                       BAYARD DRILLING TECHNOLOGIES, INC.

                          NOTES TO FINANCIAL STATEMENTS
                                   (Unaudited)

1.   In the opinion of management of Bayard Drilling Technologies, Inc. 
("Bayard" or the "Company"), the unaudited interim financial statements for the
six months ended June 30, 1998 and 1997 include all adjustments, consisting of
normal recurring accruals, necessary to present fairly the Company's financial
position as of June 30, 1998 and results of operations and cash flows for the
six months ended June 30, 1998 and 1997. Results for the period ended June 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.

2.   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.

3.   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.

4.   On October 16, 1997, the Company completed the acquisition of Bonray 
Drilling Corporation ("Bonray Acquisition"), subject to certain working capital
adjustments, for 3,015,000 shares of the Company's Common Stock, par value $0.01
per share (the "Common Stock"). The Bonray Acquisition was accounted for as a
purchase. In the Bonray Acquisition, the Company acquired 13 rigs, including
seven rigs with depth capacities of 15,000 feet or greater and two diesel
electric SCR rigs. At the time of the Bonray Acquisition, twelve of Bonray's
rigs were operating and under contract and one was awaiting refurbishment. On
March 30, 1998, the Securities and Exchange Commission declared effective a
Registration Statement on Form S-1 (Commission File No. 333-43535) pursuant to
which the Company registered 2,955,000 shares of Common Stock in connection with
a registration rights agreement entered into at the time of the Bonray
Acquisition.

5.   In November 1997, the Company and certain of its stockholders consummated
an initial public offering (the "Initial Public Offering"); pursuant to which
the Company registered the sale of an aggregate of 11,040,000 shares of Common
Stock. In the Initial Public Offering, the Company issued and sold 4,229,050
shares of Common Stock and certain stockholders of the Company sold 6,810,950
shares of Common Stock. The Company received net proceeds of $89.5 million for
the shares sold by it in the Initial Public Offering. Through June 30, 1998
these net proceeds have been used as follows: (i) $36.8 million to purchase
machinery and equipment; (ii) $37.5 million to repay indebtedness, including
$6.2 million prepaid in May 1998 on the amount outstanding under the Term Note;
(iii) $817,125 to pay The CIT Group/Equipment Financing, Inc. ("CIT") in
connection with the exercise by CIT of a warrant for 150,000 shares of Common
Stock; and (iv) $14.5 million placed in temporary investments

6.   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"). The purchase was accomplished through the issuance of $100
million of the Company's 11% Senior Notes due 2005 (the "Senior Notes
Offering"). The Company received net proceeds of approximately $97 million, and
will use the additional proceeds for general corporate purposes, possibly
including capital expenditures for acquisitions of additional drilling rigs and
related equipment and the refurbishment of rigs. 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. 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.

7.   Prior to the consummation of the Senior Notes Offering, the Company 
completed a reorganization of its corporate structure and obtained the release
of certain collateral for its secured indebtedness. In the reorganization of the
corporate structure, Bayard and its subsidiaries Trend, Bayard Drilling, L.L.C.
and Bonray transferred substantially all of their drilling rigs, associated
equipment and other assets to a wholly owned partnership, Bayard Drilling, L.P.
("Bayard Drilling"), subject to the transferors' secured indebtedness, in
exchange for the assumption by Bayard Drilling of associated liabilities and the
issuance by Bayard Drilling of partnership interests. Concurrently with the
transfers, (i) the Company's secured lenders under its bank loan arrangements
(consisting of a term loan and a revolving loan) released from liens securing
the term loan all assets except 12 drilling rigs and associated equipment and
released from liens securing the revolving loan all drilling rigs and drilling
contracts, except the 12 rigs remaining as collateral under the term loan and
the drilling contracts associated with those 12 rigs, (ii) Bayard Drilling and
its general partner Bayard Drilling, L.L.C. issued guarantees in favor of the
lenders and (iii) the Company repaid approximately $6.2 million of its
indebtedness to the lenders under its term loan. The Company recorded an
extraordinary loss of $338,000 (net of income tax effect of $245,000) in the
second quarter of 1998 relating to 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 the IPO.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS

GENERAL

         The Company is a leading provider of contract land drilling services to
major and independent oil and gas companies. The Company was formed in December
1996 through a series of transactions (the "Formation Transactions") that
established the Company as a regional competitor with ten rigs. Since that time,
the Company has grown to operate the fifth largest land drilling fleet in the
United States with a total of 88 rigs, 73 of which are currently being marketed.
This growth is due primarily to, and the Company's operations have been
significantly affected by, the following transactions:

         o Trend Acquisition. In May 1997, the Company completed the acquisition
of Trend Drilling Co. and its 14 rigs ("Trend") for $18 million in cash and
250,000 shares of the Company's common stock, par value $0.01 per share (the
"Common Stock") (the "Trend Acquisition").

         o Ward Acquisition. Also in May 1997, the Company acquired the assets
of Ward Drilling Company, Inc. including six rigs ("Ward") for $8 million in
cash, 400,000 shares of Common Stock and warrants to purchase an additional
200,000 shares of Common Stock (the "Ward Acquisition").

         o Bonray Acquisition. In October 1997, the Company acquired Bonray
Drilling Corporation ("Bonray") from DLB Oil & Gas, Inc. ("DLB") for 3,015,000
shares of Common Stock (the "Bonray Acquisition"). In the Bonray Acquisition,
the Company acquired 13 rigs, including seven rigs with depth capacities of
15,000 feet or greater and two diesel electric silicon controlled rectifier
rigs.

         o  Oliver  Acquisition.  On January 9, 1998, the Company  purchased 
six additional rigs from R. T. Oliver Drilling, Inc. for approximately $14
million in cash (the "Oliver Acquisition"). The Company expects to refurbish and
purchase complementary equipment, including drill pipe, for these rigs as market
conditions warrant.

         o Individual Rig Acquisitions. In addition to the Trend, Ward, Bonray
and Oliver Acquisitions, the Company has invested $5.5 million to acquire six
rigs in five transactions involving purchases of individual rigs or rig
components (the "Individual Rig Acquisitions" and, together with the Formation
Transactions and the Trend, Ward, Bonray and Oliver Acquisitions, the
"Consolidation Transactions"). In addition, the Company has purchased on rig for
approximately $54,000 and has two rigs, which may be assembled from inventoried
components. In August 1997, the Company sold one rig.


                                       6
<PAGE>   9

         o  Initial  Public  Offering.  In November  1997, the Company 
completed an initial public offering (the "Initial Public Offering ") of
11,040,000 shares of Common Stock. The Company sold 4,229,050 shares of Common
Stock in the Initial Public Offering and received net proceeds of $89.5 million.

         o Refurbishment. The Consolidation Transactions included a number of
rigs in need of refurbishment. From January 1, 1997 through June 30, 1998, the
Company 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 June 30, 1998, the
Company had 15 additional rigs in various stages of refurbishment. The Company
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.
The Company anticipates refurbishing and placing the remaining 15 rigs into
service as market conditions warrant.

         o TransTexas Acquisition. In June 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"). This transaction was financed through an offering
(the "Senior Notes Offering") of $100 million of the Company's 11% Senior Notes
due 2005.

         The historical financial results presented herein include the effects
of the foregoing transactions and the operations of the related rigs only for
the periods after such transactions. In addition, the historical financial
results include periods in which a number of rigs were being refurbished and did
not contribute to revenues. Accordingly, the Company does not believe that the
historical statements of operations presented herein are necessarily indicative
of the Company's future operating results, or that comparisons of financial
results between the periods presented herein are necessarily meaningful,
particularly in light of the magnitude of the Company's recent acquisitions and
rig refurbishment projects. This discussion and analysis should be read in
conjunction with the consolidated financial statements of the Company and notes
thereto included elsewhere herein and the Company's Annual Report on Form 10-K
for the year ended December 31, 1997.

DOMESTIC LAND DRILLING INDUSTRY OVERVIEW

         Demand for the Company'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.

         The Company's operating margins are influenced by contract drilling
rates, operating costs and drilling rig utilization. Although the Company
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. The recent decline in oil and gas
prices has contributed to a decrease in the Company's rig utilization rates from
88% for the fourth quarter of 1997 to 72% for the second 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 the Company'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. The
Company 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, the Company has completed the Consolidation
Transactions and in June 1998 consummated the TransTexas Acquisition. The
Formation Transactions involved the issuance of an aggregate of 5,600,000 shares
of Common Stock in consideration for the contribution to the Company of 16 rigs
and $10 million in cash. At the time of the Formation Transactions, the Company
entered into a $24 million term loan facility with The CIT Group/Equipment
Financing, Inc. ("CIT"), principally for the refurbishment of certain of the
Company's rigs. In May 1997, contemporaneously with the Trend Acquisition and in
anticipation of the Ward Acquisition, the 


                                       7
<PAGE>   10

Company completed a financing transaction in which it (i) issued to Chesapeake
Energy Corporation ("Chesapeake") and Energy Spectrum Partners LP ("Energy
Spectrum") additional shares of Common Stock, and two series of warrants
together with subordinated notes due May 1, 2003 (the "Subordinated Notes") for
$28.5 million in cash and (ii) increased the availability under its debt
facilities from $24 million to $40.5 million.

