                                RIGHTS AGREEMENT

                  This Rights Agreement, dated as of November 20, 1992 as
amended and restated as of November 16, 2001 (the "Agreement"), between
Oceaneering International, Inc., a Delaware corporation (the "Company"), and
EquiServe Trust Company, N.A., a national banking association (the "Rights
Agent"),

                              W I T N E S S E T H:
                              --------------------

                  WHEREAS, on November 20, 1992 (the "Rights Dividend
Declaration Date"), the Board of Directors of the Company authorized and
declared a dividend of one Right for each share of common stock, par value $.25
per share, of the Company (the "Common Stock") outstanding at the close of
business on December 4, 1992 (the "Record Date"), and has authorized the
issuance of one Right (as such number may hereinafter be adjusted pursuant to
the provisions of Section 11(p) hereof) for each share of Common Stock of the
Company issued (whether originally issued or delivered from the Company's
treasury) between the Record Date and the earlier of the Distribution Date (as
hereinafter defined) and the Expiration Date (as hereinafter defined), and, in
certain circumstances provided for in Section 22 hereof, after the Distribution
Date, each Right initially representing the right to purchase one Fractional
Share (as hereinafter defined) of Series B Junior Participating Preferred Stock
of the Company, upon the terms and subject to the conditions hereinafter set
forth (the "Rights");

                  WHEREAS, the Company and the Rights Agent entered into a
Rights Agreement dated as of November 20, 1992 (the "Original Agreement") with
respect to the Rights; and

                  WHEREAS, the Company desires to make certain amendments to the
terms of the Original Agreement pursuant to Section 27 thereof and to restate
the Original Agreement;

                  NOW, THEREFORE, in consideration of the premises and the
mutual agreements herein set forth, the parties hereby agree as follows:

                  Section 1. Certain Definitions.  For purposes of this
Agreement, the following terms shall have the meanings indicated:

                  "Acquiring Person" shall mean any Person who or which,
together with all Affiliates and Associates of such Person, shall be the
Beneficial Owner of 15% or more of the shares of Common Stock then outstanding,
but shall not include any Exempt Person; provided, however, that a Person shall
not be or become an Acquiring Person if such Person, together with its
Affiliates and Associates, shall become the Beneficial Owner of 15% or more of
the shares of Common Stock then outstanding solely as a result of a reduction in
the number of shares of Common Stock outstanding due to the repurchase of Common
Stock by the Company, unless and until such time as such Person together with
its Affiliates and Associates shall purchase or otherwise become the Beneficial
Owner of additional shares of Common Stock constituting 1% or more of the then
outstanding shares of Common Stock or any other Person (or Persons) who is (or
collectively are) the Beneficial Owner of shares of Common Stock constituting 1%
or more of the then outstanding shares of Common Stock shall become an Affiliate
or Associate of such Person, unless, in either such case, such Person, together
with all Affiliates and Associates of


                                      -1-
<PAGE>
such Person, is not then the Beneficial Owner of 15% or more of the shares of
Common Stock then outstanding; and provided, further, that if the Board of
Directors determines in good faith that a Person that would otherwise be an
"Acquiring Person" has become such inadvertently (including, without limitation,
because (i) such Person was unaware that it beneficially owned a percentage of
Common Stock that would otherwise cause such Person to be an "Acquiring Person"
or (ii) such Person was aware of the extent of its Beneficial Ownership of
Common Stock but had no actual knowledge of the consequences of such Beneficial
Ownership under this Agreement) and without any intention of changing control of
the Company, and if such Person as promptly as practicable divested or divests
itself of Beneficial Ownership of a sufficient number of shares of Common Stock
so that such Person would no longer be an "Acquiring Person," then such Person
shall not be deemed to be or to have become an "Acquiring Person" for any
purposes of this Agreement.

                  Notwithstanding anything in this definition of "Acquiring
Person" to the contrary, if, as of the date hereof, any Person, together with
all Affiliates or Associates of such Person, is the Beneficial Owner of a number
of shares of Common Stock that would otherwise cause such Person to be an
Acquiring Person, such Person shall not be or become an Acquiring Person unless
and until such time as such Person or any Affiliate or Associate of such Person
shall purchase or otherwise become the Beneficial Owner of additional shares of
Common Stock constituting 1% or more of the then outstanding shares of Common
Stock or any other Person (or Persons) who is (or collectively are) the
Beneficial Owner of shares of Common Stock constituting 1% or more of the then
outstanding shares of Common Stock shall become an Affiliate or Associate of
such Person unless, in either such case, such Person, together with all
Affiliates and Associates of such Person, is not then the Beneficial Owner of a
number of shares that would otherwise cause such Person to be an Acquiring
Person.

                  At any time that the Rights are redeemable, the Board of
Directors may, generally or with respect to any specified Person or Persons,
determine to increase to a specified percentage or amount greater than that set
forth herein or decrease to a specified percentage or amount lower than that set
forth herein or determine a number of shares to be (but in no event less than or
equal to the percentage or number of shares of Common Stock then beneficially
owned by such Person), the level of Beneficial Ownership of Common Stock at
which a Person or such Person or Persons becomes an Acquiring Person.

                  "Adjustment Shares" shall have the meaning set forth in
Section 11(a)(ii) hereof.

                  "Affiliate" shall have the meaning ascribed to such term in
Rule 12b-2 of the General Rules and Regulations under the Exchange Act, as in
effect on the date of this Agreement.

                  "Associate" shall mean, with reference to any Person, (1) any
corporation, firm, partnership, association, unincorporated organization or
other entity (other than the Company or a Subsidiary of the Company) of which
such Person is an officer or general partner (or officer or general partner of a
general partner) or is, directly or indirectly, the Beneficial Owner of 10% or
more of any class of equity securities, (2) any trust or other estate in which
such Person has a substantial beneficial interest or as to which such Person
serves as trustee or in a similar

                                      -2-
<PAGE>

fiduciary capacity and (3) any relative or spouse of such Person, or any
relative of such spouse, who has the same home as such Person.

                  A Person shall be deemed the "Beneficial Owner" of, and shall
be deemed to "beneficially own," any securities:

                  (i) that such Person or any of such Person's Affiliates or
         Associates, directly or indirectly, is the "beneficial owner" of (as
         determined pursuant to Rule 13d-3 of the General Rules and Regulations
         under the Exchange Act as in effect on the date of this Agreement) or
         otherwise has the right to vote or dispose of, including pursuant to
         any agreement, arrangement or understanding (whether or not in
         writing); provided, however, that a Person shall not be deemed the
         "Beneficial Owner" of, or to "beneficially own," any security under
         this subparagraph (i) as a result of an agreement, arrangement or
         understanding to vote such security if such agreement, arrangement or
         understanding: (A) arises solely from a revocable proxy or consent
         given in response to a public (i.e., not including a solicitation
         exempted by Rule 14a-2(b)(2) of the General Rules and Regulations under
         the Exchange Act as in effect on the date of this Agreement) proxy or
         consent solicitation made pursuant to, and in accordance with, the
         applicable provisions of the General Rules and Regulations under the
         Exchange Act, (B) is not then reportable by such Person on Schedule 13D
         under the Exchange Act (or any comparable or successor report) and (C)
         does not constitute a trust, proxy, power of attorney or other device
         with the purpose or effect of allowing two or more persons, acting in
         concert, to avoid being deemed "beneficial owners" of such security or
         otherwise avoid the status of "Acquiring Person" under the terms of
         this Agreement or as part of a plan or scheme to evade the reporting
         requirements under Schedule 13D or Sections 13(d) or 13(g) of the
         Exchange Act;

                  (ii) that such Person or any of such Person's Affiliates or
         Associates, directly or indirectly, has the right or obligation to
         acquire (whether such right or obligation is exercisable or effective
         immediately or only after the passage of time or the occurrence of an
         event) pursuant to any agreement, arrangement or understanding (whether
         or not in writing) or upon the exercise of conversion rights, exchange
         rights, other rights, warrants or options, or otherwise; provided,
         however, that a Person shall not be deemed the "Beneficial Owner" of,
         or to "beneficially own," (A) securities tendered pursuant to a tender
         or exchange offer made by such Person or any of such Person's
         Affiliates or Associates until such tendered securities are accepted
         for purchase or exchange, (B) securities issuable upon exercise of
         Rights at any time prior to the occurrence of a Triggering Event, or
         (C) securities issuable upon exercise of Rights from and after the
         occurrence of a Triggering Event which Rights were acquired by such
         Person or any of such Person's Affiliates or Associates prior to the
         Distribution Date or pursuant to Section 3(a) or Section 22 hereof (the
         "Original Rights") or pursuant to Section 11(i) or (p) hereof in
         connection with an adjustment made with respect to any Original Rights;
         or

                  (iii) that are beneficially owned, directly or indirectly, by
         (A) any other Person (or any Affiliate or Associate thereof) with which
         such Person or any of such Person's Affiliates or Associates has any
         agreement, arrangement or understanding (whether or not in writing) for
         the purpose of acquiring, holding, voting (except pursuant to a
         revocable

                                      -3-

         proxy or consent as described in the proviso to subparagraph (i) of
         this definition) or disposing of any voting securities of the Company
         or (B) any group (as that term is used in Rule 13d-5(b) of the General
         Rules and Regulations under the Exchange Act, as in effect on the date
         of this Agreement) of which such Person is a member;

provided, however, that nothing in this definition shall cause a Person engaged
in business as an underwriter of securities to be the "Beneficial Owner" of, or
to "beneficially own," any securities acquired through such Person's
participation in good faith in a firm commitment underwriting (including,
without limitation, securities acquired pursuant to stabilizing transactions to
facilitate a public offering in accordance with Regulation M promulgated under
the Exchange Act, or to cover overallotments created in connection with a public
offering) until the expiration of forty days after the date of such acquisition.
For purposes of this Agreement, "voting" a security shall include voting,
granting a proxy, acting by consent, making a request or demand relating to
corporate action (including, without limitation, calling a stockholder meeting),
entering into a voting trust or voting agreement or otherwise giving an

Exchange, or, if such security is not listed or admitted to trading on the New
York Stock Exchange, on the principal national securities exchange on which such
security is listed or admitted to trading, or, if such security is not listed or
admitted to trading on any national securities exchange but sales price
information is reported for such security, as reported by NASDAQ or such other
self-regulatory organization or registered securities information processor (as
such terms are used under the Exchange Act) that then reports information

                  Section 2. Appointment of Rights Agent. The Company hereby
appoints the Rights Agent (i) to act as agent for the Company and (ii) to take
certain actions in respect of the holders of the Rights (who, in accordance with
Section 3 hereof, shall prior to the Distribution Date also be the holders of
the Common Stock) (although it is expressly agreed that the Rights Agent shall
not act as agent for such holders) in accordance with the terms and conditions
hereof, and the Rights Agent hereby accepts such appointment. The Company may
from time to time appoint such Co-Rights Agents as it may deem necessary or
desirable upon ten days prior written notice to the Rights Agent. The Rights
Agent shall have no duty to supervise, and shall in no event be liable for the
acts or omissions of any such Co-Rights Agent.

                  Section 3. Issue of Rights Certificates.

                  (a) Until the Distribution Date, (x) the Rights will be
evidenced (subject to the provisions of paragraph (b) of this Section 3) by the
certificates for Common Stock registered in the names of the holders of the
Common Stock and not by separate certificates, and (y) the Rights will be
transferable only in connection with the transfer of the underlying shares of
Common Stock (including a transfer to the Company). As soon as practicable after
the Distribution Date, the Rights Agent will send by first-class, insured,
postage prepaid mail, to each record holder of the Common Stock as of the close
of business on the Distribution Date (other than any Person referred to in the
first sentence of Section 7(e)), at the address of such holder shown on the
records of the Company, one or more Rights Certificates, evidencing one Right
for each share of Common Stock so held, subject to adjustment as provided
herein. In the event that an adjustment in the number of Rights per share of
Common Stock has been made pursuant to Section 11(p) hereof, at the time of
distribution of the Rights Certificates, the Company shall make the necessary
and appropriate rounding adjustments (in accordance with Section 14(a) hereof)
so that Rights Certificates representing only whole numbers of Rights are
distributed and cash is paid in lieu of any fractional Rights. As of and after
the Distribution Date, the Rights will be evidenced solely by such Rights
Certificates.

                  (b) Promptly following the Record Date, the Company sent a
copy of a Summary of Rights, in substantially the form attached to the Original
Agreement as Exhibit C, by first-class, postage prepaid mail, to each record
holder of Common Stock as of the close of business on the Record Date, at the
address of such holder shown on the records of the Company. With respect to
certificates for Common Stock outstanding as of the Record Date, until the
Distribution Date or the earlier surrender for transfer thereof or the
Expiration Date, the Rights associated with the shares of Common Stock
represented by such certificates shall be evidenced by such certificates for
Common Stock together with the Summary of Rights, and the registered holders of
the Common Stock shall also be the registered holders of the associated Rights.
Until the earlier of the Distribution Date or the Expiration Date, the transfer
of any of the certificates for Common Stock outstanding on the Record Date, with
or without a copy of the Summary of Rights, shall also constitute the transfer
of the Rights associated with the Common Stock represented by such certificates.

                  (c) Rights have been and shall be issued in respect of all
shares of Common Stock that have been or are issued (whether originally issued
or delivered from the Company's treasury) after the Record Date but prior to the
earlier of the Distribution Date or the Expiration Date or, in certain
circumstances provided in Section 22 hereof, after the Distribution Date.

                                      -8-
<PAGE>
Certificates issued representing such shares of Common Stock that shall so
become outstanding or shall be transferred or exchanged after the Record Date
but prior to the earlier of the Distribution Date or the Expiration Date shall
also be deemed to be certificates for Rights, and shall bear either the legend
set forth in Section 3(c) of the Original Agreement or the following legend:

                  This certificate also evidences and entitles the holder hereof
         to certain Rights as set forth in the Rights Agreement between
         Oceaneering International, Inc. (the "Company") and EquiServe Trust
         Company, N.A. (the "Rights Agent") dated as of November 20, 1992 as
         amended and restated as of November 16, 2001 as it may from time to
         time be further supplemented or amended (the "Rights Agreement"), the
         terms of which are hereby incorporated herein by reference and a copy
         of which is on file at the principal offices of the Company. Under
         certain circumstances, as set forth in the Rights Agreement, such
         Rights may be redeemed, may be exchanged, may expire or may be
         evidenced by separate certificates and will no longer be evidenced by
         this certificate. The Company will mail to the holder of this
         certificate a copy of the Rights Agreement, as in effect on the date of
         mailing, without charge promptly after receipt of a written request
         therefor. UNDER CERTAIN CIRCUMSTANCES SET FORTH IN THE RIGHTS
         AGREEMENT, RIGHTS BENEFICIALLY OWNED BY OR TRANSFERRED TO ANY PERSON
         WHO IS, WAS OR BECOMES AN ACQUIRING PERSON OR AN AFFILIATE OR ASSOCIATE
         THEREOF (AS SUCH TERMS ARE DEFINED IN THE RIGHTS AGREEMENT), AND
         CERTAIN TRANSFEREES THEREOF, WILL BECOME NULL AND VOID AND WILL NO
         LONGER BE TRANSFERABLE.

With respect to such certificates containing the foregoing legend, until the
earlier of the Distribution Date or the Expiration Date, the Rights associated
with the Common Stock represented by such certificates shall be evidenced by
such certificates alone, and registered holders of Common Stock shall also be
the registered holders of the associated Rights, and the transfer of any of such
certificates shall also constitute the transfer of the Rights associated with
the Common Stock represented by such certificates.

                  Section 4. Form of Rights Certificates.

                  (a) The Rights Certificates (and the forms of election to
purchase and of assignment to be printed on the reverse thereof), when, as and
if issued, shall be substantially in the form set forth in Exhibit B hereto and
may have such marks of identification or designation and such legends, summaries
or endorsements printed thereon as the Company may deem appropriate and as are
not inconsistent with the provisions of this Agreement, or as may be required to
comply with any applicable law or with any rule or regulation made pursuant
thereto or with any rule or regulation of any stock exchange or quotation system
on which the Rights may from time to time be listed or quoted, or to conform to
usage. Subject to the provisions of Section 11 and Section 22 hereof, the Rights
Certificates, whenever issued, shall be dated as of the Record Date and on their
face shall entitle the holders thereof to purchase such number of Fractional
Shares of Preferred Stock as shall be set forth therein at the price set forth
therein (such exercise price per Fractional Share (or, as set forth in this
Agreement, for other securities), the "Purchase Price"), but the amount and type
of securities purchasable upon the exercise of each Right and the Purchase Price
thereof shall be subject to adjustment as provided herein.

