REGISTRATION STATEMENT RELATING TO THESE SECURITIES HAS BEEN FILED WITH THE
SECURITIES AND EXCHANGE COMMISSION. THESE SECURITIES MAY NOT BE SOLD NOR MAY
OFFERS TO BUY BE ACCEPTED PRIOR TO THE TIME THE REGISTRATION STATEMENT BECOMES
EFFECTIVE. THIS PROSPECTUS SHALL NOT CONSTITUTE AN OFFER TO SELL OR THE
SOLICITATION OF AN OFFER TO BUY NOR SHALL THERE BE ANY SALE OF THESE SECURITIES
IN ANY STATE IN WHICH SUCH OFFER, SOLICITATION OR SALE WOULD BE UNLAWFUL PRIOR
TO REGISTRATION OR QUALIFICATION UNDER THE SECURITIES LAWS OF ANY SUCH STATE.

PROSPECTUS
 
                            POOL ENERGY SERVICES CO.
 
        OFFER TO EXCHANGE ITS 8 5/8% SENIOR SUBORDINATED NOTES DUE 2008,
           SERIES B FOR ANY AND ALL OF ITS OUTSTANDING 8 5/8% SENIOR
                     SUBORDINATED NOTES DUE 2008, SERIES A.
 
THE EXCHANGE OFFER AND WITHDRAWAL OF RIGHTS THEREUNDER WILL EXPIRE AT 5:00 P.M.,
      NEW YORK CITY TIME, ON [                  ], 1998, UNLESS EXTENDED.
 
     Pool Energy Services Co., a Texas corporation (the "Company"), hereby
offers, upon the terms and subject to the conditions set forth in this
Prospectus and the accompanying Letter of Transmittal (the "Letter of
Transmittal" and together with this Prospectus, the "Exchange Offer"), to
exchange its 8 5/8% Senior Subordinated Notes due 2008, Series B (the "New
Notes") which have been registered under the Securities Act of 1933, as amended
(the "Securities Act") pursuant to a Registration Statement (as defined herein)
of which this Prospectus constitutes a part, for any and all of its outstanding
8 5/8% Senior Subordinated Notes due 2008, Series A (the "Old Notes," and,
together with the New Notes, the "Notes"), of which $150,000,000 principal
amount is outstanding. The Exchange Offer is not conditioned upon any minimum
aggregate principal amount of Old Notes being tendered for exchange. However,
the Exchange Offer is subject to the absence of certain conditions which may be
waived by the Company. See "The Exchange Offer -- Certain Conditions to the
Exchange Offer." Subject to the absence or waiver of such conditions, the
Company will accept for exchange any and all Old Notes validly tendered on or
prior to 5:00 p.m., New York City time, on                     , 1998, unless
the Exchange Offer is extended (the "Expiration Date"). Old Notes may be
tendered only in integral multiples of $1,000. The date of acceptance and
exchange of the Old Notes (the "Exchange Date") will be the fourth business day
following the Expiration Date, unless an earlier date is selected by the
Company. Old Notes tendered pursuant to the Exchange Offer may be withdrawn at
any time prior to 5:00 p.m., New York City time, on the Expiration Date;
otherwise such tenders are irrevocable. The New Notes will be issued and
delivered promptly after the Exchange Date.
 
     The terms of the New Notes are identical in all material respects to the
terms of the Old Notes, except that the New Notes have been registered under the
Securities Act and are generally freely transferable by holders thereof and are
issued without any covenant by the Company regarding registration under the
Securities Act. See "The Exchange Offer -- Resale of New Notes." The New Notes
will evidence the same debt as the Old Notes and will be issued under and be
entitled to the benefits of the Indenture (as defined herein). For a complete
description of the terms of the New Notes, see "Description of Notes." There
will be no cash proceeds to the Company from this Exchange Offer.

THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
    EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS
       THE SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES
          COMMISSION PASSED UPON THE ACCURACY OR
               ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION
                     TO THE CONTRARY IS A CRIMINAL OFFENSE.
 
             THE DATE OF THIS PROSPECTUS IS                , 1998.

(Continued from cover page)
 
     As with the Old Notes, interest on the New Notes is payable semi-annually
on April 1 and October 1 of each year, commencing October 1, 1998. The Notes
will be redeemable at the option of the Company, in whole or in part, at any
time on or after April 1, 2003, at the redemption prices set forth herein. The
Company may also redeem up to 35% of the aggregate principal amount of the Notes
at its option, from time to time on or prior to April 1, 2001, at a redemption
price equal to 108.625% of the principal amount thereof, plus accrued and unpaid
interest and Special Interest (as defined herein), if any, to the redemption
date, with the net proceeds of one or more Equity Offerings (as defined herein);
provided, that at least $97.5 million of the aggregate principal amount of Notes
remains outstanding after such redemption. Upon the occurrence of a Change of
Control (as defined herein), the Company will be required to make an offer to
repurchase all or any part of each holder's Notes at a price equal to 101% of
the aggregate amount thereof, plus accrued and unpaid interest and Special
Interest, if any, to the date of purchase.
 
     The Notes are general unsecured obligations of the Company and will be
unconditionally guaranteed, jointly and severally on an unsecured senior
subordinated basis (the "Note Guarantees"), by each of the Subsidiary Guarantors
(as defined herein) to the extent set forth in the Note Guarantees. The New
Notes and each Note Guarantee will be subordinated to all Senior Indebtedness
(as defined herein) of the Company and the applicable Subsidiary Guarantors,
including obligations under the Credit Agreement (as defined herein). As of
March 31, 1998, the Company had approximately $19.5 million of Senior
Indebtedness (excluding letters of credit, operating leases and other contingent
liabilities). The indenture pursuant to which the New Notes will be issued
permits the Company and its subsidiaries (including the Subsidiary Guarantors)
to incur additional indebtedness, subject to certain limitations.
 
     The New Notes are being offered hereunder in order to satisfy certain
obligations of the Company and the Subsidiary Guarantors contained in the
Registration Rights Agreement dated March 31, 1998 (the "Registration Rights
Agreement"), among the Company, the Subsidiary Guarantors and SBC Warburg Dillon
Read Inc., Morgan Stanley & Co. Incorporated and Johnson Rice & Company L.L.C.
(the "Initial Purchasers"), with respect to the initial sale of the Old Notes.
The Old Notes were originally issued and sold on March 31, 1998, (the "Notes
Offering") in transactions that were not registered under the Securities Act in
reliance upon the exemption provided in Section 4(2) of the Securities Act. The
Initial Purchasers subsequently resold the Old Notes to "qualified institutional
buyers" in reliance upon Rule 144A under the Securities Act and pursuant to
offers and sales that occurred outside the United States within the meaning of
Regulation S under the Securities Act. Accordingly, the Old Notes may not be
reoffered, resold or otherwise transferred unless they are registered under the
Securities Act or unless an applicable exemption from the registration
requirements of the Securities Act is available. See "The Exchange
Offer -- Purpose of the Exchange Offer."
 
     Based on existing interpretations of the staff of the Securities and
Exchange Commission (the "Commission" or "SEC") issued to third-parties, the
Company believes that New Notes issued pursuant to the Exchange Offer in
exchange for Old Notes may be offered for resale, resold and otherwise
transferred by holders thereof (other than any such holder which is an
"affiliate" of the Company within the meaning of Rule 405 under the Securities
Act) without compliance with the registration and prospectus delivery
requirements of the Securities Act, provided that such New Notes are acquired in
the ordinary course of such holders' business and such holders are not engaged
in, have no arrangement with any person to participate in, and do not intend to
engage in any public distribution of the New Notes. Each broker-dealer that
receives New Notes for its own account pursuant to the Exchange Offer must
acknowledge that it will deliver a resale prospectus in connection with any
resale of such New Notes. This Prospectus, as it may be amended or supplemented
from time to time, may be used by a broker-dealer in connection with resales of
New Notes. The Company has agreed that, for such period of time as such
broker-dealers must comply with the prospectus delivery requirements of the
Securities Act in order to resell the Notes, it will make this Prospectus
available to any broker-dealer for use in connection with any such resale. See
"Plan of Distribution."
 
     The New Notes will constitute a new issue of securities with no established
trading market. The Company does not intend to list any Notes on a national
securities exchange or to apply for quotation of any
<PAGE>   5
(Continued from cover page)
 
Notes through the National Association of Securities Dealers Automated Quotation
System. Any Old Notes not tendered and accepted in the Exchange Offer will
remain outstanding. To the extent that Old Notes are tendered and accepted in
the Exchange Offer, a holder's ability to sell untendered and tendered but
unaccepted Old Notes could be adversely affected. Following consummation of the
Exchange Offer, the holders of Old Notes will continue to be subject to the
existing restrictions on transfers thereof, and the Company will have no further
obligation to such holders to provide for the registration under the Securities
Act of the Old Notes held by them except if a holder of Old Notes shall notify
the Company, within 20 business days following the consummation of the Exchange
Offer, that (i) such holder was prohibited by law or the policy of the
Commission from participating in the Exchange Offer, or (ii) such holder may not
resell the New Notes acquired by it in the Exchange Offer to the public without
delivering a prospectus, and this Prospectus (including any amendment or
supplement thereto) is not appropriate or available for such resales by such
holder. See "The Exchange Offer -- Purpose of the Exchange Offer." No assurance
can be given as to the liquidity of the trading market for either the Old Notes
or the New Notes.
 
     Holders of Old Notes whose Old Notes are not tendered and accepted in the
Exchange Offer will continue to hold such Old Notes and will be entitled to all
the rights and preferences and will be subject to the limitations applicable
thereto under the Indenture, and with respect to transfer, under the Securities
Act. The Company will not receive any proceeds from the Exchange Offer and will
pay all the expenses incident to the Exchange Offer. Any Old Notes not accepted
for exchange for any reason will be returned without expense to the tendering
holders thereof as promptly as practicable after the expiration or termination
of the Exchange Offer. See "The Exchange Offer." There is no public market for
the Old Notes. The New Notes will not be listed on any securities exchange, but
the Old Notes are included in the Private Offerings, Resales and Trading through
Automated Linkages ("PORTAL") Market for trading among "qualified institutional
buyers." There can be no assurance that an active trading market for the New
Notes will develop. To the extent that a market for the New Notes does develop,
the market value of the New Notes will depend on market conditions (such as
yields on alternative investments), general economic conditions, the Company's
financial condition and certain other factors. Such conditions might cause the
New Notes, to the extent that they are traded, to trade at a significant
discount from face value. See "Risk Factors -- Absence of Prior Public Market
for New Notes."
 
                          NEW HAMPSHIRE RESIDENTS ONLY
 
     Neither the fact that a registration statement or an application for a
license has been filed under Chapter 421-B of the New Hampshire Revised Statutes
with the State of New Hampshire nor the fact that a security is effectively
registered or a person is licensed in the State of New Hampshire constitutes a
finding by the Secretary of State that any document filed under Chapter 421-B of
the New Hampshire Statutes is true, complete and not misleading. Neither any
such fact nor the fact that an exemption or exception is available for a
security or a transaction means that the Secretary of State has passed in any
way upon the merits or qualifications of, or recommended or given approval to,
any person, security or transaction. It is unlawful to make, or cause to be
made, to any prospective purchaser, customer or client any representation
inconsistent with the provisions of this paragraph.

     The following summary is qualified in its entirety, and should be read in
conjunction with, the financial statements and more detailed information
included elsewhere herein or incorporated by reference in this Prospectus.
Unless the context requires otherwise or otherwise indicated, references to the
"Company" means Pool Energy Services Co., it subsidiaries and its unconsolidated
affiliates. Unless otherwise indicated, all pro forma information herein assumes
that the Company's acquisition (the "Acquisition" or the "Sea Mar Acquisition")
of Sea Mar, Inc. ("Sea Mar") occurred at the beginning of the periods to which
such information relates.
 
                                  THE COMPANY
 
GENERAL
 
     Pool Energy Services Co. is a leading worldwide provider of well-servicing,
workover and drilling rig services and related transportation services for both
land and offshore markets to a diverse group of multi-national, foreign national
and independent oil and natural gas producers. The Company performs the ongoing
maintenance and major overhauls necessary to optimize the level of production
from existing oil and natural gas wells and provides certain ancillary services
during the drilling and completion of new oil and natural gas wells. The Company
also provides contract drilling services in Alaska, the Gulf of Mexico, certain
international locations and on occasion in the lower forty-eight states.
Typically, the Company provides a well-servicing, workover or drilling rig, the
crew to operate the rig and such other specialized equipment as may be needed to
meet a customer's requirements. In addition, the Company owns and operates a
fleet of offshore support vessels that provides marine transportation of
drilling materials, supplies and crews for offshore rig operations and support
for other offshore facilities.
 
     As of March 31, 1998, the Company's worldwide rig fleet included 791 land
well-servicing/workover rigs, 27 land drilling rigs and 27 offshore rigs (15
platform workover rigs, five platform drilling rigs and seven jack-up rigs). The
Company also owns or leases and operates 370 fluid hauling trucks, 1,060 fluid
storage tanks, 14 salt water disposal wells and other auxiliary equipment used
in its domestic operations. The Company also operates a fleet of 23 support
vessels to complement its offshore rig fleet.
 
     The Company operates both domestically and internationally. In the United
States, the Company operates in several oil and natural gas producing states,
with specific concentration onshore in Texas, California, Oklahoma, New Mexico,
North Dakota, Montana, Utah and Alaska, and offshore in the Gulf of Mexico,
offshore California and in the Cook Inlet of Alaska. Revenues from domestic
operations represented approximately 85% of the Company's pro forma 1997
revenues. International markets where the Company has an established presence
include land operations in Argentina, Ecuador, Guatemala, Oman, Pakistan and
Saudi Arabia and offshore operations in Australia, Malaysia and Saudi Arabia.
Revenues from international operations represented approximately 15% of the
Company's pro forma 1997 revenues.
 
     The Company is a Texas corporation with its principal offices located at
10375 Richmond Avenue, Houston, Texas 77042. Its telephone number is (713)
954-3000.
 
BUSINESS STRATEGY
 
     The Company's business strategy is to further strengthen its competitive
position and market share in the oilfield services industry, in order to achieve
growth in revenues, earnings and EBITDA (as defined herein). Key components of
the Company's business strategy include:
 
     - Pursuing expansion opportunities in existing core market areas through
       selective acquisitions that result in an expanded market presence and in
       consolidation cost savings.
 
     - Upgrading and enhancing the capabilities of the Company's existing rig
       fleet and constructing specialized rigs and equipment to operate in
       markets with high levels of activity and strong pricing fundamentals.
 
                                        1
<PAGE>   9
 
     - Offering a broad and integrated array of additional services and
       equipment that complement the Company's businesses in its existing
       locations.
 
     - Entering new foreign markets that offer significant development and
       production activity.
 
IMPLEMENTATION OF BUSINESS STRATEGY
 
     The Company has been significantly expanding its core operations through
acquisitions and rig enhancement. In 1997, the Company expanded its domestic
land well-servicing operations with purchases of 111 well-serving rigs, 128
oilfield trucks, 430 fluid storage tanks, five coiled tubing units and related
assets for an aggregate of approximately $50 million. The Company also acquired
an offshore jackup workover rig for its Gulf of Mexico operations for $8 million
and its Saudi Arabia affiliate purchased four land rigs for $9 million. During
1998, the Company has completed the construction of a large offshore platform
drilling rig and has made substantial modifications to four land drilling rigs
at an aggregate estimated cost of $38 million. Such rigs began operating during
1998 in Alaska, the Gulf of Mexico and Saudi Arabia under long-term contracts.
The Company's Alaska operation is in the process of constructing a new land
drilling rig and substantially modifying another land drilling rig at an
aggregate estimated cost of $29 million. Such rigs are committed under long-term
contracts and are expected to be in operation commencing in late 1998 and early
1999, respectively. In addition, with the Sea Mar Acquisition, the Company
broadened the range of services it offers to its customers to include offshore
support vessel services.
 
                              RECENT TRANSACTIONS
 
SEA MAR ACQUISITION
 
     The Company agreed, on February 10, 1998, to acquire all of the outstanding
capital stock of Sea Mar. On March 31, 1998, the Company acquired Sea Mar for
approximately $75.9 million in cash (including an estimated $14.7 million in
post-closing purchase price adjustments) and 1,538,462 common shares of the
Company. In addition, the Company has agreed to pay additional cash
consideration contingent upon Sea Mar exceeding EBITDA (as defined in the stock
purchase agreement for the Sea Mar Acquisition) 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 Company also repaid Sea Mar's existing debt of $15.7
million. The Sea Mar Acquisition was accounted for under the purchase method of
accounting.
 
     Sea Mar operates 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 23 support vessels,
including one anchor handling/tug supply vessel, 13 supply vessels, seven
mini-supply vessels and two research vessels. In addition, during 1997 a
contract was entered into with a marine shipbuilder for the construction of ten
additional vessels at an estimated aggregate cost of $77.6 million, net of
deposits. These new vessels are scheduled to be delivered between late 1998 and
early 2000.
 
NOTES OFFERING AND AMENDMENT OF CREDIT AGREEMENT
 
     Initially, the Company considered funding the Sea Mar Acquisition through a
private placement of the Company's debt securities or through borrowings under
the Company's existing syndicated bank revolving credit agreement (the "Credit
Agreement"). In contemplation of the latter possibility and in view of the
Company's increased capital requirements following the Sea Mar Acquisition, the
Credit Agreement was amended to increase the maximum availability thereunder
from $130 million to $180 million. On March 31, 1998, the Company completed a
private placement of $150,000,000 aggregate principal amount of the Old Notes
pursuant to a purchase agreement, dated March 26, 1998 by and among SBC Warburg
Dillon Read Inc., Morgan Stanley & Co. Incorporated, and Johnson Rice & Company
L.L.C. and the Company and the
                                        2
<PAGE>   10
 
Subsidiary Guarantors. The net proceeds of the Notes Offering were used to
effect the Sea Mar Acquisition, to repay outstanding debt of Sea Mar and to
reduce the outstanding balance under the Credit Agreement. The Old Notes were
issued pursuant to an indenture (the "Indenture") dated March 31, 1998, by and
between the Company, the Subsidiary Guarantors and Marine Midland Bank as
trustee (the "Trustee").

                             tender should contact such registered holder
                             promptly and instruct such registered holder to

                             owner must, prior to completing and executing the

                             either make appropriate arrangements to register

                             power from the registered holder. The transfer of
                             registered ownership may take considerable time.
                             See "The Exchange Offer -- Procedures for Tendering

                             applicable thereto under the Indenture, except for
                             any such rights under the Registration Rights
                             Agreement that by their terms terminate or cease to
                             have further effectiveness as a result of the
                             making of, and the acceptance for exchange of all
                             validly tendered Old Notes pursuant to the

                             Exchange Offer. Holders of Old Notes who do not
                             exchange their Old Notes for New Notes pursuant to
                             the Exchange Offer will continue to be subject to
                             the restrictions on transfer of such Old Notes as
                             set forth in the legend therein and, except in
                             limited circumstances, will no longer have any
                             registration rights with respect to the Old Notes.
                             In general, the Old Notes may not be offered or
                             sold, unless registered under the Securities Act,
                             except pursuant to an exemption from, or in a
                             transaction not subject to, the Securities Act and
                             applicable state securities laws. The Company does
                             not currently anticipate that it will register the
                             Old Notes under the Securities Act. To the extent
                             that Old Notes are tendered and accepted in the
                             Exchange Offer, the trading market for untendered
                             or tendered but unaccepted Old Notes could be
                             adversely affected. See "The Exchange
                             Offer -- Consequences of Failure to Exchange."
 
Registration Rights........  The Company and the Subsidiary Guarantors entered
                             into a Registration Rights Agreement dated as of
                             March 31, 1998 with the Initial Purchasers, for the
                             benefit of all holders of Old Notes, in which it
                             agreed to make the Exchange Offer. The Registration
                             Rights Agreement provides that, among other
                             conditions, if the Company fails to consummate the
                             Exchange Offer on or prior to 45 days following the
                             effectiveness date of the Exchange Offer
                             Registration Statement, the Company will file a
                             shelf registration statement (the "Shelf
                             Registration Statement") to cover resales of New
                             Notes by Holders who provide certain information
                             required for inclusion in the Shelf Registration
                             Statement, and who agree to be bound by the terms
                             of the Registration Rights Agreement. Upon a
                             Registration Default (as defined herein), the
                             Company will be required to pay Special Interest
                             (as defined herein) to the affected holders of the
                             Notes. See "Exchange Offer; Registration Rights."
 
Exchange Agent.............  Marine Midland Bank is serving as exchange agent
                             (the "Exchange Agent") in connection with the
                             Exchange Offer. See "The Exchange Offer -- Exchange
                             Agent."
 
Resale of New Notes........  Based upon interpretations by the staff of the SEC
                             issued to third parties, the Company believes the
                             New Notes issued pursuant to the Exchange Offer in
                             exchange for Old Notes may be offered for resale,
                             resold and otherwise transferred by holders thereof
                             (other than any holder which is a broker-dealer or
                             an "affiliate" of the Company within the meaning of
                             Rule 405 under the Securities Act) without
                             compliance with the registration and prospectus
                             delivery provisions of the Securities Act provided
                             that such New Notes are acquired in the ordinary
                             course of business and such holders have no
                             arrangement with any person to participate in the
                             distribution of such New Notes. Each broker-dealer
                             that receives New Notes for its own account
                             pursuant to the Exchange Offer must acknowledge
                             that it will deliver a prospectus in connection
                             with a resale of such New Notes. This Prospectus,
                             as it may be amended or supplemented from time to
                             time, may be used by such broker-dealers in
                             connection with such resales. See "The Exchange
                             Offer -- Resale of New Notes."

                             herein) of the Company (including the Company's
                             obligations under the Credit Agreement). On March
                             31, 1998 after the Sea Mar Acquisition and the
                             Notes Offering and the application of net proceeds
                             therefrom, the Company had approximately $19.5
                             million of Senior Indebtedness outstanding
                             (excluding letters of credit, operating leases and
                             other contingent liabilities).

                             unsecured senior subordinated basis by each of the
                             domestic Restricted Subsidiaries (as defined
                             herein) of the Company (the "Subsidiary Guarantors"
                             or "Guarantors"). Each of the Note Guarantees is a
                             general unsecured obligation of the Subsidiary
                             Guarantor thereof, subordinated in right of payment
                             to the Subsidiary Guarantor's guarantee of the
                             Company's obligations under the Credit Agreement
                             and to all other Senior Indebtedness of such
                             Subsidiary Guarantor.
 
Optional Redemption........  The Notes are redeemable at the option of the
                             Company, in whole or in part, at any time on or
                             after April 1, 2003, at the redemption prices set
                             forth herein, plus accrued and unpaid interest and
                             Special Interest (as defined herein), if any, to
                             the redemption date. The Company may also redeem up
                             to 35% of the aggregate principal amount of the
                             Notes at its option, from time to time prior to
                             April 1, 2001, at a redemption price equal to
                             108.625% of the principal amount thereof, plus
                             accrued and unpaid interest and Special Interest,
                             if any, to the redemption date, with the net
                             proceeds of one or more Equity Offerings (as
                             defined herein); provided, however, that at least
                             $97.5 million of the aggregate principal amount of
                             Notes remains outstanding following each such
                             redemption. See "Description of Notes -- Optional
                             Redemption of the Notes."
 
Change of Control..........  Upon the occurrence of a Change of Control, the
                             Company will be required to offer to purchase all
                             or any part of each holder's Notes at a price equal
                             to 101% of the principal amount thereof, plus
                             accrued and unpaid interest and Special Interest,
                             if any, to the date of purchase. There can be no
                             assurance that the Company will have the financial
                             resources necessary, or be permitted by its debt or
                             other agreements, to purchase the Notes upon a
                             Change of Control. See "Description of
                             Notes -- Change of Control."

Certain Covenants..........  The Indenture governing the Notes contains certain
                             covenants that, among other things, limit the
                             ability of the Company and the Restricted
                             Subsidiaries (as defined herein) to incur
                             additional indebtedness; issue capital stock of
                             Restricted Subsidiaries; pay dividends or make
                             other restricted payments; incur liens; enter into
                             certain transactions with affiliates; or enter into
                             certain mergers or consolidations or sell all or
                             substantially all of the assets of the Company and
                             its subsidiaries. These covenants are subject to a
                             number of significant exceptions and
                             qualifications. See "Description of
                             Notes -- Certain Covenants."
 
Absence of Public Market...  There is no public market for the New Notes, and
                             the New Notes will not be listed on any securities
                             exchange. The Company has been advised by the
                             Initial Purchasers, that following consummation of
                             the Exchange Offer, the Initial Purchasers intend
                             to make a market in the New Notes; however, any
                             market making may be discontinued at any time
                             without notice. If an active public market does not
                             develop, the market price and liquidity of the New
                             Notes may be adversely affected. See "Risk
                             Factors." For definitions of certain capitalized
                             terms used herein, see "Description of Notes."
 
                                  RISK FACTORS
 
     For a discussion of certain factors that should be considered in connection
with an investment in the New Notes, see "Risk Factors."

(1) See Note 7 of Notes to Consolidated Financial Statements for a discussion of
    the $23.6 million pretax ($15.3 million, or $1.13 per share, after-tax)
    provision for leasehold impairment.
 
(2) EBITDA (earnings before interest, taxes, depreciation and amortization and
    minority interest) is not a measure of financial performance under generally
    accepted accounting standards, but is presented here to provide additional
    information about the Company's operations. EBITDA should not be considered
    as an alternative to net income as an indicator of the Company's operating
    performance or as an alternative to cash flows as a better measure of
    liquidity. EBITDA presented above may not be comparable to similarly titled
    measures of other companies. Excluding the $23.6 million non-cash pretax
    provision for leasehold impairment, the 1994 EBITDA would be $16.5 million
    (see Note 7 of Notes to Consolidated Financial Statements).
 
(3) Excluding acquisitions of businesses.
 
(4) The ratio of earnings to fixed charges has been computed by dividing
    earnings available for fixed charges (earnings before income taxes plus
    fixed charges less capitalized interest) by fixed charges (interest expense
    plus capitalized interest plus the portion of operating lease rental expense
    that represents the interest factor which is deemed to be one-third of
    rentals). In the year ended December 31, 1994, earnings (following a
    significant one-time non-cash charge for leasehold impairment) were
    inadequate to cover fixed charges by $3.3 million.
 
(5) Cash interest expense represents total interest expense ($3,927 for the pro
    forma quarter ended March 31, 1998 and $16,437 for the pro forma year ended
    December 31, 1997) less amortization of deferred financing costs and other
    non-cash interest charges ($359 for the pro forma quarter ended March 31,
    1998 and $1,980 for the pro forma year ended December 31, 1997).

                                  RISK FACTORS
 
     In evaluating the exchange offer, holders of the Old Notes should carefully
consider the following factors in addition to those discussed elsewhere in this
prospectus prior to accepting the Exchange Offer. Holders of Old Notes should
also consider that such factors are generally applicable to the Old Notes as
well as the New Notes. The Old Notes and the New Notes are collectively referred
to herein as the "Notes."
 
SUBSTANTIAL LEVERAGE
 
     As a result of the Sea Mar Acquisition and the Notes Offering, the Company
has substantial leverage. At March 31, 1998, giving effect to the completion of
the Sea Mar Acquisition, the Notes Offering, and the application of net proceeds
therefrom, the total debt of the Company was $170 million and its stockholders'
equity was $276 million. Subject to the restrictions in the Indenture and the
Credit Agreement, the Company may incur additional indebtedness from time to
time to provide working capital, to finance acquisitions or capital expenditures
and for other corporate purposes. The level of the Company's indebtedness may
affect owners of the Notes in a number of ways including: (i) a substantial
portion of the Company's cash flow from operations must be dedicated to debt
service and will not be available for other purposes, (ii) the Company's ability
to obtain additional debt financing in the future for working capital,
acquisitions or capital expenditures may be limited, (iii) certain of the
Company's indebtedness contains financial and other restrictive covenants which,
if breached, could result in an event of default under such indebtedness, (iv)
the Company's borrowings under the Credit Agreement are and will continue to be
at variable rates of interest, which causes the Company to be vulnerable to
increases in interest rates and (v) the Company's level of indebtedness could
limit its flexibility in planning for and reacting to, and make it more
vulnerable to, competitive pressures and changes in industry and economic
conditions generally.
 
     The Company's ability to pay interest and principal on the Notes and to
satisfy its other debt obligations will depend upon its future operating
performance. Future operating performance will be affected by prevailing
economic conditions and financial, business and other factors, many of which are
beyond the Company's control. Based on the current level of operations and
anticipated future growth, the Company believes that its operating cash flow,
together with borrowings under the Credit Agreement, will be sufficient to meet
its operating expenses and its capital debt service requirements. There can be
no assurance that the Company's business will continue to generate cash flow at
or above current levels or that anticipated future growth can be achieved. If
the Company is unable to generate sufficient cash flow to service its
indebtedness and fund its capital or other expenditures, it will be forced to
adopt an alternative strategy that may include reducing or delaying capital
expenditures, selling assets or refinancing of its indebtedness (including the
Notes), or seeking additional equity or debt capital. There can be no assurance
that any of these strategies could be effected on satisfactory terms, if at all,
particularly in view of the Company's substantial leverage following the Sea Mar
Acquisition and the Notes Offering.
 
RESTRICTIVE COVENANTS
 
     The terms of the Credit Agreement, the Indenture and the other agreements
governing the Company's indebtedness impose operating and financing restrictions
on the Company. Such restrictions affect, and in many respects limit or
prohibit, among other things, the ability of the Company to incur additional
indebtedness, pay dividends or repurchase stock or make other distributions,
create liens, make certain investments, sell assets, or enter into mergers or
consolidations. The Credit Agreement requires the Company to comply with certain
financial ratios and tests under which the Company is required to maintain a
minimum net worth, a maximum interest coverage ratio, a minimum fixed charge
coverage ratio, a maximum leverage ratio and a maximum debt-to-equity ratio.
During the past year, the Company has been in compliance with each of these
covenants and has not been at risk of not being in compliance. The restrictions
imposed by the Credit Agreement could limit the ability of the Company to plan
for or react to market conditions or meet extraordinary capital needs or
otherwise could restrict corporate activities. There can be no assurance that
such restrictions will not adversely affect the Company's ability to finance its
future operations or capital needs or to engage in other business activities
that would be in the interest of the Company. Moreover, any default
 
                                       10
<PAGE>   18
 
under the documents governing the indebtedness of the Company could have a
significant adverse effect on the market value of the Notes.
 
HOLDING COMPANY STRUCTURE; EFFECTIVE SUBORDINATION
 
     The Company is a holding company whose only assets consist of ownership
interests in its subsidiaries. Consequently, the Company's ability to obtain
cash from its subsidiaries for the purpose of meeting its debt service
obligations, including the payment of principal and interest on the Notes,
depends on the earnings of its subsidiaries and its ability to receive funds
from such subsidiaries through dividends, repayment of intercompany notes, or
other payments. The ability of the Company's subsidiaries to pay dividends,
repay intercompany notes or make other advances of payments to the Company may
be subject to restrictions imposed by applicable law, tax considerations and the
terms of other agreements governing the Company's subsidiaries (including
restrictions imposed by the Credit Agreement).
 
     The payment of principal of and interest on, and any premium or other
amounts owing in respect of, the Notes is subordinated to the prior payment in
full of all existing and future Senior Indebtedness of the Company and the
Subsidiary Guarantors, including all amounts owing or guaranteed under the
Credit Agreement. In addition, the Notes are structurally subordinated to all
obligations (including trade payables and accrued liabilities) of the Company's
subsidiaries, other than any subsidiary that issues a Note Guarantee. None of
the Company's current or future foreign subsidiaries is required to provide a
Note Guarantee. In the event of a bankruptcy, liquidation, dissolution,
reorganization or similar proceeding with respect to the Company or a Subsidiary
Guarantor, assets of the Company or such Subsidiary Guarantor will be available
to pay obligations on the Notes or Note Guarantees only after all Senior
Indebtedness of the Company or the Subsidiary Guarantors, as applicable, has
been paid in full, and there can be no assurance that there will be sufficient
assets to pay amounts due on any or all of the Notes. In addition, neither the
Company nor any Subsidiary Guarantor may pay principal, premium, interest or
other amounts on account of the Notes or any Note Guarantee in the event of
payment default in respect of Designated Senior Debt (as defined herein), or in
the event of certain other defaults. See "Description of Notes
 -- Subordination." As of March 31, 1998, after giving effect to the Sea Mar
Acquisition and the Notes Offering, the Company had $19.5 million of Senior
Indebtedness outstanding (excluding letters of credit, operating leases and
other contingent liabilities).
 
VOLATILITY OF OIL AND NATURAL GAS MARKET
 
     Demand for the Company's services depends on conditions in the worldwide
oil and natural gas industry, particularly on the level of development,
production and exploration activity of, and the corresponding spending by, oil
and natural gas companies. Such activity and expenditure levels are directly
impacted by trends in oil and natural gas prices, expectations about future
prices, governmental regulations, global weather conditions (including the
effects of El Nino), worldwide political, military and economic conditions,
including the ability of the Organization of Petroleum Exporting Countries
("OPEC") to set and maintain production levels and prices, the level of
production by non-OPEC countries, the policies of various governments regarding
the exploration and development of their oil and natural gas reserves and the
level of demand for oil and natural gas in various countries and geographic
regions. These factors have contributed to, and are likely to continue to
contribute to, oil and natural gas price volatility. A substantial amount of the
Company's operations are in United States markets where, despite occasional
upturns, the demand for the Company's well-servicing, workover and production
services has at times been adversely affected by periods of weakness in oil and
natural gas prices during the past decade. Since October 1997, the average
prices of oil and natural gas have declined. Prolonged low oil or natural gas
prices would likely depress activity by producers and reduce the demand for the
Company's services. In addition, redeployment or reactivation of equipment or
new construction of equipment could adversely affect the Company's rates and
utilization levels, even in an environment of stronger oil and natural gas
prices and increased activity by producers.
 
INTERNATIONAL RISKS
 
     The Company's foreign operations are subject to various risks associated
with doing business in foreign countries, such as the possibility of armed
conflict and civil disturbance, political instability, the instability of
                                       11
<PAGE>   19
 
foreign economies, currency fluctuations and devaluations, adverse tax policies
and governmental activities that may limit or disrupt markets, restrict payments
or the movement of funds or result in the deprivation of contract rights or the
expropriation of property. Additionally, the ability of the Company to compete
overseas may be adversely affected by foreign governmental regulations that
encourage or mandate the hiring of local contractors, or by regulations that
require foreign contractors to employ citizens of, or purchase supplies from, a
particular jurisdiction.
 
     The Company is subject to taxation in many jurisdictions, and the final
determination of its tax liabilities involves the interpretation of the statutes
and requirements of various domestic and foreign taxing authorities. Foreign
income tax returns of foreign subsidiaries, unconsolidated affiliates and
related entities are routinely examined by foreign tax authorities and such
examinations may result in assessments of additional taxes and/or penalties.
 
RISKS OF FAILURE TO IDENTIFY OR SUCCESSFULLY INTEGRATE FUTURE ACQUISITION
TARGETS
 
     A significant portion of the Company's growth has resulted from the
acquisition of other oilfield services businesses and assets. There can be no
assurance, however, that the Company will be able to continue to identify
attractive acquisition opportunities at reasonable prices, negotiate acceptable
acquisition terms, obtain financing for acquisitions on satisfactory terms or
successfully acquire identified targets. In addition, there can be no assurance
that the Company will successfully integrate the operations and assets of any
acquired business with its own or that the Company's management will be able to
manage effectively the increased size of the Company or operate a new service
line. Any inability on the part of the Company to integrate and manage acquired
businesses could have a material adverse effect on the Company's results of
operations and financial condition.
 
     As indicated above under "Substantial Leverage," the ability of the Company
to pursue acquisition opportunities may be affected by limitations on its
financing flexibility imposed by the Credit Agreement and the Indenture.
Moreover, there can be no assurance that the competition for acquisition
opportunities in the industry will not escalate, thereby increasing the cost to
the Company of making further acquisitions or causing the Company to refrain
from making acquisitions. Acquisitions may result in increased depreciation and
amortization expense, increased interest expense, increased financial leverage
or decreased operating income, any of which could have a material adverse effect
on the Company's operating results.
 
SUPPLY VESSEL OPERATIONS
 
     Supply vessel operations are subject to a number of risks that could
adversely affect the Company's operating results. In addition to the risks
described under other captions in "Risk Factors," these risks include:
 
  Seasonality
 
     The Company may be affected by seasonal risks with respect to Sea Mar's
operations. Utilization rates for support vessels typically have reached their
lowest levels in the first quarter, when offshore marine activity generally
declines as oil and gas companies defer discretionary activity until more
favorable weather conditions are likely. Accordingly, the results of any one
quarter are not necessarily indicative of annual results or continuing trends.
 
  Age of Fleet
 
     As of March 31, 1998, the average age of Sea Mar's vessels (based on the
date of construction) was approximately 17.4 years. The industry expectation is
that normally after a vessel has been in service in excess of 30 years, repair,
vessel certification and maintenance costs may become no longer economically
justifiable. There can be no assurance that Sea Mar will be able to maintain its
fleet by extending the economic life of existing vessels through major
refurbishment or by acquiring new or used vessels.
 
                                       12
<PAGE>   20
 
  Risks of New Construction, Upgrade and Refurbishment Projects
 
     The Company intends to make significant expenditures to construct new
vessels and to construct, upgrade and refurbish, supply vessels and related
equipment. These projects are subject to cost overruns inherent in large
construction and refurbishment projects, including shipyard availability,
shortages of materials or skilled labor, unforeseen engineering problems, work
stoppages, weather interruptions, unanticipated cost increases, nonavailability
of necessary equipment and inability to obtain any of the requisite permits or
approvals. Significant delays could also have a material adverse effect on the
Company's marketing plans for such vessels. In addition, there is no assurance
as to the rates new vessels will earn when placed in service. Although Sea Mar
has entered into term contracts for four of the ten new vessels that it has
under construction, these contracts are subject to a pending legal dispute.
 
  Dependence on Key Personnel
 
     Sea Mar's operations are dependent in large part on the continued
employment of Mr. Al A. Gonsoulin as Sea Mar's Vice President and General
Manager. Mr. Gonsoulin was formerly the President and Chief Executive Officer of
Sea Mar and, in connection with the Sea Mar Acquisition, entered into a
three-year employment contract with the Company. The loss of Mr. Gonsoulin
before the end of this three-year period could adversely affect Sea Mar's
operations.
 
  Additional Risks
 
     The Sea Mar Acquisition also involved the assumption of potential
liabilities, disclosed or undisclosed, associated with the Sea Mar business. In
addition, there is the risk that the Sea Mar operations will not be able to be
successfully integrated into the Company. There can be no assurance that such
operations will ultimately have a positive impact on the Company, its financial
condition or results of operations.
 
COMPETITION
 
     Although the number of available rigs has substantially decreased over the
past ten years, the well-servicing, workover and drilling industry remains very
competitive. The number of rigs available for contracts continues to exceed
demand, resulting in keen price competition. Many contracts are awarded on a bid
basis, which further increases competition based on price. In all of the
Company's market areas, competitive factors also include the availability and
condition of equipment to meet both special and general customer needs; the
availability of trained personnel possessing the required specialized skills;
the overall quality of service and safety record; and domestically, the ability
to offer ancillary services such as fluid hauling, fluid storage tank rental and
salt water disposal.
 
     In addition, the Company faces significant competition with respect to the
operations of Sea Mar. The marine support services industry is highly
competitive. Competitive factors in the marine support services industry include
(i) price, (ii) service, including the reputation of vessel operators and crews,
(iii) availability of vessels of the types and sizes needed by the customer and
(iv) quality of vessels and related equipment.
 
OPERATING RISKS AND INSURANCE
 
     The Company's operations involve workers conducting activities with and
around machinery and equipment in close proximity to highly flammable oil and
natural gas, and are subject to hazards inherent in the oil and natural gas
industry, including, without limitation, blowouts, fires, explosions and other
casualties. Incidents involving such hazards can cause personal injury or loss
of life, damage to or destruction of property, including equipment, oil and
natural gas production and producing formations and to the environment, and
suspension of operations. The frequency and severity of such incidents affect
the Company's operating costs and its relationship with customers, employees and
regulators, and any significant increase in the frequency or severity of such
incidents, or the general level of compensation awards with respect thereto,
could affect the Company's ability to obtain insurance and could have a material
adverse effect on the Company. Although the Company has generally been able to
obtain insurance on terms it considers to be reasonable, there can be no
assurance that insurance will continue to be available on reasonable terms.
                                       13
<PAGE>   21
 
     The Company maintains insurance coverage of types and amounts that it
believes to be customary in the industry. The Company also endeavors to
negotiate contractual indemnification provisions in its contracts with customers
to cover risks which are customarily retained by the customer. It is possible,
however, that significant liabilities could arise that would not be covered, and
for which the applicable contract between the Company and its customer would not
provide indemnity protection to the Company for the particular loss involved.
Additionally, it is possible that liabilities could arise that would exceed
applicable policy limits. Liabilities for which the Company is not insured, or
which exceed the policy limits of applicable insurance, and for which the
Company is not otherwise contractually protected through indemnification by
customers, could have a material adverse effect on the Company.
 
     The Company is also subject to operating and insurance risks with respect
to the operations of Sea Mar. Marine support vessels are subject to operating
risks such as catastrophic marine disasters, adverse weather conditions,
mechanical failure, collisions, oil and hazardous substance spills and
navigation errors. The occurrence of any of these events may result in damages
to or loss of Sea Mar's vessels and such vessels' tow or cargo or other property
and injury to passengers and personnel. Such occurrences may also result in a
significant increase in operating costs or liability to third parties. Sea Mar
maintains insurance coverage against certain of these risks, which management
considers to be customary in the industry. There can be no assurance, however,
that Sea Mar's existing insurance coverage can be renewed at commercially
reasonable rates or that such coverage will be adequate to cover future claims
that may arise.
 
POSSIBLE IMPACT OF ENVIRONMENTAL REGULATION AND CLAIMS AND OTHER GOVERNMENTAL
REGULATIONS
 
     The Company's well-servicing, workover and production services operations
routinely involve the handling of significant amounts of waste materials, some
of which are classified as hazardous substances. The Company's operations and
facilities are subject to numerous state and federal environmental laws, rules
and regulations including, without limitation, laws concerning the containment
and disposal of hazardous substances, oil field waste and other waste materials,
the use of underground storage tanks and the use of underground injection wells.
Sea Mar's operations, like the Company's other operations, also are subject to
federal, state and local laws and regulations which control the discharge of
pollutants into the environment and which otherwise relate to environmental
protection. Sea Mar and the Company are also subject to other laws that regulate
the activities of offshore service vessels, require vessel owners and operators
to demonstrate financial and operational responsibility and provide for certain
limitations on the liability of vessel owners and operators. Failure to comply
with these laws, rules and regulations may result in civil and even criminal
actions against the Company.
 
     Laws protecting the environment generally have become more stringent than
in the past and are expected to continue to do so. Environmental laws and
regulations typically impose "strict liability," which means that in some
situations the Company could be exposed to liability for cleanup costs and other
damages as a result of conduct of the Company that was lawful at the time it
occurred or conduct of, or conditions caused by, prior operators or other third
parties. Cleanup costs, natural resource damages and other damages arising as a
result of environmental laws, and costs associated with changes in environmental
laws and regulations, could be substantial and could have a material adverse
effect on the Company's financial condition. From time to time, claims have been
made and litigation has been brought against the Company under such laws.
 
     Changes in federal and state environmental regulations may also negatively
impact oil and natural gas exploration and production companies, which in turn
could have a material adverse effect on the Company. For example, legislation
has been proposed from time to time in Congress which would reclassify oil and
natural gas production wastes as "hazardous wastes." If enacted, such
legislation could dramatically increase operating costs for domestic oil and
natural gas companies, and this could reduce the market for the Company's
services by making many wells and/or oilfields uneconomical to operate. To date,
such legislation has not made significant progress toward enactment.
 
     With respect to Sea Mar's operations, the Company is affected by additional
government regulations. Under the Merchant Marine Act of 1920, as amended, if
persons other than U.S. citizens own in the aggregate in excess of 25% of the
Company's outstanding stock, Sea Mar's U.S. flagged vessels would lose the
privilege
 
                                       14
<PAGE>   22
 
of engaging in the transportation of merchandise in the U.S. coastwise trade. In
addition, Sea Mar's operations are materially affected by federal, state and
local regulation, as well as certain international conventions and private
industry organizations. These regulations govern worker health and safety and
the manning, construction and operation of vessels. Private industry
organizations establish safety criteria and are authorized to investigate vessel
accidents and recommend approved safety standards. The failure to comply with
the requirements of any of these laws or the rules or regulations of these
agencies and organizations could have a material adverse effect on Sea Mar's
operations.
 
CHANGE OF CONTROL
 
     Upon the occurrence of a Change of Control (as defined herein), the Company
will be required to offer to purchase all of the outstanding Notes at 101% of
the principal amount thereof, plus accrued and unpaid interest (including
Special Interest, if any) to the date of purchase. There can be no assurance
that the Company will have sufficient funds available, will be able to raise
sufficient funds through a refinancing of the Notes, or will be permitted by its
other debt agreements to purchase the Notes upon the occurrence of a Change of
Control. In addition, a Change of Control may require the Company to offer to
purchase other outstanding indebtedness and would cause a default under the
Credit Agreement. The inability to purchase all of the tendered Notes would
constitute an Event of Default (as defined) under the Indenture. See
"Description of Notes  -- Change of Control." Under the Company's Shareholder
Rights Plan, in the event of a triggering event causing the rights thereunder to
become exercisable, the Company may be obligated to pay amounts to holders of
the rights that would exceed the Limitations on Restricted Payments covenant of
the Indenture and cause an event of default thereunder. See "Description of
Notes -- Certain Covenants" and Note 2 to the Company's Notes to Consolidated
Financial Statements.
 
     The Change of Control provision may not necessarily afford the holders of
Notes protection in the event of a highly leveraged transaction, including a
reorganization, restructuring, merger, or similar transaction involving the
Company that would adversely affect the holders because such transactions may
not involve a shift in voting power or beneficial ownership, may not involve a
shift of the required magnitude or may not otherwise fit within the definition
of Change of Control.
 
FRAUDULENT CONVEYANCE LAWS
 
     Various fraudulent conveyance laws enacted for the protection of creditors
may apply to a Subsidiary Guarantor's issuance of a Note Guarantee. To the
extent that a court were to find that (x) a Note Guarantee was incurred by a
Subsidiary Guarantor with intent to hinder, delay or defraud any present or
future creditor or the Subsidiary Guarantor contemplated insolvency with a
design to prefer one or more creditors to the exclusion in whole or in part of
others or (y) a Subsidiary Guarantor did not receive fair consideration or
reasonably equivalent value for issuing its Note Guarantee and such Subsidiary
Guarantor (i) was insolvent, (ii) was rendered insolvent by reason of the
issuance of such Note Guarantee, (iii) was engaged or about to engage in a
business or transaction for which the remaining assets of such Subsidiary
Guarantor constituted unreasonably small capital to carry on its business or
(iv) intended to incur, or believed that it would incur, debts beyond its
ability to pay such debts as they matured, the court could avoid or subordinate
such Note Guarantee in favor of the Subsidiary Guarantor's creditors. Among
other things, a legal challenge of a Note Guarantee on fraudulent conveyance
grounds may focus on the benefits, if any, realized by the Subsidiary Guarantor
as a result of the issuance by the Company of the Notes. The Indenture contains
a savings clause, which generally limits the obligations of each Subsidiary
Guarantor under a guarantee to the maximum amount as will, after giving effect
to all of the liabilities of such Subsidiary Guarantor, result in such
obligations not constituting a fraudulent conveyance. To the extent a Note
Guarantee of any Subsidiary Guarantor was avoided as a fraudulent conveyance or
held unenforceable for any other reason, holders of the Notes would cease to
have any claim against such Subsidiary Guarantor and would be creditors solely
of the Company and each Subsidiary Guarantor whose Note Guarantee was not
avoided or held unenforceable. In such event, the claims of the holders of the
Notes against the issuer of an invalid Note Guarantee would be subject to the
prior payment of all liabilities of such Subsidiary Guarantor. There can be no
assurance that,
 
                                       15
<PAGE>   23
 
after providing for all prior claims, there would be sufficient assets to
satisfy the claims of the holders of the Notes relating to any avoided portions
of any guarantees.
 
     The measure of insolvency for purposes of the foregoing considerations will
vary depending upon the law applied in any such proceeding. Generally, however,
a Subsidiary Guarantor may be considered insolvent if the sum of its debts,
including contingent liabilities, was greater than the fair market value of all
its assets at a fair valuation or if the present fair market value of its assets
was less than the amount that would be required to pay its probable liability on
its existing debts, including contingent liabilities, as they become absolute
and mature.
 
     Each of the Company and the Subsidiary Guarantors believes that it received
equivalent value at the time the indebtedness under the Old Notes was incurred.
In addition, neither the Company nor any Subsidiary Guarantor, after giving
effect to the consummation of the Notes Offering and Sea Mar Acquisition: (i)
believes that it was insolvent or rendered insolvent; (ii) believes that it was
engaged in a business or transaction for which its remaining assets constituted
unreasonably small capital or (iii) intended to incur, or believes that it would
incur, debts beyond its ability to pay as they mature. These beliefs are based
on the Company's analysis of internal cash flow projections and estimated values
of assets and liabilities of the Company and the Subsidiary Guarantors at the
time of the Notes Offering. There can be no assurance, however, that a court
passing on the issues would make the same determination.
 
ABSENCE OF PRIOR PUBLIC MARKET FOR NEW NOTES
 
     The New Notes will constitute a new class of securities with no established
trading market. Although the New Notes will generally be permitted to be resold
or otherwise transferred by nonaffiliates of the Company without compliance with
the registration requirements under the Securities Act, the Company does not
intend to apply for a listing of the New Notes on any securities exchange or to
arrange for the New Notes to be quoted on the NASDAQ National Market or other
quotation system. As a result there can be no assurance that an active trading
market for the New Notes will develop. If a market were to develop, the New
Notes could trade at prices that may be lower than the initial market values
thereof depending on many factors, including prevailing interest rates, the
Company's operating results and the market for similar securities.
 
RESTRICTIONS ON RESALE
 
     The Old Notes were offered and sold by the Company in a private offering
exempt from registration pursuant to the Securities Act and have been resold
pursuant to Rule 144A, Regulation S and certain other available exemptions under
the Securities Act. As a result, the Old Notes may not be reoffered or resold by
purchasers, except pursuant to an effective registration statement under the
Securities Act, or pursuant to an applicable exemption from such registration.
 
     Based on interpretations by the staff of the Commission, the Company
believes that each holder (other than (i) a broker-dealer who purchased Old
Notes directly from the Company for resale pursuant to Rule 144A of the
Securities Act or any other available exemption under the Securities Act, (ii)
an "affiliate" of the Company within the meaning of Rule 405 under the
Securities Act or (iii) a broker-dealer who acquired the Old Notes as a result
of market-making or other trading activities) who duly exchanges Old Notes for
New Notes in the Exchange Offer will receive notes that are freely transferable
under the Securities Act, provided, that such New Notes are acquired in the
ordinary course of such holder's business and that such holder is not
participating, and has no arrangement or understanding with any other person to
participate, in a distribution (within the meaning of the Securities Act) of the
New Notes. The Company has not, however, sought its own no-action letter from
the staff of the Commission regarding resales of the New Notes and there can be
no assurance that the staff of the Commission would make a similar determination
with respect to the resale of the New Notes. Any holder of Old Notes who is not
able to rely upon such staff interpretations must comply with the registration
and prospectus delivery requirements of the Securities Act in connection with
any sale of such Old Notes, unless such sale is made pursuant to an exemption
from such requirements. See "Prospectus Summary -- The Exchange Offer."
 
                                       16
<PAGE>   24
 
CONSEQUENCES OF FAILURE TO EXCHANGE
 
     To the extent that Old Notes are tendered and accepted for exchange
pursuant to the Exchange Offer, the trading market for Old Notes that remain
outstanding may be significantly more limited, which might adversely affect the
liquidity of the Old Notes not tendered for exchange. The extent of the market
therefor and the availability of price quotations would depend upon a number of
factors, including the number of holders of Old Notes remaining at such time and
the interest in maintaining a market in such Old Notes on the part of securities
firms. An issue of securities with a smaller outstanding market value available
for trading (the "float") may command a lower price than would a comparable
issue of securities with a greater float. As a result, the market price for Old
Notes that are not exchanged in the Exchange Offer may be affected adversely to
the extent that the amount of Old Notes exchanged pursuant to the Exchange Offer
reduces the float. The reduced float also may make the trading price of the Old
Notes that are not exchanged more volatile. In addition, holders of Old Notes
who do not exchange their Old Notes for New Notes pursuant to the Exchange Offer
will continue to be subject to restrictions on transfer of such Old Notes
contained in the legend thereon and, except in certain limited circumstances,
will no longer have any registration rights with respect to the Old Notes. In
general, the Old Notes may not be offered or sold unless registered under the
Securities Act, except pursuant to an exemption from, or in a transaction not
subject to, the Securities Act and applicable state securities laws. The Company
does not currently anticipate that it will register the Old Notes under the
Securities Act. See "The Exchange Offer -- Consequences of Failure to Exchange."

                               THE EXCHANGE OFFER
 
GENERAL
 
     The Company hereby offers, upon the terms and subject to the conditions set
forth in this Prospectus and in the accompanying Letter of Transmittal (which
together constitute the Exchange Offer), to exchange up to $150 million
aggregate principal amount of New Notes for a like aggregate principal amount of
Old Notes properly tendered on or prior to the Expiration Date and not withdrawn
as permitted pursuant to the procedures described below. The Exchange Offer is
being made with respect to any and all of the Old Notes. As of the date of this
Prospectus, $150 million aggregate principal amount of the Old Notes is
outstanding.
 
     The Company's obligation to accept Old Notes for exchange pursuant to the
Exchange Offer is subject to certain conditions set forth under "-- Certain
Conditions to the Exchange Offer" below. The Company currently expects that each
of the conditions will be satisfied and that no waivers will be necessary.
 
PURPOSE OF THE EXCHANGE OFFER
 
     The New Notes are being offered hereunder in order to satisfy certain
obligations of the Company and the Subsidiary Guarantors contained in the
Registration Rights Agreement dated March 31, 1998 (the "Registration Rights
Agreement"), among the Company, the Subsidiary Guarantors and SBC Warburg Dillon
Read Inc., Morgan Stanley & Co. Incorporated and Johnson Rice & Company L.L.C.
(the "Initial Purchasers"), with respect to the initial sale of the Old Notes.
The Old Notes were originally issued and sold on March 31, 1998, (the "Notes
Offering") in transactions that were not registered under the Securities Act in
reliance upon the exemption provided in Section 4(2) of the Securities Act. The
Initial Purchasers subsequently resold the Old Notes to "qualified institutional
buyers" in reliance upon Rule 144A under the Securities Act and pursuant to
offers and sales that occurred outside the United States within the meaning of
Regulation S under the Securities Act. Accordingly, the Old Notes may not be
reoffered, resold or otherwise transferred unless they are registered under the
Securities Act or unless an applicable exemption from the registration
requirements of the Securities Act is available. See "The Exchange
Offer -- Purpose of the Exchange Offer."
 
     In connection with the issuance and sale of the Old Notes, the Company
entered into the Registration Rights Agreement, which requires that, among other
things, the Company file with the SEC a registration statement relating to the
Exchange Offer not later than 60 days after the date of issuance of the Old
Notes, use its best efforts to cause the registration statement relating to the
Exchange Offer to become effective under the Securities Act not later than 120
days after the date of issuance of the Old Notes and cause the Exchange Offer to
be consummated not later than 45 business days after the date of the
effectiveness of the Registration Statement (or use its best efforts to cause to
become effective a shelf registration statement with respect to resales of the
Old Notes by the 60th calendar day after the date on which the Company becomes
obligated to file such shelf registration statement). A copy of the Registration
Rights Agreement has been filed as an exhibit to the Registration Statement.
 
     The Exchange Offer is being made by the Company to satisfy its obligations
with respect to the Registration Rights Agreement. The term "holder," with
respect to the Exchange Offer, means any person in whose name Old Notes are
registered on the note register of the Company or any other person who has
obtained a properly completed bond power from the registered holder, or any
person whose Old Notes are held of record by The Depository Trust Company. Other
than pursuant to the Registration Rights Agreement, the Company is not required
to file any registration statement to register any outstanding Old Notes.
Holders of Old Notes who do not tender their Old Notes or whose Old Notes are
tendered but not accepted would have to rely on exemptions to registration
requirements under the securities laws, including the Securities Act, if they
wish to sell their Old Notes.
 
     The Company is making the Exchange Offer in reliance on the position of the
staff of the SEC as set forth in certain interpretive letters addressed to third
parties in other transactions. However, the Company has not sought its own
interpretive letter and there can be no assurance that the staff would make a
similar determination with respect to the Exchange Offer as it has in such
interpretive letters to third parties. Based
                                       18
<PAGE>   26
 
on these interpretations by the staff, the Company believes that the New Notes
issued pursuant to the Exchange Offer in exchange for Old Notes may be offered
for resale, resold and otherwise transferred by a holder (other than any holder
who is a broker-dealer or an "affiliate" of the Company within the meaning of
Rule 405 of the Securities Act) without further compliance with the registration
and prospectus delivery requirements of the Securities Act, provided that such
New Notes are acquired in the ordinary course of such holder's business and that
such holder is not participating, and has no arrangement or understanding with
any person to participate, in a distribution (within the meaning of the
Securities Act) of such New Notes. See "-- Resale of New Notes." Each
broker-dealer that receives New Notes for its own account in exchange for Old
Notes, where such Old Notes were acquired by such broker dealer as a result of
market making activities or other trading activities, must acknowledge that it
will deliver a prospectus in connection with any resale of such New Notes. See
"Plan of Distribution."
 
     The Registration Rights Agreement provides that if (i) the Company is not
required to file the Exchange Offer Registration Statement because the Exchange
Offer is not permitted by applicable law or Commission policy or (ii) any holder
of Transfer Restricted Securities (as defined herein) notifies the Company
within 20 days after the commencement of the Exchange Offer that (a) it is
prohibited by law or Commission policy from participating in the Exchange Offer
or (b) it may not resell the New Notes acquired by it in the Exchange Offer to
the public without delivering a prospectus, and the Prospectus contained in the
Exchange Offer Registration Statement is not appropriate or available for such
resales or (c) it is a broker-dealer and holds Old Notes acquired directly from
the Company or an affiliate of the Company, the Company will file with the
Commission a shelf registration statement (the "Shelf Registration Statement")
to cover resales of the Notes by the holders thereof who satisfy certain
conditions relating to the provision of information in connection with the Shelf
Registration Statement. For purposes of the foregoing, "Transfer Restricted
Securities" means each Old Note or New Note until (i) the date on which such Old
Note has been exchanged by a person other than a broker-dealer for a New Note in
the Exchange Offer, (ii) following the exchange by a broker-dealer in the
Exchange Offer of an Old Note for a New Note, the date on which such New Note is
sold to a purchaser who receives from such broker-dealer on or prior to the date
of such sale a copy of the prospectus contained in the Registration Statement,
(iii) the date on which such Old Note has been effectively registered under the
Securities Act and disposed of in accordance with the Shelf Registration
Statement or (iv) the date on which such Old Note could be resold pursuant to
Rule 144 under the Securities Act.
 
     The Registration Rights Agreement provides that if (a) the Company fails to
file within 60 days of the date the Old Notes were issued, or cause to become
effective within 120 days of the date the Old Notes were issued, the
Registration Statement or (b) the Company is obligated to file the Shelf
Registration Statement and such Shelf Registration Statement is not filed within
60 days, or declared effective within 120 days, of the date on which the Company
became so obligated or (c) the Company fails to consummate the Exchange Offer
within 45 days of the Exchange Offer Effective Date or (d) the Shelf
Registration Statement or the Registration Statement is declared effective but
thereafter ceases to be effective or usable in connection with resales of
Transfer Restricted Securities during the periods specified in the Registration
Rights Agreement (each such event referred to in clauses (a) through (d) above a
"Registration Default"), interest ("Special Interest") will accrue on the
principal amount of the Old Notes and the New Notes (in addition to the stated
interest on the Old Notes and the New Notes) from and including the date on
which any such Registration Default shall occur to but excluding the date on
which any such Registration Defaults have been cured. Special Interest will
accrue at a rate of 0.25% per annum during the 90-day period immediately
following the occurrence of any Registration Default and shall increase by 0.25%
per annum at the end of each subsequent 90-day period, but in no event shall
such rate exceed 1.5% per annum.
 
