ITEM 1. BUSINESS

                               BUSINESS OVERVIEW

     DeepTech is a diversified energy company engaged, through the
Subsidiaries, in offshore contract drilling services and the acquisition,
development, production, processing, transportation and marketing of, and the
exploration for, oil and gas located primarily offshore the United States in
the Gulf of Mexico (the "Gulf").  The Company's activities are concentrated
primarily in the Flextrend (water depths of 600 to 1,500 feet) and Deepwater
(water depths of greater than 1,500 feet) areas of the Gulf.  Since its
formation in 1989, the Company has acquired (i) interests in or constructed
eight natural gas pipelines (the "Pipelines") located offshore Louisiana and
Texas as well as an interest in a sour crude oil system, (ii) oil and gas
leases which currently cover 94,720 gross (82,580 net) acres in the Gulf and
(iii) two second generation semisubmersible drilling rigs.


                              BUSINESS OPERATIONS

     DeepTech conducts its operations through the Subsidiaries, each of which
is focused on an aspect of the oil and gas business.  The following provides
certain information regarding DeepTech's operations in the oil and gas industry
as of August 30, 1996, unless otherwise indicated.

TRANSPORTATION SERVICES

     GENERAL

     DeepTech conducts transportation services through the Partnership, a
master limited partnership traded on the New York Stock Exchange ("NYSE") under
the symbol "LEV."  Leviathan owns a 27.3% effective interest in the Partnership
(23.2% effective interest net to DeepTech), represented by a 1% general partner
interest, a 25.6% limited partner interest evidenced by 3,145,947 common units
in the Partnership (the "Common Units") and a 1.0101% nonmanaging interest in
certain limited liability company subsidiaries of the Partnership (the
"Operating Companies").  On August 30, 1996, the public held 9,037,500
preference units in the Partnership (the "Preference Units").  The closing
price of the Preference Units on the NYSE on such date was $40 1/4 per
Preference Unit.

     The Partnership's assets include interests in (i) the Pipelines, (ii) a
crude oil pipeline system (the "Poseidon Oil Pipeline"), (iii) five
strategically located multipurpose platforms, (iv) three producing oil and gas
properties, (v) an overriding royalty interest and (vi) a dehydration facility.

     THE PIPELINES

     General.  The Partnership, through the Operating Companies and Tarpon
Transmission Company ("Tarpon"), owns interests in the Pipelines which are
strategically located offshore Louisiana and eastern Texas and gather and
transport natural gas for producers, marketers, pipelines and end-users for a
fee.  The Pipelines include 981 miles of pipeline with a throughput capacity of
approximately 5.6 Bcf of gas per day as of June 30, 1996.  During the years
ended December 31, 1993, 1994 and 1995, the Pipelines transported an average of
approximately 2.3 Bcf, 2.3 Bcf and 2.4 Bcf, respectively, of gas per day.  Each
of the Pipelines interconnects with one or more long line transmission
pipelines that provide access to multiple markets in the eastern half of the
United States.

     None of the Pipelines functions as a merchant to purchase and resell gas,
thus avoiding the commodity risk associated with the purchase and resale of
gas.  Each of Stingray Pipeline Company ("Stingray"), High Island Offshore
System ("HIOS"), U-T Offshore System ("UTOS") and Tarpon (together, the
"Regulated Pipelines") is currently classified as a "natural gas company" under
the Natural Gas Act of 1938, as amended (the "NGA"), and is therefore subject
to extensive regulation by the Federal Energy Regulatory Commission ("FERC"),
including regulation of rates.  Each of Manta Ray Gathering Company, L.L.C.
("Manta Ray") (formerly Louisiana Offshore Gathering Systems, L.L.C. ("LOGS")
), Green Canyon Pipe Line Company, L.L.C. ("Green Canyon"), Ewing Bank
Gathering Company, L.L.C. ("Ewing Bank") and Viosca Knoll Gathering Company,
L.L.C. ("Viosca Knoll Gathering") is not currently considered a "natural gas
company" under the NGA.  As such, these companies are not subject to extensive
rate regulation by the FERC.  As a result, Green Canyon, Ewing Bank, Viosca
Knoll Gathering and Manta Ray currently conduct operations, including the
negotiation of transportation rates with their customers, without requiring
approval by the FERC.

     The following table sets forth certain information with respect to the
Pipelines.  The throughput information represents the average throughput net to
the Partnership's interest in the Pipelines.

     The following provides a brief description of each of the Pipelines and
certain related facilities.

     Combined Manta Ray System.  In May 1996, Manta Gathering Systems Inc. and
Manta Ray Pipeline Holding Company, L.L.C. were merged with and into Manta Ray
and the respective assets of each entity were integrated to form the Combined
Manta Ray System.  The LOGS system included three separate gathering lines, all
of which are located offshore Louisiana in the Gulf.  In total, these three
lines consist of 70 miles of 12-inch to 24-inch diameter pipeline.  Each of the
three lines interconnects offshore with the east leg of Transco Energy
Company's ("Transco") Southeast Louisiana Lateral ("South Lateral") which
provides the outlet for gas transported on LOGS to the shore in eastern
Louisiana.  As a result of recent interconnections, a shipper on the Combined
Manta Ray System now has the ability to have its gas delivered to various
onshore markets by Transco, Trunkline Gas Co. ("Trunkline") or ANR Pipeline
Company ("ANR"), a subsidiary of The Coastal Corporation.

     Prior to the merger, the Manta Ray system was comprised of approximately
51 miles of dual 14-inch diameter and 16-inch diameter pipelines, each
extending from Ewing Bank Block 29 northwesterly to Ship Shoal Block 207 and a
shallow water junction platform and certain processing facilities at Ship Shoal
Block 207 (the "SS 207 Platform").  The Manta Ray system was acquired by the
Partnership in a series of transactions which resulted in the acquisition of a
100% ownership interest during 1994.

     The Combined Manta Ray System includes two other strategically located,
multi-purpose platforms in addition to the SS 207 Platform.  In August 1993,
the Partnership acquired the Ship Shoal Block 332 Platform (the "SS 332
Platform") and a six-inch diameter, six-mile crude oil pipeline.  In May 1994,
the Partnership purchased the South Timbalier Block 292 Platform (the "ST 292
Platform"), which is located at the easternmost terminus of Manta Ray's
southeast gathering pipeline, and approximately eight miles of six-inch
diameter oil pipeline connecting South Timbalier Block 292 with South Timbalier
Block 295.

     In 1994, the Partnership constructed an extension to the LOGS system (the
"Ship Shoal Pipeline Extension") comprised of two four-inch diameter and two
six-inch diameter flow lines, approximately 3.2 miles long, from the SS 332
Platform to the Ship Shoal Block 331 platform owned by Tatham Offshore. Under a
gathering and processing agreement between the Partnership and Tatham Offshore,
the Partnership is obligated to transport oil and gas production from Ship
Shoal Block 331 to the SS 332 Platform and in return Tatham Offshore was
required to pay certain demand charges and processing fees.  Demand charges
were payable under this agreement over a five-year period ending June 1999.
The Ship Shoal Pipeline Extension and related processing facilities were placed
into service in July 1994.  During late 1994, all of Tatham Offshore's wells at
Ship Shoal Block 331 experienced completion and production problems and are
currently shut-in.  As a result, the Partnership is not currently receiving
processing fees under this agreement.  Although the demand charges were due
whether or not any production was actually transported or processed, effective
February 1, 1996, the demand charge obligation was canceled by the Partnership
in exchange for certain consideration from Tatham Offshore.  See "-- Customers
and Contracts -- Transportation, Processing and Platform Access Agreements with
Tatham Offshore" and "-- Exploration and Production -- Oil and Gas Properties
- -- Tatham Offshore's Oil and Gas Properties -- Genuine Risk (Ship Shoal Block
331)."

     Partly as a result of the integration of the Manta Ray system with the
LOGS system, the Partnership has been successful in obtaining an agreement with
Phillips Petroleum Company ("Phillips"), Amoco Production Company ("Amoco") and
Anadarko Petroleum Corporation ("Anadarko") for the gathering of gas from the
Mahogany field.  Under the agreement, the Partnership will own approximately
nine miles of new 16-inch diameter pipeline connecting the Mahogany field to a
subsea location on its existing system. The agreement provides for the
gathering of all of the Mahogany field gas production for the life of the
reserves.  Initial gas deliveries under this agreement are projected to begin
in December 1996.

     In connection with the formation of Poseidon Oil Pipeline Company, L.L.C.
("POPCO"), the owner and operator of the Poseidon Oil Pipeline, the Partnership
and POPCO entered into a lease agreement and purchase option agreement.  Under
the lease agreement, POPCO will temporarily lease a portion of the Manta Ray
14-inch line to handle oil until the second phase of the Poseidon Oil Pipeline
is completed.  In addition, the Partnership constructed an interconnection to
connect the 14-inch Manta Ray line with the Poseidon Oil Pipeline at the SS 332
Platform to enable crude oil deliveries to be made to the Ship Shoal 207
Platform and then through a newly constructed 16-inch line from Ship Shoal
Block 207 to the Eugene Island 


                                      3


<PAGE>   6

Pipeline System for transport to shore.  The Partnership anticipates that the
Manta Ray 14-inch line and the newly constructed 14 and 16-inch lines will be
converted to gas service once the lease with POPCO has terminated.

     In December 1994, in connection with the purchase of the remaining
interest in the Manta Ray system, the Partnership and Enserch Exploration, Inc.
("Enserch") entered into agreements pursuant to which Enserch committed its oil
and gas reserves to be produced from the Allegheny field located in Green
Canyon Block 254 to the Manta Ray system for the life of the lease.  Under its
organizational documents, POPCO has the option to purchase the Enserch oil
dedication and any related assets.

     On July 8, 1996, the Partnership and affiliates of Marathon Oil Company
("Marathon") and Shell Oil Company ("Shell") announced plans to build and
operate an interstate natural gas pipeline system and a connecting gathering
system to serve growing production areas in the Green Canyon area of the Gulf.
The total cost of the two systems, including the Combined Manta Ray System,
currently owned by the Partnership, is approximately $270.0 million.  The new
jurisdictional interstate pipeline, to be named "Nautilus", will consist of a
30-inch line downstream from Ship Shoal Block 207 connecting to the Marathon
operated Burns Point Gas Plant and other area gas plants. Upstream of the Ship
Shoal 207 terminal, the Combined Manta Ray System will be extended into a
broader gathering system that would serve shelf and deepwater production around
Ewing Bank Block 873 to the east and Green Canyon Block 65 to the west.
Marathon and Shell have significant deep water acreage positions in the area,
including the recently announced Troika field (Green Canyon Block 244), and
would provide the majority of the capital funding for the new construction.
The Partnership would provide some funding along with the contribution of the
Combined Manta Ray System.  The consummation of this joint venture is subject
to the negotiation and execution of definitive documents.

     Green Canyon Pipe Line Company.  The Green Canyon system consists of
approximately 66 miles of 10-inch to 20-inch diameter pipeline and transports
gas from the South Marsh Island, Eugene Island, Garden Banks and Green Canyon
areas in the Gulf to the west leg of Transco's South Lateral for transportation
to shore in eastern Louisiana.  Green Canyon is in the process of constructing
a one mile lateral to a producing platform being installed by Amerada Hess on
South Marsh Island Block 192.

     In November 1995, the Partnership and a subsidiary of Natural Gas Pipeline
Company of America ("NGPL") completed the construction and installation of a
multipurpose platform on Garden Banks Block 72 (the "GB 72 Platform").  The
Partnership, as operator, has placed three wells on production and is
continuing drilling operations on Garden Banks Block 72 from the GB 72
Platform.  See "-- Exploration and Production -- Oil and Gas Properties --
Flextrend Development's Oil and Gas Properties -- Garden Banks Block 72
(Spectacular Bid)."  The GB 72 Platform also acts as the westernmost terminus
of the Poseidon Oil Pipeline.

     Ewing Bank Gathering Company.  In August 1993, the Partnership completed
its Ewing Bank system. The Ewing Bank system consists of approximately seven
miles of 3 1/2-inch diameter gathering lines connecting Tatham Offshore's Ewing
Bank 914 #2 well to a production platform owned by BP Exploration & Oil, Inc.
located at Ewing Bank Block 826.  The Ewing Bank 914 #2 well was originally
completed as a gas/condensate well.  An unanticipated change in the character
of the production from the well resulted in a paraffin build-up in the subsea
flow lines, impairing production from the well and requiring the Partnership to
replace the flow lines.  The replacement of the flow lines was completed by the
Partnership in December 1994 and production resumed at that time.  In February
1996, the Ewing Bank 914 #2 well began producing water in addition to oil and
gas.  As a result of the water production, oil production has been declining
since February 1996.  Effective February 1, 1996, the demand charge obligation
was canceled by the Partnership in exchange for certain consideration from
Tatham Offshore. See "-- Customers and Contracts -- Transportation, Processing
and Platform Access Agreements with Tatham Offshore" and "-- Exploration and
Production -- Oil and Gas Properties -- Tatham Offshore's Oil and Gas
Properties -- Seattle Slew (Ewing Bank Blocks 914 and 915)."

     Tarpon Transmission Company.  The Tarpon system includes a regulated gas
transmission facility operated by the Partnership consisting of approximately
40 miles of 16-inch diameter offshore pipeline located on the edge of the Outer
Continental Shelf ("OCS"), offshore Louisiana.  The Tarpon system extends from
the Ship Shoal Block 274, South Addition, to the Eugene Island Area, South
Addition in an area of the Gulf adjacent to Green Canyon's gathering system.

                                      4

     Viosca Knoll System.  In May 1994, the Partnership and Tenneco Deepwater
Gathering Company, L.L.C., a subsidiary of Tenneco, Inc. ("Tenneco Deepwater"),
formed Viosca Knoll Gathering to construct and operate (i) an approximate
94-mile, 20-inch diameter pipeline from a platform on Main Pass Block 252 owned
by Shell Offshore, Inc. ("Shell Offshore") to a pipeline owned by Tennessee Gas
Pipeline Company at South Pass Block 55 and (ii) a six-mile, 16-inch diameter
pipeline from an interconnection with the 20-inch diameter pipeline at Viosca
Knoll Block 817 to a pipeline owned by Southern Natural Gas Company at Main Pass
Block 289 (the "Viosca Knoll System").  The Viosca Knoll System was completed
and placed into service in November 1994.

     In August 1995, the Partnership completed construction and installation of
a multi-purpose platform at Viosca Knoll Block 817 (the "VK 817 Platform").
The VK 817 Platform, which is owned 100% by the Partnership, serves as a
junction platform for the Viosca Knoll System and a landing site for production
from deeper water projects in the vicinity.  The Partnership is currently
conducting drilling operations from the VK 817 Platform.  Tatham Offshore, as
working interest owner in the Viosca Knoll Block 817 lease, is obligated to pay
the Partnership a monthly demand charge for access to the VK 817 Platform and
related processing facilities. In addition, the Partnership has a contract with
Walter Oil & Gas which provides for payment on a per unit basis for each barrel
of oil or Mcf of gas processed upon the VK 817 Platform.  The Partnership also
has a contract with the partners of the Ram-Powell lease operated by Shell in
the Viosca Knoll area of the Gulf allowing production from this lease area to
land on the VK 817 Platform.

     Stingray Pipeline Company.  The Stingray system is owned 50% by the
Partnership and 50% by a subsidiary of NGPL.  The Stingray system consists of
approximately 361 miles of six-inch to 36-inch diameter pipeline and transports
natural gas from the High Island, West Cameron, East Cameron and Vermilion
lease areas in the Gulf to onshore transmission systems at Holly Beach, Cameron
Parish, Louisiana.  In November 1993, Stingray completed construction of 12
miles of 16-inch diameter pipeline connecting the Garden Banks Block 191 lease
operated by Chevron U.S.A. Production Company to the Stingray system.  In March
1996, Stingray completed the construction of 31 miles of 20-inch diameter
pipeline connecting the GB 72 Platform to the Stingray system at Vermilion
Block 320.  The Stingray system is operated by NGPL.

     High Island Offshore System.  The HIOS system is owned 40% by the
Partnership, 40% by subsidiaries of ANR and 20% by a subsidiary of NGPL.  The
HIOS system transports gas from certain blocks in the High Island area of the
Gulf off the eastern coast of Texas to a junction platform owned by HIOS
located in West Cameron Block 167 where it interconnects with UTOS and a
pipeline owned by ANR for further transportation to points onshore.  The HIOS
system has approximately 203 miles of pipeline comprised of three supply
laterals, the West, Central and East Laterals, that connect to a 42-inch
diameter mainline.  The HIOS system receives gas from fields located in the
Galveston, Garden Banks, High Island, West Cameron and East Breaks areas of the
Gulf and is operated by ANR.

     U-T Offshore System.  The UTOS system is owned 33 1/3% by the Partnership,
33 1/3% by a subsidiary of ANR and 33 1/3% by a subsidiary of NGPL.  The UTOS
system transports gas from the terminus of the HIOS system at West Cameron
Block 167 to the Johnson Bayou processing facility (the "Johnson Bayou Plant").
The UTOS system consists of approximately 30 miles of 42-inch diameter pipeline
extending from a point of interconnection with HIOS at West Cameron Block 167
to the Johnson Bayou Plant where it interconnects with several pipelines.  The
UTOS system is essentially an extension of the HIOS system, as almost all of
the gas transported through UTOS comes from HIOS.  UTOS also owns the Johnson
Bayou Plant, which provides primary gas and liquids separation and gas
dehydration for natural gas transported on HIOS and UTOS.  The UTOS system is
operated by ANR.

     OIL PIPELINE OPERATIONS - POSEIDON OIL PIPELINE

     In August 1995, the Partnership began construction of the Poseidon Oil
Pipeline, a major new sour crude oil system in the Gulf.  The Poseidon Oil
Pipeline is intended to address the need of offshore producers for additional
sour crude oil pipeline capacity in the Flextrend and Deepwater areas of the
Gulf for redelivery to existing and new markets onshore Louisiana.  In February
1996, the Partnership and Texaco, Inc. ("Texaco") formed POPCO, which at
inception, was 50% owned by Poseidon Pipeline Company, L.L.C. ("Poseidon LLC"),
an Operating Company of the Partnership, and 50% owned by Texaco Trading and
Transportation, Inc. ("Texaco Trading"), a subsidiary of Texaco.  POPCO was
formed 


                                      5


<PAGE>   8
to construct, own and operate the Poseidon Oil Pipeline.  Pursuant to the 
terms of organizational documents, Poseidon LLC initially contributed
assets, at net book value, related to the construction of the initial phase of
the Poseidon Oil Pipeline as well as certain dedication agreements with
producers, and Texaco Trading initially contributed an equivalent amount of
cash as well as its rights under certain agreements.  In July 1996, Marathon
joined POPCO by contributing its interest in 58 miles of nearby crude oil
pipelines and dedicating its portion of oil reserves attached to such pipelines
to the Poseidon Oil Pipeline for transportation.  As a result, each of the
Partnership and Texaco Trading now owns a 36% interest in POPCO and Marathon
owns the remaining 28% interest.

     Management decisions related to the Poseidon Oil Pipeline are made by a
management committee comprised of representatives with authority appointed in
direct relationship to the ownership interest.  The Poseidon Oil Pipeline is
operated by a subsidiary of Texaco.  It is anticipated that the additional
construction and installation costs of the Poseidon Oil Pipeline will be funded
pursuant to the POPCO Credit Facility as discussed in Item 7. "Management's
Discussion and Analysis of Financial Condition and Results of Operations --
Liquidity and Capital Resources -- Leviathan/The Partnership."

     The Poseidon Oil Pipeline will ultimately consist of approximately 200
miles of 16 to 24 inch pipeline capable of delivering up to 400,000 barrels per
day of sour crude oil production to multiple market outlets onshore Louisiana.
The initial 117-mile segment, which extends easterly from Garden Banks Block 72
to Ship Shoal Block 332, was placed in service in April 1996.  The second
phase, an 83-mile segment, extending in a northerly direction from the SS 332
Platform to Calliou Island, Louisiana, is currently under construction and is
scheduled to be completed by the fourth quarter of 1996.  Until the second
phase of the Poseidon Oil Pipeline is completed, POPCO is using a portion of
the Manta Ray system's 14-inch line which extends from the SS 332 Platform to a
platform located in Ship Shoal Block 207.  From the Ship Shoal 207 Platform,
the oil moves through an interconnection with the Texaco operated Eugene Island
Pipeline System to Calliou Island.

     In order to move crude oil from the terminus of the Poseidon Oil Pipeline
at Calliou Island to Houma or St. James, Louisiana, POPCO anticipates using
existing Texaco pipelines, or as conditions warrant, using other pipelines
acquired or constructed by POPCO.  POPCO has an agreement pursuant to which
Texaco Pipelines Inc. will provide downstream capacity for POPCO from Larose
and/or Houma, Louisiana to St. James, Louisiana.

     Recently, POPCO has been successful in obtaining long-term commitments for
production from several properties containing significant reserves.  POPCO has
contracted with Phillips, Amoco and Anadarko with respect to the Mahogany
field, Newfield Exploration with respect to Vermilion Block 398, Mobil Oil with
respect to South Marsh Island Block 205, and the Partnership and MidCon Corp.
with respect to both Garden Banks Block 72 and Garden Banks Block 117.  In
addition, discussions are currently pending with a number of other producers
regarding commitments of reserves to the Poseidon Oil Pipeline.

     OIL AND GAS SUPPLY

     The reserves that are currently available for transportation on the
Pipelines and the Poseidon Oil Pipeline are depleting assets and, as such, will
be produced over a finite period.  Each of the Pipelines and the Poseidon Oil
Pipeline must access additional reserves to offset the natural decline in
production from existing wells connected to the Pipelines and the Poseidon Oil
Pipeline.  Management believes that there will be sufficient reserves available
to the Pipelines for transportation to maintain throughput at or near current
levels for at least the next five years.  Initial deliveries from the Poseidon
Oil Pipeline began in April 1996, and management believes that there will be
significant increases in reserves attached to and transportation through the
Poseidon Oil Pipeline over the next several years.  As more fully discussed
below, each of the Combined Manta Ray System, and the Green Canyon, Ewing Bank,
Tarpon and Stingray systems experienced a decrease in transportation volumes in
1995 as compared with the previous year. Conversely, each of the HIOS and UTOS
systems experienced increases in volumes transported in 1995 as compared with
1994.  In addition, the Partnership placed the Viosca Knoll System and a
portion of the Manta Ray system in service in November and December 1994,
respectively, and such systems had significant volume increases in 1995 as
compared with 1994.

     For the year ended December 31, 1995, the Combined Manta Ray System
experienced a throughput decline of 3% from the previous year.  This decrease
in throughput was a result of lower production from 

                                      6


<PAGE>   9
the major connected fields. The Green Canyon system's average daily throughput
declined 8% for 1995 as compared with 1994.  This decline was due to the gradual
decrease in deliverability from the fields connected to the southeast lateral of
the Green Canyon system.  However, in recent months additional connections to
the Green Canyon system have increased throughput to approximately 165 MMcf of 
gas per day, as compared with an average throughput for 1995 of 71 MMcf of gas
per day.

     HIOS experienced an increase in transportation volume of 1% for the year
ended December 31, 1995 as compared with the previous year.  For the quarter
ended June 30, 1996, HIOS daily throughput averaged 955 MMcf per day as
compared to an average daily throughput of 819 MMcf per day in the year ended
December 31, 1995.  HIOS accesses the East Breaks and Garden Banks areas of the
Flextrend and Deepwater areas of the Gulf.  Although these areas have not
experienced as much exploration and development activity as some areas of the
Flextrend, management believes that development in these and other areas served
by HIOS is likely to occur in future years, resulting in additional throughput
on HIOS, and partially offsetting the continuing decline in reservoir
deliverability from existing wells connected to HIOS. UTOS experienced an
increase in transportation volume of 3% for the year ended December 31, 1995 as
compared with the previous year.
                                     
     The Ewing Bank system connects Tatham Offshore's Ewing Bank 914 #2 well to
a shallow water platform located at Ewing Bank Block 826.  In February 1996,
the Ewing Bank 914 #2 well began producing water in addition to oil and gas.
As a result of the water production, the well produces less oil, on a daily
basis, than the quantity produced prior to February 1996.  All of the
production from Tatham Offshore's eight block Ewing Bank project area is
dedicated to the Partnership for transportation.  See -- The Pipelines -- Ewing
Bank Gathering Company", "Customers and Contracts -- Transportation, Processing
and Platform Access Agreements with Tatham Offshore" and "-- Exploration and
Production -- Oil and Gas Properties -- Tatham Offshore's Oil and Gas
Properties -- Seattle Slew (Ewing Bank Blocks 914 and 915)".

     The Tarpon system experienced a throughput decrease of 30% for the year
ended December 31, 1995 as compared with the previous year.  This decrease was
primarily attributable to the normal decline of existing connected fields.  For
the year ended December 31, 1995, the Stingray system experienced a decrease in
throughput of 4% as compared with the previous year.

     CUSTOMERS AND CONTRACTS

     Principal Customers.  Union Oil Company of California ("UNOCAL"), Chevron
U.S.A., Inc. ("Chevron") and Shell Gas Trading Company ("Shell Trading")
accounted for approximately 22%, 15% and 11%, respectively, of Stingray's
transportation revenue for the year ended December 31, 1995.  During the same
period, Texas Gas Transmission Corporation accounted for 24% of HIOS'
transportation revenue. Shell Trading, Tatham Offshore and United Meridian
Corporation accounted for 48%, 18% and 13%, respectively, of the transportation
revenue from LOGS during the year ended December 31, 1995.  Texaco Gas
Marketing, Inc., UNOCAL, Conoco, Inc. and Occidental USA accounted for 37%,
17%, 16% and 16%, respectively, of the transportation revenue from Green Canyon
for the year ended December 31, 1995.  Chevron, Oryx Energy Company and
Anadarko Trading Company accounted for 33%, 30% and 15%, respectively, of the
transportation revenue from Tarpon for the year ended December 31, 1995. Tatham
Offshore accounted for 100% of the transportation revenue from Ewing Bank and
POGO Gulf Coast Limited Producing Company accounted for 100% of the
transportation revenue from the Manta Ray system for the year ended December
31, 1995.  Shell, Delmar Operating, Inc. and Murphy Oil USA, Inc. accounted for
46%, 31% and 11%, respectively, of the transportation revenue of Viosca Knoll
System for the year ended December 31, 1995.  No other shipper on any of the
Pipelines accounted for more than 10% of any such Pipeline's revenue for 1995.

     The Pipelines transport gas under both firm and interruptible
transportation service agreements.  Under firm service agreements, a pipeline
is obligated to transport up to a specified maximum quantity of gas without
interruption, except upon occurrence of a force majeure event. Firm customers
generally pay a two part rate, a demand charge and a commodity charge.  The
demand charge is payable monthly based on the maximum contract quantity the
pipeline is obligated to transport, without regard to the quantity actually
transported during such month.  The commodity charge is payable monthly based
on the actual quantity of gas transported during such month.  Under
interruptible contracts, a pipeline is usually obligated to transport up to a
specified maximum quantity of gas, subject to availability of capacity, on a
first-come, 

                                      7


<PAGE>   10

first-served basis.  Interruptible customers pay only a one-part commodity rate
that includes both the demand and commodity elements of the firm rate. 
Stingray has historically provided transportation services under firm service
agreements.  However, following the expiration of Stingray's two most
significant firm transportation agreements in November 1994, substantially all
of Stingray's transportation service has been provided under interruptible
service agreements.

     Transportation, Processing and Platform Access Agreements with Tatham
Offshore.  The Partnership and Tatham Offshore have entered into
transportation, processing and platform access agreements pursuant to a Master
Gas Dedication Agreement by which Tatham Offshore has dedicated all production
from its Garden Banks, Viosca Knoll, Ewing Bank and Ship Shoal leases as well
as certain adjoining areas of mutual interest to the Partnership for
transportation.  In exchange, the Partnership has agreed to install certain
pipeline and related facilities necessary to transport production from the
areas and to provide transportation with respect to such production.
            
     Pursuant to the Master Gas Dedication Agreement, the Partnership
constructed the Ship Shoal Pipeline Extension and has refurbished and is
operating the SS 332 Platform to process production from Genuine Risk.  Each of
the three wells Tatham Offshore has drilled at Genuine Risk are currently
shut-in and not producing.

     In July 1992, the Partnership and Tatham Offshore entered into a firm gas
transportation agreement (the "Ewing Bank Gathering Agreement").  Pursuant to
the Ewing Bank Gathering Agreement and the Master Gas Dedication Agreement, all
existing and future oil and gas production from Tatham Offshore's leaseholds in
the Ewing Bank project area, which includes Ewing Bank Block 914 and seven
other contiguous Ewing Bank blocks, is dedicated to the Partnership for
transportation.

     The Ewing Bank Gathering Agreement remains in effect for the productive
life of the reserves or, if earlier, the expiration of 50 years from the date
of first production (August 1993).  Under the Ewing Bank Gathering Agreement,
the Partnership has agreed to provide future gathering facilities subject to
mutual agreement between the parties and the determination by the Partnership
that such facilities would be economic.  If pursuant to the Ewing Bank
Gathering Agreement additional gathering facilities are constructed by the
Partnership, the construction of such facilities would require Tatham Offshore
to pay additional demand charges and commodity charges.  See "-- Exploration
and Production -- Oil and Gas Properties -- Tatham Offshore's Oil and Gas
Properties -- Seattle Slew (Ewing Bank Blocks 914 and 915)."

     Production problems at Ship Shoal Block 331 and reduced oil production
from the Ewing Bank 914 #2 well affected Tatham Offshore's ability to pay the
demand charge obligations under agreements relative to these properties.  As a
result, effective February 1, 1996, the Partnership agreed to release Tatham
Offshore from all remaining existing demand charge payments under the
transportation agreements, a total of $17.8 million. Tatham Offshore remains
obligated to pay the commodity charges under these agreements as well as all
platform access and processing fees associated with the VK 817 Platform.  In
exchange, the Partnership received 7,500 shares of Tatham Offshore senior
preferred stock (the "Senior Preferred Stock").  Each share of the Senior
Preferred Stock has a liquidation preference of $1,000 per share, is senior in
liquidation preference to all other classes of Tatham Offshore stock and has a
9% cumulative dividend, payable quarterly.  Commencing on October 1, 1998 and
for a period of 90 days thereafter, the Partnership has the option to exchange
the remaining liquidation preference amount and accrued but unpaid dividends
for shares of Tatham Offshore's Series A 12% Convertible Exchangeable Preferred
Stock (the "Series A Preferred Stock") with an equivalent market value.
Further, the Partnership has made an irrevocable offer to Tatham Offshore to
sell all or any portion of the Senior Preferred Stock to Tatham Offshore or its
designee at a price equal to $1,000 per share, plus interest thereon at 9% per
annum less the sum of any dividends paid thereon.  The Series A Preferred Stock
is convertible into Tatham Offshore common stock based on a fraction, the
numerator of which is the liquidation preference value plus all accrued but
unpaid dividends and the denominator of $0.653 per share which was based on the
lowest average of consecutive five day closing prices for Tatham Offshore's
common stock between December 26, 1995 and July 1, 1996.  In addition, the
Partnership is entitled to recover an additional $7.5 million plus interest
from oil and gas properties obtained from Tatham Offshore.  See "-- Exploration
and Production -- General."  Tatham Offshore also agreed to grant the
Partnership the right to utilize the Ship Shoal Block 331 platform and related
facilities at a rental rate of $1.00 per annum for such period as the platform
is owned by Tatham Offshore and located on Ship Shoal Block 331, provided such
use does not interfere with 

                                      8


<PAGE>   11

lease operations or other activities of Tatham Offshore.  In addition, Tatham
Offshore granted the Partnership a right of first refusal relative to a sale of
the platform.

