Item 5.  Other Events.

         On January 8, 1996, the Board of Directors of Helmerich & Payne, Inc.,
(the "Company") approved the extension of the benefits afforded by the
Company's existing rights plan by adopting a new stockholder rights plan.  The
new plan, like the existing plan, is intended to promote continuity and
stability, deter coercive or partial offers which will not provide fair value
to all stockholders and enhance the Board's ability to represent all
stockholders and thereby maximize stockholder values.

         Pursuant to the new Rights Agreement between the Company and Liberty
Bank and Trust Company of Oklahoma City, N.A., as Rights Agent (the "1996
Rights Agreement"), one Right will be issued for each outstanding share of
common stock, par value $.10 per share (the "Common Stock"), of the Company on
the expiration of the existing rights (the close of business on January 8,
1996).  Each of the new Rights will entitle the registered holder to purchase
from the Company one one-thousandth of a share of Series A Junior Participating
Preferred Stock, without par value, at a price of $90 per one one-thousandth of
a share.  The Rights, however, will not become exercisable unless and until,
among other things, any person acquires 15% or more of the outstanding Common
Stock.  The new Rights are redeemable under certain circumstances at $.01 per
Right and will expire, unless earlier redeemed, on January 31,  2006.

         The description and terms of the new Rights are set forth in the 1996
Rights Agreement, a copy of which is filed herewith and is incorporated herein
by reference.

the right to purchase one share of Common Stock, upon the terms and subject to
the conditions set forth in the 1986 Agreement (the "1986 Rights");

                 WHEREAS, on December 5, 1990, the Board of Directors, in
accordance with Section 26 of the 1986 Agreement, determined it desirable and
in the best interests of the Company and its stockholders for the Company to

                 Section 1.  Certain 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 shares of Common Stock then outstanding,
but shall not include (i) the Company, any Subsidiary of the Company, any
employee benefit plan of the Company or of any Subsidiary of the Company, or
any Person or entity organized, appointed or established by the Company for or
pursuant to the terms of any such plan, (ii) any such Person who becomes an
Acquiring Person solely as a result of a reduction in the number of shares of
Common Stock outstanding due to the repurchase of shares of Common Stock by the
Company, unless and until such Person shall purchase or otherwise become the
Beneficial Owner of additional shares of Common Stock constituting 1% or more
of the then outstanding shares of Common Stock other than pursuant to a tender
or exchange offer for all outstanding shares of Common Stock as set forth in
Section 11(a)(ii) hereof or (iii) any such Person who has reported or is
required to report such ownership (but less than 25%) on Schedule 13G under the
Exchange Act (as such term is hereinafter defined) (or any comparable or
successor





                                       2

report) or on Schedule 13D under the Exchange Act (or any comparable or
successor report) which Schedule 13D does not state any intention to or reserve
the right to control or influence the management or policies of the Company or
engage in any of the actions specified in Item 4 of such Schedule (other than
the disposition of the Common Stock) and, within 10 Business Days (as such term
is hereinafter defined) of being requested by the Company to advise it
regarding the same, certifies to the Company that such Person acquired shares
of Common Stock in excess of 14.9% inadvertently or without knowledge of the
terms of the Rights and who, together with all Affiliates and Associates,
thereafter does not acquire additional shares of Common Stock while the
Beneficial Owner of 15% or more of the shares of Common Stock then outstanding;
provided, however, that if the Person requested to so certify fails to do so
within 10 Business Days, then such Person shall become an Acquiring Person
immediately after such 10 Business Day period.

                          (b)  "Affiliate" and "Associate" shall have the
respective meanings ascribed to such terms in Rule 12b-2 of the General Rules
and Regulations under the Securities Exchange Act of 1934, as amended and in
effect on the date of this Agreement (the "Exchange Act").

                          (c)  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, directly or indirectly, has the
         right to acquire (whether such right is exercisable immediately or
         only after the passage of time) pursuant to any agreement, arrangement
         or understanding (whether or not in writing) or upon the exercise of
         conversion rights, exchange rights, rights, warrants or options, or
         otherwise; provided, however, that a Person shall not be deemed the
         "Beneficial Owner" of, or to "beneficially own," (A) securities
         tendered pursuant to a tender or exchange offer made by such Person or
         any of such Person's Affiliates or Associates until such tendered
         securities are accepted for purchase or ex-change, or (B) securities
         issuable upon exercise of Rights at any time prior to the occur-

         rence of a Triggering Event, or (C) securities issuable upon exercise
         of Rights from and after the occurrence of a Triggering Event which
         Rights were acquired by such Person or any of such Person's Affiliates
         or Associates prior to the Distribution Date or pursuant to Section
         3(a) or Section 22 hereof (the "Original Rights") or pursuant to

Business Day after the Stock Acquisition Date occurs before the Record Date,

                                       6

and Regulations under the Exchange Act, if upon consummation thereof, such
Person would be the Beneficial Owner of 15% or more of the shares of Common
Stock then outstanding (the earlier of (i) and (ii) being herein referred to as
the "Distribution Date"), (x) the Rights will be evidenced (subject to the
provisions of paragraph (b) of this Section 3) by the certificates for the
Common Stock registered in the names of the holders of the Common Stock (which
certificates for Common Stock shall be deemed also to be certificates for
Rights) and not by separate certificates, and (y) the Rights will be
transferable only in connection with the transfer of the underlying shares of
Common Stock (including a transfer to the Company).  As soon as practicable
after the Distribution Date, the Rights Agent will send by first-class,
insured, postage prepaid mail, to each record holder of the Common Stock as of
the close of business on the Distribution Date, at the address of such holder
shown on the records of the Company, one or more right certificates, in
substantially the form of Exhibit B hereto (the "Rights Certificates"),
evidencing one Right for each share of Common Stock so held, subject to
adjustment as provided herein.  In the event that an adjustment in the number
of Rights per share of Common Stock has been made pursuant to Section 11(p)
hereof, at the time of distribution of the Right Certificates, the Company
shall make the necessary and appropriate rounding adjustments (in accordance
with Section 14(a) hereof) so that Rights Certificates representing only whole
numbers of Rights are distributed and cash is paid in lieu of any fractional
Rights.  As of and after the Distribution Date, the Rights will be evidenced
solely by such Rights Certificates.

                          (b)  The Company will make available a copy of a
Summary of Rights, in substantially the form attached hereto as Exhibit C (the
"Summary of Rights") to any holder of Rights who may so request from time to
time.  With respect to certificates for the Common Stock outstanding as of the
Record Date, until the Distribution Date, the Rights will be evidenced by such
certificates for the Common Stock and the registered holders of the Common
Stock shall also be the registered holders of the associated Rights.  Until the
earlier of the Distribution Date or the Expiration Date (as hereafter defined),
the transfer of any certificates representing shares of Common Stock in respect
of which Rights have been issued





                                       7
<PAGE>   11
shall also constitute the transfer of the Rights associated with such shares of
Common Stock.

                          (c)  Rights shall be issued in respect of all shares
of Common Stock which are issued (whether originally issued or from the
Company's treasury) after the Record Date but prior to the earlier of the
Distribution Date or the Expiration Date.  Certificates representing such
shares of Common Stock shall also be deemed to be certificates for Rights, and
shall bear the following legend (or the legend required under the 1986
Agreement):

                 This certificate also evidences and entitles the holder hereof
         to certain Rights as set forth in the Rights Agreement between
         Helmerich & Payne, Inc. (the "Company") and the Rights Agent
         thereunder dated as of January 8, 1996 (the "Rights Agreement"), the
         terms of which are hereby incorporated herein by reference and a copy
         of which is on file at the principal offices of the Company.  Under
         certain circumstances, as set forth in the Rights Agreement, such
         Rights will be evidenced by separate certificates and will no longer
         be evidenced by this certificate.  The Company will mail to the holder
         of this certificate a copy of the Rights Agreement, as in effect on
         the date of mailing, without charge promptly after receipt of a
         written request therefor.  Under certain circumstances set forth in
         the Rights Agreement, Rights issued to, or held by, any Person who is,
         was or becomes an Acquiring Person or any Affiliate or Associate
         thereof (as such terms are defined in the Rights Agreement), whether
         currently held by or on behalf of such Person or by any subsequent
         holder, may become null and void.

With respect to such certificates containing the foregoing legend (or the
legend required under the 1986 Agreement), until the earlier of (i) the
Distribution Date or (ii) the Expiration Date, the Rights associated with the
Common Stock represented by such certificates shall be evidenced by such
certificates alone and registered holders of Common Stock shall also be the
registered holders of the associated Rights, and the transfer





                                       8
<PAGE>   12
of any of such certificates shall also constitute the transfer of the Rights
associated with the Common Stock represented by such certificates.

                 Section 4.  Form of Rights Certificates.

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

                          (b)  Any Rights Certificate issued pursuant to
Section 3(a) or Section 22 hereof that represents Rights beneficially owned by:
(i) an Acquiring Person or any Associate or Affiliate of an Acquiring Person,
(ii) a transferee of an Acquiring Person (or of any such Associate or
Affiliate) who becomes a transferee after the Acquiring Person becomes such, or
(iii) a transferee of an Acquiring Person (or of any such Associate or
Affiliate) who becomes a transferee prior to or concurrently with the Acquiring
Person becoming such and receives such Rights pursuant to either (A) a transfer
(whether or not for consideration) from the Acquiring Person to holders of
equity interests in such Acquiring Person or to any Person with whom such
Acquiring Person has any continuing agreement, arrangement or understanding
regarding the transferred Rights or (B) a transfer which the Board of Directors
of the Company has deter





                                       9
<PAGE>   13
mined is part of a plan, arrangement or understanding which has as a primary
purpose or effect avoidance of Section 7(e) hereof, and any Rights Certificate
issued pursuant to Section 6 or Section 11 hereof upon transfer, exchange,
replacement or adjustment of any other Rights Certificate referred to in this
sentence, shall contain (to the extent feasible) the following legend:

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

                 Section 5.  Countersignature and Registration.

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

<PAGE>   14
                          (b)  Following the Distribution Date, the Rights 
Agent will keep or cause to be kept, at its principal office or offices
designated as the appropriate place for surrender of Rights Certificates upon
exercise or transfer, books for registration and transfer of the Rights
Certificates issued hereunder.  Such books shall show the names and addresses
of the respective holders of the Rights Certificates, the number of Rights
evidenced on its face by each of the Rights Certificates and the date of each
of the Rights Certificates.

                 Section 6.  Transfer, Split Up, Combination and Exchange of
Rights Certificates; Mutilated, Destroyed, Lost or Stolen Rights Certificates.
(a)  Subject to the provisions of Section 4(b), Section 7(e) and 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 Expiration Date, any Rights
Certificate or Certificates (other than Rights Certificates representing Rights
that have been exchanged pursuant to Section 24 hereof) may be transferred,
split up, combined or exchanged for another Rights Certificate or Certificates,
entitling the registered holder to purchase a like number of one one-thousandth
of a share of Preferred Stock (or, following a Triggering Event, Common Stock,
other securities, cash or other assets, as the case may be) as the Rights
Certificate or Certificates surrendered then entitled such holder (or former
holder in the case of a transfer) to purchase.  Any registered holder desiring
to transfer, split up, combine or exchange any Rights Certificate or
Certificates shall make such request in writing delivered to the Rights Agent,
and shall surrender the Rights Certificate or Certificates to be transferred,
split up, combined or exchanged at the principal office or offices of the
Rights Agent designated for such purpose.  Neither the Rights Agent nor the
Company shall be obligated to take any action whatsoever with respect to the
transfer of any such surrendered Rights Certificate until the registered holder
shall have completed and signed the certificate contained in the form of
assignment on the reverse side of such Rights Certificate and shall have
provided such additional evidence of the identity of the Beneficial Owner (or
former Beneficial Owner) or Affiliates or Associates thereof as the Company
shall reasonably request.  Thereupon the Rights Agent shall, subject to Section
4(b), Section 7(e), Section 14 and Section 24 hereof,





                                       11
<PAGE>   15
countersign and deliver to the Person entitled thereto a Rights Certificate or
Rights Certificates, as the case may be, as so requested.  The Company may
require payment of a sum sufficient to cover any tax or governmental charge
that may be imposed in connection with any transfer, split up, combination or
exchange of Rights Certificates.

