PART I

ITEM 1. BUSINESS

GENERAL

Grey Wolf, Inc. is a leading provider of contract land drilling
services in the United States with a domestic fleet of 120 rigs at March 23,
1998. In addition to its domestic operations, the Company operates a fleet of
six rigs in Venezuela, giving the Company a total of 126 rigs, 111 of which are
actively marketed. The Company believes that it has the largest fleet of land
drilling rigs in its Gulf Coast and South Texas markets and the second largest
fleet in its Ark-La-Tex and Mississippi/Alabama markets. The Company has an
inventory of 15 non-marketed rigs that it intends to refurbish and reactivate
during 1998 and 1999 as demand warrants.

The Company is a Texas corporation formed in 1980. Over the two year
period ending December 31, 1997, the Company implemented a new strategy whereby
it elected a substantially new board of directors, installed new senior
management and completed several acquisitions, mergers and financing
transactions that significantly improved its liquidity, added drilling rigs to
its existing fleet, and substantially increased the number of its personnel. The
combined effect of the Company's change in operating strategy, larger fleet of
marketable rigs, higher rig utilization rates and increasing day rates
significantly improved the Company's financial performance during 1997. For the
year ended December 31, 1997, the Company reported net income of $10.2 million,
which was the Company's first profitable year since 1991.

As used herein, the term "Company" refers to Grey Wolf, Inc. and its
subsidiaries, unless the context otherwise indicates. Prior to September 19,
1997, the Company's corporate name was DI Industries, Inc. The Company's
principal office is located at 10370 Richmond Avenue, Suite 600, Houston, TX
77042, and its telephone number is (713) 435-6100.

BUSINESS STRATEGY

In April 1996, the Company initiated a reorganization of its operations
that consisted of replacing substantially all of the senior management and the
members of the Board of Directors of the Company and implementing a new business
strategy. This business strategy seeks to achieve increased cash flow and
earnings through:

(1) focusing on core markets and establishing leading positions in
these markets;
(2) refurbishing and reactivating inventoried rigs to satisfy
increases in demand;
(3) acquiring land drilling businesses and assets to capitalize on
anticipated improvements in the industry; and
(4) attracting, retaining and training qualified personnel to
support the Company's increased level of operations.

Focus on Core Markets. The Company focuses on its four core domestic
drilling markets as it believes these markets have historically maintained
higher utilization rates and day rates than other domestic markets. The Company
believes it currently has the leading market position in its Gulf Coast and
South Texas markets and the second leading market position in its Ark-La-Tex and
Mississippi/Alabama markets. By focusing on its core markets and establishing
leading positions in these markets, the Company is able to achieve economies of
scale and provide an infrastructure to acquire, refurbish and reactivate rigs in
these markets in a cost-effective manner. Internationally, the Company
concentrates its efforts in Venezuela, where the Company intends to increase its
market presence and is currently bidding on a number of potential drilling
projects.

Refurbishment and Reactivation of Inventoried Rigs. From the beginning
of the fourth quarter of 1996 through the first quarter of 1998, the Company has
refurbished and reactivated 26 rigs. The remaining 15 rigs in the Company's
inventory at March 23, 1998 are planned for refurbishment and reactivation
during 1998 and 1999 based on market demand.

Acquisitions. The Company has aggressively implemented its new
operating strategy by acquiring 100 land drilling rigs in 13 transactions from
August 1996 through Mid-March, 1998. Six of these acquisitions were of


-2-

3

companies with long operating histories in the Company's Ark-La-Tex,
Mississippi/Alabama, Gulf Coast and South Texas markets. The other acquisitions
have provided the Company with additional inventory of drilling rigs suited for
refurbishment and reactivation in the Company's core domestic markets, Venezuela
or other foreign markets.

Attracting, Retaining and Training Qualified Personnel. The Company
believes that its executive management and operating personnel are among the
most experienced and highly skilled professionals in the contract drilling
industry. Thomas P. Richards, the Company's President and CEO, has 32 years of
contract drilling industry experience and the Company's four Senior Vice
Presidents have an average of 24 years of related experience. Many of the
Company's operating personnel joined the Company in connection with acquisitions
completed since August 1996, bringing to the Company additional customer
relationships and operating experience in their markets. The Company's ability
to retain these employees and to attract additional quality employees has
allowed the Company to expand its operations and customer base significantly
while ensuring quality service to its customers. The Company has a training
program in place to ensure that an adequate number of qualified supervisory
personnel are available for future expansion.

INDUSTRY OVERVIEW

The domestic land drilling industry is undergoing a period of rapid
consolidation. The Company believes that during the period from January 1, 1996
through January 31, 1998, there have been at least 39 completed or pending
transactions involving the acquisition of a combined total of approximately 509
rigs, the majority of which were acquired by six land rig companies including
the Company. The Company accounted for 13 of these transactions which involved
its acquisition of 100 rigs, of which 67 were actively marketed at the time of
acquisition and 33 were inventoried for later refurbishment.

Industry sources estimate that the supply of domestic land drilling
rigs available for work in the U.S. has declined from over 5,000 rigs in 1982 to
1,400 rigs currently. The Company believes the demand for land drilling rigs in
the Company's core markets increased during 1997 principally due to improved oil
and gas drilling and production economics resulting from increased use of 3-D
seismic, directional drilling and enhanced recovery techniques. For 1997,
industry sources estimate that the average active domestic land rig count was
822 as compared to 652 for 1996.

RECENT ACQUISITIONS AND SALES

Murco Acquisition. On January 30, 1998, the Company closed the
acquisition of all of the outstanding common stock of Murco Drilling Corporation
("Murco") for $59.6 million in cash. At closing, Murco had net liabilities of
approximately $5.4 million. The Company funded this acquisition through the use
of working capital and its bank credit facility. Murco operated ten land
drilling rigs in the Ark-La-Tex and Mississippi/Alabama regions. The rigs
acquired consisted of two 1,500 horsepower Silicon Controlled Rectifier ("SCR")
rigs, one 1,000 horsepower SCR rig, one 800 horsepower SCR rig and six
mechanical rigs with horsepower ratings from 650 to 1,500.

Justiss Acquisition. On September 15, 1997, the Company entered into a
definitive agreement to acquire substantially all of the operating assets of
Justiss Drilling Company, a division of Justiss Oil Company, Inc. ("Justiss").
The assets included a fleet of 12 operating drilling rigs and related equipment
which are currently operating in the Company's Ark-La-Tex and Gulf Coast
markets. The total purchase price for the Justiss Acquisition is $ 36.1 million
in cash of which $28.6 million was paid on October 31, 1997 upon delivery of
nine of the 12 rigs to be acquired. The remaining three rigs were purchased and
the balance of the purchase price paid ($7.5 million) during November 1997 as
each rig completed a turnkey drilling contract for a well in progress.
Approximately 240 former rig-based employees of Justiss were hired by the
Company.

Kaiser-Francis Rig Purchase. On August 21, 1997, the Company acquired
six idle drilling rigs and related drilling equipment from Cactus Drilling
Company, a division of Kaiser-Francis Oil Company for a cash purchase price of
$25.4 million. The rigs consisted of four 2,000 horsepower Silicon Controlled
Rectifier ("SCR") rigs, one 1,000 horsepower SCR rig and one 1,000 horsepower
mechanical rig. The 2,000 horsepower rigs are rated for drilling to 25,000 feet
while the 1,000 horsepower rigs are rated for drilling to 15,000 feet. Three of
the six rigs are currently being refurbished and three were refurbished and
placed in service in late 1997 and early 1998. The purchase price for the
Kaiser-Francis Rig Purchase was paid from the net proceeds of the Senior Notes
offering.

GWDC Acquisition. On June 27, 1997, the Company acquired Grey Wolf
Drilling Company ("GWDC") which owned a fleet of 18 operating drilling rigs and
related assets located in the Company's Gulf Coast market. Sixteen of the rigs
acquired in the GWDC Acquisition are rated to drill to depths of 20,000 feet or
greater. The consideration for the GWDC Acquisition consisted of $61.6 million
in cash and 14.0 million shares of common stock valued by the Company at $47.6
million under the purchase method of accounting. The GWDC Acquisition
established the Company's presence in its Gulf Coast market and provided the
Company with additional infrastructure to facilitate reactivation of its rigs
held in inventory.

Flournoy Acquisition. On January 31, 1997, the Company acquired the
operating assets of Flournoy Drilling Company ("Flournoy") for approximately
12.4 million shares of common stock and cash of approximately $800,000, which
was utilized to repay certain indebtedness of Flournoy. The assets acquired
included 13 operating land drilling rigs, 17 rig hauling trucks, a yard and
office facility in Alice, Texas and various other equipment and drill pipe.
Under the purchase method of accounting, the Company valued the common stock in
the Flournoy Acquisition at $31.1 million. The Company agreed to issue
additional shares of common stock to Flournoy's shareholders if, and to the
extent that, on January 31, 1998 the aggregate market value of one-half of the
shares received by the Flournoy shareholders less any shares sold, plus the
gross proceeds from certain sales of common stock received in the transaction by
the Flournoy shareholders prior to January 31, 1998, is in total, less than
$12.4 million. No additional shares were required to be issued.

Diamond M Acquisition. On December 31, 1996, the Company acquired the
assets of Diamond M Onshore, Inc. ("Diamond M") for $26.0 million in cash. The
assets acquired consisted of ten operating land drilling rigs, all of which are
currently operating in South Texas, 19 rig hauling trucks, a yard and office
facility in Alice, Texas and various other drill pipe and equipment.

Mesa Acquisition. On October 3, 1996, the Company acquired six diesel
electric SCR rigs, three of which were operating, from Mesa Drilling, Inc.
("Mesa") in exchange for 5.5 million shares of common stock. The Mesa
acquisition established the Company's presence in South Texas. Under the
purchase method of accounting, the Company valued the common stock issued in the
Mesa Acquisition at $7.5 million.

RTO/LRAC and Somerset Acquisitions. On August 29, 1996, the Company
completed the RTO/LRAC Acquisition in which approximately 39.4 million shares of
common stock were exchanged for 18 deep drilling land rigs which were added to
the Company's rigs held for refurbishment and reactivation. The rigs acquired in
the RTO/LRAC Acquisition include five 3,000 horsepower and nine 2,000 horsepower
land rigs rated for depths of 25,000 feet or greater. Contemporaneously with the
closing of the RTO/LRAC Acquisition, the Company completed a transaction in
which it issued approximately 39.4 million shares of common stock for $25.0
million in cash. Under the purchase method of accounting, the Company valued the
common stock issued in the RTO/LRAC Acquisition and the Somerset Acquisition at
$25.0 million and $24.6 million, respectively. The recipients of the shares
issued in the RTO/LRAC and Somerset Acquisitions were also issued warrants to
acquire up to an aggregate of 3.4 million shares of common stock (the "Shadow
Warrants"), exercisable upon the occurrence of certain events. As of December
31, 1997, approximately 2.9 million of the Shadow Warrants have been terminated
unexercised. The $25.0 million capital infusion from the Somerset Acquisition
was used for rig fleet refurbishment, debt repayment and general corporate
purposes.

Additional Rig Purchases. In addition to the acquisitions described
above, the Company completed five additional acquisitions during the second and
third quarters of 1997 that added a total of seven drilling rigs to the
Company's fleet, one of which was operating and six of which were added to the
Company's rigs held for refurbishment.

Sale of INDRILLERS, L.L.C. On November 13, 1997, the Company closed the
sale of its 65% interest in INDRILLERS, LLC ("Indrillers") and certain related
drilling assets to Dart Energy Corporation ("Dart") in exchange for $1.65
million in cash and title to a 1,200 horsepower SCR rig previously held by
Indrillers. Indrillers, a limited liability company, operated drilling rigs in
Michigan and was formed in 1996 through the combination of certain drilling
assets of the Company and Dart with resulting ownership of 65% and 35%,
respectively. Indrillers' rig fleet consisted of nine smaller mechanical rigs
ranging from 300 to 900 horsepower and one 1,200 horsepower SCR rig.

Sale of Eastern Division Assets. On February 26, 1998, the Company
signed a definitive agreement to sell all of the rigs and drilling related
equipment of the Company's Eastern Division located in Ohio to Union Drilling,
Inc. ("Union") for $2.4 million. The sale closed in steps as each of the rigs
completed its current drilling contract with the


-4-

last transaction being completed on March 4, 1998. The Eastern division's rig
fleet consisted of six 450 horsepower mechanical rigs.

DOMESTIC OPERATIONS

At December 31, 1997, the Company had a total domestic rig fleet of 116
rigs, 100 of which were being actively marketed, and 16 of which were held in
inventory for refurbishment and reactivation. After giving effect to the Murco
Acquisition and the disposition of the Eastern Division assets, the Company's
domestic total rig fleet at March 23, 1998 consists of 126 rigs, 111 of which
are actively marketed and 15 of which are held for refurbishment and
reactivation.

The Company conducts its domestic operations primarily in its four core
domestic drilling markets, the Ark-La-Tex, Mississippi/Alabama, South Texas and
Gulf Coast markets. The Ark-La-Tex and Mississippi/Alabama markets are served by
the Ark-La-Tex Division, while the South Texas and Gulf Coast market areas are
served by an operating division of the Company. The Company believes it
currently has the leading market position in its Gulf Coast and South Texas
markets and the second leading position in its Ark-La-Tex market. Two smaller,
non-strategic divisions operated by the Company were recently disposed of by the
Company. These were the Indrillers Division which operated primarily in Michigan
and the Eastern Division which operated primarily in Ohio. See "--Recent
Acquisitions and Sales" above.

Ark-La-Tex Division. The Ark-La-Tex Division provides drilling services
primarily in Northeast Texas, Northern Louisiana, Southern Arkansas, Mississippi
and Alabama and currently markets a fleet of 37 rigs. The majority of the
drilling in the Ark-La-Tex market is directed to three of the five principal
target geologic formations in the region, generally located at depths ranging
from 8,900 to 13,000 feet. For these target formations, 450 to 1,000 horsepower
mechanical rigs are typically utilized in the Ark-La-Tex market. Twenty-three of
the divisions's rigs are suited for drilling to these depths, 18 of which are
mechanical, one of which is a diesel electric and four are SCR rigs. The other
two principal geologic targets in the market, the Austin Chalk and Pinnacle Reef
formations, are located at substantially greater depths, typically from 15,500
to 22,000 feet. The Company has 14 marketable rigs suitable for these target
depths. Three of these deep drilling rigs are 1,500 horsepower mechanical rigs
capable of drilling to 20,000 feet, three are diesel electric 1,500 and 2,000
horsepower rigs capable of drilling to depths ranging from 20,000 to 25,000 feet
and eight are diesel electric SCR rigs ranging from 1,200 to 3,000 horsepower
and capable of drilling from 17,000 to 30,000 feet.

During 1997 approximately 76% of the division's revenues were generated
from daywork contracts, 4% from footage contracts and 20% from turnkey
contracts. The average revenues per rig day worked for the division during 1997
was $8,239 and its average rig utilization rate was 95%.

