NOTES TO THE UNAUDITED CONSOLIDATED INTERIM FINANCIAL STATEMENTS

1. BASIS OF PRESENTATION

The accompanying unaudited consolidated financial statements include the accounts of Core Laboratories N.V. and its subsidiaries for which we have a controlling voting interest and/or a controlling financial interest. These financial statements have been prepared in accordance with United States ("U.S.") generally accepted accounting principles ("GAAP") for interim financial information using the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, these financial statements do not include all of the information and footnote disclosures required by U.S. GAAP and should be read in conjunction with the financial statements and the summary of significant accounting policies and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2010.

Core Laboratories N.V. uses the equity method of accounting for investments in which it has less than a majority interest and over which it does not exercise control. Non-controlling interest has been recorded to reflect outside ownership attributable to consolidated subsidiaries that are less than 100% owned. In the opinion of management, all adjustments considered necessary for the periods presented have been included in these financial statements. Furthermore, the operating results presented for the three months ended March 31, 2011 may not necessarily be indicative of the results that may be expected for the year ended December 31, 2011.

Core Laboratories N.V.'s balance sheet information for the year ended December 31, 2010 was derived from the 2010 audited consolidated financial statements but does not include all disclosures in accordance with U.S. GAAP.

At our annual meeting on June 10, 2010, the shareholders approved an amendment to increase the authorized shares of our common stock from 100 million to 200 million and to increase the authorized shares of our preference stock from 3 million to 6 million. In addition, shareholders approved the two-for-one stock split authorized by the Supervisory Board and thereby reduced the par value of each share from EUR 0.04 to EUR 0.02. As a result of the stock split, shareholders of record on June 30, 2010 received an additional share of common stock for each common share held. The additional shares were distributed on July 8, 2010. All references in the consolidated financial statements and the accompanying notes to common shares, share prices, per share amounts and stock plans have been restated retroactively for the stock split.

Certain reclassifications were made to prior period amounts in order to conform to the current period presentation. These reclassifications had no impact on the reported net income for the three month period ended March 31, 2011.

References to "Core Lab", "we", "our" and similar phrases are used throughout this Quarterly Report on Form 10-Q and relate collectively to Core Laboratories N.V. and its consolidated subsidiaries.

2. INVENTORIES

Inventories consist of the following (in thousands):

	March 31,		December 31,
	2011		2010
	(Unaudited)
Finished goods	$	28,839	$	24,476
Parts and materials		7,268		6,727
Work in progress		2,386		2,776
Total inventories, net	$	38,493	$	33,979

We include freight costs incurred for shipping inventory to customers in the Cost of Sales line of the Consolidated Statements of Operations.

3. GOODWILL AND INTANGIBLES

We account for intangible assets with indefinite lives, including goodwill, in accordance with the applicable accounting guidance, which requires us to evaluate these assets for impairment annually, or more frequently if an indication of impairment has occurred. Based upon our most recent evaluation, we determined that goodwill is not impaired. We amortize intangible assets with a defined term on a straight-line basis over their respective useful lives.

Return to Index

In 2010, we acquired fracture diagnostics assets for $9.0 million in cash. The acquisition was recorded in the Production Enhancement business segment and resulted in an increase of $5.6 million in goodwill and an increase of $3.2 million in intangible assets. The intangible assets will be amortized over a period of 36 to 60 months.

4. DEBT AND CAPITAL LEASE OBLIGATIONS

Debt is summarized in the following table (in thousands):

	March 31,			December 31,
	2011			2010
	(Unaudited)
Senior exchangeable notes	$	109,839		$	156,407
Discount on senior exchangeable notes		(4,523	)		(8,864	)
Net senior exchangeable notes	$	105,316		$	147,543

In 2006, Core Laboratories LP, a wholly owned subsidiary of Core Laboratories N.V., issued $300 million aggregate principal amount of Senior Exchangeable Notes (the "Notes") which are fully and unconditionally guaranteed by Core Laboratories N.V. and mature on October 31, 2011. The Notes bear interest at a rate of 0.25% per year paid on a semi-annual basis.

