AGREEMENT AND PLAN OF MERGER

AGREEMENT AND PLAN OF MERGER, dated as of June 18, 1998 (this
"Merger Agreement"), among Schlumberger Technology Corporation, a Texas
corporation ("STC"), Schlumberger OFS, Inc., a Delaware corporation and a
wholly owned subsidiary of STC ("Sub"), and Camco International Inc., a
Delaware corporation ("Camco").

WHEREAS, the Boards of Directors of STC, Sub and Camco have
each approved the merger of Sub with and into Camco (the "Merger") upon the
terms and subject to the conditions of this Merger Agreement, thus enabling STC
to acquire all of the stock of Camco solely in exchange for voting stock of
Schlumberger Limited, a Netherlands Antilles corporation and the parent of STC
("Schlumberger");

WHEREAS, for federal income tax purposes, it is intended that
the Merger shall qualify as a reorganization within the meaning of Section
368(a)(1)(B) of the Internal Revenue Code of 1986, as amended (the "Code");

WHEREAS, for accounting purposes, it is intended that the
Merger shall be accounted for as a pooling of interests under the requirements
of Opinion No. 16, Business Combinations, of the Accounting Principles Board of
the American Institute of Certified Public Accountants (the "AICPA"), as
amended by Statements of Financial Accounting Standards Board (the "FASB"), and
the related interpretations of the AICPA, FASB, the Emerging Issues Task Force,
and the rules and regulations of the U.S. Securities and Exchange Commission
(the "SEC"); and

WHEREAS, STC, Sub and Camco desire to make certain
representations, warranties, covenants and agreements in connection with the
Merger and also to prescribe various conditions to the Merger;

NOW, THEREFORE, in consideration of the foregoing and the
representations, warranties, covenants and agreements herein contained, the
parties agree as follows:

ARTICLE I
THE MERGER

1.1 The Merger; Effective Time of the Merger. Upon the terms and
conditions of this Merger Agreement and in accordance with the Delaware General
Corporation Law (the "DGCL"), Sub shall be merged with and into Camco at the
Effective Time (as hereinafter defined). The Merger shall become effective
immediately when a certificate of merger (the "Certificate of Merger"),
prepared and executed in accordance with the relevant provisions of the DGCL is
duly filed with the Secretary of State of the State of Delaware or, if agreed
to by the parties, at such time thereafter as is provided in the Certificate of
Merger (the "Effective Time"). The filing of the Certificate of Merger shall
be made as soon as practicable after the closing of the Merger (the "Closing").

-1-
9
1.2 Closing. The Closing shall take place at 10:00 a.m. on a date
to be specified by the parties, which shall be no later than the second
business day after satisfaction (or waiver in accordance with this Merger
Agreement) of the latest to occur of the conditions set forth in Article VI
(the "Closing Date"), at the offices of Xxxxx & Xxxxx, L.L.P., 000 Xxxxxxxxx,
Xxxxxxx, Xxxxx, unless another date or place is agreed to in writing by the
parties.

1.3 Effects of the Merger.

(a) At the Effective Time: (i) Sub shall be merged with
and into Camco, the separate existence of Sub shall
cease and Camco shall continue as the surviving
corporation (Sub and Camco are sometimes referred to
herein as the "Constituent Corporations" and Camco is
sometimes referred to herein as the "Surviving
Corporation") and the merger shall have such effects
as are set forth in Section 259 of the DGCL; (ii) the
Certificate of Incorporation of Camco shall be
amended to change Camco's authorized shares of
capital stock to 1,000 shares, par value $.001 per
share, of common stock, and so amended shall be the
Certificate of Incorporation of the Surviving
Corporation; and (iii) the Bylaws of Camco as in
effect immediately prior to the Effective Time shall
be the Bylaws of the Surviving Corporation.

(b) The directors and officers of Sub at the Effective
Time shall, from and after the Effective Time, be the
directors and officers of the Surviving Corporation
and shall serve until their successors have been duly
elected or appointed and qualified or until their
earlier death, resignation or removal in accordance
with the Surviving Corporation's Certificate of
Incorporation and Bylaws.

ARTICLE II
EFFECT OF THE MERGER ON THE CAPITAL STOCK OF THE
CONSTITUENT CORPORATIONS; EXCHANGE OF CERTIFICATES

2.1 Effect on Capital Stock. At the Effective Time, by virtue of
the Merger and without any action on the part of the holder of any shares of
common stock, par value $0.01 per share, of Camco ("Camco Common Stock") or
capital stock of Sub:

(a) Stock of Sub. Each share of common stock, par value
$1.00 per share, of Sub issued and outstanding
immediately prior to the Effective Time will be
converted into one share of common stock, par value
$.001 per share, of the Surviving Corporation, and
the stock of the Surviving Corporation issued on that
conversion will constitute all of the issued and
outstanding shares of capital stock of the Surviving
Corporation.

(b) Cancellation of Treasury Stock and Related Party
Stock. Each share of Camco Common Stock and all
other shares of capital stock of Camco that are owned
by Camco as treasury stock and any shares of Camco
Common Stock

-2-
10
and all other shares of capital stock of Camco owned
in any case by STC, any entity controlling STC or any
wholly owned Subsidiary (as hereinafter defined) of
such entities or by any wholly owned Subsidiary of
Camco shall be canceled and retired and shall cease
to exist and no Schlumberger Common Stock or cash in
lieu of fractional shares shall be delivered or
deliverable in exchange therefor. As used in this
Merger Agreement, the word "Subsidiary" means, with
respect to any party, any corporation or other
organization, whether incorporated or unincorporated,
of which: (i) such party or any other Subsidiary of
such party is a general partner (excluding
partnerships, the general partnership interests of
which are held by such party or any Subsidiary of
such party that do not have a majority of the voting
interest in such partnership); or (ii) at least a
majority of the securities or other interests having
by their terms ordinary voting power to elect a
majority of the Board of Directors or others
performing similar functions with respect to such
corporation or other organization is, directly or
indirectly, owned or controlled by such party or by
any one or more of its Subsidiaries, or by such party
and any one or more of its Subsidiaries.

(c) Exchange Ratio for Camco Common Stock. Subject to
the provisions of Section 2.2(e) hereof, each share
of Camco Common Stock issued and outstanding
immediately prior to the Effective Time (other than
shares to be canceled in accordance with Section
2.1(b)) shall, at the Effective Time and without the
requirement of any action by the holder thereof, be
exchanged for and converted into 1.18 (the
"Conversion Number") shares of voting common stock,
par value $.01 per share, of Schlumberger
("Schlumberger Common Stock") to be delivered by Sub
pursuant to the Merger. All references in this
Merger Agreement to the Camco Common Stock to be
received pursuant to the Merger shall be deemed to
include the Camco Stock Purchase Rights. All such
shares of Camco Common Stock, when so exchanged and
converted, shall no longer be outstanding and shall
automatically be canceled and retired and shall cease
to exist, and each holder of a certificate
representing any such shares shall cease to have any
rights with respect thereto, except the right to
receive a certificate for the shares of Schlumberger
Common Stock and cash in lieu of fractional shares of
Schlumberger Common Stock as contemplated by Section
2.2(e), upon the surrender of such certificate for
shares of Camco Common Stock in accordance with
Section 2.2, without interest.

(d) Conversion of Stock Options. Each outstanding Camco
Stock Option (as defined in Section 5.5) shall be
converted as provided in Section 5.5.

(e) Adjustment of Conversion Number. If, subsequent to
the date of this Agreement but prior to the Effective
Time, the number of shares of Schlumberger Common
Stock issued and outstanding is changed as a result

-3-
11
of a stock split, reverse stock split, stock
dividend, recapitalization or other similar
transaction, the Conversion Number and other items
dependent thereon shall be appropriately adjusted
herein.

