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

     On April 1, 1999, the Board of Directors of Willbros Group,
Inc. (the "Corporation") declared a distribution of one preferred
share purchase right (a "Right") for each outstanding share of
Common Stock, par value $.05 per share (the "Common Shares"), of
the Corporation.  The distribution is payable to the stockholders
of record of the Corporation on April 15, 1999 (the "Record
Date"), and with respect to Common Shares issued thereafter until
the Distribution Date (as defined below) and, in certain
circumstances, with respect to Common Shares issued after the
Distribution Date.  Except as set forth below, each Right, when
it becomes exercisable, entitles the registered holder to
purchase from the Corporation one one-thousandth of a share of
Series A Junior Participating Preferred Stock, with a par value
of $.01 per share, of the Corporation (the "Preferred Shares") at
a price of $30.00 per one one-thousandth of a Preferred Share
(the "Purchase Price"), subject to adjustment.  The description
and terms of the Rights are set forth in a Rights Agreement, as
the same may be amended from time to time (the "Rights
Agreement"), between the Corporation and ChaseMellon Shareholder
Services, L.L.C., as Rights Agent, dated as of April 1, 1999.

     Initially, the Rights will be attached to all certificates
representing Common Shares then outstanding, and no separate
Right Certificates will be distributed.  The Rights will separate
from the Common Shares upon the earlier to occur of (i) the first
date of public announcement of a person or group of affiliated or
associated persons having acquired beneficial ownership of 15
percent or more of the outstanding Common Shares (except pursuant
to a Permitted Offer, as hereinafter defined); or (ii) 10 days
(or such later date as the Board of Directors of the Corporation
(the "Board") may determine) following the commencement of, or
announcement of an intention to make, a tender offer or exchange
offer the consummation of which would result in a person or group
becoming an Acquiring Person (as hereinafter defined) (the
earlier of such dates being called the "Distribution Date").  A
person or group whose acquisition of Common Shares causes a
Distribution Date pursuant to clause (i) above is an "Acquiring
Person."  The first date of public announcement that a person or
group has become an Acquiring Person is the "Shares Acquisition
Date."

     The Rights Agreement provides that, until the Distribution
Date, the Rights will be transferred with and only with the
Common Shares.  Until the Distribution Date (or earlier
redemption or expiration of the Rights) new Common Share
certificates issued after the Record Date upon transfer or new
issuance of Common Shares will contain a notation incorporating
the Rights Agreement by reference.  Until the Distribution Date
(or earlier redemption or expiration of the Rights), the
surrender for transfer of any certificates for Common Shares
outstanding as of the Record Date, even without such notation or
a copy of this Summary of Rights being attached thereto, will
also constitute the transfer of the Rights associated with the
Common Shares represented by such certificate.  As soon as
practicable following the Distribution Date, separate
certificates evidencing the Rights ("Right Certificates") will be
mailed to holders of record of the Common Shares as of the close
of business on the Distribution Date (and to each initial record
holder of certain Common Shares issued after the Distribution
Date), and such separate Right Certificates alone will evidence
the Rights.

     The Rights are not exercisable until the Distribution Date
and will expire at the close of business on April 15, 2009,
unless earlier redeemed or exchanged by the Corporation as
described below.

                               -2-
                                
<PAGE>

     In the event that any person or group becomes an Acquiring
Person (except pursuant to a tender or exchange offer which is
for all outstanding Common Shares at a price and on terms which a
majority of certain members of the Board determines to be
adequate and in the best interests of the Corporation, its
stockholders and other relevant constituencies, other than such
Acquiring Person, its affiliates and associates (a "Permitted
Offer")), each holder of a Right will thereafter have the right
(the "Flip-In Right") to receive upon exercise the number of
Common Shares or of one onethousandths of a share of Preferred
Shares (or, in certain circumstances, other securities of the
Corporation) having a value (immediately prior to such triggering
event) equal to two times the exercise price of the Right.
Notwithstanding the foregoing, following the occurrence of the
event described above, all Rights that are, or (under certain
circumstances specified in the Rights Agreement) were,
beneficially owned by any Acquiring Person or any affiliate or
associate thereof will be null and void.

     In the event that, at any time following the Shares
Acquisition Date, (i) the Corporation is acquired in a merger or
other business combination transaction in which the holders of
all of the outstanding Common Shares immediately prior to the
consummation of the transaction are not the holders of all of the
surviving corporation's voting power, or (ii) more than 50
percent of the Corporation's assets or earning power is sold or
transferred, then each holder of a Right (except Rights which
previously have been voided as set forth above) shall thereafter
have the right (the "Flip-Over Right") to receive, upon exercise,
common shares of the acquiring company having a value equal to
two times the exercise price of the Right.  The holder of a Right
will continue to have the Flip-Over Right whether or not such
holder exercises or surrenders the Flip-In Right.

     The Purchase Price payable, and the number of Preferred
Shares, Common Shares or other securities 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
Shares, (ii) upon the grant to holders of the Preferred Shares of
certain rights or warrants to subscribe for or purchase Preferred
Shares at a price, or securities convertible into Preferred
Shares with a conversion price, less than the then current market
price of the Preferred Shares, or (iii) upon the distribution to
holders of the Preferred Shares of evidences of indebtedness or
assets (excluding regular quarterly cash dividends) or of
subscription rights or warrants (other than those referred to
above).

     The Purchase Price and number of outstanding Rights are also
subject to adjustment in the event of a stock split of the Common
Shares or a stock dividend on the Common Shares payable in Common
Shares or subdivisions, consolidations or combinations of the
Common Shares occurring, in any such case, prior to the
Distribution Date.

     Preferred Shares purchasable upon exercise of the Rights
will not be redeemable.  Each Preferred Share will be entitled to
a minimum preferential quarterly dividend payment of $10.00 per
share but, if greater, will be entitled to an aggregate dividend
per share of 1,000 times the dividend declared per Common Share.
In the event of liquidation, the holders of the Preferred Shares
will be entitled to a minimum preferential liquidation payment of
$1,000 per share; thereafter, and after the holders of the Common
Shares receive a liquidation payment of $1.00 per share, the
holders of the Preferred Shares and the holders of the Common
Shares will share the remaining assets in the ratio of 1,000 to 1
(as adjusted) for each Preferred Share and Common Share so held,
respectively.  Each Preferred Share will have 1,000 votes, voting
together with the Common Shares.  Finally, in the event of any
merger, consolidation or other transaction in which Common Shares
are exchanged,
     
                               -3-
     
<PAGE>

each Preferred Share will be entitled to receive 1,000 times the
amount received per Common Share.  These rights are protected by
customary antidilution provisions. In the event that the amount
of accrued and unpaid dividends on the Preferred Shares is
equivalent to six full quarterly dividends or more, the holders
of the Preferred Shares shall have the right, voting as a class,
to elect two directors in addition to the directors elected by
the holders of the Common Shares until all cumulative dividends
on the Preferred Shares have been paid through the last quarterly
dividend payment date or until non-cumulative dividends have been
paid regularly for at least one year.

     With certain exceptions, no adjustment in the Purchase Price
will be required until cumulative adjustments require an
adjustment of at least 1percent in such Purchase Price.  No
fractional Preferred Shares will be issued (other than fractions
which are one one-thousandth or integral multiples of one one-
thousandth of a Preferred Share, which may, at the election of
the Board, be evidenced by depositary receipts) and in lieu
thereof, an adjustment in cash will be made based on the market
price of the Preferred Shares on the last trading day prior to
the date of exercise.

     At any time prior to the earlier to occur of (i) a person
becoming an Acquiring Person or (ii) the expiration of the
Rights, and under certain other circumstances, the Corporation
may redeem the Rights in whole, but not in part, at a price of
$.005 per Right (the "Redemption Price") which redemption shall
be effective upon the action of the Board.  Additionally,
following the Shares Acquisition Date, the Corporation may redeem
the then outstanding Rights in whole, but not in part, at the
Redemption Price, provided that such redemption is in connection
with a merger or other business combination transaction or series
of transactions involving the Corporation in which all holders of
Common Shares are treated alike but not involving an Acquiring
Person or its affiliates or associates.

     At any time after any person or group becomes an Acquiring
Person and prior to the acquisition by such person or group of 50
percent or more of the outstanding Common Shares, the Board may
exchange the Rights (other than Rights owned by the Acquiring
Person, which will have become void), in whole or in part, at an
exchange ratio of one Common Share, or one one-thousandth of a
Preferred Share (or of a share of a class or series of the
Corporation's preferred stock having equivalent rights,
preferences and privileges), per Right (subject to adjustment).

     All of the provisions of the Rights Agreement may be amended
by the Board prior to the Distribution Date.  After the
Distribution Date, the provisions of the Rights Agreement may be
amended by the Board only in order to cure any ambiguity, defect
or inconsistency, to make changes which do not adversely affect
the interests of holders of Rights (excluding the interests of
any Acquiring Person), or, subject to certain limitations, to
shorten or lengthen any time period under the Rights Agreement.

     Until a Right is exercised or exchanged, the holder thereof,
as such, will have no right to vote or receive dividends or other
distributions and will have no other rights as a stockholder of
the Corporation.  While the distribution of the Rights will not
be taxable to stockholders of the Corporation, stockholders may,
depending upon the circumstances, recognize taxable income should
the Rights become exercisable or upon the occurrence of certain
events thereafter.

                        RIGHTS AGREEMENT

     THIS RIGHTS AGREEMENT (this "Agreement") is made and entered
into as of April 1, 1999, by and between Willbros Group, Inc., a
Republic of Panama corporation (the "Corporation"), and
ChaseMellon Shareholder Services, L.L.C., a New Jersey limited
liability company (the "Rights Agent").

     The Board of Directors of the Corporation has authorized and
declared a distribution of one preferred share purchase right (a
"Right") for each Common Share (as hereinafter defined) of the
Corporation outstanding at the Close of Business (as hereinafter
defined) on April 15, 1999 (the "Record Date"), each Right
representing the right to purchase one one-thousandth of a
Preferred Share (as hereinafter defined), upon the terms and
subject to the conditions herein set forth, and has further
authorized and directed the issuance of one Right with respect to
each Common Share that shall become outstanding between the
Record Date and the earliest of the Distribution Date, the
Redemption Date and the Final Expiration Date (as such terms are
hereinafter defined); provided, however, that Rights may be
issued with respect to Common Shares that shall become
outstanding after the Distribution Date and prior to the earlier
of the Redemption Date and the Final Expiration Date in
accordance with the provisions of this Agreement.

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

     Section 1.     Certain Definitions.  For purposes of this
Agreement, the following terms 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 percent or more
     of the then outstanding Common Shares (other than as a
     result of a Permitted Offer) or was such a Beneficial Owner
     at any time after the date hereof, whether or not such
     Person continues to be the Beneficial Owner of 15 percent or
     more of the then outstanding Common Shares.  Notwithstanding
     the foregoing, (i) the term "Acquiring Person" shall not
     include (A) the Corporation, (B) any Subsidiary of the
     Corporation, (C) any employee benefit plan of the
     Corporation or of any Subsidiary of the Corporation, or
     (D) any Person or entity organized, appointed or established
     by the Corporation for or pursuant to the terms of any such
     plan; and (ii) no Person shall be deemed to be an "Acquiring
     Person" either (A) as a result of the acquisition of Common
     Shares by the Corporation which, by reducing the number of
     Common Shares outstanding, increases the proportional number
     of shares beneficially owned by such Person together with

<PAGE>

     however, that, if a tender offer is terminated prior to the
     occurrence of a Distribution Date, then no Distribution Date
     shall occur as a result of such tender offer.  Upon the
     occurrence of a Distribution Date, the Corporation shall
     promptly notify the Rights Agent and request a stockholder
     list from the Corporation's transfer agent.  As soon as
     practicable after the Rights Agent receives such notice and
     list, the Corporation will prepare and execute, the Rights
     Agent will countersign, and the Corporation will send or
     cause to be sent by first-class mail, postage-prepaid, to
     each record holder of Common Shares as of the Close of
     Business on the Distribution Date, at the address of such
     holder shown on the records of the Corporation, a Right
     Certificate, substantially in the form of Exhibit B hereto
     (a "Right Certificate"), evidencing one Right for each
     Common Share so held.  As of and after the Distribution
     Date, the Rights will be evidenced solely by such Right
     Certificates.
     
          (b)  As promptly as practicable following the Record
     Date, the Corporation will send a copy of a Summary of
     Rights to Purchase Preferred Shares, in substantially the
     form of Exhibit C hereto (the "Summary of Rights"), by
     first-class mail, postage-prepaid, to each record holder of
     Common Shares as of the Close of Business on the Record
     Date, at the address of such holder shown on the records of
     the Corporation.  With respect to certificates for Common
     Shares outstanding as of the Record Date, until the
     Distribution Date, the Rights will be evidenced by such
     certificates registered in the names of the holders thereof
     together with a copy of the Summary of Rights attached
     thereto.  Until the Distribution Date (or the earlier of the
     Redemption Date or the Final Expiration Date), the surrender
     for transfer of any certificate for Common Shares
     outstanding on the Record Date, with or without a copy of
     the Summary of Rights attached thereto, shall also
     constitute the transfer of the Rights associated with such
     Common Shares.
          
          (c)  Rights shall be issued in respect of all Common
     Shares outstanding as of the Record Date or issued (on
     original issuance or out of treasury) after the Record Date
     but prior to the earliest of the Distribution Date, the
     Redemption Date and the Final Expiration Date.  In addition,
     in connection with the issuance or sale of Common Shares
     following the Distribution Date and prior to the earlier of
     the Redemption Date and the Final Expiration Date, the
     Corporation (i) shall, with respect to Common Shares so
     issued or sold, pursuant to the exercise of stock options or
     under any employee plan or arrangement or upon the exercise,
     conversion or exchange of other securities issued by the
     Corporation prior to the Distribution Date, and (ii) may, in
     any other case, if deemed necessary or appropriate by the
     Board, issue Right Certificates representing the appropriate
     number of Rights in connection with such issuance or sale;
     provided, however, that no such Right Certificate shall be
     issued if, and to the extent that (x) the Corporation shall
     be advised by counsel that such issuance would create a
     significant risk of material adverse tax consequences to the
     Corporation or the Person to whom such Right Certificate
     would be issued or (y) appropriate adjustment shall
     otherwise have been made in lieu of the issuance thereof.
          
