matters as to which
a conflict  of  interest  may  arise. The  Audit  Committee  also  monitors  the
application of such policies and procedures.

OTHER

    The  Partnership's financial condition and  business operations are affected
from time  to time  by political  developments and  laws and  regulations  which
relate  to such  matters as  production, taxes,  property, imports,  pricing and
environmental controls. The Company makes no representations as to future events
and developments which could affect  the Partnership's operations and  financial
condition.  Oil and gas  prices are subject to  international supply and demand.
Political developments (especially in the Middle East) and the decisions of OPEC
can particularly  affect  world oil  supply  and oil  prices.  Furthermore,  the
Partnership's business and financial condition could be affected by, among other
things, competition, future price changes or controls, material and labor costs,
legislation, transportation regulations, tariffs, embargoes and armed conflicts.

ITEM 3.  LEGAL PROCEEDINGS

    The  Partnership  is  involved  in  a  number  of  legal  and administrative
proceedings arising in the ordinary course of its oil and gas business. Although
the ultimate outcome of these proceedings cannot be ascertained at this time, it
is  reasonably  possible  that  some  of  the  proceedings  could  be   resolved
unfavorably  to the  Partnership. Management  of the  Company believes  that any
liabilities which may arise would not  be material in relation to the  financial
position  of  the  Partnership at  December  31,  1993. The  Company  intends to
maintain liability and other insurance for the Partnership of the type customary
in the oil  and gas  business with  such coverage  limits as  the Company  deems
prudent.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF UNITHOLDERS

    None.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
       CONDITION AND RESULTS OF OPERATIONS

    Management's discussion and analysis of the Partnership's financial position
and results of operations follows. This discussion should be read in conjunction
with  the Consolidated Financial Statements and Selected Financial Data included
in this report.

                                       9
<PAGE>
BUSINESS CLIMATE

    The Partnership's production is approximately 60 percent gas and 40  percent
oil  on an equivalent basis. The fundamentals  in the U.S. gas market are better
today than they  have been  since the mid  1980's. Excess  deliverability is  no
longer  a problem due to solid growth in demand and reduced supply, although oil
prices have constrained  the upward  movement of gas  prices. The  Partnership's
realized gas price in 1993 was $1.96 per mcf or 14 percent higher than the $1.72
per mcf realized in 1992.

    The  fundamentals in worldwide oil markets  continue to reflect an excess of
supply over demand. OPEC members have not restrained their production in a  weak
global  economy  and prices  have fallen  to  five-year lows.  The Partnership's
realized oil price in 1993 fell by $2.55 per barrel to $15.96 per barrel, or  14
percent  less than the 1992 price. The crude price in the fourth quarter of 1993
was $5.59 per barrel lower than the fourth quarter of 1992. Prices in early 1994
have not shown any significant improvement from levels realized in late 1993.

RESULTS OF OPERATIONS

    The Partnership's net income in 1993 was  $44 million, or $.11 per unit,  as
compared to net income of $120 million, or $.29 per unit, in 1992 and net income
of $114 million, or $.28 per unit in 1991.

    Lower  net income in 1993 as compared to 1992 was caused by lower production
volumes and a lower average oil price partially offset by a higher average price
for gas and  lower costs and  expenses. Additionally, results  for 1992  include
$115  million in gains from the sale of assets while results for 1993 include $7
million in losses from  asset disposals. Oil volumes  were 13 percent lower  and
gas  volumes  were  11  percent  lower in  1993  resulting  from  divestments of
producing properties in 1992. The Partnership's hedging activities decreased the
overall price it received by $.09 per mcf of gas in 1993 and by $.06 per  barrel
of oil and $.02 per mcf in 1992. Total costs and expenses decreased $185 million
or 23 percent to $632 million in 1993 from $817 million in 1992. The Partnership
is  continuing to review its cost structure in an effort to further reduce costs
at all levels.

    The improvement in net income for 1992 as compared to 1991 is reflective  of
a  $148 million decrease in  costs and expenses, substantially  offset by a $142
million decrease  in total  revenues. The  decrease in  costs and  expenses  was
driven  by the cost cutting provisions of the restructuring which began in 1991,
but were partially offset by a $62 million provision recognized in 1992 for  the
early relinquishment of non-producing properties. The decrease in total revenues
was  comprised  of  a $146  million,  or 16  percent,  decrease in  oil  and gas
revenues, partially  offset by  a $4  million increase  in other  revenues.  The
decrease  in  oil and  gas revenues  is reflective  of a  13 percent  decline in
volumes, due to asset sales and normal declines, and continued price volatility.
The increase  in  other revenues  is  essentially  comprised of  a  $40  million
increase in gains on sales of assets, partially offset by a $27 million decrease
in   gas  plant  margins  caused  by  the  sale  of  substantially  all  of  the
Partnership's gas processing plants.

