         The solicitation of proxies by the Supervisory Board will be conducted

                                     ITEM 1
                        ELECTION OF SUPERVISORY DIRECTORS


         Our articles of association provide for one or more Supervisory
Directors. Our Supervisory Board currently has seven members who are divided
into three classes of Supervisory Director. Each class is elected for a term of
three years such that the term of one class of Supervisory Director expires at
the annual meeting each year. At this year's annual meeting we will be electing
two Class III Supervisory Directors whose terms expire at the annual meeting.
The Supervisory Board is proposing the election of Richard L. Bergmark and
Alexander Vriesendorp as Class III Supervisory Directors for a term expiring at
the annual meeting in 2006. Both of the nominees for Supervisory Director are
presently members of the Supervisory Board.


                                       1



         Nominees for Supervisory Director are proposed by our Supervisory Board
and elected at the annual meeting by the affirmative vote of a majority of the
votes cast at the meeting. Our shareholders may override the proposal of the
Supervisory Board by a vote of two-thirds of the votes cast at the meeting if
more than one-half of the outstanding share capital is present or represented.

         Unless otherwise instructed or unless authority to vote is withheld,
the enclosed proxy will be voted for the election of the nominees listed above.
If at the time of, or prior to, the annual meeting any of the nominees should be
unable or decline to serve, the discretionary authority provided in the proxy
may be used to vote for a substitute or substitutes designated by our
Supervisory Board. The Supervisory Board has no reason to believe that any
substitute nominees will be required. No proxy will be voted for a greater
number of persons than the number of nominees named herein. Shareholders may not
cumulate their votes in the election of Supervisory Directors.

         THE SUPERVISORY BOARD RECOMMENDS THAT SHAREHOLDERS VOTE "FOR" THE
NOMINEES FOR SUPERVISORY DIRECTOR AS SET FORTH ABOVE, AND PROXIES EXECUTED AND
RETURNED WILL BE SO VOTED UNLESS CONTRARY INSTRUCTIONS ARE INDICATED THEREON.

         The following table sets forth the names, ages and titles of our
Supervisory Directors whose terms expire at the annual meeting and who have been

         o    $500 per meeting for each committee meeting at which the
              individual serves as chairperson; and

         o    reimbursement for all out-of-pocket expenses incurred in attending
              any Supervisory Board or committee meeting.

         Supervisory Directors who are our full-time employees receive no
compensation for serving as Supervisory Directors.

         Our 1995 Nonemployee Director Stock Option Plan, as amended, which we
refer to as the "Nonemployee Director Plan," provides for the issuance of up to
700,000 of our common shares to eligible Supervisory Directors. Under the
Nonemployee Director Plan, each eligible director is generally granted an option
to acquire 1,000 common shares on the date such individual first becomes an
eligible director. In addition, an option to acquire 10,000 common


                                       5



shares will be granted to each nonemployee Supervisory Director (20,000 common
shares if such nonemployee Supervisory Director is the Chairman) each year
generally on the first date in the calendar year set by the Supervisory Board
for the issuance of stock options to more than ten employees under our 1995
Long-Term Incentive Plan, as amended, which we refer to as the "Incentive Plan."
In 2001, the Nonemployee Director Plan was amended to provide that the stock
option grants with respect to the year 2002 would be granted on September 26,
2001. Supervisory Directors who are also our employees receive no grants under
the Nonemployee Director Plan. Options granted will be exercisable for a period
of up to ten years and will vest one year following the date of grant. The
exercise price of options granted under the Nonemployee Director Plan will be
equal to the market price of our common shares on the date of grant.

(1)  During the years ending December 31, 2000, 2001 and 2002, perquisites for
     each individual named in the table above aggregated less than 10% of the
     total annual salary and bonus reported for such individual. Accordingly, no
     such amounts are included in the table.

(2)  As described below under "Executive Compensation Program --- Executive
     Restricted Share Matching Program," on June 1, 2002, Messrs. Demshur,
     Bergmark, Davis and Denson were awarded 47,394, 49,259, 16,492 and 19,708
     restricted shares, respectively, pursuant to an Executive Share Matching
     Restricted Share Agreement. Pursuant to these agreements, the executives
     were awarded a number of restricted shares equal to the number of common
     shares the executives were deemed to have purchased in open market
     transactions (including common shares acquired pursuant to the Core
     Laboratories Profit Sharing and Retirement Plan (which we refer to as the
     "401(k) Plan") or the Core Laboratories Deferred Compensation Plan). The
     restricted shares will generally vest three years from the date of grant
     assuming continued employment, continued ownership of the underlying common
     shares upon which the grant was based and certain other conditions.
     Dividends, if declared, will be paid on the restricted shares prior to
     vesting. The value of the restricted share matching awards included in the
     table above were $649,298, $674,848, $225,940 and $270,000 for Messrs.
     Demshur, Bergmark, Davis and Denson, respectively, and were calculated, as
     required by SEC rules, by multiplying the number of restricted shares
     awarded by the closing price of our unrestricted common shares on the NYSE
     as of June 3, 2002, the first trading day following the award date. As of
     December 31, 2002, the value of these restricted share awards, calculated
     in the same manner, would have been $537,922, $559,090, $187,184 and
     $223,686 for Messrs. Demshur, Bergmark, Davis and Denson, respectively.