          (d)  Certificates for Common Shares which become
     outstanding (including without limitation reacquired Common
     Shares referred to in the last sentence of this

     paragraph (d)) after the Record Date but prior to the
     earliest of the Distribution Date, the Redemption Date and
     the Final Expiration Date, shall be deemed also to be
     certificates for Rights, and shall bear the following
     legend:
     
          This certificate also evidences and entitles the
          holder hereof to certain Rights as set forth in a
          Rights Agreement between Willbros Group, Inc. and
          ChaseMellon Shareholder Services, L.L.C., dated as
          of April 1, 1999 (the "Rights Agreement"), the
          terms of which are hereby incorporated herein by
          reference and a copy of which is on file at the
          principal executive offices of Willbros Group,
          Inc.   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, may be
          redeemed or exchanged or may expire.  Willbros
          Group, Inc. will mail to the holder of this
          certificate a copy of the Rights Agreement without
          charge after receipt of a written request
          therefor.  As set forth in the Rights Agreement,
          Rights issued to, or held by, any Person who is,
          was or becomes an Acquiring Person or an Affiliate
          or Associate thereof (as such terms are defined in
          the Rights Agreement) and certain related Persons,
          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, until the Distribution Date, the Rights associated
     with the Common Shares represented by such certificates
     shall be evidenced by such certificates alone, and the
     surrender for transfer of any such certificate shall also
     constitute the transfer of the Rights associated with the
     Common Shares represented thereby.  In the event that the
     Corporation purchases or acquires any Common Shares after
     the Record Date but prior to the Distribution Date, any
     Rights associated with such Common Shares shall be deemed
     cancelled and retired so that the Corporation shall not be
     entitled to exercise any Rights associated with such Common
     Shares which are no longer outstanding.
     
     Section 4.     Form of Right Certificates.
     
          (a)  The Right Certificates (and the forms of election
     to purchase and of assignment to be printed on the reverse
     thereof) shall be substantially in the form set forth in
     Exhibit B hereto and may have such marks of identification
     or designation and such legends, summaries or endorsements
     printed thereon as the Corporation may deem appropriate
     (which do not affect the duties or responsibilities of the
     Rights Agent) and as are not inconsistent with the
     provisions of this Agreement, or as may be required to
     comply with any applicable law or with any 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 Sections 11 and 22 hereof, the
     Right Certificates shall entitle the holders thereof to
     purchase such number of one one-thousandths
          
                                7


<PAGE>
     
     of a Preferred Share as shall be set forth therein at the
     price per one one-thousandth of a Preferred Share set forth
     therein, as specified in Section 7(b) hereof (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 Right Certificate issued pursuant to
     Section 3(a) or Section 22 hereof that represents Rights
     which are null and void pursuant to Section 7(e) of this
     Agreement and any Right Certificate issued pursuant to
     Section 6 or 11 hereof upon transfer, exchange, replacement
     or adjustment of any other Right Certificate referred to in
     this sentence, shall contain (to the extent feasible) the
     following legend:
          
          The Rights represented by this Right 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 Right Certificate and the Rights
          represented hereby are null and void.
          
     Provisions of Section 7(e) of this Agreement shall be
     operative whether or not the foregoing legend is contained
     on any such Right Certificate.
     
     Section 5.     Countersignature and Registration.
     
          (a)  The Right Certificates shall be executed on behalf
     of the Corporation by its Chairman of the Board, its Chief
     Executive Officer, its President, any of its Vice
     Presidents, or its Treasurer, either manually or by
     facsimile signature, shall have affixed thereto the
     Corporation's seal or a facsimile thereof, and shall be
     attested by the Secretary or an Assistant Secretary of the
     Corporation, either manually or by facsimile signature.  The
     Right Certificates shall be countersigned by the Rights
     Agent and shall not be valid for any purpose unless so
     countersigned.  In case any officer of the Corporation who
     shall have signed any of the Right Certificates shall cease
     to be such officer of the Corporation before
     countersignature by the Rights Agent and issuance and
     delivery by the Corporation, such Right Certificates may
     nevertheless be countersigned by the Rights Agent and issued
     and delivered by the Corporation with the same force and
     effect as though the Person who signed such Right
     Certificates had not ceased to be such officer of the
     Corporation; and any Right Certificate may be signed on
     behalf of the Corporation by any Person who, at the actual
     date of the execution of such Right Certificate, shall be a
     proper officer of the Corporation to sign such Right
     Certificate, although at the date of the execution of this
     Rights Agreement any such Person was not such an officer.
          
          (b)  Following the Distribution Date and receipt by the
     Rights Agent of the notice and list of record holders of
     Rights referred to in Section 3(a) hereof, the Rights Agent
     will keep or cause to be kept, at its office designated
     pursuant to Section 26 hereof as the appropriate place for
     surrender of Right Certificates upon exercise, transfer or
     exchange,

     books for registration and transfer of the Right
     Certificates issued hereunder.  Such books shall show the
     names and addresses of the respective holders of the Right
     Certificates, the number of Rights evidenced on its face by
     each of the Right Certificates and the certificate number
     and the date of each of the Right Certificates.

     Section 6.     Transfer, Split-Up, Combination and Exchange
of Right Certificates; Mutilated, Destroyed, Lost or Stolen Right
Certificates.
     
          (a)  Subject to the provisions of Sections 4(b), 7(e)
     and 14 hereof, at any time after the Close of Business on
     the Distribution Date, and at or prior to the Close of
     Business on the earlier of the Redemption Date or the Final
     Expiration Date, any Right Certificate or Right Certificates
     may be transferred, split up, combined or exchanged for
     another Right Certificate or Right Certificates, entitling
     the registered holder to purchase a like number of one
     one-thousandth of a Preferred Share (or, following a
     Triggering Event, other securities, as the case may be) as
     the Right Certificate or Right 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 Right
     Certificate or Right Certificates shall make such request in
     writing delivered to the Rights Agent, and shall surrender
     the Right Certificate or Right Certificates to be
     transferred, split up, combined or exchanged at the office
     of the Rights Agent designated for such purpose.  Neither
     the Rights Agent nor the Corporation shall be obligated to
     take any action whatsoever with respect to the transfer of
     any such surrendered Right Certificate until the registered
     holder shall have completed and signed the certificate
     contained in the form of assignment on the reverse side of
     such Right 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 Corporation or the Rights Agent shall
     reasonably request.  Thereupon the Rights Agent shall,
     subject to Sections 4(b), 7(e) and 14 hereof, countersign
     and deliver to the Person entitled thereto a Right
     Certificate or Right Certificates, as the case may be, as so
     requested.  The Corporation may require payment of a sum
     sufficient to cover any tax or governmental charge that may
     be imposed in connection with any transfer, split up,
     combination or exchange of Right Certificates.  The Rights
     Agent may delay the processing of such transaction until it
     receives evidence that all applicable taxes and governmental
     charges have been paid.
          
          (b)  Upon receipt by the Corporation and the Rights
     Agent of evidence satisfactory to them of the loss, theft,
     destruction or mutilation of a Right Certificate, and, in
     case of loss, theft or destruction, of indemnity or security
     satisfactory to them, and, at the Corporation's request,
     reimbursement to the Corporation and the Rights Agent of all
     reasonable expenses incidental thereto, and upon surrender
     to the Rights Agent and cancellation of the Right
     Certificate if mutilated, the Corporation will make and
     deliver a new Right Certificate of like tenor to the Rights
     Agent for countersignature and delivery to the registered
     holder in lieu of, the Right Certificate so lost, stolen,
     destroyed or mutilated.

     Section 7.     Exercise of Rights; Purchase Price;
Expiration Date of Rights.
          
          (a)  Subject to Section 7(e) hereof, the registered
     holder of any Right Certificate may exercise the Rights
     evidenced thereby (except as otherwise provided herein) in
     whole or in part at any time after the Distribution Date
     upon surrender of the Right Certificate, with the form of
     election to purchase and the certificate on the reverse side
     thereof duly executed, to the Rights Agent at the office 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
     Corporation) of the aggregate Purchase Price for the total
     number of one one-thousandths of a Preferred Share (or other
     securities, as the case may be) as to which such surrendered
     Rights are exercised, and an amount equal to any applicable
     transfer tax or other governmental charge, at or prior to
     the earliest of (i) the Close of Business on April 15, 2009
     (the "Final Expiration Date"), (ii) the time at which the
     Rights are redeemed as provided in Section 23 hereof (the
     "Redemption Date"), and (iii) the time at which the Rights
     are exchanged as provided in Section 24 hereof.
          
          (b)  The Purchase Price for each one one-thousandth of
     a Preferred Share pursuant to the exercise of a Right shall
     initially be $30.00, shall be subject to adjustment from
     time to time as provided in the next sentence and in
     Sections 11 and 13(a) hereof and shall be payable in
     accordance with paragraph (c) of this Section 7.  Anything
     in this Agreement to the contrary notwithstanding, in the
     event that, at any time after the date of this Agreement and
     prior to the Distribution Date, the Corporation shall
     (i) declare or pay any dividend on the Common Shares payable
     in Common Shares or (ii) effect a subdivision, combination
     or consolidation of the Common Shares (by reclassification
     or otherwise than by payment of dividends in Common Shares)
     into a greater or lesser number of Common Shares, then, in
     any such case, each Common Share outstanding following such
     subdivision, combination or consolidation shall continue to
     have a Right associated therewith and the Purchase Price
     following any such event shall be proportionately adjusted
     to equal the result obtained by multiplying the Purchase
     Price immediately prior to such event by a fraction the
     numerator of which shall be the total number of Common
     Shares outstanding immediately prior to the occurrence of
     the event and the denominator of which shall be the total
     number of Common Shares outstanding immediately following
     the occurrence of such event.  The adjustment provided for
     in the preceding sentence shall be made successively
     whenever such a dividend is declared or paid or such a
     subdivision, combination or consolidation is effected.
          
           (c) Upon receipt of a Right Certificate representing
     exercisable Rights, with the form of election to purchase
     and the certificate duly executed, accompanied by payment of
     the Purchase Price for the Preferred Shares (or other
     securities, as the case may be) to be purchased and an
     amount equal to any applicable transfer tax or governmental
     charge required to be paid by the holder of such Right
     Certificate in accordance with Section 6 hereof by certified
     check, cashier's check or money order payable to the order
     of the Corporation, the Rights Agent shall thereupon
     promptly (i) (A) requisition from any transfer agent of the
     Preferred Shares certificates for the number of Preferred
     Shares to be purchased
     
                               10
                                
<PAGE>

     (and the Corporation hereby irrevocably authorizes its
     transfer agent to comply with all such requests), or (B) if
     the Corporation, in its sole discretion, shall have elected
     to deposit the Preferred Shares issuable upon exercise of
     the Rights hereunder into a depositary, requisition from the
     depositary agent of depositary receipts representing such
     number of one one-thousandths of a Preferred Share as are to
     be purchased (in which case certificates for the Preferred
     Shares represented by such receipts shall be deposited by
     the transfer agent with the depositary agent) and the
     Corporation will direct the depositary agent to comply with
     such requests; (ii) when appropriate, requisition from the
     Corporation the amount of cash to be paid in lieu of
     issuance 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 Right
     Certificate, registered in such name or names as may be
     designated by such holder; and (iv) when appropriate, after
     receipt thereof, deliver such cash to or upon the order of
     the registered holder of such Right Certificate.  In the
     event that the Corporation is obligated to issue other
     securities (including Common Shares) of the Corporation
     pursuant to Section 11(a) hereof, the Corporation will make
     all arrangements necessary so that such other securities are
     available for distribution by the Rights Agent, if and when
     necessary to comply with this Agreement.
          
          In addition, in the case of an exercise of the Rights
     by a holder pursuant to Section 11(a)(ii) hereof, the Rights
     Agent shall return such Right Certificate to the registered
     holder thereof after imprinting, stamping or otherwise
     indicating thereon that the rights represented by such Right
     Certificate no longer include the rights provided by
     Section 11(a)(ii) hereof and, if less than all the Rights
     represented by such Right Certificate were so exercised, the
     Rights Agent shall indicate on the Right Certificate the
     number of Rights represented thereby which continue to
     include the rights provided by Section 11(a)(ii) hereof.
          
          (d)  In case the registered holder of any Right
     Certificate shall exercise less than all the Rights
     evidenced thereby, a new Right Certificate evidencing Rights
     equivalent to the Rights remaining unexercised shall be
     issued by the Rights Agent to the registered holder of such
     Right Certificate or to his duly authorized assigns, subject
     to the provisions of Sections 6 and 14 hereof, or the Rights
     Agent shall place an appropriate notation on the Right
     Certificate with respect to those Rights exercised.
          
          (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
     Affiliate or Associate of an Acquiring Person, (ii) a transferee
     of an Acquiring Person (or of any Affiliate or Associate thereof)
     who becomes a transferee after the Acquiring Person becomes such,
     or (iii) a transferee of an Acquiring Person (or of any Affiliate
     or Associate thereof) 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 a continuing

                               11


<PAGE>

     agreement, arrangement or understanding regarding the
     transferred Rights or (B) a transfer which the Board has
     determined is part of an agreement, 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 Corporation shall notify the Rights Agent
     when this Section 7(e) applies and shall use all reasonable
     efforts to insure that the provisions of this Section 7(e)
     and Section 4(b) hereof are complied with, but neither the
     Corporation nor the Rights Agent shall have any liability to
     any holder of Right Certificates or other Person as a result
     of the Corporation's failure to make any determinations with
     respect to an Acquiring Person or its Affiliates, Associates
     or any transferee of any of them hereunder.
          
          (f)  Notwithstanding anything in this Agreement to the
     contrary, neither the Rights Agent nor the Corporation shall
     be obligated to undertake any action with respect to a
     registered holder of Rights upon the occurrence of any
     purported transfer pursuant to Section 6 hereof or exercise
     as set forth in this Section 7, unless such registered
     holder (i) shall have properly completed and signed the
     certificate contained in the form of assignment or election
     to purchase, as the case may be, set forth on the reverse
     side of the Right Certificate surrendered for such transfer
     or exercise, as the case may be, (ii) shall not have
     indicated an affirmative response to clause 1 or 2 thereof,
     and (iii) shall have provided such additional evidence of
     the identity of the Beneficial Owner (or former Beneficial
     owner) or Affiliates or Associates thereof as the
     Corporation or the Rights Agent shall reasonably request.
          
