     Nabors Industries, Inc. and Bayard Drilling Technologies, Inc. have entered
into a merger agreement which provides that Nabors will acquire Bayard through a

converted into the right to receive:
 
     - 0.3375 shares of Nabors common stock; and
 
     - $0.30 in cash.
 
     After the merger, the former stockholders of Bayard will own approximately
5.7% of the outstanding shares of Nabors common stock. Nabors common stock
trades on the American Stock Exchange under the symbol "NBR."
 
     THE BAYARD BOARD HAS UNANIMOUSLY DETERMINED THAT THE MERGER AGREEMENT, THE
MERGER AND RELATED TRANSACTIONS, TAKEN TOGETHER, ARE ADVISABLE AND IN THE BEST
INTERESTS OF, AND ARE FAIR TO, THE STOCKHOLDERS OF BAYARD. ACCORDINGLY, THE
BAYARD BOARD HAS UNANIMOUSLY APPROVED THE MERGER AGREEMENT AND THE MERGER AND
UNANIMOUSLY RECOMMENDS THAT ALL STOCKHOLDERS VOTE FOR ADOPTION OF THE MERGER
AGREEMENT.
 
     You are cordially invited to attend a special meeting of the stockholders
of Bayard to consider and vote upon the merger agreement. The merger agreement

majority of the outstanding shares of Bayard common stock.

                                    SUMMARY
 
     This summary is qualified by, and should be read along with, the more
detailed information contained in the rest of this document, including the
attached annexes and the financial statements and related notes included or
incorporated by reference into this document. We urge you to read all of these
materials carefully.
 
                                 THE COMPANIES
 
BAYARD DRILLING TECHNOLOGIES, INC.
 
     Bayard is a leading provider of contract land drilling services to major
and independent oil and gas companies. Since its incorporation in December 1996,
Bayard has grown from a regional competitor with ten rigs to the fifth largest
land drilling fleet operator in the United States. As of December 31, 1998,
Bayard's rig fleet consisted of 87 rigs, of which 73 were being actively
marketed and 14 were available for refurbishment. Bayard's fleet consists
primarily of rigs capable of drilling to well depths of 15,000 feet or greater.
Of Bayard's 87 rigs, 69 are capable of drilling to depths of 15,000 feet or
greater and 43 are capable of drilling to depths of 20,000 feet or greater.
Thirty-one of Bayard's 87 rigs are diesel electric silicon controlled rectifier
rigs, which utilize electric power to control drilling operations and are
commonly referred to as "SCR" rigs in the land drilling industry. The remainder
are mechanical rigs. Bayard's rig fleet is currently concentrated in three core
operating regions -- the Mid-Continent region, the Gulf Coast region and the
South Texas region. Bayard's principal executive offices are located at 4005
Northwest Expressway, Suite 550E, Oklahoma City, Oklahoma 73116, and its
telephone number is (405) 840-9550.
 
NABORS INDUSTRIES, INC.
 
     Nabors is the largest land drilling contractor in the world, with over 400
actively marketed land rigs as of November 30, 1998. Nabors conducts oil and gas
land drilling operations in North America, including the lower 48 United States,
Alaska and Canada, and internationally, primarily in South and Central America
and the Middle East. Offshore, Nabors markets 25 platforms, six jack-up and two
barge drilling rigs in the Gulf of Mexico, Alaska's Cook Inlet and several
international markets. To supplement its primary businesses, Nabors offers a
number of ancillary well-site services, including oilfield management,
engineering, transportation, construction, maintenance, well logging and other
support services, in selected domestic and international markets. In addition,
Nabors manufactures and leases or sells top drives for a broad range of drilling
rig applications and manufactures and leases or sells rig instrumentation
equipment to monitor rig performance. Nabors' principal executive offices are
located at 515 West Greens Road, Suite 1200, Houston, Texas 77067, and its
telephone number is (281) 874-0035.
 
     On January 10, 1999, Nabors entered into an agreement and plan of merger to
acquire Pool Energy Services Co., an energy services company principally engaged
in providing well-servicing, workover and drilling services and related
transportation services on land and offshore in the United States and selected
international markets. Pool's rig fleet includes approximately 750 land
well-servicing workover rigs, 29 land drilling rigs and 27 offshore rigs. The
consummation of the Pool merger transaction is subject to customary closing
conditions, including regulatory approval and the approval of holders of at
least two-thirds of Pool shares. The agreement provides for Nabors to issue
1.025 shares of Nabors common stock for each outstanding Pool share not already
owned by Nabors and assume approximately $144 million of debt. Based on the
number of Pool shares outstanding on January 10, 1999, upon consummation of the
Pool merger transaction Nabors would issue approximately 19 million shares of
Nabors common stock which, on the last trading date before the announcement of
the Pool merger agreement, had a value of approximately $305 million.

                                   THE MERGER
 
GENERAL
 
     Nabors will acquire Bayard in the merger. Bayard will continue in existence
after the merger as a wholly owned subsidiary of Nabors.
 
TREATMENT OF BAYARD COMMON STOCK
 
     In the merger, each issued and outstanding share of Bayard common stock,
except for shares held by persons who properly exercise dissenters' appraisal
rights, will be converted into the right to receive:
 
     - 0.3375 shares of Nabors common stock; and
 
     - $0.30 in cash, without interest.
 
See "The Merger Agreement and Related Agreements -- Conversion of Securities."
 
OPINION OF BAYARD'S FINANCIAL ADVISOR
 
     DLJ acted as financial advisor to Bayard in connection with the merger. DLJ
has rendered its opinion to the Bayard Board of Directors that, as of February
12, 1999, and subject to the assumptions, limitations and qualifications
contained in the opinion, the consideration to be received by the stockholders
of Bayard under the merger agreement was fair to such stockholders from a
financial point of view. DLJ's written opinion is attached to this document as
Annex B. Bayard's stockholders should read this entire opinion carefully.
 
RECOMMENDATION OF THE BAYARD BOARD
 
     The Bayard Board has unanimously determined that the merger agreement, the
merger and related transactions, taken together, are advisable and in the best
interests of, and are fair to, the stockholders of Bayard. The Bayard Board has
authorized and approved the merger agreement, subject to the approval of such
agreement by the stockholders of Bayard, and has unanimously recommended that
the stockholders of Bayard vote FOR adoption of the merger agreement.
 
     The Bayard Board based its determination and recommendation on the
following principal grounds:
 
     - its belief that the combination of the resources and operations of Bayard
       and Nabors is a good strategic fit, especially in view of the focus by
       both companies on technologically advanced rigs capable of deep drilling
       applications;
 
     - the fact that Nabors has been a strong financial performer historically,
       maintaining low levels of debt, while operating a large contract drilling
       fleet; and
 
     - its belief that Nabors, after giving effect to the acquisition of Bayard
       in the merger, will be a stronger company in the short-term and long-term
       than either Nabors or Bayard as an independent company.
 
See "The Merger -- Background of the Merger," "-- Reasons for the Merger" and
"-- Recommendation of the Bayard Board."
 
RIGHTS OF DISSENTING STOCKHOLDERS
 
     Stockholders of Bayard who wish to dissent from the merger will be entitled
to exercise appraisal rights granted under Section 262 of the Delaware General
Corporation Law. If you wish to exercise appraisal rights, you must comply with
the procedures set forth in Section 262. Stockholders who properly exercise
these appraisal rights will be entitled to obtain a determination by a Delaware
court of the "fair value" of their shares after the consummation of the merger.
A determination of "fair value" would
 
                                        2
<PAGE>   8
 
exclude any element of value arising from the accomplishment or expectation of
the merger. No one can predict the ultimate outcome of a judicial appraisal
proceeding.
 
     In order to exercise appraisal rights, you must, among other things:
 
     - not vote in favor of adoption of the merger agreement or deliver to
       Bayard a signed proxy card without express voting instructions;
 
     - deliver to Bayard, before the vote on the adoption of the merger
       agreement at the special meeting, a written demand for appraisal of your
       shares;
 
     - hold the shares in question on January 15, 1999, the record date for
       voting on the merger agreement, and continue to hold them through the
       date of consummation of the merger; and
 
     - file a petition in Delaware court, within 120 days after the merger,
       demanding a determination of the fair value of your shares.
 
For more detailed information regarding the requirements of Section 262 of the
Delaware General Corporation Law, see "The Merger -- Rights of Dissenting
Stockholders." In addition, the full text of Section 262 is attached to this
document as Annex C.
 
FEDERAL INCOME TAX CONSEQUENCES
 
     The merger will be treated as a reorganization for federal income tax
purposes. As a result, except with respect to cash received instead of
fractional shares, Bayard stockholders:
 
     - will not recognize any loss as a result of the merger; and
 
     - will recognize gain as a result of the merger only to the extent of the
       lesser of the cash consideration received or the excess, if any, of the
       value of the total consideration received over the stockholder's tax
       basis in the Bayard common stock.
 
Stockholders who sell shares of Bayard common stock in the market before the
merger will generally recognize capital gain or loss in an amount equal to the
difference between the amount received in the sale and the stockholder's tax
basis in the shares that are sold. See "Federal Income Tax Consequences."
 
     Bayard and Nabors base these statements on a number of assumptions that are
more fully described in "Federal Income Tax Consequences," including the
assumption that, as of the date of the merger, Nabors common stock will continue
to represent at least 80% of the value of the total consideration furnished by
Nabors in the merger.
 
GRANT OF 19.9% LOCK-UP OPTION; EFFECT ON COMPETING OFFERS
 
     At the time that the merger agreement was executed, Bayard and Nabors also
entered into a stock option agreement. The existence of the stock option
agreement could deter third parties from making offers to Bayard for competing
acquisition transactions by making such transactions more expensive or difficult
to consummate. The stock option agreement gives Nabors the right to purchase up
to 19.9% of the outstanding shares of Bayard common stock at a price of $5.50
per share. However, Nabors may purchase such shares only if the merger agreement
is terminated for specified reasons, including the following:
 
     - the stockholders of Bayard fail to adopt the merger agreement, and within
       180 days after the termination of such agreement, Bayard authorizes or
       announces an intention to enter into a competing acquisition transaction;
 
     - Bayard intentionally breaches any of its covenants or agreements
       contained in the merger agreement;
 
                                        3
<PAGE>   9
 
     - the representations and warranties of Bayard contained in the merger
       agreement are or become untrue;
 
     - the Bayard Board withdraws its recommendation of the merger agreement or
       recommends that a competing acquisition proposal be adopted by the
       stockholders of Bayard; or
 
     - the Bayard Board determines that proceeding with the merger would be
       inconsistent with its fiduciary duties because of the existence of a
       competing acquisition proposal.
 
The Bayard Board determined to enter into the stock option agreement because it
believed such an agreement was necessary to obtain Nabors' agreement to other
favorable terms, including the favorable exchange ratio at which Bayard common
stock is to be converted into Nabors common stock. See "Risk Factors -- The
19.9% lock-up option Bayard granted to Nabors may deter or delay competing
offers" and "The Merger Agreement and Related Agreements -- Stock Option
Agreement."
 
PROHIBITION ON SOLICITATION OF COMPETING TRANSACTIONS
 
     So long as the merger agreement is in effect, Bayard is prohibited from
initiating, soliciting or encouraging the submission of any proposal by, or
entering into any discussions or negotiations with, a third party relating to a
competing acquisition transaction. A competing acquisition transaction includes
any of the following:
 
     - a merger or consolidation of Bayard or its subsidiaries;
 
     - the sale or other disposition of all or substantially all of the
       properties and assets of Bayard or any other material properties and
       assets; or
 
     - a tender or exchange offer for more than 15% of the outstanding shares of
       Bayard common stock.
 
     If, however, the Bayard Board, after consulting with legal counsel,
determines in good faith that it must do so in order to comply with its
fiduciary duties, then Bayard may, in response to an unsolicited competing
acquisition proposal meeting specified criteria, participate in discussions and
negotiations regarding the proposal. See "The Merger Agreement and Related
Agreements -- Covenants -- No Solicitation."
 
CONDITIONS TO THE MERGER
 
     The conditions to the obligations of all parties to consummate the merger
include:
 
     - the adoption of the merger agreement by the stockholders of Bayard;
 
     - the expiration or termination of the waiting period under the
       Hart-Scott-Rodino Antitrust Improvements Act of 1976; and
 
     - the absence of any injunction or other legal restraint prohibiting the
       merger.
 
     The conditions to the obligations of each party to consummate the merger
include:
 
     - that the other party not have suffered a material adverse effect in its
       business or operations since the date of the merger agreement;
 
     - that the representations and warranties of the other party in the merger
       agreement be true, except where the failure to be true would not have a
       material adverse effect on the other party; and
 
     - that the other party have complied in all material respects with its
       covenants in the merger agreement.

<PAGE>   10
 
TERMINATION; FEES AND EXPENSES
 
     The merger agreement may be terminated if any of the following occurs:
 
     - the merger agreement is not adopted by Bayard's stockholders;
 
     - either Bayard or Nabors intentionally breaches any of its covenants or
       agreements contained in the merger agreement;
 
     - the representations and warranties of Bayard or Nabors contained in the
       merger agreement are or become untrue;
 
     - the merger is not consummated by September 30, 1999;
 
     - the Bayard Board withdraws its recommendation of the merger agreement or
       recommends that a competing acquisition proposal be adopted by the
       stockholders of Bayard; or
 
     - the Bayard Board determines that proceeding with the merger would be
       inconsistent with its fiduciary duties because of the existence of a
       competing acquisition proposal.
 
If the merger agreement is terminated under specified circumstances, then either
Bayard or Nabors may become obligated to make a payment to the other party. In
particular, if the merger agreement is terminated because a party breaches a
covenant, agreement, representation or warranty, then the breaching party must
make a payment in cash to the other party in the amount of $7.5 million (if
Bayard is the breaching party) or $15.0 million (if Nabors is the breaching
party). If the merger agreement is terminated for specified reasons involving a
competing acquisition proposal, Bayard must make a payment to Nabors in the
amount of $5.0 million, plus up to $500,000 for reasonable third party costs.
See "The Merger Agreement and Related Agreements -- Termination" and " -- Fees,
Expenses and Other Payments."
 
CLOSING
 
     Bayard and Nabors expect to consummate the merger promptly after the
conditions to closing set forth in the merger agreement are fulfilled or waived.
It is anticipated that the last of the conditions to be fulfilled will be either
the expiration or termination of the waiting period under the Hart-Scott-Rodino
Antitrust Improvements Act of 1976 or the adoption of the merger agreement by
the Bayard stockholders. Bayard and Nabors are working towards completing the
merger as quickly as possible and expect to consummate this transaction early in
the second quarter of 1999. See "The Merger -- Effective Time."
 
SURRENDER OF STOCK CERTIFICATES; PAYMENT FOR SHARES
 
     Promptly after the merger is consummated, Nabors will mail a transmittal
form to each record holder of shares of Bayard common stock, describing the
procedure for surrendering Bayard stock certificates. STOCKHOLDERS SHOULD NOT
SEND IN THEIR STOCK CERTIFICATES UNTIL THEY RECEIVE A TRANSMITTAL FORM.
Stockholders who submit their certificates and a completed transmittal form will
receive:
 
     - the cash portion of the consideration to be paid by Nabors;
 
     - certificates for the whole number of shares of Nabors common stock which
       the holder has the right to receive; and
 
     - cash instead of fractional shares of Nabors common stock.
 
No interest will be paid on any cash payable upon surrender of certificates. See
"The Merger -- Exchange of Certificates" and "The Merger Agreement and Related
Agreements -- Conversion of Securities."

                              THE SPECIAL MEETING
 
GENERAL
 
     The special meeting of the stockholders of Bayard will be held at the date,
time and place set forth on the cover page of this document.
 
PURPOSE OF THE SPECIAL MEETING
 
     At the special meeting, the stockholders of Bayard will vote on whether to
adopt the merger agreement. THE BAYARD BOARD UNANIMOUSLY RECOMMENDS THAT THE
STOCKHOLDERS OF BAYARD VOTE FOR THE ADOPTION OF THE MERGER AGREEMENT.
 
RECORD DATE; REQUIRED VOTE
 
     The Bayard Board has fixed the close of business on January 15, 1999 as the
record date for determining which stockholders are entitled to notice of, and to
vote at, the special meeting. Only holders of record of shares of Bayard common
stock on the record date will be entitled to vote at the special meeting.
 
     As of the record date, there were 18,200,765 shares of Bayard common stock
issued and outstanding. The presence, in person or by proxy, of holders of
record of 9,100,383 shares, representing a majority of the outstanding shares of
Bayard common stock, will constitute a quorum at the special meeting for
purposes of adopting the merger agreement. The affirmative vote of holders
representing a majority of the outstanding shares of Bayard common stock is
required to adopt the merger agreement. See "The Special Meeting -- Record Date;
Shares Entitled to Vote" and "-- Quorum."
 
VOTING YOUR SHARES
 
     Holders of shares of Bayard common stock are entitled to one vote for each
share held. Stockholders need not be physically present at the special meeting
to vote their shares. Instead, stockholders may simply mail their signed proxy
cards in the enclosed return envelopes.
 
     If a stockholder's shares are held in "street name" by a broker, the
stockholder should instruct the broker to vote the shares. If the stockholder
does not instruct the broker to vote, the broker will have no discretion to vote
the shares on its own.
 
     Stockholders who mail signed proxy cards can change their votes at any time
before their proxy cards are voted at the special meeting. Stockholders can do
this in any of the following ways:
 
     - send a written statement to the Secretary of Bayard revoking the proxy
       card;
 
     - send a new proxy card to the Secretary of Bayard; or
 
     - attend the special meeting and vote in person.
 
SHARES OWNED BY BAYARD MANAGEMENT; STOCKHOLDER AGREEMENTS
 
     As of the record date, directors and executive officers of Bayard and their
affiliates were beneficial owners of an aggregate of 2,687,740 shares of Bayard
common stock, excluding shares purchasable upon exercise of options or warrants.
Such shares represent approximately 14.8% of the total shares then outstanding.
 
     As an inducement to Nabors entering into the merger agreement, certain
directors of Bayard and their affiliates, who as of the record date held the
right to vote approximately 14.5% of the shares of Bayard common stock, have
entered into agreements with Nabors requiring these stockholders to vote in
favor of the adoption of the merger agreement. These stockholders are James E.
Brown, Carl B. Anderson, III, AnSon Partners L.L.C., Energy Spectrum Partners LP
and Wil-Cas Investments, L.P. The remaining directors and executive officers of
Bayard have indicated that they also intend to vote the shares
                                        6
<PAGE>   12
 
beneficially owned by them in favor of the adoption of the merger agreement. See
"The Merger Agreement and Related Agreements -- The Stockholder Agreements."
 
OFFICERS' AND DIRECTORS' INTERESTS IN THE MERGER
 
     Some of Bayard's officers and directors may have interests in the merger
that differ from the interests of the Bayard stockholders generally. For
example:
 
     - Nabors has agreed to cause one of its subsidiaries to hire James E.
       Brown, the Chairman of the Board, President and Chief Executive Officer
       of Bayard, as the subsidiary's Vice President -- Central Division. Under
       the terms of the proposed employment agreement, Mr. Brown would receive a
       $300,000 signing bonus, options for 200,000 shares of Nabors common stock
       and an annual base salary of $175,000.
 
     - Merrill A. Miller, Jr., a director of Bayard, is an officer of National
       Oilwell, L.P., a company that has conducted a significant amount of
       business with Nabors. National Oilwell, L.P. has advised Bayard that
       Nabors is one of its top ten customers in terms of revenue.
 
     - Existing indemnification arrangements for Bayard's directors and officers
       will continue in effect after the merger.
 
See "The Merger -- Interests of Certain Persons in the Merger."

                                  RISK FACTORS
 
     In determining whether to vote to adopt the merger agreement, stockholders
should carefully consider the matters set forth under "Risk Factors," among
others.
 
                           FORWARD-LOOKING STATEMENTS
 
     The statements in this document and the documents incorporated by reference
that relate to matters that are not historical facts are "forward-looking
statements" within the meaning of Section 27A of the Securities Act of 1933 and
Section 21E of the Securities Exchange Act of 1934. When used in this document,
words such as "anticipate," "believe," "expect," "plan," "intend," "estimate,"
"project," "will," "could," "may," "predict" and similar expressions are
intended to identify forward-looking statements. Future events and actual
results may differ materially from the results set forth in or implied in the
forward-looking statements. Factors that might cause such a difference include
the following: fluctuations in worldwide prices and demand for oil and gas,
fluctuations in levels of oil and gas exploration and development activities,
fluctuations in the demand for contract drilling services, the existence of
competitors, technological changes and developments in the industry, the
existence of operating risks inherent in the contract drilling industry, the
existence of regulatory uncertainties, the possibility of political instability
in any of the countries in which Bayard and Nabors do business, year 2000 issues
and general economic conditions, in addition to the other matters discussed
under "Risk Factors." In addition, actual benefits resulting from the merger may
be less than those anticipated by the two companies as a result of unanticipated
events that may occur in the integration of the business of Bayard into the
business of Nabors.

  SUMMARY SELECTED HISTORICAL AND UNAUDITED PRO FORMA COMBINED FINANCIAL DATA
 
     The following tables present selected historical financial data of Nabors
and Bayard and unaudited selected pro forma combined financial data after giving
effect to the acquisition of all of the outstanding capital stock of Bayard by
Nabors under the purchase method of accounting. The companies derived the data
for Nabors for each of the five fiscal years ended September 30, 1997 and the
data for Bayard or its predecessors for each of the four years ended December
31, 1997 from audited financial statements filed in each company's Annual
Reports on Form 10-K. The companies derived the data for Bayard for the year
ended December 31, 1993 from unaudited financial statements. The companies
derived the data for the nine months ended September 30, 1998 and 1997 from
unaudited financial statements filed in each company's Quarterly Report on Form
10-Q. In the opinion of management of Nabors and Bayard, such unaudited
financial statements contain all adjustments, consisting only of normal
recurring adjustments, necessary to present fairly the financial position and
results of operations of such interim periods.
 
     The historical financial data for Bayard for the year ended December 31,
1997 include the results of Bayard's consolidated subsidiaries as follows: Trend
Drilling Co., beginning May 1, 1997; Ward Drilling Company, Inc., beginning May
30, 1997; and Bonray Drilling Corporation, beginning October 16, 1997. The
historical financial data for Bayard for the three years ended December 31, 1996
relate to the operations of Anadarko Drilling Company, the predecessor of
Bayard, and generally include the financial results of the operation of eight
rigs. The selected historical financial data for each entity coincides with its
respective historical annual reporting period. Nabors changed its fiscal year
end from September 30 to December 31, effective for the fiscal year beginning
January 1, 1998. A three-month transition period from October 1, 1997 through
December 31, 1997 preceded the start of Nabors' new fiscal year. Nabors has
recast its financial data to conform to the presentation of the twelve months
ended December 31, 1997 by adjusting its audited results for the year ended
September 30, 1997 to exclude the unaudited results for the quarter ended
December 31, 1996 and to include the unaudited results for the quarter ended
December 31, 1997. Upon consummation of the merger, the fiscal year of the
combined company will end on December 31.
 
     The companies derived or prepared the unaudited selected pro forma combined
financial data consistently with the unaudited pro forma combined condensed
financial statements included in this document. The unaudited selected pro forma
combined financial data does not indicate what the combined results of
operations of Nabors and Bayard would have been had the merger occurred as of
the dates indicated or the results of operations that the combined company may
obtain in the future. The unaudited selected pro forma combined financial data
does not reflect the anticipated cost savings resulting from integration of the
operations of Nabors and Bayard.
 
     Stockholders should read the following selected historical and unaudited
pro forma combined financial data in conjunction with the historical and pro
forma combined financial statements and notes incorporated by reference or
included in this document.

                                  RISK FACTORS
 
     In addition to the other information contained or incorporated by reference
in this document, the stockholders of Bayard should carefully consider the
following risk factors before submitting a proxy card or voting at the special
meeting.
 
RISKS RELATING TO THE TRANSACTION
 
     Changes in the relationship between the Bayard common stock trading price
and the Nabors common stock trading price may cause the value of the merger
consideration to decrease. The merger agreement does not provide Bayard
stockholders with any protection against changes in the relative prices of
Nabors common stock and Bayard common stock. The merger consideration of 0.3375
shares of Nabors common stock and $0.30 cash per share of Bayard common stock is
fixed by the merger agreement. As a result, neither the number of shares of
Nabors common stock to be issued in exchange for each share of Bayard common
stock nor the $0.30 cash per share of Bayard common stock will be adjusted. The
trading prices of Nabors common stock and Bayard common stock at the time that
the merger is consummated may vary from their prices at the date of this
document. If the trading price of the Nabors common stock decreases relative to
the trading price of the Bayard common stock or the trading price of the Bayard
common stock increases relative to the trading price of the Nabors common stock,
the value of the merger consideration may be less than would be expected based
on current prices. Nevertheless, there will be no adjustment to the merger
consideration in either circumstance. We encourage you to obtain current market
quotations for the shares of Bayard common stock and Nabors common stock.
 
     If Nabors breaches the merger agreement, its payments to Bayard may not
cover Bayard's losses. The merger agreement provides Bayard with limited
monetary remedies in the event that the merger agreement is terminated because
of a breach by Nabors. Under certain circumstances, the limited monetary
remedies could be significantly less than Bayard's actual damages arising out of
the breach. Furthermore, if the merger agreement is terminated, Bayard may be
unable to procure another bidder that will offer to Bayard's stockholders
consideration of equivalent value to the merger consideration. The merger
agreement provides that if it is terminated by Bayard because:
 
     - Nabors intentionally breaches any covenant or agreement set forth in the
       merger agreement; or
 
     - any material representation or warranty of Nabors in the merger agreement
       is or becomes untrue, unless there is no material adverse effect on
       Nabors;
 
then Bayard's sole remedy will be to receive a payment from Nabors in the amount
of $15.0 million in cash. See "The Merger Agreement and Related
Agreements -- Termination" and "-- Fees, Expenses and Other Payments."
 
     The termination fee may deter potentially more favorable competing offers;
if Bayard must pay the termination fee, the payment will reduce its cash and
could reduce the trading price for its common stock. If the merger agreement is
terminated under specified circumstances, Bayard will be obligated to pay Nabors
a termination fee of $5.0 million, plus up to $500,000 for third party expenses.
This fee may deter third parties from making offers to acquire Bayard in a
competing acquisition transaction. Furthermore, the payment of such a fee would
reduce Bayard's cash and could result in a lower trading price for Bayard common
stock. The principal circumstances under which Bayard would be required to pay
the termination fee include if:
 
     - the Bayard stockholders fail to adopt the merger agreement at the special
       meeting;
 
     - the Bayard Board withdraws or adversely amends its recommendation that
       the Bayard stockholders vote to adopt the merger agreement;
 
     - the Bayard Board recommends that the stockholders vote for, fails to
       recommend that the stockholders vote against, or takes no position with
       respect to, a competing acquisition proposal; or
 
                                       10
<PAGE>   16
 
     - Bayard takes action under its stockholder rights plan to allow a person
       other than Nabors to acquire beneficial ownership of 15% of Bayard's
       common stock without triggering the provisions of such plan.
 
See "The Merger Agreement and Related Agreements -- Termination" and " -- Fees,
Expenses and Other Payments."
 
     The 19.9% lock-up option Bayard granted to Nabors may deter or delay
competing offers. Bayard has granted to Nabors the option to acquire up to 19.9%
of the total number of outstanding shares of Bayard common stock at a per share
exercise price of $5.50. This option may deter third parties from making offers
to Bayard to enter into an acquisition transaction. In addition, Nabors'
exercise of its rights may delay the consummation of, or make it more difficult
or expensive to consummate, a competing acquisition transaction. One
circumstance under which the option would become exercisable is if the merger
agreement is terminated as a result of the failure of the Bayard stockholders to
adopt the merger agreement and, within 180 days after the termination of the
merger agreement, Bayard authorizes, or announces an intention to enter into, a
competing acquisition transaction with a third party. A competing acquisition
transaction includes a merger, a sale of material assets or a tender offer for
15% or more of the outstanding shares of Bayard common stock. See "The Merger
Agreement and Related Agreements -- Stock Option Agreement."
 
RISKS RELATING TO NABORS AND ITS BUSINESS
 
     If the merger agreement is adopted by the stockholders of Bayard and the
merger is consummated, the stockholders of Bayard will receive shares of Nabors
common stock and cash. Ownership of Nabors common stock involves risks and
uncertainties. In determining whether to adopt the merger agreement, Bayard
stockholders should consider the following risks associated with an investment
in Nabors common stock. The existence of these risks may materially and
adversely affect Nabors business, results of operations and financial condition.
 
     Decreased oil and gas prices could adversely affect drilling activity and
Nabors' revenues, cash flows and profitability. Nabors' operations are
materially dependent upon the level of activity in oil and gas exploration and
production. Both short-term and long-term trends in oil and gas prices affect
the level of such activity. Oil and gas prices and, therefore, the level of
drilling, exploration and production activity, can be volatile. Worldwide
military, political and economic events, including initiatives by the
Organization of Petroleum Exporting Countries, affect both the demand for, and
the supply of, oil and gas. Fluctuations during the last year in the demand and
supply of oil and gas have contributed to, and are likely to continue to
contribute to, price volatility. Nabors believes that any prolonged reduction in
oil and gas prices would depress the level of exploration and production
activity. This would likely result in a corresponding decline in the demand for
Nabors' services and could have a material adverse effect on Nabors' revenues,
cash flows and profitability. There can be no assurances as to the future level
of demand for Nabors' services or future conditions in the drilling industry.
Beginning in early 1998, domestic land drillers, including Nabors, experienced a
significant downturn in demand for their drilling rigs. Nabors believes the
downturn is attributable in large part to sharp drops in oil prices that began
in late 1997 and have continued through 1998 and into 1999. The decline in crude
oil prices negatively impacted the revenues of oil companies, who have responded
by reducing exploration and development activity. Decreased demand has adversely
affected Nabors by lowering utilization of Nabors' rigs and reducing the day
rates Nabors can charge for its rigs.
 
     Nabors operates in a highly competitive industry with excess drilling
capacity, which may adversely affect Nabors' results of operations. The drilling
and workover industry in which Nabors operates is very competitive. Contract
drilling companies compete primarily on a regional basis, and competition may
vary significantly from region to region at any particular time. In many markets
in which Nabors operates, the number of rigs available for use exceeds the
demand for rigs, resulting in price competition. Most drilling and workover
contracts are awarded on the basis of competitive bids, which also results in
intense price
 
                                       11
<PAGE>   17
 
competition. The land drilling market generally is more competitive than the
offshore drilling market because there are a larger number of rigs and
competitors.
 
     In all of the markets in which Nabors operates, price and the availability
and condition of equipment are the most significant factors in determining which
drilling contractor is awarded a job. Other factors include the availability of
trained personnel possessing the required specialized skills, the overall
quality of service and safety record and the ability to offer ancillary
services. In international markets, experience in operating in certain
environments and customer alliances also have been factors in the selection of
Nabors.
 
     Certain competitors are present in more than one of Nabors' regions,
although no one competitor operates in all of these areas. In the lower 48
United States, the next largest competitors have over 100 rigs, based on
industry reports, and several hundred competitors have smaller national,
regional or local rig operations. In the Alaska market, Nabors has approximately
six major competitors. In the Gulf of Mexico, Nabors is among approximately five
principal competitors providing workover/maintenance services. In Canada and
other offshore areas, Nabors competes with several companies of varying size,
many of which have more significant operations in those areas than Nabors.
Internationally, Nabors competes directly with various competitors at each
location where it operates. Nabors believes that the market for land drilling
contracts will continue to be competitive for the foreseeable future. Although
Nabors believes it has a strong competitive position in the domestic land
market, certain of its competitors internationally and offshore may be better
positioned in these markets and have newer and more desirable equipment,
allowing them to compete more effectively.
 
     The nature of Nabors' operations present inherent risks of loss that, if
not insured or indemnified against, could adversely affect its results of
operations. Nabors' operations are subject to many hazards inherent in the
drilling, workover and well servicing industries, including blowouts, cratering,
explosions, fires, loss of well control, loss of hole, damaged or lost drilling
equipment and damage or loss from inclement weather, any of which could result
in personal injury or death, damage to or destruction of equipment and
facilities, suspension of operations, environmental damage and damage to the
property of others. Nabors' offshore operations are also subject to the hazards
of marine operations including capsizing, grounding, collision, damage from
heavy weather or sea conditions and unsound bottom conditions. In addition,
Nabors' international operations are subject to risks of war, civil disturbances
or other political events. Generally, drilling contracts provide for the
division of responsibilities between a drilling company and its customer, and
Nabors seeks to obtain indemnification from its customers by contract for
certain of these risks. To the extent that Nabors is unable to transfer such
risks to customers by contract or indemnification agreements, Nabors seeks
protection through insurance which its management considers to be adequate.
However, there is no assurance that such insurance or indemnification agreements
will adequately protect Nabors against liability from all of the consequences of
the hazards described above. The occurrence of an event not fully insured or
indemnified against, or the failure of a customer to meet its indemnification
obligations, could result in substantial losses to Nabors. In addition, there
can be no assurance that insurance will be available to cover any or all of
these risks, or, even if available, that it will be adequate or that insurance
premiums or other costs will not rise significantly in the future, so as to make
such insurance prohibitive.
 
     The profitability of Nabors' international operations could be adversely
affected by war, civil disturbance or economic turmoil. Nabors' business is
subject to additional risks of loss associated with conducting business abroad.
Unlike Bayard, Nabors derives a significant portion of its business from
international markets, including major operations in Canada, the Middle East,
the former Soviet republics and South and Central America. These operations are
subject to various risks, including the risk of war, civil disturbances and
governmental activities, that may limit or disrupt markets, restrict the
movement of funds or result in the deprivation of contract rights or the taking
of property without fair compensation. In certain countries, Nabors' operations
may be subject to the additional risk of fluctuating currency values and
exchange controls. In the international markets in which Nabors operates, it is
subject to various laws and regulations that govern the operation and taxation
of its business and the import and export of its equipment from country to
country, the imposition, application and interpretation of which can prove to be
uncertain.
                                       12
<PAGE>   18
 
     Exposure to environmental liabilities could adversely affect Nabors'
results of operations. The drilling of oil and gas wells is subject to various
federal, state, local and foreign laws, rules and regulations. The cost to
Nabors of compliance with these laws and regulations may be substantial. For
example, federal law imposes specific design and operational standards on rigs
and platforms. Failure to comply with these requirements could subject Nabors to
substantial civil and criminal penalties as well as potential court injunctions.
In addition, federal law imposes a variety of regulations on "responsible
parties" related to the prevention of oil spills and liability for damages from
such spills. Nabors, as an owner and operator of onshore and offshore rigs, may
be deemed to be a responsible party under federal law. Federal law assigns
liability to a responsible party of oil removal costs and subjects a responsible
party to a variety of public and private damages. In some circumstances, federal
law imposes liability without regard to negligence or fault, resulting in
substantial costs to the party upon whom such liability is imposed. Nabors
generally tries to require its customers to contractually assume responsibility
for compliance with environmental regulations. However, Nabors is not always
successful in shifting all of these risks.
 
     Nabors could be adversely affected if it loses the services of Mr.
Isenberg, Mr. Petrello or Mr. Stratton. Nabors' business is dependent to a
significant extent upon the performance of certain key individuals, including
Eugene M. Isenberg, Anthony G. Petrello and Richard A. Stratton. Each of these
individuals has entered into an employment agreement with Nabors. The loss of
the services of Mr. Isenberg, Mr. Petrello or Mr. Stratton could have a material
adverse effect on Nabors.
 
     The market price of Nabors common stock could be adversely affected by the
sale of the large number of shares that are available for sale in the
future. The sale, or availability for sale, of substantial amounts of Nabors
common stock in the public market from the exercise of options and the
conversion of convertible notes could adversely affect the prevailing market
price of Nabors common stock and could impair Nabors' ability to raise
additional capital through the sale of equity securities. As of February 9,
1999, there were 100,792,426 shares of Nabors common stock outstanding. As of
that date, an additional 18,313,517 shares of Nabors common stock were reserved
for issuance under options and warrants and 9,517,132 shares of Nabors common
stock were reserved for issuance upon the conversion of convertible notes of
Nabors. The exercise of certain of these options may cause Nabors to issue to
the exercising holders additional options to purchase shares of Nabors common
stock at an exercise price equal to the fair market value of Nabors common stock
on the date of issuance, and Nabors may issue additional options in the future
under stock option plans or otherwise. Certain of the shares to be issued upon
the exercise of options may be "restricted securities," as that term is defined
in Rule 144 promulgated under the Securities Act of 1933.
 
     The absence of dividends limits the ability of stockholders to recognize a
return on an investment in Nabors common stock. Nabors does not anticipate that
it will pay any dividends on the shares of Nabors common stock in the
foreseeable future. Certain of Nabors' debt instruments restrict Nabors' ability
to pay dividends or to make certain other distributions to stockholders. If
Nabors does not pay dividends, holders of Nabors common stock will be required
to sell their shares to realize a return on their investment.
 
     Nabors has implemented anti-takeover measures that could prevent Nabors'
stockholders from recognizing a possible premium on their shares. Nabors has
implemented various measures which could hinder, delay or prevent a takeover of
Nabors. These anti-takeover measures could prevent Nabors' stockholders from
realizing a possible premium on their shares. The Board of Directors of Nabors
is divided into three classes of directors, with each class serving a staggered
three-year term. In addition, the Board of Directors of Nabors has the authority
to issue up to 10,000,000 shares of preferred stock and to determine the price,
voting and other rights, conversion ratios, preferences and privileges of that
stock without any vote or action by the holders of Nabors common stock. Although
Nabors has no present plans to issue shares of preferred stock, the classified
board and the ability of the Nabors Board to issue additional shares of
preferred stock may discourage, delay or prevent changes in control of Nabors
that are not approved by the Nabors Board.

                              THE SPECIAL MEETING
 
GENERAL
 
     This document is being furnished to stockholders of Bayard in connection
with the solicitation of proxies on behalf of the Bayard Board for use at the
special meeting of Bayard stockholders to be held on March 16, 1999 at the time
and place specified below, and at any reconvened meeting after any adjournment
or postponement of the special meeting.
 
NOTICE OF MEETING
 
     The special meeting will be held on March 16, 1999 at 10:00 a.m., local
time, at the Hotel Sofitel, located at 425 North Sam Houston Parkway East,
Houston, Texas 77060, to consider and vote upon:
 
     - a proposal to adopt the Agreement and Plan of Merger, dated as of October
       19, 1998, as amended on January 15, 1999 and February 12, 1999, by and
       among Nabors, Nabors Acquisition Corp. VII, a wholly owned subsidiary of
       Nabors formed for purposes of the acquisition, and Bayard, which provides
       for the merger of Nabors' acquisition subsidiary with and into Bayard;
       and
 
     - such other business as may properly come before the special meeting or
       any adjournment or postponement of such meeting.
 
     This notice is being given to holders of record of Bayard common stock at
the close of business on the record date. A complete list of such stockholders
will be available for examination by any stockholder for any purpose germane to
the special meeting at Bayard's Houston office, located at 600 Kendrick, Suite
C-29, Houston, Texas 77060, for a period of at least ten days before such
meeting.
 
     THE BAYARD BOARD HAS UNANIMOUSLY DETERMINED THAT THE MERGER AGREEMENT AND
THE MERGER AND THE OTHER TRANSACTIONS CONTEMPLATED BY SUCH AGREEMENT, TAKEN
TOGETHER, ARE ADVISABLE AND IN THE BEST INTERESTS OF, AND ARE FAIR TO, THE
STOCKHOLDERS OF BAYARD AND HAS UNANIMOUSLY APPROVED THE MERGER AGREEMENT AND THE
TRANSACTIONS CONTEMPLATED BY SUCH AGREEMENT. ACCORDINGLY, THE BAYARD BOARD
UNANIMOUSLY RECOMMENDS THAT ALL BAYARD STOCKHOLDERS VOTE FOR THE ADOPTION OF THE
MERGER AGREEMENT.
 
RECORD DATE; SHARES ENTITLED TO VOTE
 
     The Bayard Board has fixed the close of business on January 15, 1999 as the
record date for determining the Bayard stockholders entitled to receive notice
of and to vote at the special meeting. As of the record date, 18,200,765 shares
of Bayard common stock were outstanding and held of record by approximately 130
holders. Each outstanding share of Bayard common stock is entitled to one vote
on all matters coming before the special meeting. Bayard also has outstanding
warrants and stock options. The holders of these derivative securities have no
voting rights with respect to the merger agreement.
 
QUORUM
 
     A quorum is necessary in order for a vote to be taken on the proposals
presented at the special meeting. The presence, either in person or by proxy, of
the holders of 9,100,383 shares, representing a majority of the issued and
outstanding shares of Bayard common stock on the record date, is necessary to
constitute a quorum for the transaction of business at the special meeting.
 
VOTE REQUIRED
 
     Under Delaware law, the affirmative vote of the holders of at least
9,100,383 shares, representing a majority of the outstanding shares of Bayard
common stock, is required to adopt the merger agreement.
 
                                       16
<PAGE>   22
 
EFFECT OF ABSTENTIONS AND BROKER NON-VOTES
 
     The inspectors of election will treat shares of Bayard common stock
represented by properly executed proxies that reflect abstentions as shares that
are present and entitled to vote for purposes of determining the presence of a
quorum at the special meeting and for purposes of determining the outcome of any
question submitted to the stockholders for a vote. The inspectors of election
will treat "broker non-votes" as shares that are present and entitled to vote
for purposes of establishing a quorum. "Broker non-votes" are shares held by
brokers that are represented at a meeting but with respect to which the broker
has not received instructions from the customer or otherwise does not have
discretionary authority to vote. For purposes of determining the outcome of any
question as to which the broker has physically indicated on the proxy that it
does not have discretionary authority to vote, these shares will be treated as
not present and not entitled to vote with respect to that question, even though
those shares are considered entitled to vote for quorum purposes and may be
entitled to vote on other questions. Abstentions and broker non-votes will have
the same effect as votes against the adoption of the merger agreement.
 
VOTING OF PROXIES
 
     Shares of Bayard common stock represented by properly executed proxies
received at or before the special meeting, and which have not been revoked, will
be voted at the special meeting, or any reconvened meeting after any adjournment
or postponement of the special meeting, in accordance with the instructions of
such proxies. If a proxy is properly executed and returned by a stockholder of
Bayard without indicating any voting instructions, the shares of Bayard common
stock represented by such proxy will be voted at the special meeting FOR the
adoption of the merger agreement.
 
     If any other matters are properly presented for consideration at the
special meeting, including, among other things, consideration of a motion to
adjourn or postpone the special meeting to another time or place, then James E.
Brown and David E. Grose, III, the persons named on the enclosed proxy card as
the proxies for Bayard common stock, will have discretion to vote on these
matters in accordance with their best judgment.
 
REVOCATION OF PROXIES
 
     A stockholder executing and returning a proxy has the power to revoke it at
any time before it is exercised either by executing and delivering a later-dated
proxy to the Secretary of Bayard, by delivering a duly executed written
revocation of such proxy to the Secretary of Bayard, or by voting in person at
the special meeting. Attendance at the special meeting will not in and of itself
revoke a proxy.
 
SOLICITATION OF PROXIES; EXPENSES
 
     In connection with the special meeting, proxies are being solicited by, and
on behalf of, the Bayard Board. Bayard will bear the cost of the solicitation of
proxies from its stockholders; however, Nabors has agreed in the merger
agreement to bear one-half of the costs of filing, printing and mailing this
document. In addition to the solicitation of proxies by use of mail, the
directors, officers and employees of Bayard may solicit proxies from
stockholders personally or by telephone, facsimile or other means of
communication. Such directors, officers and employees will not be additionally
compensated for such solicitation but may be reimbursed for out-of-pocket
expenses incurred in connection with the solicitation. In addition, Bayard has
engaged Morrow & Co., Inc. for a fee of $6,500, plus expenses, to aid in the
solicitation of proxies and to verify certain records related to the
solicitation. Arrangements will also be made with brokerage houses, banks,
fiduciaries and other custodians for the forwarding of solicitation material to
the beneficial owners of stock held of record by such persons, and Bayard will
reimburse such persons for their reasonable out-of-pocket expenses in connection
with the solicitation.
 
     STOCKHOLDERS SHOULD NOT SEND IN THEIR STOCK CERTIFICATES WITH THEIR PROXY
CARD.

SHARES HELD BY BAYARD MANAGEMENT; STOCKHOLDER AGREEMENTS
 
     As of the record date, the directors and executive officers of Bayard as a
group may be deemed to own beneficially an aggregate of 2,687,740 outstanding
shares of Bayard common stock. This amount excludes shares purchasable upon the
exercise of outstanding options or warrants and represents approximately 14.8%
of the total shares outstanding as of the record date.
 
     As a condition and an inducement to Nabors entering into the merger
agreement, James E. Brown, Carl B. Anderson, III, AnSon Partners L.L.C., Energy
Spectrum Partners LP, and Wil-Cas Investments, L.P., who are directors of the
Company or entities affiliated with directors, have entered into stockholder
agreements with Nabors. These individuals and entities are sometimes referred to
in this document as the "consenting stockholders." The stockholder agreements
were approved by the Bayard Board and require the consenting stockholders to
vote all of their shares of Bayard common stock for the adoption of the merger
agreement and against any competing acquisition transaction. As of the record
date, these stockholders beneficially owned in the aggregate a total of
2,645,725 outstanding shares of Bayard common stock. This amount represents
approximately 14.5% of the total shares outstanding as of the record date. In
addition, the remaining directors and executive officers of Bayard have
indicated that they intend to vote shares beneficially owned by them in favor of
the proposal to adopt the merger agreement.

                                   THE MERGER
 
GENERAL
 
     Bayard, Nabors and Nabors' acquisition subsidiary have entered into the
merger agreement, which provides that Nabors will acquire Bayard and each
outstanding share of Bayard common stock will be converted into the right to
receive (a) 0.3375 shares of Nabors common stock, and (b) $0.30 in cash, without
interest. Bayard will be the surviving corporation in the merger and will become
a wholly owned subsidiary of Nabors.
 
BACKGROUND OF THE MERGER
 
     Bayard was formed in December 1996 through a series of affiliated entity
transactions in which Bayard became the successor to Anadarko Drilling Company,
the contract drilling subsidiary of AnSon Partners Limited Partnership. From May
1997 through October 1997, Bayard completed three significant acquisitions which
increased its land drilling fleet by a total of 33 additional rigs.
 
     Before November 1997, Bayard received overtures from two other major
contract drilling companies, Company A and Company B, who expressed interest in
a business combination with Bayard. At the time, Bayard rejected these overtures
because the Bayard Board believed that its business objectives could best be
achieved through an initial public offering of its securities.
 
     On November 7, 1997, Bayard completed its initial public offering of shares
of Bayard common stock. In its initial public offering, Bayard and certain of
its existing and former stockholders sold an aggregate of 11,040,000 shares of
Bayard common stock to the public through an underwriting syndicate led by DLJ.
The initial public offering price was $23.00 per share.
 
     Since November 1997, Bayard and other drilling companies have experienced
the effects of weakening demand for contract drilling services, primarily as a
result of declines in oil and gas prices and a reduction in oil and gas
exploration and development activity. As a result of these conditions, Bayard's
rig utilization rates declined from approximately 93% in 1997 to 48% for the
three months ended September 30, 1998. Due in large part to conditions affecting
the land drilling industry, the market price of Bayard common stock experienced
a pronounced decline from the initial public offering price of $23.00 per share
to a low of approximately $3.63 in early October 1998.
 
     On various occasions during the first six months of 1998, Bayard was
contacted by Company A concerning its interest in a business combination with
Bayard. On each occasion, Bayard elected not to pursue a business combination
with Company A because management believed that such a transaction was
inconsistent with Bayard's strategic direction. This concern related primarily
to the fact that the company resulting from a combination of Bayard and Company
A would be subject to a substantial degree of financial leverage and would not
have significant operations outside of the continental United States.
 
     In May 1998, Nabors made an unsolicited overture to Bayard regarding a
possible business combination between Bayard and Nabors. Bayard elected not to
pursue this initial overture by Nabors.
 
     On June 26, 1998, Bayard acquired 25 additional land drilling rigs from
TransTexas Gas Corporation. In order to finance the acquisition of these rigs,
Bayard issued $100 million of Senior Notes due 2005 in a private placement under
Rule 144A under the Securities Act of 1933. As a result of this acquisition,
Bayard established a significant presence in the South Texas land drilling
market. However, the related senior notes offering resulted in a significant
increase in Bayard's financial leverage and heightened its exposure to adverse
conditions in the domestic land drilling industry.
 
     In July 1998, management of Bayard determined that, in light of the
continued adverse conditions in the domestic land drilling industry, it should
consider new initiatives in order to ensure that Bayard would be able to
continue to execute its business strategy. Among the initiatives considered by
management were a private placement of equity securities to raise additional
working capital and a business combination with another large contract drilling
company. The perceived advantages of a business combination included
 
                                       19
<PAGE>   25
 
greater financial resources, increased revenue development opportunities,
increased economies of scale and other cost saving opportunities.
 
     In August 1998, James E. Brown, Chairman of the Board, President and Chief
Executive Officer of Bayard, contacted Company B to discuss whether Company B
may have an interest in exploring a possible business combination with Bayard.
In preliminary discussions between the parties, Mr. Brown and senior management
of Company B discussed the feasibility of such a business combination and the
relative valuations that might be placed on the companies' businesses. Neither
company made a proposal as to the financial terms of a business combination, and
discussions between the parties terminated in August 1998.
 
     On August 21, 1998, Bayard entered into a rights agreement with Norwest
Bank Minnesota, N.A., as rights agent, in order to protect against the potential
of abusive takeover tactics. In light of the adverse conditions in the domestic
land drilling industry, the Bayard Board believed that Bayard might at that time
be particularly vulnerable to an inadequate takeover offer. At the time the
Bayard rights agreement was adopted, the market price of Bayard common stock had
declined over the prior three months from a high of approximately $12.00 to a
low of less than $5.00.
 
     In late September 1998, Mr. Brown was contacted by senior management of
Company A who stated that Company A still had an interest in pursuing a business
combination with Bayard. On October 2, 1998, a member of the senior management
of Company A met with Mr. Brown and made a preliminary proposal regarding a
stock-for-stock merger between the two companies. Under the terms of this
preliminary proposal, shares of Bayard common stock would have been converted
into shares of Company A common stock at an exchange ratio based upon a premium
of approximately 35% to the then market price of Bayard common stock. Mr. Brown
responded that he believed that the terms proposed by Company A would not be
acceptable to the Bayard Board, but indicated that he would discuss the matter
with members of the Bayard Board.
 
     On October 1, 1998, Bayard received a proposal from an investment fund,
Fund A, which contemplated an investment of approximately $20 to $25 million in
Bayard in the form of a new series of preferred stock that would be convertible
into Bayard common stock at an effective price of $5.50 per share. The directors
of Bayard were advised of the terms of this proposal, and a meeting of the
Bayard Board was scheduled to be held on October 7, 1998 to review this proposal
and any other proposals regarding strategic transactions received by Bayard.
 
     On October 1, 1998, Eugene M. Isenberg, Chairman of the Board of Nabors,
contacted Mr. Brown and stated that he would like to meet with Mr. Brown to
discuss the strategic directions of Bayard and Nabors. Mr. Brown invited Mr.
Isenberg to meet with him on October 6, 1998.
 
     On October 6, 1998, Mr. Brown met with Mr. Isenberg. Mr. Isenberg proposed
to Mr. Brown a merger between Nabors and Bayard in which the stockholders of
Bayard would receive shares of Nabors common stock based on an exchange ratio
representing a substantial premium to the recent trading ratios of the stocks of
the two companies. Later that day, Mr. Brown consulted with certain directors of
Bayard regarding the transaction proposed by Nabors. In telephone conversations
taking place in the afternoon on October 6, 1998 and the morning of October 7,
1998, Mr. Brown and Mr. Isenberg discussed possible exchange ratios for a
stock-for-stock merger between the two companies. At the conclusion of these
conversations, Mr. Isenberg proposed that the two companies be merged based on
an exchange ratio of 0.375 shares of Nabors common stock for each share of
Bayard common stock. Mr. Brown responded that he would discuss this proposal
with the Bayard Board.
 