                  (b) Any Rights Certificate issued pursuant to Section 3(a) or
Section 22 hereof that represents Rights beneficially owned by a Person
described in the first sentence of Section 7(e), and any Rights Certificate
issued pursuant to Section 6 or Section 11 hereof upon transfer, exchange,
replacement or adjustment of any such Rights, shall contain (to the extent
feasible) the following legend, modified as applicable to apply to such Person:

         The Rights represented by this Rights Certificate are or were
         beneficially owned by a Person who was or became an Acquiring Person or
         an Affiliate or Associate of an Acquiring Person (as such terms are
         defined in the Rights Agreement). Accordingly, this Rights Certificate
         and the Rights represented hereby [will] [have] become null and void in
         the circumstances and with the effect specified in Section 7(e) of such
         Agreement.

The provisions of Section 7(e) of this Agreement shall be operative whether or
not the foregoing legend is contained on any such Rights Certificate. The
Company shall give notice to the Rights Agent promptly after it becomes aware of
the existence of any Acquiring Person or any Associate or Affiliate thereof.

                  Section 5. Countersignature and Registration.

                  (a) The Rights Certificates shall be executed on behalf of the
Company by its Chairman of the Board, its President or any Vice President,
either manually or by facsimile signature, and shall have affixed thereto the
Company's seal or a facsimile thereof, which shall be attested by the Secretary
or an Assistant Secretary of the Company, either manually or by facsimile
signature. The Rights Certificates shall be countersigned by the Rights Agent,
either manually or by facsimile signature, and shall not be valid for any
purpose unless so countersigned. In case any officer of the Company who shall
have signed any of the Rights Certificates shall cease to be such officer of the
Company before countersignature by the Rights Agent and issuance and delivery by
the Company, such Rights Certificates, nevertheless, may be countersigned by the
Rights Agent and issued and delivered by the Company with the same force and
effect as though the person who signed such Rights Certificates had not ceased
to be such officer of the Company; and any Rights Certificate may be signed on
behalf of the Company by any person who, at the actual date of the execution of
such Rights Certificate, shall be a proper officer of the Company to sign such
Rights Certificate, although at the date of the execution of this Rights
Agreement any such person was not such an officer.

                  (b) Following the Distribution Date, the Rights Agent will
keep or cause to be kept, at its principal office or offices designated as the
appropriate place for surrender of Rights Certificates upon exercise or
transfer, books for registration and transfer of the Rights Certificates issued
hereunder. Such books shall show the names and addresses of the respective
holders of the Rights Certificates, the number of Rights evidenced on its face
by each of the Rights Certificates and the certificate number and the date of
each of the Rights Certificates.

                  Section 6. Transfer, Split-Up, Combination and Exchange of
Rights Certificates; Mutilated, Destroyed, Lost or Stolen Rights Certificates.

                  (a) Subject to the provisions of Section 4(b), Section 7(e),
Section 13(d), Section 14 and Section 24 hereof, at any time after the close of
business on the Distribution Date, and at or prior to the close of business on
the Expiration Date, any Rights Certificate or Rights Certificates may be
transferred, split up, combined or exchanged for another Rights Certificate or
Rights Certificates, entitling the registered holder to purchase a like number
of Fractional Shares of Preferred Stock (or, following a Triggering Event,
Common Stock, other securities, cash or other assets, as the case may be) as the
Rights Certificate or Rights Certificates surrendered then entitled such holder
(or former holder in the case of a transfer) to purchase. Any registered holder
desiring to transfer, split up, combine or exchange any Rights Certificate or
Rights Certificates shall make such request in writing delivered to the Rights
Agent, and shall surrender the Rights Certificate or Rights Certificates to be
transferred, split up, combined or exchanged at the principal office or offices
of the Rights Agent designated for such purpose. Neither the Rights Agent nor
the Company shall be obligated to take any action whatsoever with respect to the
transfer of any such surrendered Rights Certificate until the registered holder
shall have completed and signed the certificate contained in the form of
assignment on the reverse side of such Rights Certificate and shall have
provided such additional evidence of the identity of the Beneficial Owner (or
former Beneficial Owner) thereof or of the Affiliates or Associates thereof as
the Company shall reasonably request. Thereupon the Rights Agent shall, subject
to Section 4(b), Section 7(e), Section 13(d), Section 14 and Section 24 hereof,
countersign and deliver to the Person entitled thereto a Rights Certificate or
Rights Certificates, as the case may be, as so requested. The Company may
require payment by the holder of a sum sufficient to cover any tax or
governmental charge that may be imposed in connection with any transfer,
split-up, combination or exchange of Rights Certificates.

                  (b) Upon receipt by the Company and the Rights Agent of
evidence reasonably satisfactory to them of the loss, theft, destruction or
mutilation of a Rights Certificate, and, in case of loss, theft or destruction,
of indemnity or security reasonably satisfactory to them, and reimbursement to
the Company and the Rights Agent of all reasonable expenses incidental thereto,
and upon surrender to the Rights Agent and cancellation of the Rights
Certificate if mutilated, the Company will, subject to Section 4(b), Section
7(e), Section 13(d), Section 14 and Section 24, execute and deliver a new Rights
Certificate of like tenor to the Rights Agent for countersignature and delivery
to the registered owner in lieu of the Rights Certificate so lost, stolen,
destroyed or mutilated.

                  Section 7. Exercise of Rights; Purchase Price.

                  (a) Subject to Section 7(e) hereof, the registered holder of
any Rights Certificate may exercise the Rights evidenced thereby (except as
otherwise provided herein including, without limitation, the restrictions on
exercisability set forth in Section 9(c), Section 11(a)(iii) and Section 23(a)
hereof) in whole or in part at any time after the Distribution Date upon
surrender of the Rights Certificate, with the form of election to purchase and
the certificate on the reverse side thereof duly completed and executed, to the
Rights Agent at the principal office or offices of the Rights Agent designated
for such purpose, together with payment of the aggregate Purchase Price with
respect to the total number of Fractional Shares of Preferred Stock

                                      -11-
<PAGE>
(or other securities, cash or other assets, as the case may be) as to which such
surrendered Rights are then exercisable, at or prior to the Expiration Date.

                  (b) The Purchase Price for each Fractional Share of Preferred
Stock pursuant to the exercise of a Right shall initially be $60, and shall be
subject to adjustment from time to time as provided in Sections 11 and 13(a)
hereof and shall be payable in accordance with paragraph (c) below.

                  (c) Upon receipt of a Rights Certificate representing
exercisable Rights, with the form of election to purchase and the certificate on
the reverse side thereof duly executed, accompanied by payment, with respect to
each Right so exercised, of the Purchase Price per Fractional Share of Preferred
Stock (or other shares, securities, cash or other assets, as the case may be) to
be purchased as set forth below and an amount equal to any applicable transfer
tax, the Rights Agent shall, subject to Section 20(k) hereof, thereupon promptly
(i)(A) requisition from any transfer agent of the shares of Preferred Stock (or
make available, if the Rights Agent is the transfer agent for such shares)
certificates for the total number of Fractional Shares of Preferred Stock to be
purchased, and the Company hereby irrevocably authorizes its transfer agent to
comply with all such requests, or (B) if the Company, in its sole discretion,
shall have elected to deposit the shares of Preferred Stock issuable upon
exercise of the Rights hereunder with a depositary agent, requisition from the
depositary agent depositary receipts representing interests in such number of
Fractional Shares of Preferred Stock as are to be purchased (in which case
certificates for the shares of Preferred Stock represented by such receipts
shall be deposited by the transfer agent with the depositary agent) and the
Company will direct the depositary agent to comply with such request, (ii)
requisition from the Company the amount of cash, if any, to be paid in lieu of
fractional shares in accordance with Section 14 hereof, (iii) after receipt of
such certificates or depositary receipts, cause the same to be delivered to or
upon the order of the registered holder of such Rights Certificate, registered
in such name or names as may be designated by such holder and (iv) after receipt
thereof, deliver such cash, if any, to or upon the order of the registered
holder of such Rights Certificate. The payment of the Purchase Price (as such
amount may be reduced pursuant to Section 11(a)(iii) hereof) may be made in cash
or by certified check, cashier's or official bank check or bank draft payable to
the order of the Company or the Rights Agent. In the event that the Company is
obligated to issue other securities (including Common Stock) of the Company, pay
cash and/or distribute other property pursuant to Section 11(a) or Section 13(a)
hereof, the Company will make all arrangements necessary so that such other
securities, cash and/or other property are available for distribution by the
Rights Agent, if and when appropriate. The Company reserves the right to require
prior to the occurrence of a Triggering Event that, upon exercise of Rights, a
number of Rights be exercised so that only whole shares of Preferred Stock would
be issued.

                  (d) In case the registered holder of any Rights Certificate
shall exercise fewer than all the Rights evidenced thereby, a new Rights
Certificate evidencing Rights equivalent to the Rights remaining unexercised
shall be issued by the Rights Agent and delivered to, or upon the order of, the
registered holder of such Rights Certificate, registered in such name or names
as may be designated by such holder, subject to the provisions of Section 14
hereof.

                  (e) Notwithstanding anything in this Agreement to the
contrary, from and after the first occurrence of a Triggering Event, any Rights
beneficially owned by or transferred

                                      -12-
<PAGE>
to (i) an Acquiring Person or an Associate or Affiliate of an Acquiring Person
other than any such Person that became such pursuant to a Permitted Offer and
the Board of Directors in good faith determines was not involved in and did not
cause or facilitate, directly or indirectly, such Triggering Event, (ii) a
direct or indirect transferee of such Rights from such Acquiring Person (or any
such Associate or Affiliate) who becomes a transferee after such Triggering
Event or (iii) a direct or indirect transferee of such Acquiring Person (or of
any such Associate or Affiliate) who becomes a transferee prior to or
concurrently with such Triggering Event and receives such Rights pursuant to
either (A) a transfer (whether or not for consideration) from such Acquiring
Person (or such Affiliate or Associate) to holders of equity interests in such
Acquiring Person (or such Affiliate or Associate) or to any Person with whom
such Acquiring Person (or such Affiliate or Associate) has any continuing
agreement, arrangement or understanding regarding the transferred Rights or (B)
a transfer that the Board of Directors of the Company determines is part of a
plan, arrangement or understanding that has as a primary purpose or effect the
avoidance of this Section 7(e), shall become null and void without any further
action, no holder of such Rights shall have any rights whatsoever with respect
to such Rights, whether under any provision of this Agreement or otherwise, and
such Rights shall not be transferable. The Company shall use all reasonable
efforts to ensure that the provisions of this Section 7(e) and Section 4(b)
hereof are complied with, but shall have no liability to any holder of Rights
Certificates or other Person as a result of its failure to make any
determinations with respect to an Acquiring Person or its Affiliates, Associates
or transferees hereunder.

                  (f) Notwithstanding anything in this Agreement to the
contrary, neither the Rights Agent nor the Company shall be obligated to
undertake any action with respect to a registered holder upon the occurrence of
any purported exercise as set forth in this Section 7 unless such registered
holder shall have (i) completed and signed the certificate contained in the form
of election to purchase set forth on the reverse side of the Rights Certificate
surrendered for such exercise and (ii) provided such additional evidence of the
identity of the Beneficial Owner (or former Beneficial Owner) or Affiliates or
Associates thereof as the Company shall reasonably request.

                  Section 8. Cancellation and Destruction of Rights
Certificates. All Rights Certificates surrendered for the purpose of exercise,
transfer, split-up, combination or exchange shall, if surrendered to the Company
or any of its agents, be delivered to the Rights Agent for cancellation or in
canceled form, or, if surrendered to the Rights Agent, shall be canceled by it,
and no Rights Certificates shall be issued in lieu thereof except as expressly
permitted by any of the provisions of this Agreement. The Company shall deliver
to the Rights Agent for cancellation and retirement, and the Rights Agent shall
so cancel and retire, any other Rights Certificate purchased or acquired by the
Company otherwise than upon the exercise thereof. The Rights Agent shall deliver
all canceled Rights Certificates to the Company, or shall, at the written
request of the Company, destroy such canceled Rights Certificates, and in such
case shall deliver a certificate of destruction thereof to the Company.

                  Section 9. Reservation and Availability of Capital Stock.

                  (a) The Company covenants and agrees that it will cause to be
reserved and kept available out of its authorized and unissued shares, or out of
its authorized and issued shares held in its treasury, the number of shares of
Preferred Stock (and, following the occurrence of a

                                      -13-
<PAGE>
Triggering Event, Common Stock and/or :other securities) that, as provided in
this Agreement, including Section 11(a)(iii) hereof, will be sufficient to
permit the exercise in full of all outstanding Rights.

                  (b) So long as any shares of Preferred Stock (and, following
the occurrence of a Triggering Event, Common Stock and/or other securities)
issuable and deliverable upon the exercise of the Rights are listed on any
national securities exchange or quoted on any trading system, the Company shall
use its best efforts to cause, from and after such time as the Rights become
exercisable, all shares reserved for such issuance to be listed on such
exchange, or quoted on such system, upon official notice of issuance upon such
exercise. Following the occurrence of a Triggering Event, the Company will use
its best efforts to list (or continue the listing of) the Rights and the
securities issuable and deliverable upon the exercise of the Rights on one or
more national securities exchanges or to cause the Rights and the securities
purchasable upon exercise of the Rights to be reported by NASDAQ or such other
transaction reporting system then in use.

                  (c) The Company shall use its best efforts to (i) prepare and
file, as soon as practicable following the first occurrence of a Flip-In Event
or, if applicable, as soon as practicable following the earliest date after the
first occurrence of a Flip-In Event on which the consideration to be delivered
by the Company upon exercise of the Rights has been determined pursuant to this
Agreement (including in accordance with Section 11(a)(iii) hereof), a
registration statement on an appropriate form under the Securities Act with
respect to the securities purchasable upon exercise of the Rights, (ii) cause
such registration statement to become effective as soon as practicable after
such filing, and (iii) cause such registration statement to remain effective
(with a prospectus at all times meeting the requirements of the Securities Act)
until the earlier of (A) the date as of which the Rights are no longer
exercisable for such securities and (B) the Expiration Date. The Company will
also take such action as may be appropriate under, or to ensure compliance with,
the securities or "blue sky" laws of the various states in connection with the
exercisability of the Rights. The Company may temporarily suspend, for a period
of time not to exceed 90 days after the date set forth in clause (i) of the
first sentence of this Section 9(c), the exercisability of the Rights in order
to prepare and file such registration statement and permit it to become
effective. In addition, if the Company shall determine that the Securities Act
requires an effective registration statement under the Securities Act following
the Distribution Date, the Company may temporarily suspend the exercisability of
the Rights until such time as such a registration statement has been declared
effective. Upon any such suspension, the Company shall issue a public
announcement stating that the exercisability of the Rights has been temporarily
suspended, as well as a public announcement at such time as the suspension is no
longer in effect. Notwithstanding any provision of this Agreement to the
contrary, the Rights shall not be exercisable in any jurisdiction if the
requisite qualification in such jurisdiction shall not have been obtained, the
exercise thereof shall not be permitted under applicable law or any required
registration statement shall not have been declared effective.

                  (d) The Company covenants and agrees that it will take all
such action as may be necessary to ensure that all Fractional Shares of
Preferred Stock (and, following the occurrence of a Triggering Event, Common
Stock and/or other securities) delivered upon exercise of Rights shall, at the
time of delivery of the certificates for such shares (subject to

                                      -14-
<PAGE>
payment of the Purchase Price), be duly and validly authorized and issued and
fully paid and nonassessable.

                  (e) The Company further covenants and agrees that it will pay
when due and payable any and all federal and state transfer taxes and charges
that may be payable in respect of the issuance or delivery of the Rights
Certificates and of any certificates for a number of Fractional Shares of
Preferred Stock (or Common Stock and/or other securities, as the case may be)
upon the exercise of Rights. The Company shall not, however, be required to pay
any transfer tax that may be payable in respect of any transfer or delivery of
Rights Certificates to a Person other than, or the issuance or delivery of a
number of Fractional Shares of Preferred Stock (or Common Stock and/or other
securities, as the case may be) in respect of a name other than that of, the
registered holder of the Rights Certificates evidencing Rights surrendered for
exercise or to issue or deliver any certificates for a number of Fractional
Shares of Preferred Stock (or Common Stock and/or other securities, as the case
may be) in a name other than that of the registered holder upon the exercise of
any Rights until such tax shall have been paid (any such tax being payable by
the holder of such Rights Certificate at the time of surrender) or until it has
been established to the Company's satisfaction that no such tax is due.

                  Section 10. Preferred Stock Record Date. Each Person in whose
name any certificate for a number of Fractional Shares of Preferred Stock (or
Common Stock and/or other securities, as the case may be) is issued upon the
exercise of Rights shall for all purposes be deemed to have become the holder of
record of such shares (fractional or otherwise) of Preferred Stock (or Common
Stock and/or other securities, as the case may be) represented thereby on, and
such certificate shall be dated, the date upon which the Rights Certificate
evidencing such Rights was duly surrendered and payment of the Purchase Price
(and all applicable transfer taxes) was made; provided, however, that if the
date of such surrender and payment is a date upon which the Preferred Stock (or
Common Stock and/or other securities, as the case may be) transfer books of the
Company are closed, such Person shall be deemed to have become the record holder
of such shares (fractional or otherwise) on, and such certificate shall be
dated, the next succeeding Business Day on which the Preferred Stock (or Common
Stock and/or other securities, as the case may be) transfer books of the Company
are open. Prior to the exercise of the Rights evidenced thereby, the holder of a
Rights Certificate, as such, shall not be entitled to any rights of a
stockholder of the Company with respect to shares for which the Rights shall be
exercisable, including, without limitation, the right to vote, to receive
dividends or other distributions or to exercise any preemptive rights, and shall
not be entitled to receive any notice of any proceedings of the Company, except
as provided herein.

