                                     PART I

ITEMS 1 AND 2. BUSINESS AND PROPERTIES

                                   THE COMPANY

         The  registrant,  Cairn Energy USA, Inc., a Delaware  corporation  (the
"Company"),  was  incorporated on May 5, 1981 in Delaware as "Omni  Exploration,
Inc." On September 29, 1992,  Cairn Energy USA, Inc., an oil and gas exploration
and development company, merged with and into the registrant with the registrant
being the  survivor  (the  "Merger").  Pursuant  to the Merger,  the  registrant
changed its name to "Cairn Energy USA, Inc."

         The Company's  principal  executive offices are located at 8115 Preston
Road, Suite 500, Dallas, Texas 75225 and its telephone number is (214) 369-0316.

                                    BUSINESS

GENERAL

         The Company  explores  for,  develops and produces  natural gas and oil
reserves,  principally  on the Outer  Continental  Shelf  ("OCS") of the Gulf of
Mexico.  The  Company  also  has  interests  in  properties  in  onshore  areas,
principally in the Appalachian  region. At January 1, 1997, the Company's proved
reserves,  as  reviewed  by  the  Ryder  Scott  Company,  independent  petroleum
engineers  ("Ryder  Scott"),  were  estimated  to be  approximately  111.4 BCFE,
consisting  of 82.0 Bcf of natural  gas and 4.9 MMBbls of oil. At the same date,
the present  value of estimated  future net cash flows,  before income taxes and
discounted at 10%, from the Company's  estimated  proved  reserves  ("Discounted
Present Value") was $248.1 million,  with  approximately 97% attributable to its
Gulf of Mexico  proved  reserves.  For a further  discussion  of the  Discounted
Present Value reserve valuation  method,  see the section captioned "Oil and Gas
Reserves."

         The  Company's  strategy is to expand its reserve  base and  production
principally through exploration and associated  development drilling. The OCS of
the Gulf of Mexico is a  well-established  area of oil and gas production  where
the Company's  management and staff have both experience and expertise and where
the  application  of  advances  in  3-D  and  2-D  seismic  and   computer-aided
exploration  technology is  particularly  suited.  Exploration  and  development
activities are directed by a small,  experienced  technical team which makes use
of extensive in-house computer capabilities.

         The Company identifies exploratory prospects by (i) integrating 3-D and
2-D seismic  technology with information about surrounding  geological  features
and (ii) high-grading  prospects that exhibit "bright spot" seismic anomalies by
using extensive computer-aided  geophysical modeling and amplitude versus offset
analysis.

         The Company generally limits  exploration  expenditures to amounts that
can be financed  through cash flows from  operations  and  borrowings  under the
Company's  credit  facility.  The Company's  Board of Directors  must  expressly
approve  expenditures  exceeding  $1,500,000  for any single well. The Company's
strategy  with  respect  to  the  development  of  its  proved  reserves  is  to
concentrate  available  resources on those prospects with the greatest potential
to add to the Company's cash flows from operations while maintaining a diversity
of development projects.

PRINCIPAL AREAS OF OPERATIONS

         All of the  Company's  properties  are  located in the  United  States,
mainly  in the OCS of the  Gulf of  Mexico.  The  Company  also  has  properties
onshore, principally in the Appalachian region.

         The focus of the Company's  current  activity is in the Gulf of Mexico.
The Company's total daily  production in 1996 averaged 27,910 Mcf of gas and 747
Bbls of oil, of which about 96% was from wells located in the Gulf of Mexico. Of
the  Company's  total  proved  reserves of 111.4 BCFE at January 1, 1997,  104.9
BCFE, or approximately

94%, were attributable to properties in the Gulf of Mexico.  The Company's total
capital  expenditures  on oil and gas  properties  in 1996 were  $49.0  million,
virtually all of which were on properties in the Gulf of Mexico.

OIL AND GAS RESERVES

         Ryder  Scott  reviewed  as of January 1, 1997 a report  prepared by the
Company  of  the  net  reserves  attributable  to  the  Company's  oil  and  gas
properties.  The Company  used the results from the Ryder Scott  reserve  review
letter (the "Ryder  Scott  Reserve  Review  Letter") as the  Company's  reserves
estimates.  The average prices used in the  computations  were $3.99 per Mcf for
gas and $23.63 per Bbl of oil.  The  results of the Ryder Scott  Reserve  Review
Letter conform to the definition of proved  reserves  required by the Securities
and Exchange Commission (the "Commission"),  which assumes no change in economic
conditions will occur in the future.

         The  estimates  as of  January 1, 1997 of proved  reserves,  future net
revenues  from proved  reserves and the  Discounted  Present  Value of estimated
future net revenues  from such proved  reserves set forth in this annual  report
were  prepared by the  Company and  reviewed  by Ryder  Scott.  For  purposes of
reviewing such estimates,  Ryder Scott reviewed production data through December
1996 for properties representing 96.2% of the Company's estimated proved net gas
reserves  and 99.7% of the  Company's  estimated  proved net oil and  condensate
reserves and through earlier dates for the balance of the Company's  properties.
In order to calculate the proved  reserve  estimates as of January 1, 1997,  the
Company  and Ryder  Scott  assumed  that  production  for each of the  Company's
properties since the date of the last production data reviewed was in accordance
with the production decline curve previously established for such property.

         There are numerous  uncertainties  inherent in estimating quantities of
proved reserves,  including many factors beyond the control of the Company.  The
reserve  data  set  forth  in this  annual  report  represents  only  estimates.
Reservoir  engineering  is  a  subjective  process  of  estimating   underground
accumulations  of crude oil and  natural gas that cannot be measured in an exact
manner, and the accuracy of any reserve estimate is a function of the quality of
available data and of engineering and geological interpretation and judgment. As
a result,  estimates of different engineers often vary. In addition,  results of
drilling,  testing and  production  subsequent  to the date of an  estimate  may
justify  revision of such  estimate.  Accordingly,  reserve  estimates are often
different  from the  quantities of crude oil and natural gas that are ultimately
recovered.  The  meaningfulness  of such estimates is highly  dependent upon the
accuracy of the assumptions  upon which they were based. In general,  the volume
of  production  from oil and gas  properties  owned by the  Company  declines as
reserves  are  depleted.  Except to the extent the Company  conducts  successful
exploration  and  development   activities  or  acquires  additional  properties
containing  proved  reserves,  or both, the proved  reserves of the Company will
decline as reserves are produced.

         In  accordance  with  Commission  guidelines,   the  estimates  of  the
Company's proved reserves and Discounted Present Value of revenues therefrom are
made using  current  lease and well  operating  costs  estimated by the Company.
Lease  operating  expenses for wells owned by the Company were estimated using a
combination of fixed and variable- by-volume costs consistent with the Company's
experience in the areas of such wells.  For purposes of  calculating  future net
revenues and the  Discounted  Present  Value  thereof,  operating  costs exclude
accounting and  administrative  overhead expenses  attributable to the Company's
working interest in wells operated under joint operating agreements, but include
administrative  costs associated with production offices. The Discounted Present
Value of proved reserves set forth herein should not be construed as the current
market value of the estimated  proved oil and gas reserves  attributable  to the
Company's properties.

OFFSHORE PROPERTIES

         East Cameron Blocks 331/332. These blocks are located 98 miles offshore
Louisiana in 240 feet of water. The Company owns a 40% interest in the shallower
horizons of Block 331 and a 20% interest in the deeper  horizons of both blocks.
The Company  purchased an interest in these blocks in 1991 for $100,000,  and in
1992 proposed the first  exploratory well, which proved to be the discovery well
for the field.  The field  commenced  production in October 1994, and a total of
eleven wells have now been  completed.  During 1996, East Cameron Blocks 331/332
produced  an  average of 9.4 MMcf of gas per day and 504 Bbls of oil per day net
to the Company's  interest,  accounting for  approximately  38% of the Company's
production for the period.  During 1996, three  exploration  wells were drilled,
two successful  and one dry hole.  The two  successful  wells were completed and
commenced  production in late December 1996.  Work planned for 1997 will include
the drilling of one  exploration  well and  sidetracking  two existing wells. In
addition to the drilling operations, two wells will undergo major recompletions.
At January 1, 1997,  the  Company's net proved  reserves in East Cameron  Blocks
331/332 were 34.6 BCFE, with a discounted  present value of approximately  $87.8
million.  Samedan Oil Company  ("Samedan"),  a subsidiary  of Noble  Affiliates,
Inc., is the operator of East Cameron Blocks 331/332.

         East  Cameron   Blocks   349/350/355/356.   The  East  Cameron   Blocks
349/350/355/356  prospect  area is located 110 miles  offshore  Louisiana in 300
feet of water.  The  Company's  interests in Blocks 349 and 355 were acquired in
the 1994 Gulf of Mexico Central Area Lease Sale while the Company's  interest in
Block 356 was acquired in a property swap by the Company in 1994.  The Company's
interest in Block 350 was acquired in the 1995 Gulf of Mexico Central Area Lease
Sale. In May 1995,  the Company  participated  in a new field  discovery on East
Cameron  Block 356.  The field is located 6 miles  south of the  Company's  East
Cameron Block 331/332  complex and was  identified on the Company's 3-D seismic,
which covers both areas.  The discovery  well,  East Cameron 356 #1, was drilled
directionally  from a surface  location on East Cameron  Block 349 to a depth of
7,669 feet and encountered two hydrocarbon  bearing  Pleistocene  sands based on
wireline  log  analysis.   The  well  has  been  suspended  pending   completion
operations.  An exploration  well drilled from the same surface  location as the
356 #1, East Cameron 350 #1, was spud on January 23, 1996. Based on wireline log
analysis,  this well encountered  approximately 270 net feet of oil and gas pay.
Platform  installation  is  scheduled  for  early  April  1997  following  which
completion  of the two existing  wells and the drilling of three  further  wells
will take place. Full production from this complex is expected in the late third
quarter 1997. The Company owns a 37.5% working interest in this block,  which is
operated by Enserch Exploration, Inc. ("Enserch").

         Galveston Blocks 343/363.  Galveston  343/363 field is located 13 miles
offshore  Texas in 65 feet of water.  The  field is  comprised  of two  adjacent
federal  lease blocks  operated by an affiliate  of Seagull  Energy  Corporation
("Seagull").  Production began in 1990.  Natural gas and condensate are produced
from 15 well  completions  on Blocks 343 and 363,  from sands at depths of 7,100
feet to 8,500 feet. The wells on Block 343 produce  through a four pile drilling
and  production  platform.  The well on Block 363  produces  through a  separate
satellite  platform that is tied by flowline to the Block 343 platform.  Gas and
condensate flow from Block 343 to shore through a 16-inch pipeline. During 1996,
the average daily  production net to the Company from this field was 2.9 MMcf of
gas and 8 Bbls of  condensate.  In July 1996,  the A-2 well was worked  over and
completed as a dual gas  producer.  The Company  owns a 12% working  interest in
Block 343 and an 11.26% working interest in Block 363.

July,  1997.  Three  wells  are  currently  producing  about 1.5 MMcf and 33 Bbl
condensate per day net to the Company.  An exploration well to target a separate
structure  on the block is being  considered  for drilling in the second half of
1997. The Company owns a 17.5% working interest in this block, which is operated
by The Houston Exploration Company ("Houston Exploration").

         Ship Shoal Block 251. This block is located 54 miles offshore Louisiana
in 160 feet of water. Production commenced from this field on February 13, 1995.
In  September  1996  production  ceased  from the second of two wells.  No other
production  opportunities  exist on this tract so the wells will be plugged  and
the  platform  removed in the summer of 1997.  The  Company  owns a 25%  working
interest in this block which is operated by Union Pacific  Resources  Group Inc.
("UPRC").

         South Timbalier Blocks 290/291.  The South Timbalier Block 290 Field is
located 60 miles offshore in 395 feet of water. The prospect area is part of the
four-block  complex  comprised of South Timbalier  Blocks 290/291 and Ewing Bank
Blocks 782/783. The Company acquired its interest in all four blocks in the 1996
Gulf of Mexico Central Area Lease Sale. The discovery well,  South Timbalier 290
#1, was drilled  directionally  from a surface location on South Timbalier Block
291 to a bottom hole  location on Block 290.  This well,  based on wireline  log
analysis,  encountered over 150 feet of net true vertical  thickness oil and gas
pay. The well was temporarily abandoned in November 1996 pending completion once
the  production  platform is in place.  The Company and partners  are  currently
evaluating several development scenarios for this field.  Tentative plans are to
set a drilling and  production  platform  capable of handling  5,000 BOPD and 50
MMCFGPD.  The Company  operates this  four-block  complex and owns a 40% working
interest.

         Vermilion Block 203. This block is located 56 miles offshore  Louisiana
in 100 feet of water.  Five wells have been drilled and  completed on the block.
First  production  from  this  block  was  achieved  on  February  19,  1996 and
production  is now  approximately  6.0 MMcf of gas per day net to the  Company's
interest.  The  Company  owns a 50% working  interest  in this  block,  which is
operated by Houston Exploration.