With the additional amortization of the discount on the Notes, the effective interest rate is 7.48% for the three-month period ended March 31, 2011, which resulted in additional non-cash interest expense of $2.2 million and $3.8 million for the three months ended March 31, 2011 and 2010, respectively. Each Note carries a $1,000 principal amount and is exchangeable into shares of Core Laboratories N.V. common stock under certain circumstances at an exchange price of $45.62 per share, or 21.9190 shares per Note. Upon exchange, holders will receive cash for the principal amount plus any amount related to fractional shares, and any excess exchange value will be delivered in whole shares of Core Laboratories N.V. common stock at the completion of the valuation period as defined under our Notes agreement. At March 31, 2011, the Notes were trading at 223.0% of their face value which is equivalent to $135.1 million of value in excess of the aggregate principal amount. At December 31, 2010, the Notes were trading at 197% of their face value which is equivalent to $151.7 million of value in excess of the aggregate principal amount. There were 109,839 and 156,407 Notes outstanding at March 31, 2011 and December 31, 2010, respectively.

Under the terms of the Notes, defined criteria was met which allowed the Notes to be early exchanged during the first quarter of 2011, and as a result the equity component of the Notes at March 31, 2011 was classified as temporary equity. This balance combined with the debt amount reflects the amount that could result in cash settlement upon exchange. We received ten requests to exchange 46,568 Notes during the first quarter of 2011 which were settled for $46.6 million in cash and 556,455 shares of our common stock, all of which were treasury shares, resulting in a loss of $0.6 million. We also received five requests during the first quarter to exchange 808 Notes which we will settle during the second quarter upon completion of the requisite holding period per the Note Indenture agreement.

The same criteria was also met allowing the Notes to be early exchanged during the second quarter of 2011. Subsequent to March 31, 2011, we have received an additional request to exchange five Notes which we will settle during the second quarter.

We maintain a revolving credit facility (the "Credit Facility") that allowed for an aggregate borrowing capacity of $125.0 million at March 31, 2011. The Credit Facility also provided an option to increase the commitment under the Credit Facility to $200.0 million, if certain conditions are met. Subsequently, on April 19, 2011, the Credit Facility was amended increasing the aggregate borrowing capacity to $300 million with an option to increase the commitment to $350 million if certain conditions are met. The Credit Facility bears interest at variable rates from LIBOR plus 1.75% to a maximum of LIBOR plus 2.50%. Any outstanding balance under the Credit Facility is due in December 2015 when the Credit Facility matures. Interest payment terms are variable depending upon the specific type of borrowing under this facility. Our available capacity is reduced by outstanding letters of credit and performance guarantees and bonds totaling $14.1 million at March 31, 2011 relating to certain projects in progress. Our available borrowing capacity under the Credit Facility at March 31, 2011 was $110.9 million. As of March 31, 2011, we had $17.8 million of outstanding letters of credit and performance guarantees and bonds in addition to those under the Credit Facility.

The terms of the Credit Facility require us to meet certain financial and operational covenants. We believe that we were in compliance with all such covenants at March 31, 2011. All of our material, wholly owned subsidiaries are guarantors or co-borrowers under the Credit Facility.

5. PENSIONS AND OTHER POSTRETIREMENT BENEFITS

We provide a noncontributory defined benefit pension plan covering substantially all of our Dutch employees (the "Dutch Plan") who were hired prior to 2007 based on years of service and final pay or career average pay, depending on when the employee began participating. Employees are immediately vested in the benefits earned. We fund the future obligations of the Dutch Plan by purchasing investment contracts from a large multi-national insurance company. The investment contracts are purchased annually and expire after five years at which time they are replaced with new contracts that are adjusted to include changes in the benefit obligation for the current year and redemption of the expired contracts. We determine the fair value of

these plan assets with the assistance of an actuary using observable inputs (Level 2). We make annual premium payments to the insurance company, based on each employee's age and current salary.

The following table summarizes the components of net periodic pension cost under this plan for the three months ended March 31, 2011 and 2010 (in thousands):

	Three Months Ended March 31,
	2011			2010
	(Unaudited)
Service cost	$	335		$	323
Interest cost		432			376
Expected return on plan assets		(201	)		(119	)
Amortization of transition asset		(22	)		(22	)
Amortization of prior service cost		40			40
Amortization of net loss		84			94
Net periodic pension cost	$	668		$	692

During the three months ended March 31, 2011, we contributed approximately $1.9 million, as determined by the insurance company, to fund the estimated 2011 premiums on investment contracts held by the Dutch Plan.

