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").  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.

The accompanying consolidated financial statements have been prepared without
audit pursuant to the rules and regulations of the Securities and Exchange
Commission. Accordingly, the statements reflect all normal recurring
adjustments which are, in the opinion of management, necessary for a fair
statement of the results of operations for the periods covered by such
statements.  These interim consolidated financial statements should be read in
conjunction with the audited consolidated financial statements and notes
thereto contained in the Company's Annual Report on Form 10-K for the fiscal
year ended June 30, 1996.

Earnings per share

Earnings per share is computed by dividing common equity in net income 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 three months ended December
31, 1996 and 1995 was 20,584,667 shares and 16,331,621 shares, respectively.
The weighted average number of common shares outstanding for the six months
ended December 31, 1996 and 1995 was 20,447,734 shares and 16,114,918 shares,
respectively.

Other

The Company adopted Statement of Financial Accounting Standard ("SFAS") No. 123
"Accounting for Stock Based Compensation" effective July 1, 1996.  SFAS No. 123
encourages entities to adopt the fair value method of accounting for their
stock-based compensation plans.  The adoption of SFAS No. 123 did not have a
material adverse effect on the Company's financial position or results of
operations.  The Company issued 150,000 options during the six months ended
December 31, 1996 pursuant to DeepTech's Non-Employee Director Stock Option
Plan.

Highwood Notes

In December 1995 and June 1996, the Company issued promissory notes to Highwood
Partners (the "Highwood Notes") for an aggregate principal amount of $17.3
million for the purchase of 100% interest in the FPS Bill Shoemaker.  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.  The
Company retired the Highwood Notes in connection with obtaining the RIGCO
Credit Facility discussed below.  The Company capitalized interest related to
the Highwood Notes of $0.6 million for the six months ended December 31, 1996.

Term Loan

In February 1996, DeepFlex entered into a term loan agreement to borrow $12.0
million (the "Term Loan") from a syndicate of commercial lenders.  The Company
retired the Term Loan in connection with obtaining the RIGCO Credit Facility
discussed below.  For the six months ended December 31, 1996, interest expense
related to the Term Loan totaled $0.4 million and debt issue costs amortized in
connection with the repayment of the Term Loan totaled $0.5 million.

RIGCO Credit Facility

On September 30, 1996, RIGCO entered into a $65.0 million senior secured credit
facility with a syndicate of lenders (the "RIGCO Credit Facility").  Proceeds
from the credit facility were used to acquire the FPS Bill Shoemaker as well as
to retire the Highwood Notes and the Term Loan.  A total of $30.9 million of
the proceeds are to be used to fund significant upgrades to the FPS Bill
Shoemaker, the remaining balance of which is currently maintained in a
construction fund collateral account, shown as restricted cash on the
accompanying consolidated balance sheet.  The remaining proceeds of $1.4
million are available for RIGCO's general corporate purposes. RIGCO also

NOTE 5 - STOCKHOLDERS' EQUITY:

Under various agreements and arrangements, DeepTech has authorized the issuance
of stock warrants to noteholders, employees, directors and financial
institutions.  On September 30, 1996, Westgate International, L.P. ("Westgate")
exercised warrants to acquire 472,973 shares of DeepTech common stock at $5.00
per share.  Highwood Partners acquired these warrants in December 1995 in
connection with DeepTech's financing of the acquisition of the FPS Bill
Shoemaker and subsequently assigned such warrants to Westgate.  DeepTech has
agreed to register the shares of common stock acquired by Westgate pursuant to
the warrant agreement.  A registration statement will be filed shortly to
register the common stock acquired by Westgate and certain other common stock.
In December 1996, the Company extended an offer to certain of its
warrantholders whereby the exercise period for certain vested warrants could be
extended for one, two or three years in consideration for the immediate
exercise of 25%, 37.5% or 50%, respectively, of the warrants so designated by
each warrantholder.  As a result of this offer, on December 31, 1996, DeepTech
issued 1,080,701 shares of common stock pursuant to the exercise of warrants at
prices ranging from $4.00 to $4.50 per share and extended the exercise period
on 1,894,446 warrants.  In addition, during the six months ended December 31,
1996, DeepTech issued 28,127 shares of common stock pursuant to the exercise of
other outstanding warrants and options.  At December 31, 1996, DeepTech had
outstanding warrants and options to acquire 9,647,284 shares of common stock.

NOTE 6 - RELATED PARTY TRANSACTIONS:

DeepTech has entered into management agreements with certain of its affiliates,
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.  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.  Effective July
1, 1996, the management agreements with Leviathan and Tatham Offshore were
amended to provide for an annual management fee of 54% and 24%, respectively,
of DeepTech's overhead expenses. During the six months ended December 31, 1996,
the Partnership and Tatham Offshore were charged $3.5 million and $1.6 million,
respectively, under their respective agreements.

During the six months ended December 31, 1996, Leviathan Holdings paid
dividends of $4.0 million to its common stockholders, which included DeepTech
as a result of its 85% ownership interest in Leviathan Holdings.

As of December 31, 1996, DeepTech holds an aggregate principal amount of $60.0
million of Tatham Offshore subordinated convertible promissory notes (the
"Subordinated Notes").  Interest income related to these notes totaled $3.5
million for the six months ended December 31, 1996.

Effective December 10, 1996, Flextrend Development exercised its option to
permanently retain 50% of the assigned working interest in all three of the
Assigned Properties in exchange for forgiving 50% 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 with
the Partnership. Accordingly, Tatham Offshore is entitled to receive a
reassignment of one-half interest in the Assigned Properties (37  1/2% working
interest in Viosca Knoll Block 817, 25% working interest in Garden Banks Block
72 and a 25% working interest in Garden Banks Block 117), subject to conditions
as discussed below, after Flextrend Development has received net revenues equal
to the Payout Amount. Flextrend Development remains 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.  Flextrend
Development's election to retain 50% of the assigned working interest in all
three Assigned Properties reduced the Payout Amount from $94.0 million to $50.8
million.  Subsequent to December 10, 1996, only 50% of the development and
operating costs attributable to the Assigned Properties are added to the Payout
Amount and 50% of the net revenue from the assigned working interests in the
Assigned Properties will reduce the Payout Amount.  As of December 31, 1996,
the Payout Amount was $49.6 million comprised of (a) the sum of (i) initial
acquisition and transaction costs of $32.1 million, (ii) development and
operating costs of $84.6 million, (iii) prepaid demand charges of $7.5 million
and (iv) interest of $13.1 million reduced by (b) the sum of (i) net revenue of
$44.5 million and (ii) forgiveness of $43.2 million of the Payout Amount.

During the six months ended December 31, 1996, substantially all of Offshore
Marketing's oil and gas purchases were derived from purchases from Tatham
Offshore and the Partnership.

In December 1996, DeepFlex exercised 1,016,957 Tatham Offshore warrants to
acquire shares of Tatham Offshore's Series C 4% Convertible Exchangeable
Preferred Stock at $1.00 per share.  The remaining 4,312,086 Tatham Offshore
warrants held by DeepFlex were automatically converted into 4,312,086 shares of
Tatham Offshore's Mandatory Redeemable Preferred Stock on January 1, 1997.

In February 1996, DeepFlex Partners' FPS Laffit Pincay began providing contract
drilling services to Flextrend Development, which will extend until Flextrend
Development concludes the drilling and completion of the Garden Banks Block 117
#2 well.  During the six months ended December 31, 1996, DeepFlex Partners and
RIGCO reported operating revenue totaling $4.4 million and $4.6 million,
respectively, related to these services.  Net proceeds from the contract
drilling services paid to DeepFlex Partners were used to pay interest and
principal to DeepFlex on the PIK Notes.

NOTE 7 - 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, the Company's debt
agreements contain covenants that among other things, require the Company to
meet certain collateral coverage tests and restrict the ability of the Company
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 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 8 - SUBSEQUENT EVENTS:

On January 15, 1997, the Company issued $6.0 million of renewal subordinated
promissory notes (the "Renewal Notes") to Mr. Tatham and paid $640,000 to other
affiliates in settlement of $6,640,000 of Subordinated Promissory Notes which
matured on that date.  On January 23, 1997, DeepTech paid $1,650,000 principal
amount of the Wilrig Notes and issued $15,350,000 aggregate principal amount of
Senior Subordinated Notes (the "Senior Subordinated Notes") to an investment
banking firm in exchange for $9.35 million principal amount of the Wilrig Notes,
1,100,000 warrants to purchase common stock of DeepTech at $10.00 per share (the
"Wilrig Warrants") and $6.0 million of Renewal Notes, all of which were
concurrently purchased by the investment banking firm from the respective
holders thereof.  The Senior Subordinated Notes are unsecured, bear interest at
11%, payable quarterly and are due on May 31, 2000.  The Senior Subordinated
Notes, which are subordinated to the existing Senior Notes and will rank senior
to all subordinated indebtedness of the Company, are not redeemable before June
15, 1999 and thereafter may be redeemed at 101% of the principal amount thereof,
plus accrued interest.  The Company is obligated to make an offer to repurchase
the Senior Subordinated Notes at 101% of the principal amount thereof, plus
accrued interest to the date of repurchase, in the event of a change of control
as defined.  In addition, if the Company is required to make a repurchase offer
with respect to the Senior Notes, it will be obligated to make an offer to
purchase the Senior Subordinated Notes at a repurchase price of 100% of the
principal amount thereof, plus accrued interest, to the extent permitted by the
indenture covering the Senior Notes.  The Company has also agreed to file a
registration statement with respect to the Senior Subordinated Notes upon
request from at least 75% of the holders thereof. The Company reimbursed the
investment banking firm for legal fees and expenses of $60,000 and paid an
underwriting fee of $307,000 in connection with such transaction.

In addition, in conjunction with Mr. Tatham's agreement to sell the Renewal
Notes to the investment banking firm, DeepTech agreed to assign the Wilrig
Warrants to Mr. Tatham and further agreed to provide Mr. Tatham and members of
his immediate family the right, for 90 days, to accept an offer previously made
to certain warrantholders to exercise 25%, 37.5% or 50% of their warrants in
exchange for an extension of one, two or three years, respectively, in the
expiration date of the remaining warrants.  In addition, Mr. Tatham agreed to
waive certain prepayment provisions in the Renewal Notes.

The following discussion is intended to assist in the understanding of the
Company's financial position and results of operations for the three and six
months ended December 31, 1996.

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 and the development and production of oil
and gas reserves from three offshore leases.

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 and offshore eastern Canada.  DeepTech currently owns approximately 37%

284,000 barrels of oil at average prices of $1.85 per Mcf and $17.16 per
barrel, respectively.

Operating expenses for the six months ended December 31, 1996 totaled $2.5
million and included costs to operate the Company's FPS Laffit Pincay
subsequent to its acquisition by RIGCO on September 30, 1996.  Operating costs
for the six months ended December 31, 1995 totaled $0.5 million and included
costs to operate the Company's multi-purpose service vessel and to terminate
the related charter agreement effective October 1, 1995.

Depreciation and amortization totaled $0.5 million for the six months ended
December 31, 1996 as compared with $0.1 million for the six months ended
December 31, 1995.  The increase in depreciation and amortization related to
depreciation of the Company's FPS Laffit Pincay, which was acquired by RIGCO on
September 30, 1996, for the period from October 1, 1996 through December 31,
1996.  Prior to October 1, 1996, the Company conducted its contract drilling
services related to the FPS Laffit Pincay through DeepFlex Partners which
activity is included in equity earnings for the period from July 1, 1996
through September 30, 1996, as discussed above.

Losses of equity investees for the six months ended December 31, 1996 totaled
$0.2 million as compared with $1.4 million for the six months ended December
31, 1995 and related primarily to equity losses of Tatham Offshore.  During the
six months ended December 31, 1996, Tatham Offshore had total operating revenue
of $10.3 million and nonoperating income of $0.2 million.  During the six
months ended December 31, 1996, Tatham Offshore sold 3,279 MMcf of gas and
108,000 barrels of oil at average prices of $2.38 per Mcf and $23.05 per
barrel, respectively.  Tatham Offshore's depreciation and operating expenses
totaled $8.4 million and other expenses totaled $4.2 million for the six months
ended December 31, 1996.  In addition, Tatham Offshore's net income was reduced
by $2.0 million in preferred stock dividends in arrears for the six months
ended December 31, 1996. During the six months ended December 31, 1995, Tatham
Offshore had total operating revenue of $5.2 million and nonoperating income of
$11.3 million which was primarily related to the sale of three properties to
Flextrend Development.  For the six months ended December 31, 1995, Tatham
Offshore sold 715 MMcf of gas and 221,000 barrels of oil at average prices of
$1.97 per Mcf and $17.17 per barrel, respectively. Tatham Offshore's
depreciation and operating expenses totaled $13.3 million and other expenses
totaled $4.0 million for the six months ended December 31, 1995.

General and administrative expenses for the six months ended December 31, 1996
totaled $1.1 million as compared with $2.6 million for the six months ended
December 31, 1995. The decrease in general and administrative expenses was
primarily attributable to decreases in salary and related expenses due to a
reduction in personnel and the restructuring of certain compensation
arrangements.

Operating income for the six months ended December 31, 1996 totaled $6.6
million as compared with operating income of $2.1 million for the six months
ended December 31, 1995.  The change in operating income primarily represented
the net effect of the items discussed above.

Interest and other income for the six months ended December 31, 1996 totaled
$5.1 million as compared with $7.6 million for the six months ended December
31, 1995.  Interest and other income for the six months ended December 31, 1996
included interest income derived from (i) the Subordinated Notes of $3.5
million and (ii) other affiliate debt and available cash of $1.6 million.
Interest and other income for the six months ended December 31, 1995 included
interest income derived from (i) the Subordinated Notes of $3.5 million, (ii)
the PIK Notes payable from DeepFlex Partners of $3.7 million, (iii) interest
earned on available cash of $0.2 million and (iv) other of $0.2 million.

Interest and other financing costs for the six months ended December 31, 1996
totaled $8.2 million as compared with $5.7 million for the six months ended
December 31, 1995.  Interest and other financing costs for the six months ended
December 31, 1996 included (i) interest and amortization of debt issue costs
and discounts related to the Senior Notes of $5.4 million, (ii) interest and
amortization of debt issue costs related to the RIGCO Credit Facility of $0.8
million, (iii) interest related to the Wilrig AS promissory notes of $0.6
million, (iv) interest and amortization of debt issue costs related to the Term
Loan of $0.9 million and (v) interest related to other debt of $0.5 million.
In addition, the Company capitalized $1.6 million of interest costs related to
the RIGCO Credit Facility during the six months ended December 31, 1996 in
connection with the FPS Bill Shoemaker make-ready project.  Interest and other
financing costs for the six

months ended December 31, 1995 included interest and amortization of debt issue
costs and discounts related to the Senior Notes of $5.4 million and $1.0
million of interest expense related to other debt offset by $0.7 million
related to the accounting treatment of interest expense previously recognized
in connection with certain financing arrangements.

During the six months ended December 31, 1996, the Company recorded income tax
expense of $1.2 million as compared with $1.6 million for the six months ended
December 31, 1995.

After taking into account a $0.6 million loss resulting from minority interests
in consolidated subsidiaries, the Company's net income for the six months ended
December 31, 1996 totaled $1.6 million.  For the six months ended December 31,
1995, the Company reported net income of $2.8 million after taking into account
a $0.3 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 Subordinated Notes issued by Tatham Offshore) 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 for
operational, financial, accounting and administrative services.  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 development
stage have been funded through advances by DeepTech to each such Subsidiary,
thereby reducing cash available to DeepTech.

Effective July 1, 1996, DeepTech amended its management agreements with each
Subsidiary and began charging Leviathan, Tatham Offshore, DeepFlex and Offshore
Marketing a management fee equal to 54%, 24%, 18% and 4%, respectively, of
DeepTech's overhead expenses.  Prior to July 1, 1996, DeepTech charged
Leviathan, Tatham Offshore, DeepFlex and Offshore Marketing 45.3%, 27.4%, 18.8%
and 8.5%, respectively, of DeepTech's overhead expenses.  For the six months
ended December 31, 1996, Leviathan, Tatham Offshore 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.  DeepFlex, which is currently charged 18% 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 subsidiaries of the Partnership. For the
quarter ending June 30, 1996, the Partnership increased the quarterly
distribution to $0.70 per Unit.  For the quarter ending September 30, 1996, the
Partnership increased the quarterly distribution to $0.75 per Unit.  In January
1997, the Partnership effected a two for one split of its Preference and Common
Units.  For the quarter ended December 31, 1996, the Partnership increased the
quarterly distribution to $0.40 per Unit ($0.80 per Unit on a pre-split basis).
Leviathan, as general partner, is also entitled to the payment of incentive
distributions if certain target levels of distributions are met.  As a result,
DeepTech's proportionate share of the aggregate distributions paid to Leviathan
for the six months ended December 31, 1996 was approximately $4.4 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 Subordinated Notes issued by Tatham Offshore with an
aggregate principal amount of $60.0 million.  The 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





                                       18
<PAGE>   19
annum. For the six months ended December 31, 1996, interest income under the
Subordinated Notes totaled $3.5 million.  The principal amount of the
Subordinated Notes is payable in seven equal annual installments commencing
August 1, 1999.

In connection with the issuance of the Highwood Notes, DeepTech granted
Highwood Partners warrants to acquire 472,973 shares of DeepTech common stock
at $5.00 per share which warrants were subsequently assigned to Westgate. On
September 30, 1996, Westgate exercised these warrants resulting in $2.4 million
of proceeds to DeepTech. DeepTech has agreed to register the shares of common
stock acquired by Westgate pursuant to the warrant agreement. A registration
statement will be filed shortly to register the common stock acquired by
Westgate and certain other common stock.

In December 1996, the Company extended an offer to certain of its
warrantholders whereby the exercise period for certain vested warrants could be
extended for one, two or three years in consideration for the immediate
exercise of 25%, 37.5% or 50%, respectively, of the warrants so designated by
each warrantholder.  As a result of this offer, DeepTech has issued 1,080,701
shares of DeepTech common stock pursuant to the exercise of warrants to date,
raising proceeds of $4.8 million, and has extended the exercise period on
1,894,446 warrants.

On November 1, 1995, DeepTech agreed to assume $1.7 million of an affiliate's
accounts receivable from Tatham Offshore in exchange for reducing the
affiliates' payable to DeepTech under a line of credit arrangement for a like
amount.  DeepTech then converted the $1.7 million of accounts receivable from
Tahtam Offshore into an unsecured promissory note (the "Affiliate Note") which
bears interest at 14.5% per annum, payable quarterly.  The principal is due and
payable in six monthly installments, beginning on January 31, 1997.

