ITEM 1.           DESCRIPTION OF SECURITIES TO BE REGISTERED.

Introduction
- ------------
                  On October 29, 1998, the Board of Directors of Anadarko
Petroleum Corporation (the "Company") declared a dividend of one preferred share
purchase right (a "Right") for each outstanding share of common stock, par value
$0.10 per share, of the Company (the "Common Shares"). The dividend is payable
on November 10, 1998 (the "Record Date") to the stockholders of record on that
date. The description and terms of the Rights are set forth in an Agreement,
dated as of October 29, 1998 (the "Agreement"), between the Company and The
Chase Manhattan Bank, as Rights Agent (the "Rights Agent").

Purchase Price
- --------------
                  Each Right entitles the registered holder to purchase from the
Company one one-thousandth of a share of Series C Junior Participating Preferred
Stock of the Company, par value $1.00 per share (the "Preferred Shares"), at a
price of $175 per one one-thousandth of a Preferred Share (the "Purchase
Price"), subject to adjustment.

Flip-In
- -------
                  In the event that any person or group of affiliated or
associated persons acquires beneficial ownership of 15% or more of the
outstanding Common Shares (an "Acquiring Person"), each holder of a Right, other
than Rights beneficially owned by the Acquiring Person (which will thereafter be
void), will thereafter have the right to receive upon exercise that number of
Common Shares having a market value of two times the exercise price of the
Right.

Flip-Over
- ---------
                  If the Company is acquired in a merger or other business
combination transaction or 50% or more of its consolidated assets or earning
power are sold after a person or group has become an Acquiring Person, each
holder of a Right (other than Rights beneficially owned by Acquiring Person,
which will be void) will thereafter have the right to receive that number of
shares of common stock of the acquiring company which at the time of such
transaction will have a market value of two times the exercise price of the
Right.

Distribution Date
- -----------------
                  The distribution date is the earlier of

                  (i) 10 days following a public announcement that a person or
group of affiliated or associated persons have acquired beneficial ownership of
15% or more of the outstanding Common Shares; or

                  (ii) 10 business days (or such later date as may be determined
by action of the Board of Directors of the Company prior to such time as any
person or group of affiliated 

                                       2
<PAGE>

persons becomes an Acquiring Person) following the commencement of, or
announcement of an intention to make, a tender offer or exchange offer the
consummation of which would result in the beneficial ownership by a person or
group of 15% or more of the outstanding Common Shares.

Transfer and Detachment
- -----------------------
                  Until the Distribution Date, the Rights will be evidenced,
with respect to any of the Common Share certificates outstanding as of the
Record Date, by such Common Share certificate with a copy of the Summary of
Rights to Purchase Preferred Shares (the "Summary of Rights") attached thereto.
Until the Distribution Date (or earlier redemption or expiration of the Rights),
the Rights will be transferred with and only with the Common Shares, and
transfer of those certificates will also constitute transfer of these Rights.

                  As soon as practicable following the Distribution Date,
separate certificates evidencing the Rights ("Right Certificates") will be
mailed to holders of record of the Common Shares as of the close of business on
the Distribution Date and such separate Right Certificates alone will thereafter
evidence the Rights.

Exercisability
- --------------
                  The Rights are not exercisable until the Distribution Date.
The Rights will expire on November 10, 2008 (the "Final Expiration Date"),
unless the Final Expiration Date is extended or unless the Rights are earlier
redeemed or exchanged by the Company, in each case, as described below.

Adjustments
- -----------
                  The Purchase Price payable, and the number of Preferred Shares
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
stock dividends, stock splits, reclassifications, or certain distributions with
respect to the Preferred Shares. The number of outstanding Rights and the number
of one one-thousandths of a Preferred Share issuable upon exercise of each Right
are also subject to adjustment if, prior to the Distribution Date, there is a
stock split of the Common Shares or a stock dividend on the Common Shares
payable in Common Shares or subdivisions, consolidations or combinations of the
Common Shares. With certain exceptions, no adjustment in the Purchase Price will
be required until cumulative adjustments require an adjustment of at least 1% in
such Purchase Price. No fractional Preferred Shares will be issued (other than
fractions which are integral multiples of one one-thousandth of a Preferred
Share, which may, at the election of the Company, be evidenced by depositary
receipts) and, in lieu thereof, an adjustment in cash will be made based on the
market price of the Preferred Shares on the last trading day prior to the date
of exercise.

                                       3
<PAGE>

Preferred Shares
- ----------------
                  Each Preferred Share will be entitled to a minimum
preferential quarterly dividend payment of $1 per share but will be entitled to
an aggregate dividend of 1,000 times the dividend declared per Common Share. In
the event of liquidation, the holders of the Preferred Shares will be entitled
to a minimum preferential liquidation payment of $1,000 per share but will be
entitled to an aggregate payment of 1,000 times the payment made per Common
Share. Each Preferred Share will have 1,000 votes, voting together with the
Common Shares. Finally, in the event of any merger, consolidation or other
transaction in which Common Shares are exchanged, each Preferred Share will be
entitled to receive 1,000 times the amount received per Common Share.
These rights are protected by customary antidilution provisions.

                  The value of the one one-thousandth interest in a Preferred
Share purchasable upon exercise of each Right should, because of the nature of
the Preferred Shares' dividend, liquidation and voting rights, approximate the
value of one Common Share.

Exchange
- --------
                  At any time after any person or group becomes an Acquiring
Person, and prior to the acquisition by such person or group of 50% or more of
the outstanding Common Shares, the Board of Directors of the Company may
exchange the Rights (other than Rights owned by the Acquiring Person, which will
have become void), in whole or in part, at an exchange ratio of one Common
Share, or one one-thousandth of a Preferred Share (subject to adjustment).

Redemption
- ----------
                  At any time prior to any person or group becoming an Acquiring
Person, the Board of Directors of the Company may redeem the Rights in whole,
but not in part, at a price of $.01 per Right (the "Redemption Price"). The
redemption of the Rights may be made effective at such time on such basis with
such conditions as the Board of Directors in its sole discretion may establish.
Immediately upon any redemption of the Rights, the right to exercise the Rights
will terminate and the only right of the holders of Rights will be to receive
the Redemption Price.

Amendments
- ----------
                  The terms of the Rights may be amended by the Board of
Directors of the Company without the consent of the holders of the Rights,
including an amendment to lower certain thresholds described above to not less
than the greater of (i) the sum of .001% and the largest percentage of the
outstanding Common Shares then known to the Company to be beneficially owned by
any person or group of affiliated or associated persons and (ii) 10%, except
that from and after such time as any person or group of affiliated or associated
persons becomes an Acquiring Person no such amendment may adversely affect the
interests of the holders of the Rights.

Rights and Holders
- ------------------
                  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.

                  The Agreement is attached hereto as an exhibit and is
incorporated herein by reference. The foregoing description of the Rights does

                  Agreement, dated as of October 29, 1998, between Anadarko
Petroleum Corporation, a Delaware corporation (the "Company"), and The Chase 
Manhattan Bank, as rights agent (the "Rights Agent").

                  The Board of Directors of the Company has authorized and
declared a dividend of one preferred share purchase right (a "Right") for each
Common Share (as hereinafter defined) of the Company outstanding on November 10,
1998 (the "Record Date"), each Right representing the right to purchase one
one-thousandth of a Preferred Share (as hereinafter defined), upon the terms and
subject to the conditions herein set forth, and has further authorized and
directed the issuance of one Right with respect to each Common Share that shall
become outstanding between the Record Date and the earliest of the Distribution
Date, the Redemption Date and the Final Expiration Date (as such terms are
hereinafter defined).

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

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

                  (a) "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 Common Shares of the Company then
outstanding, but shall not include the Company, any Subsidiary of the Company,
any employee benefit plan of the Company or any Subsidiary of the Company, or
any entity holding Common Shares for or pursuant to the terms of any such plan.
Notwithstanding the foregoing, no Person shall become an "Acquiring Person" as
the result of an 

                                      -1-
<PAGE>

acquisition of Common Shares by the Company which, by reducing the number of
Common Shares of the Company outstanding, increases the proportionate number of
Common Shares of the Company beneficially owned by such Person to 15% or more of
the Common Shares of the Company then outstanding; provided, however, that, if a
Person shall become the Beneficial Owner of 15% or more of the Common Shares of
the Company then outstanding by reason of share purchases by the Company and
shall, after such share purchases by the Company, become the Beneficial Owner of
any additional Common Shares of the Company, then such Person shall be deemed to
be an "Acquiring Person." Notwithstanding the foregoing, if the Board of
Directors of the Company determines in good faith that a Person who would
otherwise be an "Acquiring Person," as defined pursuant to the foregoing
provisions of this paragraph (a), has become such inadvertently, and such Person
divests as promptly as practicable a sufficient number of Common Shares so that
such Person would no longer be an "Acquiring Person," as defined pursuant to the
foregoing provisions of this paragraph (a), then such Person shall not be deemed
to be an "Acquiring Person" for any purposes of this Agreement.

                  (b) "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.

                  (c) "Associate" 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.