South Texas Division. The South Texas Division markets a fleet of 36
rigs consisting of 17 trailer mounted rigs with rated depth capacities ranging
from 9,500 to 14,000 feet, 12 diesel electric SCR rigs with rated depth
capacities from 12,000 to 25,000 feet and seven conventional mechanical rigs
with rated depth capacities ranging from 10,000 to 14,000 feet. The Company
believes that trailer mounted rigs and 1,500 to 2,000 horsepower diesel electric
SCR rigs are in highest demand in this market. Trailer mounted rigs are
relatively more mobile than conventional rigs, thus decreasing the time and
expense to the customer of moving the rig to and from the drillsite. Under
ordinary conditions, the Company's trailer mounted rigs are capable of drilling
an average of two 10,000 foot wells per month. The Company believes it operates
the largest trailer mounted rig fleet in this market. The South Texas Division
also operates a fleet of 35 trucks, which are used exclusively to move the
Company's rigs. Most drilling in this market is for natural gas at depths
ranging from 10,000 to 15,000 feet.

During 1997, approximately 61% of the division's revenues were
generated from daywork contracts, 15% from footage contracts and 24% from
turnkey contracts. The average revenues per rig day worked for the division
during 1997 was $9,395 and its average rig utilization rate was 97%.

Gulf Coast Division. The Gulf Coast Division's drilling services are
provided to operators in Southern Louisiana and along the Texas Gulf Coast. The
Gulf Coast Division's rig fleet consists of 32 drilling rigs, including nine
1,500 to 2,000 horsepower diesel electric rigs with rated depth capacities of
20,000 to 25,000 feet, thirteen 1,000 to 4,000 horsepower diesel electric SCR
rigs with rated depth capacities of 15,000 to 40,000 feet and ten mechanical
rigs with rated depth capacities of 10,000 to 20,000 feet.

-5-

6



This division's rig fleet is comprised primarily of rigs acquired in
the GWDC Acquisition. Since the acquisition date, approximately 85% of its
revenues have been generated from daywork contracts, 1% from footage contracts
and 14% from turnkey contracts. Average revenue per day generated by the Gulf
Coast Division during 1997 was $10,219, and for the same period its average rig
utilization rates was 96%.

FOREIGN OPERATIONS

At the present time, the Company's foreign operations are in the
Venezuelan market having withdrawn from both the Argentine and Mexican markets
during 1996.

The Company began operating in Venezuela in 1994, and has upgraded the
performance capabilities of its rig fleet in Venezuela and is intensifying its
marketing efforts there in response to increased demand for land rig drilling
services. The Company currently has two rigs working in Venezuela and is
actively marketing its four remaining rigs. The Company believes this demand has
resulted principally from changes in Venezuelan government policies and
legislation encouraging private sector participation in oil and gas exploration
and production. In recent years, the Venezuelan national oil company, Petroleos
de Venezuela, S.A. ("PDVSA"), has permitted international oil companies to enter
into operating agreements with one of PDVSA's three main operating subsidiaries
to rehabilitate, reactivate and develop certain of its older fields.
Additionally, the Venezuelan government has enacted legislation enabling
multinational oil companies to conduct exploration and development operations in
Venezuela through production sharing arrangements with PDVSA and its
subsidiaries. Through August 1997, eight large undeveloped properties have been
awarded to multinational oil companies for development through production
sharing agreements. In June 1997, PDVSA awarded operating agreements to private
companies for the rehabilitation, reactivation and development of 18 additional
areas. The new operating agreements referred to by PDVSA as the "Third Operating
Round" cover 12 areas described by PDVSA as "onshore" locations covering a
combined area of approximately 2,600 square kilometers (approximately 1,000
square miles). The Company believes that the Third Operating Round operations
will require drilling and workover rigs with depth ratings from 4,000 to 18,000
feet.

Drilling contractors operating in Venezuela generally obtain contracts
through a bidding process open only to drilling contractors previously approved
for inclusion on the "bid list" of the customer and PDVSA. Drilling contracts
are sometimes awarded on a long-term basis, for periods of up to 24 months. In
the Company's experience, bid specifications for Venezuelan drilling contracts
typically require premium quality, intermediate and deep drilling rigs with
1,500 to 3,000 horsepower ratings equipped with top drive mechanisms.

In 1996, the Company identified certain management and operating
deficiencies that contributed to reduced operations and profits, and the removal
of the Company from PDVSA's bid list due to the failure of the Company's
Venezuelan subsidiary to file statutorily required financial reports with the
Venezuelan government. To address these problems, the Company replaced its local
management with new management having substantial experience with competing
drilling contractors in Venezuela. The Company has since been restored to
PDVSA's bid list.

The Venezuela Division is currently marketing four land drilling rigs
with rated depths of 10,000 to 15,000 feet and two workover rigs, of which two
drilling rigs are under contract and the remainder are idle. To improve the
marketability of its existing Venezuelan rig fleet, the Company completed $3.6
million of capital improvements to its rigs in 1997. The Venezuela Division
generally provides its drilling services under daywork contracts and workover
services under hourly contracts. Hourly contracts call for the Company to
provide a rig and crew, for which it is paid on an hourly basis. Historically,
the Venezuela Division has contracted to provide crews to man rigs owned by
PDVSA and may do so in the future.

Further expansion of the Company's drilling fleet in Venezuela will
depend primarily on whether the Company is successful in obtaining long-term
drilling contracts in that market and on a variety of other factors including
market conditions, management's assessment of existing and future demand,
commodity prices and day rates. Should the Company be awarded long-term drilling
contracts requiring additional drilling rigs, management expects that inventory
rigs or active rigs from its domestic fleet will be refurbished and upgraded to
meet the premium quality rig specifications typically required by such long-term
international drilling contracts.

Foreign operations contributed approximately 3%, 36%, and 53% of the
Company's operating revenues for the years ended December 31, 1997, 1996 and
1995, reduced operating income by 9% in 1997 and accounted for 71% and 68%,
respectively, of the Company's total losses from operations for 1996 and 1995.
During 1997, the Company's

-6-

7



foreign operations were conducted in Venezuela. In 1996 and 1995 the Company had
operations in Mexico and South America.

Consistent with the Company's decision to redeploy its rigs to more
productive markets, the Company withdrew from both the Argentine and Mexican
markets in 1996. All four of the Company's drilling rigs previously located in
Mexico have been returned to the United States. Of the four repatriated rigs,
three have been refurbished and placed in service in the Company's Ark-La-Tex or
South Texas Divisions and one is held for sale. In April 1997, the Company sold
three of its six drilling rigs and certain other assets located in Argentina for
$1.5 million. The remaining three rigs have been returned to the United States
where two of the three have been refurbished and returned to service in the
South Texas Division and one is being held for refurbishment and reactivation.

Although current operations are in Venezuela, the Company has and will
consider expansion into additional selected international markets as bidding
opportunities arise. In this regard, the Company intends to bid on long-term
contracts for drilling in Bolivia and Saudi Arabia.

RIG INVENTORY AND REFURBISHMENTS

As of March 23, 1998, the Company has an inventory of 15 rigs, or
approximately 12% of its rig fleet, which are suitable for refurbishment and
reactivation to meet future demand. The Company considers "inventory rigs" to be
rigs that are not working, are not actively marketed and that require additional
capital expenditures to return them to service. Management believes that the
anticipated demand for land drilling rigs in the Company's Ark-La-Tex, Gulf
Coast, South Texas and Venezuelan markets justifies a program to restore certain
of its inventory rigs to marketable condition.

Since the fourth quarter of 1996, the Company has completed the
refurbishment of 26 rigs at an aggregate cost of approximately $58.1 million. Of
these 26 recently refurbished rigs, 21 were diesel electric SCR inventory rigs
ranging from 1,000 to 4,000 horsepower with depth ratings of 15,000 to 40,000
feet. The other five refurbished rigs were previously marketed rigs that were
returned to the U.S. following the Company's withdrawal from the Argentine and
Mexican markets in late 1996. These rigs are mechanical rigs, ranging from 750
to 1,000 horsepower with rated depth capacities of 9,500 to 15,000 feet. All 26
recently refurbished rigs are now assigned to the Company's Ark-La-Tex, Gulf
Coast and South Texas Divisions.

As of March 23, 1998, the Company is refurbishing three rigs from its
inventory, of which two are diesel electric SCR rigs and one is a mechanical
rig. The mechanical rig is rated at 1,500 horsepower with a depth rating of
20,000 feet. The diesel electric SCR rigs undergoing refurbishment are 1,000 to
2,000 horsepower rigs with depth ratings of 15,000 to 25,000 feet. The Company
presently anticipates that the refurbished rigs will be deployed to the
Company's Ark-La-Tex, South Texas and Gulf Coast markets.

The Company plans to refurbish the remaining 12 inventory rigs during
late 1998 and 1999 as demand warrants. Upon refurbishment the rigs are expected
to be reactivated for service in the Company's four core domestic markets. If,
however, the Company is successful in obtaining long-term drilling contracts in
Venezuela or other foreign locations, certain of the Company's inventory rigs or
active rigs may be refurbished and mobilized for service in those foreign
markets. Refurbishment costs for rigs deployed by the Company in its core
domestic markets averaged approximately $2.2 million per rig for rigs
refurbished in 1996 and 1997 and are estimated to be $2.5 million per rig for
those to be refurbished in 1998 and 1999. Refurbishment costs for 2,000 and
3,000 horsepower rigs for the Venezuelan market are estimated to average
approximately $12.0 million per rig, in each case including the cost of a new
drill string. The actual number of rig refurbishments completed by the Company,
however, will depend on many factors, including management's assessment of
existing and anticipated demand and day rates, the Company's success in bidding
for foreign and domestic drilling contracts and possible future acquisitions of
rigs. See "Certain Risks --Dependence on Oil and Gas Industry; Industry
Conditions"

CONTRACTS

The Company's contracts for drilling oil and gas wells are obtained
either through competitive bidding or as a result of negotiations with
customers. Contract terms offered by the Company are generally dependent on the
complexity and risk of operations, on-site drilling conditions, type of
equipment used and the anticipated duration of the work to be performed.
Generally, domestic drilling contracts are for a single well, while foreign
drilling contracts

-7-

8



are for multiple wells or a specified term. The contracts typically obligate the
Company to pay certain operating expenses, including wages of drilling
personnel, maintenance expenses, incidental rig supplies, equipment and local
office facilities. Domestic drilling contracts are typically subject to
termination by the customer on short notice, usually upon payment of a fee.
Foreign drilling contracts generally require longer notice periods for
termination and may also require that the customer pay for the mobilization and
demobilization costs. The Company's drilling contracts generally provide for
compensation on either a daywork, turnkey or footage basis.

Daywork Contracts. Under daywork drilling contracts, the Company
provides a drilling rig with required personnel to the operator, who supervises
the drilling of the well. The Company is paid based on a negotiated fixed rate
per day while the rig is utilized. Daywork drilling contracts generally specify
the type of equipment to be used, the size of the hole and the depth of the
well. Under a daywork drilling contract, the customer bears a large portion of
out-of-pocket costs of drilling and the Company generally bears no part of the
usual capital risks associated with oil and gas exploration (such as time delays
for various reasons, including stuck drill pipe and blowout).

Turnkey Contracts. Under a turnkey contract, the Company contracts to
drill a well to an agreed-upon depth under specified conditions for a fixed
price, regardless of the time required or the problems encountered in drilling
the well. The Company provides technical expertise and engineering services, as
well as most of the equipment required for the well, and is compensated when the
contract terms have been satisfied. Turnkey contracts afford an opportunity to
earn a higher return than would normally be available on daywork or footage
contracts if the contract can be completed successfully without complications.

The risks to the Company under a turnkey contract are substantially
greater than on a well drilled on a daywork basis because the Company assumes
most of the risks associated with drilling operations generally assumed by the
operator in a daywork contract, including the risk of blowout, loss of hole,
stuck drill pipe, machinery breakdowns, abnormal drilling conditions and risks
associated with subcontractors' services, supplies, cost escalation and
personnel. The Company employs or contracts for engineering expertise to analyze
seismic, geologic and drilling data to identify and reduce many of the drilling
risks assumed by the Company. Management uses the results of this analysis to
evaluate the risks of a proposed contract and seeks to account for such risks in
its bid preparation. The Company believes that its operating experience,
qualified drilling personnel, risk management program, internal engineering
expertise and access to proficient third party engineering contractors have
allowed it to reduce the risks inherent in turnkey drilling operations. The
Company also maintains insurance coverage against some but not all drilling
hazards.

Footage Contracts. Under footage contracts, the Company is paid a fixed
amount for each foot drilled, regardless of the time required or the problems
encountered in drilling the well. The Company pays more of the out-of-pocket
costs associated with footage contracts compared with daywork contracts. Similar
to a turnkey contract, the risks to the Company on a footage contract are
greater because it assumes most of the risks associated with drilling operations
generally assumed by the operator in a daywork contract, including the risk of
blowout, loss of hole, stuck drill pipe, machinery breakdowns, abnormal drilling
conditions and risks associated with subcontractors' services, supplies, cost
escalation and personnel. As with turnkey contracts, the Company manages this
additional risk through the use of engineering expertise and bids the footage
contracts accordingly. The Company also maintains insurance coverage against
certain drilling hazards.

CUSTOMERS AND MARKETING

The Company's contract drilling customers include independent
producers, major oil companies and national petroleum companies. The Company
believes that approximately 85% of the wells it drilled in 1997 were principally
targeted by its customers for production of natural gas rather than crude oil.
One unaffiliated customer accounted for 10% of the Company's revenues for the
year ended December 31, 1997. There were no such significant customers for the
years ended December 31, 1996 and 1995.

The Company primarily markets its drilling rigs on a regional basis
through employee sales representatives. These sales representatives utilize
personal contracts and industry periodicals and publications to determine which
operators are planning to drill oil and gas wells in the immediate future. Once
the Company has been placed on the "bid list" for an operator, the Company will
typically be given the opportunity to bid on all future wells for that operator
in the area.


-8-

9



The Company from time to time enters into informal, nonbinding
commitments with its customers to provide drilling rigs for future periods at
agreed upon rates plus fuel and mobilization charges, if applicable, and
escalation provisions. This practice is customary in the land drilling business
during times of tightening rig supply. Although neither the Company nor the
customer is legally required to honor these commitments, the Company strives to
satisfy such commitments in order to maintain good customer relations.

EMPLOYEES

At March 15, 1997, the Company had approximately 3,000 employees. None
of the Company's domestic employees are subject to collective bargaining
agreements, and management believes its employee relations are satisfactory.

REGULATION

Many aspects of the Company's operations are affected by domestic and
foreign political developments and are subject to numerous laws and regulations
that may relate directly or indirectly to the contract drilling industry. For
example, drilling operations are subject to extensive and evolving laws and
regulations governing environmental quality, pollution control, remediation of
contamination and preservation of natural resources. Such laws and regulations
pertain, among other things, to air emissions, waste management, spills and
other discharges, wetlands and endangered species protection and cleanup of
contamination. The Company's operations are often conducted in or near
ecologically sensitive areas such as wetlands which are subject to protective
measures. The handling of waste materials, some of which are classified as
hazardous substances, is a routine part of the Company's operations.
Consequently, the regulations applicable to the Company's operations include
those with respect to containment, disposal and control of the discharge of
hazardous oilfield waste and other nonhazardous waste material into the
environment, requiring removal and cleanup under certain circumstances, or
otherwise relating to the protection of the environment. Laws and regulations
protecting the environment have become more stringent in recent years and may in
certain circumstances impose strict liability, rendering a party liable for
environmental damage without regard to negligence or fault on the part of such
party. Such laws and regulations may expose the Company to liability for the
conduct of, or conditions caused by, others or for acts of the Company which
were in compliance with all applicable laws at the time such acts were
performed. The Company may also be exposed to environmental or other liabilities
originating from businesses and assets subsequently acquired by the Company.
Compliance with such laws and regulations may require significant capital
expenditures. Although such compliance costs to date have not had a material
effect on the Company, application of these requirements or the adoption of new
requirements could have a material adverse effect on the Company. In addition,
the modification or judicial interpretation of existing laws or regulations or
the adoption of new laws or regulations curtailing exploratory or development
drilling for oil and gas for economic, environmental or other reasons could have
a material adverse effect on the Company's operations by limiting future
contract drilling opportunities.

