     The Outstanding Notes were sold by the Company on February 13, 1998 to the
Initial Purchaser (as defined herein) in transactions not registered under the
Securities Act in reliance upon the exemption provided in Section 4(2) of the
Securities Act. The Initial Purchaser subsequently placed the Outstanding Notes
with qualified institutional buyers in reliance upon Rule 144A under the
Securities Act. Accordingly, the Outstanding Notes may not be reoffered, resold
or otherwise transferred in the United States unless so registered or unless an
applicable exemption from the registration requirements of the Securities Act is
available. The Exchange Notes are being offered hereunder in order to satisfy
the obligations of the Company under the Registration Rights Agreement. See "The
Exchange Offer".
 
     Based on an interpretation by the staff of the Securities and Exchange
Commission (the "Commission") set forth in no-action letters issued to third
parties, the Company believes that Exchange Notes issued pursuant to this
Exchange Offer may be offered for resale, resold and otherwise transferred by a
holder who is not an affiliate of the Company without compliance with the
registration and prospectus delivery provisions of the Securities Act, provided
that the holder is acquiring the Exchange Notes in its ordinary course of
business and is not participating in and has no arrangement or understanding
with any person to participate in the distribution (within the meaning of the
Securities Act) of the Exchange Notes. Persons wishing to exchange Outstanding
Notes in the Exchange Offer must represent to the Company that such conditions
have been met.
 
     Each broker-dealer that receives Exchange Notes for its own account
pursuant to the Exchange Offer (a "Participating Broker-Dealer") must
acknowledge that it will deliver a prospectus in connection with any resale of
Exchange Notes. A broker-dealer that delivers such a prospectus to purchasers in
connection with such resales will be subject to certain of the civil liability
provisions under the Securities Act and will be bound by the provisions of the
Registration Rights Agreement (including certain indemnification rights and
obligations). 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 Exchange
Notes received in exchange for Outstanding Notes where such Outstanding Notes
were acquired by such broker-dealer as a result of market-making activities or
other trading activities. The Company has agreed that, if requested by a
Participating Broker-Dealer, it will use its best efforts to make this
Prospectus available to any Participating Broker-Dealer for use in connection
with any such resale for a period of up to one year or such earlier date as such
Participating Broker-Dealer shall have notified the Company in writing that such
Participating Broker-Dealer has resold all Exchange Notes acquired in the
Exchange Offer. See "Plan of Distribution".

     The Company does not intend to list the Exchange Notes on any national
securities exchange or to seek the admission thereof to trading in the National
Association of Securities Dealers Automated Quotation System. The Initial
Purchaser has advised the Company that they intend to make a market in the
Exchange Notes; however, they are not obligated to do so and any market-making
may be discontinued at any time without notice. Accordingly, no assurance can be
given that an active public or other market will develop for the Exchange Notes
or as to the liquidity of or the trading market for the Exchange Notes.
 
     Any Outstanding Notes not tendered and accepted in the Exchange Offer will
remain outstanding. To the extent that any Outstanding Notes are tendered and
accepted in the Exchange Offer, a holder's ability to sell untendered
Outstanding Notes could be adversely affected. Following consummation of the
Exchange Offer, the holders of Outstanding Notes will continue to be subject to
the existing restrictions upon transfer thereof.
 
     The Company expects that the Exchange Notes issued pursuant to this
Exchange Offer will be issued in the form of a Global Exchange Notes (as defined
herein), which will be deposited with, or on behalf of, The Depository Trust
Company (the "Depositary") and registered in its name or in the name of Cede &
Co., its nominee. Beneficial interests in the Global Exchange Notes representing
the Exchange Notes will be shown on, and transfers thereof to qualified
institutional buyers will be effected through, records maintained by the
Depositary and its participants. After the initial issuance of the Global
Exchange Notes, Exchange Notes in certificated form will be issued in exchange
for the Global Exchange Notes on the terms set forth in the Indenture. See
"Description of Exchange Notes -- Book Entry; Delivery and Form".

                                  THE COMPANY
 
     The Company is an integrated provider of specialty services and
technologically-advanced downhole tools to the oil and gas industry on a
worldwide basis. The Company's services include (i) directional drilling
services, (ii) underbalanced drilling services, (iii) electric wireline and
tubing conveyed perforating services, (iv) tubular testing and handling services
and (v) downhole tool rental. The Company has recently expanded its operations
significantly through strategic acquisitions and internal growth. In March 1998,
the Company acquired Integrated Drilling Systems Limited ("IDS"), a specialized
provider of directional drilling services, and in January 1998, the Company
acquired the operating assets and liabilities of DWS/DAMCO, specialized
providers of electric wireline and tubular services in the U.S. Gulf of Mexico
region and, to a lesser extent, in Nigeria. The Company believes the DWS/DAMCO
Acquisition provides it with significant operational benefits, including
geographic expansion and cross-marketing opportunities.
 
OPERATIONS
 
     Directional Drilling Services. Directional drilling services involve
assisting oil and gas operators in the controlled drilling of a wellbore to a
prescribed bottomhole location. Directional drilling can be used to develop a
field with multiple wells drilled from the same offshore platform or, in
environmentally sensitive areas, from fewer surface facilities than conventional
drilling would require. In addition, drilling horizontally through a formation
characterized by multiple vertical fractures can result in substantial
reductions in drilling costs and improved well productivity because fewer wells
are required compared to a vertical development program. Based on published
industry sources, the number of oil and gas wells drilled in the United States
using directional and horizontal technology increased 120% from 2,110 in 1990 to
4,649 in 1997, and, as a percentage of total oil and gas wells drilled in the
United States, wells drilled using directional and horizontal technology
increased from 7% in 1990 to 17% in 1997. This growth has been driven primarily
by the substantial cost savings, improvements to drilling efficiency and
enhancements to reservoir production that such techniques can provide to
operators as well as increased offshore drilling activity.
 
     The Company provides skilled personnel to manage the drilling of
directional wells. The directional drilling services offered by the Company
consist of well planning, on-site supervisory services to maximize drilling
efficiency, measurement-while-drilling ("MWD") services and related equipment
rentals, downhole motor rentals and post-well analysis. The Company also derives
revenue from its directional drilling services by renting MWD units, thrusters,
downhole motors and nonmagnetic stabilizers. Through the acquisition of IDS, the
Company acquired key technologies, including a resistivity tool for
logging-while-drilling ("LWD") that is compatible with Dailey's MWD equipment.
The Company believes that the addition of LWD technology to Dailey's MWD fleet
will enable it to offer more fully integrated directional drilling systems in
the Gulf of Mexico and Venezuela and will allow the Company to expand the
geographic markets in which it provides
 
                                        1
<PAGE>   6
 
such services. Directional drilling services accounted for approximately $19.3
million, or 26%, of the Company's pro forma revenue for the six months ended
October 31, 1997.
 
     Underbalanced Drilling Services. Underbalanced drilling involves
maintaining the pressure in a well at less than that of the surrounding
formation using air, nitrogen, mist, foam or lightweight drilling fluids as the
circulation medium instead of mud. As a result of the ADI Acquisition, the
Company is a worldwide leader in providing air drilling services, which are used
in underbalanced drilling applications, and, since the acquisition, the Company
has leveraged off these services to develop internally the ability to provide
other services utilized in underbalanced drilling applications. The Company
provides underbalanced drilling equipment packages consisting of compressors,
boosters, mist pumps and related equipment along with specially-trained
personnel to operate the equipment. Underbalanced drilling techniques can lead
to substantial increases in rates of penetration and drill bit life resulting in
substantially less time and cost for a drilling program and can reduce
substantially the risks of formation damage. Underbalanced drilling services
accounted for approximately $15.9 million, or 21%, of the Company's pro forma
revenue for the six months ended October 31, 1997.
 
     Electric Wireline and Tubing Conveyed Perforating Services. As a result of
the DWS/DAMCO Acquisition, the Company is a leading provider of electric
wireline and tubing conveyed perforating ("TCP") services in the U.S. Gulf of
Mexico region and Nigeria. The Company's electric wireline services are utilized
in both the exploration and production phases of an oil and gas well and include
pipe recovery, cased hole logging, electric wireline perforating services and
other cased hole services such as installation of bridge plugs, packers,
retainers, pressure control equipment and thru-tubing bridge plugs.
 
     TCP services involve the use of tubing string to lower and retrieve
perforating charges from the wellbore. The Company believes operating synergies
exist between its electric wireline and TCP services and its downhole tool
rental business as such products and services can be effectively marketed in a
single package. The Company intends to expand its electric wireline and TCP
services by marketing these services through its established distribution
networks for its other products and services. Electric wireline and TCP services
accounted for approximately $10.1 million, or 14%, of the Company's pro forma
revenue for the six months ended October 31, 1997.
 
     Tubular Testing and Handling Services. As a result of the DWS/DAMCO
Acquisition, the Company is a leading provider of tubular testing and handling
services to the offshore and onshore oil and gas industry in the U.S. Gulf of
Mexico region. The Company's tubular testing services consist of hydrostatic and
gas pressure testing services that detect leaks and flaws in tubulars as they
are run into the wellbore. The Company believes operators prefer to incur
testing charges to avoid incurring costly downtime and the expense of pulling a
defective tubular string.
 
     The Company's tubular handling services include assembling production pipe
and tubing, dual completion strings, premium threaded connections and ultra-high
torque tubulars. The Company believes that mistakes in torquing tubulars can be
costly in terms of downtime and damaged equipment and, therefore, operators rely
on experienced tubular companies for handling services. Tubular testing and
handling services accounted for approximately $5.5 million, or 7%, of the
Company's pro forma revenue for the six months ended October 31, 1997.
 
     Downhole Tools. The Company currently offers an array of
technologically-advanced downhole tools, which it selectively markets in every
major oil and gas exploration and production region in the world. Dailey began
renting downhole tools in 1945 and introduced the first drilling jar to the oil
and gas industry in 1965. The Company is currently the leading supplier of
drilling jars to the rental tool market worldwide. A drilling jar is an impact
tool that is placed in the lower section of a drillstring as part of the
bottomhole assembly and, when activated, delivers a sharp, powerful impact to
free the bottomhole assembly should it become lodged in the hole.
 
     In addition to drilling jars, the Company rents other proprietary downhole
tools including hydraulic fishing jars, coiled tubing jars, drilling shock
absorbers, drilling thrusters and drilling slingers. The Company also derives
revenues from the sale of mechanical drilling jars and from downhole tools that
are lost-in-hole by
 
                                        2
<PAGE>   7
 
the operator. Downhole tool rentals and sales accounted for approximately $22.2
million, or 30%, of the Company's pro forma revenue for the six months ended
October 31, 1997.
 
     Dailey traditionally has marketed its array of proprietary downhole tools
directly to the end-user through its direct sales force and agents, rather than
relying on third-party distribution of its products. The Company believes this
strategy results in higher profit margins, and that this direct interaction with
the end user assists the Company in identifying demand for new and improved
products and better enables it to design and develop such products in a timely
manner.
 
BUSINESS STRATEGY
 
     The Company's strategy is to expand and diversify the geographic
distribution and range of products and services it provides to the drilling,
completion and workover segments of the upstream oil and gas industry through
internal growth and acquisitions. The Company expects to continue to effect
internal growth primarily by cross marketing its product and service lines and
expanding its recently acquired operations to additional locations within the
Company's worldwide infrastructure.
 
     In addition, as consolidation of the oil and gas services industry
continues in response to increased demand for companies offering a broad range
of services, the Company intends to continue expanding its products and services
through strategic acquisitions. The Company continuously evaluates potential
acquisition candidates in the drilling, workover and completion segments of the
oilfield services industry, including companies providing directional drilling,
underbalanced drilling, fishing and enhanced recovery services, as well as
companies supplying specialized downhole tools and other equipment to the oil
and gas industry. The Company is reviewing several acquisition opportunities
that, if consummated, would allow it to continue to expand the breadth and
geographic scope of the products and services it offers as well as create
additional cross-marketing opportunities for internal growth.
 
RECENT DEVELOPMENTS
 
     Consistent with its strategy, since April 1997, Dailey has completed five
acquisitions, all of which expand Dailey's scope of operations and geographic
presence and add long-term earnings capacity.
 
     - Integrated Drilling Services Limited. In March 1998, the Company acquired
       the outstanding capital stock of IDS (the "IDS Acquisition"), a
       directional drilling service company, for $9.4 million in cash and

                             Agreement dated February 6, 1998 (the "Purchase
                             Agreement"). The Initial Purchaser subsequently

                             the Initial Purchaser entered into a Registration

                             "Registration Rights Agreement"), which grants the

                             terminate upon the consummation of the Exchange
                             Offer. If applicable law or applicable
                             interpretations of the staff of the Commission do
                             not permit the Company to effect the Exchange
                             Offer, or in certain other circumstances, the
                             Company has agreed to file a shelf registration
                             (the "Shelf Registration Statement") covering
                             resales of Transfer Restricted Securities (as
                             defined). See "The Exchange Offer -- Resale of
                             Exchange Notes".
 
                               THE EXCHANGE OFFER
 
Securities Offered.........  $275,000,000 aggregate principal amount of 9 1/2%
                             Senior Notes due 2008, Series B.
 
The Exchange Offer.........  $1,000 principal amount of the Exchange Notes in
                             exchange for each $1,000 principal amount of
                             Outstanding Notes. As of the date hereof,
                             $275,000,000 aggregate principal amount of
                             Outstanding Notes are outstanding. The Company will
                             issue the Exchange Notes to holders on or about May
                             14, 1998 (the "Exchange Date").
 
                             Based on an interpretation of the staff of the
                             Commission set forth in no-action letters issued to
                             third parties, the Company believes that Exchange
                             Notes issued pursuant to the Exchange Offer in
                             exchange for Outstanding Notes may be offered for
                             resale, resold and otherwise transferred by any
                             holder 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 provisions of the Securities Act, provided
                             that such Exchange Notes are acquired in the
                             ordinary course of such holder's business and that
                             such holder does not intend to participate and has
                             no arrangement or understanding with any person to
                             participate in the distribution of such Exchange
                             Notes.
 
                             Each Participating Broker-Dealer must acknowledge
                             that it will deliver a prospectus in connection
                             with any resale of Exchange Notes. A broker-dealer
                             that delivers such a prospectus to purchasers in
                             connection with such resales will be subject to
                             certain of the civil liability provisions under the
                             Securities Act and will be bound by the provisions
                             of the Registration Rights Agreement (including
                             certain indemnification rights and obligations).
                             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
                             Exchange Notes received in exchange for Outstanding
                             Notes where such Outstanding Notes were acquired by
                             such broker-dealer as a result of market-making
                             activities or other trading activities. The Company
                             has agreed that, if requested by a Participating
                             Broker-

                             Prospectus available to any Participating
                             Broker-Dealer for use in connection with any such
                             resale for a period of up to one year or such
                             earlier date as such Participating Broker-Dealer
                             shall have notified the Company in writing that
                             such Participating Broker-Dealer has resold all
                             Exchange Notes acquired in the Exchange Offer. See
                             "Plan of Distribution".
 
                             Any holder who tenders in the Exchange Offer with
                             the intention to participate, or for the purpose of
                             participating, in a distribution of the Exchange
                             Notes can not rely on the position of the staff of
                             the Commission enunciated in Exxon Capital Holdings
                             Corporation (available April 13, 1989) or similar

                             of the Securities Act in connection with the resale
                             transaction. Failure to comply with such
                             requirements in such instance may result in such
                             holder incurring liability under the Securities Act
                             for which the holder is not indemnified by the
                             Company.

                             continue to hold the untendered Outstanding Notes
                             and will be entitled to all the rights and subject

                             limitations, by their terms, terminate or cease to
                             have further effectiveness as a result of the
                             Exchange Offer. All untendered Outstanding Notes
                             will continue to be subject to certain restrictions
                             on transfer. Accordingly, if any Outstanding Notes
                             are tendered and accepted in the Exchange Offer,
                             the trading market of the untendered Outstanding
                             Notes could be adversely affected. See "The

                             Indebtedness of the Company. The Exchange Notes and
                             the Subsidiary Guarantees will be effectively
                             subordinated to secured Indebtedness of the Company
                             and the Subsidiary Guarantors, respectively,
                             including any Indebtedness under the Company's
                             Third Amended and Restated Credit Facility dated

                             Facility"), which is secured by liens on
                             substantially all of the assets of the Company and
                             the Subsidiary Guarantors. At October 31, 1997, pro

                             application of the net proceeds therefrom, the
                             Exchange Notes and the Subsidiary Guarantees would
                             have been effectively subordinated to $2.1 million

                             Guarantors. The Indenture permits the Company and

                             of Additional Indebtedness".

                             in right of payment with all Senior Indebtedness of
                             the Subsidiary Guarantors and senior to all
                             subordinated Indebtedness of the Subsidiary
                             Guarantors. The Subsidiary Guarantees may be
                             released under certain circumstances. See

(1) Adjusted in the case of statement of operations data to reflect the
    consummation of the ADI Acquisition, the DWS/DAMCO Acquisition, the issuance
    of the Outstanding Notes and the application of the net proceeds therefrom
    as if each had occurred on May 1, 1996, and, in the case of balance sheet
    data, to reflect the consummation of the DWS/DAMCO Acquisition, the issuance
    of the Outstanding Notes and the application of the net proceeds therefrom
    as if each had occurred on October 31, 1997.
 
(2) Reorganization costs relate primarily to staff reductions, severance
    settlements and various costs associated with a cost reduction program
    implemented in June 1997 to flatten Dailey's management structure and
    streamline its operations.
 
(3) Non-cash compensation expense relates to accelerated vesting of restricted
    stock that was granted to certain executive officers of Dailey during the
    year ended April 30, 1997 and the six months ended October 31, 1997.
 
(4) Pro forma operating results are presented before extraordinary items. As a
    result of the repurchase of all of the Company's 9 3/4% Senior Notes Due
    2007 (the "Old Notes") utilizing a portion of the net proceeds from the
    issuance of the Outstanding Notes, the Company immediately recognized an
    extraordinary loss (nonrecurring charge) of approximately $17,784,000 (or
    $1.91 per share) on the early retirement of the Old Notes with no related
    income tax benefit recognized for financial reporting purposes.
 
(5) Maintenance capital expenditures are primarily comprised of expenditures for
    the replacement of downhole tools lost-in-hole or scrapped and for
    capitalizable repair of assets.
 
(6) Discretionary capital expenditures are primarily comprised of expenditures
    for additions to the downhole equipment, compressors, boosters and other
    property and equipment. All DWS/DAMCO capital expenditures have been
    classified as discretionary.

                                  RISK FACTORS
 
     Holders of the Outstanding Notes should consider carefully the following
factors as well as the other information provided elsewhere in this Prospectus
before deciding to invest in the Exchange Notes. See "Disclosure Regarding
Forward-Looking Statements".
 
CONSEQUENCES OF EXCHANGE AND FAILURE TO EXCHANGE
 
     Holders of Outstanding Notes who do not exchange their Outstanding Notes
for Exchange Notes pursuant to the Exchange Offer will continue to be subject to
the restrictions on transfer to such Outstanding Notes as set forth in the
legend thereon as a consequence of the issuance of the Outstanding Notes
pursuant to exemptions from, or in transactions not subject to, the registration
requirements of the Securities Act and applicable state securities laws. In
general, the Outstanding Notes that are not tendered, or are tendered but not
accepted, 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 Outstanding Notes under the
Securities Act. In addition, upon the consummation of the Exchange Offer holders
of Outstanding Notes that remain outstanding will not be entitled to any rights
to have such Outstanding Notes registered under the Securities Act or to any
similar rights under the Registration Rights Agreement. To the extent that
Outstanding Notes are tendered and accepted in the Exchange Offer, a holder's
ability to sell untendered, or tendered but unaccepted, Outstanding Notes could
be adversely affected. The Registration Rights Agreement provides that if (i)
the Exchange Offer has not been consummated within 30 days of the effectiveness
of the Registration Statement, (ii) a shelf registration statement has not been
declared effective by February 15, 1998, or (iii) this Registration Statement is
filed and declared effective but shall thereafter cease to be effective and is
not immediately followed by an additional Registration Statement that is filed
and declared effective, the interest rate on the Outstanding Notes will increase
by an amount of 0.5% for each 90-day period following such Registration Default,
up to a maximum amount of 2.0% per annum, until such Registration Default is
cured.
 
INCURRENCE OF SUBSTANTIAL INDEBTEDNESS
 
     At October 31, 1997, on a pro forma basis after giving effect to the
DWS/DAMCO Acquisition, the issuance of the Outstanding Notes and the application
of the net proceeds therefrom as set forth herein under "Use of Proceeds," the
Company would have had approximately $277.1 million in total indebtedness,
compared with total actual indebtedness of $115.4 million at such date. The
Company historically has operated at substantially lower levels of debt than
will be outstanding after giving effect to the offering of the Outstanding
Notes. The Company's level of indebtedness will have several important effects
on its future operations, including, without limitation, (i) a substantial
portion of the Company's cash flow from operations must be dedicated to the
payment of interest and principal on its indebtedness, (ii) the Company's
leveraged position will substantially increase its vulnerability to adverse
changes in general economic and industry conditions, as well as to competitive
pressure and (iii) the Company's ability to obtain additional financing for
working capital, capital expenditures, acquisitions, general corporate and other
purposes may be limited. The Company's ability to meet its debt service
obligations and to reduce its total indebtedness will be dependent upon the
Company's future performance, which will be subject to general economic
conditions, industry cycles and financial, business and other factors affecting
the operations of the Company, many of which are beyond its control. There can
be no assurance that the Company's business will continue to generate cash flow
at or above current levels. If the Company is unable to generate sufficient cash
flow from operations in the future to service its debt, it may be required,
among other things, to seek additional financing in the debt or equity markets,
to refinance or restructure all or a portion of its indebtedness, including the
Notes, or to sell selected assets or reduce or delay planned capital
expenditures or acquisitions. There can be no assurance that any such measures
would be sufficient to enable the Company to service its debt or that any such
financing, refinancing or sale of assets would be available on economically
favorable terms.

EFFECTIVE SUBORDINATION
 
     The Exchange Notes will be unsecured and effectively subordinated in right
of payment to all existing and future secured Indebtedness of the Company and
the Subsidiary Guarantors, which will include any future draws under the
Company's Credit Facility. As of October 31, 1997, after giving pro forma effect
to the DWS/DAMCO Acquisition, the issuance of the Outstanding Notes and the
application of the net proceeds therefrom, the Company would have had no Senior
Indebtedness outstanding and would have up to $15.0 million available under the
Credit Facility which, if borrowed, would be included as Senior Indebtedness.
The Credit Facility is secured by liens on substantially all of the assets of
the Company and the Subsidiary Guarantors. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations -- Liquidity and
Capital Resources". Accordingly, lenders under the Credit Facility have claims
with respect to the assets constituting collateral for any indebtedness
thereunder that will be satisfied prior to the unsecured claims of the holders
of the Notes. See "Description of the Notes -- Ranking". In the event of a
default on the Exchange Notes or a bankruptcy, liquidation or reorganization of
the Company, such assets will be available to satisfy obligations with respect
to the indebtedness secured thereby before any payment therefrom could be made
on the Notes. Thus, the Exchange Notes and the Subsidiary Guarantees will be
effectively subordinated to claims of the lenders under the Credit Facility to
the extent of such pledged collateral. At October 31, 1997, pro forma for the
DWS/DAMCO Acquisition, the issuance of the Outstanding Notes and the Exchange
Notes and the application of the net proceeds therefrom, the Exchange Notes and
the Subsidiary Guarantees would have been effectively subordinated to 2.1
million of secured Indebtedness (excluding letters of credit) of the Company or
the Subsidiary Guarantors.
 
     The Exchange Notes are also effectively subordinated to all existing and
future debt and other liabilities of the Company's subsidiaries that do not
guarantee the Exchange Notes. While the Company's subsidiaries do not presently
carry a significant amount of debt, the Indenture permits the existing
subsidiaries to incur additional debt under certain circumstances. In the event
of an insolvency, liquidation or other reorganization of any of the subsidiaries
of the Company, creditors of such subsidiaries, including trade creditors, would
be entitled to payment in full from the assets of such subsidiaries before the
Company, as a stockholder, would be entitled to receive any distribution
therefrom.
 
FRAUDULENT CONVEYANCE
 
     Various fraudulent conveyance laws enacted for the protection of creditors
may apply to the Subsidiary Guarantors' issuance of the Subsidiary Guarantees.
To the extent that a court were to find that (x) a Subsidiary 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 Subsidiary Guarantee and such
Subsidiary Guarantor (i) was insolvent, (ii) was rendered insolvent by reason of
the issuance of such Subsidiary 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 Subsidiary Guarantee in favor of the Subsidiary Guarantor's creditors.
Among other things, a legal challenge of a Subsidiary 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 its Subsidiary 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 Subsidiary Guarantee of any Subsidiary Guarantor was avoided as
a fraudulent conveyance or held unenforceable for any other reason, holders of
the Exchange Notes would cease to have any claim against such Subsidiary
Guarantor and would be creditors solely of the Company and any Subsidiary
Guarantor whose Subsidiary Guarantee was not avoided or held unenforceable. In
such event, the claims of the holders of the Exchange Notes against the issuer
of an invalid Subsidiary Guarantee would be subject to the prior payment
 
                                       12
<PAGE>   17
 
of all liabilities of such Subsidiary Guarantor. There can be no assurance that,
after providing for all prior claims, there would be sufficient assets to
satisfy the claims of the holders of the Exchange Notes relating to any avoided
portions of any of the Subsidiary 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
of 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.
 
     Based upon financial and other information, the Company and the Subsidiary
Guarantors believe that the Guarantees are being incurred for proper purposes
and in good faith and that the Company and each Subsidiary Guarantor is solvent
and will continue to be solvent after issuing its Subsidiary Guarantee, will
have sufficient capital for carrying on its business after such issuance and
will be able to pay its debts as they mature. There can be no assurance,
however, that a court passing on such standards would agree with the Company.
See "Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources" and "Description of the Exchange
Notes -- Subsidiary Guarantees".
 
RESTRICTIONS IMPOSED BY LENDERS
 
     The Credit Facility and the Indenture contain a number of covenants that
restrict the ability of the Company to dispose of assets, merge or consolidate
with another entity, incur additional indebtedness, create liens, make capital
expenditures, pay dividends or make other investments or acquisitions and
covenants that otherwise restrict corporate activities. The Credit Facility also
contains requirements that the Company maintain certain financial ratios and may
restrict the Company from prepaying the Company's other indebtedness. The
ability of the Company to comply with such provisions may be affected by events
that are beyond the Company's control. The breach of any of these covenants
could result in a default under the Credit Facility and the Indenture and a
subsequent acceleration of such indebtedness. In addition, as a result of these
covenants, the ability of the Company to respond to changing business and
economic conditions and to secure additional financing, if needed, may be
restricted significantly, and the Company may be prevented from engaging in
transactions that might otherwise be considered beneficial to the Company. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and "Description of the Exchange Notes -- Certain Covenants".
 
PAYMENT UPON A CHANGE OF CONTROL
 
     Upon the occurrence of a Change of Control, each holder of the Notes may
require the Company to repurchase all or a portion of such holder's Notes at
101% of the principal amount of the Notes, together with accrued and unpaid
interest, if any, to the date of repurchase. The Indenture requires that prior
to such a repurchase, the Company must either prepay all outstanding Senior
Indebtedness or obtain any required consents to such repurchase. The occurrence
of a Change of Control may result in a default under the Company's existing line
of credit or any future credit facilities. If a Change of Control were to occur,
the Company may not have the financial resources to prepay all of the Senior
Indebtedness, the Notes and the other Indebtedness that would become payable
upon the occurrence of such Change of Control or may be prohibited from
repurchasing the Notes. See "Description of the Exchange Notes -- Change of
Control".
 
ABSENCE OF A PUBLIC MARKET FOR THE NOTES
 
     The Outstanding Notes have not been registered under the Securities Act and
are subject to significant restrictions on resale. The Exchange Notes will
constitute a new issue of securities with no established trading market. The
Company does not intend to apply for listing of the Outstanding Notes or the
Exchange Notes on any securities exchange or to seek the admission thereof to
trading in the National Association of Securities Dealers Automated Quotation
System. The Initial Purchaser has informed the Company, that, following the
completion of the Exchange Offer, it currently intends to make a market in the
Notes. However, it is not
 
                                       13
<PAGE>   18
 
obligated to do so, and any such market making may be discontinued at any time
without notice. In addition, any such market-making activity will be subject to
the limits imposed by the Securities Act and the Exchange Act and may be limited
during the Exchange Offer or the pendency of the Shelf Registration Statement.
See "Description of the Exchange Notes" and "Exchange Offer; Registration
Statement". Accordingly, no assurance can be given that an active public or
other market will develop for the Exchange Notes or as to the liquidity of or
the trading market for the Exchange Notes.
 
DEPENDENCE ON OIL AND GAS INDUSTRY
 
     Demand for the Company's products and services depends to a large extent
upon the level of exploration and production activity in the oil and gas
industry and the industry's willingness to spend capital on drilling operations,
which in turn depends in part on oil and gas prices, expectations about future
prices, the cost of exploring for, producing and delivering oil and gas, the
discovery rate of new oil and gas reserves, domestic and international
political, military, regulatory and economic conditions and the ability of oil
and gas companies to raise capital. Prices for oil and gas historically have
been extremely volatile and have reacted to changes in the supply of and demand
for oil and natural gas, domestic and worldwide economic conditions and
political instability in oil producing countries. No assurance can be given that
current levels of oil and gas activities and capital expenditures on drilling
operations will be maintained or that demand for the Company's products and
services will reflect the level of such activities. Prices for oil and natural
gas are expected to continue to be volatile and affect the demand for and
pricing of the Company's products and services. A material decline in oil or
natural gas prices or activities could materially adversely affect the demand
for the Company's products and services and, therefore, the Company's results of
operations and financial condition.
 
COMPETITION
 
     The markets for the Company's products and services are highly competitive
and characterized by continual changes in technology. Many of the Company's
existing and potential competitors have substantially greater marketing,
distribution, financial and technical resources than the Company. There can be
no assurance that the Company's services, rentals and sales will continue at
current volumes or prices if its current competitors or new market entrants
introduce new products or services with better features, performance, prices or
characteristics than the Company's products and services. Competitive pressures
or other factors also may result in significant price competition that could
have a material adverse effect on the Company's results of operations and
financial condition. Furthermore, the competition among energy service companies
to employ the most reputable, qualified and experienced personnel is intense,
especially during times of increased drilling activity. There can be no
assurance that the Company will be able to continue to recruit and retain
highly-qualified personnel. Any difficulty in recruiting or retaining such
personnel could have a material adverse effect on the Company's results of
operations and financial condition. See "Business and
Properties -- Competition".
 
ASSIMILATION OF ACQUIRED BUSINESSES
 
     The ADI Acquisition and the DWS/DAMCO Acquisition have required the Company
to integrate additional personnel and operations and manage businesses that are
related to, but different from, Dailey's traditional directional drilling and
rental tool business. In particular, the operations of IDS historically have
operated at a net loss primarily due to limited distribution channels for IDS'
directional drilling technologies; therefore, the benefits of the IDS
Acquisition to the Company will be substantially dependent upon the Company's
ability to market the key technologies acquired in the IDS Acquisition through
the Company's existing infrastructure and distribution networks. No assurance
can be given that the Company will be successful in managing and incorporating
the acquired businesses into its existing operations or that such acquired
businesses will not require a disproportionate amount of management's attention.
The Company's failure to successfully incorporate the acquired businesses into
its existing operations, or the occurrence of unexpected costs or liabilities in
the acquired businesses, could have a material adverse effect on the Company's
financial condition and results of operations.
 
                                       14
<PAGE>   19
 
ACQUISITION STRATEGY
 
     The Company is actively seeking strategic acquisitions that will provide
additional and complementary products and services. Nevertheless, there can be
no assurance that attractive acquisitions will be available to the Company at
reasonable prices or that any acquisition achieved will be consummated on
favorable terms to the Company or ultimately will prove to be a successful
undertaking by the Company. The Company may be required, to the extent permitted
by the Indenture and the Credit Facility, to incur substantial indebtedness to
finance future acquisitions. Such additional debt service requirements may
represent a significant burden on the Company's results of operations and
financial condition. There also 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 line of business. Any inability
on the part of the Company to find and acquire attractive businesses and assets
and to integrate and manage such acquired businesses and assets could have a
material adverse effect on the Company's results of operations and financial
condition. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations -- Liquidity and Capital Resources".
 
DEPENDENCE ON KEY PERSONNEL
 
     The Company believes that its success will depend to a significant extent
upon the continued services of certain key operating personnel, particularly
James F. Farr, President and Chief Executive Officer of the Company. The
Company's existing employment agreement with Mr. Farr has an initial term
expiring on December 31, 2000. The loss of the services of Mr. Farr could have a
material adverse effect on the Company's business and future prospects. The
Company does not maintain key employee insurance. See "Management".
 