         In November 1997, the Company and certain of its stockholders
consummated the Initial Public Offering, pursuant to which the Company
registered the sale of an aggregate of 11,040,000 shares of Common Stock. In the
Initial Public Offering, the Company issued and sold 4,229,050 shares of Common
Stock and certain stockholders of the Company sold 6,810,950 shares of Common
Stock. The Company received net proceeds of $89.5 million for the shares sold by
it in the Initial Public Offering. Through June 30, 1998 these net proceeds have
been used as follows: (i) $36.8 million to purchase machinery and equipment;
(ii) $37.5 million to repay indebtedness, including $6.2 million prepaid in May
1998 on the amount outstanding under the Term Loan (as herein defined); (iii)
$817,125 to pay CIT in connection with the exercise of certain options to
purchase Common Stock; and (iv) $14.5 million placed in temporary investments.

         Currently, the Company's primary bank debt facilities consist of a term
loan (the "Term Loan") under an agreement (the "Term Loan Agreement") with CIT
and Fleet Capital Corporation ("Fleet"), under which $17.9 million was
outstanding as of June 30, 1998 and a $10 million revolving loan facility under
an agreement (the "Revolving Loan Agreement" and, together with the Term Loan
Agreement, the "Loan Agreements") with Fleet under which the Company has no
outstanding borrowings other than approximately $1.3 million in letters of
credit as of June 30, 1998. On June 26, 1998, the Company issued $100 million of
its 11% Senior Notes due 2005 (together with any registered notes issued in
exchange therefor, the "Senior Notes") and used $75 million of such proceeds to
fund the TransTexas Acquisition. Further information regarding the Loan
Agreements and the Senior Notes is set forth below under "Financing Activities."

         The Company'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 June 30, 1998, the Company 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 $89 million on refurbishments and
other related equipment purchases, including drill pipe, and $75 million on the
TransTexas Acquisition. As a result, the Company's net property and equipment
increased from $27 million at December 31, 1996 to $155.7 million at December
31, 1997 and $269.1 million at June 30, 1998. The Company's principal sources of
liquidity have been the issuance of Common Stock, the Senior Notes, warrants to
purchase Common Stock and the Subordinated Notes and borrowings under the Loan
Agreements. As of June 30, 1998 the Company has $100 million principal amount of
Senior Notes outstanding as a result of the Senior Notes Offering, $17.9 million
of borrowings outstanding under the Term Loan Agreement, no borrowings
outstanding under the Revolving Loan Agreement and no outstanding Subordinated
Notes. The Company expects to fund its capital requirements for 1998 through the
application of the remaining proceeds from the Initial Public Offering and the
Senior Notes Offering, cash flow from operations, and, to the extent required,
borrowings under the Loan Agreements. The Company believes that such sources of
funds will be sufficient to meet the Company's anticipated uses for 1998.

         The most significant change in the Company's balance sheet from
December 31, 1997 to June 30, 1998 was a $113.4 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 $8.4
million and stockholders' equity increased by $2.3 million.

         From December 31, 1997 to June 30, 1998, the Company's working capital
position decreased by $22.3 million to $26.6 million. This was primarily the
result of additions to fixed assets.

Operating Activities

         During the six months ended June 30, 1998, net cash provided from
operating activities totaled $22 million. The Company generated cash from
operations of $10.2 million and working capital changes provided $11.8 million.


                                       8
<PAGE>   11

Investing Activities

         During the six months ended June 30, 1998, the Company invested $120
million in fixed assets, including $11.1 million in the Oliver Acquisition, and
$75 million in the TransTexas Acquisition. Rig refurbishments including Oliver
Acquisition costs of $11.1 million, refurbishments of $11.6 million on rigs
currently being marketed, and $12.6 million of equipment for future
refurbishment programs totaled $35.3 million. Total investment in drill pipe was
$4.6 million.

Financing Activities

         During the six months ended June 30, 1998, the Company's payments under
the Loan Agreements totaled $11.9 million.

         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.

         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 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. 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.

         The Company had outstanding at June 30, 1998 $17.9 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.


                                       9
<PAGE>   12


         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 (9.91% at June 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 June
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.

         The Company also has issued three amortizing term notes (the "Top Drive
Notes") totaling approximately $2.8 million outstanding at June 30, 1998. This
debt bears interest at 9.5% per annum and is collateralized by certain equipment
(top drives) of the Company 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.

Other Matters

         The Company continues to actively review possible acquisition
opportunities. While the Company has not entered into any definitive agreements
to acquire additional businesses or material equipment, suitable opportunities
may arise in the future. The timing or success of any acquisition effort and the
size of the associated potential capital commitments cannot be predicted at this
time. In addition, there can be no assurance that adequate funding will be
available on terms satisfactory to the Company.

         total number of rig days worked by the Company's drilling rig fleet
         marketed during the period.

(3)      Drilling costs exclude depreciation and amortization and general and
         administrative expenses.

         Drilling revenues increased approximately $9.2 million, or 84% to $20.2
million for the three months ended June 30, 1998, from $11 million for the three
months ended June 30, 1997. Drilling revenues increased due to a 1,436 day, or
78%, increase in rig days worked, and a $211, or 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 June 30, 1998, the
Company 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 679 days worked in the Gulf Coast region, 2,579 days worked
in the Mid-Continent region, and 30 days worked 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 the Company, offset
by a decrease in the utilization rate from 95 % to 72%.

         Drilling costs increased by approximately $7.4 million, or 94%, to
$15.2 million for the three months ended June 30, 1998, from $7.9 million for
the three months ended June 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 1,436 day increase in the days
worked.

         The Company's operating margin increased by approximately $1.8 million,
or 58%, to $5 million for the three months ended June 30, 1998, as compared to
$3.1 million for the three months ended June 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 $1.5 million, or
87%, to $3.3 million for the three months ended June 30, 1998, as compared to
$1.8 million for the three months ended June 30, 1997. The increase was
primarily due to additional depreciation associated with the Consolidation
Transactions.

         General and administrative expense increased by $175,000, or 32%, to
$714,000 for the three months ended June 30, 1998, from $539,000 for the same
period of 1997 due primarily to increased payroll costs associated 


                                       11

with new management and increased corporate staff and increased legal fees due
to the Company's acquisition activities and public status.

         Interest expense was $201,000 for the three months ended June 30, 1998
as compared to $837,000 for the three months ended June 30, 1997 due to
capitalized interest during the three months ended June 30, 1998 due to rig
refurbishments.

         Other income increased for the three months ended June 30, 1998 as
compared to the three months ended June 30, 1997, primarily due to interest
income received on funds being invested in short-term investments and the gain
recognized on the sale of assets at auction.

         For the three months ended June 30, 1998, the income tax provision was
$535,000 compared to $39,000 for the first three months of 1997. This increase
is due to the increase in net income for the three months ended June 30, 1998
versus the same period one-year ago.

         For the three months ended June 30, 1998, the Company 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 the IPO.

(4)      Rig days worked represents the number of rigs being marketed by the
         Company 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.

(5)      Represents total contract drilling revenues (including mobilization
         revenues and reimbursement for fuel and other costs) divided by the
         total number of rig days worked by the Company's drilling rig fleet
         marketed during the period.

(6)      Drilling costs exclude depreciation and amortization and general and
         administrative expenses.

         Drilling revenues increased approximately $29.1 million, or 192% to
$44.2 million for the six months ended June 30, 1998, from $15.1 million for the

Texas region. Increases in revenues per day were a result of the increase in the
dayrates and the average number of land drilling rigs being marketed by the
Company, offset by a decrease in the utilization rate from 96% to 78%.

         Drilling costs increased by approximately $21.6 million, or 198%, to
$32.5 million for the six months ended June 30, 1998, from $10.9 million for the
six months ended June 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 4,361 day increase in the days worked.

         The Company's operating margin increased by approximately $7.5 million,
or 178%, to $11.8 million for the six months ended June 30, 1998, as compared to
$4.2 million for the six months ended June 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 $3.8 million, or
145%, to $6.5 million for the six months ended June 30, 1998, as compared to
$2.6 million for the six months ended June 30, 1997. The increase was primarily
due to additional depreciation associated with the Consolidation Transactions.