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

                 Section 7.  Exercise of Rights; Purchase Price; Expiration
Date of Rights.  (a)  Subject to Section 7(e) hereof, the registered holder of
any Rights Certificate may exercise the Rights evidenced thereby (except as
otherwise provided herein including, without limitation, the restrictions on
exercisability set forth in Section 9(c), Section 11(a)(iii) and Section 23(a)
hereof) in whole or in part at any time after the Distribution Date upon
surrender of the Rights Certificate, with the form of election to purchase and
the certificate on the reverse side thereof duly executed, to the Rights Agent
at the principal office or offices of the Rights Agent designated for such
purpose, together with payment of the aggregate Purchase Price with respect to
the total number of one one-thousandth of a share (or other securities, cash or
other assets, as the case may be) as to which such surrendered Rights are then
exercisable, at or prior to the earliest of (i) the close of business on
January 31, 2006, (the "Final Expiration Date"), (ii) the time at which the
Rights are redeemed as provided in Section 23 hereof or (iii) the time at which
such Rights are exchanged pursuant to Section 24 hereof (the earliest of (i),
(ii) and (iii) being herein referred to as the "Expiration Date").





                                       12
<PAGE>   16
                          (b)  The Purchase Price for each one one-thousandth
of a share of Preferred Stock pursuant to the exercise of a Right shall
initially be $90, and shall be subject to adjustment from time to time as
provided in Sections 11 and 13(a) hereof and shall be payable in accordance
with paragraph (c) below.

                          (c)  Upon receipt of a Rights Certificate
representing exercisable Rights, with the form of election to purchase and the
certificate duly executed, accompanied by payment, with respect to each Right
so exercised, of the Purchase Price per one one-thousandth of a share of
Preferred Stock (or other shares, securities, cash or other assets, as the case
may be) to be purchased as set forth below and an amount equal to any
applicable transfer tax, the Rights Agent shall, subject to Section 20(k)
hereof, thereupon promptly (i) (A) requisition from any transfer agent of the
shares of Preferred Stock (or make available, if the Rights Agent is the
transfer agent for such shares) certificates for the total number of one
one-thousandth of a share of Preferred Stock to be purchased and the Company
hereby irrevocably authorizes its transfer agent to comply with all such
requests, or (B) if the Company shall have elected to deposit the total number
of shares of Preferred Stock issuable upon exercise of the Rights hereunder
with a depositary agent, requisition from the depositary agent depositary
receipts representing such number of one one-thousandth of a share of Preferred
Stock as are to be purchased (in which case certificates for the shares of
Preferred Stock represented by such receipts shall be deposited by the transfer
agent with the depositary agent) and the Company will direct the depositary
agent to comply with such request, (ii) requisition from the Company the amount
of cash, if any, to be paid in lieu of fractional shares in accordance with
Section 14 hereof, (iii) after receipt of such certificates or depositary
receipts, cause the same to be delivered to or upon the order of the registered
holder of such Rights Certificate, registered in such name or names as may be
designated by such holder, and (iv) after receipt thereof, deliver such cash,
if any, to or upon the order of the registered holder of such Rights
Certificate.  The payment of the Purchase Price (as such amount may be reduced
pursuant to Section 11(a)(iii) hereof) shall be made in cash or by certified
bank check or bank draft payable to the order of the Company.  In the event
that





                                       13
<PAGE>   17
the Company is obligated to issue other securities (including Common Stock) of
the Company, pay cash and/or distribute other property pursuant to Section
11(a) hereof, the Company will make all arrangements necessary so that such
other securities, cash and/or other property are available for distribution by
the Rights Agent, if and when appropriate.  The Company reserves the right to
require prior to the occurrence of a Triggering Event that, upon any exercise
of Rights, a number of Rights be exercised so that only whole shares of
Preferred Stock would be issued.

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

                          (e)  Notwithstanding anything in this Agreement to
the contrary, from and after the first occurrence of a Section 11(a)(ii) Event,
any Rights beneficially owned by (i) an Acquiring Person or an Associate or
Affiliate of an Acquiring Person, (ii) a transferee of an Acquiring Person (or
of any such Associate or Affiliate) who becomes a transferee after the
Acquiring Person becomes such, or (iii) a transferee of an Acquiring Person (or
of any such Associate or Affiliate) who becomes a transferee prior to or
concurrently with the Acquiring Person becoming such and receives such Rights
pursuant to either (A) a transfer (whether or not for consideration) from the
Acquiring Person to holders of equity interests in such Acquiring Person or to
any Person with whom the Acquiring Person has any continuing agreement,
arrangement or understanding regarding the transferred Rights or (B) a transfer
which the Board of Directors of the Company has determined is part of a plan,
arrangement or understanding which has as a primary purpose or effect the
avoidance of this Section 7(e), shall become null and void without any further
action and no holder of such Rights shall have any rights whatsoever with
respect to such Rights, whether under any provision of this Agreement or
otherwise.  The Company shall use all reasonable efforts to insure that the
provisions of





                                       14
<PAGE>   18
this Section 7(e) and Section 4(b) hereof are complied with, but shall have no
liability to any holder of Rights Certificates or other Person as a result of
its failure to make any determinations with respect to an Acquiring Person or
its Affiliates, Associates or transferees hereunder.

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

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

                 Section 9.  Reservation and Availability of Capital Stock.
(a)  The Company covenants and agrees that it will cause to be reserved and
kept available out of its authorized and unissued shares of Preferred Stock
(and, following the occurrence of a Triggering Event, out of its authorized and
unissued shares of Common Stock





                                       15
<PAGE>   19
and/or other securities or out of its authorized and issued shares held in its
treasury), the number of shares of Preferred Stock (and, following the
occurrence of a Triggering Event, Common Stock and/or other securities) that,
as provided in this Agreement including Section 11(a)(iii) hereof, will be
sufficient to permit the exercise in full of all outstanding Rights.

                          (b)  So long as the shares of Preferred Stock (and,
following the occurrence of a Triggering Event, Common Stock and/or other
securities) issuable and deliverable upon the exercise of the Rights may be
listed on any national securities exchange, the Company shall use its best
efforts to cause, from and after such time as the Rights become exercisable,
all shares reserved for such issuance to be listed on such exchange upon
official notice of issuance upon such exercise.

                          (c)  The Company shall use its best efforts to (i)
file, as soon as practicable following the earliest date after the first
occurrence of a Section 11(a)(ii) Event on which the consideration to be
delivered by the Company upon exercise of the Rights has been determined in
accordance with Section 11(a)(iii) hereof, a registration statement under the
Securities Act of 1933 (the "Act"), with respect to the securities purchasable
upon exercise of the Rights on an appropriate form, (ii) cause such
registration statement to become effective as soon as practicable after such
filing, and (iii) cause such registration statement to remain effective (with a
prospectus at all times meeting the requirements of the Act) until the earlier
of (A) the date as of which the Rights are no longer exercisable for such
securities, and (B) the date of the expiration of the Rights.  The Company will
also take such action as may be appropriate under, or to ensure compliance
with, the securities or "blue sky" laws of the various states in connection
with the exercisability of the Rights.  The Company may temporarily suspend,
for a period of time not to exceed ninety (90) days after the date set forth in
clause (i) of the first sentence of this Section 9(c), the exercisability of
the Rights in order to prepare and file such registration statement and permit
it to become effective.  Upon any such suspension, the Company shall issue a
public announcement stating that the exercisability of the Rights has been
temporarily suspended, as well as a public announcement at such time as the
suspension





                                       16
<PAGE>   20
is no longer in effect.  In addition, if the Company shall determine that a
registration statement is required following the Distribution Date, the Company
may temporarily suspend the exercisability of the Rights until such time as a
registration statement has been declared effective.  Notwithstanding any
provision of this Agreement to the contrary, the Rights shall not be
exercisable in any jurisdiction if the requisite qualification in such
jurisdiction has not been obtained, the exercise thereof is not permitted under
applicable law or a registration statement has not have been declared
effective.

                          (d)  The Company covenants and agrees that it will
take all such action as may be necessary to ensure that all one one-thousandth
of a share of Preferred Stock (and, following the occurrence of a Triggering
Event, Common Stock and/or other securities) delivered upon exercise of Rights
shall, at the time of delivery of the certificates for such shares (subject to
payment of the Purchase Price), be duly and validly authorized and issued and
fully paid and nonassessable.

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

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

                 Section 11.  Adjustment of Purchase Price, Number and Kind of
Shares or Number of Rights.  The Purchase Price, the number and kind of shares
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 Stock payable in shares of Preferred Stock, (B) subdivide
         the outstanding Preferred Stock, (C) combine the outstanding Preferred
         Stock into a smaller number of shares, or (D) issue any shares of its
         capital stock in a reclassification of the Preferred Stock





                                       18
<PAGE>   22
         (including any such reclassification in connection with a
         consolidation or merger in which the Company is the continuing or
         surviving corporation), except as otherwise provided in this Section
         11(a) and Section 7(e) hereof, the Purchase Price in effect at the
         time of the record date for such dividend or of the effective date of
         such subdivision, combination or reclassification, and the number and
         kind of shares of Preferred Stock or capital stock, as the case may
         be, issuable on such date, shall be proportionately adjusted so that
         the holder of any Right exercised after such time shall be entitled to
         receive, upon payment of the Purchase Price then in effect, the
         aggregate number and kind of shares of Preferred Stock or capital
         stock, as the case may be, which, if such Right had been exercised
         immediately prior to such date and at a time when the Preferred Stock
         transfer books of the Company were open, such holder would have owned
         upon such exercise and been entitled to receive by virtue of such
         dividend, subdivision, combination or reclassification.  If an event
         occurs which would require an adjustment under both this Section
         11(a)(i) and Section 11(a)(ii) hereof, the adjustment provided for in
         this Section 11(a)(i) shall be in addition to, and shall be made prior
         to, any adjustment required pursuant to Section 11(a)(ii) hereof.

                          (ii)    Subject to Section 24 of this Agreement, in
         the event that any Person, alone or together with its Affiliates and
         Associates, shall, at any time after the Rights Dividend Declaration
         Date, become an Acquiring Person, unless the event causing such Person
         to become an Acquiring Person is a transaction set forth in Section
         13(a) hereof, or is an acquisition of shares of Common Stock pursuant
         to a tender offer or an exchange offer for all outstanding shares of
         Common Stock at a price and on terms determined by at least a majority
         of the members of the Board of Directors who are not officers of the
         Company and who are not representatives, nominees, Affiliates or
         Associates of an Acquiring Person, after receiving advice





                                       19
<PAGE>   23
         from one or more investment banking firms, to be (a) at a price which
         is fair to stockholders (taking into account all factors which such
         members of the Board deem relevant including, without limitation,
         prices which could reasonably be achieved if the Company or its assets
         were sold on an orderly basis designed to realize maximum value) and
         (b) otherwise in the best interests of the Company and its
         stockholders (hereinafter, a "Qualifying Offer"), then, promptly
         following the occurrence of such event, proper provision shall be made
         so that each holder of a Right (except as provided below and in
         Section 7(e) hereof) shall thereafter have the right to receive, upon
         exercise thereof at the then current Purchase Price in accordance with
         the terms of this Agreement, in lieu of a number of one one-thousandth
         of a share of Preferred Stock, such number of shares of Common Stock
         of the Company as shall equal the result obtained by (x) multiplying
         the then current Purchase Price by the then number of one
         one-thousandth of a share of Preferred Stock for which a Right was
         exercisable immediately prior to the first occurrence of a Section
         11(a)(ii) Event, and (y) dividing that product (which, following such
         first occurrence, shall thereafter be referred to as the "Purchase
         Price" for each Right and for all purposes of this Agreement) by 50%
         of the Current Market Price (determined pursuant to Section 11(d)
         hereof) per share of Common Stock on the date of such first occurrence
         (such number of shares, the "Adjustment Shares").