OPERATING RISKS AND INSURANCE
 
     The operations of the Company's customers are subject to hazards inherent
in the oil and gas industry, such as fires, explosions, craterings, blowouts and
oil spills, which can cause serious personal injury or loss of life, damage to
or destruction of property, equipment, the environment and marine life, and
suspension of operations. Claims for loss of oil and gas production and damages
to formations can occur in drilling and workover operations. If a catastrophic
event were to occur at a location where the Company's products or services are
being provided, the Company could be named as a defendant or third-party
defendant in lawsuits asserting potentially large claims. The Company maintains
insurance coverage that it believes to be customary in the industry against
certain of these hazards, however, such insurance provides for substantial
deductibles and premium adjustments based on claims experience and excludes
coverage for damages resulting from environmental damage and pollution or breach
of contract or claims based on alleged fraud or deceptive trade practices.
Insurance cannot provide complete protection against casualty losses. There can
be no assurance that the Company will be able to maintain adequate insurance in
the future at rates it considers reasonable or that insurance will continue to
be available on terms as favorable as those of its existing arrangements. A
claim or suit against the Company in excess of the coverage limits maintained by
the Company or for which the Company is not insured could have a material
adverse effect on the Company's financial condition and results of operations.
See "Business and Properties -- Operating Risks and Insurance".
 
RISK OF INTERNATIONAL OPERATIONS
 
     The Company's international operations (including Canada), which
represented approximately 45% of the total pro forma revenues of the Company for
the six months ended October 31, 1997, are subject to special risks inherent in
doing business outside the United States, including governmental instability,
war and other international conflicts, civil and labor disturbances,
requirements of local ownership, partial or total expropriation,
nationalization, currency devaluation, foreign exchange controls, and foreign
laws and policies, each of which may limit the movement of assets or funds or
result in the deprivation of contract rights or the taking of property without
fair compensation. Although the Company maintains political risk insurance to
protect itself from such risks, such insurance may be insufficient to protect
the Company in all circumstances, and any failure to do so could have a material
adverse effect on the Company's results of operations and financial
                                       15
<PAGE>   20
 
condition. In addition, although most of the Company's international revenues
are derived from transactions denominated in United States dollars, the Company
has and likely will continue to conduct some business in currencies other than
the United States dollar. The Company currently does not hedge against foreign
currency fluctuations. Accordingly, its profitability has been and will continue
to be affected by fluctuations in foreign exchange rates. The Company believes
that revenues from transactions denominated in foreign currencies will increase
as a percentage of total revenues due to the ADI Acquisition, the DWS/DAMCO
Acquisition and the IDS Acquisition and continued expansion of the Company's
international operations. In addition, collections and recovery of rental tools
from international customers and agents may prove more difficult due to the
uncertainties of foreign law and judicial procedure. The Company may therefore
experience significant difficulty resulting from the political or judicial
climate in countries in which it operates. From time to time the United States
has passed laws and imposed regulations prohibiting or restricting trade with
certain nations. There can be no assurance that future laws and regulations will
not limit materially the Company's international business. See "Business and
Properties -- International Operations" and "Management's Discussion and
Analysis of Financial Condition and Results of Operations -- Inflation and
Foreign Exchange".
 
TECHNOLOGICAL EVOLUTION AND PRODUCT OBSOLESCENCE
 
     The markets for the Company's specialized services and downhole tools are
characterized by continual technological developments that have resulted in, and
likely will continue to result in, substantial improvements in the scope and
quality of directional drilling and underbalanced drilling services and product
function and performance. Whether the Company can develop and produce
successfully, on a timely basis, new and enhanced downhole tools that embody new
technology, meet evolving industry standards and practice, and achieve levels of
capability and price that are acceptable to its customers will be significant
factors in determining the Company's ability to compete. There can be no
assurance that the Company will not encounter resource constraints or technical
or other difficulties that could delay introduction of new products and services
in the future. If the Company is unable, for technological or other reasons, to
develop and commercialize competitive products in a timely manner in response to
changes in the directional drilling, underbalanced drilling or rental tool
industries, its results of operations and financial condition could be
materially adversely affected.
 
INTELLECTUAL PROPERTY
 
     Certain features of the Company's products and services have been granted
United States and foreign patent protection, or have patent applications
pending. There can be no assurance that the Company's patents will prove
enforceable, that any patents for which the Company has made application will be
issued or that competitors will not develop functionally similar products
outside the protection of any patents the Company has or may obtain.
Furthermore, after the Company's patents expire, the Company's competitors could
develop products substantially similar to the Company's products and services.
See "Business and Properties -- Intellectual Property".
 
VENDOR SUPPLY INTERRUPTION
 
     The Company assembles all of, and manufactures a portion of the components
for, its downhole tools. The manufacturing processes performed by the Company
require a ready supply of high-quality, special alloy steel. Consistent with the
recent upturn in the demand for steel and other raw materials used in the oil
and gas industry, the Company has experienced longer lead times for delivery of
raw materials, primarily steel, which requires the Company to predict further in
advance its needs for such materials. While the Company has not experienced
significant supply or quality control problems to date with its various
suppliers of steel and other raw materials, any supply or quality control
problems could significantly affect the Company's ability to meet production
schedules and commitments, which could have a material adverse effect on the
Company's results of operations. See "Business and Properties -- Manufacturing
and Maintenance".
 
                                       16
<PAGE>   21
 
RELIANCE ON CERTAIN SUPPLIERS
 
     Most of the Company's downhole tools incorporate certain products or
technology supplied in part by third parties. Although the Company is not
presently experiencing and does not anticipate any significant supply or quality
control problems with its vendors, such problems, if they were to occur, could
have a material adverse effect on the Company's ability to meet future
production and sales commitments, which could adversely affect the Company's
results of operations. In addition, during the past five years, one vendor has
been the Company's only supplier of filters used in the Company's hydraulic
downhole tools. The Company has not identified alternative suppliers for such
filters. To date, the Company has not experienced supply problems with this
vendor; however, any difficulty with such supplier combined with any difficulty
in finding and utilizing alternative sources for these filters could have a
material adverse effect on the Company's results of operations. See "Business
and Properties -- Manufacturing and Maintenance".
 
     The Company purchases all of its MWD units used in connection with its
directional drilling services from a single supplier. The Company believes that
reliable MWD units are available for third-party purchase from only a few
vendors worldwide. Although the Company has not experienced significant supply
or quality control problems to date with its supplier, there can be no assurance
that the Company will be able to purchase reliable, high-quality MWD units from
other vendors at competitive prices and terms. Any difficulty in obtaining MWD
units from its supplier, as a result of manufacturing delays or other reasons,
could have a material adverse effect on the Company's results of operation and
financial condition. See "Business and Properties -- Drilling
Services -- Directional Drilling Services".
 
RELATIONSHIP WITH LAWRENCE
 
     The Company currently has two classes of voting stock, Class A Common Stock
and Class B Common Stock (together, the "Common Stock"). Each share of Class A
Common Stock is entitled to one vote and each share of Class B Common Stock is
entitled to seven votes, with both classes of Common Stock voting together as a
single class. Lawrence Industries, Inc. ("Lawrence"), which is owned by the
Chairman of the Board of the Company and trusts for his family, beneficially
owns all of the Class B Common Stock, and controls approximately 89% of the
combined voting power of the outstanding Common Stock. Accordingly, Lawrence and
the Company's Chairman of the Board, J.D. Lawrence, will be in a position to
elect the Company's board of directors and otherwise control the business
policies of the Company. See "Certain Relationships and Related Transactions"
and "Securities Ownership of Management and Principal Stockholder".

                               THE EXCHANGE OFFER
 
PURPOSE AND EFFECT OF THE EXCHANGE OFFER
 
     The Outstanding Notes were issued by the Company on February 13, 1998, to
the Initial Purchaser pursuant to the Purchase Agreement. The Initial Purchaser
subsequently placed the Outstanding Notes with qualified institutional buyers in
reliance on Rule 144A under the Securities Act. As a condition of the purchase
of the Outstanding Notes by the Initial Purchaser, the Company and the
Subsidiary Guarantors entered into the Registration Rights Agreement with the
Initial Purchaser, which requires, among other things, that the Company file
with the Commission a registration statement under the Securities Act with
respect to an offer by the Company to the holders of the Outstanding Notes to
issue and deliver to such holders, in exchange for Outstanding Notes, a like
principal amount of Exchange Notes. The Company is required to use its best
efforts to cause the Registration Statement relating to the Exchange Offer to be
declared effective by the Commission under the Securities Act and commence the
Exchange Offer and use best efforts to issue, on or prior to the Exchange Date,
the Exchange Notes. The Exchange Notes are to be issued without a restrictive
legend and may be reoffered and resold by the holder without restrictions or
limitations under the Securities Act (other than any such holder that is an
"affiliate" of the Company within the meaning of Rule 405 under the Securities
Act). A copy of the Registration Rights Agreement has been filed as an exhibit
to the Registration Statement of which this Prospectus is a part. The term
"Holder" with respect to the Exchange Offer means any person in whose name the
Outstanding Notes are registered on the books of the Company or any other person
who has obtained a properly completed bond power from the registered holder.
 
TERMS OF THE EXCHANGE OFFER
 
     Upon the terms and subject to the conditions set forth in this Prospectus
and in the Letter of Transmittal, the Company will accept any and all
Outstanding Notes validly tendered and not withdrawn prior to 5:00 p.m., New
York City time, on the Expiration Date. On the Exchange Date, the Company will
issue $1,000 principal amount of Exchange Notes in exchange for $1,000 principal
amount of Outstanding Notes accepted in the Exchange Offer. Holders may tender
some or all of their Outstanding Notes pursuant to the Exchange Offer. However,
Outstanding Notes may be tendered only in integral multiples of $1,000.
 
     The form and terms of the Exchange Notes are the same as the form and terms
of the Outstanding Notes except that (i) the Exchange Notes have been registered
under the Securities Act and hence will not bear legends restricting the
transfer thereof and (ii) the holders of the Exchange Notes will not be entitled
to certain rights under the Registration Rights Agreement. The Exchange Notes
will evidence the same debt as the Outstanding Notes and will be entitled to the
benefits of the Indenture.
 
     As of the date of this Prospectus, $275,000,000 aggregate principal amount
of the Outstanding Notes was outstanding, all of which is registered in the name
of Cede & Co., as nominee for the Depository Trust Company. Holders of
Outstanding Notes do not have any appraisal or dissenters' rights under the
General Corporation Law of Delaware or the Indenture in connection with the
Exchange Offer. The Company intends to conduct the Exchange Offer in accordance
with the applicable requirements of the Exchange Act and the rules and
regulations of the Commission thereunder, including Rule 14e-1 thereunder.
 
     The Company shall be deemed to have accepted validly tendered Outstanding
Notes when, as and if the Company has given oral or written notice thereof to
the Exchange Agent. The Exchange Agent will act as agent for the tendering
Holders for the purpose of receiving the Exchange Notes from the Company.
 
     If any tendered Outstanding Notes are not accepted for exchange because of
an invalid tender, the occurrence of certain other events set forth herein or
otherwise, the certificates for any such unaccepted
 
                                       18
<PAGE>   23
 
Outstanding Notes will be returned, without expense, to the tendering Holder
thereof as promptly as practicable after the Expiration Date.
 
     Holders who tender Outstanding Notes in the Exchange Offer will 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
Outstanding Notes pursuant to the Exchange Offer. The Company will pay all
charges and expenses, other than transfer taxes in certain circumstances, in
connection with the Exchange Offer. See "-- Fees and Expenses".
 
INTEREST ON THE EXCHANGE NOTES
 
     The Exchange Notes will bear interest from the date of issuance of the
Exchange Notes. Interest on the Outstanding Notes that are tendered in exchange
for the Exchange Notes that has accrued from February 13, 1998, the date of
issuance of the Outstanding Notes, through the Exchange Date will be payable on
or before August 15, 1998. Interest on the Exchange Notes will be payable
semi-annually on each February 15 and August 15, commencing August 15, 1998.
 
PROCEDURES FOR TENDERING
 
     Only a Holder of Outstanding Notes may tender such Outstanding Notes in the
Exchange Offer. To tender in the Exchange Offer, a Holder must complete, sign
and date the Letter of Transmittal, or a facsimile thereof, have the signatures
thereon guaranteed if required by the Letter of Transmittal and mail or
otherwise deliver such Letter of Transmittal or such facsimile, together with
the Outstanding Notes and any other required documents, to the Exchange Agent
prior to 5:00 p.m., New York City time, on the Expiration Date. To be tendered
effectively, the Outstanding Notes, Letter of Transmittal and other required
documents must be received by the Exchange Agent at the address set forth below
under "Exchange Agent" prior to 5:00 p.m., New York City time, on the Expiration
Date. Delivery of the Outstanding Notes may be made by book-entry transfer in
accordance with the procedures described below. Confirmation of such book-entry
transfer must be received by the Exchange Agent prior to the Expiration Date.
 
     By executing the Letter of Transmittal, each Holder will make to the
Company the representation set forth below in the second paragraph under the
heading "Resale of Exchange Notes".
 
     The tender by a Holder and the acceptance thereof by the Company will
constitute the agreement between such Holder and the Company in accordance with
the terms and subject to the conditions set forth herein and in the Letter of
Transmittal.
 
     THE METHOD OF DELIVERY OF OUTSTANDING NOTES AND THE LETTER OF TRANSMITTAL
AND ALL OTHER REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE ELECTION AND
RISK OF THE HOLDER. INSTEAD OF DELIVERY BY MAIL, IT IS RECOMMENDED THAT HOLDERS
USE AN OVERNIGHT OR HAND DELIVERY SERVICE. IN ALL CASES, SUFFICIENT TIME SHOULD
BE ALLOWED TO ASSURE DELIVERY TO THE EXCHANGE AGENT BEFORE THE EXPIRATION DATE.
NO LETTER OF TRANSMITTAL OR OUTSTANDING NOTES SHOULD BE SENT TO THE COMPANY.
HOLDERS MAY REQUEST THEIR RESPECTIVE BROKERS, DEALERS, COMMERCIAL BANKS, TRUST
COMPANIES OR NOMINEES TO EFFECT THE ABOVE TRANSACTIONS FOR SUCH HOLDERS.
 
     Any beneficial owner whose Outstanding Notes are registered in the name of
a broker, dealer, commercial bank, trust company or other nominee and who wishes
to tender should contact the registered Holder promptly and instruct such
registered Holder to tender on such beneficial owner's behalf.
 
     Signatures on the Letter of Transmittal or a notice of withdrawal, as the
case may be, must be guaranteed by an Eligible Institution (as defined below)
unless the Outstanding Notes tendered pursuant thereto are tendered (i) by a
registered Holder who has not completed the box entitled "Special Registration
Instructions" or "Special Delivery Instructions" on the Letter of Transmittal or
(ii) for the account of an Eligible Institution. In the event that signatures on
a Letter of Transmittal or a notice of withdrawal, as the case may be, are
required to be guaranteed, such guarantee must be by a member firm of a
registered national
                                       19
<PAGE>   24
 
securities exchange or of the National Association of Securities Dealers, Inc.,
a commercial bank or trust company having an office or correspondent in the
United States or an "eligible guarantor institution" within the meaning of Rule
17Ad-15 under the Exchange Act (an "Eligible Institution").
 
     If the Letter of Transmittal is signed by a person other than the
registered Holder of any Outstanding Notes listed therein, such Outstanding
Notes must be endorsed or accompanied by a properly completed bond power, signed
by such registered Holder as such registered Holder's name appears on such
Outstanding Notes with the signature thereon guaranteed by an Eligible
Institution.
 
     If the Letter of Transmittal or any Outstanding Notes or bond powers 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, evidence satisfactory to the Company of their authority to so act must
be submitted with the Letter of Transmittal.
 
     The Company understands that the Exchange Agent will make a request
promptly after the date of this Prospectus to establish accounts with respect to
the Exchange Notes at the DTC (the "Book-Entry Transfer Facility") for the
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 the Outstanding Notes
by causing such Book-Entry Transfer Facility to transfer such Outstanding Notes
into the Exchange Agent's account with respect to the Outstanding Notes in
accordance with the Book-Entry Transfer Facility's procedures for such transfer.
Although delivery of the Outstanding 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 properly completed and duly executed 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; provided, however, that a
participant in DTC's book-entry system may, in accordance with DTC's Automated
Tender Offer Program procedures and in lieu of physical delivery to the Exchange
Agent of a Letter of Transmittal, electronically acknowledge its receipt of, and
agreement to be bound by, the terms of the Letter of Transmittal. Delivery of
documents to the Book-Entry Transfer Facility does not constitute delivery to
the Exchange Agent.
 
     All questions as to the validity, form, eligibility (including time of
receipt), acceptance and withdrawal of tendered Outstanding Notes will be
determined by the Company in its sole discretion, which determination will be
final and binding. The Company reserves the absolute right to reject any and all
Outstanding Notes not properly tendered or any Outstanding 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,
irregularities or conditions of tender as to particular Outstanding Notes. The
Company's interpretation of the terms and conditions of the Exchange Offer
(including the instructions in the Letter of Transmittal) will be final and
binding on all parties. Unless waived, any defects or irregularities in
connection with tenders of Outstanding Notes must be cured within such time as
the Company shall determine. Although the Company intends to notify Holders of
defects or irregularities with respect to tenders of Outstanding Notes, neither
the Company, the Exchange Agent nor any other person shall incur any liability
for failure to give such notification. Tenders of Outstanding Notes will not be
deemed to have been made until such defects or irregularities have been cured or
waived. Any Outstanding Notes received by the Exchange Agent that are not
properly 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,
unless other provided in the Letter of Transmittal, as soon as practicable
following the Expiration Date.

GUARANTEED DELIVERY PROCEDURES
 
     Holders who wish to tender their Outstanding Notes and (i) whose
Outstanding Notes are not immediately available, (ii) who cannot deliver their
Outstanding Notes, the Letter of Transmittal or any other required documents to
the Exchange Agent or (iii) who cannot complete the procedures for book-entry
transfer, prior to the Expiration Date, may effect a tender if:
 
          (a) the tender is made through an Eligible Institution;
 
          (b) prior to the Expiration Date, the Exchange Agent receives from
     such 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, the certificate number(s)
     of such Outstanding Notes and the principal amount of Outstanding Notes
     tendered, stating that the tender is being made thereby and guaranteeing
     that, within five New York Stock Exchange trading days after the Expiration
     Date, the Letter of Transmittal (or facsimile thereof), together with the
     certificate(s) representing the Outstanding Notes (or a confirmation of
     book-entry transfer of such Outstanding Notes into the Exchange Agent's
     account at the Book-Entry Transfer Facility) and any other documents
     required by the Letter of Transmittal, will be deposited by the Eligible
     Institution with the Exchange Agent; and
 
          (c) such properly completed and executed Letter of Transmittal (or
     facsimile thereof), as well as the certificate(s) representing all tendered
     Outstanding Notes in proper form for transfer (or a confirmation of
     book-entry transfer of such Outstanding Notes into the Exchange Agent's
     account at the Book-Entry Transfer Facility) and all other documents
     required by the Letter of Transmittal, are received by the Exchange Agent
     within three New York Stock Exchange trading days after the Expiration
     Date.
 
     Upon request to the Exchange Agent, a Notice of Guaranteed Delivery will be
sent to Holders who wish to tender their Outstanding Notes according to the
guaranteed delivery procedures set forth above.
 
WITHDRAWALS OF TENDERS
 
     Except as otherwise provided herein, tenders of Outstanding Notes may be
withdrawn at any time prior to 5:00 p.m., New York City time, on the Expiration
Date.
 
     To withdraw a tender of Outstanding Notes in the Exchange Offer, a written
or facsimile transmission notice of withdrawal 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. Any such notice of withdrawal must (i) specify the name of
the person having deposited the Outstanding Notes to be withdrawn (the
"Depositor"), (ii) identify the Outstanding Notes to be withdrawn (including the
certificate number(s) and principal amount of such Outstanding Notes, or, in the
case of Outstanding Notes transferred by book-entry transfer, the name and
number of the account at the Book-Entry Transfer Facility to be credited), (iii)
be signed by the Holder in the same manner as the original signature on the
Letter of Transmittal by which such Outstanding Notes were tendered (including
any required signature guarantees) or be accompanied by documents of transfer
sufficient to have the Trustee with respect to the Outstanding Notes register
the transfer of such Outstanding Notes into the name of the person withdrawing
the tender, (iv) specify the name in which any such Outstanding Notes are to be
registered, if different from that of the Depositor and (v) if applicable
because the Outstanding Notes have been tendered pursuant to book-entry
procedures, specify the name and number of the participant's account at DTC to
be credited, if different from that of the Depositor. All questions as to the
validity, form and eligibility (including time of receipt) of such notices will
be determined by the Company, whose determination shall be final and binding on
all parties. Any Outstanding Notes so withdrawn will be deemed not to have been
validly tendered for purposes of the Exchange Offer and no Exchange Notes will
be issued with respect thereto unless the Outstanding Notes so withdrawn are
validly retendered. Any Outstanding Notes which have been tendered but which are
not accepted for exchange, will be returned to the Holder thereof without cost
to such Holder as soon as practicable after withdrawal, rejection of tender or
termination of the Exchange Offer. Properly withdrawn Outstanding Notes may be
retendered by following
                                       21
<PAGE>   26
 
one of the procedures described above under "-- Procedures for Tendering" at any
time prior to the Expiration Date.
 
CONDITIONS
 
     Notwithstanding any other term of the Exchange Offer, the Company shall not
be required to accept for exchange, or to issue Exchange Notes for, any
Outstanding Notes, and may terminate or amend the Exchange Offer as provided
herein before the acceptance of such Outstanding Notes, if:
 
          (a) any action or proceeding is instituted or threatened in any court
     or by or before any governmental agency with respect to the Exchange Offer
     that might materially impair the ability of the Company to proceed with the
     Exchange Offer or any material adverse development has occurred in any
     existing action or proceeding with respect to the Company or any of its
     subsidiaries; or
 
          (b) any change, or any development involving a prospective change, in
     the business or financial affairs of the Company or any of its subsidiaries
     has occurred that might materially impair the ability of the Company to
     proceed with the Exchange Offer; or
 
          (c) any law, statute, rule, regulation or interpretation by the staff
     of the Commission is proposed, adopted or enacted that might materially
     impair the ability of the Company to proceed with the Exchange Offer or
     materially impair the contemplated benefits of the Exchange Offer to the
     Company; or
 
          (d) any governmental approval has not been obtained, which approval
     the Company shall, in its sole discretion, deem necessary for the
     consummation of the Exchange Offer as contemplated hereby.
 
     If the Company determines in good faith and in the exercise of its
reasonable discretion that any of the conditions are not satisfied, the Company
may (i) refuse to accept any Outstanding Notes and return all tendered
Outstanding Notes to the tendering Holders, (ii) extend the Exchange Offer and
retain all Outstanding Notes tendered prior to the expiration of the Exchange
Offer, subject, however, to the rights of Holders to withdraw such Outstanding
Notes (see "-- Withdrawal of Tenders") or (iii) waive such unsatisfied
conditions with respect to the Exchange Offer and accept all properly tendered
Outstanding Notes which have not been withdrawn. If such waiver constitutes a
material change to the Exchange Offer, the Company will promptly disclose such
waiver by means of a prospectus supplement that will be distributed to the
registered Holders, and, depending upon the significance of the waiver and the
manner of disclosure to the registered Holders, the Company will extend the
Exchange Offer for a period of five to 10 business days if the Exchange Offer
would otherwise expire during such five to 10 day period.

</TABLE>
 
FEES AND EXPENSES
 
     The expenses of soliciting tenders pursuant to the Exchange Offer will be
borne by the Company. The principal solicitation is being made by mail; however,
additional solicitation may be made by telegraph, telephone or in person by
officers and regular employees of the Company and its affiliates.
 
     The Company has not retained any dealer-manager in connection with the
Exchange Offer and will not make any payments to brokers or other soliciting
acceptances of the Exchange Offer. The Company, however, will pay the Exchange
Agent reasonable and customary fees for its services and registration expenses,
including fees and expenses of the Trustee, filing fees, blue sky fees and
printing and distribution expenses.
 
     The Company will pay all transfer taxes, if any, applicable to the exchange
of the Outstanding Notes pursuant to the Exchange Offer. If, however,
certificates representing the Exchange Notes or the Outstanding Notes for the
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 person signing the
Letter of Transmittal, or if a transfer tax is imposed for any reason other than
the exchange of the Outstanding Notes pursuant to the Exchange Offer, then the
amount of any such transfer taxes (whether imposed on the registered Holder or
any other person) will be payable by the tendering Holder.
 
ACCOUNTING TREATMENT
 
     The Exchange Notes will be recorded at the same carrying value as the
Outstanding Notes, which is face value as adjusted for original issue discount,
as reflected in the Company's accounting records on the date of exchange.
Accordingly, no gain or loss for accounting purposes will be recognized. The
expenses of the Exchange Offer will be amortized over the term of the Exchange
Notes.
 
RESALE OF EXCHANGE NOTES
 
     Based on an interpretation by the staff of the Commission set forth in
no-action letters issued to third parties, the Company believes that Exchange
Notes issued pursuant to the Exchange Offer in exchange for Outstanding Notes
may be offered for resale, resold and otherwise transferred by any holder of
such Exchange
 
                                       23
<PAGE>   28
 
Notes (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 provisions of the Securities Act, provided
that such Exchange Notes are acquired in the ordinary course of such holder's
business and such holder does not intend to participate and has no arrangement
or understanding with any person to participate in the distribution of such
Exchange Notes. Any holder who tenders in the Exchange Offer with the intention
to participate, or for the purpose of participating, in a distribution of the
Exchange Notes may not rely on the position of the staff of the Commission
enunciated in Exxon Capital Holdings Corporation (available April 13, 1989) and
Morgan Stanley & Co., Incorporated (June 5, 1991), or similar no-action letters,
but rather must comply with the registration and prospectus delivery
requirements of the Securities Act in connection with any resale transaction. In
addition, any such resale transaction should be covered by an effective
registration statement containing the selling security holders information
required by Item 507 of Regulation S-K of the Securities Act. Each broker-dealer
that receives Exchange Notes for its own account in exchange for Outstanding
Notes, where such Outstanding 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 Exchange
Notes. See "Plan of Distribution".
 
     By tendering in the Exchange Offer, each Holder will represent to the
Company that, among other things, (i) the Exchange Notes acquired pursuant to
the Exchange Offer are being obtained in the ordinary course of business of the
person receiving such Exchange Notes, whether or not such person is a Holder,
(ii) neither the Holder nor any such other person has an arrangement or
understanding with any person to participate in the distribution of such
Exchange Notes and (iii) the Holder and such other person acknowledge that if
they participate in the Exchange Offer for the purpose of distributing the
Exchange Notes (a) they must, in the absence of an exemption therefrom, comply
with the registration and prospectus delivery requirements of the Securities Act
in connection with any resale of the Exchange Notes and cannot rely on the
no-action letters referenced above and (b) failure to comply with such
requirements in such instance could result in such Holder incurring liability
under the Securities Act for which such Holder is not indemnified by the
Company. Further, by tendering in the Exchange Offer, each Holder that may be
deemed an "affiliate" (as defined under Rule 405 of the Securities Act) of the
Company will represent to the Company that such Holder understands and
acknowledges that the Exchange Notes may not be offered for resale, resold or
otherwise transferred by that Holder without registration under the Securities
Act or an exemption therefrom.
 
     As set forth above, affiliates of the Company are not entitled to rely on
the foregoing interpretations of the staff of the Commission with respect to
resales of the Exchange Notes without compliance with the registration and
prospectus delivery requirements of the Securities Act.
 
PRIVATE EXCHANGE NOTES
 
     The Registration Rights Agreement provides that if, prior to consummation
of the Exchange Offer, the Initial Purchaser holds any Outstanding Notes
acquired by it and having, or which are reasonably likely to be determined to
have, the status of an unsold allotment in the initial distribution, or any
other holder of Outstanding Notes is not entitled to participate in the Exchange
Offer for certain reasons, the Company upon the request of such Initial
Purchaser or any such holder shall, simultaneously with the delivery of the
Exchange Notes in the Exchange Offer, issue and deliver to the Initial Purchaser
and any such holder, in exchange (the "Private Exchange") for such Outstanding
Notes held by the Initial Purchaser and any such holder, Private Exchange Notes.
Any Private Exchange Notes will be issued pursuant to the same indenture as the
Exchange Notes. The Private Exchange Notes are not covered by the registration
statement of which this Prospectus is a part and are not being offered hereby.
Any Private Exchange Notes will be entitled to all the rights and subject to all
the limitations applicable thereto under the Indenture, and will be subject to
the same restrictions on transfer applicable to untendered Outstanding Notes.
See "-- Consequences of Failure to Exchange". However, pursuant to the
Registration Rights Agreement, holders of Private Exchange Notes have certain
rights to require the Company to file and maintain a shelf registration

CONSEQUENCES OF FAILURE TO EXCHANGE
 
     As a result of the making of this Exchange Offer, the Company will have
fulfilled one of its obligations under the Registration Rights Agreement, and,
except as described under "-- Shelf Registration Statement", Holders of
Outstanding Notes who do not tender their Outstanding Notes will not have any
further registration rights under the Registration Rights Agreement or
otherwise. Accordingly, any Holder of Outstanding Notes that does not exchange
that Holder's Outstanding Notes for Exchange Notes will continue to hold the
untendered Outstanding Notes and will be entitled to all the rights and
limitations applicable thereto under the Indenture, except to the extent such
rights or limitations that, by their terms, terminate or cease to have further
effectiveness as a result of the Exchange Offer.
 
     The Outstanding Notes that are not exchanged for Exchange Notes pursuant to
the Exchange Offer will remain restricted securities. Accordingly, such
Outstanding Notes may be resold only (i) to the Company (upon redemption thereof
or otherwise), (ii) pursuant to an effective registration statement under the
Securities Act, (iii) so long as the Outstanding Notes are eligible for resale
pursuant to Rule 144A, to a qualified institutional buyer within the meaning of
Rule 144A under the Securities Act in a transaction meeting the requirements of
Rule 144A, (iv) outside the United States to a foreign person pursuant to the
exemption from the registration requirements of the Securities Act provided by
Regulation S thereunder, (v) to an institutional accredited investor that, prior
to such transfer, furnishes to U.S. Trust Company of Texas, N.A., as trustee, a
signed letter containing certain representations and agreements relating to the
restrictions on transfer of the Outstanding Notes evidenced thereby (the form of
which letter can be obtained from such trustee) or (vi) pursuant to another
available exemption from the registration requirements of the Securities Act, in
each case in accordance with any applicable securities laws of any state of the
United States.
 
     Accordingly, to the extent that Outstanding Notes are tendered and accepted
in the Exchange Offer, the trading market for the untendered Outstanding Notes
could be adversely affected.
 
SHELF REGISTRATION STATEMENT
 
     If (i) the Company is not permitted to consummate the Exchange Offer
because the Exchange Offer is not permitted by any applicable law or applicable
interpretation of the Commission or the staff of the Commission or (ii) any
holder of an Outstanding Note notifies the Company on or prior to the Exchange
Date that (A) due to a change in law or policy it is not entitled to participate
in the Exchange Offer, (B) due to a change in law or policy it may not resell
the Exchange Notes acquired by it in the Exchange Offer to the public without
delivering a prospectus and this prospectus is not appropriate or available for
such resales by such holder or (C) it is a broker-dealer that owns Outstanding
Notes (including an initial purchaser that holds Outstanding Notes as part of an
unsold allotment from the original offering of the Outstanding Notes) acquired
directly from the Company or an affiliate of the Company or (iii) any holder of
Private Exchange Notes so requests within 120 days after the consummation of the
Private Exchange, the Company has agreed to file and maintain a registration
statement that would allow resales of transfer restricted Outstanding Notes,
Exchange Notes or Private Exchange Notes owned by such holders.
 
OTHER
 
     Participation in the Exchange Offer is voluntary and holders should
carefully consider whether to accept. Holders of the Outstanding Notes are urged
to consult their financial and tax advisors in making their own decision on what
action to take.
 
     The Company may in the future seek to acquire untendered Outstanding Notes
in open market or privately negotiated transactions, through subsequent exchange
offers or otherwise. The Company has no present plans to acquire any Outstanding
Notes that are not tendered in the Exchange Offer or to file a registration
statement to permit resales of any untendered Outstanding Notes, except for the
filing, if required, of the Shelf Registration Statement.

                                  THE COMPANY
 
     The Company is an integrated provider of specialty services and
technologically-advanced downhole tools to the oil and gas industry on a
worldwide basis. The Company's services include (i) directional drilling
services, (ii) underbalanced drilling services, (iii) electric wireline and
tubing conveyed perforating services, (iv) tubular testing and handling services
and (v) downhole tool rental. The Company has recently expanded its operations
significantly through strategic acquisitions and internal growth. This strategy
has enabled the Company to expand and diversify the range of services and
products it provides to the oil and gas industry and to effect cross marketing
of its service and product lines. Dailey began operations in the fishing tool
business in 1945 as Dailey Oil Tools and changed its name to Dailey Petroleum
Services Corp. in 1984. In October 1997, Dailey changed its name to Dailey
International Inc.
 