                  Section 11. Adjustment of Purchase Price, Number and Kind of
Shares or Number of Rights. The Purchase Price, the number and kind of shares or
other securities subject to purchase upon exercise of each Right and the number
of Rights outstanding are subject to adjustment from time to time as provided in
this Section 11.

                  (a) (i) In the event the Company shall at any time after the
         Rights Dividend Declaration Date (A) declare a dividend on the
         outstanding shares of Preferred Stock payable in shares of Preferred
         Stock, (B) subdivide the outstanding shares of Preferred Stock, (C)
         combine the outstanding shares of Preferred Stock into a smaller number
         of shares or (D) otherwise reclassify the outstanding shares of
         Preferred Stock

                                      -15-
<PAGE>
         (including any such reclassification in connection with a consolidation
         or merger in which the Company is the continuing or surviving
         corporation), except as otherwise provided in this Section 11(a) and
         Section 7(e) hereof, the Purchase Price in effect at the time of the
         record date for such dividend or of the effective date of such
         subdivision, combination or reclassification, and the number and kind
         of shares of Preferred Stock or capital stock or other securities, as
         the case may be, issuable on such date, shall be proportionately
         adjusted so that the holder of any Right exercised after such time
         shall be entitled to receive, upon payment of the Purchase Price then
         in effect, the aggregate number and kind of shares of Preferred Stock
         or capital stock or other securities, as the case may be, which, if
         such Right had been exercised immediately prior to such date and at a
         time when the Preferred Stock transfer books of the Company were open,
         he would have owned upon such exercise and been entitled to receive by
         virtue of such dividend, subdivision, combination or reclassification.
         If an event occurs that would require an adjustment under both this
         Section 11(a)(i) and Section 11(a)(ii) hereof, the adjustment provided
         for in this Section 11(a)(i) shall be in addition to, and shall be made
         prior to, any adjustment required pursuant to Section 11(a)(ii) hereof.

                   (ii) Subject to Sections 23 and 24 of this Agreement, in the
         event any Person shall, at any time after the Rights Dividend
         Declaration Date, become an Acquiring Person, unless the event causing
         such Person to become an Acquiring Person is (1) a Flip-Over Event or
         (2) an acquisition of shares of Common Stock pursuant to a Permitted
         Offer (provided that this clause (2) shall cease to apply if such
         Acquiring Person thereafter becomes the Beneficial Owner of any
         additional shares of Common Stock other than pursuant to such Permitted
         Offer or a transaction set forth in Section 13(a) or 13(d) hereof),
         then (x) the Purchase Price shall be adjusted to be the Purchase Price
         immediately prior to the first occurrence of a Flip-In Event multiplied
         by the number of Fractional Shares of Preferred Stock for which a Right
         was exercisable immediately prior to such first occurrence and (y) each
         holder of a Right (except as provided below in Section 11(a)(iii) and
         in Section 7(e) hereof) shall thereafter have the right to receive,
         upon exercise thereof at a price equal to the Purchase Price in
         accordance with the terms of this Agreement, in lieu of the shares of
         Preferred Stock otherwise purchasable thereunder, such number of shares
         of Common Stock of the Company as shall equal the result obtained by
         dividing the Purchase Price by 50% of the Current Market Price per
         share of Common Stock on the date of such first occurrence (such number
         of shares, the "Adjustment Shares"); provided that the Purchase Price
         and the number of Adjustment Shares shall be further adjusted as
         provided in this Agreement to reflect any events occurring after the
         date of such first occurrence.

                  (iii) In the event that the number of shares of Common Stock
         that are authorized by the Company's certificate of incorporation but
         not outstanding or reserved for issuance for purposes other than upon
         exercise of the Rights is not sufficient to permit the exercise in full
         of the Rights in accordance with the foregoing subparagraph (ii) of
         this Section 11(a), the Company shall, to the extent permitted by
         applicable law and regulation, (A) determine the excess of (1) the
         value of the Adjustment Shares issuable upon the exercise of a Right
         (computed using the Current Market Price used to determine the number
         of Adjustment Shares) (the "Current Value") over (2) the Purchase Price
         (such excess is herein referred to as the "Spread"), and (B) with
         respect to each Right,

                                      -16-
<PAGE>
         make adequate provision to substitute for the Adjustment Shares, upon
         the exercise of the Rights and payment of the applicable Purchase
         Price, (1) cash, (2) a reduction in the Purchase Price, (3) Common
         Stock or other equity securities of the Company (including, without
         limitation, shares, or units of shares, of preferred stock (including,
         without limitation, the Preferred Stock) that the Board of Directors of
         the Company has determined to have the same value as shares of Common
         Stock (such shares of preferred stock are herein referred to as "Common
         Stock Equivalents")), (4) debt securities of the Company, (5) other
         assets or (6) any combination of the foregoing, having an aggregate
         value equal to the Current Value, where such aggregate value has been
         determined by the Board of Directors of the Company based upon the
         advice of a nationally recognized investment banking firm selected by
         the Board of Directors of the Company; provided, however, if the
         Company shall not have made adequate provision to deliver value
         pursuant to clause (B) above within 30 days following the later of (x)
         the first occurrence of a Flip-In Event and (y) the date on which the
         Company's right of redemption pursuant to Section 23(a) expires (the
         later of (x) and (y) being referred to herein as the "Flip-In Trigger
         Date"), then the Company shall be obligated to deliver, upon the
         surrender for exercise of a Right and without requiring payment of the
         Purchase Price, shares of Common Stock (to the extent available) and
         then, if necessary, cash, which shares and/or cash have an aggregate
         value equal to the Spread. If the Board of Directors of the Company
         shall determine in good faith that it is likely that sufficient
         additional shares of Common Stock could be authorized for issuance upon
         exercise in full of the Rights, the 30-day period set forth above may
         be extended to the extent necessary, but not more than 90 days after
         the Flip-In Trigger Date, in order that the Company may seek
         stockholder approval for the authorization of such additional shares
         (such period, as it may be extended, the "Substitution Period"). To the
         extent that the Company or the Board of Directors determines that some
         action need be taken pursuant to the first and/or second sentences of
         this Section 11(a)(iii), the Company (x) shall provide, subject to
         Section 7(e) hereof, that such action shall apply uniformly to all
         outstanding Rights, and (y) may suspend the exercisability of the
         Rights until the expiration of the Substitution Period in order to seek
         any authorization of additional shares and/or to decide the appropriate
         form of distribution to be made pursuant to such first sentence and to
         determine the value thereof. In the event of any such suspension, the
         Company shall issue a public announcement stating that the
         exercisability of the Rights has been temporarily suspended, as well as
         a public announcement at such time as the suspension is no longer in
         effect. For purposes of this Section 11(a)(iii), the value of the
         Common Stock shall be the Current Market Price per share of the Common
         Stock on the Flip-In Trigger Date and the value of any Common Stock
         Equivalent shall be deemed to have the same value as the Common Stock
         on such date.

                  (b) In case the Company shall fix a record date for the
issuance of rights, options or warrants to all holders of Preferred Stock
entitling them to subscribe for or purchase (for a period expiring within 45
calendar days after such record date) Preferred Stock (or shares having
substantially the same rights, privileges and preferences as the shares of
Preferred Stock ("Equivalent Preferred Stock")) or securities convertible into
Preferred Stock or Equivalent Preferred Stock at a price per share of Preferred
Stock or per share of Equivalent Preferred Stock (or having a conversion price
per share, if a security convertible into Preferred Stock or Equivalent
Preferred Stock) less than the Current Market Price per share of Preferred Stock
on

                                      -17-
<PAGE>
such record date, the Purchase Price to be in effect after such record date
shall be determined by multiplying the Purchase Price in effect immediately
prior to such record date by a fraction, the numerator of which shall be the
number of shares of Preferred Stock outstanding on such record date, plus the
number of shares of Preferred Stock that the aggregate offering price of the
total number of shares of Preferred Stock and/or Equivalent Preferred Stock so
to be offered (and/or the aggregate initial conversion price of the convertible
securities so to be offered) would purchase at such Current Market Price, and
the denominator of which shall be the number of shares of Preferred Stock
outstanding on such record date, plus the number of additional shares of
Preferred Stock and/or Equivalent Preferred Stock to be offered for subscription
or purchase (or into which the convertible securities so to be offered are
initially convertible). In case such subscription price may be paid by delivery
of consideration, part or all of which may be in a form other than cash, the
value of such consideration shall be as determined in good faith by the Board of
Directors of the Company, whose determination shall be described in a statement
filed with the Rights Agent and shall be binding on the Rights Agent and the
holders of the Rights. Shares of Preferred Stock owned by or held for the
account of the Company shall not be deemed outstanding for the purpose of any
such computation. Such adjustment shall be made successively whenever such a
record date is fixed, and in the event that such rights or warrants are not so
issued, the Purchase Price shall be adjusted to be the Purchase Price that would
then be in effect if such record date had not been fixed.

                  (c) In case the Company shall fix a record date for a
distribution to all holders of Preferred Stock (including any such distribution
made in connection with a consolidation or merger in which the Company is the
continuing or surviving corporation) of evidences of indebtedness, cash (other
than a regular quarterly cash dividend out of the earnings or retained earnings
of the Company), assets (other than a dividend payable in Preferred Stock, but
including any dividend payable in stock other than Preferred Stock) or
subscription rights or warrants (excluding those referred to in Section 11(b)
hereof), the Purchase Price to be in effect after such record date shall be
determined by multiplying the Purchase Price in effect immediately prior to such
record date by a fraction, the numerator of which shall be the Current Market
Price per share of Preferred Stock on such record date, less the fair market
value (as determined in good faith by the Board of Directors of the Company,
whose determination shall be described in a statement filed with the Rights
Agent and shall be binding on the Rights Agent) of the portion of the cash,
assets or evidences of indebtedness so to be distributed or of such subscription
rights or warrants applicable to a share of Preferred Stock and the denominator
of which shall be such Current Market Price per share of Preferred Stock. Such
adjustments shall be made successively whenever such a record date is fixed, and
in the event that such distribution is not so made, the Purchase Price shall be
adjusted to be the Purchase Price that would have been in effect if such record
date had not been fixed.

                  (d) (i) For the purpose of any computation hereunder, other
than computations made pursuant to Section 11(a)(iii) hereof, the "Current
Market Price" per share of Common Stock of a Person on any date shall be deemed
to be the average of the daily Closing Prices per share of such Common Stock for
the 30 consecutive Trading Days immediately prior to such date, and for purposes
of computations made pursuant to Section 11(a)(iii) hereof, the "Current Market
Price" per share of Common Stock on any date shall be deemed to be the average
of the daily Closing Prices per share of such Common Stock for the 10
consecutive Trading Days immediately following such date; provided, however,
that in the event that the

                                      -18-
<PAGE>
Current Market Price per share of Common Stock is determined during a period
following the announcement of (A) a dividend or distribution on such Common
Stock other than a regular quarterly cash dividend or the dividend of the Rights
or (B) any subdivision, combination or reclassification of such Common Stock,
and the ex-dividend date for such dividend or distribution, or the record date
for such subdivision, combination or reclassification, shall not have occurred
prior to the commencement of the requisite 30 Trading Day or 10 Trading Day
period, as set forth above, then, and in each such case, the Current Market
Price shall be properly adjusted to take into account ex-dividend trading. If
the Common Stock is not publicly held or not so listed or traded, "Current
Market Price" per share shall mean the fair value per share as determined in
good faith by the Board of Directors of the Company, whose determination shall
be described in a statement filed with the Rights Agent and shall be conclusive
for all purposes.

                  (ii) For the purpose of any computation hereunder, the
"Current Market Price" per share (or Fractional Share) of Preferred Stock shall
be determined in the same manner as set forth above for the Common Stock in
clause (i) of this Section 11(d) (other than the last sentence thereof). If the
Current Market Price per share (or Fractional Share) of Preferred Stock cannot
be determined in the manner provided above or if the Preferred Stock is not
publicly held or listed or traded in a manner described in clause (i) of this
Section 11(d), the "Current Market Price" per share of Preferred Stock shall be
conclusively deemed to be an amount equal to 100 (as such number may be
appropriately adjusted for such events as stock splits, stock dividends and
recapitalizations with respect to the Common Stock occurring after the date of
this Agreement) multiplied by the Current Market Price per share of the Common
Stock. If neither the Common Stock nor the Preferred Stock is publicly held or
so listed or traded, Current Market Price per share of the Preferred Stock shall
mean the fair value per share as determined in good faith by the Board of
Directors of the Company, whose determination shall be described in a statement
filed with the Rights Agent and shall be conclusive for all purposes. For all
purposes of this Agreement, the Current Market Price of a Fractional Share of
Preferred Stock shall be equal to the Current Market Price of one share of
Preferred Stock divided by 100.

                  (e) Anything herein to the contrary notwithstanding, no
adjustment in the Purchase Price shall be required unless such adjustment would
require an increase or decrease of at least 1% in the Purchase Price; provided,
however, that any adjustments that by reason of this Section 11(e) are not
required to be made shall be carried forward and taken into account in any
subsequent adjustment. All calculations under this Section 11 shall be made to
the nearest cent or to the nearest ten-thousandth of a share of Common Stock or
other share or to the nearest ten-thousandth of a Fractional Share of Preferred
Stock, as the case may be. Notwithstanding the first sentence of this Section
11(e), any adjustment required by this Section 11 shall be made no later than
the earlier of (i) three years from the date of the transaction which mandates
such adjustment or (ii) the Expiration Date.

                  (f) If as a result of an adjustment made pursuant to Section
11(a) or Section 13(a) hereof, the holder of any Right thereafter exercised
shall become entitled to receive in respect of such Right any shares of capital
stock other than Preferred Stock, thereafter the number of such other shares so
receivable upon exercise of any Right and the Purchase Price thereof shall be
subject to adjustment from time to time in a manner and on terms as nearly
equivalent as practicable to the provisions with respect to the Preferred Stock
contained in Sections 11(a), (b), (c), (e), (f), (g), (h), (i), (j), (k) and (m)
hereof, and the provisions of Sections

                                      -19-
<PAGE>
7, 9, 10, 13 and 14 hereof with respect to the Preferred Stock shall apply on
like terms to any such other shares.

                  (g) All Rights originally issued by the Company subsequent to
any adjustment made to the Purchase Price hereunder shall evidence the right to
purchase, at the adjusted Purchase Price, the number of Fractional Shares of
Preferred Stock purchasable from time to time hereunder upon exercise of the
Rights, all subject to further adjustment as provided herein.

                  (h) Unless the Company shall have exercised its election as
provided in Section 11(i) hereof, upon each adjustment of the Purchase Price as
a result of the calculations made in Sections 11(b) and (c) hereof, each Right
outstanding immediately prior to the making of such adjustment shall thereafter
evidence the right to purchase, at the adjusted Purchase Price, that number of
Fractional Shares of Preferred Stock (calculated to the nearest one
ten-thousandth of a Fractional Share) obtained by (i) multiplying (x) the number
of Fractional Shares of Preferred Stock covered by a Right immediately prior to
this adjustment by (y) the Purchase Price in effect immediately prior to such
adjustment of the Purchase Price, and (ii) dividing the product so obtained by
the Purchase Price in effect immediately after such adjustment of the Purchase
Price.

                  (i) The Company may elect, on or after the date of any
adjustment of the Purchase Price, to adjust the number of Rights in lieu of any
adjustment in the number of Fractional Shares of Preferred Stock purchasable
upon the exercise of a Right. Each of the Rights outstanding after the
adjustment in the number of Rights shall be exercisable for the number of
Fractional Shares of Preferred Stock for which a Right was exercisable
immediately prior to such adjustment. Each Right held of record prior to such
adjustment of the number of Rights shall become that number of Rights
(calculated to the nearest ten-thousandth) obtained by dividing the Purchase
Price in effect immediately prior to adjustment of the Purchase Price by the
Purchase Price in effect immediately after adjustment of the Purchase Price. The
Company shall make a public announcement of its election to adjust the number of
Rights, indicating the record date for the adjustment, and, if known at the
time, the amount of the adjustment to be made. This record date may be the date
on which the Purchase Price is adjusted or any day thereafter, but, if the
Rights Certificates have been issued, shall be at least 10 days later than the
date of the public announcement. If Rights Certificates have been issued, upon
each adjustment of the number of Rights pursuant to this Section 11(i), the
Company shall, as promptly as practicable, cause to be distributed to holders of
record of Rights Certificates on such record date Rights Certificates
evidencing, subject to Section 14 hereof, the additional Rights to which such
holders shall be entitled as a result of such adjustment, or, at the option of
the Company, shall cause to be distributed to such holders of record in
substitution and replacement for the Rights Certificates held by such holders
prior to the date of adjustment, and upon surrender thereof, if required by the
Company, new Rights Certificates evidencing all the Rights to which such holders
shall be entitled after such adjustment. Rights Certificates so to be
distributed shall be issued, executed and countersigned in the manner provided
for herein (and may bear, at the option of the Company, the adjusted Purchase
Price) and shall be registered in the names of the holders of record of Rights
Certificates on the record date specified in the public announcement.