We have adopted a non-qualified deferred compensation plan that allows certain highly compensated employees to defer a portion of their salary, commission and bonus, as well as the amount of any reductions in their deferrals under the deferred compensation plan for employees in the United States (the "Deferred Compensation Plan"), due to certain limitations imposed by the U.S. Internal Revenue Code of 1986, as amended (the "Internal Revenue Code"). The Deferred Compensation Plan also provides for employer contributions to be made on behalf of participants equal in amount to certain forfeitures of, and/or reductions in, employer contributions that participants could have received under the 401(k) Plan in the absence of certain limitations imposed by the Internal Revenue Code. Employer contributions to the Deferred Compensation Plan vest ratably over a period of five years. Contributions to the plan are invested in equity and other investment fund assets, and carried on the balance sheet at fair value. The benefits under these contracts are fully vested and payment of benefits generally commences as of the last day of the month following the termination of services except that the payment of benefits for select executives generally commences on the first working day following a six month waiting period following the date of termination.

On a recurring basis, we use the market approach to value certain assets and liabilities at fair value at quoted prices in an active market (Level 1) and certain assets and liabilities using significant other observable inputs (Level 2). We do not have any assets or liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3). Gains and losses related to the fair value changes in the deferred compensation assets and liabilities are recorded in General and Administrative Expenses in the Consolidated Statements of Operations. The following table summarizes the fair value balances (in thousands):

(Unaudited)			Fair Value Measurement at March 31, 2011
	Total		Level 1		Level 2		Level 3
Assets:
Deferred compensation plan trust assets	$	9,806	$	-	$	9,806	$	-

6. COMMITMENTS AND CONTINGENCIES

We have been and may from time to time be named as a defendant in legal actions that arise in the ordinary course of business. These include, but are not limited to, employment-related claims and contractual disputes or claims for personal injury or property damage which occur in connection with the provision of our products and services. Management does not currently believe that any of our pending contractual, employment-related, personal injury or property damage claims and disputes will have a material effect on our future results of operations, financial position or cash flow.

7. EQUITY

During the three months ended March 31, 2011, we repurchased 550,765 of our common shares for $49.8 million. Included in this total were rights to 6,271 shares valued at $0.6 million that were surrendered to us pursuant to the terms of a stock-based compensation plan in consideration of the participants' tax burdens that may result from the issuance of common shares under that plan. Such common shares, unless cancelled, may be reissued for a variety of purposes such as future acquisitions, employee stock awards, exchange of the Notes, or settlement of warrants.

In February 2011, we paid a quarterly dividend of $0.25 per share of common stock. In addition, on April 18, 2011, we declared a quarterly dividend of $0.25 per share of common stock for shareholders of record on April 28, 2011 and payable on May 27, 2011.

We compute basic earnings per common share by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted earnings per common and potential common shares include additional shares in the weighted average share calculations associated with the incremental effect of dilutive employee stock options, restricted stock awards and contingently issuable shares, as determined using the treasury stock method. The

following table summarizes the calculation of weighted average common shares outstanding used in the computation of diluted earnings per share (in thousands):

	Three Months Ended March 31,
	2011		2010
	(Unaudited)
Weighted average basic common shares outstanding		45,225		44,836
Effect of dilutive securities:
Stock options		27		58
Contingent shares		57		29
Restricted stock and other		318		524
Senior exchangeable notes		1,257		1,345
Warrants		2,257		28
Weighted average diluted common and potential common shares outstanding		49,141		46,820

In 2006, we sold warrants on our common shares, which have an exercise price of $61.42 per share, and will settle in January 2012. The warrant agreement calls for the net value of these warrants to be settled with Core Laboratories N.V. common shares. Included in the table above are 2,257,000 and 28,000 shares which were added to the share count for the three months ended March 31, 2011 and 2010, respectively, because the average share price exceeded the strike price of the warrants. These shares were included in calculating the impact to our dilutive earnings per share for the three months ended March 31, 2011 and 2010.