     At the meeting of the Bayard Board held on October 7, 1998, the Bayard
Board considered the strategic alternatives available to Bayard. These
alternatives included the proposed sale of a new series of preferred stock to
Fund A, a possible stock-for-stock merger with Company A and a possible
stock-for-stock merger with Nabors. The Bayard Board believed that each of these
alternatives could enable Bayard to continue to implement its core business
strategy, although, in the case of a stock-for-stock merger, Bayard's operations
would be combined with those of another operator. After weighing the
alternatives, the Bayard Board determined that it might be in the best interests
of Bayard and its stockholders to pursue a
 
                                       20
<PAGE>   26
 
stock-for-stock merger with Nabors. Among other things, the Bayard Board noted
that there was a close strategic fit between Bayard and Nabors, especially in
view of the fact that both companies had a focus on technologically advanced
rigs capable of deep drilling applications. In addition, the Bayard Board
considered as positive strategic factors the strong financial condition of
Nabors, its low level of debt, the large size of its contract drilling fleet and
the fact that it conducts significant international operations. Accordingly, the
Bayard Board instructed Mr. Brown to engage in further negotiations with Nabors
with a view towards obtaining an offer on improved terms.
 
     In the afternoon of October 7, 1998, Mr. Brown spoke with Richard Stratton,
Vice Chairman of the Board of Nabors, regarding the terms of a possible
stock-for-stock merger with Nabors. Mr. Stratton stated that Nabors was
unwilling to offer an exchange ratio greater than 0.375 shares of Nabors common
stock. However, he indicated that Nabors would be willing to offer additional
cash consideration in an amount to be determined based in part on a joint
analysis to be undertaken regarding the amount of severance costs expected to be
incurred in connection with the integration of the operations of the two
companies. Mr. Brown responded that he would seek authority from the Bayard
Board to propose a transaction incorporating these financial terms.
 
     Later on October 7, 1998, Mr. Brown discussed the latest Nabors offer with
certain directors who indicated that the Bayard Board would be willing to
consider the proposal.
 
     Also on October 7, 1998, Bayard contacted DLJ to discuss engaging DLJ as
financial advisor for the purpose of rendering an opinion as to the fairness
from a financial point of view to the holders of the shares of Bayard common
stock of the consideration to be received by such holders in a business
combination with Nabors. Among other reasons, DLJ was contacted by Bayard
because it was familiar with Bayard's business, financial condition and results
of operations as a result of having acted as underwriter in the initial public
offering of Bayard common stock and as initial purchaser in the Bayard senior
notes offering.
 
     On October 9, 1998, Nabors delivered to Bayard an initial draft of the
definitive agreements governing the transaction proposed by Nabors, including
the merger agreement and the stock option agreement.
 
     On October 13, 1998, the Bayard Board held a meeting to discuss in detail
the terms and conditions of the transaction proposed by Nabors. At such meeting,
the Bayard Board received presentations from, and reviewed the terms of the
proposed transaction with, Bayard's management, counsel and financial advisors.
The Bayard Board authorized management of Bayard to continue negotiations with
Nabors and instructed management and counsel to seek certain changes to the
proposed terms of the transaction.
 
     On October 15, 1998, Bayard formally engaged DLJ to act as financial
advisor for the purposes of rendering an opinion to the Bayard Board as to the
fairness to the holders of shares of Bayard common stock of the merger
consideration from a financial point of view.
 
     Beginning on October 12, 1998, the legal advisors and management of Bayard
and Nabors began to discuss in detail the terms of the agreements governing the
proposed transaction. The parties met from October 14, 1998 through October 16,
1998 to negotiate the terms of the merger agreement and the stock option
agreement, and agreement was reached on the principal terms on October 16, 1998.
On October 17, 1998, counsel for Bayard and Nabors resolved the remaining open
issues and completed preparation of definitive agreements.
 
     On October 18, 1998, the Bayard Board met to consider the terms of the
proposed transaction, as revised in the course of negotiations during the prior
week. Under the revised transaction terms, each share of Bayard common stock was
to be converted into (a) 0.375 shares of Nabors common stock and (b) $0.30 in
cash. The amount of cash consideration reflected the joint analysis undertaken
by Bayard and Nabors regarding the amount of severance costs expected to be
incurred in connection with the integration of the operations of the two
companies. The Bayard Board reviewed and discussed, and received a presentation
from counsel regarding, the terms of the definitive agreements. In addition, the
Bayard Board received a presentation from DLJ explaining the bases of its
opinion that the merger consideration was fair
 
                                       21
<PAGE>   27
 
from a financial point of view to Bayard's stockholders. After discussion of
such presentations and information, the meeting was adjourned.
 
     The meeting of the Bayard Board was reconvened on October 19, 1998. At the
reconvened meeting, DLJ delivered its opinion to the Bayard Board to the effect
that, as of such date, based on the matters described in the opinion, the merger
consideration was fair to the stockholders of Bayard from a financial point of
view. After considering DLJ's opinion, the Bayard Board unanimously authorized
and approved the merger agreement and the stock option agreement, subject, in
the case of the merger agreement, to the adoption of such agreement by the
stockholders of Bayard.
 
     On October 22, 1998, Bayard and Nabors filed their respective Premerger
Notification and Report forms as required under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976. On November 20, 1998 the Antitrust Division of the
Department of Justice requested that Bayard and Nabors provide additional
information and documents regarding the competitive effects of the merger. In
response, Bayard and Nabors have provided additional information to, and engaged
in extensive discussions with, the Antitrust Division. As of the date that this
document was first mailed to the Bayard stockholders, the merger has not yet
received clearance from the Antitrust Division.
 
     The merger agreement, the stock option agreement and the stockholder
agreements were executed by the parties on October 19, 1998, and a joint press
release announcing the merger was issued by the parties on the same date.
 
     On January 15, 1999, an amendment to the merger agreement was executed by
the parties to eliminate Nabors' obligation to enter into an employment
agreement with Edward S. Jacob, III. Mr. Jacob was an executive officer of
Bayard before his employment terminated on January 15, 1999. In connection with
the amendment to the merger agreement, Nabors consented to the execution and
performance of a severance arrangement between Bayard and Mr. Jacob and waived
any breaches of the merger agreement that may result from that severance
arrangement.
 
     On February 9, 1999, Mr. Isenberg, Mr. Stratton and Anthony Petrello,
President and Chief Operating Officer of Nabors, contacted Mr. Brown and
informed him that Nabors was unwilling to proceed with the merger because, under
the terms of the merger agreement, Nabors believed it no longer had an
obligation to close. Mr. Isenberg, however, stated that Nabors would be willing
to proceed with the merger if Bayard were willing to accept a lower exchange
ratio.
 
     On February 9 and 10, 1999, Mr. Brown discussed the fact that Nabors was
unwilling to proceed with the transaction with certain members of the Bayard
Board. These directors generally indicated that they would support a modest
decrease in the exchange ratio, but would require additional assurances from
Nabors that it would proceed to consummate the merger.
 
     On February 10, 1999, Mr. Brown had various conversations with Mr. Isenberg
and Mr. Stratton in which possible exchange ratios were discussed. At the
conclusion of these discussions, Mr. Isenberg stated that Nabors would be
willing to offer an exchange ratio of 0.3375, with the cash portion of the
merger consideration to remain unchanged. Mr. Brown indicated that he would be
willing to propose these terms to the Bayard Board.
 
     On February 11, 1999, Bayard delivered to Nabors a draft of a second
amendment to the merger agreement. This draft incorporated the proposed
reduction of the exchange ratio to 0.3375 and sought certain assurances from
Nabors that it would proceed to consummate the merger. The terms of the second
amendment to the merger agreement were discussed and negotiated by Mr. Brown,
Mr. Petrello and Mr. Stratton during the afternoon and evening of February 11,
1999 and the morning of February 12, 1999.
 
     On February 12, 1999 the Bayard Board held a meeting to discuss the terms
of the proposed second amendment to the merger agreement. All members of the
Bayard Board were present at the meeting, except for Mark Liddell, who was not
available at the time. Representatives of DLJ and Bayard's counsel also attended
the meeting. Under the terms of the second amendment, the exchange ratio of
Bayard
 
                                       22
<PAGE>   28
 
common stock to Nabors commons stock was to be reduced to 0.3375. In addition,
the second amendment contemplated that:
 
     - the definition of the term "material adverse effect" would be limited so
       as to exclude actual or anticipated events that were known by or
       disclosed to a party before or on the date of the amendment;
 
     - the termination fee payable by Nabors in the event the merger agreement
       were terminated due to a breach of any covenant or agreement or material
       representation or warranty by Nabors would be increased to $15.0 million;
       and
 
     - the date upon which the merger agreement would become terminable by
       either party would be extended from May 1, 1999 to September 30, 1999.
 
At the meeting, the Bayard Board received a presentation from DLJ regarding the
bases of its updated opinion that the merger consideration, as modified by the
second amendment, was fair to Bayard's stockholders from a financial point of
view. The Bayard Board also received a presentation from counsel regarding
Bayard's legal options and rights under the merger agreement as then in effect
and the terms of the proposed second amendment. After a discussion of the
matters covered by these presentations, DLJ delivered its opinion to the effect
that, as of February 12, 1999, based on the matters described in the opinion,
the merger consideration, as modified by the second amendment, was fair to the
stockholders of Bayard from a financial point of view. After considering DLJ's
opinion, the Bayard Board determined by a unanimous vote of the directors
present at the meeting that the merger agreement, as amended by the second
amendment, was advisable and in the best interests of, and was fair to, the
stockholders of Bayard. The Bayard Board then authorized and approved the second
amendment to the merger agreement, and recommended by a unanimous vote of the
members present at the meeting that the stockholders of Bayard vote FOR the
adoption of the merger agreement, as amended. This approval was subsequently
ratified by the entire Bayard Board, including Mr. Liddell, in a unanimous
written consent dated February 12, 1999.
 
     The second amendment to the merger agreement was executed by the parties
following the meeting of the Bayard Board on February 12, 1999, and a joint
press release announcing the new terms was issued by Bayard and Nabors on the
same date.
 
REASONS FOR THE MERGER
 
     Bayard's primary reason for seeking to consummate a business combination
with Nabors is the belief of the Bayard Board and management that the
combination of the resources and operations of Bayard and Nabors is a good
strategic fit, especially in view of the fact that both companies have a focus
on technologically advanced rigs capable of deep drilling applications. In
addition, the Bayard Board considered as positive strategic factors the strong
financial condition of Nabors, its low level of debt, the large size of its
contract drilling fleet and the fact that it conducts significant international
operations. Accordingly, the Bayard Board concluded that Nabors, after giving
effect to the acquisition of Bayard in the merger, is likely to be a stronger
competitor in the short-term and long-term than either Nabors or Bayard as an
independent company.
 
     In determining that the merger agreement, the stock option agreement and
the merger and the other transactions contemplated by such agreements, taken
together, are advisable and in the best interests of, and are fair to, the
stockholders of Bayard, the Bayard Board considered a number of factors,
including the following:
 
     - the strategic courses of action which Bayard might have elected to pursue
       instead of the merger, which were rejected by the Bayard Board for the
       reasons described in detail under "-- Background of the Merger" above;
 
     - the information obtained by the Bayard Board in the course of
       presentations by Bayard's management regarding the business, financial
       condition and results of operations of Bayard and
 
                                       23
<PAGE>   29
 
       Nabors, including information as to the short-term and long-term effects
       of adverse conditions in the domestic land drilling industry;
 
     - the knowledge of the members of the Bayard Board of the risks and
       uncertainties associated with a decision to continue to operate Bayard as
       an independent company, including, but not limited to, the risks
       associated with cyclical market conditions in the domestic land drilling
       industry and the degree of leverage to which Bayard had become subject as
       a result of its senior notes offering;
 
     - the belief of the Bayard Board and management that increased revenue
       development opportunities, economies of scale and other cost savings
       obtainable from the combination would, if realized, create additional
       value for the former stockholders of Bayard;
 
     - the opinion of DLJ to the effect that the merger consideration to be
       received by the stockholders of Bayard in the merger was fair to such
       holders from a financial point of view;
 
     - the belief of the Bayard Board that the capital structure of Nabors after
       the merger would afford sufficient flexibility to enable Nabors to pursue
       its business strategy without being subject to the limitations associated
       with a substantial degree of leverage;
 
     - the fact that the Bayard stockholders would obtain in the merger an
       equity investment in Nabors on a tax-free basis;
 
     - the fact that, as stockholders of Nabors, the former stockholders of
       Bayard would not be foreclosed from participating in any control premium
       that may be realized in connection with any future transactions involving
       a sale or change of control of Nabors;
 
     - the fact that James E. Brown, a member of the Bayard Board, had financial
       incentives to support the merger that were in addition to and different
       from those of the other directors and stockholders of Bayard as a result
       of the employment agreement proposed to be entered into between Nabors
       and Mr. Brown, as described below under "-- Interests of Certain Persons
       in the Merger;"
 
     - the fact that the consenting stockholders were willing to enter into the
       stockholder agreements in order to induce Nabors to enter into the merger
       agreement;
 
     - the fact that the merger agreement is structured in such a way as to
       permit Bayard, subject to certain procedures and limitations, to disclose
       nonpublic information to, and to engage in discussions and negotiations
       with, third parties who have made bona fide, unsolicited, written
       proposals with respect to competing acquisition transactions if the
       fiduciary duties of the Bayard Board so require; and
 
     - the fact that the merger agreement, subject to certain procedures and
       limitations, gives Bayard the right to terminate such agreement if the
       fiduciary duties of the Bayard Board so require in connection with a
       competing acquisition proposal, together with the fact that the ability
       of Bayard to do so is affected by the termination fee provisions of the
       merger agreement and the provisions of the stock option agreement, which
       could have the effect of deterring a competing acquisition proposal, and
       the belief of the Bayard Board that it was necessary to accept these
       provisions in order to obtain other terms, principally the favorable
       exchange ratio at which Bayard common stock is to be converted into
       Nabors common stock, from Nabors.
 
     In view of the variety of factors considered, the Bayard Board did not find
it practicable to, and did not, quantify or otherwise attempt to assign specific
or relative weights to the factors considered in making its determination. In
addition, individual members of the Bayard Board may have given different
weights to different factors.
 
RECOMMENDATION OF THE BAYARD BOARD
 
     FOR THE REASONS DISCUSSED ABOVE, THE BAYARD BOARD UNANIMOUSLY RECOMMENDS
THAT THE STOCKHOLDERS OF BAYARD VOTE FOR ADOPTION OF THE MERGER AGREEMENT.

OPINION OF BAYARD'S FINANCIAL ADVISOR
 
     DLJ was engaged by Bayard to render a written opinion to the Bayard Board
as to the fairness to the stockholders of Bayard, from a financial point of
view, of the merger consideration to be received by the holders of Bayard common
stock. On February 12, 1999, DLJ delivered an oral opinion to the Bayard Board
to the effect that, as of such date, the merger consideration was fair to the
holders of Bayard common stock from a financial point of view. DLJ also
delivered to the Bayard Board a written opinion, dated February 12, 1999, to the
effect that, as of such date and based upon and subject to the assumptions,
limitations and qualifications set forth in the opinion, the merger
consideration was fair to the holders of Bayard common stock from a financial
point of view.
 
     THE FULL TEXT OF THE WRITTEN OPINION OF DLJ, WHICH SETS FORTH THE
ASSUMPTIONS MADE, MATTERS CONSIDERED AND LIMITATIONS ON THE REVIEW UNDERTAKEN IN
CONNECTION WITH THE OPINION, IS ATTACHED TO THIS DOCUMENT AS ANNEX B. BAYARD
STOCKHOLDERS ARE URGED TO, AND SHOULD, READ THE OPINION IN ITS ENTIRETY FOR THE
ASSUMPTIONS MADE, PROCEDURES FOLLOWED, OTHER MATTERS CONSIDERED AND LIMITS OF
THE REVIEW OF DLJ.
 
     The opinion was prepared for the Bayard Board and is directed only to the
fairness of the merger consideration to be received by the holders of Bayard
common stock from a financial point of view and does not constitute a
recommendation to any Bayard stockholder as to how such stockholder should vote
at the special meeting.
 
     The written opinion prepared for the Bayard Board does not constitute an
opinion as to the fairness of any terms of the merger agreement, the stockholder
agreements or the stock option agreement other than the fairness of the merger
consideration to be received by the holders of Bayard common stock. Similarly,
DLJ's opinion does not constitute an opinion as to the price at which Nabors
common stock will actually trade at any time. The merger consideration was
determined through arm's-length negotiations between Bayard and Nabors.
 
     In arriving at its opinion, DLJ reviewed drafts of the amended merger
agreement, the stockholder agreements and the stock option agreement. DLJ also
reviewed financial and other information that was publicly available or
furnished to DLJ by Bayard and Nabors, including information provided during
discussions with their respective managements. DLJ was also provided with
certain financial projections of Bayard for the period beginning January 1, 1998
and ending December 31, 2002. In addition, DLJ compared certain financial and
securities data of Bayard and Nabors with various other companies whose
securities are traded in public markets, reviewed the historical stock prices
and trading volumes of Bayard common stock and Nabors common stock, reviewed
prices and premiums paid in certain other business combinations and conducted
such other financial studies, analyses and investigations as DLJ deemed
appropriate for purposes of the opinion. DLJ was not requested to, nor did DLJ,
solicit the interest of any other party in acquiring Bayard.
 
     In rendering its opinion, DLJ relied upon and assumed the accuracy and
completeness of all of the financial and other information that was available to
it from public sources and that was provided to DLJ by Bayard and Nabors or
their respective representatives. In particular, DLJ relied upon the estimates
of management of Bayard and Nabors of the operating synergies achievable as a
result of the merger and its discussion of such synergies with the management of
Nabors. With respect to the financial projections supplied to DLJ, DLJ assumed
that such projections were reasonably prepared on the basis reflecting the best
currently available estimates and judgments of the management of Bayard as to
the future operating and financial performance of Bayard. DLJ did not assume any
responsibility for making an independent evaluation of Bayard's and Nabors'
assets or liabilities or for making any independent verification of any of the
information reviewed by DLJ.
 
     The opinion is necessarily based on economic, market, financial and other
conditions as they existed on, and on the information made available to DLJ as
of, February 12, 1999.
 
     Set forth below is a summary of the material analyses performed by DLJ in
connection with the preparation of its opinion and included in the presentation
made by DLJ to the Bayard Board on February 12, 1999. With regard to the
calculation of implied per share values of Bayard common stock in
                                       25
<PAGE>   31
 
the following analyses, certain results were determined to be "not meaningful"
or "NM" because, in certain periods, estimated results for Bayard included a net
loss or negative "After-Tax Cash Flow," as defined below. Additionally, in
certain periods, Bayard's net debt was greater than certain multiple values of
estimated EBITDA. Therefore, values implied for Bayard common stock in those
periods are negative and not meaningful. The following table sets forth the
results of certain of these analyses, which should be considered together with
the more detailed information set forth below.

     Analysis of Certain Other Publicly Traded Companies. To provide contextual
data and comparative market information, DLJ compared selected share price,
earnings and operating and financial ratios for Bayard to the corresponding data
and ratios of certain other companies whose securities are publicly traded.
Although no company used in the comparable company analysis is identical to
Bayard, DLJ believes the selected companies to be appropriate comparisons to
Bayard because of similar operating characteristics, size or geographical focus
believed to be comparable to such characteristics of Bayard. These selected
companies included: Grey Wolf Inc., Nabors, Parker Drilling Company, Patterson
Energy Inc., Pride International Inc. and UTI Energy Corp.
 
     Such data and ratios included measures of value defined by market
capitalization of common stock plus total debt assumed less cash and cash
equivalents of the comparable companies ("Enterprise Value") as a multiple of
the last twelve-month reporting period before the announcement ("LTM"), earnings
before interest, taxes and depreciation and amortization ("EBITDA"), 1998
estimated EBITDA, 1999 estimated EBITDA and 2000 estimated EBITDA. In addition,
ratios included equity value as a multiple of LTM net income plus deferred
taxes, depreciation and amortization ("After-Tax Cash Flow"), 1998 estimated
After-Tax Cash Flow, 1999 estimated After-Tax Cash Flow and 2000 estimated
After-Tax Cash Flow. The comparable company analysis was conducted based upon
closing prices on February 11, 1999.
 
     Based upon an exchange ratio of 0.3375 Nabors shares and $0.30 cash per
share of Bayard common stock at Nabors' February 11, 1999 closing price of
$12.19, the implied per share transaction value to Bayard was $4.41 per share.
 
     DLJ examined the adjusted mean multiple of Enterprise Value to 1998
estimated EBITDA, 1999 estimated EBITDA and 2000 estimated EBITDA for the
comparable companies which were 5.6x, 7.1x and 5.0x, respectively. These
multiples implied valuations of Bayard common stock per share which were NM in
the first two cases and $1.54 in the third. The maximum and minimum values for
comparable company Enterprise Value multiples were 9.5x and 3.4x for 1998
estimated EBITDA, 9.7x and 5.7x for 1999 estimated EBITDA and 8.0x and 3.3x for
2000 estimated EBITDA. This compares with implied Enterprise Value multiples of
1998 estimated EBITDA, 1999 estimated EBITDA and 2000 estimated EBITDA for
Bayard based upon the proposed merger consideration of 15.1x, 21.9x and 6.8x,
respectively.
 
     DLJ also examined the adjusted mean multiple of equity value to 1998
estimated After-Tax Cash Flow, 1999 estimated After-Tax Cash Flow and 2000
estimated After-Tax Cash Flow for the comparable companies which were 4.0x, 6.3x
and 3.8x, respectively. These multiples implied Bayard per share values of
$1.87, NM and $3.85, respectively. The maximum and minimum values for comparable
company equity value multiples were 7.1x and 1.8x for 1998 estimated After-Tax
Cash Flow, 8.1x and 2.3x for 1999 estimated After-Tax Cash Flow and 5.7x and
1.7x for 2000 estimated After-Tax Cash Flow. This compares with implied equity
value multiples of 1998 estimated After-Tax Cash Flow, 1999 estimated After-Tax
Cash Flow and 2000 estimated After-Tax Cash Flow for Bayard based upon the
proposed merger consideration of 9.3x, NM and 4.4x, respectively.

     DLJ's analysis of certain other publicly traded companies is summarized in
the following table:

  2000 Estimated After-Tax Cash Flow.....   5.7x       3.8x      1.7x          $3.85
</TABLE>
 
     The Bayard per share value range implied by this analysis was $1.54 to
$3.85. Because $4.41, the implied per share transaction value to Bayard from the
merger, was above this range, this analysis supported DLJ's opinion.
 
     Transaction Analysis. DLJ reviewed publicly available information for a
number of selected transactions involving the combination of contract drilling
companies completed since November 1996. The transactions selected were not
intended to represent a complete list of contract drilling transactions which
have occurred during the last three years; rather they included transactions
involving combinations of companies with operating characteristics, size or
geographical focus believed to be comparable to such characteristics of Bayard.
These selected transactions include: Nabors/Pool Energy Services; Key Energy
Group/Dawson Production Services; R&B Falcon Corporation/Cliffs Drilling
Company; Parker Drilling Company/Hercules Offshore; Bayard/Bonray Drilling
Corporation; Pride Petroleum Services/Forasol-Foramer; Dawson Production
Services/Pride Petroleum Services; and Parker Drilling Company/Mallard Bay
Drilling. Although these transactions were used for comparison purposes, none of
such transactions is directly comparable to the merger. An analysis of
comparable transactions is not purely mathematical, rather it involves complex
considerations and judgments concerning similarities and differences in
financial, operational and other characteristics of potentially comparable
transactions.
 
     DLJ reviewed the consideration paid in such comparable transactions in
terms of the Enterprise Value in such transactions as a multiple of LTM and
estimated forward fiscal year EBITDA. The adjusted mean multiple of Enterprise
Value to LTM EBITDA was 10.8x with a high of 30.1x and a low of 4.4x. The
adjusted mean multiple of Enterprise Value to estimated forward fiscal year
EBITDA was 7.0x with a high of 12.0x and a low of 4.2x. Based upon these
adjusted mean multiples, the implied valuation of Bayard common stock per share
was $5.18 and NM, respectively.
 
     DLJ also reviewed the consideration paid in such transactions in terms of
the equity value in such transactions as a multiple of LTM After-Tax Cash Flow
and estimated forward fiscal year After-Tax Cash Flow. The adjusted mean
multiple of equity value to LTM After-Tax Cash Flow was 13.8x with a high of
32.5x and a low of 4.1x. The adjusted mean multiple of equity value to estimated
forward fiscal year After-Tax Cash Flow was 5.7x with a high of 16.3x and a low
of 4.2x. Based upon these adjusted mean multiples, the implied value range of
Bayard common stock per share was $9.92 to $2.69.
 
     DLJ's transaction analysis is summarized in the following table:

<PAGE>   33
 
     The Bayard per share value range implied by this analysis was $2.69 to
$9.92. Because $4.41, the implied per share transaction value to Bayard from the
merger, was within this range, this analysis supported DLJ's opinion.
 
     Discounted Cash Flow Analysis. DLJ also performed a discounted cash flow
analysis of Bayard using Bayard's projections.
 
     DLJ calculated the discounted present value of future net cash flows
attributable to contract drilling operations by applying various assumptions
regarding capital expenditures, sales and direct costs. Terminal values in the
year 2003 were assumed in three separate cases to be multiples of After-Tax Cash
Flow of 4.0x, 5.0x and 6.0x, based upon analysis of historical industry
valuations. Finally, these net cash flows were discounted back to present value
based upon a range of discount factors utilizing the Capital Asset Pricing
Model.
 
     DLJ calculated equity values ranging from a low of $60.3 million to a high
of $100.5 million, based upon the discounted cash flow analysis. With 18.3
million fully diluted shares of Bayard common stock outstanding, the implied
values of Bayard common stock per share ranged from $3.31 to $5.52.
 
     Because $4.41, the implied per share transaction value to Bayard from the
merger, was within this range, the discounted cash flow analysis supported DLJ's
opinion.
 
     Pro Forma Merger Analysis. DLJ also performed a pro forma merger analysis
to determine the impact of the merger on Nabors' net income per share ("EPS")
and After-Tax Cash Flow per share. DLJ performed the analysis for each of the
three years ended December 31, 1998 through 2000 as if the merger had been
completed on January 1 of each year. Based upon this pro forma analysis, DLJ
determined that the merger was dilutive to After-Tax Cash Flow per share in both
1998 and 1999 by approximately 1.6% and 5.1%, respectively, and accretive to
After-Tax Cash Flow per share in 2000 by 1.7%. The analysis determined that the
merger was dilutive to EPS in 1998 and 1999 by approximately 5.0% and 13.4%,
respectively, and accretive to EPS in 2000 by 1.6%. DLJ included synergies equal
to $2 million per year in its analysis.
 
     Because the analysis assumed that Bayard would produce negative net income
and cash flow in 1999, the transaction was dilutive to Nabors and, conversely,
accretive to Bayard in those periods. However, in 2000, the first actual full
year of the merger and a year in which the projections assume an improvement in
the business, the transaction was slightly accretive to Nabors. Based upon this
analysis, the pro forma merger analysis support DLJ's opinion.
 
     Relative Contribution Analysis. In addition, DLJ conducted a relative
contribution analysis of Bayard's LTM and projected operating performance with
respect to the combined company.
 
     The relative contribution of each of Bayard and Nabors to the combined
company of certain financial measures were reviewed, including EBITDA, net
income and After-Tax Cash Flow and compared with the amount of common equity,
5.7%, being distributed to Bayard's stockholders in the merger.
 
     Bayard's contribution of LTM EBITDA, 1998 estimated EBITDA, 1999 estimated
EBITDA and 2000 estimated EBITDA was 6.1%, 4.6%, 3.8% and 8.2%, respectively.
Bayard's contribution of LTM net income, 1998 estimated net income, 1999
estimated net income and 2000 estimated net income was 1.2%, NM, NM and 1.3%,
respectively. Finally, Bayard's contribution of LTM After-Tax Cash Flow, 1998
estimated After-Tax Cash Flow, 1999 estimated After-Tax Cash Flow and 2000
estimated After-Tax Cash Flow was 4.6%, 3.9%, NM and 6.6%, respectively.
 
     Because the relative contribution by Bayard in each of these measures
ranged from 1.2% to 8.2% and the amount of common equity being distributed to
Bayard's stockholders in the merger was 5.7%, the relative contribution analysis
supported DLJ's opinion.
 
     The summary set forth above does not purport to be a complete description
of the analyses performed by DLJ in connection with the preparation of its
opinion. The preparation of a fairness opinion involves various determinations
as to the most appropriate and relevant methods of financial analysis and the
 
                                       28

application of these methods to the particular circumstances and, therefore,
such an opinion is not readily susceptible to summary description. Each of the
analyses conducted by DLJ was carried out in order to provide a different
perspective on the transaction and add to the total mix of information
available. DLJ did not form a conclusion as to whether any individual analysis,
considered in isolation, supported or failed to support an opinion as to
fairness from a financial point of view. Rather, in reaching its conclusion, DLJ
considered the results of the analyses in light of each other and ultimately
reached its opinion based on the results of all analyses taken as a whole. DLJ
did not place particular reliance or weight on any individual analysis, but
instead concluded that its analyses, taken as a whole, supported its
determination. Accordingly, DLJ believes that its analyses must be considered as
a whole and that selecting portions of its analysis and the factors considered
by it, without considering all analyses and factors, could create an incomplete
view of the evaluation process underlying the opinion. The analyses performed by
DLJ are not necessarily indicative of actual values of future results, which may
be significantly more or less favorable than suggested by such analyses.
 
     Under the terms of an engagement letter dated October 15, 1998, Bayard
agreed to pay DLJ $500,000, payable in cash, for rendering the fairness opinion.
Bayard also agreed to reimburse DLJ promptly for certain out-of-pocket expenses,
including reasonable fees and out-of-pocket expenses of counsel, incurred by DLJ
in connection with its engagement, and to indemnify DLJ and certain related
persons against certain liabilities in connection with its engagement, including
liabilities under the federal securities laws. The terms of the fee arrangement
with DLJ, which DLJ and Bayard believe are customary in transactions of this
nature, were negotiated at arm's length between Bayard and DLJ and the Bayard
Board was aware of such arrangement. DLJ has been engaged to perform investment
banking services for Bayard in the past and has been compensated for such
services. Those services have included acting as lead managing underwriter for
the initial public offering of Bayard common stock in November 1997. DLJ and
Bayard are currently involved in class action litigation relating to such
offering. In addition, DLJ was the initial purchaser in Bayard's senior notes
offering in June 1998 and advised Bayard with respect to the adoption of the
Bayard rights agreement in August 1998.
 
     The Bayard Board selected DLJ as its financial advisor because it is a
nationally recognized investment banking firm and the principals of DLJ have
substantial experience in transactions similar to the merger and are familiar
with Bayard and its business. In the ordinary course of business, DLJ may trade
the securities of both Bayard and Nabors for its own account and for the
accounts of its customers and, accordingly, may at any time hold a long or short
position in such securities. DLJ, as part of its investment banking services, is
regularly engaged in the valuation of businesses and securities in connection
with mergers, acquisitions, underwritings, sales and distributions of listed and
unlisted securities, private placements and valuations for corporate and other
purposes.
 
EFFECTIVE TIME
 
     Subject to the terms and conditions of the merger agreement, the closing of
the merger will occur on the first business day immediately following the day on
which the conditions to closing set forth in the merger agreement are fulfilled
or waived unless Bayard and Nabors agree otherwise. It is anticipated that the
last of the conditions to the closing to be fulfilled will be either the
expiration or termination of the waiting period under the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended, or the adoption of the merger
agreement by the Bayard stockholders. Promptly after such conditions are
fulfilled, a certificate of merger relating to the merger will be filed with the
Delaware Secretary of State. The time when the certificate of merger is filed,
or such later time as is specified in the certificate of merger, is referred to
as the "effective time" of the merger.
 
EXCHANGE OF CERTIFICATES
 
     As of the effective time, Nabors will deposit with an exchange agent
certificates representing the aggregate whole number of shares of Nabors common
stock to be issued in the merger and cash in an amount equal to the aggregate
cash portion of the merger consideration plus the estimated amount to be paid
instead of fractional shares of Nabors common stock. As soon as is reasonably
practicable after the
                                       29
<PAGE>   35
 
effective time, Nabors will instruct the exchange agent to mail to each holder
of record of certificates formerly representing Bayard common stock transmittal
materials for use in exchanging such Bayard certificates for certificates
representing shares of Nabors common stock, the cash portion of the merger
consideration and, if applicable, cash instead of a fractional share of Nabors
common stock.
 
     STOCKHOLDERS SHOULD NOT SEND IN THEIR STOCK CERTIFICATES UNTIL THEY RECEIVE
A TRANSMITTAL FORM.
 
FEDERAL SECURITIES LAW CONSEQUENCES
 
     The shares of Nabors common stock to be issued to the former stockholders
of Bayard in the merger have been registered under the Securities Act of 1933.
Accordingly, all such shares of Nabors common stock will be freely transferable
under the Securities Act of 1933, except that shares of Nabors common stock
received by persons who are deemed to be "affiliates," as such term is defined
under the Securities Act of 1933, of Bayard before the merger or who become
"affiliates" of Nabors after the merger may be resold by them only in
transactions permitted by the resale provisions of Rule 145 promulgated under
the Securities Act of 1933 or as otherwise permitted under the Securities Act of
1933. Rule 145 generally provides that "affiliates" of an acquired company may
not sell securities of the issuer unless the securities are sold:
 
     - in accordance with the volume, manner of sale and public information
       requirements of Rule 144; or
 
     - without regard to the volume or manner of sale requirements of Rule 144,
       but subject to its public information requirements, if the persons do not
       become "affiliates" of the acquiror after the merger and have held the
       shares acquired in the merger for at least one year.
 
Rule 144 generally requires that the quantity of shares sold in any three-month
period not exceed the greater of 1% of the outstanding shares of the issuer or
the average weekly reported volume of trading in such shares for the four weeks
preceding the notice of sale. Rule 144 also requires that such sales be made in
unsolicited, open market "brokers' transactions." Persons who may be deemed to
be "affiliates" of Nabors or Bayard generally include individuals or entities
that control, are controlled by, or are under common control with, such party
and may include certain officers and directors of such party as well as
principal stockholders of such party. The merger agreement requires Bayard to
use its best efforts to obtain from each of its "affiliates" a written agreement
to the effect that such person will not sell, transfer or otherwise dispose of
any of the shares of Nabors common stock issued to such person in the merger in
violation of the Securities Act of 1933 or the rules and regulations promulgated
by the Commission. Bayard estimates that approximately 1,000,000 shares of
Nabors common stock will be affected by these restrictions.
 
     Nabors has agreed in the merger agreement that, before the merger, it will
enter into an agreement with those persons who will receive shares of Nabors
common stock in the merger which will be subject to the resale restrictions of
Rule 144 and Rule 145 under the Securities Act of 1933. In such agreement,
Nabors will be required to grant to such persons the right to demand a single
registration under the Securities Act of 1933 of not less than 1,000,000 shares
of Nabors common stock received by them in the merger.
 
AMERICAN STOCK EXCHANGE LISTING OF NABORS COMMON STOCK
 
     In the merger agreement, Nabors has agreed to use its best efforts to cause
the shares of Nabors common stock to be issued in the merger to be approved for
listing on AMEX before the merger. The obligations of Bayard, Nabors and Nabors'
acquisition subsidiary to close the merger are conditioned upon, among other
things, such shares of Nabors common stock being listed on AMEX.
 
CERTAIN EFFECTS OF THE MERGER
 
     If the merger is consummated, Bayard will become a wholly owned subsidiary
of Nabors. As a result, public trading of the shares of Bayard common stock will
cease, the shares of Bayard common stock will
 
                                       30
<PAGE>   36
 
cease to be listed and traded on AMEX and the registration of the shares of
Bayard common stock under the Securities Exchange Act of 1934 will be
terminated.
 
     For information concerning the federal income tax consequences of the
merger, see "Federal Income Tax Consequences."
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
     In considering the recommendation of the Bayard Board with respect to the
merger, Bayard stockholders should be aware that certain of the directors and
executive officers of Bayard have the following interests in the merger that
differ from, or are in addition to, the interests of the stockholders of Bayard
generally.
 
  Employment Agreement with Bayard Executive
 
     In the merger agreement, Nabors has agreed to cause Nabors Drilling USA,
Inc., a wholly owned subsidiary of Nabors, to enter into an employment agreement
with James E. Brown, the Chairman of the Board, President and Chief Executive
Officer of Bayard. The Brown employment agreement with NDUSA will replace, and
cause the termination of, the employment agreement previously entered into
between Bayard and Mr. Brown.
 
     The Brown employment agreement provides for a two-year term of employment
beginning on the date of the merger. Following the initial two-year term, the
agreement is subject to renewal upon the mutual agreement of Mr. Brown and
NDUSA. Mr. Brown will be elected initially as Vice President -- Central Division
of NDUSA and will receive base annual cash compensation of $175,000 and an
annual bonus determinable at the discretion of the board of directors of NDUSA.
Mr. Brown will be entitled to the use of a company-owned vehicle or an $800 per
month automobile allowance as well as paid vacation and will be eligible to
participate in all benefit programs provided by NDUSA in accordance with their
terms. In consideration of Mr. Brown's agreement to waive his rights under his
prior employment agreement with Bayard, Mr. Brown will also receive a lump sum
signing bonus of $300,000. Mr. Brown will receive options to acquire 200,000
shares of Nabors common stock, exercisable at the closing price for Nabors
common stock on the date of commencement of employment. Such options will vest
annually in four equal installments beginning on the first anniversary of the
date of grant, will have a ten-year term and will be subject to the terms of
Nabors' standard form stock option agreement and the applicable stock option
plan.
 
     The Brown employment agreement provides that NDUSA may terminate Mr. Brown
for any of the following reasons:
 
     - Mr. Brown's death;
 
     - total or partial disability of Mr. Brown which renders him permanently
       unable to perform his duties;
 
     - total or partial disability of Mr. Brown which renders him temporarily
       unable to perform his duties for a period of 180 consecutive days;
 
     - "cause," which is defined in the Brown employment agreement to include
       such acts as fraud, theft, felony conviction or willful or repeated
       failure to perform the duties of his employment in any material respect;
       or
 
     - any reason, without cause, upon 30 days' prior written notice.
 
Mr. Brown may voluntarily terminate his employment at any time upon 30 days'
prior written notice. If NDUSA terminates Mr. Brown's employment for any of the
first three reasons noted above, NDUSA will be required to pay Mr. Brown's base
salary for six months or the time remaining in the term of employment, whichever
is less. If NDUSA terminates Mr. Brown for cause, no further unaccrued payment
 
                                       31
<PAGE>   37
 
will be made. If NDUSA terminates Mr. Brown without cause, he will be entitled
to receive his base salary for the time remaining in the term of employment.
 
     Mr. Brown has agreed that for the period of time that NDUSA is making
payments as required under the respective employment agreement, he will not
engage in any business that is also conducted by NDUSA or its affiliates, or,
subject to certain limitations, own or become employed by a business that
competes with NDUSA or its affiliates in any geographic area in which NDUSA or
its affiliates has significant business activities, including but not limited to
the continental United States and Mexico. During that period, Mr. Brown is
prohibited from interfering with the customer and employee relationships of
NDUSA and its affiliates.
 
  Transactions between Nabors and National Oilwell, L.P.
 
     Merrill A. Miller, Jr., a director of Bayard, is Vice President of National
Oilwell, L.P., an oilfield services company, and President of its Products &
Technology Group. National Oilwell, L.P. is a significant supplier to Nabors,
providing Nabors with construction services and various related products and
equipment. National Oilwell, L.P. has advised Bayard that Nabors is one of its
top ten customers in terms of revenue.
 
  Options
 
     As shown in the following table, Bayard officers and directors hold options
to purchase a total of 770,000 shares of Bayard common stock, of which 199,835
were exercisable as of, or will become exercisable within 60 days after, January
15, 1999.

     The merger agreement provides that each outstanding option to purchase
Bayard common stock will be converted into an option to purchase Nabors common
stock. Each converted option will be exercisable for that number of whole shares
of Nabors common stock equal to the product of the number of shares of Bayard
common stock covered by such option immediately before the merger multiplied by
0.3375, rounded up to the nearest whole number of shares of Nabors common stock.
The per share exercise price for the shares of Nabors common stock issuable upon
the exercise of such Nabors stock option will be an amount determined by
dividing (i) the amount obtained by subtracting (a) $0.30 from (b) the exercise
price per share of Bayard common stock for such Bayard stock option, by (ii)
0.3375 and rounding the resulting exercise price up to the nearest whole cent.
The Nabors stock options granted upon conversion of Bayard stock options
outstanding immediately before the merger will have the same schedule of vesting
and same period for exercise as applies to such Bayard stock options. However,
Nabors stock options received upon such conversion by employees of Bayard who
are terminated by the surviving corporation without cause during the one-year
period immediately following the merger will immediately and fully vest upon
such termination.

  Warrants
 
     Energy Spectrum Partners LP and Wil-Cas Investments, L.P. hold warrants for
the purchase of 112,000 and 169,400 shares of Bayard common stock, respectively.
Sidney L. Tassin, a director of Bayard, is also the President and a member of
Energy Spectrum LLC, which is the ultimate general partner of Energy Spectrum
Partners LP. Lew O. Ward, a director of Bayard, is an officer and director of
Ward Petroleum Corporation. Wil-Cas Investments, L.P. is controlled by Ward
Petroleum Corporation and family trusts for the benefit of Mr. Ward's children.
The merger agreement provides that all outstanding warrants for the purchase of
Bayard common stock, including the warrants held by Energy Spectrum Partners LP
and Wil-Cas Investments, L.P., will remain outstanding on the same terms as in
effect immediately before the merger. After the merger, the warrants will be
exercisable for:
 
     - a number of whole shares of Nabors common stock equal to the product of
       the number of shares of Bayard common stock covered by the warrant
       multiplied by 0.3375, rounded up to the nearest whole number of shares of
       Nabors common stock; and
 
     - an amount of cash equal to the product of the number of shares of Bayard
       common stock covered by the warrant multiplied by $0.30.
 
  Severance Arrangements; Continuing Employment Agreement
 
     The merger agreement provides that, under certain circumstances, Nabors
will make cash severance payments to certain identified employees of Bayard,
including David E. Grose, III, the Vice President and Chief Financial Officer of
Bayard. Nabors will incur these severance obligations if the applicable
employees remain employed by Bayard immediately before the merger and Nabors
terminates their employment within one year after the merger. Any such payments
would be made instead of amounts otherwise payable by Bayard under any other
severance agreement.
 
     In the case of Mr. Grose, Nabors would pay $105,000 in cash to Mr. Grose if
it terminates his employment within one year after the merger and if Mr. Grose
waives the right to severance payments under his existing employment agreement.
This employment agreement, dated as of July 16, 1997, entitles Mr. Grose to
continue to receive his base salary and other employee benefits through the
remaining term of the agreement and to receive a cash payment in an amount equal
to any earned but unpaid quarterly bonus for the previous quarter if, as a
result of a change of control, Mr. Grose is terminated without due cause or if
Mr. Grose elects to terminate his employment for any reason. The merger would
constitute a "change of control." Mr. Grose's base salary is currently $105,000.
The Grose employment agreement expires by its terms on June 30, 1999.
 
  Indemnification and Insurance
 
     The Restated Certificate of Incorporation and Amended and Restated Bylaws
of Bayard currently provide for indemnification of directors to the fullest
extent permitted by Delaware law. Nabors has agreed that the Restated
Certificate of Incorporation and Bylaws of the surviving corporation in the
merger will contain the indemnification provisions currently set forth in
Bayard's Certificate of Incorporation and Bylaws and that such provisions will
not be amended, repealed or otherwise modified for a period of six years after
the merger in any manner that would adversely affect the rights of individuals
under Bayard's Certificate of Incorporation or Bylaws who at any time before the
merger were directors or officers of Bayard in respect of actions or omissions
occurring at or before the merger, including, without limitation, the
transactions contemplated by the merger agreement, unless such modification is
required by law.
 
     In addition, from and after the merger, Nabors has agreed that it and the
surviving corporation will jointly and severally indemnify, defend and hold
harmless the present and former officers and directors of Bayard or any of its
subsidiaries against all losses, expenses, claims, damages or amounts paid in
settlement of, or otherwise in connection with, any threatened or actual claim,
action, suit, proceeding or investigation, based in whole or in part on the fact
that such person is or was a director or officer of Bayard or any of its
subsidiaries. This indemnification covers claims arising out of actions or
omissions
 
                                       33
<PAGE>   39
 
occurring at or before the merger and includes, but is not limited to, the
transactions contemplated by the merger agreement. In each case, the
indemnification will apply to the full extent permitted under Delaware law, and
Nabors will pay expenses, including fees and disbursements of counsel, as
incurred, in advance of the final disposition of any such action or proceeding
to each indemnified party upon receipt from the indemnified party to whom
expenses are advanced of an undertaking to repay such advances, as contemplated
by Delaware law.
 
     Under the terms of the merger agreement, commencing at the merger, the
directors and officers of the surviving corporation will be insured under the
policies of directors and officers insurance currently maintained by Nabors or
maintained by Nabors after the merger. In addition, for a period of four years
after the merger, Nabors will cause to be maintained in effect the current
policies of directors' and officers' liability insurance maintained by Bayard
and its subsidiaries, or equivalent policies, with respect to claims arising
from facts or events which occurred before the merger; provided that Nabors will
not be required to pay an annual premium for such insurance in excess of two
times the last annual premium paid by Bayard before the date of the merger
agreement, but in such case shall purchase as much coverage as possible for such
amount.
 
REGULATORY MATTERS
 
     Transactions such as the merger are reviewed by the Antitrust Division of
the Department of Justice and by the Federal Trade Commission to ensure
compliance with antitrust laws. The Hart-Scott-Rodino Antitrust Improvements Act
of 1976, and its interpretive rules, govern this review. Under the Hart-Scott-
Rodino Act, Bayard and Nabors may not consummate the merger until they have
filed a notice with the Antitrust Division and the FTC and the applicable
waiting period expires or is terminated.
 
     On October 22, 1998, Bayard and Nabors filed their respective Premerger
Notification and Report Forms as required by the Hart-Scott-Rodino Act. On
November 20, 1998, the Antitrust Division requested that Bayard and Nabors
provide additional information and documents relevant to the proposed merger.
This request for additional information extends the applicable waiting period.
In particular, under the Hart-Scott-Rodino Act, Bayard and Nabors may not
consummate the merger for a period of 20 days from the date on which they
substantially comply with the information request. After the parties
substantially comply with the information request, the waiting period may be
extended only by court order or by consent of the parties.
 
     Bayard and Nabors are currently engaged in discussions with the Antitrust
Division regarding the competitive effects of the merger. At any time before or
after the merger, the Antitrust Division could take action to enjoin the merger
or to force divestiture of substantial assets of Bayard or Nabors or their
subsidiaries. Private parties and state attorneys general could also bring an
action under the antitrust laws in certain circumstances. Bayard and Nabors
cannot guarantee that the Antitrust Division, the FTC or others will not
challenge the merger and cannot predict the result should such a challenge
occur.
 
SOURCE AND AMOUNT OF FUNDS
 
     Nabors intends to finance its obligations to pay the cash portion of the
aggregate merger consideration with its working capital. The total cash cost to
Nabors of the merger consideration will be approximately $5.5 million.
 
MANAGEMENT OF NABORS FOLLOWING THE MERGER
 
     It is not anticipated that any of the members of the Bayard Board will
serve on the Board of Directors of Nabors and, accordingly, the composition of
the Board of Directors of Nabors will not change as the result of the merger.
Likewise, it is not anticipated that any officers of Bayard will become officers
of Nabors after the consummation of the merger. However, one executive officer
of Bayard is expected to enter into an employment agreement with Nabors Drilling
USA, Inc., a wholly owned subsidiary of Nabors. See "-- Interests of Certain
Persons in the Merger."

RIGHTS OF DISSENTING STOCKHOLDERS
 
     A holder of record of shares of Bayard common stock on the record date who
complies with the procedures set forth in Section 262 of the Delaware General
Corporation Law will be entitled to appraisal rights in connection with the
merger. Holders of warrants and options issued by Bayard are not entitled to
appraisal rights in connection with the merger. The following discussion is not
a complete statement of the law pertaining to appraisal rights under the
Delaware General Corporation Law and is qualified in its entirety by the full
text of Section 262, which is reprinted in its entirety as Annex C to this
document. Except as set forth in Section 262, Bayard's stockholders will not be
entitled to appraisal rights in connection with the merger.
 
     Under Section 262, record holders of Bayard common stock who comply with
the procedures set forth in Section 262 will be entitled to have their shares
appraised by the Delaware Court of Chancery and to receive payment of the "fair
value" of their shares, exclusive of any element of value arising from the
accomplishment or expectation of the merger, together with a fair rate of
interest, if any, as determined by the court.
 
     Under Section 262, where a merger agreement is to be submitted for adoption
at a meeting of stockholders, as in the case of the special meeting, not less
than 20 days before the meeting, a company must notify each of its stockholders
of record at the close of business on the record date for the meeting that
appraisal rights are available and include in each such notice a copy of Section
262. THIS DOCUMENT CONSTITUTES THE REQUIRED NOTICE TO HOLDERS OF BAYARD COMMON
STOCK. Any stockholder who wishes to exercise appraisal rights should review the
following discussion and Annex C carefully, because failure to timely and
properly comply with the procedures specified in Section 262 will result in the
loss of appraisal rights.
 
     A STOCKHOLDER WISHING TO EXERCISE APPRAISAL RIGHTS MUST DELIVER TO BAYARD,
BEFORE THE VOTE ON THE ADOPTION OF THE MERGER AGREEMENT AT THE SPECIAL MEETING,
A WRITTEN DEMAND FOR APPRAISAL OF THE HOLDER'S SHARES OF STOCK. The demand must
inform Bayard of the identity of the stockholder and must state that the
stockholder intends to demand an appraisal of his or her shares of Bayard common
stock. A vote against the adoption of merger agreement will not satisfy this
requirement. ALL WRITTEN DEMANDS FOR APPRAISAL OF SHARES SHOULD BE MAILED OR
DELIVERED TO BAYARD, 4005 NORTHWEST EXPRESSWAY, SUITE 550E, OKLAHOMA CITY,
OKLAHOMA 73116, ATTENTION: SECRETARY, SO AS TO BE RECEIVED BEFORE THE VOTE ON
THE ADOPTION OF THE MERGER AGREEMENT.
 
     A STOCKHOLDER WISHING TO EXERCISE APPRAISAL RIGHTS MUST HOLD OF RECORD THE
SHARES IN QUESTION ON THE RECORD DATE AND MUST CONTINUE TO HOLD SUCH SHARES
THROUGH THE TIME OF THE MERGER. Accordingly, a holder of shares of Bayard common
stock who is the record holder of shares of Bayard common stock on the record
date, but who transfers such shares of Bayard common stock before the
consummation of the merger, will lose any right to appraisal in respect of such
shares of Bayard common stock.
 
     A holder of record of shares of Bayard common stock is entitled to assert
appraisal rights only with respect to the shares registered in that holder's
name. A demand for appraisal should be executed by or on behalf of the holder of
record fully and correctly, as the holder's name appears on the stock
certificates. If the shares are owned of record in a fiduciary capacity, such as
by a trustee, guardian or custodian, execution of the demand should be made in
that capacity; if the shares are owned of record by more than one person, as in
a joint tenancy or tenancy in common, the demand should be executed by or on
behalf of all joint owners. An authorized agent, including one or more joint
owners, may execute a demand for appraisal on behalf of a holder of record;
however, the agent must identify the record owner or owners and expressly
disclose the fact that, in executing the demand, the agent is agent for the
record owner or owners. A record holder such as a broker, who holds shares as
nominee for several beneficial owners, may exercise appraisal rights with
respect to the shares held for one or more beneficial owners, while not
exercising appraisal rights with respect to the shares held for other beneficial
owners; in that event, the written demand should set forth the number of shares
as to which appraisal is sought. Where no number of shares is expressly
mentioned, the demand will be presumed to cover all shares held in the name of
the record owner. Stockholders who hold their shares in brokerage accounts or
other nominee forms and who
                                       35
<PAGE>   41
 
wish to exercise appraisal rights are urged to consult with their brokers to
determine the appropriate procedures for the making of a demand for appraisal by
the nominee.
 