                          (iii)  In the event that the number of shares of
         Common Stock which are authorized by the Company's certificate of
         incorporation but not outstanding or reserved for issuance for
         purposes other than upon exercise of the Rights are not sufficient to
         permit the exercise in full of the Rights in accordance with the
         foregoing subparagraph (ii) of this Section 11(a), the Company shall
         (A) determine the value of the Adjustment Shares issuable upon the
         exercise of a Right (the "Current Value"), and (B) with respect to
         each Right (subject to





                                       20
<PAGE>   24
         Section 7(e) hereof), make adequate provision to substitute for the
         Adjustment Shares, upon the exercise of a Right and payment of the
         applicable Purchase Price, (1) cash, (2) a reduction in the Purchase
         Price, (3) Common Stock or other equity securities of the Company
         (including, without limitation, shares, or units of shares, of
         preferred stock, such as the Preferred Stock, which the Board has
         deemed to have essentially the same value or economic rights as shares
         of Common Stock (such shares of preferred stock being referred to as
         "Common Stock Equivalents")), (4) debt securities of the Company, (5)
         other assets, or (6) any combination of the foregoing, having an
         aggregate value equal to the Current Value (less the amount of any
         reduction in the Purchase Price), where such aggregate value has been
         determined by the Board based upon the advice of a nationally
         recognized investment banking firm selected by the Board; provided,
         however, that if the Company shall not have made adequate provision to
         deliver value pursuant to clause (B) above within sixty (60) days
         following the later of (x) the first occurrence of a Section 11(a)(ii)
         Event and (y) the date on which the Company's right of redemption
         pursuant to Section 23(a) expires (the later of (x) and (y) being
         referred to herein as the "Section 11(a)(ii) Trigger Date"), then the
         Company shall be obligated to deliver, upon the surrender for exercise
         of a Right and without requiring payment of the Purchase Price, shares
         of Common Stock (to the extent available) and then, if necessary,
         cash, which shares and/or cash have an aggregate value equal to the
         Spread.  For purposes of the preceding sentence, the term "Spread"
         shall mean the excess of (i) the Current Value over (ii) the Purchase
         Price.  If the Board determines in good faith that it is likely that
         sufficient additional shares of Common Stock could be authorized for
         issuance upon exercise in full of the Rights, the sixty (60) day
         period set forth above may be extended to the extent necessary, but
         not more than ninety (90) days after the Section 11(a)(ii) Trigger
         Date, in order that the Company may





                                       21
<PAGE>   25
         seek stockholder approval for the authorization of such additional
         shares (such sixty (60) day period, as it may be extended, is herein
         called the "Substitution Period").  To the extent that action is to be
         taken pursuant to the first and/or third sentences of this Section
         11(a)(iii), the Company (1) shall provide, subject to Section 7(e)
         hereof, that such action shall apply uniformly to all outstanding
         Rights, and (2) may suspend the exercisability of the Rights until the
         expiration of the Substitution Period in order to seek such
         stockholder approval for such authorization of additional shares
         and/or to decide the appropriate form of distribution to be made
         pursuant to such first sentence and to determine the value thereof.
         In the event of any such suspension, the Company shall issue a public
         announcement stating that the exercisability of the Rights has been
         temporarily suspended, as well as a public announcement at such time
         as the suspension is no longer in effect.  For purposes of this
         Section 11(a)(iii), the value of each Adjustment Share shall be the
         Current Market Price per share of the Common Stock on the Section
         11(a)(ii) Trigger Date and the per share or per unit value of any
         Common Stock Equivalent shall be deemed to equal the Current Market
         Price per share of the Common Stock on such date.

                          (b)  In case the Company shall fix a record date for
the issuance of rights, options or warrants to all holders of Preferred Stock
entitling them to subscribe for or purchase (for a period expiring within
forty-five (45) calendar days after such record date) Preferred Stock (or
shares having the same rights, privileges and preferences as the shares of
Preferred Stock ("Equivalent Preferred Stock")) or securities convertible into
Preferred Stock or Equivalent Preferred Stock at a price per share of Preferred
Stock or per share of Equivalent Preferred Stock (or having a conversion price
per share, if a security convertible into Preferred Stock or Equivalent
Preferred Stock) less than the Current Market Price (as determined pursuant to
Section 11(d) hereof) per share of Preferred Stock on such record date, the
Purchase Price to be in effect after such record date shall be determined by
multiplying the





                                       22
<PAGE>   26
Purchase Price in effect immediately prior to such record date by a fraction,
the numerator of which shall be the number of shares of Preferred Stock
outstanding on such record date, plus the number of shares of Preferred Stock
which the aggregate offering price of the total number of shares of Preferred
Stock and/or Equivalent Preferred Stock so to be offered (and/or the aggregate
initial conversion price of the convertible securities so to be offered) would
purchase at such Current Market Price, and the denominator of which shall be
the number of shares of Preferred Stock outstanding on such record date, plus
the number of additional shares of Preferred Stock and/or Equivalent Preferred
Stock to be offered for subscription or purchase (or into which the convertible
securities so to be offered are initially convertible).  In case such
subscription price may be paid by delivery of consideration part or all of
which may be in a form other than cash, the value of such consideration shall
be as determined in good faith by the Board of Directors of the Company, whose
determination shall be described in a statement filed with the Rights Agent and
shall be binding on the Rights Agent and the holders of the Rights.  Shares of
Preferred Stock owned by or held for the account of the Company shall not be
deemed outstanding for the purpose of any such computation.  Such adjustment
shall be made successively whenever such a record date is fixed, and in the
event that such rights or warrants are not so issued, the Purchase Price shall
be adjusted to be the Purchase Price which would then be in effect if such
record date had not been fixed.

                          (c)  In case the Company shall fix a record date for
a distribution to all holders of Preferred Stock (including any such
distribution made in connection with a consolidation or merger in which the
Company is the continuing corporation) of evidences of indebtedness, cash
(other than a regular quarterly cash dividend out of the earnings or retained
earnings of the Company), assets (other than a dividend payable in Preferred
Stock, but including any dividend payable in stock other than Preferred Stock)
or subscription rights or warrants (excluding those referred to in Section
11(b) hereof), the Purchase Price to be in effect after such record date shall
be determined by multiplying the Purchase Price in effect immediately prior to
such record date by a fraction, the numerator of which shall be the Current
Market Price (as determined pursuant to Section





                                       23
<PAGE>   27
11(d) hereof) per share of Preferred Stock on such record date, less the fair
market value (as determined in good faith by the Board of Directors of the
Company, whose determination shall be described in a statement filed with the
Rights Agent) of the portion of the cash, assets or evidences of indebtedness
so to be distributed or of such subscription rights or warrants applicable to a
share of Preferred Stock and the denominator of which shall be such Current
Market Price (as determined pursuant to Section 11(d) hereof) per share of
Preferred Stock.  Such adjustments shall be made successively whenever such a
record date is fixed, and in the event that such distribution is not so made,
the Purchase Price shall be adjusted to be the Purchase Price which would have
been in effect if such record date had not been fixed.


                          (d)  (i)  For the purpose of any computation
hereunder, other than computations made pursuant to Section 11(a)(iii) hereof,
the Current Market Price per share of Common Stock on any date shall be deemed
to be the average of the daily closing prices per share of such Common Stock
for the thirty (30) consecutive Trading Days (as hereinafter defined)
immediately prior to such date, and for purposes of computations made pursuant
to Section 11(a)(iii) hereof, the Current Market Price per share of Common
Stock on any date shall be deemed to be the average of the daily closing prices
per share of such Common Stock for the ten (10) consecutive Trading Days
immediately following such date; provided, however, that in the event that the
Current Market Price per share of the Common Stock is deter- mined during a
period following the announcement by the issuer of such Common Stock of (A) a
dividend or distribution on such Common Stock payable in shares of such Common
Stock or securities convertible into shares of such Common Stock (other than
the Rights), or (B) any subdivision, combination or reclassification of such
Common Stock, and the ex-dividend date for such dividend or distribution, or
the record date for such subdivision, combination or reclassification shall not
have occurred prior to the commencement of the requisite thirty (30) Trading
Day or ten (10) Trading Day period, as set forth above, then, and in each such
case, the Current Market Price shall be properly adjusted to take into account
ex-dividend trading.  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





                                       24
<PAGE>   28
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 shares of Common Stock 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 shares of Common Stock are listed or admitted
to trading or, if the shares of Common Stock 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 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 shares of Common Stock 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 Common Stock
selected by the Board of Directors.  If on any such date no market maker is
making a market in the Common Stock, the fair value of such shares on such date
as determined in good faith by the Board of Directors shall be used.  The term
"Trading Day" shall mean a day on which the principal national securities
exchange on which the shares of Common Stock are listed or admitted to trading
is open for the transaction of business or, if the shares of Common Stock are
not listed or admitted to trading on any national securities exchange, a
Business Day.  If the Common Stock is not publicly held or not so listed or
traded, Current Market Price per share shall mean the fair value per share as
determined in good faith by the Board, whose determination shall be described
in a statement filed with the Rights Agent and shall be conclusive for all
purposes.

                          (ii)  For the purpose of any computation hereunder,
the Current Market Price per share of Preferred Stock shall be determined in
the same manner as set forth above for the Common Stock in clause (i) of this
Section 11(d) (other than the last sentence thereof).  If the Current Market
Price per share of Preferred Stock cannot be determined in the manner provided
above or if the Preferred Stock is not publicly held or listed or traded in a
manner described in clause (i) of





                                       25
<PAGE>   29
this Section 11(d), the Current Market Price per share of Preferred Stock shall
be conclusively deemed to be an amount equal to 1,000 (as such number may be
appropriately adjusted for such events as stock splits, stock dividends and
recapitalizations with respect to the Common Stock occurring after the date of
this Agreement) multiplied by the Current Market Price per share of the Common
Stock.  If neither the Common Stock nor the Preferred Stock is publicly held or
so listed or traded, Current Market Price per share of the Preferred Stock
shall mean the fair value per share as determined in good faith by the Board,
whose determination shall be described in a statement filed with the Rights
Agent and shall be conclusive for all purposes.  For all purposes of this
Agreement, the Current Market Price of a Unit shall be equal to the Current
Market Price of one share of Preferred Stock divided by 1,000.

                          (e)  Anything herein to the contrary notwithstanding,
no adjustment in the Purchase Price shall be required unless such adjustment
would require an increase or decrease of at least one percent (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 ten-thousandth of a
share of Common Stock or other share or one-ten millionth of a share of
Preferred Stock, as the case may be.  Notwithstanding the first sentence of
this Section 11(e), any adjustment required by this Section 11 shall be made no
later than the earlier of (i) three (3) years from the date of the transaction
which mandates such adjustment, or (ii) the Expiration Date.

