                                     PART I

ITEM 1. BUSINESS AND PROPERTIES


GENERAL

     Dailey International Inc. ("Dailey" or 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 Services Limited
("IDS" and the "IDS Acquisition"), a specialized provider of directional
drilling services, and in January 1998, the Company acquired substantially all
of the operating assets and liabilities of Directional Wireline Services, Inc.,
DAMCO Services, Inc. and DAMCO Tong Services, Inc. (collectively "DWS/DAMCO" and
the "DWS/DAMCO Acquisition"), 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 that the acquisition of IDS provides it with key
directional drilling technologies, including a resistivity tool for logging
while drilling, which will allow the company to provide a more fully integrated
package of directional drilling services. 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 company based in the United Kingdom
         which manufactures directional drilling tools, for $9.4 million in cash
         and 1,064,600 shares of Class A Common Stock, plus assumption or
         repayment of debt of approximately $10.6 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 substantially all 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 (the "ADI Acquisition") for
         $46.4 million, including the repayment of approximately $16.8 million
         of indebtedness.

                                       3
<PAGE>   4

         - 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.

         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, 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 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.


         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


                                       4
<PAGE>   5
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. 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 tubing conveyed perforation ("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. Operators
contract tubular testing services 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. Mistakes in torquing tubulars can be costly in terms
of downtime and damaged equipment; 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 currently the leading supplier of drilling jars to the
rental tool market worldwide.

         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 



                                       5
<PAGE>   6

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 42%, 39% and 52% of total revenues for fiscal 1996 and 1997 and
the eight months ended December 31, 1997, respectively. As of January 31, 1998,
Dailey had operations in approximately 39 foreign countries. See Note 17 of the
Notes to Consolidated Financial Statements of Dailey contained elsewhere in this
Form 10-K 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 



                                       6
<PAGE>   7

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 (including Canada) 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 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.

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.



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 


                                       7
<PAGE>   8

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.

         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.

INTELLECTUAL PROPERTY

         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.

         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.
In addition, pursuant to the DWS/DAMCO Acquisition and IDS Acquisition, the
Company acquired additional key patents relating to its TCP services and
directional drilling services. 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. 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.

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.

         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.

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.

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 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.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND 
         RESULTS OF OPERATIONS


         From time to time, the Company may make certain statements that contain
"forward-looking" information (as defined in the Private Securities Litigation
Reform Act of 1995), such as certain statements included in this Annual Report
on Form 10-K. Words such as "anticipate", "expect", "estimate", "project" and
similar expressions are intended to identify such forward-looking statements.
Forward-looking statements may be made by management orally or in written
material such as in press releases, portions of "Managements's Discussion and
Analysis of Financial Condition and Results of Operations" and "Business"
contained in this form 10-K, and portions of the Company's other filings with
the Securities and Exchange Commission under the Securities Act and the Exchange
Act.

         Although the Company believes that the expectations reflected in such
forward-looking statements are reasonable, it can give no assurance that such
expectations will prove to have been correct. Such forward-looking statements
are subject to certain risks, uncertainties and assumptions, including without
limitation those identified in Management's Discussion and Analysis of Financial
Condition and Results of Operations and "Business and Properties" contained
elsewhere in this Annual Report on Form 10-K. Should one or more of these risks
or uncertainties materialize, or should any of the underlying assumptions prove
incorrect, actual results of current and future operations may vary materially
from those anticipated, estimated or projected. Readers are cautioned not to
place undue reliance on these forward-looking statements, which speak only as of
their dates.

         Among the factors that may have a direct bearing on the Company's
results of operations and the oilfield services industry in which it operates
are changes in the price of oil and natural gas; the impact of competitive
products and pricing; the presence of competitors with greater financial
resources; product demand and acceptance risks, including product obsolescence
risks with respect to its downhole tools and directional drilling technology;
risks associated with the DWS/DAMCO Acquisition and the IDS Acquisition,
including failure to successfully manage the Company's growth and integrate the
operations acquired in such acquisitions; the Company's substantial leverage
following its recent offering of senior notes; typical operating risks inherent
in the oilfield services industry, including risks of environmental liability;
delays in receiving raw materials utilized in the manufacture and assembly of
the Company's downhole tools and other difficulties in the manufacture, assembly
or delivery of the company's downhole tools; worldwide political stability and
economic growth and other risks associated with international operations,
including foreign exchange risk; and the Company's successful execution of
internal operating plans as well as regulatory uncertainties and legal
proceedings.