     Section 8.     Cancellation and Destruction of Right
Certificates.  All Right Certificates surrendered for the purpose
of exercise, transfer, split up, combination or exchange shall,
if surrendered to the Corporation or to any of its agents, be
delivered to the Rights Agent for  cancellation or in cancelled
form, or, if surrendered to the Rights Agent, be cancelled by it,
and no Right Certificates shall be issued in lieu thereof except
as expressly permitted by any of the provisions of this
Agreement.  The Corporation shall deliver to the Rights Agent for
cancellation and retirement, and the Rights Agent shall so cancel
and retire, any other Right Certificate purchased or acquired by
the Corporation otherwise than upon the exercise thereof.  The
Rights Agent shall deliver all cancelled Right Certificates to
the Corporation, or shall, at the written request of the
Corporation, destroy such cancelled Right Certificates, and in
such case shall deliver a certificate of destruction thereof to
the Corporation.
     
     Section 9.     Reservation and Availability of Capital
Stock.
          
          (a)  The Corporation covenants and agrees that (i) at
     all times prior to the occurrence of a Section 11(a)(ii)
     Event, it will cause to be reserved and kept available out
     of its authorized and unissued Preferred Shares, or any
     authorized and issued Preferred Shares held in its treasury,
     the number of Preferred Shares that will be sufficient to
     permit the exercise in full of all outstanding Rights, and
     (ii) after the occurrence of a Section 11(a)(ii)


                               12
                                
<PAGE>

     Event, it will, to the extent reasonably practicable, so
     reserve and keep available a sufficient number of Common
     Shares (and/or other securities) which may be required to
     permit the exercise in full of the Rights pursuant to this
     Agreement.
     
          (b)  So long as the Preferred Shares (and, after the
     occurrence of a Section 11(a)(ii) Event, Common Shares or
     any other securities) issuable upon the exercise of the
     Rights may be listed on any stock exchange, the Corporation
     shall use its best efforts to cause, from and after such
     time as the Rights become exercisable, all securities
     reserved for such issuance to be listed on such exchange
     upon official notice of issuance upon such exercise.
          
          (c)  The Corporation covenants and agrees that it will
     take all such action as may be necessary to ensure that all
     Preferred Shares (or Common Shares and/or other securities,
     as the case may be) delivered upon exercise of Rights shall,
     at the time of delivery of the certificates for such shares
     or other securities (subject to payment of the Purchase
     Price), be duly and validly authorized and issued and fully
     paid and non-assessable shares or securities.
          
          (d)  The Corporation further covenants and agrees that
     it will pay when due and payable any and all federal and
     state transfer taxes and other governmental charges which
     may be payable in respect of the issuance or delivery of the
     Right Certificates or of any Preferred Shares (or Common
     Shares and/or other securities, as the case may be) upon the
     exercise of Rights.  The Corporation shall not, however, be
     required to pay any transfer tax or other governmental
     charge which may be payable in respect of any transfer or
     delivery of Right Certificates to a Person other than, or
     the issuance or delivery of certificates or depositary
     receipts for the Preferred Shares (or Common Shares and/or
     other securities, as the case may be) in a name other than
     that of, the registered holder of the Right Certificate
     evidencing Rights surrendered for exercise, or to issue or
     to deliver any certificates or depositary receipts for
     Preferred Shares (or Common Shares and/or other securities,
     as the case may be) upon the exercise of any Rights, until
     any such tax or other governmental charge shall have been
     paid (any such tax being payable by the holder of such Right
     Certificate at the time of surrender) or until it has been
     established to the Corporation's satisfaction that no such
     tax or other governmental charge is due.
          
          (e)  The Corporation shall use its best efforts to (i) file, as
     soon as practicable following the Shares Acquisition Date (or, if
     required by law, at such earlier time following the Distribution
     Date as so required), a registration statement under 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 require
     ments of the Act and the rules and regulations thereunder) until
     the date of the expiration of the rights provided by
     Section 11(a)(ii) hereof.  The Corporation will also take such
     action as may be appropriate under the blue sky or securities
     laws of any applicable states and other jurisdictions.  The
     Corporation may temporarily suspend, for a period of time

                               13


<PAGE>

     not to exceed 90 days after the date set forth in clause (i)
     of this Section 9(e), 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 Corporation shall issue a public announcement stating
     that the exercisability of the Rights has been temporarily
     suspended, as well as a public announcement at such time as
     the suspension is no longer in effect.  Notwithstanding any
     such provision of this Agreement to the contrary, the Rights
     shall not be exercisable for securities in any jurisdiction
     if the requisite qualification in such jurisdiction shall
     not have been obtained, such exercise therefor shall not be
     permitted under applicable law, or a registration statement
     in respect of such securities shall not have been declared
     effective.
     
     Section 10.    Preferred Shares Record Date.  Each Person in
whose name any certificate for Preferred Shares (or Common Shares
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 the Preferred Shares (or Common
Shares and/or other securities, as the case may be) represented
thereby on, and such certificate shall be dated, the date upon
which the Right Certificate evidencing such Rights was duly
surrendered and payment of the Purchase Price (and any applicable
transfer taxes and other governmental charges) was made;
provided, however, that, if the date of such surrender and
payment is a date upon which the transfer books of the
Corporation relating to the Preferred Shares (or Common Shares
and/or other securities, as the case may be) are closed, such
Person shall be deemed to have become the record holder of such
shares on, and such certificate shall be dated, the next
succeeding Business Day on which the applicable transfer books
are open.
     
     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 Corporation shall at any time
          after the date of this Agreement (A) declare a dividend
          on the Preferred Shares payable in Preferred Shares,
          (B) subdivide the outstanding Preferred Shares into a
          greater number of Preferred Shares, (C) combine the
          outstanding Preferred Shares into a smaller number of
          Preferred Shares, or (D) issue any shares of its
          capital stock in a reclassification of the Preferred
          Shares (including without limitation any such
          reclassification in connection with a consolidation or
          merger in which the Corporation 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 immediately prior to the
          record date for such dividend or of the effective date
          of such subdivision, combination or reclassification,
          and the number and kind of shares of capital stock
          issuable on such date, shall be proportionately
          adjusted so that the holder of any Right exercised
          after such time shall (except as otherwise provided
          herein, including without limitation Section 7(e)
          hereof) thereafter be entitled to receive, upon
          exercise thereof at the Purchase Price in effect
          immediately prior to such date, the aggregate number
          and kind of shares of capital stock which, if such

                               14


<PAGE>

          Right had been exercised immediately prior to such date
          and at a time when the applicable transfer books of the
          Corporation were open, such holder would have been
          entitled to receive upon such exercise and by virtue of
          such dividend, subdivision, combination or
          reclassification; provided, however, that in no event
          shall the consideration to be paid upon the exercise of
          one Right be less than the aggregate par value of the
          shares of capital stock of the Corporation issuable
          upon exercise of one Right.  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) In the event 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 be made so that
          each holder of a Right shall (except as provided below
          and in Section 7(e) hereof), for a period of 60 days
          after the later of the occurrence of any such event or
          the effective date of an appropriate registration
          statement under the Act pursuant to Section 9 hereof,
          have a right to receive, upon exercise thereof at a
          price equal to the then current Purchase Price, in
          accordance with the terms of this Agreement, in lieu of
          Preferred Shares, such number of duly authorized,
          validly issued, fully paid and non-assessable Common
          Shares (or, in the discretion of the Board, one
          one-thousandths of a Preferred Share) as shall equal
          the result obtained by (A) multiplying the then current
          Purchase Price by the then number of one
          one-thousandths of a Preferred Share for which a Right
          was exercisable immediately prior to the first
          occurrence of a Section 11(a)(ii) Event, and dividing
          that product by (B) 50 percent of the then current per
          share market price of the Common Shares (determined
          pursuant to Section 11(d) hereof) on the date of such
          first occurrence (such number of shares being referred
          to as the "Adjustment Shares"); provided, however,
          that, if the transaction that would otherwise give rise
          to the foregoing adjustment is also subject to the
          provisions of Section 13 hereof, then only the
          provisions of Section 13 hereof shall apply and no
          adjustment shall be made pursuant to this
          Section 11(a)(ii).
               
               (iii)     In the event that there shall not be
          sufficient treasury shares or authorized but unissued
          (and unreserved) Common Shares to permit the exercise
          in full of the Rights in accordance with
          Section 11(a)(ii) hereof and the Rights become so
          exercisable (and the Board has determined to make the
          Rights exercisable into fractions of a Preferred
          Share), notwithstanding any other provision of this
          Agreement, to the extent necessary and permitted by
          applicable law, each Right shall thereafter represent
          the right to receive, upon exercise thereof at the then
          current Purchase Price in accordance with the terms of
          this Agreement, (A) a number of (or fractions of)
          Common Shares (up to the maximum number of Common
          Shares which may permissibly be issued) and (B) one
          one-thousandths of a Preferred Share or a number of, or
          fractions of other equity securities of the Corporation
          (or, in the

                               15


<PAGE>

          discretion of the Board, debt) which the Board has
          determined to have the same aggregate current market
          value (determined pursuant to Sections 11(d)(i)
          and (ii) hereof, to the extent applicable) as one
          Common Share (such number of, or fractions of,
          Preferred Shares or other equity securities or debt of
          the Corporation being referred to as a "capital stock
          equivalent"), equal in the aggregate to the number of
          Adjustment Shares; provided, however, if sufficient
          Common Shares and/or capital stock equivalents are
          unavailable, then the Corporation shall, to the extent
          permitted by applicable law, take all such action as
          may be necessary to authorize additional Common Shares
          or capital stock equivalents for issuance upon exercise
          of the Rights, including the calling of a meeting of
          stockholders; and provided further, that, if the
          Corporation is unable to cause sufficient Common Shares
          and/or capital stock equivalents to be available for
          issuance upon exercise in full of the Rights, then each
          Right shall thereafter represent the right to receive
          the Adjusted Number of Shares upon exercise at the
          Adjusted Purchase Price (as such terms are hereinafter
          defined).  As used herein, the term "Adjusted Number of
          Shares" shall mean that number of (or fractions of)
          Common Shares (and/or capital stock equivalents) equal
          to the product of (X) the number of Adjustment Shares
          and (Y) a fraction, the numerator of which is the
          number of Common Shares (and/or capital stock
          equivalents) available for issuance upon exercise of
          the Rights and the denominator of which is the
          aggregate number of Adjustment Shares otherwise
          issuable upon exercise in full of all Rights (assuming
          there were a sufficient number of Common Shares
          available) (such fraction being referred to as the
          "Proration Factor").  The "Adjusted Purchase Price"
          shall mean the product of the Purchase Price and the
          Proration Factor.  The Board may, but shall not be
          required to, establish procedures to allocate the right
          to receive Common Shares and capital stock equivalents
          upon exercise of the Rights among holders of Rights.
          
          (b)  In case the Corporation shall fix a record date
     for the issuance of rights (other than the Rights), options
     or warrants to all holders of Preferred Shares entitling
     them (for a period expiring within 45 calendar days after
     such record date) to subscribe for or purchase Preferred
     Shares (or shares having the same rights, privileges and
     preferences as the Preferred Shares ("equivalent preferred
     shares")) or securities convertible into or exercisable for
     Preferred Shares or equivalent preferred shares at a price
     per Preferred Share or equivalent preferred share (or having
     a conversion price per share, if a security convertible into
     Preferred Shares or equivalent preferred shares) less than
     the then current per share market price of the Preferred
     Shares (as determined pursuant to Section 11(d) hereof) on
     such record date, the Purchase Price to be in effect after
     such record date shall be determined by multiplying the
     Purchase Price in effect immediately prior to such record
     date by a fraction, the numerator of which shall be the
     number of Preferred Shares outstanding on such record date
     plus the number of Preferred Shares which the aggregate
     offering price of the total number of Preferred Shares
     and/or equivalent preferred shares so to be offered (and/or
     the aggregate initial conversion price of the convertible
     securities so to be offered) would purchase at such current
     per share market price, and the denominator of which shall
     be the

                               16


<PAGE>

     number of Preferred Shares outstanding on such record date
     plus the number of additional Preferred Shares and/or
     equivalent preferred shares to be offered for subscription
     or purchase (or into which the convertible securities so to
     be offered are initially convertible); provided, however,
     that in no event shall the consideration to be paid upon the
     exercise of one Right be less than the aggregate par value
     of the shares of capital stock of the Corporation issuable
     upon exercise of one Right.  In case such subscription price
     may be paid by delivery of consideration part or all of
     which shall be in a form other than cash, the value of such
     consideration shall be as determined in good faith by the
     Board, whose determination shall be described in a statement
     filed with the Rights Agent and shall be conclusive for all
     purposes.  Preferred Shares owned by or held for the account
     of the Corporation shall not be deemed outstanding for the
     purpose of any such computation.  Such adjustment shall be
     made successively whenever such a record date is fixed; and
     in the event that such rights, options or warrants are not
     so issued, the Purchase Price shall be adjusted to be the
     Purchase Price which would then be in effect if such record
     date had not been fixed.
          
          (c)  In case the Corporation shall fix a record date
     for the making of a distribution to all holders of the
     Preferred Shares (including any such distribution made in
     connection with a consolidation or merger in which the
     Corporation is the continuing or surviving corporation) of
     evidences of indebtedness, equity securities other than
     Preferred Shares or assets (other than a regular periodic
     cash dividend or a dividend payable in Preferred Shares) or
     subscription rights, options or warrants (excluding those
     referred to in Section 11(b) hereof), the Purchase Price to
     be in effect after such record date shall be determined by
     multiplying the Purchase Price in effect immediately prior
     to such record date by a fraction, the numerator of which
     shall be the then current per share market price (as
     determined pursuant to Section 11(d) hereof) of the
     Preferred Shares on such record date, less the fair market
     value (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)
     of the portion of the assets, equity securities or evidences
     of indebtedness so to be distributed or of such subscription
     rights, options or warrants applicable to one Preferred
     Share, and the denominator of which shall be such current
     per share market price of the Preferred Shares; provided,
     however, that in no event shall the consideration to be paid
     upon the exercise of one Right be less than the aggregate
     par value of the shares of capital stock of the Corporation
     to be issued upon exercise of one Right.  Such adjustments
     shall be made successively whenever such a record date is
     fixed; and, in the event that such distribution is not so
     made, the Purchase Price shall again be adjusted to be the
     Purchase Price which would then be in effect if such record
     date had not been fixed.
          