On September 30, 1996, RIGCO entered into the RIGCO Credit Facility for $65.0
million.  Proceeds from the credit facility were used to acquire the FPS Bill
Shoemaker and to perform significant upgrades to the rig as well as to retire
the Highwood Notes and the Term Loan.  RIGCO also acquired the FPS Laffit
Pincay from DeepFlex Partners for the assumption of all of the then outstanding
PIK Notes.  The credit facility (i) is secured by the FPS Laffit Pincay and the
FPS Bill Shoemaker, (ii) bears interest at the prime rate plus 3% per annum,
payable quarterly, (iii) matures September 30, 1998 and (iv) requires a
quarterly principal payment of excess cash flow as defined in the credit
agreement with a minimum principal amortization of $250,000 per quarter
beginning December 31, 1996. RIGCO incurred and capitalized debt issue costs
related to the RIGCO Credit Facility of $3.9 million which are being amortized
over the two-year life of the credit facility.  Interest and amortization of
debt issue costs related to the RIGCO Credit Facility totaled $0.8 million for
the six months ended December 31, 1996.  The Company capitalized interest
related to the RIGCO Credit Facility of $1.6 million during the six months
ended December 31, 1996.  In connection with providing the RIGCO Credit
Facility, syndicate members were issued warrants to purchase an aggregate of 5%
of RIGCO's outstanding equity.

In February 1996, DeepFlex Partners' FPS Laffit Pincay began providing contract
drilling services to Flextrend Development.  The contract will continue until
Flextrend Development completes the drilling of its Garden Banks Block 117 #2
well which should be completed during the third quarter of this fiscal year.
During the six months ended December 31, 1996, DeepFlex Partners and RIGCO
provided services totaling $4.4 million and $4.6 million, respectively, under
this agreement.  Net proceeds from the contract drilling services paid to
DeepFlex Partners through September 30, 1996 were used to pay interest and
principal to DeepFlex on the PIK Notes.  The RIGCO Credit Facility does not
permit payments on the PIK Notes until the credit facility has been repaid.

After completing the drilling contract for Flextrend Development, the FPS
Laffit Pincay is under contract to a major oil company to drill one well in the
Garden Banks area of the Gulf.  This drilling contract includes three one well
options at market prices.

Upon completion of an extensive drilling make-ready upgrade, the FPS Bill
Shoemaker will be mobilized to Canada for a drilling contract with a major oil
company which is a one well program with a one well extension option.  The
drilling make-ready is anticipated to be completed in April 1997.

Uses of Cash.  In December 1996, DeepFlex exercised 1,016,957 Tatham Offshore
warrants to acquire shares of Tatham Offshore's Series C 4% Convertible
Exchangeable Preferred stock at $1.00 per share.  The remaining 4,312,086
Tatham





                                       19
<PAGE>   20
Offshore warrants were automatically converted into 4,312,086 shares of Tatham
Offshore's Mandatory Redeemable Preferred stock on January 1, 1997.  See
"--Tatham Offshore."

On January 15, 1997, the Company issued $6.0 million of Renewal Notes and paid
$640,000 in principal in settlement of $6,640,000 of Subordinated Promissory
Notes payable to affiliates which matured on that date.  On January 23, 1997,
DeepTech paid $1,650,000 principal amount of the Wilrig Notes and issued
$15,350,000 of Senior Subordinated Notes to an investment banking firm in
exchange for $9.35 million principal amount of the Wilrig Notes, $6.0 million of
the Renewal Notes and the Wilrig Warrants which had been concurrently purchased
by the investment banking firm.  The Senior Subordinated Notes are unsecured,
bear interest at 11% per annum, payable quarterly, and are due on May 31, 2000.
The Company reimbursed such firm for legal fees and expenses of $60,000 and paid
an underwriting fee of $307,000 in connection with such transaction.  In
addition, in conjunction with Mr. Tatham's agreement to sell the Renewal Notes
to such firm, DeepTech agreed to assign the Wilrig Warrants to Mr. Tatham and
further agreed to provide Mr. Tatham and members of his immediate family the
right, for 90 days, to accept an offer previously made to certain warrantholders
to exercise 25%, 37.5% or 50% of their warrants in exchange for an extension of
one, two or three years, respectively, in the expiration date of the remaining
warrants. In addition, Mr. Tatham agreed to waive certain prepayment provisions
in the Renewal Notes.

Management expects that the Company's expenditures through December 31, 1997
will include (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 RIGCO Credit Facility of $1.8
million per quarter or $7.3 million on an annual basis and scheduled principal
payments equal to excess cash flow as defined in the credit agreement with a
minimum principal amortization of $250,000 per quarter, (iii) scheduled
interest payments on the Senior Subordinated Notes of $422,000 per quarter, or
$1.7 million on an annual basis and (iv) amounts necessary to pay general and
administrative and other operational expenses.

In addition, the Company anticipates that its capital expenditures for the year
ending December 31, 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.  As of January
31, 1997, the Company has incurred $31.1 million related to the upgrade, repair
and refurbishment program on the FPS Bill Shoemaker. The Company anticipates
that the remaining capital requirements necessary to complete the upgrades on
the FPS Bill Shoemaker will be funded with proceeds from the RIGCO Credit
Facility or from cash on hand.

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 Subordinated Notes and funds provided from the RIGCO Credit
Facility. As of December 31, 1996, the Company had $18.3 million of funds
available, including $12.1 million currently restricted for capital
expenditures related to the FPS Bill Shoemaker.  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. Based on
current projections which assume that the Company receives interest payments on
the Subordinated Notes when due, DeepTech believes that it will have sufficient
funds to meet its anticipated capital needs through at least December 31,1997
and to complete the 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 1998 and
beyond.  These obligations include the repayment by RIGCO of the remaining
balance of the RIGCO Credit Facility which is due is September 1998, the
repayment of DeepTech's Senior Subordinated Note which is due in May 2000 and
the principal balance of $82.0 million under DeepTech's Senior Notes which are
due in December 2000.  The 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
and/or (iv) the exercise of additional 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





                                       20
<PAGE>   21



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
(discussed below).  Net cash provided by operating activities for the year
ended December 31, 1996 totaled $50.3 million. At December 31, 1996, the
Partnership had cash and cash equivalents of $16.5 million.

Cash from continuing operations is derived from (i) payments for transporting
gas through the 100% owned pipelines, (ii) cash distributions from the
Partnership's equity investees which include Stingray Pipeline Company
("Stingray"), High Island Offshore System ("HIOS"), U-T Offshore System
("UTOS"), Viosca Knoll Gathering System ("Viosca Knoll"), Poseidon Oil Pipeline
Company, L.L.C. ("POPCO"), West Cameron Dehydration Company ("West Cameron
Dehy") and effective January 1997, Manta Ray Offshore Gathering Company, L.L.C.
("Manta Ray Offshore") and Nautilus Pipeline Company, L.L.C.  ("Nautilus"),
(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, West Cameron
Dehy, Manta Ray Offshore and Nautilus 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, POPCO and Viosca
Knoll 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 December 31, 1996, Stingray had $23.2 million outstanding under
its term loan agreement and interest accrued at a floating rate of
approximately 6.2% per annum, payable quarterly.

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 December 31, 1996, POPCO
had $84.0 million outstanding under the POPCO Credit Facility bearing interest
at a floating rate of approximately 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.

In December 1996, Viosca Knoll entered into a revolving credit facility (the
"Viosca Knoll Credit Facility") with a syndicate of commercial banks to provide
up to $100.0 million for the addition of compression to the Viosca Knoll
Gathering System and for other working capital needs of Viosca Knoll, including
providing a distribution not to exceed $25.0 million to its partners.  As of
December 31, 1996, Viosca Knoll had $33.3 million outstanding under the Viosca
Knoll Credit Facility bearing interest at a floating rate of approximately
6.69% per annum.  In December 1996, the Partnership received a $12.5 million
distribution from Viosca Knoll as a result of its 50% interest.  Viosca Knoll's
ability to borrow money under the facility is subject to certain customary
terms and conditions, including borrowing base limitations.  The Viosca Knoll
Credit Facility is secured by all of Viosca Knoll's material contracts and
agreements, receivables and inventory and matures on December 20, 2002.

Flextrend Development has initiated production from the each of its oil and gas
properties.  The Viosca Knoll Block 817 project is currently producing a total
of approximately 115 MMcf of gas and 300 barrels of oil per day.  Flextrend
Development owns a 75% working interest in this property, one-half of which is
subject to certain reversionary rights.  The Garden Banks Block 72 lease, which
began producing in May 1996, is currently producing an average of 3,850 barrels
of oil and 15 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 1,750 barrels of oil, 3.5 MMcf of gas and 3,750 barrels of water
per day.  Flextrend Development has drilled a second successful well at Garden
Banks Block 117 which should be placed on





                                       21
<PAGE>   22



production during the first quarter of 1997. Flextrend Development owns a 50%
working interest in each of these properties, one-half of which is subject to
certain reversionary rights.

The Partnership Credit Facility, as amended and restated in December 1996, is a
secured revolving credit facility providing for up to $300.0 million of
available credit subject to certain incurrence limitations.  Proceeds from the
Partnership 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 distributions to the
unitholders. The Partnership Credit Facility can also be utilized to issue
letters of credit as may be required from time to time.  As of December 31,
1996, borrowings totaled $227.0 million under the Partnership Credit Facility
bearing interest at an average floating rate of 6.6% per annum.  There are no
letters of credit currently outstanding under the Partnership 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, including incentive distributions, as applicable,
(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,
(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 completion of drilling
operations on the second well at Garden Banks Block 117.

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.  For the quarter ending June 30, 1996, the
Partnership increased the quarterly distribution to $0.70 per Unit. For the
quarter ending September 30, 1996, the Partnership increased the quarterly
distribution to $0.75 per Unit. In January 1997, the Partnership effected a two
for one split of its Preference and Common Units.  For the quarter ended
December 31, 1996, the Partnership increased the quarterly distribution to
$0.40 per Unit ($0.80 per Unit on a pre-split basis).  This distribution will
be paid on February 14, 1997 to Unitholders of record as of January 31, 1997.
At the current distribution rate of $0.40 per Unit, the Partnership anticipates
making quarterly Partnership distributions of $10.3 million in respect of the
Preference Units, Common Units and general partner interest ($41.3 million on
an annual basis).  The Partnership believes that it will be able to continue to
pay at least the current quarterly distribution of $0.40 per Unit for the
foreseeable future.

In February 1996, Poseidon Pipeline Company, L.L.C. ("Poseidon LLC"), a
subsidiary of the Partnership, and Texaco Trading and Transportation Inc.
("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 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 two phases of the Poseidon Oil Pipeline. In July 1996, Marathon Oil
Company ("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.  The second phase of the
Poseidon Oil Pipeline was placed in service in December 1996.  The Partnership
anticipates that POPCO's future capital requirements will be funded by
borrowings under the POPCO Credit Facility.

In January 1997, the Partnership and affiliates of Marathon and Shell Oil
Company ("Shell") formed Nautilus and Manta Ray Offshore 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 Manta Ray System which was contributed
to Manta Ray Offshore by the Partnership, is approximately $270.0 million.  The
Nautilus system, the new jurisdictional interstate pipeline segment of the
project, will consist of a 30-inch line downstream from Ship Shoal Block 207
connecting to the Exxon Company USA operated Garden City gas processing plant.
Upstream of the Ship Shoal 207 terminal, the 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.
Affiliates of Marathon and Shell have committed to the Nautilus and Manta Ray
systems significant deep





                                       22

water acreage positions in the area, including the recently announced Troika
field (Green Canyon Block 244), and will provide the majority of the capital
funding for the new construction.  The Partnership will provide some funding in
addition to the contribution of the Manta Ray System.

The Partnership anticipates that its total capital expenditures for 1997 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 and Viosca Knoll are anticipated to be funded by borrowings under their
respective credit facilities. Total capital expenditures and equity investments
for 1996 were $101.7 million.

Interest and other financing costs, net of capitalized interest, related to the
Partnership's credit facilities totaled $5.6 million for the year ended
December 31, 1996.  Such amount included commitment fees and amortization of
debt issue costs of $1.2 million. During the year ended December 31, 1996, the
Partnership capitalized $11.9 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 the collection of stock subscriptions
receivable from the exercise of outstanding warrants as of December 31, 1996.
At December 31, 1996, Tatham Offshore had $11.1 million of cash and cash
equivalents and $0.3 million of stock subscriptions receivable.

Cash from continuing operations is derived primarily from production from
Tatham Offshore's Viosca Knoll Block 817 project which is currently producing a
total of approximately 115 MMcf of gas and 300 barrels of oil per day.  Tatham
Offshore currently owns a 25% working interest in the Viosca Knoll Block 817
project which interest is subject to a production payment equal to 25% of the
net operating cash flow from such working interest.

Tatham Offshore also has producing wells at Ewing Bank 914 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.  The Ewing
Bank 914 #2 well is currently producing at a rate of approximately 600 barrels
of oil, 1.2 MMcf of gas and 2,000 barrels of water per day.  The Silent Beauty
project is currently producing at a rate of approximately 6.3 MMcf of gas and
100 barrels of oil per day.

As a result of a rights offering in February 1996, Tatham Offshore received
$12.6 million in gross proceeds ($11.3 million in net proceeds) pursuant to the
exercise of Rights to purchase 25,120,948 Warrants at $0.50 per warrant. As of
January 1, 1997, a total of 20,129,571 Warrants had been exercised to purchase
18,717,030 shares, 74,379 shares and 1,338,162 shares of Series A, B and C
Preferred Stock, respectively, at $1.00 per share which generated an additional
$20.1 million in proceeds to Tatham Offshore.

As of January 1, 1997, there were 4,991,377 Warrants outstanding.  Each Warrant
remaining unexercised at 5:00 p.m. New York time on January 1, 1997 was
automatically converted, without any action on the part of the holder thereof,
into one share of Mandatory Redeemable Preferred Stock, which has a liquidation
preference of $0.50 per share and shall be mandatorily redeemable by Tatham
Offshore under certain circumstances, including from the net proceeds from the
sale of Tatham Offshore common stock pursuant to the exercise of Exchange
Warrants, subject to certain conditions. At any time until December 31, 1998,
each share of Series A, B or C Preferred Stock may be exchanged for four
Exchange Warrants each of which shall entitle 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, the holder of
any shares of Series A, B or C 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 $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 January 31, 1997,
a total of 551,164 shares of Series A Preferred Stock had been converted into
1,283,797 shares of Tatham Offshore common stock.

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

As of December 31, 1996, Tatham Offshore had $60.0 million aggregate principal
amount of Subordinated Notes outstanding, the maximum principal amount of
Subordinated Notes issuable, all of which were held by DeepTech.  The
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 Subordinated Notes is payable in seven equal annual
installments of approximately $8.6 million each commencing August 1, 1999. For
the six months ended December 31, 1996, Tatham Offshore paid DeepTech $3.5
million in interest on the Subordinated Notes.

During the six months ended December 31, 1996, Tatham Offshore completed its
abandonment of its West Cameron 436 property, in which it owns a 47% working
interest, at a cost of approximately $1.0 million which Tatham Offshore
anticipates it will pay in 1997.

Tatham Offshore is obligated to pay to the Partnership commodity charges, based
on the volume of oil and gas transported or processed, under certain
transportation agreements.  Also, Tatham Offshore is obligated to pay to the
Partnership $1.6 million in platform access fees annually relative to its 25%
working interest in its Phar Lap property.

The management fee agreement between Tatham Offshore and DeepTech provides for
an annual management fee which is intended to reimburse DeepTech for the
estimated costs of its operational, financial, accounting and administrative
services provided to Tatham Offshore.  Effective July 1, 1996, the management
agreement was amended to provide for an annual management fee of 24% of
DeepTech's overhead expenses.  For the six months ended December 31, 1996,
Tatham Offshore was charged $1.6 million in management fees pursuant to this
agreement.

On November 1, 1995, Tatham Offshore converted $1.7 million of its accounts
payable to an affiliate into an unsecured promissory note payable to DeepTech,
the Affiliate Note, which bears interest at 14.5% per annum, payable quarterly.
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
preferred stock pursuant to the exercise of Tatham Offshore warrants in an
amount equal to or greater than $20.0 million. In January 1997, as a result of
the exercise of Tatham Offshore warrants to purchase shares of Series C
Preferred Stock, Tatham Offshore's total proceeds from the issuance of
preferred stock exceeded $20.0 million and, as a result, Tatham Offshore made a
$0.3 million principal payment to DeepTech on January 31, 1997.

Liquidity Outlook.  During 1994 and 1995, 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 reversionary rights,
all of its then-existing working interests in its Viosca Knoll Block 817,
Garden Banks Block 72 and Garden Bank Block 117 properties (the "Assigned
Properties") to Flextrend Development for $30 million, (ii) raised additional
equity through the sale of Warrants and Series A, B and C 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.

Flextrend Development has initiated production from each of the Assigned
Properties.  As discussed above, the Viosca Knoll Block 817 (Phar Lap) is
currently producing approximately 115 MMcf of gas and 300 barrels of oil per
day.  In addition, five producing wells on Garden Banks Block 72 (Spectacular
Bid) are currently producing approximately 3,850 barrels of oil and 15 MMcf of
gas per day.  The Garden Banks Block 117 (Spend A Buck) is currently producing
approximately 1,750 barrels of oil, 3.5 MMcf of gas and 3,750 barrels of water
per day from one well.  Flextrend Development drilled a second successful well
at Garden Banks Block 117 which should be placed on production during the third
quarter of this fiscal year.





                                       24
<PAGE>   25



Effective December 10, 1996, Flextrend Development exercised its option to
permanently retain 50% of the assigned working interest in all three of the
Assigned Properties in exchange for forgiving 50% 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 with
the Partnership.  Accordingly, Tatham Offshore is entitled to receive a
reassignment of one-half interest in the Assigned Properties (37  1/2% working
interest in Viosca Knoll Block 817, 25% working interest in Garden Banks Block
72 and a 25% working interest in Garden Banks Block 117), subject to conditions
as discussed below, after Flextrend Development has received net revenues equal
to the Payout Amount. Flextrend Development remains 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.  Flextrend
Development's election to retain 50% of the assigned working interest in all
three Assigned Properties reduced the Payout Amount from $94.0 million to $50.8
million.  Subsequent to December 10, 1996, only 50% of the development and
operating costs attributable to the Assigned Properties are added to the Payout
Amount and 50% of the net revenue from the assigned working interests in the
Assigned Properties will reduce the Payout Amount.  As of December 31, 1996,
the Payout Amount was $49.6 million comprised of (a) the sum of (i) initial
acquisition and transaction costs of $32.1 million, (ii) development and
operating costs of $84.6 million, (iii) prepaid demand charges of $7.5 million
and (iv) interest of $13.1 million reduced by (b) the sum of (i) net revenue of
$44.5 million and (ii) forgiveness of $43.2 million of the Payout Amount.
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.

In September 1996, Tatham Offshore entered into a drilling arrangement (the
"Drilling Arrangement") with Sedco Forex Division of Schlumberger Technology
Corporation ("Sedco Forex"). The Drilling Arrangement includes the use of
either the semisubmersible drilling rig, the FPS Bill Shoemaker, or a
substitute rig capable of drilling in up to 1,500 feet of water.  The Drilling
Arrangement will become effective upon the mobilization of a 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 an affiliate of DeepTech and is operated by Sedco Forex
under a charter agreement.  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 prior contract commitment for work offshore Canada.  In
the event Sedco Forex mobilizes the rig to Canada, 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 one
other project, to contract to use the rig for the drilling of one well at the
then prevailing contract price.