     In August 1996, Dailey completed an initial public offering of its Class A
Common Stock (the "1996 IPO") and immediately embarked on a focused growth
strategy aimed at expanding the drilling services and fleet of downhole tools it
offers by increasing its investment in additional downhole tools and acquiring
complementary businesses and assets. To date, this growth strategy has resulted
in the Company increasing its revenues to $120.1 million on a pro forma basis
for the year ended April 30, 1997, from $58.9 million on an historical basis for
the year ended April 30, 1996.
 
     In June 1997, Dailey acquired ADI, a leading worldwide provider of air
drilling services to the oil and gas industry. In January 1998, Dailey acquired
the operating assets and liabilities of DWS/DAMCO, specialized providers of
electric wireline and tubular services in the U.S. Gulf of Mexico region and, to
a lesser extent, in Nigeria. In March 1997, the Company acquired the outstanding
capital stock of IDS, a directional drilling service company. The Company
believes these acquisitions provide it with significant operational benefits,
including geographic expansion and cross-marketing opportunities.
 
     The Company's executive offices are located in Conroe, Texas, approximately
50 miles north of Houston. The Company's address is 2507 North Frazier, P.O. Box
1863, Conroe, Texas 77305, and its telephone number is (281) 350-3399.
 
                                USE OF PROCEEDS
 
     The Exchange Offer is intended to satisfy certain of the Company's
obligations under the Purchase Agreement and the Registration Rights Agreement.
The Company will not receive any cash proceeds from the issuance of the Exchange
Notes offered hereby. In consideration for issuing the Exchange Notes
contemplated in this Prospectus, the Company will receive Outstanding Notes in
like principal amount, the form and terms of which are the same as the form and
terms of the Exchange Notes (which they replace), except as otherwise described
herein. The Outstanding Notes surrendered in exchange for Exchange Notes will be
retired and canceled and cannot be reissued. Accordingly, issuance of the
Exchange Notes will not result in any increase or decrease in the indebtedness
of the Company.
 
     The net proceeds to the Company from the issuance of the Outstanding Notes
were approximately $267.7 million after deducting the estimated fees and
expenses of the issuance of the Outstanding Notes.
 
     The Company used approximately $133.5 million of the net proceeds from the
issuance of the Outstanding Notes to purchase all of the outstanding Old Notes
from the Initial Purchaser and $7.5 million to repay outstanding borrowings
under the Credit Facility. Proceeds from the issuance of the Old Notes were used
to repay debt incurred in connection with the ADI Acquisition and to finance a
substantial portion of the DWS/DAMCO Acquisition and for capital expenditures.
The Old Notes matured on August 15, 2007 and were issued pursuant to an
indenture with covenants similar to those contained in the Indenture. The Credit
Facility provides for borrowings of up to the lesser of $15 million or an amount
calculated utilizing a loan formula based upon the level of eligible accounts
receivable, which was approximately $11.3 million at December 31, 1997. As of
January 31, 1998, the outstanding principal balance of advances made pursuant to
the Credit Facility was $7.5 million, which were utilized to fund a portion of
the purchase price for the DWS/DAMCO Acquisition. Interest on the Credit
Facility is variable and fluctuates based on leverage ratios at a variable
margin over the applicable prime rate or at a LIBOR-based rate.
                                       26
<PAGE>   31
 
     The Company intends to use approximately $26.9 million of the net proceeds
from the issuance of the Outstanding Notes for discretionary capital
expenditures to increase its fleet of downhole tools and for equipment utilized
in its operations. The Company's inventory expansion will focus primarily upon
MWD units, drilling jars and fishing jars, and mud motors, compressors and mist
pumps utilized in the Company's air drilling operations and tongs utilized in
its tubular testing and handling services. Since the equipment utilized in the
Company's operations can be transported cost effectively between its main
geographic markets, the Company intends to utilize its expanded inventory in all
or some of its markets depending on demand for such tools and equipment at any
given time.
 
     A portion of the remaining net proceeds were utilized to fund the cash
portion of the purchase price for IDS and to repay a portion of IDS' outstanding
debt. The remaining net proceeds from the issuance of the Outstanding Notes are
expected to be used by the Company to fund the expansion of the Company's
products and services through acquisitions of complementary businesses or assets
and for working capital and other general purposes. Pending application of the
net proceeds from the issuance of the Outstanding Notes, the Company has
invested such net proceeds in short-term, interest-bearing, investment grade
securities.

               UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS
 
     The ADI Acquisition was consummated on June 20, 1997 and the DWS/DAMCO
Acquisition was consummated on January 28, 1998. Accordingly, the Unaudited Pro
Forma Combined Statement of Operations for the six months ended October 31, 1997
combines the unaudited operating results for Dailey for the six months ended
October 31, 1997, the unaudited operating results for ADI for the period
beginning on May 1, 1997 and ending on June 20, 1997 and the unaudited operating
results for DWS/DAMCO for the six months ended September 30, 1997. The Unaudited
Pro Forma Combined Statement of Operations for the six months ended October 31,
1997 also reflects the issuance of the Outstanding Notes and the application of
the net proceeds therefrom as if each had occurred on May 1, 1996. The Unaudited
Pro Forma Combined Statement of Operations for the year ended April 30, 1997
combines the audited operating results of Dailey for the year ended April 30,
1997, the unaudited operating results of ADI for the twelve months ended April
30, 1997 and the unaudited combined operating results of DWS/DAMCO for the
twelve months ended March 31, 1997. The Unaudited Pro Forma Combined Balance
Sheet as of October 31, 1997 combines the unaudited balance sheet of Dailey as
of October 31, 1997 and the audited combined balance sheet of DWS/DAMCO as of
September 30, 1997. The unaudited pro forma combined balance sheet as of October
31, 1997 also reflects the issuance of the Outstanding Notes and the application
of the net proceeds therefrom as if such transactions had occurred on October
31, 1997.
 
     The Unaudited Pro Forma Combined Statements of Operations should be read in
conjunction with the notes thereto and the historical financial statements of
Dailey, ADI and DWS/DAMCO, including the notes thereto, included elsewhere
herein.
 
     The pro forma adjustments to give effect to the various events described
above are based upon currently available information and upon certain
assumptions that management believes are reasonable. The ADI Acquisition and the
DWS/DAMCO Acquisition were accounted for by the Company under the purchase
method of accounting, and the assets and liabilities of ADI and DWS/DAMCO have
been recorded at their estimated fair market values at the date of their
respective acquisition. The adjustments included in the Unaudited Pro Forma
Combined Statements of Operations reflect the Company's preliminary
determination of these adjustments based upon available information. There can
be no assurance that the actual adjustments will not vary significantly from the
estimated adjustments reflected in the Unaudited Pro Forma Combined Statements
of Operations.
 
     The unaudited pro forma combined financial information does not purport to
be indicative of the financial position or results of operations that would
actually have occurred if the transactions described had occurred as presented
in such statements or that may be obtained in the future. In addition, future
results may vary significantly from the results reflected in such statements due
to general economic conditions, oil and gas commodity prices, the demand and
prices for contract drilling services and rental tools, the Company's ability to
successfully integrate the operations of ADI and DWS/DAMCO with its current
business and several other factors, many of which are beyond the Company's
control. See "Disclosure Regarding Forward-Looking Statements" and "Risk
Factors".

           NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS
 
PRO FORMA ADJUSTMENTS
 
(A) The unaudited combined statements of operations of DWS/DAMCO for the six
    months ended September 30, 1997 and for the twelve months ended March 31,
    1997 were derived from the unaudited combined statements of operations of
    DWS/DAMCO for the three month periods ended March 31, 1997 and 1996 and the
    audited combined statements of operations of DWS/DAMCO for the nine months
    ended September 30, 1997 and the year ended December 31, 1996. The audited
    combined statements of operations of DWS/DAMCO for the nine months ended
    September 30, 1997 and the year ended December 31, 1996 and the audited
    combined balance sheet as of September 30, 1997 are included elsewhere in
    this Prospectus. Certain reclassifications have been made to conform the
    financial statements of DWS/DAMCO to the pro forma presentation. Such
    reclassifications have no effect on total stockholders' equity or net
    income.
 
(B) To reflect the purchase of the operating assets and liabilities of DWS/DAMCO
    for total consideration of $61 million plus approximately $1 million in
    transaction costs. The acquired assets exclude cash and certain
    non-operating equipment. For purposes of the unaudited pro forma combined
    balance sheet and statement of operations, the purchase price has been
    allocated as follows (in thousands):
 
<TABLE>
<S>                                                           <C>
(1) Historical net book value of DWS/DAMCO..................  $14,986
(2) Adjustment for cash and cash equivalents not acquired...   (2,679)
(3) Fair value adjustment of revenue producing tools and
      inventory.............................................   17,693
(4) Excess of purchase price over the sum of fair value of
      net assets acquired...................................   32,000
                                                              -------
                                                              $62,000
                                                              =======
</TABLE>
 
(C) For purposes of the unaudited pro forma combined balance sheet, the proceeds
    for the DWS/DAMCO Acquisition were assumed to have been provided with
    available cash and, to the extent necessary, additional borrowings under the
    Credit Facility.
 
(D) To record (i) proceeds from the issuance of the Outstanding Notes of $275
    million, net of debt issuance costs of $7,275,000, (ii) the retirement of
    the Old Notes of $114,116,000, net of original issue discount, including a
    premium of 11% of principal amount in consideration for the early
    extinguishment of such debt of $12,650,000, the write-off of related
    unamortized debt issuance costs of $4,050,000, and the payment of accrued
    interest of $2,336,000 and expenses of $200,000, (iii) the repayment of the
    additional borrowings under the Credit Facility and (iv) the impact on
    retained earnings of the resulting extraordinary loss on retirement of debt.
    See "-- Extraordinary Loss on Extinguishment of Debt".
 
(E) The unaudited statement of operations of ADI for the period beginning May 1,
    1997 through June 20, 1997 was derived from the unaudited financial
    statements of ADI for such period. The unaudited statement of operations of
    ADI for the twelve months ended April 30, 1997 was derived from the audited
    statement of operations of ADI for the year ended December 31, 1996 and the
    unaudited statements of operations of ADI for the four month periods ending
    April 30, 1997 and 1996, which are included elsewhere in this Prospectus.
    Certain reclassifications have been made to conform the financial statements
    to the pro forma presentation. Such reclassifications have no effect on
    total stockholders' equity or net income.
 
                                       33

(F) To record additional depreciation and amortization expense associated with
    the purchase price adjustment for DWS/DAMCO assuming a 25-year life for
    goodwill ($1.3 million per year, $640,000 for six months), an average life
    for fixed assets of seven years ($2.5 million per year, $1.3 million for six
    months) and to record additional depreciation and amortization expense
    associated with the purchase price adjustment for ADI through June 20, 1997
    assuming a 20-year life for goodwill ($1.1 million per year, $156,000 for
    the period from May 1, 1997 through June 20, 1997) and an average life for
    fixed assets of eight years ($250,000 per year, $35,000 for the period from
    May 1, 1997 through June 20, 1997).
 
(G) To record additional interest expense on (i) the ADI Acquisition for the
    period from May 1, 1996 through the date of such acquisition, (ii) the
    DWS/DAMCO Acquisition for the period from May 1, 1996 through August 19,
    1997, the date of issuance of the Old Notes and (iii) incremental borrowings
    of $7.5 million from August 20, 1997 to October 31, 1997 beyond the amount
    of the Old Notes, assuming a fixed rate of 9 3/4%. A  1/8% increase in the
    assumed interest rate would have increased annual pro forma interest expense
    by $136,000 for the twelve months ended April 30, 1997 and $33,000 for the
    six-month period ended October 31, 1997.
 
(H) To adjust consolidated income tax expense for the impact of the pro forma
    adjustments and to reflect federal and state income tax expense for
    DWS/DAMCO, which historically did not record such expense (having elected S
    Corporation status). Because the pro forma adjustments result in Dailey
    having net operating losses, and there is no assurance that these net
    operating losses will be benefited for tax purposes before they expire,
    related income tax benefits were not recognized in the pro forma
    adjustments.
 
(I) To remove the gain on the sale of stock not assumed in the ADI Acquisition.
 
(J) To record incremental interest expense related to the issuance of the
    Outstanding Notes and related income tax expense/benefit. The adjusted
    interest amount reflects $275 million of Outstanding Notes outstanding at a
    fixed interest rate of 9 1/2% and amortization of debt issuance costs over
    the 10-year period of the Notes. All other interest expense is eliminated,
    except $223,000 for the twelve months ended April 30, 1997 and $162,000 for
    the six months ended October 31, 1997, on other borrowings, to reflect the
    partial use of proceeds from the issuance of the Outstanding Notes to
    extinguish the Old Notes and other interim financing.
 
EXTRAORDINARY LOSS ON EXTINGUISHMENT OF DEBT
 
     The accompanying unaudited pro forma combined statements of operations for
the twelve months ended April 30, 1997 and the six months ended October 31, 1997
disclose the results of operations and net income (loss) before extraordinary
items. As a result of the issuance of the Outstanding Notes and the use of
proceeds (as discussed above under item (D)), the Company immediately recognized
an extraordinary loss (nonrecurring charge) of approximately $17,784,000 (or
$1.91 per share) on the early retirement of the Old Notes with no related income
tax benefit recognized for financial reporting purposes.

(1) Reorganization costs relate primarily to staff reductions, severance
    settlements and various costs associated with a cost reduction program
    implemented in June 1997 to flatten Dailey's management structure and
    streamline its operations.
 
(2) Non-cash compensation expense relates to accelerated vesting of restricted
    stock that was granted to certain executive officers of Dailey during the
    year ended April 30, 1997 and the six months ended October 31, 1997.
 
(3) The average number of shares outstanding at April 30, 1993 through 1996 has
    been adjusted to give pro forma effect to a reorganization and the issuance
    of an aggregate of 360,000 restricted shares of Class A Common Stock
    contemporaneously with the 1996 IPO. See "Notes to Consolidated Financial
    Statements".
 
(4) Maintenance capital expenditures are primarily comprised of expenditures for
    the replacement of downhole tools lost-in-hole or scrapped and for
    capitalizable repair of assets.
 
(5) Discretionary capital expenditures are primarily comprised of expenditures
    for additions to the downhole equipment, compressors, boosters and other
    property and equipment.
 
(6) For purposes of computing the ratio of earnings to fixed charges, earnings
    are computed as income before income taxes and the cumulative effect of a
    change in accounting principle, plus fixed charges. Fixed charges consist of
    interest expense, whether expensed or capitalized, and amortization of debt
    issuance costs. Pro forma earnings were insufficient to cover pro forma
    fixed charges by $15.6 million for the pro forma year ended April 30, 1997
    and $4.2 million for the pro forma six months ended October 31, 1997.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
RECENT DEVELOPMENTS
 
     Industry Conditions. During 1996 and much of 1997, the oil field service
industry experienced a general improvement in product demand and pricing as
relatively stable and improved oil and or natural gas prices combined with a
strong world economy to increase exploration and development activity worldwide.
This trend benefitted the Company and its results in 1997 and 1996. In recent
months, however, the worldwide price of oil has declined over 40% to as low as
$13 per barrel for spot deliveries and prices for natural gas have weakened
slightly on a year to year basis. These declines have been attributed to, among
other things, an excess supply of oil in the world markets, reduced domestic
demand associated with an unseasonably warm winter and the potential for lower
worldwide demand due to the impact of the economic downturn in Southeast Asia.
As prices for oil have continued to decline, the Company and others in the oil
field services industry have begun to experience a softening in demand for their
products and services, in particular products associated with exploration
activity and oil production. Although the Company believes that demand for its
products and services remains relatively strong and the softening of the market
has mainly impacted demand for products associated with the production of oil
from marginal wells, a prolonged period of low price oil can be expected to
adversely affect the demand throughout the industry, including those products
and services provided by the Company. In such a case, the Company's revenues and
income could be expected to be similarly affected. Although the short term
outlook in the industry remains uncertain, absent a significant downturn in the
U.S. and world economies, the Company believes that market conditions in the
industry should improve over the long term as the demand and supply for oil and
natural gas become more in balance. The timing of such recovery, however, cannot
be predicted with certainty.
 
     IDS Acquisition. The Company acquired the outstanding capital stock of IDS
in March 1998 for approximately $9.4 million in cash and 1,064,000 shares of
Class A Common Stock, plus assumption or repayment of debt of approximately $10
million. As a result of the IDS Acquisition, the Company is now able to provide
a full line of directional drilling services, including logging-while-drilling
services. As result of the IDS Acquisition, the Company estimates that it will
record approximately $20 million in goodwill, representing the excess of the
purchase price over the fair market value of IDS' assets, which will be
amortized over 25 years and result in additional annual amortization expense of
$800,000. Since the goodwill associated with the IDS Acquisition will not be
amortizable for tax purposes, the effective tax rate on Dailey's financial
statements will increase.
 
     Issuance of the Outstanding Notes. The issuance of the Outstanding Notes
further increased the Company's debt levels. On a pro forma basis after giving
effect to the issuance of the Outstanding Notes and the DWS/DAMCO Acquisition,
the Company would have had $277.1 million of total debt outstanding on October
31, 1997, compared to actual total debt of $115.4 million on such date. A
portion of the net proceeds of the issuance of the Outstanding Notes was
utilized to repurchase the Old Notes from the Initial Purchaser. The excess of
the purchase price for the Old Notes over their carrying value will be recorded
as an extraordinary loss on the Company's income statement estimated to be
approximately $17.8 million.
 
     DWS/DAMCO Acquisition. The Company's operations and future results will be
significantly impacted by the DWS/DAMCO Acquisition. Dailey acquired the
operating assets and liabilities of DWS/DAMCO for $61 million in cash and
financed the acquisition with remaining proceeds from its offering of the Old
Notes and borrowings under its Credit Facility. As a result of the DWS/DAMCO
Acquisition, the Company became a leading supplier of electric wireline services
and tubular testing and handling services in the U.S. Gulf of Mexico region and
Nigeria.
 
     The Company expects to experience significant growth as a result of the
DWS/DAMCO Acquisition. On a pro forma basis for the six months ended October 31,
1997, the Company had revenues of $74.4 million compared to $54.6 million for
the same period on a historical basis. The DWS/DAMCO Acquisition also will
expand the Company's presence internationally, primarily in Nigeria.
 
                                       37
<PAGE>   42
 
     The DWS/DAMCO Acquisition was accounted for under the purchase method of
accounting. As a result, the assets and liabilities of DWS/DAMCO were recorded
at their estimated fair market values as of the date of the DWS/DAMCO
Acquisition. The Company currently estimates that goodwill in connection with
the acquisition will be approximately $32.0 million relating to the excess of
the purchase price paid for the assets over their fair market value, which will
be amortized over 25 years and result in approximately $1.3 million in
annualized amortization expense.
 
     ADI Acquisition. The Company's operations have been and will be
significantly impacted by the ADI Acquisition, which was consummated on June 20,
1997. Dailey acquired ADI for $46.4 million, including the repayment of
approximately $16.8 million in debt. As a result of the ADI Acquisition, Dailey
became a leading worldwide provider of air drilling services for underbalanced
drilling applications.
 
     The Company has experienced significant revenue growth as a result of the
ADI Acquisition. On a pro forma basis for the six months ended October 31, 1997,
Dailey had revenues of $17.4 million relating to ADI's operations. The ADI
Acquisition also significantly expanded Dailey's presence internationally,
primarily in Canada.
 
     The ADI Acquisition was accounted for under the purchase method of
accounting. As a result, the operations of ADI following June 20, 1997 are
reflected in Dailey's historical operations and the assets and liabilities of
ADI were recorded at their estimated fair market values as of the date of the
ADI Acquisition. Dailey recorded goodwill of approximately $22.3 million
relating to the excess of the purchase price paid for the assets over their fair
market value, which is being amortized over 20 years and is resulting in
approximately $1.1 million in annualized amortization expense. Since the
goodwill associated with the ADI Acquisition is not amortized for tax purposes,
the effective tax rate shown on Dailey's financial statements has increased
significantly as a result of the ADI Acquisition.
 
     The ADI Acquisition also significantly increased Dailey's debt levels.
Dailey borrowed approximately $45.5 million under the Credit Facility to finance
the acquisition as well as to repay the outstanding debt of ADI, which
significantly increased Dailey's debt over historical levels at that time. The
debt was subsequently repaid with proceeds from the offering of the Old Notes.
 
     June 1997 Reorganization. Following the ADI Acquisition in June 1997,
Dailey implemented a cost-reduction program to flatten its corporate management
structure and streamline its operations (the "Reorganization"). As a result of
such program, Dailey incurred a $2.5 million restructuring charge during the six
months ended October 31, 1997 associated primarily with staff reductions,
severance settlements and various reorganization costs.
 
     1996 Initial Public Offering. Dailey's operations during 1997 reflect the
effects of the 1996 IPO. Dailey's net proceeds of $27.6 million from such
offering were utilized to repay debt to affiliates of Dailey, to acquire certain
business assets and to increase Dailey's inventory of downhole tools.
Utilization of these additional tools increased Dailey's revenues for the year
ended April 30, 1997, primarily during the third and fourth quarters, and is
expected to impact future periods as such tools are utilized in the Company's
business.
 
RESULTS OF OPERATIONS
 
     The Company derives rental income from its fleet of downhole tools and, to
a lesser extent, from downhole tools owned by third parties. The Company
typically charges its customers a daily rental rate for downhole tools, except
for its downhole drilling motors, which are rented at an hourly rate. In
international markets, the Company also often charges its customers a
refurbishment charge, which is included in rental income.
 
     Revenues from sales of products and services consist of directional
drilling services, lost-in-hole charges and sales of its mechanical drilling
jars and, to a lesser extent, from pipeline testing operations acquired in the
ADI Acquisition. Revenues from the acquired DWS/DAMCO operations also will be
reflected in sales of products and services. Revenues from services of the
Company's directional drillers and MWD technicians are generally billed on a per
person/per day basis for the time on assignment at the customer's drill site.
Although the Company considers rentals of its downhole drilling motors and MWD
equipment to be a significant part of its directional drilling services,
revenues from such rentals are currently recorded as rental income for financial
                                       38
<PAGE>   43
 
statement purposes. The Company's lost-in-hole revenues consist of replacement
charges that its customers pay each time a downhole tool is lost-in-hole. The
Company sells mechanical drilling jars in a limited number of international
markets, primarily to state-owned oil and gas companies.
 
     The Company derives underbalanced revenues from rentals of air drilling
equipment used for underbalanced drilling applications, including compressors,
boosters, mist pumps and related equipment, which are typically rented at an
hourly or daily rate. The Company also derives underbalanced revenues by
providing specially-trained personnel, who are typically billed out on a per
person/per day basis, to operate its air drilling equipment.
 
     The operating costs associated with the Company's rentals consist primarily
of expenses associated with depreciation, transportation, maintenance and repair
and related direct overhead. The costs associated with the Company's sales of
products and services consist primarily of the undepreciated portion of the
capitalized cost of its downhole tools sold or lost-in-hole and the salaries and
related costs associated with the Company's directional drillers and MWD
technicians and, to a lesser extent, costs associated with its pipeline testing
operations.
 
     With respect to allowances for bad debts, the Company's policy is to
specifically identify at-risk receivables and reserve for any balances which, in
the opinion of management, are probable or reasonably possible of not being
collected. The Company's bad debt allowance primarily consists of reserves for
receivables from customers that are in bankruptcy, receivables from sales to
agents (based on billings to their customers) that the agent has identified as
potentially uncollectible and receivables from extremely slow-paying domestic
customers. The allowance also contains a reserve for slower-paying, higher-risk
international customers, which have become an increasingly larger percentage of
the Company's customer base in recent years. Similarly, the Company identifies
inventory that, due to changes in demand, is not expected to generate revenue in
the immediate future and establishes a reserve for that inventory.
 
SIX MONTHS ENDED OCTOBER 31, 1997 COMPARED TO THE SIX MONTHS ENDED OCTOBER 31,
1996
 
     Rental Income. Rental income for the six months ended October 31, 1997 was
$31.3 million, an increase of 24% from $25.2 million for the same six months
last year. This increase in revenue was due to the introduction of additional
directional drilling equipment acquired with proceeds from the 1996 IPO and
increased demand for these products and services primarily in the U.S. Gulf
Coast region and the Gulf of Mexico. This increase in demand resulted in a $3.0
million increase in rentals. In addition, revenue from the rental of drilling
jars and related products in the United States increased $1.5 million primarily
due to increased demand as the average domestic rig count in the United States
increased 24% during the period compared to the same period last year.
Internationally, the rental of drilling jars and related products increased $1.7
million, primarily in Indonesia, Australia and Saudi Arabia, as the result of
increased drilling activity.
 
     Sales of Products and Services. Sales of products and services for the six
months ended October 31, 1997 were $11.4 million, an increase of 31% from $8.7
million for the same six months last year. This increase in revenue was
primarily the result of $1.3 million of ADI pipeline testing revenue being
included in operating results since June 20, 1997, an increase in tools
lost-in-hole of $742,000 and increased revenue from directional drilling
services of $1.1 million primarily in the U.S. Gulf Coast region, the Gulf of
Mexico and Venezuela. This increase in revenue was partially offset by a
decrease in sales of mechanical jars of $541,000.
 
     Underbalanced Drilling Services Revenue. Underbalanced drilling services
revenue for the six months ended October 31, 1997 was $11.9 million resulting
from ADI revenue being included in operating results for the first time.
 
     Cost of Rentals. Cost of rentals for the six months ended October 31, 1997
was $21.8 million, an increase of 16% from $18.9 million for the same six months
last year. This increase in cost was due primarily to increased variable costs,
primarily tool repair costs and commissions, associated with increased rental
activity in regions where Dailey had an existing operating and administrative
infrastructure. As a result, gross margins increased from 25% for the six months
ended October 31, 1996 to 30% for the six months ended October 31, 1997 due to
the primarily fixed nature of Dailey's cost base.
 
                                       39
<PAGE>   44
 
     Cost of Products and Services. Cost of products and services for the six
months ended October 31, 1997 was $6.9 million, representing a $2.1 million
increase from the same six months last year, including a $633,000 increase due
to ADI being included in operating results for the first time. The gross profit
margin on sales of products and services for the six months ended October 31,
1997 was 40% compared to 45% for the same six months last year. This decrease in
margin was primarily due to a decrease in higher margin export sales of
mechanical jars combined with increased revenues from lower margin directional
drilling services.
 
     Cost of Underbalanced Drilling Services. Cost of underbalanced drilling
services for the six months ended October 31, 1997 was $7.5 million resulting
from ADI being included in operating results for the first time.
 
     Selling, General and Administrative Expenses. Selling, general and
administrative expenses for the six months ended October 31, 1997 were $10.2
million compared to $6.0 million for the same six months last year. This
increase was primarily the result of increased compensation expense related to
salary increases and incentive compensation programs, costs related to Dailey's
acquisition program, amortization of costs related to the ADI Acquisition and
the inclusion of ADI in operating results for the first time. Cost savings from
the Reorganization partially offset this increase.
 
     Reorganization Costs. Reorganization costs for the six months ended October
31, 1997 were $2.5 million. In June 1997, a cost-reduction program was
implemented to flatten the corporate management structure and streamline
operations. The reorganization costs primarily consist of the cost of staff
reductions, severance settlements and various restructuring costs.
 
     Non-cash Compensation Expense. Non-cash compensation for the six months
ended October 31, 1997 was $539,000, which related to restricted stock that had
been granted to certain executive officers of Dailey in connection with the 1996
IPO and the Company's 1997 Long-Term Incentive Plan (the "1997 Plan").
 
     Interest Income. Interest income for the six months ended October 31, 1997
was $814,000 compared to $207,000 for the same six months last year. This
increase in interest income was the result of interest earned on temporary,
short-term investments utilizing funds from the issuance of the Old Notes.
 
     Interest Expense -- Nonaffiliate. Interest expense for the six months ended
October 31, 1997 was $3.2 million compared to $380,000 for the same six months
last year. This increase was due to the issuance of the Existing Notes.
 
     Income Tax Provision. The provision for income taxes for the six months
ended October 31, 1997 was $1.0 million, a decrease from $1.3 million of expense
for the same six months last year. The decrease in tax expense was due to a
decrease in income before income taxes of $1.3 million partially offset by a
change in the effective tax rate from 37% to 44% due to increased state income
taxes and the non-deductibility of goodwill recorded in connection with the ADI
Acquisition.
 
YEAR ENDED APRIL 30, 1997 COMPARED TO YEAR ENDED APRIL 30, 1996
 
     Rental Income. Rental income for the year ended April 30, 1997 was $49.5
million, an increase of 15% from $43.0 million for the year ended April 30,
1996. This increase was due primarily to increased demand for directional
drilling services and related products in Latin America, the Gulf of Mexico and
the U.S. Gulf Coast region, which resulted in a $5.8 million increase in rentals
from MWD equipment, downhole motors and other directional drilling tools. In
addition, domestic rental income from drilling and fishing jars and slingers
increased $1.3 million which was partially offset by decreased foreign rental
income from drilling and fishing jars and slingers of $892,000.
 
     Sales of Products and Services. Sales of products and services for the year
ended April 30, 1997 were $17.0 million, an increase of 6% from $16.0 million
for the year ended April 30, 1996. This increase was due primarily to increased
demand for directional drilling services and related products in Latin America,
the Gulf of Mexico and the U.S. Gulf Coast region, which resulted in a $1.4
million increase in directional services revenue. In addition, revenues from
license fees related to a proprietary directional drilling method increased by
$300,000. This was partially offset by decreased sales of tools and parts of
$684,000.
 
                                       40
<PAGE>   45
 
     Cost of Rentals. Cost of rentals for the year ended April 30, 1997 was
$37.7 million, an increase of 14% from $33.0 million for the year ended April
30, 1996. This increase was due primarily to the variable costs associated with
an increase in rental activity, such as tool repair costs and third-party tool
charges. As a percentage of rental income, cost of rentals decreased from 77% in
fiscal 1996 to 76% in fiscal 1997, which reflects the fixed nature of the cost
base.
 
     Cost of Products and Services. Cost of products and services for the year
ended April 30, 1997 was $8.9 million, an increase of 12% from $7.9 million for
the year ended April 30, 1996. The increase was due primarily to higher
personnel costs associated with an increase in directional drilling services in
the Gulf of Mexico, the U.S. Gulf Coast region and Venezuela. The gross profit
margin on sales of products and services for fiscal 1997 was 48% compared to 50%
for fiscal 1996. This decrease in gross profit margin was due to a decrease in
higher margin export sales of mechanical jars.
 
     Selling, General and Administrative Expenses. For the year ended April 30,
1997, selling, general and administrative expenses, including a $2.8 million
non-cash compensation expense, were $14.7 million, an increase of 22% from the
$12.1 million for the year ended April 30, 1996. The non-cash compensation
expense was the result of non-cash stock awards granted to certain officers
pursuant to the 1996 Key Employee Stock Plan. Exclusive of these non-cash
changes, selling, general and administrative expenses were $11.9 million, a 2%
decrease from fiscal 1996.
 
     Research and Development Expenses. Research and development expenses for
the year ended April 30, 1997, were $850,000, compared to $728,000 for the year
ended April 30, 1996, which reflects a relatively constant level of research and
development activity.
 
     Interest Income. Interest income for the year ended April 30, 1997 was
$640,000, an increase of $536,000 from the year ended April 30, 1996. This was
the result of interest earned on short-term investments utilizing net proceeds
from the 1996 IPO.
 
     Interest Expense -- Nonaffiliates. Interest expense to nonaffiliates for
the year ended April 30, 1997 was $671,000, a decrease of 15% from $785,000 for
the year ended April 30, 1996. This decrease was primarily the result of
scheduled payments of principal and interest on bank debt.
 
     Interest Expense -- Affiliate. Interest expense to affiliate for the year
ended April 30, 1997 was $162,000, a 11% decrease from $182,000 for the year
ended April 30, 1996. This decrease was primarily the result of the repayment of
a term loan to an affiliate with proceeds from the 1996 IPO, partially offset by
interest paid on a promissory note to an affiliate that was issued in connection
with a dividend on June 27, 1996 and repaid with proceeds from the 1996 IPO.
 
     Foreign Exchange (Gain) Loss. Foreign exchange loss for the year ended
April 30, 1997 was $19,000 compared to a loss of $239,000 for the year ended
April 30, 1996. This decrease was due primarily to favorable fluctuations in the
British pound exchange rate relative to the U.S. dollar.
 
