         STOCKHOLDER PROTECTION RIGHTS AGREEMENT (as amended from time to time,
this "Agreement"), dated as of ____________, 1997, between Freeport-McMoRan
Sulphur Inc., a Delaware corporation (the "Company"), and MELLON SECURITIES
TRUST COMPANY, a NEW YORK corporation, as Rights Agent (the "Rights Agent",
which term shall include any successor Rights Agent hereunder).

                                 W I T N E S S E T H:

         WHEREAS, the Board of Directors of the Company has (a) authorized and
declared a dividend of one right ("Right") in respect of each share of Common
Stock (as hereinafter defined) held of record as of the close of business on
____________, 1997 (the "Record Time") and (b) authorized the issuance of one
Right in respect of each share of Common Stock issued after the Record Time and
prior to the Separation Time (as hereinafter defined) and, to the extent
provided in Section 5.3, each share of Common Stock issued after the Separation
Time;

         WHEREAS, subject to the terms hereof, each Right entitles the holder
thereof, after the Separation Time, to purchase securities of the Company (or,
in certain cases, of certain other entities) pursuant to the terms and subject
to the conditions set forth herein; and

         WHEREAS, the Company desires to appoint the Rights Agent to act on
behalf of the Company, and the Rights Agent is willing so to act, in connection
with the issuance, transfer, exchange and replacement of Rights Certificates (as
hereinafter defined), the exercise of Rights and other matters referred to
herein;

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

                                      -1-

any additional shares of Common Stock, (ii) any Person who shall become the 
Beneficial Owner of 15% or more of the outstanding shares of Common Stock but 
who acquired shares of Common Stock without any plan or intention to seek or 
affect control of the Company, if such Person promptly thereafter enters into 
and delivers to the Company an irrevocable commitment promptly to divest, and 
thereafter promptly divests (without exercising or retaining any power, 
including voting, with respect to such shares), sufficient shares of Common 
Stock (or securities convertible into, exchangeable into or exercisable for 
Common Stock) so that such Person ceases to be the Beneficial Owner of 15% or 
more of the outstanding shares of Common Stock or (iii) any Person who 
Beneficially Owns shares of Common Stock consisting solely of one or more of 
(A) shares of Common Stock Beneficially Owned pursuant to the grant or 
exercise of an option granted to such Person by the Company in connection 
with an agreement to merge with, or acquire, the Company at a time at which 
there is no Acquiring Person, (B) shares of Common Stock (or securities 
convertible into, exchangeable into or exercisable for Common Stock) 
Beneficially Owned by such Person or its Affiliates or Associates at the time 
of grant of such option or (C) shares of Common Stock (or securities 

                                      -2-

Person's Affiliates or Associates until such tendered security is accepted 
for payment or exchange or (ii) solely because such Person or any of such 
Person's Affiliates or Associates has or shares the power to vote or direct 
the voting of such security pursuant to a revocable proxy given in response 

                                      -3-

shares of a class of stock of the Company registered under Section 12 of the

and shall have impressed on, printed on, written on or otherwise affixed to

    Until the Separation Time (as defined in the Rights Agreement referred to

    redeemed, may be exchanged for shares of Common Stock or other securities

    become void (if they are "Beneficially Owned" by an "Acquiring Person" or
    an Affiliate or Associate thereof, as such terms are defined in the Rights
    Agreement, or by any transferee of any of the foregoing) or may be
    evidenced by separate certificates and may no longer be evidenced by this
    certificate.  The Company will mail or arrange for the mailing of a copy of
    the Rights Agreement to the holder of this certificate without charge
    within five days after the receipt of a written request therefor.

                                      -9-

outstanding at the Record Time shall evidence one Right for each share of 
Common Stock evidenced thereby notwithstanding the absence of the foregoing 
legend.

         2.3  EXERCISE OF RIGHTS; SEPARATION OF RIGHTS.  (a)  Subject to 
Sections 3.1, 5.1 and 5.10 and subject to adjustment as herein set forth, 
each Right will entitle the holder thereof, after the Separation Time and 
prior to the Expiration Time, to purchase, for the Exercise Price, one 
one-hundredth of a share of Preferred Stock.  

         (b)  Until the Separation Time, (i) no Right may be exercised and 
(ii) each Right will be evidenced by the certificate for the associated share 
of Common Stock (together, in the case of certificates issued prior to the 
Record Time, with the letter mailed to the record holder thereof pursuant to 
Section 2.1) and will be transferable only together with, and will be 
transferred by a transfer (whether with or without such letter) of, such 
associated share.  

         (c)  Subject to the terms hereof, after the Separation Time and 
prior to the Expiration Time, the Rights (i) may be exercised and (ii) may be 
transferred independent of shares of Common Stock.  Promptly following the 
Separation Time, the Rights Agent will mail to each holder of record of 
Common Stock as of the Separation Time (other than any Person whose Rights 
have become void pursuant to Section 3.1(b)), at such holder's address as 
shown by the records of the Company (the Company hereby agreeing to furnish 
copies of such records to the Rights Agent for this purpose), (x) a 
certificate (a "Rights Certificate") in substantially the form of Exhibit A 
hereto appropriately completed, representing the number of Rights held by 
such holder at the Separation Time and having such marks of identification or 
designation and such legends, summaries or endorsements printed thereon as 
the Company may deem appropriate and as are not inconsistent with the 

                                      -10-



provisions of this Agreement, or as may be required to comply with any law or 
with any rule or regulation made pursuant thereto or with any rule or 
regulation of any national securities exchange or quotation system on which 
the Rights may from time to time be listed or traded, or to conform to usage, 
and (y) a disclosure statement describing the Rights.