         General and administrative expense increased by $735,000, or 100%, to
$1,469,000 for the six months ended June 30, 1998, from $734,000 for the same
period of 1997 due primarily to increased payroll costs associated with new
management and increased corporate staff and increased legal fees due to the
Company's acquisition activities and public status.

         Interest expense was $568,000 for the six months ended June 30, 1998 as
compared to $982,000 for the six months ended June 30, 1997 due to the
capitalization of interest during the six months ended June 30, 1998 for rigs in
process of rig refurbishment.

         Other income increased for the six months ended June 30, 1998 as
compared to the six months ended June 30, 1997, primarily due to interest income
received on funds being invested in short-term investments and the gain
recognized on the auction sale of assets.

         For the six months ended June 30, 1998, the income tax provision was
$1.8 million compared to $12,000 for the first six months of 1997. This increase
is due to the increase in net income for the first six months of June 1998
versus the first six months of 1997.

         For the six months ended June 30, 1998, the Company 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 the IPO.


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

         The Company has reviewed its computer systems and hardware to locate
potential operational problems associated with the year 2000. Such review will
continue until all potential problems are located and resolved. The Company
believes that all year 2000 problems in its computer systems have been or will
be resolved in a timely manner and have not caused and will not cause disruption
of its operations or have a material adverse effect on its financial condition
or results of operations. However, it is possible that the Company's cash flows
could be disrupted by year 2000 problems experienced by its customers, financial
institutions or other persons. The Company is unable to quantify the effect, if
any, of year 2000 computer problems that may be experienced by these third
parties.

                           PART II. OTHER INFORMATION


ITEM 1.           LEGAL PROCEEDINGS.

         A purported class action lawsuit is pending against the Company,
certain directors and officers of the Company, the 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 et al. 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 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 under the
Securities Act of 1933 and the Oklahoma 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, and would negatively impact the Company's
liquidity. In each of these lawsuits, the 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 joined in Yuan's motion to be appointed as lead plaintiffs in the
Yuan federal court suit. In connection with the dismissal of the Khan and
Burkett cases, the Company withdrew its opposition to the motion for appointment
of lead plaintiffs filed by various plaintiffs in the Yuan case. On May 12,
1998, the court entered an order appointing approximately 20 individuals as lead
plaintiffs in the Yuan case, and appointing various law firms as attorneys for
the lead plaintiffs. The lead plaintiffs filed an amended complaint on July 30,
1998, and the Company and the other defendants have until September 11, 1998 to
respond to the amended complaint.

         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 Bayard and Sperry-Sun Drilling Services, Inc. on
May 29, 1998 in the District Court of Oklahoma County in the State of Oklahoma.
R.C. Taylor Companies, Inc., the plaintiff in that lawsuit, seeks actual and
punitive damages for costs allegedly incurred in connection with a directional
drilling project that utilized one of the Company's rigs.

         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.

ITEM 2.           CHANGES IN SECURITIES AND USE OF PROCEEDS

         On June 26, 1998, the Company issued $100 million principal amount of
its 11% Senior Notes due 2005. The terms of the Senior Notes are governed by an
Indenture, dated June 26, 1998 (the "Indenture"), between the Company, the
Guarantors and U.S. Trust Company of Texas, N.A., as trustee. The Indenture
imposes certain operating and financial restrictions on the Company, including
limitations on the Company's ability to pay dividends or make other
distributions on the Common Stock. For further details regarding restrictions
imposed on the Company by the Indenture and the Senior Notes that may affect the
rights of the holders of Common Stock, reference is made to the Indenture, a
copy of which has been filed with the Commission as an exhibit to this Report.

         On November 3, 1997, the Securities and Exchange Commission declared
effective two Registration Statements on Form S-1 (Commission File Nos.
333-34451 and 333-39393) pursuant to which the Company registered the sale of an
aggregate of 11,040,000 shares of Common Stock. The Initial Public Offering
commenced on November 4, 1997 and was concluded promptly thereafter by the sale
of all 11,040,000 of the registered shares. Of the 11,040,000 shares of Common
Stock registered in the Initial Public Offering, 4,229,050 shares were sold by
the Company for an aggregate offering price of $97,268,150 and an aggregate of
6,810,950 shares were sold by certain stockholders for an aggregate offering
price of $156,651,850.

         After deducting expenses of approximately $7,765,600, the net proceeds
to the Company from the Initial Public Offering were $89.5 million. Through June
30, 1998, the net proceeds received by the Company in the Initial Public
Offering have been used for the following purposes:

(1)      Such funds are currently being invested in short-term instruments until
         they are required for the purposes described in the prospectus related
         to the Initial Public Offering. The Company repaid 25% ($6.2 million)
         of the amount outstanding under the Term Loan from a portion of the
         temporary investments on May 14, 1998.

         None of the aforementioned expenses or uses of proceeds constituted
direct or indirect payments to directors or officers of the Company or their
associates, to persons owning 10% or more of any class of equity securities of
the Company or to any affiliates of the Company.

                AMENDED AND RESTATED LOAN AND SECURITY AGREEMENT

         THIS AMENDED AND RESTATED LOAN AND SECURITY AGREEMENT is made this
18th day of June, 1998, by and between FLEET CAPITAL CORPORATION ("Lender"), a
Rhode Island corporation with an office at 2711 North Haskell Avenue, Suite
2100, LB 21, Dallas, Texas 75204, and Bayard Drilling Technologies, Inc., a
Delaware corporation ("Bayard" or "Borrower"), with its chief executive office
and principal place of business at 4005 N.W. Expressway, Oklahoma City,
Oklahoma 73116 and joined in by Bayard Drilling, L.P., a Delaware limited
partnership ("Drilling LP") for the purposes described in Section 11.21 below
(the "Agreement").  Capitalized terms used in this Agreement have the meanings
assigned to them in Appendix A, General Definitions.  Accounting terms not
otherwise specifically defined herein shall be construed in accordance with
GAAP consistently applied.

SECTION 1.       CREDIT FACILITY

         Subject to the terms and conditions of, and in reliance upon the
representations and warranties made in, this Agreement and the other Loan
Documents, Lender agrees to make a total credit facility of up to $10,000,000
available upon Borrower's request therefor, as follows:

         1.1     Revolving Credit Loans.

                 1.1.1    Loans and Reserves.  Lender agrees, during the term
of this Agreement and for so long as no Default or Event of Default exists, to
make Revolving Credit Loans to Borrower from time to time, as requested by
Borrower in the manner set forth in Section 3.1.1 hereof, up to a maximum
principal amount at any time outstanding equal to the Borrowing Base.  Lender
shall have the right to establish reserves in such amounts, and with respect to
such matters, as Lender shall deem necessary or appropriate, against the amount
of Revolving Credit Loans which Borrower may otherwise request under this
Section 1.1.1, including, without limitation, with respect to (i) any sums
chargeable against Borrower's Loan Account as Revolving Credit Loans under any
section of this Agreement; (ii) amounts owing by Borrower and/or Drilling LP to
any Person to the extent secured by a Lien on, or trust over, any Property of
Borrower and/or Drilling LP other than the CIT Debt; (iii) all amounts of past
due rent or other charges owing at such time by Borrower and/or Drilling LP to
any landlord of any premises where any of the Collateral is located; and (iv)
such other matters, events, conditions or contingencies as to which Lender, in
its reasonable judgment, determines reserves should be established from time to
time hereunder.

                 1.1.2    Use of Proceeds.  The Revolving Credit Loans shall be
used solely for general corporate purposes and capital needs of the Borrower
and its Subsidiaries, in a manner consistent with the provisions of this
Agreement and Applicable Law.  In no event shall any proceeds of any Revolving
Credit Loans be used to purchase or to carry, reduce, retire or refinance any
Indebtedness incurred to purchase or carry any margin stock (within the meaning
of Regulations G or U of the Federal Reserve Board).


                                      1
<PAGE>   7
         1.2     Letters of Credit; LC Guaranties.  Lender agrees, for so long
as no Default or Event of Default exists and if requested by Borrower, to (i)
issue its, or cause to be issued by its Affiliates, standby Letters of Credit
for the account of Borrower or (ii) execute LC Guaranties by which Lender or
its Affiliates shall guaranty the payment or performance by Borrower of its
reimbursement obligations with respect to standby Letters of Credit, provided
that the LC Amount at any time shall not exceed $2,000,000.  No Letter of
Credit or LC Guaranty may have an expiration date that is after the last day of
the Original Term.  Any amounts paid by Lender under any LC Guaranty or in
connection with any Letter of Credit shall be treated as Revolving Credit
Loans, shall be secured by all of the Collateral and shall bear interest and be
payable at the same rate and in the same manner as Revolving Credit Loans.