CHANGE IN FISCAL YEAR

         In October 1997, the Company changed its' fiscal year end to December
31 from April 30. The Company believes such a change will allow the Company's
stockholders and other investors to more easily compare the Company's operating
results with those of other oil field services companies. As a result of the
change in fiscal year, rather than comparing calendar year results between 1997
and 1996, the following Management's Discussion and Analysis of Financial
Condition and Results of Operations compares operating results for the eight
month period ended December 31, 1997 (the "Transition Period") to the
corresponding period during 1996 (the "Corresponding Period"). The Company also
will begin reporting its quarterly results for the three month periods ended
March 31, June 30 and September 30, beginning with the three month period ending
March 31, 1998.

RECENT DEVELOPMENTS

         Industry Conditions. 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 



                                       13
<PAGE>   14

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.

        During the fiscal year ended April 30, 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 benefited the Company and its results in 1997 and 1996. In
recent months, however, the worldwide price of oil has recently declined to less
than $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 lower prices can be expected to
adversely affect the demand throughout the oil field services 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.

         Issuance of Senior Notes. On February 13, 1998, the Company issued $275
million principal amount of its 9 1/2% Senior Notes due 2008 (the "Senior
Notes"). Of the $267.1 million net proceeds to the Company, approximately $127.7
million were utilized to repurchase at a premium of 111% of their principal
amount all of the outstanding principal amount of the Company's 9 3/4% Senior
Notes due 2007 (the "Old Notes") and approximately $7.5 million were utilized to
repay outstanding debt under the Company's credit facility. The remaining net
proceeds will be utilized to fund capital expenditures, to fund future
acquisitions and for general and working capital purposes. The Senior Notes
significantly increased the Company's debt levels and will result in annualized
interest payments of approximately $26.1 million per year. As a result of the
repurchase of the Old Notes, the Company will record an extraordinary loss in
the first quarter of 1998 of approximately $17.8 million representing the excess
of the purchase price for the Old Notes over their carrying value on the date of
repurchase.

         IDS Acquisition. The Company acquired the outstanding capital stock of
IDS in March 1998 for approximately $9.4 million in cash and 1,064,600 shares of
Class A Common Stock, plus assumption of debt of approximately $10.6 million. As
a result of the IDS Acquisition, the Company acquired key technologies,
including a resistivity tool for LWD equipment that is compatible with Dailey's
MWD equipment. The Company believes that the addition of LWD technology to its
MWD equipment will allow the Company to offer more fully integrated directional
drilling services. As result of the IDS Acquisition, which will be accounted for
under the purchase method of accounting, the Company estimates that it will
record approximately $20.0 million in goodwill, representing the excess of the
purchase price over the estimated 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
deductible for tax purposes, the effective tax rate on Dailey's financial
statements will increase as a result of the acquisition.

         DWS/DAMCO Acquisition. The Company's operations and future results will
be significantly impacted by the DWS/DAMCO Acquisition, which was consummated in
January 1998. 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 in August 1997 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 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 

                                       14
<PAGE>   15

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 Company's acquisition (the "ADI Acquisition") of
Air Drilling International, Inc. ("ADI"), which was consummated in June 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 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 $18.9 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 $943,000 in annualized amortization expense. Since the goodwill
associated with the ADI Acquisition is not deductible 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 its 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
eight months ended December 31, 1997 associated primarily with staff reductions,
severance settlements and various reorganization costs. At December 31, 1997,
the Company had accrued $1.4 million related to severance settlements to be paid
through the third quarter of 1999. 

         1996 Initial Public Offering. Dailey's operations during the fiscal
year ended April 30, 1997 reflect the effects of its initial public offering in
the fiscal year ended April 30, 1996. 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.

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
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 



                                       15
<PAGE>   16

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.

TRANSITION PERIOD ENDED DECEMBER 31, 1997 COMPARED TO THE CORRESPONDING PERIOD
ENDED DECEMBER 31, 1996

    Rental Income. Rental income for the Transition Period ended December 31,
1997, was $42.5 million, an increase of 26% from $33.8 million for the
Corresponding Period ended December 31, 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
$4.5 million increase in rentals from MWD equipment, downhole motors and other
directional drilling tools. In addition, rental income from drilling and fishing
jars and slingers increased $1.6 million domestically primarily due to increased
demand as the average rig count in the United States increase 21% and $2.5
million internationally, primarily in the Far East, Australia, Middle East and
Europe.