TERMS OF THE EXCHANGE
 
     The Company hereby offers to exchange, subject to the conditions set forth
herein and in the Letter of Transmittal accompanying this Prospectus, $1,000 in
principal amount of New Notes for each $1,000 in principal amount of the Old
Notes. The terms of the New Notes are identical in all material respects to the
terms of the Old Notes for which they may be exchanged pursuant to this Exchange
Offer, except that the New Notes will generally be freely transferable by
holders thereof and will not be subject to any covenant
 
                                       19
<PAGE>   27
 
regarding registration under the Securities Act. The New Notes will evidence the
same indebtedness as the Old Notes and will be entitled to the benefits of the
Indenture. See "Description of Notes."
 
     The Exchange Offer is not conditioned upon any minimum aggregate principal
amount of Old Notes being tendered for exchange.
 
     The Company has not requested, and does not intend to request, an
interpretation by the staff of the SEC with respect to whether the New Notes
issued pursuant to the Exchange Offer in exchange for the Old Notes may be
offered for sale, resold or otherwise transferred by any holder without
compliance with the registration and prospectus delivery provisions of the
Securities Act. Instead, based on an interpretation by the staff of the SEC, set
forth in a series of no-action letters issued to third parties, the Company
believes that New Notes issued pursuant to the Exchange Offer in exchange for
Old Notes may be offered for sale, resold and otherwise transferred by any
holder of such New Notes (other than any such holder that is a broker-dealer or
is an "affiliate" of the Company within the meaning of Rule 405 under the
Securities Act) without compliance with the registration and prospectus delivery
provisions of the Securities Act, provided that such New Notes are acquired in
the ordinary course of such holder's business and such holder has no arrangement
or understanding with any person to participate in the distribution of such New
Notes and neither such holder nor any other such person is engaging in or
intends to engage in a distribution of such New Notes. Since the SEC has not
considered the Exchange Offer in the context of a no-action letter, there can be
no assurance that the staff of the SEC would make a similar determination with
respect to the Exchange Offer. Any holder who is an affiliate of the Company or
who tenders in the Exchange Offer for the purpose of participating in a
distribution of the New Notes may be deemed to have received restricted
securities and cannot rely on such interpretation by the staff of the SEC and
must comply with the registration and prospectus delivery requirements of the
Securities Act in connection with any resale transaction. Each holder, other
than a broker-dealer, must acknowledge that it is not engaged in, and does not
intend to engage in, a distribution of New Notes. Each broker-dealer that
receives New Notes for its own account in exchange for Old Notes, where such Old
Notes were acquired by such broker-dealer as a result of market-making
activities or other trading activities, must acknowledge that it will deliver a
prospectus in connection with any resale of such New Notes. See "Plan of
Distribution."
 
     Interest on the New Notes will accrue from the last Interest Payment Date
on which interest was paid on the Old Notes so surrendered, or if no interest
has been paid on such Old Notes, from April 1, 1998.
 
     Tendering holders of the Old Notes shall not be required to pay brokerage
commissions or fees or, subject to the instructions in the Letter of
Transmittal, transfer taxes with respect to the exchange of the Old Notes
pursuant to the Exchange Offer.
 
EXPIRATION DATE; EXTENSION; TERMINATION; AMENDMENT
 
     The Exchange Offer will expire at 5:00 p.m., New York City time, on
               , 1998, unless the Company, has extended the period of time for
which the Exchange Offer is open (such date, as it may be extended, is referred
to herein as the "Expiration Date"). The Expiration Date will be at least 20
business days after the commencement of the Exchange Offer in accordance with
Rule 14e-1(a) under the Exchange Act. The Company expressly reserves the right,
at any time or from time to time, in its sole discretion, to extend the period
of time during which the Exchange Offer is open, and thereby delay acceptance
for exchange of any Old Notes, by giving oral or written notice to the exchange
agent and by timely public announcement no later than 9:00 a.m. New York City
time, on the next business day after the previously scheduled Expiration Date.
During any such extension, all Old Notes previously tendered will remain subject
to the Exchange Offer unless properly withdrawn.
 
     The Company expressly reserves the right to (i) terminate or amend the
Exchange Offer and not to accept for exchange any Old Notes not theretofore
accepted for exchange upon the occurrence of any of the events specified below
under "-- Certain Conditions to the Exchange Offer" which have not been waived
by the Company and (ii) amend the terms of the Exchange Offer in any manner
which, in its good faith judgment, is advantageous to the holders of the Old
Notes, whether before or after any tender of the Old Notes. If any such
termination or amendment occurs, the Company will notify the Exchange Agent and
will
 
                                       20
<PAGE>   28
 
either issue a press release or give oral or written notice to the holders of
the Old Notes as promptly as practicable.
 
     For purposes of the Exchange Offer, a "business day" means any day other
than Saturday, Sunday or a date on which banking institutions are required or
authorized by New York State law to be closed, and consists of the time period
from 12:01 a.m. through 12:00 midnight, New York City time. Unless the Company
terminates the Exchange Offer prior to 5:00 p.m., New York City time, on the
Expiration Date, the Company will, subject to the conditions described under
"-- Certain Conditions to the Exchange Offer," exchange the New Notes for the
Old Notes on the Exchange Date.
 
PROCEDURES FOR TENDERING OLD NOTES
 
     The tender to the Company of Old Notes by a holder thereof as set forth
below and the acceptance thereof by the Company will constitute a binding
agreement between the tendering holder and the Company upon the terms and
subject to the conditions set forth in this Prospectus and in the accompanying
Letter of Transmittal.
 
     A holder of Old Notes may tender the same by (i) properly completing and
signing the Letter of Transmittal or a facsimile thereof (all references in this
Prospectus to the Letter of Transmittal shall be deemed to include a facsimile
thereof) and delivering the same, together with the certificate or certificates
representing the Old Notes being tendered and any required signature guarantees
and any other documents required by the Letter of Transmittal, to the Exchange
Agent at its address set forth below on or prior to the Expiration Date (or
complying with the procedure for book-entry transfer described below) or (ii)
complying with the guaranteed delivery procedures described below.
 
     Any beneficial owner whose Old Notes are registered in the name of a
broker, dealer, commercial bank, trust company or other nominee and who wishes
to tender should contact such registered holder promptly and instruct such
registered holder to tender on such beneficial owner's behalf. If such
beneficial owner wishes to tender on such beneficial owner's own behalf, such
beneficial owner must, prior to completing and executing the Letter of
Transmittal and delivering the Old Notes, either make appropriate arrangements
to register ownership of the Old Notes in such beneficial owner's name or obtain
a properly completed bond power from the registered holder. The transfer of
registered ownership may take considerable time.
 
     THE METHOD OF DELIVERY OF OLD NOTES, LETTERS OF TRANSMITTAL AND ALL OF THE
REQUIRED DOCUMENTS IS AT THE ELECTION AND RISK OF THE HOLDER. IF SUCH DELIVERY
IS BY MAIL, IT IS RECOMMENDED THAT REGISTERED MAIL PROPERLY INSURED, WITH RETURN
RECEIPT REQUESTED, BE USED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO
INSURE TIMELY DELIVERY. NO OLD NOTES OR LETTERS OF TRANSMITTAL SHOULD BE SENT TO
THE COMPANY.
 
     If tendered Old Notes are registered in the name of the signer of the
Letter of Transmittal and the New Notes to be issued in exchange therefor are to
be issued (and any untendered Old Notes are to be reissued) in the name of the
registered holder (which term, for the purposes described herein, shall include
any participant in The Depository Trust Company (the "Book-Entry Transfer
Facility") whose name appears on a security listing as the owner of Old Notes),
the signature of such signer need not be guaranteed. In any other case, the
tendered Old Notes must be endorsed or accompanied by written instruments of
transfer in form satisfactory to the Company and duly executed by the registered
holder, and the signature on the endorsement or instrument of transfer must be
guaranteed by a bank, broker, dealer, credit, union, savings association,
clearing agency or other institution (each an "Eligible Institution") that is a
member of a recognized signature guarantee medallion program within the meaning
of Rule 17Ad-L5 under the Exchange Act. If the New Notes and/or Old Notes not
exchanged are to be delivered to an address other than that of the registered
holder appearing on the note register for the Old Notes, the signature in the
Letter of Transmittal must be guaranteed by an Eligible Institution.
 
     The Exchange Agent will make a request within two business days after the
date of receipt of this Prospectus to establish accounts with respect to the Old
Notes at the Book-Entry Transfer Facility for the
 
                                       21
<PAGE>   29
 
purpose of facilitating the Exchange Offer, and subject to the establishment
thereof, any financial institution that is a participant in the Book-Entry
Transfer Facility's system may make book-entry delivery of Old Notes by causing
such Book-Entry Transfer Facility to transfer such Old Notes into the Exchange
Agent's account with respect to the Old Notes in accordance with the Book-Entry
Transfer Facility's procedures for such transfer. Although delivery of Old Notes
may be effected through book-entry transfer into the Exchange Agent's account at
the Book-Entry Transfer Facility, an appropriate Letter of Transmittal with any
required signature guarantee and all other required documents must in each case
be transmitted to and received or confirmed by the Exchange Agent at its address
set forth below on or prior to the Expiration Date, or, if the guaranteed
delivery procedures described below are complied with, within the time period
provided under such procedures.
 
     If a holder desires to tender Old Notes in the Exchange Offer and time will
not permit a Letter of Transmittal or Old Notes to reach the Exchange Agent
before the Expiration Date or the procedure for book-entry transfer cannot be
completed on a timely basis, a tender may be effected if the Exchange Agent has
received at its address set forth below on or prior to the Expiration Date, a
letter, telegram or facsimile transmission (receipt confirmed by telephone and
an original delivered by guaranteed overnight courier) from an Eligible
Institution setting forth the name and address of the tendering holder, the
names in which the Old Notes are registered and, if possible, the certificate
numbers of the Old Notes to be tendered, and stating that the tender is being
made thereby and guaranteeing that within three business days after the
Expiration Date, the Old Notes in proper form for transfer (or a confirmation of
book-entry transfer of such Old Notes into the Exchange Agent's account at the
Book-Entry Transfer Facility), will be delivered by such Eligible Institution
together with a properly completed and duly executed Letter of Transmittal (and
any other required documents). Unless Old Notes being tendered by the
above-described method are deposited with the Exchange Agent within the time
period set forth above (accompanied or preceded by a properly completed Letter
of Transmittal and any other required documents), the Company may, at its
option, reject the tender. Copies of the notice of guaranteed delivery ("Notice
of Guaranteed Delivery") which may be used by Eligible Institutions for the
purposes described in this paragraph are available from the Exchange Agent.
 
     A tender will be deemed to have been received as of the date when (i) the
tendering holder's properly completed and duly signed Letter of Transmittal
accompanied by the Old Notes (or a confirmation of book-entry transfer of such
Old Notes into the Exchange Agent's account at the Book-Entry Transfer Facility)
is received by the Exchange Agent, or (ii) a Notice of Guaranteed Delivery or
letter, telegram or facsimile transmission to similar effect (as provided above)
from an Eligible Institution is received by the Exchange Agent. Issuances of New
Notes in exchange for Old Notes tendered pursuant to a Notice of Guaranteed
Delivery or letter, telegram or facsimile transmission to similar effect (as
provided above) by an Eligible Institution will be made only against deposit of
the Letter of Transmittal (and any other required documents) and the tendered
Old Notes.
 
     All questions as to the validity, form, eligibility (including time of
receipt) and acceptance of Old Notes tendered for exchange will be determined by
the Company in its sole discretion, which determination shall be final and
binding on all parties. The Company reserves the absolute right to reject any
and all tenders of any particular Old Notes not properly tendered or not to
accept any particular Old Notes which acceptance might, in the judgment of the
Company or its counsel, be unlawful. The Company also reserves the absolute
right to waive any defects or irregularities or conditions of the Exchange Offer
as to any particular Old Notes either before or after the Expiration Date
(including the right to waive the ineligibility of any holder who seeks to
tender Old Notes in the Exchange Offer). The interpretation of the terms and
conditions of the Exchange Offer (including the Letter of Transmittal and the
instructions thereto) by the Company shall be final and binding on all parties.
Unless waived, any defects or irregularities in connection with tenders of Old
Notes for exchange must be cured within such reasonable period of time as the
Company shall determine. Neither the Company, the Exchange Agent nor any other
person shall be under any duty to give notification of any defect or
irregularity with respect to any tender of Old Notes for exchange, nor shall any
of them incur any liability for failure to give such notification.
 
                                       22
<PAGE>   30
 
     If the Letter of Transmittal is signed by a person or persons other than
the registered holder or holders of Old Notes, such Old Notes must be endorsed
or accompanied by appropriate powers of attorney, in either case signed exactly
as the name or names of the registered holder or holders appear on the Old
Notes.
 
     If the Letter of Transmittal or any Old Notes or powers of attorney are
signed by trustees, executors, administrators, guardians, attorneys-in-fact,
officers of corporations or others acting in a fiduciary or representative
capacity, such persons should so indicate when signing, and, unless waived by
the Company, proper evidence satisfactory to the Company of their authority to
so act must be submitted.
 
     By tendering, each holder will represent to the Company that, among other
things, the New Notes acquired pursuant to the Exchange Offer are being acquired
in the ordinary course of business of the person receiving such New Notes,
whether or not such person is the holder, that neither the holder nor any such
other person has an arrangement or understanding with any person to participate
in the distribution of such New Notes and that neither the holder nor any such
other person is an "affiliate," as defined under Rule 405 of the Securities Act,
of the Company, or if it is an affiliate, it will comply with the registration
and prospectus requirements of the Securities Act to the extent applicable.
 
     Each broker-dealer that receives New Notes for its own account in exchange
for Old Notes where such Old Notes were acquired by such broker-dealer as a
result of market-making activities or other trading activities (other than Old
Notes acquired directly from the Company) must acknowledge that it will deliver
a prospectus in connection with any resale of such New Notes. See "Plan of
Distribution."
 
TERMS AND CONDITIONS OF THE LETTER OF TRANSMITTAL
 
     The Letter of Transmittal contains, among others things, the following
terms and conditions, which are part of the Exchange Offer.
 
     The party tendering Old Notes for exchange (the "Transferor") exchanges,
assigns and transfers the Old Notes to the Company and irrevocably constitutes
and appoints the Exchange Agent as the Transferor's agent and attorney-in-fact
to cause the Old Notes to be assigned, transferred and exchanged. The Transferor
represents and warrants that it has full power and authority to tender,
exchange, assign and transfer the Old Notes and to acquire New Notes issuable
upon the exchange of such tendered Old Notes, and that, when the same are
accepted for exchange, the Company will acquire good and unencumbered title to
the tendered Old Notes, free and clear of all liens, restrictions, charges and
encumbrances and not subject to any adverse claim. The Transferor also warrants
that it will, upon request, execute and deliver any additional documents deemed
by the Exchange Agent or the Company to be necessary or desirable to complete
the exchange, assignment and transfer of tendered Old Notes or transfer
ownership of such Old Notes on the account books maintained by a Book-Entry
Transfer Facility. The Transferor further agrees that acceptance of any tendered
Old Notes by the Company and the issuance of New Notes in exchange therefor
shall constitute performance in full by the Company of certain of its
obligations under the Registration Rights Agreement. All authority conferred by
the Transferor will survive the death or incapacity of the Transferor and every
obligation of the Transferor shall be binding upon the heirs, legal
representatives, successors, assigns, executors and administrators of such
Transferor.
 
     The Transferor certifies that it is not an "affiliate" of the Company
within the meaning of Rule 405 under the Securities Act and that it is acquiring
the New Notes offered hereby in the ordinary course of such Transferor's
business and that such Transferor has no arrangement with any person to
participate in the distribution of such New Notes. Each holder, other than a
broker-dealer, must acknowledge that it is not engaged in, and does not intend
to engage in a distribution of New Notes. Each Transferor which is a broker-
dealer receiving New Notes for its own account must acknowledge that it will
deliver a prospectus in connection with any resale of such New Notes. By so
acknowledging and by delivering a prospectus, a broker-dealer will not be deemed
to admit that it is an "underwriter' within the meaning of the Securities Act.
This Prospectus, as it may be amended or supplemented from time to time, may be
used by a broker-dealer in connection with resales of New Notes received in
exchange for Old Notes where such Old Notes were acquired by such broker-dealer
as a result of market-making activities or other trading activities. The
 
                                       23
<PAGE>   31
 
Company will make copies of this Prospectus available to any broker-dealer for
use in connection with any such resale.
 
WITHDRAWAL RIGHTS
 
     Tenders of Old Notes may be withdrawn at any time prior to 5:00 p.m., New
York City time, on the Expiration Date.
 
     For a withdrawal to be effective, a written notice of withdrawal sent by
telegram, facsimile transmission (receipt confirmed by telephone) or letter must
be received by the Exchange Agent at the address set forth herein prior to the
Expiration Date. Any such notice of withdrawal must (i) specify the name of the
person having tendered the Old Notes to be withdrawn (the "Depositor"), (ii)
identify the Old Notes to be withdrawn (including the certificate number or
numbers and principal amount of such Old Notes), (iii) specify the principal
amount of Old Notes to be withdrawn, (iv) include a statement that such holder
is withdrawing his election to have such Old Notes exchanged, (v) be signed by
the holder in the same manner as the original signature on the Letter of
Transmittal by which such Old Notes were tendered or as otherwise described
above (including any required signature guarantees) or be accompanied by
documents of transfer sufficient to have the Trustee under the Indenture
register the transfer of such Old Notes into the name of the person withdrawing
the tender and (vi) specify the name in which any such Old Notes are to be
registered, if different from that of the Depositor. The Exchange Agent will
return the properly withdrawn Old Notes promptly following receipt of notice of
withdrawal. If Old Notes have been tendered pursuant to the procedure for
book-entry transfer, any notice of withdrawal must specify the name and number
of the account at the Book-Entry Transfer Facility to be credited with the
withdrawn Old Notes or otherwise comply with the Book-Entry Transfer Facility's
procedure. All questions as to the validity of notices of withdrawals, including
time of receipt, will be determined by the Company in its sole discretion and
such determination will be final and binding on all parties.
 
     Any Old Notes so withdrawn will be deemed not to have been validly tendered
for exchange for purposes of the Exchange Offer. Any Old Notes which have been
tendered for exchange but which are not exchanged for any reason will be
returned to the holder thereof without cost to such holder (or, in the case of
Old Notes tendered by book-entry transfer into the Exchange Agent's account at
the Book-Entry Transfer Facility pursuant to the book-entry transfer procedures
described above, such Old Notes will be credited to an account with such Book
Entry Transfer Facility specified by the holder) as soon as practicable after
withdrawal, rejection of tender or termination of the Exchange Offer. Properly
withdrawn Old Notes may be retendered by following one of the procedures
described under "-- Procedures for Tendering Old Notes" above at any time on or
prior to the Expiration Date.
 
ACCEPTANCE OF OLD NOTE FOR EXCHANGE; DELIVERY OF NEW NOTES
 
     Upon satisfaction or waiver of all of the conditions to the Exchange Offer,
the Company will accept, promptly on the Exchange Date, all Old Notes properly
tendered and will issue the New Notes promptly after such acceptance. See
"-- Certain Conditions to the Exchange Offer" below. For purposes of the
Exchange Offer, the Company shall be deemed to have accepted properly tendered
Old Notes for exchange when, as and if the Company has given oral or written
notice thereof to the Exchange Agent.
 
     For each Old Note accepted for exchange, the holder of such Old Note will
receive a New Note having a principal amount equal to that of the surrendered
Old Note.
 
     In all cases, issuance of New Notes for Old Notes that are accepted for
exchange pursuant to the Exchange Offer will be made only after timely receipt
by the Exchange Agent of certificates for such Old Notes or a timely book-entry
confirmation of such Old Notes into the Exchange Agent's account at the Book-
Entry Transfer Facility, a properly completed and duly executed Letter of
Transmittal and all other required documents. If any tendered Old Notes are not
accepted for any reason set forth in the terms and conditions of the Exchange
Offer or if Old Notes are submitted for a greater principal amount than the
holder desires to exchange, such unaccepted or non-exchanged Old Notes will be
returned without expense to the tendering holder thereof (or, in the case of Old
Notes tendered by book-entry transfer into the Exchange Agent's
                                       24
<PAGE>   32
 
account at the Book-Entry Transfer Facility pursuant to the book-entry transfer
procedures described above, such non-exchanged Old Notes will be credited to an
account maintained with such Book-Entry Transfer Facility) as promptly as
practicable after the Exchange Date.
 
CERTAIN CONDITIONS TO THE EXCHANGE OFFER
 
     Notwithstanding any other provision of the Exchange Offer, or any extension
of the Exchange Offer, the Company shall not be required to accept for exchange,
or to issue New Notes in exchange for, any Old Notes and may terminate or amend
the Exchange Offer (by oral or written notice to the Exchange Agent or by a
timely press release) if at any time before the acceptance of such Old Notes for
exchange or the exchange of the New Notes for such Old Notes, any of the
following conditions exist:
 
          (a) any action or proceeding is instituted or threatened in any court
     or by or before any governmental agency or regulatory authority or any
     injunction, order or decree is issued with respect to the Exchange Offer
     which, in the sole judgment of the Company, might materially impair the
     ability of the Company to proceed with the Exchange Offer or have a
     material adverse affect on the contemplated benefits of the Exchange Offer
     to the Company; or
 
          (b) any change (or any development involving a prospective change)
     shall have occurred or be threatened in the business, properties, assets,
     liabilities, financial condition, operations, results of operations or
     prospects of the Company that is or may be adverse to the Company, or the
     Company shall have become aware of facts that have or may have adverse
     significance with respect to the value of the Old Notes or the New Notes or
     that may materially impair the contemplated benefits of the Exchange Offer
     to the Company; or
 
          (c) any law, rule or regulation or applicable interpretations of the
     staff of the SEC is issued or promulgated which, in the good faith
     determination of the Company, do not permit the Company to effect the
     Exchange Offer; or
 
          (d) any governmental approval has not been obtained, which approval
     the Company, in its sole discretion, deems necessary for the consummation
     of the Exchange Offer; or
 
          (e) there shall have been proposed, adopted or enacted any law,
     statute, rule or regulation (or an amendment to any existing law statute,
     rule or regulation) which, in the sole judgement of the Company, might
     materially impair the ability of the Company to proceed with the Exchange
     Offer or have a material adverse effect on the contemplated benefits of the
     Exchange Offer to the Company; or
 
          (f) there shall occur a change in the current interpretation by the
     staff of the SEC which permits the New Notes issued pursuant to the
     Exchange Offer in exchange for Old Notes to be offered for resale, resold
     and otherwise transferred by holders thereof (other than any such holder
     that is a broker dealer or an "affiliate" of the Company within the meaning
     of Rule 405 under the Securities Act) without compliance with the
     registration and prospectus delivery provisions of the Securities Act
     provided that such New Notes are acquired in the ordinary course of such
     holders' business and such holders have no arrangement with any person to
     participate in the distribution of such New Notes; or
 
          (g) there shall have occurred (i) any general suspension of,
     shortening of hours for, or limitation on prices for, trading in securities
     on any national securities exchange or in the over-the-counter market
     (whether or not mandatory), (ii) any limitation by any governmental agency
     or authority which may adversely affect the ability of the Company to
     complete the transactions contemplated by the Exchange Offer, (iii) a
     declaration of a banking moratorium or any suspension of payments in
     respect of banks by Federal or state authorities in the United States
     (whether or not mandatory), (iv) a commencement of a war, armed hostilities
     or other international or national crisis directly or indirectly involving
     the United States, (v) any limitation (whether or not mandatory) by any
     governmental authority on, or other event having a reasonable likelihood of
     affecting, the extension of credit by banks or other leading institutions
     in the United States, or (vi) in the case of any of the foregoing existing
     at the time of the commencement of the Exchange Offer, a material
     acceleration or worsening thereof.
 
                                       25
<PAGE>   33
 
     The Company expressly reserves the right to terminate the Exchange Offer
and not accept for exchange any Old Notes upon the occurrence of any of the
foregoing conditions (which represent all of the material conditions to the
acceptance by the Company of properly tendered Old Notes). In addition, the
Company may amend the Exchange Offer at any time prior to the Expiration Date if
any of the conditions set forth above occur. Moreover, regardless of whether any
of such conditions has occurred, the Company may amend the Exchange Offer in any
manner which, in its good faith judgment, is advantageous to holders of the Old
Notes.
 
     The foregoing conditions are for the sole benefit of the Company and may be
asserted by the Company regardless of the circumstances giving rise to any such
condition or may be waived by the Company in whole or in part at any time and
from time to time in its sole discretion. The failure by the Company at any time
to exercise any of the foregoing rights shall not be deemed a waiver of any such
right and each such right shall be deemed an ongoing right which may be asserted
at any time and from time to time. If the Company waives or amends the foregoing
conditions, it will, if required by law, extend the Exchange Offer for a minimum
of five business days from the date that the Company first gives notice, by
public announcement or otherwise, of such waiver or amendment, if the Expiration
Date would otherwise occur within such five business-day period. Any
determination by the Company concerning the events described above will be final
and binding upon all parties.
 
     In addition, the Company will not accept for exchange any Old Notes
tendered, and no New Notes will be issued in exchange for any such Old Notes, if
at such time any stop order shall be threatened or in effect with respect to the
Registration Statement of which this Prospectus constitutes a part or the
qualification of the Indenture under the Trust Indenture Act of 1939, as
amended. In any such event the Company is required to use every reasonable
effort to obtain the withdrawal of any stop order at the earliest possible time.
 
     The Exchange Offer is not conditioned upon any minimum principal amount of
Old Notes being tendered for exchange.

     DELIVERY TO AN ADDRESS OTHER THAN AS SET FORTH IN THE LETTER OF
TRANSMITTAL, OR TRANSMISSIONS OF INSTRUCTIONS VIA A FACSIMILE OR TELEX NUMBER
OTHER THAN THE ONES SET FORTH IN THE LETTER OF TRANSMITTAL, WILL NOT CONSTITUTE
A VALID DELIVERY.
 
SOLICITATION OF TENDERS, FEES AND EXPENSES
 
     The Company has not retained any dealer-manager in connection with the
Exchange Offer and will not make any payments to brokers, dealers or others
soliciting acceptances of the Exchange Offer. The Company, however, will pay the
Exchange Agent reasonable and customary fees for its services and will reimburse
it for
                                       26
<PAGE>   34
 
its reasonable out-of-pocket expenses in connection therewith. The Company will
also pay brokerage houses and other custodians, nominees and fiduciaries the
reasonable out-of-pocket expenses incurred by them in forwarding copies of this
and other related documents to the beneficial owners of the Old Notes and in
handling or forwarding tenders for their customers.
 
     The estimated cash expenses to be incurred in connection with the Exchange
Offer will be paid by the Company and are estimated in the aggregate to be
approximately $100,000 which includes fees and expenses of the Exchange Agent,
Trustee, registration fees, accounting, legal, printing and related fees and
expenses.
 
     No person has been authorized to give any information or to make any
representations in connection with the Exchange Offer other than those contained
in this Prospectus. If given or made, such information or representations should
not be relied upon as having been authorized by the Company.
 
     Neither the delivery of this Prospectus nor any exchange made hereunder
shall, under any circumstances, create any implication that there has been no
change in the affairs of the Company since the respective dates as of which
information is given herein. The Exchange Offer is not being made to (nor will
tenders be accepted from or on behalf of) holders of Old Notes in any
jurisdiction in which the making of the Exchange Offer or the acceptance thereof
would not be in compliance with the laws of such jurisdiction. However, the
Company may, at its discretion, take such action as it may deem necessary to
make the Exchange Offer in any such jurisdiction and extend the Exchange Offer
to holders of Old Notes in such jurisdiction.
 
TRANSFER TAXES
 
     The Company will pay all transfer taxes, if any, applicable to the exchange
of Old Notes pursuant to the Exchange Offer. If, however, certificates
representing New Notes or Old Notes for principal amounts not tendered or
accepted for exchange are to be delivered to, or are to be issued in the name
of, any person other than the registered holder of the Old Notes tendered, or if
tendered Old Notes are registered in the name of any person other than the
person signing the Letter of Transmittal, or if a transfer tax is imposed for
any reason other than the exchange of Old Notes pursuant to the Exchange Offer,
then the amount of any such transfer taxes (whether imposed on the registered
holder or any other persons) will be payable by the tendering holder. If
satisfactory evidence of payment of such taxes or exemption therefrom is not
submitted with the Letter of Transmittal, the amount of such transfer taxes will
be billed directly to such tendering holder.
 
ACCOUNTING TREATMENT
 
     The New Notes will be recorded at the carrying value of the Old Notes as
reflected in the Company's accounting records on the Exchange Date. Accordingly,
no gain or loss for accounting purposes will be recognized by the Company upon
the exchange of New Notes for Old Notes. Expenses incurred in connection with
the issuance of the New Notes will be amortized over the term of the New Notes.
 
CONSEQUENCES OF FAILURE TO EXCHANGE
 
     Holders of Old Notes who do not tender their Old Notes for New Notes
pursuant to the Exchange Offer will continue to be subject to the restrictions
on transfer of such Old Notes as set forth in the legend thereon and, except in
certain limited circumstances, will no longer have any registration rights with
respect to the Old Notes. Old Notes not exchanged pursuant to the Exchange Offer
will continue to remain outstanding in accordance with their terms. In general,
the Old Notes may not be offered or sold unless registered under the Securities
Act, except pursuant to an exemption from, or in a transaction not subject to,
the Securities Act and applicable state securities laws. The Company does not
currently anticipate that it will register the Old Notes under the Securities
Act.
 
     Participation in the Exchange Offer is voluntary, and holders of Old Notes
should carefully consider whether to participate. Holders of Old Notes are urged
to consult their financial and tax advisors in making their own decision whether
or not to tender their Old Notes. See "Certain U.S. Federal Income Tax
Considerations."

     As a result of the making of, and upon acceptance for exchange of all
validly tendered Old Notes pursuant to the terms of, this Exchange Offer, the
Company will have fulfilled certain covenants contained in the Registration
Rights Agreement. Holders of Old Notes who do not tender their Old Notes in the
Exchange Offer will continue to hold such Old Notes and will be entitled to all
the rights and preferences and will be subject to the limitations applicable
thereto under the Indenture, except for any such rights under the Registration
Rights Agreement that by their terms terminate or cease to have further
effectiveness as a result of the making of this Exchange Offer. All untendered
Old Notes will continue to be subject to the restrictions on transfer set forth
in the legend thereon. To the extent that Old Notes are tendered and accepted in
the Exchange Offer, the trading market for untendered Old Notes could be
adversely affected.
 
     The Company may in the future seek to acquire, subject to the terms of the
Indenture, untendered Old Notes in open market or privately negotiated
transactions, through subsequent exchange offers or otherwise. The Company has
no present plan to acquire any Old Notes which are not tendered in the Exchange
Offer.
 
RESALE OF NEW NOTES
 
     The Company is making the Exchange Offer in reliance on the position of the
staff of the SEC as set forth in certain interpretive letters addressed to third
parties in other transactions. However, the Company has not sought its own
interpretive letter and there can be no assurance that the staff would make a
similar determination with respect to the Exchange Offer as it has in such
interpretative letters to third parties. Based on these interpretations by the
staff, the Company believes that the New Notes issued pursuant to the Exchange
Offer in exchange for Old Notes may be offered for resale, resold and otherwise
transferred by a holder (other than any holder who is a broker-dealer or an
"affiliate" of the Company within the meaning of rule 405 of the Securities Act)
without further compliance with the registration and prospectus delivery
requirements of the Securities Act, provided that such New Notes are acquired in
the ordinary course of such holder's business and that such holder is not
participating, and has no arrangement or understanding with any person to
participate, in a distribution (within the meaning of the Securities Act) of
such New Notes. However, any holder who is an "affiliate" of the Company or who
has an arrangement or understanding with respect to the distribution of the New
Notes to be acquired pursuant to the Exchange Offer, or any broker-dealer who
purchased Old Notes from the Company to resell pursuant to Rule 144A or any
other available exemption under the Securities Act (i) cannot rely on the
applicable interpretations of the staff and (ii) must comply with the
registration and prospectus delivery requirements of the Securities Act. A
broker-dealer who holds Old Notes that were acquired for its own account as a
result of market-making or other trading activities may be deemed to be an
"underwriter" within the meaning of the Securities Act and must, therefore,
deliver a prospectus meeting the requirements of the Securities Act in
connection with any resale of New Notes. Each such broker dealer that receives
New Notes for its own account in exchange for Old Notes, where such Old Notes
were acquired by such broker-dealer as a result of market-making activities or
other trading activities (other than Old Notes acquired directly from the
Company) must acknowledge in the Letter of Transmittal that it will deliver a
prospectus in connection with any resale of such New Notes. This Prospectus, as
it may be amended or supplemented from time to time, may be used by such
broker-dealers in connection with such resales. See "Plan of Distribution."
 
     In addition, to comply with the securities laws of certain jurisdictions,
if applicable, the New Notes may not be offered or sold unless they have been
registered or qualified for sale in such jurisdiction or an exemption from
registration or qualification is available and is complied with. The Company has
agreed, pursuant to the Registration Rights Agreement and subject to certain
specified limitations therein, to cooperate with the Holders of the New Notes in
connection with the registration and qualification (or exemption from such
registration or qualification) of the New Notes for offer or sale under the
securities or blue sky laws of such jurisdictions as any holder of the New Notes
reasonably requests in writing. Such registration or qualification may require
the imposition of restrictions or conditions (including suitability requirements
for offerees or purchasers) in connection with the offer or sale of any New
Notes.

                                USE OF PROCEEDS
 
     The Company will not receive any cash proceeds or incur any additional
indebtedness as a result of the issuance of the New Notes pursuant to the
Exchange Offer.
 
     The net proceeds to the Company from the offering of the Old Notes were
approximately $145.7 million, after deducting the Initial Purchasers' discount
and other expenses related to the Notes Offering. The Company used the net
proceeds of the Notes Offering as follows: (i) approximately $75.9 million to
consummate the Sea Mar Acquisition, (ii) $15.7 million to repay the debt of Sea
Mar, and (iii) approximately $54.1 million to reduce the outstanding balance
under the Credit Agreement.

                  SELECTED HISTORICAL AND PRO FORMA CONDENSED
                          CONSOLIDATED FINANCIAL DATA
 
     The following table sets forth certain historical and pro forma
consolidated financial data of the Company. The historical data have been
derived from the Company's audited consolidated financial statements as of and
for the five years ended December 31, 1997 and unaudited consolidated financial
statements for the three months ended March 31, 1998 and 1997. Fiscal year 1997
results include the results from A.A. Oilfield Services, Inc. ("A.A.") since its
November 1997 acquisition, Trey Services, Inc. ("Trey") since its October 1997
acquisition and DA&S Oil Well Servicing, Incorporated ("DA&S") since its June
1997 acquisition. Fiscal year 1996 results include the results from Antah
Drilling Sdn. Bhd. ("Antah Drilling"), now Pool International Malaysia Sdn. Bdn.
("Pool Malaysia"), since the acquisition of the interest of the Company's former
partner in October 1996 and Pool International Argentina S.A. ("PIASA") since
the Company's August 1996 purchase of a 51% interest. Fiscal year 1995 results
include the results of Golden Pacific Corp. ("GPC") since its June 1995
acquisition. Fiscal year 1994 results include the results of Pool Arctic Alaska
since the acquisition of the interest of the Company's former partner in
September 1994. All of these acquisitions were accounted for under the purchase
method of accounting. See Note 3 of the Company's Notes to Consolidated
Financial Statements appearing elsewhere in this Prospectus. The unaudited
selected pro forma income statement data for the year ended December 31, 1997
and the three months ended March 31, 1998 gives effect to the completion of the
Sea Mar Acquisition and the Notes Offering and the application of the net
proceeds therefrom as if the Sea Mar Acquisition and the Notes Offering had been
consummated on January 1, 1997 and January 1, 1998, respectively. Neither the
summary historical financial data nor the summary pro forma financial data are
necessarily indicative of either the future results of operations or the results
of operations that would have occurred if those events had been consummated on
the indicated dates. The following financial data should be read in conjunction
with and are qualified by reference to, the Unaudited Pro Forma Condensed
Consolidated Financial Data of the Company and the notes thereto, "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and
the Consolidated Financial Statements and notes thereto and other financial
information all of which are included elsewhere in this Prospectus. The results
of the three months ended March 31, 1998 are not necessarily indicative of the
results expected for the full year.

(1) See Note 7 of Notes to Consolidated Financial Statements for a discussion of
    the $23.6 million pretax ($15.3 million, or $1.13 per share, after-tax)
    provision for leasehold impairment.
 
(2) EBITDA (earnings before interest, taxes, depreciation and amortization and
    minority interest) is not a measure of financial performance under generally
    accepted accounting standards, but is presented here to provide additional
    information about the Company's operations. EBITDA should not be considered
    as an alternative to net income as an indicator of the Company's operating
    performance or as an alternative to cash flows as a better measure of
    liquidity. EBITDA presented above may not be comparable to similarly titled
    measures of other companies. Excluding the $23.6 million non-cash pretax
    provision for leasehold impairment, the 1994 EBITDA would be $16.5 million
    (see Note 7 of Notes to Consolidated Financial Statements).
 
(3) Excluding acquisitions of businesses.
 
(4) The ratio of earnings to fixed charges has been computed by dividing
    earnings available for fixed charges (earnings before income taxes plus
    fixed charges less capitalized interest) by fixed charges (interest expense
    plus capitalized interest plus the portion of operating lease rental expense
    that represents the interest factor which is deemed to be one-third of
    rentals). In the year ended December 31, 1994, earnings (following a
    significant one-time non-cash charge for leasehold impairment) were
    inadequate to cover fixed charges by $3.3 million.
 
(5) Cash interest expense represents total interest expense ($3,927 for the pro
    forma quarter ended March 31, 1998 and $16,437 for the pro forma year ended
    December 31, 1997) less amortization of deferred financing costs and other
    non-cash interest charges ($359 for the pro forma quarter ended March 31,
    1998 and $1,980 for the pro forma year ended December 31, 1997).

           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 statements of consolidated operations for the three months ended March
31, 1998 and 1997 and for the year ended December 31, 1997 were prepared
assuming the Sea Mar Acquisition had occurred at the beginning of the periods
presented. The unaudited pro forma condensed statements of consolidated
operations are based upon (i) the historical statements of consolidated
operations of the Company for the periods indicated and (ii) the historical
consolidated statements of operations of Sea Mar for the periods indicated. The
Unaudited Pro Forma Consolidated Financial Data and the Notes thereto should be
read in conjunction with "Use of Proceeds," "Management's Discussion and
Analysis of Financial Condition and Results of Operations" and the historical
financial statements of the Company and Sea Mar, including notes thereto
included elsewhere herein.
 
     The pro forma adjustments are derived from available information and are
based upon certain assumptions and estimates described in the Notes to the
Unaudited Pro Forma Condensed Financial Data. The purchase accounting
adjustments, including the allocation of the purchase price to the assets
acquired and liabilities assumed based on their respective fair values, are
preliminary. Accordingly, the purchase accounting adjustments reflected in the
pro forma information are also 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 condensed statements of consolidated operations do not purport to
represent what the Company's results of operations actually would have been had
such transaction occurred on the dates indicated or to project the Company's
results of operations for any future date or period. Furthermore, the unaudited
pro forma condensed statements of consolidated operations 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 (as defined in the Stock Purchase Agreement for the Sea Mar Acquisition)
targets for fiscal years ending December 31, 1998 and 1999. See Note (g) to the
Unaudited Pro Forma Condensed Financial Data.

    would eliminate the gain for the assets sold during the three months ended
    March 31, 1998.
 
 (c) Reflects estimated increase in expense resulting from the issuance of $150
     million Notes at an interest rate of 8 5/8% and amortization of the related
     debt issuance costs over ten years, offset by a decrease in interest
     expense from the repayment of the existing debt of Sea Mar concurrent with
     the consummation of the Sea Mar Acquisition ($15.7 million outstanding at
     March 31, 1998, $17.1 million outstanding at December 31, 1997 and $19.3
     million outstanding at March 31, 1997, which bore interest at a floating
     rate which was 7.66% at March 31, 1998 and December 31, 1997 and 7.44% at
     March 31, 1997 and had a maturity date of December 2001) and repayments on
     the Credit Agreement ($70.8 million at March 31, 1998, $51.8 million at
     December 31, 1997 and no amount was outstanding at March 31, 1997).
 
(d) Reflects estimated income taxes for Sea Mar and the pro forma adjustments,
    using a combined federal and state rate of 36.8%.
 
 (e) Estimated increase in weighted average shares outstanding due to issuance
     of 1,538,462 shares of the Company's common stock in connection with the
     Sea Mar Acquisition.
 
 (f) 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 Sea Mar 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 Sea Mar Acquisition).
 
 (g) Total estimated purchase price for the Sea Mar Acquisition does not include
     any of the additional maximum $20 million cash consideration that is
     contingent upon Sea Mar exceeding 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 Sea Mar Acquisition as shown
     in note (a) would increase $0.2 million per year for each $5.0 million of
     additional purchase consideration.

                  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                         CONDITION AND RESULTS OF OPERATIONS
 
     The following discussion and analysis should be read in conjunction with
the consolidated financial statements and the notes thereto included elsewhere
in this Prospectus.
 
RESULTS OF OPERATIONS
 
     The Company is a leading worldwide provider of well-servicing, workover and
drilling rig services and related transportation services for both land and
offshore markets to a diverse group of multi-national, foreign national and
independent oil and natural gas producers. From 1993 to 1997, the Company's
revenues increased from $240.5 million to $451.9 million, representing a
compound annual growth rate ("CAGR") of 17.1%. During the same period, the
Company's EBITDA increased from $24.4 million to $71.6 million, representing a
CAGR of 30.9%. The Company believes its growth in revenues and EBITDA was the
result of implementing its business strategies and capitalizing on its
competitive strengths as well as improved market conditions. The Company
believes its competitive strengths include: (i) availability and condition of
equipment to meet both special and general customer needs; (ii) availability of
trained personnel possessing the required specialized skills; (iii) the overall
quality of service and safety record; (iv) the ability to offer support vessel
services in the Gulf of Mexico; and (v) domestically the ability to offer
ancillary services such as fluid hauling, fluid storage tank rental and salt
water disposal.
 
     Over the last several years, there has been significant industry
consolidation activity in the Company's principal service lines of business. In
addition to opportunities for achieving cost savings, consolidation is being
driven by the expanding needs of customers for a broader range of services,
equipment and related technical skills. The Company has been an active
participant in this industry consolidation and, since the beginning of fiscal
year 1995, has completed four domestic land business acquisitions for total
consideration of approximately $64.7 million, acquired an offshore support
vessel company for approximately $76 million in cash and 1.5 million shares of
the Company's common stock, acquired the 51% interest that it did not already
own in Antah Drilling for $9.0 million and acquired a 51% interest in PIASA for
$8.7 million. These acquisitions, together with rig and equipment purchases and
rig enhancements and upgrades during this period (at an aggregate cost of
approximately $45.3 million), were designed to increase the Company's market
presence, increase the Company's geographic diversity (both domestically and
internationally), expand the range of services the Company provides to its
customers and provide opportunities for consolidation cost savings. For a
further description of the Company's acquisitions, see Note 3 of Notes to
Consolidated Financial Statements and Note 5 of Notes to Interim Condensed
Consolidated Financial Statements appearing elsewhere in this Prospectus.
 
Notes Offering
 
     On March 31, 1998, the Company completed a private placement of 8 5/8%
senior subordinated notes due 2008 in the aggregate principal amount of $150
million. The net proceeds from the sale of the Notes were used to fund the cash
portion of the purchase price for the Sea Mar Acquisition, to repay the existing
debt of Sea Mar and to reduce the outstanding balance under the Credit
Agreement. The Notes are general unsecured obligations of the Company
subordinated in right of payment to all existing and future senior indebtedness
of the Company and are unconditionally guaranteed, jointly and severally, by
each of the Subsidiary Guarantors. The Notes contain certain covenants that,
among other things, limit the ability of the Company and its Subsidiary
Guarantors to incur additional indebtedness, issue capital stock of Subsidiary
Guarantors, pay dividends or make other restricted payments, incur liens, enter
into certain transactions with affiliates, enter into certain mergers or
consolidations or sell all or substantially all of the assets of the Company and
its subsidiaries.
 
Acquisitions
 
     Sea Mar, Inc.  On March 31, 1998, the Company acquired all of the
outstanding capital stock of Sea Mar, a privately owned Louisiana-based offshore
vessel company with operations primarily in the Gulf of
 
                                       38
<PAGE>   46
 
Mexico, for approximately $75.9 million in cash (including an estimated $14.7
million in post-closing purchase price adjustments) and 1,538,462 shares of the
Company's common stock. In addition, the Company agreed to pay additional cash
consideration contingent upon Sea Mar exceeding certain financial targets for
the fiscal years ending December 31, 1998 and 1999, up to a maximum $10 million
in each year. See "Description of Other Indebtedness."
 
     As a result of the Sea Mar Acquisition, the Company now operates a
diversified fleet of 23 offshore support vessels in the Gulf of Mexico. In
addition, Sea Mar has a contract with a marine shipbuilder for the construction
of ten offshore support vessels at an estimated aggregate cost of $77.6 million,
net of deposits. These new vessels are scheduled to be delivered between late
1998 and early 2000. The Company anticipates that these expenditures will be
financed by internally generated funds and borrowings under the Credit Agreement
as needed.
 
     A.A. Oilfield Service, Inc. ("A.A.")  In November 1997, the Company
acquired A.A. for $4.1 million in cash. This acquisition included 18 oilfield
trucks, one salt water disposal well and related equipment based in Hobbs, New
Mexico. See "Description of Other Indebtedness."
 
     Trey Services, Inc. ("Trey")  In October 1997, the Company acquired all of
the outstanding capital stock of Trey and certain associated operating assets
for $31.3 million in cash. Prior to the acquisition, Trey, through its
wholly-owned subsidiary, R&H Well Service, Inc. ("R&H"), operated a fleet of
approximately 67 land well-servicing rigs, 104 oilfield trucks, 430 fluid
storage tanks and five brine and disposal wells in the Permian Basin of West
Texas. See "Description of Other Indebtedness."
 
     D A & S Oil Well Servicing, Incorporated. ("DA&S")  In June 1997, the
Company acquired all the outstanding capital stock of DA&S for $10.5 million.
Prior to the acquisition, DA&S operated a fleet of 37 land well-servicing rigs
from yards in Hobbs and Eunice, New Mexico and Andrews, Texas. See "Description
of Other Indebtedness."
 
     Antah Drilling Sdn. Bhd. ("Antah Drilling")  In October 1996, the Company
acquired the 51% beneficial ownership interest that it did not already own in
Antah Drilling (now Pool Malaysia). The purchase price and the repayment of
certain indebtedness that Antah Drilling owed to the Company's former partner in
that venture totaled $9.0 million. Pool Malaysia's assets include Rig 489, a
2,000 horsepower offshore platform drilling rig, which commenced a three-year
contract in Australia in August 1996, and an offshore platform workover rig
currently operating under a contract in Malaysia. See "Description of Other
Indebtedness."
 
     Pool International Argentina S.A. ("PIASA")  In August 1996, the Company
acquired for approximately $8.7 million in cash a 51% interest in PIASA. PIASA's
nine land drilling rigs and 11 land workover rigs operate in the Mendoza and
Neuquen basins of Argentina. See Note 1 of Notes to Consolidated Financial
Statements and Note 2 of Notes to Interim Condensed Consolidated Financial
Statements.
 
     Western Oil Well Service Co. ("Western Oil")  In June 1996, the Company
purchased the operating assets (including approximately 23 land well-servicing
rigs) of Western Oil for approximately $4.0 million in cash.
 
     Golden Pacific Corp. ("GPC")  In June 1995, the Company acquired all of the
outstanding capital stock of GPC. GPC's assets included a fleet of approximately
155 land well-servicing rigs and related equipment in California. See
"Description of Other Indebtedness."
 
Quarter Ended March 31, 1998 Compared to Quarter Ended March 31, 1997
 
     The Company generated net income of $7.5 million in the first quarter of
1998, compared with $3.8 million in the first quarter of 1997, despite the fact
that the average price of crude oil was approximately 30% lower in the first
quarter of 1998 than in the first quarter of 1997, and average domestic natural
gas prices decreased approximately 16% comparing the same periods. Results from
the Company's domestic operations improved primarily due to (i) higher land
drilling activity in Alaska, including the operation of Rig 8, a recently
upgraded drilling rig which commenced a five-year contract in February 1998,
(ii) inclusion of results from the land well-servicing rigs acquired in the
October 1997 Trey acquisition and in the June 1997 DA&S acquisition (see
"-- Acquisitions"), and (iii) increased activity and rates for the Company's
jackup workover rigs and platform drilling rigs in the Gulf of Mexico, including
newly constructed Rig 16 which was placed in service in February 1998. Rig hours
for the Company's domestic onshore operation were 14% higher
 
                                       39
<PAGE>   47
 
in the first quarter of 1998 than in the corresponding quarter of 1997. The
Company's offshore rig fleet in the Gulf of Mexico experienced rig utilization
of 59% in the first quarter of 1998, compared to 65% in the comparable period of
1997, but average rig rates were 26% higher in the 1998 period. Results from the
Company's international operations improved due to increased land drilling rig
activity in Ecuador, Pakistan and Guatemala.
 
     Revenues.  Revenues were $117.7 million in the first quarter of 1998, a 20%
increase over revenues of $98.4 million in the first quarter of 1997. This
increase was attributable to (i) the inclusion of revenues from the 67 land
well-servicing rigs acquired in the October 1997 Trey acquisition and the 37
land well-servicing rigs acquired in the June 1997 DA&S acquisition (see
"-- Acquisitions"), (ii) higher land drilling activity in Alaska, including
operation of Rig 8, (iii) increased activity and rates for the Company's jackup
workover rigs and platform drilling rigs in the Gulf of Mexico, including Rig
16, and (iv) increased land drilling activity in Ecuador, Guatemala and
Pakistan. These revenue increases were offset partly by lower revenues from
operations in Oman due to the transfer of a land drilling rig to Saudi Arabia
where the rig is being leased to Pool Arabia, Ltd., the Company's Saudi Arabia
affiliate, and reduced platform workover rig activity in the Gulf of Mexico. In
addition, the Company's revenues in the first quarter of 1998 did not include
revenues related to PIASA, the Company's Argentina affiliate, as a result of
changing its accounting for its 51% investment in PIASA to the equity method due
to the adoption of EITF 96-16, compared to the inclusion of $3.6 million of
revenues for PIASA in the first quarter of 1997 (see Note 2 to the Interim
Condensed Consolidated Financial Statements and "-- Earnings Attributable to
Unconsolidated Affiliates"). Domestic onshore well-servicing and production
services revenues increased $14.6 million or 25% in the first quarter of 1998
from the corresponding quarter of 1997, chiefly as a result of the inclusion of
results from rigs acquired from the Trey and DA&S acquisitions. Domestic onshore
rig utilization was 54% in the first quarter of 1998, compared to 55% in the
first quarter of 1997. Domestic onshore well-servicing rig hours increased from
approximately 291,000 in the first quarter of 1997 to approximately 330,000 in
the first quarter of 1998. Gulf of Mexico offshore workover and drilling
revenues increased $2.1 million or 13%, international operations revenues
decreased $2.2 million or 13%, (however, excluding the $3.6 million of revenues
from PIASA in the first quarter of 1997, international operations revenues
increased $1.5 million or 12%), and Alaska operations revenues increased $4.8
million or 78%, compared to the first quarter of 1997.
 
     Earning Attributable to Unconsolidated Affiliates.  The loss attributable
to unconsolidated affiliates was $0.1 million in the first quarter of 1998,
compared to earnings of $1.0 million in the first quarter of 1997. This decrease
was due to a $0.9 million loss attributable to PIASA in the first quarter of
1998. In August 1996, the Company acquired a 51% interest in PIASA, a newly
formed Argentina corporation. Prior to 1998, for financial reporting purposes,
100% of the assets, liabilities, results of operations and cash flows of PIASA
were consolidated with those of the Company. The minority shareholder's interest
in PIASA and the earnings or losses therefrom were reflected as "minority
interest" in the Company's financial statements. As a result of the adoption of
EITF 96-16, the Company concluded that PIASA no longer qualifies for full
consolidation and beginning January 1, 1998 is accounting for PIASA under the
equity method (see Note 2 to the Interim Condensed Consolidated Financial
Statements).
 
     Earnings attributable to Pool Arabia, Ltd. were $0.8 million in the first
quarter of 1998, a $0.2 million decrease from the comparable period of 1997 due
to a non-recurring income item in the first quarter of 1997.
 
     Costs and Expenses.  The Company's costs and expenses were $104.0 million
in the first quarter of 1998, a 12% increase compared to costs and expenses of
$93.2 million in the corresponding quarter of 1997; however, operating expenses
declined to 71% of revenues in the first quarter of 1998 from 76% of revenues in
the first quarter of 1997. The increase in costs and expenses was primarily due
to the inclusion of costs and expenses related to operating the land
well-servicing rigs acquired in the acquisition of Trey in October 1997 and DA&S
in June 1997 and increased land drilling activity in Alaska. The increase was
partly offset by decreased costs and expenses in Oman due to the transfer of a
land drilling rig to Saudi Arabia where the rig is being leased to Pool Arabia,
Ltd. In addition, the Company's costs and expenses in the first quarter of 1997
included $4.0 million of costs and expenses related to PIASA (see "-- Earnings
Attributable to Unconsolidated Affiliates").
 
                                       40
<PAGE>   48
 
     Other Income -- Net.  Other income-net was $0.2 million lower in the first
quarter of 1998 than in the corresponding quarter of 1997, primarily due to
lower gains on dispositions of equipment.
 
     Interest Expense.  Interest expense was $1.0 million higher in the first
quarter of 1998 than in the corresponding quarter of 1997, primarily due to
interest expense under the Credit Agreement and the $10.1 million in long-term
notes issued in connection with the DA&S acquisition in June 1997, partially
offset by a reduction in interest expense due to certain term loans being paid
off in October 1997 with borrowings under the Credit Agreement and a reduction
in the outstanding principal amount of certain 10% notes issued in connection
with the 1995 purchase of Golden Pacific Corp.
 
     Income Taxes.  The Company recorded income tax expense of $4.8 million
(which included $2.3 million of deferred taxes) on income before income taxes of
$12.2 million in the first quarter of 1998, compared to income tax expense of
$2.3 million (which included $2.0 million of deferred taxes) on income before
income taxes and minority interest of $6.0 million in the first quarter of 1997.
The increase in income tax expense in the first quarter of 1998 compared to the
first quarter of 1997 was primarily due to an increase in pre-tax income in the
first quarter of 1998, as a result of the factors described above. The Company's
interim period tax expense is determined by utilizing the aggregate of estimated
annual effective tax rates for each of the Company's domestic and foreign
locations.
 
1997 Compared To 1996
 
     The Company generated net income of $26.7 million in 1997, compared with
$9.6 million in 1996, despite the fact that the average price of crude oil was
approximately 7% lower in 1997 than in 1996 and average domestic natural gas
prices decreased approximately 2% comparing the same periods. Results from the
Company's domestic operations improved primarily due to (i) increased activity
and rates for the jack-up and platform rigs in the Gulf of Mexico, including the
full-year effect of operating Rig 18, a previously idle platform drilling rig
which was refurbished and placed in service in the Gulf of Mexico in
mid-September 1996, (ii) inclusion of results from the land well-servicing rigs
acquired from Western Oil in June 1996, from the DA&S acquisition in June 1997
and from the Trey acquisition in October 1997 (see "-- Acquisitions"), (iii)
increased land rig activity and rates in California and the Austin Chalk and
lower Gulf coast areas of Texas, and (iv) increased production services activity
and rates in Texas. The Company's domestic onshore operation rig hours were 13%
higher for 1997 than in 1996. The Company's offshore operation in the Gulf of
Mexico experienced rig utilization of 76% in 1997, compared to 71% in 1996; and
average rig rates were 35% higher in the 1997 period. Results from the Company's
international operations increased primarily due to the full-year effect of
operating Rig 489 (an offshore platform drilling rig owned by Pool Malaysia that
was newly constructed in 1996 and commenced a three-year contract in Australia
in August 1996) and higher rig activity in Oman and Saudi Arabia.
 
     Revenues.  Revenues were $451.9 million in 1997, a 30% increase over
revenues of $348.6 million in 1996. This increase was attributable to (i)
increased activity and rates for the Company's jack-up and platform rigs in the
Gulf of Mexico, including the full-year effect of operating Rig 18, (ii) the
inclusion of revenues from the 23 land well-servicing rigs purchased from
Western Oil in June 1996, the 37 land well-servicing rigs acquired in the June
1997 DA&S acquisition and the 67 land well-servicing rigs acquired in the
October 1997 Trey acquisition (see "-- Acquisitions"), (iii) higher domestic
land well-servicing activity and rates in California and the Austin Chalk and
lower Gulf coast areas of Texas, (iv) the inclusion of revenues from the two
offshore platform rigs owned by Pool Malaysia (previously Antah Drilling), the
results of which were included in earnings attributable to unconsolidated
affiliates in the first nine months of 1996 (see "-- Acquisitions -- Antah
Drilling Sdn. Bhd."), (v) the full-year effect of revenues from the Argentina
rigs owned by PIASA (see "-- Acquisitions -- Pool International Argentina
S.A."), (vi) higher production services activity and rates in Texas, and (vii)
higher rig activity in Oman and Guatemala during 1997. These revenue increases
were offset partly by lower revenues from operations in Ecuador, Pakistan and
Tunisia, where land rig activity declined.
 
     Domestic onshore well-servicing and production services revenues increased
$47.7 million or 22% in 1997 from 1996, chiefly as a result of the inclusion of
results from rigs acquired from Western Oil and the DA&S
 
                                       41
<PAGE>   49
 
and Trey acquisitions. Domestic onshore rig utilization was 56% in 1997,
compared to 52% in 1996. Domestic onshore well-servicing rig hours increased
from approximately 1,119,000 in 1996 to approximately 1,259,000 in 1997. Gulf of
Mexico offshore workover and drilling revenues increased $22.4 million or 38%,
international operations revenues increased $31.1 million or 68%, and Alaska
operations revenues increased $2.2 million or 9%, compared to 1996.
 
     Earnings Attributable to Unconsolidated Affiliates.  Earnings attributable
to unconsolidated affiliates were $3.1 million in 1997, compared to $2.2 million
in 1996. Earnings attributable to Pool Arabia, Ltd., the Company's Saudi Arabia
affiliate, increased $1.4 million from 1996 to $3.1 million in 1997 partly as a
result of higher rig utilization during 1997 and a day rate increase for one of
the drilling rigs in 1997. Earnings from Antah Drilling (now Pool Malaysia)
ceased to be included in earnings attributable to unconsolidated affiliates
immediately following the Company's purchase of its partner's interest in
October 1996.
 
     Costs and Expenses.  The Company's costs and expenses were $413.0 million
in 1997, a 24% increase compared to costs and expenses of $333.0 million in
1996; however, as a percentage of revenues, operating expenses declined to 74%
of revenues in 1997 from 77% of revenues in 1996. The increase in costs and
expenses was primarily due to the inclusion of costs and expenses related to (i)
increased domestic onshore rig and production services activity, including costs
and expenses of operating the land well-servicing rigs acquired from Western Oil
in June 1996, and in the acquisitions of DA&S in June 1997 and Trey in October
1997, (ii) the operation of Rig 18 for a full year and increased jack-up and
platform rig activity in the Gulf of Mexico, (iii) a full year of operations by
PIASA in Argentina, (iv) the inclusion, after the Company's acquisition of its
partner's interest in Antah Drilling (now Pool Malaysia) in October 1996, of
costs and expenses associated with the operation of two offshore platform rigs
owned by Pool Malaysia, and (v) higher rig activity in Oman and Guatemala. The
increase was partly offset by decreased costs and expenses in Ecuador, Pakistan
and Tunisia due to lower land rig activity in those operations during 1997.
 
