                     SOLICITATION AND REVOCATION OF PROXIES

         The accompanying proxy is being solicited by and on behalf of the Board
of Supervisory Directors of Core Laboratories N.V. for use at our 2002 annual

statement. Any shareholder giving a proxy has the power to revoke it by oral or
written notice to our corporate Secretary at any time before the proxy is voted.

         The solicitation of proxies by the Supervisory Board will be conducted
by mail. In addition, certain members of the Supervisory Board, officers and
regular employees of our company may solicit proxies in person, by facsimile or

outstanding and entitled to notice of and to vote at the annual meeting. The
presence, in person or by proxy, of at least a majority of our outstanding

articles of association, common shares abstaining from voting and broker
non-votes will not count as votes cast at the annual meeting but will count for

                                     ITEM 1
                        ELECTION OF SUPERVISORY DIRECTORS

         Our articles of association provide for one or more Supervisory
Directors. Nominees for Supervisory Director are proposed by the Supervisory
Board and elected at each annual meeting of shareholders 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. The Supervisory Board is divided into Classes I, II and III, the
terms of office of which are scheduled to expire on the dates of the annual
meeting of shareholders in 2004, 2003 and 2002, respectively.

         The Supervisory Board is proposing the election of eight Supervisory
Directors at the annual meeting. Three of the nominees (David M. Demshur, Rene
R. Joyce and Jacobus Schouten) will be elected as Class I Supervisory Directors
for a term expiring 2005, three of the nominees (D. John Ogren, Joseph R. Perna
and Timothy J. Probert) will be elected

                                       1


as Class II Supervisory Directors for a
term expiring 2004 and two of the nominees (Richard L. Bergmark and Alexander
Vriesendorp) will be elected as Class III Supervisory Directors for a term
expiring 2003. At each of our future annual meetings, the successors to the
class of Supervisory Directors whose terms shall expire that year shall be
elected to hold office for a term of three years and until their respective
successors shall have been duly elected and qualified. All of the nominees for
Supervisory Directors are presently members of the Supervisory Board.

         Unless otherwise instructed or unless authority to vote is withheld,
the enclosed proxy will be voted for the election of the nominees listed below.
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 the
Supervisory Board. The Supervisory Board has no reason to believe that any
substitute nominee or 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 the
persons who have been nominated for election as Supervisory Directors:

(5)  Mr. Agnew is not standing for re-election to the Board of Supervisory
     Directors as the Dutch Civil Code requires that a supervisory director
     resign no later than the day of the annual meeting held during the year in
     which the supervisory director turns 72 years of age.

Committees of the Supervisory Board

         The Supervisory Board has two 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. Agnew, Joyce, Ogren and Perna; however, Mr. Agnew
is not standing for re-election to the Board of Supervisory Directors. 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.

         Compensation Committee. The members of the Compensation Committee of
our Supervisory Board are Messrs. Joyce, Perna and Probert. The Compensation
Committee's functions include a general review of our compensation and benefit
plans to ensure that they are properly designed to meet corporate 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.

         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
1995 Long-Term Incentive Plan, as amended, which we refer to as the "Incentive
Plan," and our 1995 Nonemployee Directors Stock Option Plan, as amended, which
we refer to as the "Nonemployee Director Plan."

         The Supervisory Board held four meetings in 2001, the Audit Committee
held four meetings in 2001 and the Compensation Committee held two meetings in
2001. Each Supervisory Director attended at least 75% of the meetings of the
Supervisory Board and of all committees on which he serves. The Supervisory
Board does not have a nominating committee.

Director Compensation

         Each Supervisory Director who is not our full-time employee is paid:

o        an annual retainer of $24,000, payable semiannually in arrears;

o        $1,000 per meeting of the Supervisory Board at which the individual
         is present in person;

o        $750 per meeting for each committee meeting at which the individual
         is present in person;

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

                                        6



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.

         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 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 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 the common shares on the date of grant.

(1)  The dollar amounts under these columns represent the potential realizable
     value of each grant of options assuming that the market price of Common
     Shares appreciates in value from the date of grant at the 5% and 10% annual
     rates prescribed by the Securities and Exchange Commission and therefore is
     not intended to forecast possible future appreciation, if any, of the price
     of our Common Shares.

(1)  Computed based on the difference between aggregate fair market value and
     aggregate exercise price. The fair market value of our common shares on
     December 31, 2001 was based on the average of the high and low sales prices
     on the NYSE on such date.

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, 2001, our Supervisory Directors, executive officers and ten percent
shareholders complied with the applicable Section 16(a) filing requirements.

Compensation Committee Interlocks and Insider Participation

         During 2001, no executive officer served as:

o        a member of the compensation committee (or other board committee
         performing equivalent functions or, in the absence of any such
         committee, the entire board of directors) of another entity, one of
         whose executive officers served as one of our Supervisory Directors; or

o        a director of another entity, one of whose executive officers served on
         our Supervisory Board or the board of directors of one of our
         subsidiaries.

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.

During 2001, our  Compensation  Committee was comprised of the following
Supervisory  Directors,  none of whom are our employees:  Rene R. Joyce,
Joseph R. Perna and Timothy J. Probert.

         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;

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.

                                       9


         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 2001, 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. We have 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. 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. Benefits under the Group
SERP may be forfeited only in the event of a participant's termination for
cause.

         We have also 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

                                       10


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. 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 ERPs, respectively, until the
policies are paid up (which we anticipate will occur in 2005). Based on
actuarial calculations (including a 12% interest 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 ndividual 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 Core Laboratories Profit Sharing and Retirement Plan, which we refer
to as 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.