Environmental regulation has led to higher drilling costs, a more
difficult and lengthy well permitting process and, in general, has adversely
affected many oil companies' drilling decisions. The primary environmental
statutory and regulatory programs that affect the Company's operations include
those summarized below.

Oil Pollution Act and Clean Water Act. The Oil Pollution Act of 1990
("OPA") amends certain provisions of the Federal Water Pollution Control Act of
1972, commonly referred to as the Clean Water Act ("CWA"), and other statutes as
they pertain to the prevention of and response to hazardous substances and oil
spills into navigable waters. OPA requires responsible parties to maintain proof
of financial responsibility to cover some portion of the cost of a potential
spill and to prepare an oil spill contingency plan. Under OPA, a person owning
or operating a facility or equipment from which there is a discharge or threat
of a discharge of oil into or upon navigable waters or adjoining shorelines is
liable as a "responsible party" for removal costs and damages. Many of the
Company's activities are conducted in or near ecologically sensitive areas, such
as wetlands, coastal environment and inland waterways. An oil spill in a wetland
or inland waterway could produce substantial damage to the environment,
including wildlife and natural resources, and result in material liability.
Federal law imposes strict, joint and several liability on facility owners for
containment and clean-up costs and certain other damages, including natural
resource damages, arising from a spill as well as civil and criminal penalties
for violation of regulatory requirements.

The CWA also regulates the discharge of pollutants to surface water and
the discharge of dredged or fill material to wetlands areas.


-9-

10



Superfund. The Comprehensive Environmental Response, Compensation and
Liability Act ("CERCLA"), commonly referred to as the "Superfund" law, imposes
strict, joint and several liability on certain classes of persons with respect
to the release or threatened release of a hazardous substance to the
environment. These persons include: (i) the current owner and operator of a
facility from which hazardous substances are released; (ii) owners and operators
of a facility at the time any hazardous substances were disposed; (iii)
generators of hazardous substances who arranged for treatment or disposal at or
transport to such facility and (iv) transporters who selected the facility for
treatment or disposal of hazardous substances. The Company may be responsible
under CERCLA for all or part of the costs to clean up sites at which hazardous
substances have been released. To date, however, the Company has not been named
a potentially responsible party under CERCLA or any similar state Superfund
laws.

Hazardous Waste Disposal. The Company's operations involve the
generation or handling of materials that are classified as hazardous waste, and
that are subject to the Federal Resource Conservation and Recovery Act ("RCRA")
and comparable state statues. The Environmental Protection Agency and various
state agencies have imposed strict requirements regulating the treatment,
storage, transport and disposal of hazardous wastes.

NORM. Oil and gas exploration and production activities have been
identified as generators of naturally-occurring radioactive materials ("NORM").
The generation, handling and disposal of NORM waste due to oil and gas
exploration and production activities is currently regulated in various states
including Louisiana and Texas. The Company does not believe that its compliance
with such regulations will have a material effect on its operations or financial
condition, but there can be no assurance in this regard.

Occupational Safety and Health. The Occupational Safety and Health Act
of 1970, as amended, ("OSHA") establishes employer responsibilities including
maintenance of a workplace free of recognized hazards likely to cause death or
serious injury, compliance with standards promulgated by the Occupational Safety
and Health Administration, and various recordkeeping, disclosure and procedural
requirements. Such requirements include, for example, the Hazard Communication
Standard which applies to all private-sector employers including those in the
oil and gas exploration and production industry, and requires such employers to
assess chemical hazards, obtain and maintain certain written descriptions of
these hazards, develop a hazard communication program and train employees to
work safely with chemicals on site. Failure to comply with the requirements of
OSHA may result in administrative, civil and criminal penalties. The Company
believes it is in substantial compliance with OSHA requirements and does not
believe it will be required to expend material amounts by reason of such
requirements. However, the Company is unable to predict the ultimate cost of
compliance with these changing requirements.

INSURANCE

The Company's operations are subject to the many hazards inherent in
the drilling business, including, for example, blowouts, cratering, fires,
explosions and adverse weather. These hazards could cause personal injury,
suspend drilling operations or seriously damage or destroy the equipment
involved and could cause substantial damage to producing formations and
surrounding areas. Damage to the environment could also result from the
Company's operations, particularly through oil spillage and extensive,
uncontrolled fires. As a protection against operating hazards, the Company
maintains insurance coverage, including property casualty insurance on its rigs
and drilling equipment, comprehensive general liability and commercial contract
indemnity (including a separate policy for foreign liability), commercial
umbrella and workers' compensation insurance and "control of well" insurance.

The Company's insurance coverage for property damage to its rigs and
drilling equipment is based on the Company's estimate, as of June 1997, of the
cost of comparable used equipment to replace the insured property. There is an
annual aggregate deductible on rigs of $500,000 to be comprised of losses
otherwise recoverable thereafter in excess of a $50,000 maintenance deductible.
There is a $10,000 deductible per occurrence on equipment.

The Company's third party liability insurance coverage under each of
the general and foreign policies is $1.0 million per occurrence, with a
deductible of $50,000 per occurrence. The Company believes that it is adequately
insured for public liability and property damage to others with respect to its
operations. However, such insurance may not be sufficient to protect the Company
against liability for all consequences of well disasters, extensive fire damage
or damage to the environment.

The Company also maintains insurance coverage to protect against
certain hazards inherent in its turnkey contract drilling operations. This
insurance covers "control of well" (including blowouts above and below the
surface),


-10-

11



cratering, seepage and pollution and care, custody and control. The Company's
current insurance provides $500,000 coverage per occurrence for care, custody
and control, and coverage per occurrence for control of well, cratering, seepage
and pollution associated with drilling operations of either $10.0 million or
$20.0 million, depending upon the area in which the well is drilled and its
target depth. Each form of coverage provides for a deductible for the account of
the Company, as well as a maximum limit of liability. Each casualty is an
occurrence, and there may be more than one such occurrence on a well, each of
which would be subject to a separate deductible.

CERTAIN RISKS

Dependence on Oil and Gas Industry; Industry Conditions. The Company's
business and operations are substantially dependent upon conditions in the oil
and gas industry and, specifically, the exploration and production expenditures
of oil and gas companies. The demand for contract land drilling and related
services is directly influenced by oil and gas prices, expectations about future
prices, the cost of producing and delivering oil and gas, government
regulations, local and international political and economic conditions,
including the ability of the Organization of Petroleum Exporting Countries
("OPEC") to set and maintain production levels and prices, the level of
production by non-OPEC countries and the policies of the various governments
regarding exploration and development of their oil and gas reserves. During
1997, conditions in the oil and gas industry were such that demand for land
drilling services was generally strong in each of the Company's four core
domestic markets. The Company's 1997 average rig utilization rate for these four
core markets was approximately 96%. In the first quarter of 1998, however, this
average rig utilization rate was approximately 80%. This lower average
utilization rate is believed by the Company to be due to an overall weakening of
demand it its core markets for land drilling services and, to a lesser extent,
delays caused by inclement weather. The generally reduced demand for land
drilling services in the first quarter of 1998 is believed by the Company to be
attributable to the decline of prices for oil production, and to widespread
uncertainty among potential customers as to the future level and trend of oil
and gas prices. If these industry conditions persist or worsen, they could have
a material adverse effect on the Company's financial condition and results of
operations.

History of Losses from Operations. Although the Company had net income
of $10.2 million for the year ended December 31, 1997, the Company has a history
of losses and had previously not had a profitable full year since 1991. The
Company incurred net losses of $11.7 million and $13.4 million for the years
ended December 31, 1996 and 1995, respectively. The 1996 loss included
non-recurring charges of $6.1 million while the 1995 loss included a provision
for asset impairment of $5.3 million. Profitability in the future will depend
upon many factors, but largely upon utilization rates and day rates for the
Company's drilling rigs. There can be no assurance that current utilization
rates and day rates will not decline or that the Company will not experience
losses.

Risks of International Operations. The Company derives revenue from
international operations. The Company's current international operations are
conducted only in Venezuela; however, the Company is pursuing opportunities in
other countries, including Bolivia and Saudi Arabia. Risks associated with
operating in international markets include foreign exchange restrictions and
currency fluctuations, foreign taxation, political instability, foreign and
domestic monetary and tax policies, expropriation, nationalization,
nullification, modification or renegotiation of contracts, war and civil
disturbances or other risks that may limit or disrupt markets. Additionally, the
ability of the Company to compete in the international drilling markets may be
adversely affected by foreign government regulations that favor or require the
awarding of such contracts to local contractors, or by regulations requiring
foreign contractors to employ citizens of, or purchase supplies from, a
particular jurisdiction. Furthermore, the Company's foreign subsidiaries may
face governmentally imposed restrictions from time to time on their ability to
transfer funds to the Company. No predictions can be made as to what foreign
governmental regulations may be applicable to the Company's operations in the
future. The Company is currently marketing six rigs in Venezuela, two of which
are under contract. In addition, during 1997 the Company completed approximately
$3.6 million in capital improvements to its rigs located in Venezuela. There can
be no assurance that these marketing efforts and capital improvements will
improve the Company's operating performance or generate contracts for the
Company's rigs in Venezuela.

Risks of Acquisition Strategy. As a key component of its new business
strategy, the Company has pursued and intends to continue to pursue acquisitions
of complementary assets and businesses. Certain risks are inherent in an
acquisition strategy, such as increasing leverage and debt service requirements
and combining disparate company cultures and facilities, which could adversely
affect the Company's operating results. The success of any completed acquisition
will depend in part on the Company's ability to integrate effectively the
acquired business into the Company. The process of integrating such acquired
business may involve unforeseen difficulties and may require a disproportionate
amount of management's attention and the Company's financial and other
resources. Possible future


-11-

12



acquisitions may be for purchase prices significantly higher than those paid for
recent and pending acquisitions. No assurance can be given that the Company will
be able to continue to identify additional suitable acquisition opportunities,
negotiate acceptable terms, obtain financing for acquisitions on satisfactory
terms or successfully acquire identified targets. The Company's failure to
achieve consolidation savings, to incorporate the acquired business and assets
into its existing operations successfully or to minimize any unforeseen
operational difficulties could have a material adverse effect on the Company's
financial condition and results of operations.

Dependence on Key Personnel; New Business Strategy. The Company
believes that its operations are dependent upon a small group of relatively new
management personnel, the loss of any one of whom could have a material adverse
effect on the Company's financial condition and results of operations. Material
changes in the Company's management and business strategy have only recently
occurred. The Company is therefore unable to predict the effect of these changes
on the Company's financial condition and results of operations. The Company's
ability to meet its substantially increased debt service and principal payments
will depend, in part, on the success of the Company's new business strategy.
There can be no assurance these material changes in the Company's management and
business strategy will result in the improvement of the Company's financial
condition and results of operations.

Competition. The land drilling industry is a highly competitive and
cyclical business characterized by high capital and maintenance costs. Drilling
contracts are usually awarded on a competitive basis and, while an operator may
consider factors such as quality of service and type and location of equipment
as well as the ability to provide ancillary services, price and rig availability
are the primary factors in determining which contractor is awarded a job. An
increasingly important competitive factor in the land drilling industry is the
ability to provide drilling equipment adaptable to, and personnel familiar with,
new technologies and drilling techniques as they become available. The land
drilling business is also highly fragmented. As a result, even though the
Company has the largest or second largest rig fleet in its four core domestic
markets, the Company estimates that its market share represents only 16% to 35%
of the overall market share in each of these four core markets. Certain of the
Company's competitors have greater financial and human resources than the
Company, which may enable them to better withstand periods of low rig
utilization, to compete more effectively on the basis of price and technology,
to build new rigs or acquire existing rigs and to provide rigs more quickly than
the Company in periods of high rig utilization. A number of the Company's
competitors have also announced plans to refurbish and reactivate rigs from
their inventory of stacked rigs. The deployment of these additional rigs to the
Company's core markets could further intensify competition based on pricing and
rig availability. There can be no assurance that the Company will be able to
compete successfully against all its competitors in the future or that the level
of competition will allow the Company to obtain adequate margins from its
drilling services.

Turnkey Drilling Risk. Contract drilling services performed under
turnkey drilling contracts have historically represented, and are expected to
continue to represent, a significant component of the Company's revenues. Under
a turnkey drilling contract, the Company contracts to drill a well to a contract
depth under specified conditions for a fixed price. In addition, the Company
provides technical expertise and engineering services, as well as most of the
equipment required for the well, and is compensated when the contract terms have
been satisfied. On a turnkey well, the Company often subcontracts for related
services and manages the drilling process. The risks to the Company on a turnkey
drilling contract are substantially greater than on a well drilled on a daywork
basis because the Company assumes most of the risks associated with drilling
operations generally assumed by the operator in a daywork contract, including
risk of blowout, loss of hole, stuck drill string, machinery breakdowns,
abnormal drilling conditions and risks associated with subcontractors' services,
supplies and personnel. Although the Company has obtained insurance coverage in
the past to reduce certain of the risks inherent in turnkey drilling operations,
there can be no assurance that such coverage will be obtained or available in
the future. The occurrence of an uninsured or under-insured loss could have a
material adverse effect on the Company's financial position and result of
operations.

Shortages of Equipment, Supplies and Personnel. There is a general
shortage of drilling equipment and supplies which the Company believes may
intensify. The cost and delivery times of equipment and supplies are
substantially greater than in prior periods and are currently escalating.
Accordingly, in 1996 the Company formed an alliance with a drill pipe
manufacturer that enables the Company to take delivery through 1998 of agreed
maximum


-12-

13



quantities of drill pipe in commonly used diameters at fixed prices, plus
possible escalations for increases in the manufacturer's cost of raw materials.
Due in part to its alliance arrangement, the Company is not currently
experiencing any material shortages of, or material price increases in, drill
pipe. The Company believes that the alliance may reduce, but not eliminate, its
exposure to price increases and supply shortages of drill pipe. The Company and
its supplier under the drill pipe alliance have entered into a formal
contractual arrangement for the purchase and supply of an average quarterly
quantity of 3,750 joints of drill pipe (a total of 15,000 joints) during 1999 at
prices based on the supplier's price list as of February 1997 less 5% (the
"Drill Pipe Agreement"). If the Company's source of supply through the alliance
and the Drill Pipe Agreement becomes unavailable or insufficient for any reason
(including by reason of additional rig acquisitions), the Company will likely
experience substantial delays in, and material price increases for, obtaining
substitute or additional supplies of drill pipe. Additionally, the Company may
be subject to shortages and price increases with respect to quantities in excess
of, and varieties of drill pipe not covered by, the alliance and the Drill Pipe
Agreement. Although the Company has formed similar informal supply alliances
with manufacturers and suppliers of other equipment and supplies, and is
attempting to establish arrangements to assure adequate availability of certain
other necessary equipment and supplies on satisfactory terms, there can be no
assurance that it will be able to do so. Shortages by the Company of drilling
equipment or supplies could delay and adversely affect its ability to refurbish
its inventory rigs and obtain contracts for its marketable rigs, which could
have a material adverse effect on its financial condition and results of
operations.