                                      -2-
<PAGE>

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

                  (i) which such Person or any of such Person's Affiliates or
         Associates beneficially owns, directly or indirectly;

                  (ii) which such Person or any of such Person's Affiliates or
         Associates has (A) the right to acquire (whether such right is
         exercisable immediately or only after the passage of time) pursuant to
         any agreement, arrangement or understanding (other than customary
         agreements with and between underwriters and selling group members with
         respect to a bona fide public offering of securities), or upon the
         exercise of conversion rights, exchange rights, rights (other than
         these Rights), warrants or options, or otherwise; provided, however,
         that a Person shall not be deemed the Beneficial Owner of, or to
         beneficially own, securities tendered pursuant to a tender or exchange
         offer made by or on behalf of such Person or any of such Person's
         Affiliates or Associates until such tendered securities are accepted
         for purchase or exchange; or (B) the right to vote pursuant to any
         agreement, arrangement or understanding; provided, however, that a
         Person shall not be deemed the Beneficial Owner of, or to beneficially
         own, any security if the agreement, arrangement or understanding to
         vote such security (1) arises solely from a revocable proxy or consent
         given to such Person in response to a public proxy or consent
         solicitation made pursuant to, and in accordance with, the applicable
         rules and regulations promulgated under the Exchange Act and (2) is not
         also then reportable on Schedule 13D under the Exchange Act (or any
         comparable or successor report); or

                                      -3-
<PAGE>

                  (iii) which are beneficially owned, directly or indirectly, by
         any other Person with which such Person or any of such Person's
         Affiliates or Associates has any agreement, arrangement or
         understanding (other than customary agreements with and between
         underwriters and selling group members with respect to a bona fide
         public offering of securities) for the purpose of acquiring, holding,
         voting (except to the extent contemplated by the proviso to Section
         1(c)(ii)(B) hereof) or disposing of any securities of the Company.

                  Notwithstanding anything in this definition of Beneficial
Ownership to the contrary, the phrase "then outstanding," when used with
reference to a Person's Beneficial Ownership of securities of the Company, shall
mean the number of such securities then issued and outstanding together with the
number of such securities not then actually issued and outstanding which such
Person would be deemed to own beneficially hereunder.

                  (e) "Business Day" shall mean any day other than a Saturday, a
Sunday, or a day on which banking institutions in New Jersey or Texas are
authorized or obligated by law or executive order to close.

                  (f) "Close of Business" on any given date shall mean 5:00
P.M., Houston time, on such date; provided, however, that, if such date is not a
Business Day, it shall mean 5:00 P.M., Houston time, on the next succeeding
Business Day.

                  (g) "Common Shares" when used with reference to the Company

                  Section 3. Issue of Right Certificates. (a) Until the earlier
of (i) the tenth day after the Shares Acquisition Date or (ii) the tenth
Business Day (or such later date as may be determined by action of the Board of

Company for or pursuant to the terms of any such plan) of, or of the first

Subsidiary of the Company or any entity holding Common Shares of the Company for
or pursuant to the terms of any such plan) to commence, a tender or exchange

then outstanding Common Shares of the Company (including any such date which is
after the date of this Agreement and prior to the issuance of the Rights; the

Certificates) and not by separate Right Certificates, and (y) the right to

countersign, 


                                      -7-
<PAGE>

and the Company will send or cause to be sent (and the Rights Agent will, if
requested, send) by first-class, insured, postage-prepaid mail, to each record
holder of Common Shares of the Company as of the Close of Business on the
Distribution Date, at the address of such holder shown on the records of the
Company, a Right Certificate, in substantially the form of Exhibit B hereto (a
"Right Certificate"), evidencing one Right for each Common Share so held. As of
the Distribution Date, the Rights will be evidenced solely by such Right
Certificates.

                  (b) On the Record Date, or as soon as practicable thereafter,
the Company will send a copy of a Summary of Rights to Purchase Preferred
Shares, in substantially the form of Exhibit C hereto (the "Summary of Rights"),
by first-class, postage-prepaid mail, to each record holder of Common Shares 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 Shares of
the Company outstanding as of the Record Date, until the Distribution Date, the
Rights will be evidenced by such certificates registered in the names of the
holders thereof together with a copy of the Summary of Rights attached thereto.
Until the Distribution Date (or the earlier of the Redemption Date or the Final
Expiration Date), the surrender for transfer of any certificate for Common
Shares of the Company outstanding on the Record Date, with or without a copy of
the Summary of Rights attached thereto, shall also constitute the transfer of
the Rights associated with the Common Shares of the Company represented thereby.

                  (c) Certificates for Common Shares which become outstanding
(including, without limitation, reacquired Common Shares referred to in the last
sentence of this paragraph (c)) after the Record Date but prior to the earliest
of the Distribution Date, the Redemption Date 


                                      -8-
<PAGE>

or the Final Expiration Date shall have impressed on, printed on, written on or
otherwise affixed to them the following legend:

         This certificate also evidences and entitles the holder hereof to
         certain rights as set forth in an Agreement between Anadarko Petroleum
         Corporation and The Chase Manhattan Bank, dated as of October 29, 1998,
         as it may be amended from time to time (the "Agreement"), the terms of
         which are hereby incorporated herein by reference and a copy of which
         is on file at the principal executive offices of Anadarko Petroleum
         Corporation. Under certain circumstances, as set forth in the
         Agreement, such Rights (as defined in the Agreement) will be evidenced
         by separate certificates and will no longer be evidenced by this
         certificate. Anadarko Petroleum Corporation will mail to the holder of
         this certificate a copy of the Agreement without charge after receipt
         of a written request therefor. As set forth in the Agreement, Rights
         beneficially owned by any Person (as defined in the Agreement) who
         becomes an Acquiring Person (as defined in the Agreement) become null
         and void.

With respect to such certificates containing the foregoing legend, until the
Distribution Date, the Rights associated with the Common Shares of the Company
represented by such certificates shall be evidenced by such certificates alone,
and the surrender for transfer of any such certificate shall also constitute the
transfer of the Rights associated with the Common Shares of the Company
represented thereby. In the event that the Company purchases or acquires any
Common Shares of the Company after the Record Date but prior to the Distribution
Date, any Rights associated with such Common Shares of the Company shall be
deemed cancelled and retired so that the Company shall not be entitled to
exercise any Rights associated with the Common Shares of the Company which are
no longer outstanding.

                  Section 4. Form of Right Certificates. The Right Certificates
(and the forms of election to purchase Preferred Shares and of assignment to be
printed on the reverse thereof) shall be substantially the same as Exhibit B
hereto, and may have such marks of identification or designation and such
legends, summaries or endorsements printed thereon as the Company may 


                                      -9-
<PAGE>

deem appropriate (which do not unreasonably affect the duties or
responsibilities of the Rights Agent) 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 applicable rule or regulation made pursuant thereto
or with any applicable rule or regulation of any stock exchange or the National
Association of Securities Dealers, Inc., or to conform to usage. Subject to the
provisions of Section 22 hereof, the Right Certificates shall entitle the
holders thereof to purchase such number of one one-thousandths of a Preferred
Share as shall be set forth therein at the price per one one-thousandth of a
Preferred Share set forth therein (the "Purchase Price"), but the number of such
one one-thousandths of a Preferred Share and the Purchase Price shall be subject
to adjustment as provided herein.

                  Section 5. Countersignature and Registration. The Right
Certificates shall be executed on behalf of the Company by its Chairman of the
Board, its Chief Executive Officer, its President or any Vice President, either
manually or by facsimile signature, shall have affixed thereto the Company's
seal or a facsimile thereof, and shall be attested by the Secretary or an
Assistant Secretary of the Company, either manually or by facsimile signature.
The Right Certificates shall be manually countersigned by the Rights Agent and
shall not be valid for any purpose unless countersigned. In case any officer of
the Company who shall have signed any of the Right Certificates shall cease to
be such officer of the Company before countersignature by the Rights Agent and
issuance and delivery by the Company, such Right 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 individual who signed such Right
Certificates had not ceased to be such officer of the Company; and any Right
Certificate may be signed on behalf of the Company by 


                                      -10-
<PAGE>

any individual who, at the actual date of the execution of such Right
Certificate, shall be a proper officer of the Company to sign such Right
Certificate, although at the date of the execution of this Agreement any such
individual was not such an officer.

                  Following the Distribution Date, the Rights Agent will keep or
cause to be kept, at its Designated Office, books for registration and transfer
of the Right Certificates issued hereunder. Such books shall show the names and
addresses of the respective holders of the Right Certificates, the number of
Rights evidenced on its face by each of the Right Certificates and the date of
each of the Right Certificates.

                  Section 6. Transfer, Split Up, Combination and Exchange of
Right Certificates; Mutilated, Destroyed, Lost or Stolen Right Certificates.
Subject to the provisions of Section 14 hereof, at any time after the Close of
Business on the Distribution Date, and at or prior to the Close of Business on
the earlier of the Redemption Date or the Final Expiration Date, any Right
Certificate or Right Certificates (other than Right Certificates representing
Rights that have become void pursuant to Section 11(a)(ii) hereof or that have
been exchanged pursuant to Section 24 hereof) may be transferred, split up,
combined or exchanged for another Right Certificate or Right Certificates
entitling the registered holder to purchase a like number of one one-thousandths
of a Preferred Share as the Right Certificate or Right Certificates surrendered
then entitled such holder to purchase. Any registered holder desiring to
transfer, split up, combine or exchange any Right Certificate or Right
Certificates shall make such request in writing delivered to the Rights Agent,
and shall surrender the Right Certificate or Right Certificates to be
transferred, split up, combined or exchanged at the Designated Office of the
Rights Agent. Thereupon the Rights Agent shall countersign and deliver to the
Person entitled thereto a Right


                                      -11-
<PAGE>

Certificate or Right Certificates, as the case may be, as so requested. The
Company may require payment 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 Right Certificates.