     Combined Manta Ray System.  On May 1, 1996, Manta Ray Gathering Systems
Inc. and Manta Ray Pipeline Holding Company, L.L.C. were merged with and into
Manta Ray, and the LOGS system and the Manta Ray system, and the respective
assets of such entities, were integrated to form the Combined Manta Ray System.

     As of December 31, 1995, the Partnership transported gas on the LOGS
system primarily under interruptible gas transportation agreements.  In
general, these agreements provide that the Partnership will transport up to a
specified maximum quantity of gas produced from lease blocks dedicated under
such agreements to specified points of delivery.   In return, the Partnership
receives transportation rates ranging from $0.03 to $0.20 per MMbtu (with a
weighted average of $0.075 per MMbtu for volumes transported for the year ended
December 31, 1995).  These agreements generally expire when production from the
lease blocks dedicated under such agreements ceases.
                            
     As of December 31, 1995, the Partnership transported gas on the Manta Ray
system under one interruptible service agreement.  The average rate applicable
to this gathering service is $0.042 per MMbtu. A portion of the system's
14-inch diameter line was placed in service in April 1996 and transports sour
crude oil from a connection with the Poseidon Oil Pipeline at Ship Shoal Block
332 to an interconnect with the Eugene Island Pipeline System at Ship Shoal
Block 207.  The Partnership receives a monthly fee from POPCO for the use of
this line.

     Green Canyon.  As of December 31, 1995, the Partnership transported gas on
the Green Canyon system under both firm and interruptible transportation
agreements.  In general, such agreements provide that the Partnership will
transport up to a specified maximum quantity of gas from various producing
platforms to South Marsh Island Block 106 in return for transportation fees
that currently range from $0.08 to $0.10 per MMbtu for gas actually
transported.  No demand charges are payable under these firm gas transportation
agreements.  With respect to the availability of pipeline capacity, shippers
transporting gas under these firm transportation contracts have priority over
gas shipped under interruptible contracts.  These agreements generally expire
when production from the lease blocks dedicated under such agreements ceases.

     Tarpon.  As of December 31, 1995, the Partnership transported gas on the
Tarpon system under interruptible service agreements and charged an average
rate of $0.068 per Mcf of gas transported. Tarpon's rates are currently subject
to FERC regulation.  See "-- Regulation -- Rate Cases -- Tarpon."

     Viosca Knoll System.  As of December 31, 1995, gas was being transported
on the Viosca Knoll System under two firm transportation agreements and four
interruptible transportation agreements and the average rate charged was $0.114
per MMbtu.  Gas reserves from a number of other fields, including the Shell
operated Ram-Powell field, are committed to the Viosca Knoll System.  These
agreements generally expire when production from the lease blocks dedicated
under such agreements ceases.

     Stingray.  The majority of the gas volume transported on the Stingray
system is currently transported under interruptible transportation agreements.
As of December 31, 1995, Stingray was a party to three firm transportation
agreements providing for transportation of up to 32 MMcf of gas per day, in the
aggregate, representing approximately 3% of Stingray's total capacity.  All of
the rates on the Stingray system are subject to FERC regulation.  See 
"-- Regulation -- Rate Cases -- Stingray."

     HIOS.  The majority of the gas volume transported on the HIOS system is
transported pursuant to interruptible transportation agreements.  However, as
of December 31, 1995, HIOS transported gas under two firm transportation
agreements providing for transportation of up to 190 MMcf of gas per day, in
the aggregate, representing approximately 11% of the maximum daily capacity of
HIOS.  All of the rates on the HIOS system are subject to FERC regulation.  See
"-- Regulation -- Rates Cases -- HIOS."

     UTOS.  As of December 31, 1995, the UTOS system transported gas under one
firm transportation agreement providing for transportation of up to 20 MMcf of
gas per day representing approximately 2% of UTOS' total capacity.  The
remainder of the gas volume transported on the UTOS system is transported
pursuant to interruptible transportation agreements.  The one firm contract
expired on January 1, 1996. 

                                      9


<PAGE>   12

However, the shipper continues to transport gas on the UTOS system under an
interruptible agreement.  All of the rates on the UTOS system are subject to
FERC regulation.  See "-- Regulation -- Rate Cases -- UTOS."

     COMPETITION

     Each of the Pipelines is located in or near natural gas production areas
that are served by other pipelines.  As a result, the Partnership's systems
face competition from both regulated pipelines and gathering systems with
respect to its transportation services.  Certain of these pipelines are not
subject to the same level of rate and service regulation as, and may have a
lower cost structure than, the Pipelines, and other pipelines, such as
long-haul transporters, have rate design alternatives unavailable to the
Pipelines. Consequently, such other pipelines may be able to provide service on
more flexible terms and at rates significantly below the maximum rates
permitted by the FERC to be charged by the Regulated Pipelines for comparable
services.  The Pipelines' principal interstate pipeline competitors are ANR,
Transco, Trunkline, Tenneco, Texas Eastern Transmission Corporation, Sea Robin
Pipeline Company, Columbia Gas Transmission Corporation and their affiliates.
The Pipelines compete for new production with these and other competitors on
the basis of geographic proximity to the production, cost of connection,
available capacity, transportation rates and access to onshore markets.  In
addition, the ability of the Pipelines to access future reserves will be
subject to the ability of the Pipelines or the producers to fund the anticipated
significant capital expenditures required to connect the new production. 
Several of the Pipelines' competitors are significantly larger and have more
capital resources available to them than do the Pipelines.             

     The Poseidon Oil Pipeline was built as a result of the Partnership's
belief that additional crude oil capacity was required to transport new subsalt
and deepwater oil production to shore.  Poseidon Oil Pipeline's principal
competitors for additional crude oil production are the Texaco operated Eugene
Island Pipeline System and the Shell operated Amberjack System.  The Poseidon
Oil Pipeline competes for new production with these and other competitors on
the basis of geographic proximity to the production, cost of connection,
available capacity, transportation rates and access to onshore markets.  In
addition, the ability of the Poseidon Oil Pipeline to access future reserves
will be subject to the ability of the Poseidon Oil Pipeline or the producers to
fund the anticipated significant capital expenditures required to connect the
new production.  Several of the Poseidon Oil Pipeline's competitors are
significantly larger and have more capital resources available to them than
does the Poseidon Oil Pipeline.

EXPLORATION AND PRODUCTION

     GENERAL

     DeepTech conducts exploration and production activities primarily through
Tatham Offshore and Flextrend Development Company, L.L.C. ("Flextrend
Development"), an Operating Company of the Partnership.  Tatham Offshore and
Flextrend Development are each independent energy companies engaged in the
development, exploration and production of reserves located primarily offshore
the United States in the Gulf, focusing principally on the Flextrend and
Deepwater areas. Tatham Offshore and Flextrend Development own, in the
aggregate, interests in 17 lease blocks in the Gulf comprising 94,720 gross
(82,580 net) acres.  As of June 30, 1996, Tatham Offshore's and Flextrend
Development's proved reserves were estimated to be 15.3 million barrels of oil
and 115.6 Bcf of gas in the aggregate based on reserve reports prepared by
Ryder Scott Company Petroleum Engineers ("Ryder Scott") and Netherland, Sewell
& Associates, Inc. ("Netherland, Sewell").  Ryder Scott, an independent
petroleum engineering consulting firm, prepared the reserve report for Tatham
Offshore and Netherland, Sewell, also an independent petroleum engineering
consulting firm, prepared the reserve report for Flextrend Development.  See
"-- Oil and Gas Reserves" for a discussion on the assumptions used in, and
inherent difficulties relating to, estimating reserves.

     As of August 30, 1996, DeepTech owned (i) 10,000,000 shares of Tatham
Offshore common stock representing approximately 39% of the issued and
outstanding common stock of Tatham Offshore and (ii) an indirect 23.2%
effective interest in Flextrend Development.  In addition, DeepFlex Services
owns 4,670,957 shares of Series A Preferred Stock and 5,329,043 Tatham Offshore
warrants and the Partnership owns 7,500 shares of Senior Preferred Stock of
Tatham Offshore.  The common stock of Tatham Offshore is traded on the Nasdaq
National Market ("Nasdaq") under the symbol "TOFF." The closing price of Tatham
Offshore's common stock on Nasdaq was $1 1/16 per share on August 30, 1996. The
Tatham 

                                      10


<PAGE>   13

Offshore warrants and Series A Preferred Stock are traded in the
over-the-counter market under the symbols "TOFFW" and "TOFFL," respectively.
       
     On June 30, 1995, Flextrend Development entered into a purchase and sale
agreement (the "Purchase and Sale Agreement") with Tatham Offshore pursuant to
which Flextrend Development acquired, subject to certain reversionary rights, a
75% working interest in Viosca Knoll Block 817, a 50% working interest in
Garden Banks Block 72 and a 50% working interest in Garden Banks Block 117 (the
"Assigned Properties") from Tatham Offshore for $30 million.  Flextrend
Development is entitled to retain all of the revenue attributable to the
Assigned Properties until it has received net revenue equal to the Payout
Amount (as defined below), whereupon Tatham Offshore is entitled to receive a
reassignment of the Assigned Properties, subject to reduction and conditions as
discussed below.  "Payout Amount" is defined as an amount equal to all costs
incurred by Flextrend Development with respect to the Assigned Properties
(including the $30 million acquisition cost paid to Tatham Offshore) plus
interest thereon at a rate of 15% per annum. Effective February 1, 1996, the
Partnership entered into an agreement with Tatham Offshore regarding certain
transportation agreements that increases the amount recoverable from the Payout
Amount by $7.5 million plus interest.  See "-- Transportation Services --
Customers and Contracts -- Transportation, Processing and Platform Access
Agreements with Tatham Offshore."  By adding $7.5 million to the Payout Amount,
the Partnership is entitled to an additional $7.5 million plus interest at the
rate of 15% per annum from revenue attributable to the Assigned Properties
prior to reconveying any interest in the Assigned Properties to Tatham
Offshore.  As of June 30, 1996, the Payout Amount balance was $77.7 million
comprised of (i) initial acquisition and transaction costs of $32.1 million,
(ii) developing and operating costs of $49.3 million, (iii) prepaid demand
charges of $7.5 million and (iv) interest of $7.1 million, reduced by net
revenue of $18.3 million. Tatham Offshore and the Partnership also agreed that
in the event Tatham Offshore furnishes the Partnership with a financing
commitment from a lender with a credit rating of BBB- or better covering 100% of
the then outstanding Payout Amount, the interest rate utilized to compute the
Payout Amount shall be adjusted from and after the date of such commitment to
the interest rate specified in such commitment, whether utilized or not.  As of
June 30, 1996, Flextrend Development had drilled, or was in the process of
drilling, a total of eight wells on Viosca Knoll Block 817 and a total of four
wells on Garden Banks Block 72.  In addition, Flextrend Development was in the
process completing the subsea tie-back of the Garden Banks Block 117 #1 well to
the Garden Banks Block 72 production platform.  At any time prior to December
10, 1996, Flextrend Development may exercise either of the following options
(the "Working Interest Options"): (i) to permanently retain 50% of the assigned
working interests in either the Viosca Knoll Block 817 property or the Garden
Banks Block 72/Garden Banks Block 117 properties or (ii) to permanently retain
50% of the assigned working interest in all Assigned Properties in exchange for
forgiving 25% or 50%, respectively, of the then-existing Payout Amount,
exclusive of the $7.5 million plus interest added to the Payout Amount in
connection with the restructuring of certain transportation agreements as
discussed above.  In the event Flextrend Development elects to reduce the Payout
Amount, it will become obligated to fund any further development costs
attributable to Tatham Offshore's portion of the working interests, such costs
to be added to the Payout Amount.  Otherwise, any further development costs will
be funded by Flextrend Development on a discretionary basis, such costs to be
added to the Payout Amount.  Further, in the event Flextrend Development forgoes
its right to permanently retain a working interest in all or a portion of the
Assigned Properties, it will be entitled to recover from working interest
revenues in respect of the Assigned Properties all future demand charges payable
for platform access and processing, in their inverse order of maturity, prior to
any reassignment to Tatham Offshore.  If however, Tatham Offshore (i) satisfies
in full the future demand charges payable for platform access and processing,
(ii) delivers evidence that is has received a rating of BBB-, or better, from at
least two reputable rating agencies or (iii) delivers evidence that an entity
with a rating of BBB-, or better, has agreed to guarantee, assume or, to the
reasonable satisfaction of the Partnership, otherwise become responsible for
such future demand charges payable, then Tatham Offshore would receive a
reassignment of the Assigned Properties upon satisfaction of the Payout Amount. 
In the event the Payout Amount has been satisfied but none of the above
conditions have been met, Tatham Offshore is entitled to receive one-third (1/3)
of the revenues, net of operating expenses and platform access and processing
fees, until such time as one of the above conditions is met.

     OIL AND GAS PROPERTIES

     The following is a description of the oil and gas properties in which
Flextrend Development and Tatham Offshore own an interest.  These properties
include producing properties and undeveloped leases.

     Flextrend Development's Oil and Gas Properties

     Viosca Knoll Block 817 (Phar Lap).  Phar Lap is a development project that
is comprised of approximately 5,760 gross acres located approximately 40 miles
off the coast of Louisiana in approximately 650 feet of water.  Pursuant to the
Purchase and Sale Agreement, Tatham Offshore assigned to Flextrend Development
a 75% working interest (56.25% net revenue interest) in Viosca Knoll Block 817,
subject to certain reversionary rights, except for Tatham Offshore's right,
title and interest below the stratigraphic equivalent of the base of the Tex
X-6 Sand.

     Flextrend Development, as operator, has concluded the drilling program and
has completed the drilling of eight natural gas wells on Viosca Knoll Block
817.  The Viosca Knoll Block 817 project is currently producing an aggregate of
approximately 90 MMcf of gas per day. The well deliverability from the Viosca
Knoll Block 817 project is in excess of 90 MMcf per day but is limited to such
amount by the production equipment currently located on the VK 817 Platform.
The production equipment is currently being upgraded which should allow the
total deliverability from the Viosca Knoll Block 817 project to increase to
approximately 125 MMcf per day.  From inception of production through June 30,
1996, the Viosca Knoll project has produced 6.7 Bcf of gas, net to Flextrend
Development's current 75% working interest. Netherland, Sewell estimates that
approximately 45.5 Bcf of proved gas reserves are attributable to Flextrend
Development's interest in the Viosca Knoll Block 817 project as of June
30,1996.  Production from the Viosca Knoll Block 817 is dedicated to the
Partnership for transportation through the Viosca Knoll System. See 
"-- Transportation Services -- The Pipelines -- Viosca Knoll System."  Pursuant
to the Purchase and Sale Agreement, Tatham Offshore will receive a reassignment
of at least a 37.5% working interest upon satisfaction of the Payout Amount.

     Garden Banks Block 72 (Spectacular Bid).  Garden Banks Block 72 covers
approximately 5,760 gross (2,880 net) acres and is located 120 miles off the
coast of Louisiana in approximately 550 feet of water. Tatham Offshore and
Midcon Exploration Company ("MidCon Exploration") jointly bought the Garden
Banks Block 72 lease in the August 1991 OCS lease sale for a joint bid of $3.7
million.  On June 30, 1995, Tatham Offshore assigned its 50% working interest
(approximately 40.2% net revenue interest) in Garden Banks Block 72 to
Flextrend Development, subject to certain reversionary rights.  MidCon
Exploration owns the remaining 50% working interest in Garden Banks Block 72.

     In May 1996, Flextrend Development placed on production two wells at
Garden Banks Block 72. Since the inception of production in June 1996, Garden
Banks Block 72 produced 25 MMcf of gas and 48,000 barrels of oil, net to
Flextrend Development's interest.  Netherland, Sewell estimates that
approximately 0.9 MMbls of proved oil reserves and 2.8 Bcf of proved gas
reserves are attributable to Flextrend Development's interest in the Garden
Banks Block 72 project as of June 30, 1996.  In September 1996, a third well
was placed on production.  The three wells are currently producing an average
of approximately 3,600 barrels of oil and 6.5 MMcf of gas per day.  Gas
production from Garden Banks Block 72 is being transported through the Stingray
system and the oil production is being transported through the Poseidon Oil
Pipeline.  Flextrend Development has drilled an additional well on Garden Banks
Block 72 which it is in the process of completing.  A fifth well is currently
planned for the field.  Pursuant to the Purchase and Sale Agreement, Tatham
Offshore will receive a reassignment of at least a 25% working interest upon
satisfaction of the Payout Amount.

     Garden Banks Block 117 (Spend A Buck). Garden Banks Block 117 covers 5,760
gross (2,880 net) acres adjacent to Garden Banks Block 72 and is located in
approximately 1,000 feet of water.  Tatham Offshore and MidCon Exploration
jointly acquired the Garden Banks Block 117 lease from Shell Offshore under a
farm-in arrangement.  The farm-in agreement provides that Shell Offshore
retains a 1/12 overriding royalty interest in Garden Banks Block 117 with an
option to convert the overriding royalty interest into a 30% working interest
after the property has produced 25 million net equivalent barrels of oil.  In
November 1994, Tatham Offshore announced that it had completed the drilling of
a new field discovery at Garden Banks Block 117.  The Garden Banks 117 #1 well
was flow-tested at a rate of approximately 10,500 barrels of oil and 11.9 MMcf
of gas per day.  On June 30, 1995, Tatham Offshore assigned its 50% working


                                      12


<PAGE>   15

interest (approximately 40.2% net revenue interest) in Garden Banks Block 117 to
Flextrend Development, subject to certain reversionary rights.  MidCon
Exploration owns the remaining 50% working interest in Garden Banks Block 117.
                                          
     In July 1996, Flextrend Development initiated production from the Garden
Banks 117 #1 well which is currently producing approximately 2,500 barrels of
oil, 5.0 MMcf of gas and 2,900 barrels of water per day.  Flextrend Development
is in the process of drilling a second well on the Garden Banks Block 117 lease
which, if successful, Flextrend Development intends to complete and place on
production during the fourth quarter of 1996.  Netherland, Sewell estimates
that approximately 2.5 MMbls of proved oil reserves and 4.9 Bcf of proved gas
reserves are attributable to Flextrend Development's interest in the Garden
Banks Block 117 project as of June 30, 1996.  Gas production from Garden Banks
Block 117 is transported on the Stingray system and oil production is
transported through the Poseidon Oil Pipeline.  Pursuant to the Purchase and
Sale Agreement, Tatham Offshore will receive a reassignment of at least a 25%
working interest upon satisfaction of the Payout Amount.

     Tatham Offshore's Oil and Gas Properties

     Ewing Bank Blocks 914 and 915 (Seattle Slew).  Tatham Offshore owns a 100%
working interest in the Seattle Slew field which is located in the Flextrend
area in a water depth of approximately 1,000 feet. Seattle Slew is the initial
development project in Tatham Offshore's Ewing Bank project area. The Ewing
Bank project area consists of eight OCS lease blocks which contain
approximately 46,000 gross acres and which Tatham Offshore believes contains
three development projects.

     In 1991, Tatham Offshore caused the Ewing Bank 914 #2 well to be drilled
which was later connected to the Partnership's Ewing Bank system.  The Ewing
Bank 914 #2 well, Tatham Offshore's first well on Seattle Slew, commenced
production in August 1993 from the PA-4 reservoir.  From the inception of
production through June 30, 1996, the Ewing Bank 914 #2 well has produced a
total of approximately 1.1 million barrels of oil and condensate and 3.1 Bcf of
gas.  Ryder Scott estimates that 0.7 Bcf of proved gas reserves and 319,000
barrels of proved oil reserves remain to be produced from the PA-4 reservoir as
of June 30, 1996.  Ryder Scott has assigned an additional 2.5 Bcf of proved gas
reserves and 1.8 MMbbls of proved oil reserves to three additional reservoirs
in the Ewing Bank 914 #2 well.  Tatham Offshore anticipates that the Ewing Bank
914 #2 well will need to be recompleted in one of the remaining proved
reservoirs during calendar 1997. The production from the Ewing Bank 914 #2 well
is transported through the Ewing Bank system to a platform where it is
separated, measured and re-delivered into third party pipeline systems for
transportation.  The Ewing Bank 914 #2 well is currently producing an average
of approximately 900 barrels of oil, 2.0 MMcf of gas and 1,600 barrels of water
per day. See Item 7. "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Liquidity and Capital Resources --
Tatham Offshore."

     All future production from the Seattle Slew field is dedicated to the
Partnership for transportation under the Ewing Bank Gathering Agreement.  Under
the Ewing Bank Gathering Agreement, the Partnership's obligation to construct
facilities to transport production from new wells is subject to the mutual
agreement of the parties and the Partnership's determination that such
facilities will be economic. See "-- Transportation Services -- Customers and
Contracts -- Transportation, Processing and Platform Access Agreements with
Tatham Offshore."

     West Delta Block 35 (Silent Beauty).  Silent Beauty is a producing field
located 10 miles off the coast of Louisiana in approximately 60 feet of water.
Silent Beauty was acquired by Tatham Offshore in the May 1992 OCS lease sale
for approximately $224,000 to drill for and produce remaining reserves in a
fault block of an abandoned field.  In late 1992, Tatham Offshore farmed-out
the property and retained a 38% working interest in the West Delta Block 35.
The #A-1 well began producing in July 1993 and the #A-9 well began producing in
March 1994.  From the inception of production through June 30, 1996, the Silent
Beauty field has produced 2.2 Bcf of gas and 22,000 barrels of oil, net to
Tatham Offshore's interest.  Ryder Scott estimates that Tatham Offshore's
interest in the West Delta Block 35 contained approximately 1.8 Bcf of proved
gas reserves and 20,000 barrels of proved oil reserves as of June 30, 1996.
The gas production from the West Delta 35 field is transported onshore through
an interstate pipeline system and the oil production is currently transported
onshore by barge.

<PAGE>   16

     Ewing Bank Blocks 958, 959, 1002 and 1003 (Sunday Silence). Tatham
Offshore owns a 100% working interest in the Sunday Silence field, a recently
discovered and currently undeveloped field that is comprised of 20,160 gross
and net acres and located approximately six miles south of the Seattle Slew
field in water depths ranging from 1,400 to 1,600 feet.  In July 1994, Tatham
Offshore completed the drilling of an exploratory well at Sunday Silence, the
Ewing Bank 958 #1 well. Logs and sidewall cores indicate that the Ewing Bank 958
#1 well contains approximately 380 feet of oil and gas pay.  The Ewing Bank 958
#1 well, which was drilled to a total measured depth of 17,600 feet, identified
pay zones in the Pliocene aged formations lying primarily at measured depths
between 10,000 and 15,000 feet.  Ryder Scott estimates that approximately 6.2
Bcf of proved gas reserves and 4.4 MMbbls of proved oil reserves are
attributable to Tatham Offshore's interest in the Ewing Bank 958 #1 well as of
June 30, 1996.

     Tatham Offshore completed drilling its second Sunday Silence well at Ewing
Bank Block 1003 in late September 1994 to delineate the field.  During October
1994, the Ewing Bank 1003 #1 delineation well was flow-tested at a rate of
approximately 8,700 barrels of oil and 5.4 MMcf of gas per day.  Ryder Scott
estimates that approximately 1.1 Bcf of proved gas reserves and 1.8 MMbbls of
proved oil reserves are attributable to Tatham Offshore's interest in the Ewing
Bank 1003 #1 well.

     Subject to obtaining financing or an appropriate joint venture partner,
Tatham Offshore anticipates that the initial two Sunday Silence wells and any
subsequent delineation wells will be reentered and completed for production
after the installation of a SPAR buoy production facility. Production from
Sunday Silence is dedicated to the Partnership under the Ewing Bank Gathering
Agreement.  See "-- Transportation Services -- Customers and Contracts."  See
Item 7.  "Management's Discussion and Analysis of Financial Condition and
Results of Operations -- Liquidity and Capital Resources -- Tatham Offshore."

     On November 28, 1995, a federal law was enacted that offers deepwater
royalty relief for all new federal leases located in 200 meters or greater of
water depth in the Gulf.  For leases obtained prior to November 28, 1995, the
relief provided for in the new law is not automatic but must be applied for
with the Secretary of Interior (or his delegate).  An applicant must
demonstrate that the proposed new production for which the royalty relief is
sought would not be economic to develop absent the royalty relief.  Tatham
Offshore filed an initial application in December 1995 but was advised in late
January 1996 that applications could not be accepted in advance of publication
of proposed interim regulations.  Proposed interim regulations implementing the
new law were published by the Minerals Management Service ("MMS") in May 1996.
Tatham Offshore is in the process of preparing its application for royalty
relief for the Sunday Silence project and anticipates filing such application
within the next 30 days.  Under the new legislation, a minimum of the first
52.5 million equivalent barrels of oil production from the Sunday Silence
project would be exempt from federal royalties if such relief is granted.
Tatham Offshore believes that if the requested royalty abatement is granted,
the resulting improved economics for the project will be sufficient to obtain
development financing or an industry farmout arrangement.  However, there can
be no assurance that Tatham Offshore will be granted the requested royalty
abatement, enter into a farmout or financing arrangement on favorable terms,
that the Sunday Silence field will be successfully developed or that production
will be initiated therefrom on a timely basis, if at all.

     Viosca Knoll Block 817 (Phar Lap).  Tatham Offshore was assigned a 100%
working interest in the leases covering the Phar Lap acreage in July 1993
pursuant to a farm-in agreement with Petrofina Delaware, Inc. and Fina Oil and
Chemical Company.  In October 1994, Tatham Offshore assigned a 25% working
interest in the Viosca Knoll Block 817 and certain contiguous leases to F-W Oil
Interest, Inc., J. Ray McDermott Properties, Inc. and J. Ray McDermott, Inc.
(collectively, the "Phar Deep Partners") in exchange for funding an exploratory
well on the Viosca Knoll Block 818.  Tatham Offshore has since assigned a 75%
working interest (56.25% net revenue interest) in the Phar Lap project to
Flextrend Development, subject to certain reversionary rights.  The Phar Lap
project consists of the Viosca Knoll Block 817 above the stratigraphic
equivalent of the base of the Tex X-6 Sand.

     In September 1995, Tatham Offshore, entered into an agreement the Phar
Deep Partners pursuant to which Tatham Offshore reacquired in the aggregate a
25% working interest in Viosca Knoll Blocks 772/773, 774, 817, 818 and 861 (the
"Subject Interests").  In return, Tatham Offshore (i) assumed all leasehold and
development obligations with respect to the Subject Interests and (ii) issued a
Convertible Production Payment (defined below) to each Phar Deep Partner.
Under the Convertible Production Payment, the Phar Deep Partners are entitled
in the aggregate to 25% of the proceeds from production attributable to the
Subject Interests (after deducting all leasehold operating expenses, including
platform 
                                      14


<PAGE>   17

access and processing fees) until the Phar Deep Partners have received
the aggregate sum of $16 million. At the option of the Phar Deep Partners, the
unrecovered portion of the Convertible Production Payment may be converted into
common stock of Tatham Offshore at a price of $8.00 per share.  Under certain
conditions, the Phar Deep Partners have the right to require DeepTech to
purchase the Convertible Production Payment for an amount equal to 50% of the
unrecovered portion thereof.  From the inception of production through June 30,
1996, the Viosca Knoll project has produced 2.2 Bcf of gas, net to Tatham
Offshore's current 25% working interest.  Ryder Scott estimates that
approximately 17.2 Bcf of proved gas reserves are attributable to Tatham
Offshore's current 25% working interest in the Viosca Knoll Block 817 project as
of June 30, 1996.  Pursuant to the Purchase and Sale Agreement, Tatham Offshore
will receive a reassignment of at least a 37.5% working interest upon
satisfaction of the Payout Amount. See "-- Flextrend Development's Oil and Gas
Properties -- Viosca Knoll Block 817 (Phar Lap)."
         
     Ship Shoal Block 331 (Genuine Risk).  The Genuine Risk project is located
approximately 75 miles off the coast of Louisiana in 370 feet of water.  Tatham
Offshore acquired the 5,278 gross acre lease in the OCS lease sale in August
1992 for approximately $224,000 and holds a 100% working interest therein.

     Tatham Offshore installed a drilling and production platform on Ship Shoal
Block 331 (the "Ship Shoal Platform") in February 1994.  Once the Ship Shoal
Platform was installed, Tatham Offshore drilled and completed two wells and
initiated production in July 1994. A third well was subsequently drilled and
completed.  The Partnership constructed the Ship Shoal Pipeline Extension to
transport production from such wells.  Production and completion problems have
caused each of the three wells at Genuine Risk to be shut-in.  In connection
with Tatham Offshore's assessment of its Ship Shoal Block 331 property and its
decision to seek a sale of all or a portion of such property, or a joint
venture partner, Tatham Offshore reduced its investment in its Ship Shoal Block
331 property by $8.0 million during the year ended June 30, 1996.  Prior to the
production problems, the Genuine Risk project produced 88 MMcf of gas and
31,500 barrels of oil.  Ryder Scott estimates that 24.4 Bcf of proved gas
reserves and 3.2 MMbbls of proved oil reserves are attributable to Tatham
Offshore's interest in Genuine Risk.

   Other Properties

     The Partnership owns an overriding royalty interest in the six lease block
Ewing Bank Unit operated by Tatham Offshore.  This override entitles the
Partnership to receive from approximately 3.56% to 5.34% (depending on the
water depth of the specific lease block) of the future gross revenue from
production from the Ewing Bank Unit, except for the Ewing Bank 914 #2 well, in
which the Partnership is entitled to receive 7.13% of the gross revenue from
production.  The Ewing Bank 914 #2 well is currently the only producing well in
the Ewing Bank Unit.  See "-- Transportation Services --  The Pipelines --
Ewing Bank Gathering Company."  For the year ended December 31, 1995, the
Partnership received royalties in the amount of $0.8 million from its
overriding royalty interest in the Ewing Bank 914 #2 well.  In addition to its
royalty interest in the Ewing Bank Unit, the Partnership owns certain other
minority interests in oil and gas leases which are not material to the business
of the Partnership.

     International Opportunities

     In August 1995, Tatham Offshore formed a wholly-owned subsidiary, Tatham
Offshore (Jersey) Ltd. ("TOJ"), to pursue certain international opportunities.
TOJ is in the process of attempting to obtain offshore concessions from the
government of Nigeria.  TOJ has entered into an agreement with an independent
oil and gas company that is also attempting to obtain offshore concessions from
the government of Nigeria.  If either TOJ or such independent oil and gas
company receives a concession from the government of Nigeria, the parties have
agreed to assign a 50% working interest in such property or properties to the
other party.  There are no assurances that TOJ will be granted a concession or
that the terms and conditions that would apply to a concession if granted would
be acceptable to TOJ.

     In February 1996, TOJ entered an agreement pursuant to which it received
an option to acquire up to 2,500,000 shares, a 12.5% equity interest in Gas
Participacoes Ltda. ("GASPART").  GASPART in turn owns a minority equity
interest (approximately 41.5%) in seven local natural gas distribution
companies in Brazil. The remaining equity interest in each local distribution
company is owned by Petrobras, the Brazilian state-owned oil company, and the
state government for the state in which its operations are conducted.  The
option 

                                      15


<PAGE>   18

is exercisable in whole or in part at a price of $1.35 per share plus interest
thereon from February 1996 at the London Interbank Offering Rate.  The option
expires during the third calendar quarter of 1997.
       
     Tatham Offshore has entered into a drilling arrangement (the "Drilling
Arrangement") with Sedco Forex Division of Schlumberger Technology Corporation
("Sedco Forex").  Under the terms of the Drilling Arrangement, Tatham Offshore
has certain options with respect to the use of the semisubmersible drilling
rig, the FPS Bill Shoemaker, in the Newfoundland Grand Banks Area, offshore
Canada.  These options include the use of the FPS Bill Shoemaker for the
drilling of a well prior to the deployment of the rig for a third party and the
use of the rig following the completion of the third party operations, subject
to certain consents and subject to availability.  The FPS Bill Shoemaker is
currently owned by an affiliate of DeepTech and operated by Sedco Forex under a
management agreement.  See "-- Contract Drilling Services -- Description of
Properties -- FPS Bill Shoemaker."

