ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS
 
  On December 19, 1996, Offshore Logistics, Inc. ("OLOG") acquired 49% of the
common stock and a significant economic interest in Bristow Aviation Holdings
Limited ("Bristow"). Bristow is incorporated in England and holds all of the
outstanding shares in Bristow Helicopter Group Limited ("BHGL").
 
  Bristow was organized with three different classes of ordinary shares
(common stock) having disproportionate voting rights. Caledonia Investments
plc and its subsidiary, Caledonia Industrial & Services Limited,
(collectively, "Caledonia"), OLOG and Mr. Andreas K.L. Ugland of Oslo, Norway
(the "E.U. Investor"), a business affiliate of Bristow in a Norwegian
helicopter services company, own 49%, 49% and 2% respectively, of Bristow's
total outstanding ordinary shares, representing 37.5%, 37.5% and 25%,
respectively, of the total voting rights.
 
  OLOG, Caledonia, the EU Investor and Bristow entered into a shareholders'
agreement respecting, among other things, the composition of the board of
directors of Bristow. Under such agreement, Caledonia has the right to appoint
three directors, OLOG has the right to appoint two directors, the EU Investor
is appointed a director and the seventh director is appointed from Bristow's
management. On all matters coming before Bristow's board, Caledonia's
appointees has a total of five votes and the four other directors have one
vote each.
 
  These ownership and voting arrangements allow Bristow to satisfy The British
Civil Aviation Authority (the "CAA") requirements that qualified European
shareholders have majority ownership and control.
 
  OLOG paid (Pounds)80.2 million (approximately $132 million) in cash (funded
from existing OLOG cash balances and the proceeds of 6% Convertible
Subordinated Notes ("Notes") due 2003 and issued on December 17, 1996), $7.5
million of the Notes issued to Caledonia and 1,374,389 shares of Common Stock
issued to Caledonia and BHGL's management on December 19, 1996. In addition,
OLOG acquired (Pounds)5 million principal amount of BHGL's subordinated debt
for cash of approximately $8.9 million including accrued interest. Caledonia
received 1,300,000 shares of the Common Stock and BHGL's management received
74,389. OLOG provided Caledonia and BHGL's management with certain customary
registration rights under U.S. securities laws respecting the resale of their
shares of Common Stock (including the shares underlying the Notes issued to
Caledonia).
 
 
  In addition to its ownership of 49% of Bristow's outstanding ordinary shares
and (Pounds)5.0 million principal amount of Bristow's subordinated debt, OLOG
acquired (Pounds)91 million (approximately $150 million) principal amount of
subordinated unsecured loan stock (debt) of Bristow bearing interest at an
annual rate of 13.5% and payable semi-annually. Bristow has the right to defer
payment of interest on such debt until January 31, 2002. Any such deferred
interest would also accrue interest at an annual rate of 13.5%.
 
 
  So long as Caledonia has a significant interest in the shares of Common
Stock issued to it pursuant to the Master Agreement or maintains its voting
control of Bristow, Caledonia will have the right to nominate two persons to
the board of directors of OLOG and to replace any such directors so nominated.
Initially, Caledonia has nominated Peter N. Buckley, its Chairman, and
Jonathan H. Cartwright, Caledonia's Finance Director, to the OLOG board.
 
  Caledonia, OLOG and the EU Investor also entered into a put/call agreement
whereunder, upon giving specified prior notice, OLOG has the right to buy all
the Bristow shares held by Caledonia and the EU Investor, who, in turn, each
has the right to sell such shares to OLOG. Under current U.K. law, OLOG would
be required to find a qualified European investor to own any Bristow shares it
acquired under the put/call agreement. The agreement fixes the put/call price
of the shares at (Pounds)5.1 million (including (Pounds)4.9 million for
Caledonia's shares and (Pounds)0.2 million for the EU Investor's shares), plus
an additional amount equal to a compound annual return of 10% should either
Caledonia or the EU Investor elect to sell its shares to OLOG or 12% should
OLOG elect to buy such shares. OLOG has secured the fixed price of Caledonia's
Bristow shares with U.K. government securities and guarantee to Caledonia the
appropriate compound annual return thereon.
 
  OLOG will consolidate Bristow's results for financial reporting purposes.
The economic interests of Caledonia and the EU Investor in Bristow will be
limited, in effect, to the fixed put/call price for their respective shares
plus a compound annual return.
 