     STOCKHOLDERS ELECTING TO EXERCISE THEIR APPRAISAL RIGHTS UNDER SECTION 262
MUST NOT VOTE FOR ADOPTION OF THE MERGER AGREEMENT. Accordingly, a vote against
adoption of the merger agreement, or an abstention with respect to the merger
agreement, will not prevent a holder of Bayard common stock from exercising
appraisal rights, but a vote in favor of adoption of the merger agreement will
prevent such holder from exercising appraisal rights. However, IF A HOLDER OF
BAYARD COMMON STOCK RETURNS A SIGNED PROXY CARD, BUT DOES NOT SPECIFY A VOTE
AGAINST ADOPTION OF THE MERGER AGREEMENT OR A DIRECTION TO ABSTAIN, THEN THE
PROXY CARD, IF NOT REVOKED, WILL BE VOTED FOR THE MERGER, WHICH WILL HAVE THE
EFFECT OF WAIVING THAT STOCKHOLDER'S APPRAISAL RIGHTS.
 
     Within ten days after the merger, Bayard, as the surviving corporation in
the merger, must send a notice as to the effectiveness of the merger to each
person who has satisfied the appropriate provisions of Section 262. Within, but
not more than, 120 days after the merger, Bayard, or any holder of shares
entitled to appraisal rights under Section 262 who has complied with the
statutory procedures summarized above, may file a petition in the Delaware Court
of Chancery demanding a determination of the fair value of such shares. Bayard
is not under any obligation, and has no present intention, to file a petition
with respect to the appraisal of the fair value of the shares. Accordingly, it
is the obligation of the stockholders to initiate all necessary action to
perfect their appraisal rights within the time prescribed in Section 262.
 
     Within 120 days after the merger, any record holder of shares who has
complied with the requirements for exercise of appraisal rights will be
entitled, upon written request, to receive from Bayard a statement setting forth
the aggregate number of shares of Bayard common stock with respect to which
demands for appraisal have been received and the aggregate number of holders of
such shares. The statements must be mailed within ten days after Bayard receives
a written request therefor.
 
     If a petition for an appraisal is timely filed, then, after a hearing on
the petition, the Delaware Court of Chancery will determine the holders of
shares entitled to appraisal rights. The Delaware Court of Chancery may require
the stockholders who have demanded an appraisal for their shares and who hold
stock represented by certificates to submit their certificates of stock to the
Register in Chancery for notation thereon of the pendency of the appraisal
proceedings. If any stockholder fails to comply with such direction, the
Delaware Court of Chancery may dismiss the proceedings as to such stockholder.
 
     The Delaware Court of Chancery will appraise the "fair value" of the shares
of stockholders entitled to appraisal rights, exclusive of any element of value
arising from the accomplishment or expectation of the merger, together with a
fair rate of interest, if any, to be paid upon the amount determined to be the
fair value. Holders considering seeking appraisal should be aware that the fair
value of their shares as determined under Section 262 could be more than, the
same as or less than the value of the merger consideration that they would
otherwise receive if they did not seek appraisal of their shares. The Delaware
Supreme Court has stated that "proof of value by any techniques or methods which
are generally considered acceptable in the financial community and otherwise
admissible in court" should be considered in the appraisal proceedings. More
specifically, the Delaware Supreme Court has stated that: "Fair value, in an
appraisal context, measures 'that which has been taken from the shareholder,
viz., his proportionate interest in a going concern.' In the appraisal process
the corporation is valued 'as an entity,' not merely as a collection of assets
or by the sum of the market price of each share of its stock. Moreover, the
corporation must be viewed as an on-going enterprise, occupying a particular
market position in the light of future prospects." In addition, Delaware courts
have decided that the statutory appraisal remedy, depending on factual
circumstances, may or may not be a stockholder's exclusive remedy. The Delaware
Court of Chancery will also determine the amount of interest, if any, to be paid
upon the amounts to be received by persons whose shares have been appraised. The
costs of the action may be determined by the court and taxed upon the parties as
the court deems equitable. The court may also order that all or a portion of the
expenses incurred by any stockholder in connection with an appraisal, including
reasonable attorneys fees and the fees and expenses of experts utilized in the
appraisal proceeding, be charged pro rata against the value of all of the shares
entitled to appraisal.
 
                                       36
<PAGE>   42
 
     Any holder of shares who has duly demanded an appraisal in compliance with
Section 262 will not, after the effective time, be entitled to vote the shares
subject to the demand for appraisal for any purpose, and will not be entitled to
the payment of dividends or other distributions on those shares, except
dividends or other distributions payable to holders of record of shares of the
same class or series of stock as of a date before the merger.
 
     If any stockholder who demands appraisal of shares under Section 262 fails
to perfect, or effectively withdraws or loses, the right to appraisal, then the
shares held by such holder will be converted into the merger consideration. A
holder of shares will fail to perfect, or will effectively lose, the right to
appraisal if no petition for appraisal is filed within 120 days after the
merger. A holder may withdraw a demand for appraisal by delivering to Bayard a
written withdrawal of the demand for appraisal and acceptance of the merger,
except that any such attempt to withdraw made more than 60 days after the merger
will require the written approval of Bayard and no appraisal proceeding may be
dismissed as to any stockholder without the approval of the court.
 
     Failure to follow the steps required by Section 262 for perfecting
appraisal rights may result in the loss of appraisal rights. If a stockholder
fails to perfect a right to appraisal, the stockholder will still receive
consideration with respect to such shares of Bayard common stock in accordance
with the merger agreement. In view of the complexities of the foregoing
provisions of the Delaware General Corporation Law, Bayard stockholders who are
considering dissenting from the merger may wish to consult legal counsel.
 
ACCOUNTING TREATMENT
 
     The merger will be treated by Nabors as a "purchase," as that term is used
under United States generally accepted accounting principles, for accounting and
financial reporting purposes. Under this method of accounting, the purchase
price of Bayard, including direct costs of the merger, will be allocated to
assets and liabilities of the acquired company based upon their estimated fair
values, with the excess purchase consideration allocated to goodwill. The
results of Nabors' operations will include the results of operations of Bayard
commencing at the time of the merger. The Unaudited Pro Forma Financial
Statements appearing elsewhere in this document are based upon certain
assumptions and allocate the purchase price to assets and liabilities based upon
a preliminary allocation of the purchase price. The unaudited pro forma
adjustments and consolidated amounts are included for information purposes only.
If the merger is consummated, Nabors' consolidated financial statements will
reflect the effects of acquisition adjustments only from the effective time.

                  THE MERGER AGREEMENT AND RELATED AGREEMENTS
 
     The following is a summary of the material provisions of the merger
agreement, a copy of which is attached as Annex A to this document. This summary
is qualified in its entirety by reference to the full text of the merger
agreement.
 
THE MERGER
 
     Upon the terms and conditions of the merger agreement, and in accordance
with the Delaware General Corporation Law, at the effective time, Nabors'
acquisition subsidiary will be merged with and into Bayard and Bayard will
continue as the surviving corporation in the merger. As a result of the merger,
Bayard will become a wholly owned subsidiary of Nabors.
 
CONVERSION OF SECURITIES
 
     The Merger Consideration. Upon the consummation of the merger, each issued
and outstanding share of Bayard common stock, other than treasury shares held by
Bayard or its subsidiaries, shares held by Nabors or its subsidiaries and shares
held by persons who perfect and exercise appraisal rights, will be converted
into the right to receive 0.3375 shares of Nabors common stock and $0.30 in
cash. The share exchange ratio will be adjusted to reflect any changes in Bayard
common stock or Nabors common stock from any stock dividend, subdivision,
reclassification, recapitalization, split, combination or exchange of shares, or
if certain events described in the Bayard rights agreement occur.
 
     Exchange of Certificates. Promptly after the merger, transmittal forms will
be mailed to each holder of record of shares of Bayard common stock to be used
in forwarding his or her certificates evidencing such shares for surrender and
exchange for the merger consideration. After receipt of such transmittal form,
each holder of Bayard certificates should surrender the holder's Bayard stock
certificates to the exchange agent, and each holder will receive in exchange
certificates representing the whole number of shares of Nabors common stock to
which such holder is entitled, together with the cash consideration of $0.30 per
share for such holder's Bayard shares and any cash which may be payable instead
of a fractional share of Nabors common stock. Such transmittal forms will be
accompanied by instructions specifying other details of the exchange.
 
     STOCKHOLDERS SHOULD NOT SEND IN THEIR STOCK CERTIFICATES UNTIL THEY RECEIVE
A TRANSMITTAL FORM.
 
     Fractional Shares. No shares of Bayard common stock will be converted into
fractional shares of Nabors common stock. Each holder of Bayard certificates
which would otherwise represent the right to receive a fractional share of
Nabors common stock shall, at the time of surrender, be paid by the exchange
agent an amount in cash equal to the value of such fractional share based on the
average closing price per share of Nabors common stock as reported by the
Northeast edition of The Wall Street Journal for the ten consecutive trading
days ending on and including the fifth trading day before the closing of the
merger. All the fractional shares to which a single holder of Bayard common
stock would be entitled will be aggregated.
 
     Rights with Respect to Unexchanged Shares. After the merger, each Bayard
certificate, until properly surrendered and exchanged, will, for all purposes,
represent only the right to receive the number of shares of Nabors common stock
which the holder of the Bayard certificate is entitled to receive, together with
the cash consideration of $0.30 per share and any cash payment instead of a
fractional share of Nabors common stock. The holder of an unexchanged Bayard
certificate will not be entitled to receive dividends or other distributions, if
any, by Nabors with a record date after the effective time until the certificate
is surrendered, at which time such dividends and distributions, together with
the cash consideration and any cash payment instead of a fractional share of
Nabors common stock, will be paid to the holder without interest.
 
     Dissenting Shares. Any holders of Bayard common stock who have properly
perfected appraisal rights will not receive the merger consideration, but will
instead be entitled to receive a payment determined as provided by Section 262
of the Delaware General Corporation Law. However, if a holder of Bayard
                                       38
<PAGE>   44
 
common stock fails to perfect, withdraws or loses the right to appraisal, then
those holder's shares will be deemed to have been converted into the right to
receive the merger consideration as of the effective time. See "The
Merger -- Rights of Dissenting Stockholders."
 
     Stock Options. At the effective time, each of the outstanding Bayard stock
options will be converted into a Nabors stock option as follows:
 
     - each converted stock option will be exercisable for that number of whole
       shares of Nabors common stock equal to (1) the number of shares of Bayard
       common stock covered by the Bayard stock option, multiplied by (2) the
       share exchange ratio, rounded up to the nearest whole number of shares;
       and
 
     - the per share exercise price for the shares of Nabors common stock
       issuable upon the exercise of each converted stock option will be the
       quotient determined by (1) subtracting the cash consideration of $0.30
       per share from the exercise price per share of Bayard common stock for
       the Bayard stock option and dividing by (2) the share exchange ratio,
       rounding the resulting exercise price up to the nearest whole cent.
 
     Nabors has agreed to reserve for issuance the number of shares of Nabors
common stock that will become issuable upon the exercise of the converted Bayard
stock options. The new options will have the same vesting schedule and period of
exercise as applied to the Bayard stock options before the date of the merger
agreement, except that any converted option held by an employee of Bayard will
be fully vested if the employee is terminated without cause by Bayard within one
year after the merger. Nabors has agreed to file a registration statement with
the Securities and Exchange Commission with respect to the shares of Nabors
common stock subject to the converted options, and to use its best efforts to
keep the registration statement effective for so long as the converted options
remain outstanding.
 
     Where the merger agreement does not state otherwise, the converted Bayard
stock options will be subject to the terms and conditions of Nabors' 1998
Employee Stock Option Plan or a similar plan, and the form of stock option
agreement will be Nabors' standard form as is in effect on the date of the
merger agreement. At Nabors' request, Nabors and Bayard will negotiate in good
faith to allow Nabors to adopt Bayard's stock option plans, instead of
converting Bayard stock options into Nabors stock options.
 
     Warrants. Immediately following the merger, each of the outstanding
warrants to purchase shares of Bayard common stock will remain outstanding on
the same terms as in effect immediately before the merger, except that each
warrant will be exercisable for:
 
     - that number of whole shares of Nabors common stock equal to (1) the
       number of shares of Bayard common stock covered by the Bayard warrant,
       multiplied by (2) the share exchange ratio, rounded up to the nearest
       whole number of shares; and
 
     - the amount of cash equal to (1) the number of shares of Bayard common
       stock covered by the Bayard warrant, multiplied by (2) the cash
       consideration of $0.30 per share.
 
     Nabors has agreed to reserve for issuance the number of shares of Nabors
common stock that will become issuable upon the exercise of Bayard warrants.
 
REPRESENTATIONS AND WARRANTIES
 
     The merger agreement contains various representations and warranties by
Nabors, Nabors' acquisition subsidiary and Bayard with respect to, among other
things:
 
     - organization, good standing and corporate power;
 
     - capitalization;
 
     - corporate authority relative to the merger agreement;
 
     - Securities and Exchange Commission reports and financial statements;
                                       39
<PAGE>   45
 
     - absence of undisclosed liabilities;
 
     - absence of violations of law;
 
     - environmental laws and regulations;
 
     - benefit plans;
 
     - absence of certain changes or events;
 
     - litigation;
 
     - lack of ownership of the other party's stock;
 
     - tax matters;
 
     - insurance;
 
     - intellectual property;
 
     - material contracts;
 
     - required vote of stockholders to approve the merger; and
 
     - brokers' fees.
 
     In addition, Bayard has also made certain representations and warranties
with respect to the Bayard rights agreement and the opinion of its financial
advisor. Nabors and Nabors' acquisition subsidiary have also made certain
representations and warranties with respect to the ownership of Nabors'
acquisition subsidiary and its activities.
 
     A number of the representations and warranties made by Bayard and Nabors in
the merger agreement contain qualifications which limit the scope of the
representations and warranties to matters which would have a material adverse
effect on the applicable company and its subsidiaries, taken as a whole. In
general, the merger agreement provides that a material adverse effect will be
deemed to have occurred if there is a change or effect which has caused, or may
be reasonably likely to cause, actual monetary loss which exceeds $75.0 million,
in the case of Nabors, or $7.5 million, in the case of Bayard. Actual or
anticipated events or effects which were disclosed to or known by the parties
prior to or on February 12, 1999 are not considered material adverse effects for
purposes of the merger agreement. Similarly, effects attributable to general
economic conditions or the oil and gas or contract drilling industries in
general are not considered material adverse effects.
 
COVENANTS
 
     Covenants of Bayard. Bayard has agreed that until the merger, except as
contemplated in the merger agreement or with the consent of Nabors, it will,
among other things:
 
     - conduct its business in the usual and ordinary course consistent with
       past practice;
 
     - use its commercially reasonable efforts to preserve substantially intact
       its business organizations, maintain its rights and franchises, retain
       the services of its officers and key employees and maintain its material
       relationships with its customers and suppliers;
 
     - use its commercially reasonable efforts to maintain and keep its
       properties and assets in their current condition in all material
       respects, allowing for ordinary wear and tear; and
 
     - use its commercially reasonable efforts to keep in full force and effect
       insurance and bonds comparable in amount and scope of coverage to that
       currently maintained.
 
                                       40
<PAGE>   46
 
     In addition, Bayard has agreed that, except as contemplated by the merger
agreement, as set forth in the disclosure schedules delivered by Bayard to
Nabors or with the consent of Nabors, it will not take any of the following
actions:
 
     - increase the compensation payable to any director or officer, grant or
       agree to grant any severance or termination pay, other than as provided
       by any normal severance policy in effect on the date of the merger
       agreement, or adopt or amend any employee benefit plan;
 
     - declare or pay any dividend or other distribution in respect of
       outstanding shares of capital stock, subject to certain exceptions;
 
     - redeem, purchase or otherwise acquire its shares or options, warrants or
       other rights to acquire securities of Bayard or any of its subsidiaries,
       subject to certain exceptions, or effect any recapitalization, or split,
       combination or reclassification of any of the stock of Bayard or any of
       its subsidiaries;
 
     - issue any shares or any security that is convertible into or exercisable
       for Bayard's stock or that of any of its subsidiaries, subject to certain
       exceptions, or amend or otherwise modify the terms of any option, warrant
       or other security so as to create terms more favorable for the holder, or
       accelerate the vesting of any Bayard stock options;
 
     - acquire any equity interest in excess of $1.0 million or acquire any
       assets which are material, except in accordance with ordinary business
       operations;
 
     - dispose of any material assets, subject to certain exceptions;
 
     - amend its Restated Certificate of Incorporation or amend its Amended and
       Restated Bylaws in a manner that might have an adverse impact on the
       transactions contemplated by the merger agreement;
 
     - change any of its methods of accounting or tax reporting, subject to
       certain exceptions;
 
     - change any election relating to taxes, or settle or compromise any matter
       relating to taxes over $250,000;
 
     - spend more than $1.0 million in the aggregate on the purchase of
       equipment or supplies, subject to certain exceptions;
 
     - incur any debt, with certain exceptions; and
 
     - take any action that would, or is reasonably likely to, result in any of
       its representations or warranties being untrue or in any of the
       conditions to the merger not being satisfied.
 
     Covenants of Nabors. Nabors has agreed that, until the merger, except as
contemplated in the merger agreement or with the consent of Bayard, it will not,
and will cause Nabors' acquisition subsidiary not to, among other things:
 
     - amend any of the material terms or provisions of Nabors common stock;
 
     - knowingly take any action which would result in Nabors common stock not
       being traded on AMEX;
 
     - declare or pay any dividends or distributions on outstanding shares of
       stock; or
 
     - take any action that would, or is reasonably likely to, result in any of
       Nabors' or Nabors' acquisition subsidiary's representations or warranties
       being untrue or in any of the conditions to the merger not being
       satisfied.
 
     Registration Rights. Nabors has agreed to grant certain registration rights
to holders of Bayard common stock who would be subject to Rule 145 and Rule 144
of the Securities Act of 1933. The grant of registration rights will be
evidenced by an agreement to be entered into before the effective time. This
                                       41
<PAGE>   47
 
agreement will, among other things, allow the holders subject to Rule 144 or
Rule 145 to collectively demand registration of not less than 1,000,000 shares
of Nabors common stock. See "The Merger -- Federal Securities Law Consequences."
 
     No Solicitation. The merger agreement prohibits Bayard and its subsidiaries
from, directly or indirectly:
 
     - initiating, soliciting or encouraging, including by way of furnishing
       information or assistance, or taking any other action to facilitate, the
       types of acquisition proposals described below and referred to in this
       document as "company acquisition proposals;"
 
     - entering into discussions or negotiating with any person or entity in
       furtherance of a company acquisition proposal;
 
     - entering into an agreement with respect to the types of acquisition
       transactions described below and referred to in this document as "company
       acquisition transactions" or agreeing to or endorsing any company
       acquisition proposal; or
 
     - authorizing or permitting any of the officers, directors or employees of
       Bayard or any of its subsidiaries or any investment banker, financial
       advisor, attorney, accountant or other representative retained by Bayard
       or any of its subsidiaries to take any such action.
 
     The merger agreement requires Bayard to advise Nabors of any company
acquisition proposal within two days of receiving such proposal, and to deliver
a copy of any written proposal to Nabors.
 
     However, the merger agreement does not prohibit the Bayard Board from:
 
     - complying with Rule 14e-2 promulgated under the Securities Exchange Act
       of 1934 with regard to a company acquisition proposal; or
 
     - furnishing information to, or entering into discussions or negotiations
       with, any person or entity in connection with an unsolicited, bona fide,
       written company acquisition proposal obtained before stockholder approval
       of the merger and recommending the same to Bayard's stockholders or
       otherwise communicating with Bayard's stockholders regarding such
       proposal in a manner permitted by law, if, and only to the extent that:
 
          (1) the Bayard Board, after consultation with legal counsel,
              determines in good faith that such action is required for the
              Bayard Board to comply with its fiduciary duties to stockholders
              imposed by the Delaware General Corporation Law;
 
          (2) before furnishing such information to, or entering into
              discussions or negotiations with, such person or entity, Bayard:
 
             (a) provides two business days' written notice to Nabors of such
        action; and
 
             (b) obtains from such person or entity a customary confidentiality
        agreement; and
 
          (3) Bayard determines in good faith and after consultation with its
              financial advisor that, in light of the information furnished to
              it relating to such company acquisition proposal, the company
              acquisition transaction contemplated would, if consummated, result
              in a more favorable transaction than the transaction contemplated
              by the merger agreement, taking into account the long-term
              prospects and interests of Bayard and its stockholders.
 
     A "company acquisition proposal" is any inquiry or proposal which relates
to or contemplates a company acquisition transaction.
 
     A "company acquisition transaction" means any of the following
transactions:
 
     - any merger, consolidation, share exchange or other business combination
       involving Bayard or any of its subsidiaries, subject to certain
       exceptions;
 
                                       42
<PAGE>   48
 
     - any sale, exchange, transfer or other disposition to any person other
       than Nabors or any of its subsidiaries of properties or assets of Bayard
       or any of its subsidiaries which constitute:
 
          (1) all or substantially all of the properties and assets of Bayard;
 
          (2) all or substantially all of the properties and assets of any
              significant subsidiary, or a material division or other business
              unit of Bayard or any significant subsidiary; or
 
          (3) properties and assets which are material to the business or
              operations of Bayard and its subsidiaries, taken as a whole;
 
     - any tender offer or exchange offer by any person other than Nabors or any
       of its subsidiaries for 15% or more of the outstanding shares of Bayard
       common stock; or
 
     - any acquisition of shares of Bayard common stock by any person or group
       other than Nabors or any of its subsidiaries which would require an
       amendment, waiver, termination or alteration of the Bayard rights
       agreement so that such acquisition would not result in such person
       becoming an "acquiring person" under the terms of the Bayard rights
       agreement.
 
     Access and Information. Both Nabors and Bayard have agreed, subject to
certain limitations, to allow one another reasonable access to information
concerning its business, properties, contracts, records and personnel.
 
     Confidentiality. Between the date of the merger agreement and the effective
time, Bayard and Nabors have agreed to maintain in confidence, and to cause
their representatives to maintain in confidence, and not to use to the detriment
of a party to the merger agreement, any information obtained from a party to the
merger agreement or its subsidiaries in connection with the merger agreement or
any related transactions, with certain exceptions. Upon any termination of the
merger agreement, Bayard and Nabors will return or destroy all confidential
information provided by the other.
 
CLOSING CONDITIONS
 
     Conditions Applicable to All Parties. The following conditions, among
others, must be satisfied before the merger, unless waived by the parties to the
merger agreement:

       this document is a part;
 
     - the merger agreement and the merger shall have been approved and adopted
       by the holders of a majority of the outstanding shares of Bayard common
       stock;

     - Bayard and Nabors shall have received certain opinions as to tax matters
       from their counsel;

     Conditions Applicable to Nabors. Nabors' obligations to effect the merger
and the other transactions contemplated by the merger agreement are subject to
the satisfaction or waiver of certain additional conditions, including:
 
     - the accuracy of Bayard's representations and warranties, with such

     - Bayard's performance in all material respects of its obligations under

     Conditions Applicable to Bayard. Bayard's obligations to effect the merger
and the other transactions contemplated by the merger agreement are subject to
the satisfaction or waiver of certain additional conditions, including:
 
     - the accuracy of Nabors' and Nabors' acquisition subsidiary's
       representations and warranties, with such exceptions as would not have a
       material adverse effect on Nabors;
 
     - Nabors' performance in all material respects of its obligations under the
       merger agreement; and
 
     - the lack of, since the date of the merger agreement, an event having a
       material adverse effect on Nabors.
 
TERMINATION
 
     The merger agreement may be terminated at any time before the merger, only
in the following ways:
 
     (1) by mutual written consent of Nabors and Bayard;
 
     (2) by Nabors, upon an intentional breach by Bayard of any of its covenants
         or agreements, or if a material representation or warranty of Bayard is
         untrue, in either case causing certain conditions not to be satisfied;
         except that Bayard shall have an opportunity to cure the breach by
         exercising its reasonable best efforts;
 
     (3) by Bayard, upon an intentional breach by Nabors of any of its covenants
         or agreements, or if a material representation or warranty of Nabors is
         untrue, in either case causing certain conditions not to be satisfied;
         except that Nabors shall have an opportunity to cure the breach by
         exercising its reasonable best efforts;
 
     (4) by either Nabors or Bayard, if certain final, nonappealable orders,
         decrees or rulings prevent the consummation of the merger;
 
     (5) by either Nabors or Bayard, if the merger does not occur before
         September 30, 1999, unless the failure to consummate the merger by such
         date results from the action or failure to act of the party seeking to
         terminate the merger agreement;
 
     (6) by either Nabors or Bayard, if Bayard holds the special meeting but the
         merger agreement does not receive the required stockholder approval;
 
     (7) by Nabors, if:
 
        (a) the Bayard Board withdraws, or materially modifies or materially
            changes, its recommendation of the merger agreement or the merger in
            a manner adverse to Nabors or Nabors' acquisition subsidiary, or
            resolves to do so;
 
        (b) the Bayard Board recommends a company acquisition proposal or, after
            ten business days following the public announcement, or, in the case
            of a tender offer, following the commencement of such tender offer,
            of any company acquisition proposal, has not recommended against
            accepting such company acquisition proposal or has taken no position
            with respect to such company acquisition proposal; or
 
        (c) Bayard changes the provisions of the Bayard rights agreement in such
            a manner that any person other than Nabors or Nabors' acquisition
            subsidiary has been permitted to acquire beneficial ownership of, or
            the right to acquire beneficial ownership of, or any group has been
            formed that beneficially owns, or has the right to acquire
            beneficial ownership of, more
 
                                       44
<PAGE>   50
 
            than 15% of the then outstanding shares of capital stock of Bayard,
            in each case without triggering the Bayard rights agreement; or
 
     (8) by Bayard, if the Bayard Board determines that proceeding with the
         merger would be inconsistent with its fiduciary obligations under
         certain circumstances; however, Bayard must give Nabors five days'
         advance notice of its intention to terminate, must consider any new
         proposals made by Nabors and must pay to Nabors the sum of $5.0
         million, plus up to $500,000 in reasonable third party costs referred
         to below under "-- Fees, Expense and Other Payments."
 
FEES, EXPENSES AND OTHER PAYMENTS
 
     Nabors and Bayard will bear their own costs and expenses in connection with
the merger agreement and the related transactions, except as follows:
 
     - Nabors and Bayard will share equally the costs and expenses related to
       printing, filing and mailing all Securities and Exchange Commission and
       other regulatory filings related to these transactions;
 
     - upon completion of the merger, all costs borne by Nabors and Bayard will
       be borne by the surviving corporation;
 
     - Bayard must pay Nabors a fee of $5.0 million, plus up to $500,000 in
       reasonable third party costs incurred by Nabors, if the merger agreement
       is terminated as described in item (6), (7) or (8) under
       "-- Termination"; and
 
     - if the merger agreement is terminated by either party as described in
       item (2) or (3) under "-- Termination," then the breaching party must pay
       the terminating party a fee of $7.5 million (if Bayard is the breaching
       party) or $15.0 million (if Nabors is the breaching party).
 
AMENDMENT; WAIVER
 
     The merger agreement may be amended by Nabors or Bayard by action of their
respective Boards of Directors at any time before the merger. However, after the
adoption of the merger agreement by the stockholders of Bayard, no amendment may
be made which by the Delaware General Corporation Law requires the further
approval of stockholders.
 
     At any time before the merger, Nabors and Bayard may extend the time for
the performance of any of the obligations or other acts of the other, waive any
inaccuracies in the representations and warranties of the other party, or waive
compliance by the other parties with any of the agreements or conditions.
 
STOCK OPTION AGREEMENT
 
     In the stock option agreement, Bayard granted Nabors an option to purchase
up to 3,620,595 shares, but no more than 19.9% of the outstanding shares, of
Bayard's common stock at a price of $5.50 per share. If Bayard issues any
additional shares after the date of the stock option agreement, then the number
of shares issuable upon exercise of the option will be adjusted to reflect 19.9%
of the outstanding shares of Bayard.
 
     Subject to certain exceptions, Nabors is entitled to exercise all or any
part of the option, at any one time, if the following occurs:
 
     - the merger agreement is terminated as described in item (6) under
       "-- Termination" and, within 180 days of the date of such termination,
       Bayard authorizes, recommends, publicly proposes, or enters into an
       agreement to effect a company acquisition transaction, or publicly
       announces an intention to do so; or
 
     - the merger agreement is terminated as described in item (2), (7) or (8)
       under "-- Termination."
 
     Upon the exercise of the option, Nabors will pay to Bayard an amount in
cash equal to the product of $5.50 and the number of shares of Bayard common
stock to be purchased by Nabors. The stock option
                                       45
<PAGE>   51
 
agreement does not contain a "put" or "cashless exercise" feature that would
permit Nabors to realize the economic benefit of the option without payment of
the exercise price to Bayard.
 
     The option will expire, subject to certain exceptions, on the earliest of:
 
     - the time of the merger;
 
     - one year after termination of the merger agreement as described in item
       (2), (7) or (8) under "-- Termination";
 
     - 180 days after termination of the merger agreement as described in item
       (6) under "-- Termination"; and
 
     - the date of termination of the merger agreement as described in item (1),
       (3), (4) or (5) under "-- Termination."
 
     The stock option agreement also grants certain registration rights to
Nabors with respect to any shares of Bayard common stock acquired upon exercise
of the option. In addition, the stock option agreement imposes certain
restrictions on the transfer of those shares. These restrictions prohibit any
transfer of the shares by Nabors, except in an underwritten public offering or
to any person who would not, to the knowledge of Nabors after reasonable
inquiry, hold more than 4.9% of the total voting power of Bayard stock after
giving effect to such transfer.
 
STOCKHOLDER AGREEMENTS
 
     Carl B. Anderson, AnSon Partners, L.L.C., as successor in interest to AnSon
Partners Limited Partnership, James E. Brown, Energy Spectrum Partners LP and
Wil-Cas Investments, L.P. have each entered into a stockholder agreement with
Nabors. These stockholders hold as of the record date 2,645,725 shares of Bayard
common stock, which represent approximately 14.5% of the outstanding shares of
such class. See "Principal Stockholders of Bayard."
 
     The stockholder agreements require these stockholders to vote all of their
shares in favor of the merger, the merger agreement and the transactions
contemplated by the merger agreement. In addition, these stockholders are
required to vote against any action or agreement that would result in a breach
in any material respect of any covenant, representation or warranty or any other
material obligation or agreement of Bayard under the merger agreement. These
stockholders are further required to vote against any company acquisition
transaction and against any proposal regarding any change in a majority of the
Bayard Board, the present capitalization of Bayard, any amendment of Bayard's
Certificate of Incorporation or Bylaws, or any other material change in Bayard's
corporate structure or business, to the extent that any such proposal is
intended to, or could reasonably be expected to, impede, interfere with, delay,
postpone or materially adversely affect the merger or the transactions
contemplated by the merger agreement or the stockholder agreements or could
implement or lead to any company acquisition transaction.
 
     The consenting stockholders have also irrevocably appointed Nabors as their
proxy to demand a special meeting of the stockholders of Bayard to consider any
action related to the merger agreement or the merger, and to vote their shares
with respect to any matters described in the above paragraph.
 
     The stockholder agreements will terminate at the time of the merger or if
the merger agreement is terminated in accordance with its terms. They will also
terminate if there is an amendment to the merger agreement which is materially
adverse to the consenting stockholders.
 
AMENDMENT OF BAYARD RIGHTS AGREEMENT
 
     Under the terms of the Bayard rights agreement, upon the occurrence of
certain events, including transactions of the type contemplated by the merger
agreement and the stock option agreement, the holder of a Right issued under the
Bayard rights agreement, other than an "acquiring person," as defined in the
Bayard rights agreement, is entitled to receive, upon exercise of such Right, a
number of shares of Bayard
                                       46
<PAGE>   52
 
common stock having a current market price equal to two times the exercise price
of the Right. For additional information regarding the Bayard rights agreement,
see "Comparison of Stockholder Rights -- Bayard Rights Agreement."
 
     Immediately before the execution of the merger agreement, the Bayard rights
agreement was amended so that the distribution and exercise of the Rights would
not be triggered by Nabors solely as a result of entering into and consummating
the transactions contemplated by the merger agreement, the stock option
agreement and the stockholder agreements. Specifically, the amendment to the
Bayard rights agreement provides, among other things, that:
 
     - the Expiration Date, as defined in the Bayard rights agreement, shall
       occur immediately before the time of the merger;
 
     - neither Nabors nor any of its affiliates or associates will be considered
       to be an Acquiring Person, as defined in the Bayard rights agreement,
       unless Nabors or any of its affiliates or associates acquires beneficial
       ownership of 20% or more of the outstanding shares of Bayard common
       stock, subject to certain exceptions; and
 
     - the consummation of the merger, any transaction contemplated by the
       merger agreement, the stock option agreement or the stockholder
       agreements will not:
 
          (1) constitute a Flip-In Event, Flip-Over Event, Stock Acquisition
              Date, Flip-In Trigger Date or Distribution Date, as such terms are
              defined in the Bayard rights agreement;
 
          (2) cause Nabors or any of its subsidiaries to be deemed an Acquiring
              Person, as defined in the Bayard rights agreement; or
 
          (3) cause the Rights provided for in the Bayard rights agreement to be
     exercisable.

                        FEDERAL INCOME TAX CONSEQUENCES
 
     The following discussion is a summary of the material United States federal
income tax consequences of the merger. Such discussion deals only with persons
that are citizens or residents of the United States or are entities formed under
the laws of the United States or any state or locality within the United States.
This summary assumes that the holders of Bayard common stock have held such
stock as a capital asset. The discussion does not address all aspects of federal
income taxation that may be important to particular stockholders and may not be
applicable to certain special classes of stockholders, including without
limitation, stockholders who are not citizens or residents of the United States,
stockholders who acquired their stock through the exercise of employee stock
options or otherwise as compensation, stockholders that are corporations subject
to the alternative minimum tax, insurance companies, tax-exempt organizations,
financial institutions, securities dealers, broker-dealers, or foreign
partnerships or foreign corporations. The following discussion also does not
discuss tax consequences to holders of outstanding Bayard warrants or stock
options. No information is provided in this document with respect to the tax
consequences, if any, of the merger under applicable foreign, state and local
laws.
 
     This summary is based on statutes, regulations, rulings, and judicial
decisions in effect at the date of this document. Future legislative, judicial
or administrative changes or interpretations could alter or modify these
statements and conclusions. Any such changes or interpretations could be
retroactive and could affect the tax consequences to stockholders as described
in this document. Neither Nabors nor Bayard has requested a ruling from the
Internal Revenue Service with regard to any of the federal income tax
consequences of the merger, and the discussion as to the federal income tax
consequences of the merger set forth below will not be binding on the IRS. EACH
STOCKHOLDER IS URGED TO CONSULT WITH HIS OR HER OWN TAX ADVISOR AS TO THE
PARTICULAR TAX CONSEQUENCES TO SUCH HOLDER OF THE MERGER DESCRIBED IN THIS
DOCUMENT, INCLUDING THE APPLICABILITY AND EFFECT OF ANY STATE, LOCAL OR FOREIGN
TAX LAWS, AND OF CHANGES TO APPLICABLE TAX LAWS.
 
QUALIFICATION OF MERGER AS A REORGANIZATION
 
     Based upon certain representations of Bayard and Nabors, and the
assumptions identified below:
 
     - the merger will be treated for federal income tax purposes as a
       reorganization within the meaning of Section 368(a) of the Internal
       Revenue Code of 1986;
 
     - each of Nabors, Nabors' acquisition subsidiary and Bayard will be a party
       to a reorganization within the meaning of Section 368(b) of the tax code;
 
     - no gain or loss will be recognized by Nabors, Nabors' acquisition
       subsidiary or Bayard as a result of the merger; and
 
     - except as described below with respect to fractional shares, Bayard
       stockholders will not recognize any loss as a result of the merger and
       will recognize gain as a result of the merger only to the extent of the
       lesser of the amount of cash received in the merger, other than cash
       received instead of fractional shares, or the amount, if any, by which
       the value of the merger consideration, other than cash received instead
       of fractional shares, exceeds the stockholder's tax basis in the Bayard
       shares surrendered in the merger.
 
     These conclusions are based on the following assumptions:
 
     - the representations of Bayard and Nabors remain true as of the date of
       the closing;
 
     - as of the date of the closing, Nabors common stock continues to represent
       at least 80% of the value of the total consideration furnished by Nabors
       and Nabors' acquisition subsidiary in the merger; and
 
     - the merger and related transactions take place as described in the merger
       agreement.
 
                                       48
<PAGE>   54
 
     It is a condition to the merger that Bayard shall have received a tax
opinion of Baker & Botts, L.L.P., counsel to Bayard, and that Nabors shall have
received a tax opinion of Baker & McKenzie, counsel to Nabors, each to the
effect of the foregoing. Such tax opinions, as well as the description of tax
consequences set forth in this document, will be based on assumptions relating
to certain facts and circumstances of, and the intentions of the parties to, the
merger. These assumptions either will have been made with the consent of Bayard
or Nabors or will be based upon certain representations of fact made by Bayard
or Nabors, or certain members of management of Bayard or Nabors. These
assumptions and representations of fact will primarily relate to the type and
value of the consideration to be received by Bayard stockholders in the merger,
the continued operation and level of retention of Bayard's historic business and
assets by Bayard or Nabors after the merger, the continued ownership and control
of Bayard by Nabors after the merger, and continuity of Bayard stock ownership
before the merger, and Nabors' stock ownership after the merger, by Bayard
stockholders. An opinion is not binding on the IRS or the courts and, therefore,
the delivery of such tax opinions cannot assure that the IRS or the courts will
treat the merger as a reorganization within the meaning of Section 368(a) of the
tax code.
 
     If it were determined that the merger did not qualify for federal income
tax purposes as a reorganization within the meaning of Section 368(a) of the tax
code, a stockholder of Bayard generally would recognize capital gain or loss for
tax purposes.
 
     The following discussion assumes that the merger will be treated as a
reorganization within the meaning of Section 368(a) of the tax code.
 
CONSEQUENCES OF MERGER TO NABORS, NABORS' ACQUISITION SUBSIDIARY AND BAYARD
 
     No gain or loss will be recognized by Nabors, Nabors' acquisition
subsidiary or Bayard or by any of their respective subsidiaries as a result of
the consummation of the merger.
 
CONSEQUENCES OF MERGER TO BAYARD STOCKHOLDERS
 
     Except as described in the following paragraph with respect to fractional
shares, Bayard stockholders will not recognize any loss as a result of the
merger. A Bayard stockholder will recognize gain as a result of the merger only
to the extent of the lesser of:
 
     - the amount of cash received by such Bayard stockholder in the merger,
       other than cash received instead of fractional shares; or
 
     - the amount, if any, by which the value of the merger consideration
       received by the Bayard stockholder exceeds the stockholder's tax basis in
       the Bayard shares surrendered in the merger.
 
Any such gain will generally be capital gain, provided that the Bayard
stockholder owns less than 1% of the outstanding shares of Nabors common stock
before the merger. The tax basis of Nabors common stock received in the merger
will equal the tax basis of Bayard common stock surrendered in the merger, plus
the amount of gain recognized by the stockholder under the rules described above
in this paragraph, less the amount of cash received by the stockholder, other
than cash received instead of a fractional share.
 
     The holding period of Nabors common stock received will include the holding
period of Bayard common stock surrendered in exchange for the Nabors common
stock.
 
     A holder of Bayard common stock who receives cash in the merger instead of
a fractional share of Nabors common stock will be treated as having received
that fractional share of stock through the merger and then as having received
the cash in a redemption of the fractional share of stock. Such a holder will
generally recognize capital gain or loss on the deemed redemption equal to the
difference between the amount of cash received and the holder's adjusted tax
basis in the fractional share of Nabors common stock deemed surrendered in
exchange for such cash.
 
                                       49
<PAGE>   55
 
CONSEQUENCES OF PRE-MERGER SALE OF BAYARD STOCK
 
     Bayard stockholders who sell shares of Bayard common stock in the market
before the merger would generally recognize capital gain or loss in an amount
equal to the difference between the amount received in the sale and the
stockholder's tax basis in the shares that are sold. Any such capital gain or
loss would be long-term capital gain or loss if the shares have been held for
more than 12-months at the time of the sale.
 
BACKUP WITHHOLDING
 
     A Bayard stockholder may be subject to backup withholding at the rate of
31% with respect to cash payments received in the merger unless either:
 
     - the stockholder is an entity that is exempt from withholding, including
       corporations, tax-exempt organizations and certain qualified nominees,
       and demonstrates this fact when required; or
 
     - the stockholder provides its taxpayer identification number, which for an
       individual would be the stockholder's social security number, certifies
       that the identification number provided is correct and that the
       stockholder has not been notified by the IRS that it is subject to backup
       withholding because it has under reported interest or dividends, and
       otherwise complies with applicable requirements of the backup withholding
       rules.
 
A Bayard stockholder who does not provide its correct taxpayer identification
number may be subject to penalties imposed by the IRS. Backup withholding is not
an additional tax but, rather, is a method of tax collection. Bayard
stockholders will be entitled to credit any amounts withheld under the backup
withholding rules against their actual tax liabilities.

          UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL STATEMENTS
 
     The following unaudited pro forma combined condensed financial statements
give effect to the acquisition of all of the outstanding capital stock of Bayard
by Nabors. The pro forma combination of Nabors and Bayard has been accounted for
under the purchase method of accounting.
 
     The Unaudited Pro Forma Combined Condensed Balance Sheet is derived from
the unaudited condensed consolidated balance sheets of Nabors and Bayard and is
presented as if the merger was consummated on the balance sheet date. The
Unaudited Pro Forma Combined Condensed Statements of Operations for the nine
months ended September 30, 1998 and the twelve months ended December 31, 1997
are presented as if the merger was consummated as of January 1, 1997. Nabors
results have been recast to conform to the presentation of the twelve months
ended December 31, 1997 by adjusting Nabors audited results for the year ended
September 31, 1997 to exclude the unaudited results for the quarter ended
December 31, 1996 and to include the unaudited results for the quarter ended
December 31, 1997. The Pro Forma Statement of Operations for the twelve months
ended December 31, 1997 also gives effect to the results of operations for Trend
Drilling Co., Ward Drilling Company, Inc., and Bonray Drilling Corporation
before their acquisition by Bayard, all of which occurred at various dates in
1997, as if such acquisitions occurred on January 1, 1997.
 
     The unaudited pro forma financial statements do not purport to indicate
what the combined results of operations of Nabors and Bayard would have been had
the merger occurred as of the dates indicated or the results of operations that
may be obtained in the future. The Unaudited Pro Forma Combined Condensed
Statements of Operations do not reflect the anticipated cost savings resulting
from integration of the operations of Nabors and Bayard. The pro forma
adjustments described in the accompanying notes are based on estimates derived
from information currently available.
 
     The unaudited pro forma financial information should be read in conjunction
with the consolidated financial statements and related notes of Nabors and
Bayard contained in the Annual Report on Form 10-K of Nabors for the year ended
September 30, 1997 and the Annual Report on Form 10-K of Bayard for the year
ended December 31, 1997 and each company's Quarterly Report on Form 10-Q for the
period ended September 30, 1998. The Form 10-K and Form 10-Q of Nabors are
incorporated by reference into this document. The consolidated financial
statements of Bayard and related notes are included in this document.
Additionally, reference should be made to Nabors' Transition Period Report on
Form 10-Q for the three month period ended December 31, 1997, which is
incorporated into this document by reference.

                         CONDENSED FINANCIAL STATEMENTS
 
     The following is a summary of the significant assumptions and adjustments
used in preparing the Unaudited Pro Forma Combined Condensed Balance Sheet as of
September 30, 1998 and the Unaudited Pro Forma Combined Condensed Statements of
Operations for the nine months ended September 30, 1998 and for the twelve
months ended December 31, 1997.
 
     (a) To reflect the purchase of Bayard for $5.46 million in cash and the
         issuance of 6,140,456 shares of Nabors common stock in exchange for
         100% of the issued and outstanding shares of Bayard. These amounts
         represent the conversion of each Bayard share into 0.3375 shares of
         Nabors common stock and $0.30 in cash. Nabors common stock was valued
         at $12.0625 per share, which represents the average market price of
         Nabors common stock for the two day period prior to the agreement as to
         the final merger terms. Additionally, the purchase price reflects the
         issuance by Nabors of 437,603 options and 133,988 warrants to purchase
         Nabors common stock, which were valued at their estimated fair market
         value using the Black-Scholes option pricing model, in exchange for the
         outstanding options and warrants of Bayard.
 
        The purchase price has been calculated as follows:

     (b) The purchase price including estimated acquisition costs have been
         allocated to assets acquired and liabilities assumed based upon their
         estimated fair values. The excess of the estimated fair value of the
         assets acquired and liabilities assumed over the purchase price has
         been accounted for as a reduction of the value assigned to property,
         plant and equipment.

                 CONDENSED FINANCIAL STATEMENTS -- (CONTINUED)
 
            (ii)  To eliminate Bayard's historical goodwill, as well as deferred
                  financing costs associated with the Bayard $100 million 11%
                  Senior Notes due 2005.
 
            (iii) To record debt premium based upon the estimated fair value of
                  the Bayard senior notes. The fair value of the Bayard senior
                  notes was estimated based on the present value of amounts to
                  be paid, discounted at a rate currently available to Bayard
                  for borrowings with similar terms and maturities.
 
            (iv)  To adjust deferred tax obligations for differences between the
                  financial statement basis (which has been decreased as
                  described in (b)(i) above) and the tax basis (which will not
                  be decreased because of the merger) of the assets acquired and
                  liabilities assumed in accordance with SFAS No. 109.
 
     (c) Depreciation and amortization is adjusted to reflect Nabors
         depreciation policy, as well as to reflect the reduction in the value
         assigned to property, plant and equipment and the elimination of
         goodwill previously recorded by Bayard.
 
     (d) Interest expense is adjusted to reflect both the amortization of the
         fair value premium and the elimination of the amortization of the
         deferred financing costs recorded on the Bayard senior notes issued on
         June 26, 1998.
 
     (e) Income tax expense is adjusted to reflect the tax effect of the pro
         forma adjustments, as well as to reflect the combined tax position of
         the pro forma combined companies.
 
     (f) For the calculation of diluted earnings per share, net income is
         adjusted to add back $4,075,000 and $5,554,000 for the nine months
         ended September 30, 1998 and the twelve months ended December 31, 1997,
         respectively, of after tax interest expense on the Nabors $172,500,000
         5% Convertible Subordinated Notes.
 
     (g) Assumes that 6,140,456 Nabors shares were exchanged for 100% of the
         Bayard shares at the beginning of the periods presented.
 
     (h) Represents the results of operations for Trend, Ward and Bonray prior
         to their acquisition by Bayard. These results have been included on a
         pro forma basis due to their significance to Bayard. Operations
         subsequent to the date of purchase of Trend, Ward and Bonray, on May 1,
         May 30 and October 16, 1997, respectively, are included in the Bayard
         historical results.

                 BAYARD 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 Bayard and related notes included elsewhere
in this document.
 
GENERAL
 
     Bayard is a leading provider of contract land drilling services to major
and independent oil and gas companies. Bayard was formed in December 1996
through a series of formation transactions that established Bayard as a regional
competitor with ten rigs. Since that time, Bayard has grown to operate the fifth
largest land drilling fleet in the United States with a total of 87 rigs, 73 of
which are currently being marketed. This growth is due primarily to, and
Bayard's operations have been significantly affected by, the following
transactions:
 
     - Trend Acquisition. In May 1997, Bayard completed the acquisition of Trend
       Drilling Co. and its 14 rigs for $18 million in cash and 250,000 shares
       of Bayard common stock.
 
     - Ward Acquisition. Also in May 1997, Bayard acquired the assets of Ward
       Drilling Company, Inc. including six rigs for $8 million in cash, 400,000
       shares of Bayard common stock and warrants to purchase an additional
       200,000 shares of Bayard common stock.
 
     - Bonray Acquisition. In October 1997, Bayard acquired Bonray Drilling
       Corporation from DLB Oil & Gas, Inc. for 3,015,000 shares of Bayard
       common stock. In the Bonray acquisition, Bayard acquired 13 rigs,
       including seven rigs with depth capacities of 15,000 feet or greater and
       two SCR rigs.
 
     - Oliver Acquisition. On January 9, 1998, Bayard purchased six additional
       rigs from R. T. Oliver Drilling, Inc. for approximately $14 million in
       cash. Bayard expects to refurbish and purchase complementary equipment,
       including drill pipe, for these rigs when market conditions warrant.
 
     - Individual Rig Acquisitions. In addition to the Trend, Ward, Bonray and
       Oliver acquisitions, Bayard has invested $5.5 million to acquire six rigs
       in five transactions involving purchases of individual rigs or rig
       components. These transactions are referred to in this document as the
       "individual rig acquisitions" and, together with the formation
       transactions and the Trend, Ward, Bonray and Oliver acquisitions, are
       referred to as the "consolidation transactions." In addition, Bayard has
       purchased one rig for approximately $54,000 and has one other rig, which
       may be assembled from inventoried components. In August 1997, Bayard sold
       one rig.
 
     - Initial Public Offering. In November 1997, Bayard completed an initial
       public offering of 11,040,000 shares of Bayard common stock. Bayard sold
       4,229,050 shares of Bayard common stock in its initial public offering
       and received net proceeds of $89.5 million.
 
     - Refurbishment. The consolidation transactions included a number of rigs
       in need of refurbishment. From January 1, 1997 through September 30,
       1998, Bayard completed refurbishment of 15 rigs at an average cost of
       approximately $2.7 million per rig, including drill pipe. These rigs were
       placed in service at various dates between January 1997 and June 1998. At
       September 30, 1998, Bayard had 14 additional rigs in various stages of
       refurbishment. Bayard recently revised its schedule for rig refurbishment
       as a result of changes in market conditions that have caused an
       industry-wide decrease in rig utilization. Bayard anticipates
       refurbishing and placing the remaining 14 rigs into service as market
       conditions warrant.
 
     - TransTexas Acquisition. In June 1998, Bayard completed the acquisition of
       25 drilling rigs and certain related equipment and other assets from
       TransTexas Gas Corporation for $75 million in cash. This transaction was
       financed through Bayard's senior notes offering.
 
     The historical financial results presented in this document include the
effects of the foregoing transactions and the operations of the related rigs
only for the periods after such transactions. In addition,
                                       59
<PAGE>   65
 
the historical financial results include periods in which a number of rigs were
being refurbished and did not contribute to revenues. Accordingly, Bayard does
not believe that the historical statements of operations presented in this
document are necessarily indicative of Bayard's future operating results, or
that comparisons of financial results between the periods presented in this
document are necessarily meaningful, particularly in light of the magnitude of
Bayard's recent acquisitions and rig refurbishment projects. This discussion and
analysis should be read in conjunction with the consolidated financial
statements of Bayard and notes to the financial statements included elsewhere in
this document and Bayard's Annual Report on Form 10-K for the year ended
December 31, 1997.
 
DOMESTIC LAND DRILLING INDUSTRY OVERVIEW
 
     Demand for Bayard's contract land drilling services is substantially
dependent upon, and affected by, the level of domestic oil and gas exploration
and development activity. Industry sources estimate that from its peak in 1982,
the supply of domestic rigs has fallen as a result of normal attrition,
cannibalization of components to refurbish rigs, the inability of smaller
competitors to raise capital needed to upgrade and modernize rigs and the export
of rigs to international markets. As a result of these factors, the contract
land drilling industry has been cyclical with significant volatility in
profitability and rig values.
 