     Income Tax Expense. Income tax expense for the year ended April 30, 1997
was $1.5 million, an increase of 6% from $1.4 million for the year ended April
30, 1996. This increase was primarily the result of an increase in the effective
tax rate to 38% for fiscal 1997 from 35% for fiscal 1996 due to the full
utilization of the state net operating loss carryforwards in fiscal 1996.
 
YEAR ENDED APRIL 30, 1996 COMPARED TO THE YEAR ENDED APRIL 30, 1995
 
     Rental Income. Rental income for the year ended April 30, 1996 was $43.0
million, an increase of 17% from $36.7 million for the year ended April 30,
1995. This increase was due primarily to increased demand for Dailey's
directional drilling services and related products in the Gulf of Mexico, the
U.S. Gulf Coast region and Venezuela, which resulted in a $4.2 million increase
in rentals from MWD equipment, downhole motors and other directional drilling
tools. During fiscal 1996, Dailey purchased MWD equipment for use in Venezuela.
Dailey also experienced increased demand for its directional drilling services
in the Gulf of Mexico and the U.S. Gulf Coast region due to escalating gas
prices and a corresponding increase in drilling activity. In addition, rental
income from Dailey's drilling jars and slingers increased $1.4 million due
primarily to
 
                                       41
<PAGE>   46
 
increased demand in Latin America and to a slight increase in pricing worldwide.
Also in fiscal 1996, Dailey increased its distribution of fishing jars in the
U.S. Gulf Coast region and expanded distribution of fishing jars into the North
Sea, which resulted in an increase in rental income of $1.0 million.
 
     Sales of Products and Services. Sales of products and services for the year
ended April 30, 1996 were $16.0 million, an increase of 31% from $12.2 million
for the year ended April 30, 1995. This increase was due primarily to an
increase in export sales of mechanical drilling jars of approximately $1.6
million and to an increase in lost-in-hole revenues of $1.2 million. The
increase in lost-in-hole revenues was consistent with increased rental activity
during the year. The increase also was attributable to increased demand for
Dailey's directional drilling services in the Gulf of Mexico, the U.S. Gulf
Coast region and Venezuela.
 
     Cost of Rentals. Cost of rentals for the year ended April 30, 1996 was
$33.0 million, an increase of 11% from $29.7 million for the year ended April
30, 1995. This increase was due primarily to the variable costs associated with
an increase in rental activity, such as tool repair costs, agent commissions and
third-party tool charges. The increase also was attributed to an increase in
import duties and fees of $709,000 associated with the importation of downhole
tools to Venezuela. Dailey expenses import duties and fees as incurred instead
of capitalizing them as part of the cost of the tool. As a percentage of rental
income, cost of rentals decreased from 81% in fiscal 1995 to 77% in fiscal 1996,
which reflects the fixed nature of Dailey's cost base.
 
     Cost of Products and Services. Cost of products and services for the year
ended April 30, 1996 was $7.9 million, an increase of 15% from $6.9 million for
the year ended April 30, 1995. This increase was due primarily to higher
personnel costs associated with an increase in directional drilling services in
the Gulf of Mexico, the U.S. Gulf Coast region and Venezuela. The increase also
was attributable to the write-off of the net book value of products lost-in-hole
and the cost of drilling jars sold during the year.
 
     Selling, General and Administrative Expenses. Selling, general and
administrative expenses were $12.1 million for the year ended April 30, 1996, an
increase of 26% from $9.6 million for the year ended April 30, 1995. This
increase was due primarily to an increase in personnel costs associated with
bonuses and raises paid during the year as well as additional personnel, an
increase in travel and business development costs associated with higher levels
of international business and an increase in legal expenses associated with
litigation involving Dailey's enforcement of its intellectual property.
 
     Research and Development Expenses. Research and development expenses for
the year ended April 30, 1996 were $728,000, a decrease of 6% from $775,000 for
the year ended April 30, 1995, as the level of Dailey's research and development
activity remained relatively constant between the two years.
 
     Interest Expense -- Nonaffiliates. Interest expense to nonaffiliates for
the year ended April 30, 1996 was $785,000, a decrease of 7% from $841,000 for
the year ended April 30, 1995. The decrease was due primarily to the repayment
throughout fiscal 1996 of an aggregate of $1.3 million in principal on Dailey's
bank debt, which was partially offset by advances in the second half of fiscal
1996 of $1.3 million against the revolving line of credit associated with
Dailey's bank debt.
 
     Interest Expense -- Affiliate. Interest expense to affiliate for the year
ended April 30, 1996 was $182,000, a decrease of 17% from $220,000 for the year
ended April 30, 1995. The decrease was due to the repayment of $660,000 of
principal during the year.
 
     Foreign Exchange (Gain) Loss. Foreign exchange losses of $239,000 in fiscal
1996 compared to gains of $90,000 for the year ended April 30, 1995 were due
primarily to unfavorable exchange fluctuations during fiscal 1996 with the
British pound and the Dutch guilder.
 
     Other (Income) Expense, net. Other expense for the year ended April 30,
1996 was $39,000 compared to $190,000 for the year ended April 30, 1995. This
decrease was due primarily to the write-off of $60,000 of unusable fixed assets
in fiscal 1995.
 
     Income Tax Expense. Provision for income taxes for the year ended April 30,
1996 was $1.4 million compared to $838,000 for the year ended April 30, 1995.
The increase was due primarily to an increase in income in countries in which
Dailey was subject to income or withholding taxes, which resulted in the
effective tax rate decreasing from 104% to 35% from fiscal 1995 to fiscal 1996.
In fiscal 1996, Dailey recorded
                                       42
<PAGE>   47
 
a deferred tax asset related to net operating loss carryforwards, which resulted
in a decrease in the effective tax rate. This decrease was predominantly offset
by a gain for tax purposes related to the dissolution of a real estate
partnership, which resulted in an increase in the effective tax rate.
 
INFLATION AND FOREIGN EXCHANGE
 
     Inflation has not had a significant impact on Dailey's comparative results
of operations. For the year ended April 30, 1997, transactions conducted in
United States dollars accounted for approximately 74% of the Company's total
revenues. The Company believes that the percentage of its total revenues
relating to transactions conducted in foreign currencies will increase due to
continued expansion of the Company's international operations and the DWS/DAMCO
Acquisition. The Company currently does not engage in hedging transactions to
protect itself against foreign currency fluctuations, but rather seeks to
protect itself from fluctuations in foreign currencies by accelerating
conversion of such currencies into United States dollars and by continual
evaluation of the Company's level of operations in such markets.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     Working Capital. Cash provided by operating activities was $845,000 during
the six months ended October 31, 1997. Additional sources of cash included net
proceeds from the issuance of debt of $159.6 million, $1.5 million from
revenue-producing tools lost-in-hole, abandoned and sold, $704,000 from stock
options exercised and $607,000 of proceeds from the sale of property and
equipment. Principal uses of cash for the six months ended October 31, 1997 were
to fund acquisitions (net of cash acquired) of $46.2 million, to repay bank debt
of $52.9 million, to purchase treasury stock of $813,000, to pay financing costs
relating to the issuance of the Old Notes of $4.1 million and to fund capital
expenditures of $14.8 million. During the past several years, working capital
requirements have been funded through cash generated from operations, credit
facilities and asset sales.
 
     Credit Facility. The Company currently has no outstanding borrowings under
the Credit Facility. Borrowings under the Credit Facility currently are limited
to the lesser of $15 million or an amount calculated utilizing a loan formula
based upon the level of eligible accounts receivable, which was $11.3 million as
of December 31, 1997. The Credit Facility is collateralized by substantially all
of the Company's and its domestic subsidiaries' assets. It contains restrictive
covenants and events of defaults customary in loan transactions of that type.
The Company currently is renegotiating the terms and conditions of the Credit
Facility following the issuance of the Outstanding Notes. The Company is
prohibited from borrowing funds under the Credit Facility until such
renegotiation is complete.
 
     Capital Expenditures. Capital expenditures of approximately $14.8 million
were made during the six months ended October 31, 1997. Of this amount, $10.4
million were invested in downhole tools, primarily MWD and other directional
equipment, hydraulic drilling jars, hydraulic fishing jars and related
inventory. Capital expenditures for downhole tools and other equipment during
the next twelve months, assuming consummation of this Offering, are expected to
be approximately $34.9 million. The Company believes it will have available
resources from the net proceeds from the issuance of the Outstanding Notes,
internally generated cash flow and availability under the Credit Facility to
fund operations for at least the next twelve months. In addition, as part of its
business strategy, the Company is continuing to analyze potential acquisitions
of complementary businesses and assets. The Company expects to fund any future
acquisitions utilizing a portion of its availability under the Credit Facility
and a portion of the net proceeds from the issuance of the Outstanding Notes;
however, depending upon the size of any future acquisition, the Company may need
additional financing to fund such acquisitions.
 
     Future Acquisitions. As consolidation of the oil and gas services industry
continues in response to increased demand for companies offering a broad range
of services, the Company intends to continue expanding its products and services
through strategic acquisitions. The Company continuously evaluates potential
acquisition candidates in the drilling, completion and workover segments of the
industry, including companies providing directional drilling, underbalanced
drilling, fishing and enhanced recovery services, as well as companies supplying
specialized downhole tools and other equipment to the oil and gas industry. In
 
                                       43
<PAGE>   48
 
connection with any future acquisition, the Company may be required to incur
substantial indebtedness to finance such acquisition and may also issue equity
securities or convertible securities. The Company is reviewing several
attractive acquisition opportunities that, if consummated, would allow it to
continue to expand the breadth and geographic scope of the products and services
it offers as well as create additional cross-marketing opportunities for
internal growth.
 
     Old Notes. On August 19, 1997, Dailey issued the Old Notes in a private
placement at a discount of 0.785%. The net proceeds from the issuance of the Old
Notes of approximately $109.6 million were used to repay $45.5 million then
outstanding under Dailey's credit facility incurred primarily in connection with
the ADI Acquisition. A portion of the proceeds also were utilized to fund
planned capital expenditures. The remaining proceeds were utilized to finance a
substantial portion of the DWS/DAMCO Acquisition. The Old Notes bore interest at
a rate of 9 3/4%, payable semi-annually on February 15 and August 15 of each
year, commencing February 15, 1998, and matured August 15, 2007 but were
redeemable at the option of the Company on or after August 15, 2002. The Company
repurchased all of the Old Notes from the Initial Purchaser utilizing a portion
of the net proceeds from the issuance of the Outstanding Notes.
 
NEW ACCOUNTING PRONOUNCEMENTS
 
     In February 1997, the Financial Accounting Standards Board (the "FASB")
issued Statement of Financial Accounting Standards ("SFAS") No. 128, Earnings
Per Share. This statement establishes new standards for computing and presenting
earnings per share requiring the presentation of "basic" and "diluted" earnings
per share as compared to "primary" and "fully diluted" earnings per share. The
Company is required to adopt SFAS No. 128 in the first quarter of calendar 1998.
Earlier adoption is not permitted and restatement of all prior period earnings
per share data is required. The Company believes that the "diluted" disclosure
required under SFAS No. 128 will not differ materially from historical "primary"
earnings per share amounts for the 1996 and 1997 periods presented.
 
     In June 1997, the FASB issued SFAS No. 131, Disclosures about Segments of
an Enterprise and Related Information, which is effective for years beginning
after December 15, 1997. SFAS No. 131 establishes standards for the way that
public business enterprises report information about operating segments in
annual financial statements and requires that those enterprises report selected
information about operating segments in interim financial reports. It also
establishes standards for related disclosures about products and services,
geographic areas and major customers. SFAS No. 131 is effective for financial
statements for fiscal years beginning after December 15, 1997, and, therefore,
the Company will adopt the new requirements retroactively in 1998. Management
has not completed its review of SFAS No. 131, but does not anticipate that the
adoption of this statement will have a significant effect on the Company's
reported operations.
 
IMPACT OF YEAR 2000
 
     Some of the Company's computer programs were written using two digits
rather than four to define the applicable year. As a result, those computer
programs have time-sensitive software that recognizes a date using "00" as the
year 1900 rather than the year 2000. If not corrected, this could cause 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 currently is in the process of converting its information
systems as part of a total business knowledge management process conversion,
which will include all operating systems, for a total estimated cost of
approximately $3.5 million. The system conversion is estimated to be completed
no later than December 31, 1998; however, it is possible that certain efforts
will be delayed into 1999. The greatest Year 2000 compliance risk is that system
conversion will be delayed beyond the anticipated completion date and the severe
shortage of qualified information systems personnel, both internally and
externally, could affect compliance efforts. The Company believes that with
conversions to new software, the Year 2000 issue will not pose significant
operational problems for its computer systems.
 
     The estimated cost and the anticipated date of system implementation are
based on management's best estimates; however, there can be no assurance that
these estimates will be achieved, and actual results could differ materially
from those anticipated.

                            BUSINESS AND PROPERTIES
 
GENERAL
 
     The Company is an integrated provider of specialty services and
technologically-advanced downhole tools to the oil and gas industry on a
worldwide basis. The Company's services include (i) directional drilling
services, (ii) underbalanced drilling services, (iii) electric wireline and
tubing conveyed perforating services, (iv) tubular testing and handling services
and (v) downhole tool rental. The Company has recently expanded its operations
significantly through strategic acquisitions and internal growth. In March 1998,
the Company acquired IDS, a specialized provider of directional drilling
services, and in January 1998, the Company acquired the operating assets and
liabilities of DWS/DAMCO, specialized providers of electric wireline and tubular
services in the U.S. Gulf of Mexico region and, to a lesser extent, in Nigeria.
The Company believes the DWS/DAMCO Acquisition provides it with significant
operational benefits, including geographic expansion and cross-marketing
opportunities.
 
BUSINESS STRATEGY
 
     The Company's strategy is to expand and diversify the geographic
distribution and range of products and services it provides to the drilling,
completion and workover segments of the upstream oil and gas industry through
internal growth and acquisitions. The Company expects to continue to effect
internal growth primarily by cross marketing its product and service lines and
expanding its recently acquired operations to additional locations within the
Company's worldwide infrastructure.
 
     In addition, as consolidation of the oil and gas services industry
continues in response to increased demand for companies offering a broad range
of services, the Company intends to continue expanding its products and services
through strategic acquisitions. The Company continuously evaluates potential
acquisition candidates in the drilling, workover and completion segments of the
oilfield services industry, including companies providing directional drilling,
underbalanced drilling, fishing and enhanced recovery services, as well as
companies supplying specialized downhole tools and other equipment to the oil
and gas industry. The Company is reviewing several acquisition opportunities
that, if consummated, would allow it to continue to expand the breadth and
geographic scope of the products and services it offers as well as create
additional cross-marketing opportunities for internal growth.
 
RECENT DEVELOPMENTS
 
     Consistent with its strategy, since April 1997, Dailey has completed five
acquisitions, all of which expand Dailey's scope of operations and geographic
presence and add long-term earnings capacity.
 
     - Integrated Services Limited. In March 1998, the Company acquired (the
       outstanding capital stock of IDS, a directional drilling service company,
       for $9.4 million in cash and 1,064,000 shares of Class A Common Stock,
       plus assumption or repayment of debt of approximately $10.0 million.
 
     - Four Corners Air Service. In February 1998, the Company acquired the
       operating assets of Four Corners Air Service, Inc., an air drilling
       service company based in Farmington, New Mexico, for approximately $3.4
       million.
 
     - DWS/DAMCO. In January 1998, Dailey acquired of the operating assets and
       liabilities of DWS/DAMCO for $61 million in cash, subject to adjustment
       based on levels of working capital.
 
     - ADI. In June 1997, Dailey acquired ADI for $46.4 million, including the
       repayment of approximately $16.8 million of indebtedness.
 
     - Great Southern Drilling. In April 1997, Dailey acquired the assets of
       Great Southern Drilling Services, Inc., a directional drilling company
       operating in the U.S. mid-continent region, for approximately $1.6
       million and a contingent cash payment of up to $740,000.

DRILLING SERVICES
 
  Directional Drilling Services
 
     Directional drilling services involve assisting oil and gas operators in
the controlled drilling of a wellbore to a prescribed bottomhole location.
Directional drilling can be used to develop a field with multiple wells drilled
from the same offshore platform or, in environmentally sensitive areas, from
fewer surface facilities than conventional drilling would require. In addition,
drilling horizontally through a formation characterized by multiple vertical
fractures can result in substantial reductions in drilling costs and improved
well productivity because fewer wells are required compared to a vertical
development program. Recent developments in multilateral technology, which
allows two or more wells to be drilled from the same vertical wellbore, have
further enhanced well productivity and development efficiency.
 
     Based on published industry sources, the number of oil and gas wells
drilled in the United States using directional and horizontal technology
increased 120% from 2,110 in 1990 to 4,649 in 1997, and, as a percentage of
total oil and gas wells drilled in the United States, wells drilled using
directional and horizontal technology increased from 7% in 1990 to 17% in 1997.
This growth has been driven primarily by the substantial cost savings,
improvements to drilling efficiency and enhancements to reservoir production
that such techniques can provide to operators as well as increased offshore
drilling activity.
 
     Dailey began offering directional drilling services in 1984, primarily
along the Texas and Louisiana Gulf Coast, and has since expanded both its
directional drilling technical capabilities and the geographic areas in which
its services are regularly offered. In fiscal 1995, Dailey began providing its
drilling services in international markets by expanding into Venezuela.
 
     The Company provides skilled personnel to manage the drilling of
directional wells. The directional drilling services offered by the Company
consist of well planning, on-site supervisory services to maximize drilling
efficiency, MWD services and related equipment rentals, downhole motor rentals
and post-well analysis. The Company also derives revenue from its directional
drilling services by renting MWD units, thrusters, downhole motors and
nonmagnetic stabilizers. Through the acquisition of IDS, the Company acquired
key technologies, including a resistivity tool for LWD that is compatible with
Dailey's MWD fleet. The Company believes that the addition of LWD technology to
Dailey's MWD fleet will enable it to offer more fully integrated directional
drilling systems in the Gulf of Mexico and Venezuela and will allow the Company
to expand the geographic markets in which it provides such services.
 
     The skill, experience and reputation of a service company's directional
drillers are the primary competitive factors in the directional drilling
services market. Because of this, the competition among directional drilling
service companies to employ the most reputable, qualified and experienced
directional drilling personnel is intense. In addition, the scope of services
offered as well as price are important competitive factors. The Company believes
that the quality and experience of its directional drillers provide it with a
competitive advantage and also believes that it is able to recruit and retain
highly-qualified directional drillers because it has a reputation in the
industry for stability and quality, offers competitive compensation and provides
a reliable, experienced support staff. As of January 31, 1998, Dailey employed
44 directional drillers.
 
     The guidance instruments used by directional drillers typically consist of
either wireline steering tools or more advanced MWD units. MWD units provide a
directional driller with extensive and advanced information to guide the
drillstring, including inclination, azimuth, tool face and temperature plus
magnetic tool face updates in steering or rotary drilling modes. MWD units also
can provide gamma ray logging information. Reliable MWD units currently are
available for third-party purchase worldwide from only a few independent
suppliers. The Company began purchasing MWD units from its current supplier and
offering such systems and services to its customers in fiscal 1994. The
Company's MWD units compete favorably with respect to reliability and
performance with MWD units developed in-house by more fully-integrated service
companies and other reliable MWD units currently available for third-party
purchase. Directional drilling typically is conducted using a downhole drilling
motor attached to the drill bit and powered by the circulation of drilling
fluids from the surface. The Company manufactures and uses its own downhole
motor.
 
                                       46
<PAGE>   51
 
  Underbalanced Drilling Services
 
     Underbalanced drilling involves maintaining the pressure in a well at less
than that of the surrounding formation using air, nitrogen, mist, foam or
lightweight drilling fluids as the circulation medium instead of mud. As a
result of the ADI Acquisition, the Company is a worldwide leader in providing
air drilling services, which are used in underbalanced drilling applications,
and, since the acquisition, has developed internally the ability to provide
other services utilized in underbalanced drilling applications. The Company
provides underbalanced drilling equipment packages consisting of compressors,
boosters, mist pumps and related equipment along with specially trained
personnel to operate the equipment. Underbalanced drilling techniques can lead
to substantial increases in rates of penetration and drill bit life resulting in
substantially less time and cost for a drilling program and can reduce
substantially the risks of formation damage.
 
     Horizontal and directional wells frequently are drilled using underbalanced
drilling technology to reduce the risk of formation damage and improve the flow
of hydrocarbons in low pressure or depleted reservoirs. In addition, the Company
believes that the geothermal industry will be a major source of growth in demand
for underbalanced drilling services, especially in South America, Central
America and the Pacific Rim. The use of underbalanced drilling in geothermal
wells often avoids the problem of losing drilling fluids in porous geothermal
formations or, in certain cases, causing the formation to be plugged.
 
     A typical package of equipment used in an underbalanced drilling job
consists of two compressors, a booster and a mist pump. Compressors are used to
force air into the borehole. Depending on the pressure and air volume
requirements, additional compressors may be needed. Boosters are used to
increase the pressure of air exiting a compressor and can increase the air
pressure up to five-fold. Mist pumps are used to mix and distribute water, soaps
and other fluids in underbalanced drilling applications.
 
ELECTRIC WIRELINE AND TUBING CONVEYED PERFORATING SERVICES
 
     As a result of the acquisition of DWS/DAMCO, the Company is a leading
provider of electric wireline and TCP services in the U.S. Gulf of Mexico region
and Nigeria. The Company's electric wireline services are utilized in both the
exploration and production phases of an oil and gas well and include pipe
recovery, cased hole logging, electric wireline perforating services and other
cased hole services such as installation of bridge plugs, packers, retainers,
pressure control equipment and thru-tubing bridge plugs.
 
     TCP services involve the use of tubing string to lower and retrieve
perforating charges from the wellbore. The Company believes operating synergies
exist between its electric wireline and TCP services and its downhole tool
rental business as such products and services can be effectively marketed in a
single package. The Company intends to expand its electric wireline and TCP
services by marketing these services through its established distribution
networks for its other products and services.
 
TUBULAR TESTING AND HANDLING SERVICES
 
     As a result of the acquisition of DWS/DAMCO, the Company is a leading
provider of tubular testing and handling services to the onshore and offshore
oil and gas industry in the U.S. Gulf of Mexico region. The Company's tubular
testing services consist of hydrostatic and gas pressure testing services that
detect leaks and flaws in tubulars as they are run into the wellbore. The
Company believes operators prefer to incur testing charges to avoid incurring
costly downtime and the expense of pulling a defective tubular string.
 
     The Company's tubular handling services include assembling production pipe
and tubing, dual completion strings, premium threaded connectors and ultra-high
torque tubulars. The Company believes that mistakes in torquing tubulars can be
costly in terms of downtime and damaged equipment, and therefore, operators rely
on experienced tubular companies for handling services.
 
DOWNHOLE TOOLS
 
     The Company currently offers an array of technologically-advanced downhole
tools, which it selectively markets in every major oil and gas exploration and
production region in the world. Dailey began renting downhole tools in 1945 and
introduced the first drilling jar to the oil and gas industry in 1965. The
Company is
                                       47
<PAGE>   52
 
currently the leading supplier of drilling jars to the rental tool market
worldwide. In addition to drilling jars, the Company rents other proprietary
downhole tools including hydraulic fishing jars, coiled tubing jars, drilling
shock absorbers, drilling thrusters and drilling slingers.
 
     The Company's line of drilling jars and related products include mechanical
and hydraulic drilling jars and jar slingers. A drilling jar is an impact tool
that is placed in the lower section of a drillstring as part of the bottomhole
assembly. Activated from the surface, the drilling jar delivers a sharp,
powerful impact to free the drillstring should it become lodged in the hole. The
potential risks of the drillstring becoming stuck in the hole include
interruption of the drilling process, loss of drillstring components and loss of
the well. Drilling jars must be capable of reliably delivering frequent and
consistent impacts to the drillstring, sometimes over a period of many days. As
a result, reliability and consistent performance and service by qualified
personnel are key criteria in a customer's selection of drilling jars.
 
     Drilling jars and jar slingers generally are used in drilling applications
where there is significant risk of, or cost associated with, the bottomhole
assembly of the drillstring becoming stuck in the wellbore. As the risk or
potential cost of a stuck drillstring increases, the likelihood that the
operator of the well will employ a drilling jar typically increases. Drilling
applications where drilling jars are used regularly include high-cost wells,
wells drilled using directional, horizontal or underbalanced techniques, deeper
wells, and wells penetrating unstable geologic formations that increase the risk
of well bore collapse. Drilling jars generally are considered essential
components in most directional drilling bottomhole assemblies. The Company
believes that the proprietary designs of its drilling jars deliver superior
performance over competing jars for longer periods of time in their intended
operating environments and are compatible with virtually any drilling condition
a customer may encounter.
 
     In addition to drilling jars, the Company rents other proprietary downhole
tools including hydraulic fishing jars, coiled tubing jars, drilling shock
absorbers, drilling thrusters and drilling slingers. The Company also derives
revenues from the sale of mechanical drilling jars and from downhole tools that
are lost-in-hole by the operator.
 
OTHER SERVICES
 
     The Company is one of the largest fully-integrated pipeline testing
companies in Canada and is the leading provider of hydrostatic testing services
to major Canadian pipeline construction companies that lack the capability to
perform such testing in-house. The Company believes that the planned addition of
new pipeline capacity in Canada over the next few years, as well as increased
environmental concerns relating to existing pipelines, should result in
increased demand for the Company's pipeline testing services.
 
MARKETING AND DISTRIBUTION
 
     The Company markets its products and services primarily to major oil
companies, independent oil and gas exploration companies, drilling contractors
and drilling services consultants. In international markets, state-owned oil and
gas companies also are a significant customer group. Domestic marketing of the
Company's products and services is conducted by the Company's direct sales
force. International marketing of the Company's products and services is
conducted through the Company's direct sales force or through independent
international agents and also through cooperative marketing arrangements with
local companies. Dailey traditionally has marketed its array of proprietary
downhole tools directly to the end-user through its direct sales force and
agents, rather than rely on third-party distribution of its products and
subcontracting of its services. The Company believes this strategy results in
higher profit margins. Additionally, this direct interaction with the end-user
assists the Company in identifying demand for new and improved products and
better enables it to design and develop such products in a timely manner.
 
INTERNATIONAL OPERATIONS
 
     Dailey's international operations (including Canada) accounted for
approximately 39%, 42%, 39% and 51% of total revenues for fiscal 1995, 1996 and
1997 and the six months ended October 31, 1997, respectively. As of January 31,
1998, Dailey had operations in approximately 39 foreign countries. See Note 14
of the Notes

to Consolidated Financial Statements of Dailey contained elsewhere in this
Prospectus for additional information regarding foreign and domestic revenues.
 
     The Company's international agents are responsible for international
marketing of the Company's downhole tools in certain of its markets.
International agents also perform maintenance of the Company's downhole tools in
their custody at their own facilities. International marketing and distribution
is organized into four major regions: Europe/West Africa, the Middle East,
Southeast Asia and Latin America. Each region is further divided into multiple
and sometimes overlapping territories, generally based on political boundaries.
Regional supervisors are assigned by the Company to oversee international
operations, particularly with respect to proper maintenance and redressing of
tools and to provide sales support and technical assistance to customers.
 
     The Company's international operations are subject to special
considerations inherent in doing business outside the United States, including
political instability, war, civil disturbances and governmental activities,
which may limit or disrupt markets, restrict the movement of funds or result in
the deprivation of contract rights or the taking of property without fair
compensation. Government-owned petroleum companies located in some of the
countries in which the Company operates have adopted, or are subject to,
policies that mandate that preference be given to companies that are
majority-owned by local nationals. In addition, the Company conducts a portion
of its international operations in currencies other than the United States
dollar and, as such, is subject to certain risks associated with exchange rate
fluctuations. Although the Company maintains political risk insurance to protect
itself from such risks, such insurance may be insufficient to protect the
Company in all circumstances, and any failure to do so could have a material
adverse effect on the Company's results of operations and financial condition.
See "Management's Discussion and Analysis of Financial Condition and Results of
Operations".
 
MANUFACTURING AND MAINTENANCE
 
     The manufacturing processes generally required to produce the Company's
downhole tools are machining, fabrication, assembly of components manufactured
by the Company or outside suppliers, and quality control testing. The Company
attempts to outsource those manufacturing processes that can be performed more
efficiently and cost effectively by outside third parties. The Company believes
that its manufacturing capabilities and arrangements are sufficient in order to
meet the demand and timing needs of the Company's customers for the next twelve
months. Machining of larger components and spare parts, including the most
complex components, is done by the Company at its manufacturing plant in Conroe,
Texas. Fabrication, assembly and packaging of the Company's wireline units,
compression equipment and tubular handling equipment are performed at the
Company's Houma, Louisiana, Casper, Wyoming and Edmonton, Canada locations.
Through the IDS Acquisition, the Company acquired IDS' manufacturing operations
in Scotland relating to various directional drilling equipment. The
manufacturing processes performed in-house by the Company require a ready supply
of high-quality, special alloy steel and other raw materials. The Company
purchases its raw materials from various vendors, none of which supplied a
majority of Dailey's supply of such materials during fiscal 1997. Consistent
with the recent upturn in the demand for steel and other raw materials used in
the oil and gas industry, the Company has experienced longer lead times for
delivery of raw materials, primarily steel, which requires the Company to
predict further in advance its needs for such materials. Although the Company
typically places orders for its steel at least three months in advance and
usually stores with a third party a reserve supply of steel adequate to cover
the Company's demand for steel for at least one month, any prolonged disruption
in steel supply could affect the Company's ability to meet production schedules
and commitments, which could have a material adverse effect on the Company's
financial condition and results of operations.
 
     Maintenance of the Company's downhole tools is conducted in the United
States at six of the Company's facilities, each of which is specially equipped
for that purpose. In the United Kingdom, Colombia and Venezuela, maintenance is
conducted by Company personnel, and elsewhere by the Company's international
agents who are subject to periodic quality control inspection and supervision by
Company personnel.

INTELLECTUAL PROPERTY
 
     The Company believes that the proprietary aspects of many of its products
and services provide it with certain competitive advantages. In particular, the
Company believes that the trademarks and servicemarks protecting the Dailey name
in domestic and international markets are of primary importance. The Company
relies on a combination of patents, trade secrets, trademarks and servicemarks
and copyrights to protect its proprietary technologies and intellectual
properties. Patents protect features of the Dailey Hydraulic Jar and Dailey
Hydraulic Fishing Jar, as well as other of the Company's products and services.
In additional, pursuant to the DWS/DAMCO Acquisition and IDS Acquisition, the
Company acquired additional key patents relating to its TCP services and
directional drilling services. Although the Company does not consider its
business to be wholly dependent on any single patent or trademark, the
unexpected loss of patent protection for the Dailey Hydraulic Jar or Dailey
Hydraulic Fishing Jar could have a material adverse effect on the Company.
 
OPERATING RISKS AND INSURANCE
 
     The operations of the Company's customers are subject to hazards inherent
in the oil and gas industry, such as blowouts, explosions, craterings, fires and
oil spills, that can cause personal injury or loss of life, damage to or
destruction of property, equipment, the environment and marine life, and
suspension of operations. Claims for loss of oil and gas production and damage
to formations can occur in the workover process. Additionally, the Company often
is required to indemnify major customers pursuant to master service agreements.
If a serious accident were to occur where the Company's downhole tools are used
or its directional drilling services are being provided, the Company could be
named as a defendant in lawsuits asserting potentially large claims.
 
     As protection against operating hazards, the Company maintains insurance
coverage that it believes to be customary in the industry against these hazards
and, whenever possible, obtains agreements from customers providing for
indemnification against liability. The Company maintains general liability
insurance to cover its buildings, equipment and other property as well as
worker's compensation, maritime employer, auto, crime and political risk
insurance. The Company also is insured under an umbrella liability policy. Most
of the Company's policies provide for coverage on a per-occurrence basis, rather
than a claim basis. The Company's policies generally exclude coverage for losses
and liabilities relating to environmental damage or pollution, breach of
contract or fraud or deceptive practices. The Company does not maintain
professional liability insurance.
 
     Historically the Company's insurance coverage has greatly exceeded the
amount of its claims and management believes that the Company's insurance
coverage is adequate for its present operations. However, a successful liability
claim for which the Company is underinsured or uninsured could have a material
adverse effect on the Company.
 
COMPETITION
 
     All of the Company's products and services are offered in
highly-competitive markets in which many of the Company's competitors are
divisions or subsidiaries of larger, better capitalized corporations. The
Company believes that its leading competitors are fully-integrated service
companies, but it also competes on a regional basis with numerous smaller,
independent companies that offer only relatively limited lines of products and
services compared to fully-integrated competitors.
 
     Management expects competition and customer price pressures to continue for
the foreseeable future with respect to its specialty services and downhole
tools.
 
EMPLOYEES
 
     At January 31, 1998, the Company had 716 employees, approximately 75% of
whom were located in the United States. The Company has never experienced a work
stoppage and considers its employee relations to be excellent. The Company has
no collective bargaining agreements.