2.2 Exchange of Certificates.

(a) Exchange Agent. As of the Effective Time, Sub shall
deposit with Boston EquiServe LP or such other bank
or trust company designated by STC or another member
of the STC Affiliated Group (as defined below) and
reasonably acceptable to Camco (the "Exchange
Agent"), for the benefit of the holders of shares of
Camco Common Stock, for exchange in accordance with
this Article II, through the Exchange Agent,
certificates representing the shares of Schlumberger
Common Stock (such shares of Schlumberger Common
Stock, together with any dividends or distributions
with respect thereto, and any cash deposits by STC in
order to make payments in lieu of fractional shares
or cash generated by sales of fractional shares of
Schlumberger Common Stock in the open market pursuant
to Section 2.2(e) being hereinafter collectively
referred to as the "Exchange Fund") issuable pursuant
to Section 2.1 in exchange for outstanding shares of
Camco Common Stock. The Exchange Agent shall,
pursuant to irrevocable instructions, deliver the
Schlumberger Common Stock contemplated to be issued
pursuant to Section 2.1 out of the Exchange Fund.
The Exchange Fund shall not be used for any other
purpose. As used in this Merger Agreement, "STC
Affiliated Group" means any entity controlling STC
and any direct or indirect Subsidiary of such entity
or of STC.

(b) Exchange Procedures. As soon as reasonably
practicable after the Effective Time, the Exchange
Agent shall mail to each holder of record of a
certificate or certificates which, immediately prior
to the Effective Time, represented outstanding shares
of Camco Common Stock (the "Certificates") (other
than Camco, STC, any entity controlling STC or any
wholly owned Subsidiaries of any such entities): (i)
a letter of transmittal (which shall specify that
delivery shall be effected and risk of loss and title
to the Certificates shall pass only upon delivery of
the Certificates to the Exchange Agent, and shall be
in such form and have such other provisions as STC or
a designated member of the STC Affiliated Group may
reasonably specify); and (ii) instructions for use in
effecting the surrender of the Certificates in
exchange for certificates representing shares of
Schlumberger Common Stock and any cash in lieu of a
fractional share of Schlumberger Common Stock. Upon
surrender of a Certificate for cancellation to the
Exchange Agent or to such other agent or agents as
may be appointed by STC or a designated member of the
STC Affiliated Group and reasonably acceptable to
Camco, together with such letter of transmittal, duly
executed, and any other required documents, the
holder of such Certificate shall be entitled to
receive in

-4-
12
exchange therefor a certificate representing that
number of whole shares of Schlumberger Common Stock
which such holder has the right to receive pursuant
to the provisions of this Article II and any cash in
lieu of fractional shares of Schlumberger Common
Stock as contemplated by Section 2.2(e), and the
Certificate so surrendered shall forthwith be
canceled. In the event of a transfer of ownership of
Camco Common Stock which is not registered in the
transfer records of Camco, a certificate representing
the appropriate number of shares of Schlumberger
Common Stock may be issued to a transferee if the
Certificate representing such Camco Common Stock is
presented to the Exchange Agent accompanied by all
documents required to evidence and effect such
transfer and by evidence that any applicable stock
transfer taxes have been paid. Until surrendered as
contemplated by this Section 2.2, each Certificate
shall be deemed at any time after the Effective Time
to represent only the right to receive upon such
surrender the certificate representing shares of
Schlumberger Common Stock and cash in lieu of any
fractional shares of Schlumberger Common Stock as
contemplated by this Section 2.2 and all dividends
or other distributions thereon with a record date
after the Effective Time as contemplated by Section
2.2(c). The Exchange Agent shall not be entitled to
vote or exercise any rights of ownership with respect
to the Schlumberger Common Stock held by it from time
to time hereunder, except that it shall receive and
hold all dividends or other distributions paid or
distributed with respect thereto for the account of
persons entitled thereto.

(c) Distributions with Respect to Shares Prior to
Exchange of Certificates. No dividends or other
distributions with respect to Schlumberger Common
Stock declared or made after the Effective Time with
a record date after the Effective Time shall be paid
to the holder of any unsurrendered Certificate with
respect to the Schlumberger Common Stock represented
thereby as a result of the exchange and conversion
provided in Section 2.1(c), and no cash payment in
lieu of fractional shares shall be paid to any such
holder pursuant to Section 2.2(e) until the holder of
such Certificate shall surrender such Certificate.
Subject to the effect of applicable laws, following
surrender of any such Certificate, there shall be
paid to the holder thereof, without interest: (i) at
the time of such surrender, the amount of any cash
payable in lieu of a fractional share of Schlumberger
Common Stock to which such holder is entitled
pursuant to Section 2.2(e) and the amount of
dividends or other distributions with a record date
after the Effective Time theretofore paid with
respect to such whole shares of Schlumberger Common
Stock; and (ii) at the appropriate payment date, the
amount of dividends or other distributions with a
record date after the Effective Time but prior to
surrender and a payment date subsequent to surrender
payable with respect to such whole shares of
Schlumberger Common Stock.

-5-
13
(d) No Further Ownership Rights in Camco Common Stock.
All shares of Schlumberger Common Stock issued in
exchange for and upon the conversion of Camco Common
Stock in accordance with the terms hereof (including
any cash paid pursuant to Section 2.2(c) or 2.2(e))
shall be deemed to have been issued in full
satisfaction of all rights pertaining to such shares
of Camco Common Stock, subject, however, to the
Surviving Corporation's obligation to pay any
dividends or make any other distributions with a
record date prior to the Effective Time that may have
been declared or made by Camco on such shares of
Camco Common Stock in accordance with the terms of
this Merger Agreement or prior to the date hereof and
which remain unpaid at the Effective Time, and after
the Effective Time there shall be no further
registration of transfers on the stock transfer books
of the Surviving Corporation of the shares of Camco
Common Stock that were outstanding immediately prior
to the Effective Time. If, after the Effective Time,
Certificates are presented to the Surviving
Corporation for any reason, they shall be canceled
and exchanged as provided in this Article II.

(e) No Fractional Shares. No certificates or scrip
representing fractional shares of Schlumberger Common
Stock shall be issued pursuant to this Article II,
and, except as provided in this Section 2.2(e), no
dividend or other distribution, stock split or
interest shall relate to any such fractional
security, and such fractional interests shall not
entitle the owner thereof to vote or to any rights of
a security holder of Schlumberger. In lieu of any
fractional security, STC shall pay or cause the
Exchange Agent to pay, to each holder of shares of
Camco Common Stock who would otherwise have been
entitled to a fraction of a share of Schlumberger
Common Stock pursuant to this Article II, an amount
in cash (without interest) equal to such holder's
proportionate interest in the sum of (i) the fraction
of a share of Schlumberger Common Stock to which such
holder would otherwise have been entitled, multiplied
by the closing sale price per share of Schlumberger
Common Stock on the New York Stock Exchange on the
last trading day immediately preceding the date of
the Effective Time, and (ii) the aggregate dividends
or other distributions that are payable with respect
to such shares of Schlumberger Common Stock pursuant
to Section 2.2(c) (such dividends and distributions
being herein called the "Fractional Dividends"). STC
shall timely make available to the Exchange Agent any
cash necessary to make payments in lieu of fractional
shares as aforesaid. For purposes of determining
whether a holder of shares of Camco Common Stock is
to receive payment in lieu of fractional shares, all
shares of Camco Common Stock held of record by such
holder shall be aggregated.

(f) Termination of Exchange Fund. Any portion of the
Exchange Fund that remains undistributed to the
former stockholders of Camco for one year after the
Effective Time shall be delivered to STC upon demand,
and any

-6-
14
stockholders of Camco who have not theretofore
complied with this Article II shall thereafter look
only to STC for payment of their claim for
Schlumberger Common Stock or any cash in lieu of
fractional shares of Schlumberger Common Stock and to
Schlumberger for any dividends or distributions with
respect to Schlumberger Common Stock.

