         Item 1.   Description of Registrant's Securities to be Registered.

         On December 6, 1989, the Board of Directors of Murphy Oil Corporation
(the "Company") declared a dividend of one right (each a "Right"; collectively,
the "Rights") for each outstanding share of the Common Stock, par value $1.00
per share (the "Common Stock"), of the Company to holders of record at the close
of business on December 20, 1989 (the "Record Date"). On December 6, 1989, the
Company entered into a Rights Agreement dated as of that date (the "Original
Rights Agreement") with Harris Trust Company of New York, as Rights Agent (the
"Rights Agent"). The Original Rights Agreement and the form of the original
Rights Certificate were previously filed as Exhibits 1 and 2 to this Form 8-A on
December 13, 1989 and are incorporated herein by reference. On April 6, 1998,
the Company and the Rights Agent entered into Amendment No. 1 to the Rights
Agreement ("Amendment No. 1"). Amendment No. 1 is filed as Exhibit 3 hereto and
is incorporated herein by reference. The Original Rights Agreement as amended by
Amendment No. 1 is referred to herein as the "Rights Agreement". The terms and
conditions of the Rights are set forth in the Rights Agreement, and the
following description is qualified in its entirety by reference to the Rights
Agreement.

         Each outstanding share of Common Stock on December 20, 1989 received
one Right. Since that date one Right has been issued with each new share of
Common Stock and each share of Common Stock issued from the Company's treasury.
The Rights are attached to the outstanding shares of Common Stock and, except as
provided below, no separate Rights certificates have been or will be
distributed. As of April 6, 1998, there were 44,949,634 shares of Common Stock
outstanding. As long as the Rights are attached to the Common Stock, one Right
will be issued with each new share of Common Stock and each share of Common
Stock issued out of the Company's treasury so that all such shares will have
attached Rights. Subject to the terms hereof, each Right entitles the registered
holder to purchase from the Company a unit consisting of one one-thousandth of a
share (a "Unit") of Series A Participating Cumulative Preferred Stock, par value
$100.00 per share (the "Preferred Stock"), at a purchase price of $200.00 per
Unit (the "Purchase Price") subject to adjustment. Sixty thousand shares of
Preferred Stock have been reserved for issuance upon exercise of the Rights.

         The Rights will separate from the Common Stock and a "Distribution
Date" will occur upon the earlier of (a) the close of business on the tenth day
(or such later day as may be designated by action of a majority of the
Continuing Directors (as hereinafter defined)) after the date (the "Stock
Acquisition Date") of the first public announcement that a person or group of
affiliated or associated persons, with certain exceptions, has acquired
beneficial ownership of 15% or more of the shares of Common Stock (an "Acquiring
Person") and (b) the close of business on the tenth business day (or such later
day as may be designated by action of a majority of the Continuing Directors)
after the date of the commencement of a tender or exchange offer by any Person,
if, upon consummation hereof, such Person would be an Acquiring Person. Until
the Distribution Date (or earlier redemption, exchange or expiration of the
Rights), (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 will also constitute the transfer
of the Rights associated with the Common Stock represented by such certificate.

           The Rights are not exercisable until the Distribution Date and will
expire at the close of business on April 6, 2008, unless previously redeemed or
exchanged by the Company, as described below.

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

           If at any time following the Stock Acquisition Date, (i) the Company
is acquired in a merger or other business combination transaction, or (ii) 50%
or more of the Company's assets or earning power is sold, each holder of a Right
shall thereafter have the right to receive, upon exercise thereof at the then
current Purchase Price, common stock of the acquiring company having a value
equal to two times the Purchase Price. If a person becomes the beneficial owner
of 15% or more of the then outstanding shares of Common Stock, proper provision
will be made so that each holder of a Right, other than Rights that are, or
(under certain circumstances specified in the Rights Agreement) were,
beneficially owned by an Acquiring Person (which will thereafter be void), will
thereafter have the right to receive upon exercise that number of shares of
Common Stock having a market value of two times the Purchase Price, with certain
exceptions.