         (d)  Subject to the terms hereof, Rights may be exercised on any 
Business Day after the Separation Time and prior to the Expiration Time by 
submitting to the Rights Agent the Rights Certificate evidencing such Rights 
with an Election to Exercise (an "Election to Exercise") substantially in the 
form attached to the Rights Certificate duly completed, accompanied by 
payment in cash, or by certified or official bank check or money order 
payable to the order of the Company, of a sum equal to the Exercise Price 
multiplied by the number of Rights being exercised and a sum sufficient to 
cover any transfer tax or charge which may be payable in respect of any 
transfer involved in the transfer or delivery of Rights Certificates or the 
issuance or delivery of certificates for shares or depositary receipts (or 
both) in a name other than that of the holder of the Rights being exercised.

         (e)  Upon receipt of a Rights Certificate, with an Election to 
Exercise accompanied by payment as set forth in Section 2.3(d), and subject 
to the terms hereof, the Rights Agent will thereupon promptly (i)(A) 
requisition from the Company's transfer agent stock certificates evidencing 
such number of shares or other securities to be purchased (the Company hereby 
irrevocably authorizing its transfer agent to comply with all such 
requisitions) and (B) if the Company elects pursuant to Section 5.5 not to 
issue certificates representing fractional shares, requisition from the 
depositary selected by the Company depositary receipts representing the 
fractional shares to be purchased or requisition from the Company the amount 
of cash to be paid in lieu of fractional shares in accordance with Section 
5.5 and (ii) after receipt of such certificates, depositary receipts and/or 

                                      -11-



cash, deliver the same to or upon the order of the registered holder of such 
Rights Certificate, registered (in the case of certificates or depositary 
receipts) in such name or names as may be designated by such holder.

         (f)  In case the holder of any Rights shall exercise less than all 
the Rights evidenced by such holder's Rights Certificate, a new Rights 
Certificate evidencing the Rights remaining unexercised will be issued by the 
Rights Agent to such holder or to such holder's duly authorized assigns.

         (g)  The Company covenants and agrees that it will (i) take all such 
action as may be necessary to ensure that all shares delivered upon exercise 
of Rights shall, at the time of delivery of the certificates for such shares 
(subject to payment of the Exercise Price), be duly and validly authorized, 
executed, issued and delivered and fully paid and nonassessable; (ii) take 
all such action as may be necessary to comply with any applicable 
requirements of the Securities Act of 1933 or the Securities Exchange Act of 
1934, and the rules and regulations thereunder, and any other applicable law, 
rule or regulation, in connection with the issuance of any shares upon 
exercise of Rights; and (iii) pay when due and payable any and all federal 
and state transfer taxes and charges which may be payable in respect of the 
original issuance or delivery of the Rights Certificates or of any shares 
issued upon the exercise of Rights, provided that the Company shall not be 
required to pay any transfer tax or charge which may be payable in respect of 
any transfer involved in the transfer or delivery of Rights Certificates or 
the issuance or delivery of certificates for shares in a name other than that 
of the holder of the Rights being transferred or exercised.

         2.4  ADJUSTMENTS TO EXERCISE PRICE; NUMBER OF RIGHTS.  (a)  In the 
event the Company shall at any time after the Record Time and prior to the 
Separation Time (i) declare or pay a dividend on Common Stock payable in 

                                      -12-



Common Stock, (ii) subdivide the outstanding Common Stock or (iii) combine 
the outstanding Common Stock into a smaller number of shares of Common Stock, 
(x) the Exercise Price in effect after such adjustment will be equal to the 
Exercise Price in effect immediately prior to such adjustment divided by the 
number of shares of Common Stock (the "Expansion Factor") that a holder of 
one share of Common Stock immediately prior to such dividend, subdivision or 
combination would hold thereafter as a result thereof and (y) each Right held 
prior to such adjustment will become that number of Rights equal to the 
Expansion Factor, and the adjusted number of Rights will be deemed to be 
distributed among the shares of Common Stock with respect to which the 
original Rights were associated (if they remain outstanding) and the shares 
issued in respect of such dividend, subdivision or combination, so that each 
such share of Common Stock will have exactly one Right associated with it.  
Each adjustment made pursuant to this paragraph shall be made as of the 
payment or effective date for the applicable dividend, subdivision or 
combination.

         In the event the Company shall at any time after the Record Time and 
prior to the Separation Time issue any shares of Common Stock otherwise than 
in a transaction referred to in the preceding paragraph, each such share of 
Common Stock so issued shall automatically have one new Right associated with 
it, which Right shall be evidenced by the certificate representing such 
share.  To the extent provided in Section 5.3, Rights shall be issued by the 
Company in respect of shares of Common Stock that are issued or sold by the 
Company after the Separation Time.