Tatham Offshore has recently begun evaluating opportunities to acquire certain
license interests offshore eastern Canada. Emphasis is being placed on license
interests that could be acquired in exchange for (i) new securities to be
issued by Tatham Offshore, (ii) convertible notes to be issued by Tatham
Offshore, (iii) a portion of Tatham Offshore's existing Gulf of Mexico
leasehold interests, particularly its Sunday Silence field, or (iv) in
connection with Tatham Offshore's rights to utilize the FPS Bill Shoemaker.

Tatham Offshore currently intends to fund its operations with cash on hand and
cash from continuing operations. The restructuring of Tatham Offshore's
existing demand charge obligations with the Partnership, the reduction of its
overhead, the initiation of full production from the Viosca Knoll Block 817
(Phar Lap) project and improved commodity





                                       25
<PAGE>   26



prices enabled Tatham Offshore to generate approximately $0.3 million in
positive cash flow for the three months ended December 31, 1996. Tatham
Offshore does not anticipate generating significant 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 one-half of the Assigned Properties 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 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) monitoring production from 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, including Genuine Risk (Ship Shoal Block 331) and (iv)
maximizing the value of its rights under the Drilling Arrangement with Sedco
Forex regarding the FPS Bill Shoemaker.

The ability of Tatham Offshore to satisfy its capital needs beyond those funded
with the proceeds from the sale of the equity securities offered pursuant to
the rights offering will depend upon its success in implementing its business
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.  For federal leases acquired prior to
November 20, 1995, 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. 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 submitted an application relative to its Sunday Silence field
which was deemed complete by the Minerals Management Service ("MMS") effective
November 13, 1996. Under federal law, the MMS has up to 180 days to evaluate
the application once the application is deemed complete.  If the MMS requests
additional information or clarification of the submitted data during the
180-day period, the MMS may toll the review period until such information is
supplied by Tatham Offshore. Through February 13, 1997, Tatham Offshore has not
received a request for additional information.  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, successfully develop the
Sunday Silence field or initiate production therefrom on a timely basis, if at
all.

Tatham Offshore has never declared or 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.

                 At the end of each calendar month, Contractor shall prepare an
                 invoice for COMPANY documenting invoices paid, personnel

                 same to COMPANY.  CONTRACTOR shall be authorized to draw such
                 invoiced amount from the advance payment account.  COMPANY
                 shall within 30 days review such invoices and advise
                 CONTRACTOR if it is in agreement with such invoiced amounts.
                 If COMPANY and CONTRACTOR do not agree  on such invoiced
                 amounts they shall meet to resolve such differences.  At the
                 end of the workscope when all CONTRACTOR invoices and costs
                 have been invoiced (which invoicing shall be done as soon as
                 practicable) to COMPANY and COMPANY has paid all such
                 undisputed invoices, if there is an account balance remaining,
                 CONTRACTOR shall immediately return such money to COMPANY
                 including any accrued interest.  If the account balance does
                 not cover all of CONTRACTOR'S invoices to OWNER, OWNER shall
                 pay CONTRACTOR such amounts within 15 days from receipt of
                 invoice.  CONTRACTOR shall not have the right to apply or
                 withhold any portion of the deposit (including interest) with
                 respect to payments which COMPANY is disputing in good faith.

                 If advance payments are not made by Owner within 5 business
                 days from the due dates above, then CONTRACTOR shall be
                 entitled to stop work until such payments are made.  In the
                 event no advance payments are made within 15 business days
                 then CONTRACTOR shall be entitled to terminate this Agreement.
                 Notwithstanding the foregoing, if CONTRACTOR'S cumulative
                 dollar commitment amount lags the Schedule of Advance Payments
                 set forth above by two weeks or more, then COMPANY shall have
                 the right to defer additional advance payments until the
                 CONTRACTOR'S cumulative dollar commitment amount equals the
                 cumulative advance payment amount.

        B.       In consideration of CONTRACTOR providing the COMPANY with the
                 services specified in this Agreement the COMPANY shall pay to
                 CONTRACTOR a daily management fee of $2,800.

        C.       In consideration of the provision of its employees specified
                 in this Agreement COMPANY shall pay to the CONTRACTOR the
                 daily personnel rates for personnel assigned at the rates
                 defined in Appendix B.

        D.       When CONTRACTOR deems it is necessary to bring in engineering
                 support from CONTRACTOR'S affiliated companies in France to
                 assist with the engineering for the DRILLING MAKE-READY, such
                 engineers will be charged to the COMPANY at a rate of
                 $800/day/man including travel time to and from the worksite
                 and for the cost of business class airplane tickets to and
                 from their offices in Paris, France.  When such engineers are
                 performing assignments away from the rig, COMPANY shall be
                 obligated to reimburse CONTRACTOR for air fare related
                 thereto, but not for any related meals, lodging or other
                 travel expenses.  All CONTRACTOR personnel shall be housed and
                 fed on the FPS Bill Shoemaker during the term of this
                 Agreement; provided, however, that





                                       7
<PAGE>   8
                 when rig-based personnel are performing assignments off-site,
                 COMPANY shall reimburse CONTRACTOR for reasonable
                 out-of-pocket travel, lodging and meal expenses in connection
                 therewith.

        E.       At the end of each calendar month, CONTRACTOR shall submit to
                 the COMPANY its invoices, with supporting documents and
                 supporting time sheets for payment and the COMPANY shall pay
                 the invoiced amount in US Dollars not later than thirty (30)
                 days from the date of receipt of the invoice.

        F.       COMPANY shall pay CONTRACTOR interest calculated as 12% per
                 annum on interest amounts not paid within the time specified
                 in E. above.

        G.       In the event that the COMPANY is unable to pay to Contractor
                 the costs and expenses necessary to finalize the DRILLING
                 MAKE-READY, CONTRACTOR shall have the option to fund such
                 costs and expenses by making purchases of capital equipment on
                 the FPS Bill Shoemaker that is readily removable from the FPS
                 Bill Shoemaker (the "Capital Equipment").  The COMPANY may
                 purchase any of such Capital Equipment for an amount equal to
                 the amount paid by CONTRACTOR to the COMPANY for such Capital
                 Equipment plus 15% per annum through the earlier of (i) the
                 date of purchase of the Capital Equipment or (ii) the
                 termination of this Agreement.  CONTRACTOR shall retain title
                 and full rights of ownership of the Capital Equipment and the
                 Capital Equipment shall not become part of the FPS Bill
                 Shoemaker unless and until COMPANY purchases from CONTRACTOR
                 the Capital Equipment as set forth herein.

         C.      CONTRACTOR may use related parties to provide materials and
                 services in connection with this Agreement if the arrangement
                 therewith is on terms and conditions no less favorable to
                 CONTRACTOR and/or COMPANY than could be obtained in an
                 arms-length transaction with unrelated parties.

7.       PERFORMANCE BONUS

         A.      COMPANY and CONTRACTOR agree that COMPANY shall pay CONTRACTOR
                 a performance Bonus if CONTRACTOR comes in both under budget
                 and on schedule, based on the following formula:

                                  B =.20 (AFE - Actual) where:

                 B           = Bonus payable to CONTRACTOR.
                 AFE         = Agreed budget amount for total workscope per
                                Appendix C (excluding contingency).
                 Actual      = Actual cost for such total workscope.

         The performance against budget shall be determined at such time as the
         FPS Bill Shoemaker is fully tested and technically ready to commence
         operations (including acceptance testing), which date shall be no
         later than March 18, 1997, with all classification and regulatory
         approvals in-hand/in-writing even if the FPS Bill Shoemaker has not
         yet commenced a drilling contract.  Under no circumstances shall the
         Bonus be negative.

                 its employees shall continue for a period of one year from the
                 date the FPS Bill Shoemaker has been tested and is technically
                 ready to commence operations and the acceptance certificate
                 described in Article 3 has been delivered.  It shall be
                 COMPANY'S obligation, when necessary, to retrieve and
                 transport any defective work to CONTRACTOR at COMPANY'S
                 expense.

         F.      Consequential Damages

                 Notwithstanding anything to the contrary in this Agreement, a
                 party's damages resulting from a breach or violation of any
                 representation, warranty, covenant or condition contained
                 herein shall be limited to actual direct damages, and shall
                 not include any other damages, including, without limitation,
                 indirect, special, consequential, incidental or punitive
                 damages.

         G.      Gross Negligence and Related Matters

                 For purposes of Articles 8.B and 8.C, the term "Gross
                 Negligence" shall have the meaning ascribed to it in the
                 jurisprudence of the applicable jurisdiction (i.e. in Texas,
                 such term is currently interpreted as meaning, among other
                 things, conduct that is so shocking to common sensibility that
                 it would support belief that the act or omission complained of
                 was a result of conscious indifference to the right or welfare
                 of the person affected by it.  53 Tex. Jr.3d, Negligence
                 Section  55fn.).

                 The indemnities provided for above apply without regard to the
                 cause or causes thereof including, without limitation, breach
                 of contract, representation or warranty, or simple negligence,
                 whether active, passive, sole or concurrent, even if on the
                 part of the party seeking the benefit of the indemnity,
                 whether an action is founded on statute, common law, maritime
                 law or theory of strict liability.

                 Each party agrees to carry (at its expense) insurance adequate
                 to cover its indemnity obligations pursuant to this Agreement.

9.       INSURANCE

         A.      CONTRACTOR shall at its sole cost and expense procure and keep
                 in force throughout the life of this Agreement all relevant

                 including but not limited to Workmen's Compensation and
                 Employer's liability insurance or equivalent insurance
                 (Personal Accident Insurance) for covering adequately the
                 liabilities of CONTRACTOR.

         B.      COMPANY shall at its sole cost and expense procure and keep in
                 force throughout the life of this Agreement all relevant
                 personnel insurance required by local laws governing COMPANY'S
                 operations under this Agreement, including but not limited to
                 Workmen's Compensation and Employers liability insurance or
                 equivalent insurance (Personal Accident Insurance) for
                 covering adequately the liabilities of COMPANY.

         C.      COMPANY shall keep the FPS Bill Shoemaker fully insured for
                 all risks for the fair market value of the FPS Bill Shoemaker.
                 Without its obligations to fully insure its liabilities, each
                 of CONTRACTOR and COMPANY shall maintain comprehensive general
                 liability insurance (including contractual liability) in an
                 amount not less than $1,000,000. Such insurance shall name the
                 other party as an additional insured to the extent of
                 liabilities assumed by the insured party in this Agreement.
                 On request the insured party shall provide the other party
                 with a certificate from the insurers certifying that the
                 insured party has effected the above coverage, that the other
                 party is named as an additional assured to the above extent,
                 that the insured party's insurers have waived subrogation
                 against the other party thereunder and that insurer will
                 provide 30 days advance written notice to the other party.

10.      LICENSES, PERMITS, ACCOUNT REPORTING, TAXES, ETC.

         A.      Each of COMPANY and CONTRACTOR shall be responsible for all
                 matters in connection with any license, permit, accounting and
                 reporting requirement, and the like in connection with its
                 employees including making and submitting reports to the
                 proper agencies and withholding taxes, social security system,
                 workmen's compensation and Medicare premiums and submitting
                 the same to the proper authorities.  Any payments resulting
                 from the above responsibilities will be for the account of
                 COMPANY or CONTRACTOR, as applicable.

         B.      Each of COMPANY and CONTRACTOR shall be responsible for all
                 taxes levied on its personnel and/or invoices.

11.      INDEPENDENT CONTRACTOR

         It is clearly understood by both the COMPANY and the CONTRACTOR that
         CONTRACTOR in the performance of this Agreement is an independent
         CONTRACTOR and that neither it nor its employees or its subcontractors
         are employees or agents of the COMPANY.

12.      FORCE MAJEURE

         Each party to this Agreement shall be excused from complying with the
         terms and conditions of this Agreement (except for the payment of
         moneys when due), and neither party to this Agreement shall be liable
         for failure to perform under the terms of this Agreement and for so
         long as such performance is hindered or impeded by Force Majeure,
         which is defined as civil or labor disturbances, riots, wars,
         (declared or undeclared), military actions, insurrection, rebellion,
         terrorist or any Government acts, acts of any Governmental or military
         agency under actual or assumed authority, actions of elements
         (excluding adverse sea and weather conditions), floods, storms or
         other acts of nature, or any cause beyond the control of either party.

         In an event of force majeure as described above, the affected party
         within twenty-four (24) hours thereof shall take such steps as may be
         possible to overcome or mitigate the effects of such event.

13.      MISCELLANEOUS

         A.      Assignments and Subcontractors

                 Either party hereto (including a transferee of a party hereto)
                 may assign, alienate or otherwise transfer all or any portion
                 of its rights, title and interest and delegate any of its
                 obligations arising pursuant to this agreement.  Unless
                 otherwise agreed to by the parties hereto (including a
                 transferee of a party hereto), both the transferor and the
                 transferee (other than a mortgagee, pledgee or other holder of
                 a security interest) shall be jointly and severally
                 responsible and primarily liable for the full and timely
                 performance of all covenants, agreements and other
                 obligations, and the timely payment and discharge of all
                 liabilities, costs and other expenses, arising (directly or
                 indirectly) pursuant to this agreement.  Intermediary
                 transferees shall not be relieved of any obligations as a
                 result of a subsequent transfer to another individual or
                 entity.  Upon transfer of all or any portion of its rights,
                 title and interest in and to this agreement, the transferor
                 shall promptly provide the other parties hereto with a copy of
                 such transfer document.

         B.      CONTRACTOR agrees that it shall enter into written agreements
                 with each subcontractor, vendor or other party providing
                 services or materials in connection with this Agreement, and
                 each such agreement shall allow CONTRACTOR (and CONTRACTOR
                 shall) assign any warranty or similar rights to COMPANY upon
                 COMPANY'S request.  CONTRACTOR shall use commercially
                 reasonable efforts to obtain rights against such vendors,
                 contractors and other parties with respect to the quality and
                 condition of the services and materials provided.

                 Failure by either party to exercise any or all of its rights
                 hereunder, or any partial exercise thereof, shall not act as a

                 parties agree to execute such additional documents or
                 amendments as may be required in order to give effect to the
                 intent of any provision hereof which is determined to be

         F.      Parties

                 Except as otherwise provided, this Agreement is not made for
                 the benefit of third parties, and no employees, servants,

                 party to act or forbear subsequent to the termination of this
                 Agreement shall be deemed to survive the termination of this
                 Agreement.

         J.      Records Inspection Rights

                 Contractor shall, and shall cause each of its subcontractors,

                 connection with this Agreement.  To the extent necessary or
                 appropriate to verify the amounts billed to Company pursuant
                 to this Agreement and for a period of two years after the
                 termination of this Agreement, Company or its designated

         M.      Offer to Purchase

                 In the event that the COMPANY defaults on any obligation and
                 such default would result in a creditor's right to foreclosure
                 on the FPS Bill Shoemaker, the Company agrees to provide to
                 CONTRACTOR as soon as reasonably practicable, but in no event
                 later than five days after such default, a written offer to
                 sell the FPS Bill Shoemaker to CONTRACTOR at a price equal to
                 the sum of $30 million plus any costs, fees and expenses
                 associated with the DRILLING MAKE-READY and paid by the
                 COMPANY at the time of the default; including, without
                 limitation, (i) any monies advanced to CONTRACTOR for the
                 DRILLING MAKE-READY, and (ii) any monies drawn on the interim
                 construction loan to fund the DRILLING MAKE-READY.  Further,
                 the COMPANY agrees that it shall use any monies received by it
                 from CONTRACTOR for the purchase of the FPS Bill Shoemaker to
                 repay any outstanding loans to the extent such loans are
                 secured by the FPS Bill Shoemaker and CONTRACTOR is authorized
                 to pay such sums directly to any such secured creditor on
                 behalf of COMPANY pursuant to the COMPANY'S instructions.
                 Notwithstanding the foregoing, in the event COMPANY cures such
                 default prior to receiving written notice of CONTRACTOR'S
                 acceptance of the offer, such offer shall be deemed void and
                 of no further effect.

                          DEEPTECH INTERNATIONAL INC.

                      NOTE PURCHASE AND EXCHANGE AGREEMENT



                                                                January 17, 1997


BT SECURITIES CORPORATION
  One Bankers Trust Plaza
  130 Liberty Street
  New York, New York  10006


Ladies and Gentlemen:

          DeepTech International Inc., a Delaware corporation (the "Company"),
hereby confirms its agreement with you (the "Initial Purchaser"), as set forth
below.

          1. The Notes. Subject to the terms and conditions herein contained,
the Company proposes to issue and sell to the Initial Purchaser $15,350,000
aggregate principal amount of its 11% Senior Subordinated Notes due 2000 (the
"Notes"). The Notes will have the terms set forth on Exhibit A hereto and will
otherwise be in form and substance reasonably satisfactory to the Initial
Purchaser.

          The Notes will be offered and sold to the Initial Purchaser without
being registered under the Securities Act of 1933, as amended (the "Act"), in
reliance on exemptions therefrom.

          The Initial Purchaser and its direct and indirect transferees of the
Notes will be entitled to the benefits of a Registration Rights Agreement
containing the terms set forth on Exhibit A hereto and other customary terms
for private placements made pursuant to Rule 144A under the Act (the
"Registration Rights Agreement"), pursuant to which the Company will agree,
among other things, to file, under certain circumstances, a registration
statement (the "Registration Statement") with the Securities and Exchange
Commission (the "Commission") registering under the Act the Notes or exchange
notes with substantially identical terms to the Notes which will be issued in
exchange for the Notes (the "Exchange Notes"). The Exchange Notes will be
issued pursuant to an indenture (the "Indenture") which will contain terms and




                                      
<PAGE>   2



covenants substantially similar to those set forth in Article Four (except
Sections 4.10 and 4.18 thereof), Article Five and Article Six (appropriately
modified to reflect the priority of the Notes and the lack of security
therefor) in the indenture governing the Company's 12% Senior Secured Notes due
2000. The Registration Rights Agreement, the form of the Exchange Notes and the
Indenture will be in form and substance reasonably satisfactory to the Initial
Purchaser and, along with the form of the Notes, will be prepared by Cahill
Gordon & Reindel, counsel for the Initial Purchaser.

            The purchase and sale of the Notes are being made in connection
with the concurrent purchase by the Initial Purchaser from the respective
holders of (i) a $1,650,000 Promissory Note dated November 8, 1994 issued by
FPS II, Inc., as Maker, in favor of Wilrig AS, as Payee, which is now held by
Transocean AS (the "$1.65 Million Promissory Note"), (ii) a $9,350,000
Promissory Note dated November 8, 1994 issued by the Company, as Maker, in
favor of Wilrig AS, as Payee, which is now owned by Transocean AS (the "$9.35
Million Promissory Note", and together with the $1.65 Million Promissory Note,
the "Wilrig Notes"), (iii) 1,100,000 warrants issued by the Company to Wilrig
AS pursuant to the Warrant Agreement dated as of November 8, 1994 between the
Company and Wilrig AS (the "Warrants") and (iv) two $3,000,000 Promissory
Notes, each dated January 15, 1997 issued by the Company, as Maker, in favor of
Mr. Thomas P. Tatham (the "Tatham Notes").