The demand for and wage rates of, qualified rig crews have begun to
rise in the land drilling industry in response to the increasing number of
active rigs in service. Although the Company has not encountered material
difficulty in hiring and retaining qualified rig crews, such shortages have in
the past occurred in the industry and are again arising as demand for land
drilling services increases. The Company may experience shortages of qualified
personnel to operate its rigs, which could have a material adverse effect on the
Company's financial condition and results of operations.

Governmental Regulations and Environmental. Many aspects of the
Company's operations are affected by domestic and foreign political developments
and are subject to numerous laws and regulations that may relate directly or
indirectly to the contract drilling industry. The Company's operations are often
conducted in or near ecologically sensitive areas, such as wetlands, which are
subject to protective measures. Such laws and regulations may expose the Company
to liability for the conduct of, or conditions caused by, others or for acts of
the Company which were in compliance with all applicable laws at the time such
acts were performed. The Company may also be exposed to environmental or other
liabilities originating from businesses and assets subsequently acquired by the
Company. Compliance with such laws and regulations may require significant
capital expenditures. Although such compliance costs to date have not had a
material effect on the Company, application of these requirements or the
adoption of new requirements could have a material adverse effect on the
Company. In addition, the modification or judicial interpretations of existing
laws or regulations or the adoption of new laws or regulations curtailing
exploratory or development drilling for oil and gas for economic, environmental
or other reasons could have a material adverse effect on the Company's
operations by limiting future contract drilling opportunities.

Significant Leverage and Debt Service Requirements. On June 27, 1997,
the Company issued $175.0 million of 87/8 Senior Notes due 2007 in an
underwritten public offering (the "Senior Notes"). Additionally, the Company has
a $50.0 million amended and restated senior secured revolving credit facility
with a syndicate of commercial banks (the "Bank Credit Facility") under which no
indebtedness was outstanding at December 31, 1997, due to the repayment of all
amounts then outstanding from the net proceeds of a common stock offering. The
Company expects, however, to continue to borrow under the Bank Credit Facility
and possible future credit arrangements in order to finance possible future
acquisitions and for general corporate purposes. In January 1998, the Company
borrowed $28 million in order to complete the Murco Acquisition under the Bank
Credit Facility.

The level of the Company's indebtedness could have several important
effects on its future operations, including, among others, (i) its ability to
obtain additional financing for working capital, acquisitions, capital
expenditures, general corporate and other purposes may be limited, (ii) a
substantial portion of the Company's cash flow from operations will be dedicated
to the payment of principal and interest on its indebtedness, thereby reducing
funds available for other purposes and (iii) the Company's significant leverage
could make it more vulnerable to economic downturns in the industry. The
Company's ability to meet its debt service obligations and reduce its total
indebtedness will be dependent upon the Company's future performance, which will
be subject to the success of its business strategy, general economic conditions,
industry cycles, levels of interest rates, and financial, business and other
factors affecting the operations of the Company, many of which are beyond its
control. There can be no assurance that the Company's


-13-

14



business will generate sufficient cash flow from operations to meet debt service
requirements and payments of principal, and if the Company is unable to do so,
it may be required to sell assets, to refinance all or a portion of its
indebtedness, including the Senior Notes, or to obtain additional financing.
There can be no assurance that any such refinancing would be possible or that
any additional financing could be obtained.

Restrictions Imposed by Terms of Indebtedness. The indenture under
which the Senior Notes were issued (the "Indenture") contains covenants
restricting or limiting the ability of the Company and certain of its
subsidiaries to, among other things: (i) incur additional indebtedness; (ii) pay
dividends or make other restricted payments; (iii) make asset dispositions; (iv)
permit liens; (v) enter into sale and leaseback transactions; (vi) enter into
certain mergers, acquisitions and consolidations; (vii) make certain
investments; (viii) enter into transactions with related persons and (ix) engage
in unrelated lines of business.

In addition, the loan agreement setting forth the terms of the Bank
Credit Facility (the "Bank Credit Agreement") contains certain other and more
restrictive covenants than those contained in the Indenture. These covenants may
adversely affect the Company's ability to pursue its acquisition and rig
refurbishment strategies and limit is flexibility in responding to changing
market conditions. The Bank Credit Agreement also requires the Company to
maintain specific financial ratios and satisfy certain financial condition
tests. The Company's ability to meet those financial ratios and financial
condition tests can be affected by events beyond its control, and there can be
no assurance that the Company will meet those tests. The Bank Credit Agreement
contains default terms that effectively cross default with the Indenture.
Accordingly, the breach by the Company or its subsidiaries of the covenants
contained in the Indenture likely will result in a default under not only the
Indenture but also the Bank Credit Facility, and possibly certain other then
outstanding debt obligations of the Company or its subsidiaries. If the
indebtedness under the Bank Credit Facility or other indebtedness of the Company
or its subsidiaries is in excess of $10.0 million and is not paid when due or is
accelerated by the holders thereof, an event of default under the Indenture
would occur. In any such case, there can be no assurance that the Company's
assets would be sufficient to repay in full all of the Company's and its
subsidiaries' indebtedness, including the Senior Notes.

Qualification of the GWDC Acquisition as a Reorganization for U.S.
Federal Tax Purposes. The GWDC Acquisition is intended to qualify as a tax free
reorganization under Sections 368(a)(1)(A) and 368(a)(2)(D) of the Internal
Revenue Code of 1986, as amended (the "Code"), with respect to common stock
received by GWDC shareholders. A principal condition for such qualification is
that the former shareholders of GWDC will satisfy the continuity of proprietary
interest standard with respect to common stock received in the GWDC Acquisition.
Thus, under present Internal Revenue Service ("IRS") guidelines, dispositions of
common stock by GWDC shareholders during the five years following the GWDC
Acquisition could cause the IRS to assert that the GWDC Acquisition does not
qualify as a tax free reorganization. The Company has no contractual agreements
with GWDC shareholders preventing the disposition of their shares. If the GWDC
Acquisition fails to qualify as a tax free reorganization for failure to meet
the continuity of interest standard or for any other reason, the receipt of
common stock will be taxable to the GWDC shareholders at the time of the GWDC
Acquisition, and GWDC will be deemed to have sold all of its assets in a taxable
exchange triggering a corporate tax liability to GWDC estimated to be in excess
of $30.0 million. The Company's wholly-owned subsidiary, Grey Wolf Drilling
Company (formerly Drillers, Inc.), as the surviving corporation of the GWDC
Acquisition, would be liable for any such corporate tax which, if imposed, would
have a material adverse effect on the financial condition of the Company

ITEM 2. PROPERTIES

DRILLING EQUIPMENT

A land drilling rig consists of engines, drawworks, a mast,
substructure, pumps to circulate drilling fluid, blowout preventers, drill
string and related equipment. The actual drilling capacity of a rig may be less
than its rated drilling capacity due to numerous factors, including the length
of its drill string. The intended well depth and the drill site conditions
determine the drill string length and other equipment needed to drill a well.
Generally, land rigs operate domestically with crews of five to six persons and
in Venezuela with crews of ten to 12 persons.

The Company's rig fleet consists of several rig types to meet the
demands of its customers in each of the markets it serves. The Company's rig
fleet consists of two basic types of drilling rigs, the mechanical and the
diesel electric. Mechanical rigs transmit power generated by a diesel engine
directly to an operation (for example the


-14-

15



drawworks or mud pumps on a rig) through a compound consisting of chains, gears
and hydraulic clutches. Diesel electric rigs are further broken down into two
subcategories, direct current rigs and SCR rigs. Direct current rigs transmit
the power generated by a diesel engine to a direct current generator. This
direct current electrical system then distributes the electricity generated to
direct current motors on the drawworks and mud pumps. SCR rig's diesel engines
drive alternating current generators and this alternating current can be
transmitted to use for rig lighting and rig quarters or converted to direct
current to drive the direct current motors on the rig.

The following table summarizes the rigs owned by the Company at March
23, 1998, by maximum rated depth capacity:

The Company has never declared or paid cash dividends on its common
stock and does not expect to pay cash dividends in 1998 or for the foreseeable
future. The Company anticipates that all cash flow generated from operations in
the foreseeable future will be retained and used to develop or expand the
Company's business and reduce outstanding indebtedness. Any future payment of
cash dividends will depend upon the Company's results of operations, financial
condition, cash requirements and other factors deemed relevant by the Board of
Directors.

The terms of the Company's Bank Credit Facility prohibit the payment of
dividends without the prior written consent of the banks and the terms of the
Indenture under which the Senior Notes are issued also restrict the Company's
ability to pay dividends under certain conditions.

SHARES ELIGIBLE FOR FUTURE SALE

Approximately 41% of the outstanding common stock is available for
resale by selling shareholders under an effective shelf registration statement
(the "Resale Shelf") under the Securities Act of 1933, as amended (the
"Securities Act"). Approximately 9% of the outstanding common stock is not
covered by the Resale Shelf, but is available for resale under Rules 144 and 145
under the Securities Act and is covered to a substantial extent by currently
unexercised registration rights. An additional 5,135,400 shares are issuable
upon exercise of options and 489,600 shares are issuable upon the exercise of
warrants. Future sales of substantial amounts of common stock in the public
market, or the perception that such sales may occur, could adversely affect
prevailing market prices of the common stock.

On March 23, 1997, the last reported sales price of the Company's
common stock on the American Stock Exchange was $4.625 per share.

RECENT SALES OF UNREGISTERED SECURITIES

The only recent sale of unregistered securities was the 12.4 million
shares issued to acquire the operating assets of Flournoy Drilling Company on
January 31, 1997, which was disclosed previously in the Company's Form 10-Q for
the quarterly period ended March 31, 1997. These shares were subsequently
registered for resale under a shelf registration on Form S-3 that became
effective November 6, 1997.

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

The following discussion should be read in conjunction with the
consolidated financial statements of Grey Wolf, Inc. ("Grey Wolf" or the
"Company") included elsewhere herein. All significant intercompany transactions
have been eliminated.

GENERAL

The Company's operations have been and will continue to be
significantly affected by the new management team installed in 1996, the
implementation of a new business strategy in April 1996 and the major
transactions that have been consummated by the Company since August 1996. Since
the implementation of its new business strategy, the Company has acquired 100
drilling rigs and now has the largest or second largest active rig fleet in each
of its four core domestic markets, the Ark-La-Tex, Mississippi/Alabama, South
Texas and Gulf Coast markets. As of March 23, 1998 the Company's rig fleet
consists of 126 rigs, of which 111 are currently marketed by the Company.
Refurbishment and reactivation of the Company's inventory rigs is also a key
element of the Company's business strategy. From the fourth quarter of 1996
through February 1998, the Company has refurbished 26 rigs at an approximate
total cost of $58.1 million. Of the Company's inventory of 15 rigs, at March 23,
1998, three rigs are undergoing refurbishment and the Company intends to begin
refurbishment of the remaining 12 during 1998 and 1999. The Company estimates
total costs for pending and planned refurbishments will total approximately
$37.5 million, of which $1.6 million had been expended at December 31, 1997. By
increasing the size of its rig fleet through acquisitions and refurbishments,
the Company has increased its market share in its four core domestic markets
during a period of rapidly rising demand and


-17-

18



day rates for land drilling rigs in those key markets. The combined effect of
the Company's larger fleet of marketable rigs, higher rig utilization rates and
increasing day rates has significantly improved the Company's financial
performance since the third quarter of 1996 despite increased drilling operating
costs, including wages and benefits, and debt service over the same period.
Although the Company generated $10.2 million in net income during 1997, prior to
that the Company had not had a profitable full year since 1991.

FINANCIAL CONDITION AND LIQUIDITY

The significant changes in the Company's financial position from
December 31, 1996 to December 31, 1997 are primarily due to the Justiss and
Flournoy Acquisitions, the Kaiser-Francis Rig Purchase, the GWDC Acquisition,
the issuance of the Senior Notes and a common stock offering.

The following table summarizes the Company's financial position at
December 31, 1997 and 1996.

-------- ----- -------- -----
Total $482,715 100 $ 95,803 100
======== ===== ======== =====



The $320.6 million increase in net property and equipment, is a direct
result of the Company's acquisition and refurbishment programs. During 1997, the
Company acquired 56 additional drilling rigs and refurbished 23 from inventory.
These increases in property and equipment due to acquisitions and refurbishments
were partially offset by the sale of Indrillers and additional depreciation. In
connection with certain of these transactions, the Company recorded
approximately $45 million in deferred taxes due to the difference between the
purchase price and the tax basis of the assets acquired.

These acquisitions also accounted for approximately $78.7 million of
the $184.6 million increase in shareholders' equity as 12.4 million shares were
issued in the Flournoy Acquisition and 14.0 million shares were issued in the
GWDC Acquisition. The remaining increase in shareholders' equity is due to net
income of $10.2 million and the closing in November of a common stock offering.

On November 3, 1997, the Company closed an offering of 25.0 million
shares of its common stock. The Company sold 12.5 million newly issued common
shares and certain shareholders sold 12.5 million shares at $8.00 per share. The
Company received proceeds, net of underwriting discount, of approximately $95
million.

Working capital also increased by $60.4 million from December 31, 1996
to December 31, 1997. This is primarily due to an increase in cash and cash
equivalents of $47.5 million. This increase was primarily a result of $239.0
million provided by financing activities and $21.8 million provided by operating
activities partially offset by $213.3 million used in investing activities.

OPERATING ACTIVITIES

During the year ended December 31, 1997, $21.8 million was provided by
operating activities. This was a result of $37.1 million in cash generated from
operations offset by changes in working capital items of $15.3 million. Cash
used for working capital items consisted primarily of an increase in accounts
receivable of $28.3 million partially offset by an increase in accounts payable.

The increased working capital requirements were a result of certain of
the acquisitions completed by the Company. Acquisitions of drilling rigs and
certain other related equipment require additional working capital to operate.


-18-

19



INVESTING ACTIVITIES

During 1997, the Company invested $213.3 million in property and
equipment, net of asset sales. The cash portion of the purchase price for the
GWDC Acquisition, including transaction costs, accounted for $62.0 million and
the cash acquisition of Justiss, the Kaiser-Francis rigs and the other rig
purchase accounted for $79.7 million. In addition, during 1997 the Company spent
$52.1 million on rig refurbishments and $19.5 million on drill pipe and other
drilling related equipment. In addition, the acquisitions of Flournoy and GWDC
resulted in $40.5 million and $86.0 million, respectively, in non-cash additions
to property and equipment.