REGULATION
 
     Various federal, state and local laws and regulations covering the release
of materials into the environment, or otherwise relating to the protection of
the public health and the environment, affect the Company's and its customers'
domestic operations, expenses and costs. The trend in environmental regulation
has been to place more restrictions and limitations on activities that may
impact the environment, such as emissions of pollutants, generation and disposal
of wastes, and use and handling of chemical substances. Increasingly strict
environmental restrictions and limitations, as well as the obligation to
remediate existing contamination, have resulted in increased operating costs for
the Company and other similar businesses throughout the United States. The costs
of compliance with environmental laws and regulations may continue to increase,
both for the Company and its customers. In this regard, the Resource
Conservation and Recovery Act ("RCRA"), a federal statute governing the disposal
of solid and hazardous wastes, includes a statutory exemption that allows oil
and gas exploration and production wastes to be classified as nonhazardous
waste. A similar exemption is contained in many of the state counterparts to
RCRA. If oil and gas exploration and production wastes were required to be
managed and disposed of as hazardous waste, either as a result of a change in
RCRA or the imposition of more stringent state regulations, domestic oil and gas
producers, including many of the Company's customers, could be required to incur
substantial obligations with respect to such wastes. Because of the potential
impact on the Company's customers, any regulatory changes that impose additional
restrictions or requirements on the disposal of oil and gas wastes could
adversely affect demand for the Company's products and services. In addition,
the Company is subject to laws and regulations concerning occupational health
and safety. The Company's international operations also are subject to
international laws respecting environmental and worker safety matters in the
countries in which they operate. The Company believes that it is in substantial
compliance with the requirements of environmental and occupational health and
safety laws and regulations, but inasmuch as such laws and regulations are
frequently changed, the Company is unable to predict the ultimate impact of such
laws and regulations on the Company's business. Any violation of such laws could
subject the Company to fines, penalties or other liabilities.
 
     Capital expenditures for property, plant and equipment for environmental
control facilities during fiscal 1997 were not material. Based on the Company's
experience to date, the Company currently does not anticipate any material
adverse effect on its results of operations or financial condition as a result
of future compliance with existing environmental laws and regulations
controlling the discharge of materials into the environment. However, future
events, such as changes in existing laws and regulations or their
interpretation, more vigorous enforcement policies of regulatory agencies, or
stricter or different interpretations of existing laws and regulations, may
require additional expenditures by the Company, which may be material.

charged for audit services performed by the auditors, and evaluates the
Company's system of internal accounting controls. The Compensation Committee
recommends to the Board the compensation to be paid to the Company's directors,
executive officers and key employees and administers the compensation plans for
the Company's executive officers. The Executive Committee acts on behalf of the
Board between regularly scheduled meetings of the Board.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
     Prior to September 1996, compensation levels were determined by the
Company's Board of Directors, each of the members of which are officers of the
Company. Following the 1996 IPO, the Compensation Committee has determined
compensation levels and other benefits payable to the Company's executive
officers, other than compensation pursuant to employment agreements entered into
prior to the 1996 IPO.
 
COMPENSATION OF DIRECTORS
 
     Employee directors of the Company do not receive any additional
compensation for their services as a director of the Company. The Company pays
an annual retainer of $15,000 to each non-employee director. In addition, each
non-employee director receives $1,000 for each Board of Directors meeting
attended and $750 for each committee meeting attended. The Company also pays
reasonable out-of-pocket expenses incurred by non-employee directors to attend

EMPLOYMENT AGREEMENTS
 
     Each of Messrs. Lawrence, Farr, Sutton and Tighe (collectively, the
"Executive Officers") has entered into an employment agreement (collectively,
the "Executive Employment Agreements") with the Company. Each of the Executive
Employment Agreements has an initial term through December 31, 2000, except the
Executive Employment Agreement with Mr. Lawrence, which has an initial term
through December 31, 1999. The Executive Employment Agreements provide for a
minimum annual salary during the term of the Executive Employment Agreements of
approximately $100,000, $336,000, $273,000 and $216,000 for Messrs. Lawrence,
Farr, Sutton and Tighe, respectively. The Executive Employment Agreements also
provide for certain automobile allowances, employee benefits, vacation and
reimbursement of expenses.
 
     The Executive Employment Agreements may be terminated by the Company with
or without cause (as hereinafter defined) or by the Executive Officer at any
time for any reason.
 
     If the Company terminates the Executive Employment Agreement for any reason
other than for "cause" and such termination is not within one year of a change
in control (as defined in the Executive Employment Agreements), the Company is
required to pay to the Executive Officer an amount equal to the greater of his
total base salary for the remainder of the employment period (as defined in the
Executive Employment Agreement) or one month of base salary for each full year
of service completed with the Company as of the date of termination (or, in the
case of Mr. Lawrence, three months of his base salary, if greater) and, with the
exception of Mr. Lawrence, (i) to pay an amount equal to the Executive Officer's
most recent annual bonus and (ii) to cause the Executive Officer to become fully
vested in any stock options and stock grants held by him. If the Company
terminates the Executive Employment Agreement with Mr. Lawrence for any reason
other than for "cause" and such termination occurs within one year of a change
in control, or if Mr. Lawrence terminates the Agreement for good cause (as
defined in the Executive Employment Agreement) and such termination occurs
within one year of a change in control, the Company is required to pay to Mr.
Lawrence an amount equal to the greater of (i) his total base salary for the
remainder of the employment period; (ii) two times the greater of (a) his
annualized base salary in effect upon the occurrence of the change in control or
(b) his annualized base salary in effect on the date notice of termination is
received; or (iii) one month of base salary for each full year of service
completed with the Company as of the date of termination. If the Company
terminates the Executive Employment Agreement of Messrs. Farr, Sutton or Tighe
for any reason other than for "cause" and such termination occurs within one
year of a change in control, or if the Executive Officer terminates the
agreement for good cause (as defined in the Executive Employment Agreement) and
such termination occurs within one year of a change of control, the Company is
required (i) to pay the Executive Officer 2.99 times his annualized base salary
in effect upon the occurrence of the change in control, (ii) to pay the
Executive Officer an amount equal to 2.99 times the greater of his most recent
annual bonus or a target bonus of $243,000, $50,000 and $50,000 for Messrs.
Farr, Sutton and Tighe, respectively, and (iii) to cause the Executive Officer
to become fully vested in any stock options and stock grants held by him.
 
EMPLOYEE STOCK PLANS
 
     The Company has established its 1996 Key Employee Stock Plan (the "1996
Plan"), pursuant to which incentive and non-qualified options to purchase shares
of Class A Common Stock and awards of restricted shares of Class A Common Stock
are available for future grants. Under the 1996 Plan, options to purchase Class
A Common Stock and restricted stock awards up to an aggregate of 900,000 shares
of Class A Common Stock may be granted by the Compensation Committee. As of the
date of this Prospectus, the Company less than 1,000 shares available for grant
under such plan. In addition, the Company has adopted the 1997 Plan pursuant to
which incentive and non-qualified options, restricted shares, stock appreciation
rights and other performance-based awards may be granted to key employees of the
Company. The 1997 Plan initially has 720,000 shares of Class A Common Stock
available for issuance. The number of shares of Class A Common Stock available
for issuance under the 1997 Plan is subject to adjustment as of January 1 of
each year if the total number of shares of Class A Common Stock issued and
outstanding exceeds the number of shares of Class A Common Stock outstanding as
of January 1 of the preceding year. In such case, the number of shares available
for issuance will be increased by an amount such that the total number of shares
available for issuance under the 1997 Plan equals 7.85% of the total number of
shares of Class A Common Stock
                                       57
<PAGE>   62
 
outstanding, not including shares issued pursuant to the 1997 Plan. To date, the
Company has granted under the 1997 Plan options to purchase 150,000 shares of
Class A Common Stock and 236,000 shares of restricted Class A Common Stock.
 
401(k) PLAN
 
     The Company's domestic employees are eligible to participate in a defined
contribution retirement plan that complies with Section 401(k) of the Internal
Revenue Code (the "Code") and that was adopted by Lawrence prior to the 1996 IPO
for its employees and the employees of its subsidiaries. Pursuant to the plan,
the Company provides matching contributions equal to 50% of the employee's
contribution, subject to a maximum matching contribution equal to 3% of the
employee's compensation.
 
                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
PRINCIPAL STOCKHOLDER
 
     Prior to the 1996 IPO, Dailey had funded certain of its working capital
requirements through advances from Lawrence, which had been evidenced by a note
to Lawrence. Dailey repaid the full amount of principal of such note with $1.6
million of the net proceeds from the 1996 IPO. In addition, on June 27, 1996,
Dailey declared and paid a dividend in the form of a $10.0 million promissory
note to Dailey's sole stockholder, a subsidiary of Lawrence. On August 13, 1996,
such stockholder contributed $5.0 million of the outstanding principal amount of
such note to the capital of Dailey. The remaining $5.0 million principal plus
accrued interest was repaid utilizing a portion of the net proceeds from the
1996 IPO.
 
     Lease Agreements. The Company maintains executive offices in a building
located in Conroe, Texas and occupies four adjacent manufacturing and
maintenance research and development, and storage facilities, all of which are
owned by Lawrence International, Inc. During fiscal 1995, 1996 and 1997, the
Company incurred rent expense of $1,244,000, $1,306,000 and $915,000,
respectively, relating to such properties. Prior to completion of the 1996 IPO,
Dailey entered into a new lease agreement with Lawrence International, Inc.
relating to the executive office building and a separate lease agreement
relating to the adjacent facilities. The rental rates under these new lease
agreements were determined by Dailey and Lawrence International, Inc. based upon
a survey of rental rates prepared by an independent firm. Based upon this
survey, the Company believes that the rental rates and other terms under these
lease agreements are comparable to those that would be obtained in an
arm's-length transaction with an independent third party.
 
     The Office Lease Agreement is for a five-year term effective as of May
1996, and covers all of the 64,368 square feet of office space in the Conroe
building, as well as the use of access roads and an adjacent outdoor parking
lot. Rent is payable monthly at the rate of $48,276 per month for the first two
years of the lease, $51,226 per month for the third year, $52,781 per month for
the fourth year and $54,390 per month for the fifth year.
 
     The Service Center Lease Agreement is for a five-year term effective as of
May 1996. This lease covers the combined square feet of the district facility
building, 31,316 square feet; the manufacturing building, 31,373 square feet;
the open storage building, 17,000 square feet and the separator building, 1,530
square feet. The use of access roads and immediately surrounding grounds is also
included. Rent is $28,000 per month for all four buildings in the aggregate.
 
     Relationship Agreement. Under the terms of a relationship agreement between
the Company and Lawrence (the "Relationship Agreement"), the Company has agreed
to provide to Lawrence and its affiliates, upon their request and on an
as-available basis, various administrative and management services including
cash management, accounting, tax, data processing, human resources and legal
services. Lawrence pays for such services at rates calculated to recover the
Company's reasonable costs of providing such services. The Relationship
Agreement also provides that Lawrence will render to the Company technical
consulting services when requested by the Company. In return, the Company will
pay Lawrence approximately $250,000 per year for the term of the Relationship
Agreement. The Relationship Agreement commenced upon the closing of the
 
                                       58
<PAGE>   63
 
1996 IPO and terminates on April 30, 1999. In addition, under the Relationship
Agreement, Lawrence and the Company have agreed to reimburse each other for the
costs of certain insurance policies purchased by one party on behalf of the
other. As of April 30, 1997, Lawrence owed the Company approximately $68,000,
for products and services rendered pursuant to the Relationship Agreement.
 
     Tax Allocation Agreement. For taxable periods ending on or before the
closing of the 1996 IPO, the Company was included in the consolidated federal
income tax returns filed by Lawrence as the common parent for itself, its
subsidiaries and affiliated companies. The Company is jointly and severally
liable for federal income tax imposed on the Lawrence consolidated group while
the Company is a member. The Tax Allocation Agreement imposes an indemnity on
Lawrence in favor of the Company for any federal income tax relating to members
of the Lawrence consolidated group other than the Company and its subsidiaries.
 
     Registration Rights Agreement. Pursuant to the terms of a registration
rights agreement with Lawrence (the "Lawrence Registration Rights Agreement"),
upon the request of Lawrence (or certain assignees) for a period of ten years
(beginning in 1996), the Company has agreed to register, on up to two occasions,
the sale of a minimum of 500,000 shares and up to all 5,000,000 shares of Class
B Common Stock beneficially owned by Lawrence that Lawrence (or such assignees)
requests to be registered under the Securities Act and applicable state
securities laws. The Company will become obligated to register the sale of the
Class B Common Stock on one additional occasion if Mr. Lawrence dies during the
term of the Lawrence Registration Rights Agreement and Lawrence previously has
exhausted its two demand registrations. The Company also is obligated to offer
Lawrence and certain assignees the right to include shares of the Class B Common
Stock owned by it in certain registration statements filed by the Company. The
Company is obligated to pay all expenses incidental to such registrations,
excluding fees of counsel to Lawrence, underwriters' discounts and commissions,
and transfer fees.
 
OTHER
 
     In January 1997, the Company loaned Mr. Farr $250,000 pursuant to a
five-year promissory note. Interest accrues at the prime rate and is payable
monthly by Mr. Farr. The note is secured by a pledge of 36,000 shares of Class A
Common Stock held by Mr. Farr.
 
     Air Drilling Services, Inc. leases its Casper, Wyoming property from Melodi
Lane Investments, L.L.C. ("Melodi Lane"), a limited liability company in which
Mr. Chaman Malhotra, an employee of the Company, is a member. The lease is for a
term of ten years, expiring in June 2006, and provides for monthly rental
payments of $4,250, subject to adjustment beginning July 2001. The lease also
provides Air Drilling Services, Inc. with a right to purchase the property at
its fair market value on or before May 31, 2001. Air Drilling Services, Inc.
also leases certain equipment from Melodi Lane for $7,400 per month. Such
equipment lease expires in June 2001 and provides for an option to purchase
based on amortization schedule providing for a purchase price of $0 at the end
of the term.
 
     Certain subsidiaries of ADI guarantee a loan of Mr. Malhotra to Southern
Pacific Thrift and Loan Assn., which had a principal balance of $87,987 at April
30, 1997. Such loan relates to a condominium held by Mr. Malhotra and his wife
as nominee for such subsidiaries.
 
     A subsidiary of ADI also leases real property in Nisku, Alberta from
Malhotra Enterprises Ltd. ("Malhotra Enterprises"), a Canadian corporation in
which both Mr. Malhotra and Mr. Tommy Ramsay, an employee of the Company, are
shareholders. Lease payments for this real property aggregate CDN $8,470 per
month. The lease expires in December 2005. A subsidiary of ADI also leases
certain equipment from Malhotra Enterprises pursuant to a lease expiring in
October 1997. This equipment lease requires monthly payments of $21,822 and
contains an option to purchase the equipment for $20,000 plus the monthly rental
for all unexpired months.
 
     In 1986, Dailey purchased the design, patents and rights to certain
hydraulic tools and entered into a royalty agreement with the seller that
expires in 1999 and 2003 as to the covered hydraulic drilling and fishing jars,
respectively. Royalty agreements were executed between Dailey and the royalty
owner in fiscal 1993 and fiscal 1994 on newly issued methods and apparatus
patents related to a double-acting drilling accelerator and
 
                                       59

improvements to hydraulic drilling jars. In March 1994, the royalty agreements
were amended to cap royalties at 5% of annual net rental revenues derived from
the hydraulic drilling and fishing jars and double-acting drilling accelerators
through December 1999, with the royalty percentage decreasing to 4% from January
2000 to expiration of the applicable patents. Upon expiration of the patents, no
royalties will be required. The amended agreement also revised the 1% royalty
paid on net lost-in-hole revenue for the original hydraulic drilling jar patent
to the 2% provided in subsequent royalty agreements. In consideration for the
execution of the amendment to the royalty agreement, Dailey agreed to pay the
owner of the royalty $250,000 in royalties. The $250,000, net of imputed
interest, was recorded as an expense at April 30, 1994, and subsequent to that
date, Dailey arranged for the payment of this amount through a note payable. For
the years ended April 30, 1997, 1996 and 1995, the accompanying consolidated
statements of operations include royalty expense of $879,000, $843,000 and
$826,000, respectively, excluding the $250,000 related to the amended royalty
agreement. The owner of the royalty was an officer of Dailey until October 1994.
 
     During fiscal 1996, the Company's Chairman of the Board repaid
approximately $87,000 relating to a loan made by Dailey in June 1994. Such loan
was evidenced by a promissory note in the principal amount of $75,000, accrued
interest at a rate of 8.0% and was repayable on demand. During the year ended
April 30, 1996, Dailey paid a salary of $206,406, including bonuses, to Melissa
Lawrence, the daughter of the Chairman of the Board. This employment arrangement
was terminated on April 30, 1996, and the Company does not anticipate paying any
salaries or bonuses to Ms. Lawrence in the future. In addition, during the
fiscal years ended April 30, 1995, 1996 and 1997, Dailey purchased office
supplies totaling $136,588, $114,041 and $24,521, respectively, from a company
owned and controlled by the Chairman's wife.
 
     In August 1997, John W. Sinders, Jr., and Executive Vice President of
Jefferies, accepted his appointment as a non-voting advisory director of the
Board of Directors of the Company. Although Mr. Sinders does not currently
receive cash compensation for his position as a non-voting advisory director, he
has been granted options to purchase 10,000 shares of Common Stock and the
Company may offer him additional compensation in the future. Jefferies has
provided investment banking services to the Company in the past, including
serving as lead underwriter in the 1996 IPO and as the initial purchaser in the
sale and issuance of the Old Notes, for which Jefferies has received usual and
customary fees. Jefferies sold the Old Notes to the Company contemporaneously
with the closing of the issuance of the Outstanding Notes at an aggregate price
of 111% of their principal amount, plus accrued and unpaid interest up to, but
not including, the date of payment. Jefferies acquired the Old Notes in
privately negotiated transactions with qualified institutional buyers and
institutional accredited investors. Pursuant to a letter agreement between the
Company and Jefferies, Jefferies has acted and will continue to act as a
financial advisor to the Company in connection with the acquisition of, merger
or other combination with certain potential acquisition targets. If the Company
completes a transaction with any such target, the Company will pay Jefferies
certain usual and customary fees for such services. Except for usual and
customary fees paid in connection with the DWS/DAMCO Acquisition and $1.0
million in connection with other financial advisory services, the Company has
not paid Jefferies and is not obligated to pay Jefferies any compensation for
services rendered under this agreement to otherwise to date. Jefferies may
provide additional investment banking and financial advisory services to the
Company in the future.

                       DESCRIPTION OF THE EXCHANGE NOTES
GENERAL
 
     The Exchange Notes will be issued under an indenture (the "Indenture")
dated as of February 13, 1998, among the Company, the Subsidiary Guarantors and
U.S. Trust Company of Texas, N.A., as trustee (the "Trustee"). Upon the issuance
of the Exchange Notes or the effectiveness of the Exchange Offer Registration
Statement, the Indenture will be subject to and governed by the Trust Indenture
Act of 1939, as amended (the "Trust Indenture Act"). The following summaries of
certain provisions of the Indenture do not purport to be complete and are
subject to, and are qualified in their entirety by reference to, all of the
provisions of the Indenture, including the definition of certain terms contained
therein and those terms that are made a part of the Indenture by reference to
the Trust Indenture Act. Copies of the Indenture and Registration Rights
Agreement have been filed as an exhibit to the Registration Statement of which
this Prospectus is a part. Capitalized terms not otherwise defined below or
elsewhere in this Prospectus have the meanings given to them in the Indenture.
The definitions of certain capitalized terms used in the summary are set forth
below under "-- Certain Definitions".
 
     The Indenture provides for the issuance of up to $275 million of
Outstanding Notes and an equal aggregate principal amount of Exchange Notes that
may be issued in exchange for Outstanding Notes pursuant to the Exchange Offer.
The Indenture also provides the Company the flexibility of issuing additional
Notes in the future in an unlimited amount; however, any issuance of such
additional Notes would be subject to the covenant described in the first
paragraph under "-- Certain Covenants -- Limitation on Incurrence of Additional
Indebtedness". The Outstanding Notes, the Exchange Notes and any additional
Notes are collectively referred to as the "Notes" in this "Description of the
Exchange Notes".
 
PRINCIPAL, MATURITY AND INTEREST
 
     The Exchange Notes will be unsecured senior general obligations of the
Company, will mature on February 15, 2008 (the "Maturity Date") and will be
limited in aggregate principal amount to $275,000,000. The Exchange Notes will
be issued in denominations of $1,000 and integral multiples thereof. Subject to
certain exceptions, the Exchange Notes will be initially sold to Qualified
Institutional Buyers in book-entry form, registered in the name of a nominee of
the Depository Trust Company ("DTC"), the transfers of which will be effected
through records maintained by DTC and its participants in registered
certificated form. See "-- Book Entry; Delivery and Form".
 
     The Exchange Notes will accrue interest at the rate per annum shown on the
cover page of this Prospectus from the date of issuance of the Exchange Notes,
or from the most recent interest payment date to which interest has been paid or
for which interest has been duly provided. Interest on the Outstanding Notes
that are tendered in exchange for the Exchange Notes that has accrued from
February 13, 1998, the date of issuance of the Outstanding Notes, through the
Exchange Date will be payable on or before August 15, 1998. Outstanding Notes
that are accepted for exchange will cease to accrue interest on and after the
date on which interest on the Exchange Notes will begin to accrue. Accrued and
unpaid interest will be payable semi-annually on February 15 and August 15 of
each year, commencing August 15, 1998. Interest will be paid to the Person in
whose name the Exchange Note is registered at the close of business on the
February 1 or August 1 next preceding such interest payment date. Interest will
be computed on the basis of a 360-day year of twelve 30-day months. The Exchange
Notes will be payable both as to principal and interest at the office or agency
of the Company maintained for such purpose within the City and State of New York
and in the case of Exchange Notes not in book-entry form, interest may be paid,
at the option of the Company, by check mailed to the holders of the Notes
("Holders") at their respective addresses set forth in the register of Holders.
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. Any
Outstanding Notes that remain outstanding after the completion of the Exchange
Offer, together with the Exchange Notes issued in connection with the Exchange
Offer, will be treated as a single class of securities under the Indenture.

RANKING
 
     The Exchange Notes will be unsecured, senior general obligations of the
Company, ranking pari passu in right of payment with all other Indebtedness of
the Company that is not subordinated by its terms to other Indebtedness of the
Company and senior to all Indebtedness of the Company that by its terms is so
subordinated.
 
     The holders of secured Indebtedness of the Company (including Indebtedness
under the Company's Credit Facility, which is secured by substantially all
property, equipment, inventory, intellectual property and receivables of the
Company and the Subsidiary Guarantors), will have claims with respect to the
assets constituting collateral for such Indebtedness that are prior to claims of
Holders. In the event of a default on the Notes or a bankruptcy, liquidation or
reorganization of the Company, such assets will be available to satisfy
obligations with respect to the Indebtedness secured thereby before any payment
therefrom could be made on the Notes. To the extent that the value of such
collateral is not sufficient to satisfy the Indebtedness secured thereby,
amounts remaining outstanding on such Indebtedness would be entitled to share
with the Notes and their claims with respect to any other assets of the Company.
 
     The Exchange Notes will be effectively subordinated to claims of creditors
and preferred stockholders of the Company's Subsidiaries (other than the Company
and any Subsidiary Guarantor) and the claims of secured creditors of the
Subsidiary Guarantors. Claims of creditors and preferred stockholders of such
subsidiaries (other than the Company and any Subsidiary Guarantor), including
trade creditors, tort claimants, secured creditors, taxing authorities and
creditors holding guarantees, will generally have priority as to assets of such
subsidiaries over the claims and equity interests of the Company and, thereby
indirectly, the holders of the Indebtedness of the Company, including the Notes.
At October 31, 1997, on a pro forma basis after giving effect to the DWS/DAMCO
Acquisition, the issuance of the Outstanding Notes and the application of the
net proceeds therefrom, the Notes and Subsidiary Guarantees would have been
effectively subordinated to $2.1 million of secured Indebtedness (excluding
letters of credit) of the Subsidiary Guarantors.
 
REDEMPTION AND REPURCHASE
 
     Optional Redemption. The Exchange Notes will be redeemable at the option of
the Company, at any time or in part from time to time, on and after February 15,
2003 at the following redemption prices (expressed as percentages of the
principal amount) if redeemed during the twelve-month period commencing on
February 15 of the year set forth below, plus, in each case, accrued interest
thereon to the date of redemption:

</TABLE>
 
     In the event of a redemption of less than all of the Notes, the Notes will
be selected for redemption by the Trustee in multiples of $1,000 pro rata, by
lot or by any other method that the Trustee considers fair and appropriate, and,
if the Exchange Notes are listed on any securities exchange, by a method that
complies with the requirements of such exchange. Notice of redemption will be
mailed at least 30 days but not more than 60 days before the redemption date to
each Holder of Notes to be redeemed at such Holder's registered address. On and
after the redemption date, interest will cease to accrue on Notes or portions
thereof called for redemption (unless the Company shall default in the payment
of the redemption price or accrued interest).
 
     In addition, at any time or from time to time on or prior to February 15,
2001, the Company may redeem up to 35% of the aggregate principal amount of the
Notes originally issued at 109 1/2% of the principal amount thereof, together
with accrued and unpaid interest, if any, to the date of redemption with the Net
Proceeds of one or more Public Equity Offerings; provided that, immediately
after giving effect to such redemption, at
 
                                       63
<PAGE>   68
 
least 65% of the aggregate principal amount of the Notes originally issued
remains outstanding immediately after such redemption and that such redemption
occurs within 60 days following the closing of such Public Equity Offering.
 
     Offers to Purchase. As described below, (i) upon the occurrence of a Change
of Control, the Company will be obligated to make an offer to purchase all
outstanding Notes at a purchase price in cash equal to 101% of the principal
amount thereof, together with accrued and unpaid interest, if any, to the date
of purchase and (ii) upon certain sales or other dispositions of assets, the
Company may be obligated to make offers to purchase Notes with a portion of the
Net Available Proceeds of such sales or other dispositions at a purchase price
in cash equal to 100% of the principal amount thereof, together with accrued and
unpaid interest, if any, to the date of purchase. See "-- Change of Control" and
"-- Certain Covenants -- Limitation on Assets Sales".
 
CHANGE OF CONTROL
 
     Upon the occurrence of a Change of Control, the Company will be obligated
to make an offer to purchase all of the then-outstanding Notes (a "Change of
Control Offer") and shall purchase, on a Business Day (the "Change of Control
Purchase Date"), not more than 60 nor less than 30 days following the Change of
Control, all or any part of the then-outstanding Notes validly tendered pursuant
to such Change of Control Offer, at a purchase price (the "Change of Control
Purchase Price") in cash equal to 101% of the principal amount thereof, plus
accrued and unpaid interest, if any, to the Change of Control Purchase Date. The
Change of Control Offer is required to remain open for at least 20 Business Days
and until the close of business on the fifth Business Day prior to the Change of
Control Purchase Date.
 
     In order to effect such Change of Control Offer, the Company shall, not
later than 30 days after the Change of Control, mail to the Trustee and to each
Holder of the Notes notice of the Change of Control Offer, which notice shall
govern the terms of the Change of Control Offer and shall state, among other
things, the procedures that Holders of the Notes must follow to accept the
Change of Control Offer.
 
     The Company, to the extent applicable and if required by law, will comply
with Sections 13 and 14 of the Exchange Act and the provisions of Rule 14e-1 of
the Exchange Act and any other tender offer rules under the Exchange Act and any
other federal and state securities laws, rules and regulations which may then be
applicable to any offer by the Company to purchase the Notes pursuant to the
Change of Control covenant.
 
     Should a Change of Control occur and a substantial amount of the Notes be
presented for purchase, there can be no assurance that the Company would have
sufficient financial resources to enable it to purchase such Notes. In the event
the Company is required to purchase outstanding Notes pursuant to a Change of
Control Offer, the Company expects that it would seek third-party financing to
the extent it does not have available funds to meet its purchase obligations.
However, there can be no assurance that the Company would be able to obtain such
financing. The Credit Facility may provide that certain change of control events
with respect to the Company would constitute an event of default thereunder and
permit the agent or lenders thereunder to terminate the commitment of the
lenders under the Credit Facility and declare all amounts outstanding thereunder
to be due and payable. Any future credit agreements or other arrangements
relating to Senior Indebtedness to which the Company or any of its Subsidiaries
becomes a party may contain similar restrictions and provisions. In the event
that a Change of Control occurs at a time when the Company is prohibited from
purchasing the Notes, the Company could seek the consent of its lenders to
purchase the Notes or could attempt to repay or refinance the borrowings that
contain such prohibition. If the Company does not obtain such a consent or repay
such borrowings, the Company will remain prohibited from purchasing the Notes.
 
     The Indenture provides that a default in the payment of the Change of
Control Purchase Price when due would constitute an Event of Default under the
Indenture.
 
     The Change of Control provisions of the Indenture, as well as the
restrictions in the Indenture on the ability of the Company and its Subsidiaries
to incur additional Indebtedness, to grant Liens on their property, to make
Restricted Payments and to make Asset Sales, may make more difficult or
discourage a takeover of
 
                                       64
<PAGE>   69
 
the Company, whether favored or opposed by current management of the Company.
Consummation of any such transaction in certain circumstances may require
redemption or repurchase of the Notes, and there can be no assurance that the
Company or the acquiring party will have sufficient financial resources to
effect such redemption or repurchase. Such restrictions and the restrictions on
transactions with Related Persons may, in certain circumstances, make more
difficult or discourage any leveraged buyout of the Company or any of its
Subsidiaries by the management of the Company. Except as described above with
respect to a Change of Control, the Indenture does not contain provisions that
permit the Holders of the Notes to require that the Company repurchase or redeem
the Notes in the event of a takeover, a recapitalization or similar
restructuring.
 
     The Company will not be required to make a Change of Control Offer
following a Change of Control if a third party makes the Change of Control Offer
in the manner, at the times and otherwise in compliance with the requirements
set forth in the Indenture applicable to a Change of Control Offer made by the
Company and purchases all Notes validly tendered and not withdrawn under such
Change of Control.
 
     One of the events that constitutes a Change of Control under the Indenture
is a sale, conveyance, transfer or lease of all or substantially all of the
assets of the Company and the Subsidiaries, taken as a whole to any Person other
than the Company or a Subsidiary Guarantor that is a Wholly-Owned Subsidiary.
The Indenture will be governed by New York law, and there is no established
quantitative definition under New York law of "substantially all" of the assets
of a corporation. Accordingly, if the Company were to engage in a transaction in
which it disposed of less than all of its assets, a question or interpretation
could arise as to whether such disposition was of "substantially all" of its
assets and whether the Company was required to make a Change of Control Offer.
 
     The provisions of the Indenture may not afford Holders protection in the
event of a highly leveraged transaction, reorganization, restructuring, merger
or similar transaction affecting the Company that may adversely affect Holders,
if such transaction is not the type of transaction included within the
definition of Change of Control. A transaction involving the management of the
Company or its Affiliates, or a transaction involving a recapitalization of the
Company, will result in a Change of Control only if it is the type of
transaction specified in such definition.
 
SUBSIDIARY GUARANTEES
 
     The Subsidiary Guarantors, which consist of all of the Company's
Subsidiaries as of the Issue Date other than any Exempt Foreign Subsidiary, as
designated by the Company, will unconditionally guarantee, jointly and
severally, to each Holder and the Trustee, the full and prompt performance of
the Company's obligations under the Indenture and the Notes, including the
payment of principal of, premium, if any, and interest on the Notes. In addition
to the initial Subsidiary Guarantors, the Company will cause each Person (other
than an Unrestricted Subsidiary and any Exempt Foreign Subsidiary) that shall
become a Material Subsidiary after the Issue Date to execute and deliver a
supplement to the Indenture pursuant to which such Person will guarantee the
payment of the Notes on the same terms and conditions as the Subsidiary
Guarantees by the Subsidiary Guarantors. As described below under "-- Certain
Covenants -- Limitation on Incurrence of Additional Indebtedness", no Subsidiary
that is not already a Subsidiary Guarantor shall incur any Indebtedness with
respect to Indebtedness of the Company or another Subsidiary unless such
Subsidiary becomes a guarantor of the Notes. As a result, claims of creditors
against Unrestricted Subsidiaries, Exempt Foreign Subsidiaries and Subsidiaries
that have not delivered Guarantees, including their trade creditors and tort
claimants, will effectively have priority to the property and earnings of such
Subsidiaries over claims of creditors of the Company, including Holders.
 
     The Exempt Foreign Subsidiaries as of February 6, 1998 accounted for 17% of
the Company's revenues for the six months ended October 31, 1997. In addition,
such Exempt Foreign Subsidiaries represented approximately 8% of the Company's
total assets as of October 31, 1997.
 