          (d)  (i) For the purpose of any computation hereunder, the
          "current per share market price" of any security (a "Security"
          for the purpose of this Section 11(d)(i)) on any date shall be
          deemed to be the average of the daily closing prices per share of
          such Security for the 30 consecutive Trading Days immediately
          prior to and not including such date; provided, however, that, in
          the event the current per share market price of the Security is
          determined during a period following the

                               17


<PAGE>

          announcement by the issuer of such Security of (A) a
          dividend or distribution on such Security payable in
          shares of such Security or securities convertible into
          such shares or (B) any subdivision, combination or
          reclassification of such Security and prior to the
          expiration of 30 Trading Days after the ex-dividend
          date for such dividend or distribution or the record
          date for such subdivision, combination or reclassifi
          cation, then, and in each such case, the current per
          share market price shall be appropriately adjusted to
          reflect the current market price per share equivalent
          of such Security.  The closing price for each day shall
          be the last sale price, regular way, or, in case no
          such sale takes place on such day, the average of the
          closing bid and asked prices, regular way, in either
          case as reported in the principal consolidated
          transaction reporting system with respect to securities
          listed or admitted to trading on the New York Stock
          Exchange or, if the Security is not listed or admitted
          to trading on the New York Stock Exchange, as reported
          in the principal consolidated transaction reporting
          system with respect to securities listed on the
          principal national securities exchange on which the
          Security is listed or admitted to trading or, if the
          Security is not listed or admitted to trading on any
          national securities exchange, the last quoted price or,
          if not so quoted, the average of the high bid and low
          asked prices in the over-the-counter market, as
          reported by The Nasdaq Stock Market ("NASDAQ") or such
          other system then in use, or, if on any such date the
          Security is not quoted by any such organization, the
          average of the closing bid and asked prices as
          furnished by a professional market maker making a
          market in the Security selected by the Board.  If on
          any such date no such market maker is making a market
          in the Security, the fair value of the Security on such
          date as determined in good faith by the Board shall be
          used.  The term "Trading Day" shall mean a day on which
          the principal national securities exchange on which the
          Security is listed or admitted to trading is open for
          the transaction of business or, if the Security is not
          listed or admitted to trading on any national
          securities exchange, a Business Day.
          
               (ii) For the purpose of any computation hereunder,
          the "current per share market price" of the Preferred
          Shares shall be determined in accordance with the
          method set forth in Section 11(d)(i) hereof.  If the
          Preferred Shares are not publicly traded, the "current
          per share market price" of the Preferred Shares shall
          be conclusively deemed to be the current per share
          market price of the Common Shares as determined
          pursuant to Section 11(d)(i) hereof (appropriately
          adjusted to reflect any stock split, stock dividend or
          similar transaction occurring after the date of this
          Agreement), multiplied by 1,000.  If neither the Common
          Shares nor the Preferred Shares are publicly held or so
          listed or traded, "current per share market price" of
          the Preferred Shares 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.
               
          (e)  Anything herein to the contrary notwithstanding,
     no adjustment in the Purchase Price shall be required unless
     such adjustment would require an increase or

                               18


<PAGE>

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

          (f)  If, as a result of an adjustment made pursuant to
     Section 11(a)(ii) or 13(a) hereof, the holder of any Right
     thereafter exercised shall become entitled to receive, upon
     exercise of such Right, any shares of capital stock of the
     Corporation other than Preferred Shares, thereafter the
     number of other shares so receivable upon exercise of any
     Right shall be subject to adjustment from time to time in a
     manner and on terms as nearly equivalent as practicable to
     the provisions with respect to the Preferred Shares
     contained in Sections 11(a) through (c) hereof, inclusive,
     and the provisions of Sections 7, 9, 10, 13 and 14 hereof
     with respect to the Preferred Shares shall apply on like
     terms to any such other shares.
          
          (g)  All Rights originally issued by the Corporation
     subsequent to any adjustment made hereunder shall evidence
     the right to purchase, at the adjusted Purchase Price, the
     number of one one-thousandths of a Preferred Share and other
     capital stock of the Corporation purchasable from time to
     time hereunder upon exercise of the Rights, all subject to
     further adjustment as provided herein.
          
          (h)  The Corporation 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-thousandths of a Preferred Share purchasable upon the
     exercise of a Right.  Each of the Rights outstanding after
     such adjustment of the number of Rights shall be exercisable
     for the number of one one-thousandths of a Preferred Share
     for which a Right was exercisable immediately prior to such
     adjustment.  Each Right held of record prior to such
     adjustment of the number of Rights shall become that number
     of Rights (calculated to the nearest one ten-thousandth)
     obtained by dividing the Purchase Price in effect
     immediately prior to adjustment of the Purchase Price by the
     Purchase Price in effect immediately after adjustment of the
     Purchase Price.  The Corporation shall make a public
     announcement (and shall promptly deliver a copy of such
     announcement to the Rights Agent) of its election to adjust
     the number of Rights, indicating the record date for the
     adjustment and, if known at the time, the amount of the
     adjustment to be made.  This record date may be the date on
     which the Purchase Price is adjusted or any day thereafter,
     but, if the Right Certificates have been issued, shall be at
     least 10 days later than the date of the public
     announcement.  If Right Certificates have been issued, upon
     each adjustment of the number of Rights pursuant to this
     Section 11(h), the Corporation shall, as promptly as
     practicable, cause to be distributed to holders of record of
     Right Certificates on such record date Right Certificates
     evidencing, subject to Section 14 hereof, the additional
     Rights to which such holders shall be entitled as

                               19


<PAGE>

     a result of such adjustment or, at the option of the
     Corporation, shall cause to be distributed to such holders
     of record in substitution and replacement for the Right
     Certificates held by such holders prior to the date of
     adjustment, and upon surrender thereof, if required by the
     Corporation, new Right Certificates evidencing all the
     Rights to which such holders shall be entitled after such
     adjustment.  Right Certificates so to be distributed shall
     be issued, executed and countersigned in the manner provided
     for herein (and may, at the option of the Corporation,
     reflect the adjusted Purchase Price) and shall be registered
     in the names of the holders of record of Right Certificates
     on the record date specified in the public announcement.
     
          (i)  Irrespective of any adjustment or change in the
     Purchase Price or the number of one one-thousandths of a
     Preferred Share issuable upon the exercise of the Rights,
     the Right Certificates theretofore and thereafter issued may
     continue to express the Purchase Price and the number of one
     one-thousandths of a Preferred Share which were expressed in
     the initial Right Certificates issued hereunder.
          
          (j)  Before taking any action that would cause an
     adjustment reducing the Purchase Price below the then par
     value, if any, of the number of one one-thousandths of a
     Preferred Share, Common Shares or other securities issuable
     upon exercise of the Rights, the Corporation shall take any
     corporate action which may, in the opinion of its counsel,
     be necessary in order that the Corporation may validly and
     legally issue such number of fully paid and non-assessable
     one one-thousandths of a Preferred Share, Common Shares or
     other securities at such adjusted Purchase Price.
          
          (k)  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 Corporation
     may elect (and shall provide the Rights Agent with notice of
     such election) to defer, until the occurrence of such event,
     the issuance to the holder of any Right exercised after such
     record date of the Preferred Shares, Common Shares or other
     securities of the Corporation, if any, issuable upon such
     exercise over and above the Preferred Shares, Common Shares
     or other securities of the Corporation, if any, issuable
     upon exercise on the basis of the Purchase Price in effect
     prior to such adjustment; provided, however, that the
     Corporation shall deliver to such holder a due bill or other
     appropriate instrument evidencing such holder's right to
     receive such additional shares upon the occurrence of the
     event requiring such adjustment.
          
          (l)  Anything in this Section 11 to the contrary
     notwithstanding, the Corporation shall be entitled to make
     such reductions in the Purchase Price, in addition to those
     adjustments expressly required by this Section 11, as and to
     the extent that it, in its sole discretion, shall determine
     to be advisable in order that any (i) consolidation or
     subdivision of the Preferred Shares, (ii) issuance wholly
     for cash of Preferred Shares at less than the current market
     price, (iii) issuance wholly for cash of Preferred Shares or
     securities which by their terms are convertible into or
     exchangeable for Preferred Shares, (iv) stock dividends, or
     (v) issuance of rights, options or warrants referred to in
     this Section 11, hereafter made

                               20


<PAGE>

     by the Corporation to holders of its Preferred Shares shall
     not be taxable to such stockholders.
          
          (m)  The Corporation covenants and agrees that it will
     not, at any time after the Distribution Date,
     (i) consolidate, merge or otherwise combine with any other
     Person (other than a Subsidiary of the Corporation in a
     transaction which does not violate Section 11(n) hereof), or
     (ii) sell or otherwise transfer (or permit any Subsidiary of
     the Corporation to sell or otherwise transfer), in one
     transaction or a series of related transactions, assets or
     earning power aggregating more than 50percent of the assets
     or earning power of the Corporation and its Subsidiaries
     (taken as a whole) to any other Person or Persons (other
     than the Corporation and/or any of its Subsidiaries in one
     or more transactions each of which does not violate
     Section 11(n) hereof), if (x) at the time of or immediately
     after such consolidation, merger, combination, sale or
     transfer there are any charter or by-law provisions or any
     rights, warrants or other instruments or securities
     outstanding or agreements in effect or other actions taken,
     which would materially 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, combination, sale or transfer, 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.  The Corporation shall not
     consummate any such consolidation, merger, combination, sale
     or transfer unless prior thereto the Corporation and such
     other Person shall have executed and delivered to the Rights
     Agent a supplemental agreement evidencing compliance with
     this Section 11(m).
          
          (n)  The Corporation covenants and agrees that, after
     the Distribution Date, it will not, except as permitted by
     Section 23, 24 or 27 hereof, take (or permit any of its
     Subsidiaries to take) any action the purpose of which is to,
     or if at the time such action is taken it is reasonably
     foreseeable that the effect of such action would be to,
     materially diminish or otherwise eliminate the benefits
     intended to be afforded by the Rights.
          
          (o)  The exercise of Rights under Section 11(a)(ii)
     hereof shall only result in the loss of rights under said
     Section 11(a)(ii) to the extent so exercised and shall not
     otherwise affect the rights represented by the Rights under
     this Agreement, including the rights represented by
     Section 13 hereof.
          
          (p)  Unless the Corporation shall have exercised its
     election as provided in Section 11(h) hereof, upon each
     adjustment of the Purchase Price as a result of the
     calculations made in Section 11(b) or (c) hereof, each Right
     outstanding immediately prior to the making of such
     adjustment shall thereafter evidence the right to purchase,
     at the adjusted Purchase Price, that number of one
     one-thousandths of a Preferred Share (calculated to the
     nearest one-millionth) obtained by (i) multiplying (A) the
     number of one one-thousandths of a share for which a Right
     was exercisable immediately prior to this adjustment by
     (B) the Purchase Price in effect immediately prior to such
     adjustment of the

                               21


<PAGE>

     Purchase Price, and (ii) dividing the product so obtained by
     the Purchase Price in effect immediately after such
     adjustment of the Purchase Price.

     Section 12.    Certificate of Adjusted Purchase Price or
Number of Shares.  Whenever an adjustment is made as provided in
Section 11 or 13 hereof, the Corporation shall promptly
(a) prepare a certificate setting forth such adjustment, and a
brief, reasonably detailed statement of the facts, computations
and methodology giving rise to such adjustment, (b) file with the
Rights Agent and with each transfer agent for the Common Shares
and the Preferred Shares a copy of such certificate, and (c) mail
a brief summary thereof to each holder of a Right Certificate
(or, if prior to the Distribution Date, to each holder of a
certificate representing Common Shares) 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 and shall have no duty with respect to and shall not be
deemed to have knowledge of such adjustment unless and until it
shall have received such certificate.

     Section 13.    Consolidation, Merger or Sale or Transfer of
Assets or Earning Power.
          
          (a)  In the event that, on or following the Shares
     Acquisition Date, directly or indirectly, (x) the
     Corporation shall consolidate with, merge with and into, or
     otherwise combine with any Person (and the Corporation shall
     not be the continuing or surviving corporation of such
     consolidation, merger or combination), (y) the Corporation
     shall merge or otherwise combine with any Person, and the
     Corporation shall be the continuing or surviving corporation
     of such merger or combination (other than, in a case of any
     transaction described in clause (x) or (y) above, a merger,
     consolidation or combination which would result in all of
     the securities generally entitled to vote in the election of
     directors ("voting securities") of the Corporation
     outstanding immediately prior thereto continuing to
     represent (either by remaining outstanding or by being
     converted into securities of the surviving entity) all of
     the voting securities of the Corporation or such surviving
     entity outstanding immediately after such merger,
     consolidation or combination and the holders of such
     securities not having changed as a result of such merger,
     consolidation or combination), or (z) the Corporation 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 or
     earning power aggregating more than 50 percent of the assets
     or earning power of the Corporation and its Subsidiaries
     (taken as a whole) to any Person (other than the Corporation
     or any Subsidiary of the Corporation in one or more
     transactions each of which does not violate Section 11(n)
     hereof), then, and in each such case (except as provided in
     Section 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 a price equal to the
     then current Purchase Price, in accordance with the terms of
     this Agreement and in lieu of Preferred Shares, such number
     of duly authorized, validly issued, fully paid,
     non-assessable and freely tradeable Common Shares of the
     Principal Party (as hereinafter defined), not subject to any
     liens, encumbrances, rights of call or first refusal or
     other adverse claims, as shall equal the result obtained by
     (A) multiplying the then current Purchase Price by the
     number of one one-thousandths of a Preferred Share for which
     a Right

                               22


<PAGE>

     is then exercisable (without taking into account any
     adjustment previously made pursuant to Section 11(a)(ii)
     hereof) and dividing that product by (B) 50 percent of the
     then current per share market price of the Common Shares of
     such Principal Party (determined pursuant to
     Section 11(d)(i) hereof) 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
     Corporation pursuant to this Agreement; (iii) the term
     "Corporation" 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; and (iv) such Principal Party shall take
     such steps (including without limitation the authorization
     and reservation of a sufficient number of its Common Shares
     to permit exercise of all outstanding Rights in accordance
     with this Section 13(a)) 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 the Common
     Shares of such Principal Party thereafter deliverable upon
     the exercise of the Rights.
     
          (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) hereof, the Person that is the issuer of
          any securities into which Common Shares of the
          Corporation are converted in such merger, consolidation
          or combination, and if no securities are so issued, the
          Person that survives or results from such merger,
          consolidation or combination; and
               
               (ii) in the case of any transaction described in
          clause (z) of the first sentence of Section 13(a)
          hereof, 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 of the foregoing cases,
          (A) if the Common Shares of such Person are not at such
          time and have not been continuously over the preceding
          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 Shares of which
          are and have been so registered, "Principal Party"
          shall refer to such other Person; (B) in case such
          Person is a Subsidiary, directly or indirectly, of more
          than one Person, the Common Shares 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 Shares having the greatest
          aggregate market value; and (C) in case such Person is
          owned, directly or indirectly, by a joint venture
          formed by two or more Persons that are not owned,
          directly or indirectly, by the same Person, the rules
          set forth in clauses (A) and (B) above shall apply to
          each of the chains of ownership having an interest in
          such joint venture as if such party were a "Subsidiary"
          of both or all of such joint venturers and the
          Principal Parties in each such chain shall bear the
          obligations set

                               23


<PAGE>

          forth in this Section 13 in the same ratio as their direct
          or indirect interests in such Person bear to the total of
          such interests.
     