(g) No Liability. Neither Camco nor STC or any other
member of the STC Affiliated Group shall be liable to
any holder of shares of Camco Common Stock or
Schlumberger Common Stock, as the case may be, for
such shares (or dividends or distributions with
respect thereto) or cash in lieu of fractional shares
of Schlumberger Common Stock delivered to a public
official pursuant to any applicable abandoned
property, escheat or similar law.

ARTICLE III
REPRESENTATIONS AND WARRANTIES

3.1 Representations and Warranties of Camco. Subject to the
exceptions set forth in the disclosure letter to be delivered to STC and Sub in
connection herewith (the "Camco Disclosure Letter"), Camco represents and
warrants to STC and Sub as follows:

(a) Organization, Standing and Power. Each of Camco and
its Subsidiaries is a corporation, limited liability
company or partnership duly organized, validly
existing and in good standing under the laws of its
state of incorporation or organization, has all
requisite corporate power and authority to own, lease
and operate its properties and to carry on its
business as now being conducted, and is duly
qualified and in good standing to do business in each
jurisdiction in which the business it is conducting,
or the operation, ownership or leasing of its
properties, makes such qualification necessary, other
than where the failure to be so organized or so to
qualify (individually or in the aggregate) would not
have a Material Adverse Effect (as defined below) on
Camco. Camco has heretofore delivered to STC
complete and correct copies of its Certificate of
Incorporation and Bylaws. Except as set forth in the
exhibits to the Camco SEC Documents (as defined in
Section 3.1(d)), Camco does not own, directly or
indirectly, any capital stock or other ownership
interest in any Subsidiary which would be required to
be listed as a Subsidiary of Camco under the rules of
the SEC with the filing by Camco of an Annual Report
on Form 10-K. As used in this Merger Agreement a
"Material Adverse Effect" shall mean any effect or
change that is or would be materially adverse to the
business, operations, assets, condition (financial or
otherwise) or results of operations of (i) in respect
of Camco, Camco and its direct and indirect
Subsidiaries, taken as a whole, and (ii) in respect
of the STC Affiliated Group, all the members of the
STC Affiliated Group taken as a whole; provided,
however, a Material Adverse Effect shall not include
(A) any effect or change, including changes in
national or international economic

-7-
15
conditions, relating to or affecting the oil and gas
service and equipment industry as a whole (including
a decline in worldwide oil and gas commodity prices),
(B) changes, or possible changes, in foreign,
Federal, state or local statutes and regulations, (C)
the loss of employees, customers or suppliers by
Camco or one or more of its Subsidiaries as a
consequence of any announcement relating to the
Merger or (D) any action taken or required to be
taken to satisfy any requirement imposed in
connection with the review of the Merger under the
HSR Act.

(b) Capital Structure. As of the date hereof, the
authorized capital stock of Camco consists of
100,000,000 shares of Camco Common Stock and
10,000,000 shares of preferred stock, par value $.01
per share ("Camco Preferred Stock"). One common

pursuant to the Rights Agreement, dated as of
December 15, 1994, between Camco and First Chicago
Trust Company of New York, as rights agent, as
amended by the First Amendment to Rights Agreement,
dated as of October 21, 1997 (as so amended, the
"Rights Agreement"), is associated with each
outstanding share of Camco Common Stock. At the
close of business on June 8, 1998: (i) 37,968,796
shares of Camco Common Stock and no shares of Camco
Preferred Stock were issued and outstanding, and an
aggregate of 2,054,358 shares of Camco Common Stock
and no shares of Camco Preferred Stock were reserved

to be issued, delivered, sold, purchased, redeemed or
acquired, additional shares of capital stock or any
Voting Debt or other voting securities of Camco or of
any Subsidiary of Camco, or obligating Camco or any
Subsidiary of Camco to grant, extend or enter into
any such option, warrant, call, right, commitment or
agreement. There are not as of the date hereof and
there will not be at the Effective Time any
stockholder agreements, voting trusts or other
agreements or understandings to which Camco is a
party or by which it is bound relating to the voting
of any shares of the capital stock of Camco. There
are no restrictions on Camco to vote the stock of any
of its Subsidiaries.

(i) The Board of Directors of Camco has approved
the Merger and this Merger Agreement, by vote of the directors
with no negative vote, and declared the Merger and this Merger
Agreement to be in the best interests of the stockholders of
Camco. The directors of Camco have advised Camco and STC that
they intend to vote or cause to be voted all of the shares of
Camco Common Stock for which they have voting power in favor
of approval of the Merger and this Merger Agreement. Camco
has all requisite corporate power and authority to enter into
this Merger Agreement and, subject, with respect to
consummation of the Merger, to approval of this Merger
Agreement and the Merger by the stockholders of Camco in
accordance

have been duly authorized by all necessary corporate action on
the part of Camco, subject, with respect to consummation of
the Merger, to approval of this Merger Agreement and the
Merger by the stockholders of Camco in accordance with the
DGCL. This Merger Agreement has been duly executed and
delivered by Camco and, subject, with respect to consummation
of the Merger, to approval of this Merger Agreement and the
Merger by the stockholders of Camco in accordance with the
DGCL, and assuming this Merger Agreement constitutes the valid
and binding obligation of STC and Sub, constitutes a valid and
binding obligation of Camco enforceable in accordance with its
terms, subject, as to enforceability, to bankruptcy,
insolvency, reorganization and other laws of general
applicability relating to or effecting creditors' rights and
to general principles of equity and limitations imposed on
indemnity obligations by applicable federal and state
securities laws.

(l) Employee Matters; ERISA.

(i) Benefit Plans. Schedule 3.1(l)(i) to the
Camco Disclosure Letter contains a true and complete list of
each of the following items: each employee benefit plan,
program or arrangement covering any current or former officer,
director, employee or independent contractor of Camco (or any
of its Subsidiaries) or any of their dependents or
beneficiaries (each, a "Camco Beneficiary") including, but not
limited to, any "employee benefit plan" within the meaning of
Section 3(3) of the Employee Retirement Income Security Act of
1974, as amended ("ERISA"), whether or not terminated or
covered by ERISA, if Camco or any of its Subsidiaries could
have statutory or contractual liability with respect thereto
on or after the date hereof but excluding immaterial plans
maintained by Subsidiaries of Camco covering employees located
outside the United States where such plans cover fewer than
100 people. The items described above, together with each
management, employment, deferred compensation, severance,

services with or covering any Camco Beneficiary, whether or
not terminated, if Camco or any of its Subsidiaries could have
statutory or contractual liability with respect thereto on or

the "Camco Benefit Plans."

(ii) Contributions and Payments. All material
contributions and other material payments required to have
been made by Camco or any entity required to be aggregated
therewith pursuant to Code Section 414 (a "Camco ERISA
Affiliate") with respect to any Camco Benefit Plan (or to any
person pursuant to the terms thereof) have been or will be
timely made and all such amounts properly accrued

-16-
24
through the date of this Merger Agreement have been reflected
in the financial statements of Camco included in the Camco SEC
Documents.

(iii) Qualification; Compliance. Each Camco Benefit
Plan that is intended to be "qualified" within the meaning of
Code Section 401(a) has been determined by the IRS to be so
qualified or the applicable remedial period applicable to the
Plan will not have ended prior to the Effective Time, and, to
the best knowledge of Camco, no event or condition exists or
has occurred that would reasonably be expected to result in
the revocation or denial of any such determination which would
have a Material Adverse Effect on Camco. With respect to each
Camco Benefit Plan, Camco and each Camco ERISA Affiliate are
in compliance with, and each Camco Benefit Plan and related
source of benefit payment is and has been operated in
compliance with, all applicable laws, rules and regulations
governing such plan or source, including, without limitation,
ERISA, the Code and applicable local law (including non-U.S.
law), except for violations that would not have a Material
Adverse Effect on Camco. To the best knowledge of Camco,
except as set forth in Schedule 3.1(l)(iii), no Camco Benefit
Plan is subject to any ongoing audit, investigation, or other
administrative proceeding of the IRS, the Department of Labor,
or any other federal, state, or local governmental entity or
is scheduled to be subject to such an audit investigation or
proceeding.