            2. Purchase of the Notes, the Wilrig Notes, the Warrants and the
Tatham Notes. On the basis of the representations, warranties, agreements and
covenants herein contained and subject to the terms and conditions herein set
forth, (i) the Initial Purchaser agrees to sell to the Company, and the Company
agrees to purchase from the Initial Purchaser, the $1.65 Million Promissory
Note and the Warrants for an aggregate purchase price in cash of $1,650,000
plus an amount equal to accrued interest on the $1.65 Million Promissory Note
to the Closing Date and (ii) in order to refinance the indebtedness evidenced
by the $9.35 Million Promissory Note and the Tatham Notes, the Company agrees
to issue and sell to the Initial Purchaser the Notes and, in exchange therefor,
the Initial Purchaser agrees to surrender to the Company the $9.35 Million
Promissory Note and the Tatham Notes. The Initial Purchaser agrees that it will
not seek to enforce or collect any prepayment penalty due under the Tatham
Notes. One or more certificates in definitive form for the Notes that the
Initial Purchaser has agreed to purchase hereunder, and in such




                                      
                                      -2-

denomination or denominations and registered in such name or names as the
Initial Purchaser requests, shall be delivered by or on behalf of the Company
to the Initial Purchaser. Such delivery and payment shall be made at the
offices of Cahill Gordon & Reindel, 80 Pine Street, New York, New York at 10:00
A.M., New York time, on January 23, 1997, or such earlier time and place agreed
upon by the Initial Purchaser and the Company, such time and date of delivery
and payment being herein referred to as the "Closing Date."

            3.    Representations and Warranties.  The Company represents and
warrants to and agrees with the Initial Purchaser that:

            (a) Neither the Company's Annual Report on Form 10-K for the fiscal
year ended June 30, 1996 or Quarterly Report on Form 10-Q for the quarterly
period ended September 30, 1996 (collectively, the "Disclosure Documents")
filed with the Commission pursuant to the Securities Exchange Act of 1934, as
amended, and the rules and regulations promulgated thereunder (the "Exchange
Act") at the time they were filed with the Commission, as of the date hereof
and at all times subsequent hereto up to the Closing Date contained, contains
or will contain any untrue statement of a material fact or omitted, omits or
will omit to state a material fact necessary to make the statements therein, in
the light of the circumstances under which they were made, not misleading. The
Disclosure Documents, when they were filed with the Commission under the
Exchange Act, complied in all material respects with the requirements of the
Exchange Act. The Company acknowledges that the Disclosure Documents will be
used by the Initial Purchaser in connection with resales of the Notes to
subsequent purchasers thereof and consents to such use.

            (b) Each of the Company and the subsidiaries of the Company (the
"Subsidiaries") is duly incorporated, validly existing and in good standing
under the laws of its respective jurisdiction of incorporation; each of the
Company and the Subsidiaries is duly qualified to do business as a foreign
corporation in good standing in all other jurisdictions where the ownership or
leasing of its properties or the conduct of its business requires such
qualification, except where the failure to be so qualified would not,
individually or in the aggregate, reasonably be expected to have a material
adverse effect on the business, condition (financial or otherwise) or results
of operations of the Company and the Subsidiaries, taken as a whole (any such
event, a "Material Adverse Effect").

<PAGE>   4


            (c) The Company has all requisite corporate power and authority to
execute, deliver and perform each of its obligations under the Notes, the
Exchange Notes, the Registration Rights Agreement and the Indenture. The Notes
and the Exchange Notes have each been duly and validly authorized by the
Company and, when issued, sold and delivered by the Company and paid for by the
Initial Purchaser in accordance with the terms of this Agreement and the
Registration Rights Agreement, as the case may be, will constitute valid and
legally binding obligations of the Company and will be enforceable against the
Company in accordance with their terms, except that the enforcement thereof may
be subject to (i) bankruptcy, insolvency, reorganization, moratorium or other
similar laws now or hereafter in effect relating to creditors' rights and
remedies generally, and (ii) general principles of equity (regardless of
whether such enforcement may be sought in a proceeding in equity or law) and
the discretion of the court before which any proceeding therefor may be
brought.

            (d) The Indenture has been duly and validly authorized by the
Company and, when executed and delivered by the Company (assuming the due
authorization, execution and delivery by the Trustee), will constitute a valid
and legally binding agreement of the Company, enforceable against the Company
in accordance with its terms, except that the enforcement thereof may be
subject to (i) bankruptcy, insolvency, reorganization, moratorium or other
similar laws now or hereafter in effect relating to creditors' rights and
remedies generally and (ii) general principles of equity (regardless of whether
such enforcement may be sought in a proceeding in equity or law) and the
discretion of the court before which any proceeding therefor may be brought.

            (e) The Registration Rights Agreement has been duly and validly
authorized by the Company and, when executed and delivered by the Company
(assuming the due authorization, execution and delivery by the Initial
Purchaser), will constitute a valid and legally binding agreement of the
Company enforceable against the Company in accordance with its terms, except
that (A) the enforcement thereof may be subject to (i) bankruptcy, insolvency,
reorganization, moratorium or other similar laws now or hereafter in effect
relating to creditors' rights and remedies generally and (ii) general
principles of equity (regardless of whether such enforcement may be sought in a
proceeding in equity or law) and the discretion of the court before which any
proceeding therefor may be brought and (B) any rights to indemnification or
contribution thereunder may be




                                      -4-

limited by federal and state securities laws and public policy considerations.

            (f) The Company has all requisite corporate power and authority to
execute, deliver and perform its obligations under this Agreement and to
consummate the transactions contemplated hereby. This Agreement and the
consummation by the Company of the transactions contemplated hereby have been
duly and validly authorized by the Company. This Agreement has been duly
executed and delivered by the Company.

            (g) No consent, approval, authorization or order of any court or
governmental agency or body, or third party is required for the issuance and
sale by the Company of the Notes to the Initial Purchaser or the consummation
by the Company of the other transactions contemplated hereby, except such as
have been obtained and such as may be required under state securities or "Blue
Sky" laws in connection with the purchase and resale of the Notes by the
Initial Purchaser. None of the Company or the Subsidiaries is (i) in violation
of its certificate of incorporation or bylaws (or similar organizational
document), (ii) in breach or violation of any statute, judgment, decree, order,
rule or regulation applicable to any of them or any of their respective
properties or assets, except for any such breach or violation which would not,
individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect, or (iii) in breach of or default under (nor, to the best
knowledge of the Company, has any event occurred which, with notice or passage
of time or both, would constitute a default under) or in violation of any of
the terms or provisions of any indenture, mortgage, deed of trust, loan
agreement, note, lease, license, franchise agreement, permit, certificate,
contract or other agreement or instrument to which any of them is a party or to
which any of them or their respective properties or assets is subject
(collectively, "Contracts"), except for any such breach, default, violation or
event which would not, individually or in the aggregate, reasonably be expected
to have a Material Adverse Effect.

            (h) The execution, delivery and performance by the Company of this
Agreement, the Indenture and the Registration Rights Agreement and the
consummation by the Company of the transactions contemplated hereby and thereby
(including, without limitation, the issuance and sale of the Notes to the
Initial Purchaser) will not conflict with or constitute or result in a breach
of or a default under (or an event which




                                      -5-

<PAGE>   6


with notice or passage of time or both would constitute a default under) or
violation of any of (i) the terms or provisions of any Contract, except for any
such conflict, breach, violation, default or event which would not,
individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect, (ii) the certificate of incorporation or bylaws (or similar
organizational document) of the Company or any of the Subsidiaries, or (iii)
(assuming compliance with all applicable state securities or "Blue Sky" laws
and assuming the accuracy of the representations and warranties of the Initial
Purchaser in Section 7 hereof and except for any required filings with the
National Association of Securities Dealers, Inc., the filing of a registration
statement under the Act and qualification of the Indenture under the Trust
Indenture Act of 1939, as amended (the "TIA") in connection with the
Registration Rights Agreement) any statute, judgment, decree, order, rule or
regulation applicable to the Company or any of the Subsidiaries or any of their
respective properties or assets, except for any such conflict, breach or
violation which would not, individually or in the aggregate, reasonably be
expected to have a Material Adverse Effect.

            (i) The consolidated financial statements of the Company and the
Subsidiaries included in the Disclosure Documents present fairly in all
material respects the financial position, results of operations and cash flows
of the Company and the Subsidiaries at the dates and for the periods to which
they relate and have been prepared in accordance with generally accepted
accounting principles applied on a consistent basis, except as otherwise stated
therein. Price Waterhouse LLP (the "Independent Accountants") is an independent
public accounting firm within the meaning of the Act and the rules and
regulations promulgated thereunder.

            (j) There is not pending or, to the knowledge of the Company,
threatened any action, suit, proceeding, inquiry or investigation to which the
Company or any of the Subsidiaries is a party, or to which the property or
assets of the Company or any of the Subsidiaries are subject, before or brought
by any court, arbitrator or governmental agency or body which, if determined
adversely to the Company or any of the Subsidiaries, would, individually or in
the aggregate, reasonably be expected to have a Material Adverse Effect or
which seeks to restrain, enjoin, prevent the consummation of or otherwise
challenge the issuance or sale of the Notes to be sold hereunder or the
consummation of the other transactions contemplated herein.




                                      -6-

<PAGE>   7


            (k) Each of the Company and the Subsidiaries possesses all
licenses, permits, certificates, consents, orders, approvals and other
authorizations from, and has made all declarations and filings with, all
federal, state, local and other governmental authorities, all self-regulatory
organizations and all courts and other tribunals, presently required or
necessary to own or lease, as the case may be, and to operate its respective
properties and to carry on its respective businesses as now conducted
("Permits"), except where the failure to obtain such Permits would not,
individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect; each of the Company and the Subsidiaries has fulfilled and
performed all of its material obligations with respect to such Permits and no
event has occurred which allows, or after notice or lapse of time would allow,
revocation or termination thereof or results in any other material impairment
of the rights of the holder of any such Permit; and none of the Company or the
Subsidiaries has received any notice of any proceeding relating to revocation
or modification of any such Permit, except where such revocation or
modification would not, individually or in the aggregate, reasonably be
expected to have a Material Adverse Effect.

            (l) Since the date of the most recent financial statements
appearing in the Disclosure Documents, except as described therein, (i) none of
the Company or the Subsidiaries has incurred any liabilities or obligations,
direct or contingent, or entered into or agreed to enter into any transactions
or contracts (written or oral) not in the ordinary course of business which
liabilities, obligations, transactions or contracts would, individually or in
the aggregate, be material to the business, condition (financial or otherwise)
or results of operations of the Company and the Subsidiaries, taken as a whole,
(ii) none of the Company or the Subsidiaries has purchased any of its
outstanding capital stock, nor declared, paid or otherwise made any dividend or
distribution of any kind on its capital stock (other than with respect to any
of such Subsidiaries, the purchase of, or dividend or distribution on, capital
stock owned by the Company) and (iii) there has not been any material change in
the capital stock or long-term indebtedness of the Company or the Subsidiaries.

            (m) None of the Company, the Subsidiaries or any agent acting on
their behalf has taken or will take any action that might cause this Agreement
or the sale of the Notes to violate Regulation G, T, U or X of the Board of
Governors of





                                      -7-

<PAGE>   8


the Federal Reserve System, in each case as in effect, or as the same may
hereafter be in effect, on the Closing Date.

            (n) Each of the Company and the Subsidiaries has good and
marketable title to all real property and good title to all personal property
described in the Disclosure Documents as being owned by it and good and
marketable title to a leasehold estate in the real and personal property
described in the Disclosure Documents as being leased by it free and clear of
all liens, charges, encumbrances or restrictions, except as disclosed in the
Disclosure Documents and to the extent the failure to have such title or the
existence of such liens, charges, encumbrances or restrictions would not,
individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect. All leases, contracts and agreements to which the Company or
any of the Subsidiaries is a party or by which any of them is bound are valid
and enforceable against the Company or such Subsidiary, and are valid and
enforceable against the other party or parties thereto and are in full force
and effect with only such exceptions as would not, individually or in the
aggregate, reasonably be expected to have a Material Adverse Effect.

            (o) There is no significant strike, labor dispute, slowdown or work
stoppage with the employees of the Company or any of the Subsidiaries which is
pending or, to the knowledge of the Company or any of the Subsidiaries,
threatened against any of them.

            (p) No claims have been filed against the Company or any of the
Subsidiaries alleging violation of any provision of the Employee Retirement
Income Security Act of 1974, as amended ("ERISA"), except as would not,
individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect.

            (q) None of the Company or the Subsidiaries will be an "investment
company" or a company "controlled" by an "investment company," as such terms
are defined in the Investment Company Act of 1940, as amended, and the rules
and regulations thereunder.

            (r) No holder of debt securities of the Company or any Subsidiary
will be entitled to have such securities registered under the registration
statement required to be filed by the Company pursuant to the Registration
Rights Agreement.




                                      -8-

<PAGE>   9


            (s) None of the Company, the Subsidiaries or any of their
respective Affiliates (as defined in Rule 501(b) of Regulation D under the Act)
has directly, or through any agent, (i) sold, offered for sale, solicited
offers to buy or otherwise negotiated in respect of, any "security" (as defined
in the Act) which is or could be integrated with the sale of the Notes in a
manner that would require the registration under the Act of the Notes or (ii)
engaged in any form of general solicitation or general advertising (as those
terms are used in Regulation D under the Act) in connection with the offering
of the Notes or in any manner involving a public offering within the meaning of
Section 4(2) of the Act. Assuming the accuracy of the representations and
warranties of the Initial Purchaser in Section 7 hereof, it is not necessary in
connection with the offer, sale and delivery of the Notes to the Initial
Purchaser in the manner contemplated by this Agreement to register any of the
Notes under the Act.

            (t) No securities of the Company or any Subsidiary are of the same
class (within the meaning of Rule 144A under the Act) as the Notes and listed
on a national securities exchange registered under Section 6 of the Exchange
Act, or quoted in a U.S. automated inter-dealer quotation system.

            4.    Covenants of the Company.  The Company covenants and agrees
with the Initial Purchaser that:

            (a) The Company will cooperate with the Initial Purchaser in
arranging for the qualification of the Notes for offering and sale under the
securities or "Blue Sky" laws of such jurisdictions as the Initial Purchaser
may designate and will continue such qualifications in effect for as long as
may be necessary to complete the resale of the Notes; provided, however, that
in connection therewith, the Company shall not be required to qualify as a
foreign corporation or to execute a general consent to service of process in
any jurisdiction or subject itself to taxation in excess of a nominal dollar
amount in any such jurisdiction where it is not then so subject.

            (b) For the period of two years following the Closing Date, the
Company will furnish to the Initial Purchaser copies of all reports and other
communications (financial or otherwise) furnished by the Company to the trustee
for the Indenture or to the holders of the Notes or Exchange Notes and, as soon
as available, copies of any reports or financial statements furnished to or
filed by the Company with the





                                      -9-

<PAGE>   10


Commission or any national securities exchange on which any class of securities
of the Company may be listed.

            (c) Prior to the Closing Date, the Company will furnish to the
Initial Purchaser, as soon as they have been prepared, a copy of any unaudited
interim financial statements of the Company for any period subsequent to the
period covered by the most recent financial statements appearing in the
Disclosure Documents.

            (d) None of the Company or any of its Affiliates will sell, offer
for sale or solicit offers to buy or otherwise negotiate in respect of any
"security" (as defined in the Act) which could be integrated with the sale of
the Notes in a manner which would require the registration under the Act of the
Notes.

            (e) The Company will not, and will not permit any of the
Subsidiaries to, engage in any form of general solicitation or general
advertising (as those terms are used in Regulation D under the Act) in
connection with the offering of the Notes or in any manner involving a public
offering within the meaning of Section 4(2) of the Act.


            5.    Fees and Expenses.  The Company agrees to pay to the Initial
Purchaser the following non-refundable fees:

            (a)   an underwriting fee of 2.0% of the aggregate principal amount
of the Notes, payable on the Closing Date; and

            (b) reasonable legal fees and expenses (not to exceed $125,000) of
Cahill Gordon & Reindel, counsel to the Initial Purchaser, incurred by the
Initial Purchaser in connection with the transactions contemplated hereby,
whether or not the transactions are consummated.

            6.    Conditions of the Initial Purchaser's
Obligations.  The obligation of the Initial Purchaser to
purchase and pay for the Notes shall, in its sole discretion,
be subject to the satisfaction or waiver of the following
conditions on or prior to the Closing Date:

            (a) On the Closing Date, the Initial Purchaser shall have received
the opinion, dated as of the Closing Date and addressed to the Initial
Purchaser, of Akin, Gump, Strauss, Hauer & Feld, L.L.P., counsel for the
Company, in form and




                                      -10-

<PAGE>   11


substance satisfactory to counsel for the Initial Purchaser, to
the effect that:

            (i) The Company is duly incorporated, validly existing and in good
      standing under the laws of its jurisdiction of incorporation. The
      Company, based solely on good standing certificates, is qualified to do
      business as a foreign corporation in the jurisdictions listed on a
      schedule to such opinion.

           (ii) The Company has the corporate power and authority to execute,
      deliver and perform each of its obligations under the Indenture, the
      Notes and the Exchange Notes; the Indenture has been duly authorized by
      the Company and, when duly executed and delivered by the Company
      (assuming the due authorization, execution and delivery thereof by the
      Trustee), will constitute the valid and legally binding agreement of the
      Company, enforceable against the Company in accordance with its terms,
      except that the enforcement thereof may be subject to (i) bankruptcy,
      insolvency, reorganization, moratorium or other similar laws now or
      hereafter in effect relating to creditors' rights and remedies generally
      and (ii) general principles of equity (regardless of whether such
      enforcement may be sought in a proceeding in equity or law) and the
      discretion of the court before which any proceeding therefor may be
      brought.

          (iii) The Notes have each been duly authorized, executed and
      delivered by the Company and when paid for by the Initial Purchaser in
      accordance with the terms of this Agreement will constitute the valid and
      legally binding obligations of the Company and enforceable against the
      Company in accordance with their terms, except that the enforcement
      thereof may be subject to (i) bankruptcy, insolvency, reorganization,
      moratorium or other similar laws now or hereafter in effect relating to
      creditors' rights and remedies generally and (ii) general principles of
      equity (regardless of whether such enforcement may be sought in a
      proceeding in equity or law) and the discretion of the court before which
      any proceeding therefor may be brought.

           (iv) The Exchange Notes have been duly authorized by the Company,
      and when they are duly executed and delivered by the Company in
      accordance with the terms of the Registration Rights Agreement and the
      Indenture (assuming

<PAGE>   12


      the due authorization, execution and delivery of the Indenture by the
      Trustee and due authentication and delivery of the Exchange Notes by the
      Trustee in accordance with the Indenture), will constitute the valid and
      legally binding obligations of the Company, entitled to the benefits of
      the Indenture, and enforceable against the Company in accordance with
      their terms, except that the enforcement thereof may be subject to (i)
      bankruptcy, insolvency, reorganization, moratorium or other similar laws
      now or hereafter in effect relating to creditors' rights and remedies
      generally and (ii) general principles of equity (regardless of whether
      such enforcement may be sought in a proceeding in equity or law) and the
      discretion of the court before which any proceeding therefor may be
      brought.