10. INCOME TAX EXPENSE

The effective tax rates for the three months ended March 31, 2011 and 2010 were 14.0% and 31.8%, respectively. Included in income tax expense is the reversal in the quarter ended March 31, 2011 of $10.4 million in tax liabilities provided over the period 2007-2010 as a result of recently concluded audits of prior year returns. The liability reversal reflects the impact of positions sustained in certain audits.

11. SEGMENT REPORTING

We operate our business in three reportable segments: (1) Reservoir Description, (2) Production Enhancement and (3) Reservoir Management. These business segments provide different services and utilize different technologies.

*	Reservoir Description: Encompasses the characterization of petroleum reservoir rock, fluid and gas samples. We provide analytical and field services to characterize properties of crude oil and petroleum products to the oil and gas industry.

Outlook

We continue our efforts to expand our market presence by opening or expanding facilities in strategic areas and realizing synergies within our business lines. We believe our market presence provides us a unique opportunity to service clients who have global operations in addition to the national oil companies.

We have established internal earnings targets that are based on market conditions existing at the time our targets were established. Based on recent activity levels, we believe that the current level of activities, workflows, and operating margins both outside North America and within North America will grow moderately during 2011.

Operating Results for the Three Months Ended March 31, 2011 Compared to the Three Months Ended March 31, 2010 (unaudited)

Service Revenue

Service revenue increased to $153.1 million for the first quarter of 2011, up 7% when compared to $143.4 million for the first quarter of 2010. The increase in service revenue was due, in part, to the increased demand for reservoir rock studies, reservoir fluids phase-behavior studies, and for crude oil testing, inspection, distillation, assay, fractionation and characterization projects worldwide. Our large scale core analyses and reservoir fluid projects combined with our fluid and derived products inspection, calibration and assay work continue to provide meaningful revenue streams in the Middle East, Asia-Pacific and the southern-Atlantic margins off the coasts of West Africa and Brazil. Activity in North American shale plays, especially the liquid-rich plays, has also led to growth in reservoir characterization projects.

Product Sales Revenue

Revenue associated with product sales increased to $53.6 million for the first quarter of 2011, up 19 % from $44 .9 million for the first quarter of 2010. The increase in revenue was driven by the acceptance of and demand for our specialized completion products introduced over the last three years which has led to increased market share in North American natural gas and oil shale reservoirs and has increased market penetration in the Middle East, West Africa, and Asia-Pacific perforating markets. These specialized optimizing technologies are focused on high-end well completion and stimulation programs mainly in the Haynesville, Marcellus, Montney and Eagle Ford shale plays and in multi-stage completions in the Bakken, Niobrara and Eagle Ford oil-shale plays. We are also providing high margin completion and recompletion technologies and services to be used in reworking major, giant, and super-giant fields in southern Iraq.

Cost of Services

Cost of services expressed as a percentage of service revenue was 66% for the quarter ended March 31, 2011, unchanged from the same period in 2010.

Return to Index

Cost of Product Sales

Cost of sales expressed as a percentage of product sales revenue was 67% for the quarter ended March 31, 2011, unchanged from the same period in 2010.

General and Administrative Expenses

General and administrative expenses totaled $9.5 million for the first quarter of 2011, up from the $6.4 million incurred in the first quarter of 2010, but up only slightly from $9.0 million in the previous quarter. The increase in general and administrative expenses was due to compensation related expenses.

Depreciation and Amortization Expense

Depreciation and amortization expense was $5.8 million for the first quarter of 2011, unchanged from the first quarter of 2010.

Other (Income), Net

Other (income) expense, net consisted of the following for the quarter ended March 31, 2011 and 2010 (in thousands):

Interest Expense

Interest expense for the three months ended March 31, 2011 and 2010 was $2.4 million and $4.1 million, respectively, which included $2.2 million and $3.8 million, respectively, of non-cash interest expense due to the amortization of the discount on the Notes. As 128,819 of our $1,000 principal amount Notes were exchanged between March 31, 2010 and March 31, 2011, the associated discount was moved to equity resulting in a lower amount of amortization to interest expense.