     The obligations of each Subsidiary Guarantor are limited to the maximum
amount as will, after giving effect to all other contingent and fixed
liabilities (including, but not limited to, Guarantor Senior Indebtedness of
such Subsidiary Guarantor) of such Subsidiary Guarantor and after giving effect
to any collections from or
                                       65
<PAGE>   70
 
payments made by or on behalf of any other Subsidiary Guarantor in respect of
the obligations of such other Subsidiary Guarantor under its Subsidiary
Guarantee or pursuant to its contribution obligations under the Indenture,
result in the obligations of such Subsidiary Guarantor under its Subsidiary
Guarantee not constituting a fraudulent conveyance or fraudulent transfer under
federal or state law. Each Subsidiary Guarantor that makes a payment or
distribution under a Subsidiary Guarantee shall be entitled to a contribution
from each other Subsidiary Guarantor in a pro rata amount based on the Adjusted
Net Assets of each Subsidiary Guarantor.
 
     Each Subsidiary Guarantor may consolidate with or merge into or sell or
otherwise dispose of all or substantially all of its properties and assets to
the Company or another Subsidiary Guarantor without limitation, except to the
extent any such transaction is subject to the "Merger, Consolidation or Sale of
Substantially All Assets" covenant of the Indenture. Each Subsidiary Guarantor
may consolidate with or merge into or sell or otherwise dispose of all or
substantially all of its properties and assets to a Person other than the
Company or another Subsidiary Guarantor that is a Wholly-Owned Subsidiary
(whether or not affiliated with the Subsidiary Guarantor that is a Wholly-Owned
Subsidiary), provided that (i) if the surviving Person is not the Subsidiary
Guarantor, the surviving Person agrees to assume such Subsidiary Guarantor's
Subsidiary Guarantee and all its obligations pursuant to the Indenture (except
to the extent the following paragraph would result in the release of such
Subsidiary Guarantor) and (ii) such transaction does not (a) violate any of the
covenants described below under "-- Certain Covenants" or (b) result in a
Default or Event of Default immediately thereafter that is continuing.
 
     Upon the sale or other disposition (by merger or otherwise) of a Subsidiary
Guarantor or all or substantially all of its properties and assets pursuant to a
transaction that is otherwise in compliance with the Indenture (including as
described in the foregoing paragraph), such Subsidiary Guarantor shall be deemed
released from its Subsidiary Guarantee and the related obligations set forth in
the Indenture; provided, however, that any such termination shall occur only to
the extent that all obligations of such Subsidiary Guarantor under all of its
guarantees of, and under all of its pledges of assets or other security
interests which secure, other Indebtedness of the Company or any Subsidiary
shall also terminate or be released upon such sale or other disposition. Each
Subsidiary Guarantor that is designated as an Unrestricted Subsidiary in
accordance with the Indenture shall be released from its Subsidiary Guarantee
and related obligations set forth in the Indenture for so long as it remains an
Unrestricted Subsidiary.
 
CERTAIN COVENANTS
 
     The Indenture contains, among others, the following covenants:
 
  Limitation on Incurrence of Additional Indebtedness
 
     The Company will not, and will not permit any of the Subsidiaries to,
directly or indirectly, issue, incur, assume, guarantee, become liable,
contingently or otherwise, with respect to or otherwise become responsible for
the payment of (collectively, "incur") any Indebtedness (other than Permitted
Indebtedness); provided, however, that if no Default or Event of Default with
respect to the Notes shall have occurred and be continuing at the time or as a
consequence at the incurrence of such Indebtedness, the Company may incur
Indebtedness and any Subsidiary may incur Indebtedness, if on the date of the
incurrence or issuance, the Company's Consolidated EBITDA Coverage Ratio would
have been greater than 2.0 to 1.0.
 
     For purposes of determining any particular amount of Indebtedness under
this covenant, guarantees by the Company or any of the Subsidiaries of
Indebtedness of the Company or any of the Subsidiaries otherwise included in the
determination of such amount shall not also be included.
 
     Notwithstanding anything to the contrary in this covenant, no Subsidiary
that is not already a Subsidiary Guarantor shall incur any Indebtedness with
respect to any Indebtedness of the Company or any other Subsidiary unless such
Subsidiary, the Company and the Trustee execute and deliver a supplemental
indenture evidencing such Subsidiary's Subsidiary Guarantee of the Notes, such
Subsidiary Guarantee to be a senior unsecured obligation of such Subsidiary on
the same terms as the Subsidiary Guarantees by the other Subsidiary Guarantors.
                                       66
<PAGE>   71
 
     For purposes of determining any particular amount of Indebtedness incurred
under this covenant, any Indebtedness of the Company or any Subsidiary incurred
for, or related to, a Person other than another Subsidiary or the Company, as
applicable, shall be deemed to be in an amount equal to the greater of (i) the
lesser of (a) the full amount of the Indebtedness of such other Person or (b)
the fair market value of the assets and properties of the Company or such
Subsidiary, as to which the holder or holders of such Indebtedness are expressly
limiting the obligations of the Company or such Subsidiary, the value of which
assets and properties of the Company or any Subsidiary will be as determined in
good faith by the Board of Directors of the Company or such Subsidiary, as
applicable (which determinations shall be evidenced by a resolution of the Board
of Directors of the applicable Person), and (ii) the amount of the Indebtedness
of such other Person as has been expressly contractually assumed or guaranteed
by the Company or such Subsidiary.
 
     In addition, neither the Company nor any Subsidiary Guarantor may, directly
or indirectly, in any event incur any Indebtedness that by its terms (or by the
terms of any agreement governing such Indebtedness) is subordinated to any other
Indebtedness of the Company or such Subsidiary Guarantor, as the case may be,
unless such Indebtedness is also by its terms (or by the terms of any agreement
governing such Indebtedness) made expressly subordinate to the Notes or the
Subsidiary Guarantee of such Subsidiary Guarantor, as the case may be, to the
same extent and in the same manner as such Indebtedness is subordinated pursuant
to subordination provisions that are most favorable to the holders of any other
Indebtedness of the Company or such Subsidiary Guarantor, as the case may be.
 
  Limitation on Restricted Payments
 
     The Company will not, and will not permit any of the Subsidiaries to,
directly or indirectly, make any Restricted Payment, if at the time of such
Restricted Payment, and on a pro forma basis after giving effect thereto:
 
     (i) a Default or an Event of Default under the Indenture has occurred and
is continuing;
 
     (ii) the aggregate amount expended for all Restricted Payments subsequent
to the Issue Date exceeds the sum of (without duplication):
 
          (a) 50% of aggregate Consolidated Net Income of the Company (or if
     such Consolidated Net Income is a loss, minus 100% of such loss) earned on
     a cumulative basis during the period beginning on the first day of the
     month containing the Issue Date and ending on the last date of the
     Company's fiscal quarter immediately preceding such Restricted Payment;
     plus
 
          (b) 100% of the aggregate Net Proceeds received by the Company from
     any Person other than a Subsidiary from the issuance and sale subsequent to
     the Issue Date of Qualified Capital Stock (excluding (1) any Qualified
     Capital Stock paid as a dividend on any Capital Stock or as interest on any
     Indebtedness, (2) the issuance of Qualified Capital Stock upon the
     conversion of, or in exchange for, any Qualified Capital Stock and (3) any
     Qualified Capital Stock with regard to issuances and sales financed
     directly or indirectly using funds borrowed from the Company or any
     Subsidiary, until and to the extent such borrowing is repaid); plus
 
          (c) to the extent not otherwise included in Consolidated Net Income,
     dividends, repayments of loans or advances, or other transfers of assets,
     in each case to the Company or a Subsidiary after the date of the Indenture
     from any Unrestricted Subsidiary or from the redesignation of an
     Unrestricted Subsidiary as a Subsidiary (valued in each case as provided in
     the definition of Investment) other than amounts constituting Permitted
     Unrestricted Subsidiary Investments; plus
 
          (d) $5.0 million; and
 
     (iii) the Company would not be able to incur $1.00 of additional
Indebtedness (excluding Permitted Indebtedness) as provided in the first
paragraph of "-- Limitation on Incurrence of Additional Indebtedness".
 
                                       67
<PAGE>   72
 
     The foregoing provisions of this covenant will not prevent the payment of
any dividend within 60 days after the date of its declaration if the dividend
would have been permitted on the date of declaration; provided, however,
payments made in accordance with this paragraph shall be counted for purposes of
computing amounts expended pursuant to subclause (ii) in the immediately
preceding paragraph.
 
  Limitation on Assets Sales
 
     The Company may not, and may not permit any of its Subsidiaries to, engage
in an Asset Sale unless (i) the Company (or the Subsidiary, as the case may be)
receives consideration at the time of such Asset Sale at least equal to the fair
market value (evidenced by a resolution of the Board of Directors set forth in
an Officers' Certificate delivered to the Trustee for an Asset Sale or series of
related Asset Sales involving assets of the Company or its Subsidiaries having
an aggregate value of more than $5.0 million) of the assets or Capital Stock
issued or sold or otherwise disposed of and (ii) the consideration therefor
received by the Company or such Subsidiary is in the form of cash and Cash
Equivalents or Permitted Industry Investments; provided that the amount of any
liabilities (as shown on the Company's or such Subsidiary's most recent balance
sheet) of the Company or any Subsidiary (other than contingent liabilities and
liabilities that are by their terms subordinated to the Notes or the Subsidiary
Guarantees) that are assumed by the transferee of any such assets pursuant to a
customary novation agreement that releases the Company or such Subsidiary from
further liability shall be deemed to be cash for purposes of this provision (but
shall not be deemed to be "Excess Proceeds" as defined below); and provided
further, that the Company or such Subsidiary may accept proceeds from such Asset
Sale in other than cash, and Cash Equivalents or Permitted Industry Investments
or any combination of the foregoing if the aggregate amount of all proceeds from
all Asset Sales after the Issue Date that are other than cash and Cash
Equivalents or Permitted Industry Investments after such Asset Sale, does not
exceed 15% of Consolidated Net Tangible Assets at the date of such Asset Sale.
 
     Within 365 days after the receipt of any Net Available Proceeds from any
Asset Sale, the Company (or the Subsidiary, as the case may be) may (i) apply
all or any part of the Net Available Proceeds therefrom to repay Senior
Indebtedness of the Company or Guarantor Senior Indebtedness of a Subsidiary
Guarantor or (ii) invest all or any part of the Net Available Proceeds thereof
in Permitted Industry Investments made by the Company or a Subsidiary or, to the
extent not so applied during such 365-day period, to such investments
specifically identified during such 365-day period reasonably anticipated in
good faith by the Board of Directors of the Company to be expended within 180
days after being specifically identified (such 180-day period, the "Project
Period"). Pending the final application of any such Net Available Proceeds, the
Company may temporarily reduce borrowings under any revolving credit facility or
otherwise invest such Net Available Proceeds in any manner that is not
prohibited by the Indenture. Any Net Available Proceeds from Asset Sales
occurring on or after the Issue Date that are not applied or invested within 365
days of the receipt thereof (or if later, within 35 Business Days following an
applicable Project Period) as provided in the first sentence of this paragraph
will be deemed to constitute "Excess Proceeds". When the aggregate amount of
Excess Proceeds equals or exceeds $10.0 million, the Company will be required to
make an offer to all Holders of Notes (an "Asset Sale Offer") to purchase the
maximum principal amount of Notes that may be purchased out of such Excess
Proceeds, at an offer price in cash in an amount equal to 100% of the principal
amount thereof, plus accrued and unpaid interest thereon to the date of purchase
in accordance with the procedures set forth in the Indenture and liquidated
damages as set forth in the Registration Rights Agreement; provided, however,
that, if the Company is required to apply such Excess Proceeds to repurchase, or
to offer to repurchase, any Pari Passu Indebtedness, the Company shall only be
required to offer to repurchase the maximum principal amount of Notes that may
be purchased out of the amount of such Excess Proceeds multiplied by a fraction,
the numerator of which is the aggregate principal amount of Notes outstanding
and the denominator of which is the aggregate principal amount of Notes
outstanding plus the aggregate principal amount of Pari Passu Indebtedness
outstanding. To the extent that the aggregate amount of Notes and Pari Passu
Indebtedness tendered pursuant to an Asset Sale Offer is less than the amount
that the Company is required to repurchase, the Company may use any of such
remaining Excess Proceeds for general corporate purposes. If the aggregate
principal amount of Notes surrendered by Holders thereof exceeds the amount that
the Company is required to repurchase, the Trustee shall select the Notes to be
purchased on a pro rata basis. Upon completion of such Asset Sale Offer, the
amount of Excess Proceeds shall be reset at zero.
                                       68
<PAGE>   73
 
     The Credit Facility and any future credit agreements or other amendments
relating to other Senior Indebtedness to which the Company or any of its
Subsidiaries becomes a party may contain limitations on the ability of the
Company or any such Subsidiary to make or consummate an Asset Sales Offer. In
the event that an Asset Sales Offer occurs at a time when the Company is
prohibited from purchasing the Notes, the Company could seek the consent of its
lenders to the purchase of the Notes or could attempt to repay or refinance the
borrowings containing such prohibition. If the Company does not obtain such a
consent or repay such borrowings, the Company may be prohibited from purchasing
the Notes.
 
     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 an Asset Sale 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 make an Asset Sale Offer.
 
  Limitation on Liens Securing Indebtedness
 
     The Company will not, and will not permit any of the Subsidiaries to,
create, incur, assume or suffer to exist any Liens (other than Permitted Liens)
upon any of their respective Properties securing (i) any Indebtedness of the
Company, unless the Notes are equally and ratably secured or (ii) any
Indebtedness of any Subsidiary Guarantor, unless the Notes or the Subsidiary
Guarantees are equally and ratably secured; provided that if such Indebtedness
is expressly subordinated to the Notes or the Subsidiary Guarantees, the Lien
securing such Indebtedness will be subordinated and junior to the Lien securing
the Notes or the Subsidiary Guarantees, with the same relative priority as such
subordinated Indebtedness will have with respect to the Notes or the Subsidiary
Guarantees, as the case may be.
 
  Limitation on Payment Restrictions Affecting Subsidiaries
 
     The Company will not, and will not permit any Subsidiary to, directly or
indirectly, create or suffer to exist or allow to become effective any
consensual encumbrance or restriction of any kind (i) on the ability of any of
the Subsidiaries (a) to pay dividends or make other distributions on its Capital
Stock or make payments on any Indebtedness owed to the Company or any other
Subsidiary, (b) to make loans or advances to the Company or any other Subsidiary
or (c) to transfer any of its Property to the Company or any other Subsidiary or
(ii) on the ability of such Person or any other subsidiary of such Person to
receive or retain any such (a) dividends, distributions or payments, (b) loans
or advances or (c) transfers of Property (any such restriction being referred to
herein as a "Payment Restriction"), except for such encumbrances or restrictions
existing under or by reason of (1) the Credit Facility as in effect from time to
time, (2) customary provisions restricting subletting or assignment of any lease
governing a leasehold interest of the Company or any Subsidiary, (3) any
instrument governing Indebtedness of a Person acquired by the Company or a
Subsidiary at the time of such acquisition, which encumbrance or restriction is
not applicable to any Person, other than the Person, or the Property of the
Person, so acquired, provided that such Indebtedness was not incurred in
anticipation of such acquisition, (4) with respect to clauses (i)(c) and (ii)(c)
above, Purchase Money Obligations for Property acquired in the ordinary course
of business, (5) Indebtedness existing pursuant to a written agreement in effect
on the date of the Indenture, (6) Indebtedness under the Indenture or (7)
Indebtedness incurred to refinance, refund, extend or renew Indebtedness
referred to in clause 1, 3, 4 or 5 above, provided that the Payment Restrictions
contained therein are not materially more restrictive than those provided for in
the Indebtedness being refinanced, refunded, extended or renewed.
 
  Limitation on Transactions with Related Persons
 
     Neither the Company nor any of the Subsidiaries will (i) sell, lease,
transfer or otherwise dispose of any of its Property to, (ii) purchase any
property from, (iii) make any Investment (other than Permitted Unrestricted
Subsidiary Investments and other Investments that do not breach the covenant
described under the caption "-- Limitation on Restricted Payments") in, or (iv)
enter into any contract or agreement with or for the benefit of, a Related
Person of the Company or any Subsidiary (other than the Company or any such
Subsidiary in which no Related Person (other than the Company or another
Wholly-Owned Subsidiary)
                                       69
<PAGE>   74
 
owns, directly or indirectly, an equity interest) (a "Related Party
Transaction"), unless (a) such Related Party Transaction or series of associated
Related Party Transactions is on terms that are no less favorable to the Company
or such Subsidiary, as the case may be, than those that could be obtained in a
comparable arm's length transaction with an unrelated third party, (b) with
respect to any Related Party Transaction or series of associated Related Party
Transactions involving aggregate payments in excess of $1.0 million, the Company
delivers, within 30 days of such Related Party Transaction or series of
associated Related Party Transactions, an Officers' Certificate to the Trustee
certifying that such Related Party Transaction or series of associated Related
Party Transactions complies with the immediately preceding clause (a), and (c)
with respect to a Related Party Transaction or series of associated Related
Party Transactions involving payments of $5.0 million or more, the Company
delivers, within 30 days of such Related Party Transaction or series of
associated Related Party Transactions, an Officers' Certificate to the Trustee
certifying that (1) such Related Party Transaction or series of associated
Related Party Transactions complies with clause (a) above and (2) such Related
Party Transaction or series of associated Related Party Transactions has been
approved by a majority of the independent directors of the Company.
Notwithstanding anything to the contrary in the foregoing, the foregoing
restrictions shall not apply to (A) Related Party Transactions that are approved
by the Board of Directors of the Company and such Subsidiary, if applicable, as
in the best interests of the Company or such Subsidiary, which transactions
together with all other Related Party Transactions in a related series involve
or have an aggregate value not exceeding $1.0 million in each fiscal year; (B)
fees and compensation paid to or agreements with officers, directors, employees
or consultants of the Company or any Subsidiary in each case that are
reasonable, as determined by the Board of Directors or senior management thereof
in good faith; (C) Employee Stock Repurchases, (D) transactions described in
"Certain Relationships and Related Transactions" and (E) Restricted Payments
that are not prohibited by the covenants described under the caption
"-- Limitation on Restricted Payments".
 
  Limitation on Conduct of Business
 
     The Company and the Subsidiaries will be operated in a manner such that
their business activities will be in the oilfield services business and related
products and services, including, but not limited to, (i) rental of downhole
tools, general oil field equipment, petrochemical equipment and industrial and
other equipment (which may include equipment not used in the oil and gas
industry), (ii) drilling services, (iii) pipeline testing services, and (iv)
such other businesses as are reasonably necessary or desirable to facilitate the
conduct and operations of the foregoing businesses.
 
  Reports
 
     The Company will file on a timely basis with the Commission, to the extent
such filings are accepted by the Commission and whether or not the Company has a
class of securities registered under the Exchange Act, the annual reports,
quarterly reports and other documents that the Company would be required to file
if it were subject to Section 13 or 15 of the Exchange Act. The Company is also
required (i) to file with the Trustee (with exhibits), and provide to each
Holder of Notes or, upon request, to a prospective Holder of Notes (without
exhibits), without cost to such Holder or prospective Holder, copies of such
reports and documents within 15 days after the date on which the Company files
such reports and documents with the Commission or the date on which the Company
would be required to file such reports and documents if the Company were so
required and (ii) if filing such reports and documents with the Commission is
not accepted by the Commission or is prohibited under the Exchange Act, to
supply at its cost copies of such reports and documents (including any exhibits
thereto) to any Holder of Notes promptly upon written request.
 
  Future Designation of Restricted and Unrestricted Subsidiaries
 
     The foregoing covenants (including calculation of financial ratios and the
determination of limitations on the incurrence of Indebtedness and Liens) may be
affected by the designation by the Company of any existing or future Subsidiary
of the Company as an Unrestricted Subsidiary. The definition of "Unrestricted
Subsidiary" set forth under the caption "-- Certain Definitions" describes the
circumstances under which a
 
                                       70
<PAGE>   75
 
Subsidiary of the Company may be designated as an Unrestricted Subsidiary by the
Board of Directors of the Company.
 
  Sale-and-Leaseback Transactions
 
     The Company will not, and will not permit any Subsidiaries to, enter into
any sale-and-leaseback transaction; provided that the Company or any Subsidiary,
as applicable, may enter into a sale-and-leaseback transaction if (i) the
Company could have (a) incurred Indebtedness in an amount equal to the
Attributable Indebtedness relating to such sale-and-leaseback transaction
pursuant to the Consolidated EBITDA Coverage Ratio test set forth in the first
paragraph of the covenant described above under the caption "-- Limitation on
Incurrence of Additional Indebtedness" and (b) created a Lien to secure such
Indebtedness pursuant to the covenant described above under the caption
"-- Limitation on Liens Securing Indebtedness", (ii) the fair market value of
the consideration of such sale-and-leaseback transaction is at least equal to
the fair market value (as determined in good faith by the Board of Directors and
set forth in an Officers' Certificate delivered to the Trustee) of the Property
that is the subject of such sale-and-leaseback transaction and (iii) the
transfer of assets in such sale-and-leaseback transaction is permitted by, and
the Company applies the proceeds of such transaction in compliance with, the
covenant described above under the caption "-- Limitation on Asset Sales".
 
  Issuances and Sales of Capital Stock of Wholly-Owned Subsidiaries
 
     The Company (i) may not, and may not permit any Wholly-Owned Subsidiary to
transfer, convey, sell or otherwise dispose of any Capital Stock of any
Wholly-Owned Subsidiary to any Person (other than the Company or a Wholly-Owned
Subsidiary), unless (a) such transfer, conveyance, sale or other disposition is
of all the Capital Stock of such Wholly-Owned Subsidiary and (b) the cash Net
Available Proceeds from such transfer, conveyance, sale or other disposition are
applied in accordance with the covenant described above under the caption
"-- Limitation on Asset Sales", and (ii) may not permit any Wholly-Owned
Subsidiary of the Company to issue any of its Capital Stock or any warrants,
options or other rights to acquire Capital Stock (but excluding any debt
security that is convertible into, or exchangeable for, Capital Stock) to any
Person other than to the Company or a Wholly-Owned Subsidiary; except, in the
case of both clauses (i) and (ii) above, with respect to dispositions or
issuances by a Wholly-Owned Subsidiary of the Company as contemplated in clauses
(i) and (ii) of the definition of "Wholly-Owned Subsidiary".
 
MERGER, CONSOLIDATION OR SALE OF SUBSTANTIALLY ALL ASSETS
 
     The Company will not consolidate with or merge with any other Person or
convey, transfer or lease all or substantially all of its Property to any
Person, unless: (i) the Company survives such merger or the Person formed by
such consolidation or into which the Company is merged or that acquires by
conveyance or transfer, or which leases, all or substantially all of the
Property of the Company is a Person organized and existing under the laws of the
United States of America or any State thereof or the District of Columbia and
expressly assumes, by supplemental indenture, the due and punctual payment of
the principal of, and premium, if any, and interest on all the Notes and the
performance of every other covenant and obligation of the Company under the
Indenture; (ii) immediately before and after giving effect to such transaction,
no Default or Event of Default exists; (iii) immediately after giving effect to
such transaction on a pro forma basis, the Consolidated Net Worth of the Company
(or the surviving entity if the Company is not continuing) is equal to or
greater than the Consolidated Net Worth of the Company immediately before such
transaction and (iv) immediately after giving effect to such transaction on a
pro forma basis, the Company (or the surviving entity if the Company is not
continuing) would be able to incur $1.00 of additional Indebtedness (excluding
Permitted Indebtedness) under the tests described in the first paragraph of
"-- Certain Covenants -- Limitation on Incurrence of Additional Indebtedness".
Upon any such consolidation, merger, conveyance, lease or transfer in accordance
with the foregoing, the successor Person formed by such consolidation or into
which the Company is merged or to which such conveyance, lease or transfer is
made will succeed to, and be substituted for, and may exercise every right and
power of, the Company under the Indenture with the same effect as if such
successor had been named as the Company therein, and thereafter (except in the
case of a lease) the
 
                                       71
<PAGE>   76
 
predecessor corporation will be relieved of all further obligations and
covenants under the Indenture and the Notes.
 
EVENTS OF DEFAULT
 
     The following constitute Events of Default under the Indenture:
 
     (i) default in the payment of principal of, or premium, if any, on the
Notes when due at maturity, upon repurchase, upon acceleration or otherwise,
including failure of the Company to repurchase the Notes required to be
repurchased, at the required purchase price, upon a Change of Control or an
Asset Sale Offer and failure to make, when due, any optional redemption payment;
 
     (ii) default in the payment of any installment of interest on the Notes
when due (including any interest payable in connection with optional redemption
payments) and continuance of such default for 30 days;
 
     (iii) default on any other Indebtedness of the Company, any Subsidiary
Guarantor or any other Subsidiary if either (a) such default results from the
failure to pay principal of, premium, if any, or interest on any such
Indebtedness when due in excess of $5.0 million and continuance of such default
beyond any applicable cure, forbearance or notice period, or (b) as a result of
such default, the maturity of such Indebtedness has been accelerated prior to
its scheduled maturity, without such default and acceleration having been
rescinded or annulled within a period of 10 days, and the principal amount of
such Indebtedness, together with the principal amount of any other such
Indebtedness in default, or the maturity of which has been so accelerated,
aggregates $5.0 million or more;
 
     (iv) default in the performance, or breach, of any other covenant of the
Company or any Subsidiary Guarantor in the Indenture and failure to remedy such
default within a period of 45 days after written notice thereof from the Trustee
or Holders of 25% in principal amount of the outstanding Notes;
 
     (v) the entry by a court of one or more judgments or orders against the
Company, any Subsidiary Guarantor or any other Subsidiary in an aggregate amount
in excess of $5.0 million and which are not covered by insurance written by
third parties that has not been vacated, discharged, satisfied or stayed pending
appeal within 60 days from the entry thereof;
 
     (vi) certain events of bankruptcy, insolvency or reorganization in respect
of the Company or any Material Subsidiary; or
 
     (vii) a Subsidiary Guarantee by a Subsidiary Guarantor that is a Material
Subsidiary shall cease to be in full force and effect (other than a release of a
Subsidiary Guarantor by designation of such Subsidiary Guarantor as an
Unrestricted Subsidiary or as otherwise provided under the Indenture in
connection with the sale, liquidation or other transfer of such Subsidiary
Guarantor) or any Subsidiary Guarantor shall deny, disaffirm or seek to revoke
its obligations with respect thereto.
 
     If any Event of Default (other than an Event of Default specified in clause
(vi) above) occurs and is continuing, then and in every such case the Trustee or
the Holders of not less than 25% in principal amount of the Notes then
outstanding may declare the unpaid principal of (or the Change of Control
Purchase Price if the Event of Default includes failure to pay the Change of
Control Purchase Price), and accrued and unpaid interest on, all the Notes then
outstanding to be due and payable, by a notice in writing to the Company (and to
the Trustee, if given by Holders) and upon any such declaration such principal
amount, premium, if any, and accrued and unpaid interest shall become
immediately due and payable, notwithstanding anything contained in the Indenture
or the Notes to the contrary. If an Event of Default specified in clause (vi)
above occurs, all unpaid principal of, premium, if any, and accrued interest on,
the Notes then outstanding will become due and payable, without any declaration
or other act on the part of the Trustee or any Holder.
 
     The Holders of a majority in principal amount of Notes then outstanding, by
written notice to the Company, the Subsidiary Guarantors and the Trustee, may
rescind and annul a declaration of acceleration and its consequences if (i) the
Company or any Subsidiary Guarantor has paid or deposited with such Trustee a
sum sufficient to pay (a) all overdue installments of interest on all the Notes,
(b) the principal of, and premium, if any, on, any Notes that have become due
otherwise than by such declaration of acceleration and

interest thereon at the rate or rates prescribed therefor in the Notes, (c) to
the extent that payment of such interest is lawful, interest on the defaulted
interest at the rate or rates prescribed therefor in the Notes and (d) all money
paid or advanced by the Trustee thereunder and the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel;
(ii) all Events of Default, other than the non-payment of the principal of any
Notes that have become due solely by such declaration of acceleration, have been
cured or waived as provided in the Indenture; and (iii) the rescission would not
conflict with any judgment or decree of a court of competent jurisdiction. No
such rescission will affect any subsequent Event of Default or impair any right
consequent thereon.
 
     Except as described in the next paragraph, no Holder of any of the Notes
will have any right to institute any proceeding, judicial or otherwise, or for
the appointment of a receiver or trustee or pursue any remedy under the
Indenture, unless (i) such Holder has previously given notice to the Trustee of
a continuing Event of Default, (ii) the Holders of not less than 25% in
principal amount of the outstanding Notes have made written request to such
Trustee to institute proceedings in respect of such Event of Default in its own
name as Trustee under the Indenture, (iii) such Holder or Holders have offered
to such Trustee reasonable indemnity against the costs, expenses and liabilities
to be incurred in compliance with such request, (iv) such Trustee for 30 days
after its receipt of such notice, request and offer of indemnity has failed to
institute any such proceeding and (v) no direction inconsistent with such
written request has been given to such Trustee during such 30-day period by the
Holders of a majority in principal amount of the outstanding Notes.
 
     The Holder of any Note will have the right, which is absolute and
unconditional, to receive payment of the principal of, premium, if any, and
interest on such Note on the stated maturity therefor and to institute suit for
the enforcement of any such payment, and such right may not be impaired without
the consent of such Holder.
 
     The Holders of a majority in principal amount of the Notes will have the
right to direct the time, method and place of conducting any proceeding for any
remedy available to the Trustee or exercising any trust or power conferred on
such Trustee, provided that (i) such direction is not in conflict with any rule
of law or with the Indenture and (ii) the Trustee may take any other action
deemed proper by such Trustee that is not inconsistent with such direction.
 
MODIFICATIONS AND WAIVERS
 
     The Company and the Trustee may amend the Indenture or rights thereunder
may be waived with the consent of the Subsidiary Guarantors and the Holders of
at least a majority of the principal amount of Notes then outstanding, provided
that, without the consent of each Holder of Notes affected thereby, no such
modification or waiver will be made with regard to: (i) a default in the payment
of principal or premium, if any, or interest on the Notes; (ii) a reduction of
the interest rate on or principal amount of the Notes, an extension of the
maturity schedule of the Notes or a modification of the redemption or repurchase
provisions of the Notes; (iii) contractual subordination in the right of payment
of the Notes in a manner that is adverse to the Holders; (iv) a change in the
currency in which the Notes are payable; (v) a change in the percentage required
by this provision; or (vi) a change in any Holder's right to receive payment of
the proceeds of, premium, if any, and interest on the Notes and to institute
suit for the enforcement of such payment.
 
     Notwithstanding the foregoing, without the consent of a Holder of Notes,
the Company and the Trustee may amend or supplement the Indenture, the
Subsidiary Guarantees 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 assumption of the Company's obligations
to Holders of Notes in the case of a merger or consolidation, to make any change
that would provide any additional rights or benefits to the Holders of Notes or
that does not adversely affect the legal rights under the Indenture of any such
Holder, or to comply with requirements of the Commission in order to effect or
maintain the qualification of the Indenture under the Trust Indenture Act.

SATISFACTION AND DISCHARGE OF INDENTURE; DEFEASANCE
 
     The Company may at any time terminate its Obligations under the Notes and
the Indenture, and the Subsidiary Guarantors may, at such times, terminate their
corresponding obligations under the Subsidiary Guarantees and the Indenture,
with certain exceptions specified in the Indenture, by irrevocably depositing in
trust cash or obligations of the United States government and its agencies for
payment of principal of, and interest on, the Notes to redemption or maturity,
subject to the satisfaction of certain conditions.
 