     Other Income -- Net.  Other income-net was $2.5 million higher in 1997 than
in 1996 primarily due to higher gains on dispositions of equipment, including a
$0.7 million pre-tax gain on the sale of an obsolete offshore rig which had been
idle for several years and $1.9 million in pre-tax gains from insurance
settlements in 1997.
 
     Interest Expense.  Interest expense was $1.5 million higher in 1997 than in
1996 primarily due to interest expense on borrowings under the Credit Agreement,
the term loans assumed in the October 1996 Antah Drilling acquisition and the
$10.1 million in long-term notes issued in connection with the DA&S acquisition
in June 1997, partially offset by a reduction in interest expense due to the
scheduled principal payments made on the Company's other debt and a reduction in
the outstanding principal amount of certain 10% notes issued in connection with
the 1995 purchase of GPC. See Note 6 of Notes to Consolidated Financial
Statements.
 
     Income Taxes.  The Company recorded income tax expense of $15.7 million
(which included $10.7 million of deferred taxes) on income before income taxes
and minority interest of $42.3 million in 1997, compared to income tax expense
of $7.5 million on income before income taxes and minority interest of $17.1
million in 1996. The increase in income tax expense in 1997 compared to 1996 was
primarily due to an increase in pre-tax income in 1997, as a result of the
factors described above. See Note 5 of Notes to Consolidated Financial
Statements for the reconciliation between income taxes computed at the U.S.
federal statutory rate and the Company's income taxes for financial reporting
purposes.
 
1996 Compared To 1995
 
     The Company generated net income of $9.6 million in 1996, compared with
$3.1 million in 1995. The 1995 net income included a $0.4 million after-tax
charge for costs related to the GPC acquisition. The average price of crude oil
was approximately 20% higher in 1996 than in 1995, and average natural gas
prices increased approximately 64%, comparing the same periods. Results from the
Company's domestic operations improved primarily due to the higher activity and
increased rates for the Company's jackup rigs in the Gulf of Mexico and the
inclusion in 1996 of a full year's results from rigs and equipment acquired in
the June 1995 GPC acquisition. The Company's domestic onshore operation reported
rig hours 12% higher for 1996 than 1995, primarily due to the inclusion of rigs
acquired in the GPC acquisition. The Company's offshore operation in
                                       42
<PAGE>   50
 
the Gulf of Mexico experienced rig utilization of 71% in 1996, compared to 65%
in 1995; average rig rates were 29% higher in the 1996 period. Results from the
Company's international operations increased primarily due to higher land
drilling activity in Ecuador and the operation of two new offshore platform rigs
in Australia (Rig 453, an offshore platform workover rig constructed in 1995,
and Rig 489, an offshore platform drilling rig constructed in 1996 which is
owned by Pool Malaysia). See "-- Acquisitions -- Antah Drilling Sdn. Bhd."
 
     Revenues.  Revenues were $348.6 million in 1996, compared to $277.3 million
in 1995. This increase was attributable to (i) the inclusion of revenues for the
entire year of 1996 from rigs and equipment acquired in the June 1995 GPC
acquisition (see "-- Acquisitions -- Golden Pacific Corp."), (ii) higher
activity and increased rates for the jackup rigs, increased rates for the
platform rigs and increased labor contract activity in the Gulf of Mexico, (iii)
a full year's revenues for Rig 453 in Australia, (iv) higher land drilling
activity in Ecuador, (v) the inclusion since October 1996 of revenues from the
two offshore rigs owned by Pool Malaysia (see "-- Acquisitions -- Antah Drilling
Sdn. Bhd."), (vi) the inclusion since August 1996 of revenues from the Argentina
rigs acquired in the PIASA acquisition (see "-- Acquisitions -- Pool
International Argentina S.A."), and (vii) higher revenues from the winter
operation of an Arctic land drilling rig that had been on standby status for all
of 1995.
 
     Domestic onshore well-servicing and production services revenues increased
$26.6 million or 14% in 1996 from 1995, chiefly as a result of the GPC
acquisition. Domestic onshore rig utilization was 52% in both 1996 and 1995.
Domestic onshore well-servicing rig hours increased from approximately 1,003,000
in 1995 to approximately 1,119,000 in 1996, due primarily to the GPC
acquisition. In 1996, Gulf of Mexico offshore workover and drilling revenues
increased $21.1 million or 56%, international operations revenues increased
$19.3 million or 73%, and Alaska operations revenues increased $4.2 million or
21%, compared to 1995.
 
     Earnings Attributable to Unconsolidated Affiliates.  Earnings attributable
to unconsolidated affiliates were $2.2 million in 1996, compared to $3.0 million
in 1995. Earnings attributable to Pool Arabia, Ltd., the Company's Saudi Arabia
affiliate, decreased $0.6 million from 1995 to $1.7 million in 1996 primarily as
a result of higher margins earned on rig moves during 1995. Earnings from Antah
Drilling (now Pool Malaysia) ceased to be included in earnings attributable to
unconsolidated affiliates immediately following the Company's purchase of its
partner's interest in October 1996.
 
     Costs and Expenses.  The Company's costs and expenses were $333.0 million
in 1996, compared to $274.6 million in 1995; however, as a percentage of
revenues, operating expenses declined to 77% of revenues in 1996 from 79% of
revenues in 1995. The increase in costs and expenses was chiefly attributable to
the inclusion in 1996 of a full year's costs and expenses related to the rigs
and equipment obtained in the June 1995 acquisition of GPC. In addition, costs
and expenses increased due to (i) the higher jackup rig and labor contract
activity in the Gulf of Mexico, (ii) a full year's operating costs for Rig 453
in Australia, (iii) higher land drilling activity in Ecuador, (iv) the inclusion
since October 1996 of costs and expenses related to the rigs owned by Pool
Malaysia, (v) the inclusion since August 1996 of costs and expenses related to
the Argentina rigs owned by PIASA, (vi) higher costs and expenses relating to
the operation of the Arctic land drilling rig that had been on standby status
for all of 1995, and (vii) higher corporate expenses due to increased bonus and
supplementary executive retirement plans expenses. Costs and expenses in 1995
included $0.6 million of expenses related to the GPC acquisition, primarily for
yard closings.
 
     Other Income -- Net.  Other income-net was $0.8 million higher in 1996 than
in 1995 primarily due to interest income earned on temporary cash investments.
 
     Interest Expense.  Interest expense was $1.0 million higher in 1996 than in
1995 primarily due to the term loan used to refinance the construction costs for
Rig 453 located in Australia, the GPC acquisition debt and the term loans
assumed in the Antah Drilling acquisition, offset partly by lower average
borrowings in 1996 under the Company's syndicated bank revolving line of credit.
 
     Income Taxes.  The Company recorded income tax expense of $7.5 million on
income before income taxes and minority interest of $17.1 million in 1996,
compared to income tax expense of $2.0 million on income before income taxes of
$5.1 million in 1995. The increase in income tax expense was primarily due to
stronger operating results in 1996 compared to 1995. The 1995 income tax expense
included the effect of
 
                                       43
<PAGE>   51
 
certain amendments to prior period U.S. federal tax returns, partly offset by
the reversal of no longer needed deferred foreign taxes for 1990 income tax
indemnities and the elimination of the Company's valuation allowance related to
its U.S. federal net operating loss carryforwards.
 
FINANCIAL CONDITION AND LIQUIDITY
 
     The Company had cash and cash equivalents of $29.4 million at March 31,
1998 compared to $19.0 million at December 31, 1997 and $21.8 million at
December 31, 1996. Working capital was $54.1 million, $59.1 million and $47.6
million at March 31, 1998 and December 31, 1997 and 1996, respectively.
 
Cash Flows
 
     The Company used a net $75.8 million for investing activities in the first
quarter of 1998, primarily for capital expenditures of $25.9 million and $50.4
million, net of cash acquired, for the purchase of Sea Mar. The Company used a
net $5.4 million for investing activities in the first quarter of 1997,
primarily for capital expenditures of $7.0 million, partially offset by $0.9
million of proceeds from dispositions of equipment. The Company's cash provided
by operating activities increased by $24.7 million in 1997 to $42.4 million,
compared to $17.7 million in 1996. This increase was primarily due to a $17.0
million increase in net income, a $6.5 million increase in depreciation and
amortization due to recent acquisitions and rig upgrades and a $6.6 million
increase in deferred income taxes resulting primarily from higher property
additions. These increases were offset in part by changes in the working capital
components including an increase in cash useage of $4.9 million in receivables
primarily as a result of higher revenues generated in 1997 and a $4.8 million
increase in cash useage related to inventory due to new international rig
contracts, offset in part by a $8.9 million decrease in cash useage for trade
accounts payable and accrued liabilities related to higher accruals for rig
construction and upgrade projects. For the year ended December 31, 1997, net
cash flows provided by operating activities were $42.4 million, compared with
$17.7 million and $23.6 million in 1996 and 1995, respectively. The Company used
a net $84.9 million for investing activities in 1997, primarily for capital
expenditures of $60.4 million, including $9.1 million for the purchase and
modification of a jack-up workover rig and $8.3 million toward the construction
of a new platform drilling rig, both for operation in the Gulf of Mexico. Cash
used for investing activities in 1997 also included $28.9 million, net of cash
acquired, for the purchase of Trey, $3.5 million, net of cash acquired, for the
purchase of A.A., and $0.4 million, net of cash acquired, for the purchase of
DA&S, partially offset by $6.8 million of proceeds from dispositions of
equipment and the return of $1.0 million of cash that had been placed in escrow
as collateral in connection with a sale and leaseback arrangement. The Company's
cash provided by operating activities decreased by $5.9 million in 1996 to $17.7
million, compared to $23.6 million in 1995. This decrease was primarily due to
changes in the working capital components including a $18.1 million increase in
cash useage for receivables primarily as a result of higher revenues generated
in 1996. This cash useage was offset in part by a $6.5 million increase in net
income, a $3.5 million increase in depreciation and amortization due to
acquisitions and a $2.9 million increase in deferred income taxes resulting
primarily from higher property additions. The Company used a net $50.6 million
for investing activities in 1996, primarily for capital expenditures of $30.7
million, including $8.4 million for the refurbishment of Rig 18. Cash used for
investing activities during 1996 also included $8.9 million, net of cash
acquired, for the purchase of 51% of Antah Drilling, $8.7 million for the
acquisition of a 51% interest in PIASA, and $4.0 million for the purchase of the
operating assets of Western Oil, offset partly by $2.3 million of proceeds from
dispositions of equipment. The Company used a net $24.1 million for investing
activities in 1995, primarily for capital expenditures of $23.4 million,
including $6.9 million for the construction of a new offshore platform workover
rig, Rig 453, which began earning revenues in Australia in the third quarter of
1995, and $3.4 million, net of cash acquired, used in connection with the GPC
acquisition and the related direct acquisition costs, partly offset by $2.4
million of proceeds from dispositions of equipment.
 
Public Equity Offering
 
     In July 1996, the Company completed the sale to the public of 4,600,000
shares of its common stock, no par value, from which it received cash proceeds
of approximately $47.5 million, net of expenses. The Company used the net
proceeds principally as follows: (i) $10.9 million in connection with the August
1996 PIASA

acquisition, (ii) approximately $9 million in connection with the October 1996
Antah Drilling acquisition, (iii) $4.5 million in connection with the June 1996
Western Oil asset acquisition, (iv) $8.4 million in connection with the
refurbishment of Rig 18, a previously idle platform drilling rig in the Gulf of
Mexico, and (v) for repayment of debt under the Company's syndicated bank
revolving line of credit and general corporate purposes. The amounts described
above include both acquisition expenditures and related working capital
advances.
 
Long-Term Debt
 
     $150 Million Senior Subordinated Notes.  On March 31, 1998, the Company
completed a private placement of 8 5/8% Senior Subordinated Notes in the
aggregate principal amount of $150 million (see Note 4 to the Interim Condensed
Consolidated Financial Statements and "-- Notes Offering"). The Company incurred
$4.2 million of debt financing costs during the first three months of 1998 in
connection with the Notes Offering.
 
     $180 Million Credit Agreement. In March 1998, concurrent with the issuance
of the Notes and the closing of the Sea Mar Acquisition, the Company executed an
amendment to its Credit Agreement to increase maximum availability thereunder
from $130 million to $180 million, including up to $15 million that may be used
to support letters of credit. See "Description of Other Indebtedness."
 
     Borrowings under the Credit Agreement bear interest, at the Company's
option, at either (i) the Base Rate (defined as the administrative agent bank's
prime lending rate or 1/2 of 1% in excess of the federal funds rate) plus a
margin ranging from zero to .50%, or (ii) the Eurodollar Rate (equivalent to the
London Interbank Offered Rate plus a margin ranging from 1% to 1.75% with the
Company's choice of a one-, two-, three- or six-month interest period. The
applicable margin for each interest option depends on the Company's leverage
ratio for the fiscal quarter preceding the interest period; however, through
September 1998, the applicable Eurodollar margin shall not be less than 1.50%.
Based upon the Company's leverage ratio at December 31, 1997, the applicable
Eurodollar margin would have been 1.00%. The Credit Agreement will mature on
October 2, 2000 and is subject to one-year extensions at the discretion of the
Lenders. Notes issued under the Credit Agreement are prepayable at any time and
are due at expiration on October 2, 2000. The Credit Agreement imposes certain
financial covenants, including ones requiring the maintenance of a minimum net
worth, a minimum interest coverage ratio, a minimum fixed charge coverage ratio,
a maximum leverage ratio and a maximum debt-to-equity ratio. It also imposes
certain other restrictions, including ones relating to liens, other
indebtedness, asset sales, investments, acquisitions or mergers and the payment
of dividends. Advances under the Credit Agreement are secured by a pledge of 66%
of the capital stock of certain of the Company's foreign subsidiaries. The
Company incurred $0.5 million and $1.6 million of debt financing costs during
the first quarter of 1998 and during 1997, respectively in connection with the
Credit Agreement, which are being amortized over the term of the agreement.
 
     For a more detailed description of the Credit Agreement and a description
of other long-term debt, see "Description of Other Indebtedness."
 
Capital Expenditures
 
     The Company anticipates that 1998 capital expenditures, excluding business
acquisitions, will consist of (i) approximately $50 million for additions and
improvements to its existing rig fleet, (ii) approximately $10 million toward
the upgrade of an Arctic land drilling rig, (iii) approximately $14 million
toward the construction of a new Arctic land drilling rig, (iv) approximately
$4.5 million for the electrification and upgrade of a platform workover rig
located in the Gulf of Mexico and (v) $2.3 million for the purchase of two
jack-up workover rigs located in the Gulf of Mexico that the Company currently
leases.
 
     In addition, the Company expects to make capital expenditures in 1998 of
approximately $17 million with respect to Sea Mar's vessel fleet, including
approximately $16 million for payment of the balance of the purchase price for
two vessels currently under construction which are scheduled for delivery in
late 1998.
 
     The Company anticipates that these expenditures will be financed by
internally generated funds and borrowings under the Credit Agreement as needed.
Acquisitions of additional assets and businesses are
                                       45
<PAGE>   53
 
expected to continue to be an important part of the Company's strategy for
growth. The Company believes that it would, under certain circumstances, need to
obtain additional debt and/or equity financing to fund such acquisitions.
 
OTHER MATTERS
 
Accounting Standards
 
     In February 1998, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standard ("SFAS") No. 132, "Employers'
Disclosures about Pensions and Other Postretirement Benefits." This statement
standardizes the disclosure requirements for pensions and other postretirement
benefits to the extent practicable, requires additional information on changes
in the benefit obligations and fair values of plan assets and eliminates certain
disclosures no longer considered useful. The Company plans to adopt this
statement in the fourth quarter of 1998. Its adoption is not expected to have a
material effect on the Company's financial position or results of operations and
any effect will be limited to the form and content of the disclosure it
requires.
 
     In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
Income." This statement establishes standards for reporting and display of
comprehensive income and its components. The Company adopted this statement in
the first quarter of 1998 and there was no effect on the Company's financial
statements.
 
     Also in June 1997, the FASB issued SFAS No. 131, "Disclosures about
Segments of an Enterprise and Related Information." This statement establishes
standards for the way that public business enterprises report information about
operating segments in interim and annual financial statements. The Company plans
to adopt this statement in the fourth quarter of 1998. Its adoption is not
expected to have a material effect on the Company's financial statements, and
any effect will be limited to the form and content of the disclosure it
requires.
 
     In February 1997, the FASB issued SFAS No. 128, "Earnings Per Share," which
establishes new standards for computing and presenting earnings per share. This
statement was adopted in the fourth quarter of 1997 and had no material effect
on the Company's computation of earnings per share.
 
     In March 1995, the FASB issued SFAS No. 121, "Accounting for the Impairment
of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of." This
statement requires that long-lived assets including certain identifiable
intangibles held and used by the Company be reviewed for impairment whenever
events or changes in circumstances indicate that the carrying amount of an asset
may not be recoverable. The adoption of this statement in 1996 had no effect on
the Company's financial statements.
 
     In October 1995, the FASB issued SFAS No. 123, "Accounting for Stock-Based
Compensation" ("SFAS 123"), which sets forth alternative accounting and
disclosure requirements for stock-based compensation arrangements. SFAS 123 does
not rescind the existing accounting for employee stock-based compensation under
APB Opinion No. 25, "Accounting for Stock Issued to Employees" ("APB 25").
Companies may continue to follow the current accounting to measure and recognize
employee stock-based compensation; however, SFAS 123 requires disclosure of pro
forma net income and earnings per share that would have been reported under the
"fair value" based recognition provisions of SFAS 123. The Company has elected
to continue to follow the provisions of APB 25 for employee compensation and has
disclosed the pro forma information required under SFAS 123 in Note 2 of Notes
to Consolidated Financial Statements.
 
San Angelo Lease Commitment
 
     The Company has an operating lease, effective through March 2003, for a
65-acre facility at San Angelo, Texas, which it previously used for rig and
equipment manufacturing and storage. Annual lease payments are $2.2 million
through March 1998 and $4.4 million thereafter for the remaining five years of
the lease. Effective October 1, 1994, the Company vacated this facility and
subleased it in its entirety for $0.5 million per year under an operating
sublease which expired in September 1997. In September 1988, the Company,
anticipating that it would not be able to fully utilize the facility for a
period of years, accrued a $15.9 million liability for the
 
                                       46
<PAGE>   54
 
expected underutilization. After September 1988, the cost associated with the
unutilized portion of the facility was charged against this accrued liability,
which as of the fourth quarter of 1994 had substantially been used. In the
fourth quarter of 1994, the Company recorded a provision for leasehold
impairment of $23.6 million, as the Company did not anticipate utilizing any of
this facility in its future operations nor did it expect to be able to sublease
this facility to third parties for an amount equivalent to the annual lease
payments. This provision recognized all future lease expense, net of anticipated
sublease income. Future lease payments will be charged against such provision.
 
Impact of The Year 2000 Issue
 
     The Year 2000 Issue is the result of computer programs having been written
using two digits rather than four to define the applicable year. Any computer
programs that have date-sensitive software may recognize a date using "00" as
the year 1900 rather than the year 2000. This could result in a system failure
or miscalculations causing disruptions of operations, including, among other
things, a temporary inability to process transactions, send invoices, or engage
in similar normal business activities.
 
     The Company is currently assessing what computer software will require
modification or replacement so that its computer systems will properly utilize
dates beyond December 31, 1999. The operation of the Company's rigs, however,
will not be directly affected by this Year 2000 Issue, since only a few of the
Company's rigs have any functions controlled by computer. The software vendors
for the Company's two primary computer systems, the accounting system for its
domestic operations and the human resources/payroll system, have recently issued
releases which are Year 2000 compliant. The Company plans to implement these new
releases before the end of 1998. The Company has several smaller computer
systems, particularly in its foreign locations, which are expected to be
modified or replaced by mid-1999 in order to become Year 2000 compliant. The
Company will use both internal and external resources to reprogram, or replace,
and test its software for Year 2000 modifications. The Company presently
believes that with modifications to existing software and conversions to new
software, the Year 2000 Issue can be resolved in a timely manner. However, if
such modifications and conversions are not made, or are not completed timely,
the Year 2000 Issue could have a material impact on the operations of the
Company. The Company presently does not believe that costs to become Year 2000
compliant will have a material adverse effect on the Company's financial
statements.
 
     The costs of becoming Year 2000 compliant and the dates on which the
Company plans to complete the Year 2000 modifications are based on management's
best estimates, which were derived utilizing numerous assumptions regarding
future events, including the continued availability of certain resources, third
party modification plans and other factors. However, there can be no guarantee
that these cost or time estimates will be achieved, and actual results could
differ materially. Specific factors that might cause such material differences
include, but are not limited to, the availability of personnel trained in this
area, the ability to locate and correct all relevant computer codes, and similar
uncertainties.

                                    BUSINESS
 
     Pool Energy Services Co. is a leading worldwide provider of well-servicing,
workover and drilling rig services and related transportation services for both
land and offshore markets to a diverse group of multi-national, foreign national
and independent oil and natural gas producers. The Company performs the ongoing
maintenance and major overhauls necessary to optimize the level of production
from existing oil and natural gas wells and provides certain ancillary services
during the drilling and completion of new oil and natural gas wells. The Company
also provides contract drilling services in Alaska, the Gulf of Mexico, certain
international locations and on occasion in the lower forty-eight states.
Typically, the Company provides a well-servicing, workover or drilling rig, the
crew to operate the rig and such other specialized equipment as may be needed to
meet a customer's requirements. In addition, the Company owns a fleet of
offshore support vessels that provides marine transportation of drilling
materials, supplies and crews for offshore rig operations and support for other
offshore facilities.
 
     As of March 31, 1998, the Company's worldwide fleet included 791 land
well-servicing/workover rigs, 27 land drilling rigs and 27 offshore rigs (15
platform workover rigs, five platform drilling rigs and seven jack-up rigs). The
Company also owns or leases and operates 370 fluid hauling trucks, 1,060 fluid
storage tanks, 14 salt water disposal wells and other auxiliary equipment used
in its domestic operations. The Company also operates a fleet of 23 support
vessels to complement its offshore rig fleet.
 
     The Company operates both domestically and internationally. In the United
States, the Company operates in several oil and natural gas producing states,
with specific concentration onshore in Texas, California, Oklahoma, New Mexico,
North Dakota, Montana, Utah and Alaska, and offshore in the Gulf of Mexico,
offshore California and in the Cook Inlet of Alaska. Revenues from domestic
operations represented approximately 85% of the Company's pro forma 1997
revenues. International markets where the Company has an established presence
include land operations in Argentina, Ecuador, Guatemala, Oman, Pakistan and
Saudi Arabia and offshore operations in Australia, Malaysia and Saudi Arabia.
Revenues from international operations represented approximately 15% of the
Company's pro forma 1997 revenues.
 
BUSINESS STRATEGY
 
     The Company's business strategy is to further strengthen its competitive
position and market share in the oilfield services industry, in order to achieve
growth in revenues, earnings and EBITDA. Key components of the Company's
business strategy include: (i) pursuing expansion opportunities in existing core
market areas through selective acquisitions that result in expanded market
presence and in consolidation cost savings; (ii) upgrading and enhancing the
capabilities of the Company's existing rig fleet and constructing specialized
rigs and equipment to operate in markets with high levels of activity and strong
pricing fundamentals; (iii) offering a broad and integrated array of additional
services and equipment that complement the Company's businesses in its existing
locations; and (iv) entering new foreign markets that offer significant
development and production activity.
 
STRATEGY IMPLEMENTATION
 
     In addition to the Sea Mar Acquisition, notable events in the
implementation of the Company's business strategy include:
 
Expansion of Domestic Onshore Operations
 
     - In November 1997, the Company acquired A.A. for $4.1 million in cash.
       This acquisition included 18 oilfield trucks, one salt water disposal
       well and related equipment based in Hobbs, New Mexico.
 
     - In October 1997, the Company purchased the operating assets (including
       three coiled tubing units, six pump trucks and a bulk cementing plant) of
       Anchor Cementing Service in California for $2.5 million in cash.
 
     - In October 1997, the Company acquired Trey and certain associated
       operating assets for $31.3 million in cash. Prior to the acquisition,
       Trey, through its wholly-owned subsidiary R & H, operated a fleet of
                                       48
<PAGE>   56
 
       approximately 67 land well-servicing rigs, 104 oilfield trucks, 430 fluid
       storage tanks and five brine and disposal wells in the Permian Basin of
       West Texas.
 
     - In August 1997, the Company purchased the operating assets (including
       seven land well-servicing rigs) of Dean's Well Servicing, Inc. in
       Oklahoma for $1.0 million in cash.
 
     - In June 1997, the Company acquired DA&S for $10.5 million. This
       acquisition included among other assets, a fleet of 37 land
       well-servicing rigs operating from yards in Hobbs and Eunice, New Mexico
       and Andrews, Texas.
 
     - In June 1996, the Company purchased the operating assets (including
       approximately 23 land well-servicing rigs) of Western Oil in the
       Williston Basin for approximately $4.0 million in cash.
 
     - In June 1995, the Company acquired GPC for $18.8 million. This
       acquisition included, among other assets, the GPC fleet of approximately
       155 land well-servicing rigs in California. The Company is now the market
       leader in California with a total of 259 land well-servicing rigs.
 
Expansion of Gulf of Mexico Offshore Operations
 
     - In February 1998, the Company completed construction of a new 1,500
       horsepower offshore platform drilling rig, Rig 16, at a cost of
       approximately $12 million, and began operation of such rig in the Gulf of
       Mexico for Forcenergy, Inc. under a two-year contract.
 
     - In August 1997, the Company acquired an offshore jack-up workover rig for
       $8.2 million in cash, for operation in the Gulf of Mexico.
 
     - In March 1996, the Company received a term contract for Rig 18, a
       previously idle platform drilling rig, which was refurbished for a cost
       of approximately $8.4 million and placed in service in the Gulf of
       Mexico.
 
Expansion of Alaska Operations
 
     - The Company is procuring the materials and equipment necessary to convert
       one of its Arctic exploration rigs for development drilling. As currently
       configured, the rig is generally limited to working only in the winter
       season; following the upgrade, the rig will be capable of year-round
       work. The upgrade, expected to cost $15 million, will begin after the rig
       completes its winter operations in April 1998. This rig is expected to
       begin year-round drilling operations in September 1998, under a
       three-year contract with ARCO Alaska, Inc. on the North Slope of Alaska.
 
     - The Company is currently procuring materials to construct a new 1,000
       horsepower Arctic land drilling rig at an estimated cost of $13.8
       million. This new rig is expected to begin year-round operations on the
       North Slope of Alaska under a three-year contract for ARCO Alaska, Inc.
       in January 1999.
 
     - In February 1998 the Company commenced operations for BP Exploration
       (Alaska), Inc. on the North Slope of Alaska under a five-year contract
       using one of its Arctic drilling rigs which was recently upgraded at a
       cost of $5.3 million to enable it to operate on the North Slope.
 
     - In September 1994, the Company acquired the 60.7% partnership interest
       that it did not already own in Pool Arctic Alaska for $12.1 million in
       cash. This acquisition expanded the Company's wholly-owned Alaska
       operation to include the three specialized Arctic land drilling rigs and
       related equipment formerly owned by the partnership.
 
Expansion of Saudi Arabia and Other International Operations
 
     - In April 1998, the Company's Saudi Arabia joint venture company, Pool
       Arabia, Ltd. ("Pool Arabia"), began operating a 1,500 horsepower land
       drilling rig in Saudi Arabia under a three-year contract. The Company
       upgraded and transported this rig from the United States to Saudi Arabia
       at a cost of $9.4 million and is leasing the rig to Pool Arabia.
 
                                       49
<PAGE>   57
 
     - In February 1998, Pool Arabia began operating a 1,000 horsepower land
       drilling rig in Saudi Arabia under a three-year contract. Pool Arabia,
       upgraded and transported this rig from Oman to Saudi Arabia at a cost of
       $3.6 million. The Company is leasing this rig to Pool Arabia.
 
     - In October 1997, Pool Arabia acquired a 3,000 horsepower land drilling
       rig and three land workover rigs for $9.0 million from a competitor in
       Saudi Arabia. In March 1998, after a $7.8 million upgrade, the drilling
       rig began a new three-year contract. One of the workover rigs is
       currently working under a three-year contract that commenced in March
       1997.
 
     - In October 1996, the Company acquired the 51% interest that it did not
       already own in Antah Drilling and repaid indebtedness that Antah Drilling
       owed to the Company's former partner in that venture for a total of $9.0
       million in cash. The assets of Antah Drilling, now Pool International
       (Malaysia) Sdn. Bhd. ("Pool Malaysia"), include Rig 489, a 2,000
       horsepower offshore platform drilling rig, which commenced operations in
       August 1996 on a three-year term contract for Esso Australia, Ltd. in
       Australia and an offshore platform workover rig currently operating under
       a term contract in Malaysia.
 
     - In August 1996, the Company acquired for approximately $8.7 million in
       cash a 51% interest in PIASA, a newly formed Argentina corporation which
       provides well-servicing, workover and drilling services in Argentina.
       PIASA owns nine land drilling rigs and 11 land workover rigs, all of
       which are located in Argentina.
 
DESCRIPTION OF SERVICES PROVIDED
 
     The Company estimates that there are approximately 900,000 producing oil
wells in the world today, of which approximately 570,000 are in the United
States. In addition, there are approximately 300,000 producing natural gas wells
in the United States and a large number in the rest of the world. While some
wells in the United States flow oil to the surface without mechanical
assistance, most are in mature production areas that require pumping or some
other form of artificial lift. Pumping oil wells characteristically require more
maintenance than flowing wells due to the operation of the mechanical pumping
equipment installed. The extent and type of services provided by the Company on
producing wells is dependent upon many variables. The following is a summary of
the services the Company provides.
 
Well-Servicing/Maintenance Services
 
     The Company provides maintenance services on the mechanical apparatus used
to pump or lift oil from producing wells. These services include, among other
things, repairing and replacing pumps, sucker rods and tubing. The Company
provides the rigs, equipment and crews for these tasks, which are performed on
both oil and natural gas wells, but which are more commonly required on oil
wells. Well-servicing rigs have the same basic components as drilling rigs
(i.e., a derrick, a hoisting mechanism and an engine). Many of these rigs also
have pumps and tanks that can be used for circulating fluids into and out of the
well. Maintenance jobs typically take less than 48 hours to complete.
 
Workover Services
 
     In addition to needing periodic maintenance, producing oil and natural gas
wells occasionally require major repairs or modifications, called "workovers."
Workovers may be done, for example, to remedy equipment failures, deepen a well
in order to reach a new producing reservoir, plug back the bottom of a well to
reduce the amount of water being produced with the oil and natural gas, clean
out and recomplete a well if production has declined, repair leaks, or convert a
producing well to an injection well for secondary or enhanced recovery projects.
These extensive workover operations are normally carried out with a well-
servicing rig that includes additional specialized accessory equipment, which
may include rotary drilling equipment, mud pumps, mud tanks and blowout
preventers, depending upon the particular type of workover operation. Most of
the Company's well-servicing rigs are designed and can be equipped to handle the
more complex workover operations. A workover may last anywhere from a few days
to several weeks.
 
                                       50
<PAGE>   58
 
Completion Services
 
     The kinds of activities necessary to carry out a workover operation are
essentially the same as those that are required to "complete" a well when it is
first drilled. The completion process may involve selectively perforating the
well casing at the depth of discrete producing zones, stimulating and testing
these zones and installing down-hole equipment. Oil and gas production companies
often find it more efficient to move a larger and more expensive drilling rig
off location after an oil or natural gas well has been drilled and to move in a
specialized well-servicing rig to perform completion operations. The Company's
rigs are often used for this purpose. The completion process may require from a
few days to several weeks.
 
Contract Drilling Services
 
     The Company provides contract drilling services to oil and natural gas
operators in all the markets in which it operates, except that the amount of
such services it provides onshore in the lower forty-eight states is minimal.
Workover rigs can be used for drilling, although specialized drilling rigs are
typically used for such operations. The Company also provides specialized
accessory equipment, including pumps, rotary drilling equipment, top drive
units, trucks, camps and cranes. Several of the Company's land drilling rigs are
equipped for self-sustained operations in remote areas in Alaska and certain
overseas locations.
 
Offshore Services
 
     The Company generally utilizes its offshore jackup and platform rigs to
service wells located on platforms. Platform rigs consist of well-servicing
and/or drilling equipment and machinery arranged in modular packages which are
transported to and assembled and installed on fixed offshore platforms owned by
the customer. Fixed offshore platforms are steel tower-like structures that
stand on the ocean floor, with the top portion, which is above the water level,
forming the foundation upon which the platform rig is placed. Certain of the
Company's heavy platform rigs are capable of operating at well depths of as much
as 18,000 feet or more, and several of the Company's platform rigs are
specifically designed for drilling. The Company is performing an increasing
amount of drilling and horizontal re-entry services utilizing portable top
drives, enhanced pumps and solids control equipment for drilling fluids. Jackup
rigs are mobile, self-elevating platforms equipped with legs that can be lowered
to the ocean floor until a foundation is established to support the hull, which
contains the drilling and/or workover equipment, jacking system, crew quarters,
loading and unloading facilities, storage areas for bulk and liquid materials,
helicopter landing deck and other related equipment. The rig legs may operate
independently or have a mat attached to the lower portion of the legs in order
to provide a more stable foundation in soft bottom areas. All of the Company's
jackup rigs are cantilever design -- a feature that permits the drilling
platform to be extended out from the hull, allowing it to perform drilling or
workover operations over fixed platforms.
 
     The Company's fleet of offshore support vessels provides marine
transportation of drilling materials, supplies and crews for offshore rig
operations and support for other offshore facilities. In addition, the Company
provides offshore logistical support to drilling and workover operations,
pipelaying and other construction, production platforms and geophysical
operations.
 
Production and Other Specialized Services
 
     The Company provides other specialized services that are required, or can
be used effectively, in conjunction with the previously described basic
services. The main additional services are production services, consisting of
the provision of onsite temporary fluid-storage facilities, the provision,
removal and disposal of specialized fluids used during certain completion and
workover operations, and the removal and disposal of salt water that is often
produced in conjunction with the production of oil and natural gas. The Company
also provides plugging services for wells from which the oil and natural gas has
been depleted and further production has become uneconomical.

BUSINESS BY GEOGRAPHIC AREA
 
     Financial data by geographic area for the three years ended December 31,
1997 are presented in Note 11 of Notes to Consolidated Financial Statements.
 
BUSINESS BY SERVICE LINE
 
     The Company operates in only one business segment -- the oilfield services
industry. Within that segment, the Company conducts business in the following
distinct markets or business lines: domestic onshore well-servicing and
production services, Gulf of Mexico offshore workover/drilling, offshore support
vessel operations, international workover/drilling and related services and
Alaska onshore and offshore workover/ drilling.
 
Domestic Onshore
 
     The Company's domestic onshore operation, which provides well-servicing,
workover and production services, has locations in many of the major oil and
natural gas producing fields in the lower forty-eight states. This operation
currently provides services in 11 states and is divided into two separate
geographic divisions: (i) the Central division (principally Texas and Oklahoma)
and (ii) the California division. The Company's domestic onshore operation has
758 well-servicing rigs, of which 340 are located in Texas, 259 in California,
61 in Oklahoma, 38 in New Mexico, 27 in North Dakota, and 33 in Montana,
Arkansas, Utah and Louisiana. During the year ended December 31, 1997,
approximately 60% of the Company's domestic onshore rig hours were related to
well-servicing/maintenance with the balance related to workover, completion and
plugging operations.
 
     In general, well-servicing rigs are provided to customers on a call-out
basis. The Company is paid an hourly rate and work is generally performed five
days a week during daylight hours.
 
     The Company's domestic onshore operation also provides production services
consisting chiefly of fluid hauling and fluid storage tank rental. The
production services assets, located primarily in Texas, consist of 370 fluid
hauling trucks and 14 salt water disposal wells, which are utilized for the
transportation and disposal of drilling and used completion fluids and salt
water produced from operating wells, and 1,060 fluid storage tanks, which are
utilized for the storage of fluids used in the fracturing of producing zones
during the completion or workover of wells.
 
Gulf of Mexico Offshore
 
     Offshore in the Gulf of Mexico, the Company provides workover,
well-servicing, completion and drilling services with its fleet of 15 platform
rigs, including newly constructed Rig 16, and six jack-up rigs. The Company also
provides crews to oil and natural gas well operators under labor contracts.
During the year ended December 31, 1997, approximately 71% of the Company's Gulf
of Mexico offshore rig hours were related to workover, well-servicing and
completion operations with the balance related to contract drilling. Offshore
operations are normally conducted 24 hours a day, seven days a week, under a
term contract that is either for a specific period of time or until a program of
work is completed. The Company is paid on a daily rate basis for its services.

     As of March 31, 1998, the average age of the Company's rig fleet (based on
age of construction or refurbishment) by service line was as follows: domestic
onshore well-servicing rig fleet -- 20 years; Gulf of Mexico offshore rig
fleet -- 4 years; International: land rig fleet -- 10 years and offshore rig
fleet -- 6 years; and Alaska rig fleet -- 8 years. The components of the rigs
such as engines and transmissions are routinely replaced every three to five
years. The Company believes that the vast majority of its rig fleet is in good
operating condition.

AHTS....................      1       Used to tow rigs to offshore locations and position anchors
                                      of floating drilling rigs and pipelaying vessels. The vessel
                                      is 200 feet long with 6,140 horsepower and could be
                                      converted to a larger supply vessel if market conditions
                                      warranted.
Supply..................     13       Used as the primary freight-carrying vessel for drill pipe,
                                      tubing, casing, drilling mud and other equipment to drilling
                                      rigs and production platforms. One vessel is bareboat
                                      chartered. Lengths range from 166 to 220 feet.
Mini-Supply.............      7       Used primarily in support of well service and production
                                      operations, such as moving offshore pipe, fluids and
                                      equipment for offshore workovers. Lengths range from 130 to

     In addition, Sea Mar has a contract with a marine shipbuilder for the
construction of ten offshore support vessels at an estimated aggregate cost of
$77.6 million, net of deposits. The ten new vessels are scheduled to be
delivered between late 1998 and early 2000. Each new vessel is 200 or more feet
in length and 4,000 or more in horsepower. All of the new vessels have design
features, including modifiable length and propulsion characteristics, which
allow them to be supplemented with dynamic positioning equipment. Such features
will enhance the ability of these vessels to provide services to floating
drilling rigs in the deep water region of the Gulf of Mexico.
 
OTHER PROPERTIES
 
     The Company's corporate offices are located in Houston, Texas, where the
Company leases office space from ENSERCH Corporation at market rates under an
agreement that expires in December 2002. The Company also leases from an
unrelated party a 65-acre former rig and equipment manufacturing and storage
facility in San Angelo, Texas, which includes approximately 245,000 square feet
of buildings and other structural facilities. The annual lease payments are $2.2
million through March 1998 and $4.4 million thereafter for the remaining five
years of the lease. Effective October 1, 1994, the Company vacated this facility
and subleased it in its entirety for $0.5 million per year under an operating
sublease which expired in September 1997. Based on a conclusion that none of the
facility is likely to be used in its future operations, the Company, in the
fourth quarter of 1994, recorded a provision of $23.6 million to recognize all
future lease expense, net of anticipated sublease income. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations -- San
Angelo Lease Commitment." The Company owns 41 and leases 66 domestic office and
yard locations of which nine locations are not currently used. Internationally,
the Company leases office and yard facilities at 12 locations and owns
facilities at five locations, all of which are currently used. In Alaska, the
Company leases an office and yard facility in Anchorage and a yard facility on
the North Slope.
 
     As partial consideration for the acquisition of DA&S in 1997 and GPC in
1995, the Company issued notes which are collateralized by the well-servicing
rigs and related equipment and certain real property obtained in the respective
acquisitions.
 
EMPLOYEES
 
     At March 31, 1998, the Company had 6,721 employees, of whom 947 were
employed by unconsolidated affiliates. Approximately 181 employees in Argentina
and 94 employees in Australia are represented by collective bargaining units.
Management believes that the Company's relationship with its employees is
excellent.
 
LEGAL PROCEEDINGS
 
     The Company from time to time is involved in ordinary and routine
litigation incidental to its business, which often involves claims for
significant monetary amounts, some, but not all, of which would be covered by
 
                                       57
<PAGE>   65
 
insurance. In the opinion of management, none of the existing litigation will
have any material adverse effect on the Company. See also "-- Environmental
Regulation and Claims and Other Governmental Regulation."
 
     The Company previously disclosed, at the time it announced signing of the
purchase agreement for the Sea Mar Acquisition, that Sea Mar had entered into
term charter agreements with respect to four out of the ten new vessels that Sea
Mar has under construction. Subsequently, Sea Mar was notified by Rowan
Companies, Inc. ("Rowan") that it was repudiating and terminating such charter
agreements. Sea Mar and its prior owner, Mr. Gonsoulin, sued Rowan seeking
specific performance and any damages that may result from wrongful breach of the
charter agreements. Rowan subsequently filed suit seeking a declaration that the
charter agreements are void. Regardless of the outcome of this matter, the
Company fully expects that this development will not have a material adverse
impact on the Company.
 
ENVIRONMENTAL REGULATION AND CLAIMS AND OTHER GOVERNMENTAL REGULATION
 
     The Company's well-servicing, workover and production services operations
routinely involve the handling of significant amounts of waste materials, some
of which are classified as hazardous substances. The Company's operations and
facilities are subject to numerous state and federal environmental laws, rules
and regulations, including, without limitation, laws concerning the containment
and disposal of hazardous substances, oilfield waste and other waste materials,
the use of underground storage tanks and the use of underground injection wells.
The Company's offshore support vessel operations also are subject to federal,
state and local laws and regulations which control the discharge of pollutants
into the environment and which otherwise relate to environmental protection.
Other laws regulate the activities of offshore service vessels, require vessel
owners and operators to demonstrate financial and operational responsibility and
provide for certain limitations on the liability of vessel owners and operators.
Failure to comply with these laws, rules, and regulations may result in civil
and even criminal actions.
 
     The Company employs personnel responsible for monitoring environmental
compliance and arranging for remedial actions that may be required from time to
time and also uses outside experts to advise on and assist with the Company's
environmental compliance efforts. Costs incurred by the Company to investigate
and remediate contaminated sites are expensed unless the remediation extends the
useful lives of the assets employed at the site. Remediation costs that extend
the useful lives of the assets are capitalized and amortized over the remaining
useful lives of such assets. Liabilities are recorded when the need for
environmental assessments and/or remedial efforts become known or probable and
the cost can be reasonably estimated.
 
     Laws protecting the environment have generally become more stringent than
in the past and are expected to continue to do so. Environmental laws and
regulations typically impose "strict liability," which means that in some
situations the Company could be exposed to liability for cleanup costs, natural
resource damages and other damages as a result of conduct of the Company that
was lawful at the time it occurred or conduct of, or conditions caused by, prior
operators or other third parties. Cleanup costs and other damages arising as a
result of environmental laws, and costs associated with changes in environmental
laws and regulations could be substantial and could have a material adverse
effect on the Company's financial condition. From time to time, claims have been
made and litigation has been brought against the Company under such laws.
However, the costs incurred in connection with such claims and other costs of
environmental compliance have not had any material adverse effect on the
Company's operations or financial statements in the past, and management is not
currently aware of any situation or condition that it believes is likely to have
any such material adverse effect in the future.
 
     Under the Comprehensive Environmental Response, Compensation and Liability
Act ("CERCLA"), also known as Superfund, and related state laws and regulations,
joint and several liability can be imposed without regard to fault or the
legality of the original conduct on certain classes of persons that contributed
to the release of a "hazardous substance" into the environment. Under CERCLA,
such persons may be liable for the costs of cleaning up the hazardous substances
that have been released into the environment and for damages to natural
resources, and it is not uncommon for the neighboring land owners and other
third parties to file claims for personal injury, property damage and recovery
of response costs allegedly caused by the hazardous substances released into the
environment. The Company has been notified of its possible
 
                                       58
<PAGE>   66
 
responsibility with respect to the cleanup of a federal national priority list
("NPL") site and a state abandoned site, which were formerly operated by parties
unrelated to the Company as oilfield waste disposal facilities. In addition, the
Company was named as a potentially responsible party with respect to the cleanup
of one other site which was formerly operated by various parties unrelated to
the Company as an oil refining and reclamation facility. The Company believes
that its costs to clean up the site will be less than $0.1 million. Although at
this time information regarding the Company's possible responsibility with
respect to cleanup of the federal NPL site and the state abandoned site has not
been fully developed and it is not feasible to predict such outcome with
certainty, management is of the opinion that their ultimate resolution should
not have a material adverse effect on the Company's financial position or
results of operations.
 
     Changes to federal and state environmental regulations may also negatively
impact oil and natural gas exploration and production companies, which in turn
could have a material adverse effect on the Company. For example, while the
Company currently does not handle large amounts of "hazardous wastes" (which are
subject to regulation under the federal Resource Conservation and Recovery Act
("RCRA")) in connection with its operations, legislation has been proposed from
time to time in Congress which would reclassify oil and natural gas production
wastes as RCRA hazardous wastes. If enacted, such legislation could dramatically
increase operating costs for domestic oil and natural gas companies and this
could reduce the market for the Company's services by making many wells and/or
oilfields uneconomical to operate. To date, such legislation has not made
significant progress toward enactment.
 
     With respect to Sea Mar's operations, the Company is affected by additional
governmental regulations. Under the Merchant Marine Act of 1920, as amended, if
persons other than U.S. citizens own in the aggregate in excess of 25% of the
Company's outstanding stock, Sea Mar's U.S. flagged vessels would lose the
privilege of engaging in the transportation of merchandise in the U.S. coastwise
trade. In addition, Sea Mar's operations are materially affected by federal,
state and local regulation, as well as certain international conventions and
private industry organizations. These regulations govern worker health and
safety and the manning, construction and operation of vessels. Private industry
organizations establish safety criteria and are authorized to investigate vessel
accidents and recommend approved safety standards. The failure to comply with
the requirements of any of these laws or the rules or regulations of these
agencies and organizations could have a material adverse effect on Sea Mar's
operations.
 
     The Oil Pollution Act of 1990, as amended ("OPA"), contains provisions
specifying responsibility for removal costs and damages resulting from
discharges of oil into navigable waters or onto the adjoining shorelines. Among
other requirements, OPA requires owners and operators of vessels over 300 gross
tons to provide the U.S. Coast Guard with evidence of financial responsibility
to cover the costs of cleaning up oil spills from such vessels. The Company
believes that Sea Mar has provided satisfactory evidence of financial
responsibility to the U.S. Coast Guard for all of its vessels over 300 tons. In
addition, the Outer Continental Shelf Lands Act ("OCSLA") provides the federal
government with broad discretion in regulating the leasing of offshore oil and
gas production sites. Because Sea Mar's operations rely on offshore oil and gas
exploration and production, if the government were to exercise its authority
under OCSLA to restrict the availability of offshore oil and gas leases, such an
action could have a material adverse effect on the Company's financial position
and results of operations.
 
PATENTS AND TRADEMARKS
 
     The Company owns several U.S. patents on designs for various types of
oilfield equipment and on methods for conducting certain oilfield activities.
The Company uses some of these designs and methods in the conduct of its
business. The patents expire at various times through the year 2014. The Company
also has several trademarks and service marks that it uses in various aspects of
its business. While management believes the Company's patent and trademark
rights are valuable, the expiration or loss thereof would not have a material
adverse effect on the Company's financial statements.

COMPETITIVE CONDITIONS
 
     Although the number of available rigs has materially decreased over the
past ten years, the well-servicing, workover and drilling industry remains very
competitive. The number of rigs continues to exceed demand, resulting in keen
price competition. Many of the total available contracts are currently awarded
on a bid basis, which further increases competition based on price. In all of
the Company's market areas, competitive factors also include: the availability
and condition of equipment to meet both special and general customer needs; the
availability of trained personnel possessing the required specialized skills;
the overall quality of service and safety record; and domestically, the ability
to offer ancillary services such as fluid hauling, fluid storage tank rental and
salt water disposal. As an enhancement to its competitive position, the Company
has been able to establish strategic alliances with major customers in its
domestic onshore, international and Alaska markets. Many smaller competitors may
not be able to allocate the resources necessary to enter into such alliances.
One customer, Shell Oil Company and its affiliates, accounted for approximately
11% of the Company's consolidated revenues during both 1996 and 1995. During
1997, no single customer accounted for more than 10% of the Company's
consolidated revenues.
 
     Certain competitors are present in more than one of the Company's markets,
although no one competitor operates in all of these areas. In the domestic
onshore market, the Company, with 758 land well-servicing rigs, and Key Energy
Group, Inc., with a similar number of land well-servicing rigs, are the two
largest well-servicing providers. In this market, the third largest competitor
has approximately 500 land well-servicing rigs, and numerous competitors have
smaller regional or local rig operations. In each of its domestic onshore
locations in the lower forty-eight states, the Company competes with several
firms of varying size. In the Gulf of Mexico, the Company is among five
principal competitors providing workover/maintenance services, the two largest
of which are Pride Petroleum Services, Inc. and an affiliate of Nabors
Industries, Inc. Internationally, the Company competes directly with various
competitors at each location where it operates, none of which is dominant. In
Alaska, the Company has four major competitors, the largest of which are Nabors
Industries, Inc. and Doyon Drilling, Inc.
 
     The Company faces significant competition with respect to the operations of
Sea Mar. The marine support services industry is highly competitive. Competitive
factors in the marine support services industry include (i) price, (ii) service,
including reputation of vessel operators and crews, (iii) availability of
vessels of the types and sizes needed by the customer and (iv) quality of
vessels and related equipment. Tidewater, Inc. is the dominant competitor in the
Gulf of Mexico marine support services market.

                       DESCRIPTION OF OTHER INDEBTEDNESS
 
     Prior to the Notes Offering, certain of the Company's outstanding
indebtedness was retired with borrowings under the Credit Agreement and with
other available cash. See "-- Debt Retired Prior to and Concurrent with the
Notes Offering". The Company used $54.1 million in proceeds from the Notes
Offering to reduce the outstanding balance under the Credit Agreement. As of the
date hereof, the Company (excluding unconsolidated affiliates) has, in addition
to the Notes, indebtedness outstanding as shown below:
 
     $180 Million Credit Agreement. On September 30, 1997, the Company entered
into a three-year $130 million syndicated bank revolving credit agreement (the
"Credit Agreement") to replace a $40 million revolving bank line of credit and
$15.6 million of long-term debt and to provide financing for future growth
opportunities. The maximum availability under the Credit Agreement was $130
million, including up to $15 million that could be used to support letters of
credit. On March 26, 1998, the Company amended the Credit Agreement to provide,
among other things, for borrowings of up to $180 million in the aggregate
outstanding at any time, including up to $15 million that could be used to
support letters of credit. At March 31, 1998, after the use of $54.1 million in
proceeds from the Notes Offering and $16.7 million of other available cash to
reduce the outstanding balance under the Credit Agreement, the Company had a
balance of $5.0 million in cash drawn under the Credit Agreement, and an
additional $11.6 million was being utilized to support the issuance of letters
of credit, primarily relating to insurance obligations.
 
     Borrowings under the Credit Agreement bear interest, at the Company's
option, at either (i) the Base Rate (defined as the administrative agent bank's
prime lending rate or 1/2 of 1% in excess of the federal funds rate) plus a
margin ranging from zero to .50%, or (ii) the Eurodollar Rate (equivalent to the
London Interbank Offered Rate) plus a margin ranging from 1% to 1.75% with the
Company's choice of a one-, two-, three-, or six-months interest period. The
applicable margin for each interest option depends on the Company's leverage
ratio for the fiscal quarter preceding the interest period; however, through
September 1998, the applicable Eurodollar margin shall not be less than 1.50%.
Based upon the Company's leverage ratio at March 31, 1998, the applicable
Eurodollar margin would have been 1.00%. The Credit Agreement will mature on
October 2, 2000 and is subject to one-year extensions at the discretion of the
Lenders. Notes issued under the Credit Agreement are prepayable at any time and
are due at expiration on October 2, 2000. The Credit Agreement imposes certain
financial covenants, including ones requiring the maintenance of a minimum net
worth, a minimum interest coverage ratio, a minimum fixed charge coverage ratio,
a maximum leverage ratio and a maximum debt-to-equity ratio. The Company is in
compliance with each of these covenants and has not been at risk of not being in
compliance. It also imposes certain other restrictions, including ones relating
to liens, other indebtedness, asset sales, investments, acquisitions or mergers
and the payment of dividends. The Credit Agreement is guaranteed on an unsecured
basis by substantially all of the Company's domestic subsidiaries. Advances
under the Credit Agreement are secured by a pledge of 66% of the capital stock
of certain of the Company's foreign subsidiaries. The Company incurred $0.5
million and $1.6 million of debt financing costs during the first quarter of
1998 and during 1997, respectively, in connection with the Credit Agreement,
which are being amortized over the term of the agreement.
 
     DA&S Acquisition Debt. In June 1997, the Company acquired all of the
outstanding capital stock of DA&S for $10.5 million, consisting of $10.1 million
of 9% long-term notes, the last of which are due in 2003, and $0.4 million in
cash. The total principal balance outstanding under these notes was $10.1
million as of March 31, 1998 and as of December 31, 1997. See Notes 3 and 6 of
Notes to Consolidated Financial Statements for further information.
 
     GPC Acquisition Debt. In June 1995, the Company acquired all of the
outstanding capital stock of GPC for approximately $18.8 million, consisting of
$11.5 million of 10% notes due in 2005, approximately $3.1 million in cash and
493,543 shares of the Company's common stock valued at $4.2 million. The
outstanding principal amount of such notes was reduced $4.0 million as of August
31, 1997 as a result of an August 1997 agreement between the sellers of GPC
("Sellers") and the Company that resolved certain issues that had arisen in
connection with the GPC purchase agreement. There was a corresponding $4.0
million increase in common stock, as the August 1997 agreement effectively
revalued the shares of the Company's common stock received by the Sellers in
connection with the June 1995 acquisition. The August 1997 agreement also
resulted
 
                                       65
<PAGE>   73
 
in a further reduction of $0.9 million, as of November 30, 1997, of the Sellers'
notes in satisfaction of a receivable from the Sellers of like amount. Due to
this reduction in principal amount, payment of these notes is now due to be
completed in 2002. The Company made scheduled principal payments of $0.6 million
in 1997 and $1.5 million in 1996 related to these notes. The total principal
balance outstanding under these notes was $4.5 million as of March 31, 1998 and
as of December 31, 1997. See Notes 3 and 6 of Notes to Consolidated Financial
Statements for further information.
 
DEBT RETIRED PRIOR TO AND CONCURRENT WITH THE NOTES OFFERING
 
     Sea Mar Debt.  In March 1998, the Company acquired all the outstanding
capital stock of Sea Mar for approximately $75.9 million in cash (including an
estimated $14.7 million in post closing purchase price adjustments) and
1,538,462 shares of the Company's common stock. The cash portion of this
transaction was financed with borrowings from the Notes Offering. At the time
this transaction was consummated, $15.7 million of Sea Mar debt was immediately
retired with a portion of the proceeds from the Notes Offering. See Notes 4 and
5 of Notes to Interim Condensed Consolidated Financial Statements for further
information.
 
     R&H Debt.  In October 1997, the Company acquired all of the outstanding
capital stock of Trey and certain associated operating assets for $31.3 million
in cash. At the time this transaction was consummated, $2.4 million of R&H debt
was retired, and $6.4 million was paid to certain key employees of R&H in
connection with incentive compensation arrangements. These transactions were
financed in part with borrowings under the Credit Agreement. See Note 3 of Notes
to Consolidated Financial Statements for further information.
 
     A.A. Debt.  In November 1997, the Company acquired all of the outstanding
capital stock of A.A. for $4.1 million in cash. This transaction was financed
with borrowings under the Credit Agreement. At the time this transaction was
consummated, $0.3 million of A.A. debt was immediately retired. See Note 3 of
Notes to Consolidated Financial Statements for further information.
 
     Antah Drilling Acquisition Debt.  In connection with the Antah Drilling
acquisition, the Company agreed to assume liability under Antah Drilling's term
loans, which aggregated $14.6 million at October 1996. In October 1997, the
remaining balance of $9.3 million was paid off with borrowings under the Credit
Agreement. The Company made scheduled principal payments of $3.9 million in 1997
and $1.4 million between October and December of 1996. See Notes 3 and 6 of
Notes to Consolidated Financial Statements for further information.
 
     Australia Rig 453 Debt.  In January 1996, the Company received $6.5 million
under a four-year term loan agreement (the "Australia Loan") in order to
refinance the construction costs incurred during 1995 to build Rig 453. The rig
construction costs were initially funded from the Company's cash resources and
borrowings under its then existing Credit Agreement. In October 1997, the
remaining balance of $3.5 million was paid off with borrowings under the Credit
Agreement. The Company made scheduled principal payments on the Australia Loan
of $1.2 million in 1997 and $1.8 million in 1996. See Note 6 of Notes to
Consolidated Financial Statements for further information.
 
     Pool Arctic Alaska Acquisition Debt.  The September 1994 Pool Arctic Alaska
acquisition was initially funded from the Company's cash resources and
approximately $6.7 million borrowed under the Company's then existing credit
agreement. In April 1995, the Company obtained a three-year term loan (the
"Alaska Loan") to refinance $10.0 million of the purchase price. In October
1997, the remaining balance of $2.7 million was paid off with borrowings under
the Credit Agreement. During 1997, 1996 and 1995, the Company made scheduled
principal payments of $1.9 million, $2.8 million and $2.6 million, respectively,
on the Alaska Loan. See Note 6 of Notes to Consolidated Financial Statements for
further information.
 
     DA&S Acquisition Debt.  As part of the DA&S acquisition, the Company
assumed $0.8 million of DA&S debt, all of which was immediately retired. See
Notes 3 and 6 of Notes to Consolidated Financial Statements for further
information.

     GPC Acquisition Debt.  As part of the GPC acquisition, the Company assumed
GPC's debt of $2.0 million, all of which was immediately retired. Also in
connection with the GPC acquisition, the Company assumed a liability for certain
deferred compensation obligations of GPC. To evidence such obligations, the
Company issued notes aggregating $1.5 million in principal amount to three
employees of GPC and made scheduled principal payments with respect to such
notes during 1997, 1996 and 1995 of $0.9 million, $0.4 million and $0.2 million,
respectively, and such notes were retired in 1997. See Note 6 of Notes to
Consolidated Financial Statements for further information.

                              DESCRIPTION OF NOTES
 
     The Old Notes were, and the New Notes will be issued pursuant to the
Indenture, a copy of which has been filed as an exhibit to this Registration
Statement. The following is a summary of the material terms and provisions of
the Old Notes and the New Notes (the "Notes"). The terms of the Notes include
those set forth in the Indenture and those made part of the Indenture by
reference to the Trust Indenture Act of 1939, as amended (the "Trust Indenture
Act"). The Notes are subject to all such terms, and holders of the Notes are
referred to the Indenture and the Trust Indenture Act for a statement thereof.
The following summary does not purport to be a complete description of the Notes
and is subject to the detailed provisions of, and qualified in its entirety by
reference to, the Indenture. Capitalized terms that are used but not otherwise
defined herein have the meanings assigned to them in the Indenture and such
definitions are incorporated herein by reference.
 
GENERAL
 
     On March 31, 1998, the Company issued $150 million aggregate principal
amount of Old Notes under the Indenture. The terms of the New Notes are
identical in all material respects to the Old Notes, except for certain transfer
restrictions and registration and other rights relating to the exchange of the
Old Notes for New Notes. Any Old Notes that remain outstanding after the
consummation of the Exchange Offer, together with the New Notes, will be treated
as a single class of securities under the Indenture.
 