    Sales of Products and Services. Sales of products and services for the
Transition Period ended December 31, 1997, were $15.0 million, an increase of
31% from $11.5 million for the Corresponding Period ended December 31, 1996.
This increase was primarily the result of ADI pipeline testing revenue of $1.5
million being included in operating results for the first time, an increase in
revenue from tools lost-in-hole of $1.1 million and 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 $1.2 million increase
in directional services revenue. This was partially offset by decreased sales of
tools and parts of $388,000.

    Underbalanced Drilling Services Revenue. Underbalanced drilling services
revenue for the Transition Period ended December 31, 1997 was $18.7 million
resulting from ADI revenue being included in operating results since June 20,
1997.

    Cost of Rentals. Cost of rentals for the Transition Period ended December
31, 1997, was $29.6 million, an increase of 17% from $25.4 million for the
Corresponding Period ended December 31, 1996. 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. Gross margins
increased from 25% for the eight months ended December 31, 1996 to 30% for the
eight months ended December 31, 1997 due to the primarily fixed nature of
Dailey's cost base.

     Cost of Products and Services. Cost of products and services for the
Transition Period ended December 31, 1997, was $9.2 million, including a
$904,000 increase due to ADI being included in operating results since June 20,
1997, an increase of 49% from $6.2 million for the Corresponding Period ended
December 31, 1996. Excluding the impact of ADI, the gross profit margin on sales
of products and services for the Transition Period ended 



                                       16
<PAGE>   17

December 31, 1997 was 38% compared to 46% for the Corresponding Period 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 Transition Period ended December 31, 1997 was $12.0 million
resulting from ADI being included in operating results since June 20, 1997.

         Selling, General and Administrative Expenses. For the Transition Period
ended December 31, 1997, selling, general and administrative expenses were $14.7
million, an increase of 84% from $8.0 million for the Corresponding Period ended
December 31, 1996. 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
since June 20, 1997. Cost savings from the Reorganization partially offset this
increase.

         Reorganization Costs. Reorganization costs for the Transition Period
ended December 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 Transition
Period ended December 31, 1997 was $661,000, 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").

         Research and Development Expenses. Research and development expenses
for the Transition Period ended December 31, 1997, were $190,000, compared to
$549,000 for the Corresponding Period ended December 31, 1996. This decrease is
the result of having substantially completed research and development
projects related to mud motors, fishing jars, and adapting fishing jars to
coiled tubing operation.

         Interest Income. Interest income for the Transition Period ended
December 31, 1997, was $1.3 million, compared to $410,000 from the Corresponding
Period ended December 31, 1996. This was the result of interest earned on
short-term investments utilizing net proceeds from the issuance of the Old Notes
in August 1997.

         Interest Expense - Nonaffiliates. Interest expense to nonaffiliates
for the Transition Period ended December 31, 1997 was $5.3 million compared to
$486,000 for the Corresponding Period ended December 31, 1996. This increase was
primarily the result of interest incurred on the Old Notes issued in August
1997.

         Income Tax Expense. Income tax expense for the Transition Period ended
December 31, 1997, was $1.3 million, a decrease of 28% from $1.8 million for the
Corresponding Period ended December 31, 1996. This decrease was primarily the
result of lower income before income taxes. This decrease was partially offset
by an increase in the effective tax rate to 44% for the Transition Period from
36% for the Corresponding Period due to the full utilization of state net
operating loss carryforwards during the year ended April 30, 1996 and the
non-deductibility of goodwill recorded in connection with the ADI Acquisition.

<PAGE>   18

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.

     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
the fiscal year ended April 30, 1996 to 76% in the fiscal year ended April 30,
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 the fiscal year ended April 30,
1997 was 48% compared to 50% for the fiscal year ended April 30, 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 the fiscal year ended April 30, 1996.

     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.

