ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS

          In February 1998, the Company agreed to acquire all of the outstanding
capital stock of Sea Mar, Inc. ("Sea Mar") from Al A. Gonsoulin and Gonsoulin
Enterprises, Inc. for a purchase price estimated to be $110.4 million,
consisting of approximately $76.1 million in cash (including an estimated $14.7
million in closing adjustments) and 1,538,462 common shares of Pool Energy
Services Co. ("the Company") (approximate value of $34 million as of February
10, 1998).  In addition, the Company has agreed to pay additional cash
consideration contingent upon Sea Mar exceeding certain earnings before
interest, taxes, depreciation and amortization and minority interest ("EBITDA")
targets for the fiscal years ending December 31, 1998 and 1999 of $25 million
and $35 million, respectively. The additional consideration for each year will
be equal to the amount by which EBITDA exceeds the EBITDA target for the
applicable year, up to a maximum of $10 million in each year. The purchase price
was derived from an arms-length negotiation using projected and historical
EBITDA.  Immediately after the closing of the Sea Mar acquisition, which is
expected to occur on or about March 31, 1998, the Company intends to repay Sea
Mar's existing debt of approximately $17.1 million.  The Company expects to
finance the acquisition with funds from its line of credit with its senior
lenders or through a private placement of the Company's debt securities.

         Sea Mar is a privately-owned operator of offshore support vessels in
the Gulf of Mexico.  Sea Mar's services include the marine transportation of
drilling materials, supplies and crews for offshore rig operations and support
for other offshore facilities.  Sea Mar also provides offshore logistical
support to drilling and workover operations, pipelaying and other construction,
production platforms and geophysical operations.  Sea Mar's existing fleet
consists of 24 support vessels, including one anchor handling/tug supply vessel
(200 feet), 14 supply vessels (between 166 and 220 feet), seven mini-supply
vessels (between 130 and 150 feet) and two research vessels. Except for three
smaller vessels, Sea Mar, within the past five years, completed an extensive
refurbishment and upgrade program to its existing fleet, which extended the
estimated remaining useful lives of each of the vessels to approximately 15
years.  In addition, during 1997 a contract was entered into with a marine
shipbuilder for the construction of ten additional vessels at an aggregate cost
of $86.8 million, net of deposits. These new vessels are scheduled to be
delivered between late 1998 and early 2000.  For the year ended December 31,
1997, Sea Mar had revenues of $45.8 million and EBITDA of $28.4 million before
charges of $4.1 million. Such charges were for expenditures related to a
guarantee no longer in place and supplemental compensation to Al A. Gonsoulin,
Sea Mar's Chief Executive Officer.

ITEM 5.  OTHER EVENTS

         Subsequent to the execution of the Sea Mar purchase agreement described
in Item 2, Sea Mar was notified by Rowan Companies, Inc. ("Rowan") that it was
repudiating and terminating charter agreements with Sea Mar for the use of four
vessels that Sea Mar presently has under construction.  Sea Mar and Mr.
Gonsoulin have sued Rowan seeking specific performance and any damages that may
result from wrongful breach of the charter agreements.  Rowan subsequently also
filed suit seeking a declaration that the charter agreements are void.
Regardless of the outcome of this matter, the Company is confident that this
development will not have a material adverse impact on the Company.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Shareholder
of Sea Mar, Inc.:
 
We have audited the accompanying consolidated financial statements of Sea Mar,
Inc. (a Louisiana corporation) and subsidiaries (the "Company") as of December
31, 1997 and 1996, and the related statements of operations, shareholder's
investment and cash flows for the years then ended. These financial statements
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statements based on our audits.
 
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits 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 Sea Mar, Inc. and
subsidiaries as of December 31, 1997 and 1996, and the results of their
operations and their cash flows for the years then ended in conformity with
generally accepted accounting principles.

                         SEA MAR, INC. AND SUBSIDIARIES
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. NATURE OF OPERATIONS AND ACCOUNTING POLICIES
 
     Sea Mar, Inc. ("Sea Mar") was formed in 1990 as a Louisiana corporation and
began operations by issuing 40 shares of Class A common stock in exchange for
the stock of the previous Sea Mar, Inc., a company with related ownership.
Effective January 1, 1997, Sea Mar Personnel, Inc. and Sea Mar Operators, Inc.,
previously wholly owned subsidiaries of Sea Mar, were merged into Sea Mar, Inc.
The merger was accounted for as a reorganization similar to a pooling of
interests. The accompanying consolidated financial statements include the
accounts of Sea Mar and its wholly owned subsidiary, Sea Mar Management, Inc.
(collectively the "Company"). All significant intercompany balances and
transactions have been eliminated in consolidation.
 
     The Company provides vessel support services to major and independent oil
and gas exploration and development companies, drilling contractors, geophysical
companies, construction companies and well stimulation and cementing companies
operating offshore. Such services are provided on a time charter basis utilizing
a fleet of vessels owned and/or managed by the Company. Typically, revenues are
earned based on a charge per day of service provided and are recorded for each
day worked. At December 31, 1997, the Company was providing these services only
in the Gulf of Mexico. However, in the past the Company has provided these
services on a worldwide basis and expects to operate in foreign waters in the
future.
 
  Accounts Receivable
 
     Customers are primarily major and large independent oil and gas exploration
and production companies. The Company's customers are granted credit on a
short-term basis and related credit risks are considered minimal. No allowance
has been provided by doubtful accounts at December 31, 1997 or 1996.
 
  Revenue Recognition
 
     The Company earns revenue from time charters of vessels to customers based
upon daily rates of hire. Rates of hire earned under time charters vary in
proportion to the operating expenses incurred in conjunction with each type of
charter. Typically, under time charter arrangements, the vessels' operating
expenses are the responsibility of the Company.
 
  Property and Equipment
 
     Property and equipment is recorded at cost. Maintenance and minor
replacements are charged to operations as incurred; major replacements and
betterment's are capitalized. The costs of assets sold, retired or otherwise
disposed of are removed from the accounts at the time of disposition, and any
associated gain or loss is reflected in operations for the period.
 
     For financial reporting purposes, depreciation is provided on a
straight-line basis (with salvage values of 10% for vessels) over the estimated
useful lives of the assets as follows:

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

  Income Taxes
 
     The Company accounts for income taxes under Statement of Financial
Accounting Standards No. 109, "Accounting for Income Taxes" ("SFAS 109"). SFAS
109 is an asset and liability approach that requires the recognition of deferred
tax assets and liabilities for the expected future tax consequences of events
that have been recognized in the Company's financial statements or tax returns.
In estimating future tax consequences, SFAS 109 generally considers all expected
future events other than enactments of changes in the tax law or rates.
 
  Estimates and Assumptions
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Deferred Drydock Costs
 
     The Company periodically incurs drydock costs in conjunction with marine
inspections. These drydock costs are capitalized and amortized on a
straight-line basis over a period not to exceed 30 months.
 
2. LONG-TERM DEBT
 
     In January 1996, the Company refinanced its outstanding long-term debt of
$11,166,667, with a $15,000,000 secured term loan ("Secured Term Loan I"). The
proceeds were used to retire the previous credit facility, provide additional
working capital and $2,600,000 was used toward the purchase of an additional
vessel. Between January, 1996 and August, 1996, the Secured Term Loan I was
increased from $15,000,000 to $19,400,000 and additional draws of up to maximum
available were made with the proceeds used to purchase vessels.
 
     In December 1996, the Company renegotiated and refinanced its Secured Term
Loan I with a new credit facility ("Credit Facility") in the amount of
$40,000,000. Of the $40,000,000 Credit Facility, $20,000,000 is characterized as
a secured term loan ("Secured Term Loan II") and $20,000,000 is characterized as
a capital expenditure loan ("Capital Expenditure Loan"). All of the $20,000,000
available under the Secured Term Loan II was drawn in December 1996 with the
proceeds used to repay the borrowings under Secured Term Loan I and for
additional working capital. The Secured Term Loan II bears interest, at the
Company's option, of either 1.85% over LIBOR or the annual rate of a seven-year
United States Treasury Note plus 1.85%. It is due in monthly installments of
$238,095 plus interest for fifty-nine consecutive months with a final balloon
payment in December 2001.
 
     At December 31, 1997 and 1996, the Company had no debt outstanding under
its Capital Expenditure Loan. The Capital Expenditure Loan may be used for
vessel acquisition or construction and general working capital. The terms of the
Capital Expenditure Loan provide for interest, at the Company's option, of
either 2.00% over LIBOR or the annual rate of a seven-year United States
Treasury Note plus 2.00%. Payment terms under the Capital Expenditure Loan
provide that only interest is payable through June 30, 1998, with monthly
installments of principal beginning July 31, 1998 and a final balloon payment
due on June 30, 2003.
 
     The Credit Facility imposes restrictions on the payment of dividends.

4. RELATED-PARTY TRANSACTIONS
 
     As of December 31, 1997 and 1996, the Company had receivables of $0 and
$53,708, respectively, from its shareholder. Additionally, as of December 31,
1997 and 1996, the Company had receivables (payables) of ($26,681) and $3,154,
respectively, from (to) affiliated companies owned by its shareholder. The
Company also paid $2,400,000 to an affiliated company for guaranty fees during
the year ended December 31, 1997, which is reflected in general and
administrative expenses in the Company's statements of operations.
 
     Beginning January, 1997, the Company is leasing a new office warehouse
complex from an affiliate. The lease is classified as an operating lease and
provides for minimum annual rentals of $156,000 through 2001.
 
     During January 1996, the Company purchased a 175-foot vessel from an
affiliated company in exchange for two 102-foot vessels, $500,000 cash and
$47,508 of costs which were receivable from the affiliate. Also, in 1997 the
Company acquired two vessels from an affiliated company for $3,000,000.
 
     On August 29, 1996, the Board of Directors authorized the Company to redeem
the outstanding 100 shares of preferred stock from its primary stockholder.
 
     In December 1996, the Company sold to an affiliate, a warehouse building
and land for the appraised value of $175,000.
 
5. LEASES

6. PROFIT SHARING
 
     For the year beginning January 1, 1996, the Company began a Profit Sharing
401(k) Plan. The Plan is intended to be a retirement plan qualified under
Internal Revenue Code 401(d). Employer contributions are discretionary with

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
7. CONCENTRATION OF CREDIT RISK
 
     During 1997, the Company provided services to two customers, which
accounted for approximately 22%, or $10,100,000, of 1997 revenues. Under current
market conditions, the Company does not believe that the loss of one or more of
these customers would have a material adverse effect on operating results since
the Company's vessel are capable of providing a wide variety of services to
other customers. The Company grants its customers credit only on a short-term
basis after investigation of credit worthiness. Therefore, even though virtually
all the Company's accounts receivable are from companies in the oil and gas
industry, exposure from the related credit risks are considered insignificant.
During 1996, the Company provided services to three customers, which accounted
for approximately 42%, or $11,600,000, of 1996 revenues.
 
8. PREFERRED STOCK
 
     In July 1994, the Company issued 100 shares, no par value, Class C
Preferred Stock in connection with the reorganization of the Company and the
refinancing of the Company's credit facility. Dividends on the preferred stock
were restricted as provided by the terms of the Company's credit facility. The
preferred stock was redeemable at the option of the shareholder contingent upon
the Company satisfying certain financial requirements as also provided by the
Company's credit facility. The preferred shares were redeemed by the Company
during 1996 for $1,484,000.
 
9. SUBSEQUENT EVENT
 
     On February 10, 1998, the Company signed a Stock Purchase Agreement (the
"Agreement") to sell its outstanding stock to Pool Energy Services Co. (the
"Buyer"). The Agreement provides for the exchange of cash and common stock in
the Buyer for all of the Company's outstanding Class A common stock.
 
     On February 10, 1998, the Company signed an Assignment of Rights Under
Vessel Construction Contract with Sea Mar Equipment, Inc. ("Equipment"), owned
100% by the current shareholder of the Company, to assign all rights and
obligations under a vessel construction contract dated August 1, 1997 between
Equipment and a shipyard in exchange for $10,000,000 to be paid in cash or a one
year promissory note. During 1997, the Company advanced $8,275,000 to Equipment
related to Equipment's vessel construction contract. This advance has been
classified as Vessel Deposits in the accompanying balance sheet. The vessel
construction contract provides for the construction and delivery of ten supply
and anchor-handling/tug supply vessels. Pursuant to the Agreement discussed
above, the Buyer shall fund the Company with either the required $10,000,000 or
a promissory note payable in one year, bearing interest at 7.5%. The proceeds
will be used to repay the advance made during 1997 to Equipment. Total estimated
costs remaining under the vessel construction contract is approximately
$87,000,000.

           UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL DATA
 
      The following presents summary unaudited combined condensed pro forma
financial data of the Company and Sea Mar. The accompanying unaudited pro forma
condensed statement of consolidated operations for the year ended December 31,
1997 was prepared assuming that the Sea Mar Acquisition was completed as of
January 1, 1997. The unaudited pro forma condensed statement of consolidated
operations is based upon (i) the historical statement of consolidated operations
of the Company for the year ended December 31, 1997 and (ii) the historical
consolidated statement of operations of Sea Mar for the year ended December 31,
1997. The unaudited pro forma combined balance sheet has been prepared assuming
that the Sea Mar Acquisition was completed on December 31, 1997. The Unaudited
Pro Forma Consolidated Financial Data and the Notes thereto should be read in
conjunction with "Management's Discussion and Analysis of Financial Condition
and Results of Operations," the historical financial statements of the Company
including notes thereto included in the Company's Annual Report on Form 10-K for
the year ended December 31, 1997 and the historical financial statements of Sea
Mar including notes thereto included elsewhere herein.
 
     The pro forma adjustments are based upon available information and upon
certain assumptions and estimates described in the Notes to the Unaudited Pro
Forma Condensed Financial Data. A final determination of required purchase
accounting adjustments, including the allocation of the purchase price to the
assets acquired and liabilities assumed based on their respective fair values,
has not yet been made. Accordingly, the purchase accounting adjustments
reflected in the pro forma information are preliminary and have been made solely
for purposes of developing such information. The Company's management believes,
however, that the pro forma adjustments and the underlying assumptions and
estimates reasonably present the significant effects of the transactions
reflected thereby and that any subsequent changes in the underlying assumptions
and estimates will not materially affect the pro forma financial statements. The
pro forma financial statements do not purport to represent what the Company's
financial position or results of operations actually would have been had such
transaction occurred on the dates indicated or to project the Company's
financial position or results of operations for any future date or period.
Furthermore, the unaudited pro forma financial statements do not reflect changes
that may occur as the result of post-combination activities and other matters
including, but not limited to, the ultimate contingent consideration that may be
paid (up to a maximum of $20 million) if Sea Mar operations exceed certain
EBITDA targets for fiscal years ending December 31, 1998 and 1999. See Note (i)
to the unaudited pro forma financial statements.

         Historical net asset values acquired:
           Capital stock.........................................         38
           Retained earnings.....................................     22,966
                                                                   ---------

     (b) The pro forma adjustment to cash and cash equivalents
         results from the following:
         Repayment of the existing debt of Sea Mar concurrent
          with the consummation of the acquisition ($17.1 million 
          outstanding at December 31, 1997, which bears interest 
          at a floating rate which was 7.66% at December 31, 
          1997 and has a maturity date of December 2001).........  $ (17,143)
         Repayments on the Company's line of credit..............    (51,800)
                                                                   ---------
           Total debt repayments.................................    (68,943)
                                                                   ---------
         Estimated cash consideration for the acquisition
          (see note (c)).........................................    (76,100)
                                                                   ---------
           Total pro forma decrease in cash and cash
            equivalents..........................................  $(145,043)
                                                                   =========
 
     (c) Estimated cash consideration (includes $10 million
         related to the assignment of the rights under the vessel
         construction contract)..................................  $  60,000
         Estimated post-closing purchase price adjustments.......     14,700
         Estimated acquisition related costs.....................      1,400
                                                                   ---------
           Total estimated cash consideration for the 
            acquisition..........................................     76,100
                                                                   ---------
         Value of the common stock consideration (1,538,462
          shares of the Company's common stock with an estimated
          value of $22 5/16).....................................     34,327
                                                                   ---------
           Total estimated purchase price for the 
            acquisition..........................................    110,427
                                                                   ---------
         Fair value allocated to net assets acquired (see note
          (a))...................................................     76,909
                                                                   ---------
         Goodwill................................................  $  33,518
                                                                   =========
 
     (d) Net cash proceeds of the financing for the acquisition 
         are calculated using the following assumptions:
         Proceeds................................................  $ 150,000
         Less cash used for debt issuance costs..................      5,000
                                                                   ---------
         Net cash proceeds.......................................  $ 145,000
                                                                   =========
     (e) Reflects elimination of historical nonrecurring charges
         of $4.1 million. Such charges were for expenditures
         related to a guarantee no longer in place as a result of
         the acquisition and supplemental compensation to
         the chief executive officer of Sea Mar (which will not
         be recurring as a result of a new employment agreement
         related to the acquisition).

     (f) Reflects additional depreciation expense using a
         weighted average estimated remaining depreciable life of
         12 years ($6,692,000), amortization of goodwill using a
         25 year amortization period ($1,341,000) and
         amortization of a 5-year noncompete agreement
         ($100,000).

     (g) Reflects estimated increase in expense resulting from
         the financing for the acquisition at an assumed
         interest rate of 8 1/4% and amortization of the related
         debt issuance costs over ten years, offset by a decrease
         in interest expense from the debt repayments described
         in note(b) above. A  1/8% change in the interest rate on
         the Notes would change 1997 pro forma interest expense
         by $0.2 million.

     (h) Reflects estimated income taxes for Sea Mar and the pro
         forma adjustments, using a combined federal and state
         rate of 36.8%.

     (i) Total estimated purchase price for the acquisition does
         not include any of the additional maximum $20 million cash
         consideration that is contingent upon Sea Mar exceeding
         certain EBITDA targets for the fiscal years ending
         December 31, 1998 and 1999 of $25 million and $35 million,
         respectively. The additional purchase consideration for
         each year will be equal to the amount by which EBITDA
         exceeds the EBITDA target for the applicable year up to a
         maximum of $10 million in each year. The additional
         purchase consideration, if any, will be reflected as
         additional goodwill. Pro forma annual goodwill
         amortization for the acquisition as shown in note (f)
         would increase $0.2 million for each $5.0 million of
         additional purchase consideration.

<PAGE>   10
         exceptions as to the application of GAAP or as to the scope of the
         audit) a statement of the Company's Shareholders' Equity as of the
         Closing Date.  Such statement, together with all related working
         papers, being herein referred to as the "Statement".  The Statement
         shall be compared with the adjusted pro forma balance sheet as of
         August 31, 1997, a copy of which is attached as Exhibit 5 (the "Pro
         Forma Balance Sheet") and the Shareholders' Equity shown therein.  The
         amount of increase or decrease in the Shareholders' Equity is
         hereinafter referred to as the "Purchase Price Adjustment".  The fees
         and expenses of the Auditors shall be borne by Buyer.

                 (b)      The parties hereto shall use their reasonable best
         efforts to cause the Auditors to complete and deliver the Statement to
         Sellers and Buyer within 90 days after the Closing Date.

