Explanatory Note

     Parker Drilling Company (the “Company”) hereby amends Items 1 and 2 of Part I and Item 6 of Part II of its Quarterly Report on Form 10-Q for the period ended March 31, 2007, as originally filed on May 10, 2007 (the “March 2007 Form 10-Q”), solely to revise U.S. and international drilling operating expenses, total drilling and rental operating expenses, drilling and rental operating income and general and administrative expenses for the three months ended March 31, 2006, so as to conform those amounts in this Form 10-Q/A to the amounts previously reported on the Company’s Consolidated Condensed Statements of Operations for the quarter ended March 31, 2006 included in the Form 10-Q filed on May 9, 2006. Corresponding changes have been made to Note 4 to the Company’s Consolidated Condensed Statements of Operations in Item 1 of Part I and under “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Results of Operations” in Item 2 of Part I. There were no changes to revenues, operating income, net income or earnings per share for the three months ended March 31, 2006. There were no changes to any amounts for the three months ended March 31, 2007.

     In the first quarter of 2007, the Company revised its overhead allocations to include allocation of some overhead department expenses that had previously been classified as corporate general and administrative expenses. In the original March 31, 2007 Form 10-Q, the Company had adjusted its presentation of the items described above for 2006 as well as 2007. The Company has determined that, as a change in estimate, the change should be applied prospectively only and that prior period amounts should not be reclassified as a result of the change. Accordingly, the Company has filed this Form 10-Q/A.

     For purposes of this Form 10-Q/A, and in accordance with Rule 12b-15 under the Securities Exchange Act of 1934, as amended, each item of the Form 10-Q that was affected by the restatement described above has been amended to the extent affected and restated in its entirety. No attempt has been made in this Form 10-Q/A to update other disclosures as presented in the Form 10-Q except as required to reflect the effects of the restatement described above. Accordingly, this Form 10-Q/A should be read in conjunction with the Company’s SEC filings made subsequent to the filing of the Form 10-Q, including any amendments of those filings. In addition, this Form 10-Q/A includes updated certifications from the Company’s CEO and CFO as Exhibits 31.1, 31.2, 32.1 and 32.2.

PARKER DRILLING COMPANY AND SUBSIDIARIES

NOTES TO THE UNAUDITED CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

1.	General — In the opinion of the management of Parker Drilling Company, the accompanying unaudited consolidated condensed financial statements reflect all adjustments (of a normally recurring nature) which are necessary for a fair presentation of (1) the financial position as of March 31, 2007 and December 31, 2006, (2) the results of operations for the three months ended March 31, 2007 and 2006, and (3) cash flows for the three months ended March 31, 2007 and 2006. Results for the three months ended March 31, 2007 are not necessarily indicative of the results that will be realized for the year ending December 31, 2007. The financial statements should be read in conjunction with our Form 10-K for the year ended December 31, 2006.
	Stock-Based Compensation —Total stock-based compensation expense recognized under SFAS No. 123R for the three months ended March 31, 2007 and 2006, was $1.8 million and $1.2 million respectively, of which $1.8 million and $1.1 million, respectively, was related to restricted stock plan expense. Stock-based compensation expense is included in our consolidated condensed income statement in “General and administration expense.” Unvested stock options at December 31, 2006 and March 31, 2007 were 8,334 and zero, respectively. Total unrecognized compensation cost related to stock options granted under our plans was approximately $1,200 at December 31, 2006 and zero at March 31, 2007. The Company had 3,238,800 outstanding and exercisable stock options as of March 31, 2007, the aggregate intrinsic value of which was $4.2 million, with a weighted average exercise price of $7.57. Unvested restricted stock awards at December 31, 2006 and March 31, 2007 were 1,556,485 shares and 2,167,498 shares, respectively. Total unrecognized compensation cost related to unamortized restricted stock awards was $4.8 million as of December 31, 2006 and $10.1 million as of March 31, 2007. There were 793,845 restricted shares granted (net of forfeitures) to certain officers and key employees during the three months ended March 31, 2007. The remaining unrecognized compensation cost related to unamortized restricted stock awards will be amortized over a weighted-average vesting period of approximately one year.
	During the three months ended March 31, 2006 the valuation assumptions used in our Black-Scholes option pricing model to estimate the fair value of stock options granted were 16.9 percent for expected volatility, .25 years expected term, 4.23 percent risk free interest rate and there was no expected dividend yield. There were no stock options granted in the first quarter of 2007.
	The tax benefit realized for the tax deductions from restricted stock vesting totaled $140,000 for the three months ended March 31, 2007, which has been reported as a financing cash inflow in the consolidated condensed statement of cash flows. No options were exercised for the three months ended March 31, 2007.
2.	Common Stock Offering – In January 2006, we issued 8,900,000 shares of common stock pursuant to a Free Writing Prospectus dated January 17, 2006 and a Prospectus Supplement dated January 18, 2006. On January 23, 2006, we realized $11.23 per share or a total of $99.9 million of net proceeds before expenses, but after underwriter discount, from the offering.