           The Purchase Price payable, and the number of shares of Preferred
Stock or other securities or property issuable, upon exercise of the Rights are
subject to adjustment from time to time to prevent dilution (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).

         With certain exceptions, no adjustment in the Purchase Price will be
required until cumulative adjustments amount to at least 1% of the Purchase
Price. No fractional 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.

           A majority of the Continuing Directors may, at their option, at any
time after any person becomes an Acquiring Person (but before any person becomes
the beneficial owner of 50% or more of the shares of Common Stock then
outstanding), exchange all or part of the Rights (other than the Rights owned by
an Acquiring Person) for shares of Common Stock at an exchange ratio of one
share of Common Stock per Right.

           The Rights may be redeemed in whole, but not in part, at a price of
$.01 per Right by the Board of Directors at any time until the tenth day after
the Stock Acquisition Date (or such later date as a majority of the Continuing
Directors then in office may designate in an amendment to the Rights Agreement).
Under certain circumstances set forth in the Rights Agreement, the decision to
redeem shall require the concurrence of a majority of the Continuing Directors.

           Immediately upon the action of the Board of Directors ordering
exchange or redemption of the Rights, with, where required, the concurrence of a
majority of the Continuing Directors, the Rights will terminate, and thereafter
the only right of the holders of Rights will be to receive shares of Common
Stock or the redemption price, as the case may be.

           "Continuing Director" means any member of the Board of Directors who
was a member of the Board prior to the time any Person becomes an Acquiring
Person or subsequently becomes a member of the Board, if such person is
recommended or approved by a majority of the Continuing Directors. Continuing
Directors do not include an Acquiring Person, or an affiliate or associate of an
Acquiring Person, or any representative of the foregoing entities.

           Until a Right is exercised, the holder will have no rights as a
stockholder of the Company (beyond those as an existing stockholder), including
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 Preferred Stock (or other consideration) of the
Company or for common stock of an acquiring company as set forth above.

           Prior to the Distribution Date, the Rights Agreement may be amended
in any respect. After the Distribution Date, the Rights Agreement may be amended
in any respect that does not adversely affect Rights holders, provided that
after a person becomes an Acquiring Person, any amendment requires the
concurrence of a majority of the Continuing Directors.

           The Rights have certain anti-takeover effects. The Rights may cause
substantial dilution to a person or group that attempts to acquire the Company
without a condition to such an offer that a substantial number of the Rights be
acquired. The Rights should not interfere with any merger or other business
combination approved by the Board of Directors (under some circumstances, with
the concurrence of the Continuing Directors) since the Rights may be redeemed by
the Company as described above.

Agreement, one one-hundredth of a share of Series A Participating Cumulative
Preferred Stock of the Company; and

         WHEREAS, the Board of Directors now desires to amend the Original

         NOW, THEREFORE, the parties hereto agree as follows:

and the Exhibits thereto (other than Exhibit C) are amended as set forth below:

          (a) references to "one-hundredth", "one-hundredths" and
         "one-hundredth[s]" shall be replaced with "one-thousandth",

         value $100.00 per share" shall be so amended.

           2. Each of the following definitions in Section 1 of the Original
Agreement is amended in its entirety to read as follows:

                  "Acquiring Person" means any Person (other than an Exempt
                  Holder) who, together with all Affiliates and Associates
                  (other than an Exempt Holder) of such Person, shall be the
                  Beneficial Owner of 15% or more of the shares of Common Stock
                  then outstanding, but shall not include the Company, any of
                  its Subsidiaries, any employee benefit plan of the Company or
                  any of its Subsidiaries or any Person organized, appointed or
                  established by the Company or any of its Subsidiaries for or
                  pursuant to the terms of any such plan. Notwithstanding the
                  foregoing, no Person shall become an "Acquiring Person" solely
                  as a result of an acquisition of shares of Common Stock by the
                  Company which, by reducing the number of shares of Common
                  Stock outstanding, increases the proportionate number of
                  shares of Common Stock beneficially owned by such Person
                  (together with all Affiliates and Associates of such Person)
                  to 15% or more of the shares of Common Stock then outstanding.