                 (c)      If the Purchase Price Adjustment is a positive
         amount, the Purchase Price shall be increased by such amount, with
         such increase being payable in cash by Buyer within fifteen business
         days of the date of the delivery to Buyer of the Statement (the
         "Determination Date").  The amount of any such increase shall be
         allocated among the Sellers in proportion to the allocation of the
         Cash Amount payable at Closing as set forth on Exhibit 1 hereto.  If
         the Purchase Price Adjustment is a negative amount, then the Purchase
         Price shall be reduced by such amount, and the Sellers, shall pay such
         amount to Buyer in proportion to the allocations set forth in Exhibit
         1  within fifteen (15) business days of the Determination Date.

                 (d)      In the event that Buyer, on the one hand, or Seller
         Representative on the other, disagrees with the Statement, such party
         shall have fifteen (15) days from the Determination Date to attempt to
         resolve such dispute with the other.  In the event such dispute cannot
         be resolved, either Buyer or Seller Representative can request, by the
         delivery of a notice to the other specifying in reasonable detail the
         nature of the dispute, within three (3) days of the expiration of such
         fifteen day period, that the dispute be resolved by an independent
         nationally-recognized accounting firm that has no business
         relationship with either party (the "Accounting Arbitrator") selected
         by the party delivering the notice.  The Accounting Arbitrator shall
         review any disputed items and resolve any such disputes within thirty
         (30) days of the date the Accounting Arbitrator is retained.  The
         decision of the Accounting Arbitrator shall be final and binding
         between the parties for the purpose of determining any Purchase Price
         adjustment pursuant to this Section 2.3.  The fees and expenses of the
         Accounting Arbitrator shall be borne one-half by Buyer and one-half by
         Sellers.

         2.4     Payment of Additional Consideration.  In addition to the
Purchase Price, Buyer shall pay to Sellers, or their assigns or successors,
subject to the terms and conditions of this Agreement, additional consideration
as follows:

1998 or 1999, as appropriate, audited consolidated financial statements
,excluding any gain or loss on the disposal of material assets.  EBITDA will be

adjusted 1998 EBITDA and the Adjusted 1999 EBITDA, respectively.

Buyer as of the date hereof and as of the Closing Date, as follows:

                 (a)      Due Organization; Good Standing and Power.  The

         existing and in good standing under the laws of the state of its
         incorporation.  The Company and each Subsidiary has the corporate
         power and authority to own, lease and operate its respective assets

         and each Subsidiary is duly authorized, qualified or licensed to do
         business as a foreign corporation and is in good standing in each
         jurisdiction in which their respective right, title or interest in or
         to any of their respective assets, or the conduct of their respective
         business, requires such authorization, qualification or licensing,
         except where the failure to so qualify or to be in good standing in
         such other jurisdictions would not have a material adverse effect on
         any of the assets, the business or the results of operations of the
         Company or of such Subsidiary.  The jurisdiction of incorporation of
         the Company and each Subsidiary and jurisdictions in

         as the same may be limited by bankruptcy, insolvency or other similar
         laws affecting creditors' rights generally and by general equity
         principles.  The Company's authorized capital consists solely of (i)

         duly authorized and validly issued, are fully paid and nonassessable,
         have not been issued in violation of any preemptive or similar rights,

         acquire from the Company or any Subsidiary, and no obligation of the
         Company or any Subsidiary to issue or sell, any shares of its capital
         stock or other voting securities or any securities of the Company or
         any Subsidiary convertible into or exchangeable for such capital stock
         or voting securities, (iv) no equity equivalents, interest in the
         ownership or earnings, or other similar rights of or with respect to
         the Company or any Subsidiary, and (v) no shares of any other entity

         Closing Date there will be) no outstanding obligations of the Company
         or any Subsidiary to repurchase, redeem or otherwise acquire any
         shares, securities, options, equity equivalents, interests or rights.

         contemplated hereby Buyer will acquire, good, valid and marketable
         title to, the number of shares of Stock set forth opposite the name of
         such Seller on Schedule 3.1(b), free and clear of all Encumbrances,
         other than (i) those that may arise by virtue of any actions taken by
         or on behalf of Buyer or its affiliates or (ii) restrictions on
         transfer that may be imposed by federal or state securities laws.

                 (c)      No Approvals or Notices Required; No Conflict with
         Instruments.  Except as described in Schedule 3.1(c) hereto, the
         execution, delivery and performance of this Agreement by the Sellers
         and the Company and the consummation by them of the transactions
         contemplated hereby (i) will not violate (with or without the giving
         of notice or





                                      -5-
<PAGE>   13
         the lapse of time or both) or require any consent, approval, filing or
         notice under, any provision of any Applicable Law and (ii) will not
         result in the creation of any Encumbrance on the Stock under, conflict
         with, or result in the breach or termination of any provision of, or
         constitute a default under, or result in the acceleration of the
         performance of the obligations of the Sellers, the Company or any
         Subsidiary under, or result in the creation of an Encumbrance upon any
         portion of the assets of the Company or any Subsidiary pursuant to,
         the charters or by-laws of the Company or any Subsidiary, or any
         indenture, mortgage, deed of trust, lease, licensing agreement,
         contract, instrument or other agreement to which the Sellers, the
         Company or any Subsidiary are a party or by which any of them or any
         of their assets is bound or affected.  The Stock is transferable and
         assignable to Buyer as contemplated by this Agreement without the
         waiver of any right of first refusal or the consent of any other party
         being obtained, and there exists no preferential right of purchase in
         favor of any person with respect of any of the Stock or the Business
         or any of the assets of the Company.

                 (d)      Financial Information and Absence of Certain Changes.
         The Company has delivered to Buyer accurate and complete copies of (i)
         the Company's audited consolidated balance sheets as of December
         31,1995 and December 31,1996, and the related audited consolidated
         statements of income, stockholders' equity and cash flows for each of
         the years then ended, and the notes and schedules thereto, prepared in
         conformity with GAAP, together with the unqualified reports thereon of
         Arthur Andersen L.L.P., independent public accountants (the "Audited
         Financial Statements"), and (ii) the Company's unaudited consolidated
         balance sheet as of December 31, 1997 (the "Latest Balance Sheet"),
         and the related unaudited statements of income, stockholders' equity
         and cash flows for the twelve- month period then ended (together with
         the Latest Balance Sheet, the "Unaudited Financial Statements"),
         certified by the Company's Finance Manager (collectively, the
         "Financial Statements").  The Company has also delivered the Pro Forma
         Balance Sheet.  Except as shown in Schedule 3.1(d), the Financial
         Statements (i) represent actual bona fide transactions, (ii) have been
         prepared from the books and records of the Company and its
         consolidated Subsidiaries in conformity with GAAP applied on a basis
         consistent with preceding years throughout the periods involved,
         except that the Unaudited Financial Statements are not accompanied by
         notes or other textual disclosure required by GAAP, and (iii)
         accurately, completely and fairly present the Company's consolidated
         financial position as of the respective dates thereof and its
         consolidated results of operations and cash flows for the periods then
         ended, except that the Unaudited Financial Statements are subject to
         normal year-end adjustments consistent with past practice, which will
         not be material in the aggregate.  The Pro Forma Balance Sheet has
         been prepared from the books and records of the Company and its
         consolidated Subsidiaries in conformity with GAAP applied on a basis
         consistent with preceding years throughout the periods involved,
         subject to the footnotes and exceptions contained therein.  To the
         knowledge of Sellers and the Company, neither the Company nor any
         Subsidiary has any liability or obligation that would materially and
         adversely affect the business, assets, financial condition or results
         of operations of the Company and the Subsidiaries, whether accrued,
         absolute, contingent, or otherwise, except as set forth on the Latest
         Balance Sheet or on Schedule 3.1(d).  Except as disclosed on Schedule
         3.1(d), since the date of the Latest Balance Sheet, there has not been
         nor will there be any change in the assets, liabilities, financial
         condition, or operations of the Company or





                                      -6-
<PAGE>   14
         its Subsidiaries from that reflected in the Financial Statements,
         other than changes in the ordinary course of business, none of which
         individually or in the aggregate have had or will have a material
         adverse effect on such assets, liabilities, financial condition, or
         operations.  Without limiting any of the foregoing, since the date of
         the Latest Balance Sheet and until the Closing Date, except as
         disclosed on Schedule 3.1(d) the Company and its Subsidiaries have not
         and, except as specifically contemplated in Sections 4.10 and 5.1
         below, will not have:

                               (i)         incurred or become subject to, or
                 agreed to incur or become subject to, any obligation or
                 liability, absolute or contingent, except current liabilities
                 incurred in the ordinary course of business;

                              (ii)         mortgaged, pledged, or subjected to
                 any Encumbrance (or agreed to do so with respect to) any of

                 Company, any Subsidiary, or an affiliate of the Company or any
                 Subsidiary is a party, the benefits of which are enjoyed in
                 the Business or to which any of the assets of the Company or
                 any Subsidiary is subject;

                          (ii)    Schedule 3.1(f) hereto contains a complete
                 and correct list of the Company's and Subsidiaries' owned and

                 and correct list of all Permits relating to the development,

                 tax registrations).

         thereto) referred to in Schedule 3.1(f) hereto have been delivered to
         or made available for inspection by Buyer.  Except as shown on
         Schedule 3.1(f), all rights, licenses,  leases, registrations,
         applications, contracts, commitments, Permits and other arrangements
         by the Sellers, the Company or any Subsidiary referred to in Schedules

                                      -8-

         force and effect and valid and enforceable would not in the aggregate
         have an adverse effect on the assets of the Company or its
         Subsidiaries or on their respective results of operations.  Except as
         shown on Schedule 3.1(f), the Company, the Subsidiaries, and their
         respective affiliates are not in breach or default in the performance
         of any material obligation thereunder and to the best knowledge of the
         Sellers and the Company, no event has occurred or has failed to occur
         whereby any of the other parties thereto have been or will be released
         therefrom or will be entitled to refuse to perform thereunder.  Except
         as set forth in Schedule 3.1(f) hereto, there are no contracts,
         agreements, licenses, Permits, franchises or rights to which the
         Company or any of its Subsidiaries or affiliates is a party which are
         material to the ownership of any of the Company's assets, the assets
         of any Subsidiary, or to the conduct of the Business as conducted by
         the Company and its Subsidiaries.  Except as described on Schedule
         3.1(f) hereto, the Company and each Subsidiary has and will have

         authorizations, qualifications and orders of Governmental Entities
         required for the conduct of the business as presently conducted.

         attorney relating to or affecting the Company or any Subsidiary.
         Except as shown on Schedule 3.1(f), neither the Company nor any
         Subsidiary is a guarantor for or otherwise liable for any liability or
         obligation (including indebtedness of any other person).

                 (g)      Defects.  The buildings, plants, structures, Vessels,
         and equipment of the Company and the Subsidiaries are being
         transferred "as is, where is" with Seller's only obligation with
         respect thereto prior to Closing to continue to maintain same in
         accordance with past practices in the ordinary course of business.
         The building, plants, structures, equipment and Vessels of the Company
         and its Subsidiaries are sufficient for the continued conduct of the
         Company's and its Subsidiaries' businesses after the Closing in
         substantially the same manner as conducted prior to the Closing.

         receivable reflected on the Latest Balance Sheet or on the accounting
         records of the Company and its Subsidiaries as of the Closing Date
         (collectively, the "Accounts Receivable") represent or will represent
         valid obligations arising from sales actually made or services
         actually performed in the ordinary course of business.  Unless paid
         prior to the Closing Date, except as shown in Schedule 3.1(h), the
         Accounts Receivable are or will be as of the Closing Date current and
         collectible net of the respective reserve shown on the Balance Sheet
         or on the accounting records of the Company and its Subsidiaries as of
         the Closing Date (which reserves are adequate and calculated
         consistently with past practice and, in the case of the reserve as of
         the Closing Date, will not represent a greater percentage of the
         Accounts Receivable as of the Closing Date than the reserve reflected
         in the Latest Balance Sheet represented of the Accounts Receivables
         reflected therein and will not represent a material adverse change in
         the composition of such Accounts Receivable in terms of aging.
         Subject to such reserves, except as shown in Schedule 3.1(h), each of
         the Accounts Receivable either has been or will be collected in full,
         without any setoff.  Except as shown in Schedule 3.1(h), the
         inventories and work in progress reflected on the Latest Balance Sheet
         and those items of inventory constructed or acquired by the Company
         and the work performed by the Company after the date of the Latest
         Balance Sheet, except to the extent disposed of or billed since such
         date in the ordinary conduct of the business by the Company or its
         Subsidiaries, are, in the case of such inventory, in good,
         merchantable and usable condition, and, in the case





                                      -9-
<PAGE>   17
         of such work in progress, represent work completed in accordance with
         the requirements of any applicable contract, and, in each case, have
         been reflected on the books of the Company in accordance with GAAP.
         Except as set forth on Schedule 3.1(e) hereto, all such inventories
         and work in progress are owned by the Company or its Subsidiaries free
         and clear of any Encumbrances.

                 (i)      Legal Proceedings.  Except as described in Schedule
         3.1(i) hereto, (i) there is no litigation, proceeding, claim or
         governmental investigation pending or, to the knowledge of any of the
         Sellers or the Company, threatened seeking relief or damages which, if
         granted, would adversely affect the Company, any Subsidiary, any of
         their respective assets, or the ability of Buyer to use and operate
         the assets of the Company and the Subsidiaries or which would prevent
         the consummation of the transactions contemplated by this Agreement
         and (ii) neither the Sellers, the Company nor any Subsidiary has been
         charged with any violation of or, to the knowledge of either the
         Sellers or the Company, threatened with a charge or violation of, nor
         is either of the Sellers or the Company aware of any facts or
         circumstances that, if discovered by third parties, could give rise to
         a charge or a violation of, any provision of Applicable Law or
         regulation which charge or violation, if determined adversely to
         either the Sellers, the Company or any Subsidiary, would adversely
         affect the Business or the results of operations of the Company or its
         Subsidiaries or that might reasonably be expected to affect the right
         of Buyer to own the Stock or operate the Company's and Subsidiaries'
         Business after the Closing Date in substantially the manner in which
         it is currently operated.  None of the Company, any Subsidiary, or any
         director, officer, employee or agent of any of them has, directly or
         indirectly, paid or delivered any fee, commission or other sum of
         money or item of property however characterized to any broker, finder,
         agent, governmental official or other person, in any matter related to
         the Business of the Company or any Subsidiary, which the Company, any
         Subsidiary, or any such director, officer, employee or agent knows or
         has reason to believe to have been illegal under any Applicable Law.

                 Subsidiaries.  All premiums due and arising thereon have been
                 paid on a current basis and such policies are in full force
                 and effect.

                          (ii)    The Company maintains, with financially sound
                 and reputable insurers, insurance policies covering such
                 perils and in such amounts as are usually maintained on
                 vessels engaged in the same or a similar business as the
                 Vessels under blanket fleet policies with respect to vessels
                 of like size, character and marine activity as the Vessels;

         conduct of the Business as presently conducted; (ii) to the best
         knowledge of the Sellers and the Company, there is no basis for the

         as to comply with all Applicable Laws, rights of concession, licenses,
         know-how or other proprietary rights of others, the failure to comply
         with which would individually or in the aggregate have a material
         adverse effect on the Business, the Vessels or the results of
         operations of the Company or any Subsidiary.

         Subsidiaries have been prepared and maintained in accordance with good
         business practices and, where applicable, in conformity with GAAP and,
         to the best of Company's and Sellers' knowledge, in compliance with
         all Applicable Laws and other requirements.

                 (p)      Taxes.  Except as shown on Schedule 3.1(p), for the
         past five years, the Company and the Sellers have caused to be timely
         filed with appropriate federal, state, local, foreign, provincial and
         other Governmental Entities all Tax Returns required to be filed with
         respect to the Company, the Subsidiaries or the conduct of the
         Business and have paid, caused to be paid, or adequately reserved in
         the Financial Statements all Taxes due or claimed to be due from or
         with respect to such Tax Returns or which are or will become payable
         with respect to all periods prior to Closing.  Except as set forth on

         Business from any taxing authority. Except as shown on Schedule
         3.1(p), none of the Company or any Subsidiary has taken action which
         is not in accordance with past practice that could defer any liability
         for Taxes from any taxable period ending on or before the Closing Date
         to any taxable period ending after such date and neither of the
         Company or any Subsidiary has consented to the application of Section
         341(f) of the Code.

         terms and conditions of employment of any employee of the Company or
         any Subsidiary; no collective bargaining agent has been certified as a
         representative of any of the employees of the Company or any
         Subsidiary; and no representation campaign or election is now in
         progress with respect to any of the employees of the Company or any
         Subsidiary.  Except as shown on Schedule 3.1(r), neither the Sellers,
         the Company nor any Subsidiary has taken or failed to take any action
         that would cause Buyer to incur any liability in the event Buyer
         chooses to dismiss from its employment any of the Company's employees
         or any employee of any Subsidiary following the Closing.  Except as
         shown on Schedule 3.1(r), the Company and each Subsidiary has complied

                 all documents or instruments establishing or constituting any
                 related trust, annuity contract or other funding instrument)
                 to which the Company or any Subsidiary is (or ever has been) a
                 party or by which the Company or any Subsidiary is (or ever
                 has been) bound, including, without limitation, (1) any

                 arrangement or any plan, agreement or arrangement providing
                 for "fringe benefits" or perquisites to employees, officers,
                 directors or agents, including but not limited to benefits
                 relating to automobiles, clubs, vacation, child care,

                 of insurance, (3) any employment agreement, or (4) any other
                 "employee benefit plan" (within the meaning of Section 3(3) of
                 ERISA).

                              (ii)         The Sellers and the Company have
                 delivered to Buyer true, correct and complete copies of all
                 plan documents and/or contracts (including, where applicable,
                 any documents and/or instruments establishing or constituting
                 any related trust, annuity contract or funding instrument) and
                 summary plan descriptions with respect to the plans,

                 identified in Schedule 3.1(s) hereto that was required to file
                 an annual report for the plan year immediately preceding the
                 Closing Date.  Each of such Forms 5500 accurately reflects the
                 financial status of the plan to which it relates as of the
                 dates specified therein.  In addition, the Sellers and the
                 Company have provided Buyer with (a) true, correct and
                 complete copies of any and all written communications notices
                 or claims that the Sellers, the Company, or any Subsidiary
                 have received from the IRS, the Department of Labor and/or the
                 Pension Benefit Guaranty Corporation concerning any plan,
                 arrangement or agreement identified in Schedule 3.1(s) hereto
                 that give notice of possible imposition of a fine, penalty or
                 liability with respect to such plan, arrangement or agreement
                 and (b) true, correct and complete copies of any complaints,
                 petitions, claims or other notices of liability relating to
                 any such plan, arrangement or agreement that have been filed
                 by any other party.

                             (iii)         For each of the plans, agreements
                 and arrangements identified in Schedule 3.1(s) hereto, there
                 are no negotiations, demands or proposals that are pending or
                 have been made since the dates of the respective items
                 furnished pursuant to Section 3.1(s)(ii) hereto which concern
                 matters now covered, or that would be covered, by plans,
                 agreements or arrangements of the type described in this
                 Section.