     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 the fiscal year ended April 30, 1997 from 35% for the fiscal
year ended April 30, 1996 due to the full utilization of state net operating
loss carryforwards for the fiscal year ended April 30,  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 Venezuela, the Gulf of
Mexico and the U.S. Gulf Coast region, which resulted in a $4.2 million increase
in rentals from MWD equipment, downhole motors and other directional drilling
tools. During the fiscal year ended April 30, 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 increased demand in Latin America and to
a slight increase in pricing worldwide. Also in the fiscal year ended April 30,
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 the fiscal year ended April 30,
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 fiscal year ended April 30, 1996.

    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 fiscal year ended April 30, 1996 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.

                                      19

    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.

    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 the fiscal year ended April
30, 1995 to the fiscal year ended April 30, 1996. In the fiscal year ended April
30, 1996, Dailey recorded 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.

LIQUIDITY AND CAPITAL RESOURCES

         Working Capital. Working capital at December 31, 1997 was $70.4 million
compared to $21.9 million as of April 30, 1997. Cash provided by operating
activities was $10.7 million during the Transition Period ended December 31,
1997. Additional sources of cash included net proceeds from the issuance of debt
of $159.6 million, $2.0 million from revenue-producing tools lost-in-hole,
abandoned and sold, $703,000 from stock options exercised and $617,000 of
proceeds from the sale of property and equipment. Principal uses of cash for the
Transition Period ended December 31, 1997 were to fund the ADI Acquisition (net
of cash acquired) of $46.2 million, repay bank debt of $52.8 million, purchase
treasury stock of $813,000, pay financing costs relating to the issuance of the
Old Notes of $4.1 million and fund capital expenditures of $24.8 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 its credit facility with Wells Fargo Bank (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 Senior Notes. The Company is prohibited from borrowing funds
under the Credit Facility until such renegotiation is complete.

                                      20
<PAGE>   21
         Senior Notes. The Senior Notes were issued pursuant to an indenture
dated February 13, 1998 (the "Indenture"). The Indenture contains various
covenants customary in such instruments, including covenants that (i) restrict
the Company's ability to incur additional indebtedness; (ii) restrict the
Company's ability to make restricted payments, including dividends; (iii)
restrict the Company's ability to sell assets; (iv) restrict the Company's
ability to grant liens on its assets; (v) limit transactions with affiliates and
(vi) limit the Company's ability to engage in certain extraordinary
transactions, including transactions involving a change in control of the
Company or the sale of substantially all of the Company's assets. The Senior
Notes are guaranteed by all of the Company's domestic subsidiaries, bear
interest at 9 1/2% that is payable semi-annually on February 15 and August 15 of
each year, mature on February 15, 2008 and are redeemable at the option of the
Company for stipulated redemption prices on or after February 15, 2003. The
issuance of the Senior Notes substantially increased the Company's level of
indebtedness over historical levels. As of March 19, 1998, the Company had
outstanding approximately $275.1 million in long-term debt excluding capital
leases compared to $6.9 million at April 30, 1997. The Company's increased level
of indebtedness will have several important effects on the Company's future
operations, including (i) a substantial portion of the Company's cash flows 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 and general corporate and other purposes may be limited.

         Capital Expenditures. Capital expenditures of approximately $24.8
million were made during the Transition Period ended December 31, 1997. Of this
amount, $16.4 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 are expected to be approximately $38 million. The
Company believes it will have available resources from the remaining net
proceeds from the issuance of the Senior Notes, internally generated cash flows
and availability under the Credit Facility to fund operations for at least the
next twelve months. 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, 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 connection with any future acquisitions, the Company may be
required to incur substantial indebtedness to finance such acquisitions and may
also issue equity securities or convertible securities.

         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 the 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 Company repurchased all of
the Old Notes on February 15, 1998 utilizing a portion of the net proceeds from
the issuance of the Senior Notes. As a result of the repurchase of the Old
Notes, the Company will record an extraordinary loss in the first quarter of
1998 of approximately $17.8 million, or $1.91 per diluted share, representing
the excess of the purchase price for the Old Notes over their carrying value on
the date of repurchase.

INFLATION AND FOREIGN EXCHANGE

     Inflation has not had a significant impact on Dailey's comparative results
of operations. For the Transition Period ended December 31, 1997, transactions
conducted in United States dollars accounted for approximately 78% of the
Company's total revenues. The Company believes that the percentage of its total
revenues relating to transactions conducted in foreign currencies will continue
to 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.