            (v) The Company has the corporate power and authority to execute,
      deliver and perform its obligations under the Registration Rights
      Agreement; the Registration Rights Agreement has been duly authorized,
      executed and delivered by the Company and (assuming due authorization,
      execution and delivery thereof by the Initial Purchaser) constitutes the
      valid and legally binding agreement of the Company, enforceable against
      the Company in accordance with its terms, except that (A) the enforcement
      thereof may be subject to (i) bankruptcy, insolvency, reorganization,
      moratorium or other similar laws now or hereafter in effect relating to
      creditors' rights and remedies generally and (ii) general principles of
      equity (regardless of whether such enforcement may be sought in a
      proceeding in equity or law) and the discretion of the court before which
      any proceeding therefor may be brought and (B) any rights to
      indemnification or contribution thereunder may be limited by federal and
      state securities laws and public policy considerations.

           (vi) The Company has the corporate power and authority to execute,
      deliver and perform its obligations under this Agreement and to
      consummate the transactions contemplated hereby; this Agreement and the
      consummation by the Company of the transactions contemplated hereby have
      been duly and validly authorized, executed and delivered by the Company.

          (vii) The execution, delivery and performance of this Agreement, the
      Notes, the Indenture, the Registration Rights Agreement and the
      consummation of the transactions




                                      -12-

      contemplated hereby and thereby (including the transfer of ownership to
      the Initial Purchaser of the Wilrig Notes, the Warrants and the Tatham
      Notes and the redemption of the Wilrig Notes and the Tatham Notes on the
      Closing Date) will not conflict with or constitute or result in a breach
      or a default under (or an event which with notice or passage of time or
      both would constitute a default under) or violation of any of (i) the
      terms or provisions of any Contract known to such counsel, except for any
      such conflict, breach, violation, default or event which would not,
      individually or in the aggregate, reasonably be expected to have a
      Material Adverse Effect, (ii) the certificate of incorporation or bylaws
      (or similar organizational document) of the Company or any of the
      Subsidiaries, or (iii) (assuming compliance with all applicable state
      securities or "Blue Sky" laws and assuming the accuracy of the
      representations and warranties of the Initial Purchaser in Section 7
      hereof) any statute, judgment, decree, order, rule or regulation known to
      such counsel to be applicable to the Company or any of the Subsidiaries
      or any of their respective properties or assets, except for any such
      conflict, breach or violation which would not, individually or in the
      aggregate, reasonably be expected to have a Material Adverse Effect.

         (viii) No consent, approval, authorization or order of any
      governmental authority is required for the issuance and sale by the
      Company of the Notes to the Initial Purchaser or the consummation by the
      Company of the other transactions contemplated hereby, except such as may
      be required under Blue Sky laws, as to which such counsel need express no
      opinion, and those which have previously been obtained and except for the
      filing of a registration statement under the Act and qualification of the
      Indenture under the TIA in connection with the Registration Rights
      Agreement.

           (ix) None of the Company or the Subsidiaries is, or immediately
      after the sale of the Notes to be sold hereunder will be subject to
      registration as an "investment company" under the Investment Company Act
      of 1940, as amended.

            (x) Prior to the issuance of the Exchange Notes, the offer,
      issuance, sale and delivery of the Notes in the manner contemplated
      herein do not require registration




                                      -13-

<PAGE>   14


      under the Act or qualification of the Indenture under the TIA.

            (b) The representations and warranties of the Company contained in
this Agreement shall be true and correct on and as of the date hereof and on
and as of the Closing Date as if made on and as of the Closing Date; the
Company shall have performed all covenants and agreements and satisfied all
conditions on their part to be performed or satisfied hereunder at or prior to
the Closing Date; and, subsequent to the date of the most recent financial
statements in the Disclosure Documents, there shall have been no event or
development, and no information shall have become known, that, individually or
in the aggregate, has or would be reasonably likely to have a Material Adverse
Effect.

            (c) The sale of the Notes hereunder shall not be enjoined
(temporarily or permanently) on the Closing Date.

            (d) The Initial Purchaser shall have received a certificate of the
Company, dated the Closing Date, signed on behalf of the Company by its
Chairman of the Board, President or any Senior Vice President and the Chief
Financial Officer, to the effect that:

            (i) The representations and warranties of the Company contained in
      this Agreement are true and correct on and as of the date hereof and on
      and as of the Closing Date, and the Company has performed all covenants
      and agreements and satisfied all conditions on its part to be performed
      or satisfied hereunder at or prior to the Closing Date;

           (ii) At the Closing Date, since the date hereof or since the date of
      the most recent financial statements in the Disclosure Documents, no
      event or development has occurred, and no information has become known,
      that, individually or in the aggregate, has or would be reasonably likely
      to have a Material Adverse Effect; and

            (e) On or prior to the Closing Date, the Initial Purchaser shall
have purchased the Wilrig Notes, the Warrants and the Tatham Notes, and
received physical delivery thereof; provided, that this condition shall be
deemed waived in the event that such transactions are not consummated solely by
reason of a default by BTSC of its obligations under its agreements with
Transocean AS and Mr. Tatham relating thereto.




                                      -14-

<PAGE>   15


            (f) On the Closing Date, the Initial Purchaser shall have received
the Registration Rights Agreement (together with the form of Indenture and
Exchange Note attached thereto as an Exhibit) executed by the Company and such
agreement shall be in full force and effect at all times from and after the
Closing Date.

            (g) On the Closing Date and concurrently with the issuance of the
Notes, the Company shall have purchased the Wilrig Notes, the Warrants and the
Tatham Notes in accordance with Section 2 hereof.

            All such documents, opinions, certificates, letters, schedules or
instruments delivered pursuant to this Agreement will comply with the
provisions hereof only if they are reasonably satisfactory in all material
respects to the Initial Purchaser and counsel for the Initial Purchaser.

            7. Offering of Notes; Restrictions on Transfer. The Initial
Purchaser hereby represent and warrants that it has entered into an agreement
with Transocean AS to purchase the Wilrig Notes and the Warrants and has
furnished a true, correct and complete copy of such agreement to the Company.
The Initial Purchaser hereby covenants and agrees that it will fully perform
its obligations under such agreement and that it will not amend, modify,
supplement, or terminate, or consent to or permit any such amendment,
modification, supplement or termination of, such agreement, without the prior
written consent of the Company. The Initial Purchaser hereby represents and
warrants that it is a QIB, with such knowledge and experience in financial and
business matters as are necessary in order to evaluate the merits and risks of
an investment in the Notes. The Initial Purchaser agrees with the Company that
(i) it has not and will not solicit offers for, or offer or sell, the Notes by
any form of general solicitation or general advertising (as those terms are
used in Regulation D under the Act) or in any manner involving a public
offering within the meaning of Section 4(2) of the Act; and (ii) it has
solicited, and will solicit, offers for the Notes only from, and will offer the
Notes only to (A) in the case of offers inside the United States, (x) persons
whom the Initial Purchaser reasonably believes to be QIBs or, if any such
person is buying for one or more institutional accounts for which such person
is acting as fiduciary or agent, only when such person has represented to the
Initial Purchaser that each such account is a QIB, to whom notice has been
given that such sale or delivery is being made in reliance on Rule 144A, and,
in each




                                      -15-

<PAGE>   16


case, in transactions under Rule 144A or (y) a limited number of other
institutional investors reasonably believed by the Initial Purchaser to be
Accredited Investors and (B) in the case of offers outside the United States in
a transaction meeting the requirements of Rule 904 under the Act, to persons
other than U.S. persons ("foreign purchasers," which term shall include dealers
or other professional fiduciaries in the United States acting on a
discretionary basis for foreign beneficial owners (other than an estate or
trust)).

            The Initial Purchaser understands that the Company and, for
purposes of the opinion to be delivered to the Initial Purchaser pursuant to
Section 6 hereof, counsel to the Company will rely upon the accuracy and truth
of the foregoing representations and hereby consents to such reliance.

            8. Indemnification and Contribution. (a) The Company agrees to
indemnify and hold harmless the Initial Purchaser, its affiliates and their
respective directors, officers, partners, agents, employees, representatives
and control persons (collectively, the "Indemnified Persons") from and against
any losses, claims, damages or liabilities to which such Indemnified Person may
become subject under the Act, the Exchange Act or otherwise, insofar as any
such losses, claims, damages or liabilities (or actions in respect thereof)
arise out of or are based upon any untrue statement or alleged untrue statement
of any material fact contained in any Disclosure Document or the omission or
alleged omission to state in any Disclosure Document a material fact required
to be stated therein or necessary to make the statements therein not
misleading, or any of the transactions contemplated hereby and will reimburse,
as incurred, the Indemnified Person for any legal or other expenses incurred by
Indemnified Person in connection with investigating, defending against or
appearing as a third-party witness in connection with any such loss, claim,
damage, liability or action; provided, that this indemnity shall not be
available for any loss, claim, damages, liability or action to the extent they
are determined by a court of competent jurisdiction in a final and
nonappealable judgment to have resulted from the intentional misconduct or
gross negligence of the Initial Purchaser. This indemnity agreement will be in
addition to any liability that the Company may otherwise have to the
indemnified parties. The Company shall not be liable under this Section 8 for
any settlement of any claim or action effected without its prior written
consent, which shall not be unreasonably withheld.





                                      -16-

<PAGE>   17


            (b) Promptly after receipt by an indemnified party under this
Section 9 of notice of the commencement of any action for which such
Indemnified Person is entitled to indemnification under this Section 8, such
Indemnified Person will, if a claim in respect thereof is to be made against
the Company under this Section 8, notify the Company of the commencement
thereof in writing; but the omission to so notify the Company (i) will not
relieve it from any liability under paragraph (a) above unless and to the
extent such failure results in the forfeiture by the Company of substantial
rights and defenses and (ii) will not, in any event, relieve the Company from
any obligations to any Indemnified Person other than the indemnification
obligation provided in paragraphs (a) above. In case any such action is brought
against any Indemnified Person, and it notifies the Company of the commencement
thereof, the Company will be entitled to participate therein and, to the extent
that it may wish, to assume the defense thereof, with counsel reasonably
satisfactory to such Indemnified Person; provided, however, that if (i) the use
of counsel chosen by the Company to represent the Indemnified Person would
present such counsel with a conflict of interest, (ii) the defendants in any
such action include both the Indemnified Person and the Company and the
Indemnified Person shall have been advised by counsel that there may be one or
more legal defenses available to it and/or other Indemnified Persons that are
different from or additional to those available to the Company, or (iii) the
Company shall not have employed counsel reasonably satisfactory to the
Indemnified Person to represent the Indemnified Person within a reasonable time
after receipt by the Company of notice of the institution of such action, then,
in each such case, the Company shall not have the right to direct the defense
of such action on behalf of such Indemnified Person and such Indemnified Person
shall have the right to select separate counsel to defend such action on behalf
of such Indemnified Person. After notice from the Company to such Indemnified
Person of its election so to assume the defense thereof and approval by such
Indemnified Person of counsel appointed to defend such action, the Company will
not be liable to such Indemnified Person under this Section 8 for any legal or
other expenses, other than reasonable costs of investigation, subsequently
incurred by such Indemnified Person in connection with the defense thereof,
unless (i) the Indemnified Person shall have employed separate counsel in
accordance with the proviso to the immediately preceding sentence (it being
understood, however, that in connection with such action the Company shall not
be liable for the expenses of more than one




                                      -17-

<PAGE>   18


separate counsel (in addition to local counsel) in any one action or separate
but substantially similar actions in the same jurisdiction arising out of the
same general allegations or circumstances, designated by the Indemnified
Person), as the case may be, who are parties to such action or actions) or (ii)
the Company has authorized in writing the employment of counsel for the
Indemnified Person at the expense of the Company.

            (c) In circumstances in which the indemnity agreement provided for
in the preceding paragraphs of this Section 9 is unavailable to, or
insufficient to hold harmless, an Indemnified Person in respect of any losses,
claims, damages or liabilities (or actions in respect thereof), the Company, in
order to provide for just and equitable contribution, shall contribute to the
amount paid or payable by such Indemnified Person as a result of such losses,
claims, damages or liabilities (or actions in respect thereof) in such
proportion as is appropriate to reflect (i) the relative benefits received by
the Company on the one hand from the transactions contemplated hereby and the
Indemnified Person on the other from the offering of the Notes or (ii) if the
allocation provided by the foregoing clause (i) is not permitted by applicable
law, not only such relative benefits but also the relative fault of the Company
on the one hand and the Indemnified Person on the other in connection with the
statements or omissions or alleged statements or omissions or other actions
that resulted in such losses, claims, damages or liabilities (or actions in
respect thereof). The relative benefits received by the Company on the one hand
and the Initial Purchaser on the other shall be deemed to be in the same
proportion as the aggregate principal amount of the Notes bear to the total
commissions received hereunder by the Initial Purchaser. The relative fault of
the parties shall be determined by reference to, among other things, whether
the untrue or alleged untrue statement of a material fact or the omission or
alleged omission to state a material fact relates to information supplied by
the Company, the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission or alleged
statement or omission, and any other equitable considerations appropriate in
the circumstances. The Company and the Initial Purchaser agree that it would
not be equitable if the amount of such contribution were determined by pro rata
or per capita allocation or by any other method of allocation that does not
take into account the equitable considerations referred to in the first
sentence of this paragraph (d). Notwithstanding any other provision of this
paragraph (d), the Initial Purchaser




                                      -18-

<PAGE>   19


shall not be obligated to make contributions hereunder that in the aggregate
exceed the total commissions received by the Initial Purchaser under this
Agreement, less the aggregate amount of any damages that the Initial Purchaser
has otherwise been required to pay by reason of the untrue or alleged untrue
statements or the omissions or alleged omissions to state a material fact, and
no person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. For purposes of this paragraph
(d), each person, if any, who controls the Initial Purchaser within the meaning
of Section 15 of the Act or Section 20 of the Exchange Act shall have the same
rights to contribution as the Initial Purchaser.

            9. Survival Clause. The respective representations, warranties,
agreements, covenants, indemnities and other statements of the Company, its
officers and the Initial Purchaser set forth in this Agreement or made by or on
behalf of them pursuant to this Agreement shall remain in full force and
effect, regardless of (i) any investigation made by or on behalf of the
Company, any of its officers or directors, the Initial Purchaser or any
controlling person referred to in Section 8 hereof and (ii) delivery of and
payment for the Notes. The respective agreements, covenants, indemnities and
other statements set forth in Sections 5, 8 and 13 hereof shall remain in full
force and effect, regardless of any termination or cancellation of this
Agreement.

            10. Termination. (a) This Agreement may be terminated by the
Initial Purchaser upon written notice to the Company given prior to the Closing
Date in the event that the Company shall have failed, refused or been unable to
perform all obligations and satisfy all conditions on its part to be performed
or satisfied hereunder at or prior thereto or, if at or prior to the Closing
Date and since the date of the most recent financial statement in the
Disclosure Documents there shall have been any event or development that,
individually or in the aggregate, has or could reasonably be expected to have a
Material Adverse Effect.

            (b) Termination of this Agreement pursuant to this Section 10 shall
be without liability of any party to any other party.

            11.   Notices.  All communications hereunder shall be in writing
and, if sent to the Initial Purchaser, shall be




                                      -19-

            All such notices and communications shall be deemed to have been
duly given: when delivered by hand, if personally delivered; five business days
after being deposited in the mail, postage prepaid, if mailed; and one business
day after being timely delivered to a next-day air courier.

            12. Successors. This Agreement shall inure to the benefit of and be
binding upon the Initial Purchaser, the Company and their respective successors
and legal representatives, and nothing expressed or mentioned in this Agreement
is intended or shall be construed to give any other person any legal or
equitable right, remedy or claim under or in respect of this Agreement, or any
provisions herein contained; this Agreement and all conditions and provisions
hereof being intended to be and being for the sole and exclusive benefit of
such persons and for the benefit of no other person except that the indemnities
of the Company contained in Section 9 of this Agreement shall also be for the
benefit of any person or persons who control the Initial Purchaser within the
meaning of Section 15 of the Act or Section 20 of the Exchange Act and. No
purchaser of Notes from the Initial Purchaser will be deemed a successor
because of such purchase.

            13. APPLICABLE LAW. THE VALIDITY AND INTERPRETATION OF THIS
AGREEMENT, AND THE TERMS AND CONDITIONS SET FORTH HEREIN SHALL BE GOVERNED BY
AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK APPLICABLE
TO CONTRACTS MADE AND TO BE PERFORMED WHOLLY THEREIN, WITHOUT GIVING EFFECT TO
ANY PROVISIONS THEREOF RELATING TO CONFLICTS OF LAW.

            14.   Counterparts.  This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.





            If the foregoing correctly sets forth our understanding, please
indicate your acceptance thereof in the space provided below for that purpose,
whereupon this letter shall constitute a binding agreement between the Company
and the Initial Purchaser.

                                           Very truly yours,

                                           DEEPTECH INTERNATIONAL INC.

                                    "Registration Rights Agreement") between
                                    the Company and the Initial Purchaser, (i)

                                    of the Company with substantially identical
                                    terms to the Notes (the "Exchange Notes")
                                    within 30 days after receipt of demand
                                    (which demand shall not be made prior to
                                    the 30-day period following the date of the
                                    Note Purchase and Exchange Agreement) from
                                    holders of at least 75% of the principal
                                    amount of the Notes and (ii) to use its
                                    best efforts to cause such registration
                                    statement to become effective under the
                                    Securities Act within 90 days after such
                                    issue date.  In the event that applicable
                                    interpretations of the staff of the
                                    Commission do not permit the Company to
                                    effect the Exchange Offer, or if for any
                                    other reason the Exchange Offer is not
                                    consummated, the Company will use its best
                                    efforts to cause to become effective a
                                    shelf registration statement with respect
                                    to the resale of the Exchange Notes and to
                                    keep such shelf registration statement
                                    effective until the earlier of three years
                                    after the date of original issue of the
                                    Exchange Notes and such time as all of the
                                    Exchange Notes have been sold thereunder. 
                                    If the Company is in default under the
                                    Registration Rights Agreement, then the
                                    Company shall promptly notify the holders
                                    of the Notes of such noncompliance and
                                    shall commence an offer to repurchase all
                                    outstanding Notes at a price equal to 100%
                                    of the principal amount thereof plus
                                    accrued interest to the repurchase date.
                                    Such offer shall remain open for not less
                                    than 45 days after receipt thereof by the
                                    holders. All expenses of registration shall
                                    be for the Company's account, except for
                                    underwriting discounts and commissions, if
                                    any.