         1.3     All Loans to Constitute One Obligation.  All Loans shall
constitute one general obligation of Borrower, and shall be secured by Lender's
security interest in and Lien upon all of the Collateral, and by all other
security interests and Liens heretofore, now or at any time or times hereafter
granted by Borrower or any Subsidiary to Lender.

         1.4     Release of Trend.  Trend is hereby released from its
obligations under the Original Loan Agreement.  Such release shall not affect
Trend's obligations as Guarantor or party to a Security Agreement.

SECTION 2.       INTEREST, FEES AND CHARGES

         2.1     Interest.

                 2.1.1    Rates of Interest.  The outstanding principal amount
of the Loans shall bear interest at a fluctuating rate per annum equal to the
lesser of (a) one and one-half percent (1.5 %) above the Base Rate (the
"Applicable Annual Rate") and (b) the Maximum Legal Rate.  The rate of interest
applicable to all Loans shall increase or decrease by an amount equal to any
increase or decrease in the Base Rate, effective as of the opening of business
on the day that any such change in the Base Rate occurs.

                 2.1.2    Default Rate of Interest.  Upon and after the
occurrence of an Event of Default, and during the continuation thereof, the
principal amount of all Loans shall bear interest at a rate per annum equal to
the lesser of (a) two percent (2.00%) above the Applicable Annual Rate and (b)
the Maximum Legal Rate.

                 2.1.3    Maximum Interest.  (A)  Notwithstanding anything to
the contrary in this Agreement or otherwise, (i) if at any time the amount of
interest computed on the basis of an Applicable Annual Rate or a Default Rate
would exceed the amount of such interest computed upon the basis of the maximum
rate of interest permitted by applicable state or federal law in effect from
time to time hereafter (the "Maximum Legal Rate"), the interest payable under
this Agreement shall be computed upon the basis of the Maximum Legal Rate, but
any subsequent reduction in such Applicable Annual Rate or Default Rate, as
applicable, shall not reduce such interest thereafter payable hereunder below
the amount computed on the basis of the Maximum Legal Rate until the aggregate
amount of such interest accrued and payable under this Agreement





                                       2
<PAGE>   8
equals the total amount of interest which would have accrued if such interest
had been at all times computed solely on the basis of an Applicable Annual Rate
or Default Rate, as applicable; and (ii) unless preempted by federal law, an
Applicable Annual Rate or Default Rate, as applicable, from time to time in
effect hereunder may not exceed the applicable "annual ceiling" as defined in
Chapter 303, Optional Interest Rate Ceilings of the Texas Finance Code.  If the
applicable state or federal law is amended in the future to allow a greater
rate of interest to be charged under this Agreement than is presently allowed
by applicable state or federal law, then the limitation of interest hereunder
shall be increased to the maximum rate of interest allowed by applicable state
or federal law as amended, which increase shall be effective hereunder on the
effective date of such amendment, and all interest charges owing to Lender by
reason thereof shall be payable in accordance with Section 3.2.2 hereof.

                          (B)     Excess Interest.  No agreements, conditions,
provisions or stipulations contained in this Agreement or any other instrument,
document or agreement between Borrower and Lender or default of Borrower, or
the exercise by Lender of the right to accelerate the payment of the maturity
of principal and interest, or to exercise any option whatsoever contained in
this Agreement or any other Loan Document, or the arising of any contingency
whatsoever, shall entitle Lender to  contract for, charge, or receive, in any
event, interest exceeding the Maximum Legal Rate.  In no event shall Borrower
be obligated to pay interest exceeding such Maximum Legal Rate and all
agreements, conditions or stipulations, if any, which may in any event or
contingency whatsoever operate to bind, obligate or compel Borrower to pay a
rate of interest exceeding the Maximum Legal Rate, shall be without binding
force or effect, at law or in equity, to the extent only of the excess of
interest over such Maximum Legal Rate.  In the event any interest is contracted
for, charged or received in excess of the Maximum Legal Rate ("Excess
Interest"), Borrower acknowledges and stipulates that any such contract,
charge, or receipt shall be the result of an accident and bona fide error, and
that any Excess received by Lender shall be applied, first, to reduce the
principal then unpaid hereunder; second, to reduce the other Obligations; and
third, returned to Borrower, it being the intention of the parties hereto not
to enter at any time into a usurious or otherwise illegal relationship.
Borrower recognizes that, with fluctuations in the Base Rate and the Maximum
Legal Rate, such a result could inadvertently occur.  By the execution of this
Agreement, Borrower covenants that (i) the credit or return of any Excess
Interest shall constitute the acceptance by Borrower of such Excess Interest,
and (ii) to the extent permitted by law, Borrower shall not seek or pursue any
other remedy, legal or equitable, against Lender, based in whole or in part
upon contracting for, charging or receiving of any interest in excess of the
maximum authorized by applicable law.  For the purpose of determining whether
or not any Excess Interest has been contracted for, charged or received by
Lender, all interest at any time contracted for, charged or received by Lender
in connection with this Agreement shall be amortized, prorated, allocated and
spread in equal parts during the entire term of this Agreement.

                          (C)   Incorporation by this Reference.  The
provisions of Section 2.1.3(B) shall be deemed to be incorporated into every
document or communication relating to the Obligations which sets forth or
prescribes any account, right or claim or alleged account, right or claim of
Lender with respect to Borrower (or any other obligor in respect of Obligations
including, without limitation, Drilling LP), whether or not any provision of
Section 2.1.3(B) is





                                       3
<PAGE>   9
referred to therein.  All such documents and communications and all figures set
forth therein shall, for the sole purpose of computing the extent of the
Obligations of Borrower (or any other obligor) asserted by Lender thereunder,
be automatically re-computed by Borrower or any such obligor, and by any court
considering the same, to give effect to the adjustments or credits required by
Section 2.1.3(B).

         2.2     Computation of Interest and Fees.  Interest, Letter of Credit
and LC Guaranty fees and commitment fees hereunder shall be calculated daily
and shall be computed on the actual number of days elapsed over a year of 360
days.  For the purpose of computing interest hereunder, all items of payment
received by Lender shall be deemed applied by Lender on account of the
Obligations (subject to final payment of such items) one (1) Business Day after
receipt by Lender of such items in Lender's account located in Atlanta,
Georgia, and Lender shall be deemed to have received such items of payment on
the date specified in Section 3.3 hereof.

         2.3     Amendment Fee.  Borrower shall pay to Lender, on the Amendment
Date, an amendment fee in the amount of $20,000.

         2.4     Letter of Credit and LC Guaranty Fees.  Borrower shall pay to
Lender for standby Letters of Credit and LC Guaranties of standby Letters of
Credit, two percent (2.00%) per annum of the aggregate face amount of such
Letters of Credit and LC Guaranties outstanding from time to time during the
term of this Agreement, plus all normal and customary charges associated with
the issuance thereof, which fees and charges shall be deemed fully earned upon
issuance of each such Letter of Credit or LC Guaranty, shall be due and payable
on the first Business Day of each month and shall not be subject to rebate or
proration upon the termination of this Agreement for any reason.

         2.5     Commitment Fee.  Borrower shall pay to Lender a commitment fee
equal to one-half of one percent (.5%) per annum of the amount by which the
Average Monthly Revolving Credit Loan Balance is less than the Total Credit
Facility.  The commitment fee shall be payable monthly, in arrears, on the last
day of each calendar month hereafter.

         2.6     Servicing Fee.  Borrower shall pay to Lender an annual
servicing fee of  $20,000.  This servicing fee shall be paid in equal
installments of $5,000, payable on the first day of each April, July, October,
and January thereafter.

         2.7     Audit and Appraisal Fees.  Borrower shall reimburse Lender for
all actual out-of-pocket costs and expenses incurred by Lender in connection
with audits and appraisals of Borrower and/or any Subsidiary's books and
records and such other matters as Lender shall deem appropriate.  All such
out-of-pocket expenses shall be payable on demand.