    Average net production of oil in 1993  was 55 thousand barrels daily, or  13
percent  lower than the  average net production  in 1992 of  63 thousand barrels
daily. The average price received for  the Partnership's oil production in  1993
was  $15.96 per barrel, representing a 14 percent decrease from the 1992 average
price of $18.51.

    Average net production of oil in 1992  was 63 thousand barrels daily, or  16
percent  lower than average net production in 1991 of 75 thousand barrels daily.
The average price  received for  the Partnership's  oil production  in 1992  was
$18.51  per barrel,  representing a  11 percent  decrease from  the 1991 average
price of $20.88.

    Average net production of gas in 1993  was 517 million cubic feet daily,  or
11  percent lower than average net production for 1992 of 578 million cubic feet
daily. The Partnership  received an average  price of $1.96  per thousand  cubic
feet  for its gas production  in 1993 compared to an  average price of $1.72 per
thousand cubic feet in 1992, representing a 14 percent increase.

                                       10
<PAGE>
    Average net production of gas in 1992  was 578 million cubic feet daily,  or
10  percent lower than average net production of 644 for 1991. The average price
received for the  Partnership's gas production  in 1992 was  $1.72 per  thousand
cubic feet compared to $1.55 per thousand cubic feet in 1991, representing an 11
percent increase.

LIQUIDITY AND CAPITAL RESOURCES

    In 1991, cash flow from operating activities decreased $102 million compared
to  1990 primarily  due to  lower oil  prices offset  by favorable  increases in
working capital components. Investing activities provided $371 million more cash
and cash  equivalents  in  1991  largely  due to  a  $325  million  increase  in
divestment  proceeds and  a $52  million reduction  in capital  expenditures. In
1991, financing activities used $725 million more cash and cash equivalents  due
to an increase in debt repayments of $547 million and a reduction in the sale of
limited partnership units of $163 million.

    In 1992, cash flow from operating activities decreased $208 million compared
to  1991 primarily due to lower sales  volumes and oil prices, and reductions in
current liabilities, offset in part by an increase in gas prices and  reductions
in  costs and expenses. Cash flow provided from investing activities declined by
$28 million, reflecting a  $258 million decrease  in proceeds from  divestments,
partially  offset by a $206 million  decrease in capital expenditures. Cash flow
used for financing  activities decreased  by $445 million  in 1992,  principally
reflective  of  declines of  $361  million and  $175  million in  cash  used for
repayments of long-term debt and cash distributions paid to unitholders,  offset
in  part by  a $101  million decrease  in cash  flow provided  from the  sale of
limited partnership units.

    In 1993, cash flow from operating activities increased $68 million from 1992
primarily due to favorable increases in cash from working capital components,  a
higher  average price for gas  and lower costs and  expenses partially offset by
lower production  volumes and  a lower  average price  for oil.  Cash flow  from
investing  activities  used  $148 million  in  1993 compared  to  providing $252
million in 1992. Proceeds from divestments were $298 million lower in 1993 while
capital expenditures  increased by  $99 million.  Cash flow  used for  financing
activities  decreased by $305 million in 1993 primarily because of the repayment
of $239 million in long-term debt in  1992 compared to repayment of $19  million
in 1993.

    In  the fourth quarter of 1993, the  Company's Board of Directors elected to
change its investment policy concerning ownership of the Partnership.  Effective
in  1994, the policy  of distributing all  cash to unitholders  and then selling
newly issued  Partnership units  to  the Company  to  fund capital  outlays  was
changed. The Partnership now funds its capital outlays from internally generated
funds and makes distributions of only that cash remaining after such outlays.

    The  Partnership's spending  levels will be  governed by its  cash flow from
operating activities which will  continue to be affected  by prevailing oil  and
gas  prices, cost  levels and production  volumes. A shortfall  in expected cash
flow from operating  activities may  require adjustment of  the business  plans.
Options  include deferral of discretionary capital  expenditures and the sale of
Partnership units.  The Partnership's  long-term cash  generation capability  is
ultimately tied to the value of its proved reserve base.