                  Upon receipt by the Company and the Rights Agent of evidence
reasonably satisfactory to them of the loss, theft, destruction or mutilation of
a Right Certificate, and, in case of loss, theft or destruction, of indemnity or
security reasonably satisfactory to them, and, at the Company's request,
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 Right Certificate if mutilated, the Company will make and deliver a new
Right Certificate of like tenor to the Rights Agent for delivery to the
registered holder in lieu of the Right Certificate so lost, stolen, destroyed or
mutilated.

                  Section 7. Exercise of Rights; Purchase Price; Expiration Date
of Rights. (a) The registered holder of any Right Certificate may exercise the
Rights evidenced thereby (except as otherwise provided herein), in whole or in
part, at any time after the Distribution Date, upon surrender of the Right
Certificate, with the form of election to purchase on the reverse side thereof
duly executed, to the Rights Agent at the Designated Office of the Rights Agent,
together with payment of the Purchase Price for each one one-thousandth of a
Preferred Share as to which the Rights are exercised, at or prior to the
earliest of (i) the Close of Business on November 10, 2008 (the "Final
Expiration Date"), (ii) the time at which the Rights are redeemed as provided in
Section 23 hereof (the "Redemption Date"), or (iii) the time at which such
Rights are exchanged as provided in Section 24 hereof.

                                      -12-
<PAGE>

                  (b) The Purchase Price for each one one-thousandth of a
Preferred Share purchasable pursuant to the exercise of a Right shall initially
be $175, and shall be subject to adjustment from time to time as provided in
Section 11 or 13 hereof, and shall be payable in lawful money of the United
States of America in accordance with paragraph (c) below.

                  (c) Upon receipt of a Right Certificate representing
exercisable Rights, with the form of election to purchase duly executed,
accompanied by payment of the Purchase Price for the shares to be purchased and
an amount equal to any applicable transfer tax required to be paid by the holder
of such Right Certificate in accordance with Section 9 hereof by certified
check, cashier's check or money order payable to the order of the Company, the
Rights Agent shall thereupon promptly (i) (A) requisition from any transfer
agent of the Preferred Shares certificates for the number of Preferred Shares to
be purchased and the Company hereby irrevocably authorizes any such transfer
agent to comply with all such requests, or (B) requisition from the depositary
agent depositary receipts representing such number of one one-thousandths of a
Preferred Share as are to be purchased (in which case certificates for the
Preferred Shares represented by such receipts shall be deposited by the transfer
agent of the Preferred Shares with such depositary agent) and the Company hereby
directs such depositary agent to comply with such request; (ii) when
appropriate, requisition from the Company the amount of cash to be paid in lieu
of issuance of fractional shares in accordance with Section 14 hereof; (iii)
promptly 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 Right
Certificate, registered in such name or names as may be designated by such
holder; and (iv) when appropriate, after receipt, promptly deliver such cash to
or upon the order of the registered holder of such Right Certificate.

                                      -13-
<PAGE>

                  (d) In case the registered holder of any Right Certificate
shall exercise less than all the Rights evidenced thereby, a new Right
Certificate evidencing Rights equivalent to the Rights remaining unexercised
shall be issued by the Rights Agent to registered holder of such Right
Certificate or to such holder's duly authorized assigns, subject to the
provisions of Section 14 hereof.

                  Section 8. Cancellation and Destruction of Right Certificates.
All Right Certificates surrendered for the purpose of exercise, transfer, split
up, combination or exchange shall, if surrendered to the Company or to any of
its agents, be delivered to the Rights Agent for cancellation or in cancelled
form, or, if surrendered to the Rights Agent, shall be cancelled by it, and no
Right 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 Right Certificate purchased or acquired by the
Company otherwise than upon the exercise thereof. The Rights Agent shall deliver
all cancelled Right Certificates to the Company, or shall, at the written
request of the Company, destroy such cancelled Right Certificates, and, in such
case, shall deliver a certificate of destruction thereof to the Company.

                  Section 9. Availability of Preferred Shares. The Company
covenants and agrees that it will cause to be reserved and kept available out of
its authorized and unissued Preferred Shares or any Preferred Shares held in its
treasury the number of Preferred Shares that will be sufficient to permit the
exercise in full of all outstanding Rights in accordance with Section 7 hereof.
The Company covenants and agrees that it will take all such action as may be
necessary to ensure that all Preferred Shares delivered upon exercise of Rights
shall, at the time of delivery 


                                      -14-
<PAGE>

of the certificates for such Preferred Shares (subject to payment of the
Purchase Price), be duly and validly authorized and issued and fully paid and
nonassessable shares.

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

                  Section 10. Preferred Shares Record Date. Each Person in whose
name any certificate for Preferred Shares is issued upon the exercise of Rights
shall for all purposes be deemed to have become the holder of record of the
Preferred Shares represented thereby on, and such certificate shall be dated,
the date upon which the Right Certificate evidencing such Rights was duly
surrendered and payment of the Purchase Price (and any applicable transfer
taxes) was made; provided, however, that, if the date of such surrender and
payment is a date upon which the Preferred Shares transfer books of the Company
are closed, such Person shall be deemed to have become the record holder of such
shares on, and such certificate shall be dated, the next succeeding Business Day
on which the Preferred Shares transfer books of the Company are open. 


                                      -15-
<PAGE>

Prior to the exercise of the Rights evidenced thereby, the holder of a Right
Certificate shall not be entitled to any rights of a holder of Preferred 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 of Shares or
Number of Rights. The Purchase Price, the number of Preferred Shares covered by
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
date of this Agreement (A) declare a dividend on the Preferred Shares payable in
Preferred Shares, (B) subdivide the outstanding Preferred Shares, (C) combine
the outstanding Preferred Shares into a smaller number of Preferred Shares or
(D) issue any shares of its capital stock in a reclassification of the Preferred
Shares (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), 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 capital stock issuable on such date, shall be proportionately adjusted
so that the holder of any Right exercised after such time shall be entitled to
receive the aggregate number and kind of shares of capital stock which, if such
Right had been exercised immediately prior to such date and at a time when the
Preferred Shares transfer books of the Company were open, such holder would have
owned upon such exercise and been entitled to re-


                                      -16-
<PAGE>

ceive by virtue of such dividend, subdivision, combination or reclassification;
provided, however, that in no event shall the consideration to be paid upon the
exercise of one Right be less than the aggregate par value of the shares of
capital stock of the Company issuable upon exercise of one Right.

                  (ii) Subject to Section 24 hereof, in the event any Person
becomes an Acquiring Person, each holder of a Right shall thereafter have a
right to receive, upon exercise thereof at a price equal to the then current
Purchase Price multiplied by the number of one one-thousandths of a Preferred
Share for which a Right is then exercisable, in accordance with the terms of
this Agreement and in lieu of Preferred Shares, such number of Common Shares of
the Company as shall equal the result obtained by (A) multiplying the then
current Purchase Price by the number of one one-thousandths of a Preferred Share
for which a Right is then exercisable and dividing that product by (B) 50% of
the then current per share market price of the Common Shares of the Company
(determined pursuant to Section 11(d) hereof) on the date of the occurrence of
such event. In the event that any Person shall become an Acquiring Person and
the Rights shall then be outstanding, the Company shall not take any action
which would eliminate or diminish the benefits intended to be afforded by the
Rights.

                  From and after the occurrence of such event, any Rights that
are or were acquired or beneficially owned by any Acquiring Person (or any
Associate or Affiliate of such Acquiring Person) shall be void, and any holder
of such Rights shall thereafter have no right to exercise such Rights under any
provision of this Agreement. No Right Certificate shall be issued pursuant to
Section 3 hereof that represents Rights beneficially owned by an Acquiring
Person whose Rights would be void pursuant to the preceding sentence or any
Associate or Affiliate thereof; no 


                                      -17-
<PAGE>

Right Certificate shall be issued at any time upon the transfer of any Rights to
an Acquiring Person whose Rights would be void pursuant to the preceding
sentence or any Associate or Affiliate thereof or to any nominee of such
Acquiring Person, Associate or Affiliate; and any Right Certificate delivered to
the Rights Agent for transfer to an Acquiring Person whose Rights would be void
pursuant to the preceding sentence shall be cancelled.

                  (iii) In the event that there shall not be sufficient Common
Shares issued but not outstanding or authorized but unissued to permit the
exercise in full of the Rights in accordance with subparagraph (ii) above, the
Company shall take all such action as may be necessary to authorize additional
Common Shares for issuance upon exercise of the Rights. In the event the Company
shall, after good faith effort, be unable to take all such action as may be
necessary to authorize such additional Common Shares, the Company shall
substitute, for each Common Share that would otherwise be issuable upon exercise
of a Right, a number of Preferred Shares or fraction thereof such that the
current per share market price of one Preferred Share multiplied by such number
or fraction is equal to the current per share market price of one Common Share
as of the date of issuance of such Preferred Shares or fraction thereof.