                                       6



(3)  On June 1, 2002, Messrs. Demshur, Bergmark, Davis and Denson were awarded
     40,000, 20,000, 20,000 and 10,000 performance restricted shares,
     respectively, which represent the right to receive our common shares in the
     future. None of these awards will vest unless our common shares perform
     better than the common stock of 50% of the companies comprising the Oil
     Services Sector Index (OSX) during the three-year period that began January
     1, 2002. If our common shares perform better than 75% of the companies
     comprising this index during such period, then all of the performance
     restricted shares will vest. If our common shares perform better than
     between 50% and 75% of the companies comprising the index, then an
     interpolated percentage of between 20% and 100% of the performance
     restricted shares will vest at the end of the three-year period. Dividends,
     if declared, will not be paid on the restricted shares prior to vesting.
     The value of the performance restricted share awards included in the table
     above were $580,000, $274,000, $274,000 and $137,000 for Messrs. Demshur,
     Bergmark, Davis and Denson, respectively, and were calculated, as required
     by SEC rules, by multiplying the number of restricted shares awarded by the
     closing price of our unrestricted common shares on the NYSE as of June 3,
     2002, the first trading day following the award date. As of December 31,
     2002, the value of these restricted share awards, calculated in the same
     manner, would have been $454,000, $227,000, $227,000 and $113,500 for
     Messrs. Demshur, Bergmark, Davis and Denson, respectively.

(4)  Consists of matching contributions and contributions by our company through
     our retirement plans, amounts paid under certain insurance plans and a
     transportation allowance.

         David M. Demshur Employment Agreement. Mr. Demshur serves as our
President and Chief Executive Officer pursuant to an employment agreement that
is currently set to expire in 2006. Unless either party gives notice to

         o    the provision of a benefits package for Mr. Demshur and his
              dependants which includes medical, hospital, dental, disability
              and life insurance plans and coverage at least as favorable as
              those provided immediately prior to the termination for as long as
              Mr. Demshur and his dependents are living;

         o    the payment of a lump sum amount equal to the non-vested employer
              contributions allocated to his account under our 401(k) Plan that
              are forfeited as a result of the termination;

         o    the full and immediate vesting of all of his outstanding stock
              options which options shall remain exercisable for a period of
              three months following such termination; and

              change in control; and

         o    three times the higher of (A) 45% of the maximum annual incentive
              bonus he could have earned pursuant to his employment contract or
              (B) the highest annual bonus he received in the three years prior
              to the change of control.

         Additionally, if any of the payments or benefits described above would
be subject to the excise tax imposed by Section 4999 of the Internal Revenue
Code of 1986, as amended, then Mr. Demshur will be entitled to receive a
gross-up payment equal the amount of excise tax imposed plus all taxes imposed
on the gross-up payment.

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

         Section 16(a) of the Exchange Act requires the Supervisory Directors,
executive officers and persons who own more than ten percent of our common
shares to file initial reports of ownership and reports of changes in ownership
(Forms 3, 4 and 5) of our common shares with the SEC and the NYSE. Supervisory
Directors, executive officers and greater than ten percent shareholders are
required by SEC regulations to furnish us with copies of all such forms that
they file.

         To our knowledge, based upon our review of the Section 16(a) filings
that have been received by us, we believe that during the fiscal year ending
December 31, 2002, our Supervisory Directors, executive officers and ten percent
shareholders complied with the applicable Section 16(a) filing requirements.

COMMITTEES OF THE SUPERVISORY BOARD

         The Supervisory Board has three standing committees, the identities,
memberships and functions of which are described below:

         Audit Committee. The current members of the Audit Committee of our
Supervisory Board are Messrs. Joyce, Ogren and Perna. The Audit Committee's
principal functions include making recommendations concerning the engagement of
the independent accountants, reviewing with the independent accountants the plan
and results of the auditing engagement, approving professional services provided
by the independent accountants and reviewing the adequacy of our internal
accounting controls. Each member of the Audit Committee is independent as
defined by the corporate governance standards of the New York Stock Exchange.
The Supervisory Board has developed a written charter for our audit committee
which was filed as an appendix to our proxy statement in 2001.