NEW ACCOUNTING PRONOUNCEMENTS

         SFAS No. 130. In June 1997, the Financial Accounting Standards Board
(the "FASB") issued Statement of Financial Accounting Standards No. 130,
Reporting Comprehensive Income, which establishes standards for reporting and
display of comprehensive income and its components. SFAS No. 130 requires that
all items that are recognized under accounting standards as components of
comprehensive income be reported in a financial statement displayed in equal
prominence with the other financial statements. SFAS No. 130 is effective for
both interim and annual periods beginning after December 15, 1997, at which time
the Company will adopt the provisions. The Company does not expect SFAS No. 130
to have a material effect on the Company's financial statements.

         SFAS No. 131. Also in June 1997, the FASB issued SFAS No. 131,
Disclosures about Segments of an Enterprise and Related Information, which is
effective for fiscal 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 issued to shareholders. It also establishes standards
for related disclosures about products and services, geographic areas and major
customers. The Company will adopt the new requirements in the fourth quarter of
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 financial statements.

    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 June 30, 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.

                         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 December 31, 1997 and April 30, 1997 and 1996, and the
related consolidated statements of operations, stockholders' equity, and cash
flows for the eight month period ended December 31, 1997 and for each of the
three years in the period ended April 30, 1997. Our audits also included the
consolidated financial statement schedule listed in the Index at Item 14(a).
These financial statements and schedule are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements and schedule 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 December 31, 1997 and April 30, 1997 and 1996, and
the consolidated results of its operations and its cash flows for the eight
month period ended December 31, 1997 and for each of the three years in the
period ended April 30, 1997, in conformity with generally accepted accounting
principles. Also, in our opinion, the related financial statement schedule, when
considered in relation to the basic financial statements taken as a whole,
presents fairly in all material respects the information set forth therein.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                DECEMBER 31, 1997

1. 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 changed its name to Dailey Petroleum Services
Corp.). In October 1997, Dailey Petroleum Services Corp. changed its name to
Dailey International Inc., hereinafter referred to as the "Company" or
"Dailey."


    In October 1997, the Company changed its fiscal year end to December 31,
effective December 31, 1997. For purposes of this financial statement
presentation, the eight month period ended December 31, 1997 represents the
transition period from May 1, 1997 (April 30, 1997 being the last fiscal
year end) through December 31, 1997. The unaudited results for the eight
months ended December 31, 1996 have been presented for comparative purposes.

     The Company is an integrated supplier of specialty services and a provider
of technologically-advanced downhole tools to the oil and gas industry on a
worldwide basis. 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. In June 1997, the
Company acquired Air Drilling International, Inc. ("ADI" and the "ADI
Acquisition") 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 called 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, Class B Common Stock and Preferred Stock. 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).

     Net proceeds from the sale of the stock in the 1996 IPO 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 IPO, the Company's sole stockholder contributed to the
capital of the Company $5.0 million of the outstanding principal of such note.
The statement of operations for the year ended April 30, 1996 includes 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.

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 consolidated financial
statements on the basis established between the Company and Lawrence. See Notes
7, 8, and 11.

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 maturities 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 $1.8
million at December 31, 1997 and $1.5 million and $1.3 million at April 30, 1997
and 1996, respectively.

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.

Capitalized Interest

     Interest costs for the construction of revenue-producing tools are
capitalized. The Company capitalized interest costs of $396,000 on work in
progress for the eight months ended December 31, 1997. Such amounts were
not significant in prior periods.

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.



                                       44

<PAGE>   45
Intangible Assets

     Patents and other intangibles are amortized over 5 to 17 years and goodwill
is amortized over 20 to 40 years. Accumulated amortization, including goodwill
amortization, was $1.2 million, $386,000 and $323,000 as of December 31, 1997
and April 30, 1997 and 1996, respectively.

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 No. 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 14).

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 basis 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.

                                      

                                       45




<PAGE>   46
    The Company was included in the consolidated U.S. federal income tax return
of Lawrence for taxable periods ending on the closing of the 1996 IPO. The
Company and Lawrence are jointly and severally liable with respect to taxes
related to periods prior to the 1996 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 Exchange

     The U.S. dollar is the functional currency for the majority of the
Company's operations. Accordingly, foreign currency exchange gains and losses
are recognized in the consolidated statements of operations. Foreign exchange
gain (loss) for the eight months ended December 31, 1997 and 1996 was $296,000
and ($135,000), respectively, and for the fiscal years ended April 30, 1997,
1996 and 1995 was $19,000, $239,000 and ($90,000), respectively.