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


                                      -18-
<PAGE>

per share market price of the Preferred Shares (as defined in Section 11(d)) on
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 Preferred Shares outstanding on such record date plus the number of
Preferred Shares which the aggregate offering price of the total number of
Preferred Shares and/or equivalent preferred shares 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 Preferred Shares outstanding on such record date
plus the number of additional Preferred Shares and/or equivalent preferred
shares to be offered for subscription or purchase (or into which the convertible
securities so to be offered are initially convertible); provided, however, that
in no event shall the consideration to be paid upon the exercise of one Right be
less than the aggregate par value of the shares of capital stock of the Company
issuable upon exercise of one Right. In case such subscription price may be paid
in a consideration part or all of which shall 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 holders
of the Rights. Preferred Shares 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, options or warrants are not so issued, the
Purchase Price shall be adjusted to be the Purchase Price which would then be in
effect if such record date had not been fixed.

                                      -19-
<PAGE>

                  (c) In case the Company shall fix a record date for the making
of a distribution to all holders of the Preferred Shares (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
or assets (other than a regular quarterly cash dividend or a dividend payable in
Preferred Shares) 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 then current per share market price of the Preferred Shares 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
and holders of the Rights) of the portion of the assets or evidences of
indebtedness so to be distributed or of such subscription rights or warrants
applicable to one Preferred Share and the denominator of which shall be such
then-current per share market price of the Preferred Shares; provided, however,
that in no event shall the consideration to be paid upon the exercise of one
Right be less than the aggregate par value of the shares of capital stock of the
Company to be issued upon exercise of one Right. 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 again be adjusted to be
the Purchase Price which would then be in effect if such record date had not
been fixed.

                  (d) (i) For the purpose of any computation hereunder, the
"current per share market price" of any security (a "Security" for the purpose
of this Section 11(d)(i)) on any date shall be deemed to be the average of the
daily closing prices per share of such Security for the 30 


                                      -20-
<PAGE>

consecutive Trading Days immediately prior to such date; provided, however,
that, in the event that the current per share market price of the Security is
determined during a period following the announcement by the issuer of such
Security of (A) a dividend or distribution on such Security payable in shares of
such Security or Securities convertible into such shares, or (B) any
subdivision, combination or reclassification of such Security and prior to the
expiration of 30 Trading Days after the ex-dividend date for such dividend or
distribution, or the record date for such subdivision, combination or
reclassification, then, and in each such case, the current per share market
price shall be appropriately adjusted to reflect the current market price per
share equivalent of such Security. The closing price for each day shall be the
last sale 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 Security is not listed or admitted to trading on the New York Stock
Exchange, as reported in the principal consolidated transaction reporting system
with respect to securities listed on the principal national securities exchange
on which the Security is listed or admitted to trading or, if the Security is
not listed or admitted to trading on any national securities exchange, the last
quoted 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 NASDAQ or such other
system then in use, or, if on any such date the Security is not quoted by any
such organization, the average of the closing bid and asked prices as furnished
by a professional market maker making a market in the Security selected by the
Board of Directors of the Company. The term "Trading Day" shall mean a day on
which the principal national securities exchange on which the Security is listed
or admitted to trading is open for the 


                                      -21-
<PAGE>

transaction of business, or, if the Security is not listed or admitted to
trading on any national securities exchange, a Business Day.

                  (ii) For the purpose of any computation hereunder, the
"current per share market price" of the Preferred Shares shall be determined in
accordance with the method set forth in Section 11(d)(i). If the Preferred
Shares are not publicly traded, the "current per share market price" of the
Preferred Shares shall be conclusively deemed to be the current per share market
price of the Common Shares as determined pursuant to Section 11(d)(i) hereof
(appropriately adjusted to reflect any stock split, stock dividend or similar
transaction occurring after the date hereof), multiplied by one hundred. If
neither the Common Shares nor the Preferred Shares are publicly held or so
listed or traded, "current per share market price" 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.

                  (e) 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 which 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 one one-millionth
of a Preferred Share or one ten-thousandth of any other share or security 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 requires such
adjustment or (ii) the date of the expiration of the right to exercise any
Rights.

<PAGE>

                  (f) If, as a result of an adjustment made pursuant to Section
11(a) hereof, the holder of any Right thereafter exercised shall become entitled
to receive any shares of capital stock of the Company other than Preferred
Shares, thereafter the number of such other shares so receivable upon exercise
of any Right 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 Shares contained in Section 11(a) through (c) hereof, inclusive, and
the provisions of Sections 7, 9, 10 and 13 hereof with respect to the Preferred
Shares 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 one one-thousandths of a
Preferred Share 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
one one-thousandths of a Preferred Share (calculated to the nearest one
one-millionth of a Preferred Share) obtained by (A) multiplying (x) the number
of one one-thousandths of a share 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 (B) dividing the product so obtained by the
Purchase Price in effect immediately after such adjustment of the Purchase
Price.

                                      -23-
<PAGE>

                  (i) The Company may elect, on or after the date of any
adjustment of the Purchase Price, to adjust the number of Rights in substitution
for any adjustment in the number of one one-thousandths of a Preferred Share
purchasable upon the exercise of a Right. Each of the Rights outstanding after
such adjustment of the number of Rights shall be exercisable for the number of
one one-thousandths of a Preferred Share 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 one 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 (with subsequent prompt notice thereof to the Rights Agent), 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 Right Certificates have
been issued, shall be at least 10 days later than the date of the public
announcement. If Right 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 Right
Certificates on such record date Right 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
Right Certificates held by such holders prior to the date of adjustment, and
upon surrender thereof, if required by the Company, new Right Certificates
evidencing all the Rights to which such holders shall be entitled after such
adjustment. Right Certificates so to be distributed shall be issued, executed
and countersigned in the manner 


                                      -24-
<PAGE>

provided for herein, and shall be registered in the names of the holders of
record of Right Certificates on the record date specified in the public
announcement.

                  (j) Irrespective of any adjustment or change in the Purchase
Price or in the number of one one-thousandths of a Preferred Share issuable upon
the exercise of the Rights, the Right Certificates theretofore and thereafter
issued may continue to express the Purchase Price and the number of one
one-thousandths of a Preferred Share which were expressed in the initial Right
Certificates issued hereunder.

                  (k) Before taking any action that would cause an adjustment
reducing the Purchase Price below one one-thousandth of the then par value, if
any, of the Preferred Shares issuable upon exercise of the Rights, the Company
shall take any corporate action which may, in the opinion of its counsel, be
necessary in order that the Company may validly and legally issue fully paid and
nonassessable Preferred Shares 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 issuing to the holder of any Right exercised after such record date of
the Preferred Shares and other capital stock or securities of the Company, if
any, issuable upon such exercise over and above the Preferred Shares 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 (i) subsequently provide the Rights Agent with
prompt notice of such election, and (ii) deliver to such 


                                      -25-
<PAGE>

holder a due bill or other appropriate instrument evidencing such holder's right
to receive such additional shares 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 it, in its sole discretion, shall
determine to be advisable in order that any consolidation or subdivision of the
Preferred Shares, issuance wholly for cash of any Preferred Shares at less than
the current market price, issuance wholly for cash of Preferred Shares or
securities which by their terms are convertible into or exchangeable for
Preferred Shares, dividends on Preferred Shares payable in Preferred Shares or
issuance of rights, options or warrants referred to in Section 11(b) hereof,
hereafter made by the Company to holders of the Preferred Shares shall not be
taxable to such stockholders.

                  (n) In the event that, at any time after the date of this
Agreement and prior to the Distribution Date, the Company shall (i) declare or
pay any dividend on the Common Shares payable in Common Shares, or (ii) effect a
subdivision, combination or consolidation of the Common Shares (by
reclassification or otherwise than by payment of dividends in Common Shares)
into a greater or lesser number of Common Shares, then, in any such case, (A)
the number of one one-thousandths of a Preferred Share purchasable after such
event upon proper exercise of each Right shall be determined by multiplying the
number of one one-thousandths of a Preferred Share so purchasable immediately
prior to such event by a fraction, the numerator of which is the number of
Common Shares outstanding immediately before such event and the denominator of
which is the number of Common Shares outstanding immediately after such event,
and (B) each Common Share outstanding immediately after such event shall have
issued with 


                                      -26-
<PAGE>

respect to it that number of Rights which each Common Share outstanding
immediately prior to such event had issued with respect to it. The adjustments
provided for in this Section 11(n) shall be made successively whenever such a
dividend is declared or paid or such a subdivision, combination or consolidation
is effected.

                  Section 12. Certificate of Adjusted Purchase Price or Number
of Shares. Whenever an adjustment is made as provided in Section 11 or 13
hereof, the Company shall promptly (a) prepare a certificate setting forth such
adjustment and a brief statement of the facts accounting for such adjustment,
(b) file with the Rights Agent and with each transfer agent for the Common
Shares or the Preferred Shares and the Securities and Exchange Commission a copy
of such certificate and (c) if such adjustment occurs at any time after the
Distribution Date, mail a brief summary thereof to each holder of a Right
Certificate in accordance with Section 25 hereof. The Rights Agent shall be
fully protected in relying on any such certificate and on any adjustment
therein.