         (b)  In the event the Company shall at any time after the Record 
Time and prior to the Separation Time issue or distribute any securities or 
assets in respect of, in lieu of or in exchange for Common Stock (other than 

                                      -13-



pursuant to a regular periodic cash dividend or a dividend paid solely in 
Common Stock) whether by dividend, in a reclassification or recapitalization 
(including any such transaction involving a merger, consolidation or share 
exchange), or otherwise, the Company shall make such adjustments, if any, in 
the Exercise Price, number of Rights and/or securities or other property 
purchasable upon exercise of Rights as the Board of Directors of the Company, 
in its sole discretion, may deem to be appropriate under the circumstances in 
order to adequately protect the interests of the holders of Rights generally, 
and the Company and the Rights Agent shall amend this Agreement as necessary 
to provide for such adjustments.

         (c)  Each adjustment to the Exercise Price made pursuant to this 
Section 2.4 shall be calculated to the nearest cent.  Whenever an adjustment 
to the Exercise Price is made pursuant to this Section 2.4, the Company shall 
(i) promptly prepare a certificate setting forth such adjustment and a brief 
statement of the facts accounting for such adjustment, (ii) promptly file 
with the Rights Agent and with each transfer agent for the Common Stock a 
copy of such certificate and (iii) mail a brief summary thereof to each 
holder of Rights.

         (d)  Irrespective of any adjustment or change in the securities 
purchasable upon exercise of the Rights, the Rights Certificates theretofore 
and thereafter issued may continue to express the securities so purchasable 
which were expressed in the initial Rights Certificates issued hereunder.

         2.5  DATE ON WHICH EXERCISE IS EFFECTIVE.  Each person in whose name 
any certificate for shares is issued upon the exercise of Rights shall for 
all purposes be deemed to have become the holder of record of the shares 
represented thereby on, and such certificate shall be dated, the date upon 
which the Rights Certificate evidencing such Rights was duly surrendered and 
payment of the Exercise Price for such Rights (and any applicable taxes and 
other governmental charges payable by the exercising holder hereunder) was 

                                      -14-



made; PROVIDED, HOWEVER, that if the date of such surrender and payment is a 
date upon which the stock transfer books of the Company are closed, such 
person shall be deemed to have become the record holder of such shares on, 
and such certificate shall be dated, the next succeeding Business Day on 
which the stock transfer books of the Company are open.  

         2.6  EXECUTION, AUTHENTICATION, DELIVERY AND DATING OF RIGHTS 
CERTIFICATES.  (a)  The Rights Certificates shall be executed on behalf of 
the Company by its Chairman of the Board, President or its Treasurer, under 
its corporate seal reproduced thereon attested by its Secretary or one of its 
Assistant Secretaries.  The signature of any of these officers on the Rights 
Certificates may be manual or facsimile.

         Rights Certificates bearing the manual or facsimile signatures of 
individuals who were at any time the proper officers of the Company shall 
bind the Company, notwithstanding that such individuals or any of them have 
ceased to hold such offices prior to the countersignature and delivery of 
such Rights Certificates.

         Promptly after the Company learns of the Separation Time, the 
Company will notify the Rights Agent of such Separation Time and will deliver 
Rights Certificates executed by the Company to the Rights Agent for 
countersignature, and, subject to Section 3.1(b), the Rights Agent shall 
manually countersign and deliver such Rights Certificates to the holders of 
the Rights pursuant to Section 2.3(c) hereof.  No Rights Certificate shall be 
valid for any purpose unless manually countersigned by the Rights Agent.

         (b)  Each Rights Certificate shall be dated the date of 
countersignature thereof.

         2.7  REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE.  (a)  
After the Separation Time, the Company will cause to be kept a register (the 
"Rights Register") in which, subject to such reasonable regulations as it may 

                                      -15-



prescribe, the Company will provide for the registration and transfer of 
Rights.  The Rights Agent is hereby appointed "Rights Registrar" for the 
purpose of maintaining the Rights Register for the Company and registering 
Rights and transfers of Rights after the Separation Time as herein provided.  
In the event that the Rights Agent shall cease to be the Rights Registrar, 
the Rights Agent will have the right to examine the Rights Register at all 
reasonable times after the Separation Time.

         After the Separation Time and prior to the Expiration Time, upon 
surrender for registration of transfer or exchange of any Rights Certificate, 
and subject to the provisions of Section 2.7(c) and (d), the Company will 
execute, and the Rights Agent will countersign and deliver, in the name of 
the holder or the designated transferee or transferees, as required pursuant 
to the holder's instructions, one or more new Rights Certificates evidencing 
the same aggregate number of Rights as did the Rights Certificate so 
surrendered.

         (b)  Except as otherwise provided in Section 3.1(b), all Rights 
issued upon any registration of transfer or exchange of Rights Certificates 
shall be the valid obligations of the Company, and such Rights shall be 
entitled to the same benefits under this Agreement as the Rights surrendered 
upon such registration of transfer or exchange.

         (c)  Every Rights Certificate surrendered for registration of 
transfer or exchange shall be duly endorsed, or be accompanied by a written 
instrument of transfer in form satisfactory to the Company or the Rights 
Agent, as the case may be, duly executed by the holder thereof or such 
holder's attorney duly authorized in writing.  As a condition to the issuance 
of any new Rights Certificate under this Section 2.7, the Company may require 
the payment of a sum sufficient to cover any tax or other governmental charge 
that may be imposed in relation thereto.