Earnings Per Share

     The Company has reported earnings per share for all periods in accordance
with the Financial Accounting Standards Board ("FASB") Statement No. 128,
Earnings per Share (SFAS No. 128), and has restated all prior periods. Under the
new requirements for calculating basic earnings per share, the dilutive effect
of stock options has been excluded. The method of calculating diluted earnings
per share is similar to fully diluted earnings per share which was previously
not required to be reported if the effect of the dilution was less than three
percent. SFAS No. 128 resulted in no change in restated basic earnings per share
for the years ended April 30, 1997, 1996 and 1995.

  New Accounting Pronouncements

     SFAS No. 130. In June 1997, the FASB issued SFAS No. 130, Reporting
Comprehensive Income, which establishes standards for reporting and display of
comprehensive income and its components. SFAS No. 130 requires that all items
that are recognized under accounting standards as components of comprehensive
income be reported in a financial statement displayed in equal prominence with
the other financial statements. SFAS No. 130 is effective for both interim and
annual periods beginning after December 15, 1997, at which time the Company will
adopt the provisions. The Company does not expect SFAS No. 130 to have a
material effect on the Company's financial statements.

    SFAS No. 131. Also, in June 1997, the FASB issued SFAS No. 131, Disclosures
about Segments of an Enterprise and Related Information, which is effective for
fiscal 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 issued to shareholders. It also establishes standards for
related disclosures about products and services, geographic areas and major
customers. The Company will adopt the new requirements in the fourth quarter of
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 financial statements.

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 $18.9 million relating to the excess of the purchase
price over the fair market value of ADI's assets, which will be amortized over
20 years and result in approximately $943,000 in amortization expense per year.
The accompanying consolidated Statement of Operations includes the results of 
ADI since June 20, 1997. The purchase price allocation was based on preliminary
estimates and may be revised at a later date.

    The pro forma unaudited results of operations, 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 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 effected on the

7. RELATED PARTY TRANSACTIONS

    The accompanying consolidated statements of operations include annual rental
charges from Lawrence and from an executive for a corporate office facility and
manufacturing and service center facilities. See Note 11.

    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 all periods
presented. During the years ended April 30, 1996 and 1995, the Company also
utilized from time to time aircraft owned by a Lawrence subsidiary. The effect
of the estimated fair values of these services rendered less services received
was not significant to the results of operations.

    The Company participates in the "Lawrence Companies Retirement Plan", a
defined contribution benefit plan, covering all Dailey employees. Contributions
are determined as 50% of the employee's contribution up to 3% of the employee's
total compensation. Amounts charged to benefit costs and contributed to the plan
for the years ended April 30, 1997, 1996 and 1995 totaled $203,000, $178,000 and
$152,000, respectively. Amounts charged to benefit costs and contributed to the
plan for the eight months ended December 31, 1997 and 1996 were $212,000 and
$142,000, respectively.

8. BORROWING ARRANGEMENTS

    Interest paid during the years ended April 30, 1997, 1996 and 1995 was
$858,000, $956,000 and $1,128,000, respectively. Interest paid for the eight
months ended December 31, 1997 and 1996 was $683,000 and $658,000, respectively.

    The Company entered into a 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%. The obligations 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,
allowable borrowings under the revolving credit facility were increased to the
lesser of $15.0 million or a loan formula based upon the receivable level of
eligible accounts receivable. The revolving credit facility matures on June 30,
2002. Interest on 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. At December 31, 1997, the
Company had no outstanding borrowings under this credit facility and available
borrowing capacity was $11.3 million.

    On August 19, 1997, the Company issued $115.0 million of 9 3/4% Senior Notes
due 2007 at a discount of 0.785%, and a portion of the proceeds was used to
repay the outstanding note payable to a bank. See Note 16.

