                    INFORMATION TO BE INCLUDED IN THE REPORT
 
ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS.
 
     On April 29, 1996, the stockholders of Diamond Offshore Drilling, Inc., a
Delaware corporation ("Diamond Offshore") (NYSE: DO), approved the issuance of
up to 18,000,000 shares of the Common Stock, par value $0.01 per share, of
Diamond Offshore ("Diamond Offshore Common Stock") in connection with the
acquisition (the "Acquisition") by Diamond Offshore of Arethusa (Off-Shore)
Limited, a Bermuda company ("Arethusa"), which approval was a condition
precedent to consummation of the Acquisition, and the shareholders of Arethusa
adopted and approved the Amalgamation Agreement, dated as of February 9, 1996
(the "Amalgamation Agreement"), between Arethusa and AO Acquisition Limited, a
Bermuda company and an indirect wholly owned subsidiary of Diamond Offshore ("AO
Acquisition"), which adoption and approval was a condition precedent to
consummation of the Acquisition, and ratified the Plan of Acquisition dated as
of February 9, 1996 (the "Plan of Acquisition") among Diamond Offshore, Diamond
Offshore (USA) Inc., a Delaware corporation and a direct wholly owned subsidiary
of Diamond Offshore and the parent of AO Acquisition ("Diamond Offshore (USA)"),
AO Acquisition and Arethusa, as amended by Amendment No. 1 to the Plan of
Acquisition ("Amendment No. 1 to the Plan of Acquisition"), and the Fee
Agreement dated as of February 9, 1996 (the "Fee Agreement") between Diamond
Offshore and Arethusa, as amended by Amendment No. 1 to the Fee Agreement
("Amendment No. 1 to the Fee Agreement"). The Acquisition was consummated on
April 29, 1996, on which date the Registrar of Companies of Bermuda issued a
Certificate of Amalgamation of Arethusa with AO Acquisition, which amalgamated
company continued under the laws of Bermuda under the name Diamond Offshore
Exploration (Bermuda) Limited. The time of the issuance of such Certificate of
Amalgamation was the effective time of the Acquisition (the "Effective Time").
 
     In accordance with the terms of the Acquisition, each share of Arethusa
Common Stock, par value $0.10 per share ("Arethusa Common Stock"), was canceled
and ceased to exist and each former holder of Arethusa Common Stock is entitled
to receive in consideration of each share of Arethusa Common Stock so canceled
 .88 (the "Amalgamation Ratio") shares of Diamond Offshore Common Stock. Such
transaction will not constitute a tax-free reorganization within the meaning of
Section 368(a) of the Internal Revenue Code of 1986, as amended (the "Code"),
and as such, former Arethusa shareholders who are subject to taxation under the
Code will recognize gain or loss equal to the difference between (i) the fair
market value of the Diamond Offshore Common Stock delivered to such shareholders
plus any cash received in lieu of fractional shares and (ii) such shareholders'
adjusted bases in their Arethusa Common Stock. At the close of business on April
2, 1996, there were 20,333,345 shares of Arethusa Common Stock outstanding. The
Amalgamation Ratio was determined through negotiation, based upon estimates of
each company's respective net asset value, each company's current financial
condition, operations and prospects, and the relationship of the historical
market price per share of Diamond Offshore Common Stock to historical market
prices per share of Arethusa Common Stock. Diamond Offshore agreed to issue and
sell to Diamond Offshore (USA) the requisite number of shares of Diamond
Offshore Common Stock, up to 18,000,000 such shares, required pursuant to the
terms of the Acquisition, at the fair market value thereof (determined based
upon the closing price per share of Diamond Offshore Common Stock on the New
York Stock Exchange on April 26, 1996) in consideration of the issuance of a
non-negotiable promissory note by Diamond Offshore (USA) to Diamond Offshore due
eight years after the Effective Time of the Acquisition, bearing interest at a
rate equal to the Federal mid-term rate (within the meaning of Section
1247(d)(1)(A) of the Code) applicable to transactions occurring during April
1996, which rate is 5.88% per annum. Diamond Offshore (USA) agreed to contribute
such shares of Diamond Offshore Common Stock to the capital of AO Acquisition
for delivery to former Arethusa shareholders in consideration of their shares of
Arethusa Common Stock.

     Arethusa owned a fleet of 11 mobile offshore drilling rigs and operated two
additional mobile offshore drilling rigs pursuant to bareboat charters. The
Arethusa fleet consisted of eight semisubmersible rigs and five jack-up rigs.
The former Arethusa fleet was used to provide drilling services worldwide to
international and government-controlled oil and gas companies, which use Diamond
Offshore intends substantially to continue.

              NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS
 
1. INTERIM FINANCIAL STATEMENTS
 
     The condensed consolidated financial statements for the interim periods
shown in this report have not been audited by independent public accountants
but, in the opinion of management, all adjustments necessary for the fair
presentation of these financial statements have been made. All such adjustments
are of a normal recurring nature. Results of operations for interim periods are
not necessarily indicative of results to be expected for the full fiscal year.
 
     The condensed consolidated financial statements should be read in
connection with the consolidated financial statements of Arethusa (Off-Shore)
Limited ("Arethusa") as of September 30, 1995 and 1994, and for each of the
three years in the period ended September 30, 1995 and the related notes
thereto, included elsewhere herein.
 
2. PENDING MERGER OF ARETHUSA AND DIAMOND OFFSHORE DRILLING, INC.
 
     On February 9, 1996, Arethusa and Diamond Offshore Drilling, Inc. ("Diamond
Offshore") executed and delivered definitive agreements in connection with the
previously announced proposed merger of the two companies. Merrill Lynch and CS
First Boston, financial advisers to Arethusa and Diamond Offshore, respectively,
have each rendered a fairness opinion in respect of the transaction and each
company's Board of Directors has resolved to recommend the transaction to its
shareholders.
 
