Profit Sharing and Retirement Plan: We have audited the accompanying statements of net assets available for benefits of Core Laboratories, Inc. Profit Sharing and Retirement Plan (the "Plan") as of December 31, 1996 and 1995, and the related statement of changes in net assets available for benefits for the year ended December 31, 1996. These financial statements and the schedules referred to below are the responsibility of the Plan administrator. Our responsibility is to express an opinion on these financial statements and schedules based on our audits. We conducted our audits in accordance with generally accepted auditing standards. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by the Plan administrator, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 1996 and 1995, and the changes in its net assets available for benefits for the year ended December 31, 1996, in conformity with generally accepted accounting principles. Our audits were made for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedules of assets held for investment purposes (Schedule I) and reportable transactions (Schedules II and III) are presented for purposes of additional analysis and are not a required part of the basic financial statements but are supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. The supplemental schedules have been subjected to the auditing procedures applied in the audits of the basic financial statements and, in our opinion, are fairly stated in all material respects in relation to the basic financial statements taken as a whole.

PROFIT SHARING AND RETIREMENT PLAN NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 1996 1. SUMMARY OF SIGNIFICANT PLAN PROVISIONS: The Core Laboratories, Inc. Profit Sharing and Retirement Plan (the "Plan") was established by Core Laboratories, Inc. (the "Company"), effective October 1, 1994. The Plan allows participants to contribute up to 12 percent of their compensation, as defined to the Plan on a pretax basis. The Company contributes to the account of each participant in the Plan up to 4 percent of each participant's compensation, as defined. The Company may, at its discretion, also contribute for a Plan year an additional amount with respect to each participant who has completed one year of service and is employed by the Company on the last day of such Plan year. The Company's board of directors shall determine whether such contribution shall be made for a Plan year, the matching percentage and the percentage of a participant's compensation upon which the match shall be based. Such Company contributions of $383,393 and $329,809 were approved by the board of directors in 1996 and 1995, respectively. The following description of key features of the Plan provide only general information. Participants should refer to the Plan document for a more complete explanation of the Plan's provisions as the Plan document is controlling at all times. PLAN ADMINISTRATOR AND TRUSTEE The Company is the Plan administrator of the Plan as defined under the Employee Retirement Income Security Act of 1974. The Company has contracted with Stone & Associates to maintain the Plan's participant account balances. NationsBank of Texas, N.A. (the "Trustee"), is the trustee of all investments held by the Plan. Effective January 1998, Bankers Trust Company will become the successor trustee. ELIGIBILITY Substantially all of the Company's employees are eligible to participate in the Plan. Participation may commence upon the later of such eligible employee's first day of the calendar quarter coincident with or following the date of hire or the date on which such employees attain the age of 21. VESTING Participants are fully vested in their contributions and related earnings/losses and vest in Company contributions and related earnings/losses at the rate of 20 percent for each year of service. Upon death, physical or mental disability, or normal retirement, participants become fully vested in Company contributions and related earnings/losses. INVESTMENT PROGRAMS Participants have the option of investing their contributions, the Company's matching contributions and any additional Company contributions in any of the following funds (description provided by investment managers). -4- FIDELITY MANAGED INCOME PORTFOLIO--Investments are made in high-quality short- and long-term investment contracts with variable and fixed rates that have maturities of between one and seven years, with the objective of preservation of capital and a low risk level. The average aggregate yield of investments in this portfolio for the year ended September 30, 1996, was 5.98 percent. Investments are stated at contract value which approximates fair value. FIDELITY ASSET MANAGER--Investments are made in domestic and foreign stocks, bonds and short-term instruments with the objective of high return with reduced risk. LONGLEAF PARTNERS FUND--Investments are made in securities of companies having a market capitalization of $1 billion or less with the objective of long-term capital growth. IVY INTERNATIONAL FUND--Investments are made in foreign and domestic equity securities with the objective of long-term capital growth. CORE LABORATORIES N.V. COMMON STOCK FUND--As of January 1, 1996, participants had the option of investing in Core Laboratories N.V. common stock. Investments are in the common stock of the Company purchased at prevailing market prices. Contributions may be invested in one fund or divided among two or more funds. Participants may transfer some or all of the balances out of any fund into one or any combination of the other funds once a quarter. (See Exhibits 1 and 2 for statements of net assets available for benefits, with fund information as of December 31, 1996 and 1995, and statement of changes in net assets available for benefits, with fund information for the year ended December 31, 1996.) ASSET VALUATION The assets of the Plan are recorded at cost in the participants' accounts and converted to market value for financial statement presentation. Pursuant to Department of Labor regulations, the realized gain or loss on the sale of the Plan assets and unrealized appreciation or depreciation of the Plan assets are based on the historical cost of those assets or the cost at the time of purchase, if acquired during the current year. ADMINISTRATIVE EXPENSES The Plan is responsible for its administrative expenses. PRIORITIES UPON PLAN TERMINATION The Company intends for the Plan to be permanent; however, in the event of discontinuance of contributions or termination of the Plan, the total balances of all participants shall become fully vested. LOANS The Plan permits participants to borrow the lesser of $50,000 or 50 percent of their vested account balances in the Plan. These loans bear interest at prime plus 1 percent and are repaid through payroll deductions over a period not to exceed 5 years. WITHDRAWALS AND FORFEITURES A participant may elect to receive benefit payments through any one of the several methods provided by the Plan upon termination, retirement or financial hardship. Participants can withdraw their after-tax contributions in cash without being suspended from making additional contributions to the Plan. -5- Upon termination of employment with the Company, any unvested Company contributions and related earnings/losses are forfeited. Participants returning to the Company within 60 months of their initial termination are entitled to have their previous account balance reinstated by the Company. During 1996 and 1995, $20,381 and $-, respectively, of forfeited balances were utilized to reduce the Company's contributions in the respective years. Hardship withdrawals are allowed in the event of immediate and heavy financial need, subject to Internal Revenue Code (the "Code") provisions. The participants can withdraw up to 100 percent of their pre-tax contributions and are suspended for at least 12 months from making additional contributions to the Plan. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: BASIS OF ACCOUNTING The accounts of the Plan are maintained by the Trustee on the cash basis of accounting. For financial reporting purposes, however, the financial statements have been prepared on the accrual basis of accounting. INVESTMENT VALUATION Plan investments are stated at fair value, as determined by the Trustee, primarily by reference to published market data. USE OF ESTIMATES The preparation of financial statements in conformity with generally accepted accounting principles requires the use of estimates and assumption that affect the accompanying financial statements and disclosures. Actual results could differ from those estimates. 3. TAX STATUS: The Plan obtained its latest determination letter on November 12, 1996, in which the Internal Revenue Service stated that the Plan, as then designed, was in compliance with the applicable requirements of the Code. The Plan has been amended since receiving the determination letter. However, the Company believes that the Plan is currently designed and being operated in compliance with the applicable requirements of the Code. Therefore, they believe that the Plan was qualified and tax-exempt as of the financial statement date. 4. RECONCILIATION OF FORM 5500: Benefits payable to participants, accumulated forfeitures and accrued loan principal reductions are included in net assets available for Plan benefits and are not reflected as a liability in the financial statements. As of December 31, 1996 and 1995, the benefits payable to participants total $265,827 and $233,142, respectively. The following is a reconciliation of net assets available for benefits per the financial statements to the Form 5500 as of December 31, 1996 and 1995: 1996 1995 ------------ ------------ Net assets available for benefits per the financial statements .......................... $ 15,381,845 $ 11,277,179 Less- Current amounts payable to participants at end of year ..........................