         Compensation Committee. The current members of the Compensation
Committee of our Supervisory Board are Messrs. Ogren and Perna. The Compensation
Committee's principal functions include a general review of our compensation and

objectives. The Compensation Committee reviews and approves the Chief Executive
Officer's recommendations on the compensation of our senior executive officers,
granting of awards under our stock option and other benefit plans and adopting
and changing major compensation policies and practices.


                                       9



         In addition to establishing the compensation for the Chief Executive
Officer, the Compensation Committee reports its recommendations to the whole
Supervisory Board for approval. The Compensation Committee also oversees our
Incentive Plan and our Nonemployee Director Plan.

         Nominating and Governance Committee. On November 12, 2002, the
Supervisory Board established a Nominating and Governance Committee of the
Supervisory Board. The current members of the Nominating and Governance
Committee are Messrs. Joyce, Ogren, Schouten and Vriesendorp. The Nominating and
Governance Committee's principal functions include recommending candidates to
the full board for election or appointment as Supervisory Director and advising
about, and recommending to the Supervisory Board, an appropriate set of
corporate governance practices. Each member of the Nominating and Governance
Committee is independent as defined by the corporate governance standards of the
New York Stock Exchange.

         The Supervisory Board held five meetings in 2002, the Audit Committee
held eight meetings in 2002, the Compensation Committee held one meeting in 2002
and the Nominating and Governance Committee held no meetings in 2002. Each
Supervisory Director attended at least 75% of the meetings of the Supervisory
Board and of all committees on which he serves.

REPORT OF THE COMPENSATION COMMITTEE ON EXECUTIVE COMPENSATION

         The Compensation Committee's responsibilities are:

         o    to oversee the development of the compensation program for our
              officers and managerial employees;

         o    to administer the incentive and stock option plans, including
              approval of grants and awards under these plans; and

         o    to establish the compensation program for our Chief Executive
              Officer and our other executive officers.

Our Compensation Committee is comprised of Joseph R. Perna and D. John Ogren,
neither of whom are our employees.

         Executive Compensation Philosophy. The objective of the compensation
program for officers and managers is to create strong financial incentives for
corporate and division officers and managers to increase profits, revenues and
operating efficiency, which we expect to lead to an increase in shareholder
value. The following objectives guide the Compensation Committee in its
deliberations:

         o    provide a competitive compensation program that enables us to
              attract and retain key executives and Supervisory Board members;

         o    ensure a strong relationship between our performance results and
              those of our divisions and the total compensation received by an
              individual;


                                       10



         o    balance our annual and longer term performance objectives;

         o    encourage executives to acquire and retain meaningful levels of
              common shares; and

         o    work closely with our Chief Executive Officer to ensure that the
              compensation program supports our management style, objectives and
              culture.

         In addition to normal employee benefits, the executive total
compensation program includes base salary, annual cash incentive compensation
and longer term stock-based grants and awards.

         Market Comparisons. Primary market comparisons for executive
compensation are made to other oilfield service companies, adjusted for size and
job responsibilities. The companies used for market comparisons in the
development of the compensation program are broader than those used in the
performance graph presented elsewhere in this proxy statement and are used
because they are more representative of the market in which we compete for
executive talent. Data sources include peer company proxy disclosures, oilfield
industry surveys, national survey databases and general trend data provided by
consultants.

         Variable Incentives. Variable incentives, both annual and longer term,
are major components of the program and are used to link pay with performance
results appropriate to each executive officer or manager. Variable incentive
awards and performance objectives are calibrated such that total compensation
will approximate the market 50th percentile when our performance plans are
achieved and exceed the 50th percentile when our performance plans are exceeded.

         Internal Revenue Code Section 162(m). Internal Revenue Code Section
162(m) imposes a $1,000,000 limit, with certain exceptions, on the deductibility
of compensation paid to each of our five highest paid executive officers. In
particular, compensation that is determined to be "performance based" is exempt
from this limitation. To be "performance based," incentive payments must use
predetermined objective standards, limit the use of discretion in making awards
and be certified by the Compensation Committee made up of "outside directors."
To date, we have not lost any tax deductions related to the limitations of
Section 162(m). The Compensation Committee will continue to monitor these issues
and will take appropriate action if it is warranted in the future.

EXECUTIVE COMPENSATION PROGRAM

         The following is a discussion of each of the principal components of
the executive total compensation program.