     The Notes are senior subordinated unsecured obligations of the Company
limited to an aggregate principal amount of $150 million, subordinated in right
of payment to all existing and future Senior Indebtedness of the Company
(including the Company's obligations under the Credit Agreement) as described
below under "-- Subordination." The Notes are unconditionally guaranteed by each
Guarantor on a senior subordinated basis, with each such guarantee subordinated
to the Guarantor's guarantee of the obligations of the Company under the Credit
Agreement and to all other Senior Indebtedness of such Guarantor.
 
     The Notes bear interest at the rate shown on the cover page of this
Prospectus, payable on April 1 and October 1 of each year, commencing on October
1, 1998, to holders of record at the close of business on March 15 or September
15, as the case may be, immediately preceding the relevant interest payment
date. The Notes will mature on April 1, 2008 and will be issued in registered
form, without coupons, and in denominations of $1,000 and integral multiples
thereof. The Notes are payable as to principal, premium, if any, and interest at
the office or agency of the Company maintained for such purpose within the City
and State of New York or, at the option of the Company, by wire transfer of
immediately available funds or, in the case of certificated securities only, by
mailing a check to the registered address of the holder. See "-- Book-Entry,
Delivery and Form of Securities." Until otherwise designated by the Company, the
Company's office or agency in New York will be the office of the Trustee
maintained for such purpose.
 
     The interest rate on the Notes is subject to increase in certain
circumstances if the Company does not file a registration statement relating to
the registered Exchange Offer on a timely basis, if the registration statement
is not declared effective on a timely basis or if certain other conditions are
not satisfied. See "The Exchange Offer -- Purpose of the Exchange Offer." The
Old Notes and the New Notes will constitute a single series of debt securities
under the Indenture. If the Exchange Offer is consummated, holders of Old Notes
who do not exchange their Old Notes for New Notes will vote together with
holders of New Notes for all relevant purposes under the Indenture. In that
regard, the Indenture will require that certain actions by the holders thereof
(including acceleration following an Event of Default) must be taken, and
certain rights must be exercised, by specified minimum percentages of the
aggregate principal amount of the outstanding securities issued under the
Indenture. In determining whether holders of the requisite percentage in
principal amount have given any notice, consent or waiver or taken any other
action permitted under the Indenture, any Old Notes that remain outstanding
after the Exchange Offer will be aggregated with the New Notes, and the holders
of such Old Notes and the New Notes will vote together as a single series for
all such purposes. Accordingly, all references herein to specified percentages
in aggregate principal amount of the outstanding Notes shall be deemed to mean,
at any time after the Exchange Offer is consummated, such percentages in
aggregate principal amount of the Old Notes and the New Notes then outstanding.

SUBORDINATION
 
     The payment by the Company of principal of, and premium (if any) and
interest (including Special Interest) on the Notes, and by each Guarantor of
such amounts under its Note Guarantee (collectively, the "Note Indebtedness"),
will be subordinated to the prior payment in full in cash when due of the
principal of, and premium, if any, and accrued and unpaid interest on and all
other amounts owing in respect of, all existing and future Senior Indebtedness
of the Company and of each Guarantor, as the case may be. The Company has agreed
in the Indenture that it will not incur, directly or indirectly, any
Indebtedness that is subordinate or junior in ranking in right of payment to its
Senior Indebtedness unless such Indebtedness is pari passu with or is expressly
subordinated in right of payment to the Notes. In addition, each Guarantor has
agreed that it will not incur, directly or indirectly, any Indebtedness that is
subordinate or junior in ranking in right of payment to its Senior Indebtedness
unless such Indebtedness is pari passu with or is expressly subordinated in
right of payment to its Note Guarantee. As of March 31, 1998, the Company and
the Subsidiary Guarantors had outstanding approximately $19.5 million of
Indebtedness (excluding letters of credit, operating leases and other contingent
liabilities) other than the Notes, all of which constituted Senior Indebtedness.
Subject to certain limitations, the Company and its Subsidiaries (including the
Subsidiary Guarantors) may incur additional Indebtedness in the future. See
"-- Certain Covenants -- Limitations on Additional Indebtedness."
 
     The Indenture provides that, upon any payment or distribution to creditors
of the Company or any Guarantor of the assets of the Company or such Guarantor
of any kind or character in a total or partial liquidation or dissolution of the
Company or such Guarantor or in a bankruptcy, reorganization, insolvency,
receivership or similar proceeding relating to the Company or any Guarantor,
whether voluntary or involuntary (including any assignment for the benefit of
creditors and proceedings for marshaling of assets and liabilities of the
Company or any Guarantor), the holders of all Senior Indebtedness of the Company
or such Guarantor then outstanding will be entitled to payment in full in cash
(including interest accruing subsequent to the filing of petition of bankruptcy
or insolvency at the rate specified in the document relating to the applicable
Senior Indebtedness, whether or not such interest is an allowed claim
enforceable against the Company or such Guarantor under applicable law) before
the holders of Notes are entitled to receive any payment (other than payments
made from a trust previously established pursuant to provisions described under
"-- Satisfaction and Discharge of Indenture; Defeasance") on or with respect to
the Note Indebtedness and until all such Senior Indebtedness receives payment in
full in cash, any distribution to which the holders of Notes would be entitled
will be made to holders of such Senior Indebtedness.
 
     Upon the occurrence of any default in the payment of any principal of or
interest on or other amounts due on any Designated Senior Indebtedness of the
Company or any Guarantor (a "Payment Default"), no payment of any kind or
character shall be made by the Company or such Guarantor (or by any other Person
on its or their behalf) with respect to the Note Indebtedness unless and until
(i) such Payment Default shall have been cured or waived in accordance with the
instruments governing such Indebtedness or shall have ceased to exist, (ii) such
Designated Senior Indebtedness has been discharged or paid in full in cash in
accordance with the instruments governing such Indebtedness or (iii) the
benefits of this sentence have been waived by the holders of such Designated
Senior Indebtedness or their representative, including, if applicable, the
Agents, immediately after which the Company or any Guarantor, as the case may
be, must resume making any and all required payments, including missed payments,
in respect of its obligations under the Notes.
 
     Upon (1) the occurrence and continuance of an event of default (other than
a Payment Default) relating to Designated Senior Indebtedness, as such event of
default is defined therein or in the instrument or agreement under which it is
outstanding, which event of default, pursuant to the instruments governing such
Designated Senior Indebtedness, entitles the holders (or a specified portion of
the holders) of such Designated Senior Indebtedness or their designated
representative to immediately accelerate without further notice (except such
notice as may be required to effect such acceleration) the maturity of such
Designated Senior Indebtedness (whether or not such acceleration has actually
occurred) (a "Non-payment Default") and (2) the receipt by the Trustee and the
Company or any Guarantor from the trustee or other representative of holders of
such Designated Senior Indebtedness of written notice (a "Payment Blockage
Notice") of such occurrence, no payment is permitted to be made by the Company
or any Guarantor (or by any other Person on
                                       69
<PAGE>   77
 
its or their behalf) in respect of the Note Indebtedness for a period (a
"Payment Blockage Period") commencing on the date of receipt by the Trustee of
such notice and ending on the earliest to occur of the following events (subject
to any blockage of payments that may then be in effect due to a Payment Default
on Designated Senior Indebtedness): (w) such Non-payment Default has been cured
or waived or has ceased to exist; (x) a 179-consecutive-day period commencing on
the date such written notice is received by the Trustee has elapsed; (y) such
Payment Blockage Period has been terminated by written notice to the Trustee
from the trustee or other representative of holders of such Designated Senior
Indebtedness, whether or not such Non-payment Default has been cured or waived
or has ceased to exist; and (z) such Designated Senior Indebtedness has been
discharged or paid in full in cash, immediately after which, in the case of
clause (w), (x), (y) or (z), the Company or any Guarantor, as the case may be,
must resume making any and all required payments, including missed payments, in
respect of its obligations under the Notes. Notwithstanding the foregoing, (a)
not more than one Payment Blockage Period may be commenced in any period of 360
consecutive days and (b) no default or event of default with respect to the
Designated Senior Indebtedness of the Company or any Guarantor that was the
subject of a Payment Blockage Notice which existed or was continuing on the date
of the giving of any Payment Blockage Notice shall be or serve as the basis for
the giving of a subsequent Payment Blockage Notice whether or not within a
period of 360 consecutive days unless such default or event of default shall
have been cured or waived for a period of at least 90 consecutive days after
such date. Notwithstanding anything in the Indenture to the contrary, there must
be 180 consecutive days in any 360-day period in which no Payment Blockage
Period is in effect.
 
     Notwithstanding the foregoing, Noteholders may receive and retain Permitted
Junior Securities and payment from the money or the proceeds held in any
defeasance trust described under "-- Satisfaction and Discharge of Indenture;
Defeasance" below, and no such receipt or retention will be contractually
subordinated in right of payment to any Senior Indebtedness or subject to the
restrictions described in this "Subordination" section.
 
     In the event that, notwithstanding the foregoing, any payment or
distribution of assets of the Company or any Guarantor, whether in cash,
property or securities, shall be received by the Trustee or the holders of Notes
at a time when such payment or distribution is prohibited by this
"Subordination" section, such payment or distribution shall be segregated from
other funds or assets and held in trust for the benefit of the holders of Senior
Indebtedness of the Company or such Guarantor, as the case may be, and shall be
paid or delivered by the Trustee or such holders, as the case may be, to the
holders of the Senior Indebtedness of the Company or such Guarantor, as the case
may be, remaining unpaid or unprovided for or their representative or
representatives, or to the trustee or trustees under any indenture pursuant to
which any instruments evidencing any of such Senior Indebtedness of the Company
or such Guarantor, as the case may be, may have been issued, ratably according
to the aggregate amounts remaining unpaid on account of the Senior Indebtedness
of the Company or such Guarantor, as the case may be, held or represented by
each, for application to the payment of all Senior Indebtedness of the Company
or such Guarantor, as the case may be, remaining unpaid, to the extent necessary
to pay or to provide for the payment in full in cash of all such Senior
Indebtedness after giving effect to any concurrent payment or distribution to
the holders of such Senior Indebtedness.
 
     If the Company fails to make any payment on the Notes when due or within
any applicable grace period, whether or not such failure is on account of the
subordination provisions referred to above, such failure would constitute an
Event of Default under the Indenture and would enable the holders of Notes to
accelerate the maturity of the Notes. See "-- Events of Default."
 
     By reason of the subordination provisions contained in the Indenture, in
the event of bankruptcy, liquidation, insolvency or other similar proceedings,
creditors of the Company who are holders of Senior Indebtedness may recover
more, ratably, than the holders of the Notes, and creditors of the Company who
are not holders of Senior Indebtedness may recover less, ratably, than holders
of Senior Indebtedness and may recover more, ratably, than the holders of the
Notes.

GUARANTEES
 
     The Company's payment obligations under the Notes are jointly and severally
guaranteed by each Subsidiary Guarantor. Each Note Guarantee is an unsecured
senior subordinated obligation of the Subsidiary Guarantor providing it, and
such Note Guarantee ranks junior in right of payment to all existing and future
Senior Indebtedness of such Guarantor, including such Guarantor's guarantee of
the Company's obligations under the Credit Agreement. The obligations of each
Subsidiary Guarantor under its Note Guarantee is limited so as not to constitute
a fraudulent conveyance under applicable law.
 
     The Indenture provides that no Subsidiary Guarantor may consolidate with or
merge with or into (whether or not such Subsidiary Guarantor is the surviving
Person) another Person whether or not affiliated with such Subsidiary Guarantor
unless (i) subject to the provisions of the following paragraph, the Person
formed by or surviving any such consolidation or merger (if other than such
Subsidiary Guarantor) assumes all of the obligations of such Subsidiary
Guarantor pursuant to a supplemental indenture, in form and substance
satisfactory to the Trustee, under the Notes and the Indenture; (ii) immediately
after giving effect to such transaction, no Default or Event of Default exists;
and (iii) immediately after giving effect to such transaction, the Coverage
Ratio Incurrence Condition would be met.
 
     The Indenture provides that in the event of a sale or other disposition of
all or substantially all of the assets of a Subsidiary Guarantor to a third
party or an Unrestricted Subsidiary in a transaction that does not violate any
of the covenants in the Indenture, by way of merger, consolidation or otherwise,
or a sale or other disposition of all of the Capital Stock of a Subsidiary
Guarantor, then such Subsidiary Guarantor (in the event of a sale or other
disposition, by way of such a merger, consolidation or otherwise, of all of the
Capital Stock of such Subsidiary Guarantor) or the Person acquiring the property
(in the event of a sale or other disposition of all or substantially all of the
assets of such Subsidiary Guarantor) will be released from and relieved of any
obligations under its Note Guarantee; provided that the Net Available Proceeds
of such sale or other disposition are applied in accordance with the covenant
described under the caption "-- Certain Covenants -- Limitations on Asset
Sales."
 
     Any Subsidiary Guarantor that is designated an Unrestricted Subsidiary in
accordance with the terms of the Indenture shall be released and relieved of its
obligations under its Note Guarantee and any Unrestricted Subsidiary and any
newly formed or newly acquired Subsidiary that becomes a Restricted Subsidiary
will be required to execute a supplement to the Indenture in accordance with the
terms of the Indenture.
 
OPTIONAL REDEMPTION OF THE NOTES
 
     The Notes may not be redeemed prior to April 1, 2003, but will be
redeemable at the option of the Company, in whole or in part, at any time on or
after April 1, 2003, at the following redemption prices (expressed as
percentages of principal amount), together with accrued and unpaid interest, if
any, thereon to the redemption date, if redeemed during the twelve-month period
beginning on April 1 of the year indicated below:

2006 and thereafter...............................   100.000%
</TABLE>
 
     Notwithstanding the foregoing, from time to time prior to April 1, 2001,
the Company may redeem up to 35% of the aggregate principal amount of the Notes
outstanding on the Issue Date with the net cash proceeds of one or more Equity
Offerings at a redemption price equal to 108.625% of the principal amount
thereof, plus accrued and unpaid interest and Special Interest, if any, to the
redemption date; provided that (a) at least $97.5 million of the aggregate
principal amount of the Notes remains outstanding immediately after the
 
                                       71
<PAGE>   79
 
occurrence of any such redemption and (b) each such redemption occurs within 60
days of the date of the closing of any such Equity Offering.
 
     If less than all of the Notes are to be redeemed at any time, selection of
the Notes to be redeemed will be made by the Trustee from among the outstanding
Notes on a pro rata basis, by lot or by any other method permitted in the
Indenture. Notice of redemption will be mailed at least 30 days but not more
than 60 days before the redemption date to each holder whose Notes are to be
redeemed at the registered address of such holder. On and after the redemption
date, interest will cease to accrue on the Notes or portions thereof called for
redemption.
 
CHANGE OF CONTROL
 
     Upon the occurrence of a Change of Control, each holder of the Notes will
have the right to require that the Company repurchase such holder's Notes for a
cash price (the "Change of Control Purchase Price") equal to 101% of the
principal amount of the Notes, plus accrued and unpaid interest and Special
Interest, if any, to the date of repurchase, all in accordance with the
following paragraph.
 
     Within 30 days following any Change of Control, the Company will mail to
the Trustee (who shall mail to each holder) a notice (i) describing the
transaction or transactions that constitute the Change of Control, (ii) offering
to repurchase, pursuant to the procedures required by the Indenture and
described in such notice (a "Change of Control Offer"), on a date specified in
such notice (which shall be a business day not earlier than 30 days or later
than 60 days from the date such notice is mailed) and for the Change of Control
Purchase Price, all Notes properly tendered by such holder pursuant to such
offer to purchase for the Change of Control Purchase Price and (iii) describing
the procedures that holders must follow to accept the Change of Control Offer.
The Change of Control Offer is required to remain open for at least 20 business
days or for such longer period as is required by law.
 
     The occurrence of the events constituting a Change of Control under the
Indenture may result in an event of default in respect of other Indebtedness
(including the Senior Indebtedness) of the Company and its Subsidiaries and,
consequently, the lenders thereof may have the right to require repayment of
such Indebtedness in full. If a Change of Control Offer is made, there can be no
assurance that the Company will have available funds sufficient to pay for all
or any of the Notes that might be delivered by holders of Notes seeking to
accept the Change of Control Offer. There can be no assurance that in the event
of a Change of Control the Company will be able to obtain the consents necessary
to consummate a Change of Control Offer from the lenders under agreements
governing outstanding Indebtedness which may prohibit such an offer. The
Company's obligation to make a Change of Control Offer will be satisfied if a
third party makes the Change of Control Offer in the manner and at the times and
otherwise in compliance with the requirements applicable to a Change of Control
Offer made by the Company and purchases all Notes properly tendered and not
withdrawn under such Change of Control Offer. The definition of Change of
Control includes the sale of "all or substantially all" of the assets of the
Company and its Subsidiaries, in either case taken as a whole, the determination
of which depends upon the circumstances of any such sale and is subject to
interpretation under applicable legal precedent.
 
     The Change of Control feature of the Notes, by requiring a Change of
Control Offer, may in certain circumstances make more difficult or discourage a
sale or takeover of the Company, and, thus, the removal of incumbent management.
The Change of Control feature, however, is not part of a plan by management to
adopt a series of antitakeover provisions. Instead, the Change of Control
feature is a result of negotiations between the Company and the Initial
Purchasers. Subject to the limitations discussed below, the Company could, in
the future, enter into certain transactions, including acquisitions,
refinancings or other recapitalizations, that would not constitute a Change of
Control under the Indenture, but that could increase the amount of Indebtedness
outstanding at such time or otherwise affect the Company's capital structure or
credit ratings.
 
     The Company will comply with the applicable tender offer rules, including
the requirements of Rule 14e-1 under the Exchange Act and any other applicable
laws and regulations in connection with the purchase of Notes pursuant to a
Change of Control Offer.

CERTAIN COVENANTS
 
     Limitations on Additional Indebtedness.  The Indenture provides that the
Company will not, and will not permit any of its Restricted Subsidiaries to,
directly or indirectly, incur any Indebtedness (including without limitation
Acquired Indebtedness); provided that the Company and its Restricted
Subsidiaries may incur Permitted Indebtedness and may incur additional
Indebtedness if, after giving effect thereto, the Company's Consolidated
Interest Coverage Ratio on the date thereof would be at least 2.5 to 1,
determined on a pro forma basis as if the incurrence of such additional
Indebtedness, and the application of the net proceeds therefrom, had occurred at
the beginning of the four-quarter period used to calculate the Company's
Consolidated Interest Coverage Ratio.
 
     Limitation on the Issuance of Capital Stock of Restricted
Subsidiaries.  The Indenture provides that the Company will not permit any
Restricted Subsidiary, directly or indirectly, to issue or sell any shares of
its Capital Stock (including options, warrants or other rights to purchase
shares of such Capital Stock) except (i) to the Company or a Wholly-Owned
Restricted Subsidiary, (ii) if, immediately after giving effect to such issuance
or sale, such Restricted Subsidiary would no longer constitute a Restricted
Subsidiary or (iii) to the extent such shares represent directors' qualifying
shares or shares required by applicable law to be held by a Person other than
the Company or a Wholly-Owned Restricted Subsidiary. The proceeds of any sale of
Capital Stock permitted hereunder and referred to in clauses (ii) and (iii)
above will be treated as Net Available Proceeds and must be applied in a manner
consistent with the provisions of the covenant described under "-- Limitations
on Asset Sales".
 
     Limitations on Layering Debt.  The Indenture provides that the Company will
not, and will not permit any Subsidiary Guarantor to, incur any Indebtedness
that is subordinate or junior in right of payment to any Senior Indebtedness of
the Company or such Subsidiary Guarantor unless such Indebtedness by its terms
is pari passu with, or subordinated to, the Notes or the Note Guarantee of such
Subsidiary Guarantor, as the case may be.
 
     Limitations on Restricted Payments.  The Indenture provides that the
Company will not, and will not permit any of its Restricted Subsidiaries to,
directly or indirectly, make any Restricted Payment (except as permitted below)
if at the time of such Restricted Payment:
 
          (i) a Default or Event of Default shall have occurred and be
     continuing or shall occur as a consequence thereof;
 
          (ii) the Company would be unable to meet the Coverage Ratio Incurrence
     Condition; or
 
          (iii) the amount of such Restricted Payment, when added to the
     aggregate amount of all other Restricted Payments (except as expressly
     provided in the second following paragraph) made after the Issue Date,
     exceeds the sum of (A) 50% of the Company's Consolidated Net Income (taken
     as one accounting period) from the beginning of the first fiscal quarter
     commencing after the Issue Date to the end of the Company's most recently
     ended fiscal quarter for which financial statements are available at the
     time of such Restricted Payment (or, if such aggregate Consolidated Net
     Income shall be a deficit, minus 100% of such aggregate deficit) plus (B)
     the net cash proceeds from the issuance and sale (other than to a
     Subsidiary of the Company) after the Issue Date of (1) the Company's
     Capital Stock that is not Disqualified Capital Stock or (2) debt securities
     of the Company that have been converted into the Company's Capital Stock
     that is not Disqualified Capital Stock (and is not then held by a
     Subsidiary of the Company), plus (C) to the extent that any Restricted
     Investment that was made after the Issue Date is sold for cash or otherwise
     liquidated or repaid for cash, the lesser of (x) the cash return of capital
     with respect to such Restricted Investment (less the cost of disposition,
     if any) and (y) the initial amount of such Restricted Investment plus (D)
     the amount of Restricted Investment outstanding in an Unrestricted
     Subsidiary at the time such Unrestricted Subsidiary is designated a
     Restricted Subsidiary of the Company in accordance with the definition of
     "Unrestricted Subsidiary" plus (E) $5 million.
 
     The foregoing provisions do not prohibit (1) the payment of any dividend by
the Company or any Restricted Subsidiary within 60 days after the date of
declaration thereof, if at said date of declaration such
 
                                       73
<PAGE>   81
 
payment would have complied with the provisions of the Indenture; (2) the
redemption, repurchase, retirement or other acquisition of any Capital Stock of
the Company in exchange for, or out of the proceeds of, the substantially
concurrent sale (other than to a Subsidiary of the Company) of other Capital
Stock of the Company (other than any Disqualified Capital Stock); (3) the
defeasance, redemption, repurchase or other retirement of Subordinated
Indebtedness in exchange for, or out of the proceeds of, the substantially
concurrent issue and sale of Capital Stock of the Company (other than (x)
Disqualified Capital Stock, (y) Capital Stock sold to a Subsidiary of the
Company and (z) Capital Stock purchased with the proceeds of loans from the
Company or any of its Subsidiaries); (4) the making of a Related Business
Investment in joint ventures or Unrestricted Subsidiaries out of the proceeds of
the substantially concurrent issue and sale of Capital Stock of the Company
(other than (x) Disqualified Capital Stock, (y) Capital Stock sold to a
Subsidiary of the Company and (z) Capital Stock purchased with the proceeds of
loans from the Company or any of its Subsidiaries); (5) the repurchase,
redemption or other acquisition or retirement for value of any Capital Stock
held by any member of the Company's management pursuant to any management equity
subscription agreement, employment agreement, stock option agreement or other
compensation agreement in an amount not to exceed $500,000 in the aggregate in
any fiscal year of the Company; or (6) Restricted Investments the amount of
which, together with the amount of all other Restricted Investments made
pursuant to this clause (6) after the Issue Date, does not exceed $20 million,
provided that, in the case of clause (6), no Default or Event of Default shall
have occurred and be continuing or occur as a consequence of the actions or
payments set forth therein.
 
     The Restricted Payment permitted pursuant to clause (1) of the preceding
paragraph shall be included once in calculating whether the conditions of clause
(iii) of the second preceding paragraph have been met with respect to any
subsequent Restricted Payments. For purposes of determining compliance with this
"Limitation on Restricted Payments" covenant, in the event that a transaction
meets the criteria of more than one of the types of Restricted Payments
described in the clauses of the immediately preceding paragraph or of the
clauses of the definition of "Restricted Payment," the Company, in its sole
discretion, shall classify such transaction and only be required to include the
amount and type of such transaction in one of such clauses. If an issuance of
Capital Stock of the Company is applied to make a Restricted Payment pursuant to
clause (2), (3) or (4) above, then, in calculating whether the conditions of
clause (iii) of the second preceding paragraph have been met with respect to any
subsequent Restricted Payments, the proceeds of any such issuance shall be
included under such clause (iii) only to the extent such proceeds are not
applied as so described in this sentence. In addition, Restricted Investments
made pursuant to clause (6) of the preceding paragraph shall not be treated as a
Restricted Payment or Restricted Investment for purposes of calculating whether
the conditions of clause (iii) of the second preceding paragraph have been met
with respect to any subsequent Restricted Payments.
 
     Not later than the date of making any Restricted Payment, the Company shall
deliver to the Trustee an Officers' Certificate stating that such Restricted
Payment is permitted and setting forth the basis upon which the calculations
required by the covenant "Limitations on Restricted Payments" were computed,
which calculations shall be based upon the Company's latest available financial
statements.
 
     Limitations on Restrictions on Distributions from Restricted
Subsidiaries.  The Indenture provides that the Company will not, and will not
permit any of its Restricted Subsidiaries to, create or otherwise cause or
suffer to exist or become effective any consensual Payment Restriction with
respect to any of its Restricted Subsidiaries, except for (a) any such Payment
Restriction in effect on the Issue Date under the Credit Agreement or any
similar Payment Restriction under any similar credit facility, or any amendment,
restatement, renewal, replacement or refinancing of any of the foregoing,
provided that such similar Payment Restrictions are not, taken as a whole,
materially more restrictive than the Payment Restrictions in effect on the Issue
Date under the Credit Agreement, (b) any such Payment Restriction in effect on
the Issue Date consisting of customary net worth or leverage tests in effect on
the Issue Date under any credit facility of any Foreign Subsidiary, or any
amendment, restatement, renewal, replacement or refinancing of any of the
foregoing (including for purposes of this clause (b), any increase in the
principal amount available thereunder) (a "Replacement Facility"), provided that
such Payment Restrictions in any such Replacement Facility are not, taken as a
whole, materially more restrictive than the Payment Restrictions in effect on
the
 
                                       74
<PAGE>   82
 
Issue Date under the facility amended, restated, renewed, replaced or
refinanced, (c) any such Payment Restriction under any agreement evidencing any
Acquired Indebtedness that was permitted to be incurred pursuant to the
Indenture in effect at the time of such incurrence and not created in
contemplation of such event, provided that such Payment Restriction is not
extended to apply to any of the assets of the entities not previously subject
thereto, (d) any such Payment Restriction arising in connection with Refinancing
Indebtedness, provided that any such Payment Restrictions that arise under such
Refinancing Indebtedness are not, taken as a whole, materially more restrictive
than those under the agreement creating or evidencing the Indebtedness being
refunded or refinanced and (e) any such restriction by reason of customary
provisions restricting assignments, subletting or other transfers contained in
leases, licenses and similar agreements entered into in the ordinary course of
business.
 
     Limitations on Transactions with Affiliates.  The Indenture provides that
the Company will not, and will not permit any of its Restricted Subsidiaries to,
directly or indirectly, in one transaction or a series of related transactions,
sell, lease, transfer or otherwise dispose of any of its properties or assets
to, or purchase any property or assets from or enter into any contract,
agreement, understanding, loan, advance or guarantee with, or for the benefit
of, any Affiliate (each of the foregoing, an "Affiliate Transaction"), unless
(i) such Affiliate Transaction is on terms that are no less favorable to the
Company or the relevant Restricted Subsidiary than those that would have been
obtained in a comparable transaction by the Company or such Restricted
Subsidiary with an unrelated Person and (ii) the Company delivers to the Trustee
(a) with respect to any Affiliate Transaction (or series of related
transactions) involving aggregate payments in excess of $5 million, an Officers'
Certificate certifying that such Affiliate Transaction complies with clause (i)
above and a Secretary's Certificate which sets forth and authenticates a
resolution that has been adopted by a vote of a majority of the Independent
Directors approving such Affiliate Transaction or, if at the time fewer than
three Independent Directors are then in office, a Secretary's Certificate which
sets forth and authenticates a resolution that has been adopted unanimously by
the Company's Board of Directors and (b) with respect to any Affiliate
Transaction (or series of related transactions) involving aggregate payments of
$15 million or more, the certificates described in the preceding clause (a) and
an opinion as to the fairness to the Company or such Subsidiary from a financial
point of view issued by an Independent Financial Advisor; provided, however,
that the following shall not be deemed to be Affiliate Transactions: (i)
transactions exclusively between or among (1) the Company and one or more
Restricted Subsidiaries or (2) Restricted Subsidiaries, provided, in each case,
that no Affiliate of the Company (other than another Restricted Subsidiary) owns
Capital Stock of any such Restricted Subsidiary; (ii) transactions between the
Company or any Restricted Subsidiary and any qualified employee stock ownership
plan established for the benefit of the Company's employees, or the
establishment or maintenance of any such plan; (iii) reasonable director,
officer and employee compensation and other benefits, and indemnification
arrangements approved by a majority of the Independent Directors on the Board of
Directors; (iv) transactions permitted by the "Limitations on Restricted
Payments" covenant; (v) the pledge of Capital Stock of Unrestricted Subsidiaries
to support the Indebtedness thereof; (vi) transactions between the Company and
any Restricted Subsidiary and Kuukpik/ Pool Arctic Alaska, an Alaskan
partnership ("KPAA"), so long as no direct or indirect holder of an equity
interest in KPAA (other than the Company or a Restricted Subsidiary) is an
Affiliate of the Company or a Restricted Subsidiary and provided that at the
time of such transaction the Company and its Restricted Subsidiaries have no
less economic benefit in KPAA than the Company and its Restricted Subsidiaries
had as of the Issue Date; (vii) transactions between the Company or any
Restricted Subsidiary and any Affiliate of the Company or such Restricted
Subsidiary that is a joint venture, provided that no direct or indirect holder
of an equity interest in such joint venture (other than the Company or a
Restricted Subsidiary) is an Affiliate of the Company or such Restricted
Subsidiary; and (viii) sale of inventory in the ordinary course of business from
the Company or any Restricted Subsidiary to any Affiliate of the Company.
 
     Limitations on Liens.  The Company shall not, and shall not permit any
Restricted Subsidiary to, directly or indirectly, incur or permit to exist any
Lien of any nature whatsoever on any property of the Company or any Restricted
Subsidiary (including Capital Stock of a Restricted Subsidiary), whether owned
at the Issue Date or thereafter acquired, which secures Indebtedness that is not
Senior Indebtedness, except Permitted Liens, unless contemporaneously therewith
effective provision is made to secure the Notes or its
 
                                       75
<PAGE>   83
 
Note Guarantee, as the case may be, equally and ratably with (or if such Lien
secures Subordinated Indebtedness, prior to) such Indebtedness.
 
     Limitations on Asset Sales.  (a) The Indenture provides that the Company
will not, and will not permit any of its Restricted Subsidiaries to, consummate
any Asset Sale unless (i) the Company or such Restricted Subsidiary receives
consideration at the time of such Asset Sale at least equal to the Fair Market
Value of the assets included in such Asset Sale (evidenced by the delivery by
the Company to the Trustee of an Officers' Certificate certifying that such
Asset Sale complies with this clause (i)), (ii) immediately before and
immediately giving effect to such Asset Sale, no Default or Event of Default
shall have occurred and be continuing, and (iii) at least 75% of the
consideration received by the Company or such Restricted Subsidiary therefor is
in the form of cash paid at the closing thereof. The amount (without
duplication) of any (x) Indebtedness (other than Subordinated Indebtedness) of
the Company or such Restricted Subsidiary that is expressly assumed by the
transferee in such Asset Sale and with respect to which the Company or such
Restricted Subsidiary, as the case may be, is unconditionally released by the
holder of such Indebtedness, and (y) any Cash Equivalents, or other notes,
securities or items of property received from such transferee that are promptly
(but in any event within 30 days) converted by the Company or such Restricted
Subsidiary to cash (to the extent of the cash actually so received), shall be
deemed to be cash for purposes of clause (ii) and, in the case of clause (x)
above, shall also be deemed to constitute a repayment of, and a permanent
reduction in, the amount of such Indebtedness for purposes of the following
paragraph (b). If at any time any non-cash consideration received by the Company
or any Restricted Subsidiary of the Company, as the case may be, in connection
with any Asset Sale is converted into or sold or otherwise disposed of for cash
(other than interest received with respect to any such non-cash consideration),
then the date of such conversion or disposition shall be deemed to constitute
the date of an Asset Sale hereunder and the Net Available Proceeds thereof shall
be applied in accordance with this covenant. A transfer of assets by the Company
to a Restricted Subsidiary or by a Restricted Subsidiary to the Company or to a
Restricted Subsidiary will not be deemed to be an Asset Sale and a transfer of
assets that constitutes a Restricted Investment and that is permitted under
"-- Limitations on Restricted Payments" will not be deemed to be an Asset Sale.
 
     (b) If the Company or any Restricted Subsidiary engages in an Asset Sale,
the Company or any Restricted Subsidiary shall either, no later than 270 days
after such Asset Sale, (i) apply all or any of the Net Available Proceeds
therefrom to repay amounts outstanding under the Credit Agreement or any other
Senior Indebtedness; provided, in each case, that the related loan commitment
(if any) is thereby permanently reduced by the amount of such Indebtedness so
repaid and/or (ii) invest all or any part of the Net Available Proceeds thereof
in the purchase of fixed assets to be used by the Company and its Restricted
Subsidiaries in a Related Business (together with any short-term assets
incidental thereto), or the making of a Related Business Investment. The amount
of such Net Available Proceeds not applied or invested as provided in this
paragraph will constitute "Excess Proceeds."
 
     (c) When the aggregate amount of Excess Proceeds equals or exceed $10
million, the Company will be required to make an offer to purchase, from all
holders of the Notes, an aggregate principal amount of Notes equal to the amount
of such Excess Proceeds as follows:
 
          (i) The Company will make an offer to purchase (a "Net Proceeds
     Offer") from all holders of the Notes in accordance with the procedures set
     forth in the Indenture the maximum principal amount (expressed as a
     multiple of $1,000) of Notes that may be purchased out of the amount (the
     "Payment Amount") of such Excess Proceeds.
 
          (ii) The offer price for the Notes will be payable in cash in an
     amount equal to 100% of the principal amount of the Notes tendered pursuant
     to a Net Proceeds Offer, plus accrued and unpaid interest and Special
     Interest, if any, to the date such Net Proceeds Offer is consummated (the
     "Offered Price"), in accordance with the procedures set forth in the
     Indenture. To the extent that the aggregate Offered Price of Notes tendered
     pursuant to a Net Proceeds Offer is less than the Payment Amount relating
     thereto (such shortfall constituting a "Net Proceeds Deficiency"), the
     Company may use such Net Proceeds Deficiency, or a portion thereof, for
     general corporate purposes, subject to the limitations of the "Limitations
     on Restricted Payments" covenant.
 
                                       76
<PAGE>   84
 
          (iii) If the aggregate Offered Price of Notes validly tendered and not
     withdrawn by holders thereof exceeds the Payment Amount, Notes to be
     purchased will be selected on a pro rata basis.
 
          (iv) Upon completion of such Net Proceeds Offer in accordance with the
     foregoing provisions, the amount of Excess Proceeds with respect to which
     such Net Proceeds Offer was made shall be deemed to be zero.
 
     The Company will not permit any Subsidiary to enter into or suffer to exist
any agreement that would place any restriction of any kind (other than pursuant
to law or regulation) on the ability of the Company to make a Net Proceeds Offer
following any Asset Sale. The Company will comply with Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder, if
applicable, in the event that an Asset Sale occurs and the Company is required
to purchase Notes as described above.
 
     Limitations on Mergers and Certain Other Transactions.  The Indenture
provides that the Company will not, in a single transaction or a series of
related transactions, (i) consolidate or merge with or into (other than a merger
with a Wholly-Owned Restricted Subsidiary solely for the purpose of changing the
Company's jurisdiction of incorporation to another State of the United States),
or sell, lease, transfer, convey or otherwise dispose of or assign all or
substantially all of the assets of the Company or the Company and its
Subsidiaries (taken as a whole), or assign any of its obligations under the
Notes and the Indenture, to any Person or (ii) adopt a Plan of Liquidation
unless, in either case: (a) the Person formed by or surviving such consolidation
or merger (if other than the Company) or to which such sale, lease, conveyance
or other disposition or assignment shall be made (or, in the case of a Plan of
Liquidation, any Person to which assets are transferred) (collectively, the
"Successor"), is a corporation organized and existing under the laws of any
State of the United States of America or the District of Columbia, and the
Successor assumes by supplemental indenture in a form satisfactory to the
Trustee all of the obligations of the Company under the Notes and the Indenture;
(b) immediately prior to and immediately after giving effect to such transaction
and the assumption of the obligations as set forth in clause (a) above and the
incurrence of any Indebtedness to be incurred in connection therewith, no
Default or Event of Default shall have occurred and be continuing; and (c)
immediately after and giving effect to such transaction and the assumption of
the obligations set forth in clause (a) above and the incurrence of any
Indebtedness to be incurred in connection therewith, and the use of any net
proceeds therefrom on a pro forma basis, (1) the Consolidated Net Worth of the
Company or the Successor, as the case may be, would be at least equal to the
Consolidated Net Worth of the Company immediately prior to such transaction and
(2) the Company or the Successor, as the case may be, could meet the Coverage
Ratio Incurrence Condition; and (d) each Subsidiary Guarantor, unless it is the
other party to the transactions described above, shall have by supplemental
indenture confirmed that its Note Guarantee shall apply to the obligations of
the Company or the Successor under the Notes and the Indenture. For purposes of
this covenant, any Indebtedness of the Successor which was not Indebtedness of
the Company immediately prior to the transaction shall be deemed to have been
incurred in connection with such transaction.
 
     Additional Note Guarantees.  The Indenture provides that if the Company or
any of its Subsidiaries shall acquire or create another Subsidiary (other than
(x) any Foreign Subsidiary or (y) a Subsidiary that has been designated as an
Unrestricted Subsidiary), then such newly acquired or created Subsidiary will be
required to execute a Note Guarantee, in accordance with the terms of the
Indenture.
 
     Reports.  Whether or not required by the rules and regulations of the
Commission, so long as any Notes are outstanding, the Company and the Subsidiary
Guarantors will file with the Commission, to the extent such filings are
accepted by the Commission, and will furnish to the Trustee and holders of Notes
all quarterly and annual reports and other information, documents and reports
that would be required to be filed with the Commission pursuant to Section 13 of
the Exchange Act if the Company and the Subsidiary Guarantors were required to
file under such section. In addition, the Company and the Subsidiary Guarantors
will make such information available to prospective purchasers of the Notes,
securities analysts and broker-dealers who request it in writing. The Company
and the Subsidiary Guarantors have agreed that, for so long as any Notes remain
outstanding, they will furnish to the holders and beneficial holders of Notes
and to prospective purchasers of Notes designated by the holders to broker
dealers, upon their request, the information required to be delivered pursuant
to Rule 144A(d)(4) under the Securities Act.

EVENTS OF DEFAULT
 
     An "Event of Default" is defined in the Indenture as (i) failure by the
Company to pay interest on any of the Notes when it becomes due and payable and
the continuance of any such failure for 30 days; (ii) failure by the Company to
pay the principal or premium, if any, on any of the Notes when it becomes due
and payable, whether at stated maturity, upon redemption, upon acceleration or
otherwise; (iii) failure by the Company to comply with any of its agreements or
covenants described above under "Certain Covenants -- Limitations on Mergers and
Certain Other Transactions", or in respect of its obligations to make a Change
of Control Offer or a Net Proceeds Offer described in "Change of Control" and
"Certain Covenants -- Limitations on Asset Sales", respectively; (iv) failure by
the Company to comply with any other covenant in the Indenture and continuance
of such failure for 60 days after notice of such failure has been given to the
Company by the Trustee or by the holders of at least 25% of the aggregate
principal amount of the Notes then outstanding; (v) failure by either the
Company or any of its Restricted Subsidiaries to make any payment when due after
the expiration of any applicable grace period, in respect of any Indebtedness of
the Company or any of such Restricted Subsidiaries, or the acceleration of the
maturity of such Indebtedness by the holders thereof because of a default, with
an aggregate outstanding principal amount for all such Indebtedness under this
clause (v) of $10 million or more; (vi) one or more final, non-appealable
judgments or orders that exceed $10 million in the aggregate for the payment of
money have been entered by a court or courts of competent jurisdiction against
the Company or any Subsidiary of the Company and such judgment or judgments have
not been satisfied, stayed, annulled or rescinded within 60 days of being
entered; (vii) certain events of bankruptcy, insolvency or reorganization
involving the Company or any Significant Subsidiary; and (viii) except as
permitted by the Indenture, any Note Guarantee ceases to be in full force and
effect or any Guarantor repudiates its obligations under any Note Guarantee.
 
     If an Event of Default (other than an Event of Default specified in clause
(vii) above involving the Company), shall have occurred and be continuing under
the Indenture, the Trustee, by written notice to the Company, or the holders of
at least 25% in aggregate principal amount of the Notes then outstanding by
written notice to the Company and the Trustee may declare all amounts owing
under the Notes to be due and payable immediately. Upon such declaration of
acceleration, the aggregate principal of, premium, if any, and interest on the
outstanding Notes shall immediately become due and payable. If an Event of
Default results from bankruptcy, insolvency or reorganization involving the
Company, all outstanding Notes shall become due and payable without any further
action or notice. In certain cases, the holders of a majority in aggregate
principal amount of the Notes then outstanding may waive an existing Default or
Event of Default and its consequences, except a default in the payment of
principal of, premium, if any, and interest on the Notes.
 
     The holders may not enforce the provisions of the Indenture or the Notes
except as provided in the Indenture. Subject to certain limitations, holders of
a majority in principal amount of the Notes then outstanding may direct the
Trustee in its exercise of any trust or power; provided however, that such
direction does not conflict with the terms of the Indenture. The Trustee may
withhold from the holders notice of any continuing Default or Event of Default
(except any Default or Event of Default in payment of principal of, premium, if
any, or interest on the Notes) if the Trustee determines that withholding such
notice is in the holders' interest.
 
     The Company is required to deliver to the Trustee annually a statement
regarding compliance with the Indenture and, upon any Officer of the Company
becoming aware of any Default or Event of Default, a statement specifying such
Default or Event of Default and what action the Company is taking or proposes to
take with respect thereto.
 
SATISFACTION AND DISCHARGE OF INDENTURE; DEFEASANCE
 
     The Company may terminate its obligations under the Indenture at any time
by delivering all outstanding Notes to the Trustee for cancellation and paying
all sums payable by it thereunder. The Company, at its option, (i) will be
discharged from any and all obligations with respect to the Notes (except for
certain obligations of the Company to register the transfer or exchange of such
Notes, replace stolen, lost or mutilated Notes, maintain paying agencies and
hold moneys for payment in trust); or (ii) need not comply with certain
 
                                       78
<PAGE>   86
 
of the restrictive covenants with respect to the Indenture, if the Company
deposits with the Trustee, in trust, U.S. Legal Tender or non-callable
Government Securities or a combination thereof that, through the payment of
interest and premium thereon and principal amount at maturity in respect thereof
in accordance with their terms, will be sufficient to pay all the principal
amount at maturity of and interest and premium on the Notes on the dates such
payments are due in accordance with the terms of such Notes as well as the
Trustee's fees and expenses. To exercise either such option, the Company is
required to deliver to the Trustee (A) an Opinion of Counsel and, in connection
with a discharge pursuant to clause (i) above, confirmation of such counsel that
(I) the Company has received from, or there has been published by, the Internal
Revenue Service a ruling or (II) since the date of the Indenture there has been
a change in the applicable federal income tax law, in either case to the effect
that the holders of the Notes will not recognize income, gain or loss for
federal income tax purposes as a result of the deposit and related defeasance
and will be subject to federal income tax on the same amount and in the same
manner and at the same times as would have been the case if such option had not
been exercised, (B) subject to certain qualifications, an Opinion of Counsel to
the effect that funds so deposited will not violate the Investment Company Act
of 1940 and will not be subject to the effect of Section 547 of the United
States Bankruptcy Code or Section 15 of the New York Debtor and Creditor Law and
(C) an Officers' Certificate and an Opinion of Counsel to the effect that the
Company has complied with all conditions precedent to the defeasance.
 
TRANSFER AND EXCHANGE
 
     A holder will be able to register the transfer of or exchange Notes only in
accordance with the provisions of the Indenture. The Registrar may require a
holder, among other things, to furnish appropriate endorsements and transfer
documents and to pay any taxes and fees required by law or permitted by the
Indenture. Without the prior consent of the Company, neither the Trustee nor the
Registrar is required (i) to register the transfer of or exchange any Note
selected for redemption, (ii) to register the transfer of or exchange any Note
for a period of 15 days before a selection of Notes to be redeemed or (iii) to
register the transfer or exchange of a Note between a record date and the next
succeeding interest payment date. The registered holder of a Note will be
treated as the owner of such Note for all purposes.
 
AMENDMENT, SUPPLEMENT AND WAIVER
 
     Subject to certain exceptions, the Indenture or the Notes may be amended or
supplemented with the consent (which may include consents obtained in connection
with a tender offer or exchange offer for Notes) of the holders of at least a
majority in principal amount of the Notes then outstanding, and any existing
Default under, or compliance with any provision of, the Indenture may be waived
(other than any continuing Default or Event of Default in the payment of the
principal of, premium, if any, or interest on the Notes) with the consent (which
may include consents obtained in connection with a tender offer or exchange
offer for Notes) of the holders of a majority in principal amount of the Notes
then outstanding; provided that:
 
          (A) no such modification or amendment may, without the consent of the
     holders of 75% in aggregate principal amount of such series of Notes then
     outstanding, amend or modify the obligations of the Company under the
     caption "Change of Control" or the definitions related thereto that could
     adversely affect the rights of any holder of the Notes; and
 
          (B) without the consent of each holder affected, the Company, the
     Subsidiary Guarantors and the Trustee may not: (i) extend the maturity of
     any Note; (ii) affect the terms of any scheduled payment of interest on or
     principal of the Notes (including, without limitation any redemption
     provisions) (iii) take any action that would subordinate the Notes or the
     Note Guarantees to any other Indebtedness of the Company or any of
     Guarantors, respectively (except as provided under "Subordination" above),
     or otherwise affect the ranking of the Notes or the Note Guarantees; or
     (iv) reduce the percentage of holders necessary to consent to an amendment,
     supplement or waiver to the Indenture.
 
          Without the consent of any holder, the Company, the Subsidiary
     Guarantors and the Trustee may amend or supplement the Indenture or the
     Notes to cure any ambiguity, defect or inconsistency, to provide for
     uncertificated Notes in addition to or in place of certificated Notes, to
     provide for the
 
                                       79
<PAGE>   87
 
     assumption of the Company's obligations to holders in the case of a merger
     or acquisition, to make any change that does not adversely affect the
     rights of any holder, to secure the Notes pursuant to the requirements of
     the covenant described under the caption "-- Certain
     Covenants -- Limitations on Liens," to add any additional Guarantor or to
     release any Guarantor from its Note Guarantee, in each case as provided in
     the Indenture, or to comply with requirements of the Commission in order to
     effect or maintain the qualification of the Indenture under the Trust
     Indenture Act.
 
CONCERNING THE TRUSTEE
 
     Marine Midland Bank is the Trustee under the Indenture and has been
appointed by the Company as Registrar and Paying Agent with regard to the Notes.
The Indenture contains certain limitations on the rights of the Trustee, should
it become a creditor of the Company, to obtain payment of claims in certain
cases, or to realize on certain property received in respect of any such claim
as security or otherwise. The Trustee will be permitted to engage in other
transactions; however, if it acquires any conflicting interest (as defined in
the Indenture), it must eliminate such conflict or resign.
 
     The holders of a majority in principal amount of the then outstanding Notes
will have the right to direct the time, method and place of conducting any
proceeding for exercising any remedy available to the Trustee, subject to
certain exceptions. The Indenture provides that, in case an Event of Default
occurs and is not cured, the Trustee will be required, in the exercise of its
power, to use the degree of care of a prudent person in similar circumstances in
the conduct of his own affairs. Subject to such provisions, the Trustee will be
under no obligation to exercise any of its rights or powers under the Indenture
at the request of any holder, unless such holder shall have offered to the
Trustee security and indemnity satisfactory to the Trustee.
 
GOVERNING LAW
 
     Each of the Indenture, the Notes and the Note Guarantees provides that it
will be governed by, and construed in accordance with, the laws of the State of
New York.
 
BOOK-ENTRY, DELIVERY AND FORM OF SECURITIES
 
     The Old Notes were offered and sold to Qualified Institutional Buyers (as
defined in Rule 144A under the Securities Act) in reliance on Rule 144A ("Rule
144A Notes"). Old Notes were also offered and sold in offshore transactions in
reliance on Regulation S under the Securities Act ("Regulation S Notes"). The
Rule 144A Notes and the Regulation S Notes were initially issued in the form of
two global Notes (collectively, the "Old Global Note").
 
     The New Notes issued in exchange for the Rule 144A Notes and the Regulation
S Notes initially will be represented by one or more Notes in registered, global
form without interest coupons, (collectively, the "Global Notes"). The Old
Global Note was deposited on the date of the closing of the sale of the Old
Notes, and the Global Note will be deposited on the date of the closing of the
Exchange Offer, with or on behalf of the Depository Trust Company (the
"Depository") and registered in the name of Cede & Co., as the nominee of the
Depository (such nominee being referred to herein as the "Global Note Holder").
 
     The Depositary has advised the Company that the Depositary is a
limited-purpose trust company that was created to hold securities for its
participating organizations (collectively, the "Participants" or the
"Depositary's Participants") and to facilitate the clearance and settlement of
transactions in such securities between Participants through electronic
book-entry changes in accounts of its Participants. The Depositary's
Participants include securities brokers and dealers (including the Initial
Purchasers), banks and trust companies, clearing corporations and certain other
organizations. Access to the Depositary's system is also available to other
entities such as banks, brokers, dealers and trust companies (collectively, the
"Indirect Participants" or the "Depositary's Indirect Participants") that clear
through or maintain a custodial relationship with a Participant, either directly
or indirectly. Persons who are not Participants may beneficially own securities
held by or on behalf of the Depositary only through the Depositary's
Participants or the Depositary's Indirect Participants.
 
                                       80
<PAGE>   88
 
     The Depositary has also advised the Company that pursuant to procedures
established by the Depositary (i) upon deposit of the Global Notes, the
Depositary will credit the accounts of Participants designated by the Initial
Purchasers with portions of the principal amount of the Global Notes and (ii)
ownership of the Notes will be shown on, and the transfer of ownership thereof
will be effected only through, records maintained by the Depositary (with
respect to the interests of the Depositary's Participants), the Depositary's
Participants and the Depositary's Indirect Participants.
 
     The laws of some states require that certain persons take physical delivery
in definitive form of securities that they own. Consequently, the ability to
transfer the Notes will be limited to such extent.
 
     So long as the Global Note Holder is the registered owner of any Notes, the
Global Note Holder will be considered the sole holder of outstanding Notes
represented by such Global Notes under the Indenture. Except as provided below,
owners of Notes will not be entitled to have Notes registered in their names and
will not be considered the owners or holders thereof under the Indenture for any
purpose, including with respect to the giving of any directions, instructions or
approvals to the Trustee thereunder. None of the Company, the Guarantors or the
Trustee will have any responsibility or liability for any aspect of the records
relating to or payments made on account of Notes by the Depositary, or for
maintaining, supervising or reviewing any records of the Depositary relating to
such Notes.
 
     Payments in respect of the principal of, premium, if any, and interest on
any Notes registered in the name of a Global Note Holder on the applicable
record date will be payable by the Trustee to or at the direction of such Global
Note Holder in its capacity as the registered holder under the Indenture. Under
the terms of the Indenture, the Company and the Trustee may treat the persons in
whose names any Notes, including the Global Notes, are registered as the owners
thereof for the purpose of receiving such payments and for any and all other
purposes whatsoever. Consequently, none of the Company, the Subsidiary
Guarantors or the Trustee has or will have any responsibility or liability for
the payment of such amounts to beneficial owners of Notes (including principal,
premium, if any, and interest). The Company believes, however, that it is
currently the policy of the Depositary to immediately credit the accounts of the
relevant Participants with such payments, in amounts proportionate to their
respective beneficial interests in the relevant security as shown on the records
of the Depositary. Payments by the Depositary's Participants and the
Depositary's Indirect Participants to the beneficial owners of Notes will be
governed by standing instructions and customary practice and will be the
responsibility of the Depositary's Participants or the Depositary's Indirect
Participants.
 
     Subject to certain conditions, any person having a beneficial interest in
the Global Notes may, upon request to the Trustee, exchange such beneficial
interest for Notes in definitive form. Upon any such issuance, the Trustee is
required to register such Notes in the name of, and cause the same to be
delivered to, such person (or the nominee thereof). Such Notes would be issued
in fully registered form and would be subject to the legal requirements
described herein under the caption "Notice to Investors." In addition, if (i)
the Company notifies the Trustee in writing that the Depositary is no longer
willing or able to act as a depositary and the Company is unable to locate a
qualified successor within 90 days or (ii) the Company, at its option, notifies
the Trustee in writing that it elects to cause the issuance of Notes in
definitive form under the Indenture, then, upon surrender by the relevant Global
Note Holder of its Global Note, Notes in such form will be issued to each person
that such Global Note Holder or the Depositary identifies as being the
beneficial owner of the related Notes.
 
     Neither the Company nor the Trustee will be liable for any delay by the
Global Note Holder or the Depositary in identifying the beneficial owners of
Notes and the Company and the Trustee may conclusively rely on, and will be
protected in relying on, instructions from the Global Note Holder or the
Depositary for all purposes.
 
     The Indenture requires that payments in respect of the Notes represented by
a Global Note (including principal, premium, if any, interest and Special
Interest) be made in same-day funds to the accounts specified by the Global Note
Holder.

REGISTRATION RIGHTS
 
     Holders of the New Notes are not entitled to any registration rights with
respect to the New Notes. The Company as agreed for such time period as
broker-dealers must comply with the prospectus delivery requirements of the
Exchange Act in order to resell the New Notes, the Company will make available a
prospectus meeting the requirements of the Securities Act to any broker-dealer
for use in connection with any resale of the New Notes. The Registration
Statement constitutes the registration statement for the Exchange Offer which is
the subject of the Registration Rights Agreement. Upon the closing of the
Exchange Offer, subject to certain limited exceptions, Holders of untendered Old
Notes will not retain any rights under the Registration Rights Agreement.

     cover any property or assets of the Company or of any Restricted Subsidiary
     other than the property or assets that secured the Acquired Indebtedness
     prior to the time such Indebtedness became Acquired Indebtedness of the

such Subsidiary so designated for purposes of the "Limitations on Additional
Indebtedness" covenant as of the date of such designation, provided that such

                              PLAN OF DISTRIBUTION
 
     There has previously been only a limited secondary market and no public
market for the Old Notes. The Company does not intend to apply for the listing
of the Notes on a national securities exchange or for their quotation through
The Nasdaq Stock Market. The Old Notes are eligible for trading in the PORTAL
market. Therefore, there can be no assurance that an active market for the Old
Notes or the New Notes will develop.
 
     If a trading market develops for the Old Notes or the New Notes, future
trading prices of such securities will depend on many factors, including, among
other things, prevailing interest rates, the Company's results of operations and
the market for similar securities. Depending on such factors, such securities
may trade at a discount from their offering price.
 
     With respect to resale of New Notes, based on an interpretation by the
staff of the SEC set forth in no-action letters issued to third parties, the
Company believes that a holder (other than a person that is an affiliate of the
Company within the meaning of Rule 405 under the Securities Act or "broker" or
"dealer" registered under the Exchange Act) who exchanges Old Notes for New
Notes in the ordinary course of business and who is not participating, does not
intend to participate, and has no arrangement or understanding with any person
to participate, in the distribution of the New Notes, will be allowed to resell
the New Notes to the public without further registration under the Securities
Act and without delivering to the purchasers of the New Notes a prospectus that
satisfies the requirements of Section 10 thereof. However, if any holder
acquires New Notes in the Exchange Offer for the purpose of distributing or
participating in a distribution of the New Notes, such holder cannot rely on the
position of the staff of the SEC enunciated in Exxon Capital Holdings
Corporation (available May 13, 1988) or similar no-action or interpretive
letters and must comply with the registration and prospectus delivery
requirements of the Securities Act in connection with a secondary resale
transaction, and such secondary resale transaction must be covered by an
effective registration statement containing the security holder information
required by Item 507 or 508, as applicable, of Regulation S-K if the resales are
of New Notes obtained by such holder in exchange for Old Notes acquired by such
holder directly from the Company or an affiliate thereof, unless an exemption
from registration is otherwise available.
 
     As contemplated by the above no-action letters and the Registration Rights
Agreement, each holder accepting the Exchange Offer is required to represent to
the Company in the Letter of Transmittal that (i) the New Notes are to be
acquired by the holder in the ordinary course of business, (ii) the holder is
not engaging and does not intend to engage in the distribution of the, and (iii)
the holder acknowledges that if such holder participates in the Exchange Offer
for the purpose of distributing the New Notes such holder must comply with the
registration and prospectus delivery requirements of the Securities Act and
cannot rely on the above no-action letters.
 
     Any broker or dealer registered under the Exchange Act (each a
"broker-dealer") who holders Old Notes that were acquired for its own account as
a result of market-making activities or other trading activities (other than Old
Notes acquired directly from the Company) may exchange such Old Notes for New
Notes pursuant to the Exchange Offer; however, such broker-dealer may be deemed
an underwriter within the meaning of the Securities Act and, therefore, must
deliver a prospectus meeting the requirements of the Securities Act in
connection with any resales of the New Notes received by it in the Exchange
Offer, which prospectus delivery requirement may be satisfied by the delivery by
such broker-dealer of this Prospectus. The Company has agreed to cause the
Registration Statement, of which this Prospectus is a part, to remain
continuously effective, and to make this Prospectus, as amended or supplemented,
available to any such broker-dealer for use in connection with resales. Any
broker-dealer Participating in the Exchange Offer will be required to
acknowledge that it will deliver a prospectus in connection with any resales of
New Notes received by it in the Exchange Offer. The delivery by a broker-dealer
of a prospectus in connection with resales of New Notes shall not be deemed to
be an admission by such broker-dealer that it is an underwriter within the
meaning of the Securities Act.
 
     The Company will not receive any proceeds from any sale of New Notes by
broker dealers. New Notes received by broker dealers for their own account
pursuant to the Exchange Offer may be sold from time to time in one or more
transactions in the over-the-counter market, in negotiated transactions through
the writing of options on the New Notes or a combination of such methods of
resale, at market prices prevailing at the
                                       95
<PAGE>   103
 
time of resale, at prices related to such prevailing market prices or negotiated
prices. Any such resale may be made directly to a purchaser or to or through
brokers or dealers who may receive compensation in the form of commissions or
concessions from any such broker-dealer and/or the purchasers of any such New
Notes.
 
     The Company has agreed to pay all expenses incident to the Exchange Offer
other than fees and disbursements of counsel to holders of Old Notes,
underwriting commissions and discounts, brokerage commissions, agent fees (other
than the fees of the Exchange Agent) and transfer taxes relating to the
Registration Statement.
 
                 CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS
 
     The following is a summary of certain material United States federal income
tax consequences generally applicable to the Notes, including the tax
consequences of the Exchange Offer to Holders of Old Notes who tender their Old
Notes for New Notes. The U.S. federal income tax considerations set forth below
are based upon currently existing provisions of the United States Internal
Revenue Code of 1986, as amended ("the Code"), applicable Treasury Regulations,
judicial authority, and current administrative rulings and pronouncements of the
Internal Revenue Service (the "IRS"). There can be no assurance that the IRS
will not take a contrary view, and no ruling from the IRS has been, or will be,
sought on the issues discussed herein. Legislative, judicial, or administrative
changes or interpretations may be forthcoming that could alter or modify the
statements and conclusions set forth herein. Any such changes or interpretations
may or may not be retroactive and could affect the tax consequences discussed
below.
 
     As used in this summary, the term "U.S. Holder" means the beneficial owner
of a Note that is for U.S. federal income tax purposes (i) an individual citizen
or resident of the United States, (ii) a corporation or partnership created or
organized in or under the laws of the United States or of any state, (iii) an
estate the income of which is subject to United States federal income tax
regardless of its source, or (iv) a trust whose administration is subject to the
primary supervision of a United States court and which has one or more United
States persons who have the authority to control all substantial decisions of
the trust.
 