         2.8     Reimbursement of Expenses.  If, at any time or times
regardless of whether or not an Event of Default then exists, Lender incurs
reasonable legal expenses or any accounting expenses or any other costs or
out-of-pocket expenses in connection with (i) the negotiation and preparation
of this Agreement or any of the other Loan Documents, any amendment of or
modification of this Agreement or any of the other Loan Documents, or any sale
or attempted





                                       4
<PAGE>   10
sale of any interest herein to any other Person; (ii) the administration of
this Agreement or any of the other Loan Documents and the transactions
contemplated hereby and thereby; (iii) any litigation, contest, dispute, suit,
proceeding or action (whether instituted by Lender, Borrower or any other
Person) in any way relating to the Collateral, this Agreement or any of the
other Loan Documents or Borrower's or any Loan Party's affairs; (iv) any
attempt to enforce any rights of Lender against Borrower or any other Person
which may be obligated to Lender by virtue of this Agreement or any of the
other Loan Documents, including the Account Debtors; or (v) any attempt to
inspect, verify, protect, preserve, restore, collect, sell, liquidate or
otherwise dispose of or realize upon the Collateral; then all such legal and
accounting expenses, other costs and out of pocket expenses of Lender shall be
charged to Borrower.  All amounts chargeable to Borrower under this Section 2.8
shall be Obligations secured by all of the Collateral, shall be payable on
demand to Lender and shall bear interest from the date such demand is made
until paid in full at the rate applicable to Revolving Credit Loans from time
to time.  Borrower shall also reimburse Lender for expenses incurred by Lender
in its administration of the Collateral to the extent and in the manner
provided in Section 6 hereof.

         2.9     Bank Charges.  Borrower shall pay to Lender, on demand, any
and all normal and customary fees, costs or expenses which Lender pays to a
bank or other similar institution arising out of or in connection with (i) the
forwarding to Borrower or any other Person on behalf of Borrower, by Lender, of
proceeds of loans made by Lender to Borrower pursuant to this Agreement and
(ii) the depositing for collection, by Lender, of any check or item of payment
received or delivered to Lender on account of the Obligations.

         2.10    Line Debit for Charges.  Lender may, at its option, make a
Revolving Credit Loan to reimburse itself for any and all amounts payable by
Borrower to Lender hereunder.  Alternatively, Lender may invoice Borrower for
any such amounts and, in such case and notwithstanding anything contained
herein to the contrary, interest shall not begin to accrue on such amounts
until five (5) days after the delivery by Lender of such invoice.

SECTION 3.       LOAN ADMINISTRATION

         3.1     Manner of Borrowing Revolving Credit Loans.  Borrowings under
the credit facility established pursuant to Section 1 hereof shall be as
follows:

                 3.1.1    Loan Requests.  A request for a Revolving Credit Loan
shall be made, or shall be deemed to be made, in the following manner:  (i)
Borrower shall give Lender notice of its intention to borrow, in which notice
Borrower shall specify the amount of the proposed borrowing and the proposed
borrowing date, no later than 11:00 a.m. Dallas, Texas time on the proposed
borrowing date; provided, however, Lender shall have the right to refuse to
accept such a request or make a Revolving Credit Loan if at such time there
exists a Default or an Event of Default; and (ii) the becoming due of any
amount required to be paid under this Agreement or under any of the other Loan
Documents, whether as principal, accrued interest, fees or other charges, shall
be deemed irrevocably to be a request by Borrower from Lender for a Revolving
Credit Loan on the due date of, and in an aggregate amount required to pay,
such principal, accrued interest, fees or other charges, and the proceeds of
any such Revolving Credit Loan may





                                       5
<PAGE>   11
be disbursed by Lender by way of direct payment of the relevant Obligation
(whether or not any Default, Event of Default or Out-of-Formula Condition
exists at the time of or would result from such Revolving Credit Loan) and
shall bear interest at the rate of interest applicable to Revolving Credit
Loans.  As an accommodation to Borrower, Lender may permit telephonic requests
for loans and electronic transmittal of instructions, authorizations,
agreements or reports to Lender by Borrower.  Unless Borrower specifically
directs Lender in writing not to accept or act upon telephonic or electronic
communications from Borrower, Lender shall have no liability to Borrower for
any loss or damage suffered by Borrower as a result of Lender's honoring of any
requests, execution of any instructions, authorizations or agreements or
reliance on any reports communicated to Lender telephonically or electronically
and purporting to have been sent to Lender by any individual from time to time
designated by Borrower as an authorized officer and Lender shall have no duty
to verify the origin or authenticity of any such communication.

                 3.1.2    Disbursement.  Borrower hereby irrevocably authorizes
Lender to disburse the proceeds of each Revolving Credit Loan requested, or
deemed to be requested, pursuant to  this Section 3.1.2 as follows:  (i) the
proceeds of each Revolving Credit Loan requested under Section 3.1.1(i) shall
be disbursed by Lender in lawful money of the United States of America in
immediately available funds, by wire transfer to such bank account as may be
agreed upon by Borrower and Lender from time to time or elsewhere if pursuant
to a written direction from Borrower; and (ii) the proceeds of each Revolving
Credit Loan requested under Section 3.1.1(ii) shall be disbursed by Lender by
way of direct payment of the relevant interest or other Obligation.

                 3.1.3    Authorization.  Borrower hereby irrevocably
authorizes Lender, in Lender's sole discretion, to advance to Borrower, and to
charge to Borrower's Loan Account hereunder as a Revolving Credit Loan, a sum
sufficient to pay all interest accrued on the Obligations during the
immediately preceding month and to pay all costs, fees and expenses at any time
owed by Borrower to Lender hereunder.

         3.2     Payments.  All payments with respect to any of the Obligations
shall be made to Lender on the date when due, in Dollars and in immediately
available funds, without any offset or counterclaim.  Except where evidenced by
notes or other instruments issued or made by Borrower to Lender specifically
containing payment provisions which are in conflict with this Section 3.2 (in
which event the conflicting provisions of said notes or other instruments shall
govern and control), the Obligations shall be payable as follows:

                 3.2.1    Principal.  Principal payable on account of Revolving
Credit Loans shall be payable by Borrower to Lender immediately upon the
earliest of (i) the receipt by Lender, Borrower or any other Loan Party of any
proceeds of any of the Collateral, to the extent of said proceeds, (ii) the
occurrence of an Event of Default in consequence of which Lender elects to
accelerate the maturity and payment of the Obligations, or (iii) termination of
this Agreement pursuant to Section 4 hereof; provided, however, that if an
Out-of-Formula Condition shall exist at any time, Borrower shall, on demand,
repay the Obligations to the extent necessary to eliminate the Out-of-Formula
Condition.





                                       6
<PAGE>   12
                 3.2.2    Interest.  Interest accrued on the Revolving Credit
Loans shall be due on the earliest of (i) the first calendar day of each month
(for the immediately preceding month), computed through the last calendar day
of the preceding month, (ii) the occurrence of an Event of Default in
consequence of which Lender elects to accelerate the maturity and payment of
the Obligations or (iii) termination of this Agreement pursuant to Section 4
hereof.

                 3.2.3    Costs, Fees and Charges.  Costs, fees and charges
payable pursuant to this Agreement shall be payable by Borrower as and when
provided in Section 2 hereof, to Lender or to any other Person designated by
Lender in writing.

                 3.2.4    Other Obligations.  The balance of the Obligations
requiring the payment of money, if any, shall be payable by Borrower to Lender
as and when provided in this Agreement, the Other Agreements or the Security
Documents, or, if no date of payment is otherwise specified in the Loan
Documents,  on demand.

         3.3     Application of Payments and Collections.  All items of payment
received by Lender by 12:00 noon, Dallas, Texas time, on any Business Day shall
be deemed received on that Business Day.  All items of payment received after
12:00 noon, Dallas, Texas time, on any Business Day shall be deemed received on
the following Business Day.  Borrower irrevocably waives the right to direct
the application of any and all payments and collections at any time or times
hereafter received by Lender from or on behalf of Borrower, and Borrower does
hereby irrevocably agree that Lender shall have the continuing exclusive right
to apply and reapply any and all such payments and collections received at any
time or times hereafter by Lender or its agent against the Obligations, in such
manner as Lender may deem advisable, notwithstanding any entry by Lender upon
any of its books and records.  If as the result of  collections of Accounts as
authorized by Section 6.2.6 hereof a credit balance exists in the Loan Account,
such credit balance shall not accrue interest in favor of Borrower, but shall
be available to Borrower at any time or times for so long as no Default or
Event of Default exists.  Lender may, at its option, offset such credit balance
against any of the Obligations upon and after the occurrence of an Event of
Default.

         3.4     Loan Account.  Lender shall establish an account on its books
(the "Loan Account") and shall enter all Loans as debits to the Loan Account
and shall also record in the Loan Account all payments made by Borrower on any
Obligations and all proceeds of Collateral which are finally paid to Lender,
and may record therein, in accordance with customary accounting practice, other
debits and credits, including interest and all charges and expenses properly
chargeable to Borrower.

         3.5     Statements of Account.  Lender will account to Borrower
monthly with a statement of Loans, charges and payments made pursuant to this
Agreement supported, if requested by Borrower, by appropriate documentation,
and such account rendered by Lender shall be deemed final, binding and
conclusive upon Borrower unless Lender is notified by Borrower in writing to
the contrary within sixty (60) days after the date each accounting is deemed to
have been sent pursuant to Section 11.8 hereof.  Such notice shall only be
deemed an objection to those items specifically objected to therein.