         Base Salary. The base salary program targets the median of the primary
comparison group for corporate and divisional officers and managers. Each
executive is reviewed individually on an annual basis. Salary adjustments are
based on the individual's experience and background, the individual's
performance during the prior year, the general movement of salaries in the
marketplace and our financial position. As a result of these factors, an
executive's base salary may be above or below the targeted median at any point
in time.

         Annual Incentive Compensation. We administer an annual incentive plan
for our corporate and divisional officers and managers. The goal of the plan is
to reward participants in proportion to our performance as a whole, the
performance of the division for which they have direct responsibility and their
individual contributions to our success.

         For 2002, corporate participants were measured on earnings before
interest and taxes, or "EBIT," and earnings per share, while division
participants were also measured on working capital management. In addition, a
discretionary component was included as part of the plan so that outstanding
effort and dedication could be recognized. The measures were weighted
substantially equally.

         Supplemental Executive Retirement Plans. In 1998, we adopted the Core
Laboratories Supplemental Executive Retirement Plan, which we refer to as the
"Group SERP," for the benefit of certain key employees and outside directors.
The Group SERP was established to provide additional retirement income to the
participants and death benefits to the participants' designated beneficiaries as
a reward for the participants' contributions to our success and growth. The four
participants in the Group SERP are Richard L. Bergmark, David M. Demshur, Joseph
R. Perna and Stephen D. Weinroth.


                                       11



Mr. Weinroth served as Chairman of our Supervisory Board until May 2001. Each
participant is entitled to receive a retirement benefit of $250,000 per year,
which begins on the participant's retirement date and is paid in annual
installments until the participant's death. If a participant dies on or after
his retirement date and prior to receiving 15 annual installments of his
retirement benefit, then the participant's designated beneficiary is entitled to
receive $250,000 each year until such payments have been made for an aggregate
of 15 years to both the participant and such designated beneficiary. If the
participant dies before his retirement date, the designated beneficiary of the
deceased participant is entitled to receive $225,000 each year for 15 years.
Each participant's benefit under the Group SERP is fully vested and fully
accrued. Additionally, the participant may make a prior election to receive a
lump sum payment upon a "change of control" of our company equal to the
discounted present value of the retirement benefits that would have been paid
upon the participant's retirement. Benefits under the Group SERP may be
forfeited only in the event of a participant's termination for cause.

         In 1999, we adopted the Core Laboratories Supplemental Executive
Retirement Plans for Monty L. Davis and John D. Denson, which we refer to as the
"Individual SERPs." The Individual SERPs were established to provide additional
retirement income for Messrs. Davis and Denson and death benefits for their
designated beneficiaries as a reward for their respective contributions to our
success and growth. Each is entitled to receive a retirement benefit commencing
on his retirement date. The amount of the retirement benefit is determined using
a formula that takes into consideration the participant's compensation, years of
employment, and a five year vesting schedule, and is paid in annual installments
until the participant's death. Vesting in this retirement benefit is accelerated
upon a "change in control" of our company. If a participant dies on or after his
retirement date and prior to receiving 15 annual installments of his retirement
benefit, then the designated beneficiary of the deceased participant is entitled
to receive the payments the deceased participant would have received if the
participant's death had not occurred. Such payments will continue until payments
for an aggregate of 15 years have been made to both the participant and his
designated beneficiary. If a participant dies prior to his retirement date, the
designated beneficiary of the deceased participant is entitled to receive annual
payments for 15 years, and the amount of such payments is determined using a
formula similar to that described above. Additionally, the participant may make
a prior election to receive a lump sum payment upon a "change of control" of our
company equal to the discounted present value of the retirement benefits that
would have been paid upon the participant's retirement. Benefits under an
Individual SERP may be forfeited upon a participant's termination for cause.

         We have purchased insurance coverage on the lives of Messrs. Bergmark,
Demshur, Perna, Davis and Denson to assist us in providing benefits under the
Group and Individual SERPs. We are the owner and beneficiary of the insurance
coverage and are obligated to pay the total premium of $319,500 and $82,191 each
year for the Group SERP and the Individual SERPs, respectively, until the
policies are paid up (which we anticipate will occur in 2005). Based on
actuarial calculations (including a 12% earnings rate assumption), we expect
that the death benefits paid to us under the insurance policies will be
sufficient to cover the costs of the Group and Individual SERPs' benefits and
the policy premium payments for these individuals. However, to the extent the
death benefits under the policies are insufficient to cover those costs, we are
obligated to pay the remainder out of our other general assets to absorb any
shortfall. In the event of a "change of control," we are obligated to fully fund
the amount of the retirement benefits and death benefits of all six participants
in the Group and Individual SERPs and their designated beneficiaries. The amount
of the "change of control" contribution is the lesser of the total amount due
under the terms of the Group and Individual SERPs and the amount of unpaid
premiums on any insurance policies held by the trust through the seventh
anniversary of the date of the purchase of each such policy.