                                       1

  Caledonia will receive management fees from Bristow for as long as Caledonia
owns its Bristow shares. Such management fees will be payable semiannually in
advance and will total (Pounds)500,000 for the first year, (Pounds)900,000 for
each of the second and third years and (Pounds)757,000 for each of the fourth
and fifth years. If OLOG exercises its right to buy Caledonia's Bristow shares
within the first five years following closing, then the full amount of the
management fees for the remainder of the five-year period will be payable to
Caledonia in a lump sum at the time of the purchase. If Caledonia exercises
its right to sell its Bristow shares to OLOG, then no management fees would be
payable after completion of the sale, unless (i) OLOG fails to purchase the
shares, (ii) Caledonia exercised its right to sell following a sale by OLOG of
its Bristow shares or (iii) OLOG is in breach of its obligations under the
shareholders' agreement. If, at the end of five years from closing, neither
the right to buy nor the right to sell has been exercised, then the management
fees payable for each of the following two years will equal (Pounds)500,000.
The EU Investor may also receive nominal management fees from Bristow as long
as he owns Bristow shares.

  2(l) Master Agreement dated December 12, 1996. The documents listed as
       "Annexures" in the Table of Contents of the Master Agreement are not
       included. The Registrant agrees to furnish supplementally a copy of
       any omitted Annexure to the Securitites and Exchange Commission upon

ITEM 9. SALES OF EQUITY SECURITIES PURSUANT TO REGULATION S.
 
  On December 19, 1996, the Registrant issued $7.5 million of the Convertible
Subordinated Notes due 2003 (the "Notes") to Caledonia in accordance with the
Bristow transaction discussed in Item 2 of this Form 8-K. The Notes are
convertible into common stock at any time on or after February 15, 1997, and
prior to the close of business on December 15, 2003, at a conversion price of
$22.86 per share, subject to adjustment in certain events. On such date, the
Registrant also issued 1,374,389 shares of Common Stock to Caledonia and BHGL's
management in the Bristow transaction. The Notes and Common Stock were issued
pursuant to Regulation S under the Securities Act of 1933. Caledonia agreed not
to make any disposition of its Notes or Common Stock in or into the United
States prior to January 29, 1997 and BHGL's management agreed not to make any
such dispositions of such Common Stock prior to January 29, 1998. Because two
representatives of Caledonia are members of the Board of Directors of the
Registrant, Caledonia may be deemed to be an "affiliate" of the Registrant.

                          INDEPENDENT AUDITORS' REPORT
 
The Stockholders'
Bristow Helicopter Group Limited
 
  We have audited the accompanying consolidated balance sheets of Bristow
Helicopter Group Limited as at 31 December 1995 and 1994, and the related
consolidated profit and loss accounts and cash flow statements for each of the
years in the three year period ended 31 December 1995. These consolidated
financial statements are the responsibility of the management of Bristow
Helicopter Group Limited. Our responsibility is to express an opinion on these
consolidated financial statements based on our audits.
 
  We conducted our audit in accordance with generally accepted auditing
standards in the United Kingdom, which standards are substantially equivalent
to auditing standards generally accepted in the United States. Those standards
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. An audit also includes assessing the
accounting principles used and significant estimates made by management, as
well as evaluating the overall financial statement presentation. We believe
that our audits provide a reasonable basis for our opinion.
 
  In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Bristow
Helicopter Group Limited as at 31 December 1995 and 1994, and the results of
its operations and its cash flows for each of the years in the three year
period ended 31 December 1995, in conformity with generally accepted accounting
principles in the United Kingdom.
 
  Accounting principles generally accepted in the United Kingdom vary in
certain respects from accounting principles generally accepted in the United
States. Application of accounting principles generally accepted in the United
States would have affected results of operations for each of the years in the
three-year period ended 31 December 1995 and shareholders' funds as at 31
December 1995 and 1994, to the extent summarised in note 27 to the consolidated
financial statements.

                NOTES (forming part of the financial statements)
 
1. ACCOUNTING POLICIES
 
  The following accounting policies have been applied consistently in dealing
with items which are considered material in relation to the Group's financial
statements.
 
 Basis of preparation
 
  The financial statements have been prepared in accordance with applicable
accounting standards and under the historical cost accounting rules on a going
concern basis.
 
 Basis of consolidation
 
  The Group financial statements consolidate the accounts of Bristow Helicopter
Group Limited and its subsidiary undertakings (see note 25). These financial
statements are made up to 31 December 1995 and 1994. For associated
undertakings the Group includes its share of profits and losses in the
consolidated profit and loss account and its share of post acquisition
accumulated retained profits or deficits in the consolidated balance sheet.
 