Segment Analysis

Our operations are managed primarily in three complementary segments - Reservoir Description, Production Enhancement and Reservoir Management. The following tables summarize our results by operating segment for the three months ended March 31, 2011 and 2010 (in thousands):

	Three Months Ended March 31,					% Change

Consolidated	$	56,499	$	51,413			10	%

(1) "Corporate and Other" represents those items that are not directly related to a particular segment
"NM" means not meaningful

Reservoir Description

Revenue from the Reservoir Description segment increased 3%, or $3.5 million, to $107.6 million in the first quarter of 2011, compared to $104.1 million in the first quarter of 2010. Although certain North African and Middle Eastern countries have been affected by political instability, this segment’s operations continued to benefit from large-scale core analyses and reservoir fluids characterization studies from Asia-Pacific areas, offshore West Africa and the Middle East, including Iraq, Kuwait, and the United Arab Emirates. This segment continued to realize increased demand for reservoir fluids phase-behavior studies, and for crude oil testing, inspection, distillation, assay, fractionation and characterization projects worldwide.

Operating income in the first quarter of 2011 increased by 5%, or $1.3 million, to $26.4 million compared to $25.1 million for the first quarter of 2010. Operating margin for the quarter ended March 31, 2011 was 25%, compared to 24% for the same period in 2010. This segment continues to focus on emphasizing higher value, and thus higher margin services on internationally-based development and production-related crude oil projects in addition to de-emphasizing the more cyclical exploration-related projects.

Return to Index

Production Enhancement

Revenue from the Production Enhancement segment increased by 19%, or $13.3 million, to $82.1 million in the first quarter of 2011 compared to $68.8 million in the first quarter of 2010. The revenue increase was due to the increased market share of our perforating charges and gun systems particularly in markets relating to horizontal well developments of gas-shale and oil-shale reservoirs, as well as the second phase of a multi-phase field-flood monitoring project in offshore West Africa.

Operating income in the first quarter of 2011 increased by 11%, or $2.4 million, to $23.3 million from $20.9 million for the first quarter of 2010. Operating margins decreased to 28% in the first quarter of 2011 compared to 30% for the same period in 2010. The increase in operating income was primarily driven by our continued market penetration of higher-revenue services including our proprietary and patented diagnostic technologies, such as SpectraChem ® Plus+, SpectraScan ® , ZeroWash ® , and our HERO™ line of perforating charges and gun systems and our new Horizontal Time-Delayed Ballistics Actuated Sequential Transfer (HTD Blast™) perforating system which is used for the perforation of extended-reach horizontal completions. This segment also began providing completion and recompletion technologies and services to be used in the reworking of major, giant, and super-giant fields in southern Iraq.

Reservoir Management

Revenue from the Reservoir Management segment increased by 10% in the first quarter of 2011 compared to the first quarter of 2010. The increase in revenue was due to ongoing interest in several of our existing multi-client reservoir studies including studies in the Montney Shale in northeastern British Columbia and northern Alberta, and the Eagle Ford Shale in south Texas, along with the continued participation in our North American Gas Shale Study and the increased participation in our Worldwide Oil and Natural Gas Shale Reservoir Study, which now contains shale cores from countries spanning the globe. Increased revenue was also provided by our proprietary studies which parallel our joint-industry projects, including studies of offshore Ivory Coast, Ghana and Nigeria, a gas-shale reconnaissance project in Indonesia and detailed proprietary reservoir studies for several companies active in the Wolfberry play in West Texas.

Operating income in the first quarter of 2011 increased 19% to $6.7 million from $5.6 million for the first quarter of 2010. The increase in operating income was primarily related to growth in our consortium projects and the delivery of completed consortium projects.

Liquidity and Capital Resources

General

We have historically financed our activities through cash on hand, cash flows from operations, bank credit facilities, or the issuance of debt and equity financing.