         Deferred Compensation Plan. Core Laboratories LP, one of our principal
subsidiaries, has adopted a deferred compensation plan that allows certain
officers, including all of our executive officers, to defer a portion of their
salary and bonus, as well as the amount of any reductions in their deferrals
under the 401(k) Plan, due to certain limitations imposed by the Internal
Revenue Code of 1986, as amended. The 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. These employer contributions vest
gradually over a period of five years. Discretionary employer contributions may
also be made on behalf of participants in the plan and are subject to
discretionary vesting schedules determined at the time of such contributions.
Vesting in all employer contributions is accelerated upon the death of the
participant or a "change in control." Employer contributions under the plan are
forfeited upon a participant's termination of employment to the extent they are
not vested at that time.


                                       12



         Stock Based Compensation. Stock ownership by corporate and divisional
management is encouraged through the use of the Incentive Plan which provides
for the award of our common shares and options to buy our common shares. The
Compensation Committee and management believe that widespread common share
ownership by key employees is an important means of encouraging superior
performance and employee retention. Common share option grants are considered
annually based on competitive multiples of base salary. Senior executives
typically have a higher multiple and, as a result, have a greater portion of
their total compensation linked to our long-term success. In determining the
appropriate grant multiples, we target the market median among publicly-held
oilfield service companies of similar size. In 2002, our executive officers did
not receive stock option grants.

         In 2002, we made performance restricted share awards to members of our
corporate and divisional management, including our executive officers. These
performance restricted share awards represent the right to receive our common
shares in the future. Assuming the employee's continued employment (or death or
disability while employed), these awards will vest on December 31, 2004 based on
the performance of our common shares as compared to that of the common stock of
the companies comprising the Oil Service Sector Index (OSX). None of these
awards will vest unless our common shares perform better than the common stock
of 50% of the companies comprising this index during the three-year period that
began on January 1, 2002. If our common shares perform better than 75% of the
companies comprising the index during such period, then all of the performance
restricted shares will vest. If our common shares perform better than between
50% and 75% of the companies comprising the index, then an interpolated
percentage of between 20% and 100% of the performance restricted shares will
vest at the end of the three-year period. Upon a "change in control" of our
company, all of the performance restricted shares will vest.

         Executive Restricted Share Matching Program. In 2002, we implemented an
Executive Restricted Share Matching Program to encourage personal investment in
our common shares by our executive officers. Under the program, Messrs. Demshur,
Bergmark, Davis and Denson were granted a number of restricted shares equal to
the number of common shares such executive officer had purchased in open market
transactions or held in his deferred compensation, 401(k) or other retirement
account as of June 1, 2002. The number of shares that an executive officer was
eligible to have matched was capped at 50,000 shares. Pursuant to the program,
Messrs. Demshur, Bergmark, Davis and Denson were awarded 47,394, 49,259, 16,491
and 19,708 restricted shares, respectively. The shares will vest three years
from the date of grant assuming the executive's continued employment with our
company and continued ownership of the underlying common shares upon which the
grant was based. These awards will also vest immediately upon the death or
disability of the participant, his involuntary termination without cause or a
"change in control" of our company.

         The agreements governing the awards also provide that each executive
officer is entitled to receive an additional restricted share award upon the
vesting of the initial restricted shares in order to reimburse the executive for
the amount of tax payable by the executive upon the vesting of the initial
restricted shares (including any tax due as a result of the tax gross-up
itself). If the initial restricted shares vest as a result of any of the events
listed in the last sentence of the preceding paragraph, the executive will be
granted a lump sum cash payment equal to the amount of tax due (including any
tax due as a result of the tax gross-up itself) rather than a grant of
restricted shares. The additional restricted shares will vest two years from the
date of the grant assuming the executive's continued employment with our
company, continued ownership of the common shares upon which the initial grant
was based and continued ownership of the vested initial restricted shares (less
a number of restricted shares equal in value to the amount of tax the executive
was required to pay upon the vesting of the initial restricted shares). These
additional awards will also vest immediately upon the death or disability of the
participant, his involuntary termination without cause or a "change in control"
of our company

COMPENSATION OF THE CHIEF EXECUTIVE OFFICER

         Our Chief Executive Officer, David M. Demshur, participates in the
executive compensation program described above. In establishing the base salary
for Mr. Demshur, our Compensation Committee assessed the pay levels for chief
executive officers in similar companies in the oilfield service industry and our
profit performance. In 2002, Mr. Demshur's base salary was $447,923. He received
no stock options in 2002 and did not receive an annual incentive award for 2002.
Mr. Demshur received an award of 40,000 performance restricted shares in 2002
and a grant of 47,394 restricted shares pursuant to the Executive Restricted
Share Matching Program described above.