                  Section 13. Consolidation, Merger or Sale or Transfer of
Assets or Earning Power. In the event, directly or indirectly, at any time after
a Person has become an Acquiring Person, (a) the Company shall consolidate with,
or merge with and into, any other Person, (b) any Person shall consolidate with
the Company, or merge with and into the Company and the Company shall be the
continuing or surviving corporation of such merger and, in connection with such
merger, all or part of the Common Shares shall be changed into or exchanged for
stock or other securities of any other Person (or the Company) or cash or any
other property, or (c) the Company shall sell or otherwise transfer (or one or
more of its Subsidiaries shall sell or otherwise transfer), in one or more
transactions, assets or earning power aggregating 50% or more of 


                                      -27-
<PAGE>

the assets or earning power of the Company and its Subsidiaries (taken as a
whole) to any other Person other than the Company or one or more of its
wholly-owned Subsidiaries, then, and in each such case, proper provision shall
be made so that (i) each holder of a Right (except as otherwise provided herein)
shall thereafter have the right to receive, upon the exercise thereof at a price
equal to the then current Purchase Price multiplied by the number of one
one-thousandths of a Preferred Share for which a Right is then exercisable, in
accordance with the terms of this Agreement and in lieu of Preferred Shares,
such number of Common Shares of such other Person (including the Company as
successor thereto or as the surviving corporation) as shall equal the result
obtained by (A) multiplying the then current Purchase Price by the number of one
one-thousandths of a Preferred Share for which a Right is then exercisable and
dividing that product by (B) 50% of the then current per share market price of
the Common Shares of such other Person (determined pursuant to Section 11(d)
hereof) on the date of consummation of such consolidation, merger, sale or
transfer; (ii) the issuer of such Common Shares shall thereafter be liable for,
and shall assume, by virtue of such consolidation, merger, sale or transfer, all
the obligations and duties of the Company pursuant to this Agreement; (iii) the
term "Company" shall thereafter be deemed to refer to such issuer; and (iv) such
issuer shall take such steps (including, but not limited to, the reservation of
a sufficient number of its Common Shares in accordance with Section 9 hereof) in
connection with such consummation as may be necessary to assure that the
provisions hereof shall thereafter be applicable, as nearly as reasonably may
be, in relation to the Common Shares of the Company thereafter deliverable upon
the exercise of the Rights. The Company shall not consummate any such
consolidation, merger, sale or transfer unless, prior thereto, the Company and
such issuer shall have executed and delivered to the Rights Agent a supplemental
agreement so providing. The Company shall not enter into any transaction of the

                                      -28-
<PAGE>

kind referred to in this Section 13 if at the time of such transaction there are
any rights, warrants, instruments or securities outstanding or any agreements or
arrangements which, as a result of the consummation of such transaction, would
eliminate or substantially diminish the benefits intended to be afforded by the
Rights. The provisions of this Section 13 shall similarly apply to successive
mergers or consolidations or sales or other transfers.

                  Section 14. Fractional Rights and Fractional Shares. (a) The
Company shall not be required to issue fractions of Rights or to distribute
Right Certificates which evidence fractional Rights. In lieu of such fractional
Rights, there shall be paid to the registered holders of the Right Certificates
with regard to which such fractional Rights would otherwise be issuable, an
amount in cash equal to the same fraction of the current market value of a whole
Right. For the purposes of this Section 14(a), the current market value of a
whole Right shall be the closing price of the Rights for the Trading Day
immediately prior to the date on which such fractional Rights would have been
otherwise issuable. The closing price for any day shall be the last sale 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 Rights are not listed or admitted to trading on the New York Stock Exchange,
as reported in the principal consolidated transaction reporting system with
respect to securities listed on the principal national securities exchange on
which the Rights are listed or admitted to trading or, if the Rights are not
listed or admitted to trading on any national securities exchange, the last
quoted 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 NASDAQ or such other
system then in use or, if on any 


                                      -29-
<PAGE>

such date the Rights are not quoted by any such organization, the average of the
closing bid and asked prices as furnished by a professional market maker making
a market in the Rights selected by the Board of Directors of the Company. If on
any such date no such market maker is making a market in the Rights, the fair
value of the Rights on such date as determined in good faith by the Board of
Directors of the Company shall be used.

                  (b) The Company shall not be required to issue fractions of
Preferred Shares (other than fractions which are integral multiples of one
one-thousandth of a Preferred Share) upon exercise of the Rights or to
distribute certificates which evidence fractional Preferred Shares (other than
fractions which are integral multiples of one one-thousandth of a Preferred
Share). Fractions of Preferred Shares in integral multiples of one
one-thousandth of a Preferred Share may, at the election of the Company, 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 Preferred Shares represented by such depositary receipts. In lieu of
fractional Preferred Shares that are not integral multiples of one
one-thousandth of a Preferred Share, the Company shall pay to the registered
holders of Right Certificates at the time such Rights are exercised as herein
provided an amount in cash equal to the same fraction of the current market
value of one Preferred Share. For the purposes of this Section 14(b), the
current market value of a Preferred Share shall be the closing price of a
Preferred Share (as determined pursuant to the second sentence of Section
11(d)(i) hereof) for the Trading Day immediately prior to the date of such
exercise.

                                      -30-
<PAGE>

                  (c) The holder of a Right, by the acceptance of the Right,
expressly waives such holder's right to receive any fractional Rights or any
fractional shares upon exercise of a Right (except as provided above).

                  Section 15. Rights of Action. All rights of action in respect
of this Agreement, excepting the rights of action given to the Rights Agent
under Section 18 hereof, are vested in the respective registered holders of the
Right Certificates (and, prior to the Distribution Date, the registered holders
of the Common Shares); and any registered holder of any Right Certificate (or,
prior to the Distribution Date, of the Common Shares), without the consent of
the Rights Agent or of the holder of any other Right Certificate (or, prior to
the Distribution Date, of the Common Shares), may, in such holder's own behalf
and for such holder's own benefit, enforce, and may institute and maintain any
suit, action or proceeding against the Company to enforce, or otherwise act in
respect of, such holder's right to exercise the Rights evidenced by such Right
Certificate in the manner provided in such Right 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
will be entitled to specific performance of the obligations under, and
injunctive relief against actual or threatened violations of the obligations of
any Person subject to, this Agreement.

                  Section 16. Agreement of Right 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:

                                      -31-
<PAGE>

                  (a) prior to the Distribution Date, the Rights will be
transferable only in connection with the transfer of the Common Shares;

                  (b) after the Distribution Date, the Right Certificates are
transferable only on the registry books of the Rights Agent if surrendered at
the Designated Office of the Rights Agent, duly endorsed or accompanied by a
proper instrument of transfer; and

                  (c) the Company and the Rights Agent may deem and treat the
Person in whose name the Right Certificate (or, prior to the Distribution Date,
the associated Common Shares certificate) is registered as the absolute owner
thereof and of the Rights evidenced thereby (notwithstanding any notations of
ownership or writing on the Right Certificate or the associated Common Shares
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.

                  Section 17. Right Certificate Holder Not Deemed a Stockholder.
No holder, as such, of any Right Certificate shall be entitled to vote, receive
dividends or be deemed for any purpose the holder of the Preferred Shares or any
other securities of the Company which may at any time be issuable on the
exercise of the Rights represented thereby, nor shall anything contained herein
or in any Right Certificate be construed to confer upon the holder of any Right
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 sub-


                                      -32-
<PAGE>

scription rights, or otherwise, until the Right or Rights evidenced by such
Right Certificate shall have been exercised in accordance with the provisions
hereof.

                  Section 18. Concerning the Rights Agent. 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 other disbursements incurred in the preparation,
delivery, amendment, 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. In no case will the Rights Agent be liable for
special, indirect, incidental or consequential loss or damage arising in
connection with the acceptance and administration of this agreement.

                  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 Right
Certificate or certificate for the Preferred Shares or Common Shares 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 to be genuine
and to be signed, executed and, where necessary, verified or acknowledged, by
the proper person or persons, or otherwise upon the advice of counsel as set
forth in Section 20 hereof.

                  Section 19. Merger or Consolidation or Change of Name of
Rights Agent. Any Person into which the Rights Agent or any successor Rights
Agent may be merged or with which it may be consolidated, or any Person
resulting from any merger or consolidation to which the Rights Agent or any
successor Rights Agent shall be a party, or any Person succeeding to the
shareholder services 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 that such Person 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 Right Certificates shall have been countersigned but not
delivered, any such successor Rights Agent may adopt the countersignature of the
predecessor Rights Agent and deliver such Right Certificates so countersigned;
and, in case at that time any of the Right Certificates shall not have been
countersigned, any successor Rights Agent may countersign such Right
Certificates either in the name of the predecessor Rights Agent or in the name
of the successor Rights Agent; and, in all such cases, such Right Certificates
shall have the full force provided in the Right Certificates and in this
Agreement.

                  In case at any time the name of the Rights Agent shall be
changed and at such time any of the Right Certificates shall have been
countersigned but not delivered, the Rights Agent may adopt the countersignature
under its prior name and deliver Right Certificates so countersigned; and, in
case at that time any of the Right Certificates shall not have been
countersigned, the Rights Agent may countersign such Right Certificates either
in its prior name or in its 


                                      -34-
<PAGE>

changed name; and, in all such cases, such Right Certificates shall have the
full force provided in the Right Certificates and in this Agreement.