(iv) Liabilities. With respect to the Camco
Benefit Plans, individually and in the aggregate, and, to the
best knowledge of Camco, there exists no condition or set of
circumstances that could subject Camco or any Camco ERISA
Affiliate to any liability arising under the Code, ERISA or
any other applicable law (including, without limitation, any
liability to or under any such plan or to the Pension Benefit
Guaranty Corporation ("PBGC"), or under any indemnity
agreement to which Camco or any Camco ERISA Affiliate is a
party), which liability, excluding liability for benefit
claims, funding obligations and PBGC insurance premiums, each
payable in the ordinary course, would have a Material Adverse
Effect on Camco. No claim, action or litigation has been
made, commenced or, to the best knowledge of Camco,
threatened, by or against Camco or any of its Subsidiaries
with respect to any Camco Benefit Plan (other than for
benefits or PBGC premiums payable in the ordinary course) that
would have a Material Adverse Effect on Camco.

(v) Retiree Welfare Plans. Except as disclosed
in Schedule 3.1(l)(v) to the Camco Disclosure Letter, no Camco
Benefit Plan that is a "welfare plan" (within the meaning of
ERISA Section 3(1)) provides benefits for any retired or
former employees (other than as required pursuant to ERISA
Section 601).

(vi) Payments Resulting from Merger. Except as
disclosed on Schedules 3.1(k)(v), 3.1(l)(vi), 4.1(h) and 5.14
to the Camco Disclosure Letter, the consummation or
announcement of any transaction contemplated by this Merger
Agreement will not (either alone or upon the occurrence of any
additional or further

-17-
25
acts or events) result in (A) any payment (whether of
severance pay or otherwise) becoming due from the Company or
Camco or any of their Subsidiaries to any Camco Beneficiary or
to the trustee under any "rabbi trust" or similar arrangement,
or (B) any benefit under any Camco Benefit Plan being
established or increased, or becoming accelerated, vested or
payable.

(vii) Funded Status of Plans. Each Camco Benefit
Plan that is subject to either the minimum funding
requirements of ERISA Section 302 or to Title IV of ERISA has
assets that, as of the date hereof, have a fair market value
not less than the present value of the accrued benefit
obligations thereunder on a termination basis, as of the date
hereof, based on the actuarial methods, tables and assumptions
utilized by such plan's independent actuary in preparing such
plan's most recently prepared actuarial valuation report,
except to the extent that applicable law would require the use
of different actuarial assumptions if such plan was to be
terminated as of the date hereof, in which case those
different assumptions shall apply for purposes of this
representation. Camco and its Subsidiaries have no unfunded
liabilities, as determined under local funding requirements,
with respect to any Camco Benefit Plans that cover such
non-U.S. employees which would, in the aggregate, have a
Material Adverse Effect on Camco.

(viii) Multiemployer Plans. Except as described on
Schedule 3.1(l)(viii) to the Camco Disclosure Letter, no Camco
Benefit Plan is or was a "multiemployer plan" (within the
meaning of ERISA Section 4001(a)(3)), a multiple employer plan
described in Code Section 413(c), or a "multiple employer
welfare arrangement" (within the meaning of ERISA Section
3(40)). Except as disclosed in Schedule 3.1(l)(viii) to the
Camco Disclosure Letter, neither Camco nor any Camco ERISA
Affiliate has been obligated to contribute to, or otherwise
has or has had any liability with respect to, any
multiemployer plan, multiple employer plan, or multiple
employer welfare arrangement.

(m) Labor Matters. Except as set forth in Schedule
3.1(m) to the Camco Disclosure Letter,

(i) neither Camco nor any of its Subsidiaries is
a party to any collective bargaining agreement or other
current labor agreement with any labor union or organization,
and to the knowledge of Camco and its Subsidiaries there is no
current union representation dispute involving employees of
Camco or any of its Subsidiaries nor does Camco or any of its
Subsidiaries know of any activity or proceeding of any labor
organization (or representative thereof) or employee group (or
representative thereof) to organize any such employees;

(ii) there is no unfair labor practice charge or
grievance arising out of a collective bargaining agreement or
other grievance procedure against Camco or any of its
Subsidiaries pending, or, to the knowledge of Camco or any of
its Subsidiaries, threatened, that has, or would have, a
Material Adverse Effect on Camco;

-18-
26
(iii) there is no complaint, lawsuit or proceeding
in any forum by or on behalf of any present or former
employee, any applicant for employment or any classes of the
foregoing alleging breach of any express or implied contract
of employment, any law or regulation governing employment or
the termination thereof or other discriminatory, wrongful or
tortious conduct in connection with the employment
relationship against Camco or any of its Subsidiaries pending,
or, to the knowledge of Camco or any of its Subsidiaries,
threatened, that has, or would have, a Material Adverse Effect
on Camco;

(iv) there is no strike, dispute, slowdown, work
stoppage or lockout pending, or, to the knowledge of Camco or
any of its Subsidiaries, threatened, ]against or involving
Camco or any of its Subsidiaries that has, or could have, a
Material Adverse Effect on Camco;

(v) Camco and each of its Subsidiaries are in
compliance with all applicable laws respecting employment and
employment practices, terms and conditions of employment,
wages, hours of work and occupational safety and health,
except for non-compliance that does not have, and would not
have, a Material Adverse Effect on Camco; and

(vi) there is no proceeding, claim, suit, action
or governmental investigation pending or, to the knowledge of
Camco or any of its Subsidiaries, threatened, in respect to
which any current or former director, officer, employee or
agent of Camco or any of its Subsidiaries is or may be
entitled to claim indemnification from Camco or any of its
Subsidiaries (A) pursuant to their respective charters or
bylaws, (B) as provided in any indemnification agreement to
which Camco or any Subsidiary of Camco is a party or (C)
pursuant to applicable law that has, or would have, a Material
Adverse Effect on Camco.

(n) Intangible Property. Camco and its Subsidiaries
possess or have adequate rights to use all
trademarks, trade names, patents, service marks,
brand marks, brand names, computer programs,
database, industrial designs, know how, trade
secrets, copyrights and other intellectual property
rights which are material to the condition or conduct
of the business operations of Camco and its
Subsidiaries (collectively, the "Camco Intangible
Property"). Except as set forth on Schedule 3.1(n)
to the Camco Disclosure Letter, all of the Camco
Intangible Property is owned by Camco or its
Subsidiaries free and clear of any and all liens,
claims or encumbrances, except those the failure to
so own would not have a Material Adverse Effect on
Camco. To the knowledge of Camco, the operation of
the businesses of each of Camco or its Subsidiaries
does not, in any material respect, conflict with,
infringe upon, violate or

-19-
27
interfere with or constitute an appropriation of any
right, title, interest or goodwill, including,
without limitation, any intellectual property right,
trade secret, trademark, trade name, patent, service
xxxx, brand xxxx, brand name, computer program,
database, industrial design, copyright or any pending
application therefor of any other person and there
have been no claims made in connection therewith and
neither Camco nor any of its Subsidiaries has
received any notice of any claim or otherwise knows
that any of the Camco Intangible Property is invalid
or conflicts with the rights of any other person or
has not been used or enforced or has been failed to
be used or enforced in a manner that would result in
the abandonment, cancellation or unenforceability of
any of the Camco Intangible Property and would
individually or in the aggregate result in a Material
Adverse Effect on Camco. All failures of the
representations and warranties set forth in this
Section 3.1(n) to be true, in the aggregate, would
not result in a Material Adverse Effect on Camco.

currently conducted. All such assets and properties, other
than assets and properties in which Camco or any of the
Subsidiaries has leasehold interests, are free and clear of
all liens, other than those set forth in the Camco SEC
Documents, and except for liens, that, in the aggregate, do
not and will not materially interfere with the ability of
Camco or any of its Subsidiaries to conduct business as
currently conducted.