1996 EXPLORATION ACTIVITY

         In 1996 the Company  participated  in the  drilling  of 21  exploration
wells,  all in the OCS of the  Gulf  of  Mexico.  Eleven  of the 21  wells  were
successful in finding  commercial  quantities of  hydrocarbons  and have been or
will be completed for production.

         On  the   four-block   area  which   comprises   East  Cameron   Blocks
349/350/355/356, the Company participated in a successful exploration well, East
Cameron  356 #1, in May 1995.  A well  targeting  a separate  structure  on East
Cameron Block 356 was spud on December 25, 1995 but was plugged and abandoned in
February 1996 after  encountering a low gas saturated sand. A third  exploration
well,  East Cameron 350 #1, was spud on January 23, 1996.  Based on wireline log
analysis,  this well  encountered  a total of 270 net feet of oil and gas pay in
four sands. The Company has a 37.5% working  interest in all four blocks,  which
are operated by Enserch.

         On South Timbalier  Block 249 an exploration  well was spud in December
1995.  Despite  promising shows in South Timbalier 249 #1, a sidetrack found the
target sands wet. The Company operated this well and owns a 50% working interest
in this block.

         An exploration well to test certain deeper sands on Vermilion Block 203
was spud on  November  28,  1995.  The  Vermilion  203 A-2 well  encountered  no
reservoir sands below 15,000 feet and has been temporarily  abandoned.  In April
1996,  an  exploration  well  to  test  certain  shallow  sands  on  this  block
encountered  over  100  feet of net gas  pay.  The  Vermilion  203 A-5  well was
completed and brought on production in May 1996.  The Company owns a 50% working
interest in this block, which is operated by Houston Exploration.

         In January 1996, an exploration  well was spud on Ship Shoal Block 251.
This well was plugged and abandoned in February. The Company owns a 25% interest
in Ship Shoal Block 251, which is operated by UPRC.

         In January,  an  exploration  well was drilled on Ship Shoal Block 261.
After  encountering  the target sands non-  hydrocarbon  bearing,  this well was
plugged back and  sidetracked  to a location  higher on the geologic  structure.
This well encountered 76 feet of net gas pay in a single sand body. A production
platform is scheduled for  installation  in early April 1997. At this time,  the
well will be  completed  and is expected  to begin  producing  in May 1997.  The
Company owns a 50% working interest in and operates this development.

         In April 1996, the Company  participated in an exploration well on Main

adjacent to the existing  producing field. This well was completed and commenced
production in May 1996. The Company owns a 15.3% working interest in this Walter
Oil operated well.

         In July 1996, the Company  participated  in a discovery on West Cameron
Block  263.  This  well  encountered  51 feet of net gas pay in a  single  sand.
Installation of a production facility is scheduled for the third quarter 1997. A
second  exploration  well targeting a separate  geologic  feature was drilled in
August 1996. This well was plugged and abandoned. The Company is the operator of
West Cameron Block 263 and owns a 50% working interest.

         In July the Company participated in an exploration well on Brazos Block
377.  Although this well  discovered  hydrocarbons,  the Company  elected not to
participate in the completion. The Company owns a 33% working interest in Brazos
Block 377.

         The Company  participated  in three  exploration  wells on East Cameron

         The  information  contained  in  the  foregoing  table  should  not  be
considered indicative of future drilling  performance,  nor should it be assumed
that there is any necessary  correlation  between the number of productive wells
drilled and the amount of oil and gas that may  ultimately  be  recovered by the
Company.  From 1994 through 1996, the Company has drilled and completed 29 gross
(8.01 net) productive wells.

         The  Company  owns no  drilling  rigs.  All of the  Company's  drilling
activities are conducted by independent contractors on a day-rate basis or under
standard drilling contracts.

MARKETS

         General.  The  revenues  generated  from  the  Company's  oil  and  gas
operations  are highly  dependent  upon the prices of and the demand for its oil
and gas  production.  The prices  received  by the  Company  for its oil and gas
production  depend upon numerous  factors beyond the Company's  control.  Future
decreases  in the  prices of oil and gas  would  have an  adverse  effect on the
Company's proved reserves, revenues, profitability and cash flow.

         Gas Sales. The Company sells substantially all of its gas production on
the  spot  market.  Generally,  the  Company's  gas  production  is  sold  under
short-term  contracts.  Total sales of gas  accounted for 68.2% and 78.9% of the
Company's  revenues  during 1995 and 1996,  respectively.  The weighted  average
prices of the gas sold by the Company under the various  month-to-month spot gas
contracts  were  $1.70 and $2.35 per Mcf of natural  gas  during  1995 and 1996,
respectively.

         The following table lists purchasers of the Company's  natural gas that
accounted for more than 10% of total revenues for the years indicated:

         Oil Sales.  Generally,  the Company's oil production is sold to various
purchasers under short-term  arrangements at prices negotiated by third parties,
but at prices no less than such  purchasers'  posted  prices for the  respective
areas less standard deductions. Total sales of oil accounted for 30.1% and 19.3%
of the  Company's  revenues  during  1995 and 1996,  respectively.  Samedan  Oil
Corporation  purchased  oil  production  from the  Company in 1995 and 1996 that
amounted to 20% and 14%,  respectively,  of the Company's  total  revenues.  The
Company  believes  that  the loss of a  purchaser  of its oil  would  not have a
material  adverse effect on its results of operations due to the availability of
other purchasers for its oil.

COMPETITION

         The  exploration  for and  production  of oil and natural gas is highly
competitive.  In seeking to obtain desirable properties,  leases and exploration
prospects, the Company faces competition from both major and independent oil and
natural  gas  companies,  as well  as from  numerous  individuals  and  drilling
programs.  Extensive  competition  also  exists in the  market for  natural  gas
produced by the Company.  Many of these  competitors  have  financial  and other
resources  substantially  in  excess  of those  available  to the  Company  and,
accordingly,  may be better  positioned to acquire and exploit  prospects,  hire
personnel  and market  production.  In addition,  many of the  Company's  larger
competitors  may be better able to respond to factors that affect the demand for
oil and natural gas production  such as changes in worldwide oil and natural gas
prices and levels of production,  the cost and availability of alternative fuels
and the application of government regulations.

REGULATION

         Oil  and  Gas  Production.  The  Company's  oil  and  gas  exploration,
production and related operations are subject to extensive rules and regulations
promulgated by federal and state agencies. Failure to comply with such rules and
regulations can result in substantial  penalties.  The regulatory  burden on the
oil and gas industry  increases the Company's cost of doing business and affects
its profitability.  Because such rules and regulations are frequently amended or
interpreted,  the  Company  is unable to predict  the  future  cost or impact of
complying with such laws.

         All of the  Company's  offshore  oil and gas leases are  granted by the
federal  government and are administered by the Mineral  Management Service (the
"MMS").  Such leases require  compliance with detailed  federal  regulations and
orders that  regulate,  among other  matters,  drilling and  operations  and the
calculation of royalty payments to the federal  government.  Ownership interests
in these leases are generally  restricted to United States citizens and domestic
corporations.  Assignments  of these leases or interests  therein are subject to
approval by the MMS.

         The federal  authorities,  as well as many state  authorities,  require
permits  for  drilling   operations,   drilling  bonds  and  reports  concerning
operations  and  impose  other  requirements  relating  to the  exploration  and
production  of oil and gas.  Such  states  also  have  statutes  or  regulations
addressing  conservation  matters,  including  provisions for the unitization or
pooling  of oil and gas  properties,  the  establishment  of  maximum  rates  of
production  from oil and gas wells and the  regulation of spacing,  plugging and
abandonment  of  such  wells.  The  statutes  and  regulations  of  the  federal
authorities, as well as many state authorities, limit the rates at which oil and
gas can be produced from the Company's properties.

         Prior to January 1, 1993, the sale for resale of certain  categories of
natural gas  production was price  regulated  pursuant to the Natural Gas Act of
1938,  the  Natural  Gas Policy  Act of 1978 (the  "NGPA")  and the  regulations
promulgated  thereunder by the Federal Energy  Regulatory  Commission  ("FERC").
However,  under  the  Natural  Gas  Wellhead  Decontrol  Act of 1989,  all price
controls of natural gas under the NGPA were phased out  effective  as of January
1, 1993.

         Several major regulatory changes have been implemented by the FERC from
1985 to the  present  that  affect  the  economics  of natural  gas  production,
transportation  and  sales.  In  addition,  the  FERC  continues  to  promulgate
revisions  to  various  aspects  of the rules and  regulations  affecting  those
segments  of the  natural  gas  industry  that  remain  subject  to  the  FERC's
jurisdiction.  The  stated  purpose  of many of these  regulatory  changes is to
promote competition among the various sectors of the gas industry.  The ultimate
impact of the complex and overlapping  rules and regulations  issued by the FERC
since 1985 cannot be predicted.  In addition,  many aspects of these  regulatory
developments have not become final but are still pending judicial and FERC final
decisions.

         Environmental.  The Company is subject to numerous laws and regulations
governing the discharge of materials into the environment or otherwise  relating
to  environmental  protection.  These  laws  and  regulations  may  require  the
acquisition  of  a  permit  before  drilling  commences,   restrict  the  types,
quantities and concentration of various substances that can be released into the
environment  in connection  with drilling and  production  activities,  limit or
prohibit drilling activities on certain lands lying within wilderness,  wetlands
and other  protected  areas and impose  substantial  liabilities  for  pollution
resulting  from the  Company's  operations.  Moreover,  the recent  trend toward
stricter  standards in  environmental  legislation  and  regulation is likely to
continue.  For instance,  legislation has been proposed in Congress from time to
time that would reclassify  certain oil and gas production  wastes as "hazardous
wastes,"  which  reclassification  would make such  wastes  subject to much more
stringent handling, disposal and clean-up requirements. If such legislation were
to be enacted,  it could have a significant impact on the operating costs of the
Company,  as well as the oil and gas industry in general.  It is not anticipated
that the Company will be required in the near future to expend  amounts that are
material  in  relation  to its total  capital  expenditure  program by reason of
environmental  laws and  regulations,  but because such laws and regulations are
frequently  changed,  the Company is unable to predict the ultimate cost of such
compliance.

         The Oil  Pollution Act of 1990 (the "OPA") and  regulations  thereunder
impose  a  variety  of  regulations  on  "responsible  parties"  related  to the
prevention of oil spills and liability for damages resulting from such spills in
United States waters. A "responsible  party" includes the owner or operator of a

CORPDAL:61486.5  15467-00006
                                                        11
<PAGE>
facility or vessel,  or the lessee or permittee of the area in which an offshore
facility is located. The OPA assigns liability to each responsible party for oil
removal  costs and a variety  of public and  private  damages.  While  liability
limits apply in some  circumstances,  a party cannot take advantage of liability
limits if the spill was  caused by gross  negligence  or willful  misconduct  or
resulted  from  violation  of  a  federal  safety,   construction  or  operating
regulation.  If the party fails to report a spill or to  cooperate  fully in the
cleanup,  liability  limits  likewise do not apply.  Few  defenses  exist to the
liability imposed by the OPA.

         The OPA also  imposes  ongoing  requirements  on a  responsible  party,
including  proof of financial  responsibility  to cover at least some costs in a
potential  spill. On August 25, 1993, the MMS published an advance notice of its
intention to adopt a rule under the OPA that would require  owners and operators
of offshore  oil and gas  facilities  to  establish  $150  million in  financial
responsibility.  Under the  proposed  rule,  financial  responsibility  could be
established  through  insurance,  guaranty,  indemnity,  surety bond,  letter of
credit,  qualification  as a  self-insurer  or a combination  thereof.  There is
substantial  uncertainty as to whether insurance  companies or underwriters will
be willing to provide  coverage  under the OPA because the statute  provides for
direct lawsuits against insurers who provide financial  responsibility coverage,
and most insurers have strongly protested this requirement.  The financial tests
or other criteria that will be used to judge  self-insurance are also uncertain.
The Company cannot predict the final form of the financial  responsibility  rule
that will be adopted by the MMS,  but such rule has the  potential  to result in
the  imposition  of  substantial  additional  annual  costs  on the  Company  or
otherwise materially adversely affect the Company. The impact of the rule should
not be any  more  adverse  to the  Company  than it will be to  other  similarly
situated or less capitalized owners or operators in the Gulf of Mexico.

         The OPA also imposes other requirements,  such as the preparation of an
oil spill  contingency  plan.  The Company has such a plan in place.  Failure to
comply with ongoing requirements or inadequate  cooperation during a spill event
may subject a responsible party to civil or criminal enforcement actions.

         The Comprehensive  Environmental  Response,  Compensation and Liability
Act ("CERCLA"),  also known as the "Superfund" law, imposes  liability,  without
regard to fault or the legality of the original  conduct,  on certain classes of
persons who are  considered to have  contributed  to the release of a "hazardous
substance" into the environment.  These persons include the owner or operator of
the  disposal  site or sites  where the  release  occurred  and  companies  that
disposed or arranged  for the  disposal of the  hazardous  substances  and under
CERCLA such persons or companies would be subject to joint and several liability
for the costs of cleaning up the  hazardous  substances  that have been released
into the  environment and for damages to natural  resources.  It is not uncommon
for  neighboring  landowners and other third parties to file claims for personal
injury and property damage allegedly caused by the hazardous substances released
into the environment.