</TABLE>

    At December 31, 1997, the Company had foreign net operating loss
carryforwards of approximately $3.0 million which can be carried forward
indefinitely. The Company also had approximately $1.6 million of domestic net
operating loss carryforwards which will begin to expire in 2011. The domestic
net operating loss carryforwards are subject to certain separate return and
change in ownership limitations. Accordingly, the Company has recorded a
valuation allowance of $553,000 against these net operating loss carryforwards
as the Company believes that the corresponding deferred tax assets may not be
realizable.
    At December 31, 1997 and April 30, 1997, the valuation allowance was
$553,000 and $1.1 million, respectively. In connection with the Company's
decision to change its fiscal year end to December 31, the Company determined
that the net foreign tax credit carryforward could not be utilized and was
therefore written off resulting in a $1.1 million decrease in the valuation
allowance. In addition, the Company recorded a $553,000 valuation allowance
against its domestic net operating loss carryforwards.
    No provision is made for U.S. income and foreign withholding taxes
applicable to undistributed earnings of foreign subsidiaries as those earnings
are considered to be permanently reinvested.

    The Company is currently engaged in tax audits and appeals in various tax
jurisdictions. The years covered by each audit or appeal vary considerably among
legal entities. Assessments, if any, are not expected to have a material adverse
effect on the financial statements.

    Income taxes paid during fiscal year ended April 30, 1997, 1996 and 1995
were $608,000, $538,000 and $917,000, respectively. Income taxes paid for the
eight months ended December 31, 1997 and 1996 were $2.0 million and $461,000,
respectively.


10. 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. Royalty agreements were executed between the Company
and the royalty owner in 1993 and 1994 on 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 through December 1999, with
the royalty percentage decreasing from January 2000 to expiration of the
applicable patents. Upon expiration of the patents, no royalties will be
required. For the years ended April 30, 1997, 1996 and 1995, royalty expense was
$879,000, $843,000 and $826,000, respectively. For the eight months ended
December 31, 1997 and 1996 royalty expense was $742,000 and $608,000,
respectively. The owner of the royalty was an officer of the Company until
October 1994.

    Rental expense under operating leases with third parties, inclusive of
month-to-month rentals, totaled $2.2 million, $2.4 million and $1.7 million for
the years ended April 30, 1997, 1996 and 1995, respectively, and, with related
parties, totaled $915,000, $1.3 million and $1.2 million for the years ended
April 30, 1997, 1996 and 1995, respectively. For the eight months ended December
31, 1997 and 1996, rental expense under operating leases with third parties,
inclusive of month-to-month rentals, totaled $2.7 million and $2.0 million
respectively, and, with related parties, totaled $671,000 and $593,000,
respectively. Rental expense is 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.

12. 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.

    Carrying amount and fair values: The carrying amount and estimated fair
values of financial instruments are as follows:

</TABLE>

    Fair value methods: The following methods and assumptions were used in
estimating fair values:

         For cash and short-term financial assets, the carrying amount is a
reasonable estimate of fair value due to the short maturity of those
instruments.

         For Senior Notes, estimated fair value is based on quoted market prices
at year end. The fair values of the Company's long-term bank notes and other
debt are estimated using discounted cash flow analyses, based on the Company's
current incremental borrowing rates for similar types of borrowing arrangements.

</TABLE>

    Options to purchase 62,000 shares of common stock at prices from $9.75 to
$13.25 per share were outstanding during the eight months ended December 31,1997
but were not included in the computation of diluted earnings per share because
the exercise price was greater than the average market price of the common
shares, and therefore, the effect would be antidilutive.

    Restricted stock grants of 230,000 shares of common stock were unvested at
December 31, 1997, but were not included in the computation of diluted earnings
per share because their inclusion would be antidilutive.

14.   STOCK OPTIONS AND AWARDS

    Prior to the 1996 IPO, the Company established the 1996 Key Employee Stock
Plan (the "1996 Plan") and the 1996 Non-Employee Director Stock Option Plan (the
"1996 Director Plan"). Pursuant to the 1996 Plan, the Board of Directors of the
Company is authorized to issue up to 900,000 shares of the Company's Class A
Common Stock. On October 7, 1997, the Board of Directors approved the 1997
Long-Term Incentive Plan (the "1997 Plan"). Pursuant to the 1997 Plan, the Board
of Directors of the Company is authorized to issue up to 720,000 shares of the
Company's Class A Common Stock.