     OIL AND GAS GATHERING AND MARKETING

     Tatham Offshore and the Partnership have agreed to sell all of their oil
and gas production to Offshore Marketing on a month to month basis.  Offshore
Marketing has agreed to purchase such production at the platforms to which it
is delivered.  The agreements with Tatham Offshore and the Partnership
currently provide Offshore Marketing fees equal to 2% of the sales value of
crude oil and condensate and $0.015 per dekatherm of natural gas.  During the
year ended June 30, 1996, sales to Offshore Marketing from the Partnership and
Tatham Offshore totaled $43.6 million.

     For a discussion of certain transportation and gathering agreements to
which Tatham Offshore and Flextrend Development are a party, including the
Ewing Bank Gathering Agreement and the Master Gas Dedication Agreement, see "--
Transportation Services -- Customers and Contracts."

(1)  Gas volumes are stated at the legal pressure base of the state or area in
     which the reserves are located and at 60 degrees Fahrenheit.
(2)  Tatham Offshore's 25% working interest in Phar Lap is subject to a $16.0
     million Convertible Production Payment payable from 25% of the net
     proceeds from such interest.  See "- Tatham Offshore's Oil and Gas
     Properties - Viosca Knoll Block 817 (Phar Lap)."
(3)  The estimates relating to Flextrend Development were calculated without
     taking into consideration certain production costs (including platform
     access fees, demand charges and other rentals) that will be paid by
     Flextrend Development to the Partnership as production occurs in
     consideration for platform construction and installation costs incurred by
     the Partnership.

     In general, estimates of economically recoverable oil and natural gas
reserves and of the future net revenues therefrom are based upon a number of
variable factors and assumptions, such as historical production from the
subject properties, the assumed effects of regulation by governmental agencies
and assumptions concerning future oil and gas prices, future operating costs
and future plugging and abandonment costs, all of which may vary considerably
from actual results.  All such estimates are to some degree speculative, and
classifications of reserves are only attempts to define the degree of
speculation involved.  For these reasons, estimates of the economically
recoverable oil and natural gas reserves attributable to any particular group
of properties, classifications of such reserves based on risk of recovery and
estimates of the future net revenues expected therefrom, prepared by different
engineers or by the same engineers at different sites, may vary substantially.
The meaningfulness of such estimates is highly dependent upon the assumptions
upon which they are based.

     Furthermore, the wells at Garden Banks Block 72, Viosca Knoll Block 817,
Ewing Bank Block 914 and West Delta Block 35 have only been producing since May
1996, December 1995, August 1993 and July 1993, respectively, and, accordingly,
estimates of future production are based on this limited history. Estimates
with respect to proved undeveloped reserves that may be developed and produced
in the future are often based upon volumetric calculations and upon analogy to
similar types of reserves rather than upon actual production history.
Estimates based on these methods are generally less reliable than those based
on actual production history.  Subsequent evaluation of the same reserves based
upon production history will 

                                      17


<PAGE>   20

result in variations, which may be substantial, in the estimated reserves.  A
significant portion of Tatham Offshore's and Flextrend Development's reserves is
based upon volumetric calculations.  Further, Tatham Offshore's proved
undeveloped reserves will require substantial additional capital to develop and
produce.  There can be no assurance that Tatham Offshore will be able to finance
the development and production of such reserves.  See Item 7.  "Management's
Discussion and Analysis of Financial Condition and Results of Operations --
Liquidity and Capital Resources -- Tatham Offshore."
                      
     The following table sets forth as of June 30, 1996 the estimated future
net cash flows and the present value of estimated future net cash flows
discounted at 10% per annum from the production and sale of the proved
developed and undeveloped reserves attributable to Tatham Offshore's and
Flextrend Development's respective and combined interests in gas and oil
properties as of such date, as determined by Ryder Scott and Netherland, Sewell
in accordance with the requirements of applicable accounting standards, before

(1)  In preparing such estimates, Ryder Scott used prices of $19.27 per barrel
     of oil and $2.48 per Mcf of gas as of June 30, 1996, the weighted average
     prices that Tatham Offshore estimates it would have received, assuming
     production from all of its properties with proved reserves.
(2)  The estimates relating to Flextrend Development were calculated without
     taking into consideration certain production costs (including platform
     access fees, demand charges and other rentals) that will be paid by
     Flextrend Development to the Partnership as production occurs in
     consideration of platform construction and installation costs incurred by
     the Partnership.
(3)  In preparing such estimates, Netherland, Sewell used prices of $17.53 per
     barrel of oil and $2.295 per MMbtu of gas as of June 30, 1996, adjusted by
     lease for gravity and Btu content, transportation and marketing fees,
     regional posted price differences and gas price hedges in place.  The
     prices used by Netherland, Sewell represent weighted average prices
     Flextrend Development estimates it would have received, assuming
     production from all of its properties with proved reserves.

     In accordance with applicable requirements of the Securities and Exchange
Commission (the "Commission"), the estimated discounted future net revenues
from estimated proved reserves are based on prices and costs at fiscal year end
unless future prices or costs are contractually determined at such date. Actual
future prices and costs may be materially higher or lower.  Actual future net
revenues also will be

                                      18


<PAGE>   21
affected by factors such as actual production, supply and demand for gas and
oil, curtailments or increases in consumption by natural gas purchasers,
changes in governmental regulations or taxation and the impact of inflation on
costs.

     In accordance with methodology approved by the Commission, specific
assumptions were applied in the computation of the reserve evaluation
estimates.  Under this methodology, future net cash flows are determined by
reducing estimated future gross cash flows to Tatham Offshore and Flextrend
Development for oil and natural gas sales by the estimated costs to develop and
produce the underlying reserves, including future capital expenditures,
operating costs, transportation costs, royalty and overriding royalty burdens,
production payments and net profits interest expense on certain of Tatham
Offshore's and Flextrend Development's properties.

     Future net cash flows were discounted at 10% per annum to arrive at
discounted future net cash flows. The 10% discount factor used to calculate
present value is required by the Commission, but such rate is not necessarily
the most appropriate discount rate.  Present value of future net cash flows,
irrespective of the discount rate used, is materially affected by assumptions
as to timing of future oil and natural gas prices and production, which may
prove to be inaccurate.  In addition, the calculations of estimated net
revenues do not take into account the effect of certain cash outlays,
including, among other things, general and administrative costs, interest
expense and dividends.  The present value of future net cash flows shown above
should not be construed as the current market value as of June 30, 1996, or any
prior date, of the estimated oil and natural gas reserves attributable to
Tatham Offshore's or Flextrend Development's properties.

(1)  The components of production costs may vary substantially among

     factors, but generally include demand and commodity charges under
     transportation agreements, maintenance and repair, labor and
     utilities costs.

     The relationship between average prices per Mcf and its average production
costs depicted by the table above is not necessarily indicative of future
results of operations expected by Tatham Offshore or Flextrend Development.
Average production costs exceeded average sales prices for Tatham Offshore in
1995 due primarily to production problems experienced by the Ewing 914 #2 well
and the three wells at Genuine Risk.  See "-- Exploration and Production -- Oil

     ACREAGE

     The following table sets forth Tatham Offshore's and Flextrend
Development's respective developed and undeveloped oil and gas acreage as of
June 30, 1996.  Undeveloped acreage is considered to be those lease acres on
which wells have not been drilled or completed to a point that would permit the
production of commercial quantities of gas and oil, regardless of whether or
not such acreage contains proved reserves. Gross acres in the following table
refer to the combined number of acres in which a working interest is owned
directly by Tatham Offshore or Flextrend Development.  The number of net acres
is Tatham Offshore's or Flextrend Development's respective fractional ownership
of working interests in the gross acres.

     COMPETITION

     The exploration and production business is highly competitive.  Many
competitors have financial and other resources substantially in excess of those
available to Tatham Offshore and Flextrend Development and may, accordingly, be
better positioned to acquire and exploit prospects, hire personnel and market
production.  In addition, many of Tatham Offshore's and Flextrend Development's
larger competitors may be better able to withstand the effect of changes in
factors such as worldwide oil and natural gas prices and levels of production,
the cost and availability of alternative fuels and the application of
government regulations, which affect demand for oil and natural gas production
and are beyond the control of Tatham Offshore and Flextrend Development.

     There is also extensive competition in the market for gas and oil produced
by Tatham Offshore and Flextrend Development.  Increases in worldwide energy
production capability, decreases in energy consumption as a result of
conservation efforts, and the continued development of alternate energy sources
have brought about substantial surpluses in gas and oil supplies in recent
years resulting in substantial competition for the marketing of gas and oil.
As a result, there have been reductions in gas and oil prices and delays in
producing and marketing natural gas after it is discovered.  Changes in
government regulations relating to the production, transportation and marketing
of gas have also resulted in the abandonment by many pipelines of long-term
contracts for the purchase of gas, the development by gas producers of their
own marketing programs to take advantage of new regulations requiring pipelines
to transport natural gas for regulated fees and an increasing tendency to rely
on short-term sales contracts priced at spot market prices.  See "--
Regulation."

CONTRACT DRILLING SERVICES

   GENERAL

     DeepTech affiliates currently own an interest in two semisubmersible
drilling rigs, the FPS Laffit Pincay and the FPS Bill Shoemaker.  DeepTech
intends to conduct its future contract drilling services business through a
newly formed subsidiary, RIGCO North America, L.L.C. ("RIGCO").  In July 1996,
DeepTech obtained a commitment from Lehman Commercial Paper Inc. to underwrite
and syndicate a senior secured credit facility in an aggregate amount of up to
$55 million (the "Lehman Commitment"). The two-year facility is expected to
provide the funds necessary to allow RIGCO to acquire the FPS Bill Shoemaker
and to perform significant upgrades to the rig.  RIGCO intends to acquire the
FPS Laffit Pincay from DeepFlex Production Partners, L.P. ("DeepFlex
Partners"), an effective 50%-owned affiliate of DeepFlex Services, by assuming
certain rig related indebtedness owed to DeepFlex Services.  See Item 7.
"Liquidity and Capital Resources -- DeepTech -- Sources of Cash."

Description of Properties

     FPS Laffit Pincay.  DeepFlex Partners acquired the FPS Laffit Pincay from
the Company in March 1995 in a sealed bid auction for $29.3 million.  The FPS
Laffit Pincay is a second generation semisubmersible drilling rig identical in
size to a sister unit, the Penrod 72, that was successfully converted in 1988
by Placid Oil Company and subsequently utilized as a floating production system
in the Gulf and later offshore Brazil. The FPS Laffit Pincay was originally
acquired with the intent of converting the rig into a floating production
system to lease to producers in the Gulf.  However, recent shortages in the
worldwide semisubmersible rig fleet caused by increased demand have had a
significant impact on the rates charged by rig operators.  The increase in  rig
rates caused the Company to reevaluate its plans for its two semisubmersibles
and to focus on making the rigs available for contract drilling services.

     In January 1996,  DeepFlex Partners entered into an agreement with Sedco
Forex under which Sedco Forex has agreed to operate the FPS Laffit Pincay.
Sedco Forex is the second largest operator of semisubmersible rigs in the
world.  Sedco Forex is responsible for all aspects of operating and marketing
the rig, subject to agreed budgets and certain authorizations for new
contracts.  The agreement with Sedco Forex provides them with a management fee
and the recoupment of Sedco Forex's actual operating costs. The FPS Laffit
Pincay is currently under contract to Flextrend Development and MidCon
Exploration and is engaged in the drilling of the Garden Banks Block 117 #2
well.


                                      21


<PAGE>   24
     FPS Eddie Delahoussaye. The Company acquired the FPS Eddie Delahoussaye, a
second generation semisubmersible drilling rig, and an option (the "Wilrig
Option") to purchase an additional semisubmersible drilling rig from Wilrig AS
("Wilrig") in November 1994 by issuing promissory notes in the aggregate
principal amount of $11.0 million (the "Wilrig Notes") to Wilrig.  In addition,
Wilrig received warrants granting the right to exchange the principal and
interest outstanding under the Wilrig Notes for a maximum of 1,100,000 shares
of DeepTech common stock at a price of $10.00 per share. The Company
subsequently transferred the FPS Eddie Delahoussaye to DeepFlex Partners in
exchange for payment-in-kind indebtedness ("PIK Notes").

     In September 1995, DeepFlex Partners sold the FPS Eddie Delahoussaye to
Reading & Bates (U.K.) Limited ("Reading & Bates") for (i) $3.3 million in cash
and cash equivalents and  (ii) approximately 1.2 million shares of Reading &
Bates common stock.  DeepFlex Partners transferred the net sales proceeds
(including the Reading & Bates common stock which was immediately sold) to
DeepFlex Services to repay a portion of the PIK Notes previously issued to
DeepFlex Services.  The sale of the FPS Eddie Delahoussaye resulted in net
proceeds to the Company of approximately $18.0 million.

     FPS Bill Shoemaker.  In December 1995 the Company exercised the Wilrig
Option and acquired the Treasure Searcher, a semisubmersible drilling rig that
has been renamed the FPS Bill Shoemaker. The FPS Bill Shoemaker is a twin
pontoon, ten column second generation semisubmersible drilling rig capable of
drilling in up to 1,500 feet of water.  The vessel is an Aker H-3 modified
design built in 1976 as an accommodations unit, converted to a drilling unit in
1981, and upgraded in 1991.  Subject to obtaining necessary financing, an
extensive upgrade, repair and refurbishment program is planned to begin during
the fourth quarter of 1996.  Once the upgrade program is completed, the FPS
Bill Shoemaker is expected to be deployed offshore Canada and will be operated
and managed by Sedco Forex.

     The acquisition of the FPS Bill Shoemaker was made by Deepwater Drillers,
L.L.C. ("Deepwater Drillers") for $14.5 million.  At the time of the
acquisition, Deepwater Drillers was effectively owned 50% by a wholly-owned
subsidiary of DeepFlex Services and 50% by Highwood Partners, L.P. ("Highwood
Partners"). In order to fund the acquisition and related expenditures, the
Company issued promissory notes to Highwood Partners for an aggregate principal
amount of $7.6 million which funds were advanced to Deepwater Drillers.  As of
June 30, 1996, the Company acquired the remaining 50% of Deepwater Drillers
from Highwood Partners in exchange for $14.5 million in cash and notes.

     In September 1996, Tatham Offshore entered into the Drilling Arrangement
with Sedco Forex who operates the FPS Bill Shoemaker under a charter agreement.
The Drilling Arrangement includes the use of the FPS Bill Shoemaker and will
become effective upon the mobilization of the rig to Tatham Offshore's initial
location.  The initial contract term of the Drilling Arrangement is for 90 days
or, if sooner, the completion of Tatham Offshore's initial drilling operation
and the mobilization of the rig to another location.  Tatham Offshore may, at
its option, extend the initial contract term through (i) three successive one
well options or (ii) two successive one year terms.  Under the terms of the
Drilling Arrangement, Tatham Offshore has committed to pay Sedco Forex a
drilling rate of $70,000 per day with a standby rate of $66,700 per day.  As
security for its obligations under the Drilling Arrangement, Tatham Offshore is
required to post an irrevocable letter of credit or cash collateral of $6.3
million, which amount is equal to the aggregate operating day rate for the
contract term.  In the event that Tatham Offshore exercises its option to
extend the Drilling Arrangement, Tatham Offshore and Sedco Forex must agree
upon additional security for the extension period.

     During the term of the Drilling Arrangement, Tatham Offshore has the right
to sub-contract the rig to other operators.  If the rig is sub-contracted to
another operator, Tatham Offshore will receive the difference between the
sub-contract rate and the above agreed upon rates, if any.  The Drilling
Arrangement is conditioned upon the completion of a third party financing that
will fund certain improvements to the FPS Bill Shoemaker.  Sedco Forex has the
right to substitute a similar drilling rig for the FPS Bill Shoemaker in the
event the FPS Bill Shoemaker is unavailable due to a previously submitted bid
for work offshore Canada.  In the event Sedco Forex elects to carry out such rig
substitution, Tatham Offshore has (i) an option to use the FPS Bill Shoemaker in
the Newfoundland Grand Banks Area rather than the substitute rig to complete the
initial contract term prior to the use by the third party, subject to
availability, and subject to higher contract rates to account for the additional
costs incurred by Sedco Forex as a result of operations offshore Canada and (ii)
an additional option, upon completion of the third 

                                      22


<PAGE>   25

party work and subject to the use of the rig for certain other projects, to
contract to use the rig for the drilling of one well at the then prevailing
contract price.

MARKETING AND GAS PROCESSING

     Offshore Marketing, an 80%-owned subsidiary of DeepTech, was formed to
market the oil and gas production of Tatham Offshore, the Partnership and
third-party producers.

     Offshore Processors, an 85%-owned subsidiary of DeepTech, was formed to
allow the Company to take advantage of gas processing opportunities afforded it
as a result of its other activities and interests. Offshore Processors, in
partnership with an affiliate of NGPL, currently has processing arrangements
with major gas processors to process gas available to such partnership.  The
volume of gas for which Offshore Processors arranges processing varies monthly
depending on the relationship between the price for unprocessed gas and the
price for the constituent products resulting from processing.

GEOLOGICAL AND GEOPHYSICAL EXPLORATION TECHNOLOGY

     Dover Technology, Inc. ("Dover"), a 50%-owned affiliate of DeepTech,
possesses state-of-the-art exploration capabilities that include seismic
analysis technology (hydrocarbon and lithologic identification, amplitude
quantification and amplitude variation with offset), interactive seismic data
processing and interpretation (both 2-D and 3-D) and computerized petrophysical
analysis (log interpretation and reservoir analysis).  The use of 3-D seismic
surveys, computerized workstations and the integration and analysis of
geological, petrophysical and engineering data utilizing modern hardware,
software and interpretation techniques produces a more accurate and detailed
analysis of prospect opportunities than is available by using conventional
approaches. In particular, the use of modern technologies facilitates the
optimal placement of development wells, more clearly identifies elements of
prospect risk and aids in the prediction of geologic conditions and potential
reserves.

     Historically, Dover has provided services primarily to the Company.  Dover
has entered into service agreements with the Partnership and Tatham Offshore,
which expire on October 31, 1996, to provide services to such companies on a
first priority basis.

MANAGEMENT SERVICES TO THE SUBSIDIARIES

     DeepTech provides management, operational, financial, accounting and
administrative services to each of the Subsidiaries pursuant to management
agreements.  The management fees charged to the Subsidiaries are intended to
approximate the cost of resources allocated by DeepTech to each Subsidiary.
DeepTech's general and administrative overhead costs are charged to the
Subsidiaries through these management fees. Historically, management fees
payable by each Subsidiary during its developmental stage have been funded
through advances by DeepTech to each such Subsidiary, thereby reducing cash
available to DeepTech from management fees.  Leviathan, as general partner of
the Partnership, is entitled to reimbursement of all reasonable expenses
incurred by it or its affiliates for or on behalf of the Partnership by
Leviathan to DeepTech under a management agreement.  The Partnership and Tatham
Offshore were each charged an annual management fee equal to 40% of DeepTech's
unreimbursed overhead through October 31, 1995.  In addition, Dover, DeepFlex
Services and Offshore Marketing were charged 5.0%, 7.5% and 7.5%, respectively,
of DeepTech's unreimbursed overhead.  In November 1995, Dover began functioning
as a stand alone business unit with its own management and employees and
therefore terminated its management agreement with DeepTech.  Effective
November 1, 1995, DeepTech redetermined the level of services provided to each
of its subsidiaries and amended the management agreements with Leviathan,
Tatham Offshore, DeepFlex Services and Offshore Marketing to provide for an
annual management fee of 45.3%, 27.4%, 18.8% and 8.5%, respectively, of
DeepTech's overhead. During the year ended June 30, 1996, Leviathan charged the
Partnership $6,068,000 of fees payable to DeepTech pursuant to the terms of the
management agreement.  In addition, the management agreement also requires
Leviathan to compensate DeepTech for certain tax liabilities resulting from
additional taxable income allocated to Leviathan as a result of the
Partnership's offering of additional Preference Units and the investment of the
offering proceeds into construction projects. For the year ended June 30, 1996,
Leviathan charged the Partnership $964,000 to compensate DeepTech for this
additional allocated taxable income.  During the year ended June 30, 1996,
Tatham Offshore, DeepFlex Services, Dover and Offshore Marketing were charged
$4,436,000, $2,078,000, $242,000 and $1,138,000, respectively, under their
respective management agreements.  Only Leviathan, Tatham Offshore and Offshore



                                      23

Marketing have paid their management fees for the year ended June 30, 1996.
The remaining Subsidiaries, which provide DeepTech reimbursement of 18.8% of
its general and administrative overhead costs, did not make payments of
management fees to DeepTech during such period.

OTHER ASSETS OF DEEPTECH

     Ewing Bank Override.  DeepTech owns overriding royalty interests in the
six lease block Ewing Bank Unit, which is operated by Tatham Offshore.  The
overrides entitle DeepTech to receive from approximately 3.03% to 4.54%
(depending on the water depth of the specific lease block) of the future gross
revenues from production from the Ewing Bank Unit, except for production from
the Ewing Bank 914 #2 well.

     Tatham Offshore Affiliate Note.  On November 1, 1995, DeepTech agreed to
assume $1.7 million of Dover's account receivable from Tatham Offshore in
exchange for reducing Dover's payable to DeepTech under a line of credit
arrangement for a like amount.  DeepTech then converted the $1.7 million
account receivable from Tatham Offshore into an unsecured promissory note (the
"Tatham Offshore Affiliate Note") which bears interest at 14.5% per annum.
Interest on the Tatham Offshore Affiliate Note is payable quarterly, beginning
March 31, 1996.  The principal is due and payable in six monthly installments,
beginning on a date which is the earlier of (i) November 1, 1997 or (ii) the
last day of the calendar month in which Tatham Offshore receives proceeds from
the issuance of any preferred stock in an amount equal to or greater than $20.0
million.

     Tatham Offshore Subordinated Notes.  As of June 30, 1996, Tatham Offshore
had issued to DeepTech $60 million aggregate principal amount of Subordinated
Convertible Promissory Notes (the "Tatham Offshore Subordinated Notes").  The
Tatham Offshore Subordinated Notes bear interest at a rate of 11 3/4% per
annum, payable quarterly in arrears; provided, however, that effective July 1,
1997, interest shall accrue at a rate of 13% per annum.  The principal amount
of the Tatham Offshore Subordinated Notes is payable in seven equal annual
installments commencing August 1, 1999.  At any time after August 1, 1999,
Tatham Offshore may redeem in full, or may from time to time redeem in part,
the Tatham Offshore Subordinated Notes, without penalty or premium, upon 90
days' prior written notice to the holders thereof. The holders of the Tatham
Offshore Subordinated Notes have the option, at any time and from time to time,
to convert all or any portion of the principal and accrued interest outstanding
thereunder into common stock of Tatham Offshore at $10.00 per share, subject to
adjustment under certain circumstances.  The holders of 20% or more of the
principal amount of the Tatham Offshore Subordinated Notes and Tatham Offshore
common stock into which Tatham Offshore Subordinated Notes have been converted
have the right to demand the registration of the Tatham Offshore Subordinated
Notes (or any shares of Tatham Offshore common stock issued upon conversion
thereof) under the Securities Act; provided, however, that Tatham Offshore
shall only be obligated to file and cause to become effective three
registration statements with respect thereto.  In addition, such holders have
certain piggyback registration rights.  If DeepTech were to convert the entire
$60 million principal amount of Tatham Offshore Subordinated Notes into Tatham
Offshore common stock pursuant to such conversion right, DeepTech would own an
additional 6,000,000 shares of Tatham Offshore common stock.  DeepTech has no
present intention to exercise such conversion right.  The holders of a majority
of the aggregate principal amount of Tatham Offshore Subordinated Notes may
accelerate the payment of the principal and interest thereon upon the
occurrence of certain events of default which include the failure to pay
principal or interest when due, the voluntary or involuntary bankruptcy of
Tatham Offshore, an unpaid judgment against Tatham Offshore in excess of $5
million and the acceleration of other indebtedness of Tatham Offshore in excess
of $5 million in the aggregate.  The Tatham Offshore Subordinated Notes are
subordinate to all senior indebtedness of Tatham Offshore, which includes the
Tatham Offshore Affiliate Note.  Tatham Offshore has agreed not to incur
additional subordinated indebtedness without the consent of the holders of the
Tatham Offshore Subordinated Notes. DeepTech may only transfer the Tatham
Offshore Subordinated Notes after certain conditions are satisfied.

                                   REGULATION

     GENERAL

     The oil and gas industry is extensively regulated by federal and state
authorities in the United States. Legislation affecting the oil and gas
industry is under constant review and statutes are constantly being adopted,
expanded or amended.  Further, numerous departments and agencies, both federal
and state, have issued rules and regulations binding on the oil and gas
industry and its individual members, some of which carry substantial penalties
for the failure to comply.  The regulatory burden on the oil and gas industry
increases its cost of doing business.

     TRANSPORTATION, PIPELINES AND MARKETING

     General.  The design, construction, operation and maintenance by the
Pipelines of certain of their gas transmission facilities are subject to
regulation by the Department of Transportation under the Natural Gas Pipeline
Safety Act of 1968 as amended ("NGPSA").  Operations in offshore federal waters
are regulated by the Department of Interior and the FERC.  Under the Outer
Continental Shelf Lands Act ("OCSLA") as implemented by the FERC, pipelines
that transport natural gas across the OCS must offer nondiscriminatory
transportation of natural gas on behalf of others.  Substantially all of the
pipeline network owned by the Pipelines and POPCO is located in federal waters
in the Gulf, and the related rights-of-way were granted by the federal
government, the agencies of which oversee such pipeline operations.  Federal
rights-of-way require compliance with detailed federal regulations and orders
which regulate such operations.  See "-- Exploration, Production and
Development."

     The Poseidon Oil Pipeline is subject to regulation under the Hazardous
Liquid Pipeline Safety Act ("HLPSA").  Operations in offshore federal waters
are regulated by the Department of the Interior.  In addition, under OCSLA, as
implemented by the FERC, pipelines that transport crude oil across the OCS must
offer nondiscriminatory access to other potential shippers of crude.  The
Poseidon Oil Pipeline is located in federal waters in the Gulf, and its
right-of-way was granted by the federal government. Therefore, the FERC has
jurisdiction to compel POPCO to grant access under OCSLA to other shippers of
crude oil and to apportion the capacity of the line among owner and non-owner
shipper.

     Rates.  Each of the Regulated Pipelines (Tarpon, Stingray, HIOS and UTOS)
is classified as a "natural gas company" by the NGA.  Consequently, the FERC
has jurisdiction over the Regulated Pipelines with respect to transportation of
gas, rates and charges, construction of new facilities, extension or
abandonment of service and facilities, accounts and records, depreciation and
amortization policies and certain other matters.  In addition, the Regulated
Pipelines, where required, hold certificates of public convenience and
necessity issued by the FERC covering their facilities, activities and
services.

     Under the NGA and the Natural Gas Policy Act of 1978, as amended (the
"NGPA"), and the applicable FERC regulations, the Regulated Pipelines may not
charge or collect more than the maximum rates on file with the FERC.  FERC
regulations permit natural gas pipelines to charge maximum rates that generally
allow pipelines the opportunity to (i) recover operating expenses, (ii) recover
the pipeline's undepreciated investment in property, plant and equipment ("rate
base") and (iii) receive an overall allowed rate of return on the pipeline's
rate base.  The Partnership believes that even after the rate base of any
Regulated Pipeline is substantially depleted, the FERC will allow such
Regulated Pipeline to recover a reasonable return, whether through a management
fee or otherwise.

     None of Green Canyon, Ewing Bank, the Combined Manta Ray System or the
Viosca Knoll System is currently considered a "natural gas company" under the
NGA.  Consequently, these companies are not subject to extensive FERC
regulation under the NGA or the NGPA and are thus allowed to negotiate the
rates and terms of service with their respective shippers, subject to the
"equal access" requirements of the OCSLA, which requirements are administered
by the FERC.  The FERC has asserted its NGA rate jurisdiction over services
performed through gathering facilities owned by a natural gas company (as
defined in the NGA) when such services were performed "in connection with"
transportation services provided by such natural gas company.  Whether, and to
what extent, the FERC should exercise any NGA rate jurisdiction it may be found
to have over gathering facilities owned either by natural gas companies or
affiliates thereof is subject to case-by-case review by the FERC.  Based on
current FERC policy and precedent, the Partnership does not anticipate that the
FERC will assert or exercise any NGA rate 

                                      25


<PAGE>   28

jurisdiction over Green Canyon, Ewing Bank, the Combined Manta Ray System or the
Viosca Knoll system, so long as the services provided through such lines are not
performed "in connection with" transportation services performed through any of
the Regulated Pipelines.

Compliance filings by the Regulated Pipelines under FERC Orders 636, 636-A
and 636-B (collectively, "Order 636") have been made and, as amended, generally
have been fully implemented.  None of the Regulated Pipelines have ever
performed a merchant service and each already provides open-access
transportation as required by applicable FERC regulations.  Compliance with
Order 636 by the Regulated Pipelines has no material adverse effect on the
financial position or results of operations of the Partnership after its
implementation.

     The FERC has generally disclaimed jurisdiction to set rates for oil
pipelines in the OCS under the Interstate Commerce Act ("ICA").  Therefore,
unless the FERC's jurisdiction is invoked under OCSLA to remedy a denial of
non-discriminatory access, or the FERC reverses its decision that the ICA does
not apply to OCS oil pipelines, commencement of service on the Poseidon Oil
Pipeline will not subject it to rate regulation.

RATE CASES

     Tarpon.  Tarpon is currently operating under rates approved by the FERC in
an order issued February 4, 1993 which approved Tarpon's current rates
effective November 1, 1992.  Such order provides for a 2 1/2 year moratorium on
rate increases by Tarpon or complaints by its shippers subject to certain
exceptions that allow Tarpon to file to recover certain costs.  In addition,
after the first 12 months of the moratorium, Tarpon may file for a rate
increase if throughput levels fall below a certain level and its customers may
file a complaint with the FERC asking for a prospective rate reduction if
throughput exceeds a certain level. During 1994, Tarpon notified its shippers
that Tarpon's volumes were at a level that would allow such a complaint to be
filed in accordance with its settlement.  However, to date, no complaint has
been filed. Tarpon's rates contained two surcharges that terminated on March 31
and October 31, 1995, respectively.

     On May 28, 1992, Tarpon filed a petition requesting the FERC to declare
its offshore system to be a gathering facility exempt from the FERC's
jurisdiction and to vacate the order certificating the facilities. On July 20,
1992, the FERC denied Tarpon's petition.  Tarpon filed a request for rehearing
on November 17, 1992, and the FERC denied such request.  Tarpon appealed the
FERC's decision to the United States Court of Appeals for the District of
Columbia Circuit (the "D.C. Circuit") on November 20, 1992.  The proceedings
before the D.C. Circuit have been stayed pending action by the FERC with
respect to a motion filed by Tarpon on February 23, 1993 requesting the FERC
reopen and reconsider its orders rejecting Tarpon's petition, which motion was
renewed on June 25, 1996.  The renewal motion was opposed by one intervenor who
subsequently agreed to withdraw its opposition so that now Tarpon's motion is
unopposed. Such motion is pending before the FERC.

     Stingray.  On July 1, 1994, Stingray filed a rate case with the FERC under
Section 4 of the NGA to increase its previously approved rates.  This filing
was required because of the expiration on November 29, 1994, of Stingray's two
large firm contracts, which accounted for approximately 85% of Stingray's
contracted firm capacity, and the resulting loss of revenues attributable to
those firm contracts.  See "Business Operations -- Transportation Services --
Customers and Contracts -- Transportation Agreements."  By order issued October
11, 1995, the FERC approved a settlement of the rate case, pursuant to which
Stingray implemented new and final rates.  The Partnership has agreed to file a
new rate case with the FERC regarding these new rates in October 1998.