         Submitted by the Compensation Committee of the Board of Supervisory
Directors.

FISCAL 2002 AUDIT FEE SUMMARY

         Set forth below is a summary of the total fees paid to our independent
public accountants, PricewaterhouseCoopers LLP, for fiscal 2002. These fees
consisted of:

         Audit Fees............................................  $  1,438,485
         Financial Information Systems Design
           and Implementation Fees.............................           ---
         All Other Fees........................................        86,376
                                                                 ------------
              Total............................................  $  1,524,861

         In determining the independence of PricewaterhouseCoopers LLP for
purposes of its 2002 audit, the Audit Committee considered whether the rendering
of non-audit services was compatible with maintaining PricewaterhouseCoopers
LLP's independence and concluded that PricewaterhouseCoopers LLP's independence
was not compromised by the provision of such services.

SHAREHOLDER RETURN PERFORMANCE PRESENTATION

         The following performance graph compares the performance of our common
shares to the Standard & Poor's 500 Index and the Standard & Poor's Oil Well
Equipment and Services Index (which has been selected as our peer group) for the
period beginning January 1, 1998 and ending December 31, 2002. The graph assumes
that the value of the investment in our common shares and each index was $100 at
January 1, 1998 and that all dividends were reinvested. Our common shares began
trading on the Nasdaq Stock Market in September 1995 and in July 1998 ceased
trading on the Nasdaq Stock Market and began trading on the New York Stock
Exchange.

CHANGE IN INDEPENDENT PUBLIC ACCOUNTANTS

         On April 10, 2002, our Supervisory Board, upon the recommendation of
our Audit Committee, made a determination to dismiss Arthur Andersen LLP as our
independent public accountants and selected PricewaterhouseCoopers LLP to serve
as our independent public accountants for the fiscal year ending December 31,
2002.

         Arthur Andersen LLP's reports on our consolidated financial statements
for each of the years ended December 31, 2001 and 2000 did not contain an
adverse opinion or disclaimer of opinion, nor were they qualified or modified as
to the uncertainty, audit scope or accounting principles. Arthur Andersen LLP's
reports on our consolidated financial statements for the year ended December 31,
2001 were filed with our Annual Report on Form 10-K for the year ended December
31,2001.

         During the years ended December 31, 2001 and 2000 and through the end
of the period during which they served as our independent public accountants,
there were no disagreements with Arthur Andersen LLP on any matter of accounting
principles or practices, financial statement disclosure, or auditing scope or
procedure which, if not resolved to Arthur Andersen LLP's satisfaction, would
have caused them to make reference to the subject matter in connection with
their report on our consolidated financial statements for such years. There were
no reportable events as listed in Item 304(a)(1)(v) of Regulation S-K.

         During the years ended December 31, 2001 and 2000 and through the date
of their engagement as our independent public accountants in April 2002, we did
not consult PricewaterhouseCoopers LLP with respect to the application of
accounting principles to a specified transaction, either completed or proposed,
or the type of audit opinion that might be rendered in our consolidated
financial statements, or any other matters or reportable events as set forth in
Items 304(a)(2)(i) and (ii) of Regulation S-K.

                                     ITEM 2.
                           APPROVAL OF ANNUAL ACCOUNTS

         At the annual meeting, our shareholders will be asked to approve our
Dutch Statutory Annual Accounts for the fiscal year ending December 31, 2002, as
required under Dutch law and our articles of association. In accordance with


                                       15



Article 408 of the Dutch Civil Code, the Annual Accounts are our annual accounts
and our participation and do not represent the consolidated accounts of our
company and subsidiaries as presented in our Consolidated Financial Statements
contained in our Annual Report for the year ending December 31, 2002.

         The affirmative vote of the majority of the votes cast at the annual
meeting is required to adopt the Annual Accounts.