                                      -16-



         (d)  The Company shall not be required to register the transfer or
exchange of any Rights after such Rights have become void under Section 3.1(b),
been exchanged under Section 3.1(c) or been redeemed or terminated under
Section 5.1.

         2.8  MUTILATED, DESTROYED, LOST AND STOLEN RIGHTS CERTIFICATES.  (a) 
If any mutilated Rights Certificate is surrendered to the Rights Agent prior 
to the Expiration Time, then, subject to Sections 3.1(b) and 5.1, the Company 
shall execute and the Rights Agent shall countersign and deliver in exchange 
therefor a new Rights Certificate evidencing the same number of Rights as did 
the Rights Certificate so surrendered.

         (b)  If there shall be delivered to the Company and the Rights Agent 
prior to the Expiration Time (i) evidence to their satisfaction of the 
destruction, loss or theft of any Rights Certificate and (ii) such security 
or indemnity as may be required by them to save each of them and any of their 
agents harmless, then, subject to Sections 3.1(b) and 5.1 and in the absence 
of notice to the Company or the Rights Agent that such Rights Certificate has 
been acquired by a BONA FIDE purchaser, the Company shall execute and upon 
its request the Rights Agent shall countersign and deliver, in lieu of any 
such destroyed, lost or stolen Rights Certificate, a new Rights Certificate 
evidencing the same number of Rights as did the Rights Certificate so 
destroyed, lost or stolen.

         (c)  As a condition to the issuance of any new Rights Certificate 
under this Section 2.8, the Company may require the payment of a sum 
sufficient to cover any tax or other governmental charge that may be imposed 
in relation thereto and any other expenses (including the fees and expenses 
of the Rights Agent) connected therewith.

         (d)  Every new Rights Certificate issued pursuant to this Section 
2.8 in lieu of any destroyed, lost or stolen Rights Certificate shall 

                                      -17-



evidence an original additional contractual obligation of the Company, 
whether or not the destroyed, lost or stolen Rights Certificate shall be at 
any time enforceable by anyone, and shall be entitled to all the benefits of 
this Agreement equally and proportionately with any and all other Rights duly 
issued hereunder.

         2.9  PERSONS DEEMED OWNERS.  Prior to due presentment of a Rights 
Certificate (or, prior to the Separation Time, the associated Common Stock 
certificate) for registration of transfer, the Company, the Rights Agent and 
any agent of the Company or the Rights Agent may deem and treat the person in 
whose name such Rights Certificate (or, prior to the Separation Time, such 
Common Stock certificate) is registered as the absolute owner thereof and of 
the Rights evidenced thereby for all purposes whatsoever, including the 
payment of the Redemption Price and neither the Company nor the Rights Agent 
shall be affected by any notice to the contrary.  As used in this Agreement, 
unless the context otherwise requires, the term "holder" of any Rights shall 
mean the registered holder of such Rights (or, prior to the Separation Time, 
the associated shares of Common Stock).

         2.10  DELIVERY AND CANCELLATION OF CERTIFICATES.  All Rights 
Certificates surrendered upon exercise or for registration of transfer or 
exchange shall, if surrendered to any person other than the Rights Agent, be 
delivered to the Rights Agent and, in any case, shall be promptly cancelled 
by the Rights Agent.  The Company may at any time deliver to the Rights Agent 
for cancellation any Rights Certificates previously countersigned and 
delivered hereunder which the Company may have acquired in any manner 
whatsoever, and all Rights Certificates so delivered shall be promptly 
cancelled by the Rights Agent.  No Rights Certificates shall be countersigned 
in lieu of or in exchange for any Rights Certificates cancelled as provided 
in this Section 2.10, except as expressly permitted by this Agreement.  The 
Rights Agent shall destroy all cancelled Rights Certificates and deliver a 
certificate of destruction to the Company.

                                      -18-



         2.11  AGREEMENT OF RIGHTS HOLDERS.  Every holder of Rights by 
accepting the same consents and agrees with the Company and the Rights Agent 
and with every other holder of Rights that:

         (a)  prior to the Separation Time, each Right will be transferable 
only together with, and will be transferred by a transfer of, the associated 
share of Common Stock;

         (b)  after the Separation Time, the Rights Certificates will be 
transferable only on the Rights Register as provided herein; 

         (c)  prior to due presentment of a Rights Certificate (or, prior to 
the Separation Time, the associated Common Stock certificate) for 
registration of transfer, the Company, the Rights Agent and any agent of the 
Company or the Rights Agent may deem and treat the person in whose name the 
Rights Certificate (or, prior to the Separation Time, the associated Common 
Stock certificate) is registered as the absolute owner thereof and of the 
Rights evidenced thereby for all purposes whatsoever, and neither the Company 
nor the Rights Agent shall be affected by any notice to the contrary;

         (d)  Rights beneficially owned by certain Persons will, under the 
circumstances set forth in Section 3.1(b), become void; and

         (e)  this Agreement may be supplemented or amended from time to time 
pursuant to Section 2.4(b) or 5.4 hereof.