Options to purchase 524,000 shares of common stock with exercise prices ranging from $10.81 to $12.19 per share were outstanding during the three months ended March 31, 2006, but were not included in the computation of diluted EPS because the options’ exercise prices were greater than the average market price of the common shares.

4. Business Segments – The primary services we provide are as follows: U.S. drilling, international drilling and rental tools. Information regarding our operations by industry segment for the three months ended March 31, 2007 and 2006 is as follows:

5.	Disposition of Assets – During the first quarter of 2007 we sold workover barge Rigs 9 and 26 for proceeds of approximately $20.5 million resulting in a recognized gain of $15.1 million. These two rigs were classified as assets held for sale as of December 31, 2006.
6.	Accounting for Uncertainty in Income Taxes – In June 2006, the FASB issued Interpretation No. 48, “Accounting for Uncertainty in Income Taxes, an interpretation of FASB Statement 109” (“FIN 48”). This accounting statement prescribes financial statement recognition threshold and measurement criteria for tax positions taken or expected to be taken in tax returns.
	The Company adopted FIN 48 effective January 1, 2007. As a result, the Company has increased its liability by $54.5 million for unrecognized tax amounts related to various federal, state and international tax matters. Included in this amount is $35.1 million of tax positions, that, if recognized, would have impacted the Company’s effective tax rate. The recognition of this liability is required under FIN 48 because of the uncertainty regarding the ultimate outcome of certain tax positions. Although the Company’s position regarding the ultimate outcome of these matters is unchanged, the Company is now required to record a liability at a lower threshold across the Company’s worldwide operations. The Company has accounted for the entire $54.5 million as a reduction to the January 1, 2007 balance of retained earnings.
	Of the $54.5 million referred to above, $49 million is related to Kazakhstan. For a complete overview of this issue, see Kazakhstan Tax Claims in Note 10.

NOTES TO THE UNAUDITED CONSOLIDATED CONDENSED FINANCIAL STATEMENTS (continued)

	Accounting for Uncertainty in Income Taxes (continued)
	The Company has classified currency fluctuations, interest and penalties as a component of tax expense. On January 1, 2007, we recorded approximately $41.3 million for interest and penalties related to uncertain tax positions. During the three months ended March 31, 2007, the Company recognized an additional liability of approximately $1.9 million, comprising of currency fluctuations, interest and a release of a previously recognized liability. The Company does not expect that the unrecognized tax amounts will change significantly within the next twelve months.
	The Company conducts business globally and, as a result, the Company or one or more of its subsidiaries files income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions. In the normal course of business our returns are subject to examination by taxing authorities throughout the world.
7.	Income Tax Expense – Income tax expense was $24.1 million for the first quarter of 2007, as compared to income tax expense of $14.5 million for the first quarter of 2006. The $9.6 million increase in taxes was due primarily to the impact of the gain recognized upon the sale of the two workover barge rigs, the inclusion of FIN 48 (described in Note 6) and the increase in operating income primarily from U.S. operations.
8.	Long-Term Debt

Our current $40.0 million credit facility is available for general corporate purposes and to fund reimbursement obligations under letters of credit the banks issue on our behalf pursuant to this facility. Availability under the revolving credit facility is subject to a borrowing base limitation based on 85 percent of eligible receivables plus a value for eligible rental tools equipment. The credit facility calls for a borrowing base calculation only when the credit facility has outstanding loans, including letters of credit, totaling at least $25.0 million. As of March 31, 2007, there were $21.1 million in letters of credit outstanding and no loans. On March 1, 2006, an amendment was signed to eliminate the $25.0 million sub-limit for letters of credit and to give us the ability to prepay outstanding Senior Notes and Senior Floating Rate Notes without limitation concerning commitments under the credit facility.

9.

Derivative Instruments – We use derivative instruments to manage risks associated with interest rate fluctuations in connection with our $100.0 million Senior Floating Rate Notes. These derivative instruments, which consist of variable-to-fixed interest rate swaps, do not meet the hedge criteria in SFAS No. 133, “Accounting for Derivative Instruments and Hedging Activities,” and are therefore not designated as hedges. Accordingly, the change in the fair value of the interest rate swaps is recognized currently in earnings.