     Under the proposed merger each Arethusa share would be exchanged for .88
share of Diamond Offshore on a taxable basis to Arethusa's United States
shareholders. The transaction is subject to approval by the shareholders of each
company at meetings presently expected to be held in April. Commitments to vote
in favor of the merger have been made by shareholders representing approximately
47% of Arethusa's shares and by Loews Corporation, representing approximately
70% of Diamond Offshore shares. If the Plan of Acquisition is terminated under
certain circumstances, Arethusa must pay to Diamond Offshore a fee of up to $18
million.
 
     Upon successful consummation of the merger, options awarded to officers,
directors and employees of Arethusa will become fully vested and exercisable.
Also, Arethusa Off-Shore Company ("AOC"), a wholly owned subsidiary of Arethusa,
has entered into executive severance agreements with certain executive officers
and has amended its severance policy for most shore based employees which will
provide payment of certain additional benefits to the employees if they are
terminated following the merger.
 
     Additionally, on February 9, 1996 Arethusa declared a cash dividend of $.25
per common share payable on March 15 to shareholders of record as of March 1,
1996.
 
     Additionally, subject to approval by Arethusa shareholders and to a
successful merger, the exercise price of options granted under the 1993 Employee
Stock Option Plan (approximately 462,000 shares granted) would be reduced by $3
per share. In the event the option exercise price is reduced to $7 per share,
Arethusa would be required to record compensation expense in its financial
statements for the difference between the revised exercise price of $7 per share
and the market value on the date approval is received from shareholders. To the
extent the market value of Arethusa shares continues to increase above the
exercise price there will be an increased charge to compensation expense.
 
3. ACQUISITION OF THE ARETHUSA YATZY
 
     In May 1995, Arethusa acquired the Arethusa Yatzy (see footnote 4 to
Arethusa's September 30, 1995 Annual Report on Form 10-K). The following
unaudited pro forma income statement data for the three months ended December
31, 1994 present the consolidated results of operations as if the acquisition
had occurred on September 30, 1994. The unaudited pro forma income statement
data also reflect two additional significant fiscal 1995 transactions, the sale
of the Treasure Stawinner and the June 30, 1995 dividend and capital
distribution (both discussed in footnote 5 to Arethusa's September 30, 1995
Annual Report on Form 10-K), as if each had occurred on September 30, 1994. Such
unaudited pro forma financial data may
 
                                        7
<PAGE>   8
 
not be indicative of the results of operations of Arethusa had the transactions
been completed on such earlier date, nor is it necessarily indicative of future
financial results.

</TABLE>
 
     The historical operating results for the Arethusa Yatzy included in the
unaudited pro forma financial data have been adjusted for (i) duplicate
administrative expenses, (ii) depreciation expense calculated based upon
Arethusa's cost and estimated useful life, (iii) a reduction in insurance
expense based upon Arethusa's lower insured value, and (iv) interest calculated
based upon Arethusa's $30.0 million note.
 
4. COMMITMENTS AND CONTINGENCIES:
 
     Operating Lease -- Arethusa is committed under a lease agreement for office
space which continues until August 30, 2002. The lease may be canceled in
December 1996 for a lump-sum payment of approximately $1,023,000.
 
     Litigation -- Arethusa is engaged in various claims and litigation arising
from operations. In the opinion of management, uninsured losses, if any,
resulting from these matters will not have a material adverse effect on
Arethusa's results of operations or financial position.
 
     Revenue Agent Reviews -- Revenue agent reviews are currently in progress
with respect to certain of Arethusa's subsidiaries and operations in Indonesia
and the United States. While Arethusa cannot predict with certainty the outcome
of such reviews, management does not believe the ultimate outcome of these
reviews will have a material adverse impact on Arethusa's consolidated financial
position or results of operations.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Board of Directors and Shareholders of
Arethusa (Off-Shore) Limited:
 
     We have audited the accompanying consolidated balance sheets of Arethusa
(Off-Shore) Limited (a Bermuda company) and subsidiaries as of September 30,
1995 and 1994, and the related consolidated statements of income, shareholders'
investment and cash flows for each of the three years in the period ended
September 30, 1995, which, as described in Note 1, have been prepared on the
basis of accounting principles generally accepted in the United States. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
     We conducted our audits in accordance with auditing standards generally
accepted in the United States. United States standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Arethusa (Off-Shore) Limited
and subsidiaries as of September 30, 1995 and 1994, and the results of their
operations and their cash flows for each of the three years in the period ended
September 30, 1995, in conformity with accounting principles generally accepted
in the United States.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                 ARETHUSA (OFF-SHORE) LIMITED AND SUBSIDIARIES
 
1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES:
 
  General Organization
 
     Arethusa (Off-Shore) Limited (herein referred to as Arethusa or the
Company) is a Bermuda corporation, incorporated on August 31, 1990. Arethusa was
formed for the purpose of acquiring offshore drilling rigs and certain other
property and equipment owned by Zapata Off-Shore Company and its subsidiaries
(Zapata or ZOS), and on October 31, 1990, these assets were purchased for $298
million.
 
     In June 1993, the Company effected a two-for-three reverse stock split and
reduced the par value of its stock from $10 to $.10 per share. In connection
with the reverse stock split, the shareholders authorized additional shares of
common stock, resulting in a total of 50,000,000 shares authorized. In August
1993, Arethusa completed an Initial Public Offering (IPO) of 4,896,000 shares of
common stock at an initial price to the public of $10 per share, of which
4,000,000 shares were sold by the Company and 896,000 shares were sold by a
shareholder. These shares are publicly traded on the NASDAQ National Market
System.
 
  Consolidation
 
     The consolidated financial statements are prepared in accordance with
accounting principles generally accepted in the United States, expressed in
United States dollars and include the accounts of the Company and its wholly
owned subsidiaries. All significant intercompany accounts and transactions have
been eliminated in consolidation.
 