         THE SUPERVISORY BOARD RECOMMENDS THAT SHAREHOLDERS VOTE "FOR" THE
ADOPTION OF THE ANNUAL ACCOUNTS, AND PROXIES EXECUTED AND RETURNED WILL BE SO

                                     ITEM 3.
                EXTENSION OF AUTHORITY OF MANAGEMENT BOARD UNTIL
                     NOVEMBER __, 2004 TO REPURCHASE SHARES

         Under Dutch law, our articles of association and subject to certain
Dutch statutory provisions, we may repurchase up to 10% of our outstanding share
capital in open market purchases at any price that does not exceed $200.00 per
share or its equivalent in other currencies. This $200.00 limit is an arbitrary
number used to satisfy Dutch statutory provisions and our articles of
association and is not reflective of the price that would actually be paid in
any such repurchase unless the market price of our common shares approximated
such amount on the date of repurchase. Any such purchases are subject to the
approval of the Supervisory Board and the authorization of our shareholders at
the annual meeting, which authorization must be renewed every 18 months. In
connection with our initial public offering in September 1995, our shareholders
authorized our Management Board to make such repurchases for a period of 18
months. At each annual meeting subsequent to 1995, our shareholders have
extended the period such that the current period is set to expire on November
29, 2003. In 2002, we repurchased approximately 860,400 of our common shares for
an aggregate purchase price of approximately $9.0 million. In 2003 through March
31, we have repurchased approximately 790,800 of our common shares for an
aggregate purchase price of $8.9 million. We believe that it is in the best
interest of our company and shareholders to have the flexibility to repurchase
shares in the future if the Supervisory Board deems it advisable to do so. THIS
AUTHORITY IS SIMILAR TO THAT GENERALLY AFFORDED UNDER STATE LAW TO PUBLIC
COMPANIES DOMICILED IN THE UNITED STATES.

         At the annual meeting, our shareholders will be asked to approve a
further extension of this authority for an additional 18-month period from the
date of the annual meeting until November __, 2004.

         The affirmative vote of the majority of the votes cast at the annual
meeting is required to extend the authorization of the management board to
repurchase up to 10% of our outstanding share capital for an additional 18-month
period from the date of the annual meeting.

         THE SUPERVISORY BOARD RECOMMENDS THAT SHAREHOLDERS VOTE "FOR" THE
EXTENSION OF THE AUTHORITY OF THE MANAGEMENT BOARD TO REPURCHASE UP TO 10% OF
OUR OUTSTANDING SHARE CAPITAL UNTIL NOVEMBER __, 2004 AT A PRICE NOT TO EXCEED
$200.00 PER SHARE, AND PROXIES EXECUTED AND RETURNED WILL BE SO VOTED UNLESS
CONTRARY INSTRUCTIONS ARE INDICATED THEREON.

                                     ITEM 4.
                   EXTENSION OF AUTHORITY OF SUPERVISORY BOARD
          TO ISSUE SHARES OF CORE LABORATORIES N.V. UNTIL MAY __, 2008

         Under Dutch law and our articles of association, the Supervisory Board
has the power to issue shares of our share capital as long as the Supervisory
Board has been designated and authorized by the shareholders to do so at the
annual meeting. An authorization of the Supervisory Board to issue shares may be
effective for a period of up to five years and may be renewed on an annual
rolling basis. In connection with our initial public offering in September 1995,
our shareholders authorized the Supervisory Board to issue shares and/or rights
with respect to our shares for a five-year period. At each annual meeting
subsequent to 1995, our shareholders have extended the period such that the
current period is set to expire on May 29, 2007.


                                       16



         At the annual meeting, our shareholders will be asked to approve a
further extension of this authority for a five-year period from the date of the
annual meeting until May __, 2008. THIS AUTHORITY TO ISSUE SHARES IS SIMILAR TO
THAT GENERALLY AFFORDED UNDER STATE LAW TO PUBLIC COMPANIES DOMICILED IN THE
UNITED STATES. Management believes that retaining the flexibility to issue
shares for acquisition, financing or other business purposes in a timely manner
without first obtaining specific shareholder approval is important to our
continued growth. Furthermore, our common shares are listed on the NYSE and,
accordingly, the issuance of additional shares will remain subject to the rules
of the NYSE. In particular, the NYSE requires shareholder approval for the
issuance of shares of common stock in excess of twenty percent of the shares
outstanding except for public offerings for cash or bona fide private offerings
at a price greater than both the book and market value of a company's common
stock.

         The affirmative vote of the majority of the votes cast at the annual
meeting is required to extend the authority of the Supervisory Board to issue
and/or to grant rights (including options to purchase) with respect to our
common and/or preference shares for a five-year period from the date of the
annual meeting.

         THE SUPERVISORY BOARD RECOMMENDS THAT SHAREHOLDERS VOTE "FOR" THE
EXTENSION OF THE AUTHORITY OF THE SUPERVISORY BOARD TO ISSUE AND/OR TO GRANT
RIGHTS (INCLUDING OPTIONS TO PURCHASE) WITH RESPECT TO OUR COMMON AND/OR
PREFERENCE SHARES UNTIL MAY __, 2008, AND PROXIES EXECUTED AND RETURNED WILL BE
SO VOTED UNLESS CONTRARY INSTRUCTIONS ARE INDICATED THEREON.