         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 longer term success. In determining the
appropriate grant multiples, we target the market median among publicly-held
oilfield service companies of similar size. In 2002, we expect to begin making
performance restricted stock awards to members of our corporate and divisional
management. Assuming the employee's continued employment, these awards will vest
at the end of three years based on the performance of our common stock as
compared to that of the companies comprising the Oil Field Services Index (OSX).
None of these restricted stock awards will vest unless our common shares perform
better than the common stock of one half of the companies comprising this index
during the three year period. These awards will vest immediately upon a "change
in control." Additionally, certain of our divisional and corporate management
will receive their annual incentive compensation award in the form of a
restricted stock grant. These restricted shares will vest 50% at the end of two
years and the remaining 50% at the end of three years assuming the employee's
continued employment. These awards will also vest immediately upon the death or
disability of the participant or a "change in control." Finally, it is expected
that on May 15, 2002, Messrs. Demshur, Bergmark, Davis and Denson will be
granted a number of shares of restricted stock equal to the number of common
shares such executive officer has purchased on the open market or holds in a
deferred compensation, 401(k) or other retirement account. The number of shares
that an executive officer may be granted will not exceed 50,000 shares. The
shares will vest at the end of three years assuming the executive's continued

                                       11


employment with our company and 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." The awards will also provide that each executive
officer will be entitled to receive an interest-free loan to pay any taxes that
are due upon the vesting of the restricted stock. This loan will be conditioned
on, among other things, the executive agreeing to retain the newly vested
restricted shares and the underlying common shares for an additional two-year
period. The loan will become due if the executive were to sell any of his
underlying common shares, voluntarily terminate his employment or have his
employment terminated with cause prior to the end of the two year holding
period. At the end of the two year holding period, the loan will be forgiven and
the company will make a gross-up payment to the executive in an amount equal to
any tax that becomes due as a result of the loan forgiveness and the gross-up
payment.

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 2001, Mr.  Demshur's base salary was $420,000.  He did
not receive an annual incentive award for 2001.  Mr. Demshur received 250,000
stock options in 2001.

Report of the Audit Committee

         The Audit Committee has reviewed and discussed with management Core
Laboratories' audited financial statements as of and for the year ended December
31, 2001.

         The Audit Committee has discussed with the independent auditors the
matters required to be discussed by Statements on Auditing Standards No. 61,
Communication with Audit Committees, as amended, by the Auditing Standards Board
of the American Institute of Certified Public Accountants.

         The Audit Committee has received and reviewed the written disclosures
and the letter from the independent auditors required by Independence Standard
No. 1, Independence Discussions with Audit Committees, as amended, by the
Independence Standards Board, and has discussed with the auditors the auditors'
independence.

         Based on the reviews and discussions referred to above, the Audit
Committee recommends to the Supervisory Board that the financial statements
referred to above be included in the Core Laboratories' Annual Report on Form
10-K for the year ended December 31, 2001.

Fiscal 2001 Audit Fee Summary

         Set forth below is a summary of the total fees paid to our former
independent public accountants, Arthur Andersen LLP, for fiscal 2001. These fees
consisted of:

  Audit Fees..............................    $   843,000
  Financial Information Systems Design
     and Implementation Fees..............        265,990
  All Other Fees..........................      1,050,680
                                              -----------
       Total..............................    $ 2,159,670
                                              ===========

         In determining the independence of Arthur Andersen LLP for purposes of
its 2001 audit, the Audit Committee considered whether the rendering of
non-audit services was compatible with maintaining Arthur Andersen LLP's
independence and concluded that Arthur Andersen'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, 1997 and ending December 31, 2001. The graph assumes
that the value of the investment in our common shares and each index was $100 at
January 1, 1997 (after giving effect to the 2 for 1 stock split in December
1997) 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, the Supervisory Board, upon the recommendation of
the 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. We have not proposed any formal action be taken at the annual meeting
concerning the engagement of

                                       13


PricewaterhouseCoopers LLP as our independent
public accountants as no such action is legally required under Dutch law or our
articles of association. Representatives of PricewaterhouseCoopers LLP and
Arthur Andersen LLP are not expected to be present at the annual meeting.

         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
filing date of this proxy statement, 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
filing date of this proxy statement, 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, 2001, as
required under Dutch law and our articles of association. In accordance with
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, 2001.

         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
voted unless contrary instructions are indicated thereon.

                                     ITEM 3.
                EXTENSION OF AUTHORITY OF MANAGEMENT BOARD UNTIL
                     NOVEMBER 29, 2003 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 not to 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 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 the 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 30, 2002. We have not repurchased
our common shares in the past but believe that it is in the best interest of our
company and shareholders to have the flexibility to repurchase shares 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.

                                       14


         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 29, 2003.

         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 29, 2003 at a price of not more
than $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 29, 2007

         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 of the
shareholders subsequent to 1995, our shareholders have extended the period such
that the current period is set to expire on May 30, 2006.

         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 29, 2007. 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) on our common and/or preference shares
until May 29, 2007, 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 29, 2007

         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 or 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. 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

                                       15


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 30, 2006.

         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 29, 2007 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 or acquisitions could 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 for a discussion of the NYSE rules regarding stock
issuance.

         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 Common Shares until May 29, 2007, and proxies
executed and returned will be so voted unless contrary instructions are
indicated thereon.

                                     ITEM 6.
                                  OTHER MATTERS

         The Supervisory Board does not know of any other matters that are to be