     Subject to the conditions described below, at the Company's option, either
(i) the Company and the Subsidiary Guarantors will be deemed to have been
discharged from their obligations with respect to the Notes and Subsidiary
Guarantees and the provisions of the Indenture on the 91st day after the
applicable conditions set forth below have been satisfied or (ii) the Company
and the Subsidiary Guarantors will cease to be under any obligation to comply
with certain restrictive covenants, including those described under "-- Certain
Covenants", at any time after the applicable conditions set forth below have
been satisfied: (a) the Company or any Subsidiary Guarantor has deposited or
caused to be deposited irrevocably with the Trustee as trust funds in trust,
specifically pledged as security for, and dedicated solely to, the benefit of
the Holders (1) money or (2) United States government obligations, which through
the payment of interest and principal in respect thereof in accordance with
their terms will provide (without any reinvestment of such interest or
principal), not later than one day before the due date of any payment, money or
(3) a combination of (1) and (2), in an amount sufficient, in the opinion (with
respect to (2) and (3)) of a nationally recognized firm of independent public
accountants expressed in a written certification thereof delivered to the
Trustee at or prior to the time of such deposit, to pay and discharge each
installment of principal of, premium, if any, and interest on, the outstanding
Notes on the dates such installments are due; (b) no Default or Event of Default
has occurred or is continuing on the date of such deposit or will occur as a
result of such deposit and such deposit will not result in a breach or violation
of, or constitute a default under, any other instrument to which the Company or
a Subsidiary Guarantor or any Subsidiary is a party or by which any of them is
bound, as evidenced to the Trustee in an Officers' Certificate delivered to the
Trustee concurrently with such deposit; (c) the Company has delivered to the
Trustee an opinion of tax counsel reasonably acceptable to the Trustee (which
counsel may be an employee of the Company) to the effect that Holders will not
recognize income, gain or loss for federal income tax purposes as a result of
the Company's exercise of its option described above and will be subject to
federal income tax on the same amount and in the same manner and at the same
time as would have been the case if such option had not been exercised; provided
that in the case of the Notes being discharged pursuant to clause (i) above,
such opinion shall be based upon and shall identify a ruling by the Internal
Revenue Service or a change in law to that effect (it being understood that (1)
such opinion will also state, if applicable, that such ruling or change in law
is consistent with the conclusions reached in such opinion and (2) the Trustee
will be under no obligation to investigate the basis or correctness of such
opinion); (d) the Company has delivered to the Trustee an opinion of counsel
(which counsel may be an employee of the Company) to the effect that the
Company's exercise of its option described above will not result in any of the
Company, the Trustee or the trust created by the Company's deposit of funds
hereunder becoming or being deemed to be an "investment company" under the
Investment Company Act of 1940, as amended; (e) the Company or any Subsidiary
Guarantor has paid or duly provided for payment of all amounts then due to the
Trustee pursuant to the terms of the Indenture; and (f) the Company has
delivered to the Trustee an Officers' Certificate and an opinion of counsel
(which counsel may be an employee of the Company), each stating that all
conditions precedent provided for in the Indenture relating to the satisfaction
and discharge of the Indenture have been complied with.
 
GOVERNING LAW
 
     The Indenture, the Notes and the Subsidiary Guarantees will be governed by,
and construed in accordance with, the laws of the State of New York, but without
giving effect to applicable principles of conflicts of law to the extent that
the application of the law of another jurisdiction would be required thereby.
 
                                       74
<PAGE>   79
 
THE TRUSTEE
 
     The Indenture provides that, except during the continuance of an Event of
Default, the Trustee need perform only those duties that are specifically set
forth (or incorporated by reference) in the Indenture and no others. During the
existence of an Event of Default, the Trustee will exercise such rights and
powers vested in it by the Indenture, and use the same degree of care and skill
in such exercise as a prudent person would exercise or use under the
circumstances in the conduct of such person's own affairs.
 
     The Indenture contains certain limitations on the rights of the Trustee,
should it become a creditor of the Company, to obtain payments of claims in
certain cases or to realize on certain property received in respect of any such
claims as security or otherwise.
 
BOOK ENTRY; DELIVERY AND FORM
 
     Except as described in the next paragraph, the Exchange Notes initially
will be represented by a single, permanent global certificate in definitive,
fully registered form (the "Global Note"). The Global Note will be deposited on
the Exchange Date with, or on behalf of, DTC and registered in the name of a
nominee of DTC. The Global Note will be subject to certain restrictions on
transfer set forth therein and will bear the legend regarding such restrictions
set forth under "Transfer Restrictions".
 
     Exchange Notes (i) originally purchased by Institutional Accredited
Investors or transferred to Institutional Accredited Investors or "foreign
purchasers" who are not Qualified Institutional Buyers or (ii) held by Qualified
Institutional Buyers who elect to take physical delivery of their certificates
instead of holding their interest through the Global Note (and which are thus
ineligible to trade through DTC) (collectively referred to herein as the
"Non-Global Purchasers") will be issued in registered certificated form
("Certificated Securities"). Upon the transfer to a Qualified Institutional
Buyer of any Certificated Security initially issued to a Non-Global Purchaser,
such Certificated Security will, unless the transferee requests otherwise or the
Global Note has previously been exchanged in whole for Certificated Securities,
be exchanged for an interest in the Global Note. For a description of the
restrictions on the transfer of Certificated Securities and any interest in the
Global Note, see "Transfer Restrictions".
 
  The Global Note
 
     The Company expects that pursuant to procedures established by DTC (i) upon
the issuance of the Global Note, DTC or its custodian will credit, on its
internal system, the principal amount of Exchange Notes of the individual
beneficial interests represented by such Global Note to the respective accounts
for persons who have accounts with DTC and (ii) ownership of beneficial
interests in the Global Note will be shown on, and the transfer of such
ownership will be effected only through, records maintained by DTC or its
nominee (with respect to interests of participants) and the records of
participants (with respect to interests of persons other than participants).
Ownership of beneficial interests in the Global Note will be limited to persons
who have accounts with DTC ("participants") or persons who invest through
participants. Qualified Institutional Buyers will hold their interests in the
Global Note directly through DTC, if they are participants in such system, or
indirectly through organizations which are participants in such system.
 
     So long as DTC or its nominee is the registered owner or holder of the
Exchange Notes, DTC or such nominee, as the case may be, will be considered the
sole owner or holder of the Exchange Notes represented by such Global Note for
all purposes under the Indenture. No beneficial owners of an interest in any
Global Note will be able to transfer that interest except in accordance with
DTC's procedures in addition to those provided for under the Indenture.
 
     Payments of the principal of, premium, if any, and interest on, the Global
Note will be made to DTC or its nominee, as the case may be, as the registered
owner thereof. None of the Company, the Trustee or any paying agent of the
Company will have any responsibility or liability for any aspect of the records
relating to or payments made on account of beneficial ownership interests in the
Global Note or for maintaining, supervising or reviewing any records relating to
such beneficial ownership interests.
 
                                       75
<PAGE>   80
 
     The Company expects that DTC or its nominee, upon receipt of any payment of
principal, premium, if any, or interest in respect of the Global Note, will
credit participants' accounts with payments in amounts proportionate to their
respective beneficial interests in the principal amount of the Global Note as
shown on the records of DTC or its nominee. The Company also expects that
payments by participants to owners of beneficial interests in the Global Note
held through such participants will be governed by standing instructions and
customary practice, as is now the case with securities held for the accounts of
customers registered in the names of nominees for such customers. Such payments
will be the responsibility of such participants.
 
     Transfers between participants in DTC will be effected in the ordinary way
in accordance with DTC rules and will be settled in clearinghouse funds. If a
holder requires physical delivery of a Certificated Security for any reason,
including to sell Exchange Notes to persons in states which require physical
delivery of the Certificated Securities, or to pledge such securities, such
holder must transfer its interest in the Global Note in accordance with the
normal procedures of DTC and with the procedures set forth in the Indenture.
 
     DTC has advised the Company that it will take any action permitted to be
taken by a holder of Outstanding Notes (including the presentation of
Outstanding Notes for exchange pursuant to the Exchange Offer) only at the
direction of one or more participants to whose account the interests in the
Outstanding Global Note are credited and only in respect of such portion of the
aggregate principal amount of Outstanding Notes as to which such participant or
participants have given such direction. However, if there is an Event of Default
under the Indenture, DTC will exchange the Global Note for Certificated
Securities, which it will distribute to its participants.
 
     DTC has advised the Company as follows: DTC is a limited purpose trust
company organized under laws of the State of New York, a member of the Federal
Reserve System, a "clearing corporation" within the meaning of the Uniform
Commercial Code and a "clearing agency" registered pursuant to the provisions of
Section 17A of the Exchange Act. DTC was created to hold securities for its
participants and facilitate the clearance and settlement of securities
transactions between participants through electronic book entry changes in
accounts of its participants, thereby eliminating the need for physical movement
of certificates. Participants include securities brokers and dealers, banks,
trust companies and clearing corporations and certain other organizations.
Indirect access to the DTC system is available to others, such as banks,
brokers, dealers and trust companies that clear through or maintain a custodial
relationship with a participant, either directly or indirectly.
 
     Although DTC has agreed to the foregoing procedures in order to facilitate
transfers of interests in the Global Note among participants of DTC, it is under
no obligation to perform such procedures, and such procedures may be
discontinued at any time. None of the Company, the Initial Purchaser or the
Trustee will have any responsibility for the performance by DTC or its
participants or indirect participants of their respective obligations under the
rules and procedures governing their operations.
 
  Certificated Securities
 
     If (i) DTC is at any time unwilling or unable to continue as a depositary
for the Global Note and a successor depositary is not appointed by the Company
within 90 days, (ii) an Event of Default has occurred and is continuing and the
registrar has received a request from DTC to issue Certificated Securities in
lieu of all or a portion of the Global Note (in which case the Company shall
deliver Certificated Securities within 30 days of such request) or (iii) the
Company determines not to have the Exchange Notes represented by the Global Note
and notifies DTC and the registrar thereof, Certificated Securities will be
issued in exchange for the Global Note.

period for which such lease has been extended or may, at the option of the
lessor, be extended). As used in the preceding sentence, the "net rental
payments" under any lease for any such period shall mean the sum of rental and
other payments required to be paid with respect to such period by the lessee
thereunder, excluding any amounts required to be paid by such lessee on account
of maintenance and repairs, insurance, taxes, assessments, water rates or
similar charges. In the case of any lease that is terminable by the lessee upon
payment of penalty, such net rental payment shall also include the amount of

     "Consolidated EBITDA" means, with respect to any Person for any period, the
Consolidated Net Income of such Person for such period increased (to the extent
deducted in determining Consolidated Net Income) by the sum of: (i) all income
taxes of such Person and its subsidiaries paid or accrued according to GAAP for
such period (other than income taxes attributable to extraordinary, unusual or
non-recurring gains or losses), (ii) all interest expense of such Person and its
subsidiaries paid or accrued in accordance with GAAP for such period (including

     "Consolidated EBITDA Coverage Ratio" means, with respect to any Person, the
ratio of (1) Consolidated EBITDA of such Person for the period (the "Pro Forma
Period") consisting of the most recent four full fiscal quarters for which
financial information in respect thereof is available immediately prior to the
date of the transaction giving rise to the need to calculate the Consolidated
EBITDA Coverage Ratio (the "Transaction Date") to (2) the aggregate Fixed
Charges which such Person will accrue during the fiscal quarter in which the

purposes of this definition, "Consolidated EBITDA" shall be calculated after
giving effect (without duplication), on a pro forma basis for the Pro Forma
Period (but no longer), to (i) any Investment, during the period commencing on

such incurrence, Investment, repayment, acquisition or asset sale had occurred
on the first day of the Reference Period and (iv) interest income reasonably
anticipated by the Company to be received during the Pro Forma Period from
Investments in Cash Equivalents, which Investments exist on the Transaction Date
or will exist as a result of the transaction giving rise to the need to
calculate the Consolidated EBITDA Coverage Ratio. For purposes of this
definition, "Fixed Charges" shall be calculated after giving effect (without
duplication), on a pro forma basis for the Forward Period, to any Indebtedness
incurred or repaid on or after the first day of the Forward Period and prior to
the Transaction Date. For purposes of calculating the Company's Consolidated
EBITDA Coverage Ratio, Indebtedness of a Subsidiary that is not a Wholly-Owned
Subsidiary (which Indebtedness is nonrecourse to the Company or any other
Subsidiary or any of their assets) shall be included only to the extent of the
Company's pro rata ownership interest in such Subsidiary.
 
     "Consolidated Net Income" of any Person means, for any period, the

period on a consolidated basis, determined in accordance with GAAP, provided
that (i) the net income of (a) any Unrestricted Subsidiary and (b) any other
Person in which such Person or any subsidiary thereof has an interest (which

                CERTAIN UNITED STATES FEDERAL TAX CONSIDERATIONS
 
     The following is a general discussion of the principal United States
federal income tax consequences of the purchase, ownership and disposition of
the Notes to initial purchasers thereof. This discussion is based on currently
existing provisions of the Code, existing, temporary and proposed Treasury
regulations promulgated thereunder, and administrative and judicial
interpretations thereof, all as in effect or proposed on the date hereof and all
of which are subject to change, possibly with retroactive effect, or different
interpretations. This discussion does not address the tax consequences to
subsequent purchasers of Notes and is limited to purchasers who hold the Notes
as capital assets, within the meaning of section 1221 of the Code. Moreover,
this discussion is for general information only and does not address all of the
tax consequences that may be relevant to particular initial purchasers in light
of their personal circumstances or to certain types of initial purchasers (such
as certain financial institutions, insurance companies, tax-exempt entities,
dealers in securities, persons who have hedged the risk of owning a Note and
foreign taxpayers), or the effect of any applicable state, local or foreign tax
law.
 
     PROSPECTIVE PURCHASERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS AS TO
THE PARTICULAR TAX CONSEQUENCES TO THEM OF THE PURCHASE, OWNERSHIP AND
DISPOSITION OF THE NOTES, INCLUDING THE APPLICABILITY OF ANY FEDERAL TAX LAWS OR
ANY STATE, LOCAL OR FOREIGN TAX LAWS, AND ANY CHANGES (OR PROPOSED CHANGES) IN
APPLICABLE TAX LAWS OR INTERPRETATIONS THEREOF.
 
  Payment of Interest on Notes
 
     Interest paid or payable on a Note will be taxable to a holder as ordinary
interest income, generally at the time it is received or accrued, in accordance
with such holder's regular method of accounting for United States federal income
tax purposes.
 
  Sale, Exchange or Retirement of the Notes
 
     Upon the sale, exchange, redemption, retirement at maturity or other
disposition of a Note, the holder generally will recognize taxable gain or loss
equal to the difference between the sum of cash plus the fair market value of
all other property received on such disposition (except to the extent such cash
or property is attributable to accrued but unpaid interest, which will be
taxable as ordinary income) and such holder's adjusted tax basis in the Note. A
holder's adjusted tax basis in a Note generally will equal the cost of the Note
to such holder, less any principal payments received by such holder.
 
     Gain or loss recognized on the disposition of a Note generally will be
capital gain or loss and will be long-term capital gain or loss if, at the time
of such disposition, the holder's holding period for the Note is more than one
year.
 
     The exchange of an Outstanding Note by a holder for an Exchange Note
pursuant to the terms set forth herein should not constitute a taxable exchange
for federal income tax purposes.
 
  Backup Withholding and Information Reporting
 
     Backup withholding and information reporting requirements may apply to
certain payments of principal, premium, if any, and interest on a Note, and to
proceeds of the sale or redemption of a Note before maturity. The Company, its
agent, a broker, the Trustee or any paying agent, as the case may be, will be
required to withhold from any payment that is subject to backup withholding a
tax equal to 31% of such payment if a holder fails to furnish his taxpayer
identification number (social security or employer identification number),
certify that such number is correct, certify that such holder is not subject to
backup withholding or otherwise comply with the applicable requirements of the
backup withholding rules. Certain holders, including all corporations, are not
subject to backup withholding and reporting requirements. Any amounts withheld
under the backup withholding rules from a payment to a holder will be allowed as
a credit against such holder's United States federal income tax and may entitle
the holder to a refund, provided that the required information is furnished to
the Internal Revenue Service.

                              PLAN OF DISTRIBUTION
 
     Each broker-dealer that receives Exchange Notes for its own account
pursuant to the Exchange Offer must acknowledge that it will deliver a
prospectus in connection with any resale of such Exchange Notes. The Prospectus,
as it may be amended or supplemented from time to time, may be used by a
broker-dealer in connection with resales of Exchange Notes received in exchange
for Outstanding Notes where such Outstanding Notes were acquired as a result of
market-making activities or other trading activities. The Company has agreed
that for a period of days after the Expiration Date, it will make this
Prospectus, as amended or supplemented, available to any broker-dealer for use
in connection with any such resale. In addition, until June 28, 1998, all
dealers effecting transactions in the Exchange Notes may be required to deliver
a prospectus.
 
     The Company will not receive any proceeds from any sales of the Exchange
Notes by broker-dealers. Exchange 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 Exchange Notes or a combination of such
methods of resale, at market prices prevailing at the time of resale, at prices
related to such prevailing market prices or negotiated prices. Any such resale
may be made directly to purchase or to or through brokers or dealer who may
receive compensation in the form of commissions or concessions from any such
broker-dealer and/or the purchasers of any such Exchange Notes. Any
broker-dealer that resells the Exchange Notes that were received by it for its
own account pursuant to the Exchange Offer and any broker or dealer that
participates in a distribution of such Exchange Notes may be deemed to be an
"underwriter" within the meaning of the Securities Act, and any profit on any
such resale of Exchange Notes and any commissions or concessions received by any
such persons may be deemed to be underwriting compensation under the Securities
Act. A broker-dealer that delivers such a prospectus to purchasers in connection
with such resales will be subject to certain of the civil liability provisions
under the Securities Act and will be bound by the provisions of the Registration
Rights Agreement (including certain indemnification rights and obligations).
 
     For a period of 90 days after the Expiration Date, the Company will
promptly send additional copies of this Prospectus and any amendment or
supplement to this Prospectus to any broker-dealer that requests such documents
in the Letter of Transmittal. The Company has agreed to pay certain expenses
incident to the Exchange Offer, other than commissions or concession of any
brokers or dealers, and will indemnify the holders of the Securities (including
any broker-dealers) against certain liabilities, including liabilities under the
Securities Act.
 
     By acceptance of this Exchange Offer, each broker-dealer that receives
Exchange Notes for its own account pursuant to the Exchange Offer agrees that,
upon receipt of notice from the Company of the happening of any event which
makes any statement in the Prospectus untrue in any material respect or which
request the making of any changes in the Prospectus in order to make the
statements therein not misleading (which notice the Company agrees to deliver
promptly to such broker-dealer), such broker-dealer will suspend use of the
Prospectus until the Company has amended or supplemented the Prospectus to
correct such misstatement or omission and has furnished copies of the amended or
supplemental Prospectus to such broker-dealer. If the Company shall give any
such notice to suspend the use of the Prospectus, it shall extend the 90-day
period referred to above by the number of days during the period from and
including the date of the giving of such notice to and including when
broker-dealers shall have received copies of the supplemented or amended
Prospectus necessary to permit resales of the Exchange Notes.
 
                                 LEGAL MATTERS
 
     Certain matters related to the validity of the Exchange Notes will be
passed upon for the Company by Fulbright & Jaworski L.L.P., Houston, Texas.

                         REPORT OF INDEPENDENT AUDITORS
 
To the Board of Directors and Stockholders
  of Dailey International Inc.
 
     We have audited the accompanying consolidated balance sheets of Dailey
International Inc., as of April 30, 1997 and 1996, and the related consolidated
statements of operations, stockholders' equity, and cash flows for each of the
three years in the period ended April 30, 1997. 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 audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
Dailey International Inc. at April 30, 1997 and 1996, and the consolidated
results of its operations and its cash flows for each of the three years in the
period ended April 30, 1997, in conformity with generally accepted accounting
principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                 APRIL 30, 1997
 
1. ORGANIZATION AND PUBLIC OFFERING
 
     The accompanying consolidated financial statements reflect the operations
of Dailey Petroleum Services Corp., a Delaware corporation, which was merged
with Dailey Corporation (which changed its name to Dailey Petroleum Services
Corp.) in June 1996. The Company subsequently changed its name to Dailey
International Inc. Dailey International Inc. and its predecessor are hereinafter
referred to as the "Company" or "Dailey."
 
     The Company provides directional drilling services and designs,
manufactures and rents technologically-advanced downhole tools for oil and gas
drilling and workover applications. Founded in 1945 as a rental tool company,
Dailey began offering directional drilling services in 1984 and currently
provides such services in the Gulf of Mexico, the United States Gulf Coast
region, and most recently, Venezuela, Louisiana and the Austin Chalk formation
in Texas. The Company operates in one business segment.
 
     Prior to June 1996, Dailey was a wholly owned subsidiary of Lawrence
Industries, Inc. ("Lawrence"). In June 1996, in preparation for the initial
public offering of Class A Common Stock of Dailey, Lawrence reorganized its
ownership of the Company into a holding company structure through a forward
triangular merger of Dailey Petroleum Services Corp., into a newly-formed,
wholly-owned indirect subsidiary of Lawrence (the "Reorganization"). The effect
of the forward triangular merger has been reflected retroactively in the
accompanying financial statements. In August 1996, the Company completed its
initial public offering of 3,910,000 shares of Class A Common Stock (the "IPO").
 
     Dailey's Restated Certificate of Incorporation provides for three classes
of stock: Class A Common Stock, $.01 par (20,000,000 shares authorized,
4,315,000 issued and outstanding) ("Class A Common Stock"), Class B Common
Stock, $.01 par (10,000,000 shares authorized, 5,000,000 shares issued and
outstanding) ("Class B Common Stock"), and Preferred Stock, $.01 par (5,000,000
shares authorized, none issued or outstanding). The Board of Directors is
empowered to authorize the issuance of Preferred Stock in one or more series and
to fix the rights, powers, preferences and limitations of each series. A holder
of Class B Common Stock may convert its Class B Common Stock into Class A Common
Stock at any time at the ratio of one share of Class A Common Stock for each
share of Class B Common Stock. In the event of liquidation, holders of Class A
Common Stock and Class B Common Stock share with each other on a ratable basis
as a single class in the net assets of the Company available for distribution.
In addition, shares of Class B Common Stock convert automatically into a like
number of shares of Class A Common Stock upon the sale or transfer of such
shares to a person or entity that is not a member of the Lawrence Group (as
defined in the Company's Restated Certificate of Incorporation).
 
     In connection with the IPO, the Company issued 3,910,000 shares of Class A
Common Stock. Net proceeds from the sale of the stock were $27.6 million. The
Company used $5.0 million of the proceeds from the IPO to repay the outstanding
balance of a $10.0 million promissory note, which was incurred in connection
with a dividend declared on June 27, 1996 (the "Dividend"). Prior to
commencement of the IPO, the Company's sole stockholder contributed to the
capital of the Company $5.0 million of the outstanding principal of such note.
The statements of operations for the 1996 fiscal period include pro forma per
share data which gives effect to the number of shares from which proceeds would
have been used to pay the Dividend (an additional 1,250,000 shares assuming a
per share offering price of $8.00, thus earnings per share for the year ended
April 30, 1996, were based on 6,610,000 shares of Common Stock outstanding).
Historical earnings per share excluding the pro forma effect of the dividend was
$0.49 per share for the year ended April 30, 1996.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Principles of Consolidation
 
     The accompanying consolidated financial statements include the accounts of
the Company and its wholly owned subsidiaries. All significant intercompany
transactions and balances are eliminated in consolidation.
 
     The Company has historically had significant transactions with Lawrence and
its affiliates which are reflected in the accompanying financial statements on
the basis established between the Company and Lawrence. See Notes 6, 7, and 10.
 
  Use of Estimates
 
     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.
 
  Cash and Cash Equivalents
 
     The Company considers all investments with a maturity of three months or
less when purchased to be cash and cash equivalents.
 
  Accounts Receivable
 
     Accounts receivable are net of allowances for doubtful accounts of
$1,476,000 in 1997 and $1,325,000 in 1996.
 
  Revenue-Producing Tools and Inventory
 
     Revenue-producing tools and inventory are stated at cost utilizing the
first-in, first-out method. Revenue-producing tools are depreciated on the
straight-line method over their estimated useful lives of 5 to 7 years. Tools
lost in hole and billed to customers and tools abandoned are included in sales
of products and services and the related write-off of the tools' net book values
are included in costs of products and services in the accompanying consolidated
statements of operations.
 
     Tools manufactured and assembled are transferred to revenue-producing tools
as completed at the total cost of components, subassemblies, expendable parts,
direct labor and indirect costs of each tool. For U.S. locations and
international distribution centers, components, subassemblies and expendable
parts are capitalized as inventory and expensed as tools are repaired and
maintained. Components, subassemblies and expendable parts are expensed when
shipped to all international locations other than distribution centers.
 
  Property and Equipment
 
     Property and equipment are stated at cost. Depreciation is calculated
primarily on the straight-line method over the estimated useful lives of 5 to 30
years for buildings and improvements, 3 to 10 years for machinery and equipment,
4 to 10 years for furniture and fixtures and 3 to 7 years for other property and
equipment.
 
     Maintenance and repairs are charged to expense as incurred. Major repairs
and improvements are capitalized and depreciated. The cost and accumulated
depreciation of property and equipment retired or otherwise disposed of are
removed from the related accounts and any gain or loss is recognized in
operations.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- (CONTINUED)
  Intangible Assets
 
     Patents, goodwill and other intangibles are amortized over 13 to 40 years
and had a net book value of $1,384,000 and $287,000 at April 30, 1997 and 1996,
respectively. In March 1997, Dailey acquired certain business assets for $1.6
million including approximately $750,000 of goodwill.
 
  Impairment of Long-Lived Assets
 
     The carrying value of long-lived assets, principally revenue-producing
tools, goodwill and property and equipment, is reviewed for potential impairment
when events or changes in circumstance indicate that the carrying amount of such
assets may not be recoverable. The determination of recoverability is made based
upon the estimated undiscounted future net cash flows of the related asset.
 
  Stock Based Compensation
 
     Statement of Financial Accounting Standards No. 123, "Accounting for
Stock-Based Compensation" ("SFAS 123") establishes alternative methods of
accounting and disclosure for employee stock-based compensation arrangements.
The Company has elected to use the "intrinsic value based method" of accounting
for its stock option plans. This method does not result in the recognition of
compensation expense at the time employee stock options are granted, if the
exercise price of the option equals or exceeds the fair market value of the
stock at the date of grant. (See Note 12).
 
  Income Taxes
 
     The accompanying consolidated financial statements reflect deferred income
taxes on the liability method. Under this method, deferred tax assets and
liabilities are determined based on differences between financial reporting and
tax bases of assets and liabilities and are measured using the enacted tax rates
and laws in effect. An impairment evaluation, with reserves recorded as
necessary for any tax benefit not expected to be realized, is required of
deferred tax assets. A current tax expense or benefit is recognized for
estimated taxes payable or refundable for the current year.
 
     The Company was included in the consolidated U.S. federal income tax return
of Lawrence for taxable periods ending on the closing of the IPO. The Company
and Lawrence are jointly and severally liable with respect to taxes related to
periods prior to the IPO. The Company and its subsidiaries currently file
separate income tax returns. The accompanying consolidated financial statements
reflect the income tax provisions of the Company on a separate return basis for
all years with no U.S. federal tax operating loss, tax credit, or foreign credit
carryforwards generated prior to May 1, 1988 allocated to the Company by
Lawrence.
 
     Pursuant to the Tax Allocation Agreement entered into by the Company and
Lawrence, the Company paid to Lawrence an amount equal to the federal income tax
computed on the Company's (and its subsidiaries) taxable income less any tax
credits generated by the Company or its subsidiaries. The Tax Allocation
Agreement applies to the Company for all years in which the Company (or any
predecessor) is or was included in the Lawrence consolidated federal income tax
return. To the extent a state or other taxing jurisdiction requires or permits a
consolidated, combined or unitary tax return to be filed by Lawrence and its
affiliates and such return includes the Company, the principles expressed with
respect to the consolidated federal tax allocation will apply.
 
  Foreign Currency Translation
 
     The U.S. dollar is the functional currency for all operations. Accordingly,
foreign currency translation gains and losses are recognized in the consolidated
statements of operations.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- (CONTINUED)
  Earnings Per Share
 
     In February 1997, the Financial Accounting Standards Board issued Statement
No. 128, Earnings per Share, which is effective for financial statements issued
for periods ending after December 15, 1997. At such time, the Company will be
required to change the method currently used to compute earnings per share and
to restate all prior periods. Under the new requirements for calculating primary
earnings per share, the dilutive effect of stock options will be excluded. The
method of calculating fully diluted earnings per share will remain unchanged.
The impact of Statement 128 is expected to result in an increase in primary
earnings per share for the year ended April 30, 1997 of $.01 and no change for
the year ended April 30, 1996.
 
  Reclassifications
 
     Certain reclassifications have been made to the 1996 and 1995 financial
statements to conform to the current year presentation.

6. RELATED PARTY TRANSACTIONS
 
     The accompanying consolidated statements of operations include annual
rental charges from Lawrence for a corporate office facility and a manufacturing
and service center facility. See Note 10.
 
     The affiliate balances, other than the amounts included in long-term debt,
are non-interest bearing and have no fixed repayment terms.
 
     The Company provided Lawrence and certain of its affiliates with various
administrative and management services including cash management, accounting,
tax, data processing, human resources and legal services in 1997, 1996 and 1995.
During 1996 and 1995, the Company also utilized from time to time aircraft owned
by a Lawrence subsidiary. Prior to 1997, the Company did not charge Lawrence for
these administrative and management services or reimbursed Lawrence for use of
the aircraft because the effect of not recording the fair values of these
services rendered less services received was not significant. In 1997, the
Company charged Lawrence a net of $68,000 as fair value for these services.
 
     The Company participates in the "Lawrence Companies Retirement Plan", a
defined contribution pension plan, covering all Dailey employees. Contributions
are determined as 50% of the employee's contribution up to 2% of the employee's
total compensation. Amounts charged to pension costs and contributed to the plan
in 1997, 1996 and 1995 totaled $203,000, $178,000 and $152,000, respectively.

7. BORROWING ARRANGEMENTS -- (CONTINUED)
     The note payable to a bank includes, among other things, provisions
relative to maintenance of working capital balances, limitations on additional
borrowing, debt coverage requirements and restrictions on payment of dividends.
The note payable to a bank is collateralized by a majority of the Company's
assets and a portion of other notes payable is collateralized by equipment
purchased.
 
     In conjunction with the $10.0 million note payable to a bank and to limit
interest rate exposure, the Company entered into an interest rate swap, which
converted the floating interest rate to a fixed rate of 7.9% maturing in
December 2000.
 
     Interest paid during the years ended April 30, 1997, 1996 and 1995 amounted
to $858,000, $956,000 and $1,128,000, respectively.
 
     In December 1995, the Company entered into a $3.0 million revolving credit
facility with a bank on December 15, 1995 amended as of June 5, 1996 which
provided interest at the prime rate with an option to convert to a LIBOR-based
rate plus 2.0%. In December 1996, this revolving credit facility was extended
through December 1997. At April 30, 1997, the Company had no outstanding
borrowings. The obligations of the Company to the bank are collateralized by
substantially all of the Company's property, equipment, inventory, intellectual
property and receivables. The credit facility contains certain restrictive
covenants and customary events of default and conditions to the bank's
obligation to make advances to the Company.
 
     On June 20, 1997, the note payable to a bank was amended to increase the
outstanding principal balance of the term loan to $41.5 million and the
outstanding principal balance of advances made pursuant to the revolving line of
credit to $4.0 million. Principal payments on the term loan are $350,000
quarterly through July 1998, with increasing payments thereafter until maturity
on June 30, 2002, at which time the obligation of the bank to make revolving
credit advances also terminates. Interest on the term loan and revolving credit
advances is variable and will fluctuate at a variable margin over the bank's
prime rate or at a LIBOR-based rate. Both interest rates can fluctuate based on
leverage ratios. On June 23, 1997, the date of funding, the average interest
rate on revolving advances was 8.0%. Borrowings under the revolving credit
facility are limited to the lesser of $15.0 million or a loan formula based upon
the receivable level of eligible accounts receivable. The note payable to the
bank contains certain restrictive covenants and customary events of default and
conditions to the bank's obligation to make advances.

     For income tax reporting at April 30, 1997 the Company has foreign tax
credit carryforwards of approximately $1,661,000, which will begin to expire in
the fiscal year ending April 30, 2000. The valuation allowance relates to
deferred tax assets established for the net operating loss, provision for
doubtful accounts receivable and foreign tax credit carryforward. No other
valuation allowances were considered necessary. The change in the valuation
allowance is due to the utilization of prior year net operating loss
carryforward and the establishment of an allowance for foreign tax credit
carryforwards. Based on the earnings history, it is expected that future taxable
income will be more than sufficient to utilize the remaining deductible
temporary differences.
 
     No provision is made for U.S. income and foreign withholding taxes
applicable to undistributed earnings of foreign subsidiaries that are
indefinitely reinvested in foreign operations.
 
     Income taxes paid during 1997, 1996 and 1995 were $608,000, $538,000 and
$917,000, respectively.

9. ROYALTIES
 
     In 1986, the Company purchased the design, patents and rights to certain
hydraulic tools and entered into a royalty agreement with the seller which
expires in 1999 and 2003 as to the covered hydraulic drilling and fishing jars,
respectively. Royalty agreements were executed between the Company and the
royalty owner in 1993 and 1994 on newly issued methods and apparatus patents
related to a double-acting drilling accelerator and improvements to hydraulic
drilling jars. In March 1994, the royalty agreements were amended to cap
royalties at 5.0% of annual net rental revenues derived from the hydraulic
drilling and fishing jars and double-acting drilling accelerators through
December 1999, with the royalty percentage decreasing to 4.0% from January 2000
to expiration of the applicable patents. Upon expiration of the patents, no
royalties will be required. The amended agreement also revised the 1.0% royalty
paid on net lost-in-hole revenue for the original hydraulic drilling jar patent
to the 2.0% provided in subsequent royalty agreements. For the years ended April
30, 1997, 1996 and 1995, the accompanying consolidated statements of operations
include royalty expense of $879,000, $843,000 and $826,000, respectively,
excluding the $250,000 related to the amended royalty agreement. The owner of
the royalty was an officer of the Company until October 1994.
 