                  Section 20. Duties of Rights Agent. The Rights Agent
undertakes the duties and obligations expressly imposed by this Agreement upon
the following terms and conditions, by all of which the Company and the holders
of Right 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 oral or written 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 oral or written 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 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 any one of the Chairman of the Board, the
Chief Executive Officer, 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 to the Company
and any other Person only for its own gross negligence, bad faith or willful
misconduct.

                                      -35-
<PAGE>

                  (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
Right Certificates (except its countersignature thereof) or be required to
verify the same, 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 Right 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 Right Certificate;
nor shall it be responsible for any change in the exercisability of the Rights
(including the Rights becoming void pursuant to Section 11(a)(ii) hereof) or any
adjustment in the terms of the Rights (including the manner, method or amount
thereof) provided for in Section 3, 11, 13, 23 or 24 hereof, or the ascertaining
of the existence of facts that would require any such change or adjustment
(except with respect to the exercise of Rights evidenced by Right Certificates
after actual notice that such change or adjustment is required); nor shall it by
any act hereunder be deemed to make any representation or warranty as to the
authorization or reservation of any Preferred Shares to be issued pursuant to
this Agreement or any Right Certificate or as to whether any Preferred Shares
will, when issued, be validly authorized and issued, fully paid and
nonassessable.

                  (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
any one of the Chairman of the Board, the Chief Executive Officer, 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 by it in good faith in accordance
with instructions of any such officer or for any delay in acting while waiting
for those instructions.

                  (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, default, neglect or misconduct of any
such attorneys or agents or for any loss to the Company resulting from any such
act, default, neglect or misconduct, provided 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 


                                      -37-
<PAGE>

hereunder or in the exercise of its rights if it reasonably believes that
repayment of such funds or adequate indemnification against such risk is not
reasonably assured to it.

                  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 Shares or Preferred Shares by registered or
certified mail, and to the holders of the Right Certificates by first-class
mail. The Company may remove the Rights Agent or any successor Rights Agent 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 Shares or
Preferred Shares by registered or certified mail, and to the holders of the
Right Certificates by first-class mail. If the Rights Agent shall resign or be
removed or shall otherwise become incapable of acting, the Company shall appoint
a successor to the Rights Agent. 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 holder of a Right Certificate
(which holder shall, with such notice, submit such holder's Right Certificate
for inspection by the Company), then the registered holder of any Right
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 Person 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 Person is authorized to do business in the
State of New York), in good standing, having an office in the State of New York,
which is subject to supervision or examination by federal or state authority and
which has at the 


                                      -38-
<PAGE>

time of its appointment as Rights Agent a combined capital and surplus of at
least $50 million. 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 Shares or Preferred Shares, and mail a notice thereof in writing to
the registered holders of the Right 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 Right Certificates.
Notwithstanding any of the provisions of this Agreement or of the Rights to the
contrary, the Company may, at its option, issue new Right Certificates
evidencing Rights in such form as may be approved by the Board of Directors of
the Company 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 Right Certificates made in accordance with the provisions of this
Agreement.

                  Section 23. Redemption. (a) The Board of Directors of the
Company may, at its option, at any time prior to such time as any Person becomes
an Acquiring Person, redeem all but not less than all the then outstanding
Rights at a redemption price of $.01 per Right, appropriately adjusted to
reflect any stock split, stock dividend or similar transaction occurring after

                                      -39-
<PAGE>

the date hereof (such redemption price being hereinafter referred to as the
"Redemption Price"). The redemption of the Rights by the Board of Directors of
the Company may be made effective at such time, on such basis and with such
conditions as the Board of Directors of the Company, in its sole discretion, may
establish.

                  (b) Immediately upon the action of the Board of Directors of
the Company ordering the redemption of the Rights pursuant to paragraph (a) of
this Section 23, 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. The Company shall
promptly give public notice of any such redemption (with subsequent prompt
notice thereof to the Rights Agent); provided, however, that the failure to
give, or any defect in, any such notice shall not affect the validity of such
redemption. Within 10 days after such action of the Board of Directors of the
Company ordering the redemption of the Rights, the Company shall mail a notice
of redemption to all the holders of the then outstanding Rights at their last
addresses as they appear upon the registry books of the Rights Agent or, prior
to the Distribution Date, on the registry books of the transfer agent for the
Common Shares. 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
redemption will state the method by which the payment of the Redemption Price
will be made. Neither the Company nor any of its Affiliates or Associates may
redeem, acquire or purchase for value any Rights at any time in any manner other
than that specifically set forth in this Section 23 or in Section 24 hereof, and
other than in connection with the purchase of Common Shares prior to the
Distribution Date.

<PAGE>

                  Section 24. Exchange. (a) The Board of Directors of the
Company may, at its option, at any time after any Person becomes an Acquiring
Person, 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 11(a)(ii) hereof) for Common Shares at an exchange ratio of one
Common Share per Right, appropriately adjusted to reflect any adjustment in the
number of Rights pursuant to Section 11(i) (such exchange ratio being
hereinafter referred to as the "Exchange Ratio"). Notwithstanding the foregoing,
the Board of Directors of the Company shall not be empowered to effect such
exchange at any time after any Person (other than the Company, any Subsidiary of
the Company, any employee benefit plan of the Company or any such Subsidiary, or
any entity holding Common Shares for or pursuant to the terms of any such plan),
together with all Affiliates and Associates of such Person, becomes the
Beneficial Owner of 50% or more of the Common Shares then outstanding.

                  (b) Immediately upon the action of the Board of Directors of
the Company ordering the exchange of any Rights pursuant to paragraph (a) of
this Section 24 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 Common Shares equal to
the number of such Rights held by such holder multiplied by the Exchange Ratio.
The Company shall promptly give public notice (with subsequent prompt notice
thereof to the Rights Agent) 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 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

                                      -41-
<PAGE>

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 Common Shares for Rights will be effected, and, in the event of any
partial exchange, the number of Rights which will be exchanged. Any partial
exchange shall be effected pro rata based on the number of Rights (other than
Rights which have become void pursuant to the provisions of Section 11(a)(ii)
hereof) held by each holder of Rights.

                  (c) In the event that there shall not be sufficient Common
Shares issued but not outstanding or authorized but unissued to permit any
exchange of Rights as contemplated in accordance with this Section 24, the
Company shall take all such action as may be necessary to authorize additional
Common Shares for issuance upon exchange of the Rights. In the event the Company
shall, after good faith effort, be unable to take all such action as may be
necessary to authorize such additional Common Shares, the Company shall
substitute, for each Common Share that would otherwise be issuable upon exchange
of a Right, a number of Preferred Shares or fraction thereof such that the
current per share market price of one Preferred Share multiplied by such number
or fraction is equal to the current per share market price of one Common Share
as of the date of issuance of such Preferred Shares or fraction thereof.

                  (d) The Company shall not be required to issue fractions of
Common Shares or to distribute certificates which evidence fractional Common
Shares. In lieu of such fractional Common Shares, the Company shall pay to the
registered holders of the Right Certificates with regard to which such
fractional Common Shares would otherwise be issuable an amount in cash equal to
the same fraction of the current market value of a whole Common Share. For the
purposes of this paragraph (d), the current market value of a whole Common Share
shall be the 


                                      -42-
<PAGE>

closing price of a Common Share (as determined pursuant to the second sentence
of Section 11(d)(i) hereof) for the Trading Day immediately prior to the date of
exchange pursuant to this Section 24.

                  Section 25. Notice of Certain Events. (a) In case the Company
shall, at any time after the Distribution Date, propose (i) to pay any dividend
payable in stock of any class to the holders of the Preferred Shares or to make
any other distribution to the holders of the Preferred Shares (other than a
regular quarterly cash dividend), (ii) to offer to the holders of the Preferred
Shares rights or warrants to subscribe for or to purchase any additional
Preferred Shares or shares of stock of any class or any other securities, rights
or options, (iii) to effect any reclassification of the Preferred Shares (other
than a reclassification involving only the subdivision of outstanding Preferred
Shares), (iv) to effect any consolidation or merger into or with, or to effect
any sale or other transfer (or to permit one or more of its Subsidiaries to
effect any sale or other transfer), in one or more transactions, of 50% or more
of the assets or earning power of the Company and its Subsidiaries (taken as a
whole) to, any other Person, (v) to effect the liquidation, dissolution or
winding up of the Company, or (vi) to declare or pay any dividend on the Common
Shares payable in Common Shares or to effect a subdivision, combination or
consolidation of the Common Shares (by reclassification or otherwise than by
payment of dividends in Common Shares), then, in each such case, the Company
shall give to each holder of a Right Certificate, 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, or distribution of rights or warrants,
or the date on which such reclassification, consolidation, merger, sale,
transfer, liquidation, dissolution, or winding up is to take place and the date
of participation therein by the holders of the 


                                      -43-
<PAGE>

Common Shares and/or Preferred Shares, if any such date is to be fixed, and such
notice shall be so given.

                  (b) In case the event set forth in Section 11(a)(ii) hereof
shall occur, then the Company shall, as soon as practicable thereafter, give to
each holder of a Right Certificate, in accordance with Section 26 hereof, a
notice of the occurrence of such event, which notice shall describe such event
and the consequences of such event to holders of Rights under Section 11(a)(ii)
hereof.