  The consolidated financial statements are based on accounts of subsidiary
undertakings which are coterminous with those of the parent company and on
accounts of associated undertakings which are coterminous with or end no more
than three months before those of the parent company.
 
  Unless otherwise stated, the acquisition method of accounting has been
adopted. Under this method, the results of subsidiary and associated
undertakings acquired or disposed of in the period are included in the
consolidated profit and loss account from the date of acquisition or up to the
date of disposal. Goodwill arising on consolidation (representing the excess of
the fair value of the consideration given over the fair value of the separable
net assets acquired) is taken to a goodwill write-off reserve. Any excess of
the aggregate of the fair value of the separable net assets acquired over the
fair value of the consideration given (negative goodwill) is credited direct to
reserves.
 
  On the subsequent disposal or termination of a previously acquired business,
the profit or loss on disposal or termination is calculated after charging the
gross amount of any related goodwill previously taken to reserves.
 
  The amount of the profit for the financial year dealt with in the financial
statements of Bristow Helicopter Group Limited is disclosed in note 17 to these
accounts.
 
 Turnover
 
  Turnover represents total revenue receivable for the period exclusive of VAT
and intra-group transactions.
 
 Leased Assets
 
  Assets held under finance leases are treated as tangible fixed assets;
depreciation is provided over the estimated useful life of the assets and the
deemed capital element of future rentals is included under creditors. Deemed
interest, calculated on a reducing balance basis, is charged as interest
payable over the period of the lease.
 
  The rental costs arising from operating leases are charged against profit
before interest as they arise.

                               NOTES (continued)
 
1. ACCOUNTING POLICIES (continued)
 
 
 Depreciation of Tangible Fixed Assets
 
  Depreciation is provided at rates calculated to write off the cost of the
assets, less estimated residual value, either in the case of the Eurocopter
AS332L, the new Sikorsky S76A + and the Bell 214ST helicopters, on a flying
hour basis, or by equal instalments over their estimated useful economic life
as follows:--

   Freehold buildings......................................... 0-40 years
   Freehold land.............................................. Not depreciated
   Long leasehold property.................................... over lease period
   Short leasehold property................................... over lease period
   Plant and equipment........................................ 3-10 years
   Vehicles................................................... 3-5 years
   Helicopters, aircraft and capital spares................... 8-15 years
</TABLE>
 
 Research and Development
 
  Research and Development expenditure is written off against profits in the
period in which it is incurred.
 
 Taxation
 
  The charge for taxation is based on the profit for the period and takes into
account taxation deferred because of timing differences between the treatment
of certain items for taxation and accounting purposes. Provision is made for
deferred tax only to the extent that it is probable that an actual liability
will crystallise.
 
 Provisions for Component Overhauls
 
  A provision for component overhauls is made on an hourly basis in respect of
the major components of all twin-engine helicopters and certain fixed wing
aircraft. Component overhauls in respect of the major components of single
engine helicopters and certain fixed wing aircraft are charged to trading
profit as costs are incurred.
 
 Foreign Currencies
 
  The trading results of overseas subsidiaries and associated companies are
translated into sterling at average exchange rates for the period.
 
  Assets and liabilities denominated in foreign currencies are translated into
sterling either at the rates ruling at the Balance Sheet date or, where there
are related forward foreign exchange contracts, at contract rates. Exchange
differences arising from the translation of the results of overseas
subsidiaries and associated companies at average rates, and the re-translation
of the opening net investments in overseas subsidiaries and associated
companies, are dealt with in Group reserves. All other exchange differences are
dealt with in the profit and loss account.
 
 Deep Discounted Loan Notes, Loan Stock and Term Loans
 
  The loans are stated in the Balance Sheet at cost plus accrued interest to
date.
 
  Interest is allocated to the Profit and Loss Account at a constant rate over
the term of the loan.
 
 Stocks
 
  Consumable spares and minor rotable stocks are stated at the lower of cost or
net realisable value.

                               NOTES (continued)
 
1. ACCOUNTING POLICIES (continued)
 
 
  Work in progress and stocks for resale are valued at the lower of cost,
inclusive of appropriate overheads, or net realisable value.
 