  Equity Securities
 
     As of September 30, 1995, the Company had investments in equity securities.
In accordance with Statement of Financial Accounting Standards (SFAS) No. 115,
"Accounting for Certain Investments in Debt and Equity Securities", such equity
securities are reflected in the accompanying balance sheet as available-for-sale
securities at the quoted market value as of September 30, 1995. Unrealized gains
on the investment are reported as a separate component of shareholders'
investment, until realized. The quoted market value of the shares held by the
Company may not be the value that would be realized should the Company dispose
of all of the shares in a short period of time.
 
  Supplies and Spare Parts
 
     Supplies and spare parts are stated at average cost which does not exceed
market value.
 
  Mobile Drilling Rigs and Equipment
 
     Mobile drilling rigs and equipment are recorded at cost. Depreciation is
provided on the straight-line method without salvage value, using an estimated
useful life, as follows:

                                                                               USEFUL LIFE
                                                                               -----------
    <S>                                                                        <C>
    Mobile drilling rigs.....................................................     25 years
    Drill pipe and other drilling equipment..................................    4-6 years
    Furniture, fixtures, automobiles and other...............................   3-25 years
</TABLE>
 
     For mobile drilling rigs acquired, the estimated useful life is based upon
when the asset was placed in service by its original owner but will not be less
than five years.
 
     Routine repairs and maintenance are charged to expense as incurred. Repair
and maintenance expense totaled approximately $16,400,000, $14,500,000 and
$10,100,000 for fiscal years 1995, 1994 and 1993, respectively. Major renewals
and improvements are capitalized and are generally depreciated over five years.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
          ARETHUSA (OFF-SHORE) LIMITED AND SUBSIDIARIES -- (CONTINUED)
 
Upon disposal of assets subject to depreciation, the accounts are relieved of
related costs and accumulated depreciation.
 
  Mobilization Costs
 
     When significant costs are incurred in connection with mobilizing a
drilling rig for a new contract, such costs, net of any mobilization fees
received, are deferred and amortized over the new contract term. When a rig is
mobilized before obtaining a new contract, the market in the new locale is
analyzed and the projected return on the mobilization investment is determined,
and mobilization costs are deferred and amortized over a period not to exceed 24
months. Mobilization costs incurred in connection with rig purchases are
capitalized as part of the purchase price and are depreciated over the life of
the rig.
 
  Interest Rate Swap Agreements
 
     From time to time, the Company has entered into interest rate swap
agreements whereby the Company has exchanged the floating interest rate under
certain debt agreements for a fixed interest rate. The differential paid or
received is accrued as interest rates change and recognized over the life of the
agreements. No such financial instruments have been in effect since October
1993.
 
  Revenue Recognition
 
     Contract drilling revenues are recognized as earned, based on contractual
drilling rates. Losses are recognized in the period in which the loss is
identified.
 
  Foreign Currency Translation
 
     Arethusa accounts for foreign currency translation in accordance with SFAS
No. 52, "Foreign Currency Translation." In connection therewith, the United
States dollar was determined to be the functional currency as revenues are
received and operating costs are paid primarily in United States dollars.
 
  Earnings (Loss) per Share Data
 
     Earnings (loss) per share data is based on the weighted average number of
common shares and common equivalent shares outstanding during each year, if
dilutive.
 
  Fair Value of Financial Instruments
 
     In December 1991, the Financial Accounting Standards Board issued SFAS No.
107, "Disclosures about Fair Value of Financial Instruments." The Company
believes that the fair value of its financial instruments approximates their
book value. This determination was made as follows:
 
          Long-Term Debt. The fair value of the Company's long-term debt, all of
     which is floating rate, is estimated based on rates currently available to
     the Company for debt with similar maturities.
 
          Currency Exchange Contracts. Currency exchange contracts in place on
     September 30, 1993, expired between October 1993 and December 1993. As
     market value gains and losses on currency exchange contracts are recognized
     as an offset to currency exchange losses in the statements of income
     (discussed in Note 8) in the period in which they occur, the carrying value
     is therefore equal to the fair value. At September 30, 1995 and 1994, no
     currency exchange contracts were outstanding.
 
  Recent Accounting Pronouncement

option or similar equity instrument and is effective for fiscal years beginning
after December 15, 1995. As allowed by SFAS No. 123, the Company plans to
continue to measure compensation cost for their compensation plans using the
intrinsic value based method of accounting prescribed by Accounting Principles

disclosure in the future of the difference, if any, between compensation cost
included in net income and the related cost measured under the fair value
method.
 
2. RELATED-PARTY TRANSACTIONS:
 
  Sale of 50-Percent Interest in Arethusa Heritage
 
     On December 31, 1991, a subsidiary of Ymer Offshore AB (Ymer), a former
shareholder of Arethusa, purchased a 50-percent interest in the Arethusa
Heritage, for an aggregate purchase price of $10 million. The purchase price was
paid $2 million in cash and the remaining $8 million in the form of a secured
note.
 
     As a part of this sale, Ymer and Arethusa also entered into option
agreements in which Ymer had the right to sell back to Arethusa, and Arethusa
had the right to repurchase, the Ymer interest in the rig at specified prices.
Effective January 31, 1994, the Company repurchased this 50 percent interest in
the Arethusa Heritage for $8.4 million. As payment for the repurchase, the
Company paid $400,000 in cash and accepted cancellation of the $8.0 million
promissory note which was due on January 31, 1994. The Company now owns 100% of
the Arethusa Heritage.
 
     As a result of these option agreements, Arethusa did not recognize this
transaction as a sale. The Company recorded a deferred credit for the amount of
the gain which was amortized based upon the approximate period of time the
options were expected to be outstanding. For the years ended September 30, 1994
and 1993, respectively, Arethusa recognized $49,100 and $884,300 of gain, and
$142,700 and $435,900 of interest income related to this transaction.
 