     HIOS.  In addition to its Order 636 compliance filing, HIOS filed a new
rate case on December 31, 1992 seeking to increase its rates over the rates
then in effect.  HIOS put into effect, subject to refund, rates in excess of
those previously authorized but lower than the rates it proposed.  On May 18,
1994, HIOS entered into a settlement of that rate case, which settlement was
approved by a FERC order dated July 20, 1994.  On March 1, 1994, HIOS filed a
new rate case seeking higher rates as a result of the expiration of most of its
firm contracts.  By order dated March 31, 1994, the FERC suspended HIOS'
proposed rate increase until September 1, 1994.  By order issued September 18,
1995, as modified by order issued October 16, 1995, the FERC approved a
settlement of the rate case, pursuant to which HIOS implemented new and final
rates effective December 1, 1995.  The Partnership has agreed to file a new
rate case with the FERC regarding these rates in December 1998.

     UTOS.  On March 1, 1994, UTOS filed a new rate case seeking higher rates
as a result of the expiration of most of its firm contracts.  By order dated
March 31, 1994, the FERC suspended UTOS' proposed rate increase until September
1, 1994.  By order issued September 18, 1995, as modified by order issued
October 16, 1995, the FERC approved a settlement of the rate case, pursuant to
which UTOS implemented new and final rates effective December 1, 1995.  The
Partnership has agreed to file a new rate case with the FERC regarding these
rates in December 1998.

     EXPLORATION, PRODUCTION AND DEVELOPMENT

     The exploration, production and development operations of the Company are
subject to regulation at the federal and state levels.  Such regulation
includes requiring permits for the drilling of wells and maintaining bonding
and insurance in order to drill or operate wells, and regulating the location
of wells, the method of drilling and casing wells, the surface use and
restoration of properties upon which wells are drilled and the plugging and
abandoning of wells.  Tatham Offshore's and the Partnership's exploration,
production and development operations are also subject to various conservation
laws and regulations.  These include the regulation of the size of drilling and
spacing units or proration units, the density of wells that may be drilled, the
levels of production, and the unitization or pooling of gas and oil properties.

     Substantially all of Tatham Offshore's and Flextrend Development's oil and
gas lease acreage was granted by the federal government and is being
administered by various federal agencies.  Such leases require compliance with
detailed federal regulations and orders that regulate, among other matters,
drilling and operations on these leases and calculation of royalty payments to
the federal government.  The Mineral Leasing Act of 1920 ("MLA") and similar
acts and regulations place limitations on the number of acres under federal
leases that may be owned in any one state.  The MLA and the OCSLA and related
regulations also may restrict a corporation from the holding of federal onshore
gas and oil leases if stock of such corporation is owned by citizens of foreign
countries that are not deemed reciprocal under such act. Reciprocity depends,
in large part, on whether the laws of the foreign jurisdiction prohibit or
otherwise restrict a citizen of the United States from owning minerals and/or
rights related thereto in such jurisdiction. The purchase of interests in the
Partnership by citizens of foreign countries who are not deemed to be
reciprocal under such Act could have an impact on Flextrend Development's
ownership of federal leases.

     Tatham Offshore and Flextrend Development presently collectively have
interests in or rights to offshore leases located in federal waters.  Federal
leases are administered by the MMS.  Individuals and entities must qualify with
the MMS prior to owning and operating any leasehold or right-of-way interest in
federal waters.  Such qualification with the MMS generally involves filing
certain documents with the MMS and obtaining an area-wide performance bond and,
in some cases, supplemental bonds representing security deemed necessary by the
MMS in excess of the area-wide bond requirements for facility abandonment and
site clearance costs.

     In August 1993, the MMS issued a final rule that addressed the new levels
of bond coverage required of OCS lessees in connection with the plugging and
abandoning of wells located offshore, the removal of all production facilities
and site clearance cots.  The coverage is designed to reflect an appropriate
balance between encouraging the maximum economic recovery of gas and oil from
federal offshore leases while providing the federal government an adequate
level of protection in the event the lessee defaults on its obligations to
properly abandon lease wells and remove platforms and other structures from the
property.

     Certain producing states, including Louisiana, have recently adopted or
considered adopting measures that alter the methods used to prorate gas
production from wells located in these states, including those in their
territorial waters.  These measures may limit the rate at which gas may be
produced from the wells in which the Company might acquire an interest.
Congress recently considered, but rejected, legislation that would have limited
the states' rights to prorate production.  The Company cannot predict whether
such legislation will be reintroduced or what effect the new state rules may
have on gas production in producing states.  At the present time there are no
allowables which would limit the production of oil or gas leases in which the
Company presently owns an interest.

     Pipeline Maintenance

     Each of the Pipelines and the Poseidon Oil Pipeline requires regular and
thorough maintenance.  The interior of the pipelines are maintained through the
regular "pigging" of the lines.  Pigging involves propelling through the line a
large spherical object which collects, or pushes, any condensate and other
liquids on the walls or at the bottom of the pipeline through the line out the
far end.  More sophisticated pigging devices include those with scrapers,
brushes and x-ray devices; however, such pigging devices are usually deployed
only on an as needed basis. On a continual basis, corrosion inhibitors are
injected into all of the systems through the gas stream.  To prevent external
corrosion of the pipe, sacrificial anodes are fastened to the pipeline itself
at prescribed intervals, providing exterior corrosion protection from sea
water. The platforms are painted to the waterline every three to five years to
prevent atmospheric corrosion. Sacrificial anodes are also fastened to the
platform legs below the waterline to prevent corrosion.  A sacrificial anode is
a zinc aluminum alloy fixture that is attached to the exterior of a steel
object to attract the corrosive reaction that occurs between steel and
saltwater to the fixture itself, thus protecting the steel object from
corrosion.  Remote operated vehicles or divers inspect the platforms below the
waterline usually every five years.

     The Stingray and HIOS systems, the Viosca Knoll System, the Poseidon Oil
Pipeline and the Combined Manta Ray System, include platforms that are manned
on a continuous basis.  The personnel onboard the platforms are responsible for
site maintenance, operations of the facilities on the platform, measurement of
the gas stream at the source of production and corrosion control (pig launching
and inhibitor injection).

                                 ENVIRONMENTAL

     General.  The Company's operations are subject to extensive federal, state
and local regulatory requirements relating to environmental affairs, health and
safety, waste management and chemical products. To the best of the Company's
knowledge, its operations are in substantial compliance, and are expected to
continue to comply in all material respects, with applicable environmental
laws, regulation and ordinances.

     It is possible, however, that future developments, such as stricter
environmental laws, regulations or enforcement policies could affect the
handling, manufacture, use, emission or disposal of substances or wastes by the
Company.  Moreover, some risk of environmental costs and liabilities is
inherent in the Company's operations and products as it is with other companies
engaged in similar or related businesses, and there can be no assurance that
material costs and liabilities, including substantial fines and criminal
sanctions for violation of environmental laws and regulations, will not be
incurred by the Company.  In connection with Leviathan's acquisition of its
interests in LOGS, Green Canyon, HIOS and UTOS, Transco agreed to indemnify
Leviathan through 1999 for environmental claims arising out of incidents which
occurred prior to July 1992.  Leviathan intends, to the extent possible, to
transfer to the Partnership the benefit of any rights arising under such
indemnification.

     Pipeline Transportation.  In addition to the NGA, the NGPA and the OCSCA,
several federal and state statutes and regulations may pertain specifically to
the operations of the Pipelines.  The Hazardous Materials Transportation Act,
as amended, regulates materials capable of posing an unreasonable risk to
health, safety and property when transported in commerce.  The NGPSA and the
HLPSA authorize the development and enforcement of regulations governing
pipeline transportation of natural gas and hazardous liquids.  While federal
jurisdiction is exclusive over regulated pipelines, the statutes allow states
to impose additional requirements for intrastate fines if compatible with
federal programs.  Both Texas and Louisiana have developed regulatory programs
that parallel the federal program for the transportation of natural gas by
pipelines.

     Solid Waste.  The Company's operations may generate or transport both
hazardous and nonhazardous solid wastes that are subject to the requirements of
the federal Resource Conservation and Recovery Act and comparable state
statutes.  Further, it is possible that some wastes that are currently
classified as nonhazardous, perhaps including wastes currently generated during
pipeline operations, may, in the future, be designated as "hazardous waste,"
which are subject to more rigorous and costly disposal requirements. Such
changes in the regulations may result in additional expenditures or operating
expenses by the Company.


                                      28


<PAGE>   31

     Hazardous Substances.  The Comprehensive Environmental Response,
Compensation and Liability Act ("CERCLA") and comparable state statutes, also
known as "Superfund" laws, impose liability, without regard to fault or the
legality of the original conduct, on certain classes of persons that
contributed to the release of a "hazardous substance" into the environment.
These persons include the owner or operator of a site, and companies that
transport, dispose of or arrange for the disposal of, the hazardous substances
found at the site.  CERCLA also authorizes the EPA, and in some cases, third
parties to take actions in response to threats to the public health or the
environment and to seek to recover from the responsible classes of persons the
costs they incur. Despite the "petroleum exclusion" of Section 101 (14) that
encompasses natural gas, the Company may generate or transport "hazardous
substances" within the meaning of CERCLA, or comparable state statutes, in the
course of its ordinary operations.  Thus, the Company may be responsible under
CERCLA or the state equivalents for all or part of the costs required to cleanup
sites where a release has occurred.

     Air.  The Company's operations may be subject to the Clean Air Act ("CAA")
and comparable state statutes.  Amendments to the CAA were adopted in 1990 and
contain provisions that may result in the gradual imposition of certain
pollution control requirements with respect to air emissions from operations.
The Environmental Protection Agency (the "EPA") and the states have been
developing regulations to implement these requirements.  The Company may be
required to incur certain capital expenditures in the next several years for
air pollution control equipment in connection with maintaining or obtaining
operating permits and approvals addressing other air emission-related issues.
However, the Company does not believe its operations will be materially
adversely affected by any such requirements.

     Water.  The Federal Water Pollution Control Act ("FWPCA") imposes strict
controls against the unauthorized discharge of produced waters and other oil
and gas wastes into navigable waters.  The FWPCA provides for civil and
criminal penalties for any unauthorized discharges of oil and other hazardous
substances in reportable quantities and along with the Oil Pollution Act of
1990 (the "OPA"), imposes substantial potential liability for the costs of
removal, remediation and damages.  Similarly, the OPA imposes liability for the
discharge of oil into or upon navigable waters or adjoining shorelines.  Among
other things, the OPA raises liability limits, narrows defenses to liability
and provides more instances in which a responsible party is subject to
unlimited liability.  One provision of the OPA requires that offshore
facilities establish and maintain evidence of financial responsibility of $150
million.  State laws for the control of water pollution also provide varying
civil and criminal penalties and liabilities in the case of a unauthorized
discharge of petroleum or its derivatives into state waters.  Further, the
Coastal Zone Management Act authorizes state implementation and development of
programs of management measures for nonpoint source pollution to restore and
protect coastal waters.

     Endangered Species.  The Endangered Species Act ("ESA") seeks to ensure
that activities do not jeopardize endangered or threatened plant and animal
species, nor destroy or modify the critical habitat of such species.  Under the
ESA, exploration and production operations, as well as actions by federal
agencies, may not significantly impair or jeopardize the species or its
habitat.  The ESA provides for criminal penalties for willful violations of the
Act.  Other statutes which provide protection to animal and plant species and
thus may apply to the Company's operations are the Marine Mammal Protection
Act, the Marine Protection and Sanctuaries Act, the Fish and Wildlife
Coordination Act, the Fishery Conservation and Management Act, the Migratory
Bird Treaty Act and the National Historic Preservation Act.

                       OPERATIONAL HAZARDS AND INSURANCE

     A pipeline may experience damage as a result of an accident or other
natural disaster.  The Company's exploration, production and development
operations are subject to the usual hazards incident to the drilling and
production of natural gas and crude oil, such as blowouts, cratering,
explosions, uncontrollable flows of oil, natural gas or well fluids, fires,
pollution, releases of toxic gas and other environmental hazards and risks.
These hazards can cause personal injury and loss of life, severe damage to and
destruction of property and equipment, pollution or environmental damages and
suspension of operations.  To mitigate the impact of repair costs associated
with such an accident or disaster, the Company maintains insurance of various
types that it considers to be adequate to cover its operations.  Such insurance
is subject to deductibles that the Company considers reasonable and not
excessive.  The Company's insurance does not cover every potential risk
associated with the drilling and production of oil and natural gas.  Consistent
with insurance coverage generally available to the industry, the Company's
insurance policies do not provide coverage for losses or liabilities relating
to pollution, except for sudden and accidental occurrences.



                                      29


<PAGE>   32
     The occurrence of a significant event not fully insured or indemnified
against, or the failure of a party to meet its indemnification obligations,
could materially and adversely effect the Company's operations and financial
condition.  Moreover, no assurance can be given that the Company will be able
to maintain adequate insurance in the future at rates it considers reasonable.

                                  ENCUMBRANCES

     Encumbrances Relating to the Senior Notes.  On March 21, 1994, DeepTech

Partnership credit agreement, as amended and restated, is a revolving credit
facility with a syndicate of commercial banks which provides the Partnership a
maximum $220 million of available credit in the form of a $145 million
revolving credit facility and $75 million term loan facility (the "Partnership
Credit Facility").  The Partnership Credit Facility is guaranteed by Leviathan
and each of the Operating Companies and Tarpon, and is secured by Leviathan's
1% general partner interest in the Partnership, all of Leviathan's and the
Partnership's interests in the Operating Companies and Tarpon, and
substantially all of the equipment, negotiable instruments and inventory and
other personal property of the Operating Companies and Tarpon.  See Item 7.
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources -- Leviathan/The Partnership."

     Encumbrances Relating to the Highwood Notes.  In December 1995, the
Company issued promissory notes to Highwood Partners (the "Highwood Notes") for
an aggregate principal amount of $13.5 million for the purchase of the FPS Bill
Shoemaker. In connection with the caretakership and refurbishment of the FPS
Bill Shoemaker and FPS V's purchase of Highwood Partners' 50% interest on June
30, 1996, the Company issued an additional $3.8 million of Highwood Notes.  The
Highwood Notes are secured by a mortgage on the FPS Bill Shoemaker and
approximately $3.0 million of PIK Notes, bear interest at 12%, payable
quarterly and are due March 31, 1997.  In July 1996, the Company borrowed an
additional $1.0 million for refurbishment costs bringing the total amount of
outstanding Highwood Notes to $18.3 million.  In connection with the issuance
of the Highwood Notes, the Company granted Highwood Partners warrants, which
expire on December 5, 1997, to acquire 472,973 shares of DeepTech common stock
at $5.00 per share.  See Item 7. "Management's Discussion and Analysis of
Financial Condition and Results of Operations -- Liquidity and Capital
Resources -- DeepTech."

     Encumbrances Relating to the Term Loan.  In February 1996, DeepFlex
Services entered into a term loan agreement to borrow $12.0 million (the "Term
Loan") from a syndicate of commercial lenders.  The Term Loan bears interest at
12% per annum, payable monthly, is due on July 15, 1997 and is secured by
substantially all tangible and intangible assets currently owned by DeepFlex
Services, including 5,329,043 Tatham Offshore warrants, 4,670,957 shares of
Series A Preferred Stock and all PIK Notes issued by DeepFlex Partners, except
the $3.0 million of PIK Notes pledged to Highwood Partners.  In addition, the



                                      30


<PAGE>   33

lenders required an assignment by DeepFlex Services of the first preferred ship
mortgage on the FPS Laffit Pincay which is securing the PIK Notes.  In
connection with the Term Loan, DeepTech issued to the lenders warrants to
purchase an aggregate of up to 2,666,667 shares of DeepTech common stock at
$4.50 per share. DeepFlex Services is required to make monthly principal
payments equal to its excess cash flow as defined in the Term Loan agreement
beginning in October 1996.  See Item 7.  "Management's Discussion and Analysis
of Financial Condition and Results of Operations -- Liquidity and Capital
Resources -- DeepTech."               

                                   EMPLOYEES

     As of June 30, 1996, DeepTech had 52 employees. DeepTech has entered into
management agreements with each of the Subsidiaries pursuant to which DeepTech
provides certain services, including operational, financial, accounting and
administrative services. The aggregate fees payable under these agreements
provide reimbursement for a substantial portion of DeepTech's general and
administrative expenses.  See Item 7.  "Management's Discussion and Analysis of
Financial Condition and Results of Operations -- Liquidity and Capital
Resources -- DeepTech."

                              CERTAIN DEFINITIONS

     The following are abbreviations and words commonly used in the oil and gas
industry and in this Annual Report.

     "3-D seismic" means seismic that is run, acquired and processed to yield a
three-dimensional picture of the subsurface.

     "bbl" or "barrel" means barrel, a standard measure of volume for oil,
condensate and natural gas liquids which equals 42 U.S. gallons.

     "Bcf" means billion cubic feet (or thousand MMcf).

     "Btu" means British thermal unit, a unit of heat measure with one btu
being the amount of heat needed to raise the temperature of one pound of water
one degree Fahrenheit.

     "condensate" means a hydrocarbon mixture that becomes liquid and
separates, similar to crude oil, from natural gas when it is produced.

     "development well" means a well drilled within the proved area of an oil
or gas reservoir to the depth of a stratigraphic horizon known to be
productive.

     "exploratory well" means a well drilled to find commercially productive
hydrocarbons in an unproved area or to extend significantly a known oil or
natural gas reservoir.

     "farm-in" or "farm-out" refers to an agreement whereunder 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 after payout in the lease.  The
assignor is said to have "farmed-out" the acreage.  The assignee is said to
have "farmed-in" the acreage.

     "gathering system" means a pipeline system connecting a number of wells,
batteries or platforms to an interconnection with an interstate pipeline.

     "gross" oil and natural gas wells or "gross" acres are the total number of
wells or acres, respectively, in which the Company has an interest, without
regard to the size of that interest.

     "Mbbl" means thousand barrels.

     "Mcf" means thousand cubic feet, a standard measure of volume for gas.

                                      31


<PAGE>   34


     "MMbbls" means million barrels.

     "MMbtu" means million British thermal units.

     "MMcf" means million cubic feet.

     "net" oil and natural gas wells or "net" acres are the total gross number
of wells or acres, respectively, in which the Company has an interest
multiplied times the Company's working interest in such wells or acres.

     "OCS" means Outer Continental Shelf, an area offshore the United States
over which the federal government has jurisdiction, which extends from the end
of state territorial waters (three to nine nautical miles offshore, depending
on the state) to 200 nautical miles from shore.  The term OCS as used herein
includes not only those areas on the Shelf itself, but those areas in the
Flextrend and the Deepwater, to a limit of 200 nautical miles, as well.

     "recompletion" means the completion of an existing well for production
from a formation that exists behind the casing of the well.

     "royalty" means an interest in an oil and gas lease that gives the owner
of the interest the right to receive a portion of the production from the
leased acreage (or of the proceeds of the sale thereof), but generally does not
require the owner to pay any portion of the costs of drilling or operating the
wells on the leased acreage.  Royalties may be either landowner's royalties,
which are reserved by the owner of the leased acreage at the time the lease is
granted, or overriding royalties, which are usually carved from the leasehold
interest pursuant to an assignment to a third party reserved by an owner of the
leasehold in connection with a transfer of the leasehold to a subsequent owner.

     "working interest" means an interest in an oil and gas lease that gives
the owner of the interest the right to drill for and produce oil and gas on the
leased acreage and requires the owner to pay a share of the costs of drilling
and production operations.  The share of production to which a working interest
owner is entitled will always be smaller than the share of costs that the
working interest owner is required to bear, with the balance of the production
accruing to the owners of royalties.  For example, the owner of a 100% working
interest in a lease burdened only by a landowner's royalty of 12.5% would be
required to pay 100% of the costs of a well but would be entitled to retain
87.5% of the production.

     In this Annual Report, natural gas volumes are stated at the legal
pressure base of the state or area in which the reserves are located and at 60
degrees Fahrenheit.

ITEM 2. PROPERTIES

     Information on properties of the Company is included in Item 1.
"Business."

ITEM 3. LEGAL PROCEEDINGS

     The Company is involved in certain other legal proceedings that have
arisen in the ordinary course of business, including various rate cases and
other proceedings before the FERC.  See "-- Regulation -- Transportation,
Pipelines and Marketing."  It is the opinion of management that the disposition
of the Company's pending legal proceedings will not individually or in the
aggregate have a material adverse effect on the Company.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

     No matters were submitted to a vote of the security holders of the Company
during the fourth quarter of fiscal year 1996.

     Thomas P. Tatham has served as Chairman of the Board, Chief Executive
Officer and a Director of DeepTech since October 1989 and as Chairman of the
Board and a Director of Leviathan since February 1989.  Mr. Tatham served as
Chief Executive Officer of Leviathan from February 1989 through June 1995 and
has served as Chairman of the Board of Tatham Offshore since its inception in
1988. Mr. Tatham has over 25 years experience in the oil and gas industry.  He
founded Mid American Oil Company in 1970 and served as Chairman of the Board
and Chief Executive Officer until he sold his interest therein to Centex
Corporation in 1979.  In 1979, Mr. Tatham founded Tatham Corporation to acquire
Sugar Bowl Gas Corporation ("Sugar Bowl"), the second largest intrastate
pipeline system in Louisiana.  He served as Chairman of the Board of Tatham
Corporation from 1979 to December 1983, at which time it sold the assets of
Sugar Bowl to a joint venture between MidCon Corp. and Texas Oil and Gas, Inc.
From 1984 to 1988, Mr. Tatham pursued personal investments in various
industries, including the oil and gas industry.  Mr. Tatham serves as a director
of J. Ray McDermott S.A.

- ---------------

(1)  Consisted of the period from the date on which DeepTech's common stock
     was first listed on Nasdaq, May 16, 1994 through June 30, 1994, a 46 day
     period.

     DeepTech has never paid cash dividends on its common stock and does not
contemplate that it will pay any cash dividends on its common stock in the
foreseeable future.  The payment of future dividends will be determined by
DeepTech's Board of Directors in light of conditions then existing, including
DeepTech's earnings, financial condition, capital requirements, restrictions in
financing agreements, business conditions and other factors.  DeepTech is a
holding company whose material assets consist primarily of stock of the
Subsidiaries.  Consequently, DeepTech's ability to pay dividends is dependent
upon management fees paid to it pursuant to management agreements with each of
the Subsidiaries, quarterly dividends funded by distributions from the
Partnership or from other Subsidiaries and interest on and repayment of debt by
the Subsidiaries.  Further, the Senior Notes Indenture includes covenants that
restrict the circumstances under which DeepTech may pay dividends.  Pursuant to
such covenants, DeepTech is currently prohibited from paying dividends or
making other distributions in respect of its common stock.

ITEM 6. SELECTED FINANCIAL DATA

                      SELECTED CONSOLIDATED FINANCIAL DATA

     The selected consolidated financial data set forth below for the Company
for each of the three fiscal years ended June 30, 1994, 1995 and 1996 and at
June 30, 1995 and 1996 have been derived from the historical consolidated
financial statements and notes thereto that are included elsewhere in this
Annual Report.  The consolidated financial data at June 30, 1992 and 1993 and
for the years then ended and at June 30, 1994 have been derived from the
historical consolidated financial statements.  The following selected
consolidated financial data of the Company should be read in conjunction with
the Company's consolidated financial statements and related notes thereto,
which are included elsewhere in this Annual Report. As a result of the
completion of Tatham Offshore's initial public offering (the "Tatham Offshore
Offering"), the results of operations of Tatham Offshore are not consolidated
in the Company's financial statements after February 14, 1994 and DeepTech
accounts for its investment in Tatham Offshore using the equity method.

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

     The following discussion should be read in conjunction with the Company's
consolidated financial statements and notes thereto included elsewhere in this
Annual Report.

GENERAL

     OVERVIEW.  DeepTech is a diversified energy company engaged, through the
Subsidiaries, in offshore contract drilling services and the acquisition,
development, production, processing, transportation and marketing of, and the
exploration for, oil and gas located primarily offshore the United States in
the Gulf, with principal focus in the Flextrend and Deepwater areas.  As a
holding company whose material assets consist primarily of stock of the
Subsidiaries, DeepTech is, and expects to continue to be, dependent upon
management fees, dividends funded by distributions from the Partnership and
interest on and repayment of principal under borrowings by the Subsidiaries to
pay its operating expenses, service its debt and satisfy its other obligations.

     The following discussion is intended to assist in the understanding of the
Company's financial position and results of operations for each of the fiscal
years ended June 30, 1996, 1995 and 1994.  See Item 6. "Selected Consolidated
Financial Data" and the consolidated financial statements and notes thereto
included elsewhere in this Annual Report for information that should be
referred to in conjunction with this discussion.  As a result of the completion
of the Tatham Offshore Offering, the results of operations of Tatham Offshore
are not consolidated in the Company's financial statements after February 14,
1994. Commencing February 15, 1994, DeepTech accounted for its investment in
Tatham Offshore using the equity method of accounting.

     LEVIATHAN AND THE PARTNERSHIP.  Leviathan serves as the general partner of
the Partnership and currently owns a 27.3% effective interest in the
Partnership (23.2% effective interest net to DeepTech's interest).  The
Partnership's operations consist primarily of the gathering and transportation
of natural gas and crude oil through its pipelines.

     TATHAM OFFSHORE.  Tatham Offshore is an independent energy company engaged
in the development and production of, and the exploration for, offshore oil and
gas reserves, with activities concentrated in the Flextrend and Deepwater areas
of the Gulf.  As of June 30, 1996, DeepTech owns approximately 39% of Tatham
Offshore's outstanding common stock.  In addition, DeepTech owns, through
DeepFlex Services, 4.7 million shares of Series A Preferred Stock and 5.3
million warrants of Tatham Offshore and the Partnership owns 7,500 shares of
Senior Preferred Stock of Tatham Offshore.

RESULTS OF OPERATIONS

Year Ended June 30, 1996 Compared with Year Ended June 30, 1995

     Oil and gas sales totaled $44.5 million for the year ended June 30, 1996
as compared with $18.7 million for the year ended June 30, 1995.  During the
year ended June 30, 1996 and 1995, the Company derived its oil and gas revenue
by marketing primarily Tatham Offshore's, Flextrend Development's, Manta Ray's
and third-party producers' gas and oil production.  During the year ended June
30, 1996, the Company sold 13,679 MMcf of gas and 543,730 barrels of oil at
average prices of $2.47 per Mcf and $19.58 per barrel, respectively. During the
same period in 1995, the Company sold 6,026 MMcf of gas and 458,000 barrels of
oil and condensate at average prices of $1.70 per Mcf and $18.46 per barrel,
respectively.

     Equity in earnings totaled $10.5 million for the year ended June 30, 1996
as compared with $6.0 million for the same period in 1995.  Equity in earnings
for the year ended June 30, 1996 primarily included equity in earnings of the
Partnership and DeepFlex Partners of $9.1 million and $1.3 million,
respectively, whereas, equity in earnings for the same period in 1995 primarily
included equity in earnings of the Partnership of $5.9 million. During the year
ended June 30, 1996, the Partnership had total revenue of $60.9 million as
compared with total Partnership revenue of $36.2 million for the year ended
June 30, 1995.  For the year ended June 30, 1996, the total throughput, net to
the combined interest of the 

                                      37


<PAGE>   40

Partnership in the Pipelines, was 470.4 Bcf as compared with 435.7 Bcf for the
year ended June 30, 1995. During the year ended June 30, 1996, DeepFlex     
Partners, which was formed in March 1995, recorded net income of $2.6 million
which included a gain on the sale of the FPS Eddie Delahoussaye, of $5.1
million.

     Other revenue for the year ended June 30, 1996 totaled $0.5 million as
compared with $0.7 million for the year ended June 30, 1995 and was primarily
attributable to revenue in respect of professional services rendered by Dover
to Tatham Offshore and the Partnership.  Commencing November 1, 1995, DeepTech
accounts for its investment in Dover using the equity method of accounting.

     Operating expenses for the year ended June 30, 1996 totaled $0.5 million
as compared with $0.2 million for the year ended June 30, 1995 and included
costs to operate the Company's multi-purpose service vessel and to terminate
the related charter agreement effective October 1, 1995.  The Company began
chartering the vessel in May 1995 at an initial base rate of $6,980 per day.

     Oil and gas purchases for the year ended June 30, 1996 totaled $43.7
million as compared with $17.4 million for the year ended June 30, 1995.  The
activity for both periods represented the cost of oil and gas purchased from
Tatham Offshore, Manta Ray and third parties for resale.  The activity for the
seven months from December 1995 to June 1996 also included the cost of
production purchased from Flextrend Development.  During the year ended June
30, 1996, the Company purchased 13.7 Bcf of gas and 543,730 barrels of oil at
average prices of $2.44 per Mcf and $18.76 per barrel, respectively. During the
year ended June 30, 1995, the Company purchased 6.0 Bcf of gas and 458,000
barrels of oil at average prices of $1.59 per Mcf and $16.93 per barrel,
respectively.

     Losses of equity investees for the year ended June 30, 1996 totaled $1.9
million as compared with $13.9 million for the year ended June 30, 1995 and
related to equity losses of Tatham Offshore.  During the year ended June 30,
1996, Tatham Offshore had total operating revenue of $16.1 million and
nonoperating income of $22.8 million which was primarily related to the sale of
the Assigned Properties to Flextrend Development.  During the year ended June
30, 1996, Tatham Offshore sold 3,274 MMcf of gas and 418,000 barrels of oil at
average prices of $2.51 per Mcf and $18.83 per barrel, respectively.  For the
year ended June 30, 1996, Tatham Offshore's depreciation and operating expenses
totaled $29.9 million and nonoperating expenses totaled $8.2 million.  During
the year ended June 30, 1995, Tatham Offshore had total revenue of $8.1 million
and sold 1,505 MMcf of gas and 333,000 barrels of oil at average prices of
$1.67 per Mcf and $16.67 per barrel, respectively.  During the year ended June
30, 1995, Tatham Offshore had nonoperating income of $2.3 million, depreciation
and operating expenses of $33.5 million and other nonoperating expenses of
$11.6 million.

     Depreciation and amortization totaled $0.2 million for the year ended June
30, 1996 as compared with $0.3 million for the year ended June 30, 1995.
Depreciation for both periods related to the Company's vehicles and office
furniture and equipment.

     General and administrative expenses for the year ended June 30, 1996
totaled $3.8 million as compared with $3.5 million for the year ended June 30,
1995.  The increase in general and administrative expenses was attributable to
increased operating activities of DeepTech and its consolidated Subsidiaries as
well as expenses incurred associated with DeepTech's deferred compensation
arrangements and a bonus awarded related to the sale of the FPS Eddie
Delahoussaye.  This increase in general and administrative expenses is
partially offset by a $1.0 million charge to the Partnership to compensate the
Company for additional taxable income allocated to Leviathan as a result of the
secondary offering of Partnership Preference Units. Pursuant to management fee
agreements with each of Tatham Offshore and Leviathan, DeepTech is reimbursed
for a portion of its general and administrative expenses. Prior to November 1,
1995, Leviathan and Tatham Offshore were each charged 40% of DeepTech's
overhead expenses under their respective management agreements.  The remaining
20% of DeepTech's overhead costs were allocated to consolidated Subsidiaries.
Effective November 1, 1995, as a result of a reallocation of the level of
services DeepTech provides to its Subsidiaries, DeepTech amended its existing
management agreements with its Subsidiaries and began charging Leviathan and
Tatham Offshore 45.3% and 27.4%, respectively, of overhead costs. The remaining
27.3% of DeepTech's overhead expenses are now allocated to consolidated
Subsidiaries.  For the year ended June 30, 1996, Leviathan and Tatham Offshore
were charged $7.0 million and $4.4 million, respectively, by DeepTech pursuant
to their management agreements.  For the year ended June 30, 1995, Leviathan
and Tatham Offshore were each charged $5.0 million by DeepTech.