 Pension Costs
 
  The Group operates pension schemes providing benefits based on final
pensionable pay. The assets of the schemes are held separately from those of
the Group in an independently administered fund. Contributions to the scheme
are charged to the profit and loss account so as to spread the cost of pensions
over employees' working lives with the Group.
 
2. TURNOVER AND PROFIT ON ORDINARY ACTIVITIES BEFORE TAXATION
 
  Segmental reporting as required by Statement of Standard Accounting Practice
No. 25 and analysis of turnover by geographical location and attributable
market as required by the Companies Act 1985 have not been included in these
financial statements as the Directors regard such disclosure as being seriously
prejudicial to the interests of the business.

22. OWN SHARES
 
  The Group set up an Employee Share Scheme shortly after the management buyout
of the Group in November 1991 to enable employees to acquire shares in the
Group. The shares are held on behalf of the participating employees by Bristow
Nominees Limited, which acts at all times in accordance with the provisions of
the Trust Deed and Rules of the Employee Share Scheme.
 
  The amount shown as "Own shares" under current assets in the balance sheet at
31 December 1995 of (Pounds)1,221,000 (at 31 December 1994--(Pounds)88,000)
represents the outstanding loan to Bristow Nominees Limited used to finance the
repurchase of shares from leavers at the prevailing valuation. The total number
of "C" ordinary shares of 5p each held by Bristow Nominees Limited at 31
December 1995 was 13,190,000.
 
23. CONTINGENT LIABILITIES
 
  The Company is party to an agreement dated 7 November 1991, guaranteeing the
obligations of the Company and its subsidiary undertakings and charging its
undertakings and property as security for such guarantees or obligations which
have arisen or may arise pursuant to the bank loans and overdrafts, revolving
and guarantee facilities, provided to the Company and its subsidiary
undertakings by National Westminister Bank plc., The Governor and Company of
the Bank of Scotland and 3i Group plc. On 31 December 1995 the amount due under
the revolving and guarantee facilities was (Pounds)1.9 million (1994--
(Pounds)3.0 million).
 
24. PENSION SCHEME
 
  The Group pension schemes commenced on 31 January 1992. Prior to this date
employees were members of pension schemes operated by The Bricom Group Limited.
Independent actuaries have confirmed that the schemes were fully funded at the
date of transfer from the Bricom Group Schemes to the Bristow Group Schemes and
established the contribution rates to be adopted.

  The Group pension schemes provide benefits based on final pensionable
earnings. The assets of the schemes are held in separate trustee administered
funds and contributions are invested independently of the Group's assets. The
schemes are of the defined benefit type funded by contributions partly from
employees and partly from Group companies at rates determined by independent
actuaries on the basis of triennial valuations. The last actuarial assessment
of the schemes was at 31 March 1995 which showed the market value of the
schemes assets was (Pounds)76.7m. The level of funding being the actuarial
value of assets expressed as a percentage of the benefits accrued to members,
after allowing for future salary increases, was 96.7% at 31 March 1995. On the
preliminary advice of the actuary, the Group has increased the employers
contributions by a further one percent from 1 April 1995 to commence the
elimination of this deficit.
 
  The main actuarial assumptions used to determine the level of contributions
are that the long term annual rate of return on investments would be 2.75% in
excess of annual increases in pensionable earnings and 5.5% in excess of annual
increases to pensions.
 
  The charge for providing pension benefit for the year to 31 December 1995 was
(Pounds)3,859,429 (31 December 1994--(Pounds)3,905,353).

26. DIFFERENCES BETWEEN UNITED KINGDOM AND UNITED STATES GENERALLY ACCEPTED
ACCOUNTING PRINCIPLES
 
  The financial statements are prepared in accordance with accounting
principles generally accepted in the United Kingdom ("UK GAAP") which differ in
certain respects from those generally accepted in the United States ("US
GAAP"). The significant areas of difference affecting the financial statements
of Bristow Helicopter Group Limited are described below.
 
 (a) Goodwill
 
  Under UK GAAP Bristow sets off goodwill arising on consolidation directly
against retained earnings in the year of acquisition. Under US GAAP, goodwill
arising on consolidation is capitalised on the balance sheet and then amortized
over its useful life. Having considered all the relevant factors, Bristow have
determined the expected useful life of goodwill to be 25 years.