          (c)  The Corporation shall not consummate any such
     consolidation, merger, combination, sale or transfer unless
     the Principal Party shall have a sufficient number of its
     authorized Common Shares 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 Corporation and such Principal Party shall have
     executed and delivered to the Rights Agent a supplemental
     agreement providing for the terms set forth in
     Sections 13(a) and (b) hereof and further providing that, as
     soon as practicable after the date of any consolidation,
     merger, combination, sale or transfer mentioned in
     Section 13(a) hereof, the Principal Party, at its own
     expense, shall:
          
               (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 Final
          Expiration Date;
               
               (ii) use its best efforts to qualify or register
          the Rights and the securities purchasable upon exercise
          of the Rights under the blue sky or securities laws of
          such jurisdictions as may be necessary or appropriate;
          and
               
               (iii)     deliver to holders of the Rights
          historical financial statements for the Principal Party
          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, consolidations, combinations, sales and
     other transfers.  The rights under this Section 13 shall be
     in addition to the rights to exercise Rights and adjustments
     under Section 11(a)(ii) hereof and shall survive any
     exercise thereof.
     
          (d)  Notwithstanding anything in this Agreement to the
     contrary, this Section 13 shall not be applicable to a
     transaction described in clauses (x) and (y) of
     Section 13(a) hereof if: (i) such transaction is consummated
     with a Person or Persons who acquired Common Shares pursuant
     to a Permitted Offer (or a wholly owned Subsidiary of any
     such Person or Persons); (ii) the price per Common Share
     offered in such transaction is not less than the price per
     Common Share paid to all holders of Common Shares whose
     shares were purchased pursuant to such Permitted Offer; and
     (iii) the form of consideration offered in such transaction
     is the same as the form of consideration paid pursuant to
     such Permitted Offer.  Upon consummation of any such
     transaction contemplated by this Section 13(d), all Rights
     hereunder shall expire.

     Section 14.    Fractional Rights and Fractional Shares.
          
          (a)  The Corporation shall not be required to issue
     fractions of Rights or to distribute Right Certificates
     which evidence fractional Rights.  In lieu of such
     fractional Rights, there shall be paid to the registered
     holders of the Right Certificates, with regard to which such
     fractional Rights would otherwise be issuable, an amount in
     cash equal to the same fraction of the current market value
     of a whole Right.  For the purposes of this Section 14(a),
     the current market value of a whole Right shall be the
     closing price of the Rights for the Trading Day immediately
     prior to the date on which such fractional Rights would have
     been otherwise issuable.  The closing price for any day
     shall be the last sale price, regular way, or, in case no
     such sale takes place on such day, the average of the
     closing bid and asked prices, regular way, in either case as
     reported in the principal consolidated transaction reporting
     system with respect to securities listed or admitted to
     trading on the New York Stock Exchange or, if the Rights are
     not listed or admitted to trading on the New York Stock
     Exchange, as reported in the principal consolidated
     transaction reporting system with respect to securities
     listed on the principal national securities exchange on
     which the Rights are listed or admitted to trading or, if
     the Rights are not listed or admitted to trading on any
     national securities exchange, the last quoted price or, if
     not so quoted, the average of the high bid and low asked
     prices in the over-the-counter market, as reported by NASDAQ
     or such other system then in use or, if on any 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.  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 shall be used.
          
          (b)  The Corporation shall not be required to issue
     fractions of Preferred Shares (other than fractions which
     are one one-thousandth or integral multiples of one
     one-thousandth of a Preferred Share) upon exercise of the
     Rights or to distribute certificates which evidence
     fractional Preferred Shares (other than fractions which are
     one one-thousandth or integral multiples of one
     one-thousandth of a Preferred Share).  Fractions of
     Preferred Shares in integral multiples of one one-thousandth
     of a Preferred Share may, at the election of the
     Corporation, be evidenced by depositary receipts, pursuant
     to an appropriate agreement between the Corporation and a
     depositary selected by it; provided, that such agreement
     shall provide that the holders of such depositary receipts
     shall have the rights, privileges and preferences to which
     they are entitled as beneficial owners of the Preferred
     Shares represented by such depositary receipts.  In lieu of
     fractional Preferred Shares that are not one one-thousandth
     or integral multiples of one one-thousandth of a Preferred
     Share, the Corporation shall pay to the registered holders
     of Right Certificates at the time such Rights are exercised
     as herein provided an amount in cash equal to the same
     fraction of the current market value of one one-thousandth
     of a Preferred Share.  For the purposes of this
     Section 14(b), the current market value of one
     one-thousandth of a Preferred Share shall be one
     one-thousandth of the closing price of a Preferred Share (as
     determined

                               25


<PAGE>

     pursuant to Section 11(d)(ii) hereof) for the Trading Day
     immediately prior to the date of such exercise.

          (c)  Following the occurrence of one of the
     transactions or events specified in Section 11 hereof giving
     rise to the right to receive Common Shares, capital stock
     equivalents (other than Preferred Shares) or other
     securities upon the exercise of a Right, the Corporation
     shall not be required to issue fractions of shares or units
     of such Common Shares, capital stock equivalents or other
     securities upon exercise of the Rights or to distribute
     certificates which evidence fractions of such Common Shares,
     capital stock equivalents or other securities.  In lieu of
     fractional shares or units of such Common Shares, capital
     stock equivalents or other securities, the Corporation may
     pay to the registered holders of Right Certificates at the
     time such Rights are exercised as herein provided an amount
     in cash equal to the same fraction of the current market
     value of a share or unit of such Common Shares, capital
     stock equivalents or other securities.  For purposes of this
     Section 14(c), the current market value shall be determined
     in the manner set forth in Section 11(d) hereof for the
     Trading Day immediately prior to the date of such exercise
     and, if such capital stock equivalent is not traded, each
     such capital stock equivalent shall have the value of one
     one-thousandth of a Preferred Share.
          
          (d)  The holder of a Right, by the acceptance of the
     Right, expressly waives his right to receive any fractional
     Rights or any fractional share 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 (except the rights of action given to
the Rights Agent under Section 18 hereof) are vested in the
respective registered holders of the Right Certificates (and,
prior to the Distribution Date, the registered holders of the
Common Shares); and any registered holder of any Right
Certificate (or, prior to the Distribution Date, of the Common
Shares), without the consent of the Rights Agent or of the holder
of any other Right Certificate (or, prior to the Distribution
Date, of the Common Shares), may, in his own behalf and for his
own benefit, enforce, and may institute and maintain any suit,
action or proceeding against the Corporation to enforce, or
otherwise act in respect of, his right to exercise the Rights
evidenced by such Right Certificate (or, prior to the
Distribution Date, such Common Shares) in the manner provided in
such Right Certificate and in this Agreement.  Without limiting
the foregoing or any remedies available to the holders of Rights,
it is specifically acknowledged that the holders of Rights would
not have an adequate remedy at law for any breach of this
Agreement and will be entitled to specific performance of the
obligations under, and injunctive relief against actual or
threatened violations of the obligations of any Person subject
to, this Agreement.
     
     Section 16.    Agreement of Right Holders.  Every holder of
a Right, by accepting the same, consents and agrees with the
Corporation and the Rights Agent and with every other holder of a
Right as follows:

                               26


<PAGE>

          (a)  Prior to the Distribution Date, the Rights will be
     transferable only in connection with the transfer of the
     Common Shares.
          
          (b)  After the Distribution Date, the Right
     Certificates are transferable only on the registry books of
     the Rights Agent if surrendered at the office of the Rights
     Agent designated for such purpose, duly endorsed or
     accompanied by a proper instrument of transfer and with the
     appropriate form fully executed.
          
          (c)  Subject to Sections 6 and 7(f) hereof, the
     Corporation and the Rights Agent may deem and treat the
     Person in whose name the Right Certificate (or, prior to the
     Distribution Date, the associated Common Shares certificate)
     is registered as the absolute owner thereof and of the
     Rights evidenced thereby (notwithstanding any notations of
     ownership or writing on the Right Certificate or the
     associated Common Shares certificate made by anyone other
     than the Corporation or the Rights Agent) for all purposes
     whatsoever, and neither the Corporation nor the Rights
     Agent, subject to the last sentence of Section 7(e) hereof,
     shall be affected by any notice to the contrary.
          
          (d)  Notwithstanding anything in this Agreement to the
     contrary, neither the Corporation nor the Rights Agent shall
     have any liability to any holder of a Right or a beneficial
     interest in 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, judgment or ruling
     (whether interlocutory or final) 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
     Corporation must use its best efforts to have any such
     order, decree, judgment or ruling lifted or otherwise
     overturned as soon as possible.
          
     Section 17.    Right Certificate Holder Not Deemed a
Stockholder.  No holder of any Right Certificate, as such, shall
be entitled to vote, receive dividends or other distributions or
be deemed for any purpose the holder of the Preferred Shares or
any other securities of the Corporation which may at any time be
issuable upon the exercise or exchange of the Rights represented
thereby, nor shall anything contained herein or in any Right
Certificate be construed to confer upon the holder of any Right
Certificate, as such, any of the rights of a stockholder of the
Corporation 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 other distributions or to exercise any
preemptive or subscription rights, or otherwise, until the Right
or Rights evidenced by such Right Certificate shall have been
exercised or exchanged in accordance with the provisions hereof.

     Section 18.    Concerning the Rights Agent.
          
          (a)  The Corporation agrees to pay to the Rights Agent
     reasonable compensation for all services rendered by the
     Rights Agent hereunder and, from time to time, on demand of
     the Rights Agent, its reasonable expenses and counsel fees
     and other disbursements incurred in the preparation,
     delivery, amendment, administration and execution of this
     Agreement and the exercise and performance of its duties
     hereunder.  The Corporation also agrees to indemnify the
     Rights Agent for, and to hold it harmless against, any loss,
     liability, damage, judgment, fine, penalty, claim, demand,
     settlement, cost or expense, incurred without gross
     negligence, bad faith or willful misconduct on the part of
     the Rights Agent, for any action taken, suffered or omitted
     by the Rights Agent in connection with the acceptance and
     administration of this Agreement or the exercise or
     performance of its duties hereunder, including without
     limitation the reasonable costs and expenses of defending
     against any claim of liability in the premises.  The
     indemnity provided for herein shall survive the expiration
     of the Rights and the termination of this Agreement.
          
          (b)  The Rights Agent shall be authorized and protected
     and shall incur no liability for, or in respect of, any
     action taken, suffered or omitted by it in connection with,
     the acceptance and administration of this Agreement or the
     exercise or performance of its duties hereunder in reliance
     upon any Right Certificate or certificate for Common Shares
     or for other securities of the Corporation, instrument of
     assignment or transfer, power of attorney, endorsement,
     affidavit, letter, notice, instruction, direction, consent,
     certificate, statement, or other paper or document believed
     by it to be genuine and to be signed, executed and, where
     necessary, verified or acknowledged, by the proper Person or
     Persons, or otherwise upon the advice of counsel as set
     forth in Section 20 hereof.
          
     Section 19.    Merger or Consolidation or Change of Name of
Rights Agent.
     
         (a)  Any Person into which the Rights Agent or any
     successor Rights Agent may be merged or with which it may be
     consolidated, or any Person resulting from any merger or
     consolidation to which the Rights Agent or any successor
     Rights Agent shall be a party, or any Person succeeding to
     the stock transfer or all or substantially all of the
     shareholder services business of the Rights Agent or any
     successor Rights Agent, shall be the successor to the Rights
     Agent under this Agreement without the execution or filing
     of any paper or any further act on the part of any of the
     parties hereto, provided that such 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 Right 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 Right Certificates
     so countersigned; and in case at that time any of the Right
     Certificates shall not have been countersigned, any
     successor Rights Agent may countersign such Right
     Certificates either in the name of the predecessor or in the
     name

                               28


<PAGE>

     of the successor Rights Agent; and in all such cases such
     Right Certificates shall have the full force provided in the
     Right Certificates and in this Agreement.
     
          (b)  In case at any time the name of the Rights Agent
     shall be changed and at such time any of the Right
     Certificates shall have been countersigned but not
     delivered, the Rights Agent may adopt the countersignature
     under its prior name and deliver Right Certificates so
     countersigned; and in case at that time any of the Right
     Certificates shall not have been countersigned, the Rights
     Agent may countersign such Right Certificates either in its
     prior name or in its changed name; and in all such cases
     such Right Certificates shall have the full force provided
     in the Right Certificates and in this Agreement.
     
     Section 20.    Duties of Rights Agent.  The Rights Agent
undertakes the duties and obligations, and only the duties and
obligations, expressly imposed by this Agreement (and no implied
duties and obligations) upon the following terms and conditions,
by all of which the Corporation and the holders of Right
Certificates, by their acceptance thereof, shall be bound:
     
          (a)  The Rights Agent may consult with legal counsel
     (who may be legal counsel for the Corporation), and the
     advice or opinion of such counsel shall be full and complete
     authorization and protection to the Rights Agent with
     respect to, and the Rights Agent shall incur no liability
     for or in respect of, any action taken, suffered or omitted
     by it in good faith and in accordance with such advice or
     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 an Acquiring Person and the
     determination of the current market price of any Security)
     be proved or established by the Corporation prior to the
     Rights Agent's taking, suffering or omitting to take any
     action hereunder, such fact or matter (unless other evidence
     in respect thereof be herein specifically prescribed) may be
     deemed to be conclusively proved and established by a
     certificate signed by any one of the Chairman of the Board,
     the Chief Executive Officer, the President, any Vice
     President, the Treasurer or the Secretary of the Corporation
     and delivered to the Rights Agent; and such certificate
     shall be full authorization and protection to the Rights
     Agent with respect to, and the Rights Agent shall incur no
     liability for or in respect of, any action taken, suffered
     or omitted in good faith by it under the provisions of this
     Agreement in reliance upon such certificate.
          
          (c)  The Rights Agent shall be liable hereunder only
     for its own gross negligence, bad faith or willful
     misconduct.  In no case will the Rights Agent be liable for
     special, indirect, punitive, incidental or consequential
     loss or damages of any kind whatsoever (including without
     limitation lost profits), even if the Rights Agent has been
     advised of the possibility of such damages.
          