     Operating income for the year ended June 30, 1996 totaled $5.4 million as
compared with an operating loss of $10.0 million for the year ended June 30,
1995.  The change in operating income represented the net effect of the items
discussed above.

     Interest and other income for the year ended June 30, 1996 totaled $14.7
million as compared with $8.2 million for the year ended June 30, 1995.
Interest and other income for the year ended June 30, 1996 included interest
income derived from (i) the Tatham Offshore Subordinated Notes of $7.1 million,
(ii) the PIK Notes of $5.9 million, (iii) the Bridge Loan of $0.2 million, (iv)
available cash of $0.4 million, (v) other affiliate debt of $0.2 million and
(vi) other of $0.9 million.  Interest and other income for the year ended June
30, 1995 included interest income derived from the Tatham Offshore Subordinated
Notes of $7.1 million and available cash of $0.4 million and other income of
$0.7 million.

     Interest and other financing costs for the year ended June 30, 1996
totaled $13.1 million as compared with $10.0 million for the year ended June
30, 1995.  Interest and other financing costs for the year ended June 30, 1996
included (i) interest and amortization of debt issue costs and discounts
related to the Senior Notes of $10.7 million, (ii) interest and amortization of
debt issue costs related to DeepTech's subordinated notes of $0.6 million and
(iii) interest related to the Wilrig Notes, Term Loan and other of $1.8
million. During the year ended June 30, 1996, the Company capitalized interest
of $1.0 million related to the Highwood Notes.  Interest and other financing
costs for the year ended June 30, 1995 included interest and amortization of
debt issue costs and discounts related to the Senior Notes of $10.7 million and
$1.7 million of interest expense related to other debt offset by capitalized
interest on construction and refurbishment activities related to the FPS Laffit
Pincay of $2.4 million.

     During the year ended June 30, 1996, the Company recorded income tax
expense of $2.4 million, reflecting an effective tax rate of approximately 34%.
During the year ended June 30, 1995, the Company recorded an income tax
benefit of $3.8 million, reflecting an effective tax rate of approximately 33%.
The effective tax rate for such period reflected the federal statutory rate of
34% as adjusted for certain expenses that are not deductible for tax purposes.

     After taking into account a $0.9 million loss resulting from minority
interests in consolidated subsidiaries, the Company's net income for the year
ended June 30, 1996 totaled $3.6 million.  For the year ended June 30, 1995,
the Company reported a net loss of $8.4 million after taking into account a
$0.5 million loss resulting from minority interests in consolidated
subsidiaries.

Year Ended June 30, 1995 Compared with Year Ended June 30, 1994

     Oil and gas sales totaled $18.7 million for the year ended June 30, 1995
as compared with $23.6 million for the year ended June 30, 1994.  Since August
1993, the Company had primarily derived its oil and gas revenue by marketing
Tatham Offshore's natural gas, condensate and oil production.  In October 1993,
the Company commenced its marketing efforts with third-party producers. Tatham
Offshore sells its production from its West Delta and Ewing Bank leases to
Offshore Marketing at current posted prices for resale to third-party
purchasers.  During the year ended June 30, 1995, the Company sold 6,026 MMcf
of gas and 458,000 barrels of oil and condensate at average prices of $1.70 per
Mcf and $18.46 per barrel, respectively.  During the same period in 1994, the
Company sold 6,823 MMcf of gas and 548,000 barrels of oil and condensate at
average prices of $2.16 per Mcf and $15.60 per barrel, respectively.  The
decrease in oil and gas sales volumes was attributable to lower production by
Tatham Offshore as a result of the Ewing Bank 914 #2 well being impaired or
shut-in during the first two quarters of fiscal 1995 due to the paraffin
build-up in the subsea flow lines.  The decrease in production for Tatham
Offshore of 2,250 MMcf was offset by an increase in the volumes of natural gas
marketed for an affiliate of the Partnership and third-party producers of 1,461
MMcf.

     Equity in earnings totaled $6.0 million for the year ended June 30, 1995
as compared with $7.9 million for the year ended June 30, 1994.  Equity in
earnings for the year ended June 30, 1995 primarily reflected Leviathan's 27.3%
effective interest in the Partnership, whereas, equity in earnings for the same
period in 1994 reflected Leviathan's 35.8% effective interest in the
Partnership (prior to the Partnership's second primary offering of 3,000,000
Preference Units in June 1994).  During the year ended June 30, 1995, the
Partnership had total operating revenue of $36.2 million as compared with total
operating revenue of $30.5 million for the year ended June 30, 1994.  For the
year ended June 30, 1995, the total throughput, net to the 

                                      39


<PAGE>   42

combined interest of the Partnership in the Pipelines, was 435.7 Bcf as compared
with 424.3 Bcf for the year ended June 30, 1994.

     Other revenue for the year ended June 30, 1995 totaled $0.7 million as
compared with $2.0 million for the year ended June 30, 1994 and, in both years,
was primarily attributable to revenue in respect of professional services
rendered by Dover.  Dover provided professional services to Tatham Offshore and
the Partnership during the year ended June 30, 1995 and to Tatham Offshore, the
Partnership and an unaffiliated third party during the same period in 1994.
The decrease in other revenue is primarily attributable to the amendment of a
technology services agreement between Dover and Tatham Offshore which was
effective July 1, 1994.  Under the amended agreement, Dover receives a fixed
fee of $50,000 per month.  In addition, Deepwater Systems recorded revenue in
respect of construction and engineering services provided to the Partnership
during the year ended June 30, 1994.

     Production and operating expenses for the year ended June 30, 1995 totaled
$0.2 million as compared with $4.9 million for the year ended June 30, 1994.
Production and operating costs for the year ended June 30, 1995 included only
costs to operate the Company's multipurpose service vessel, which the Company
began chartering in May 1995 at an initial base rate of $6,980 per day.
Included in production and operating expenses for the year ended June 30, 1994
were costs to operate Tatham Offshore's West Delta 35, Ewing Bank Block 914 #2
and West Cameron 436 wells for the period from July 1, 1993 through February
14, 1994 and costs to transport oil, gas and condensate from the Ewing Bank 914
#2 well through a gathering line owned by the Partnership through February 14,
1994.  For the period February 15, 1994 through June 30, 1994, 40% of $3.9
million, or $1.5 million, was included in losses of equity investees as a
result of DeepTech's change to the equity method of accounting for Tatham
Offshore as of February 15, 1994.  The Company's share of these expenses, 40%
of $13.7 million, or $5.5 million, was included in losses of equity investees
for the year ended June 30, 1995.

     Oil and gas purchases for the year ended June 30, 1995 totaled $17.4
million as compared with $15.0 million for the year ended June 30, 1994.  The
activity for both periods represented the cost of oil and gas purchased from
third parties for resale and certain transportation expenses incurred in
connection with oil purchased from Tatham Offshore for resale.  Since the
Company did not commence its marketing efforts with third-party producers until
October 1993, the year ended June 30, 1994 only included nine months of
third-party producers' marketing activity.  During the year ended June 30,
1995, the Company purchased 6,026 MMcf of gas and 458,000 barrels of oil and
condensate at average prices of $1.59 per Mcf and $16.93 per barrel,
respectively.  During the year ended June 30, 1994, the Company purchased 4,535
MMcf of gas and 341,000 barrels of oil and condensate at average prices of
$2.13 per Mcf and $13.36 per barrel, respectively.  In addition, the Company
incurred $0.8 million in transportation expenses for oil and condensate
purchased for resale during the year ended June 30, 1994.  Oil and gas
purchases subsequent to February 14, 1994 included the purchase cost of oil,
condensate and gas produced by Tatham Offshore.

     Losses of equity investees for the year ended June 30, 1995 totaled $13.9
million and represented DeepTech's 40% equity ownership interest in Tatham
Offshore's operations.  For the period from July 1, 1993 through February 14,
1994, Tatham Offshore's results of operations were consolidated with DeepTech's
results of operations.  Losses of equity investees for the period from February
15, 1994 through June 30, 1994 totaled $2.4 million.  During the year ended
June 30, 1995, Tatham Offshore had total revenue of $8.1 million as compared
with total revenue of $12.1 million for the year ended June 30, 1994.  During
the year ended June 30, 1995, Tatham Offshore sold 1,505 MMcf of gas and
333,000 barrels of oil and condensate at average prices of $1.67 per MMcf and
$16.67 per barrel, respectively. During the same period in 1994, Tatham
Offshore sold 2,937 MMcf of gas and 395,000 barrels of oil and condensate at
average prices of $2.34 per MMcf and $13.36 per barrel, respectively.  During
the year ended June 30, 1995, Tatham Offshore reserved the costs incurred
through June 30, 1995 of $10.6 million associated with the drilling of its
Ewing Bank 915 #4 and Viosca Knoll 818 #1 wells.

     For the year ended June 30, 1994, income associated with a turnkey
construction contract totaled $0.8 million.  An estimate of the difference
between the turnkey price of $16.0 million and the total cost of $18.7 million
was recognized as a loss during the year ended June 30, 1993 and adjusted to
actual in the year ended June 30, 1994.  The cost overrun was a result of
delays in the completion of the installation caused by technical difficulties
encountered by a third party subcontractor with certain equipment manufactured
by such subcontractor.


                                      40


<PAGE>   43

     Exploration expenses for the year ended June 30, 1995 totaled $0.1 million
as compared with $0.4 million for the year ended June 30, 1994.  For the year
ended June 30, 1995, exploration expenses consisted primarily of the purchase of
seismic data by Dover.  For the year ended June 30, 1994, exploration expenses
consisted primarily of Tatham Offshore's delay rentals, minimum royalties and
the purchase of seismic data prior to the Tatham Offshore Offering on February
14, 1994.

     Depreciation, depletion and amortization totaled $0.3 million for the year
ended June 30, 1995 as compared with $0.5 million for the prior year.
Depreciation and depletion costs applicable to Tatham Offshore's investment in
West Delta Block 35 and the Ewing Bank 914 #2 well prior to the Tatham Offshore
Offering accounted for the majority of the costs for the year ended June 30,
1994, whereas, depreciation for the year ended June 30, 1995 related only to
the Company's vehicles and office furniture and equipment.  The Company's share
of Tatham Offshore's depreciation and depletion for the year ended June 30,
1995, 40% of $1.2 million, or $0.5 million, was included in losses of equity
investees. The Company's share of Tatham Offshore's depreciation and depletion
for the period February 15, 1994 through June 30, 1994, 40% of $0.7 million, or
$0.3 million, was included in losses of equity investees.

     General and administrative expenses for the year ended June 30, 1995
totaled $3.5 million as compared with $5.3 million for the year ended June 30,
1994.  The decrease in general and administrative expenses was partially
attributable to the reimbursement to DeepTech of a larger portion of its
general and administrative expenses by Leviathan pursuant to a revision in
DeepTech's management fee agreement with Leviathan as amended effective July 1,
1994.  During the year ended June 30, 1995, Leviathan was charged $5.0 million
by DeepTech pursuant to its management agreement as compared with $2.0 million
for the year ended June 30, 1994.  In addition, for the period from July 1,
1993 through February 14, 1994, Tatham Offshore's general and administrative
expenses were consolidated with those of DeepTech, and included in losses of
equity investees for the period from February 15, 1994 through June 30, 1994,
whereas, for the year ended June 30, 1995, DeepTech's share of Tatham
Offshore's expenses was included in losses of equity investees.  During the
year ended June 30, 1995, Tatham Offshore was charged $5.0 million by DeepTech
pursuant to its management agreement as compared with $3.4 million for the year
ended June 30, 1994.

     Operating loss for the year ended June 30, 1995 totaled $10.0 million as
compared with $5.9 million of operating income for the year ended June 30,
1994.  The operating loss primarily represented the net effect of the items
discussed above.

     During the year ended June 30, 1994, the Company recognized a $31.8
million pretax gain in connection with the Tatham Offshore Offering as a result
of adjusting the carrying value of its investment in Tatham Offshore to 40% of
Tatham Offshore's net equity immediately after the Tatham Offshore Offering.

     Interest and other financing costs, net of interest income and other, for
the year ended June 30, 1995 totaled $1.8 as compared with $6.4 million for the
year ended June 30, 1994.  Interest and other financing costs, net of interest
income, for the year ended June 30, 1995, included interest and amortization of
debt issue costs and discounts related to the Senior Notes of $10.7 million and
interest expense related to other debt of $1.7 million, offset by interest
income derived from the Tatham Offshore Subordinated Notes of $7.1 million,
interest income from cash on hand of $0.6 million, capitalized interest
relating to Deepwater Systems' floating production system construction
activities of $2.4 million and other income of $0.5 million.  Interest expense
and other financing costs, net of interest income for the year ended June 30,
1994 included interest and amortization of debt issue costs and discounts
related to the Senior Notes of $3.0 million, $5.4 million of interest expense
on debt ultimately refinanced with the Senior Notes and $1.0 million of
interest expense related to other debt offset by interest income derived from
the Tatham Offshore Subordinated Notes of $1.5 million, interest income from
cash on hand of $0.5 million and capitalized interest relating to Deepwater
Systems' floating production system construction activities of $1.0 million.

     During the year ended June 30, 1995, the Company recorded an income tax
benefit of $3.8 million, reflecting an effective tax rate of approximately 33%.
The effective tax rate for such period reflected the federal statutory rate of
34% as adjusted for certain expenses that are not deductible for tax purposes.
During the year ended June 30, 1994, the Company recorded an income tax expense
of $3.7 million, which consisted of approximately $0.4 million as a result of
the Company implementing Statement of Financial Accounting Standard No. 109,
"Accounting for Income Taxes," during the period, and approximately $3.3
million which was impacted by a consolidated subsidiary incurring
non-deductible losses.

     After taking into account a $0.5 million loss resulting from the minority
interests in consolidated subsidiaries, the Company's net loss for the year
ended June 30, 1995 totaled $8.4 million.  For the year ended June 30, 1994, the
Company reported a net income of $26.0 million after taking into account accrual
to redemption value and accrued and paid dividends of $0.7 million on capital
stock of subsidiaries, and a $0.9 million loss resulting from minority interests
in consolidated subsidiaries.
                                                              
LIQUIDITY AND CAPITAL RESOURCES

     DEEPTECH

     Sources of Cash.  As a holding company whose material assets consist
primarily of stock of the Subsidiaries, DeepTech is, and expects to continue to
be, dependent upon management fees, dividends funded by distributions from the
Partnership and interest on and repayment of principal under borrowings by the
Subsidiaries (principally the Tatham Offshore Subordinated Notes and the PIK
Notes issued by DeepFlex Partners) to pay its operating expenses, service its
debt and satisfy its other obligations.

     DeepTech has entered into management agreements with each of the
Subsidiaries.  The management fees charged to the Subsidiaries are intended to
approximate the amount of resources allocated by DeepTech to each such
Subsidiary.  Each of the management agreements has an initial term expiring on
June 30, 1997, and may be terminated thereafter upon 90 days' notice by either
party thereto.  Historically, management fees payable by each Subsidiary during
its developmental stage have been funded through advances by DeepTech to each
such Subsidiary, thereby reducing cash available to DeepTech.

     With respect to the management agreements with Leviathan, Tatham Offshore,
DeepFlex Services, Offshore Marketing and Dover, DeepTech charged each such
company, prior to November 1, 1995, an annual management fee of $2.0 million,
$2.0 million, $375,000, $375,000 and $250,000, respectively, plus 40%, 40%,
7.5%, 7.5% and 5%, respectively, of DeepTech's unreimbursed selling, general
and administrative expenses in exchange for operational, financial, accounting
and administrative services. Effective November 1, 1995, Dover began
functioning as a stand alone business unit with its own management and
employees and therefore terminated its management agreement with DeepTech.  As
a result of a reallocation of the level of services provided to each of the
Subsidiaries, DeepTech amended its existing management agreements with each of
its Subsidiaries, effective November 1, 1995, to reflect the revised level of
management fees payable by each Subsidiary.  Effective November 1, 1995,
DeepTech charges Leviathan, Tatham Offshore, DeepFlex Services and Offshore
Marketing 45.3%, 27.4%, 18.8% and 8.5%, respectively, of DeepTech's overhead
expenses.  For the year ended June 30, 1996, Leviathan and Offshore Marketing
made their required cash payments to DeepTech for their management fees.
Leviathan was reimbursed by the Partnership for management fees relating to the
conduct and business of the Partnership.  For the year ended June 30, 1996,
DeepTech charged Tatham Offshore $4.4 million under its management agreement.
These costs were effectively paid when DeepFlex Services exercised 4,670,957
Tatham Offshore warrants to purchase an equal number of shares of Tatham
Offshore Series A Preferred Stock at $1.00 per share by offsetting the then
outstanding DeepTech receivable from Tatham Offshore by $4.7 million.  DeepFlex
Services, which is currently charged 18.8% of DeepTech's general and
administrative overhead costs, did not make payments of management fees to
DeepTech during such period.

     In addition to management fees, DeepTech receives, through dividends from
Leviathan Holdings, an 85%-owned subsidiary of DeepTech, its proportionate
share of distributions paid by the Partnership to Leviathan in respect of
Leviathan's general partner interest, limited partner interest evidenced by
Common Units and interest in certain Operating Companies of the Partnership.
Commencing in the third calendar quarter of 1993, the Partnership increased the
quarterly distribution to $0.60 per Preference Unit and Common Unit from $0.55
per Preference Unit and Common Unit.  Beginning with the quarter ending March
31, 1996, the Partnership increased the quarterly distribution to $0.65 per
Unit.  For the quarter ending June 30, 1996, the Partnership increased the
quarterly distribution to $0.70 per Unit.  As a result, DeepTech's
proportionate share of the aggregate distributions paid to Leviathan for the
year ended June 30, 1996 was approximately $8.8 million.  Leviathan is also
required to reimburse DeepTech for certain tax liabilities DeepTech incurs in
connection with certain matters relating to the operations of the Partnership.

     DeepTech currently holds Tatham Offshore Subordinated Notes with an
aggregate principal amount of $60.0 million, representing all of the Tatham
Offshore Subordinated Notes outstanding.  The Tatham 

                                      42


<PAGE>   45

Offshore Subordinated Notes bear interest at a rate of 11 3/4% per annum,
payable quarterly in arrears (an aggregate of approximately $7.1 million per
year); provided, however, effective July 1, 1997, interest shall accrue at a
rate of 13% per annum. For the year ended June 30, 1996, interest income under
the Subordinated Notes totaled $7.1 million.  The principal amount of the Tatham
Offshore Subordinated Notes is payable in seven equal annual installments
commencing August 1, 1999.

     In September 1995, the Company sold the FPS Eddie Delahoussaye (on behalf
of DeepFlex Partners) to Reading & Bates (U.K.) Limited for $18.0 million which
was comprised of (i) $3.0 million, (ii) 1,232,057 shares of Reading & Bates
common stock and (iii) the forgiveness of $0.3 million of trade receivables due
Reading & Bates from a wholly-owned subsidiary of DeepTech.  DeepFlex Partners
transferred approximately $17.8 million net sales proceeds (including the
Reading & Bates common stock) to DeepFlex Services as repayment of a portion of
the PIK Notes issued by DeepFlex Partners.  The Reading & Bates common stock
was sold for $14.7 million in October 1995.

     In December 1995, the Company issued the Highwood Notes to Highwood
Partners for an aggregate principal amount of $13.5 million for the purchase of
the FPS Bill Shoemaker.  In connection with the caretakership and refurbishment
of the FPS Bill Shoemaker and FPS V's purchase of Highwood Partners' 50%
interest on June 30, 1996, the Company issued an additional $3.8 million of
Highwood Notes.  The Highwood Notes are secured by a mortgage on the FPS Bill
Shoemaker and approximately $3.0 million of PIK Notes, bear interest at 12%,
payable quarterly and are due March 31, 1997. In July 1996, the Company
borrowed an additional $1.0 million for refurbishment costs bringing the total
amount of outstanding Highwood Notes to $18.3 million.  In connection with the
issuance of the Highwood Notes, DeepTech granted Highwood Partners warrants,
which expire on December 5, 1997, to acquire 472,973 shares of DeepTech common
stock at $5.00 per share.  The Company intends to use the proceeds from the
Lehman Commitment to repay the Highwood Notes as discussed below.

     In February 1996, DeepFlex Services entered into the Term Loan to borrow
$12.0 million from a syndicate of commercial lenders.  The Term Loan bears
interest at 12% per annum, payable monthly, is due on July 15, 1997 and is
secured by substantially all tangible and intangible assets currently owned by
DeepFlex Services, including 5,329,043 Tatham Offshore warrants, 4,670,957
shares of Series A Preferred Stock and all PIK Notes issued by DeepFlex
Partners, except the $3.0 million of PIK Notes pledged under the Highwood
Notes.  In addition, the lenders required an assignment by DeepFlex Services of
the first preferred ship mortgage on the FPS Laffit Pincay which is securing
the PIK Notes.  In connection with the Term Loan, DeepTech issued to the
lenders warrants to purchase an aggregate of up to 2,666,667 shares of DeepTech
common stock at $4.50 per share.  One of the lenders, Citibank, N.A., required
that Mr. Tatham guarantee $6.0 million of the Term Loan.  In exchange for Mr.
Tatham agreeing to guarantee a portion of the Term Loan, Mr. Tatham received
from Citibank, N.A. warrants to purchase 333,333 shares of DeepTech common
stock, twenty-five percent of the loan fees payable by the Company to Citibank,
N.A. and a quarterly fee equal to 50 basis points per annum for the period the
guaranty is outstanding.  Proceeds from the Term Loan were utilized to repay
$3.5 million of DeepTech short-term notes, for expenses incurred in connection
with the Term Loan and for working capital and general corporate requirements.
DeepFlex Services is required to make monthly principal payments equal to its
excess cash flow as defined in the Term Loan agreement beginning in October
1996.  Interest expense and amortization of debt issue costs related to the
Term Loan for the year ended June 30, 1996 totaled $0.8 million.  The Company
intends to use the proceeds from the Lehman Commitment to repay the Term Loan
as discussed below.

     In July 1996, DeepTech obtained the Lehman Commitment in an aggregate
amount of up to $55.0 million.  The two-year credit facility is expected to be
made available to RIGCO.  RIGCO anticipates using the proceeds from the credit
facility to acquire the FPS Bill Shoemaker and to perform significant upgrades
to the rig.  RIGCO intends to acquire the FPS Laffit Pincay from DeepFlex
Partners for the assumption of the PIK Notes.  The credit facility will be
secured by the FPS Laffit Pincay and the FPS Bill Shoemaker.  In connection
with the acquisition of the FPS Bill Shoemaker, the rig related debt payable
under the Term Loan and Highwood Notes will be paid in full. The credit
facility will require a quarterly principal payment of excess cash flow as
defined in the credit agreement with a minimum principal amortization of
$250,000 per quarter.  The credit facility remains subject to the negotiation
and execution of definitive documents.

     In February 1996, DeepFlex Partners' FPS Laffit Pincay began providing
contract drilling services to Flextrend Development, which will continue until
Flextrend Development completes the drilling of its Garden Banks Block 117 #2
well.  During the year ended June 30, 1996, DeepFlex Partners provided 


                                      43


<PAGE>   46
services totaling $1.1 million under this agreement.  Net proceeds from the
contract drilling services have been used to pay interest and principal to
DeepFlex Services on the PIK Notes.                                             

     Uses of Cash.  Management expects that the Company's nondiscretionary
expenditures through June 30, 1997 will consist primarily of (i) scheduled
payments of interest on the Senior Notes of $4.9 million on June 15 and
December 15 of each year, or $9.8 million on an annual basis, (ii) scheduled
interest payments on the Term Loan of $120,000 per month or $1.4 million on an
annual basis and scheduled principal payments equal to DeepFlex Services'
excess cash flow as defined in the Term Loan agreement beginning October 1996,
(iii) scheduled interest payments on the Wilrig Promissory Notes of $275,000
per quarter, or $1.1 million on an annual basis, (iv) scheduled interest
payments on the Highwood Notes of $548,000 per quarter and principal of $18.3
million due in March 1997, (v) scheduled payments of interest on affiliate
indebtedness of $249,000 per quarter and principal of $6.6 million due in
January 1997 and (vi) amounts necessary to pay general and administrative and
other operational expenses.

     The Company anticipates that its discretionary expenditures for the year
ending June 30, 1997 will include additional investments in its contract
drilling services business, consisting of capital expenditures necessary to
perform an extensive upgrade, repair and refurbishment program on the FPS Bill
Shoemaker to enable it to perform contract drilling services, and amounts
necessary to exercise DeepFlex Services' 5,329,043 Tatham Offshore warrants to
acquire shares of Convertible Exchangeable Preferred Stock.  See "-- Tatham
Offshore."

     As discussed above, the Company anticipates that its contract drilling
services business will be operated through RIGCO and that the credit facility
which is contemplated under the Lehman Commitment will provide the funding to
repay the Term Loan and Highwood Notes as well as fund the capital expenditures
necessary to upgrade the FPS Bill Shoemaker.

     In January 1996, DeepFlex Services subscribed for the purchase of
10,000,000 Tatham Offshore warrants at a total cost of $5.0 million which was
paid through the forgiveness of $5.0 million of principal and interest due
under a bridge loan to Tatham Offshore.  The Company exercised 4,670,957 of the
warrants to acquire Series A Preferred Stock from Tatham Offshore by forgiving
$4.7 million in management fees that would otherwise be due from Tatham
Offshore.  The Company has not yet determined when, or if, it will exercise its
remaining Tatham Offshore warrants.  Any Tatham Offshore warrants remaining
unexercised on January 1, 1997 will be automatically converted into shares of
Mandatory Redeemable Preferred Stock of Tatham Offshore.  See "-- Tatham
Offshore."

     Liquidity Outlook.  DeepTech intends to satisfy its capital requirements
and other working capital needs primarily from cash on hand and cash provided
from management fees, dividends funded by distributions from the Partnership,
interest on the Tatham Offshore Subordinated Notes and funds provided from the
Lehman Commitment.  As of June 30, 1996, the Company had $10.1 million of cash
and cash equivalents. DeepTech is and expects to continue to be dependent upon
payments from the Subsidiaries to service its debt, pay its operating expenses
and satisfy its other obligations.  DeepTech's ability to fund the make ready
expenditures on the FPS Bill Shoemaker for the fiscal year ending June 30, 1997
as well as the $18.3 million in principal due on the Highwood Notes in March
1997 and the $12.0 million in principal due on the Term Loan in July 1997 will
be dependent on its ability to fund the Lehman Commitment or to obtain a
similar financing arrangement.  In addition, DeepTech will seek to refinance
all or a portion of the $6.6 million of affiliate indebtedness which is due in
January 1997.

     Based on current projections which assume (i) that approximately $6.6
million of affiliate indebtedness that is due in January 1997 is refinanced,
(ii) the Company receives interest payments on the Tatham Offshore Subordinated
Notes when due and (iii) that DeepFlex Services is able to obtain funding under
the Lehman Commitment or a similar financing agreement on a timely basis,
DeepTech believes that it will have sufficient funds to meet its anticipated
capital needs including scheduled payments on indebtedness and make ready
expenditures on the FPS Bill Shoemaker.

     DeepTech anticipates that it will need significant additional funds from
outside sources to fund its financial obligations which mature in late 1997 and
beyond.  These obligations include the repayment by DeepFlex Services of its
$11.0 million note to Wilrig which is due in November 1997, the repayment by
RIGCO of the remaining balance of the funds obtained pursuant to the Lehman
Commitment and the principal balance of $82.0 million under DeepTech's Senior
Notes which are due in June 2000.  The 

                                      44


<PAGE>   47

Company contemplates raising such funds through (i) the issuance of additional
debt or debt refinancing at the DeepTech or subsidiary level, (ii) the sale of
equity securities at the subsidiary level, (iii) a repayment of amounts due
DeepTech from Tatham Offshore and/or DeepFlex Services and/or (iv) the exercise
of outstanding warrants to acquire DeepTech common stock.  However, there can be
no assurance that the Company will be able to raise capital on terms it deems
acceptable on a timely basis.  Further, the Senior Note Indenture contains
covenants that, among other things, require DeepTech to meet certain collateral
coverage tests and restrict the ability of DeepTech to incur additional
indebtedness, effect certain asset sales and engage in certain mergers or
similar transactions.  The failure to obtain additional capital would have a
material adverse effect on DeepTech's financial condition and results of
operations.

     LEVIATHAN/THE PARTNERSHIP

     Sources of Cash.  The Partnership intends to satisfy its capital
requirements and other working capital needs primarily from cash on hand, cash
from continuing operations and borrowings under the Partnership Credit
Facility.  Net cash provided by operating activities for the six months ended
June 30, 1996 totaled $5.1 million.  At June 30, 1996, the Partnership had cash
and cash equivalents of $5.5 million.

     Cash from continuing operations is derived from (i) payments for
transporting gas through the 100% owned pipelines, (ii) cash distributions from
the Stingray, HIOS, UTOS and Viosca Knoll partnerships and from POPCO and West
Cameron Dehy, (iii) platform access and processing fees and (iv) the sale of
oil and gas attributable to the Partnership's interest in certain producing
wells.

     Stingray, HIOS, UTOS and Viosca Knoll are partnerships and POPCO and West
Cameron Dehy are limited liability companies in which the Partnership owns an
interest.  The Partnership's cash flows from operations will be affected by the
ability of such entities to make distributions.  Distributions from such
entities are also subject to the discretion of their respective management
committees.  Further, each of Stingray and POPCO is party to a credit agreement
under which it has outstanding obligations that may restrict the payments of
distributions to its owners.  In December 1995, Stingray amended an existing
term loan agreement to provide for aggregate outstanding borrowings of up to
$29.0 million in principal amount. The agreement requires the payment of
principal by Stingray of $1.45 million per quarter.  As of June 30, 1996,
interest accrued at the rate of approximately 6.4% per annum and is payable
quarterly.  As of June 30, 1996, Stingray had $27.55 million outstanding under
its term loan agreement.

     In April 1996, POPCO entered into a revolving credit facility (the "POPCO
Credit Facility") with a group of commercial banks to provide up to $150.0
million for the construction of the second phase of the Poseidon Oil Pipeline
and for other working capital needs of POPCO.  As of June 30, 1996, POPCO had
$40.0 million outstanding under the POPCO Credit Facility bearing interest at
6.7% per annum.  POPCO's ability to borrow money under the facility is subject
to certain customary terms and conditions, including borrowing base
limitations.  The POPCO Credit Facility is secured by a substantial portion of
POPCO's assets and matures on April 30, 2001.

     Flextrend Development has initiated production from the each of the
Assigned Properties.  The Viosca Knoll Block 817 lease is currently producing a
total of approximately 90 MMcf of gas per day.  Flextrend Development owns a
75% working interest in this property, subject to certain reversionary rights.
The Garden Banks Block 72 lease, which began producing in May 1996, is
currently producing an average of approximately 3,600 barrels of oil and 6.5
MMcf of gas per day. The Garden Banks Block 117 #1 well, which began producing
in July 1996, is currently producing an average of approximately 2,02,500
barrels of oil, 5.0 MMcf of gas and 2,900 barrels of water per day. Flextrend
Development owns a 50% working interest in each of these properties, subject to
certain reversionary rights.