     During fiscal years 1994 and 1993 Arethusa operated the Arethusa Heritage
under a bareboat charter agreement. The charter fee totaled $357,300 and
$1,076,100, respectively, during the years ended September 30, 1994 and 1993.
This bareboat charter agreement terminated on January 31, 1994, in connection
with Arethusa's repurchase of the 50-percent interest in the rig.
 
  Yatzy Management and Operating Services Agreement
 
     Prior to Arethusa's acquisition of the Yatzy in May 1995 (see Note 4), the
rig was managed by Arethusa under a management and operating services agreement
with Exmar, N.V. (a Belgium corporation which is related to Alphee S.A., a
principal shareholder of the Company). Under the terms of the agreement,
Arethusa was paid a management fee, and all operating expenses were paid by
Exmar, N.V. This management fee totaled $374,500, $638,700 and $638,700 for
fiscal 1995, 1994 and 1993 respectively, and the Company has recorded such fees
as a reduction of Arethusa's administrative expenses.
 
  Other Related-Party Transactions
 
     The Company previously provided $710,000 in financing for the homes of the
president and a vice president of Arethusa Off-Shore Company (AOC), a wholly
owned subsidiary of Arethusa, who were recruited from outside the United States.
These notes, which originally bore interest at 9 percent per annum, matured
during fiscal 1994 and were renewed for additional three year terms. During
fiscal year 1995, AOC agreed to take possession of the home of the vice
president in full payment of his note. The remaining note receivable from the
president is now payable in full in 1997, with interest due quarterly in arrears
based upon the stated rate of 8.12 percent per annum. This note receivable is
secured by a real estate lien note and the deed of trust for the home.

     Ymer and International Maritime Investors S.A. (IMI), the majority
shareholder of Alphee S.A., each guaranteed $4.5 million of the rig secured debt
due August 20, 1996. The Company agreed to compensate Ymer and IMI at the rate
of 1 1/2 percent per annum of the guaranteed amount. Such guarantees expired
with the debt repayment in December 1994.
 
3. CASH FLOW INFORMATION:
 
     For purposes of the statements of cash flows, all investments with an
original maturity of three months or less are considered to be cash equivalents.
Net cash used in operating activities reflects cash interest payments of
approximately $7,109,000, $6,139,000 and $11,209,000; and income and withholding
tax payments of approximately $1,389,000, $1,744,000 and $1,852,000 for fiscal
years 1995, 1994 and 1993, respectively.
 
     Restricted cash is comprised of balances maintained to guarantee the
Company's performance under drilling contracts in Indonesia and India, and rig
availability for certain drilling contract bids.
 
4. ASSET ACQUISITIONS:
 
  Acquisition of the Arethusa Yatzy
 
     On May 3, 1995, the Company acquired the Arethusa Yatzy (formerly the
Yatzy), a dynamically-positioned semisubmersible drilling rig built in 1989. The
rig has been managed by Arethusa since 1991 and in May 1995 began a drilling
contract with Petroleos Brasileiros, S.A. (Petrobras), which is expected to keep
the unit working offshore Brazil through November 1998. The purchase price was
$50.2 million, $20.2 million of which was paid from existing cash balances and
$30.0 million of which was funded through a new eight-year, rig-secured loan.
 
     The following unaudited pro forma income statement data for the years ended
September 30, 1995 and 1994, present the consolidated results of operations as
if the acquisition had occurred at the beginning of the fiscal year 1994. The
unaudited pro forma income statement data also reflect two additional
significant fiscal 1995 transactions, the sale of the Treasure Stawinner
discussed in Note 5 and the June 30, 1995, dividend and capital distribution of
$61.0 million ($3.00 per share), as if each had occurred at the beginning of
fiscal 1994. Since the gain on the sale of the Treasure Stawinner is a
nonrecurring credit, this gain has not been included in this pro forma income
statement data. If calculated as if the sale occurred at the beginning of fiscal
1994, this gain amount would approximate $24.4 million. Such unaudited pro forma
financial data may not be indicative of the results of operations of the Company
had the transactions been completed on such earlier date, nor is it necessarily
indicative of future financial results.

  Acquisition of Arethusa Worker and Treasure Stawinner.
 
     On August 20, 1993, Arethusa acquired two deepwater semisubmersible
drilling rigs, the Arethusa Worker and the Treasure Stawinner, for $59.0 million
in cash and 1,000,000 shares of common stock of the Company. Arethusa funded the
cash portion of this acquisition with $34.0 million of cash proceeds from the
IPO and $25.0 million of bank debt.
 
5. ASSET DISPOSITIONS:
 
  Sale of the Treasure Stawinner
 
     On June 30, 1995, Arethusa completed the Sale of the Treasure Stawinner for
conversion to a floating production unit for Petrobras. Arethusa received $55.0
million in cash and has retained ownership of certain drilling equipment, which
was removed from the rig and will be used by the Company for other purposes.
Upon closing of the transaction, the Company recognized a gain of approximately
$27.9 million, repaid $12.6 million of secured debt, and declared a $3 per share
dividend and capital distribution to shareholders. The dividend/distribution
totaled $61.0 million, and was paid on July 28, 1995 to shareholders of record
as of July 14, 1995.
 
  Sale of Miss Kitty
 
     In July 1993, Arethusa sold the jackup Miss Kitty for $22.0 million in
cash. Arethusa continues to operate the Miss Kitty pursuant to a bareboat
charter agreement with the new owners which has recently been extended for an
additional year through July 30, 1997. The Company realized a gain of $3.6
million which is being amortized ratably over the initial three-year charter
term. The charter provides for a fixed charter fee of $9,765 per day for the
first eighteen months, and thereafter a basic charter rate of $6,750 per day
plus a revenue sharing component. The Company used $18.2 million of the proceeds
to reduce outstanding debt.
 