NOTES TO THE UNAUDITED CONSOLIDATED CONDENSED FINANCIAL STATEMENTS (continued)

Derivative Instruments (continued)

As of March 31, 2007, we had the following derivative instruments outstanding related to our interest rate swaps, which are included in “Other current assets” and “Other noncurrent assets” as determined by their termination dates:

10.	Contingencies
	Kazakhstan Tax Claims
	On October 12, 2005, the Kazakhstan Branch (“PKD Kazakhstan”) of Parker Drilling Company International Limited (“PDCIL”) received an Act of Tax Audit from the Ministry of Finance of Kazakhstan (“MinFin”) assessing PKD Kazakhstan an amount of KZT (Kazakhstan Tenge) 14.9 billion (approximately $115.1 million). Approximately KZT 7.5 billion or $58.3 million was assessed for import Value Added Tax (“VAT”), administrative fines and interest on equipment imported to perform the drilling contracts (the “VAT Assessment”) and approximately KZT 7.4 billion or $56.8 million for corporate income tax, individual income tax and social tax, administrative fines and interest in connection with the reimbursements received from the client for the upgrade of barge Rig 257 and other issues (the “Income Tax Assessment”).
	The VAT and Income Tax Assessment were both appealed to the Astana City Court and on April 6, 2006, the Astana City Court issued an opinion in favor of PKD Kazakhstan on the Income Tax Assessment and in favor of MinFin on the VAT Assessment, but reduced the amount of the VAT Assessment. MinFin and PKD Kazakhstan both appealed the decision of the Astana City Court to the Civil Panel of the Supreme Court of Kazakhstan. On May 24, 2006, the Civil Panel of the Supreme Court issued a decision upholding the ruling of the Astana City Court on the VAT Assessment. Consistent with its contractual obligations, on November 20, 2006, the client advanced the actual amount of the VAT Assessment and this amount has been remitted to MinFin. The client has also contractually agreed to reimburse PKD Kazakhstan for any incremental income taxes that PKD Kazakhstan incurs from the reimbursement of this VAT Assessment
	Contrary to two previous rulings on this precise issue, the May 24, 2006, ruling of the Civil Panel of the Supreme Court affirmed the Income Tax Assessment. PKD Kazakhstan immediately made application for a stay of execution of the ruling, based on the fact that the Supreme Court has decided this issue in favor of PKD Kazakhstan on two previous occasions and because the decision is inconsistent with the US-Kazakhstan tax treaty, and also requested that the five-member supervisory panel of the Supreme Court grant a supervisory review of the decision. On May 30, 2006, the Supreme Court granted a stay of execution of the decision pending a determination of the five-member panel of the Supreme Court whether or not to grant supervisory review of the decision.

10

NOTES TO THE UNAUDITED CONSOLIDATED CONDENSED FINANCIAL STATEMENTS (continued)

Contingencies (continued)

The Supreme Court repeatedly postponed a decision on the issue of supervisory review, which postponement was apparently granted to allow the Competent Authority from the U.S. and Kazakhstan to address this matter. Competent Authority review is a tax treaty procedure to resolve disputes as to which country may tax income covered under the treaty. In response to the petition initiated by PKD Kazakhstan and pursuant to the Mutual Agreement Procedures of the U.S.-Kazakhstan Tax Treaty, the Competent Authority of the U.S. IRS Treaty Division and MinFin held meetings in Astana, Kazakhstan, on March 21 and 22, 2007, to address the treaty issues. The respective Competent Authorities were unable to achieve mutual agreement as to which country may tax the income in issue under the tax treaty.

On April 12, 2007, the Supreme Court determined that the May 24, 2006, ruling of the Supreme Court should be reviewed by a five member supervisory panel of the Supreme Court because there was doubt as to the lawfulness and validity of the May 24, 2006 ruling. In its ruling sending the case to the supervisory panel, the Supreme Court cited examples of how the May 24, 2006, ruling had wrongfully applied certain provisions of the Kazakhstan Tax Code, had relied upon irrelevant evidence and had not taken into account the double taxation provisions of the US-Kazakhstan Tax Treaty. Based on previous rulings of the Supreme Court in favor of PKD Kazakhstan, the recent ruling subjecting the latest Supreme Court decision to supervisory review and the provisions of the tax treaty, the Company has a substantial basis to believe the May 24, 2006, decision will not be upheld.

The accounting treatment of this pending tax matter under the new FIN 48 interpretation is addressed in Note 6.

Bangladesh Claim

In September 2005, a subsidiary of the Company was served with a lawsuit filed in the 152nd District Court of Harris County State of Texas on behalf of numerous citizens of Bangladesh claiming $250 million in damages due to various types of property damage and personal injuries (none involving loss of life) arising as a result of two blowouts that occurred in Bangladesh in January and June 2005, although only the June 2005 blowout involved the Company. This case was dismissed against the subsidiary of the Company based on forum non conveniens, a legal defense raised by the subsidiary claiming that Houston, Texas, is not the appropriate location for this suit to be filed. The plaintiffs have appealed this dismissal; however the Company believes the plaintiffs’ prospects of being successful on appeal is remote.

Asbestos-Related Claims

In August 2004, the Company was notified that certain of its subsidiaries have been named, along with other defendants, in several complaints that have been filed in the Circuit Courts of the State of Mississippi by several hundred persons that allege that they were employed by some of the named defendants between approximately 1965 and 1986. The complaints name as defendants numerous other companies that are not affiliated with the Company, including companies that allegedly manufactured drilling related products containing asbestos that are the subject of the complaints.