26. DIFFERENCES BETWEEN UNITED KINGDOM AND UNITED STATES GENERALLY ACCEPTED
ACCOUNTING PRINCIPLES (continued)
 
 (b) Deferred taxation
 
  Under UK GAAP Bristow provides for deferred taxation using the liability
method on all material timing differences to the extent that it is considered
probable that the liabilities will crystallise in the foreseeable future. Under
US GAAP as set out in Statement of Financial Accounting Standards ("FAS") No
109 "Accounting for Income Taxes", deferred taxation is provided for all
temporary differences on a full liability basis.
 
 (c) Pensions
 
  Under UK GAAP Bristow accounts for pension costs in accordance with Statement
of Standard Accounting Practice (SSAP) 24 on a long-term basis, spreading the
expected pension costs over the service lives of employees, using assumptions
as advised by an independent actuary.
 
  Under US GAAP, in accordance with FAS 87, "Employers' Accounting for
Pensions" the cost of providing pensions is attributed to periods of service in
accordance with the benefit formulas underlying the pension plans. The
resultant projected benefit obligation is matched against the current value of
the underlying plan assets and any unrecognised actuarial gains and losses in
determining the pension cost or credit for the year.
 
 (d) Own share
 
  Under UK GAAP Bristow presents the outstanding loan to Bristow Nominees
Limited used to finance the repurchase of shares from leavers as "Own shares"
under current assets.
 
  Under US GAAP such loan would be presented as a reduction of shareholders'
funds.
 
 (e) Statement of cash flows
 
  Under UK GAAP, cash flows are presented separately for operating activities,
returns on investments and servicing of finance, taxation, investing activities
and financing activities. Under US GAAP, cash flow activities are reported as
operating activities, investing activities and financing activities. Cash flows
from taxation and returns on investments and servicing of finance would, with
the exception of dividends paid and cost of financing, be included as operating
activities. The payment of dividends and cost of financing would be included
under financing activities.
 
  Under UK GAAP, cash and cash equivalents include bank loans and overdrafts
repayable within three months from the date of the advance. Under US GAAP such
cash flow activities are included under financing activities.

                NOTES (forming part of the financial statements)
 
 
1. BASIS OF PRESENTATION
 
  The accompanying interim consolidated financial statements of Bristow
Helicopter Group Limited as at 30 September 1996 and 31 December 1995 and for
the nine months ended 30 September 1996 and 1995 are unaudited. In the opinion
of management, all adjustments (consisting only of normal recurring
adjustments) necessary for a fair presentation of the financial statements have
been included therein. The results of these interim periods are not necessarily
indicative of results for the year.
 
  For the purposes of these consolidated interim financial statements, certain
information and disclosures normally included in financial statements prepared
in accordance with accounting principles generally accepted in the United
Kingdom have been omitted. These unaudited financial statements should be read
in conjunction with the audited financial statements and notes thereto as at
and for the year ended 31 December 1995.
 
2. DIFFERENCES BETWEEN UNITED KINGDOM AND UNITED STATES GENERALLY ACCEPTED
ACCOUNTING PRINCIPLES
 
  The financial statements are prepared in accordance with accounting
principles generally accepted in the United Kingdom ("UK GAAP") which differ in
certain respects from those generally accepted in the United States ("US
GAAP"). The significant differences are described below.
 
 (a) Goodwill
 
  Under UK GAAP Bristow sets off goodwill arising on consolidation directly
against retained earnings in the year of acquisition. Under US GAAP, goodwill
arising on consolidation is capitalized on the balance sheet and then amortised
over its useful life. Having considered all the relevant factors, Bristow have
determined the expected useful life of goodwill to be 25 years.
 
 (b) Deferred taxation
 
  Under UK GAAP Bristow provides for deferred taxation using the liability
method on all material timing difference to the extent that it is considered
probable that the liabilities will crystallise in the forseeable future. Under
US GAAP, as set out in Statement of Financial Accounting Standards ("FAS") No
109 "Accounting for Income Taxes", deferred taxation is provided for all
temporary differences on a full liability basis.
 
 (c) Pensions
 
  Under UK GAAP Bristow accounts for pension costs on a long-term basis,
spreading the expected pension costs over the service lives of employees, using
assumptions as advised by an independent actuary.
 
 Under US GAAP, in accordance with FAS 87, "Employers' Accounting for
Pensions," the cost of providing pensions is attributed to periods of service
in accordance with the benefit formulas underlying the pension plans. The
resultant projected benefit obligation is matched against the current value of
the underlying plan assets and any unrecognised actuarial gains and losses in
determining the pension cost or credit for the year.
 