SECTION 4.       TERM AND TERMINATION

         4.1     Term of Agreement.  Subject to Section 4.2 hereof and Lender's

                 4.2.2    Termination by Borrower.  Upon at least sixty (60)
days prior written notice to Lender, Borrower may, at its option, terminate
this Agreement; provided, however, no such termination shall be effective until

excess of $350,000 become ineligible because they fall within one of the
specified categories of ineligibility set forth in the definition of Eligible
Accounts or otherwise established by Lender, Drilling LP shall notify Lender of
such occurrence on the first Business Day following the day such occurrence
becomes known to Drilling LP and the Borrowing Base shall thereupon be adjusted
to reflect such occurrence.  If requested by Lender, Drilling LP shall execute
and deliver to Lender agings and formal written assignments of all of the
Accounts weekly or daily, which shall include all Accounts that have been
created since the date of the last assignment, together with copies of invoices

                 6.2.2    Discounts, Allowances, Disputes.  If Drilling LP
grants any discounts, allowances or credits that are not shown on the face of
the invoice for the Account involved, Drilling LP shall report such discounts,
allowances or credits, as the case may be, to Lender as part of the next

adjust all disputes and claims directly with the Account Debtor and to
compromise the amount or extend the time for payment of the Accounts upon such
terms and conditions as

payable to any governmental taxing authority, Lender is authorized, in its sole
discretion, to pay the amount thereof to the proper taxing authority for the
account of Drilling LP and to charge Borrower therefor; provided, however, that
Lender shall not be liable for any such taxes to any governmental taxing
authority that may be due by Drilling LP or Borrower.

                 6.2.4    Account Verification.  Whether or not a Default or an
Event of Default has occurred, any of Lender's officers, employees or agents
shall have the right, at any time or times hereafter, in the name of Lender,
any designee of Lender, Borrower or Drilling LP, to verify the validity, amount
or any other matter relating to any Accounts by mail, telephone, facsimile
transmission or otherwise.  Borrower and Drilling LP shall cooperate fully with
Lender in an effort to facilitate and promptly conclude any such verification
process.

                 6.2.5    Maintenance of Dominion Account. Drilling LP shall
maintain a Dominion Account pursuant to a lockbox arrangement acceptable to
Lender with such banks as may be selected by Drilling LP and be acceptable to
Lender.  Drilling LP shall issue to any such banks an irrevocable letter of
instruction directing such banks to deposit all payments or other remittances
received in the lockbox to the Dominion Account for application on account of
the Obligations.  All funds deposited in the Dominion Account shall immediately
become the property of Lender and Drilling LP shall obtain the agreement by
such banks in favor of Lender to waive any offset rights against the funds so
deposited.

                 6.2.6    Collection of Accounts, Proceeds of Collateral.  To
expedite collection, Drilling LP shall endeavor in the first instance to make
collection of the Accounts for Lender.  All remittances received by Borrower
and/or Drilling LP in respect of the Accounts, together with the proceeds of
any other Collateral, shall be held as Lender's property by Borrower or
Drilling LP, as the case may be, as trustee of an express trust for Lender's
benefit and Borrower or Drilling LP, as the case may be, shall immediately
deposit, or cause to be deposited, same in kind in the Dominion Account. Lender
retains the right at all times after the occurrence of an Event of Default to
notify Account Debtors (and account debtors of Borrower with respect to
Borrower's accounts) that Accounts, or accounts, the case may be, have been
assigned to Lender and to collect Accounts, or accounts, as the case may be,
directly in its own name and to charge the collection costs and expenses,

change in the condition, financial or otherwise, of Borrower or its
Subsidiaries and since such date there has been no material and adverse change
in the aggregate value of Drilling Rigs and real Property owned by Borrower,
except changes in the ordinary course of business, none of which individually
or in the aggregate has been materially adverse, and the corporate
restructuring of Borrower and its Subsidiaries occurring immediately prior to
the Amendment Date.  The fiscal year of each Borrower and each of its
respective Subsidiaries ends on December 31 of each year.

                 7.1.10   Full Disclosure.  The financial statements referred
to in Section 7.1.9 hereof do not, nor does this Agreement or any other written
statement of Borrower or any Loan Party to Lender, contain any untrue statement
of a material fact or omit a material fact, in either case known to Borrower,
necessary to make the statements contained therein or herein not misleading in
light of the circumstances under which such statement was made.  There is no
fact or circumstance known to Borrower which Borrower or its Subsidiaries has
failed to disclose to Lender in writing which could reasonably be expected to
have a Material Adverse Effect.

                 7.1.11.  Intentionally Omitted.

                 7.1.12.  Intentionally Omitted.

tax returns and other reports it is required by law to file and has paid, or
made provision for the payment of, all Taxes upon it, its income and Properties
as and when such Taxes are due and payable, except to the extent being Properly

Subsidiaries are adequate for all years not closed by applicable statutes, and
for its current fiscal year.

                 7.1.14.  Intentionally Omitted.

                 7.1.15.  Patents, Trademarks, Copyrights and Licenses.
Borrower and each of its Subsidiaries own or possess all the material patents,
trademarks, service marks, trade names, copyrights and licenses necessary for
the present and planned future conduct of their business without any material
conflict with the rights of others and the failure to have such ownership or
possession would result in a Material Adverse Effect.  All patents, trademarks,
service marks, trade names, copyrights, licenses and other similar rights are
listed on Exhibit F hereto.

                 7.1.16.  Governmental Consents.  Borrower and each of its
Subsidiaries have, and are in good standing with respect to, the failure of

business as heretofore or proposed to be conducted by them and to own or lease
and operate their Properties as now owned or leased by them.

Subsidiaries have duly complied with, and their Properties, business operations
and leaseholds are in compliance in all material respects with, the provisions
of all material Applicable Law and there have been no citations, notices or
orders of material noncompliance issued to Borrower or any of its Subsidiaries
under any such law, rule or regulation the failure to comply with which would
result in a Material Adverse Effect. Borrower and each of its Subsidiaries has
established and maintains an adequate monitoring system to insure that it
remains in compliance with all federal, state and local laws, rules and
regulations applicable to it.

                 7.1.18.  Restrictions.  Neither Borrower nor any of its
Subsidiaries is a party or subject to any contract, agreement, or charter or
other corporate restriction, which has or could be reasonably expected to have
a Material Adverse Effect.  Except as set forth on Exhibit G, neither Borrower
nor any of its Subsidiaries is a party or otherwise subject to any contract or
agreement which restricts the right or ability of Borrower or such
Subsidiaries, as the case may be, to incur Indebtedness upon terms which are
more restrictive than the terms of this Agreement.  No contracts or agreements
to which Borrower or any of its Subsidiaries is a party or by which any of
their respective properties are bound prohibits the execution of or compliance

knowledge of Borrower, threatened, against or affecting Borrower or any of its
Subsidiaries, or the business, operations, Properties, prospects, profits or
condition of Borrower or any of its Subsidiaries in which the amount in
controversy exceeds $1,000,000.  Neither Borrower nor any of its Subsidiaries
is in default with respect to any order, writ, injunction, judgment, decree or
rule of any court, governmental authority or arbitration board or tribunal.

                 7.1.20.  No Defaults.  No event has occurred and no condition
exists which would, upon or after the execution and delivery of this Agreement
or any Borrower's or its Subsidiaries' performance hereunder, constitute a
Default or an Event of Default that may reasonably be expected to result in
costs to Borrower in excess of $1,000,000.  Neither Borrower nor any of its
Subsidiaries is in default, and no event has occurred and no condition exists
which constitutes, or which with the passage of time or the giving of notice or
both would constitute, a default in the payment of any Indebtedness to any
Person for Money Borrowed that may reasonably be expected to result in costs to
Borrower in excess of $1,000,000.

                 7.1.21.  Intentionally Omitted.

                 7.1.22.  Pension Plans.  Except as disclosed on Exhibit K
hereto, neither Borrower nor any of its Subsidiaries has any Plan.  Borrower
and each of its Subsidiaries is in full compliance with the requirements of
ERISA and the regulations promulgated thereunder with respect to each Plan.  No
fact or situation that could result in a material adverse change in the
financial condition of Borrower or any of its Subsidiaries exists in connection
with any Plan.  Neither Borrower nor any of its Subsidiaries has any withdrawal
liability in connection with a Multiemployer Plan.