                                     ARTICLE III

                            ADJUSTMENTS TO THE RIGHTS IN 

                          THE EVENT OF CERTAIN TRANSACTIONS


         3.1  FLIP-IN.  (a)  In the event that prior to the Expiration Time a
Flip-in Date shall occur, the Company shall take such action as shall be

                                      -19-



necessary to ensure and provide that, except as provided in this Section 3.1, 
each Right shall constitute the right to purchase from the Company, upon 
exercise thereof in accordance with the terms hereof (but subject to Section 
5.10), that number of shares of Common Stock having an aggregate Market Price 
on the Stock Acquisition Date equal to twice the Exercise Price for an amount 
in cash equal to the Exercise Price (such right to be appropriately adjusted 
in order to protect the interests of the holders of Rights generally in the 
event that on or after such Stock Acquisition Date an event of a type 
analogous to any of the events described in Section 2.4(a) or (b) shall have 
occurred with respect to the Common Stock).

         (b)  Notwithstanding the foregoing,  any Rights that are or were 
Beneficially Owned on or after the Stock Acquisition Date by an Acquiring 
Person or an Affiliate or Associate thereof or by any transferee, direct or 
indirect, of any of the foregoing shall become void and any holder of such 
Rights (including transferees) shall thereafter have no right to exercise or 
transfer such Rights under any provision of this Agreement.  If any Rights 
Certificate is presented for assignment or exercise and the Person presenting 
the same will not complete the certification set forth at the end of the form 
of assignment or notice of election to exercise and provide such additional 
evidence of the identity of the Beneficial Owner and its Affiliates and 
Associates (or former Beneficial Owners and their Affiliates and Associates) 
as the Company shall reasonably request, then the Company shall be entitled 
conclusively to deem the Beneficial Owner thereof to be an Acquiring Person 
or an Affiliate or Associate thereof or a transferee of any of the foregoing 
and accordingly will deem the Rights evidenced thereby to be void and not 
transferable or exercisable.

         (c)  The Board of Directors of the Company may, at its option, at 
any time after a Flip-in Date and prior to the time that an Acquiring Person 

                                      -20-



becomes the Beneficial Owner of more than 50% of the outstanding shares of 
Common Stock, elect to exchange all (but not less than all) the then 
outstanding Rights (which shall not include Rights that have become void 
pursuant to the provisions of Section 3.1(b)) for shares of Common Stock at 
an exchange ratio of one share of Common Stock per Right, appropriately 
adjusted in order to protect the interests of holders of Rights generally in 
the event that after the Separation Time an event of a type analogous to any 
of the events described in Section 2.4(a) or (b) shall have occurred with 
respect to the Common Stock (such exchange ratio, as adjusted from time to 
time, being hereinafter referred to as the "Exchange Ratio").

         Immediately upon the action of the Board of Directors of the Company 
electing to exchange the Rights, without any further action and without any 
notice, the right to exercise the Rights will terminate and each Right (other 
than Rights that have become void pursuant to Section 3.1(b)) will thereafter 
represent only the right to receive a number of shares of Common Stock equal 
to the Exchange Ratio.  Promptly after the action of the Board of Directors 
electing to exchange the Rights, the Company shall give notice thereof 
(specifying the steps to be taken to receive shares of Common Stock in 
exchange for Rights) to the Rights Agent and the holders of the Rights (other 
than Rights that have become void pursuant to Section 3.1(b)) outstanding 
immediately prior thereto by mailing such notice in accordance with Section 
5.9.

         Each Person in whose name any certificate for shares is issued upon 
the exchange of Rights pursuant to this Section 3.1(c) or Section 3.1(d) 
shall for all purposes be deemed to have become the holder of record of the 
shares represented thereby on, and such certificate shall be dated, the date 
upon which the Rights Certificate evidencing such Rights was duly surrendered 
and payment of any applicable taxes and other governmental charges payable by 
the holder was made; PROVIDED, HOWEVER, that if the date of such surrender 

                                      -21-



and payment is a date upon which the stock transfer books of the Company are 
closed, such Person shall be deemed to have become the record holder of such 
shares on, and such certificate shall be dated, the next succeeding Business 
Day on which the stock transfer books of the Company are open.

         (d)  Whenever the Company shall become obligated under Section 
3.1(a) or (c) to issue shares of Common Stock upon exercise of or in exchange 
for Rights, the Company, at its option, may substitute therefor shares of 
Preferred Stock, at a ratio of one one-hundredth of a share of Preferred 
Stock for each share of Common Stock so issuable.

         (e)  In the event that there shall not be sufficient treasury shares 
or authorized but unissued shares of Common Stock or Preferred Stock of the 
Company to permit the exercise or exchange in full of the Rights in 
accordance with Section 3.1(a) or (c), the Company shall either (i) call a 
meeting of stockholders seeking approval to cause sufficient additional 
shares to be authorized (provided that if such approval is not obtained the 
Company will take the action specified in clause (ii) of this sentence) or 
(ii) take such action as shall be necessary to ensure and provide, to the 
extent permitted by applicable law and any agreements or instruments in 
effect on the Stock Acquisition Date to which it is a party, that each Right 
shall thereafter constitute the right to receive, (x) at the Company's 
option, either (A) in return for the Exercise Price, debt or equity 
securities or other assets (or a combination thereof) having a fair value 
equal to twice the Exercise Price, or (B) without payment of consideration 
(except as otherwise required by applicable law), debt or equity securities 
or other assets (or a combination thereof) having a fair value equal to the 
Exercise Price, or (y) if the Board of Directors of the Company elects to 
exchange the Rights in accordance with Section 3.1(c), debt or equity 
securities or other assets (or a combination thereof) having a fair value 
equal to the product of the Market Price of a share of Common Stock on the 
Flip-in Date times the Exchange Ratio in effect on the Flip-in Date, where in 

                                      -22-



any case set forth in (x) or (y) above the fair value of such debt or equity 
securities or other assets shall be as determined in good faith by the Board 
of Directors of the Company, after consultation with a nationally recognized 
investment banking firm.  