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

          (a) which such Person or any of its Affiliates or Associates (other
         than an Exempt Holder), directly or indirectly, beneficially owns (as
         determined pursuant to Rule 13d-3 under the Exchange Act as in effect
         on the date hereof);

          (b) which such Person or any of its Affiliates or Associates (other
         than an Exempt Holder), directly or indirectly, has

                       (i) the right to acquire (whether such right is
                  exercisable immediately or only upon the occurrence of certain
                  events or the passage of time or both) pursuant to any
                  agreement, arrangement or understanding (whether or not in
                  writing) or otherwise (other than pursuant to the Rights);
                  provided that a Person shall not be deemed the "Beneficial
                  Owner" of or to "beneficially own" securities tendered
                  pursuant to a tender or exchange offer made by or on behalf of
                  such Person or any of its Affiliates or Associates
                  until such tendered securities are accepted for payment or
                  exchange; or

                      (ii) the right to vote (whether such right is exercisable
                  immediately or only upon the occurrence of certain events or
                  the passage of time or both) pursuant to any agreement,
                  arrangement or understanding (whether or not in writing) or
                  otherwise; provided that a Person shall not be deemed the
                  "Beneficial Owner" of or to "beneficially own" any security
                  under this clause (ii) as a result of an agreement,
                  arrangement or understanding to vote such security if such
                  agreement, arrangement or understanding (A) arises solely from
                  a revocable proxy or consent given in response to a public
                  proxy or consent solicitation made pursuant to the applicable
                  rules and regulations under the Exchange Act and (B) is not
                  also then reportable by such Person on Schedule 13D under the
                  Exchange Act (or any comparable or successor report); or

          (c) which are beneficially owned, directly or indirectly, by any other
         Person (other than an Exempt Holder), or any Affiliate or Associate
         (other than an Exempt Holder) thereof, with which such Person or any of
         its Affiliates or Associates (other than an Exempt Holder) has any
         agreement, arrangement or understanding (whether or not in writing) for
         the purpose of acquiring, holding, voting (except pursuant to a
         revocable proxy as described in subparagraph (b)(ii) immediately above)
         or disposing of any such securities.

         "Distribution Date" means the earlier of (a) the close of business on
the tenth day (or such later day as may be designated by action of a majority of
the Continuing Directors) after the Stock Acquisition Date and (b) the close of
business on the tenth Business Day (or such later day as may be designated by
action of a majority of the Continuing Directors) after the date of the
commencement of a tender or exchange offer by any Person if, upon consummation
thereof, such Person would be an Acquiring Person.

         "Exempt Holder" means Charles H. Murphy, Jr., his spouse, his
descendants (and their spouses) and his and their Affiliates and Associates.

         "Final Expiration Date" means the close of business on April 6, 2008.

         "Purchase Price" means the price (subject to adjustment as provided
herein) at which a holder of a Right may purchase one one-thousandth of a share
of Preferred Stock (subject to adjustment as provided herein) upon exercise of a
Right, which price shall initially be $200.00.