We utilize the non-GAAP financial measure of free cash flow to evaluate our cash flows and results of operations. Free cash flow is defined as net cash provided by operating activities (which is the most directly comparable GAAP measure) less capital expenditures. Management believes that free cash flow provides useful information to investors regarding the cash that was available in the period that was in excess of our needs to fund our capital expenditures and operating activities. Free cash flow is not a measure of operating performance under GAAP, and should not be considered in isolation nor construed as an alternative to operating profit, net income (loss) or cash flows from operating, investing or financing activities, each as determined in accordance with GAAP. Free cash flow does not represent residual cash available for distribution because we may have other non-discretionary expenditures that are not deducted from the measure. Moreover, since free cash flow is not a measure determined in accordance with GAAP and thus is susceptible to varying interpretations and calculations, free cash flow as presented, may not be comparable to similarly titled measures presented by other companies. The following table reconciles this non-GAAP financial measure to the most directly comparable measure calculated and presented in accordance with GAAP for the three months ended March 31, 2011 and 2010 (in thousands):

	Three Months Ended March 31,				% Change
	2011		2010			2011/2010
Free cash flow calculation:	(Unaudited)
Net cash provided by operating activities	$	58,022	$	62,366		(7	%)
Less: capital expenditures		4,379		6,155		(29	%)
Free cash flow	$	53,643	$	56,211		(5	%)

Return to Index

The decrease in free cash flow in 2011 compared to 2010 was primarily attributable to a build-up of inventories as a result of higher demand in 2011 partially offset by an increase in net income and a decrease in capital expenditures.

Cash Flows

The following table summarizes cash flows for the three months ended March 31, 2011 and 2010 (in thousands):

	Three Months Ended March 31,						% Change
	2011			2010				2011/2010
Cash provided by/(used in):	(Unaudited)
Operating activities	$	58,022		$	62,366			(7	%)
Investing activities		(4,624	)		(15,614	)		(70	%)
Financing activities		(107,267	)		(89,029	)		20	%
Net change in cash and cash equivalents	$	(53,869	)	$	(42,277	)		27	%

The decrease in cash flows provided by operating activities was primarily attributable to a build-up of inventories as a result of higher demand in 2011.

Cash flows used in investing activities were higher during the first quarter of 2010 due to an acquisition for $9.0 million.

The increase in cash flows used in financing activities primarily relates to the early exchange of the Notes. We received 10 requests during the first quarter of 2011 to exchange 46,568 of our $1,000 face value Notes which were settled during the first quarter of 2011 for $46.6 million in cash and 556,455 shares of our common stock, all of which were treasury shares. In the first quarter of 2011, our Board of Directors announced an increase of our quarterly dividend resulting in an increase of $8.6 million in dividends paid during the first quarter of 2011 over the same period of 2010. This was partially offset by a decrease in the number of shares repurchased under our common share repurchase program. In the first three months of 2011, we repurchased 550,765 shares for an aggregate price of $49.8 million compared to 703,902 shares for an aggregate price of $86.5 million during the same period in 2010.

Credit Facilities and Available Future Liquidity

In 2006, Core Laboratories LP, a wholly owned subsidiary of Core Laboratories N.V., issued $300 million aggregate principal amount of Senior Exchangeable Notes which are fully and unconditionally guaranteed by Core Laboratories N.V. and mature on October 31, 2011.

Under the terms of the Notes, defined criteria was met which allowed the Notes to be early exchanged during the first quarter of 2011, and as a result the equity component of the Notes at March 31, 2011 was classified as temporary equity. This balance combined with the debt amount reflects the amount that could result in cash settlement upon exchange. We received 10 requests to exchange 46,568 Notes during the first quarter of 2011 which were settled for $46.6 million in cash and 556,455 shares of our common stock, all of which were treasury shares, resulting in a loss of $0.6 million. We also received five requests during the first quarter to exchange 808 Notes which we will settle during the second quarter upon completion of the requisite holding period per the Note Indenture agreement.

Return to Index

Our ability to maintain and grow our operating income and cash flow depends, to a large extent, on continued investing activities. We are a Netherlands holding company and substantially all of our operations are conducted through subsidiaries. Consequently, our cash flow depends upon the ability of our subsidiaries to pay cash dividends or otherwise distribute or advance funds to us. We believe our future cash flows from operations, supplemented by our borrowing capacity and issuances of additional equity, should be sufficient to fund our debt requirements, capital expenditures, working capital, dividend payments and future acquisitions.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

There have been no material changes in market risk from the information provided in Item 7A. "Quantitative and Qualitative Disclosures About Market Risk" in our Annual Report on Form 10-K for the fiscal year ended December 31, 2010.