The complaints allege that the Company’s subsidiaries and other drilling contractors used asbestos-containing products in offshore drilling operations, land-based drilling operations and in drilling structures, drilling rigs, vessels and other equipment and assert claims based on, among other things, negligence and strict liability and claims under the Jones Act and that the Plaintiffs are entitled to monetary damages. Based on the report of the special master, these complaints have been severed and venue of the claims transferred to the county in which the plaintiff resides or the county in which the cause of action allegedly accrued. Subsequent to the filing of amended complaints, Parker has joined with other co-defendants in filing motions to compel discovery to determine what plaintiffs have an employment relationship with which defendant, including whether or not any plaintiffs have an employment relationship with subsidiaries of the Company. Out of 528 amended single-plaintiff complaints filed to date, eleven plaintiffs have identified Parker Drilling or one of its affiliates as a defendant.

NOTES TO THE UNAUDITED CONSOLIDATED CONDENSED FINANCIAL STATEMENTS (continued)

	Contingencies (continued)
	The subsidiaries named in these asbestos-related lawsuits intend to defend themselves vigorously and, based on the information available to the Company at this time, the Company does not expect the outcome to have a material adverse effect on its financial condition, results of operations or cash flows; however, there can be no assurance as to the ultimate outcome of these lawsuits.
11.	Recent Accounting Pronouncements –
	In September 2006, the FASB issued SFAS No. 157, “Fair Value Measures” (SFAS 157). SFAS 157 defines fair value, establishes a framework for measuring fair value and enhances disclosures about fair value measures required under other accounting pronouncements, but does not change existing guidance as to whether or not an instrument is carried at fair value. SFAS 157 is effective for fiscal years beginning after November 15, 2007 (i.e., the beginning of the Company’s fiscal year 2008). The Company is currently evaluating the impact of SFAS 157 on its Consolidated Financial Statements.
	In February 2007, the FASB issued SFAS No. 159, The Fair Value Option for Financial Assets and Liabilities-Including an Amendment of FASB Statement No. 115 (SFAS No. 159). SFAS No. 159 allows certain financial assets and liabilities to be recognized, at the Company’s election, at fair market value, with any gains or losses for the period recorded in the statement of income. This gives a company the opportunity to mitigate volatility in reported earnings caused by measuring related assets and liabilities differently without having to apply complex hedge accounting provisions. The statement is effective for fiscal years beginning after November 15, 2007. The Company has not determined the impact on its Consolidated Financial Statements, if any, of the adoption of SFAS No. 159.

All statements contained in this Form 10-Q, other than statements of historical facts, are “forward-looking statements” for purposes of these provisions, including any statements regarding:

• stability of prices and demand for oil and natural gas;

• levels of oil and natural gas exploration and production activities;

• demand for contract drilling and drilling related services and demand for rental tools;

• our future operating results and profitability;

• our future rig utilization, dayrates and rental tools activity;

• entering into new, or extending existing, drilling contracts and our expectations concerning when our rigs will commence operations under such contracts;

• growth through acquisitions of companies or assets;

• capital expenditures for acquisition of rigs, construction of new rigs or major upgrades to existing rigs;

• entering into joint venture agreements with local companies;

• our future liquidity;

• availability and sources of funds to reduce our debt and expectations of when debt will be reduced;

     In some cases, you can identify these statements by forward-looking words such as “anticipate,” “believe,” “could,” “estimate,” “expect,” “intend,” “outlook,” “may,” “should,” “will” and “would” or similar words.

DISCLOSURE NOTE REGARDING FORWARD-LOOKING STATEMENTS (continued)

     Each “forward-looking statement” speaks only as of the date of this Form 10-Q, and we undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. Before you decide to invest in our securities, you should be aware that the occurrence of the events described in these risk factors and elsewhere in this Form 10-Q could have a material adverse effect on our business, results of operations, financial condition and cash flows.

OUTLOOK AND OVERVIEW

     Our U.S. drilling and rental tools operations continued their solid performance in the first quarter of 2007 providing significant earnings growth on higher operating margins. While demand was strong in the first quarter for our preferred barges in the U.S. Gulf of Mexico, current market forces have begun to soften U.S. barge dayrates. With regard to our international operations, new multi-year contracts for existing international land rigs at significantly higher dayrates and the commencement of operations of our four new 2,000 HP land rigs over the next few months should provide improved international results for the foreseeable future.

Overview

     Drilling and rental operating income in the first quarter of 2007 increased 21 percent over the first quarter of 2006, driven primarily by our U.S. operations. Average dayrates for our U.S. Gulf of Mexico barge rig operations increased by 52 percent over the first quarter of 2006 and our rental tools business contributed an additional 12 percent in operating income on a $2.7 million increase in revenues over the first quarter of 2006.

     International sector operations were in transition in the first quarter of 2007 as we had six rigs in various stages of mobilizing from inactive status to new contracts (three en route to Mexico, two to Kazakhstan’s Karachaganak Field and one to Libya). In the comparable quarter in 2006, we had a two-rig operation in Turkmenistan, six land rigs in Mexico and two rigs drilling under our Tengizchevroil (“TCO”) contract in Kazakhstan for most of the 2006 quarter, all of which completed their drilling programs in 2006. In addition, our Nigerian barge rigs were sold in August 2006.