           3. Section 6 (a) of the Original Agreement is hereby amended in its
entirety to read as follows:

          (a) At any time after the Distribution Date and prior to the
         Expiration Date, any Right Certificate or Certificates may, upon the
         terms and subject to the conditions set forth below in this Section
         6(a), be transferred or exchanged for another Right Certificate or
         Certificates evidencing a like number of Rights as the Right
         Certificate or Certificates surrendered. Any registered holder desiring
         to transfer or exchange any Right Certificate or Certificates shall
         surrender such Right Certificate or Certificates (with, in the case of
         a transfer, the form of assignment and 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. Neither the
         Rights Agent nor the Company shall be obligated to take any action
         whatsoever with respect to the transfer of any such surrendered Right
         Certificate or Certificates until the registered holder of the Rights
         has complied with the requirements of Section 7(e). Upon satisfaction
         of the foregoing requirements, the Rights Agent shall, subject to
         Sections 4(b), 7(d), 11(a)(iii), 14 and 24, countersign and deliver to
         the Person entitled thereto a Right Certificate or Certificates as so
         requested. The Company may require payment by the registered holder of
         a Right of a sum sufficient to cover any transfer tax or other
         governmental charge that may be imposed in connection with any transfer
         or exchange of any Right Certificate or Certificates.

           4. Section 7 (a) of the Original Agreement is hereby amended in its
entirety to read as follows:

          (a) The registered holder of any Right Certificate may exercise the
         Rights evidenced thereby (except as otherwise provided herein,
         including Sections 7(d) and (e), 9(c), 11(a)(iii), 23 and 24) in whole
         or in part at any time after the Distribution Date and prior to the
         Expiration Date upon surrender of the Right 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
         (in lawful money of the United States of America by certified check or
         bank draft payable to the order of the Company) of the aggregate
         Purchase Price with respect to the Rights then to be exercised and an
         amount equal to any applicable transfer tax or other governmental
         charge.

         5. Section 7 (d) of the Original Agreement is hereby amended in its
entirety to read as follows:

          (d) 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 (or any
         such Associate or Affiliate) to holders of equity interests in such
         Acquiring Person (or in any such Associate or Affiliate) or to any
         Person with whom the Acquiring Person (or any such Associate or
         Affiliate) has any continuing agreement, arrangement or understanding
         regarding the transferred Rights or (B) a transfer which the Continung
         Directors have determined is part of a plan, arrangement or
         understanding which has as a primary purpose or effect the avoidance of
         this Section 7(d) 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 this Section 7(d) and Section 4(b) are
         complied with, but shall have no liability to any holder of Right
         Certificates or other Person as a result of its failure to make any
         determinations with respect to an Acquiring Person or its Affiliates
         and Associates or any transferee of any of them hereunder.

           6. Sections 11(a) (ii) and (iii) of the Original Agreement are hereby
amended in their entirety to read as follows:

              (ii) If any Person, alone or together with its Affiliates and
         Associates, shall, at any time after the date of this Agreement, become
         an Acquiring Person, then proper provision shall promptly be made so
         that each holder of a Right shall (except as otherwise provided herein,
         including Section 7(d)) thereafter be entitled to receive, upon
         exercise thereof on or after the Distribution Date at the Purchase
         Price in effect immediately prior to the first occurrence of a Section
         11(a)(ii) Event, in lieu of Preferred Stock, such number of duly
         authorized, validly issued, fully paid and nonassessable shares of
         Common Stock of the Company (such number of shares being referred to
         herein as the "Adjustment Shares") as shall be equal to the result
         obtained by dividing

                       (x) the product obtained by multiplying the Purchase
                  Price in effect immediately prior to the first occurrence of a
                  Section 11(a)(ii) Event by the number of one one-thousandths
                  of a share of Preferred Stock for which a Right was
                  exercisable immediately prior to such first occurrence (such
                  product being thereafter referred to as the "Purchase Price"
                  for each Right and for all purposes of this Agreement) by

                       (y) 50% of the current market price (determined pursuant
                  to Section 11(d)(i)) per share of Common Stock on the date of
                  such first occurrence.