         3.2  FLIP-OVER.  (a)  Prior to the Expiration Time, the Company 
shall not enter into any agreement with an Acquiring Person (or any of its 
Affiliates or Associates) with respect to, consummate or permit to occur any 
Flip-over Transaction or Event unless and until it shall have entered into a 
supplemental agreement with the Flip-over Entity, for the benefit of the 
holders of the Rights, providing that, upon consummation or occurrence of the 
Flip-over Transaction or Event (i) each Right shall thereafter constitute the 
right to purchase from the Flip-over Entity, upon exercise thereof in 
accordance with the terms hereof, that number of shares of Flip-over Stock of 
the Flip-over Entity having an aggregate Market Price on the date of 
consummation or occurrence of such Flip-over Transaction or Event equal to 
twice the Exercise Price for an amount in cash equal to the Exercise Price 
(such right to be appropriately adjusted in order to protect the interests of 
the holders of Rights generally in the event that after such date of 
consummation or occurrence an event of a type analogous to any of the events 
described in Section 2.4(a) or (b) shall have occurred with respect to the 
Flip-over Stock) and (ii) the Flip-over Entity shall thereafter be liable 
for, and shall assume, by virtue of such Flip-over Transaction or Event and 
such supplemental agreement, all the obligations and duties of the Company 
pursuant to this Agreement.  The provisions of this Section 3.2 shall apply 
to successive Flip-over Transactions or Events.

         (b)  Prior to the Expiration Time, unless the Rights will be 
redeemed pursuant to  Section 5.1 hereof in connection therewith, the Company 
shall not enter into any agreement with respect to, consummate or permit to 

                                      -23-



occur any Flip-over Transaction or Event if at the time thereof there are any 
rights, warrants or securities outstanding or any other arrangements, 
agreements or instruments that would eliminate or otherwise diminish in any 
material respect the benefits intended to be afforded by this Rights 
Agreement to the holders of Rights upon consummation of such transaction.

                                   ARTICLE IV

                                THE RIGHTS AGENT

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

         (b)  The Rights Agent shall be protected and shall incur no 
liability for or in respect of any action taken, suffered or omitted by it in 
connection with its administration of this Agreement in reliance upon any 
certificate for securities purchasable upon exercise of Rights, Rights 
Certificate, certificate for other securities of the Company, instrument of 

                                      -24-



assignment or transfer, power of attorney, endorsement, affidavit, letter, 
notice, direction, consent, certificate, statement, or other paper or 
document believed by it to be genuine and to be signed, executed and, where 
necessary, verified or acknowledged, by the proper person or persons.

         4.2  MERGER OR CONSOLIDATION OR CHANGE OF NAME OF RIGHTS AGENT.  (a) 
Any corporation into which the Rights Agent or any successor Rights Agent may 
be merged or with which it may be consolidated, or any corporation resulting 
from any merger or consolidation to which the Rights Agent or any successor 
Rights Agent is a party, or any corporation succeeding to the stockholder 
services business of the Rights Agent or any successor Rights Agent, will 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 4.4 hereof.  In case 
at the time such successor Rights Agent succeeds to the agency created by 
this Agreement any of the Rights Certificates have been countersigned but not 
delivered, any such successor Rights Agent may adopt the countersignature of 
the predecessor Rights Agent and deliver such Rights Certificates so 
countersigned; and in case at that time any of the Rights Certificates have 
not been countersigned, any successor Rights Agent may countersign such 
Rights Certificates either in the name of the predecessor Rights Agent or in 
the name of the successor Rights Agent; and in all such cases such Rights 
Certificates will have the full force provided in the Rights Certificates and 
in this Agreement.

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

                                      -25-



name or in its changed name; and in all such cases such Rights Certificates 
shall have the full force provided in the Rights Certificates and in this 
Agreement.

         4.3  DUTIES OF RIGHTS AGENT.  The Rights Agent undertakes the duties 
and obligations imposed by this Agreement upon the following terms and 
conditions, by all of which the Company and the holders of Rights 
Certificates, by their acceptance thereof, shall be bound:

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

         (b)  Whenever in the performance of its duties under this Agreement 
the Rights Agent deems it necessary or desirable that any fact or matter be 
proved or established by the Company prior to taking or suffering any action 
hereunder, such fact or matter (unless other evidence in respect thereof be 
herein specifically prescribed) may be deemed to be conclusively proved and 
established by a certificate signed by a person believed by the Rights Agent 
to be the Chairman of the Board, the President or any Vice President and by 
the Treasurer or any Assistant Treasurer or the Secretary or any Assistant 
Secretary of the Company and delivered to the Rights Agent; and such 
certificate will be full authorization to the Rights Agent for any action 
taken or suffered in good faith by it under the provisions of this Agreement 
in reliance upon such certificate.