                              (iv)         The Company, the Subsidiaries, and
                 each of the plans, agreements and arrangements identified in
                 Schedule 3.1(s) hereto are in full compliance with the
                 applicable provisions of the Code and ERISA, the regulations
                 and published authorities thereunder, and all other laws
                 applicable with respect to all such employee benefit plans,
                 agreements and arrangements.  The Sellers, the Company and the
                 Subsidiaries have performed all of their respective
                 obligations under all such plans, agreements and arrangements
                 including, but not limited to, the full payment when due of
                 all amounts required to be made as contributions thereto or
                 otherwise.  There are no actions, suits or claims (other than
                 routine claims for benefits) pending or threatened against
                 such plans or their assets, or arising out of such plans,
                 agreements or arrangements, and, to the best knowledge of the
                 Sellers and the Company, no facts exist which could give rise
                 to any such actions, suits or claims that might have a
                 material adverse effect on such plans, agreements or
                 arrangements.

                               (v)         Except as specified in Schedule
                 3.1(s) hereto, each of the plans, agreements or arrangements
                 can be terminated by the Company within a period of 30 days,
                 without payment of any additional compensation or amount or
                 the additional vesting or acceleration of any such benefits.

                              (vi)         With respect to each plan identified
                 in Schedule 3.1(s) hereto which is an "employee benefit plan"
                 (within the meaning of Section 3(3) of ERISA) or a "plan"
                 (within the meaning of Section 4975(e)(1) of the Code), no
                 transaction has occurred which is prohibited by Section 406 of
                 ERISA or which could give rise to a material liability under
                 Section 4975 of the Code or Sections 502(i) or 409 of ERISA.

                                        (4)     Welfare Benefit Plans.  All
                          group health plans of the Company and Subsidiaries

                          or former employees.

                                        (5)     Fines and Penalties.  There has
                          been no act or omission by the Company, any
                          Subsidiary, or the Sellers or any ERISA affiliate

                 (u)      Investment Representations.

                      (i)         Each Seller is acquiring the Pool Stock for
         his own account for investment and not with a view to, or for sale or
         other disposition in connection with, any distribution of all or any
         part thereof, except (a) pursuant to an applicable exemption under the
         Securities Act or (b) in an offering covered by a registration
         statement filed pursuant to the Securities Act.  In acquiring the Pool
         Stock, each Seller is not offering or selling, and will not offer or
         sell, for Pool in connection with any distribution of the Pool Stock
         and each Seller does not have a participation and will not participate
         in any such undertaking or in any underwriting of such an undertaking
         except in compliance with applicable federal and state securities
         laws.

                      (ii)        Each Seller acknowledges that he or his
         representatives have been furnished with substantially the same kind
         of information regarding Pool and its business, assets, results of
         operations and financial condition as would be contained in a
         registration statement prepared in connection with a public sale of
         the Pool Stock.  Each Seller further represents that he has had an
         opportunity to ask questions of and receive answers from Pool
         regarding Buyer and its business, assets, results of operations and
         financial condition and the terms and conditions of the issuance of
         the Pool Stock.  The foregoing, however, shall not limit or modify the
         representations and warranties of Buyer in Section 3, shall not limit
         the rights of a Seller prior to and in anticipation of any issuance of
         the Pool Stock pursuant hereto, and shall not limit the disclosure
         requirements of applicable federal and state securities laws.

                    (iii)         Each Seller acknowledges that he is able to
         fend for himself, can bear the economic risk of his investment in the
         Pool Stock, and has such knowledge and experience in financial and
         business matters that he is capable of evaluating the merits and risks
         of an investment in the Pool Stock and is an "accredited investor" as
         defined in Regulation D under the Securities Act.

                      (iv)        Each Seller understands that the Pool Stock,
         when issued to such Seller, will not have been registered pursuant to
         the Securities Act or any applicable state securities laws, that
         unless and until registered as contemplated by Section 4.12 the Buyer
         Stock will be characterized as "restricted securities" under federal
         securities laws, and that under such laws and applicable regulations
         the Pool Stock cannot be sold or otherwise disposed of without
         registration under the Securities Act or an exemption therefrom.  In
         this connection, each Seller represents that he is familiar with Rule
         144 promulgated under the Securities Act, as currently in effect, and

         statement on Form S-3 (the "Shelf Registration Statement") covering
         the shares of Pool Stock issued to the Sellers pursuant to this
         Agreement, excluding, however, the shares of Pool Stock delivered into

         faith, expressed by a resolution specifying the reason therefor, that
         the secondary offer and resale of Registered Pool Stock by the Sellers
         as contemplated by the foregoing paragraph (a), would materially and
         adversely affect a pending or proposed public offering of securities
         of Pool, an acquisition, merger, recapitalization, consolidation,

         anticipated period of suspension.  Pool shall promptly notify each of
         the Sellers of the expiration or earlier termination of such
         suspension.

                 (c)      Notwithstanding the provisions of paragraph (a), if
         Pool shall file a registration statement with respect to an offering
         by it through an underwriter or group of underwriters (an "Underwriter
         Registration Statement") of Pool Stock or securities convertible into
         or exchangeable or exercisable for Registered Pool Stock, and the
         managing underwriter or underwriters advise Pool that a sale or
         distribution of the Registered Pool Stock covered by the Shelf
         Registration Statement would adversely affect such offering, then upon
         written notice to each of the Sellers by or on behalf of such
         underwriters, the Sellers shall, to the extent not inconsistent with
         applicable law, suspend the distribution of any shares of Pool Stock
         pursuant to the Shelf Registration Statement or otherwise directly or
         indirectly through derivative transactions sell any Pool Stock during
         a period specified by or on behalf of such underwriters, which period
         shall not be greater than 10 days prior to or 90 days following the
         effective date of such Underwriter Registration Statement.  The period
         following the effective date of such Underwriter Registration
         Statement shall be subject to early termination by the managing
         underwriter or underwriters.  Following expiration or termination of
         any such suspension pursuant to this paragraph (c), no other
         suspension may be imposed for at least 90 days.

                 (d)      If, at any time prior to the first anniversary of the
         Closing Date, Pool proposes to register under the Securities Act any
         shares of Registered Pool Stock for sale by it pursuant to an
         underwritten public offering (except with respect to registration
         statements filed on Form S-4 or such other forms as shall be
         prescribed under the Securities Act for the same purposes as such
         form), it will at each such time, prior to the filing of any such
         registration statement, give written notice to the Sellers who then
         hold shares of Registered





                                      -24-
<PAGE>   32
         Pool Stock of its intention so to do and, upon the written request
         (which must specify the number of shares of Registered Pool Stock to
         participate in such underwritten offering) of any of the Sellers
         delivered to Pool within five days of receipt of  Pool's notice, Pool
         will use all reasonable best efforts to cause any Registered Pool
         Stock issued to such requesting Seller as to which registration shall
         have been so requested to be included in the shares to be covered by
         the registration statement proposed to be filed by Pool for sale by it
         in such offering, all to the extent requisite to permit the sale or
         other disposition (in accordance with the written request of the
         Sellers as aforesaid) of such Registered Pool Stock in such offering
         as have so requested such registration.  Nothing contained herein
         shall, however, limit Pool's right to cancel, postpone or withdraw any
         such proposed registration for any reason.

                 (e)      Any request by the Sellers pursuant to paragraph (a)
         to register Registered Pool Stock for sale in the underwriting shall
         be on the same terms and conditions as the shares of Registered Pool
         Stock to be registered, if any, and sold through underwriters under
         such registration; provided, however, that as a condition to such
         inclusion the requesting Sellers shall execute an underwriting
         agreement acceptable to the underwriters and, if requested, a custody
         agreement having such customary terms as the underwriters shall
         request, including indemnification, and if the managing underwriter
         determines and advises in writing that the inclusion in the
         underwriting of all Registered Pool Stock proposed to be included by
         the requesting Sellers and any other shares of Registered Pool Stock
         sought to be registered by any other shareholder of Pool exercising
         rights comparable to those of the Seller (the "Other Common Stock")
         would, in its reasonable and good faith judgment, interfere with the
         successful marketing of the securities proposed to be registered for
         underwriting by Pool or by any holder of Registered Pool Stock having
         the right to require Pool to file a registration statement to register
         such Registered Pool Stock, then the number of shares of Registered
         Pool Stock and Other Common Stock requesting such registration and
         inclusion in the underwriting and may, in the determination of such
         managing underwriter and consistent with pro rata reduction, be
         reduced to zero.

                 (f)      Following the filing of the Shelf Registration
         Statement, Pool will:

                          (i)     use reasonable efforts to cause the Shelf
                 Registration Statement to become effective as expeditiously as
                 reasonably practicable and remain effective until the first
                 anniversary of the Closing Date or such shorter period of time
                 until the transfer or sale of all Registered Pool Stock so
                 registered has been completed;

                          (ii)    as expeditiously as reasonably practicable,
                 prepare and file with the Commission such amendments and
                 supplements to the Shelf Registration Statement and the
                 prospectus used in connection therewith as may be necessary to
                 keep the Shelf Registration Statement effective and to comply
                 with the provisions of the Securities Act with respect to the
                 disposition of such Registered Pool Stock covered by the Shelf
                 Registration Statement in accordance with the intended method
                 of distribution set forth in the Shelf Registration Statement;

                          (iii)   as expeditiously as reasonably practicable,
                 furnish to each of the Sellers selling Registered Pool Stock
                 registered, or to be registered under the





                                      -25-

                 Securities Act, such number of copies of prospectuses and
                 preliminary prospectuses in conformity with the requirements
                 of the Securities Act, and such other documents as such Seller
                 may reasonably request, in order to facilitate the public sale
                 or other disposition of such Registered Pool Stock owned by
                 such Seller; provided, however, that the obligation of Pool to
                 deliver copies of prospectuses or preliminary prospectuses to
                 such Sellers shall be subject to the receipt by Pool of
                 reasonable assurances from such Sellers that they will comply
                 with the applicable provisions of the Securities Act and of
                 such other securities laws as may be applicable in connection
                 with any use by it of any prospectuses or preliminary
                 prospectuses;

                          (iv)    as expeditiously as practicable, use its best
                 efforts to register or qualify Registered Pool Stock covered
                 by such registration statement under such other securities
                 laws of such United States jurisdictions as the Sellers making
                 such request shall reasonably request (considering the nature
                 and size of the offering) and do any and all other acts and
                 things which may be necessary or desirable to enable the
                 Sellers making such request to consummate the public sale or
                 other disposition in such jurisdictions of Registered Pool
                 Stock owned by such Sellers; provided, however, that Pool
                 shall not be required to qualify to transact business as a
                 foreign corporation in any jurisdiction in which it would
                 otherwise not be required to be so qualified or to take any
                 action which would subject it to general service of process or
                 to taxation in any jurisdiction in which it is not then so
                 subject; and

                          (v)     bear all Registration Expenses (as defined
                 below) in connection with the Shelf Registration Statement;
                 provided, however, that all Selling Expenses (as defined
                 below) of Registered Pool Stock held by the Sellers and all
                 fees and disbursements of counsel for the Sellers in
                 connection with the Shelf Registration Statement pursuant to
                 this Section 4.12 shall be borne by such Sellers pro rata in
                 proportion to the number of shares of Registered Pool Stock
                 covered thereby being sold or in such proportion as they may
                 agree.  All (i) registration and filing fees; (ii) printing
                 expenses; (iii) fees and disbursements of counsel for Pool;
                 (iv) blue sky fees and expenses; and (v) fees and expenses of
                 accountants for Pool are herein referred to as "Registration
                 Expenses".  All underwriting fees and discounts and brokerage
                 and selling commissions and fees and expenses of the counsel
                 for the Sellers and any underwriter's counsel applicable to
                 the sales in connection with the Shelf Registration Statement
                 are herein referred to as "Selling Expenses".

                 (g)      Pool will indemnify and hold harmless each Seller,
         with respect to which registration or qualification of Registered Pool
         Stock has been effected pursuant to this Section 4.12 against all
         claims, losses, damages, and liabilities, joint or several (or actions
         in respect thereof), arising out of or based upon any untrue statement
         (or alleged untrue statement) of a material fact contained in the
         Shelf Registration Statement, prospectus, or offering circular, or in
         any document incorporated by reference in any of the foregoing, or
         arising out of or based upon any omission (or alleged omission) to
         state therein a material fact required to be stated therein or
         necessary to make the statements therein not misleading, or any
         violation by Pool of any rule or regulation promulgated under the
         Securities Act applicable to Pool and relating to action or inaction
         required of Pool in connection with any





                                      -26-
<PAGE>   34
         such registration or qualification, and will promptly reimburse each
         such Seller, each of such Seller's officers,  directors, partners, or
         members, as the case may be, and each person controlling such Seller,
         for any legal and any other expenses reasonably incurred in connection
         with investigating or defending any such claims, loss, damage,
         liability or action; provided, however, that Pool  will not be liable
         in any such case to the extent that any such claim, loss, damage,
         liability or expense arises out of or is based upon any untrue
         statement or omission based upon written information furnished to Pool
         by such Seller specifically for inclusion in the Shelf Registration
         Statement, prospectus or offering circular.  The obligations of Pool
         under the foregoing indemnity agreement shall survive the completion
         of the offering of Registered Pool Stock under the Shelf Registration
         Statement provided for in this Section 4.12.

                 (h)      Each Seller with respect to which registration or
         qualification of Registered Pool Stock has been effected pursuant to
         this Section 4.12 will indemnify and hold harmless Pool, each of
         Pool's officers, directors, and each person controlling Pool, against
         all claims, losses, damages, and liabilities, joint or several (or
         actions in respect thereof), arising out of or based upon any untrue
         statement (or alleged untrue statement) of a material fact contained
         in the Shelf Registration Statement, prospectus, or offering circular,
         or in any document incorporated by reference in any of the foregoing,
         or arising out of or based upon any omission (or alleged omission) to
         state therein a material fact required to be stated therein or
         necessary to make the statements therein not misleading, or any
         violation by such Seller of any rule or regulation promulgated under
         the Securities Act applicable to such Seller and relating to action or
         inaction required of such Seller in connection with any such
         registration or qualification, and will promptly reimburse Pool, each
         of Pool's officers, directors, and each person controlling Parent, for
         any legal and any other expenses reasonably incurred in connection
         with investigating or defending any such claims, loss, damage,
         liability or action; provided, however, that such Seller will not be
         liable in any such case to the extent that any such claim, loss,
         damage, liability or expense does not arise out of or is not based
         upon any untrue statement or omission based upon written information
         furnished by such Seller specifically for inclusion in the Shelf
         Registration Statement, prospectus or offering circular.  The
         obligations of Sellers under the foregoing indemnity agreement shall
         survive the completion of the offering of Registered Pool Stock under
         the Shelf Registration Statement provided for in this Section 4.12.

                 (i)      If Rule 144 as promulgated under the Securities Act
         or any successor or similar rule or statute shall permit the sale by a
         Seller at any time over a period of 90 consecutive days of all the
         shares of Pool Stock received by the Sellers in compliance with the
         provisions thereof, then the rights of the Sellers as to registration
         provided for in this Section 4.12 with respect to all of that Seller's
         portion of the Pool Stock shall terminate immediately.

         into) or renew any material agreements or other commitments extending
         a substantial term beyond the Closing Date or take any action which is
         not in the ordinary course of business, except for the transactions
         otherwise contemplated herein, without the prior written approval of
         Buyer.

                 (i)      Material Adverse Change.  There shall have been no

                 title for each Vessel dated immediately prior to the Closing
                 Date evidencing the Company's ownership of the Vessel free and
                 clear of all Encumbrances, except as set forth in Section 3.1

         representations and warranties of Buyer contained herein or in any
         certificate or document delivered to the Sellers pursuant hereto shall
         be true and correct on and as of the Closing Date, with the same force
         and effect as though such representations and warranties had been made
         on and as of the Closing Date, except as contemplated or permitted by
         this Agreement.

                 (b)      Performance of Agreements.  Buyer shall have

                 (e)      Material Adverse Change. There shall have been no
         material adverse change in the financial or business condition of
         Buyer or Pool from September 30, 1997 until the Closing Date.

6.       Termination.

         6.1     General.  This Agreement may be terminated and the
transactions contemplated herein may be abandoned (a) by mutual consent of
Buyer and the Sellers or (b) by any party by notice to the other parties in the
event that the Closing Date shall not have occurred on or before April 30,
1998; provided, however, that if the Closing Date shall not have occurred on or
before such date due to a breach of this Agreement by one of the parties or an
affiliate of such party, that party may not terminate this Agreement.

         6.2     No Liabilities in Event of Termination.  In the event of any
termination of this Agreement as provided above, this Agreement shall forthwith
become wholly void and of no further force or effect, except that the
provisions of Sections 4.9, 8.6, 9.1, 9.11, 9.12 and 9.13 hereof shall remain
in full force and effect, and provided that nothing contained herein shall
release any party from liability hereinafter provided in this paragraph for any
failure to comply with any provision, covenant or agreement contained herein.

         In the event either party (the "Breaching Party") fails to close the
transaction as contemplated by this Agreement notwithstanding that all of the
conditions to its obligation to close have been met, the other party (the
"Non-Breaching Party") shall be entitled to payment of liquidated damages in
the amount of $10,000,000 which shall be payable by the Breaching Party on May
1, 1998; provided, however, if Sellers fail to close as a result of a breach of
Section 4.8 hereof, Sellers and Company shall be jointly and severally
obligated to pay Buyer the sum of $10,000,000 as a fee and liquidated damages.
The aforesaid payment shall be the sole and exclusive remedy of the
Non-Breaching Party for damages for failure to close this transaction.

7.       Covenants; Action Subsequent to Closing.

         7.1     Use of Names.  After the date hereof, the Sellers each agrees
that neither they, nor any of their affiliates shall use the names, trademarks,
slogans, trade names, logos or labels of the Company or any Subsidiary.

8.       Indemnification.

         8.1     Indemnification by the Sellers.  Subject to the provisions of
this Section 8, the Sellers, jointly and severally, (without any right of
contribution from the Company) shall protect, indemnify and hold harmless
Buyer, each officer, director and agent of Buyer and each person who controls
Buyer in respect of any losses, claims, damages, liabilities, deficiencies,
delinquencies, defaults, assessments, fees, penalties or related costs or
expenses, including, but not limited to, court costs and attorneys', and
accountants' fees and disbursements, and any federal, state or local income or
franchise taxes payable in respect of the receipt of cash or money in discharge
of the foregoing, but reduced by any net amount paid to Buyer on account of
such loss by any insurance policies





                                      -31-

(collectively referred to herein as "Damages") to which Buyer may become
subject if such Damages arise out of or are based upon the breach of any of the
representations and warranties (whether such breach occurred as of the date of
execution of this Agreement or as of the Closing Date), covenants or agreements
made by the Sellers or the Company in this Agreement, including the Exhibits
and Schedules hereto, or in any certificate or instrument delivered by or on
behalf of the Sellers or the Company pursuant to this Agreement.