OPERATIONAL HAZARDS AND INSURANCE

         The  Company  maintains   insurance  of  various  types  to  cover  its
operations.  Ultimate  limits  provided  under such  liability  policies are $75
million.  In addition,  the Company maintains  operator's extra expense coverage
that provides for care, custody and control of wells drilled or completed by the
Company.  The occurrence of a significant  adverse event, the risks of which are
not fully  covered by  insurance,  could have a material  adverse  affect on the
Company's financial condition and results of operations.  Moreover, no assurance
can be given that the Company will be able to maintain adequate insurance in the
future at rates it considers reasonable.

         The executive officers of the Company are as follows:

has obtained title opinions on substantially all of its producing properties and
believes that it has  satisfactory  title to such  properties in accordance with
standards  generally  accepted  in the  oil  and  gas  industry.  The  Company's
properties  are  subject to  customary  royalty  interests,  liens  incident  to
operating agreements, liens for current taxes and other burdens that the Company

financial  condition  of the  company  for each of the  years in the  three-year
period ended December 31, 1996 should be read in conjunction  with the Company's
Consolidated  Financial  Statements and related notes thereto included elsewhere
herein.

GENERAL

         The  Company  follows  the  full-cost  method  of  accounting  for  its
investments in oil and gas properties.  The Company capitalizes all acquisition,
exploration,  and development costs incurred. Proceeds from sales of oil and gas
properties are credited to the full-cost pool.  Capitalized costs of oil and gas
properties  are amortized on an overall  unit-of-production  method using proved
oil and gas reserves as determined by  independent  petroleum  engineers.  Costs
amortized  include all capitalized costs (less  accumulated  amortization);  the
estimated  future  expenditures  (based  on  current  costs) to be  incurred  in
developing  proved  reserves;  and  estimated  dismantlement,  restoration,  and
abandonment costs. See Note 2 of Notes to Consolidated Financial Statements.

RESULTS OF OPERATIONS

         The  following  table  sets forth  certain  information  regarding  the
production volumes of, average sales prices received for, and average production
costs associated with, and depletion rate associated with the Company's sales of
oil and gas for the periods indicated.

1996 COMPARED WITH 1995

      Revenues. Total revenues increased $4.3 million (17%) to $30.3 million for
1996 from $26.0  million for 1995.  The  increase in revenues  was due to higher
average oil and gas prices in 1996, partially offset by decreases in production.
The decreases in production resulted from the natural production rate decline in
the Company's  properties  developed prior to 1996 exceeding new production from
wells brought online in 1996.

<PAGE>



      Expenses. Total expenses increased $3.0 million (14%) to $23.7 million for
1996 from $20.7  million for 1995.  An increase in  depreciation,  depletion and
amortization  ("DD&A") is the primary source for the increase in expenses.  DD&A
increased  $2.4 million  (17%) to $16.0  million for 1996 from $13.6  million in
1995 due to an increase in the depletion rate  partially  offset by the decrease
in production.  Lease  operating costs and production  taxes increased  $630,000
(20%) to $3.7 million for 1996 compared with $3.1 million for 1995 due primarily
to pipeline  transportation  fees related to the production  from Mustang Island
Block  858,   Vermilion   Block  203  and  Main  Pass  Block  262.   Changes  in
administrative costs and interest expense were insignificant.

      Net Income.  Net income increased  $1.4 million (27%) to $6.6 million  for
1996 from $5.2  million in 1995.  The  primary  reason for the  increase  in net
income was increased oil and gas prices.

1995 COMPARED WITH 1994

    Revenues. Total revenues increased $16.3 million (168%) to $26.0 million for
1995 from $9.7 million for 1994.  The increase in revenues was due  primarily to
the new production  from the Company's  interest in East Cameron Blocks 331/332,
Matagorda  Block 710 and Ship Shoal  Block 251 coupled  with higher  average oil
prices in 1995 partially offset by lower average gas prices in 1995.

   Expenses.  Total expenses increased $11.6 million (129%) to $20.7 million for
1995 from $9.1  million for 1994.  An increase in  depreciation,  depletion  and
amortization  ("DD&A") is the primary source for the increase in expenses.  DD&A
increased  $9.3  million  (215%) to $13.6  million for 1995 from $4.3 million in
1994 due to increased production coupled with an increase in the depletion rate.
Interest  expense  increased  $1.4 million  (124%) to $2.5 million for 1995 from
$1.1  million for 1994  because of an increase in average  outstanding  debt and
higher average  interest  rates.  Lease  operating  costs and  production  taxes
increased $827,000 (36%) to $3.1 million for 1995 compared with $2.3 million for
1994.  Lease  operating  expenses  increased  because of  increased  production.
Reflected in the 1994 lease operating expense amount are expenses related to the
Texas Panhandle properties that were sold in August 1994.  Production costs on a
per unit basis  decreased  significantly  because East Cameron  Blocks  331/332,
Matagorda  Block 710 and Ship Shoal Block 251 all have a low per unit  operating
cost,  while the Texas  Panhandle  properties sold in August 1994 had a high per
unit operating cost.  Administrative  expenses  increased $177,000 (13%) to $1.5
million in 1995 from $1.3  million in 1994  principally  due to an  increase  in
legal,  salary and printing  expenses  partially  offset by  increased  overhead
capitalization relating to technical staff associated with exploration activity.

     Net Income.  Net income  increased  $4.6 million (700%) to $5.2 million for
1995 from  $654,000 in 1994.  The primary  reason for the increase in net income
was the increase in production.

CAPITAL RESOURCES AND LIQUIDITY

   At December 31, 1996,  the Company had existing cash and cash  investments of
$6.4 million.  Net cash provided by operating  activities  was $27.0 million for
1996, compared with $15.8 million for 1995. The primary reason for this increase
in cash provided by operating  activities  was higher  results of operations (or
earnings before depreciation, depletion and amortization) coupled with decreased
working capital requirements. Net cash used in investing activities for 1996 was
$49.9 million compared with $23.1 million in 1995. This increase was principally
due to expenditures for exploration and development prospects.

   Net cash provided by financing activities for 1996 was $25.8 million compared
with $8.6 million in 1995. The cash provided by financing activities during 1996
was from net borrowings under the Company's revolving credit facility.


   In general,  because  the  Company's  oil and gas  reserves  are  depleted by
production,  the success of its  business  strategy is dependent on a continuous
exploration  and  development   program.   Therefore,   the  Company's   capital
requirements  relate  primarily  to the  acquisition  of  undeveloped  leasehold
acreage and  exploration and  development  activities.  The Company is currently
pursuing a number of existing exploration  prospects and plans to participate in
Gulf of Mexico lease sales during 1997.

<PAGE>
   The Company's  operating needs and capital spending programs have been funded
by borrowing under its bank credit facilities, proceeds from public offerings of
its Common Stock and cash flow from operations.  The Company expects to continue
with an active exploration program and plans to drill ten additional exploration
wells  and  six   development   wells  in  1997.  The  Company  expects  capital
expenditures  during 1997 to total  approximately  $47 million.  At December 31,
1996,  the Company's  capital  resources  consisted  primarily of cash flow from
operations and available  borrowing  capacity  under the INCC Credit  Agreement.
Management  believes  that cash  flow  from  operations  along  with the  amount
available  under the INCC Credit  Agreement  will be  sufficient  to finance the
currently planned capital expenditures through December 1997.

   If the Company is successful in substantially all of its currently  scheduled
exploration prospects,  additional funds may be required in order to conduct the
necessary development activities.  Additionally,  if the Company is unsuccessful
in its currently scheduled exploration program, additional funds may be required
in order to continue the exploration and development program. If necessary,  the
Company may seek to raise additional capital in public or private equity or debt
markets.  No assurance  can be given that the Company will be able to raise such
capital if needed or on terms that are  favorable to the Company.  Any resulting
lack of  sufficient  capital may  require the Company to reduce its  interest in
such  properties  or to forego  developing  such  reserves  and may  require the
Company to curtail its  exploration and development  program.  In addition,  the
Company does not act as operator  with respect to a majority of its  properties.
The Company may not be able to control the exploration or development activities
or the associated costs with respect to properties operated by other parties.

   Credit  Facility.  The Company has a credit  agreement  as amended  (the INCC
Credit  Agreement)  with ING (U.S.) Capital  Corporation,  f/k/a  Internationale
Nederlanden (U.S.) Capital Corporation (INCC), Mees Pierson, N.V. (Mees Pierson)
and Credit  Lyonnais  (Credit  Lyonnais)  (together,  the bank group).  The INCC
Credit Agreement is secured by  substantially  all of the Company's  assets.  It
contains  financial  covenants  which require the Company to maintain a ratio of
current assets to current liabilities  (excluding the current portion of related
debt) of no less than 1.0 to 1.0 and a  tangible  net worth of not less than $40
million.  The Company is currently in compliance with such financial  covenants.
Prior to June 28, 1996, outstanding borrowings accrued interest at either INCC's
fluctuating  base rate or INCC's reserve  adjusted  Eurodollar rate plus 1.5% at
the Company's  option.  On June 28, 1996, the INCC Credit  Agreement was amended
(the Third  Amendment)  to decrease the  addition to the INCC  reserve  adjusted
Eurodollar  rate from 1.5% to 1.25% as long as  outstanding  borrowings are less
than 75% of the borrowing  base.  The borrowing base was also increased from $45
million to $50 million.

   On November 7, 1996 the Company  further  amended (the Fourth  Amendment) the
INCC Credit Agreement.  Under the Fourth Amendment,  Credit Lyonnais joined as a
lender under the INCC Credit  Agreement.  Also under the Fourth  Amendment,  the
original  facility under the INCC Credit  Agreement was designated as Facility A
and the maximum  amount of the facility was increased in amount from $50 million
to $75 million;  provided,  however,  that the maximum  amount  available to the
Company cannot exceed the borrowing  base of its  properties as determined  from
time to time by the lenders. The borrowing base under Facility A was reconfirmed
as of November 7, 1996 as $50 million.  The revolving period of borrowings under
Facility A was extended  from March 31, 1997 to September 30, 1997. On September
30, 1997 the borrowings outstanding under Facility A will be converted to a term
loan that  requires  quarterly  repayments  of principal  on a revised  schedule
through  March 31, 2001.  The  Company's  ability to borrow under  Facility A is
dependent upon the reserve value of its oil and gas  properties.  If the reserve
value of the Company's  borrowing  base  declines,  the amount  available to the
Company  under  Facility A will be reduced and, to the extent that the borrowing
base is less than the amount then outstanding under Facility A, the Company will
be  obligated  to repay such  excess  amount on 30-days  notice  from INCC or to
provide  additional  collateral.  INCC, Mees Pierson,  N.V., and Credit Lyonnais
have  substantial  discretion in determining  the reserve value of the borrowing
base.

   In addition,  a second facility was created under the Fourth Amendment.  This
new  standby  credit  facility,  Facility  B, is for the amount of $14  million.
Facility B provides for three  levels of  borrowings  by the Company,  two of $5
million each and one of $4 million.  There are no  restrictions on the Company's
ability to borrow the first $5 million under Facility B and the amount  borrowed
may be used for general  corporate  purposes.  The  Company's  ability to borrow
under the  further  two  levels of  borrowings  of $5  million  and $4  million,
respectively,  under Facility B is dependent upon the Company establishing total
proved reserves at certain levels and  appropriate  ratios between the Company's
outstanding  debt and the value of its proved  reserves.  The Company  must also

CORPDAL:61486.5  15467-00006

<PAGE>
submit detailed  proposals,  acceptable to its lenders,  outlining the manner in
which the second two levels of borrowings  under  Facility B will be used in the
development of the Company's oil and gas properties.  Facility B is repayable on
December 31, 1997.  The interest  margin over INCC reserve  adjusted  Eurodollar
rate for Facility B varies from 3.25% to 3.75%,  depending upon the ratio of the
amount of the outstanding  loans to the value of the Company's  proved reserves.
Under the INCC Credit Agreement,  interest is payable quarterly on any base rate
borrowings and payable on maturity of any Eurodollar borrowings or at the end of
three months if the maturity of the  Eurodollar  borrowing is in excess of three
months.

   The Company is currently  negotiating with the bank group regarding a further
amendment  to the INCC Credit  Agreement.  The Company  has  requested  that the
borrowing base under  Facility A of the INCC Credit  Agreement be increased from
$50 million to $65 million.  At the same time, the amount of Facility B would be
reduced from $14 million to $10 million and certain changes would be made to the
conditions  attaching  to  Facility B. No  assurance  can be given that the bank
group will agree to such  requests and any such  agreement  with respect to such
request  will be  subject  to the  negotiation  and  execution  of a  definitive
amendment to the INCC Credit Agreement.