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





                                       26
<PAGE>   30
sions of Sections 7, 9, 10, 13 and 14 hereof with respect to the Preferred
Stock shall apply on like terms to any such other shares.

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

                          (h)  Unless the Company shall have exercised its
election as provided in Section 11(i), upon each adjustment of the Purchase
Price as a result of the calculations made in Sections 11(b) and (c), 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-thousandth of a share of Preferred Stock (calculated to the
nearest one-ten millionth) obtained by (i) multiplying (x) the number of one
one-thousandth 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 (ii) dividing the product so obtained by
the Purchase Price in effect immediately after such adjustment of the Purchase
Price.

                          (i)  The Company may elect on or after the date of
any adjustment of the Purchase Price to adjust the number of Rights, in lieu of
any adjustment in the number of one one-thousandth of a share of Preferred
Stock purchasable upon the exercise of a Right.  Each of the Rights outstanding
after the adjustment in the number of Rights shall be exercisable for the
number of one one-thousandth of a share of Preferred Stock for which a Right
was exercisable immediately prior to such adjustment.  Each Right held of
record prior to such adjustment of the number of Rights shall become that
number of Rights (calculated to the nearest 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, indicating the record date for the
adjustment, and, if known at the time, the amount of the adjustment





                                       27
<PAGE>   31
to be made.  This record date may be the date on which the Purchase Price is
adjusted or any day thereafter, but, if the Rights Certificates have been
issued, shall be at least ten (10) days later than the date of the public
announcement.  If Rights Certificates have been issued, upon each adjustment of
the number of Rights pursuant to this Section 11(i), the Company shall, as
promptly as practicable, cause to be distributed to holders of record of Rights
Certificates on such record date Rights Certificates evidencing, subject to
Section 14 hereof, the additional Rights to which such holders shall be
entitled as a result of such adjustment, or, at the option of the Company,
shall cause to be distributed to such holders of record in substitution and
replacement for the Rights Certificates held by such holders prior to the date
of adjustment, and upon surrender thereof, if required by the Company, new
Rights Certificates evidencing all the Rights to which such holders shall be
entitled after such adjustment.  Rights Certificates so to be distributed shall
be issued, executed and countersigned in the manner provided for herein (and
may bear, at the option of the Company, the adjusted Purchase Price) and shall
be registered in the names of the holders of record of Rights Certificates on
the record date specified in the public announcement.

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

                          (k)  Before taking any action that would cause an
adjustment reducing the Purchase Price below the then stated value, if any, of
the number of one one-thousandth of a share of Preferred Stock 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 such number of one
one-thousandth of a share of Preferred Stock at such adjusted Purchase Price.





                                       28
<PAGE>   32
                          (l)  In any case in which this Section 11 shall
require that an adjustment in the Purchase Price be made effective as of a
record date for a specified event, the Company may elect to defer until the
occurrence of such event the issuance to the holder of any Right exercised
after such record date the number of one one-thousandth of a share of Preferred
Stock and other capital stock or securities of the Company, if any, issuable
upon such exercise over and above the number of one one-thousandth of a share
of Preferred Stock and other capital stock or securities of the Company, if
any, issuable upon such exercise on the basis of the Purchase Price in effect
prior to such adjustment; provided, however, that the Company shall deliver to
such holder a due bill or other appropriate instrument evidencing such holder's
right to receive such additional shares (fractional or otherwise) or securities
upon the occurrence of the event requiring such adjustment.

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

                          (n)  The Company covenants and agrees that, except as
permitted by Section 13(d) hereof, it shall not, at any time after the
Distribution Date, (i) consolidate with any other Person (other than a
Subsidiary of the Company in a transaction which complies with Section 11(o)
hereof), (ii) merge with or into any other Person (other than a Subsidiary of
the Company in a transaction which complies with Section 11(o) hereof), or
(iii) sell or transfer (or permit any Subsidiary to sell or transfer), in one
transaction, or a series of related





                                       29
<PAGE>   33
transactions, assets or earning power aggregating more than 50% of the assets
or earning power of the Company and its Subsidiaries (taken as a whole) to any
other Person or Persons (other than the Company and/or any of its Subsidiaries
in one or more transactions each of which complies with Section 11(o) hereof),
if (x) at the time of or immediately after such consolidation, merger or sale
there are any rights, warrants or other instruments or securities outstanding
or agreements in effect which would substantially diminish or otherwise
eliminate the benefits intended to be afforded by the Rights or (y) prior to,
simultaneously with or immediately after such consolidation, merger or sale,
the stockholders of the Person who constitutes, or would constitute, the
"Principal Party" for purposes of Section 13(a) hereof shall have received a
distribution of Rights previously owned by such Person or any of its Affiliates
and Associates.

                          (o)  The Company covenants and agrees that, after the
Distribution Date, it will not, except as permitted by Section 13(d), Section
23 or Section 27 hereof, take (or permit any Subsidiary to take) any action if
at the time such action is taken it is reasonably foreseeable that such action
will diminish substantially or otherwise eliminate the benefits intended to be
afforded by the Rights.

                          (p)  Anything in this Agreement to the contrary
notwithstanding, in the event that the Company shall at any time after the
Rights Dividend Declaration Date and prior to the Distribution Date (i) declare
a dividend on the outstanding shares of Common Stock payable in shares of
Common Stock, (ii) subdivide the outstanding shares of Common Stock, or (iii)
combine the outstanding shares of Common Stock into a smaller number of shares,
the number of Rights associated with each share of Common Stock then
outstanding, or issued or delivered thereafter but prior to the Distribution
Date, shall be proportionately adjusted so that the number of Rights thereafter
associated with each share of Common Stock following any such event shall equal
the result obtained by multiplying the number of Rights associated with each
share of Common Stock immediately prior to such event by a fraction the
numerator which shall be the total number of shares of Common Stock outstanding
immediately prior to the occurrence of the event and the denominator of which
shall be the total number of shares





                                       30
<PAGE>   34
of Common Stock outstanding immediately following the occurrence of such event.

                 Section 12.  Certificate of Adjusted Purchase Price or Number
of Shares.  Whenever an adjustment is made as provided in Section 11 and
Section 13 hereof, the Company shall (a) promptly prepare a certificate setting
forth such adjustment and a brief statement of the facts accounting for such
adjustment, (b) promptly file with the Rights Agent, and with each transfer
agent for the Preferred Stock and the Common Stock, a copy of such certificate,
and (c) if a Distribution Date has occurred, mail a brief summary thereof to
each holder of a Rights Certificate in accordance with Section 26 hereof.  The
Rights Agent shall be fully protected in relying on any such certificate and on
any adjustment therein contained.

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

                          (a)  In the event that, following the Stock
Acquisition Date, directly or indirectly, (x) the Company shall consolidate
with, or merge with and into, any other Person (other than a Subsidiary of the
Company in a transaction which complies with Section 11(o) hereof), and the
Company shall not be the continuing or surviving corporation of such
consolidation or merger, (y) any Person (other than a Subsidiary of the Company
in a transaction which complies with Section 11(o) hereof) shall consolidate
with, or merge with or into, the Company, and the Company shall be the
continuing or surviving corporation of such consolidation or merger and, in
connection with such consolidation or merger, all or part of the outstanding
shares of Common Stock shall be changed into or exchanged for stock or other
securities of any other Person or cash or any other property, or (z) the
Company shall sell or otherwise transfer (or one or more of its Subsidiaries
shall sell or otherwise transfer), in one transaction or a series of related
transactions, assets, earning power or cash flow aggregating more than 50% of
the assets or earning power of the Company and its Subsidiaries (taken as a
whole) to any Person or Persons (other than the Company or any Subsidiary of
the Company in one or more transactions each of which complies with Section
11(o) hereof), then, and in each such case (except as may be contemplated by
Section





                                       31
<PAGE>   35
13(d) hereof), proper provision shall be made so that:  (i) each holder of a
Right, except as provided in Section 7(e) hereof, shall thereafter have the
right to receive, upon the exercise thereof at the then current Purchase Price
in accordance with the terms of this Agreement, such number of validly
authorized and issued, fully paid, non-assessable and freely tradeable shares
of Common Stock of the Principal Party (as such term is hereinafter defined),
not subject to any liens, encumbrances, rights of first refusal or other
adverse claims, as shall be equal to the result obtained by (1) multiplying the
then current Purchase Price by the number of one one-thousandth of a share of
Preferred Stock for which a Right is exercisable immediately prior to the first
occurrence of a Section 13 Event (or, if a Section 11(a)(ii) Event has occurred
prior to the first occurrence of a Section 13 Event, multiplying the number of
such one one-thousandth of a share for which a Right was exercisable
immediately prior to the first occurrence of a Section 11(a)(ii) Event by the
Purchase Price in effect immediately prior to such first occurrence), and (2)
dividing that product (which, following the first occurrence of a Section 13
Event, shall be referred to as the "Purchase Price" for each Right and for all
purposes of this Agreement) by 50% of the Current Market Price (determined
pursuant to Section 11(d)(i) hereof) per share of the Common Stock of such
Principal Party on the date of consummation of such Section 13 Event; (ii) such
Principal Party shall thereafter be liable for, and shall assume, by virtue of
such Section 13 Event, all the obligations and duties of the Company pursuant
to this Agreement; (iii) the term "Company" shall thereafter be deemed to refer
to such Principal Party, it being specifically intended that the provisions of
Section 11 hereof shall apply only to such Principal Party following the first
occurrence of a Section 13 Event; (iv) such Principal Party shall take such
steps (including, but not limited to, the reservation of a sufficient number of
shares of its Common Stock) in connection with the consummation of any such
transaction as may be necessary to assure that the provisions hereof shall
thereafter be applicable, as nearly as reasonably may be, in relation to its
shares of Common Stock thereafter deliverable upon the exercise of the Rights;
and (v) the provisions of Section 11(a)(ii) hereof shall be of no effect
following the first occurrence of any Section 13 Event.

<PAGE>   36
                          (b)  "Principal Party" shall mean

                                  (i)  in the case of any transaction described
         in clause (x) or (y) of the first sentence of Section 13(a), the
         Person that is the issuer of any securities into which shares of
         Common Stock of the Company are converted in such merger or
         consolidation, and if no securities are so issued, the Person that is
         the other party to such merger or consolidation; and

                                  (ii)  in the case of any transaction
         described in clause (z) of the first sentence of Section 13(a), the
         Person that is the party receiving the greatest portion of the assets
         or earning power transferred pursuant to such transaction or
         transactions;

provided, however, that in any such case, (1) if the Common Stock of such
Person is not at such time and has not been continuously over the preceding
twelve (12) month period registered under Section 12 of the Exchange Act, and
such Person is a direct or indirect Subsidiary of another Person the Common
Stock of which is and has been so registered, "Principal Party" shall refer to
such other Person; and (2) in case such Person is a Subsidiary, directly or
indirectly, of more than one Person, the Common Stocks of two or more of which
are and have been so registered, "Principal Party" shall refer to whichever of
such Persons is the issuer of the Common Stock having the greatest aggregate
market value.