         8.2     Indemnification by Buyer.  Subject to the provisions of this
Section 8, Buyer shall protect, indemnify and hold harmless the Sellers, in
respect of any Damages to which the Sellers may become subject if such Damages
arise out of or are based upon the breach of any of the representations,
warranties, covenants or agreements made by Buyer in this Agreement, including
the Exhibits and Schedules hereto, or in any certificate delivered by or on
behalf of Buyer pursuant to this Agreement.  The aggregate liability of Buyer
under this Section 8.2, and any other provision of this Agreement, any other
contract, any theory in tort or any other theory in law or equity, shall not
exceed $20,000,000.

         8.3     Monetary Limit on Indemnification Liability.

                 (a)      Notwithstanding any other provisions to the contrary
         in this Agreement, the aggregate total liability under Section 8.1(a)
         of this Agreement, any other provision of this Agreement, any other
         Contract, any theory in tort or any theory of law of the Sellers shall
         be limited to the lesser of (i) $20,000,000 or (ii) the value of the
         Pool Stock held pursuant to the Escrow Agreement (determined pursuant
         to the terms and conditions of the Escrow Agreement) (except with
         respect to Damages relating to title to the Shares the liability for
         which shall not be so limited) with Buyer and Pool waiving and
         releasing Sellers from any and all claims (except with respect to
         Damages relating to title to the Shares) exceeding said limit in the
         aggregate.  Buyer and Pool waive release and discharge Sellers from
         any liability hereunder in excess of the limit contained in this
         Section 8.3(a).

                 (b)      In order to avoid or diminish disputes between
         Sellers and Buyer with respect to the indemnity obligations set forth
         herein, as limited by Section 8.3(a) above, 8.3(c) and 8.4, below, the
         parties agree that Sellers shall have no liability to either Buyer or
         Pool with respect to any breach of the obligations set forth in
         Section 8.1, this Agreement, any other contract, any theory of tort,
         or any other theory of law, until $500,000 in aggregate liability for
         Damages or under any theory of tort, or any theory is reached, with
         Sellers only being responsible for amounts exceeding $500,000 in the
         aggregate subject to the limits of Section 8.3(a) above.

         8.4     Indemnification Procedures.  The obligations and liabilities
of each indemnifying party hereunder with respect to claims resulting from the
assertion of liability by the other party or third parties shall be subject to
the following terms and conditions:

                 (a)      If any person shall notify an indemnified party (the
         "Indemnified Party") with respect to any matter which may give rise to
         a claim for indemnification (a "Claim") against Buyer or the Sellers
         (the "Indemnifying Party") under this Section 8, then the Indemnified
         Party shall promptly notify each Indemnifying Party thereof in
         writing.

<PAGE>   40
                 (b)      Any Indemnifying Party will have the right to defend
         the Indemnified Party against the Claim with counsel of its choice
         reasonably satisfactory to the Indemnified Party so long as (i) the
         Indemnifying Party notifies the Indemnified Party in writing within 15
         days after the Indemnified Party has given notice of the Claim that
         the Indemnifying Party will indemnify the Indemnified Party from and
         against the entirety (subject to any limitations contained in Section
         8) of any Damages the Indemnified Party may suffer resulting from,
         arising out of, relating to, in the nature of or caused by the Claim,
         (ii) the Indemnifying Party provides the Indemnified Party with
         evidence reasonably acceptable to the Indemnified Party that the
         Indemnifying Party will have the financial resources to defend against
         the Claim and fulfill its indemnification obligations hereunder, (iii)
         the Claim involves only money damages and does not seek an injunction
         or other equitable relief, (iv) settlement of, or an adverse judgment
         with respect to, the Claim is not, in the good faith judgment of the
         Indemnifying Party, likely to establish a precedental custom or
         practice materially adverse to the continuing business interests of
         the Indemnified Party, and (v) the Indemnifying Party conducts the
         defense of the Claim actively and diligently and in good faith.

                 (c)      So long as the Indemnifying Party is conducting the
         defense of the Claim in accordance with Section 8.4(b) above, (i) the
         Indemnified Party may retain separate co-counsel at its sole cost and
         expense and participate in the defense of the Claim, (ii) the
         Indemnified Party will not consent to the entry of any judgment or
         enter into any settlement with respect to the Claim without the prior
         written consent of the Indemnifying Party (not to be withheld
         unreasonably), and (iii) the Indemnifying Party will not consent to
         the entry of any judgment or enter into any settlement with respect to
         the Claim without the prior written consent of the Indemnified Party
         (not to be withheld unreasonably).

                 (d)      In the event any of the conditions in Section 8.4(b)
         above is or becomes unsatisfied, however, (i) the Indemnified Party
         may defend against, and consent to the entry of any judgment or enter
         into any settlement with respect to, the Claim in any manner it
         reasonably may deem appropriate (and the Indemnified Party need not
         consult with, or obtain any consent from, any Indemnifying Party in
         connection therewith), (ii) the Indemnifying Party will remain
         responsible for any damages the Indemnified Party may suffer resulting
         from, arising out of, relating to, in the nature of, or caused by the
         Claim to the fullest extent provided in this Section 8.

         8.5     Time Limits on Liability.  Anything contained in this
Agreement to the contrary notwithstanding, the indemnity liability of any party
for indemnity shall only extend to matters for which a bona fide claim has been
asserted by written notice of such claim delivered to the Indemnifying Party on
or before two (2) years from the Closing Date except for (i) breaches of
representations with respect to title to the Shares, authority, and finders
fees which will survive indefinitely, (ii) breaches of representations with
respect to environmental matters and Jones Act liability which will survive for
three (3) years, and (iii) breaches of representations with respect to taxes
and ERISA which will survive for statutory limitation periods, including any
extensions or waivers thereof.  Buyer and Seller each waive and release any
claim for indemnity hereunder if notice is not given hereunder on or before the
expiration of the periods provided herein.

Gonsoulin as their representative  (the "Seller Representative"), who shall
have full power and authority to make all decisions relating to the Statement
provided in Section 2.3 and the defense and/or settlement of any claims for
which the Sellers may be required to so indemnify the Buyer (and vice versa)
and to take such other actions (and any other actions reasonably related or
ancillary thereto) provided herein to be taken by the Seller Representative.
If the Seller Representative shall die, become totally incapacitated or resign
from such position, the remaining Sellers shall select another member from
among the selling group (or their heirs, executors, administrators or personal
representatives) to fill such vacancy.  All decisions and actions by the Seller
Representative, including, without limitation, any agreement between the Seller
Representative and the Buyer relating to the determination of Adjusted Profit

required to so indemnify Buyer, any decision, action or agreement to be made or
taken under the Escrow Agreement, any amendment to this Agreement or the Escrow
Agreement or any other action provided herein to be taken by the Seller
Representative, shall be binding upon all of the Sellers, and no Seller shall
have the right to object, dissent, protest or otherwise contest the same.  By
their execution of this Agreement, the Sellers shall be deemed to have agreed
that (i) the provisions of this Section 8.6 are independent and  severable, are
irrevocable and coupled with an interest and shall be enforceable
notwithstanding any rights or remedies that any Seller may have in connection
with the transactions contemplated by this Agreement, (ii) the remedy at law
for any breach of the provisions of this Section 8.6 would be inadequate, (iii)
the Buyer shall be entitled to temporary and permanent injunctive relief
without the necessity of proving damages if it brings an action to enforce the
provisions of this Section 8.6, (iv) the provisions of this Section 8.6 shall
be binding upon the heirs, executors, administrators, personal representatives
and successors of each Seller and (v) any references in this Agreement to a
Seller or Sellers shall mean and include the successors to the Sellers' rights
hereunder, whether pursuant to testamentary disposition, the laws of descent
and distribution or otherwise.  All fees and expenses incurred by the Seller
Representative shall be paid by the Sellers.

available to Sellers.

communications which are required or may be given under this Agreement shall be

Schedules hereto) constitutes the entire agreement between the parties hereto
and supersedes all prior agreements and understandings, oral and written,
between the parties hereto with respect to the subject matter hereof.

         9.4     Binding Effect; Benefit.  This Agreement shall inure to the
benefit of and be binding upon the parties hereto and their respective

than the parties hereto or their respective heirs, personal representatives,
successors and assigns, any rights, remedies, obligations or liabilities under
or by reason of this Agreement.

         9.5     Assignability.  This Agreement shall not be assignable by the
Sellers without the prior written consent of Buyer or by Buyer without the

Sellers, so long as Buyer and Pool guarantee the full performance of the
obligations set forth herein.

         9.6     Amendment; Waiver.  This Agreement may be amended,

charges that are contracted for, charged, reserved, received, collected,
applied or paid which constitute interest under Applicable Law) payable
hereunder any amount in excess of the maximum nonusurious contract rate of
interest allowed from time to time by Applicable Law, and in the event any of
the parties hereto ever charges, reserves, receives, collects or applies, as
interest, any such excess, at the option of the payor of such interest, such
amount shall be deemed a partial prepayment of the amount payable hereunder or
promptly refunded to the payor of such interest.

         9.8     Section Headings; Index.  The section headings contained in
this Agreement are for reference purposes only and shall not affect the meaning

         9.12    Dispute Resolution.  Any dispute, difference or question
("Dispute") between Buyer and the Sellers ("Disputing Parties"), shall be
resolved in accordance with the following dispute resolution procedures:

                 (a)      Good Faith Negotiations.  The Disputing Parties shall
         endeavor, in good faith, to resolve the Dispute through negotiations.
         If the Parties fail to resolve the Dispute within a reasonable time,
         each Party shall nominate a senior officer or officers of its
         management to meet at any mutually agreed location to resolve the
         Dispute.

                 (b)      Mediation.  In the event that the negotiations do not
         result in a mutually acceptable resolution, either Disputing Party may
         require that the Dispute shall be referred to mediation in Houston,
         Texas.  One mediator shall be appointed by the agreement of the
         Parties.   The mediator shall be suitably qualified person having no
         direct or personal interest in the outcome of the Dispute.  Mediation
         shall be held within thirty (30) days of referral to mediation.  In
         the event the Disputing Parties are unable to agree on a mediator, the
         Parties agree to the appointment of a mediator pursuant to the
         Commercial Mediation Rules of the American Arbitration Association.

                 (c)      Arbitration.  In the event the Parties are
         unsuccessful in their mediation of the Dispute, or if there is any
         Dispute about the scope of or the compliance by any Party with the
         provisions of Section 9.12, either Disputing Party may request that
         the Dispute be settled by arbitration by an arbitrator mutually
         acceptable to the Disputing Parties in an arbitration proceeding
         conducted in the City of Houston, Texas in accordance with the rules
         existing at the date hereof of the American Arbitration Association.
         If the Disputing Parties hereto cannot agree on an arbitrator within
         ten (10) business days of the initiation of the arbitration
         proceeding, an arbitrator shall be selected for the Disputing Parties
         by the American Arbitration Association.  The Disputing Parties shall
         use their reasonable best efforts to have the arbitral proceeding
         concluded and a judgment rendered by the arbitrator within forty (40)
         business days of the initiation of the arbitration proceeding.  The
         decision of such arbitrator shall be final, and judgment upon the
         award rendered by the arbitration may be entered in any court having
         jurisdiction thereof, and the costs (including, without limitation,
         reasonable fees and expenses of counsel and experts for the Disputing
         Parties) of such arbitration (including the costs to enforce or
         preserve the rights awarded in the arbitration) shall be borne by the
         Disputing Party whom the decision of the arbitrator is against.  If
         the decision of the arbitrator is not clearly against one of the
         disputing Parties or the decision of the arbitrator is against more
         than one Disputing Party on one or more issues, the costs of such
         arbitration shall be borne equally by the Disputing Parties.
         Notwithstanding the foregoing, Buyer may apply to any court of
         competent jurisdiction for injunctive relief under Sections 7.1 or 8.6
         without breach of this Section 9.12 and this Section 9.12 shall be of
         no force and effect with respect to such applicant for injunctive
         relief only.

         9.13    Confidentiality.  In the event the Closing does not occur on
or before April 30, 1998, Pool and Buyer shall immediately return all copies of
Sea Mar documents and any abstracts, summaries, notes or other documents
relating thereto.  Further, Pool and Buyer acknowledge that Sea Mar has a
legitimate and continuing proprietary interest in the protection of its
confidential





                                      -37-
<PAGE>   45
information and that Sea Mar has invested substantial sums to develop, maintain
and protect that confidential information.  Accordingly, in the event the
transaction contemplated by the Stock Purchase Agreement is not closed in
accordance with the terms set forth therein, Pool and Buyer agree that they
shall keep secret, confidential, in strictest confidence, and shall not use for
the benefit of themselves or others, any information provided by or related to
Sea Mar and its business, including without limitation, financial information,
trade secrets, customer lists, employment lists, details of client or
consulting contracts, pricing policies, operational methods, marketing plans or

necessary for the holder hereof, in order to enforce payment of this Note, to
first institute or exhaust such
<PAGE>   54


holder's remedies against the Maker or any other party liable therefor or
against any security for this Note.  No delay on the part of the Payee in
exercising any power or right under this Note shall operate as a waiver of such
power or right, nor shall any single or partial exercise of any power of right
preclude further exercise of that power or right.

         All agreements between the Maker and the holder hereof, whether now
existing or hereafter arising and whether written or oral, are hereby expressly
limited so that in no contingency or event whatsoever, whether by reason of
acceleration of the maturity hereof, or otherwise, shall the amount paid, or
agreed to be paid, to the holder hereof for the use, forbearance or detention
of the funds advanced pursuant to this Note, or otherwise, or for the payment
or performance of any covenant or obligation contained herein or in any other
document or instrument evidencing, securing or pertaining to this Note exceed
the maximum amount permissible under applicable law.  If from any circumstances
whatsoever fulfillment of any provision hereof or any other document or
instrument exceeds the maximum amount of interest prescribed by law, then ipso
facto, the obligation to be fulfilled shall be reduced to the limit of such
validity, and if from any such circumstances the holder hereof shall ever
receive anything of value deemed interest by applicable law, which would exceed
interest at the highest lawful rate, such amount which would be excessive
interest shall be applied to the reduction of the unpaid principal balance of
this Note or on account of any other principal indebtedness of the Maker to the
holder hereof, and not to the payment of interest, or if such excessive
interest exceeds the unpaid principal balance of this Note and such other
indebtedness, such excess shall be refunded to the Maker.  All sums paid, or
agreed to be paid, by the Maker for the use, forbearance or detention of the
indebtedness of the Maker to the holder of this Note shall, to the extent
permitted by applicable law, be amortized, prorated, allocated and spread
throughout the full term of such indebtedness until payment in full so that the
actual rate of interest on account of such indebtedness is uniform throughout
the term hereof.  The terms and provisions of this paragraph shall control and
supersede every other provision of all agreements between the Maker and the
holder hereof.

         This Note shall be governed by and construed in accordance with the
laws of the State of Texas.

         All references to the Maker herein shall, and shall be deemed to,
include its successors and assigns, and all covenants, stipulations, promises
and agreements contained herein by or on behalf of the Maker shall be binding
upon its successors and assigns, whether so expressed or not.

                                ESCROW AGREEMENT


         THIS ESCROW AGREEMENT (as the same may be amended or modified from
time to time and including any and all written instructions given to "Escrow
Agent" (hereinafter defined) pursuant hereto, this "Escrow Agreement") is made
and entered into as of March __, 1998 by and among Pool Company, a Texas
corporation ("Buyer"), and Al A. Gonsoulin ("Representative") and Gonsoulin
Enterprises, Inc. (Al Gonsoulin and Gonsoulin Enterprises, Inc. sometimes
collectively referred to as the "Sellers," and Buyer together with the Sellers,
sometimes referred to collectively as the "Other Parties"), and Bank One Texas
N.A., a national banking association with its principal offices in Houston,
Harris County, Texas (the "Bank").


                             W I T N E S S E T H :

         WHEREAS, Buyer, Pool Energy Services Co. ("Pool"), Sea Mar, Inc. and
the Sellers have entered into that certain Stock Purchase Agreement (the
"Agreement") of even date herewith, relating to the purchase by Buyer from the
Sellers of all of the common stock of Sea Mar, Inc.; and

         WHEREAS, pursuant to the Agreement Pool is obligated to deposit
769,231 shares of Pool common stock ("Escrow Shares") received by Sellers as
part of the purchase price in escrow as security for Sellers' indemnity
obligations under the Agreement; and

         WHEREAS, Buyer and the Sellers have requested Bank to act in the
capacity of escrow agent under this Escrow Agreement, and Bank, subject to the
terms and conditions hereof, has agreed so to do.

         NOW, THEREFORE, in consideration of the premises and mutual covenants
and agreements contained herein, the parties hereto hereby agree as follows:

         1.      Appointment of Escrow Agent.  Each of Buyer and the Sellers
hereby appoints the Bank as the escrow agent under this Escrow Agreement (the
Bank in such capacity, the "Escrow Agent"), and Escrow Agent hereby accepts
such appointment.

         2.      Escrow Fund and Modifications to the Escrow Fund.  The parties
hereby acknowledge that on the date hereof, Buyer has delivered, or caused to
be delivered, to the Escrow Agent, to be held by it pursuant to the terms
hereof, the Escrow Shares, which are evidenced by a certificate or certificates
accompanied by stock powers executed by the Representative, as record holder of
the Escrow Shares, assigning such shares in blank.  The parties acknowledge
that the Escrow Shares are owned beneficially by the Sellers in the amounts set
forth on Schedule A hereto.  The Escrow Shares and any other property of any
nature received therefor, shall be held by the Escrow Agent pursuant to the
terms and conditions of this Agreement and shall constitute and be referred to
collectively as the "Escrow Fund."  After one
<PAGE>   57


year from date of this Escrow Agreement, the Representative may, at its sole
option, direct that all or any portion of the Escrow Shares be sold subject to
the requirements of applicable securities laws.  If, at that time or at any
time thereafter, the value of the Escrow Fund exceeds $20,000,000, the
Representative can direct that such excess be distributed in cash to Sellers
based upon their pro rata interest as shown on Schedule A hereto.  All
remaining cash in the Escrow Fund shall be invested by the Escrow Agent as the
Representative directs the Escrow Agent in writing in U.S.  government and
agency obligations, in certificates of deposit issued by, and interest bearing
deposit accounts, checking accounts or money market accounts of, the Escrow
Agent or in a mutual fund registered under the Investment Company Act of 1940,
the principal of which is invested solely in U.S. government and agency
obligations.

         3.      Dividends and Voting Rights.  The Sellers shall receive all
cash dividends paid with respect to the Escrow Shares.  Stock dividends or any
other non-cash distributions with respect to the Escrow Shares payable in
equity securities of Pool shall be deposited in the Escrow Fund, and shall be
considered to be Escrow Shares for all purposes of this Agreement, subject to
the rights of Representative set forth in Section 2 above.  The Representative,
as directed by the Sellers as to shares beneficially owned by them, shall have
the full right to vote the Escrow Shares unless and until they are delivered to
Buyer or Sellers pursuant to the terms of this Agreement.  For tax reporting
and withholding purposes, all dividends and other income with respect to the
Escrow Fund shall be allocated as the Representative shall direct in writing
or, in the absence of any such direction, to the escrow account created by this
Agreement, in which event the Escrow Agent shall at the expense of the
Representative file all necessary tax returns and pay any tax from the Escrow
Fund.