     The Company applied Accounting Principals Board Opinion No. 25 ("APB No.
25") and related interpretations in accounting for these plans. Accordingly, no
compensation cost has been recognized during the Transition Period ended
December 31,1997 and the year ended April 30, 1997 for these plans. 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 .60 and
risk free interest rates ranging from 5.66% to 5.71%. The Company does not
presently anticipate issuing dividends in the future. Had compensation cost for
the Company's 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 No. 123, the Company's net income and earnings per share
for the eight months ended December 31,1997 and the year ended April 30, 1997
would have been reduced to the pro forma amounts listed below. There were no
options issued in the years ended April 30, 1996 or 1995.

     Stock options under the Plans are for Class A Common Stock and have
exercise prices equal to fair market values at dates of grant. Options issued
under the 1996 Plan may not be exercised within six months of, nor after ten
years from, the date of grant. Options issued under the 1996 Director Plan may
not be exercised within one year of, nor after ten years from, the date of
grant. Options issued under the 1997 plan may not be exercised after ten years
from the date of grant. The average remaining contractual life of options
outstanding is approximately nine years. Option activity for the eight months
ended December 31, 1997 and year ended April 30, 1997 was as follows:

     Immediately following the 1996 IPO, restricted stock awards totaling
360,000 shares of Class A Common Stock were granted to key officers. In October
1996, a restricted stock award of 45,000 shares of 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 restricted stock awards which resulted
in the Company recognizing $2.8 million and $478,000 in non-cash compensation
expense for the year ended April 30, 1997 and the eight months ended December
31, 1997, respectively. In October 1997, restricted stock awards totaling
230,000 shares of Class A Common Stock were granted to certain officers. The
awards do not require any payment by the officers and vest over a four year
period. During the eight months ended December 31, 1997, the Company recognized
$183,000 of non-cash compensation expense related to these awards. Restricted
stock activity for the year ended April 30, 1997 and the eight months ended
December 31, 1997 was as follows:

15. REORGANIZATION

    In June 1997, 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, the Company incurred a $2.5 million
restructuring charge during June 1997 associated primarily with staff
reductions, severance settlements and various reorganization costs. The
Management Reorganization was completed during the eight months ended
December 31, 1997.

16. SUBSEQUENT EVENTS

    DWS/DAMCO Acquisition. In January 1998, the Company acquired the
operating assets and liabilities of Directional Wireline Services, Inc. ("DWS"),
DAMCO Tong Services, Inc. and DAMCO Services, Inc. (collectively, "DAMCO", and
with DWS, "DWS/DAMCO" or the "Companies"), which are headquartered in Houma,
Louisiana. The Companies provide specialized drilling, workover, completion and
production services to the Gulf of Mexico and Nigerian markets. The aggregate
purchase price for the Companies was $61 million financed with proceeds from the
$115 million of 9 3/4% senior notes offering in August 1997 and borrowings under
its revolving credit facility. The acquisition will be accounted for under the
purchase method of accounting.

    Issuance of Senior Notes. On February 13, 1998, the Company issued $275
million 9 1/2% Senior Notes due 2008. Of the $267.1 million net proceeds to the
Company, approximately $127.7 million were utilized to repurchase at a premium
of 111% of their principal amount all of the outstanding principal amount of the
Company's 9 3/4% Senior Notes (the "Old Notes") and approximately $7.5 million
were utilized to repay outstanding debt under the Company's revolving credit
facility. As a result of the repurchase of the Old Notes, the Company will
record an extraordinary loss in the first quarter of 1998 of approximately $17.8
million, or $1.91 per diluted share, with no related income tax benefit
representing the excess of the purchase price for the Old Notes over their
carrying value on the date of repurchase. The Senior Notes are unsecured senior
obligations of the Company. The Senior Notes are unsecured senior obligations of
the Company and are redeemable at the option of the Company on or after February
15, 2003 at stipulated redemption prices.

    IDS Acquisition. The Company acquired the outstanding capital stock of
Integrated Drilling Systems, Limited ("IDS") on March 24, 1998 for approximately
$9.4 million in cash and 1,064,600 shares of Class A Common Stock, plus
assumption of debt of approximately $10.6 million (the "IDS Acquisition"). The
IDS Acquisition will be accounted for under the purchase method of accounting.
The Company estimates that it will record approximately $20.0 million in
goodwill, representing the excess of the purchase price over the estimated 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 deductible for tax purposes,
the effective tax rate on Dailey's financial statements will increase as a
result of the acquisition.

    Four Corners Air Service Acquisition. 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.