(ii) Except as would not have a Material Adverse
Effect on Camco, each of Camco and its Subsidiaries has
complied in all material respects with the terms of all leases

and its Subsidiaries enjoys peaceful and undisturbed
possession under all such leases.

(x) Amendment to the Camco Rights Agreement. Camco has
amended the Rights Agreement so that none of the
execution and delivery of this Merger Agreement, the
conversion of shares of Camco Common Stock into the

transaction contemplated hereby will cause (A) the
Camco Rights to become exercisable under the Rights

operate its properties and to carry on its business
as now being conducted, and is duly qualified and in
good standing to do business in each jurisdiction in
which the business it is conducting, or the

aggregate) would not have a Material Adverse Effect
on the STC Affiliated Group.

32
(b) Capital Structure. As of the date hereof, the

accordance with its terms; provided, however, that such
enforceability is subject to bankruptcy, insolvency,
reorganization and other laws of general applicability
relating to or affecting creditors' rights and to general
principles of equity and limitations imposed on indemnity
obligations by applicable federal and state securities laws.

(ii) Except as set forth on Schedule 3.2(c)(ii) to
the STC Disclosure Letter, the execution and delivery of this
Merger Agreement does not, and the consummation of the
transactions contemplated hereby and compliance with the
provisions hereof will not, conflict with, or result in any
violation of, or default (with or without notice or lapse of
time, or both) under, or give rise to a right of termination,
cancellation or acceleration of any obligation or to the loss
of a material benefit under, or result in the creation of any
lien, security interest, charge or encumbrance upon any of the
properties or assets of STC or Sub under, any provision of (A)

any loan or credit agreement, note, bond, mortgage, indenture,

conflicts, violations, defaults, rights, liens, security
interests, charges or encumbrances that, individually or in
the aggregate, would not have a Material Adverse Effect on the
STC Affiliated Group, materially impair the ability of STC or
Sub to perform its respective obligations hereunder or prevent
in any material respect the consummation of any of the
transactions contemplated hereby.

(iii) No consent, approval, order or authorization
of, or registration, declaration or filing with, or permit
from any Governmental Entity is required by or with respect to
STC or any other member of the STC Affiliated Group in
connection with the execution and delivery of this Merger
Agreement by STC and Sub or the consummation by STC and Sub of
the transactions contemplated hereby, as to which the failure
to obtain or make would have a Material Adverse Effect on the
STC Affiliated Group, except for: (A) the filing of a
premerger notification report under the HSR Act and the
expiration or termination of the applicable waiting period
with respect thereto; (B) the filing with the SEC of the Proxy
Statement, the S-4, such reports under Section 13(a) of the

action or proceeding pending, or, to the best
knowledge of STC, threatened against or affecting any
member of the STC Affiliated Group ("STC

rule or order of any Governmental Entity or

contemplated by this Merger Agreement.

financial and accounting officers, prior to the date
hereof, no member of the STC Affiliated Group has

notwithstanding any other provision of this Merger
Agreement, Camco may, prior to the vote of the

not thereafter if the Merger is approved thereby, in

confidentiality agreement) as the Confidentiality
Agreements between Camco and STC described in Section
5.1 hereof, provided that the Board of Directors of

on the advice of outside counsel), it determines to
be a Superior Proposal, the Board of Directors may
withdraw or modify its approval or recommendation of
this Merger Agreement or the Merger and may (subject
to the following sentence) terminate this Merger
Agreement, in each case at any time after midnight on
the second business day following STC's receipt of
written notice (a "Notice of Superior Proposal")
advising STC that the Board of Directors has received
an Acquisition Proposal which it has determined to be
a Superior Proposal, specifying the material terms
and conditions of such Superior Proposal (including
the proposed financing for such proposal and a copy
of any documents conveying such proposal) and
identifying the party making such Superior Proposal.
Camco may terminate this Merger Agreement pursuant to
the preceding sentence only if the stockholders of
Camco shall not yet have voted upon the Merger and
Camco shall have paid to STC the Termination Fee (as
defined in Section 7.2(b)). Any of the foregoing to
the contrary notwithstanding, Camco may engage in
discussions with any party that has made an
unsolicited takeover proposal for the limited purpose
of determining whether such proposal (as opposed to
any further negotiated proposal) is a Superior
Proposal. Nothing contained herein shall prohibit
Camco from taking and disclosing to its stockholders
a position contemplated by Rule 14e-2(a) following
STC's receipt of a Notice of Superior Proposal.

(c) For purposes of this Merger Agreement, a "Superior
Proposal" means any bona fide proposal to acquire,
directly or indirectly, all of the Camco Common Stock
then outstanding or all or substantially all of the
assets of Camco and its Subsidiaries, and otherwise
on terms which a majority of the disinterested
members of the Board of Directors of Camco determines
in its good faith reasonable judgment (based on the
written advice of a financial advisor of national
recognized reputation, a copy of which shall be
provided to STC) to be more favorable to Camco's
stockholders than the Merger. In reaching such good
faith determination, the Board of Directors of Camco
will give significant consideration to whether an
Acquisition Proposal includes definite financing.

4.3 Pooling of Interests. If so requested by STC, Camco shall,
and shall cause its independent accountants and other representatives to, fully
cooperate with STC, its independent accountants and other representatives in
seeking to obtain confirmation from the SEC that the Merger may be accounted
for as a "pooling of interests."

Affiliated Group (a) a copy of each report, schedule, registration statement
and other document filed or received by it during such period purs uant to SEC
requirements and (b) all other information concerning its business, properties

the consummation of the transactions contemplated by this Merger Agreement and
the Transaction Agreement. Notwithstanding the foregoing, neither Camco nor
STC shall be required to give the other party any information that is subject
to a confidentiality agreement and that relates primarily to a party other than
Camco and its subsidiaries on the one hand or a member of the STC Affiliated
Group on the other. The Confidentiality Agreements dated as of May 11, 1998
between STC and Camco (the "Confidentiality Agreements") shall apply with
respect to information furnished thereunder or hereunder and any other
activities contemplated thereby.

5.2 Camco Stockholders' Meeting. Camco shall call a meeting of
its stockholders to be held as promptly as practicable after the date hereof
for the purpose of voting upon this Merger Agreement and the Merger. Subject
to Sections 4.2(a) and (b), Camco will, through its Board of Directors,
recommend to its stockholders approval of such matters and not rescind such
recommendation and shall use its best efforts to obtain approval and adoption
of this Merger Agreement and the Merger by its stockholders. Camco shall use
all reasonable efforts to hold such meeting as soon as practicable after the
date upon which the S-4 becomes effective.

5.3 Legal Conditions to Merger.

(i) Except as otherwise provided herein, each of Camco,
STC and Sub will take all reasonable actions
necessary to comply promptly with all legal
requirements that may be imposed on such party with
respect to the Merger (including, without limitation,
furnishing all information required under the HSR Act
and in connection with approvals of or filings with
any other Governmental Entity) and will promptly
cooperate with and furnish

-33-
41
information to each other in connection with any such
requirements imposed upon any of them or any of their
Subsidiaries in connection with the Merger. Each of
Camco and STC will, and will cause its respective
Subsidiaries to, take all actions necessary to obtain
(and will cooperate with each other in obtaining) any
consent, acquiescence, authorization, order or
approval of, or any exemption or nonopposition by,
any Governmental Entity or court required to be
obtained or made by Camco, STC or any of their
Subsidiaries in connection with the Merger or the
taking of any action contemplated thereby or by this
Merger Agreement, including complying with any
requests or orders made by the Justice Department or
the Federal Trade Commission in connection with the
Merger.