                  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 Right
Certificate to or on the Company shall be sufficiently given or made if sent by

holders of Right Certificates in order to cure any ambiguity, to correct or
supplement any provision contained herein which may be defective or inconsistent
with any other provisions herein, or to make any other provisions with respect
to the Rights which the Company may deem necessary or desirable, any such

the Rights Agent; provided, however, that, from and after such time as any

plan of the Company or any Subsidiary of the Company, or any entity holding
Common Shares for or pursuant to the terms of any such plan) and (b) 10%.

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

                         ANADARKO PETROLEUM CORPORATION

                         (Pursuant to Section 151 of the
                        Delaware General Corporation Law)

                             ----------------------

                  Anadarko Petroleum Corporation, a corporation organized and
existing under the General Corporation Law of the State of Delaware (hereinafter
called the "Corporation"), hereby certifies that the following resolution was
adopted by the Board of Directors of the Corporation as required by Section 151
of the General Corporation Law at a meeting duly called and held on October 29,
1998:

                  RESOLVED, that pursuant to the authority granted to and vested
in the Board of Directors of this Corporation (hereinafter called the "Board of
Directors" or the "Board") in accordance with the provisions of the Certificate
of Incorporation, the Board of Directors hereby creates a series of Preferred
Stock, par value $1.00 per share, of the Corporation (the "Preferred Stock"),
and hereby states the designation and number of shares, and fixes the relative
rights, preferences, and limitations thereof as follows:

                  Series C Junior Participating Preferred Stock:

                  Section 1. Designation and Amount. The shares of such series
shall be designated as "Series C Junior Participating Preferred Stock" (the
"Series C Preferred Stock") and the number of shares constituting the Series C
Preferred Stock shall be 200,000. Such number of shares may be increased or
decreased by resolution of the Board of Directors; provided, that no decrease
shall reduce the number of shares of Series C Preferred Stock to a number less
than the number of shares then outstanding plus the number of shares reserved
for issuance upon the ex-


                                      A-1
<PAGE>

ercise of outstanding options, rights or warrants or upon the conversion of any
outstanding securities issued by the Corporation convertible into Series C
Preferred Stock.

                  Section 2. Dividends and Distributions.

                  (A) Subject to the rights of the holders of any shares of any
         series of Preferred Stock (or any similar stock) ranking prior and
         superior to the Series C Preferred Stock with respect to dividends, the
         holders of shares of Series C Preferred Stock, in preference to the
         holders of Common Stock, par value $0.10 per share (the "Common
         Stock"), of the Corporation, and of any other junior 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 last day of September, December, March and June
         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 C Preferred Stock, in an amount per share (rounded to the
         nearest cent) equal to the greater of (a) $1 or (b) subject to the
         provision for adjustment hereinafter set forth, 1,000 times the
         aggregate per share amount of all cash dividends, and 1,000 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 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 C Preferred
         Stock. In the event the Corporation shall at any time declare or pay
         any dividend on the Common Stock payable in shares of Common Stock, or
         effect a subdivision or combination or consolidation of the outstanding
         shares of Common Stock (by reclassification or otherwise than by
         payment of a dividend in shares of Common Stock) into a greater or
         lesser number of shares of Common Stock, then in each such case the
         amount to which holders of shares of Series C Preferred Stock were
         entitled immediately prior to such event under clause (b) of the
         preceding sentence shall be adjusted by multiplying such amount 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 C Preferred Stock as provided in paragraph (A) of this
         Section 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 per share on the Series C 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 C Preferred Stock from the Quarterly
         Dividend Payment Date next preceding the 

                                      A-2
<PAGE>

         date of issue of such shares, 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 C 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 C Preferred Stock in an amount less than
         the total amount of such dividends at the time accrued and payable on
         such 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 C
         Preferred Stock entitled to receive payment of a dividend or
         distribution declared thereon, which record date shall be not more than
         60 days prior to the date fixed for the payment thereof.

                  Section 3. Voting Rights. The holders of shares of Series C
Preferred Stock shall have the following voting rights:

                  (A) Subject to the provision for adjustment hereinafter set
         forth, each share of Series C Preferred Stock shall entitle the holder
         thereof to 1,000 votes on all matters submitted to a vote of the
         stockholders of the Corporation. In the event the Corporation shall at
         any time declare or pay any dividend on the Common Stock payable in
         shares of Common Stock, or effect a subdivision or combination or
         consolidation of the outstanding shares of Common Stock (by
         reclassification or otherwise than by payment of a dividend in shares
         of Common Stock) into a greater or lesser number of shares of Common
         Stock, then in each such case the number of votes per share to which
         holders of shares of Series C Preferred Stock were entitled immediately
         prior to such event shall be adjusted by multiplying such 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) Except as otherwise provided herein, in any other
         Certificate of Designations creating a series of Preferred Stock or any
         similar stock, or by law, the holders of shares of Series C Preferred
         Stock and the holders of shares of Common Stock and any other capital
         stock of the Corporation having general voting rights shall vote
         together as one class on all matters submitted to a vote of
         stockholders of the Corporation.

                  (C) Except as set forth herein, or as otherwise provided by
         law, holders of Series C Preferred Stock shall have no special voting
         rights and their consent shall not be required (except to the extent
         they are entitled to vote with holders of Common Stock as set forth
         herein) for taking any corporate action.

                  Section 4. Certain Restrictions.

                  (A) Whenever quarterly dividends or other dividends or
         distributions payable on the Series C 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 C Preferred Stock outstanding shall have been paid in full, the
         Corporation shall not:

                           (i) declare or pay dividends, or make any other
                  distributions, on any shares of stock ranking junior (either
                  as to dividends or upon liquidation, dissolution or winding
                  up) to the Series C Preferred Stock;

                           (ii) declare or pay dividends, 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 C Preferred Stock, except
                  dividends paid ratably on the Series C 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 junior (either as to
                  dividends or upon liquidation, dissolution or winding up) to
                  the Series C Preferred Stock, provided that the Corporation
                  may at any time redeem, purchase or otherwise acquire shares
                  of any such junior stock in exchange for shares of any stock
                  of the Corporation ranking junior (either as to dividends or
                  upon dissolution, liquidation or winding up) to the Series C
                  Preferred Stock; or

                           (iv) redeem or purchase or otherwise acquire for
                  consideration any shares of Series C Preferred Stock, or any
                  shares of stock ranking on a parity with the Series C
                  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.

                  Section 5. Reacquired Shares. Any shares of Series C 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 part of a new series
of Preferred Stock subject to the conditions and restrictions on issuance set
forth herein, in 

                                      A-4
<PAGE>

the Certificate of Incorporation, or in any other Certificate of Designations
creating a series of Preferred Stock or any similar stock or as otherwise
required by law.

                  Section 6. Liquidation, Dissolution or Winding Up. Upon any
liquidation, dissolution or winding up of the Corporation, no distribution shall
be made (1) to the holders of shares of stock ranking junior (either as to
dividends or upon liquidation, dissolution or winding up) to the Series C
Preferred Stock unless, prior thereto, the holders of shares of Series C
Preferred Stock shall have received $1,000 per share, plus an amount equal to
accrued and unpaid dividends and distributions thereon, whether or not declared,
to the date of such payment, provided that the holders of shares of Series C
Preferred Stock shall be entitled to receive an aggregate amount per share,
subject to the provision for adjustment hereinafter set forth, equal to 1,000
times the aggregate amount to be distributed per share to holders of shares of
Common Stock, or (2) to the holders of shares of stock ranking on a parity
(either as to dividends or upon liquidation, dissolution or winding up) with the
Series C Preferred Stock, except distributions made ratably on the Series C
Preferred Stock and all such parity stock in proportion to the total amounts to
which the holders of all such shares are entitled upon such liquidation,
dissolution or winding up. In the event the Corporation shall at any time
declare or pay any dividend on the Common Stock payable in shares of Common
Stock, or effect a subdivision or combination or consolidation of the
outstanding shares of Common Stock (by reclassification or otherwise than by
payment of a dividend in shares of Common Stock) into a greater or lesser number
of shares of Common Stock, then in each such case the aggregate amount to which
holders of shares of Series C Preferred Stock were entitled immediately prior to
such event under the proviso in clause (1) of the preceding sentence shall be
adjusted by multiplying such amount 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.

                  Section 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 each share
of Series C Preferred Stock shall at the same time be similarly exchanged or
changed into an amount per share, subject to the provision for adjustment
hereinafter set forth, equal to 1,000 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.
In the event the Corporation shall at any time declare or pay any dividend on
the Common Stock payable in shares of Common Stock, or effect a subdivision or
combination or consolidation of the outstanding shares of Common Stock (by
reclassification or otherwise than by payment of a dividend in shares of Common
Stock) into a greater or lesser number of shares of Common Stock, then in each
such case the amount set forth in the preceding sentence with respect to the
exchange or change of shares of Series C Preferred Stock shall be adjusted by
multiplying such amount 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.