  Sale of Zapata Arctic
 
     Effective March 30, 1992, Arethusa sold the Petrobras XXV (formerly the
Zapata Arctic) to an affiliate of Petrobras, effected through a sales-type lease
with a term of 10 years, for a gain of approximately $27.3 million. The lease
stipulated a down payment of $2,642,500 and 40 quarterly installments, for total
principal payments of $75,500,000 plus interest. The interest component of the
installment was adjusted quarterly to the three-month London Interbank Market
Rate plus 4 percent. At September 30, 1994 and 1993, this rate was 9.31 and 7.19
percent per annum, respectively.
 
     The lessee had two options to purchase the rig for the then unpaid
principal balance of the lease, in March 1995 or December 1997. On March 31,
1995 Petrobras exercised their purchase option under the lease of the Petrobras
XXV. The Company transferred title of this rig to the Petrobras affiliate and
received lease proceeds of $54.4 million in cash, which were used to pay $17.9
million of secured debt and $1.2 million in commissions.
 
  Sale of Bonito II
 
     Arethusa sold the Bonito II on December 31, 1991, for a gain of
approximately $5.1 million. The buyer paid $25.3 million in cash for the rig and
services provided by Arethusa in connection with the sale. Arethusa continues to
operate the Bonito II pursuant to a bareboat charter agreement which currently
extends to August 1996. The charter rate is currently $7,550 per day plus a
revenue sharing component. The Company has the option to extend the charter for
two additional one-year periods from August 1996.
 
     During March 1994, the Bonito II ended its contract in India and was
mobilized to the Gulf of Mexico where it commenced operations under a drilling
contract in July 1994. In connection with this mobilization,

  Rig-Secured Debt Due May 3, 2003
 
     In connection with the acquisition of the Arethusa Yatzy on May 3, 1995,
the Company entered into a credit agreement to borrow $30.0 million from its
lending banks. Under the terms of the agreement, principal is payable in sixteen
semi-annual installments of $1.9 million. Interest rates are based upon an
average of the Reuters FRBD reference rates plus 1 1/2 percent per annum, and
payable in arrears. The effective interest rate for fiscal year 1995 was 7.54
percent.
 
     The loan is secured by a first mortgage on the Arethusa Yatzy. Loan
covenants included, among other financial provisions, (a) maintenance of minimum
collateral values, (b) restrictions on the sale of collateralized assets, (c)
restrictions on declarations of dividends and (d) limitations on further
indebtedness.
 
  Rig-Secured Debt Due December 22, 1999
 
     On December 20, 1994, the Company entered into a new credit agreement with
its lending banks. Under this agreement, certain wholly-owned subsidiaries of
the Company borrowed $80 million to refinance then existing rig-secured debt.
During fiscal 1995 this loan was paid down by $37.2 million, which included
three scheduled quarterly installments totalling $6.7 million, and two
additional payments totalling $30.5 million made in connection with the
monetization of the Petrobras XXV lease and the Sale of the Treasure Stawinner
(see Note 5). Currently, quarterly payments on this loan total $1.7 million with
a final payment of $15.4 million due in December 1999. Interest is payable
quarterly in arrears and is based upon the London Interbank Market Rate plus
1 1/2 percent per annum. The effective interest rate for fiscal year 1995 was
7.97 percent.
 
     The loan is secured by the first priority fleet mortgage on all rigs owned
by the Company other than the Arethusa Yatzy. Other loan covenants are similar
to those in the rig-secured debt due May 3, 2003.

7. TAXES:
 
     Arethusa's United States subsidiaries and Bermuda subsidiaries with
operations in United States territorial waters provide taxes at the United
States federal statutory rate. As of September 30, 1995, these subsidiaries
collectively had United States net operating loss carryforwards of approximately
$85.6 million for United States tax reporting purposes. These losses are
available to benefit future United States tax expense and expire in fiscal years
2006 through 2010.
 
     Arethusa's subsidiaries operating in the territorial waters of countries
outside of the United States provide taxes at the rates applicable in those
countries. The tax provision includes income and withholding taxes applicable to
operations in India, Indonesia, Brazil and the Netherlands.
 
     At the present time, no income, profit, capital or capital gain taxes are
levied in Bermuda and, accordingly, no provision for such taxes has been
recorded by the Company. In the event that such taxes are levied, the Company
has received an undertaking from Bermuda Government exempting it from all such
taxes until March 28, 2016.
 
     Revenue agent reviews are currently in progress with respect to certain of
the Company's subsidiaries and operations in Indonesia and the United States.
While the Company cannot predict with certainty the outcome of such reviews,
management does not believe the ultimate outcome of these reviews will have a
material adverse impact on the Company's consolidated financial position or
results of operations.

     Effective October 1, 1993, the Company adopted SFAS No. 109, "Accounting
for Income Taxes," which requires recognition of deferred tax liabilities and
assets for the expected future tax consequences of events that have not been
recognized in the financial statements or tax returns. Under this method,
deferred tax liabilities and assets are determined based on differences between
the financial statement carrying amounts and tax bases of assets and liabilities
using enacted tax rates and laws in effect in the years in which the differences
are expected to reverse. Prior-year financial statements were not restated for
SFAS No. 109. The adoption of SFAS No. 109 had no material effect on the
Company's consolidated financial position or results of operations.
 
     No deferred taxes were required to be provided during fiscal 1995, 1994, or
1993.
 