 (d) Own share
 
  Under UK GAAP Bristow presents the outstanding loan to Bristow Nominees
Limited used to finance the repurchase of shares from leavers as "Own shares"
under current assets.
 
  Under US GAAP such loan would be presented as a reduction of shareholders'
funds.

                               NOTES (continued)
 
 
 (e) Statement of cash flows
 
  Under UK GAAP, cash flows are presented separately for operating activities,
returns on investments and servicing of finance, taxation, investing activities
and financing activities. Under US GAAP, cash flow activities are reported as
operating activities, investing activities and financing activities. Cash flows
from taxation and returns on investments and servicing of finance would, with
the exception of dividends paid and cost of financing, be included as operating
activities. The payment of dividends and cost of financing would be included
under financing activities.
 
  Under UK GAAP, cash and cash equivalents include bank loans and overdrafts
repayable within three months from the date of the advance. Under US GAAP such
cash flow activities are included under financing activities.
 
3. SUMMARY OF DIFFERENCES BETWEEN GENERALLY ACCEPTED ACCOUNTING PRINCIPLES IN
THE UNITED KINGDOM AND THE UNITED STATES
 
  The approximate effects of the differences between UK GAAP and US GAAP on net
income and shareholders' funds is as follows:

        UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
 
  The following unaudited pro forma condensed consolidated financial
information is derived from the historical financial statements of OLOG and
Bristow and certain assumptions deemed appropriate by the Company. The
Unaudited Pro Forma Condensed Consolidated Statements of Income for the 12
months ended June 30, 1996 and the three months ended September 30, 1996
reflects (i) the Bristow Transaction and (ii) the issuance of the Notes and
the application of the net proceeds therefrom, as if such transactions had
occurred on July 1, 1995. The Unaudited Pro Forma Condensed Consolidated
Balance Sheet as of September 30, 1996 reflects such transactions as if they
had occurred on September 30, 1996. The Unaudited Pro Forma Condensed
Consolidated Financial Statements should be read in conjunction with the notes
thereto and the historical financial statements of OLOG, including the notes
thereto, included in the Company's Form 10-K and the historical financial
statements of Bristow, including the notes thereto, included elsewhere herein.
 
  The pro forma adjustments to give effect to the various events described
above are based upon currently available information and upon certain
assumptions that management believes are reasonable. Bristow's historical
financial data included in these pro forma statements have been restated to
conform with U.S. GAAP. For a discussion of the principal differences between
U.K. and U.S. GAAP, see Notes 26 and 27 to Bristow's Consolidated Financial
Statements. The Bristow Transaction will be accounted for by the Company under
the purchase method of accounting and the assets and liabilities of Bristow
will be recorded at their estimated fair market values at the date of
acquisition. The adjustments included in the Unaudited Pro Forma Combined
Financial Statements reflect the Company's preliminary determination of these
adjustments based upon available information. There can be no assurance that
the actual adjustments will not vary significantly from the estimated
adjustments reflected in the Unaudited Pro Forma Condensed Consolidated
Financial Statements. Bristow's September 30, 1996 historical balance sheet
was translated from British Pounds Sterling to U.S. Dollars using the exchange
rate on that date of 1.5634. The income statements for the three months ended
September 30, 1996 and 12 months ended June 30, 1996 were translated using a
weighted average exchange rate of 1.5547 and 1.5475, respectively.
 
  The Unaudited Pro Forma Condensed Consolidated Financial Statements do not
purport to be indicative of the financial position or results of operations
that would actually have occurred if the transactions described had occurred
as presented in such statements or that may be obtained in the future. In
addition, future results may vary significantly from the results reflected in
such statements due to general economic conditions, oil and gas commodity
prices, the demand and prices for oil and gas related offshore transportation
services, increases in the number of helicopters available for service, the
exchange rate between U.S. Dollars and British Pounds Sterling, and several
other factors, many of which are beyond the Company's control.

adjustments are based on estimates made by the Company's management using
information currently available.
 