              (iii) If the number of shares of Common Stock which are authorized
         by the Company's certificate of incorporation but not outstanding or
         reserved for issuance other than upon exercise of the Rights is not
         sufficient to permit the exercise in full of the Rights in accordance
         with Section 11(a)(ii), the Company shall, with respect to each Right,
         make adequate provision to substitute for the Adjustment Shares, upon
         payment of the Purchase Price then in effect, (A) (to the extent
         available) Common Stock and then, (B) (to the extent available) other
         equity securities of the Company which a majority of the Continuing
         Directors has determined to be essentially equivalent to shares of
         Common Stock in respect to dividend, liquidation and voting rights
         (such securities being referred to herein as "common stock
         equivalents") and then, if necessary, (C) other equity or debt
         securities of the Company, cash or other assets, a reduction in the
         Purchase Price or any combination of the foregoing, having an aggregate
         value (as determined by the Continuing Directors based upon the advice
         of a nationally recognized investment banking firm selected by the
         Continuing Directors) equal to the value of the Adjustment Shares;
         provided that (x) the Company may, and (y) if the Company shall not
         have made adequate provision as required above to deliver value within
         30 days following the later of the first occurrence of a Section
         11(a)(ii) Event and the first date that the right to redeem the Rights
         pursuant to Section 23 shall expire, then the Company shall be
         obligated to, deliver, upon the surrender for exercise of a Right and
         without requiring payment of the Purchase Price, (1) (to the extent
         available) Common Stock and then (2) (to the extent available) common
         stock equivalents and then, if necessary, (3) other debt or equity
         securities to the Company, cash or other assets or any combination of
         the foregoing, having an aggregate value (as determined by the
         Continuing Directors based upon the advice of a nationally recognized
         investment banking firm selected by the Continuing Directors) equal to
         the excess of the value of the Adjustment Shares over the Purchase
         Price. If the Continuing Directors shall determine in good faith that
         it is likely that sufficient additional shares of Common Stock could be
         authorized for issuance upon exercise in full of the Rights, the 30 day
         period set forth above (such period, as it may be extended, being
         referred to herein as the "Substitution Period") may be extended to the
         extent necessary, but not more than 90 days following the first
         occurrence of a Section 11(a)(ii) Event, in order that the Company may
         seek stockholder approval for the authorization of such additional
         shares. To the extent that the Company determines that some action is
         to be taken pursuant to the first and/or second sentence of this
         Section 11(a)(iii), the Company (X) shall provide, subject to Section
         7(d), that such action shall apply uniformly to all outstanding Rights
         and (Y) may suspend the exercisability of the Rights until the
         expiration of the Substitution Period in order to seek any
         authorization of additional shares and/or to decide the appropriate
         form and value of any consideration to be delivered as referred to in
         such first and/or second sentence. If any such suspension occurs, the
         Company shall issue a public announcement stating that the
         exercisability of the Rights has been temporarily suspended, as well as
         a public announcement at such time as the suspension is no longer in
         effect. For purposes of this Section 11(a)(iii), the value of the
         Common Stock shall be the current market price per share of Common
         Stock (as determined pursuant to Section 11(d)) on the later of the
         date of the first occurrence of a Section 11(a)(ii) Event and the first
         date that the right to redeem the Rights pursuant to Section 23 shall
         expire; any "common stock equivalent" shall be deemed to have the same
         value as the Common Stock on such date; and the value of other
         securities or assets shall be determined pursuant to Section
         11(d)(iii).