                  (j) Irrespective of any adjustment or change in the Purchase
Price or the number of Fractional Shares of Preferred Stock issuable upon the
exercise of the Rights, the

                                      -20-
<PAGE>
Rights Certificates theretofore and thereafter issued may continue to express
the Purchase Price per Fractional Share and the number of Fractional Shares that
were expressed in the initial Rights Certificates issued hereunder.

                  (k) Before taking any action that would cause an adjustment
reducing the Purchase Price below the then par value, if any, or the stated
capital of the number of Fractional Shares of Preferred Stock or of the number
of shares of Common Stock or other securities issuable upon exercise of a Right,
the Company shall take any corporate action that may, in the opinion of its
counsel, be necessary in order that the Company may validly and legally issue
fully paid and nonassessable such number of Fractional Shares of Preferred Stock
or such number of shares of Common Stock or other securities at such adjusted
Purchase Price.

                  (l) In any case in which this Section 11 shall require that an
adjustment in the Purchase Price be made effective as of a record date for a
specified event, the Company may elect to defer until the occurrence of such
event the issuance to the holder of any Right exercised after such record date
the number of Fractional Shares of Preferred Stock and other capital stock or
securities of the Company, if any, issuable upon such exercise over and above
the number of Fractional Shares of Preferred Stock and other capital stock or
securities of the Company, if any, issuable upon such exercise on the basis of
the Purchase Price in effect prior to such adjustment; provided, however, that
the Company shall deliver to such holder a due bill or other appropriate
instrument evidencing such holder's right to receive such additional shares
(fractional or otherwise) or securities upon the occurrence of the event
requiring such adjustment.

                  (m) Anything in this Section 11 to the contrary
notwithstanding, the Company shall be entitled to make such reductions in the
Purchase Price, in addition to those adjustments expressly required by this
Section 11, as and to the extent that in their good faith judgment the Board of
Directors of the Company shall determine to be advisable in order that any (i)
consolidation or subdivision of the Preferred Stock, (ii) issuance wholly for
cash of any shares of Preferred Stock at less than the current market price,
(iii) issuance wholly for cash of shares of Preferred Stock or securities that
by their terms are convertible into or exchangeable for shares of Preferred
Stock, (iv) stock dividends or (v) issuance of rights, options or warrants
referred to in this Section 11 hereafter made by the Company to holders of its
Preferred Stock shall not be taxable to such stockholders.

                  (n) The Company covenants and agrees that it shall not, at any
time that there is an Acquiring Person, (i) consolidate with any other Person,
(ii) merge with or into any other Person or (iii) sell, lease or transfer (or
permit one or more Subsidiaries to sell, lease or transfer), in one transaction
or a series of related transactions, assets, earning power or cash flow
aggregating more than 50% of the assets, earning power or cash flow of the
Company and its Subsidiaries (taken as a whole) to any other Person or Persons,
if (x) at the time of or immediately after such consolidation, merger, sale,
lease or transfer there are any rights, warrants or other instruments or
securities of the Company or any other Person outstanding or agreements,
arrangements or understandings in effect that would substantially diminish or
otherwise eliminate the benefits intended to be afforded by the Rights, (y)
prior to, simultaneously with or immediately after such consolidation, merger,
sale, lease or transfer, the stockholders or other equity owners of the Person
who constitutes, or would constitute, the "Principal Party" for purposes of
Section 13(a) hereof shall have received a distribution of Rights

                                      -21-
<PAGE>
previously owned by such Person or any of its Affiliates or Associates, or (z)
the identity, form or nature of organization of the Principal Party (including,
without limitation, the selection of the Person that will be the Principal Party
as a result of the Company's entering into one or more consolidations, mergers,
sales, leases or transfers with more than one party) would preclude or limit the
exercise of Rights or otherwise diminish substantially or eliminate the benefits
intended to be afforded by the Rights.

                  (o) The Company covenants and agrees that, after the
Distribution Date, it will not, except as permitted by Section 23, Section 24 or
Section 27 hereof, take (or permit any Subsidiary to take) any action if the
purpose of such action is to, or if at the time such action is taken it is
reasonably foreseeable that such action will, diminish substantially or
eliminate the benefits intended to be afforded by the Rights.

                  (p) Notwithstanding Section 3(c) hereof or any other provision
of this Agreement to the contrary, in the event that the Company shall at any
time after the Rights Dividend Declaration Date and prior to the Distribution
Date (i) declare a dividend on the outstanding shares of Common Stock payable in
shares of Common Stock, (ii) subdivide the outstanding shares of Common Stock,
(iii) combine the outstanding shares of Common Stock into a smaller number of
shares or (iv) otherwise reclassify the outstanding shares of Common Stock
(including any such reclassification in connection with a consolidation or
merger in which the Company is the continuing or surviving corporation), the
number of Rights associated with each share of Common Stock then outstanding, or
issued or delivered thereafter with Rights, shall be proportionately adjusted so
that the number of Rights thereafter associated with each share of Common Stock
following any such event shall equal the result obtained by multiplying the
number of Rights associated with each share of Common Stock immediately prior to
such event by a fraction (the "Adjustment Fraction"), the numerator of which
shall be the total number of shares of Common Stock outstanding immediately
prior to the occurrence of the event and the denominator of which shall be the
total number of shares of Common Stock outstanding immediately following the
occurrence of such event. In lieu of such adjustment in the number of Rights
associated with one share of Common Stock, the Company may elect to adjust the
number of Fractional Shares of Preferred Stock purchasable upon the exercise of
one Right and the Purchase Price. If the Company makes such election, the number
of Rights associated with one share of Common Stock shall remain unchanged, and
the number of Fractional Shares of Preferred Stock purchasable upon exercise of
one Right and the Purchase Price shall be proportionately adjusted so that (i)
the number of Fractional Shares of Preferred Stock purchasable upon exercise of
a Right following such adjustment shall equal the product of the number of
Fractional Shares of Preferred Stock purchasable upon exercise of a Right
immediately prior to such adjustment multiplied by the Adjustment Fraction and
(ii) the Purchase Price following such adjustment shall equal the product of the
Purchase Price immediately prior to such adjustment multiplied by the Adjustment
Fraction.

                  Section 12. Certificate of Adjusted Purchase Price or Number
of Shares. Whenever an adjustment is made as provided in Section 11 or Section
13 hereof, the Company shall (a) promptly prepare a certificate setting forth
such adjustment and a brief statement of the facts accounting for such
adjustment, (b) promptly file with the Rights Agent, and with each transfer
agent for the Preferred Stock and the Common Stock, a copy of such certificate
and (c) mail a brief summary thereof to each registered holder of a Rights
Certificate (or, if prior to the

                                      -22-
<PAGE>
Distribution Date, to each registered holder of a certificate representing
shares of Common Stock) in accordance with Section 26 hereof. The Rights Agent
shall be fully protected in relying on any such certificate and on any
adjustment therein contained.

                  Section 13. Consolidation, Merger or Sale or Transfer of
Assets, Cash Flow or Earning Power.

                  (a) In the event that, from and after the time an Acquiring
Person has become such, directly or indirectly, (x) the Company shall
consolidate with, or merge with and into, any other Person, and the Company
shall not be the continuing or surviving corporation of such consolidation or
merger, (y) any Person shall consolidate with, or merge with or into, the
Company, and the Company shall be the continuing or surviving corporation of
such consolidation or merger, and, in connection with such consolidation or
merger, all or part of the outstanding shares of Common Stock shall be changed
into or exchanged for stock or other securities of the Company or any other
Person or cash or any other property, or (z) the Company shall sell, lease or
otherwise transfer (or one or more of its Subsidiaries shall sell, lease or
otherwise transfer), in one transaction or a series of related transactions,
assets, cash flow or earning power aggregating more than 50% of the assets, cash
flow or earning power of the Company and its Subsidiaries (taken as a whole) to
any Person or Persons (other than the Company or any wholly owned Subsidiary of
the Company or any combination thereof in one or more transactions each of which
complies (and all of which together comply) with Section 11(o) hereof), then,
and in each such case (except as may be contemplated by Section 13(d) hereof),
proper provision shall be made so that: (i) the Purchase Price shall be adjusted
to be the Purchase Price immediately prior to the first occurrence of a
Triggering Event multiplied by the number of Fractional Shares of Preferred
Stock for which a Right was exercisable immediately prior to such first
occurrence; (ii) on and after the Distribution Date, each holder of a Right,
except as provided in Section 7(e) hereof, shall thereafter have the right to
receive, upon the exercise thereof at the Purchase Price in accordance with the
terms of this Agreement, in lieu of shares of Preferred Stock or Common Stock of
the Company, such number of validly authorized and issued, fully paid,
nonassessable and freely tradeable shares of Common Stock of the Principal Party
(as such term is hereinafter defined), not subject to any liens, encumbrances,
rights of first refusal or other adverse claims, as shall be equal to the result
obtained by dividing the Purchase Price by 50% of the Current Market Price per
share of the Common Stock of such Principal Party on the date of consummation of
such Flip-Over Event; provided that the Purchase Price and the number of shares
of Common Stock of such Principal Party issuable upon exercise of each Right
shall be further adjusted as provided in this Agreement to reflect any events
occurring after the date of such first occurrence of a Triggering Event or after
the date of such Flip-Over Event, as applicable; (iii) such Principal Party
shall thereafter be liable for, and shall assume, by virtue of such Flip-Over
Event, all the obligations and duties of the Company pursuant to this Agreement;
(iv) the term "Company" shall thereafter be deemed to refer to such Principal
Party, it being specifically intended that the provisions of Section 11 hereof
shall apply only to such Principal Party following the first occurrence of a
Flip-Over Event; (v) such Principal Party shall take such steps (including, but
not limited to, the reservation of a sufficient number of shares of its Common
Stock) in connection with the consummation of any such transaction as may be
necessary to assure that the provisions hereof shall thereafter be applicable,
as nearly as reasonably may be, in relation to its shares of Common Stock
thereafter deliverable upon the

                                      -23-
<PAGE>
exercise of the Rights; and (vi) the provisions of Section 11(a)(ii) hereof
shall be of no effect following the occurrence of any Flip-Over Event.

                  (b) "Principal Party" shall mean

                  (i) in the case of any transaction described in clause (x) or
         (y) of the first sentence of Section 13(a), (A) the Person that is the
         issuer of any securities into which shares of Common Stock of the
         Company are converted in such merger or consolidation, or, if there is
         more than one such issuer, the issuer the Common Stock of which has the
         greatest aggregate market value, or (B) if no securities are so issued,
         (x) the Person that survives such consolidation or is the other party
         to the merger and survives such merger, or, if there is more than one
         such Person, the Person the Common Stock of which has the greatest
         aggregate market value or (y) if the Person that is the other party to
         the merger does not survive the merger, the Person that does survive
         the merger (including the Company if it survives); and

                  (ii) in the case of any transaction described in clause (z) of
         the first sentence of Section 13(a), the Person that is the party
         receiving the greatest portion of the assets or earning power
         transferred pursuant to such transaction or transactions, or, if each
         Person that is a party to such transaction or transactions receives the
         same portion of the assets or earning power so transferred, or if the
         Person receiving the greatest portion of the assets or earning power
         cannot be determined, the Person the Common Stock of which has the
         greatest aggregate market value;

provided, however, that in any such case, if the Common Stock of such Person is
not at such time and has not been continuously over the preceding twelve-month
period registered under Section 12 of the Exchange Act, and if (1) such Person
is a direct or indirect Subsidiary of another Person the Common Stock of which
is and has been so registered, "Principal Party" shall refer to such other
Person; (2) such Person is a Subsidiary, directly or indirectly, of more than
one Person, the Common Stocks of all of which are and have been so registered,
"Principal Party" shall refer to whichever of such Persons is the issuer of the
Common Stock having the greatest aggregate market value; and (3) such Person is
owned, directly or indirectly, by a joint venture formed by two or more Persons
that are not owned, directly or indirectly, by the same Person, the rules set
forth in (1) and (2) above shall apply to each of the chains of ownership having
an interest in such joint venture as if such party were a "Subsidiary" of both
or all of such joint venturers and the Principal Parties in each such chain
shall bear the obligations set forth in this Section 13 in the same ratio as
their direct or indirect interests in such Person bear to the total of such
interests.

                  (c) The Company shall not consummate any Flip-Over Event
unless each Principal Party (or Person that may become a Principal Party as a
result of such Flip-Over Event) shall have a sufficient number of authorized
shares of its Common Stock that have not been issued or reserved for issuance to
permit the exercise in full of the Rights in accordance with this Section 13 and
unless prior thereto the Company and each such Principal Party shall have
executed and delivered to the Rights Agent a supplemental agreement providing
for the terms set forth in paragraphs (a) and (b) of this Section 13 and further
providing that, as soon as practicable after the date of such Flip-Over Event,
the Principal Party at its own expense will

                                      -24-
<PAGE>
                  (i) prepare and file a registration statement under the
         Securities Act with respect to the Rights and the securities
         purchasable upon exercise of the Rights on an appropriate form, and
         will use its best efforts to cause such registration statement to (A)
         become effective as soon as practicable after such filing and (B)
         remain effective (with a prospectus at all times meeting the
         requirements of the Securities Act) until the Expiration Date;

                  (ii) use its best efforts to qualify or register the Rights
         and the securities purchasable upon exercise of the Rights under the
         "blue sky" laws of such jurisdictions as may be necessary or
         appropriate;

                  (iii) use its best efforts, if the Common Stock of the
         Principal Party is or shall become listed on a national securities
         exchange, to list (or continue the listing of) the Rights and the
         securities purchasable upon exercise of the Rights on such securities
         exchange and, if the Common Stock of the Principal Party shall not be
         listed on a national securities exchange, to cause the Rights and the
         securities purchasable upon exercise of the Rights to be reported by
         NASDAQ or such other transaction reporting system then in use; and

                  (iv) deliver to holders of the Rights historical financial
         statements for the Principal Party and each of its Affiliates that
         comply in all respects with the requirements for registration on Form
         10 under the Exchange Act.

The provisions of this Section 13 shall similarly apply to successive mergers or
consolidations or sales or other transfers. In the event that a Flip-Over Event
shall occur at any time after the occurrence of a Flip-In Event, the Rights that
have not theretofore been exercised shall thereafter become exercisable in the
manner described in Section 13(a).

                  (d) Notwithstanding anything in this Agreement to the
contrary, Section 13 shall not be applicable to a transaction described in
subparagraphs (x) and (y) of Section 13(a) if (i) such transaction is
consummated with a Person or Persons who acquired shares of Common Stock
pursuant to a Permitted Offer (or a wholly owned subsidiary of any such Person
or Persons), (ii) the price per share of Common Stock offered in such
transaction is not less than the price per share of Common Stock paid to all
holders of Common Stock whose shares were purchased pursuant to such Permitted
Offer, and (iii) the form of consideration being offered to the remaining
holders of shares of Common Stock pursuant to such transaction is the same as
the form of consideration paid pursuant to such Permitted Offer. Upon
consummation of any such transaction contemplated by this Section 13(d), all
Rights hereunder shall expire.

                  Section 14. Fractional Rights and Fractional Shares.

                  (a) The Company shall not be required to issue fractions of
Rights, except prior to the Distribution Date as provided in Section 11(p)
hereof, or to distribute Rights Certificates or scrip evidencing fractional
Rights. In lieu of such fractional Rights, there shall be paid to the registered
holders of the Rights Certificates with regard to which such fractional Rights
would otherwise be issuable, an amount in cash equal to the same fraction of the
Closing

                                      -25-
<PAGE>
Price of one Right for the Trading Day immediately prior to the date on which
such fractional Rights would have been otherwise issuable.

                  (b) The Company shall not be required to issue fractions of
shares of Preferred Stock (other than, except as provided in Section 7(c)
hereof, fractions that are integral multiples of a Fractional Share of Preferred
Stock) upon exercise of the Rights or to distribute certificates or scrip
evidencing fractional shares of Preferred Stock (other than, except as provided
in Section 7(c) hereof, fractions that are integral multiples of a Fractional
Share of Preferred Stock). Interests in fractions of shares of Preferred Stock
in integral multiples of a Fractional Share of Preferred Stock may, at the
election of the Company in its sole discretion, be evidenced by depositary
receipts, pursuant to an appropriate agreement between the Company and a
depositary selected by it, provided that such agreement shall provide that the
holders of such depositary receipts shall have all the rights, privileges and
preferences to which they are entitled as beneficial owners of the shares of
Preferred Stock represented by such depositary receipts. In lieu of fractional
shares of Preferred Stock that are not integral multiples of a Fractional Share
of Preferred Stock, the Company may pay to the registered holders of Rights
Certificates at the time such Rights are exercised as herein provided an amount
in cash equal to the same fraction of one one-hundredth of the Closing Price of
a share of Preferred Stock for the Trading Day immediately prior to the date of
such exercise.