         4.      Application of the Escrow Fund to Satisfy Claims of Buyer.
The Escrow Agent is authorized and directed to draw upon the Escrow Fund, and
to deliver to Buyer that portion of the Escrow Shares as provided by this
Section 4, upon fulfillment of the following conditions:

                 (a)     The Escrow Agent shall have received from Buyer (i) a
         certificate to the following effect:

                 "Pursuant to the terms of the Stock Purchase Agreement, (the
         "Agreement") dated February 10, 1998, by and among Pool Company
         ("Buyer"), Pool Energy Services Co., Inc., Sea Mar, Inc. and the
         Sellers as defined therein, Buyer has incurred indemnifiable Losses
         (as defined in the Agreement) of $_________ [the amount which Buyer
         reasonably believes in good faith to be owing shall be inserted] (the
         "Indemnifiable Amount") relating to __________ [Buyer shall insert in
         reasonable detail the matter giving rise to the indemnifiable Losses,
         the basis for a claim that such matters constitute indemnifiable
         Losses, the manner in which the amount of indemnifiable Losses have
         been calculated and provide supporting documentation of such
         Indemnifiable Losses] which is due and owing, and you are to draw upon
         the Escrow Fund held by you, and deliver to Buyer, unless directed by
         Representative otherwise, cash (to the extent any cash or cash
         equivalent is held in the Escrow Fund, and the fewest number of




                                      2
<PAGE>   58
         Escrow Shares representing Market Value which is, with such cash so
         delivered, equal to the Indemnifiable Amount.  A copy of this
         statement has been given to the Representative in the manner specified
         in Section 15 of the Escrow Agreement pursuant to which you are
         acting."

and along with such certificate the Escrow Agent shall have received from
Buyer, (ii) a postal receipt evidencing the delivery by Buyer of a copy of such
certificate to the Representative in accordance with Section 15 hereof, or a
written receipt executed by the Representative evidencing such delivery.  For
purposes hereof, "Market Value" shall mean the Closing Price as that term is
defined in the Stock Purchase Agreement; and.

         (b)     Any one of the following three events ("Operative Events")
shall have occurred.

                 (i)      ten (10)  business days shall have elapsed between
         the date on which the Escrow Agent shall have received the certificate
         and evidence of delivery provided in Section 4(a)(i) and (ii) and the
         Escrow Agent shall not have received any letter or other document from
         the Representative protesting or otherwise disputing, challenging or
         disagreeing with any assertion contained in the certificate; or

                 (ii)     the Escrow Agent shall have received a certificate
         signed by Buyer and the Representative fixing and determining the
         amount of indemnifiable Losses of Buyer and the amount of the Escrow
         Fund (cash and/or Escrowed Shares) to be delivered and paid to Buyer
         in respect thereof; or

                 (iii)    the Escrow Agent shall have received a final arbitral
         order or final arbitral award which states on its face that it is
         rendered pursuant to the provisions of Section 9.12(c) of the Stock
         Purchase Agreement, to deliver an amount of the Escrow Fund to Buyer,
         which order or award shall override any notice from Buyer received
         pursuant to Section 4(a)(i) and any notice or other document from the
         Representative received pursuant to Section 4(b)(i) above.

         Upon fulfillment of such conditions, the Escrow Agent shall, within
five (5) business days, but no sooner than within two (2) business days (the
"Election Date"), of the last such event of fulfillment, deliver to Buyer that
portion of the Escrow Fund to which Buyer is entitled as determined in
accordance with the provisions of this Agreement; provided, however, that if
new certificates must be issued to represent the number of Escrow Shares to be
delivered to Buyer, the Escrow Agent shall deliver the appropriate certificate
or certificates representing the Escrow Shares to the transfer agent of the
Pool common stock (the "Transfer Agent") so that the Transfer Agent may issue
new certificates representing those shares to be delivered to Buyer and those
shares that will remain Escrow Shares.  The Representative has the right, but
not the obligation, to direct the Escrow Agent in writing as to whether in
satisfying any Indemnifiable Losses from the Escrow Fund, the Escrow Agent
should release cash or other properties or




                                      3
<PAGE>   59
Escrow Shares, and in what amounts.  Unless the Representative has otherwise
directed the Escrow Agent in writing, in satisfying any Indemnifiable Losses
from the Escrow Fund, the Escrow Agent shall release any cash or other
properties then held in the Escrow Fund prior to releasing any Escrow Shares.
If prior to the applicable Election Date of any release from the Escrow Fund,
the Escrow Agent has received any such contrary instructions on the combination
of cash (or other properties) and Escrow Shares to be released to satisfy
indemnifiable Losses, the Escrow Agent shall follow such instructions.

         If the Representative shall, in accordance with the provisions of
Section 4(b)(i) hereof, protest or otherwise dispute, challenge or disagree
with any assertion contained in any certificate delivered pursuant to Section
4(a) hereof, then such matter shall be determined by arbitration pursuant to
the provisions of Section 9.12(c) of the Stock Purchase Agreement and in such
an event, the Escrow Agent shall not draw upon the Escrow Fund in connection
with such matter until the Operative Event specified in Section 4(b)(ii) or
(iii), as applicable, has been satisfied.

         5.      Distribution After March __, 2000.  On March __, 2000, [second
anniversary of Closing] the Escrow Agent shall deliver to the Representative
(on behalf of the Sellers) the remaining Escrow Shares and other property held
in the Escrow Fund; provided, however, that if at any time prior to such
deliver the Escrow Agent shall have received a certificate as provided in
Section 4(a), and the rights of Buyer shall not have been finally determined as
elsewhere provided in this Agreement, the Escrow Agent shall retain the portion
(but only that portion) of the Escrow Fund still in dispute, until such rights
are finally determined, and then distribute such remaining Escrow Fund in
accordance with the terms and conditions of this Agreement.

         6.      Retention of Escrow Fund.

                 (a)      More than one notice may be given pursuant to Section
         4(a) and in the event one such claim is resolved while other claims
         are pending, the Escrow Agent is authorized to make partial
         distributions from the Escrow Fund to Buyer in accordance with Section
         4 for such resolved claim.

                 (b)      The Escrow Fund, to the extent not distributed due to
         unresolved disputed amounts, shall be held in escrow pursuant hereto
         until final payment or determination in respect of any certificate or
         notice received by the Escrow Agent.  Following the resolution of all
         such pending matters the escrow created hereunder shall terminate and
         the balance of the Escrow Fund shall be delivered to the
         Representative.

         7.      Remedies.  Neither the existence of any right or remedy under
this Agreement or otherwise, nor the exercise or partial exercise of any
thereof, shall constitute a waiver of any other such right or remedy, nor shall
any delay on the part of any party in exercising any right or remedy hereunder,
be deemed to constitute a waiver thereof, and any such right or remedy may be
exercised repeatedly and from time to time.




                                      4
<PAGE>   60
         8.      Tax Matters.  Buyer and Sellers shall provide Escrow Agent
with its taxpayer identification number documented by an appropriate Form W-8
or Form W-9 upon execution of this Escrow Agreement.  Failure so to provide
such forms may prevent or delay disbursements from the Escrow Fund and may also
result in the assessment of a penalty and Escrow Agent's being required to
withhold tax on any interest or other income earned on the Escrow Fund.  Any
payments of income shall be subject to applicable withholding regulations then
in force in the United States or any other jurisdiction, as applicable.  The
Other Parties agree, as between themselves, that the Sellers shall be liable
for, and shall indemnify and hold Buyer harmless from and against any
liabilities for, income taxes arising from or attributable to income earned on
the Escrow Fund if the Escrow Fund is released to the Sellers' Representative
(other than as a credit towards the purchase price upon closing of the
transaction contemplated under the Agreement), and that otherwise Buyer shall
be liable for, and shall indemnify and hold the Sellers harmless from and
against any liabilities for, income taxes arising from or attributable to
income earned on the Escrow Fund.

         9.      Scope of Undertaking.  Escrow Agent's duties and
responsibilities in connection with this Escrow Agreement shall be purely
ministerial and shall be limited to those expressly set forth in this Escrow
Agreement.  Escrow Agent is not a principal, participant or beneficiary in any
transaction underlying this Escrow Agreement and shall have no duty to inquire
beyond the terms and provisions hereof.  Escrow Agent shall have no
responsibility or obligation of any kind in connection with this Escrow
Agreement or the Escrow Fund and shall not be required to deliver the Escrow
Fund or any part thereof or take any action with respect to any matters that
might arise in connection therewith, other than to receive, hold, invest,
reinvest and deliver the Escrow Fund as herein provided.  Without limiting the
generality of the foregoing, it is hereby expressly agreed and stipulated by
the parties hereto that Escrow Agent shall not be required to exercise any
discretion hereunder and shall have no investment or management responsibility
and, accordingly, shall have no duty to, or liability for its failure to,
provide investment recommendations or investment advice to the Other Parties or
either of them.  Escrow Agent shall not be liable for any error in judgment,
any act or omission, any mistake of law or fact, or for anything it may do or
refrain from doing in connection herewith, except for, subject to Section 10
herein below, its own willful misconduct or gross negligence.  It is the
intention of the parties hereto that Escrow Agent shall never be required to
use, advance or risk its own funds or otherwise incur financial liability in
the performance of any of its duties or the exercise of any of its rights and
powers hereunder.

         10.     Reliance; Liability.    Escrow Agent may rely on, and shall
not be liable for acting or refraining from acting in accordance with, any
written notice, instruction or request or other paper furnished to it hereunder
or pursuant hereto and believed by it to have been signed or presented by the
proper party or parties.  Escrow Agent shall be responsible for holding,
investing, reinvesting and disbursing the Escrow Fund pursuant to this Escrow
Agreement; provided, however, that in no event shall Escrow Agent be liable for
any lost profits, lost savings or other special, exemplary, consequential or
incidental damages in excess of Escrow Agent's fee hereunder and Escrow Agent
shall be responsible for its compliance with the terms and conditions of this
Agreement, provided, further, that Escrow Agent shall have no liability for any




                                      5
<PAGE>   61
loss arising from any cause beyond its control, including, but not limited to,
the following: (a) acts of God, force majeure, including, without limitation,
war (whether or not declared or existing), revolution, insurrection, riot,
civil commotion, accident, fire, explosion, stoppage of labor, strikes and
other differences with employees; (b) the act, failure or neglect of any Other
Party or any agent or correspondent or any other person selected by Escrow
Agent unless selected with willful misconduct or gross negligence; (c) any
delay, error, omission or default of any mail, courier, telegraph, cable or
wireless agency or operator; or (d) the acts or edicts of any government or
governmental agency or other group or entity exercising governmental powers.
Escrow Agent is not responsible or liable in any manner whatsoever for the
sufficiency, correctness, genuineness or validity of the subject matter of this
Escrow Agreement or any part hereof or for the transaction or transactions
requiring or underlying the execution of this Escrow Agreement, the form or
execution hereof or for the identity or authority of any person executing this
Escrow Agreement or any part hereof or depositing the Escrow Fund.

         11.     Right of Interpleader.    Should any controversy arise
involving the parties hereto or any of them or any other person, firm or entity
with respect to this Escrow Agreement or the Escrow Fund, or should a
substitute escrow agent fail to be designated as provided in Section 16 hereof,
or if Escrow Agent should be in doubt as to what action to take, Escrow Agent
shall have the right, but not the obligation, either to (a) withhold delivery
of the Escrow Fund in dispute until the controversy is resolved, the
conflicting demands are withdrawn or its doubt is resolved, or (b) institute a
petition for interpleader in any court of competent jurisdiction to determine
the rights of the parties hereto. Should a petition for interpleader be
instituted, or should Escrow Agent be threatened with litigation or become
involved in litigation in any manner whatsoever in connection with this Escrow
Agreement or the Escrow Fund, the losing party of the Other Parties hereby
jointly and severally agree to reimburse Escrow Agent for its attorneys' fees
and any and all other expenses, losses, costs and damages incurred by Escrow
Agent in connection with or resulting from such threatened or actual litigation
prior to any disbursement hereunder.

         12.     Indemnification.    Except as is set forth in Section 10, the
Other Parties hereby jointly and severally indemnify Escrow Agent, its
officers, directors, partners, employees and agents (each herein called an
"Indemnified Party") against, and hold each Indemnified Party harmless from,
any and all expenses, including, without limitation, attorneys' fees and court
costs, losses, costs, damages and claims, including, but not limited to, costs
of investigation, and litigation suffered or incurred by any Indemnified Party
in connection with or arising from or out of this Escrow Agreement, except such
acts or omissions as may result from the willful misconduct or gross negligence
of such Indemnified Party.

         13.     Fees and Expenses of Escrow Agent.  Pool shall pay the fees
and expenses of the Escrow Agent in accordance with the Escrow Agent's normal
fee schedule.

         14.     Notices.    Any notice or other communication required or
permitted to be given under this Escrow Agreement by any party hereto to any
other party hereto shall be considered as properly given if in writing and (a)
delivered against receipt therefor, (b) mailed by registered or

otherwise.  The parties hereto agree that the forum for resolution of any
dispute arising under this Escrow Agreement shall be Harris County, Texas, and
each of the Other Parties hereby consents, and submits itself, to the
jurisdiction of any state or federal court sitting in Harris County, Texas.

         17.     Resignation.    Escrow Agent may resign hereunder upon ten
(10) days' prior written notice to the Other Parties.  Upon the effective date
of such resignation, Escrow Agent shall deliver the Escrow Fund to any
substitute escrow agent designated by the Other Parties in writing.  If the
Other Parties fail to designate a substitute escrow agent within ten (10) days
after the giving of such notice, Escrow Agent may institute a petition for
interpleader.  Escrow Agent's sole responsibility after such 10-day notice
period expires shall be to hold the Escrow Fund (without any obligation to
reinvest the same) and to deliver the same to a designated substitute escrow
agent, if any, or in accordance with the directions of a final order or
judgment of a court of competent jurisdiction, at which time of delivery Escrow
Agent's obligations hereunder shall cease and terminate.

         18.     Assignment.    This Escrow Agreement shall not be assigned by
any party hereto without the prior written consent of the Other Parties hereto
(such consent to assignments being hereinafter referred to collectively as
"Permitted Assigns").

         19.     Severability.    If one or more of the provisions hereof shall
for any reason be held to be invalid, illegal or unenforceable in any respect
under applicable law, such invalidity, illegality or unenforceability shall not
affect any other provisions hereof, and this Escrow Agreement shall be
construed as if such invalid, illegal or unenforceable provision had never been
contained herein, and the remaining provisions hereof shall be given full force
and effect.

         20.     Termination.  This Escrow Agreement shall terminate upon the
transfer, in accordance with Sections 4, 5, or 16 hereof, of the Escrow Fund
provided, however, that the last



                                       8

two sentences of Section 10 hereof and the provisions of Section 11 hereof
shall, in any event, survive the termination hereof.

         21.     General.    The section headings contained in this Escrow
Agreement are for reference purposes only and shall not affect in any way the
meaning or interpretation of this Escrow Agreement.  This Escrow Agreement and
any affidavit, certificate, instrument, agreement or other document required to
be provided hereunder may be executed in two or more counterparts, each of
which shall be deemed an original, but all of which taken together shall
constitute but one and the same instrument.  Unless the context shall otherwise
require, the singular shall include the plural and vise a versa, and each
pronoun in any gender shall include all other genders.  The terms and
provisions of this Escrow Agreement constitute the entire agreement among the
parties hereto in respect of the subject matter hereof, and neither the Other
Parties nor Escrow Agent has relied on any representations or agreements of the
other, except as specifically set forth in this Escrow Agreement.  This Escrow
Agreement or any provision hereof may be amended, modified, waived or
terminated only by written instrument duly signed by the parties hereto.  This
Escrow Agreement shall inure to the benefit of, and be binding upon, the
parties hereto and their respective heirs, devisees, executors, administrators,
personal representatives, successors, trustees, receivers and Permitted
Assigns.  This Escrow Agreement is for the sole and exclusive benefit of the
Other Parties and the Escrow Agent, and nothing in this Escrow Agreement,
express or implied, is intended to confer or shall be construed as conferring
upon any other person any rights, remedies or any other type or types of
benefits.

         IN WITNESS WHEREOF, the parties hereto have executed this Escrow
Agreement to be effective as of the date first above written.

                                VOTING AGREEMENT


         THIS AGREEMENT is made as of March ___, 1998, by and among Al A.
Gonsoulin and ___________________ (who are collectively referred to herein as
the "Shareholders" and individually as a "Shareholder") and Pool Energy Services
Co., a Texas corporation (the "Company").

         The Shareholders will acquire shares of the Company's Common Stock, no
par value per share ("Common Stock"), pursuant to a Stock Purchase Agreement
among the Shareholders, Sea Mar, Inc., Pool Company, and the Company dated of
even date herewith (the "Purchase Agreement").

         The Company and the Shareholders desire to enter into this Agreement
for the purposes of evidencing the Shareholders' agreement to vote certain of
their shares of Common Stock as directed by the Company's Board of Directors
(the "Board"). The execution and delivery of this Agreement is a condition to
the Company's obligation to issue the Common Stock to the Shareholders pursuant
to the Purchase Agreement.

         NOW, THEREFORE, in consideration of the mutual covenants contained
herein and other good and valuable consideration, the receipt and sufficiency of
which are hereby acknowledged, the parties to this Agreement hereby agree as
follows:

         1.       Voting of Shares. The total shares subject hereto are 769,231.
From and after the Closing (as defined in the Purchase Agreement) and until the
second anniversary of the Closing, each Shareholder shall vote all shares of
Common Stock owned by him (not subject to the Escrow Agreement of even date
herewith executed pursuant to the Purchase Agreement) (the "Shareholder Shares")
and shall take all other reasonably necessary or desirable actions within his or
her control (whether in his or her capacity as a stockholder, director, member
of a board committee or officer of the Company or otherwise, and including
without limitation attendance at meetings by proxy for purposes of obtaining a
quorum and execution of written consents in lieu of meetings), and the Company
shall take all necessary or desirable actions within its control (including
without limitation calling special Board and stockholder meetings), so that the
Shareholder Shares are voted as directed by the Board.

         2.       Irrevocable Proxy; Conflicting Agreements.

                  a.  In order to secure each Shareholder's obligation to vote
         his or her Shareholder Shares in accordance with the provisions of
         paragraph 1, each Shareholder hereby appoints J. T. Jonebloed and E. J.
         Spillard, or either of them, as his true and lawful proxy and
         attorney-in-fact, with full power of substitution, to vote all of his
         Shareholder Shares as


<PAGE>   67



         provided for in paragraph 1. J. T. Jonebloed and E. J. Spillard, or
         either of them, may exercise the irrevocable proxy granted to them
         hereunder at any time any Shareholder fails to comply with the
         provisions of this Agreement. The proxies and powers granted by each
         Shareholder pursuant to this paragraph 2 are coupled with an interest
         and are given to secure the performance of the Shareholder's
         obligations to the Company under this Agreement. Such proxies and
         powers will be irrevocable for the term of this Agreement and will
         survive the death, incompetency and disability of such Shareholder.