"Construction Fund Collateral Account") over which the Collateral and
Documentation Agent shall have sole dominion and control and from which the
Borrower shall have no right of withdrawal and shall also establish a
subaccount (the "Restricted Funds Collateral Subaccount") of the Construction
Fund Collateral Account.  As provided in paragraph (a) above, on the Closing
Date $24,294,782.64 of the proceeds of the Loans will be deposited in the
Construction Fund Collateral Account and $7,961,027.74 of the proceeds of the

undertaking commitments to obtain goods and services (and providing reasonable
detail of such goods and services) in accordance with the Shoemaker Upgrade

Documentation Agent to release funds from the Construction Fund Collateral
Account (but, prior to the Second Closing Date, not from the Restricted Funds

Collateral and Documentation Agent will release such funds and transfer the
same as directed by the Charterer for safekeeping, pending payment of invoices
for such goods and services; provided, however, that (i) if the Amoco Drilling
Contract Date has not occurred by November 30, 1996, then all sums then on
deposit in the Restricted Funds Collateral Subaccount shall be applied to the
mandatory prepayment of the Loans for application in accordance with the
provisions of subsection 2.5(d), (ii) if the Amoco Drilling Contract Date has
occurred by November 30, 1996, then on the Funds Transfer Date, (x) so much of
the sums then on deposit in the Restricted Funds Collateral Subaccount as may,
in the view of the Borrower and the Charterer, be necessary to collateralize

Drilling Contract) in accordance with the Shoemaker Upgrade Agreement as then
in effect shall be transferred from the Restricted

Collateral Account and made available in accordance with this subsection
2.2(b), (y) the first $2,500,000 (or such lesser amount as may then be on

deposit in the Restricted Funds Collateral Subaccount shall be released to the
Borrower and may be used by the Borrower to finance capital expenditures in
respect of any of the Rigs, without regard to any limit set forth in section
6.8 of this Agreement and (z) the remainder of the funds in the Restricted
Funds Collateral Subaccount shall remain in such account until such time as the
upgrade contemplated by the Shoemaker Upgrade Agreement shall have been
completed and thereafter released to the Borrower in the same manner
contemplated by clause (y) above; provided that if pursuant to the procedure
described in clause (x) above additional funds shall be required to complete
the make ready of the Shoemaker, such funds shall be transferred to the general
portion of the Construction Fund Collateral Account out of the Restricted Funds
Collateral Subaccount.

a promissory note of the Borrower, substantially in the form of Exhibit A (the
"Note"), with appropriate insertions therein as to payee, date and principal
amount, payable to the order of such Lender and in a principal amount equal to
the Loan of such Lender.  Each Lender is hereby authorized to record the date
and amount of each payment or prepayment of principal of its Loan on the
schedule annexed to and constituting a part of its Note, and any such
recordation shall constitute prima facie evidence of the accuracy of the
information so recorded.  The Note shall (a) be dated the Closing Date, (b) be
stated to mature in 8 consecutive quarterly installments, payable on the last

aggregate amount for all the Lenders of $63,250,000 and (c) provide for the
payment of interest in accordance with subsection 2.6.

from time to time prepay the Loans, in whole or in part, without premium or
penalty, upon at least four Business Days' irrevocable notice to the
Administrative Agent, specifying the date and amount of prepayment.  Upon
receipt of any such notice the Administrative Agent shall promptly notify each
Lender thereof.  If any such notice is given, the amount specified in such
notice shall be due and payable on the date specified therein, together with
accrued interest to such date on the amount prepaid.  Subject to subsection
2.5(d), partial prepayments of the Loans shall be applied to the installments
of principal thereof in the inverse order of their scheduled maturities.
Amounts prepaid on account of the Loans may not be reborrowed.  Partial
prepayments shall be in an aggregate principal amount of $1,000,000 or a whole
multiple thereof.

                 2.5  Mandatory Prepayments.  (a)  If, subsequent to the

Capital Stock or incur any Indebtedness other than pursuant to a Permitted
Issuance, 100% of the Net Proceeds thereof shall be applied on each date of
receipt of such proceeds toward the prepayment of the Loans as set forth in
subsection 2.5(d).

                                                                              19




                 (b)  If, subsequent to the Closing Date, the Borrower or any
of its Restricted Subsidiaries shall receive Net Proceeds from any Asset Sale,

toward the prepayment of the Loans as set forth in subsection 2.5(d).

                 (c)  If for any fiscal quarter, commencing with the fiscal
quarter following the fiscal quarter in which the Closing Date occurs, there

Flow shall be applied toward prepayment of the Loans as set forth in subsection
2.5(d).  Each such prepayment shall be made on or before the forty-fifth day
following the last day of such fiscal quarter.

                 (d)  Subject to the third succeeding sentence, prepayments
made pursuant to this subsection 2.5 shall be applied by the Borrower to the
prepayment of the Loans pro rata according to the outstanding principal amounts
thereof held by the respective Lenders.  Prepayments of the Loans pursuant to
this subsection 2.5 shall be applied to the remaining installments of each Loan
in the inverse order of their scheduled maturities.  Amounts prepaid on account
of the Loans may not be reborrowed.  With respect to any prepayment pursuant to
subsection 2.4 or this subsection 2.5 (other than a prepayment in full of the
Loans), at any time prior to the date of such prepayment, any holder of Loans
may notify the Borrower and the Administrative Agent that such holder of Loans
elects not to have such prepayment applied to such Loans pursuant to this
subsection 2.5(d).  Any such notice given by any such holder of Loans shall
become effective on the date three Business Days after the date received by the
Borrower and the Administrative Agent and shall remain in effect until the date
three Business Days after the date on which the Borrower and the Administrative
Agent receive a notice of revocation from such holder; provided, however, in
the case of a mandatory prepayment pursuant to this subsection 2.5, a holder of
Loans which elects not to have such prepayment applied to such Loans may notify
the Borrower and the Administrative Agent of such election and in such event
shall immediately return any moneys it has received on account of such
mandatory prepayment to the Administrative Agent, which moneys (and any moneys
which such holder would be entitled to but had not yet received on account of
such mandatory prepayment had it not made such an election) shall be applied in
accordance with the immediately succeeding sentence.  If any such holder of a
Loan shall have so elected not to have prepayments applied to such Loan, the
amount of such prepayment which would have been applied to such Loan shall be
instead applied to the Loans held by any holder which has not made an election
pursuant to this subsection 2.5(d), pro rata in accordance with the principal
amounts held by such holders.

                 (e)  The Borrower shall give the Administrative Agent (which
shall promptly notify each Lender) at least one Business Day's notice of each
prepayment pursuant to this subsection 2.5 setting forth the date and amount
thereof.

                 2.6  Interest Rates and Payment Dates.  (a)  Each Loan shall
bear interest at a rate per annum equal to the Base Rate plus 3% per annum.
<PAGE>   24
                                                                              20




                 (b)  If all or a portion of (i) any principal of any Loan,
(ii) any interest payable thereon, (iii) any other amount payable hereunder or
in connection herewith shall not be paid when due (whether at the stated
maturity, by acceleration or otherwise), the principal of the Loans and any
such overdue interest or other amount shall bear interest at a rate per annum
which is the rate described in paragraph (a) of this subsection plus 2%, in
each case from the date of such non-payment until such overdue principal,
interest, commitment fee or other amount is paid in full (as well after as
before judgment).

                 (c)  Interest shall be payable in arrears on each Interest
Payment Date, provided that interest accruing pursuant to paragraph (b) of this
subsection shall be payable from time to time on demand.

                 2.7  Computation of Interest.  (a) Whenever it is calculated
on the basis of the Prime Rate, interest shall be calculated on the basis of a
365- (or 366-, as the case may be) day year for the actual days elapsed; and,
otherwise, interest shall be calculated on the basis of a 360-day year for the
actual days elapsed.  Any change in the interest rate on a Loan resulting from
a change in the Base Rate, the C/D Assessment Rate or the C/D Reserve
Percentage shall become effective as of the opening of business on the day on
which such change becomes effective.  The Administrative Agent shall as soon as
practicable notify the Borrower and the Lenders of the effective date and the
amount of each such change in interest rate.

                 (b)  Each determination of an interest rate by the
Administrative Agent pursuant to any provision of this Agreement shall be
conclusive and binding on the Borrower and the Lenders in the absence of
manifest error.

                 2.8  Pro Rata Treatment and Payments.  (a)  Except as provided
in subsection 2.5(d), each payment (including each prepayment) by the Borrower
on account of principal of and interest on the Loans shall be made pro rata
according to the respective outstanding principal amounts of the Loans then
held by the Lenders.  All payments (including prepayments) to be made by the
Borrower hereunder, whether on account of principal, interest, fees or
otherwise, shall be made without set off or counterclaim and shall be made
prior to 12:00 Noon, New York City time, on the due date thereof to the
Administrative Agent, for the account of the Lenders, at the Administrative
Agent's office specified in subsection 9.2, in Dollars and in immediately
available funds.  The Administrative Agent shall distribute such payments to
the Lenders promptly upon receipt in like funds as received.  If any payment
hereunder becomes due and payable on a day other than a Business Day, such
payment shall be extended to the next succeeding Business Day, and, with
respect to payments of principal, interest thereon shall be payable at the then
applicable rate during such extension.

                 (b)  Unless the Administrative Agent shall have been notified
in writing by any Lender prior to the Closing Date that such Lender will not
make the amount that would constitute its Commitment Percentage of the Loans
available to the Administrative Agent, the Administrative Agent may assume that
such Lender is making such amount available to the Administrative Agent, and
the Administrative Agent may, in reliance upon such assumption,
<PAGE>   25
                                                                              21



make available to the Borrower a corresponding amount.  If such amount is not
made available to the Administrative Agent by the required time on the Closing
Date therefor, such Lender shall pay to the Administrative Agent, on demand,
such amount with interest thereon at a rate equal to the daily average Federal
Funds Effective Rate for the period until such Lender makes such amount
immediately available to the Administrative Agent.  A certificate of the
Administrative Agent submitted to any Lender with respect to any amounts owing
under this subsection shall be conclusive in the absence of manifest error.  If
such Lender's Commitment Percentage of the borrowing is not made available to
the Administrative Agent by such Lender within three Business Days of the
Closing Date, the Administrative Agent shall also be entitled to recover such
amount with interest thereon at the rate per annum applicable to Loans
hereunder, on demand, from the Borrower.

                 2.9  Taxes.  (a)  All payments made by the Borrower under this
Agreement and any Notes shall be made free and clear of, and without deduction
or withholding for or on account of, any present or future income, stamp or
other taxes, levies, imposts, duties, charges, fees, deductions or
withholdings, now or hereafter imposed, levied, collected, withheld or assessed
by any Governmental Authority, excluding net income taxes and franchise taxes
(imposed in lieu of net income taxes) imposed on any Agent or any Lender as a
result of a present or former connection between any Agent or such Lender and
the jurisdiction of the Governmental Authority imposing such tax or any
political subdivision or taxing authority thereof or therein (other than any
such connection arising solely from such Agent or such Lender having executed,
delivered or performed its obligations or received a payment under, or
enforced, this Agreement or any Note).  If any such non-excluded taxes, levies,
imposts, duties, charges, fees deductions or withholdings ("Non-Excluded
Taxes") are required to be withheld from any amounts payable to any Agent or
any Lender hereunder or under any Note, the amounts so payable to such Agent or
such Lender shall be increased to the extent necessary to yield to such Agent
or such Lender (after payment of all Non-Excluded Taxes) interest or any such
other amounts payable hereunder at the rates or in the amounts specified in
this Agreement, provided, however, that the Borrower shall not be required to
increase any such amounts payable to any Lender that is not organized under the
laws of the United States of America or a state thereof if such Lender fails to
comply with the requirements of paragraph (b) of this subsection.  Whenever any
Non-Excluded Taxes are payable by the Borrower, as promptly as possible
thereafter the Borrower shall send to the relevant Agent for its own account or
for the account of such Lender, as the case may be, a certified copy of an
original official receipt received by the Borrower showing payment thereof.  If
the Borrower fails to pay any Non-Excluded Taxes when due to the appropriate
taxing authority or fails to remit to the relevant Agent the required receipts
or other required documentary evidence, the Borrower shall indemnify the Agents
and the Lenders for any incremental taxes, interest or penalties that may
become payable by any Agent or any Lender as a result of any such failure.  The
agreements in this subsection shall survive the termination of this Agreement
and the payment of the Loans and all other amounts payable hereunder.

                 (b)  Each Lender, Assignee and Participant that is not a
citizen or resident of the United States of America, a corporation, partnership
or other entity created or organized in or under the laws of the United States
of America, or any estate or trust that is subject to
<PAGE>   26
                                                                              22



U.S. federal income taxation regardless of the source of its income (a
"Non-U.S. Lender") shall deliver to the Borrower and the Administrative Agent,
and if applicable, the assigning Lender (or, in the case of a Participant, to
the Lender from which the related participation shall have been purchased) on
or before the date on which it becomes a party to this Agreement (or, in the
case of a Participant, on or before the date on which such Participant
purchases the related participation) either:

                 (A)      (x) two duly completed and signed copies of either
         Internal Revenue Service Form 1001 (relating to such Non-U.S. Lender
         and entitling it to a complete exemption from withholding of U.S.
         Taxes on all amounts to be received by such Non-U.S. Lender pursuant
         to this Agreement and the other Loan Documents) or Form 4224 (relating
         to all amounts to be received by such Non-U.S. Lender pursuant to this
         Agreement and the other Loan Documents), or successor and related
         applicable forms, as the case may be, and (y) two duly completed and
         signed copies of Internal Revenue Service Form W-8 or W-9, or
         successor and related applicable forms, as the case may be; or

                 (B)      in the case of a Non-U.S. Lender that is not a "bank"
         within the meaning of Section 881(c)(3)(A) of the Code and that does
         not comply with the requirements of clause (A) hereof, (x) a statement
         in the form of Exhibit H (or such other form of statement as shall be
         reasonably requested by the Borrower from time to time) to the effect
         that such Non-U.S. Lender is eligible for a complete exemption from
         withholding of U.S. Taxes under Code Section 871(h) or 881(c), and (y)
         two duly completed and signed copies of Internal Revenue Service Form
         W-8 or successor and related applicable form (it being understood and
         agreed that no Participant and, without the prior written consent of
         the Borrower described in clause (B) of the proviso to the first
         sentence of subsection 9.6(c), no Assignee shall be entitled to
         deliver any forms or statements pursuant to this clause (B), but
         rather shall be required to deliver forms pursuant to clause (A) of
         this subsection 2.9(b)).

Each Non-U.S. Lender that delivers a statement in the form of Exhibit H (or
such other form of statement as shall have been requested by the Borrower)
agrees that it shall hold only Qualified Non-U.S. Lender Notes and that it
shall be the sole beneficial and record owner of all Qualified Non-U.S. Lender
Notes held by it.  Further, each Non-U.S. Lender agrees (i) to deliver to the
Borrower and the Administrative Agent, and if applicable, the assigning Lender
(or, in the case of a Participant, to the Lender from which the related
participation shall have been purchased) two further duly completed and signed
copies of such Forms 1001, 4224, W-8 or W-9, as the case may be, or successor
and related applicable forms, on or before the date that any such form expires
or becomes obsolete and promptly after the occurrence of any event requiring a
change from the most recent form(s) previously delivered by it to the Borrower
(or, in the case of a Participant, to the Lender from which the related
participation shall have been purchased) in accordance with applicable U.S.
laws and regulations, (ii) in the case of a Non-U.S. Lender that delivers a
statement in the form of Exhibit H (or such other form of statement as shall
have been requested by the Borrower), to deliver to the Borrower and the
Administrative Agent, and if applicable, the assigning Lender, such statement
on an annual basis on the anniversary of the date on which such
<PAGE>   27
                                                                              23



Non-U.S. Lender became a party to this Agreement and to deliver promptly to the
Borrower and the Administrative Agent, and if applicable, the assigning Lender,
such additional statements and forms as shall be reasonably requested by the
Borrower from time to time, and (iii) to notify promptly the Borrower and the
Administrative Agent (or, in the case of a Participant, the Lender from which
the related participation shall have been purchased) if it is no longer able to
deliver, or if it is required to withdraw or cancel, any form or statement
previously delivered by it pursuant to this subsection 2.9(b).  Each Non-U.S.
Lender agrees to indemnify and hold harmless the Borrower from and against any
taxes, penalties, interest or other costs or losses (including, without
limitation, reasonable attorneys' fees and expenses) incurred or payable by the
Borrower as a result of the failure of the Borrower to comply with its
obligations to deduct or withhold any U.S. Taxes from any payments made
pursuant to this Agreement to such Non-U.S. Lender or the Administrative Agent
which failure resulted from the Borrower's reliance on any form, statement,
certificate or other information provided to it by such Non-U.S. Lender
pursuant to clause (B) or clause (ii) of this subsection 2.9(b).  The Borrower
hereby agrees that for so long as a Non-U.S. Lender complies with this
subsection 2.9(e), the Borrower shall not withhold any amounts from any
payments made pursuant to this Agreement to such Non-U.S. Lender, unless the
Borrower reasonably determines that it is required by law to withhold or deduct
any amounts from any payments made to such Non- U.S. Lender pursuant to this
Agreement.  Notwithstanding any other provision of this subsection 2.9(b), a
Non-U.S.  Lender shall not be required to deliver any form or statement
pursuant to the immediately preceding sentences in this subsection 2.9(b) that
such Non-U.S. Lender is not legally able to deliver (it being understood and
agreed that the Borrower shall withhold or deduct such amounts from any
payments made to such Non-U.S. Lender that the Borrower reasonably determines
are required by law).  If any Loan Party other than the Borrower makes any
payment to any Non-U.S.  Lender under any Loan Document, the foregoing
provisions of this subsection 2.9 shall apply to such Non-U.S. Lender and such
Loan Party as if such Loan Party were the Borrower (but a Non-U.S. Lender shall
not be required to provide any form or make any statement to any such Loan
Party unless such Non-U.S. Lender has received a request to do so from such
Loan Party and has a reasonable time to comply with such request).

                 2.10  Administrative Agent's Fee.  The Borrower shall pay to
the Administrative Agent for its own account an annual agent's fee in the
amount agreed between the Borrower and the Administrative Agent, payable on
each of the Second Closing Date and each anniversary of the Closing Date.


                   SECTION 3.  REPRESENTATIONS AND WARRANTIES

                 To induce the Agents and the Lenders to enter into this
Agreement and to make the Loans, the Borrower hereby represents and warrants to
the Agents and each Lender that:

                 3.1  Financial Condition.  The unaudited pro forma balance
sheet of the Borrower as at September 30, 1996 the "Pro Forma Balance Sheet"),
a copy of which has heretofore been furnished to each Lender, was prepared
after giving effect to the
<PAGE>   28
                                                                              24



capitalization of the Borrower, the Acquisition and the transactions
contemplated thereby, the Loans hereunder and the use of the proceeds thereof
and the payment of related fees and expenses.  The Pro Forma Balance Sheet
presents fairly on a pro forma basis the financial position of the Borrower as
at September 30, 1996 assuming that the events and assumptions specified in the
preceding sentence had actually occurred or are true, as the case may be, on
that date and subject to the recording of the Rigs contemplated by the
definition of GAAP.  As of the date of the Pro Forma Balance Sheet, the
Borrower did not have any material obligation, contingent liability or
liability for taxes, or any long-term lease or unusual forward or long-term
commitment, including, without limitation, any interest rate or foreign
currency swap or exchange transaction, which is not reflected in the foregoing
statements or in the notes thereto.