     Bayard's operating margins are influenced by contract drilling rates,
operating costs and drilling rig utilization. Although Bayard believes that
improved technologies, the long-term decline in the supply of rigs and stable
oil and gas prices contributed to increased activity in the exploration and
production sector during 1997, there has been a general decline in oil and, to a
lesser extent, gas prices during 1998 and there can be no assurance that such
decline will not continue. This decline in oil and gas prices has contributed to
a decrease in Bayard's rig utilization rates from 88% for the fourth quarter of
1997 to 35% for the fourth quarter of 1998. There can be no assurance that oil
and gas prices will not continue to decline or that any such decline would not
have a material adverse effect on Bayard's utilization rates. In addition,
ongoing movement or reactivation of land drilling rigs, including the movement
of rigs from outside the United States into domestic markets, or new
construction of drilling rigs could increase rig supply and adversely affect
contract drilling rates and utilization levels. Bayard cannot predict the future
level of demand for its contract drilling services, future conditions in the
contract drilling industry or future contract drilling rates.
 
FINANCIAL CONDITION AND LIQUIDITY
 
     Since December 1996, Bayard has completed the consolidation transactions
and the TransTexas acquisition. Bayard's formation transactions involved the
issuance of an aggregate of 5,600,000 shares of Bayard common stock in
consideration for the contribution to Bayard of 16 rigs and $10 million in cash.
At the time of the formation transactions, Bayard entered into a $24 million
term loan facility with The CIT Group/Equipment Financing, Inc., principally for
the refurbishment of certain of Bayard's rigs. In May 1997, contemporaneously
with the Trend acquisition and in anticipation of the Ward acquisition, Bayard
completed a financing transaction in which it:
 
     - issued to Chesapeake Energy Corporation and Energy Spectrum Partners LP
       additional shares of Bayard common stock and two series of warrants
       together with Subordinated Notes due May 1, 2003 for $28.5 million in
       cash; and
 
     - increased the availability under its debt facilities from $24 million to
       $40.5 million.
 
     In November 1997, Bayard consummated its initial public offering, in which
Bayard registered the sale of an aggregate of 11,040,000 shares of Bayard common
stock. In the initial public offering, Bayard issued and sold 4,229,050 shares
of Bayard common stock and certain stockholders of Bayard sold 6,810,950 shares
of Bayard common stock. Bayard received net proceeds of $89.5 million for the
shares
 
                                       60
<PAGE>   66
 
sold by it in the initial public offering. Through December 31, 1998, these net
proceeds had been used as follows:
 
     - $50.1 million to purchase machinery and equipment;
 
     - $38.6 million to repay indebtedness; and
 
     - $817,125 to pay CIT in connection with the exercise of certain options to
       purchase Bayard common stock.
 
     Currently, Bayard's primary bank debt facilities consist of a term loan
under an agreement with CIT and Fleet Capital Corporation, under which $15.5
million was outstanding as of December 31, 1998, and a $10 million revolving
loan facility under a revolving loan agreement with Fleet, under which Bayard
has no outstanding borrowings other than approximately $1.3 million in letters
of credit as of December 31, 1998. The term loan agreement and the revolving
loan agreement are referred to in this document collectively as the "loan
agreements." On June 26, 1998, Bayard issued $100 million of its senior notes
and used $75 million of such proceeds to fund the TransTexas acquisition.
Further information regarding the loan agreements and Bayard's senior notes is
set forth below under "Financing Activities."
 
     Bayard's principal requirements for capital, in addition to the funding of
ongoing contract drilling operations, have been capital expenditures, including
the refurbishment of existing rigs and acquisitions. From December 1996 through
September 30, 1998, Bayard spent $20.7 million on the Trend acquisition, $11.9
million on the Ward acquisition, $35 million on the Bonray acquisition, $14
million on the Oliver acquisition, $5.5 million on the individual rig
acquisitions, approximately $106.8 million on refurbishments and other related
equipment purchases, including drill pipe, and $75 million on the TransTexas
acquisition. As a result, Bayard's net property and equipment increased from $27
million at December 31, 1996 to $155.7 million at December 31, 1997 and $283.7
million at September 30, 1998. Bayard's principal sources of liquidity have been
the issuance of Bayard common stock, its senior notes, its subordinated notes,
warrants to purchase Bayard common stock and borrowings under the loan
agreements. As of December 31, 1998, Bayard had $100 million principal amount of
its senior notes outstanding, $15.5 million of borrowings outstanding under the
term loan agreement, no borrowings outstanding under the revolving loan
agreement, no outstanding subordinated notes and $3 million of cash and cash
equivalents. Bayard expects to fund its capital requirements during the period
before the expected date of the merger through cash flow from operations, and,
to the extent required, borrowings under the loan agreements. Bayard believes
that such sources of funds will be sufficient to meet Bayard's anticipated uses
through the expected date of the merger. If the merger is not consummated or is
delayed for a significant period of time, Bayard may be required to seek
additional sources of funds to meet is capital requirements in 1999.
 
     The most significant change in Bayard's balance sheet from December 31,
1997 to September 30, 1998 was a $128 million increase in net property and
equipment, and the issuance of $100 million of senior notes. During this same
period, long-term debt, net of current maturities, decreased by $9.8 million and
stockholders' equity increased by $.8 million.
 
     From December 31, 1997 to September 30, 1998, Bayard's working capital
position decreased by $41.5 million to $7.4 million. This was primarily the
result of additions to fixed assets.
 
  Operating Activities
 
     During the year ended December 31, 1996, Bayard required $462,000 of cash
to fund operating activities. This was the result of $1.5 million of cash
provided by operations, partially offset by changes in working capital items
that required $2 million of cash. Cash required for changes in working capital
items included the following:
 
     - increase in accounts receivable of $2.1 million;
 
     - increase in other assets totaling $185,000; and
 
                                       61
<PAGE>   67
 
     - decrease of $383,000 in accounts payable, which were partially offset by
       an increase of $663,000 of other current liabilities.
 
     During the year ended December 31, 1997, net cash used in operating
activities totaled $1.3 million. Bayard generated cash from operations of $10.8
million and working capital changes used $12.1 million.
 
     During the nine months ended September 30, 1998, net cash provided from
operating activities totaled $23 million. Bayard generated cash from operations
of $11.5 million and working capital changes provided $11.5 million.
 
  Investing Activities
 
     During the year ended December 31, 1996, Bayard invested $21.7 million in
fixed assets, net of asset sales. The major components of these expenditures
were $10.4 million of cash expenditures to acquire and refurbish five diesel
electric SCR rigs and $9.8 million of Bayard common stock issued to acquire rigs
in the Formation Transactions.
 
     During the year ended December 31, 1997, Bayard invested $135 million in
fixed assets, including the Trend acquisition, the Ward acquisition, the Bonray
acquisition and the individual rig acquisitions. Rig refurbishments consisted of
$51.5 million, and $10.6 million was invested in drill pipe and other drilling
related equipment. The acquisitions of Trend, Ward, and Bonray were partially
funded through the issuance of Bayard common stock valued at $42.3 million.
 
     During the nine months ended September 30, 1998, Bayard invested $138
million in fixed assets, including $11.1 million in the Oliver acquisition, and
$75 million in the TransTexas acquisition. Rig refurbishment costs totaled $38.5
million, including the Oliver acquisition costs, refurbishments of $14.5 million
on rigs currently being marketed, and $13.5 million of equipment for future
refurbishment programs. Total investment in drill pipe was $12.8 million.
 
  Financing Activities
 
     During the year ended December 31, 1996, Bayard raised $15.9 million from
financing activities. Bayard borrowed $7 million during the year under the term
loan as described below. Bayard also issued 3,600,000 shares of Bayard common
stock for assets and cash and made debt payments totaling $900,000 during the
year.
 
     During the year ended December 31, 1997, Bayard obtained $132.1 million
from financing activities, including net borrowing under the loan agreements
totaling $25.8 million and $107.1 million from the issuance of Bayard common
stock. The proceeds from these transactions were used to fund Bayard's working
capital requirements and capital expenditures as discussed above.
 
     During the nine months ended September 30, 1998, Bayard's payments under
the loan agreements totaled $13.7 million.
 
     In April 1998, Bayard redeemed in full the $2.52 million principal amount
of subordinated notes issued to Energy Spectrum Partners LP together with
accrued interest of $47,740. In connection with the redemption, Energy Spectrum
Partners LP waived its rights to require Bayard to redeem the subordinated notes
at 110% of par value. This redemption, coupled with the redemption of $18.0
million principal amount of Bayard's subordinated notes from Chesapeake Energy
Corporation at the time of Bayard's initial public offering, leaves no
subordinated notes outstanding.
 
     On June 26, 1998, Bayard issued $100 million of senior notes and used $75
million of such proceeds to fund the TransTexas acquisition. Bayard intends to
use the remaining proceeds for general corporate purposes, possibly including
acquisitions of additional drilling rigs and related equipment and the
refurbishment of rigs. Bayard's senior notes mature on June 30, 2005. Interest
on Bayard's senior notes is payable semi-annually on June 30 and December 31 of
each year, commencing on December 31, 1998. The senior notes are not redeemable
before June 30, 2003, on or after which they will be redeemable, in
 
                                       62
<PAGE>   68
 
whole or in part, at the option of Bayard, at the redemption prices set forth in
the indenture relating to the senior notes, plus accrued and unpaid interest and
certain other charges, if any, thereon to the date of redemption. In addition,
at any time on or before June 30, 2001, Bayard may redeem up to 35% of the
original aggregate principal amount of its senior notes with the net proceeds of
certain qualifying equity offerings at a redemption price equal to 111% of the
principal amount of the senior notes, plus accrued and unpaid interest and
certain other charges, if any, thereon to the date of redemption, provided that
at least $65 million in aggregate principal amount of Bayard's senior notes
remains outstanding immediately after the occurrence of such redemption. Upon a
transaction resulting in a change of control, each holder of Bayard's senior
notes will have the right to require Bayard to repurchase all or any part of
such holder's senior notes at a price equal to 101% of the principal amount of
the senior notes, plus accrued and unpaid interest and certain other charges, if
any, thereon to the date of repurchase. Bayard's senior notes are senior
unsecured obligations of Bayard and rank pari passu in right of payment with all
existing and future senior indebtedness and other senior obligations of Bayard,
and senior in right of payment to all future subordinated indebtedness of
Bayard.
 
     Each of Bayard's wholly owned domestic subsidiaries has issued a guarantee
of Bayard's obligations under its senior notes. The guarantees are senior
unsecured obligations of each guarantor and rank pari passu in right of payment
with all other indebtedness and liabilities of such guarantor that are not
subordinated by their terms to other indebtedness of such guarantor, and senior
in right of payment to all subordinated indebtedness of such guarantor.
 
     Bayard had outstanding at September 30, 1998 $16.7 million of long term
debt under the term loan agreement. The term loan was incurred to finance the
purchase of certain land drilling rigs, the refurbishment of such rigs and
equipment and for working capital purposes. On May 14, 1998, in connection with
Bayard's corporate reorganization into a holding company structure:
 
     - Bayard prepaid $6.2 million of the term loan, obtained a release of all
       collateral for the term loan, except 12 drilling rigs and related
       equipment, and transferred to Bayard Drilling, L.P., Bayard's wholly
       owned operating subsidiary, substantially all of its assets, subject to
       such liens; and
 
     - Bayard Drilling, L.P. and Bayard Drilling, L.L.C., another wholly owned
       subsidiary of Bayard, agreed to guarantee the term loan.
 
Before such prepayment and collateral release, the term loan was secured by
substantially all of the assets of Bayard and Trend. In connection with Bayard's
senior notes offering, the term loan was further amended to add Bonray as a
guarantor of Bayard's obligations.
 
     The term loan agreement requires Bayard and its subsidiaries to maintain
collateral security for the term loan based on appraised fair market value and
orderly liquidation value of Bayard's drilling rigs and associated rig equipment
equivalent to the balance of the term loan, and adhere to specified cash flow,
leverage and liquidity ratios and minimum net worth and liquidity requirements.
The term loan agreement contains restrictions on, among other things, the
ability of Bayard and its subsidiaries to pay dividends, make investments, incur
indebtedness and liens, and make capital expenditures and requires the
maintenance of liquidity of $3 million through December 31, 1998. The term loan
agreement also contains affirmative covenants typical of secured loan
arrangements with finance companies, such as requiring financial reports,
insurance maintenance, legal, environmental and permit compliance. Bayard is
prohibited from prepaying the term loan until after December 31, 1999.
 
     The term loan bears interest at Bayard's choice of LIBOR plus 4.25% per
annum, 9.89% at September 30, 1998, or the prime rate of The Chase Manhattan
Bank plus 2.00% per annum and requires equal monthly payments of principal,
together with accrued interest, in amounts sufficient to repay borrowings at
maturity on March 31, 2002.
 
     The revolving loan agreement provides revolving credit loans, subject to a
borrowing base comprised of a portion of Bayard's accounts receivable, of up to
$10.0 million, $2.0 million of which is available for letters of credit, for
general corporate purposes. Bayard has not borrowed under the revolving loan
 
                                       63
<PAGE>   69
 
agreement since November 1997 but has approximately $1.3 million of letters of
credit outstanding under that agreement.
 
     Any borrowings under the revolving loan agreement would bear interest based
on Fleet National Bank's prime rate plus 1.5% or approximately 10.0% at
September 30, 1998. A portion of the proceeds from Bayard's initial public
offering was used to repay all outstanding amounts under the revolving loan
agreement. Bayard pays certain fees under the revolving loan agreement,
including a commitment fee equal to 0.5% of the unused portion of the maximum
commitment. Fleet's commitment to lend under the revolving loan agreement ends
in April 2000. Bayard may terminate the revolving loan agreement upon 60 days'
prior written notice to Fleet and the payment of a termination fee of 2% of the
facility.
 
     The revolving loan agreement is collateralized by certain assets of Bayard
and Trend that were transferred to Bayard Drilling, L.P. during Bayard's
corporate reorganization into a holding company structure, including accounts
receivable, certain equipment and inventory, Bayard's El Reno, Oklahoma yard and
the same 12 drilling rigs that collateralize the term loan agreement, together
with equipment and drilling contracts related to such rigs. The revolving loan
agreement is also secured by the receivables and certain other assets of Bayard,
Bayard Drilling, L.P., Bayard Drilling, L.L.C., Trend and Bonray. Until May 14,
1998, the revolving loan agreement was also collateralized by all drilling rigs
of Bayard and Trend, upon which date Fleet released all but such 12 rigs and
related assets. Bayard Drilling, L.P., Bayard Drilling, L.L.C., Trend and Bonray
have agreed to guarantee the obligations under the revolving loan agreement. The
revolving loan agreement contains customary restrictive covenants that are
substantially similar to the covenants contained in the term loan agreement.
 
     Bayard also has issued three amortizing term notes, referred to as the "top
drive notes," totaling approximately $2.5 million outstanding at September 30,
1998. This debt bears interest at 9.5% per annum and is collateralized by
certain top drive equipment of Bayard and letters of credit in amounts totaling
approximately $700,000. The debt represented by the top drive notes matures in
July, October and November of 2000. The note agreement relating to the top drive
notes does not contain any restrictive financial covenants but contains a cross
default to the term loan agreement and the revolving loan agreement.
 
  Recent Events
 
     In December 1998 and January 1999, Nabors purchased from Bayard several
components of drilling equipment in exchange for promissory notes in the
aggregate principal amount of approximately $457,000.
 
RESULTS OF OPERATIONS
 
     Comparisons of Bayard's results of operations are set forth below for the
periods identified. As used in the following tables and the related discussion:
 
     - Rig days worked represents the number of rigs being marketed by Bayard,
       multiplied by the number of days during which such rigs are being
       operated, mobilized, assembled or dismantled while under contract. Rig
       days are a common measurement of both utilization rates and fleet size.
 
     - Average revenues per day and per day revenues represent total contract
       drilling revenues, including mobilization revenues and reimbursement for
       fuel and other costs, divided by the total number of rig days worked by
       Bayard's drilling fleet marketed during the period.
 
     - Drilling costs exclude depreciation and amortization and general and
       administrative expenses.
 
     - Average costs per day represent direct operating costs divided by the
       total number of rig days worked by Bayard's drilling fleet marketed
       during the period.
 
     - Average margin per day represents the difference between average revenues
       per day and average costs per day.

     Drilling revenues increased approximately $31.6 million, or 95% to $64.8
million for the nine months ended September 30, 1998, from $33.2 million for the
nine months ended September 30, 1997. This revenue increase was the result of a
4,489 day, or 79%, increase in rig days worked, and a $491, or 8.4%, increase in
the average revenue per day. The increase in days worked was a result of an
increase in the average number of rigs owned and available for service. As of
September 30, 1998, Bayard had 73 rigs available for service. The increase in
rigs available for service was principally the result of the consolidation
transactions. Rig days worked consisted of 2,293 days in the Gulf Coast region,
7,401 days in the Mid-Continent region, and 484 days in the South Texas region.
Increases in revenues per day were a result of the increase in the day rates and
the average number of land drilling rigs being marketed by Bayard, offset by a
decrease in the average utilization rate from 96% to 65%.
 
     Drilling costs increased by approximately $24.2 million, or 100%, to $48.4
million for the nine months ended September 30, 1998, from $24.2 million for the
nine months ended September 30, 1997. The increase in drilling operating
expenses was a direct result of the increase in the number of rigs owned and
available for service and the corresponding 4,489 day increase in the days
worked.
 
     Bayard's operating margin increased by approximately $7.4 million, or 82%,
to $16.4 million for the nine months ended September 30, 1998, as compared to $9
million for the nine months ended September 30, 1997. The increase in operating
margin resulted from the increase in the average revenue per day and the
increase in days worked.
 
     Depreciation and amortization expense increased by $5.4 million, or 110%,
to $10.4 million for the nine months ended September 30, 1998, as compared to
$4.9 million for the nine months ended September 30, 1997. The increase was
primarily the result of additional depreciation associated with the
consolidation transactions.
 
     General and administrative expense increased by $1.2 million, or 101%, to
$2,374,000 for the nine months ended September 30, 1998, from $1,181,000 for the
same period of 1997. This increase was primarily attributable to increased
payroll costs associated with new management and increased corporate staff and
increased legal fees from Bayard's acquisition activities and public status.
 
     Interest expense was $3.4 million for the nine months ended September 30,
1998 as compared to $2.2 million for the nine months ended September 30, 1997.
This increase was primarily attributable to Bayard's senior notes.

     Other income increased for the nine months ended September 30, 1998 as
compared to the nine months ended September 30, 1997. This increase was
primarily attributable to interest income received on funds being invested in
short-term investments and the gain recognized on the sale of assets.
 
     For the nine months ended September 30, 1998, the income tax provision was
$758,000 compared to $410,000 for the first nine months of 1997. The increase in
pretax income for the first nine months of September 1998 versus the first nine
months of 1997 caused this increase.
 
     For the nine months ended September 30, 1998, Bayard recorded an
extraordinary loss in the amount of $338,000, net of income taxes of $245,000,
from the early extinguishment of certain subordinate debt in the amount of
approximately $2.5 million, and from the payment on term notes in the amount of
$6.2 million using proceeds from Bayard's initial public offering.

     Drilling revenues increased approximately $46.0 million, or 469%, to $55.7
million for the year ended December 31, 1997, from $9.8 million for the year
ended December 31, 1996. This revenue increase was the result of a 7,450 day, or
367%, increase in rig days worked, and a $1,055, or 22%, increase in the average
revenue per day. The increase in days worked was a result of an increase in the
average number of rigs owned and available for service. As of December 31, 1997,
Bayard had 49 rigs available for service. The increase in rigs available for
service was principally the result of the acquisitions consummated during the
year. Rig days worked consisted of 3,672 days worked in the Gulf Coast region
and 5,807 days worked in the Mid-Continent region. Increases in revenues per day
were a result of the overall increase in demand for land drilling rigs as
reflected in the utilization rate increase from 89% to 93%.
 
     Drilling costs increased by approximately $33.1 million, or 432%, to $40.7
million for the year ended December 31, 1997, as compared to $7.7 million for
the year ended December 31, 1996. The increase in drilling operating expenses
was a direct result of the increase in the number of rigs owned and available
for service and the corresponding 7,450 day increase in the days worked.
 
     Depreciation and amortization expense increased by $6.8 million, or 605%,
to $7.9 million for the year ended December 31, 1997, as compared to $1.1
million for the year ended December 31, 1996. The increase primarily reflects
additional depreciation associated with the acquisitions consummated during the
year.
 
     General and administrative expense increased by $1.2 million, or 184%, to
$1.9 million for the year ended December 31, 1997, from $658,000 for the same
period of 1996. This increase was primarily attributable to increased payroll
costs associated with new management and increased corporate staff and increased
professional fees due to Bayard's acquisition activities.
 
     Interest expense increased to $3.1 million for the year ended December 31,
1997 from $11,000 for the year ended 1996. This expense increased because
Bayard's outstanding debt increased during 1997.

</TABLE>
 
     Drilling revenues increased approximately $2.4 million, or 32%, to $9.8
million for the year ended December 31, 1996 from $7.4 million for the year
ended December 31, 1995. This improvement was the net result of an increase in
the number of rig days worked offset by a decrease in the average revenue per
day. Rig utilization also improved from 86% to 89% in 1996, because the contract
drilling market improved overall.
 
     Drilling costs increased by $1.6 million, or 26%, to $7.7 million for the
year ended December 31, 1996, from $6.1 million for the year ended December 31,
1995. This increase resulted primarily from increased utilization and, to a
lesser extent, increased direct labor costs.
 
     Depreciation and amortization expenses increased by $335,000, or 42%, to
$1.1 million for the year ended December 31, 1996 from $791,000 for the year
ended December 31, 1995. The increase in depreciation expense was primarily
attributable to acquisition and refurbishment costs.
 
     General and administrative expenses decreased by $222,000 to $658,000 for
the year ended December 31, 1996, from $880,000 for the year ended December 31,
1995. This decrease occurred because Bayard discontinued allocation of expenses
associated with the predecessor company.
 
     Interest expense remained fairly constant for the year end December 31,
1996, primarily as a result of the outstanding debt level remaining fairly
constant. Interest rates during these periods remained relatively unchanged.
 
     Other income increased $197,000 from 1995 to 1996, primarily as a result of
a loss recorded in 1995 in connection with the sale of certain assets.
 
     Bayard's income tax expense of $163,000 in 1996 was attributable to
Bayard's profitable operations.
 
     Bayard had net income of $267,000 in 1996 as compared to a net loss of
$222,000 in 1995. Bayard's net loss in 1995 includes net losses from the sale of
assets, for which there was no similar transaction in 1996.
 
RECENT OPERATING RESULTS
 
     Based upon currently available information, Bayard estimates that its total
revenues for the three months ended December 31, 1998 will be approximately 30%
lower than its total revenues for the three months ended September 30, 1998.
Bayard believes that this projected decline in revenues is attributable
principally to the decrease in the rig utilization rate from 65% for the three
months ended September 30,
 
                                       67
<PAGE>   73
 
1998 to 35% for the three months ended December 31, 1998. In addition, primarily
as a result of the foregoing factors, Bayard estimates that its net loss before
extraordinary items for the three months ended December 31, 1998, which includes
approximately $700,000 in merger-related costs, will exceed by more than 250%
its net loss before extraordinary items for the three months ended September 30,
1998.
 
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.
 
YEAR 2000 COMPUTER ISSUES
 
     Background. The Year 2000 problem, commonly referred to as the "Y2K"
problem, is the product of a longstanding practice in the computer industry that
permitted the use of only two digits, rather than four, to define yearly dates.
This abbreviation of dates makes it impossible for certain computer systems and
other equipment with embedded microchips or processors, referred to collectively
as "business systems," to distinguish between centuries for a given date. For
example, a business system affected by the Y2K problem would be unable to
distinguish between 1898 and 1998: it would read both as simply "98." Not even
technology experts know with certainty what will happen on January 1, 2000 to
those business systems affected by the Y2K problem. Some anticipate such
business systems to revert to "00," recognizing the date as January 1, 1900.
This could cause miscalculations which could, in turn, disrupt operations, delay
payments or, in extreme conditions, disable those business systems entirely. In
addition, the potential exists for a "cascade effect" in which the problems of
suppliers, customers and other business partners impact the performance of
companies which have already addressed their own Y2K issues. Any or all of these
events could have a material adverse effect on a company's business, financial
condition or results of operations.
 
     Before December 31, 1999, Bayard intends to address any Y2K issues in its
significant business systems and to develop contingency plans for Y2K
disruptions. Bayard has begun an internal Y2K review to meet these goals.
Certain employees of Bayard, assisted by professional consultants, are
conducting this assessment of Bayard's computer systems and operations
infrastructure. Bayard has not hired any new employees specifically to address
Bayard's internal Y2K issues. This assessment should help Bayard determine what
actions are necessary to minimize any business disruptions or other liabilities
related to the Y2K problem.
 
     Y2K Readiness Assessment. Bayard is currently assessing its Y2K readiness
through a plan designed to accomplish the following:
 
     - identify and inventory Y2K problems in significant business systems;
 
     - assign the highest priority to Y2K business systems identified as
       critical for continuing operations;
 
     - assess other Y2K risks;
 
     - resolve and correct Y2K problems with repairs, upgrades, or replacements
       as necessary;
 
     - test any Y2K repairs, upgrades or replacements;
 
     - conduct Y2K surveys of significant customers, suppliers and other key
       business associates; and
 
     - develop and test Y2K contingency plans.
 
Bayard believes that this Y2K readiness assessment will enable it, before
January 1, 2000, to replace, upgrade or modify any critical business system
affected by the Y2K problem.
 
                                       68
<PAGE>   74
 
     In 1997, Bayard implemented new accounting, payroll and personnel software.
As part of the software purchase agreement, the software vendors agreed to
ensure that their software would be free from Y2K problems. Certain of these
vendors are currently correcting or upgrading their software in keeping with
this pledge. Bayard replaces existing computer hardware with new technology as
needed as a part of its normal business operations. Bayard believes that the Y2K
problem will not have a material adverse effect on its existing computer
hardware; however, Bayard is currently testing its hardware to ensure such
compliance.
 
     As part of its readiness assessment, Bayard is performing an inventory of
each drilling rig's critical business systems. Although Bayard believes that a
majority of its rigs are Y2K-compliant, until finalization of this inventory and
assessment, Bayard will not be able reasonably to assess a likely worst case Y2K
scenario for its drilling rigs. Bayard expects to define such scenario and
establish an appropriate contingency plan following the completion of its
readiness assessment.
 
     Bayard's key business associates include suppliers, who provide essential
capital equipment for the drilling rigs, and customers, who provide Bayard's
source of revenue and cash flow. If Y2K problems with a supplier delay the
purchase of essential equipment, Bayard's rigs could experience idle time
resulting in loss of revenue. Similarly, a customer's Y2K disruption could slow
Bayard's revenue stream, adversely impacting Bayard's cash flow, results of
operations and financial position. Bayard has sought Y2K readiness assurances
from these key business associates. These assurances are intended to aid Bayard
in determining the extent to which the failure of the key business associates to
correct their own Y2K problems could affect Bayard. While some of Bayard's key
business associates have assured Bayard that they are addressing their Y2K
problems, Bayard cannot guarantee that its key business associates will resolve
their Y2K problems in a timely manner; nor can Bayard inspect the Y2K efforts of
these key business associates or independently verify their representations. In
addition, Bayard cannot predict the effect on its business operations of the
failure of systems owned by others, of the delivery of inaccurate information
from other companies, or of the inability of others' systems to interface with
Bayard's systems. Bayard is in the process of assessing these risks; however,
Bayard cannot guarantee that another company's failure to resolve its own Y2K
problems would not materially and adversely affect Bayard.
 
     Costs. Bayard is funding the costs of its Y2K compliance efforts with cash
flows from operations. The ability of Bayard and certain software vendors
successfully to identify and repair or replace critical business systems
affected by the Y2K problem will greatly influence the total Y2K costs. Based
upon its assessment to date, Bayard does not expect the total Y2K costs to
differ substantially from Bayard's normal, recurring costs for systems
development, implementation and maintenance. Thus, Bayard does not expect these
costs to have a material adverse effect on Bayard's overall results of
operations or cash flows.
 
     Contingency Plans. Bayard does not yet have a comprehensive contingency
plan with respect to the Y2K problem. However, Bayard intends to establish such
a plan as part of its Y2K readiness assessment during 1999.
 
     Risks. Bayard is currently unable to predict with certainty the exact risk
which Y2K problems would pose to its operations in a reasonably likely worst
case scenario. Bayard's assessment of the impact of Y2K problems, as discussed
above, is based on Bayard management's understanding and best estimates at the
present time and could change substantially with a change in circumstances. For
example, the inability of key business associates to remedy external Y2K
problems or the failure of Bayard's software vendors to identify or repair
internal Y2K problems could adversely affect Bayard's performance. Thus,
successful avoidance of Y2K issues depends on many factors, some of which are
outside of Bayard's control and some of which are unknown at this time. Bayard
cannot assure that it will not experience any disruptions or other adverse
effects from Y2K problems despite expending reasonable efforts to avoid them.
While Bayard presently does not expect any catastrophic failures of any of its
business systems, it cannot assure that such failures will not occur. No one
should rely on statements to the contrary. These assessments are based upon
numerous assumptions as to future events and, as such, there can be no guarantee
that these estimates and predictions will prove accurate.

                               BUSINESS OF BAYARD
 
GENERAL
 
     Bayard is a leading provider of contract land drilling services to major
and independent oil and gas companies. As of December 31, 1998, Bayard's rig
fleet consisted of 87 rigs, of which 73 were being marketed and 14 were
available for refurbishment. For the three months ended September 30, 1998,
Bayard experienced an overall utilization rate of approximately 48% for its
marketed rigs.
 
     Bayard's fleet consists primarily of rigs capable of deep drilling
applications to well depths of 15,000 feet or greater. Bayard believes that new
technologies, including three-dimensional seismic techniques, increasingly
accurate down hole measurement devices and improved guidance systems and
directional drilling motors for horizontal and directional wells, have made deep
drilling targets more attractive to oil and gas companies. Of Bayard's 87 rigs,
69 are capable of drilling to depths of 15,000 feet or greater and 43 are
capable of drilling to depths of 20,000 feet or greater. Bayard's large
percentage of SCR rigs, comprising 31 of its 87 rigs, positions Bayard's fleet
as one of the most technically advanced in the industry.
 
     Bayard was formed in December 1996 as the successor to Anadarko Drilling
Company, which owned ten rigs. Through December 31, 1998, Bayard had acquired 77
additional rigs, net of sales. Many of the acquired rigs were put into service
in the later months of 1997 and therefore did not contribute significantly to
operating results in 1997.
 
CORE OPERATING AREAS
 
     Bayard's rig fleet is currently concentrated in three core operating
regions -- the Mid-Continent region, the Gulf Coast region and the South Texas
region. Bayard is among the largest rig suppliers in each of these regions.
 
  Mid-Continent Region
 
     The Mid-Continent region is comprised principally of Oklahoma, North Texas
and the Texas Panhandle. At December 31, 1998, Bayard had 39 rigs marketed in
the Mid-Continent region and was the most active drilling contractor in the
region. Bayard's rigs operated in the Mid-Continent region are generally capable
of drilling to depths of 10,000 feet or greater and are marketed by Bayard to
meet the specific well depths and mobility needs of producers in that region. At
December 31, 1998, 122 rigs were being utilized in this region, making it the
most active domestic onshore drilling market at that time. This area is
characterized by well-defined target formations and long-lived natural gas
reserves.
 
  Gulf Coast Region
 
     The Gulf Coast region is comprised of the onshore Gulf of Mexico areas in
Texas, Louisiana, Mississippi and Alabama. At December 31, 1998, Bayard had 13
rigs marketed in the Gulf Coast region, including 12 diesel electric SCR rigs.
Bayard believes that its high quality equipment, including diesel electric SCR
rigs, powerful mud pumps and high horsepower drawworks, give Bayard a
competitive advantage in attracting premium jobs with customers engaged in
multi-well drilling programs in this region. At December 31, 1998, 79 rigs were
being utilized by Bayard and others in this region, making it the fourth most
active domestic onshore drilling market at that time. The Gulf Coast region is
characterized by significant drilling activity in deep, technically challenging
formations for which Bayard's SCR and deep mechanical rigs are particularly well
suited. While recent results in certain areas of the Gulf Coast have been
disappointing to producers, most notably the Austin Chalk formation in Louisiana
and the Pinnacle Reef in Texas, significant exploration and development activity
is ongoing.

  South Texas Region
 
     The South Texas region is comprised of the southern portion of onshore
Texas. Bayard added South Texas as its third core operating region in June 1998
as a result of the TransTexas acquisition, in which it acquired 25 rigs
previously operated by TransTexas in the South Texas region. At December 31,
1998, Bayard had 21 rigs being marketed in the South Texas region and four rigs
available to be refurbished as market conditions warrant. The TransTexas rigs
acquired by Bayard had been utilized historically only to meet the internal
drilling requirements of TransTexas. With the completion of the TransTexas
acquisition, Bayard began to actively market the acquired rigs not being
utilized by TransTexas under an alliance agreement between Bayard and
TransTexas. At December 31, 1998, 93 rigs were being utilized by Bayard and
others in this region, making it the third most active domestic onshore drilling
market at that time. The South Texas region is predominately a gas producing
region, and, accordingly, its drilling activity levels are less sensitive to
declining oil prices. Bayard believes that its rigs operating in this region are
well suited for the mobility, drilling flexibility and hydraulic efficiency
required for this region's drilling applications.
 
BUSINESS STRATEGY
 
     Bayard believes that growth in earnings and cash flow can be achieved by
pursuing the following business strategy:
 
  Operating a Technologically Advanced Rig Fleet
 
     Bayard has assembled its existing rig fleet, and will pursue further
acquisitions, with the goal of operating one of the most technologically
sophisticated land drilling fleets in the United States. Many of Bayard's rigs
include engines, pumps and drilling mud systems that represent the best drilling
technology available and that Bayard believes offer greater efficiencies for
customers than many of the rigs available from its competitors. For example, by
deploying its diesel electric SCR rigs with two or three high horsepower pumps
and top drive drilling systems in challenging deep and horizontal drilling
situations, Bayard believes that it can reduce its customers' overall drilling
costs, thus securing and enhancing its relationships with some of the most
active operators in the domestic market. Bayard is committed to making the
capital investments required to maintain and, in appropriate circumstances,
increase the technological sophistication and operational efficiencies of its
fleet.
 
  Developing Deep Drilling Capabilities
 
     Bayard believes there is greater demand for rigs capable of drilling
deeper, more complex wells, including 1,500 horsepower and larger rigs, and has
focused, and will continue to focus, on acquiring rigs with these capabilities.
Of the 25 TransTexas rigs, 12 are 1,500 horsepower or larger rigs and an
additional 10 are 1,000 horsepower or larger rigs. At December 31, 1998, 78% of
Bayard's rig fleet was capable of drilling to 15,000 feet or greater. Management
believes that demand and utilization rates for these types of rigs, particularly
SCR rigs, will remain higher than for rigs with lesser depth capacities because
the deep drilling rigs provide greater operational flexibility and efficiency.
 
  Focusing on Core Markets
 
     Bayard believes that its strong asset position and operating expertise in
the Mid-Continent and Gulf Coast regions enable it to achieve operating
efficiencies and to provide premium service to its customers in these markets.
Bayard is the largest provider of drilling rigs in Oklahoma and is among the
largest operators of deep rigs in the onshore Gulf Coast region. As a result of
the TransTexas acquisition, Bayard is one of the largest suppliers of drilling
rigs in South Texas, positioning Bayard to mobilize additional rigs in that
region as market conditions warrant.

  Developing and Maintaining Relationships with Operators
 
     In order to maximize the utilization rate of its rig fleet and to minimize
exposure to market downturns, Bayard seeks to maintain and build relationships
with operators committed to active domestic drilling programs. Bayard's largest
current customers include Apache Corporation, Chesapeake Energy Corporation,
Enron Oil and Gas Company, Marathon Oil Company, Sonat Exploration Company and
Union Pacific Resources Corporation. Each of these companies was among the most
active onshore operators in the United States during the last three years.
Bayard has entered into an alliance agreement with TransTexas by which Bayard
will make up to 15 rigs available to TransTexas to meet its drilling
requirements, if any, in an area that includes, among others, the South Texas
and Gulf Coast regions. During the nine months ended September 30, 1998, the
three largest customers for Bayard's contract drilling services were Chesapeake,
Union Pacific Resources and Sonat Exploration, which accounted for approximately
14%, 10% and 10% of total revenues, respectively.
 
  Acquiring and Refurbishing Additional Rigs and Related Equipment
 
     Bayard intends to pursue selective acquisitions of additional rigs and
related equipment, including top drive drilling systems, subject to the
limitations on acquisitions set forth in the merger agreement. Additionally,
Bayard has experience in the acquisition of component parts from which rigs can
be assembled or refurbished and intends to continue to seek similar
opportunities for the expansion and enhancement of its rig fleet by such means.
Since its formation and through December 31, 1998, Bayard had acquired 77 land
rigs, net of sales, in eleven transactions.
 
DRILLING EQUIPMENT AND SUPPLIES
 
     A land drilling rig consists of various components, including engines,
drawworks, a derrick or mast, substructure, pumps to circulate drilling fluid,
blowout preventers, drill pipe and related equipment. The actual drilling
capacity of a rig may be more or less than its rated drilling capacity. Numerous
factors, including the length of a rig's drill pipe and the drilling conditions
of any particular well can cause this variance. The intended well depth and the
drill site conditions determine the rig, drill pipe length and other equipment
needed to complete a well. Bayard's rigs can be relocated to areas where demand,
well specifications and day rates allow for maximization of gross operating
margins and utilization. Generally, land rigs operate with crews of five to six
persons.
 
     As of December 31, 1998, Bayard's fleet included 31 rigs that are diesel
electric SCR rigs and 56 that are mechanical rigs. Mechanical rigs utilize
diesel engines to produce power that is transferred to drilling equipment, such
as drawworks and pumps, by way of a compound consisting of a series of chains,
sprockets and pneumatic clutches. SCR rigs employ diesel engines that generate
alternating current electricity which is converted and transferred into amps as
alternating current or direct current electricity, which in turn drives electric
motors powering the drilling equipment. Bayard believes that SCR rigs offer a
number of advantages over mechanical rigs. SCR rigs enable flexible power
distribution to selected individual drilling equipment components, providing for
more precise drilling control and efficient operation. SCR rigs are also quieter
and safer because the diesel engines are typically located away from the rig
floor and well bore, allowing for better communication among rig crews. SCR rigs
are also more easily adapted to the use of top drive drilling systems which are
typically electrically powered. Bayard has developed a fleet that uses the
advanced drilling technology of diesel electric SCR rigs to provide greater
efficiencies to its customers, especially in deep drilling, horizontal and
directional applications, and uses mechanical rigs primarily in areas such as
the Mid-Continent region where operators target shallower well depths and
require more frequent mobility.
 
     In addition to its SCR rigs, Bayard has focused its acquisitions on rigs
with efficient and flexible drilling mud systems as well as high horsepower
drawworks and mud pumps, features which give Bayard a competitive advantage in
attracting premium jobs with customers engaged in multi-well horizontal drilling
programs. The majority of Bayard's rigs employ diesel engines manufactured by
Caterpillar, Inc. as the rigs' main power sources. Bayard believes that such
engines are lighter and more fuel efficient than other
 
                                       72
<PAGE>   78
 
available engines, thus saving Bayard and its customers money in terms of lower
trucking costs and reduced fuel consumption.
 
     Finally, Bayard has begun equipping certain of its deep drilling rigs with
top drive drilling systems. Top drives provide Bayard's customers with greater
control in transferring horsepower to the bit, precise orientation of drilling
tools while drilling complex directional wells, and reduced incidence of stuck
drill pipe in high risk areas. Moreover, top drives enable the contractor to
drill in 90 foot sections rather than conventional 45 foot sections, a
capability which reduces connection time, and are safer for rig employees and
equipment during tubular handling operations and in well control situations.
Currently, Bayard has five rigs equipped with top drives and has purchased one
additional top drive.
 
RIG FLEET
 
     The following table identifies certain information as of December 31, 1998
regarding the rigs owned and operated by Bayard. In this table, rigs identified
as "SCR" are diesel electric silicon controlled rectifier rigs and rigs
identified as "Mechanical" are mechanical rigs powered by diesel engines.
Drawworks horsepower represents the amount of input power required to achieve
the maximum hoisting capability of the rig's drawworks, while total horsepower
represents the maximum horsepower produced by a rig's diesel engines for
consumption by the drilling equipment. The five rigs in the Gulf Coast and
Mid-Continent regions identified with an asterisk (*) are equipped with National
PS350/500 top drives.

     Drilling rigs and related equipment deteriorate over time unless they are
operated and maintained properly. Bayard strives to keep its drilling rigs well
maintained and technologically competitive. An active maintenance program during
the life of a drilling rig permits the maintenance, replacement and upgrading of
its components on an individual basis. Over the life of a typical drilling rig,
major components, such as
 
                                       74
<PAGE>   80
 
engines, pumps, drawworks and drill pipe, are replaced or rebuilt on a periodic
basis as required while other components, such as the mast and substructure, can
be utilized for extended periods of time with proper maintenance.
 
     In connection with the TransTexas acquisition, Bayard acquired 45 trucks
which have been utilized to move Bayard's drilling rigs and related equipment.
The fleet includes various types of trucks, including pole, winch, tandem and
hauling vehicles. Additionally, Bayard acquired approximately 60 lowboy and
float trailers, three cranes and three forklifts.
 
     During periods of high utilization in recent years, there has been a
general shortage of certain drilling equipment and supplies used in Bayard's
business. Except for limited periods of high utilization, the land drilling
industry has generally been characterized by an oversupply of land rigs.
Therefore, rig manufacturers have generally focused on the production of more
expensive offshore rigs and rig equipment. As a result, most rig manufacturers
are not currently building new land rigs and those manufacturers that are
building new land rigs and components charge premium prices, approximately $13.0
million for a new 2,000 horsepower rig, and require that orders be placed at
least 120 days in advance of requested delivery. The limited availability of new
rigs and equipment has caused land rig owners and operators, including Bayard,
to maintain and enhance their fleets primarily through acquisitions and
refurbishments using previously manufactured rig components and equipment. As
the land drilling industry continues to refurbish rigs using existing components
and equipment, the available supply of such components and equipment continues
to deplete. Additionally, a shortage of drill pipe in the contract drilling
industry has caused the price of drill pipe to increase significantly over the
past two years. Bayard has established arrangements to meet its current needs
for certain necessary drilling equipment and supplies, including drill pipe, on
satisfactory terms, but there can be no assurance that it will continue to be
able to do so. Accordingly, there can be no assurance that Bayard will not
experience shortages of, or material price increases in, drilling equipment and
supplies, including drill pipe, in the future. Any such shortages could delay
and adversely affect Bayard's ability to refurbish its construction project rigs
and obtain contracts for its marketed rigs.
 
CONTRACT DRILLING OPERATIONS
 
     Bayard's drilling rigs are employed under individual contracts which extend
either over a stated period of time or the time required to drill a well or a
number of wells. Drilling contracts are obtained through either a competitive
bidding process or as a result of direct negotiations with customers. Terms of
Bayard's drilling contracts vary based on factors such as the complexity and
risk of operations, on-site drilling conditions, type of equipment used and the
anticipated duration of the work to be performed. Contracts are typically
entered into on a single well basis and obligate Bayard to pay certain operating
expenses, including wages of drilling personnel, maintenance expenses and costs
for incidental rig supplies, equipment and local office facilities. Contracts
generally are subject to termination by the customer on short notice, but are
sometimes written on a firm basis for a specified number of wells or years.
Bayard has ongoing relationships with a number of customers that often engage a
specific rig for the drilling of consecutive wells.
 
     At December 31, 1998, all of Bayard's working rigs were operating under
daywork contracts. In addition, Bayard and its predecessors in the past have
performed drilling services under footage and turnkey contracts and Bayard may
do so again in the future. Revenues from daywork contracts accounted for
approximately 98% and 95% of total drilling revenues, excluding mobilization
revenues, during the year ended December 31, 1997 and the nine months ended
September 30, 1998, respectively, with the remainder from footage and turnkey
contracts.
 
     Daywork Contracts. Under daywork contracts, Bayard provides a drilling rig
with required personnel to the operator, who supervises the drilling of the
well. Bayard is paid based on a negotiated fixed rate per day while the rig is
utilized. The rates for Bayard's services depend on market and competitive
conditions, the nature of the operations to be performed, the duration of the
work, the equipment and services to be provided, the geographic area involved
and other variables. Lower rates may be paid when the rig is in
 
                                       75
<PAGE>   81
 
transit, or when drilling operations are interrupted or restricted by equipment
breakdowns, actions of the customer or adverse weather conditions or other
conditions beyond the control of Bayard. In addition, daywork contracts
typically provide for a lump sum fee for the mobilization and demobilization of
the drilling rig. 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 Bayard generally bears no part of the usual capital risks,
such as time delays for stuck drill pipe and blowouts, associated with oil and
gas exploration.
 
     Footage and Turnkey Contracts. Under footage contracts, Bayard is paid a
fixed amount for each foot drilled, regardless of the time required or the
problems encountered in drilling the well. Bayard pays more of the out-of-pocket
costs associated with footage contracts compared to daywork contracts. Under
turnkey contracts, Bayard contracts to drill a well to an agreed depth under
specified conditions for a fixed price, regardless of the time required or the
problems encountered in drilling the well. Bayard 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 Bayard under footage and turnkey contracts are substantially
greater than under daywork contracts because Bayard 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, lost or damaged drill
pipe, machinery breakdowns, abnormal drilling conditions and risks associated
with subcontractors' services, supplies, cost escalation and personnel.
 
CUSTOMERS AND MARKETING
 
     Bayard's customers include major oil companies and independent oil and gas
producers. During the nine months ended September 30, 1998, the three largest
customers for Bayard's contract drilling services were Chesapeake Energy
Corporation, Union Pacific Resources Corp. and Sonat Exploration Company, which
accounted for approximately 14%, 10% and 10% of total revenues, respectively.
Chesapeake announced in 1997 that it was reducing its drilling program in the
Gulf Coast region, an area in which it utilizes a number of Bayard's rigs. In
late 1997, Chesapeake released two rigs under contract with Bayard and has
subsequently released three additional rigs it was using in the Gulf Coast
region. As of December 31, 1998, Chesapeake was utilizing four of Bayard's rigs;
however, there can be no assurance that Chesapeake or any of Bayard's other
principal customers will continue to employ Bayard's services or that the loss
of any of such customers or adverse developments affecting any of such customers
would not have a material adverse effect on Bayard's financial condition and
results of operations.
 
     Bayard enters into informal, nonbinding commitments with many of 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 Bayard nor the customer is legally required to
honor these commitments, Bayard strives to satisfy such commitments in order to
maintain good customer relations.
 
     Bayard's sales force consists of industry professionals with significant
land drilling sales experience who utilize industry contacts and available
public data to determine how to most appropriately market available rigs.
 
     Chesapeake Drilling Agreements. In December 1996, in connection with
Bayard's formation transactions, Chesapeake Energy Corporation and its operating
subsidiary entered into drilling agreements with Bayard by which Chesapeake
agreed to engage six of Bayard's rigs for two-year terms. For the year ended
December 31, 1997, Bayard recognized aggregate revenues of $10.9 million from
the Chesapeake drilling agreements.
 
     Under the terms of the Chesapeake drilling agreements, the standard day
rates were subject to upward, but not downward, adjustment annually in November
to the average then-current market rates for
 
                                       76
<PAGE>   82
 
the areas of operation, less $100 per day. Bayard and Chesapeake were required
to consider such adjustment each November during the term of the particular
Chesapeake drilling agreement and if no agreement could be timely reached as to
the appropriate rate adjustment, Bayard had the option to terminate the contract
for such rig at the conclusion of operations at the well then being drilled. In
December 1997, Bayard and Chesapeake were unable to agree on an appropriate rate
adjustment, so Bayard exercised its option to terminate the Chesapeake drilling
agreements.
 
COMPETITION
 
     The contract drilling industry is a highly competitive and fragmented
business characterized by high capital and maintenance costs. As a result, even
though Bayard has the fifth largest active land drilling rig fleet in the United
States, Bayard believes that such fleet represents a market share of
approximately 6% of the domestic land drilling industry. Drilling contracts are
usually awarded through a competitive bid process and, while Bayard believes
that operators consider factors such as quality of service, type and location of
equipment, or the ability to provide ancillary services, price and rig
availability are the primary factors in determining which contractor is awarded
a job. Certain of Bayard's competitors have greater financial and human
resources than Bayard, 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 Bayard in periods of high rig utilization.
 
     Competition in the market for drilling rigs caused substantial increases in
the acquisition prices paid for rigs in 1997. Continued competition and price
escalation could adversely affect Bayard's growth strategy if it is unable to
purchase additional drilling rigs or related equipment on favorable terms.
 
OPERATING HAZARDS AND INSURANCE
 
     Bayard's operations are subject to many hazards inherent in the land
drilling business, including, for example, blowouts, cratering, fires,
explosions, loss of well control, loss of hole, damaged or lost drill strings
and damage or loss from inclement weather. These hazards could cause personal
injury or death, serious damage to or destruction of property and equipment,
suspension of drilling operations, or substantial damage to the environment,
including damage to producing formations and surrounding areas. Generally,
Bayard seeks to obtain indemnification from its customers by contract for
certain of these risks. To the extent not transferred to customers by contract,
Bayard seeks protection against certain of these risks through insurance,
including property casualty insurance on its rigs and drilling equipment,
commercial general liability and commercial contract indemnity, commercial
umbrella and workers' compensation insurance.
 
     Bayard's insurance coverage for property damage to its rigs and drilling
equipment is based on Bayard's estimate of the cost of comparable used equipment
to replace the insured property. There is a deductible per occurrence on rigs
and equipment of $500,000.
 
     Bayard's third party liability insurance coverage under the general policy
is $1 million per occurrence, with a self insured retention of $100,000 per
occurrence. The commercial umbrella policy has a self insured retention of
$10,000 per occurrence with coverage of $5 million per occurrence. Bayard
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 Bayard against liability for all consequences of well
disasters, extensive fire damage or damage to the environment.
 
GOVERNMENT REGULATION AND ENVIRONMENTAL MATTERS
 
  General
 
     Bayard's operations are affected from time to time in varying degrees by
political developments and federal, state and local laws and regulations. In
particular, oil and gas production, operations and economics are or have been
affected by price controls, taxes and other laws relating to the oil and gas
industry, by changes in such laws and by changes in administrative regulations.
Although significant capital
 
                                       77
<PAGE>   83
 
expenditures may be required to comply with such laws and regulations, to date,
such compliance costs have not had a material adverse effect on the earnings or
competitive position of Bayard. In addition, Bayard's operations are vulnerable
to risks arising from the numerous laws and regulations governing the discharge
of materials into the environment or otherwise relating to environmental
protection.
 
  Environmental Regulation
 
     Bayard's activities are subject to existing federal, state and local laws
and regulations governing environmental quality, pollution control and the
preservation of natural resources. Such laws and regulations concern, among
other things, air emissions, the containment, disposal and recycling of waste
materials, and reporting of the storage, use or release of certain chemicals or
hazardous substances. Numerous federal and state environmental laws regulate
drilling activities and impose liability for discharges of waste or spills,
including those in coastal areas. Bayard has conducted drilling activities in or
near ecologically sensitive areas, such as wetlands and coastal environments,
which are subject to additional regulatory requirements. State and federal
legislation also provide special protections to animal and marine life that
could be affected by Bayard's activities. In general, under various applicable
environmental programs, Bayard may potentially be subject to regulatory
enforcement action in the form of injunctions, cease and desist orders and
administrative, civil and criminal penalties for violations of environmental
laws. Bayard may also be subject to liability for natural resource damages and
other civil claims arising out of a pollution event.
 