                          (c)  The Company shall not consummate any such
consolidation, merger, sale or transfer unless the Principal Party shall have a
sufficient number of authorized shares of its Common Stock which have not been
issued or reserved for issuance to permit the exercise in full of the Rights in
accordance with this Section 13 and unless prior thereto the Company and such
Principal Party shall have executed and delivered to the Rights Agent a
supplemental agreement providing for the terms set forth in paragraphs (a) and
(b) of this Section 13 and further providing that, as soon as practicable after
the date of any consolidation, merger or sale of assets mentioned in paragraph
(a) of this Section 13, the Principal Party will





                                       33
<PAGE>   37
                                  (i)  prepare and file a registration
         statement under the Act, with respect to the Rights and the securities
         purchasable upon exercise of the Rights on an appropriate form, and
         will use its best efforts to cause such registration statement to (A)
         become effective as soon as practicable after such filing and (B)
         remain effective (with a prospectus at all times meeting the
         requirements of the Act) until the Expiration Date; and

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

The provisions of this Section 13 shall similarly apply to successive mergers
or consolidations or sales or other transfers.  In the event that a Section 13
Event shall occur at any time after the occurrence of a Section 11(a)(ii)
Event, the Rights which have not theretofore been exercised shall thereafter
become exercisable in the manner described in Section 13(a).

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

             Section 14.  Fractional Rights and Fractional Shares.

                          (a)  The Company shall not be required to issue
fractions of Rights, except prior to the Distribution Date as provided in
Section 11(p) hereof, or to distribute Rights Certificates which evidence
fractional Rights.  In lieu of such fractional Rights, there shall be paid to
the registered holders of the Rights Certificates with regard to which such
fractional Rights would otherwise be issuable, an amount in cash equal to the
same fraction of the current market value of a whole Right.  For 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 fraction- al Rights would have been otherwise issuable.  The
closing price of the Rights 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 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 shares of Preferred Stock (other than fractions which are integral
multiples of one one-thousandth of a share of Preferred Stock) upon exer-





                                       35
<PAGE>   39
cise of the Rights or to distribute certificates which evidence fractional
shares of Preferred Stock (other than fractions which are integral multiples of
one one-thousandth of a share of Preferred Stock).  In lieu of fractional
shares of Preferred Stock that are not integral multiples of one one-thousandth
of a share of Preferred Stock, the Company may pay to the registered holders of
Rights Certificates at the time such Rights are exercised as herein provided an
amount in cash equal to the same fraction of the current market value of one
one-thousandth of a share of Preferred Stock.  For purposes of this Section
14(b), the current market value of one one-thousandth of a share of Preferred
Stock shall be one one-thousandth of the closing price of a share of Preferred
Stock (as determined pursuant to Section 11(d)(ii) hereof) for the Trading Day
immediately prior to the date of such exercise.

                          (c)  Following the occurrence of a Triggering Event,
the Company shall not be required to issue fractions of shares of Common Stock
upon exercise of the Rights or to distribute certificates which evidence
fractional shares of Common Stock.  In lieu of fractional shares of Common
Stock, the Company may pay to the registered holders of Rights Certificates at
the time such Rights are exercised as herein provided an amount in cash equal
to the same fraction of the current market value of one (1) share of Common
Stock.  For purposes of this Section 14(c), the current market value of one
share of Common Stock shall be the closing price of one share of Common Stock
(as determined pursuant to Section 11(d)(i) hereof) for the Trading Day
immediately prior to the date of such exercise.

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


                 Section 15.  Rights of Action.  All rights of action in
respect of this Agreement are vested in the respective registered holders of
the Rights Certificates (and, prior to the Distribution Date, the registered
holders of the Common Stock); and any registered holder of any Rights
Certificate (or, prior to the Distribution Date, of the Common Stock), without
the consent of the





                                       36
<PAGE>   40
Rights Agent or of the holder of any other Rights Certificate (or, prior to the
Distribution Date, of the Common Stock), may, in his own behalf and for his own
benefit, enforce, and may institute and maintain any suit, action or proceeding
against the Company to enforce, or otherwise act in respect of, his right to
exercise the Rights evidenced by such Rights Certificate in the manner provided
in such Rights Certificate and in this Agreement.  Without limiting the
foregoing or any remedies available to the holders of Rights, it is
specifically acknowledged that the holders of Rights would not have an adequate
remedy at law for any breach of this Agreement and shall be entitled to
specific performance of the obligations hereunder and injunctive relief against
actual or threatened violations of the obligations hereunder of any Person
subject to this Agreement.

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

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

                          (b)  after the Distribution Date, the Rights
Certificates are transferable only on the registry books of the Rights Agent if
surrendered at the principal office or offices of the Rights Agent designated
for such purposes, duly endorsed or accompanied by a proper instrument of
transfer and with the appropriate forms and certificates fully executed;

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





                                       37
<PAGE>   41
                          (d)  notwithstanding anything in this Agreement to
the contrary, neither the Company nor the Rights Agent shall have any liability
to any holder of a Right or other Person as a result of its inability to
perform any of its obligations under this Agreement by reason of any
preliminary or permanent injunction or other order, decree or ruling issued by
a court of competent jurisdiction or by a governmental, regulatory or
administrative agency or commission, or any statute, rule, regulation or
executive order promulgated or enacted by any governmental authority,
prohibiting or otherwise restraining performance of such obligation; provided,
however, the Company must use its best efforts to have any such order, decree
or ruling lifted or otherwise overturned as soon as possible.

                 Section 17.  Rights Certificate Holder Not Deemed a
Stockholder.  No holder, as such, of any Rights Certificate shall be entitled
to vote, receive dividends or be deemed for any purpose the holder of the
number of one one-thousandth of a share of Preferred Stock 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
Rights Certificate be construed to confer upon the holder of any Rights
Certificate, as such, any of the rights of a stockholder of the Company or any
right to vote for the election of directors or upon any matter submitted to
stockholders at any meeting thereof, or to give or withhold consent to any
corporate action, or to receive notice of meetings or other actions affecting
stockholders (except as provided in Section 25 hereof), or to receive dividends
or subscription rights, or otherwise, until the Right or Rights evidenced by
such Rights Certificate shall have been exercised in accordance with the
provisions hereof.

                 Section 18.  Concerning the Rights Agent.

                          (a)  The Company agrees to pay to the Rights Agent
reasonable compensation for all services rendered by it hereunder and, from
time to time, on demand of the Rights Agent, its reasonable expenses and
counsel fees and disbursements and other disbursements incurred in the
administration and execution of this Agreement and the exercise and performance
of its duties hereunder.  The Company also agrees to indemnify the





                                       38
<PAGE>   42
Rights Agent for, and to hold it harmless against, any loss, liability, or
expense, incurred without negligence, bad faith or willful misconduct on the
part of the Rights Agent, for anything done or omitted by the Rights Agent in
connection with the acceptance and administration of this Agreement, including
the costs and expenses of defending against any claim of liability in the
premises.

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

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

                          (a)  Any corporation into which the Rights Agent or
any successor Rights Agent may be merged or with which it may be consolidated,
or any corporation resulting from any merger or consolidation to which the
Rights Agent or any successor Rights Agent shall be a party, or any corporation
succeeding to the corporate trust or stockholder 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, however,
that such corporation would be eligible for appointment as a successor Rights
Agent under the provisions of Section 21 hereof.  In case at the time such
successor Rights Agent shall succeed to the agency created by this Agreement,
any of the Rights Certificates shall have been countersigned but not delivered,
any such successor Rights Agent may adopt the countersignature of a predecessor
Rights Agent and deliver such Rights Certificates so countersigned; and in case
at that time any of the Rights Certificates shall not have been countersigned,
any successor Rights Agent may countersign such Rights Certificates either in
the name of the predecessor or in the name of





                                       39
<PAGE>   43
the successor Rights Agent; and in all such cases such Rights Certificates
shall have the full force provided in the Rights Certificates and in this
Agreement.

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

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

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

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





                                       40
<PAGE>   44
provisions of this Agreement in reliance upon such certificate.

                          (c)  The Rights Agent shall be liable hereunder only
for its own negligence, bad faith or willful misconduct.

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

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





                                       41
<PAGE>   45
                          (g)  The Rights Agent is hereby authorized and
directed to accept instructions with respect to the performance of its duties
hereunder from the Chairman of the Board, the President, any Vice President,
the Secretary, any Assistant Secretary, the Treasurer or any Assistant
Treasurer of the Company, and to apply to such officers for advice or
instructions in connection with its duties, and it shall not be liable for any
action taken or suffered to be taken by it in good faith in accordance with
instructions of any such officer.

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

                          (i)  The Rights Agent may execute and exercise any of
the rights or powers hereby vested in it or perform any duty hereunder either
itself or by or through its attorneys or agents, and the Rights Agent shall not
be answerable or accountable for any act, 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, however, reasonable care was
exercised in the selection and continued employment thereof.

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

                          (k)  If, with respect to any Right Certificate
surrendered to the Rights Agent for exercise or transfer, the certificate
attached to the form of assignment or form of election to purchase, as the case
may be, has either not been completed or indicates an affir-





                                       42
<PAGE>   46
mative response to clause 1 and/or 2 thereof, the Rights Agent shall not take
any further action with respect to such requested exercise of transfer without
first consulting with the Company.

                 Section 21.  Change of Rights Agent.  The Rights Agent or any
successor Rights Agent may resign and be discharged from its duties under this
Agreement upon thirty (30) days' notice in writing mailed to the Company, and
to each transfer agent of the Common Stock and Preferred Stock, by registered
or certified mail, and to the holders of the Rights Certificates by first-class
mail.  The Company may remove the Rights Agent or any successor Rights Agent
upon thirty (30) days' notice in writing, mailed to the Rights Agent or
successor Rights Agent, as the case may be, and to each transfer agent of the
Common Stock and Preferred Stock, by registered or certified mail, and to the
holders of the Rights 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 thirty (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 Rights Certificate (who shall, with such notice, submit his
Rights Certificate for inspection by the Company), then any registered holder
of any Rights Certificate may apply to any court of competent jurisdiction for
the appointment of a new Rights Agent.  Any successor Rights Agent, whether
appointed by the Company or by such a court, shall be a corporation organized
and doing business under the laws of the United States or of any State thereof,
in good standing, which is authorized under such laws to exercise corporate
trust powers and is subject to supervision or examination by federal or state
authority and which has at the time of its appointment as Rights Agent a
combined capital and surplus of at least $100,000,000.  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





                                       43
<PAGE>   47
purpose.  Not later than the effective date of any such appointment, the
Company shall file notice thereof in writing with the predecessor Rights Agent
and each transfer agent of the Common Stock and the Preferred Stock, and mail a
notice thereof in writing to the registered holders of the Rights Certificates.
Failure to give any notice provided for in this Section 21, however, or any
defect therein, shall not affect the legality or validity of the resignation or
removal of the Rights Agent or the appointment of the successor Rights Agent,
as the case may be.

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

                 Section 23.  Redemption and Termination.

                          (a)  The Board of Directors of the Company may, at
its option, at any time prior to the earlier of (i) the close of business on
the tenth Business Day following the Stock Acquisition Date (or, if the Stock
Acquisition Date shall have occurred prior to the Record Date, the close of
business on the tenth day following the Record Date), or (ii) the Final
Expiration Date, redeem all but not less than all the then outstanding Rights
at a redemption price of $0.01 per Right, as such amount may be appropriately
adjusted to reflect any stock split, stock dividend or similar transaction
occurring after the date hereof (such redemption price being hereinafter
referred to as the "Redemption Price").  Notwithstanding anything contained in
this Agreement to the contrary, the Rights shall not be exercisable after the
first occurrence of a Section 11(a)(ii) Event until such time as the Company's
right of redemption hereunder has expired.  The Company may, at its option, pay
the Redemption Price in cash, shares of Common Stock (based on the Current
Market Price, as defined in Section 11(d)(i) hereof, of the Common Stock at the
time of redemption) or any other form of consideration deemed appropriate by
the Board of Directors.