RESERVE REPLACEMENT

    The  ability to sustain cash  flow is dependent, among  other things, on the
level of the Partnership's  oil and gas  reserves, oil and  gas prices and  cost
containment.  Replacement of proved reserves through extensions and discoveries,
improved recovery, purchases and  revisions to prior  reserve estimates in  1993
was  74 percent of liquids production and  93 percent of gas production. Reserve
replacement rates of liquids and gas were 17  and 68 percent in 1992 and 79  and
81 percent in 1991.

ENVIRONMENTAL

    The   Partnership's  oil  and  gas   operations  are  subject  to  stringent
environmental regulations. The Company is  dedicated to the preservation of  the
environment and has committed significant resources

                                       11
<PAGE>
to  comply with such regulations.  Although the Partnership has  been named as a
potentially responsible party at sites  related to past operations, the  Company
believes  the Partnership is in  general compliance with applicable governmental
regulations and  that the  potential costs  to  it, in  the aggregate,  are  not
material  to its  financial condition. However,  risks of  substantial costs and
liabilities are inherent in the oil and gas business. Should other  developments
occur,   such  as  increasingly  strict   environmental  laws,  regulations  and
enforcement policies  or claims  for damages  resulting from  the  Partnership's
operations, they could result in additional costs and liabilities in the future.
See Note 12 to the Consolidated Financial Statements.

CASH DISTRIBUTION POLICY

    In  the fourth quarter of 1993, the  Company's Board of Directors elected to
change  the  Company's  investment  policy  concerning  purchase  of  additional
Partnership  units.  Effective in  1994, the  Company  will no  longer routinely
purchase newly issued Partnership  units to fund capital  outlays. As a  result,
the  Partnership now funds  its capital outlays  from internally generated funds
and make distributions of only that cash remaining after such outlays. The newly
adopted policy will reduce the cash paid  to unitholders, but will also end  the
ownership dilution caused by the issuance of additional units.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Partners of Sun Energy Partners, L.P. and the Board of Directors of Oryx
Energy Company:

    We have audited the consolidated balance sheets of Sun Energy Partners, L.P.
and  its  Subsidiaries  as  of  December 31,  1993  and  1992,  and  the related
consolidated statements of income and cash flows for each of the three years  in
the  period  ended  December  31,  1993.  These  financial  statements  are  the
responsibility of Oryx  Energy Company'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 consolidated  financial position  of Sun  Energy
Partners,  L.P. and its Subsidiaries  as of December 31,  1993 and 1992, and the
consolidated results of their  operations and their cash  flows for each of  the
three  years in the period ended December  31, 1993 in conformity with generally
accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    ORGANIZATION AND CONTROL

    Sun  Energy  Partners,  L.P.  (Sun  Energy  Partners),  a  Delaware  limited
partnership, was formed on October 1, 1985 and prior to December 1, 1985 had  no
operations  and nominal assets and equity. Effective as of December 1, 1985, Sun
Energy Partners succeeded  to all the  domestic oil and  gas operations of  Oryx
Energy  Company and certain of its affiliates (collectively, the Company). These
operations consist of  the exploration and  development of oil  and natural  gas
reserves in the United States.

    Sun  Energy Partners  is controlled  by the  Company, which  is the managing
general partner. As of December 31, 1993, the Company had a partnership interest
of 98  percent  in  Sun  Energy Partners.  The  remaining  two  percent  limited
partnership  interest is  held by public  unitholders in the  form of depositary
units. Eighty-five percent of the Company's Board of Directors must approve  any
additional  issuance, sale or transfer of units which would reduce the Company's
holdings in Sun Energy Partners below eighty-five percent.

    Sun Energy Partners  operates through Sun  Operating Limited Partnership,  a
Delaware   limited  partnership,   and  several   other  operating  partnerships
(collectively, the Operating  Partnerships). In  all of  the partnerships  which
comprise  the Operating  Partnerships, Sun  Energy Partners  holds a  99 percent
interest as the  sole limited  partner, while the  Company holds  a one  percent
interest as the managing general partner.

    Sun  Energy  Partners  and  the  Operating  Partnerships  (collectively, the
Partnership) have no officers  or employees. The officers  and employees of  the
Company perform all management functions.