Item 4. Controls and Procedures

A complete discussion of our controls and procedures is included in our Annual Report on Form 10-K for the year ended December 31, 2010.

Disclosure Controls and Procedures

Our management, under the supervision of and with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures, as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), as of the end of the period covered by this report. Our disclosure controls and procedures are designed to provide reasonable assurance that the information required to be disclosed by us in our reports filed or submitted under the Exchange Act is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure and is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC. Based on such evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were effective as of March 31, 2011 at the reasonable assurance level.

Our management does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent all errors and all fraud. Further, the design of disclosure controls and internal control over financial reporting must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within a company have been detected.

Changes in Internal Control Over Financial Reporting

There have been no changes in our system of internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act, during our fiscal quarter ended March 31, 2011, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

IV.

Vesting

4.1 Vesting/Lapse of Forfeiture Restrictions

(a) As soon as administratively practicable after the last day of the Performance Period, the Committee shall determine the EBIT, Ending Shareholders’ Equity and Return on Equity for the Performance Period. The Committee’s determinations pursuant to the preceding sentence shall be certified by the Committee in writing and delivered to the Secretary of the Company. For purposes of the preceding sentence, approved minutes of the Committee meeting in which the certification is made shall be treated as a written certification. At the time of such certification and based on the Return on Equity for the Performance Period, the Restricted Performance Shares shall Vest in accordance with the following schedule (rounded to the nearest whole share):

Return on Equity for the Performance Period	Percentage of Restricted Performance Shares Vesting
At or above the Full Vesting ROE Percentage	100%
Above the Threshold Vesting ROE Percentage but less than the Full Vesting ROE Percentage	Interpolated percentage between 20% and 100%
At the Threshold Vesting ROE Percentage	20%
Below the Threshold Vesting ROE Percentage	0%

The interpolated percentage referred to in the schedule above shall be determined by increasing the 20% Vesting percentage for a Return on Equity equal to the Threshold Vesting ROE Percentage by the Incremental Percentage for each one-tenth of one percent (0.1%) by which the Return on Equity exceeds the Threshold Vesting ROE Percentage. To illustrate, if, for the Performance Period, the Full Vesting ROE Percentage is 18.0%, the Threshold Vesting ROE Percentage is 12.0%, and the Return on Equity is 15.6%, then the Incremental Percentage is 1⅓% (80% divided by (10 multiplied by (18.0% minus 12.0%))). Since the Return on Equity exceeds the Threshold Vesting ROE Percentage in this example by 3.6% (or 36 one-tenth of one percent increments), the Vesting percentage shall be 68% (20% plus (1⅓% multiplied by 36)).

(b) Notwithstanding any provision of Section 4.1(a) to the contrary and except as provided in Section 4.2 and Section 4.3, no Restricted Performance Shares shall Vest if Participant’s Service is terminated prior to the last day of the Performance Period for reasons other than Succession Termination, death or disability.

4.2 Acceleration of Vesting

. In the event of a Change in Control prior to the last day of a Performance Period and while Participant is in the Service of the Company or a Subsidiary, all of the Restricted Performance Shares with respect to such Performance Period shall Vest as of the effective date of such Change in Control.

4.3 Effect of Termination of Service on Vesting .

(a) Upon termination of Participant’s Service for any reason other than Succession Termination, death or disability, the Restricted Performance Shares shall be immediately forfeited to the extent not then Vested.

(b) Upon termination of Participant’s Service by reason of Succession Termination, death or disability, the Restricted Performance Shares shall not be immediately forfeited, but rather may become Vested as provided in Section 4.1 based on the Return on Equity for the Performance Period.

Delivery of Restricted Performance Shares

5.1 Delivery of Restricted Performance Shares

The prohibitions of Section 3.1 shall not apply to the transfer of Restricted Share awards pursuant to a plan of reorganization of the Company, but the stock, securities or other property received in exchange therefor shall also become subject to the Forfeiture Restrictions and provisions governing the lapsing of such Forfeiture Restrictions applicable to the original Restricted Performance Shares for all purposes of this Agreement.