10. COMMITMENTS AND CONTINGENCIES
 
     The Company leases office space, transportation equipment and other

     Rental expense under operating leases with third parties, inclusive of
month-to-month rentals, totaled $2,184,000, $2,436,000 and $1,700,000 in 1997,
1996 and 1995, respectively, and with Lawrence totaled $915,000, $1,306,000 and
$1,244,000 in 1997, 1996 and 1995, respectively and are included in selling
general and administrative expenses and cost of rentals.
 
     The Company is the defendant in various legal proceedings and claims which
arise in the ordinary course of its business. In the opinion of management, the
amount of ultimate liability with respect to these actions will not materially
affect the consolidated financial statements of the Company. The Company is also
the plaintiff in certain actions defending its patents and proprietary designs.
 
11. CONCENTRATIONS OF CREDIT RISK AND FAIR VALUES OF FINANCIAL INSTRUMENTS
 
     The Company is subject to credit risk and other risks inherent in
international operations. Generally, in excess of 50% of the Company's
receivables are due from oil and gas exploration companies and drilling
contractors operating in countries other than the United States and from the
Company's international agents. United States receivables are generally due from
major oil and gas exploration and drilling contractors throughout the oil field
areas of the United States. The Company routinely monitors its cash and
receivable positions with customers and international agents.

11. CONCENTRATIONS OF CREDIT RISK AND FAIR VALUES OF FINANCIAL
INSTRUMENTS -- (CONTINUED)
     The following methods and assumptions were used by the Company in
estimating its fair value disclosures for financial instruments:
 
     Cash and cash equivalents: The carrying amount reported in the balance
sheet for cash and cash equivalents approximates its fair value.
 
     Long- and short-term debt and interest rate swap: The carrying amount of
the Company's borrowings under its short-term revolving note payable
approximates fair value. The fair values of the Company's long-term debt and
interest rate swap are estimated using discounted cash flow analyses, based on
the Company's current incremental borrowing rates for similar types of borrowing
arrangements. The carrying amounts of the Company's long-term debt approximated
the fair values at April 30, 1997 and 1996.
 
12. STOCK OPTIONS AND AWARDS
 
     Prior to the IPO, the Company established its 1996 Key Employee Stock Plan
(the "1996 Plan") and its 1996 Non-Employee Director Stock Option Plan (the
"1996 Director Plan"). The 1996 Plan and the 1996 Director Plan (the "Plans")
have 900,000 shares authorized for the granting of options or restricted stock
to management personnel and 100,000 shares authorized for the granting of
options to directors, respectively.
 
     The Company applied Accounting Principals Board Opinion 25 ("APB25") and
related interpretations in accounting for these plans. Accordingly, no
compensation cost has been recognized in 1997 for either plan. Based on
information available at the grant date, the Company estimated a four year
expected life for all options granted during the year, volatility of .53 and
risk free interest rates ranging from 6.03% to 6.70%. The Company does not
presently anticipate issuing dividends in the future. Had compensation cost for
the Company's two stock-based compensation plans been determined based on the
fair value at the grant dates for awards under those plans consistent with the
method available under SFAS 123, the Company's net income and earnings per share
for 1997 would have been reduced to the pro forma amounts listed below. There
were no options issued in 1996 or 1995.

have an exercisable life between one and five years from the date of grant. Of
the 534,129 options outstanding at April 30, 1997, 374,124 were exercisable.
 
     Immediately following the IPO, restricted stock awards totaling 360,000 of
Class A Common Stock were granted to key officers. In October 1996, a restricted
stock award of 45,000 Class A Common Stock was granted to an executive officer.
Awards do not require any payment by the executive officers and were to vest
over a three year period. Subsequently, the Board approved accelerated vesting
of the 405,000 shares of restricted stock awards which resulted in the Company
recognizing $2.8 million in non-cash compensation expense during 1997.
Restricted stock activity for the year ended April 30, 1997 was as follows:

13. SUBSEQUENT EVENTS
 
     On June 20, 1997, the Company consummated the acquisition (the "ADI
Acquisition") of Air Drilling International, Inc. ("ADI"). Dailey acquired ADI
for $46.4 million, including the repayment of approximately $16.8 million in
indebtedness. As a result of the ADI Acquisition, the Company became a leading
worldwide provider of air drilling services for underbalanced drilling
applications.
 
     In June 1997, following the ADI Acquisition, the Company implemented a cost
reduction program to flatten its corporate management structure and streamline
the Company's operations (the "Management Reorganization"). As a result of such
program, the Company expects to incur a $2.8 million restructuring charge during
the first quarter of the year ended April 30, 1998 associated primarily with
staff reductions and severance settlements and various reorganization costs. The
Company expects the Management Reorganization to result in annual savings of
approximately $1.8 million. The Company is contemplating the private placement
of $100 million of senior unsecured notes during the year ended April 30, 1998.
It is anticipated the

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)
 
1. BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES
 
     The accompanying unaudited consolidated financial statements include the
accounts of Dailey International Inc. and its subsidiaries and predecessors
("Dailey" or the "Company") and have been prepared in accordance with United
States generally accepted accounting principles for interim financial
information and with the instructions to Form 10-Q and Article 10 of Regulation
S-X. Accordingly, they do not include all of the information and footnotes
required by generally accepted accounting principles for complete financial
statements. In the opinion of management, all adjustments considered necessary
for a fair presentation have been included. Operating results for the three and
six month periods ended October 31, 1997 are not necessarily indicative of the
results that may be expected for the fiscal period. For further information,
reference is made to the consolidated financial statements and footnotes thereto
included in the Company's Form 10-K filed with the Securities and Exchange
Commission on July 29, 1997. Certain reclassifications have been made to the
April 30, 1997 and October 31, 1996 financial information to conform to the
current period presentation.
 
2. ORGANIZATION AND PUBLIC OFFERING
 
     The accompanying consolidated financial statements reflect the operations
of Dailey International Inc. (formerly Dailey Petroleum Services Corp.), a
Delaware corporation. In June 1996, Dailey Petroleum Services Corp. was merged
with Dailey Corporation which was named Dailey Petroleum Services Corp. On
October 7, 1997, the Company changed its name to Dailey International Inc. In
July 1997, the Company's Board of Directors changed the Company's fiscal year to
December 31, effective December 31, 1997.
 
     The Company is a leading provider of specialty drilling services to the oil
and gas industry and designs, manufactures and rents technologically-advanced
downhole tools for oil and gas drilling and workover applications. Founded in
1945 as a rental tool company, Dailey began offering directional drilling
services in 1984 and currently provides such services in the Gulf of Mexico, the
U.S. Gulf Coast region and, most recently, Venezuela. In June 1997, the Company
acquired (the "ADI Acquisition") Air Drilling International, Inc. ("ADI") and,
as a result, became a leading provider worldwide of air drilling services for
underbalanced drilling applications. The Company operates in one business
segment.
 
     Prior to June 1996, Dailey was a wholly-owned subsidiary of Lawrence
Industries, Inc. ("Lawrence"). In June 1996, in preparation for the initial
public offering of Class A Common Stock of Dailey, Lawrence reorganized its
ownership of the Company into a holding company structure through a forward
triangular merger of Dailey Petroleum Services Corp., into a newly-formed,
wholly-owned indirect subsidiary of Lawrence, Dailey Corporation (the
"Reorganization"), which is now Dailey International Inc. The effect of the
forward triangular merger has been reflected retroactively in the accompanying
financial statements. In August 1996, the Company completed its initial public
offering of 3,910,000 shares of Class A Common Stock (the "1996 IPO").
 
     Dailey's Restated Certificate of Incorporation provides for three classes
of stock: Class A Common Stock, $.01 par (20,000,000 shares authorized,
4,627,598 issued and 4,483,598 outstanding) ("Class A Common Stock"), Class B
Common Stock, $.01 par (10,000,000 shares authorized, 5,000,000 shares issued
and outstanding) ("Class B Common Stock"), and Preferred Stock, $.01 par
(5,000,000 shares authorized, none issued or outstanding). The Board of
Directors is empowered to authorize the issuance of Preferred Stock in one or
more series and to fix the rights, powers, preferences and limitations of each
series. A holder of Class B Common Stock may convert its Class B Common Stock
into Class A Common Stock at any time at the ratio of one share of Class A
Common Stock for each share of Class B Common Stock. In the event of
liquidation, holders of Class A Common Stock and Class B Common Stock share with
each other on a ratable basis as a single class in the net assets of the Company
available for distribution. In addition, shares of Class B Common Stock convert
automatically into a like number of shares of Class A Common Stock upon the sale
or

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
transfer of such shares to a person or entity that is not a member of the
Lawrence Group (as defined in the Company's Restated Certificate of
Incorporation).
 
     In connection with the 1996 IPO, the Company issued 3,910,000 shares of
Class A Common Stock. Net proceeds from the sale of the stock were $27.6
million. The Company used $5.0 million of the proceeds from the 1996 IPO to
repay the outstanding balance of a $10.0 million promissory note, which was
incurred in connection with a dividend declared on June 27, 1996 (the
"Dividend"). Prior to commencement of the 1996 IPO, the Company's sole
stockholder contributed to the capital of the Company $5.0 million of the
principal of such note.
 
3. ADI ACQUISITION
 
     On June 20, 1997, the Company purchased the stock of ADI (a provider of air
drilling services for underbalanced drilling applications) for $46.4 million,
including the repayment of approximately $16.8 million of ADI indebtedness,
financed with bank debt of $45.5 million and proceeds from the 1996 IPO. The ADI
Acquisition was accounted for under the purchase method of accounting. As a
result, the assets and liabilities of ADI were recorded at their estimated fair
market values as of the date of the ADI Acquisition. The Company recorded
goodwill of approximately $22.3 million relating to the excess of the fair
market value of ADI's assets over the purchase price paid for ADI, which will be
amortized over 20 years and result in approximately $1.1 million in amortization
expense per year. Since the goodwill associated with the ADI Acquisition will
not be amortized for tax purposes, the Company expects its effective tax rate
shown on its financial statements to increase significantly as a result of the
ADI Acquisition. The purchase price allocation was based on preliminary
estimates and may be revised at a later date.
 
     The pro forma unaudited results of operations for the three and six months
ended October 31, 1997 and 1996, assuming consummation of the purchase of ADI as
of May 1, 1996 utilizing interim financing of $45.5 million under the Company's
bank credit facility and reflecting extinguishment of debt of Dailey and ADI
(except for capitalized leases), are as follows:

     The pro forma information for the three and six months ended October 31,
1997 and 1996, includes adjustments for additional depreciation and amortization
expense associated with the purchase price allocation using a 20-year life for
goodwill and an average life of eight years for fixed assets, increased interest
expense for the additional borrowings under the credit facility as if they were
incurred at the beginning of the period and related adjustments for income
taxes. The pro forma information is not necessarily indicative of the results of
operations had the acquisition been affected on the assumed dates or the results
of operations for any future period.

5. STOCK OPTIONS AND AWARDS
 
     Prior to the 1996 IPO, the Company established its 1996 Key Employee Stock

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Shareholders of
Air Drilling International, Inc.:
 
     We have audited the accompanying consolidated balance sheets of Air
Drilling International, Inc. (the "Company") and subsidiaries as of December 31,
1996 and 1995, and the related consolidated statements of operations,
stockholders' equity and cash flows for the year ended December 31, 1996 and the
period from May 19, 1995 (Inception) to December 31, 1995. These consolidated
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these consolidated 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 consolidated financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the consolidated financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
Air Drilling International, Inc. as of December 31, 1996 and 1995, and the
consolidated results of its operations and its cash flows for the year ended
December 31, 1996 and the period from May 19, 1995 (Inception) to December 31,
1995, in conformity with generally accepted accounting principles.

                        AIR DRILLING INTERNATIONAL, INC.
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
1. BASIS OF PRESENTATION:
 
     The accompanying consolidated financial statements include the accounts of
Air Drilling International, Inc. ("ADI") and its wholly owned subsidiaries: Air
Drilling Services, Inc., which includes Air Drilling Services de Venezuela, C.A.
("ADS"), Air Drilling Services France (SARL) ("ADS France"), Canadian Air
Drilling Services Ltd. ("CADS") and Specialty Testing & Consulting Ltd.
("Specialty"), collectively (the "Company"). ADS is located in the United
States. CADS and Specialty are located in Canada. All intercompany balances have
been eliminated.
 
     Effective May 19, 1995, ADI acquired ADS, CADS and Specialty. ADI is 85%
owned by Wind River Associates LLC ("Wind River") and 15% by prior management.
Wind River paid $10,500,000 to acquire the 85% interest. The acquisition was
accounted for using the purchase method of accounting. The purchase price was
allocated based on the relative fair market value of the acquired assets and
assumed liabilities.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
  General:
 
     ADI's principal business is to provide air drilling services and rental of
related equipment to companies in the oil and gas industry on a domestic and
international basis.
 
  Use of Estimates in the Preparation of 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.
 
  Property and Equipment:
 
     Property and equipment are stated at cost. Maintenance and repair costs are
expensed as incurred; renewals and betterments are capitalized. Depreciation is
provided for at rates based upon estimated useful service, on a straight-line
and accelerated basis ranging from 5 to 10 years. Upon sale or retirement, the
asset cost and accumulated depreciation are removed from the accounts and any
resulting gain or loss is reflected in operations.
 
  Materials and Supplies Inventory:
 
     Inventories consist of operating materials and supplies used to support the
machinery and equipment. Due to the nature of ADI's operations, the length of
various contracts and the international location of several jobs, inventories
are classified as long term assets because these materials and supplies may be
used over a period longer than one year. Inventories are carried at cost.
 
  Income Taxes:
 
     ADS files a consolidated tax return with ADI in the United States. CADS and
Specialty file separate tax returns in Canada. Income taxes are calculated
pursuant to Statement of Financial Accounting Standards No. 109, Accounting For
Income Taxes. Under this method, income taxes are recorded for future events at
tax rates in effect when the balances are expected to be paid. The Company
intends on indefinitely reinvesting its earnings in CADS and Specialty.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
  Revenue Recognition:
 
     ADI recognizes revenue as services are performed; potential contract losses
are recorded in the period known.
 
  Loss Per Share:
 
     Loss per share is calculated by taking the net loss divided by the weighted
average common shares outstanding. The common stock warrant is not included
since it would be antidilutive.
 
     In 1997, FASB Statement No. 128 Earnings Per Share was issued. The Company
believes the implementation of this statement will have an immaterial impact on
earnings per share.
 
  Foreign Currency Translation:
 
     Canadian and French assets and liabilities are translated into U.S. dollars
using the exchange rate in effect at year end. Canadian and French revenues and
expenses are translated using average exchange rates for each period.
Adjustments resulting from these translations are accumulated in a separate
component of stockholders' equity. Foreign currency transaction gains or losses,
which primarily represent exchange gains or losses resulting from the
denomination of current intercompany balances into U.S. dollars, are included in
determining net income for the period.
 
  Cash and Cash Equivalents:
 
     ADI considers cash on hand, deposits in bank and certificates of deposit
with original maturities of less than three months to be cash equivalents.
 
     Under the terms of a service agreement, ADS was obligated to maintain a
$112,500 letter of credit. The funds in this restricted account served as a
guarantee of completion and are included in a certificate of deposit on the
consolidated balance sheet. This amount was released in 1996.
 
  Debt Issuance Costs:
 
     Debt issuance costs are being amortized over the term of the related
indebtedness using the effective interest method.
 
  Debt Discount:
 
     The debt discount is being amortized over the term of the related
indebtedness using the effective interest method.
 
  Supplemental Cash Flow Disclosures:
 
     During fiscal year 1996, the Company had noncash capital lease property and
equipment additions of $904,433.

     On December 31, 1996, the Company entered into a new debt agreement to
replace its existing Revolving Line and Term Notes. The new agreement provides
for a Reducing Term Note of $8.5 million, subordinated debt of $4.0 million and
the issuance of preferred stock for $1.5 million. The debt was funded on January
2, 1997 and the old Revolving Line and Term Notes were paid off. Because the
Company had a binding contract to repay the old debt at December 31, 1996, all
costs associated with the old debt have been charged to operations during 1996.
In addition, the classification of debt between current and long-term at
December 31, 1996 has been based on the terms of the new debt. In connection
with the refinancing, ADI issued detachable warrants for up to 35% of the
Company, initially valued by management at $1.15 million. Under the new
agreement, the Company was in violation of the covenant to deliver financial
statements within 90 days of year end and received a waiver for this violation.

     The Revolving Note and Term Note agreements require that, among other
items, certain financial covenants be met, including tangible net worth,
operating and net cash flow, debt coverage, operating profit and collateral
coverage ratio. The loan agreements also restrict the payment of dividends. The
Revolving Note and Term Note agreements contain a provision that if there is any
material adverse change in the Company's financial condition, the lender has the
right to declare the Company in default.
 
     The fair value of the long-term debt as of December 31, 1996 and 1995 was
determined using valuation techniques that are considered management's best
estimate based on the current market. The carrying amount of the debt
approximated market value as of December 31, 1996. The carrying amount of the
debt exceeded the market value by approximately $221,000 as of December 31,
1995.

8. DEFINED CONTRIBUTION PLAN:
 
     All ADS employees are eligible to participate in a defined contribution
plan (401k) whereby employees can make voluntary contributions for a portion of
their compensation. The Company matches a discretionary percentage of the
employees' contributions. For the year ended December 31, 1996 and the period
from May 19, 1995 (inception) to December 31, 1995, ADS contributed
approximately $13,300 and $8,000, respectively.

9. STOCKHOLDERS' EQUITY:
 
     In connection with the acquisition of ADS, CADS and Specialty, ADI issued
debt with detachable warrants to purchase 25,000 shares of ADI common stock at
any time at the stated par value at $.01 per share, representing 20% of the
common stock of ADI, after dilution for these new shares.
 
     The holder of the warrants has the ability to put the warrants back to ADI
for an agreed-upon price based upon the fair market value of the Company after
three years. Additionally, after five years, ADI can call the warrants and pay
the holder an agreed-upon price based upon the fair market value of the Company.
 
     At the inception of ADI's operations, the Company recorded the long-term
debt at the face value, less the fair market value of $600,000 of the warrants.
Changes in valuation of the warrants are amortized to accumulated deficit over
the remaining term of the warrants. Management has estimated the fair market
value of the put warrants as of December 31, 1996 and 1995 to be $113,898 and
$75,000, respectively. The $113,898 was paid by the Company on January 2, 1997
and, as noted in Note 4, the Company issued new detachable warrants to purchase
up to 35% of the Company.
 
     As of December 31, 1996, ADS had authorized 660,000 shares of preferred
stock and no shares were outstanding.
 
10. CONTRACTS:
 
     Specialty is a party to a contract with Global Air Drilling Services, Inc.
("Global") in which Global uses Specialty's equipment and in return receives 98%
of Global's before-tax profits. Specialty may terminate the contract at any
time. For the year ended December 31, 1996 and the period from May 19, 1995
(inception) to December 31, 1995, Specialty collected $87,000 and $353,000,
respectively, from Global.
 
11. CONCENTRATION OF CREDIT RISK:
 
     Certain locations where ADI operates may have unstable political and
economic environments. The Company has purchased foreign credit insurance
(subject to a $200,000 deductible on all receivables at December 31, 1996) on
those receivables due from companies operating in foreign countries. Foreign
receivables not insured at December 31, 1996 and 1995 were $215,000 and
$367,000, respectively. At various times throughout the year, the Company
maintains cash and certificate of deposit balances in excess of the federally
insured limit.

To the Shareholders of
Air Drilling International, Inc.:
 
     Our audit was conducted for the purpose of forming an opinion on the basic
consolidated financial statements of Air Drilling International, Inc. taken as a
whole. The supplemental schedules on pages F-61 through F-66 are presented for
the purposes of additional analysis and are not a required part of the basic
consolidated financial statements. Such information has been subjected to the
auditing procedures applied in the audit of the basic consolidated financial
statements and, in our opinion, is fairly stated, in all material respects, in
relation to the basic consolidated financial statements taken as a whole.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Shareholders of Air Drilling Services, Inc.
Canadian Air Drilling Services Ltd.,
Specialty Testing & Consulting Ltd. and
Global Air Drilling Services Ltd.:
 
     We have audited the accompanying combined balance sheet of Air Drilling
Services, Inc., Canadian Air Drilling Services Ltd., Specialty Testing &
Consulting Ltd. and Global Air Drilling Services Ltd. as of May 18, 1995, and
the related combined statements of income, stockholders' equity and cash flows
for the period from January 1, 1995 through May 18, 1995. These financial
statements are the responsibility of the Companies' management. Our
responsibility is to express an opinion on these financial statements based on
our audits. We did not audit the financial statements of Canadian Air Drilling
Services Ltd. as of May 18, 1995 or for the period from January 1, 1995 through
May 18, 1995. Those statements reflect total assets of $5,775,350 as of May 18,
1995, and total revenues of $2,798,517 for the period from January 1, 1995
through May 18, 1995. Those financial statements were audited and reported on
separately by other auditors.
 
     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 and the report of the other auditors provide a
reasonable basis for our opinion.
 
     In our opinion, based on our audits and the report of the other auditors,
the combined financial statements referred to above present fairly, in all
material respects, the combined financial position of Air Drilling Services,
Inc., Canadian Air Drilling Services Ltd., Specialty Testing & Consulting Ltd.
and Global Air Drilling Services Ltd. as of May 18, 1995, and the combined
results of their operations and their cash flows for the period from January 1,
1995 through May 18, 1995, in conformity with generally accepted accounting
principles in the United States.

 9. CONCENTRATION OF CREDIT RISK:
 
    Approximately 76% of ADS' revenue is from international operations. Some of
    these locations may have unstable political and economic environments. At
    May 18, 1995, approximately $1,700,000 of accounts receivable was due from
    companies operating in foreign countries.
 
    Approximately 11% of CADS' revenue is from international operations. At May
    18, 1995, approximately $83,300 of accounts receivable was due from
    companies operating in foreign countries.
 
    Specialty/Global did not generate any revenue from international operations
    during the period from January 1, 1995 through May 18, 1995.
 
10. CADS CONTINGENT LIABILITIES:
 
    In prior years, investment tax credits of $147,000 were claimed as a
    reduction of federal taxes payable for Canadian tax purposes. This amount is
    potentially repayable in the event that the related equipment has not been
    used "primarily in Canada." The equipment had previously been used in
    Venezuela; however, the majority of it is currently being used in Canada.
    While the location of its future use is intended to be in Canada, it is
    possible this may not transpire. The actual use test used by Revenue Canada
    will be a matter of fact. The amount of any repayment that may result is
    undeterminable at this time. Any potential repayment will likely be recorded
    as a charge to the income statement in the period in which it is paid.

              NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS
                                 APRIL 30, 1997
 
1. BASIS OF PRESENTATION:
 
     The accompanying unaudited consolidated financial statements include the
accounts of Air Drilling International, Inc. ("ADI") and its wholly owned
subsidiaries: Air Drilling Services, Inc., which includes Air Drilling Services
de Venezuela, C.A. ("ADS"), Air Drilling Services France (SARL) ("ADS France"),
Canadian Air Drilling Services Ltd. ("CADS") and Specialty Testing & Consulting
Ltd. ("Specialty"), collectively (the "Company"). ADS is located in the United
States. CADS and Specialty are located in Canada. All intercompany balances have
been eliminated. The financial statements have been prepared in accordance with
United States generally accepted accounting principles for interim financial
information. Accordingly, they do not include all of the information and
footnotes required by generally accepted accounting principles for complete
financial statements. In the opinion of management, all adjustments considered
necessary for a fair presentation have been included. Operating results for the
four month period ended April 30, 1997 are not necessarily indicative of the
results that may be expected for the year ended December 31, 1997.
 
2. NOTES PAYABLE:
 
     On December 31, 1996, the Company entered into a new debt agreement to
replace its existing Revolving Line and Term Notes. The new agreement provides
for a Reducing Term Note of $8.5 million, subordinated debt of $4.0 million and
the issuance of preferred stock for $1.5 million. The debt was funded on January
2, 1997 and the old Revolving Line and Term Notes were paid off. Because the
Company had a binding contract to repay the old debt at December 31, 1996, all
costs associated with the old debt were charged to operations during 1996. In
addition, the classification of debt between current and long-term at December
31, 1996 was based on the terms of the new debt. In connection with the
refinancing, ADI issued detachable warrants for up to 35% of the Company,
initially valued by management of $1.15 million.
 
     The Company had notes payable at April 30, 1997 and December 31, 1996 that
consisted of the following:

The Board of Directors and Shareholders
Directional Wireline Services, Inc.,

     We have audited the accompanying combined balance sheets of Directional
Wireline Services, Inc., DAMCO Services, Inc. and DAMCO Tong Services, Inc.
(collectively, "DWS/DAMCO" -- see Note 1) as of September 30, 1997 and December
31, 1996, and the related combined statements of operations, shareholders'
equity, and cash flows for the nine-month period ended September 30, 1997 and
the years ended December 31, 1996 and 1995. These financial statements are the
responsibility of DWS/DAMCO'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 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

                               SEPTEMBER 30, 1997
 
1. ORGANIZATION AND BASIS OF PRESENTATION
 
     The combined financial statements include the accounts of Directional
Wireline Services, Inc. ("DWS"), DAMCO Services, Inc. and DAMCO Tong Services,
Inc., hereinafter collectively referred to as "DWS/DAMCO". All significant
intercompany transactions and balances have been eliminated in the combined
financial statements.
 
     DAMCO Services, Inc. was organized in 1968 and began operations in 1969 as
DAMCO Testers, Inc. In 1980, this company was reorganized and, in 1992, its name
was formally changed to DAMCO Services, Inc. DAMCO Tong Services, Inc. began
operations in 1982. DWS was founded in 1973 and also reorganized in 1980.
DWS/DAMCO are under common ownership control and management.
 
     In November 1997, DWS/DAMCO entered into an agreement with Dailey to sell
the operating assets and liabilities of DWS/DAMCO. On January 28, 1998, the
operating assets and liabilities of DWS/DAMCO were acquired for approximately
$61 million in cash by Dailey, subject to a working capital adjustment.
 
     DWS/DAMCO are leading providers of electric wireline and tubing conveyed
perforating services and tubular testing and handling services to the offshore
and onshore oil and gas industry in the U.S. Gulf of Mexico region and Nigeria.
The electric wireline services are utilized in both the exploration and
production phases of an oil and gas well and include pipe recovery, cased hole
logging, electric line perforating services and other cased hole services such
as installation of bridge plugs, packers, retainers, pressure control equipment
and thru-tubing bridge plugs. The tubular testing services consist of
hydrostatic and gas pressure testing services that detect leaks and flaws in
tubulars as they are run into the wellbore. The tubular handling services
include assembling production pipe and tubing, dual completion strings, premium
threaded connections and ultra-high torque tubulars.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that effect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
  Cash and Cash Equivalents
 
     DWS/DAMCO consider all investments with a maturity of three months or less
when purchased to be cash and cash equivalents.
 
  Consumable Supplies Inventories
 
     Consumable supplies inventories, consisting primarily of engineering
supplies and explosives, are valued using the first-in, first-out method and are
carried at the lower of cost or market.
 
  Revenue-Producing Tools and Property and Equipment
 
     Revenue-producing tools and property and equipment are stated at cost.
Depreciation is calculated on the straight-line method over the estimated useful
lives of less than 39 years for buildings and improvements, three to five years
for furniture and fixtures, seven years for revenue-producing tools and five
years for vehicles. Maintenance and repairs are charged to expense as incurred.
Major repairs and improvements are capitalized and depreciated. The cost and
accumulated depreciation of property and equipment retired or otherwise disposed
of are removed from the related accounts. Tools manufactured and assembled are
transferred to

revenue-producing tools as completed at the total cost of components,
subassemblies, expendable parts, direct labor costs of each tool.
 
  Impairment of Long-Lived Assets
 
     The carrying value of long-lived assets, principally revenue-producing
tools and property and equipment, is reviewed for potential impairment when
events or changes indicate that the carrying amount of such assets may not be
recoverable. The determination of recoverability is made based upon the
estimated undiscounted future net cash flows of the related asset.
 
  Revenue Recognition
 
     Revenue is recognized as services are performed or equipment is provided in
accordance with contractual provisions.
 
  Foreign Currency Translation
 
     The U.S. dollar is the functional currency for all operations. Accordingly,
foreign currency translation gains and losses are recognized in the combined
statement of operations. Such gains and losses were not significant for any of
the periods presented. DWS/DAMCO do not enter into any transactions with
derivative instruments.
 
  Income Taxes
 
     DWS/DAMCO have elected S corporation status for federal and state income
tax purposes; accordingly, income taxes are the responsibility of the
shareholders of DWS/DAMCO.

5. SETTLEMENT OF SHAREHOLDER LITIGATION
 
     Effective January 1, 1995, DWS/DAMCO settled litigation with the spouse of
a deceased shareholder by making a cash payment of $482,660 and repurchasing the
deceased shareholder's stock for an additional $1,954,340. Also in 1995,
unrelated to the shareholder litigation, DWS/DAMCO repurchased additional
outstanding shares for $69,155. The treasury stock resulting from these
transactions, together with previously unissued stock, was thereafter awarded as
stock bonuses, which were recorded as $2,038,421 of non-cash compensation
expense in 1995.
 
6. RELATED PARTY TRANSACTIONS
 
     Management fees for certain accounting and administrative services are paid
to an affiliated company owned by the majority shareholder. DWS/DAMCO paid
management fees totaling $122,389 for the nine-month period ended September 30,
1997, and $150,000 for each of the fiscal years ended December 31, 1996 and
1995, which management believes reasonably approximates the value of the related
services rendered.
 
     DWS/DAMCO purchased vehicles from an affiliated company owned by the
majority shareholder. Purchases totaled $334,205 for the nine-month period ended
September 30, 1997 and $368,948 and $381,155 for the fiscal years ended December
31, 1996 and 1995, respectively. In addition, DWS/DAMCO are parties to lease
agreements with an affiliated company as previously described.
 
     In 1991, DWS was assigned all rights, title, and interest in a patent
developed by a shareholder. In exchange for the assignment of the patent, DWS
was required to pay to a company under common ownership of DWS 35% of the
revenues attributable to the actual use of the patent. For the fiscal years
ended December 31, 1996 and 1995, DWS recorded royalty fees totaling $101,955
and $155,780, respectively. In January 1997, DWS paid $350,000, including
$115,437 of accrued royalty fees at December 31, 1996, to settle the royalty
agreement.
 
7. EMPLOYEE BENEFITS
 
  Profit Sharing Plan
 
     Substantially all employees with one year of service with DWS/DAMCO and who
have worked at least 1,000 hours during the year are eligible to participate in
DWS/DAMCO's defined contribution profit sharing plans. Participants may
contribute up to 5% of their annual compensation for which DWS/DAMCO match

the contribution 100%. Benefit costs recognized as expense under these plans
were $225,404 for the nine-month period ended September 30, 1997, and $248,706
and $197,480 for the fiscal years ended December 31, 1996 and 1995,
respectively.
 
  Postretirement Health Care Benefits
 
     DSI offers postretirement health care benefits to two retired employees and
their spouses. This plan does not cover any active personnel or other retirees.
At September 30, 1997 and December 31, 1996, the accrued postretirement benefit
costs included accumulated postretirement benefit obligations for retirees of
$86,369 and $88,761, respectively. For the nine months ending September 30, 1997
and fiscal years ending December 31, 1996 and 1995, net periodic postretirement
benefit costs included interest costs of $4,776, $6,584, and $6,815,
respectively.
 
     The postretirement health care benefits consist solely of the payment of
supplemental medical insurance. For measurement purposes, contractual payments
for these health care benefits were used to determine net periodic
postretirement benefit costs.
 
8. CONCENTRATIONS OF CREDIT RISK AND FAIR VALUES OF FINANCIAL INSTRUMENTS
 
     DWS/DAMCO are subject to credit risk and other risks inherent in
international operations. Substantially all of DWS/DAMCO accounts receivable are
due from oil and gas exploration companies and drilling contractors located
primarily in south Texas and the Gulf of Mexico. DWS/DAMCO perform periodic
credit evaluations of their customers' financial condition and generally do not
require collateral.
 
     The following methods and assumptions were used by DWS/DAMCO in estimating
their fair value disclosures for financial instruments.
 
          Cash and Cash Equivalents: The carrying amount reported in the balance
     sheet for cash and cash equivalents approximates its fair value.
 
          Notes Payable to Affiliated Companies and Other Notes Payable: The
     carrying amount of the Combined Entities' borrowings under these notes
     approximates fair value as all note terms are within 36 months.