  The adjustments to the accompanying Unaudited Pro Forma Condensed
Consolidated Balance Sheet are described below.
 
  a.  To record existing OLOG cash used to finance a portion of the Bristow
      Transaction.
 
  b.  To record the cash investment to secure the Caledonia put option.
 
  c.  To record a write-up of Bristow's inventory to fair value.
 
  d.  To record the write-off of Bristow's existing accumulated depreciation
      and to record the write-up of Bristow's fixed assets to fair value.
 
  e.  To record the write-off of Bristow's existing goodwill and to record the
      goodwill associated with the Bristow Transaction.
 
  f.  To record the issuance of $87.5 million of the Notes, the write-up of
      assumed Bristow debt with higher than market interest rates to fair value
      ($6.7 million), the obligation for Newco management fees payable to
      Caledonia ($4.9 million) and the elimination of certain Bristow
      subordinated debt acquired by OLOG.
 
  g.  To eliminate Bristow's accrued maintenance and repairs provision given
      the write-up of fixed assets to fair value and to eliminate Bristow's
      pension liability as the fair value of the plan assets approximates the
      actual liability of pension obligation.
 
  h.  To record recognition of deferred taxes for the pro forma adjustments
      except for the goodwill recorded, and to adjust Bristow's existing
      deferred tax assets.

  k.  To adjust the maintenance and repairs provision and pension expense of
      Bristow.

      stepped up basis of fixed assets and goodwill. Fixed assets of Bristow
      will be depreciated over 10 to 15 years with residual values of 30% to
      50%. Goodwill and transaction costs will be amortized over 30 years.
 
  m.  To record reduced interest income as a result of the use of OLOG's
      existing cash equivalent balances to finance a portion of the Bristow
      Transaction.
 
  n.  To record interest expense adjustments related to the Notes offering at
      an assumed annual interest rate of 6%, certain subordinated debt held by
      U.K. institutional investors to be acquired by OLOG in the Bristow
      Transaction, the restatement of certain assumed debt to reflect market
      interest rates and amortization of deferred debt issuance costs related
      to the Notes over the term of the Notes (ten years).
 
  o.  To record the tax effect of the income statement adjustments (at 33% for
      applicable Bristow adjustments and 34% for applicable OLOG adjustments).
 
 
  p.  To record the minority interest accruals at 12% as specified in the call
      arrangements between OLOG, Caledonia and the EU Investor.
 
  q.  The pro forma weighted average shares outstanding includes the issuance
      of 1,374,000 of OLOG shares.

     implied, statutory or otherwise are expressly excluded.

6.6  Any payment made by any of the Vendors pursuant to the terms of this
     Agreement shall be treated by the parties as a reduction pro tanto of the
     purchase price payable by him/it for the Shares.

6.7  The sole remedy of OLOG and OLII in respect of any claim for breach of
     Warranty under Part 1 or Part II of Schedule 9 shall be in damages. OLOG
     and OLII shall have no right to rescind or terminate this Agreement for
     breach of Warranty unless at any time after the date of this Agreement and
     prior to Completion there occurs any act or event constituting a material
     breach of Warranty at the date of this Agreement or which would constitute
     a material breach of Warranty if such Warranty were repeated on any day
     from the date of this Agreement to and including the Completion Date. In
     such case OLOG or OLII shall be entitled by notice in writing on the other
     parties to this Agreement not to proceed to Completion in which event this
     Agreement shall be of no effect and no party shall have any further
     liability to the other. Completion of the

<PAGE>
 
     transaction contemplated by this Agreement in circumstances where OLOG or
     OLII are actually aware that a right to rescind has arisen shall constitute
     a waiver by OLOG and OLII of its rights in respect of the relevant breach.
     For the purposes of this Clause 6.7 an act or event shall constitute a
     "material breach" of warranty if it is both a breach of warranty and an act
     or event which is material and adverse to the assets and liabilities,
     financial position, profits and losses, or prospects of the Group taken as
     a whole.

7.   ANNOUNCEMENTS

     Save where an announcement is required by law or the rules of London Stock
     Exchange Limited, NASDAQ or any other exchange upon which the securities of
     Caledonia or OLOG are traded or dealt, none of the parties shall make, or
     procure or permit the making of, any announcement whether before or after
     Completion with respect to this Agreement or any ancillary matter without
     the prior consent of OLOG, Caledonia and Morgan Grenfell Development
     Capital Nominees Limited.

8.   ASSIGNMENT

     Any party may assign its rights under this Agreement after Completion and
     this Agreement shall be binding on and enure for the benefit of the
     parties' successors, assigns and personal representatives.

9.   ENTIRE AGREEMENT

     This Agreement, together with the First Disclosure Letter, the Second
     Disclosure Letter and the documents in the agreed form, represents the
     entire understanding, and constitutes the whole agreement, in relation to
     its subject matter and supersedes any previous agreement between the
     parties with respect thereto and without prejudice to the generality of the
     foregoing in the absence of fraud or wilful misrepresentation, excludes any
     warranty, condition or other undertaking implied at law or by custom.