                 7.1.23.  Trade Relations.  There exists no actual or
threatened termination, cancellation or limitation of, or any adverse
modification or change in, the business relationship between Borrower or any of
its Subsidiaries and any customer or any group of customers whose purchases
individually or in the aggregate are material to the business of Borrower or
any of its Subsidiaries, or with any material supplier, and there exists no
condition or state of facts or circumstances which would materially adversely
affect any Borrower and its Subsidiaries taken as a whole or prevent Borrower
and its Subsidiaries from conducting such business after the consummation of
the transaction contemplated by this Agreement in substantially the same manner
in which it has heretofore been conducted.

                 7.1.24.  Labor Relations.  Except as described on Exhibit L
hereto, neither Borrower nor any of its Subsidiaries is a party to any
collective bargaining agreement.  There are no material grievances, disputes or
controversies with any union or any other organization of Borrower's or any of
its Subsidiaries' employees, or threats of strikes, work stoppages or any
asserted pending demands for collective bargaining by any union or organization
which could result in a Material Adverse Effect.

         7.2.    Survival of Representations and Warranties.  All
representations and warranties of Borrower, Drilling LP, and the other
Subsidiaries contained in this Agreement or any of the other Loan Documents
shall survive the execution, delivery and acceptance thereof by Lender and the
parties thereto and the closing of the transactions described therein or
related thereto.

held by the Borrower, a Guarantor or a Wholly Owned Subsidiary, so long as any
transfer of such Indebtedness or Preferred Stock to a Person other than the

the assumption by such Subsidiary of Indebtedness of another Subsidiary in
connection with a merger of such Subsidiaries, provided that no Subsidiary or
any successor (by way of merger) thereto existing on the Amendment Date shall
assume or otherwise become responsible for any indebtedness of an entity which

transaction or series of related transactions is in the ordinary course of and
pursuant to the reasonable requirements of Borrower's or such Subsidiary's
business and upon fair and reasonable terms at the time entered into which are
fully disclosed to Lender and are no less favorable than would be obtained in a
comparable arm's length transaction with a Person not an Affiliate or
stockholder of Borrower or such Subsidiary and (ii) (a) with respect to a

a transaction or series of related transactions that has a Fair Market Value
equal to or in excess of





                                       24

$10 million, the transaction or series of related transactions is approved by a
majority of the Board of Directors of the Borrower (including a majority of the
disinterested directors), which approval is set forth in a Board Resolution

dividends, repayments of loans or advances or other transfers of Property made
to such Joint Venture or foreign Subsidiary (but only to the extent such
interest, dividends, repayments or other transfers of Property are not included
in the calculation of Consolidated Net Income); Restricted Payments permitted
to be made as described in the first sentence of this paragraph will be
excluded in calculating the amount of Restricted Payments thereafter, except
that any such Restricted Payments permitted to be made pursuant to clauses (A),
(D), (E) (but only to the extent paid to someone other than the Borrower or any
of its





                                       27

of Restricted Payments thereafter.

                          For purposes of this covenant, if a particular

assets, then such Restricted Payment shall be deemed to be an amount equal to
the cash portion of such Restricted Payment, if any, plus an amount equal to
the Fair Market Value of such non-cash portion of such Restricted Payment.

whether by a single transaction or by a series of transactions (related or not)
except (i) dispositions permitted under Section 6.4.2, or (ii) (a) (except for

Fair Market Value of the Property; (b) at least 75% of such consideration
consists of Cash Proceeds (or the assumption of Indebtedness of the Borrower or

subject of such Asset Sale and the unconditional release of the Borrower or
such Subsidiary from such Indebtedness); and (c) the Borrower delivers to
Lender an Officers' Certificate certifying that such Asset Sale complies with
clauses (a) and (b) provided, however that any Asset Sale pursuant to a
condemnation, appropriation or other similar taking, including by deed in lieu
of condemnation, or pursuant to the foreclosure or other enforcement of a
Permitted Lien or exercise by the related lienholder of rights with respect
thereto, including by deed or assignment in lieu of foreclosure shall not be
required to satisfy the conditions set forth in clauses (a) and (b) of this
sentence.

Borrower covenants that, unless otherwise consented to by Lender in writing, it

processing thereof, at public or private sale or sales, with such notice as may
be required by law, in lots or in bulk, for cash or on credit, all as Lender,
in its sole discretion, may deem advisable.  Borrower agrees that any
requirement of notice to Borrower of any proposed public or private sale or
other disposition of Collateral by Lender shall be deemed reasonable notice
thereof if given at least ten (10) days prior thereto, and any such sale may be
held at such locations as Lender may designate in said notice.  Lender shall
have the right to conduct such sales on Borrower's premises, without charge
therefor, and such sales may be adjourned from time to time in accordance with
Applicable Law.  Lender shall have the right to sell, lease or otherwise
dispose of the Collateral, or any part thereof, for cash, credit or any
combination thereof, and Lender may purchase all or any part of the Collateral
at public or, if permitted by law, private sale and, in lieu of actual payment
of such purchase price, may set off the amount of such price against the
Obligations.  The proceeds realized from the sale of any Collateral may be
applied, after allowing two (2) Business Days for collection, first to the
costs, expenses and attorneys' fees incurred by Lender in collecting the
Obligations, in enforcing the rights of Lender under the Loan Documents and in
collecting, retaking, completing, protecting, removing, storing, advertising
for sale, selling and delivering any Collateral; second to the interest due
upon any of the Obligations; and third, to the principal of the Obligations.
If any deficiency shall arise, Borrower shall remain liable to Lender therefor.

                 10.3.4   The right to exercise all of Lender's rights and
remedies under any mortgage/deed of trust with respect to any real Property
forming a part of the Collateral.

                 10.3.5   Lender is hereby granted a license or other right to
use, without charge, Borrower's labels, patents, copyrights, rights of use of
any name, trade secrets, trade names, trademarks and advertising matter, or any
Property of a similar nature, as it pertains to the Collateral, in advertising
for sale and selling any Collateral and Borrower's rights under all licenses
and all franchise agreements shall inure to Lender's benefit.

                 10.3.6   Lender may, at its option, require Borrower to
deposit with Lender funds equal to the LC Amount and, if Borrower fails to
promptly make such deposit, Lender may advance such amount as a Revolving
Credit Loan (whether or not an Out of Formula Condition is created thereby).
Any such deposit or advance shall be held by Lender as a reserve to fund future
payments on such LC Guaranties and future drawings against such Letters of
Credit.  At such time as all LC Guaranties have been paid or terminated and all
Letters of Credit have been drawn upon or expired, any amounts remaining in
such reserve shall be applied against any outstanding Obligations, or, if all
Obligations have been indefeasibly paid in full, returned to Borrower.

         10.4    Remedies Cumulative; No Waiver.  All covenants, conditions,
provisions, warranties, guaranties, indemnities, and other undertakings of
Borrower contained in this Agreement and the other Loan Documents, or in any
document referred to herein or contained in any agreement supplementary hereto
or in any schedule or in any Guaranty Agreement given to Lender or contained in
any other agreement between Lender and Borrower, heretofore, concurrently, or
hereafter entered into, shall be deemed cumulative to and not in derogation or
substitution of any of the terms, covenants, conditions, or agreements of
Borrower herein contained.  The failure or delay of Lender to require strict
performance by Borrower of any provision of this Agreement or to exercise or
enforce any rights, Liens, powers, or remedies hereunder or under any of the
aforesaid agreements or other documents or security or Collateral shall not
operate as a waiver of such performance, Liens, rights, powers and  remedies,
but all such requirements, Liens, rights, powers, and remedies shall continue
in full force and effect until all Loans and all other Obligations owing or to
become owing from Borrower to Lender shall have been fully satisfied.  None of
the undertakings, agreements, warranties, covenants and representations of
Borrower contained in this Agreement or any of the other Loan Documents and no
Event of Default by Borrower under this Agreement or any other Loan Documents
shall be deemed to have been suspended or waived by Lender, unless such
suspension or waiver is by an instrument in writing specifying such suspension
or waiver and is signed by a duly authorized representative of Lender and
directed to Borrower.

SECTION 11.      MISCELLANEOUS

         11.1    Power of Attorney.  Borrower hereby irrevocably designates,
makes, constitutes and appoints Lender (and all Persons designated by Lender)
as Borrower's true and lawful attorney (and agent-in-fact) and Lender, or
Lender's agent, may, without notice to Borrower and in either Borrower's or
Lender's name, but at the cost and expense of Borrower:

                 11.1.1   At such time or times as Lender or said agent, in its
sole discretion, may determine, endorse Borrower's name on any checks, notes,

control.

                 11.1.2   At such time or times upon the occurrence and during

in any manner, of any item of payment or proceeds relating to any Collateral;

the name of Borrower upon any of the items of payment or proceeds relating to
any Collateral and deposit the same to the account of Lender on account of the
Obligations; (viii) endorse the name of Borrower upon any chattel paper,

obligations under this Agreement.