FINANCING ACTIVITIES

During 1997, the Company obtained a net $239.0 million from financing
activities, consisting principally of net proceeds of $169.1 million from the
issuance of Senior Notes, net proceeds from the issuance of common stock of
$94.3 million and borrowings and repayments under the Bank Credit Facility.
These borrowings were used to fund the cash portion of the GWDC acquisition and
the Justiss, Kaiser-Francis and other rig purchases, as well as to fund working
capital requirements and capital expenditures discussed above. The Company had
cash and cash equivalents of $53.6 million at December 31, 1997.

RECENT ACQUISITION

On January 30, 1998, the Company acquired all of the outstanding common
stock of Murco Drilling Corporation ("Murco") for $59.6 million in cash. The
Company funded this stock purchase out of working capital and $28.0 million in
borrowings under its bank credit facility.

FUTURE ACTIVITIES

The Company anticipates substantial funding requirements with its rig
refurbishment program during 1998. The Company currently has three rigs under
refurbishment and will begin refurbishment of the remaining 12 as demand
warrants. The Company estimates total costs for pending and planned
refurbishment will total approximately $37.5 million. These estimates are based
on deployment of all 15 rigs to the Company's four core domestic markets at an
estimated average refurbishment cost of $2.5 million per rig, including the cost
of a new drill string. If the Company instead chooses to refurbish rigs for
service in the Venezuelan or other international markets, it is estimated that
the average refurbishment cost of such rigs will be $12.0 million per rig,
including the cost of a new drill string. Overall estimated capital expenditures
for rig refurbishments would be correspondingly increased by the incremental
refurbishment cost of rigs destined for international markets.

The Company believes that the cash flow from operations, and to the
extent required, further borrowings under the Bank Credit Facility or other
external debt financing, will be sufficient to fund the Company's refurbishment
program and meet its other anticipated capital expenditures for 1998.

The Company continues to actively review possible acquisition
opportunities. While the Company has no agreements to acquire additional
businesses or equipment other than the Murco Acquisition completed in 1998,
suitable opportunities may arise in the future. The timing or success of any
acquisition effort and the size of the associated potential capital commitments
cannot be predicted at this time. The ability of the Company to consummate any
such transaction will be dependent in large part on its ability to fund such
transactions. There can be no assurance that adequate funding will be available
on terms satisfactory to the Company.

CERTAIN CREDIT ARRANGEMENTS

The Company's principal credit arrangements (other than customary trade
credit and capital leases) consist of a bank credit facility and its recently
issued Senior Notes.

Bank Credit Facility. The Company has a senior secured revolving credit
facility from three commercial banks under which the Company and its principal
domestic subsidiary, Grey Wolf Drilling Company (formerly Drillers, Inc.) are
co-borrowers (the "Bank Credit Facility"). The Bank Credit Facility provides the
borrower with the ability to borrow up to $50.0 million from time to time prior
to April 30, 2000, subject to the reductions described below, with up to $5.0
million of such amount available for letters of credit. Interest under the Bank
Credit Facility accrues at a

-19-

20



variable rate, using (at the borrowers' election) either the agent bank's base
rate plus a margin ranging from 0.75% to 1.50%, depending upon the Company's
debt to EBITDA ratio for the trailing 12 month period, or a rate based on the
interbank Eurodollar market plus a margin ranging from 1.75% to 2.50%, depending
upon the Company's debt to EBITDA ratio for the trailing 12 month period.
Letters of credit accrue a fee of 0.25% per annum. The borrowers pay a
commitment fee of 0.5% per annum on the average unused portion of the lenders'
commitments. Indebtedness under the Bank Credit Facility is secured by a
security interest in substantially all of the Company's and its domestic
subsidiaries assets and by guarantees of certain of its wholly-owned
subsidiaries.

The lenders' commitments will be reduced by the amount of net cash
proceeds received by the Company or its subsidiaries from sales of collateral in
excess of $1.0 million individually or $2.0 million in the aggregate in any
twelve month period. In addition, mandatory prepayments would be required upon
(i) the receipt of net proceeds received by the Company or its subsidiaries from
the incurrence of certain other debt or sales of debt or equity securities in a
public offering or private placement, or (ii) the receipt of net cash proceeds
by the Company or its subsidiaries from asset sales (including proceeds from
sale of rigs identified in the credit agreement as equipment held for sales but
excluding proceeds from dispositions of inventory in the ordinary course of
business, certain licenses of intellectual property and certain inter-company
transfers) or the receipt of insurance proceeds on assets of the borrowers, in
each case in this clause (ii) to the extent that such proceeds are in excess of
$500,000 individually or $1.0 million in the aggregate in any twelve month
period. The final maturity date of the Bank Credit Facility is April 30, 2000.

Among the various covenants that must be satisfied by the Company under
the Bank Credit Facility are the following five financial covenants pursuant to
which the Company may not permit: (i) working capital (as defined in the Bank
Credit Facility) to be less than $5.0 million on the last day of any fiscal
quarter; (ii) consolidated net worth to be less than the sum of $60 million plus
(a) 50% of the Company's consolidated net income, if positive, for the period
from January 1, 1997, to the final day of the most recent period for which
consolidated financial information of the Company is available and (b) 50% of
the increase to shareholders' equity of the Company attributable to the issuance
of common stock; (iii) the ratio of (a) the appraised fair market value of
domestic rigs and related equipment to (b) the lenders' commitments to be less
than 2 to 1; (iv) the ratio of consolidated debt to total capitalization to
exceed 0.6 to 1 and (v) the ratio of consolidated EBITDA to consolidated
interest expense for the most recent quarter to be less than 2.5 to 1 through
December 31, 1997 and less than 3 to 1 thereafter.

The Bank Credit Facility also contains provisions restricting the
ability of the Company and its subsidiaries to, among other things, (i) engage
in new lines of business unrelated to their current activities, (ii) enter into
mergers or consolidations or asset sales or purchases (with specified
exceptions), (iii) incur liens or debts or make advances, investments or loans
(in each case, with specified exceptions), (iv) pay dividends or redeem stock
(except for certain inter-company transfers), (v) prepay or materially amend any
other indebtedness and (vi) issue any stock (other than common stock).

Events of default under the Bank Credit Facility include, in addition
to non-payment of amounts due, misrepresentation and breach of loan covenants
and certain other events of default, (i) default with respect to other
indebtedness in excess of $350,000, (ii) judgments in excess of $350,000 and
(iii) a change of control (meaning that (a) the Company ceases to own 100% of
its two principal subsidiaries, (b) some person or group (other than persons
name in clause (d) below) has either acquired beneficial ownership of 30% or
more of the Company or obtained the power to elect a majority of the Company's
board of directors, (c) the Company's board of directors ceases to consist of a
majority of "continuing directors" (as defined in the Bank Credit Facility) or
(d) Norex Drilling Ltd., Somerset Drilling Associates, L.L.C. ("SDA") and
Somerset Capital Partners ("SCP") cease to own or control at least 25% of the
Company.

Senior Notes. Concurrently with the closing of the GWDC Acquisition,
the Company concluded a public offering of $175 million in principal amount of
the Senior Notes. The net proceeds from the sale of the Senior Notes were used
(i) to pay the cash portion of the GWDC Acquisition price, (ii) to repay the
Company's then outstanding balance under its revolving line of credit from its
commercial banks, (iii) to pay the purchase price for the Kaiser-Francis Rig
Purchase and the Additional Rig Purchases and (iv) for capital expenditures to
refurbish certain of the Company's rigs and for other general corporate
purposes. The Senior Notes are general unsecured senior obligations of the
Company and are guaranteed, on a joint and several basis, by all domestic
wholly-owned subsidiaries of the Company.

The Senior Notes will be redeemable, at the Company's option, in whole
or in part from time to time on or after July 1, 2002, at redemption prices
decreasing from 104.4375% in 2002 to 100% in 2005 and thereafter, plus accrued


-20-

21



and unpaid interest to the redemption date. In the event the Company consummates
one or more Qualified Equity Offerings (as defined in the Indenture) on or prior
to July 1, 2000, the Company at its option may use all or a portion of the net
cash proceeds form such Qualified Equity Offerings to redeem up to 30% of the
aggregate principal amount of the Senior Notes at a redemption price equal to
108.875% of the aggregate principal amount thereof, together with accrued and
unpaid interest to the date of redemption, provided that at least $120 million
aggregate principal amount of Senior Notes remains outstanding immediately after
such redemption. Although the Company's recent equity offering qualified as a
Qualified Equity Offering, the Company did not use the proceeds of the offering
to repay any portion of the Senior Notes. Upon a Change of Control as defined in
the Indenture, each holder of Senior Notes will have the right to require the
Company to repurchase all or any part of such holder's Senior Notes at a
purchase price equal to 101% of the aggregate principal amount thereof, plus
accrued and unpaid interest to the date of purchase.

The Indenture permits the Company and its subsidiaries to incur
additional indebtedness, including senior indebtedness of up to $100.0 million
aggregate principal amount which may be secured by liens on all of the assets of
the Company and its subsidiaries, subject to certain limitations. The Indenture
contains other covenants limiting the ability of the Company and its
subsidiaries to, among other things, pay dividends or make certain other
restricted payments, make certain investments, incur additional indebtedness,
permit liens, incur dividend and other payment restrictions affecting
subsidiaries, enter into consolidation, merger, conveyance, lease or transfer
transactions, make asset sales, enter into transactions with affiliates or
engage in unrelated lines of business. These covenants are subject to certain
exceptions and qualifications.

OTHER

The Company has not paid any cash dividends on the Company's common
stock and does not anticipate paying dividends on the Company's common stock at
any time in the foreseeable future. Furthermore, the Bank Credit Facility
prohibits the payment of dividends without the consent of the participating
banks.

COMPARISON OF FISCAL YEAR ENDED DECEMBER 31, 1997 AND 1996

Contract drilling revenues increased approximately $134.1 million, or
163.9%, to $215.9 million for the year ended December 31, 1997 compared to $81.8
million for the year ended December 31, 1996. This increase is primarily due to
an increase in revenue from domestic operations of $156.9 million due to an
increase in average revenue per day of $1,437 and an increase in utilization of
16,525 days. The increase in operating days is due to the acquisition of 57
operating rigs in late 1996 and 1997 as well as an overall increase in
utilization. The increase in revenue from domestic operations was partially
offset by a decrease in revenue from foreign operations of $22.8 million where
rig days worked decreased by 2,864 days. During 1996 the Company suspended its
operations in the Mexico and Argentina markets due to a decline in revenue per
day and rig utilization. Revenue generated in Mexico and Argentina markets
during 1997 was zero compared to $11.3 million for the year ended December 31,
1996. Revenue generated in Venezuela decreased by $11.5 million to $6.5 million
for the year ended December 31, 1997 compared to $18.0 million for the year
ended December 31, 1996. This decrease is due primarily to the expiration of a
contract to supply labor for four drilling rigs.

Drilling expenses increased by $82.2 million, or 102.2%, to $162.6
million for the year ended December 31, 1997 compared to $80.4 million for the
year ended December 31, 1996. The increase is due to an increase in drilling
expenses from domestic operations of $105.4 million partially offset by a
decrease in drilling expenses from foreign operations of $23.2 million. Drilling
expenses from domestic operations increased by $105.4 million, or 213.4%, to
$154.8 million for the year ended December 31, 1997 from $49.4 million for the
year ended December 31, 1996. This increase is primarily due to increased
utilization but is also partially due to increasing direct labor and other
costs. The decrease in drilling expenses from foreign operations of $23.2
million, or 74.8%, to $7.7 million for the year ended December 31, 1997 from $
31.0 million for the year ended December 31, 1996 is due to the withdrawal from
the Mexico and Argentina markets and the expiration of the labor contracts in
Venezuela discussed previously.

Depreciation expense increased by $16.3 million, or 346.8%, to $21.0
million for the year ended December 31, 1997 compared to $4.7 million for the
year ended December 31, 1996. However, depreciation as a percentage of revenue
increased by only 4% to approximately 10% for the year ended December 31, 1997
from 6% for the year ended December 31, 1996. The increase is due to the
incrementally higher cost basis of the rigs acquired in recent transactions.

During the year ended December 31, 1996 the company recorded
non-recurring charges of $6.1 million which included $1.1 million in employment
severance costs, $4.6 million dollars in cost to exit the Argentina and Mexico
markets and $400,000 of other non-recurring charges. The employment severance
cost included $602,000 in contractual severance pay to be paid over a two year
period to the Company's former President and Chief Executive Officer and the
transfer to him of certain drilling equipment with a net book value of $535,000
in settlement of a dispute over stock options to purchase Company common stock.
As a result of the Company's desire to redeploy assets to more productive
markets the Company has withdrawn from both the Argentina and Mexico markets. As
a result, in 1996, the Company recorded estimated exit cost of $1.3 million for
Mexico which primarily consisted of the forfeiture of a performance bond and
other costs incurred to close the office and exit cost of $800,0000 for
Argentina which primarily consist of costs incurred during the period necessary
to exit the market and close the office. In addition, during the first quarter
of 1997, the Company sold three of the six drilling rigs and certain other
assets located in Argentina for $1.5 million. In contemplation of the sale, in
1996 the Company recorded a write down of rig equipment and other assets of $2.5
million. The remaining Argentina drilling rigs have been mobilized out of
Argentina to the United States where they have been refurbished and returned to
service. Mobilization costs of approximately $900,000 were incurred during 1997
and are included in operating expense.

General and administrative expenses increased by $3.8 million, or
88.4%, to $8.1 million for the year ended December 31, 1997 compared to $4.3
million for the year ended December 31, 1996 due to increased payroll cost of
new management members and increased staff size. General and administrative
expenses as a percentage of revenue, however, have decreased to 3.7% for the
year ended December 31, 1997 from 5.2% for the year ended December 31, 1996.

Interest expense increased by $7.5 million, or 625%, to $8.7 million
for the year ended December 31, 1997 compared to $1.2 million for the year ended
December 31, 1996. This is primarily due to the issuance of $175 million in
Senior Notes during June 1997 to complete the Grey Wolf Acquisition and continue
the refurbishment of the rigs purchased in the stacked rig acquisitions.

COMPARISON OF FISCAL YEAR ENDED DECEMBER 31, 1996 AND 1995

Revenues decreased approximately $12.9 million, or 13.6%, to $81.8
million for the year ended December 31, 1996 from $94.7 million for the year
ended December 31, 1995. This decrease was primarily due to a decrease in
revenues from foreign operations of $20.6 million where rig utilization
decreased by 1,711 days. Revenues generated in the Mexican and Argentine markets
decreased by $17.3 million to $11.3 million for the year ended December 31,
1996, compared to $28.6 million for the year ended December 31, 1995, due to a
decline in average revenues per day, lower rig utilization and the Company's
ultimate withdrawal from these markets. Revenues generated in Venezuela
increased slightly to $18.0 million for the year ended December 31, 1996 from
$17.1 million for the year ended December 31, 1995. The increase was due to
increases in day rates received because the number of rig days worked decreased
by 360 days caused by the non-renewal of several drilling contracts for which
the Company was unable to obtain replacement contracts from the same or other
customers. The remainder of the decrease in revenues from foreign operations was
due to $4.2 million in non-recurring export sales during the year ended December
31, 1995. The decrease in revenues from foreign operations was partially offset
by a $7.7 million increase in revenues from domestic operations to $52.5 million
for the year ended December 31, 1996, as compared to $44.8 million for the year
ended December 31, 1995. Domestic rig utilization improved by 7.0% in 1996, and
average revenues per day increased by 5.0%, due to an overall improvement in the
domestic contract drilling market.