                  (c) Following the occurrence of a Triggering Event, the
Company shall not be required to issue fractions of shares of Common Stock upon
exercise of the Rights or to distribute certificates or scrip evidencing
fractional shares of Common Stock. In lieu of fractional shares of Common Stock,
the Company may pay to the registered holders of Rights Certificates at the time
such Rights are exercised as herein provided an amount in cash equal to the same
fraction of the Closing Price of one share of Common Stock for the Trading Day
immediately prior to the date of such exercise.

                  (d) The holder of a Right by the acceptance of the Right
expressly waives his right to receive any fractional Rights or any fractional
shares upon exercise of a Right, except as permitted by this Section 14.

                  Section 15. Rights of Action. All rights of action in respect
of this Agreement, other than rights of action vested in the Rights Agent
pursuant to Section 18 hereof, are vested in the respective registered holders
of the Rights Certificates (and, prior to the Distribution Date, the registered
holders of the Common Stock) and, where applicable, the Company; and any
registered holder of any Rights Certificate (or, prior to the Distribution Date,
of the Common Stock), without the consent of the Rights Agent or of the holder
of any other Rights Certificate (or, prior to the Distribution Date, of the
Common Stock), may, in his own behalf and for his own benefit, enforce, and may
institute and maintain any suit, action or proceeding against the Company to
enforce, or otherwise act in respect of, his right to exercise the Rights
evidenced by such Rights Certificate in the manner provided in such Rights
Certificate and in this Agreement. Without limiting the foregoing or any
remedies available to the holders of Rights, it is specifically acknowledged
that the holders of Rights would not have an adequate remedy at law for any
breach of this Agreement and shall be entitled to specific performance of the
obligations hereunder and injunctive relief against actual or threatened
violations of the obligations hereunder of any Person subject to this Agreement.
After a Triggering Event, holders of Rights

                                      -26-
<PAGE>
shall be entitled to recover the reasonable costs and expenses, including
attorneys' fees, incurred by them in any action to enforce the provisions of
this Agreement.

                  Section 16. Agreement of Rights Holders. Every holder of a
Right by accepting the same consents and agrees with the Company and the Rights
Agent and with every other holder of a Right that:

                  (a) prior to the Distribution Date, the Rights will not be
evidenced by Rights Certificates and will be transferable only in connection
with the transfer of Common Stock;

                  (b) after the Distribution Date, the Rights Certificates will
be transferable only on the registry books of the Rights Agent if surrendered at
the principal office or offices of the Rights Agent designated for such
purposes, duly endorsed or accompanied by a proper instrument of transfer and
with the form of assignment set forth on the reverse side thereof and the
certificate contained therein duly completed and fully executed;

                  (c) subject to Section 6(a) and Section 7(f) hereof, the
Company and the Rights Agent may deem and treat the Person in whose name a
Rights Certificate (or, prior to the Distribution Date, the associated Common
Stock certificate) is registered as the absolute owner thereof and of the Rights
evidenced thereby (notwithstanding any notations of ownership or writing on the
Rights Certificates or the associated Common Stock certificate made by anyone
other than the Company or the Rights Agent) for all purposes whatsoever, and
neither the Company nor the Rights Agent shall be affected by any notice to the
contrary; and

                  (d) notwithstanding anything in this Agreement to the
contrary, neither the Company nor the Rights Agent shall have any liability to
any holder of a Right or other Person as a result of its inability to perform
any of its obligations under this Agreement by reason of any preliminary or
permanent injunction or other order, decree or ruling issued by a court of
competent jurisdiction or by a governmental, regulatory or administrative agency
or commission, or any statute, rule, regulation or executive order promulgated
or enacted by any governmental authority, prohibiting or otherwise restraining
performance of such obligation; provided, however, the Company must use its best
efforts to have any such order, decree or ruling lifted or otherwise overturned
as soon as possible.

                  Section 17. Rights Certificate Holder Not Deemed a
Stockholder. No holder, as such, of any Rights Certificate shall be entitled to
vote, receive dividends or be deemed for any purpose the holder of the number of
Fractional Shares of Preferred Stock or any other securities of the Company that
may at any time be issuable upon the exercise of the Rights represented thereby,
nor shall anything contained herein or in any Rights Certificate be construed to
confer upon the holder of any Rights Certificate, as such, any of the rights of
a stockholder of the Company or any right to vote for the election of directors
or upon any matter submitted to stockholders at any meeting thereof, or to give
or withhold consent to any corporate action, or to receive notice of meetings or
other actions affecting stockholders (except as provided in Section 25 hereof),
or to receive dividends or subscription rights, or otherwise, until the Right or
Rights evidenced by such Rights Certificate shall have been exercised in
accordance with the provisions hereof.

                  Section 18. Concerning the Rights Agent.

                  (a) The Company agrees to pay to the Rights Agent reasonable
compensation for all services rendered by it hereunder and, from time to time,
on demand of the Rights Agent, its reasonable expenses and counsel fees and
disbursements and other reasonable disbursements incurred in the administration
and execution of this Agreement and the exercise and performance of its duties
hereunder. The Company also agrees to indemnify the Rights Agent for, and to
hold it harmless against, any loss, liability or expense, incurred without gross
negligence, bad faith or willful misconduct on the part of the Rights Agent, for
anything done or omitted by the Rights Agent in connection with the acceptance
and administration of this Agreement, including the costs and expenses of
defending against any claim of liability in the premises.

                  (b) The Rights Agent shall be protected and shall incur no
liability for or in respect of any action taken, suffered or omitted by it in
connection with its administration of this Agreement in reliance upon any Rights
Certificate or certificate for Common Stock or for other securities of the
Company, instrument of assignment or transfer, power of attorney, endorsement,
affidavit, letter, notice, direction, consent, certificate, statement or other
paper or document believed by it, after proper inquiry or examination, to be
genuine and to be signed, executed and, where necessary, guaranteed, verified or
acknowledged, by the proper Person or Persons.

                  Section 19. Merger or Consolidation or Change of Name of
Rights Agent.

                  (a) Any corporation into which the Rights Agent or any
successor Rights Agent may be merged or with which it may be consolidated, or
any corporation resulting from any merger or consolidation to which the Rights
Agent or any successor Rights Agent shall be a party, or any corporation
succeeding to the corporate trust or stock transfer business of the Rights Agent
or any successor Rights Agent, shall be the successor to the Rights Agent under
this Agreement without the execution or filing of any paper or any further act
on the part of any of the parties hereto; provided, however, that such
corporation would be eligible for appointment as a successor Rights Agent under
the provisions of Section 21 hereof. In case at the time such successor Rights
Agent shall succeed to the agency created by this Agreement, any of the Rights
Certificates shall have been countersigned but not delivered, any such successor
Rights Agent may adopt the countersignature of a predecessor Rights Agent and
deliver such Rights Certificates so countersigned; and in case at that time any
of the Rights Certificates shall not have been countersigned, any successor
Rights Agent may countersign such Rights Certificates either in the name of the
predecessor or in the name of the successor Rights Agent; and in all such cases
such Rights Certificates shall have the full force provided in the Rights
Certificates and in this Agreement.

                  (b) In case at any time the name of the Rights Agent shall be
changed and at such time any of the Rights Certificates shall have been
countersigned but not delivered, the Rights Agent may adopt the countersignature
under its prior name and deliver Rights Certificates so countersigned; and in
case at that time any of the Rights Certificates shall not have been
countersigned, the Rights Agent may countersign such Rights Certificates either
in its prior name or in its changed name; and in all such cases such Rights
Certificates shall have the full force provided in the Rights Certificates and
in this Agreement.

                  Section 20. Duties of Rights Agent. The Rights Agent
undertakes the duties and obligations imposed by this Agreement upon the
following terms and conditions, by all of which the Company and the holders of
Rights Certificates, by their acceptance thereof, shall be bound:

                  (a) The Rights Agent may consult with legal counsel (who may
be legal counsel for the Company), and the opinion of such counsel shall be full
and complete authorization and protection to the Rights Agent as to any action
taken or omitted by it in good faith and in accordance with such opinion.

                  (b) Whenever in the performance of its duties under this
Agreement the Rights Agent shall deem it necessary or desirable that any fact or
matter (including, without limitation, the identity of any Acquiring Person and
the determination of "Current Market Price") be proved or established by the
Company prior to taking or suffering any action hereunder, such fact or matter
(unless other evidence in respect thereof be herein specifically prescribed) may
be deemed to be conclusively proved and established by a certificate signed by
the Chairman of the Board, the President, any Vice President, the Treasurer, any
Assistant Treasurer, the Secretary or any Assistant Secretary of the Company and
delivered to the Rights Agent; and such certificate shall be full authorization
to the Rights Agent for any action taken or suffered in good faith by it under
the provisions of this Agreement in reliance upon such certificate.

                  (c) The Rights Agent shall be liable hereunder only for its
own gross negligence, bad faith or willful misconduct. In no event shall the
Rights Agent be liable for special, indirect or consequential loss or damage of
any kind whatsoever (including but not limited to lost profits), even if the
Rights Agent has been advised of the likelihood of such loss or damage and
regardless of the form of action.

                  (d) The Rights Agent shall not be liable for or by reason of
any of the statements of fact or recitals contained in this Agreement or in the
Rights Certificates or be required to verify the same (except as to its
countersignature on such Rights Certificates), but all such statements and
recitals are and shall be deemed to have been made by the Company only.

                  (e) The Rights Agent shall not be under any responsibility in
respect of the validity of this Agreement or the execution and delivery hereof
(except the due execution hereof by the Rights Agent) or in respect of the
validity or execution of any Rights Certificate (except its countersignature
thereof); nor shall it be responsible for any breach by the Company of any
covenant or condition contained in this Agreement or in any Rights Certificate;
nor shall it be responsible for any adjustment required under the provisions of
Section 11 or Section 13 hereof or responsible for the manner, method or amount
of any such adjustment or the ascertaining of the existence of facts that would
require any such adjustment (except with respect to the exercise of Rights
evidenced by Rights Certificates after receipt of actual knowledge of any such
adjustment); nor shall it by any act hereunder be deemed to make any
representation or warranty as to the authorization or reservation of any shares
of Preferred Stock or Common Stock or other securities to be issued pursuant to
this Agreement or any Rights Certificate or as to whether any shares of
Preferred Stock or Common Stock or other securities will, when so issued, be
validly authorized and issued, fully paid and nonassessable.

                                      -29-
<PAGE>
                  (f) The Company agrees that it will perform, execute,
acknowledge and deliver or cause to be performed, executed, acknowledged and
delivered all such further and other acts, instruments and assurances as may
reasonably be required by the Rights Agent for the carrying out or performing by
the Rights Agent of the provisions of this Agreement.

                  (g) The Rights Agent is hereby authorized and directed to
accept instructions with respect to the performance of its duties hereunder from
the Chairman of the Board, the President, any Vice President, the Secretary, any
Assistant Secretary, the Treasurer or any Assistant Treasurer of the Company,
and to apply to such officers for advice or instructions in connection with its
duties, and it shall not be liable for any action taken or suffered to be taken
by it in good faith in accordance with instructions of any such officer.

                  (h) The Rights Agent and any stockholder, director, officer or
employee of the Rights Agent may buy, sell or deal in any of the Rights or other
securities of the Company or become pecuniarily interested in any transaction in
which the Company may be interested, or contract with or lend money to the
Company or otherwise act as fully and freely as though it were not Rights Agent
under this Agreement. Nothing herein shall preclude the Rights Agent from acting
in any other capacity for the Company or for any other legal entity.

                  (i) The Rights Agent may execute and exercise any of the
rights or powers hereby vested in it or perform any duty hereunder either itself
or by or through its attorneys or agents, and the Rights Agent shall not be
answerable or accountable for any act, omission, default, neglect or misconduct
of any such attorneys or agents or for any loss to the Company resulting from
any such act, omission, default, neglect or misconduct; provided, however, that
reasonable care was exercised in the selection and continued employment thereof.

                  (j) No provision of this Agreement shall require the Rights
Agent to expend or risk its own funds or otherwise incur any financial liability
in the performance of any of its duties hereunder or in the exercise of its
rights if there shall be reasonable grounds for believing that repayment of such
funds or adequate indemnification against such risk or liability is not
reasonably assured to it.

                  (k) If, with respect to any Rights Certificate surrendered to
the Rights Agent for exercise or transfer, the certificate attached to the form
of assignment or form of election to purchase, as the case may be, has either
not been completed or indicates an affirmative response to clause 1 and/or 2
thereof, the Rights Agent shall not take any further action with respect to such
requested exercise or transfer without first consulting with the Company.

                  Section 21. Change of Rights Agent. The Rights Agent or any
successor Rights Agent may resign and be discharged from its duties under this
Agreement upon 30 days' notice in writing mailed to the Company, and to each
transfer agent of the Common Stock and the Preferred Stock, by registered or
certified mail, and to the registered holders, if any, of the Rights
Certificates by first-class mail. The Company may remove the Rights Agent or any
successor Rights Agent (with or without cause) upon 30 days' notice in writing,
mailed to the Rights Agent or successor Rights Agent, as the case may be, and to
each transfer agent of the Common Stock and the Preferred Stock, by registered
or certified mail, and to the registered holders of the Rights Certificates, if
any, by first-class mail. If the Rights Agent shall resign or

                                      -30-
<PAGE>
be removed or shall otherwise become incapable of acting, the Company shall
appoint a successor to the Rights Agent. Notwithstanding the foregoing
provisions of this Section 21, in no event shall the resignation or removal of a
Rights Agent be effective until a successor Rights Agent shall have been
appointed and have accepted such appointment. If the Company shall fail to make
such appointment within a period of 30 days after giving notice of such removal
or after it has been notified in writing of such resignation or incapacity by
the resigning or incapacitated Rights Agent or by the registered holder of a
Rights Certificate (who shall, with such notice, submit his Rights Certificate
for inspection by the Company), then the Rights Agent or the registered holder
of any Rights Certificate may apply to any court of competent jurisdiction for
the appointment of a new Rights Agent. Any successor Rights Agent, whether
appointed by the Company or by such a court, shall be (a) a corporation or trust
company organized and doing business under the laws of the United States or of
the State of New York (or of any other state of the United States so long as
such corporation or trust company is authorized to conduct a stock transfer or
corporate trust business in the State of New York), in good standing, which is
authorized under such laws to exercise corporate trust or stock transfer powers
and is subject to supervision or examination by federal or state authority and
which has at the time of its appointment as Rights Agent a combined capital and
surplus of at least $50,000,000 or (b) an affiliate of a corporation or trust
company described in clause (a) of this sentence. After appointment, the
successor Rights Agent shall be vested with the same powers, rights, duties and
responsibilities as if it had been originally named as Rights Agent without
further act or deed; but the predecessor Rights Agent shall deliver and transfer
to the successor Rights Agent any property at the time held by it hereunder, and
execute and deliver any further assurance, conveyance, act or deed necessary for
the purpose. Not later than the effective date of any such appointment, the
Company shall file notice thereof in writing with the predecessor Rights Agent
and each transfer agent of the Common Stock and the Preferred Stock, and mail a
notice thereof in writing to the registered holders, if any, of the Rights
Certificates. Failure to give any notice provided for in this Section 21,
however, or any defect therein, shall not affect the legality or validity of the
resignation or removal of the Rights Agent or the appointment of the successor
Rights Agent, as the case may be.

                  Section 22. Issuance of New Rights Certificates.
Notwithstanding any of the provisions of this Agreement or of the Rights to the
contrary, the Company may, at its option, issue new Rights Certificates
evidencing Rights in such form as may be approved by its Board of Directors to
reflect any adjustment or change in the Purchase Price and the number or kind or
class of shares or other securities or property purchasable under the Rights
Certificates made in accordance with the provisions of this Agreement. In
addition, in connection with the issuance or sale of shares of Common Stock
following the Distribution Date and prior to the Expiration Date, the Company
(a) shall, with respect to shares of Common Stock so issued or sold pursuant to
the exercise of stock options or under any employee plan or arrangement granted
or awarded on or prior to the Distribution Date, or upon the exercise,
conversion or exchange of securities issued by the Company on or prior to the
Distribution Date, and (b) may, in any other case, if deemed necessary or
appropriate by the Board of Directors of the Company, issue Rights Certificates
representing the appropriate number of Rights in connection with such issuance
or sale; provided, however, that (i) no such Rights Certificate shall be issued
if, and to the extent that, the Company shall be advised by counsel that such
issuance would create a significant risk of material adverse tax consequences to
the Company or the Person to whom such Rights Certificate would be issued, and
(ii) no such Rights Certificate shall be issued if, and to the

                                      -31-
<PAGE>
extent that, appropriate adjustment shall otherwise have been made in lieu of
the issuance thereof.

                  Section 23. Redemption and Termination.