     As used in this summary, the term "Non-U.S. Holder" means the beneficial
owner of a Note that is, for U.S. federal income tax purposes, not a U.S.
Holder. As used in this summary the term "Note" means either an "Old Note" or a
"New Note."
 
     The summary is not a complete analysis or description of all potential U.S.
federal income tax considerations that may be relevant to, or of the actual tax
effect that any of the matters described herein will have on, particular U.S.
Holders and Non-U.S. Holders (collectively, "Holders"), and does not address
foreign, state, local or other tax consequences. This summary does not address
the U.S. federal income tax consequences to (a) special classes of taxpayers
(such as S corporations, mutual funds, insurance companies, financial
institutions, small business investment companies, regulated investment
companies, real estate investment trusts, dealers in securities or currencies,
broker-dealers and tax-exempt organizations) who are subject to special
treatment under U.S. federal income tax laws, (b) Holders that hold Notes as
part of a position in a "straddle," or as part of a "hedging," "conversion," or
other integrated investment transaction for U.S. federal income tax purposes,
(c) Holders that do not hold the Notes as capital assets within the meaning of
Section 1221 of the Code or (d) Holders whose functional currency is not the
U.S. dollar. Furthermore, federal estate and gift tax consequences are not
discussed herein.
 
     BECAUSE INDIVIDUAL CIRCUMSTANCES MAY DIFFER, EACH PROSPECTIVE PURCHASER OF
THE NOTES IS STRONGLY URGED TO CONSULT HIS OR HER OWN TAX ADVISOR WITH RESPECT
TO HIS OR HER PARTICULAR TAX SITUATION AND AS TO ANY FEDERAL, FOREIGN, STATE,
LOCAL OR OTHER TAX CONSIDERATIONS (INCLUDING ANY POSSIBLE CHANGES IN TAX LAW)
AFFECTING THE PURCHASE, HOLDING AND DISPOSITION OF THE NOTES.

<PAGE>   104
 
U.S. FEDERAL INCOME TAX CONSEQUENCES TO U.S. HOLDERS
 
Interest
 
     Generally, interest paid on the Notes will be ordinary income to a U.S.
Holder at the time it accrues or is received in accordance with such U.S.
Holder's method of accounting for U.S. federal income tax purposes.
 
Exchange Offer
 
     The exchange of Old Notes for the New Notes pursuant to the Exchange Offer
should not constitute a taxable event for U.S. federal income tax purposes,
because the terms of the New Notes are not materially different from the terms
of the Old Notes. As a result, U.S. Holders exchanging the Old Notes for the New
Notes pursuant to the Exchange Offer should recognize no gain or loss upon
receipt of the New Notes, and a U.S. Holder should have the same tax basis and
holding period in the New Notes as in the Old Notes immediately prior to such
exchange.
 
Disposition of the Notes
 
     Upon the sale, exchange or retirement of a Note (other than pursuant to the
Exchange Offer), a U.S. Holder will recognize capital gain or loss equal to the
difference between the amount realized on the sale, exchange or retirement
(except to the extent attributable to accrued interest that has not been
included in income) and such U.S. Holder's adjusted tax basis in the Note at the
time of such disposition. Amounts attributable to accrued interest that have not
been included in income will be taxable as ordinary income. Prospective
investors should consult their tax advisors regarding the treatment of capital
gains and losses.
 
     The Company does not intend to treat the possibility of an optional
redemption or repurchase of the Notes as giving rise to any accrual of original
issue discount or recognition of ordinary income upon redemption, sale or
exchange of a Note. U.S. Holders may wish to consider that Treasury Regulations
regarding the treatment of certain contingencies were recently issued and may
wish to consult their tax advisors in this regard.
 
Backup Withholding
 
     A non-corporate U.S. Holder of the Notes may be subject to backup
withholding at the rate of 31 percent with respect to "reportable payments,"
which include interest paid on or the proceeds of a sale, exchange or redemption
of, the Notes. The payor will be required to deduct and withhold the prescribed
amounts if (i) the payee fails to furnish a Taxpayer Identification Number
("TIN") to the payor in the manner required, (ii) the IRS notifies the payor
that the TIN furnished by the payee is incorrect, (iii) there has been a
"notified payee underreporting" described in Section 3406(c) of the Code or (iv)
there has been a failure of the payee to certify under penalty of perjury that
the payee is not subject to withholding under Section 3406(a)(1)(C) of the Code.
If any one of the events listed above occurs, the payor will be required to
withhold an amount equal to 31 percent from any interest payment made with
respect to the Notes or any payment of proceeds of a redemption of the Notes to
a non-corporate U.S. Holder. Amounts paid as backup withholding do not
constitute an additional tax and will be credited against the U.S. Holder's
federal income tax liability, so long as the required information is provided to
the IRS. The payor generally will report to the U.S. Holders of the Notes and to
the IRS the amount of any "reportable payments" for each calendar year and the
amount of tax withheld, if any, with respect to payment on those securities.
 
TAX CONSEQUENCES TO NON-U.S. HOLDERS
 
Interest
 
     Interest paid by the Company to a Non-U.S. Holder will not be subject to
U.S. federal income or withholding tax if such interest is not effectively
connected with the conduct of a trade or business within the United States (or a
permanent establishment therein, if a tax treaty applies) by such Non-U.S.
Holder and such Non-U.S. Holder (i) does not actually or constructively own 10%
or more of the total combined voting power of all classes of stock of the
Company; (ii) is not a controlled foreign corporation, as defined in Section
 
                                       97
<PAGE>   105
 
957 of the Code, with respect to which the Company is a "related person"; (iii)
is not a bank receiving the interest on an extension of credit made pursuant to
a loan agreement entered into in the ordinary course of its trade or business;
and (iv) certifies, under penalties of perjury, that such Holder is not a United
States person and provides the Company with such Holder's name and address, or a
securities clearing organization, bank, or other financial institution that
holds customers' securities in the ordinary course of its trade or business
certifies, under penalties of perjury, that such certification and information
has been received by it or a qualifying intermediary from the Non-U.S. Holder
and furnishes the Company with a copy thereof.
 
     If a Non-United States Holder of a Note is engaged in a trade or business
in the United States, and if interest on the Note (or gain realized on its sale,
exchange or other disposition) is effectively connected with the conduct of such
trade or business, the Non-U.S. Holder, although exempt from the withholding tax
discussed in the preceding paragraph, will generally be subject to regular U.S.
federal income tax on such effectively connected income in the same manner as if
it were a U.S. Holder. See "U.S. Holders" above. Such Holder will be required to
provide to the withholding agent a properly executed IRS Form 4224 (or, after
December 31, 1998, a Form W-8) to claim an exemption from withholding tax. In
addition, if such Non-U.S. Holder is a non-U.S. corporation, it may be subject
to a 30% branch profits tax (unless reduced or eliminated by an applicable
treaty) on its effectively connected earnings and profits for the taxable year,
subject to certain adjustments. For purposes of the branch profits tax, interest
on, and any gain recognized on the sale, exchange or other disposition of, a
Note will be included in the effectively connected earnings and profits of such
Non-U.S. Holder if such interest or gain, as the case may be, is effectively
connected with the conduct by the Non-U.S. Holder of a trade or business in the
United States.
 
Gain on Disposition
 
     A Non-U.S. Holder will generally not be subject to U.S. federal income tax
on gain recognized on a sale, redemption or other disposition of a Note unless
(i) the gain is effectively connected with the conduct of a trade or business
within the United States (or a permanent establishment therein, if a tax treaty
applies) by the Non-U.S. Holder, (ii) in the case of a Non-U.S. Holder who is a
nonresident alien individual and holds the Note as a capital asset, such Holder
is present in the United States for 183 or more days in the taxable year and
certain other requirements are met, or (iii) the Holder is subject to tax
pursuant to the provisions of the Code applicable to certain United States
expatriates.
 
Information Reporting and Backup Withholding
 
     The Company will, where required, report to the Non-U.S. Holders of Notes
and the IRS the amount of any interest paid on the Notes in each calendar year
and the amounts of tax withheld, if any, with respect to such payments.
 
     In the case of payments of interest to Non-U.S. Holders, Treasury
Regulations provide that the 31% backup withholding tax and certain information
reporting will not apply to payments with respect to which either the requisite
certification, as described above, has been received or an exemption has
otherwise been established; provided that neither the Company nor its payment
agent has actual knowledge that the Non-U.S. Holder is a United States person or
that the conditions of any other exemption are not in fact satisfied. Under
Treasury Regulations, these information reporting and backup withholding
requirements will apply, however, to the gross proceeds paid to a Non-U.S.
Holder on the disposition of the Notes by or through a United States office of a
United States or foreign broker, unless such Holder certifies to the broker
under penalties of perjury as to its name, address and status as a foreign
person or the Holder otherwise establishes an exemption. Information reporting
requirements, but not backup withholding, will also apply to a payment of the
proceeds of a disposition of the Notes by or through a foreign office of a
United States or foreign broker with certain types of relationships to the
United States unless such broker has documentary evidence in its file that the
Non-U.S. Holder of the Notes is not a United States person, and such broker has
no actual knowledge to the contrary, or the Non-U.S. Holder otherwise
establishes an exemption. Neither information reporting nor backup withholding
generally will apply to a payment of the proceeds of a disposition of the Notes
by or through a foreign office of a foreign broker not described in the
preceding sentence.
 
                                       98

     Recently adopted Treasury Regulations regarding the withholding and
information reporting rules discussed above do not, in general, alter the
substantive withholding and information reporting requirements but unify current
certification procedures and forms and clarify reliance standards. These
Treasury Regulations will become effective for payments made after December 31,
1998, subject to certain transition rules.
 
     Backup withholding is not an additional tax. Any amounts withheld under the
backup withholding rules may be refunded or credited against the Non-U.S.
Holder's U.S. federal income tax liability, provided that the required
information is furnished to the IRS.

                          INDEPENDENT AUDITORS' REPORT
 
Pool Energy Services Co.:
 
     We have audited the accompanying consolidated balance sheets of Pool Energy
Services Co. and its subsidiaries (the "Company") as of December 31, 1997 and
1996, and the related statements of consolidated operations and cash flows for
each of the three years in the period ended December 31, 1997. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on the 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 audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, such consolidated financial statements present fairly, in
all material respects, the financial position of Pool Energy Services Co. and
its subsidiaries at December 31, 1997 and 1996, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1997 in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     All dollar amounts in the tabulations in the notes to the consolidated
financial statements are stated in thousands unless otherwise indicated. All
dollar amounts included in the text are in whole dollars, unless otherwise
indicated. Certain reclassifications have been made in the 1995 and 1996
consolidated financial statements to conform with the 1997 presentation.
 
THE COMPANY
 
     Pool Energy Services Co. (the "Company") was formed in November 1988 to
acquire all of the oilfield services business of ENSERCH Corporation
("ENSERCH"), and such acquisition was consummated in April 1990. As used herein,
except where the context otherwise requires, the term "Company" refers to Pool
Energy Services Co., its subsidiary corporations and its unconsolidated
affiliates. The Company operates in only one business segment - the oilfield
services industry. Within the oilfield services industry, the Company provides
services and products to oil and natural gas well operators for the workover,
maintenance and plugging of existing oil and natural gas wells and for the
drilling and completion of new oil and natural gas wells. The Company operates
in the United States, South America, the Middle East, Asia and Australia.
 
PRINCIPLES OF CONSOLIDATION
 
     The consolidated financial statements include the financial statements of
the Company and all subsidiaries in which a controlling interest is held. All
significant intercompany accounts and transactions have been eliminated in
consolidation. The Company uses the equity method to account for affiliates in
which it does not have control. The Company acquired a 51% controlling interest
in a newly formed Argentina corporation, Pool International Argentina S.A.
("PIASA"), in August 1996 (see Note 3). For financial reporting purposes, 100%
of the assets, liabilities, results of operations and cash flows of PIASA are
consolidated with those of the Company. The minority shareholder's interest in
PIASA and the earnings or losses therefrom have been reflected as "minority
interest" in the Company's consolidated financial statements.
 
     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.
 
REVENUE RECOGNITION
 
     The Company generally recognizes revenue when services are rendered or
products are shipped.
 
FOREIGN CURRENCY GAINS AND LOSSES
 
     The U.S. dollar is the functional currency for all of the Company's foreign
operations, and for those operations, foreign currency gains and losses are
included in the statement of consolidated operations as incurred. The cumulative
translation gains and losses reflected as a separate component of shareholders'
equity arose prior to April 1996, when the functional currency of the Company's
then unconsolidated affiliate in Trinidad was the Trinidad and Tobago dollar.
 
PROPERTY, PLANT AND EQUIPMENT
 
     Depreciation of plant and equipment is provided on a straight-line basis
over the estimated useful lives of the assets. The components of a rig that
generally require replacement during the rig's life have useful lives that range
from three to 12 years. The basic rigs, excluding such components, have
estimated useful lives from

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
date of original manufacture ranging from 22 to 35 years. Other property and
equipment have useful lives that range from three to seven years. Estimated
salvage values are assigned to the rigs based on an individual assessment of
each rig and generally approximate 15% of cost.
 
     Effective January 1, 1996 the Company adopted Financial Accounting
Standards Board Statement No. 121, "Accounting for the Impairment of Long-Lived
Assets and for Long-Lived Assets to Be Disposed Of." This statement requires
that long-lived assets including certain identifiable intangibles held and used
by the Company be reviewed for impairment whenever events or changes in
circumstances indicate that the carrying amount of an asset may not be
recoverable. Since adoption of this statement no impairment losses have been
recognized.
 
GOODWILL
 
     Goodwill, totaling $42.4 million and $12.9 million at December 31, 1997 and
1996, respectively, represents the cost in excess of fair value of the net
assets of companies acquired (see Note 3). Goodwill is amortized using the
straightline method over 25 to 30 years and is recorded net of accumulated
amortization of $1.3 million and $0.6 million at December 31, 1997 and 1996,
respectively. Amortization of goodwill for the years ended December 31, 1997,
1996 and 1995 amounted to $0.7 million, $0.4 million and $0.2 million,
respectively. The carrying amount of unamortized goodwill is reviewed for
potential impairment loss when events or changes in circumstances indicate that
the carrying amount of goodwill may not be recoverable.
 
ENVIRONMENTAL REMEDIATION AND COMPLIANCE
 
     Costs incurred to investigate and remediate contaminated sites are expensed
unless the remediation extends the useful lives of the assets employed at the
site. Remediation costs that extend the useful lives of the assets are
capitalized and amortized over the remaining economic lives of such assets.
Liabilities are recorded when the need for environmental assessments and/or
remedial efforts become known or probable and the cost can be reasonably
estimated.
 
INCOME TAXES
 
     The Company is subject to both U.S. and foreign income taxes. The Company
accounts for income taxes based upon Statement of Financial Accounting Standards
No. 109, "Accounting for Income Taxes" which requires recognition of deferred
income tax liabilities and assets for the expected future tax consequences of
events that have been recognized in the Company's financial statements or tax
returns. Under this method, deferred income tax liabilities and assets are
determined based on the temporary differences between the financial statement
carrying amounts and the tax bases of existing assets and liabilities and
available tax credit carryforwards.
 
INVENTORIES
 
     Inventories of spare parts, materials and supplies held for consumption are
stated principally at average cost.
 
CONCENTRATION OF CREDIT RISK
 
     Financial instruments which potentially subject the Company to
concentrations of credit risk consist primarily of temporary cash investments
and trade receivables. The Company restricts temporary cash investments to
financial institutions with high credit standing and by policy limits the amount
of credit exposure to any one financial institution. The Company's customer base
consists primarily of multi-national, foreign national and independent oil and
natural gas producers. During 1997, no single customer accounted for more than
10% of the Company's consolidated revenues. One customer accounted for
approximately 11% of the Company's consolidated revenues in both 1996 and 1995.
The Company performs ongoing credit

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
evaluations of its customers and generally does not require collateral on its
trade receivables. Such credit risk is considered by management to be limited
due to the large number of customers comprising the Company's customer base. The
Company maintains reserves for potential credit losses, and such losses have
been within management's expectations.
 
FAIR VALUES OF FINANCIAL INSTRUMENTS
 
     Except for investments in its unconsolidated affiliates, which are
accounted for under the equity method, the Company's financial instruments
consist primarily of variable rate items for which management believes fair
value approximates carrying value.
 
FOREIGN EXCHANGE RISK MANAGEMENT
 
     The Company operates internationally, giving rise to exposure to market
risks from changes in foreign exchange rates to the extent that transactions are
not denominated in the U.S. dollar. The Company uses forward exchange contracts
as economic hedges of exposed net investments in foreign entities in which that
exposure exceeds $0.2 million and for which contracts in the appropriate
currency are available. The Company's foreign exchange contracts do not subject
the Company to the risk of exchange rate movements because gains and losses on
these contracts offset gains and losses on the exposed investments being hedged.
Realized and unrealized gains and losses on these contracts are recognized
currently in the statement of consolidated operations. The forward exchange
contracts generally have maturities which do not exceed 31 days. The Company had
forward exchange contracts to purchase $2.3 million in Australian dollars, $1.8
million in Argentine pesos and $1.7 million in Malaysian ringgits at December
31, 1997 and $2.5 million in Malaysian ringgits and $2.0 million in Australian
dollars at December 31, 1996. The Company does not hold or issue financial
instruments for trading purposes.
 
STOCK INCENTIVE PLANS
 
     The Company accounts for stock option grants to employees using the
intrinsic value method of accounting prescribed by APB Opinion No. 25,
"Accounting for Stock Issued to Employees" ("APB 25"). Under the Company's stock
incentive plans, the price of the stock on the grant date is the same as the
amount an employee must pay to exercise the option to acquire the stock;
accordingly, the options have no intrinsic value at grant date, and in
accordance with the provisions of APB 25 no compensation cost is recognized.
 
     In October 1995, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation" ("SFAS 123"), which sets forth alternative accounting and
disclosure requirements for stock-based compensation arrangements. SFAS 123 does
not rescind the existing accounting for employee stock-based compensation under
APB 25. Companies may continue to follow the current accounting to measure and
recognize employee stock-based compensation; however, SFAS 123 requires
disclosure of pro forma net income and earnings per share that would have been
reported under the "fair value" based recognition provisions of SFAS 123. The
Company has disclosed in Note 2 the pro forma information required under SFAS
123.
 
CASH EQUIVALENTS
 
     The Company considers all unrestricted highly liquid investments with less
than a three-month maturity when purchased as cash equivalents.
 
EARNINGS PER SHARE OF COMMON STOCK
 
     In February 1997, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 128, "Earnings Per Share," which
establishes new standards for computing, presenting and
 
                                       F-8

COMMON STOCK
 
     In July 1996, the Company completed the sale to the public of 4,600,000
shares of its common stock, no par value, from which it received cash proceeds
of approximately $47.5 million, net of expenses. The Company used the net
proceeds principally as follows: (i) $10.9 million in connection with the August
1996 acquisition of a 51% controlling interest in PIASA, a newly formed
Argentina corporation which provides well-servicing, workover and drilling
services in Argentina, (ii) approximately $9 million in connection with the
October 1996 acquisition of the 51% interest not already owned by the Company in
Antah Drilling Sdn. Bhd. ("Antah Drilling"), (iii) $4.5 million in connection
with the June 1996 Western Oil Well Service Co. ("Western Oil") asset
acquisition, (iv) $8.4 million in connection with the refurbishment of Rig 18, a
previously idle platform drilling rig in the Gulf of Mexico, and (v) for
repayment of debt under the Company's syndicated bank revolving line of credit
and general corporate purposes. The amounts described above include both
acquisition expenditures and related working capital advances. See Note 3 for
additional descriptions of these acquisitions.

PREFERRED STOCK
 
     The 1,000 shares of the Company's authorized and issued preferred stock is
currently held in treasury.
 
SHAREHOLDER RIGHTS PLAN
 
     The Company maintains a Shareholder Rights Plan (the "Rights Plan") that is
designed to deter coercive or unfair takeover tactics, to prevent a person or
group from gaining control of the Company without offering fair value to all
shareholders and to deter other abusive takeover tactics which are not in the
best interests of shareholders. The Company's Board of Directors adopted the
Rights Plan in June 1994 and declared a dividend to the shareholders of one
right ("Right") for each outstanding share of the Company's common stock. The
Rights only become exercisable, and transferable apart from the Company's common
stock, ten business days following a public announcement that a person or group
("Acquirer") has acquired beneficial ownership of, or has commenced a tender or
exchange offer for, 15% or more of the Company's common stock (each a
"Triggering Event").
 
     Each Right initially entitles the holder to purchase one-third of one share
of the Company's common stock at a price of $9.00, subject to adjustment. Upon
the occurrence of a Triggering Event, each Right, in the absence of timely
redemption of the Rights by the Company, will entitle the holder thereof (other
than the Acquirer), instead, to receive upon exercise of the Right a number of
the Company's common shares (or, in certain circumstances, cash, property or
other securities of the Company) having a current market value equal to twice
the exercise price for a full share of common stock. Following the occurrence of
a Triggering Event, if the Company is acquired in a merger or other business
combination, or 50% or more of the Company's assets or earning power are sold or
transferred, each Right, in the absence of timely redemption of the Rights by
the Company, will entitle the holder thereof (other than the Acquirer) to
receive a number of shares of common stock of the acquiring company having a
current market value equal to twice the exercise price for a full share of
common stock.
 
     The Rights may be redeemed by the Company in whole, but not in part, at a
redemption price of $.01 per Right at any time prior to the Rights becoming
exercisable. The Rights will expire in June 2004. Until the Rights become
exercisable, they have no dilutive effect on earnings per share. As of December
31, 1997, a total of 5,994,337 shares of the Company's common stock were
reserved for issuance upon exercise of Rights.
 
     The description and terms of the Rights are set forth in a Rights Agreement
between the Company and the First National Bank of Boston, as Rights Agent.
 
STOCK INCENTIVE PLANS
 
     The Company's 1993 Employee Stock Incentive Plan is for officers and key
employees, which plan reserved for issuance up to 600,000 shares of the
Company's common stock. In 1997, the plan was amended to increase the number of
shares of the Company's common stock reserved for issuance thereunder by 850,000
shares (thereby resulting in 1,450,000 shares reserved). The shares may be
issued upon the exercise of non-qualified stock options granted under the plan
or may be granted as restricted stock awards or bonus stock awards. Subject to
earlier termination under certain circumstances, stock options are exercisable
over a ten-year term and, unless specified otherwise at the time of the grant,
vest at the rate of 25 percent per year of continuous employment following the
grant of the options. As of December 31, 1997 the Company had issued 86,407
shares as a result of the exercise of options pursuant to such plan. Shares of
common stock awarded as restricted stock are subject to restrictions on transfer
and subject to risk of forfeiture until earned by continued employment or the
achievement of specific goals. During the restriction period, holders of
restricted stock have the right to vote; cash dividends, if any, are accrued but
not paid until satisfaction of the applicable restrictions. As of December 31,
1997, the Company had awarded 65,649 shares of restricted stock, net of
forfeitures, pursuant to such plan.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     The Company also has a 1990 Employee Stock Option Plan for officers and key
employees, which plan reserved for issuance up to 1,000,000 shares of the
Company's common stock, of which 627,737 shares had been issued as of December
31, 1997 through the exercise of options. Subject to earlier termination under
certain circumstances, options are exercisable over a ten-year term and, unless
specified otherwise at the time of the grant, vest at the rate of 25 percent per
year of continuous employment following the grant of the options. Since the
adoption of the 1993 Employee Stock Incentive Plan, no additional options may be
granted under the 1990 Employee Stock Option Plan.
 
     Effective February 1996, the Company adopted the 1996 Directors' Stock
Incentive Plan for members of its Board of Directors who are not full-time
employees of the Company. The plan reserved for issuance up to 200,000 shares of
the Company's common stock which may be issued upon the exercise of stock
options or may be awarded as restricted stock. The plan provides for each person
who is elected or appointed a director for the first time after the effective
date to receive automatically an initial stock option of 8,000 shares and to
receive automatically a stock option for 4,000 shares on the date of each Annual
Meeting of Shareholders after the initial grant at which such director is
reelected. Options expire ten years after the date of grant. Each option becomes
exercisable at the end of one year from the date of grant. Also, each director
receives an award of 1,000 shares of restricted stock, with a one-year
restriction period, on the date of each Annual Meeting of Shareholders. As of
December 31, 1997, the Company had issued 8,000 shares as the result of the
exercise of options and had awarded 11,000 shares of restricted stock, net of
forfeitures, pursuant to such plan.
 
     The Company also has a 1991 Directors' Stock Option Plan for members of its
Board of Directors who are not full-time employees of the Company. Such plan
reserved for issuance up to 150,000 shares of the Company's common stock, of
which 56,000 shares had been issued as of December 31, 1997 through the exercise
of options. Subject to earlier termination under certain circumstances, options
expire ten years after the date of the grant. Each option becomes exercisable as
to 50% of the shares covered thereby at the end of one year from the date of
grant and as to the remaining 50% at the end of two years from the date of
grant. Since the adoption of the 1996 Directors' Stock Incentive Plan no
additional options may be granted under the 1991 Directors' Stock Option Plan.
 
     The fair market value at the date the restricted stock was issued has been
recorded as unearned compensation -- restricted stock and is shown as a separate
component of shareholders' equity. The unearned restricted stock compensation is
amortized to operations over the related restriction period. The following table
summarizes the restricted stock activity related to the Company's plans:

     The exercise price of options under all plans is the fair market value per
share on the date the options are granted. The exercise of stock options results
in a U.S. tax deduction to the Company equal to the income tax effect of the
difference between the exercise price and the market price at the exercise date.
For financial reporting purposes, this tax benefit is accounted for as a credit
to common stock. During 1997 and 1996, $2.1 million and $0.6 million,
respectively, were credited to common stock as a result of the tax benefit

     The Company applies the intrinsic value based method of APB 25 in
accounting for its employee stock incentive plans. Accordingly, no compensation
expense has been recognized for any stock options issued under the employee
plans. Had compensation expense for stock options granted to employees been
recognized based on the fair value at the grant dates, using the methodology
prescribed by SFAS 123, the Company's net income and earnings per share would
have been reduced to the pro forma amounts indicated below:

3.  ACQUISITIONS
 
1997 ACQUISITIONS
 
     A.A. Oilfield Service, Inc.  In November 1997, the Company acquired all of
the outstanding capital stock of privately owned A.A. Oilfield Service, Inc.
("A.A.") for $4.1 million in cash. This acquisition included 18 oilfield trucks,
one salt water disposal well and related equipment based in Hobbs, New Mexico.
This acquisition was financed through borrowings under the Company's syndicated
bank revolving line of credit.
 
     Trey Services, Inc.  In October 1997, the Company acquired all of the
outstanding capital stock of Trey Services, Inc. ("Trey") and certain associated
operating assets for cash of $31.3 million. Prior to the acquisition, Trey,
through its wholly-owned subsidiary R & H Well Service, Inc. ("R&H"), operated a
fleet of approximately 67 land well-servicing rigs, 104 oilfield trucks, 430
fluid storage tanks and five brine and disposal wells in the Permian Basin of
West Texas. This acquisition was financed through borrowings under the Company's
syndicated bank revolving line of credit.
 
     D A & S Oil Well Servicing, Incorporated.  In June 1997, the Company
acquired all of the outstanding capital stock of D A & S Oil Well Servicing,
Incorporated ("DA&S"), a privately owned well-servicing company with a fleet of
37 land well-servicing rigs, for $10.5 million, consisting of long-term notes in
the amount of $10.1 million and $0.4 million in cash.
 
     Each of the 1997 acquisitions discussed above was recorded under the
purchase method of accounting, and accordingly, the results of operations of
each acquired entity have been included in the accompanying consolidated
financial statements from the date such entity was acquired. The purchase price
of each acquisition was allocated based on preliminary estimates of the fair
market value of the assets acquired and liabilities assumed at the date of
acquisition and is subject to adjustment as additional information becomes
available and is evaluated. The primary areas subject to further purchase price
adjustment are reserves associated with insurance related matters and taxes.
Such allocations resulted in goodwill of approximately $30.4 million, which is
being amortized on a straight-line basis over 25 years.
 
1996 ACQUISITIONS
 
     Antah Drilling Sdn. Bhd.  In October 1996, the Company acquired the 51%
interest that it did not already own in Antah Drilling and, in March 1997, such
entity's name was changed to Pool International (Malaysia) Sdn. Bhd. ("Pool
Malaysia"). The purchase price and the repayment of certain indebtedness that
Antah Drilling owed to the Company's former partner in that venture totaled $9.0
million. Pool Malaysia's assets include Rig 489, a 2,000 horsepower offshore
platform drilling rig, which commenced a three-year contract in Australia in
August 1996, and an offshore platform workover rig currently operating under a
term contract in Malaysia. In connection with the Antah Drilling acquisition,
the Company agreed to assume liability under Antah Drilling's term loans, which
aggregated $14.6 million (see Note 6). Prior to the date of acquisition, Antah
Drilling was accounted for under the equity method based upon the Company's 49%
ownership interest.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     Pool International Argentina S. A.  In August 1996, the Company acquired
for approximately $8.7 million in cash a 51% controlling interest in PIASA.
PIASA owns nine land drilling rigs and 11 land workover rigs, all of which are
located in Argentina.
 
     Each of the 1996 acquisitions discussed above was recorded under the
purchase method of accounting and, accordingly, the results of operations of
each acquired entity have been included in the accompanying consolidated
financial statements from the date such entity was acquired. The purchase price
of each acquisition was allocated based on the estimated fair market value of
the assets acquired and liabilities assumed at the date of acquisition. Such
allocations resulted in goodwill of approximately $1.6 million, which is being
amortized on a straight-line basis over 30 years.
 
     Western Oil.  In June 1996, the Company purchased the operating assets,
including approximately 23 land well-servicing rigs, of Western Oil for
approximately $4.0 million in cash.
 
1995 ACQUISITION
 
     Golden Pacific Corp.  In June 1995, the company acquired all of the
outstanding capital stock of GPC, a privately owned California well servicing
company with a fleet of approximately 155 rigs and related equipment, for $18.8
million, consisting of long-term notes in the amount of $11.5 million, $3.1
million in cash and 493,543 shares of the Company's common stock valued at $4.2
million. The cash paid in the transaction was provided by the Company's existing
syndicated bank revolving line of credit.
 
     In August 1997, the Company entered into an agreement with the sellers of
GPC that resolved certain issues that had arisen in connection with the GPC
purchase agreement (see Note 6).
 
     The acquisition was accounted for under the purchase method, and
accordingly the results of GPC have been included in the accompanying
consolidated financial statements since the date of acquisition. The purchase
price was allocated on the basis of the estimated fair market value of the
assets acquired and the liabilities assumed as of the date of acquisition. This
allocation resulted in goodwill of approximately $11.7 million, which is being
amortized on a straight-line basis over 30 years. In connection with the
purchase of GPC, the Company recorded acquisition related costs totaling $0.6
million, primarily for yard closings.
 
4.  SUBSEQUENT EVENT
 
     On March 31, 1998, the Company acquired all the outstanding capital stock
of Sea Mar, Inc. ("Sea Mar"), a privately owned Louisiana-based offshore support
vessel company with operations primarily in the Gulf of Mexico, for
approximately $75.9 million in cash (including an estimated $14.7 million in
post-closing purchase price adjustments) and 1,538,462 shares of the Company's
common stock. In addition, the Company agreed to pay additional cash
consideration contingent upon Sea Mar exceeding certain financial targets for
the fiscal years ending December 31, 1998 and 1999, up to a maximum of $10
million in each year. Sea Mar has a diversified fleet of 23 support vessels,
including one anchor handling/tug supply vessel, 13 supply vessels, seven
mini-supply vessels and two research vessels. Furthermore, during 1997 Sea Mar
contracted with a marine vessel builder to construct ten additional vessels at
an estimated aggregate cost of $77.6 million, net of deposits. These new vessels
are scheduled to be delivered between late 1998 and early 2000. Sea Mar's
services include the marine transportation of drilling materials, supplies and
crews for offshore rig operations and support for other offshore facilities. It
also provides offshore logistical support to drilling and workover operations,
pipelaying and other construction, production platforms and geophysical
operations. For the year ended December 31, 1997, Sea Mar reported revenues of
approximately $46 million and net income of approximately $14 million. The chief
executive officer of Sea Mar will continue to manage the operations of Sea Mar
following the acquisition, under a three-year employment contract. This
transaction, completed on March 31, 1998, was accounted for under the purchase
method.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     The cash portion of the purchase price, the repayment of the existing Sea
Mar debt of $15.7 million by the Company and the reduction of the outstanding
balance under the Company's syndicated revolving bank line of credit was
financed through a private placement of $150 million in senior subordinated
notes (the "Notes") issued by Pool Energy Services Co. ("PESCO") on March 31,
1998 (see Note 6). PESCO itself is a non-operating holding company that conducts
substantially all its business through its subsidiaries. The Notes will be
unconditionally guaranteed, jointly and severally, by all of PESCO's
wholly-owned subsidiaries that are incorporated or organized in the United
States (the "Subsidiary Guarantors"). PESCO's wholly-owned subsidiaries that are
not incorporated or organized in the United States (the "Non-Guarantor
Subsidiaries") will not guarantee the Notes. The Non-Guarantor Subsidiaries are
(i) Pool International, Ltd. (Cayman Islands); (ii) Pool International Malaysia
Sdn. Bhd. (Malaysia); (iii) Pool International Argentina S.A. (Argentina); (iv)
International Sea Drilling Ltd. (Cayman Islands); (v) Pool International
(Trinidad) Ltd. (Trinidad and Tobago) and (vi) ENS Equipment Leasing B.V.
(Netherlands). Although there are no significant legal restrictions under
applicable laws on the ability of PESCO to receive dividends or distributions
from these Non-Guarantor Subsidiaries, the claims of creditors of these
Non-Guarantor Subsidiaries would have priority over the rights of PESCO to
receive such dividends or distributions.
 
     Presented below is condensed consolidating financial information for PESCO,
the Subsidiary Guarantors (on a combined basis), and the Non-Guarantor
Subsidiaries (on a combined basis) as of December 31, 1997 and 1996 and for each
of the three years ended December 31, 1997. Separate financial information of
each Subsidiary Guarantor is not presented because the Company's management has
concluded that such financial information is not material to investors.

</TABLE>
 
     The 1997 and 1996 deferred income tax provisions resulted primarily from a
decrease in deferred tax assets due to utilization of U.S. federal net operating
loss ("NOL") carryforwards. The 1997 current federal provision includes
approximately $3.0 million for alternative minimum tax ("AMT") liability. As AMT
is effectively a prepayment of regular income taxes, a corresponding deferred
tax benefit was also recorded. The 1995 deferred income tax provision resulted
primarily from the effect of certain amendments to prior period U.S. federal tax
returns, partly offset by the reversal of no longer needed deferred foreign
taxes for 1990 income tax indemnities and the elimination of the Company's
valuation allowance related to the NOL carryforwards.
 
     Temporary differences and carryforwards which gave rise to deferred tax
assets and liabilities as of December 31, 1997 and 1996 were as follows:

     In 1995, the Company eliminated the valuation allowance related to its U.S.
federal NOL carryforwards. Management believes that it is now more likely than
not that the Company will generate taxable income sufficient to realize the tax
benefit of the NOL and AMT carryforwards prior to their expiration.
 
     At December 31, 1997, the Company had $3.6 million of NOL and approximately
$3 million of AMT available for carryforward to reduce U.S. federal regular
income taxes payable in future years. The U.S. NOL carryforward is from 1995 and
is available for utilization through the year 2010. The AMT credit carryforward
is primarily from 1997 and can be carried forward indefinitely. State NOL
carryforwards have been substantially reserved for in the Company's consolidated
balance sheet.
 
     The Company had $13.4 million of foreign NOL carryforwards at December 31,
1997, with $1.3 million fully reserved. Management believes the Company will
generate future foreign taxable income sufficient to utilize the remaining $12.1
million of foreign NOL carryforwards with $0.9 million expiring after 2000, $1.6
million expiring after 2001, $1.8 million expiring after 2002 and $7.8 million
being carried forward indefinitely.

     The earnings of the Company's foreign subsidiaries and affiliates are
indefinitely invested outside the United States, and the Company estimates that
no U.S. income taxes would be payable upon distribution of those unremitted
earnings.
 
     The Company is subject to taxation in many jurisdictions, and the final
determination of its tax liabilities involves the interpretation of the statutes
and requirements of various domestic and foreign taxing authorities. At December
31, 1997, foreign income tax returns for prior years of certain foreign
subsidiaries, unconsoli-

     On September 30, 1997, the Company entered into a three-year $130 million
syndicated bank revolving line of credit agreement (the "Line of Credit") to
replace its existing $40 million revolving bank line of credit and $15.6 million
of long-term debt and to provide financing for future growth opportunities. The
maximum availability under the Line of Credit is $130 million, including up to
$15 million that may be used to support letters of credit. At December 31, 1997,
the Company had drawn $65.8 million in cash and $11.8 million was being utilized
to support the issuance of letters of credit, leaving $52.4 million unused and
available. During February 1998, the Company received a commitment for an
increase in the amount available under the Line of Credit from $130 million to
$180 million, which became effective on March 31, 1998. Initially, this
additional financing was considered for use in the financing of the acquisition
of Sea Mar (see Note 4), but instead on March 31, 1998 the Company completed a
private placement of 8 5/8% senior subordinated notes due 2008 in the aggregate
principal amount of $150 million. The net proceeds from the sale of the 8 5/8%
senior subordinated notes were used to fund the cash portion of the purchase
price, to repay the existing debt of Sea Mar and to reduce the outstanding
balance under the Line of Credit. The notes issued under the Line of Credit are
prepayable at any time and are due at expiration on October 2, 2000. The notes
bear interest, at the Company's option, at either (i) a base rate, defined as
the higher of the agent bank's prime lending rate or 1/2 of 1% in excess of the
federal funds rate, plus a margin ranging from zero to .50% (the amount of which
depends on the Company's leverage ratio), or (ii) a Eurodollar rate plus a
margin ranging from 1% to 1.75% (the amount of which depends on the Company's
leverage ratio) with the Company's choice of a one-, two-, three- or six-month
interest period; however, through September 1998, the applicable Eurodollar rate
margin shall not be less than 1.50%. The applicable interest rate was 7.47% at
December 31, 1997. A commitment fee of 1/2 of 1% per annum is payable on the
average daily unused portion of the $130 million commitment. There are also
letter of credit fees that range from 1.25% to 2% per annum (depending on the
Company's leverage ratio) for letters of credit outstanding; however, through
September 1998, such fees shall not be less than 1.75%. Advances under the Line
of Credit are secured by a pledge of 66% of the capital stock of certain of the
Company's foreign subsidiaries. The Company incurred $1.6 million of debt
financing costs during 1997 in connection with the Line of Credit, which is
being amortized over the term of the agreement.

     The Line of Credit agreement imposes certain financial covenants, including
ones requiring the maintenance of a minimum net worth, a minimum interest
coverage ratio, a minimum fixed charge coverage ratio, a maximum leverage ratio
and a maximum debt-to-equity ratio. It also imposes certain other restrictions,
including ones relating to liens, other indebtedness, asset sales, investments,
acquisitions or mergers and payment of dividends. In addition to customary
default provisions, an event of default will occur under the Line of Credit upon
a change of control of the Company, as defined in the agreement.
 
     In June 1997, as partial consideration for the acquisition of DA&S, the
Company issued 9% notes aggregating $10.1 million, the last of which are due in
2003. These notes are collateralized by security interests in (i) the
well-servicing rigs and related equipment of the acquired business, which had an
aggregate net book value of $4.2 million at December 31, 1997 and (ii) certain
real property of the acquired business which had a carrying value of $0.7
million at December 31, 1997.
 
     In connection with the October 1996 acquisition of Antah Drilling (now Pool
Malaysia), the Company agreed to assume liability under Antah Drilling's term
loans, which loans aggregated $14.6 million as of October 1, 1996. In October
1997 the remaining term loan balance was paid off with borrowings under the Line
of Credit. Such loans bore interest at the Singapore Interbank Offered Rate plus
1%, with the Company's choice of a one-, three-, or six-month interest period;
the applicable interest rates approximated 6.65% at December 31, 1996.
 
     In January 1996, the Company received $6.5 million under a term loan
agreement in order to refinance the construction costs incurred during 1995 to
build a new offshore platform workover rig, Rig 453, under contract in
Australia. The rig construction costs were initially funded from the Company's
cash resources and borrowings under its then existing line of credit. This term
loan was paid off in October 1997 with borrowings under the Line of Credit. At
the Company's option, interest accrued at a floating rate based upon (i) the
lenders' prime rate plus 0.5% or (ii) the London Interbank Offered Rate (LIBOR)
plus 2.75%, with the Company's choice of a one-, two-, three- or six-month
interest period. The applicable interest rate on amounts outstanding was 8.13%
at December 31, 1996.
 
     In June 1995, as partial consideration for the acquisition of GPC, the
Company issued 10% notes aggregating $11.5 million due in 2005. The outstanding
principal amount of such notes was reduced $4.0 million as of August 31, 1997 as
a result of an August 1997 agreement between the sellers of GPC ("Sellers") and
the Company that resolved certain issues that had arisen in connection with the
GPC purchase agreement. There was a corresponding $4.0 million increase to
common stock, as the August 1997 agreement effectively revalued the shares of
the Company's common stock received by the Sellers in connection with the June
1995 acquisition. The August 1997 agreement also resulted in a further reduction
of $0.9 million, as of November 30, 1997, of the Sellers' notes in satisfaction
of a receivable from the Sellers of like amount. Due to the principal reductions
described above, payment of these notes is now due to be completed in 2002.
These notes are collateralized by (i) the well-servicing rigs and related
equipment of the acquired business which had an aggregate net book value of $6.8
million at December 31, 1997, (ii) certain real property of the acquired
business which had a carrying value of $1.4 million at December 31, 1997, and
(iii) a $4.5 million letter of credit. The agreement pertaining to the notes
contains various restrictive covenants, including covenants pertaining to the
creation of certain encumbrances, the transaction of certain mergers or sales of
assets, the creation of certain additional debt and other matters.
 
     In April 1995, the Company obtained a three-year term loan (the "Alaska
Loan") to refinance $10 million of the purchase price for the 60.7% partnership
interest in Pool Arctic Alaska which was acquired in September 1994. This term
loan was paid off in October 1997 with borrowings under the Line of Credit. At
the Company's option, interest accrued at a floating rate based upon (i) the
lenders' prime rate plus 0.5%, or (ii) LIBOR plus 2.75%, with the Company's
choice of a one-, two-, three-, or six-month interest period. The applicable
interest rate on amounts outstanding at December 31, 1996 was 8.13%.

     Based on rates currently available to the Company for debt with similar
terms and remaining maturities, the Company believes that the recorded value of
long-term debt approximates fair market value at December 31, 1997.
 
NOTES PAYABLE TO RELATED PARTIES
 
     In connection with the GPC acquisition in June 1995 the Company issued 10%
two-year promissory notes, aggregating $1.5 million in principal amount, to
three employees related to certain deferred compensation obligations of GPC, and
such notes were retired in 1997.
 
SHORT-TERM LINES OF CREDIT
 
     At December 31, 1997, the Company's unconsolidated affiliates had $2.4
million of unused short-term lines of credit and overdraft facilities.
 
7.  COMMITMENTS AND CONTINGENT LIABILITIES
 
LEGAL PROCEEDINGS
 
     The Company is routinely involved in litigation incidental to its business,
which often involves claims for significant monetary amounts, some, but not all,
of which would be covered by insurance. In the opinion of management, none of
the existing litigation will have any material adverse effect on the Company.
 
PERSONAL INJURY AND PROPERTY DAMAGE LIABILITY CLAIMS
 
     Some of the operations of the Company are hazardous, and the Company has
experienced personal injury and property damage incidents. For claims prior to
1990, the Company maintains a reserve for the self-insured portion of its
personal injury and property damage coverage. Periodically, the Company
evaluates the adequacy of this reserve as compared with estimated settlements
for filed and anticipated claims. Estimated settlements for claims are based on
the Company's historical experience, type of claim, knowledge of the specific
circumstances of the claim and judgment of the possible effect that future
economic and legal factors might have on the ultimate settlement of the claim.
The Company believes that for claims prior to 1990, the accrued liability for
personal injury and property damage claims aggregating $2.4 million at December
31, 1997 is adequate.
 
     Beginning in 1990, the Company obtained workers' compensation and
third-party liability insurance under which its exposure to the risks covered by
those policies is significantly lower than under the pre-1990 coverage. The
Company provided $4.0 million, $3.5 million and $4.0 million in 1997, 1996 and
1995, respectively, as estimates of the aggregate uninsured portion of claims
for those years. The accrued liability for the uninsured portion of workers'
compensation and third-party claims incurred after 1989 was $10.2 million at
December 31, 1997, of which $0.5 million was held in a deposit account
accessible by the insurance

underwriters. In addition, at December 31, 1997 the Company had a $0.1 million
receivable related to claims payments made by the Company that are reimbursable
by insurance underwriters.
 
     In connection with the business acquisitions in 1995 and 1997 (see Note 3),
the Company assumed liabilities for the uninsured portions of workers'
compensation and third-party liability claims incurred prior to the date the
businesses were acquired. The accrued liability for such was $2.9 million at
December 31, 1997. Similar liabilities were not assumed for the 1996
acquisitions.
 
LEASE COMMITMENTS
 
     At December 31, 1997, the Company had a number of noncancelable long-term
operating leases, principally for yards and office space, rigs, computer
equipment, and a manufacturing and storage facility, with various expiration
dates. Future minimum net rentals under such leases aggregate $7.3 million for
1998; $6.6 million for 1999; $6.4 million for 2000; $6.0 million for 2001; $6.0
million for 2002; and $1.9 million thereafter. Rental expense incurred under
operating leases aggregated $13.0 million in 1997, $13.5 million in 1996, and
$13.3 million in 1995.
 
     The Company has an operating lease, effective through March 2003, for a
65-acre facility at San Angelo, Texas which it previously used for rig and
equipment manufacturing and storage. The annual lease payments, which are
included in future minimum net rentals above, are $2.2 million through March
1998 and $4.4 million thereafter for the remaining five years of the lease.
Effective October 1, 1994, the Company vacated this facility and subleased it in
its entirety under an operating sublease which expired in September 1997. The
sublease provided for minimum sublease payments of $0.5 million per year for
three years. In September 1988, the Company, anticipating that it would not be
able to fully utilize the facility for a period of years, accrued a $15.9
million liability for the expected underutilization. After September 1988, the
cost associated with the unutilized portion of the facility was charged against
this accrued liability, which as of the fourth quarter of 1994, had
substantially been used. For the remainder of the lease term, the Company did
not anticipate utilizing any of this facility in its future operations nor did
it expect to be able to sublease this facility to third parties for an amount
equivalent to the annual lease payments; therefore, in the fourth quarter of
1994 the Company recorded a provision for leasehold impairment of $23.6 million
(see Note 11). The provision recognized all future lease expense, net of
anticipated sublease income.
 
     In December 1993 the Company entered into sale/leaseback agreements with a
leasing company with respect to three offshore jackup rigs located in the Gulf
of Mexico, of which two rigs remain under lease. The leases, classified as
operating leases, have an aggregate annual lease rate of approximately $0.8
million per year. The Company has given notice to the leasing company of its
plans to purchase the two rigs for $2.3 million in December 1998. The sale and
leaseback agreements required the Company to place cash in a restricted
investment account which served as collateral for the leases; however, during
1997 the leasing company no longer required this collateral and the restricted
cash was returned to the Company.
 
8.  PENSION, POSTRETIREMENT AND POSTEMPLOYMENT BENEFITS
 
PENSION PLANS
 
     The Pool Company Retirement Income Plan, a defined benefit plan, covers
substantially all of the Company's domestic employees. The Company's policy is
to fund the minimum amount required by the Employee Retirement Income Security
Act of 1974. The benefits are based on years of service and the average of the
highest five consecutive years of compensation during the final ten years of
employment.
 
     Supplementary executive retirement plans provide certain management
employees with defined benefits in excess of those provided by the Retirement
Income Plan. The Company's policy is to fund annually, within 60 days following
the end of the plan year, the amount necessary to make plan assets sufficient to
pay each participant or beneficiary the benefits payable as of the close of that
plan year. The benefits are based on years

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     The Company accounts for postretirement benefits other than pensions based
upon Statement of Financial Accounting Standards No. 106, "Employers' Accounting
for Postretirement Benefits Other Than Pensions" ("SFAS 106") which requires the
Company to accrue the estimated cost of its retiree health care and life
insurance benefits during the years the employees provide services entitling
them to the benefits. In accordance with the provisions of SFAS 106, the Company
had elected to recognize the liability of approximately $2.9 million at the
January 1, 1993 implementation date over a period of twenty years. During 1997,
the Company amended its postretirement benefit plan by terminating
postretirement health care coverage for hourly employees who were not eligible
by December 31, 1997 and modifying the cost-sharing for eligible dependents. The
effect of this amendment was to reduce the Company's postretirement benefit
obligation by approximately $2.5 million.
 
     The following table sets forth certain information with respect to the
Company's postretirement benefits obligation at December 31:

</TABLE>
 
     The assumed health care cost trend rate used to measure the expected cost
of the benefits was 6.0% for 1997 and thereafter. If the assumed health care
cost trend rate were increased by one percent, the accumulated postretirement
benefit obligation as of December 31, 1997 would have increased by 11%, and the
aggregate of service and interest cost components for 1997 would have increased
17%. The assumed discount rate used in determining the accumulated
postretirement benefit obligation was 6.75% in 1997, 7.75% in 1996 and 7.25% in
1995.
 
POSTEMPLOYMENT BENEFITS
 
     The Company accounts for postemployment benefits based on Statement of
Financial Accounting Standards No. 112, "Employers' Accounting for
Postemployment Benefits," which requires the accrual of benefits provided after
employment but before retirement to former or inactive employees, their
beneficiaries, and covered dependents.

9.  TRANSACTIONS WITH ENSERCH
 
     ENSERCH (see Note 1) leases office space to the Company at negotiated rates
under an agreement that expires in December 2002. The total costs charged by
ENSERCH for such office space was $0.8 million in each of the three years ended
December 31, 1997.
 
     In connection with the Company becoming an independent public company,
ENSERCH and the Company entered into a contingent support agreement which
relates to ENSERCH's guarantee of the Company's lease obligations with respect
to the facility in San Angelo, Texas, through March 2003 ($22.3 million
outstanding at December 31, 1997). The Company is obligated to reimburse ENSERCH
for any amounts paid out under this guarantee.
 
     Certain oilfield services are performed for various affiliates and entities
managed by affiliates of ENSERCH at prices comparable to those received from
nonaffiliated customers. Revenues from the performance of those services,
amounted to $1.2 million in 1997, $2.3 million in 1996 and $1.8 million in 1995.
 
10. UNCONSOLIDATED AFFILIATES
 
     Some of the Company's operations are conducted through unconsolidated
affiliates, in which the Company held the following indicated ownership interest
at December 31, 1997: Pool Arabia, Ltd. -- 51% and Intairdril Oman
L.L.C. -- 49%. The Company charges its unconsolidated affiliates for the
provision of management services and, in some cases, financing and equipment
rental.
 
     The following table sets forth certain summarized financial information of
the Company's unconsolidated affiliates as shown by the financial statements of
the affiliates. Pool Arabia's 1996 net loss included a $2.3 million pretax loss
on disposal of two offshore jackup rigs sold to a third party. The loss on
disposal had no effect on the Company's equity in income from Pool Arabia
because the Company's basis in the rigs was lower than Pool Arabia's basis in
the rigs.

(a) Gross profit is computed as revenues less operating expenses (which excludes
    depreciation and amortization and selling, general and administrative
    expenses).
 
(b)  In October 1996, the Company acquired the 51% interest not already owned by
     the Company in Antah Drilling. Antah Drilling's results have been included
     in the accompanying financial statements since the date of such acquisition
     (see Note 3).
 
(c) In April 1996, the Company acquired the 51% interest not already owned by
    the Company in Pool Santana, Limited, a Trinidad corporation, the assets of
    which consisted primarily of a platform workover rig and its related
    equipment which were subsequently transferred to the Company's Gulf of
    Mexico operation.
 
     The Company's investment in its unconsolidated affiliates differs from its
ownership percentage of the affiliates' equity based on the financial statements
of the affiliates chiefly because of the allocation of the purchase price for
the 1990 purchase of ENSERCH's oilfield services business, unrecognized gains on
asset sales and other transactions as set forth below.

13.  NEW ACCOUNTING PRONOUNCEMENTS
 
     In June 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 130, "Reporting
Comprehensive Income." This statement establishes standards for reporting and
display of comprehensive income and its components. The Company plans to adopt
this statement in the first quarter of 1998. Its adoption is not expected to
have a material effect on the Company's financial statements.
 
     Also in June 1997, the FASB issued SFAS No. 131, "Disclosures about
Segments of an Enterprise and Related Information." This statement establishes

              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)
 
1. CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
 
     The condensed consolidated financial statements included in this report are
unaudited but in the opinion of management include all adjustments, consisting
only of normal recurring adjustments, necessary for a fair presentation of the
financial information for the periods indicated. All dollar amounts in the
tabulations in the notes to the financial statements are stated in thousands
unless otherwise indicated. Certain reclassifications have been made in the 1997
financial statements to conform with the 1998 presentation. Certain information
and footnote disclosures normally included in financial statements prepared in
accordance with generally accepted accounting principles have been condensed or
omitted.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
PRINCIPLES OF CONSOLIDATION
 
     The condensed consolidated financial statements include the financial
statements of Pool Energy Services Co. (the "Company") and all subsidiaries in
which a controlling interest is held. The Company uses the equity method to
account for affiliates in which it does not have control. In 1997, the Emerging
Issues Task Force of the Financial Accounting Standards Board (the "FASB")
reached a consensus on Issue 96-16, "Investor's Accounting for an Investee When
the Investor has a Majority of the Voting Interest but the Minority Shareholder
or Shareholders Have Certain Approval or Veto Rights" ("EITF 96-16"). EITF
96-16, which is effective for fiscal years ended after December 15, 1998, sets
forth new criteria for evaluating whether or not the rights of the minority
shareholder are sufficient to overcome the presumption that all majority-owned
investees should be consolidated. After reviewing the guidance provided by EITF
96-16 with respect to what constitutes "control," together with the specific
rights of the minority shareholder of Pool International Argentina S.A.
("PIASA") in the shareholders' agreement, the Company concluded that it could
not clearly overcome the presumption that certain of the rights of the minority
shareholder were substantive participating rights. Specific reasons for such are
as follows: (i) the shareholders' agreement between the Company and the minority
shareholder of PIASA requires the unanimous consent of PIASA's Board of
Directors for the approval of the annual capital and operating budgets of PIASA
and the making of any significant revisions to such budgets (two of the five
Board of Directors of PIASA are appointed by the minority shareholder) and (ii)
the shareholders' agreement requires the unanimous consent of PIASA's Board of
Directors for the approval of the purchase, leasing, chartering or other
acquisition of property or assets, not already approved in the annual capital
budget, which exceed $50,000. The minority rights identified above as
participating rights are significant in the ordinary course of PIASA's business;
accordingly, the Company concluded that it should change from consolidation
accounting to the equity method for its 51% investment in PIASA, which it did
effective January 1, 1998. Prior to January 1, 1998, 100% of PIASA's assets,
liabilities, results of operations and cash flows were included in the Company's
respective consolidated totals. The change in method of accounting had no effect
on the Company's consolidated net income for the three months ended March 31,

</TABLE>
 
DEFERRED COSTS
 
     Deferred costs consist primarily of drydocking expenses incurred in
conjunction with marine inspections of offshore support vessels and debt
financing costs. Drydocking expenses are capitalized and amortized on a
straight-line basis over a period normally not to exceed 30 months. Debt
financing costs are amortized over the terms of the related borrowings. The
major components of deferred costs are unamortized deferred drydocking expenses
of $5.3 million at March 31, 1998 and unamortized debt financing costs of $4.9
million at March 31, 1998.
 
DEFERRED RIG MOBILIZATION
 
     In connection with its rig contracts, the Company may receive lump sum fees
for the mobilization of equipment. The net amount of the lump sum fees received
and the mobilization expenses incurred are deferred and amortized over the term
of the contract.
 
3. EARNINGS PER SHARE
 
     The following tables set forth the amounts used in computing earnings per
share ("EPS") and the weighted average number of shares of dilutive potential
common stock for the quarters ended March 31, 1998 and 1997.

4. LONG-TERM DEBT AND LINE OF CREDIT
 
SENIOR SUBORDINATED NOTES
 
     On March 31, 1998, the Company completed a private placement of 8 5/8%
senior subordinated notes due 2008 in the aggregate principal amount of $150
million (the "Notes"). The net proceeds from the sale of the Notes were used to
fund the cash portion of the purchase price for Sea Mar, Inc. ("Sea Mar") (see
Note 5), to repay the existing debt of Sea Mar and to reduce the outstanding
balance under the Company's three-year $180 million syndicated bank credit
agreement (the "Credit Agreement"). The Notes are redeemable at the option of
the Company, in whole or in part, at any time on or after April 1, 2003 at a
redemption price equal to 104.313% of the principal amount thereof, plus accrued
interest, declining ratably to par on April 1, 2006. The Company may also redeem
up to 35% of the aggregate principal amount of the Notes at its option, from
time to time on or prior to April 1, 2001, at a redemption price equal to
108.625% of the principal amount thereof, plus accrued interest, with the net
proceeds of one or more equity offerings of the Company's common stock.
 
     The Notes are general unsecured obligations of the Company subordinated in
right of payment to all existing and future senior indebtedness of the Company
and are unconditionally guaranteed, jointly and severally, by all of the
Company's wholly-owned subsidiaries that are incorporated or organized in the
United States (the "Subsidiary Guarantors"). The Notes contain certain covenants
that, among other things, limit the ability of the Company and the Subsidiary
Guarantors to incur additional indebtedness, issue capital stock of Subsidiary
Guarantors, pay dividends or make other restricted payments, incur liens, enter
into certain transactions with affiliates, enter into certain mergers or
consolidations or sell all or substantially all of the assets of the Company and
its subsidiaries. See Note 8 for the unaudited condensed consolidating financial
information for Pool Energy Services Co., the Subsidiary Guarantors and the
Non-Guarantor Subsidiaries as of and for the quarters ended March 31, 1998 and
1997.
 
CREDIT AGREEMENT
 
     In March 1998, simultaneously with the issuance of the Notes and the
closing of the Sea Mar Acquisition, the Company executed an amendment to the
Credit Agreement to increase maximum availability thereunder from $130 million
to $180 million, including up to $15 million that may be used to support letters
of credit. At March 31, 1998 the Company had drawn $5.0 million in cash under
the Credit Agreement, and

      NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
an additional $11.6 million was being utilized to support the issuance of
letters of credit, primarily related to insurance obligations.
 
     Borrowings under the Credit Agreement bear interest, at the Company's
option, at either (i) the Base Rate (defined as the higher of the administrative
agent bank's prime lending rate or 1/2 of 1% in excess of the federal funds
rate) plus a margin ranging from zero to .50%, or (ii) the Eurodollar Rate
(equivalent to the London Interbank Offered Rate plus a margin ranging from 1%
to 1.75% with the Company's option of a one-, two-, three- or six-month interest
period). The applicable margin for each interest option depends on the Company's
leverage ratio for the fiscal quarter preceding the interest period; however,
through September 1998, the applicable Eurodollar margin shall not be less than
1.50%. Based upon the Company's leverage ratio at March 31, 1998, the applicable
Eurodollar margin would have been 1.00%. The Credit Agreement will mature on
October 2, 2000 and is subject to one-year extensions at the discretion of the
lenders. Revolving loans issued under the Credit Agreement are prepayable at any
time and are due at expiration on October 2, 2000. The Credit Agreement imposes
certain financial covenants, including ones requiring the maintenance of a
minimum net worth, a minimum interest coverage ratio, a minimum fixed charge
coverage ratio, a maximum leverage ratio and a maximum debt-to-equity ratio. It
also imposes certain other restrictions, including ones related to liens, other
indebtedness, asset sales, investments, acquisitions or mergers and the payment
of dividends. Advances under the Credit Agreement are secured by a pledge of 66%
of the capital stock of certain of the Company's foreign subsidiaries.
 