Prior to the time the Restricted Performance Shares are issued and delivered, Participant will not have the right to vote any Restricted Performance Shares, to receive or retain any dividends or distributions paid or distributed on issued and outstanding shares of Common Shares or to exercise any other rights, powers and privileges of a shareholder with respect to any Restricted Performance Shares. In accordance with the provisions of Article V, the Company shall deliver to Participant stock certificates, or an equivalent evidence of share ownership , issued in Participant’s name for the number of Restricted Performance Shares that have become Vested.

6.3 Corporate Acts . The existence of the Restricted Performance Share awards shall not affect in any way the right or power of the Supervisory Board or the shareholders of the Company to make or authorize any adjustment, recapitalization, reorganization or other change in the Company’s capital structure or its business, any merger or consolidation of the Company, any issue of debt or equity securities, the dissolution or liquidation of the Company or any sale, lease, exchange or other disposition of all or any part of its assets or business or any other corporate act or proceeding; provided, however, that in the event of a stock split, stock dividend paid in shares, or similar reorganization affecting all or substantially all of the Company’s shares, the Restricted Shares shall similarly and automatically be split or reorganized without further action or decision by the Company or the Committee. The prohibitions of Section 3.1 shall not apply to the transfer of Restricted Share awards pursuant to a plan of reorganization of the Company, but the stock, securities or other property received in exchange therefor shall also become subject to the Forfeiture Restrictions and provisions governing the lapsing of such Forfeiture Restrictions applicable to the original Restricted Performance Shares for all purposes of this Agreement.

VII.

Miscellaneous

7.1 Service Relationship . For purposes of this Agreement, any question as to whether and when there has been a termination of Participant’s Service, and the cause of such termination, shall be determined by the Committee, and its determination will be final. Without limiting the scope of the preceding sentence, it is expressly provided that Participant shall be considered to have terminated Service at the time of the termination of the “Subsidiary” status under the Plan of the entity or other organization that employs Participant.

7.2 Notices . For purposes of this Agreement, notices and all other communications provided for herein will be in writing and will be deemed to have been duly given when personally delivered or (i) if Participant is outside of the United States at the time of transmission of such notice, when sent by courier, facsimile, or electronic mail, and (ii) if Participant is within the United States at the time of transmission of such notice, when mailed by United States registered or certified mail, return receipt requested, postage prepaid, addressed to the Company at its principal executive office and to Participant at the last address filed with the Company or to such other address as either party may furnish to the other in writing in accordance herewith, except that notices of changes of address will be effective only upon receipt.

7.3 Restrictions on Transfer of Shares . No Restricted Performance Shares may be sold, exchanged, transferred (including, without limitation, any transfer to a nominee or agent of Participant), assigned, pledged, hypothecated, or otherwise disposed of, including by operation of law, in any manner that violates the Forfeiture Restrictions and any other provisions of this Agreement, and, until the date on which such Forfeiture Restrictions lapse, any such attempted disposition shall be void. The Company shall not be required (i) to transfer on its books any shares that will have been transferred in violation of this Agreement or (ii) to treat as owner of such shares, to accord the right to vote as such owner, or to pay dividends to any transferee to whom such shares will have been so transferred.

7.4 Withholding of Tax . To the extent that the receipt of Restricted Performance Shares or the lapse of any Forfeiture Restriction results in compensation income to Participant for federal or state income tax purposes, Participant shall deliver to the Company at the time of such event such amount of money or Common Shares as the Company may require to meet all obligations under applicable tax laws or regulations, and, if Participant fails to do so, the Company is authorized to withhold or cause to be withheld from any cash or Common Shares remuneration then or thereafter payable to Participant for any tax attributable to the Participant required to be withheld by reason of such resulting compensation income.

7.5 No Employment Rights Conferred . No provision of this Agreement shall confer any right upon Participant to continued employment with the Company or any Subsidiary, if applicable.

7.6 Limitation of Rights . No provision of this Agreement shall be construed to give Participant or any other person any interest in any fund or in any specified asset or assets of the Company or a Subsidiary.

7.7 Binding Effect . This Agreement shall be binding upon and inure to the benefit of any successors to the Company and all persons lawfully claiming under Participant.

7.8 Governing Law . This Agreement shall be governed by, and construed in accordance with, the laws of the state of Texas.