                 3.2  No Change.  (a) Since September 30, 1996 there has been
no development or event which has had or could reasonably be expected to have a
Material Adverse Effect, and (b) during the period from September 30, 1996 to
and including the date hereof no dividends or other distributions have been
declared, paid or made upon the Capital Stock of the Borrower nor has any of
the Capital Stock of the Borrower been redeemed, retired, purchased or
otherwise acquired for value by the Borrower or any of its Subsidiaries.

                 3.3  Existence; Compliance with Law.  Each of the Borrower and
its Subsidiaries (a) is duly organized, validly existing and, in the case of
the corporate Subsidiaries of the Borrower, in good standing under the laws of
the jurisdiction of its organization, (b) has the power and authority, and the
legal right, to own and operate its property, to lease the property it operates
as lessee and to conduct the business in which it is currently engaged, (c) is
duly qualified and, in the case of the corporate Subsidiaries of the Borrower,
in good standing under the laws of each jurisdiction wherein the failure to be
so qualified and in good standing could have a Material Adverse Effect and (d)
is in compliance with all Requirements of Law except to the extent that the
failure to comply therewith could not, in the aggregate, have a Material
Adverse Effect.

                 3.4  Power; Authorization; Enforceable Obligations.  Each of
the Loan Parties has the power and authority, and the legal right, to make,
deliver and perform the Loan Documents to which it is a party and, in the case
of the Borrower, to borrow hereunder and has taken all necessary action to
authorize the borrowings on the terms and conditions of this Agreement and any
Notes and to authorize the execution, delivery and performance of the Loan
Documents to which it is a party.  No consent or authorization of, filing with,
notice to or other act by or in respect of, any Governmental Authority or any
other Person is required in connection with the borrowings hereunder or with
the execution, delivery, performance, validity or enforceability of the Loan
Documents other than the filings necessary to record Liens under the Security
Documents or such as have already been obtained.  This Agreement has been, and
each other Loan Document to which it is a party will be, duly executed and
delivered on behalf of each Loan Party thereto.  This Agreement constitutes,
and each other Loan Document to which it is a party when executed and delivered
will constitute, a legal, valid and binding obligation of each Loan Party
thereto, enforceable against such Loan Party in accordance with its terms,
subject to the effects of bankruptcy, insolvency, fraudulent conveyance,
reorganization, moratorium and other similar laws relating to or affecting
<PAGE>   29
                                                                              25



creditors' rights generally, general equitable principles (whether considered
in a proceeding in equity or at law) and an implied covenant of good faith and
fair dealing.

                 3.5  No Legal Bar.  The execution, delivery and performance of
the Loan Documents to which any Loan Party is a party, the borrowings hereunder
and the use of the proceeds thereof will not violate any Requirement of Law
(the violation of which could reasonably be expected to have a Material Adverse
Effect) or Contractual Obligation of such Loan Party or of any of its
Subsidiaries and will not result in, or require, the creation or imposition of
any Lien on any of its or their respective properties or revenues pursuant to
any such Requirement of Law or Contractual Obligation.

                 3.6  No Material Litigation.  No litigation, investigation or
proceeding of or before any arbitrator or Governmental Authority is pending or,
to the knowledge of the Borrower, threatened by or against the Borrower or any
of its Subsidiaries or against any of its or their respective properties or
revenues, except as disclosed in Schedule 3.6, none of which (a) is with
respect to any of the Loan Documents or any of the transactions contemplated
hereby or thereby, or (b) could reasonably be expected to have a Material
Adverse Effect.

                 3.7  No Default.  Neither the Borrower nor any of its
Subsidiaries is in default under or with respect to any of its Contractual
Obligations in any respect which could reasonably be expected to have a
Material Adverse Effect.  No Default or Event of Default has occurred and is
continuing.

                 3.8  Ownership of Property; Liens.  Each of the Borrower and
its Subsidiaries has good record and marketable title in fee simple to, or a
valid leasehold interest in, all its real property, and good title to, or a
valid leasehold interest in, all its other property (including, without
limitation, the Rigs), and none of such property is subject to any Lien except
as permitted by subsection 6.3.

                 3.9  Intellectual Property.  The Borrower and each of its
Subsidiaries owns, or is licensed to use, all trademarks, tradenames,
copyrights, technology, know-how and processes necessary for the conduct of its
business as currently conducted except for those the failure to own or license
which could not have a Material Adverse Effect (the "Intellectual Property").
No claim has been asserted and is pending by any Person challenging or
questioning the use of any such Intellectual Property or the validity or
effectiveness of any such Intellectual Property, nor does the Borrower know of
any valid basis for any such claim.  The use of such Intellectual Property by
the Borrower and its Subsidiaries does not infringe on the rights of any
Person, except for such claims and infringements that, in the aggregate, do not
have a Material Adverse Effect.

                 3.10  No Burdensome Restrictions.  No Requirement of Law or
Contractual Obligation of the Borrower or any of its Subsidiaries has a
Material Adverse Effect.

                 3.11  Taxes.  Each of the Borrower and its Subsidiaries has
filed or caused to be filed all tax returns which, to the knowledge of the
Borrower, are required to be filed and
<PAGE>   30
                                                                              26



has paid all taxes shown to be due and payable on said returns or on any
assessments made against it or any of its property and all other taxes, fees or
other charges imposed on it or any of its property by any Governmental
Authority (other than any the amount or validity of which are currently being
contested in good faith by appropriate proceedings and with respect to which
reserves in conformity with GAAP have been provided on the books of the
Borrower or its Subsidiaries, as the case may be); no tax Lien has been filed,
and, to the knowledge of the Borrower, no claim is being asserted, with respect
to any such tax, fee or other charge.

                 3.12  Federal Regulations.  No part of the proceeds of any
Loans will be used for "purchasing" or "carrying" any "margin stock" within the
respective meanings of each of the quoted terms under Regulation G or
Regulation U of the Board of Governors of the Federal Reserve System as now and
from time to time hereafter in effect.  If requested by any Lender or the
Administrative Agent, the Borrower will furnish to the Administrative Agent and
each Lender a statement to the foregoing effect in conformity with the
requirements of FR Form G-1 or FR Form U-1 referred to in said Regulation G or
Regulation U, as the case may be.

                 3.13  ERISA.  Neither a Reportable Event nor an "accumulated
funding deficiency" (within the meaning of Section 412 of the Code or Section
302 of ERISA) has occurred during the five-year period prior to the date on
which this representation is made or deemed made with respect to any Plan, and
each Plan has complied in all material respects with the applicable provisions
of ERISA and the Code.  No termination of a Single Employer Plan has occurred,
and no Lien in favor of the PBGC or a Plan has arisen, during such five-year
period.  The present value of all accrued benefits under each Single Employer
Plan (based on those assumptions used to fund such Plans) did not, as of the
last annual valuation date prior to the date on which this representation is
made or deemed made, exceed the value of the assets of such Plan allocable to
such accrued benefits.  Neither the Borrower nor any Commonly Controlled Entity
has had a complete or partial withdrawal from any Multiemployer Plan, and
neither the Borrower nor any Commonly Controlled Entity would become subject to
any liability under ERISA if the Borrower or any such Commonly Controlled
Entity were to withdraw completely from all Multiemployer Plans as of the
valuation date most closely preceding the date on which this representation is
made or deemed made.  No such Multiemployer Plan is in Reorganization or
Insolvent.  None of DeepTech or any of its Subsidiaries maintains, or is
subject to any liabilities or obligations under, any Plan.

                 3.14  Investment Company Act; Other Regulations.  The Borrower
is not an "investment company", or a company "controlled" by an "investment
company", within the meaning of the Investment Company Act of 1940, as amended.
The Borrower is not subject to regulation under any Federal or State statute or
regulation (other than Regulation X of the Board of Governors of the Federal
Reserve System) which limits its ability to incur Indebtedness.

                 3.15  Subsidiaries.  The Borrower has no Subsidiaries on the
date hereof.
<PAGE>   31
                                                                              27




                 3.16  Purpose of Loans.  The proceeds of the Loans shall be
used by the Borrower for the purposes set forth in subsection 2.2.

                 3.17  Environmental Matters.  Except as set forth on Schedule
3.17:

                 (a)  The facilities and properties owned, leased or operated
         by the Borrower or any of its Subsidiaries (the "Properties") do not
         contain, and have not previously contained, any Materials of
         Environmental Concern in amounts or concentrations which (i)
         constitute or constituted a violation of, or (ii) could reasonably be
         expected to give rise to liability under, any Environmental Law.

                 (b)  The Properties and all operations at the Properties are
         in compliance, and have in the last five years been in compliance,
         with all applicable Environmental Laws, and there is no contamination
         at, under or about the Properties or violation of any Environmental
         Law with respect to the Properties or the business operated by the
         Borrower or any of its Subsidiaries (the "Business") which could

to exercise such powers and perform such duties as are expressly delegated to
each of the Agents by the terms of this Agreement and the other Loan Documents,
together with such other powers as are reasonably incidental thereto.
Notwithstanding any provision to the contrary elsewhere in this Agreement, none
of the Agents shall have any duties or responsibilities, except those expressly
set forth herein, or any fiduciary relationship with any Lender, and no implied
covenants, functions, responsibilities, duties, obligations or liabilities
shall be read into this Agreement or any other Loan Document or otherwise exist

willful misconduct) or (ii) responsible in any manner to any of the Lenders for
any recitals, statements, representations or warranties made by the Borrower or
any officer thereof contained in this Agreement or any other Loan Document or
in any certificate, report, statement or other document referred to or provided
for in, or received by such Agent under or in connection with, this Agreement
or any other Loan Document or for the value, validity, effectiveness,
genuineness, enforceability or sufficiency of this Agreement or any other Loan
Document or for any failure of the Borrower to perform its obligations
hereunder or thereunder.  None of the Agents shall be under any obligation to
any Lender to ascertain or to inquire as to the observance or performance of
any of the agreements contained in, or conditions of, this Agreement or any
other Loan Document, or to inspect the properties, books or records of the
Borrower.

                 8.4  Reliance by Agents.  The Agents shall be entitled to
rely, and shall be fully protected in relying, upon any Note, writing,
resolution, notice, consent, certificate, affidavit, letter, telecopy, telex or

by the proper Person or Persons and upon advice and statements of legal counsel
(including, without limitation, counsel to the Borrower), independent
accountants and other experts selected by such Agent.  The Agents may deem and
treat the payee of any Note as the owner thereof for all purposes unless a
written notice of assignment, negotiation or transfer thereof shall have been
filed with such Agent.  The Agents shall be fully justified in failing or
refusing to take any action under this Agreement or any other Loan Document
unless it shall first receive such advice or concurrence of the Required
Lenders as it deems appropriate or it shall first be indemnified to its
satisfaction by the Lenders against any and all liability and expense which may
be incurred by it by reason of taking or continuing to take any such action.
The Agents shall in all cases be fully protected in acting, or in refraining

or failure to act pursuant thereto shall be binding upon all the Lenders and
all future holders of the Loans.

                 8.5  Notice of Default.  No Agent shall be deemed to have
knowledge or notice of the occurrence of any Default or Event of Default
hereunder unless such Agent has received notice from a Lender or the Borrower
referring to this Agreement, describing such Default or Event of Default and
stating that such notice is a "notice of default".  In the event that any Agent
receives such a notice, such Agent shall give notice thereof to the Lenders.
Each Agent shall take such action with respect to such Default or Event of
Default as shall be reasonably directed by the Required Lenders; provided that
unless and until such Agent shall have received such directions, such Agent may
(but shall not be obligated to) take such action, or refrain from taking such
action, with respect to such Default or Event of Default as it shall deem
advisable in the best interests of the Lenders.

                 8.6  Non-Reliance on Agents and Other Lenders.  Each Lender
expressly acknowledges that neither any of the Agents nor any of their
officers, directors, employees, agents, attorneys-in-fact or Affiliates has
made any representations or warranties to it and that no act by any of the
Agents hereafter taken, including any review of the affairs of the Borrower,
shall be deemed to constitute any representation or warranty by any of the
Agents to any Lender.  Each Lender represents to each of the Agents that it
has, independently and without reliance upon any of the Agents or any other
Lender, and based on such documents and information as it has deemed
appropriate, made its own appraisal of and investigation into the business,
operations, property, financial and other condition and creditworthiness of the
Borrower and made its own decision to make its Loans hereunder and enter into
this Agreement.  Each Lender also represents that it will, independently and
without reliance upon any of the Agents or any other Lender, and based on such
documents and information as it shall deem appropriate at the time, continue to
make its own credit analysis, appraisals and decisions in taking or not taking
action under this Agreement and the other Loan Documents, and to make such
investigation as it deems necessary to inform itself as to the business,
operations, property, financial and other condition and creditworthiness of the
Borrower.  Except for notices, reports and other documents expressly required
to be furnished to the Lenders by any of the Agents hereunder, none of the
Agents shall have any duty or responsibility to provide any Lender with any
credit or other information concerning the business, operations, property,
condition (financial or otherwise), prospects or
<PAGE>   53
                                                                              49



creditworthiness of the Borrower which may come into the possession of such
Agent or any of its officers, directors, employees, agents, attorneys-in-fact
or Affiliates.

                 8.7  Indemnification.  The Lenders agree to indemnify each of
the Agents in their respective capacities as such (to the extent not reimbursed
by the Borrower and without limiting the obligation of the Borrower to do so),
ratably according to their respective Commitment Percentages in effect on the
date on which indemnification is sought, from and against any and all
liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements of any kind whatsoever which may at any
time (including, without limitation, at any time following the payment of the
Loans) be imposed on, incurred by or asserted against any of the Agents in any
way relating to or arising out of, the Commitments, this Agreement, any of the
other Loan Documents or any documents contemplated by or referred to herein or
therein or the transactions contemplated hereby or thereby or any action taken
or omitted by any of the Agents under or in connection with any of the
foregoing; provided that no Lender shall be liable for the payment of any
portion of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements resulting solely from such
Agent's gross negligence or willful misconduct.  The agreements in this
subsection shall survive the payment of the Loans and all other amounts payable
hereunder.

                 8.8  Administrative Agent, Collateral and Documentation Agent
and Arranger in Their Individual Capacities.  The Administrative Agent, the
Collateral and Documentation Agent, the Arranger and their respective
Affiliates may make loans to, accept deposits from and generally engage in any
kind of business with the Borrower as though the Administrative Agent, the
Collateral and Documentation Agent and the Arranger were not acting in such
capacities hereunder and under the other Loan Documents.  With respect to the
Loans made by it, the Administrative Agent and the Collateral and Documentation
Agent shall have the same rights and powers under this Agreement and the other
Loan Documents as any Lender and may exercise the same as though it were not
the Administrative Agent and the Collateral and Documentation Agent, and the
terms "Lender" and "Lenders" shall include the Administrative Agent and the
Collateral and Documentation Agent in their individual capacities.

                 8.9  Successor Administrative Agent and Collateral and
Documentation Agent.  The Administrative Agent or the Collateral and
Documentation Agent may resign as Administrative Agent or Collateral and
Documentation Agent, as the case may be, upon 10 days' notice to the Lenders.
If the Administrative Agent shall resign as Administrative Agent under this
Agreement and the other Loan Documents or if the Collateral and Documentation
Agent shall resign as Collateral and Documentation Agent under this Agreement
and the other Loan Documents, then the Required Lenders shall appoint from
among the Lenders a successor agent for the Lenders (or, so long as Lehman
Commercial Paper Inc. is the Administrative Agent and/or the Collateral and
Documentation Agent, Lehman Commercial Paper Inc. shall appoint a financial
institution as successor agent for the Lenders), which successor agent
(provided that it shall have been approved by the Borrower), shall succeed to
the rights, powers and duties of the Administrative Agent or the Collateral and
Documentation Agent, as the case may be, hereunder.  Effective upon such
<PAGE>   54
                                                                              50



appointment and approval, the term "Administrative Agent" or "Collateral and
Documentation Agent", as the case may be, shall mean such successor agent, and
the former Administrative Agent's or Collateral and Documentation Agent's, as
the case may be, rights, powers and duties as Administrative Agent or
Collateral and Documentation Agent, as the case may be, shall be terminated,
without any other or further act or deed on the part of such former
Administrative Agent or Collateral and Documentation Agent, as the case may be,
or any of the parties to this Agreement or any holders of the Loans.  After any
retiring Administrative Agent's or Collateral and Documentation Agent's
resignation as Administrative Agent or Collateral and Documentation Agent, as
the case may be, the provisions of this Section 8 shall inure to its benefit as
to any actions taken or omitted to be taken by it while it was Administrative
Agent or Collateral and Documentation Agent, as the case may be, under this
Agreement and the other Loan Documents.

                 8.10  The Arranger.  Except as expressly set forth herein, the
Arranger, in its capacity as such, shall have no duties or responsibilities,
and shall incur no liabilities, under this Agreement or the other Loan
Documents.


                           SECTION 9.  MISCELLANEOUS

                 9.1  Amendments and Waivers.  Neither this Agreement nor any
other Loan Document, nor any terms hereof or thereof may be amended,
supplemented or modified except in accordance with the provisions of this
subsection.  The Required Lenders may, or, with the written consent of the
Required Lenders, the Administrative Agent may, from time to time, (a) enter
into with the Borrower written amendments, supplements or modifications hereto
and to the other Loan Documents for the purpose of adding any provisions to
this Agreement or the other Loan Documents or changing in any manner the rights
of the Lenders or of the Borrower hereunder or thereunder or (b) waive, on such
terms and conditions as the Required Lenders or the Administrative Agent, as
the case may be, may specify in such instrument, any of the requirements of
this Agreement or the other Loan Documents or any Default or Event of Default
and its consequences; provided, however, that no such waiver and no such
amendment, supplement or modification shall (i) reduce the amount or extend the
scheduled date of maturity of any Loan or of any installment thereof, or reduce
the stated rate of any interest or fee payable hereunder or extend the
scheduled date of any payment thereof, in each case without the consent of each
Lender affected thereby, or (ii) amend, modify or waive any provision of this
subsection or reduce the percentage specified in the definition of Required
Lenders, or consent to the assignment or transfer by the Borrower of any of its
rights and obligations under this Agreement and the other Loan Documents or
release all or substantially all of the Collateral, in each case without the
written consent of all the Lenders, or (iii) amend, modify or waive any
provision of Section 8 without the written consent of the then Administrative
Agent and the then Collateral and Documentation Agent, or (iv) release any
material portion of the Collateral or waive any provision of subsection 2.5, in
each case without the written consent of the Required Lenders, or (v) amend,
modify or waive any provision of this Agreement or any other Loan Document
which would directly and adversely affect the Arranger or the Collateral and
Documentation Agent without the written consent of the then Arranger or
<PAGE>   55
                                                                              51



Collateral and Documentation Agent, as the case may be.  Any such waiver and
any such amendment, supplement or modification shall apply equally to each of
the Lenders and shall be binding upon the Borrower, the Lenders, the Agents and
all future holders of the Loans.  In the case of any waiver, the Borrower, the
Lenders and the Agents shall be restored to their former positions and rights
hereunder and under the other Loan Documents, and any Default or Event of
Default waived shall be deemed to be cured and not continuing; no such waiver
shall extend to any subsequent or other Default or Event of Default or impair
any right consequent thereon.

provided that any notice, request or demand to or upon the Administrative Agent

                 9.3  No Waiver; Cumulative Remedies.  No failure to exercise
and no delay in exercising, on the part of any Agent or any Lender, any right,
remedy, power or privilege hereunder or under the other Loan Documents shall
operate as a waiver thereof; nor shall any single or partial exercise of any
right, remedy, power or privilege hereunder preclude any other or further
exercise thereof or the exercise of any other right, remedy, power or
privilege.  The rights, remedies, powers and privileges herein provided are
cumulative and not exclusive of any rights, remedies, powers and privileges
provided by law.