          (d)  The Rights Agent shall not be liable for or by
     reason of any of the statements of fact or recitals
     contained in this Agreement or in the Right Certificates
     (except its

                               29


<PAGE>

     countersignature on such Right Certificates) or be required
     to verify the same, but all such statements and recitals are
     and shall be deemed to have been made by the Corporation
     only.
     
          (e)  The Rights Agent shall not be under any liability
     or responsibility in respect of the validity of this
     Agreement or the execution and delivery hereof (except the
     due execution hereof  by the Rights Agent) or in respect of
     the validity or execution of any Right Certificate (except
     its countersignature thereof); nor shall it be responsible
     for any breach by the Corporation of any covenant or
     condition contained in this Agreement or in any Rights
     Certificate; nor shall it be responsible for any change in
     the exercisability of the Rights (including without
     limitation the Rights becoming null and void pursuant to
     Section 7(e) hereof) or any adjustment required under the
     provisions of Section 3, 11, 13, 23 or 24 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 Right 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
     Preferred Shares or Common Shares to be issued pursuant to
     this Agreement or any Right Certificate or as to whether any
     Preferred Shares or Common Shares will, when issued, be duly
     authorized, validly issued, fully paid and non-assessable.
          
          (f)  The Corporation agrees that it will perform,
     execute, acknowledge and deliver or cause to be performed,
     executed, acknowledged and delivered all such further and
     other acts, instruments and assurances as may reasonably be
     required by the Rights Agent for the carrying out or
     performing by the Rights Agent of the provisions of this
     Agreement.
          
          (g)  The Rights Agent is hereby authorized and directed
     to accept instructions with respect to the performance of
     its duties hereunder from any one of the Chairman of the
     Board, the Chief Executive Officer, the President, any Vice
     President, the Treasurer or the Secretary of the
     Corporation, and to apply to such officers for advice or
     instructions in connection with its duties, and shall not be
     liable for any action taken, suffered or omitted to be taken
     by it in good faith in accordance with instructions of any
     such officer or for any delay in acting while waiting for
     those instructions.  Any application by the Rights Agent for
     written instructions from the Corporation may, at the option
     of the Rights Agent, set forth in writing any action
     proposed to be taken or omitted by the Rights Agent under
     this Rights Agreement and the date on or after which such
     action shall be taken or such omission shall be effective.
     The Rights Agent shall not be liable for any action taken or
     omitted to be taken by the Rights Agent in accordance with a
     proposal included in any such application on or after the
     date specified in such application (which date shall not be
     less than five Business Days after the date any officer of
     the Corporation actually receives such application, unless
     any such officer shall have consented in writing to an
     earlier date) unless, prior to taking any such action (or
     the effective date in the case of an omission), the Rights
     Agent shall have received written instruction in response to
     such application specifying the action to be taken, suffered
     or omitted.

                               30

          (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
     Corporation or become pecuniarily interested in any
     transaction in which the Corporation may be interested, or
     contract with or lend money to the Corporation or otherwise
     act as fully and freely as though it were not the Rights
     Agent under this Agreement.  Nothing herein shall preclude
     the Rights Agent from acting in any other capacity for the
     Corporation or for any other Person.
          
          (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
     Corporation or any other Person resulting from any such act,
     default, neglect or misconduct, absent gross negligence, bad
     faith or willful misconduct in the selection and continued
     employment thereof.
          
          (j)  No provision of this Agreement shall require the
     Rights Agent to expend or risk its own funds or otherwise
     incur any financial liability in the performance of any of
     its duties hereunder or in the exercise of its rights if
     there shall be reasonable grounds for believing that
     repayment of such funds or adequate indemnification against
     such risk or liability is not reasonably assured to it.
          
          (k)  If, with respect to any Rights Certificate
     surrendered to the Rights Agent for exercise or transfer,
     the certificate attached to the form of assignment or form
     of election to purchase, as the case may be, has either not
     been completed or indicates an affirmative response to
     clause 1 or 2 thereof, the Rights Agent shall not take any
     further action with respect to such requested exercise or
     transfer without first consulting with the Corporation.
          
     Section 21.    Change of Rights Agent.  The Rights Agent or
any successor Rights Agent may resign and be discharged from its
duties under this Agreement upon 30 days' notice in writing
mailed to the Corporation and to each transfer agent of the
Common Shares or Preferred Shares by registered or certified
mail, and, following the Distribution Date, to the holders of the
Right Certificates by first-class mail. The Corporation may
remove the Rights Agent or any successor Rights Agent upon 30
days' notice in writing, mailed to the Rights Agent or successor
Rights Agent, as the case may be, and to each transfer agent of
the Common Shares or Preferred Shares by registered or certified
mail, and, following the Distribution Date, to holders of the
Right Certificates by first-class mail.  If the Rights Agent
shall resign or be removed or shall otherwise become incapable of
acting, the Corporation shall appoint a successor to the Rights
Agent.  If the Corporation shall fail to make such appointment
within a period of 30 days after giving notice of such removal or
after it has been notified in writing of such resignation or
incapacity by the resigning or incapacitated Rights Agent or by
the holder of a Right Certificate (who shall, with such notice,
submit his Right Certificate for inspection by the Corporation),
then the registered holder of any Right Certificate may apply to
any court of competent jurisdiction for the appointment of a new

                               31


<PAGE>

Rights Agent.  Any successor Rights Agent, whether appointed by
the Corporation or by such a court, shall be (a) a Person
organized and doing business under the laws of the United States
or the laws of any state of the United States or the District of
Columbia, in good standing, having an office in the State of New
York, which is authorized under such laws to exercise corporate
trust or stock transfer powers and is subject to supervision or
examination by federal or state authority and which has at the
time of its appointment as Rights Agent a combined capital and
surplus of at least $50,000,000, or (b) an Affiliate of a Person
described in clause (a) of this sentence.  After appointment, the
successor Rights Agent shall be vested with the same powers,
rights, duties and responsibilities as if it had been originally
named as Rights Agent without further act or deed; however, the
predecessor Rights Agent shall deliver and transfer to the
successor Rights Agent any property at the time held by it
hereunder, and execute and deliver any further assurance,
conveyance, act or deed necessary for the purpose.  Not later
than the effective date of any such appointment the Corporation
shall file notice thereof in writing with the predecessor Rights
Agent and each transfer agent of the Common Shares or Preferred
Shares, and, following the Distribution Date, mail a notice
thereof in writing to the registered holders of the Right
Certificates.  Failure to give any notice provided for in this
Section 21, however, or any defect therein, shall not affect the
legality or validity of the resignation or removal of the Rights
Agent or the appointment of the successor Rights Agent, as the
case may be.

     Section 22.    Issuance of New Right Certificates.
Notwithstanding any of the provisions of this Agreement or of the
Rights to the contrary, the Corporation may, at its option, issue
new Right Certificates evidencing Rights in such form as may be
approved by the Board to reflect any adjustment or change in the
Purchase Price and the number or kind or class of shares or other
securities or property purchasable under the Right Certificates
made in accordance with the provisions of this Agreement.

     Section 23.  Redemption and Termination.

          (a)     (i)  The Board may, at its option, redeem all but
          not less than all the then outstanding Rights at a
          redemption price of $.005 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"), at
          any time prior to the earlier of (A) the occurrence of
          a Section 11(a)(ii) Event, or (B) the Final Expiration
          Date.  The Corporation may, at its option, pay the
          Redemption Price either in Common Shares (based on the
          "current per share market price," as defined in
          Section 11(d) hereof, of the Common Shares at the time
          of redemption) or cash; provided, that if the
          Corporation elects to pay the Redemption Price in
          Common Shares, the Corporation shall not be required to
          issue any fractional Common Shares and the number of
          Common Shares issuable to each holder of Rights shall
          be rounded down to the next whole share.
          
                  (ii) In addition, the Board may, at its option, at any
          time following the occurrence of a Section 11(a)(ii)
          Event and the expiration of any period during which

                               32


<PAGE>

          the holder of Rights may exercise the rights under
          Section 11(a)(ii) but prior to any Section 13 Event,
          redeem all but not less than all of the then
          outstanding Rights at the Redemption Price (A) in
          connection with any merger, consolidation, combination,
          sale or other transfer (in one transaction or in a
          series of related transactions) of assets or earning
          power aggregating 50 percent or more of the earning
          power of the Corporation and its Subsidiaries (taken as
          a whole) in which all holders of Common Shares are
          treated alike and not involving (other than as a holder
          of Common Shares being treated like all other such
          holders) an Interested Stockholder, or (B)(1) if and
          for so long as the Acquiring Person is not thereafter
          the Beneficial Owner of 10 percent or more of the Common
          Shares, and (2) at the time of redemption no other
          Persons are Acquiring Persons.

          (b)  In the case of a redemption permitted under
     Section 23(a)(i) hereof, immediately upon the date for
     redemption set forth (or determined in the manner specified)
     in a resolution of the Board 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.  In
     the case of a redemption permitted only under
     Section 23(a)(ii) hereof, evidence of which shall have been
     filed with the Rights Agent, the right to exercise the
     Rights will terminate and represent only the right to
     receive the Redemption Price upon the later of 10 Business
     Days following the giving of such notice or the expiration
     of any period during which the rights under
     Section 11(a)(ii) hereof may be exercised.  The Corporation
     shall promptly give public notice of any such redemption to
     the Rights Agent and the holders of the Rights in the manner
     set forth in Section 26 hereof; provided, however, that the
     failure to give, or any defect in, any such notice shall not
     affect the validity of such redemption.  Within 10 days
     after such date for redemption set forth in a resolution of
     the Board ordering the redemption of the Rights, the
     Corporation shall mail a notice of redemption to all the
     holders of the then outstanding Rights at their last
     addresses as they appear upon the registry books of the
     Rights Agent or, prior to the Distribution Date, on the
     registry books of the transfer agent for the Common Shares.
     Any notice which is mailed in the manner herein provided
     shall be deemed given, whether or not the holder receives
     the notice.  Each such notice of redemption will state the
     method by which the payment of the Redemption Price will be
     made.  Neither the Corporation nor any of its Affiliates or
     Associates may redeem, acquire or purchase for value any
     Rights at any time in any manner other than that
     specifically set forth in this Section 23 or in Section 24
     hereof and other than in connection with the purchase of
     Common Shares prior to the Distribution Date.

          (c)  The Corporation may, at its option, discharge all
     of its obligations with respect to the Rights by (i) issuing
     a press release announcing the manner of redemption of the
     Rights in accordance with this Agreement and (ii) mailing
     payment of the Redemption Price to the registered holders of
     the Rights at their last addresses as they appear on the
     registry books of the Rights Agent or, prior to the
     Distribution Date, on the registry books

                               33

     of the transfer agent of the Common Shares, and, upon such
     action, all outstanding Rights and Right Certificates shall
     be null and void without any further action by the
     Corporation.

     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 null and void pursuant
     to the provisions of Section 7(e) or 11(a)(ii) hereof) for
     Common Shares of the Corporation at an exchange ratio of one
     Common Share 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 Corporation, any Subsidiary of the
     Corporation, any employee benefit plan of the Corporation or
     any such Subsidiary, any Person organized, appointed or
     established by the Corporation for or pursuant to the terms
     of any such plan or any trustee, administrator or fiduciary
     of such a plan), together with all Affiliates and Associates
     of such Person, becomes the Beneficial Owner of 50 percent or
     more of the Common Shares then outstanding.

          (b)  Immediately upon the action of the Board ordering
     the exchange of any Rights pursuant to Section 24(a) hereof
     and without any further action and without any notice, the
     right to exercise such Rights shall terminate and the only
     right thereafter of the holders of such Rights shall be to
     receive that number of Common Shares equal to the number of
     such Rights held by such holder multiplied by the Exchange
     Ratio.  The Corporation shall promptly give public notice
     and notice to the Rights Agent of any such exchange;
     provided, however, that the failure to give, or any defect
     in, such notice shall not affect the validity of such
     exchange.  The Corporation shall promptly mail a notice of
     any such exchange to the Rights Agent and 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 Shares for Rights will
     be effected and, in the event of any partial exchange, the
     number of Rights which will be exchanged.  Any partial
     exchange shall be effected pro rata based on the number of
     Rights (other than Rights which have become void pursuant to
     the provisions of Section 7(e) or 11(a)(ii) hereof) held by
     each holder of Rights.

          (c)  In any exchange pursuant to this Section 24, the
     Corporation, at its option, may substitute Preferred Shares
     (or equivalent preferred shares, as such term is defined in
     Section 11(b) hereof) for some or all of the Common Shares
     exchangeable for Rights, at the initial rate of one
     one-thousandth of a Preferred Share (or equivalent preferred
     share) for each Common Share, as appropriately adjusted to
     reflect adjustments in the voting rights of the Preferred
     Shares pursuant to the terms thereof, so that the fraction
     of a Preferred Share

                               34


<PAGE>

     delivered in lieu of each Common Share shall have the same
     dividend, liquidation and voting rights as one Common Share.
     
          (d)  In the event that there shall not be sufficient
     Common Shares or Preferred Shares issued but not outstanding
     or authorized but unissued to permit any exchange of Rights
     as contemplated in accordance with this Section 24, the
     Corporation shall take all such action as may be necessary
     to authorize additional Common Shares or Preferred Shares
     for issuance upon exchange of the Rights.
     
     Section 25.    Notice of Certain Events.
     
          (a)  In case the Corporation shall, at any time after
     the Distribution Date, propose (i) to pay any dividend
     payable in stock of any class to the holders of its
     Preferred Shares or to make any other distribution to the
     holders of its Preferred Shares (other than a regularly
     quarterly cash dividend), (ii) to offer to the holders of
     its Preferred Shares rights or warrants to subscribe for or
     to purchase any additional Preferred Shares or shares of
     stock of any class or any other securities, rights or
     options, (iii) to effect any reclassification of its
     Preferred Shares (other than a reclassification involving
     only the subdivision or combination of outstanding Preferred
     Shares), (iv) to effect any consolidation or merger into or
     with any other Person (other than a Subsidiary of the
     Corporation in a transaction which does not violate
     Section 11(n) 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 or more
     transactions, of 50 percent or more of the assets or earning
     power of the Corporation and its Subsidiaries (taken as a
     whole) to any other Person or Persons (other than the
     Corporation and/or any of its Subsidiaries in one or more
     transactions each of which does not violate Section 11(n)
     hereof), or (v) to effect the liquidation, dissolution or
     winding up of the Corporation, then, in each such case, the
     Corporation shall give to each holder of a Right
     Certificate, in accordance with Section 26 hereof, a notice
     of such proposed action and shall file a certificate with
     the Rights Agent to that effect, which shall specify the
     record date for the purposes of such dividend, distribution
     or offering 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
     Preferred Shares, if any such date is to be fixed, and such
     notice shall be so given in the case of any action covered
     by clause (i) or (ii) above at least 20 days prior to the
     record date for determining holders of the Preferred Shares
     for purposes of such action, and in the case of any such
     other action, at least 20 days prior to the date of the
     taking of such proposed action or the date of participation
     therein by the holders of the Preferred Shares, whichever
     shall be the earlier.  The failure to give notice required
     by this Section 25 or any defect therein shall not affect
     the legality or validity of the action taken by the
     Corporation or the vote upon any such action.
          