                          (b)  Immediately upon the action of the Board of
Directors of the Company ordering the redemption of the Rights, evidence of
which shall have been filed with the Rights Agent and without any further
action and without any notice, the right to exercise the Rights will terminate
and the only right thereafter of the holders of Rights shall be to receive the
Redemption Price for each Right so held.  Promptly after the action of the
Board of Directors ordering the redemption of the Rights, the Company shall
give notice of such redemption to the Rights Agent and the holders of the then
outstanding Rights by mailing such notice to all such holders at each holder's
last address as it appears upon the registry books of the Rights Agent or,
prior to the Distribution Date, on the registry books of the transfer agent for
the Common Stock.  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.

<PAGE>   49
                 Section 24.  Exchange.  (a) The Board 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 7(e) hereof) for
shares of Common Stock at an exchange ratio of one share of Common Stock per
Right, appropriately adjusted to reflect any stock split, stock dividend or
similar transaction occurring after the date hereof (such exchange ratio being
hereinafter referred to as the "Exchange Ratio").  Notwithstanding the
foregoing, the Board 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 Stock for or pursuant to the terms of any such plan), together
with all Affiliates and Associates of such Person, becomes the Beneficial Owner
of fifty percent (50%) or more of the Common Stock then outstanding.

                          (b)     Immediately upon the action of the Board
ordering the exchange of any Rights pursuant to subsection (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 shares of Common Stock equal to the
number of such Rights held by such holder multiplied by the Exchange Ratio. The
Company shall promptly give public notice of any such exchange; provided,
however, that the failure to give, or any defect in, such notice shall not
affect the validity of such exchange.  The Company promptly shall mail a notice
of any such exchange to all of the holders of such Rights at their last
addresses as they appear upon the registry books of the Rights Agent.  Any
notice which is mailed in the manner herein provided shall be deemed given,
whether or not the holder receives the notice.  Each such notice of exchange
will state the method by which the exchange of the Common Stock 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 7(e) hereof) held by each holder of Rights.





                                       46
<PAGE>   50
                          (c)  In any exchange pursuant to this Section 24, the
Company, at its option, may substitute shares of Preferred Stock (or Equivalent
Preferred Stock, as such term is defined in paragraph (b) of Section 11 hereof)
for shares of Common Stock exchangeable for rights, at the initial rate of one
one-thousandth of a share of Preferred Stock (or Equivalent Preferred Stock)
for each share of Common Stock, as appropriately adjusted to reflect
adjustments in the voting rights of the Preferred Stock pursuant to Section 3
of the Certificate of Designation, Preferences and Rights of the Series A
Junior Participating Preferred Stock attached hereto as Exhibit A, so that the
fraction of a share of Preferred Stock delivered in lieu of each share of
Common Stock shall have the same voting rights as one share of Common Stock.

                          (d)  In the event that there shall not be sufficient
shares of Common Stock 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 shares of Common Stock for issuance upon exchange of the Rights.

                          (e)  The Company shall not be required to issue
fractions of shares of Common Stock or to distribute certificates which
evidence fractional shares of Common Stock.  In lieu of such fractional shares
of Common Stock, there shall be paid to the registered holders of the Right
Certificates with regard to which such fractional share of Common Stock would
otherwise be issuable, an amount in cash equal to the same fraction of the
current market value of a whole share of Common Stock.  For the purposes of
this subsection (e), the current market value of a whole share of Common Stock
shall be the closing price of a share of Common Stock (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 propose, at any time
after the Distribution Date, (i) to pay any dividend payable in stock of any
class to the holders of Preferred Stock or to make any other distribution to
the





                                       47
<PAGE>   51
holders of Preferred Stock (other than a regular quarterly cash dividend out of
earnings or retained earnings of the Company), or (ii) to offer to the holders
of Preferred Stock rights or warrants to subscribe for or to purchase any
additional shares of Preferred Stock or shares of stock of any class or any
other securities, rights or options, or (iii) to effect any reclassification of
its Preferred Stock (other than a reclassification involving only the
subdivision of outstanding shares of Preferred Stock), or (iv) to effect any
consolidation or merger into or with any other Person (other than a Subsidiary
of the Company in a transaction which complies with Section 11(o) hereof), 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 transaction or a
series of related transactions, of more than 50% of the assets or earning power
of the Company and its Subsidiaries (taken as a whole) to any other Person or
Persons (other than the Company and/or any of its Subsidiaries in one or more
transactions each of which complies with Section 11(o) hereof), or (v) to
effect the liquidation, dissolution or winding up of the Company, then, in each
such case, the Company shall give to each holder of a Rights Certificate, to
the extent feasible and in accordance with Section 26 hereof, a notice of such
proposed action, which shall specify the record date for the purposes of such
stock dividend 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 shares of Preferred Stock, if any such date is to
be fixed, and such notice shall be so given in the case of any action covered
by clause (i) or (ii) above at least twenty (20) days prior to the record date
for determining holders of the shares of Preferred Stock for purposes of such
action, and in the case of any such other action, at least twenty (20) days
prior to the date of the taking of such proposed action or the date of
participation therein by the holders of the shares of Preferred Stock whichever
shall be the earlier.

                          (b)  In case any of the events set forth in Section
11(a)(ii) hereof shall occur, then, in any such case, (i) the Company shall as
soon as practicable thereafter give to each holder of a Rights Certificate, to
the extent feasible and in accordance with Section 26





                                       48
<PAGE>   52
hereof, a notice of the occurrence of such event, which shall specify the event
and the consequences of the event to holders of Rights under Section 11(a)(ii)
hereof, and (ii) all references in the preceding paragraph to Preferred Stock
shall be deemed thereafter to refer to Common Stock and/or, if appropriate,
other securities.

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

first-class mail, postage prepaid, addressed to such holder at the address of
such holder as shown on the registry books of the Company.

                 Section 27.  Supplements and Amendments.  Prior to the
Distribution Date, the Company and the Rights Agent shall, if the Company so
directs, supplement or amend any provision of this Agreement without the ap-

proval of any holders of certificates representing shares of Common Stock.
From and after the Distribution Date, the Company and the Rights Agent shall,
if the Company so directs, supplement or amend this Agreement without the
approval of any holders of Rights Certificates in order (i) to cure any
ambiguity, (ii) to correct or supplement any provision contained herein which
may be defective or inconsistent with any other provisions herein, (iii) to
shorten or lengthen any time period hereunder or (iv) to change or supplement
the provisions hereunder in any manner which the Company may deem necessary or
desirable and which shall not adversely affect the interests of the holders of

Associate of an Acquiring Person); provided, from and after the Distribution
Date, this Agreement may not be supplemented or amended to lengthen, pursuant
to clause (iii) of this sentence, (A) a time period relating to when the Rights
may be redeemed at such time as the Rights are not then redeemable, or (B) any
other time period unless such lengthening is for the purpose of protecting,
enhancing or clarifying the rights of, and/or the benefits to, the holders of
Rights.  Upon the delivery of a certificate from an appropriate officer of the
Company which states that the proposed supplement or amendment is in compliance
with the terms of this Section 27, the Rights Agent shall execute such
supplement or amendment.  Prior to the Distribution Date, the interests of the
holders of Rights shall be deemed coincident with the interests of the holders
of Common Stock.

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

                 Section 29.  Determinations and Actions by the Board of
Directors, etc.  For all purposes of this Agreement, any calculation of the

Rules and Regulations under the Exchange Act.  The Board of Directors of the
Company





                                       50
<PAGE>   54
shall have the exclusive power and authority to administer this Agreement and
to exercise all rights and powers specifically granted to the Board or to the
Company, or as may be necessary or advisable in the administration of this
Agreement, including, without limitation, the right and power to (i) interpret
the provisions of this Agreement, and (ii) make all determinations deemed
necessary or advisable for the administration of this Agreement (including a
determination to redeem or not redeem the Rights or to amend the Agreement).
All such actions, calculations, interpretations and determinations (including,
for purposes of clause (y) below, all omissions with respect to the foregoing)
which are done or made by the Board in good faith, shall (x) be final,
conclusive and binding on the Company, the Rights Agent, the holders of the
Rights and all other parties, and (y) not subject the Board to any liability to
the holders of the Rights.

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

                 Section 31.  Severability.  If any term, provision, covenant
or restriction of this Agreement is held by a court of competent jurisdiction
or other authority to be invalid, void or unenforceable, the remainder of the
terms, provisions, covenants and restrictions of this Agreement shall remain in
full force and effect and shall in no way be affected, impaired or invalidated;
provided, however, that notwithstanding anything in this Agreement to the
contrary, if any such term, provision, covenant or restriction is held by such
court or authority to be invalid, void or unenforceable and the Board of
Directors of the Company determines in its good faith judgment that severing
the invalid language from this Agreement would adversely affect the purpose or
effect of this Agreement, the right of redemption set forth in Section 23
hereof shall be





                                       51
<PAGE>   55
reinstated and shall not expire until the close of business on the tenth
Business Day following the date of such determination by the Board of
Directors.

                 Section 32.  Governing Law.  This Agreement, each Right and
each Rights Certificate issued hereunder shall be deemed to be a contract made
under the laws of the State of Delaware and for all purposes shall be governed
by and construed in accordance with the laws of such State applicable to
contracts made and to be performed entirely within such State.

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

                 Section 34.  Descriptive Headings.  Descriptive headings of
the several Sections of this Agreement are inserted for convenience only and

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


                 The undersigned officer of Helmerich & Payne, Inc., a
corporation organized and existing under the General Corporation Law of the
State of Delaware, in accordance with the provisions of Section 103 thereof,
DOES HEREBY CERTIFY:

                 That pursuant to the authority conferred upon the Board of
Directors by the Restated Certificate of Incorporation of the said Corporation,
the said Board of Directors on January 8, 1996 adopted the following resolution
creating a series of 60,000 shares of Preferred Stock designated as Series A
Junior Participating Preferred Stock:

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

                 Section 1.  Designation and Amount.  The shares of such series
shall be designated as "Series A Junior Participating Preferred Stock" and the
number of shares constituting such series shall be 60,000.

                 Section 2.  Dividends and Distributions.





<PAGE>   57
                 (A)  The holders of shares of Series A Junior Participating
Preferred Stock shall be entitled to receive, when, as and if declared by the
Board of Directors out of funds legally available for the purpose, quarterly
dividends payable in cash on the last day of March, June, September and
December 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 A
Junior Participating Preferred Stock, in an amount per share (rounded to the
nearest cent) equal to the greater of (a) $125 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, par value $0.10 per share, of the Corporation (the "Common
Stock") since the immediately preceding Quarterly Dividend Payment Date, or,
with respect to the first Quarterly Dividend Payment Date, since the first
issuance of any share or fraction of a share of Series A Junior Participating
Preferred Stock.  In the event the Corporation shall at any time after January
8, 1996 (the "Rights Declaration Date") (i) declare any dividend on Common
Stock payable in shares of Common Stock, (ii) subdivide the outstanding Common
Stock, or (iii) combine the outstanding Common Stock into a smaller number of
shares, then in each such case the amount to which holders of shares of Series
A Junior Participating 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 A Junior Participating Preferred Stock as provided in Paragraph
(A) above immediately after it declares a dividend or distribution on the
Common Stock (other than a dividend payable in shares of Common Stock);
provided that, in the event no dividend or distribution shall have been
declared on the Common Stock during the





                                      A-2
<PAGE>   58
period between any Quarterly Dividend Payment Date and the next subsequent
Quarterly Dividend Payment Date, a dividend of $125 per share on the Series A
Junior Participating Preferred Stock shall nevertheless be payable on such
subsequent Quarterly Dividend Payment Date.