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

         (d)  The Rights Agent will not be liable for or by reason of any of 
the statements of fact or recitals contained in this Agreement or in the 
certificates for securities purchasable upon exercise of Rights or the Rights 

                                      -26-



Certificates (except its countersignature thereof) or be required to verify 
the same, but all such statements and recitals are and will be deemed to have 
been made by the Company only.

         (e)  The Rights Agent will not be under any responsibility in 
respect of the validity of this Agreement or the execution and delivery 
hereof (except the due authorization, execution and delivery hereof by the 
Rights Agent) or in respect of the validity or execution of any certificate 
for securities purchasable upon exercise of Rights or Rights Certificate 
(except its countersignature thereof); nor will it be responsible for any 
breach by the Company of any covenant or condition contained in this 
Agreement or in any Rights Certificate; nor will it be responsible for any 
change in the exercisability of the Rights (including the Rights becoming 
void pursuant to Section 3.1(b) hereof) or any adjustment required under the 
provisions of Section 2.4, 3.1 or 3.2 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 after receipt of the certificate contemplated by Section 
2.4 describing any such adjustment); nor will it by any act hereunder be 
deemed to make any representation or warranty as to the authorization or 
reservation of any securities purchasable upon exercise of Rights or any 
Rights or as to whether any securities purchasable upon exercise of Rights 
will, when issued, be duly and validly authorized, executed, issued and 
delivered and fully paid and nonassessable.

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

                                      -27-



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

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

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

         4.4  CHANGE OF RIGHTS AGENT.  The Rights Agent may resign and be 
discharged from its duties under this Agreement upon 90 days' notice (or such 
lesser notice as is acceptable to the Company) in writing mailed to the 
Company and to each transfer agent of Common Stock by registered or certified 

                                      -28-



mail, and to the holders of the Rights in accordance with Section 5.9.  The 
Company may remove the Rights Agent upon 30 days' notice in writing, mailed 
to the Rights Agent and to each transfer agent of the Common Stock by 
registered or certified mail, and to the holders of the Rights in accordance 
with Section 5.9.  If the Rights Agent should resign or be removed or 
otherwise become incapable of acting, the Company will appoint a successor to 
the Rights Agent.  If the Company fails to make such appointment within a 
period of 30 days after 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 any Rights (which holder shall, with such notice, 
submit such holder's Rights Certificate for inspection by the Company), then 
the holder of any Rights may apply to any court of competent jurisdiction for 
the appointment of a new Rights Agent.  Any successor Rights Agent, whether 
appointed by the Company or by such a court, shall be a corporation organized 
and doing business under the laws of the United States or of the State of New 
York, in good standing, having its principal office in the State of New York, 
which is authorized under such laws to exercise the powers of the Rights 
Agent contemplated by this Agreement 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.  After appointment, the successor Rights Agent will be vested 
with the same powers, rights, duties and responsibilities as if it had been 
originally named as Rights Agent without further act or deed; but the 
predecessor Rights Agent shall deliver and transfer to the successor Rights 
Agent any property at the time held by it hereunder, and execute and deliver 
any further assurance, conveyance, act or deed necessary for the purpose.  
Not later than the effective date of any such appointment, the Company will 
file notice thereof in writing with the predecessor Rights Agent and each 
transfer agent of the Common Stock, and mail a notice thereof in writing to 
the holders of the Rights.  Failure to give any notice provided for in this 
Section 4.4, 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.

                              ARTICLE V 
                            MISCELLANEOUS

         5.1  REDEMPTION.  (a)  The Board of Directors of the Company may, at 
its option, at any time prior to the close of business on the Flip-in Date, 
elect to redeem all (but not less than all) the then outstanding Rights at 
the Redemption Price and the Company, at its option, may pay the Redemption 
Price either in cash or shares of Common Stock or other securities of the 
Company deemed by the Board of Directors, in the exercise of its sole 
discretion, to be at least equivalent in value to the Redemption Price.

         (b)  Immediately upon the action of the Board of Directors of the 
Company electing to redeem the Rights (or, if the resolution of the Board of 
Directors electing to redeem the Rights states that the redemption will not 
be effective until the occurrence of a specified future time or event, upon 
the occurrence of such future time or event), without any further action and 
without any notice, the right to exercise the Rights will terminate and each 
Right will thereafter represent only the right to receive the Redemption 
Price in cash or securities, as determined by the Board of Directors.  
Promptly after the Rights are redeemed, the Company shall give notice of such 
redemption to the Rights Agent and the holders of the then outstanding Rights 
by mailing such notice in accordance with Section 5.9.

         5.2  EXPIRATION.  The Rights and this Agreement shall expire at the 
Expiration Time and no Person shall have any rights pursuant to this 
Agreement or any Right after the Expiration Time, except, if the Rights are 
exchanged or redeemed, as provided in Section 3.1(c), 3.1(d), 3.1(e), 3.2 or 
5.1 hereof.