                 9.4  Survival of Representations and Warranties.  All
representations and warranties made hereunder, in the other Loan Documents and
in any document, certificate or statement delivered pursuant hereto or in

                 9.5  Payment of Expenses and Taxes.  The Borrower agrees (a)
to pay or reimburse each of the Agents for all its out-of-pocket costs and
expenses incurred in connection with the development, preparation and execution
of, and any amendment, supplement or modification to, this Agreement and the
other Loan Documents and any other documents prepared in connection herewith or
therewith, and the consummation and administration of the transactions
contemplated hereby and thereby, including, without limitation, the reasonable
fees and disbursements of counsel to any of the Agents, (b) to pay or reimburse
each Lender and each Agent for all its costs and expenses incurred in
connection with the enforcement or preservation of any rights under this
Agreement, the other Loan Documents and any such other documents, including,
without limitation, the fees and disbursements of counsel to each Lender and of
counsel to any Agent, (c) to pay, indemnify, and hold each Lender and each
Agent harmless from, any and all recording and filing fees and any and all
liabilities with respect to, or resulting from any delay in paying, stamp,
excise and other taxes, if any, which may be payable or determined to be
payable in connection with the execution and delivery of, or consummation or
administration of any of the transactions contemplated by, or any amendment,

Acquisition and any such other documents,

                                                                              53



including, without limitation, any of the foregoing relating to the violation
of, noncompliance with or liability under, any Environmental Law applicable to
the operations of the Borrower, any of its Subsidiaries or any of the
Properties (all the foregoing in this clause (d), collectively, the
"indemnified liabilities"), provided that the Borrower shall have no obligation
hereunder to any Agent or any Lender with respect to indemnified liabilities
arising from the gross negligence or willful misconduct of such Agent or any
such Lender.  The agreements in this subsection shall survive repayment of the
Loans and all other amounts payable hereunder.

                 9.6  Successors and Assigns; Participations and Assignments.
(a)  This Agreement shall be binding upon and inure to the benefit of the
Borrower, the Lenders, the Agents and their respective successors and assigns,
except that the Borrower may not assign or transfer any of its rights or
obligations under this Agreement without the prior written consent of each
Lender.

                 (b)  Any Lender may, in the ordinary course of its business
and in accordance with applicable law, at any time sell to one or more banks or
other entities ("Participants") participating interests in any Loan owing to
such Lender or any other interest of such Lender hereunder and under the other
Loan Documents.  In the event of any such sale by a Lender of a participating
interest to a Participant, such Lender's obligations under this Agreement to
the other parties to this Agreement shall remain unchanged, such Lender shall
remain solely responsible for the performance thereof, such Lender shall remain
the holder of any such Loan for all purposes under this Agreement and the other
Loan Documents, and the Borrower and the Agents shall continue to deal solely
and directly with such Lender in connection with such Lender's rights and
obligations under this Agreement and the other Loan Documents.  No Lender shall
be entitled to create in favor of any Participant, in the participation
agreement pursuant to which such Participant's participating interest shall be
created or otherwise, any right to vote on, consent to or approve any matter
relating to this Agreement or any other Loan Document except for those
specified in clauses (i) and (ii) of the proviso to subsection 9.1.  The
Borrower agrees that if amounts outstanding under this Agreement are due or
unpaid, or shall have been declared or shall have become due and payable upon
the occurrence of an Event of Default, each Participant shall, to the maximum
extent permitted by applicable law, be deemed to have the right of setoff in
respect of its participating interest in amounts owing under this Agreement to
the same extent as if the amount of its participating interest were owing
directly to it as a Lender under this Agreement, provided that, in purchasing
such participating interest, such Participant shall be deemed to have agreed to
share with the Lenders the proceeds thereof as provided in subsection 9.7(a) as
fully as if it were a Lender hereunder.  The Borrower also agrees that each
Participant shall be entitled to the benefits of subsections 2.9 with respect
to its participation in the Loans outstanding from time to time as if it was a
Lender; provided that such Participant shall have complied with the
requirements of said subsection and provided, further, that no Participant
shall be entitled to receive any greater amount pursuant to any such subsection
than the transferor Lender would have been entitled to receive in respect of
the amount of the participation transferred by such transferor Lender to such
Participant had no such transfer occurred.

                 (c)  Any Lender may, in the ordinary course of its business
and in accordance with applicable law, at any time and from time to time assign
to any Lender or any affiliate thereof or, with the consent of the
Administrative Agent and the Arranger (which shall not be unreasonably
withheld), to an additional bank or financial institution (an "Assignee") all
or any part of its rights and obligations under this Agreement and the other
Loan Documents pursuant to an Assignment and Acceptance, substantially in the
form of Exhibit F, executed by such Assignee, such assigning Lender (and, in
the case of an Assignee that is not then a Lender or an affiliate thereof, by
the Administrative Agent and the Arranger) and delivered to the Administrative
Agent for its acceptance and recording in the Register, provided that, in the
case of any such assignment to an additional bank or financial institution, (A)
the aggregate principal amount of the Loans being assigned and, if such
assignment is of less than all of the rights and obligations of the assigning
Lender, the aggregate principal amount of the Loans remaining with the
assigning Lender are each not less than $2,500,000 (or such lesser amount as
may be agreed to by the Borrower, the Administrative Agent and the Arranger)
and (B) each Assignee which is a Non-U.S. Lender shall comply with the
provisions of clause (A) of subsection 2.9(d) hereof, or, with the prior
written consent of the Borrower, which shall not be unreasonably withheld, the
provisions of clause (B) of subsection 2.9(d) hereof (and, in either case, with
all of the other provisions of subsection 2.9(d) hereof).  Upon such execution,
delivery, acceptance and recording, from and after the effective date
determined pursuant to such Assignment and Acceptance, (x) the Assignee
thereunder shall be a party hereto and, to the extent provided in such
Assignment and Acceptance, have the rights and obligations of a Lender
hereunder and (y) the assigning Lender thereunder shall, to the extent provided
in such Assignment and Acceptance, be released from its obligations under this
Agreement (and, in the case of an Assignment and Acceptance covering all or the
remaining portion of an assigning Lender's rights and obligations under this
Agreement, such assigning Lender shall cease to be a party hereto).

                 (d)  Any Non-U.S. Lender (other than a Participant or an
Assignee, with respect to which the Borrower has not provided the prior written
consent described in clause (B) of the proviso to the first sentence of
subsection 9.6(c), in the case of an Assignee) that could become completely
exempt from withholding of any U.S. Taxes in respect of payment of any interest
due to such Non-U.S. Lender under this Agreement if the Note held by such
Non-U.S. Lender were in registered form for U.S. federal income tax purposes
may request the Borrower (through the Administrative Agent), and the Borrower
agrees thereupon, to exchange any Note held by such Non-U.S. Lender, or to
issue to such Non-U.S. Lender on the date it becomes a party to this Agreement,
Note registered as provided in paragraph (e) below and substantially in the
form of Exhibit I (a "Qualified Non-U.S. Lender Note").  Qualified Non-U.S.
Lender Notes may not be exchanged for promissory notes that are not Qualified
Non-U.S. Lender Notes.

                 (e)  A Qualified Non-U.S. Lender Note and the Obligations
evidenced thereby may be assigned or otherwise transferred in whole or in part
only by registration of such assignment or transfer of such Qualified Non-U.S.
Lender Note and the Obligations evidenced thereby on the Register (and each
Qualified Non-U.S. Lender Note shall expressly so provide).  Any assignment or
transfer of all or part of such Obligation and the Qualified Non-U.S. Lender
Note evidencing the same shall be registered on the Register only upon
<PAGE>   59
                                                                              55



surrender for registration of assignment or transfer of the Qualified Non-U.S.
Lender Note evidencing such Obligation, duly endorsed by (or accompanied by a
written instrument of assignment or transfer duly executed by) the holder
thereof (a "Qualified Non-U.S. Lender Noteholder"), and thereupon a new
Qualified Non-U.S. Lender Note in the same aggregate principal amount shall be
issued to the designated Assignee and the old Qualified Non-U.S. Lender Note
shall be returned to the Borrower marked "cancelled".  No assignment of a
Qualified Non-U.S. Lender Note and the Obligations evidenced thereby shall be
effective unless it shall have been recorded in the Register by the
Administrative Agent as provided in this subsection 9.6(e).

                 (f)  The Administrative Agent, on behalf of the Borrower,
shall maintain at the address of the Administrative Agent referred to in
subsection 9.2 a copy of each Assignment and Acceptance delivered to it and a
register (the "Register") for the recordation of the names and addresses of the
Lenders and the principal amounts of the Loans owing to, each Lender from time
to time and the registered owners of the Obligations evidenced by the Qualified
Non-U.S. Lender Notes (including Qualified Non-U.S. Lender Noteholders).  The
entries in the Register shall be conclusive, in the absence of manifest error,
and the Borrower, the Administrative Agent and the Lenders may treat each
Person whose name is recorded in the Register as the owner of a Loan, a
Qualified Non-U.S. Lender Note or other obligation hereunder as the owner
thereof for all purposes of this Agreement and the other Loan Documents,
notwithstanding any notice to the contrary.  Any assignment of any Loan or
other obligation hereunder not evidenced by a Note shall be effective only upon
appropriate entries with respect thereto being made in the Register.  The
Register shall be available for inspection by the Borrower or any Lender at any
reasonable time and from time to time upon reasonable prior notice.

                 (g)  Upon its receipt of an Assignment and Acceptance executed
by an assigning Lender and an Assignee (and, in the case of an Assignee that is
not then a Lender or an affiliate thereof, by the Administrative Agent)
together with payment to the Administrative Agent of a registration and
processing fee of $2,000, the Administrative Agent shall (i) promptly accept
such Assignment and Acceptance and (ii) on the effective date determined
pursuant thereto record the information contained therein in the Register and
give notice of such acceptance and recordation to the Lenders and the Borrower.

                 (h)  The Borrower authorizes each Lender to disclose to any
Participant or Assignee (each, a "Transferee") and any prospective Transferee,
subject to the provisions of subsection 9.15, any and all financial information
in such Lender's possession concerning the Borrower and its Affiliates which
has been delivered to such Lender by or on behalf of the Borrower pursuant to
this Agreement or which has been delivered to such Lender by or on behalf of
the Borrower in connection with such Lender's credit evaluation of the Borrower
and its Affiliates prior to becoming a party to this Agreement.

                 (i)  If, pursuant to this subsection 9.6, any interest in this
Agreement or any Loan is transferred to any Transferee which would be a
Non-U.S. Lender upon the effectiveness of such transfer, the assigning Lender
shall cause such Transferee, concurrently with the effectiveness of such
transfer, (i) to represent to the assigning Lender (for the
<PAGE>   60
                                                                              56



benefit of the assigning Lender, the Administrative Agent and the Borrower)
that under applicable law and treaties no U.S. Taxes will be required to be
withheld by the Administrative Agent, the Borrower or the assigning Lender with
respect to any payments to be made to such Transferee in respect of the Loans,
(ii) to furnish to the assigning Lender (and, in the case of any Assignee
registered in the Register, the Administrative Agent and the Borrower such
Internal Revenue Service Forms required to be furnished pursuant to subsection
2.9(d) and (iii) to agree (for the benefit of the assigning Lender, the
Administrative Agent and the Borrower) to be bound by the provisions of
subsection 2.9(d).

                 (j)  For avoidance of doubt, the parties to this Agreement
acknowledge that the provisions of this subsection concerning assignments of
Loans and Notes relate only to absolute assignments and that such provisions do
not prohibit assignments creating security interests, including, without
limitation, any pledge or assignment by a Lender of any Loan or Note to any
Federal Reserve Bank in accordance with applicable law.

                 9.7  Adjustments; Set-off.  (a)  If any Lender (a "benefitted
Lender") shall at any time receive any payment of all or part of its Loans
(otherwise than as permitted in subsection 2.5(d)), or interest thereon, or
receive any collateral in respect thereof (whether voluntarily or
involuntarily, by set-off, pursuant to events or proceedings of the nature
referred to in Section 7(f), or otherwise), in a greater proportion than any
such payment to or collateral received by any other Lender, if any, in respect
of such other Lender's Loans, or interest thereon, such benefitted Lender shall
purchase for cash from the other Lenders a participating interest in such
portion of each such other Lender's Loan, or shall provide such other Lenders
with the benefits of any such collateral, or the proceeds thereof, as shall be
necessary to cause such benefitted Lender to share the excess payment or
benefits of such collateral or proceeds ratably with each of the Lenders;
provided, however, that if all or any portion of such excess payment or
benefits is thereafter recovered from such benefitted Lender, such purchase
shall be rescinded, and the purchase price and benefits returned, to the extent
of such recovery, but without interest.

                 (b)  In addition to any rights and remedies of the Lenders
provided by law, each Lender shall have the right, without prior notice to the
Borrower, any such notice being expressly waived by the Borrower to the extent
permitted by applicable law, upon any amount becoming due and payable by the
Borrower hereunder (whether at the stated maturity, by acceleration or
otherwise) to set-off and appropriate and apply against such amount any and all
deposits (general or special, time or demand, provisional or final), in any
currency, and any other credits, indebtedness or claims, in any currency, in
each case whether direct or indirect, absolute or contingent, matured or
unmatured, at any time held or owing by such Lender or any branch or agency
thereof to or for the credit or the account of the Borrower.  Each Lender
agrees promptly to notify the Borrower and the Administrative Agent after any
such set-off and application made by such Lender, provided that the failure to
give such notice shall not affect the validity of such set-off and application.

                 9.12  Submission To Jurisdiction; Waivers.  The Borrower
hereby irrevocably and unconditionally:

                 (a)  submits for itself and its property in any legal action
         or proceeding relating to this Agreement and the other Loan Documents

                                                                              58



                 (e)  waives, to the maximum extent not prohibited by law, any
         right it may have to claim or recover in any legal action or
         proceeding referred to in this subsection any special, exemplary,

                 9.13  Acknowledgements.  The Borrower hereby acknowledges
that:

                 (a)  it has been advised by counsel in the negotiation,
         execution and delivery of this Agreement and the other Loan Documents;

                 (b)  none of the Agents nor any Lender has any fiduciary
         relationship with or duty to the Borrower arising out of or in
         connection with this Agreement or any of the other Loan Documents, and
         the relationship between any of the Agents and the Lenders, on one
         hand, and the Borrower, on the other hand, in connection herewith or
         therewith is solely that of debtor and creditor; and

                 (c)  no joint venture is created hereby or by the other Loan
         Documents or otherwise exists by virtue of the transactions
         contemplated hereby among the Lenders or among the Borrower and the
         Lenders.

                 9.14  WAIVERS OF JURY TRIAL.  THE BORROWER, THE AGENTS, THE
LENDERS AND THE OTHER PARTIES HERETO HEREBY IRREVOCABLY AND UNCONDITIONALLY
WAIVE TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS
AGREEMENT OR ANY OTHER LOAN DOCUMENT AND FOR ANY COUNTERCLAIM THEREIN.

                 9.15  Confidentiality.  Each Lender agrees to keep
confidential all non-public information provided to it by the Borrower pursuant
to this Agreement that is designated by the Borrower in writing as
confidential; provided that nothing herein shall prevent any Lender from
disclosing any such information (i) to any Agent or any other Lender, (ii) to
any Transferee which receives such information having been made aware of the
confidential nature thereof, (iii) to its employees, directors, agents,
attorneys, accountants and other professional advisors, (iv) upon the request
or demand of any Governmental Authority having jurisdiction over such Lender,
(v) in response to any order of any court or other Governmental Authority or as
may otherwise be required pursuant to any Requirement of Law, (vi) which has
been publicly disclosed other than in breach of this Agreement, or (vii) in

                 9.16  Usury Savings Clause.  It is the intention of the
parties hereto to comply with applicable usury laws (now or hereafter enacted);
accordingly, notwithstanding any provision to the contrary in this Agreement,
any Notes, any of the other Loan Documents or any other document related hereto
or thereto, in no event shall this Agreement or any such other document require
the payment or permit the collection of interest in excess of the maximum
amount permitted by such laws.  If from any circumstances whatsoever,
fulfillment of any provision of this Agreement, any Notes, any of the other
Loan Documents or of any other document pertaining hereto or thereto, shall
involve transcending the limit of validity prescribed by applicable law for the
collection or charging of interest, then, ipso
<PAGE>   63
                                                                              59



facto, the obligation to be fulfilled shall be reduced to the limit of such
validity, and if from any such circumstances the Agents and the Lenders shall
ever receive anything of value as interest or deemed interest by applicable law
under this Agreement, any Notes, any of the other Loan Documents or any other
document pertaining hereto or otherwise an amount that would exceed the highest
lawful rate, such amount that would be excessive interest shall be applied to
the reduction of the principal amount owing under the Loans or on account of
any other indebtedness of the Borrower, and not to the payment of interest, or
if such excessive interest exceeds the unpaid balance of principal of such
indebtedness, such excess shall be refunded to the Borrower.  In determining
whether or not the interest paid or payable with respect to any indebtedness of
the Borrower to the Agents and the Lenders, under any specified contingency,
exceeds the Highest Lawful Rate (as hereinafter defined), the Borrower, the
Agents and the Lenders shall, to the maximum extent permitted by applicable
law, (a) characterize any non-principal payment as an expense, fee or premium
rather than as interest, (b) exclude voluntary prepayments and the effects
thereof, (c) amortize, prorate, allocate and spread the total amount of
interest throughout the full term of such indebtedness so that interest thereon
does not exceed the maximum amount permitted by applicable law, and/or (d)
allocate interest between portions of such indebtedness, to the end that no
such portion shall bear interest at a rate greater than that permitted by
applicable law.

                 To the extent that Article 5069-1.04 of the Texas Revised
Civil Statutes is relevant to the Agents and the Lenders for the purpose of
determining the Highest Lawful Rate, the Agents and the Lenders hereby elect to
determine the applicable rate ceiling under such Article by the indicated
(weekly) rate ceiling form time to time in effect.  Nothing set forth in this
subsection 9.16 is intended to or shall limit the effect or operation of
subsection 9.11.

                 For purposes of this subsection 9.16, "Highest Lawful Rate"
shall mean the maximum rate of nonusurious interest that may be contracted for,
taken, reserved or received on the Loans under laws applicable to the Agents
and the Lenders.