     While five of the rigs that completed drilling programs in 2006 were already operating under new contracts with significantly higher dayrates in the first quarter of 2007 (two rigs that had been in Mexico were operating in Colombia and two in the U.S. land market, and one rig from our Turkmenistan operation was drilling in Kazakhstan), overall international operating income declined by $3.4 million as a result of lower utilization (69 percent in 2007 compared to 86 percent in 2006) and the sale of our Nigerian barge rigs.

Outlook

     In the U.S. Gulf of Mexico area, utilization is currently 65 percent down from an average utilization of 73 percent for the first quarter as three rigs undergo scheduled maintenance and equipment upgrades. We have seen a decline in the contract backlog, although we do expect to return to higher utilization levels later in 2007. In the immediate future, Rig 8, which has been undergoing refurbishment and upgrade since late 2006, will begin drilling on a nine-month term contract in mid-May. It is management’s view that the recent softening in the U.S. Gulf of Mexico is a reflection of the uncertainty in the U.S. gas market. Although this uncertainty has reduced rates from historic highs, we believe that there is sufficient demand to generate strong financial results from our domestic barge fleet through 2007.

     Throughout 2006 and into 2007 we have increased our focus on international markets. We have successfully entered into new contracts or renegotiated existing contracts at significantly higher dayrates for 13 of our existing international land rigs and one of our international offshore rigs.

     Five of the rigs have been operating under the higher market rates since the fourth quarter of 2006, one of which completed its first new contract (in the U.S.) and is currently moving to a new multi-year contract in Mexico.

20

OUTLOOK AND OVERVIEW (continued)

Outlook (continued)

     Another six rigs are coming off inactive status to new multi-year contracts and are expected to begin drilling in the second quarter or early in the third quarter. Two other rigs have newly negotiated rates that will begin after current contract wells are completed in late 2007 and early 2008.

     We have also made significant strides in the execution of our strategic growth plan as two of our four new 2,000 HP rigs have been delivered to Algeria, both of which should commence operations in the second quarter. The other two new rigs have entered into three-year contracts in Mexico, with construction finishing in the second quarter of 2007 and commencement of operations in the third quarter. In addition, five of six new rigs constructed under our joint venture in Saudi Arabia are currently rigging up and undergoing commissioning, with one rig commencing operations in April 2007.

     Our new Quail facility in Texarkana, Texas opened on April 2, 2007 and will enable us to increase coverage in the Barnett, Woodford and Fayetteville shale areas in Texas, Oklahoma and Arkansas markets, respectively. We expect improved results through 2007 with the addition of this location and our increased investment in rental equipment at all locations.

     At March 31, 2007 we had approximately $157.6 million in cash, cash equivalents and marketable securities. We have spent $53.0 million on capital expenditures through March 31, 2007. We have committed approximately $235 million for maintenance of our rig fleet and capital projects for 2007. The majority of our capital spending is project specific, including new rigs and expansion of Quail, and is consistent with our strategic growth plan. Capital expenditures will be funded through cash flows from operations and existing cash.

RESULTS OF OPERATIONS

Three Months Ended March 31, 2007 Compared with Three Months Ended March 31, 2006

     We recorded net income of $30.0 million for the three months ended March 31, 2007, as compared to net income of $11.5 million for the three months ended March 31, 2006. Drilling and rental operating income was $49.5 million for the three months ended March 31, 2007 as compared to $39.1 million for the three months ended March 31, 2006. Gain on disposition of assets for the current quarter was $16.4 million as compared to $0.4 million in the comparable quarter in 2006.

     The following is an analysis of our operating results for the comparable quarters:

	Three Months Ended March 31,
	2007					2006
	(Dollars in Thousands)
Drilling and rental revenues:
U.S. drilling	$	61,624		41	%	$	40,253		27	%
International drilling		59,674		39	%		79,830		54	%
Rental tools		29,975		20	%		27,251		19	%
Total drilling and rental revenues	$	151,273		100	%	$	147,334		100	%
Drilling and rental operating income:
U.S. drilling gross margin excluding depreciation and amortization (1)	$	34,863		57	%	$	22,783		57	%
International drilling gross margin excluding depreciation and amortization (1)		13,891		23	%		18,458		23	%
Rental tools gross margin excluding depreciation and amortization (1)		18,812		63	%		16,781		62	%
Depreciation and amortization		(18,059	)				(16,957	)
Total drilling and rental operating income (2)		49,507					41,065
General and administration expense		(5,888	)				(7,694	)
Gain on disposition of assets, net		16,404					448
Total operating income	$	60,023				$	33,819