                 (C)  Dividends shall begin to accrue and be cumulative on
outstanding shares of Series A Junior Participating Preferred Stock from the
Quarterly Dividend Payment Date next preceding the date of issue of such shares
of Series A Junior Participating Preferred Stock, unless the date of issue of
such shares is prior to the record date for the first Quarterly Dividend
Payment Date, in which case dividends on such shares shall begin to accrue from
the date of issue of such shares, or unless the date of issue is a Quarterly
Dividend Payment Date or is a date after the record date for the determination
of holders of shares of Series A Junior Participating Preferred Stock entitled
to receive a quarterly dividend and before such Quarterly Dividend Payment
Date, in either of which events such dividends shall begin to accrue and be
cumulative from such Quarterly Dividend Payment Date.  Accrued but unpaid
dividends shall not bear interest.  Dividends paid on the shares of Series A
Junior Participating 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 A Junior Participating Preferred
Stock entitled to receive payment of a dividend or distribution declared
thereon, which record date shall be no more than 30 days prior to the date
fixed for the payment thereof.

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

                 (A)  Subject to the provision for adjustment hereinafter set
forth, each share of Series A Junior Participating 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 after the Rights Declaration Date (i) declare any dividend on Common Stock
payable in shares of Common Stock, (ii) subdivide the outstanding Common Stock,
or (iii) combine the outstanding Common Stock into a smaller





                                      A-3
<PAGE>   59
number of shares, then in each such case the number of votes per share to which
holders of shares of Series A Junior Participating 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 or by law, the
holders of shares of Series A Junior Participating Preferred Stock and the
holders of shares of Common Stock shall vote together as one class on all
matters submitted to a vote of stockholders of the Corporation.

                 (C)  (i)  If at any time dividends on any Series A Junior
         Participating Preferred Stock shall be in arrears in an amount equal
         to six (6) quarterly dividends thereon, the occurrence of such
         contingency shall mark the beginning of a period (herein called a
         "default period") which shall extend until such time when all accrued
         andunpaid dividends for all previous quarterly dividend periods and
         for the current quarterly dividend period on all shares of Series A
         Junior Participating Preferred Stock then outstanding shall have been
         declared and paid or set apart for payment.  During each default
         period, all holders of Preferred Stock (including holders of the
         Series A Junior Participating Preferred Stock) with dividends in
         arrears in an amount equal to six (6) quarterly dividends thereon,
         voting as a class, irrespective of series, shall have the right to
         elect two (2) directors.

                          (ii)  During any default period, such voting right of
         the holders of Series A Junior Participating Preferred Stock may be
         exercised initially at a special meeting called pursuant to
         subparagraph (iii) of this Section 3(C) or at any annual meeting of
         stockholders, and thereafter at annual meetings of stockholders,
         provided that such voting right shall not be exercised unless the
         holders of ten percent (10%) in number of shares of Preferred Stock
         outstanding shall be present in person or by proxy.  The absence of a





                                      A-4
<PAGE>   60
         quorum of the holders of Common Stock shall not affect the exercise by
         the holders of Preferred Stock of such voting right.  At any meeting
         at which the holders of Preferred Stock shall exercise such voting
         right initially during an existing default period, they shall have the
         right, voting as a class, to elect directors to fill such vacancies,
         if any, in the Board of Directors as may then exist up to two (2)
         directors or, if such right is exercised at an annual meeting, to
         elect two (2) directors.  If the number which may be so elected at any
         special meeting does not amount to the required number, the holders of
         the Preferred Stock shall have the right to make such increase in the
         number of directors as shall be necessary to permit the election by
         them of the required number.  After the holders of the Preferred Stock
         shall have exercised their right to elect directors in any default
         period and during the continuance of such period, the number of
         directors shall not be increased or decreased except by vote of the
         holders of Preferred Stock as herein provided or pursuant to the
         rights of any equity securities ranking senior to or pari passu with
         the Series A Junior Participating Preferred Stock.

                          (iii)  Unless the holders of Preferred Stock shall,
         during an existing default period, have previously exercised their
         right to elect directors, the Board of Directors may order, or any
         stockholder or stockholders owning in the aggregate not less than ten
         percent (10%) of the total number of shares of Preferred Stock
         outstanding, irrespective of series, may request, the calling of
         special meeting of the holders of Preferred Stock, which meeting shall
         thereupon be called by the President, a Vice-President or the
         Secretary of the Corporation.  Notice of such meeting and of any
         annual meeting at which holders of Preferred Stock are entitled to
         vote pursuant to this Paragraph (C)(iii) shall be given to each holder
         of record of Preferred Stock by mailing a copy of such notice to him
         or her at his or her last address as the same appears on the books of
         the Corporation.  Such meeting shall be called for a time not earlier
         than 20 days and not later than 60 days after such order or request or
         in default of the calling of such meeting within 60 days after such
         order or request, such meeting may be called on similar notice by any
         stockholder or





                                      A-5
<PAGE>   61
         stockholders owning in the aggregate not less than ten percent (10%)
         of the total number of shares of Preferred Stock outstanding.
         Notwithstanding the provisions of this Paragraph (C)(iii), no such
         special meeting shall be called during the period within 60 days
         immediately preceding the date fixed for the next annual meeting of
         the stockholders.

                          (iv)  In any default period, the holders of Common
         Stock, and other classes of stock of the Corporation if applicable,
         shall continue to be entitled to elect the whole number of directors
         until the holders of Preferred Stock shall have exercised their right
         to elect two (2) directors voting as a class, after the exercise of
         which right (x) the directors so elected by the holders of Preferred
         Stock shall continue in office until their successors shall have been
         elected by such holders or until the expiration of the default period,
         and (y) any vacancy in the Board of Directors may (except as provided
         in Paragraph (C)(ii) of this Section 3) be filled by vote of a
         majority of the remaining directors theretofore elected by the holders
         of the class of stock which elected the Director whose office shall
         have become vacant.  References in this Paragraph (C) to directors
         elected by the holders of a particular class of stock shall include
         directors elected by such directors to fill vacancies as provided in
         clause (y) of the foregoing sentence.

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

<PAGE>   62
                 (D)  Except as set forth herein, holders of Series A Junior
Participating 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 A Junior Participating Preferred Stock as
provided in Section 2 are in arrears, thereafter and until all accrued and
unpaid dividends and distributions, whether or not declared, on shares of
Series A Junior Participating Preferred Stock outstanding shall have been paid
in full, the Corporation shall not

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

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

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





                                      A-7
<PAGE>   63
                                  (iv)  purchase or otherwise acquire for
         consideration any shares of Series A Junior Participating Preferred
         Stock, or any shares of stock ranking on a parity with the Series A
         Junior Participating Preferred Stock, except in accordance with a
         purchase offer made in writing or by publication (as determined by the
         Board of Directors) to all holders of such shares upon such terms as
         the Board of Directors, after consideration of the respective annual
         dividend rates and other relative rights and preferences of the
         respective series and classes, shall determine in good faith will
         result in fair and equitable treatment among the respective series or
         classes.

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

                 Section 5.  Reacquired Shares.  Any shares of Series A Junior
Participating Preferred Stock purchased or otherwise acquired by the
Corporation in any manner whatsoever shall be retired and cancelled promptly
after the acquisition thereof.  All such shares shall upon their cancellation
become authorized but unissued shares of Preferred Stock and may be reissued as
part of a new series of Preferred Stock to be created by resolution or
resolutions of the Board of Directors, subject to the conditions and
restrictions on issuance set forth herein.

                 Section 6.  Liquidation, Dissolution or Winding Up.  (A)  Upon
any liquidation (voluntary or otherwise), dissolution or winding up of the
Corporation, no distribution shall be made to the holders of shares of stock
ranking junior (either as to dividends or upon liquidation, dissolution or
winding up) to the Series A Junior Participating Preferred Stock unless, prior
thereto, the holders of shares of Series A Junior Participating 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 (the "Series A Liquidation Preference").  Following the
payment of the full amount of the Series A Liquidation Preference, no
additional distributions shall be made to the holders of shares of Series A
Junior Participating Preferred Stock unless, prior





                                      A-8
<PAGE>   64
thereto, the holders of shares of Common Stock shall have received an amount
per share (the "Common Adjustment") equal to the quotient obtained by dividing
(i) the Series A Liquidation Preference by (ii) 1,000 (as appropriately
adjusted as set forth in subparagraph (C) below to reflect such events as stock
splits, stock dividends and recapitaliza-tions with respect to the Common
Stock) (such number in clause (ii), the "Adjustment Number").  Following the
payment of the full amount of the Series A Liquidation Preference and the
Common Adjustment in respect of all outstanding shares of Series A Junior
Participating Preferred Stock and Common Stock, respectively, holders of Series
A Junior Participating Preferred Stock and holders of shares of Common Stock
shall receive their ratable and proportionate share of the remaining assets to
be distributed in the ratio of the Adjustment Number to 1 with respect to such
Preferred Stock and Common Stock, on a per share basis, respectively.

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

                 (C)  In the event the Corporation shall at any time after the
Rights Declaration Date (i) declare any dividend on Common Stock payable in
shares of Common Stock, (ii) subdivide the outstanding Common Stock, or (iii)
combine the outstanding Common Stock into a smaller number of shares, then in
each such case the Adjustment Number in effect immediately prior to such event
shall be adjusted by multiplying such Adjustment Number by a fraction the
numerator of which is the number of shares of Common Stock outstanding
immediately after such event and the denominator of which is the number of
shares of Common Stock that were outstanding immediately prior to such event.

                 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





                                     A-9
<PAGE>   65
such case the shares of Series A Junior Participating Preferred Stock shall at
the same time be similarly exchanged or changed in 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
after the Rights Declaration Date (i) declare any dividend on Common Stock
payable in shares of Common Stock, (ii) subdivide the outstanding Common Stock,
or (iii) combine the outstanding Common Stock into a smaller number of shares,
then in each such case the amount set forth in the preceding sentence with
respect to the exchange or change of shares of Series A Junior Participating
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.  No Redemption.  The shares of Series A Junior
Participating Preferred Stock shall not be redeemable.

                 Section 9.  Amendment.  The Restated Certificate of
Incorporation of the Corporation shall not be further amended in any manner
which would materially alter or change the powers, preferences or special
rights of the Series A Junior Participating Preferred Stock so as to affect
them adversely without the affirmative vote of the holders of a majority or
more of the outstanding shares of Series A Junior Participating Preferred
Stock, voting separately as a class.

                 Section 10.  Fractional Shares.  Series A Junior Participating
Preferred Stock may be issued in fractions of a share which shall entitle the
holder, in proportion to such holders fractional shares, to exercise voting
rights, receive dividends, participate in distributions and to have the benefit
of all other rights of holders of Series A Junior Participating Preferred
Stock.

Agreement"), between Helmerich & Payne, Inc., a Delaware corporation (the
"Company"), and Liberty Bank and Trust Company of Oklahoma City, N.A. (the

its successors as Rights Agent, one one-thousandth of a fully paid,
non-assessable share of Series A Junior Partici- pating Preferred Stock (the
"Preferred Stock") of the Company, at a purchase price of $90 per one
one-thousandth of a share (the "Purchase Price"), upon presentation and
surrender of this Rights Certificate with the Form of Election to Purchase and
related Certificate duly executed.  The number of Rights evidenced by this
Rights Certificate (and the number of shares which may be purchased upon
exercise thereof) set forth above, and the Purchase Price per share set forth
above, are the number and Purchase Price as of January 8, 1996 based on the
Preferred Stock as constituted at such date.  The Company reserves the right to
require prior to the occurrence of a Triggering Event (as such term is defined
in the Rights Agreement) that a number of Rights be exercised so that only
whole shares of Preferred Stock will be issued.