                  (b) Each Shareholder represents that he has not granted and is
         not a party to any proxy, voting trust or other agreement which is
         inconsistent with or conflicts with the provisions of this Agreement,
         and no holder of Shareholder Shares shall grant any proxy or become
         party to any voting trust or other agreement which is inconsistent with
         or conflicts with the provisions of this Agreement.

         3.       Legend. Each certificate evidencing Shareholder Shares and
each certificate issued in exchange for or upon the transfer of any Shareholder
Shares shall be stamped or otherwise imprinted with a legend in substantially
the following form:

         "The securities represented by this certificate are subject
         to a Voting Agreement dated as of _________ ___, 1998, among
         the issuer of such securities (the "Company") and certain of
         the Company's stockholders. A copy of such Agreement will be
         furnished without charge by the Company to the holder hereof
         upon written request."

The legend set forth above shall be removed from the certificates evidencing any
Shareholder Shares at the request of the Shareholder at any time after the
earlier to occur of (i) the second anniversary of the Closing, or (ii) their
sale to a third party in compliance with all applicable laws.

         4.       Amendment and Waiver. Except as otherwise provided herein, no
modification, amendment or waiver of any provision of this Agreement shall be
effective against the Company or the Shareholders unless such modification,
amendment or waiver is approved in writing by the Company and the Shareholders
so affected. The failure of any party to enforce any of the provisions of this
Agreement shall in no way be construed as a waiver of such provisions and shall
not affect the right of such party thereafter to enforce each and every
provision of this Agreement in accordance with its terms.

         5.       Severability. Whenever possible, each provision of this
Agreement shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement is held to be invalid,
illegal or unenforceable in any respect under any applicable law or rule in any
jurisdiction, such invalidity, illegality or unenforceability shall not affect
any other provision or any other jurisdiction, but this Agreement shall be
reformed,

                                       -2-

<PAGE>   68



construed and enforced in such jurisdiction as if such invalid, illegal or
unenforceable provision had never been contained herein.

         6.       Entire Agreement. Except as otherwise expressly set forth
herein, this document embodies the complete agreement and understanding among
the parties hereto with respect to the subject matter hereof and supersedes and
preempts any prior understandings, agreements or representations by or among the
parties, written or oral, which may have related to the subject matter hereof in
any way.

         7.       Successors and Assigns. Except as otherwise provided herein,
this Agreement shall bind and inure to the benefit of and be enforceable by the
Company and its successors and assigns and the Shareholders and any subsequent
holders of Shareholder Shares and the respective successors and assigns of each
of them, so long as they hold Shareholder Shares. Notwithstanding the foregoing,
however, (i) this Agreement does not apply to any shares placed in the Escrow
Fund pursuant to the Purchase Agreement and (ii) in the event of any sale of the
Shareholder Shares subject to this Agreement, to a third party, all
restrictions, limitation and conditions of this Agreement or to the Shareholders
Shares sold shall be released, null and void.

         8.       Counterparts.  This Agreement may be executed in separate 
counterparts, each of which shall be an original and all of which taken together
shall constitute one and the same agreement.

         9.       Remedies. The parties shall be entitled to enforce their
rights under this Agreement specifically to recover damages by reason of any
breach of any provision of this Agreement and to exercise all other rights
existing in their favor. The parties hereto agree and acknowledge that money
damages may not be an adequate remedy for any breach of the provisions of this
Agreement and that the parties may apply to the arbitrators described in
paragraph ___ below for specific performance and/or injunctive relief (without
posting a bond or other security) in order to enforce or prevent any violation
of the provisions of this Agreement.

         10.       Notices. Any notice provided for in this Agreement shall be
in writing and shall be personally delivered, or mailed first class mail
(postage prepaid) or sent by reputable overnight courier service (charges
prepaid) to the Company and the Shareholders at the addresses set forth below
and to any subsequent holder of Shareholder Shares subject to this Agreement at
such address as indicated by the Company's records, or at such address or to the
attention of such other person as the recipient party has specified by prior
written notice to the sending party. Notices will be deemed to have been given
hereunder when delivered personally, three days after deposit in the U.S. mail
and one day after deposit with a reputable overnight courier service, as
follows;

         THIS EMPLOYMENT AGREEMENT (this "Agreement"), is entered into
effective as of March ____, 1998, by and between Pool Company, a Texas
corporation (the "Company"), and AL A. GONSOULIN (the "Executive").

         The Company desires to employ the Executive and the Executive desires
to accept employment with the Company, on the terms and conditions of this
Agreement.

         Accordingly, the parties agree as follows:

         1.0     Employment Duties and Acceptance.

                 1.1      Employment by the Company; Duties.  The Company

hereof, the "Termination Date"), unless earlier terminated as provided in
Section 4 or unless extended as provided herein (the "Term").  Upon the written
agreement of the Executive and the Company, in each of their sole discretion,
the Term may be extended commencing on the Termination Date and likewise may be

During the Term, the Executive shall be an employee of a limited partnership
which the Company is the general partner of and shall serve in the capacity of
Vice President and General Manager of SEA MAR, INC. ("Sea Mar").  The Executive

Directors of its ultimate parent (collectively, the "Board").  The duties of
the Executive shall include, without limitation, (i) the executive management
of Sea Mar, which shall be operated as a separate business unit; (ii) all
decisions on behalf of Sea Mar relative to Capital Expenditures, dry- docking
expenditures, selection of senior managers, management and key employee
compensation and bonuses for Sea Mar, contract negotiation and Sea Mar profit
and loss responsibility (all of which shall be in accordance with Sea Mar's
prior practices); and (iii) the Executive recruiting, hiring on behalf of Sea
Mar (with the prior approval of the Board) and training a competent,
experienced manager to succeed the Executive at the end of the Term.  All of
the Executive's above-described
<PAGE>   73
responsibilities shall be performed in accordance with the general policies and
practices of the Company and shall be subject to the decisions of the Board.
Provided, however, that if any decisions of the Board directly and adversely
affect the rights of the Sellers under Section 2.4 of the Stock Purchase
Agreement dated as of February __, 1998 (the "Stock Purchase Agreement"),
appropriate adjustments shall be made in the amounts due under Section 2.4.
Any dispute as to the whether any of the Board's decisions adversely affects
such rights of the Sellers or as to the amount of any such adjustment shall be
resolved in accordance with Section 9.12 of the Stock Purchase Agreement.  The
Executive shall not engage in any other business activities except for passive
investments in corporations or partnerships not engaged in the Company Business
(as hereinafter defined).

                 1.2      Acceptance of Employment by the Executive.  The
Executive hereby accepts such employment and shall render the services and
perform the duties described above.

         2.0     Compensation and Other Benefits.

                 2.1      Annual Salary and Supplemental Compensation.  The
Company shall pay during the initial term hereof to the Executive an annual
salary at a rate of $150,000 per year (the "Annual Salary"), subject to
increase at the sole discretion of the Board.  The Annual Salary shall be
payable in accordance with the payroll policies of the Company as from time to
time in effect, but in no event less frequently than once each month, less such
deductions as shall be required to be withheld by applicable law and
regulations.  The Executive shall also receive supplemental compensation in the
amount of $150,000 annually (the "Supplemental Compensation") to be paid
annually on the date which is the sixth month anniversary of the signing of
this Agreement of each year during the Term.

                 2.2      Participation in Employee Benefit Plans.  The Company
agrees to permit the Executive during the Term, if and to the extent eligible,
to participate in any group life, hospitalization or disability insurance plan,
health program, pension plan, vacation or similar benefit plans or other
so-called "fringe benefits" provided by the Company (collectively, "Benefits")
which may be available to other senior executives of the Company on terms no
less favorable to the Executive than the terms offered to such other
executives.  The Company agrees to use its reasonable efforts to obtain
coverage for the Executive upon the commencement of the Term under any such
existing or newly adopted medical expense and hospitalization plan for
employees without premium surcharge and without exclusions for disclosed
preexisting conditions.  The Executive shall cooperate with the Company in

                          3.2.1   Specific Performance.  The right and remedy

<PAGE>   78
thereby be affected and shall be given full effect without regard to the
invalid portions.

                 3.4      Court Review.  If any court determines that any of
the Restrictive Covenants, or any part thereof, is unenforceable because of the
duration or geographical scope of, or scope of activities restrained by, such
provision, such court shall have the power to reduce the duration or scope of
such provision, as the case may be, and in its reduced form, such provision
shall then be enforceable.

                 3.5      Enforceability in Jurisdictions.  The Company and the
Executive intend to and hereby confer jurisdiction to enforce the Restrictive
Covenants upon the courts of any jurisdiction within the geographical scope of

relief provided above in the courts or any other jurisdiction within the
geographical scope of such Restrictive Covenants, as to breaches of such

Covenants as they relate to each jurisdiction being, or this purpose, severable
into diverse and independent covenants.

Executive shall be given 30 days' prior notice from the Board specifically
identifying the reasons which are alleged to constitute Cause or any
termination hereunder and an opportunity to be heard by the Board in the event
the Executive disputes such allegations.  During such 30 day period, the
Company may relieve the Executive of his duties; provided, however, that the
Company shall remain obligated to pay the Executive his compensation during
such 30 day period.

                 4.3      Termination Without Cause.  The Company has the
right, at any time during the Term, subject to all of the provisions hereof,

or which would have been afforded Executive during the remaining Term.  Any
amounts due to the Executive pursuant to this Section 4.3 shall be due and

Term of this Agreement and thereafter had the Executive not been so terminated.

                 4.4      Termination by the Executive.  Any termination of

<PAGE>   80
Executive shall be entitled to receive, and the Company shall be obligated to
pay, the Executive all Salary, Supplemental Compensation and Benefits which
would have been received by the Executive had the termination been without
cause pursuant to Section 4.3 hereof.  The following reasons shall be deemed

whom the Executive reports that is inconsistent with any matter or matters
proposed by the Executive shall not be deemed in any way to constitute a
material change in the Executive's duties.

                 (3)      A reduction in the Annual Salary or Supplemental
Compensation as described in Section 2.1 above.

                 (4)      The failure of the Company substantially to maintain
and to continue the Executive's relative level of participation in the Benefits
except as to general changes in the Benefits applicable to all senior executive
of the Company.

                 (5)      The Company's requiring the Executive to be based
anywhere other than in or within fifty (50) miles of the Sea Mar offices in
Houston, Texas.

or (5) above, the Company fails, within a period of fifteen (15) days after the
receipt of written notice from the Executive setting out the basis for such
termination, to remedy the situation complained of.

                 (b)      Voluntary Termination by the Executive.  In the event
of any voluntary termination of this Agreement by the Executive, other than as
stated above, in Section 4.4(a), during the term hereof, such voluntary
termination shall be deemed to be a breach of the terms of this Agreement.  In
the event of such voluntary termination, the Executive shall be entitled only
to receive payment of all Annual Salary, Supplemental Compensation,





                                       9
<PAGE>   81
and Benefits earned and payable as of the date of such voluntary termination.

         4.5      Termination upon Disability.  If during the Term the
Executive becomes physically or mentally disabled, whether totally or
partially, as evidenced by the written statement of a competent physician
licensed to practice medicine in the United States who is mutually acceptable
to the Company and the Executive or his closest relative if he is not then able
to make such a choice, so that the Executive is unable substantially to perform
his services hereunder for (i) a period of two consecutive months, or (ii) for
shorter periods aggregating three months during any twelve-month period, the
Company may at any time after the last day of the two consecutive months of
disability or the day on which the shorter periods of disability equal an
aggregate of three months, by written notice to the Executive, terminate the
Executive's employment hereunder and discontinue payments of the Annual Salary,
Supplemental Compensation and Benefits accruing from and after the date of such
termination.  The Executive shall be entitled to the full compensation payable
to him hereunder for periods of disability shorter than the periods specified
in clauses (i) and (ii) of the previous sentence.

certain conditions described in Section 2.4 are satisfied.  The parties to this
Agreement acknowledge and agree that all additional consideration described in
Section 2.4 of the Stock Purchase Agreement shall be considered earned and
payable, less amounts previously paid or, if such termination takes place after

                 [LETTERHEAD OF NESSER, KING & LEBLANC, L.L.A.]





                            _________________, 1998




Pool Company
ENSERCH Tower
10375 Richmond Avenue
Houston, Texas 77042

Gentlemen:

         We have acted as special counsel to Sea Mar, Inc., a Louisiana
corporation (the "Company") and the persons (the "Sellers") named in Schedule
3.1(b) to the Stock Purchase Agreement by and among Pool Company, a Texas
corporation (the "Buyer"), Pool Energy Services, Co., a Texas corporation
("Pool"), the Company, and the Sellers dated as of February 10, 1998 (the
"Agreement").  This opinion is being delivered at the request of the Company
and the Sellers pursuant to Section 5.2(g) of the Agreement.  We advise you
that while we represent the Company and the Sellers in connection with a number
of matters, there are many matters about which we have not been consulted and
concerning which we have no knowledge.  Capitalized terms defined in the
Agreement and used but not otherwise defined herein are used herein as so
defined.  For purposes of this opinion, we have examined the Agreement, the
Promissory Note, the Escrow Agreement, and the Voting Agreement (the
"Transaction Documents").

         In connection with rendering the opinions set forth herein, we have
examined originals or copies of such corporate records of the Company, public
records, agreements and other instruments of the Company, certificates of
public officials, certificates of officers and representatives of the Company
and such other documents as we have deemed relevant in connection with
rendering the opinions set forth herein.  As a basis for the opinions
hereinafter expressed and as to various questions of fact material to such
opinions, we have relied upon certificates of officers of the Company, upon
certificates or other assurances from public officials and upon the
representations and warranties of the Company and the Sellers
<PAGE>   86

Page 2

contained in the Agreement, without investigating or verifying their accuracy.

         On the basis of and in reliance upon the foregoing, and subject to the
exceptions, qualifications and limitations contained herein, and in the Stock
Purchase Agreement, including the Schedules and attachments thereto, we are of
the opinion that:

1.       The Company and each Subsidiary is a corporation duly incorporated,
         validly existing and in good standing under the laws of the state of
         its incorporation.  The Company and each Subsidiary has all necessary
         corporate power and authority to own and lease the assets it currently
         owns and leases and to carry on its business as such business is
         currently conducted.

2.       The Company and each Subsidiary is duly authorized, qualified or
         licensed to do business as a foreign corporation and is in good
         standing in each jurisdiction in which their respective right, title
         or interest in or to any of their respective assets, or the conduct of
         their respective business, requires such authorization, qualification
         or licensing, except where the failure to so qualify or to be in good
         standing in such other jurisdiction would not have a material adverse
         effect on any of the assets, the business or the results of operations
         of the Company or of such Subsidiary.

3.       The Company and the Sellers have all necessary power and authority to
         execute, deliver and carry out the terms and provisions of each of the
         Transaction Documents to which they are a party.

4.       The Company and the Sellers have taken or caused to be taken all
         necessary action to authorize the execution, delivery and performance
         of each of the Transaction Documents to which they are a party.  The
         Company and the Sellers have duly executed and delivered the
         respective Transaction Documents to which they are a party, and such
         Transaction Documents constitute the legal, valid and binding
         obligations of the Company and the Sellers, enforceable against them
         in accordance with their terms.

5.       The execution and delivery by the Company and the Sellers of the
         respective Transaction Documents to which they are a party, and the
         performance by them of the agreements contained therein, will not (i)
         violate the Company's Certificate of Incorporation or Bylaws, (ii)
         violate applicable provisions of statutory law or regulation
         applicable to the Company and the Sellers, (iii) result in any
         violation or breach of, or
<PAGE>   87
________________, 1998
Page 3

         constitute a default under, any of its obligations  under any note,
         bond, mortgage, loan agreement, inventory, lease, contract, or any
         other agreement to which any of them is a party or by which any of
         them is bound or to which any of their respective assets are subject,
         except as to consents required in connection with the sale of the
         Company Common Stock contemplated by the Agreement, all of which
         consents have been obtained or requested, (iv) violate any order,
         writ, injunction or decree of any public body applicable to any of
         them.

6.       To our knowledge, except for such filings as are described in the
         Transaction Documents or as have already been made, no consent,
         approval, waiver, order, authorization of, or registration,
         declaration of filing with, any Governmental Entity is required to be
         obtained or made in connection with the delivery of the Transaction
         Documents by the Company and the Sellers or the consummation by the
         Company and the Sellers of the transactions contemplated thereby
         except where the failure to make any such filing or obtain such
         consent, authorization or approval would not have a material adverse
         effect on the Company, its assets or on its business.

7.       The Company's authorized capital consists of (i)100 shares of Class A
         Common Stock, no par value, of which 100 shares are issued and
         outstanding, (ii) 60 shares of Class B Common Stock, no par value of
         which 0 shares are issued and outstanding and (iii) 100 shares of
         Class C Common Stock, no par value, of which 0 shares are issued and
         outstanding.  The record and beneficial ownership of the Company's
         shares is as set forth on Schedule 3.1(b) to the Agreement.  All of
         the issued and outstanding shares of the Company have been duly
         authorized and validly issued, are fully paid and nonassessable, have
         not been issued in violation of any preemptive or similar rights.  The
         Stock constitutes all shares of the outstanding capital stock of the
         Company.  The Company owns 100% of the stock and equity interest of
         each Subsidiary.  Except as set forth on Schedule 3.1(b) to the
         Agreement, there are outstanding (i) no shares of capital stock or
         other voting securities of the Company or any subsidiary, (ii) no
         securities of the Company or any subsidiary convertible into or
         exchangeable for shares of the capital stock or other voting
         securities of the Company, or such Subsidiary, (iii) no options or
         other rights to acquire from the Company or any Subsidiary, and no
         obligation of the Company or any Subsidiary to issue or sell, any
         shares of their capital stock or other voting securities or any
         securities of the Company or any Subsidiary convertible into
<PAGE>   88
________________, 1998
Page 4

         or exchangeable for such capital stock or voting securities, (iv) no
         equity equivalents, interest in the ownership or earnings, or other
         similar rights of or with respect to the Company or any Subsidiary,
         and (v) no shares of any other entity owned by the Company or any
         Subsidiary.  There are no outstanding obligations of the Company or
         any Subsidiary to repurchase, redeem or otherwise acquire any shares,
         securities, options, equity equivalents, interests or rights.  Each
         Seller is the record and beneficial owner of, and upon consummation of
         the transactions contemplated by the Agreement, the Buyer will
         acquire, good, valid and marketable title to, the number of shares of
         Stock set forth opposite the name of such Seller on Schedule 3.1(b) to
         the Agreement, free and clear of all Encumbrances, other than (i)
         those that may arise by virtue of any actions taken by or on behalf of
         the Buyer or its affiliates or (ii) restrictions on transfer that may
         be imposed by federal or state securities laws.