(1) Drilling and rental gross margins, excluding depreciation and amortization, are computed as drilling and rental revenues less direct drilling and rental operating expenses, excluding depreciation and amortization expense; drilling and rental gross margin percentages are computed as drilling and rental gross margin excluding depreciation and amortization as a percent of drilling and rental revenues. The gross margin amounts excluding depreciation and amortization and gross margin percentages should not be used as a substitute for those amounts reported under accounting principles generally accepted in the United States (“GAAP”). However, we monitor our business segments based on several criteria, including drilling and rental gross margin. Management believes that this information is useful to our investors because it more accurately reflects cash generated by segment. Such gross margin amounts are reconciled to our most comparable GAAP measure as follows:

			International
	U.S. Drilling		Drilling		Rental Tools
	(Dollars in Thousands)
Three Months Ended March 31, 2007
Drilling and rental operating income (2)	$	27,474	$	8,260	$	13,773
Depreciation and amortization		7,389		5,631		5,039
Drilling and rental gross margin excluding depreciation and amortization	$	34,863	$	13,891	$	18,812
Three Months Ended March 31, 2006
Drilling and rental operating income (2)	$	17,726	$	11,153	$	12,186
Depreciation and amortization		5,057		7,305		4,595
Drilling and rental gross margin excluding depreciation and amortization	$	22,783	$	18,458	$	16,781

(2) Drilling and rental operating income — drilling and rental revenues less direct drilling and rental operating expenses, including depreciation and amortization expense.

RESULTS OF OPERATIONS (continued)

U.S. Drilling Segment

     Revenues for the U.S drilling segment increased $21.4 million to $61.6 million for the quarter ended March 31, 2007 as compared to the quarter ended March 31, 2006. The increased revenues were primarily due to a $14.3 million increase for our barge drilling operations from significantly higher dayrates that more than offset fewer operating days, primarily related to the sale of workover Barge Rigs 9 and 26 (see Note 5) and the refurbishment of Barge Rig 8 during the first quarter of 2007. Barge Rig 12 was undergoing an upgrade from workover to deep drilling status until late May 2006 and newly constructed Barge Rig 77 also began operations in December 2006. During the last half of 2006 we also had two repositioned international land rigs operating in the U.S. market which contributed $7.1 million to the increase in U.S. drilling segment revenues.

     Average dayrates for the deep drilling barge rigs increased approximately $13,800 per day in 2007 as compared to 2006. As a result of approximately 52 percent higher dayrates on all barge rigs, the addition of two land rigs and effective operating cost controls, gross margins, excluding depreciation and amortization, increased $12.1 million to $34.9 million. This increase includes $1.8 million for the two land rigs referred to above.

International Drilling Segment

     International drilling revenues decreased $20.2 million to $59.7 million during the first quarter of 2007 as compared to the first quarter of 2006. Of this decrease, $14.3 million is related to international land drilling revenues and $5.9 million to revenues from offshore operations. The decline in land revenues relates primarily to completion of our contracts for rigs working in Mexico, the release of rigs previously working under our TCO contract in Kazakhstan and the completion of our contract wells in Turkmenistan. The decline of $5.9 million in offshore operations is due primarily to the sale of our barge rigs in Nigeria in August 2006.

     Overall, land revenues in the CIS decreased by $13.1 million due to the TCO contract completion in 2006 ($13.2 million), the release of our three rigs in Turkmenistan ($4.9 million) during the third quarter of 2006 and a reduction in revenues related to our Sakhalin Island operations ($2.1 million) primarily related to lower reimbursable revenues. In the Karachaganak area of Kazakhstan, revenues increased by $3.2 million as a result of higher dayrates and the addition of Rig 107 (which was released in late December 2005 from the TCO contract) which commenced operations at the end of March 2006 and the addition of Rigs 249 and 258 (from the TCO contract) which earned pre-mobilization standby dayrates of $2.1 million during the current quarter. In addition Rig 236, which began drilling in Kazakhstan in late 2006, contributed $3.9 million in revenues.

     In our Asia Pacific region, revenues and gross margin, excluding depreciation and amortization, remained relatively unchanged.

     Gross margin, excluding depreciation and amortization, for international land operations decreased by $5.8 million, due primarily to the completion of contract wells in Mexico and under our TCO contract, the release of rigs in Turkmenistan, and shifting of Rig 122 and 256 revenue to U.S. operations. In Colombia, gross margin, excluding depreciation and amortization, increased by $3.8 million as two rigs drilled the entire quarter in 2007, compared to no rigs operating in Colombia in the first quarter of 2006. In the Karachaganak area of Kazakhstan, gross margin, excluding depreciation and amortization, increased $2.8 million as two rigs operated all of the first quarter of 2007, compared to one rig in the first quarter of 2006 and also as a result of pre-mobilization standby revenues on another two rigs received in the first quarter of 2007.

     International offshore revenues declined $5.9 million to $7.8 million during the first quarter of 2007 compared to the first quarter of 2006. This decrease was due primarily to the sale of our Nigerian barge rigs in the third quarter of 2006. Revenues for the Rig 53 contract in Mexico increased $0.6 million due to higher dayrates. Gross margins, excluding depreciation and amortization, for international offshore operations increased $1.2 million as a result of the higher dayrates in Mexico combined with better cost control in the Caspian Sea, offset partially by the sale of the Nigerian barge rigs.