     Except for the handling of solid wastes directly generated from the
operation and maintenance of Bayard's drilling rigs, such as waste oils and wash
water, it is Bayard's practice to require its customers to contractually assume
responsibility for compliance with environmental regulations. Laws and
regulations protecting the environment have become more stringent in recent
years, and may, in certain circumstances, impose strict liability, rendering a
person liable for environmental damage without regard to negligence or fault on
the part of such person. Such laws and regulations may expose Bayard to
liability for the conduct of or conditions caused by others, or for acts of
Bayard which were in compliance with all applicable laws at the time such acts
were performed. The application of these requirements or adoption of new
requirements could have a material adverse effect on Bayard.
 
     Environmental regulations that affect Bayard's customers also have an
indirect impact on Bayard. Increasingly stringent environmental regulation of
the oil and gas industry has led to higher drilling costs and a more difficult
and lengthy well permitting process.
 
     The primary environmental statutory and regulatory programs that affect
Bayard's operations include the following:
 
     Oil Pollution Act and Clean Water Act. The Oil Pollution Act of 1990 amends
certain provisions of the federal Water Pollution Control Act of 1972, commonly
referred to as the Clean Water Act, and other statutes as they pertain to the
prevention of and response to spills or discharges of hazardous substances or
oil into navigable waters. Under the Oil Pollution Act, a person owning or
operating a facility or equipment, including land drilling equipment, from which
there is a discharge or threat of a discharge of oil into or upon navigable
waters and adjoining shorelines is liable, regardless of fault, as a
"responsible party" for removal costs and damages. 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.
 
     The United States Environmental Protection Agency is also authorized to
seek preliminary and permanent injunctive relief and, in certain cases, criminal
penalties and fines. State laws governing the control of water pollution also
provide varying civil and criminal penalties and liabilities in the case of
releases of petroleum or its derivatives into surface waters or into the ground.
If a discharge occurs at a well site at which Bayard is conducting drilling or
pressure pumping operations, Bayard may be exposed to claims that it is liable
under the Clean Water Act or similar state laws.
 
                                       78
<PAGE>   84
 
     Certain of Bayard's operations are also subject to EPA regulations,
including regulations that require the preparation and implementation of spill
prevention control and countermeasure plans to address the possible discharge of
oil into navigable waters. Where so required, Bayard has spill prevention
control and countermeasure plans in place.
 
     Superfund. The Comprehensive Environmental, Response, Compensation, and
Liability Act, as amended, known as CERCLA or the "Superfund" Law, imposes
liability, without regard to fault or the legality of the original conduct, on
certain classes of persons with respect to the release of a "hazardous
substance" into the environment. These persons include:
 
     - the current owner and operator of a facility from which hazardous
       substances are released;
 
     - owners and operators of a facility at the time any hazardous substances
       were disposed;
 
     - generators of hazardous substances who arranged for the disposal or
       treatment at or transportation to such facility of hazardous substances;
       and
 
     - transporters of hazardous substances to disposal or treatment facilities
       selected by them.
 
Bayard 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, Bayard
has not been named a potentially responsible party under CERCLA or any similar
state Superfund laws.
 
     Hazardous Waste Disposal. Bayard's operations involve the generation or
handling of materials that may be classified as hazardous waste and subject to
the federal Resource Conservation and Recovery Act and comparable state
statutes. The EPA and various state agencies have limited the disposal options
for certain hazardous and nonhazardous wastes and is considering the adoption of
stricter handling and disposal standards for nonhazardous wastes.
 
     As part of the Bonray Acquisition, Bayard acquired an equipment yard which
may require certain expenditures or remedial actions for the removal or cleanup
of contamination. In exchange for a $1 million cash payment to Bayard at
closing, Bayard did not require DLB Oil & Gas, Inc. to indemnify Bayard with
respect to such expenditures or remedial actions. While Bayard has not
determined whether and to what extent such expenditures or remedial actions may
be necessary or advisable, based on the presently available information, Bayard
does not believe that such expenditures will exceed $1 million. Management
believes that Bayard and its operations are in material compliance with
applicable environmental laws and regulations.
 
  Health and Safety Matters
 
     Bayard's facilities and operations are also governed by various other laws
and regulations, including the federal Occupational Safety and Health Act,
relating to worker health and workplace safety. As an example, the Occupational
Safety and Health Administration has issued the Hazard Communication Standard.
This standard applies to all private-sector employers, including the oil and gas
exploration and producing industry. The Hazard Communication Standard requires
that employers assess their chemical hazards, obtain and maintain certain
written descriptions of these hazards, develop a hazard communication program
and train employees to work safely with the chemicals on site. Failure to comply
with the requirements of the standard may result in administrative, civil and
criminal penalties. Bayard believes that appropriate precautions are taken to
protect employees and others from harmful exposure to materials handled and
managed at its facilities and that it operates in substantial compliance with
all Occupational Safety and Health Act regulations. While it is not anticipated
that Bayard will be required in the near future to make material expenditures by
reason of such health and safety laws and regulations, Bayard is unable to
predict the ultimate cost of compliance with these changing regulations.

FACILITIES AND OTHER PROPERTY
 
     Bayard leases approximately 7,500 square feet of office space for its
principal executive offices in Oklahoma City, Oklahoma at a cost of
approximately $7,000 per month and leases approximately 5,000 square feet of
office and warehouse space and ten acres of land in El Reno, Oklahoma for $2,000
per month. In addition, Bayard owns approximately ten acres of land in El Reno,
Oklahoma and five acres of land in Weatherford, Oklahoma that it uses for rig
storage and maintenance. Bayard leases a facility in Houston, Texas that
includes approximately 5,000 square feet of warehouse space and 1,300 square
feet of office space. Rental payments on the Houston facility are approximately
$1,800 per month. As part of the Bonray Acquisition, Bayard acquired
approximately 40 acres of land in Oklahoma City with facilities including 3,600
square feet of office space, an 8,000 square foot repair shop and three
warehouses. In the TransTexas Acquisition, Bayard acquired approximately 24
acres of land in Laredo, Texas with office and warehouse facilities totaling
approximately 125,000 square feet. Bayard considers all of its facilities to be
in good operating condition and adequate for their present uses.
 
EMPLOYEES
 
     As of January 19, 1999, Bayard had approximately 550 employees, of which
approximately 100 were salaried and approximately 450 were employed on an hourly
basis. None of Bayard's employees is represented by any collective bargaining
unit. Bayard management believes that Bayard's relationship with its employees
is good.
 
LEGAL PROCEEDINGS
 
     A purported class action lawsuit is pending against Bayard, certain
directors and officers of Bayard, the managing underwriters of Bayard's initial
public offering, and certain current and former stockholders of Bayard, alleging
violations of federal securities laws in connection with the initial public
offering. The lawsuit, Yuan v. Bayard Drilling Technologies, Inc., et al.
("Yuan"), was filed on February 3, 1998 in the United States District Court for
the Western District of Oklahoma. The principal plaintiff in Yuan is Tom Yuan.
The defendants in this case include Bayard, Chesapeake Energy Corporation,
Energy Spectrum LLC, James E. Brown, David E. Grose, Carl B. Anderson, III,
Merrill A. Miller, Jr., Sidney L. Tassin, Lew O. Ward, Mike Mullen, Roy T.
Oliver, Donaldson, Lufkin & Jenrette Securities Corporation, Lehman Brothers,
Inc., Prudential Securities, Inc., Rauscher Pierce Refsnes, Inc. (a predecessor
to Dain Rauscher Incorporated) and Raymond James & Associates, Inc.
 
     The plaintiffs in this lawsuit purport to sue on their own behalf and on
behalf of all persons who purchased shares of Bayard common stock on or
traceable to the initial public offering. In the lawsuit, plaintiffs allege
claims against all defendants under the Securities Act of 1933. The plaintiffs
allege that the registration statement and prospectus for Bayard's initial
public offering contained materially false and misleading information and
omitted material facts. In particular, the plaintiffs allege that such
registration statement and prospectus failed to disclose financial difficulties
of Chesapeake Energy Corporation, Bayard's largest customer, and the effects of
such difficulties on Chesapeake's ability to continue to provide Bayard with
substantial drilling contracts. The complaint further alleges that Bayard failed
to disclose pre-offering negotiations with R.T. Oliver Drilling, Inc., whom the
plaintiffs allege was a related party, for the purchase of drilling rigs. In
addition, the complaint alleges that Bayard failed to disclose that its growth
strategy required costly refurbishment of older drilling rigs that would
dramatically increase Bayard's costs, which could not be sustained by internally
generated cash flows. Plaintiffs are seeking rescission and damages.
 
     Two other suits, Khan v. Bayard Drilling Technologies, Inc., et al.
("Khan") and Burkett v. Bayard Drilling Technologies, Inc., et al. ("Burkett"),
which were filed in District Court in and for Oklahoma County, State of Oklahoma
on January 14, 1998 and February 2, 1998, respectively, and alleged essentially
the same claims as Yuan, were dismissed without prejudice in May 1998 on a joint
application filed by all parties. The plaintiffs in Khan and Burkett, along with
others, have been appointed as lead plaintiffs in the Yuan federal court suit,
now styled to include the other lead plaintiffs, as Yuan, et al., and an amended
 
                                       80
<PAGE>   86
 
consolidated complaint was filed on July 30, 1998. A motion to dismiss the
claims in this lawsuit has been filed by Bayard and the other defendants and is
currently pending before the court.
 
     Bayard is also involved in other litigation arising from time to time in
the ordinary course of its business, including workers' compensation claims and
disputes arising out of its drilling activities. Such disputes include a claim
filed against Bayard and Marathon Oil Company on November 13, 1998 in the
District Court of Washita County in the State of Oklahoma. Eldred L. and
Patricia A. Schneberger, the plaintiffs in this lawsuit, seek an order of
abatement and actual, consequential and punitive damages for losses allegedly
incurred in connection with a drilling project that utilized one of Bayard's
rigs.
 
     Bayard believes the allegations in the lawsuits referenced above are
without merit and is defending vigorously the claims brought against it. Bayard
is unable, however, to predict the outcome of these lawsuits or the costs to be
incurred in connection with their defense and there can be no assurance that
this litigation will be resolved in Bayard's favor. An adverse result or
prolonged litigation could have a material adverse effect on Bayard's financial
position or results of operations.

                        PRINCIPAL STOCKHOLDERS OF BAYARD
 
     The following table sets forth certain information regarding the beneficial
ownership of Bayard common stock as of January 15, 1999. This table discloses
the stock ownership of:
 
     - each person known by Bayard to own more than 5% of the outstanding shares
       of Bayard common stock;
 
     - each of Bayard's directors;
 
     - the Chief Executive Officer of Bayard and each of the two other persons
       who served as executive officers of Bayard during 1998; and
 
     - all executive officers and directors as a group.
 
All persons listed have an address in care of Bayard's principal executive
offices and have sole voting and investment power with respect to their shares
unless otherwise indicated.
 
     The information contained in this table with respect to beneficial
ownership reflects "beneficial ownership" as defined in Rule 13d-3 under the
Securities Exchange Act of 1934. In computing the number of shares beneficially
owned by a person and the percentage ownership of that person, shares of Bayard
common stock subject to options or warrants held by that person that are
exercisable on January 15, 1999 or become exercisable within 60 days following
January 15, 1999 are deemed outstanding. However, such shares are not deemed
outstanding for the purpose of computing the percentage ownership of any other
person. All information with respect to the beneficial ownership of any
stockholder has been furnished by such stockholder and, unless otherwise
indicated, each stockholder has sole voting and investment power with respect to
the shares listed as beneficially owned by such stockholder, subject to
community property laws where applicable. Percentage of ownership is based on
18,200,765 shares of Bayard common stock outstanding as of January 15, 1999.

                        COMPARISON OF STOCKHOLDER RIGHTS
 
GENERAL
 
     The following table summarizes the material differences between the rights
of holders of shares of Nabors common stock and the holders of shares of Bayard
common stock. Although both Nabors and Bayard are organized under the laws of
the State of Delaware, differences exist between various provisions of their
certificates of incorporation and by-laws. After the merger, Nabors' Restated
Certificate of Incorporation and Restated By-Laws will govern the rights of the
former stockholders of Bayard who receive shares of Nabors common stock.

BAYARD RIGHTS AGREEMENT
 
     On August 21, 1998, Bayard executed the Bayard rights agreement and
declared a dividend of one Right to purchase preferred stock for each
outstanding share of Bayard common stock, to stockholders of record at the close
of business on September 1, 1998. Each Right entitles the registered holder to
purchase from Bayard a unit consisting of one one-hundredth of a share of Series
A Junior Participating Preferred Stock, at a purchase price of $30 per such
fractional share, subject to adjustment.
 
     The Rights will separate from Bayard common stock and a "distribution date"
will occur, with certain exceptions, upon the earlier of:
 
     - ten days following a public announcement that a person or group of
       affiliated or associated persons (an "acquiring person") has acquired, or
       obtained the right to acquire, beneficial ownership of 15% or more of the
       outstanding shares of Bayard common stock; or
 
     - ten business days following the commencement of a tender offer or
       exchange offer that would result in a person's becoming an acquiring
       person.
 
The Rights are not exercisable until the distribution date and will expire at
the close of business on August 21, 2008, unless earlier redeemed or exchanged
by Bayard.
 
     If a person becomes an acquiring person (a "Flip-In Event"), each holder of
a Right, other than an acquiring person, will have the right to receive, upon
exercise of such Right, a number of shares of Bayard common stock having a
current market price equal to two times the exercise price of the Right. If
Bayard is acquired in a merger or other business combination transaction, or 50%
or more of Bayard's assets or earning power is sold or transferred (a "Flip-Over
Event"), each holder of a Right, other than an acquiring person, shall have the
right to receive, upon exercise, a number of shares of common stock of
 
                                       86
<PAGE>   92
 
the acquiring company having a current market price equal to two times the
exercise price of the Right. Nevertheless, these rights will not accrue if the
Bayard Board approves the triggering transaction.
 
     At any time until ten days following the first date of public announcement
of the occurrence of a Flip-In Event, Bayard may redeem the Rights in whole, but
not in part, at a price of $0.01 per Right, payable, at Bayard's option, in
cash, shares of Bayard common stock or other consideration. Under certain
circumstances set forth in the Bayard rights agreement, redemption may only be
made if a majority of the Bayard Board is composed of directors that are
independent of any acquiring person. Immediately upon the effectiveness of the
action of the Bayard Board ordering redemption of the Rights, the Rights will
terminate and the only right of the holders of Rights will be to receive the
$0.01 redemption price.
 
     At any time after the occurrence of a Flip-In Event, and before a person's
becoming the beneficial owner of 50% or more of the shares of Bayard common
stock then outstanding or the occurrence of a Flip-Over Event, Bayard, if a
majority of the Bayard Board is composed of directors independent of any
acquiring person, may exchange the Rights, other than Rights of an acquiring
person, in whole or in part, at an exchange ratio of one share of Bayard common
stock per Right, subject to adjustment.
 
     On October 19, 1998, Bayard entered into an amendment to the Bayard rights
agreement. Under the terms of the amendment, Nabors, or any of its affiliates,
shall not become an acquiring person unless it becomes the beneficial owner of
at least 20% of the outstanding shares of Bayard common stock. In addition, no
person shall become the beneficial owner of shares of Bayard common stock held
by others as a result of the execution of the stockholder agreements. The Bayard
rights agreement was also amended to provide that it shall not apply to or be
affected by the execution or performance of the merger agreement, the stock
option agreement, the stockholder agreements, or any other transaction
contemplated by those agreements. See "The Merger Agreement and Related
Agreements -- Amendment of Bayard Rights Agreement."

                      NABORS' YEAR 2000 COMPLIANCE PROGRAM
 
     Background. The Y2K problem refers to the fact that a number of computers,
computer programs and other equipment with embedded chips or processors,
referred to collectively as "systems," in use today use two digits rather than
four digits to define the applicable year. Any systems that are date sensitive
may recognize a date of "00" as the year 1900 rather than the year 2000. This
could result in miscalculations or system failures causing disruptions of
operations, as well as potentially exposing Nabors to third party liability.
 
     Y2K Compliance Program. Nabors has initiated a Y2K compliance program to
ensure that all of the critical systems and processes that are under its direct
control remain functional. Nabors has organized a task force of key employees
and engaged an outside consultant to assist in the management of its Y2K
compliance program. Nabors' Y2K compliance program will focus on Nabors' systems
as well as the systems of key third party service providers, product suppliers
and customers. The first phase of the program consists of inventorying or
identifying all systems. The identified systems will then be prioritized and all
critical systems will be assessed for Y2K compliance. Systems will be remediated
or replaced as necessary and contingency plans will be developed if deemed
appropriate. Nabors is currently in the inventory and assessment phases of the
program, which it expects to complete by March 31, 1999, with the entire program
being completed well in advance of the Year 2000.
 
     Critical Systems. The systems that are critical to Nabors' operations
include both its accounting and administrative systems and its operational
systems. Upgrades to a number of Nabors' accounting and administrative systems
in the ordinary course of business have had the added benefit of resolving
certain Y2K compliance issues. Accordingly, Nabors believes its critical
accounting and administrative systems, which consists primarily of computer
hardware and software, to be substantially Y2K compliant. Nabors' critical
operational systems consist primarily of systems in use on Nabors' drilling
rigs. Nabors is currently performing an inventory of each drilling rig's
critical systems and is in the process of assessing these systems for Y2K
compliance. Currently, Nabors is not in a position to reasonably predict the
likely worst case Y2K scenario for its drilling rigs, but expects to be able to
do so following the completion of its drilling rig assessment.
 
     Key Third Parties. Third parties that are key to Nabors' operations include
suppliers that provide capital equipment and other supplies and services
essential to the operation of Nabors' drilling rigs or business, and customers
that provide a source of revenue and cash flow to Nabors. Any significant Y2K
disruptions of Nabors' key suppliers and customers could adversely impact
Nabors' financial condition, results of operations or cash flows. Nabors is
directly contacting key suppliers and customers to determine the state of their
Y2K readiness, and is reviewing posted information of various suppliers in
assessing its own Y2K compliance. Because Nabors must rely on representations
made by key third parties with respect to their state of Y2K readiness, it
cannot guarantee that all of the Systems of key third parties that are relied
upon by Nabors will remain functional. Nabors expects to have completed
identifying and contacting all key third parties with respect to their Y2K
readiness by March 31, 1999.
 
     Costs. To date, the incremental costs incurred by Nabors that relate solely
to the Y2K compliance program have been minimal. These costs are exclusive of
upgrades made to Nabors' systems in the ordinary course of business and consist
primarily of fees paid to an outside consultant and internal employee time.
Based upon Nabors' current assessments, the costs to complete Nabors' Y2K
compliance program will not have a material effect on Nabors' financial
condition, results of operations or cash flows. All current and future costs
related to Nabors' Y2K compliance program have been and are expected to be
funded with cash generated from Nabors' operations.
 
     Risks. There are numerous uncertainties that make the ultimate impact of
Y2K disruptions in the United States or other countries where Nabors operates
difficult to predict. While Nabors will obtain representations from key third
parties with respect to their Y2K readiness, there will be certain Systems or
processes relied on by Nabors that are outside of Nabors' control. The failure
by key third parties to correct their Y2K issues could adversely effect Nabors.
Additionally, Nabors could be unsuccessful in identifying and remediating or
replacing all of its non-compliant systems, and as such, Nabors' financial
                                       88
<PAGE>   94
 
condition, results of operations and cash flows could be materially impacted.
While Nabors does not currently anticipate any catastrophic system failures, no
assurances can be made that such failures will not ultimately occur.
 
     Contingency Plans. If during the course of Nabors' assessment of its
critical systems, it is determined that the risk of Y2K disruptions is
significant, contingency plans will be developed as appropriate. Such plans
might include the use of alternative service providers or product suppliers.
Currently, Nabors does not have any contingency plans in place based on current
Y2K readiness assessments.

                             STOCKHOLDER PROPOSALS
 
     The 1999 Annual Meeting of Stockholders of Bayard will be held only if the
merger is not consummated. In order to be considered for inclusion in the proxy
statement for the 1999 Annual Meeting of Stockholders of Bayard, stockholder
proposals intended to be presented at such meeting and included in such proxy
statement under Rule 14a-8 of the Securities Exchange Act of 1934 must have been
received by Bayard at its principal executive offices, Attention: Secretary, on
or before December 11, 1998. Notice of a stockholder proposal intended to be
presented at such meeting but not included in such proxy statement under Rule
14a-8 under the Securities Exchange Act of 1934 must be received by Bayard at
its principal executive offices, Attention: Secretary, no later than 60 days
before the 1999 Annual Meeting or, if later, ten days after the first public
notice of the 1999 Annual Meeting is sent to the stockholders of Bayard in order
to be considered "timely" under Rule 14a-4(c) of the Commission. Under the rules
of the Commission, if a stockholder fails to notify Bayard of its intention to
bring a non-Rule 14a-8 proposal before the 1999 Annual Meeting on or before such
date, then the proxy card solicited by the Bayard Board may grant discretionary
voting authority to the proxies named in the Bayard Board's proxy card with
respect to the non-Rule 14a-8 proposal.

$1,180.
 
     During 1996 the Company acquired property and equipment totaling $9,841
through the issuance of stock and options and assumed a net deferred income tax
liability of $331. The Company acquired property and equipment through trade
payables and payables to affiliates totaling $1,390. The Company transferred
property and equipment totaling $29, net of accumulated depreciation of $1,254
to an affiliate which has been reflected as a decrease in payables to
affiliates. The Company issued stock options and warrants in exchange for

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
   INFORMATION FOR THE PERIODS ENDED SEPTEMBER 30, 1998 AND 1997 IS UNAUDITED
 
NOTE A -- NATURE OF OPERATIONS
 
     Bayard Drilling Technologies, Inc. together with its predecessor, (the
"Company"), a Delaware corporation, is the successor to the drilling operations
of Anadarko Drilling Company ("Anadarko"), which began drilling operations in
1980. The Company provides land-based contract drilling services to major and
independent oil and gas companies in the Mid-Continent and Gulf Coast regions of
the United States.
 
     Beginning in October 1996, AnSon Partners Limited Partnership ("APLP")
initiated a series of transactions among its wholly owned affiliates, Anadarko,
a partnership, and Bayard Drilling Company ("BDC"), a corporation, and the
Company. These series of transactions resulted in the corporate capitalization
of the Company in December 1996 with net assets, primarily drilling rigs,
previously owned by Anadarko. Such transactions were accounted for as a
reorganization of entities under common control.
 
NOTE B -- SUMMARY OF ACCOUNTING POLICIES
 
     The summary of significant accounting policies applied in the preparation
of the accompanying financial statements follows.
 
1. BASIS OF PRESENTATION AND CONSOLIDATION
 
     The financial statements and information for periods prior to December 1,
1996 represent those of the predecessor. The consolidated financial statements
for periods after December 31, 1996 include the accounts of the Company and its
wholly owned subsidiaries, Trend Drilling Company ("Trend") and WD Equipment,
L.L.C. and Bonray Drilling Corporation. All significant intercompany accounts
and transactions have been eliminated.
 
2. CASH
 
     The Company considers all cash and investments with an original maturity of
90 days or less to be cash equivalents. The Company maintains its cash in a bank
deposit account which, at times, may exceed federally insured limits. The
Company has not experienced any losses in such accounts. At December 31, 1997
and September 30, 1998, the Company had cash and cash equivalents in or at four
and three financial institutions respectively, where the balance exceeded
federally insured limits, in total by approximately $48.9 and $19.4 million,
respectively.
 
3. RESTRICTED INVESTMENTS
 
     Restricted investments consist of certificates of deposits pledged to state
insurance departments and insurance companies to support payment of workers
compensation claims.
 
4. CONCENTRATION OF CREDIT RISK
 
     The primary market for the Company's services are independent oil and gas
companies whose level of activities are related to, among other things, oil and
gas prices. The Company performs ongoing credit evaluations of its customers and
provides for potential credit losses when necessary. No allowance was required
at December 31, 1997, 1996 or 1995. At December 31, 1997 and September 30, 1998,
approximately 53% and 48%, respectively, of the Company's trade receivables and
over 63% and 48%, respectively, of total revenues were derived from the
Company's five largest customers in terms of total revenues.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
5. PROPERTY AND EQUIPMENT
 
     Property and equipment are stated at cost, reduced by provisions to
recognize economic impairment in value when management determines that such
impairment has occurred. Drilling equipment is depreciated using the declining
balance method (which approximates straight line) over the estimated useful
lives from five to fifteen years. Other property and equipment are depreciated
on the same basis over estimated useful lives from three to ten years.
Refurbishments and upgrades of drilling equipment are capitalized if such
expenditures are significant and extend the lives of the equipment. Maintenance
and repairs are expensed as incurred. When assets are sold, retired or disposed
of, the cost and related accumulated depreciation are eliminated from the
accounts and the gain or loss is recognized.
 
     It is the Company's policy to capitalize interest on construction costs for
rig refurbishments during the period in which those costs are incurred. The
Company incurred interest costs of approximately $3.6 million during 1997 and $5
million for the nine months ended September 30, 1998 of which approximately
$565,000 and $1.6 million, respectively, was capitalized in property and
equipment for rig construction. No interest costs were capitalized in 1996 or
1995.
 
6. REVENUE RECOGNITION
 
     Revenues generated from the Company's dayrate drilling contracts are
recognized as services are performed and revenues generated from the Company's
footage drilling contracts are recognized as a percentage of completion. For all
drilling contracts under which the Company bears the risk of completion (such as
turnkey contracts) revenues and expenses are recognized using the completed
contracts method. When estimates of projected revenues and expenses indicate a
loss, the total estimated loss is accrued.
 
7. NET EARNINGS (LOSS) PER SHARE
 
     Earnings per share are computed based on the weighted average number of
basic and diluted shares outstanding during the period pursuant to SFAS No. 128.
SFAS No. 128 simplifies the standards for computing earnings per share by
replacing the presentation of primary earnings per share with a presentation of
basic earnings per share and by simplifying the calculation of diluted earnings
per share. A reconciliation of the numerator and denominator used in the
calculation of earnings per share is as follows:

</TABLE>
 
     Pro forma net earnings (loss) per share are presented to reflect the
provision for income taxes for periods Anadarko was a partnership.
 
     Options to purchase 397,000 shares of common stock at $23 per share were
granted in November 1997 but were not included in the computation of diluted
earnings per share because the options' exercise price was greater than the
average market price of the common shares. The options, which expire on November
4, 2003, were still outstanding at December 31, 1997.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
8. INCOME TAXES
 
     Historical income taxes were not provided in the financial statements for
earnings attributable to Anadarko since the partners would pay income taxes or
receive as a deduction their distributive share of Anadarko's taxable income or
loss. The proforma income tax expense for 1996 was calculated using an effective
tax rate of 38%.
 
     The Company uses the liability method of accounting for deferred income
taxes under SFAS No. 109, whereby deferred tax assets and liabilities are
recognized based upon differences between the financial statement and tax bases
of assets and liabilities using presently enacted tax rates. If it is more
likely than not that some portion or all of a deferred tax asset will not be
realized, a valuation allowance is recognized.
 
9. GOODWILL AND OTHER ASSETS
 
     Goodwill related to the acquisition of Trend and Bonray is being amortized
over fifteen years. Amortization expense of goodwill of $375,062 and $653,976,
respectively, has been recognized as of December 31, 1997 and September 30,
1998.
 
     Other assets consist of (i) organizational costs incurred for the
organization of Bayard, (ii) debt issuance costs incurred on the term loan, and
(iii) issuance costs of the Senior Notes. Amortization expense for organization
costs is recognized over five years and debt issuance costs over the life of the
loan, which approximates five years, both on a straight-line basis. Amortization
expense of $1.4 million, $63,000 and $578,620 has been recognized for the years
ended December 31, 1997 and 1996 and for the nine months ended September 30,
1998, respectively.
 
     On an ongoing basis, management reviews the valuation and amortization of
goodwill and other intangibles to determine possible impairment. The
recoverability of these assets is assessed by determining whether the carrying
value can be recovered from undiscounted future cash flows.
 
10. USE OF ESTIMATES
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect certain reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period; accordingly actual results could differ from those estimates.
The Company has significant estimates for workers compensation liability due to
the retention of $500,000 per occurrence. At December 31, 1997 and 1996 and for
the nine months ended September 30, 1998, estimates for this retention were $1.7
million, $20,000 and $1.6 million, respectively.
 
11. FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The Company's financial instruments consist of cash and investments which
approximate fair value because of the short maturity of those instruments, a
payable to an affiliate which approximates fair value due to the demand nature
of this obligation, a floating rate term loan which approximates fair value
because the interest rate adjusts to the market rate, and notes payable which
approximate fair value because the interest rates on these notes reflects the
borrowing terms currently available to the Company.
 
12. INTERIM FINANCIAL STATEMENTS AND DISCLOSURES
 
     In the opinion of management of Bayard Drilling Technologies, Inc.
("Bayard" or the "Company"), the unaudited interim financial statements for the
nine months ended September 30, 1998 and 1997

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
include all adjustments, consisting of normal recurring accruals, necessary to
present fairly the Company's financial position as of September 30, 1998 and
results of operations and cash flows for the nine months ended September 30,
1998 and 1997. Results for the period ended September 30, 1998 are not
necessarily indicative of the results to be expected for the entire fiscal year.
For further information, refer to the financial statements and footnotes thereto
included in the Company's Annual Report on Form 10-K for the year ended December
31, 1997.
 
13. STOCK BASED COMPENSATION
 
     The Company applies APB Opinion 25 in accounting for its stock option
plans. Under this standard, compensation expense is only recognized for grants
of options which include an exercise price less than the market price of the
stock on the date of grant. Accordingly, based on the Company's grants for 1996,
for the year ended December 31, 1997 and for the nine months ended September 30,
1998, the Company recognized $0 and approximately $310,000 and $0, respectively,
of deferred compensation and $0 and approximately $52,000 and $39,000,
respectively, of compensation expense. For grants of options which include an
exercise price equal to or greater than the market price of the stock on the
date of grant, the Company has disclosed the pro forma effects of recording
compensation based on fair value in Note N to the financial statements as
allowed by Financial Accounting Standard No. 123 "Accounting for Stock-Based
Compensation."
 
NOTE C -- ACQUISITIONS
 
     On May 1, 1997, the Company completed the acquisition of the common stock
of Trend ("Trend Acquisition") for $18 million in cash and 250,000 shares of
common stock which equates to $10.64 per share based on the appraisals of the
fair market value of the property and equipment acquired of $21,532,000. The
Company incurred costs of approximately $307,000 in connection with this
acquisition.
 
     The Trend Acquisition was accounted for as a purchase. The following is an
analysis of the allocation of the purchase price:

     On May 30, 1997, the Company acquired WD Equipment, L.L.C. (which owned six
drilling rigs, but had no operations) from Ward Drilling Company, Inc. ("Ward
Acquisition") for approximately $8 million in cash and 400,000 shares of common
stock which equates to $8.95 per share based on the appraisal of the fair market
value of the assets acquired of $11,931,000. The Company also issued warrants to
purchase 200,000 shares of common stock at $10.00 per share. The warrant had an
estimated fair market value of $294,000 at the agreement closing date and was
recorded as an increase in property and equipment and additional paid in
capital.
 
     On October 16, 1997, the Company completed the acquisition of Bonray
("Bonray Acquisition"), subject to certain working capital adjustments, for
3,015,000 shares of Common Stock, which equates to $11.86 per share based on the
appraisals of the fair market value of the property and equipment acquired of
$34,976,000.

     On June 26, 1998, the Company completed the acquisition of 25 drilling rigs
and certain related equipment and other assets from TransTexas Gas Corporation
("TransTexas") for $75 million in cash (the "TransTexas Acquisition"), which was
allocated to the cost basis of the rigs and equipment. The rigs will be
depreciated pursuant to the Company's depreciation policy. TransTexas utilized
the rigs solely for their own drilling activities and did not contract the rigs
to third parties. Therefore, there were no third party drilling revenues.
TransTexas accounted for the rigs and related costs and expenses as a cost
center. All of the acquired rigs are mechanical rigs capable of drilling to
depths of 12,000 feet or greater, with twelve of the rigs capable of drilling to
depths of 20,000 feet or greater. Four of the drilling rigs are awaiting
refurbishment when market conditions warrant. In addition, the Company and
TransTexas have entered into an Alliance Agreement that provides that for a
period of 30 months, if TransTexas engages in any land drilling activities in
Alabama, Louisiana, Mississippi, Oklahoma, New Mexico or Texas, TransTexas will
engage the Company to provide up to 15 of the Company's rigs for wells on which
TransTexas serves as operator.

NOTE E -- CHANGE IN ESTIMATED LIVES
 
     Effective January 1, 1995, the Company changed the estimated remaining
lives of its drilling rigs and other related drilling equipment to 84 months
from remaining lives which ranged from 31 months to 113 months. The Company also
changed the estimated remaining life of drill collars from 20 months to 36
months. These changes were made to more closely approximate the remaining useful
lives of such assets. The effect of this change was to decrease the historical
net loss by approximately $539,000 and to reduce the pro forma net loss by
approximately $539,000 or $.05 per share (Note B(7)) for the year ended December
31, 1995.
 
     Effective January 1, 1996, the Company changed the estimated remaining
lives of certain drilling component equipment from 84 months to 120 months and
changed the estimated remaining life of drill collars and pipe from 36 months to
60 months. After review and study by the Company, the useful lives of drilling
rigs acquired after January 1, 1996 were changed from 84 months to 144 months.
These changes were made to more closely approximate the remaining useful lives
of such assets. The effect of these changes was to increase the historical net
earnings by approximately $405,000 and to increase pro forma net earnings by
approximately $251,000, net of pro forma income taxes of $154,000, or $.02 per
share for the year ended December 31, 1996.
 
     Effective July 1, 1997, the Company changed the estimated remaining lives
of its drilling rigs and other related drilling equipment to 180 months from
remaining lives of 144 months. These changes were made to more closely
approximate the remaining useful lives of such assets. The effect of these
changes was to increase earnings for the year ended December 31, 1997 by
approximately $505,000, net of income taxes of $310,000, or $.04 per share, on a
diluted basis.
 
NOTE F -- INCOME TAXES
 
     On October 28, 1996, Anadarko conveyed its operating assets to its
wholly-owned subsidiary, BDC, which caused a change in tax status of the
drilling operations from a partnership to a taxable corporation. A deferred tax
asset was recognized for the temporary differences which existed at the date of
conveyance together with a related valuation allowance. At December 31, 1997,
the Company has net operating loss carry forwards of approximately $2 million,
of which $418,000 and $1,582,000 will expire in 2011 and 2012, respectively, if
unused.

     The Company's valuation allowance on tax assets was established October 28,
1996 due to a change in taxable status and decreased $1,818,000 during the
period from October 28, 1996 to December 31, 1996. The Company was not a taxable
entity in 1995. Effective December 1, 1996, the Company acquired assets with
deferred tax liabilities of approximately $2 million in which the purchase price
allocation resulted in the reduction of the Company's tax asset valuation
allowance of approximately $1,724,000. In 1997 the Company acquired assets with
deferred tax liabilities of approximately $13,080,000, which eliminated the
Company's tax asset valuation.
 
NOTE G -- LONG-TERM DEBT AND SUBORDINATED NOTES
 
     Long-term debt at December 31, 1996 consisted of borrowings under loan
agreements (the "Loan Agreements") which provide for a term loan (the "Term
Loan") and a revolving loan (the "Revolving Loan"). The Term Loan of $7,000,000
bore interest at the Company's choice of LIBOR plus 4.25% (9.65% at December 31,
1996) or the prime rate of Chase Manhattan Bank, N.A. and requires monthly
payments of principal and interest in amounts sufficient to repay borrowings at
maturity on March 31, 2002. The Loan Agreements permit borrowings to a maximum
of $20 million under the Term Loan if defined collateral provisions are met. The
loan was collateralized by drilling equipment. The Loan Agreements also permit
borrowings up to $4 million under the Revolving Loan through December 31, 1998
subject to a $2 million limitation if the borrowings under the Term Loan exceed
$17 million.

                       BAYARD DRILLING TECHNOLOGIES, INC.
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     Starting in 1997, the Loan Agreements require the maintenance of defined
collateral values, cash flow and liquidity ratios, financial reporting
requirements, and the maintenance of total liabilities to tangible net worth not
greater than 1.25 and imposes certain limitations on capital expenditures and
incurrence of additional debt.
 
     In May 1997, the Company amended and increased the availability under the
Loan Agreements. The Term Loan provides the Company up to $30.5 million for the
purchase of additional land drilling rigs, the refurbishment of such rigs and
equipment and for working capital purposes. The Revolving Loan provides the
revolving credit loans of up to $10 million ($2 million of which is available
for the issuance of letters of credit) for general corporate purposes. Amounts
outstanding under the Revolving Loan (none at December 31, 1997) bear interest
based on Fleet National Bank's prime rate plus 1.5% (approximately 10% at
December 31) and mature in April 2000. Amounts outstanding under the Term Loan
of approximately $27.1 million at December 31, 1997, bear interest, at the
election of the Company, at floating rates equal to Chase Manhattan Bank's prime
rate plus 2.0% or LIBOR plus 4.25% (approximately 10% at December 31) and mature
in March 2002. The Loan Agreements are collateralized by substantially all of
the assets of the Company, including drilling rigs, equipment and drilling
contracts, and contain customary restrictive covenants (including covenants
restricting the ability of the Company to pay dividends or encumber assets) and
an affirmative covenant to maintain Total Available Liquidity (as defined in the
Loan Agreements) of at least $4.5 million through December 31, 1997 and $3
million through December 31, 1998. Pursuant to the Loan Agreements, the Company
must maintain certain financial ratios, including a Cash Flow Coverage ratio (as
defined in the Loan Agreements) of at least 1.25 to 1 until December 1997, 1.5
to 1 in 1998 and 1.75 to 1 thereafter, and a ratio of Total Liabilities (as
defined in the Loan Agreements) to Tangible Net Worth no greater than 1.25 to 1
in 1997 and 1 to 1 in 1998. Under the Loan Agreements the Company is obligated
to pay certain fees, including an annual commitment fee in an amount equal to
0.5% of the unused portion of the commitment.
 
     Additionally, the Company issued Subordinated Notes due May 1, 2003 in the
original principal amounts of $18 million and $2.52 million (the "Subordinated
Notes") to Chesapeake Energy Corporation ("Chesapeake") and Energy Spectrum
Partners LP ("Energy Spectrum"), respectively. The Subordinated Notes bear
interest at either (i) 11% per annum, payable in cash or (ii) 12.875% per annum,
payable in the form of additional Subordinated Notes, which interest is payable
quarterly in arrears. On each quarterly interest payment date, the Company may
make an election as to the interest rate to be applied for the previous quarter.
The Subordinated Notes are redeemable, solely at the option of the Company, in
whole or in part, at any time after May 31, 1998 at varying redemption prices.
The Company must offer to redeem the Subordinated Notes upon the occurrence of
certain events constituting a "Change of Control" (as defined in the
Subordinated Notes) at a redemption price equal to 100% of the principal amount
thereof, together with accrued and unpaid interest, if any, to the date of
redemption. The Subordinated Notes are convertible into Common Stock at the
option of the Company, in whole or in part, in conjunction with a "Convertible
Event" (as defined in the Subordinated Notes), which includes certain
underwritten public offerings (including the Initial Public Offering), mergers,
consolidations and other business combination transactions. The Subordinated
Notes are general unsecured subordinated obligations of the Company that are
subordinated in rights of payment to all existing and future senior indebtedness
of the Company, pari passu with all existing and future subordinated
indebtedness of the Company and senior in right of payment to all future junior
subordinated indebtedness of the Company. At December 31, 1997, the amount of
Subordinated Notes outstanding was approximately $2.5 million as the $18 million
Subordinated Note to Chesapeake was extinguished in November 1997 with proceeds
from the Initial Public Offering. See Note "J" for further discussion on the
discount that was recorded related to this subordinate debt.
 
     The Company also has three notes totaling approximately $3.4 million at
December 31, 1997 and $2.5 million at September 30, 1998, with a capital
financing corporation. The debt bears interest at 9.5%

and is collateralized by certain equipment (top drives) of the Company and
letters of credit totaling approximately $700,000. The debt matures in July,
October and November of 2000. The note agreement does not specify any
restrictive financial covenants that must be met but contains a cross default
provision that states any default on the Company's Term or Revolving Notes
constitutes a default on this note as well.
 
     The Company recorded an extraordinary loss of $4.0 million (net of income
tax effect of $1.3 million) in the fourth quarter relating to the early
extinguishment of certain subordinate debt in the amount of approximately $2.1
million and other payments in the amount of approximately $3.2 million by
utilizing proceeds from the Company's Initial Public Offering completed in
November 1997.

obligations are as follows:

     On June 26, 1998, the Company issued $100 million of Senior Notes and used
$75 million of such proceeds to fund the TransTexas Acquisition. The Company
used the remaining proceeds for general corporate purposes, including
acquisitions of drilling equipment and the refurbishment of rigs. The Senior
Notes mature on June 30, 2005. Interest on the Senior Notes is payable
semi-annually on June 30 and December 31 of each year, commencing on December
31, 1998. The Senior Notes are not redeemable prior to June 30, 2003, on or
after which the Senior Notes will be redeemable, in whole or in part, at the
option of the Company, at the redemption prices set forth in the Indenture
relating to the Senior Notes (the "Indenture"), plus accrued and unpaid interest
and certain other charges, if any, thereon to the date of redemption. In
addition, at any time on or before June 30, 2001, the Company may redeem up to
35% of the original aggregate principal amount of the Senior Notes with the net
proceeds of certain qualifying equity offerings at a redemption price equal to
111% of the principal amount thereof, plus accrued and unpaid interest and
certain other charges, if any, thereon to the date of redemption, provided that
at least $65 million in aggregate principal amount of Senior Notes remains
outstanding immediately after the occurrence of such redemption. Upon a
transaction resulting in a change of control, each holder of the Senior Notes
will have the right to require the Company to repurchase all or any part of such
holder's Senior Notes at a price equal to 101% of the principal amount thereof,
plus accrued and unpaid interest and certain other charges, if any, thereon to
the date of repurchase. The Senior Notes are senior unsecured obligations of the
Company and rank pari passu in right of payment with all existing and future
senior indebtedness and other senior obligations of the Company, and senior in
right of payment to all future subordinated indebtedness of the Company.
 
     Each of the Company's wholly owned domestic subsidiaries (each, a
"Guarantor") has issued a guarantee (a "Guarantee") of the Company's obligations
under the Notes. The Guarantees are senior unsecured obligations of each
respective Guarantor and rank pari passu in right of payment with all other
indebtedness and liabilities of such Guarantor that are not subordinated by
their terms to other indebtedness of such Guarantor, and senior in right of
payment to all subordinated indebtedness of such Guarantor.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     The Company had outstanding at September 30, 1998 $16.7 million of long
term debt under the Term Loan Agreement. The Term Loan was incurred to finance
the purchase of certain land drilling rigs, the refurbishment of such rigs and
equipment and for working capital purposes. On May 14, 1998, in connection with
the Company's corporate reorganization into a holding company structure, (i) the
Company prepaid $6.2 million of the Term Loan, obtained a release of all
collateral for the Term Loan, except 12 drilling rigs and related equipment, and
transferred to Bayard Drilling, L.P., the Company's wholly owned operating
subsidiary ("Bayard Drilling"), substantially all of its assets, subject to such
liens, and (ii) Bayard Drilling and Bayard Drilling, L.L.C., another wholly
owned subsidiary of the Company ("Bayard L.L.C."), agreed to guarantee the Term
Loan. Prior to such prepayment and collateral release, the Term Loan was secured
by substantially all of the assets of Bayard and Trend. In connection with the
Senior Notes Offering, the Term Loan was further amended to add Bonray as a
guarantor of the Company's obligations.
 
     The Term Loan Agreement requires the Company and its subsidiaries to
maintain collateral security for the Term Loan based on appraised fair market
value and orderly liquidation value of the Company's drilling rigs and
associated rig equipment equivalent to the balance of the Term Loan, and adhere
to specified cash flow, leverage and liquidity ratios and minimum net worth and
liquidity requirements. The Term Loan Agreement contains restrictions on, among
other things, the ability of the Company and its subsidiaries to pay dividends,
make investments, incur indebtedness and liens, and make capital expenditures
and requires the maintenance of liquidity of $3 million through December 31,
1998. The Term Loan Agreement also contains affirmative covenants typical of
secured loan arrangements with finance companies, such as requiring financial
reports, insurance maintenance, legal, environmental and permit compliance. The
Company is prohibited from prepaying the Term Loan until after December 31,
1999.
 
     The Term Loan bears interest at the Company's choice of LIBOR plus 4.25%
per annum (9.89% at September 30, 1998) or the prime rate of The Chase Manhattan
Bank plus 2.00% per annum and requires equal monthly payments of principal,
together with accrued interest, in amounts sufficient to repay borrowings at
maturity on March 31, 2002.
 
     The Revolving Loan Agreement provides revolving credit loans, subject to a
borrowing base comprised of a portion of the Company's accounts receivable, of
up to $10 million ($2 million of which is available for letters of credit) for
general corporate purposes. The Company has not borrowed under the Revolving
Loan Agreement since November 1997 but has approximately $1.3 million of letters
of credit outstanding thereunder.
 
     Any borrowings under the Revolving Loan Agreement would bear interest based
on Fleet National Bank's prime rate plus 1.5% (approximately 10.0% at September
30, 1998). A portion of the proceeds from the Initial Public Offering was used
to repay all outstanding amounts under the Revolving Loan Agreement. The Company
pays certain fees under the Revolving Loan Agreement, including a commitment fee
equal to 0.5% of the unused portion of the maximum commitment. Fleet's
commitment to lend under the Revolving Loan Agreement ends in April 2000. The
Company may terminate the Revolving Loan Agreement upon 60 days' prior written
notice to Fleet and the payment of a termination fee of 2% of the facility.
 
     The Revolving Loan Agreement is collateralized by certain assets of Bayard
and Trend that were transferred to Bayard Drilling pursuant to the Company's
corporate reorganization into a holding company structure, including accounts
receivable, certain equipment and inventory, the Company's El Reno, Oklahoma
yard and the same 12 drilling rigs that collateralize the Term Loan Agreement,
together with equipment and drilling contracts related to such rigs. The
Revolving Loan Agreement is also secured by the receivables and certain other
assets of Bayard, Bayard Drilling, Bayard LLC, Trend and Bonray. Until May 14,
1998, the Revolving Loan Agreement was also collateralized by all drilling rigs
of Bayard and

Trend, upon which date Fleet released all but such 12 rigs and related assets.
Bayard Drilling, Bayard LLC, Trend and Bonray have agreed to guarantee the
obligations under the Revolving Loan Agreement. The Revolving Loan Agreement
contains customary restrictive covenants that are substantially similar to the
covenants contained in the Term Loan Agreement.
 
NOTE H -- RELATED PARTY TRANSACTIONS
 
     Before the corporate capitalization, AnSon Gas Corporation a wholly owned
affiliate of APLP served as the managing general partner responsible for all
management and operational functions of the Company and charged the Company for
such expenses. The Company expensed approximately $198,000 and $390,000 for such
services received in 1996 and 1995, respectively.
 
     Prior to December 31, 1996, the Company and its affiliates made advances to
each other from time to time which generally had no specific repayment terms.
 
     In December 1996, Anadarko granted the Company a transferable option,
exercisable at any time prior to June 30, 1998, to either purchase from Anadarko
a storage yard located in Weatherford, Oklahoma (the "Weatherford Storage Yard")
for a price of $1,000 in cash or lease from Anadarko, for any period specified
by the Company through a date not later than December 31, 1999, the Weatherford
Storage Yard for a lease price of $100 per year. In August 1997, the Company
acquired from Anadarko approximately 5 acres of land also in Weatherford,
Oklahoma, in consideration for the relinquishment by the Company of the option
to acquire or lease the Weatherford Storage Yard.
 
     In May 1997, the Company paid Energy Spectrum a fee in the amount of
$220,000 for financial advisory and other services rendered to the Company in
connection with the completion of the Trend Acquisition, including the
evaluation and negotiation of the Trend Acquisition and for assistance in the
arrangement of alternative financial sources and structuring, negotiating and
closing the amended financing arrangements with CIT and Fleet. The Company also
reimbursed Energy Spectrum for expenses incurred in connection with the
rendering of such services.
 
     The Company purchased drilling equipment and supplies from an affiliate
totaling $2,862,000 and $779,000 in 1996 and 1995, respectively. The Company
also transferred drilling equipment to an affiliate at the Company's basis
totaling $29,000, net of accumulated depreciation, which resulted in a decrease
in payable to affiliate. The Company has in the past purchased rigs and related
equipment from U.S. Rig & Equipment, Inc., an affiliate of Roy T. Oliver, who
served as a director of the Company until his resignation on August 13, 1997.
During 1997, the Company purchased approximately $5.0 million from U.S. Rig &
Equipment, Inc. Additionally, in August 1997, the Company sold one of its rigs
to an affiliate of Mr. Oliver for $500,000. Additionally, in November 1997, the
Company agreed to acquire six rigs and related drilling equipment for $14
million and such rigs will require additional refurbishment prior to placement
into service. In connection therewith, the Company made a cash down payment of
$3.5 million and closed the transaction in January 1998.
 
     The Company has engaged affiliates of APLP and other related affiliates for
trucking services related to the movement of the Company's rigs on numerous
occasions. During 1997 and the nine months ended September 30, 1998, the Company
utilized these affiliates in consideration for such trucking services of
approximately $2.7 million.
 
     From December 13, 1996 through December 31, 1997, APLP made available to
the Company certain of APLP's employees, office space and administrative
equipment, such as computer and telephone systems. In consideration for such
assistance, the Company has reimbursed APLP an aggregate of approximately
$236,000.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     Interest expense incurred during the year ended December 31, 1997 and for
the nine months ended September 30, 1998 included approximately $680,000 and
$71,000, respectively, to current or former affiliates.
 
NOTE I -- SIGNIFICANT CUSTOMERS
 
     During the year ended December 31, 1997, approximately 30% of revenues were
generated from current or former affiliated customers. Except for six rigs under
long term contracts with Chesapeake, dayrates billed to affiliated customers
approximated those billed to nonaffiliated customers. During 1996, sales to two
customers were, respectively, 75% (inclusive of $798,000 attributable to
Chesapeake, which became an affiliate in December 1996) and 18% of drilling
revenues. During 1995, sales to one customer totaled 36% of drilling revenue.
 
NOTE J -- STOCKHOLDER'S EQUITY AND OPTIONS
 
     In December 1996, the Company issued 2,000,000 shares of Common Stock to
Anadarko for the operating assets of BDC, Anadarko's subsidiary. Further, the
Company issued 2,000,000 shares of Common Stock to Energy Spectrum for $10
million cash. The Company also acquired six drilling rigs and related equipment
by the issuance of 1,600,000 shares of Common Stock and put options on the
Company's common stock. The drilling rigs were recorded in accordance with
appraisals of the estimated fair value of the assets acquired ($9.5 million) and
the net deferred income tax liability assumed. The estimated fair value of the
put options are recorded as additional contributed capital to the Company.
 
     The Company executed in December 1996 certain drilling agreements to supply
six drilling rigs to Chesapeake at rates equal to defined comparable market
rates but not less than $5,000 per day per rig. The Company granted the operator
an option to purchase 2,000,000 shares of Common Stock at $6 per share, subject
to performance of the operator under the drilling agreement. The estimated fair
value of the options of $1,100,000 was recorded as additional paid-in capital
and a deferred charge to be amortized over a twelve month period consistent with
the annual negotiations of contract terms. At December 31, 1997, the deferred
charge was fully amortized, and the Company and Chesapeake were unable to agree
on an appropriate rate adjustment related to these drilling agreements,
therefore the Company exercised its option to terminate the Chesapeake Drilling
Agreements.
 