Drilling operating expenses decreased by $13.4 million, or 14.3%, to
$80.4 million for the year ended December 31, 1996, from $93.8 million for the
year ended December 31, 1995. The decrease was due to a $22.0 million decrease
in foreign drilling expenses, which was partially offset by an $8.6 million
increase in drilling expenses from domestic operations. Drilling expenses
associated with the Company's Mexican and Argentine operations decreased by
$16.0 million to $15.3 million for the year ended December 31, 1996 from $31.3
million for the year ended December 31, 1995. This decrease was due to lower
utilization in, and the Company's ultimate withdrawal from, those markets.
Drilling operating expenses included $1.0 million in mobilization costs to
transport the Company's drilling rigs from Mexico to the United States. Drilling
expenses in Venezuela decreased by $1.3 million to $15.7 million for the year
ended December 31, 1996 from $17.0 million for the year ended December 31, 1995
primarily because of lower rig utilization in 1996. Also contributing to the
decrease in operating expenses from foreign operations was $4.7 million in costs
related to non-recurring export sales for the year ended December 31, 1995.
Drilling expenses from domestic operations increased $8.6 million to $49.4
million for the year ended December 31, 1996, from $40.9 million for the year
ended December 31, 1995. This increase was primarily due to increased
utilization and, to a lesser extent, increased direct labor costs.

Depreciation and amortization expenses decreased by $143,000, or 3%, to
$4.7 million for the year ended December 31, 1996 from $4.8 million for the year
ended December 31, 1995. The decrease in depreciation expense was primarily
attributable to the decrease in the depreciable asset base resulting from the
$5.3 million impairment provision recorded in the fourth quarter of 1995 as a
result of the Company's adoption of SFAS No. 121, as described below. While the
RTO/LRAC Acquisition, which occurred in August 1996, increased the Company's
asset base, no depreciation expense will be recorded until the acquired rigs are
placed in service. Only one of these rigs was placed in service in late 1996.

During the year ended December 31, 1996, the Company recorded
non-recurring charges of $6.1 million which included $1.1 million in employment
severance costs, $4.6 million in costs to exit the Argentine and Mexican markets
and approximately $400,000 of other non-recurring charges. The employment
severance costs includes $602,000 in contractual severance pay to be paid over a
two-year period to the Company's former President and Chief Executive Officer
and the transfer to him of certain drilling equipment with a net book value of
$535,000 in settlement of a dispute over options to purchase common stock. As a
result of the Company's desire to redeploy assets to more productive markets,
the Company decided in late 1996 to withdraw from both the Argentine and Mexican
markets and has recorded estimated exit costs of $1.3 million for Mexico, which
primarily consist of the forfeiture of a performance bond and other costs to be
incurred to close the office, and exit costs of $800,000 for Argentina, which
primarily consist of costs expected to be incurred during the period necessary
to exit the market and close the office. Additionally, in 1996, the Company
agreed to sell three of the six drilling rigs and certain other assets located
in Argentina for $1.5 million. As a result, the Company recorded a write down of
rig equipment and other assets of $2.5 million. The remaining Argentine drilling
rigs have been returned to the United States where they have been or will be
refurbished and returned to service.

General and administrative expenses increased by $719,000 to $4.3
million for the year ended December 31, 1996, from $3.6 million for the year
ended December 31, 1995, due to increased payroll cost associated with the new
management members and the increased corporate staff, legal fees associated with
unsuccessful litigation to recover amounts the Company believed it was owed and
other professional fees.

Interest expense decreased by $252,000 for the year ended December 31,
1996, primarily as a result of lower average outstanding debt levels during 1996
in the United States and lower outstanding levels on an overdraft facility in
Argentina. The consolidated average debt balances during 1996 and 1995 were
$13.7 million and $15.0 million, respectively. Interest rates during these
periods remained relatively unchanged.

Other income, net increased $2.5 million to $4.1 million in 1996 from
$1.6 million in 1995 primarily as a result of a $2.8 million gain recorded in
connection with the sale of its Western Division in the second quarter of 1996.

INFLATION AND CHANGING PRICES

Contract drilling revenues do not necessarily track the changes in
general inflation as they tend to respond to the level of activity on the part
of the oil and gas industry in combination with the supply of equipment and the
number of competing companies. Capital and operating costs are influenced to a
larger extent by specific price changes in the oil and gas industry and to a
lesser extent by changes in general inflation.

FOREIGN EXCHANGE

Venezuelan operations are often performed by the Company pursuant to
drilling contracts under which payments to the Company are denominated in United
States Dollars but are payable in Venezuelan currency at a floating exchange
rate. Although the Company's Venezuelan contracts usually allow the Company to
exchange up to 35% of payments made to it in Venezuelan currency for United
States Dollars for a limited period of time following the payment and at the
official Venezuelan exchange rate in effect at the time the payment was made to
the Company (thus offering limited protection against adverse fluctuation), the
Company is typically subject to the risk of adverse currency fluctuations with
respect to the balance of such payments. Additionally, a significant portion of
costs and expenses relating to the Company's international operations are
comprised of goods and services procured in the respective foreign countries and
paid for in the respective countries' currencies. Accordingly, management
expects that the Company's subsidiaries operating in Venezuela will be required
to maintain significant cash balances in Venezuelan currency. The Company is not
a party to any currency hedging arrangements and has not during the three-year
period ending December 31, 1997 entered into any currency hedges to protect it
from foreign currency losses. Instead, the Company attempts to manage assets in
foreign countries to minimize its exposure to currency fluctuations. Despite
those efforts, however, the Company remains subject to the risk of foreign
currency losses. During the year ended December 31, 1995, the Company realized
currency gains of $888,000 and, in 1997 and 1996, $50,000 and $404,000,
respectively, were recorded as decreases in shareholders' equity due to a
devaluation of the Venezuelan Bolivar.

FORWARD-LOOKING INFORMATION

This Annual Report on Form 10-K contains "forward-looking statements"
within the meaning of Section 27A of the Securities Act of 1933, as amended, and
Section 21E of the Securities Exchange Act of 1934, as amended. All statements
other than statements of historical facts included in this report including,
without limitation, statements regarding the Company's business strategy, plans,
intentions, objectives and beliefs of management for future operations are
forward looking statements, including the Company's intentions with respect to
rig refurbishments and rig deployment. Although the Company believes the
expectations and beliefs reflected in such forward-looking statements are
reasonable, it can give no assurance that such expectations will prove to have
been correct. Important factors that could cause actual results to differ
materially from the Company's expectations ("Cautionary Statements") are
discussed in Item 1 "Business" and Item 7 "Management's Discussion and Analysis
of Financial Condition and Results of Operations."

YEAR 2000 COMPLIANCE

The Company expects that the cost of converting its computer systems to
year 2000 compliance will be between $100,000 and $200,000, which is not
material to its financial condition. The Company believes that it will be able
to achieve year 2000 compliance by the end of 1999, and it does not currently
anticipate any disruption in its operations


-25-

as a result of any failure by the Company to be in compliance. The Company does
not currently have any information concerning the year 2000 compliance status of
its customers or vendors.

ACCOUNTING MATTERS

In June 1997, the FASB issued Statement of Financial Accounting
Standards No. 130, Reporting Comprehensive Income ("SFAS 130"), which
establishes standards for reporting and display of comprehensive income and its
components. The components of comprehensive income refer to revenues, expenses,
gains and losses that are excluded from net income under current accounting
standards, including foreign currency translation items, minimum pension
liability adjustments and unrealized gains and losses on certain investments in
debt and equity securities. SFAS 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 other financial
statements; the total of other comprehensive income for a period is required to
be transferred to a component of equity that is separately displayed in a
statement of financial position at the end of an accounting period. SFAS 130 is
effective for both interim and annual periods beginning after December 15, 1997.
The Company will adopt SFAS 130 in the quarter ending March 31, 1998.

In June 1997, the FASB issued Statement of Financial Accounting
Standards No. 131, Disclosures about Segments of an Enterprise and Related
Information ("SFAS 131"). SFAS 131 establishes standards for the way public
enterprises are to report information about operating segments in annual
financial statements and requires the reporting of selected information about
operating segments in interim financial reports issued to stockholders. It also
establishes standards for related disclosures about products and services,
geographic areas and major customers. SFAS 131 is effective for periods
beginning after December 15, 1997. The Company will adopt SFAS 131 in the
quarter ending March 31, 1998.

GREY WOLF, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


(1) Summary of Significant Accounting Policies

Nature of Operations. Grey Wolf, Inc., (formerly DI Industries, Inc.)
is a Texas corporation formed in 1980. On July 14, 1997, by written consent, the
Board of Directors and certain shareholders of DI Industries, Inc. approved an
amendment to the corporate charter to change the name of the company from DI
Industries, Inc. to Grey Wolf, Inc. The Articles of Amendment effecting the
amendment were filed with the Texas Secretary of State on September 18, 1998.

Principles of Consolidation and Basis of Presentation. Grey Wolf, Inc.
is engaged in the business of providing onshore contract drilling services to
the oil and gas industry. Grey Wolf, Inc. and its subsidiaries conduct
operations in Texas, Arkansas, Louisiana, Mississippi and other states and
currently have international operations in Venezuela. The consolidated financial
statements include the accounts of Grey Wolf, Inc. and its majority-owned
subsidiaries ("the Company" or "Grey Wolf"). All significant intercompany
accounts and transactions are eliminated in consolidation.

Inventory. Inventory consists primarily of drilling and support
equipment and is stated at the lower of specifically identified cost or market.

Assets Held for Sale. Assets held for sale are primarily comprised of
drilling rigs and equipment and is stated at the Company's net book value.
Management believes the carrying value is less than net realizable value on the
basis of purchase offers received in 1997 and 1996 and recent appraisals.

Property and Equipment. Property and equipment is stated at cost.
Depreciation is provided using the straight-line method over the estimated
useful lives of the assets between three and twelve years. The Company's
producing oil and gas properties were sold on August 9, 1995. Such properties
were recorded using the full-cost method of accounting. Under this method, all
costs incurred in connection with the exploration for and development of oil and
gas were capitalized. Depreciation, depletion and amortization of oil and gas
properties was computed on the basis of physical units, with oil and gas
converted to a common unit of measure based on the approximate relative energy
content. Unamortized costs were compared to the present value of estimated
future net revenues and any excess was charged to expense during the period in
which the excess occurred.

In March 1995, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standard (SFAS) No. 121, "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of,"
effective for years beginning after December 15, 1995. As the FASB encouraged
earlier application, the Company adopted the provisions of SFAS No. 121 during
the fourth quarter of 1995. This accounting standard requires certain assets be
reviewed for impairment whenever events or circumstances indicate the carrying
amount may not be recoverable. During 1995, the Company provided a provision of
$5.3 million for certain drilling rigs and equipment due to market indications
that the carrying amounts were not fully recoverable. Net realizable value was
determined based upon appraisal, comparable sale data and management estimates.

Revenue Recognition. Revenue from turnkey drilling contracts is
recognized using the percentage-of-completion method based upon costs incurred
to date and estimated total contract costs. Revenue from daywork, footage and
hourly drilling contracts is recognized based upon the provisions of the
contract. Provision is made currently for anticipated losses, if any, on
uncompleted contracts.

Foreign Currency Translation. Assets and liabilities of foreign
subsidiaries have been translated into United States dollars at the applicable
rate of exchange in effect at the end of the period reported. Revenues and
expenses have been translated at the applicable weighted average rates of
exchange in effect during the period reported. Translation adjustments are
reflected as a separate component of shareholders' equity. Any transaction gains
and losses are included in net income. During 1997 and 1996 respectively, the
Company recorded unrealized translation losses of $50,000 and $404,000 as a
reduction of shareholders' equity. During the year ended December 31, 1995, the
Company realized currency gains of $888,000.

Income (Loss) per Share. In February 1997 the Financial Accounting
Standards Board (FASB) issued Statement of Financial Accounting Standards No.
128 ("SFAS 128"), Earnings per Share. SFAS No. 128 specifies new


-35-

36


GREY WOLF, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


measurement, presentation and disclosure requirements for earnings per share and
is required to be applied retroactively upon initial adoption. The Company has
adopted SFAS No. 128 effective with the release of December 31, 1997 earnings
data, and accordingly, has restated herein all previously reported earnings per
share data. Basic earnings per share is based on weighted average shares
outstanding without any dilutive effects considered. Diluted earnings per share
reflects dilution from all contingently issuable shares, including options,
warrants and convertible preferred stock. A reconciliation of the weighted
average common shares outstanding on a basic and diluted basis is as follows:




1997 1996 1995
-------- -------- --------

Weighed average common shares
outstanding - Basic 145,854 67,495 38,669

Effect of dilutive securities:
Options 2,883 -- --
Redeemable preferred stock 329 -- --
Warrants 658 -- --
-------- -------- --------
3,870 -- --
Weighted average common shares
outstanding - Diluted 149,724 67,495 38,669
======== ======== ========



Income Taxes. The Company utilizes the asset and liability method in
accounting for income taxes that requires recognition of deferred income tax
liabilities and assets for the expected future tax consequences of events that
have been recognized in the Company's financial statements or tax returns. Under
this method, deferred income tax liabilities and assets are determined based on
the temporary differences between the financial statement carrying amounts and
the tax bases of existing assets and liabilities and available tax credit
carryforwards. The effect on deferred tax assets and liabilities of a change in
tax rates is recognized in income in the period that includes the enactment
date.

Interest Capitalization. Interest is capitalized on rig refurbishments
during the refurbishment period. Interest is capitalized to the rigs using an
allocation method based on the Company's actual interest cost. Total interest
capitalized for the year ended December 31, 1997 was $1.8 million. No interest
was capitalized for the years ended December 31, 1996 or 1995.

Fair Value of Financial Instruments. The carrying amount of the
Company's cash and short-term investments approximates fair value because of the
short maturity of those instruments. The carrying amount of the Company's
reducing revolving line of credit approximates fair value as the interest is
indexed to the prime rate or LIBOR. The carrying amount of the Company's Senior
Notes approximates fair value as interest rates have not changed significantly
since the notes were issued on June 27, 1997.

Cash Flow Information. Cash flow statements are prepared using the
indirect method. The Company considers all unrestricted highly liquid
investments with a maturity of three months or less at the time of purchase to
be cash equivalents.

Restricted Cash. Restricted cash consists of investments in interest
bearing certificates of deposit totaling $450,000 and $1.0 million at December
31, 1997 and 1996, respectively as collateral for a letter of credit securing
insurance deposits. The carrying value of the investments approximates the
current market value.

Use of Estimates. The preparation of financial statements in conformity
with generally accepted accounting principles requires the use of certain
estimates and assumptions relating to the reporting of assets and liabilities
and the disclosure of contingent assets and liabilities. Actual results could
differ from those estimates.

Concentrations of Credit Risk. Substantially all of the Company's
contract drilling activities are conducted with independent oil and gas
companies in the United States or with national petroleum companies in South
America. Historically, the Company has not required collateral or other security
for the related receivables from such customers. However, the Company has
required certain customers to deposit funds in escrow prior to the commencement
of drilling. Actions typically taken by the Company in the event of nonpayment
include filing a lien on the customer's producing properties and filing suit
against the customer.