RESULTS OF OPERATIONS (continued)

Rental Tools Segment

     Rental tools revenues increased $2.7 million to $30.0 million during the first quarter of 2007 as compared to the first quarter of 2006. The increase was due primarily to an increase in rental revenues of $1.2 million from our Texas operations, $1.9 million from our Wyoming operations, partially offset by a decline of $0.4 million at our New Iberia, Louisiana location.

     Revenues increased primarily due to higher demand and higher rental tool sales. Rental tools gross margins increased $2.0 million to $18.8 million for the current quarter as compared to the first quarter of 2006. Gross margin percentage increased to 63 percent in the current quarter as compared to 62 percent in the comparable period in 2006.

Other Financial Data

     Gain on asset dispositions increased by $15.9 million, due to the gain on the sale of the two workover barge rigs in the first quarter of 2007. Interest expense declined $2.8 million in the first quarter of 2007 as compared to the first quarter of 2006 due to lower outstanding debt and capitalization of $1.5 million in interest on rig construction projects in 2007. There was no capitalized interest in the first quarter of 2006. Interest income increased $0.4 million due to higher investments in marketable securities in the first quarter of 2007 as compared to 2006. General and administration expense decreased $1.8 million due to a change in estimate related to our allocation of corporate costs to operations based on an estimate of actual time spent.

     In 2004, we entered into two variable-to-fixed interest rate swap agreements, which are still outstanding. The swap agreements do not qualify for hedge accounting and accordingly, we are reporting the mark-to-market change in the fair value of the interest rate derivatives currently in earnings. For the three months ended March 31, 2007, we recognized a $0.4 million decrease in the fair value of the derivative positions and for the three months ended March 31, 2006 we recognized a $0.8 million increase in the fair value of the derivative positions. For additional information see Note 8 in the notes to the unaudited consolidated condensed financial statements.

     Income tax expense was $24.1 million for the first quarter of 2007 as compared to $14.5 million for the first quarter of 2006. The $9.6 million increase in taxes during the first quarter of 2007 was due primarily to the impact of the recognized gain on the sale of the two U.S. workover barge rigs, the inclusion of FIN 48 interest described in Note 6 and the increase in operating income.

LIQUIDITY AND CAPITAL RESOURCES

Operating Cash Flows

     As of March 31, 2007, we had cash, cash equivalents and marketable securities of $157.6 million, an increase of $2.5 million from December 31, 2006. The primary sources of cash for the three-month period as reflected on the consolidated condensed statements of cash flows were $33.7 million provided by operating activities and $51.9 million used in investing activities. Major investing activities during the three-month period ended March 31, 2007 included proceeds of $20.5 million from the sale of two workover barge rigs, and $53.0 million for capital expenditures. Major capital expenditures for the period included $15.5 million on construction of new land rigs and $21.0 million for tubulars and other rental tools for the expansion of Quail Tools.

24

LIQUIDITY AND CAPITAL RESOURCES

Operating Cash Flows (continued)

     As of March 31, 2006, we had cash and cash equivalents of $186.6 million, an increase of $126.5 million from December 31, 2005. The primary sources of cash for the three-month period as reflected on the consolidated condensed statements of cash flows were $35.7 million provided by operating activities, $61.6 million from the sale of marketable securities and $107.8 million from financing activities, $99.9 million of which was net proceeds on our common stock issuance in January 2006 as detailed in a subsequent paragraph. The primary uses of cash for the three-month period ended March 31, 2006 were $35.9 million for capital expenditures and $43.6 million for purchases of marketable securities. Major capital expenditures for the period included $6.4 million on construction of four new 2,000 HP land rigs, $11.1 million for tubulars and other rental tools for Quail Tools, $3.0 million on the conversion of workover barge Rig 12 to a deep drilling barge and $2.6 million on construction of a new ultra-deep drilling barge.

Financing Activity

     On January 18, 2006 we issued 8,900,000 shares of our common stock pursuant to a Free Writing Prospectus dated January 17, 2006 and a Prospectus Supplement dated January 18, 2006. On January 23, 2006, we realized $11.23 per share or a total of $99.9 million of net proceeds before expenses, but after underwriter discount, from the offering. Proceeds from this offering are being used for capital expansions, including rig upgrades, new rig construction and expansion of our rental tools business.

     Our current $40.0 million credit facility is available for general corporate purposes and to fund reimbursement obligations under letters of credit the banks issue on our behalf pursuant to this facility. Availability under the revolving credit facility is subject to a borrowing base limitation based on 85 percent of eligible receivables plus a value for eligible rental tools equipment. The credit facility calls for a borrowing base calculation only when the credit facility has outstanding loans, including letters of credit, totaling at least $25.0 million. As of March 31, 2007, there were $21.1 million in letters of credit outstanding and no loans. On March 1, 2006, an amendment was signed to eliminate the $25.0 million sub-limit for letters of credit and to give us the ability to call outstanding Senior Notes and Senior Floating Rate Notes without limitation concerning commitments, including letters of credit, under the credit facility.