     In February 1997, the Company sold 100,000 shares of Common Stock at $2.50
per share to the President of the Company, which are subject to the terms of a
Restricted Stock Award Agreement. Deferred compensation in the amount of
$250,000 was recorded related to this stock grant as the purchase price was
below the fair market value of the Company's Common Stock at the date of grant.
See -- Note "N".
 
     On December 10, 1996, the Company granted the issuer of the Term Loan (Note
G) warrants to immediately purchase up to 290,000 shares of the Company's Common
Stock at $8 per share or up to 300,000 shares at $8 per share when total
outstanding Common Stock exceeds 6,000,000 shares. The warrants expire at the
earlier of December 13, 2001 or eighteen months after completion of the initial
public stock offering by the Company. The warrant holder can also elect to
receive in stock the excess of the stock market value over the warrant exercise
price. These warrants have an estimated fair value of $219,000, which has been
recorded as debt issue costs and is being amortized over the term of the loan.
 
     The Company purchased during May 1997, two drilling rigs from U.S. Rig &
Equipment, Inc. for cash and granted options to purchase 100,000 shares of
Common Stock at $8 per share.
 
     In connection with the issuance of Subordinated Notes executed in May 1997,
the Company issued 1,140,000 shares of Common Stock at $7 per share.
Additionally, the Company issued two series of detachable Warrants, designated
as Series A Warrants and Series B Warrants. The Series A Warrants are
                                      F-20

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
exercisable at a price of $.01 per share and the Series B Warrants are
exercisable at $7.50 per share. Both Warrants expire 72 months from issuance.
The Company issued Series A Warrants and Series B Warrants representing the
right to purchase 798,000 shares and 912,000 shares of Common Stock,
respectively. The fair market value of these warrants at the agreement closing
date was $6 million, $4,024,000 of which was attributable to the Subordinated
Notes. The warrant value applicable to the Subordinated Notes was allocated
between the Subordinated Notes and warrants and recorded as a discount to the
Subordinated Notes and additional paid in capital. The remaining discount to be
amortized at December 31, 1997 is approximately $429,000. The amortization of
this discount has been included in interest expense.
 
     In June 1997, the Company granted options to employees to purchase 59,600
shares of Common Stock at $8 per share. Deferred compensation in the amount of
$59,600 was recorded related to these stock options as the exercise price was
below the fair market value of the Company's Common Stock at the date of grant.
See -- Note "N". In November 1997, the Company granted options to employees and
executive officers to purchase 397,000 shares of Common Stock at $23 per share.
During 1996 and 1997, the Company issued stock options to three executive
officers pursuant to the 1997 Stock Option and Stock Award Plan to purchase
200,000, 50,000 and 50,000 shares of Common Stock, respectively, at an exercise
price of $5, $5 and $10 per share, respectively. Except for 10,000 options
exercised in April 1998, at an exercise price of $5 per share none of such
options has been exercised, and all of such options remain outstanding.
 
     In October 1997, the Company consummated the Chesapeake Transactions,
resulting in the cancellation of the Chesapeake Option, the payment to the
Company of $9 million in cash by Chesapeake, the redemption of the $18 million
principal amount of Subordinated Notes held by Chesapeake for an aggregate cash
payment by the Company of $18.2 million and the issuance of 3,194,000 shares of
Common Stock to Chesapeake.
 
     At the August 19, 1997 Board of Directors meeting, the number of authorized
shares of Common Stock was increased from 10,000,000 to 100,000,000 and the
number of authorized shares of preferred stock was increased from 2,000,000 to
20,000,000. Additionally, a two-for-one stock split effected as a stock dividend
on August 22, 1997 was approved. All stock option data, per share earnings and
references to common stock have been restated to give effect to the stock split.
 
     On July 31, 1997, Energy Spectrum exercised in full its Series A Warrants,
at a price of $0.01 per share, for 98,000 shares of Common Stock.
 
     In April 1998, the Company redeemed in full the $2.52 million principal
amount of Subordinated Notes issued to Energy Spectrum together with accrued
interest of $47,740. In connection therewith, Energy Spectrum waived its rights
to require the Company to redeem the Subordinated Notes at 110% of par value.
This redemption coupled with the redemption of $18 million principal amount of
Subordinated Notes from Chesapeake at the time of the Initial Public Offering,
leaves no Subordinated Notes outstanding.
 
NOTE K -- COMMITMENTS AND CONTINGENCIES
 
     The Company has entered into two year employment agreements with three
executive officers, which provide for the payment of the remaining term of each
agreement upon a change of control. As of September 30, 1998, benefits under
such agreements, assuming a change of control, would aggregate approximately
$134,580.
 
     As of September 30, 1998, the Company had construction commitments totaling
approximately $500,000 for rigs in various stages of refurbishment.

     A shortage of drill pipe exists in the contract drilling industry in the
United States. This shortage has caused the price of drill pipe to increase
significantly over the past 30 months and has required orders for new drill pipe
to be placed at least one year in advance of expected use. The price increase
and the delay in delivery has caused the Company to substantially increase
capital expenditures for drill pipe in recent months. In the event the shortage
continues, the Company may be unable to obtain the drill pipe required to expand
its contract drilling operations. The Company has committed approximately $1.5
million for drill pipe orders at September 30, which is subject to cancellation
without penalty 90 days prior to the scheduled delivery date.
 
NOTE L -- SUBSEQUENT EVENTS
 
     A purported class action lawsuit is pending against the Company, certain
directors and officers of the Company, the managing underwriters of the Initial
Public Offering, and certain current and former stockholders of the Company,
alleging violations of federal securities laws in connection with the Initial
Public Offering. The lawsuit, Yuan v. Bayard Drilling Technologies, Inc., et al.
("Yuan"), was filed on February 3, 1998 in the United States District Court for
the Western District of Oklahoma. The principal plaintiff in Yuan is Tom Yuan.
The defendants in this case include the Company, Chesapeake, Energy Spectrum
LLC, James E. Brown, David E. Grose, Carl B. Anderson, III, Merrill A. Miller,
Jr., Sidney L. Tassin, Lew O. Ward, Mike Mullen, Roy T. Oliver, Donaldson,
Lufkin & Jenrette Securities Corporation, Lehman Brothers, Inc., Prudential
Securities, Inc., Rauscher Pierce Refsnes, Inc. (a predecessor to Dain Rauscher
Incorporated) and Raymond James & Associates, Inc.
 
     The plaintiffs in this lawsuit purport to sue on their own behalf and on
behalf of all persons who purchased shares of Common Stock on or traceable to
the Initial Public Offering. In the lawsuit, plaintiffs allege claims against
all defendants under the Securities Act. The plaintiffs allege that the
registration statement and prospectus for the Initial Public Offering contained
materially false and misleading information and omitted to disclose material
facts. In particular, the plaintiffs allege that such registration statement and
prospectus failed to disclose financial difficulties of Chesapeake, the
Company's largest customer, and the effects of such difficulties on Chesapeake's
ability to continue to provide the Company with substantial drilling contracts.
The petitions further allege that the Company failed to disclose pre-offering
negotiations with R.T. Oliver Drilling, Inc., whom the plaintiffs allege was a
related party, for the purchase of drilling rigs. In addition, the petitions
allege that the Company failed to disclose that its growth strategy required
costly refurbishment of older drilling rigs that would dramatically increase the
Company's costs, which could not be sustained by internally generated cash
flows. Plaintiffs are seeking rescission and damages.
 
     Two other suits, Khan v. Bayard Drilling Technologies, Inc., et al.
("Khan") and Burkett v. Bayard Drilling Technologies, Inc., et al. ("Burkett"),
which were filed in District Court in and for Oklahoma County, State of Oklahoma
on January 14, 1998 and February 2, 1998, respectively, and alleged essentially
the same claims as Yuan, were dismissed without prejudice in May 1998 on a joint
application filed by all parties. The plaintiffs in Khan and Burkett, along with
others, have been appointed as lead plaintiffs in the Yuan federal court suit,
now styled to include the other lead plaintiffs, as Yuan, et al. A motion to
dismiss the claims in this lawsuit has been filed by the Company and the other
defendants and is currently pending before the court.
 
     The Company is also involved in other litigation arising from time to time
in the ordinary course of its business, including workers' compensation claims
and disputes arising out of its drilling activities. Such disputes include a
claim filed against the Company and Marathon Oil Company on November 13, 1998 in
the District Court of Washita County in the State of Oklahoma. Eldred L. and
Patricia A. Schneberger, the plaintiffs in this lawsuit, seek an order of
abatement and actual, consequential and punitive damages for losses allegedly
incurred in connection with a drilling project that utilized one of the
Company's rigs.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     The Company believes the allegations in the lawsuits referenced above are
without merit and is defending vigorously the claims brought against it. The
Company is unable, however, to predict the outcome of these lawsuits or the
costs to be incurred in connection with their defense and there can be no
assurance that this litigation will be resolved in the Company's favor. An
adverse result or prolonged litigation could have a material adverse effect on
the Company's financial position or results of operations.
 
     Since the Consolidation Transactions and the Initial Public Offering of
11,040,000 shares of Common Stock, par value $0.01 per share of the Company,
which was completed in November 1997, and prior to December 31, 1997, the
Company agreed to purchase six additional rigs from R.T. Oliver for
approximately $14 million in cash. The Oliver Acquisition was completed on
January 9, 1998. The Company expects to refurbish and purchase complementary
equipment, including drill pipe, for these rigs at an aggregate cost of
approximately $28 million.
 
NOTE M -- EMPLOYEE BENEFIT PLAN
 
     The Company has a profit sharing plan for certain eligible employees who
have attained the age of 21 and completed at least one year of service.
Participants may contribute up to 15% (20% prior to October 1997) of
compensation for any plan year. The Company's discretionary contribution is
based on the participants' total years of service. The Company has made
contributions of approximately $283,000 through September 30, 1998.
 
NOTE N -- BENEFIT AND COMPENSATION PLAN
 
     In April 1997, the Board of Directors approved the adoption of an Employee
Stock Plan ("the Plan") whereby 1,600,000 shares of Common Stock are authorized
for issuance under the Plan to officers and employees. The Plan permits the
issuance of qualified or nonqualified stock options, as well as granting of
certain other awards, including shares of restricted stock. Options granted
become vested at the rate of 20% per year one year after being granted, with the
options expiring six years from the original grant date. The exercise price for
options granted through December 31, 1997 was based on the Company's estimate of
the fair market value on the date of the grant. Through December 31, 1997,
756,600 options and 100,000 shares of restricted stock (denoted below) were
issued under the Plan, 40,000 of which were exercisable at December 31, 1997 at
a weighted average exercise price of $5.
 
     Activity pertaining to the Plan is as follows:

     The fair value of each option granted is estimated using the Black-Scholes
model. This model includes, among others, a variable of stock volatility. As the
Company has not established a significant trading history, the volatility used
in the model was .40 for options granted through June 30, 1997 and .43 for
options granted since July 1, 1997 based on volatility of the stock price of a
similar entity that has been publicly traded for several years. Dividend yield
was estimated to remain at zero with risk free interest rates ranging between
5.72 and 6.31 percent. As there is no prior experience available to use in
estimating an expected life for the options, an average of the time between the
vesting and expiration dates of the options was used in determining the expected
lives of the options ranging from 3.5 to 5.5 years. Fair value of options
granted during 1997 and 1996 under the Plan were $4.6 million and $416,000,
respectively.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors
Bayard Drilling Technologies, Inc.
 
     We have audited the accompanying balance sheets of Trend Drilling Company
as of December 31, 1996 and 1995, and the related statements of operations,
stockholder's equity, and cash flows for each of the three years in the period
ended December 31, 1996. These financial statements are the responsibility of
the Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respect, the financial position of Trend Drilling Company as of
December 31, 1996 and 1995, and the results of its operations and its cash flows
for each of the three years in the period ended December 31, 1996, in conformity
with generally accepted accounting principles.

                       NOTES TO THE FINANCIAL STATEMENTS
   INFORMATION RELATING TO THE FOUR MONTHS ENDED APRIL 30, 1997 IS UNAUDITED
 
(A) NATURE OF OPERATIONS
 
     Trend Drilling Company (the "Company"), an Oklahoma corporation, began
operations in 1981. The Company provides contract drilling services in the
Mid-Continent region of the United States. The Company's customers are primarily
independent oil and gas companies.
 
     On February 13, 1997, the owner of the Company and sole stockholder,
entered into a stock purchase agreement (the "Agreement"), with Bayard Drilling
Technologies, Inc. ("Bayard") for the sale of the Company (the "Bayard
Acquisition"). The executed agreement states a purchase price of $18 million
plus shares of Bayard stock, adjusted for changes in working capital as of the
closing date compared to December 31, 1996.
 
(B) SUMMARY OF SIGNIFICANT ACCOUNT POLICIES
 
REVENUE RECOGNITION
 
     The Company recognizes revenue and expenses on dayrate contracts as the
drilling progresses (percentage-of-completion method). For footage and turnkey
contracts, the Company recognizes the revenue and expenses upon completion of
the well (completed-contract method).
 
     Revenue earned of $279,390, but not billed, is included in accounts
receivable at December 31, 1996.
 
CASH AND CASH EQUIVALENTS
 
     For purposes of the balance sheet, the Company considers cash equivalents
to be all instruments that had a remaining maturity of three months or less at
the date of purchase.
 
PROPERTY, PLANT AND EQUIPMENT
 
     Property, plant and equipment is recorded at cost. Depreciation of
property, plant and equipment is determined primarily on the straight-line
method over the estimated useful lives of the assets at the following rates:
 
<TABLE>
<CAPTION>
                                                              YEARS

Drilling rigs and related equipment.........................   5-14
Vehicles....................................................      5

</TABLE>
 
     Upon retirement or disposal, the related cost and accumulated depreciation
are removed from the accounts and any gain or loss is included in operations.
Repairs and maintenance, which extend the useful life of property, plant and
equipment, are capitalized.
 
GOODWILL
 
     The excess of the purchase price over the fair value of assets acquired is
amortized on the straight-line method over five years. Amortization expense was
$24,000 for the years-ended December 31, 1996, 1995 and 1994.

                NOTES TO THE FINANCIAL STATEMENTS -- (CONTINUED)
 
INCOME TAXES
 
     The Company accounts for income taxes in accordance with Statement of
Financial Accounting Standards No. 109, "Accounting for Income Taxes" ("SFAS No.
109"). Accordingly, deferred taxes are determined based on the difference
between the financial statement and tax bases of assets and liabilities using
the enacted tax rate in effect in the years in which the differences are
expected to reverse. Deferred tax expense represents the change in the deferred
tax liability balance.
 
CONCENTRATIONS OF CREDIT RISK
 
     Financial instruments which potentially subject the Company to
concentrations of credit risk consist primarily of trade receivables with oil
and natural gas companies. For the years ended December 31, 1996 and 1995 over
ninety-five percent of the Company's trade receivables were from ten or less
customers. These customers also represented 63%, 51% and 54% of total revenues
for 1996, 1995 and 1994, respectively.
 
     At December 31, 1996 and 1995, the Company had deposits in domestic banks
in excess of federally insured limits of approximately $467,000 and $348,000,
respectively.
 
ACCOUNTING ESTIMATES
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts for certain revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
INTERIM FINANCIAL STATEMENTS AND DISCLOSURES
 
     In the opinion of management, the unaudited interim financial statements
for the period ended April 30, 1997 and unaudited interim financial statement
disclosures subsequent to December 31, 1996 include all adjustments, consisting
of normal recurring accruals, necessary to present fairly the Company's results
of operations for the four months ended April 30, 1997.
 
(C) PROPERTY, PLANT AND EQUIPMENT
 
     Property, plant and equipment consist of the following at December 31,

</TABLE>
 
     On March 26, 1996, the Company entered into a term loan (the "Note") of
$3,098,058, which consolidated all of the Company's bank borrowings into one
term loan. At December 31, 1996, long-term debt consisted of borrowings under
this note of $1,755,437 which bears an interest rate at the prime rate, adjusted
quarterly (8.25% at December 31, 1996). The Note contains a subjective
acceleration clause which allows the lender to demand payment of the Note when
the lender, at its sole discretion, determines that the Note is impaired.
However, the Note has been classified based on the scheduled maturities in the
accompanying balance sheet as management does not believe such impairment has
occurred. The Note requires the maintenance of financial reporting requirements
and annual personal financial statements from the owner of the Company.
 
     The Note requires monthly payments of principal and interest in amounts
sufficient to repay borrowings at maturity on March 26, 2001. The Note is
collateralized by Accounts Receivable and Property, Plant and Equipment and is
personally guaranteed by the owner of the Company.
 
     At December 31, 1995, long-term debt consisted of borrowings under four
bank notes with an aggregate amount of $3,213,413 which bore interest at a rate
of 1% over prime (which was 8.75% on December 31, 1995).
 
     At December 31, 1996, the aggregate scheduled yearly maturities on
long-term obligations are as follows:

(F) RELATED PARTIES
 
     The Company has several affiliates in the oil and gas industry with which
the Company does business throughout the year. The type of transactions with
these related parties varies from the Company drilling wells for affiliates to
affiliates moving rigs from one well site to another, as well as receiving
certain administrative support for which the Company was not billed (i.e.,
computer support).
 
     As of December 31, 1996 and 1995, the Company had trade receivables with
related parties in the amount of $375,016 and $32,633, respectively, and trade
payables with related parties of $168,169 and $505,426, respectively.
 
     For the period ended December 31, 1996, 1995 and 1994 the Company had
revenues of $462,535, $917,743 and $1,422,658, respectively and expenses of
$2,121,975, $2,003,356 and $1,660,169, respectively, with related parties.
 
     The Company leases office space from an affiliate. For the years ended
December 31, 1996, 1995 and 1994, the Company paid rent of approximately
$10,000.

    INFORMATION RELATING TO THE FIVE MONTHS ENDED MAY 31, 1997 IS UNAUDITED
 
(A) NATURE OF OPERATIONS
 
     Ward Drilling Company (the "Company"), an Oklahoma corporation, began
operations in 1981. The Company provides contract drilling services in the
Mid-Continent region of the United States for independent oil and gas companies.
 
     In May 1997, the Company's parent, L.O. Ward Revocable Trust transferred
all the fixed assets of the Company into WD Equipment L.L.C. in anticipation of
the sale of these assets to Bayard Drilling Technologies, Inc. ("Bayard"), which
was consummated on May 31, 1997 (the "Bayard Acquisition"). The Company and
Bayard agreed to a purchase price of approximately $8 million plus 400,000
shares of Bayard stock plus warrants to purchase up to 200,000 shares of Bayard
stock in exchange for the purchase of WD Equipment L.L.C.
 
(B) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
REVENUE RECOGNITION
 
     The Company recognizes revenue and expenses on dayrate contracts as the
drilling progresses (percentage-of-completion method). For turnkey and footage
contracts, the Company recognizes the revenue and expenses upon completion of
the well (completed-contract method).
 
CASH AND CASH EQUIVALENTS
 
     The Company considers cash equivalents to be all instruments that had a
remaining maturity of three months or less at the date of purchase.
 
EQUIPMENT
 
     Equipment is recorded at cost. Depreciation on drilling equipment is
determined using the units-of-production method based upon management's
estimates of remaining drilling days by rig. Depreciation on all other equipment
is determined using the straight-line method over the estimated useful lives of
the assets ranging from three to seven years. Upon retirement or disposal, the
related cost and accumulated depreciation are removed from the accounts and any
gain or loss is included in operations.
 
     The costs of major repairs and overhauls which extend the useful life of
drilling equipment are capitalized by charges to the allowance for accumulated
depreciation. Other additions and improvements are charged to the applicable
equipment account.
 
INCOME TAXES
 
     The Company is an electing S corporation for federal and state income tax
purposes. The Company's taxable income or loss will be included in its
stockholder's income tax return. Accordingly, no provision for income taxes has
been included in these financial statements.
 
CONCENTRATIONS OF CREDIT RISK
 
     Financial instruments which potentially subject the Company to
concentrations of credit risk consist primarily of trade receivables with oil
and natural gas companies. At December 31, 1996 over ninety-eight percent of the
Company's trade receivables were from four customers. For the year ended
December 31, 1996 the ten largest customers account for over 96% of total
revenues.
 
     At December 31, 1996 the Company had deposits in domestic banks in excess
of federally insured limits of approximately $156,000.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
ACCOUNTING ESTIMATES
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts for certain revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
(C) NOTE PAYABLE TO BANK
 
     The Company has available a line of credit with a bank for $500,000 which
expires in March 1998. The line of credit is collateralized by inventory,
accounts receivable, and other miscellaneous assets. Interest is at the bank's
base rate plus one percent (9.25% and 9.5% at December 31, 1996 and 1995,
respectively.) Upon consummation of the sale of the Company on May 31, 1997,
this line of credit was extinguished.
 
(D) RELATED PARTIES
 
     The Company conducts drilling activities for companies owned or controlled
by L.O. Ward, one of the trustees of the L.O. Ward Revocable Trust (the Related
Parties); however no drilling activities were conducted for the Related Parties
in 1996.
 
     General and administrative expense in the accompanying statement of
operations is net of management fee income received from one of the Related
Parties aggregating $10,320 in 1996.
 
     The Company allocates office space and administrative expenses directly to
Related Parties. Amounts allocated under this arrangement aggregated
approximately $25,000 for 1996.
 
     The Company paid approximately $75,000 in 1996 to one of the Related
Parties for services which includes finding drilling contracts for the Company
and certain other administrative services. Certain expenses incurred by the
Related Parties and attributable to the Company's operations are not billed to
the Company.
 
     Accounts receivable at December 31, 1996 included $8,446 of receivables
from affiliated entities. Accounts payable at December 31, 1996 included
$241,233 owed to affiliated entities.
 
(E) EMPLOYMENT AGREEMENTS
 
     The Company has issued stock appreciation rights to certain employees which
may entitle them to receive bonuses. These bonuses are based on net income and
the ratio of stock appreciation rights owned by the employees to total
outstanding shares of common stock at year end. Ninety-nine stock appreciation
rights were outstanding at December 31, 1996. A bonus payment of approximately
$37,500 was payable to employees at December 31, 1996.
 
(F) SAVINGS PLAN
 
     The Company participates in a salary deferral retirement plan which is
available to substantially all employees. Participants in the plan may make
contributions to the plan, with the Company matching up to 25% of the employee's
basic contribution. The basic contribution cannot exceed 5% of the employee's
base salary. Total contributions by the Company were approximately $10,000 in
1996.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
(G) CONTINGENCIES
 
     The Company maintains a self insurance plan for workers' compensation and
is liable for claims up to $400,000 per-occurrence. The Company is involved in
legal actions arising out of workers' compensation claims. In the opinion of
management, the ultimate disposition of these matters will not have a material
adverse effect on the Company's financial position. Total expense for workers'
compensation was approximately $335,000 in 1996, and accrued liabilities
included a reserve for unpaid and incurred but not reported claims of $310,000
at December 31, 1996.

six-month period ended December 31, 1996 and the years ended June 30, 1996 and
1995. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Bonray Drilling Corporation

                31, 1996 AND YEARS ENDED JUNE 30, 1996 AND 1995
 
   INFORMATION RELATING TO THE NINE-MONTH PERIOD ENDED SEPTEMBER 30, 1997 IS
                                   UNAUDITED
 
1. BASIS OF FINANCIAL STATEMENTS AND SIGNIFICANT ACCOUNTING POLICIES
 
  Nature of Operations
 
     Bonray Drilling Corporation (the "Company") is engaged in domestic onshore
contract drilling of oil and gas wells. The Company currently owns and has
available for operation fifteen drilling rigs located in Oklahoma, having depth
capabilities ranging from 7,000 to 25,000 feet.
 
     On February 10, 1997, substantially all of the Company's shares of
outstanding common stock were purchased by DLB Oil & Gas, Inc. ("DLB") for $30
per share or approximately $12,700,000. As a result of the completed
transaction, the Company became a subsidiary of DLB. Effective on the date of
the acquisition, the Company changed its fiscal year end from June 30 to
December 31 to correspond with the year end of DLB.
 
     The transaction was accounted for as a purchase using push down accounting
treatment. This resulted in a step up in the basis of the acquired assets of
approximately $6.3 million, the establishment of approximately $1.5 million of
deferred income taxes and the elimination of the previously recorded balance of
accumulated depreciation and amortization. Additionally, the accumulated deficit
of $4,858,000 was eliminated as a result of a new basis established for the
acquired assets and liabilities.
 
  Cash and Cash Equivalents
 
     Cash and cash equivalents include cash deposits in banks and short-term
investments with original maturities of three months or less from the date of
purchase by the Company.
 
  Contract Drilling Operations
 
     Revenue earned from footage and turnkey contracts is recognized by the
completed contract method, while revenue earned from daywork contracts is
recognized by the percentage-of-completion method. Provision is made for the
entire amount of expected losses on contracts, if any, in the period in which
such losses are first determined.
 
  Valuation of Properties and Equipment
 
     Drilling equipment is stated at amounts representing historical cost prior
to the February 10, 1997 acquisition by DLB (pushed-down cost thereafter)
adjusted by prior year write-downs based on the expected future economic value
of such equipment. This value was determined by projecting the estimated future
undiscounted cash flows generated by drilling equipment based on the Company's
historical utilization rates and profit margins as well as consideration of the
economic conditions of the industry. The Company continues to review these
assets for possible impairment based on expected future cash flows and other
available information and has determined that no impairment in the value of the
assets exists at September 30, 1997, December 31, 1996 or June 30, 1996 or 1995.
However, due to the uncertainty of such factors it is reasonably possible that
the estimated future cash flows may change. Additions to drilling equipment,
land, buildings and other equipment are reported at cost.

THE ACQUISITION OF BONRAY DRILLING CORPORATION BY DLB WAS ACCOUNTED FOR USING
THE PURCHASE METHOD OF ACCOUNTING. ACCORDINGLY, THE PURCHASE PRICE WAS
"PUSHED-DOWN" AND RECORDED IN THE ACCOMPANYING FINANCIAL STATEMENTS WHICH
AFFECTS THE COMPARABILITY OF THE SEPTEMBER 30, 1997 FINANCIAL POSITION, RESULTS
OF OPERATIONS AND CASH FLOWS.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
  Depreciation
 
     Depreciation of drilling equipment is computed on an operating day basis
(net of estimated salvage value), except for drilling rigs and related equipment
which are "mothballed" or otherwise not expected to be used for an extended
period of time. During the year ended June 30, 1996, there was a decrease in the
estimated salvage value of these inactive drilling rigs and equipment. As a
result, depreciation on this equipment was increased during the year ended June
30, 1996 to reduce the net book value of these assets to their estimated salvage
value. Depreciation recorded on these inactive rigs and equipment was $269,000
and $36,000 for the years ended June 30, 1996 and 1995, respectively (none for
the six-month period ended December 31, 1996). The net book value of such
drilling equipment is $457,000, which approximates the estimated salvage value
of the equipment at December 31, 1996.
 
     Depreciation of buildings and other equipment is computed by the
straight-line method over the estimated useful lives of the assets.
 
  Income (Loss) Per Share
 
     Income (loss) per share is computed on the basis of weighted average number
of shares of common stock and dilutive common stock equivalents outstanding.
 
  Credit Risk
 
     The Company operates its rigs in the state of Oklahoma and grants credit,
which is generally unsecured, to its customers (Note 5). At December 31, 1996,
approximately 90% of the Company's accounts receivable were from five customers.
The Company has not experienced any significant credit losses in the six-month
period ended December 31, 1996 or the nine-month period ended September 30,
1997, or the years ended June 30, 1996 or 1995 and is not aware of any
significant uncollectible accounts at December 31, 1996.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
  Fair Value of Financial Instruments
 
     The following methods and assumptions were used by the Company in
estimating their fair values of financial instruments: Cash and cash equivalents
are estimated to have a fair value approximating the carrying amount due to the
short maturity of those instruments. Notes payable have variable interest rates
with carrying values approximating fair values.
 
  Interim Financial Statements and Disclosures
 
     In the opinion of management, the unaudited interim financial statements as
of and for the nine-month period ended September 30, 1997 and unaudited interim
financial statement disclosures subsequent to December 31, 1996 include all
adjustments, consisting of normal recurring accruals and push-down adjustments,
necessary to present fairly the Company's financial position as of September 30,
1997 and

results of operations and cash flows for the nine-month period ended September
30, 1997. Results for the period ended September 30, 1997 are not necessarily
indicative of the results to be expected for the entire year.
 
2. INCOME TAXES
 
     Deferred income taxes reflect the net tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes. Significant components of
the Company's deferred tax liabilities and assets as of December 31, 1996 and
June 30, 1996 are as follows (dollars in thousands):

     The deferred tax assets and liability are offset and, therefore, no
deferred tax asset or liability is reflected in the Company's balance sheets at
December 31, 1996 and June 30, 1996.
 
     The difference between the amount of the provision for income taxes and the
amount which would result from the application of the statutory rate to income
(loss) before provision for income taxes is analyzed as follows (dollars in
thousands):

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
3. NOTES PAYABLE
 
     In July 1997, the Company entered into a $23 million credit agreement in
connection with which substantially all of the Company's assets were pledged as
collateral. Additionally, the company's parent, DLB, pledged as collateral all
of the outstanding common stock of the Company. Upon consummation of the
acquisition of the Company by Bayard, the shares of common stock of the Company
were released by the lender and the shares of common stock of Bayard acquired by
DLB in the acquisition were pledged in lieu thereof. In connection with the
acquisition, the note payable to Lehman Commercial Paper, Inc. was transferred
to DLB, thereby eliminating the note receivable from DLB.
 
     During the six-month period ended December 31, 1996, the Company acquired
drilling equipment with the proceeds from two notes with a bank in the amounts
of $245,000 and $150,000, respectively. The notes are payable in monthly
installments of principal and interest in the amounts of $21,415 and $13,102,
respectively, until paid in full with interest at a rate of  1/2% above the
national prime lending rate (aggregate rate of 8.75% at December 31, 1996) and
are secured by the equipment purchased as well as other specific drilling
equipment owned by the Company. The balances of the two notes at December 31,
1996 are $205,000 and $138,000, respectively, all of which is due within one
year. During 1997, all of these outstanding note balances were retired by DLB.
 
     The Company has a revolving line of credit agreement (the "credit
agreement") with a bank. Credit availability is subject to a monthly borrowing
base determination calculated as 75% of the Company's accounts receivable less
than 90 days old, not to exceed $750,000. At December 31, 1996, no borrowings
were outstanding under the revolving line of credit ($555,000 outstanding at
June 30, 1996). The credit agreement, which expired November 3, 1997, provided
for monthly interest payments, which accrued at a rate of 1/2 of 1% over the
lender's national prime rate (aggregate rate of 8.75% at December 31, 1996).
Outstanding advances and accrued interest are due in full upon expiration of the
credit agreement. The credit agreement is secured by the Company's accounts
receivable.
 
     During the year ended June 30, 1995, the Company acquired drilling and
other equipment by issuing a note payable to the seller of the equipment. The
$189,000 balance on the note at June 30, 1996 was paid by the Company during the
six-month period ended December 31, 1996.
 
4. WORKERS' COMPENSATION
 
     The Company is covered by a workers' compensation insurance plan for its
employees under which the Company is responsible for claims up to $100,000 per
incident.
 
     At December 31, 1996 and June 30, 1996, the Company has an estimated net
liability for accrued workers' compensation costs totaling $843,000 and $521,000
respectively. Under the plan, the Company is to reimburse the administrator for
costs as the administrator pays those costs, normally over a five-year period.
Accordingly, at both December 31, 1996 and June 30, 1996, $75,000 is classified
as due after one year, in the accompanying balance sheets.
 
     Total workers' compensation costs incurred by the Company were $538,000 for
the six-month period ended December 31, 1996 and $597,000 and $979,000 for the
years ended June 30, 1996 and 1995, respectively, and were based on actual and
estimated claims incurred. For the six-month period ended December 31, 1996 and
the year ended June 30, 1996, workers' compensation expense was reduced by
$38,000 and $48,000 ($0.09 and $0.11 per share, respectively) for changes in
estimates of claims relating

to prior fiscal years. Workers' compensation expense for the year ended June 30,
1995 was increased by $40,000 ($0.09 per share), for changes in the estimated
costs of claims that occurred in prior fiscal years.
 
     The Company accrues losses for workers' compensation based on management's
estimate of the expected cost of claims incurred. The estimates are based upon
known information, historical experiences and consideration of risk reduction
techniques, when applicable, such as stop loss insurance on individual claims.
Due to uncertainties inherent in the estimation process, it is reasonably
possible that these estimates will be revised in the near-term; however,
management does not expect that such changes will be material to the financial
position or results of operations of the Company.
 
5. MAJOR CUSTOMERS
 
     Contract drilling operations revenues include revenues from certain
customers, which individually account for 10% or more of contract drilling
operations revenues as follows (dollars in thousands):

6. SUBSEQUENT EVENTS
 
     On October 16, 1997, the Company was acquired by Bayard for 3,015,000
shares of common stock, par value $0.01 per share, of Bayard, subject to certain
working capital adjustments.
 
7. CONTINGENCIES
 
     During the normal course of business, the Company enters into agreements
and executes transactions that may result in a contingent liability to the
Company. At September 30, 1997, management does not believe such contingencies
would be material to the financial statements.

Merger") with the Secretary of State of the State of Delaware, in such form

as required by, and executed in accordance with the relevant provisions of,
Delaware Law. The Merger shall become effective at the time of filing of the
Certificate of Merger with the Secretary of State of the State of Delaware in
accordance with Delaware Law, or at such later time that the parties hereto
shall have agreed upon and designated in such filing as the effective time of
the Merger (the "Effective Time").
 
     1.3. Effect of the Merger. At the Effective Time, the effect of the Merger
shall be as provided in the applicable provisions of Delaware Law. Without
limiting the generality of the foregoing, and subject thereto, at the Effective
Time, except as otherwise provided herein, all the property, rights, privileges,
powers and franchises of Merger Sub and the Company shall vest in the Surviving
Corporation, and all debts, liabilities and duties of Merger Sub and the Company
shall become the debts, liabilities and duties of the Surviving Corporation.
 
     1.4. Certificate of Incorporation; Bylaws. At the Effective Time, each of
the Restated Certificate of Incorporation, as amended, and the Amended and
Restated Bylaws of the Company shall be amended and restated in its entirety to
read as set forth in Exhibit 1.4A and Exhibit 1.4B, respectively, and as so
amended shall be the Restated Certificate of Incorporation and Bylaws of the
Surviving Corporation.
 
     1.5. Directors and Officers of Merger Sub. The directors of Merger Sub
immediately prior to the Effective Time shall be the directors of the Surviving
Corporation, each to hold office in accordance with the Restated Certificate of
Incorporation and Bylaws of the Surviving Corporation, and the officers of the
Company immediately prior to the Effective Time shall be the officers of the
Surviving Corporation, in each case until their respective successors are duly
elected or appointed and qualified.
 
                                   ARTICLE II
 
               CONVERSION OF SECURITIES; EXCHANGE OF CERTIFICATES
 
     2.1. Conversion of Securities. At the Effective Time, by virtue of the
Merger and without any action on the part of Merger Sub, the Company or the
holders of any of the following securities:
 
          (a) Each share of common stock, par value $.01 per share, of the
     Company ("Company Common Stock") issued and outstanding immediately prior
     to the Effective Time (excluding any treasury shares held by the Company or
     any of its Subsidiaries, shares held by Parent or any of its Subsidiaries
     and Dissenting Shares (as defined in Section 2.4)), shall be converted into
     the right to receive (i) 0.3375 fully paid, non-assessable shares of common
     stock (the "Exchange Ratio"), par value $.10 per share, of Parent ("Parent
     Common Stock") and (ii) $0.30 in cash (the "Cash Consideration").
 
          (b) If between the date of this Agreement and the Effective Time the
     outstanding shares of Parent Common Stock or Company Common Stock shall
     have been changed into a different number of shares or a different class,
     by reason of any stock dividend, subdivision, reclassification,
     recapitalization, split, combination or exchange of shares or if a "Flip-In
     Event" or "Flip-Over Event" (each as defined under the Company Rights Plan
     (as defined in Section 4.2)) shall have occurred under the Company Rights
     Plan, the Exchange Ratio shall be correspondingly adjusted to reflect such
     stock dividend, subdivision, reclassification, recapitalization, split,
     combination or exchange of shares or event.
 
          (c) All such shares of Company Common Stock shall no longer be
     outstanding, shall automatically be canceled and retired and shall cease to
     exist, and each certificate previously evidencing any such shares shall
     thereafter represent the right to receive the Merger Consideration (as
     defined in Section 2.2(b)). The holders of such certificates previously
     evidencing such shares of Company Common Stock outstanding immediately
     prior to the Effective Time shall cease to have any rights with respect to
     such shares of Company Common Stock, except as otherwise provided herein or
     by law. Such certificates previously evidencing shares of Company Common
     Stock shall be exchanged for certificates evidencing whole shares of Parent
     Common Stock and payment of the Cash
 
                                       A-2
<PAGE>   151
 
     Consideration in accordance with the allocation procedures of this Section
     2.1 upon the surrender of such certificates in accordance with the
     provisions of Section 2.2, without interest. No fractional shares of Parent
     Common Stock shall be issued, and, in lieu thereof, a cash payment shall be
     made pursuant to Section 2.2(e).
 
          (d) Each share of Company Common Stock held in the treasury of the
     Company and each share of Company Common Stock owned by Parent or any
     direct or indirect wholly owned subsidiary of Parent or of the Company
     immediately prior to the Effective Time shall be canceled and extinguished
     without any conversion thereof and no payment shall be made with respect
     thereto.
 
          (e) Each share of common stock, par value $.10 per share, of Merger
     Sub issued and outstanding at the Effective Time shall be converted into
     one share of common stock of the Surviving Corporation.
 
     2.2. Exchange of Certificates.
 
          (a) Exchange Agent. As of the Effective Time, Parent shall deposit, or
     shall cause to be deposited, with First Chicago Trust Company of New York
     or such other bank or trust company designated by Parent and reasonably
     acceptable to the Company (the "Exchange Agent"), for the benefit of the
     holders of shares of Company Common Stock, for exchange in accordance with
     this Article II through the Exchange Agent (i) certificates evidencing such
     number of whole shares of Parent Common Stock equal to the Exchange Ratio
     multiplied by the number of shares of Company Common Stock outstanding
     (other than (x) shares described in Section 2.1(d) and (y) Dissenting
     Shares), (ii) an amount in cash equal to the Cash Consideration multiplied
     by the number of shares of Company Common Stock outstanding (other than (x)
     shares described in Section 2.1(d) and (y) Dissenting Shares) and (iii)
     additional cash in consideration of fractional shares as provided in
     Section 2.2(e) (such Parent Common Stock and cash being hereinafter
     referred to as the "Exchange Fund"). The Exchange Agent shall, pursuant to
     irrevocable instructions, deliver the Parent Common Stock and cash out of
     the Exchange Fund. Except as contemplated by Section 2.2(e) and (f) hereof,
     the Exchange Fund shall not be used for any other purpose.
 
          (b) Exchange Procedures. As soon as reasonably practicable after the
     Effective Time, Parent will instruct the Exchange Agent to mail to each
     holder of record of a certificate or certificates which immediately prior
     to the Effective Time evidenced outstanding shares of Company Common Stock
     (the "Certificates"), (i) a letter of transmittal (which shall specify that
     delivery shall be effected, and risk of loss and title to the Certificates
     shall pass, only upon proper delivery of the Certificates to the Exchange
     Agent and shall be in such form and have such other provisions as Parent
     may reasonably specify) and (ii) instructions for use in effecting the
     surrender of the Certificates in exchange for certificates evidencing
     shares of Parent Common Stock. Upon surrender of a Certificate for
     cancellation to the Exchange Agent together with such letter of
     transmittal, duly executed, and such other customary documents as may be
     required pursuant to such instructions, the holder of such Certificate
     shall be entitled to receive in exchange (A) an amount in cash and
     certificates evidencing that number of whole shares of Parent Common Stock,
     which such holder has the right to receive in respect of the shares of
     Company Common Stock formerly evidenced by such Certificate in accordance
     with Section 2.1, and (B) cash in lieu of fractional shares of Parent
     Common Stock to which such holder is entitled pursuant to Section 2.2(e)
     (such shares of Parent Common Stock and cash being collectively, the
     "Merger Consideration"), and the Certificate so surrendered shall be
     canceled. In the event of a transfer of ownership of shares of Company
     Common Stock which is not registered in the transfer records of the
     Company, a certificate evidencing the proper number of shares of Parent
     Common Stock may be issued in accordance with this Article II to a
     transferee if the Certificate evidencing such shares of Company Common
     Stock is presented to the Exchange Agent, accompanied by all documents
     required to evidence and effect such transfer and by evidence that any
     applicable stock transfer taxes have been paid. Until surrendered as
     contemplated by this Section 2.2, each Certificate (other than Certificates
     representing Dissenting Shares) shall be deemed at any time after the
     Effective Time to evidence only the right to receive, upon such surrender,
     the Merger
 
                                       A-3
<PAGE>   152
 
     Consideration. The Exchange Agent shall not be entitled to vote or exercise
     any rights of ownership with respect to the Parent Common Stock held by it
     from time to time hereunder, except that it shall receive and hold all
     dividends or other distributions paid or distributed with respect thereto
     for the account of the persons entitled thereto.
 
          (c) Distributions with Respect to Unexchanged Shares. No dividends or
     other distributions declared or made after the Effective Time with respect
     to Parent Common Stock with a record date after the Effective Time shall be
     paid to the holder of any unsurrendered Certificate with respect to the
     shares of Parent Common Stock evidenced thereby, and no other part of the
     Merger Consideration shall be paid to any such holder, until the holder of
     such Certificate shall surrender such Certificate, at which time, subject
     to the effect of applicable laws, there shall be issued to the holder (i)
     certificates evidencing whole shares of Parent Common Stock issued in
     exchange therefor, the amount of cash payable with respect to the Cash
     Consideration and the amount of any cash payable with respect to a
     fractional share of Parent Common Stock to which such holder is entitled
     pursuant to Section 2.2(e) and the amount of dividends or other
     distributions with a record date after the Effective Time then paid with
     respect to such whole shares of Parent Common Stock, and (ii) at the
     appropriate payment date, the amount of dividends or other distributions
     (without interest thereon), with a record date after the Effective Time but
     prior to surrender and a payment date occurring after surrender, payable
     with respect to such whole shares of Parent Common Stock. No interest shall
     be paid on any such amounts.
 
          (d) No Further Rights in Company Common Stock. All shares of Parent
     Common Stock issued and cash paid upon conversion of the shares of Company
     Common Stock in accordance with the terms of this Agreement shall be deemed
     to have been issued or paid in full satisfaction of all rights pertaining
     to such shares of Company Common Stock.
 
          (e) No Fractional Shares.
 
             (i) No certificates or scrip evidencing fractional shares of Parent
        Common Stock shall be issued upon the surrender for exchange of
        Certificates, and such fractional share interests will not entitle the
        owner thereof to vote or to any rights of a stockholder of Parent.
 
             (ii) Each holder of a Certificate having a fractional interest
        arising upon the conversion of such Certificate shall, at the time of
        surrender of the Certificate, be paid by the Exchange Agent an amount in
        cash equal to the value of such fractional interest based on the average
        closing price per share of Parent Common Stock as reported by The Wall
        Street Journal (Northeast edition) for the ten consecutive trading days
        ending on and including the fifth trading day prior to the Closing Date,
        appropriately adjusted for any stock splits, reverse stock splits, stock
        dividends, recapitalizations or other similar transactions. No interest
        shall be paid on any such amounts. All fractional shares to which a
        single record holder would be entitled shall be aggregated.
 
          (f) Termination of Exchange Fund. Any portion of the Exchange Fund
     which remains undistributed to the holders of Company Common Stock for one
     year after the Effective Time shall be delivered to Parent, upon demand,
     and any holders of Company Common Stock who have not then complied with
     this Article II shall thereafter look only to Parent for the Merger
     Consideration to which they are entitled.
 
          (g) No Liability. Neither Parent nor the Surviving Corporation shall
     be liable to any holder of shares of Company Common Stock for any shares of
     Parent Common Stock or cash (or dividends or distributions with respect
     thereto) delivered to a public official pursuant to any applicable
     abandoned property, escheat or similar law.
 
          (h) Lost Certificates. In the event any Certificate shall have been
     lost, stolen or destroyed, upon the making of an affidavit of that fact by
     the person claiming such Certificate to be lost, stolen or destroyed and,
     if required by the Surviving Corporation, the posting by such person of a
     bond in such reasonable amount as the Surviving Corporation may direct as
     indemnity against any claim that may
                                       A-4
<PAGE>   153
 
     be made against it with respect to such Certificate, the Exchange Agent
     will issue in exchange for such lost, stolen or destroyed Certificate the
     shares of Parent Common Stock, the Cash Consideration and cash in lieu of
     fractional shares, and unpaid dividends and distributions on shares of
     Parent Common Stock as provided above, deliverable in respect thereof
     pursuant to this Agreement.
 
     2.3. Stock Transfer Books. At the Effective Time, the stock transfer books
of the Company shall be closed and there shall be no further registration of
transfers of shares of Company Common Stock thereafter on the records of the
Company. On or after the Effective Time, any Certificates presented to the
Exchange Agent or Parent for any reason shall be canceled and exchanged for the
Merger Consideration.
 
     2.4. Dissenting Shares. Notwithstanding anything in this Agreement to the
contrary, shares of Company Common Stock that are issued and outstanding
immediately prior to the Effective Time and that are held by stockholders who
have properly exercised appraisal rights with respect thereto under Section 262
of Delaware Law (the "Dissenting Shares") shall not be converted into the right
to receive the consideration therefor specified in Section 2.1, but the holders
of Dissenting Shares shall be entitled to receive such payment as shall be
determined pursuant to Section 262 of Delaware Law; provided, however, that if
any such holder shall have failed to perfect or shall withdraw or lose the right
to appraisal and payment under Delaware Law, each such holder's shares of
Company Common Stock shall thereupon be deemed to have been converted as of the
Effective Time into the right to receive the consideration therefor specified in
Section 2.1, without any interest thereon, as provided in Section 2.2, and such
shares shall no longer be Dissenting Shares.
 
     2.5. Company Stock Options; Company Warrants.
 
          (a) At the Effective Time each outstanding Company Stock Option (as
     defined in Section 4.2) to purchase shares of Company Common Stock, by
     virtue of the Merger and without further action on the part of the Company
     or the holder of any Company Stock Option, shall be converted into an
     option to purchase Parent Common Stock ("Parent Stock Option") exercisable
     for that number of whole shares of Parent Common Stock equal to the product
     of the number of shares of Company Common Stock covered by Company Stock
     Option immediately prior to the Effective Time multiplied by the Exchange
     Ratio rounded up to the nearest whole number of shares of Parent Common
     Stock, and the per share exercise price for the shares of Parent Common
     Stock issuable upon the exercise of such Parent Stock Options shall be
     equal to the quotient determined by dividing (i) the amount obtained by
     subtracting (A) the Cash Consideration from (B) the exercise price per
     share of Company Common Stock specified for such Company Stock Option under
     the applicable Company Stock Option plan or agreement immediately prior to
     the Effective Time, by (ii) the Exchange Ratio (rounding the resulting
     exercise price up to the nearest whole cent). The date of grant of the
     Parent Stock Option shall be the date on which Company Stock Option was
     originally granted. Parent shall reserve for issuance the number of shares
     of Parent Common Stock that will become issuable upon the exercise of
     Parent Stock Options pursuant to this Section 2.5. The Parent Stock Options
     granted pursuant hereto shall have the same schedule of vesting and same
     period for exercise as applies to Company Stock Options granted prior to
     the date of this Agreement; provided, however, that, with respect to the
     employee holders of Company Stock Options identified in Section 4.2,
     paragraph 1 of the Company Disclosure Schedule (as defined in the first
     clause of Article IV) who are still employed by the Company immediately
     prior to the Effective Time, should such an employee holder be terminated
     by the Surviving Corporation without cause during the one-year period
     immediately following the Effective Time, then the number of Parent Stock
     Options received by such employee holder in exchange for such employee
     holder's Company Stock Options in accordance with this Section 2.5(a) shall
     immediately and fully vest upon such termination. As soon as practicable
     after the Effective Time, Parent shall file a registration statement on
     Form S-8 (or any successor form), or another appropriate form with respect
     to the shares of Parent Common Stock subject to such options and shall use
     its best efforts to maintain the effectiveness of such registration
     statement or registration statements for so long as such options remain
     outstanding. Except as otherwise expressly provided herein, the Parent
     Stock Options shall be subject to the terms and
                                       A-5
<PAGE>   154
 
     conditions of Parent's 1998 Employee Stock Option Plan or a similar plan,
     and except as otherwise contemplated by Parent and consistent with this
     Section 2.5(a), the form of stock option agreement shall be Parent's
     standard form as in effect on the date hereof. If Parent requests, Parent
     and the Company will negotiate in good faith to modify this Section 2.5(a)
     so that, in lieu of converting Company Stock Options into Parent Stock
     Options, Parent will adopt the Company Stock Option plans, subject to the
     changes in the terms of the Company Stock Options described above.
 
          (b) The Company shall (i) take all necessary action pursuant to the
     Company's stock option plans or otherwise and (ii) to the extent necessary
     under the terms of the applicable stock option plans and agreements, shall
     use its best reasonable efforts to cause the holders of Company Stock
     Options to execute any documents necessary, in each case, to effectuate the
     provisions of this Section 2.5.
 
          (c) At the Effective Time each outstanding Company Warrant (as defined
     in Section 4.2) to purchase shares of Company Common Stock, by virtue of
     the Merger and without further action on the part of the Company or the
     holder of any Company Warrant, shall remain outstanding on the same terms
     as in effect immediately prior to the Effective Time, but shall thereafter
     only be exercisable for (i) that number of whole shares of Parent Common
     Stock equal to the product of the number of shares of Company Common Stock
     covered by the Company Warrant immediately prior to the Effective Time
     multiplied by the Exchange Ratio rounded up to the nearest whole number of
     shares of Parent Common Stock, and (ii) that amount of cash equal to the
     product of the number of shares of Company Common Stock covered by the
     Company Warrant immediately prior to the Effective Time multiplied by the
     Cash Consideration. Parent shall reserve for issuance the number of shares
     of Parent Common Stock that will become issuable upon the exercise of the
     Company Warrants pursuant to this Section 2.5.
 
          (d) The Company shall (i) take all necessary action pursuant to the
     Company's warrant agreements or otherwise and (ii) to the extent necessary
     under the terms of the applicable Company Warrants, shall use its best
     reasonable efforts to cause the holders of Company Warrants to execute any
     documents necessary, in each case, to effectuate the provisions of this
     Section 2.5.
 