   The INCC Credit  Agreement  does not permit the Company to pay or declare any
cash or property  dividends or otherwise make any  distribution  of capital.  On
Facility A the Company is  obligated  to pay a  quarterly  fee equal to 0.5% per
annum of the unused  portion of the  borrowing  base  under the  facility  and a
Letter of Credit  fee for each  Letter of Credit in the amount of 1.5% per annum
of the face  amount of such  Letter of  Credit.  On  Facility  B the  Company is
obligated to pay a drawdown fee for each $5 million  borrowed  equal to 0.3% for
the first $5  million,  1.15% for the second $5 million and 1.6% for the last $4
million.  Also,  the Company  must pay 0.5% per annum on the undrawn  portion of
Facility B.

   The Company expects to have to negotiate an extension of the revolving nature
of the credit  facility or to negotiate a new credit  facility before the end of
the year.

   The carrying value of the Company's long-term debt approximates fair value.

   The  following   table   illustrates  the  borrowing  base,  the  outstanding
borrowings  and the  available  borrowings  under the INCC Credit  Agreement  at
December 31, 1996.

</TABLE>
         The Company  believes that available  borrowings  under the INCC Credit
Agreement  combined  with cash flows from the  operations  will be sufficient to
fund its currently  anticipated  development  and exploration  expenses.  If the
Company  is  successful  in  substantially   all  of  its  currently   scheduled
exploration prospects, additional funds will be required in order to conduct the
necessary development  activities.  Any resulting lack of sufficient capital may
require  the  Company to reduce its  interest  in such  properties  or to forego
developing such reserves. In addition, the Company does not act as operator with
respect to most of its  properties.  Therefore,  the  Company may not be able to
control the  development  activities  or the  associated  costs with  respect to
properties operated by other parties.

         Net  Operating  Losses.  At  December  31,  1996,  the  Company had net
operating loss  carryforwards  for federal income tax purposes of  approximately
$48 million.  The net operating  losses will expire  principally in 2005 through
2010, if not previously  utilized.  Utilization of approximately  $26 million of
net  operating  loss is subject to  limitations  because of previous  changes in
ownership of the Company,  as defined in the Internal  Revenue Code.  Additional
net operating loss  limitations may be imposed because of subsequent  changes in
stock ownership of the Company.

CHANGES IN PRICES AND INFLATION

         The Company's revenues and the value of its oil and gas properties have

CORPDAL:61486.5  15467-00006
                                                        19
<PAGE>
been and will  continue to be  affected  by changes in oil and gas  prices.  The
Company's  ability to maintain  its  current  borrowing  capacity  and to obtain
additional  capital on attractive terms is also  substantially  dependent on oil
and gas prices. Oil and gas prices are subject to significant seasonal and other
fluctuations  that are beyond  the  Company's  ability  to  control or  predict.
Although  certain of the Company's  costs and expenses are affected by the level
of  inflation,  inflation  has not had a  significant  effect  on the  Company's
results of operations during 1994, 1995 or 1996.

         In an effort to reduce the  effects of the  volatility  of the price of
oil and gas on the  Company's  operations,  management  has  adopted a policy of
hedging oil and gas prices,  usually when such prices are at or in excess of the
prices  anticipated  in the  Company's  operating  budget,  through  the  use of
commodity  futures,  options,  forward  contracts and swap  agreements.  Hedging
transactions  are limited by the Board of Directors such that no transaction may
fix an oil and gas price for a term of more than 12  months,  and the  aggregate
oil and gas  production  covered by all  transactions  may not exceed 50% of the
Company's  budgeted  production  for any  12-month  period  from the date of the
transaction  or 75% of the Company's  budgeted  production  for any single month
from the date of the transaction. By hedging its oil and gas prices, the Company
intends to mitigate  the risk of future  declines  in oil and gas prices.  Under
certain contracts should oil or gas prices increase above the contract rate, the
Company will not participate in the higher prices for the production.

         The Company has  entered  into a number of gas price swap  transactions
under  which the  Company  receives a fixed  price per MMBtu and pays a floating
price based on the settlement  prices for the NYMEX Natural Gas futures contract
for the delivery  month.  In total under these  contracts  the Company fixed the
price of  4,065,000  MMBtu of gas for 1996 at an  average  price of  $2.018  per
MMBtu. Gas revenues were reduced $2.4 million and increased $323,000 in 1996 and
1995, respectively,  as a result of hedging transactions.  The Company has fixed
the price of  630,000  MMBtu of gas for the  period  January to March 1997 at an
average price of $3.32 per MMBtu.

         The Company may enter into certain interest rate hedging contracts.  By
hedging its interest rate under its credit facility, the Company would intend to
mitigate the risk of future  increases in interest rates.  Should interest rates
decrease below the contract rate, the Company will not  participate in the lower
interest rate for the portion of the credit facility under the hedging contract.
The Company currently has no interest rate hedging contracts in place.

                         Report of Independent Auditors

Board of Directors
Cairn Energy USA, Inc.

We have audited the  accompanying  consolidated  balance  sheets of Cairn Energy
USA,  Inc.  (the  Company),  as of December  31, 1995 and 1996,  and the related
consolidated statements of operations,  stockholders' equity, and cash flows for
each of the three years in the period ended December 31, 1996.  These  financial
statements   are  the   responsibility   of  the   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 consolidated  financial statements referred to above present
fairly, in all material respects,  the consolidated  financial position of Cairn
Energy USA, Inc., at December 31, 1995 and 1996, and the consolidated results of
its  operations  and its cash  flows for each of the three  years in the  period
ended  December 31, 1996,  in  conformity  with  generally  accepted  accounting
principles.

1. SIGNIFICANT ACCOUNTING AND REPORTING POLICIES

Principles of Consolidation and Basis of Financial Statement Presentation

The consolidated  financial statements include the accounts of Cairn Energy USA,
Inc. (the Company) and its wholly owned  subsidiary.  All intercompany  accounts
and transactions have been eliminated in consolidation.

The preparation of 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 reported amounts of revenues and expenses during the reporting period.
Actual results could differ from these estimates.

The Company is engaged in the exploration for and production of oil and gas.

Property and Equipment

The Company  follows the full-cost  method of accounting for its  investments in
oil and gas properties.  The Company capitalizes all direct and certain indirect
costs associated with acquisition, exploration, and development costs of oil and
gas  properties.  Proceeds from sales of oil and gas  properties are credited to
the  full-cost  pool.  Capitalized  costs of proved oil and gas  properties  are
amortized  on a  unit-of-production  method using proved oil and gas reserves as
determined by  independent  petroleum  engineers.  Costs  amortized  include all
capitalized  costs  (less  accumulated   amortization);   the  estimated  future
expenditures  (based on  current  costs) to be  incurred  in  developing  proved
reserves;  and estimated  dismantlement,  restoration,  and  abandonment  costs.
Estimated future abandonment,  dismantlement, and site restoration costs include
costs to dismantle,  relocate,  and dispose of the Company's offshore production
platforms,  gathering systems, wells, and related structures. Such costs related
to onshore  properties,  net of estimated salvage values, are not expected to be
significant.

The Company capitalized  approximately $866,000,  $1,200,000,  and $1,500,000 of
internal  costs  during the years  ended  December  31,  1994,  1995,  and 1996,
respectively.  Such  capitalized  costs include salaries and related benefits of
individuals  directly involved in the Company's  acquisition,  exploration,  and
development  activities,  based on a  percentage  of their time  devoted to such
activities.

Under rules of the Securities and Exchange  Commission ("SEC") for the full-cost
method  of  accounting,  the net  carrying  value of oil and gas  properties  is
limited to the sum of the present value (10% discount rate) of estimated  future
net cash flows from proved reserves,  based on period-end prices and costs, plus
the lower of cost or estimated fair value of unproved properties.

1. SIGNIFICANT ACCOUNTING AND REPORTING POLICIES (CONTINUED)

Furniture and equipment are  depreciated on a  straight-line  basis based on the
estimated useful lives of the respective assets.

Cash and Cash Equivalents

Cash and cash equivalents include certificates of deposit or other highly liquid
investments with maturities of three months or less when purchased.

Deferred Charges

Deferred  charges include prepaid pipeline charges that are recognized on a unit
of throughput basis, and loan costs that are amortized on a straight-line  basis
over the terms of the respective loans.

Concentrations of Credit Risk

The  Company  operates  exclusively  in the oil and gas  industry  in the United
States.  Accounts  receivable  terms are generally for 30 days. The Company does
not  require  collateral.  Management  periodically  performs  reviews as to the
creditworthiness  of  their  customers.   The  Company  has  not  sustained  any
significant credit losses on sales of oil and gas.

Gas Imbalances

The Company  follows the sales method of accounting  for gas  imbalances,  which
recognizes  over and under lifts of gas when sold, to the extent  sufficient gas
reserves  or  balancing   agreements   are  in  place.   Gas  revenues  are  not
significantly different from the Company's share of production.

Oil and Gas Hedging Activities

In an effort to reduce the effects of the volatility of the price of oil and gas
on the Company's operations,  management has adopted a policy of hedging oil and
gas prices  whenever such prices are in excess of the prices  anticipated in the
Company's  operating  budget and profit plan through the use of  commodity  swap
agreements  with major  financial  institutions.  These  agreements  involve the
receipt of fixed priced amounts in exchange for variable payments based on NYMEX
prices and specific volumes. The

differential  to be paid or  received  is  recorded  in the month of the related
production  and  recognized  as a  component  of oil and gas  revenues.  Hedging
transactions are limited by the Board of Directors to 50% of budgeted production
for the succeeding 12 months and no more than 75% of budgeted  production in any
one month. The Company does not hold or issue financial  instruments for trading
purposes.

Stock Options

The Company has elected to follow  Accounting  Principles  Board Opinion No. 25,
"Accounting  for  Stock  Issued to  Employees"  (APB 25) in  accounting  for its
employee  stock  options.  Under APB 25, if the exercise  price of an employee's
stock option equals or exceeds the market price of the  underlying  stock on the
date of grant, no compensation expense is recognized.

Earnings (Loss) Per Common Share

Earnings  (loss) per common share data is computed  using the  weighted  average
number of common shares and dilutive common equivalent shares outstanding. Fully
diluted  earnings  per share data is not  presented  because it would not differ
from the amounts shown.

2. ACQUISITION OF OIL AND GAS ASSETS OF SMITH OFFSHORE EXPLORATION II

On October 10, 1994, the Company purchased  substantially all of the oil and gas
assets  (the  Assets)  of Smith  Offshore  Exploration  II (Smith)  from  Phemus
Corporation  (Phemus),  a  subsidiary  of the  President  and Fellows of Harvard
College and sole  stockholder of Smith, in exchange for 4,500,000  shares of the
Company's  common  stock,  subject to  adjustment  pursuant  to the terms of the
Agreement,  and the  assumption  of  certain  liabilities  related  to the Smith
Assets.  The acquisition gave the Company  interests in 22 additional  blocks in
the Outer Continental Shelf of the Gulf of Mexico.  The Agreement  provided that
1,000,000  of the shares  issued be placed in escrow (the Escrow  Shares) at the
closing and, thereafter, the Escrow Shares and certain warrants to acquire up to
a  maximum  of  800,000  shares  of  Common  Stock  would be issued to Phemus or
returned  to  the  Company  based  on  a  valuation  of  oil  and  gas  reserves
attributable  to the Assets at a date to be selected prior to June 30, 1995, but
could be extended under certain  circumstances  until December 31, 1995. If such
valuation was less than  $26,250,000,  Smith and Phemus,  jointly and severally,
would be obligated to pay the Company the amount by which  $26,250,000  exceeded
the valuation,  up to a maximum of $3,900,000.  The acquisition of Smith did not
have a material effect on the results of operations of the Company for 1994.

On the basis of a valuation  of the Smith  properties  as of June 30,  1995,  by
independent  petroleum engineers  reflecting a range of values below the Minimum
Valuation,  Phemus and the  Company  entered  into an  agreement  regarding  the
purchase price  adjustment  under the Smith  Acquisition  Agreement  pursuant to
which Phemus  returned  the Escrow  Shares and paid $3.9 million to the Company.
The $3.9 million  payment to the Company is reflected as a reduction of the cost
of the Smith  properties.  There was no adjustment  in the  Company's  financial
statements for the return of the Escrow Shares because for financial  accounting
purposes, the Escrow Shares were never recorded as having been issued.

3. LONG-TERM DEBT

The Company has a credit  agreement as amended (the INCC Credit  Agreement) with
ING (U.S.) Capital Corporation,  f/k/a Internationale Nederlanden (U.S.) Capital
Corporation  (INCC),  Mees  Pierson,  N.V.  (Mees  Pierson) and Credit  Lyonnais
(Credit Lyonnais).  The INCC Credit Agreement is secured by substantially all of
the Company's assets. It contains financial  covenants which require the Company
to  maintain a ratio of current  assets to current  liabilities  (excluding  the
current  portion of related  debt) of no less than 1.0 to 1.0 and a tangible net
worth of not less than $40 million.  The Company is currently in compliance with
such financial covenants. Prior to June 28, 1996, outstanding borrowings accrued
interest  at either  INCC's  fluctuating  base rate or INCC's  reserve  adjusted
Eurodollar  rate plus 1.5% at the Company's  option.  On June 28, 1996, the INCC
Credit  Agreement was amended (the Third  Amendment) to decrease the addition to
the  INC  reserve  adjusted  Eurodollar  rate  from  1.5%  to  1.25%  as long as
outstanding  borrowings  are less than 75% of the borrowing  base. The borrowing
base was also increased from $45 million to $50 million.