    BASIS OF PRESENTATION

    The Partnership's consolidated financial statements have been prepared using
the  proportionate method  of consolidation for  Sun Energy Partners  and its 99
percent interest in  the Operating Partnerships.  Such financial statements  are
prepared  in accordance with  generally accepted accounting  principles which is
different  from  the  basis  used  for  reporting  taxable  income  or  loss  to
unitholders.

    CASH AND SHORT-TERM INVESTMENTS

    The Partnership considers highly liquid investments with original maturities
of less than three months to be cash equivalents. Cash equivalents are stated at
cost which approximates market value.

    PROPERTIES, PLANTS AND EQUIPMENT

    The  successful efforts method of accounting  is followed for costs incurred
in oil and gas operations.

    CAPITALIZATION POLICY.   Acquisition  costs are  capitalized when  incurred.
Costs  of unproved properties  are transferred to  proved properties when proved
reserves are  added. Exploration  costs,  including geological  and  geophysical
costs  and costs of carrying unproved  properties, are charged against income as
incurred. Exploratory drilling costs are  capitalized initially; however, if  it
is  determined  that an  exploratory  well did  not  find proved  reserves, such
capitalized costs  are charged  to expense,  as dry  hole costs,  at that  time.
Development  costs are capitalized. Costs incurred to operate and maintain wells
and equipment are expensed.

    LEASEHOLD IMPAIRMENT AND DEPRECIATION, DEPLETION AND AMORTIZATION.  Periodic
valuation provisions for impairment of capitalized costs of unproved  properties
are expensed.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

1)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    The   acquisition   costs  of   proved  properties   are  depleted   by  the
unit-of-production  method  based  on  proved  reserves  by  field.  Capitalized
exploratory  drilling costs which result in  the addition of proved reserves and
development costs are amortized by the unit-of-production method based on proved
developed reserves by field.

    DISMANTLEMENT, RESTORATION AND ABANDONMENT COSTS.  Estimated costs of future
dismantlement, restoration  and  abandonment  are  accrued  as  a  component  of
depreciation,  depletion and amortization  expense; actual costs  are charged to
the accrual.

    RETIREMENTS.   Gains  and  losses  on the  disposals  of  fixed  assets  are
generally  reflected  in  income. For  certain  property groups,  the  cost less
salvage  value  of  property  sold  or  abandoned  is  charged  to   accumulated
depreciation,  depletion and amortization except that gains and losses for these
groups are taken into income for unusual retirements or retirements involving an
entire property group.

    CAPITALIZED INTEREST

    The Partnership  capitalizes interest  costs  incurred as  a result  of  the
acquisition and installation of significant assets.

    INCOME TAXES

    The   Operating  Partnerships  and  Sun   Energy  Partners  are  treated  as
partnerships for income tax  purposes and, as  a result, income  or loss of  the
Partnership  is includable  in the  tax returns  of the  individual unitholders.
Accordingly, no recognition  has been  given to  income taxes  in the  financial
statements.

    At  December 31, 1993, 1992 and  1991, the Partnership's financial reporting
bases of  assets  and liabilities  exceeded  the tax  bases  of its  assets  and
liabilities  (net temporary differences)  by $1,049 million,  $1,077 million and
$1,121 million.

    CASH FLOWS

    For purposes of  reporting cash  flows, cash and  cash equivalents  includes
cash,  highly liquid  investments with remaining  maturities of  less than three
months (see  "Cash  and Short-Term  Investments",  above) and  advances  to/from
affiliate.

    Associated  with the sale of the  Midway-Sunset Field and related facilities
in 1991, the purchaser  assumed $53 million of  Partnership debt. In  accordance
with  Statement of  Financial Accounting  Standards No.  95, "Statement  of Cash
Flows,"  non-cash  transactions  are  not  reflected  within  the   accompanying
Consolidated  Statements of Cash Flows (see Note 3 to the Consolidated Financial
Statements). Interest paid totaled $13 million,  $45 million and $57 million  in
1993, 1992 and 1991.

    SALES OF OIL AND GAS

    Sales  of oil  and gas are  recorded on the  entitlement method. Differences
between  actual  production  and  entitlements   result  in  amounts  due   when
underproduction occurs and amounts owed when overproduction occurs.

    During  1993, sales of  oil to the Partnership's  top two purchasers totaled
approximately 21 and 16 percent of oil revenue. During 1992, sales of oil to the
Partnership's top purchasers totaled approximately 13, 11 and 10 percent. During
1993 and 1992, no individual customer accounted  for more than 5 percent of  the
Partnership's  gas sales.  The Partnership believes  that the loss  of any major
purchaser would not have a material adverse effect on its business.