     Tatham Offshore was obligated to make demand charge payments to the
Partnership pursuant to certain transportation agreements.  Production problems
at Ship Shoal Block 331 and reduced oil production from the Ewing Bank 914 #2
well have adversely affected Tatham Offshore's ability to pay demand charges
under these agreements.  Effective February 1, 1996, the Partnership agreed to
release Tatham Offshore from all remaining demand charge payments under certain
transportation agreements, a total of $17.8 million. Under these agreements,
the Partnership was entitled to receive demand charges of $8.1 million in 1996,
$6.0 million in 1997, $3.0 million in 1998 and $0.7 million in 1999.  In
exchange, the Partnership received 7,500 shares of Tatham Offshore Senior
Preferred Stock.  Each share of the Senior Preferred Stock has a liquidation
preference of $1,000 per share, is senior in liquidation preference to all
other classes 

                                      45


<PAGE>   48

of Tatham Offshore stock and has a 9% cumulative dividend, payable quarterly. 
Commencing on October 1, 1998 and for a period of 90 days thereafter, the
Partnership has the option to exchange the remaining liquidation preference
amount and accrued but unpaid dividends for shares of Tatham Offshore's
Convertible Exchangeable Preferred Stock with an equivalent market value. 
Further, the Partnership has made an irrevocable offer to Tatham Offshore to
sell all or any portion of the Senior Preferred Stock to Tatham Offshore or its
designee at a price equal to $1,000 per share, plus interest thereon at 9% per
annum less the sum of any dividends paid thereon.  The Convertible Exchangeable
Preferred Stock is convertible into Tatham Offshore common stock based on a
fraction, the numerator of which is the liquidation preference value plus all
accrued but unpaid dividends and the denominator of which is $0.653 per share.
In addition, the sum of $7.5 million was added to the Payout Amount under the
Purchase and Sale Agreement. By adding $7.5 million to the Payout Amount, the
Partnership is entitled to an additional $7.5 million plus interest at the rate
of 15% per annum from revenue attributable to the Assigned Properties prior to
reconveying any interest in the Assigned Properties to Tatham Offshore.  Tatham
Offshore also agreed to grant the Partnership the right to utilize the Ship
Shoal Platform and related facilities at a rental rate of $1.00 per annum for
such period as the platform is owned by Tatham Offshore and located on Ship
Shoal Block 331, provided such use does not interfere with lease operations or
other activities of Tatham Offshore.  In addition, Tatham Offshore granted the
Partnership a right of first refusal relative to a sale of the platform. Tatham
Offshore remains obligated to pay the commodity charges under these agreements
as well as all platform access and processing fees associated with the VK 817
Platform.  For the year ending December 31, 1996, Tatham Offshore is obligated
to pay $1.6 million in platform access fees.

     The Partnership Credit Facility, as amended and restated on March 26,
1996, is a revolving and term credit facility providing for up to $220.0
million of available credit in the form of a $145.0 million revolving credit
facility and $75.0 million term loan facility.  Proceeds from the revolving
credit facility are available to the Partnership for general partnership
purposes, including financing of capital expenditures, for working capital, and
subject to certain limitations, for paying the Minimum Quarterly Distribution,
as defined in the Partnership Agreement.  The revolving credit facility can
also be utilized to issue letters of credit as may be required from time to
time.  As of June 30, 1996, borrowings totaled $75.0 million under the term
facility and $118.0 million under the revolving credit facility.  As of August
30, 1996, borrowings totaled $75.0 million under the term facility and $131.0
million under the revolving credit facility.  There are no letters of credit
currently outstanding under the revolving credit facility.

     Uses of Cash.  The Partnership's capital requirements consist primarily of
(i) quarterly distributions to holders of Preference Units and Common Units and
to Leviathan as general partner, (ii) expenditures for the maintenance of the
pipelines and related infrastructure and the construction of additional
pipelines and related facilities for the transportation and processing of gas
and oil in the Gulf, including the second phase of the Poseidon Oil Pipeline,
(iii) management fees and other operating expenses and (iv) debt service on its
outstanding debt.  In addition, Flextrend Development's future capital
requirements will consist of expenditures related to the continued development
of the Viosca Knoll Block 817, Garden Banks Block 72 and Garden Banks Block 117
leases.

     For every full quarter since its inception, the Partnership has declared
and subsequently paid a cash distribution to holders of Preference Units and
Common Units in an amount equal to or exceeding the Minimum Quarterly
Distribution of $0.55 per Unit per quarter ($2.20 per Unit on an annualized
basis). Commencing in the third quarter of 1993, the Partnership increased the
quarterly distribution to $0.60 per Unit. Beginning with the quarter ending
March 31, 1996, the Partnership increased the quarterly distribution to $0.65
per Unit.  For the quarter ending June 30, 1996, the Partnership increased the
quarterly distribution to $0.70 per Unit.  This distribution was paid on August
14, 1996 to Unitholders of record as of July 31, 1996.  At the current
distribution rate of $0.70 per Unit, the Partnership anticipates making
quarterly Partnership distributions of $8.8 million in respect of the
Preference Units, Common Units and general partner interest ($35.2 million on
an annual basis).  The Partnership believes that it will be able to continue to
pay at least the current quarterly distribution of $0.70 per Preference Unit
for the foreseeable future.

     In February 1996, Poseidon LLC and Texaco Trading formed POPCO to
construct, own and operate the Poseidon Oil Pipeline.  Pursuant to the terms of
the organizational documents, Poseidon LLC initially contributed assets, at net
book value, related to the construction of the initial phase of the Poseidon
Oil Pipeline as well as certain dedication agreements and Texaco Trading
initially contributed an equivalent 

                                      46


<PAGE>   49

amount of cash as well as its rights under certain agreements.  The Partnership
has fully funded its portion of the capital requirements of POPCO for the
construction of the first phase of the Poseidon Oil Pipeline. In July 1996,
Marathon joined POPCO by contributing its interest in 58 miles of nearby crude
oil pipelines and dedicating its portion of oil reserves attached to such
pipelines to the Poseidon Oil Pipeline for transportation.  As a result, each of
the Partnership and Texaco Trading now owns a 36% interest in POPCO and
Marathonowns the remaining 28% interest.  The Partnership anticipates that
POPCO's future capital requirements, including amounts necessary to complete the
second phase of the system, will be funded by borrowings under the POPCO Credit
Facility.

     On July 8, 1996, the Partnership and affiliates of Marathon and Shell
announced plans to build and operate an interstate natural gas pipeline system
and a connecting gathering system to serve growing production areas in the
Green Canyon area of the Gulf.  The total cost of the two systems, including
the Combined Manta Ray System, currently owned by the Partnership, is
approximately $270.0 million.  The new jurisdictional interstate pipeline, to
be named "Nautilus", will consist of a 30-inch line downstream from Ship Shoal
Block 207 connecting to the Marathon operated Burns Point Gas Plant and other
area gas plants. Upstream of the Ship Shoal 207 terminal, the Combined Manta
Ray System will be extended into a broader gathering system that would serve
shelf and deepwater production around Ewing Bank Block 873 to the east and
Green Canyon Block 65 to the west.  Marathon and Shell have significant deep
water acreage positions in the area, including the recently announced Troika
field (Green Canyon Block 244), and would provide the majority of the capital
funding for the new construction.  The Partnership would provide some funding
along with the contribution of the Combined Manta Ray System.  The consummation
of this joint venture is subject to the negotiation and execution of definitive
documents.

     The Partnership anticipates that capital expenditures in connection with
the maintenance and enhancement of the service capabilities of the Ewing Bank,
Green Canyon and Tarpon systems will aggregate approximately $0.5 million per
year although the actual level of these capital expenditures may change from
time to time for many reasons, some of which may be beyond the control of the
Partnership. Total capital expenditures and equity investments for 1995 were
$173.6 million.  The Partnership anticipates that its total capital
expenditures for 1996 will relate to continuing construction and drilling
activities.  The Partnership anticipates funding such costs primarily with
available cash flow and borrowings under the Partnership Credit Facility.
Capital expenditures of POPCO are anticipated to be funded by borrowings under
the POPCO Credit Facility.

     Interest and other financing costs, net of capitalized interest, related
to the Partnership Credit Facility totaled $0.6 million for the six months
ended June 30, 1996.  Such amount included commitment fees and amortization of
debt issue costs of $0.2 million. During the six months ended June 30, 1996,
the Partnership capitalized $6.0 million of interest costs in connection with
construction projects and drilling activities in progress during the period.

     TATHAM OFFSHORE

     Sources of Cash.  Tatham Offshore intends to satisfy its immediate capital
requirements and other working capital needs primarily from cash on hand, cash
generated from continuing operations and proceeds from the exercise of existing
Warrants.  At June 30, 1996, Tatham Offshore had $4.8 million of cash and cash
equivalents.  In addition, Tatham Offshore had an additional $6.4 million of
net working capital including $12.2 million in stock subscriptions receivable
which was collected in July 1996.

     Cash from continuing operations is derived primarily from production from
Tatham Offshore's Phar Lap project which is currently producing approximately
90 MMcf per day.  As of August 30, 1996, there are five wells at Phar Lap which
are capable of production and Flextrend Development is in the process of
completing the first of three additional wells on that project.  The well
deliverability from the Phar Lap project is in excess of the 90 MMcf per day
but is limited to such amount by the processing capability of the production
equipment currently located on the production platform. Flextrend Development
is currently taking steps to add additional equipment to the VK 817 Platform
which is expected to increase the processing capacity to approximately 125 MMcf
per day by mid November 1996. Tatham Offshore currently owns a 25% working
interest in the Phar Lap project which interest is subject to a production
payment equal to 25% of the net operating cash flow from such working interest.

<PAGE>   50


     Tatham Offshore also has producing wells at Ewing Bank 914 # 2 and at its
Silent Beauty project at West Delta Block 35 which contribute to cash from
continuing operations.  Tatham Offshore owns a 100% working interest in the
Ewing Bank 914 #2 well and a 38% working interest in the Silent Beauty project.
During February 1996,  the Ewing Bank 914 #2 well began producing some water
(increasing to approximately 62% of total production by August 30, 1996)
resulting in a reduction of the hydrocarbon production.  The Ewing Bank 914 #2
well is currently producing at a rate of approximately 900 barrels of oil, 2.0
MMcf of gas and 1,600 barrels of water per day.

     As a result of an offering, in February 1996, Tatham Offshore received
$12.6 million in gross proceeds ($11.3 million, net) pursuant to the exercise
of Rights to purchase 25,120,948 Tatham Offshore warrants at $.50 per warrant.
As of July 1, 1996, 18,717,030 of these Tatham Offshore warrants had been
exercised to purchase an equivalent number of shares of Series A Preferred
Stock at $1.00 per share which generated an additional $18.7 million in
proceeds to Tatham Offshore.  Proceeds from the offering through July 1, 1996
were utilized to (i) repay $8.1 million in principal and interest due on a
bridge loan from DeepFlex Services, (ii) pay $4.7 million in management fees
payable by Tatham Offshore to DeepTech pursuant to its management agreement and
(iii) to fund Tatham Offshore's working capital and capital requirements.

     As of July 1, 1996, there were 6,403,918 Tatham Offshore warrants
outstanding.  Each of the remaining Tatham Offshore warrants may be exercised
to purchase one share of (i) Series B 8% Convertible Exchangeable Preferred
Stock, which has a liquidation preference of $1.00 per share ("Series B
Preferred Stock") at any time prior to 5:00 p.m. New York time on October 1,
1996 or (ii) Series C 4% Convertible Exchangeable Preferred Stock, which has a
liquidation preference of $.50 per share ("Series C Preferred Stock" and
together with the Series A Preferred Stock and Series B Preferred Stock, the
"Convertible Exchangeable Preferred Stock") at any time prior to 5:00 p.m. New
York time on January 1, 1997 at the purchase price of $1.00 per share.  Each
Tatham Offshore warrant remaining unexercised at 5:00 p.m. New York time on
January 1, 1997 shall be automatically converted, without any action on the
part of the holder thereof, into one share of Mandatory Redeemable Preferred
Stock , which shall have a liquidation preference of $0.50 per share and shall
be mandatorily redeemable by Tatham Offshore under certain circumstances.  At
any time from July 1, 1996 until December 31, 1998, each share of Convertible
Exchangeable Preferred Stock may be exchanged for four warrants (the "Exchange
Warrants" and together with the Rights, the Tatham Offshore warrants, the
Convertible Exchangeable Preferred Stock and the Mandatory Redeemable Preferred
Stock, the "Securities") each of which entitles the holder thereof to purchase
one share of Tatham Offshore common stock at $0.653 per share.  The Exchange
Warrants will expire July 1, 1999.  Alternatively, at any time after July 1,
1996, the holder of any shares of Convertible Exchangeable Preferred Stock will
have the right, at the holder's option, to convert the liquidation value of
such stock and accrued and unpaid dividends into shares of Tatham Offshore
common stock at the $0.653 per share.   On and after July 1, 1997, the
Convertible Exchangeable Preferred Stock will be redeemable at the option of
Tatham Offshore.  Through August 30, 1996, a total of 320,864 shares of Series
A Preferred Stock had been converted into 737,986 shares of Tatham Offshore's
common stock.

     Uses of Cash. Tatham Offshore's primary uses of cash consist of (i)
amounts due under the Tatham Offshore Subordinated Notes, (ii) expenses
associated with operating its producing properties, including its obligations
under the Drilling Arrangement and its production payment and leasehold
abandonment liabilities, (iii) capital expenditures necessary to fund its
portion of the development costs attributable to its working interest, (iv)
platform access fees and processing and commodity charges payable to the
Partnership, (v) interest and principal on the Tatham Offshore Affiliate Note
and (vi) payments due under the management agreement with DeepTech.

     As of June 30, 1996, Tatham Offshore had $60.0 million aggregate principal
amount of Tatham Offshore Subordinated Notes outstanding, the maximum principal
amount of Tatham Offshore Subordinated Notes issueable, all of which were held
by DeepTech.  The Tatham Offshore Subordinated Notes are subordinate to all
senior indebtedness of Tatham Offshore, which would include the Tatham Offshore
Affiliate Note.  As of the date of this Annual Report, Tatham Offshore did not
have any outstanding indebtedness ranking senior to the Tatham Offshore
Subordinated Notes, except for outstanding indebtedness under the Tatham
Offshore Affiliate Note.  The Tatham Offshore Subordinated Notes bear interest
at a rate of 11 3/4% per annum, payable in arrears (approximately $1.8 million
per quarter); provided, however, that effective July 1, 1997, interest shall
accrue at a rate of 13% per annum.  The principal amount of the Tatham Offshore
Subordinated Notes is payable in seven equal annual installments 

                                      48


<PAGE>   51

of approximately $8.6 million each commencing August 1, 1999.  For the year
ended June 30, 1996, Tatham Offshore paid DeepTech $7.1 million in interest on
the Tatham Offshore Subordinated Notes.

     During the year ended June 30, 1996, Tatham Offshore began incurring
abandonment costs related to its West Cameron 436 property, in which it owns a
47% working interest.  The West Cameron 436 property ceased producing in 1994.
The total estimated abandonment obligation, net to Tatham Offshore's
working interest, of $1.2 million was fully accrued as of June 30, 1995. Through
August 30, 1996, Tatham Offshore has paid approximately $0.8 million of the
estimated abandonment costs.
     
     Tatham Offshore was obligated to make demand charge payments to the
Partnership under certain transportation agreements. Demand charges were
payable whether or not any production was actually transported.  In addition,
Tatham Offshore is obligated to pay commodity charges, based on the volume of
oil and gas transported or processed, under these agreements.  Also, Tatham
Offshore is obligated to pay $1.6 million in platform access fees annually
relative to its 25% working interest in its Phar Lap property. Production
problems at Ship Shoal Block 331 and reduced oil production from the Ewing Bank
914 #2 well affected Tatham Offshore's ability to pay the demand charge
obligations under agreements relative to these properties.  Effective February
1, 1996, Tatham Offshore entered into an agreement with the Partnership to
prepay its remaining demand charge payments under the transportation agreements
covering its Ewing Bank and Ship Shoal properties.  Under the agreement, Tatham
Offshore's demand charge obligations relative to the Ewing Bank Gathering
System and the Ship Shoal Extension have been prepaid in full.  In exchange,
effective February 1, 1996, Tatham Offshore has (i) issued the Partnership
7,500 shares of Senior Preferred Stock with a liquidation preference of $1,000
per share, (ii) added the sum of $7.5 million to the Payout Amount under the
Purchase and Sale Agreement with Flextrend Development and (iii) granted to the
Partnership certain rights to use and acquire the Ship Shoal Platform.  The
Partnership has made an irrevocable offer to Tatham Offshore to sell all or any
portion of the Senior Preferred Stock to Tatham Offshore or its designee at a
price equal to $1,000 per share, plus interest thereon at per annum less the
sum of any dividends paid thereon.  If the Senior Preferred Stock is not
purchased by Tatham Offshore on or before September 30, 1998, it will be
convertible into shares of Tatham Offshore's Series A Preferred Stock based on
the liquidation preference amount of the Senior Preferred Stock and the
equivalent market value of the Series A Preferred Stock as of the date of
conversion.  The increase in the Payout Amount will defer the reversion of
Tatham Offshore's working interest in its Viosca Knoll Block 817, Garden Banks
Block 72 and Garden Banks Block 117 properties under the Purchase and Sale
Agreement and will be excluded for purposes of computing the amount of the
Payout Amount to be extinguished if Flextrend Development exercises one of its
Working Interest Options.  In addition, Tatham Offshore agreed to grant the
Partnership the right to utilize the Ship Shoal Platform and related facilities
at a rental rate of $1.00 per annum for such period as the platform is owned by
Tatham Offshore and located on the Ship Shoal Block 331, provided such use does
not interfere with lease operations or other activities of Tatham Offshore.
Tatham Offshore has granted the Partnership a right of first refusal relative
to a sale of the platform. The agreement with the Partnership reduced demand
charge payments by approximately $4.1 million for the fiscal year ended June
30, 1996, and will result in a reduction of $7.8 million for the fiscal year
ended June 30, 1997 and $5.9 million for fiscal years thereafter.  Tatham
Offshore remains obligated to pay the commodity charges under these agreements
as well as all platform access and processing fees associated with the VK 817
Platform.

     On November 1, 1995, Tatham Offshore converted $1.7 million of its
accounts payable to an affiliate into an unsecured promissory note to DeepTech
(the "Tatham Offshore Affiliate Note") which bears interest at 14.5% per annum.
Interest on the Tatham Offshore Affiliate Note is payable quarterly, beginning
March 31, 1996.  The principal is due and payable in six monthly installments,
beginning on a date which is the earlier of (i) November 1, 1997 or (ii) the
last day of the calendar month in which Tatham Offshore receives proceeds from
the issuance of any preferred stock in an amount equal to or greater than $20.0
million. Interest expense related to the Tatham Offshore Affiliate Note totaled
$0.2 million for the year ended June 30, 1996.

     Effective as of July 1, 1993, the management agreement between Tatham
Offshore and DeepTech provided for an annual management fee equal to 40% of
DeepTech's overhead.  The management fee is intended to reimburse DeepTech for
the estimated costs of its operational, financial, accounting and


                                      49


<PAGE>   52
administrative services provided to Tatham Offshore.  In an effort to minimize
Tatham Offshore's projected operating cash shortfall, Tatham Offshore and
DeepTech agreed to decrease the amount of managerial and administrative services
provided by DeepTech to Tatham Offshore and amend the management agreement
effective November 1, 1995.  The amended management agreement provides for an
annual management fee of 27.4% of DeepTech's overhead expenses. For the year
ended June 30, 1996, Tatham Offshore was charged $4.4 million in management fees
pursuant to the management agreement.    

     Liquidity Outlook.  During the year ended June 30, 1995 and the first six
months of fiscal 1996, Tatham Offshore experienced liquidity problems resulting
primarily from substantial negative cash flow from operations.  In order to
improve liquidity and partially address its capital requirements, Tatham
Offshore (i) sold, subject to certain revisionary rights, all of its working
interests in the Assigned Properties for $30 million to Flextrend Development,
(ii) raised additional equity through the sale of Tatham Offshore warrants and
Series A Preferred Stock, (iii) prepaid certain of its demand charge obligations
through the assignment of certain assets pursuant to an agreement with the
Partnership and (iv) reduced its overhead by lowering the levels of services
required under its management agreement with DeepTech.

     Tatham Offshore is entitled to receive a reassignment of the Assigned
Properties, subject to reduction and conditions as discussed below, after
Flextrend Development has received net revenues equal to the Payout Amount. As
of June 30, 1996, the Payout Amount was $77.7 million comprised of (i) initial
acquisition and transaction costs of $32.1 million, (ii) development and
operating costs of $49.3 million, (iii) prepaid demand charges of $7.5 million
and (iv) interest of $7.1 million reduced by net revenue of $18.3 million.
Tatham Offshore and the Partnership have agreed that in the event Tatham
Offshore furnishes the Partnership with a financing commitment from a lender
with a credit rating of BBB- or better covering 100% of the then outstanding
Payout Amount, the interest rate utilized to compute the Payout Amount shall be
adjusted from and after the date of such commitment to the interest rate
specified in such commitment, whether utilized or not.  At any time prior to
December 10, 1996, Flextrend Development may exercise either of the Working
Interest Options in exchange for forgiving 25% or 50%, respectively, of the
then-existing Payout Amount, exclusive of the $7.5 million plus interest added
to the Payout Amount in connection  with the prepayment of demand charges.  In
the event Flextrend Development elects to reduce the Payout Amount, it will
become obligated to fund any further development costs attributable to Tatham
Offshore's portion of the working interests, such costs to be added to the
Payout Amount.  Otherwise, any further development costs will be funded by
Flextrend Development on a discretionary basis, such costs to be added to the
Payout Amount. Further, in the event Flextrend Development forgoes its right to
permanently retain a working interest in all or a portion of the Assigned
Properties, it will be entitled to recover from working interest revenues in
respect of the Assigned Properties all future demand charges payable for
platform access and processing, in their inverse order of maturity, prior to
any reassignment to Tatham Offshore.  If however, Tatham Offshore (i) satisfies
in full the future demand charges payable for platform access and processing,
(ii) delivers evidence that it has received a rating of BBB-, or better, from
at least two reputable rating agencies or (iii) delivers evidence that an
entity with a rating of BBB-, or better, has agreed to guarantee, assume or, to
the reasonable satisfaction of the Partnership, otherwise become responsible
for such future demand charges payable, then Tatham Offshore would receive a
reassignment of the Assigned Properties upon satisfaction of the Payout Amount.
In the event the Payout Amount has been satisfied but none of the above
conditions have been met, Tatham Offshore is entitled to receive one-third
(1/3) of the revenues, net of operating expenses and platform access and
processing fees, until such time as one of the above conditions is met.

     Flextrend Development initiated production from each of the Assigned
Properties.  As discussed above, the Phar Lap property is currently producing
approximately 90 MMcf per day.  In addition to three producing wells on Garden
Banks Block 72,  which are currently producing approximately 3,600 barrels of
oil and 6.5 MMcf of gas per day, an additional well has been successfully
drilled and is currently being completed. The Garden Banks 117 property is
currently producing approximately 2,500 barrels of oil, 5.0 MMcf of gas and
2,900 barrels of water per day from one well.  Flextrend Development is
currently drilling a second well at Garden Banks Block 117.


                                      50


<PAGE>   53

     In September 1996, Tatham Offshore entered into the Drilling Arrangement
with Sedco Forex.  The Drilling Arrangement includes the use of the FPS Bill
Shoemaker and will become effective upon the mobilization of the rig to Tatham
Offshore's initial location.  The initial contract term of the Drilling
Arrangement is for 90 days or, if sooner, the completion of Tatham Offshore's
initial drilling operation and the mobilization of the rig to another location.
Tatham Offshore may, at its option, extend the initial contract term through
(i) three successive one well options or (ii) two successive one year terms.
Under the terms of the Drilling Arrangement, Tatham Offshore has committed to
pay Sedco Forex a drilling rate of $70,000 per day with a standby rate of
$66,700 per day.  As security for its obligations under the Drilling
Arrangement, Tatham Offshore is required to post an irrevocable letter of
credit or cash collateral of $6.3 million, which amount is equal to the
aggregate operating day rate for the contract term.  In the event that Tatham
Offshore exercises it option to extend the Drilling Arrangement, Tatham
Offshore and Sedco Forex must agree upon additional security for the extension
period.  During the term of the Drilling Arrangement, Tatham Offshore has the
right to sub-contract the rig to other operators.  If the rig is sub-contracted
to another operator, Tatham Offshore will receive the difference between the
sub-contract rate and the above agreed upon rates, if any.  The FPS Bill
Shoemaker is owned by the Company and is operated by Sedco Forex under a charter
agreement.  The Drilling Arrangement is conditioned upon the completion of a
third party financing that will fund certain improvements to the FPS Bill
Shoemaker.  Sedco Forex has the right to substitute a similar drilling rig for
the FPS Bill Shoemaker in the event the FPS Bill Shoemaker is unavailable due to
a previously submitted bid for work offshore Canada.  In the event Sedco Forex
elects to carry out such rig substitution, Tatham Offshore has (i) an option to
use the FPS Bill Shoemaker in the Newfoundland Grand Banks Area rather than the
substitute rig to complete the initial contract term prior to the use by the
third party, subject to availability, and subject to higher contract rates to
account for the additional costs incurred by Sedco Forex as a result of
operations offshore Canada and (ii) an additional option, upon completion of the
third party work and subject to the use of the rig for certain other projects,
to contract to use the rig for the drilling of one well at the then prevailing
contract price.
      
     Tatham Offshore currently intends to fund its operations for the period of
July 1, 1996 through at least June 30, 1997 with cash on hand and cash from
continuing operations.  Although the restructuring of Tatham Offshore's
existing demand charge obligations with the Partnership, the reduction of its
overhead and the initiation of production from the Viosca Knoll Block 817 field
have significantly reduced Tatham Offshore's cash flow deficit, Tatham Offshore
does not anticipate generating positive cash flow prior to the first to occur
of (i) obtaining a refinancing commitment which could allow Tatham Offshore to
reacquire all or a portion of the Assigned Properties from Flextrend
Development, (ii) actual payout of the Payout Amount and the resulting
reversion of all or a portion of the Assigned Properties which Tatham Offshore
anticipates will occur no sooner than the end of fiscal 1998 or (iii) the
initial production from Tatham Offshore's Sunday Silence field.  In order to
initiate production from the Sunday Silence field, Tatham Offshore will require
substantial additional capital to install a production facility and drill
additional development wells.  There can be no assurance, however, that Tatham
Offshore will be able to obtain additional financing on terms that are
acceptable to Tatham Offshore.

     To meet these additional capital needs, Tatham Offshore will continue to
pursue the implementation of its business strategy which will focus primarily
on (i) attempting to develop and initiate production from Tatham Offshore's
Sunday Silence field under a farmout or financing arrangement with an industry
partner or financial institution, (ii) analyzing the results of drilling
operations on the Assigned Properties in an effort to maximize the value of its
reversionary interest and attempting to obtain a financing commitment to
reacquire the properties or, at a minimum, to cause a reduction in the interest
rate utilized in the calculation of the Payout Amount, (iii) attempting to sell
or farmout interests in its other properties, (iv) attempting to reinitiate
production at Genuine Risk (Ship Shoal Block 331) under a farmout arrangement
with an industry partner or, alternatively, selling the property or salvaging
the platform and equipment located at Genuine Risk for sale to a third party or
redeployment on another property, (v) seeking to acquire interests in producing
properties on a carried or financed basis and (vi) pursuing the possible merger
of Tatham Offshore with an industry partner with sufficient capital resources
available to meet the capital requirements for the development of the combined
entity's properties.

     The ability of Tatham Offshore to satisfy its capital needs beyond those
funded with the proceeds from the sale of the Tatham Offshore warrants, Series
A Preferred Stock and any of the Securities offered pursuant to Tatham
Offshore's offering discussed above will depend upon its success in
implementing its business 
                                      51


<PAGE>   54
strategy, particularly its ability to develop and initiate production from the
Sunday Silence field.  Although Tatham Offshore has pursued farmout and outside
financing arrangements for its Sunday Silence project, as of this date, Tatham
Offshore has not been able to obtain an acceptable farmout arrangement with an
industry partner or develop a financing arrangement under the current economic
conditions.  On November 28, 1995, a federal law was enacted that offers
deepwater royalty relief for certain federal leases located in 200 meters or
greater of water depth in the Gulf. The relief provided for in the new law is
not automatic but must be applied for with the Secretary of Interior (or his
delegate).  An applicant must demonstrate that the proposed new production for
which the royalty relief is sought would not be economic to develop absent the
royalty relief.  Tatham Offshore filed an initial application in December 1995
but was advised in late January 1996 that applications could not be accepted in
advance of publication of proposed interim regulations. Proposed interim
regulations were published by the MMS in May 1996.  Tatham Offshore is in the
process of preparing its application for royalty relief for the Sunday Silence
project and anticipates filing such application within the next 30 days.  Under
the new legislation, the first 52.5 million equivalent barrels of oil production
from the Sunday Silence project would be exempt from federal royalties if such
relief is granted. Tatham Offshore believes that if the requested royalty
abatement is granted, the resulting improved economics for the project will be
sufficient to obtain development financing or an industry farmout arrangement.
However, there can be no assurance that Tatham Offshore will be able to obtain
the requested royalty abatement, enter into a farmout or financing arrangement
on favorable terms, that the Sunday Silence field will be successfully developed
or that production will be initiated therefrom on a timely basis, if at all.
                                   
     Tatham Offshore has never paid dividends on its common or preferred stock.
Tatham Offshore expects to retain all available earnings generated by its
operations for the growth and development of its business.

                       REPORT OF INDEPENDENT ACCOUNTANTS


To the Board of Directors and Stockholders of
DeepTech International Inc.


In our opinion, the accompanying consolidated balance sheet and the related
consolidated statements of operations, of cash flows and of stockholders'
equity present fairly, in all material respects, the financial position of
DeepTech International Inc. and its subsidiaries at June 30, 1996 and 1995, and
the results of their operations and their cash flows for each of the three
years in the period ended June 30, 1996, in conformity with generally accepted
accounting principles.  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 of these
statements in accordance with generally accepted auditing standards which
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, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation.  We believe that our audits provide a
reasonable basis for the opinion expressed above.

As discussed in Note 2 to the consolidated financial statements, the Company
changed its method of accounting for income taxes during the year ended June
30, 1994.

NOTE 1 - ORGANIZATION:

DeepTech International Inc. ("DeepTech") is a diversified energy company
engaged, through its operating subsidiaries, in offshore contract drilling
services and the acquisition, development, production, processing,
transportation and marketing of, and the exploration for, oil and gas located
offshore the United States in the Gulf of Mexico (the "Gulf").  DeepTech's
activities are concentrated primarily in the Flextrend (water depths of 600 to
1,500 feet) and Deepwater (water depths greater than 1,500 feet) areas of the
Gulf.

Transportation Services

Leviathan Gas Pipeline Partners, L.P. (the "Partnership"), formed in December
1992, is a publicly held Delaware limited partnership primarily engaged in the
gathering and transportation of natural gas and crude oil through its pipeline
systems located in the Gulf.  The Partnership commenced operations in February
1993 when it succeeded to substantially all of the pipeline operations of
Leviathan Gas Pipeline Company ("Leviathan"), a wholly-owned subsidiary of
Leviathan Holdings Company ("Leviathan Holdings"), an 85%-owned subsidiary of
DeepTech, in connection with the initial public offering of Preference Units
representing limited partner interests in the Partnership.  In June 1994, the
Partnership completed a public offering of an additional 3,000,000 Preference
Units.  The Partnership's assets include interests in (i) eight natural gas
pipeline systems, (ii) a crude oil pipeline system, (iii) five strategically

99%-owned limited liability companies (collectively, the "Operating Companies")
and Tarpon Transmission Company ("Tarpon").  Leviathan, as general partner,
performs all management and operating functions of the Partnership, including
managing each of the Operating Companies and Tarpon.