          (b)  Notwithstanding anything in this Agreement to the
     contrary, prior to the Distribution Date, a public filing by
     the Corporation with the U.S. Securities and Exchange

                               35


<PAGE>


     Commission shall constitute sufficient notice to the holders
     of securities of the Corporation, including without
     limitation the Rights, for purposes of this Agreement and no
     other notice need be given to such holders.

          (c)  In case of a Section 11(a)(ii) Event, then (i) the
     Corporation shall, as soon as practicable thereafter, give
     to each holder of a Right Certificate, in accordance with
     Section 26 hereof, a notice of the occurrence of such event,
     which notice shall describe such event and the consequences
     of such event to holders of Rights under Section 11(a)(ii)
     hereof, and (ii) all references in Section 25(a) hereof to
     Preferred Shares shall be deemed thereafter to refer also to
     Common Shares and/or, if appropriate, other securities of
     the Corporation.

this sentence, (i) a time period relating to when the Rights may
be redeemed at such time as the Rights are not then redeemable,
or (ii) 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 Corporation
which states that the proposed supplement or amendment is in
compliance with the terms of this Section 27, the Rights Agent
shall execute such supplement or amendment, provided that such
supplement or amendment does not adversely affect the rights or
obligations of the Rights Agent under this Agreement.  Prior to

(a) interpret the provisions of this Agreement, and (b) make all
determinations deemed necessary or advisable for the
administration of this Agreement (including without limitation a
determination to redeem or exchange or not to redeem or exchange
the Rights or to amend this Agreement and whether any proposed
amendment adversely affects the interests of the holders of Right
Certificates).  For all purposes of this Agreement, any
calculation of the number of Common Shares or other securities
outstanding at any particular time, including for purposes of
determining the particular percentage of such outstanding Common
Shares or any other securities of which any Person is the
Beneficial Owner, shall be made in accordance with the last
sentence of Rule 13d-3(d)(1)(i) of the General Rules and
Regulations under the Exchange Act as in effect on the date of
this Agreement.  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 (the Rights Agent may assume the
Board acted in good faith), shall (x) be final, conclusive and
binding

on the Corporation, the Rights Agent, the holders of the Right
Certificates and all other Persons, and (y) not subject the Board
to any liability to the holders of the Right Certificates.

of this Agreement by or for the benefit of the Corporation or the
Rights Agent shall bind and inure to the benefit of their
respective successors and assigns hereunder.

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

     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.

     Section 32.    Governing Law.  This Agreement, each Right
and each Right Certificate issued hereunder shall be deemed to be
a contract made under the laws of the Republic of Panama and for
all purposes shall be governed by and construed in accordance
with the laws of such country applicable to contracts made and to
be performed entirely within such country, except that all
provisions regarding the rights, duties and obligations of the

with the law of the State of New York, U.S.A., 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, 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

                            Form of
                   Certificate of Designation
                               of
         Series A Junior Participating Preferred Stock
                               of
                      Willbros Group, Inc.

        (Pursuant to the Laws of the Republic of Panama)

     The undersigned, Melvin F. Spreitzer, Executive Vice
President, and John N. Hove, Corporate Secretary, of Willbros
Group, Inc., a corporation organized and existing under the laws
of the Republic of Panama (hereinafter called the "Corporation"),
in accordance with the provisions thereof, DO HEREBY CERTIFY:

     That, pursuant to the authority conferred upon the Board of
Directors of the Corporation (hereinafter called the "Board of
Directors ") by the Articles of Incorporation of the Corporation,
the Board of Directors on April 1, 1999, adopted the following
resolution authorizing a series of Class A Preferred Stock in the
amount and having the designation, voting powers, preferences and
relative, participating, optional and other special rights and
qualifications, limitations and restrictions thereof as follows:

          RESOLVED, that, pursuant to the authority conferred
     upon the Board of Directors in accordance with the
     provisions of the Corporation's Articles of Incorporation,
     the Board of Directors hereby authorizes a series of Class A
     Preferred Stock of the Corporation, with a par value of $.01
     per share, and hereby states the designation and number of
     shares, and fixes the relative rights, preferences, voting
     powers, qualifications, limitations and restrictions thereof
     (in addition to the provisions set forth in the
     Corporation's Articles of Incorporation which are applicable
     to the Preferred Stock or the Class A Preferred Stock of all
     classes and series) as follows:

               Series A Junior Participating Preferred Stock

     Section 1.     Designation, Par Value and Amount.  The
shares of such series shall be designated as "Series A Junior
Participating Preferred Stock" (hereinafter referred to as
"Series A Preferred Stock"), the shares of such series shall be
with par value of $.01 per share, and the number of shares
constituting such series shall be 35,000; provided, however,
that, if more than a total of 35,000 shares of Series A Preferred
Stock shall be issuable upon the exercise of Rights (the
"Rights") issued pursuant to the Rights Agreement, dated as of
April 1, 1999, between the Corporation and ChaseMellon
Shareholder Services, L.L.C., as Rights Agent (as amended from
time to time) (the "Rights Agreement"), the Board of Directors,
pursuant to the laws of the Republic of Panama, shall direct by
resolution or resolutions that a certificate be properly
executed, acknowledged and filed

                               A-1


<PAGE>


providing for the total number of shares of Series A Preferred
Stock authorized to be issued to be increased (to the extent that
the Corporation's Articles of Incorporation then permits) to the
largest number of whole shares (rounded up to the nearest whole
number) issuable upon exercise of the Rights.  Such number of
shares of the Series A Preferred Stock may be increased or
decreased by resolution of the Board of Directors; provided, that
no decrease shall reduce the number of shares of Series A
Preferred Stock to a number less than the number of shares then
outstanding plus the number of shares issuable upon exercise or
conversion of outstanding rights, options or other securities
issued by the Corporation.

     Section 2.     Dividends and Distributions.

          (A)  Subject to the prior and superior rights of the
     holders of any shares of any series of Preferred Stock or
     Class A Preferred Stock ranking prior and superior to the
     shares of Series A Preferred Stock with respect to
     dividends, the holders of shares of Series A Preferred
     Stock, in preference to the holders of shares of any class
     or series of stock of the Corporation ranking junior to the
     Series A Preferred Stock in respect thereof, 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 first business
     day of January, April, July and October of 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 Preferred Stock, in an amount per
     share (rounded to the nearest cent) equal to the greater of
     (a) $10.00 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, par value $.05 per share, of the
     Corporation (the "Common Stock") or a subdivision of the
     outstanding shares of Common Stock, by reclassification or
     otherwise), declared on the Common Stock since the
     immediately preceding Quarterly Dividend Payment Date or,
     with respect to the first Quarterly Dividend Payment Date,
     since the first issuance of any share or fraction of a share
     of Series A Preferred Stock.  In the event the Corporation
     shall at any time after the record date for the initial
     distribution of the Rights pursuant to the Rights Agreement
     (the "Rights Declaration Date") (i) declare or pay any
     dividend on the 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 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 Preferred Stock as provided in paragraph (A) of this
     Section 2 immediately after it declares

                               A-2


<PAGE>


     a dividend or distribution on the Common Stock (other than a
     dividend payable in shares of Common Stock or a subdivision
     of the outstanding shares of Common Stock); provided, that,
     in the event no dividend or distribution shall have been
     declared on the Common Stock during the period between any
     Quarterly Dividend Payment Date and the next subsequent
     Quarterly Dividend Payment Date (or, with respect to the
     first Quarterly Dividend Payment Date, the period between
     the first issuance of any share or fraction of a share of
     Series A Preferred Stock and such first Quarterly Dividend
     Payment Date), a dividend of $10.00 per share on the
     Series A 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 Preferred Stock from the
     Quarterly Dividend Payment Date next preceding the date of
     issue of such shares of Series A 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 and be
     cumulative from the date of issue of such shares, or unless
     the date of issue is a date after the record date for the
     determination of holders of shares of Series A Preferred
     Stock entitled to receive a quarterly dividend and on or
     before such Quarterly Dividend Payment Date, in which case
     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 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
     Preferred Stock entitled to receive payment of a dividend or
     distribution declared thereon, which record date shall be
     not more than 60 days prior to the date fixed for the
     payment thereof.

     Section 3.     Voting Rights.  In addition to any other
voting rights required by law, the holders of shares of Series A
Preferred Stock shall have the following voting rights:

          (A)  Except as provided in paragraph (C) of this
     Section 3 and subject to the provision for adjustment
     hereinafter set forth, each share of Series A 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 or pay
     any dividend on the 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 number of votes
     per share to which holders of shares of Series A 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.

                               A-3


<PAGE>


          (B)  Except as otherwise provided herein or by law, the
     holders of shares of Series A 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, on the date used to determine
     stockholders of record for any meeting of stockholders for
     the election of directors, a default in preference dividends
     (as defined in subparagraph (v) below) on the Series A
     Preferred Stock shall exist, the holders of the Series A
     Preferred Stock shall have the right, voting as a class as
     described in subparagraph (ii) below, to elect two directors
     (in addition to the directors elected by holders of Common
     Stock).  Such right may be exercised (a) at any meeting of
     stockholders for the election of directors or (b) at a
     meeting of the holders of shares of Voting Preferred Stock
     (as hereinafter defined), called for the purpose in
     accordance with the By-laws of the Corporation, until all
     such cumulative dividends (referred to above) shall have
     been paid in full or until non-cumulative dividends have
     been paid regularly for at least one year.

               (ii)  The right of the holders of Series A
     Preferred Stock to elect two directors, as described above,
     shall be exercised as a class concurrently with the rights
     of holders of any other series of Preferred Stock or Class A
     Preferred Stock upon which voting rights to elect such
     directors have been conferred and are then exercisable.  The
     Series A Preferred Stock and any additional series of
     Preferred Stock or Class A Preferred Stock which the
     Corporation may issue and which may provide for the right to
     vote with the Series A  Preferred Stock are collectively
     referred to herein as "Voting Preferred Stock."

               (iii)  Each director elected by the holders of
     shares of Voting Preferred Stock shall be referred to herein
     as a "Preferred Director."  A Preferred Director so elected
     shall continue to serve as such director for a term of one
     year, except that upon any termination of the right of all
     of such holders to vote as a class for Preferred Directors,
     the term of office of the Preferred Directors shall
     terminate.  Any Preferred Director may be removed by, and
     shall not be removed except by, the vote of the holders of
     record of a majority of the outstanding shares of Voting
     Preferred Stock then entitled to vote for the election of
     directors, present (in person or by proxy) and voting
     together as a single class (a) at a meeting of the
     stockholders, or (b) at a meeting of the holders of shares
     of such Voting Preferred Stock, called for the purpose in
     accordance with the By-laws of the Corporation, or (c) by
     written consent signed by the holders of a majority of the
     then outstanding shares of Voting Preferred Stock then
     entitled to vote for the election of directors, taken
     together as a single class.

               (iv)  So long as a default in any preference
     dividends on the Series A Preferred Stock shall exist or the
     holders of any other series of Voting Preferred Stock shall
     be entitled to elect Preferred Directors, (a) any vacancy in
     the office of a Preferred Director may be filled (except as
     provided in the following clause (b)) by an instrument in
     writing signed by the remaining Preferred Director and filed
     with the Corporation and (b) in the case of the removal of
     any Preferred Director, the vacancy may be filled by the
     vote or written

                               A-4


<PAGE>


     consent of the holders of a majority of the outstanding
     shares of Voting Preferred Stock then entitled to vote for
     the election of directors, present (in person or by proxy)
     and voting together as a single class, at such time as the
     removal shall be effected.  Each director appointed as
     aforesaid by the remaining Preferred Director shall be
     deemed, for all purposes hereof, to be a Preferred Director.
     Whenever (x) no default in preference dividends on the
     Series A Preferred Stock shall exist and (y) the holders of
     other series of Voting Preferred Stock shall no longer be
     entitled to elect such Preferred Directors, then the number
     of directors constituting the Board of Directors of the
     Corporation shall be reduced by two.

               (v)  For purposes hereof, a "default in preference
     dividends" on the Series A Preferred Stock shall be deemed
     to have occurred whenever the amount of cumulative and
     unpaid dividends on the Series A Preferred Stock shall be
     equivalent to six full quarterly dividends or more (whether
     or not consecutive), and, having so occurred, such default
     shall be deemed to exist thereafter until, but only until,
     all cumulative dividends on all shares of the Series A
     Preferred Stock then outstanding shall have been paid
     through the last Quarterly Dividend Payment Date or until,
     but only until, non-cumulative dividends have been paid
     regularly for at least one year.

          (D)  Except as set forth herein (or as otherwise
     required by applicable law), holders of Series A Preferred
     Stock shall have no general or special voting rights and
     their consent shall not be required for taking any corporate
     action.

     Section 4.     Certain Restrictions.

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

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

               (ii)  declare or pay dividends, or make any other
     distributions, on any shares of stock ranking on a parity
     (either as to dividends or upon liquidation, dissolution or
     winding up) with the Series A Preferred Stock, except
     dividends paid ratably on the Series A 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
     value any shares of stock ranking junior (either as to
     dividends or upon liquidation, dissolution or winding up) to
     the Series A Preferred Stock; provided, that the Corporation
     may at any time redeem, purchase

                               A-5


<PAGE>


     or otherwise acquire shares of any such junior stock in
     exchange for shares of any stock of the Corporation ranking
     junior (either as to dividends or upon dissolution,
     liquidation or winding up) to the Series A Preferred
     Stock; or

               (iv)  redeem or purchase or otherwise acquire for
     consideration any shares of Series A Preferred Stock, or any
     shares of stock ranking on a parity (either as to dividends
     or upon liquidation, dissolution or winding up) with the
     Series A 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
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 Class A Preferred Stock and may be reissued as
part of another series of Class A Preferred Stock subject to the
conditions and restrictions on issuance set forth herein, in the
Articles of Incorporation of the Corporation, in any other
Certificate of Designation creating a series of Class A Preferred
Stock or as otherwise required or permitted by law.