GREY WOLF, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


Other recent accounting pronouncements. In June 1997, the FASB issued
Statement of Financial Accounting Standards No. 130, Reporting Comprehensive
Income ("SFAS 130"), which establishes standards for reporting and display of
comprehensive income and its components. The components of comprehensive income
refer to revenues, expenses, gains and losses that are excluded from net income
under current accounting standards, including foreign currency translation
items, minimum pension liability adjustments and unrealized gains and losses on
certain investments in debt and equity securities. SFAS 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 other financial statements; the total of other comprehensive
income for a period is required to be transferred to a component of equity that
is separately displayed in a statement of financial position at the end of an
accounting period. SFAS 130 is effective for both interim and annual periods
beginning after December 15, 1997. The Company will adopt SFAS 130 in the
quarter ending March 31, 1998.

In June 1997, the FASB issued Statement of Financial Accounting
Standards No. 131, Disclosures about Segments of an Enterprise and Related
Information ("SFAS 131"). SFAS 131 establishes standards for the way public
enterprises are to report information about operating segments in annual
financial statements and requires the reporting of selected information about
operating segments in interim financial reports issued to stockholders. It also
establishes standards for related disclosures about products and services,
geographic areas, and major customers. SFAS 131 is effective for periods
beginning after December 15, 1997. The Company will adopt SFAS 131 in the
quarter ending March 31, 1998.

(2) SIGNIFICANT PROPERTY TRANSACTIONS

On May 7, 1996 the Company entered into two separate definitive merger
agreements (the "Mergers") to effect a $25 million equity infusion and the
acquisition of deep drilling equipment. These Mergers were closed on August 29,
1996.

Under the first agreement, R.T. Oliver, Inc. ("RTO") and Land Rig
Acquisition Corporation ("LRAC") merged with a new subsidiary of the Company
with the capital stock of RTO and LRAC being exchanged for 39,423,978 shares of
the Company's common stock. In addition, warrants were issued to acquire up to
1,720,000 additional shares of Grey Wolf common stock, the exercise of which is
contingent upon the occurrence of certain events. As a result of certain events
which occurred prior to year end, at December 31, 1997, 244,800 warrants
remained outstanding and the remainder were canceled. These Mergers resulted in
the acquisition of 18 inactive, deep capacity land drilling rigs which included
five 3,000 horsepower and nine 2,000 horsepower land rigs which are rated for
depths of 25,000 feet or greater. The Company placed nine of these rigs in
operation during 1997 and one of these rigs in operation during 1996.

Under the second agreement, a subsidiary of Somerset Drilling
Associates, L.L.C. ("Somerset"), a privately-held investment limited liability
company, was merged into the Company. The stock of the subsidiary was exchanged
for 39,423,978 shares of Grey Wolf common stock and warrants to acquire up to
1,720,000 shares of Grey Wolf common stock, the exercise of which is contingent
upon the occurrence of certain events. As a result of certain events which
occurred prior to year end, at December 31, 1997, 244,800 warrants remained
outstanding and the remainder were canceled. This merger transaction resulted in
a $25 million equity infusion into the Company.

A definitive proxy statement was mailed to shareholders of record as of
July 15, 1996, and the Mergers were approved by the shareholders at a meeting on
August 27, 1996. These Mergers resulted in an ownership change in the Company as
defined by Section 382 of the Internal Revenue Code which limits the ultimate
utilization of the Company's net operating loss carryforward (see footnote 3).

As part of the Merger agreements, the 1995 subscription by Norex
Drilling for 4,000 shares of Series B Preferred Stock and related Series B
Warrants was rescinded. The $4.0 million subscription plus accrued dividends
were repaid to Norex Drilling by the Company with the proceeds from a term loan
that was paid in full on December 30, 1996 from the proceeds of a private
placement of the Company's common stock (see below). Interest was at 12% and was
payable on the last business day of each calendar quarter.

GREY WOLF, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


On June 24, 1996, the Company closed a transaction whereby it sold all
of the operational assets of Western Oil Well Service Co. ("Western"), a
wholly-owned subsidiary of the Company, for $3.95 million in cash. Western
provided oil and gas well workover services principally in Montana, Utah and
North Dakota. Pursuant to the sale, the buyer assumed all of Western's existing
leases, primarily for vehicles, which totaled $251,000 at closing. The Company
recorded a gain of $2.8 million in the second quarter of 1996 as a result of
this sale.

On October 3, 1996 the Company acquired all of the South Texas
operating assets of Mesa Drilling, Inc. ("Mesa") in exchange for 5,500,000
shares of the Company's common stock. The assets acquired consisted of six
diesel electric SCR drilling rigs, three of which were operating in South Texas
and the other rigs were stacked. One of the stacked rigs was refurbished and
placed in service during 1997.

On December 31, 1996, the Company completed the acquisition of all the
South Texas operating assets of Diamond M Onshore, Inc., a wholly owned
subsidiary of Diamond Offshore Drilling, Inc. The assets were acquired for
approximately $26 million in cash and consist of ten land drilling rigs, all of
which are currently operating, 19 hauling trucks, a yard facility in Alice,
Texas and various other equipment and drill pipe. Grey Wolf hired the majority
of the personnel operating the assets.

On January 31, 1997, the Company acquired the operating assets of
Flournoy Drilling Company ("Flournoy") for 12.4 million shares of the Company's
common stock and $800,000 in cash. The assets acquired included 13 drilling
rigs, 17 rig hauling trucks, a yard and office facility in Alice, Texas, and
various other equipment and drill pipe. The Company agreed to issue additional
shares of common stock to Flournoy's shareholders if, and to the extent that on
January 31, 1998, the aggregate market value of one-half of the shares received
by the Flournoy shareholders less any shares sold, plus the gross proceeds from
certain sales of common stock received in the transaction by the Flournoy
shareholders prior to January 31, 1998, is, in total, less than $12.4 million.
No additional shares were required to be issued.

In May 1997, the Company increased its inventory of rigs held for
refurbishment by purchasing three rigs in three separate transactions for an
aggregate purchase price of $6.9 million in cash. One of the rigs was purchased
from an affiliate of one of the Company's directors. The Company refurbished two
of the three rigs and placed them in service during 1997.

In June 1997, the Company purchased three additional rigs to add to its
inventory of rigs to be refurbished for $8.9 million. These rigs were also
purchased from an affiliate of one of the Company's directors.

On June 27, 1997, the Company acquired all of the outstanding capital
stock of Grey Wolf Drilling Company ("GWDC") by merger in exchange for $61.6
million cash and 14.0 million shares of the Company's common stock. Transaction
costs of approximately $0.6 million were incurred in connection with the merger.
GWDC operated 18 large premium drilling rigs in South Louisiana and along the
upper Texas Gulf Coast. The merger was accounted for using purchase accounting
and as such, all revenues and expenses were recorded by the Company beginning
from the date of acquisition.

In July 1997, the Company purchased one operating rig for $2.4 million
in cash. In August 1997, the Company purchased six idle drilling rigs and
related equipment from Cactus Drilling Company, a division of Kaiser-Francis Oil
Company, for $25.4 million (the "Kaiser-Francis Rig Purchase"). Two of these
rigs have been refurbished and placed in service during 1997. The remaining rigs
will be refurbished and placed in service in the future as warranted by demand.

On September 15, 1997, the Company entered into a definitive agreement
to acquire substantially all of the operating assets of Justiss Drilling Company
(the "Justiss Acquisition"), a division of Justiss Oil Company, Inc. The assets
included a fleet of 12 operating drilling rigs and related equipment which are
currently operating in the Company's Ark-La-Tex and Gulf Coast markets. The
total purchase price for the Justiss acquisition was $36.1 million in cash of
which $28.6 million was paid on October 21, 1997, upon delivery of nine of the
12 rigs. The remaining three rigs were purchased and the balance of the purchase
price ($7.5 million) was paid in November 1997, as each rig

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


completed a turnkey drilling contract. The Company borrowed $28.0 million under
its bank credit facility for the first nine rigs and the November purchases were
funded from the Company's stock offering (discussed below).

On November 3, 1997, the Company closed an offering of 25.0 million
shares of the Company's common stock (the "Offering"). The Company sold 12.5
million newly issued common shares and certain selling shareholders sold 12.5
million additional shares at $8.00 per share. The Company received proceeds net
of underwriting discounts, of approximately $95.0 million. The expenses of the
offering were approximately $0.7 million. The proceeds of the Offering were used
to pay down the bank credit facility and to complete the Murco acquisition
discussed below.

On November 13, 1997, the Company closed the sale of its 65% interest
in INDRILLERS, L.L.C. ("Indrillers") and certain related drilling assets to Dart
Energy Corporation ("Dart") in exchange for $1.65 million in cash and title to a
1,200 horsepower SCR rig previously held by Indrillers. Indrillers, a limited
liability company, operated ten drilling rigs in Michigan and was formed in 1996
though the combination of certain drilling assets of the Company and Dart with
resulting ownership of 65% and 35%, respectively. Indrillers' rig fleet
consisted of nine smaller mechanical rigs ranging from 300 to 900 horsepower and
one 1,200 horsepower SCR rig. The Company recorded a gain of approximately
$700,000 on the sale.

On January 30, 1998, the Company acquired all of the outstanding common
stock of Murco Drilling Corporation ("Murco") for $59.6 million in cash. At
closing, Murco had net liabilities of approximately $5.4 million. The
consideration is subject to a final accounting adjustment for the actual net
liabilities of Murco. The Company funded this stock purchase out of working
capital and borrowing under its bank credit facility.

On February 26, 1998, the Company signed a definitive agreement to sell
all of the rigs and drilling related equipment of the Company's Eastern division
located in Ohio to Union Drilling, Inc. ("Union"), an affiliate of two of the
Company's directors, for $2.4 million. The sale closed in steps as each of the
rigs completed its current drilling contract with the last transaction being
completed on March 4, 1998. The Eastern division rig fleet consisted of six 450
horsepower mechanical rigs. The Company will recognize a gain on the sale during
the first quarter of 1998.

The December 31, 1997 consolidated balance sheet includes the effect of
the Flournoy acquisition, the GWDC Acquisition, the issuance of the Notes
(defined herein), the May, June, July and Kaiser-Francis stacked rig purchases
and the Company's common stock offering. The following unaudited pro forma
balance sheet assumes the Murco Acquisition occurred on December 31, 1997. The
following unaudited pro forma consolidated financial data for the year ended
December 31, 1997, includes the historical results of the Company for the year
ended December 31, 1997, and gives effect to the Murco Acquisition, the Flournoy
Acquisition, the GWDC merger, the Justiss Acquisition and issuance of the Notes
as if they occurred on January 1, 1996. The following unaudited pro forma
consolidated financial data for the year ended December 31, 1996, includes the
historical results of the Company for the year ended December 31, 1996, and
gives effect to each of the above transactions as well as the previously
disclosed merger, acquisition and sale transactions which occurred before
December 31, 1996, as if they occurred on January 1, 1996. The May, June, July
and Kaiser-Francis rig purchases have no historical operations as the rigs have
been stacked and the impact on the unaudited pro forma consolidated financial
data is not material and has not been presented.

Each of the Company's acquisitions have been accounted for using
purchase accounting. As such all revenues and expenses have been recorded by the
Company beginning at the date of acquisition.

(3) INCOME TAXES

The Company and its domestic subsidiaries file a consolidated U.S.
Federal income tax return. The Company's foreign owned subsidiaries file tax
returns in the country where they are domiciled. The Company records current
income taxes based upon its estimated tax liability in the United States and
foreign countries for the year. During 1997, the Company recorded $1,057,000 in
current U.S. income taxes and a reduction of $290,000 in current tax based on
its estimate of taxes payable in Venezuela. In 1996, the Company recorded
$845,000 of current tax expense based on its estimate of taxes payable in
Venezuela.

The Company follows Statement of Financial Accounting Standard No. 109
("SFAS No. 109") which requires the balance sheet approach of income tax
accounting whereby deferred income taxes are provided at the balance sheet date
for the (a) differences existing in the tax basis of assets and liabilities and
their financial statement carrying amounts plus (b) operating loss and tax
credit carryforwards.

At December 31, 1997 and 1996, the Company had U.S. net operating loss
("NOL") carryforwards of approximately $32.0 and $23.0 million, respectively and
investment tax credit ("ITC") carryforwards of approximately $2.4 million which
expire at various times through 2010 and 2000, respectively. The NOL and ITC
carryforwards are subject to annual limitations as a result of the changes in
ownership of the Company in 1989, 1994 and 1996.

For financial accounting purposes, approximately $21.0 million of the
NOL carryforwards was utilized to offset the book versus tax basis differential
in the recording of the assets acquired in the Mergers and the Mesa acquisition
in 1996.

Deferred tax liabilities of approximately $15.5 million exist at
December 31, 1997 and are comprised of temporary differences between federal
income tax and financial accounting practices for the Company's property and
equipment. Deferred tax benefits of $6.1 million exist at December 31, 1997,
attributable to costs that were expended for financial reporting purposes that
will be deducted in future years for income tax purposes. These items are
comprised of workmans compensation and bad debt reserves as well as net
operating loss carryforwards. These items are augmented by the $2.4 million of
investment tax credit carryforwards and $900,000 alternative minimum tax
carryforward. A valuation allowance of $2.4 million has been provided as the
Company believes it is more likely than not that the investment tax credits will
expire before they can be fully utilized by the Company.


-40-

41


GREY WOLF, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


At December 31, 1996, deferred tax liabilities and deferred tax assets
were $5.5 million and $3.7 million, respectively and investment tax
carryforwards were $2.4 million. A net deferred tax benefit of $600,000 was not
recognized in 1996 as a valuation allowance was provided against it, as the
recognition criteria set forth in SFAS No. 109 for a deferred tax asset, had not
been met.

In the Company's Venezuelan subsidiary, no temporary differences
existed as of December 31, 1997 or 1996. In the Company's other foreign
subsidiaries, the Company's net operating loss carryforwards and other timing
differences will not be recoverable since the Company has exited these markets.

The following summarizes the differences between the statutory tax
rates (35%, 34%, 34%, respectively) and the Company's effective tax rate
(amounts in thousands):

GREY WOLF, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS




On June 27, 1997, the Company issued $175.0 million of Senior Notes
(the "Notes") receiving gross proceeds of $174.1 million. The Notes bear
interest at 87/8% per annum payable semiannually and mature on July 1, 2007. The
Notes are general unsecured senior obligations of the Company and are guaranteed
by the Company's domestic subsidiaries. Proceeds from the Notes were used to
fund the cash portion of the GWDC Acquisition to repay the then outstanding
Facility balance of $47.0 million and to fund certain inventory rig purchases.
In connection with the issuance of the Notes, the Company paid approximately
$5.1 million in underwriting and financing costs which will be amortized over
the life of the Notes.

Except as discussed below, the Notes are not redeemable at the option
of the Company prior to July 1, 2002. On or after such date, the Company shall
have the option to redeem the Notes in whole or in part during the twelve months
beginning July 1, 2002 at 104.4375%, beginning July 1, 2003 at 102.9580%,
beginning July 1, 2004 at 101.479% and beginning July 1, 2005 and thereafter at
100.0000% together with any interest accrued and unpaid to the redemption date.