As of June 30, 1996 and 1995, all the Preference Units were owned by the
public, representing an effective 72.7% limited partner interest in the
Partnership.  Leviathan, through its ownership of all 3,145,947 of the Common
Units of the Partnership, its 1% general partner interest and its approximate

subsidiary of DeepTech at June 30, 1996, is an independent energy company
engaged in the development, exploration and production of oil and gas reserves
located offshore the United States in the Gulf.  Flextrend Development Company,
L.L.C. ("Flextrend Development"), an Operating Company of the Partnership,
acquired Tatham Offshore's working interests, subject to certain reversionary
rights, in three oil and gas properties on June 30, 1995 (Note 10) and is

Offshore Gathering Systems, L.L.C.) ("Manta Ray") and third-party producers.
Manta Ray is an Operating Company of the Partnership.

Deepwater Production Systems, Inc. ("Deepwater Systems") is an 85%-owned
subsidiary of DeepTech at June 30, 1996.  Historically, Deepwater Systems has
provided a variety of deepwater production technology services for DeepTech and
its subsidiaries.  Such services have included sea floor completions and
tie-backs to remote structures, principally for Tatham Offshore, and the
evaluation of floating production system technologies.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

Principles of consolidation

The accompanying consolidated financial statements include the accounts of
DeepTech and those 50% or more owned subsidiaries controlled by DeepTech
(collectively referred to as the "Company"), including Tatham Offshore through
February 14, 1994 and Dover Technology, Inc. ("Dover"), a 50%-owned subsidiary
of DeepTech, through October 31, 1995. In November 1995, Dover began
functioning as an independent business unit and is no longer controlled by
DeepTech.  Mr. Thomas P. Tatham (the Chief Executive Officer, Chairman of the
Board of Directors and principal stockholder of DeepTech), key associates and
management personnel of DeepTech individually own the minority interests in
consolidated subsidiaries at June 30, 1996 and 1995. The Company uses the
equity method to account for its investments in unconsolidated entities in
which the Company owns more than 20% of the voting interests. Losses of equity
investees in excess of DeepTech's investment are recognized to the extent
indebtedness of the equity investee is outstanding to DeepTech.

All significant intercompany balances and transactions have been eliminated in
consolidation.  Certain amounts have been reclassified to conform to the
current year's presentation.

Cash and cash equivalents

All highly liquid investments with a maturity of three months or less when
purchased are considered to be cash equivalents.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)



Debt issue costs

Debt issue costs are capitalized and amortized over the expected life of the
related indebtedness.

Oil and gas properties

The Company accounts for its oil and gas exploration and production activities
using the successful efforts method of accounting.  Under this method, costs of
successful exploratory wells, development wells and acquisitions of mineral
leasehold interests are capitalized.  Production, exploratory dry hole and
other exploration costs, including geological and geophysical costs and delay
rentals, are expensed as incurred. Unproved properties are assessed
periodically and any impairment in value is recognized currently as
depreciation, depletion and amortization expense.  Upon discovery of proved
reserves, the costs of unproved properties are transferred to proved
properties.  Depreciation, depletion and amortization of mineral leasehold
interest costs are computed on the unit-of-production method.
Unit-of-production rates are based on annual estimates of remaining reserves
for each property. Estimated dismantlement, restoration and abandonment costs
and estimated residual salvage values are taken into account in determining
depreciation provisions.  Based on continuing evaluation and other factors,
impairments (additional depreciation and depletion) are recorded to the extent
that the net book value of oil and gas properties, on an overall basis, exceeds
the estimated undiscounted future net revenue of proved oil and gas reserves,
net of income taxes.  Repair and maintenance costs are charged to expense as
incurred; additions, improvements and replacements are capitalized.

Statement of Financial Accounting Standard ("SFAS") No. 121, "Accounting for
the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed
Of",  was issued in March 1995.  SFAS No. 121 requires recognition of
impairment losses on long-lived assets (including proved properties, wells,
equipment and related facilities) if the carrying amount of such assets,
grouped at the lowest level for which there are identifiable cash flows that
are largely independent of the cash flows from other assets, exceeds the
estimated undiscounted future cash flows of such assets.  Measurement of any
impairment loss will be based on the fair value of the assets.  The Company has
adopted SFAS No. 121 effective July 1, 1996.  SFAS No. 121 does not permit
restatement of previously issued financial statements.  The adoption of SFAS
No. 121 did not have a material adverse effect on the Company's financial
condition or results of operations.

Property and equipment

The cost of property and equipment other than drilling rigs and oil and gas
properties is capitalized and depreciated using the double declining balance
method over the estimated useful lives of the assets of three to seven years.
The FPS Bill Shoemaker will be depreciated over its estimated useful life of up
to 30 years.

Capitalization of interest

Interest is capitalized in connection with construction projects as part of the
cost of the asset and is amortized over the related asset's estimated useful
life.

Revenue recognition

Revenue from oil and gas sales is recognized upon delivery in the period of
production and revenue from services is recognized in the period rendered.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)



The Company treats management fees from its unconsolidated subsidiaries as a
reduction of the related expense.  Interest earned on advances to
unconsolidated subsidiaries is recorded as interest income.

Income taxes

In July 1993, the Company adopted SFAS No. 109, "Accounting for Income Taxes"
which changed the Company's method of accounting for income taxes from the
deferred method prescribed by Accounting Principles Board Opinion No. 11,
"Accounting for Income Taxes".  SFAS No. 109 utilizes an asset and liability
approach which requires the recognition of deferred tax assets and liabilities
for the expected future tax consequences of temporary differences between the
carrying amounts and the tax bases of other assets and liabilities.  The
cumulative effect of the accounting change totaled $412,000 for the year ended
June 30, 1994.

Earnings per share

Primary earnings (loss) per share is computed by dividing common equity in net
income (loss) by the weighted average number of common shares and common stock
equivalents outstanding during the period. The weighted average number of
common shares and common stock equivalents outstanding for the years ended June
30, 1996, 1995 and 1994 was 17,168,571, 15,314,646 and 16,609,195,
respectively.

Estimates

The preparation of consolidated financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of certain assets and
liabilities, the disclosure of contingent assets and liabilities at the date of
the consolidated financial statements and the related reported amounts of
revenue and expenses during the reporting period.  Such estimates and
assumptions include those made regarding:  (i) oil and gas reserve disclosure,
(ii) estimated useful lives of depreciable assets and (iii) valuation of
long-term receivables. Actual results could differ from those estimates.
Management believes that the estimates used are reasonable.

Other

The fair values of the financial instruments included in the Company's assets
and liabilities approximate their carrying values.

SFAS No. 123 "Accounting for Stock Based Compensation" was issued in October
1995.  This statement defines a fair value based method of accounting for
transactions in which any entity issues its equity instruments to acquire goods
or services and allows for disclosure of the impact rather than recording the
amount in the Company's consolidated financial statements.  The Company is
required to adopt SFAS No. 123 for transactions entered into during the fiscal
year ending June 30, 1997.  SFAS No. 123 does not require application of its
provisions to equity instruments issued in prior years unless those equity
instruments are modified or settled in cash after the beginning of the fiscal
year in which the standard is adopted.  The Company does not anticipate that
the adoption of SFAS No. 123 will have a material adverse effect on the
Company's financial position or results of operations.

</TABLE>

Additions to property and equipment during the year ended June 30, 1996
primarily related to the acquisition and refurbishment of the FPS Bill
Shoemaker.  See Note 13.  During the years ended June 30, 1996, 1995 and 1994,
the Company capitalized $1,021,000, $2,417,000 and $1,259,000, respectively, of
interest costs related to the acquisition and refurbishment of semisubmersible
drilling rigs.

Substantially all of the Company's oil and gas properties are located in the
Gulf and all of the Company's oil and gas development, production and
exploration activities are conducted by Tatham Offshore and Flextrend
Development.  See Note 14.  The Company's investments in oil and gas properties
at June 30, 1996 and 1995 were comprised primarily of unproved properties.

Asset Held for Sale

In November 1994, the Company acquired a semisubmersible drilling rig, the FPS
Eddie Delahoussaye, for $11,000,000 (Note 6).  Effective March 31, 1995, the
Company transferred the FPS Eddie Delahoussaye to DeepFlex Partners for the
issuance of subordinated payment in kind indebtedness ("PIK Notes") in the
amount of $14,763,000 which was the Company's cost of acquisition and capital
additions through March 31, 1995.  If certain conditions had not been satisfied
by July 1, 1996, the Company would have been obligated to repurchase the rig
for forgiveness of PIK Notes issued for the acquisition, maintenance and
conversion of the rig plus accrued and unpaid interest.  Accordingly, at June
30, 1995, the rig was reflected as an asset held for sale on the accompanying
consolidated balance sheet.

In September 1995, the Company sold the FPS Eddie Delahoussaye (on behalf of
DeepFlex Partners) to Reading & Bates (U.K.) Limited for $18,000,000 which was
comprised of (i) $3,000,000, (ii) 1,232,057 shares of Reading & Bates
Corporation ("Reading & Bates") common stock and (iii) the forgiveness of
$292,000 of trade receivables due Reading & Bates from a wholly-owned
subsidiary of DeepTech.  DeepFlex Partners transferred the net sales proceeds
(including the Reading & Bates common stock) to the Company as repayment of a
portion of the PIK Notes issued by DeepFlex Partners.  The Reading & Bates
common stock was sold for $14,708,000 in October 1995.

NOTE 4 - EQUITY INVESTMENTS:

The Company's investment in the Partnership totaled $3,118,000 and $2,304,000
at June 30, 1996 and 1995, respectively.  The Company's investment in DeepFlex
Partners totaled $1,258,000 at June 30, 1996.

On February 15, 1994, Tatham Offshore issued 5,000,000 shares of common stock
to the public at $10.00 per share (the "Tatham Offshore Offering") reducing
DeepTech's ownership interest in Tatham Offshore from 50% to 40%. As a result
of the Tatham Offshore Offering, DeepTech recorded a pretax gain of $31,758,000
to adjust the carrying value of its investment in Tatham Offshore to 40% of
Tatham Offshore's net equity immediately after the Tatham Offshore Offering.
Effective February 15, 1994, DeepTech accounts for its remaining investment in
Tatham Offshore using the equity method of accounting.  As of June 30, 1996,
the Company owns approximately 39%, 25% and 83% of Tatham Offshore's common
stock, Series A Convertible Exchangeable Preferred Stock ("Series A Preferred
Stock") and warrants, respectively.

The summarized financial information for the Company's investments which are
accounted for using the equity method is as follows:

NOTE 5 - RECEIVABLES FROM AFFILIATES:

Subordinated Convertible Promissory Notes Receivable

As of June 30, 1996, Tatham Offshore had issued to DeepTech $60,000,000
aggregate principal amount of Subordinated Convertible Promissory Notes (the
"Subordinated Notes") for funds received.  The Subordinated Notes bear interest
at a rate of 11 3/4% per annum, payable quarterly in arrears; provided,
however, effective July 1, 1997, interest shall accrue at a rate of 13% per
annum.  Interest income related to these notes totaled $7,060,000, $7,050,000
and $1,508,000 for the years ended June 30, 1996, 1995 and 1994, respectively.
The principal amount of the Subordinated Notes is payable in seven equal annual
installments of approximately $8,571,000 commencing August 1, 1999. At any time
after August 1, 1999, Tatham Offshore may redeem in full, or may from time to
time redeem in part, the Subordinated Notes, without penalty or premium, upon
90 days prior written notice to the holders thereof.  The holders of the
Subordinated Notes have the option at any time to convert all or any portion of
the principal and accrued interest outstanding thereunder into common stock of
Tatham Offshore at a price equal to the initial public offering price of Tatham
Offshore's common stock, $10.00 per share, subject to adjustment under certain
circumstances.  The holders of 20% or more of the principal amount of the
Subordinated Notes and common stock into which Subordinated Notes have been
converted have the right to demand the registration of the Subordinated Notes
(or any shares of common stock issued upon conversion thereof) under the
Securities Act of 1933, as amended; provided, however, that Tatham Offshore
shall only be obligated to file and cause to become effective three
registration statements with respect thereto.  In addition, such holders have
certain piggyback registration rights.  The holders of a majority of the
aggregate principal amount of the Subordinated Notes may accelerate the payment
of the principal and interest thereon upon the occurrence of certain events of
default which include the failure to pay principal or interest when due, the
voluntary or involuntary bankruptcy of Tatham Offshore, unpaid judgment against
Tatham Offshore in excess of $5,000,000 and the acceleration of other
indebtedness of Tatham Offshore in excess of $5,000,000 in the aggregate.  The
Subordinated Notes are subordinate to all senior indebtedness of Tatham
Offshore, which includes the Affiliate Note (Note 10).  Tatham Offshore has
agreed not to incur additional subordinated indebtedness without the consent of
the holders of the Subordinated Notes.

PIK Notes

As of June 30, 1996 and 1995, DeepFlex Partners owed DeepFlex $40,490,000 and
$29,361,000, respectively, aggregate principal amount of PIK Notes which is
included in receivables from affiliates on the accompanying consolidated
balance sheet.  Any additional advances from DeepFlex to DeepFlex Partners are
to be evidenced by PIK Notes.  PIK Notes bear interest at 12% per annum,
payable quarterly, and are due on March 31, 2002.  Interest is required to be
paid under certain circumstances by the issuance of additional PIK Notes.  The
PIK Notes are subordinate to all indebtedness incurred by DeepFlex Partners for
the acquisition, conversion or maintenance of any floating production system
and are secured by a first mortgage on the FPS Laffit Pincay.  Interest income
related to the PIK Notes totaled $5,884,000 for the year ended June 30, 1996.

Highwood Notes

In December 1995, the Company issued promissory notes to Highwood Partners (the
"Highwood Notes") for an aggregate principal amount of $13,500,000 for the
purchase of the FPS Bill Shoemaker.  In connection with the caretakership and
refurbishment of the FPS Bill Shoemaker and FPS V's purchase of Highwood
Partners' 50% interest on June 30, 1996, the Company issued an additional
$3,758,000 of Highwood Notes.  The Highwood Notes are secured by a mortgage on
the FPS Bill Shoemaker and approximately $3,000,000 of PIK Notes,  bear
interest at 12%, payable quarterly and are due March 31, 1997.  The Company
capitalized interest related to the Highwood Notes of $1,021,000 for the year
ended June 30, 1996.  In July 1996, the Company borrowed an additional $992,000
for refurbishment costs bringing the total amount of outstanding Highwood Notes
to $18,250,000.  See Note 10.

In connection with the issuance of the Highwood Notes, the Company granted
Highwood Partners warrants, which expire on December 5, 1997, to acquire
472,973 shares of DeepTech common stock at $5.00 per share.

Term Loan

In February 1996, DeepFlex entered into a term loan agreement to borrow
$12,000,000 (the "Term Loan") from a syndicate of commercial lenders.  The Term
Loan bears interest at 12% per annum, payable monthly, is due on July 15, 1997
and is secured by substantially all tangible and intangible assets currently
owned by DeepFlex, including 5,329,043 Tatham Offshore warrants, 4,670,957
shares of Series A Preferred Stock and all PIK Notes issued by DeepFlex
Partners, except the $3,000,000 of PIK Notes pledged to Highwood

Partners.  In addition, the lenders required an assignment by DeepFlex of the
first preferred ship mortgage on the FPS Laffit Pincay which is securing the
PIK Notes.  In connection with the Term Loan, DeepTech issued to the lenders
warrants to purchase an aggregate of up to 2,666,667 shares of DeepTech common
stock at $4.50 per share.  One of the lenders, Citibank, N.A., required that
Mr. Tatham guarantee $6,000,000 of the Term Loan.  In exchange for Mr. Tatham
agreeing to guarantee a portion of the Term Loan, Mr. Tatham received from
Citibank, N.A. warrants to purchase 333,333 shares of DeepTech common stock,
twenty-five percent of the loan fees payable by the Company to Citibank, N.A.
and a quarterly fee equal to 50 basis points per annum for the period the
guaranty is outstanding.  Proceeds from the Term Loan were utilized to repay
$3,492,000 of the Short-Term Notes, discussed below, for expenses incurred in
connection with the Term Loan and for working capital and general corporate
requirements.  DeepFlex is required to make monthly principal payments equal to
its excess cash flow as defined in the Term Loan agreement beginning in October
1996.  DeepFlex incurred debt issue costs of $728,000 in connection with the
Term Loan which are being amortized over the life of the indebtedness.
Interest expense and amortization of debt issue costs related to the Term Loan
for the year ended June 30, 1996 totaled $783,000.

Senior Notes

In March 1994, DeepTech completed a public offering of $82,000,000 of 12%
senior secured notes (the "Senior Notes") due December 15, 2000.  Interest on
the Senior Notes is payable semi-annually in arrears on June 15 and December 15
of each year at a rate of 12% per annum.  The Senior Notes are secured by a
security interest in and pledge of substantially all of DeepTech's material
assets including all of the outstanding capital stock held or acquired by
DeepTech in each of its subsidiaries as well as all of the Subordinated Notes
held or acquired by DeepTech and any securities into which or for which such
Subordinated Notes may be converted or exchanged pursuant to their terms.  The
Senior Notes may be redeemed at the option of DeepTech, in whole or in part, at
any time on or after June 15, 1999 at 106% of their principal amount, plus
accrued interest, and at 100% of such principal amount, plus accrued and unpaid
interest, to the date of redemption from and after June 15, 2000.
Notwithstanding the foregoing, at any time on or before March 21, 1997,
DeepTech may also redeem up to 30% of the Senior Notes with a portion of the
net proceeds from an initial public offering of equity securities, provided
such redemption occurs within 120 days after such initial public offering, in
whole or in part, at a redemption price equal to 111 1/2% of the principal
amount of such Senior Notes, plus accrued and unpaid interest to the redemption
date.  Interest expense and amortization of debt issue costs related to the
Senior Notes totaled $10,731,000, $10,705,000 and $2,946,000 for the years
ended June 30, 1996, 1995 and 1994, respectively. DeepTech issued the Senior
Notes at a 2.278% discount of $1,868,000 and this discount is being amortized
to interest expense over the life of the debt.  For the years ended June 30,
1996, 1995 and 1994, interest expense includes $222,000, $197,000 and $52,000,
respectively, of amortization of this bond discount.  The effective interest
rate for the years ended June 30, 1996, 1995 and 1994 was 12.5%.

The Indenture governing the Senior Notes limits the ability of DeepTech to
incur additional indebtedness, subject to certain exceptions, and provides that
upon a Change of Control, Partnership Leverage Event or Tatham Conversion Event
(each defined therein), DeepTech is required to offer to purchase the Senior
Notes at 101%, 100% and 101%, respectively, of the principal amount thereof,
plus accrued and unpaid interest to the date of purchase.  In addition, the
Indenture provides that if DeepTech's Asset Coverage Ratio (defined therein)
falls below 2.0 to 1.0, DeepTech is required to offer to repurchase at 100% of
the principal amount thereof, plus accrued and unpaid interest, if any, an
amount of Senior Notes sufficient to increase the Asset Coverage Ratio to not
less than specified levels.  At June 30, 1996, the Company's Asset Coverage
Ratio was 2.7 to 1.0.

Wilrig AS promissory notes

In November 1994, the Company acquired from Wilrig AS ("Wilrig") a
semisubmersible drilling rig, the Treasure Driller, which the Company renamed
the FPS Eddie Delahoussaye (Note 3).  In connection with the acquisition of the
FPS Eddie Delahoussaye, DeepTech obtained an option to acquire the FPS Bill
Shoemaker (Note 1) from Wilrig.  As consideration, the Company issued to Wilrig
(i) promissory notes in the aggregate principal amount of $11,000,000 due
December 1997 and (ii) warrants which grant Wilrig the right to exchange the
principal and interest outstanding under the promissory notes for common stock
of DeepTech at the rate of $10.00 per share up to a maximum of 1,100,000
shares.  Interest expense related to this debt is payable quarterly at 10% per

1995, respectively.

Notes payable to affiliates

In December 1995 and January 1996, DeepTech paid $300,000 in principal of the
notes payable to affiliates due on January 1, 1996.  In January 1996, the
Company issued $10,087,000 in unsecured notes payable (the "Short-Term Notes")
bearing interest at 18% per annum and due on February 15, 1996 to affiliates in
settlement of the remaining $6,672,000 of principal and $3,415,000 of interest
which was due on January 1, 1996.

In February 1996, DeepTech refinanced $6,640,000 of Short-Term Notes in the
form of subordinated unsecured notes issued by DeepTech to affiliates (the
"DeepTech Subordinated Notes") and guaranteed by DeepFlex on a subordinated
basis to the Term Loan.  The DeepTech Subordinated Notes are due January 15,
1997 and bear interest at 15% per annum, payable quarterly.  In connection with
this refinancing, these affiliates received a 4% refinancing fee of $266,000
and warrants to purchase 1,475,555 shares of DeepTech common stock at $4.50 per
share.  Interest expense and amortization of debt issue costs related to the
DeepTech Subordinated Notes totaled $370,000 and $133,000, respectively, for
the year ended June 30, 1996.

NOTE 7 - MINORITY INTERESTS IN CONSOLIDATED SUBSIDIARIES:

Leviathan Gas Pipeline Company

During the years ended June 30, 1996, 1995 and 1994, Leviathan paid $7,707,000,
$2,009,000 and $13,000,000, respectively, in dividends to its common
stockholders. DeepTech, through Leviathan Holdings, owns an effective 85%
interest in Leviathan.

Tatham Offshore, Inc.

During the year ended June 30, 1994, Tatham Offshore redeemed all of its then
outstanding convertible redeemable preferred stock for $5,035,000 with proceeds
advanced by DeepTech.  The obligation included a redemption premium in excess
of the cumulative undeclared dividends. This premium of $600,000 was treated as
an adjustment to additional paid- in capital and represents the difference
between the net income and the net income attributable to common stockholders
for the year ended June 30, 1994.

NOTE 8 - STOCKHOLDERS' EQUITY:

On March 28, 1994, DeepTech filed a Registration Statement on Form S-1 (the
"Shelf Registration Statement") with the Securities Exchange Commission in
connection with the public offering by selling stockholders of 18,332,722
shares of common stock of DeepTech which was declared effective on April 13,
1994.  Sales of common stock under the Shelf Registration Statement were
suspended in January 1995 pending preparation of an amendment thereto.

In connection with the original acquisition financing for the FPS Laffit
Pincay, which was sold to DeepFlex Partners in March 1995, the Company had
granted a 25% net profits interest in the economic profits from the sale,
lease, charter or other operation of the semisubmersible rig to the noteholder.
The estimated net present value of such consideration was recorded as debt
issue costs at the time of the acquisition.  In late 1995, the parties agreed
to the full, final and complete resolution of all claims arising out of the
loan agreement.  In exchange for releasing and forever discharging the Company
from any obligations under the loan agreement, the noteholder received $300,000
and 125,000 shares of DeepTech common stock valued as of November 30, 1995.
Final closing, settlement and payment was completed on February 5, 1996.
DeepFlex Partners issued additional PIK Notes to DeepFlex to reimburse its

In December 1994, the Company agreed to charter a multi-purpose service vessel
for use in the Gulf from Alpha Marine Services (the "Edison Chouest Agreement")
for a two-year period commencing in May 1995 with an option to extend the
charter for up to an additional 13 years. In return, the Company agreed to pay
an initial base day rate of $6,980 as a charter fee for use of the vessel.  The
Company executed an agreement with Alpha Marine Services effective October 1,
1995 to terminate the Edison Chouest Agreement in exchange for the issuance by

 (a)     Includes warrants to purchase 337,938 shares of DeepTech common stock
         which expired in July 1995; however, on September 8, 1995, the Board
         of Directors of DeepTech resolved to offer the option to extend these
         warrants through February 19, 1998 if one-half of these warrants were
         exercised by October 1, 1995.
 (b)     Certain options previously issued to directors subject to shareholder
         approval were repriced during the year ended June 30, 1996 in
         connection with approval of the Company's Non-Employee Director Stock
         Option Plan by its shareholders.

Included in the warrants outstanding at June 30, 1996 are 2,103,752 and
1,050,000 nonqualified stock options issued pursuant to the Amended Equity
Incentive Plan (the "Option Plan") and the Company's Non-Employee Director
Stock Option Plan (the "Director Plan"), respectively.  See Note 10. Options to
purchase a maximum of 4,000,000 shares of DeepTech common stock may be issued
pursuant to the Option Plan which is administered by the DeepTech Board of
Directors (the "Board").  The Company may issue options to purchase a maximum of
2,000,000 shares of DeepTech common stock pursuant to the Director Plan.  In
June 1996, the Company issued 99,066 shares of common stock to outside
directors pursuant to the exercise of options granted under the Director Plan
in settlement of directors fees and meeting attendance fees for the year ended
June 30, 1996.

In connection with an extension of the initial maturity date of DeepTech
indebtedness in May 1990, certain noteholders received warrants to purchase
502,419 shares of DeepTech common stock.  During the year ended June 30, 1994,
two noteholders exercised options to purchase a combined 108,457 shares of
DeepTech common stock at the exercise price of $3.41 per share.  In July and
September 1994, respectively, a noteholder and Mr. Tatham exercised options to
purchase 1,466 and 304,558 shares, respectively, of DeepTech common stock at
the exercise price of $3.41 per share.

Additionally, in connection with a borrowing during the year ended June 30,
1994, two noteholders were issued 875,000 warrants to purchase DeepTech common
stock at $4.00 per share exercisable until December 15, 1998, unless the
noteholders elected, on or before December 15, 1995, to surrender the warrants
and receive an additional 10% per annum of interest on the notes for the period
the notes were outstanding.

Interest payable at June 30, 1995 included $626,000 relating to the potential
interest payable under these notes. In December 1995, as the warrants were not
surrendered, interest expense was reduced by $626,000.

In 1988, DeepTech's predecessor company issued subordinated promissory notes
due January 1, 1996 totaling $3,000,000 to Mr. Tatham and a company in which
Mr. Tatham owned an equity interest for the knowledge they had gained through
past financing of research and development activities, including the study of
various deepwater production systems, and to prevent these two entities from
entering into business arrangements in direct competition with the Company for
a period of nine years.  During the year ended June 30, 1994, this $3,000,000
and the minority stockholders' interests in disproportionate original capital
contributions by DeepTech to its subsidiaries, which constitutes the
distributions in excess of predecessor basis, was reclassified to accumulated
deficit.

For income tax purposes, DeepTech files a consolidated income tax return with
its 80% or more owned subsidiaries.  Dover files a separate company federal

NOTE 10 - RELATED PARTY TRANSACTIONS:

Affiliate receivables/payables

A substantial portion of DeepTech's affiliated indebtedness and interest
payable is due to Mr. Tatham.  Interest expense for the years ended June 30,
1996, 1995 and 1994 was $840,000, $605,000 and $758,000, respectively, related
to the indebtedness due to Mr. Tatham.

In October 1995, DeepFlex entered into a bridge loan agreement (the "Bridge
Loan") with Tatham Offshore whereby DeepFlex agreed to make $12,500,000 of
interim bridge financing available to fund a portion of Tatham Offshore's
working capital and capital requirements.  DeepFlex advanced Tatham Offshore
$8,000,000 under the Bridge Loan.  All indebtedness outstanding under the
Bridge Loan accrued interest at a rate of 15% per annum. Interest income
related to outstanding advances under the Bridge Loan totaled $210,000 for the
year ended June 30, 1996.  The terms of the Bridge Loan required Tatham
Offshore to undertake an equity offering or to implement another refinancing or
asset disposition sufficient to repay the outstanding indebtedness under the
Bridge Loan.  On January 31, 1996, DeepFlex subscribed for the purchase of
10,000,000 Tatham Offshore warrants, pursuant to the exercise of Rights which
had been assigned from DeepTech, at a cost of $5,000,000, which was paid
through the forgiveness of $5,000,000 of principal and interest due under the
Bridge Loan.  In February 1996, Tatham Offshore used $3,100,000 of offering
proceeds to repay the remaining principal and accrued interest outstanding
under the Bridge Loan.

Dover charged Tatham Offshore $601,000, $747,000 and $565,000 for the years
ended June 30, 1996, 1995 and for the period from February 15, 1994 through
June 30, 1994, respectively, for services related to the acquisition,
development, exploration or evaluation of oil and gas properties.  At June 30,
1995, Tatham Offshore owed Dover $1,312,000 for such services.  On November 1,
1995, DeepTech agreed to assume $1,734,000 of Dover's accounts receivable from
Tatham Offshore in exchange for reducing Dover's payable to DeepTech under a
line of credit arrangement for a like amount.  DeepTech then converted the
$1,734,000 of accounts receivable from Tatham Offshore into an unsecured
promissory note (the "Affiliate Note") which bears interest at 14.5% per annum.
Interest on the Affiliate Note is payable quarterly, beginning March 31, 1996.
The principal is due and payable in six monthly installments, beginning on a
date which is the earlier of (i) November 1, 1997 or (ii) the last day of the
calendar month in which Tatham Offshore receives proceeds from the issuance of
any preferred stock in an amount equal to or greater than $20,000,000.
Interest income related to the Affiliate Note totaled $170,000 for the year
ended June 30, 1996.

                  DEEPTECH INTERNATIONAL INC. AND SUBSIDIARIES
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)



In January and April 1995, an officer/director of DeepTech executed unsecured,
non-interest bearing demand notes in favor of DeepTech for $100,000 and
$300,000, respectively.  Additionally, in June 1995, DeepTech granted stock
options to purchase 300,000 shares of its common stock to this officer/director
at an exercise price of $4.00 per share.  The options were exercised on June
12, 1995 in exchange for a note payable to DeepTech in the aggregate amount of
$1,200,000, bearing interest at 8% per annum, principal and interest due on
June 12, 1998.  This note will be canceled by DeepTech if the officer/director
continues to be employed by DeepTech for three years from the date of grant.
If the officer/director voluntarily terminates employment with DeepTech prior
to the end of the three-year period from the date of grant, the
officer/director must repay the note by either (i) paying principal and
interest or (ii) returning the stock to DeepTech to satisfy repayment of
principal and interest.  The note receivable is reflected as a reduction of
stockholders' equity as of June 30, 1996 and 1995.  General and administrative
expenses for the year ended June 30, 1996 includes $400,000 of compensation
expense related to this note receivable.

On March 31, 1994, Mr. Tatham executed an unsecured demand note in favor of
DeepTech for $350,000 bearing interest at 15% per annum.  This demand note was
paid in full in April 1994.  On August 22, 1994, Mr. Tatham executed an
unsecured demand note in favor of DeepTech for $1,000,000 bearing interest at
15% per annum.  This demand note was paid in full in October 1994.  As of June
30, 1995, Mr. Tatham had executed an unsecured demand note in favor of DeepTech
for $600,000 bearing interest at 15% per annum.  In settlement of an obligation
to Mr. Tatham, DeepTech canceled this demand note in September 1995 as discussed
below.  In October 1995, Mr. Tatham executed an unsecured demand note in favor
of DeepTech for $250,000 bearing interest at 15% per annum.  This demand note
was paid in full in January 1996.

Compensation arrangements

Effective July 1, 1995, DeepTech established three deferred compensation
arrangements:  (i) a mandatory arrangement for Mr. Tatham, (ii) a mandatory
arrangement for certain senior executives of DeepTech and (iii) an optional
arrangement for all other employees of DeepTech.  Pursuant to the terms of each
arrangement, participants deferred all or a portion of their cash salary until
no later than July 1, 1996.  During each month in the deferral period, each
participant was entitled to receive options to purchase a number of shares of
either DeepTech or Tatham Offshore or Preference Units of the Partnership equal
to a percentage (ranging from 100% to 300% times their cash salary) divided by
the lesser of the closing price on June 30, 1995 (DeepTech - $4.00, Tatham
Offshore - $3.50 and the Partnership - $23.75) or the average closing price for
the applicable month.  Options were exercisable only by cancellation of the
participant's cash salary.  Each participant earned credits equal to a
multiple, based on the option elected, of their deferred cash salary.  Any
participant except Mr. Tatham could have received all or a portion of their
salary in cash if they did not elect to exercise any options.  In November
1995, DeepTech terminated the deferred compensation arrangement for all but
three employees of DeepTech.  Mr. Tatham exercised options to purchase 600,125
shares of DeepTech common stock in payment of salary due for the year ended
June 30, 1996.  In addition, other senior executives and employees exercised
options to purchase 127,521 shares of DeepTech common stock and 245,182 shares
of Tatham Offshore common stock through June 30, 1996 in connection with the
deferred compensation arrangements.  As of June 30, 1996, 18,752 options
remained outstanding under the deferred compensation arrangements which were
exercised in July 1996 to purchase an equal number of shares of DeepTech common
stock and 125,961 options had expired unexercised.  As a result of issuing its
common stock, Tatham Offshore received a $360,000 credit against its management
fees payable to DeepTech.