On November 7, 1996, the Company further amended (the Fourth Amendment) the INCC
Credit Agreement. Under the Fourth Amendment, Credit Lyonnais joined as a lender
under the INCC Credit Agreement.  Also under the Fourth Amendment,  the original
facility  under the INCC Credit  Agreement was  designated as Facility A and the
maximum  amount of the facility was  increased in amount from $50 million to $75
million;  provided,  however,  that the maximum amount  available to the Company
cannot exceed the borrowing  base of its  properties as determined  from time to
time by the lenders.  The borrowing base under Facility A was  reconfirmed as of
November 7, 1996,  as $50 million.  The  revolving  period of  borrowings  under
Facility A was extended  from March 31, 1997 to September 30, 1997. On September
30, 1997,  the  borrowings  outstanding  under Facility A will be converted to a
term loan that requires quarterly  repayments of principal on a revised schedule
through  March 31, 2001.  The  Company's  ability to borrow under  Facility A is
dependent upon the reserve value of its oil and gas  properties.  If the reserve
value of the Company's  borrowing  base  declines,  the amount  available to the
Company  under  Facility A will be reduced and, to the extent that the borrowing
base is less than the amount then outstanding under Facility A, the Company will
be  obligated  to repay such  excess  amount on 30-days  notice  from INCC or to
provide  additional  collateral.  INCC, Mees Pierson,  N.V., and Credit Lyonnais
have  substantial  discretion in determining  the reserve value of the borrowing
base. At December 31, 1995 and 1996, the Company had  outstanding  borrowings of
$15.5 million and $42.0 million, respectively, under this facility.

In addition, a second facility was created under the Fourth Amendment.  This new
standby credit facility,  Facility B, is for the amount of $14 million. Facility
B provides for three levels of borrowings by the Company, two of $5 million each
and one of $4 million.  There are no  restrictions  on the Company's  ability to
borrow the first $5 million under Facility B and the amount borrowed may be used
for  general  corporate  purposes.  The  Company's  ability to borrow  under the
further two levels of  borrowings  of $5 million  and $4 million,  respectively,
under  Facility  B is  dependent  upon the  Company  establishing  total  proved
reserves  at  certain  levels  and  appropriate  ratios  between  the  Company's
outstanding  debt and the value of its proved  reserves.  The Company  must also
submit detailed  proposals,  acceptable to its lenders,  outlining the manner in
which the second two levels of borrowings  under  Facility B will be used in the
development of the Company's oil and gas properties.  Facility B is repayable on
December 31, 1997.  The interest  margin over INCC reserve  adjusted  Eurodollar
rate for Facility B varies from 3.25% to 3.75%,  depending upon the ratio of the
amount of the outstanding loans to

the value of the Company's  proved  reserves.  Under the INCC Credit  Agreement,
interest  is  payable  quarterly  on any base rate  borrowings  and  payable  on
maturity  of any  Eurodollar  borrowings  or at the end of three  months  if the
maturity of the Eurodollar  borrowing is in excess of three months.  At December
31, 1995 and 1996, there were no borrowings under Facility B.

The INCC Credit Agreement does not permit the Company to pay or declare any cash
or property dividends or otherwise make any distribution of capital. On Facility
A, the Company is  obligated  to pay a quarterly  fee equal to 0.5% per annum of
the unused  portion of the  borrowing  base under the  facility  and a Letter of
Credit fee for each Letter of Credit in the amount of 1.5% per annum of the face
amount of such Letter of Credit. On Facility B the Company is obligated to pay a
drawdown  fee for  each $5  million  borrowed  equal  to 0.3%  for the  first $5
million, 1.15% for the second $5 million and 1.6% for the last $4 million. Also,
the Company must pay 0.5% per annum on the undrawn portion of Facility B.

At December 31, 1996,  the future  minimum  principal  payments on the Company's
long-term  debt  subsequent  to  December  31,  1997  were as  follows  based on
borrowings  outstanding  at December  31,  1996:  $16.8  million in 1998,  $15.1
million in 1999, $6.7 million in 2000, and $3.4 million in 2001.

The carrying value of the Company's long-term debt approximates fair value.

4. STOCKHOLDERS' EQUITY

On October 10, 1994, the Company purchased  substantially all of the oil and gas
assets of Smith in exchange for 4,500,000  shares of the Company's common stock,
subject to adjustment  pursuant to the terms of the Agreement and the assumption
of certain liabilities (Note 2). For accounting  purposes,  the 1,000,000 Escrow
Shares were not recorded as issued as a result of the June 30, 1995 valuation.

At the time of the Smith acquisition,  the Company's then majority  shareholder,
Cairn Energy PLC, sold 2,000,000  shares of the Company's common stock to Phemus
at a price of $7.50 per share.  Cairn Energy PLC also sold  2,500,000  shares of
Company  common stock  resulting  in Cairn Energy PLC reducing its  ownership to
approximately 17.5% of the Company's common stock in 1994.

A public  offering of 1,562,500  shares of Common Stock at an offering  price of
$11.25 per share was closed on September 18, 1995. The net proceeds, aggregating
approximately $16.6 million,  were used to reduce borrowings under the Company's
credit  agreement  (Note 3). In conjunction  with this  offering,  the Company's
principal  shareholder,  Phemus,  sold 2,750,000  shares of the Company's common
stock.

In April and June 1995, Cairn Energy PLC sold its remaining  2,792,260 shares of
Company common stock.

</TABLE>

At December 31,  1996,  the Company had net  operating  loss  carryforwards  for
federal  income tax purposes of  approximately  $48 million.  The net  operating
losses will expire principally in 2005 through 2010, if not previously utilized.
Utilization of approximately $26 million of the net operating loss carryforwards
is subject to various  limitations  because of previous  changes in ownership of
the Company,  as defined in the Internal Revenue Code.  Additional net operating
loss limitations may be imposed because of subsequent changes in stock ownership
of the Company.

6. EMPLOYEE BENEFIT PLANS

The Company sponsors a plan to provide retirement  benefits under the provisions
of  Section  401(k)  of the  Internal  Revenue  Code (the  401(k)  Plan) for all
full-time  employees.  Employees  may  elect  to  contribute  up to 15% of their
compensation. The Company matches 100% of the employee's contributions, up to 5%
of the employee's compensation.  Beginning in 1995, at the end of each year, the
Company  contributes  Company common stock to each eligible  employee's  account
valued at the equivalent of 5% of each such  employee's  compensation.  Benefits
under the  401(k)  Plan are  limited  to the  assets  of the  401(k)  Plan.  The
Company's  contributions in cash to the 401(k) Plan were $98,385,  $62,678,  and
$67,663 for the years ended December 31, 1994, 1995, and 1996, respectively. The
Company's  contributions  in Company  common  stock to the  401(k)  Plan were 0,
4,864,  and 6,669 shares for the years ended December 31, 1994,  1995, and 1996,
respectively.

The Company's  Employee  Incentive Bonus Plan was adopted in 1993 and revised in
1994. The Employee Incentive Bonus Plan rewards those employees when the Company
has added proved reserves for the year in excess of its production for the year,
but only when such additional  reserves have a finding and development cost less
than $1.00 per Mcf.  Under the Employee  Incentive  Bonus Plan, the bonus cannot
exceed $250,000 in the aggregate and is allocated among the specified  employees
based upon preset  percentages except that individual bonuses can not exceed 50%
of salary.  Any bonus earned for the year vests and is paid out to the employees
in three equal annual  installments,  subject to continued  employment  with the
Company.  Based on reserve  additions,  the  Company's  employees  were  awarded
bonuses in the aggregate amount of $242,028 for the year ended December 31, 1994
under the Employee Incentive Bonus Plan. Such bonuses are being accrued over the
respective vesting periods. No incentive bonuses were awarded in 1995 or 1996.

In May 1993, the Company's  stockholders ratified the adoption of the 1993 Stock
Option Plan and the 1993  Directors'  Stock Option  Plan.  The 1993 Stock Option
Plan authorizes the granting of incentive stock options and  nonstatutory  stock
options to key  employees,  including  executive  officers and  directors of the
Company. The Company's  Compensation Committee administers the 1993 Stock Option
Plan.  Options granted under the 1993 Stock Option Plan may be either  incentive
stock options or nonstatutory stock options,  as determined in the discretion of
the Compensation Committee.  The exercise price per share for an option shall be
any price determined by the Compensation Committee;  provided, however, that the
exercise  price per share of incentive  stock options shall not be less than the
fair  market  value of the Common  Stock on the date of the grant of the option.
Each option is exercisable in such amounts, at such intervals, and on such terms
as the Compensation  Committee  determines in its sole discretion.  However,  no
option shall be exercisable  during the six-month  period  following the date of
its grant,  and no option shall be exercisable more than 10 years after the date
of its grant. The Company's  stockholders  approved an increase in the number of
shares  reserved  for  issuance  under the 1993 Stock  Option Plan from  400,000
shares to 650,000 shares in May 1995 and another increase from 650,000 shares to
1,150,000  shares in May 1996.  Also in May 1996, the  stockholders  approved an
amendment to the 1993 Stock Option Plan that  provides  that all options held by
an  employee  granted  under the 1993 Stock  Option Plan will vest upon death of
such  employee  and provides  that the exercise  period for such options will be
twenty-four months following death or termination of an employee.

6. EMPLOYEE BENEFIT PLANS (CONTINUED)

The 1993  Directors'  Stock Option Plan  authorizes the granting of nonstatutory
stock  options  to  directors  of the  Company  who are not and  have  not  been
employees of the Company or any affiliated  corporations except Cairn Energy PLC
(a Nonemployee  Director).  On the date a Nonemployee  Director begins each term
that he serves as a member of the Board of Directors,  such Nonemployee Director
will automatically  receive an option to purchase 10,000 shares of Common Stock.
The exercise  price per share for an option  granted  under the 1993  Directors'
Stock Option Plan shall be the fair market value of the Common Stock on the date
of the grant.  Each option is fully exercisable six months after the date of its
grant.  However,  no option may be exercised more than five years after the date
of its grant.  In May 1996, the Company's  stockholders  approved an increase in
the number of shares  reserved  for  issuance  under the 1993  Directors'  Stock
Option Plan from 150,000 shares to 270,000 shares.

</TABLE>

Statement of Financial Accounting Standards No. 123, "Accounting for Stock Based
Compensation,"  (SFAS 123)  requires the  disclosure of pro forma net income and
earnings per share information  computed as if the Company had accounted for its
employee stock options granted  subsequent to December 31, 1994,  under the fair
value  method  set forth in SFAS 123.  The fair  value  for  these  options  was
estimated at the date of grant using a  Black-Scholes  option pricing model with
the following  weighted-average  assumptions for 1995 and 1996, respectively:  a
risk-free interest rate of 5.9%, a dividend yield of 0%, and a volatility factor
of 38.3%.  The fair value of these  options was  estimated  based on an expected
life of one year from the vesting date.

The Black-Scholes option valuation model was developed for use in estimating the
fair value of traded  options which have no vesting  restrictions  and are fully
transferable.  In addition,  option valuation models require the input of highly
subjective  assumptions  including the expected stock price volatility.  Because
the  Company's  employee  stock  options  have   characteristics   significantly
different from those of traded  options,  and because  changes in the subjective
input assumptions can materially affect the fair value estimate, in management's
opinion,  the  existing  models do not  necessarily  provide a  reliable  single
measure of the fair value of its employee  stock options.  In addition,  because
SFAS 123 is applicable only to options granted  subsequent to December 31, 1994,
the pro forma  information does not reflect the pro forma effect of all previous
stock option grants of the Company.

For purposes of pro forma  disclosures,  the estimated fair value of the options
is amortized to expense over the options'  vesting  period.  The  Company's  pro
forma   information   follows  (in  thousands  except  for  earnings  per  share
information):

7. OIL AND GAS HEDGING ACTIVITIES AND COMMITMENTS

While the use of hedging  arrangements limits the downside risk of adverse price
movements, it may also limit future gains from favorable movements.  All hedging
is accomplished pursuant to exchange-traded  contracts or master swap agreements
based upon  standard  forms.  The Company  addresses  market  risk by  selecting
instruments  whose value  fluctuations  correlate  strongly with the  underlying
commodity  being  hedged.  Credit risk related to hedging  activities,  which is
minimal,  is managed by requiring  minimum credit standards for  counterparties,
periodic  settlements,  and  mark to  market  valuations.  The  Company  has not
historically  been  required to provide  any  significant  amount of  collateral
relating to its hedging activities.