                  (a) The Board of Directors of the Company may, at its option,
at any time prior to the earlier of (i) the close of business on the tenth day
following the first date of public announcement of the occurrence of a Flip-In
Event (or, if such date shall have occurred prior to the Record Date, the close
of business on the tenth day following the Record Date) and (ii) the Expiration
Date, cause the Company to redeem all but not less than all the then outstanding
Rights at a redemption price of $.01 per Right, as such amount may be
appropriately adjusted, if necessary, to reflect any stock split, stock dividend
or similar transaction occurring after the Rights Dividend Declaration Date
(such redemption price being hereinafter referred to as the "Redemption Price");
provided, however, that the Rights may not be redeemed following any merger to
which the Company is a party that (i) occurs when there is an Acquiring Person
and (ii) was not approved (x) prior to the time such Person became an Acquiring
Person by the Board of Directors of the Company and (y) prior to such merger by
the stockholders of the Company at a stockholders' meeting (and not by written
consent). Notwithstanding anything contained in this Agreement to the contrary,
the Rights shall not be exercisable after the first occurrence of a Flip-In
Event until such time as the Company's right of redemption hereunder has
expired. The Company may, at its option, pay the Redemption Price in cash,
shares of Common Stock (based on the Current Market Price of the Common Stock at
the time of redemption) or any other form of consideration deemed appropriate by
the Board of Directors.

                  (b) Immediately upon the effectiveness of the action of the
Board of Directors of the Company ordering the redemption of the Rights (the
effectiveness of which action may be conditioned on the occurrence of one or
more events or on the existence of one or more facts or may be effective at some
future time), evidence of which shall be filed with the Rights Agent and without
any further action and without any notice, the right to exercise the Rights will
terminate and the only right thereafter of the holders of Rights shall be to
receive the Redemption Price for each Right so held. Promptly after the
effectiveness of the action of the Board of Directors ordering the redemption of
the Rights, the Company shall give notice of such redemption to the Rights Agent
and the registered holders of the then outstanding Rights by mailing such notice
to all such holders at each holder's last address as it appears upon the
registry books of the Rights Agent or, prior to the Distribution Date, on the
registry books of the Company for the Common Stock. Any notice that is mailed in
the manner herein provided shall be deemed given, whether or not the holder
receives the notice. Each such notice of redemption shall state the method by
which the payment of the Redemption Price will be made.

                  Section 24. Exchange.

                  (a) The Board of Directors of the Company may, at its option,
at any time and from time to time after the occurrence of a Flip-In Event,
exchange all or part of the then outstanding and exercisable Rights (which shall
not include Rights that have become void pursuant to the provisions of Section
7(e) hereof) for shares of Common Stock or Common Stock Equivalents or any
combination thereof, at an exchange ratio of one share of Common Stock, or such
number of Common Stock Equivalents or units representing fractions thereof as

                                      -32-
<PAGE>
would be deemed to have the same value as one share of Common Stock, per Right,
appropriately adjusted, if necessary, to reflect any stock split, stock dividend
or similar transaction occurring after the Rights Dividend Declaration Date
(such exchange ratio being hereinafter referred to as the "Exchange Ratio").
Notwithstanding the foregoing, the Board of Directors may not effect such
exchange at any time after (i) any Person (other than an Exempt Person),
together with all Affiliates and Associates of such Person, becomes the
Beneficial Owner of 50% or more of the shares of Common Stock then outstanding
or (ii) the occurrence of a Flip-Over Event.

                  (b) Immediately upon the effectiveness of the action of the
Board of Directors of the Company ordering the exchange of any Rights pursuant
to and in accordance with subsection (a) of this Section 24 (the effectiveness
of which action may be conditioned on the occurrence of one or more events or on
the existence of one or more facts or may be effective at some future time) and
without any further action and without any notice, the right to exercise such
Rights shall terminate and the only right thereafter of a holder of such Rights
shall be to receive that number of shares of Common Stock and/or Common Stock
Equivalents equal to the number of such Rights held by such holder multiplied by
the Exchange Ratio. The Company shall promptly give public notice of any such
exchange; provided, however, that the failure to give, or any defect in, such
notice shall not affect the validity of such exchange. The Company promptly
shall mail a notice of any such exchange to all of the registered holders of
such Rights at their last addresses as they appear upon the registry books of
the Rights Agent. Any notice which is mailed in the manner herein provided shall
be deemed given, whether or not the holder receives the notice. Each such notice
of exchange will state the method by which the exchange of the shares of Common
Stock and/or Common Stock Equivalents for Rights will be effected and, in the
event of any partial exchange, the number of Rights that will be exchanged. Any
partial exchange shall be effected as nearly pro rata as possible based on the
number of Rights (other than Rights that have become void pursuant to the
provisions of Section 7(e) hereof) held by each holder of Rights.

                  (c) In the event that the number of shares of Common Stock
that are authorized by the Company's certificate of incorporation but not
outstanding or reserved for issuance for purposes other than upon exercise of
the Rights is not sufficient to permit an exchange of Rights as contemplated in
accordance with this Section 24, the Company may, at its option, take all such
action as may be necessary to authorize additional shares of Common Stock for
issuance upon exchange of the Rights.

                  (d) The Company shall not be required to issue fractions of
shares of Common Stock or to distribute certificates or scrip evidencing
fractional shares of Common Stock upon exchange of the Rights. In lieu of such
fractional shares of Common Stock, the Company shall pay to the registered
holders of Rights with regard to which such fractional shares of Common Stock
would otherwise be issuable an amount in cash equal to the same fraction of the
value of a whole share of Common Stock. For purposes of this Section 24, the
value of a whole share of Common Stock shall be the Closing Price per share of
Common Stock for the Trading Day immediately prior to the date of exchange
pursuant to this Section 24, and the value of any Common Stock Equivalent shall
be deemed to have the same value as the Common Stock on such date.

                  Section 25. Notice of Certain Events.

                  (a) In case the Company shall propose, at any time after the
Distribution Date, (i) to pay any dividend payable in stock of any class to the
holders of Preferred Stock or to make any other distribution to the holders of
Preferred Stock (other than a regular quarterly cash dividend out of earnings or
retained earnings of the Company), or (ii) to offer to the holders of Preferred
Stock rights or warrants to subscribe for or to purchase any additional shares
of Preferred Stock or shares of stock of any class or any other securities,
rights or options, or (iii) to effect any reclassification of its Preferred
Stock (other than a reclassification involving only the subdivision of
outstanding shares of Preferred Stock), or (iv) to effect any consolidation or
merger into or with any other Person (other than a wholly owned Subsidiary of
the Company in a transaction that complies with Section 11(o) hereof), or to
effect any sale, lease or other transfer of all or substantially all the
Company's assets, cash flow or earning power to any other Person or Persons
(other than a wholly owned Subsidiary of the Company in a transaction that
complies with Section 11(o) hereof), or (v) to effect the liquidation,
dissolution or winding up of the Company, then, in each such case, the Company
shall give to each holder of record of a Rights Certificate, to the extent
feasible and in accordance with Section 26 hereof, a notice of such proposed
action, which shall specify the record date for the purposes of such stock
dividend, distribution of rights or warrants, or the date on which such
reclassification, consolidation, merger, sale, lease, transfer, liquidation,
dissolution or winding up is to take place and the date of participation therein
by the holders of the shares of Preferred Stock, if any such date is to be
fixed, and such notice shall be so given in the case of any action covered by
clause (i) or (ii) above at least 20 days prior to the record date for
determining holders of the shares of Preferred Stock for purposes of such
action, and in the case of any such other action, at least 20 days prior to the
date of the taking of such proposed action or the date of participation therein
by the holders of the shares of Preferred Stock, whichever shall be the earlier.
The failure to give notice required by this Section 25 or any defect therein
shall not affect the legality or validity of the action taken by the Company or
the vote upon any such action.

                  (b) In case any Flip-In Event or Flip-Over Event shall occur,
then (i) the Company shall as soon as practicable thereafter give to each
registered holder of a Rights Certificate (or if occurring prior to the
Distribution Date, the registered holders of Common Stock), in accordance with
Section 26 hereof, a notice of the occurrence of such event, which shall specify
the event and the consequences of the event to holders of Rights under Section
11(a)(ii) or Section 13(a) hereof, and (ii) all references in the preceding
paragraph to Preferred Stock shall be deemed thereafter to refer to Common Stock
and/or, if appropriate, other securities.

                  Section 26. Notices. Notices or demands authorized by this
Agreement to be given or made by the Rights Agent or by the holder of any Rights
Certificate to or on the Company shall be sufficiently given or made if sent by

Agreement to be given or made by the Company or by the holder of any Rights
Certificate to or on the Rights Agent shall be sufficiently given or made if

prior to the Distribution Date, to the holder of certificates representing
shares of Common Stock) shall be sufficiently given or made if sent by
first-class mail, postage prepaid, addressed to such holder at the address of
such holder as shown on the registry books of the Company.

                  Section 27. Supplements and Amendments. Except as provided in
the last sentence of this Section 27, at any time when the Rights are then
redeemable, the Company may in its sole and absolute discretion and the Rights
Agent shall, if the Company so directs, supplement or amend any provision of
this Agreement in any respect without the approval of any holders of Rights or
holders of Common Stock. At any time when the Rights are not redeemable, except
as provided in the last sentence of this Section 27, the Company may and the
Rights Agent shall, if the Company so directs, supplement or amend this
Agreement without the approval of any holders of Rights in order (i) to cure any
ambiguity, (ii) to correct or supplement any provision contained herein that may
be defective or inconsistent with any other provisions herein, (iii) to shorten
or lengthen any time period hereunder or (iv) to change or supplement the
provisions hereunder in any manner that the Company may deem necessary or
desirable; provided that no such amendment or supplement shall materially
adversely affect the interests of the holders of Rights (other than an Acquiring
Person or an Affiliate or Associate of an Acquiring Person); and further
provided that this Agreement may not be supplemented or amended pursuant to this
sentence to lengthen (A) a time period relating to when the Rights may be
redeemed or (B) any other time period unless the lengthening of such other time
period is for the purpose of protecting, enhancing or clarifying the rights of,
and/or the benefits to, the holders of Rights (other than any Acquiring Person
and its Affiliates and Associates). Upon the delivery of a certificate from an
appropriate officer of the Company which states that the proposed supplement or
amendment is in compliance with the terms of this Section 27, the Rights Agent
shall execute such supplement or amendment; provided, however, that the Rights
Agent may, but shall not be obligated to, enter into any such supplement or
amendment that affects the Rights Agent's own rights, duties or immunities under
this Agreement. Notwithstanding anything contained in this Agreement to the
contrary, no supplement or amendment shall be made that decreases the Redemption
Price or shortens the Final Expiration Date.

                  Section 28. Successors. All the covenants and provisions of
this Agreement by or for the benefit of the Company or the Rights Agent shall
bind and inure to the benefit of their respective successors and assigns
hereunder.

<PAGE>
                  Section 29. Determinations and Actions by the Board of
Directors, etc. For all purposes of this Agreement, any calculation of the
number of shares of Common Stock outstanding at any particular time, including
for purposes of determining the particular percentage of such outstanding shares
of Common Stock of which any Person is the Beneficial Owner, shall be made in
accordance with the last sentence of Rule 13d-3(d)(1)(i) of the General Rules
and Regulations under the Exchange Act as in effect on the date of this
Agreement. The Board of Directors of the Company (or, as set forth herein,
certain specified members thereof) shall have the exclusive power and authority
to administer this Agreement and to exercise all rights and powers specifically
granted to the Board of Directors of the Company or to the Company, or as may be
necessary or advisable in the administration of this Agreement, including,
without limitation, the right and power to (i) interpret the provisions of this
Agreement and (ii) make all determinations deemed necessary or advisable for the
administration of this Agreement (including, without limitation, a determination
to redeem or not redeem the Rights or to amend this Agreement). All such
actions, calculations, interpretations and determinations (including, for
purposes of clause (y) below, all omissions with respect to the foregoing) that
are done or made by the Board of Directors of the Company in good faith, shall
(x) be final, conclusive and binding on the Company, the Rights Agent, the
holders of the Rights, as such, and all other parties, and (y) not subject the
Board of Directors to any liability to the holders of the Rights.

                  Section 30. Benefits of this Agreement. Nothing in this
Agreement shall be construed to give to any Person other than the Company, the
Rights Agent and the registered holders of the Rights Certificates (and, prior
to the Distribution Date, registered holders of the Common Stock) any legal or
equitable right, remedy or claim under this Agreement; but this Agreement shall
be for the sole and exclusive benefit of the Company, the Rights Agent and the
registered holders of the Rights Certificates (and, prior to the Distribution
Date, registered holders of the Common Stock).

                  Section 31. Severability. If any term, provision, covenant or
restriction of this Agreement is held by a court of competent jurisdiction or
other authority to be invalid, void or unenforceable, the remainder of the
terms, provisions, covenants and restrictions of this Agreement shall remain in
full force and effect and shall in no way be affected, impaired or invalidated;
provided, however, that notwithstanding anything in this Agreement to the
contrary, if any such term, provision, covenant or restriction is held by such
court or authority to be invalid, void or unenforceable and the Board of
Directors of the Company determines in its good faith judgment that severing the
invalid language from this Agreement would adversely affect the purpose or
effect of this Agreement, then, unless there has occurred a merger referred to
in the proviso to the first sentence of Section 23(a), the right of redemption
set forth in Section 23 hereof shall be reinstated and shall not expire until
the close of business on the tenth day following the date of such determination
by the Board of Directors of the Company or, if earlier, immediately prior to
any such merger. Without limiting the foregoing, if any provision requiring that
a determination be made by less than the entire Board of Directors of the
Company is held by a court of competent jurisdiction or other authority to be
invalid, void or unenforceable, such determination shall then be made by the
entire Board of Directors of the Company.

                  Section 32. Governing Law. This Agreement, each Right and each
Rights Certificate issued hereunder shall be deemed to be a contract made under
the laws of the State of

                                      -36-
<PAGE>
Delaware and for all purposes shall be governed by and construed in accordance
with the laws of such State applicable to contracts made and to be performed
entirely within such State.

                  Section 33. Counterparts. This Agreement may be executed in
any number of counterparts and each of such counterparts shall for all purposes
be deemed to be an original, and all such counterparts shall together constitute
but one and the same instrument.

                  Section 34. Descriptive Headings. Descriptive headings of the
several Sections of this Agreement are inserted for convenience only and shall
not control or affect the meaning or construction of any of the provisions
hereof.

                  IN WITNESS WHEREOF, the parties hereto have caused this
Agreement to be duly executed as of the day and year first above written.

                  SERIES B JUNIOR PARTICIPATING PREFERRED STOCK

                                       of

                         OCEANEERING INTERNATIONAL, INC.

             Pursuant to Section 151 of the General Corporation Law
                            of the State of Delaware


                  We, John R. Huff, President and Chief Executive Officer, and
George R. Haubenreich, Jr., Secretary, of Oceaneering International, Inc., a
corporation organized and existing under the General Corporation Law of the
State of Delaware, in accordance with the provisions of Section 103 thereof, DO
HEREBY CERTIFY:

                  That pursuant to the authority vested in the Board of
Directors in accordance with the provisions of the Certificate of Incorporation,
as amended, of the said Corporation, the said Board of Directors on November 20,
1992, adopted the following resolution creating a series of 900,000 shares of
Preferred Stock designated as "Series B Junior Participating Preferred Stock":

                  RESOLVED, that pursuant to the authority vested in the Board
         of Directors of this Corporation in accordance with the provisions of
         the Certificate of Incorporation, a series of Preferred Stock, par
         value $1.00 per share, of the Corporation be and hereby is created, and
         that the designation and number of shares thereof and the voting and
         other powers, preferences and relative, participating, optional or
         other rights of the shares of such series and the qualifications,
         limitations and restrictions thereof are as follows:

                  1. Designation and Amount. There shall be a series of
Preferred Stock that shall be designated as "Series B Junior Participating
Preferred Stock," and the number of shares constituting such series shall be
900,000. Such number of shares may be increased or decreased by resolution of
the Board of Directors; provided, however, that no decrease shall reduce the
number of shares of Series B Junior Participating Preferred Stock to less than
the number of shares then issued and outstanding plus the number of shares
issuable upon exercise of outstanding rights, options or warrants or upon
conversion of outstanding securities issued by the Corporation.