10.  FURTHER ASSURANCE

10.1 So far as it remains to be performed this Agreement shall continue in full
     force and effect notwithstanding Completion.

10.2 Each of the parties shall after Completion execute all such deeds and
     documents and do all such things as any other party may reasonably require
     for perfecting the transactions intended to be effected under or pursuant
     to this Agreement.

<PAGE>
 
     of six months starting on the day of notification of the claim, unless
     proceedings in respect of the claim have been issued and served on that
     Individual Manager.

11.  No Individual Manager shall have any liability in respect of a claim under
     Part I of Schedule 9 to the extent that the matter giving rise to the
     claim would not have arisen but for:

11.1 An event after the Completion Date caused by a member of the OLOG Group or
     a director, employee, agent or adviser of the OLOG group;

11.2 the passing of or a change in, after the date of this Agreement, a law,
     rule, regulation, interpretation of the law or administrative practice of
     a government, governmental department, agency or regulatory body, a change
     in any area of accounting principle or practice generally accepted in any
     jurisdiction or an increase in the tax rates or an imposition of tax, in
     each case not actually or prospectively in force at the date of this
     Agreement;

11.3 a change in accounting policy or practice of any member of the Group after
     the Completion Date;

     authorised director, employee, agent or adviser of the OLOG Group;

11.5 to the extent that the matter giving rise to the claim was specifically
     taken into account in computing the amount of an allowance, provision or
     reserve in the Accounts or was specifically referred to in the Accounts or
     in the directors report attached to the Accounts;

11.6 to the extent that the matter giving rise to the claim is a tax liability
     of any Company or Subsidiary arising because the assets of any Company or
     Subsidiary are more than, or its liabilities are less than, were stated in
     the Accounts;

11.7 to the extent that the matter giving rise to the claim is a tax liability
     against which a relief arising on or before Completion and not shown as an
     asset in the Accounts is utilised; and

11.8 to the extent that any Company or Subsidiary obtains the benefit of a
     relief (other than a deferred relief) in an accounting period ending after
     the Accounts Date for an expenditure, reserve or provision which was
     specifically taken into account in the Accounts so as to reduce the net
     assets of a Company or Subsidiary but was not, in preparing the Accounts,
     treated as non-deductible or non-allowable for tax purposes so as to
     increase the provision for tax in the Accounts.

12.  OLOG and OLII are not entitled to recover more than once in respect of any
     one matter giving rise to a claim.

13.  If any member of the Group is entitled to recover from another person a sum
     which relates to a matter which has given, or might give, rise to a claim
     and any Individual Manager has first agreed (to OLOG and OLII's reasonable
     satisfaction) to indemnify Bristow against all costs which Bristow or any
     other member of the Group may incur

                                       43
<PAGE>
 
     in connection with the taking of the following action, then, at that
     Individual Manager's request, Bristow shall, and shall ensure that the
     Group will, take any action reasonably requested by that Individual Manager
     to enforce recovery against the other person and where prior to such
     recovery the Individual Managers (or some thereof) have made payment to
     OLOG and OLII in settlement of the claim under the Warranties, OLOG and
     OLII shall account to each Individual Manager for the lesser of:

13.1 the appropriate share of the sum recovered (including any interest paid by
     the other person), net of any reasonable costs incurred in making recovery
     (save where such costs have been met by any Individual Manager) having
     regard to paragraph 3 above; and

13.2 the amount paid by the Individual Manager in respect of such claim.

14.  Nothing in this Schedule 10 restricts or limits any general obligation at
     law of OLOG and OLII to mitigate any loss or damage which it may incur in
     consequence of a matter giving rise to a claim.

15.  IF at any time after the date of this Agreement any of the Individual
     Managers wishes to insure against his liabilities in respect of claims,
     OLOG and OLII shall provide such information as it is able and which a
     prospective insurer may reasonably require for the purposes of effecting
     the insurance.

16.  OLOG and OLII shall, and shall ensure that each member of the Group will
     preserve all documents, records, correspondence, accounts and other
     information whatsoever relevant to a matter which may give rise to a claim
     under the Warranties until the expiry of three years from the date of this
     Agreement.

17.  In assessing any damages or other amounts recoverable for a claim there
     shall be taken into account any corresponding savings by, or net benefit
     to, the OLOG Group in connection with the facts or circumstances giving
     rise to such claim.