     The Company incurred $4.2 million and $0.5 million of debt financing costs
during the first three months of 1998 in connection with the Notes offering and
the Credit Agreement, respectively.
 
5. ACQUISITION OF SEA MAR, INC.
 
     On March 31, 1998, the Company acquired all of the outstanding capital
stock of Sea Mar, a privately owned Louisiana-based offshore support vessel
company with operations primarily in the Gulf of Mexico, for approximately $75.9
million in cash (including an estimated $14.7 million in post-closing purchase
price adjustments) and 1,538,462 shares of the Company's common stock (the "Sea
Mar Acquisition"). In addition, the Company agreed to pay additional cash
consideration contingent upon Sea Mar exceeding certain financial targets for
the fiscal years ending December 31, 1998 and 1999, up to a maximum of $10
million in each year.
 
     The acquisition was accounted for under the purchase method, and Sea Mar's
results of operations will be included in the Company's consolidated financial
statements from the date of the acquisition. The purchase price was allocated
based on preliminary estimates of the fair market value of the assets acquired
and the liabilities assumed at the date of acquisition. The purchase price
allocation is subject to adjustment as additional information becomes available
and is evaluated. The primary items that may be subject to further adjustment
are fair value assessments of property, plant and equipment and reserves for
income taxes. This preliminary purchase price allocation resulted in goodwill of
approximately $21.5 million, which is being amortized on a straight-line basis
over 25 years. The purchase price paid at closing is subject to adjustment to
the extent that the shareholder's equity of Sea Mar at March 31, 1998 exceeded
the amount at August 31, 1997. This purchase price adjustment, which is expected
to be paid by mid-1998, is estimated to be $14.7 million and has been accrued.

     Sea Mar has a contract with a marine shipbuilder for the construction of
ten offshore support vessels at an estimated aggregate cost of $77.6 million,
net of deposits. These new vessels are scheduled to be delivered between late
1998 and early 2000.
 
     The following unaudited pro forma summary of financial information presents
the Company's consolidated results of operations as if the Sea Mar Acquisition
had occurred at the beginning of the periods indicated, after including the
impact of certain adjustments, such as: additional depreciation expense,
amortization of goodwill, amortization of the portion of the purchase price
allocated to a noncompete agreement, reduction of gains on sales due to the
purchase price allocation, increased interest expense and amortization of the
related debt financing costs associated with the $150 million Notes, reduction
of interest expense for the repayment of existing Sea Mar debt and repayments on
the Credit Agreement and related income tax effects thereon.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Shareholder
of Sea Mar, Inc.:
 
We have audited the accompanying consolidated balance sheets 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 balance sheets 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.

                   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 -- (CONTINUED)
 
  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.

administrative expenses in the Company's statements of operations.

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

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
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.

                     INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Pursuant to Article 2.02-1 of the Texas Business Corporation Act, Article
XIII of the bylaws of the Company authorizes the Company to indemnify any person
who (1) is or was a director, officer, employee or agent of the Company or (2)
while a director, officer, employee or agent of the Company, or was serving at
the request of the Company as a director, officer, partner, venturer,
proprietor, trustee, employee, agent or similar functionary of another foreign
or domestic corporation, partnership, joint venture, sole proprietorship, trust,
employee benefit plan or other enterprise, to the fullest extent that a
corporation may or is required to grant indemnification to a director under the
Texas Business Corporation Act. The Company may indemnify any person to such
further extent as permitted by law.
 
     The Company's Articles of Incorporation limit the personal liability of
directors to the fullest extent permitted by Texas law. Specifically, a director
of the Company will not be personally liable to the Company or its shareholders
for monetary damages for an act or omission in the director's capacity as a
director, except for liability: (i) for a breach of the director's duty of
loyalty to the Company or its shareholders, (ii) for an act or omission not in
good faith or that involves intentional misconduct or a knowing violation of the
law, (iii) for a transaction from which the director derived an improper
personal benefit, whether or not the benefit resulted from an action taken
within the scope of the director's office, or (iv) an act or omission for which
the liability of the director is expressly provided by an applicable statute,
such as a corporation's unlawful stock repurchase or payment of a dividend. This
provision is intended to afford directors additional protection from, and limit
their potential liability for, suits alleging a breach of the duty of care by a
director. The Company believes that this provision will assist in its securing
and retaining the services of directors who are not employees of the Company. As
a result of the inclusion of this provision, shareholders may be unable to
recover monetary damages against directors for actions taken by them that
constitute negligence or gross negligence or that are in violation of their
fiduciary duties, although it may be possible to obtain injunctive or other
equitable relief with respect to such actions. If equitable remedies are found
not to be available to shareholders for any particular case, shareholders may
not have an effective remedy against the challenged conduct.

(*) Filed herewith
 
     (b) Financial Statement Schedules
 
     All schedules for which provision has been made in the applicable
accounting regulations of the Commission are either not required under the
related instructions, are not applicable (and therefore have been omitted), or
the required disclosures are contained in the financial statements included
herein.
 
ITEM 22. UNDERTAKINGS
 
     (a) Each of the undersigned registrants hereby undertakes:
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.
 
     (b) Each of the undersigned registrants hereby undertakes:
 
          (1) To respond to requests for information that is incorporated by
     reference into the Prospectus pursuant to Item 4, 10(b), 11 or 13 of Form
     S-4, within one business day of receipt of such request, and to send the
     incorporated documents by first class mail or other equally prompt means.
     This includes information contained in documents filed subsequent to the
     effective date of the Registration Statement through the date of responding
     to the request.
 
          (2) To supply by means of a post-effective amendment all information
     concerning a transaction, and the company being acquired involved therein,
     that was not the subject of and included in the registration statement when
     it became effective.

                   ARTICLES OF AMENDMENT OF THE SHAREHOLDERS
                      TO THE ARTICLES OF INCORPORATION OF
                            POOL ENERGY SERVICES CO.



         Pursuant to the provisions of Article 4.04 of the Texas Business
Corporation Act, the undersigned corporation adopts the following Articles of
Amendment to its Articles of Incorporation:

         ARTICLE ONE.     The name of the corporation is Pool Energy Services
Co.

         ARTICLE TWO.     The following amendment to the Articles of
Incorporation was adopted by the shareholders of the corporation on December
20, 1988:

         The Articles of Incorporation of the corporation are amended by
revising Article Four in its entirety to read as follows:

                                 "ARTICLE FOUR

         "The total number of shares that the corporation is authorized to
issue is 25,049,000 shares, consisting of 25,000,000 Common shares, each of
which shall be without par value, and 49,000 Preferred shares having a par
value of Ten Dollars ($10.00) per share.

         "1.     The holders of shares of Preferred stock shall be entitled to
receive dividends at a rate equal to the stated "prime rate" per annum of Texas
Commerce Bank, Houston, that is in effect at the close of business three (3)
business days prior to the date on which dividends are to be paid, plus an
additional two percent (2%) per annum.  The "prime rate" per annum of Texas
Commerce Bank, Houston, shall be the rate of interest per annum and thereafter
entered into the minutes of said bank.  Said dividends shall be paid quarterly
when and as declared by the board of directors on the first days of March,
June, September and December.  Said dividends shall accrue from the date of
issuance of the Preferred shares and shall be deemed to accrue from day to day
whether or not earned or declared.  Such dividends shall be cumulative, and if
for any quarterly dividend period dividends at the rate set forth above shall
not have been paid or declared or set apart therefor, the amount of the
deficiency shall be fully paid or declared and set apart for payment, but
without interest, before any distribution, whether in the form of dividends or
otherwise, shall be declared or paid upon or set apart for the Common shares.
The amount of dividends per share payable for each quarterly dividend period
shall be computed by dividing the dividend rate for such dividend period by
four and applying such rate against the par value of the Preferred shares.
<PAGE>   6
         "2.     The Preferred shares shall be redeemable at the option of, and
at the discretion of the board of directors, in whole but not in part, at the
par value thereof, together with all accrued and unpaid dividends thereon to
the date of such redemption to the extent that funds of the corporation are
lawfully available therefor.  The redemption of Preferred shares shall be
effected in accordance with the Provisions for Redemption as set forth int he
Texas Business Corporation Act.

         "3.     At any time beginning 90 days following the effective date of
any registration statement ("Registration Statement") as filed with the United
States Securities and Exchange Commission, pursuant to which the Common shares
of this corporation are first issued and sold to the public and ending at the
close of business on the day before the date of redemption stated in any
redemption notice, the holder of Preferred shares, on surrender of his
certificates for such Preferred shares at the office of the corporation, duly
indorsed and delivered to the corporation together with his written notice of
intention to convert, shall be entitled to convert the shares of Preferred
stock into that number of fully paid and nonassessable shares of Common stock
obtained by dividing the aggregate par value of the Preferred shares to be
converted by an amount equal to one hundred and twenty percent (120%) of the
Subscription Price, as defined in the Registration Statement.  Should any
increases or reduction in the number of outstanding shares of Common stock
occur after the date of the first issuance of the Preferred stock by reason of
any split, share dividend, merger, consolidation, or other capital change or
reorganization affecting the number of outstanding Common shares, the number of
Common shares to be issued to the holder of the Preferred shares must be fairly
and equitably adjusted by appropriate amendment of this subparagraph so as
fairly and equitably to preserve as far as reasonably possible the original
conversion rights of all the Preferred shares.  Any amendment and adjustment
necessitated by any increases or reduction in the number of the outstanding
shares of Common stock must be accomplished before any notice or redemption may
be given to the Preferred shareholders.

         "The corporation shall at all times reserve and keep available, out of
its authorized but unissued Common shares, solely for the purpose of conversion
of its Preferred shares, such number of Common shares as shall be sufficient to
effect the conversion of all Preferred shares from time to time outstanding,
and the corporation shall obtain and keep in force such permits as may be
required in order to enable the corporation lawfully to issue and deliver such
number of Common shares.  On conversion, no fractional Common share shall be
issued, but in lieu thereof the corporation shall pay therefor in cash.


                                      2
<PAGE>   7
         "4.     In the event of any voluntary of involuntary liquidation,
dissolution or winding up of the corporation, the holders of the Preferred
shares shall receive an amount equal to the par value of such shares, plus all
accrued and unpaid dividends whether or not earned or declared before any
distribution shall be made to the holders of the Common shares.

         "5.     In the event the closing price of the Common shares, as
reported on a national stock exchange, or the closing bid price as reported in
the over-the-counter market, shall be less than eighty percent (80%) of the
Subscription Price, as defined in the Registration Statement, for any ten (10)
days during a consecutive thirty (30)-day period, the holder(s) of all of the
issued and outstanding Preferred shares may, at its or their option, require
the corporation to purchase all, but not less than all, of such Preferred
shares as follows:

         "a.     The purchase price shall be Ten Dollars ($10) per share, plus
                 all accrued and unpaid dividends thereon to the date of such
                 purchase.

         "b.     Such right shall be exercised, if at all, by the delivery of
                 written notice thereof, signed by all holders of the Preferred
                 shares, to the Treasurer of the corporation at the offices of
                 the corporation in Houston, Texas, not less than thirty (30)
                 nor more than sixty (60) days prior to the date such right is
                 to be exercised.  Payment of the purchase price shall  be made
                 in cash or by certified or cashier's check that shall be
                 delivered upon surrender of certificates, duly indorsed,
                 representing all of the issued and outstanding shares of
                 Preferred stock.

         "c.     If the obligation to purchase shares hereunder shall be
                 prohibited or restricted by any provision of the laws of the
                 State of Texas or the Articles of Incorporation or any debt
                 instrument of the corporation, such obligation shall be

                       TO THE ARTICLES OF INCORPORATION OF
                            POOL ENERGY SERVICES CO.



         Pursuant to the provisions of Article 4.04 of the Texas Business
Corporation Act, the undersigned corporation adopts the following Articles of
Amendment to its Articles of Incorporation:

         ARTICLE ONE. The name of the corporation is Pool Energy Services Co.

         ARTICLE TWO. The following amendments to the Articles of Incorporation
were adopted by the shareholders of the corporation on April 11, 1990.

         The Articles of Incorporation of the corporation are amended by
revising ARTICLE FOUR in its entirety to read as follows:

                                  ARTICLE FOUR

         The total number of shares that the corporation is authorized to issue
is 25,001,000 shares, consisting of 25,000,000 shares of common stock, without
par value ("Common Stock"), and 1,000 share of preferred stock, without par
value (Preferred Stock).

         The following is a statement of the designation and the powers,
preferences, relative rights and privileges and the restrictions, limitations
and qualifications, of the classes of stock of the corporation.

                           Section I. Preferred Stock

         (1) Dividends. The holders of the Preferred Stock shall not be entitled
to receive dividends thereon.

         (2) Redemption. The Preferred Stock is not redeemable.

         (3) Voting Rights of Preferred Stock. Except as otherwise required by
law and as set forth below in this subparagraph (3), holders of the Preferred
Stock shall not be entitled to vote on any matter to be voted on by holders of
the Common Stock.

                  (a) Whenever and so long as ENSERCH Corporation or any of its
         affiliates (collectively "ENSERCH") is the holder of all of the
         outstanding shares of Preferred Stock, ENSERCH, voting separately as a
         class, shall be entitled, at any annual meeting of the shareholders or
         special meeting held in place hereof, to elect two directors to the
         Board of Directors of the corporation.


<PAGE>   11




                  (b) Whenever and so long as ENSERCH is the holder of all of
         the outstanding shares of Preferred Stock and an Event of Default as
         defined in Section 21 (a "Default") of that certain Contingent Support
         Agreement between the corporation and ENSERCH dated on or about April
         13, 1990 ("Contingent Support Agreement") shall have occurred and be
         continuing, then and in such event, the authorized number of directors
         of the corporation shall be increased and ENSERCH, voting separately as
         a class, shall be entitled, at any annual meeting of the shareholders
         or special meeting held in place thereof, or in lieu of a meeting by
         written consent of ENSERCH, to elect that number of directors just
         constituting a majority of the Board of Directors; provided, however,
         any designee of ENSERCH serving on the Board of Directors of the
         corporation pursuant to subparagraph (a) above shall be deemed a
         director representing the Preferred Stock under this subparagraph (b),
         and further provided, that none of the directors required to be added
         pursuant to subparagraph (b) (the "Additional Directors") shall be an
         officer, director, or employee of ENSERCH or an affiliate thereof. Such
         right of ENSERCH to elect Additional Directors may be exercised until
         all Defaults under the Contingent Support Agreement shall have been
         cured or waived, and when so cured or waived, then the right of ENSERCH
         to elect such Additional Directors under this subparagraph (b) shall
         cease, but subject always to the same provisions for the vesting of
         such voting rights in the case of any such future Default or Defaults.
         At any time after such right to elect Additional Directors shall have
         so vested in ENSERCH, the Secretary of the corporation, upon the
         written request of ENSERCH addressed to him at the principal office of
         the corporation, shall call a special meeting of the holders of the
         Preferred Stock for the election of the Additional Directors, to be
         held within forty (40) days after delivery of such request and at the
         place and upon the notice provided by law and in the bylaws for the
         holding of meetings of shareholders; provided, however, that the
         Secretary shall not be required to call such special meeting in the
         case of any such request received less than ninety (90) days before the
         date fixed for the next ensuing annual meeting of shareholders. No such
         special meeting and no adjournment thereof shall be held on a date less
         than thirty (30) days before the annual meeting of the shareholders or
         special meeting held in place thereof. At any annual meting or special
         meeting called for the election of Additional Directors, the absence of
         a quorum of the holders of the Common Stock shall not invalidate or
         otherwise prevent the conduct of the meeting for the purpose of the
         election of the Additional Directors. The Additional Directors so
         elected shall serve until the next annual meeting or until their
         respective successors shall be elected and shall qualify; provided,
         however, that whenever ENSERCH shall be divested of voting power as
         above


<PAGE>   12



         provided, the terms of office of all persons elected as Additional
         Directors under this subparagraph (b) shall forthwith terminate, an the
         number of the Board of Directors shall be reduced accordingly. Anything
         in this subparagraph (b) to the contrary notwithstanding, ENSERCH, so
         long as it owns all of the outstanding shares of Preferred Stock, may,
         at any time a Default exists, waive any notice and call of meeting and
         elect the Additional Directors by written consent in lieu of a meeting.

                  (c) In the event of the resignation, death or removal of a
         director elected pursuant to subparagraphs (a) or (b) above (except for
         directors whose terms of office terminate by the curing or waiver of
         Defaults as provided in subparagraph (b) above), the vacancy or
         vacancies shall be filled by a majority vote of the directors then in
         office. Any director so elected may be removed from office by vote of
         ENSERCH, as long as ENSERCH owns all of the shares of Preferred Stock,
         at a special meeting of the holders of the Preferred Stock that may be
         called on the written request of ENSERCH, as holder of all of the
         shares of Preferred Stock. The Secretary of the corporation shall, in
         any event, within ten (10) days after delivery to the corporation at
         its principal office of a request to such effect signed by ENSERCH, as
         holder of all of the shares of Preferred Stock, call a special meting
         for such purpose to be held within forty (40) days after delivery of
         such request; provided, however, that the Secretary shall not be
         required to call such a special meeting in the case of any such request
         received less than ninety (90) days before the date fixed for the next
         ensuing annual meeting of shareholders. Anything in this subparagraph
         (c) to the contrary not withstanding, ENSERCH, as long as it owns all
         of the outstanding shares of Preferred Stock, may at any time remove a
         director who was selected by the majority vote of the board to fill a
         vacancy as provided in this subparagraph (c) and/or elect a director or
         directors to fill a vacancy or vacancies by written consent in lieu of
         a meeting and thereby waive any notice and call of meeting.

                  (d) So long as any shares of the Preferred Stock are
         outstanding, the corporation shall not, without the affirmative vote of
         the holders of a majority of the Preferred Stock, adopt an amendment to
         these Articles of Incorporation if such amendment would (i) authorize
         or create, or increase the authorized amount of, any class of stock
         which is entitled to voting rights inconsistent with the outstanding
         Preferred Stock, (ii) increase the authorized number of shares of
         Preferred Stock, (iii) change any of the rights or preferences of the
         then outstanding Preferred Stock or (iv) materially alter any other
         provisions of the outstanding Preferred Stock or the Common Stock of
         the corporation.



<PAGE>   13



                  Each share of the Preferred stock shall entitle the holder
         thereof to one vote on all matters on which holders of Preferred Stock
         are entitled to vote.

         (4) Priority of Preferred Stock. In the event of any liquidation,
dissolution or winding up of the affairs of the corporation, whether voluntary
or otherwise, after payment or provision for payment of debts and other
liabilities of the corporation, the holders of the Preferred Stock shall be
entitled to receive out of the remaining assets of the corporation the amount of
One Dollar ($1.00) in cash for each share of Preferred Stock before any
distribution or payment shall be made to the holders of any other series of
Preferred Stock, any other class of stock ranking junior to the Preferred Stock,
or the Common Stock of the Corporation. After payment to the holders of the
Preferred Stock of the full preferential amounts distributable to them as
aforesaid, the holders of the Preferred Stock will have no other rights or
claims to any of the remaining assets of the Company either upon the
distribution of such assets or upon dissolution, liquidation or winding up.

         Neither the consolidation nor merger of the corporation with or into
any other corporation, nor any sale, lease, exchange or conveyance of all or any
part of the property, assets or business of the corporation, nor any
liquidation, dissolution or winding up occurring substantially concurrently with
any such sale, lease, exchange of conveyance, shall be deemed to be a voluntary
liquidation, dissolution or winding up of the corporation within the meaning of
this Section (4).

                            Section II. Common Stock

         (1) Dividends. Subject to the preferential rights, if any, of the
holders of Preferred Stock, the holders of Common Stock shall be entitled to
receive such dividends, if any, as may be declared from time to time by the
Board of Directors from funds legally available therefor.

         (2) Priority of Common Stock. After distribution in full of the
preferential amount, if any, to be distributed to the holders of Preferred Stock
in the event of any liquidation, dissolution or winding up of the affairs of the
corporation, whether voluntary or involuntary, the holders of the Common Stock
shall be entitled to receive all the remaining assets of the corporation,
tangible and intangible, of whatever kind available for distribution to
shareholders, ratably in proportion to the number of shares of the Common Stock
held by each.

         (3) Voting Rights. Except as may otherwise be required by law or the
Articles of Incorporation of the corporation, each holder of Common Stock shall
have one vote in respect of each share of Common Stock held by such holder of
each matter voted upon by the stockholders.

         of any class of the corporation now or hereafter to be authorized, or
         any notes, debentures, bonds, or other securities convertible into or
         carrying any right, option or warrant to subscribe to or acquire shares
         of any class now or hereafter to be authorized, whether or not the
         issuance of any such shares, or such notes, debentures, bonds or other
         securities, would adversely affect the dividends or voting rights of
         such shareholders, and the Board of Directors may issue or authorize

         other securities convertible into or carrying rights, options or

meeting.  If mailed, such notice shall be deemed to be delivered when deposited

prepaid.

                 Section 5.  The officer or agent having charge of the stock
transfer books for shares of the corporation shall make, at least ten (10) days
before each meeting of shareholders, a complete list of the shareholders
entitled to vote at such meeting or any adjournment thereof, arranged in
alphabetical order, with the address of and the number of shares held by each,
which list, for a period of ten (10) days prior to such meeting, shall be kept
on file at the registered office of the corporation and shall be subject to
inspection by any shareholder at any time during usual business hours.  Such
list shall also be produced and kept open at the time and place of the meeting
and shall be subject to the inspection of any shareholder during the whole time
of the meeting.  The original stock transfer books shall be prima-facie

                 Section 6.  The holders of a majority of the shares issued and

                                       3
<PAGE>   4
entitled to vote thereat, present in person or represented by proxy shall have
power to adjourn the meeting from time to time, without notice other than
announcement at the meeting, until a quorum shall be present or represented.

business may be transacted which might have been transacted at the meeting as
originally notified.

                 Section 7.  Each outstanding share, of any class, shall be

                 Section 9.  When a quorum is present at any meeting, the vote
of the holders of a majority of the shares having voting power present in
person or represented by proxy shall decide any question brought before such
meeting, unless the question is one upon which, by express provision of the
statutes or of the Articles of Incorporation or of these Bylaws, a different
vote is required, in which case such express provision shall govern and control
the decision of such question.  The shareholders present at a duly organized
meeting may continue to transact business until adjournment, notwithstanding
the withdrawal of enough shareholders to leave less than a quorum.

                 Section 10.  The Chairman shall preside at all meetings of the
shareholders.  In his absence, an officer of the corporation designated by the
Board of Directors shall preside and perform the duties of the Chairman at such
meeting.  He shall appoint two inspectors of voting to serve at each such
meeting.  Before acting at any meeting the inspectors shall be sworn faithfully
to execute their duties with strict impartiality and according to the best of
their ability.  The inspectors shall determine the number of shares
outstanding, the voting power of each, the shares represented at the meeting,
the existence of a quorum, the qualification of voters, the authenticity,
validity and effect of proxies, receive votes and ballots, hear and determine
all challenges and questions in any way arising in connection with the vote,
count and tabulate all votes and determine and announce the result of the
voting.

                 Section 11.  At an annual meeting of the shareholders, only
such business shall be conducted as shall have been properly brought before the
meeting.  To be properly brought before an annual meeting, business must be
specified in the notice of meeting (or any supplement thereto) given by or at
the direction of the Board, otherwise properly brought before the meeting by or
at the direction of the Board, or otherwise properly brought before the meeting
by a shareholder.  In addition to any other applicable requirements, for
business to be properly brought before an annual meeting by a shareholder, the
shareholder must have given timely notice thereof in writing to the Corporate
Secretary.  To be timely, a shareholder's notice must be delivered to or mailed
and received at the principal executive offices of the corporation, not less
than fifty (50) days nor more than seventy-five (75) days prior to the meeting;
provided, however, that in the event that less than sixty-five (65) days'
notice or prior public disclosure of the date of the meeting is given or made
to shareholders, notice by the shareholder to be timely must be so received not
later than the close of business on the 15th day following the day on which
such notice of the date of the annual meeting was mailed or such public
disclosure was made.  A shareholder's notice to the Corporate Secretary shall
set forth as to each matter the shareholder proposes to bring before the annual
meeting (i) a brief description of the business desired to be brought before
the annual meeting and the reasons for conducting such business at the annual
meeting, (ii)





                                       6
<PAGE>   7
the name and record address of the shareholder proposing such business, (iii)
the class and number of shares of the corporation which are beneficially owned
by the shareholder, and (iv) any material interest of the shareholder in such
business.

                 Notwithstanding anything in the Bylaws to the contrary, no
business shall be conducted at the annual meeting except in accordance with the
procedures set forth in this Section 11; provided, however, that nothing in
this Section 11 shall be deemed to preclude discussion by any shareholder of
any business properly brought before the annual meeting in accordance with said
procedure.

                 The Chairman of an annual meeting shall, if the facts warrant,
determine and declare to the meeting that business was not properly brought
before the meeting in accordance with the provisions of this Section 11, and if
he should so determine, he shall so declare to the meeting and any such
business not properly brought before the meeting shall not be transacted.

                 Section 12.  Only persons who are nominated in accordance with
the following procedures shall be eligible for election as Directors.
Nominations of persons for election to the Board of the corporation may be made
at a meeting of shareholders by or at the direction of the Board of Directors
by any nominating committee or person appointed by the Board or by any
shareholder of the Corporation entitled to vote for the election of Directors
at the meeting who complies with the notice procedures set forth in this
Section 12.  Such nominations, other





                                       7
<PAGE>   8
than those made by or at the direction of the Board, shall be made pursuant to
timely notice in writing to the Corporate Secretary.  To be timely, a
shareholder's notice shall be delivered to or mailed and received at the
principal executive offices of the corporation not less than fifty (50) days
nor more than seventy-five (75) days prior to the meeting; provided, however,
that in the event that less than sixty-five (65) days' notice or prior public
disclosure of the date of the meeting is given or made to shareholders, notice
by the shareholder to be timely must be so received not later than the close of
business on the 15th day following the day on which such notice of the date of
the meeting was mailed or such public disclosure was made.  Such shareholder's
notice to the Corporate Secretary shall set forth (a) as to each person whom
the shareholder proposes to nominate for election or re-election as a Director,
(i) the name, age, business address and residence address of the person, (ii)
the principal occupation or employment of the person, (iii) the class and
number of shares of capital stock of the corporation which are beneficially
owned by the person, and (iv) any other information relating to the person that
is required to be disclosed in solicitations for proxies for election of
Directors pursuant to Rule 14a under the Securities Exchange Act of 1934 as
amended; and (b) as to the shareholder giving the notice (i) the name and
record address of shareholder and (ii) the class and number of shares of
capital stock of the corporation which are beneficially owned by the
shareholder.  The corporation may





                                       8
<PAGE>   9
require any proposed nominee to furnish such other information as may
reasonably be required by the corporation to determine the eligibility of such
proposed nominee to serve as Director of the corporation.  No person shall be
eligible for election as a Director of the corporation unless nominated in
accordance with the procedures set forth herein.

                 The Chairman of the meeting shall, if the facts warrant,
determine and declare to the meeting that a nomination was not made in
accordance with the foregoing procedure, and if he should so determine, he
shall so declare to the meeting and the defective nomination shall be
disregarded.

                 Section 13.  Any action required by law to be taken at a
meeting of the shareholders, or any action which may be taken at a meeting of
the shareholders, may be taken without a meeting if a consent in writing
setting forth the action so taken shall be signed by all of the shareholders
entitled to vote with respect to the subject thereof.

                 Section 14.  Upon compliance with the notice requirements of
this Article or waiver of notice, a meeting of shareholders may be conducted by
means of conference telephone or similar communications equipment if all person
participating in the meeting can hear each other.

                                  ARTICLE III

                                   DIRECTORS

                 Section 1.  The business and affairs of the corporation shall
be managed by its Board of Directors who may exercise all such powers of the
corporation and do all such lawful acts and things as are not by statute or by
the Articles of Incorporation or by these Bylaws directed or required to be
exercised or done by the shareholders.

                 Section 2.  The Board of Directors shall consist of at least
two, but not more than ten Directors, which number shall be determined by the
Directors from time to time, subject to the automatic reduction provisions of
Section 4 of this Article III.  A person shall be ineligible to be a Director
of the corporation after the date of the annual meeting of shareholders of the
corporation in the year in which such person's seventy-seventh birthday occurs,
provided, however, that commencing as of the date of the annual meeting of
shareholders to be held in 1995, a person shall be ineligible to be elected as
a Director of the corporation if he or she is seventy years of age or older.
Directors need not be shareholders or residents of the State of Texas.  The
Directors shall be divided into three classes, designated Class I, Class II and
Class III.  The initial term for directors in Class I shall expire at the
annual meeting of shareholders to be held in 1995; the initial term for
Directors in Class II shall expire at the annual meeting of shareholders to be
held in 1996; and the initial term for Directors in Class III





                                       10
<PAGE>   11
shall expire at the annual meeting of shareholders to be held in 1997.  Each
class of Directors shall consist, as nearly as possible, of one-third of the
total number of Directors constituting the entire Board of Directors.

         At the expiration of the initial term of each class of Directors, and
of each succeeding term of each class, each class of Directors shall be elected
to serve until the annual meeting of shareholders held three years from such
expiration and until their successors are elected and qualified or until their
earlier death, resignation, removal or retirement.  Any increase or decrease in
the number of Directors constituting the Board shall be apportioned among the
classes so as to maintain the number of Directors in each class as nearly as
possible to one-third of the total number of Directors as so adjusted.

                 Section 3.  Any Director may resign at any time either by oral
tender of resignation at any meeting of the Board of Directors or by giving
written notice thereof to the Corporate Secretary.  Resignations shall take
effect when tendered or at the time specified in the tender and, unless
otherwise specified, the acceptance of a resignation shall not be necessary to
make it effective.

                 Section 4.  Any director may be removed from office only at a
meeting of shareholders called expressly for that purpose by the affirmative
vote of the holders of at least two-thirds of the shares then entitled to vote
at an election of directors, and only for cause.  Except as may otherwise be





                                       11
<PAGE>   12
provided by law, cause for removal shall be construed to exist only if the
director whose removal is proposed has been convicted of a felony by a court of
competent jurisdiction and such conviction is no longer subject to direct
appeal, has been adjudged by a court of competent jurisdiction to be liable for
negligence or misconduct in the performance of his duties to the corporation in
a matter of substantial importance to the corporation and such adjudication is
no longer subject to direct appeal, or has been declared of unsound mind by
order of court.  Whenever any director shall cease to serve due to death,
resignation, removal, or for any other reason except for retirement which
occurs on the date of an annual meeting of shareholders, the number of
directors constituting the Board of Directors shall be automatically reduced,
so that no vacancy shall be created thereby.  A two-thirds majority of
directors then in office may, in the case of a vacancy occurring by reason of
an increase in the number of directors, fill such vacancy for a term of office
continuing only until the next election of one or more directors by the
shareholders; provided, however, that the Board of Directors may not fill more
than two directorships to be filled by reason of an increase in the number of
directors between any two successive annual meetings of shareholders.

                 Section 5.  The Board of Directors, by resolution adopted by a
majority of the full Board of Directors, may designate from among its members
one or more committees, each of which, to the extent provided in such
resolution, or in the





                                       12
<PAGE>   13
Articles of Incorporation or in the Bylaws of the corporation, shall have and
may exercise all of the authority of the Board of Directors, except that no
such committee shall have the authority of the Board of Directors in reference
to amending the Articles of Incorporation, approving a plan of merger or
consolidation, recommending to the shareholders the sale, lease, or exchange of
all or substantially all of the property and assets of the corporation
otherwise than in the usual and regular course of its business, recommending to
the shareholders a voluntary dissolution of the corporation or a revocation
thereof, amending, altering, or repealing the Bylaws of the corporation or
adopting new Bylaws for the corporation, filling vacancies in the Board of
Directors or any such committee, electing or removing officers or members of
any such committee, fixing the compensation of any member of such committee, or
altering or repealing any resolution of the Board of Directors which by its
terms provides that it shall not be so amendable or repealable; and, unless
such resolution, the Articles of Incorporation, or the Bylaws of the
corporation expressly so provide, no such committee shall have the power or
authority to declare a distribution or share dividend or to authorize the
issuance of shares of the corporation.

                       MEETINGS OF THE BOARD OF DIRECTORS

                 Section 6.  The Directors of the corporation may hold their
meetings, both regular and special, either within or without the State of
Texas.

<PAGE>   14
                 Section 7.  An organizational meeting of the Board of
Directors shall be held without further notice immediately following the annual
meeting of shareholders, and at the same place, unless, by unanimous consent of
the Directors then elected and serving such time or place shall be changed.

                 Section 8. Regular meetings of the Board of Directors may be
held with or without notice at such time and place as shall from time to time
be determined by the Board of Directors.

                 Section 9. Special meetings of the Board of Directors may be
called on twenty-four (24) hours' notice to each Director, or such shorter
period of time as the person calling the meeting deems appropriate in the
circumstances, either personally, or by mail, or by telegram; special meetings
shall be called by the Chairman or the President or, in the event of the
inability of both the Chairman and the President to act, the Corporate
Secretary in like manner and on like notice on the written request of two
Directors.  Neither the business to be transacted at, nor the purpose of, any
special meeting need be specified in a notice or waiver of notice.

                 Section 10.  At all meetings of the Board of Directors the
presence of a majority of the Directors shall constitute a quorum for the
transaction of business and the act of a majority of the Directors present at
any meeting at which there is a quorum shall be the act of the Board of
Directors.  Any action required or permitted to be taken at a meeting of the
Board of Directors may be taken without a meeting if a consent in writing,





                                       14
<PAGE>   15
setting forth the action so taken, is signed by all members of the Board of
Directors.  If a quorum shall not be present at any meeting of Directors, the
Directors present thereat may adjourn the meeting from time to time, without
notice other than announcement at the meeting, until a quorum shall be present.

                 Section 11.  COMPENSATION OF DIRECTORS.  The Board of
Directors shall have authority to establish, from time to time, the amount of
compensation which shall be paid to its members for their services as
Directors.

                 Section 12.  Upon compliance with the notice requirements of
this Article or waiver of notice, a meeting of the Board of Directors may be
conducted by means of conference telephone or similar communications equipment
if all persons participating in the meeting can hear each other.

                                   ARTICLE IV

                                    NOTICES

                 Section 1.  Whenever under the provisions of the statutes or
of the Articles of Incorporation or of these Bylaws, notice is required to be
given to any Director or shareholder, and no provision is made as to how such
notice shall be given, it shall not be construed to mean personal notice, but
any such notice may be given in writing, postage prepaid, addressed to such
Director or shareholder at such address as appears on the books of the
corporation.  Any notice required or permitted to be given by mail shall be
deemed to be given at the time when the same shall be thus deposited in the
United States mails as aforesaid.

                 Section 2.  Whenever any notice is required to be given to any
shareholder or Director of the corporation under the provisions of the statutes
or of the Articles of Incorporation, or of these Bylaws, a waiver thereof in
writing signed by the person or persons entitled to such notice, whether before
or after the time stated in such notice, shall be equivalent to the giving of
such notice.  Attendance of a Director at a meeting shall constitute a waiver
of notice of such meeting, except when a Director attends a meeting for the
express purpose, in writing filed at the meeting, of objecting to the
transaction of any business on the grounds that the meeting is not lawfully
called or held.

                                   ARTICLE V

                                    OFFICERS

a Chairman, a President, one or more Executive Vice Presidents, Senior Vice
Presidents or Vice Presidents, a General Counsel, a Controller, a Corporate
Secretary and a Treasurer, all of whom shall be elected by the Board of
Directors.  Any two or more offices may be held by the same person, except that
the Chairman or the President and the Corporate Secretary shall not be the same
person.  Each such executive officer shall have such authority and perform such
duties in the management of the corporation as may be determined by resolution
of the Board of Directors.

<PAGE>   17
                 Section 2.  The Board of Directors may elect or appoint such
other officers and agents as it shall deem necessary, who shall hold their
offices for such term and who shall have such authority and perform such duties
as may be prescribed by the Board of Directors or the President.  The power to

applicable law of the United States or the State of California, or of any
order, rule, regulation, decree or judgment of any governmental body, power or
court having jurisdiction over this corporation, or over the subject matter to
which such provision of these Bylaws applies or may apply, such provision of
these Bylaws shall be inoperative to the extent only that the operation thereof

judgment, and shall in all other respects be in full force and effect.

                                   ARTICLE I

                            MEETINGS OF SHAREHOLDERS

         Section 1.       PLACE OF MEETINGS.  Meetings of shareholders shall be

         Section 2.       ANNUAL MEETINGS.  The annual meeting of shareholders
shall be held each year on such date and at such time as may be designated by

         Section 3.       SPECIAL MEETINGS.  A special meeting of the
shareholders, for any purpose or purposes whatsoever, may be called at any time
by the Board of Directors, or by the Chairman, or by the President, or by one

the receipt of the request.  If the notice is not given within twenty (20) days
after receipt of the request, the person or persons requesting the meeting may

shareholders called by action of the Board of Directors the Chairman or the
President may be held.

         Section 4.       NOTICE OF SHAREHOLDERS' MEETINGS.  All notices of
meetings of shareholders shall be sent or otherwise given in accordance with
Section 5 of this Article II not less than ten (10) nor more than sixty (60)

place, date and hour of the meeting and (i) in the case of a special meeting,
the general nature of the business to be transacted, or (ii) in the case of the
annual meeting, those matters which the Board of Directors, at the time of
giving the notice, intends to present for action by the shareholders.  The
notice of any





                                       3
<PAGE>   4
meeting at which directors are to be elected shall include the name of any
nominee or nominees which, at the time of the notice, management intends to
present for election.

         Section 5.       MANNER OF GIVING NOTICE: AFFIDAVIT OF NOTICE.  Notice
of any meeting of shareholders shall be given either personally or by
first-class mail or other means of written communication, addressed to the
shareholder at the address of such shareholder appearing on the books of the
corporation or given by the shareholder to the corporation for the purpose of
notice.  If no such address appears on the corporation's books or is given,
notice shall be deemed to have been given if sent to the corporation's
principal executive office, or if published at least once in a newspaper of
general circulation in the county in which such office is located.  Notice
shall be deemed to have been given at the time when delivered personally or
deposited in the mail or sent by other means of written communication.

                 If any notice addressed to a shareholder at the address of
such shareholder appearing on the books of the corporation is returned to the
corporation by the United States Postal Service marked to indicate that the
United States Postal Service is unable to deliver the notice to the shareholder
at such address, all future notices or reports shall be deemed to have been
duly given without further mailing if the same shall be available to the
shareholder upon written demand of the shareholder at the principal executive
office of the corporation for a period of one year from the date of the giving
of such notice.





                                       4
<PAGE>   5
                 An affidavit of the mailing or other means of giving any
notice of any shareholders' meeting shall be executed by the Corporate
Secretary, Assistant Corporate Secretary or any transfer agent of the
corporation giving such notice, and shall be filed and maintained in the minute
book of the corporation

         Section 6.       QUORUM.  The presence in person or by proxy of the
holders of a majority of the shares entitled to vote at any meeting of
shareholders shall constitute a quorum for the transaction of business.  The
shareholders present at a duly called or held meeting at which a quorum is
present may continue to do business until adjournment, notwithstanding the
withdrawal of enough shareholders to leave less than a quorum, if any action
taken (other than adjournment) is approved by at least a majority of the shares
required to constitute a quorum.

         Section 7.       ADJOURNED MEETING AND NOTICE THEREOF.  Any
shareholders' meeting, annual or special, whether or not a quorum is present,
may be adjourned from time to time by the vote of the majority of the shares
represented at such meeting, either in person or by proxy, but in the absence
of a quorum, no other business may be transacted at such meeting.

                 When any meeting of shareholders, either annual or special, is
adjourned to another time or place, notice need not be given of the adjourned
meeting if the time and place thereof are announced at a meeting at which the
adjournment is taken, unless a new record date for the adjourned meeting is
fixed, or unless the adjournment is for more than forty-five (45) days from





                                       5
<PAGE>   6
the date set for the original meeting, in which case the Board of Directors
shall set a new record date.  Notice of any such adjourned meeting shall be
given to each shareholder of record entitled to vote at the adjourned meeting
in accordance with the provisions of Sections 4 and 5 of this Article II.  At
any adjourned meeting the corporation may transact any business which might
have been transacted at the original meeting.

         Section 8.       VOTING.  Unless a record date for voting purposes is
fixed as provided in Section 1 of Article VIII of these Bylaws, then, subject
to the provisions of Section 702 to Section 704, inclusive, of the California
Corporations Code (the "Code"), only persons in whose names shares entitled to
vote stand on the stock records of the corporation at the close of business on
the business day next preceding the day on which notice is given (or, if notice
is waived, at the close of business on the business day next preceding the day
on which the meeting is held) shall be entitled to vote at such meeting.  Any
shareholder entitled to vote on any matter other than elections of directors or
officers, may vote part of the shares held by such person in favor of the
proposal and refrain from voting the remaining shares held by such person or
vote them against the proposal, but, if the shareholder fails to specify the
number of shares such shareholder is voting affirmatively, it will be
conclusively presumed that the shareholder's approving vote is with respect to
all shares such shareholder is entitled to vote.  Such vote may be by voice
vote or by ballot; provided, however,





                                       6
<PAGE>   7
that all elections for directors must be by ballot upon demand by a shareholder
at any election and before the voting begins.

                 At a shareholders' meeting involving the election of
directors, no shareholder shall be entitled to cumulate votes (i.e., cast for
any one or more candidates a number of votes greater than the number of the
shareholder's shares) unless the names of such candidate(s) have been placed in
nomination prior to the voting and a shareholder has given notice prior to the
voting of the shareholder's intention to cumulate votes.  If any shareholder
has given such notice, then each shareholder entitled to vote may cumulate such
shareholder's votes for candidates in nomination and give one candidate a
number of votes equal to the number of directors to be elected multiplied by
the number of votes to which such shareholder's shares are entitled, or
distribute the shareholder's vote on the same principle among any or all of the
candidates, as the shareholder thinks fit.  The candidates receiving the
highest number of votes up to the number of directors to be elected shall be
elected.

         Section 9.       WAIVER OF NOTICE OR CONSENT BY ABSENT SHAREHOLDERS.
The transactions at any meeting of shareholders, either annual or special,
however called and noticed, and wherever held, shall be as valid as though had
at a meeting duly held after regular call and notice, if a quorum be present
either in person or by proxy, and if, either before or after the meeting, each
person entitled to vote, not present in person or





                                       7
<PAGE>   8
by proxy, signs a written waiver of notice or a consent to a holding of the
meeting, or an approval of the minutes thereof.

                 Attendance of a person at a meeting shall also constitute a
waiver of notice of such meeting, except when the person objects, at the
beginning of the meeting, to the transaction of any business because the
meeting is not lawfully called or convened, and except that attendance at a
meeting is not a waiver of any right to object to the consideration of matters
not included in the notice if such objection is expressly made at the meeting.

         Section 10.      SHAREHOLDER ACTION BY WRITTEN CONSENT WITHOUT A
MEETING.  Any action which may be taken at any annual or special meeting of
shareholders may be taken without a meeting and without prior notice, if a
consent in writing, setting forth the action so taken, is signed by the holders
of outstanding shares having not less than the minimum number of votes that
would be necessary to authorize or take such action at a meeting at which all
shares entitled to vote thereon were present and voted.  In the case of
election of directors, such consents shall be effective only if signed by the
holders of all outstanding shares entitled to vote for the election of
directors.  All such consents shall be filed with the Corporate Secretary and
shall be maintained in the corporate records.  Any shareholder giving a written
consent, or the shareholder's proxy holders, or a transferee of the shares or a
personal representative of the shareholder or their respective proxy holders,
may revoke the





                                       8
<PAGE>   9
consent by a writing received by the Corporate Secretary prior to the time that
written consents of the number of shares required to authorize the proposed
action have been filed with the Corporate Secretary.

                 If the consents of all shareholders entitled to vote have not
been solicited in writing, and if the unanimous written consent of all such
shareholders shall not have been received, the Corporate Secretary shall give
prompt notice of the corporate action approved by the shareholders without a
meeting.

         Section 11.      PROXIES.  Every person entitled to vote for directors
or on any other matter shall have the right to do so either in person or by one
or more agents authorized by a written proxy signed by the person and filed
with the Corporate Secretary.  A proxy shall be deemed signed if the
shareholder's name is placed on the proxy (whether by manual signature,
typewriting, telegraphic transmission or otherwise) by the shareholder or the
shareholder's attorney in fact.  A validly executed proxy which does not state
that it is irrevocable shall continue in full force and effect unless revoked
by the person executing it, prior to the vote pursuant thereto, by a writing
delivered to the corporation stating that the proxy is revoked or by a
subsequent proxy executed by, or attendance at the meeting and voting in person
by the person executing the proxy; provided, however, that no such proxy shall
be valid after the expiration of eleven (11) months from the date of such
proxy, unless otherwise provided in the proxy.

                                   DIRECTORS

         Section 1.       POWERS.  Subject to the provisions of the Code and
any limitations in the Articles of Incorporation and these Bylaws relating to
action required to be approved by the shareholders or by the outstanding
shares, the business and affairs of the corporation shall be managed and all
corporate powers shall be exercised by or under the direction of the Board of
Directors.

                 Without prejudice to such general powers, but subject to the
same limitations, it is hereby expressly declared that the directors shall have
the power and authority to:

                 (a)      Select and remove all officers, agents and employees
         of the corporation, prescribe such powers and duties for them as may
         not be inconsistent with law, with the Articles of Incorporation or
         these Bylaws, fix their compensation and require from them security
         for faithful service.

                 (b)      Change the principal executive office or the
         principal business office from one location to another; cause the
         corporation to be qualified to do business in any other state,
         territory, dependency or foreign country; cause the corporation to
         conduct business within or without the State of California; designate
         any place within or without the State of California for the holding of
         any shareholders' meeting or meetings, including annual meetings;
         adopt, make





                                       10
<PAGE>   11
         and use a corporate seal, and prescribe the forms of certificate of
         stock, and alter the form of such seal and of such certificates from
         time to time as in their judgment they may deem best, provided that
         such forms shall at all times comply with the provisions of law.

                 (c)      Authorize the issuance of shares of stock of the
         corporation from time to time, upon such terms as may be lawful, in
         consideration of money paid, labor done or services actually rendered,
         debts or securities canceled, tangible or intangible property actually
         received.

                 (d)      Borrow money and incur indebtedness for the purpose
         of the corporation, and cause to be executed and delivered therefor,
         in the corporate name, promissory notes, bonds, debentures, deeds of
         trust, mortgages, pledges, hypothecations, or other evidences of debt
         and securities therefor.

         Section 2.       NUMBER AND QUALIFICATION OF DIRECTORS.  The Board of
Directors shall consist of three directors.  Directors need not be shareholders
or residents of the State of California.

         Section 3. ELECTION AND TERM OF OFFICE OF DIRECTORS.  Directors shall
be elected at each annual meeting of the shareholders to hold office until the
next annual meeting, but if any such annual meeting is not held or the
directors are not elected at any annual meeting, the directors may be elected
at any special meeting of shareholders held for that purpose, or at the next
annual meeting of shareholders held thereafter.  Each





                                       11
<PAGE>   12
director, including a director elected to fill a vacancy, shall hold office
until the expiration of the term for which elected and until a successor has
been elected and qualified or until his earlier resignation or removal or his
office has been declared vacant in the manner provided in these Bylaws.

         Section 4.       RESIGNATION AND REMOVAL OF DIRECTORS.  Any director
may resign effective upon giving written notice to the Chairman, the President,
the Corporate Secretary or the Board of Directors, unless the notice specifies
a later time for the effectiveness of such resignation, in which case such
resignation shall be effective at the time specified.  Unless such resignation
specifies otherwise, its acceptance by the corporation shall not be necessary
to make it effective.  The Board of Directors may declare vacant the office of
a director who has been declared of unsound mind by an order of court or
convicted of a felony.  Any or all of the directors may be removed either for
or without cause if such removal is approved by the affirmative vote of a
majority of the outstanding shares entitled to vote, provided that no director
may be removed without cause (unless the entire Board is removed) when the
votes cast against removal (or, if such action is taken by written consent, the
shares held by persons not consenting in writing to such removal) would be
sufficient to elect such director if voted cumulatively at an election at which
the same total number of votes were cast (or, if such action is taken by
written consent, all shares entitled to vote were voted) and the entire number
of





                                       12
<PAGE>   13
directors authorized at the time of the director's most recent election were
then being elected.  No reduction of the authorized number of directors shall
have the effect of removing any director before his term of office expires.

         Section 5.       VACANCIES.  Vacancies in the Board of Directors may
be filled by a majority of the remaining directors, though less than a quorum,
or by a sole remaining director, except that a vacancy created by the removal
of a director by the vote or written consent of the shareholders or by court
order may be filled only by approval of the shareholders.

         A vacancy in the Board of Directors exists as to any authorized
position of director which is not then filled by a duly elected director,
whether caused by death, resignation, removal, increase in the authorized
number of directors or otherwise.

         The shareholders may elect a director or directors at any time to fill
any vacancy or vacancies not filled by the directors, but any such election by
written consent shall require the consent of a majority of the outstanding
shares entitled to vote.  If the resignation of a director is effective at a
future time, the Board of Directors may elect a successor to take office when
the resignation becomes effective.

         Section 6.       PLACE OF MEETINGS.  Regular meetings of the Board of
Directors may be held at any place within or without the State of California as
shall from time to time be determined by the Board of Directors.  In the
absence of such designation,





                                       13
<PAGE>   14
regular meetings shall be held at the principal executive office of the
corporation.  Special meetings of the Board shall be held at any place within
or without the State of California that has been designated in the notice of
the meeting or, if not stated in the notice or if there is not notice, at the
principal executive office of the corporation.  Any meeting, regular or
special, may be held by conference telephone or similar communication
equipment, so long as all directors participating in such meeting can hear one
another, and all such directors shall be deemed to be present in person at such
meeting.

         Section 7.       ANNUAL MEETINGS.  Immediately following each annual
meeting of shareholders, the Board of Directors shall hold a regular meeting
for the purpose of transaction of other business.  Notice of this meeting shall
not be required.

         Section 8.       OTHER REGULAR MEETINGS.  Other regular meetings of
the Board of Directors shall be held at such time as shall from time to time be
fixed by the Board of Directors.  Such regular meetings may be held with or
without notice, provided that notice of any change in the time of any such
meetings shall be given to all of the directors.  Notice of a change in the
determination of the time shall be given to each director in the same manner as
notice for special meetings of the Board of Directors.

         Section 9.       SPECIAL MEETINGS.  Special meetings of the Board of
Directors for any purpose or purposes may be called at any time by the Chairman
or the President or any director.

<PAGE>   15
                 Notice of the time and place of special meetings shall be
delivered personally or by telephone to each director or sent by first-class
mail or telegram, charges prepaid, addressed to each director at his or her
address as it is shown upon the records of the corporation.  In case such
notice is mailed, it shall be deposited in the United States mail at least four
(4) days prior to the time of the holding of the meeting.  In case such notice
is delivered personally, or by telephone or telegram, it shall be delivered
personally or by telephone or to the telegraph company at least forty-eight
(48) hours prior to the time of the holding of the meeting.  Any oral notice
given personally or by telephone may be communicated to either the director or
to a person at the office of the director who the person giving the notice has
reason to believe will promptly communicate it to the director.  The notice
need not specify the purpose of the meeting nor the place if the meeting is to
be held at the principal executive office of the corporation.

         Section 10.      QUORUM.  A majority of the authorized number of
directors shall constitute a quorum for the transaction of business, except to
adjourn as hereinafter provided.  Every act or decision done or made by a
majority of the directors present at a meeting duly held at which a quorum is
present shall be regarded as the act of the Board of Directors.  A meeting at
which a quorum is initially present may continue to transact business
notwithstanding the withdrawal of directors, if any





                                       15
<PAGE>   16
action taken is approved by at least a majority of the required quorum for such
meeting.

         Section 11.      WAIVER OF NOTICE.  The transactions of any meeting of
the Board of Directors, however called and noticed or wherever held, shall be
as valid as though had at a meeting duly held after regular call and notice if
a quorum be present and if, either before or after the meeting, each of the
directors not present signs a written waiver of notice, a consent to holding
the meeting or an approval of the minutes thereof.  The waiver of notice or
consent need not specify the purpose of the meeting.  All such waivers, consents
and approvals shall be filed with the corporate records or made a part of the
minutes of the meeting.  Notice of a meeting shall also be deemed given to any
director who attends the meeting without protesting, prior thereto or at its
commencement, the lack of notice to such director.

         Section 12.      ADJOURNMENT.  A majority of the directors present,
whether or not constituting a quorum, may adjourn any meeting to another time
and place.

         Section 13.      NOTICE OF ADJOURNMENT.  Notice of the time and place
of holding an adjourned meeting need not be given, unless the meeting is
adjourned for more than twenty-four (24) hours, in which case notice of such
time and place shall be given prior to the time of the adjourned meeting, in
the manner specified in Section 8 of this Article III, to the directors who
were not present at the time of the adjournment.





                                       16
<PAGE>   17
         Section 14.      ACTION WITHOUT MEETING.  Any action required or
permitted to be taken by the Board of Directors may be taken without a meeting,
if all members of the Board shall individually or collectively consent in
writing to such action.  Such action by written consent shall have the same
form and effect as a unanimous vote of the Board of Directors.  Such written
consent or consents shall be filed with the minutes of the proceedings of the
Board.

         Section 15. FEES AND COMPENSATION OF DIRECTORS.  Directors and members
of committees may receive such compensation, if any, for their services, and
such reimbursement of expenses, as may be fixed or determined by resolution of
the Board of Directors.  Nothing herein contained shall be construed to
preclude any director from serving the corporation in any other capacity as an
officer, agent, employee or otherwise, and receiving compensation for such
services.

designate one or more committees, each consisting of two or more directors, to
serve at the pleasure of the Board.  The Board may designate one or more
directors as alternate members of any committee, who may replace any absent
member at any meeting of the committee.  Any such committee, to the extent

holding such office or position, to the extent that such additional rights to
indemnification are authorized in the Articles of Incorporation.

director, officer, employee or agent of the corporation

<PAGE>   27

capacity or arising out of such person's status as such, whether or not the
corporation would have the power to indemnify him against such liability under

mandated by law or the order, judgment or decree of any court of competent
jurisdiction, in any circumstance where it appears:

                 (a)      That it would be inconsistent with a provision of the
         Articles of Incorporation, these Bylaws, a resolution of the
         shareholders or an agreement in effect at the time of the accrual of
         the alleged cause of the action asserted in the proceeding in which
         the expense were incurred or other amounts were paid, which prohibits
         or otherwise limits indemnification; or

                 (b)      That it would be inconsistent with any condition
         expressly imposed by a court in approving a settlement.

         Section 7.       AMENDMENT.  The provisions of this Article relating
to indemnification shall constitute a contract between the corporation and each
of its directors and officers entitled to such indemnification hereunder which
may be modified as to any director or officer only with that person's consent
or as specifically provided in this Section.  Notwithstanding any other
provision of these Bylaws relating to their amendment generally,





                                       27
<PAGE>   28
any repeal or amendment of this Article which is adverse to any director or
officer shall apply to such director or officer only on a prospective basis and
shall not limit the rights of an indemnitee to indemnification with respect to
any action or failure to act occurring prior to the time of such repeal or
amendment.  Notwithstanding any other provision of these Bylaws, no repeal or
amendment of these Bylaws shall affect any or all of this Article so as to
limit or reduce the indemnification in any manner unless adopted by (a) the
unanimous vote of the directors of the corporation then serving, or (b) by the
shareholders; provided that no such amendment shall have retroactive effect
inconsistent with the preceding sentence.

         Section 8.       CHANGES IN CALIFORNIA LAW.  References in this
Article to the Code or to any provision thereof shall be to such law as it
existed on the date this Article was adopted or as such law thereafter may be
changed; provided that (a) in the case of any change which expands the
liability of directors or officers or limits the indemnification rights or the
rights to advancement of expenses which the corporation may provide, the rights
to limited liability, to indemnification and to the advancement of expenses
provided in the corporation's Articles of Incorporation and/or these Bylaws
shall continue as theretofore to the extent permitted by law; and (b) if such
change permits the corporation, without the requirement of any further action
by shareholders or directors, to limit further the liability of directors (or
limit the liability of officers) or to provide





                                       28
<PAGE>   29
broader indemnification rights or rights to the advancement of expenses than
the corporation was permitted to provide prior to such change, then liability
thereupon shall be so limited and the rights to indemnification and the
advancement of expenses shall be so broadened to the extent permitted by law.

                                  ARTICLE VII

                              RECORDS AND REPORTS

         Section 1. MAINTENANCE AND INSPECTION OF SHARE REGISTER.  The

its transfer agent or registrar, if either be appointed and as determined by
resolution of the Board of Directors, a record of its shareholders, giving the
names and addresses of all shareholders and the number and class of shares held
by each shareholder.

         A shareholder or shareholders of the corporation holding at least five
percent (5%) in the aggregate of the outstanding voting shares of the
corporation may (i) inspect and copy the records of shareholders' names and
addresses and shareholdings during usual business hours upon five days prior
written demand upon the corporation, and/or (ii) obtain from the transfer agent
of the corporation, upon written demand and upon the tender of such transfer
agent's usual charges for such list, a list of the shareholders' names and
addresses, who are entitled to vote for the election of directors, and their
shareholdings, as of the most recent record date for which such list has been
compiled or as of a date specified by the shareholder subsequent to the date





                                       29
<PAGE>   30
of demand.  Such list shall be made available by the transfer agent on or
before the later of (i) five (5) days after the demand is received, or (ii) the
date specified in the request as the date as of which the list is to be

         Section 2. MAINTENANCE OF BYLAWS.  The corporation shall keep at its
principal executive office, or, if its principal executive office is not in the
State of California, at its principal business office in the State of
California, the original or a copy of these Bylaws as amended to date.

         Section 3.       ANNUAL REPORT TO SHAREHOLDERS.  The annual report to
shareholders referred to in Section 1501 of the Code is expressly dispensed
with, but nothing herein shall be interpreted as prohibiting the Board of
Directors from issuing annual or other periodic reports to the shareholders of
the corporation as they deem appropriate.

the corporation shall be signed by the Controller or Assistant Controller, or
such agents and employees as the

<PAGE>   31
President may from time to time designate and authorize to sign for the
Controller, and countersigned by the Treasurer or any Assistant Treasurer, or
such agents and employees as the President may from time to time designate and
authorize to sign for the Treasurer; and when so designated by the President,
the signature of the Treasurer or an Assistant Treasurer may be affixed by the

funds from any bank or depository at which the corporation has funds on deposit
to any other bank or depository of the corporation for credit to the
corporation's account, a form of check having plainly printed upon its face
"DEPOSITORY TRANSFER CHECK" and being by its wording payable to a bank or
depository for credit to the account of the corporation, is hereby authorized,
and such checks shall require no signature other than the name of the
corporation printed at the lower right corner; and further provided that
checks, drafts and bills of exchange issued in the name of the corporation in
the amount of $5,000, or the equivalent thereof in foreign currency, or less

check-signing machine, or the manual signature of such agents and employees as
the President may from time to time designate and authorize to sign for the
Treasurer; and further provided that no person authorized to sign checks or

applicable manner, but not otherwise, every check, draft or bill





                                       31
<PAGE>   32
of exchange issued in the name of the corporation and calling for the payment
of money out of the General Bank Accounts, Depository Bank Accounts, and
Special Bank Accounts of the corporation shall be valid and enforceable
according to its wording, tenor and effect, but not otherwise.  Provided
however, that for the purpose of transferring funds between accounts of the
corporation, from accounts of the corporation to accounts of Pool Energy
Services Co. and its subsidiaries and affiliates, from accounts of the
corporation to accounts of subsidiaries and affiliates, and from accounts of
the corporation for the purpose of investment of corporate funds, the Treasurer

<PAGE>   33
may be needed in carrying on and dispatching the business of the corporation,
provided that the Treasurer in establishing and maintaining such accounts shall
keep only such funds therein and in such amount as may be required for the
local needs of such accounts and provided that checks or drafts issued against
or drawn on such accounts shall be valid and binding on the corporation
according to their wording, tenor and effect when signed by either the
Treasurer of the corporation or by such agent or employee of the corporation as
may be designated by the Treasurer in writing to such bank or when signed in
such manner and by such agent or employee of the corporation as may be
designated by the President of the corporation; and further provided that
checks and drafts issued in the name of the corporation against funds in such
Agent's Account or Local Manager's Account in the amount of $1,000.00 or more

                           GENERAL CORPORATE MATTERS

         Section 1.       RECORD DATE.  For purposes of determining the
shareholders entitled to notice of any meeting or to vote or entitled to
receive payment of any dividend or other distribution or allotment of any
rights or entitled to exercise any rights in respect of any other lawful
action, the Board of Directors may fix, in advance, a record date, which shall
not be more than sixty (60) days not less than ten (10) days prior to the date
of





                                       33
<PAGE>   34
any such meeting nor more than sixty (60) days prior to any other action, and
in such case only shareholders of record on the date so fixed are entitled to
notice and to vote or to receive the dividend, distribution or allotment of
rights or to exercise the rights, as the case may be, notwithstanding any
transfer of any shares on the books of the corporation after the record date
fixed as aforesaid, except as otherwise provided in the Code.