     Section 6.     Liquidation, Dissolution or Winding Up.

          (A)  Subject to the prior and superior rights of holders of any
     shares of any series of Preferred Stock or Class A Preferred
     Stock ranking prior and superior to the shares of Series A
     Preferred Stock with respect to rights upon liquidation,
     dissolution or winding up (voluntary or otherwise), upon any
     liquidation, dissolution or winding up of the Corporation
     (voluntary or otherwise), 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
     Preferred Stock unless, prior thereto, the holders of shares of
     Series A 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 Preferred Stock unless, prior
     thereto, the holders of shares of Common Stock shall have
     received an amount per share (the "Capital 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 paragraph (C) of this Section 6) (such number in

                               A-6


<PAGE>


     clause (ii) being hereinafter referred to as the "Adjustment
     Number").  Following the payment of the full amount of the
     Series A Liquidation Preference and the Capital Adjustment
     in respect of all outstanding shares of Series A Preferred
     Stock and Common Stock, respectively, holders of Series A
     Preferred Stock and holders 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 and Class
     A Preferred Stock, if any, which rank on a parity with the
     Series A Preferred Stock, then such remaining assets shall
     be distributed ratably to the holders of Series A Preferred
     Stock and 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 Capital 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 or pay any
     dividend on the 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, Combination, etc.  In
case the Corporation shall enter into any consolidation, merger,
combination or other transaction in which the shares of Common
Stock are exchanged for or changed into other stock or
securities, cash and/or any other property, then in any such case
the shares of Series A 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 or pay any dividend on
the 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
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
Preferred Stock shall not be redeemable.

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

     Section 10.    Amendment.  At any time that any shares of
Series A Preferred Stock are outstanding, the Articles of
Incorporation of the Corporation shall not be amended in any
manner which would materially alter or change the powers,
preferences or special rights of the Series A 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 Preferred Stock, voting separately as a class.

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

     IN WITNESS WHEREOF, this Certificate of Designation is
executed on behalf of the Corporation by its duly authorized
officers this       day of April, 1999.

     The number of Rights evidenced by this Right Certificate
(and the number of one one-thousandths of a Preferred Share which
may be purchased upon exercise hereof) set forth above, and the
Purchase Price set forth above, are the number and Purchase Price
as of April 15, 1999, based on the Preferred Shares as
constituted at such date and may have been or in the future be
adjusted as a result of the occurrence of certain events, as more
fully provided in the Rights Agreement.

     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 Right Certificate are beneficially owned by (i) an
Acquiring Person or an Affiliate or Associate of an Acquiring
Person (as such terms are defined in the Rights Agreement),
(ii) a transferee of an Acquiring Person or any such Associate or
Affiliate who becomes a transferee after the Acquiring Person
becomes such, or (iii) under certain circumstances specified in
the Rights Agreement, a transferee of an Acquiring Person or any
such Associate or Affiliate who becomes a transferee prior to or
concurrently with the Acquiring Person becoming such, 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 of one one-thousandth of a Preferred Share or other
securities which may be purchased upon the exercise of the Rights
evidenced by this Right Certificate are subject to modification
and adjustment upon the happening of certain events, including
Triggering Events (as such term is defined in the Rights
Agreement).

     This Right 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 Corporation and the holders of
the Right Certificates, which limitations of rights include the
temporary suspension of the exercisability of such Rights under
the specific circumstances set forth in the Rights Agreement.
Copies of the Rights Agreement are on file at the principal
executive offices of the Corporation and the office of the Rights
Agent designated for such purpose.

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

     Subject to the provisions of the Rights Agreement, the
Rights evidenced by this Certificate (i) may be redeemed by the
Corporation at a redemption price of $.005 per Right (subject to
adjustment as provided in the Rights Agreement) payable either in
cash or the Corporation's

                               B-2


<PAGE>


Common Shares, par value $.05 per share, or (ii) may be exchanged
in whole or in part for Common Shares or Preferred Shares.

     No fractional Preferred Shares or Common Shares will be
issued upon the exercise or exchange of any Right or Rights
evidenced hereby (other than fractions of Preferred Shares which
are one one-thousandth or integral multiples of one
one-thousandth of a Preferred Share, which may, at the election
of the Corporation, 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 Right Certificate shall be entitled to
vote or receive dividends or other distributions or be deemed for
any purpose the holder of the Preferred Shares or of any other
securities of the Corporation which may at any time be issuable
on the exercise or exchange 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
Corporation 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 other distributions or to exercise any
preemptive or subscription rights, or otherwise, until the Right
or Rights evidenced by this Right Certificate shall have been
exercised or exchanged as provided in the Rights Agreement.

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

                                                        Exhibit C

                 SUMMARY OF RIGHTS TO PURCHASE
                      PREFERRED SHARES OF
                      WILLBROS GROUP, INC.

     On April 1, 1999, the Board of Directors of Willbros Group,
Inc. (the "Corporation") declared a distribution of one preferred
share purchase right (a "Right") for each outstanding share of
Common Stock, par value $.05 per share (the "Common Shares"), of
the Corporation.  The distribution is payable to the stockholders
of record of the Corporation on April 15, 1999 (the "Record
Date"), and with respect to Common Shares issued thereafter until
the Distribution Date (as defined below) and, in certain
circumstances, with respect to Common Shares issued after the
Distribution Date.  Except as set forth below, each Right, when
it becomes exercisable, entitles the registered holder to
purchase from the Corporation one one-thousandth of a share of
Series A Junior Participating Preferred Stock, with a par value
of $.01 per share, of the Corporation (the "Preferred Shares") at
a price of $30.00 per one one-thousandth of a Preferred Share
(the "Purchase Price"), subject to adjustment.  The description
and terms of the Rights are set forth in a Rights Agreement, as
the same may be amended from time to time (the "Rights
Agreement"), between the Corporation and ChaseMellon Shareholder
Services, L.L.C., as Rights Agent, dated as of April 1, 1999.

     Initially, the Rights will be attached to all certificates
representing Common Shares then outstanding, and no separate
Right Certificates will be distributed.  The Rights will separate
from the Common Shares upon the earlier to occur of (i) the first
date of public announcement of a person or group of affiliated or
associated persons having acquired beneficial ownership of
15percent or more of the outstanding Common Shares (except
pursuant to a Permitted Offer, as hereinafter defined); or
(ii) 10 days (or such later date as the Board of Directors of the
Corporation (the "Board") may determine) following the
commencement of, or announcement of an intention to make, a
tender offer or exchange offer the consummation of which would
result in a person or group becoming an Acquiring Person (as
hereinafter defined) (the earlier of such dates being called the
"Distribution Date").  A person or group whose acquisition of
Common Shares causes a Distribution Date pursuant to clause (i)
above is an "Acquiring Person."  The first date of public
announcement that a person or group has become an Acquiring
Person is the "Shares Acquisition Date."

     The Rights Agreement provides that, until the Distribution
Date, the Rights will be transferred with and only with the
Common Shares.  Until the Distribution Date (or earlier
redemption or expiration of the Rights) new Common Share
certificates issued after the Record Date upon transfer or new
issuance of Common Shares will contain a notation incorporating
the Rights Agreement by reference.  Until the Distribution Date
(or earlier redemption or expiration of the Rights), the
surrender for transfer of any certificates for Common Shares
outstanding as of the Record Date, even without such notation or
a copy of this Summary of Rights being attached thereto, will
also constitute the transfer of the Rights associated with the
Common Shares represented by such certificate.  As soon as
practicable following the Distribution Date, separate
certificates evidencing the Rights ("Right Certificates") will be
mailed to holders of record of the Common

                               C-1


<PAGE>


Shares as of the close of business on the Distribution Date (and
to each initial record holder of certain Common Shares issued
after the Distribution Date), and such separate Right
Certificates alone will evidence the Rights.

     The Rights are not exercisable until the Distribution Date
and will expire at the close of business on April 15, 2009,
unless earlier redeemed or exchanged by the Corporation as
described below.

     In the event that any person or group becomes an Acquiring
Person (except pursuant to a tender or exchange offer which is
for all outstanding Common Shares at a price and on terms which a
majority of certain members of the Board determines to be
adequate and in the best interests of the Corporation, its
stockholders and other relevant constituencies, other than such
Acquiring Person, its affiliates and associates (a "Permitted
Offer")), each holder of a Right will thereafter have the right
(the "Flip-In Right") to receive upon exercise the number of
Common Shares or of one one-thousandths of a share of Preferred
Shares (or, in certain circumstances, other securities of the
Corporation) having a value (immediately prior to such triggering
event) equal to two times the exercise price of the Right.
Notwithstanding the foregoing, following the occurrence of the
event described above, all Rights that are, or (under certain
circumstances specified in the Rights Agreement) were,
beneficially owned by any Acquiring Person or any affiliate or
associate thereof will be null and void.

     In the event that, at any time following the Shares
Acquisition Date, (i) the Corporation is acquired in a merger or
other business combination transaction in which the holders of
all of the outstanding Common Shares immediately prior to the
consummation of the transaction are not the holders of all of the
surviving corporation's voting power, or (ii) more than 50 percent
of the Corporation's assets or earning power is sold or
transferred, then each holder of a Right (except Rights which
previously have been voided as set forth above) shall thereafter
have the right (the "Flip-Over Right") to receive, upon exercise,
common shares of the acquiring company having a value equal to
two times the exercise price of the Right.  The holder of a Right
will continue to have the Flip-Over Right whether or not such
holder exercises or surrenders the Flip-In Right.

     The Purchase Price payable, and the number of Preferred
Shares, Common Shares or other securities 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
Shares, (ii) upon the grant to holders of the Preferred Shares of
certain rights or warrants to subscribe for or purchase Preferred
Shares at a price, or securities convertible into Preferred
Shares with a conversion price, less than the then current market
price of the Preferred Shares, or (iii) upon the distribution to
holders of the Preferred Shares of evidences of indebtedness or
assets (excluding regular quarterly cash dividends) or of
subscription rights or warrants (other than those referred to
above).

     The Purchase Price and number of outstanding Rights are also
subject to adjustment in the event of a stock split of the Common
Shares or a stock dividend on the Common Shares payable in

                               C-2


<PAGE>


Common Shares or subdivisions, consolidations or combinations of
the Common Shares occurring, in any such case, prior to the
Distribution Date.

     Preferred Shares purchasable upon exercise of the Rights
will not be redeemable.  Each Preferred Share will be entitled to
a minimum preferential quarterly dividend payment of $10.00 per
share but, if greater, will be entitled to an aggregate dividend
per share of 1,000 times the dividend declared per Common Share.
In the event of liquidation, the holders of the Preferred Shares
will be entitled to a minimum preferential liquidation payment of
$1,000 per share; thereafter, and after the holders of the Common
Shares receive a liquidation payment of $1.00 per share, the
holders of the Preferred Shares and the holders of the Common
Shares will share the remaining assets in the ratio of 1,000 to 1
(as adjusted) for each Preferred Share and Common Share so held,
respectively.  Each Preferred Share will have 1,000 votes, voting
together with the Common Shares.  Finally, in the event of any
merger, consolidation or other transaction in which Common Shares
are exchanged, each Preferred Share will be entitled to receive
1,000 times the amount received per Common Share.  These rights
are protected by customary antidilution provisions. In the event
that the amount of accrued and unpaid dividends on the Preferred
Shares is equivalent to six full quarterly dividends or more, the
holders of the Preferred Shares shall have the right, voting as a
class, to elect two directors in addition to the directors
elected by the holders of the Common Shares until all cumulative
dividends on the Preferred Shares have been paid through the last
quarterly dividend payment date or until non-cumulative dividends
have been paid regularly for at least one year.

     With certain exceptions, no adjustment in the Purchase Price
will be required until cumulative adjustments require an
adjustment of at least 1 percent in such Purchase Price.  No
fractional Preferred Shares will be issued (other than fractions
which are one one-thousandth or integral multiples of one one-
thousandth of a Preferred Share, which may, at the election of
the Board, be evidenced by depositary receipts) and in lieu
thereof, an adjustment in cash will be made based on the market
price of the Preferred Shares on the last trading day prior to
the date of exercise.

     At any time prior to the earlier to occur of (i) a person
becoming an Acquiring Person or (ii) the expiration of the
Rights, and under certain other circumstances, the Corporation
may redeem the Rights in whole, but not in part, at a price of
$.005 per Right (the "Redemption Price") which redemption shall
be effective upon the action of the Board.  Additionally,
following the Shares Acquisition Date, the Corporation may redeem
the then outstanding Rights in whole, but not in part, at the
Redemption Price, provided that such redemption is in connection
with a merger or other business combination transaction or series
of transactions involving the Corporation in which all holders of
Common Shares are treated alike but not involving an Acquiring
Person or its affiliates or associates.

     At any time after any person or group becomes an Acquiring
Person and prior to the acquisition by such person or group of
50 percent or more of the outstanding Common Shares, the Board may
exchange the Rights (other than Rights owned by the Acquiring
Person, which will have become void), in whole or in part, at an
exchange ratio of one Common Share, or one

                               C-3

one-thousandth of a Preferred Share (or of a share of a class or
series of the Corporation's preferred stock having equivalent
rights, preferences and privileges), per Right (subject to
adjustment).

     All of the provisions of the Rights Agreement may be amended
by the Board prior to the Distribution Date.  After the
Distribution Date, the provisions of the Rights Agreement may be
amended by the Board only in order to cure any ambiguity, defect
or inconsistency, to make changes which do not adversely affect
the interests of holders of Rights (excluding the interests of
any Acquiring Person), or, subject to certain limitations, to
shorten or lengthen any time period under the Rights Agreement.

     Until a Right is exercised or exchanged, the holder thereof,
as such, will have no right to vote or receive dividends or other
distributions and will have no other rights as a stockholder of
the Corporation.  While the distribution of the Rights will not
be taxable to stockholders of the Corporation, stockholders may,
depending upon the circumstances, recognize taxable income should
the Rights become exercisable or upon the occurrence of certain
events thereafter.

     A copy of the Rights Agreement has been filed with the
U.S. Securities and Exchange Commission as an Exhibit to the
Corporation's Registration Statement on Form 8-A dated
April       , 1999.  A copy of the Rights Agreement is available
      ------
free of charge from the Corporation.  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
hereby incorporated herein by reference.