1)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    FINANCIAL INSTRUMENTS

    The difference between the values  calculated as prescribed by Statement  of
Financial  Accounting Standards (SFAS) No. 107, "Disclosures about Fair Value of
Financial Instruments,"  of the  Partnership's financial  instruments and  their
carrying value is not material.

    FUTURES TRADING ACTIVITY

    The  Partnership, from time to time,  enters into futures contracts to hedge
the impact of price  fluctuations on crude and  natural gas production.  Futures
trading  activity decreased oil  and gas revenue  by $17 million  in 1993 and $7
million in  1992. At  December 31,  1993, the  Partnership had  hedged about  30
percent  of its  gas production at  an average floor  of $2.04 per  mmbtu and an
average ceiling of $2.28 per mmbtu.

    ENVIRONMENTAL COSTS

    The Partnership establishes reserves  for environmental liabilities as  such
liabilities are incurred (Note 12).

    CEILING TESTS

    For  ceiling  test  purposes,  the  Partnership  compares  its  undiscounted
standardized measure  of future  net  cash flows  from estimated  production  of
proved  oil and gas reserves to its net properties, plants and equipment related
to oil and gas operations.

    STATEMENT PRESENTATION

    Certain items in years  prior to 1993 have  been reclassified to conform  to
the 1993 presentation.

2)  RELATED PARTY TRANSACTIONS

    ADVANCES TO/FROM AFFILIATE

    The Company has served as the Partnership's lender and borrower of funds and
a  clearing-house for the  settlement of intercompany  receivables and payables.
Deposits earn interest at a rate equal to the rate paid by a major money  market
fund. Demand loans bear interest at a rate based on the prime rate.

    LONG-TERM DEBT DUE AFFILIATE

    The Partnership is indebted to the Company under a 9.75% note due 1994-2001.
In  1992 and 1991 the Partnership prepaid  $213 million and $575 million of such
debt from proceeds  of asset  sales (see Note  8 to  the Consolidated  Financial
Statements).

    DIRECT AND INDIRECT COSTS

    The  Company is reimbursed by the  Partnership for all direct costs incurred
in performing management  functions and  indirect costs  (including payroll  and
payroll  related costs  and the cost  of postemployment  benefits and management
incentive plans)  allocable to  the Partnership.  The full  cost of  direct  and
indirect costs incurred on behalf of the Partnership by the Company is allocated
to  the Partnership based  on services rendered  and extent of  use. Such costs,
which are charged principally to  production cost, exploration cost and  general
and  administrative expense, totaled $104 million, $127 million and $176 million
for the years  1993, 1992 and  1991. The  Company does not  receive any  carried
interests,  promotions, back-ins  or other  similar compensation  as the general
partner of the Partnership.

    INTEREST INCOME

    Interest income  received from  the  Company, which  is reflected  in  other
income  in the consolidated statements of income,  was earned on advances to the
Company and totaled  $5 million,  $9 million and  $11 million  during the  years
1993, 1992 and 1991.

2)  RELATED PARTY TRANSACTIONS (CONTINUED)
    INTEREST COST

    Interest  cost paid to the  Company, which is included  in interest and debt
expense in  the consolidated  statements of  income, was  primarily incurred  on
long-term  debt due  the Company  and totaled $12  million, $43  million and $55
million during the years  1993, 1992 and  1991 (see Note  8 to the  Consolidated
Financial Statements).

3)  CHANGES IN BUSINESS
    Effective  January  31,  1991,  the Partnership  sold  its  interest  in the
Midway-Sunset Field  producing  oil and  gas  assets and  a  steam  cogeneration
facility.  Net proceeds of $529 million from  the sale, including $53 million of
debt assumed by the purchaser, were used to fund capital expenditures and prepay
$575 million of debt.

    In 1991, the Company commenced a major restructuring program (Restructuring)
to reduce the Company's and Partnership's cost structures. The program  outlined
a  plan to sell substantially all of  the Partnership's gas plant business (Note
4) and certain onshore producing oil and gas properties.

    Associated with the Restructuring, the Partnership recognized a $62  million
provision  for the early  relinquishment of certain  non-producing properties in
1992. At  December  31,  1992,  the asset  disposal  program  was  substantially
complete  although from time  to time the Partnership  will have divestments. In
1993, the Partnership completed  asset disposals that  generated $59 million  in
proceeds and generated a loss of $7 million.