At any time during the first 36 months after the issue date, the
Company may at its option, redeem up to a maximum of 30% of the aggregate
principal amount with the net cash proceeds of one or more equity offerings at a
redemption price equal to 108.875% of the principal amount thereof, plus accrued
and unpaid interest thereon to the redemption date provided that at least $120.0
million aggregate principal amount shall remain outstanding immediately after
the occurrence of any such redemption.

On December 31, 1996, the Company closed a $35 million reducing
revolving line of credit ("the Facility") with a syndicate of commercial banks.
The Facility reduces by $5.0 million each year until the December 31, 1999
maturity date. On April 30, 1997, the Facility was amended and restated to
increase the line of credit to $50 million and to revise certain other terms and
covenants, including the elimination of mandatory $5.0 million reductions in the
line in January 1998 and 1999 and a conversion of the interest rate to a sliding
variable rate based on certain financial ratios of either LIBOR plus 1.75% to
2.5% or prime plus .75% to 1.5%. The Company pays commitment fees of .5% on the
unused portion of the Facility. The Facility is secured by substantially all the
Company's assets and calls for quarterly interest payments on the outstanding
balance. The Facility also contains customary affirmative and negative covenants
with which the Company was in compliance.

On August 28, 1996, the Company entered into a $4 million term loan
with Norex Drilling. The term loan was due on August 29, 1997, and bore interest
at 12%. The loan was paid in full from the proceeds of a private placement of
the Company's common stock on December 31, 1996.

During 1995, the Company issued 190,000 shares, out of 200,000
authorized, of Series A Preferred stock valued at $1,900,000. The Series A
Preferred is redeemable in cash at a redemption price payable from available
cumulative Venezuelan positive net cash flows, as defined, commencing the first
fiscal quarter following the original issuance date. The Company may redeem, at
any time, the Series A Preferred stock upon consent of the holders or upon
written notice commencing five years from the original issuance date. At the
election of the Company, dividends may be declared and payable in common stock
equivalent to the value of the dividends. Each Series A Preferred holder of
record has no voting right on any matters voted on by stockholders of the
Company. During March 1996, 100,000 shares of Series A Preferred, totaling
$1,000,000, were returned to the Company in settlement of asserted claims
against An-Son Drilling Company of Columbia, S.A. At December 31, 1995, the
balance of the Series A Preferred had been adjusted to reflect this settlement.
During 1997 and 1996, the Company voluntarily redeemed 45,900 and 13,500 shares,
respectively of Series A Preferred leaving 30,600 shares outstanding at December
31, 1997.

Annual maturities of the debt outstanding at December 31, 1997 for the
next five years are as follows: 1998 - $1,148,000; 1999 - $976,000; 2000 -
$708,000; 2001 - $359,000; and 2002 - $0.

(5) CAPITAL STOCK AND STOCK OPTION PLANS

During the fourth quarter of 1995, Norex Drilling subscribed to and
paid $4,000,000 for a new Company issue of Series B Preferred Stock (the "Series
B Preferred"), to be issued subsequent to December 31, 1995. This subscription
was in the form of 4,000 shares (10,000 authorized) of Series B 15% Senior
Cumulative Redeemable Preferred, par value $1. This stock had annual dividends
of 15% per annum, payable through the issuance of additional preferred shares
for the first three years. On August 28, 1996, the $4,000,000 subscription plus
accrued dividends was repaid to Norex Drilling by the Company with the proceeds
from a term loan.

In connection with closing the Facility, the Company completed a
private placement of 1,750,000 shares of Grey Wolf common stock for
approximately $4,120,000 to four funds managed by Wexford Management LLC. The
proceeds generated from this private placement were utilized to repay the above
mentioned $4,000,000 term note. Grey Wolf also agreed to issue more shares to
the extent the Wexford funds hold value less than $4,120,000 on the one-year
anniversary date of the issuance. Immediate shelf registration rights were also
granted by Grey Wolf in connection with the share issuance. These shares were
subsequently registered. No additional shares were required to be issued.

On November 3, 1997, the Company closed an offering of 25.0 million
shares of its common stock. The Company sold 12.5 newly issued common shares and
certain shareholders sold 12.5 million additional shares at $8.00 per share. The
Company received proceeds, net of underwriting discount, of approximately $95
million. Other costs incurred to complete the offering were approximately
$722,000 and were recorded as a reduction of additional paid-in capital.

The Company's 1982 Stock Option and Long-Term Incentive Plan for Key
Employees (the "1982 Plan") reserves 2,500,000 shares of the Company's common
stock for issuance upon the exercise of options. At December 31, 1997 options to
purchase 1,895,800 shares of common stock were available for grant under the
1982 Plan. The Company's 1987 Stock Option Plan for Non-Employee Directors (the
"1987 Director Plan") reserves 250,000 shares of common stock for issuance upon
the exercise of options and provides for the automatic grant of options to
purchase shares of common stock to any non-employee who becomes a director of
the Company. Options under the 1987 Director Plan to purchase 212,800 shares of
common stock were available for grant until June 30, 1997 when the plan was
canceled. The Company's 1996 Employee Stock Option Plan (the "1996 Plan")
reserves 7,000,000 shares of the Company's common stock for issuance upon the
exercise of options. At December 31, 1997 options under the 1996 Plan to
purchase 4,285,000 shares of common stock were available for grant until July
29, 2006. The exercise price of stock options under the 1982 Plan, the 1987
Director Plan and the 1996 Plan approximates the fair market value of the stock
at the time the option is granted. The Company has 2,360,000 shares reserved for
other Incentive Stock Option Agreements between the Company and its' executive
officers and directors. One million five hundred thousand of the shares are
reserved for the Company's President, and 500,000 are reserved for the Chairman
of the Board of Directors. The options become exercisable in varying increments
over four- to five-year periods and the majority of the options expire on the
tenth anniversary of the inception of the plans. The remaining shares are
reserved for non-employee directors and are immediately exercisable upon
issuance. Stock option activity for all plans was as follows (number of shares
in thousands):

At December 31, 1997, the Company has three stock-based compensation
plans, which are described above. The Company applies APB Opinion 25 and related
interpretations in accounting for its plans. Accordingly, no compensation cost
has been recognized. Had compensation cost for the Company's three stock-based
compensation plans been determined on the fair value at the grant dates for
awards under those plans consistent with the method of Statement of Financial
Accounting Standards ("SFAS") No. 123, the Company's net income and earnings per
share would have been reduced to the pro forma amounts indicated below (amounts
in thousands, except per share amounts):

Net income (loss)
As reported $ 10,218 $ (12,124) $ (13,447)

Earnings (loss) per share - basic and diluted
As reported $ .07 $ (.18) $ (.35)
Pro forma $ .06 $ (.20) $ (.35)



For purposes of determining compensation costs using the provisions of
SFAS No. 123, the fair value of option grants was determined using the
Black-Scholes option-valuation model. The key input variables used in valuing
the options were: risk-free interest rate based on the five-year Treasury strips
of 7.8%; dividend yield of zero; stock price volatility of 60%; and expected
option lives of five years.

(7) RELATED-PARTY TRANSACTIONS

Prior to June 2, 1994, certain of the Company's insurance coverage,
including workers' compensation and excess liability coverage, was arranged by
American Premier as part of a program which American Premier provided to its
subsidiaries. Subsequent to the sale of the Company's common shares by American
Premier, the Company obtained workers' compensation, excess liability coverage
and certain other insurance from other sources. The Company and American Premier
entered into an agreement pursuant to which the Company agreed to reimburse
American Premier for all amounts advanced by American Premier from time to time
on behalf of the Company in connection with American Premier's administration of
the Company's workers' compensation and certain other insurance programs for the
periods between July 20, 1989 and the closing of the common stock transaction.
The amount reimbursable to American Premier at December 31, 1995 relating to
this program was $1,900,000. All amounts outstanding under the program were paid
in full during 1996.

As part of the Merger agreements, the 1995 subscription by Norex
Drilling for 4,000 shares of Series B Preferred Stock and related Series B
Warrants was rescinded. The $4,000,000 subscription plus accrued dividends was
repaid to Norex Drilling by the Company with the proceeds from a term loan that
was made by Norex Drilling to the Company. Interest was at 12% and was payable
on the last business day of each calendar quarter. The note payable was paid in
full December 31, 1996 using the proceeds from a private placement of the
Company's common stock.

On June 10, 1996, Norex Drilling advanced $1,000,000 to the Company
pursuant to a Promissory Note (the "Note") and Commercial Security Agreement.
The Note provided for interest at 12% per annum and matured on the Closing Date
of the Merger transactions. The Company's domestic accounts receivable were
pledged under the security agreement. The Company repaid this loan, plus accrued
interest, in early July 1996 with the proceeds from the sale of the assets
discussed in footnote 2.

During 1996 a consulting fee of $10,000 per month was paid by the
Company under a consulting arrangement with the Company's Chairman of the Board.

One of the Company's directors is a partner in a law firm that
performed legal services for the Company. During 1997 and 1996 the Company paid
the firm $41,000 and $200,000, respectively.

As previously disclosed, during 1997 the Company purchased four
drilling rigs from an affiliate of one of the Company's directors.

As previously disclosed, the Company sold its Eastern Division assets
to Union, an affiliate of two of the Company's directors.

From time to time, in the normal course of business the Company
purchases equipment from an affiliate of one of the Company's directors.

(8) LEASE COMMITMENTS

Aggregate minimum lease payments required under noncancellable
operating leases having terms greater than one year are as follows as of
December 31, 1997: 1998 - $345,000; 1999 - $345,000; 2000 - $316,000; 2001 -
$265,000; and 2002 - $44,000.

Rent expense under operating leases for 1997, 1996 and 1995 was
approximately $268,000, $109,000 and $101,000, respectively.

Capital leases for the Company's field trucks and automobiles are
included in long-term debt.

(9) CONTINGENCIES

The Company is involved in litigation incidental to the conduct of its
business, none of which management believes is, individually or in the
aggregate, material to the Company's consolidated financial condition or results
of operations.

In connection with the GWDC Acquisition, a $5.0 million escrow fund was
established to provide a source of payment for the net costs to the Company, if
any, for any eventual settlement by, or the payment of a monetary court
judgement against the Company arising out of a case pending against GWDC at the
time of the GWDC Acquisition. The source of the escrow fund was the cash
consideration that would have otherwise been payable by the Company to GWDC's
shareholders. The litigation was styled TEPCO, Inc. ("TEPCO") v. Grey Wolf
Drilling (Cause no. 96-49194) and was filed in the 164th Judicial District Court
of Harris County, Texas. TEPCO alleged that Grey Wolf breached contractual
obligations it owed to TEPCO by failing to drill an oil and gas well or wells
for it in the Treasure Isle Field, located in Galveston, Texas. TEPCO also
alleged that it lost rights under an oil and gas lease it had under an alleged
agreement with Mobil Producing Texas and New Mexico, Inc., causing plaintiff to
suffer money damages. Grey Wolf had filed a counterclaim in the lawsuit for
approximately $154,000 for recovery of unpaid invoices, and interest, for
services rendered or materials provided by Grey Wolf in connection with the
drilling of two wells for TEPCO which were completed before Grey Wolf ceased
performing work for TEPCO. This case was settled in August 1997 for $2.5 million
which was paid from the escrow fund in October 1997, and the remaining $2.5
million less applicable expenses was distributed to the former GWDC
shareholders.

The GWDC Acquisition is intended to qualify as a tax free
reorganization under Sections 368(a)(1)(A) and 368(a)(2)(D) of the Internal
Revenue Code of 1986, as amended (the "Code"), with respect to common stock
received by GWDC shareholders. A principal condition for such qualification is
that the former shareholders of GWDC will satisfy the continuity of proprietary
interest standard with respect to common stock received in the GWDC Acquisition.
Thus, under present Internal Revenue Service ("IRS") guidelines, dispositions of
common stock by GWDC shareholders during the five years following the GWDC
Acquisition could cause the IRS to assert that the GWDC Acquisition does not
qualify as a tax free reorganization. The Company has no contractual agreements
with GWDC shareholders preventing the disposition of their shares. If the GWDC
Acquisition fails to qualify as a tax free reorganization for failure to meet
the continuity of interest standard or for any reason, the receipt of common
stock will be taxable to the GWDC shareholders at the time of the GWDC
Acquisition, and GWDC will be deemed to have sold all of its assets in


-46-

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


a taxable exchange triggering a corporate tax liability to GWDC estimated to be
in excess of $30.0 million. The Company's wholly-owned subsidiary, Grey Wolf
Drilling Company (formerly Drillers, Inc.), as the surviving corporation of the
GWDC Acquisition, would be liable for any such corporate tax which, if imposed,
would have a material adverse effect on the financial condition of the Company.

(10) EMPLOYEE BENEFIT PLAN

The Company has a defined contribution employee benefit plan covering
substantially all of its employees. Prior to 1997, the Company matched
individual employee contributions up to 2% of the employee's compensation.
Effective January 1, 1997, the Company increased the matching provisions to
include matching 100% of the first 3% of individual employee contributions and
50% of the next 3% of individual employee contributions. Other provisions of the
plan were also amended. Employer matching contributions under the plan totaled
$852,000, $104,000 and $144,000 for the years ended December 31, 1997, 1996 and
1995. Employer matching contributions vest over a five year period.

(11) NON-RECURRING CHARGES

During the year ended December 31, 1996, the Company recorded
non-recurring charges of $6.1 million which included $1.1 million in employment
severance costs, $4.6 million in cost to exit the Argentina and Mexico markets
and $400,000 of other non-recurring charges. The employment severance cost
included $602,000 in contractual severance pay to be paid over a two year period
to the Company's former President and Chief Executive Officer and the transfer
to him of certain drilling equipment with a net book value of $535,000 in
settlement of a dispute over stock options to purchase the Company's common
stock. As a result of the Company's desire to redeploy assets to more profitable
markets, the Company withdrew from both the Argentina and Mexico markets. As a
result, during 1996, the Company recorded estimated exit costs of $1.3 million
for Mexico which primarily consisted of the forfeiture of a performance bond and
other costs incurred to close the office and exit the market and exit costs of
$800,000 for Argentina which primarily consisted of costs incurred during the
period necessary to close the office and exit the market. In addition, the
Company sold three of the six drilling rigs and certain other assets located in
Argentina for $1.5 million. As a result, during 1996 the Company recorded a
write down of rig equipment and other assets of $2.5 million. The remaining
Argentina rigs were mobilized to the United States, where they were refurbished
and returned to work. Mobilization costs were approximately $900,000 and were
expensed as they were incurred during 1997.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND
FINANCIAL DISCLOSURE

Deloitte & Touche LLP was previously the principal accountants for Grey
Wolf, Inc. On October 2, 1996, that firm's appointment as principal accountants
was terminated and KPMG Peat Marwick LLP was engaged as principal accountants.
The decision to change accountants was approved by the Board of Directors upon
recommendation of the Audit Committee of the Board of Directors.

In connection with the audits of the two fiscal years ended December 31,
1995, and the subsequent interim period through June 30, 1996, there were no
disagreements with Deloitte & Touche LLP on any matter of accounting principles
or practices, financial statement disclosure, or auditing scope or procedures,
which disagreements if not resolved to their satisfaction would have caused them
to make reference in connection with their opinion to the subject matter of the