           7. Section 11(d) (i) of the Original Agreement is hereby amended in
its entirety to read as follows:

              (d)(i) For the purpose of any computation hereunder other than
         computations made pursuant to Section 11(a)(iii) or 14, 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 30 consecutive Trading Days immediately prior to such
         date; for purposes of computations made pursuant to Section 11(a)(iii),
         the "current market price" per share of Common Stock on any date shall
         be deemed to be the average of the daily closing prices per share of
         such Common Stock for the 10 consecutive Trading Days immediately
         following such date; and for purposes of computations made pursuant to
         Section 14, the "current market price" per share of Common Stock for
         any Trading Day shall be deemed to be the closing price per share of
         Common Stock for such Trading Day; provided that if the current market
         price per share of the Common Stock is determined 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 exercisable for or convertible into shares
         of such Common Stock (other than the Rights), or (B) any subdivision,
         combination or reclassification of such Common Stock, and prior to the
         expiration of the requisite 30 Trading Day or 10 Trading Day period, as
         set forth above, after the ex-dividend date for such dividend or
         distribution, or the record date for such subdivision, combination or
         reclassification, then, and in each such case, the "current 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 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, 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 of the Company, or, if
         at the time of such selection there is an Acquiring Person, by a
         majority of the Continuing 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 of the Company (or, if at the time of such determination
         there is an Acquiring Person, by a majority of the Continuing
         Directors) shall be used. If the Common Stock is not publicly held or
         not so listed or traded, the "current market price" per share means the
         fair value per share as determined in good faith by the Board of
         Directors of the Company, or, if at the time of such determination
         there is an Acquiring Person, by a majority of the Continuing
         Directors, or if there are no Continuing Directors, by a nationally
         recognized investment banking firm selected by the Board of Directors,
         which determination shall be described in a statement filed with the
         Rights Agent and shall be conclusive for all purposes.

           8. Section 13 (a) (z) (1) of the Original Agreement is hereby amended
in its entirety to read as follows:

           (1) each holder of a Right shall thereafter be entitled to receive,
upon exercise thereof at the Purchase Price in effect immediately prior to the
first occurrence of any Triggering Event, such number of duly authorized,
validly issued, fully paid and nonassessable shares of freely tradeable Common
Stock of the Principal Party (as hereinafter defined), not subject to any rights
of call or first refusal, liens, encumbrances or other claims, as shall be equal
to the result obtained by dividing

              (A) the product obtained by multiplying the Purchase Price in
         effect immediately prior to the first occurrence of any Triggering
         Event by the number of one one-thousandths of a share of Preferred
         Stock for which a Right was exercisable immediately prior to such first
         occurrence (such product being thereafter referred to as the "Purchase
         Price" for each Right and for all purposes of this Agreement) by

              (B) 50% of the current market price (determined pursuant to
         Section 11(d)(i)) per share of the Common Stock of such Principal Party
         on the date of consummation of such consolidation, merger, combination,
         sale or transfer;

           9. Section 14 (a) of the Original Agreement is hereby amended in its
entirety to read as follows:

              (a) The Company shall not be required to issue fractions of
         Rights, except prior to the Distribution Date as provided in Section
         11(p), or to distribute Right Certificates which evidence fractional
         Rights. In lieu of any such fractional Rights, the Company shall pay to
         the registered holders of the Right Certificates with regard to which
         such fractional Rights would otherwise be issuable an amount in cash
         equal to the same fraction of the current market price of a whole
         Right. For purposes of this Section 14(a), the current market price of
         a whole Right shall be the closing price of a Right for the Trading Day
         immediately prior to the date on which such fractional Rights would
         otherwise have been issuable. The closing price of a Right 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, 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 or, if at the time of such selection there is an
         Acquiring Person, by a majority of the Continuing Directors. If on any
         such date no such market maker is making a market in the Rights, the
         current market price of the Rights on such date shall be as determined
         in good faith by the Board of Directors of the Company or, if at the
         time of such determination there is an Acquiring Person, by a majority
         of the Continuing Directors.

          10. Section 24(a) of the Original Agreement is hereby amended in its
entirety to read as follows:

              (a) In addition to their powers under Section 11(a)(iii), a
         majority of the Continuing Directors may, at their 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 Section 7(d)) 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 of Directors shall not be
         empowered to effect such exchange at any time after any Person (other
         than the Company, any of its Subsidiaries, any employee benefit plan of
         the Company or any of its Subsidiaries or any Person organized,
         appointed or established by the Company or any of its Subsidiaries for
         or pursuant to the terms of any such plan), together with all
         Affiliates and Associates of such Person, becomes the Beneficial Owner
         of 50% or more of the shares of Common Stock then outstanding.