                                  ARTICLE III
 
            REPRESENTATIONS AND WARRANTIES OF PARENT AND MERGER SUB
 
     Except as set forth on the Disclosure Schedule delivered by Parent to the
Company prior to the execution of this Agreement (the "Parent Disclosure
Schedule"), each of Parent and Merger Sub jointly and severally represents and
warrants to the Company that:
 
     3.1. Organization, Qualification, Etc. Each of Parent and Merger Sub is a
corporation duly organized, validly existing and in good standing under the laws
of the State of Delaware and has the requisite corporate power and authority to
own its properties and assets and to carry on its business as it is now being
conducted and is duly qualified to do business and is in good standing in each
jurisdiction in which the ownership of its properties or the conduct of its
business requires such qualification, except for jurisdictions in which the
failure to be so qualified or in good standing would not, individually or in the
aggregate, have a Material Adverse Effect (as defined below) on Parent. As used
in this Agreement, any reference to a state of facts, event, change or effect
having a "Material Adverse Effect" on or with respect to Parent or the Company,
as the case may be, means (except as provided in the immediately following
sentence) a state of facts, event, change or effect that has had, or would
reasonably be expected to have, a material adverse effect on the business,
results of operations or financial condition of the applicable entity and its
Subsidiaries (as defined in Section 9.3(g)), taken as a whole, except for any
such state of facts, events, changes or effects that are attributable to changes
or developments in general economic conditions or the oil and gas or contract
drilling industries in general. In addition, it is expressly understood and
agreed that a Material Adverse Effect shall not be deemed to include (A) any
state of facts, events, changes or effects, or any anticipated state of facts,
events, changes or effects (including, but not limited to, any estimated or
anticipated operating losses or other adverse operating results), which prior to
or on
                                       A-6
<PAGE>   155
 
February 12, 1999 have been disclosed to or are known by the Company (in the
case of any state of facts, events, changes or effects affecting the Parent) or
the Parent (in the case of any state of facts, events, changes or effects
affecting the Company) or (B) any state of facts, events, changes or effects
which do not cause or are not reasonably expected to cause or result in actual
monetary loss which exceeds $75.0 million (in the case of Parent), or $7.5
million (in the case of the Company). The copies of Parent's Restated
Certificate of Incorporation and By-laws which have been delivered to the
Company are complete and correct and in full force and effect on the date
hereof. Each of Parent's Significant Subsidiaries (as defined in Section 9.3(f))
is a corporation duly organized, validly existing and (if applicable) in good
standing under the laws of its jurisdiction of incorporation or organization,
has the requisite power and authority to own its properties and to carry on its
business as it is now being conducted, and is duly qualified to do business and
is (if applicable) in good standing in each jurisdiction in which the ownership
of its property or the conduct of its business requires such qualification,
except for jurisdictions in which the failure to be so qualified or in good
standing (if applicable) would not, individually or in the aggregate, have a
Material Adverse Effect on Parent. All the outstanding shares of capital stock
of, or other ownership interests in, Parent's Significant Subsidiaries are
validly issued, fully paid and non-assessable and are owned by Parent, directly
or indirectly, free and clear of all liens, claims, charges or encumbrances,
except for restrictions contained in credit agreements and similar instruments
to which Parent is a party under which no event of default has occurred or
arisen. There are no existing options, rights of first refusal, preemptive
rights, calls or commitments of any character relating to the issued or unissued
capital stock or other securities of, or other ownership interests in, any
Significant Subsidiary of Parent.
 
     3.2. Capital Stock. The authorized stock of Parent consists of 200,000,000
shares of common stock, par value $.10 per share ("Parent Common Stock"),
10,000,000 shares of preferred stock, par value $.10 per share ("Parent
Preferred Stock"), and 8,000,000 shares of Class B Stock, par value $.10 per
share ("Parent Class B Stock"). As of August 4, 1998, 100,860,903 shares of
Parent Common Stock were issued and outstanding and no shares of Parent
Preferred Stock or Parent Class B Stock were issued or outstanding. All the
outstanding shares of Parent Common Stock have been validly issued and are fully
paid and non-assessable. As of August 4, 1998, there were no outstanding
subscriptions, convertible or exchangeable securities, options, warrants, calls,
rights or other arrangements or commitments obligating Parent to issue, deliver
or sell any shares of its capital stock or debt securities, or any securities of
any kind convertible into its capital stock, or obligating Parent to grant,
extend or enter into any such subscription, option, warrant, call, right or
other arrangement or commitment other than: (a) options and other rights to
receive or acquire 21,155,747 shares of Parent Common Stock granted on or prior
to August 4, 1998, pursuant to employee incentive or benefit plans, programs and
arrangements and non-employee director plans; (b) warrants to purchase 200,000
shares of Parent Common Stock issued to the former stockholders of an acquired
entity; and (c) rights to acquire shares of Parent Common Stock upon conversion
of Parent's 5% Convertible Subordinated Notes due May 15, 2006. Except for the
issuance of shares of Parent Common Stock pursuant to the options and other
rights referred to in clauses 3.2(a), (b) and (c), since August 4, 1998, no
shares of Parent Common Stock, Parent Preferred Stock or Parent Class B Stock
have been issued and no options, warrants or other securities convertible into
shares of capital stock of Parent have been issued or granted. The shares of
Parent Common Stock to be issued as consideration in the Merger are duly
authorized and, when issued in accordance with the terms of this Agreement, will
be validly issued, fully paid and nonassessable. Parent has not granted any
registration rights with respect to its securities that are currently
exercisable.
 
     3.3. Corporate Authority Relative to this Agreement; No Violation. Parent
has the corporate power and authority to enter into this Agreement and to carry
out its obligations hereunder. The execution and delivery of this Agreement and
the consummation of the transactions contemplated hereby have been duly and
validly authorized by the Board of Directors of Parent and no other corporate
proceedings on the part of Parent are necessary to authorize the consummation of
the transactions contemplated hereby. The Boards of Directors of Parent and
Merger Sub have determined that the transactions contemplated by this Agreement
are in the best interests of such entities and their respective stockholders.
This Agreement has been duly and validly executed and delivered by Parent and
Merger Sub and, assuming this Agreement
                                       A-7
<PAGE>   156
 
constitutes a valid and binding agreement of the Company, this Agreement
constitutes a valid and binding agreement of Parent and Merger Sub, enforceable
against them in accordance with its terms (except insofar as enforceability may
be limited by applicable bankruptcy, insolvency, reorganization, moratorium or
similar laws affecting creditors' rights generally, or by principles governing
the availability of equitable remedies). Neither Parent nor Merger Sub is
subject to or obligated under any charter, by-law or contract provision or any
license, franchise or permit, or subject to any order or decree, which would be
breached or violated by its executing or carrying out the transactions
contemplated by this Agreement, except for any breaches or violations which
would not, individually or in the aggregate, have a Material Adverse Effect on
Parent. Other than in connection with or in compliance with the provisions of
Delaware Law, the Securities Act of 1933, as amended (the "Securities Act"), the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), the
Hart-Scott-Rodino Antitrust Improvement Act of 1976, as amended (the "HSR Act"),
Section 4043 of ERISA (as defined in Section 3.8) and the securities or blue sky
laws of the various states (collectively, the "Parent Required Approvals"), no
authorization, consent or approval of, or filing with, any governmental body or
authority is necessary for the consummation by Parent of the transactions
contemplated by this Agreement, except for such authorizations, consents,
approvals or filings, the failure to obtain or make which would not,
individually or in the aggregate, have a Material Adverse Effect on Parent or
substantially impair or delay the consummation of the transactions contemplated
hereby.
 
     3.4. Reports and Financial Statements. Parent has previously furnished to
the Company true and complete copies of: (a) Parent's Annual Reports on Form
10-K filed with the Securities and Exchange Commission (the "SEC") for each of
the years ended September 30, 1995 through 1997; (b) Parent's Quarterly Reports
on Form 10-Q filed with the SEC for the quarters ended December 31, 1997, March
31, 1998 and June 30, 1998; (c) each definitive proxy statement filed by Parent
with the SEC since September 30, 1995; (d) each final prospectus filed by Parent
with the SEC since September 30, 1995, except any final prospectus on Form S-8;
and (e) all Current Reports on Form 8-K filed by Parent with the SEC since
October 1, 1997. As of their respective dates, such reports, proxy statements
and prospectuses (collectively, the "Parent SEC Reports") (i) complied as to
form in all material respects with the applicable requirements of the Securities
Act, the Exchange Act and the rules and regulations promulgated thereunder and
(ii) did not contain any untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances under which they were made, not
misleading. Except to the extent that information contained in any Parent SEC
Report has been revised or superseded by a later filed Parent SEC Report, none
of the Parent SEC Reports contains any untrue statement of a material fact or
omits to state any material fact required to be stated therein or necessary in
order to make the statements therein, in light of the circumstances under which
they were made, not misleading. The audited consolidated financial statements
and unaudited consolidated interim financial statements included in the Parent
SEC Reports (including any related notes and schedules) have been prepared in
accordance with and fairly present the financial position of Parent and its
consolidated subsidiaries as of the dates thereof and the results of operations
and cash flows for the periods or as of the dates then ended (subject, where
appropriate, to normal year-end adjustments), in each case in accordance with
past practice and generally accepted accounting principles in the United States
("GAAP") consistently applied during the periods involved (except (i) as
otherwise disclosed in the notes thereto, (ii) in the case of unaudited interim
financial statements, such differences in presentation or omissions as are
permitted by Rule 10-01 of Regulation S-X promulgated by the SEC and (iii) the
unaudited interim financial statements do not contain all notes required by
GAAP). Since October 1, 1996, Parent has timely filed all material reports,
registration statements and other filings required to be filed by it with the
SEC under the rules and regulations of the SEC.
 
     3.5. No Undisclosed Liabilities. Neither Parent nor any of its Subsidiaries
has any liabilities or obligations of any nature, whether or not accrued,
contingent or otherwise, of a type required to be reflected on a balance sheet
prepared in accordance with GAAP, except (a) liabilities or obligations
reflected in the Parent SEC Reports filed after September 30, 1997 but prior to
the date hereof ("Parent Filed SEC Reports"), (b) liabilities and obligations
incurred under this Agreement and fees and expenses
                                       A-8
<PAGE>   157
 
related thereto, (c) liabilities and obligations incurred in the ordinary course
of business after June 30, 1998 and (d) liabilities or obligations which are not
reasonably expected, individually or in the aggregate, to have a Material
Adverse Effect on Parent.
 
     3.6. No Violation of Law. The businesses of Parent and its Subsidiaries are
not being conducted in violation of any law, ordinance or regulation of any
governmental body or authority (provided that no representation or warranty is
made in this Section 3.6 with respect to Environmental Laws (as defined in
Section 3.7)) except (a) as described in the Parent Filed SEC Reports and (b)
for violations or possible violations which would not, individually or in the
aggregate, have a Material Adverse Effect on Parent.
 
     3.7. Environmental Laws and Regulations. Except as described in the Parent
Filed SEC Reports, (a) Parent and each of its Subsidiaries is in compliance with
all applicable international, federal, state, local and foreign laws and
regulations relating to pollution or protection of human health or the
environment (including, without limitation, ambient air, surface water, ground
water, land surface or subsurface strata) (collectively, "Environmental Laws"),
which compliance includes, but is not limited to, the possession by Parent and
its Subsidiaries of all material permits and other governmental authorizations
required under applicable Environmental Laws, and compliance with the terms and
conditions thereof, except for noncompliance which would not, individually or in
the aggregate, have a Material Adverse Effect on Parent; (b) neither Parent nor
any of its Subsidiaries has received written notice of, or, to the knowledge of
Parent, is the subject of, any actions, causes of action, claims,
investigations, demands or notices by any Person asserting an obligation to
conduct investigations or clean-up activities under Environmental Law or
alleging liability under or noncompliance with any Environmental Law
(collectively, "Environmental Claims") which would, individually or in the
aggregate, have a Material Adverse Effect on Parent; and (c) to the knowledge of
Parent, there are no facts, circumstances or conditions in connection with the
operation of its business or any currently or formerly owned, leased or operated
facilities that are reasonably likely to lead to any such Environmental Claims
in the future, except for any such Environmental Claims which would not,
individually or in the aggregate, have a Material Adverse Effect on Parent.
 
     3.8. No Undisclosed Employee Benefit Plan Liabilities or Severance
Arrangements. Except as described in the Parent Filed SEC Reports, all "employee
benefit plans," as defined in Section 3(3) of the Employee Retirement Income
Security Act of 1974, as amended ("ERISA"), maintained or contributed to by
Parent or its Subsidiaries are in compliance with all applicable provisions of
ERISA and the Code, and Parent and its Subsidiaries do not have any liabilities
or obligations with respect to any such employee benefit plans, whether accrued,
contingent or otherwise, except (a) as described in the Parent Filed SEC
Reports, and (b) for instances of noncompliance or liabilities or obligations
that would not, individually or in the aggregate, have a Material Adverse Effect
on Parent. No employee of Parent will be entitled to any additional benefits or
any acceleration of the time of payment or vesting of any benefits under any
employee incentive or benefit plan, program or other arrangement as a result of
the transactions contemplated by this Agreement.
 
     3.9. Absence of Certain Changes or Events. Other than as disclosed in the
Parent Filed SEC Reports, since October 1, 1997 the businesses of Parent and its
Subsidiaries have been conducted in all material respects in the ordinary course
consistent with past practice, and there has not been any event, occurrence,
development or state of circumstances or facts that has had, or would have, a
Material Adverse Effect on Parent.
 
     3.10. Litigation. Except as described in the Parent Filed SEC Reports,
there are no actions, suits or proceedings pending (or, to Parent's knowledge,
threatened) against or affecting Parent or its Subsidiaries, or any of their
respective properties at law or in equity, or before any federal, state, local
or foreign governmental body or authority, which, individually or in the
aggregate, are reasonably likely to have a Material Adverse Effect on Parent. On
or before October 31, 1998, Parent will provide to the Company a complete list
of all pending or threatened actions, suits or proceedings involving amounts in
excess of $250,000.
 
                                       A-9
<PAGE>   158
 
     3.11. Lack of Ownership of Company Common Stock. Except for the Company
Option, neither Parent nor any of its Subsidiaries owns any shares of Company
Common Stock or other securities convertible into shares of Company Common
Stock.
 
     3.12. Tax Matters.
 
          (a) All federal, state, local and foreign Tax Returns (as defined in
     Section 3.12(d)) required to be filed by or on behalf of Parent, each of
     its Subsidiaries, and each affiliated, combined, consolidated or unitary
     group of which Parent or any of its Subsidiaries (i) is a member (a
     "Current Parent Group") or (ii) has been a member within six years prior to
     the date hereof but is not currently a member, but only insofar as any such
     Tax (as defined in Section 3.12(d)) relates to a taxable period ending on a
     date within the last six years (a "Past Parent Group", and together with
     Current Parent Groups, a "Parent Affiliated Group") have been timely filed,
     and all returns filed are complete and accurate except to the extent any
     failure to file or any inaccuracies in filed returns would not,
     individually or in the aggregate, have a Material Adverse Effect on Parent
     (it being understood that the representations made in this Section 3.12, to
     the extent that they relate to Past Parent Groups, or to any Subsidiary of
     Parent for periods prior to the time such Subsidiary was acquired by
     Parent, are made to the knowledge of Parent). All Tax Returns include any
     required disclosure of all positions taken therein that could give rise to
     a substantial underpayment penalty within Section 6662 of the Code or
     similar provision of state, local, foreign or other law. All Taxes due and
     owing by Parent, any Subsidiary of Parent or any Parent Affiliated Group
     have been paid, or adequately reserved for, except to the extent any
     failure to pay or reserve would not, individually or in the aggregate, have
     a Material Adverse Effect on Parent. There is no audit examination,
     deficiency, refund litigation, proposed adjustment or matter in controversy
     with respect to any Taxes due and owing by Parent, any Subsidiary of Parent
     or any Parent Affiliated Group which would, individually or in the
     aggregate, have a Material Adverse Effect on Parent. All assessments for
     Taxes due and owing by Parent, any Subsidiary of Parent or any Parent
     Affiliated Group with respect to completed and settled examinations or
     concluded litigation have been paid. As soon as practicable after the
     public announcement of the execution of this Agreement, Parent will provide
     the Company with written schedules of (i) the taxable years of Parent for
     which the statutes of limitations with respect to federal income Taxes have
     not expired, and (ii) with respect to federal income Taxes, those years for
     which examinations have been completed, those years for which examinations
     are presently being conducted, and those years for which examinations have
     not yet been initiated. Parent and each of its Subsidiaries have complied
     in all material respects with all rules and regulations relating to the
     withholding of Taxes, except to the extent any such failure to comply would
     not, individually or in the aggregate, have a Material Adverse Effect on
     Parent.
 
          (b) None of Parent nor any of its Subsidiaries knows of any fact or
     has taken any action that could reasonably be expected to prevent the
     Merger from constituting transactions described in Section 368(a) of the
     Code.
 
          (c) Any amount or other entitlement that could be received (whether in
     cash or property or the vesting of property) as a result of any of the
     transactions contemplated by this Agreement by any employee, officer or
     director of Parent or any of its affiliates who is a "disqualified
     individual" (as such term is defined in proposed Treasury Regulation
     Section 1.280G-1) under any employee benefit plan or other compensation
     arrangement currently in effect would not be characterized as an "excess
     parachute payment" or a "parachute payment" (as such terms are defined in
     Section 280G(b)(1) of the Code).
 
          (d) For purposes of this Agreement: (i) "Taxes" means any and all
     federal, state, local, foreign or other taxes of any kind (together with
     any and all interest, penalties, additions to tax and additional amounts
     imposed with respect thereto) imposed by any taxing authority, including,
     without limitation, taxes or other charges on or with respect to income,
     franchises, windfall or other profits, gross receipts, property, sales,
     use, capital stock, payroll, employment, social security, workers'
     compensation, unemployment compensation, or net worth, and taxes or other
     charges in the nature of
 
                                      A-10
<PAGE>   159
 
     excise, withholding, ad valorem or value added, and (ii) "Tax Return" means
     any return, report or similar statement (including the attached schedules)
     required to be filed with respect to any Tax, including, without
     limitation, any information return, claim for refund, amended return or
     declaration of estimated Tax.
 
     3.13. Required Vote. No vote of the stockholders of Parent is required by
law, the charter or by-laws of Parent or otherwise in order to consummate the
Merger and the transactions contemplated hereby.
 
     3.14. Insurance. The Parent Disclosure Schedule sets forth all material
policies of insurance or programs of self-insurance by which Parent or any of
its Subsidiaries or any of their respective properties or assets are covered
against present losses, all of which are now in full force and effect. Parent
agrees to maintain such policies (or policies of substantially the same nature)
in full force and effect at all times until the Effective Time. On or before
October 31, 1998, Parent will provide the Company a schedule which shall set
forth for the current policy year and each of the preceding five policy years
(i) a summary of the loss experience under each policy; (ii) a statement
describing each claim under an insurance policy which sets forth the name of the
claimant, a description of the policy, and the amount and a brief description of
the claim; and (iii) a statement describing the loss experience for all claims
that were self-insured, including the number and aggregate cost of such claims.
Neither Parent nor any of its Subsidiaries have received any refusal of coverage
or any notice that a defense will be afforded with reservation of rights.
 
     3.15. Intellectual Property. Parent and its Subsidiaries own or possess
adequate licenses or other valid rights to use all patents, patent rights,
trademarks, trademark rights and proprietary information used or held for use in
connection with their respective business as currently being conducted, except
where the failure to own or possess such licenses and other rights would not
have, individually or in the aggregate, a Material Adverse Effect on Parent, and
there are no assertions or claims challenging the validity of any of the
foregoing which are likely to have, individually or in the aggregate, a Material
Adverse Effect on Parent. The conduct of Parent's and its Subsidiaries'
businesses as currently conducted does not conflict with any patents, patent
rights, licenses, trademarks, trademark rights, trade names, trade name rights
or copyrights of others in any way likely to have, individually or in the
aggregate, a Material Adverse Effect on Parent. The systems, processes, and
computer software and hardware used, operated, sold or licensed by Parent or its
Subsidiaries that is material to its business or its internal operations is
capable of providing or is being or will be adapted, or is capable of being
replaced, to provide uninterrupted millennium functionality to record, store,
process and present calendar dates falling on or after January 1, 2000 in
substantially the same manner and with substantially the same functionality as
such systems, processes, software and hardware records, stores, processes and
presents such calendar dates falling on or before December 31, 1999, except as
would not have a Material Adverse Effect on Parent. The costs of the adaptations
and replacements referred to in the prior sentence will not have a Material
Adverse Effect on Parent.
 
     3.16. Material Contracts. The Parent Disclosure Schedule lists the
following contracts and other agreements to which Parent or any of its
Subsidiaries is a party (other than intercompany arrangements) as of the date
hereof (collectively, the "Parent Contracts"):
 
          (a) any agreement (or group of related agreements) for the lease of
     personal property to or from any person providing for lease payments in
     excess of $5,000,000 per annum and a term of more than one year;
 
          (b) any agreement (or group of related agreements) for the purchase or
     sale of raw materials, commodities, supplies, products, or other personal

     of $5,000,000.
 
          (c) any partnership or joint venture agreement;
 
          (d) any agreement (or group of related agreements) under which it has

     money, or any capitalized lease obligation, in
                                      A-11
<PAGE>   160

     interest or other encumbrance on any of its assets, tangible or intangible,
     to secure such indebtedness or obligations;
 
          (e) any agreement which purports to limit in any material respect the
     manner in which, or the localities in which, all or any material portion of
     the business of Parent and its Subsidiaries, taken as a whole, or the
     Company and its Subsidiaries, taken as a whole, is conducted;
 
          (f) any agreement with any of the stockholders of Parent and their
     affiliates relating to the voting, transfer or disposition of Parent's
     securities;
 
          (g) any profit sharing, stock option, stock purchase, stock
     appreciation, deferred compensation, severance or other material plan or
     arrangement (including any employee benefit plan) for the benefit of its
     current or former directors, officers and employees;
 
          (h) any collective bargaining agreement;
 
          (i) all turnkey and footage drilling contracts and all daywork
     drilling contracts for amounts in excess of $2,000,000 or that are not
     terminable or subject to completion within 90 days;
 
          (j) any agreement under which the consequences of a default or
     termination could have a Material Adverse Effect on Parent; or
 
          (k) any other agreement (or group of related agreements) the
     performance of which involves consideration in excess of $5,000,000 other
     than agreements entered into in the ordinary course.
 
Except as disclosed in the Parent Disclosure Schedule, there is no contract or
agreement that is material to the business, financial condition or results of
operations of Parent and its Subsidiaries, taken as a whole. Neither Parent nor
any of its Subsidiaries is in violation or default under (nor does there exist
any condition which upon the passage of time or the giving of notice would cause
a violation or default under) any Parent Contract, other than such violations or
defaults as would not have a Material Adverse Effect on Parent. To the knowledge
of Parent, none of the other parties to the Parent Contracts are in violation of
or in default under (nor does there exist any condition which upon the passage
of time or the giving of notice would cause a violation or default under) any
Parent Contract, other than such violations or defaults as would not have a
Material Adverse Effect on Parent.
 
     3.17. Ownership of Merger Sub; No Prior Activities. Merger Sub is a direct,
wholly owned subsidiary of Parent. Except for obligations or liabilities
incurred in connection with its incorporation or organization and the
transactions contemplated by this Agreement and except for this Agreement and
any other agreements or arrangements contemplated by this Agreement, Merger Sub
has not and will not have incurred, directly or indirectly, through any
Subsidiary or affiliate, any obligations or liabilities or engaged in any
business activities of any type or kind whatsoever or entered into any
agreements or arrangements with any person.
 
     3.18. Brokers. No broker, finder or investment banker is entitled to any
brokerage, finder's or other fee or commission in connection with the
transactions contemplated by this Agreement based upon arrangements made by or
on behalf of Parent or Merger Sub.
 
                                   ARTICLE IV
 
                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY
 
     Except as set forth on the Disclosure Schedule delivered by the Company to
Parent prior to the execution of this Agreement (the "Company Disclosure
Schedule" and together with the Parent Disclosure Schedule, the "Disclosure
Schedule"), the Company represents and warrants to Parent and Merger Sub that:
 
     4.1. Organization, Qualification, Etc. The Company is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Delaware and has the requisite corporate power and
 
                                      A-12
<PAGE>   161
 
authority to own its properties and assets and to carry on its business as it is
now being conducted and is duly qualified to do business and is in good standing
in each jurisdiction in which the ownership of its properties or the conduct of
its business requires such qualification, except for jurisdictions in which the
failure to be so qualified or in good standing would not, individually or in the
aggregate, have a Material Adverse Effect on the Company. The copies of the
Company's Restated Certificate of Incorporation, as amended, and Amended and
Restated Bylaws which have been delivered to Parent are complete and correct and
in full force and effect on the date hereof. Each of the Company's Significant
Subsidiaries is duly organized, validly existing and (if applicable) in good
standing under the laws of its jurisdiction of incorporation or organization,
has the power and authority to own its properties and to carry on its business
as it is now being conducted, and is duly qualified to do business and is (if
applicable) in good standing in each jurisdiction in which the ownership of its
property or the conduct of its business requires such qualification, except for
jurisdictions in which the failure to be so qualified or (if applicable) in good
standing would not, individually or in the aggregate, have a Material Adverse
Effect on the Company. All the outstanding shares of capital stock of, or other
ownership interests in, the Company's Significant Subsidiaries are validly
issued, fully paid and non-assessable and are owned by the Company, directly or
indirectly, free and clear of all liens, claims, charges or encumbrances, except
for restrictions contained in credit agreements and similar instruments to which
the Company is a party under which no event of default has occurred or arisen.
There are no existing options, rights of first refusal, preemptive rights, calls
or commitments of any character relating to the issued or unissued capital stock
or other securities of, or other ownership interests in, any Significant
Subsidiary of the Company.
 
     4.2. Capital Stock. The authorized capital stock of the Company consists of
100,000,000 shares of Company Common Stock, and 20,000,000 shares of preferred
stock, par value $.01 per share ("Company Preferred Stock"), of which 1,000,000
shares have been designated as Series A Junior Participating Preferred Stock

treasury. All the outstanding shares of Company Common Stock have been validly
issued and are fully paid and nonassessable. As of August 21, 1998, there were
no outstanding subscriptions, convertible or exchangeable securities, options,
warrants, or other rights, arrangements or commitments obligating the Company to
issue, deliver or sell any shares of its capital stock or debt securities, or
any securities of any kind convertible into its capital stock, or obligating the
Company to grant, extend or enter into any such subscription, option, warrant,
or other right, arrangement or commitment, other than: (a) rights ("Company
Rights") to acquire shares of the Company Series A Preferred Stock pursuant to
the Rights Agreement, dated as of August 21, 1998, between the Company and
Norwest Bank Minnesota, N.A. (the "Company Rights Plan"); (b) options and other
similar rights (the "Company Stock Options") to receive or acquire 1,296,600
shares of the Company Common Stock granted on or prior to August 21, 1998,

nonemployee director plans; and (c) warrants to purchase an aggregate of 397,000
shares of Company Common Stock (the "Company Warrants"). Except for the issuance

other rights referred to in clauses 4.2(a), (b) and (c), since August 21, 1998,
no shares of Company Common Stock or Company Preferred Stock have been issued
and no options, warrants or other securities convertible into shares of capital
stock of the Company have been issued or granted. Section 4.2 of the Company
Disclosure Schedule sets forth a true and complete list of all Company Stock
Options and Company Warrants, showing for each holder the number and type of
Company Stock Options and Company Warrants held, the exercise prices thereof,
and the dates of grant, expiration and vesting thereof. The Company has made
available to Parent complete and correct copies of all agreements evidencing the
Company Stock Options and Company Warrants. The Company has not granted any
registration rights with respect to its securities that are currently
exercisable.
 
     4.3. Corporate Authority Relative to this Agreement; No Violation. The
Company has the requisite corporate power and authority to execute and deliver
this Agreement and the Company Stock Option Agreement, and to consummate the
transactions contemplated hereby and thereby. The execution and delivery of this
Agreement and the Company Stock Option Agreement and the consummation of the
                                      A-13
<PAGE>   162
 
transactions contemplated hereby and thereby have been duly and validly
authorized by the Board of Directors of the Company and, except for the adoption
of this Agreement by its stockholders, no other corporate proceedings on the
part of the Company are necessary to authorize the consummation of the
transactions contemplated hereby and thereby. The Board of Directors of the
Company has taken all appropriate action so that none of the Company, Parent or
Merger Sub will be subject to the limitations on "business combinations" set
forth in Section 203 of Delaware Law by virtue of (a) the Company, Parent and
Merger Sub entering into this Agreement, (b) the Company and Parent entering
into the Company Stock Option Agreement, (c) Parent and the parties thereto
entering into the Stockholder Agreements and (d) the consummation by the parties
to the agreements referred to in clauses (a), (b) and (c) of the transactions
contemplated hereby and thereby. The Board of Directors of the Company has
determined that the transactions contemplated by this Agreement are advisable
and in the best interests of the Company and its stockholders and to recommend
to such stockholders that they adopt this Agreement. Neither the Company nor any
affiliate or associate of the Company has, at any time during the last three
years, owned in excess of 15% of the Parent Common Stock. This Agreement and the
Company Stock Option Agreement have been duly and validly executed and delivered
by the Company and, assuming this Agreement and the Company Stock Option
Agreement, as applicable, constitutes a valid and binding agreement of the other
parties hereto and thereto, this Agreement and the Company Stock Option
Agreement constitute valid and binding agreements of the Company, enforceable
against the Company in accordance with their terms (except insofar as
enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting creditors' rights
generally, or by principles governing the availability of equitable remedies).
The Company is not subject to or obligated under any charter, by-law or contract
provision or any license, franchise or permit, or subject to any order or
decree, which would be breached or violated by its executing or, subject to the
adoption of this Agreement by its stockholders, carrying out the transactions
contemplated by this Agreement and the Company Stock Option Agreement, except
for any breaches or violations which would not, individually or in the
aggregate, have a Material Adverse Effect on the Company. Other than in
connection with or in compliance with the provisions of Delaware Law, the
Securities Act, the Exchange Act, the HSR Act, Section 4043 of ERISA and the
securities or blue sky laws of the various states (collectively, the "Company
Required Approvals"), no authorization, consent or approval of, or filing with,
any governmental body or authority is necessary for the consummation by the
Company of the transactions contemplated by this Agreement, except for such
authorizations, consents, approvals or filings, the failure to obtain or make
which would not, individually or in the aggregate, have a Material Adverse
Effect on the Company or substantially impair or delay the consummation of the
transactions contemplated hereby.
 
     4.4. Reports and Financial Statements. The Company has previously furnished
to Parent true and complete copies of: (a) the Company's Annual Report on Form
10-K filed with the SEC for the year ended December 31, 1997; (b) the Company's

the SEC since November 1, 1997, except any final prospectus on Form S-8; and (e)
all Current Reports on Form 8-K filed by the Company with the SEC since January
1, 1998. As of their respective dates, such reports, proxy statements and
prospectuses (collectively, "Company SEC Reports") (i) complied as to form in
all material respects with the applicable requirements of the Securities Act,
the Exchange Act, and the rules and regulations promulgated thereunder and (ii)
did not contain any untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances under which they were made, not
misleading. Except to the extent that information contained in any Company SEC
Report has been revised or superseded by a later filed Company SEC Report, none
of Company SEC Reports contains any untrue statement of a material fact or omits
to state any material fact required to be stated therein or necessary in order
to make the statement therein, in light of the circumstances under which they
were made, not misleading. The audited consolidated financial statements and
unaudited consolidated interim financial statements included in the Company SEC
Reports (including any related notes and schedules) have been prepared in
accordance with and fairly present the financial position of the Company and its
consolidated Subsidiaries as of the
 
                                      A-14
<PAGE>   163
 
dates thereof and the results of their operations and their cash flows for the
periods or as of the dates then ended (subject, where appropriate, to normal
year-end adjustments), in each case in accordance with past practice and GAAP
consistently applied during the periods involved (except (i) as otherwise
disclosed in the notes thereto, (ii) in the case of unaudited interim financial
statements, such differences in presentation or omissions as are permitted by
Rule 10-01 of Regulation S-X promulgated by the SEC and (iii) the unaudited
interim financial statements do not contain all notes required by GAAP). Since
November 4, 1997, the Company has timely filed all material reports,
registration statements and other filings required to be filed by it with the
SEC under the rules and regulations of the SEC.
 
     4.5. No Undisclosed Liabilities. Neither the Company nor any of its
Subsidiaries has any liabilities or obligations of any nature, whether or not
accrued, contingent or otherwise, of a type required to be reflected on a
balance sheet prepared in accordance with GAAP, except (a) liabilities or
obligations reflected in Company SEC Reports filed after December 31, 1997 but
prior to the date hereof ("Company Filed SEC Reports"), (b) liabilities and
obligations incurred under this Agreement and fees and expenses related thereto,
(c) liabilities and obligations incurred in the ordinary course of business
after June 30, 1998 and (d) liabilities or obligations which are not reasonably
expected, individually or in the aggregate, to have a Material Adverse Effect on
the Company.
 
     4.6. No Violation of Law. The businesses of the Company and its
Subsidiaries are not being conducted in violation of any law, ordinance or
regulation of any governmental body or authority (provided that no
representation or warranty is made in this Section 4.6 with respect to
Environmental Laws) except (a) as described in the Company Filed SEC Reports and
(b) for violations or possible violations which would not, individually or in
the aggregate, have a Material Adverse Effect on the Company.
 
     4.7. Environmental Laws and Regulations. Except as described in the Company
Filed SEC Reports, (a) the Company and each of its Subsidiaries is in compliance
with all applicable Environmental Laws, which compliance includes, but is not
limited to, the possession by the Company and its Subsidiaries of all material
permits and other governmental authorizations required under applicable
Environmental Laws, and compliance with the terms and conditions thereof, except
for non-compliance which would not, individually or in the aggregate, have a
Material Adverse Effect on the Company; (b) neither the Company nor any of its
Subsidiaries has received written notice of, or, to the knowledge of the
Company, is the subject of, any Environmental Claims which would, individually
or in the aggregate, have a Material Adverse Effect on the Company; and (c) to
the knowledge of the Company, there are no facts, circumstances or conditions in
connection with the operation of its business or any currently or formerly
owned, leased or operated facilities that are reasonably likely to lead to any
such Environmental Claims in the future, except for any such Environmental
Claims which would not, individually or in the aggregate, have a Material
Adverse Effect on the Company.
 
     4.8. No Undisclosed Employee Benefit Plan Liabilities or Severance
Arrangements. Except as described in the Company Filed SEC Reports, all
"employee benefit plans," as defined in Section 3(3) of ERISA, maintained or
contributed to by the Company or its Subsidiaries are in compliance with all
applicable provisions of ERISA and the Code, and the Company and its
Subsidiaries do not have any liabilities or obligations with respect to any such
employee benefit plans, whether accrued, contingent or otherwise, except (a) as
described in the Company Filed SEC Reports and (b) for instances of non-
compliance or liabilities or obligations that would not, individually or in the
aggregate, have a Material Adverse Effect on the Company. No employee of the
Company will be entitled to any additional benefits or any acceleration of the
time of payment or vesting of any benefits under any employee incentive or
benefit plan, program or arrangement as a result of the transactions
contemplated by this Agreement.
 
     4.9. Absence of Certain Changes or Events. Other than as disclosed in the
Company Filed SEC Reports, since January 1, 1998 the businesses of the Company
and its Subsidiaries have been conducted in all material respects in the
ordinary course consistent with past practice, and there has not been any event,
occurrence, development or state of circumstances or facts that has had, or
would have, a Material Adverse Effect on the Company.
 
                                      A-15
<PAGE>   164
 
     4.10. Litigation. Except as described in the Company Filed SEC Reports or
previously disclosed in writing to Parent, there are no actions, suits or
proceedings pending (or, to the Company's knowledge, threatened) against or
affecting the Company or its Subsidiaries, or any of their respective properties
at law or in equity, or before any federal, state, local or foreign governmental
body or authority which, individually or in the aggregate, are reasonably likely
to have a Material Adverse Effect on the Company. On or before October 31, 1998,
the Company will provide to Parent a complete list of all pending or threatened
actions, suits or proceedings involving amounts in excess of $250,000.
 
     4.11. Company Rights Plan. Under the terms of the Company Rights Plan, as
amended prior to the execution of this Agreement, the execution and delivery of
this Agreement, the Company Stock Option Agreement and the Stockholder
Agreements, the performance of the transactions contemplated by this Agreement
or such other agreements in accordance with the terms hereof and thereof will
not (except to the extent caused by Parent's becoming the beneficial owner of
any Company Common Stock other than in accordance with this Agreement, the
Company Stock Option Agreement or the Stockholder Agreements) cause (i) Company
Rights to become exercisable under the Company Rights Plan or (ii) a
"Distribution Date", "Stock Acquisition Date", "Flip-In Trigger Date", "Flip-In
Event" or "Flip-Over Event" (as such terms are defined in the Company Rights
Plan) to occur upon the consummation of any such transactions. In addition, the
Company Rights Plan has been amended so that the Company Rights will expire
immediately prior to the Effective Time.
 
     4.12. Lack of Ownership of Parent Common Stock. Neither the Company nor any
of its Subsidiaries owns any shares of Parent Common Stock or other securities
convertible into shares of Parent Common Stock.
 
     4.13. Tax Matters.
 
          (a) All federal, state, local and foreign Tax Returns required to be
     filed by or on behalf of the Company, each of its Subsidiaries, and each
     affiliated, combined, consolidated or unitary group of which the Company or
     any of its Subsidiaries (i) is a member (a "Current Company Group") or (ii)
     has been a member within six years prior to the date hereof but is not
     currently a member, but only insofar as any such Tax relates to a taxable
     period ending on a date within the last six years (a "Past Company Group"
     and together with Current Company Groups, a "Company Affiliated Group") and
     Anadarko Drilling Company have been timely filed, and all returns filed are
     complete and accurate except to the extent any failure to file or any
     inaccuracies in filed returns would not, individually or in the aggregate,
     have a Material Adverse Effect on the Company (it being understood that the
     representations made in this Section 4.13, to the extent that they relate
     to Past Company Groups and Anadarko Drilling Company, or to any Subsidiary
     of the Company for periods prior to the time such Subsidiary was acquired
     by the Company, are made to the knowledge of the Company). All Tax Returns
     include any required disclosure of all positions taken therein that could
     give rise to a substantial underpayment penalty within Section 6662 of the
     Code or similar provision of state, local, foreign or other law. All Taxes
     due and owing by the Company, any Subsidiary of the Company or any Company
     Affiliated Group and Anadarko Drilling Company have been paid, or
     adequately reserved for, except to the extent any failure to pay or reserve
     would not, individually or in the aggregate, have a Material Adverse Effect
     on the Company. There is no audit examination, deficiency, refund
     litigation, proposed adjustment or matter in controversy with respect to
     any Taxes due and owing by the Company, any Subsidiary of the Company or
     any Company Affiliated Group which would, individually or in the aggregate,
     have a Material Adverse Effect on the Company. All assessments for Taxes
     due and owing by the Company, any Subsidiary of the Company or any Company
     consolidated group with respect to completed and settled examinations or
     concluded litigation have been paid. As soon as practicable after the
     public announcement of the execution of this Agreement, the Company will
     provide Parent with written schedules of (i) the taxable years of the
     Company for which the statutes of limitations with respect to federal
     income Taxes have not expired, and (ii) with respect to federal income
     Taxes, those years for which examinations have been completed, those years
     for which examinations are presently being conducted, and those years for
     which examinations have not yet been initiated. The Company and each of its
     Subsidiaries have
                                      A-16
<PAGE>   165
 
     complied in all material respects with all rules and regulations relating
     to the withholding of Taxes, except to the extent any such failure to
     comply would not, individually or in the aggregate, have a Material Adverse
     Effect on the Company. Neither the Company nor any Subsidiary is (nor has
     it ever been) a party to any tax sharing agreement and has not assumed the
     tax liability of any other person under a contract; has ever filed a
     consent under Section 341(f) of the Code; is required to make any
     adjustment under Section 481(a) of the Code for any tax year ending after
     the Effective Time by reason of a change in method of accounting or
     otherwise; or is required to make a payment with respect to the
     remuneration of an employee which would result in non-deductible expense
     pursuant to Section 162(m) of the Code. Neither the Company nor any
     Subsidiary is (nor has it ever been) a United States real property holding
     corporation within the meaning of Section 897(c)(2) of the Code during the
     applicable period specified in Section 897(c)(1)(A)(ii).
 
          (b) None of the Company nor any of its Subsidiaries knows of any fact
     or has taken any action that could reasonably be expected to prevent the
     Merger from constituting transactions described in Sections 368(a) of the
     Code.
 
          (c) Any amount or other entitlement that could be received (whether in
     cash or property or the vesting of property) as a result of any of the
     transactions contemplated by this Agreement by any employee, officer or
     director of the Company or any of its affiliates who is a "disqualified
     individual" (as such term is defined in proposed Treasury Regulation
     Section 1.280G-1) under any employee benefit plan or other compensation
     arrangement currently in effect would not be characterized as an "excess
     parachute payment" or a "parachute payment" (as such terms are defined in
     Section 280G(b)(1) of the Code).
 
     4.14. Required Vote. The affirmative vote of the holders of a majority of
the outstanding shares of the Company Common Stock (the "Company Stockholder
Approval") is required to adopt the Merger Agreement. No other vote of the
stockholders of the Company is required by law, the charter or by-laws of the
Company or otherwise in order for the Company to consummate the Merger and the
transactions contemplated hereby and by the Company Stock Option Agreement.
 
     4.15. Insurance. The Company Disclosure Schedule sets forth all material
policies of insurance or programs of self-insurance by which the Company or any
of its Subsidiaries or any of their respective properties or assets are covered
against present losses, all of which are now in full force and effect. The
Company agrees to maintain such policies (or policies of substantially the same
nature) in full force and effect at all times until the Effective Time. On or
before October 31, 1998, the Company will provide Parent a schedule which shall
set forth for the current policy year and each other policy year since November
1996 (i) a summary of the loss experience under each policy; (ii) a statement
describing each claim under an insurance policy; and (iii) a statement
describing the loss experience for all claims that were self-insured, including
the number and aggregate cost of such claims. Neither the Company nor any of its
Subsidiaries have received any refusal of coverage or any notice that a defense
will be afforded with reservation of rights.
 
     4.16. Intellectual Property. The Company and its Subsidiaries own or
possess adequate licenses or other valid rights to use all patents, patent
rights, trademarks, trademark rights and proprietary information used or held
for use in connection with their respective business as currently being
conducted, except where the failure to own or possess such licenses and other
rights would not have, individually or in the aggregate, a Material Adverse
Effect on the Company, and there are no assertions or claims challenging the
validity of any of the foregoing which are likely to have, individually or in
the aggregate, a Material Adverse Effect on the Company. The conduct of the
Company's and its Subsidiaries' businesses as currently conducted does not
conflict with any patents, patent rights, licenses, trademarks, trademark
rights, trade names, trade name rights or copyrights of others in any way likely
to have, individually or in the aggregate, a Material Adverse Effect on the
Company. The systems, processes, and computer software and hardware used,
operated, sold or licensed by the Company or its Subsidiaries that is material
to its business or its internal operations is capable of providing or is being
or will be adapted, or is capable of being replaced, to provide uninterrupted
millennium functionality to record, store, process and present
 
                                      A-17
<PAGE>   166
 
calendar dates falling on or after January 1, 2000 in substantially the same
manner and with substantially the same functionality as such systems, processes,
software and hardware records, stores, processes and presents such calendar
dates falling on or before December 31, 1999, except as would not have a
Material Adverse Effect on the Company. The costs of the adaptations and
replacements referred to in the prior sentence will not have a Material Adverse
Effect on the Company.
 
     4.17. Material Contracts. The Company Disclosure Schedule lists the
following contracts and other agreements to which the Company or any of its
Subsidiaries is a party (other than intercompany arrangements) as of the date
hereof (collectively, the "Company Contracts"):
 
          (a) any agreement (or group of related agreements) for the lease of
     personal property to or from any person providing for lease payments in
     excess of $500,000 per annum and a term of more than one year;
 
          (b) any agreement (or group of related agreements) for the purchase or
     sale of raw materials, commodities, supplies, products, or other personal
     property, or for the furnishing or receipt of services, the performance of
     which has a term more than six months, and involves consideration in excess
     of $500,000;
 
          (c) any partnership or joint venture agreement;
 
          (d) any agreement (or group of related agreements) under which it has
     created, incurred, assumed, or guaranteed any indebtedness for borrowed
     money, or any capitalized lease obligation, in excess of $500,000, or under
     which it has imposed a lien, security interest or other encumbrance on any
     of its assets, tangible or intangible, to secure such indebtedness or
     obligations;
 
          (e) any agreement which purports to limit in any material respect the
     manner in which, or the localities in which, all or any material portion of
     the business of the Company and its Subsidiaries, taken as a whole, or
     Parent and its Subsidiaries, taken as a whole, is conducted;
 
          (f) any agreement with any of the stockholders of the Company and
     their affiliates relating to the voting, transfer or disposition of the
     Company's securities;
 
          (g) any profit sharing, stock option, stock purchase, stock
     appreciation, deferred compensation, severance, or other material plan or
     arrangement (including any employee benefit plan) for the benefit of its
     current or former directors, officers, and employees;
 
          (h) any collective bargaining agreement;
 
          (i) all turnkey and footage drilling contracts and all daywork
     drilling contracts for amounts in excess of $2,000,000 or that are not
     terminable or subject to completion within 90 days;
 
          (j) any agreement under which the consequences of a default or
     termination could have a Material Adverse Effect on the Company; or
 
          (k) any other agreement (or group of related agreements) the
     performance of which involves consideration in excess of $500,000, other
     than agreements entered into in the ordinary course.
 
Except as disclosed in the Company Disclosure Schedule, there is no contract or
agreement that is material to the business, financial condition or results of
operations of the Company and its Subsidiaries, taken as a whole. Neither the
Company nor any of its Subsidiaries is in violation or default under (nor does
there exist any condition which upon the passage of time or the giving of notice
would cause a violation or default under) any Company Contract, other than such
violations or defaults as would not have a Material Adverse Effect on the
Company. To the knowledge of the Company, none of the other parties to the
Company Contracts are in violation of or in default under (nor does there exist
any condition which upon the passage of time or the giving of notice would cause
a violation or default under) any Company Contract, other than such violations
or defaults as would not have a Material Adverse Effect on the Company.

     4.18 Brokers. No broker, finder or investment banker is entitled to any
brokerage, finder's or other fee or commission in connection with the
transactions contemplated by this Agreement based upon arrangements made by or
on behalf of the Company.
 
     4.19 Opinion of Financial Advisor. The Company has received the opinion of
Donaldson, Lufkin & Jenrette Securities Corporation (a copy of which has been
delivered to Parent) to the effect that the consideration to be received in the
Merger is fair to the holders of Company Common Stock from a financial point of
view.

                                   COVENANTS
 
     5.1. Affirmative Covenants of the Company. The Company hereby covenants and
agrees that, prior to the Effective Time, unless otherwise expressly

     effect insurance and bonds comparable in amount and scope of coverage to
     that currently maintained; provided, however, that, in the event the

     proscribed by clauses 5.1(a) through (c), the Company shall consult with
     Parent and Parent shall consider in good faith the Company's request to
     take such actions and not unreasonably withhold its consent.
 
     5.2. Negative Covenants of the Company. Except as expressly contemplated by
this Agreement, as set forth in the Company Disclosure Schedule or otherwise
consented to in writing by Parent, from the date of this Agreement until the

     employee; or (iii) establish, adopt, enter into or amend any employee
     benefit plan or arrangement except as may be required by applicable law.

     acquisition directly from any wholly owned Subsidiary of the Company in
     exchange for capital contributions or loans to such Subsidiary), (ii)
     effect any recapitalization; or (iii) split, combine or reclassify any of
     its or its respective Subsidiaries' capital stock or issue or authorize or

     stock.

     shares held in treasury), any securities convertible into or exercisable or

     in accordance with their terms or issuances by any Subsidiary of the
     Company to the Company or any other Subsidiary of the Company); (ii) amend
     or otherwise modify the terms of any such rights, warrants or options the
     effect of which shall be to make such terms more favorable to the holders
     thereof (including, without limitation, declaring a "change of control" or

     otherwise acquire or agree to acquire any assets of any other person (other
     than the purchase of assets from suppliers or vendors in the ordinary
     course of business and consistent with past practice) which are material,
     individually or in the aggregate, to the Company and its Subsidiaries,
     taken as a whole.
 
          (f) other than (i) dispositions or proposed dispositions set forth on
     the Company Disclosure Schedule, (ii) as may be necessary or required by
     law to consummate the transactions contemplated hereby or (iii)
     dispositions in the ordinary course of business consistent with past

     dispose of, any of its material assets or any material assets of any of the
     Company's Significant Subsidiaries.
 
          (g) propose or adopt any amendments to its Restated Certificate of
     Incorporation, as amended, or, as to its Amended and Restated Bylaws, any

     expenditures in excess of $500,000 in the aggregate), except for (i)
     capital expenditures heretofore approved by the Company's Board of
     Directors and described in the Company Disclosure Schedule; and (ii)

     downs on the existing working capital line of credit, incur any obligation
     for borrowed money or purchase money indebtedness, whether or not evidenced
     by a note, bond, debenture or similar instrument, except in the ordinary
     course of business consistent with past practice.
 
          (j) take or agree to take any action that would or is reasonably

          (k) commit to do any of the foregoing;
 
provided, however, that, in the event the Company deems it necessary to take
certain actions that would otherwise be proscribed by this Section 5.2, the
Company shall consult with Parent and Parent shall consider in good faith the
Company's request to take such actions.
 
     5.3. Negative Covenants of Parent. Except as expressly contemplated by this
Agreement or otherwise consented to in writing by the Company, from the date of
this Agreement until the Effective Time, Parent will not, and will not permit
Merger Sub to, do any of the following:
 
          (a) amend any of the material terms or provisions of the Parent Common
     Stock.
 
          (b) knowingly take any action which would result in a failure to
     maintain the trading of Parent Common Stock on the American Stock Exchange.
 
          (c) declare or pay any dividends or other distribution (whether in
     cash, stock or other property) on outstanding shares of capital stock.
 
          (d) take or agree to take any action that would or is reasonably
     likely to result in any of Parent's or Merger Sub's representations and
     warranties set forth in this Agreement being untrue or in any of the
     conditions to the Merger not being satisfied.
 
          (e) commit to do any of the foregoing.
 
     5.4. Access and Information. Subject to confidentiality agreements to which
the Company or Parent or any of their respective Subsidiaries is a party, each
of the Company and Parent shall, and shall cause its Subsidiaries to, (a) afford
to the other party and its officers, directors, employees, accountants,
consultants, legal counsel, agents and other representatives (collectively, the
"Representatives") reasonable access at reasonable times upon reasonable prior
notice to its officers, employees, agents, properties, offices and other
facilities and its Subsidiaries and to the books and records thereof and (b)
furnish promptly to the other party and its Representatives such information
concerning its business, properties, contracts, records and personnel
(including, without limitation, financial, operating and other data and
information) as may be reasonably requested, from time to time, such other
party. Notwithstanding the foregoing, no party shall be required to provide any
information which it reasonably believes it may not provide to the other party
by reason of applicable law, rules or regulations, which constitutes information
protected by attorney/client privilege, or which it is required to keep
confidential by reason of contract or agreement with third parties. The parties
hereto will make reasonable and appropriate substitute disclosure arrangements
under circumstances in which the restrictions of the preceding sentence apply.
Each of Parent and the Company agrees that (i) it will, and will cause its
Representatives to, treat any information obtained hereunder in strict
accordance with Section 5.8 and (ii) it will not, and will cause its respective
Representatives not to, use any information obtained pursuant to this Section
5.4 for any purpose unrelated to the consummation of the transactions
contemplated by this Agreement.
 
     5.5. Registration Rights. Parent hereby covenants and agrees to grant
certain registration rights as described herein to each stockholder of the
Company who shall be subject to the resale restrictions of Rule 145 and Rule 144
of the Securities Act as a result of the transactions contemplated hereby
(individually, a "Rule 145 Stockholder," and collectively, the "Rule 145
Stockholders"). The grant of registration rights contemplated hereby shall be
evidenced by a written agreement between Parent and the Rule 145 stockholders,
in form and substance reasonably satisfactory to Parent and such stockholders,
to be entered into prior to the Effective Time. Such agreement shall, among
other things, provide the Rule 145 Stockholders collectively, the right to
demand a single registration under the Securities Act of not less than 1,000,000
shares of Parent Common Stock received by them in the Merger, commencing on the
90th day after the Effective Time and ending on the second anniversary date of
the Effective Time and upon receipt of any such demand Parent shall (a) as soon
as practicable use its best efforts to register shares of the Parent Common
Stock under the Securities Act which are the subject of the demand, (b) provide
an indemnity relating to such registration pursuant to which Parent agrees to
indemnify the Rule 145 stockholders for claims or causes of action arising from
information about Parent included in the
 
                                      A-21
<PAGE>   170
 
registration statement and (c) defray all costs and expenses of such
registration including the fees and expenses of one counsel to the selling
stockholders and all fees and expenses incurred by Parent but excluding
underwriting discounts or commissions applicable to shares sold by such
stockholders. The demand registration right shall be exercisable, at the option
of the selling stockholders, with regard to either an underwritten offering or a
shelf registration. In the event such stockholders elect a shelf registration,
Parent agrees to maintain the effectiveness of such registration for a minimum
of 180 days or until all shares covered thereby have been sold, whichever first
occurs.
 