At December 31, 1996,  the Company had entered into various swap  agreements  to
fix selling  prices for 630,000  MMBtus of natural  gas during  January  through
March 1997 at a weighted  average  NYMEX  price of $3.32 per MMBtu.  While these
contracts have no carrying  value,  their fair value (the estimated  amount that
would  have  been  received  by the  Company  upon  termination  of the swaps at
December 31, 1996) was approximately $198,000.

During the years ended  December 31, 1994,  1995, and 1996, oil and gas revenues
were  reduced by  $54,000,  increased  by  $323,000  and  reduced by  $2,449,000
respectively, as a result of hedging transactions.

8. LEGAL PROCEEDINGS AND CLAIMS

The Company is subject to certain legal proceedings and claims that arise in the
ordinary  conduct of its business.  In the opinion of management,  the amount of
ultimate liability,  if any, with respect to these actions,  will not materially
affect the  consolidated  financial  condition or results of  operations  of the
Company.

9. OPERATIONS

Nature of Operations

The Company, explores for, develops and produces oil and gas, principally in the
shallow waters of the Outer Continental Shelf ("OCS") of the Gulf of Mexico. The
Company's  strategy is to expand its  reserve  base and  production  principally
through exploration and associated development drilling.

9. OPERATIONS (CONTINUED)

The Company's principal  producing  properties are located in the Gulf of Mexico
and consist of East Cameron Blocks 331/332, which began production in the fourth
quarter  of 1994,  Matagorda  Block 710,  which  began  production  in the first
quarter  of 1995,  Galveston  343/363  Field  which  began  production  in 1990,
Vermilion Block 203 and Main Pass Block 262, which began production in the first
quarter of 1996 and Mustang Island Block 858 which began production in the third
quarter of 1996.  Revenues  from these six  properties  comprised  approximately
74.1% of the Company's total revenues for the year ended December 31, 1996.

</TABLE>

The unproven  properties  are excluded  from the  amortization  base and consist
primarily of acreage acquisition costs, related geological and geophysical costs
and exploration drilling costs in progress or awaiting evaluation.  The majority
of these costs are expected to be evaluated  during the Company's  1997 and 1998
drilling programs.

10. SUPPLEMENTARY INFORMATION (CONTINUED)

Reserve Quantity Information (Unaudited)

All of the Company's  reserves are located in the continental United States. The
Company's  proved  reserves at December  31, 1995 and 1996 were  prepared by the
Company  and  reviewed  by  Ryder  Scott  Company,   an  independent   petroleum
engineering firm.

Proved reserves (developed and undeveloped) are estimated  quantities of oil and
gas that geological and engineering data  demonstrate with reasonable  certainty
to be recoverable in future years from known  reservoirs  under current economic
and operating conditions.  The estimation of reserves is an interpretive process
that is  subject  to  continuing  revision  as  additional  information  becomes
available.

The Company's  proved  developed  reserves are  categorized as such based on the
availability of current production data, open-hole and cased-hole logs analyses,
and other productivity indications.

The  estimation  of proved  undeveloped  reserves  was limited to direct  offset
locations to existing wellbores and to geological  formations that have shown to
be productive in the area.

Reserve  estimates  are  imprecise  and may be expected to change as  additional
information becomes available.  Furthermore,  estimates of oil and gas reserves,
of  necessity,  are  projections  based  on  engineering  data,  and  there  are
uncertainties  inherent  in the  interpretation  of  such  data  as  well as the
projection  of  future  rates  of  production  and  the  timing  of  development
expenditures.   Reserve  engineering  is  a  subjective  process  of  estimating
underground  accumulations  of oil and gas that  cannot be  measured in an exact
way,  and the  accuracy of any reserve  estimate is a function of the quality of
available data and of engineering  and geological  interpretation  and judgment.
Accordingly,  there can be no assurance  that the reserves set forth herein will
ultimately  be produced nor can there be assurance  that the proved  undeveloped
reserves  will  be  developed  within  the  periods  anticipated.   The  Company
emphasizes  with  respect to the  estimates  prepared by  independent  petroleum
engineers that the discounted future net cash inflows should not be construed as
representative  of the fair  market  value of the proved oil and gas  properties
belonging to the  Company,  since  discounted  future net cash inflows are based
upon  projected  cash  inflows  which do not  provide for changes in oil and gas
prices nor for escalation of expenses and capital costs. The  meaningfulness  of
such  estimates is highly  dependent upon the accuracy of the  assumptions  upon
which they are based.

The Company's principal developed  properties are located in the Gulf of Mexico,
and are East Cameron Blocks  331/332,  Vermilion Block 203, Main Pass Block 262,
Mustang Island Block 858,  Matagorda Block 710, and Galveston  343/363 Field. As
of December 31, 1995 and 1996, the Company's net interest in the proved reserves
of these properties was approximately 61.2 Bcfe and 63.9 Bcfe, respectively.
The Company's capital  expenditures for 1997 are anticipated to be approximately
$47 million.

Standardized  Measure  of  Discounted  Future  Net  Cash  Flows  from  Estimated
Production of Proved Oil and Gas Reserves After Income Taxes (Unaudited)

In the opinion of the Company's management,  no major discovery or adverse event
has occurred since December 31, 1996,  that would cause a significant  change in
proved reserve quantities as estimated at December 31, 1996.  Reserves cannot be
measured exactly because reserve estimates  involve  subjective  judgments.  The
estimates  must be reviewed  periodically  and  adjusted  to reflect  additional
information  gained from reservoir  performance,  new geological and geophysical
data, and economic changes.  The values expressed are estimates only and may not
reflect  realizable  values or fair market values of the oil and gas  ultimately
extracted and  recovered.  The estimated  future net revenues may not accurately
reflect  proceeds  of  production  to be received in the future from the sale of
crude oil,  condensate,  and natural gas currently  owned.  The present value of
estimated future net revenues does not necessarily reflect the actual costs that
would be incurred to acquire equivalent oil and gas reserves.

The following table sets forth a standardized  measure of the discounted  future
net cash flows attributable to the Company's proved oil and gas reserves. Future
cash  inflows  were  computed  by  applying  year-end  oil and gas prices to the
estimated  future  production  of proved  reserves.  The future  production  and
development costs represent the estimated future  expenditures (based on current
costs) to be incurred in developing and producing the proved reserves,  assuming
continuation of existing economic  conditions.  The timing of future development
costs is based on management's evaluation of the Company's projected

cash flows and financing resources.  Future income tax expenses were computed by
applying  statutory  income tax rates to the difference  between pretax net cash
flows relating to the Company's proved oil and gas reserves and the tax basis of
proved oil and gas properties and available net operating loss carryforwards and
statutory depletion,  reduced by investment tax credits.  Discounting the annual
net cash  inflows at 10%  illustrates  the impact of timing on these future cash
inflows.

                                    GLOSSARY

         The terms  defined in this  glossary  are used  throughout  this annual
report.

         2-D SEISMIC.  The method by which an image of the earth's subsurface is
created through the interpretation of collected seismic data.

         3-D  SEISMIC.  The  method  by which a three  dimensional  image of the
earth's  subsurface is created through the  interpretation  of collected seismic
data. 3-D surveys allow for a more detailed understanding of the subsurface than
do  conventional  surveys  and  contribute  significantly  to  field  appraisal,
development and production.

         AVO ANALYSIS.  A geophysical  technique that when applied under certain
conditions  allows  interpreters  to  distinguish  gas bearing  sands from other
bright spot causes such as hard streaks, wet sands and lignite.

         BBL.  One stock tank barrel, or 42 U.S. gallons liquid volume, used 
herein in reference to crude oil or other liquid hydrocarbons.

         BCF.  One billion cubic feet.

         BCFE.  One  billion cubic  feet  of  natural  gas  equivalents  using a
conversion  rate of six  thousand  cubic feet of natural  gas for each barrel of
oil.

         DEVELOPED ACREAGE.  The  number   of  acres   which  are  allocated  or
assignable to producing wells or wells capable of production.

         DEVELOPMENT WELL.  A  well drilled  within the proved area of an oil or
gas reservoir to the depth of a stratigraphic horizon known to be productive.

         DISCOUNTED  PRESENT VALUE. A method of determining the present value of
proved  reserves.  Under the SEC method,  the future net revenues  before income
taxes from  proved  reserves  are  estimated  assuming  that oil and natural gas
prices and production costs remain constant. The resulting stream of revenues is
then discounted at the rate of 10% per year to obtain the present value.

         DRY WELL.  A well found to be incapable of producing either oil or  gas
in sufficient quantities to justify completion as an oil or gas well.

         EXPLORATORY  WELL.  A well drilled to find and produce oil or gas in an
unproved  area,  to find a new  reservoir  in a  field  previously  found  to be
productive of oil or gas in another reservoir, or to extend a known reservoir.

         FARM-OUT/FARM-IN. An agreement pursuant to which the owner of a working
interest  in an oil and gas lease  delivers  the  contractual  right to earn the
working  interest or a portion  thereof to another party who desires to drill on
the leased  acreage.  Generally,  the  assignee is required to drill one or more
wells in order to earn a working  interest in the acreage.  The assignor usually
retains a royalty or a working interest in the lease after payout.  The assignor
is  said  to  have  "farmed-out"  the  acreage.  The  assignee  is  said to have
"farmed-in" the acreage.

         FINDING COSTS. Expressed in dollars per MCFE, is calculated by dividing
the amount of total capital  expenditures  by the amount of total reserves added
during  the  same   period  as  a  result  of  drilling   activities,   property
acquisitions, reserve revisions and improved recovery.

         GROSS ACRES OR GROSS WELLS.  The total acres or wells, as  the case may
be, in which a working interest is owned.

         MBBL. One thousand barrels of crude oil or other liquid hydrocarbons.

         MCF.  One thousand cubic feet.

capable of production.

         PROVED DEVELOPED RESERVES.    Reserves  that  can  be  expected  to  be
recovered through existing wells with existing equipment and operating methods.

         PROVED RESERVES. The estimated quantities of crude oil, natural gas and
natural gas liquids which  geological  and  engineering  data  demonstrate  with
reasonable  certainty to be  recoverable  in future years from known  reservoirs
under existing economic and operating conditions.

         PROVED UNDEVELOPED RESERVES. Reserves that are expected to be recovered
from new wells on undrilled  acreage,  or from existing wells where a relatively
major expenditure is required for recompletion.

         ROYALTY INTEREST.  An interest in an oil and gas property entitling the
owner to a share of oil and gas production free of costs of production.

         UNDEVELOPED ACREAGE. Lease acreage on which wells have not been drilled
or  completed  to a  point  that  would  permit  the  production  of  commercial
quantities  of oil and gas  regardless of whether such acreage  contains  proved
reserves.

         WORKING  INTEREST.  The  operating  interest  which gives the owner the
right to drill,  produce and conduct operating  activities on the property and a
share of production,  subject to all royalties,  overriding  royalties and other
burdens and to all costs of  exploration,  development  and  operations  and all
risks in connection therewith.

place:

                  "6.4. TERM, TIME OF EXERCISE AND  TRANSFERABILITY  OF OPTIONS.
         In addition to such other terms and  conditions as may be included in a
         particular Agreement granting an Option, an Option shall be exercisable
         during  a  Holder's  lifetime  only by the  Holder  or by the  Holder's
         guardian or legal representative.

                  An Option shall not be transferrable other than by will or the
         laws of descent and  distribution  or pursuant to a qualified  domestic
         relations  order as  defined  by the  Code or  Title I of the  Employee
         Retirement Income Security Act or the rules thereunder.

                  The provisions of the remainder of this Paragraph  shall apply
         to  the  extent  a  Holder's   Agreement  does  not  expressly  provide
         otherwise.  If a  Holder  ceases  to be  an  Eligible  Individual,  the
         portion,  if  any,  of the  Option  that  is  exercisable  but  remains
         unexercised  on the date the Holder stops being an Eligible  Individual
         shall  terminate  ninety  (90) days after such  Holder  ceases to be an
         Eligible Individual.  Notwithstanding the foregoing, if a Holder ceases
         to be an Eligible Individual by reason of (a) disability (as defined in
         section  105(d)(4) of the Code immediately  prior to its repeal) or (b)
         death, the Holder shall have the right for twelve months after the date
         of  disability or death to exercise an Option to the extent such Option
         is exercisable on the date of his disability or death.

                  The portion of the Option that is not  exercisable on the date
         the Holder ceases to be an Eligible  Individual  shall terminate and be
         forfeited  to  the   Corporation   on  the  date  of  such   cessation.
         Notwithstanding  the previous  sentence,  if a Change in Control of the
         Corporation  occurs and, within twenty-four months from the date of the
         Change in Control of the Corporation, a Holder ceases to be an Eligible
         Individual  either because (i) the Corporation  terminates the Holder's
         employment  with the  Corporation  for a reason other than Due Cause or
         (ii) the Holder terminates his employment with the Corporation due to a
         Severance   Termination  by  the  Holder  of  the  Holder's  Employment
         Agreement, then any Options held by such Holder shall be exercisable in
         full on the date such Holder ceases to be an Eligible Individual and no
         portion of an Option held by such Holder shall  terminate or forfeit on
         the date such holder ceases to be an Eligible Person.