     The components of the net deferred tax asset (liability) as of September
30, 1995 and 1994, are as follows (in thousands):

8. CURRENCY EXCHANGE:
 
     In an effort to minimize the effects of exchange rate fluctuations, the
Company generally hedges its exposure through obtaining payment for drilling
contracts in United States Dollars. During fiscal years 1994 and 1993, the
Company also entered into currency exchange contracts to address specific risks.
The Company does not engage in currency speculation. At September 30, 1993, the
Company had contracts maturing between October and December 1993 requiring it to
purchase $3.6 million in foreign currency (the equivalent

of 119.0 million Indian rupees). During fiscal year 1994, the Company committed
to an additional $1.0 million of currency exchange contracts which matured
between December 1993 and June 1994. There were no currency exchange contracts
in place at September 30, 1995 or 1994. Market value gains and losses on the
currency exchange contracts have been recognized as an offset to currency
exchange losses in the statements of income. Total currency exchange losses
recorded in the statements of income were approximately $1.2 million, $1.2
million and $1.8 million for fiscal years 1995, 1994 and 1993, respectively.
These losses primarily resulted from operations in Brazil and India.
 
9. MAJOR CUSTOMERS AND CONCENTRATION OF CREDIT RISKS:
 
     Arethusa's customer base includes major and independent oil and gas
companies and government owned oil companies. During fiscal 1995, 1994 and 1993,
the Company earned 52.1 percent, 54.3 percent, and 49.1 percent, respectively,
of its revenues from major customers. A summary of the major customers for these
years were as follows: year ended September 30, 1995 -- Petrobras and Shell Oil
Company, 27.8 percent and 24.3 percent, respectively; year ended September 30,
1994 -- Petrobras, Marathon Oil Company, and Maxus Southeast Sumatra, Inc., 26.3
percent, 15.0 percent and 13.0 percent, respectively; year ended September 30,
1993 -- Indian Oil & Natural Gas Commission, Maxus Southeast Sumatra, Inc. and
Petrobras, 17.4 percent, 15.8 percent and 15.9 percent, respectively.
 
10. COMMITMENTS AND CONTINGENCIES:
 
  Operating Lease
 
     Arethusa is committed under a lease agreement for office space which
continues until August 30, 2002. The lease may be canceled in December 1996 for
a lump-sum payment of approximately $1,023,000. Under the terms of the lease,
the Company only made cash payments to reimburse the landlord for operating
expenses through December 31, 1993. The Company began making additional payments
for base, rental installments on January 1, 1994. Rental charges are expensed on
a straight-line basis over the term of the lease. The Company recognized rental
expense of approximately $566,000, $552,000 and $524,000 of which approximately
$203,000, $211,000 and $183,000 were paid as operating expenses in fiscal years
1995, 1994 and 1993, respectively. Estimated future minimum lease payments,
excluding reimbursable operating expenses, under this operating lease are as

11. BENEFIT PLANS:
 
  Pension Plan
 
     AOC established a defined benefit pension plan effective October 1, 1992,
which covers substantially all U. S. citizens and U. S. permanent residents who
are employed by AOC. Employees are automatically enrolled in the plan following
the completion of one year of service and are 100 percent vested after five
years of service. Benefits are calculated and paid based on employees' years of
credited service and average final compensation using an excess benefit formula
integrated with social security covered compensation.
 
     Pension costs are determined actuarially and funded to the extent allowable
under the Internal Revenue Code. The plan's assets are invested in cash and cash
equivalents, equity securities, government and corporate debt securities.
 
     The significant actuarial assumptions as of the plan's year-end are set
forth in the following table:

  Profit-Sharing Plan
 
     AOC established a defined contribution profit-sharing plan effective
October 1, 1992 which covers substantially all U.S. citizens, U.S. permanent
residents and third country national expatriates who are employed by AOC. The
plan and trust agreement are intended to meet the requirements of Section 401(a)
and all related sections of the Internal Revenue Code.
 
     Employees may enroll in the plan following the completion of one year of
service. Participants may elect to make contributions from 1 percent up to 16
percent of gross monthly salary to the plan: a maximum of 10 percent on a 401(k)
basis; a maximum of 16 percent on a 401(m) basis. All amounts contributed to the
plan are deposited in a trust with a national bank and administered by
independent trustees.
 
     At the end of the plan year on September 30, the Company will match a
minimum of 10 percent up to a maximum of 100 percent of eligible basic
contributions made by participants during the plan year. The basic rate of
contribution used to determine the Company matching amount is 6 percent, on a
401(k) or 401(m) basis. The actual matching percentage is determined by the
Company's Board of Directors at the end of the plan year. AOC made
profit-sharing provisions of approximately $276,000, $134,000 and $120,000 for
1995, 1994 and 1993, respectively.
 
  Employee Stock Option Plan
 
     In August 1993, the Company adopted the Arethusa (Off-Shore) Limited 1993
Employee Stock Option Plan (the Employee Plan) pursuant to which a maximum
aggregate of 666,667 shares of Common Stock are available for grant to eligible
employees. Options granted pursuant to the Employee Plan vest in equal
installments over three years and remain exercisable for a period of seven
years, so long as the option holder remains an employee of the Company as of the
date of exercise. The exercise price of options granted under the Employee Plan
equal the market price of the Common Stock on the date of grant. The Employee
Plan provides for the adjustment of the number of shares awarded thereunder, and
the exercise price thereof, on any stock dividend, any subdivision or
combination of the outstanding shares of Common Stock and any merger,
consolidation, recapitalization of the Company or similar event which affects
the issued and outstanding shares of Common Stock.
 
     In August 1993, the Company granted 466,666 options at an option price of
$10 per share, the market price in the IPO. Accordingly, no compensation expense
has been recorded with respect to these options.
 
     As of September 30, 1995 there were 308,000 exercisable options, and 4,667
options had been canceled and surrendered. No options have been exercised.
 
     In September 1995 the board of directors approved a $3 per share reduction
in the option price to $7 per share, subject to shareholder approval at the next
annual general meeting. This action was proposed as a result of the $3 per share
dividend and capital distribution paid by the Company in July 1995.
 