                                     ITEM 5.
                   EXTENSION OF AUTHORITY OF SUPERVISORY BOARD
           TO LIMIT OR ELIMINATE PREEMPTIVE RIGHTS UNTIL MAY __, 2008

         Holders of our common shares (other than our employees and employees of
our subsidiaries who are issued common shares pursuant to the exercise of
options granted under the Incentive Plan and the Nonemployee Director Plan) have
a pro rata preemptive right of subscription to any of our common shares issued
for cash unless such right is limited or eliminated by our Supervisory Board.
Holders of our common shares have no pro rata preemptive subscription right with
respect to any common shares issued for consideration other than cash. If
designated and authorized by our shareholders at the annual meeting, the
Supervisory Board has the power to limit or eliminate such rights. Such an
authorization may be effective for up to five years and may be renewed for
successive five-year periods. In connection with our initial public offering in
September 1995, our shareholders authorized the Supervisory Board to limit or
eliminate the preemptive rights of holders of our common shares for a five-year
period. At each annual meeting subsequent to 1995, our shareholders have
extended this period such that the current period is set to expire on May 29,
2007.

         At the annual meeting, our shareholders will be asked to approve a
further extension of this authority for a five-year period from the date of the
annual meeting until May __, 2008 to limit or eliminate preemptive rights.
PREEMPTIVE RIGHTS ARE UNCOMMON FOR PUBLIC COMPANIES DOMICILED IN THE UNITED
STATES. Management believes that if the Supervisory Board is not granted the
authority to limit preemptive rights, the ability of our company to engage in
equity financing transactions would be significantly affected. Furthermore, as
long as our common shares remain listed on the NYSE, any issuance of common
shares will remain subject to the rules of the NYSE, including limitations on
our ability to issue shares without shareholder approval. See Item 4 above for a
discussion of the NYSE rules regarding stock issuances.

         The affirmative vote of the majority of the votes cast at the annual
meeting is required to extend the authority of the Supervisory Board to limit or
eliminate the preemptive rights of holders of our common shares for a five-year
period from the date of the annual meeting.

         THE SUPERVISORY BOARD RECOMMENDS THAT SHAREHOLDERS VOTE "FOR" THE
EXTENSION OF THE AUTHORITY OF THE SUPERVISORY BOARD TO LIMIT OR ELIMINATE
PREEMPTIVE RIGHTS OF HOLDERS OF OUR COMMON SHARES UNTIL MAY __, 2008, AND
PROXIES EXECUTED AND RETURNED WILL BE SO VOTED UNLESS CONTRARY INSTRUCTIONS ARE
INDICATED THEREON.

                                     ITEM 6
            RATIFICATION OF APPOINTMENT OF PRICEWATERHOUSECOOPERS LLP
            AS INDEPENDENT PUBLIC ACCOUNTANTS OF THE COMPANY FOR 2003


                                       17



         The Supervisory Board has appointed the firm of PricewaterhouseCoopers
LLP as our independent public accountants for the year ending December 31, 2003
subject to ratification by our shareholders. PricewaterhouseCoopers LLP has
acted as our independent public accountants since April 2002.

         The affirmative vote of the majority of the votes cast at the annual
meeting is required to ratify the appointment of PricewaterhouseCoopers LLP as
our independent public accountants for 2003.

         In the event the appointment is not ratified, our Supervisory Board
will consider the appointment of other independent accountants. Our Supervisory
Board may terminate the appointment of PricewaterhouseCoopers LLP as our
independent accountants without the approval of our shareholders whenever our
Supervisory Board deems such termination necessary or appropriate.
Representatives of PricewaterhouseCoopers LLP are not expected to be present at
the annual meeting.

         THE SUPERVISORY BOARD RECOMMENDS THAT THE SHAREHOLDERS VOTE "FOR" THE
RATIFICATION OF PRICEWATERHOUSECOOPERS' APPOINTMENT AS OUR INDEPENDENT PUBLIC
ACCOUNTANTS FOR 2003 AND PROXIES EXECUTED AND RETURNED WILL BE SO VOTED UNLESS
CONTRARY INSTRUCTIONS ARE INDICATED THEREON.

                                     ITEM 7.
                                  OTHER MATTERS

         The Supervisory Board does not know of any other matters that are to be
presented for action at the annual meeting. However, if any other matters
properly come before the annual meeting or any adjournment thereof, it is
intended that the enclosed proxy will be voted in accordance with the judgment