                 Upon the occurrence of a Section 11(a)(ii) Event (as such term
is defined in the Rights Agreement), if the Rights evidenced by this Rights
Certificate are beneficially owned by (i) an Acquiring Person or an Affiliate
or Associate of any such Acquiring Person (as such terms are defined in the
Rights Agreement), (ii) a transferee of any such Acquiring Person, Associate or
Affiliate, or (iii) under certain circumstances specified in the Rights
Agreement, a transferee of a person who, after such transfer, became an
Acquiring Person, or an Affiliate or Associate of an Acquiring Person, such
Rights shall become null and void and no holder hereof shall have any right
with respect to such Rights from and after the occurrence of such Section
11(a)(ii) Event.

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

                 This Rights Certificate is subject to all of the terms,
provisions and conditions of the Rights Agreement, which terms, provisions and
conditions are hereby incorporated herein by reference and made a part hereof
and to which Rights Agreement reference is hereby made for a full description
of the rights, limitations of rights, obligations, duties and immunities
hereunder of the Rights Agent, the Company and the holders of the Rights
Certificates, which limitations of rights include the temporary suspen-





                                      B-2
<PAGE>   69
sion of the exercisability of such Rights under the specific circumstances set
forth in the Rights Agreement.  Copies of the Rights Agreement are on file at
the above-mentioned office of the Rights Agent and are also available upon
written request to the Rights Agent.

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

                 Subject to the provisions of the Rights Agreement, the Rights
evidenced by this Certificate may be redeemed by the Company at its option at a
redemption price of $0.01 per Right at any time prior to the earlier of the
close of business on (i) the tenth business day following the Stock Acquisition
Date (as such time period may be extended pursuant to the Rights Agreement),
and (ii) the Final Expiration Date.  In addition, the Rights may be exchanged,
in whole or in part, for shares of the Common Stock, or shares of preferred
stock of the Company having essentially the same value or economic rights as
such shares.  Immediately upon the action of the Board of Directors of the
Company authorizing any such exchange, and without any further action or any
notice, the Rights (other than Rights which are not subject to such exchange)
will terminate and the Rights will only enable holders to receive the shares
issuable upon such exchange.

                 No fractional shares of Preferred Stock will be issued upon
the exercise of any Right or Rights evidenced hereby (other than fractions
which are integral multiples of one one-thousandth of a share of Preferred
Stock, which may, at the election of the Company, be evidenced by depositary
receipts), but in lieu thereof a cash payment will be made, as provided in the
Rights Agreement.

                 No holder of this Rights Certificate shall be entitled to vote
or receive dividends or be deemed for any purpose the holder of shares of
Preferred Stock or of any

other securities of the Company which may at any time be issuable on the
exercise hereof, nor shall anything contained in the Rights Agreement or herein
be construed to confer upon the holder hereof, as such, any of the rights of a
stockholder of the Company or any right to vote for the election of directors
or upon any matter submitted to stockholders at any meeting thereof, or to give
or withhold consent to any corporate action, or, to receive notice of meetings
or other actions affecting stockholders (except as provided in the Rights
Agreement), or to receive dividends or subscription rights, or otherwise, until
the Right or Rights evidenced by this Rights Certificate shall have been
exercised as provided in the Rights Agreement.

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

Company and its corporate seal.

                                                                       Exhibit C

                         SUMMARY OF RIGHTS TO PURCHASE
                 SERIES A JUNIOR PARTICIPATING PREFERRED STOCK


                 On January 8, 1996, the Board of Directors of Helmerich &
Payne, Inc. (the "Company") approved the extension of the benefits afforded by
the Company's existing rights plan by adopting a new stockholder rights plan
and declared a dividend distribution of one Right for each outstanding share of
Common Stock of the Company to stockholders of record at the close of business
on January 8, 1996 (the expiration date of the Rights Agreement dated as of
January 21, 1986 and as amended on December 5, 1990, between the Company and
the Rights Agent named therein) (the "Record Date").  Each Right entitles the
registered holder to purchase from the Company a unit (a "Unit") consisting of
one one- thousandth of a share of Series A Junior Participating Preferred
Stock, without par value (the "Preferred Stock"), at a purchase price of $90
per Unit (the "Purchase Price"), subject to adjustment.  The description and
terms of the Rights are set forth in a Rights Agreement (the "Rights
Agreement"), dated as of January 8, 1996, between the Company and Liberty Bank
and Trust Company of Oklahoma City, N.A., as Rights Agent (the "Rights Agent").

                 Initially, the Rights will be attached to all Common Stock
certificates representing shares then outstanding, and no separate Rights
Certificates will be distributed.  The Rights will separate from the Common
Stock upon the earlier of (i) 10 business days following a public announcement
that a person or group of affiliated or associated persons (an "Acquiring
Person") has acquired, or obtained the right to acquire, beneficial ownership
of 15% or more of the outstanding shares of Common Stock (the "Stock
Acquisition Date") or (ii) 10 business days (or such later date as the Board
shall determine) following the commencement of a tender offer or exchange offer
that would result in a person or group beneficially owning 15% or more of such
outstanding shares of Common Stock (the earlier of (i) and (ii), the
"Distribution Date").  Until the Distribution Date, (i) the Rights will be
evidenced by the Common Stock certificates and will be transferred with and
only with such Common Stock certificates, (ii) new Common Stock certificates
issued after the Record Date will contain a notation incorporating the Rights
Agreement by reference and (iii) the surrender for transfer of any certificates
for Common Stock outstanding will also constitute the transfer of the Rights
associated with the





                                      C-1
<PAGE>   76
Common Stock represented by such certificate.  Pursuant to the Rights
Agreement, the Company reserves the right to require prior to the occurrence of
a Triggering Event (as defined below) that, upon any exercise of Rights, a
number of Rights be exercised so that only whole shares of Preferred Stock will
be issued.

                 The Rights are not exercisable until the Distribution Date and
will expire at the close of business on January 31, 2006 unless earlier
redeemed or exchanged by the Company as described below.  At no time will the
Rights have any voting power.

                 As soon as practicable after the Distribution Date, Rights
Certificates will be mailed to holders of record of the Common Stock as of the
close of business on the Distribution Date and, thereafter, the separate Rights
Certificates alone will represent the Rights.  Except as otherwise determined
by the Board of Directors, only shares of Common Stock issued prior to the
Distribution Date will be issued with Rights.

                 In the event that a Person becomes the beneficial owner of 15%
or more of the then outstanding shares of Common Stock (unless such acquisition
is made pursuant to a tender or exchange offer for all outstanding shares of
Common Stock, at a price determined by a majority of the independent directors
of the Company who are not representatives, nominees, Affiliates or Associates
of an Acquiring Person to be fair and otherwise in the best interest of the
Company and its stockholders after receiving advice from one or more investment
banking firms (a "Qualifying Offer")), each holder of a Right will thereafter
have the right to receive, upon exercise, Common Stock (or, in certain
circumstances, cash, property or other securities of the Company) having a
value equal to two times the exercise price of the Right.  Notwithstanding any
of the foregoing, following the occurrence of any of the events set forth in
this paragraph (the "Flip-in Events"), all Rights that are, or (under certain
circumstances specified in the Rights Agreement) were, beneficially owned by
any Acquiring Person will be null and void.  However, Rights are not
exercisable following the occurrence of any of the Flip-in Events set forth
above until such time as the Rights are no longer redeemable by the Company as
set forth below.

                 For example, at an exercise price of $90 per Right, each Right
not owned by an Acquiring Person (or by certain related parties) following a
Flip-in Event would entitle its holder to purchase $180 worth of Common Stock





                                      C-2
<PAGE>   77
(or other consideration, as noted above) for $90.  Assuming that the Common
Stock had a per share value of $30 at such time, the holder of each valid Right
would be entitled to purchase 6 shares of Common Stock for $90.

                 In the event that at any time following the Stock Acquisition
Date, (i) the Company engages in a merger or other business combination
transaction in which the Company is not the surviving corporation (other than a
merger consummated pursuant to a Qualifying Offer); (ii) the Company engages in
a merger or business combination transaction in which the Company is the
surviving corporation and the Common Stock of the Company is changed or
ex-changed; or (iii) more than 50% of the Company's assets, earning power or
cash flow is sold or transferred, each holder of a Right (except Rights which
have previously been voided as set forth above) shall thereafter have the right
to receive, upon exercise of the Right, Common Stock of the acquiring company
having a value equal to two times the exercise price of the Right.

                 At any time after the acquisition by a person or group of
affiliated or associated persons of beneficial ownership of 15% or more of the
outstanding shares of Common Stock and prior to the acquisition by such person
or group of 50% or more of the outstanding shares of Common Stock, the Board
may exchange the Rights (other than Rights owned by such person or group which
have become void), in whole or in part, at an exchange ratio of one share of
Common Stock, or one one-thousandth of a share of Preferred Stock (or of a
share of a class or series of the Company's preferred stock having equivalent
rights, preferences and privileges), per Right (subject to adjustment).

                 The Purchase Price payable, and the number of Units of
Preferred Stock or other securities or property issuable upon exercise of the
Rights are subject to adjustment from time to time to prevent dilution (i) in
the event of a stock dividend on, or a subdivision, combination or
reclassification of, the Preferred Stock, (ii) if holders of the Preferred
Stock are granted certain rights or warrants to subscribe for Preferred Stock
or convertible securities at less than the current market price of the
Preferred Stock, or (iii) upon the distribution to holders of the Preferred
Stock of evidences of indebtedness or assets (excluding regular quarterly cash
dividends) or of subscription rights or warrants (other than those referred to
above).





                                      C-3
<PAGE>   78
                 With certain exceptions, no adjustments in the Purchase Price
will be required until cumulative adjustments amount to at least 1% of the
Purchase Price.  No fractional Units will be issued and, in lieu thereof, an
adjustment in cash will be made based on the market price of the Preferred
Stock on the last trading date prior to the date of exercise.

                 At any time until 10 business days following the Stock
Acquisition Date, the Company may redeem the Rights in whole, but not in part,
at a price of $0.01 per Right (payable in cash, Common Stock or other
consideration deemed appropriate by the Board).  Immediately upon the action of
the Board of Directors ordering redemption of the Rights, the Rights will
terminate and the only right of the holders of Rights will be to receive the
$0.01 redemption price.

                 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.  While the distribution of the
Rights will not be taxable to stockholders or to the Company, stockholders may,
depending upon the circumstances, recognize taxable income in the event that
the Rights become exercisable for Common Stock (or other consideration) of the
Company or for common stock of the acquiring company as set forth above.

                 Any of the provisions of the Rights Agreement may be amended
by the Board of Directors of the Company prior to the Distribution Date.  After
the Distribution Date, the provisions of the Rights Agreement may be amended by
the Board in order to cure any ambiguity, to make changes which do not
adversely affect the interests of holders of Rights (excluding the interest of
any Acquiring Person), or to shorten or lengthen any time period under the
Rights Agreement; provided, however, that no amendment to adjust the time
period governing redemption shall be made at such time as the Rights are not
redeemable.

                 A copy of the Rights Agreement has been filed with the
Securities and Exchange Commission as an Exhibit to a Current Report on Form
8-K dated January __, 1996.  A copy of the Rights Agreement is available free
of charge from the Company.  This summary description of the Rights does not
purport to be complete and is qualified in its entirety by reference to the
Rights Agreement, which is incorporated herein by reference.