Mr. Tatham provided certain technical, research and management assistance on a
consulting basis to the Company for which he was paid $600,000 for the year
ended June 30, 1994.  In June 1995, Mr. Tatham was awarded a $200,000 bonus,
which the Company allowed him to defer pursuant to the terms of the mandatory
deferred compensation arrangement discussed above.  Accordingly, the Company
accrued $600,000 of

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)



compensation expense payable to Mr. Tatham representing 300% of the bonus
amount for use in the exercise of these options.  In August 1995, Mr. Tatham
exercised options and received 150,000 shares of DeepTech common stock in
payment of this bonus.

In connection with the sale of the FPS Eddie Delahoussaye (Note 3), Mr. Tatham
was awarded a $200,000 bonus which he also deferred pursuant to the terms of
the mandatory deferred compensation arrangement.  In September 1995, Mr. Tatham
exercised options to purchase 150,000 shares of DeepTech common stock in
settlement of this bonus.

In November 1994, the Board authorized DeepTech to reimburse Mr. Tatham for
costs he incurred in connection with agreements he made with each of two
outside directors pursuant to which Mr. Tatham had granted each director
options to purchase 150,000 shares of the common stock of DeepTech held by Mr.
Tatham at his cost with respect thereto.  These options were granted to the two
outside directors in connection with their appointment to the Board.  In
September 1995, the Compensation Committee of the Board authorized DeepTech to
grant Mr. Tatham options to purchase 300,000 shares of DeepTech's common stock
at $5.00 per share, the estimated fair market value at the date of grant, and
to pay Mr. Tatham $705,000 which was settled in part by canceling Mr. Tatham's
obligation under an unsecured demand note in the original principal amount of
$600,000.

In December 1992, as an incentive for employment, DeepTech transferred 5% of
its equity interest in Offshore Marketing to an officer and director of
DeepTech who was then an officer of Offshore Marketing and granted the officer
375,000 warrants, one-fifth of which vest annually through January 31, 1999, to
purchase shares of DeepTech common stock at $4.25 per share.  As of June 30,
1996, the officer had exercised 150,000 of these warrants.

Management agreements

DeepTech has entered into management agreements with each of its subsidiaries,
including Leviathan and Tatham Offshore, pursuant to which each affiliate is
charged an annual management fee in exchange for operational, financial,
accounting and administrative services.  The management fee is intended to
reimburse DeepTech for the estimated costs of the services provided to each
affiliate.  Leviathan, as general partner of the Partnership, is entitled to
reimbursement of all reasonable expenses incurred by it or its affiliates for
or on behalf of the Partnership by Leviathan to DeepTech under a management
agreement.  The Partnership and Tatham Offshore were each charged an annual
management fee equal to 40% of DeepTech's unreimbursed overhead through October
31, 1995.  Effective November 1, 1995, DeepTech redetermined the level of
services provided to each of its subsidiaries and amended the management
agreements with Leviathan and Tatham Offshore to provide for an annual
management fee of 45.3% and 27.4%, respectively, of DeepTech's overhead.  In
addition, in November 1995, Dover began functioning as a stand alone business
unit with its own management and employees and therefore terminated its
management agreement with DeepTech. During the years ended June 30, 1996, 1995
and 1994, Leviathan charged the Partnership $6,068,000, $4,967,000 and
$2,000,000, respectively, of fees payable to DeepTech pursuant to the terms of
the management agreement.  In addition, the management agreement also requires
Leviathan to compensate DeepTech for certain tax liabilities resulting from
additional taxable income allocated to Leviathan as a result of the
Partnership's offering of additional Preference Units and the investment of the
offering proceeds into construction projects. For the year ended June 30, 1996,
Leviathan charged the Partnership $964,000 to compensate DeepTech for this
additional allocated taxable income.  During the years ended June 30, 1996 and
1995 and for the period from February 15, 1994 through June 30, 1994, Tatham
Offshore was charged $4,436,000, $4,967,000 and $1,774,000, respectively, under
its management agreement. On June 30, 1996, DeepFlex exercised 4,670,957 Tatham
Offshore warrants to purchase an equal number of shares of Series A Preferred
Stock at $1.00 per

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)



share by offsetting the then outstanding receivable from Tatham Offshore for
costs allocated under the management agreement by $4,670,957.

Property Acquisition

On June 30, 1995, Flextrend Development entered into a purchase and sale
agreement (the "Purchase and Sale Agreement"), with Tatham Offshore.  Pursuant
to the terms of the Purchase and Sale Agreement, Flextrend Development
acquired, subject to certain reversionary interests, a 75% working interest in
its Viosca Knoll Block 817, a 50% working interest in Garden Banks Block 72 and
a 50% working interest in Garden Banks Block 117 properties (the "Assigned
Properties") for $30,000,000.  Flextrend Development is entitled to retain all
of the revenues attributable to the Assigned Properties until it has received
net revenues equal to the Payout Amount (as defined below), whereupon Tatham
Offshore is entitled to receive a reassignment of its working interests,
subject to reduction and conditions as discussed below.  "Payout Amount" is
defined as an amount equal to all costs incurred by Flextrend Development with
respect to the Assigned Properties (including the $30,000,000 acquisition cost
paid to Tatham Offshore) plus interest thereon at a rate of 15% per annum.
Effective February 1, 1996, the Partnership entered into an agreement with
Tatham Offshore regarding certain transportation agreements that increases the
amount recoverable from the Payout Amount by $7,500,000 plus interest as
discussed below.  As of June 30, 1996, the Payout Amount was $77,698,000
comprised of (i) initial acquisition and transaction costs of $32,089,000, (ii)
development and operating costs of $49,301,000, (iii) prepaid demand charges of
$7,500,000 and (iv) interest of $7,084,000 reduced by net revenue of
$18,276,000.  Tatham Offshore and the Partnership have agreed that in the event
Tatham Offshore furnishes the Partnership with a financing commitment from a
lender with a credit rating of BBB- or better covering 100% of the then
outstanding Payout Amount, the interest rate utilized to compute the Payout
Amount shall be adjusted from and after the date of such commitment to the
interest rate specified in such commitment, whether utilized or not.  At any
time prior to December 10, 1996, Flextrend Development may exercise either of
the following options: (i) to permanently retain 50% of the assigned working
interest in either the Viosca Knoll Block 817 property or the Garden Banks
Block 72/Garden Banks Block 117 or (ii) to permanently retain 50% of the
assigned working interest in all Assigned Properties in exchange for forgiving
25% or 50%, respectively, of the then- existing Payout Amount, exclusive of the
$7,500,000 plus interest added to the Payout Amount in connection with certain
transportation agreements.  In the event Flextrend Development elects to reduce
the Payout Amount, it will become obligated to fund any further development
costs attributable to Tatham Offshore's portion of the working interests, such
costs to be added to the Payout Amount.  Otherwise, any further development
costs will be funded by Flextrend Development on a discretionary basis, such
costs to be added to the Payout Amount. Further, in the event Flextrend
Development forgoes its right to permanently retain a working interest in all
or a portion of the Assigned Properties, it will be entitled to recover from
working interest revenues all future demand charges payable for platform access
and processing, in their inverse order of maturity, prior to any reassignment
to Tatham Offshore.  If however, Tatham Offshore (i) satisfies in full the
future demand charges payable for platform access and processing, (ii) delivers
evidence that it has received a rating of BBB-, or better, from at least two
reputable rating agencies or (iii) delivers evidence that an entity with a
rating of BBB-, or better, has agreed to guarantee, assume or, to the
reasonable satisfaction of the Partnership, otherwise become responsible for
such future demand charges payable, then Tatham Offshore would receive a
reassignment of the Assigned Properties upon satisfaction of the Payout Amount.
In the event the Payout Amount has been satisfied but none of the above
conditions have been met, Tatham Offshore is entitled to receive one-third
(1/3) of the revenues, net of operating expenses and platform access and
processing fees, until such time as one of the above conditions is met.

In September 1995, Tatham Offshore acquired an aggregate 25% working interest
in Viosca Knoll Block 817 and an approximate 12.5% working interest in the
remainder of the Viosca Knoll Unit (collectively, the "Phar Lap Working
Interest") from two industry partners for a total of $16,000,000 in convertible
production





                                      F-24

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)



payments payable from 25% of the net cash flow from the Phar Lap Working
Interest so acquired.  The unpaid portion of the production payments is
convertible into Tatham Offshore common stock at any time during the first five
years at $8.00 per share.  Under certain circumstances, the industry partners
may require DeepTech to purchase the convertible production payments for an
amount equal to 50% of the unrecovered portion thereof.

Transportation, Processing, Platform Access and Marketing Agreements

Tatham Offshore has entered into transportation, processing and platform access
agreements with the Partnership pursuant to a Master Gas Dedication Agreement
in which Tatham Offshore has dedicated all production from its Garden Banks,
Viosca Knoll, Ewing Bank and Ship Shoal properties as well as certain adjoining
areas of mutual interest to the Partnership for transportation.  In exchange,
the Partnership has agreed to install certain pipeline and related facilities
necessary to transport production from the areas and to provide transportation
services with respect to such production.  Tatham Offshore (i) was obligated to
pay demand charge payments for such services, (ii) is obligated to pay
commodity charges, based on the volume of oil and gas transported or processed
and (iii) effective July 1995, is obligated to pay platform access fees under
these agreements. For the years ended June 30, 1996, 1995 and 1994, the
Partnership charged Tatham Offshore $8,097,000, $8,314,000 and $5,516,000,
respectively, for transportation and platform access services.

Production problems at Ship Shoal Block 331 and reduced oil production from the
Ewing Bank 914 #2 well have affected Tatham Offshore's ability to pay the
demand charge obligations under agreements relative to these properties.  As a
result, effective February 1, 1996, Tatham Offshore entered into an agreement
with the Partnership to prepay all remaining demand charge payments under the
transportation agreements covering Tatham Offshore's Ewing Bank and Ship Shoal
properties.  Under these agreements, Tatham Offshore's demand charge
obligations relative to the Ewing Bank Gathering System and the pipeline
facilities constructed by the Partnership for its Ship Shoal property have been
paid in full.  In exchange, Tatham Offshore has (i) issued to the Partnership
7,500 shares of its 9% Senior Preferred Stock with a liquidation preference of
$1,000 per share, (ii) added the sum of $7,500,000 to the Payout Amount under
the Purchase and Sale Agreement and (iii) granted to the Partnership certain
rights to acquire the Ship Shoal Block 331 platform.  Each share of the 9%
Senior Preferred Stock is senior in liquidation preference to all other classes
of Tatham Offshore stock and has a 9% cumulative dividend, which is payable
quarterly, and shall cumulate to the extent not paid.  The Partnership has made
an irrevocable offer to Tatham Offshore to sell all or any portion of the 9%
Senior Preferred Stock to Tatham Offshore or its designee at a price equal to
$1,000 per share, plus interest thereon at 9% per annum less the sum of any
dividends paid thereon.  In the event Tatham Offshore does not purchase the 9%
Senior Preferred Stock on or before September 30, 1998, then for a period of 90
days thereafter it shall be convertible into Series A Preferred Stock.  The
conversion ratio shall be equal to (i) the liquidation preference plus
accumulated but unpaid dividends divided by (ii) the arithmetic average of
closing prices for the 20 trading days following October 1, 1998 of Series A
Preferred Stock.  The Partnership has the right to utilize the Ship Shoal Block
331 platform and related facilities at a rental rate of $1.00 per annum for
such period as the platform is owned by Tatham Offshore and located on the Ship
Shoal Block 331, provided such use does not interfere with lease operations or
other activities of Tatham Offshore.  In addition, the Partnership has a right
of first refusal relative to a sale of the platform. Tatham Offshore remains
obligated to pay the commodity charges under these agreements as well as all
platform access and processing fees associated with the Viosca Knoll Block 817
property.

Offshore Marketing purchases substantially all oil and gas production of Tatham
Offshore and the Partnership. Through October 1995, Offshore Marketing's
agreement with Tatham Offshore provided for a sales price that was based on
contractually agreed upon posted prices.  In November 1995, Offshore
Marketing's agreement with Tatham Offshore was renegotiated to provide Offshore
Marketing fees equal to 2% of the sales value of crude oil and condensate and
$0.015 per dekatherm of natural gas.  In July 1994 and December 1995,

Offshore Marketing began purchasing substantially all of the oil and gas
production of Manta Ray and Flextrend Development on the same terms as the
renegotiated Tatham Offshore contract.

Offshore Marketing's oil and gas purchases from affiliates are as follows:

As of July 1, 1996, Elliott Associates, L.P., Westgate International, L.P. and
Martley International, Inc., which are entities under common control with
Highwood Partners, had acquired a total of 6,037,784 shares of Series A
Preferred Stock.  During the year ended June 30, 1996, in connection with its
acquisition and financing of the FPS Bill Shoemaker, the Company entered into
certain transactions with Highwood Partners.  See Notes 1 and 6.

During the period from November 1994 through April 1995, the Company
periodically leased, on an hourly basis, an aircraft from Tatham Aviation
Services, Inc. ("Tatham Aviation") for business purposes.  During November 1994
through May 1995, Tatham Aviation charged the Company $482,000 for the use of
the aircraft.  Mr. Tatham is the sole shareholder, Chairman of the Board and
Chief Executive Officer of Tatham Aviation.

In February 1996, DeepFlex Partners' FPS Laffit Pincay began providing contract
drilling services to Flextrend Development, which will extend until Flextrend
Development completes the drilling of the Garden Banks Block 117 #2 well.
During the year ended June 30, 1996, DeepFlex Partners provided services
totaling $1,081,000 under this agreement.  Net proceeds from the contract
drilling services have been used to pay interest and principal to DeepFlex on
the PIK Notes.

In connection with the Tatham Offshore Offering and the exchange of outstanding
indebtedness for Subordinated Notes, DeepTech transferred its 5% working
interest in certain oil and gas properties to Tatham Offshore for $1,444,000
and other consideration.  These properties were transferred at DeepTech's
historical cost basis of $1,000,000 and the remainder of the consideration
received ($444,000) was recorded as a credit to stockholders' equity during the
year ended June 30, 1994.

During the year ended June 30, 1993, Deepwater Systems entered into a turnkey
contract providing for a fixed fee of $16,000,000 with a wholly owned
subsidiary of Leviathan, to construct and install gathering lines and related
facilities to establish and transport natural gas and condensate production
from Tatham Offshore's Ewing Bank 914 #2 well.  One of the Operating Companies
of the Partnership was successor in interest to the turnkey contract and
related construction in progress. The gathering lines and related facilities
were successfully completed and production was established from the Ewing Bank
914 #2 well in August 1993 at a cost to Deepwater Systems of approximately
$18,682,000. During the year ended June 30, 1993, Deepwater Systems recognized
an estimated cost overrun ($3,500,000) incurred pursuant to the turnkey
contract.  During the year ended June 30, 1994, Deepwater Systems completed the
construction and adjusted the estimated cost overrun to actual resulting in an
$818,000 credit to other expenses.

NOTE 11 - COMMITMENTS AND CONTINGENCIES:

Certain of DeepTech's affiliated companies will need substantial additional
capital in order to implement their business strategies and to meet their debt
service requirements and other long-term obligations.  There can be no
assurances, however, that DeepTech or these subsidiaries will be able to raise
capital on terms it deems acceptable, if at all.  Further, DeepTech's Senior
Note Indenture contains covenants that, among other things, require DeepTech to
meet certain collateral coverage tests and restrict the ability of DeepTech to
incur additional indebtedness, effect certain asset sales and engage in certain
mergers or similar transactions.

Tatham Offshore has substantial future capital expenditures associated with the
full development of its oil and gas properties.  Realization of the full
potential of Tatham Offshore's properties is dependent upon its ability to
obtain sufficient additional capital or project financing.

In August 1995, Tatham Offshore formed a wholly-owned subsidiary, Tatham
Offshore (Jersey) Ltd. ("TOJ"), to pursue certain international opportunities.
TOJ is in the process of attempting to obtain offshore concessions from the
government of Nigeria.  There are no assurances that TOJ will be granted a
concession or the terms and conditions that would apply to a concession if
granted.

The Company leases certain office space.  Rental expense for the years ended
June 30, 1996, 1995 and 1994 totaled $861,000, $830,000, and $684,000,
respectively.  Minimum net lease commitments under significant operating leases

In the ordinary course of business, the Company is subject to various laws and
regulations.  In the opinion of management, compliance with existing laws and
regulations will not materially affect the financial position or the results of
operations of the Company.  Various legal actions which have arisen in the
ordinary course of business are pending with respect to the assets of the
Company.  Management believes that the ultimate disposition of these actions,
either individually or in the aggregate, will not have a material adverse
effect on the consolidated financial position or operations of the Company.

NOTE 13 - SUBSEQUENT EVENTS (UNAUDITED):

In July 1996, the Company accepted a commitment from an investment banking firm
to underwrite and syndicate a senior secured credit facility in the aggregate
amount of up to $55,000,000.  Proceeds from the credit facility, which will be
made available to RIGCO North America, L.L.C. ("RIGCO"), a newly formed
indirect subsidiary of DeepFlex, will be used to acquire the FPS Bill Shoemaker
and perform significant upgrades and repairs to the rig.  RIGCO intends to
acquire the FPS Laffit Pincay from DeepFlex Partners for the assumption of the
PIK Notes.  The credit facility will (i) mature in two years, (ii) bear
interest at the prime rate plus 3% per annum, (iii) be secured by all tangible
and intangible assets of RIGCO including the two semisubmersible drilling rigs
and (iv) require a quarterly principal payment of excess cash flow as defined
in the credit agreement with a minimum principal amortization of $250,000 per
quarter.  The credit facility remains subject to the negotiation and execution
of definitive documents.

NOTE 14 - OIL AND GAS PROPERTIES:

The Company has incurred immaterial costs for oil and gas property acquisition,
exploration and development activities, whether capitalized or expensed at the

Supplemental Oil and Gas Information (unaudited):

At June 30, 1996, 1995 and 1994, substantially all of the Company's oil and gas
reserves are owned by Tatham Offshore and the Partnership through Flextrend
Development. DeepTech's interest in proved reserves and standardized measure of
discounted future net cash flows as of June 30, 1996, 1995 and 1994 is shown

Estimates of Tatham Offshore's and the Partnership's reserves at June 30, 1996
have been made by the independent engineering consulting firms, Ryder Scott
Company Petroleum Engineers and Netherland & Sewell Associates, Inc. and the
Partnership's reservoir engineers, respectively.  Net proved reserves are the
estimated quantities of crude oil and natural gas which geological and
engineering data demonstrate with reasonable certainty to be recoverable in
future years from known reservoirs under existing economic and operating
conditions. Estimates of reserve quantities are based on sound geological and
engineering principles but, by their very nature, are still estimates that are
subject to substantial upward or downward revision as additional information
regarding producing and nonproducing fields and technology becomes available.

</TABLE>

The standardized measure of discounted future net cash flows relating to the
Company's interest in Tatham Offshore and the Partnership's proved oil and gas
reserves is calculated and presented in accordance with SFAS No. 69,
"Disclosures about Oil and Gas Producing Activities".  Accordingly, future cash
inflows were determined by applying year-end oil and gas prices to the
Company's interest in Tatham Offshore and the Partnership's estimated share of
future production from proved oil and gas reserves.  Future production and
development costs were computed by applying year-end costs to future years.
Future income taxes were derived by applying year-end statutory tax rates to
the estimated net future cash flows from reserves taking into consideration NOL
carryforwards, where applicable. A prescribed 10% discount factor was applied
to the future net cash flows.

In the Company's opinion, this standardized measure is not a representative
measure of fair market value, and the standardized measure presented for the
Company's proved oil and gas reserves is not representative of the reserve
values.  The standardized measure is intended only to assist financial
statement users in making comparisons between companies.

material respects, the financial position of Leviathan Gas Pipeline Company at
June 30, 1996 and 1995, and the results of its operations and its cash flows for
each of the three years in the period ended June 30, 1996, in conformity with
generally accepted accounting principles.  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 of these statements in accordance with generally accepted auditing
standards which 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

accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation.  We believe that our
audits provide a reasonable basis for the opinion expressed above.

As more fully described in Note 1, the Company, an indirect subsidiary of
DeepTech International Inc., and its affiliates have significant transactions
with DeepTech International Inc. and its affiliates.  Accordingly, the
financial statements of the Company should be read in conjunction with the

                         NOTES TO FINANCIAL STATEMENTS


NOTE 1 - ORGANIZATION:

Leviathan Gas Pipeline Company ("Leviathan"), a Delaware corporation and
wholly-owned subsidiary of Leviathan Holdings Company ("Leviathan Holdings"),
an 85% owned subsidiary of DeepTech International Inc. ("DeepTech"), was formed
in February 1989 to purchase, operate and expand offshore pipeline systems. The
remaining 15% of Leviathan Holdings is principally owned by members of the
management of DeepTech. DeepTech also owns and controls several other
subsidiaries which are engaged in various oil and gas related activities.

In February 1993, Leviathan contributed substantially all of its pipeline
operations to a newly formed master limited partnership, Leviathan Gas Pipeline
Partners, L.P. (the "Partnership"), in connection with the initial public
offering of Preference Units representing limited partner interests in the
Partnership.  In June 1994, the Partnership completed a public offering of an
additional 3,000,000 Preference Units.  The Partnership's assets include
interests in (i) eight natural gas pipeline systems, (ii) a crude oil pipeline
system, (iii) five strategically located multi-purpose platforms, (iv) three
producing oil and gas properties, (v) an overriding royalty interest and (vi) a
dehydration facility.  The Partnership's operating activities are conducted
through twelve approximately 99%-owned limited liability companies
(collectively, the "Operating Companies") and Tarpon Transmission Company
("Tarpon").  Leviathan, as general partner, performs all management and
operating functions of the Partnership, including managing each of the
Operating Companies and Tarpon.

As of June 30, 1996 and 1995, all the Preference Units were owned by the
public, representing an effective 72.7% limited partner interest in the
Partnership.  Leviathan, through its ownership of all 3,145,947 of the Common
Units of the Partnership, its 1% general partner interest and its approximate
1% nonmanaging interest in certain of the Operating Companies, owned an
effective 27.3% interest in the Partnership as of June 30, 1996 and 1995.

NOTE 2 - SIGNIFICANT ACCOUNTING POLICIES:

Revenue recognition

Leviathan treats management fees from its unconsolidated subsidiary as a
reduction of the related expenses.

Income taxes

Leviathan's results are included with its parent, DeepTech, in a consolidated
federal income tax return. DeepTech and its subsidiaries that are part of the
consolidated tax group, including Leviathan, are parties to intercompany tax
sharing agreements which describe the method of determining the intercompany
charge for income taxes.  Under its tax sharing agreement, Leviathan is to
calculate a provision for income taxes equal to that which would be calculated
if Leviathan filed a separate income tax return.  Tax loss and other tax
benefit carryforwards, except those subject to certain limitations, are
similarly calculated for Leviathan on a separate return basis.  Federal income
taxes currently payable are remitted to DeepTech and state income taxes are
remitted to the applicable state taxing authorities.

                  NOTES TO FINANCIAL STATEMENTS - (CONTINUED)




In July 1993, Leviathan adopted Statement of Financial Accounting Standard
("SFAS") No. 109, "Accounting for Income Taxes", which changes the method of
accounting for income taxes from the deferred method prescribed by Accounting
Principles Board Opinion No. 11, "Accounting for Income Taxes".  SFAS No. 109
utilizes an asset and liability approach which requires the recognition of
deferred tax assets and liabilities for the expected future tax consequences of
temporary differences between the carrying amounts and the tax bases of other
assets and liabilities.  The cumulative effect of the accounting change totaled
$57,000 for the year ended June 30, 1994.

Estimates

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 certain assets and liabilities, the
disclosure of contingent assets and liabilities at the date of the financial
statements and the related reported amounts of revenue and expenses during the
reporting period.  Actual results could differ from those estimates.
Management believes that the estimates used are reasonable.

Other

The fair values of the financial instruments included in Leviathan's assets and
liabilities approximate their carrying values.

NOTE 3 -  EQUITY INVESTMENT:

Leviathan's investment in the Partnership totaled $3,118,000 and $2,304,000 at
June 30, 1996 and 1995, respectively.  The summarized financial information for
Leviathan's investment which is accounted for using the equity method is as
follows:

(a) Leviathan's effective ownership in the Partnership includes its interest in
    the Operating Companies and approximates 35.8% for the period from February
    19, 1993 through June 27, 1994.  After June 27, 1994, Leviathan's effective
    ownership in the Partnership approximates 27.3%.

The Partnership and its Operating Companies will distribute 100% of available
cash, as defined, on a quarterly basis to the holders of the Preference Units
and to Leviathan, as general partner and holder of the Common Units.

NOTE 4 - STOCKHOLDERS' EQUITY:

Leviathan has authorized a total of 5,000,000 shares of $.01 par value,
redeemable cumulative preferred stock, which bears a cumulative dividend of
14%, and 500,000 shares of Class B, which bears a cumulative dividend of 10%.
Both classes of preferred stock were redeemable by Leviathan at its option upon
payment of $10 per share and all accrued and unpaid dividends.  At June 30,
1996 and 1995, none of this preferred stock is issued or outstanding.

During the years ended June 30, 1996, 1995 and 1994, Leviathan paid $7,707,000,
$2,009,000 and $13,000,000 respectively, in dividends to its common
stockholders.

NOTE 5 - INCOME TAXES:

Leviathan has been and will be included in the consolidated federal income tax
returns filed by DeepTech. Leviathan and DeepTech have entered into a tax
sharing agreement providing for the manner of determining payments with respect
to federal income tax liabilities (Note 2).

Deferred federal income taxes are primarily attributable to the differences in
depreciation rates and in the timing of recognizing income from the Partnership
for financial and tax reporting purposes.

The intercompany charges for federal income taxes are as follows:

For the years ended June 30, 1996 and 1995, Leviathan paid DeepTech $1,220,000
and $4,216,000, respectively, pursuant to the tax sharing agreement.  At June
30, 1994, Leviathan owed DeepTech $4,227,000 under this tax sharing agreement
which was paid to DeepTech in August 1994.

NOTE 6 - RELATED PARTY TRANSACTIONS:

Leviathan, as general partner of the Partnership, is entitled to reimbursement
of all reasonable expenses incurred by it or its affiliates for or on behalf of
the Partnership including amounts payable by Leviathan to DeepTech under a
management agreement whereby DeepTech provides operational, financial,
accounting and administrative services to Leviathan.  The management agreement
is intended to reimburse DeepTech for the estimated costs of its services
provided to Leviathan and the Partnership.   During the years ended June 30,
1996, 1995 and 1994, Leviathan charged the Partnership $6,068,000, $4,967,000
and $2,000,000, respectively, of fees payable to DeepTech pursuant to the terms
of the management agreement.  In addition, the management agreement also
requires a payment by Leviathan to compensate DeepTech for certain tax
liabilities resulting from additional taxable income allocated to Leviathan as
a result of the Partnership's offering of additional Preference Units and the
investment of the offering proceeds into construction projects. For the year
ended June 30, 1996, Leviathan charged the Partnership $964,000, which is
included as an offset to general and administrative expenses, to compensate
DeepTech for this additional allocated taxable income.

Prior to July 1, 1994, Leviathan's obligation to DeepTech under the management
agreement was fixed at $2,000,000 annually.  In connection with the closing of
the offering of additional Preference Units in June 1994, Leviathan agreed to
amend the management agreement with DeepTech (effective July 1, 1994) in
consideration for the increase in management services associated with the
Partnership's planned expansion of

facilities. The amended agreement provided for a management fee of $2,000,000 a
year plus 40% of DeepTech's unreimbursed overhead.  Effective November 1, 1995,
the management agreement was amended to reflect the increased management
service associated with the Partnership's new oil and gas drilling activities.
The revised agreement provides for a management fee equal to 45.3% of
DeepTech's unreimbursed overhead.

Leviathan is also entitled to distributions in respect of its general and
limited partner interests in the Partnership and its nonmanaging interest in
the Operating Companies, as well as incentive distributions, if any, in respect
to its general partner interest in the Partnership.

NOTE 7 - COMMITMENTS AND CONTINGENCIES:

In the ordinary course of business, Leviathan is subject to various laws and
regulations.  In the opinion of management, compliance with existing laws and
regulations will not materially effect the financial position of Leviathan.
Various legal actions which have arisen in the ordinary course of business are
pending with respect to the assets of Leviathan.  Management believes that the
ultimate disposition of these actions, either individually or in the aggregate,
will not have a material adverse effect on the financial position or operations
of Leviathan.

NOTE 8 - SUPPLEMENTAL OIL AND GAS INFORMATION (UNAUDITED):

Leviathan's share of the Partnership's costs incurred in oil and gas property,
exploration and development activities, whether capitalized or expensed at the
time these costs were incurred, totaled $12,734,000 and $8,317,000 for the
years ended June 30, 1996 and 1995, respectively.  Leviathan's share of the
Partnership's investments in oil and gas properties at June 30, 1996 and 1995
totaled $20,355,000 and $8,918,000, respectively.  Leviathan's share of the
Partnership's results of operations for oil and gas activities totaled
$2,276,000 and $51,000 for the years ended June 30, 1996 and 1995,
respectively.

At June 30, 1996 and 1995, all of Leviathan's oil and gas reserves are owned by
the Partnership through Flextrend Development. Leviathan's interest in proved
reserves and standardized measure of discounted future net cash flows as of
June 30, 1996 and 1995 is shown net to its effective interest in the
Partnership of 27.3%.

Estimates of the Partnership's reserves at June 30, 1996 have been made by the
independent engineering consulting firm, Netherland & Sewell Associates, Inc.
and the Partnership's reservoir engineers.  Net proved reserves are the
estimated quantities of crude oil and natural gas which geological and
engineering data demonstrate with reasonable certainty to be recoverable in
future years from known reservoirs under existing economic and operating
conditions. Estimates of reserve quantities are based on sound geological and
engineering principles but, by their very nature, are still estimates that are
subject to substantial upward or downward revision as additional information
regarding producing and nonproducing fields and technology becomes available.

         Standardized measure of discounted

</TABLE>

The standardized measure of discounted future net cash flows relating to
Leviathan's interest in the Partnership's proved oil and gas reserves is
calculated and presented in accordance with SFAS No. 69, "Disclosures about Oil
and Gas Producing Activities".  Accordingly, future cash inflows were
determined by applying year-end oil and gas prices to Leviathan's interest in
the Partnership's estimated share of future production from proved oil and gas
reserves.  Future production and development costs were computed by applying
year-end costs to future years.  Future income taxes were derived by applying
year-end statutory tax rates to the estimated net future cash flows from the
Partnership's reserves.  A prescribed 10% discount factor was applied to the
future net cash flows.

In Leviathan's opinion, this standardized measure is not a representative
measure of fair market value, and the standardized measure presented for
Leviathan's proved oil and gas reserves is not representative of the reserve
values.  The standardized measure is intended only to assist financial
statement users in making comparisons between companies.