         11.2    Indemnity.  BORROWER HEREBY INDEMNIFIES, HOLDS HARMLESS, AND
SHALL DEFEND LENDER AND ITS DIRECTORS, OFFICERS, AGENTS, COUNSEL AND EMPLOYEES
("INDEMNIFIED PERSONS") FROM AND AGAINST ANY AND ALL LOSSES, LIABILITIES,
DAMAGES, COSTS, EXPENSES, SUITS, ACTIONS AND PROCEEDINGS ("LOSSES") EVER
SUFFERED OR INCURRED BY ANY INDEMNIFIED PERSON ARISING OUT OF OR RELATING TO
THIS AGREEMENT OR ANY OTHER TRANSACTION CONTEMPLATED HEREBY, INCLUDING, WITHOUT
LIMITATION, ANY LOSSES CAUSED BY THE NEGLIGENCE OF ANY SUCH INDEMNIFIED PERSON,
BUT NOT INCLUDING ANY LOSSES CAUSED BY THE GROSS NEGLIGENCE OR WILLFUL
MISCONDUCT OF ANY SUCH INDEMNIFIED PERSON, AND BORROWER SHALL REIMBURSE LENDER
AND EACH OTHER INDEMNIFIED PERSON FOR ANY EXPENSES (INCLUDING IN CONNECTION
WITH THE INVESTIGATION OF, PREPARATION FOR OR DEFENSE OF ANY ACTUAL OR
THREATENED CLAIM, ACTION OR PROCEEDING ARISING THEREFROM, INCLUDING ANY SUCH
COSTS OF RESPONDING TO DISCOVERY REQUESTS OR SUBPOENAS, REGARDLESS OF WHETHER
LENDER OR SUCH OTHER INDEMNIFIED PERSON IS A PARTY THERETO).  WITHOUT LIMITING
THE GENERALITY OF THE FOREGOING, THIS INDEMNITY SHALL EXTEND TO ANY CLAIMS
ASSERTED AGAINST LENDER OR ANY OTHER INDEMNIFIED PERSON BY ANY PERSON UNDER ANY
ENVIRONMENTAL LAWS OR SIMILAR LAWS BY REASON OF BORROWER'S OR ANY OTHER
PERSON'S FAILURE TO COMPLY WITH LAWS APPLICABLE TO SOLID OR HAZARDOUS WASTE
MATERIALS OR OTHER TOXIC SUBSTANCES.  BORROWER MAY SELECT COUNSEL WITH RESPECT
TO ANY LOSSES; PROVIDED, HOWEVER, EACH INDEMNIFIED PERSON SHALL HAVE THE RIGHT
TO MONITOR THE PROGRESS OF ANY CLAIMS, SUITS AND ADMINISTRATIVE PROCEEDINGS
DEFENDED BY BORROWER HEREUNDER WITH COUNSEL OF SUCH INDEMNIFIED PERSON'S
CHOICE, OR CONDUCT ITS DEFENSE THROUGH COUNSEL OF SUCH INDEMNIFIED PERSON'S
CHOICE, IN THE EVENT THAT (I) SUCH INDEMNIFIED PERSON DETERMINES IN GOOD FAITH
THAT THE CONDUCT OF ITS DEFENSE BY BORROWER COULD BE MATERIALLY PREJUDICIAL TO
SUCH INDEMNIFIED PERSON'S INTERESTS OR THAT OTHER REASONABLE GROUNDS EXIST
WHICH DEMONSTRATE A LACK OF EFFECTIVENESS OR HIGH LEVEL OF QUALITY IN THE





                                       36
<PAGE>   42
CONDUCT OF SUCH DEFENSE BY BORROWER, AND (II) PRIOR TO RETAINING SUCH COUNSEL
FOR SUCH PURPOSE, SUCH INDEMNIFIED PERSON SHALL CONSULT WITH BORROWER AND SHALL
ATTEMPT IN GOOD FAITH TO AGREE UPON COUNSEL TO CONDUCT THE DEFENSE ON BEHALF OF
BORROWER AND SUCH INDEMNIFIED PERSON, AND IN EACH CASE THE FEES AND
DISBURSEMENTS OF SUCH COUNSEL SHALL BE PAID BY BORROWER; PROVIDED, HOWEVER,
THAT IF SUCH MUTUAL AGREEMENT IS NOT REACHED WITHIN A REASONABLE TIME ON
SELECTING COUNSEL, THEN SUCH INDEMNIFIED PERSON MAY RETAIN ITS OWN COUNSEL AT
BORROWER'S EXPENSE.  NOTWITHSTANDING ANY CONTRARY PROVISION OF THIS AGREEMENT,
THE OBLIGATION OF BORROWER UNDER THIS SECTION 11.2 SHALL SURVIVE THE PAYMENT IN
FULL OF THE OBLIGATIONS AND THE TERMINATION OF THIS AGREEMENT.

         11.3    Modification of Agreement; Sale of Interest.  This Agreement
may not be modified, altered or amended, except by an agreement in writing
signed by Borrower and Lender.  Borrower may not sell, assign or transfer any
interest in this Agreement, any of the other Loan Documents, or any of the
Obligations, or any portion thereof, including Borrower's rights, title,
interests, remedies, powers, and duties hereunder or thereunder.  Borrower
hereby consents to Lender's participation, sale, assignment, transfer or other
disposition, at any time or times hereafter, of this Agreement and any of the
other Loan Documents, or of any portion hereof or thereof, including Lender's
rights, title, interests, remedies, powers, and duties hereunder or thereunder
to any Affiliate of Lender or any Person that purchases all or substantially
all of the assets of Lender.  Any other participation, sale, assignment,
transfer or other disposition, at any time or times hereafter, of this
Agreement and any of the other Loan Documents shall be subject to Borrower's
prior consent, such consent not to be unreasonably withheld.  If Lender
requests such consent in writing and Borrower does not respond in writing
within five (5) Business Days from the date of delivery of such request, the
consent of Borrower shall be deemed to have been given.  In the case of an
assignment, the assignee shall have, to the extent of such assignment, the same
rights, benefits and obligations as it would if it were "Lender" hereunder and
Lender shall be relieved of all obligations hereunder upon any such assignment.
Borrower agrees that it will use its best efforts to assist and cooperate with
Lender in any manner reasonably requested by Lender to effect the sale of
participations in or assignments of any of the Loan Documents or any portion
thereof or interest therein, including assisting in the preparation of
appropriate disclosure documents.  Borrower further agrees that Lender may
disclose credit information regarding Borrower and its Subsidiaries to any
potential Participant or assignee.

         11.4    Severability.  Wherever possible, each provision of this
Agreement shall be interpreted in such manner as to be effective and valid
under Applicable Law, but if any provision of this Agreement shall be
prohibited by or invalid under Applicable Law, such provision shall be
ineffective only to the extent of such prohibition or invalidity, without
invalidating the remainder of such provision or the remaining provisions of
this Agreement.

         11.5    Successors and Assigns.  This Agreement, the Other Agreements
and the Security Documents shall be binding upon and inure to the benefit of
the successors and assigns of Borrower and Lender permitted under Section 11.3
hereof.

         11.6    Cumulative Effect; Conflict of Terms.  The provisions of the
Other Agreements and the Security Documents are hereby made cumulative with the
provisions of this Agreement.  Except as otherwise provided in Section 3.2
hereof and except as otherwise provided in any of the other Loan Documents by
specific reference to the applicable provision of this Agreement, if any
provision contained in this Agreement is in direct conflict with, or
inconsistent with, any provision in any of the other Loan Documents, the
provision contained in this Agreement shall govern and control.

         11.7    Execution in Counterparts.  This Agreement may be executed in
any number of counterparts and by different parties hereto in separate
counterparts, each of which when so executed and delivered shall be deemed to
be an original and all of which counterparts taken together shall constitute
but one and the same instrument.

hereto shall be in writing and shall be sent by certified or registered mail,

TAKING OF ANY ACTION UNDER THIS AGREEMENT TO ENFORCE SAME IN ANY OTHER

         the Account in freely convertible Dollars at a place of payment within
         the United States; (vii) it arises from a sale to the Account Debtor
         on a bill-and-hold, guaranteed sale, sale-or-return, sale-on-approval,

         Account Debtor has relocated to New Jersey, Minnesota, Indiana, West
         Virginia or any other state imposing similar conditions on the right
         of a creditor to collect accounts receivable unless Drilling LP has

         represent a final sale; (xi) the Account is evidenced by chattel paper
         or an instrument of any kind, or has been reduced to judgment; (xii)
         Drilling LP has made any agreement with the Account Debtor for any
         deduction therefrom, except for discounts or allowances which are made
         in the ordinary course of business for prompt payment and which