4)  OTHER REVENUES
    The components of other revenues were as follows:

    Several  legal  and  administrative  proceedings  are  pending  against  the
Partnership.  Although  the  ultimate  outcome of  these  proceedings  cannot be
ascertained at this time, and it is reasonably possible that some of them  could
be  resolved  unfavorably  to  the  Partnership,  management  believes  that any
liabilities which may arise would not  be material in relation to the  financial
position of the Partnership at December 31, 1993.

11) CASH DISTRIBUTIONS
    Beginning  with the fourth quarter 1993,  Distributable Cash will be reduced
by the cash needed for capital outlays. This policy change will reduce the  cash
paid  to unitholders but will eliminate  the ongoing ownership dilution faced by
unitholders due to Oryx Energy's purchase  of newly issued partnership units  to
fund  Sun Energy's  capital outlays. Distributable  Cash is  defined as revenues
(including interest  income)  less  production  cost;  seismic,  geological  and
geophysical  costs (including related costs); payments of principal and interest
on debt; general  and administrative  expenses including  reimbursements of  the
Company    as    managing    general    partner;    adjustments    for   capital

</TABLE>

    Environmental  cleanup  costs   have  been  accrued   in  response  to   the
identification  of  several sites  that require  cleanup based  on environmental
pollution, some  of  which  have  been designated  as  superfund  sites  by  the
Environmental  Protection Agency (EPA). The Partnership has been designated as a
Potentially Responsible Party (PRP) at a  site in southern California where  the
EPA  is requiring  the PRP's  to undertake  remediation of  the site  in several
phases. The  Partnership  is a  member  of the  group  that is  responsible  for
carrying  out the  first phase of  the work,  which is expected  to take  5 to 8
years. Completion of all phases is estimated to take up to 30 years. The maximum
liability of the group, which is joint and several for each member of the group,
is expected to range from approximately  $450 million to $600 million, of  which
the  Partnership's share is expected to be  approximately $10 million (net of $3
million in recoveries from  third parties). Cleanup costs  are payable over  the
period that the work is completed.

    ESTIMATED NET QUANTITIES OF PROVED OIL AND GAS RESERVES

    Proved   reserves  are   the  estimated  quantities   which  geological  and
engineering data  demonstrate with  reasonable certainty  to be  recoverable  in
future  years from reservoirs under  existing economic and operating conditions.
Proved developed reserves are  the quantities expected  to be recovered  through
existing  wells  with existing  equipment and  operating methods.  These reserve
estimates were  principally  prepared by  Company  engineers and  are  based  on
current  technology  and  economic conditions.  The  Partnership  considers such
estimates to  be reasonable;  however,  due to  inherent uncertainties  and  the
limited  nature  of  reservoir  data,  estimates  of  underground  reserves  are
imprecise and  subject to  change over  time as  additional information  becomes
available.

                                       24

    There  has been no major discovery or  other favorable or adverse event that
has caused a significant change in estimated proved reserves since December  31,
1993.  The  Partnership has  no long-term  supply  agreements or  contracts with
governments or authorities in  which it acts  as producer nor  does it have  any
interest  in oil  and gas  operations accounted  for by  the equity  method. All
reserves are located onshore and offshore within the United States.

   STANDARDIZED MEASURE OF DISCOUNTED FUTURE NET CASH FLOWS
     FROM ESTIMATED PRODUCTION OF PROVED OIL AND GAS RESERVES

    The standardized measure of discounted future net cash flows from  estimated
production  of proved oil and  gas reserves is presented  in accordance with the
provisions of Statement of Financial  Accounting Standards No. 69,  "Disclosures
about    Oil    and   Gas    Producing   Activities"    (SFAS   No.    69).   In

                                       25

computing this data, assumptions other than those mandated by SFAS No. 69  could
produce  substantially  different  results.  The  Partnership  cautions  against
viewing this  information  as  a  forecast  of  future  economic  conditions  or
revenues.

    The  standardized measure has been prepared assuming year-end selling prices
adjusted for future fixed and  determinable contractual price changes,  year-end
development,  production and direct  general and administrative  costs and a ten
percent annual discount rate. No future income tax expense has been provided for
the Partnership  since  it incurs  no  income  tax liability.  (See  Summary  of
Significant  Accounting Policies  -- Income Taxes  in the  Notes to Consolidated
Financial Statements.)