         If the Board of Directors does not so fix a record date:

                 (a)      The record date for determining shareholders entitled
         to notice of or to vote at a meeting of shareholders shall be at the
         close of business on the business day next preceding the day on which
         notice is given or, if notice is waived, at the close of business on
         the business day next preceding the day on which the meeting is held.

                 (b)      The record date for determining shareholders entitled
         to give consent to corporate action in writing without a meeting, when
         no prior action by the Board has been taken, shall be the day on which
         the first written consent is given.

                 (c)      The record date for determining shareholders for any
         other purpose shall be at the close of business on the day on which
         the Board adopts the resolution relating thereto, or the sixtieth
         (60th) day prior to the date of such other action, whichever is later.





                                       34
<PAGE>   35
         Section 2.   NOTES AND OTHER EVIDENCES OF INDEBTEDNESS.  All notes or
other evidences of indebtedness issued in the name of or payable by the
corporation shall be signed by the President or any Vice President and by the
Treasurer or any Assistant Treasurer, or by such other person or persons and in
such manner as, from time to time, shall be determined by resolution of the
Board of Directors.

         Section 3.   CORPORATE CONTRACTS AND INSTRUMENTS: HOW EXECUTED.  The
Board of Directors, except as in the Bylaws otherwise provided, may authorize
any officer or officers, agent or agents, to enter into any contract or execute
any instrument in the name of and on behalf of the corporation, and such
authority may be general or confined to specific instances; and, unless so
authorized or ratified by the Board of Directors or within the agency power of
an officer, no officer, agent or employee shall have any power or authority to
bind the corporation by any contract or engagement or to pledge its credit or to
render it liable for any purpose or to any amount.

         Section 4.   STOCK CERTIFICATES.  A certificate or certificates for
shares of the capital stock of the corporation shall be issued to each
shareholder when any such shares are fully paid, and the Board of Directors may
authorize the issuance of certificates or shares as partly paid provided that
such certificates shall state the amount of the consideration to be paid
therefor and the amount paid thereon.





                                       35
<PAGE>   36
All certificates shall be signed in the name of the corporation (i) by the
Chairman, the President or a Vice President, and (ii) by the chief financial
officer or Treasurer or any Assistant Treasurer or the Corporate Secretary or
any Assistant Corporate Secretary, certifying the number of shares and the
class or series of shares owned by the shareholder.  Any or all of the
signatures on the certificate may be facsimile.  In case any officer, transfer
agent, or registrar who has signed or whose facsimile signature has been placed
upon a certificate shall have ceased to be such officer, transfer agent or
registrar before such certificate is issued, it may be issued by the
corporation with the same effect as if such person were an officer, transfer
agent or registrar at the date of issue.

                 Any such certificate shall also contain such legend or other
statement as may be required by Section 418 of the Code, the Corporate
Securities Law of 1968, any other state or federal securities law or any
agreement between the corporation and the issue thereof, and may contain such
legend or other statement as may be required by any other applicable law or
regulation or agreement.

                 No new certificate for shares shall be issued in place of any
certificate theretofore issued unless the latter is surrendered and canceled at
the same time; provided, however, that a new certificate may be issued without
the surrender and cancellation of the old certificate if the certificate
theretofore issued is alleged to have been lost, stolen or





                                       36
<PAGE>   37
destroyed.  In case of any such allegedly lost, stolen or destroyed
certificate, the corporation may require the owner thereof or the legal
representative of such owner to give the corporation a bond (or other adequate
security) sufficient to indemnify it against any claim that may be made
against it (including any expense or liability) on account of the alleged loss,
theft or destruction of any such certificate or the issuance of such new
certificate.

         Section 5.       LOST CERTIFICATES.  Except as hereinafter in this
Section provided, no new certificates for shares shall be issued in lieu of an
old certificate unless the latter is surrendered to the corporation and
canceled at the same time.  The Board of Directors may in case any share
certificate or certificate for any other security is lost, stolen, or
destroyed, authorize the issuance of a new certificate in lieu thereof, upon
such terms and conditions as the Board may require including provision for
indemnification of the corporation against any claim that may be made against
it, including any expense or liability, on account of the alleged loss, theft,
or destruction of such certificate or the issuance of such new certificate.

         Section 6.       REPRESENTATION OF SHARES OF OTHER CORPORATIONS.  The
Chairman, the President, any Vice President, or any other person authorized by
resolution of the Board of Directors is authorized to vote on behalf of the
corporation any and all shares of any other corporation or corporations,
foreign or domestic, standing in the name of the corporation.  The





                                       37
<PAGE>   38
authority herein granted to said officers or other persons to vote or represent
on behalf of the corporation any and all shares held by the corporation in any
other corporation or corporations may be exercised either in person or by duty
executed proxy.

         Section 7.       CONSTRUCTION AND DEFINITIONS.  Unless the context
requires otherwise, the general provisions, rules of construction, and
definitions in the Code shall govern the construction of these Bylaws.  Without
limiting the generality of the foregoing, the singular number includes the
plural, the plural number includes the singular, and the term "person"

includes both a corporation and a natural person.

                                   ARTICLE X

                                   AMENDMENTS

         Section 1.       AMENDMENT BY SHAREHOLDERS.  New bylaws may be adopted
or these Bylaws may be amended or repealed by the affirmative vote of a
majority of the outstanding shares entitled to vote, or by the written consent
of shareholders entitled to vote such shares, except as otherwise provided by
law or by the Articles of Incorporation.  If, at any meeting of shareholders,
action is proposed to be taken to amend, repeal or adopt Bylaws, the notice of
such meeting shall include a brief statement or summary of the proposed action.

party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative
or investigative (other than an action by or in the right of the corporation)
by reason of the fact he is or was a director, officer, or employee or agent of
the corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, against expenses (including

<PAGE>   25

Drilling Company, Inc. hereinafter collectively referred to as the "Parties."

                                   WITNESSETH:

The Parties desire to establish a joint venture for the purpose of entering into

      of Alaska ("Contracts"). The Joint Venture shall conduct no other
      business, and KUUKPIK and PAA are not, and shall not be deemed to be,

      shall operate on the North Slope only pursuant to Subcontracts with the
      Joint Venture substantially in the form of Exhibit "A" attached hereto
      (the "Subcontractors") under which PAA shall undertake to perform all
      services required of the Joint Venture under the Contracts. KUUKPIK shall
      not participate in the providing of drilling and/or workover rig services

      of this Agreement with, through or by means of any entity or vehicle other
      than the Joint Venture.

2.    Rig Use: Nothing in this agreement prohibits or limits PAA's right to
      employ any drilling or workover rig to work outside the North Slope of
      Alaska, independent of the Joint Venture.

3.    Name and Location of Joint Venture: The name of the Joint Venture shall be
      KUUKPIK/Pool Arctic Alaska and its principal place of business shall be at
      5801 Silverado Way, Anchorage, Alaska, 99518.

                                                      ---
                     Total                            100%
                    
      Distribution of profits will occur within 15 days following receipt of
      funds in payment for services provided under Contracts. KUUKPIK shall have
      no liability for any losses incurred by the Joint Venture.

6.    Capital Contributions: The Parties shall contribute cash in an aggregate 
      amount of $4,000 as capital to the Joint Venture, of which KUUKPIK shall
      contribute $2,040 and PAA shall contribute $1,960. The Joint Venture will
      not acquire any rigs, equipment or other property but will operate only
      through the Subcontracts.

7.    Performance of Services:  The Joint Venture shall subcontract exclusively 
      with PAA to provide the rigs, equipment, expertise, personnel and capital
      to perform the services called for in the Contracts. PAA will be

      PAA shall indemnify and defend the Joint Venture against any and all
      claims or losses arising out of or in connection with PAA's management of
      the Joint Venture and performance of the services pursuant to
      Subcontracts, including but not limited to claims, losses or costs arising
      from non-compliance with permits, statutes or regulations, negligence, and
      breaches of contracts with third parties; provided however that PAA's
      obligation to indemnify and defend the Joint Venture with respect to

      amounts received pursuant to Contracts and from which accounts shall be
      paid the fees and profit distributions provided for in Paragraphs 5, 7 and
      11 hereof and any other expenses of the Joint Venture.

      (subject to any security interests granted to its creditors) in any and
      all property and equipment used to perform Contracts, and this Agreement
      shall not in any way extend or entitle KUUKPIK or the Joint Venture to any
      ownership right or interest therein.

10.   Grant of Security Interests:  PAA shall have the right to assign its 
      rights under this Agreement and under Subcontracts to its lenders as
      collateral for obligations of PAA. PAA shall further have the right, on
      behalf of the Joint Venture, to assign the Joint Venture's rights under
      Contracts to PAA's lenders, as collateral for separate obligations of PAA,
      provided, however, that such lenders enter into an agreement in form
      satisfactory to KUUKPIK providing for first priority payment by such
      lenders to KUUKPIK, from revenues received pursuant to Contracts, of all

11.   Shareholder Hire/Native Hire Program:  It is agreed that employment of 
      KUUKPIK shareholders and other Native Alaskans is a priority of the Joint
      Venture. KUUKPIK shall be entitled to receive fees as specified below as
      compensation for its efforts in recruiting KUUKPIK shareholders and other
      Native Alaskan personnel for employment by PAA (as Subcontractor to the
      Joint Venture) in connection with Subcontracts. Such fees, however, will
      reduce the amount of profits available for distribution pursuant to
      Paragraph 5 hereof. Fees payable to KUUKPIK shall be as follows:

      a.  A fee of $500 for each KUUKPIK shareholder hired by PAA (as 
          Subcontractor to the Joint Venture) to perform work pursuant to
          Subcontracts.

      b.  A fee of $200 for each non-KUUKPIK shareholder Alaska Native referred 
          by KUUKPIK and hired by PAA (as Subcontractor to the Joint Venture) to
          perform work pursuant to Subcontracts.

      c.  A fee equal to 10% of the gross wages paid to KUUKPIK shareholders as 
          employees of PAA (as Subcontractor to the Joint Venture) in 
          performance of work pursuant to Subcontracts. It is understood by the 
          Parties that all such individuals recruited and referred by KUUKPIK 
          for employment by PAA must be qualified and are subject to all 
          standard employment requirements of PAA. PAA has discretion to not 
          hire or to fire any person referred by KUUKPIK for any reason.

12.   Regular Meetings:  The general manager of PAA and the president of 
      KUUKPIK, or his designee, shall meet monthly to discuss matters
      affecting the Joint Venture. Time and place of the meetings will be
      determined by the Parties. It is understood that monitoring and 
      oversight of the Shareholder Hire/Native Hire Program (Program) and
      obtaining the satisfaction of both KUUKPIK and PAA with its results
      shall be a primary concern of the Parties for discussion at such
      meetings.
      
13.   Monthly Status Report:  PAA will provide KUUKPIK a status report 
      covering activities on contracts of the Joint Venture for each calendar
      month by the 25th day of the succeeding month.  Such status reports 
      will, at a minimum, show the daily status of each rig, Day Rate earned,
      employment fees earned and the profit of the Joint Venture. The actual 
      format of the status report will be determined by mutual agreement of 
      the Parties.
      
14.   Confidentiality; Each party to this Agreement will maintain in
      confidence and will not use or disclose any

         confidential or proprietary information of either Party or of any
         parties to Contracts entered into by the Joint Venture.

15.      Accounting: Right to Audit: KUUKPIK shall be entitled to, at its
         expense, audit PAA books and records as reasonably required to confirm
         the accuracy of the accounting for the Joint Venture. The right to
         audit shall cease twenty-four months following the dissolution of the
         Joint Venture.

                              A NEVADA CORPORATION


         The following constitutes the Bylaws of PCNV, Inc., a corporation duly
incorporated under the laws of the State of Nevada (herein called the
"Corporation").  In the event any provision of these Bylaws is in conflict with
any applicable law of the United States or the State of Nevada, or of any
order, rule, regulation, decree or judgment of any governmental body or power
or court having jurisdiction over the Corporation, or over the subject matter
to which such provision of these Bylaws applies or may apply, such law or
order, rule, regulation, decree or judgment, shall prevail, and the conflicting
provision of these Bylaws shall be inoperative, but in all other respects these
Bylaws shall be and remain in full force and effect.

                                   ARTICLE I
                                  STOCKHOLDERS

Section 1.  Annual Meeting.

         An annual meeting of the stockholders, for the election of directors
to succeed those whose terms expire and for the transaction of such other
business as may properly come before the meeting, shall be held at such place,
on such date, and at such time as the Board of Directors shall each year fix,
which date shall be within thirteen (13) months subsequent to the later of the
date of incorporation or the last annual meeting of stockholders.
<PAGE>   2
Section 2.  Special Meetings.

         Special meetings of the stockholders, for any purpose or purposes
prescribed in the notice of the meeting, may be called by the Board of
Directors of the chief executive officer and shall be held at such place, on
such date, and at such time as they or he or she shall fix.

Section 3.  Notice of Meetings.

         Written notice of the place, date and time of all meetings of the
stockholders shall be given, not less than ten (10) nor more than sixty (60)

entitled to vote at such meeting, except as otherwise provided herein or
required by law (meaning, here and hereinafter, as required from time to time
by the corporation statutes of the State of Nevada, or the Articles of
Incorporation of the Corporation).

         When a meeting is adjourned to another place, date, or time, written
notice need not be given of the adjourned meeting if the place, date, and time
thereof are announced at the meeting at which the adjournment is taken;
provided, however, that if the date of any adjourned meeting is more than
thirty (30) days after the date for which the meeting was originally noticed,
or if a new record date is fixed for the adjourned meeting shall be given in
conformity herewith.  At any adjourned meeting, any business may be transacted

         Notice of any meeting may be waived as provided in Section 2 of
Article V hereof; attendance by a stockholder in person or by proxy at any
meeting shall constitute a waiver of notice thereof by such stockholder.

Section 4.  Quorum.

         At any meeting of the stockholders, the holders of a majority of all
of the shares of the stock entitled to vote at the meeting, present in person
or by proxy, shall constitute a quorum for all purposes, unless or except to
the extent that the presence of a larger number may be required by law.  Where
a separate vote by a class or classes is required, a majority of the shares of
such class or classes present in person or represented by proxy shall
constitute a quorum entitled to take action with respect to that vote on that
matter.

         If a quorum shall fail to attend any meeting, the chairman of the
meeting or the holders of a majority of the shares of stock entitled to vote
who are present, in person or by proxy, may adjourn the meeting to another
place, date, or time.

         If a notice of any adjourned special meeting or stockholders is sent
to all stockholders entitled to vote thereat, stating that it will be held with
those present constituting a quorum, then except as otherwise required by law,
those present at such adjourned meeting shall constitute a quorum, and all
matters shall be determined by a majority of the votes cast at such meeting.

Section 1.  Right to Indemnification.

         Each person who was or is made a party or is threatened to be made a
party to or is otherwise involved in any action, suit or proceeding, whether
civil, criminal, administrative, or investigative (hereinafter a "proceeding"),
by reason of the fact that he or she is or was a director or an officer of the
Corporation or is or was serving at the request of the Corporation as a
director, officer, employee, or agent of another corporation or of a
partnership, joint venture, trust, or other enterprise, including service with
respect to an employee benefit plan (hereinafter an "indemnitee"), whether the
basis of such proceeding is alleged action in an official capacity as a
director, officer,





                                     - 16 -
<PAGE>   17
employee, or agent or in any other capacity while serving as a director,
officer, employee, or agent, shall be indemnified and held harmless by the
Corporation to the fullest extent authorized by the corporation statutes of the
State of Nevada, as the same exists or may hereafter be amended (but, in the
case of any such amendment, only to the extent that such amendment permits the
Corporation to provide broader indemnification rights than such law permitted
the Corporation to provide prior to such amendment), against all expense,
liability and loss (including attorneys' fees, judgments, fines, ERISA excise
taxes, or penalties and amounts paid in settlement) reasonably incurred or
suffered by such indemnitee in connection therewith; provided, however, that,
except as provided in Section 3 of this Article VII with respect to proceedings
to enforce rights to indemnification, the Corporation shall indemnify any such
indemnitee in connection with a proceeding (or part thereof) initiated by such
indemnitee only if such proceeding (or part thereof) was authorized by the
Board of Directors of the Corporation.

Section 2.  Right to Advancement of Expenses.

         The right to indemnification conferred in Section 1 of this Article
VII shall include the right to be paid by the Corporation the expenses incurred
in defending any such proceeding in advance of its final disposition
(hereinafter an "advancement of expenses"); provided, however, that, if the
corporation statutes of the State of Nevada requires, an





                                     - 17 -
<PAGE>   18
advancement of expenses incurred by an indemnitee in his or her capacity as a
director or officer (and not in any other capacity in which service was or is
rendered by such indemnitee, including, without limitation, service to an
employee benefit plan) shall be made only upon delivery to the Corporation of
an undertaking (hereinafter an "undertaking"), by or on behalf of such
indemnitee, to repay all amounts so advanced if it shall ultimately be
determined by final judicial decision from which there is no further right to
appeal (hereinafter a "final adjudication") that such indemnitee is not
entitled to be indemnified for such expenses under this Section 2 or otherwise.
The rights to indemnification and to the advancement of expenses conferred in
Sections 1 and 2 of this Article VII shall be contract rights and such rights
shall continue as to an indemnitee who has ceased to be a director, officer,
employee, or agent and shall inure to the benefit of the indemnitee's heirs,
executors, and administrators.

Section 3.  Right of Indemnitee to Bring Suit.

         If a claim under Section 1 or 2 of this Article VII is not paid in
full by the Corporation within sixty (60) days after a written claim has been
received by the Corporation, except in the case of a claim for an advancement
of expenses, in which case the applicable period shall be twenty (20) days, the
indemnitee may at any time thereafter bring suit against the Corporation to
recover the unpaid amount of the claim.  If





                                     - 18 -
<PAGE>   19
successful in whole or in part in any such suit, or in a suit brought by the
Corporation to recover an advancement of expenses pursuant to the terms of an
undertaking, the indemnitee shall be entitled to be paid also the expense of
prosecuting or defending such suit.  In (i) any suit brought by the indemnitee
to enforce a right to indemnification hereunder (but not in a suit brought by
the indemnitee to enforce a right to an advancement of expenses) it shall be a
defense that, and (ii) in any suit brought by the Corporation to recover an
advancement of expenses pursuant to the terms of an undertaking, the
Corporation shall be entitled to recover such expenses upon a final
adjudication that, the indemnitee has not met any applicable standard for
indemnification set forth in the corporation statutes of the State of Nevada.
Neither the failure of the Corporation (including its Board of Directors,
independent legal counsel, or its stockholders) to have made a determination
prior to the commencement of such suit that indemnification of the indemnitee
is proper in the circumstances because the indemnitee has met the applicable
standard of conduct set forth in the corporation statutes of the State of
Nevada, nor an actual determination by the Corporation (including its Board of
Directors, independent legal counsel, or its stockholders) that the indemnitee
has not met such applicable standard of conduct, shall create a presumption
that the indemnitee has not met the applicable standard of conduct or, in the
case of such a suit brought by





                                     - 19 -
<PAGE>   20
the indemnitee, be a defense to such suit.  In any suit brought by the
indemnitee to enforce a right to indemnification or to an advancement of
expenses hereunder, or brought by the Corporation to recover an advancement of
expenses pursuant to the terms of an undertaking, the burden of proving that
the indemnitee is not entitled to the indemnified, or to such advancement of
expenses, under this Article VII or otherwise shall be on the Corporation.

Section 4.  Non-Exclusivity of Rights.

         The rights to indemnification and to the advancement of expenses
conferred in this Article VII shall not be exclusive of any other right which
any person may have or hereafter acquire under any statute, the Corporation's
Articles of Incorporation, Bylaws, agreement, vote of stockholders, or
disinterested directors or otherwise.

Section 5.  Insurance.

         The Corporation may maintain insurance, at its expense, to protect
itself and any director, officer, employee, or agent of the Corporation or
another corporation, partnership, joint venture, trust, or other enterprise
against any expense, liability or loss, whether or not the Corporation would
have the power to indemnify such person against such expense, liability or loss
under the corporation statutes of the State of Nevada.

expenses to any employee or agent of the Corporation to the fullest extent of
the provisions of this Article with respect to the indemnification and

reason of an increase in the number of Directors shall be filled by election at

notice shall be given, it shall not be construed to mean personal notice, but
any such notice may be given in writing by mail, postage prepaid, but any such

person, except that the President and the Corporate Secretary shall not be the
same person.  Each such executive officer shall have such authority and perform
such duties in the management of the corporation as may be prescribed by the
Senior Chairman or as determined by resolution of the Board of Directors.

other officers and agents as it shall deem necessary, who shall hold their
offices for such term and who shall have such authority and perform such duties
as may be prescribed by the Board of Directors or the Senior Chairman.  The

judgment the best interests of the corporation will be served thereby, but such
removal shall be without prejudice to the contract rights, if any, of the
person so removed.  Election or appointment of an officer or agent shall not of
itself create contract rights.

                 Section 5.  THE CHAIRMAN.  The Chairman shall have such powers
and responsibilities, and shall perform such duties, as delineated by the Board
or by the Senior Chairman.  He shall be directly responsible to the Senior
Chairman in such performance.  He shall, in the event of the absence or
inability to act of the President, be charged with the responsibilities of the
President.  If the Board of Directors does not elect a Senior Chairman, the
Chairman shall exercise the powers, duties and responsibilities given to the
Senior Chairman under Section 4 and other provisions of these Bylaws.

                 Section 6. THE PRESIDENT.  The President shall be the chief
operating officer of the corporation.  He shall have such powers and
responsibilities and shall perform such duties as delineated by the Board or by

for any purpose or purposes whatsoever, may be called at any time by the Board
of Directors, or by the Chairman, or by the President, or by one or more
shareholders holding shares in the aggregate entitled to cast not less than 10%
of the votes at any such meeting.

         If a special meeting is called by any person or persons other than the
Board of Directors, the Chairman or the President, the request shall be in
writing, specifying the time of such meeting and the general nature of the
business proposed to be transacted,





                                       2
<PAGE>   3
and shall be delivered personally or sent by registered mail or by telegraphic
or other facsimile transmission to the Chairman, the President, any Vice
President or the Corporate Secretary.  The officer receiving such request
forthwith shall cause notice to be given to the shareholders entitled to vote,
in accordance with the provisions of Sections 4 and 5 of this Article II, that
a meeting will be held at the time requested by the person or persons calling
the meeting, not less than thirty-five (35) nor more than sixty (60) days after
the receipt of the request.  If the notice is not given within twenty (20) days
after receipt of the request, the person or persons requesting the meeting may
give the notice.  Nothing contained in this paragraph of this Section 3 shall
be construed as limiting, fixing or affecting the time when a meeting of
shareholders called by action of the Board of Directors the Chairman, or the
President may be held.

         Section 4.  NOTICE OF SHAREHOLDERS' MEETINGS.  All notices of meetings
of shareholders shall be sent or otherwise given in accordance with Section 5
of this Article II not less than ten (10) nor more than sixty (60) days before
the date of the meeting being noticed.  The notice shall specify the place,
date and hour of the meeting and (i) in the case of a special meeting, the
general nature of the business to be transacted, or (ii) in the case of the
annual meeting, those matters which the Board of Directors, at the time of
giving the notice, intends to present for action by the shareholders.  The
notice of any meeting at which directors are to be elected shall include the
name of any nominee or nominees which, at the time of the notice, management
intends to present for election.

<PAGE>   4
         Section 5.  MANNER OF GIVING NOTICE; AFFIDAVIT OF NOTICE.  Notice of
any meeting of shareholders shall be given either personally or by first-class
mail or other means of written communication, addressed to the shareholder at
the address of such shareholder appearing on the books of the corporation or
given by the shareholder to the corporation for the purpose of notice.  If no
such address appears on the corporation's books or is given, notice shall be
deemed to have been. given if sent to the corporation's principal executive
office, or if published at least once in a newspaper of general circulation in
the county in which such office is located.  Notice shall be deemed to have
been given at the time when delivered personally or deposited in the mail or
sent by other means of written communication.

         If any notice addressed to a shareholder at the address of such
shareholder appearing on the books of the corporation is returned to the
corporation by the United States Postal Service marked to indicate that the
United States Postal Service is unable to deliver the notice to the shareholder
at such address, all future notices or reports shall be deemed to have been
duly given without further mailing if the same shall be available to the
shareholder upon written demand of the shareholder at the principal executive
office of the corporation for a period of one year from the date of the giving
of such notice.





                                       4
<PAGE>   5
         An affidavit of the mailing or other means of giving any notice of any
shareholders' meeting shall be executed by the Corporate Secretary, Assistant
Corporate Secretary or any transfer agent of the corporation giving such
notice, and shall be filed and maintained in the minute book of the
corporation.

         Section 6.  QUORUM.  The presence in person or by proxy of the holders
of a majority of the shares entitled to vote at any meeting of shareholders
shall constitute a quorum for the transaction of business.  The shareholders
present at a duly called or held meeting at which a quorum is present may
continue to do business until adjournment, notwithstanding the withdrawal of
enough shareholders to leave less than a quorum, if any action taken (other
than adjournment) is approved by at least a majority of the shares required to
constitute a quorum.

         Section 7.  ADJOURNED MEETING AND NOTICE THEREOF.  Any shareholders'
meeting, annual or special, whether or not a quorum is present, may be
adjourned from time to time by the vote of the majority of the shares
represented at such meeting, either in person or by proxy, but in the absence
of a quorum, no other business may be transacted at such meeting.

         When any meeting of shareholders, either annual or special, is
adjourned to another time or place, notice need not be given of the adjourned
meeting if the time and place thereof are announced at a meeting at which the
adjournment is taken, unless a new record date for the adjourned meeting is
fixed, or unless the adjournment is for more than forty- five (45) days from
the date set for the





                                       5
<PAGE>   6

original meeting, in which case the Board of Directors shall set a new record
date.  Notice of any such adjourned meeting shall be given to each shareholder
of record entitled to vote at the adjourned meeting in accordance with the
provisions of Sections 4 and 5 of this Article II.  At any adjourned meeting
the corporation may transact any business which might have been transacted at
the original meeting.

         Section 8.  VOTING.  Unless a record date for voting purposes is fixed
as provided in Section 1 of Article VIII of these Bylaws, then, subject to the
provisions of Section 702 to Section 704, inclusive, of the California
Corporations Code (the "Code"), only persons in whose names shares entitled to
vote stand on the stock records of the corporation at the close of business on
the business day next preceding the day on which notice is given (or, if notice
is waived, at the close of business on the business day next preceding the day
on which the meeting is held) shall be entitled to vote at such meeting.  Any
shareholder entitled to vote on any matter other than elections of directors or
officers, may vote part of the shares held by such person in favor of the
proposal and refrain from voting the remaining shares held by such person or
vote them against the proposal, but, if the shareholder fails to specify the
number of shares such shareholder is voting affirmatively, it will be
conclusively presumed that the shareholder's approving vote is with respect to
all shares such shareholder is entitled to vote.  Such vote may be by voice
vote or by ballot; provided, however, that all elections for directors must





                                       6
<PAGE>   7
be by ballot upon demand by a shareholder at any election and before the voting
begins.

         At a shareholders' meeting involving the election of directors, no
shareholder shall be entitled to cumulate votes (i.e., cast for any one or more
candidates a number of votes greater than the number of the shareholder's
shares) unless the names of such candidate(s) have been placed in nomination
prior to the voting and a shareholder has given notice prior to the voting of
the shareholder's intention to cumulate votes.  If any shareholder has given
such notice, then each shareholder entitled to vote may cumulate such
shareholder's votes for candidates in nomination and give one candidate a
number of votes equal to the number of directors to be elected multiplied by
the number of votes to which such shareholder's shares are entitled, or
distribute the shareholder's vote on the same principle among any or all of the
candidates, as the shareholder thinks fit.  The candidates receiving the
highest number of votes up to the number of directors to be elected shall be
elected.

         Section 9. WAIVER OF NOTICE OR CONSENT BY ABSENT SHAREHOLDERS.  The
transactions at any meeting of shareholders, either annual or special, however
called and noticed, and wherever held, shall be as valid as though had at a
meeting duly held after regular call and notice, if a quorum be present either
in person or by proxy, and if, either before or after the meeting, each person
entitled to vote, not present in person or by proxy, signs a written waiver of





                                       7
<PAGE>   8
notice or a consent to a holding of the meeting, or an approval of the minutes
thereof.

         Attendance of a person at a meeting shall also constitute a waiver of
notice of such meeting, except when the person objects, at the beginning of the
meeting, to the transaction of any business because the meeting is not lawfully
called or convened, and except that attendance at a meeting is not a waiver of
any right to object to the consideration of matters not included in the notice
if such objection is expressly made at the meeting.

         Section 10. SHAREHOLDER ACTION BY WRITTEN CONSENT WITHOUT A MEETING.
Any action which may be taken at any annual or special meeting of shareholders
may be taken without a meeting and without prior notice, if a consent in
writing, setting forth the action so taken, is signed by the holders of
outstanding shares having not less than the minimum number of votes that would
be necessary to authorize or take such action at a meeting at which all shares
entitled to vote thereon were present and voted.  In the case of election of
directors, such consents shall be effective only if signed by the holders of
all outstanding shares entitled to vote for the election of directors.  All
such consents shall be filed with the Corporate Secretary and shall be
maintained in the corporate records.  Any shareholder giving a written consent,
or the shareholder's proxy holders, or a transferee of the shares or a personal
representative of the shareholder or their respective proxy holders, may revoke
the consent by a writing received by the Corporate Secretary prior to the time
that written consents of the





                                       8
<PAGE>   9
number of shares required to authorize the proposed action have been filed with
the Corporate Secretary.

         If the consents of all shareholders entitled to vote have not been
solicited in writing, and if the unanimous written consent of all such
shareholders shall not have been received, the Corporate Secretary shall give
prompt notice of the corporate action approved by the shareholders without a
meeting.

         Section 11.  PROXIES.  Every person entitled to vote for directors or
on any other matter shall have the right to do so either in person or by one or
more agents authorized by a written proxy signed by the person and filed with
the Corporate Secretary.  A proxy shall be deemed signed if the shareholder's
name is placed on the proxy (whether by manual signature, typewriting,
telegraphic transmission or otherwise) by the shareholder or the shareholder's
attorney in fact.  A validly executed proxy which does not state that it is
irrevocable shall continue in full force and effect unless revoked by the
person executing it, prior to the vote pursuant thereto, by a writing delivered
to the corporation stating that the proxy is revoked or by a subsequent proxy
executed by, or attendance at the meeting and voting in person by the person
executing the proxy; provided, however, that no such proxy shall be valid after
the expiration of eleven (11) months from the date of such proxy, unless
otherwise provided in the proxy.

                                  ARTICLE III

                                   DIRECTORS

         Section 1.  POWERS.  Subject to the provisions of the Code and any
limitations in the Articles of Incorporation and these Bylaws relating to
action required to be approved by the shareholders or by the outstanding
shares, the business and affairs of the corporation shall be managed and all
corporate powers shall be exercised by or under the direction of the Board of
Directors.

         Without prejudice to such general powers, but subject to the same
limitations, it is hereby expressly declared that the directors shall have the
power and authority to:

                 (a)      Select and remove all officers, agents and employees
         of the corporation, prescribe such powers and duties for them as may
         not be inconsistent with law, with the Articles of Incorporation or
         these Bylaws, fix their compensation and require from them security
         for faithful service.

                 (b)      Change the principal executive office or the
         principal business office from one location to another; cause the
         corporation to be qualified to do business in any other state,
         territory, dependency or foreign country; cause the corporation to
         conduct business within or without the State of California; designate
         any place within or without the State of California for the holding of
         any shareholders' meeting or meetings, including annual meetings;
         adopt, make and use a corporate seal, and prescribe the forms of
         certificate of stock, and alter the form of such seal and of such





                                       10
<PAGE>   11
         certificates from time to time as in their judgment they may deem
         best, provided that such forms shall at all times comply with the
         provisions of law.

                 (c)      Authorize the issuance of shares of stock of the
         corporation from time to time, upon such terms as may be lawful, in
         consideration of money paid, labor done or services actually rendered,
         debts or securities canceled, tangible or intangible property actually
         received.

                 (d)      Borrow money and incur indebtedness for the purpose
         of the corporation, and cause to be executed and delivered therefor,
         in the corporate name, promissory notes, bonds, debentures, deeds of
         trust, mortgages, pledges, hypothecations, or other evidences of debt
         and securities therefor.

         Section 2.  NUMBER AND QUALIFICATION OF DIRECTORS.  The Board of
Directors shall consist of three directors.  Directors need not be shareholders
or residents of the State of California.

         Section 3. ELECTION AND TERM OF OFFICE OF DIRECTORS.  Directors shall
be elected at each annual meeting of the shareholders to hold office until the
next annual meeting, but if any such annual meeting is not held or the
directors are not elected at any annual meeting, the directors may be elected
at any special meeting of shareholders held for that purpose, or at the next
annual meeting of shareholders held thereafter.  Each director, including a
director elected to fill a vacancy, shall hold office until the expiration of
the term for which elected and until a successor has





                                       11
<PAGE>   12
been elected and qualified or until his earlier resignation or removal or his
office has been declared vacant in the manner provided in these Bylaws.

         Section 4.  RESIGNATION AND REMOVAL OF DIRECTORS.  Any director may
resign effective upon giving written notice to the Chairman, the President, the
Corporate Secretary or the Board of Directors, unless the notice specifies a
later time for the effectiveness of such resignation, in which case such
resignation shall be effective at the time specified.  Unless such resignation
specifies otherwise, its acceptance by the corporation shall not be necessary
to make it effective.  The Board of Directors may declare vacant the office of
a director who has been declared of unsound mind by an order of court or
convicted of a felony.  Any or all of the directors may be removed either for
or without cause if such removal is approved by the affirmative vote of a
majority of the outstanding shares entitled to vote, provided that no director
may be removed without cause (unless the entire Board is removed) when the
votes cast against removal (or, if such action is taken by written consent, the
shares held by persons not consenting in writing to such removal) would be
sufficient to elect such director if voted cumulatively at an election at which
the same total number of votes were cast (or, if such action is taken by
written consent, all shares entitled to vote were voted) and the entire number
of directors authorized at the time of the director's most recent election were
then being elected.  No reduction of the authorized





                                       12
<PAGE>   13
number of directors shall have the effect of removing any director before his
term of office expires.

         Section 5. VACANCIES.  Vacancies in the Board of Directors may be
filled by a majority of the remaining directors, though less than a quorum, or
by a sole remaining director, except that a vacancy created by the removal of a
director by the vote or written consent of the shareholders or by court order
may be filled only by approval of the shareholders.

         A vacancy in the Board of Directors exists as to any authorized
position of director which is not then filled by a duly elected director,
whether caused by death, resignation, removal, increase in the authorized
number of directors or otherwise.

         The shareholders may elect a director or directors at any time to fill
any vacancy or vacancies not filled by the directors, but any such election by
written consent shall require the consent of a majority of the outstanding
shares entitled to vote.  If the resignation of a director is effective at a
future time, the Board of Directors may elect a successor to take office when
the resignation becomes effective.

         Section 6.  PLACE OF MEETINGS.  Regular meetings of the Board of
Directors may be held at any place within or without the State of California as
shall from time to time be determined by the Board of Directors.  In the
absence of such designation, regular meetings shall be held at the principal
executive office of the corporation.  Special meetings of the Board shall be
held at any place within or without the State of California that has been
designated in the





                                       13
<PAGE>   14
notice of the meeting or, if not stated in the notice or if there is not
notice, at the principal executive office of the corporation.  Any meeting,
regular or special, may be held by conference telephone or similar
communication equipment, so long as all directors participating in such meeting
can hear one another, and all such directors shall be deemed to be present in
person at such meeting.

         Section 7. ANNUAL MEETINGS.  Immediately following each annual meeting
of shareholders, the Board of Directors shall hold a regular meeting for the
purpose of transaction of other business.  Notice of this meeting shall not be
required.

         Section 8. OTHER REGULAR MEETINGS.  Other regular meetings of the
Board of Directors shall be held at such time as shall from time to time be
fixed by the Board of Directors.  Such regular meetings may be held with or
without notice, provided that notice of any change in the time of any such
meetings shall be given to all of the directors.  Notice of a change in the
determination of the time shall be given to each director in the same manner as
notice for special meetings of the Board of Directors.

         Section 9.  SPECIAL MEETINGS.  Special meetings of the Board of
Directors for any purpose or purposes may be called at any time by the Chairman
or the President or any director.

         Notice of the time and place of special meetings shall be delivered
personally or by telephone to each director or sent by first-class mail or
telegram, charges prepaid, addressed to each director at his or her address as
it is shown upon the records of





                                       14
<PAGE>   15
the corporation.  In case such notice is mailed, it shall be deposited in the
United States mail at least four (4) days prior to the time of the holding of
the meeting.  In case such notice is delivered personally, or by telephone or
telegram, it shall be delivered personally or by telephone or to the telegraph
company at least forty-eight (48) hours prior to the time of the holding of the
meeting.  Any oral notice given personally or by telephone may be communicated
to either the director or to a person at the office of the director who the
person giving the notice has reason to believe will promptly communicate it to
the director.  The notice need not specify the purpose of the meeting nor the
place if the meeting is to be held at the principal executive office of the
corporation.

         Section 10.  QUORUM.  A majority of the authorized number of directors
shall constitute a quorum for the transaction of business, except to adjourn as
hereinafter provided.  Every act or decision done or made by a majority of the
directors present at a meeting duly held at which a quorum is present shall be
regarded as the act of the Board of Directors.  A meeting at which a quorum is
initially present may continue to transact business notwithstanding the
withdrawal of directors, if any action taken is approved by at least a majority
of the required quorum for such meeting.

         Section 11.  WAIVER OF NOTICE.  The transactions of any meeting of the
Board of Directors, however called and noticed or wherever held, shall be as
valid as though had at a meeting duly held after regular call and notice if a
quorum be present and if,





                                       15
<PAGE>   16
either before or after the meeting, each of the directors not present signs a
written waiver of notice, a consent to holding the meeting or an approval of
the minutes thereof.  The waiver of notice or consent need not specify the
purpose of the meeting.  All such waivers, consents and approvals shall be
filed with the corporate records or made a part of the minutes of the meeting.
Notice of a meeting shall also be deemed given to any director who attends the
meeting without protesting, prior thereto or at its commencement, the lack of
notice to such director.

         Section 12.  ADJOURNMENT.  A majority of the directors present,
whether or not constituting a quorum, may adjourn any meeting to another time
and place.

         Section 13.  NOTICE OF ADJOURNMENT.  Notice of the time and place of
holding an adjourned meeting need not be given, unless the meeting is adjourned
for more than twenty-four (24) hours, in which case notice of such time and
place shall be given prior to the time of the adjourned meeting, in the manner
specified in Section 8 of this Article III, to the directors who were not
present at the time of the adjournment.

         Section 14.  ACTION WITHOUT MEETING.  Any action required or permitted
to be taken by the Board of Directors may be taken without a meeting, if all
members of the Board shall individually or collectively consent in writing to
such action.  Such action by written consent shall have the same form and
effect as a unanimous vote of the Board of Directors.  Such written consent or
consents shall be filed with the minutes of the proceedings of the Board.





                                       16
<PAGE>   17
         Section 15.  FEES AND COMPENSATION OF DIRECTORS.  Directors and
members of committees may receive such compensation, if any, for their
services, and such reimbursement of expenses, as may be fixed or determined by
resolution of the Board of Directors.  Nothing herein contained shall be
construed to preclude any director from serving the corporation in any other
capacity as an officer, agent, employee or otherwise, and receiving
compensation for such services.

                                   ARTICLE IV

                                   COMMITTEES

resolution adopted by a majority of the authorized number of directors,
designate one or more committees, each consisting of two or more directors, to
serve at the pleasure of the Board.  The Board may designate one or more
directors as alternate members of any committee, who may replace any absent
member at any meeting of the committee.  Any such committee, to the extent
provided in the resolution of the Board shall have all the authority of the
Board, except with respect to:

                 (a)      the approval of any action which, under the Code must
         be approved by the shareholders or approved by the outstanding shares;

                 (b)      the filling of vacancies on the Board of Directors or
         in any committee;

                 (c)      the fixing of compensation of the directors for
         serving on the Board or on any committee;

<PAGE>   18
                 (d)      the amendment or repeal of Bylaws or the adoption of
         new Bylaws;

                 (e)      the amendment or repeal of any resolution of the
         Board of Directors which by its express terms is not so amendable or
         repealable;

                 (f)      a distribution to the shareholders of the corporation,
         except at a rate or in a periodic amount or within a price range
         determined by the Board of Directors;

                 (g)      the appointment of any other committees of the Board
         of Directors or the members thereof.

         Section 2.  MEETINGS AND ACTION OF COMMITTEES.  Meetings and action of
committees shall be governed by, and held and taken in accordance with, the
provisions of Article III, Sections 6 (place of meetings), 8 (other regular
meetings), 9 (special meetings), 10 (quorum), 11 (waiver of notice), 12
(adjournment), 13 (notice of adjournment) and 14 (action without meeting), with
such changes in the context of those bylaws as are necessary to substitute the
committee and its members for the Board of Directors and its members, except
that the time of regular meetings of committees may be determined by resolution
of the Board of Directors as well as of the committee.  Special meetings of
committees may also be called by resolutions of the Board of Directors.  Notice
of special meetings of committees shall also be given to all alternate members,
who shall have the right to attend all meetings of the committee.  The Board of
Directors may adopt rules for the





                                       18
<PAGE>   19
government of any committee not inconsistent with the provisions of these
Bylaws.

<PAGE>   20
         Any officer may resign at any time by giving written notice to the
corporation.  Any such resignation shall take effect at the date of the receipt

                                   ARTICLE VI

               INDEMNIFICATION OF DIRECTORS, OFFICERS, EMPLOYEES,
                                AND OTHER AGENTS

         Section 1.  INDEMNIFICATION OF DIRECTORS AND CERTAIN OFFICERS.  The
corporation shall, to the maximum extent and in the manner permitted by the
Code indemnify each of its directors and its Chairman, President, Vice
Presidents, General Counsel, Controller, Treasurer, Corporate Secretary and
chief financial officer against expenses (as defined in Section 317(a) of the
Code), judgments, fines, settlements, and other amounts actually and reasonably
incurred in connection with any proceeding (as defined in Section 317(a) of the
Code), arising by reason of the fact that such person is or was an agent of the
corporation.  For purposes of this Article VI, a "director" of the corporation
includes any person who (i) is or was a director of the corporation, (ii) is or
was serving at the request of the corporation as a director or officer of
another corporation, partnership, joint venture, trust or other enterprise, or
(iii) was a director of a corporation which was a predecessor corporation of
the corporation or of another enterprise at the request of such predecessor
corporation.

         Section 2.  INDEMNIFICATION OF OTHERS.  The corporation shall have the
power, to the extent and in the manner permitted by the Code, to indemnify each
of its officers, employees, and agents (other than the directors and officers
specified in Section 1 of this Article against expenses (as defined in Section
317 (a) of the Code), judgments, fines, settlements, and other amounts actually
and reasonably incurred in connection with any proceeding (as





                                       24
<PAGE>   25
defined in Section 317(a) of the Code), arising by reason of the fact that such
person is or was an agent of the corporation, provided that the person acted in
good faith and in a manner the person believed to be in the best interests of
the corporation, and, in the case of a criminal proceeding, had no reasonable
cause to believe that the conduct of the person was unlawful.  For purposes of
this Article VI, an "employee" or "agent" of the corporation (other than the
directors or officers specified in Section 1 of this Article) includes any
person who (i) is or was an employee, officer, or agent of the corporation,
(ii) is or was serving at the request of the corporation as an employee,
officer or agent of another corporation, partnership, joint venture, trust or
other enterprise, or (iii) was an employee, officer or agent of a corporation
which was a predecessor corporation of the corporation or of another enterprise
at the request of such predecessor corporation.

         Section 3.  PAYMENT OF EXPENSES IN ADVANCE.  Expenses incurred in
defending any civil or criminal action or proceeding for which indemnification
is required pursuant to Section 1 or for which indemnification is permitted
pursuant to Section 2 following authorization thereof by the Board of Directors
shall be paid by the corporation in advance of the final disposition of such
action or proceeding upon receipt of an undertaking by or on behalf of the
indemnified party to repay such amount if it shall ultimately be determined
that the indemnified party is not entitled to be indemnified as authorized in
this Article VI.





                                       25
<PAGE>   26

         Section 4.  INDEMNITY NOT EXCLUSIVE.  The indemnification provided by
this Article VI shall not be deemed exclusive of any other rights to which
those seeking indemnification may be entitled under any bylaw, agreement, vote
of shareholders, or disinterested directors or otherwise, both as to action in
an official capacity and as to action in another capacity while holding such
office or position, to the extent that such additional rights to
indemnification are authorized in the Articles of Incorporation.

         Section 5.  INSURANCE.  The corporation shall have the power to
purchase and maintain insurance on behalf of any person who is or was a
director, officer, employee or agent of the corporation against any
liability asserted against or incurred by such person in such capacity or
arising out of such person's status as such, whether or not the corporation
would have the power to indemnify him against such liability under the
provisions of this Article VI.

         Section 6.  CONFLICTS.  No indemnification or advance shall be made
under this Article VI, except where such indemnification or advance is mandated
by law or the order, judgment or decree of any court of competent jurisdiction,
in any circumstance where it appears:

                 (a)      That it would be inconsistent with a provision of the
         Articles of Incorporation, these Bylaws, a resolution of the
         shareholders or an agreement in effect at the time of the accrual of
         the alleged cause of the action asserted in the proceeding in which
         the expense were incurred or other amounts





                                       26
<PAGE>   27
         were paid, which prohibits or otherwise limits indemnification; or

                 (b)      That it would be inconsistent with any condition
         expressly imposed by a court in approving a settlement.

         Section 7.  AMENDMENT.  The provisions of this Article relating to
indemnification shall constitute a contract between the corporation and each of
its directors and officers entitled to such indemnification hereunder which may
be modified as to any director or officer only with that person's consent or as
specifically provided in this Section.  Notwithstanding any other provision of
these Bylaws relating to their amendment generally, any repeal or amendment of
this Article which is adverse to any director or officer shall apply to such
director or officer only on a prospective basis and shall not limit the rights
of an indemnitee to indemnification with respect to any action or failure to act
occurring prior to the time of such repeal or amendment.  Notwithstanding any
other provision of these Bylaws, no repeal or amendment of these Bylaws shall
affect any or all of this Article so as to limit or reduce the indemnification
in any manner unless adopted by (a) the unanimous vote of the directors of the
corporation then serving, or (b) by the shareholders; provided that no such
amendment shall have retroactive effect inconsistent with the preceding
sentence.

         Section 8.  CHANGES IN CALIFORNIA LAW.  References in this Article to
the Code or to any provision thereof shall be to such law as it existed on the
date this Article was adopted or as such





                                       27
<PAGE>   28
law thereafter may be changed; provided that (a) in the case of any change
which expands the liability of directors or officers or limits the
indemnification rights or the rights to advancement of expenses which the
corporation may provide, the rights to limited liability, to indemnification
and to the advancement of expenses provided in the corporation's Articles of
Incorporation and/or these Bylaws shall continue as theretofore to the extent
permitted by law; and (b) if such change permits the corporation, without the
requirement of any further action by shareholders or directors, to limit
further the liability of directors (or limit the liability of officers) or to
provide broader indemnification rights or rights to the advancement of expenses
than the corporation was permitted to provide prior to such change, then
liability thereupon shall be so limited and the rights to indemnification and
the advancement of expenses shall be so broadened to the extent permitted by
law.

                                  ARTICLE VII

                              RECORDS AND REPORTS

         Section l.  MAINTENANCE AND INSPECTION OF SHARE REGISTER.  The
corporation shall keep at its principal executive office, or at the office of
its transfer agent or registrar, if either be appointed and as determined by
resolution of the Board of Directors, a record of its shareholders, giving the
names and addresses of all shareholders and the number and class of shares held
by each shareholder.

         A shareholder or shareholders of the corporation holding at least five

days prior written demand upon the corporation, and/or (ii) obtain from the
transfer agent of the corporation, upon written demand and upon the tender of
such transfer agent's usual charges for such list, a list of the shareholders'
names and addresses, who are entitled to vote for the election of directors,
and their shareholdings, as of the most recent record date for which such list
has been compiled or as of a date specified by the shareholder subsequent to
the date of demand.  Such list shall be made available by the transfer agent on
or before the later of (i) five (5) days after the demand is received, or (ii)
the date specified in the request as the date as of which the list is to be
compiled.

         Section 2.  MAINTENANCE OF BYLAWS.  The corporation shall keep at its
principal executive office, or, if its principal executive office is not in the
State of California, at its principal business office in the State of
California, the original or a copy of these Bylaws as amended to date.

         Section 3.  ANNUAL REPORT TO SHAREHOLDERS.  The annual report to
shareholders referred to in Section 1501 of the Code is expressly dispensed
with, but nothing herein shall be interpreted as prohibiting the Board of
Directors from issuing annual or other periodic reports to the shareholders of
the corporation as they deem appropriate.

wording payable to a bank or depository for credit to the account of the
corporation, is hereby authorized, and such checks shall require no signature
other than the name of the corporation printed at the lower right corner; and
further provided that checks,

Accounts, Depository Bank Accounts, and Special Bank Accounts of the
corporation shall be valid and enforceable according to its wording, tenor and

                                   ARTICLE IX

                           GENERAL CORPORATE MATTERS

         Section 1.  RECORD DATE.  For purposes of determining the shareholders
entitled to notice of any meeting or to vote or entitled to receive payment of
any dividend or other distribution or allotment of any rights or entitled to
exercise any rights in respect of any other lawful action, the Board of
Directors may fix, in advance, a record date, which shall not be more than
sixty (60) days not less than ten (10) days prior to the date of any such
meeting nor more than sixty (60) days prior to any other action, and in such
case only shareholders of record on the date so fixed are entitled to notice
and to vote or to receive the dividend, distribution or allotment of rights or
to exercise the rights, as the case may be, notwithstanding any transfer of any
shares on the books of the corporation after the record date fixed as
aforesaid, except as otherwise provided in the Code.

         If the Board of Directors does not so fix a record date:

                 (a)      The record date for determining shareholders entitled
         to notice of or to vote at a meeting of shareholders shall be at the
         close of business on the business day next preceding the day on which
         notice is given or, if notice is waived, at the close of business on
         the business day next preceding the day on which the meeting is held.

                 (b)      The record date for determining shareholders entitled
         to give consent to corporate action in writing without a meeting, when
         no prior action by the Board has been





                                       33
<PAGE>   34
         taken, shall be the day on which the first written consent is given.

                 (c)      The record date for determining shareholders for any
         other purpose shall be at the close of business on the day on which
         the Board adopts the resolution relating thereto, or the sixtieth
         (60th) day prior to the date of such other action, whichever is later.

         Section 2.  NOTES AND OTHER EVIDENCES OF INDEBTEDNESS.  All notes or
other evidences of indebtedness issued in the name of or payable by the
corporation shall be signed by the President or any Vice President and by the
Treasurer or any Assistant Treasurer, or by such other person or persons and in
such manner as, from time to time, shall be determined by resolution of the
Board of Directors.

         Section 3.  CORPORATE CONTRACTS AND INSTRUMENTS: HOW EXECUTED.  The
Board of Directors, except as in the Bylaws otherwise provided, may authorize
any officer or officers, agent or agents, to enter into any contract or execute
any instrument in the name of and on behalf of the corporation, and such
authority may be general or confined to specific instances; and, unless so
authorized or ratified by the Board of Directors or within the agency power of
an officer, no officer, agent or employee shall have any power or authority to
bind the corporation by any contract or engagement or to pledge its credit or
to render it liable for any purpose or to any amount.

         Section 4.  STOCK CERTIFICATES.  A certificate or certificates for
shares of the capital stock of the corporation shall be issued





                                       34
<PAGE>   35
to each shareholder when any such shares are fully paid, and the Board of
Directors may authorize the issuance of certificates or shares as partly paid
provided that such certificates shall state the amount of the consideration to
be paid therefor and the amount paid thereon.  All certificates shall be signed
in the name of the corporation (i) by the Chairman, the President or a Vice
President, and (ii) by the chief financial officer or Treasurer or any
Assistant Treasurer or the Corporate Secretary or any Assistant Corporate
Secretary, certifying the number of shares and the class or series of shares
owned by the shareholder.  Any or all of the signatures on the certificate may
be facsimile.  In case any officer, transfer agent, or registrar who has signed
or whose facsimile signature has been placed upon a certificate shall have
ceased to be such officer, transfer agent or registrar before such certificate
is issued, it may be issued by the corporation with the same effect as if such
person were an officer, transfer agent or registrar at the date of issue.

         Any such certificate shall also contain such legend or other statement
as may be required by Section 418 of the Code, the Corporate Securities Law of
1968, any other state or federal securities law or any agreement between the
corporation and the issuer thereof, and may contain such legend or other
statement as may be required by any other applicable law or regulation or
agreement.

         No new certificate for shares shall be issued in place of any
certificate theretofore issued unless the latter is surrendered and





                                       35
<PAGE>   36
canceled at the same time; provided, however, that a new certificate may be
issued without the surrender and cancellation of the old certificate if the
certificate theretofore issued is alleged to have been lost, stolen or
destroyed.  In case of any such allegedly lost, stolen or destroyed
certificate, the corporation may require the owner thereof or the legal
representative of such owner to give the corporation a bond (or other adequate
security) sufficient to indemnify it against any claim that may be made against
it (including any expense or liability) on account of the alleged loss, theft
or destruction of any such certificate or the issuance of such new certificate.

         Section 5.  LOST CERTIFICATES.  Except as hereinafter in this Section
provided, no new certificates for shares shall be issued in lieu of an old
certificate unless the latter is surrendered to the corporation and canceled at
the same time.  The Board of Directors may in case any share certificate or
certificate for any other security is lost, stolen, or destroyed, authorize the
issuance of a new certificate in lieu thereof, upon such terms and conditions
as the Board may require including provision for indemnification of the
corporation against any claim that may be made against it, including any
expense or liability, on account of the alleged loss, theft, or destruction of
such certificate or the issuance of such new certificate.

         Section 6.  REPRESENTATION OF SHARES OF OTHER CORPORATIONS.  The
Chairman, the President, any Vice President, or any other person authorized by
resolution of the Board of Directors is





                                       36
<PAGE>   37
authorized to vote on behalf of the corporation any and all shares of any other
corporation or corporations, foreign or domestic, standing in the name of the
corporation.  The authority herein granted to said officers or other persons to
vote or represent on behalf of the corporation any and all shares held by the
corporation in any other corporation or corporations may be exercised either in
person or by duly executed proxy.

         Section 7.  CONSTRUCTION AND DEFINITIONS.  Unless the context requires
otherwise, the general provisions, rules of construction, and definitions in
the Code shall govern the construction of these Bylaws.  Without limiting the
generality of the foregoing, the singular number includes the plural, the
plural number includes the singular, and the term "person" includes both a
corporation and a natural person.

these Bylaws may be amended or repealed by the affirmative vote of a majority
of the shares entitled to vote, or by the written consent of shareholders
entitled to vote such shares, except as otherwise provided by law or by the

required, in which case such express provision shall govern and control the

         Section 2.  The Board of Directors shall consist of such number
between three and twelve Directors as shall be determined by the shareholders.

meeting.  Any vacancy occurring in the Board of Directors may be filled by the
affirmative vote of a majority of the remaining Directors even though such
remaining Directors shall be less than a quorum of the Board of Directors.  A
Director elected to fill a vacancy shall be elected for the unexpired term of
his predecessor in office.  Any directorship to be filled by reason of an
increase in the number of Directors shall be filled by election at an annual
meeting or at a special meeting of shareholders called for that purpose.

                       MEETINGS OF THE BOARD OF DIRECTORS

of Shareholders, and





                                     - 7 -

by the President or his designee on three days' notice to each Director, either
personally or by mail or by telegram.  Neither the business to be transacted
at, nor the purpose of, any special meeting need be specified in a notice or
waiver of notice.

         Section 9.  At all meetings of the Board of Directors the presence of
a majority of the Directors shall constitute a quorum for the transaction of
business and the act of a majority of the Directors present at any meeting at
which there is a quorum shall be the act of the Board of Directors.  Any action
required or permitted to be taken at a meeting of the Board of Directors may be
taken without a meeting if a consent in writing, setting forth the action so
taken, is signed by all members of the Board of Directors.  If a quorum shall
not be present at any meeting of Directors, the Directors present thereat may
adjourn the meeting from time to time, without notice other than announcement
at the meeting, until a quorum shall be present.

party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative

by reason of the fact that he is or was a director, officer, employee or agent
of the corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, against expenses (including attorneys
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by him in connection with such actions, suit or proceeding if he acted
in good faith and in a manner he reasonably believed to be in or not opposed to

or proceeding, had no reasonable cause to believe his conduct was unlawful.
The termination of any action, suit or proceeding by judgment, order,
settlement, conviction, or upon a plea of nolo contendere or its equivalent,
shall not, of itself, create a presumption that the person did not act in good
faith and in a manner which he reasonably believed to be in or not opposed to

or proceeding, had reasonable cause to believe that his conduct was unlawful.

         Section 2.  The corporation shall indemnify any person who was or is a
party or is threatened to be made a party to any threatened, pending or
completed action or suit by or in the right of the corporation to procure a
judgment in its favor by reason of the fact that he is or was a director,
officer, employee or agent of the corporation, or is or was serving at the
request of the corporation as a director, officer, employee or agent of the
corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, against expenses
(including attorneys' fees) actually and reasonably incurred by him in
connection with the defense or settlement of such action or suit if he acted in
good faith and in a manner he reasonably believed to be in or not opposed to
the best interests of the corporation; provided, however, that no
indemnification shall be made in respect to any claim, issue or matter as to
which such person shall have been adjudged to be liable to the corporation
except to the extent that the court in which such action or suit was brought
shall determine upon application that, despite the adjudication of liability
but in view of all circumstances of the case, such person is fairly and
reasonably entitled to indemnity for such expenses which such court shall deem
proper.

         Section 3.  To the extent that a director, officer, employee or agent
of the corporation has been successful on the merits or otherwise in defense of
any action, suit or

         Section 4.  Any indemnification under Sections 1 and 2 (unless ordered
by a court) shall be made by the corporation only as authorized in the specific
case upon a determination that indemnification of the director, officer,
employee or agent is proper in the circumstances because he has met the
applicable standard of conduct set forth in Sections 1 and 2. Such
determination shall be made (a) by the Board of Directors by a majority vote of
a quorum consisting of directors who were not parties to such action, suit or
proceeding, or (b) if such a quorum is not obtainable, or, even if obtainable a
quorum of disinterested directors so directs, by independent legal counsel in a
written opinion, or (c) by the stockholders.

receipt of an undertaking by or on behalf of such director or officer to repay
such amount if it shall ultimately be determined that he is not entitled to be
indemnified by the corporation as authorized in this Article.  Such expenses
incurred by other employees and agents may be so paid upon





                                     - 25 -

such terms and conditions, if, any, as the Board of Directors deems
appropriate.