  Non-employee Director Stock Option Plan
 
     In February 1995, the Company's shareholders approved the Arethusa
(Off-Shore) Limited 1994 Nonqualified Stock Option Plan for Non-Employee
Directors ("Directors' Plan"), pursuant to which a maximum aggregate of 250,000
shares of common stock were authorized. Under the Directors' Plan eligible
directors were granted an option to purchase 20,000 shares of the Company's
common stock, at an exercise price equal to the fair market value of the common
stock on the date of grant. Options granted under this plan vest in equal annual
installments over a three-year period, and expire seven years from date of
grant.
 
     As of September 30, 1995, 160,000 options had been granted under the
Directors' Plan; 100,000 of these options carry an option price of $11.25 based
upon a May 1994 date of grant, and the remaining 60,000 options

14. EVENT (UNAUDITED) SUBSEQUENT TO DATE OF REPORT OF INDEPENDENT PUBLIC
    ACCOUNTANTS:
 
     On December 7, 1995, Arethusa entered into a letter of intent with Diamond
Offshore Drilling, Inc. ("Diamond Offshore") for the merger of the two
companies. The terms of the proposed transaction provide that, upon satisfaction
of certain conditions precedent, including execution of definitive agreements
(which execution occurred February 9, 1996) and obtaining approval from Arethusa
and Diamond Offshore shareholders and certain regulatory agencies, each of the
issued and outstanding shares of Arethusa common stock would be converted into
the right to receive .88 shares of Diamond Offshore common stock. On

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
          ARETHUSA (OFF-SHORE) LIMITED AND SUBSIDIARIES -- (CONTINUED)
 
February 9, 1996, Arethusa declared a cash dividend of $.25 per share to the
holders of its common stock. Management anticipates the merger will be
consummated no later than July 31, 1996.
 
     Upon successful consummation of the merger, options awarded to certain
officers, directors and employees of Arethusa will become fully vested and
exercisable. Additionally, AOC has entered into executive severance agreements
with certain executive officers and has amended its severance policy for most
shore based employees which will provide payment of certain additional benefits
to the employees if they are terminated following the merger.
 
     Additionally, subject to approval by Arethusa shareholders and to a
successful merger, the exercise price of options granted under the 1993 Employee
Stock Option Plan (approximately 462,000 shares granted) would be reduced by $3
per share. In the event the option exercise price is reduced to $7 per share,
Arethusa would be required to record compensation expense in its financial
statements for the difference between the revised exercise price of $7 per share
and the market value on the date approval is received from shareholders. To the
extent the market value of Arethusa shares continues to increase above the
exercise price there will be an increased charge to compensation expense.

        UNAUDITED PRO FORMA CONSOLIDATED CONDENSED FINANCIAL STATEMENTS
 
     The unaudited pro forma consolidated condensed financial statements as of
and for the three months ended March 31, 1996 have been prepared based on the
historical financial statements of Diamond Offshore and Arethusa as of and for
the three months ended March 31, 1996. Such historical financial statements are
unaudited but, in the opinion of management, include all adjustments necessary,
consisting only of normal recurring accruals. The unaudited pro forma
consolidated condensed income statement for the year ended December 31, 1995 has
been prepared based on the historical financial statements of Diamond Offshore
as of and for the year ended December 31, 1995 and based on pro forma income
statement data for Arethusa that reflect adjustments to Arethusa's historical
consolidated income statement for the year ended September 30, 1995 in
connection with (i) the acquisition of the Arethusa Yatzy, (ii) the sale of the
Treasure Stawinner and (iii) the dividend and capital distribution of $61.0
million ($3.00 per share of Arethusa Common Stock) as if each had occurred at
the beginning of fiscal year 1995. The pro forma income statement for the three
months ended March 31, 1996 gives effect to the Acquisition. The pro forma
income statement for the year ended December 31, 1995 gives effect to (i) the
Acquisition, (ii) the initial public offering of Diamond Offshore Common Stock
in October 1995 (the "Diamond Offshore Initial Public Offering") and, in
connection therewith, the use of the proceeds to repay all of Diamond Offshore's
then outstanding indebtedness to Loews Corporation, a Delaware corporation
("Loews"), and to fund the payment of a special dividend to Loews and (iii)
interest expense for working capital borrowings, and commitment and other fees,
under Diamond Offshore's $150.0 million credit facility with a group of banks
(the "Diamond Offshore Bank Credit Facility"). The Acquisition was accounted for
under the purchase method of accounting using a purchase price of $560.7
million, which was calculated based on a seven-day average of the closing price
of Diamond Offshore Common Stock at the time the Acquisition was announced. The
pro forma consolidated condensed balance sheet was prepared assuming such
transactions were consummated on March 31, 1996 and give effect to events
directly attributable to the transactions, including those that are
nonrecurring. The pro forma consolidated condensed income statement was prepared
assuming the transactions were consummated as of the beginning of the period
presented and give effect to events directly attributable to the transactions
which are expected to have a continuing impact on the combined entity. These pro
forma consolidated condensed financial statements should be read in conjunction
with the other financial information of Arethusa presented elsewhere in this
Current Report on Form 8-K and of Diamond Offshore filed with the Securities and
Exchange Commission. The pro forma consolidated condensed financial statements
are presented for illustrative purposes only and are not necessarily indicative
of actual results that would have been achieved had the transactions been
consummated on such dates, and are not necessarily indicative of future results.
The allocation of the purchase price is preliminary, as valuation and other
studies have not been finalized. It is not expected that the final allocation of
the purchase price will produce materially different results from those
presented herein.

    (1) Under the Plan of Acquisition (as amended), from and after the
        Effective Time, Diamond Offshore and Arethusa and their respective
        subsidiaries will honor in accordance with their terms certain Arethusa
        employment, severance, consulting and salary continuation plans.
 