         11. Section 24(b) of the Original Agreement is hereby amended in its
entirety to read as follows:

              (b) Immediately upon the action of the Continuing Directors
         electing to exchange any Rights pursuant to Section 24(a) and without
         any further action and without any notice, the right to exercise such
         Rights will terminate and thereafter the only right 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 thereafter give notice of
         such exchange to the Rights Agent and the holders of the Rights to be
         exchanged in the manner set forth in Section 26; provided that the
         failure to give, or any defect in, such notice shall not affect the
         validity of such exchange. Any notice which is mailed in the manner
         herein provided shall be deemed given, whether or not the holder
         receives the notice. Each such notice of exchange will state the method
         by which the exchange of the shares of Common Stock 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 Section 7(d)) held by each holder of Rights.

         12. Section 29 of the Original Agreement is hereby amended in its
entirety to read as follows:

         Section 29. Determinations and Actions by the Board of Directors, etc.
For all purposes of this Agreement, any calculation of the number of shares of
Common Stock outstanding at any particular time, including for purposes of
determining the particular percentage of such outstanding shares of Common Stock
of which any Person is the Beneficial Owner, shall be made in accordance with
the last sentence of Rule 13d-3(d)(1)(i) under the Exchange Act as in effect on
the date of this Agreement. The Board of Directors of the Company (or, after any
Person has become an Acquiring Person, a majority of the Continuing Directors)
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 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
exchange or not to redeem or exchange 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 (or, after any Person has become an Acquiring
Person, a majority of the Continuing Directors) 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 of Directors of
the holders of the Rights.

          13. Section 31 of the Original Agreement is hereby amended in its
entirety to read as follows:

         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 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 (or, after any Person has become an Acquiring Person, a majority of the
Continuing Directors) 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 reinstated and shall not expire until the close of business on the
tenth day following the date of such determination by the Board of Directors or
Continuing Directors, as the case may be.

          14. Exhibit A to the Original Agreement is hereby amended by :

              (a) replacing "R. Madison Murphy, Vice President, Planning" with
         "Steven A. Cosse, Senior Vice President and General Counsel" and "W.
         Bayless Rowe, Secretary" with "Walter Compton, Secretary";

              (b) replacing the second paragraph with the following paragraphs:

an amount of 350,000 shares and having the designation, voting powers,
preferences and relative, participating, optional and other special rights and
qualifications, limitations and restrictions thereof as set forth in such
resolution and (ii) the Board of Directors on April 1, 1998 adopted resolutions
authorizing and directing that the number of shares of such series of Preferred
Stock be reduced to 60,000 and approving the amendment and restatement of the
Certificate of Designation of such series of Preferred Stock;

         That no shares of such series of such series of Preferred Stock have
been issued or are outstanding; and

         That the amount, designation, voting powers, preferences and relative,
participating, optional and other special rights and qualifications, limitations
and restrictions of such series of Preferred Stock as established by the
resolutions of the Board of Directors are as follows:

          (c) in Section 1 of Exhibit A, replacing "350,000" with "60,000"; and

          (d) replacing "December, 1989" with "April, 1998" in the last page.

          15. Exhibit B to the Original Agreement is hereby amended by replacing
(w) the words "December 6, 1999" with the words "April 6, 2008", (x) the words

as of December 6, 1989".

         17. Unless otherwise specifically defined herein, each term used herein
which is defined in the Original Agreement shall have the meaning assigned to

"this Agreement" and each similar reference contained in the Original Agreement
shall from and after the date hereof refer to the Original Agreement as amended
hereby.

         18.    This Amendment No. 1 shall be governed by and construed in
accordance with the laws of the State of Delaware without giving effect to the
principles of conflict of laws thereof.

         19.    This Amendment No. 1 may be signed in any number of
counterparts, each of which shall be an original, with the same effect as if the
signatures thereto and hereto were upon the same instrument.  This Amendment
No. 1 shall become effective as of the date hereof.