                  2. Dividends and Distributions.

                  (A) Subject to the prior and superior rights of the holders of
any shares of any series of Preferred Stock ranking prior and superior to the
shares of Series B Junior Participating

                                      A-1
<PAGE>
Preferred Stock with respect to dividends, the holders of shares of Series B
Junior Participating Preferred Stock, in preference to the holders of shares of
any class or series of stock of the Corporation ranking junior to the Series B
Preferred Stock, shall be entitled to receive, when, as and if declared by the
Board of Directors out of funds legally available for the purpose, quarterly
dividends payable in cash on the 15th day of October, January, April and July in
each year (each such date being referred to herein as a "Quarterly Dividend
Payment Date"), commencing on the first Quarterly Dividend Payment Date after
the first issuance of a share or fraction of a share of Series B Junior
Participating Preferred Stock, in an amount per share (rounded to the nearest
cent) equal to the greater of (a) $1.00 or (b) subject to the provision for
adjustment hereinafter set forth, the Adjustment Number (as defined below) times
the aggregate per share amount of all cash dividends, and the Adjustment Number
times the aggregate per share amount (payable in kind) of all non-cash dividends
or other distributions other than a dividend payable in shares of Common Stock
or a subdivision of the outstanding shares of Common Stock (by reclassification
or otherwise), declared on the Common Stock, par value $.25 per share, of the
Corporation (the "Common Stock") since the immediately preceding Quarterly
Dividend Payment Date, or, with respect to the first Quarterly Dividend Payment
Date, since the first issuance of any share or fraction of a share of Series B
Junior Participating Preferred Stock. The "Adjustment Number" shall initially be
100. In the event the Corporation shall at any time after November 20, 1992 (the
"Rights Declaration Date") (i) declare any dividend on Common Stock payable in
shares of Common Stock, (ii) subdivide the outstanding Common Stock or (iii)
combine the outstanding Common Stock into a smaller number of shares, then in
each such case the Adjustment Number in effect immediately prior to such event
shall be adjusted by multiplying such Adjustment Number by a fraction the
numerator of which is the number of shares of Common Stock outstanding
immediately after such event and the denominator of which is the number of
shares of Common Stock that were outstanding immediately prior to such event.

                  (B) The Corporation shall declare a dividend or distribution
on the Series B Junior Participating Preferred Stock as provided in paragraph
(A) above immediately after it declares a dividend or distribution on the Common
Stock (other than a dividend payable in shares of Common Stock); provided that,
in the event no dividend or distribution shall have been declared on the Common
Stock during the period between any Quarterly Dividend Payment Date and the next
subsequent Quarterly Dividend Payment Date, a dividend of $1.00 per share on the
Series B Junior Participating Preferred Stock shall nevertheless be payable on
such subsequent Quarterly Dividend Payment Date.

                  (C) Dividends shall begin to accrue and be cumulative on
outstanding shares of Series B Junior Participating Preferred Stock from the
Quarterly Dividend Payment Date next preceding the date of issue of such shares
of Series B Junior Participating Preferred Stock, unless the date of issue of
such shares is prior to the record date for the first Quarterly Dividend Payment
Date, in which case dividends on such shares shall begin to accrue from the date
of issue of such shares, or unless the date of issue is a Quarterly Dividend
Payment Date or is a date after the record date for the determination of holders
of shares of Series B Junior Participating Preferred Stock entitled to receive a
quarterly dividend and before such Quarterly Dividend Payment Date, in either of
which events such dividends shall begin to accrue and be cumulative from such
Quarterly Dividend Payment Date. Accrued but unpaid dividends shall not bear
interest. Dividends paid on the shares of Series B Junior Participating
Preferred Stock in an amount less than the total amount of such dividends at the
time accrued and payable on such

                                      A-2

<PAGE>
shares shall be allocated pro rata on a share-by-share basis among all such
shares at the time outstanding. The Board of Directors may fix a record date for
the determination of holders of shares of Series B Junior Participating
Preferred Stock entitled to receive payment of a dividend or distribution
declared thereon, which record date shall be no more than 30 days prior to the
date fixed for the payment thereof.

                  3. Voting Rights. The holders of shares of Series B Junior
Participating Preferred Stock shall have the following voting rights:

                  (A) Each share of Series B Junior Participating Preferred
Stock shall entitle the holder thereof to a number of votes equal to the
Adjustment Number on all matters submitted to a vote of the stockholders of the
Corporation.

                  (B) Except as otherwise provided herein or by law, the holders
of shares of Series B Junior Participating Preferred Stock and the holders of
shares of Common Stock shall vote together as one class on all matters submitted
to a vote of stockholders of the Corporation.

                  (C) (i) If at any time dividends on any Series B Junior
Participating Preferred Stock shall be in arrears in an amount equal to six
quarterly dividends thereon, the occurrence of such contingency shall mark the
beginning of a period (herein called a "default period") that shall extend until
such time when all accrued and unpaid dividends for all previous quarterly
dividend periods and for the current quarterly dividend period on all shares of
Series B Junior Participating Preferred Stock then outstanding shall have been
declared and paid or set apart for payment. During each default period, all
holders of Preferred Stock (including holders of the Series B Junior
Participating Preferred Stock) upon which these or like voting rights have been
conferred and are exercisable (the "Voting Preferred Stock") with dividends in
arrears in an amount equal to six quarterly dividends thereon, voting as a
class, irrespective of series, shall have the right to elect two Directors.

                  (ii) During any default period, such voting right of the
holders of Series B Junior Participating Preferred Stock may be exercised
initially at a special meeting called pursuant to subparagraph (iii) of this
Section 3(C) or at any annual meeting of stockholders, and thereafter at annual
meetings of stockholders, provided that neither such voting right nor the right
of the holders of any other series of Voting Preferred Stock, if any, to
increase, in certain cases, the authorized number of Directors shall be
exercised unless the holders of ten percent in number of shares of Voting
Preferred Stock outstanding shall be present in person or by proxy. The absence
of a quorum of the holders of Common Stock shall not affect the exercise by the
holders of Voting Preferred Stock of such voting right. At any meeting at which
the holders of Voting Preferred Stock shall exercise such voting right initially
during an existing default period, they shall have the right, voting as a class,
to elect Directors to fill such vacancies, if any, in the Board of Directors as
may then exist up to two Directors or, if such right is exercised at an annual
meeting, to elect two Directors. If the number that may be so elected at any
special meeting does not amount to the required number, the holders of the
Voting Preferred Stock shall have the right to make such increase in the number
of Directors as shall be necessary to permit the election by them of the
required number. After the holders of the Voting Preferred Stock shall have
exercised their right to elect Directors in any default period and during the
continuance of such period, the number of Directors shall not be increased or
decreased except

                                      A-3
<PAGE>
by vote of the holders of Voting Preferred Stock as herein provided or pursuant
to the rights of any equity securities ranking senior to or pari passu with the
Series B Junior Participating Preferred Stock.

                  (iii) Unless the holders of Voting Preferred Stock shall,
during an existing default period, have previously exercised their right to
elect Directors, the Board of Directors may order, or any stockholder or
stockholders owning in the aggregate not less than ten percent of the total
number of shares of Voting Preferred Stock outstanding, irrespective of series,
may request, the calling of a special meeting of the holders of Voting Preferred
Stock, which meeting shall thereupon be called by the Chairman of the Board, the
President, a Vice President or the Secretary of the Corporation. Notice of such
meeting and of any annual meeting at which holders of Voting Preferred Stock are
entitled to vote pursuant to this paragraph (C)(iii) shall be given to each
holder of record of Voting Preferred Stock by mailing a copy of such notice to
him at his last address as the same appears on the books of the Corporation.
Such meeting shall be called for a time not earlier than 20 days and not later
than 60 days after such order or request or, in default of the calling of such
meeting within 60 days after such order or request, such meeting may be called
on similar notice by any stockholder or stockholders owning in the aggregate not
less than ten percent of the total number of shares of Voting Preferred Stock
outstanding. Notwithstanding the provisions of this paragraph (C)(iii), no such
special meeting shall be called during the period within 60 days immediately
preceding the date fixed for the next annual meeting of the stockholders.

                  (iv) In any default period, the holders of Common Stock, and
other classes of stock of the Corporation if applicable, shall continue to be
entitled to elect the whole number of Directors until the holders of Voting
Preferred Stock shall have exercised their right to elect two Directors voting
as a class, after the exercise of which right (x) the Directors so elected by
the holders of Voting Preferred Stock shall continue in office until their
successors shall have been elected by such holders or until the expiration of
the default period, and (y) any vacancy in the Board of Directors may (except as
provided in paragraph (C)(ii) of this Section 3) be filled by vote of a majority
of the remaining Directors theretofore elected by the holders of the class of
stock which elected the Director whose office shall have become vacant.
References in this paragraph (C) to Directors elected by the holders of a
particular class of stock shall include Directors elected by such Directors to
fill vacancies as provided in clause (y) of the foregoing sentence.

                  (v) Immediately upon the expiration of a default period, (x)
the right of the holders of Voting Preferred Stock as a class to elect Directors
shall cease, (y) the term of any Directors elected by the holders of Voting
Preferred Stock as a class shall terminate and (z) the number of Directors shall
be such number as may be provided for in the Certificate of Incorporation or
By-Laws irrespective of any increase made pursuant to the provisions of
paragraph (C)(ii) of this Section 3 (such number being subject, however, to
change thereafter in any manner provided by law or in the Certificate of
Incorporation or By-Laws). Any vacancies in the Board of Directors effected by
the provisions of clauses (y) and (z) in the preceding sentence may be filled by
a majority of the remaining Directors.

                  (D) Except as set forth herein, holders of Series B Junior
Participating Preferred Stock shall have no special voting rights and their
consent shall not be required (except

                                      A-4
<PAGE>
to the extent they are entitled to vote with holders of Common Stock as set
forth herein) for taking any corporate action.

                  4. Certain Restrictions.

                  (A) Whenever quarterly dividends or other dividends or
distributions payable on the Series B Junior Participating Preferred Stock as
provided in Section 2 are in arrears, thereafter and until all accrued and
unpaid dividends and distributions, whether or not declared, on shares of Series
B Junior Participating Preferred Stock outstanding shall have been paid in full,
the Corporation shall not

                  (i) declare or pay dividends on, make any other distributions
on, or redeem or purchase or otherwise acquire for consideration any shares of
stock ranking junior (either as to dividends or upon liquidation, dissolution or
winding up) to the Series B Junior Participating Preferred Stock;

                  (ii) declare or pay dividends on or make any other
distributions on any shares of stock ranking on a parity (either as to dividends
or upon liquidation, dissolution or winding up) with the Series B Junior
Participating Preferred Stock, except dividends paid ratably on the Series B
Junior Participating Preferred Stock and all such parity stock on which
dividends are payable or in arrears in proportion to the total amounts to which
the holders of all such shares are then entitled;

                  (iii) redeem or purchase or otherwise acquire for
consideration shares of any stock ranking on a parity (either as to dividends or
upon liquidation, dissolution or winding up) with the Series B Junior
Participating Preferred Stock, provided that the Corporation may at any time
redeem, purchase or otherwise acquire shares of any such parity stock in
exchange for shares of any stock of the Corporation ranking junior (both as to
dividends and upon dissolution, liquidation or winding up) to the Series B
Junior Participating Preferred Stock; or

                  (iv) redeem or purchase or otherwise acquire for consideration
any shares of Series B Junior Participating Preferred Stock, or any shares of
stock ranking on a parity with the Series B Junior Participating Preferred
Stock, except in accordance with a purchase offer made in writing or by
publication (as determined by the Board of Directors) to all holders of such
shares upon such terms as the Board of Directors, after consideration of the
respective annual dividend rates and other relative rights and preferences of
the respective series and classes, shall determine in good faith will result in
fair and equitable treatment among the respective series or classes.

                  (B) The Corporation shall not permit any subsidiary of the
Corporation to purchase or otherwise acquire for consideration any shares of
stock of the Corporation unless the Corporation could, under paragraph (A) of
this Section 4, purchase or otherwise acquire such shares at such time and in
such manner.

                  5. Reacquired Shares. Any shares of Series B Junior
Participating Preferred Stock purchased or otherwise acquired by the Corporation
in any manner whatsoever shall be retired and cancelled promptly after the
acquisition thereof. All such shares shall upon their cancellation become
authorized but unissued shares of Preferred Stock and may be reissued as

                                      A-5
<PAGE>
part of a new series of Preferred Stock to be created by resolution or
resolutions of the Board of Directors, subject to the conditions and
restrictions on issuance set forth herein.

                  6. Liquidation, Dissolution or Winding Up.

                  (A) Upon any liquidation (voluntary or otherwise), dissolution
or winding up of the Corporation, no distribution shall be made to the holders
of shares of stock ranking junior (either as to dividends or upon liquidation,
dissolution or winding up) to the Series B Junior Participating Preferred Stock
unless, prior thereto, the holders of shares of Series B Junior Participating
Preferred Stock shall have received $100 per share, plus an amount equal to
accrued and unpaid dividends and distributions thereon, whether or not declared,
to the date of such payment (the "Series B Liquidation Preference"). Following
the payment of the full amount of the Series B Liquidation Preference, no
additional distributions shall be made to the holders of shares of Series B
Junior Participating Preferred Stock unless, prior thereto, the holders of
shares of Common Stock shall have received an amount per share (the "Common
Adjustment") equal to the quotient obtained by dividing (i) the Series B
Liquidation Preference by (ii) the Adjustment Number. Following the payment of
the full amount of the Series B Liquidation Preference and the Common Adjustment
in respect of all outstanding shares of Series B Junior Participating Preferred
Stock and Common Stock, respectively, holders of Series B Junior Participating
Preferred Stock and holders of shares of Common Stock shall receive their
ratable and proportionate share of the remaining assets to be distributed in the
ratio of the Adjustment Number to 1 with respect to such Preferred Stock and
Common Stock, on a per share basis, respectively.

                  (B) In the event, however, that there are not sufficient
assets available to permit payment in full of the Series B Liquidation
Preference and the liquidation preferences of all other series of Preferred
Stock, if any, that rank on a parity with the Series B Junior Participating
Preferred Stock, then such remaining assets shall be distributed ratably to the
holders of such parity shares in proportion to their respective liquidation
preferences. In the event, however, that there are not sufficient assets
available to permit payment in full of the Common Adjustment, then such
remaining assets shall be distributed ratably to the holders of Common Stock.

                  7. Consolidation, Merger, etc. In case the Corporation shall
enter into any consolidation, merger, combination, or other transaction in which
the shares of Common Stock are exchanged for or changed into other stock or
securities, cash and/or any other property, then in any such case the shares of
Series B Junior Participating Preferred Stock shall at the same time be
similarly exchanged or changed in an amount per share equal to the Adjustment
Number times the aggregate amount of stock, securities, cash and/or any other
property (payable in kind), as the case may be, into which or for which each
share of Common Stock is changed or exchanged.

                  8. Redemption.

                  (A) The Corporation, at its option, may redeem shares of the
Series B Junior Participating Preferred Stock in whole at any time and in part
from time to time, at a redemption price equal to the Adjustment Number times
the current per share market price (as such term is

                                      A-6
<PAGE>
hereinafter defined) of the Common Stock on the date of the mailing of the
notice of redemption, together with unpaid accumulated dividends to the date of
such redemption. The "current per share market price" on any date shall be
deemed to be the average of the closing price per share of such Common Stock for
the ten consecutive Trading Days (as such term is hereinafter defined)
immediately prior to such date; provided, however, that in the event that the
current per share market price of the Common Stock is determined during a period
following the announcement of (A) a dividend or distribution on the Common Stock
other than a regular quarterly cash dividend or (B) any subdivision, combination
or reclassification of such Common Stock and the ex-dividend date for such
dividend or distribution, or the record date for such subdivision, combination
or reclassification, shall not have occurred prior to the commencement of such
ten Trading Day period, then, and in each such case, the current per share
market price shall be properly adjusted to take into account ex-dividend
trading. The closing price for each day shall be the last sales price, regular
way, or, in case no such sale takes place on such day, the average of the
closing bid and asked prices, regular way, in either case as reported in the
principal consolidated transaction reporting system with respect to securities
listed or admitted to trading on the New York Stock Exchange, or, if the Common
Stock is not listed or admitted to trading on the New York Stock Exchange, as
reported in the principal transaction reporting system with respect to
securities listed on the principal national securities exchange on which the
Common Stock is listed or admitted to trading or, if the Common Stock is not
listed or admitted to trading on any national securities exchange, the last
quoted sales price or, if not so quoted, the average of the high bid and low
asked prices in the over-the-counter market, as reported by the National
Association of Securities Dealers, Inc. Automated Quotations System or such
other self-regulatory organization or registered securities information
processor (as such terms are used under the Securities Exchange Act of 1934, as
amended) that then reports information concerning the Common Stock or, if on any
such date the Common Stock is not quoted by any such entity, the average of the
closing bid and asked prices as furnished by a professional market maker making
a market in the Common Stock selected by the Board of Directors of the
Corporation. If on any such date no such market maker is making a market in the
Common Stock, the fair value of the Common Stock on such date as determined in
good faith by the Board of Directors of the Corporation shall be used. The term
"Trading Day" shall mean a day on which the principal national securities
exchange on which the Common Stock is listed or admitted to trading is open for
the transaction of business or, if the Common Stock is not listed or admitted to
trading on any national securities exchange, a Monday, Tuesday, Wednesday,
Thursday or Friday on which banking institutions in the State of New York are
not authorized or obligated by law or executive order to close.

                  (B) In the event that fewer than all the outstanding shares of
the Series B Junior Participating Preferred Stock are to be redeemed, the number
of shares to be redeemed shall be determined by the Board of Directors and the
shares to be redeemed shall be determined by lot or pro rata as may be
determined by the Board of Directors or by any other method that may be
determined by the Board of Directors in its sole discretion to be equitable.