(ii) Each of the parties hereto shall file a premerger
notification and report form under the HSR Act with
respect to the Merger as promptly as reasonably
possible following execution and delivery of this
Agreement. Each of the parties agrees to use
reasonable efforts to promptly respond to any request
for additional information pursuant to Section (e)(1)
of the HSR Act. Except as otherwise required by
United States regulatory considerations, Camco will
furnish to STC copies of all correspondence, filings
or communications (or memoranda setting forth the
substance thereof (collectively, "Company HSR
Documents")) between Camco, or any of its respective
representatives, on the one hand, and any
governmental entity, or members of the staff of such
agency or authority, on the other hand, with respect
to this Agreement or the Merger; provided; however,
that (x) with respect to documents and other
materials filed by or on behalf of Camco with the
Antitrust Division of the Department of Justice, the
Federal Trade Commission, or any state attorneys
general that are available for review by STC, copies
will not be required to be provided to STC and (y)
with respect to any Camco HSR Documents (1) that
contain any information which, in the reasonable
judgment of Fulbright & Xxxxxxxx L.L.P., should not
be furnished to STC because of antitrust
considerations or (2) relating to a request for
additional information pursuant to Section (e)(1) of
the HSR Act, the obligation of Camco to furnish any
such Camco HSR Documents to STC shall be satisfied by
the delivery of such Camco HSR Documents on a
confidential basis to Xxxxx & Xxxxx, L.L.P., pursuant
to a confidentiality agreement in form and substance
reasonably satisfactory to STC. Except as otherwise
required by United States regulatory considerations,
STC will furnish to Camco copies of all
correspondence, filings or communications (or
memoranda setting forth the substance thereof
(collectively, "STC HSR Documents")) between STC or
any of its representatives, on the one hand, and any
Governmental Entity, or member of the staff of such
agency or authority, on the other hand, and any
Governmental Entity, or member of the staff of such
agency or authority, on the other hand, with respect
to this Agreement or the Merger; provided, however,
that (x) with respect to documents and other
materials filed by or

-34-
42
on behalf of STC with the Antitrust Division of the
Department of Justice, the Federal Trade Commission,
or any state attorneys general that are available for
review by Camco, copies will not be required to be
provided to Camco, and (y) with respect to any STC
HSR Documents (1) that contain information which, in
the reasonable judgment of Xxxxx & Xxxxx, L.L.P.,
should not be furnished to Camco because of antitrust
considerations or (2) relating to a request for
additional information pursuant to Section (e)(1) of
the HSR Act, the obligation of STC to furnish any
such STC HSR Documents to Camco shall be satisfied by
the delivery of such STC HSR Documents on a
confidential basis to Fulbright & Xxxxxxxx L.L.P.
pursuant to a confidentiality agreement in form and
substance reasonably satisfactory to Camco.

(iii) In the event that any governmental body with
jurisdiction of this Merger shall require any member
of the STC Affiliated Group to agree to take or not
to take any action as a condition to approving or not
objecting to the Merger, STC will take such action
(A) if the loss in annual revenues to the Surviving
Corporation would reasonably be expected not to
exceed $75 million during the ensuing twelve months
following the Closing, or (B) if STC otherwise
considers it reasonable and appropriate in the
circumstances to take such action.

5.4 Agreements of Others. No later than five days prior to the
day on which the meeting of stockholders of Camco to approve the Merger is
held, Camco shall use its best efforts to cause each person who STC reasonably
believes to be an affiliate of Camco within the meaning of Rule 145 of the
General Rules and Regulations of the SEC under the Securities Act, after
consultation with Camco and its legal counsel, to deliver (a) a written
agreement, in the form to be approved by STC and Camco, that such persons will
not sell, pledge, transfer or otherwise dispose of any shares of Schlumberger
Common Stock issued to such persons pursuant to the Merger or any other shares
of Schlumberger Common Stock that such persons control the disposition of,
except pursuant to an effective registration statement or in compliance with
Rule 145 or an exemption from the registration requirements of the Securities
Act and (b) a written agreement, in the form to be approved by STC and Camco,
that such persons will not sell or in any other way reduce his or her risk
relative to any shares of Schlumberger Common Stock received in the Merger
(within the meaning of Section 201.01 of the SEC's Financial Reporting Release
No. 1), until such time as financial results (including combined sales and net
income) covering at least 30 days of post-merger operations have been
published, except as permitted by Staff Accounting Bulletin No. 76 (or any
successor thereto) issued by the SEC.

5.5 Stock Options. At the Effective Time, each outstanding option
to purchase Camco Common Stock and any stock appreciation rights related
thereto that has been granted pursuant to the Camco Stock Plans ("Camco Stock
Option"), whether vested or unvested, shall be deemed to constitute an option
to acquire, on the same terms and conditions as were applicable under such
Camco Stock Option, a number of shares of Schlumberger Common Stock equal to
the number of

-35-
43
shares of Camco Common Stock purchasable pursuant to such Camco Stock Option
multiplied by the Conversion Number, at a price per share equal to the
per-share exercise price for the shares of Camco Common Stock purchasable
pursuant to such Camco Stock Option divided by the Conversion Number; provided,
however, that in the case of any Camco Stock Option to which Code Section 421
applies by reason of its qualification under any of the Code Sections 422-424,
the exercise price and number of shares subject to such option shall be
determined in a manner that meets the requirements for issuing or assuming a
stock option in a transaction to which Code Section 424(a) applies and provided
further, that the number of shares of Schlumberger Common Stock that may be
purchased upon exercise of such Camco Stock Option shall not include any
fractional share and, upon exercise of such Camco Stock Option, a cash payment
shall be made for any fractional share based upon the closing price of a share
of Schlumberger Common Stock on the NYSE on the last trading day of the
calendar month immediately preceding the date of exercise.

5.6 Indemnification; Directors' and Officers' Insurance.

(a) Camco shall, and from and after the Effective Time,
STC and the Surviving Corporation shall, indemnify,
defend and hold harmless each person who is now, or
has been at any time prior to the date hereof or who
becomes prior to the Effective Time, an officer or
director of Camco or any of its Subsidiaries or an
employee of Camco or any of its Subsidiaries who acts
as a fiduciary under any Camco Benefit Plans (the
"Indemnified Parties") against all losses, claims,
damages, costs, expenses (including attorneys' fees),
liabilities or judgments or amounts that are paid in
settlement with the approval of the indemnifying
party (which approval shall not be unreasonably
withheld) of or in connection with any threatened or
actual claim, action, suit, proceeding or
investigation based in whole or in part on or arising
in whole or in part out of the fact that such person
is or was a director, officer or such employee of
Camco or any Subsidiary, whether pertaining to any
matter existing or occurring at or prior to the
Effective Time and whether asserted or claimed prior
to, or at or after, the Effective Time (including
arising out of or relating to the Merger, the
consummation of the transactions contemplated herein,
and any action taken in connection therewith)
("Indemnified Liabilities"). Any Indemnified Party
wishing to claim indemnification under this Section
5.6, upon learning of any such claim, action, suit,
proceeding or investigation, shall notify Camco (or
after the Effective Time, STC and the Surviving
Corporation), but the failure so to notify shall not
relieve a party from any liability that it may have
under this Section 5.6, except to the extent such
failure materially prejudices such party. The
Indemnified Parties as a group may retain only one
law firm to represent them with respect to each such
matter unless there is, under applicable standards of
professional conduct, a conflict on any significant
issue between the positions of any two or more
Indemnified Parties.

-36-
44
(b) STC shall use its reasonable best efforts to purchase
and maintain in effect for the benefit of the
Indemnified Parties for a period of six years after
the Effective Time, directors' and officers'
liability insurance of at least the same coverage and
amounts containing terms and conditions that are no
less advantageous in any material respect to the
Indemnified Parties than that maintained by Camco and
its Subsidiaries as of the date of this Merger
Agreement with respect to matters arising before the
Effective Time, provided that STC shall not be
required to pay an annual premium for such insurance
in excess of two times the last annual premium paid
by Camco prior to the date hereof, but in such case
shall purchase as much coverage as possible for such
amount.