                  Section 8. Redemption. (A) The Corporation shall have the
option to redeem in whole, but not in part, the Series C Preferred Stock at any
time at a redemption price equal to, subject to the provisions for adjustment
hereinafter set forth, 1,000 times the "current per share market price" 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. In the event
the Corporation shall at any time after November 10, 1998, (i) declare any
dividend on Common Stock payable in shares of Common Stock, (ii) subdivide the
outstanding Common Stock or (ii) combine the outstanding Common Stock into a
smaller number of shares, then in each such case the amount to which holders of
shares of Series C Preferred Stock were otherwise entitled immediately prior to
such event under the preceding sentence shall be adjusted by multiplying such
amount 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. 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 10
consecutive Trading Days (as such term is hereinafter defined) immediately prior
to such date. The closing price for each day shall be the last sale 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 consolidated transaction reporting system with respect
to securities listed or admitted to trading 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 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 Quotation System ("NASDAQ") or
such other system then in use or, if on any such date the Common Stock is not
quoted by any such organization, 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 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 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) Notice of any such redemption shall be given by mailing to
the holders of the Series C Preferred Stock a notice of such redemption, first
class postage prepaid, not later than the thirtieth 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. Any notice which 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
C Preferred Stock shall not affect the validity of the proceedings for the
redemption of such Series C Preferred Stock.

                                      A-6
<PAGE>

                  (C) If any such notice of redemption shall have been duly
given or if the Corporation shall have given to the bank or trust company
hereinafter referred to irrevocable written authorization promptly to give or
complete such notice, and if on or before the redemption date specified therein
the funds necessary for such redemption shall have been deposited by the
Corporation with the bank or trust company designated in such notice, doing
business in the United States of America and having a capital, surplus and
undivided profits aggregating at least $50,000,000 according to its last
published statement of condition, in trust for the benefit of the holders of
Series C Preferred Stock called for redemption, then, notwithstanding that any
certificate for such shares so called for redemption shall not have been
surrendered for cancellation, from and after the time of such deposit all such
shares called for redemption shall no longer be deemed outstanding and all
rights with respect to such shares shall no longer be deemed outstanding and all
rights with respect to such shares shall forthwith cease and terminate, except
the rights of the holders thereof to receive from such bank or trust company at
any time after the time of such deposit the funds so deposited, without
interest. Any interest accrued on such funds shall be paid to the Corporation
from time to time. Any funds so deposited and unclaimed at the end of six years
from such redemption date shall be repaid to the Corporation, after which the
holders of shares of Series C Preferred Stock called for redemption shall look
only to the Corporation for payment thereof.

                  Section 9. Rank. The Series C Preferred Stock shall rank, with
respect to the payment of dividends and the distribution of assets, junior to
all series of any other class of the Corporation's Preferred Stock.

                  Section 10. Amendment. The Certificate of Incorporation 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 C Preferred Stock
so as to affect them adversely without the affirmative vote of the holders of at
least two-thirds of the outstanding shares of Series C Preferred Stock, voting
together as a single class.

                          SUMMARY OF RIGHTS TO PURCHASE
                                PREFERRED SHARES


Introduction
- ------------
                  On October 29, 1998, the Board of Directors of Anadarko
Petroleum Corporation (the "Company") declared a dividend of one preferred share
purchase right (a "Right") for each outstanding share of common stock, par value
$0.10 per share, of the Company (the "Common Shares"). The dividend is payable
on November 10, 1998 (the "Record Date") to the stockholders of record on that
date. The description and terms of the Rights are set forth in an Agreement (the
"Agreement") between the Company and The Chase Manhattan Bank, as Rights Agent 
(the "Rights Agent").

Purchase Price
- --------------
                  Each Right entitles the registered holder to purchase from the
Company one one-thousandth of a share of Series C Junior Participating Preferred
Stock of the Company, par value $1.00 per share (the "Preferred Shares"), at a
price of $175 per one one-thousandth of a Preferred Share (the "Purchase
Price"), subject to adjustment.

Flip-In
- -------
                  In the event that any person or group of affiliated or
associated persons acquires beneficial ownership of 15% or more of the
outstanding Common Shares (an "Acquiring Person"), each holder of a Right, other
than Rights beneficially owned by the Acquiring Person (which will thereafter be
void), will thereafter have the right to receive upon exercise that number of
Common Shares having a market value of two times the exercise price of the
Right.

Flip-Over
- ---------
                  If the Company is acquired in a merger or other business
combination transaction or 50% or more of its consolidated assets or earning
power are sold after a person or group has become an Acquiring Person, each
holder of a Right (other than Rights beneficially owned by Acquiring Person,
which will be void) will thereafter have the right to receive that number of
shares of common stock of the acquiring company which at the time of such
transaction will have a market value of two times the exercise price of the
Right.

Distribution Date
- -----------------
                  The distribution date is the earlier of

                  (i) 10 days following a public announcement that a person or
group of affiliated or associated persons have acquired beneficial ownership of
15% or more of the outstanding Common Shares; or

                  (ii) 10 business days (or such later date as may be determined
by action of the Board of Directors of the Company prior to such time as any
person or group of affiliated persons becomes an Acquiring Person) following the
commencement of, or announcement of an intention to make, a tender offer or
exchange offer the consummation of which would result in the beneficial
ownership by a person or group of 15% or more of the outstanding Common Shares.

Transfer and Detachment
- -----------------------
                  Until the Distribution Date, the Rights will be evidenced,
with respect to any of the Common Share certificates outstanding as of the
Record Date, by such Common Share certificate with a copy of this Summary of
Rights attached thereto. Until the Distribution Date (or earlier redemption or
expiration of the Rights), the Rights will be transferred with and only with the
Common Shares, and transfer of those certificates will also constitute transfer
of these Rights.

                  As soon as practicable following the Distribution Date,
separate certificates evidencing the Rights ("Right Certificates") will be
mailed to holders of record of the Common Shares as of the close of business on
the Distribution Date and such separate Right Certificates alone will thereafter
evidence the Rights.

Exercisability
- --------------
                  The Rights are not exercisable until the Distribution Date.
The Rights will expire on November 10, 2008 (the "Final Expiration Date"),
unless the Final Expiration Date is extended or unless the Rights are earlier
redeemed or exchanged by the Company, in each case, as described below.

Adjustments
- -----------
                  The Purchase Price payable, and the number of Preferred Shares
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
stock dividends, stock splits, reclassifications, or certain distributions with
respect to the Preferred Shares. The number of outstanding Rights and the number
of one one-thousandths of a Preferred Share issuable upon exercise of each Right
are also subject to adjustment if, prior to the Distribution Date, there is a
stock split of the Common Shares or a stock dividend on the Common Shares
payable in Common Shares or subdivisions, consolidations or combinations of the
Common Shares. With certain exceptions, no adjustment in the Purchase Price will
be required until cumulative adjustments require an adjustment of at least 1% in
such Purchase Price. No fractional Preferred Shares will be issued (other than
fractions which 

                                      C-2
<PAGE>

are integral multiples of one one-thousandth of a Preferred Share, which may, at
the election of the Company, be evidenced by depositary receipts) and, in lieu
thereof, an adjustment in cash will be made based on the market price of the
Preferred Shares on the last trading day prior to the date of exercise.

Preferred Shares
- ----------------
                  Each Preferred Share will be entitled to a minimum
preferential quarterly dividend payment of $1 per share but will be entitled to
an aggregate dividend of 1,000 times the dividend declared per Common Share. In
the event of liquidation, the holders of the Preferred Shares will be entitled
to a minimum preferential liquidation payment of $1,000 per share but will be
entitled to an aggregate payment of 1,000 times the payment made per Common
Share. Each Preferred Share will have 1,000 votes, voting together with the
Common Shares. Finally, in the event of any merger, consolidation or other
transaction in which Common Shares are exchanged, each Preferred Share will be
entitled to receive 1,000 times the amount received per Common Share.
These rights are protected by customary antidilution provisions.

                  The value of the one one-thousandth interest in a Preferred
Share purchasable upon exercise of each Right should, because of the nature of
the Preferred Shares' dividend, liquidation and voting rights, approximate the
value of one Common Share.

Exchange
- --------
                  At any time after any person or group becomes an Acquiring
Person, and prior to the acquisition by such person or group of 50% or more of
the outstanding Common Shares, the Board of Directors of the Company may
exchange the Rights (other than Rights owned by the Acquiring Person, which will
have become void), in whole or in part, at an exchange ratio of one Common
Share, or one one-thousandth of a Preferred Share (subject to adjustment).

Redemption
- ----------
                  At any time prior to any person or group becoming an Acquiring
Person, the Board of Directors of the Company may redeem the Rights in whole,
but not in part, at a price of $.01 per Right (the "Redemption Price"). The
redemption of the Rights may be made effective at such time on such basis with
such conditions as the Board of Directors in its sole discretion may establish.
Immediately upon any redemption of the Rights, the right to exercise the Rights
will terminate and the only right of the holders of Rights will be to receive
the Redemption Price.

Amendments
- ----------
                  The terms of the Rights may be amended by the Board of
Directors of the Company without the consent of the holders of the Rights,
including an amendment to lower certain thresholds described above to not less
than the greater of (i) the sum of .001% and the largest percentage of the
outstanding Common Shares then known to the Company to be beneficially owned by
any person or group of affiliated or associated persons and (ii) 10%, except
that from and after such time as any person or group of affiliated or associated
persons becomes an Ac-

                                      C-3
<PAGE>

quiring Person no such amendment may adversely affect the interests of the
holders of the Rights.

Rights and Holders
- ------------------
                  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.

Exchange Commission as an Exhibit to a Registration Statement on Form 8-A dated