                  (C) Notice of any such redemption shall be given by mailing to
the holders of the shares of Series B Junior Participating Preferred Stock to be
redeemed a notice of such redemption, first class postage prepaid, not later
than the fifteenth day and not earlier than the sixtieth day before the date
fixed for redemption, at their last address as the same shall appear upon the
books of the Corporation. Each such notice shall state: (i) the redemption date;
(ii) the

                                      A-7
<PAGE>
number of shares to be redeemed and, if fewer than all the shares held by such
holder are to be redeemed, the number of such shares to be redeemed from such
holder; (iii) the redemption price; (iv) the place or places where certificates
for such shares are to be surrendered for payment of the redemption price; and
(v) that dividends on the shares to be redeemed will cease to accrue on the
close of business on such redemption date. Any notice that is mailed in the
manner herein provided shall be conclusively presumed to have been duly given,
whether or not the stockholder received such notice, and failure duly to give
such notice by mail, or any defect in such notice, to any holder of Series B
Junior Participating Preferred Stock shall not affect the validity of the
proceedings for the redemption of any other shares of Series B Junior
Participating Preferred Stock that are to be redeemed. On or after the date
fixed for redemption as stated in such notice, each holder of the shares called
for redemption shall surrender the certificate evidencing such shares to the
Corporation at the place designated in such notice and shall thereupon be
entitled to receive payment of the redemption price. If fewer than all the
shares represented by any such surrendered certificate are redeemed, a new
certificate shall be issued representing the unredeemed shares.

                  (D) The shares of Series B Junior Participating Preferred
Stock shall not be subject to the operation of any purchase, retirement or
sinking fund.

                  9. Ranking. The Series B Junior Participating Preferred Stock
shall rank junior to all other series of the Corporation's Preferred Stock as to
the payment of dividends and the distribution of assets, unless the terms of any
such series shall provide otherwise.

                  10. Amendment. At any time that any shares of Series B Junior
Participating Preferred Stock are outstanding, the Certificate of Incorporation,
as amended, of the Corporation shall not be amended in any manner which would
materially alter or change the powers, preferences or special rights of the
Series B Junior Participating Preferred Stock so as to affect them adversely
without the affirmative vote of the holders of a majority or more of the
outstanding shares of Series B Junior Participating Preferred Stock, voting
separately as a class.

                  11. Fractional Shares. Series B Junior Participating Preferred
Stock may be issued in fractions of a share that shall entitle the holder, in
proportion to such holder's fractional shares, to exercise voting rights,
receive dividends, participate in distributions and to have the benefit of all
other rights of holders of Series B Junior Participating Preferred Stock.

                         OCEANEERING INTERNATIONAL, INC.


                  This certifies that _____________________, or registered
assigns, is the registered owner of the number of Rights set forth above, each
of which entitles the owner thereof, subject to the terms, provisions and
conditions of the Rights Agreement, dated as of November 20, 1992 as amended and
restated as of November 16, 2001 as it may from time to time be supplemented or
amended (the "Rights Agreement"), between Oceaneering International, Inc., a
Delaware corporation (the "Company"), and EquiServe Trust Company, N.A., a
national banking association (the "Rights Agent"), to purchase from the Company
at any time prior to 5:00 p.m. (New York, New York time) on November 16, 2011 at
the principal office or offices of the Rights Agent designated for such purpose,
or its successors as Rights Agent, one one-hundredth of a fully paid,
nonassessable share (a "Fractional Share") of Series B Junior Participating
Preferred Stock, par value $1.00 per share (the "Preferred Stock"), of the
Company, at a purchase price of $60 per one one-hundredth of a share (the
"Purchase Price"), upon presentation and surrender of this Rights Certificate
with the Form of Election to Purchase and related Certificate set forth on the
reverse hereof duly executed. The Purchase Price may be paid in cash or by
certified check, cashier's or official bank check or bank draft payable to the
order of the Company or the Rights Agent. The number of Rights evidenced by this
Rights Certificate (and the number of shares that may be purchased upon exercise
thereof) set forth above, and the Purchase Price per Fractional Share set forth
above, are the number and Purchase Price as of November 20, 1992, based on the
Preferred Stock as constituted at such date. The Company reserves the right to
require prior to the occurrence of a Triggering Event (as such term is defined
in the Rights Agreement) that a number of Rights be exercised so that only whole
shares of Preferred Stock will be issued.

                  From and after the first occurrence of a Triggering Event (as
such term is defined in the Rights Agreement), if the Rights evidenced by this
Rights Certificate are beneficially owned by or transferred to (i) an Acquiring
Person or an Associate or Affiliate of an Acquiring Person (as such terms are
defined in the Rights Agreement), (ii) a transferee of any such

                                      B-1
<PAGE>
Acquiring Person, Associate or Affiliate, or (iii) under certain circumstances
specified in the Rights Agreement, a transferee of a person who, concurrently
with or after such transfer, became an Acquiring Person or an Affiliate or
Associate of an Acquiring Person, such Rights shall, with certain exceptions,
become null and void in the circumstances set forth in the Rights Agreement, and
no holder hereof shall have any rights whatsoever with respect to such Rights
from and after the occurrence of such Triggering Event.

                  As provided in the Rights Agreement, the Purchase Price and
the number and kind of shares of Preferred Stock or other securities or assets
that may be purchased upon the exercise of the Rights evidenced by this Rights
Certificate are subject to modification and adjustment upon the happening of
certain events, including Triggering Events.

                  This Rights Certificate is subject to all of the terms,
provisions and conditions of the Rights Agreement, which terms, provisions and
conditions are hereby incorporated herein by reference and made a part hereof
and to which Rights Agreement reference is hereby made for a full description of
the rights, limitations of rights, obligations, duties and immunities hereunder
of the Rights Agent, the Company and the holders of the Rights Certificates,
which limitations of rights include the temporary suspension of the
exercisability of such Rights under the specific circumstances set forth in the
Rights Agreement. Copies of the Rights Agreement are on file at the
above-mentioned office of the Rights Agent and are also available upon written
request to the Company.

                  This Rights Certificate, with or without other Rights
Certificates, upon surrender at the principal office or offices of the Rights
Agent designated for such purpose, may be exchanged for another Rights
Certificate or Rights Certificates of like tenor and date evidencing Rights
entitling the holder to purchase a like aggregate number of Fractional Shares of
Preferred Stock as the Rights evidenced by the Rights Certificate or Rights
Certificates surrendered shall have entitled such holder to purchase. If this
Rights Certificate shall be exercised in part, the holder shall be entitled to
receive upon surrender hereof another Rights Certificate or Rights Certificates
for the number of whole Rights not exercised.

                  Subject to the provisions of the Rights Agreement, the Rights
evidenced by this Certificate (i) may be redeemed by the Company at its option
at a redemption price of $.01 per Right, payable, at the election of the
Company, in cash or shares of Common Stock or such other consideration as the
Board of Directors may determine, at any time prior to the earlier of the close
of business on (a) the tenth day following the first public announcement of the
occurrence of a Flip-In Event (as such time period may be extended or shortened
pursuant to the Rights Agreement) and (b) the Expiration Date (as such term is
defined in the Rights Agreement) or (ii) may be exchanged in whole or in part
for shares of Common Stock and/or other equity securities of the Company deemed
to have the same value as shares of Common Stock, at any time prior to a
person's becoming the beneficial owner of 50% or more of the shares of Common
Stock outstanding or the occurrence of a Flip-Over Event.


                  No fractional shares of Preferred Stock are required to be
issued upon the exercise of any Right or Rights evidenced hereby (other than,
except as set forth above, fractions that are integral multiples of a Fractional
Share of Preferred Stock, which may, at the election of the

                                      B-2

Company, be evidenced by depositary receipts), but in lieu thereof a cash
payment may be made, as provided in the Rights Agreement.

                  No holder of this Rights Certificate, as such, shall be
entitled to vote or receive dividends or be deemed for any purpose the holder of
shares of Preferred Stock or of any other securities of the Company that may at
any time be issuable on the exercise hereof, nor shall anything contained in the
Rights Agreement or herein be construed to confer upon the holder hereof, as
such, any of the rights of a stockholder of the Company or any right to vote for
the election of directors or upon any matter submitted to stockholders at any
meeting thereof, or to give or withhold consent to any corporate action, or to
receive notice of meetings or other actions affecting stockholders (except as
provided in the Rights Agreement), or to receive dividends or subscription
rights, or otherwise, until the Right or Rights evidenced by this Rights
Certificate shall have been exercised as provided in the Rights Agreement.

                  This Rights Certificate shall not be valid or obligatory for
any purpose until it shall have been countersigned by the Rights Agent.

                                                                       EXHIBIT C

UNDER CERTAIN CIRCUMSTANCES SET FORTH IN THE RIGHTS AGREEMENT, RIGHTS
BENEFICIALLY OWNED BY OR TRANSFERRED TO ANY PERSON WHO IS, WAS OR BECOMES AN
ACQUIRING PERSON OR AN AFFILIATE OR ASSOCIATE THEREOF (AS SUCH TERMS ARE DEFINED
IN THE RIGHTS AGREEMENT), AND CERTAIN TRANSFEREES THEREOF, WILL BECOME NULL AND
VOID AND WILL NO LONGER BE TRANSFERABLE.

                                SUMMARY OF RIGHTS

                  On November 20, 1992, the Board of Directors of Oceaneering
International, Inc. (the "Company") declared a dividend of one right ("Right")
for each outstanding share of the Company's Common Stock, par value $.25 per
share ("Common Stock"), to stockholders of record at the close of business on
December 4, 1992. Each Right entitles the registered holder to purchase from the
Company a unit consisting of one one-hundredth of a share (a "Fractional
Share") of Series B Junior Participating Preferred Stock, par value $1.00
per share (the "Preferred Stock"), at a purchase price of $60 per Fractional
Share, subject to adjustment (the "Purchase Price"). The description and terms
of the Rights are set forth in a Rights Agreement dated as of November 20, 1992
as amended and restated as of November 16, 2001 as it may from time to time be
further supplemented or amended (the "Rights Agreement") between the Company and
EquiServe Trust Company, N.A., as Rights Agent.

                  Initially, the Rights will be attached to all certificates
representing outstanding shares of Common Stock, and no separate certificates
for the Rights ("Rights Certificates") will be distributed. The Rights will
separate from the Common Stock and a "Distribution Date" will occur, with
certain exceptions, upon the earlier of (i) ten days following a public
announcement that a person or group of affiliated or associated persons (an
"Acquiring Person") has acquired, or obtained the right to acquire, beneficial
ownership of 15% or more of the outstanding shares of Common Stock (the date of
the announcement being the "Stock Acquisition Date"), or (ii) ten business days
following the commencement of a tender offer or exchange offer that would result
in a person's becoming an Acquiring Person. In certain circumstances, the
Distribution Date may be deferred by the Board of Directors. Certain inadvertent
acquisitions will not result in a person's becoming an Acquiring Person if the
person promptly divests itself of sufficient Common Stock. Until the
Distribution Date, (a) the Rights will be evidenced by the Common Stock
certificates (together with a copy of this Summary of Rights or bearing the
notation referred to below) and will be transferred with and only with such
Common Stock certificates, (b) new Common Stock certificates issued after
December 4, 1992 will contain a notation incorporating the Rights Agreement by
reference and (c) the surrender for transfer of any certificate for Common Stock
(with or without a copy of this Summary of Rights) will also constitute the
transfer of the Rights associated with the Common Stock represented by such
certificate.

                  The Rights are not exercisable until the Distribution Date and
will expire at the close of business on November 16, 2011, unless earlier
redeemed or exchanged by the Company as described below.

                  As soon as practicable after the Distribution Date, Rights
Certificates will be mailed to holders of record of Common Stock as of the close
of business on the Distribution

                                      C-1
<PAGE>
Date and, from and after the Distribution Date,
the separate Rights Certificates alone will represent the Rights. All shares of
Common Stock issued prior to the Distribution Date will be issued with Rights.
Shares of Common Stock issued after the Distribution Date in connection with
certain employee benefit plans or upon conversion of certain securities will be
issued with Rights. Except as otherwise determined by the Board of Directors, no
other shares of Common Stock issued after the Distribution Date will be issued
with Rights.

                  In the event (a "Flip-In Event") that a person becomes an
Acquiring Person (except pursuant to a tender or exchange offer for all
outstanding shares of Common Stock at a price and on terms that a majority of
the independent directors of the Company determines to be fair to and otherwise
in the best interests of the Company and its stockholders (a "Permitted
Offer")), each holder of a Right will thereafter have the right to receive, upon
exercise of such Right, a number of shares of Common Stock (or, in certain
circumstances, cash, property or other securities of the Company) having a
Current Market Price (as defined in the Rights Agreement) equal to two times the
exercise price of the Right. Notwithstanding the foregoing, following the
occurrence of any Triggering Event, all Rights that are, or (under certain
circumstances specified in the Rights Agreement) were, beneficially owned by or
transferred to an Acquiring Person (or by certain related parties) will be null
and void in the circumstances set forth in the Rights Agreement. However, Rights
are not exercisable following the occurrence of any Flip-In Event until such
time as the Rights are no longer redeemable by the Company as set forth below.

                  In the event (a "Flip-Over Event") that, at any time from and
after the time an Acquiring Person becomes such, (i) the Company is acquired in
a merger or other business combination transaction (other than certain mergers
that follow a Permitted Offer), or (ii) 50% or more of the Company's assets,
cash flow or earning power is sold or transferred, each holder of a Right
(except Rights that are voided as set forth above) shall thereafter have the
right to receive, upon exercise, a number of shares of common stock of the
acquiring company having a Current Market Price equal to two times the exercise
price of the Right. Flip-In Events and Flip-Over Events are collectively
referred to as "Triggering Events."

                  The number of outstanding Rights associated with a share of
Common Stock, or the number of Fractional Shares of Preferred Stock issuable
upon exercise of a Right and the Purchase Price, are subject to adjustment in
the event of a stock dividend on, or a subdivision, combination or
reclassification of, the Common Stock occurring prior to the Distribution Date.
The Purchase Price payable, and the number of Fractional Shares of Preferred
Stock or other securities or property issuable, upon exercise of the Rights are
subject to adjustment from time to time to prevent dilution in the event of
certain transactions affecting the Preferred Stock.

                  With certain exceptions, no adjustment in the Purchase Price
will be required until cumulative adjustments amount to at least 1% of the
Purchase Price. No fractional shares of Preferred Stock that are not integral
multiples of a Fractional Share are required to be issued upon exercise of
Rights and, in lieu thereof, an adjustment in cash may be made based on the
market price of the Preferred Stock on the last trading date prior to the date
of exercise. Pursuant to the Rights Agreement, the Company reserves the right to
require prior to the occurrence of a Triggering Event that, upon any exercise of
Rights, a number of Rights be exercised so that only whole shares of Preferred
Stock will be issued.

<PAGE>

                  At any time until ten days following the first date of public
announcement of the occurrence of a Flip-In Event, the Company may redeem the
Rights in whole, but not in part, at a price of $.01 per Right, payable, at the
option of the Company, in cash, shares of Common Stock or such other
consideration as the Board of Directors may determine. Immediately upon the
effectiveness of the action of the Board of Directors ordering redemption of the
Rights, the Rights will terminate and the only right of the holders of Rights
will be to receive the $.01 redemption price.

                  At any time after the occurrence of a Flip-In Event and prior
to a person's becoming the beneficial owner of 50% or more of the shares of
Common Stock then outstanding or the occurrence of a Flip-Over Event, the
Company may exchange the Rights (other than Rights owned by an Acquiring Person
or an affiliate or an associate of an Acquiring Person, which will have become
void), in whole or in part, at an exchange ratio of one share of Common Stock,
and/or other equity securities deemed to have the same value as one share of
Common Stock, per Right, subject to adjustment.

                  Until a Right is exercised, the holder thereof, as such, will
have no rights as a stockholder of the Company, including, without limitation,
the right to vote or to receive dividends.

                  Other than the decreases in the redemption price and
shortening of the Final Expiration Date, any of the provisions of the Rights
Agreement may be amended by the Board of Directors of the Company as long as the
Rights are redeemable. Thereafter, the provisions of the Rights Agreement other
than the redemption price may be amended by the Board of Directors in order to
cure any ambiguity, defect or inconsistency, to make changes that do not
materially adversely affect the interests of holders of Rights (excluding the
interests of any Acquiring Person), or to shorten or lengthen any time period
under the Rights Agreement; provided, however, that no amendment to lengthen the
time period governing redemption shall be made at such time as the Rights are
not redeemable.

                  A copy of the Rights Agreement has been filed with the
Securities and Exchange Commission as an exhibit to a Current Report on Form
8-K. A copy of the Rights Agreement is available free of charge from the
Company. This summary description of the Rights does not purport to be complete
and is qualified in its entirety by reference to the Rights Agreement, which is
incorporated herein by reference.