(c) All rights to indemnification for acts or omissions
occurring prior to the Effective Time now existing in
favor of the Indemnified Parties as provided in the
Certificate of Incorporation or by-laws of Camco or
its subsidiaries and in any indemnification
agreements to which they are parties shall survive
the Merger, and the Surviving Corporation shall
continue such indemnification rights for acts or
omissions prior to the Effective Time in full force
and effect in accordance with their terms and STC
shall be financially responsible therefor. The
provisions of this Section 5.6 are intended to be for
the benefit of, and shall be enforceable by, the
parties hereto and each Indemnified Party, and his or
her heirs and representatives.

5.7 Agreement to Defend. In the event any claim, action, suit,
investigation or other proceeding by any governmental body or other person or
other legal or administrative proceeding is commenced that questions the
validity or legality of the transactions contemplated hereby or seeks damages
in connection therewith, the parties hereto agree to cooperate and use their
reasonable efforts to defend against and respond thereto.

5.8 Accounting Matters. During the period from the date of this
Merger Agreement through the Effective Time, unless the parties shall otherwise
agree in writing, neither STC nor Camco or any of their respective Subsidiaries
shall take or fail to take any reasonable action which action or failure to act
would knowingly jeopardize the treatment of Camco's combination with Sub as a
pooling of interests for accounting purposes and each of STC and Camco will
take all reasonable steps to permit the Merger to be treated as a pooling of
interest for accounting purposes.

5.9 Public Announcements. STC and Camco will agree with each
other with respect to the contents thereof before issuing any press release or
otherwise making any public statements with respect to the transactions
contemplated by this Merger Agreement, except as may be required by applicable
law or by obligations pursuant to any listing agreement with any national
securities exchange or transaction reporting system.

5.10 Other Actions. Except as contemplated by this Merger
Agreement, neither STC nor Camco shall, and shall not permit any of its
Subsidiaries to, take or agree or commit to take any

-37-
45
action that is reasonably likely to result in any of its respective
representations or warranties hereunder being untrue in any material respect or
in any of the conditions to the Merger set forth in Article VI not being
satisfied.

5.11 Advice of Changes; SEC Filings. STC and Camco shall confer on
a regular basis with each other, report on operational matters and promptly
advise each other orally and in writing of any change or event having, or
which, insofar as can reasonably be foreseen, could have, a Material Adverse
Effect on the STC Affiliated Group or Camco, as the case may be. Camco and STC
shall promptly provide each other (or their respective counsel) copies of all
filings made by such party (or in the case of STC, made by Schlumberger) with
the SEC or any other state or federal Governmental Entity in connection with
this Merger Agreement and the transactions contemplated hereby.

5.12 Reorganization It is the intention of STC and Camco that the
Merger will qualify as a reorganization described in Section 368(a)(1)(B) of
the Code (and any comparable provisions of applicable state law). Neither
Camco nor STC (or any of their respective Subsidiaries) will take or omit to
take any action (whether before, on or after the Closing Date) that would cause
the Merger not to be so treated. The parties will characterize the Merger as
such a reorganization for purposes of all Returns and other filings.

5.13 Delivery of Schlumberger Common Stock. Prior to the Merger,
STC will acquire and will contribute to Sub that number of shares of
Schlumberger Common Stock which Sub is required to deliver pursuant to Section
2.1(c).

5.14 Employee Matters.

(a) Employment. STC and Camco agree that all employees
of Camco and its Subsidiaries immediately prior to
the Effective Time shall be employed by the Surviving
Corporation immediately after the Effective Time
(referred to herein during such continuing employment
as "Continuing Employees").

(b) Benefits Accrued at the Effective Time. STC will
take, or cause the appropriate member of the STC
Group (as defined below) to take, all actions
necessary to preserve and maintain with respect to
the Camco Benefit Plans in effect at the Effective
Time, benefits accrued and service credit accrued to
the Continuing Employees and the Camco Retirees
during employment with Camco and its Subsidiaries
prior to the Effective Time; provided, however, that
unless otherwise expressly provided in this
Agreement, nothing contained in this Section 5.14
shall preclude any member of the STC Group from
amending any such plan to cease the accrual of
benefits thereunder after the Effective Time or
terminating any such plan provided such amendment or
termination does not adversely affect the benefits
accrued thereunder, if any, at the Effective Time.
As used herein, the "STC Group" means the Surviving
Corporation and all members of the STC Affiliated
Group.

-38-
46
(c) General Agreement as to Employee Benefit Coverage
after the Effective Time. Unless otherwise expressly
addressed in this Section 5.14, this Section 5.14(c)
shall govern the obligations of the STC Group with
respect to employee benefits for Continuing Employees
and for employees who are eligible for retirement
benefits attributable to employment with Camco or a
Camco Affiliate, whether before, at or after the
Effective Time (referred to herein as "Camco
Retirees").

(i) Benefit Coverage. STC will take, and cause
the appropriate member of the STC Group to
take, such actions as are necessary so that
for the remainder of the calendar year in
which the Effective Time occurs, Continuing
Employees and Camco Retirees will be provided
with employee benefit plans, programs,
policies and arrangements that are no less
favorable to such employees and retirees as
those provided as of the Effective Time.
Thereafter, the STC Group will provide the
Continuing Employees and Camco Retirees with
benefits that, in the aggregate, are not less
favorable than those then provided to
Similarly Situated Employees (as defined in
the next sentence). As used herein, the
phrase "Similarly Situated Employees" means
that group of employees (or retirees, as
applicable) of the STC Group principally
employed in the oil field service operations
of the STC Group generally whose job
descriptions, working conditions, wage rates
and other conditions of employment are (or
were) the most similar to those of the
Continuing Employees (or the Camco Retirees)
or, if there is no such group of employees, a
group of employees engaged in the drilling or
completing of oil and/or gas xxxxx, all as
reasonably determined by STC.

(ii) Service Crediting. In the event a STC Group
employee benefit plan, program, policy or
arrangement is made available to Continuing
Employees or Camco Retirees, all periods of
service with Camco and its Subsidiaries and
any other entity that is within the same
controlled group as Camco under Section
414(b), (c), (m) or (o) of the Code or
Section 4001 of ERISA (the "Camco Controlled
Group"), will be credited to such employees
or retirees for all purposes (other than
accrual of benefits), including vesting and
the eligibility to participate and receive
benefits for which a specified period of
service is required under such STC Group
employee benefit plan, program, policy or
arrangement.

(iii) Certain Welfare Plan Provisions. STC will
take, or cause the appropriate member of the
STC Group to take, such actions as are
necessary so that Continuing Employees and
Camco Retirees shall not be subject to
preexisting condition exclusions or waiting
periods

-39-
47
for welfare benefit plan coverages (except to
the extent so subject prior to the Effective
Time) under any STC Group welfare benefit
plan that is made available to them and shall
receive full credit for any copayments and
deductibles already incurred under the
comparable plan of Camco and its Subsidiaries
during the applicable plan year in which the
Effective Time occurs.

(d) Specific Agreements as to Employee Benefit Coverage
after the Effective Time. The following provisions
shall modify the obligations of the STC Group under
Section 5.14(c) to the extent set forth below.

(i) Severance Policies or Plans. For the period
commencing on the Effective Time and ending
on December 31, 1999, a Continuing Employee
who is not a party to an individual agreement
providing for the payment of severance
benefits shall be provided with continued
coverage under the Camco Benefit Plan
providing for severance benefit coverage to
the Continuing Employee at the Effective Time
or, if any member of the STC Group maintains
a severance plan that would otherwise cover
the Continuing Employee by its terms and such
plan would provide greater benefits to the
Continuing Employee, the employee instead
shall be provided with coverage under such
superior STC Group severance plan while
eligible for such plan during the period
commencing on the Effective Time and ending
on December 31, 1999. From and after January
1, 2000, for as long as the STC Group
maintains a severance plan for its Similarly
Situated Employees, a Continuing Employee who
is not a party to an individual severance
agreement shall be provided with coverage
under the STC Group severance plan.
Continuing Employees will accrue severance
plan credit at the same rate as Similarly
Situated Employees and, for this purpose,
years of service with the Camco Controlled
Group prior to the Effective Time will be
credited.