8.       To the best of our knowledge, after due inquiry, there is no
         litigation, proceeding, claim or governmental investigation pending
         or, threatened seeking relief or damages which, if granted, would
         materially adversely affect the Company, any Subsidiary, any of their
         respective assets, or the ability of the Buyer to use and operate the
         assets of the Company and the Subsidiaries or which would prevent the
         consummation of the transactions contemplated by this Agreement and
         (ii) neither the Sellers, the Company nor any Subsidiary has been
         charged with any violation of or threatened with a charge or violation
         of, nor are there any facts or circumstances that, if discovered by
         third parties, could give rise to a charge or a violation of, any
         provision of Applicable Law or regulation which charge or violation,
         if determined adversely to either the Sellers, the Company or any
         Subsidiary, would materially adversely affect the Business or the
         results of operations of the Company or its Subsidiaries or that might
         reasonably be expected to materially affect the right of the Buyer to
         own the Stock or operate the Company's and Subsidiaries' Business
         after the Closing Date in substantially the manner in which it is
         currently operated.

9.       Except as described in Schedule 3.1(c) to the Agreement, the
         execution, delivery and performance of the Agreement by the Sellers
         and the Company and the consummation by them of the transactions
         contemplated by the Agreement (i) will not violate (with or without
         the giving of notice or the lapse of time or both) or require any
         consent, approval, filing or notice under, any provision of any
         Applicable Law and (ii) will not result in the creation of any
         Encumbrance on the
<PAGE>   89
________________, 1998
Page 5

         Stock under, conflict with, or result in the breach or termination of
         any provision of, or constitute a default under, or result in the
         acceleration of the performance of the obligations of the Sellers, the
         Company or any Subsidiary under, or result in the creation of an
         Encumbrance upon any portion of the assets of the Company or any
         Subsidiary pursuant to, the documents of incorporation or by-laws of
         the Company or any Subsidiary.  The Stock is transferable and
         assignable to the Buyer as contemplated by the Agreement without the
         waiver of any right of first refusal or the consent of any other party
         being obtained, and there exists no preferential right of purchase in
         favor of any person with respect of any of the Stock or the Business
         or any of the assets of the Company.

10.      Except as set out in Schedule 3.1(w) to the Agreement, to the best of
         our knowledge, each of the Vessels is owned by the Company free and
         clear of all liens, charges and rights of others and is duly
         documented under the laws and flag of the U.S. entitling the Vessels
         to operate in the U.S. coastwise trade and on a worldwide basis in
         support of the offshore petroleum industry.

         The opinions expressed herein are subject to the following
assumptions, exceptions, limitations and qualifications:

1.       We have assumed the legal capacity of natural persons, the genuineness
         of signatures, the authenticity of all documents submitted to us as
         originals, the conformity to original documents of all documents
         submitted to us as copies and the authenticity of the originals of
         such copied documents.

2.       We have also assumed (i) that the Buyer and Pool have the power,
         authority and legal right and capacity to enter into and perform the
         Transaction Documents and the other agreements contemplated by the
         Transaction Documents that are required on their part to be performed,
         and that Pool and Company are Texas corporations, (ii) the due
         authorization, execution and delivery by the Buyer and Pool of the
         Transaction Documents to which they are parties, (iii) that the
         Transaction Documents are the valid and binding obligations of, and
         enforceable against the Buyer and Pool, (iv) neither the Buyer nor
         Pool is involved in any court, administrative or other proceeding or
         subject to any order, writ, injunction or decree which would prohibit
         the execution, delivery or performance of the Transaction Documents by
         such parties, and (v) that there is
<PAGE>   90
________________, 1998
Page 6

         no requirement of consent, approval or authorization by any person or
         governmental authority with respect to the Buyer or Pool other than as
         has been duly obtained.

3.       To the extent any of the opinions expressed herein relate to the
         existence or absence of facts and/or involve materiality or legal
         conclusions based upon the existence or absence of facts and/or
         materiality, we have relied solely upon the judgment of one or more
         officers of the Company with respect to all factual issues necessary
         to determine the existence or absence of facts and what is material or
         what would constitute a material adverse effect under the
         circumstances.

4.       The enforceability of any Transaction Document to which the Company or
         the Sellers is a party may be limited by (i) bankruptcy, insolvency,
         moratorium and similar laws from time to time in effect and affecting
         creditors' rights or the collection of obligations generally,
         including, without limitation, laws generally defining and restricting
         fraudulent conveyances, (ii) principles of equity, and (iii)
         requirements of commercial reasonableness, good faith, and fair
         dealing.  Rights to indemnification or contribution under the

              [LETTERHEAD OF GARDERE WYNNE SEWELL & RIGGS, L.L.P.]





                             _______________, 1998


Parties listed on Schedule A attached hereto.

Gentlemen:

         We have acted as counsel to Pool Company, a Texas corporation
("Buyer") and Pool Energy Services, Co., a Texas corporation ("Pool")  in
connection with the Stock Purchase Agreement by and among the Buyer, Pool, Sea
Mar, Inc., a Louisiana corporation (the "Company"), and the Sellers dated as of
January ___, 1998 (the "Agreement").  This opinion is being delivered at the
request of the Buyer and Pool pursuant to Section 5.3(d) of the Agreement.  We
advise you that while we represent the Buyer and Pool in connection with a
number of matters, there are many matters about which we have not been
consulted and concerning which we have no knowledge.  Capitalized terms defined
in the Agreement and used but not otherwise defined herein are used herein as
so defined.  For purposes of this opinion, we have examined the Agreement, the
Registration Agreement, the Voting Agreement and the Escrow Agreement (the
"Transaction Documents").

         In connection with rendering the opinions set forth herein, we have
examined originals or copies of such corporate records of the Buyer and Pool,
certificates of public records, agreements and other instruments of the Buyer
and Pool, certificates of public officials, certificates of officers and
representatives of the Buyer and Pool and such other documents as we have
deemed relevant in connection with rendering the opinions set forth herein.  As
a basis for the opinions hereinafter expressed and as to various questions of
fact material to such opinions, we have relied upon certificates of officers of
the Buyer and Pool, upon certificates or other assurances from public officials
and upon the representations and warranties of the Buyer and Pool contained in
the Agreement, without investigating or verifying their accuracy.

         On the basis of and in reliance upon the foregoing, and subject to the
exceptions, qualifications and limitations contained herein, we are of the
opinion that:

1.       Each of the Buyer and Pool is a corporation validly existing and in
         good standing under the laws of the State of Texas.

2.       Each of the Buyer and Pool have the requisite corporate power and
         authority to execute, deliver and carry out the terms and provisions
         of each of the Transaction Documents to which it is a party.

3.       Each of the Buyer and Pool have taken or caused to be taken all
         necessary corporate action to authorize the execution, delivery and
         performance of each of the Transaction Documents to which it is a
         party.  The Transaction Documents constitute the legal, valid and
         binding obligations of the Buyer and Pool, enforceable against them in
         accordance with their terms.

4.       The execution and delivery by each of the Buyer and Pool of the
         Transaction Documents to which it is a party, and the performance by
         each of them of the agreements contained therein, will not (i) violate
         their respective Articles of Incorporation or Bylaws, or (ii) violate
         applicable provisions of statutory law or regulation applicable to
         each of them.

5.       To our knowledge, except for such filings as are described in the
         Transaction Documents or as have already been made, no consent,
         approval, waiver, order, authorization of, or registration,
         declaration of filing with, any Governmental Entity is required to be
         obtained or made in connection with the delivery of the Transaction
         Documents by the Buyer and Pool or the consummation by the Buyer and
         Pool of the transactions contemplated thereby, except where the
         failure to make any such filing or obtain such consent, authorization
         or approval would not have a material adverse effect on the Buyer or
         Pool.

6.       The shares of Pool Stock, when issued in accordance with the terms of
         this Agreement, will be validly issued, fully paid and non-assessable.

         The opinions expressed herein are subject to the following
assumptions, exceptions, limitations and qualifications:

1.       We have assumed the legal capacity of natural persons, the genuineness
         of signatures, the authenticity of all documents submitted to us as
         originals, the conformity to original documents of all documents
         submitted to us as copies and the authenticity of the originals of
         such copied documents.

2.       We have also assumed (i) that the Company and the Sellers have the
         power, authority and legal right and capacity to enter into and
         perform the Transaction Documents and the other agreements
         contemplated by the Transaction Documents that are required on their
         part to be performed, (ii) the due authorization, execution and
         delivery by the Company and the Sellers of the Transaction Documents,
         (iii) that the Transaction Documents are the valid and binding
         obligations of, and enforceable against the Company and the Sellers,
         (v) the Company and the Sellers are not involved in any court,
         administrative or other proceeding or subject to any order, writ,
         injunction or decree which would prohibit the execution, delivery or
         performance of the Transaction Documents by such parties, and (vii)
         that there is no requirement of consent, approval or authorization by
         any person or governmental authority with respect to the Company and
         the Sellers other than as has been duly obtained.

3.       To the extent any of the opinions expressed herein relate to or
         involve materiality, we have relied solely upon the judgment of one or
         more officers of the Buyer and Pool with respect to all factual issues
         necessary to determine what is material or what would constitute a
         material adverse effect under the circumstances.

4.       The enforceability of the Transaction Documents to which each of the
         Buyer and Pool is a party may be limited by (i) bankruptcy,
         insolvency, moratorium and similar laws from time to time in effect
         and affecting creditors' rights or the collection of obligations
         generally, including, without limitation, laws generally defining and
         restricting fraudulent conveyances, (ii) principles of equity, and
         (iii) requirements of commercial reasonableness, good faith, and fair
         dealing.  Rights to indemnification or contribution under the
         Transaction Documents may be limited by federal or state securities
         laws and policies related thereto.

         CONSTRUCTION CONTRACT ASSIGNMENT dated as of March ___, 1998 between
Sea Mar Equipment, Inc. a Louisiana corporation (herein referred to as the

         WHEREAS, the Assignor has entered into a Vessel Construction Contract

entitled to exercise an option to have the Builder construct eight additional
vessels with specified price parameters; and

         WHEREAS by letter dated October 14, 1997, duly acknowledged by the
Builder, the Assignor exercised its option for eight additional vessels to be
constructed under the Construction Contract (the original two offshore supply
vessels and the eight option offshore supply vessels herein referred to as the
"Vessels"); and

         WHEREAS under the terms of the Construction Contract, Al Gonsoulin
personally guaranteed performance of the Assignor's obligations under the
Construction Contract and executed a written guaranty agreement dated August 1,

1.       The Assignor does hereby sell, assign, absolutely and not by way of
         security, transfer and set over unto the Assignee all right, title and
         interest of the Assignor in and to the Construction Contract
         including, without limitation, (a) the right upon valid tender by the
         Builder to purchase each of the Vessels pursuant to the Construction
         Contract, and the right to take title to the Vessels pursuant to the
         Construction Contract, (b) all claims for damages arising as a result
         of any failure by the Builder to perform or observe any of the terms
         of the Construction Contract, and all rights, benefits and claims
         under all warranty and indemnity provisions contained therein, and (c)
         any and all rights of the Assignor to compel performance of the
         Construction Contract, to the same extent as if the Assignee were the
         "Purchaser" named in the Construction Contract.  The Assignee hereby
         accepts such assignment.

2.       The Assignor does hereby constitute the Assignee, its successors and
         assigns, the Assignor's true and lawful attorney, irrevocably, with
         full power (in the name of the Assignor or otherwise) to ask, require,
         demand, receive, compound and give acquittance for any and all monies
         and claims for monies due and to become due under or arising out of
         the Construction Contract to the extent that the same have been
         assigned by this Agreement and, for such period as the Assignee may
         exercise rights with respect thereto under this Agreement, to endorse
         any checks or other instruments or orders in connection therewith and
         to file any claims or take any action or institute (or if previously
         commenced, assume control of) any proceedings and to obtain any
         recovery in connection therewith which the Assignee may deem to be
         necessary or advisable in the premises.

3.       The Assignor hereby represents, warrants and covenants that (a) the
         Construction Contract is in full force and effect and is valid and
         enforceable against the Assignor in accordance with its terms; (b)

         right, title or interest in or to the Construction Contract to anyone
         other than the Assignee; (d) all right, title and interest in and to
         the Construction Contract to be assigned hereby has been duly and
         validly assigned to the Assignee hereunder; and (e) all governmental
         consents and approvals necessary for the execution, delivery by the
         Assignor of, and the performance by it of its obligations under, this

         further action as the Assignee may reasonably request in order to
         obtain the full benefits of this Assignment and of the rights and
         powers herein granted.  In
<PAGE>   98
         addition, if any claim or remedy purported to be conveyed or assigned
         to the Assignee hereunder shall not be valid or enforceable by the
         Assignee, the Assignor will pursue such claim or remedy in its own
         name, at its own expense, to the extent requested by and for the
         benefit of the Assignee.

5.       Each right, power and authority granted or given to the Assignee
         hereunder may be exercised by the Assignee or by such employees,
         agents or attorneys-in-fact as it may designate.

6.       This Assignment shall be governed by and construed in accordance with
         the internal laws of the State of Louisiana.

                        VESSEL CONSTRUCTION CONTRACT

         THIS VESSEL CONSTRUCTION CONTRACT (the "Contract") entered into as of
this 1st day of August, 1997 by and between Halter Marine, Inc., a corporation
organized and existing under and by virtue of the laws of the State of Nevada
(hereinafter called "Builder"), and Sea Mar Equipment, Inc., a corporation
organized and existing under and by virtue of the laws of Louisiana
(hereinafter called "Owner").

                            W I T N E S S E T H:

ARTICLE I - DESCRIPTION OF VESSEL:

         Builder, for and in consideration of the sum to be paid it by Owner as
hereinafter set forth, unless prevented by "Force Majeure" as hereinafter
defined, agrees to design, build, equip, and complete at Builder's Yard as
designated in the attached Exhibits, free and clear from liens, claims and
encumbrances, two (2) 200 ft. Supply Vessels (hereinafter referred to as "The
Vessel", "each Vessel", or "Vessels", collectively, as the case may be), each
of which is described on the attached Exhibits "A-1" and "A-2" and which shall
be constructed in accordance with: (a) this Contract, (b) Specifications dated
July 11, 1997 (Exhibit "B" to this Contract) (the "Specifications"), and (c)
Outboard Profile and Arrangement Drawing No. 1A, dated June 5, 1997 and hand
dated July 11, 1997 (Exhibit "C" to this "Contract") (the "Drawings")
(hereinafter collectively as to each respective Vessel, the "Contract
Documents"), all of which have concurrently been identified by the parties
hereto and made a part hereof as if fully set forth herein.

         Except for any Owner-furnished equipment as may be listed in the
Specifications for a particular Vessel, Builder agrees to furnish all design,
plant, labor, tools, equipment and material necessary for the construction and
delivery of such Vessel(s).

         The Vessel shall be constructed to meet the applicable requirements of
regulatory bodies as set forth in the Contract Documents, and certificates
evidencing the required classifications shall be furnished by Builder to Owner.

         If any enforced changes in the rules and regulations (or
interpretations thereof) of the American Bureau of Shipping or other applicable
classification society or any governmental agency (collectively, "Enforced
Changes") are made subsequent to the date of this Contract necessitating
alterations or additions to the Vessel(s); whereby the cost of any Vessel is
increased and/or the time required for completion for any Vessel is extended,
Owner shall authorize, and pay for, as a change order under this Contract, such
alterations, additional work items, outfit and/or equipment, and shall allow
Builder such additional time as may be





                                       1
<PAGE>   2
required to meet the Enforced Changes, in accordance with Article IV hereof.
Owner will only be responsible for the costs of the Enforced Changes if (i)
Owner is advised of the Enforced Changes, (ii) Owner is given an opportunity to
address the Enforced Changes with the applicable regulatory body before any
work is performed and (iii) any resultant changes in the scope of work are the
subject of prior agreement as to price and schedule impact before the work is
performed; provided, however, any delay by Owner in accepting the Enforced
Changes shall be an event of "Force Majeure" hereunder, and in the event Owner
does not agree to be responsible for the Enforced Changes Builder shall be
relieved of any responsibility to comply with the requirements of the
applicable regulatory body set forth in the Contract Documents necessitated by
that Enforced Change.

         All general language or requirements contained in the
Contract Documents for each Vessel and all other requirements inconsistent or
in conflict with the provisions of this Contract are superseded by this
Contract, it being the intent of the parties that the provisions of this
Contract shall prevail.  If there is any conflict or inconsistency between the
Contract Plans and Specifications, the Specifications shall control.

Article II - PRICE AND PAYMENT:

         Owner, in consideration of the true and faithful performance on the
part of the Builder, agrees to pay to Builder the sum of U.S. $16,550,000.00,
hereinafter called the "Contract Price". The portion of the Contract Price
attributable to each Vessel (hereinafter called the "Assigned Value") is
contained in Exhibit "A-1" and "A-2".

         The Assigned Value for each Vessel shall be payable in two (2)
installments.  The initial payment in an amount equal to ten percent (10%) of
the Assigned Value for each Vessel shall be payable upon execution of this
Contract. The remaining ninety percent (90%) of the Assigned Value of each
Vessel and any amounts due for extras, change orders, other additional costs
as provided in this Contract, together with interest at the Agreed Rate (as
defined below) (such payment is the "Final Payment"), shall be payable upon
delivery of the Vessel.

         Owner and Builder have agreed on the following milestone events (each
a "Milestone Event") for the construction of the Vessel and on the percentage
of the Assigned Value of each Vessel allocable to each Milestone Event:

Delivery of Vessel                                            8%
</TABLE>

         Interest shall accrue on each respective portion of the Assigned Value
of each Vessel at the rate of seven and one-quarter percent (7 1/4%) per annum
(the "Agreed Rate") during the period between the time Builder achieves the
corresponding Milestone Event and Builder's receipt of the Final Payment. All
accrued interest shall be payable at the time of the Final Payment. Interest
shall accrue at the Agreed Rate on that portion of the Assigned Value of each
Vessel attributable to each Milestone Event from the time that Builder achieves
such Milestone Event until Builder's receipt of the Final Payment. For
instance, interest shall accrue at the Agreed Rate on fifteen percent (15%) of
the Assigned Value for each Vessel from the time of Builder's receipt of steel
until Builder's receipt of the Final Payment. In addition, interest shall also
accrue at the Agreed Rate for that portion of the Assigned Value of each Vessel
attributable to the other Milestone Events from the time of each respective
Milestone Event until Builder's receipt of the Final Payment.  The parties
agree and acknowledge that while interest shall not accrue during the Grace
Period (as hereinafter defined), interest shall continue to accrue at the
Agreed Rate during the Liquidated Damages Period (as hereinafter defined).

         In the event the down payment required for each Vessel shall not be
tendered to Builder in immediately available funds by the close of business
within ten (10) business days of Owner's execution of this Contract, either
party shall have the right to terminate this Contract, in which event neither
party shall have any further liability to the other. In the event Builder
chooses not to terminate this Contract, then the Stipulated Date of Delivery as
described in Article III shall be extended one day for every day that any
portion of the deposit is made after the foregoing deadline.

         The Builder shall submit appropriate invoices and/or certificates to
evidence the occurrence of each Milestone Event for





                                       3
<PAGE>   4

each Vessel which shall be reviewed and approved in writing by Owner's
representatives. Payments for all extras, less credits for any deductions,
shall be made in cash upon the completion and prior to delivery of each Vessel.
The full Assigned Value, including all amounts owed for extras, change orders
and all other additional costs as provided in this Contract, must be paid prior
to delivery of each Vessel.