                                      -30-



         5.3  ISSUANCE OF NEW RIGHTS CERTIFICATES.  Notwithstanding any of 
the provisions of this Agreement or of the Rights to the contrary, the 
Company may, at its option, issue new Rights Certificates evidencing Rights 
in such form as may be approved by its Board of Directors to reflect any 
adjustment or change in the number or kind or class of shares of stock 
purchasable upon exercise of Rights made in accordance with the provisions of 
this Agreement.  In addition, in connection with the issuance or sale of 
shares of Common Stock by the Company following the Separation Time and prior 
to the Redemption Time or Expiration Time pursuant to the terms of securities 
convertible or redeemable into shares of Common Stock or to options, in each 
case issued or granted prior to, and outstanding at, the Separation Time, the 
Company shall issue to the holders of such shares of Common Stock, Rights 
Certificates representing the appropriate number of Rights in connection with 
the issuance or sale of such shares of Common Stock; PROVIDED, HOWEVER, in 
each case, (i) no such Rights Certificate shall be issued, if, and to the 
extent that, the Company shall be advised by counsel that such issuance would 
create a significant risk of material adverse tax consequences to the Company 
or to the Person to whom such Rights Certificates would be issued, (ii) no 
such Rights Certificates shall be issued if, and to the extent that, 
appropriate adjustment shall have otherwise been made in lieu of the issuance 
thereof, and (iii) the Company shall have no obligation to distribute Rights 
Certificates to any Acquiring Person or Affiliate or Associate of an 
Acquiring Person or any transferee of any of the foregoing.

         5.4  SUPPLEMENTS AND AMENDMENTS.  The Company and the Rights Agent 
may from time to time supplement or amend this Agreement without the approval 
of any holders of Rights (i) prior to the close of business on the Flip-in 
Date, in any respect and (ii) after the close of business on the Flip-in 
Date, to make any changes that the Company may deem necessary or desirable 
and which shall not materially adversely affect the interests of the holders 

                                      -31-



of Rights generally or in order to cure any ambiguity or to correct or 
supplement any provision contained herein which may be inconsistent with any 
other provisions herein or otherwise defective.  The Rights Agent will duly 
execute and deliver any supplement or amendment hereto requested by the 
Company which satisfies the terms of the preceding sentence.

         5.5  FRACTIONAL SHARES.  If the Company elects not to issue 
certificates representing fractional shares upon exercise or redemption of 
Rights, the Company shall, in lieu thereof, in the sole discretion of the 
Board of Directors, either (a) evidence such fractional shares by depositary 
receipts issued pursuant to an appropriate agreement between the Company and 
a depositary selected by it, providing that each holder of a depositary 
receipt shall have all of the rights, privileges and preferences to which 
such holder would be entitled as a beneficial owner of such fractional share, 
or (b) sell such shares on behalf of the holders of Right and pay to the 
registered holder of such Rights the appropriate fraction of price per share 
received upon such sale.

         5.6  RIGHTS OF ACTION.  Subject to the terms of this Agreement 
(including Section 3.1(b)), rights of action in respect of this Agreement, 
other than rights of action vested solely in the Rights Agent, are vested in 
the respective holders of the Rights; and any holder of any Rights, without 
the consent of the Rights Agent or of the holder of any other Rights, may, on 
such holder's own behalf and for such holder's own benefit and the benefit of 
other holders of Rights, enforce, and may institute and maintain any suit, 
action or proceeding against the Company to enforce, or otherwise act in 
respect of, such holder's right to exercise such holder's Rights in the 
manner provided in such holder's Rights Certificate and in this Agreement.  
Without limiting the foregoing or any remedies available to the holders of 
Rights, it is specifically acknowledged that the holders of Rights would not 

                                      -32-



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.

         5.7  HOLDER OF RIGHTS NOT DEEMED A STOCKHOLDER.  No holder, as such, 
of any Rights shall be entitled to vote, receive dividends or be deemed for 
any purpose the holder of shares or any other securities which may at any 
time be issuable on the exercise of such Rights, nor shall anything contained 
herein or in any Rights Certificate be construed to confer upon the holder of 
any Rights, as such, any of the rights of a stockholder of the Company or any 
right to vote for the election of directors or upon any matter submitted to 
stockholders at any meeting thereof, or to give or withhold consent to any 
corporate action, or to receive notice of meetings or other actions affecting 
stockholders (except as provided in Section 5.8 hereof), or to receive 
dividends or subscription rights, or otherwise, until such Rights shall have 
been exercised or exchanged in accordance with the provisions hereof.

         5.8  NOTICE OF PROPOSED ACTIONS.  In case the Company shall propose 
after the Separation Time and prior to the Expiration Time (i) to effect or 
permit (in cases where the Company's permission is required) occurrence of 
any Flip-in Date or Flip-over Transaction or Event or (ii) to effect the 
liquidation, dissolution or winding up of the Company, then, in each such 
case, the Company shall give to each holder of a Right, in accordance with 
Section 5.9 hereof, a notice of such proposed action, which shall specify the 
Flip-in Date or the date on which such Flip-over Transaction or Event, 
liquidation, dissolution, or winding up is to take place, and such notice 
shall be so given at least 20 Business Days prior to the date of the taking 
of such proposed action.  

                                      -33-

determines in good faith that some action will need to be taken pursuant to 
Section 3.1(a), (b), (d) or (e) or to comply with federal or state securities 
laws, the Company may suspend the exercisability of the Rights for a period 
of up to ninety (90) days following the date of the occurrence of the

under this Agreement; but this Agreement shall be for the sole and exclusive 
benefit of the Company, the Rights Agent and the holders of the Rights.