    (2) Arethusa has agreed to pay Merrill Lynch, Pierce, Fenner & Smith
        Incorporated a fee of $7.5 million for financial advisory services in
        connection with the Acquisition upon the closing of the Acquisition.
 
    (3) Adjustment for legal, accounting, printing and other nonrecurring
        charges expected to be incurred in connection with the Acquisition.
 
    (4) Arethusa is committed under a lease agreement for office space that
        continues until August 30, 2002. The lease may be canceled in December
        1996 for a lump-sum payment of approximately $1.0 million. Such payment
        has no future economic benefit to the combined company and is
        incremental to other costs incurred by either Arethusa or Diamond
        Offshore in the conduct of activities prior to the Effective Time.
 
(c)  Adjustment for fair values, based on current appraisals, of the eight
     semisubmersible drilling rigs, three jack-up drilling rigs, and other
     property and equipment owned by Arethusa.
 
(d)  Adjustment for fair values of identifiable assets and for the excess of the
     cost of Arethusa over the sum of the amounts assigned to identifiable
     assets acquired less liabilities assumed.
 
(e)  Adjustment for the estimated unfunded termination liability related to the
     Arethusa defined benefit plan.
 
(f)  Adjustment for fair values of liabilities assumed and for the deferred tax
     liability for estimated future tax effects of differences between the tax
     bases and the fair value amounts assigned to identifiable assets and
     liabilities of Arethusa, offset by net operating loss carryforwards of
     Arethusa of approximately $30.0 million. As a result of the Acquisition,
     Diamond Offshore will have available to it certain Arethusa net operating
     loss carryforwards to reduce future U.S. federal income taxes payable. Due
     to the change in ownership of Arethusa resulting from the Acquisition,
     there will be annual limitations on the amount of Arethusa tax
     carryforwards available to be utilized by Diamond Offshore.
 
(g)  The pro forma financial statements reflect the purchase of 100% of the
     outstanding shares of Arethusa Common Stock for a total consideration of
     $560.7 million which is comprised of the following:

       (1) The value of the Diamond Offshore Common Stock to be issued in the
           Acquisition is calculated based on a seven-day average of the closing
           price of Diamond Offshore Common Stock at the time the Acquisition
           was announced (December 7, 1995) of $30.14.
 
       (2) Amount represents the fair value of the Arethusa stock options
           assumed by Diamond Offshore pursuant to the Amalgamation Agreement.
           The fair value is based on a seven-day average of the closing price
           of Diamond Offshore Common Stock at the time the Acquisition was
           announced (December 7, 1995), the Amalgamation Ratio and the option
           exercise price including the $3.00 reduction, which was approved by
           Arethusa shareholders at Arethusa's annual general meeting of
           shareholders on April 29, 1996.

    (1) The historical financial information of the Yatzy operations for the
        period from October 1, 1994, through May 2, 1995 is based upon Arethusa
        records, as manager of the rig. The previous owner of the rig prepared
        financial information only on a semi-annual, calendar year basis; and
        was unable to provide the complete financial information for the twelve
        months ended September 30, 1995. Financial statement captions for which
        Yatzy historical information is not presented (historical depreciation
        and interest expense) would have been adjusted to reflect Arethusa's
        cost basis in the Arethusa Yatzy and Arethusa's financing of the rig.
        Pro forma Yatzy acquisition adjustments (3) and (4) discussed below
        provide fully for depreciation using Arethusa's cost basis in the
        Arethusa Yatzy and interest based on Arethusa's financing of the rig.
        Additionally, it is management's understanding that there are no other
        significant transactions or activities related to the historical
        operations of Yatzy which would have a material impact on the
        as-adjusted pro forma income statement. Therefore, management believes
        the resulting pro forma income statement is in compliance with Article
        11 of Regulation S-X.
 
    (2) To reclassify and eliminate the management fee paid to Arethusa from
        direct costs to general and administrative expenses.
 
    (3) To reflect depreciation expense calculated based upon Arethusa's cost
        and estimated useful life of 25 years, which is consistent with
        Arethusa's previously established depreciation policy.
 
    (4) To adjust for additional interest expense associated with Arethusa's
        $30.0 million note entered into in connection with the acquisition of
        the Arethusa Yatzy.
 
    (5) To adjust for a reduction in insurance expense resulting from
        Arethusa's lower insured value for the Arethusa Yatzy.
 
    (6) To reflect the elimination of historical operations, interest expense
        and gain on sale of assets for the Treasure Stawinner.
 
    (7) To reflect the reduction in interest income resulting from the dividend
        and capital distribution made to shareholders in fiscal 1995.
 
(b)  To record the additional depreciation expense and amortization of goodwill
     resulting from the allocation of the purchase price. The pro forma
     adjustment assumes an 18-year average estimated useful life for
     depreciation and a 20-year amortization period for goodwill.
 
(c)  To adjust interest expense, assuming that the Diamond Offshore Initial
     Public Offering and repayment of indebtedness occurred on January 1, 1995.
 
(d)  To record income tax expense on the effect of the pro forma adjustments to
     depreciation and amortization and interest expense.
 
(e)  Weighted average shares outstanding as if both the October 1995 issuance of
     15.0 million shares by Diamond Offshore through the Diamond Offshore
     Initial Public Offering and the 17.9 million shares to be issued by Diamond
     Offshore in consideration of the Arethusa Common Stock had taken place on
     January 1, 1995.
 
(f)  After the Diamond Offshore Initial Public Offering, Diamond Offshore had
     50.0 million shares of Diamond Offshore Common Stock outstanding. Assuming
     the Diamond Offshore Initial Public Offering had occurred at January 1,
     1995, Diamond Offshore would have recognized net income of $10.0 million,
     or $0.20 per share of Diamond Offshore Common Stock, after adjusting for
     the after-tax effects of a reduction in interest expense.