         Should Owner (a) fail to take delivery of the Vessel within ten (10)
days of the completion of the Vessel (except for any Minor Items (as
hereinafter defined)) and Owner's receipt of written notice that the Vessel is
complete and available for Delivery in accordance with the Contract Documents
(except for any Minor Items), or (b) fail to timely pay to Builder any amounts
due hereunder, Owner shall be in default of this Contract and Builder shall
have the right to mitigate its damages and protect its rights and interests.
Without limiting the foregoing, Builder shall be entitled either to terminate
this Contract or to sue Owner for specific performance. If Builder elects to
terminate this Contract, then Builder shall have the option, in its sole
discretion, to (i) sue Owner for damages as a result of its breach hereunder
and apply any deposits or other payments made hereunder toward those damages,
or (ii) retain title to each Vessel and/or sell the Vessel, free of any claim
of Owner, and retain any deposits or other payments made hereunder. Provided,
however, Builder shall refund to Owner the difference, if any, between: (X) the
sum of (i) the sale price of the Vessel resulting from any sale by Builder
pursuant to the terms of this paragraph, and (ii) the aggregate of all payments
to Builder from Owner pursuant to this Contract, minus (Y) the sum of (i) the
Assigned Value of the Vessel (as adjusted pursuant to the terms of this
Contract), and (ii) the aggregate of all reasonable costs and expenses to
Builder directly resulting from the sale contemplated hereunder, including (i)
storage costs, relocation costs, and rescheduling costs and (ii) the default
by Owner or the sale of the Vessel pursuant to the provisions of this
paragraph, including the costs and expenses of the enforcement of Builder's
rights under this paragraph. If the





                                       4
<PAGE>   5
sum of (X) is greater than the sum of (Y), Owner shall be reimbursed such
difference. Other than as expressly set forth herein, in any such event,
Builder shall have no further obligation whatsoever to Owner hereunder.

         The making of any partial payments shall in no way estop Owner from
thereafter asserting any right or remedy accruing to its because of failure of
Builder to deliver the completed Vessel in accordance with the terms hereof.

ARTICLE III - TIME AND CONDITIONS OF DELIVERY:

         Each Vessel, after required trials, completed in accordance with the
Contract Documents, shall be delivered to Owner, on or before the date
indicated on the attached Exhibits "A-1" and "A-2" for the delivery of each
Vessel (hereinafter called the "Stipulated Date of Delivery"), or on such later
date or dates as may be required by reason of agreed changes in the Vessel, or
by reason of specified delays resulting from "Force Majeure", as that term is
defined in Article VI.

         Builder shall deliver each Vessel to Owner at a location set forth on
the attached Exhibit "A-1" and "A-2" (the "Place of Delivery"). All costs and
expenses of transporting each Vessel to the Place of Delivery shall be borne by
and be the obligation of the Builder.  All costs and expenses of operating
and/or transporting each vessel as it has reached the Place of Delivery and
been accepted by Owner shall be borne by and be the obligation of Owner.

         Builder shall furnish Owner on delivery of each Vessel a Bill of Sale
(if necessary) and a Builder's Certification, together with whatever other
documents may be required by law or by any regulatory agency of the United
States having relevant jurisdiction in order for Owner to document the Vessel
in its name. Any expense in connection with the furnishing of such documents
and with the documentation of such Vessel shall be paid by Owner.

         Owner shall execute a Delivery and Acceptance Certificate immediately
prior to the time of delivery and acceptance of the Vessel by Owner,
substantially in the form of Exhibit "D".





                                       5
<PAGE>   6
         If completion and delivery of each Vessel shall be delayed more than
thirty (30) days beyond the respective Stipulated Date of Delivery (such 30 day
period is the "Grace Period"), as adjusted in accordance with the provisions of
Articles IV and VI hereof or because of some other act of the Owner, or it is
agreed that Owner will suffer damages which are difficult of ascertainment and
the parties hereby agree that Owner shall sustain, and Builder agrees to pay
as liquidated damages in accordance with the amounts noted on Exhibits "A-1"
and "A-2" for the Vessel whose delivery is delayed for each calendar day of
delayed delivery from the thirtieth (30th) day after the Stipulated Date of
Delivery (as adjusted) until such time that Builder tenders delivery of the
Vessel to the Owner in accordance with the Contract Documents (such period
during which liquidated damages may accrue is the "Liquidated Damages Period"),
except for minor items which do not adversely affect the commercial utility or
efficient and lawful operation of the vessel (collectively, the "Minor Items")
and Builder has agreed to correct such Minor Items in a timely manner, not to
exceed a total of ninety (90) days or a total sum for liquidated and agreed
damages for the Vessel not to exceed the total amount noted on Exhibits "A-1"
and "A-2". All liquidated damages accruing hereunder shall be payable upon
delivery of each affected Vessel. Except for Owner's termination rights set
forth in the following paragraph, Owner's right to such liquidated damages
shall be Owner's sole and exclusive remedy for damages or loss due to late
delivery of the Vessel and Owner specifically waives all other rights or
remedies at law or in equity therefor.

         Should the Stipulated Date of Delivery be extended pursuant to this
Contract for more than one hundred twenty (120) days from the Stipulated Date
of Delivery (as adjusted pursuant to the terms of this Contract) solely based
on delay by Builder, upon payment to Builder of all costs incurred to date by
Builder in construction of the Vessel that are not included in the first
installment of the Contract Price made to Builder as depicted in the Assigned
Value documented by the parties, as adjusted for agreed change orders less all
liquidated damages and less or without any accrued





                                       6
<PAGE>   7
interest from the Stipulated Date of Delivery until Owner takes possession of
the Vessel, Owner shall have right, at its option, to terminate this Contract by
providing written notice to Builder and to have the Vessel completed by another
shipyard. If so requested by Owner, Builder shall (a) in the least expensive
manner, complete all work required to permit the Vessel to be safely removed
from the Builder's yard, (b) remove its employees, agents and contractors,
together with their equipment, and (c) render all necessary assistance to the
Vessel in leaving the Builder's yard at the earliest moment convenient to
Builder. Once Owner has documented Owner's cost to complete the Vessel, Builder
shall pay to Owner the difference, if any, between (a) the sum of (i) Owner's
reasonable auditable costs of completion and (ii) liquidated damages that have
accrued hereunder with respect to the Vessel, and (b) the Assigned Value for the
Vessel, as adjusted for change orders performed by Builder.

         Notwithstanding anything contained in this Contract to the contrary,
should Owner terminate this Contract pursuant to the preceding paragraph, Owner
shall have one hundred eighty (180) days from such termination to notify Builder
of any defective materials or workmanship which were both (i) included in the
percentage completion of the construction of the Vessel to date by Builder and
(ii) represented in the amount paid to Builder upon such termination.  In no
event shall Builder be liable to Owner for any sum in excess of the cost of
repairs or replacements of the materials or workmanship, nor shall Builder be
obligated to repair or replace any material or workmanship, where such repair or
replacement is caused by Owner, its contractors (except Builder), subcontractors
or employees. Builder shall have no responsibility whatsoever for such defective
materials or workmanship if Owner does not notify Builder within the period set
forth above in this paragraph.

         Owner and Builder waive, remit and release each other from any claims
or causes of action for consequential damages arising out of either party's
failure to perform or timely perform under this Contract. For purposes of this
waiver and release, consequential





                                       7
<PAGE>   8
damages shall be considered any and all claims for delay (other than for
liquidated damages as set forth herein), disruption, loss of profits, extended
project management costs, overhead costs, lost revenues, interest expense, loss
of revenue from other projects, or any other similar consequential damages,
irrespective of the basis of such claimed consequential damages and even if
caused or contributed to by the fault, neglect, or breach of contract of the
other party.

ARTICLE IV - CHANGES IN THE PLANS AND SPECIFICATIONS:

         Subject to the requirements of other work then pending in Builder's
yard, Owner has the right to request any deletions from or additions to the
plans and Specifications for each Vessel on giving due notice in writing to
Builder, the dollar amount of any such changes to be agreed upon in advance by
Owner and Builder, and added to, or deducted from, the total Contract Price and
Assigned Value for such Vessel. If any such change shall delay the completion of
such Vessel, Builder shall be allowed a reasonable extension of time of the
Stipulated Date of Delivery sufficient to cover such delay. A statement of the
increase or decrease to the Contract Price and Assigned Value, and/or any
additional contract time required, as aforesaid, shall be submitted to Owner by
Builder in the form shown on Exhibit "E", and shall be approved by Owner in
writing before any such change is made. Notwithstanding the foregoing, no change
shall be made in the general dimensions and/or characteristics of any Vessel
which would diminish the capacity of the Vessel to perform as originally
intended by the Contract Documents, except by mutual consent of the parties.

         All change orders in excess of $25,000.00 shall be handled in the
following manner. Upon the occurrence of the next Milestone Event, interest will
accrue on change orders as agreed in the written change order executed prior to
performance of the changed work.





                                       8
<PAGE>   9
ARTICLE V - INSPECTION BY OWNER'S REPRESENTATIVE:

         Builder will furnish reasonable space at its yard for the duly
authorized representative(s) of Owner who shall have reasonable access to the
work of Builder. Owner's representative(s) shall promptly inspect and accept all
workmanship and material which is in conformity with the Contract Documents
and shall with equal promptness, reject all workmanship and material which does
not comply with the Contract Documents, provided that the acceptance of such
workmanship and material by Owner's representative shall not prejudice the
rights of Owner under the provisions of Article VII hereof.

         Access to the vessel shall be at Owner's own risk. Builder assumes no
responsibility and Owner assumes full liability for any injury that he or his
representative, agent or contractors may sustain on the vessel during its
construction and hereby fully releases and discharges Builder from any
liability with respect thereto.

ARTICLE VI - FORCE MAJEURE:

         All agreements of the Builder contained in this Contract respecting
the Stipulated Date of Delivery of each Vessel shall be subject to extension by
reason of "Force Majeure", which term is hereby declared to include the
following: strikes, lockouts, or other industrial disturbances; short or late
delivery of material (including particularly steel, tubing, piping, wiring, and
all components); unavailability or interruptions or inadequacy of fuel
supplies; acts of God or of the Owner; war, preparation for war, the
requirement, urgency or intervention of Naval or Military executives or other
agencies of government; arrests and restraints of rulers and people, blockade,
sabotage, vandalism and malicious mischief, threats of vandalism and bomb
scares and insurrection; landslides, floods, hurricanes, earthquakes; collisions
and fires; any delays of carriers by land, sea or air; non-delivery and/or late
delivery of all Owner Furnished Supplies, material or equipment, delays due to
changes authorized by Owner, and delays of material which the Builder by
reasonable precaution cannot avoid. Rain shall not be considered a "Force
Majeure" event unless it





                                       9
<PAGE>   10
occurrence requires a shutdown of a substantial portion of the Builder's yard
prior to 12:00 noon on a regularly scheduled work day. For each day on which
rain requires a shut down as aforesaid, Builder shall be entitled to one (1)
day's extension of the Stipulated Date of Delivery. Delays in receiving
Material, equipment, or fuel or short deliveries thereof (except Owner
Furnished Material) shall be considered a "Force Majeure" event if Builder
shows that such materials or supplies were timely ordered and that such due
diligence was exercised to obtain timely delivery thereof; and no other
alternate source of supply was reasonably available.

         Within ten (10) days of knowledge of any "Force Majeure" event which
may affect the Stipulated Date of Delivery, the Builder shall notify the Owner
in writing and shall furnish an estimate, if possible, of the extent of the
probable delay. Upon receipt of any such notice, the Owner shall, within ten
(10) days, acknowledge the same in writing and indicate agreement that such
development is to be treated as a "Force Majeure" event, or state any
objections, and the reasons therefor, to acceptance of this development as a
"Force Majeure" event. If Builder fails to notify Owner of a "Force Majeure"
event within ten (10) days after knowledge of the event, Builder shall be
estopped from thereafter claiming "Force Majeure" for any period of delay more
than ten (10) days prior to said notice. If Owner should fail to respond
within ten (10) days, the extension of time shall be considered approved.

         If the completion of any Vessel is delayed one or more time by "Force
Majeure", the Stipulated Date of Delivery of that Vessel and all subsequent
Vessels (including all Option Vessels [as hereinafter defined]) shall be
extended by a period equal to the period of such delay or delays; provided,
however, for any "Force Majeure" events arising due to floods, hurricanes, or
earthquakes or other similar Acts of Gods which result in any period of delay
in excess of five (5) days, no interest shall accrue on the portion of the
Assigned Value which ordinarily would be accruing interest during such extended
"Force Majeure" period.

ARTICLE VII - WARRANTY:

         During the Warranty Period, as hereinafter defined, Builder warrants
that all work furnished by Builder hereunder shall have been performed in a
good and workmanlike manner. The provisions set forth herein as to the
liabilities of the Builder are to apply also to all work furnished by
subcontractors in Builder's performance of this Contract.

         Builder shall have no responsibility whatsoever with respect to any
defect, claim, or loss of the Vessel not reported in writing to Builder within
one hundred eighty (180) days from the Delivery Date (as specifically defined
in this Article VII) (such period being hereinafter referred to as the
"Warranty Period").

         The Warranty granted to Owner by Builder shall extend only to those
claims reported in writing to Builder within such Warranty Period. For purposes
solely for this Article VII, "Delivery Date", shall be defined as the earlier
of the following: (1) fourteen (14) days after Owner's failure to accept
delivery of the Vessel which is complete in accordance with the Contract
Documents (except for Minor Items), or (2) the date of actual delivery of the
Vessel. In the event Owner notifies Builder of any claim covered under this
Warranty, Builder will make repairs and/or replacement (including any design
changes) at its option, at one of Builder's yards without expense to Builder
for transporting the Vessel, or any component thereof, to or from that yard;
provided, however, that if it is not practical to have the Vessel proceed to
such yard, Owner may, with prior written consent of Builder, have such repairs
and/or replacement made elsewhere, and, in such event, Builder shall reimburse
Owner a sum equivalent to (i) the amount Builder would have expended, at its
own yard at Builder's then prevailing rates, or (ii) the amount actually
expended by Owner, whichever is less. In no event shall Builder be responsible
for any sum in excess of the cost of the repairs and/or replacement as
specified herein, and Builder shall in no event be responsible for any claims
to property, persons, and/or consequential or punitive damages, including, but

wages, and any other consequential or punitive damages arising out of any breach
of this Contract or faulty or negligent performance thereof.  Owner
specifically releases Builder from any claims for personal injury, death,
property damage, delays, demurrage, loss of profit, lost revenues, or any other
consequential or punitive damages of any kind whatsoever, irrespective of the
basis of such claims and even if such claims should arise out of Builder's sole
fault, negligence, breach of this Contract, or strict liability.

         As to the installation of all third-party supplied components,
materials or equipment, if the manufacturer or supplier has a representative at
the job site during such installation, and if the installation is completed to
the satisfaction of such representative, with all requirements of such
representative having been satisfied by Builder, it shall be conclusively
presumed that such installation has been completed by Builder in accordance
with the manufacturer's recommendations, in a proper and satisfactory manner.

         Builder does not warrant that any equipment or materials purchased by
it from a supplier or manufacturer for installation in the Vessel is free from
manufacturers' defects and deficiencies and Owner specifically releases Builder
from any such implied warranty of fitness or workmanship or freedom from
defects relating thereto. To the extent available, Builder agrees to transfer
and assign to Owner, without warranty of Builder with respect thereto, any
warranties relative to material, equipment and/or labor furnished by others.
Should Owner be required to enforce any such warranty, Builder will cooperate
with Owner's efforts, short of instituting legal action on Owner's behalf
and/or incurring other legal fees.

         Nothing contained herein shall obligate Builder at any time to repair
or replace the Vessel, or any component part thereof, where such repair and/or
replacement is caused, in whole or in part, by the negligent operation or
maintenance of the Vessel, or its equipment, by Owner or owner's agents,
employees or representatives.

         With respect to paint, Builder warrants that it will purchase paint of
good marine quality and that it will apply the paint in





                                       12
<PAGE>   13
accordance with the manufacturer's specifications and recommendations, and
Builder makes no warranty, express or implied, with respect to the fitness of
the paint or the manufacturer's specifications and recommendations.

         For any claim for damages to or loss of the Vessel, and/or damages to
persons and/or property (including, but not limited to claims, demands, or
actions for bodily injury, illness, disease, death, loss of service, loss of
society, maintenance and cure, wages or property) made as a result of any
defect in the Vessel, or any component parts thereof, after the said Warranty
Period, Owner shall have no claim or actions whatsoever against Builder,
regardless of any negligence, tort, fault, strict liability or otherwise of
Builder, its employees or sub-contractors, and Owner hereby waives and releases
Builder and its employees and sub-contractors from and against any and all
liability and any and all damages resulting therefrom, including, but not
limited to, for personal injury, death, property damage, damage to and/or loss
of the Vessel, delay, demurrage, loss of profits, loss of use, or any other
consequential or punitive damages of any kind, whether such claim is based in
contract, redhibition, negligence, strict liability, or otherwise, arising out
of any defect and/or negligent design, the selection or choice of
specifications and/or materials and/or component parts, manufacture,
construction, fabrication, workmanship, labor and/or installation of equipment,
materials and/or components or from any unseaworthy condition or any other
defective condition of the Vessel, it being specifically understood and agreed
that any such defects reported and/or occurring after the Warranty Period and
all damages, loss of profits, demurrages, delay, losses of use or other
consequential or punitive damage of any kind whatsoever resulting therefrom,
shall not be the responsibility of Builder, but shall be borne exclusively by
Owner.

         "THIS WARRANTY IS EXPRESSLY IN LIEU OF ALL OTHER WARRANTIES EXPRESS OR
         IMPLIED, INCLUDING ANY WARRANTY OF MERCHANTABILITY OR THAT THE
         VESSELS, MATERIAL OR SERVICES ARE FIT FOR ANY PARTICULAR PURPOSE OR

property damage to the Vessel, its components, and all Owner-furnished
equipment delivered to Builder's yard. To the extent of any property damage or
loss during such period to the Vessel, the work, the components, or the

         Partial losses, if any, shall be payable to Builder and the proceeds
thereof devoted by Builder to the repair and/or replacement of the damage.
Builder shall advise Owner promptly of any such occurrence. In the event that
an "actual total loss" or a "constructive total loss" (as these terms are
defined in the Builder's Risk Policy) should occur prior to the Vessel being
complete and ready for delivery, Owner shall be reimbursed out of the proceeds
of each policy all progress payments made to Builder and the cost of any Owner
furnished equipment or materials destroyed as a result of such total loss. All
other proceeds of the policy shall be paid to Builder. Following payment of
such insurance proceeds upon a total loss, Builder shall have the option, in
its sole discretion, either to terminate this Contract or to reinstate the
Contract and to reconstruct the Vessel pursuant to the terms of the Contract,
with completion being accomplished within a period of time equal to the time
originally allowed under the Contract.

Builder, irrespective of the basis of such claims and even if such claims
should arise out of the sole fault, negligence, strict liability or breach of
Contract of Owner.

         Similarly, Owner agrees to fully protect, defend, indemnify and hold