         Section 6.  The indemnification and advancement of expenses provided
by or granted pursuant to, the other Sections of this Article shall not be
deemed exclusive of any other rights to which those seeking indemnification or
advancement of expenses may be entitled under any agreement, vote of
stockholders or disinterested directors or otherwise, both as to action in his
official capacity and as to action in another capacity while holding such
office.

         Section 7.  The indemnification and advancement of expenses provided
by, or granted pursuant to, this Article shall, unless otherwise provided when

insurance on behalf of any person who is or was a director, officer, employee
or agent of the corporation, or is or was serving at the request of the
corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise against any liability
asserted against him and incurred by him in any such capacity, or arising out
of his status as such, whether or not the corporation would have





                                     - 26 -
<PAGE>   27
the power to indemnify him against such liability under the provisions of this
Article.

         Section 9.  For purposes of this Article, references to "the
corporation" shall include, in addition to the resulting corporation, any
constituent corporation (including any constituent of a constituent) absorbed
in a consolidation or merger which, if its separate existence had continued,
would have had power and authority to indemnify its directors, officers, and
employees or agents, so that any person who is or was a director, officer,
employee or agent of such constituent corporation, or is or was serving at the
request of such constituent corporation as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise, shall stand in the same position under the provisions of this
Article with respect to the resulting or surviving corporation as he would have
with respect to such constituent corporation if its separate existence had
continued.

enterprises" shall include employee benefit plans; references to "fines" shall
include any excise taxes assessed on a person with respect to an employee
benefit plan; and references to "serving at the request of the corporation"

opposed to the best interests of the corporation" as referred to in this
Article.

determined, an appropriate supplemental amount shall be contributed or an
appropriate amount refunded.  The initial balance of the capital account of the
General Partner shall be an amount equal to such contribution by the General
Partner and adjusted appropriately in accordance with the foregoing.

5.2      Limited Partner.

                 On or before December 31, 1996, the Limited Partner will

accounts have been made, if the General Partner then has a negative balance in
its capital account, it shall contribute to the Partnership an amount of cash

hereby waive compliance with all provisions of the Act granting a right to a
return of their contributions other than as provided in this Agreement.

                 The Limited Partner and the General Partner may, but are not
obligated to, extend loans to the Partnership at the request of the General
Partner upon such terms and conditions as may be agreed to between the lending
Partner and the Partnership.  The General Partner shall have the full and
exclusive authority in determining whether borrowed funds are required for the
continued operation of the Partnership and negotiating the terms and conditions
of any loans obtained by the Partnership from the General Partner of the
Limited Partner.  Nothing contained in this Section shall imply that any
Partner has any liability or obligation whatsoever to loan any funds to the
Partnership at any time.

                            VI.  PROFITS AND LOSSES

6.1      Allocations in General.

                 Subject to the provisions of the Code pertaining to
allocations, all items of Partnership losses, deductions, income and gain for

the ratios of the Partners'





                                       11
<PAGE>   12
respective Percentage Interests; provided, however, that losses shall be
allocated among the Partners who have positive balances in their capital
accounts, in proportion to those balances and to the extent of such balances,
and any additional losses in any year shall be allocated among the Partners who
have positive balances in their capital accounts, in proportion to those
balances and to the extent of such balances, and any additional losses in any
year shall be allocated to the General Partner.

6.2      Transferor-Transferee Allocations.

                 If a Partnership Interest is transferred during any year, the
income, gains losses, and deductions allocable in respect of that Partnership
Interest shall be prorated between the transferor and the transferee on the
basis of the number of days in the year that each was the holder of that
interest without regard to the results of the Partnership operations (or cash
distributions made) during the period before and after the transfer unless the
transferor and transferee agree to an allocation based on the results as of the
record date of transfer and agree to reimburse the Partnership for the cost of
making and reporting their agreed allocation.  Notwithstanding the foregoing,
no allocation shall be made which is not allowed by Section 706(d) of the Code.

6.3      Section 751 Assets.

                 In the event of any transfer or redemption of a Partnership
Interest, the General Partner shall provide the parties with the amount of
Partnership assets described in

<PAGE>   13
Section 751 of the Code as of the date of such transfer or redemption.  Each of
the parties to any such transfer or redemption agrees to report such
transaction on its own federal income tax returns consistent with such
information supplied by the General Partner.

6.5      Compliance with Code.

                 The foregoing provisions and the other provisions of this
Agreement are intended to comply with the Code, including but not limited to
Sections 701 through 709 thereof, and shall be interpreted and applied in a
manner consistent therewith.  If the General Partner determines that it is
prudent to modify the manner in which the capital accounts are computed or
maintained or the allocations are made in order to comply with the Code.  The
General Partner may make such modification.

                            VII.  CASH DISTRIBUTIONS

7.1      Distributable Cash.

                 Subject to the remaining portion of this Section 7.1 and the
other provisions of this Agreement, all or part of Distributable Cash may be
distributed at the sole discretion of the General Partner among the Partners
according to their Percentage Interests.  "Distributable Cash" means, at the
time of determination, all Partnership cash derived from the conduct of the
Partnership's business, other than (i) capital contributions of the Partners,
(ii) financing proceeds, (iii) reserves for working capital, and (iv) other
amounts that the General Partner





                                       13
<PAGE>   14
reasonably determines to be necessary for the proper operation of the
Partnership's business.

                 With regard to Distributable Cash, the General Partner shall
make a determination in accordance with its duty of care and loyalty to the
Partnership as to the need for the funds in the operation of the Partnership
business, considering both current needs for operating capital, prudent
reserves for future operating capital, current investment opportunities, and
prudent reserves for future investment opportunities, all in keeping with the
Partnership purposes.  It is the duty of the General Partner, in determining
the amount of Distributable Cash available for the payment necessary in the
operation of its business until the income from further operations is
available, the amount of its debts, the necessity or advisability of paying its
debts, or at least reducing them within the limits of the Partnership's credit,
the preservation of the Partnership's assets, and the character of its surplus
assets.  Any contributed property or borrowed funds by the Partnership shall be
considered as needed for Partnership investment purposes, and any cash
produced from the sale of property, including the portion of the sale proceeds
representing capital appreciation, shall be considered as needed reserves for
Partnership investment purposes.  All or part of Distributable Cash may, to the
extent deemed unnecessary for Partnership purposes by the General Partner under
the foregoing standard, be distributed in accordance with this Agreement.





                                       14

made to the Partners in the ratios of their respective Percentage Interests.

                 (b)      Distributions during winding up shall be made as set
forth in Section 10.2.

furtherance of the interests of the Partnership, including, but not limited to,

<PAGE>   8



respective Percentage Interests; provided, however, that losses shall be

intended to comply with the Code, including but not limited to Sections 701
through 709 thereof, and shall be interpreted and applied in a manner consistent

7.1      Distributable Cash.

         Subject to the remaining portion of this Section 7.1 and the other
provisions of this Agreement, all or part of Distributable Cash may be
distributed at the sole discretion of the General Partner among the Partners
according to their Percentage Interests. "Distributable Cash" means, at the
time of determination, all Partnership cash derived from the conduct of the
Partnership's business, other than (i) capital contributions of the Partners,
(ii) financing proceeds, (iii) reserves for working capital, and (iv) other
amounts that the General Partner reasonably determines to be necessary for the
proper operation of the Partnership's business.

         With regard to Distributable Cash, the General Partner shall make a
determination in accordance with its duty of care and loyalty to the Partnership
as to the need for the funds in the operation of the Partnership business,
considering both current needs for operating capital, prudent reserves for
future operating, capital, current investment opportunities, and prudent
reserves for future investment opportunities, all in keeping with the
Partnership purposes. It is the duty of the General Partner, in determining the
amount of Distributable Cash available for the payment necessary in the
operation of its business until the income from further operations is available,
the amount of its debts, the necessity or advisability of paying its debts, or
at least reducing them within the limits of the Partnership's credit, the
preservation of the Partnership's assets, and the character of its surplus
assets. Any contributed property or borrowed funds by the Partnership shall be
considered as needed for Partnership investment purposes, and any cash produced
from the sale of property, including the portion of the sale proceeds
representing capital appreciation, shall be considered as needed reserves for
Partnership investment purposes. All or part of Distributable Cash may, to the
extent deemed unnecessary for Partnership purposes by the General Partner under
the foregoing standard, be distributed in accordance with this Agreement.

7.2      Distributions of Distributable Cash.

         (a) All distributions made prior to winding up shall be made to the
    Partners in the ratios of their respective Percentage Interests.

         (b) Distributions during winding up shall be made as set forth in
    Section 10.2.

                           (d) The Limited Partner additionally agrees to
                           contribute to the Partnership, immediately upon
                           receipt, all of the assets, and the Partnership will
                           simultaneously assume all of the liabilities and
                           other obligations, that are reflected on Exhibit
                           "A-3" attached hereto. The balance of the capital
                           account of the Limited Partner shall thereupon be

notice may be given in writing, by mail, addressed to such Director or
shareholder at such address as appears on the books of the corporation.  Any

         5.2  Series of Stock.  The Board of Directors may divide any class of
shares into series and may fix and determine the relative attributes of series
so established, as follows:

         A.      The number of designation of series of shares in any class and
the number of shares in any series, provided that no allotted shares, except in
the exercise of conversion rights, be shifted from one series or class to
another series or class, or otherwise have their attributes altered.

         B.      The dividend rate of any unallotted shares of any series or
class.

         C.      The terms and conditions of conversion of any unallotted
convertible shares of any class or series.

         D.      The redemptive price and terms and conditions of redemption of
any unallotted shares of any series or class.

         E.      The liquidation price of any unallotted shares of any series
or class.

         5.3  Limitations as to Stock.  The Board shall not create a sinking
fund in respect to any series unless provisions for a sinking fund, at least as
beneficial to all allotted shares of the same class, shall either then exist or
at that time be created or provided for.  At least one class of shares shall
have full voting privileges, except as limited or restricted by voting
privileges contingently or temporarily conferred upon some other class or
classes of shares.  All shares of any one class shall have the same voting
privileges and restrictions, unless a class be divided into series; and in such
case, all the shares of any one series shall have the same voting rights,
preferences, privileges, and restrictions.  No shares, with or without par
value, shall be allotted by such corporation except in consideration of money or
property, including intangibles actually received, labor or services actually
surrendered, cancelled, or reduced, or funds or other assets transferred from
surplus to stated capital upon the allotment of a share dividend.  The Board of
Directors shall determine and state by resolution in monetary terms the fair
value to the corporation of any consideration other than money for which such
shares are allotted.  Shares for which the consideration shall have been
received, performed or surrendered to the corporation shall be fully paid and
non-assessable.  The Directors may allot shares having par value for such
consideration not less than the par value thereof, as shall be fixed from time
to time by the Board of Directors.

under the By-laws or any amendment or change thereto; provided, however, that
the number of Directors of the Corporation shall at no time be less than three

this regard shall at all times be subject to the rights of the shareholders to
alter or repeal such By-laws at any annual meeting of shareholders, and the
power of the Board of Directors shall not extend to any amendment of the
By-laws respecting the number, qualifications, classifications, or terms of
office of the members of the Board of Directors.

         9.2  Transactions Involving Related Parties.  No contract or other
transaction between this Corporation, whether or not a majority of shares of
the capital stock of such other corporation is owned by this corporation, and
no act of this Corporation shall in any way be affected by the fact that any of
the Directors of this Corporation are pecuniarily or otherwise interested in,
or are directors or officers of such other corporation; any Director
individually, or any firm of which such director may be a member, may be a
party to, or may be pecuniarily or otherwise interested in, any contract or
transaction of this Corporation; provided, however, that the fact that he or
such firm is so interested shall be disclosed or shall have been made known to
the Board of Directors, or a majority thereof, and any Director of this
Corporation who is also a director or officer of such other corporation, or who
is so interested, may be counted in determining the existence of a quorum at
any meeting of the Board of Directors of the Corporation which shall authorize
such contract or transaction and may vote at such meeting to authorize such
contract or transaction with like force and effect as if he were not such
director or officer of such other corporation or not so interested.

         9.3  Indemnification.  This corporation shall indemnify and all
persons who may serve or who have served at any time as Directors or officers
and their respective heirs, administrators, successors and assigns, against any
and all expenses, including amounts paid upon judgments, counsel fees and
amounts paid in settlement (before or after suit is commenced), actually and
necessarily incurred by such persons in connection with the defense or
settlement of any claim, action, suit or proceeding in which they, or any of
them, are made parties, or a party, or which may be asserted against them or
any of them, by reason of being or having been Directors or officers or a
Director or an officer of the Corporation, except in relation to matters as to
which any such Director or officer or former Director or officer or person
shall be adjudged in any action, suit or proceeding to be liable for his
fraud, gross negligence or gross misconduct involving the Corporation in the
performance of his duties.  Such indemnification shall be in addition to any
other rights to which those indemnified may be entitled under any law, by-law,
agreement, vote of shareholders or otherwise.

         9.4  No Right to Dissent.  No right to dissent shall exist in behalf
of any shareholder as to any corporate action if such action shall be approved
by the vote or written consent of the holders of at least ninety percent (90%)
of all outstanding shares of the corporation, nor shall any such right to
dissent exist in behalf of the holders of the shares of any class or classes of
stock if such corporate action be approved by the vote or written consent of
the holders of at least ninety percent (90%) of all outstanding shares and of
at least three-fourths (3/4) of the shares of such class or classes.

laws of the State of Oklahoma, the Board of Directors of this Corporation is
expressly authorized.

         10.1    Encumbrances.  To authorize and cause its officers to execute
mortgages and liens upon, and grant security interests in, the property, both
real and personal, and upon the franchises of this Corporation; and

         10.2  Committees.  To designate, by resolution passed by a majority of
the whole Board of Directors, one or more committees, each to consist of one or
more Directors, which committees, to the extent provided in such resolution or
in the By-laws of this Corporation, shall have and may exercise any or all of
the powers of the Board of Directors in the management of the business and
affairs of this Corporation and shall have power to authorize the seal of this
Corporation to be affixed by its officers to all papers which may require it.
A majority of the stock issued and outstanding of this Corporation having
voting power may in the By-laws confer power additional to the foregoing upon
the Directors in addition to the powers and authorities expressly conferred
upon them by law.

<PAGE>   25
investigative (other than an action by or in the right of the corporation) by
reason of the fact that he is or was a director, officer, employee or agent of
the corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, against expenses (including attorneys
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by him in connection with such action, suit or proceeding if he acted
in good faith and in a manner he reasonably believed to be in or not opposed to
the best interest of the corporation, and, with respect to any criminal action
or proceeding, had no reasonable cause to believe his conduct was unlawful.

                 SECTION 2.  The corporation shall indemnify any person who was
or is a party or is threatened to be made a party to any threatened, pending or

despite the adjudication of liability but in view of all circumstances of the
case, such person is fairly and reasonably entitled to indemnity for such
expenses which such court shall deem proper.

                 SECTION 3.  The termination of any action, suit or proceeding
by judgment, order, settlement, conviction, or upon a plea of nolo contendere
or its equivalent, shall not, of itself, create a presumption that the person
did not act in good faith and in a manner which he reasonably believed to be in

any criminal action or proceeding, had reasonable cause to believe that his
conduct was unlawful.

to be indemnified by the corporation as authorized in this section.

the substantive standards established hereunder.  Such determination shall be
made (1) by the Board of Directors by a majority vote of a quorum consisting of
directors who were not parties to such action, suit or proceeding, or (2) if
such a quorum is not obtainable, or, even if obtainable a quorum of
disinterested directors so directs, by independent legal counsel in a written
opinion, or (3) by the shareholders.  The indemnification hereunder shall
continue as to a person who has ceased to be a director, officer, employee or
agent and shall inure to the benefit of the heirs or personal representative of
such person.

                 SECTION 6.  The corporation shall have power to purchase and
maintain insurance on behalf of any person who is or was a director, officer,
employee or agent of the corporation, or is or was serving at the request of
the corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise, against any
liability asserted against him and incurred by him in any such capacity or
arising out of his status as such, whether or not the corporation would have
the power to indemnify him against such liability under the provisions of this
section.

preside at all meetings of the shareholders.

the best interests of the corporation, and, with respect to any criminal action
or proceeding, had reasonable cause to believe that his conduct was unlawful.

         Section 2.  The corporation shall indemnify any person who was or is a
party or is threatened to be made a party to any threatened, pending or
completed action or suit by or in the right of the corporation to procure a
judgment in its favor by reason of the fact that he is or was a director,
officer, employee or agent of the corporation, or is or was serving at the
request of the corporation as a director, officer, employee or agent of the
corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise,





                                       19
<PAGE>   20
against expenses (including attorneys' fees) actually and reasonably incurred
by him in connection with the defense or settlement of such action or suit if
he acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interests of the corporation; provided, however, that no
indemnification shall be made in respect to any claim, issue or matter as to
which such person shall have been adjudged to be liable to the corporation
except to the extent that the court in which such action or suit was brought
shall determine upon application that, despite the adjudication of liability
but in view of all circumstances of the case, such person is fairly and
reasonably entitled to indemnity for such expenses which such court shall deem
proper.

         Section 3. To the extent that a director, officer, employee or agent
of the corporation has been successful on the merits or otherwise in defense of
any action, suit or proceeding referred to in Sections 1 and 2, or in defense
of any claim, issue or matter therein, he shall be indemnified against expenses
(including attorneys' fees) actually and reasonably incurred by him in
connection therewith.

         Section 4.  Any indemnification under Sections 1 and 2 (unless ordered
by a court) shall be made by the corporation only as authorized in the specific
case upon a determination that indemnification of the director, officer,
employee or agent is proper in the circumstances because he has met the
applicable standard of conduct set forth in Sections 1 and 2. Such
determination shall be made (a) by the Board of Directors by a majority vote of
a quorum consisting of directors who were not parties to such action, suit or
proceeding, or (b) if such a quorum is not obtainable, or, even if obtainable a
quorum of disinterested directors so directs, by independent legal counsel in a
written opinion, or (c) by the stockholders.

         Section 5.  Expenses incurred by an officer or director in defending a
civil or criminal action, suit or proceeding may be paid by the corporation in
advance of the final disposition of such action, suit or proceeding upon
receipt of an undertaking by or on behalf of such director or





                                       20
<PAGE>   21
officer to repay such amount if it shall ultimately be determined that he is
not entitled to be indemnified by the corporation as authorized in this
Article.  Such expenses incurred by other employees and agents may be so paid
upon such terms and conditions, if, any, as the Board of Directors deems
appropriate.

         Section 6.  The indemnification and advancement of expenses provided
by or granted pursuant to, the other Sections of this Article shall not be
deemed exclusive of any other rights to which those seeking indemnification or
advancement of expenses may be entitled under any agreement, vote of
stockholders or disinterested directors or otherwise, both as to action in his
official capacity and as to action in another capacity while holding such
office.

         Section 7. The indemnification and advancement of expenses provided
by, or granted pursuant to, this Article shall, unless otherwise provided when
authorized or ratified, continue as to a person who has ceased to be a
director, officer, employee or agent and shall inure to the benefit of the
heirs, executors and administrators of such a person.

         Section 8.  The corporation shall have power to purchase and maintain
insurance on behalf of any person who is or was a director, officer, employee
or agent of the corporation, or is or was serving at the request of the
corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise against any liability
asserted against him and incurred by him in any such capacity, or arising out
of his status as such, whether or not the corporation would have the power to
indemnify him against such liability under the provisions of this Article.

         Section 9.  For purposes of this Article, references to "the
corporation" shall include, in addition to the resulting corporation, any
constituent corporation (including any constituent of a constituent) absorbed
in a consolidation or merger which, if its separate existence had continued,
would have had power and authority to indemnify its directors, officers, and
employees or agents,





                                       21
<PAGE>   22
so that any person who is or was a director, officer, employee or agent of such
constituent corporation, or is or was serving at the request of such
constituent corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise, shall stand
in the same position under the provisions of this Article with respect to the
resulting or surviving corporation as he would have with respect to such
constituent corporation if its separate existence had continued.

         Section 10.  For purposes of this Article, references to "other
enterprises" shall include employee benefit plans; references to "fines" shall
include any excise taxes assessed on a person with respect to an employee
benefit plan; and references to "serving at the request of the corporation"
shall include any service as a director, officer, employee or agent of the
corporation which imposes duties on, or involves services by, such director,
officer, employee, or agent with respect to an employee benefit plan, its
participants, or beneficiaries; and a person who acted in good faith and in a
manner he reasonably believed to be in the interest o@f the participants and
beneficiaries of an employee benefit plan shall be deemed to have acted in a
manner "not opposed to the best interests of the corporation' as referred to in
this Article.

estimated expense of litigating the action to conclusion) actually and
reasonably incurred in connection with the defense or settlement of such action
and no indemnification shall be made in respect of any claim, issue or matter
as to which such person shall have been adjudged to be liable for negligence or
misconduct in the performance of his duty to the corporation unless and only to
the extent that the court shall determine upon application that, despite the
adjudication of liability but in view of all the circumstances of the case, he
is fairly and reasonably entitled to indemnity for such expenses which the
court shall deem proper. The termination of any action, suit or proceeding by
judgment, order, settlement, conviction, or upon a plea of nolo contendere or
its equivalent, shall not, of itself, create a presumption that the person did
not act in good faith and in a manner which he reasonably believed to be in or
not opposed to the best interests of the corporation, and, with respect to any
criminal action or proceeding, had reasonable cause to believe that his conduct
was unlawful.

       Section 2. To the extent that a director, officer, employee or agent of
the corporation has been successful on the



                                      -24-
<PAGE>   25
the merits or otherwise in defense of any such action, suit or proceeding, or
in defense of any claim, issue or matter therein, he shall be indemnified
against expenses (including attorneys' fees) actually and reasonably incurred
by him in connection therewith.

       Section 3. The indemnification hereunder (unless ordered by the court)
shall be made by the corporation only as authorized in a specific case upon a
determination that the applicable standard of conduct has been met. Such
determination shall be made (1) by the Board of Directors by a majority vote of
a quorum consisting of directors who were not parties to such action, suit or
proceeding or (2) if such a quorum is not obtainable or a quorum of
disinterested directors so directs, by independent legal counsel, or (3) by the
shareholders.

       Section 4. The expenses incurred in defending such an action, suit or
proceeding shall be paid by the corporation in advance of the final disposition
thereof if authorized by the Board of Directors in the manner provided in
Section 3 above, upon receipt of an undertaking by or on behalf of the
director, officer, employee or agent to repay such amount unless it shall
ultimately be determined that he is entitled to be indemnified by the
corporation as authorized hereunder.

       Section 5. The indemnification provided hereunder shall not be deemed
exclusive of any other rights to which one indemnified may be entitled, both as
to action in his official capacity and as to action in another capacity while
holding such office, and shall continue as to a person who has ceased to be a
director, officer, employee or agent and shall inure to the benefit of his
heirs and legal representatives.

       Section 6. The corporation may procure insurance on behalf of any person
who is or was a director, officer, employee or agent of the corporation, or
is or was serving at the request of the corporation as a director, officer,
employee or agent of another business, nonprofit or foreign corporation,
partnership, joint venture or other enterprise against any liability asserted
against or incurred by him in any such capacity, or arising out of his status as
such, whether or not the corporation would have the power to indemnify him
against such liability under the Business Corporation Law of Louisiana.

                                   BY-LAWS OF
                            SEA MAR MANAGEMENT, INC.

                              SECTION 1.  OFFICES

              1.1  The principal office shall be located at 115 Row 3,
         Lafayette, State of Louisiana 70508.

              1.2  The corporation may have such offices at such other places as
         the Board of Directors may from time to time determine or the business
         of the corporation may require.

                       SECTION 2.  SHAREHOLDERS' MEETINGS

              2.1  All meetings of the shareholders shall be held at the
         principal office of the corporation or at such other place, within or
         without the State of Louisiana, as may be designated by the Board of
         Directors.

              2.2  An annual meeting of the shareholders shall be held on the
         1st day of October in each year, or if said day be legal holiday,
         then on the next succeeding day not a legal holiday, at 10:00 o'clock
         a.m., for the purpose of electing directors and for the transaction of
         such other business as may properly be brought before the meeting;
         provided, however, that the Board of Directors may postpone the annual
         meeting for a period not exceeding 2 months.

              2.3  Special meetings of the shareholders, for any purpose or
         purposes, may be called by the President or Board of Directors.  At
         any time, upon the written request of any two directors or of all the
         directors or of any shareholder or shareholders holding in the
         aggregate one-fifth of the total voting power, the Secretary shall
         call a special meeting of shareholders to be held at the registered
         office of the corporation at such time as the Secretary may fix, not
         less than fifteen nor more than sixty days after the receipt of said
         request.

              2.4  Except as otherwise provided in Section 2.3 hereof, or by
         law, the authorized person or persons calling a shareholders' meeting
         shall cause written notice of the time, place, and purpose of the
         meeting to be given to all shareholders entitled to vote at such
         meeting, at least ten days and not more than sixty days prior to the
         day fixed for the meeting.  Notice of the annual meeting need not
         state the purpose thereof, unless action is to be taken at the meeting
         as to which notice is required by law.    
<PAGE>   2
     2.5 At every meeting of shareholders, a list of shareholders entitled to
vote, arranged alphabetically and certified by the Secretary or by the agent of
the corporation having charge of transfers of shares, showing the number of
shares held by each such shareholder on the record date for the meeting, shall
be produced on the request of any shareholder.

     2.6 Except as otherwise provided by law, the presence, in person or by
proxy, of the holders of a majority of the total voting power shall be
requisite and shall constitute a quorum at all meetings of the shareholders.

     2.7 When a quorum is present at any meeting, the vote of the holders of a
majority of the stock present in person or represented by proxy shall decide
any question brought before such meeting, unless the question is one upon
which, by express provision of law or the Articles of Incorporation, a
different vote is required, in which case such express provision shall govern
and control the decision of such question.

     2.8 At any meeting of the shareholders, every shareholder having the right
to vote shall be entitled to vote in person, or by proxy appointed by an
instrument in writing subscribed by such shareholder and bearing a date not
more than eleven months prior to said meeting, unless said instrument provides
for a longer period. The aforesaid proxy need not be a shareholder of the
corporation. Each shareholder shall have one vote for each share of stock
registered in his name on the books of the corporation at the time of the said
meeting or on the record date for the determination of shareholders entitled to
vote at the said meeting if the Board of Directors shall have fixed such a
record date.

     2.9 Adjournments of any annual or special meeting of shareholders may be
taken without new notice being given unless a new record date is fixed for the
adjourned meeting, but any meeting at which directors are to be elected shall
be adjourned only from day to day until such directors shall have been elected.

     2.10 If a meeting cannot be organized because a quorum has not attended,
those present may adjourn the meeting to such time and place as they may
determine, subject, however, to the provisions of Section 2.9 hereof. In the
case of any meeting called for the election of directors, those who attend the
second of such adjourned meetings, although less than a quorum as fixed in
Section 2.6 hereof, shall nevertheless constitute a quorum for the purpose of
electing directors.

                              SECTION 3. DIRECTORS


     3.1  The business and affairs of the corporation shall be managed by a
Board of Directors. The first Board of Directors shall consist of one (1)
natural person. The number of directors can be increased or decreased within
the limits set forth in the Articles of Incorporation by vote of a majority of
the shareholders present and voting in person or by proxy; provided, however,
that no change in the number of directors under this provision shall have the
effect of shortening the term of any incumbent director. The Board may exercise
all such powers of the corporation and do all such lawful acts and things which
are not by law or by the Articles of Incorporation or by these by-laws directed
or required to be done by the shareholders. The directors shall be elected at
the annual meeting of the shareholders and shall hold office for one year or
until their successors are chosen and have qualified. No director need be a
shareholder.

     3.2  The remaining directors, even though not constituting a quorum, may,
by majority vote, fill any vacancy on the Board (including any vacancy
resulting from an increase in the authorized number in directors, or from
failure of the shareholders to elect the full number of authorized directors)
for an unexpired term, provided that the shareholders shall have the right, at
any special meeting called for the purpose prior to such action by the Board,
to fill the vacancy.

     3.3  Directors, as such, shall receive such salary for their services as
may be fixed by resolution of the Board of Directors and shall receive their
actual expenses of attendance, if any, for each regular or special meeting of
the Board, provided that nothing herein contained shall be construed to preclude
any director from serving the corporation in any other capacity and receiving
compensation therefor.

                        SECTION 4. MEETINGS OF THE BOARD

     4.1  The meetings of the Board of Directors may be held at such place
within or without the State of Louisiana as the directors may from time to time
appoint.

     4.2  The first meeting of each newly elected Board shall be held
immediately following the annual shareholders' meeting and at the same place as
the annual meeting, and no notice of such first meeting shall be necessary to
the newly elected directors in order legally to constitute the meeting.


                                      -3-
<PAGE>   4

     4.3  Regular meetings of the Board may be held without notice at such
time and place either within or without the State of Louisiana as shall from
time to time be determined by the Board.

     4.4  Special meetings of the Board may be called by the President on two
days' notice given to each director, either personally or by telephone, mail, or
telegram. Special meetings shall be called by the President or Secretary in like
manner and on like notice on the written request of two directors and if the
President and Secretary fail or refuse, or are unable to call a meeting when
requested by any two directors, then the two directors may call the meeting on
two days' written notice given to each director.

     4.5  A majority of the Board shall be necessary to constitute a quorum for
the transaction of business, and except as otherwise provided by law, the acts
of a majority of the directors present at a meeting at which a quorum is
present shall be the acts of the Board.

     4.6  If a quorum is present when the meeting is convened, the directors
present may continue to do business taking action by vote of a majority of a
quorum as fixed in Section 4.5 hereof, until adjournment, notwithstanding the
withdrawal of enough directors to leave less than a quorum as fixed in Section
4.5 hereof, or the refusal of any director present to vote.

     4.7  The Board may designate one or more committees, each committee to
consist of one or more directors of the corporation (and one or more directors
may be named as alternate members to replace any absent or disqualified regular
members), which, to the extent provided by resolution of the Board or the
by-laws, shall have and may exercise the powers of the Board in the management
of the business and affairs of the corporation, and may have power to authorize
the seal of the corporation to be affixed to documents. Such committee or
committees shall have such name or names as may be stated in the by-laws, or as
may be determined by the Board. Any vacancy occurring in any such committee
shall be filled by the Board, but the President may designate another Director
to serve on the committee pending action by the Board.  Each such committee
shall hold office during the term of the Board constituting it, unless
otherwise ordered by the Board.

     4.8  Any action which may be taken at a meeting of the Board, or any
committee thereof, may be taken by a consent in writing signed by all of the
directors, or by all members of the committee, as the case may be, and filed
with the records of proceedings of the Board.

<PAGE>   5
     4.9  Meetings of the Board of Directors may further be held by means of
telephone conference calls or similar communications equipment, provided that
all persons participating in such a meeting can hear and communicate with each
other. Participation in a meeting pursuant to this paragraph shall constitute
presence in person at such meeting, except where a person participates in the
meeting for the express purpose of objecting to the transaction of any business
on the ground that the meeting is not lawfully called or convened.

                               SECTION 5. NOTICES

     5.1  Any written notice required or permitted by law, the Articles of
Incorporation or the by-laws to be given to any shareholder or director shall
be deemed to have been given to such shareholder or director (i) when such
notice is served upon such shareholder or director or (ii) two business days
after such notice is placed in the United States mail, postage prepaid,
addressed to such shareholder or director at his last known address.

     5.2  Whenever any notice is required to be given by law or the Articles of
Incorporation, or the by-laws, a waiver thereof in writing signed by the person
or persons entitled to said notice, whether before or after the time stated

He shall preside at all meetings of the shareholders, shall have general and
active management of the business of the corporation, shall have the authority

powers of the President, and shall perform such other duties as the President

the same to any instrument requiring it and, when so affixed, it shall be

     6.8 The Treasurer shall have the custody of the corporate funds and
securities and shall keep full and accurate accounts of receipts and
disbursements in books belonging to the corporation and shall deposit all
moneys and other valuable effects in the name and to the credit of the
corporation in such depositories as may be designated by the Board of
Directors. He shall disburse the funds of the corporation as may be ordered by
the Board, taking proper vouchers for such disbursements, and shall render to
the President and directors, at the regular meetings of the Board, or whenever
they may require it, an account of all his transactions as Treasurer and of the
financial condition of the corporation.

                                SECTION 7. STOCK

     7.2  The Board of Directors may direct a new certificate or certificates
to be issued in place of any certificate or certificates theretofore issued by
the corporation alleged to have been lost or destroyed, upon the making of an
affidavit of that fact by the person claiming the certificate of stock to be
lost or destroyed. When authorizing such issue of a new certificate or
certificates, the Board may, in its discretion and as a condition precedent
to the issuance thereof, require the owner of such lost or destroyed
certificate or certificates, or his legal representative, to advertise the same
in such manner as it shall require and/or give the corporation a bond in such
sum as it may direct as indemnity against any claim that may be made against
the corporation with respect to the certificate alleged to have been lost or
destroyed.

     7.3  Upon surrender to the corporation or the transfer agent of the
corporation, of a certificate for shares duly endorsed or accompanied by proper
evidence of succession, assignment, or authority to transfer, it shall be the
duty of the corporation to issue a new certificate to the person entitled
thereto, cancel the old certificate and record the transaction upon its books. 

     7.4  For the purpose of determining shareholders entitled to notice of and
to vote at a meeting, or to receive a dividend, or to receive or exercise
subscription or other rights, or to participate in a reclassification of stock,
or in order to make a determination of shareholders for any other proper
purpose, the Board of Directors may fix in advance a record date for
determination of shareholders for such purpose, such date to be not more than
sixty days and, if fixed for the purpose of determining shareholders entitled
to notice of and to vote at a meeting, not less than ten days, prior to the
date on which the action requiring the determination of shareholders is to be
taken.

     7.5  Except as otherwise provided by law, the corporation, and its
directors, officers and agents, may recognize and treat a person registered on
its records as the owner of shares, as the owner in fact thereof for all
purposes, and as the person exclusively entitled to have and to exercise all
rights and privileges incident to the ownership of such shares, and rights
under this section shall not be affected by any actual or constructive notice
which the corporation, or any of its directors, officers or agents, may have to
the contrary.

     7.6  Except as otherwise provided by law or the Articles of Incorporation,
dividends upon the stock of the corporation may be declared by the Board of
Directors at any regular or special meeting. Dividends may be paid in cash, in
property, or in shares of stock.

<PAGE>   8
              7.7  The Board of Directors may create and abolish reserves out
          of earned  surplus for any proper purposes.  Earned surplus so
          reserved shall not be available for payment of dividends, purchase or
          redemption of shares, or transfer to capital surplus or stated
          capital.

                           SECTION 8.  MISCELLANEOUS

              8.1  All checks or demands for money and notes of the corporation
          shall be signed by such officer or officers or such other person or
          persons as the Board of Directors may from time to time designate.

              8.2  The Board of Directors may adopt for and on behalf of the
          corporation a fiscal or a calendar year.

              8.3  The Board of Directors may adopt a corporate seal, which
          seal shall have inscribed thereon the name of the corporation.  Said
          seal may be used by causing it or a facsimile thereof to be impressed
          or affixed or reproduced or otherwise.  Failure to affix the seal
          shall not, however, affect the validity of any instrument.

                          SECTION 9.  INDEMNIFICATION

              9.1  The corporation shall indemnify any person who was or is a
          party or is threatened to be made a party to any action, suit or
          proceeding, whether civil, criminal, administrative or investigative
          (including any action by or in the right of the corporation) by reason
          of the fact that he is or was a director, officer, employee or agent
          of the corporation, or is or was serving at the request of the
          corporation as a director, officer, employee or agent of another
          business, foreign or nonprofit corporation, partnership, joint      
          venture or other enterprise, against expenses (including
          attorney's fees), judgments, fines and amounts paid in settlement
          actually and reasonably incurred by him in connection with such
          action, suit or proceeding if he acted in good faith and in a manner
          he reasonably believed to be in or not opposed to the best interests
          of the corporation, and, with respect to any criminal action or
          proceeding, had no reasonable cause to believe his conduct was
          unlawful; however, in case of actions by or in the right of the
          corporation, the indemnity shall be limited to expenses including
          attorney's fees and amounts paid in settlement, not exceeding, in the
          judgment of the Board of Directors, the estimated expense of
          litigating the action to conclusion, actually and reasonably incurred
          in connection with the defense or settlement of such action and no
          indemnification

                                      -8-
<PAGE>   9
shall be made in respect of any claim, issue or matter as to which such person
shall have been adjudged by a court of competent jurisdiction, after exhaustion
of all appeals therefrom, to be liable for willful or intentional misconduct in
the performance of his duty to the corporation unless and only to the extent
that the court shall determine upon application that, despite the adjudication
of liability but in view of all the circumstances of other case, he is fairly
and reasonably entitled to indemnity for such expenses which the court shall
deem proper.  The termination of any action, suit or proceeding by judgment,
order, settlement, conviction, or upon a plea of nolo contendere or its
equivalent, shall not, of itself, create a presumption that the person did not
act in good faith and in a manner which he reasonably believed to be in or not
opposed to the best interests of the corporation, and, with respect to any
criminal action or proceeding, had reasonable cause to believe that his conduct
was unlawful.

     9.2  To the extent that a director, officer, employee, or agent of the 
corporation has been successful on the merits or otherwise in defense of any
such action, suit or proceeding, or in defense of any claim, issue or matter
therein, he shall be indemnified against expenses (including attorneys' fees)
actually and reasonably incurred by him in connection therewith.

     9.3  The indemnification hereunder (unless ordered by the court) shall be
made by the corporation only as authorized in a specific case upon a
determination that the applicable standard of conduct has been met.  Such
determination shall be made (1) by the Board of Directors by a majority vote of
a quorum consisting of directors who were not parties to such action, suit or
proceeding, or (2) if such a quorum is not obtainable and the board of
directors so directs, by independent legal counsel, or (3) by the shareholders.

     9.4  The expenses incurred in defending such an action, suit or proceeding
shall be paid by the corporation in advance of the final disposition thereof if
authorized by the Board of Directors, without regard to whether participating
members thereof are parties to such action, suit, or proceeding, upon receipt
of an undertaking by or on behalf of the director, officer, employee or agent
to repay such amount unless it shall ultimately be determined that he is
entitled to be indemnified by the corporation as authorized hereunder.

     9.5  The indemnification and advancement of expenses provided for by or
granted pursuant to these By-Laws shall not be deemed exclusive of any other
rights to which one indemnified or obtaining advancement of expenses may be
entitled, both as to action in his official capacity and as to action in
another capacity while holding such office, and shall continue as to a



                                      -9-
<PAGE>   10
person who has ceased to be a director, officer, employee or agent and shall
inure to the benefit of his heirs and legal representatives; however, no such
other indemnification measure shall permit indemnification of any person, for
the results of such person's willful or intentional misconduct.

     9.6  The corporation may procure insurance on behalf of any person who is
or was a director, officer, employee or agent of the corporation, or is or was
serving at the request of the corporation as a director, officer, employee or
agent of another business, nonprofit or foreign corporation, partnership, joint
venture or other enterprise against any liability asserted against or incurred
by him in any such capacity, or arising out of his status as such, whether or
not the corporation would have the power to indemnify him against such
liability under the Business Corporation Law of Louisiana. The corporation may
create a trust fund or other forms of self insurance arrangement for the benefit
of persons indemnified by the corporation.

                            SECTION 10.  AMENDMENTS

     10.1  These by-laws may be amended or repealed by the Board of Directors
at any regular or special meeting or by the shareholders at any annual or
special meeting, provided notice of the proposed amendment or repeal be
contained in the notice of such annual or special meeting of shareholders.

         Re:  Registration Statement on Form S-4

Ladies and Gentlemen:

                 In connection with the Registration Statement on Form S-4 (the
"Registration Statement") filed by Pool Energy Services Co., a Texas
corporation (the "Company") and Associated Petroleum Services, Inc., Big 10
Fishing Tool Company, Inc., The International Air Drilling Company,
Kuukpik/Pool Arctic Alaska, PCNV, Inc., Pool Alaska, Inc., Pool Americas, Inc.,
Pool-Australia, Inc., Pool California Energy Services, Inc., Pool Company, Pool
Company Houston Ltd., Pool Company Texas, Ltd., Pool International, Inc., Pool
Production Services, Inc., PTX, Inc., Sea Mar, Inc. and Sea Mar Management,
Inc. (collectively, the "Subsidiary Guarantors"), with the Securities and
Exchange Commission (the "SEC") on the date hereof, pursuant to the Securities
Act of 1933, as amended (the "Act"), and the rules and regulations promulgated
thereunder, we have been requested to render our opinion as to the legality of
the securities being registered thereunder.  The Registration Statement relates
to the registration under the Act of the Company's 8-5/8% Senior Subordinated
Notes due 2008, Series B (the "New Notes") and the guarantees of the New Notes
by the Subsidiary Guarantors (the "Note Guarantees").  The New Notes are to be
offered in exchange for the 8-5/8% Senior Notes due 2008, Series A (the "Old
Notes") issued and sold by the Company on March 31, 1998, in an offering exempt
from registration under the Act.  The New Notes will be issued by the Company
pursuant to the terms of the Indenture (the "Indenture"), dated as of March 31,
1998, among the Company, the Subsidiary Guarantors and Marine Midland Bank, as
trustee (the "Trustee").  Capitalized terms used herein and not otherwise
defined herein shall have the respective meanings ascribed thereto in the
Registration Statement.

                 In connection with this opinion, we have examined originals,
conformed copies or photocopies, certified or otherwise identified to our
satisfaction, of the following documents:

         (i)     the Registration Statement (including the exhibits thereto);

         (ii)    the Indenture included as Exhibit 4.1 to the Registration
Statement (including the Note Guarantees set forth therein); and

<PAGE>   2
         (iii)    the form of the New Notes included as Exhibit A to the
Indenture.

                 In addition, we have examined: (i) such corporate records of
the Company and the Subsidiary Guarantors as we have considered appropriate,
including copies of their certificates of incorporation, as amended, and
by-laws, as amended, in each case, or equivalent governing documents, as in
effect on the date hereof, and certified copies of resolutions of the boards of
directors of the Company and the Subsidiary Guarantors; and (ii) such other
certificates, agreements and documents as we deemed relevant and necessary as a
basis for the opinions hereinafter expressed.

                 In our examination of the aforesaid documents, we have
assumed, without independent investigation, the genuineness of all signatures,
the enforceability of the documents against each party thereto other than the
Company and the Subsidiary Guarantors, the authenticity of all documents
submitted to us as originals, the conformity to the original documents of all
documents submitted to us as certified, photostatic, reproduced or conformed
copies of validly existing agreements or other documents, the authenticity of
all such latter documents and the legal capacity of all individuals who have
executed any of the documents which we examined.

                 In expressing the opinions set forth herein, we have assumed
the due authorization, execution and delivery under New York law of the
Indenture and Note Guarantees by the Company and the Subsidiary Guarantors, as
the case may be, and we have relied upon the factual matters contained in the
representations and warranties of the Company and the Subsidiary Guarantors
made in such documents and upon certificates of public officials and officers
of the Company and the Subsidiary Guarantors, and we have assumed that the New
Notes will be issued as described in the Registration Statement.

                 Based on the foregoing, and subject to the assumptions,
exceptions and qualifications set forth herein, we are of the opinion that:

         1.      The Indenture (including the Note Guarantees set forth
therein) represents a valid and binding obligation of the Company and each of
the Subsidiary Guarantors enforceable against the Company and each of the
Subsidiary Guarantors in accordance with its terms, except as such
enforceability may be subject to (a) bankruptcy, insolvency, fraudulent
conveyance or transfer, reorganization, moratorium or other similar laws
affecting creditors' rights generally and (b) general principles of equity
(regardless of whether such enforcement is considered in a proceeding in equity
or at law).

         2.      When issued, authenticated and delivered in accordance with
the terms of the Indenture, the New Notes will be legal, valid and binding
obligations of the Company enforceable against the Company in accordance with
their terms, except as such enforceability may be limited by (a) bankruptcy,
insolvency, fraudulent conveyance or transfer, reorganization, moratorium and
other similar laws affecting creditors' rights generally and (b) general
principles of equity (regardless of whether such enforcement is considered in a
proceeding in equity or at law).

                 Our opinions expressed above are limited to the laws of the
State of New York and the federal laws of the United States.  Our opinions are
rendered only with respect to the laws, and the rules, regulations and orders
thereunder, that are currently in effect.

Ladies and Gentlemen:

         Subject to the terms and conditions of the Exchange Offer, the
undersigned hereby tenders to the Company the principal amount of Old Notes
indicated above.  Subject to and effective upon the acceptance for exchange of
the principal amount of Old Notes tendered in accordance with this Letter of
Transmittal, the undersigned sells, assigns and transfers to, or upon the order
of, the Company all right, title and interest in and to the Old Notes tendered
hereby.  The undersigned hereby irrevocably constitutes and appoints the
Exchange Agent its agent and attorney-in-fact (with full knowledge that the
Exchange Agent also acts as the agent of the Company) with respect to the
tendered Old Notes with full power of substitution to (i) deliver such Old
Notes to the Company or transfer ownership of such Old Notes on the account
books maintained by DTC, in each case, together with all accompanying evidences
of transfer and authenticity to, or upon the order of, the Company, (ii)
present such Old Notes or transfer ownership of such Old Notes on the account
books maintained by DTC, for transfer on the books of the Company and (iii)
receive all benefits and otherwise exercise all rights of beneficial ownership
of such Old Notes, all in accordance with the terms of the Exchange Offer.  The
power of attorney granted in this paragraph shall be deemed irrevocable and
coupled with an interest.

         The undersigned hereby represents and warrants that he or she has full
power and authority to tender, sell, assign and transfer the Old Notes tendered
hereby and that the Company will acquire good and unencumbered title thereto,
free and clear of all liens, restrictions, charges and encumbrances and not
subject to any adverse claim, when the same are acquired by the Company.  The
undersigned hereby acknowledges that this Exchange Offer is being made in
reliance upon an interpretation by the staff of the Securities and Exchange
Commission that any New Notes acquired in exchange for Old Notes tendered
hereby may be offered for sale, resold and otherwise transferred by holders
thereof (other than any such Holder that is an "affiliate" of the Company or
any of its subsidiaries within the meaning of Rule 405 under the Securities Act
of 1933 (the "Securities Act")), without compliance with the registration and
prospectus delivery provisions of the Securities Act, provided that such New
Notes are acquired in the ordinary course of business of the Holder receiving
such New Notes and that neither the Holder nor any such other person has an
arrangement with any person to participate in the distribution of such New
Notes.  The undersigned hereby further represents that (i) the New Notes
acquired pursuant to the Exchange Offer are being obtained in the ordinary
course of such Holder's business, (ii) such Holder has no arrangements with any
person to participate in the distribution (within the meaning of the Securities
Act) of such New Notes and (iii) such Holder is not an "affiliate", as defined
under Rule 405 of the Securities Act of the Company or any of its subsidiaries
or, if such Holder is an affiliate, that such Holder will comply with the
registration and prospectus delivery





                                     - 5 -
<PAGE>   6
requirements of the Securities Act to the extent applicable.  If the
undersigned is not a broker-dealer, the undersigned represents that it is not
engaged in, and does not intend to engage in, a distribution of New Notes.  If
the undersigned is a broker-dealer that will receive New Notes for its own
account in exchange for Old Notes that were acquired as a result of
market-making activities or other trading activities, it acknowledges that it
will deliver a prospectus in connection with any resale of such New Notes;
however, by so acknowledging and by delivering a prospectus, the undersigned
will not be deemed to admit that it is an "underwriter" within the meaning of
the Securities Act.  The undersigned will, upon request, execute and deliver
any additional documents deemed by the Exchange Agent or the Company to be
necessary or desirable to complete the assignment, transfer and purchase of the
Old Notes tendered hereby.

         For purposes of the Exchange Offer, the Company shall be deemed to
have accepted validly tendered Old Notes, when, as and if the Company has given
oral or written notice of acceptance thereof to the Exchange Agent.

         If any tendered Old Notes are not accepted for exchange pursuant to
the Exchange Offer for any reason, any such unaccepted Old Notes will be
returned (except as noted below with respect to tenders through DTC), without
expense, to the undersigned at the address shown below or at a different
address as may be indicated herein under "Special Payment Instructions" as
promptly as practicable after the Expiration Date.

         All authority herein conferred or agreed to be conferred in this
Letter of Transmittal shall survive the death, incapacity or dissolution of the
undersigned, and any obligation of the undersigned hereunder shall be binding
upon the administrators, legal representatives, heirs, personal
representatives, successors and assigns of the undersigned.

         The undersigned understands that tenders of Old Notes pursuant to the
procedures described under the caption "The Exchange Offer--Procedures for
Tendering" in the Prospectus and in the instructions hereto will constitute a
binding  agreement between the undersigned and the Company upon the terms and
subject to the conditions of the Exchange Offer.

         Unless otherwise indicated under "Special Payment Instructions,"
please issue the New Notes issued in exchange for the Old Notes accepted for
exchange and return any Old Notes not tendered or not exchanged in the name(s)
of the undersigned (or, in either such event, in the case of Old Notes tendered
by DTC, by credit to the account at DTC).  Similarly, unless otherwise
indicated under "Special Delivery Instructions," please send the New Notes
issued in exchange for the Old Notes accepted for exchange and any Old Notes
not tendered or not exchanged (and accompanying documents, as appropriate) to
the undersigned at the address shown below the  undersigned's signature(s),
unless, in either event, tender is being made through DTC.  In the event that
both "Special  Payment Instructions" and "Special Delivery Instructions" are
completed, please issue the New Notes issued in exchange for the Old Notes
accepted for exchange and return any Old Notes not tendered or not exchanged in
the name(s) of, and send said New Notes to, the person(s) so indicated.  The
undersigned recognizes that the Company has no obligation pursuant to the
"Special Payment Instructions" and "Special Delivery Instructions" to transfer
any Old Notes from the name of the registered holder(s) thereof if the Company
does not accept for exchange any of the Old Notes so tendered.

         Holders of the Old Notes who wish to tender their Old Notes and (i)
whose Old Notes are not immediately available or (ii) who cannot deliver their
Old Notes, this Letter of Transmittal or any other

                                  INSTRUCTIONS

                    FORMING PART OF THE TERMS AND CONDITIONS
                             OF THE EXCHANGE OFFER

         1.      Delivery of this Letter of Transmittal and Old Notes.  The
tendered Old Notes (or a confirmation of a book-entry transfer into the
Exchange Agent's account at DTC of all Old Notes delivered electronically), as
well as a properly completed and duly executed copy of this Letter of
Transmittal or facsimile hereof and any other documents required by this Letter
of Transmittal, must be received by the Exchange Agent at its address set forth
herein prior to 5:00 p.m., New York City time, on the Expiration Date.  The
method of delivery of the tendered Old Notes, this Letter of Transmittal and
all other required documents to the Exchange  Agent is at the election and risk
of the Holder and, except as otherwise provided below, the delivery will be
deemed made only when actually received by the Exchange Agent.  Instead of
delivery by mail, it is recommended that the Holder use an overnight or hand
delivery service.  In all cases, sufficient time should be allowed to assure
timely delivery.  No Letter of Transmittal or Old Notes should be sent to the
Company.

         Holders who wish to tender their Old Notes and (i) whose Old Notes are
not immediately available, or (ii) who cannot deliver their Old Notes, this
Letter of Transmittal or any other documents required hereby to the Exchange
Agent prior to 5:00 p.m., New York City time, on the Expiration Date, must
tender their Old Notes according to the guaranteed delivery procedures set
forth in the Prospectus.  Pursuant to such procedures: (i) such tender must be
made by or through a member firm of a registered national securities exchange
or of the National Association of Securities Dealers, Inc., or a commercial
bank or trust company having an office or correspondent in the United States or
an "eligible guarantor  institution" (an "Eligible Institution") within the
meaning of Rule 17Ad-15 under the Securities Exchange Act of 1934, as amended;
(ii) prior to the Expiration Date, the Exchange Agent must have received from
the Eligible Institution a properly completed and duly executed Notice of
Guaranteed Delivery (by facsimile transmission, mail or hand delivery) setting
forth the name and address of the Holder of the Old Notes, the certificate
number or numbers of such Old Notes and the principal amount of Old Notes
tendered, stating that the tender is being made thereby and guaranteeing that,
within three business days after the Expiration Date, this Letter of
Transmittal (or facsimile hereof) together with the Old Notes  (or a
confirmation of electronic delivery of book-entry delivery into the Exchange
Agent's account at DTC) and any other required documents will be deposited by
the Eligible Institution with the Exchange Agent; and (iii) such properly
completed and executed Letter of Transmittal (or facsimile  hereof), as well as
all other documents required by this Letter of Transmittal and all tendered Old
Notes in proper  form for transfer (or a confirmation of electronic delivery of
book-entry delivery into the Exchange Agent's account at DTC), must be received
by the Exchange Agent within three business days after the Expiration Date, all
as provided in the Prospectus under the caption "The Exchange Offer --
Guaranteed Delivery Procedures."  Any Holder of Old Notes who wishes to tender
his or her Old Notes pursuant to the guaranteed delivery procedures described
above must ensure that the Exchange Agent receives the Notice of Guaranteed
Delivery prior to 5:00 p.m., New York City time, on the Expiration Date.  Upon
request of the Exchange Agent, a Notice of Guaranteed Delivery will be sent to
Holders who wish to tender their Old Notes according to the guaranteed delivery
procedures set forth above.

         All questions as to the validity, form, eligibility (including time of
receipt) and acceptance of tendered Old Notes and withdrawal of tendered Old
Notes will be determined  by the Company in its sole discretion, which
determination will be final and binding.  The Company reserves the absolute
right





                                     - 12 -
<PAGE>   13
to reject any and all Old Notes not properly tendered or any Old Notes the
Company's acceptance of which would, in the opinion of counsel for the Company,
be unlawful.  The  Company also reserves the right to waive any defects or
irregularities or conditions of tender as to the Exchange Offer and/or
particular Old Notes.  The Company's interpretation of the terms and conditions
of the Exchange Offer (including the instructions in this Letter of
Transmittal) shall be final and binding on all parties.  Unless waived, any
defects or irregularities in connection with tenders of Old Notes must be cured
within such time as the Company shall determine.  Neither the Company, the
Exchange Agent nor any other person shall be under any duty to give
notification of defects or irregularities with respect to tenders of Old Notes,
nor shall any of them incur any liability for failure to give such
notification.  Tenders of Old Notes will not be deemed to have been made until
such defects or irregularities have been cured or waived.  Any Old Notes
received by the Exchange Agent that are not validly tendered and as to which
the defects or irregularities have not been cured or waived will be returned by
the Exchange Agent to the tendering  Holders of Old Notes, unless otherwise
provided in this Letter of Transmittal, as soon as practicable following the
Expiration Date.

         2.      Partial  Tenders.  Tenders of Old Notes will be  accepted only
in denominations of $1,000 and any integral  multiples in excess thereof.  If
less than the entire  principal amount of any Old Notes is tendered, the
tendering Holder should fill in the principal amount tendered in the fourth
column of the box entitled "Description of 8-5/8% Senior Subordinated Notes Due
2008, Series A (Old Notes)" above.  The  entire principal amount of Old Notes
delivered to the Exchange Agent will be deemed to have been tendered unless
otherwise indicated.  If the entire principal amount of all Old Notes is not
tendered, then Old Notes for the principal amount of Old Notes not tendered and
the New Notes issued in exchange for any Old Notes accepted will be sent to the
Holder at his or her registered address, unless a different address is
provided in the appropriate box on this Letter of Transmittal, promptly after
the Old Notes are accepted for exchange.

         3.      Signatures on the Letter of Transmittal; Bond Powers and
Endorsements; Guarantee of Signatures.  If this Letter of Transmittal (or
facsimile hereof) is signed by the record Holder(s) of the Old Notes tendered
hereby, the signature must correspond with the name(s) as written on the face
of the Old Notes without alteration, enlargement or any change whatsoever.

         If this Letter of Transmittal (or facsimile hereof) is signed by the
registered Holder or Holders of Old Notes tendered and the New Notes issued in
exchange therefor are to be issued (or any untendered principal amount of Old
Notes is to be reissued) to the registered Holder, the said Holder need not and
should not endorse any tendered Old Notes, nor provide a separate bond power.

         If this Letter of Transmittal (or facsimile hereof) is signed by a
person other than the registered Holder or Holders of any Old Notes listed,
such Old Notes must be endorsed or accompanied by appropriate bond powers
signed as the name of the registered Holder or Holders appears on the Old
Notes.

         If this Letter of Transmittal (or facsimile hereof) or any Old Notes
or bond powers are signed by trustees, executors, administrators, guardians,
attorneys-in-fact or officers of corporations or others acting in a fiduciary
or representative capacity, such persons should so indicate when  signing, and,
unless waived by the Company, evidence satisfactory to the Company of their
authority so to act must be submitted with this Letter of Transmittal.





                                     - 13 -
<PAGE>   14
         Endorsements on Old Notes or signatures on bond powers required by
this Instruction 3 must be guaranteed by an Eligible Institution participating
in a recognized medallion signature guarantee program.

         Except as otherwise provided below, all signatures on this Letter of
Transmittal (or facsimile hereof) must be guaranteed by an Eligible Institution
participating in a recognized medallion signature guarantee program.
Signatures on this Letter of Transmittal need not be guaranteed if (i) this
Letter of Transmittal is signed by the registered Holder(s) of the Old Notes
tendered herewith (including any  participant in DTC whose name appears on a
security position  listing as the owner of Old Notes) and such Holder(s) have
not completed the box set forth herein entitled "Special Payments Instructions"
or the box entitled "Special Delivery Instructions" or (ii) such Old Notes are
tendered for the account of an Eligible Institution.

         4.      Special Issuance and Delivery Instructions.  Tendering Holders
should indicate, in the applicable box or boxes, the name and address to which
New Notes or substitute Old Notes for principal amounts not tendered or not
accepted for exchange are to be issued or sent, if different from the name and
address of the person signing this Letter of Transmittal (or in the case of
tender of the Old Notes  through DTC, if different from DTC).  In the case of
issuance in a different name, the taxpayer identification or social security
number of the person named must also be indicated.

         5.      Tax Identification Number.  Federal income tax law requires
that a Holder whose offered Old Notes are accepted  for exchange must provide
the Company (as payor) with his, her or its correct Taxpayer Identification
Number ("TIN"), which, in the case of an exchanging Holder who is an
individual, is his or her social security  number.  If the Company is not
provided with the correct TIN or an adequate basis for  exemption, such Holder
may be subject to a $50 penalty  imposed by the Internal Revenue Service (the
"IRS").  In addition, delivery to such Holder of New Notes may be subject to
backup withholding in an amount equal to 31% of the gross proceeds resulting
from the Exchange Offer.  If withholding results in an overpayment of taxes, a
refund may be obtained. Exempt Holders  (including, among others, all
corporations  and certain foreign individuals) are not subject to these backup
withholding and reporting requirements.

         To prevent backup withholding, each exchanging Holder  must provide
his, her or its correct TIN by completing the Substitute Form W-9 enclosed
herewith, certifying that the TIN  provided is correct (or that such Holder is
awaiting a TIN) and that either (i) the Holder is exempt from backup
withholding, (ii) the Holder has not been notified by the IRS that he, she or
it is subject to backup withholding as a result of a failure to report all
interest or dividends, or (iii) the IRS has notified the Holder that he, she or
it is no longer subject to backup withholding.  In order to satisfy  the
Exchange Agent that a foreign individual qualifies as an exempt recipient, such
Holder must submit a statement signed under penalty of perjury attesting to
such exempt status.  Such statements may be obtained from the Exchange  Agent.
If the Old Notes are in more than one name or are not in the name of the actual
owner, consult the Substitute Form W-9 for information on which TIN to report.
If you do not provide  your TIN to the Company  within 60 days, backup
withholding  will begin and continue until you furnish your TIN to the Company.

         6.      Transfer Taxes.  The Company will pay all transfer  taxes, if
any, applicable to the exchange of Old Notes  pursuant to the Exchange Offer.
If, however, New Notes or Old Notes for principal amounts not tendered or
accepted for exchange are to be delivered to, or are to be registered or issued