(ii) Management and Sales Incentive Compensation
Programs. The following provisions shall
apply to those Camco Benefit Plans that
provide for management and sales incentive
compensation and that are in effect at the
Effective Time. In the event that a
participant in an incentive compensation
program ceases to be an employee for any
reason other than termination for cause or
voluntary resignation, or in the event that a
participant is reassigned to a business unit
which is no longer within the Camco incentive
compensation measurements, the participant
will receive an incentive compensation
payment as measured against the plan at the
end of the prior quarter and based on an
annual award prorated for the fraction of the
year up to the change in employment status.
In the event that a reorganization results in
a

-40-
48
business unit being removed from the Camco
incentive compensation measurements, the
measurements of the plan will be adjusted to
eliminate the objectives of that business
unit from the performance evaluation for
calculation of incentive compensation
payments for the remaining business units.
Voluntary resignation shall not include
termination under Section 2(a) of a Camco
Executive Severance Agreement.

(iii) Qualified Defined Contribution Plans. No
Camco Benefit Plan that is a qualified
defined contribution pension plan shall be
terminated in a manner that would generate a
distributable event to a participant (unless
the corresponding plan(s) maintained by the
STC Group for Similarly Situated Employees
are also so terminated). The STC Group may
make employer contributions under qualified
defined contribution plans for Continuing
Employees at a rate or level that differ from
the contributions made under such plans for
Similarly Situated Employees based on the
relative profits of the STC Group operating
unit or division employing Continuing
Employees as compared to the profits of the
STC Group operating unit or division
employing Similarly Situated Employees.

(iv) Qualified Defined Benefit Plans.

(A) Freeze of Benefit Accruals.
Benefit accruals by a participant in any
Camco Benefit Plan that is a qualified
defined benefit pension plan (a "Camco
Defined Benefit Plan") may be frozen by a
member of the STC Group at any time on or
after the close of the calendar year in which
the Effective Time occurs, provided that the
definition for compensation includes covered
earnings up to the date the plan is frozen
and further provided that Continuing
Employees then commence accruing a benefit
under a qualified defined benefit pension
plan sponsored by a member of the STC Group
(a "STC Group Defined Benefit Plan") if
Similarly Situated Employees are then
accruing a benefit under such a plan. An ad
hoc benefit adjustment shall be made to the
frozen benefit attributable to the Camco
Defined Benefit Plan to the extent such an
adjustment is made under a STC Group Defined
Benefit Plan.

(B) Service Crediting. In the
event that the benefit accrual of a
Continuing Employee under a Camco Defined
Benefit Plan is frozen, or a Camco Defined
Benefit Plan is merged into a STC Group
Defined Benefit Plan, the following service
crediting provisions (in addition to any
service crediting provisions of Section
5.14(c) that are not inconsistent with this
paragraph) shall apply to any benefit

-41-
49
accrued after the Effective Time under such
STC Group Defined Benefit Plan: Continuing
Employees will be credited with service equal
to the employees' accrued vesting service
under the Camco Defined Benefit Plan for
periods prior to the Effective Time, for
purposes of vesting, eligibility to
participate, eligibility for enhanced levels
of benefit accrual and eligibility for early
retirement.

(C) Early Retirement.
Notwithstanding the foregoing, the early
retirement provisions of the Camco Defined
Benefit Plan that is merged into a STC Group
Defined Benefit Plan or under which the
accrued benefit of a Continuing Employee is
frozen shall continue to apply to the benefit
accrued under the provisions of the Camco
Defined Benefit Plan rather than the early
retirement provisions of the STC Group
Defined Benefit Plan. To the extent that a
Continuing Employee commences receipt of an
early retirement benefit under a STC Group
Defined Benefit Plan prior to the time that
the benefit accrued under a Camco Defined
Benefit Plan would be payable, the benefit
accrued under the Camco Defined Benefit Plan
shall nevertheless commence being paid at the
same time as the benefit under the STC Group
Defined Benefit Plan, but shall be
actuarially reduced to reflect such early
commencement.

(v) Retiree Medical Coverage. For so long as the
STC Group provides retiree medical coverage
to its eligible retiring Similarly Situated
Employees, retiree medical coverage under a
Camco Benefit Plan or a plan maintained by a
member of the STC Group shall be made
available to eligible Camco Retirees. The
STC Group may impose eligibility criteria of
attainment of age 60 during employment with
20 years of service (within the meaning of
the vesting service definition of the Camco
Benefit Plan that is a qualified defined
benefit pension plan and that covers the
employee at the Effective Time) for such
coverage, but no more restrictive eligibility
criteria unless such more restrictive
criteria also applies to Similarly Situated
Employees. However, a Continuing Employee
who, at the Effective Time, is age 55 and has
accrued 15 or more years of service shall be
eligible, upon an involuntary termination of
employment entitling the employee to benefits
under a STC Group or Camco severance plan or
agreement, for the same retiree medical
coverage provided to other Camco Retirees,
notwithstanding the age and service
eligibility criteria otherwise applicable for
retiree medical coverage. Camco Retirees may
be required to pay premiums for retiree
medical coverage up to, but not in excess of,
the highest premium permitted to be charged
for such continuation coverage under the
Consolidated Omnibus Budget

-42-
50
Reconciliation Act of 1986 unless higher
premiums also are required from Similarly
Situated Employees who retire.

(vii) U.K. Performance Related Pay (PRP) Plans.
Camco Benefit Plans that are PRP plans will
not be discontinued prior to the close of the
calendar year in which the Effective Time
occurs.

(viii) Health Care and Dependent Care Flexible
Spending Accounts. Camco Benefit Plans that
are flexible spending accounts within the
meaning of Code Section 125 and the
regulations thereunder will not be
discontinued prior to the close of the
calendar year in which the Effective Time
occurs.

(e) Vacation. With respect to the calendar year in which
the Effective Time occurs, a Continuing Employee will
be permitted to take vacation after the Effective
Time (in accordance with the STC Group vacation
policies generally applicable to Similarly Situated
Employees) for accrued and unused vacation days
(determined under the vacation policies of Camco)
that such Continuing Employee is entitled to use for
the calendar year in which the Effective Time occurs.
Continuing Employees shall receive pay in lieu of
such unused vacation time at the end of the calendar
year in which the Effective Time occurs. In
addition, with respect to vacation time that is
earned during the calendar year in which the
Effective Time occurs (which may be taken in the
subsequent calendar year under the vacation policies
of Camco) (the "Vacation Accrual"), the Vacation
Accrual shall, on the first day of such subsequent
calendar year, be credited to the Continuing
Employees' vacation credit accounts under the
applicable STC Group vacation policy for the calendar
year following the Effective Time, up to the maximum
allowed under the vacation policies of the STC Group,
and the Continuing Employees will be paid for any
Vacation Accrual in excess of such maximum.
Continuing Employees will, in addition to having
their Vacation Accrual credited as of the first day
of the calendar year following the Effective Time,
accrue vacation time for calendar years commencing on
and after the Effective Time at the same rate as
Similarly Situated Employees and, for this purpose,
years of service with the Camco Controlled Group
prior to the Effective Time will be credited.
Notwithstanding the foregoing, the total vacation
time credited to a Continuing Employee's vacation
credit account for the calendar year following the
Effective Time (both by the Vacation Accrual credit
made at the beginning of the year and vacation
accrued thereafter) shall not exceed the maximum
allowed under the applicable vacation policies of the
STC Group.

(f) Retention Bonus Program. Notwithstanding the
provisions of Section 4.1(h), STC agrees that Camco
may establish a retention bonus program for the

-43-
51
benefit of certain named Continuing Employees