     5.6 No Solicitation.
 
          (a) Except as expressly contemplated by this Agreement or otherwise
     consented to in writing by Parent, from the date of this Agreement until
     the earlier of the Effective Time or the date of termination of this
     Agreement in accordance with its terms, the Company will not directly or
     indirectly, and will not permit any of its Subsidiaries to, directly or
     indirectly, initiate, solicit or encourage (including by way of furnishing
     information or assistance), or take any other action to facilitate, any
     Company Acquisition Proposal (as defined below), or enter into discussions
     or negotiate with any person or entity in furtherance of such Company
     Acquisition Proposal, or enter into an agreement with respect to any
     Company Acquisition Transaction (as defined below) or agree to or endorse
     any Company Acquisition Proposal, or authorize or permit any of the
     officers, directors or employees of the Company or any of its Subsidiaries
     or any investment banker, financial advisor, attorney, accountant or other
     representative retained by the Company or any of its Subsidiaries to take
     any such action, and the Company shall notify Parent of all relevant terms
     of any Company Acquisition Proposal received by the Company or any of its
     Subsidiaries or by any such officer, director, investment banker, financial
     advisor or attorney within two business days after receipt thereof, and if
     such inquiry or proposal is in writing, the Company shall deliver or cause
     to be delivered to Parent a copy of such inquiry or proposal; provided,
     however, that nothing contained in this Agreement shall prohibit the Board
     of Directors of the Company from (i) complying with Rule 14e-2 promulgated
     under the Exchange Act with regard to a Company Acquisition Proposal; or
     (ii) at any time prior to the satisfaction of the condition set forth in
     Section 7.1(b), furnishing information to, or entering into discussions or
     negotiations with, any person or entity in connection with an unsolicited,
     bona fide, written Company Acquisition Proposal, recommending the same to
     the Company's stockholders or otherwise communicating with the Company's
     stockholders regarding such proposal in a manner permitted by law, if, and
     only to the extent that (A) the Board of Directors of the Company, after
     consultation with legal counsel (which may include its regularly engaged
     legal counsel), determines in good faith that such action is required for
     the Board of Directors of the Company to comply with its fiduciary duties
     to stockholders imposed by Delaware Law; (B) prior to furnishing such
     information to, or entering into discussions or negotiations with, such
     person or entity the Company (x) provides two business days' written notice
     to Parent to the effect that it is furnishing information to, or entering
     into discussions or negotiations with, such person or entity and (y)
     obtains from such person or entity a customary confidentiality agreement;
     and (C) the Company determines in good faith (after consultation with its
     financial advisor) that, in light of the information furnished to it
     relating to such Company Acquisition Proposal, the Company Acquisition
     Transaction contemplated thereby would, if consummated, result in a more
     favorable transaction than the transaction contemplated by this Agreement,
     taking into account the long-term prospects and interests of the Company
     and its stockholders. The Company will immediately cease and cause to be
     terminated any existing activities, discussions or negotiations with any
     parties heretofore conducted which are prohibited pursuant to this Section
     5.6(a). The Company agrees that it will take the necessary steps to
     promptly inform the individuals or entities referred to in the first
     sentence of this Section 5.6(a) of the obligations undertaken in this
     Section 5.6(a).
 
          (b) "Company Acquisition Proposal" means an inquiry or proposal which
     relates to or contemplates a Company Acquisition Transaction.

          (c) "Company Acquisition Transaction" means any of the following
     transactions:
 
             (i) any merger, consolidation, share exchange or other business
        combination involving the Company or any Subsidiary of the Company
        (other than any such arrangement between the Company and any of its
        Subsidiaries or among any of its Subsidiaries);
 
             (ii) any sale, exchange, transfer or other disposition (whether in
        the form of an asset sale, merger or otherwise) to any person (other
        than Parent or any of its Subsidiaries) of properties or assets of the
        Company or any of its Subsidiaries which constitute (A) all or
        substantially all of the properties and assets of the Company, (B) all
        or substantially all of the properties and assets of any Significant
        Subsidiary, or a material division or other business unit of the Company
        or any Significant Subsidiary, or (C) properties and assets which are
        material to the business or operations of the Company at its
        Subsidiaries, taken as a whole.
 
             (iii) any tender offer or exchange offer by any person (other than
        the Parent or any of its Subsidiaries) for 15% or more of the
        outstanding shares of Company Common Stock; or
 
             (iv) any acquisition of shares of Company Common Stock by any
        person or group (other than Parent or any of its Subsidiaries) which
        would require an amendment, waiver, termination or alteration of the
        Company Rights Plan so that such acquisition would not result in such
        person becoming an "Acquiring Person" under the terms of the Company
        Rights Plan.
 
     5.7.  Confidentiality. Between the date of this Agreement and the Effective
Time, the parties hereto will maintain in confidence, and will cause its
Representatives to maintain in confidence, and not use to the detriment of a
party to this Agreement any information obtained from a party to this Agreement
or its Subsidiaries in connection with this Agreement or the transactions
contemplated hereby (regardless of whether such information was obtained prior
to, on or after the date of this Agreement), unless (a) such information is
already known to such receiving party or to others not bound by a duty of
confidentiality or such information becomes publicly available through no fault
of such receiving party, (b) use of such information is necessary or appropriate
in making any filing or obtaining any consent or approval required for the
consummation of the transactions contemplated hereby or (c) the furnishing or
use of such information is required by legal proceedings or applicable law or
requirement of the American Stock Exchange. Upon any termination of this
Agreement, each party will return or destroy all confidential information
provided to it by the other party.

                             ADDITIONAL AGREEMENTS
 
     6.1.  Special Meeting of Company Stockholders. The Company shall promptly
after the date of this Agreement take all action necessary in accordance with
applicable law and its Restated Certificate of Incorporation, as amended, and
Amended and Restated Bylaws to convene a meeting of its stockholders to consider
and vote upon the approval of this Agreement and the Merger, and the Company
shall consult with Parent in connection therewith; provided that the Company
shall use its reasonable best efforts to hold the special meeting of
stockholders within 40 days after effectiveness of the Registration Statement.
The Company, through its Board of Directors, shall recommend approval of such
matters, subject to the terms and conditions set forth in Section 5.6.
 
     6.2.  Registration Statement; Proxy Statement.
 
          (a) Parent promptly shall prepare and shall file with the SEC and the
     American Stock Exchange a registration statement on Form S-4 under the
     Securities Act (the registration statement, together with the amendments
     thereto, being the "Registration Statement"), containing a proxy
     statement/prospectus, in connection with the registration of the Parent
     Common Stock to be issued in the Merger. The Company promptly shall prepare
     and file with the SEC a proxy statement that will be the same proxy
     statement/prospectus contained in the Registration Statement, and a form of
     proxy with respect to the meeting of the stockholders of the Company in
     connection with the Merger and
                                      A-23
<PAGE>   172
 
     the other transactions contemplated by this Agreement (such proxy
     statement/prospectus, together with any amendments thereof or supplements
     thereto, in each case in the form or forms mailed to such stockholders,
     being the "Proxy Statement"). Each of Parent and the Company shall use its
     best efforts to (i) cause the Registration Statement to become effective as
     promptly as practicable after such filing and (ii) cause the Proxy
     Statement to be mailed to stockholders of the Company at the earliest
     practicable date. Parent shall take any action required to be taken under
     any applicable federal or state securities laws in connection with the
     issuance of shares of Parent Common Stock in the Merger. Each of Parent and
     the Company shall furnish all information concerning it and the holders of
     its capital stock as the other may reasonably request in connection with
     such actions. As promptly as practicable after the Registration Statement
     shall have become effective, the Company shall mail the Proxy Statement to
     its stockholders. The Proxy Statement shall include the recommendation of
     the Board of Directors of the Company in favor of the Merger subject to the
     terms and conditions set forth in Section 5.6.
 
          (b) The information supplied by the Company for inclusion in the
     Registration Statement shall not, at the time the Registration Statement is
     declared effective, contain any untrue statement of a material fact or omit
     to state any material fact required to be stated therein or necessary in
     order to make the statements therein not misleading. The information
     supplied by the Company for inclusion in the Proxy Statement to be sent to
     the Company's stockholders in connection with the special meeting of
     stockholders to consider the Merger shall not, at the date the Proxy
     Statement (or any amendment thereof or supplement thereto) is first mailed
     to stockholders, at the time of the special stockholders' meeting or at the
     Effective Time, contain any untrue statement of a material fact or omit to
     state any material fact required to be stated therein or necessary in order
     to make the statements therein, in the light of the circumstances under
     which they are made, not misleading. If at any time prior to the Effective
     Time any event or circumstance relating to the Company or any of its
     affiliates, or its or their respective officers or directors, occurs or
     exists which should be set forth in an amendment to the Registration
     Statement or a supplement to the Proxy Statement, the Company shall
     promptly inform Parent and the Company shall cooperate with Parent in the
     prompt filing with the SEC of any necessary amendment or supplement to the
     Proxy Statement and the Registration Statement and, as required by law, in
     disseminating the information contained in such amendment or supplement to
     the stockholders of the Company. All documents that the Company is
     responsible for filing with the SEC in connection with the transactions
     contemplated herein will comply as to form and substance in all material
     respects with the applicable requirements of the Securities Act and the
     rules and regulations thereunder and the Exchange Act and the rules and
     regulations thereunder.
 
          (c) The information supplied by Parent for inclusion in the
     Registration Statement shall not, at the time the Registration Statement is
     declared effective, contain any untrue statement of a material fact or omit
     to state any material fact required to be stated therein or necessary in
     order to make the statements therein not misleading. The information
     supplied by Parent for inclusion in the Proxy Statement to be sent to the
     Company's stockholders in connection with the special stockholders' meeting
     shall not, at the date the Proxy Statement (or any amendment thereof or
     supplement thereto) is first mailed to stockholders, at the time of the
     meeting or at the Effective Time, contain any untrue statement of a
     material fact or omit to state any material fact required to be stated
     therein, in the light of the circumstances under which they are made, not
     misleading. If at any time prior to the Effective Time any event or
     circumstances relating to Parent or any of its respective affiliates, or to
     its or their respective officers or directors, occurs or exists which
     should be set forth in an amendment to the Registration Statement or a
     supplement to the Proxy Statement, Parent shall promptly inform the Company
     and Parent shall cooperate with the Company in the prompt filing with the
     SEC of any necessary amendment or supplement to the Proxy Statement and the
     Registration Statement and, as required by law, in disseminating the
     information contained in such amendment or supplement to the stockholders
     of the Company. All documents that Parent is responsible for filing with
     the SEC in connection with the transaction contemplated herein will comply
     as to form and substance in all material respects with the applicable
     requirements of the Securities Act and the rules and regulations thereunder
     and the Exchange Act and the rules and regulations thereunder.

          (d) (i) The Company shall use its reasonable efforts to cause to be
     delivered to Parent letters of PricewaterhouseCoopers LLP and, if
     applicable, Grant Thornton LLP dated as of a date within five business days
     before the date on which the Registration Statement shall become effective
     and addressed to Parent in form and substance reasonably satisfactory to
     Parent and customary in scope and substance for "comfort" letters delivered

     or otherwise to consummate and make effective the transactions contemplated
     by this Agreement; (ii) obtain the Parent Required Approvals and the
     Company Required Approvals; and (iii) make all necessary filings, and
     thereafter make any other required submissions, with respect to this
     Agreement and the Merger required under (A) the Securities Act (in the case
     of Parent) and the Exchange Act and the rules and regulations thereunder,
     and any other applicable federal or state securities laws, (B) the HSR Act
     and (C) any other applicable law; provided that Parent and the Company
     shall cooperate with each other in connection with the making of all such
     filings, including providing copies of all such documents to the non-filing
     party and its advisors prior to filing and, if requested, accepting all
     reasonable additions, deletions or changes suggested in connection
     therewith. The Company and Parent shall furnish all information required
     for any application or other filing to be made pursuant to the rules and
     regulations of any applicable law (including all information required to be
     included in the Proxy Statement and the Registration Statement) in
     connection with the transactions contemplated by this Agreement.
 
          (b) (i) Each of the Company and Parent shall give (or shall cause
     their respective Subsidiaries to give) any notices to third parties, and
     shall use, and cause their respective Subsidiaries to use, its reasonable
     best efforts to obtain any third party consents (A) necessary, proper or
     advisable to consummate the transactions contemplated in this Agreement,
     (B) disclosed or required to be disclosed in the Company Disclosure
     Schedule or the Parent Disclosure Schedule, (C) otherwise required under
     any contracts, licenses, leases or other agreements in connection with the
     consummation of the transactions contemplated herein or (D) required to

     the Effective Time or a Parent Material Adverse Effect from occurring after
     the Effective Time.
 
             (ii) In the event that either party shall fail to obtain any third
        party consent described in Section 6.3(b)(i), such party shall use its
        reasonable best efforts, and shall take any such actions reasonably
        requested by the other party hereto, to minimize any adverse effect upon
        the Company and Parent, their respective Subsidiaries, and their
        respective businesses resulting, or which could reasonably be expected
        to result after the Effective Time, from the failure to obtain such
        consent.
 
     6.4. Tax Treatment; Affiliates.
 
          (a) From and after the date hereof and until the Effective Time, none
     of Parent, the Company or any of their respective Subsidiaries shall
     knowingly (i) take any action, or fail to take any reasonable action, as a
     result of which the Merger would fail to qualify as a reorganization within
     the meaning of Section 368(a) of the Code or (ii) enter into any contract,
     agreement, commitment or arrangement to take or fail to take any such
     action. Each of the parties shall use its reasonable best efforts to obtain

                                      A-25
<PAGE>   174
 
          (b) Following the Effective Time, neither Parent nor any of its
     Subsidiaries shall knowingly take any action or knowingly cause any action
     to be taken which would cause the Merger to fail to qualify as a
     reorganization within the meaning of Section 368(a) of the Code (and any
     comparable provisions of applicable state or local law).
 
          (c) The Company shall use its best efforts to obtain from any person
     who may be deemed to have become an affiliate of the Company after the date

timing and content of the initial press release to be issued describing the
transactions contemplated by this Agreement, and will not make any public
announcement thereof prior to reaching such agreement unless required to do so
by applicable law or regulation. Thereafter, unless otherwise required by
applicable law or stock exchange requirements (and in that event, only if time
does not permit), Parent and the Company shall consult with each other before
issuing any press release or otherwise making any public statements with respect
to the Merger and shall not issue any such press release or make any such public
statement prior to such consultation.
 
     6.6. AMEX Listing. Parent shall use its best efforts to cause the shares of
Parent Common Stock to be issued in the Merger to be approved for listing on the
American Stock Exchange prior to the Effective Time.
 
     6.7. Indemnification of Directors and Officers.
 
          (a) The Restated Certificate of Incorporation and Bylaws of the
     Surviving Corporation shall contain the provisions with respect to
     indemnification set forth in the Restated Certificate of Incorporation, as
     amended, and Amended and Restated Bylaws of the Company on the date of this
     Agreement, which provisions shall not be amended, repealed or otherwise
     modified for a period of six years after the Effective Time in any manner
     that would adversely affect the rights thereunder of individuals who at any
     time prior to the Effective Time were directors or officers of the Company
     in respect of actions or omissions occurring at or prior to the Effective
     Time (including, without limitation, the transactions contemplated by this
     Agreement), unless such modification is required by Law.
 
          (b) From and after the Effective Time, the Surviving Corporation and
     Parent (each, an "Indemnifying Party") shall jointly and severally
     indemnify, defend and hold harmless the present and former officers and
     directors of the Company or any of its Subsidiaries (collectively, the
     "Indemnified Parties") against all losses, expenses, claims, damages,
     liabilities or amounts that are paid in settlement of (with the approval of
     Parent and the Surviving Corporation (which approval shall not unreasonably
     be withheld or delayed)), or otherwise in connection with, any threatened
     or actual claim, action, suit, proceeding or investigation (a "Claim"),
     based in whole or in part on the fact that such person is or was a director
     or officer of the Company or any of its Subsidiaries and arising out of
     actions or omissions occurring at or prior to the Effective Time
     (including, without limitation, the transactions contemplated by this
     Agreement), in each case to the full extent permitted under Delaware Law
     (and shall pay expenses (including fees and disbursements of counsel), as
     incurred, in advance of the final disposition of any such action or
     proceeding to each Indemnified Party to the fullest extent permitted under
     Delaware Law, upon receipt from the Indemnified Party to whom expenses are
     advanced of the undertaking to repay such advances contemplated by Delaware
     Law).
 
          (c) Without limiting the foregoing, in the event any Claim is brought
     against any Indemnified Party (whether arising before or after the
     Effective Time) after the Effective Time (i) the Indemnified Parties may
     retain the Company's regularly engaged independent legal counsel, or other
     independent legal counsel satisfactory to them provided that such other
     counsel shall be reasonably
                                      A-26
<PAGE>   175
 
     acceptable to the Surviving Corporation, (ii) the Indemnifying Parties
     shall jointly and severally pay all reasonable fees and expenses of such
     counsel for the Indemnified Parties promptly as statements therefor are
     received and (iii) the Indemnifying Parties will use their reasonable best
     efforts to assist in the vigorous defense of any such matter, provided that
     no Indemnifying Party shall be liable for any settlement of any Claim
     effected without its written consent, which consent shall not be
     unreasonably withheld or delayed. Any Indemnified Parties wishing to claim
     indemnification under this Section 6.7, upon learning of any such Claim,
     shall notify the Indemnifying Parties (although the failure so to notify
     the Indemnifying Parties shall not relieve the Indemnifying Parties from
     any liability which the Indemnifying Parties may have under this Section
     6.7 except to the extent such failure prejudices the Indemnifying Parties),
     and shall, if requested, deliver to the Indemnifying Parties the
     undertaking contemplated by Delaware Law. The Indemnified Parties as a
     group may retain one law firm (in addition to local counsel) to represent
     them with respect to each such matter unless there is, under applicable
     standards of professional conduct (as determined by counsel to the
     Indemnified Parties), a conflict on any significant issue between the
     positions of any two or more Indemnified Parties, in which event, such
     additional counsel as may be required may be retained by the Indemnified
     Parties.
 
          (d) Commencing at the Effective Time, the directors and officers of
     Surviving Corporation shall be insured under the policies of directors and
     officers insurance currently or hereafter maintained by Parent. In
     addition, for a period of four years after the Effective Time, Parent shall
     cause to be maintained in effect the current policies of directors' and
     officers' liability insurance maintained by the Company and its
     Subsidiaries (provided that Parent may substitute therefor policies of at
     least the same coverage and amounts containing terms that are no less
     advantageous in any material respect to the persons covered thereby) with
     respect to claims arising from facts or events which occurred before the
     Effective Time; provided that Parent shall not be required to pay an annual
     premium for such insurance in excess of two times the last annual premium
     paid by the Company prior to the date hereof, but in such case shall
     purchase as much coverage as possible for such amount.
 
          (e) This Section 6.7 is intended to be for the benefit of, and shall
     be enforceable by, the Indemnified Parties, their heirs and personal
     representatives and shall be binding on Parent, Merger Sub and the
     Surviving Corporation and their representative successors and assigns. No
     termination or modification of the obligations of the Indemnifying Parties
     under this Section 6.7 that adversely affects the rights of any Indemnified
     Party shall be effective against such Indemnified Party without his or her
     prior written consent.
 
          (f) The rights granted to the Indemnified Parties hereunder shall be
     in addition to, and not in limitation of, any other rights that the
     Indemnified Parties may have by contract, Delaware Law, or otherwise.
 
          (g) In the event Parent, the Surviving Corporation or any of their
     respective successors or assigns (i) consolidates with or merges into any
     other person and shall not be the continuing or surviving corporation or
     entity in such consolidation or merger or (ii) transfers all or
     substantially all of its properties and assets to any person, then and in
     either such case, proper provision shall be made so that the successors and
     assigns of Parent or the Surviving Corporation, as the case may be, shall
     assume the obligations set forth in this Section 6.7.
 
     6.8. Agreement to Defend. In the event any claim, action, suit,
investigation or other proceeding by any governmental body or other person or
other legal or administrative proceeding is commenced that questions the
validity or legality of the transactions contemplated hereby or seeks damages in
connection therewith, whether before or after the Effective Time, the parties
hereto agree to cooperate and use their reasonable efforts to defend against and
respond thereto.
 
     6.9. Obligations of Merger Sub. Parent shall take all action necessary to
cause Merger Sub to approve and adopt the Agreement, to perform its obligations
hereunder and to consummate the Merger on the terms and conditions set forth in
this Agreement.

purchase method.
 
     6.11. Executive Employment Agreement. As of or prior to the Effective Time,
Parent shall cause Nabors Drilling USA, Inc. to enter into a new employment
agreement with James E. Brown, the Chairman and Chief Executive Officer of the
Company, in substantially the form of Exhibit 6.11A.
 
     6.12. Takeover Statutes. If any "fair price", "moratorium", "control share
acquisition" or other form of antitakeover statute or regulation shall become
applicable to the transactions contemplated hereby, each of Parent and the
Company and the members of their respective Boards of Directors shall grant such
approvals and take such actions as are reasonably necessary so that the
transactions contemplated hereby may be consummated as promptly as practicable
on the terms contemplated hereby and otherwise act to eliminate or minimize the
effects of such statute or regulation on the transactions contemplated hereby.
 
     6.13. Employee Matters. The Surviving Corporation shall be responsible for
all severance obligations payable to its employees terminated after the
Effective Time, in accordance with its severance policies, if any, as in effect
at the time of such termination. Notwithstanding the foregoing, in the event an
employee of the Company listed in Exhibit 6.13 and still employed by the Company
immediately prior to the Effective Time is terminated by the Surviving
Corporation (or an affiliate) within one year of the Effective Time, Parent
shall cause the Surviving Corporation (or such affiliate) to pay such terminated
employee the amounts specified opposite such employee's name on Exhibit 6.13, in
lieu of any severance otherwise payable by the Surviving Corporation (or such
affiliate) under any severance agreement, policy or program in effect at the
time of such termination.
 
     6.14. Stockholder Agreements.
 
          (a) From and after the date of this Agreement and ending on the date
     of termination of this Agreement, the Company agrees not to register the
     transfer (book-entry or otherwise) of any certificate or uncertificated
     interest representing any of the shares beneficially owned by the
     stockholders signatory to the Stockholder Agreements (excluding shares with
     respect to which such stockholder does not possess sole power to dispose or
     direct the disposition) unless such transfer is permitted under the terms
     of the applicable Stockholders Agreement.
 
          (b) The Company represents to Parent and Merger Sub that, except as
     disclosed in Schedule 4.5, paragraph 2 of the Company Disclosure Schedule,
     none of the execution and delivery of the Stockholder Agreements by the
     parties thereto, the consummation of the transactions contemplated thereby
     or compliance by the stockholders signatory thereto with any of the
     provisions thereof will trigger a "change in control" or similar provision
     of any contract, agreement or understanding to which the Company or any of
     Company's Subsidiaries is a party, or by which any of their respective
     properties or assets are bound.

          (c) No Order. No governmental entity or federal or state court of
     competent jurisdiction shall have enacted, issued, promulgated, enforced or
     entered any statute, rule, regulation, executive order, decree, injunction
     or other order (whether temporary, preliminary or permanent) which is in
     effect and which has the effect of making the Merger illegal or otherwise
     prohibiting consummation of the Merger.
 
          (d) Tax Opinion. The Company shall have received an opinion of Baker &
     Botts, L.L.P., and Parent shall have received an opinion of Baker &
     McKenzie, each dated the Effective Time, subject to the assumptions and
     conditions set forth therein, to the effect that (i) the Merger will be
     treated for federal income tax purposes as a reorganization within the
     meaning of Section 368(a) of the Code; (ii) each of Parent, Merger Sub and
     the Company will be a party to reorganization within the meaning of Section

     Company as a result of the Merger will be recognized to the extent of the
     amount of cash received by such stockholder and income or gain may be
     recognized by stockholders in special circumstances (such as a stockholder
     who acquired Company Common Stock through exercise of employee stock
     options or otherwise as compensation for employment). In rendering such
     opinions, Baker & Botts, L.L.P. and Baker & McKenzie may receive and rely
     upon representations contained in certificates of the Company, Parent,
     Merger Sub and others.
 
          (e) HSR Act. The applicable waiting period under the HSR Act shall

     warranties of the Company contained in this Agreement shall be true and

     representations and warranties which address matters only as of a
     particular date shall remain true and correct as of such date, except where
     the failure to be so true and correct would not have a Material Adverse
     Effect on the Company. Solely for purposes of this Section 7.2(a) and in
     determining compliance with the condition(s) set forth herein, any
     representation and warranty made by the Company in this Agreement shall be
     read and interpreted as if the qualification stated therein with respect to
     materiality or the Material Adverse Effect on the Company were not
     contained therein. Parent shall have received a certificate of the
     President of the Company to such effect.
 
          (b) Agreements and Covenants. The Company shall have performed or
     complied in all material respects with all agreements and covenants
     required by this Agreement to be performed or complied with by it on or

the Company to effect the Merger and the other transactions contemplated in this
Agreement, unless otherwise waived in writing, is also subject to the following
conditions:
 
          (a) Representations and Warranties. Each of the representations and
     warranties of Parent and Merger Sub contained in this Agreement shall be
     true and correct when made and on and as of the Effective Time as if made
     on and as of such date, except where the failure to be so true and correct
     would not have a Material Adverse Effect on Parent, and except that those
     representations and warranties which address matters only as of a
     particular date shall remain true and correct as of such date, except where
     the failure to be so true and correct would not have a Material Adverse
     Effect on Parent. Solely for purposes of this Section 7.3(a) and in
     determining compliance with the condition(s) set forth herein, any
     representation and warranty made by the Parent in this Agreement shall be
     read and interpreted as if the qualification stated therein with respect to

     Parent to such effect.

                       TERMINATION, AMENDMENT AND WAIVER
 
     8.1. Termination.
 
          (a) This Agreement may be terminated at any time prior to the
     Effective Time, whether before or after approval of this Agreement and the
     Merger by the stockholders of the Company, only in the following ways:
 
             (i) by mutual written consent of Parent and the Company;
 
             (ii) by Parent, upon an intentional breach of any covenant or
        agreement on the part of the Company set forth in this Agreement, or if
        any material representation or warranty of the Company shall be or shall
        have become untrue, in either case such that the conditions set forth in
        Section 7.2(a) or Section 7.2(b) would not be satisfied (a "Terminating
        Company Breach"), provided that if such Terminating Company Breach is
        curable by the Company through the exercise of its reasonable best
        efforts and for so long as the Company continues to exercise such
        reasonable best efforts, Parent may not terminate this Agreement under
        this Section 8.1(a)(ii);
 
             (iii) by the Company, upon an intentional breach of any covenant or
        agreement on the part of Parent or Merger Sub set forth in this
        Agreement, or if any material representation or warranty of Parent or
        Merger Sub shall be or shall have become untrue, in either case such
        that the conditions set forth in Section 7.3(a) or Section 7.3(b) would
        not be satisfied (a "Terminating Parent Breach"), provided that if such
        Terminating Parent Breach is curable by Parent or Merger Sub through the
        exercise of its reasonable best efforts and for so long as Parent or
        Merger Sub continues to exercise such reasonable best efforts, the
        Company may not terminate this Agreement under this Section 8.1(a)(iii);
 
             (iv) by either Parent or the Company, if there shall be any order,
        decree or ruling of any United States federal or state court of
        competent jurisdiction, or any United States federal or state
        governmental, regulatory or administrative authority, which is final and
        nonappealable, restraining, enjoining or otherwise preventing the
        consummation of the Merger;
 
                                      A-30
<PAGE>   179
 
             (v) by either Parent or the Company, if the Merger shall not have
        been consummated before September 30, 1999 (unless the failure to
        consummate the Merger by such date shall be due to the action or failure
        to act of the party seeking to terminate this Agreement);
 
             (vi) by either Parent or the Company, if the stockholders' meeting
        provided for in Section 6.1 shall have been held and the Agreement shall
        fail to receive the stockholder approval required by Section 7.1(b) at
        such meeting (including any adjournments and postponements thereof);
 
             (vii) by Parent, if, (A) the Board of Directors of the Company
        withdraws, or materially modifies or materially changes, its
        recommendation of this Agreement or the Merger in a manner adverse to
        Parent or Merger Sub or shall have resolved to do any of the foregoing;
        (B) the Board of Directors of the Company (i) shall have recommended to
        the stockholders of the Company a Company Acquisition Proposal or (ii)
        after the expiration of ten business days following the public
        announcement (or, in the case of a tender offer, following the
        commencement of such tender offer) of any Company Acquisition Proposal,
        shall have (1) failed to recommend against accepting such Company
        Acquisition Proposal or (2) taken no position with respect thereto or
        (iii) resolved to do any of the foregoing; or (C) the Company shall have
        effected an amendment, waiver, termination or other alteration of the
        provisions of the Company Rights Plan in such a manner that any person
        (other than Parent or Merger Sub) shall have been permitted to acquire
        "beneficial ownership" or the right to acquire beneficial ownership of,
        or any "group" (as such terms are defined under Section 13(d) of the
        Exchange Act and the rules and regulations promulgated thereunder),
        shall have been formed which beneficially owns, or has the right to
        acquire beneficial ownership of, more than 15% of the then outstanding
        shares of capital stock of the Company, in each case without triggering
        the Company Rights Plan; or
 
             (viii) by the Company, if the Board of Directors of the Company
        determines that proceeding with the Merger would be inconsistent with
        its fiduciary obligations by reason of a Company Acquisition Proposal as
        to which the Company has made the determinations and taken the actions
        described in clauses (A), (B) and (C) of the proviso contained in
        Section 5.6(a), and elects to terminate this Agreement effective prior
        to the satisfaction of the condition set forth in Section 7.1(b);
        provided that the Company may not effect such termination pursuant to
        this Section 8.1(a)(viii) unless and until (A) Parent receives at least
        five business days' prior written notice from the Company of its
        intention to effect such termination pursuant to this Section
        8.1(a)(viii); (B) during such period, the Company shall, and shall cause
        its respective financial and legal advisors to, consider any adjustment
        in the terms and conditions of this Agreement that Parent may propose;
        and provided, further, that any termination of this Agreement pursuant
        to this Section 8.1(a)(viii) shall not be effective until the Company
        has made the termination payment required by Section 8.5(b).
 
          (b) Notwithstanding any of the foregoing, the right of any party
     hereto to terminate this Agreement pursuant to Section 8.1(a) shall remain
     operative and in full force and effect regardless of any investigation made
     by or on behalf of any party hereto, any person controlling any such party
     or any of their respective officers or directors, whether prior to or after
     the execution of this Agreement.
 
     8.2. Effect of Termination. Except as provided in Section 8.5 or Section
9.1, in the event of the termination of this Agreement pursuant to Section
8.1(a), this Agreement shall forthwith become void, there shall be no liability
on the part of Parent, Merger Sub or the Company or any of their respective
officers or directors to the other and all rights and obligations of any party
hereto shall cease, except that nothing herein shall relieve any party for any
breach of this Agreement.
 
     8.3. Amendment. This Agreement may be amended by the parties hereto by
action taken by or on behalf of their respective Boards of Directors at any time
prior to the Effective Time; provided, however, that, after approval of the
Merger by the stockholders of the Company, no amendment shall be made which by
Delaware Law requires the further approval of stockholders. This Agreement may
not be amended except by an instrument in writing signed by the parties hereto.
                                      A-31

     8.4. Waiver. At any time prior to the Effective Time, any party hereto may
(a) extend the time for the performance of any of the obligations or other acts
of the other parties hereto, (b) waive any inaccuracies in the representations
and warranties of the other party contained herein or in any document delivered
pursuant hereto and (c) waive compliance by the other parties with any of the
agreements or conditions contained herein. Any such extension or waiver shall be
valid only if set forth in an instrument in writing signed by the party or
parties to be bound thereby.
 
     8.5. Fees; Expenses and Other Payments.
 
          (a) Except as provided in Section 8.5(b) and Section 8.5(c), each
     party shall bear its own costs and expenses in connection with this
     Agreement and the transactions contemplated hereby provided, however, that
     the allocable share of each of Parent and the Company for all costs and
     expenses related to printing, filing and mailing the Registration Statement
     and the Proxy Statement and all SEC and other regulatory filing fees
     incurred in connection with the Registration Statement and the Proxy
     Statement shall be one-half. Notwithstanding anything to the contrary, all
     of the costs and expenses in connection with this Agreement and the
     transactions contemplated hereby incurred by the Company and the Parent
     shall, upon the consummation of the Merger, be borne by the Surviving
     Corporation.
 
          (b) If this Agreement is terminated for any reason pursuant to Section
     8.1(a)(vi), (vii) or (viii), then the Company shall pay Parent a fee of $5
     million, plus all reasonable third party costs incurred by Parent
     (including, but not limited to costs for attorneys, accountants and other
     advisors) prior to the time of such termination in cash by wire transfer to
     an account designated by Parent; provided that such third party costs shall
     not exceed $500,000.
 
          (c) If this Agreement is terminated by either the Parent or the
     Company pursuant to Section 8.1(a)(ii) or (iii) (as the case may be), then
     the other party shall pay the party that terminated the Agreement a fee of
     $7.5 million (in the case of a termination by Parent pursuant to Section
     8.1(a)(ii)) or a fee of $15.0 million (in the case of a termination by the
     Company pursuant to Section 8.1(a)(iii)).
 
          (d) The parties agree that the amounts provided in Section 8.5(b) and
     (c) payable upon the occurrence of the events specified therein have been
     determined by negotiation and reflect their best estimate and judgment of
     the monetary value of the losses and damages to be incurred in connection
     with, and time, effort, expense and cost of opportunity associated with,
     the transactions contemplated in this Agreement, and the parties agree to
     accept payment of such amount as liquidated damages in full and complete
     satisfaction of all claims and expenses arising from the occurrence of such
     events (including, but not limited to, claims for specific performance).
     Any payment required to be made pursuant to Section 8.5(b) or (c) shall be
     made not later than two business days after delivery to the party required
     to make such payment of notice of demand for payment and shall be made by
     wire transfer of immediately available funds to an account designated in
     such notice. Nothing in this Section 8.5(d) shall affect the rights of
     either party under the Company Stock Option Agreement.

         Opinion of Donaldson, Lufkin & Jenrette Securities Corporation
 
                               February 12, 1999
 
Board of Directors
Bayard Drilling Technologies, Inc.
4005 NW Expressway, Suite 550
Oklahoma City, OK 73116
 
Dear Sirs:
 
     You have requested our opinion as to the fairness, from a financial point
of view, to the holders of common stock, par value $0.01 per share ("Company
Common Stock"), of Bayard Drilling Technologies, Inc. (the "Company") of the
Consideration (as defined below) to be received pursuant to the terms of the
Agreement and Plan of the Merger (the "Merger Agreement"), dated as of October
19, 1998 and as amended, by and among Nabors Industries, Inc. ("Nabors"), Nabors
Acquisition Corp. VII ("Merger Sub"), a wholly owned subsidiary of Nabors, and
the Company, pursuant to which Nabors Acquisition Corp. VII will be merged (the
"Merger") with and into the Company.
 
     Pursuant to the Merger Agreement, each share of Company Common Stock will
be converted, subject to certain exceptions, into the right to receive (i)
0.3375 shares of common stock, $0.10 par value per share ("Nabors Common
Stock"), of Nabors and (ii) $0.30 in cash (collectively, the "Consideration").
 
     In arriving at our opinion, we have reviewed the Merger Agreement, Stock
Option Agreement dated October 19, 1998 (the "Stock Option Agreement") by and
among Nabors and the Company, and the Stockholder Agreements dated October 19,
1998 (the "Stockholder Agreements") between Nabors, Merger Sub and certain
stockholders (the Stockholder Agreements, together with the Stock Option
Agreement and the Merger Agreement, the "Agreements"). We also have reviewed
financial and other information that was publicly available or furnished to us
by the Company and Nabors, including information provided during discussions
with their respective managements. Included in the information provided during
discussions with the respective managements were certain financial projections
of the Company for the period beginning January 1, 1998 and ending December 31,
2002 prepared by the management of the Company. In addition, we have compared
certain financial and securities data of the Company and Nabors with various
other companies whose securities are traded in public markets, reviewed the
historical stock prices and trading volumes of Company Common Stock and Nabors
Common Stock, reviewed prices and premiums paid in certain other business
combinations and conducted such other financial studies, analyses and
investigations as we deemed appropriate for purposes of this opinion. We were
not requested to, nor did we, solicit the interest of any other party in
acquiring the Company.
 
     In rendering our opinion, we have relied upon and assumed the accuracy and
completeness of all of the financial and other information that was available to
us from public sources, that was provided to us by the Company and Nabors or
their respective representatives, or that was otherwise reviewed by us. In
particular, we have relied upon the estimates of management of the Company of
the operating synergies achievable as a result of the Merger and upon our
discussion of such synergies with the management of Nabors. With respect to the
financial projections supplied to us, we have assumed that they have been
reasonably prepared on the basis reflecting the best currently available
estimates and judgments of the management of the Company as to the future
operating and financial performance of the Company. We have not assumed any
responsibility for making an independent evaluation of any assets or liabilities
or for making any independent verification of any of the information reviewed by
us. We have relied as to certain legal matters on advice of counsel to the
Company.
<PAGE>   185
 
     Our opinion is necessarily based on economic, market, financial and other
conditions as they exist on, and on the information made available to us as of,
the date of this letter. It should be understood that, although subsequent
developments may affect this opinion, we do not have any obligation to update,
revise or reaffirm this opinion. We are expressing no opinion as to the prices
at which Nabors Common Stock will actually trade at any time. Our opinion does
not address (i) the relative merits of the Merger and the other business
strategies being considered by the Company's Board of Directors, (ii) the
business decision of the Company's Board of Directors to proceed with the Merger
or (iii) the fairness of any terms of the Agreements, other than the
Consideration to be received by the holders of the Company Common Stock in the
Merger. Our opinion does not constitute a recommendation to any stockholder as
to how such stockholder should vote on the proposed transaction.
 
     Donaldson, Lufkin & Jenrette Securities Corporation ("DLJ"), as part of its
investment banking services, is regularly engaged in the valuation of businesses
and securities in connection with mergers, acquisitions, underwritings, sales
and distributions of listed and unlisted securities, private placements and
valuations for corporate and other purposes. DLJ acted as lead managing
underwriter for the initial public offering of the Company Common Stock in
November 1997. DLJ and the Company are currently involved in class action
litigation relating to such offering. In addition, DLJ acted as lead managing
underwriter for the issuance of the Company's 11% Senior Notes in June 1998 and
has advised the Company with respect to its adoption of the shareholders rights
plan in August 1998.
 
     Based upon the foregoing and such other factors as we deem relevant, we are
of the opinion that the Consideration to be received in the Merger is fair to
the holders of Company Common Stock from a financial point of view.
 
                                            Very truly yours,

              SECTION 262 OF THE DELAWARE GENERAL CORPORATION LAW
 
     Appraisal Rights. (a) Any stockholder of a corporation of this State who
holds shares of stock on the date of the making of a demand pursuant to
subsection (d) of this section with respect to such shares, who continuously
holds such shares through the effective date of the merger or consolidation, who
has otherwise complied with subsection (d) of this section and who has neither
voted in favor of the merger or consolidation nor consented thereto in writing
pursuant to sec.228 of this title shall be entitled to an appraisal by the Court
of Chancery of the fair value of the stockholder's shares of stock under the
circumstances described in subsections (b) and (c) of this section. As used in
this section, the word "stockholder" means a holder of record of stock in a
stock corporation and also a member of record of a nonstock corporation; the
words "stock" and "share" mean and include what is ordinarily meant by those
words and also membership or membership interest of a member of a nonstock
corporation; and the words "depository receipt" mean a receipt or other
instrument issued by a depository representing an interest in one or more
shares, or fractions thereof, solely of stock of a corporation, which stock is
deposited with the depository.
 
     (b) Appraisal rights shall be available for the shares of any class or
series of stock of a constituent corporation in a merger or consolidation to be
effected pursuant to sec.251 (other than a merger effected pursuant to
sec.251(g) of this title), sec.252, sec.254, sec.257, sec.258, sec.263 or
sec.264 of this title:
 
          (1) Provided, however, that no appraisal rights under this section
     shall be available for the shares of any class or series of stock, which
     stock, or depository receipts in respect thereof, at the record date fixed
     to determine the stockholders entitled to receive notice of and to vote at
     the meeting of stockholders to act upon the agreement of merger or
     consolidation, were either (i) listed on a national securities exchange or
     designated as a national market system security on an interdealer quotation
     system by the National Association of Securities Dealers, Inc. or (ii) held
     of record by more than 2,000 holders; and further provided that no
     appraisal rights shall be available for any shares of stock of the
     constituent corporation surviving a merger if the merger did not require
     for its approval the vote of the holders of the surviving corporation as
     provided in subsection (f) of sec.251 of this title.
 
          (2) Notwithstanding paragraph (1) of this subsection, appraisal rights
     under this section shall be available for the shares of any class or series
     of stock of a constituent corporation if the holders thereof are required
     by the terms of an agreement of merger or consolidation pursuant to
     sec.sec.251, 252, 254, 257, 258, 263 and 264 of this title to accept for
     such stock anything except:
 
             a. Shares of stock of the corporation surviving or resulting from
        such merger or consolidation, or depository receipts in respect thereof;
 
             b. Shares of stock of any other corporation, or depository receipts
        in respect thereof, which shares of stock (or depository receipts in
        respect thereof) or depository receipts at the effective date of the
        merger or consolidation will be either listed on a national securities
        exchange or designated as a national market system security on an
        interdealer quotation system by the National Association of Securities
        Dealers, Inc. or held of record by more than 2,000 holders;
 
             c. Cash in lieu of fractional shares or fractional depository
        receipts described in the foregoing subparagraphs a. and b. of this
        paragraph; or
 
             d. Any combination of the shares of stock, depository receipts and
        cash in lieu of fractional shares or fractional depository receipts
        described in the foregoing subparagraphs a., b. and c. of this
        paragraph.
 
          (3) In the event all of the stock of a subsidiary Delaware corporation
     party to a merger effected under sec.253 of this title is not owned by the
     parent corporation immediately prior to the merger, appraisal rights shall
     be available for the shares of the subsidiary Delaware corporation.
<PAGE>   187
 
     (c) Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets of
the corporation. If the certificate of incorporation contains such a provision,
the procedures of this section, including those set forth in subsections (d) and
(e) of this section, shall apply as nearly as is practicable.
 
     (d) Appraisal rights shall be perfected as follows:
 
          (1) If a proposed merger or consolidation for which appraisal rights
     are provided under this section is to be submitted for approval at a
     meeting of stockholders, the corporation, not less than 20 days prior the
     meeting, shall notify each of its stockholders who was such on the record
     date for such meeting with respect to shares for which appraisal rights are
     available pursuant to subsections (b) or (c) hereof that appraisal rights
     are available for any or all of the shares of the constituent corporations,
     and shall include in such notice a copy of this section. Each stockholder
     electing to demand the appraisal of such stockholder's shares shall deliver
     to the corporation, before the taking of the vote on the merger or
     consolidation, a written demand for appraisal of such stockholder's shares.
     Such demand will be sufficient if it reasonably informs the corporation of
     the identity of the stockholder and that the stockholder intends thereby to
     demand the appraisal of such stockholder's shares. A proxy or vote against
     the merger or consolidation shall not constitute such a demand. A
     stockholder electing to take such action must do so by a separate written
     demand as herein provided. Within 10 days after the effective date of such
     merger or consolidation, the surviving or resulting corporation shall
     notify each stockholder of each constituent corporation who has complied
     with this subsection and has not voted in favor of or consented to the
     merger or consolidation of the date that the merger or consolidation has
     become effective; or
 
          (2) If the merger or consolidation was approved pursuant to sec.228 or
     sec.253 of this title, each constituent corporation, either before the
     effective date of the merger or consolidation or within ten days
     thereafter, shall notify each of the holders of any class or series of
     stock of such constituent corporation who are entitled to appraisal rights
     of the approval of the merger or consolidation and that appraisal rights
     are available for any or all shares of such class or series of stock of
     such constituent corporation, and shall include in such notice a copy of
     this section; provided that, if the notice is given on or after the
     effective date of the merger or consolidation, such notice shall be given
     by the surviving or resulting corporation to all such holders of any class
     or series of stock of a constituent corporation that are entitled to
     appraisal rights. Such notice may, and, if given on or after the effective
     date of the merger or consolidation, shall, also notify such stockholders
     of the effective date of the merger or consolidation. Any stockholder
     entitled to appraisal rights may, within 20 days after the date of mailing
     of the notice, demand in writing from the surviving or resulting
     corporation the appraisal of such holder's shares. Such demand will be
     sufficient if it reasonably informs the corporation of the identity of the
     stockholder and that the stockholder intends thereby to demand the
     appraisal of such holder's shares. If such notice did not notify
     stockholders of the effective date of the merger or consolidation, either
     (i) each constituent corporation shall send a second notice before the
     effective date of the merger or consolidation notifying each of the holders
     of any class or series of stock of such constituent corporation that are
     entitled to appraisal rights of the effective date of the merger or
     consolidation or (ii) the surviving or resulting corporation shall send
     such a second notice to all such holders on or within 10 days after such
     effective date; provided, however, that if such second notice is sent more
     than 20 days following the sending of the first notice, such second notice
     need only be sent to each stockholder who is entitled to appraisal rights
     and who has demanded appraisal of such holder's shares in accordance with
     this subsection. An affidavit of the secretary or assistant secretary or of
     the transfer agent of the corporation that is required to give either
     notice that such notice has been given shall, in the absence of fraud, be
     prima facie evidence of the facts stated therein. For purposes of
     determining the stockholders entitled to receive either notice, each
     constituent corporation may fix, in advance, a record date that shall be
     not more than 10 days prior to the date the notice is given, provided, that
     if the notice is given on or after the effective date of the
 
                                       C-2
<PAGE>   188
 
     merger or consolidation, the record date shall be such effective date. If
     no record date is fixed and the notice is given prior to the effective
     date, the record date shall be the close of business on the day next
     preceding the day on which the notice is given.
 
     (e) Within 120 days after the effective date of the merger or
consolidation, the surviving or resulting corporation or any stockholder who has
complied with subsections (a) and (d) hereof and who is otherwise entitled to
appraisal rights, may file a petition in the Court of Chancery demanding a
determination of the value of the stock of all such stockholders.
Notwithstanding the foregoing, at any time within 60 days after the effective
date of the merger or consolidation, any stockholder shall have the right to
withdraw such stockholder's demand for appraisal and to accept the terms offered
upon the merger or consolidation. Within 120 days after the effective date of
the merger or consolidation, any stockholder who has complied with the
requirements of subsections (a) and (d) hereof, upon written request, shall be
entitled to receive from the corporation surviving the merger or resulting from
the consolidation a statement setting forth the aggregate number of shares not
voted in favor of the merger or consolidation and with respect to which demands
for appraisal have been received and the aggregate number of holders of such
shares. Such written statement shall be mailed to the stockholder within 10 days
after such stockholder's written request for such a statement is received by the
surviving or resulting corporation or within 10 days after expiration of the
period for delivery of demands for appraisal under subsection (d) hereof,
whichever is later.
 
     (f) Upon the filing of any such petition by a stockholder, service of a
copy thereof shall be made upon surviving or resulting corporation, which shall
within 20 days after such service file in the office of the Register in Chancery
in which the petition was filed a duly verified list containing the names and
addresses of all stockholders who have demanded payment for their shares and
with whom agreements as to the value of their shares have not been reached by
the surviving or resulting corporation. If the petition shall be filed by the
surviving or resulting corporation, the petition shall be accompanied by such a
duly verified list. The Register in Chancery, if so ordered by the Court, shall
give notice of the time and place fixed for the hearing of such petition by
registered or certified mail to the surviving or resulting corporation and to
the stockholders shown on the list at the addresses therein stated. Such notice
shall also be given by 1 or more publications at least 1 week before the day of
the hearing, in a newspaper of general circulation published in the City of
Wilmington, Delaware, or such publication as the Court deems advisable. The
forms of the notices by mail and by publication shall be approved by the Court,
and the costs thereof shall be borne by the surviving or resulting corporation.
 
     (g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled to
appraisal rights. The Court may require the stockholders who have demanded an
appraisal for their shares and who hold stock represented by certificates to
submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as to
such stockholder.
 
     (h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any element
of value arising from the accomplishment or expectation of the merger or
consolidation, together with a fair rate of interest, if any, to be paid upon
the amount determined to be the fair value. In determining such fair value, the
Court shall take into account all relevant factors. In determining the fair rate
of interest, the Court may consider all relevant factors, including the rate of
interest which the surviving or resulting corporation would have had to pay to
borrow money during the pendency of the proceeding. Upon application by the
surviving or resulting corporation or by any stockholder entitled to participate
in the appraisal proceeding, the Court may, in its discretion, permit discovery
or other pretrial proceedings and may proceed to trial upon the appraisal prior
to the final determination of the stockholder entitled to an appraisal. Any
stockholder whose name appears on the list filed by the surviving or resulting
corporation pursuant to subsection (f) of this section and who has submitted
such stockholder's certificates of stock to the Register in Chancery, if such is
required, may participate fully in all proceedings until it is finally
determined that such stockholder is not entitled to appraisal rights under this
section.

<PAGE>   189
 
     (i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to the
stockholders entitled thereto. Interest may be simple or compound, as the Court
may direct. Payment shall be so made to each such stockholder, in the case of
holders of uncertificated stock forthwith, and the case of holders of shares
represented by certificates upon the surrender to the corporation of the
certificates representing such stock. The Court's decree may be enforced as
other decrees in the Court of Chancery may be enforced, whether such surviving
or resulting corporation be a corporation of this State or of any state.
 
     (j) The costs of the proceeding may be determined by the Court and taxed
upon the parties as the Court deems equitable in the circumstances. Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorney's fees and the
fees and expenses of experts, to be charged pro rata against the value of all
the shares entitled to an appraisal.
 
     (k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded appraisal rights as provided in subsection (d) of
this section shall be entitled to vote such stock for any purpose or to receive
payment of dividends or other distributions on the stock (except dividends or
other distributions payable to stockholders of record at a date which is prior
to the effective date of the merger or consolidation); provided, however, that
if no petition for an appraisal shall be filed within the time provided in
subsection (e) of this section, or if such stockholder shall deliver to the
surviving or resulting corporation a written withdrawal of such stockholder's
demand for an appraisal and an acceptance of the merger or consolidation, either
within 60 days after the effective date of the merger or consolidation as
provided in subsection (e) of this section or thereafter with the written
approval of the corporation, then the right of such stockholder to an appraisal
shall cease. Notwithstanding the foregoing, no appraisal proceeding in the Court
of Chancery shall be dismissed as to any stockholder without the approval of the
Court, and such approval may be conditioned upon such terms as the Court deems
just.
 
     (l) The shares of the surviving or resulting corporation to which the
shares of such objecting stockholders would have been converted had they
assented to the merger or consolidation shall have the status of authorized and
unissued shares of the surviving or resulting corporation.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Stockholders and Board of Directors of Nabors Industries, Inc.

     We have audited the accompanying consolidated balance sheets of Nabors
Industries, Inc. and Subsidiaries as of September 30, 1997 and 1996, and the
related consolidated statements of income, changes in stockholders' equity, and
cash flows for each of the three years in the period ended September 30, 1997.
These financial statements are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements based
on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Nabors
Industries, Inc. and Subsidiaries as of September 30, 1997 and 1996, and the
consolidated results of their operations and their cash flows for each of the
three years in the period ended September 30, 1997, in conformity with generally
accepted accounting principles.
 
                                             /s/ PRICEWATERHOUSECOOPERS LLP