     We had total long-term debt of $329.2 million as of March 31, 2007. The long-term debt included:

• $100.0 million aggregate principal amount of Senior Floating Rate Notes bearing interest at a rate of LIBOR plus 4.75%, which are due September 1, 2010; and

• $225.0 million aggregate principal amount of 9.625% Senior Notes, which are due October 1, 2013 plus an associated $4.2 million in unamortized debt premium.

     As of March 31, 2007, we had approximately $176.5 million of liquidity. This liquidity was comprised of $157.6 million of cash, cash equivalents and marketable securities on hand and $18.9 million of availability under the revolving credit facility. We do not have any unconsolidated special-purpose entities, off-balance-sheet financing arrangements or guarantees of third-party financial obligations. We have no energy or commodity contracts.

(1)	Long-term debt includes the principal and interest cash obligations of the 9.625% Senior Notes. The remaining unamortized premium of $4.2 million is not included in the contractual cash obligations schedule. A portion of the interest on the Senior Floating Rate Notes has been fixed through variable-to-fixed interest rate swap agreements. The issuer (Bank of America, N.A.) of each swap has the option to extend each swap for an additional two years at the termination of the initial swap period. For the purpose of this table, the highest interest rate currently hedged is used in calculating the interest on future floating rate periods.
(2)	Operating leases consist of lease agreements in excess of one year for office space, equipment, vehicles and personal property.
(3)	We have purchase commitments outstanding as of March 31, 2007, related to rig upgrade projects and new rig construction.
(4)	We have a $40.0 million revolving credit facility. As of March 31, 2007, no amounts have been drawn down, but $21.1 million of availability has been used to support letters of credit that have been issued, resulting in an estimated $18.9 million of availability. The revolving credit facility expires in December 2007.

OTHER MATTERS

Critical Accounting Policies

Accounting for Uncertainty in Income Taxes – Our accounting policy for income taxes was recently modified due to the adoption of FIN 48 on January 1, 2007. In June 2006, the Financial Accounting Standards Board (FASB) issued Interpretation No. 48, “Accounting for Uncertainty in Income Taxes” (“FIN 48”). The preparation of financial statements in accordance with FIN 48 requires management to make estimates and assumptions that affect amounts of liabilities reported and related disclosures due to the uncertainty as to the final resolution of certain tax matters. We have discussed those estimates that we believe are critical and require the use of complex judgment in their application in Note 6 of our first quarter 2007 Form 10-Q. The application of the prescribed factors in evaluating and estimating our tax positions and tax benefits may result in recognition of liabilities due to uncertainties of certain tax positions. Because the recognition of liabilities may require periodic adjustments and may not necessarily imply any change in management’s assessment of the ultimate outcome of such tax matters, the amount recorded as a liability for unrecognized tax benefits may not accurately anticipate actual outcomes. Other than the adoption of FIN 48, our critical accounting policies and the methodologies and assumptions we apply under them have not materially changed since the date of our 2006 Form 10-K.

26

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     We use derivative instruments to manage risks associated with interest rate fluctuations in connection with our $100.0 million Senior Floating Rate Notes. These derivative instruments, which consist of two variable-to-fixed interest rate swaps, do not meet the hedge criteria in SFAS No. 133 and are therefore not designated as hedges. Accordingly, the change in the fair value of the interest rate swaps is recognized currently in earnings.

     As of March 31, 2007, we had the following derivative instruments outstanding related to our interest rate swaps, which are included in “Other noncurrent assets” and “Other current assets:”

Effective	Termination	Notional		Floating	Fixed			Fair
Date	Date	Amount		Rate	Rate			Value
(Dollars in Thousands)
September 1, 2005	September 2, 2008	$	50,000	Three-month LIBOR plus 475 basis points		8.83	%	$	543
September 1, 2005	September 4, 2007	$	50,000	Three-month LIBOR plus 475 basis points		8.48	%		398
								$	941

ITEM 4. CONTROLS AND PROCEDURES

     Evaluation of Disclosure Controls and Procedures – We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our Securities Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our chief executive officer and chief financial officer, as appropriate, to allow timely decisions regarding required disclosure based on the definition of “disclosure controls and procedures” in Rule 13a-15(e). In designing and evaluating the disclosure controls and procedures, management recognized that disclosure controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible disclosure controls and procedures. We performed evaluations under the supervision and with the participation of our management, including our chief executive officer and our chief financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of March 31, 2007. Based on the foregoing, our chief executive officer and chief financial officer concluded that our disclosure controls and procedures were effective at the reasonable assurance level at March 31, 2007.

     Changes in Internal Control Over Financial Reporting – There have been no changes in our internal control over financial reporting during the quarter ended March 31, 2007 covered by this report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