                  Notwithstanding  any other  provision of this Plan,  no Option
         shall be  exercisable  after the  expiration of ten (10) years from the
         date  it is  granted,  or the  period  specified  in  PARAGRAPH  4.1 if
         applicable.

                  The  Committee  shall have the  authority  to prescribe in any
         Agreement  that the Option  evidenced by the Agreement may be exercised
         in full or in part as to any number of shares  subject to the Option at
         any time or from time to time during the term of the Option, or in such
         installments  at such  times  during  said  term as the  Committee  may
         prescribe;  provided,  however,  that no part of an Option  may be made
         exercisable  during the six (6) month period  beginning on the date the
         Option was  granted.  Except as  provided  above and  unless  otherwise
         provided in any  Agreement,  an Option may be  exercised at any time or
         from time to time during the term of the Option.  Such  exercise may be
         as to any or all whole (but no  fractional)  shares  which have  become
         purchasable under the Option.

                  Within a reasonable  time (or such time as may be permitted by
         law) after the Corporation  receives written notice that the Holder has
         elected to  exercise  all or a portion of an Option,  such notice to be
         accompanied by payment in full of the aggregate  Option  exercise price
         of the number of shares of Stock purchased, the Corporation shall issue
         and  deliver  a  certificate   representing   the  shares  acquired  in
         consequence   of  the  exercise  and  any  other  amounts   payable  in
         consequence of such exercise. In the event that a Holder exercises both
         an  Incentive  Option,  or portion  of one,  and a  Nonstatutory  Stock
         Option,  or a portion  of one,  separate  Stock  certificates  shall be
         issued,  one for the Stock subject to the Incentive  Option and one for
         the Stock subject to the Nonstatutory  Stock Option.  The number of the
         shares of Stock  transferrable  due to an exercise  of an Option  under
         this Plan shall not be increased due to the passage of time,  except as
         may be provided in an Agreement;  provided, however, the number of such
         shares  of  Stock  which  are  transferrable  may  increase  due to the
         occurrence  of certain  events  which are fully  described in PARAGRAPH
         6.5.

                  Nothing  in the Plan or in any Option  granted  under the Plan
         shall require the  Corporation to issue any shares upon exercise of any
         Option if such  issuance  would,  in the  opinion  of  counsel  for the
         Corporation,  constitute a violation of the Securities Act or any other
         applicable statute or regulation, as then in effect. At the time of any
         exercise of an Option, the Corporation may, as a condition precedent to
         the exercise of such  Option,  require from the Holder (or in the event
         of  his  death,  his  legal   representatives,   heirs,   legatees,  or
         distributees)  such written  representations,  if any,  concerning  his
         sophistication,  financial  means,  access  to  information  about  the
         Corporation, and intentions with regard to the retention or disposition
         of the  shares  being  acquired  by  exercise  of such  Option and such
         written covenants and agreements,  if any, as to the manner of disposal
         of such shares as, in the opinion of counsel to the Corporation, may be
         necessary  to ensure  that any  disposition  by such  Holder (or in the
         event of his death,  his legal  representatives,  heirs,  legatees,  or
         distributees),  will not involve a violation of the  Securities  Act or
         any other applicable state or federal statute or regulation, as then in
         effect.  Certificates  for shares of Stock,  when issued,  may have the
         following  or  similar  legend,   or  statements  of  other  applicable
         restrictions,   endorsed   on   them,   and  may  not  be   immediately
         transferable:

                  The shares of stock  evidenced by this  certificate  have been
                  issued  to the  registered  owner  in  reliance  upon  written
                  representations  that these  shares  have been  purchased  for
                  investment.  These shares have not been  registered  under the
                  Securities Act of 1933, as amended,  or any  applicable  state
                  securities   laws,   in  reliance   upon  an  exemption   from
                  registration.  Without such registration, these shares may not
                  be  sold,  transferred,  assigned  or  otherwise  disposed  of
                  unless,  in the  opinion  of the  Corporation  and  its  legal
                  counsel,  such sale, transfer,  assignment or disposition will
                  not be in violation of the Securities Act of 1933, as amended,
                  applicable   rules  and  regulations  of  the  Securities  and
                  Exchange  Commission,  and  any  applicable  state  securities
                  laws."


         3.  Paragraph  6.4 is hereby  amended  to delete  the third and  fourth
paragraphs  of  Paragraph  6.4 in their  entirety  and to replace  them with the
following new language:

                  "The provisions of the remainder of this Paragraph shall apply
         to  the  extent  a  Holder's   Agreement  does  not  expressly  provide
         otherwise.  If a  Holder  ceases  to be  an  Eligible  Individual,  the
         portion,  if  any,  of the  Option  that  is  exercisable  but  remains
         unexercised  on the date the Holder stops being an Eligible  Individual
         shall terminate  twenty-four (24) months after such Holder ceases to be
         an Eligible Individual.

                  The portion of the Option that is not  exercisable on the date
         the Holder ceases to be an Eligible  Individual  shall terminate and be
         forfeited  to  the   Corporation   on  the  date  of  such   cessation.
         Notwithstanding  the previous  sentence,  if (i) a Change in Control of
         the Corporation  occurs and, within twenty-four months from the date of
         the  Change in  Control of the  Corporation,  a Holder  ceases to be an
         Eligible  Individual either because (A) the Corporation  terminates the
         Holder's  employment  with the  Corporation for a reason other than Due
         Cause or (B) the Holder  terminates his employment with the Corporation
         due to a Severance Termination by the Holder of the Holder's Employment
         Agreement,  or (ii) a Holder  ceases to be an  Eligible  Individual  by
         reason of death,  any Options held by such Holder shall be  exercisable
         in full on the date such Holder  ceases to be an  Eligible  Individual,
         and no portion of an Option  held by such  Holder  shall  terminate  or
         forfeit on the date such Holder  ceases to be an  Eligible  Individual.
         The  provisions  of this  paragraph of  PARAGRAPH  6.4 shall be applied
         before  the  provisions  of  the  immediately  preceding  paragraph  of
         PARAGRAPH 6.4."

                        INCENTIVE STOCK OPTION AGREEMENT


         THIS  AGREEMENT  is made and  entered  into this day     of     , 199 ,

                  any  Affiliate  (or a  predecessor  of the  Corporation  or an
                  Affiliate) subject to any other incentive stock option (within
                  the meaning of section 422 of the Code) of the  Corporation or

<PAGE>



         For purposes of this Paragraph,  "predecessor  corporation" means (i) a
corporation that was a party to a transaction described in section 425(a) of the
Code (or that would be so described if a substitution  or assumption  under such
section had been effected) with the Corporation,  (ii) a corporation that at the
time the new  incentive  stock option  (within the meaning of section 422 of the
Code)  is  granted,  is  an  Affiliate  of  the  Corporation  or  a  predecessor
corporation of any such corporations,  or (iii) a predecessor corporation of any
such corporations.

         3.       NOTICE OF EXERCISE.  This Incentive Option may be exercised in
whole or in part,  from time to time, in accordance with PARAGRAPH 2, by written
notice to the  Corporation  at the  address  provided in this  Agreement,  which
notice shall:

                  (a) specify the number of whole shares of Stock to be 
purchased and the exercise price to be paid for such shares;

                  (b) if the person  exercising this Incentive Option is not the
Holder  himself,  contain or be  accompanied  by  evidence  satisfactory  to the
Committee of such person's right to exercise this Incentive Option; and

                  (c) be accompanied by payment in full of the purchase price in
the  form  of  cash,  a  certified  or  cashier's  check  to  the  order  of the
Corporation, or a wire transfer of immediately available funds.

         This  Incentive  Option may be exercised  only in  increments  at least
equal to the lesser of one  hundred  (100)  shares or ten  percent  (10%) of the
number of whole shares as to which it is exercisable.

                  4.  INVESTMENT  LETTER.  The Holder  agrees that the shares of
Stock  acquired on exercise of this  Incentive  Option shall be acquired for his
own  account  for  investment  only  and not with a view to,  or for  resale  in
connection  with, any distribution or public offering thereof within the meaning
of the Securities Act or other  applicable  securities laws. If the Committee so
determines, any Stock certificates issued upon exercise of this Incentive Option
shall bear a legend to the effect  that the shares  have been so  acquired.  The
Corporation  may,  but in no event  shall be required  to, bear any  expenses of
complying with the Securities Act, other applicable securities laws or the rules
and  regulations  of  any  national  securities  exchange  or  other  regulatory
authority in connection with the registration,  qualification,  or transfer,  as
the case may be, of this  Incentive  Option or any shares of Stock acquired upon
the exercise thereof.  The foregoing  restrictions on the transfer of the shares
of Stock shall be inoperative if (a) the Corporation  previously shall have been
furnished  with an opinion of  counsel,  satisfactory  to it, to the effect that
such transfer will not require  registration  under the  Securities Act or other
applicable  securities  laws or (b) the  shares  of Stock  shall  have been duly
registered in compliance with the Securities Act and other applicable securities
laws.

         5.    TRANSFER AND EXERCISE OF INCENTIVE OPTION.  This Incentive Option
shall  not be  transferable  except  by  will  or by the  laws  of  descent  and
distribution or pursuant to a qualified  domestic  relations order as defined in
the Code or Title I of the Employee Retirement Income

LABDAL:49156.2   15467-6
                                                         3

Security Act  ("ERISA") or the rules  thereunder.  No  assignment or transfer of
this Incentive Option, whether voluntary or involuntary,  by operation of law or
otherwise,  except a transfer by will or by the laws of descent or  distribution
or pursuant to a qualified  domestic  relations  order as defined in the Code or
Title  I of  ERISA  or the  rules  thereunder,  shall  vest in the  assignee  or
transferee any interest or right whatsoever in this Incentive Option.

         During the Holder's  lifetime,  this Incentive  Option may be exercised
only by him,  his  guardian or legal  representative  or the  recipient  of this
Incentive Option pursuant to a qualified  domestic relations order as defined in
the Code or Title I of ERISA or the rules thereunder.

         6. STATUS OF HOLDER.  The Holder shall not be deemed a  stockholder  of
the  Corporation  with  respect  to any of the  shares of Stock  subject to this
Incentive  Option,  except  to the  extent  that  such  shares  shall  have been
purchased and transferred to him. The Corporation shall not be required to issue
or transfer any certificates for shares of Stock purchased upon exercise of this
Incentive  Option until all  applicable  requirements  of law have been complied
with and such shares shall have been duly listed on any  securities  exchange on
which the Stock may then be listed.

         7. NO EFFECT ON CAPITAL  STRUCTURE.  This  Incentive  Option  shall not
affect the right of the Corporation or any Affiliate to reclassify, recapitalize
or  otherwise  change its capital or debt  structure  or to merge,  consolidate,
convey any or all of its  assets,  dissolve,  liquidate,  windup,  or  otherwise
reorganize.

         8.       EXPIRATION OF INCENTIVE OPTION UPON TERMINATION OF EMPLOYMENT.

         Except as  otherwise  specifically  provided  in this  Agreement,  if a
Holder ceases to be an Eligible  Individual,  the portion, if any, of the Option
that is exercisable  but remains  unexercised on the date the Holder stops being
an Eligible Individual shall terminate twenty-four (24) months after such Holder
ceases to be an Eligible Individual.

         The  portion  of the  Option  that is not  exercisable  on the date the
Holder ceases to be an Eligible  Individual  shall terminate and be forfeited to
the  Corporation  on the date of such  cessation.  Notwithstanding  the previous
sentence,  if (i) a Change in  Control of the  Corporation  occurs  and,  within
twenty-four months from the date of the Change in Control of the Corporation,  a
Holder ceases to be an Eligible  Individual  either because (A) the  Corporation
terminates the Holder's  employment with the Corporation for a reason other than
Due Cause or (B) the Holder  terminates his employment  with the Corporation due
to a Severance  Termination by the Holder of the Holder's Employment  Agreement,
or (ii) a Holder ceases to be an Eligible  Individual  by reason of death,  then
any Options  held by such Holder shall be  exercisable  in full on the date such
Holder ceases to be an Eligible Individual,  and no portion of an Option held by
such Holder shall  terminate or forfeit on the date such Holder  ceases to be an
Eligible  Individual.  The  provisions of this paragraph of PARAGRAPH 8 shall be
applied  before  the  provisions  of  the  immediately  preceding  paragraph  of
PARAGRAPH 8.

         9.       ADJUSTMENTS UPON CHANGES IN CAPITALIZATION, MERGER, ETC.   
Notwithstanding  any  other  provision  of this  Agreement,  in the event of any
change in the number of outstanding shares of Stock

         (a)      effected  without receipt of consideration by the Corporation,
                  by reason of a stock dividend, or split, combination, exchange
                  of shares or other recapitalization,  merger, or otherwise, in
                  which the Corporation is the surviving corporation, or

         (b)      by reason of a spin-off of a part of the Corporation into a 
                  separate entity, or assumptions and conversions of outstanding
                  grants due to an acquisition by the Corporation of a separate 
                  entity,

(1) the aggregate  number and class of shares subject to this  Incentive  Option
and (2) the  exercise  price of this  Incentive  Option  shall be  automatically
adjusted to accurately and equitably reflect the effect of such changes.  In the
event of a dispute  concerning  such  adjustment,  the Committee shall have full
discretion  to  resolve  the  dispute.  The  number  of shares  subject  to this
Incentive  Option shall be  automatically  reduced by any fraction which results
from any adjustment made pursuant to this Paragraph.

         In the event of:

(a)  a dissolution or liquidation of the Corporation,

(b)  a merger or consolidation  (other than a merger effecting a reincorporation
     of the  Corporation in another state or any other merger or a consolidation
     in  which  the   stockholders  of  the  surviving   corporation  and  their
     proportionate  interests in the surviving corporation immediately after the
     merger or consolidation are substantially  identical to the stockholders of
     the  Corporation  and  their  proportionate  interests  in the  Corporation
     immediately  prior to the merger or consolidation) in which the Corporation
     is not the  surviving  corporation  (or survives  only as a  subsidiary  of
     another  corporation  in a  transaction  in which the  stockholders  of the
     parent of the Corporation and their  proportionate  interests in the parent
     immediately  after the transaction are not  substantially  identical to the
     stockholders of the Corporation and their  proportionate  interests therein
     immediately prior to the transaction;  provided that the Board of Directors
     may at any  time  prior  to  such a  merger  or  consolidation  provide  by
     resolution that the foregoing  provisions of this  parenthetical  shall not
     apply if a majority of the board of  directors  of such parent  immediately
     after the transaction consists of individuals who constituted a majority of
     the Board of Directors immediately prior to the transaction), or

(c)  a transaction in which any person (other than Cairn Energy PLC) becomes the
     owner of 50% or more of the total  combined  voting power of all classes of
     stock of the Corporation (provided, however, that the Board of Directors


LABDAL:49156.2   15467-6
                                                         5

<PAGE>



     may at any time prior to such  transaction  provide by resolution that this
     Subparagraph  (c) shall not apply if such acquiring person is a corporation
     and a  majority  of the board of  directors  of the  acquiring  corporation
     immediately after the transaction consists of individuals who constituted a
     majority of the Board of Directors  immediately prior to the acquisition of
     such 50% or more total combined voting power)

the Board of Directors  may, at its election,  as of the effective  time of such
transaction, either (1) change the number and kind of shares of stock (including
substitution of shares of another  corporation) and exercise price in the manner
it deems appropriate, provided, however, that in no event may any change be made
under this Paragraph which would constitute a "modification"  within the meaning
of section  425(h)(3) of the Code, or (2) purchase the Option from the Holder by
tendering  cash equal to the Fair Market Value of the Stock  represented  by the
Option  less the  exercise  price of the  Option  specified  in this  Agreement,
without  regard to the  determination  as to the  periods  and  installments  of
exercisability made pursuant to this Agreement,  if (and only if) the Option has
not at that time expired or been terminated.

         10.    COMMITTEE AUTHORITY.  Any question concerning the interpretation
     of  this  Agreement,  any  adjustments  required  to  be  made  under  this
     Agreement,  and any controversy  which may arise under this Agreement shall
     be determined by the Committee in its sole discretion.

         11.  NOTICE  OF  DISQUALIFYING  DISPOSITION.  In  order to  enable  the
Corporation  to avail  itself of any  income  tax  deduction  to which it may be
entitled,  the Holder shall notify the  Corporation  of his intent to dispose of
any of the shares of Stock  purchased  pursuant to this Incentive  Option within
two (2) years  from the date of the grant of the  Incentive  Option  and one (1)
year from the date of exercise of the Incentive Option,  and promptly after such
disposition  the Holder shall notify the  Corporation of the number of shares of
Stock disposed of, the dates of acquisition and disposition of such shares,  and
the  consideration,  if any,  received  on  such  disposition.  Nothing  in this
Paragraph,  however,  shall  give the  Holder  any right to dispose of shares of
Stock in a manner that is  inconsistent  with any  provision  of the Plan or any
Paragraph of this  Agreement.  If in connection  with any such  disposition  the
Corporation  becomes liable for  withholding  taxes and has no amounts owing the
Holder with which to  discharge  its  withholding  obligation,  the Holder shall
provide the  Corporation  with the amount needed to discharge the  Corporation's
withholding obligation and shall indemnify the Corporation against any penalties
it may  incur  through  its  inability  to apply  amounts  owing  the  Holder in
discharge of its withholding obligation.

that this  Incentive  Option is or will be determined to be an "incentive  stock
option" within such section or any other section of the Internal Revenue Code.

     in whole or in part,  from time to time, in accordance with PARAGRAPH 2, by
     written  notice  to  the  Corporation  at  the  address  provided  in  this
     Agreement, which notice shall:

                  (a)specify the number of whole shares of Stock to be purchased

Committee of such person's right to exercise this Nonstatutory Option; and

securities laws or the rules and regulations of any national securities exchange
or  other   regulatory   authority   in   connection   with  the   registration,
qualification,  or transfer,  as the case may be, of this Nonstatutory Option or
any shares of Stock acquired upon the exercise of this Nonstatutory  Option. The
foregoing  restrictions  on the  transfer  of  the  shares  of  Stock  shall  be
inoperative if (a) the Corporation  previously shall have been furnished with an
opinion of counsel,  satisfactory  to it, to the effect that such  transfer will
not require registration under the Securities Act or other applicable securities
laws,  or (b) the shares of Stock shall have been duly  registered in compliance
with the Securities Act and other applicable securities laws.

         5.  TRANSFER AND EXERCISE OF  NONSTATUTORY  OPTION.  This  Nonstatutory
Option  shall not be  transferable  except by will or by the laws of descent and
distribution or pursuant to a qualified  domestic  relations order as defined in
the Code or Title I of the Employee  Retirement Income Security Act ("ERISA") or
the rules  thereunder.  No assignment or transfer of this  Nonstatutory  Option,
whether  voluntary or  involuntary,  by operation of law or otherwise,  except a
transfer  by will or by the laws of descent or  distribution  or  pursuant  to a
qualified domestic relations order as defined in the Code or Title I of ERISA or
the rules  thereunder,  shall vest in the assignee or transferee any interest or
right whatsoever in this Nonstatutory Option.

         During the Holder's lifetime, this Nonstatutory Option may be exercised
only by him,  his  guardian  or legal  representative  or the  recipient  of the
Nonstatutory  Option pursuant to a qualified domestic relations order as defined
in the Code or Title I of ERISA or the rules thereunder.

         6. STATUS OF HOLDER.  The Holder shall not be deemed a  stockholder  of
the  Corporation  with  respect  to any of the  shares of Stock  subject to this
Nonstatutory  Option,  except to the  extent  that such  shares  shall have been
purchased and transferred to him. The Corporation shall not be required to issue
or transfer any certificates for shares of Stock purchased upon exercise of this
Nonstatutory Option until all applicable requirements of law have been satisfied
and such shares shall have been duly listed on any securities  exchange on which
the Stock may then be listed.

         7. NO EFFECT ON CAPITAL STRUCTURE.  This Nonstatutory  Option shall not
affect the right of the Corporation or any Affiliate to reclassify, recapitalize
or  otherwise  change its capital or debt  structure  or to merge,  consolidate,
convey any or all of its  assets,  dissolve,  liquidate,  windup,  or  otherwise
reorganize.

         8.    EXPIRATION OF NONSTATUTORY OPTION UPON TERMINATION OF EMPLOYMENT.

         Except as  otherwise  specifically  provided  in this  Agreement,  if a
Holder ceases to be an Eligible  Individual,  the portion, if any, of the Option
that is exercisable  but remains  unexercised on the date the Holder stops being
an Eligible Individual shall terminate twenty-four (24) months after such Holder
ceases to be an Eligible Individual.

         The  portion  of the  Option  that is not  exercisable  on the date the
Holder ceases to be an Eligible  Individual  shall terminate and be forfeited to
the  Corporation  on the date of such  cessation.  Notwithstanding  the previous
sentence, if (i) a Change in Control of the Corporation


LABDAL:49157.2   15467-6
                                                         3

occurs and, within  twenty-four months from the date of the Change in Control of
the Corporation, a Holder ceases to be an Eligible Individual either because (A)
the  Corporation  terminates the Holder's  employment with the Corporation for a
reason other than Due Cause or (B) the Holder terminates his employment with the
Corporation  due to a  Severance  Termination  by  the  Holder  of the  Holder's
Employment  Agreement,  or (ii) a Holder ceases to be an Eligible  Individual by
reason of death,  then any Options held by such Holder shall be  exercisable  in
full on the date such Holder ceases to be an Eligible Individual, and no portion
of an Option held by such  Holder  shall  terminate  or forfeit on the date such
Holder ceases to be an Eligible Individual.  The provisions of this paragraph of
PARAGRAPH 8 shall be applied before the provisions of the immediately  preceding
paragraph of PARAGRAPH 8.

         9.       ADJUSTMENTS UPON CHANGES IN CAPITALIZATION, MERGER, ETC.  
     Notwithstanding any other provision of this Agreement,  in the event of any
     change in the number of outstanding shares of Stock

         (a)      effected  without receipt of consideration by the Corporation,
                  by reason of a stock dividend, split, combination, exchange or
                  other  recapitalization,  merger,  or otherwise,  in which the
                  Corporation is the surviving corporation, or

         (b)      by reason of a spin-off of a  part of the  Corporation  into a
                  separate entity, or assumptions and conversions of outstanding
                  grants due to an acquisition by the  Corporation of a separate
                  entity,

(1) the aggregate number and class of shares subject to this Nonstatutory Option
and (2) the exercise price of this  Nonstatutory  Option shall be  automatically
adjusted to accurately and equitably reflect the effect of such changes.  In the
event of a dispute  concerning  such  adjustment,  the Committee shall have full
discretion  to  resolve  the  dispute.  The  number  of shares  subject  to this
Nonstatutory Option shall be automatically reduced by any fraction which results
from any adjustment made pursuant to this Paragraph.

In the event of:

     (a) a dissolution or liquidation of the Corporation,

     (b)  a  merger  or   consolidation   (other  than  a  merger   effecting  a
     reincorporation  of the Corporation in another state or any other merger or
     consolidation  in which the  stockholders of the surviving  corporation and
     their  proportionate  interests in the  surviving  corporation  immediately
     after the  merger  or  consolidation  are  substantially  identical  to the
     stockholders of the Corporation  and their  proportionate  interests in the
     Corporation  immediately prior to the merger or consolidation) in which the
     Corporation  is not  the  surviving  corporation  (or  survives  only  as a
     subsidiary  of  another   corporation   in  a  transaction   in  which  the
     stockholders  of the  parent of the  Corporation  and  their  proportionate
     interests  in  the  parent   immediately  after  the  transaction  are  not
     substantially  identical to the  stockholders  of the Corporation and their
     proportionate interests therein

     immediately prior to the transaction;  provided, however, that the Board of
     Directors may at any time prior to such a merger or  consolidation  provide
     by resolution that the foregoing provisions of this parenthetical shall not
     apply if a majority of the board of  directors  of such parent  immediately
     after the transaction consists of individuals who constituted a majority of
     the Board of Directors immediately prior to the transaction), or

     (c) a transaction in which any person (other than Cairn Energy PLC) becomes
     the owner of 50% or more of the total combined  voting power of all classes
     of stock of the Corporation (provided, however, that the Board of Directors
     may at any time prior to such  transaction  provide by resolution that this
     Subparagraph  (c) shall not apply if such acquiring person is a corporation
     and a  majority  of the board of  directors  of the  acquiring  corporation
     immediately after the transaction consists of individuals who constituted a
     majority of the Board of Directors  immediately prior to the acquisition of
     such 50% or more total combined voting power)

the Board of Directors  may, at its election,  as of the effective  time of such
transaction, either (1) change the number and kind of shares of stock (including
substitution of shares of another  corporation) and exercise price in the manner
it deems  appropriate,  or (2)  purchase the Option from the Holder by tendering
cash equal to the Fair Market Value of the Stock  represented by the Option less
the exercise price of the Option specified in this Agreement,  without regard to
the  determination  as to the periods and  installments of  exercisability  made
pursuant  to this  Agreement,  if (and only if) the  Option has not at that time
expired or been terminated.

         10.    COMMITTEE AUTHORITY.  Any question concerning the interpretation
of this Agreement, any adjustments required to be made under this Agreement, and
any controversy  which may arise under this Agreement shall be determined by the
Committee in its sole discretion.

         11. PLAN  CONTROLS.  The terms of this  Agreement  are  governed by the
terms of the Plan,  a copy of which is  attached as Exhibit A and made a part of
this Agreement as if fully set forth in this  Agreement,  and in the case of any
inconsistency between the terms of this Agreement and the terms of the Plan, the
terms of the Plan shall control.

Agreement,  such notice must be in writing and personally delivered,  telecopied
